    Peptic ulcer disease remains a common problem and it most frequently due to the presence of an Helicobacter pylori infection or use of non-steroidal anti-inflammatory drugs (NSAIDs). Dyspepsia is neither sensitive or specific for diagnosing peptic ulcer disease. The approach to patients with dyspepsia is to arrive at a definitive diagnosis without unnecessary exposure to invasive or costly diagnostic procedures. Non-invasive testing is preferred with endoscopy being reserved for those with alarm markers or above a specified age (e.g., 55 years in Western countries). Patients negative for H. pylori infection should receive an empiric trial of acid suppression for 4 to 8 weeks and if beneficial it can be continued.

    VacA and CagA serological responses were detected in pediatric patients: 44 and 56%, respectively, in peptic ulcer (PU) patients, 33.3 and 44.4% in active chronic gastritis (ACG) patients, and 23.2 and 39.2% in non-ACG patients. Higher seroprevalence to CagA+VacA and to CagA+VacA+35-kDa antigen was found among PU patients. However, a low level of sensitivity and specificity was found for indirect detection of PU patients.

    cagA(+) Helicobacter pylori strains have been linked to more severe gastric inflammation, peptic ulcer disease, and gastric cancer in adults, but there have been few studies of cagA in children. We examined the relationship between H. pylori cagA status and clinical status in Japanese children. Forty H. pylori-positive children were studied: 15 with nodular gastritis, 5 with gastric ulcers, and 20 with duodenal ulcers. H. pylori status was confirmed by biopsy-based tests and serum anti-H. pylori immunoglobulin G (IgG) antibody. As controls, 77 asymptomatic children with sera positive for anti-H. pylori IgG were enrolled. Levels of IgG antibodies to CagA in serum were measured by an antigen-specific enzyme-linked immunosorbent assay. In 16 patients with successful H. pylori eradication, posttreatment levels of CagA and H. pylori IgG antibodies also were studied. The CagA antibody seropositivities of asymptomatic controls (81.8%) and patients with nodular gastritis, gastric ulcers, and duodenal ulcers (80.0 to 95.0%) were not significantly different. Compared with pretreatment levels of CagA antibodies, posttreatment levels decreased progressively and significantly. We conclude that, as in Japanese adults, a high prevalence of cagA(+) H. pylori strains was found in Japanese children, and that there was no association with nodular gastritis or peptic ulcer disease. In the assessment of eradicative therapies, monitoring of serum anti-CagA antibodies does not appear to offer any direct benefit over monitoring of anti-H. pylori antibodies.

    This contribution reviews briefly the history of the discovery and characterization of peptic activity; secretory models and current concepts regarding the regulation of pepsinogen secretion; and evidence that pepsin is a necessary co-factor for gastroduodenal mucosal injury. Several animal studies indicate that peptic activity is required for acid- and nonsteroidal anti-inflammatory drug-induced gastroduodenal ulceration. A more vigorous approach to the development of anti-peptic drugs for the treatment of peptic ulcer disease is encouraged. Images Figure 1 PMID:9041694

    Chronic atrophic gastritis (CAG) is closely correlated with gastric cancer and is predominant in Japan. Epidemiologically, food habits are the primary factor in both CAG and gastric cancer. Two potential serum markers for CAG have recently been investigated, i.e., the concentration of serum pepsinogen (PG) and the presence of serum antibodies against Helicobacter pylori. Serum PG I and II and the PG I:PG II ratio have been reported to be useful as indicators of recurrent peptic ulcer and for screening of patients at risk from gastric cancer. In this study, we examined PG I and II in serum from 483 patients by RIA (DAINABOT), and endoscopic examination performed in the same patients before serological assay revealed CAG in 68, peptic ulcer in 91, and gastric cancer in 48. Analysis of the mean values according to patients age showed that CAG patients in their forties to eighties had low (< 40 ng/ml) levels of PG I, peptic ulcer patients in their teens to eighties had high (> or = 70 ng/ml) levels, except for those in their seventies, and gastric cancer patients in their twenties to sixties had low (< 3.0) PG I:PG II ratios, except for those in their sixties. Thus serum PG assay has potential utility for detection of CAG, peptic ulcer, and gastric cancer.

  8. Cytotoxic isolates of Helicobacter pylori from Peptic Ulcer Diseases decrease K+-dependent ATPase Activity in HeLa cells

    PubMed Central

    2003-01-01

    Background Helicobacter pylori is a Gram negative bacterium that plays a central role in the etiology of chronic gastritis and peptic ulcer diseases. However, not all H. pylori positive cases develop advanced disease. This discriminatory behavior has been attributed to the difference in virulence of the bacteria. Among all virulence factors, cytotoxin released by H. pylori is the most important factor. In this work, we studied variation in H. pylori isolates from Indian dyspeptic patients on the basis of cytotoxin production and associated changes in K+-dependent ATPase (one of its targets) enzyme activity in HeLa cells. Methods The patients were retrospectively grouped on the basis of endoscopic and histopathological observation as having gastritis or peptic ulcer. The HeLa cells were incubated with the broth culture filtrates (BCFs) of H. pylori isolates from patients of both groups and observed for the cytopathic effects: morphological changes and viability. In addition, the K+-dependent ATPase activity was measured in HeLa cells extracts. Results The cytotoxin production was observed in 3/7 (gastritis) and 4/4 (peptic ulcer) H. pylori isolates. The BCFs of cytotoxin producing H. pylori strains reduced the ATPase activity of HeLa cells to 40% of that measured with non-cytotoxin producing H. pylori strains (1.33 μmole Pi/mg protein and 3.36 μmole Pi/mg protein, respectively, p < 0.05). The decreased activity of ATPase enzyme or the release of cytotoxin also correlated with the increased pathogenicity indices of the patients. Conclusions Our results suggest that the isolation of cytotoxic H. pylori is more common in severe form of acid peptic diseases (peptic ulcer) than in gastritis patients from India. Also the cytotoxin released by H. pylori impairs the ion-transporting ATPase and is a measure of cytotoxicity. PMID:14604441

    Prevalence of chronic gastritis has markedly declined in developed populations during the past decades. However, chronic gastritis is still one of the most common serious pandemic infections with such severe killing sequelae as peptic ulcer or gastric cancer. Globally, on average, even more than half of people may have a chronic gastritis at present. Helicobacter pylori infection in childhood is the main cause of chronic gastritis, which microbial origin is the key for the understanding of the bizarre epidemiology and course of the disease. A life-long and aggressive inflammation in gastritis results in destruction (atrophic gastritis) of stomach mucosa with time (years and decades). The progressive worsening of atrophic gastritis results subsequently in dysfunctions of stomach mucosa. Atrophic gastritis will finally end up in a permanently acid-free stomach in the most extreme cases. Severe atrophic gastritis and acid-free stomach are the highest independent risk conditions for gastric cancer known so far. In addition to the risks of malignancy and peptic ulcer, acid-free stomach and severe forms of atrophic gastritis may associate with failures in absorption of essential vitamins, like vitamin B12, micronutrients (like iron, calcium, magnesium and zinc), diet and medicines.

    Establishment of Helicobacter pylori infection as an etiologic agent of peptic ulcer disease and other gastric pathologies marked a revolution in gastroenterology which spurred an enormous interest in gastric physiology and immunology research. The association was soon also demonstrated in children as well. Application of antimicrobial therapies have proven remarkably efficacious in eradicating H. pylori and curing pediatric patients of duodenal ulcers as well as gastritis, negating a lifetime of ineffective therapy and life-threatening disease. Countries with high H. pylori prevalence and where H. pylori associated gastric cancer remains a primary cause of death due to cancer however would benefit from childhood vaccination. Studies in rodents and humans utilizing oral vaccination with bacterial exotoxin adjuvants demonstrated potential for limiting H. pylori colonization in the stomach. Almost 25 y of vaccine research recently culminated in a phase III clinical trial of over 4,000 children aged 6-15 y old to test an oral vaccine consisting of the H. pylori urease B subunit genetically fused to the E. coli heat labile toxin. Vaccination was demonstrated to have an efficacy of over 70%. Vaccination may now serve as an effective strategy to significantly reduce H. pylori associated disease in children throughout the world.

    Tardipherone is capable of maximum absorption in the initial portion of small intestine, iron being in its retarding form, which fact ensures a prolonged action of the drug, mucoprotease being a part of tardipherone composition acting to guard gastric and duodenal mucosae against irritating effect of iron. Tardipherone was found to be efficacious in treating patients with ulcer disease complicated by bleeding. Under its effect the hemogram indices get normalized as does the ratio of aggressive to protective factors of gastric juice, which factors play a major part in the emergent relapse of the illness. The use of tardipherone was found to be justified in the treatment of patients with chronic atrophic gastritis, being associated with gratifying shifts in the clinical picture of the condition and improvement in the hemogram characteristics.

    A study of gastric biopsies with optical and electronical microscope from patients with gastritis in different stages of evolution was realized. The ultraestructural results consist in phenomenal alterations at the epitelium level, apparition of bodies of mielinic aspects in the inside of the Oxintcs cells, reduction of the number of this and the peptic cells and even the disappearance of the last. There is an increase of the mucous cells with mitotic changes, notable hyperplasia of the arget cells and intestinal metaplasia in the advanced cases. In the stroma is demonstrative the infiltration of plasmatic cells having a endoplasmatic reticule in different stages of activity, linphocytes and macrophagous full of primary and secondary lysosomas. A very important fact is the increase of the argentofilous cells and its probably relation with the appearing of the gastritis. The presence of the plasma cells and lynphocyts mark the role that takes the immunitary reaction in this process.

    An investigator blind trial was performed comparing bismuth salicylate, erythromycin ethylsuccinate, and placebo in the treatment of Campylobacter pyloridis associated gastritis in patients without peptic ulceration. Fifty patients fulfilled the study criteria. There was a strong correlation between the presence of C pyloridis and histologically confirmed gastritis. Clearance of organisms led to improvement of the gastritis. C pyloridis was cleared from 15 patients; of these, 13 had gastritis initially, which resolved in 12. Conversely, gastritis resolved in only four of 32 patients not cleared of organisms (p less than 0.0001). There was significantly greater improvement in endoscopic appearances in the patients cleared of C pyloridis compared with those whose infection persisted (p less than 0.001). In the three treatment groups organisms were cleared from 14 of 18 patients receiving the locally active bismuth salicylate, only one of 15 patients receiving erythromycin ethylsuccinate, and none of 17 patients taking placebo. These findings suggest that the ideal antimicrobial for the successful eradication of C pyloridis associated gastritis should be locally active, stable at low pH, and should penetrate gastric mucus. The resolution of gastritis and improvement in endoscopic appearances associated with clearance of C pyloridis support the view that these organisms may play a part in this condition.

    Gastritis--inflammation of the stomach--is a frequently cited differential yet rarely characterized diagnosis in cases of canine anorexia and vomiting. Although the list of rule-outs for acute or chronic gastritis is extensive, a review of the veterinary literature reveals fewer than 15 articles that have focused on clinical cases of canine gastritis over the last 25 years. The dog frequently appears in the human literature as an experimentally manipulated model for the study of endoscopic techniques or the effect of medications on gastric mucosa. In the veterinary patient, cases of acute gastritis are rarely pursued with the complete diagnostic armamentarium, and cases of chronic gastritis are rarely found to occur as an entity isolated from the rest of the gastrointestinal tract. This article focuses on those findings most clinically relevant to cases of canine gastritis in veterinary medicine.

    Probiotic lactic acid bacteria are being proposed to cure peptic ulcers by reducing colonization of Helicobacter pylori within the stomach mucosa and by eradicating already established infection. In lieu of that, in vitro inhibitory activity of pediocin-producing probiotic Pediococcus acidilactici BA28 was evaluated against H. pylori by growth inhibition assays. Further, chronic gastritis was first induced in two groups of C57BL/6 mice by orogastric inoculation with H. pylori with polyethylene catheter, and probiotic P. acidilactici BA28 was orally administered to study the eradication and cure of peptic ulcer disease. H. pylori and P. acidilactici BA28 were detected in gastric biopsy and fecal samples of mice, respectively. A probiotic treatment with P. acidilactici BA28, which is able to eliminate H. pylori infection and could reverse peptic ulcer disease, is being suggested as a co-adjustment with conventional antibiotic treatment.

    OBJECTIVE: To present a current review about pathogenesis, pathophysiology, diagnosis, and treatment of peptic ulcer disease in children, based on the reviewed publications and the author personal experience. METHODS: We revised the most relevant articles about peptic ulcer in children, published from the last 20 years. RESULTS: The gastroduodenal peptic ulcer is very common in adults, mostly in the developing countries. Although it is less frequent in children, the optical fibroendoscopy has improved the number of diagnosed cases. The peptic ulcer is classified as its etiology in primary and secondary. The secondary peptic ulcer is related to a subjacent disease or use of drugs, while the primary ulcer happens in the absence of underlying systemic diseases The primary duodenal ulcer is the most common presentation, and there are strong evidences of the H. pylori association in the etiology. Clinical presentation changes with age and ulcer type. Secondary ulcers are mostly acute and sometimes dramatic, while the primary ones have a chronic evolution mostly similar to patients with functional recurrent abdominal pain, but the presence of epigastric pain, feeding-related pain, vomiting, bleeding, familiar history for peptic ulcer, nocturnal pain, and male gender are strongly related to peptic ulcer. The acid antisecretory agents have great efficacy on relieving symptoms and solving ulcerate lesion, although the H. pylori eradication itself prevents primary duodenal ulcer recurrence. CONCLUSIONS: The primary peptic ulcer involve many factors in Its etiopathogenesis, being H. pylori the most important of them Although there isn t yet a ideal therapeutic course. The antibiotics play an important role in peptic ulcer and the H. pylori research must be done for na accurate diagnosis and treatment.

    Gastritis is associated with peptic ulcer, gastroenterostomy, pernicious anemia, and exposure to nitrosamines. Once established, the process may be self-perpetuating, resulting in atrophy, metaplasia, dysplasia, and neoplasia. This can be explained by the process of endogenous nitrosation of amines in the inflamed gastric mucosa. Evidence is presented to support this hypothesis. Several drugs given parenterally have been identified as mutagenic nitroso compounds in homogenates of human and canine antral mucosa. Nitrite for this process is apparently derived from the inflamed mucosa. Different amines appear to be nitrosated at different places in the antrum, suggesting the presence of site-specific enzymes that control these reactions.

    In the present paper, we report a case of rare collagenous gastritis. The patient was a 25-year-old man who had experienced nausea, abdominal distention and epigastralgia since 2005. Esophagogastroduodenoscopy (EGD) carried out at initial examination by the patient's local doctor revealed an extensively discolored depression from the upper gastric body to the lower gastric body, mainly including the greater curvature, accompanied by residual mucosa with multiple islands and nodularity with a cobblestone appearance. Initial biopsies sampled from the nodules and accompanying atrophic mucosa were diagnosed as chronic gastritis. In August, 2011, the patient was referred to Tohoku University Hospital for observation and treatment. EGD at our hospital showed the same findings as those by the patient's local doctor. Pathological findings included a membranous collagen band in the superficial layer area of the gastric mucosa, which led to a diagnosis of collagenous gastritis. Collagenous gastritis is an extremely rare disease, but it is important to recognize its characteristic endoscopic findings to make a diagnosis.

The study aims to evaluate the anti-inflammatory properties and gastritis protection activity of C. penicillata against indomethacin in adult guinea pigs. The study was divided into four parts: firstly, the optimum dose of extract as anti-inflammatory effect was determined. Secondly, the acute anti-inflammatory effect of extract were estimated. Thirdly, the repeated doses of extract against chronic inflammation was estimated. The anti-inflammatory activity of extract was compared with indomethacin as a prototype of drug against inflammation. Fourthly, the gastritis protection properties of extract with/without indomethacin were performed. The results showed that a 400 mg/kg of 10% ethanol extract produced the maximum of anti-inflammatory effect. Also, the single dose of extract was equipotent for indomethacin (10 mg/kg), but shorter in duration with regard to acute anti-inflammatory effect. In addition, the repeated doses of extract against chronic inflammation were less potent than indomethacin with regard to ulcerogenic effect. On the other hand, extract-indomethacin combination reduced the gastritis effect of indomethacin based on ulcer index and histological study. PMID:27433522

    There are a few studies of the association between genetic polymorphisms and the risks of acetylsalicylic acid (aspirin)-induced ulcer or its complications. Two single nucleotide polymorphisms (SNP) of cyclooxygenase-1 (COX-1), A-842G and C50T, exhibited increased sensitivity to aspirin and had lower prostaglandin synthesis capacity, lacking statistical significance in the association with bleeding peptic ulcer. A recent Japanese study indicated that the number of COX-1-1676T alleles was a significant risk factor for peptic ulcer in users of non-steroidal anti-inflammatory drugs (NSAIDs). There are some genetic polymorphisms for aspirin resistance, such as platelet membrane glycoproteins, thromboxane A2 (TXA2) receptor, platelet activating factor acetylhydrolase and coagulation factor XIII; however, data on the frequency of gastrointestinal (GI) events in these variants are lacking. Carrying the CYP2C9 variants is reported a significantly increased risk of non-aspirin NSAID-related GI bleeding. The polymorphisms of interleukin-1beta (IL-1beta) and tumor necrosis factor-alpha (TNF-alpha) have been associated with development of peptic ulcer or gastric cancer. In a recent investigation, carriage of the IL-1beta-511 T allele was significantly associated with peptic ulcer among low-dose aspirin users. Hypoacidity in corpus gastritis related to polymorphisms of pro-inflammatory cytokines seems to reduce NSAIDs or aspirin-related injury. Data on which polymorphisms are significant risk factors for GI events in aspirin users are still lacking and further large-scale clinical studies are required.

    AIM: Helicobacter pylori (H pylori) has been linked to chronic gastritis, peptic ulcers, gastric cancer and MALT-lymphoma. Conventional invasive tests are less sensitive than non-invasive tests in diagnosing H pylori infection in patients with bleeding peptic ulcers. Polymerase chain reaction is a sensitive and accurate method for diagnosing H pylori infection. The aim of this study was to evaluate the diagnostic role of mucosal polymerase chain reaction for H pylori infection in patients with bleeding peptic ulcers. METHODS: In patients with bleeding, non-bleeding peptic ulcers and chronic gastritis, we checked rapid urease test, histology, bacterial culture and mucosal polymerase chain reaction for detecting H pylori infection. Positive H pylori infection was defined as positive culture or both a positive histology and a positive rapid urease test. For mucosal polymerase chain reaction of H pylori, we checked vacA (s1a, s1b, s1c, s2, m1, m1T, m2), iceA1, iceA2 and cag A. RESULTS: Between October 2000 and April 2002, 88 patients with bleeding peptic ulcers (males/females: 60/28, gastric ulcers/duodenal ulcers: 55/33), 81 patients with non-bleeding peptic ulcers (males/females: 54/27, gastric ulcers/duodenal ulcers: 45/36) and 37 patients with chronic gastritis (males/females: 24/13) were enrolled in this study. In patients with bleeding peptic ulcers, non-bleeding peptic ulcers and chronic gastritis, 45 patients (51%), 71 patients (88%) and 20 patients (54%) respectively were found to have positive H pylori infection (P<0.001). In patients with bleeding peptic ulcers, non-bleeding peptic ulcers and chronic gastritis, polymerase chain reaction for H pylori infection was positive in 54 patients (61%), 70 patients (86%) and 20 patients (54%) respectively (P<0.001). The sensitivity, positive predictive value and diagnostic accuracy of mucosal polymerase reaction for H pylori infection were significantly lower in patients with bleeding peptic ulcers (84%, 79% and 81

    Background: Peptic ulcer disease (PUD), encompassing gastric and duodenal ulcers is the most prevalent gastrointestinal disorder. The pathophysiology of PUD involves an imbalance between offensive factors like acid, pepsin and defensive factors like nitric oxide and growth factors. The clinical evaluation of antiulcer drugs showed tolerance, incidence of relapses and side-effects that make their efficacy arguable. An indigenous drug like Musa sapientum possessing fewer side-effects is the major thrust area of present day research, aiming at a better and safer approach for the management of PUD. Material and Methods: The unripe plantain bananas (Musa sapientum) were shade-dried, powdered and used for phytochemical analysis and as antiulcer drug. In our present study Group I rats served as control and were treated with saline, Group II was indomethacin-induced ulcerated rats, Group III received aqueous extract of Musa sapientum along with indomethacin and Group IV received esomeprazole along with indomethacin for 21 days. The anti-ulcerogenic activity was investigated by performing hematological, mucosal, antioxidant profile in comparison with the standard drug esomeprazole. Results: Our findings from High - Performance Thin Layer Chromatography (HPTLC) analysis showed that Musa sapientum has an active compound a monomeric flavonoid (leucocyanidin) with anti-ulcerogenic activity. Results were expressed as mean ± SD. All our results are in congruous with the results of standard drug esomeprazole. Conclusion: It could be clearly concluded that administration of the aqueous extract of Musa sapientum at the dose used in this study tends to ameliorate ulcers. Its use in indigenous medicine should be scientifically scrutinized with further research. PMID:22224045

    We conducted a double-blind randomized treatment study on patients affects by non-ulcer dyspepsia in whom multiple biopsy specimens showed active gastritis. Patients were given either 3 g/day of sucralfate (n = 39) or 600 mg/day of sulglycotide (n = 50) for 6 wk, a glycopeptide isolated from pig duodenum constituents. Endoscopy was carried out at baseline and at the end of treatment. We took biopsies from the gastric body (twice) and antrum (six times) at each endoscopy in order to determine grade and extent of gastritis and Helicobacter pylori colonization. Both treatments induced a marked regression of active gastritis (sucralfate group: p less than 0.05 and p less than 0.0001, respectively, in body and in antrum; sulglycotide group: p less than 0.01 and p less than 0.001, respectively). Conversely, Helicobacter pylori colonization remained unchanged at the end of the treatments. At baseline, a close relationship was found between grade of active inflammation in each biopsy and Helicobacter pylori density. After therapy, the association was lost in each treatment group. These results suggest that there can be a remission of active gastritis in patients with non-ulcer dyspepsia even without changes in Helicobacter pylori colonization. This result can be achieved by enhancing the protective properties of the gastric mucosa.

    This study aimed to elucidate groups at high risk of developing cancer among patients with serologically identified Helicobacter pylori infection and nonatrophic stomach. Annual endoscopy was performed for a mean of 5.4 years in 496 asymptomatic middle-aged men who were H. pylori antibody-positive and pepsinogen (PG) test-negative. Subjects were stratified according to the activity of H. pylori-associated gastritis measured by serum levels of PG and H. pylori antibody, and/or by endoscopic findings of rugal hyperplastic gastritis (RHG), and cancer development was investigated. During the study period, seven cases of cancer developed in the cohort (incidence rate, 261/100,000 person-years), with 85.7% developing in the group showing a PGI/II ratio ≤ 3.0, reflecting active inflammation-based high PGII levels. Cancer incidence was significantly higher in this group (750/100,000 person-years) than in groups with less active gastritis. Furthermore, cancer incidence for this group was significantly higher in the subgroup with high H. pylori antibody titers than in the low-titer subgroup. Meanwhile, endoscopic findings revealed that 11.7% of subjects showed RHG reflecting localized highly active inflammation, and cancer risk was significantly higher in patients with RHG than in patients without. Combining the two serum tests and endoscopic examination for RHG allowed identification of subjects with more active gastritis and higher cancer risk. No cancer development was observed in these high-risk subjects after H. pylori eradication. Subjects with highly active gastritis identified by the two serological tests and endoscopic RHG constitute a group at high risk of cancer development with H. pylori-infected nonatrophic stomach.

    Gastritis is defined as inflammation of the gastric mucosa. In histological terms, it is distinguishable into two main categories, i.e. non-atrophic and atrophic. In the gastric mucosa, atrophy is defined as the loss of appropriate glands. There are several etiological types of gastritis, their different etiology being related to different clinical manifestations and pathological features. Atrophic gastritis (resulting mainly from long-standing Helicobacter pylori infection) is a major risk factor for the onset of (intestinal type) gastric cancer. The extent and site of the atrophic changes correlate significantly with the cancer risk. The current format for histology reporting in cases of gastritis fails to establish an immediate link between gastritis phenotype and risk of malignancy. Building on current knowledge of the biology of gastritis, an international group of pathologists [Operative Link for Gastritis Assessment (OLGA)] has proposed a system for reporting gastritis in terms of its stage (the OLGA Staging System): this system places the histological phenotypes of gastritis on a scale of progressively increasing gastric cancer risk, from the lowest (Stage 0) to the highest (Stage IV). The aim of this tutorial is to provide unequivocal information on how to standardize histology reports on gastritis in diagnostic practice.

    Background: Avipattikar churna, a poly-herbal formulation, is one of the popular ayurvedic formulations which is used for peptic ulcer diseases but the scientific documentation with regards to its effect for the indication is lacking. Aims: This study was carried out to evaluate the anti-secretory and the anti-ulcerogenic activities of the churna and to compare its activity with that of ranitidine in a pyloric ligated model of rats. Material and methods: Four groups of rats with 6 animals in each served as the ulcer controls, churna low dose (500 mg/kg), churna high dose (750mg/kg) and ranitidine (25mg/kg). The control group rats received only vehicle (2% (v/v) gum acacia), while the rats of the other groups received the respective dose of the churna or ranitidine which was suspended in the vehicle. The treatments were given twice a day, orally, for two days. After 1 hour of the last dose, pyloric ligations were performed and the rats were sacrificed for evaluation after four hours of the ligations. The gastric contents were collected and its volume, pH and acidity were measured. The numbers of ulcers and their lengths were measured which were used to calculate the gastric irritancy index and the curative ratio. The histological examinations of the gastric tissues were also performed. Results: The churna, in both doses, significantly decreased the volumes of the gastric contents, the ulcer score, the length of the ulcer, the gastric irritancy index and pH increased as compared to those in the control group. The effects of the churna were comparable to that of ranitidine. The histopathological evaluation of the gastric tissue also supported the results. Conclusion: Avipattikar churna has anti-secretory and anti-ulcerogenic effects which are comparable to those of ranitidine in peptic ulcer diseases. PMID:23905120

    Human gastric diseases have shown significant changes in the activity and expression of superoxide dismutase (SOD) isoforms. The aim of this study was to detect Mn-SOD activity and expression in the tissue of gastric mucosa, primarily in chronic gastritis (immunohistochemical Helicobacter pylori-negative gastritis, without other pathohistological changes) and to evaluate their possible connection with pathohistological diagnosis. We examined 51 consecutive outpatients undergoing endoscopy for upper gastrointestinal symptoms. Patients were classified based on their histopathological examinations and divided into three groups: 51 patients (archive samples between 2004-2009) with chronic immunohistochemical Helicobacter pylori-negative gastritis (mononuclear cells infiltration were graded as absent, moderate, severe) divided into three groups. Severity of gastritis was graded according to the updated Sydney system. Gastric tissue samples were used to determine the expression of Mn-SOD with anti-Mn-SOD Ab immunohistochemically. The Mn-SOD expression was more frequently present in specimens with severe and moderate inflammation of gastric mucosa than in those with normal mucosa. In patients with normal histological finding, positive immunoreactivity of Mn-SOD was not found. Our results determine the changes in Mn-SOD expression occurring in the normal gastric mucosa that had undergone changes in the intensity of chronic inflammatory infiltrates in the lamina propria.

    Helicobacter pylori (H. pylori) infection is mainly acquired in childhood and is frequent in developing countries. The infection is associated with chronic gastritis in all infected children, but peptic ulcer disease develops in a small number of them. In our country, H. pylori infection and associated peptic ulcer disease are common. In eastern Turkey, we found peptic ulcer disease in 13.2% of children who underwent endoscopic examination. Peptic ulcers were mostly gastric ulcers and H. pylori-positive in the studied population, and most of the children were admitted due to abdominal pain. As there are no well-established criteria leading directly to diagnosis, pediatricians should include H. pylori infection and peptic ulcer disease in the differential diagnosis list when evaluating children with abdominal pain, failure to thrive and upper gastrointestinal system bleeding.

    In the past 30 years, medicine has witnessed an unprecedented evolution in acid-peptic disorder management, fueled by major advances in our understanding of the physiology of acid secretion and the gastric mucosal barrier. The other pivotal development in understanding these disorders has been the recognition of Helicobacter pylori's role in the pathophysiology of peptic ulcer disease,chronic gastritis, and even gastric malignancy. This evolution continues as H pylori wanes in significance, and medicine is challenged by treating iatrogenic conditions brought on by ulcerogenic anti-inflammatory drugs. Following a description of the relevant physiology and biochemistry of gastric acid secretion and the gastric mucosal barrier, this article describes the current medicinal arsenal available to treat acid-peptic disorders of the stomach.

    Helicobacter pylori is the main aetiologic factor for chronic gastritis worldwide. The degree of inflammation and the evolution of this form of chronic gastritis can vary largely depending on bacterial virulence factors, host susceptibility factors and environmental conditions. Autoimmune gastritis is another cause of chronic inflammation in the stomach, which can occur in all age groups. This disease presents typically with vitamin B12 deficiency and pernicious anaemia. The presence of anti-parietal cell antibodies is highly specific for the diagnosis. The role of H. pylori as a trigger for autoimmune gastritis remains uncertain. Other rare conditions for chronic gastritis are chronic inflammatory conditions such as Crohn's disease or on the background of lymphocytic or collagenous gastroenteropathies.

    The effects of Sulglycotide were evaluated in a pilot study of active H. pylori+ atrophic gastritis. Ten informed patients (mean age 51 +/- 13 years) entered a double-blind study. Five received Sulglycotide 400 mg three times a day for one year, the other 5, placebo. At 0, 30, 90, 270, and 360 days of treatment, patients underwent endoscopic examinations with multiple biopsies. Morphometric studies (number of inflammatory cells and percent gland volume), morphologic studies (according to the Sydney system), and flow cytofluorimetry were performed in all cases. Compared to findings in the placebo group, patients treated with Sulglycotide showed a reduced number of inflammatory cells and an increase in gland volume 120 days after treatment. While the difference was not statistically significant, the trend was confirmed by the morphologic patterns. Flow cytofluorimetry revealed an increase in the percentage of cells in the G2 phase (full maturation) and a parallel drop in the S phase (premitotic synthesis) in the Sulglycotide group only in the first three months. These data would appear to indicate an acceleration of gastric epithelial cell maturation and a decrease in the inflammatory infiltrate under the effect of Sulglycotide.

    Although previous studies have suggested an association between various gastrointestinal disorders and mood and anxiety disorders, no previous study has examined the relationship between a diagnosis of gastritis and mood and anxiety disorders in the community. This work aimed to investigate the association between physician-diagnosed gastritis and DSM-IV mood and anxiety disorders among adults in the general population, and to examine sex differences in these relationships. Data were drawn from a population-based, representative sample of 4181 adults aged 18-79 in the German National Health Interview and Examination Survey. Anxiety disorders (27.0% vs. 15.3%) and affective disorders (20.1% vs. 11.5%) were significantly more common among adults with compared to without a diagnosis of gastritis. Lifetime and current physician diagnosed gastritis were associated with an increased prevalence of panic attacks, social phobia, any mood disorder and major depression, compared to those without gastritis. There were no significant sex differences in these associations. A diagnosis of gastritis appears to be associated with significantly increased odds of mood and anxiety disorders among adults in the general population. Contrary to findings from animal studies, we found the relationship between gastritis and mood/anxiety consistent among both sexes.

    Adenosine deaminase (ADA), 5'-Nucleotidase (5NT), Xanthine oxidase (XO), Cu-Zn Superoxide dismutase (SOD) and Catalase (CAT) activities were determined in gastric juices from patients with gastric cancer, ulcer, gastritis and from healthy subjects. Enzyme activities were given as units per ml gastric juice and units per mg protein in gastric juice. ADA, 5NT and XO activities were found lower and protein concentrations were found higher in the cancer group than controls. There was however no significant difference between Cu-Zn SOD activities of the cancer and control groups. In all groups including control one, we could not find catalase activities in most of the samples. On the other hand, ADA, 5NT activities and protein concentrations in the gastric juice were lower in the gastritis group than control group. In the ulcer group, we found higher Cu-Zn SOD and XO activities and lower 5NT activity and protein concentrations compared with control values. In an attempt to establish statistical correlations between mean enzyme activities, pH and protein concentrations in the gastric juices of the groups, we found noticeable intra and inter-correlations, which indicated possible relations between DNA and free radical metabolizing enzymes.

    Gastric lipase is one of the prepancreatic lipases found in some mammalian species and in humans. Our knowledge of the hormonal regulation of gastric lipase secretion in children and adolescents is still very limited. The aim of this study was to compare the activity of human gastric lipase (HGL) in gastric juice in healthy adolescents and in patients with gastritis. The adolescents were allocated to three groups: the first including patients with Helicobacter pylori gastritis (HPG; n = 10), the second including patients with superficial gastritis caused by pathogens other than H. pylori (non-HPG; n = 14) and the control group including healthy adolescents (n = 14). Activity of HGL was measured in gastric juice collected during endoscopy. Plasma concentrations of cholecystokinin (CCK), glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic peptide (GIP) were measured in all adolescents. Activity of HGL in the non-HPG group was significantly lower than in the HPG group (p < 0.005) and the control group (p < 0.005). Mean plasma GIP levels in the control group were lower than in the non-HPG group (p < 0.003) and the HPG group (p < 0.01). We conclude that the regulation of HGL secretion by GLP-1 and CCK is altered in patients with gastritis. Moreover, GIP is a potent controller of HGL activity, both in healthy subjects and in patients with gastritis.

    Gastritis is a histopathologic diagnosis, which correlates poorly with both clinical symptoms of non-ulcer dyspepsia and endoscopic abnormalities. Worldwide, most cases of gastritis are due to Helicobacter pylori and are characterized by a diffuse superficial antral gastritis. Chronic inflammatory cells and lymphoid follicles are present in the lamina propria. Neutrophils are present in the surface and pit-lining epithelium. In North America and Western Europe, reactive gastropathy due to duodenal reflux or non-steroidal anti-inflammatory agents is also common. In this condition, there is no increase in inflammatory cells, but the pit-lining cells become hyperplastic, and the pits have a corkscrew appearance. Most examples of multifocal atrophic gastritis are the result of long standing Helicobacter gastritis, although there may be other causes as well. It is characterized by loss of glands in both pyloric and corpus mucosae with intestinal metaplasia of the surface epithelium. A subtype of intestinal metaplasia, in which sulphomucin (large bowel mucin) is present, has been associated with the development of distal gastric cancer. However, this association is relatively weak and is not considered useful for screening purposes. Gastric dysplasia may develop in areas of the stomach affected by intestinal metaplasia. High-grade dysplasia is a significant finding, with up to 60 percent of cases having coincident carcinoma and a further 25 percent of cases likely to develop an invasive malignancy within fifteen months.

    Alterations of the stomach mucosa in response to different adverse effects result in various morphological and clinical symptoms. Gastric mucosa alterations can be classified on the bases of diverse viewpoints. It makes this overview difficult, that identical toxic effects may cause different mucosal changes and different toxic agents may produce similar mucosal appearance. The more accurate understanding of the pathological processes which develop in the stomach mucosa needs reconsideration. The authors make an attempt to define gastritis and gastropathy in order to classify and present their features. Gastritis is a histological definition indicating mucosal inflammation. Acute gastritis is caused by infections. The two most important forms of chronic gastritis are metaplastic atrophic gastritis with an autoimmune origin and Helicobacter pylori inflammation. Gastropathy is the name of different structural alterations of the mucosa. Its most important feature is the paucity of inflammatory signs. Gastropathies can be divided into 4 categories based on the nature of the underlying pathological effect, on its morphological appearance and the way of the development. Differential diagnosis is an important pathological and clinical task because different treatment methods and prognosis.

    Peptic ulcer disease (PUD) has been reported to occur in children worldwide, but no information is available for our community. The aim of the study was to report our experience on the pattern of this condition in Saudi Arabian children. The records of all children below 18 years of age who were diagnosed by endoscopy to have PUD over a period of 10 years were analysed. From 1993 to 2002, 24 children out of 521(5 per cent) who presented with upper gastrointestinal tract (GIT) symptoms were diagnosed by endoscopy to have PUD. All but one (96 per cent) were Saudi nationals, the average age was 15 years (range 5-18 years), and the male to female ratio was 7:1. The commonest presentation was chronic abdominal pain in 15/24 (63 per cent) of the children, followed by vomiting associated with abdominal pain in four (17 per cent). Hematemesis and melena occurred in three (13 per cent), and two children (8 per cent), respectively. There were 20 duodenal (92 per cent) and four gastric ulcers. The primary type was the most common, occurring in 19 (79 per cent) of the children. Histopathology results of antral biopsies were available for 15 children; all of them had antral gastritis. Helicobacter pylori organisms were present in 13/15 (87 per cent) of the antral biopsy specimens. In Saudi children, peptic ulcer disease occurs more commonly in boys. It is a rare cause of upper GIT symptoms, but highly associated with H. pylori antral gastritis. This study documents a pattern similar to descriptions from other countries.

    Western countries are seeing a constant decline in the incidence of Helicobacter pylori-associated gastritis, coupled with a rising epidemiological and clinical impact of autoimmune gastritis. This latter gastropathy is due to autoimmune aggression targeting parietal cells through a complex interaction of auto-antibodies against the parietal cell proton pump and intrinsic factor, and sensitized T cells. Given the specific target of this aggression, autoimmune gastritis is typically restricted to the gastric corpus-fundus mucosa. In advanced cases, the oxyntic epithelia are replaced by atrophic (and metaplastic) mucosa, creating the phenotypic background in which both gastric neuroendocrine tumors and (intestinal-type) adenocarcinomas may develop. Despite improvements in our understanding of the phenotypic changes or cascades occurring in this autoimmune setting, no reliable biomarkers are available for identifying patients at higher risk of developing a gastric neoplasm. The standardization of autoimmune gastritis histology reports and classifications in diagnostic practice is a prerequisite for implementing definitive secondary prevention strategies based on multidisciplinary diagnostic approaches integrating endoscopy, serology, histology and molecular profiling.

    OBJECTIVES Recent studies using histology alone in select patients have suggested that Helicobacter pylori-negative gastritis may be common. The objective of this study was to investigate the prevalence of H. pylori among individuals with histologic gastritis. METHODS Subjects between 40 and 80 years underwent elective esophagogastroduodenoscopy at a VA Medical Center. Gastric biopsies were mapped from seven prespecified sites (two antrum, four corpus, and one cardia) and graded by two gastrointestinal pathologists, using the Updated Sydney System. H. pylori-negative required four criteria: negative triple staining at all seven gastric sites, negative H. pylori culture, negative IgG H. pylori serology, and no previous treatment for H. pylori. Data regarding tobacco smoking, alcohol drinking, nonsteroidal anti-inflammatory drug, and proton pump inhibitor (PPI) use were obtained by questionnaire. RESULTS Of the 491 individuals enrolled, 40.7% (200) had gastritis of at least grade 2 in at least one biopsy site or grade 1 in at least two sites. Forty-one (20.5%) had H. pylori-negative gastritis; most (30 or 73.2%) had chronic gastritis, five (12.2%) had active gastritis, and six (14.6%) had both. H. pylori-negative gastritis was approximately equally distributed in the antrum, corpus, and both antrum and corpus. Past and current PPI use was more frequent in H. pylori-negative vs. H. pylori-positive gastritis (68.2% and 53.8%; P = 0.06). CONCLUSIONS We used multiple methods to define non-H. pylori gastritis and found it in 21% of patients with histologic gastritis. While PPI use is a potential risk factor, the cause or implications of this entity are not known. PMID:23147524

    Peptic ulcer disease had a tremendous effect on morbidity and mortality until the last decades of the 20th century, when epidemiological trends started to point to an impressive fall in its incidence. Two important developments are associated with the decrease in rates of peptic ulcer disease: the discovery of effective and potent acid suppressants, and of Helicobacter pylori. With the discovery of H pylori infection, the causes, pathogenesis, and treatment of peptic ulcer disease have been rewritten. We focus on this revolution of understanding and management of peptic ulcer disease over the past 25 years. Despite substantial advances, this disease remains an important clinical problem, largely because of the increasingly widespread use of non-steroidal anti-inflammatory drugs (NSAIDs) and low-dose aspirin. We discuss the role of these agents in the causes of ulcer disease and therapeutic and preventive strategies for drug-induced ulcers. The rare but increasingly problematic H pylori-negative NSAID-negative ulcer is also examined.

    The isoprenoid pathway produces three key metabolites--endogenous digoxin-like factor (EDLF) (membrane sodium-potassium ATPase inhibitor and regulator of neurotransmitter transport), ubiquinone (free radical scavenger), and dolichol (regulator of glycoconjugate metabolism). The pathway was assessed in peptic ulcer and acid peptic disease and its relation to hemispheric dominance studied. The activity of HMG CoA reductase, serum levels of EDLF, magnesium, tryptophan catabolites, and tyrosine catabolites were measured in acid peptic disease, right hemispheric dominant, left hemispheric dominant, and bihemispheric dominant individuals. All the patients with peptic ulcer disease were right-handed/left hemispheric dominant by the dichotic listening test. The pathway was upregulated with increased EDLF synthesis in peptic ulcer disease (PUD). There was increase in tryptophan catabolites and reduction in tyrosine catabolites in these patients. The ubiquinone levels were low and free radical production increased. Dolichol and glycoconjugate levels were increased and lysosomal stability reduced in patients with acid peptic disease (APD). There was increase in cholesterol:phospholipid ratio with decreased glyco conjugate levels in membranes of patients with PUD. Acid peptic disease represents an elevated EDLF state which can modulate gastric acid secretion and the structure of the gastric mucous barrier. It can also lead to persistence of Helicobacter pylori infection. The biochemical pattern obtained in peptic ulcer disease is similar to those obtained in left-handed/right hemispheric chemically dominant individuals. But all the patients with peptic ulcer disease were right-handed/left hemispheric dominant by the dichotic listen ing test. Hemispheric chemical dominance has no correlation with handedness or the dichotic listening test. Peptic ulcer disease occurs in right hemispheric chemically dominant individuals and is a reflection of altered brain function.

    At present there is no universally accepted classification for gastritis. The first successful classification (The Sydney System) that is still commonly used by medical professionals was first introduced by Misiewicz et al in Sydney in 1990. In fact, it was the first detailed classification after the discovery of Helicobacter pylori by Warren and Marshall in 1982. In 1994, the Updated Sydney System was proposed during the International Workshop on the Histopathology of Gastritis followed by the publication in The American Journal of Surgical Pathology by Dixon et al. Using the new classification, distinction between atrophic and nonatrophic gastritis was revised, and the visual scale grading was incorporated. According to the Updated Sydney System Classification, atrophic gastritis is categorized into multifocal (H. pylori, environmental factors, specific diet) and corpus-predominant (autoimmune). Since metaplasia is a key histological characteristic in patients with atrophic gastritis, it has been recommended to use the word “metaplastic” in both variants of atrophic gastritis: autoimmune metaplastic atrophic gastritis (AMAG) and environmental metaplastic atrophic gastritis. Although there are many overlaps in the course of the disease and distinction between those two entities may be challenging, the aim of this review article was to describe the etiology, epidemiology, pathogenesis, diagnosis, clinical manifestations and treatment in patients with AMAG. However, it is important to mention that H. pylori is the most common etiologic factor for the development of gastritis in the world. PMID:28223833

    The aim of this study was to analyze the histological characteristics according to the updated Sydney classification (intensity of gastritis, degree of activity, gastric atrophy, intestinal metaplasia, and Helicobacter pylori) in symptomatic children referred for upper gastrointestinal endoscopy. A 4-year retrospective descriptive study was carried out in 619 children (282 females and 337 males), median age 3.75 years (15 days to 17.3 years) referred for endoscopy. Six gastric biopsies were done (three antrum and three corpus) for histological analysis (n = 4), direct examination and H. pylori culture (n = 2). H. pylori status was considered positive if at least two out of three tests were positive and negative if all three tests were negative. The results showed that only 66 children (10.66%) were H. pylori positive. Histological antral and corpus gastritis was detected in, respectively, 53.95% and 59.12% of all cases, most of them of mild grade 1. Antral and corpus activity was grade 1 in 18.57% and 20.03% of cases. H. pylori-positive versus H. pylori-negative children did differ in terms of moderate and marked histological gastritis and grade 2 or 3 activities. One girl had moderate gastric atrophy and another one moderate intestinal metaplasia, both being H. pylori negative. The findings indicate that primary antrum and corpus gastritis is 5.3 and 6.9 times, respectively, more frequent than H. pylori gastritis in French children, with usually mild histological gastritis and activity. Gastric atrophy and intestinal metaplasia are rare.

    Rheumatic diseases often have gastrointestinal(GI) manifestations, and may present as GI bleeding and perforation due to peptic ulcer associated with high mortality. Major causes of peptic ulcer related to rheumatic diseases are drugs such as nonsteroidal anti-inflammatory drug(NSAID) and corticosteroid, and vasculitis. The analgesic effects of NSAID often mask abdominal pain until they cause GI bleeding and perforation. Therefore, it is important to make early diagnosis of peptic ulcer with upper gastrointestinal endoscope. Fundamental treatment of NSAID induced peptic ulcer is to quit it, however it is difficult because of activity of rheumatic diseases. Also, most NSAID induced peptic ulcers heal by administration of proton pump inhibitor or misoprostol. Corticosteroid pulse therapy or administration of immunosuppressant agents is effective for vasculitis induced peptic ulcer, however it is difficult to make diagnosis of it. Development of NSAID with less side effects such as cyclooxygenase-2 selective inhibitors and establishment of diagnosis and treatment of peptic ulcer related to rheumatic diseases are expected.

    The discovery that Helicobacter pylori infection is the major cause of peptic ulcer disease revolutionised our views on the etiology and treatment of the disease. This discovery has tempted many experts to conclude that psychological factors and, specifically, stress are unimportant. However, Helicobacter pylori infection alone does not explain fully the incidence and prevalence of peptic ulcer disease. It has been demonstrated that stress can cause peptic ulcer disease even in the absence of Helicobacter pylori infection, supporting a multicausal model of peptic ulcer etiology. Psychological stress among other risk factors can function as a cofactor with Helicobacter pylori infection.

    Endoscopic findings of the background gastric mucosa are important in the Helicobacter pylori-seroprevalent population. It is strongly correlated not only with the risk of gastric cancer, but also with the excretion ability of gastric mucosa cells. In noninfected subjects, common endoscopic findings are regular arrangement of collecting venules, chronic superficial gastritis, and erosive gastritis. In cases of active H. pylori infection, nodularity on the antrum, hemorrhagic spots on the fundus, and thickened gastric folds are common endoscopic findings. The secreting ability of the gastric mucosa cells is usually intact in both noninfected and actively infected stomachs, and the intragastric condition becomes hyperacidic upon inflammation. Increased serum pepsinogen II concentration correlates well with active H. pylori infection, and also indicates an increased risk of diffuse-type gastric cancer. In chronic inactive H. pylori infection, metaplastic gastritis and atrophic gastritis extending from the antrum (closed-type chronic atrophic gastritis) toward the corpus (open-type chronic atrophic gastritis) are common endoscopic findings. The intragastric environment is hypoacidic and the risk of intestinal-type gastric cancer is increased in such conditions. Furthermore, there is a decrease in serum pepsinogen I concentration when the secreting ability of the gastric mucosa cells is damaged. Serologic and endoscopic changes that occur upon H. pylori infection are important findings for estimating the secreting ability of the gastric mucosa cells, and could be applied for the secondary prevention of gastric cancer.

    Over the past few decades, since the introduction of histamine H(2)-receptor antagonists, proton-pump inhibitors, cyclo-oxygenase-2-selective anti-inflammatory drugs (coxibs), and eradication of Helicobacter pylori infection, the incidence of peptic ulcer disease and ulcer complications has decreased. There has, however, been an increase in ulcer bleeding, especially in elderly patients. At present, there are several management issues that need to be solved: how to manage H. pylori infection when eradication failure rates are high; how best to prevent ulcers developing and recurring in nonsteroidal anti-inflammatory drug (NSAID) and aspirin users; and how to treat non-NSAID, non-H. pylori-associated peptic ulcers. Looking for H. pylori infection, the overt or surreptitious use of NSAIDs and/or aspirin, and the possibility of an acid hypersecretory state are important diagnostic considerations that determine the therapeutic approach. Combined treatment with antisecretory therapy and antibiotics for 1-2 weeks is the first-line choice for H. pylori eradication therapy. For patients at risk of developing an ulcer or ulcer complications, it is important to choose carefully which anti-inflammatory drugs, nonselective NSAIDs or coxibs to use, based on a risk assessment of the patient, especially if the high-risk patient also requires aspirin. Testing for and eradicating H. pylori infection in patients is recommended before starting NSAID therapy, and for those currently taking NSAIDs, when there is a history of ulcers or ulcer complications. Understanding the pathophysiology and best treatment strategies for non-NSAID, non-H. pylori-associated peptic ulcers presents a challenge.

    H. pylori infection is the main cause of peptic ulcer in children. Japan pediatric H. pylori research meeting made the guideline for diagnosis and eradication therapy for H. pylori. This guideline showed the methods for diagnose and the eradication therapy for children with H. pylori infection. Many pediatric patients have been free from some abdominal symptoms after eradication therapy for H. pylori. However we need endoscopy for diagnose in spite of children. And recently new non-invasive diagnostic devices are developed and some species acquired tolerance for clarithromycin. Therefore we hope that a new guideline for children will be written soon.

    Introduction Many clinicians consider chronic gastritis to be equivalent to Helicobacter pylori infection. However, it is known that there are numerous other causes of the condition. Aim Determination of the incidence of gastritis in patients with dyspepsia referred for diagnostic endoscopy of the upper part of the digestive tract, identification of the parts of the stomach most frequently affected by the inflammation, as well as the impact of an insufficient number of collected samples on the correct diagnosis. Material and methods Upper gastrointestinal endoscopy due to dyspepsia was performed in 110 patients. In the course of gastroscopy two biopsy specimens were collected for histopathological examination and towards H. pylori infection from the lesser and greater curvature in the antrum 3 cm from the pyloric sphincter, in the body – 4 cm proximally to the stomach angular incisure on the lesser curvature, and in the middle of the greater curvature, as well as in the subcardiac region on the side of the lesser and greater curvature. Results In patients with dyspepsia H. pylori-negative chronic gastritis is more common than gastritis with accompanying H. pylori infection. Collection of too small a number of biopsy specimens results in failure to detect inflammatory changes and/or H. pylori infection, which may be limited to one part of the stomach. Biopsy specimens of gastric mucosa should be collected in compliance with the assumptions of the Sydney System. Helicobacter pylori infection in people with dyspepsia is now being reported more rarely than in the past (36%). Conclusions In patients with dyspepsia chronic H. pylori-negative gastritis is more common than gastritis with an accompanying H. pylori infection. Helicobacter pylori infection is not always equivalent to the presence of chronic gastritis. PMID:28053685

    Peptic ulcer is one of the most prevalent diseases in gastrointestinal field. Recently, evolution was made for pathophysiology of peptic ulcer from "no acid, no ulcer" to Helicobacter pylori and non-steroidal anti-inflammatory drugs. The prevalence of peptic ulcer disease is estimated about 10% in Korea, and has declined due to Helicobacter pylori eradication therapy. Peptic ulcer has the cycle of exacerbation and improvement in the clinical course, and has not occasionally any clinical symptom. Helicobacter pylori eradication has made the marked reduction of relapse of peptic ulcer disease. Although nationwide endoscopic screening has enabled accurate diagnosis of peptic ulcer disease, general guideline for diagnosis of peptic ulcer has not made in Korea. Herein, we propose a guideline for the diagnosis of peptic ulcer according to domestic, international clinical studies, and experts opinions with level of evidence and grade of recommendation.

    AIM To investigate the roles of the neuropeptides vasoactive intestinal peptide (VIP), substance P (SP), and calcitonin gene-related peptide (CGRP) in chronic gastritis and duodenitis in children. METHODS Biopsy samples from the gastric and duodenal mucosa of 52 patients and 30 control subjects were obtained. Samples were taken for pathological examination, immunohistochemical staining, enzyme activity measurements and quantitative measurements of tissue peptide levels. RESULTS We observed differential effects of the disease on peptide levels, which were somewhat different from previously reported changes in chronic gastritis in adults. Specifically, SP was increased and CGRP and VIP were decreased in patients with gastritis. The changes were more prominent at sites where gastritis was severe, but significant changes were also observed in neighboring areas where gastritis was less severe. Furthermore, the degree of changes was correlated with the pathological grade of the disease. The expression of CD10, the enzyme primarily involved in SP hydrolysis, was also decreased in patients with duodenitis. CONCLUSION Based on these findings, we propose that decreased levels of VIP and CGRP and increased levels of SP contribute to pathological changes in gastric mucosa. Hence, new treatments targeting these molecules may have therapeutic and preventive effects. PMID:27729741

    Many clinicians believe hypercortisolism is ulcerogenic. However, data from clinical studies show that prophylaxis for peptic ulcer disease is no longer recommended in patients receiving corticosteroid treatment. This has not yet been verified in endogenous hypercortisolism by controlled clinical studies. The purpose of the current study was to evaluate the relationship between endogenous Cushing's syndrome (CS) and peptic ulcer disease and Helicobacter pylori infection. The study group contained 20 cases with CS resulting from ACTH-dependent endogenous hypercortisolism. The control groups consisted of 14 age- and gender-matched cases receiving exogenous corticosteroid therapy and 100 cases of dyspepsia with non-cushingoid features. Upper gastrointestinal endoscopy was performed on all cases. Biopsies were taken from five different points: two samples from the antrum, two samples from the corpus, and one sample from the fundus. A histological diagnosis of Helicobacter pylori infection was also obtained from evaluation of biopsy specimens. The frequency of stomach and duodenal ulcers did not vary between the groups (p = 0.5 and p = 0.7). Antral gastritis was less frequent and pangastritis was more common in cases with CS compared to the healthy controls (p = 0.001 and p < 0.001). The incidence of Candida esophagitis was more frequent in cases with CS compared to cases with corticosteroid treatment and healthy controls (p = 0.03). Histopathological findings and frequency of Helicobacter pylori based on pathology results did not vary between the three groups. It is possible that neither exogenous nor endogenous corticosteroid excess directly causes peptic ulcer or Helicobacter pylori infection. Prophylactic use of proton pump inhibitors is not compulsory for hypercortisolism of any type.

    Introduction Peptic ulcer is a lesion of the mucosal lining of the upper gastrointestinal tract characterized by an imbalance between aggressive and protective factors of the mucosa, having H. pylori as the main etiologic factor. Dietotherapy is important in the prevention and treatment of this disease. Aim To update nutritional therapy in adults' peptic ulcer. Methods Exploratory review without restrictions with primary sources indexed in Scielo, PubMed, Medline, ISI, and Scopus databases. Results Dietotherapy, as well as caloric distribution, should be adjusted to the patient's needs aiming to normalize the nutritional status and promote healing. Recommended nutrients can be different in the acute phase and in the recovery phase, and there is a greater need of protein and some micronutrients, such as vitamin A, zinc, selenium, and vitamin C in the recovery phase. In addition, some studies have shown that vitamin C has a beneficial effect in eradication of H. pylori. Fibers and probiotics also play a important role in the treatment of peptic ulcer, because they reduce the side effects of antibiotics and help reduce treatment time. Conclusion A balanced diet is vital in the treatment of peptic ulcer, once food can prevent, treat or even alleviate the symptoms involving this pathology. However, there are few papers that innovate dietotherapy; so additional studies addressing more specifically the dietotherapy for treatment of peptic ulcer are necessary. PMID:25626944

    One hundred and two patients suffering from giardiasis and/or chronic gastritis were subjected for upper gastrointestinal endoscopy. Purified immune rabbit's serum against Giardia lamblia was used in ELISA and immunoperoxidase (IIP) techniques for detection of Giardia antigen in the stomach. Results showed that out of 70 cases with intestinal giardiasis, 8 (11.4%) by ELISA and 6 (8.6%) by IIP showed gastric giardiasis. Higher percentage of gastric giardiasis (14%) was encountered in cases with both giardiasis and chronic gastritis (50) than in cases with giardiasis alone (5%) but with statistically insignificant difference (P > 0.05). None of the cases with chronic gastritis alone (without giardiasis) was positive for gastric giardiasis. Dyspepsia was the main presenting symptom in cases with gastric giardiasis (P < 0.05) with significant (P < 0.05) association. Helicobacter pylori was encountered in 6 out of 8 cases (75%) with gastric giardiasis (P < 0.05) with significant (P < 0.05) association. Duodenogastric reflux was detected in 4 out of 8 cases (50%). Histopathological changes in antral mucosa were detected in all cases of gastric giardiasis. This study indicates that under abnormal circumstances most probably with decreased gastric acidity, gastric giardiasis can occur in concomitance with intestinal giardiasis. So, one has to search for Giardia in gastric biopsies, particularly those showing chronic atrophic gastritis and H. pylori. Also, one has to be aware of gastric giardiasis as a possible cause of upper gastrointestinal symptoms.

    A peptic ulcer in a child looks the same as it does in an adult, and many of the aetiologies of peptic ulcer disease in children are similar to those in adults. However, there are many differences between children and adults, especially in the areas of clinical presentation, the prevalences of different types of ulcer disease, and the prevalence of complications of ulcer disease. Therefore the approach to diagnosis and management in children is often at variance with that in adults. One important example is the approach to suspected Helicobacter pylori (H. pylori) disease in children, in which consensus groups have advised a considerably different approach in children. While the chapter deals with the full range of peptic ulcer disease in children, the focus is on those aspects in which there are differences between adults and children.

    Ulceration corresponds to tissue loss, breaching the muscularis mucosae. When ulcers develop in the acid-peptic environment of the gastroduodenum, they are traditionally called peptic ulcer (PUD). Ulcers never develop spontaneously in a healthy gastroduodenal mucosa. Ulceration is the ultimate consequence of a disequilibrium between aggressive injurious factors and defensive mucosa-protective factors. The dominant aggressors are strong acid and high proteolytic (pepsin) activity in gastric secretions. The dominant defensors are the phospholipid surfactant layer, covering the mucus bicarbonate gel, the mucus bicarbonate layer covering the epithelium, the tight junctional structures between the epithelial cells, restricting proton permeability, and the epithelial trefoil peptides, contributing to healing after injury. Initially, acid-peptic aggression was considered the overwhelming cause of PUD, supported by the pioneering work of Schwartz, launching the dictum 'no acid, no ulcer'. This led to the universal therapy directed against intragastric acidity, also interfering with peptic activity when the pH was >4. The therapeutic sequence went from large doses of antacids to H(2)-receptor antagonists and finally to proton pump inhibitors (PPIs). The longer the intragastric pH was >3, the quicker ulcer healing was seen. Unfortunately, ulcers often recurred after stopping therapy, demanding maintenance therapy to keep the ulcers healed and to prevent the need for surgery (vagotomy, partial gastric resection). Later on, the emphasis gradually shifted to weakening/failing of the defensive factors, raising the vulnerability of the gastroduodenal mucosa to luminal secretions. Leading injurious mechanisms jeopardizing the mucosal integrity are numerous: infections, especially Helicobacter pylori, drug-induced injury, particularly acetylsalicylic acid (ASA) and non-steroidal anti-inflammatory drugs (NSAIDs), physicochemical and caustic injury, vascular disorders, interfering

    This study analyzes data on peptic ulcer disease based on deaths for 1951-1988 and hospital separations for 1969-1988. The source of the data are mortality and morbidity statistics provided to Statistics Canada by the provinces. The age-standardized mortality rates (ASMR) for peptic ulcer disease decreased from 1951 to 1988 by 69.4% for men (8.5 to 2.6 per 100,000 population), and 31.8% for women (2.2 to 1.5). Separation rates from hospitals during 1969-1988 for peptic ulcer disease also decreased by 59.8% for men (242.7 to 97.6 per 100,000 population) and 35.6% for women (103.2 to 66.5). Age-specific rates for both mortality and hospital separations increased with age. Epidemiological studies indicate that the incidence of peptic ulcer disease is declining in the general population. The downward trends in mortality and hospitalization rates for peptic ulcer disease reflect this change in incidence, but additional factors probably contribute as well to this decline. Male rates for both mortality and hospital separations were much higher than female rates at the beginning of the study period; but toward the end, the gap between the sexes narrowed considerably, mainly because the male rates declined substantially while the female rates decline moderately. The slower decline in the rates for women may be related to such factors as the increasing labour force participation among women and the slower decline in the population of female smokers.

    Emphysematous gastritis is a rare form of gastritis caused by infection of the stomach wall by gas forming bacteria. It is a very rare condition that carries a high mortality rate. Portal venous gas shadow represents elevation of intestinal luminal pressure which manifests as emphysematous gastritis or gastric emphysema. Literature reviews show that the mortality rate is especially high when portal venous gas shadow is present on CT scan. Until recently, the treatment of emphysematous gastritis has been immediate surgical intervention. However, there is a recent trend of avoiding surgery because of the frequent occurrence of post-operative complications such as anastomosis leakage. In addition, aggressive surgical treatment has failed to show significant improvement in prognosis. Recently, the authors experienced a case of emphysematous gastritis accompanied by portal venous gas which was treated successfully by conservative treatment without immediate surgical intervention. Herein, we present a case of emphysematous gastritis with concomitant portal venous air along with literature review.

    The frequency of gastric Crohn's disease has been considered low. This study was undertaken to determine the prevalence of chronic gastritis and Helicobacter pylori infection in patients with Crohn's disease. Oesophagogastroduodenoscopy was performed on 62 consecutive patients suffering from ileocolonic Crohn's disease. Biopsy specimens from the antrum and corpus were processed for both histological and bacteriological examinations. H pylori antibodies of IgG and IgA classes were measured in serum samples by enzyme immunoassay. Six patients (9.7%) were infected with H pylori, as shown by histology, and in five of them the infection was also verified by serology. Twenty one patients (32%) had chronic H pylori negative gastritis (negative by both histology and serology) and one of them also had atrophy in the antrum and corpus. Granulomas were found in four patients. The characteristic appearance of H pylori negative gastritis was focal and mostly mild inflammation resembling the inflammatory changes seen in the gut in Crohn's disease. Patients with H pylori negative chronic gastritis had a significantly more active disease in their gut than those with normal gastric mucosa (p < 0.01). It is concluded that H pylori positive gastritis is rare, while H pylori negative gastritis is relatively common in patients with Crohn's disease. H pylori negative 'Crohn's gastritis' seems to be associated with active Crohn's disease. Images Figure 1 Figure 2 PMID:8675090

    To summarize the current views and insights on associations between Helicobacter pylori (H. pylori)-related chronic gastritis and colorectal neoplasm, we reviewed recent studies to clarify whether H. pylori infection/H. pylori-related chronic gastritis is associated with an elevated risk of colorectal neoplasm. Recent studies based on large databases with careful control for confounding variables have clearly demonstrated an increased risk of colorectal neoplasm associated with H. pylori infection. The correlation between H. pylori-related chronic atrophic gastritis (CAG) and colorectal neoplasm has only been examined in a limited number of studies. A recent large study using a national histopathological database, and our study based on the stage of H. pylori-related chronic gastritis as determined by serum levels of H. pylori antibody titer and pepsinogen, indicated that H. pylori-related CAG confers an increased risk of colorectal neoplasm, and more extensive atrophic gastritis will probably be associated with even higher risk of neoplasm. In addition, our study suggested that the activity of H. pylori-related chronic gastritis is correlated with colorectal neoplasm risk. H. pylori-related chronic gastritis could be involved in an increased risk of colorectal neoplasm that appears to be enhanced by the progression of gastric atrophy and the presence of active inflammation.

    GERD and peptic ulcer disease are important diseases in the elderly. GERD presents similarly in the elderly and the young, although elderly patients may have less severe symptoms yet more severe mucosal disease and a higher prevalence of BE. Although the prevalence of H. pylori is falling, the elderly remain at risk for peptic ulcer because of the widespread use of NSAIDS. The presentation of peptic ulcer disease in the elderly can be subtle and atypical when compared with younger patients, leading to a delay in diagnosis. Because of comorbidity in the aged, peptic ulcer disease and its complications result in increased morbidity and mortality rates.

    The gastric duodenal mucosa normally is protected from the damaging effects of gastric acid and pepsin by ill-defined mechanisms. Ulcers may arise when there is an imbalance between the aggressive and defensive factors that renders the mucosa susceptible to damage. A variety of factors have been identified that may favor the development of peptic ulcers, but no single pathophysiologic defect applies in all ulcer patients. In duodenal ulcers, gastric acid hypersecretion is observed in as many as one third of patients; however, most patients with duodenal ulcers secrete normal amounts of gastric acid. Decreased mucosal bicarbonate secretion may be important in at least some duodenal ulcer patients. Use of NSAIDs may cause either gastric or duodenal ulcers, probably through the inhibition of mucosal prostaglandin synthesis and disruption of mucosal defenses. Finally, a recently identified bacterium, H. pylori, causes a chronic gastritis that is found in the overwhelming majority of patients with duodenal ulcers and non-NSAID-associated gastric ulcers. This bacterium may play a pivotal role in ulcer pathogenesis and, especially, in ulcer recurrences. A number of drugs of proved efficacy are available for the treatment of acute duodenal and gastric ulcers. The H2 receptor antagonists administered once daily remain the mainstay of ulcer therapy because of their efficacy, ease of use, and excellent safety profile. More thorough and long-lasting acid inhibition is afforded by the H+/K(+)-ATPase inhibitor omeprazole. This agent also promotes more rapid ulcer healing, but in most patients, this minor advantage may not justify the higher cost. It is not known whether more rapid healing will translate into lower ulcer complication rates. Until further data are available, this drug may be preferable in patients with large or complicated ulcers. In patients with refractory ulcers, omeprazole is clearly superior to other available agents. Agents that promote mucosal defense

Various factors such as pepsin, gastric acid, H. pylori, NSAIDs, prostaglandins, mucus, bicarbonate, and blood flow to mucosa play an important role in causing peptic ulcers. In this review article, our main focus is on some important gastroretentive drug delivery systems (GRDDS) (floating, bioadhesive, high density, swellable, raft forming, superporous hydrogel, and magnetic systems) which will be helpful in gastroretention of different dosage forms for treatment of peptic ulcer. GRDDS provides a mean for controlled release of compounds that are absorbed by active transport in the upper intestine. It also enables controlled delivery for paracellularly absorbed drugs without a decrease in bioavailability. The above approaches are specific for targeting and leading to a marked improvement in the quality of life for a large number of patients. In the future, it is expected that they will become of growing significance, finally leading to improved efficiencies of various types of pharmacotherapies.

    Global genome hypomethylation as an epigenetic phenomenon may induce (pre)neoplastic transformation through inducing chromosomal and genomic instability and activating oncogenes. Global genome hypomethylation has a fundamental role in early stages of tumorigenesis but little is known about this epigenetic event in gastric precancerous lesions such as gastritis. Therefore, we decided to evaluate this issue in gastritis lesion for obtaining new insight toward molecular biology of gastric cancer. Here we used a technique composed of restriction enzyme digestion and pyrosequencing known as luminometric methylation assay to evaluate this issue. DNA obtained from normal and gastritis lesions was digested with HpaII (sensitive to methylation in its cut site) and MspI (insensitive). Overhangs resulting from these enzymes then fill in by polymerase extension assay using pyrosequencing instrument. Nucleotide incorporation during polymerase extension generates light, which expresses as pick in the pyrogram. By comparing the height of picks obtained form both enzymes it can be possible to evaluate and compare global genome methylation level of gastritis and normal tissues. If the target site is fully methylated, the HpaII/MspI (their pick height) will approach zero. If not, this ratio will be around 1. In the other conditions this ratio varies between 0 and 1. Comparing the ratio of normal and gastritis sample, it can be inferred whether or not gastritis is hypomethylated. This study was performed on 83 gastritis and normal adjacent tissues. The patients included 34 male and 49 female and were 15 to 83 years old. According to our study, gastritis tissue was hypomethylated more than the normal tissue (p = 0.028). Global genome methylation has no significant correlation with MSI, pathological findings, age, and gender. We conclude that global genome hypomethylation occurs in the gastritis level. This reduction probably continues in the next steps toward gastric cancer and may

    The varicella zoster virus (VZV) is a very rare cause of gastritis. Gastritis caused by VZV can be presented as abdominal pain, vomiting. Most of the cases reported with varicella gastritis in the literature are immunocompromised patients with various kinds of malignancy, and most of these patients are adults. Here we report an adolescent girl with acute abdominal pain. The girl was immunocompetent. Her endoscopically taken biopsy material revealed varicella, and her gastritis was healed with acyclovir therapy. This is a very rare condition and not frequently reported in the literature. The authors want to drive attention to the fact that varicella gastritis can be seen in immunocompetent children, the presentation can be nausea, vomiting and/or (severe) abdominal pain. Serological studies may be less helpful than tissue studies, so interventional procedures should be done.

    Although autoimmune atrophic gastritis is classically a disease of elderly adults, recent studies have described the disease in younger adults, particularly in those with other autoimmune diseases and iron-deficiency anemia. Atrophic gastritis in pediatrics is a rare and possibly underdiagnosed entity that has been primarily reported as single-case reports. This retrospective study of atrophic gastritis not associated with Helicobacter pylori infection was performed to further expand the knowledge of clinical presentation, pathologic findings, and natural history of this disease in the pediatric population. Twelve patients with a histologic diagnosis of atrophic gastritis were identified, with an age range of 8 months to 18 years. Seven had other autoimmune diseases and/or immunodeficiency. Atrophy was confined to the oxyntic mucosa in 10 patients, with intramucosal inflammation in a diffuse or basal-predominant pattern. Active inflammation was present in 7 patients. Pseudopyloric, intestinal, or squamous/mucinous metaplasia was seen at initial biopsy or on follow-up in 8 patients, and enterochromaffin-like cell hyperplasia was seen in 5. One patient developed an adenocarcinoma during the follow-up period of 10 years. Two false-negative diagnoses were retrospectively identified. In the majority of cases, the possibility of atrophic gastritis was not raised by the submitting physician, and the endoscopic findings were not specific. Therefore, accurate diagnosis requires a high degree of suspicion on the part of the pathologist, and the diagnosis should be considered particularly in patients with a clinical history of other autoimmune diseases or iron-deficiency anemia.

  18. Role of dietary polyphenols in the management of peptic ulcer.

    Peptic ulcer disease is a multifactorial and complex disease involving gastric and duodenal ulcers. Despite medical advances, the management of peptic ulcer and its complications remains a challenge, with high morbidity and death rates for the disease. An accumulating body of evidence suggests that, among a broad reach of natural molecules, dietary polyphenols with multiple biological mechanisms of action play a pivotal part in the management of gastric and duodenal ulcers. The current review confirmed that dietary polyphenols possess protective and therapeutic potential in peptic ulcer mediated by: improving cytoprotection, re-epithelialization, neovascularization, and angiogenesis; up-regulating tissue growth factors and prostaglandins; down-regulating anti-angiogenic factors; enhancing endothelial nitric oxide synthase-derived NO; suppressing oxidative mucosal damage; amplifying antioxidant performance, antacid, and anti-secretory activity; increasing endogenous mucosal defensive agents; and blocking Helicobacter pylori colonization associated gastric morphological changes and gastroduodenal inflammation and ulceration. In addition, anti-inflammatory activity due to down-regulation of proinflammatory cytokines and cellular and intercellular adhesion agents, suppressing leukocyte-endothelium interaction, inhibiting nuclear signaling pathways of inflammatory process, and modulating intracellular transduction and transcription pathways have key roles in the anti-ulcer action of dietary polyphenols. In conclusion, administration of a significant amount of dietary polyphenols in the human diet or as part of dietary supplementation along with conventional treatment can result in perfect security and treatment of peptic ulcer. Further well-designed preclinical and clinical tests are recommended in order to recognize higher levels of evidence for the confirmation of bioefficacy and safety of dietary polyphenols in the management of peptic ulcer.

    A 56 year-old male patient had a gastric resection (Billroth II) at age 33. In 1993 he had vague upper digestive complaints. During investigations for a moderate anaemia biopsies performed during an oesogastroduodenoscopy revealed a jejunitis with Giardia lamblia (G.l.) trophozoites which were also found on the gastric mucosa associated with Helicobacter pylori related chronic active gastritis. The few publications dealing with the presence of Giardia lamblia in the stomach either assert or cast some doubts on the pathogenicity of this protozoa for the gastric mucosa. Gastric involvement by G.l. is usually associated with duodeno-jejunal disease responsible for diarrhoea which may occur as epidemics of varying extension. Since Giardia lamblia infection is not submitted to reporting in Switzerland, the epidemiology in our country is scarcely known and investigated. In our opinion, however, health authorities in Switzerland should consider the need of reporting this infectious disease.

    The bacterium Helicobacter pylori is one of the main causes of peptic ulcers. But how was this causal relationship demonstrated? A historical and philosophical analysis of a series of studies conducted during the 1980s can elucidate the question. In the beginning, a mere correlation between the newly discovered bacterium and peptic ulcers was found in gastric biopsies. It remained an open question whether the bacterium caused the disease, or whether it constituted merely an opportunistic infection. Yet determining the direction of causality was difficult in the absence of an animal model: Even though gastritis was observed in a courageous self-experiment involving a swallowed bacterial culture, tf!e significance of the individual case was small. The failings of the self-experiment could only be rectified by a randomised, placebo-controlled trial which met the requirements of Koch's third postulate. Moreover, it was necessary to gain an initial understanding of the mechanism by which the causal relationship between H. pylori and peptic ulcers is mediated: How, forexample, does the bacterium survive in the acid environment of the stomach? The study of the case from the perspective of the history and philosophy of science illustrates how medical knowledge is established incrementally.

    Helicobacter pylori colonizes the human gastric epithelium and causes diseases such as gastritis, peptic ulcers, and stomach cancer. Undecaprenyl pyrophosphate synthase (UPPS), which catalyzes consecutive condensation reactions of farnesyl pyrophosphate with eight isopentenyl pyrophosphate to form lipid carrier for bacterial peptidoglycan biosynthesis, represents a potential target for developing new antibiotics. In this study, we solved the crystal structure of H. pylori UPPS and performed virtual screening of inhibitors from a library of 58,635 compounds. Two hits were found to exhibit differential activities against Helicobacter pylori and Escherichia coli UPPS, giving the possibility of developing antibiotics specially targeting pathogenic H. pylori without killing the intestinal E. coli.

    Helicobacter pylori causes various diseases such as chronic gastritis, peptic ulcer and gastric cancer. While majority of the people infected with H. pylori is asymptomatic, 15-20 % of them develop such diseases. The main factors, which determine the development of H. pylori related diseases might be bacterial virulence, host genetic and environmental factors.The aim of this study was to reveal the factors that play a role in the disease development in patients with reflux esophagitis and peptic ulcer, infected with Helicobacter pylori. Environmental factors such as medical agents, smoking and body mass index were evaluated. The factors specific to bacteria such as vacA, CagA, babA and iceA virulence genotypes and the host factors such as IL-1, IL-2, IL-4, IL-6, IL-10, IL-12, interferon-γ, TNF-α, ve TGF-β1 gene polymorphisms were compared between the two groups.H. pylori infected twenty five patients with reflux esophagitis and peptic ulcer were enrolled in the study. There was no statistical difference between the two groups regarding environmental factors. IL-2 -330T +166T (p=0.037) and IL10 -1082A; -819C (p=0.049) gene polymorphisms were significantly more common in the group of patients with peptic ulcer compared to the group with reflux esophagitis. In both groups of patients, either with reflux esophagitis or peptic ulcer, multiple H. pylori virulence genotypes (cagA, vacA, babA) (mean values 74 %, 78 %, 54 % respectively) were observed.In this study, we revealed that cytokine gene polymorphisms may play a role in the development peptic ulcer while H. pylori virulence genotypes seem to be crucial for the development of associated diseases (Tab. 4, Ref. 51).

    AIMS--To determine the prevalence of lymphoid follicles in Helicobacter pylori positive and negative gastritis in antral and body type gastric mucosa in patients with non-ulcer dyspepsia (NUD), duodenal ulcer, or gastric ulcer; to correlate follicle presence with patient age; to evaluate the correlation between the prevalence of lymphoid follicles and active and inactive gastritis and its severity; and to assess the positive predictive value of lymphoid follicle prevalence with respect to H pylori infection. METHODS--Gastric biopsy specimens, graded according to the Sydney system, from 337 patients were studied. RESULTS--Lymphoid follicles occurred more often in antral mucosa (78%) than in body type mucosa (41%) and were observed in 85% of patients with H pylori positive gastritis. There was no significant difference between NUD and gastric and duodenal ulcer disease with regard to the presence of lymphoid follicles. The positive predictive value of the presence of lymphoid follicles in H pylori infection was 96%. Lymphoid follicles were more commonly observed in patients aged between 10 and 29 years. Lymphoid follicles were more frequently found in pangastritis of all subtypes than in antral gastritis and also in active gastritis than in inactive gastritis. The presence of lymphoid follicles correlated strongly with the degree and severity of gastritis. CONCLUSION--Lymphoid follicles are a constant morphological feature of H pylori associated gastritis.

    Four cases of peptic ulcer penetrating the head of the pancreas were diagnosed by computed tomography (CT). Findings common to 3 cases included (a) an ulcer crater, (b) a sinus tract, and (c) enlargement of the head of the pancreas. Unlike other modalities, the inherent spatial resolution of CT allows a convenient diagnosis of this important complication of peptic ulcer disease.

    The aim of this study was to observe the histological features of chronic gastritis and associated effects due to Helicobacter pylori infection in 176 randomly selected antral biopsy specimens of chronic gastritis cases. The specimens were reviewed for the presence or absence of H.pylori. The activity (neutrophilic infiltration) of gastritis and the presence or absence of mucosa-associated lymphoid tissue (MALT) were also noted. Chi-square test (Pearson value) was used to analyze categorical variables. H.pylori was detected in 110 (62.5%) cases of chronic gastritis. There was a significant association between H.pylori infection and activity of chronic gastritis (p=0.002). Lymphoid aggregates were significantly more frequently noted in H.pylori-positive patients (68.2%) vs. H.pylori negative group (47%), (p=0.005). It is concluded that H.pylori is significantly associated with active chronic gastritis and with formation of mucosa-associated lymphoid tissue (MALT), which may develop into gastric lymphoma (MALT type).

    The aim of this study was to identify the species and determine the prevalence of gastric Helicobacter in the saliva of dogs with gastritis. The study was carried out on 30 dogs of different breeds, genders and ages, which were diagnosed with gastritis. The nested-PCR method was used to detect Helicobacter spp. in saliva. Helicobacter bacteria were found in the saliva samples of 23 (76.6%) dogs. Helicobacter heilmannii was the most commonly detected species of gastric Helicobacter spp. in canine saliva, and was found in 22 (73.3%) cases. The results indicate that gastric Helicobacter spp. occurs relatively frequently in dogs with gastritis. Moreover, the saliva of dogs with gastritis may be a source of Helicobacter spp. infection for humans and other animals. However, further studies are needed to confirm this finding as the PCR method does not distinguish active from inactive infections.

    Authors in this article present etiology, clinical manifestations, diagnostic procedures and treatment of peptic ulcer disease in children and adults. Increased gastric acid output, Helicobacter pylori, NSAIDs and stress are the basic risk factors in peptic ulcer disease. H. pylori infection is a widely known risk factor in peptic ulcer disease and influences diagnostic and treatment procedures. Primary ulcer disease concerns mainly duodenum and is accompanied by H. pylori infection. Gastroscopy and Helicobacter tests are the only reliable procedures to diagnose peptic ulcer disease. Nowadays the most important aim in peptic ulcer treatment is the H. pylori eradication. Therapy with two antibiotics and a protein pomp inhibitor eradicates the bacteria, treats the ulceration and lowers the number of ulcer recurrence. In non-infected H. pylori ulcers or in a long-term treatment protein pomp inhibitors and H2-inhibitors are effective as well in gastroprotective therapy.

    Our main objective was to study gastritis associated to duodeno-gastric reflux. It is about a longitudinal study case/witness, paired according to the sex and the age. It was unrolled from February 2005 to January 2006 in the digestive diseases department of the hospital Gabriél Touré, and endoscopic centers of Promenade des Angevins, and clinique Farako. The patients profited from an upper digestive endoscopy to appreciate endoscopic aspect of gastritis associated to bile in the stomach mucus lake. The gastric biopsies were systematic. This study included 50 patients having gastritis associated to bile in gastric mucus lake compared to 50 patients having gastritis associated to clearly gastric mucus lake. The sex-ratio was 1.26 in favour of men. The average age of the patients was of 41.30 +/- 15.43 years. On the symptomatic hand, fetid breath was significantly met in duodeno-gastric reflux (p = 0.013). Potash consumption in the "tô" (millet cake) was significantly reported in gastritis associated to bile in gastric mucus lake (p = 0.042). The endoscopic aspects were comparable. Histological aspects of nonatrophic chronic gastritis were significantly mint in witnesses as well into the antrum as into the fundus (p = 0.0001 and p = 0.00023). The reactional gastritis aspect was the prerogative of duodenogastric reflux (p ranging between 10(-6) and 3.10 (-6). Helicobacter pylori infection was found comparable in the two groups (p = 0.297). Dysplasia although rare was found only in gastritis associated to duodeno-gastric reflux. Gastritis associated to bile in gastric mucus does not se,nm to have specific clinical, endoscopic and histological presentation. However the presence of dysplasia must have an attentive monitoring.

To examine the short- and long-term mortality in PUB compared to a matched control group including identification of predictive factors for adverse outcome, identification of underlying causes of death, and investigation of a possible association between treatment with blood transfusion and long-term mortality (Study III). Study I was conducted as a prospective validation study. During a two-year period 831 patients presenting with upper gastrointestinal haemorrhage were included. The study demonstrated that the Glasgow Blatchford Score (GBS) was superior to the other risk scoring systems at predicting need for hospital-based intervention. The GBS was found to be favourable for the assessment of Danish patients presenting with symptoms of upper gastrointestinal haemorrhage. According to the findings of Study 1 implementation of the GBS at a 1000-bed hospital would be associated with a 90.000 EUR annual saving through avoidance of admission of patients in very low risk of needing hospital-based intervention. None of the examined risk scoring systems were suitable for predicting risk of rebleeding or 30-day mortality. Study II was designed as a non-blinded, stratified, parallel group, randomized controlled trial. Patients were randomized in a 1:1 ratio to receive STAE within 24 hours from therapeutic endoscopy or to continue standard treatment. A total of 105 patients were included. After adjustment for possible imbalances STAE was associated with a clear trend of reduced rate of rebleeding (P=.079). Numbers needed to treat in order to avoid one case of rebleeding was 10.

    Helicobacter pylori (H. pylori) colonization induces vigorous innate and specific immune responses; however, the infection is not removed, a state of chronic active gastritis persists for life if untreated. Recent studies have shown that CD4(+) CD25(+) Foxp3-positive regulatory T cells (Tregs) suppress the immune response to H. pylori. Persistent H. pylori-associated gastritis is closely associated with gastric carcinogenesis. We investigated the number of Tregs in the context of H. pylori colonization in chronic gastritis, examined the relationship between it and histopathological findings and compared it with that of gastric dysplasia and adenocarcinoma. This study was based on the analysis of gastric biopsy specimens from 126 cases of H. pylori-associated gastritis, 16 cases of H. pylori-negative gastritis, 17 cases of gastric dysplasia, and 25 cases of gastric adenocarcinoma. The number of Tregs was elevated in H. pylori-associated gastritis, where it was positively correlated with the grade of chronic inflammation and the number of lymphoid follicles. It was significantly elevated in adenocarcinomas compared to chronic gastritis and gastric dysplasia. In summary, the number of Tregs is increased in H. pylori-associated gastritis and gastric cancer.

    Peptic ulcer and gastroesophageal reflux are common acid-peptic related diseases. The pathophysiology of peptic ulcer disease has been centered on an imbalance between aggressive and defensive factors. This study was conducted to examine whether the combined use of omeprazole (CAS 73590-58-6), a proton pump inhibitor, and DA-9601, a novel anti-ulcer formulation of the extract of Artemisia asiatica Nakai, has synergistic effects on various peptic ulcers and gastroesophageal reflux diseases in animal models. An optimal combination ratio of omeprazole and DA-9601 was investigated in an acetic acid-induced ulcer model. In the results, oral pretreatment with omeprazole and DA-9601 (combination ratio, 1:3) significantly reduced alcohol-, indometacin-, acetic acid-, and cysteamine-induced gastrointestinal lesions in a synergistical manner in rats. The combination treatment also significantly attenuated the gross and histopathological lesions in an experimental reflux esophagitis model as compared to the single treatment of omeprazole or DA-9601. In an alcohol-induced gastritis model, the combined treatment resulted in a significant decrease in lipid peroxidation with concomitant increases in glutathione content and prostaglandin E2 level, which was proportional to the inhibitory effect of the combination therapy. These results suggest that the combined therapy with omeprazole and DA-9601, a cytoprotectant, can be beneficial for the treatment of peptic ulcer and reflux esophagitis.

    Peptic ulcer disease (PUD) affects 4 million people worldwide annually. The incidence of PUD has been estimated at around 1.5% to 3%. Perforated peptic ulcer (PPU) is a serious complication of PUD and patients with PPU often present with acute abdomen that carries high risk for morbidity and mortality. The lifetime prevalence of perforation in patients with PUD is about 5%. PPU carries a mortality ranging from 1.3% to 20%. Thirty-day mortality rate reaching 20% and 90-d mortality rate of up to 30% have been reported. In this review we have summarized the current evidence on PPU to update readers. This literature review includes the most updated information such as common causes, clinical features, diagnostic methods, non-operative and operative management, post-operative complications and different scoring systems of PPU. With the advancement of medical technology, PUD can now be treated with medications instead of elective surgery. The classic triad of sudden onset of abdominal pain, tachycardia and abdominal rigidity is the hallmark of PPU. Erect chest radiograph may miss 15% of cases with air under the diaphragm in patients with bowel perforation. Early diagnosis, prompt resuscitation and urgent surgical intervention are essential to improve outcomes. Exploratory laparotomy and omental patch repair remains the gold standard. Laparoscopic surgery should be considered when expertise is available. Gastrectomy is recommended in patients with large or malignant ulcer. PMID:28138363

    Helicobacter pylori (H. pylori) has been presumed to be an initiating factor in a previously recognized chain of events, starting with active chronic gastritis and leading to atrophy of the mucosal membrane, intestinal metaplasia, dysplasia (intraepithelial neoplasia), and finally culminating in gastric carcinoma. Adherence of H. pylori to the gastroduodenal epithelium is believed to be an important step in the induction of active chronic inflammation of the mucosal layer. However, it is not clear how the pathogen chronically colonizes the gastroduodenal epithelium. In this study, 30 biopsy specimens from H. pylori-positive peptic ulcer (15 for gastric ulcer, 15 for duodenal ulcer) patients were examined by transmission electron microscopy (TEM) to observe the structural adherence of H. pylori to gastroduodenal epithelium while ten healthy postulants were served as controls. We also investigated the interaction between H. pylori and gastroduodenal epithelial cells. Morphological appearances of both the pathogen and the cells as well as features of colonization, attachment, and internalization were observed. H. pylori exhibited both spiral and coccoid forms. Cytoplasmic vacuolar degeneration played by the vacuolating toxin (VacA) was apparent in gastroduodenal epithelial cells. Specially, a number of tumor cells were found in H. pylori-positive gastric intestinal metaplasia (IM) mucosa under TEM which provided an ultrastructural evidence of IM carrying a particularly high risk for the development of gastric cancer.

    Peptic ulcer bleeding is one of the most common emergency situations in medicine. Combined pharmacological and endoscopic therapy together with emerging interventional radiological procedures are successfully treating peptic ulcer disease, reserving surgical procedures for only a small portion of patients unresponsive to 'conventional' therapy. Technological advancement has seen a great improvement in the field of endoscopic treatment in the form of various methods of hemostasis. However, pharmacological therapy with proton pump inhibitors still plays the central role in the peptic ulcer bleeding treatment algorithm.

    Peptic ulceration occurs when the digestive action of gastric secretions overcomes gastroduodenal mucosal defences. The therapeutic strategy used to correct this imbalance uses drugs that either reduce gastric secretion or increase mucosal resistance. Traditional therapies of dietary manipulation and antacid administration no longer play major roles in peptic ulcer therapy. Uncomplicated peptic ulcers respond quite well to drug treatment, although recurrences are common and may require long-term maintenance therapy. Drug-induced gastric ulcers have represented a challenging problem, for which effective therapy is now available. PMID:21249091

    Nodular gastritis is a form of chronic Helicobacter pylori gastritis affecting the gastric antrum and characterised endoscopically by the presence of small nodular lesions resembling gooseflesh. It is generally accepted that hyperplasia of lymphoid follicles histologically characterises nodular gastritis; however, quantitative analysis in support of this hypothesis has not been reported. Our goal was to determine whether nodular gastritis is characterised by lymphoid follicle hyperplasia.The number, size, and location of lymphoid follicles in nodular gastritis were determined and those properties compared to samples of atrophic gastritis. The percentages of high endothelial venule (HEV)-like vessels were also evaluated.The number of lymphoid follicles was comparable between nodular and atrophic gastritis; however, follicle size in nodular gastritis was significantly greater than that seen in atrophic gastritis. Moreover, lymphoid follicles in nodular gastritis were positioned more superficially than were those in atrophic gastritis. The percentage of MECA-79 HEV-like vessels was greater in areas with gooseflesh-like lesions in nodular versus atrophic gastritis.Superficially located hyperplastic lymphoid follicles characterise nodular gastritis, and these follicles correspond to gooseflesh-like nodular lesions observed endoscopically. These observations suggest that MECA-79 HEV-like vessels could play at least a partial role in the pathogenesis of nodular gastritis.

    The authors present their experience in the endoscopic laser photocoagulation of bleeding peptic ulcer. From 1991 to June 1995, 203 patients admitted for UGI bleeding from peptic ulcer have been treated by this method. The source of bleeding was confirmed by endoscopy. The patients were divided into two groups: actively bleeding peptic ulcer (group IA and IB according to Forrest's classification) and ulcer with stigmata of recent bleeding (group IIA/IIB). The former group consisted of 106 patients, among whom over 40 percent (45 patients) presented signs of hypovolemic shock on admission. Nd:YAG laser (Surgical Laser Technologies) was used in a continuous mode with a contact (8 - 20 watts) or non-contact (over 50 watts) method of coagulation. In actively bleeding patients photocoagulation resulted in stopping the hemorrhage in 95 (90%). Recurrent bleeding occurred in 16 cases; in 9 of them it was stopped by repeated photocoagulation. In this group 18 patients required surgical intervention. The mortality was of 10.3% (11 patients). In 97 patients with recent bleeding stigmata photocoagulation provoked heavy hemorrhage in 3 (in 2 cases stopped by prolonged coagulation). In 9 of the remaining 94 patients recurrent bleeding occurred. Nine patients required surgical intervention. Mortality in this group was of 6%.

  2. The limitations of current therapy in peptic ulcer disease.

    The current therapeutic approach to peptic ulcer disease includes agents that reduce gastric acidity and hence peptic activity, inactivate or adsorb pepsin, create a physical barrier against the effects of acid and pepsin, or enhance mucosal defence. Profound gastric acid reduction may predispose to infection, and it has been suggested that carcinogenesis is possible, although a cause-effect relationship has never been established. The side-effects of therapy are well-described, and may limit the therapeutic approach. Healing rates correlate closely with acid suppression in duodenal ulcer, but not entirely in gastric ulcer. Maintenance therapy lowers the relapse rate, but does not alter the ulcer diathesis. The optimal strategy for long-term management remains unclear, but in the future one should consider outcome measures which include a decrease in pain, improvement in the quality of life, reduction work loss, and a reduction of complications, in addition to ulcer healing. The ideal therapy should be efficacious, safe, and convenient--with no side-effects--and cost-effective. New agents should suppress acid and peptic activity, while enhancing the gastric mucosal defence mechanisms (such as mucosal blood flow, mucus, and bicarbonate secretion) and stimulating gastric cellular regeneration and restitution.

    Much has been written about gastric mucosae behavior and the occurrence of intestinal metaplasia. The aim of this paper is to learn something more about these matters in peruvian population. We selected 100 patients with endoscopically no localized lesions between 30 to 70 years of age. We took 8 samples of gastric mucosae in each patient which were carefully examined for the presence of inflammatory changes, settle the line type between antral and fundic mucosae and the frequency of intestinal metaplasia finding. The results showed disagreement between endoscopic and histological findings, so we conclude it is better to diagnose chronic gastritis on the basis of histological parameters. The line between antral and fundic mucosae was of the close type one found in 87% of all cases and it advanced proximally with increasing age. Intestinal metaplasia was present in 46% of the whole number of patients and the rate of occurrence increased in 50% over 50 years age. These findings will let us compare future investigations of gastric mucosae behavior with localized benign or malign lesions.

    Urease in the human gastric mucosa is a marker for infection with Campylobacter pylori (CP), an organism suspected of causing chronic gastritis and peptic ulceration. To detect gastric urease, we examined 32 patients who were being evaluated for possible peptic ulcer disease. Fasting patients were given 10 microCi (370 kBq) of /sup 14/C-labeled urea. Breath samples were collected in hyamine at intervals between 1 and 30 min. The amount of /sup 14/C collected at these times was expressed as: body weight X (% of administered dose of /sup 14/C in sample)/(mmol of CO/sub 2/ collected). The presence of C. pylori colonization was also determined by examination of multiple endoscopic gastric biopsy specimens. On average, patients who were proven to have C. pylori infection exhaled 20 times more labeled CO/sub 2/ than patients who were not infected. The difference between infected patients and C. pylori negative control patients was highly significant at all time points between 2 and 30 min after ingestion of the radionuclide (p less than 0.0001). The noninvasive urea breath is less expensive than endoscopic biopsy of the stomach and more accurate than serology as a means of detecting Campylobacter pylori infection. Because the test detects actual viable CP organisms, it can be used to confirm eradication of the bacterium after antibacterial therapy.

    Captive cheetahs have an unusually severe progressive gastritis that is not present in wild cheetahs infected with the same strains of Helicobacter. This gastritis, when severe, has florid lymphocyte and plasma cell infiltrates in the epithelium and lamina propria with gland destruction, parietal cell loss, and, in some cases, lymphoid follicles. The local gastric immune response was characterized by immunohistochemistry in 21 cheetahs with varying degrees of gastritis. The character of the response was similar among types of gastritis except that cheetahs with severe gastritis had increased numbers (up to 70%) of lamina proprial CD79a+CD21- B cells. CD3+CD4+ T cells were present in the lamina propria, and CD3+CD8α+ T cells were within the glandular epithelium. Lymphoid aggregates had follicular differentiation with a central core of CD79a+/CD45R+ B cells and with an outer zone of CD3+ T cells that expressed both CD4 and CD8 antigens. MHC II antigens were diffusely expressed throughout the glandular and superficial epithelium. No cheetah had evidence of autoantibodies against the gastric mucosa when gastric samples from 30 cheetahs with different degrees of gastritis were incubated with autologous and heterologous serum. These findings indicate that T-cell distribution in cheetahs is qualitatively similar to that in other species infected with Helicobacter but that large numbers of lamina propria activated B cells and plasma cells did distinguish cheetahs with severe gastritis. Further research is needed to determine whether alterations in the Th1:Th2 balance are the cause of this more plasmacytic response in some cheetahs.

    Phlegmonous gastritis is a rare and rapidly progressive bacterial infection of the stomach wall, with a high mortality rate. Antibiotics with or without surgical treatment are required for treatment. We present a case in which phlegmonous gastritis occurred during the diagnostic evaluation of early gastric cancer. The patient showed improvement after antibiotic treatment, but attempted endoscopic submucosal dissection failed because of submucosal pus. We immediately applied argon plasma coagulation since surgical resection was also considered a high-risk procedure because of the submucosal pus and multiple comorbidities. However, there was local recurrence two years later, and the patient underwent subtotal gastrectomy with lymph node dissection. Considering the risk of incomplete treatment immediately after recovery from phlegmonous gastritis and that recurrent disease can be more difficult to manage, delaying treatment and evaluation until after complete recovery of PG might be a better option in this particular clinical situation.

    The changes caused by Helicobacter pylori are a slow, progressing inflammatory process developing from several to dozen years. H. pylori infection leads to an inflammatory response in the gastric mucosa with granulocyte infiltrates in an acute form of the inflammation, and lymphocytes, plasmatic, macrophages and eosinophils in a chronic form inducing the development of gastric and duodenal ulcers and gastric cancer in some patients. The frequency and the type of morphological changes in the gastric mucosa were analyzed in children with positive IgG against H. pylori and the incidence of gastric and duodenal ulcers in family members of children examined was evaluated in our study. Gastritis was reported in 68.8% of children with positive IgG against H. pylori. Gastric ulcer was confirmed in 37.1% of families of children included in the study. Duodenal ulcers were found in 22.9% of families. The results obtained, indicate the usefulness of long-term observation and clinical follow-up of children with chronic gastritis of H. pylori ethiology taking into consideration bacterium eradication as prophylaxis of peptic ulceration.

    Peptic ulcer disease (PUD) occurs after a long-term Helicobacter pylori infection. However, the disease can develop earlier, and rare cases have been observed in children, suggesting that these H. pylori strains may be more virulent. We used suppressive subtractive hybridization for comparative genomics between H. pylori strains isolated from a 5-year-old child with duodenal ulcer and from a sex- and age-matched child with gastritis only. The prevalence of the 30 tester-specific subtracted sequences was determined on a collection of H. pylori strains from children (15 ulcers and 30 gastritis) and from adults (46 ulcers and 44 gastritis). Two of these sequences, jhp0562 (80.0% versus 33.3%, P = 0.008) and jhp0870 (80.0% versus 36.7%, P = 0.015), were highly associated with PUD in children and a third sequence, jhp0828, was less associated (40.0% versus 10.0%, P = 0.048). Among adult strains, none of the 30 sequences was associated with PUD. However, both jhp0562 and jhp0870 were less prevalent in adenocarcinoma strains than in PUD strains from children and adults, the difference being statistically significant for jhp0870. In conclusion, two H. pylori genes were identified as being strongly associated with PUD in children, and their putative roles as an outer membrane protein for jhp0870 and in lipopolysaccharide biosynthesis for jhp0562, suggest that they may be novel virulence factors of H. pylori.

    Peptic ulcer bleeding is a frequent cause of admission. Despite several advances in treatment the 30-day mortality seems unchanged at a level around 11%. Use of risk scoring systems is shown to be advantageous in the primary assessment of patients presenting with symptoms of peptic ulcer bleeding. Studies performed outside Denmark have demonstrated that use of risk scoring systems facilitates identification of low-risk patients suitable for outpatient management. Nevertheless, these systems have not been implemented for routine use in Denmark. This is mainly explained by concerns about the external validity due to considerable inter-country variation in patients' characteristics. In recent years, transcatheter arterial embolization (TAE) has become increasingly used for achievement of haemostasis in patients with peptic ulcer bleeding not responding to endoscopic therapy. As rebleeding is associated with poor outcome TAE could, in theory, also be beneficial as a supplementary treatment in patients with ulcer bleeding responding to endoscopic therapy. This has not been examined previously. Several studies have concluded that peptic ulcer bleeding is associated with excess long-term mortality. These findings are, however, questioned as the studies were based on life-table analysis, unmatched control groups, or did not perform adequate adjustment for comorbidity. Treatment with blood transfusion is, among patients undergoing cardiac bypass surgery, shown to increase the long-term mortality. Despite frequent use of blood transfusion in treatment of peptic ulcer bleeding a possible adverse effect of on long-term survival has not been examined in these patients.

    The impact of risk factors on the development of peptic ulcers has been shown to vary among different populations. We sought to establish a correlation between these factors and their involvement in the occurrence of peptic ulcers for which a canonical correlation analysis was applied. We included 7,014 patient records (48.6% women, 18.4% duodenal ulcer [DU], 4.6% gastric ulcer [GU]) of those underwent upper gastroendoscopy for the last 5 years. The variables measured are endoscopic findings (DU, GU, antral gastritis, erosive gastritis, pangastritis, pyloric deformity, bulbar deformity, bleeding, atrophy, Barret esophagus and gastric polyp) and risk factors (age, gender, Helicobacter pylori infection, smoking, alcohol, and nonsteroidal anti-inflammatory drugs [NSAIDs] and aspirin intake). We found that DU had significant positive correlation with bulbar deformity (P=2.6 x 10(-23)), pyloric deformity (P=2.6 x 10(-23)), gender (P=2.6 x 10(-23)), H. pylori (P=1.4 x 10(-15)), bleeding (P=6.9 x 10(-15)), smoking (P=1.4 x 10(-7)), aspirin use (P=1.1 x 10(-4)), alcohol intake (P=7.7 x 10(-4)), and NSAIDs (P=.01). GU had a significantly positive correlation with pyloric deformity (P=1,6 x 10(-15)), age (P=2.6 x 10(-14)), bleeding (P=3.7 x 10(-8)), gender (P=1.3 x 10(-7)), aspirin use (P=1.1 x 10(-6)), bulbar deformity (P=7.4 x 10(-4)), alcohol intake (P=.03), smoking (P=.04), and Barret esophagus (P=.03). The level of significance was much higher in some variables with DU than with GU and the correlations with GU in spite of being highly significant the majority, were small in magnitude. In conclusion, Turkish patients with the following endoscopic findings bulbar deformity and pyloric deformity are high-risk patients for peptic ulcers with the risk of the occurrence of DU being higher than that of GU. Factors such as H. pylori, smoking, alcohol use, and NSAIDs use (listed in a decreasing manner) are risk factors that have significant impact on the occurrence of DU

    A perforated peptic ulcer in a child is a rare entity. Severe abdominal pain in an ill-appearing child with a rigid abdomen and possibly with signs of shock is the typical presenting feature of this life-threatening complication of peptic ulcer disease. We present a case of a 14.5-year-old adolescent girl who developed abdominal and shoulder pain that resolved after 1 day. She was then completely well for 2 days until the abdominal and shoulder pain recurred. On examination, she appeared well, but in pain. A chest radiograph revealed a large pneumoperitoneum. She underwent emergent laparoscopic omental patch repair of a perforated ulcer on the anterior wall of her stomach. Result of a urea breath test to detect Helicobacter pylori was negative. The differential diagnosis of pneumoperitoneum in children is discussed, as are childhood perforated peptic ulcer in general, and the unique clinical features present in this case in particular.

Pre-endoscopic considerations, such as the use of prokinetics and timing of endoscopy, are reviewed. In addition, this article examines aspects of postendoscopic care such as the effectiveness, dosing, and duration of postendoscopic proton-pump inhibitors, Helicobacter pylori testing, and benefits of treatment in terms of preventing rebleeding; and the use of nonsteroidal anti-inflammatory drugs, antiplatelet agents, and oral anticoagulants, including direct thrombin and Xa inhibitors, following acute peptic ulcer bleeding.

    Treatment of peptic ulcer disease has undergone a radical change due to the discovery of its main cause, the Helicobacter pylori infection. The management of the chronic infection is now the primary aim. Treatment of peptic ulcer essentially consists of eradicating H. pylori. A current problem is the resistance developed by H. pylori to the antibiotics used in eradication regimen. Ulcers that are induced by nonsteroidal antirheumatic (NSAR) agents and acetylsalicylic acid are gaining in importance. Optimized inhibition of acid secretion with proton pump inhibitors has made it possible to both prevent and cure ulcers in the stomach and duodenum caused by NSAR agents.

    The incidence of peptic ulcer has steadily declined through out the world. This decreasing trend is also noticeable in this subcontinent. The point prevalence of peptic ulcer (PUD) in Bangladesh was around 15% in eighties. The aim of this study was to see the present prevalence of peptic ulcer at endoscopy and to identify changing trends in the occurrence of peptic ulcer in Bangladesh. This retrospective analysis of the endoscopic records of multiple tertiary referral centres of Dhaka city were done from January 2012 to July 2013. A total of 5608 subjects were the study samples. We included those patients having peptic ulcer in the form of duodenal ulcer, benign gastric ulcer including pre-pyloric ulcer and gastric outlet obstruction due to peptic ulcer. Duodenal ulcer and benign gastric ulcer were found in 415(7.4%) and 184(3.28%) patients respectively and gastric outlet obstruction due to peptic ulcer was found in 23(0.40%) patients.

    Collagenous gastritis (CG) characterized by the deposition of a subepithelial collagen band and accompanying inflammatory infiltrate is a rare disorder. The natural history and pathogenesis of CG remain unclear. We describe the histologic features (23 gastric, 18 duodenal, and 4 colonic biopsies) and clinical findings of an additional 12 cases. Histologic features including active or chronic inflammation, surface epithelial injury, intraepithelial lymphocytosis, intestinal metaplasia, and Helicobacter pylori, and measurement of thickness of subepithelial collagenous band were evaluated in gastric biopsies. The clinical features, endoscopic findings, and follow-up were obtained and correlated with histologic features. There was an even number of males (n=6) and females (n=6). Four patients were children/young adults, 3 of whom (75%) presented with anemia and gastric nodularity. Eight patients were adults, 6 of whom (75%) had an associated autoimmune disease (1 with Hashimoto thyroiditis and polymyositis) or other intestinal disease (3 with celiac sprue, 1 with collagenous colitis, 1 with collagenous sprue), in contrast to none in the 4 children/young adults, P=0.06. The range of subepithelial collagen thickness was 15 to 120 microm in CG. The collagenous layer showed surface epithelial injury and entrapped inflammatory cells. On presentation, the thickened collagen distribution in the antrum and body was variably patchy and diffuse. Four (33%) patients showed lymphocytic gastritis (3 within the same biopsy); one of these patients also had celiac sprue and another had collagenous sprue. Three (25%) patients had celiac sprue (2 had duodenal biopsy proven and 1 had a clinical diagnosis of celiac sprue). An additional patient had duodenal biopsies showing collagenous sprue. Four patients had follow-up biopsies during a 3 to 119-month period after the diagnosis of CG. CG persisted on the follow-up gastric biopsies in 3 (75%) of the 4 patients, and the other patient had

    Acid peptic disorders are the result of distinctive, but overlapping pathogenic mechanisms leading to either excessive acid secretion or diminished mucosal defense. They are common entities present in daily clinical practice that, owing to their chronicity, represent a significant cost to healthcare. Key elements in the success of controlling these entities have been the development of potent and safe drugs based on physiological targets. The histamine-2 receptor antagonists revolutionized the treatment of acid peptic disorders owing to their safety and efficacy profile. The proton-pump inhibitors (PPIs) represent a further therapeutic advance due to more potent inhibition of acid secretion. Ample data from clinical trials and observational experience have confirmed the utility of these agents in the treatment of acid peptic diseases, with differential efficacy and safety characteristics between and within drug classes. Paradigms in their speed and duration of action have underscored the need for new chemical entities that, from a single dose, would provide reliable duration of acid control, particularly at night. Moreover, PPIs reduce, but do not eliminate, the risk of ulcers in patients taking NSAIDs, reflecting untargeted physiopathologic pathways and a breach in the ability to sustain an intragastric pH of more than 4. This review provides an assessment of the current understanding of the physiology of acid production, a discussion of medications targeting gastric acid production and a review of efficacy in specific acid peptic diseases, as well as current challenges and future directions in the treatment of acid-mediated diseases.

    Abstract Autoimmune gastritis is often suspected for its hematologic findings, and rarely the diagnosis is made for the presence of gastrointestinal symptoms. Aims of this cross-sectional study were to assess in a large cohort of patients affected by autoimmune gastritis the occurrence and the pattern of gastrointestinal symptoms and to evaluate whether symptomatic patients are characterized by specific clinical features. Gastrointestinal symptoms of 379 consecutive autoimmune gastritis patients were systematically assessed and classified following Rome III Criteria. Association between symptoms and anemia pattern, positivity to gastric autoantibodies, Helicobacter pylori infection, and concomitant autoimmune disease were evaluated. In total, 70.2% of patients were female, median age 55 years (range 17–83). Pernicious anemia (53.6%), iron deficiency anemia (34.8%), gastric autoantibodies (68.8%), and autoimmune disorders (41.7%) were present. However, 56.7% of patients complained of gastrointestinal symptoms, 69.8% of them had exclusively upper symptoms, 15.8% only lower and 14.4% concomitant upper and lower symptoms. Dyspepsia, subtype postprandial distress syndrome was the most represented, being present in 60.2% of symptomatic patients. Univariate and multivariate analyses showed that age <55 years (OR 1.6 [CI:1–2.5]), absence of smoking habit (OR 2.2 [CI:1.2–4]), and absence of anemia (OR 3.1 [CI:1.5–6.4]) were independent factors associated to dyspepsia. Autoimmune gastritis is associated in almost 60% of cases with gastrointestinal symptoms, in particular dyspepsia. Dyspepsia is strictly related to younger age, no smoking, and absence of anemia.

    The histologic finding of chronic inflammation in an endoscopic mucosal biopsy of the stomach (chronic gastritis) is very common and usually reflects the presence of Helicobacter pylori infection. However, infectious organisms are not always present in biopsy material, and some cases of chronic gastritis do not result from H. pylori infection. Thus, the differential diagnosis of this finding is an important one for pathologists to keep in mind. This review presents the three most common and clinically significant causes of chronic, noninfectious gastritis, namely, autoimmune atrophic gastritis, lymphocytic gastritis, and gastric involvement in the setting of inflammatory bowel disease, especially Crohn disease. For each entity, a brief discussion of its etiology and pathogenesis, a review of the clinical and endoscopic features, and a description of the microscopic findings are presented in the context of the differential diagnosis of chronic gastritis with emphasis on helpful histopathologic hints and long-term sequelae.

    The objective of this study was to explore hair mercury level in association with chronic atrophic gastritis, a precancerous stage of gastric cancer (GC), and thus provide a brand new angle of view on the timely intervention of precancerous stage of GC. We recruited 149 healthy volunteers as controls and 152 patients suffering from chronic gastritis as cases. The controls denied upper gastrointestinal discomforts, and the cases were diagnosed as chronic superficial gastritis (n=68) or chronic atrophic gastritis (n=84). We utilized Mercury Automated Analyzer (NIC MA-3000) to detect hair mercury level of both healthy controls and cases of chronic gastritis. The statistic of measurement data was expressed as mean ± standard deviation, which was analyzed using Levene variance equality test and t test. Pearson correlation analysis was employed to determine associated factors affecting hair mercury levels, and multiple stepwise regression analysis was performed to deduce regression equations. Statistical significance is considered if p value is less than 0.05. The overall hair mercury level was 0.908949 ± 0.8844490 ng/g [mean ± standard deviation (SD)] in gastritis cases and 0.460198 ± 0.2712187 ng/g (mean±SD) in healthy controls; the former level was significantly higher than the latter one (p=0.000<0.01). The hair mercury level in chronic atrophic gastritis subgroup was 1.155220 ± 0.9470246 ng/g (mean ± SD) and that in chronic superficial gastritis subgroup was 0.604732 ± 0.6942509 ng/g (mean ± SD); the former level was significantly higher than the latter level (p<0.01). The hair mercury level in chronic superficial gastritis cases was significantly higher than that in healthy controls (p<0.05). The hair mercury level in chronic atrophic gastritis cases was significantly higher than that in healthy controls (p<0.01). Stratified analysis indicated that the hair mercury level in healthy controls with eating seafood was significantly higher than that in healthy

    Lymphocytic gastritis and primary gastric lymphoma are rare conditions with unknown aetiology. It has recently been suggested that Helicobacter pylori has a role in the pathogenesis of both of them. The occurrence of lymphocytic gastritis and H pylori was studied in a series of patients with primary gastric lymphoma. The cases of primary gastric lymphomas (n = 35) diagnosed in years 1970-1993 were identified. The specimens of 22 cases contained gastric mucosa sufficiently so that the number of intra-epithelial lymphocytes, severity of gastritis, and occurrence of H pylori could be studied. Lymphocytic gastritis was detected in seven of 22 patients (32%), and in most cases both in antral and body mucosa. Atrophy of the body glands was significantly more severe in lymphocytic gastritis patients. H pylori was detected in 13 of all 22 patients (59%); two of seven lymphocytic gastritis patients (29%), and 11 of 15 (73%) of patients without lymphocytic gastritis were H pylori positive. Patients with gastric lymphoma have significantly increased prevalence of lymphocytic gastritis. Rarity of H pylori in these patients might be connected with atrophic changes in body mucosa. Further studies are needed to show the significance of lymphocytic gastritis as a precursor of gastric lymphoma. Images Figure 2 Figure 3 Figure 4 PMID:7489930

    Curcuma aromatica is an herbal medicine and traditionally used for the treatment of various diseases in Asia. We investigated the effects of C. aromatica water extract (CAW) in the stomach of rats with ethanol-induced gastritis. Gastritis was induced in rats by intragastric administration of 5 mL/kg body weight of absolute ethanol. The CAW groups were given 250 or 500 mg of extract/kg 2 h before administration of ethanol, respectively. To determine the antioxidant effects of CAW, we determined the level of lipid peroxidation, the level of reduced glutathione (GSH), the activities of catalase, degree of inflammation, and mucus production in the stomach. CAW reduced ethanol-induced inflammation and loss of epithelial cells and increased the mucus production in the stomach. CAW reduced the increase in lipid peroxidation associated with ethanol-induced gastritis (250 and 500 mg/kg, p < 0.01, resp.) and increased mucosal GSH content (500 mg/kg, p < 0.01) and the activity of catalase (250 and 500 mg/kg, p < 0.01, resp.). CAW increased the production of prostaglandin E2. These findings suggest that CAW protects against ethanol-induced gastric mucosa injury by increasing antioxidant status. We suggest that CAW could be developed for the treatment of gastritis induced by alcohol. PMID:26483844

    Ulcerative colitis seldom associated with nutritive and/or salicylate allergy. Authors present a case of both allergic events at the course of the disease. In 1996 a 19-year-old girl was referred with a history of blood in stool as well as diarrhoea, suggesting ulcerative proctitis. Biopsy revealed ulcerative colitis of the rectum mucosa with eosinophilic infiltration and 20% peripheral eosinophilia was found. Allergic origin and worm infection were ruled out, and after tinidazol treatment, four year elapsed without any signs or symptoms. In December 2000 blood in stools and upper abdominal complaints developed without peripheral eosinophilia. Gastroscopy and biopsy showed a mild chronic gastritis. Olsalazine, budesonide enema and famotidin treatment were started, but then later changed to mesalazine and pantoprazol, because of the constant stomach complaints. The next five months passed without any symptoms. The patient had to break off her seashore journey in July 2000 because of stomach complaints, vomiting and exsiccosis. Peripheral eosinophilia (27.3%) was evident. Gastroscopy revealed erosive ulcers and the biopsy showed eosinophilic gastritis. Biopsies from the jejunum, duodenum and antrum as well as enteroscopy and biopsies from the rectum showed mild eosinophilic infiltration. An allergy test proved the presence of IgE against salicylate, egg protein, seafood protein and the lymphocyte transformation test was also positive against salicylate. Oral food challenges proved to be negative and the amino-salicylate treatment was stopped. After a temporary symptom free period, bloody stools reappeared in May 2003; the peripheral eosinophilia still existed, but had decreased (22.2%). Esomeprazol, and methyl-prednisolone containing enema (40 mg/day/2 weeks) followed by budesonide enema twice a week resulted in a symptom free period and peripheral eosinophilia became almost normalised (6.2%).

    Helicobacter pylori (H pylori) gastritis presents a risk of cancer related to atrophy and intestinal metaplasia. Two recent classifications OLGA (Operative Link on Gastritis Assessment) and OLGIM (Operative Link on Gastritic Intestinal Metaplasia assessment) have been proposed to identify high-risk forms (stages III and IV). The aim of this study is to evaluate the OLGA and OLGIM staging systems in H pylori gastritis. A descriptive study of 100 cases of chronic H pylori gastritis was performed. The revaluation of Sydney System parameters of atrophy and intestinal metaplasia, of gastric antrum and corpus, allowed identifying respectively the stages of OLGA and OLGIM systems. The progressive risk of our H pylori gastritis was 6% according to OLGA staging and 7% according to OLGIM staging. Significant correlation was revealed between age and OLGA staging. High-risk gastritis according to OLGIM staging was significantly associated with moderate to severe atrophy. High-risk forms according to OLGA staging were associated in 80% of the cases to intestinal metaplasia. OLGA and OLGIM systems showed a highly significant positive correlation between them with a mismatch at 5% for H pylori gastritis. The OLGA and OLGIM staging systems in addition to Sydney System, allow selection of high risk forms of chronic gastritis requiring accurate observation.

    Intestinal-type gastric adenocarcinomas usually are preceded by chronic atrophic gastritis. Studies of gastric cancer prevention often rely on identification of this condition. In a clinical trial, we sought to determine the best serological screening method for chronic atrophic gastritis and compared our findings to the published literature. Test characteristics of potential screening tests (antibodies to Helicobacter pyloni or CagA, elevated gastrin, low pepsinogen, increased age) alone or in combination were examined among consecutive subjects enrolled in a study of H. pylori and preneoplastic gastric lesions in Chiapas, Mexico; 70% had chronic atrophic gastritis. English-language articles concerning screening for chronic atrophic gastritis were also reviewed. Sensitivity for chronic atrophic gastritis was highest for antibodies to H. pylori (92%) or CagA, or gastrin levels >25 ng/l (both 83%). Specificity, however, was low for these tests (18, 41, and 22%, respectively). Pepsinogen levels were highly specific but insensitive markers of chronic atrophic gastritis (for pepsinogen I <25 microg/l, sensitivity was 6% and specificity was 100%; for pepsinogen I:pepsinogen II ratio <2.5, sensitivity was 14% and specificity was 96%). Combinations of markers did not improve test characteristics. Screening test characteristics from the literature varied widely and did not consistently identify a good screening strategy. In this study, CagA antibodies alone had the best combination of test characteristics for chronic atrophic gastritis screening. However, no screening test was both highly sensitive and highly specific for chronic atrophic gastritis.

    Gastritis and gastric ulcers are an important cause of morbidity and mortality in canine athletes. Although the majority of scientific work on this condition has been performed in ultraendurance racing sled dogs, this condition has been identified in other canine athletes, including sled dogs competing in shorter events and dogs performing off-leash explosive detection duties. The cause of the syndrome is unknown, but current hypotheses propose a link between exercise-induced hyperthermia and loss of gastric mucosal barrier function as an early event in the pathogenesis. Treatment is focused on prevention of clinical disease using acid secretion inhibitors, such as omeprazole, which has excellent efficacy in controlled clinical studies.

    The gastrointestinal system of horses is affected by a large variety of inflammatory infectious and noninfectious conditions. The most prevalent form of gastritis is associated with ulceration of the pars esophagea. Although the diagnostic techniques for alimentary diseases of horses have improved significantly over the past few years, difficulties still exist in establishing the causes of a significant number of enteric diseases in this species. This problem is compounded by several agents of enteric disease also being found in the intestine of clinically normal horses, which questions the validity of the mere detection of these agents in the intestine.

    AIM: To determine the protective effect of triple viable probiotics on gastritis induced by Helicobacter pylori (H. pylori) and elucidate the possible mechanisms of protection. METHODS: Colonization of BIFICO strains in the mouse stomach was determined by counting colony-forming units per gram of stomach tissue. After treatment with or without BIFICO, inflammation and H. pylori colonization in the mouse stomach were analyzed by hematoxylin and eosin and Giemsa staining, respectively. Cytokine levels were determined by enzyme-linked immunosorbent assay and Milliplex. The activation of nuclear factor (NF)-κB and MAPK signaling in human gastric epithelial cells was evaluated by Western blot analysis. Quantitative reverse transcription-polymerase chain reaction was used to quantify TLR2, TLR4 and MyD88 mRNA expression in the mouse stomach. RESULTS: We demonstrated that BIFICO, which contains a mixture of Enterococcus faecalis, Bifidobacterium longum and Lactobacillus acidophilus, was tolerant to the mouse stomach environment and was able to survive both the 8-h and 3-d courses of administration. Although BIFICO treatment had no effect on the colonization of H. pylori in the mouse stomach, it ameliorated H. pylori-induced gastritis by significantly inhibiting the expression of cytokines and chemokines such as TNF-α, IL-1β, IL-10, IL-6, G-CSF and MIP-2 (P < 0.05). These results led us to hypothesize that BIFICO treatment would diminish the H. pylori-induced inflammatory response in gastric mucosal epithelial cells in vitro via the NF-κB and MAPK signaling pathways. Indeed, we observed a decrease in the expression of the NF-κB subunit p65 and in the phosphorylation of IκB-α, ERK and p38. Moreover, there was a significant decrease in the production of IL-8, TNF-α, G-CSF and GM-CSF (P < 0.05), and the increased expression of TLR2, TLR4 and MyD88 induced by H. pylori in the stomach was also significantly reduced following BIFICO treatment (P < 0.05).

    Peptic ulcer bleeding is a common disease and recurrent bleeding is an independent risk factor of mortality. Infusion with proton pump inhibitors (PPIs) prevents recurrent bleeding after successful endoscopic therapy. A gastric acidic environment of less than pH 5.4 alters coagulation function and activates pepsin to disaggregate platelet plugs. Gastric acid is secreted by H(+), K(+)-ATPase, naming the proton pump. This update review focuses on the mechanism and the role of PPIs in the clinical management of patients with peptic ulcer bleeding. An intravenous omeprazole bolus followed by high-dose continuous infusion for 72 h after successful endoscopic therapy can prevent the recurrent bleeding. In the Asian, however, the infusion dosage can possibly be diminished whilst preserving favorable control of the intragastric pH and thereby still decreasing rates of recurrent bleeding. Irrespective of the infusion dosage of PPIs, rates of recurrent bleeding remain high in patients with co-morbidities. Because recurrent peptic ulcer bleeding may be prolonged in those with co-morbidities, a low-dose infusion of IV PPIs for up to 7-day may result in better control of recurrent bleeding of peptic ulcers. Due to the inter-patient variability in CYP2C19 genotypes, the infusion form of new generation PPIs, such as esomeprazole, should be promising for the prevention of recurrent bleeding. This article offers a comprehensive review of clinical practice, highlighting the indication, the optimal dosage, the duration, and the potential limitation of PPIs infusion for peptic ulcer bleeding.

    Men with and men without a history of peptic ulcers were compared using respiratory symptoms and spirographic measurements taken from data recorded in an epidemiologic study. Among the 1,049 men examined, 7% reported a history of peptic ulcer. A clear relationship appeared between bronchial hypersecretion and peptic ulcers. It persisted after adjustment for age, smoking habits, social class, and country of origin. Men with ulcers inhaled tobacco smoke more often. Ulcers, smoking, and chronic phlegm were independently related to a lower body build index. It seems that the relationship between smoking and ulcers was greater among men with chronic phlegm, and it is postulated that peptic ulcers and "chronic bronchitis" might be related to a "common secretory disorder." After adjustment for age, men with a history of peptic ulcers had, not a lower FEV1, but a higher vital capacity. A slightly lower FEV1/VC ratio cannot in such cases be considered as an index of chronic airflow limitation.

    Atrophic gastritis remains a difficult histopathological diagnosis with low interobserver agreement. The aim of our study was to compare gastritis staging and interobserver agreement between general and expert gastrointestinal (GI) pathologists using Operative Link for Gastritis Assessment (OLGA) and Operative Link on Gastric Intestinal Metaplasia (OLGIM). We enrolled 835 patients undergoing upper endoscopy in the study. Two general and two expert gastrointestinal pathologists graded biopsy specimens according to the Sydney classification, and the stage of gastritis was assessed by OLGA and OLGIM system. Using OLGA, 280 (33.4 %) patients had gastritis (stage I-IV), whereas with OLGIM this was 167 (19.9 %). OLGA stage III- IV gastritis was observed in 25 patients, whereas by OLGIM stage III-IV was found in 23 patients. Interobserver agreement between expert GI pathologists for atrophy in the antrum, incisura angularis, and corpus was moderate (kappa = 0.53, 0.57 and 0.41, respectively, p < 0.0001), but almost perfect for intestinal metaplasia (kappa = 0.82, 0.80 and 0.81, respectively, p < 0.0001). However, interobserver agreement between general pathologists was poor for atrophy, but moderate for intestinal metaplasia. OLGIM staging provided the highest interobserver agreement, but a substantial proportion of potentially high-risk individuals would be missed if only OLGIM staging is applied. Therefore, we recommend to use a combination of OLGA and OLGIM for staging of chronic gastritis.

    Peptic ulcer is the most common gastrointestinal tract (GIT) disorder in clinical practice, which affects approximately 5-10% of the people during their life. The use of herbal drugs for the prevention and treatment of various diseases is constantly developing throughout the world. This is particularly true with regard to phenolic compounds that probably constitute the largest group of plants secondary metabolites. Phenolic compounds have attracted special attention due to their health-promoting characteristics. In the past ten years a large number of the studies have been carried out on the effects of phenolic compounds on human health. Many studies have been carried out that strongly support the contribution of polyphenols to the prevention of cardiovascular diseases, cancer, osteoporosis, neurodegenerative diseases, and diabetes mellitus, and suggest a role in the prevention of peptic ulcer. Polyphenols display a number of pharmacological properties in the GIT area, acting as antisecretory, cytoprotective, and antioxidant agents. The antioxidant properties of phenolic compounds have been widely studied, but it has become clear that their mechanisms of action go beyond the modulation of oxidative stress. Various polyphenolic compounds have been reported for their anti-ulcerogenic activity with a good level of gastric protection. Besides their action as gastroprotective, these phenolic compounds can be an alternative for the treatment of gastric ulcers.

    Background Helicobacter pylori (HP) infection is implicated in gastric and extra-gastric diseases. While gastritis-related chronic inflammation represents a known trigger of metabolic disturbances, whether metabolic syndrome (MetS) is affected by gastritis status remains unclear. We aimed to clarify the effect of HP-related gastritis on the risk of MetS. Materials and Methods We retrospectively enrolled patients undergoing screening for MetS between 2014 and 2015. Investigations included HP-specific immunoglobulin G (IgG) antibody assays to detect HP infection, and serum pepsinogen assays to evaluate atrophic gastritis status. The risk of MetS was evaluated via multiple logistic regression analyses with two covariates: serum HP infection status (IgG levels) and atrophic gastritis status (two criteria were applied; pepsinogen I/II ratio < 3 or both pepsinogen I levels ≤ 70 μg/L and pepsinogen I/II ratio < 3). Results Of 1,044 participants, 247 (23.7%) were HP seropositive, and 62 (6.0%) had MetS. HP seronegative and seropositive patients had similar risks of MetS. On the other hand, AG (defined in terms of serum PG I/II <3) was significant risk of MetS (OR of 2.52 [95% CI 1.05–7.52]). After stratification according to HP IgG concentration, patients with low HP infection status had the lowest MetS risk (defined as an odds ratio [OR] adjusted for age, sex, smoking, drinking and physical activity status). Taking this result as a reference, patients with negative, moderate, and high HP infection status had ORs (with 95% confidence intervals [CI]) of 2.15 (1.06–4.16), 3.69 (1.12–16.7), and 4.05 (1.05–26.8). Conclusions HP-associated gastritis represents a risk factor for MetS. Research should determine why low and not negative HP infection status is associated with the lowest MetS risk. PMID:27851820

    BACKGROUND—Helicobacter pylori, the main cause of chronic gastritis, is a class I gastric carcinogen. Chronic gastritis progresses to cancer through atrophy, metaplasia, and dysplasia. Precancerous phenotypic expression is generally associated with acquired genomic instability.
AIM—To evaluate the effect of H pylori infection and its eradication on gastric histology, cell proliferation, DNA status, and oncogene expression.
METHODS/SUBJECTS—Morphometric and immunohistochemical techniques were used to examine gastric mucosal biopsy specimens from eight controls, 10 patients with H pylori negative chronic gastritis, 53 with H pylori positive chronic gastritis, and 11 with gastric cancer.
RESULTS—All patients with chronic gastritis were in a hyperproliferative state related to mucosal inflammation, regardless of H pylori infection. Atrophy was present in three of 10 patients with H pylori negative chronic gastritis and in 26 of 53 with H pylori positive chronic gastritis, associated in 18 with intestinal metaplasia. DNA content was abnormal in only 11 patients with atrophy and H pylori infection; eight of these also had c-Myc expression, associated in six cases with p53 expression. Fifty three patients with H pylori positive chronic gastritis were monitored for 12 months after antibiotic treatment: three dropped out; infection was eradicated in 45, in whom cell proliferation decreased in parallel with the reduction in gastritis activity; atrophy previously detected in 21/45 disappeared in five, regressed from moderate to mild in nine, and remained unchanged in seven; complete metaplasia disappeared in 4/14, and markers of genomic instability disappeared where previously present. In the five patients in whom H pylori persisted, atrophy, metaplasia, dysplasia, and markers of genomic instability remained unchanged.
CONCLUSIONS—Chronic H pylori infection seems to be responsible for genomic instability in a subset of cases of H pylori positive

    Misoprostol, a synthetic prostaglandin E1 (PGE1) methyl ester analog has potent antisecretory and cytoprotective effects on the gastric and duodenal mucosa which should make it an effective drug in the treatment of gastric and duodenal ulcer. In two multicenter, randomised, double-blind, controlled studies involving over 900 patients with endoscopically proven benign gastric ulcer and in six similar studies involving over 2000 patients with active duodenal ulcers, differing doses of misoprostol have been compared with either placebo therapy or with conventional doses of cimetidine. In these studies misoprostol 800 mcg daily given as two or four divided doses has been shown to produce rates of complete ulcer healing and pain relief which were significantly superior to placebo therapy and comparable to those achieved with cimetidine. Drug related adverse effects were infrequent. A dose related diarrhea occurred in a small proportion of patients which seldom necessitated suspension of therapy. Because of the known uterotropic effect of prostaglandins the drug should not be used in pregnant women or women of child bearing age unless they are using adequate contraceptive measures. No clinically significant adverse, hematological or biochemical effects have been reported. Two studies suggested that misoprostol reduced the adverse effect of smoking on the healing of duodenal ulcer. In addition, misoprostol has been shown to protect the gastro-duodenal mucosa from the damaging effects of alcohol and non-steroidal anti-inflammatory drugs. This action may prove of value in the treatment of ulcer patients who are inveterate smokers, alcohol users or who are compelled to consume non-steroidal anti-inflammatory drugs for pain relief from rheumatic and allied diseases.

    Peptic ulcer disease is a significant cause of morbidity and in certain cases mortality among affected individuals. Proper identification and treatment of peptic ulcer disease is imperative to decreasing its associated sequellae. The most common causes of peptic ulcer disease are the use of nonsteroidal anti-inflammatory drugs (NSAIDs) and infection with Helicobacter pylori. Initial assessment of the patient with dyspepsia is paramount, as the presence of symptoms will dictate further management. With currently available treatment regimens and the ability to reduce gastrointestinal bleeding it is important for all clinicians to have knowledge of this disease, its diagnosis, and pharmacotherapy.

    Bacillus cereus is increasingly being acknowledged as a serious bacterial pathogen in immunocompromised patients. We present a case of acute necrotizing gastritis caused by B. cereus in a 37-year-old woman with acute myeloblastic leukemia, who recovered following total parenteral nutrition and treatment with imipenem and vancomycin. B. cereus was isolated from gastric mucosa and blood cultures. Up to now, no case of acute necrotizing gastritis due to this organism has been reported.

  4. Pathogenicity island cag, vacA and IS605 genotypes in Mexican strains of Helicobacter pylori associated with peptic ulcers

    PubMed Central

    2011-01-01

    Background Helicobacter pylori is associated with chronic gastritis, peptic ulcers, and gastric cancer. Two major virulence factors of H. pylori have been described: the pathogenicity island cag (cag PAI) and the vacuolating cytotoxin gene (vacA). Virtually all strains have a copy of vacA, but its genotype varies. The cag PAI is a region of 32 genes in which the insertion of IS605 elements in its middle region has been associated with partial or total deletions of it that have generated strains with varying virulence. Accordingly, the aim of this work was to determine the cag PAI integrity, vacA genotype and IS605 status in groups of isolates from Mexican patients with non-peptic ulcers (NPU), non-bleeding peptic ulcers (NBPU), and bleeding peptic ulcers (BPU). Methods The cag PAI integrity was performed by detection of eleven targeted genes along this locus using dot blot hybridization and PCR assays. The vacA allelic, cag PAI genotype 1 and IS605 status were determined by PCR analysis. Results Groups of 16-17 isolates (n = 50) from two patients with NPU, NBPU, and BPU, respectively, were studied. 90% (45/50) of the isolates harbored a complete cag PAI. Three BPU isolates lacked the cag PAI, and two of the NBPU had an incomplete cag PAI: the first isolate was negative for three of its genes, including deletion of the cagA gene, whereas the second did not have the cagM gene. Most of the strains (76%) had the vacA s1b/m1 genotype; meanwhile the IS605 was not present within the cag PAI of any strain but was detected elsewhere in the genome of 8% (4/50). Conclusion The patients had highly virulent strains since the most of them possessed a complete cag PAI and had a vacA s1b/m1 genotype. All the isolates presented the cag PAI without any IS605 insertion (genotype 1). Combined vacA genotypes showed that 1 NPU, 2 NBPU, and 1 BPU patients (66.6%) had a mixed infection; coexistence of H. pylori strains with different cag PAI status was observed in 1 NBPU and 2 BPU (50

    Helicobacter pylori (H. pylori) infection is well known to be associated with chronic gastritis and also development of gastric cancer. Raphanobrassica (RB) is an intergeneric hybrid of the genera Raphanus (radish) and Brassica (cabbages) containing appreciable amounts of glucoraphanin (GR) and glucoraphenin (GRe), which are actively hydrolyzed by the enzyme myrosinase to sulforaphane and sulforaphene, respectively. Both of these metabolites exert antimicrobial and anti-inflammatory activity. The purpose of the present study was to investigate the effect of two freeze-dried products of RB (RB1 and RB2) on H. pylori-induced gastritis in Mongolian gerbils. Six-week-old male Mongolian gerbils were inoculated orally with H. pylori (ATCC 43504), and 2weeks later were fed diets containing no additives or diets supplemented with 2% RB1 (containing both GR and GRe) or 2% RB2 (containing GR only) for 10weeks. In the RB1, but not the RB2 group, mononuclear cell infiltration, mRNA expression of IL-6, and cell proliferation in the gastric mucosa were significantly suppressed. These results indicate that RB1 containing both GR and GRe exerted significant inhibitory effects on H. pylori-induced gastritis in Mongolian gerbils apparently mediated via suppression of IL-6 expression and chronic inflammation.

    A series of 60 gastric endocrine tumors comprised 44 body-fundus argyrophil carcinoids, of which 23 arose in a background of hypergastrinemia and type A chronic atrophic gastritis (A-CAG), mainly with histologic patterns suggestive of an autoimmune process. Only 22 percent (compared with 19 percent of 58 tumor-free A-CAG cases) of 36 carcinoids and 21 percent of 19 A-CAG carcinoids investigated had Helicobacter pylori (HP) colonization, against 50 percent of 14 CAG-associated neuroendocrine carcinomas or mixed endocrine-exocrine tumors, 84 percent of 150 cases with early gastric cancer (p < 0.001 versus carcinoids), mostly with B- or AB-type CAG, 76 percent of 97 tumor-free AB-CAG, and 95 percent of 151 tumor-free B-CAG cases. Secondary hypergastrinemia and local mechanisms activated by chronic autoimmune gastritis are among factors involved in the pathogenesis of relatively indolent CAG-associated carcinoids, whereas active HP gastritis in cooperation with environmental carcinogens may likely cause more severe epithelial transformation, leading to ordinary cancer and, possibly, to neuroendocrine carcinomas or mixed endocrine-exocrine tumors.

    This cross sectional study was designed to see association of chronic gastritis including its type with H. pylori infection. Consecutive patients undergoing endoscopic examination having histopathological evidence of chronic gastritis were enrolled in the study and was done in Sylhet MAG Osmani Medical College from July 2011 to June 2012. Biopsies were taken from antrum, body and fundus in all patients. Histopathological examinations were done using H-E stain and for detection of H. pylori, rapid urease test, anti-H.pylori antibody test and histopathological test with modified Giemsa stain were done. Patients having results positive in at least two methods were considered infected by H. pylori. Total 80 dyspeptic patients having chronic gastritis were evaluated. Out of them 67(83.8%) had H. pylori infection and 13(16.2%) were H. pylori negative. Among all patients 57(71.2%) had pangastritis and 23(28.8%) had antral gastritis with female and male predominance respectively. H. pylori infection was present in 49(86.0%) cases of pangastritis and 18(78.3%) cases of antral gastritis. H. pylori infection was a little higher among males (34, 50.7%) females (33, 49.3%). H. pylori infection is the predominant cause of chronic gastritis and pangastritis is the major type.

    The gastric hormone ghrelin is known as an important factor for energy homeostasis, appetite regulation and control of body weight. So far, ghrelin has mainly been examined as a serological marker for gastrointestinal diseases, and only a few publications have highlighted its role in local effects like mucus secretion. Ghrelin can be regarded as a gastroprotective factor, but little is known about the distribution and activity of ghrelin cells in pathologically modified tissues. We aimed to examine the morphological changes in ghrelin expression under several inflammatory, metaplastic and carcinogenic conditions of the upper gastrointestinal tract. In particular, autoimmune gastritis showed interesting remodeling effects in terms of ghrelin expression within neuroendocrine cell hyperplasia by immunohistochemistry. Using confocal laser microscopy, the gastrin/cholecystokinin receptor (CCKB) could be detected on normal ghrelin cells as well as in autoimmune gastritis. Functionally, we found evidence for a physiological interaction between gastrin and ghrelin in a primary rodent cell culture model. Additionally, we gathered serological data from patients with different basic gastrin levels due to long-term autoimmune gastritis or short-term proton pump inhibitor treatment with slightly reactive plasma gastrin elevations. Total ghrelin plasma levels showed a significantly inverse correlation with gastrin under long-term conditions. Autoimmune gastritis as a relevant condition within gastric carcinogenesis therefore has two effects on ghrelin-positive cells due to hypergastrinemia. On the one hand, gastrin stimulates the proliferation of ghrelinpositive cells as integral part of neuroendocrine cell hyperplasia, while on the other hand, plasma ghrelin is reduced by gastrin and lost in pseudopyloric and intestinal metaplastic areas. Ghrelin is necessary for the maintenance of the mucosal barrier and might play a role in gastric carcinogenesis, if altered under these pre

    ABSTRACT Background: Studies with latest technologies such as endoscopy with magnification and chromoendoscopy showed that various endoscopic aspects are clearly related to infection by Helicobacter pylori (HP). The description of different patterns of erythema in gastric body under magnification of images revived interest in identifying these patterns by standard endoscopy. Aim: To validate the morphologic features of gastric mucosa related to H. pylori infection gastritis allowing predictability of their diagnosis as well as proper targeting biopsies. Methods: Prospective study of 339 consecutive patients with the standard videoendoscope image analysis were obtained, recorded and stored in a program database. These images were studied with respect to the presence or absence of H. pylori, diagnosed by rapid urease test and/or by histological analysis. Were studied: a) normal mucosa appearance; b) mucosal nodularity; c) diffuse nonspecific erythema or redness (with or without edema of folds and exudate) of antrum and body; d) mosaic pattern with focal area of hyperemia; e) erythema in streaks or bands (red streak); f) elevated (raised) erosion; g) flat erosions; h) fundic gland polyps. The main exclusion criteria were the use of drugs, HP pre-treatment and other entities that could affect results. Results: Applying the exclusion criteria, were included 170 of the 339 patients, of which 52 (30.58%) were positive for HP and 118 negative. On the positive findings, the most associated with infection were: nodularity in the antrum (26.92%); presence of raised erosion (15.38%) and mosaic mucosa in the body (21.15%). On the negative group the normal appearance of the mucosa was 66.94%; erythema in streaks or bands in 9.32%; flat erosions 11.86%; and fundic gland polyps 11.86%. Conclusion: Endoscopic findings are useful in the predictability of the result and in directing biopsies. The most representative form of HP related gastritis was the nodularity of the antral mucosa

    Over the past century, since the introduction of non steroidal anti-inflammatory drugs (NSAID), antacid, histamine H2-receptor antagonists (H2RA), proton pump inhibitors (PPI), and discovery of Helicobacter pylori infection, the paradigm of peptic ulcer disease has changed with marked decrease in morbidity and mortality. However, peptic ulcer disease still occupies a position as a major health problem with increase of aged population and NSAIDs usage. In daily general practice, the management of peptic ulcer disease is directed according to the presence of bleeding or not. For non-bleeding peptic ulcer disease, proper acid suppression and the correction of underlying causes such as Helicobacter pylori infection and NSAID use is the main stay of treatment. Though a complete understanding of pathophysiology and a perfect treatment strategy are still a challenge, this guideline aims to provide practical recommendations based on evidences or consensus of experts through in-depth literature review and expert meeting.

    Aims—Type C gastritis caused by bile reflux has a characteristic appearance, similar to that seen in other forms of chemical gastritis, such as those associated with NSAIDs or alcohol. An increase in mucosal cell proliferation increases the likelihood of a neoplastic clone of epithelial cells emerging, particularly where there is chronic epithelial injury associated with bile reflux. It has been shown previously that type C gastritis is associated with increased cell proliferation in the postsurgical stomach. The aim of this study was to determine cell proliferation in type C gastritis caused by bile reflux affecting the intact stomach. Methods—Specimens from 15 patients with a histological diagnosis of type C gastritis on antral biopsy were obtained from the pathology archives between 1994 and 1997. A control group of nine normal antral biopsies was also selected and all underwent MIB-1 immunostaining. The gastric glands were divided into three zones (zone 1, gastric pit; zone 2, isthmus; and zone 3, gland base) and the numbers of positively staining nuclei for 500 epithelial cell nuclei were counted in each zone to determine the percentage labelling index (LI%). Results—Cell proliferation was significantly higher in all three zones of the gastric glands with type C gastritis compared with controls as follows: zone 1, median LI% in type C gastritis 64.7 (range, 7.8–99.2), controls 4.7 (range, 2.0–11.3); zone 2, median LI% in type C gastritis 94.7 (range, 28.8–98.7), controls 40.2 (range, 23.1–70.3); and zone 3, median LI% in type C gastritis 20.0 (range, 1.3–96.0), controls 2.6 (range, 0.9–8.7). Conclusions—Bile reflux is thought to act as a promoter of gastric carcinogenesis in the postsurgical stomach. The same may be true in the intact stomach.

    AIM: To assess expression of matrix metalloproteinases 2 (MMP2) and MMP9 in gastric cancer, superficial gastritis and normal mucosa, and to measure metalloproteinase activity. METHODS: MMP2 and MMP9 mRNA expression was determined by quantitative real-time polymerase chain reaction. Normalization was carried out using three different factors. Proteins were analyzed by quantitative gelatin zymography (qGZ). RESULTS: 18S ribosomal RNA (18SRNA) was very highly expressed, while hypoxanthine ribosyltransferase-1 (HPRT-1) was moderately expressed. MMP2 was highly expressed, while MMP9 was not detected or lowly expressed in normal tissues, moderately or highly expressed in gastritis and highly expressed in cancer. Relative expression of 18SRNA and HPRT-1 showed no significant differences. Significant differences in MMP2 and MMP9 were found between cancer and normal tissue, but not between gastritis and normal tissue. Absolute quantification of MMP9 echoed this pattern, but differential expression of MMP2 proved conflictive. Analysis by qGZ indicated significant differences between cancer and normal tissue in MMP-2, total MMP-9, 250 and 110 kDa bands. CONCLUSION: MMP9 expression is enhanced in gastric cancer compared to normal mucosa; interpretation of differential expression of MMP2 is difficult to establish. PMID:20333791

    Two groups of patients with chronic peptic ulcer were studied to determine the influence of duration of symptoms and age at operation on the result of surgical treatment. Independent physical and psychiatric assessments were made. Statistical analysis of the findings indicates that selection for operation by `earning' is unreliable in that it fails to identify that group of patients liable to do badly. In its place, a combined physical and psychiatric preoperative assessment of the peptic ulcer patient is recommended. PMID:5366281

    The protective effect of capsaicin-sensitive sensory nerve (CSSN) activation was recently demonstrated in human gastric mucosa. We here examined changes in neuropeptides, specifically Substance P (SP), calcitonin-gene related peptide (CGRP) and vasoactive intestinal peptide (VIP) in patients with chronic gastritis or ulcer. Furthermore changes in neprilysin levels, which hydrolyse these neuropeptides, were determined. Gastric biopsies were obtained from both lesion- and normal-appearing mucosa of 57 patients. The presence of H. pylori infection was verified with rapid urease assay. Neuronal and non-neuronal levels of SP, VIP, CGRP and neprilysin activity were determined in freshly frozen biopsies. Immunohistochemical localization of neprilysin was performed in 30 paraffin embedded specimens. We here found that neuronal SP levels decreased significantly in normally appearing mucosa of patients with gastritis while levels of non-neuronal SP increased in diseased areas of gastritis and ulcer. The presence of H. pylori led to further decreases of SP levels. The content of VIP in both disease-involved and uninvolved mucosa, and expression of neprilysin, markedly decreased in patients with gastritis or ulcer. Since VIP, as well as SP fragments, formed following hydrolysis with neprilysin is recognized to have gastroprotective effects, decreased levels of VIP, SP and neprilysin may predispose to cellular damage.

    Helicobacter pylori are considered the most common human pathogen colonizing gastric mucosa. Gastritis with or without H. pylori infection is associated with increase in levels of homocysteine and high-sensitivity C-reactive protein (hs-CRP) but a more pronounced increase is noted in gastritis with H. pylori infection. Increasing level of homocysteine, due to decreased absorption of vitamin B12 and folic acid, together with increased CRP levels in gastritis with H. pylori infection may be the earliest event in the process of atherosclerosis and plaque formation. Retrospective study conducted at tertiary care hospital in Mumbai by Department of Biochemistry in association with Department of Surgery. Eighty patients who underwent gastroscopy in view of gastritis were subjected to rapid urease test for diagnosis of H. pylori infection. Vitamin B12, folic acid, homocysteine and hs-CRP were analyzed using chemiluminescence immuno assay. Student’s t-test, Pearson’s correlation and linear regression used for statistical analysis. Patients with H. pylori gastritis had significantly lower levels of vitamin B12 (271.6±101.3 vs 390.6±176.7 pg/mL; P=0.0005), as well as higher levels of homocysteine (17.4±7.4 vs 13.8±7.8 µmol/L; P=0.037) and hs-CRP (2.5±2.9 vs 1.2±1.1 mg/L; P=0.017), than in patients without H. pylori gastritis. However, folic acid showed (8.9±3.2 vs 10.0±3.6 ng/mL; P=0.171) no significant difference. Elevated homocysteine and hs-CRP in H. pylori gastritis may independently induce endothelial dysfunction, leading to cardiovascular pathology. PMID:25918633

    Objective To present results of the Kyoto Global Consensus Meeting, which was convened to develop global consensus on (1) classification of chronic gastritis and duodenitis, (2) clinical distinction of dyspepsia caused by Helicobacter pylori from functional dyspepsia, (3) appropriate diagnostic assessment of gastritis and (4) when, whom and how to treat H. pylori gastritis. Design Twenty-three clinical questions addressing the above-mentioned four domains were drafted for which expert panels were asked to formulate relevant statements. A Delphi method using an anonymous electronic system was adopted to develop the consensus, the level of which was predefined as ≥80%. Final modifications of clinical questions and consensus were achieved at the face-to-face meeting in Kyoto. Results All 24 statements for 22 clinical questions after extensive modifications and omission of one clinical question were achieved with a consensus level of >80%. To better organise classification of gastritis and duodenitis based on aetiology, a new classification of gastritis and duodenitis is recommended for the 11th international classification. A new category of H. pylori-associated dyspepsia together with a diagnostic algorithm was proposed. The adoption of grading systems for gastric cancer risk stratification, and modern image-enhancing endoscopy for the diagnosis of gastritis, were recommended. Treatment to eradicate H. pylori infection before preneoplastic changes develop, if feasible, was recommended to minimise the risk of more serious complications of the infection. Conclusions A global consensus for gastritis was developed for the first time, which will be the basis for an international classification system and for further research on the subject.

    Here, we report on a case of acute phlegmonous gastritis (PG) complicated by delayed perforation. A 51-year-old woman presented with severe abdominal pain and septic shock symptoms. A computed tomography scan showed diffuse thickening of the gastric wall and distention with peritoneal fluid. Although we did not find definite evidence of free air on the computed tomography (CT) scan, the patient's clinical condition suggested diffuse peritonitis requiring surgical intervention. Exploratory laparotomy revealed a thickened gastric wall with suppurative intraperitoneal fluid in which Streptococcus pyogenes grew. There was no evidence of gastric or duodenal perforation. No further operation was performed at that time. The patient was conservatively treated with antibiotics and proton pump inhibitor, and her condition improved. However, she experienced abdominal and flank pain again on postoperative day 10. CT and esophagogastroduodenoscopy showed a large gastric ulcer with perforation. Unfortunately, although the CT showed further improvement in the thickening of the stomach and the mucosal defect, the patient's condition did not recover until a week later, and an esophagogastroduodenoscopy taken on postoperative day 30 showed suspected gastric submucosal dissection. We performed total gastrectomy as a second operation, and the patient recovered without major complications. A pathological examination revealed a multifocal ulceration and necrosis from the mucosa to the serosa with perforation.

    Sixty-eight patients with various types of gastritis, 23 patients with normal stomachs, and four patients with other gastric diseases were examined in a prospective study to assess the sensitivity and specificity of single-contrast (SC) and double-contrast (DC) upper gastrointestinal examinations in the evaluation of gastritis. All patients underwent endoscopy with biopsy followed first by DC and then by SC radiography. The respective sensitivities of SC and DC radiography were 58% and 72% for all examinations and 59% and 77% for adequate examinations only. The respective specificities were 59% and 55% based on all examinations. Useful radiographic features included polypoid defects and erosions detected by both methods, abnormal folds and flattened margins detected by the SC technique, and narrowed lumen and crenulated margins detected by the DC technique. In 93% of all cases, the correct diagnosis was based on two or more of these radiographic features. According to this study, the radiographic sensitivity in the detection of gastritis is reliable only in cases of moderate-to-severe disease and only when based on findings of the DC examination. Neither SC nor DC radiography should be used as the primary screening method for patients with suspected gastritis, and the radiographic diagnosis should be restricted to the terms ''erosive'' or ''nonerosive gastritis.''

    Helicobacter pylori establishes a chronic infection in the human stomach, causing gastritis, peptic ulcer, or gastric cancer, and more severe diseases are associated with virulence genes such as the cag pathogenicity island (PAI). The aim of this work was to study gene content differences among H. pylori strains isolated from patients with different gastroduodenal diseases in a Mexican-Mestizo patient population. H. pylori isolates from 10 patients with nonatrophic gastritis, 10 patients with duodenal ulcer, and 9 patients with gastric cancer were studied. Multiple isolates from the same patient were analyzed by randomly amplified polymorphic DNA analysis, and strains with unique patterns were tested using whole-genome microarray-based comparative genomic hybridization (aCGH). We studied 42 isolates and found 1,319 genes present in all isolates, while 341 (20.5%) were variable genes. Among the variable genes, 127 (37%) were distributed within plasticity zones (PZs). The overall number of variable genes present in a given isolate was significantly lower for gastric cancer isolates. Thirty genes were significantly associated with nonatrophic gastritis, duodenal ulcer, or gastric cancer, 14 (46.6%) of which were within PZs and the cag PAI. Two genes (HP0674 and JHP0940) were absent in all gastric cancer isolates. Many of the disease-associated genes outside the PZs formed clusters, and some of these genes are regulated in response to acid or other environmental conditions. Validation of candidate genes identified by aCGH in a second patient cohort allowed the identification of novel H. pylori genes associated with gastric cancer or duodenal ulcer. These disease-associated genes may serve as biomarkers of the risk for severe gastroduodenal diseases. PMID:19237517

    Recent data report that the incidence of peptic ulcer is decreasing in the general population; conversely, the rates of gastric and duodenal ulcer hospitalization and mortality remain very high in older patients. Two major factors that might explain this epidemiological feature in the elderly population are the high prevalence of Helicobacter pylori infection and the increasing prescriptions of gastroduodenal damaging drugs, including NSAIDs and/or aspirin (acetylsalicylic acid). The main goals for treating peptic ulcer disease in old age are to reduce recurrence of the disease and to prevent complications, especially bleeding and perforation. The available treatments for peptic ulcer are essentially based on gastric acid suppression with antisecretory drugs and the eradication of H. pylori infection. The aim of this article is to report the available data on clinical efficacy and tolerability of peptic ulcer treatments in elderly patients and provide recommendations for their optimal use in this special population. Proton pump inhibitor (PPI)-based triple therapies for 7 days are highly effective for the cure of H. pylori-positive peptic ulcers as well as for reducing ulcer recurrence. Antisecretory drugs are also the treatment of choice for NSAID- or aspirin-related peptic ulcers and are useful as preventive therapy in chronic users of NSAIDs and low-dose aspirin as antiplatelet therapy. Antisecretory PPI therapy has a favourable tolerability profile in geriatric patients; however, monitoring is suggested in older patients with frequent pulmonary infections, gastrointestinal malabsorption, unexplained chronic diarrhoea, osteoporosis or those taking concomitant cytochrome P450 2C19-metabolized medications. The overall approach to the geriatric patient should include a comprehensive geriatric assessment that ensures multidimensional evaluation of the patient in order to better define the clinical risk of adverse outcomes in the older patient with peptic ulcer and

    The prevalence of duodenal ulceration in regions of developing countries with a stable diet is related to the staple food(s) in that diet. A higher prevalence occurs in areas where the diet is principally milled rice, refined wheat or maize, yams, cassava, sweet potato or green bananas, and a lower prevalence in areas where the staple diet is based on unrefined wheat or maize, soya, certain millets or certain pulses. Experiments using animal peptic ulcer models showed that the lipid fraction in foods from the staple diets of low prevalence areas gave protection against both gastric and duodenal ulceration, including ulceration due to non-steroidal anti-inflammatory drugs (NSAIDs), and also promoted healing of ulceration. The protective activity was found to lie in the phospholipid, sterol and sterol ester fractions of the lipid. Amongst individual phospholipids present in the phospholipid fraction, phosphatidyl ethanolamine (cephalin) and phosphatidyl choline (Lecithin) predominated. The sterol fraction showing activity contained β-sitosterol, stigmasterol and an unidentified isomer of β-sitosterol. The evidence shows that dietary phytosterols and phospholipids, both individually and in combination, have a protective effect on gastroduodenal mucosa. These findings may prove to be important in the prevention and management of duodenal and gastric ulceration including ulceration due to NSAIDs.

    Infectious mononucleosis is a self-limiting clinical syndrome caused by primary Epstein-Barr virus (EBV) infection. EBV-associated gastritis, however, has rarely been documented. We report a case of a 17-year-old woman who presented with fever, sore throat, and epigastric pain. Upper endoscopy revealed diffuse granular mucosae and elevated lesions in the stomach. Histologically, the biopsied mucosa was infiltrated by numerous atypical lymphocytes. From clinical, histopathologic, immunohistochemical, and in situ hybridization analyses, we diagnosed EBV-associated gastritis. Her symptoms spontaneously resolved, and follow-up endoscopy revealed improvement and no atypical lymphocytes. To prevent misdiagnosis and unnecessary treatment, the possibility of EBV-associated gastritis should be considered.

    Russell body gastritis is an unusual form of chronic gastritis characterized by the permeation of lamina propria by numerous plasma cells with eosinophilic cytoplasmic inclusions. Very few cases have been reported in the literature; the majority of which have shown Helicobacter Pylori (H. pylori) infection, thus suggesting a correlation between plasma cell presence and antigenic stimulation by H. pylori. We present a case of Russell body gastritis in a 78-year-old woman who was undergoing esophagogastroduodenoscopy for epigastric pain. Gastric biopsy of the gastroesophageal junction showed the presence of cells with periodic acid-Schiff-positive hyaline pink bodies. Giemsa staining for H. pylori infection was negative, as well as immunohistochemical detection. The cells with eosinophilic inclusions stained positive for CD138, CD79a, and κ and lambda light chains, which confirmed plasma cell origin. In particular, κ and lambda light chains showed a polyclonal origin and the patient was negative for immunological dyscrasia. The histological observations were confirmed by ultrastructural examination. The cases reported in the literature associated with H. pylori infection have shown regression of plasma cells after eradication of H. pylori. Nothing is known about the progression of H. pylori-negative cases. The unusual morphological appearance of this type of chronic gastritis should not be misinterpreted during routine examination, and it should be distinguished from other common forms of chronic gastritis. It is mandatory to exclude neoplastic diseases such as gastric carcinoma, lymphoma and plasmocytoma by immunohistochemistry and electron microscopy, which can help with differential diagnosis. The long-term effects of plasma cells hyperactivation are still unknown, because cases of gastric tumor that originated in patients affected by Russell body gastritis have not been described in the literature. We are of the opinion that these patients should be scheduled

    The determination of the level of secretory IgA by a method of radial immunodiffusion after Mancini in the gastric juice of 48 patients with chronic gastritis in correlation with the status of the gastric mucosa, the level of acidification and the phase of exacerbation has shown diagnostic potentialities of the method. The highest IgA level was detected in patients with "rearrangement" gastritis and in patients with sharply suppressed gastric secretion. In marked atrophy of the gastric mucosa IgA secretion was significantly lowered. The period of remission was attended by a decrease in IgA secretion as compared with the phase of exacerbation.

    The pathogenesis, incidence, complication rates, response to acid suppression and Helicobacter pylori (H. pylori) eradication therapy in peptic ulcer associated with chronic disease such as liver cirrhosis, chronic renal failure, diabetes mellitus, and critically ill conditions are different from those with general population, so that the management strategies also should be differentiated. The eradication of H. pylori are not so effective for preventing recurrence of peptic ulcer in liver cirrhosis patients as shown in general population, and conservative managements such as preventing deterioration of hepatic function and decrease in portal pressure are mandatory to reduce the risk of ulcer recurrence. The standard triple therapy for H. pylori eradication are as effective in chronic renal failure patients as in normal population, but the frequency of side effects of amoxicillin is higher in the patients not receiving dialysis therapy. Delay in eradication therapy until beginning of dialysis therapy or modification of eradication regimen should be considered in such cases. High prevalence of asymptomatic peptic ulcers and increased mortality in complicated peptic ulcer disease warrant regular endoscopic surveillance in diabetic patients, especially with angiopathy. The prolongation of duration of eradication therapy also should be considered in diabetic patients with angiopathic complication because of lower eradication rate with standard triple regimens as compared to normal population. Prophylactic acid suppressive therapy is highly recommended in critically ill patients with multiple risk factors. Herein, we propose evidence-based treatment guidelines for the management of peptic ulcer disease in special conditions based on literature review and experts opinion.

  7. Diagnostic and Treatment Approaches for Refractory Peptic Ulcers

    PubMed Central

    2015-01-01

    Refractory peptic ulcers are defined as ulcers that do not heal completely after 8 to 12 weeks of standard anti-secretory drug treatment. The most common causes of refractory ulcers are persistent Helicobacter pylori infection and use of nonsteroidal anti-inflammatory drugs (NSAIDs). Simultaneous use of two or more H. pylori diagnostic methods are recommended for increased sensitivity. Serologic tests may be useful for patients currently taking proton pump inhibitors (PPIs) or for suspected false negative results, as they are not affected by PPI use. NSAID use should be discontinued when possible. Platelet cyclooxygenase activity tests can confirm surreptitious use of NSAIDs or aspirin. Cigarette smoking can delay ulcer healing. Therefore, patients who smoke should be encouraged to quit. Zollinger-Ellison syndrome (ZES) is a rare but important cause of refractory gastroduodenal ulcers. Fasting plasma gastrin levels should be checked if ZES is suspected. If an ulcer is refractory despite a full course of standard PPI treatment, the dose should be doubled and administration of another type of PPI considered. PMID:26240800

    Helicobacter heilmannii-like organisms (HHLOs) are associated with mucosa-associated lymphoid tissue lymphoma and peptic ulcer. However, the sensitivity of diagnostic tests for HHLOs, such as rapid urease test (RUT), urea breath test (UBT) and blood antibody, is not high. Tightly coiled spiral microorganisms were found in the gastric mucosal biopsy specimen of a 48-year-old asymptomatic woman. Her findings were positive for RUT and UBT, but negative for blood antibody and stool antigen against H. pylori. A 7-day course of esomeprazole, amoxicillin and clarithromycin was administered, resulting in the successful eradication of the HHLOs. Analysis of the 16S rRNA and urease genes suggested a diagnosis of the HHLO H. suis. The sensitivity results of RUT, UBT, culture, blood antibody, immunohistochemistry and stool antigen were 40.0, 14.8, 0, 23.1, 40.0 and 0%, respectively. We report asymptomatic nodular gastritis due to an HHLO. Histological techniques, most likely with smears, are expected to be the most effective method for diagnosing infections by HHLOs, and genetic diagnosis by polymerase chain reaction can be very useful to identify the species of HHLOs.

    Chronic inflammation and infection are major risk factors for gastric carcinogenesis in adults. As chronic gastritis is common in Mexican children, diagnosis of Helicobacter pylori and other causes of gastritis are critical for the identification of children who would benefit from closer surveillance. Antral biopsies from 82 Mexican children (mean age, 8.3 ± 4.8 years) with chronic gastritis (36 H pylori+, 46 H pylori-) were examined for gastritis activity, atrophy, intestinal metaplasia (IM), and immunohistochemical expression of gastric carcinogenesis biomarkers caudal type homeobox 2 (CDX2), ephrin type-B receptor 4 (EphB4), matrix metalloproteinase 3 (MMP3), macrophage migration inhibitory factor (MIF), p53, β-catenin, and E-cadherin. Atrophy was diagnosed in 7 (9%) of 82, and IM, in 5 (6%) of 82 by routine histology, whereas 6 additional children (7%) (3 H pylori+) exhibited aberrant CDX2 expression without IM. Significant positive correlations were seen between EphB4, MMP3, and MIF (P<.0001). Atrophy and follicular pathology were more frequent in H pylori+ biopsies (P<.0001), whereas IM and CDX2 expression showed no significant correlation with H pylori status. Antral biopsies demonstrating atrophy, IM, and/or aberrant CDX2 expression were seen in 21.95% (18/82) of the children, potentially identifying those who would benefit from closer surveillance and preventive dietary strategies. Biomarkers CDX2, EphB4, MMP3, and MIF may be useful in the workup of pediatric gastritis.

    Seven illustrative cases of gastritis of the herniated stomach in patients with sliding esophageal hiatus hernia are reported. Five had superficial gastritis (three mild, one moderate and one severe); two had atrophic gastritis. Gastritis was present in two patients whose mucosa appeared normal at esophagoscopy. Interstitial hemorrhage into the lamina propria was present in four of the seven biopsy specimens. The possibility that interstitial hemorrhage may be related to the development of gastric erosions is considered. The pathogenesis of this form of gastritis is discussed.

    Over a 10-year period in a busy paediatric surgical unit, six children were operated upon for peptic ulcer disease, four of whom presented with complications (pyloric stenosis, two; perforation, one; bleeding, one). Truncal vagotomy with a drainage procedure was the operation of choice in five of the children in whom there were no complications. One child suspected of having Zollinger-Ellison syndrome had recurrence of symptoms. Symptoms of peptic ulcer disease in children are non-specific, and in our environment such symptoms are frequently considered to be due to parasitic infestation. Barium meal is not very sensitive in diagnosis in children, and the relative lack of availability of endoscopic services limits pre-operative diagnosis. It is suggested that peptic ulcer disease be considered in children who have persistent or recurrent abdominal pain of obscure aetiology.

    We carried out a review of the literature on Campylobacter pylori-associated gastritis and nonulcer dyspepsia (NUD) to determine whether or not symptoms related to these conditions can be measured reliably and whether or not any study to date has shown that treatment alters symptoms. Search strategies consisted of online Medline searching, a forward search of three articles using the Science Citation Index, a manual search of five gastroenterological journals, and a fully recursive search of cited references. Inclusion and quality criteria were applied to all retrieved studies. Nine of 23 studies did not fulfill the inclusion criteria. Of the 14 studies analyzed, two measured symptoms reliably. Neither showed a therapeutic benefit on symptoms. The difficulties encountered in conducting such studies and the methods of recording symptoms reliably are discussed. We conclude that to date, no treatment is of proven benefit in the relief of symptoms associated with C. pylori gastritis and NUD.

    Although the significance of focally enhanced gastritis (FEG) as a marker of Crohn disease (CD) in adults has been contested, several studies suggest that it may be more specific of CD in pediatric patients. This study describes the detailed histologic features of FEG in pediatric inflammatory bowel disease (IBD) and clarifies its association with CD. A series of 119 consecutive newly diagnosed IBD patients (62 CD cases, 57 ulcerative colitis [UC] cases) with upper and lower gastrointestinal biopsies were evaluated. The histology of the gastric biopsies was reviewed blinded to final diagnoses and compared with age-matched healthy controls (n=66). FEG was present in 43% of IBD patients (CD 55% vs. UC 30%, P=0.0092) and in 5% of controls. Among CD patients, FEG was more common in younger patients (73% in children aged 10 y and below, 43% in children above 10 y of age, P=0.0358), with the peak in the 5- to 10-year age group (80%). The total number of glands involved in each FEG focus was higher in UC (6.4±5.1 glands) than in CD (4.0±3.0 glands, P=0.0409). Amongst the CD cohort, patients with FEG were more likely than those without FEG to have active ileitis (79% vs. 40%, P=0.0128) and granulomas elsewhere in the gastrointestinal tract (82% vs. 43%, P=0.0016). There was no correlation between FEG and other gastrointestinal findings of UC. We demonstrate that differences in FEG seen in pediatric CD and UC relate to not only their frequencies but also the morphology and relationship with other gastrointestinal lesions. Further, FEG is associated with disease activity and the presence of granulomas in pediatric CD.

  15. Peptic ulceration may be a hormonal deficiency disease.

    PubMed

    Love, Jack W

    2008-01-01

    Evidence is reviewed that Helicobacter pylori infection may cause a deficiency of the hormone secretin that allows peptic ulcer disease to develop by impairing the body's defenses to gastric acid. Secretin is released into the circulation from the S-cells of the duodenal crypts in response to gastric acid entering the duodenum. Once in the circulation, secretin has five well-documented effects that protect the upper intestine from gastric acid: it stimulates secretion of bicarbonate rich exocrine pancreatic juice; it stimulates secretion of alkaline bile; it stimulates secretion of alkaline mucus from the duodenal submucosal glands of Brunner; it inhibits the humoral phase of gastric secretion; and it inhibits gastric motility, thereby delaying gastric emptying. Impaired secretin release and reduced duodenal S-cells have been documented in peptic ulcer patients compared with control patients. Clinical evidence that patients with H. pylori infection and peptic ulceration have increased gastric secretion and motility and decreased duodenal bicarbonate response to gastric acid, all of which normalize after eradication of the infection, could be explained by reversible impairment of the secretin mechanism. Gastric metaplasia in the duodenum with H. pylori infection is known to reduce the S-cell population. The fact that not all patients with H. pylori infection develop peptic ulceration suggests that degree of secretin deficiency determined by extent of the infection must reach a critical level for peptic ulceration to occur. Peptic ulceration may be a hormonal deficiency disease, a result of secretin deficiency caused by H. pylori infection. It may be the first example of a specific hormonal deficiency disease caused by a specific bacterial infection.

    The complaints and dietary habits of sixteen patients with gastritis and fourteen with undefined abdominal pain were studied by recording method. The results showed that the symptoms of the patients with gastritis and undefined abdominal pain were similar and mostly postprandial and they can be regarded as local (abdominal pain, meteorism, discomfort and heartburn) and/or general (sweating, nausea and faintness). The patients have variations of the symptomatic and asymptomatic periods. The symptomatic patients with gastritis have significantly higher number of daily meals than the asymptomatic patients with gastritis. The daily intake of food, energy and nutrients are low especially in the symptomatic patients with gastritis. It is concluded that the symptoms experienced by the patients with gastritis or undefined abdominal pain are related to the eating so that the daily dietary habits are disturbed. The produced a low intake of food, energy and nutrients especially in the patients with symptomatic gastritis.

    Investigation of the bypassed stomach in patients with suspected peptic ulcer disease presents a major challenge to bariatric surgeons. Various methods have been suggested for visualization of the duodenum and bypassed stomach. These include endoscopy via percutaneous gastrostomy access, retrograde endoscopy and virtual gastroscopy using CT scan. We present a case of peptic ulcer bleeding diagnosed with the help of conventional CT scan. To the best of our knowledge, this is the second such case reported in the literature and the first in the bariatric population.

    Peptic ulcer disease is one of the most commonly encountered diseases in gastroenterology clinics. After the discovery of Helicobacter pylori by Warren and Marshall, it has been identified as the most important cause of peptic ulcer. Eradication of H. pylori markedly reduces the post-treatment recurrence rate of peptic ulcer. However, as human populations age, the incidence of cardiovascular and musculoskeletal diseases increases and consequent use of aspirin and non-steroidal anti-in-flammatory drugs increases. Thus causes and presenting patterns of peptic ulcer have changed. In this review, I describe new diagnostic and therapeutic strategies for peptic ulcer disease and explore future perspectives.

    Abstract Background: Helicobacter pylori (H. pylori) infection of the human stomach regularly leads to chronic gastric inflammation. The cytokine gene interleukin (IL)-1β has been implicated in influencing the pathology of inflammation induced by H. pylori infection. Currently, several studies have been carried out to investigate the association of IL-1β-511 (rs16944) and IL-1β-31 (rs1143627) polymorphisms with gastritis risk; however, the results are inconsistent and inconclusive. To assess the effect of IL-1β polymorphisms on gastritis susceptibility, we conducted a meta-analysis. Methods: Up to March 15, 2016, 2205 cases and 2289 controls were collected from 12 published case–control studies. Summarized odds ratios and corresponding 95% confidence intervals (CIs) for IL-1β-511 and IL-1β-31 polymorphisms and gastritis risk were estimated using fixed- or random-effects models when appropriate. Heterogeneity was assessed by chi-squared-based Q-statistic test, and the sources of heterogeneity were explored by subgroup analyses and logistic meta-regression analyses. Publication bias was evaluated by Begg funnel plot and Egger test. Sensitivity analyses were also performed. Results: The results provided evidences that the single nucleotide polymorphisms (SNPs) in IL-1β-31 might be associated with the gastritis risk, especially in the Caucasian population, while SNPs in the IL-1β-511 might not be. Conclusion: Our studies may be helpful in supplementing the disease monitoring of gastritis in the future, and additional studies to determine the exact molecular mechanisms might inspire interventions to protect the susceptible subgroups.

    More than 50% of the world population is infected with Helicobacter pylori (H. pylori). The bacterium highly links to peptic ulcer diseases and duodenal ulcer, which was classified as a group I carcinogen in 1994 by the WHO. The pathogenesis of H. pylori is contributed by its virulence factors including urease, flagella, vacuolating cytotoxin A (VacA), cytotoxin-associated gene antigen (Cag A), and others. Of those virulence factors, VacA and CagA play the key roles. Infection with H. pylori vacA-positive strains can lead to vacuolation and apoptosis, whereas infection with cagA-positive strains might result in severe gastric inflammation and gastric cancer. Numerous medicinal plants have been reported for their anti-H. pylori activity, and the relevant active compounds including polyphenols, flavonoids, quinones, coumarins, terpenoids, and alkaloids have been studied. The anti-H. pylori action mechanisms, including inhibition of enzymatic (urease, DNA gyrase, dihydrofolate reductase, N-acetyltransferase, and myeloperoxidase) and adhesive activities, high redox potential, and hydrophilic/hydrophobic natures of compounds, have also been discussed in detail. H. pylori-induced gastric inflammation may progress to superficial gastritis, atrophic gastritis, and finally gastric cancer. Many natural products have anti-H. pylori-induced inflammation activity and the relevant mechanisms include suppression of nuclear factor-κB and mitogen-activated protein kinase pathway activation and inhibition of oxidative stress. Anti-H. pylori induced gastric inflammatory effects of plant products, including quercetin, apigenin, carotenoids-rich algae, tea product, garlic extract, apple peel polyphenol, and finger-root extract, have been documented. In conclusion, many medicinal plant products possess anti-H. pylori activity as well as an anti-H. pylori-induced gastric inflammatory effect. Those plant products have showed great potential as pharmaceutical candidates for H. pylori

    Therapeutic gastric irradiation has been used to reduce peptic juice secretion in patients with peptic ulcer disease. Between 1937 and 1968 a total of 2049 patients received such therapy at the University of Chicago. Three of these patients are known to have developed sarcomas in the field of radiation. Two gastric leiomyosarcomas of the stomach were diagnosed 26 and 14 years after treatment and a malignant fibrous histiocytoma of the anterior chest wall was removed six years after gastric irradiation. Of 743 peptic ulcer patients treated without irradiation and constituted as a control group for the study of therapeutic gastric radiation, none is known to have developed sarcoma. As the incidence of sarcoma in these patient groups is known only from the tumor registry of the University of Chicago, other cases of sarcoma may exist in the groups. While an increased incidence of sarcoma has not been proven to occur in patients who received therapeutic gastric irradiation for peptic ulcer disease, the possibility of such a risk should be borne in mind by physicians caring for such patients.

    Gastric urease was studied isotopically in 230 patients with biopsy-proven normal mucosa or chronic gastritis, including 59 patients with ulcer disease. Carbon-14-urea was given in 25 ml of water without substrate carrier or nutrient-dense meal, and breath samples were collected over a 60-min period. The amount of 14CO2 excreted at 10 min was independent of the rate of gastric emptying and was not quantitatively influenced by the buccal urease activity. The 10-min 14CO2 values discriminated well between Helicobacter pylori positive and negative patients (94% sensitivity, 89% specificity) and correlated with the number of organisms assessed by histology. The test was a good predictor of chronic gastritis (95% sensitivity and 96% specificity), and a quantitative relationship was observed between 14CO2 values and the severity and activity of the gastritis. In H. pylori positive patients, breath 14CO2 was found to be similar in patients with and without ulcer disease, suggesting that the number of bacteria is not a determining factor for the onset of ulceration.

    Clostridium septicum is the causative agent of histotoxic infections, including malignant edema and braxy (necrotizing abomasitis) in several animal species. The carcass of a 2-year-old, female New Zealand white rabbit with a history of acute depression and obtundation followed by death was received at the California Animal Health and Food Safety Laboratory System (San Bernardino, California) for necropsy and diagnostic workup. No gross lesions were detected at necropsy. Microscopically, there was moderate to severe, multifocal fibrinonecrotizing, transmural gastritis with numerous intralesional Gram-positive, sporulated rods, and disseminated thrombosis of the brain, lungs, heart, and liver, with occasional intravascular rods. The rods observed within the gastric wall and thrombi in the stomach and lung were positive for C. septicum by immunohistochemical staining. However, this microorganism was not isolated from stomach content. Clostridium septicum should be included in the list of possible etiologies of gastritis in rabbits.

    The influential roles of antibiotic prophylaxis on cirrhotic patients with peptic ulcer bleeding are still not well documented. The purpose of this study is to clarify these influential roles and to identify the risk factors associated with rebleeding, bacterial infection and in-hospital mortality. A cross-sectional, chart review study was conducted on 210 cirrhotic patients with acute peptic ulcer hemorrhage who underwent therapeutic endoscopic procedures. Patients were divided into group A (with prophylactic intravenous ceftriaxone, n = 74) and group B (without antibiotics, n = 136). The outcomes were length of hospital days, prevention of infection, rebleeding rate and in-hospital mortality. Our results showed that more patients suffered from rebleeding and infection in group B than group A (31.6% vs. 5.4%; p<0.001 and 25% vs. 10.8%; p = 0.014 respectively). The risk factors for rebleeding were active alcoholism, unit of blood transfusion, Rockall score, model for end-stage liver disease score and antibiotic prophylaxis. The risk factors for infection were active alcoholism, Child-Pugh C, Rockall score and antibiotic prophylaxis. Rockall score was the predictive factor for in-hospital mortality. In conclusions, antibiotic prophylaxis in cirrhotic patients after endoscopic interventions for acute peptic ulcer hemorrhage reduced infections and rebleeding rate but not in-hospital mortality. Rockall score was the predictive factor of in-hospital mortality.

    A 3-year-old, neutered male Tiffany cat was presented to the Animal Health Trust for investigation of pyrexia and a gastric lesion. Radiography and ultrasound showed severe thickening of the gastric wall and regional lymphadenopathy. There was altered gastric wall layering, predominately due to muscularis thickening. Histopathology confirmed eosinophilic fibrosing gastritis. The cat also had evidence of generalised Toxoplasma gondii infection, which may have been responsible for the gastric changes.

    One extremely rare complication of chemotherapy for hematologic malignancies that is burdened with a high mortality rate (50%-80%) is necrotizing gastritis and gastric gangrene as result of poor clinical outcome of neutropenic gastritis (NG). We present a unique case of a neutropenic patient with necrotizing full thickness gastritis due to bacterial and fungal infection. Up to date only few such cases have been reported in world literature. A 28-year-old patient was subjected to dose-escalated BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, prednisone), (chemotherapy regimen) for Hodgkin lymphoma. In neutropenic patient abdominal pain, bleeding from the alimentary tract was observed. Hemorrhagic gastritis was recognized at endoscopy and CT demonstrated marked gastric wall thickness. Following NG diagnosis intensive treatment was initiated. On day 2 the patient's condition deteriorated (septic shock, multiple organ failure). Repeat endoscopy revealed gastric necrosis and laparotomy was performed. As consequence of cardiac arrest and cardiopulmonary resuscitation the surgical procedure was limited to total gastrectomy, feeding jejustomy and esophageal drainage through nasoesophageal catherization. Roux-loop esophagojejunostomy was performed on day 22 and supplemented 4 days later by endoscopic placement of covered self-expandable stent due to anastomosis leak. The procedure proved successful and oral feeding was well-tolerated. The patient was discharged in 32 days following recognition of gastric necrosis. Chemotherapy complications in neutropenic patients are life-threatening conditions. Immediate pharmacological treatment usually leads to improvement. Surgical management usually the resection of necrotic zones is restricted to cases of poor prognosis or deterioration of patient's condition and complications.

    Collagenous gastritis is a rare condition defined histologically by a superficial subepithelial collagen layer. This study further characterizes the morphologic spectrum of collagenous gastritis by evaluating a multi-institutional series of 40 patients (26 female and 14 male). The median age at onset was 16 years (range 3-89 years), including 24 patients (60%) under age 18. Twelve patients (30%) had associated celiac disease, collagenous sprue, or collagenous colitis. Hematoxylin and eosin slides were reviewed in biopsies from all patients and tenascin, gastrin, eotaxin, and IgG4/IgG immunohistochemical stains were applied to a subset. The distribution of subepithelial collagen favored the body/fundus in pediatric patients and the antrum in adults. There were increased surface intraepithelial lymphocytes (>25 lymphocytes/100 epithelial cells) in five patients. Three of these patients had associated celiac and/or collagenous sprue/colitis, while the remaining two had increased duodenal lymphocytosis without specific etiology. An eosinophil-rich pattern (>30 eosinophils/high power field) was seen in 21/40 (52%) patients. Seven patients' biopsies demonstrated atrophy of the gastric corpus mucosa. Tenascin immunohistochemistry highlighted the subepithelial collagen in all 21 specimens evaluated and was a more sensitive method of collagen detection in biopsies from two patients with subtle subepithelial collagen. No increased eotaxin expression was identified in 16 specimens evaluated. One of the twenty-three biopsies tested had increased IgG4-positive cells (100/high power field) with an IgG4/IgG ratio of 55%. In summary, collagenous gastritis presents three distinct histologic patterns including a lymphocytic gastritis-like pattern, an eosinophil-rich pattern, and an atrophic pattern. Eotaxin and IgG4 were not elevated enough to implicate these pathways in the pathogenesis. Tenascin immunohistochemistry can be used as a sensitive method of collagen detection.

    The effects of ceremide analogues on esophagitis and gastritis in rats were examined. Gastritis induced by indomethacin was significantly reduced after CY3325 and CY3723 treatment, whereas other analogues had no effect. The amount of malondialdehyde in gastritis was significantly reduced by CY3325 or CY 3723. CY3325 or CY 3723 decreased the glutathione levels in gastritis. The myeloperoxidase level in gastritis is increased, and its increment was decreased by CY3325 and CY3723. In reflux esophagitis, the ulceration was decreased by CY3325, CY3723. The gastric volume and acid output are reduced, whereas the pH value is increased by CY3325 or CY3723 after esophagitis. These results suggest that ceramide analogues, CY3325 and CY3723, can prevent the development of gastritis and reflux esophagitis in rats.

    Russell body gastritis was first defined in 1998, but not many cases have been reported since then. The exact causes and process of this condition are unknown yet; however, considering the reported cases, it has been highly suggested to have correlation with Helicobacter pylori infection. Russell body gastritis has a non-specific clinical presentation of gastritis such as gastric mucosal edema in the macroscopic view. It can be mistaken as xanthoma, signet ring cell carcinoma, or a malignant lymphoma including mucosa-associated lymphoid tissue lymphoma and plasmocytoma. Russell body gastritis features polyclonal immunoglobulin and is differentiated from Mott cancer, of which immune globulin has monoclonal aspect. Authors report here two cases of Russell body gastritis with examined endoscopic findings as well as a review of related literature on the association of all reported cases of Russell body gastritis with H. pylori infection.

    The paper presents the results of observations concerning the effect of cigarette smoking on the prevalence of peptic ulcer among 6,512 rural inhabitants aged 20-64, selected by two-stage sampling. Of these, 2,506 (38.6%) were regular smokers. In order to determine precisely the negative effect of smoking on the human body the nicotinic index was used (N.I.), calculated by multiplying the number of cigarettes smoked daily by the period of smoking (years). The three-stage scale of the nicotinic index was applied: I degrees - N.I. < 100, II degrees - N.I. = 100-300, III degrees - N.I. > 300. The mean value of the nicotinic index calculated for the total number of smokers in the study was 290.3. A statistically significant higher N.I. was observed in patients with peptic ulcer - 432.5, compared to patients with other diseases - 337.2, and healthy individuals - 203.3. Among patients with peptic ulcer the highest percentage of people with N.I. > 300 was noted (59.0%), compared to patients with other diseases (42.9%) and those who were healthy (22. 6%). The differences observed between patients with peptic ulcer and those of the remaining groups were highly statistically significant (p<0.001). The percentage of people with the lowest value of the nicotinic index (N.I.<100) in individual groups was: in patients with peptic ulcer - 13.5% (the lowest), among patients with other diseases - 25.0%, in the group of healthy individuals - 38.5% (the highest). An increase was noted in the incidence of peptic ulcer with the value of the nicotinic index. Peptic ulcer occurred in 3.8% of patients with N.I. < 100, in 6.4% of those with N.I. = 100-300, and in 13.2% of patients with N.I. > 300. An increase in the percentage of patients with the nicotinic index was observed irrespective of the site of ulcer. It became most evident among patients who underwent surgical treatment due to peptic ulcer, where the highest value of the nicotinic index (N.I. > 300) was noted in 79.5%, in

    Caveolin-1 (Cav1) is a scaffold protein and pathogen receptor in the mucosa of the gastrointestinal tract. Chronic infection of gastric epithelial cells by Helicobacter pylori (H. pylori) is a major risk factor for human gastric cancer (GC) where Cav1 is frequently down-regulated. However, the function of Cav1 in H. pylori infection and pathogenesis of GC remained unknown. We show here that Cav1-deficient mice, infected for 11 months with the CagA-delivery deficient H. pylori strain SS1, developed more severe gastritis and tissue damage, including loss of parietal cells and foveolar hyperplasia, and displayed lower colonisation of the gastric mucosa than wild-type B6129 littermates. Cav1-null mice showed enhanced infiltration of macrophages and B-cells and secretion of chemokines (RANTES) but had reduced levels of CD25+ regulatory T-cells. Cav1-deficient human GC cells (AGS), infected with the CagA-delivery proficient H. pylori strain G27, were more sensitive to CagA-related cytoskeletal stress morphologies (“humming bird”) compared to AGS cells stably transfected with Cav1 (AGS/Cav1). Infection of AGS/Cav1 cells triggered the recruitment of p120 RhoGTPase-activating protein/deleted in liver cancer-1 (p120RhoGAP/DLC1) to Cav1 and counteracted CagA-induced cytoskeletal rearrangements. In human GC cell lines (MKN45, N87) and mouse stomach tissue, H. pylori down-regulated endogenous expression of Cav1 independently of CagA. Mechanistically, H. pylori activated sterol-responsive element-binding protein-1 (SREBP1) to repress transcription of the human Cav1 gene from sterol-responsive elements (SREs) in the proximal Cav1 promoter. These data suggested a protective role of Cav1 against H. pylori-induced inflammation and tissue damage. We propose that H. pylori exploits down-regulation of Cav1 to subvert the host's immune response and to promote signalling of its virulence factors in host cells. PMID:23592983

    The gastric pathogen Helicobacter pylori utilizes molecular hydrogen (H2) as a respiratory substrate during colonization in the gastric mucosa. However, the link between molecular H2 and the pathogenesis of peptic-ulcer disease (PUD) and non-ulcerous dyspepsia (NUD) by the enzymatic activity of H. pylori still remains mostly unknown. Here we provide evidence that breath H2 excretion profiles are distinctly altered by the enzymatic activity of H. pylori for individuals with NUD and PUD. We subsequently unravelled the potential molecular mechanisms responsible for the alteration of H2 in exhaled breath in association with peptic ulcers, encompassing both gastric and duodenal ulcers, along with NUD. We also established that carbon-isotopic fractionations in the acid-mediated bacterial environment regulated by bacterial urease activity cannot discriminate the actual disease state i.e. whether it is peptic ulcer or NUD. However, our findings illuminate the unusual molecular H2 in breath that can track the precise evolution of PUD and NUD, even after the eradication of H. pylori infection. This deepens our understanding of the pathophysiology of PUD and NUD, reveals non-invasively the actual disease state in real-time and thus offers a novel and robust new-generation strategy for treating peptic-ulcer disease together with non-ulcer related complications even when the existing (13)C-urea breath test ((13)C-UBT) fails to diagnose.

    Flow cytometric cell cycle analysis was recorded in gastric biopsy specimens from patients with normal gastric mucosa (GM), superficial gastritis (SG) and chronic atrophic gastritis (CAG). Cell-cycle analysis showed significantly higher percentages of cells in S- and S+G2/M-phase in CAG than in SG and normal GM (P < 0.0001). Moreover, CAG with severe or moderate atrophy showed significantly higher percentages of cells in S-phase (P < 0.05) and S+G2/M-phase (P < 0.02) than CAG with mild atrophy in antrum. In fundus, even if this increase was observed, it did not reach statistical significance. Consideration of concomitant pathologic findings such as oesophagite, gastric or duodenal ulcer, duodenite or benign polyp allowed a better differentiation of CAG both in antrum and in fundus. Significantly higher S-phase was observed in CAG with severe or moderate atrophy than in CAG with mild atrophy (P < 0.05). No statistically significant results were observed in patients with normal gastric mucosa or chronic gastritis and a concomitant pathologic finding.

    Helicobacter pylori eradication rate following standard triple therapy is decreasing. Identification of predictive factors of therapy success would be useful for H. pylori management in clinical practice. This study aimed to evaluate the role of different gastritis patterns on the efficacy of the currently suggested 14-day triple therapy regimen. One-hundred and seventeen, consecutive, non-ulcer dyspeptic patients, with H. pylori infection diagnosed at endoscopy, were enrolled. All patients received a 14-day, triple therapy with lansoprazole 30 mg, clarithromycin 500 mg and amoxicillin 1 g, all given twice daily. Bacterial eradication was assessed with (13)C-urea breath test 4-6 weeks after completion of therapy. H. pylori infection was cured in 70.1% at ITT analysis and 83.7% at PP analysis. The eradication rate tended to be lower in patients with corpus-predominant gastritis as compared to those with antral-predominant gastritis at both ITT (66.1 vs 74.5%) and PP (80.4 vs 87.2%) analyses. The multivariate analysis failed to identify factors associated with therapy success. However, 14-day triple therapy does not achieve acceptable H. pylori cure rate in Italy, and should be not recommended in clinical practice.

    The story of gastric acid secretion began with early ideas on gastric secretion (Spallanzani and de Réaumur, 17th century) and with first descriptions of food digestion (Dupuytren and Bichat, Beaumont, early 18th century), followed by proof that gastric juice contained acid (Prout, early 18th century). The research continued with first descriptions of gastric glands as the source of gastric acid and its changes upon digestive stimulus (Purkinje and Golgi, mid and late 19th century). The theory of 'nervism' - the neuro-reflex stimulation of gastric secretion by vagal nerve (Pavlov, early 20th century) was contrasted by a histamine-mediated concept of gastric secretion (Popielski and Code, mid 20th century). Thus, gastric acid and pepsin (Schwann, early 19th century) were found to be essential for food digestion and studies also pointed to histamine, being the most potent final common chemostimulator of oxyntic cells. The discoveries in etiopathogenesis of mucosal injury were marked by the famous dictum: 'No acid, no ulcer' ('Ohne saueren Magensaft kein peptisches Geschwür', Schwarz, 1910) that later induced the term of 'mucosal defense' and the notion that the breaking of 'gastric mucosal barrier' represents the initial step in the process of mucosal injury (Davenport, Code and Scholer, mid 20th century). The prostaglandins were shown to influence all major components of gastric mucosal barrier, described with the term 'cytoprotection' (Vane, Robert and Jacobson, 1970s). Beginning in the latter half of 19th century, the studies on gastric bacteriology that followed enabled the discovery of association between Campylobacter (Helicobacter) pylori and peptic ulcers (Warren and Marshall, 1980s) that led to worldwide major interventions in treating peptic ulcer disease. The surgical approach to peptic ulcer had been outlined by resection procedures (Billroth, Pean, Moynihan, late 19 century) and vagotomy, with or without drainage procedures (Jaboulay, Latarjet

    Infectious mononucleosis is Epstein-Barr virus (EBV) inducing a self-limiting clinical syndrome characterized by fever, sore throat, hepatosplenomegaly, and generalized lymphadenopathy. Gastrointestinal symptoms of EBV infection are nonspecific and occur rarely. EBV inducing acute gastrointestinal pathology is poorly recognized without suspicion. Careful consideration is needed to diagnose gastric involvement of EBV infection including gastric lymphoma, gastric cancer, and gastritis. A few recent cases of gastritis associated with EBV infection have been reported in adolescents and adults. However, there is no report of EBV-associated gastritis in early childhood. We experienced a rare case of 4-year-old girl with EBV gastritis confirmed by in situ hybridization. PMID:28018450

    Helicobacter pylori (HP) is associated with chronic gastritis and gastric cancer, and more than half of the world's population is chronically infected. The aim of this retrospective study was to investigate whether an irregular meal pattern is associated with increased risk of gastritis and HP infection. The study involved 323 subjects, divided into three groups as follows: subjects with HP infection and gastritis, subjects with gastritis, and a control group. Subjects were interviewed on eating habits and meal timing. Multivariate logistic regression was used to compare groups. Adjusted odds ratios (OR) were derived controlling for gender, age, stress, and probiotic consumption. Subjects who deviated from their regular meals by 2 hours or more had a significantly higher incidence of HP infection with gastritis (adjusted OR = 13.3; 95% CI 5.3-33.3; P < 0.001) and gastritis (adjusted OR = 6.1; 95% CI 2.5-15.0; P < 0.001). Subjects who deviated their meals by 2 hours or more, twice or more per week, had an adjusted OR of 6.3 and 3.5 of acquiring HP infection with gastritis (95% CI 2.6-15.2; P < 0.001) and gastritis (95% CI 1.5-8.5; P < 0.001), respectively. Frequent deviation in meal timing over a prolonged period appears associated with increased risk of developing HP infection and gastritis.

    Peptic ulcer bleeding is an internal medical emergency. Endoscopic hemostasis has been shown to improve the survival rate of patients with peptic ulcer bleeding. Although the established hemostatic modalities, including injection, thermal therapy, and mechanical therapy, are effective in controlling peptic ulcer bleeding, hemostasis can be difficult to achieve in some cases. As a result, recent, new endoscopic hemostatic modalities, including over-the-scope clips, topical hemostatic sprays, and endoscopic ultrasonography-guided angiotherapy, have been developed.

    Acute upper gastrointestinal bleeding is a common medical emergency worldwide, a major cause of which are bleeding peptic ulcers. Endoscopic treatment and acid suppression with proton-pump inhibitors are cornerstones in the management of the disease, and both treatments have been shown to reduce mortality. The role of emergency surgery continues to diminish. In specialised centres, radiological intervention is increasingly used in patients with severe and recurrent bleeding who do not respond to endoscopic treatment. Despite these advances, mortality from the disorder has remained at around 10%. The disease often occurs in elderly patients with frequent comorbidities who use antiplatelet agents, non-steroidal anti-inflammatory drugs, and anticoagulants. The management of such patients, especially those at high cardiothrombotic risk who are on anticoagulants, is a challenge for clinicians. We summarise the published scientific literature about the management of patients with bleeding peptic ulcers, identify directions for future clinical research, and suggest how mortality can be reduced.

    The aim of this study was to evaluate the participation of polymorphism at position C421A and mRNA expression of the ABCG2 gene in the development of peptic ulcers, which is a very common and severe disease. ABCG2, encoded by the ABCG2 gene, has been found inter alia in the gastrointestinal tract, where it plays a protective role eliminating xenobiotics from cells into the extracellular environment. The materials for the study were biopsies of gastric mucosa taken during a routine endoscopy. For genotyping by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) at position C421A, DNA was isolated from 201 samples, while for the mRNA expression level by real-time PCR, RNA was isolated from 60 patients. The control group of healthy individuals consisted of 97 blood donors. The dominant genotype in the group of peptic ulcer patients and healthy individuals was homozygous CC. No statistically significant differences between healthy individuals and the whole group of peptic ulcer patients and, likewise, between the subgroups of peptic ulcer patients (infected and uninfected with Helicobacter pylori) were found. ABCG2 expression relative to GAPDH expression was found in 38 of the 60 gastric mucosa samples. The expression level of the gene varies greatly among cases. The statistically significant differences between the intensity (p = 0.0375) of H. pylori infection and ABCG2 gene expression have been shown. It was observed that the more intense the infection, the higher the level of ABCG2 expression.

    Cytochemical and autoradiographic studies in Wistar rats [Crl:(WI)BR] show that cisplatin treatment (9 mg/kg) inhibits the release of acetylcholine from the axonal endings of the stomach smooth muscle resulting in bloating of the stomach and ulceration. Cisplatin also induces corticosteroid release from the adrenal gland stimulating peptic ulceration. Vagotomy helps ameliorate the effect but not eliminate it. Calcium supplementation restores normal neuromuscular function to gastric smooth muscle, thereby eliminating the gastro-intestinal toxicity due to cisplatin.

    Heartburn, reflux and epigastric pain are frequently encountered symptoms in primary care medicine. Acid peptic diseases such as peptic ulcer and gastrointestinal reflux disease have a high prevalence, can have important impact on patient quality of life and represent a considerable health care cost. Proton pump inhibitors (PPIs) are the most potent pharmacological inhibitors of gastric acid secretion currently available and are the mainstay medical therapy for acid peptic diseases. This review summarizes current evidence on treatment of acid-peptic diseases with proton pump inhibitors and provides primary care clinicians with best practice guidelines for optimal use of these drugs.

    Previous work on a factor in the blood of patients with peptic ulcer which contracts smooth muscle was confirmed and the work extended to investigation of the activity of blood fractions. Whole heparinized blood and its fractions were tested on a strip of guinea pig ileum and height of contraction and latent period were used as criteria of activity. Whole heparinized blood of ulcer patients had significantly higher activity than that of normal controls. Differences between the fractions of ulcer patients and controls were less significant. With the lysed buffy coat, however, while the differences between the height of contraction between the groups did not differ statistically, the speed of the reaction (shorter latent period) was significantly greater in the ulcer patients. The cellular alterations causing this response are unknown.

    Chronic gastritis has a high incidence in adults, causing progressive destruction of glandular structures, favoring the development of gastric atrophy. The association of chronic gastritis with intestinal type metaplasia of gastric mucosa has a poor outcome as intestinal metaplasia is regarded as a precancerous lesion. Metaplasia is common in patients with Helicobacter pylori infection and also heavy smokers. The aim of our study was to evaluate the relationship between chronic gastritis and intestinal metaplasia. The study was conducted on a total of 1218 patients, aged between 5 and 90 years, who presented for dyspeptic disorders in the period 2007-2010 and were examined clinically and endoscopically. During the gastroscopic examination, fragments of gastric mucosa were collected for the histopathological study and for highlighting the H. pylori infection. For the histopathological study, the Hematoxylin-Eosin and PAS-Alcian Blue stains were performed, while for the immunohistochemical study the anti-TAG72 and anti-PCNA antibodies were used. A diagnosis of gastritis was established in 615 patients, representing approximately 50.5% of all cases. Most cases with gastritis were found in people of middle age. Gastritis was present in almost all age groups, from teenagers to the elders. Of the 615 cases of gastritis, urease test was positive in 353 patients, representing approximately 57.40% of all patients with gastritis. Histopathological examination identified the presence of intestinal metaplasia in 61.60% of patients with chronic gastritis, mostly complete metaplasia. PCNA immunohistochemistry revealed that cell proliferation processes are intensified in intestinal metaplasia. This study highlights the importance of chronic gastritis, intestinal metaplasia, and H. pylori infection in the etiopathogeny of gastric cancer.

    The pathophysiology of gastritis involves an imbalance between gastric acid attack and mucosal defence. In addition, the gastric mucosal injury results in adenosine triphosphate (ATP) depletion leading to mitochondrial dysfunction. Several studies have shown the association of mitochondrial disorders with gastrointestinal dysfunction. In the present study, we investigated the activity of mitochondrial respiratory chain complexes activity in the stomach of rats with gastritis induced by indomethacin (IDM) and treated with omeprazole (OM), N-acetylcysteine (NAC) and the gastrin-releasing peptide receptor (GRPR) antagonist RC-3095. Adult male Wistar rats were pre-treated for 7 days with OM, NAC, RC-3095, combination of OM plus RC-3095, OM plus NAC and water (control). The animals were then submitted to fasting for 24 hr; IDM was administered. The rats were killed 6 hr later, and the stomachs were used for evaluation of macroscopic damage and respiratory chain activity. Our results showed that complex I and IV activities were not affected by administration of IDM. On the other hand, complex II and III activities were inhibited. In addition, OM plus RC-3095 and OM plus NAC did not reverse complex II activity inhibition. However, the complex III activity inhibition was reversed only with the combined use of OM plus RC-3095 and OM plus NAC. Our results are in agreement with previous studies indicating mitochondrial dysfunction in the pathophysiology of gastrointestinal tract disease and we suggest that GRPR antagonism might be a novel therapeutic strategy in gastritis.

    BH3-only protein, Bim, is a pro-apoptotic protein that mediates mitochondria-dependent cell death. However, the role of Bim in Helicobacter pylori-associated gastritis remains unclear. This study aimed to assess the cellular localization of Bim and its possible role in H. pylori-induced gastritis. The study was conducted on biopsy specimens obtained from 80 patients who underwent upper gastrointestinal endoscopy (H. pylori-negative: n=30, positive: n=50). Association between Bim mRNA expression and severity of gastritis was evaluated and the localization of Bim was examined by immunofluorescence. Bim mRNA expression was positively correlated with the degree of gastritis, as defined by the Sydney system. Immunohistochemical analysis confirmed increased Bim expression in H. pylori-infected gastric mucosa compared with uninfected mucosa in both humans and mice. Bim localized in myeloperoxidase- and CD138-positive cells of H. pylori-infected lamina propria and submucosa of the gastric tract, indicating that this protein is predominantly expressed in neutrophils and plasma cells. In contrast, Bim did not localize in CD20-, CD3-, or CD68-positive cells. Bim was expressed in the mitochondria, where it was partially co-localized with activated Bax and cleaved-PARP. In conclusion, Bim is expressed in neutrophils and plasma cells in H. pylori-associated gastritis, where it may participate in the termination of inflammatory response by causing mitochondria-mediated apoptosis in specific leucocytes.

    Peptic ulcer has frequently been associated with liver cirrhosis. The death rate for peptic ulcer in cirrhotics has been reported to be five times higher than in general population. The underlying mechanisms are poorly understood. Different factors have been claimed to be involved, such as alterations in serum gastrin level, gastric acid secretions, mucosal blood flow and decreased prostaglandin production in gastric mucosa. Moreover, Helicobacter pylori infection, when accurately assessed, is detectable in most peptic ulcer cirrhotics. Since the H. pylori infection strongly correlates with peptic ulcer in general population, it is necessary to clarify the role of H. pylori in the pathogenesis of peptic ulcer in cirrhosis before eradication can be proposed as a preventive measure.

    The recognition of Helicobacter pylori infection as a cause of peptic ulcer disease, medical regimens to eradicate the organism, and the widespread use of proton pump inhibition to suppress gastric acid secretion have revolutionized the management of peptic ulcer disease. As a result, successful medical management of peptic ulcer disease has largely supplanted the need for gastric surgery by general surgeons. Surgery is reserved for complications of the disease, refractory disease, or rare causes of ulcer disease such as gastrinoma and Zollinger-Ellison syndrome. In this report, we describe a case of intractable peptic ulcer disease that progressed to gastric outlet obstruction despite maximal medical therapy. We review the diagnostic studies utilized to evaluate the potential etiologies of peptic ulcer disease and the difficulty in diagnosing gastrinoma and Zollinger-Ellison in the setting of potent medical acid suppression therapy.

    Nodular gastritis is characterized histologically by hyperplasia and enlargement of lymphoid follicles in the lamina propria. With the objective of elucidating the relationship between different endoscopic types of nodular gastritis and lymphoid follicles, distributions of lymphoid follicles in the lamina propria were investigated in young gastric cancer patients with nodular gastritis. For the study, whole-mucosal step sectioning of each resected stomach was performed, the densities of lymphoid follicles of all specimens were measured microscopically, and the horizontal and depth distributions were calculated. For assessment in the horizontal direction, density distribution diagrams of lymphoid follicles were created. For assessment in the depth direction, the different endoscopic types of nodular gastritis were compared in the five different analysis sites. In the assessment of the horizontal distribution, no characteristic distribution tendencies were observed in either the granular type group or the scattered type group; however, it was found that areas with relatively high densities of lymphoid follicles generally coincided with the areas where nodular gastritis was observed endoscopically. These results suggested that hyperplasia and aggregation of lymphoid follicles in the lamina propria are involved at the sites where nodular gastritis is observed endoscopically. In the assessment of the depth distribution, lymphoid follicles tended to be more unevenly distributed in the upper lamina propria in the granular type group than in the scattered type at the three different analysis sites where nodular gastritis was observed endoscopically. These results suggested the possibility of a granular type characteristic.

    Outcome of Helicobacter pylori infection is different according to gastritis extension (i.e. antrum-restricted gastritis or pangastritis). The aim of this study is to evaluate whether different gastritis patterns are associated with specific gastrointestinal symptoms or clinical signs that could be suggestive of the topography of gastritis. 236 consecutive symptomatic outpatients were recruited in two tertiary centers. They filled in a validated and self-administered Rome III modular symptomatic questionnaire, and underwent gastroscopy with histological sampling. 154 patients with Helicobacter pylori infection were included. Clinical presentation did not differ between antrum-restricted gastritis and pangastritis, gastro-esophageal reflux disease being present in 48.2 and 54.1 % of patients and dyspepsia in 51.8 and 45.9 %, respectively. However, pangastritis statistically differed from antrum-restricted gastritis in that the presence of clinical signs (p < 0.0001) was observed in 33.7 % of the patients, consisting of iron deficiency (31.6 %), iron deficiency-anemia (20.4 %) and levothyroxine malabsorption (3.1 %). Symptoms are not helpful in suggesting gastritis pattern whereas their association with signs, accurately detected, is indicative for the presence of pangastritis.

    Data concerning prevalence rate of Helicobacter pylori gastritis in inflammatory bowel disease (IBD) patients is conflicting. We had studied the prevalence of Hp gastritis in newly diagnosed inflammatory bowel disease children before any pharmacological treatment was introduced. Ninety four consecutive children with inflammatory bowel diseased were enrolled into study, mean age 12.9 +/- 3.75 years, including 50 with Crohn's Disease (CD) and 44 with ulcerative colitis (UC). One hundred and four patients (mean age 13.6 +/- 4.2 year) referred for diagnostic evaluation because of recurrent abdominal pain, matched for age, sex and socioeconomic status served as a control. The results revealed a highly statistically lower prevalence of Hp gastritis in children with IBD as compared with controls (9.6% vs. 38.4%, p < 0.0001). Significantly more often Hp gastritis occurred in CD than UC patients. There was no statistical difference in mean age of IBD onset between Hp gastritis positive and negative groups (14.3 +/- 3.75 vs. 13.6 +/- 4.3 yr) was found. Our results show that in newly diagnosed IBD children, Hp gastritis is not unusual, but the prevalence rate is significantly lower comparing to the control group. The low Hp gastritis rate is not related to medical treatment, since the patients were studied before any was introduced.

    The present study aimed to investigate the association between endothelial progenitor cells (EPCs) and peptic ulcers in patients with or without type 2 diabetes mellitus (T2DM), in association with the efficiency of peptic ulcer treatment. The study recruited healthy subjects and peptic ulcer patients with or without T2DM. All the ulcer patients, including those with and without T2DM, were administered omeprazole for 8 weeks. Peptic ulcer patients with T2DM were additionally treated with glipizide and novolin. Blood samples were then obtained from the three groups following ulcer treatment. CD133+ cells were isolated from the blood samples using magnetic bead selection, and cultured in complete medium 199. Morphological and quantity changes in EPCs were observed by light and fluorescence microscopy. In addition, flow cytometric analysis was used to quantify the number of vascular endothelial cells. The treatment was partially effective in 7 of the 32 peptic ulcer patients without T2DM and 12 of the 32 peptic ulcer patients with T2DM. However, this treatment was ineffective in 20 of the 32 peptic ulcer patients with T2DM. Notably, 25 peptic ulcer patients without T2DM were defined as completely recovered following treatment. In addition, the number of circulating EPCs as well as their colony forming ability was significantly reduced (P<0.05) in the peptic ulcer patients with T2DM following ulcer treatment, compared with the other groups. Circulating EPC counts were significantly increased in peptic ulcer patients without T2DM, as compared with the healthy controls. With regards to colony formation, peptic ulcer patients without T2DM did not exhibit improved colony formation ability.

    This review of the current literature aims to study correlations between the chemical structure and gastric anti-ulcer activity of tannins. Tannins are used in medicine primarily because of their astringent properties. These properties are due to the fact that tannins react with the tissue proteins with which they come into contact. In gastric ulcers, this tannin-protein complex layer protects the stomach by promoting greater resistance to chemical and mechanical injury or irritation. Moreover, in several experimental models of gastric ulcer, tannins have been shown to present antioxidant activity, promote tissue repair, exhibit anti Helicobacter pylori effects, and they are involved in gastrointestinal tract anti-inflammatory processes. The presence of tannins explains the anti-ulcer effects of many natural products. PMID:22489149

    Intractable bleeding caused by radiation-induced gastritis is rare. We describe a 69-year-old man with intractable hemorrhagic gastritis induced by postoperative radiotherapy for the treatment of esophageal carcinoma. Although anti-secretory therapy with or without octreotide was initiated for hemostasis over three months, melena still occurred off and on, and the patient required blood transfusions to maintain stable hemoglobin. Finally growth hormone was used in the treatment of hemorrhage for two weeks, and hemostasis was successfully achieved. This is the first report that growth hormone has been used to control intractable bleeding caused by radiation-induced gastritis.

    AIMS: To investigate the prevalence of Helicobacter pylori associated chronic gastritis in patients with gastric cancer. METHODS: Serum IgG antibodies for H pylori were determined in 54 consecutive patients with gastric carcinoma. The prevalence of H pylori in gastric mucosa was also examined histologically (modified Giemsa) in 32 patients from whom adequate biopsy specimens of the antrum and corpus were available. Thirty five patients with gastrointestinal tumours outside the stomach and 48 with non-gastrointestinal malignancies served as controls. RESULTS: Of the 54 patients, 38 (70%) had H pylori antibodies (IgG) in their serum (three additional patients had H pylori antibodies IgA, class specific but not IgG specific). This prevalence was significantly higher (p less than 0.05) than that (49%) in the 35 controls. No differences in prevalence of H pylori antibodies were found between gastric cancer cases of intestinal (IGCA) or diffuse (DGCA) type, both these types showing H pylori antibodies (IgG) in 71% of the patients. In the subgroup of 32 subjects, five patients had normal gastric mucosa and four showed corpus limited atrophy ("pernicious anaemia type" atrophy of type A). All of these nine patients had no evidence of current or previous H pylori infection in serum (no IgG antibodies) or in tissue sections (negative Giemsa staining). The remaining 23 patients had antral or pangastritis, and all had evidence of current or previous H pylori infection. CONCLUSIONS: H pylori associated chronic gastritis was the associated disease in 75% of the patients with gastric cancer occurring equally often in both IGCA and DGCA groups. About 25% of cases seem to have a normal stomach or severe corpus limited atrophy, neither of which showed evidence of concomitant H pylori infection. PMID:1577969

    Helicobacter pylori (H. pylori) infection is among the most prevalent human infections. CXCL12 is a well-known CXC chemokine involved in inflammation and play major roles in angiogenesis. There is currently very limited data on the role of CXCL12 in peptic ulcer disease. Hence, we aimed to explore whether CXCL12 is involved in the pathogenesis of peptic ulcer induced by H. pylori. In this study, we enrolled 102 H. pylori-infected patients, including 51 with active ulcer (GA) and 51 with healing ulcer (GH). We also recruited 50 healthy subjects as control, which did not show any sign or symptoms of chronic inflammatory diseases, infection, or immune-related disorders. Endoscopy was performed to determine the stage of the disease. ELISA was used for detection of H. pylori infection and CXCL12 measurement. We also employed western blotting to detect CXCL12 in ulcerative lesions of H. pylori. Demographic data were also collected by questionnaire. Our results demonstrated that CXCL12 serum levels in GA group (151.8±18.31pg/mL) were significantly higher than those in GH (36.89±6.78pg/mL) and control groups (33.77±9.12pg/mL) (P<0.0001). However, we did not observe a significant difference between GH and control groups. Moreover, overexpression of CXCL12 in gastric lesions of patients in GA group was confirmed by Western blot analysis. According to the result of the present study, it could be concluded that CXCL12 is involved in the pathogenesis and healing of H. pylori-induced peptic ulcer. CXCL12 serum levels may also be used to distinguish between GA and GH phases of the disease.

    The aim of this paper was to determine the topographic distribution of gastritis lesions in pigs through an open source geographic information system (GIS) software analysis. The stomachs of 146 Italian heavy pigs were collected at slaughter and subjected to macroscopic pathological examination of the internal mucosa. A total of 623 lesions were either classified as hyperplastic or follicular (97%) with the remaining minority of lesions categorised as atrophic and simple. The hyperplastic gastritis lesions had an average surface of 77.8 cm2 and were mainly located in an oval shaped area of the fundus region of the stomach near the Curvatura ventriculi major. The follicular gastritis lesions had generally a smaller surface (40.3 cm2) and were concentrated in two distinct small areas of the pyloric region. The GIS analysis provided the opportunity to produce useful maps showing the distribution and characteristics of gastritis in pigs.

    An on-chip lectin microarray based glycomic approach is employed to identify glyco markers for different gastritis and gastric cancer. Changes in protein glycosylation have impact on biological function and carcinogenesis. These altered glycosylation patterns in serum proteins and membrane proteins of tumor cells can be unique markers of cancer progression and hence have been exploited to diagnose various stages of cancer through lectin microarray technology. In the present work, we aimed to study the alteration of glycan structure itself in different stages of gastritis and gastric cancer thoroughly. In order to perform the study from both serum and tissue glycoproteins in an efficient and high-throughput manner, we indigenously developed and employed lectin microarray integrated on a microfluidic lab-on-a-chip platform. We analyzed serum and gastric biopsy samples from 8 normal, 15 chronic Type-B gastritis, 10 chronic Type-C gastritis, and 6 gastric adenocarcinoma patients and found that the glycoprofile obtained from tissue samples was more distinctive than that of the sera samples. We were able to establish signature glycoprofile for the three disease groups, that were absent in healthy normal individuals. In addition, our findings elucidated certain novel signature glycan expression in chronic gastritis and gastric cancer. In silico analysis showed that glycoprofile of chronic gastritis and gastric adenocarcinoma formed close clusters, confirming the previously hypothesized linkage between them. This signature can be explored further as gastric cancer marker to develop novel analytical tools and obtain in-depth understanding of the disease prognosis. PMID:24959308

    1999-09-01

    Currently there is controversial evidence that suggests that the accepted incidence of atrophic gastritis of 1.2 to 3.3% in patients with Helicobacter pylori gastritis may be increased by the long-term suppression of acid by a proton pump inhibitor (omeprazole). The purpose of this study is to show whether lesser forms of acid suppression by antacids or H2 receptor antagonists may have an influence on the development of atrophic gastritis. The authors recently reported a study in which a cohort of 36 patients with symptoms of dyspepsia were followed clinically for a period of 7 to 19 years. In that report all subjects underwent upper endoscopy with two biopsy specimens each from the antrum and fundus, on at least two occasions, 7 to 19 years apart. A diagnosis of atrophic gastritis was based on the interpretation of these biopsies by two gastrointestinal pathologists. The presence of H. pylori colonization was determined by tissue sampling and by a campylobacter-like organisms test of the antrum. Of the 36 patients in the authors' previous report, 33 had adequate baseline and follow-up data on medications consumed throughout the period of the study. In their current report they now present the findings of a retrospective review in which they correlate the presence of atrophic gastritis with the sole use of antacids and H2 receptor antagonists throughout the period of the study. In the cohort of 33 patients evaluated from the previous report, the authors found that atrophic gastritis had developed in all 28 patients positive for H. pylori, and in none of the 5 patients negative for H. pylori (p < 0.0001). A retrospective analysis of this previously studied cohort of 33 patients revealed that the use of antacids and H2 receptor antagonists did not predict the development of atrophic gastritis in either H. pylori-negative or -positive subjects. In a retrospective analysis of a cohort of 33 patients followed for an average of 11.7 years, atrophic gastritis developed in

Indomethacin-induced ulcer in a rat model was used for this testing. Mentha microphylla, Brassica oleracea Capitata (Cabbage), B. oleracea Botrytis (cauliflower) aqueous fraction, Portolaca oleracea polysaccharide fraction, Oreganum marjoranum, Matricaria recutita, Solanum nigrum hydrophilic and lipophilic fractions, in addition to the chloroform fraction of Portolaca oleracea and Cicorium intybus afforded high protection against the incidence of gastric ulcer (~95%). O. syriacum hydrophilic and lipophilic fractions and gum arabic afforded moderate prophylactic effect. L. sicerarea, C. intybus hydrophilic fractions and M. microphylla lipophilic fraction were inactive. Herbs represent excellent resources for cost-effective and readily available gastro-protective remedies without side effects. PMID:25276211

    A retrospective analysis was done of 106 patients who received radiation therapy for brain metastasis. Dexamethasone therapy was instituted in 97 patients. Peptic ulcer disease developed in 5 of 89 patients (5.6 percent) who received a dosage of at least 12 mg a day, but did not occur in patients who received a lower dose or in those who did not receive steroids. The interval between institution of dexamethasone therapy and the development of peptic ulcer disease ranged from three to nine weeks. Two patients had perforated ulcers, one of whom required surgical resection. Peptic ulcer disease contributed to the general deterioration and death of three of the five patients. Overall, in 14 of the 89 patients (15.7 percent) a complication of steroid therapy developed in the form of peptic ulcer disease, steroid myopathy or diabetes mellitus (or a combination of these).

    Introduction A perforated peptic ulcer (PPU) is a rare but major complication of gastroduodenal peptic ulcer disease. Literature is scarce on this subject in the pediatric population and most articles describe a surgical treatment by laparotomy. We aim to review all our cases of pediatric PPU treated over the past 16 years and compare these to literature to deduce potential benefits and disadvantages regarding laparoscopic treatment of PPU in children. Materials and Methods A retrospective study of all cases of PPU treated at the Lenval Hospital in Nice (France) and the Queen Fabiola University Hospital for Children in Brussels (Belgium) between 1998 and 2015 was performed. Results A total of five children were treated for PPU (2 females). The average age was 11 years (range, 3-17). All of them were surgically treated with laparoscopic simple suture of the perforation and placement of an omental patch. There were no mortalities, no conversions, and no extra-abdominal complications or wound dehiscences. Mean operating time was 78.6 minutes (range, 70-115 minutes). Mean duration of intravenous treatment was 6 days (range, 4-12 days). One reintervention was performed for abdominal infection. In one patient, an abdominal drain was left in place for 2 days. The mean time before refeeding was 3.4 days (range, 3-4 days) and mean length of stay was 12 days (range, 7-30 days). Conclusion Laparoscopic repair is safe and feasible for PPU and should be the gold standard for treatment of PPU in children.

    Titanium dioxide (TiO2) nanoparticles are widely used as a food additive and coloring agent in many consumer products however limited data is available on the nano-TiO2 induced genotoxicity persistence. Thus, this study investigated the persistence of nano-TiO2 induced genotoxicity and possible induction of chronic gastritis in mice. The mice were orally administered 5, 50 or 500 mg/kg body weight nano-TiO2 for five consecutive days, and then mice from each dosage group were sacrificed 24 h or one or two weeks after the last treatment. The administration of nano-TiO2 resulted in persistent apoptotic DNA fragmentation and mutations in p53 exons (5-8) as well as significant persistent elevations in malondialdehyde and nitric oxide levels and decreases in the reduced glutathione level and catalase activity compared with the control mice in a dose- and time-dependent manner. Necrosis and inflammation were evident upon histological examination. These findings could be attributed to the persistent accumulation of nano-TiO2 at the tested doses at all three time points. Based on these findings, we conclude that the administration of nano-TiO2, even at low doses, leads to persistent accumulation of nano-TiO2 in mice, resulting in persistent inflammation, apoptosis and oxidative stress, ultimately leading to the induction of chronic gastritis.

    Peptic ulcer disease is a common illness, affecting a considerable number of people worldwide, and its occurrence can be influenced by environmental and genetic factors. Heat shock proteins (HSPs) function mostly as molecular chaperones, and are induced by various stresses. The A to G transition at position 1267 of the HSPA1B gene was shown to correlate with changes in the level of HSPA mRNA expression. Here, the relation between A1267G polymorphism of the HSPAIB gene and risk of peptic ulcer in the Iranian population was evaluated. One hundred subjects, who underwent gastroscopy, took part in the study. DNA samples extracted from the biopsy tissues were genotyped using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). After gastroscopy, peptic ulcer was diagnosed for 50 patients; among them the distribution of AA/AB/BB genotypes was 10, 88 and 2%, respectively. As for the other 50 subjects (without peptic ulcer) included in the control group, the AA/AB/BB genotypes were identified as 40, 52 and 8%, respectively. A significant association was found between the HSPA1B genotype and peptic ulcer (6.76 OR; 95% CI, 2.26-20.2; p = 0.0006). Thus, the HSPA1B A1267G polymorphism may be a marker of susceptibility to peptic ulcer.

    The Armanni-Ebstein phenomenon, which is found in the kidneys in diabetic ketoacidosis, has also been proposed as an independent diagnostic postmortem marker for hypothermia. A case is reported to demonstrate the possibility of a more complex inter-related etiology in certain instances. A 44-year-old man with a past history of hospital admission for hypothermia, alcoholism and insulin dependent diabetes mellitus was found dead at his home address. At autopsy there were prominent superficial erosive gastritis (Wischnewsky spots) in keeping with terminal hypothermia. In addition there was also marked cortical pallor of the kidneys due to subnuclear renal tubular epithelial vacuolization (Armanni-Ebstein phenomenon). Thus there was evidence for both hypothermia and Armanni-Ebstein phenomenon, suggesting a relationship. Subsequent biochemical testing of vitreous humor, however, demonstrated markedly elevated levels of glucose (36.5 mmol/l; N = 3.6-6.0 mmol/l), β-hydroxybutyrate (23.2 mmol/l; N < 0.3 mmol/l), and lactate (29.4 mmol/l; N = 0.2-2.0 mmol/l). Death was, therefore, due to diabetic ketoacidosis complicated by hypothermia. Diabetes mellitus has a known association with both hypothermia and Armanni-Ebstein phenomenon, thus, before renal tubular vacuolization can be taken as a marker of hypothermia in isolation, it is important to consider the possibility that in certain cases underlying diabetic ketoacidosis may be present.

    Abstract A meta-analysis was performed to assess the diagnostic value of gastrin-17 (G-17) for the early detection of chronic atrophic gastritis (CAG). An extensive literature search was performed, with the aim of selecting publications that reported the accuracy of G-17 in predicting CAG, in the following databases: PubMed, Science Direct, Web of Science, Chinese Biological Medicine, Chinese National Knowledge Infrastructure, Wanfang, and VIP. To assess the diagnostic value of G-17, the following statistics were estimated and described: sensitivity, specificity, diagnostic odds ratios (DOR), summary receiver operating characteristic curves, area under the curve (AUC), and 95% confidence intervals (CIs). Thirteen studies that met the inclusion criteria were included in this meta-analysis, comprising 894 patients and 1950 controls. The pooled sensitivity and specificity of these studies were 0.48 (95% CI: 0.45–0.51) and 0.79 (95% CI: 0.77–0.81), respectively. The DOR was 5.93 (95% CI: 2.93–11.99), and the AUC was 0.82. G-17 may have potential diagnostic value because it has good specificity and a moderate DOR and AUC for CAG. However, more studies are needed to improve the sensitivity of this diagnostic tool in the future. PMID:27149493

    Background The term nodular is not included in the Sydney classification and there is no widely accepted histopathological definition. It has been proposed that the presence of antral nodularity could predict Helicobacter pylori (H. pylori) infection. The aim of this study was to determine the diagnostic accuracy of nodular gastritis (NG) for H. pylori infection after a rigorous standardization process, and to describe the associated histopathological characteristics. Materials and methods Endoscopic images of patients submitted to endoscopy with biopsy sampling were included. Endoscopic images were distributed among six endoscopists. The analysis was performed sequentially in three rounds: the first round assessed the interobserver variability, the second evaluated the intraobserver variability, and the third calculated the interobserver variability after training. A correlation analysis between endoscopic and histopathological findings was performed. Results A total of 917 studies were included. In the first analysis of interobserver variability, a poor kappa value (0.078) was obtained. The second evaluation yielded good intraobserver variability, with kappa values of 0.62–0.86. The evaluation of interobserver variability after training revealed an improvement in the kappa value of 0.42. A correlation was found between endoscopic images and histopathological reports. Conclusion There was a strong correlation between NG and H. pylori, but only after rigorous evaluation. The use of the term NG requires extensive standardization before it can be used clinically.

    The gastric H+/K(+)-ATPase has been implicated as a major autoantigen in pernicious anaemia in humans and in thymectomy-induced autoimmune gastritis in mice. Here we have shown that autoimmune gastritis can be generated by direct immunization of non-thymectomized BALB/c mice with mouse gastric H+/K(+)-ATPase in complete Freund's adjuvant. The gastritis was characterized by infiltration of the gastric submucosa and mucosa with macrophages, CD4+ and CD8+ T cells, and B cells and by circulating autoantibodies to the H+/K(+)-ATPase. The mononuclear infiltrate within the gastric mucosa was accompanied by loss of parietal and zymogenic cells and accumulation of small immature epithelial cells. Splenocytes from gastritic mice adoptively transferred gastritis to naive recipients. Cessation of immunization resulted in decrease in autoantibody titre and regeneration of parietal and zymogenic cells. The results directly confirm that the gastric H+/K(+)-ATPase is the causative autoantigen in the genesis of autoimmune gastritis. Recovery of the lesion following cessation of immunization suggests that homeostatic mechanisms can reverse a destructive autoimmune process.

    Background. Traditional Chinese medicine (TCM) has long been used to treat chronic atrophic gastritis (CAG). The aim of the present study was to evaluate the TCM syndrome characteristics of CAG and its core pathogenesis so as to promote optimization of treatment strategies. Methods. This study was based on a participant survey conducted in 4 hospitals in China. Patients diagnosed with CAG were recruited by simple random sampling. Exploratory factor analysis (EFA) was conducted on syndrome extraction. Results. Common factors extracted were assigned to six syndrome patterns: qi deficiency, qi stagnation, blood stasis, phlegm turbidity, heat, and yang deficiency. Distribution frequency of all syndrome patterns showed that qi deficiency, qi stagnation, blood stasis, phlegm turbidity, and heat excess were higher (76.7%–84.2%) compared with yang deficiency (42.5%). Distribution of main syndrome patterns showed that frequencies of qi deficiency, qi stagnation, phlegm turbidity, heat, and yang deficiency were higher (15.8%–20.8%) compared with blood stasis (8.3%). Conclusions. The core pathogenesis of CAG is combination of qi deficiency, qi stagnation, blood stasis, phlegm turbidity, heat, and yang deficiency. Therefore, treatment strategy of herbal prescriptions for CAG should include herbs that regulate qi, activate blood, resolve turbidity, clear heat, remove toxin, and warm yang. PMID:28077948

    Naïve antigen-specific CD4(+) T cells (TxA23) induce autoimmune gastritis when transferred into BALB/c nu/nu mice. Transfer of in vitro pre-differentiated Th1 or Th17 TxA23 effector T cells into BALB/c nu/nu recipients induces distinct histological patterns of disease. We have previously shown that co-transfer of polyclonal naturally occurring Treg (nTreg) suppressed development of Th1-, but not Th17-mediated disease. Therefore, we analysed the suppressive capacity of different types of Treg to suppress Th1- and Th17-mediated autoimmune gastritis. We compared nTreg with polyclonal TGFbeta-induced WT Treg (iTreg) or TGFbeta-induced antigen-specific TxA23 iTreg in co-transfer experiments with Th1 or Th17 TxA23 effector T cells. 6 weeks after transfer in vitro pre-differentiated TxA23 Th1 and Th17 effector cells induced destructive gastritis. Th1-mediated disease was prevented by co-transfer of nTreg and also antigen-specific iTreg, whereas WT iTreg did not show an effect. However, Th17-mediated disease was only suppressed by antigen-specific iTreg. Pre-activation of nTreg in vitro prior to transfer did not increase their suppressive activity in Th17-mediated gastritis. Thus, antigen-specific iTreg are potent suppressors of autoimmune gastritis induced by both, fully differentiated Th1 and Th17 effector cells.

    Atrophic autoimmune gastritis (AAG) is a condition of chronic inflammation and atrophy of stomach mucosa, for which development can be partially triggered by the bacterial pathogen Helicobacter pylori (HP). HP can cause a variety of gastric diseases, such as duodenal ulcer (DU) or gastric cancer (GC). In this study, a comparative proteomic approach was used by two-dimensional fluorescence difference gel electrophoresis (DIGE) to identify differentially expressed proteins of HP strains isolated from patients with AAG, to identify markers of HP strain associated with AAG. Proteome profiles of HP isolated from GC or DU were used as a reference to compare proteomic levels. Proteomics analyses revealed 27 differentially expressed spots in AAG-associated HP in comparison with GC, whereas only 9 differential spots were found in AAG-associated HP profiles compared with DU. Proteins were identified after matrix-assisted laser desorption ionization (MALDI)-TOF and peptide mass fingerprinting. Some AAG-HP differential proteins were common between DU- and GC-HP (peroxiredoxin, heat shock protein 70 [HSP70], adenosine 5'-triphosphate [ATP] synthase subunit α, flagellin A). Our results presented here may suggest that comparative proteomes of HP isolated from AAG and DU share more common protein expression than GC and provide subsets of putative AAG-specific upregulated or downregulated proteins that could be proposed as putative markers of AAG-associated HP. Other comparative studies by two-dimensional maps integrated with functional genomics of candidate proteins will undoubtedly contribute to better decipher the biology of AAG-associated HP strains.

    Abstract Persistent exacerbation of a peptic ulcer may lead to a complicated peptic ulcer (perforation or/and bleeding). The management of complicated peptic ulcers has shifted from acid-reducing vagotomy, drainage, and gastrectomy to simple local suture or non-operative (endoscopic/angiographic) hemostasis. We were interested in the long-term effects of this trend change. In this study, complicated peptic ulcer patients who received acid-reducing vagotomy were compared with those who received simple suture/hemostasis to determine the risk of ischemic heart disease (IHD). This retrospective cohort study analyzed 335,680 peptic ulcer patients recorded from 2000 to 2006 versus 335,680 age-, sex-, comorbidity-, and index-year matched comparisons. Patients with Helicobacter pylori (HP) infection were excluded. In order to identify the effect of vagus nerve severance, patients who received gastrectomy or antrectomy were also excluded. The incidence of IHD in both cohorts, and in the complicated peptic ulcer patients who received acid-reducing vagotomy versus those who received simple suture or hemostasis was evaluated. The overall incidence of IHD was higher in patients with peptic ulcer than those without peptic ulcer (17.00 vs 12.06 per 1000 person-years), with an adjusted hazard ratio (aHR) of 1.46 based on multivariable Cox proportional hazards regression analysis controlling for age, sex, Charlson's comorbidity index, and death (competing risk). While comparing peptic ulcer patients with acid-reducing vagotomy to those with simple suture/hemostasis or those without surgical treatment, the aHR (0.58) was the lowest in the acid-reducing vagotomy group. Patients with peptic ulcer have an elevated risk of IHD. However, complicated peptic ulcer patients who received acid-reducing vagotomy were associated with reduced risk of developing IHD.

    Since National Health Insurance covered eradication therapy for H. pylori infected gastritis, all patients with H. pylori infection could be received eradication under insurance. Cure of H. pylori infection improves histological gastritis, also atrophic change, and intestinal metaplasia. Prevention of H. pylori associated diseases such as gastric cancer is expected. According to Insurance instruction, it is carried out in order of endoscopic diagnosis of chronic gastritis, diagnosis of H. pylori infection, and eradication treatment. Endoscopic examination prior to H. pylori diagnosis is necessary for screening of gastric cancer. Endoscopic finding of RAC (regular arrangement of collecting venules) in the angle of stomach suggests lack of infection with H. pylori, disappearance of RAC suspects H. pylori infection.

    Fourteen patients were selected with advanced superficial chronic gastritis (grade II), marked chronic gastritis with partial atrophy (grade III), or chronic gastritis with total atrophy in which intestinal metaplasia was observed (grade IV). Azathioprine was administrated to all of them for periods varying from two and a half to six months. There were no side effects except in one patient, in whom nausea and vomiting made it necessary to remove him from the trial. Acid output in these 14 patients showed an average change which was statistically significant. Statistical analysis of the sample as a whole shows that, with a 0·95 probability improvement could be expected in 37 to 85% of the patients given azathioprine. ImagesFig. 1Fig. 2 PMID:4696531

    Abstract The risk of peptic ulcer disease (PUD) among patients with depression has raised concern. This study determined the association between depression and the subsequent development of PUD using claims data. Patients newly diagnosed with depression in 2000 to 2010 were identified as depression cohort from the Taiwan National Health Insurance Research Database. The comparison cohort was randomly selected from subjects without depression, frequency matched by age and gender and diagnosis date, with a size 2-fold of the size of the depression cohort. The incidence of PUD was evaluated for both cohorts by the end of 2011. We calculated the hazard ratios (HRs) and 95% confidence intervals (CIs) of PUD using the Cox proportional hazards regression model. The depression cohort consisted of 23,536 subjects (129,751 person-years), and the comparison cohort consisted of 47,069 subjects (285,592 person-years). The incidence of PUD was 2-fold higher in the depression cohort than in the comparison cohort (33.2 vs 16.8 per 1000 person-years) with an age adjusted HR of 1.97 (95% CI = 1.89–2.06) or a multivariable adjusted HR of 1.35 (95% CI = 1.29–1.42). Depression might increase the risk of developing PUD. Prospective clinical studies of the relationship between depression and PUD are warranted. PMID:26705225

    Upper gastrointestinal bleeding from peptic ulcer disease is a common clinical event, resulting in considerable patient morbidity and significant health care costs. Inhibiting gastric acid secretion is a key component in improving clinical outcomes, including reducing rebleeding, transfusion requirements, and surgery. Raising intragastric pH promotes clot stability and reduces the influences of gastric acid and pepsin. Patients with high-risk stigmata for ulcer bleeding (arterial bleeding, nonbleeding visible vessels, and adherent clots) benefit significantly from and should receive high-dose intravenous proton pump inhibitors (PPIs) after successful endoscopic hemostasis. For patients with low-risk stigmata (flat spots or clean ulcer base), oral PPI therapy alone is sufficient. For oozing bleeding (an intermediate risk finding), successful endoscopic hemostasis and oral PPI are recommended. Using intravenous PPIs before endoscopy appears to reduce the frequency of finding high-risk stigmata on later endoscopy, but has not been shown to improve clinical outcomes. High-dose oral PPIs may be as effective as intravenous infusion in achieving positive clinical outcomes, but this has not been documented by randomized studies and its cost-effectiveness is unclear.

    The authors have previously studied pepsinogen (Pg) secretion from isolated intact esophageal mucosa of the bullfrog R. catesbeiana. By stimulus-response studies using agonists and antagonists they characterized specific stimulation of cholinergic, adrenergic and peptidergic receptors and interaction of cAMP and Ca/sup 2 +/ dependent pathways. To understand cell mechanisms more definitively and to relate these to morphology it was necessary to isolate peptic cells. Esophageal mucosa was digested with 0.1% collagenase for 80-100 min and sieved through teflon mesh. One esophagus yielded approximately 10/sup 7/ cells, 70% pure and 89 +/- 5% viable. Basal secretion was 3% of Pg content/hr. The cells responded to graded concentrations of bombesin, bethanechol, IBMX, 8Br-cAMP, forskolin, TPA (12-0-tetradecanoyl phorbol 13 acetate) and A23187. The response to (TPA + A23187) was double the additive single output values; (TPA + A23187 + forskolin) stimulated secretion of more than double the sum of the 3 component stimuli. In calcium and magnesium-free medium, the A23187 response and the synergistic response of combinations were both lost. They have identified 3 messengers for Pg cell stimulation - cAMP, Ca/sup 2 +/ mobilization and protein kinase C - each of which can be separately stimulated, and when combined are strongly synergistic.

    Background. Helicobacter pylori (HP) infection and nonsteroidal anti-inflammatory drugs (NSAID) use are considered the main risk to develop peptic ulcer disease (PUD). However, PUD also occurs in the absence of HP infection and/or NSAID use. Recently, we have found evidence that Epstein-Barr virus (EBV) reactivation increases the risk to develop premalignant and malignant gastric lesions. Objective. To study a possible association between EBV and PUD. Methods. Antibodies against an EBV reactivation antigen, HP, and the HP virulence factor CagA were measured in sera from 207 Mexican subjects, controls (healthy individuals, n = 129), and PUD patients (n = 78, 58 duodenal and 20 gastric ulcers). Statistical associations were estimated. Results. Duodenal PUD was significantly associated with high anti-EBV IgG titers (p = 0.022, OR = 2.5), while anti-EBV IgA was positively associated with gastric PUD (p = 0.002, OR = 10.1). Conclusions. Our study suggests that EBV reactivation in gastric and duodenal epithelium increases the risk to develop PUD. PMID:26199856

    Helicobacter pylori causes chronic (type B) gastritis. The 'intestinal' form of gastric cancer arises against a background of chronic gastritis, and prospective epidemiological studies have shown that H pylori is a major risk factor for this. An increase in mucosal cell proliferation increases the likelihood of a neoplastic clone of epithelial cells emerging where there is chronic epithelial cell injury associated with H pylori gastritis. In vitro bromodeoxyuridine labelling of endoscopic antral biopsy specimens was used to measure mucosal cell proliferation in H pylori associated gastritis before and after therapy for H pylori triple infection. Cell proliferation was increased in H pylori associated gastritis patients compared with normal controls and patients with H pylori negative chronic gastritis (p = 0.0001; Tukey's Studentised range). There was no difference in antral epithelial cell proliferation between duodenal ulcer and non-ulcer subjects infected with H pylori (p = 0.62; Student's t test). Antral mucosal cell proliferation fell four weeks after completing triple therapy, irrespective of whether or not H pylori had been eradicated (p = 0.0001). At retesting six to 18 months later (mean = 12 months), however, those in whom H pylori had not been successfully eradicated showed increased mucosal proliferation compared with both H pylori negative subjects at a similar follow up interval and all cases (whether H pylori positive or negative) four weeks after completion of triple therapy (p = 0.024). These findings suggest that H pylori infection causes increased gastric cell proliferation and in this way may play a part in gastric carcinogenesis. PMID:7698690

    We estimated the prevalences of Helicobacter pylori (formerly called Campylobacter pylori) infection and histologic gastritis in 113 asymptomatic persons, using endoscopic biopsy of the gastric antrum and corpus. Unsuspected lesions, mainly mucosal erosions, were revealed at endoscopy in 16 subjects (14 percent). Gastritis was found in 42 subjects (37 percent), of whom 36 (32 percent of the total) were found to be infected with H. pylori on the basis of hematoxylin-eosin staining. H. pylori was not found in any of the 71 subjects with normal histologic features. Gastritis and H. pylori were noted in both the antrum and corpus in 75 percent of those infected (n = 27). The prevalence of H. pylori infection increased from 10 percent (2 of 20 subjects) in those between the ages of 18 and 29, to 47 percent (7 of 15) in those between the ages of 60 and 69, but the effect of age did not reach statistical significance. The prevalence of gastritis increased significantly with advancing age. Stepwise logistic regression analysis revealed that the relative risk for H. pylori infection associated with recent (within six months) antibiotic use was 5.8 (95 percent confidence interval, 1.5 to 22.1), whereas the relative risk was 6.5 (95 percent confidence interval, 1.4 to 29.2) for those who had never used bismuth compounds. We conclude that histologic gastritis and H. pylori infection commonly occur in the stomach of apparently normal persons and increase in prevalence with advancing age. All the subjects with H. pylori infection had gastritis, suggesting a possible etiologic role for the bacterium in the histologic lesion.

    AIM: To investigate the therapeutic effects of DA-9601 on sodium taurocholate (TCA)-induced chronic reflux gastritis in SD rats. METHODS: In this study, we have investigated the therapeutic effects of DA-9601 on chronic erosive and atrophic gastritis induced by 6 mo of TCA administration (5 mmol/L in drinking water) in SD rats. RESULTS: Four weeks of DA-9601 administration (0.065%, 0.216% in rat chow), following the withdrawal of TCA treatment, resulted in a significant decrease in total length of erosions in rats in a dose-dependent manner. Furthermore, the indicators of atrophic gastritis, such as reduced mucosal thickness and reduction in the number of parietal cells, were improved by the administration of DA-9601 in a dose-related manner. DA-9601 also attenuated inflammatory cell infiltration and the proliferation of collagenous fiber in the gastric mucosa. The improvement in the reduction of the gastric mucus was observed in the rats receiving a high dose of DA-9601 (0.216%). The therapeutic effect of DA-9601 on experimental chronic erosive gastritis was superior to that of rebamipide (1.08% in rat chow). Biochemical analyses showed increased mucosal prostaglandin E2 and reduced glutathione levels by DA-9601 treatment. CONCLUSION: We suggest that DA-9601 is a promising agent for the treatment of chronic erosive and atrophic gastritis with an etiological factor of bile reflux. Increased mucosal prostaglandin E2 and reduced glutathione by DA-9601 treatment may be therapeutic mechanisms for chronic erosive and atrophic gastritis. PMID:16437712

    Chronic gastritis causes significant morbidity and mortality in captive cheetahs but is rare in wild cheetahs despite colonization by abundant spiral bacteria. This research aimed to identify the Helicobacter species that were associated with gastritis in captive cheetahs but are apparently commensal in wild cheetahs. Helicobacter species were characterized by PCR amplification and sequencing of the 16S rRNA, urease, and cagA genes and by transmission electron microscopy of frozen or formalin-fixed paraffin-embedded gastric samples from 33 cheetahs infected with Helicobacter organisms (10 wild without gastritis and 23 captive with gastritis). Samples were screened for mixed infections by denaturant gel gradient electrophoresis of the 16S rRNA gene and by transmission electron microscopy. There was no association between Helicobacter infection and the presence or severity of gastritis. Eight cheetahs had 16S rRNA sequences that were most similar (98 to 99%) to H. pylori. Twenty-five cheetahs had sequences that were most similar (97 to 99%) to “H. heilmannii” or H. felis. No cheetahs had mixed infections. The ultrastructural morphology of all bacteria was most consistent with “H. heilmannii,” even when 16S rRNA sequences were H. pylori-like. The urease gene from H. pylori-like bacteria could not be amplified with primers for either “H. heilmannii” or H. pylori urease, suggesting that this bacteria is neither H. pylori nor “H. heilmannii.” The cagA gene was not identified in any case. These findings question a direct role for Helicobacter infection in the pathogenesis of gastritis and support the premise that host factors account for the differences in disease between captive and wild cheetah populations.

    The incidence of Helicobacter pylori and non-steroidal anti-inflammatory drug (NSAID)-negative peptic ulcer disease has increased over the last two decades, especially in the Western world and in countries with low H. pylori infection rates. Idiopathic peptic ulcer disease is a recently described entity which relates to peptic ulcers not caused by H. pylori, NSAID/aspirin therapy, other ulcerogenic organisms and drugs, or other rare malignant and benign diseases. Structural and secreted mucins create the unstirred gastric mucus layer and maintain a stable pH above the gastric mucosa. This mucous layer prevents enzymatic attack by acid and pepsin. Inhibition of cyclooxygenase by NSAID and aspirin inhibits prostaglandin production, inhibits mucin and bicarbonate secretion, and exposes the mucosa to the toxic effects of acid and intragastric enzymes. There is also a complex relationship between H. pylori and different mucin subtypes which on one hand facilitates mucin invasion but on the other hand protects the gastric mucosa. Genetic and epigenetic changes in the mucin molecule may be responsible for idiopathic peptic ulcer disease, but this hypothesis must be further investigated. Herein, the mucin hypothesis of idiopathic peptic ulcer disease is explored.

    Background: Peptic ulcers are among the most common causes of upper gastrointestinal (GI) bleeding in children. The standard care for GI bleeding is endoscopy for diagnostic and therapeutic purposes. We aimed to assess the effect of topical tranexamic acid (TXA) via endoscopic procedures in children with GI bleeding caused by bleeding ulcers. Procedure: In this randomised controlled trial, 120 children were evaluated by diagnostic procedures for GI bleeding, of which 63 (30 girls, 33 boys) aged 1-month to 15 years were recruited. The patients were randomly divided into case and control groups. In the case group, TXA was administered directly under endoscopic therapy. In the control group, epinephrine (1/10,000) was submucosally injected to the four quadrants of ulcer margins as the routine endoscopic therapy. In both groups, the patients received supportive medical therapy with intravenous fluids and proton pump inhibitor drugs. Results: The mean ± standard deviation age of the children was 5 ± 2.03 years. Rebleeding occurred in 15 (11.4%) and 21 (9.8%) patients in the case and control groups, respectively (P = 0.50). The frequency of blood transfusion episodes (P = 0.06) and duration of hospital stay (P = 0.07) were not statistically different between the groups. Conclusion: Using topical TXA via endoscopic procedures may be effective in cases of GI bleedings caused by active bleeding ulcers. In order to establish this therapeutic effect, a large number of clinical studies are needed. PMID:27251517

    Background: Gastric ulcer is one of the most serious diseases. Most classic treatment lines produce adverse drug reactions. Therefore, this study aimed to investigate the protective effects of two natural extracts, namely ginger and marshmallow extracts, on indomethacin-induced gastric ulcer in rats. Materials and Methods: Animals were divided into five groups; a normal control group, an ulcer control group, and three treatment groups receiving famotidine (20 mg/kg), ginger (100 mg/kg), and marshmallow (100 mg/kg). Treatments were given orally on a daily basis for 14 days prior to a single intra-peritoneal administration of indomethacin (20 mg/kg). Results: Indomethacin administration resulted in significant ulcerogenic effect evidenced by significant elevations in ulcer number, ulcer index, and blood superoxide dismutase activity accompanied by significant decreases in gastric mucosal nitric oxide and glutathione levels. In addition, elevations in gastric mucosal lipid peroxides and histamine content were observed. Alternatively, pretreatment with famotidine, ginger or marshmallow significantly corrected macroscopic and biochemical findings, supported microscopically by results of histopathological study. Conclusion: These results demonstrate that administration of either ginger or marshmallow extract could protect against indomethacin-induced peptic ulcer in rats presumably via their antioxidant properties and inhibition of histamine release.

    Helicobacter pylori persistence in patients with chronic gastritis is associated with a complex of nonspecific structural reactions, the type of these reactions correlates with the severity of infection: catarrhal fibrotic changes in the gastric mucosa predominate in cases with manifest colonization, while the absence of H. pylori is associated with predominance of fibrotic process. Analysis of the incidence of some pathomorphological phenomena (degeneration, atrophy, metaplasia, and dysplasia of the surface epithelium) shows no relationship between the presence of H. pylori and colonization intensity. In all patients with chronic hepatitis, the gastric mucosa is involved in the pathological process; fibrosis (gastropathy) was the most common process. No appreciable correlations between the structural changes and hepatitis activity and the presence of H. pylori were detected.

    The clinical outcome of Helicobacter pylori infection may be associated with the cagA bacterial genotype. To investigate the cagA status of H. pylori-infected patients and the relationship between cagA and peptic ulcer disease, gastric biopsy specimens from 103 Caucasian patients in Brazil were analyzed by PCR. Since allelic variation in cagA exists and distinct H. pylori subgenotypes may circulate in different regions, PCR using primers for a variable 3′ region of the cagA gene according to a Japanese methodology and for a consensus cagA 3′ region used in Western methods was used for cagA detection. cagA was present in 53 (71%) of 75 H. pylori-positive cases when analyzed by the consensus region method and was associated with duodenal ulcer disease (P = 0.02), but not with gastric ulcer (P = 0.26), when compared to patients with duodenitis or gastritis. The variable region PCR method was able to detect 43 (57%) cagA-positive cases within the same group of H. pylori-positive patients and showed three subtypes of cagA (A, B/D, and C) that were not associated with clinical outcome. However, in 8 (18%) of the cases, more than one subtype was present, and an association between patients with multiple subtypes and disease outcome was observed when compared to patients with isolated subtypes (P = 0.048). cagA was a marker of H. pylori strains for duodenal ulcer disease in our population, and in spite of the differences in the 3′ region of the cagA gene, the Japanese methodology was able to detect the cagA status in most cases. The presence of multiple subgenotypes of cagA was associated with gastric ulcer. PMID:11158115

    This study evaluates in vivo and in vitro anti-Helicobacter pylori (H. pylori) efficacy of silver nanoparticles (Ag-NPs) prepared via a cost-effective green chemistry route wherein Peganum harmala L. seeds extract was used as a reducing and capping agent. The structural features, as elucidated by surface plasmon resonance spectrophotometry, transmission electron microscopy, and powder X-ray diffraction spectroscopy, revealed the Ag-NPs synthesized to be polydispersed in nature and spherical in shape with 5–40 nm size. A typical Ag-NPs suspension (S5), with size being 15 nm, when tested in vitro against forty-two local isolates and two reference strains, showed a considerable anti-H. pylori activity. In case of in vivo trial against H. pylori induced gastritis, after oral administration of 16 mg/kg body weight of S5 for seven days, a complete clearance was recorded in male albino rates. In comparative time-killing kinetics, S5 exhibited dose- and time-dependent anti-H. pylori activity that was almost similar to tetracycline and clarithromycin, less than amoxicillin, but higher than metronidazole. Furthermore, S5 was found to be an equally effective anti-H. pylori agent at low (≤4) and high pH with no drug resistance observed even up to 10 repeated exposures while a significant drug resistance was recorded for most of the standard drugs employed. The present results revealed the potential of the synthesized Ag-NPs as safer bactericidal agents for the treatment of H. pylori induced gastritis. PMID:25214825

    The extended monitoring (up to 1 year 11 months) of PCR markers was implemented concerning viral infections: cytomegalovirus, Epstein-Barr virus, simple herpes virus type I and II, hepatitis B virus, hepatitis C virus and bacterial infection of Helicobacter pylori in bioassays (blood, biopsy material of mucous coat of stomach and inferior third of esophagus) from children with different types of chronic gastritis. In biological samples from patients with gastritis type A and type A + B DNA of hepatitis B virus (87% and 71% of patients correspondingly) and DNA of Epstein-Barr virus (63% and 67% of patients) were detected with high rate. Under gastritis type B and C these markers were detected significantly rarely (20-36%). Among patients with gastritis type A, B and A + B, the positive results on DNA of cytomegalovirus consisted 13-17%. In patients with gastritis type C DNA of cytomegalovirus was not detected. In any of analyzed samples no DNA of simple herpes virus type I and II was detected. The control of DNA of H. pylori demonstrated its presence in biological materials of 67% and 84% of patients with gastritis type B and A +B. This type of DNA was absent in patients with gastritis type A and C. Under gastritis type A, B and A+B, DNA of Epstein-Barr virus and DNA of hepatitis B virus detected more often in biological materials of mucous coat of stomach (71%-100%) and out of them simultaneously in blood in 33%-60% of examined patients and only in blood up to 29%. DNA of Epstein-Barr virus was detected in leukocytes of peripheral blood and DNA of hepatitis B virus both in plasma and leukocytes of peripheral blood. Under gastritis type C DNA of Epstein-Barr virus was always detected in leukocytes of peripheral blood (in 20% out of these patients simultaneously in biological material) and DNA of hepatitis B virus just as much in blood (plasma and/or leukocytes of peripheral blood) and biological materials.

    The recognition that peptic ulcer is an infectious disease caused by the bacterium Helicobacter pylori has revolutionized the approach to diagnosis and therapy of this condition. Treatment of the symptoms of peptic ulcer with drugs that block acid secretion is already being replaced by antibiotic eradication of the causative agent. Studies of the molecular events that lead to H. pylori pathogenesis have shown that clinical isolates can be divided into two groups, only one of which produces a cytotoxin and is associated with severe disease. The cloning of the genes coding for molecules specific for disease-associated strains of H. pylori, and the development of animal models that mimic the human pathology, will provide the basis for better strategies to treat and prevent peptic-ulcer disease.

    2015-09-01

    An idiopathic peptic ulcer is defined as an ulcer with unknown cause or an ulcer that appears to arise spontaneously. The first step in treatment is to exclude common possible causes, including Helicobacter pylori infection, infection with other pathogens, ulcerogenic drugs, and uncommon diseases with upper gastrointestinal manifestations. When all known causes are excluded, a diagnosis of idiopathic peptic ulcer can be made. A patient whose peptic ulcer is idiopathic may have a higher risk for complicated ulcer disease, a poorer response to gastric acid suppressants, and a higher recurrence rate after treatment. Risk factors associated with this disease may include genetic predisposition, older age, chronic mesenteric ischemia, smoking, concomitant diseases, a higher American Society of Anesthesiologists score, and higher stress. Therefore, the diagnosis and management of emerging disease should systematically explore all known causes and treat underlying disease, while including regular endoscopic surveillance to confirm ulcer healing and the use of proton-pump inhibitors on a case-by-case basis.

    Patients who have rheumatic disease and who are undergoing long-term aspirin therapy have a high incidence of peptic ulcer disease. Whether it is possible to heal long-term aspirin-related peptic ulcer disease if aspirin intake is continued is unknown. Nine patients with rheumatic disease who were receiving long-term aspirin therapy and who had 15 endoscopically verified gastric and/or duodenal ulcers were studied. Patients were treated daily with 1,200 mg of cimetidine plus at least 120 mL of antacid (Mylanta II), while continuing aspirin therapy at the same dose and type. By eight weeks, 14 ulcers had healed. This study shows that some aspirin-associated peptic ulcers can be healed, despite continued aspirin intake, by intensive medical therapy aimed at lowering intragastric acidity.

    AIM: To study the effect of mucilage obtained from cladodes of Opuntia ficus-indica (Cactaceae) on the healing of ethanol-induced gastritis in rats. METHODS: Chronic gastric mucosa injury was treated with mucilage (5 mg/kg per day) after it was induced by ethanol. Lipid composition, activity of 5’-nucleotidase (a membrane-associated ectoenzyme) and cytosolic activities of lactate and alcohol dehydrogenases in the plasma membrane of gastric mucosa were determined. Histological studies of gastric samples from the experimental groups were included. RESULTS: Ethanol elicited the histological profile of gastritis characterized by loss of the surface epithelium and infiltration of polymorphonuclear leukocytes. Phosphatidylcholine (PC) decreased and cholesterol content increased in plasma membranes of the gastric mucosa. In addition, cytosolic activity increased while the activity of alcohol dehydrogenases decreased. The administration of mucilage promptly corrected these enzymatic changes. In fact, mucilage readily accelerated restoration of the ethanol-induced histological alterations and the disturbances in plasma membranes of gastric mucosa, showing a univocal anti-inflammatory effect. The activity of 5’-nucleotidase correlated with the changes in lipid composition and the fluidity of gastric mucosal plasma membranes. CONCLUSION: The beneficial action of mucilage seems correlated with stabilization of plasma membranes of damaged gastric mucosa. Molecular interactions between mucilage monosaccharides and membrane phospholipids, mainly PC and phosphatidylethanolamine (PE), may be the relevant features responsible for changing activities of membrane-attached proteins during the healing process after chronic gastric mucosal damage.

    In the present study, we tried to explore the mechanism of montelukast as an antiulcerogenic agent in pyloric ligation (PL) and water immersion stress (WIS) induced peptic ulcer. The ameliorative effects of montelukast (5, 10, and 20 mg/kg, p.o.) on gastric volume and total acidity were studied in PL model. We have investigated the alteration in the ulcerative index, thiobarbituric acid reactive substances, reduced glutathione, activity of myeloperoxidase, and total calcium level in both models. Estimation of DNA fragmentation by gel electrophoresis was also performed. Medium and higher doses of montelukast showed significant (p<0.05) ameliorative potential on all the above parameters as compared with omeprazole treated group. DNA fragmentation pattern clearly indicated the antiapoptotic effect of montelukast in preventing mucosal erosion in both models. Hence, the gastroprotective effect of montelukast may be attributed to its antisecretory, antioxidative along with its antiapoptotic effect.

    Postherpetic neuralgia is the most common complication of herpes zoster. Identifying predictors for postherpetic neuralgia may help physicians screen herpes zoster patients at risk of postherpetic neuralgia and undertake preventive strategies. Peptic ulcer has been linked to immunological dysfunctions and malnutrition, both of which are predictors of postherpetic neuralgia. The aim of this retrospective case-control study was to determine whether adult herpes zoster patients with peptic ulcer were at greater risk of postherpetic neuralgia. Adult zoster patients without postherpetic neuralgia and postherpetic neuralgia patients were automatically selected from a medical center's electronic database using herpes zoster/postherpetic neuralgia ICD-9 codes supported with inclusion and exclusion criteria. Consequently, medical record review was performed to validate the diagnostic codes and all pertaining data including peptic ulcer, Helicobacter pylori (H. pylori) infection and ulcerogenic medications. Because no standard pain intensity measurement exists, opioid usage was used as a proxy measurement for moderate to severe pain. In total, 410 zoster patients without postherpetic neuralgia and 115 postherpetic neuralgia patients were included. Multivariate logistic regressions identified 60 years of age and older, peptic ulcer and greater acute herpetic pain as independent predictors for postherpetic neuralgia. Among etiologies of peptic ulcer, H. pylori infection and usage of non-selective nonsteroidal anti-inflammatory drugs were significantly associated with the increased risk of postherpetic neuralgia; conversely, other etiologies were not significantly associated with the postherpetic neuralgia risk. In conclusion, 60 years of age and older, peptic ulcer and greater acute herpetic pain are independent predictors for postherpetic neuralgia in adult herpes zoster patients.

    Abstract To investigate osteoporosis risk in patients with peptic ulcer disease (PUD) using a nationwide population-based dataset. This Taiwan National Health Insurance Research Database (NHIRD) analysis included 27,132 patients aged 18 years and older who had been diagnosed with PUD (International Classification of Diseases, Ninth Revision, Clinical Modification [ICD-9-CM] codes 531–534) during 1996 to 2010. The control group consisted of 27,132 randomly selected (age- and gender)-matched patients without PUD. The association between PUD and the risk of developing osteoporosis was estimated using a Cox proportional hazard regression model. During the follow-up period, osteoporosis was diagnosed in 2538 (9.35 %) patients in the PUD group and in 2259 (8.33 %) participants in the non-PUD group. After adjusting for covariates, osteoporosis risk was 1.85 times greater in the PUD group compared to the non-PUD group (13.99 vs 5.80 per 1000 person-years, respectively). Osteoporosis developed 1 year after PUD diagnosis. The 1-year follow-up period exhibited the highest significance between the 2 groups (hazard ratio [HR] = 63.44, 95% confidence interval [CI] = 28.19–142.74, P < 0.001). Osteoporosis risk was significantly higher in PUD patients with proton-pump-inhibitors (PPIs) use (HR = 1.17, 95% CI = 1.03–1.34) compared to PUD patients without PPIs use. This study revealed a significant association between PUD and subsequent risk of osteoporosis. Therefore, PUD patients, especially those treated with PPIs, should be evaluated for subsequent risk of osteoporosis to minimize the occurrence of adverse events. PMID:27100415

    Since perforated peptic ulcer is uncommon in children proton pump inhibitor prophylaxis is not routinely recommended when children are treated with high dose steroids. We describe a case of perforated ulcer in a six-year-old patient with nephrotic syndrome treated with high dose prednisolone. Initially, ulcer was not suspected due to uncharacteristic symptoms. The child developed peritoneal signs and surgery revealed a perforated peptic ulcer in the stomach. We recommend treatment with proton pump inhibitors if children, who are treated with high dose steroids develop abdominal symptoms, which can be caused by an ulcus.

It was shown the more evident increase of myocardial infarction risk in associated pathology patients. Such results have to be caused by the special risk factor. As such factor we desided to study the hyperhomosysteinemia. During research there were discovered that the lowest vitamin B12 serum level and the highest homocysteine serum level have been registrated in associated pathology (ischemic heart disease and acid peptic disease according to long-term proton pump inhibitor use) patients. It was shown evident correlation between that changes and dyslipidemia.

    The purpose of the study was to determine the condition of the periodontal tissues in 80 children with various morphological forms of gastritis and duodenitis. The examination included determination of oral hygiene and periodontal status by the simplified Green-Vermillion index, Silness-Low index, papillary-marginal-alveolar index, gingival Muhlemann-Cowell bleeding index, Schiller-Pisarev iodine index. In children with chronic gastritis and duodenitis high incidence of chronic catarrhal gingivitis (85.0%) was revealed. At the same time it was pointed out that inflammation in the periodontal tissues correlated with changes in the gastroduodenal mucosa. In 65.4% of children with superficial gastritis and duodenitis, chronic catarrhal gingivitis (localized in 38.5% of cases, generalized in 26.9%) was observed. In 94.4% of all children with diffuse and erosive gastritis and duodenitis, chronic generalized catarrhal gingivitis was observed, and low oral hygiene level was revealed. The severity and duration of the underlying disease aggravated clinical manifestations of chronic catarrhal gingivitis in children with lesions of the upper gastrointestinal tract.

    Helicobacter pylori (H. pylori) gastritis may progress to high risk gastropathy and cancer. However, the pathological progression has not been characterized in detail. H. pylori induce persistent inflammatory infiltration. Neutrophils are unique in that they directly infiltrate into foveolar epithelium aiming the proliferative zone specifically. Neutrophilic proliferative zone foveolitis is a critical pathogenic step in H. pylori gastritis inducing intensive epithelial damage. Epithelial cells carrying accumulated genomic damage and mutations show the Malgun (clear) cell change, characterized by large clear nucleus and prominent nucleolus. Malgun cells further undergo atypical changes, showing nuclear folding, coarse chromatin, and multiple nucleoli. The atypical Malgun cell (AMC) change is a novel premalignant condition in high risk gastropathy, which may progress and undergo malignant transformation directly. The pathobiological significance of AMC in gastric carcinogenesis is reviewed. A new diagnosis system of gastritis is proposed based on the critical pathologic steps classifying low and high risk gastritis for separate treatment modality. It is suggested that the regulation of H. pylori-induced neutrophilic foveolitis might be a future therapeutic goal replacing bactericidal antibiotics approach.

    Only a few cases of contact allergic gastritis in patients with nickel allergy have been reported in the literature. We report a case of probable contact-allergic gastritis in a 46-year-old woman. Clinical examination revealed lichenoid mucosal lesions of the gums adjacent to a bridge and crowns that had been implanted several weeks previously. Since implantation, the patient suffered from gastrointestinal complaints including stomach pain. Gastroscopy and histological investigation of stomach biopsies showed eosinophilic gastritis. Patch testing done under the diagnosis of contact allergic stomatitis showed positive reactions to gold sodium thiosulphate, manganese (II) chloride, nickel (II) sulphate, palladium chloride, vanadium (III) chloride, zirconium (IV) chloride, and fragrances. The crowns and the bridge contained gold, palladium, and zirconium, hence they were replaced by titan-based dentition. Shortly after replacing the artificial dentition, all gastrointestinal symptoms resolved spontaneously without further treatment. Delayed-type allergy to components in the artificial dentition seem to have caused the gastritis.

    Helicobacter pylori (H. pylori) gastritis may progress to high risk gastropathy and cancer. However, the pathological progression has not been characterized in detail. H. pylori induce persistent inflammatory infiltration. Neutrophils are unique in that they directly infiltrate into foveolar epithelium aiming the proliferative zone specifically. Neutrophilic proliferative zone foveolitis is a critical pathogenic step in H. pylori gastritis inducing intensive epithelial damage. Epithelial cells carrying accumulated genomic damage and mutations show the Malgun (clear) cell change, characterized by large clear nucleus and prominent nucleolus. Malgun cells further undergo atypical changes, showing nuclear folding, coarse chromatin, and multiple nucleoli. The atypical Malgun cell (AMC) change is a novel premalignant condition in high risk gastropathy, which may progress and undergo malignant transformation directly. The pathobiological significance of AMC in gastric carcinogenesis is reviewed. A new diagnosis system of gastritis is proposed based on the critical pathologic steps classifying low and high risk gastritis for separate treatment modality. It is suggested that the regulation of H. pylori-induced neutrophilic foveolitis might be a future therapeutic goal replacing bactericidal antibiotics approach. PMID:24914362

    Background Fast eating or overeating can induce gastrointestinal diseases such as gastritis. However, the association between gastritis and speed of eating is unclear. The aim of this study was to determine whether eating speed is associated with increased risk of endoscopic erosive gastritis (EEG). Methods We carried out a cross-sectional study involving 10,893 adults who underwent a general health checkup between 2007 and 2009. Two groups, EEG patients and EEG-free patients, were compared by using the t-test and the chi-square test. Multiple logistic regression analyses were performed to investigate the association between eating speed and EEG. Results The group with EEG had a higher proportion of males, average age, body mass index, and percentages of current smokers and risky drinkers than those without EEG. After adjusting for anthropometric, social, and endoscopic parameters, the group with the highest eating speed (<5 min/meal) had 1.7 times higher risk for EEG than the group with the lowest eating speed (≥15 min/meal) (odds ratio, 1.71; 95% confidence interval, 1.20-2.45). Conclusion High eating speed is an independent risk factor for EEG. Our results indicate the need for further studies to clarify the role of eating speed in gastritis. PMID:26634096

    Helicobacter pylori (H. pylori) is the etiologic agent of gastritis; it has been estimated that 50 % of the world's population could be infected by this bacteria. Gastritis may progress to chronic atrophic gastritis, a condition associated with the development of gastric cancer (GC). Several matrix metalloproteases (MMP) and tissue inhibitors of MMPs (TIMP) as well as disintegrins and metalloproteases (ADAM) have been reported as being involved in gastritis. Among other processes, these protein families participate in remodeling the extracellular matrix, cell signaling, immune response, angiogenesis, inflammation and epithelial mesenchymal transition. This systematic review analyzes the scientific evidence surrounding the relationship between members of the MMP, TIMP and ADAM families and infection by H. pylori in gastritis, considering both in vitro and in vivo studies. Given the potential clinical value of certain members of the MMP, TIMP and ADAM families as molecular markers in gastritis and the association of gastritis with GC, the need for further study is highlighted.

    Helicobacter pylori infection triggers chronic inflammation of the gastric mucosa that may progress to gastric cancer. The hypoxia-inducible factors (HIFs) are the central mediators of cellular adaptation to low oxygen levels (hypoxia), but they have emerged recently as major transcriptional regulators of immunity and inflammation. No studies have investigated whether H. pylori affects HIF signaling in immune cells and a potential role for HIF in H. pylori-mediated gastritis. HIF-1 and HIF-2 expression was examined in human H. pylori-positive gastritis biopsies. Subsequent experiments were performed in naive and polarized bone marrow-derived macrophages from wild-type (WT) and myeloid HIF-1α-null mice (HIF-1(Δmyel)). WT and HIF-1(Δmyel) mice were inoculated with H. pylori by oral gavage and sacrificed 6 mo postinfection. HIF-1 was specifically expressed in macrophages of human H. pylori-positive gastritis biopsies. Macrophage HIF-1 strongly contributed to the induction of proinflammatory genes (IL-6, IL-1β) and inducible NO synthase in response to H. pylori. HIF-2 expression and markers of M2 macrophage differentiation were decreased in response to H. pylori. HIF-1(Δmyel) mice inoculated with H. pylori for 6 mo presented with a similar bacterial colonization than WT mice but, surprisingly, a global increase of inflammation, leading to a worsening of the gastritis, measured by an increased epithelial cell proliferation. In conclusion, myeloid HIF-1 is protective in H. pylori-mediated gastritis, pointing to the complex counterbalancing roles of innate immune and inflammatory phenotypes in driving this pathology.

  18. Efficacy and long-term outcome of gastritis therapy in cheetahs (Acinonyx jubatus).

    A prospective clinical trial evaluating efficacy and long-term outcome of treatments for lymphoplasmacytic gastritis in cheetahs (Acinonyx jubatus) was conducted. The study evaluated efficacy of 11 different antibiotic and antiinflammatory treatment protocols in 32 cheetahs (19 male, 13 female) for reducing gastric inflammation and Helicobacter colonization and monitored the course of disease through histologic grading of gastric biopsies. All cheetahs were biopsied up to I wk before treatment and then rebiopsied within 1 mo after treatment. Most animals were reassigned to a second treatment regimen within 6 mo. Each animal received from one to three treatments during the study period. After the trial, gastric biopsies were obtained from each cheetah annually until death or transfer from the facility to assess disease progression. The trial and follow-up period spanned 10 yr. At onset of the trial, all 32 cheetahs had some degree of gastritis, and 26 cheetahs (81%) were colonized with Helicobacter. Inflammatory lesions worsened regardless of treatment or the presence of Helicobacter. No treatment had a significant effect on inflammatory changes except the lansoprazole/clarithromycin/amoxicillin treatment group, which produced a short-term decrease in inflammation when compared to controls. Prednisone had no effect on gastric inflammation. Overall, 65% of colonized cheetahs were initially cleared of histologic evidence of Helicobacter by treatment, with short-term eradication occurring in 100% of the animals treated with omeprazole/clarithromycin/amoxicillin or tetracycline/metronidazole/Pepto-Bismol for 28 days. Long-term follow-up of treated animals in this study clearly demonstrated that these treatments had little effect on life-long progression of gastritis or on Helicobacter burden in individual cheetahs, although some treatments provided short-term reduction in gastritis and Helicobacter. These results provide evidence that Helicobacter alone is not the cause

    The aim of this work was to prepare a combined drug dosage form of famotidine (FAM) and quercetin (QRT) to augment treatment of gastric ulcer. FAM was prepared as freeze-dried floating alginate beads using ion gelation method and then coated with Eudragit RL100 to sustain FAM release. QRT was prepared as solid dispersion with polyvinyl pyrrolidone K30 to improve its solubility. Photo images and scanning electron microscope images of the prepared beads were carried out to detect floating behavior and to reveal surface and core shape of the prepared beads. Anti-ulcerogenic effect and histopathological examination of gastric tissues were carried out to investigate the effect of the combined drug formulation compared with commercial FAM tablets and FAM beads. Gastric glutathione (GSH), superoxide dismutase, catalase, tissue myeloperoxidase, and lipid peroxidation enzyme activities and levels in rat stomach tissues were also determined. Results revealed that spherical beads were formed with an average diameter of 1.64±0.33 mm. They floated immediately with no lag time before floating, and remained buoyant throughout the test period. Treatment with a combination of FAM beads plus QRT showed the absence of any signs of inflammation or hemorrhage, and significantly prevented the indomethacin-induced decrease in GSH levels (P<0.05) with regain of normal GSH gastric tissue levels. Also, there was a significant difference in the decrease of malondialdehyde level compared to FAM commercial tablets or beads alone (P<0.05). The combined formula significantly improved the myeloperoxidase level compared to both the disease control group and commercial FAM tablet-treated group (P<0.05). Formulation of FAM as floating beads in combination with solid dispersion of QRT improved the anti-ulcer activity compared to commercially available tablets, which reveals a promising application for treatment of peptic ulcer.

    This study aimed to investigate the antiulcer and antioxidant activities of myrtle berry seed aqueous extract (MBSAE) in a peptic ulcer model induced by ethanol in male Wistar rats. MBSAE is rich in total polyphenols, total flavonoids, and unsaturated fatty acids, particularly linoleic (18:2) and oleic (18:1) acids. MBSAE also exhibited in vitro antioxidant activity using 2,2-diphenyl-1-picrylhydrazyl (DPPH) (IC50 = 172.1 μg/mL) and superoxide anion (IC50 = 200.24 μg/mL) scavenging activities. In vivo, MBSAE provided dose-dependent protection against ethanol-induced gastric and duodenal macroscopic and histological alterations. Also, it inhibited secretory profile disturbances and lipid peroxidation, and preserved normal antioxidant enzyme activities and nonenzymatic antioxidant levels. More importantly, we showed that acute alcohol intoxication increased gastric and duodenal calcium, hydrogen peroxide, and free iron levels, whereas MBSAE treatment protected against intracellular mediator deregulation. In conclusion, we suggest that MBSAE has potent protective effects against alcohol-induced peptic ulcer in rat. This protection might be related in part to its antioxidant properties as well as its opposite effects on some studied intracellular mediators.

    Regarding the complications of peptic ulcer, a perforation remains the most important fatal complication. The aim of our retrospective study was to determine relations between postoperative morbidity and comorbid disease or perioperative risk factors in perforated peptic ulcer. In total, 239 patients who underwent emergency surgery for perforated peptic ulcer in Ege University General Surgery Department, between June 1999 and May 2013 were included in this study. The clinical data concerning the patient characteristics, operative methods, and complications were collected retrospectively. One hundred seventy-five of the 239 patients were male (73.2%) and 64 were female (26.8%). Mean American Society of Anesthesiologists (ASA) score was 1 in the patients without morbidity, but mean ASA score was 3 in the morbidity and mortality groups. Primary suture and omentoplasty was the selected procedure in 228 of the patients. Eleven patients underwent resection. In total, 105 patients (43.9%) had comorbidities. Thirty-seven patients (67.3%) in the morbidity group had comorbid diseases. Thirteen (92.9%) patients in the mortality group had comorbid diseases. Perforation as a complication of peptic ulcer disease still remains among the frequent indications of urgent abdominal surgery. Among the analyzed parameters, age, ASA score, and having comorbid disease were found to have an effect on both mortality and morbidity. The controversial subject in the present study is regarding the duration of symptoms. The duration of symptoms had no effect on mortality nor morbidity in our study.

    Abstract Vagus nerve may play a role in serum glucose modulation. The complicated peptic ulcer patients (with perforation or/and bleeding) who received surgical procedures with or without vagotomy provided 2 patient populations for studying the impact of vagus nerve integrity. We assessed the risk of developing type 2 diabetes in peptic ulcer patients without and with complications by surgical treatment received in a retrospective population study using the National Health Insurance database in Taiwan. A cohort of 163,385 patients with peptic ulcer and without Helicobacter pylori infection in 2000 to 2003 was established. A randomly selected cohort of 163,385 persons without peptic ulcer matched by age, sex, hypertension, hyperlipidemia, Charlson comorbidity index score, and index year was utilized for comparison. The risks of developing diabetes in both cohorts and in the complicated peptic ulcer patients who received truncal vagotomy or simple suture/hemostasis (SSH) were assessed at the end of 2011. The overall diabetes incidence was higher in patients with peptic ulcer than those without peptic ulcer (15.87 vs 12.60 per 1000 person-years) by an adjusted hazard ratio (aHR) of 1.43 (95% confidence interval [CI] = 1.40–1.47) based on the multivariable Cox proportional hazards regression analysis (competing risk). Comparing ulcer patients with truncal vagotomy and SSH or those without surgical treatment, the aHR was the lowest in the vagotomy group (0.48, 95% CI = 0.41–0.56). Peptic ulcer patients have an elevated risk of developing type 2 diabetes. Moreover, there were associations of vagus nerve severance and decreased risk of subsequent type 2 diabetes in complicated peptic ulcer patients. PMID:27930533

    Six captive cheetahs (Acinonyx jubatus) with severe gastritis diagnosed by gastric endoscopy and mucosal histopathology were treated with omeprazole, metronidazole, and amoxicillin for 3 wk. Endoscopic biopsies were performed before therapy, immediately after treatment, and 3, 7, and 19 mo after treatment. Macroscopic appearance of the stomach, histologic scoring of gastric inflammation, and the presence or absence of spiral bacteria were recorded. Spiral bacteria were absent histologically immediately after treatment but reappeared in endoscopic biopsies by 3 mo after treatment. Gastritis scores fluctuated widely during the trial but improved in five of six cheetahs by 3 mo after treatment. By 19 mo after treatment, scores were close to the pretreatment scores. Therapy with omeprazole, amoxicillin, and metronidazole was associated with temporary improvement in the degree and distribution of gastritis in some cheetahs with gastritis, suggesting that treatment may be warranted once severe gastric inflammation has been diagnosed.

    Korean Red Ginseng (KRG) is an herbal medicine prescribed worldwide that is prepared from Panax ginseng C.A. Meyer (Araliaceae). Out of ginseng's various components, ginsenosides are regarded as the major ingredients, exhibiting anticancer and anti-inflammatory activities. Although recent studies have focused on understanding the anti-inflammatory activities of KRG, compounds that are major anti-inflammatory components, precisely how these can suppress various inflammatory processes has not been fully elucidated yet. In this study, we aimed to identify inhibitory saponins, to evaluate the in vivo efficacy of the saponins, and to understand the inhibitory mechanisms. To do this, we employed in vitro lipopolysaccharide-treated macrophages and in vivo inflammatory mouse conditions, such as collagen (type II)-induced arthritis (CIA), EtOH/HCl-induced gastritis, and lipopolysaccharide (LPS)/D-galactosamine (D-GalN)-triggered hepatitis. Molecular mechanisms were also verified by real-time PCR, immunoblotting analysis, and reporter gene assays. Out of all the ginsenosides, ginsenoside Rc (G-Rc) showed the highest inhibitory activity against the expression of tumor necrosis factor (TNF)-[Formula: see text], interleukin (IL)-1[Formula: see text], and interferons (IFNs). Similarly, this compound attenuated inflammatory symptoms in CIA, EtOH/HCl-mediated gastritis, and LPS/D-galactosamine (D-GalN)-triggered hepatitis without altering toxicological parameters, and without inducing gastric irritation. These anti-inflammatory effects were accompanied by the suppression of TNF-[Formula: see text] and IL-6 production and the induction of anti-inflammatory cytokine IL-10 in mice with CIA. G-Rc also attenuated the increased levels of luciferase activity by IRF-3 and AP-1 but not NF-[Formula: see text]B. In support of this phenomenon, G-Rc reduced TBK1, IRF-3, and ATF2 phosphorylation in the joint and liver tissues of mice with hepatitis. Therefore, our results strongly suggest that

    Peptic ulcers are an extremely common condition, usually occurring in the stomach and proximal duodenum. However, cases of peptic ulcers accompanied with multiple complications are extremely rare and hard to treat. The present case reinforces the requirement for the early recognition and correct treatment of peptic ulcers accompanied with multiple complications. A 67-year-old man presented with recurrent abdominal pain, fever and melena. The laboratory results showed anemia (hemoglobin 62 g/l) and hypoproteinemia (23 g/l). Abdominal imaging examinations revealed stones in the gallbladder and right liver, with air in the dilated intrahepatic and extrahepatic bile ducts. Endoscopic retrograde cholangiopancreatography failed due to a deformed pylorus. The patient was finally diagnosed with peptic ulcers accompanied with gastrointestinal (GI) bleeding, pylorus obstruction and cholangitis secondary to a choledochoduodenal fistula during an emergency pancreatoduodenectomy, which was performed due to a massive hemorrhage of the GI tract. The patient recovered well after the surgery. PMID:26870237

    Acute Helicobacter pylori associated gastritis causes achlorhydria, a powerful stimulus to gastrin secretion. If H pylori infection is acquired primarily in early childhood, then the degree of hypergastrinaemia in seropositive children should be age dependent. Anti-Helicobacter antibodies and fasting gastrin concentrations were measured in 439 children aged 4 to 13 years attending hospital for routine day case surgery not connected with any gastrointestinal disorder. Thirty per cent were seropositive for H pylori. There was an inverse relationship between the fasting gastrin concentration and age; the mean fasting gastrin in children aged 4-5 years, 155 ng/l, was significantly higher than that seen in children aged 12-13 years, 90 ng/l. The more noticeable hypergastrinaemia seen in young children with H pylori associated gastritis may reflect achlorhydria associated with acute H pylori infection and suggests that this is primarily acquired in early childhood.

    Fifty dyspeptic patients with histologically proven chronic superficial antral gastritis were treated for 6 weeks, in a randomized single-blind study, with esaprazole (450 mg bid) or sulglicotide (200 mg tid). Both drugs significantly improved the symptomatic score after 3 and 6 weeks (p less than 0.01), and the percentual rate of improvement was similar in the two groups studied. Similarly, both treatments significantly reduced the inflammation of gastric mucosa. Drugs were ineffective in clearing Helicobacter pylori from the antral mucosa (as assessed by the urease test, performed at entry and after 6 weeks). No side effects occurred after esaprazole or sulglicotide administration. The results of the present study suggest that esaprazole, a new gastroprotective drug, may have a role in the therapy of dyspeptic patients with chronic superficial gastritis.

    A 76-year-old female patient was admitted to the Level I Emergency Department of University of Szeged with severe abdominal pain and vomiting. The clinical assessment with laboratory tests and radiological investigations confirmed severe sepsis associated with intravascular hemolysis and multiorgan failure and acute pancreatitis. On the abdominal CT, besides of other abnormalities, the presence of gas bubbles in the stomach, small intestines and liver were seen. The gastric alterations pointed to emphysematous gastritis. Despite of the medical treatment, the patient's condition quickly deteriorated and eight hours after admission the patient died. The autopsy evaluation revealed systemic infection of abdominal origin caused by gas-producing Gram-positive bacteria, and the post-mortem microbiological cultures confirmed the presence of Cloctridium perfringens in many abdominal organs. Emphysematous gastritis seemed to be the primary infectious focus.

    Emphysematous gastritis is a rare and frequently fatal condition caused by invasion of gas-forming bacteria into the gastric wall. There have only been a handful of reported cases in the paediatric population, and none of these have evidence of candidal infection or mucormycosis. Patients typically present with abdominal pain, vomiting, malaena and haematemesis. Risk factors for emphysematous gastritis are those that interfere with the natural barriers to infection in the stomach. Diagnosis is made on the basis of typical appearances on abdominal CT. Treatment is generally conservative with surgery reserved for failed medical management or later complications. Antimicrobial cover should be broad with a low threshold for antifungals. It is important to look for predisposing factors for this condition, perhaps including an assessment of the patient's immunocompetency. We present a 16-year-old boy with global developmental delay who presented with this condition associated with candidal infection.

    A 14-year-old athletic boy with a 1-year history of decreased exercise tolerance presented with unexplained iron deficiency anemia. Panendoscopy, colonoscopy, and barium contrast studies of the gastrointestinal tract were normal. However, persistent uptake of radionuclide using a 99mtechnetium-sucralfate scan suggested inflammation localized to the stomach. Mucosal biopsies demonstrated acute and chronic gastritis that was not associated with the presence of Campylobacter pylori.

    Twenty-four young adult domestic cats from a commercial vendor were found to be infected with Helicobacter pylori. Histopathologic analyses, selected electron microscopy, and urease mapping were performed on mucosal samples collected from the cardias and fundi, bodies, and antra of these cats' stomachs. H. pylori organisms were abundant in all areas of the stomach on the basis of histologic evaluation and urease mapping. H. pylori infection was associated with a moderate to severe lymphofollicular gastritis in 21 of 24 cats (88%). The gastritis was most pronounced in the antral region and consisted mainly of multifocal lymphoplasmacytic follicular infiltrates in the deep mucosa. The severity of gastritis in the antrum corresponded to high numbers of H. pylori there on the basis of the use of the urease assay as an indicator of H. pylori colonization. Ten of 24 cats (42%) also had small to moderate numbers of eosinophils in the gastric mucosa. All 24 cats had gastric lymphoid follicles, with follicles being most prevalent in the antrum. Electron microscopy of gastric tissue revealed numerous H. pylori organisms, some of which were closely adhered to the mucosal epithelium. Human H. pylori gene-specific primers to ureA and ureB amplified products of similar sizes from H. pylori cat isolates. Digestion of the products with restriction enzymes resulted in fragments characteristic of the restriction fragment length polymorphism patterns of H. pylori isolates from humans. In the domestic cat, H. pylori infection is associated with a lymphofollicular gastritis, consisting of lymphocytic and plasmacytic infiltration into the lamina propria, and the organism appears to provide chronic antigenic stimulation resulting in the formation of gastric lymphoid follicles.

    Autoimmune gastritis is often suspected for its hematologic findings, and rarely the diagnosis is made for the presence of gastrointestinal symptoms. Aims of this cross-sectional study were to assess in a large cohort of patients affected by autoimmune gastritis the occurrence and the pattern of gastrointestinal symptoms and to evaluate whether symptomatic patients are characterized by specific clinical features.Gastrointestinal symptoms of 379 consecutive autoimmune gastritis patients were systematically assessed and classified following Rome III Criteria. Association between symptoms and anemia pattern, positivity to gastric autoantibodies, Helicobacter pylori infection, and concomitant autoimmune disease were evaluated.In total, 70.2% of patients were female, median age 55 years (range 17-83). Pernicious anemia (53.6%), iron deficiency anemia (34.8%), gastric autoantibodies (68.8%), and autoimmune disorders (41.7%) were present. However, 56.7% of patients complained of gastrointestinal symptoms, 69.8% of them had exclusively upper symptoms, 15.8% only lower and 14.4% concomitant upper and lower symptoms. Dyspepsia, subtype postprandial distress syndrome was the most represented, being present in 60.2% of symptomatic patients. Univariate and multivariate analyses showed that age <55 years (OR 1.6 [CI:1-2.5]), absence of smoking habit (OR 2.2 [CI:1.2-4]), and absence of anemia (OR 3.1 [CI:1.5-6.4]) were independent factors associated to dyspepsia.Autoimmune gastritis is associated in almost 60% of cases with gastrointestinal symptoms, in particular dyspepsia. Dyspepsia is strictly related to younger age, no smoking, and absence of anemia.

    Altered gastro-duodenal motility seems to be a major factor of alkaline gastritis. Therefore prokinetic drugs have been extensively used for the treatment of this disease. Aim of this study has been to compare the effects of domperidone with those of a more recent drug of the orthopramide class, clebopride. Thirty patients affected by reflux gastritis have been randomly allocated to one of the two treatments. Clinical symptoms, endoscopic and histologic appearance of gastric mucosa, gastric pH and bile acid concentration in gastric juice have been evaluated before and after a four week course of therapy. A statistically significant improvement was observed for the clinical symptoms in the subjects treated with clebopride. Even if no statistical difference has been pointed out for the other parameters between and within the two groups, a slight trend in favour of clebopride was observed. It is concluded that clebopride is at least as effective as domperidone for the treatment of reflux gastritis but that more prolonged studies and different administration schedules are requested for a better evaluation.

    122 patients with osteoarthrosis, who have in the past medical history verified chronic gastritis (50 males and 72 females) at the age from 42 to 64 have been examined. Control group was comprised of 40 patients with osteoarthrosis without gastroduodenal zone pathology in the past medical history. For arthralgia relief patients were prescribed meloxicam (average dose--12.5 - 1.39 mg daily) or nimesulide (average dose--150 ± 14.91 mg daily). As a result of this research it was determined that administration of selective NSAID (meloxicam and nimesulide) in patients with chronic gastritis in the past medical history raised the risk of NSAID gastropathy/dyspepsia 2.9 times (P < 0.03) than in patients without associated gastroduodenal zone pathology. Atrophy of gastric mucosa is associated with higher risks (P > 0.05) of erosive gastropathy. Patients with chronic gastritis in the past medical history when taking NSAID with the purpose of gastropathy prevention are recommended to undergo gastroprotective therapy.

    Helicobacter pylori gastritis infection rate increases with age. Higher rates have however been reported among young people in the developing countries of the world. The infection however has rarely been reported in infants, especially in Africa. This case series describes three cases of Helicobacter pylori gastritis infection as diagnosed in three infants. The goal is to raise the suspicion index of medical practitioners about the possibility of this this infection among infants who present with suggestive symptoms. On three separate occasions in 2012 and 2013, three ill, indigenous, black African female infants aged 4, 6 and 7 months, were brought to hospital with symptoms ranging from fever, refusal to feed, diarrhoea, restlessness, vomiting and irritability. In each case, systemic examination findings were unremarkable. After several laboratory investigations, each infant was found to have Helicobacter pylori infection following positive blood antibody (using Tell Me Fast H. Pylori antibody serum and Plasma test manufactured by Biocan Diagnostics Canada) and fecal HpSA ImmunoCardSTAT antigen tests. Repeat stool antigen test was negative in each case after completion of the recommended triple therapy. Helicobacter pylori infection has been rarely reported among infants. This case series highlights the need for health care providers to have a high index of suspicion so that infants with suggestive symptoms, especially in settings with high Helicobacter pylori colonization prevalence can be evaluated for Helicobacter pylori gastritis infection.

  2. Gene polymorphism of interleukin 1 and 8 in chronic gastritis patients infected with Helicobacter pylori

    2014-01-01

    Background Epidemiological investigations have indicated that Helicobacter pylori induces inflammation in the gastric mucosa regulated by several interleukins. The genes IL1B and IL8 are suggested as key factors in determining the risk of gastritis. The aim of this paper was to evaluate the association of gene polymorphism of interleukin-1 and interleukin-8 with chronic gastrits in H. pylori infected patients. A total of 60 patients underwent endoscopic procedure. Biopsy samples were collected for urease test, histopathological and molecular exams. The DNA of theses samples was extracted for detection of H. pylori and analysis of the genes mentioned above. Patients with gastritis had a higher frequency of H. pylori-positive samples. Results H. pylori was detected in 30/60 patients (50%) by PCR. As for polymorphism of interleukin 8 (-251) gene we observed a statistical difference when analyzed TA (p = 0.039) and TT (p = 0.047) genotypes. In the IL1B31 there was a statistical difference in TT (p = 0.01) genotype and in the IL1B-511 there wasn’t any statistical difference. Conclusion Our results suggest a strong correlation between the presence of chronic gastritis and infection by H. pylori and that IL1B-31TT and IL8-251TT genotypes appear to act as protective factors against H. pylori infection while IL8-251TA genotype may comprise a risk factor for infection with this bacterium.

  5. The intriguing relationship of Helicobacter pylori infection and acid secretion in peptic ulcer disease and gastric cancer.

    PubMed

    Malfertheiner, P

    2011-01-01

    Helicobacter pylori infection induces chronic inflammation of the gastric mucosa and thus profoundly affects gastric physiology. In the acute phase of infection, gastric acid secretion is transiently impaired. The morphological damage of the gastric mucosa, changes in gastric hormone release, and disruption of neural pathways all contribute to influence gastric acid secretion in a distinct manner. Changes in gastric acid secretion, whether impaired or increased, are intimately related with the topographic phenotypes of gastritis and the presence of atrophy or absence of corpus atrophy. The interplay of gastritis phenotype and acid secretion are key determinants in disease outcomes. Corpus-predominant gastritis and corpus atrophy are accompanied by hypochlorhydria and carry the highest risk for gastric cancer, whereas antrum-predominant gastritis with little involvement of the corpus-fundic mucosa is associated with hyperchlorhydria and predisposes to duodenal ulcer disease.

    We have reviewed all endoscopies performed in our hospital between 1977 and 1986. During that period, 1337 endoscopies were performed to identify bleeding from peptic ulcers. Excluded were cases in which a predisposing factor was found, such as the use of ulcerogenic drugs. Also excluded were chronic or critically ill patients. The remaining 540 cases were reviewed. In 447 of those cases, the bleeding lesion was a duodenal ulcer, whereas, in 93 cases, a gastric ulcer was found (a ratio of 5:1). The seasonal variation in the incidence of bleeding from peptic ulcers was evaluated. We found a significant difference in bleeding in the cold and hot seasons, the incidence being significantly greater during the cold season (November until February). A similar pattern was found for bleeding from both duodenal and gastric ulcers.

    Helicobacter pylori (H. pylori) is known to be the prime factor of peptic ulcer disease as well as NSAID usage. Although medical treatment of the bacteria can eliminate the problem for more than 90% of the infected people but the cost of treatment is high then acid reducing gastric surgery still has a definite role. The prevalence of H. pylori in peptic ulcer perferation is still unknown also whether vagotomy and gastrectomy could eradicate H. pylori. Now laparoscopic surgery especially the simple repair of the perforation has became routinely used in many part of the world. So acid reducing gastric surgery is a good choice in chronic user of NSAID and also an option for people who have H. pylori infection.

    Helicobacter pylori has a major role in the pathogenesis of peptic ulcer disease. Cure of the infection is essential in ulcer healing, but an additional PPI therapy after completing eradication treatment is widespread in clinical practice. In the present work clinical studies evaluating peptic ulcer healing followed or not by PPI treatment after eradication therapy were analyzed. The results of these trials are concordant that only a minority of patients with duodenal ulcer would benefit from prolonged acid suppressive treatment, a successful eradication therapy (that counts for a large proportion) is sufficient. There are less data available concerning gastric ulcer: successful eradication is also essential to ulcer healing and to avoid relapse, however it seems that post-eradication PPI therapy might be beneficial.

    Epidemiological investigations indicated association of the Helicobacter pylori infections with the occurrence of inflammatory conditions of the gastric mucosa and development of chronic gastritis and intestinal type of gastric cancer. IL1A and IL1B genes have been proposed as key factors in determining risk of gastritis and malignant transformation. The aim of this paper was to evaluate association of interleukin-1 gene polymorphisms with chronic gastritis, atrophy, intestinal metaplasia, dysplasia and intestinal type of gastric cancer in H. pylori-infected patients. Patients subjected to analysis represent group of 144 consecutive cases that suffered from dyspepsia with coexisting infection of H. pylori and chronic gastritis, chronic atrophic gastritis, intestinal metaplasia, dysplasia or gastric cancer. Molecular studies involved analysis of -889C>T polymorphism of IL1A gene and +3954C>T polymorphism of IL1B gene. Statistical analysis of association of polymorphism -889C>T of gene IL1A with changes in gastric mucosa showed lack of significance, whereas +3954C>T polymorphism of IL1B gene showed significant association. Frequency of allele T of +3954C>T polymorphism of IL1B gene was higher in group of patients with chronic gastritis, atrophy, intestinal metaplasia, dysplasia or intestinal type of gastric cancer (32.1 %) as compared with population group (23 %), χ(2) = 4.61 and p = 0.03. This corresponds to odds ratio: 1.58, 95 % CI: 1.04-2.4. Our results indicate that +3954C>T polymorphism of IL1B gene increase susceptibility to inflammatory response of gastric mucosa H. pylori-infected patients and plays a significant role in the development of chronic gastritis, atrophy, intestinal metaplasia, dysplasia and the initiation of carcinogenesis.

    Although Helicobacter pylori (H. pylori ) infection is considered a key risk factor for atrophic gastritis, along with other environmental factors, it is still unclear which factor is involved in the development of atrophic gastritis among H. pylori-infected subjects. In the present cross-sectional study, therefore, we analyzed various dietary factors in relation to the presence of atrophic gastritis among H. pylori-infected subjects who participated in a health check-up program in a town in northeastern Japan. One thousand and seventy-one subjects (362 males and 709 females) who provided both self-administered validated food frequency questionnaires and blood samples were the basis for the study, and all of them were serologically positive for H. pylori immunoglobulin G (IgG) antibody. Among them, 663 (223 males and 440 females) were diagnosed as having atrophic gastritis on the basis of serum pepsinogen levels. Odds ratios (OR) and 95% confidence intervals (95% CI) were calculated based on tertile categories of subjects without atrophic gastritis, using logistic regression analysis. Among females, high consumptions of rice (OR = 1.6, 95% CI: 1.1-2.3), cod roe (OR = 1.5, 95% CI: 1.0-2.2) and cuttlefish (OR = 1.5, 95% CI: 1.0-2.3) were associated with a moderately increased risk of atrophic gastritis after adjustment for age (P for trend = 0.02 for these items). Among males, high consumptions of rice and miso soup showed a tendency toward an increased risk (P for trend = 0.12 and 0.13, respectively). Vegetables and fruits showed no association among either males or females. From these results, it is suggested that the dietary habits of consumers of traditional Japanese foods may play a role in the development of atrophic gastritis after H. pylori infection.

    This study investigated childhood physical abuse and ulcers in a regionally representative community sample. Age, race and sex were controlled for in addition to five clusters of potentially confounding factors: adverse childhood conditions, adult socioeconomic status, current health behaviors, current stress and marital status, and history of mood/anxiety disorders. Childhood physical abuse is associated with many negative physical and psychological adult health outcomes. Two recent studies demonstrate a potential link between childhood physical abuse and peptic ulcer disease in adulthood. The authors use regional data for the Canadian provinces of Manitoba and Saskatchewan from the 2005 Canadian Community Health Survey. Of the 13,069 respondents with complete data on abuse and ulcers, 7.3% (n = 1,020) report that they had been physically abused as a child by someone close to them and 3.0% (n = 493) report that they had been diagnosed with peptic ulcers by a health professional. The regional response rate is approximately 84%. Findings show that those reporting abuse had more than twice the prevalence of ulcers than did those not reporting abuse (6.6% vs. 2.7%). The fully adjusted odd ratio of peptic ulcers among those who had reported childhood physical abuse is 1.68 (95% CI = 1.22, 2.32). A significant and stable relationship between childhood physical abuse and peptic ulcers is found, even when taking into account five clusters of potentially confounding factors. Prospective studies that apply the biopsychosocial model are likely to be the most effective for identifying the pathways that connect childhood physical abuse and ulcer disease.

    Intramural hematoma of duodenum (IDH) is a relatively unusual complication associated with endoscopic treatment of bleeding peptic ulcer. This unusual condition is usually seen in children following blunt trauma to the abdomen. We describe here a case of IDH occurring following endoscopic therapy for bleeding duodenal ulcer in an adult patient with end-stage renal disease. The hematomas appeared on the second day of endoscopic intervention, caused transient duodenal obstruction and resolved spontaneously with conservative treatment in a week.

    To establish time trends in surgical rates for peptic ulcer disease, all surgical departments in Sweden were requested to complete a questionnaire regarding elective operations for gastric and duodenal ulcers and emergency operations for ulcer perforations performed in 1956, 1966, 1976, and 1986. A total of 8558 operations were reported for these years. The incidence of elective surgery declined steadily, the rates being 72.1, 45.0, 31.9, and 10.7 per 100,000 inhabitants. The male:female ratio fell from 4.2 to 1.5:1, while the duodenal/gastric ulcer ratio remained virtually unchanged. The operation rate for perforation decreased by 50%, from 12.8 to 6.4 per 100,000 inhabitants. We conclude that there has been a dramatic decline in elective peptic ulcer surgery in Sweden that began long before the advent of fiberoptic endoscopy, highly selective vagotomy, or H2-receptor antagonists. The comparable decline in emergency procedures suggests that true changes in the incidence or severity of the disease have occurred. In the future the few patients still needing elective surgery for peptic ulcer may have to be served by a small number of specialized centers. PMID:2589883

    Despite decreasing Helicobacter pylori prevalence, the prevalence of peptic ulcer disease is increasing in the aged population, mainly due to increasing use of NSAIDs to manage pain and inflammation. In addition, low dose aspirin is employed as an anti-coagulant for those who have suffered or are at high risk of ischemic stroke and cardiovascular disease. However, NSAIDs and aspirin are injurious to mucosa of stomach and duodenum. NSAID-induced inhibition of mucosal prostaglandin synthesis is thought to be a major mechanism of gastrointestinal mucosal injury. The proportion of elderly has increased rapidly in Korea, with the proportion over 65 years old expected to be 24.3% in 2030. In this higher-risk population, the strategy to reduce the incidence of NSAID-related peptic ulcers and complications such as bleeding, obstruction and perforation is very important. Proton pump inhibitors (PPIs) with cyclooxygenase-2 inhibitor can be used for reducing the risk of NSAID-related ulcers and upper gastrointestinal (GI) complications. However, continuous use of PPI has several problems. In addition, NSAID-related problems in the lower GI tract have increased, in contrast to the decrease of NSAID-related upper GI disease. The aim of this review is to provide an evidence-based knowledge regarding the mechanism, complications of treatment, and prevention strategies for NSAID- or aspirin-related peptic ulcer disease in Korea.

    We investigated over time whether contemporary Japanese patients with complicated peptic ulcers have any water-soluble vitamin deficiencies soon after the onset of the complicated peptic ulcers. In this prospective cohort study, fasting serum levels of water-soluble vitamins (vitamins B1, B2, B6, B12, C, and folic acid) and homocysteine were measured at 3 time points (at admission, hospital discharge, and 3 mo after hospital discharge). Among the 20 patients who were enrolled in the study, 10 consecutive patients who completed measurements at all 3 time points were analyzed. The proportion of patients in whom any of the serum water-soluble vitamins that we examined were deficient was as high as 80% at admission, and remained at 70% at discharge. The proportion of patients with vitamin B6 deficiency was significantly higher at admission and discharge (50% and 60%, respectively, p<0.05) than at 3 mo after discharge (10%). In conclusion, most patients with complicated peptic ulcers may have a deficiency of one or more water-soluble vitamins in the early phase of the disease after the onset of ulcer complications, even in a contemporary Japanese population.

    Over the past two decades, surgery for complicated peptic ulcer disease has evolved to a "less-is-more" approach due predominately to improved medical therapy. This study sought to determine whether a nonresective operative strategy has been an effective and prudent approach. A 20-year retrospective evaluation was conducted to compare outcomes of patients from the first decade (1990-1999) with those from the more recent decade (2000-2009). In all, 50 patients underwent surgery for complications of peptic ulcer disease, 36 in the early period and 14 in the later period, with 94 per cent being urgent or emergent. Acid-reducing procedures (vagotomy) decreased significantly from 29 to 7 over the two periods (P = 0.04), as did gastric resections from 23 to 3 (P = 0.01). The prevalence of H. pylori and use of NSAIDs both increased from 28 per cent to 36 per cent and 31 per cent to 43 per cent, respectively. Postoperative mortality remained unchanged, 22 per cent vs. 7 per cent (P = 0.41) over the two periods. Resections and definitive acid-reducing procedures continue to decline with no increase in adverse outcomes. This more moderate operative approach to complicated peptic ulcer surgery is appropriate given the trend towards lower mortality and improved medical treatment. In our high-risk veteran population, overall perioperative mortality, length of stay, and reoperations have been reduced.

    An idiopathic peptic ulcer is defined as an ulcer with unknown cause or an ulcer that appears to arise spontaneously. The first step in treatment is to exclude common possible causes, including Helicobacter pylori infection, infection with other pathogens, ulcerogenic drugs, and uncommon diseases with upper gastrointestinal manifestations. When all known causes are excluded, a diagnosis of idiopathic peptic ulcer can be made. A patient whose peptic ulcer is idiopathic may have a higher risk for complicated ulcer disease, a poorer response to gastric acid suppressants, and a higher recurrence rate after treatment. Risk factors associated with this disease may include genetic predisposition, older age, chronic mesenteric ischemia, smoking, concomitant diseases, a higher American Society of Anesthesiologists score, and higher stress. Therefore, the diagnosis and management of emerging disease should systematically explore all known causes and treat underlying disease, while including regular endoscopic surveillance to confirm ulcer healing and the use of proton-pump inhibitors on a case-by-case basis.

    Serological markers of gastritis, like pepsinogen A, pepsinogen C, gastrin, and Helicobacter pylori antibodies, can be used to explore the state of the gastric mucosa in populations with contrasting cancer risks. A decreasing pepsinogen A:C ratio and an increasing serum gastrin are known to reflect an increasing severity of atrophic corpus gastritis, which is a precursor of gastric cancer. In 723 subjects (without gastroduodenal surgery) from Japanese (n = 225) and Dutch (n = 498) working populations, which had a similar composition of age (mean 48 years), sex (male to female ratio 6:1), and type of occupation, fasting serum samples were analysed for IgG antibodies to H pylori, pepsinogen A, pepsinogen C, and gastrin in the same laboratory. H pylori infection was significantly more prevalent in the Japanese than in the Dutch (74.7% and 31.3%); as was a very low pepsinogen A, indicative of severe mucosal atrophy (4.4% and 1.6%). Among subjects with and without severe mucosal atrophy the H pylori seropositivity rate was similar. Between the Japanese and the Dutch there were significant differences in mean gastrin (31.8 and 13.4 pmol/l) and pepsinogen A:C ratio (1.7 and 2.9). These intercountry differences were as great for H pylori negative subjects (gastrin: 23.7 and 10.3 pmol/l, pepsinogen A:C ratio: 2.4 and 3.2) as for H pylori positive subjects (gastrin: 34.6 and 20.1 pmol/l, pepsinogen A:C ratio: 1.5 and 2.5). The intercountry difference in gastrin nearly disappeared after stratification into categories of pepsinogen A:C ratio. In conclusion, the intercountry differences in pepsinogen A:C ratio and gastrin reflect a higher prevalence of mild and severe mucosal atrophy of the corpus in the Japanese than in the Dutch, both among H pylori positive and negative subjects. Thus, these findings suggest that in the Japanese the development of atrophic gastritis is in part unrelated to H pylori. PMID:7557568

  19. Shuttle cloning and nucleotide sequences of Helicobacter pylori genes responsible for urease activity.

    Production of a potent urease has been described as a trait common to all Helicobacter pylori so far isolated from humans with gastritis as well as peptic ulceration. The detection of urease activity from genes cloned from H. pylori was made possible by use of a shuttle cosmid vector, allowing replication and movement of cloned DNA sequences in either Escherichia coli or Campylobacter jejuni. With this approach, we cloned a 44-kb portion of H. pylori chromosomal DNA which did not lead to urease activity when introduced into E. coli but permitted, although temporarily, biosynthesis of the urease when transferred by conjugation to C. jejuni. The recombinant cosmid (pILL585) expressing the urease phenotype was mapped and used to subclone an 8.1-kb fragment (pILL590) able to confer the same property to C. jejuni recipient strains. By a series of deletions and subclonings, the urease genes were localized to a 4.2-kb region of DNA and were sequenced by the dideoxy method. Four open reading frames were found, encoding polypeptides with predicted molecular weights of 26,500 (ureA), 61,600 (ureB), 49,200 (ureC), and 15,000 (ureD). The predicted UreA and UreB polypeptides correspond to the two structural subunits of the urease enzyme; they exhibit a high degree of homology with the three structural subunits of Proteus mirabilis (56% exact matches) as well as with the unique structural subunit of jack bean urease (55.5% exact matches). Although the UreD-predicted polypeptide has domains relevant to transmembrane proteins, no precise role could be attributed to this polypeptide or to the UreC polypeptide, which both mapped to a DNA sequence shown to be required to confer urease activity to a C. jejuni recipient strain.

    Seventy-two adult cheetahs were evaluated for the degree of gastritis by endoscopic biopsy and for renal disease by serum creatinine. Cheetahs free of Grade 3 gastritis and renal disease were placed on Trial A; remaining cheetahs were placed on Trial B, which ran concurrently. All cheetahs were monitored for 4 years. Cheetahs exited Trial A and entered Trial B if they developed Grade 3 gastritis or renal disease. Cheetahs exited Trial B if they developed clinical gastritis or renal disease that required a dietary change or aggressive medical therapy or died owing to either disease. Cheetahs on Trial A were fed either a supplemented meat diet (N = 26) or commercial cat food (N = 22). Cheetahs on Trial B were fed either the same meat diet (N = 28) or a commercial dry cat food formulated for renal disease (N = 16). Cheetahs fed meat on Trial A had a daily hazard of developing Grade 3 gastritis 2.21 times higher (95% CI 0.95-5.15) than cheetahs fed commercial cat food. This hazard was not statistically significant (P = 0.07). Mean gastritis scores were not significantly different between the two groups. Cheetahs fed commercial cat food in both Trials had lower serum urea levels and higher creatinine levels than those fed meat. Evidence for the effect of diet in cheetahs with gastritis and/or renal disease (Trial B) was inconclusive. The number of cheetahs dying of gastritis or renal disease at the facility has dropped markedly since the study began. These results indicate that diet may play an important role in the incidence of Grade 3 gastritis and that dietary and/or therapeutic management of gastritis may reduce mortality owing to gastritis and renal disease in captive cheetahs.

    In traditional Iranian medicine (TIM), several edible fruits and spices are thought to have protective and healing effects on peptic ulcer (PU). The present study was conducted to verify anti-PU activity of these remedies. For this purpose, edible fruits and spices proposed for the management of PU in TIM were collected from TIM sources, and they were searched in modern medical databases to find studies that confirmed their efficacy. Findings from modern investigations support the claims of TIM about the efficacy of many fruits and spices in PU. The fruit of Phyllanthus emblica as a beneficial remedy for PU in TIM has been demonstrated to have antioxidant, wound healing, angiogenic, anti-H. pylori, cytoprotective, antisecretory, and anti-inflammatory properties. The fruit of Vitis vinifera has been found to be anti-H. pylori, anti-inflammatory, wound healing, angiogenic, cytoprotective, and antioxidant. The fruit and aril of seed from Myristica fragrans exert their beneficial effects in PU by increasing prostaglandin, modulation of nitric oxide and inflammatory mediators, wound healing, antisecretory, antacid, antioxidant, and anti-H. pylori activities, and improving angiogenesis. Pharmacological and clinical studies for evaluation of efficacy of all TIM fruits and spices in PU and their possible mechanisms of action are recommended. PMID:24066235

    AIM: To determine the frequency of small bowel ulcerative lesions in patients with peptic ulcer and define the significance of those lesions. METHODS: In our prospective study, 60 consecutive elderly patients with upper gastrointestinal bleeding from a peptic ulceration (cases) and 60 matched patients with a non-bleeding peptic ulcer (controls) underwent small bowel capsule endoscopy, after a negative colonoscopy (compulsory in our institution). Controls were evaluated for non-bleeding indications. Known or suspected chronic inflammatory conditions and medication that could harm the gut were excluded. During capsule endoscopy, small bowel ulcerative lesions were counted thoroughly and classified according to Graham classification. Other small bowel lesions were also recorded. Peptic ulcer bleeding was controlled endoscopically, when adequate, proton pump inhibitors were started in both cases and controls, and Helicobacter pylori eradicated whenever present. Both cases and controls were followed up for a year. In case of bleeding recurrence upper gastrointestinal endoscopy was repeated and whenever it remained unexplained it was followed by repeat colonoscopy and capsule endoscopy. RESULTS: Forty (67%) cases and 18 (30%) controls presented small bowel erosions (P = 0.0001), while 22 (37%) cases and 4 (8%) controls presented small bowel ulcers (P < 0.0001). Among non-steroidal anti-inflammatory drug (NSAID) consumers, 39 (95%) cases and 17 (33%) controls presented small bowel erosions (P < 0.0001), while 22 (55%) cases and 4 (10%) controls presented small bowel ulcers (P < 0.0001). Small bowel ulcerative lesions were infrequent among patients not consuming NSAIDs. Mean entry hemoglobin was 9.3 (SD = 1.4) g/dL in cases with small bowel ulcerative lesions and 10.5 (SD = 1.3) g/dL in those without (P = 0.002). Cases with small bowel ulcers necessitate more units of packed red blood cells. During their hospitalization, 6 (27%) cases with small bowel ulcers presented

    The efficacy of various antimicrobial and anti-ulcer agents on the eradication of Campylobacter pylori in patients with antral gastritis or duodenal ulcers was investigated by several open studies or double-blind, placebo-controlled protocols. Among the anti-ulcer agents, ranitidine, cimetidine or sucraflate had no effect on C. pylori. Colloidal bismuth subcitrate achieved clearance of C. pylori in 40% of treated patients at the end of therapy but a high relapse rate (14/16 patients) was observed after a 6-month follow-up period. The antibacterial agents doxycycline, minocycline, ofloxacin, clindamycin, paromomycin and nifuroxazide failed to eradicate C. pylori in most patients. By contrast, short term elimination of C. pylori could be achieved in more than 90% of patients treated with amoxycillin. However, relapse occurred as a rule in all amoxycillin-treated patients within one month after therapy. Overall, we observed no correlation between the in-vitro activity of the different antibacterial agents and their in vivo efficacy. Development of resistance during therapy does not seem to account for this discrepancy since it occurred only with ofloxacin. On the basis of these results, we conclude that long term eradication of C. pylori from the gastric antrum cannot be achieved after monotherapy either with antibiotics or with bismuth salts.

    Persistent exacerbation of a peptic ulcer may lead to a complicated peptic ulcer (perforation or/and bleeding). The management of complicated peptic ulcers has shifted from acid-reducing vagotomy, drainage, and gastrectomy to simple local suture or non-operative (endoscopic/angiographic) hemostasis. We were interested in the long-term effects of this trend change. In this study, complicated peptic ulcer patients who received acid-reducing vagotomy were compared with those who received simple suture/hemostasis to determine the risk of ischemic heart disease (IHD).This retrospective cohort study analyzed 335,680 peptic ulcer patients recorded from 2000 to 2006 versus 335,680 age-, sex-, comorbidity-, and index-year matched comparisons. Patients with Helicobacter pylori (HP) infection were excluded. In order to identify the effect of vagus nerve severance, patients who received gastrectomy or antrectomy were also excluded. The incidence of IHD in both cohorts, and in the complicated peptic ulcer patients who received acid-reducing vagotomy versus those who received simple suture or hemostasis was evaluated.The overall incidence of IHD was higher in patients with peptic ulcer than those without peptic ulcer (17.00 vs 12.06 per 1000 person-years), with an adjusted hazard ratio (aHR) of 1.46 based on multivariable Cox proportional hazards regression analysis controlling for age, sex, Charlson's comorbidity index, and death (competing risk). While comparing peptic ulcer patients with acid-reducing vagotomy to those with simple suture/hemostasis or those without surgical treatment, the aHR (0.58) was the lowest in the acid-reducing vagotomy group.Patients with peptic ulcer have an elevated risk of IHD. However, complicated peptic ulcer patients who received acid-reducing vagotomy were associated with reduced risk of developing IHD.

    Collagenous gastritis (CG) is a rare disorder. Two patient groups are known: 1) Children and young adults, presenting with anaemia and abdominal pain, and 2) adults presenting with watery diarrhoea. In the latter group, CG is frequently associated with collagenous colitis and/or coeliac disease. This case concerns a 15-year-old boy with a bleeding ulcer. The biopsies from corpus ventriculi showed a thickened subepithelial collagen band (> 10 micrometres), and the patient was diagnosed with CG. Ulcers are rarely linked to CG. CG should be considered when ulcers are found in children and young adults.

Macroscopic changes of stomach were recorded and some of the worms collected. Based on number of parasites present in the stomach, they were divided into light infection, mild infection, and severe infection. Parasites were collected, and worms identification of the species was confirmed on the basis of light microscope examination with reference to keys. Tissues fixed in 3% glutaraldehyde, post-fixed in 1% osmium tetroxide and processed and plastic embedded; ultrathin sections of 60-70 nm were cut and stained with uranyl acetate and lead citrate; electron microscopic observations showed that, in light infection some changes were observed in gastric cells such as dilatation and vesiculation of the endoplasmic reticulum, large numbers of lipid granules, mitochondrial swelling, nuclear chromatin margination, and some nucleus showed washed out appearance. Other cells showed some alterations in mitochondria, dilatation of smooth endoplasmic reticulum, loss of both free and bound ribosomes, vesiculation in cytoplasm, and increase Golgi apparatus and secretory vesicles. The inflammatory cells including lymphocytes, macrophages, mast cells, and predominantly eosinophils were identified. In moderate infection, the cellular pattern of gastric mucosa replaced with inflammatory cells. The marked increase of macrophages and other inflammatory cell was observed. A particular finding in our study was the presence of globule leukocyte in the moderate stage. Moreover, scant formation and distribution of collagen fibers as well as fibroblasts were also noted. In severe infection, the most obvious observation was marked distribution

    Gastritis cystica profunda (GCP) is a rare condition caused by ectopic entrapment of gastric glands, probably secondary to the disruption of muscularis mucosae. GCP is often associated with gastric adenocarcinoma, and loss of the KCNE2 subunit from potassium channel complexes is considered a common primary target molecule leads to both GCP and malignancy. In this study, we, for the first time, analyzed the expression of KCNE2 in surgically excised tissue from human gastric cancer associated with GCP and confirmed that reduced KCNE2 expression correlates with disease formation.

    The aim of this retrospective study was to evaluate the presence of risk factors for a type 1 gastric neuroendocrine neoplasia in a large cohort of patients with chronic atrophic gastritis. The study design consisted of an Italian multicentre, retrospective analysis. The study included all consecutive patients with chronic atrophic gastritis with or without type 1 gastric neuroendocrine neoplasias followed at the participating centres. Two hundred and twenty-nine patients with chronic atrophic gastritis were enroled at the participating centres. A total of 207 patients (154 female, 53 males, median age: 56.0 years) were included in the final analysis. One hundred and twenty-six patients had chronic atrophic gastritis without a gastric neuroendocrine neoplasia and 81 had a chronic atrophic gastritis with type 1 gastric neuroendocrine neoplasia. The median Chromogranin A level, evaluated in 141 patients, was 52.0 U/L. At upper gastrointestinal endoscopy, atrophy of the gastric mucosa was mild/moderate in 137 patients and severe in 68. Intestinal metaplasia of the corpus was present in 168 patients. At histological examination, 81 patients had a gastric neuroendocrine neoplasia (42 patients had a NET G1 and 33 a NET G2). The median Ki67 index was 2.0 %. At univariate and multivariate analysis, the risk factors for a gastric neuroendocrine neoplasia were: male gender, chromogranin A greater than 61 U/L, presence of intestinal metaplasia and age equal to or greater than 59 years. Chromogranin A greater than 61 U/L, the presence of intestinal metaplasia and male gender were independent risk factors for a type 1 gastric neuroendocrine neoplasia in patients with chronic atrophic gastritis.

    The plastic hardener methyl ethyl ketone peroxide is unstable peroxide that releases free oxygen radicals. Ingestion of this compound induces widespread liver necrosis, severe metabolic acidosis, corrosive esophagitis and gastritis, that is often fatal. A 49-year-old man unintentionally ingested approximately 100 mL (55%) of this compound in solution, which was purchased as plastic hardener. Despite resuscitation, he died about 11 hours after admission. We report a patient with poisoning due to methyl ethyl ketone peroxide who presented with corrosive esophagitis and gastritis, gastrointestinal bleeding, and developed ischemia of the bowel and necrosis of the liver and died of severe metabolic acidosis and multiorgan failure.

    The aims of our study were to determine the prevalence of the babA2 gene within Helicobacter pylori strains circulating in the Slovenian pediatric population, to further clarify its significance in causing inflammation of gastric mucosa in children and to verify whether cagA, vacA, iceA and babA genes work independently or synergistically in causing gastritis. A total of 163 H. pylori isolates obtained from the same number of children were tested for the presence of cagA, vacA and iceA genes using previously established methods, while the babA2 gene was determined using novel polymerase chain reaction assay targeting a 139-bp fragment of the central region of babA2. The babA2 gene was detected in 47.9% of H. pylori samples. The presence of the babA2 gene was strongly associated with cagA, vacA s1 and vacA m1 genotype. The babA2 status correlated positively with bacterial density score, activity of inflammation and chronic inflammation of gastric mucosa. No significant correlation was found between the babA2 status and the presence of atrophy or intestinal metaplasia. In addition, the activity of gastric inflammation and density score were significantly associated with the coexpression of the cagA, vacA s1, vacA m1 and babA2 genes. The study, which included the largest number of pediatric H. pylori samples to date, confirmed that babA2 gene plays an important role in the pathogenesis of H. pylori gastritis in children. Furthermore, our results suggest that babA2, cagA and vacA s1 and m1 gene products may work synergistically in worsening the inflammation of gastric mucosa.

    Tri-potassium di-citrato bismuthate is a complex bismuth salt stable in colloidal form advocated for the treatment of peptic ulcer. Preliminary placebo-controlled trials in small numbers of ambulant patients with endoscopically proven peptic ulcer, strongly suggest that the compound accelerates the rate of healing of gastric and duodenal ulcer within 4 weeks of treatment. However, trials involving larger numbers of patients followed-up for longer periods are required before a clear verdict on the efficacy of tripotassium di-citrato bismuthate in gastric and duodenal ulcer can be given. There are no reliable data on the effect of the drug on ulcer recurrence rate. Side-effects are negligible and the drug could become an important therapeutic agent in peptic ulcer therapy if results of further study are conclusive. The drug causes dark discolouration of the stools and this should be borne in mind when considering the possibility of the presence of intestinal bleeding.

    AIM To investigate the long-term prognosis in peptic ulcer patients continuing taking antithrombotics after ulcer bleeding, and to determine the risk factors that influence the prognosis. METHODS All clinical data of peptic ulcer patients treated from January 1, 2009 to January 1, 2014 were retrospectively collected and analyzed. Patients were divided into either a continuing group to continue taking antithrombotic drugs after ulcer bleeding or a discontinuing group to discontinue antithrombotic drugs. The primary outcome of follow-up in peptic ulcer bleeding patients was recurrent bleeding, and secondary outcome was death or acute cardiovascular disease occurrence. The final date of follow-up was December 31, 2014. Basic demographic data, complications, and disease classifications were analyzed and compared by t- or χ2-test. The number of patients that achieved various outcomes was counted and analyzed statistically. A survival curve was drawn using the Kaplan-Meier method, and the difference was compared using the log-rank test. COX regression multivariate analysis was applied to analyze risk factors for the prognosis of peptic ulcer patients. RESULTS A total of 167 patients were enrolled into this study. As for the baseline information, differences in age, smoking, alcohol abuse, and acute cardiovascular diseases were statistically significant between the continuing and discontinuing groups (70.8 ± 11.4 vs 62.4 ± 12.0, P < 0.001; 8 (8.2%) vs 15 (21.7%), P < 0.05; 65 (66.3%) vs 13 (18.8%), P < 0.001). At the end of the study, 18 patients had recurrent bleeding and three patients died or had acute cardiovascular disease in the continuing group, while four patients had recurrent bleeding and 15 patients died or had acute cardiovascular disease in the discontinuing group. The differences in these results were statistically significant (P = 0.022, P = 0.000). The Kaplan-Meier survival curve indicated that the incidence of recurrent bleeding was higher in patients

    Prevalence of atrophic gastritis in various population of Siberia with serological tests was studied. Representative samples of Novosibirsk adult population and also urban and rural population of Yakutia were examined. 348 persons at the age more than 45 years (180 males and 168 females) were studied. Concentration of pepsinogen I, gastrin 17 and antibodies to Helicobacter pilori in blood serum was estimated with immune-enzyme analysis ("Biohit GastroPanel", "Biohit", Finland). In addition, domestic test-systems were used for detection cytotoxic (expressing CagA-protein) strains H. pylori. Level of markers (pepsinogen, gastrin, antibodies to Helicobacter pilori and antibodies to CagA H. pilori) in observing populations had no difference between males and females, and also did not depend on age. Occurrence of atrophy in body of stomach in Novosibirsk population, urban and rural population of Yakutia was 10.1, 16.7 and 25.6% respectively, and in antral part--10.7, 25.6 and 8.9% respectively. Total atrophy was registered in 1% in all groups. Helicobacter infection was detected in 78-88% of population. Domestic immune-enzyme test-systems were comparable with data of histological examination and demonstrated greater sensitivity at H. pylori detection vs. foreign. High prevalence of atrophic gastritis in various groups of Siberia population was noticed, which must be was bounded with great level of H. pylori infection in population.

Volume of gastric juice, number and size of ulcer, gastric malonaldehyde, gastric glutathione, gastric protein and serum thyroxine (T4) were measured. Significant increases both of number of gastric ulcer and malonaldehyde while decreases both of glutathione and protein levels in rats in groups III and IV in comparison with control group. While, insignificant increase were observed between control and both of groups II and VI. In rats, low thyroid hormone level increase stress gastritis, and this effect can be decreased by treatment with Nigella sativa PMID:21383883

    In this paper, we attempt to find a valid method to distinguish gastric cancer and atrophic gastritis. Auto-fluorescence and Raman spectroscopy of laser induced (514.5 nm and 488.0 nm) was measured. The serum spectrum is different between normal and cancer. Average value of diagnosis parameter for normal serum, red shift is less than 12 nm and Raman relative intensity of peak C by 514.5 nm excited is stronger than that of 488.0 nm. To gastric cancer, its red shift of average is bigger than 12 nm and relative intensity of Raman peak C by 514.5 nm excited is weaker than that by 488.0 nm. To atrophic gastritis, the distribution state of Raman peaks is similar with normal serum and auto-fluorescence spectrum's shape is similar to that of gastric cancer. Its average Raman peak red shift is bigger than 12 nm and the relative intensity of peak C by 514.5 excited is stronger than that of by 488.0. We considered it as a criterion and got an accuracy of 85.6% for diagnosis of gastric cancer compared with the result of clinical diagnosis.

    Background Autoimmune gastritis (AIG) and adenocarcinoma-associated chronic atrophic gastritis (CAG) are both associated with oxyntic atrophy, but AIG patients demonstrate an increased risk of carcinoid tumors rather than the elevated risk of adenocarcinoma observed with CAG. We therefore sought to compare the characteristics of the metaplastic mucosa in AIG and CAG patients. Methods We examined markers for metaplasia (spasmolytic polypeptide expressing metaplasia (SPEM) and intestinal metaplasia) as well as proliferation (Ki67) and immune cell populations (neutrophils, macrophages, and eosinophils) in gastric sections from 16 female patients with autoimmune thyroiditis and AIG and 17 patients with CAG associated with gastric adenocarcinoma. Results Both AIG and CAG patients demonstrated prominent SPEM and intestinal metaplasia. However, AIG patients displayed significantly lower numbers of infiltrating macrophages and significantly reduced mucosal cell proliferation as compared to CAG patients. Conclusions These findings indicate that, while both AIG and CAG patients display prominent oxyntic atrophy and metaplasia, the AIG patients do not show proliferative metaplastic lineages that would predispose to adenocarcinoma.

    Chronic atrophic gastritis (CAG) is a well-established precursor of intestinal gastric cancer, but epidemiologic data about its occurrence are sparse. We provide an overview on studies that examined the prevalence of CAG in different parts of the world. Articles containing data about the prevalence of chronic atrophic gastritis in unselected population samples and published until November 2005 were identified by searching the MEDLINE database. Furthermore, the references in the identified publications were screened for additional suitable studies. Studies comprising at least 50 subjects were included. Forty-one studies providing data on the prevalence of CAG in unselected population samples could be identified. CAG was determined by gastroscopy in 15 studies and by pepsinogen serum levels in 26 studies. Although results are difficult to compare due to the various definitions of CAG used, a strong increase with age, the lack of major gender differences, and strong variations between populations and population groups (in particular, relatively high rates in certain Asian populations) could be observed quite consistently. We conclude that CAG is relatively common among older adults in different parts of the world, but large variations exist. Large-scale international comparative studies with standardized methodology to determine CAG are needed to provide a coherent picture of the epidemiology of CAG in various populations. Noninvasive measurements of CAG by pepsinogen levels may be particularly suited for that purpose.

    BACKGROUND AND AIM: Peptic ulcer disease (PUD) affects 10% of the world population. Helicobacter pylori infection and the use of a nonsteroidal anti-inflammatory drug (NSAID) are the principal factors associated with PUD. The aim of the present study was to evaluate a cohort of patients with PUD and determine the association between H pylori infection and NSAID use. PATIENTS AND METHODS: The medical charts of patients with endoscopic diagnosis of PUD were retrospectively reviewed from September 2002 to August 2003. Patients were divided into three groups according to ulcer etiology: H pylori infection (group 1); NSAID use (group 2); and combined H pylori infection and NSAID use (group 3). RESULTS: One hundred two patients were evaluated: 36 men (35.3%) and 66 women (64.7%). Forty patients had H pylori infection, 43 had used NSAIDs and 15 had combined H pylori infection and NSAID use; four patients with ulcers secondary to malignancy were excluded. The frequency of women was significantly higher in group 2 (P=0.01). The mean age of patients in group 1 was significantly lower than in the other two groups (P=0.003). PUD developed earlier in group 3 than in group 2 (5.0±4.7 months versus 1.4±2.1 months, respectively, P=0.018). Thirty-two patients (32.7%) had bleeding peptic ulcer. Group 2 had a higher risk of bleeding peptic ulcer than the other two groups (P=0.001). CONCLUSIONS: The development of PUD was observed earlier in the combined H pylori and NSAID group than in patients with only NSAID use. This suggests a synergic effect between the two risks factors in the development of PUD. PMID:16609757

    Although there is broad consensus about the benefits of proton pump inhibitors in acute upper peptic bleeding, there is still controversy over their optimal dosing. Searching in Epistemonikos database, which is maintained by screening 30 databases, we identified six systematic reviews including 27 randomized trials addressing this question. We combined the evidence using meta-analysis and generated a summary of findings table following the GRADE approach. We concluded high-dose proton pump inhibitors probably result in little or no difference in re-bleeding rate or mortality. The risk/benefit and cost/benefit balance probably favor use of low-doses.

    Neonatal thymectomy (NTx) induces autoimmune gastritis (AIG) in BALB/c mice, a model for human type A chronic atrophic gastritis, but not in DBA/2 mice and rarely in CDF1 mice (a hybrid of BALB/c and DBA/2 mice). The aim of this study was to clarify the mechanisms of AIG-resistance in mice bearing the dominant trait of DBA/2. Linkage groups associated with, and cells related to AIG resistance were examined with CDF1-BALB/c backcrosses. Intracellular staining and flow-cytometric bead array for several cytokines were performed on NTx BALB/c mice and NTx DBA/2-chimeric BALB/c mice receiving DBA/2-bone marrow cells. In NTx BALB/c mice, IFN-γ-secreting CD4(+) T cells were increased, but not in NTx DBA/2 mice. Because Vβ6(+) T cell-bearing mice of half of their backcrosses developed AIG, but the other half of Vβ6(+) T cell-negative mice developed scarcely, resistance for AIG generation is associated with the presence of the Mls-1a locus on chromosome 1 in DBA/2 mice, which deletes Vβ6(+) T cells. NTx DBA/2-chimera BALB/c mice showed dominant production of IL-10 and resistance for AIG, although the deletion of Vβ6(+) T cells was found not to be a cause of AIG-resistance from Mls-1a locus segregation experiments. Although NTx DBA/2-chimeric BALB/c mice did not suffer from AIG, they brought immediate precursors of T cells for AIG. It is concluded that DBA/2 mice generate bone marrow-derived cells that produce anti-inflammatory cytokines to prevent the activation of AIG-T cells.

To investigate the correlation between CD4+/CD8+ T-cells in gastric mucosa with endoscopic appearance in chronic gastritis with or without H.pylori infection. Prospective, cross sectional study is performed in a chronic dyspepsia population in July-November 2009 at Dr. Sardjito General Hospital Yogyakarta, Indonesia. The update Sydney system was used to analyze the gastroscopy appearance. Biopsy specimens were stained with HE-stain and IHC-stain. Data were analyzed by t-test, Mann-Whitney and Spearman correlation test. Number of 88 consecutive subjects are enrolled the study (50% male; 50% female), age 46±15 years; 25% H.pylori positive. The expression of CD4+ and CD8+ were higher in H.pylori negative subjects, but only the CD4+ was significant (P=0.011). A significant correlation was found between CD4+ and CD8+ in both subjects (r(Hp+)=0.62 and r(Hp-)=0.68; P<0.05). The expression of CD4+ and CD8+ in H.pylori positive showed a significant correlation with gastric lesions (r(CD4+)=-0.60; r(CD8+)=-0.42 ; P<0.05), only erosion showed a significant difference in both subjects. A positive correlation was found between CD4+ and CD8+ infiltration in both subjects with or without H.pylori infection, and a negative correlation was only found between gastric lesion with CD4+ and CD8+ infiltration in H.pylori subject.

    Serum pepsinogen I and II are considered as indicators of changes in gastric morphology. Important publications from the last decades are reviewed with regard to the serum level of these biomarkers for the diagnosis of normal gastric mucosa, diffuse gastritis and its change to atrophic gastritis and intestinal metaplasia as well as gastric cancer. Due to the low sensitivity of serum biomarkers for diagnosis of gastric cancer, especially at its early stage and the poor prognosis of the tumor at the time of diagnosis, its prevention by eradication of H. pylori remains the mandatory strategy. On the other hand, the severity of regression and non-reversibility of precancerous lesions and intestinal metaplasia in gastric mucosa through eradication of H. pylori make it necessary to diagnose diffuse gastritis at its early stage. Increased serum pepsinogen II compared to normal serum pepsinogen I seems to indicate the presence of diffuse gastritis without precancerous lesions suitable for eradication of H. pylori infection, when it is serologically positive. A diagram illustrates the strategy of this therapeutic measure depending on the age of people and the level of serum biomarkers in areas with high gastric cancer prevalence.

    Helicobacter pylori is one of the main causes of atrophic gastritis and gastric carcinogenesis. Gastritis can also occur in the absence of H. pylori as a result of bile reflux suggesting the eradication of H. pylori by bile acids. However, the bile salts are unable to eradicate H. pylori due to their low solubility and instability at acidic pH. This study examined the effect of a highly soluble and acid stable ursodeoxycholic acid (UDCA) formula on H. pylori-induced atrophic gastritis. The H. pylori infection decreased the body weight, mitochondrial membrane potential and ATP level in vivo. Surprisingly, H. pylori-induced expression of malate dehydrogenase (MDH), a key enzyme in the tricarboxylic acid cycle, at both the protein and mRNA levels. However, the UDCA formula repressed MDH expression and increased the membrane potential thereby increasing the ATP level and body weight in vivo. Moreover, UDCA scavenged the reactive oxygen species (ROS), increased the membrane potential, and inhibited apoptosis in AGS cells exposed to H(2)O(2) in vitro through the mitochondria-mediated pathway. Taken together, UDCA decreases the MDH and ROS levels, which can prevent apoptosis in H. pylori-induced gastritis.

    Neurofibromatosis type 1 is an autosomal dominant neurocutaneous disorder with characteristic features of skin and central nervous system involvement. Gastrointestinal complications are rare, especially during childhood. In adults, only two cases of peptic ulcer have been reported in neurofibromatosis, both due to Zollinger-Ellison syndrome. Peptic ulcer disease (PUD) may be primary or secondary in nature and it may be life threatening in the acute phase due to the risk of perforation. A case of recurrent gastrointestinal hemorrhage in a child with systemic neurofibromatosis and primary ciliary dyskinesia (PCD) is presented. The upper gastrointestinal endoscopy revealed the presence of multiple gastric ulcers. The ulcers scarred after the long-term administration of a proton pump inhibitor (PPI), but recurred after the suspension. Laboratory and imaging studies excluded Zollinger-Ellison syndrome and other known causes of PUD, suggesting a potential role of neurofibromatosis itself and primary ciliary dyskinesia in developing of recurrent PUD. As early diagnosis of PUD is vital for patient survival, this case report highlights the possible association of neurofibromatosis and PCD with this condition, responsive to PPI therapy and the potential need of gastric protection before complications arise.

    Peptic ulcer disease (PUD) and gastroesophageal reflux disease (GERD) are not uncommon in elderly patients. Clinical presentations of these acid-related disorders may be atypical in the geriatric population. Older individuals are at increased risk for poor outcomes in complicated PUD and for development of GERD complications. Multiple risk factors (eg, Helicobacter pylori [HP], use of nonsteroidal anti-inflammatory drugs [NSAIDs], aspirin) contribute to the development of PUD. Recent data has shown that HP-negative, NSAID-negative idiopathic peptic ulcers are on the rise and carry a higher risk of recurrent ulcer bleeding and mortality. Effective management of PUD in the geriatric population relies on identification and modification of treatable risk factors. Elderly patients with GERD often require long-term acid suppressive therapy. Proton pump inhibitors (PPI) including esomeprazole are effective in the treatment of reflux esophagitis, maintenance of GERD symptomatic control, and management of PUD as well as its complications. Potential safety concerns of long-term PPI use have been reported in the literature. Clinicians should balance the risks and benefits before committing elderly patients to long-term PPI therapy.

    An epizootic of subclinical lymphoplasmacytic gastritis occurred in cynomolgus monkeys maintained at our research facility. Gastric pathology data and histologic sections of 63 adolescent monkeys (2.5-3.5 years old) sacrificed during the epizootic were reviewed. Localized to multifocal reddening of the gastric mucosa was noted grossly in 7 of 44 (16%) monkeys harboring Helicobacter pylori, but not in any of 19 monkeys in which these bacteria were not seen. Gastritis, characterized by accentuation of lymphoplasmacytic infiltrates in antral and to a lesser degree cardiac mucosa, occurred in 42 of 63 (67%) monkeys evaluated and in 42 of 44 (93%) monkeys in which H. pylori was observed microscopically. Two monkeys with H. pylori infection had infiltrate scores that overlapped with the upper limit of scores of H. pylori-negative animals. Coincident with accentuated infiltrates were gastric gland epithelial hyperplasia, reduction in mucin content of surface and gland epithelia, and comparatively minor infiltrates of neutrophils in superficial lamina propria and gastric glands. Antral mucosa thickness often exceeded 1.5 to 2 times normal. Antral mucosal erosions occurred in 7 of 44 (16%) monkeys with H. pylori. Argyrophilic bacteria morphologically consistent with H. pylori were present in antral and less commonly cardiac mucosal glands. Intensity of bacterial colonization correlated with lymphoplasmacytic infiltrates (r = 0.754) and hyperplasia (r = 0.700), although responses were quite variable. These bacteria were not detected in fundic mucosa except in instances where parietal cells were substantially depleted in glands coincident with localized increases in lamina propria inflammatory cell infiltrates. Helicobacter heilmannii-like organisms (HHLOs) were present in fundic glands of all 63 monkeys; colonization was often pronounced. Scores for fundic mucosal inflammation did not correlate with presence or intensity of colonization with HHLOs (r = 0.005). Rather, fundic

    Helicobacter pylori (H. pylori) is a human gastric pathogen that has been linked to the development of several gastric pathologies, such as gastritis, peptic ulcer, and gastric cancer. In the gastric epithelium, the bacterium modifies many signaling pathways, resulting in contradictory responses that favor both proliferation and apoptosis. Consistent with such observations, H. pylori activates routes associated with cell cycle progression and cell cycle arrest. H. pylori infection also induces the hypoxia-induced factor HIF-1α, a transcription factor known to promote expression of genes that permit metabolic adaptation to the hypoxic environment in tumors and angiogenesis. Recently, however, also roles for HIF-1α in the repair of damaged DNA and inhibition of gene expression were described. Here, we investigated signaling pathways induced by H. pylori in gastric cells that favor HIF-1α expression and the consequences thereof in infected cells. Our results revealed that H. pylori promoted PI3K/mTOR-dependent HIF-1α induction, HIF-1α translocation to the nucleus, and activity as a transcription factor as evidenced using a reporter assay. Surprisingly, however, transcription of known HIF-1α effector genes evaluated by qPCR analysis, revealed either no change (LDHA and GAPDH), statistically insignificant increases SLC2A1 (GLUT-1) or greatly enhance transcription (VEGFA), but in an HIF-1α-independent manner, as quantified by PCR analysis in cells with shRNA-mediated silencing of HIF-1α. Instead, HIF-1α knockdown facilitated G1/S progression and increased Cyclin D1 protein half-life, via a post-translational pathway. Taken together, these findings link H. pylori-induced PI3K-mTOR activation to HIF-1α induced G0/G1 cell cycle arrest by a Cyclin D1-dependent mechanism. Thus, HIF-1α is identified here as a mediator between survival and cell cycle arrest signaling activated by H. pylori infection.

    Background/Aims The resistance rate of Helicobacter pylori is gradually increasing. We aimed to evaluate the efficacy of levofloxacin-based third-line H. pylori eradication in peptic ulcer disease. Methods Between 2002 and 2014, 110 patients in 14 medical centers received levofloxacin-based third-line H. pylori eradication therapy for peptic ulcer disease. Of these, 88 were included in the study; 21 were excluded because of lack of follow-up and one was excluded for poor compliance. Their eradication rates, treatment regimens and durations, and types of peptic ulcers were analyzed. Results The overall eradiation rate was 71.6%. The adherence rate was 80.0%. All except one received a proton-pump inhibitor, amoxicillin, and levofloxacin. One received a proton-pump inhibitor, amoxicillin, levofloxacin, and clarithromycin, and the eradication was successful. Thirty-one were administered the therapy for 7 days, 25 for 10 days, and 32 for 14 days. No significant differences were observed in the eradication rates between the three groups (7-days, 80.6% vs 10-days, 64.0% vs 14-days, 68.8%, p=0.353). Additionally, no differences were found in the eradiation rates according to the type of peptic ulcer (gastric ulcer, 73.2% vs duodenal/gastroduodenal ulcer, 68.8%, p=0.655). Conclusions Levofloxacin-based third-line H. pylori eradication showed efficacy similar to that of previously reported first/second-line therapies. PMID:27609487

    Vagus nerve may play a role in serum glucose modulation. The complicated peptic ulcer patients (with perforation or/and bleeding) who received surgical procedures with or without vagotomy provided 2 patient populations for studying the impact of vagus nerve integrity. We assessed the risk of developing type 2 diabetes in peptic ulcer patients without and with complications by surgical treatment received in a retrospective population study using the National Health Insurance database in Taiwan.A cohort of 163,385 patients with peptic ulcer and without Helicobacter pylori infection in 2000 to 2003 was established. A randomly selected cohort of 163,385 persons without peptic ulcer matched by age, sex, hypertension, hyperlipidemia, Charlson comorbidity index score, and index year was utilized for comparison. The risks of developing diabetes in both cohorts and in the complicated peptic ulcer patients who received truncal vagotomy or simple suture/hemostasis (SSH) were assessed at the end of 2011.The overall diabetes incidence was higher in patients with peptic ulcer than those without peptic ulcer (15.87 vs 12.60 per 1000 person-years) by an adjusted hazard ratio (aHR) of 1.43 (95% confidence interval [CI] = 1.40-1.47) based on the multivariable Cox proportional hazards regression analysis (competing risk). Comparing ulcer patients with truncal vagotomy and SSH or those without surgical treatment, the aHR was the lowest in the vagotomy group (0.48, 95% CI = 0.41-0.56).Peptic ulcer patients have an elevated risk of developing type 2 diabetes. Moreover, there were associations of vagus nerve severance and decreased risk of subsequent type 2 diabetes in complicated peptic ulcer patients.

    The role of gastrin on the development of atrophic gastritis (AG) and its relationship with the expression of RegIα  in vivo remain unclear. We established experimental AG in rats by combination administration with sodium salicylate, alcohol, and deoxycholate sodium. The mean score of inflammation in gastric antrum in AG rats was significantly elevated (P < 0.05), while the number of glands dramatically decreased (P < 0.05). In addition, the cell proliferation in gastric glands was increased in experimental AG rats, as determined by immunohistochemistry staining of PCNA and GS II. The level of serum gastrin in AG rats was significantly elevated relative to that of normal rats (P < 0.01). Moreover, the expression of RegIα protein and its receptor mRNA was increased in gastric tissues in AG rats (P < 0.05). Taken together, we demonstrated that the overexpression of Reglα is related with hypergastrinemia in AG rats. PMID:21949663

    The efficiency of transcutaneous magneto-laser treatment as a component of combined therapy of chronic gastritis in children and adolescents (aged 5-17 years) was compared with that of pharmacotherapy and low-intensity laser therapy. The patients were allocated to three groups of 25 persons each. Patients of group 1 were given only drug therapy, those in group 2 were treated with pharmaceuticals and low-intensity laser therapy. The patients comprising group 3 were subjected to the action of magneto-laser radiation. Magneto-laser therapy was shown to result in a significantly more expressed improvement of clinical and morphological characteristics of the patients compared with pharmacotherapy alone. There was no significant difference between effects of magneto-laser and low-intensity laser radiation.

    Helicobacter pylori infection induces chronic gastritis and lowers gastric juice ascorbic acid concentrations. We investigated how H. pylori eradication affected multiple variables that could prevent or delay development of new or occult gastric cancer in patients with early gastric cancer treated by endoscopic mucosal resection. Gastric juice pH, nitrite concentrations, and total vitamin C concentrations, serum concentrations of vitamin C and specific H. pylori antibody, and intensity of neutrophil infiltration in gastric mucosa were determined before and after successful H. pylori eradication. Successful eradication increased acid output and ascorbic acid secretion into gastric juice, accompanied by disappearance of polymorphonuclear infiltration from the surface epithelium and decreased gastric juice nitrite concentrations. Our data suggest that H. pylori eradication decreases the nitrosation rate as the ratio of vitamin C to nitrite increases. This decreases reactive oxygen species and nitric oxide, eliminating their damaging effect on DNA and reducing cell turnover.

    A causal relationship between oxyntic glands dilatation with protruding parietal cells, referred to as proton pump inhibitor (PPI) effects, and PPI use has been suspected but not established. We designed this study to evaluate the association between these changes and the use of PPIs and histamine2-receptor blockers (H2-blockers). We obtained five Sydney System-compliant biopsy specimens from patients recruited into a therapeutic trial for H. pylori. Medication history with details on PPI and H2-blockers use was collected. Two blinded pathologists graded gastritis and the intensity of putative PPI effects using a 0 to 3 scale. PPI and H2-blocker use was then disclosed and the accuracy of pathologists' assessment was analyzed. There were 138 H. pylori-negative and 104 positive patients. In H. pylori-negative patients the histologic assessment for PPI use had 77.5% sensitivity and 51.8% specificity, with a positive predictive value of 86.9% and a negative predictive value of 35.9%. In H. pylori-positive patients, sensitivity was 74.1% and specificity 26.1%. Positive and negative predictive values were 55.8% and 44.4%, respectively. Neither glandular dilatations nor parietal cell protrusions related to H2-blocker use. We conclude that these changes are associated with PPI use only in H. pylori-negative subjects. In H. pylori gastritis, so-called PPI-effects were equally prevalent in PPI-users and non-users, indicating that other factors are involved in the induction of oxyntic cell hyperplasia. We suggest that comments regarding the supposed evidence of PPI use are too often wrong to be useful and should be avoided in the diagnosis of gastric biopsy specimens.

    The objective of this study was to analyze the histopathological patterns of inflammation, distribution, severity, and degree of gastric mucosa of Helicobacter pylori (Hp)-infected children in Northern Mexico, as well as the correlation between colonization density and inflammation intensity. We carried out a cross-sectional study of gastric biopsies performed on children ranging from 2 to 17 years of age who underwent upper gastrointestinal endoscopy for diverse gastroduodenal disorders. This study includes only children who were found to be Hp carriers, with positive results for tests of Hp antigens in feces and in gastric biopsy studies. We studied 107 patients (age 8.2 ± 3.7 years). In 47.7% of patients, the density of Hp colonization was low; only 21.5% had a marked density. Mononuclear leukocyte infiltration showed a similar distribution. Thirty-seven percent of patients had follicular gastritis. An acute inflammatory response was absent in 65% and mild in 20.6% of patients. When inflammation was present, it was primarily located in the antrum (79%). There were no cases of intestinal metaplasia or atrophy. A link was found between Hp density and age, infiltration by mononuclear cells, the presence of follicular gastritis, and the level of neutrophil infiltration (P  =  0.001). Despite the high rates of Hp infection in the region, the histopathological findings in these children were mild and were limited primarily to the antral mucosa. These data indicate the need to study the behavior of this disease in children in diverse study populations to provide localized prevention and treatment strategies.

    Introduction Administrative healthcare databases are useful to investigate the epidemiology, health outcomes, quality indicators and healthcare utilisation concerning peptic ulcers and gastrointestinal bleeding, but the databases need to be validated in order to be a reliable source for research. The aim of this protocol is to perform the first systematic review of studies reporting the validation of International Classification of Diseases, 9th Revision and 10th version (ICD-9 and ICD-10) codes for peptic ulcer and upper gastrointestinal bleeding diagnoses. Methods and analysis MEDLINE, EMBASE, Web of Science and the Cochrane Library databases will be searched, using appropriate search strategies. We will include validation studies that used administrative data to identify peptic ulcer disease and upper gastrointestinal bleeding diagnoses or studies that evaluated the validity of peptic ulcer and upper gastrointestinal bleeding codes in administrative data. The following inclusion criteria will be used: (a) the presence of a reference standard case definition for the diseases of interest; (b) the presence of at least one test measure (eg, sensitivity, etc) and (c) the use of an administrative database as a source of data. Pairs of reviewers will independently abstract data using standardised forms and will evaluate quality using the checklist of the Standards for Reporting of Diagnostic Accuracy (STARD) criteria. This systematic review protocol has been produced in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocol (PRISMA-P) 2015 statement. Ethics and dissemination Ethics approval is not required given that this is a protocol for a systematic review. We will submit results of this study to a peer-reviewed journal for publication. The results will serve as a guide for researchers validating administrative healthcare databases to determine appropriate case definitions for peptic ulcer disease and upper gastrointestinal

    Introduction Peptic ulcer is a common disease that affects millions of people worldwide. Considering its global prevalence finding new approach for treating is important. Aim The aim of this study was to investigate the effect of zinc sulfate on gastric and duodenal ulcer treatment. Materials and Methods This double-blind clinical trial study was done on 90 patients who were admitted to the gastrointestinal endoscopy clinic of Tohid hospital in Sanandaj, Iran. All patients were diagnosed with gastric and duodenal ulcers. They were randomly divided into two-intervention and control groups, using block randomization with block sizes of 4. Patients and researcher were unaware of the grouping. To assess the level of zinc, blood samples were taken. In case of positive Rapid Urease Test (RUT), triple therapy regimen including amoxicillin, clarithromycin and omeprazole was administered for two weeks. For intervention group in addition to "triple therapy", an oral dose of Zinc Sulfate 220mg capsules were administered daily, while the control group received placebo capsules. Results A total of 54.5% and 57% of the patients in the intervention and control groups had gastric ulcer respectively. The Rapid Urease Test (RUT) result of 72.7% of intervention group and 83.3% of control group was positive (p = 0.24). Serum zinc level of 20.9% of intervention group and 35.7% of control group was lower than the normal level (p = 0.13). The mean of serum zinc level of intervention group and control group were 81.9 and 78.9 mg dL respectively (p = 0.4). After intervention, peptic ulcer in 81.8% of the intervention group and 83.3% of the control groups were improved (p= 0.85). Response to treatment were higher in patients with normal zinc levels compared to patients with abnormal levels (77.5% vs. 22.5%, p=0.019). Conclusion A daily dose of 220mg zinc sulfate was not significantly effective on peptic ulcer. However, patients with normal zinc levels had better ulcer treatment. PMID

    A close association has been established between climate and peptic ulcer bleeding (PUB). The incidence of PUB in cold climates is significantly higher than that in hot climates. In this study, gastric mucosal damage and its barrier function (through associated barrier factors) in extreme climate conditions were examined to investigate the pathogenesis of PUB in extreme cold climates. Gastric juice and biopsy specimens were collected from 176 patients with peptic ulcer. Conventional hematoxylin and eosin staining was used to exclude malignant ulcers. Helicobacter pylori infections were detected by modified Giemsa staining. pH values of the gastric juice samples were obtained on-site by precise pH dipstick readings. The protein expression levels of heat shock protein (HSP) 70, occludin, nitric oxide synthase (NOS), epidermal growth factor (EGF) and EGF receptor (EGFR) in the gastric mucosa were detected by immunohistochemistry. No significant differences were identified between the high and low bleeding risk groups in the rates of H. pylori infection and the pH values of the gastric juices in the extreme hot or cold climates. Furthermore, no statistically significant differences were identified in the protein expression levels of occludin, NOS, EGF and EGFR between the high and low bleeding risk groups. In the extreme cold climate, the expression of HSP70 and the mucus thickness of the gastric antrum in the high bleeding risk group were significantly lower than those in the low bleeding risk group. The protein expression levels of occludin, HSP70, NOS and EGFR in the extreme cold climate were significantly lower than those in the extreme hot climate, whereas the gastric acid secretion was significantly higher in the extreme cold climate than that in the extreme hot climate. In conclusion, low expression of HSP70 in the gastric mucosa and reduced gastric mucus thickness may play key roles in the mechanism of PUB in extreme cold climates. The significant decrease in

    Collagenous gastritis is a rare condition characterized by surface epithelial damage, subepithelial collagen deposition, and a lamina propria inflammatory infiltrate. Previous studies have proposed 2 clinicopathologic subtypes: (1) children (18 y of age or younger) presenting with severe anemia, nodular gastric mucosa, and isolated gastric disease; and (2) adults with chronic watery diarrhea that is associated with diffuse collagenous involvement of the gastrointestinal tract. However, notable exceptions exist. In fact, broad variability in clinical presentation, etiology, treatment and disease course has been reported. To better define the clinicopathologic features of collagenous gastritis, we have collected 10 pediatric and 21 adult cases and describe their clinical, endoscopic, pathologic, and follow-up findings. Both children and adults presented with similar clinical symptoms such as anemia (50%, 35%, respectively), epigastric/abdominal pain (50%, 45%), and diarrhea (40%, 55%). Concomitant immune disorders were identified in 2 (20%) children and 3 (14%) adults. Further, 7 of 17 (41%) adults were taking medications associated with other immune-related gastrointestinal diseases including olmesartan and antidepressants. Histologically, there were no differences between children and adults with collagenous gastritis in the location of gastric involvement, mean collagenous layer thickness, and prominence of eosinophils (P>0.05). Extragastric collagenous involvement was also seen with comparable frequencies in each cohort (44%, 59%). Follow-up information was available for 22 of 31 (71%) patients and ranged from 2 to 122 months (mean, 33.6 mo). Despite medical management in most cases, persistence of symptoms or collagenous gastritis on subsequent biopsies was seen in 100% of children and 82% of adults. Of note, treatment for 1 adult patient involved cessation of olmesartan resulting in resolution of both symptoms and subepithelial collagen deposition on subsequent

    Non-Helicobacter pylori, non-NSAID peptic ulcer disease (PUD), termed idiopathic PUD, is increasing in Korea. Diagnosis is based on exclusion of common causes such as H. pylori infection, infection with other pathogens, surreptitious ulcerogenic drugs, malignancy, and uncommon systemic diseases with upper gastrointestinal manifestations. The clinical course of idiopathic PUD is delayed ulcer healing, higher recurrence, higher re-bleeding after initial ulcer healing, and higher mortality than the other types of PUD. Genetic predisposition, older age, chronic mesenteric ischemia, cigarette smoking, concomitant systemic diseases, and psychological stress are considered risk factors for idiopathic PUD. Diagnosis of idiopathic PUD should systematically explore all possible causes. Management of this disease is to treat underlying disease followed by regular endoscopic surveillance to confirm ulcer healing. Continuous proton pump inhibitor therapy is an option for patients who respond poorly to the standard ulcer regimen.

  7. Helicobacter pylori virulence genes and host genetic polymorphisms as risk factors for peptic ulcer disease.

    Helicobacter pylori infection plays an important role in the pathogenesis of peptic ulcer disease (PUD). Several factors have been proposed as possible H. pylori virulence determinants; for example, bacterial adhesins and gastric inflammation factors are associated with an increased risk of PUD. However, differences in bacterial virulence factors alone cannot explain the opposite ends of the PUD disease spectrum, that is duodenal and gastric ulcers; presumably, both bacterial and host factors contribute to the differential response. Carriers of the high-producer alleles of the pro-inflammatory cytokines IL-1B, IL-6, IL-8, IL-10, and TNF-α who also carry low-producer allele of anti-inflammatory cytokines have severe gastric mucosal inflammation, whereas carriers of the alternative alleles have mild inflammation. Recent reports have suggested that the PSCA and CYP2C19 ultra-rapid metabolizer genotypes are also associated with PUD.

    The therapeutic agent colloidal bismuth subcitrate (CBS) selectively binds to peptic ulcers. The authors have developed a method for labeling this agent with Tc-99m. Chromatographic quality control studies of the agent on silica gel coated strips (ITLC-SG) showed that more than 97% of Tc-99m was bound to CBS. During in-vitro stability testing, the radio-label was stable for a minimum of 6 hours. The chromatographic findings are in agreement with the in-vivo distribution of the agent which showed no significant radioactivity in thyroid, kidneys, liver, or bladder. The resulting Tc-99m-CBS solution is administered orally in drinking water. Preliminary animal studies have been conducted on 5 adult 3 kg New Zealand rabbits sedated with 50 mg Ketamine I.M. The rabbits were intubated with I.V. tubing advanced to the stomach. They were given a gastric erosive suspension of 600-1000 mg/kg of pulverized ASA in 10 cc tap water. Four hours later they were given 3-4 mCi of the radiotracer in a 5 cc volume of water. Serial in-vivo images were obtained for 2 hours which included thyroid, abdomen, and urinary bladder. Next the stomachs were excised, opened along the greater curvature, imaged, vigorously washed and reimaged. All 5 rabbits showed avid localized binding of radiotracer which remained fixed even with vigorous washing. Areas of normal appearing mucosa were relatively devoid of radiotracer. This new compound may have significant clinical usefulness in the detection of peptic ulcer disease. In addition, such a non-invasive technique, carrying none of the risks or discomfort of endoscopy could also find application in the evaluation of the response to therapy.

    The relationship between ABO blood group distribution and Peptic Ulcer Disease (PUD) has been widely evaluated in the past. But data concerning the same evaluation are very limited in Iran. This study sought to determine the distribution of ABO blood group in patients with PUD in Iranian subjects. Eighty-one patients with PUD (51 male and 30 female; mean age: 49 +/- 18 years) who attended our endoscopy section were enrolled. Blood samples were used for ABO/Rhesus (Rh) blood group antigen typing. The ABO blood group phenotype distribution in subjects was as follows: 37.1% (30/81) for group A, 23.4% (19/81) for group B, 35.6% (28/81) for group O and 4.9% (4/81) for group AB. Rh positivity was found in 63% (51/81) of patients. In local healthy population, ABO/Rh blood group distribution was 33.8, 20.7, 34.7, 8.4 and 89.6% for A, B, O, AB and Rh, respectively. AB blood group distribution in healthy population was higher than PUD (8.4 vs 4.9%). In contrast, Rh positivity of PUD in Iran is lower than healthy subjects (63 vs 89.6%). Variation in the results of studies is related to different study communities. According to these results, probably ABO/Rh blood group has an important role in patients with peptic ulceration. The functional significance of ABO blood group distribution might be associated with biological behavior of PUD. The impact of blood group on PUD may be a focus for further studies.

    BACKGROUND Although Helicobacter pylori and non-steroidal anti-inflammatory drugs (NSAIDs) are the main causes of peptic ulcers disease (PUD), recently the prevalence of idiopathic peptic ulcer (IPU) is increasing in most parts of the world. The aim of this study was to assess the prevalence of IPU in Kerman, the center of largest province in south-east Iran. METHODS We included 215 patients with peptic ulcer in our study. Combined methods rapid urease test (RUT), histology, and real time polymerase chain reaction (PCR) was performed on endoscopic samples of peptic ulcers. NSAID use was determined by medical history. SPSS software version 16 was used for data analysis. p value<0.05 was considered as statistically significant. RESULTS Of 215 consecutive patients with peptic ulcer, four (1.8%) had H.pylorinegative and NSAID-negative PUD. There were not significant differences between patients with IPU and patients with peptic ulcer associated with H.pylori or NSAIDs regarding the sex, age, cigarette smoking, and opioid abuse. CONCLUSION Our study showed that in contrast to other reports from western and some Asian countries, the prevalence of IPU is low in Kerman and H.pylori infection is still the major cause of PUD. We recommend a large and multi-central study to determine the prevalence of IPU in Iran.

    AIM: Helicobacter pylori causes gastric mucosal inflammation and immune reaction. However, the increase of IL-10, MMP-7, and MMP-7 levels in the serum is still controversial. The objective of this study was to investigate the serum levels of IL-10, MMP-7 & MMP-9 in gastritis patients with H. pylori infection. MATERIALS AND METHODS: A cross-sectional study was done on seventy gastritis patients that consecutive admitted to endoscopy units. The diagnosis of gastritis was made based on histopathology and diagnosis of H. pylori infection was based on rapid urease test. Serum samples were obtained to determine to circulate IL-10, MMP-7, and MMP-9 level. Univariate and bivariate analysis were done by SPSS version 22. RESULTS: Forthy percentages of the patients were infected with H. pylori. The IL-10 level was significantly higher in H. pylori-infected patients compared to non-infected patients. However, there were no differences between serum levels of MMP-7 and MMP-9 in infected and non-infected H. pylori patients. CONCLUSIONS: The immune response to H. pylori promotes systemic inflammation, which was reflected by the increased levels of serum IL-10. However, there were no significant differences in MMP-7 and MMP-9 serum levels between positive and negative infected H. pylori patients. PMID:27703556

    Common variable immunodeficiency (CVID) is associated with an increased risk of gastric cancer. The aim of the study was to determine the morphological features of CVID-associated gastric adenocarcinoma (CAGA) and of the background gastritis. The population of gastric cancer patients with CVID of Mayo Clinic in the period 2000-2010 was studied; 6 cases of CVID (2 males, 4 females, average age 47 years, age range 26-71 years) were found in 5793 patients with gastric cancer in the study period. Each patient underwent gastric resection for which histology slides were reviewed. Chronic gastritis variables, CVID-related findings, and features of the adenocarcinoma were recorded. CAGA was of intestinal type, with high number of intratumoral lymphocytes (ITLs). Cancer was diagnosed in younger patients than in the overall population of gastric cancer. Severe atrophic metaplastic pangastritis with extensive dysplasia was present in the background in 4 cases, with features of lymphocytic gastritis in 2 cases. Features of CVID (plasma cells paucity in 4 of 6 cases, lymphoid nodules prominent in four cases) could be detected. In summary, gastric adenocarcinoma at young age with ITLs, accompanied by atrophic metaplastic pangastritis, should alert the pathologist of the possibility of CAGA. It follows that, in presence of those characteristics, the search of CVID-associated abnormalities should be undertaken in the nonneoplastic tissues.

    AIM: To determine the efficacy and safety of DA-9601 on erosive gastritis versus cetraxate as a standard drug by gastrointestinal endoscopy. METHODS: Five hundred and twelve patients with erosive gastritis were divided into three groups. The groups received 180 mg or 360 mg of DA-9601, or 600 mg of cetraxate (NeuerTM) t.i.d. for 2 wk, respectively. Endoscopic observations were performed before and 2 wk after the treatment, and the cure and improvement rates were investigated. RESULTS: Of the 512 intention-to-treat (ITT) population, 457 patients comprised the per protocol (PP) analysis. Endoscopic cure rate was significantly higher in the DA-9601 group than in the cetraxate group in both the PP (56%, 58% vs 36%; DA-9601 180 mg, 360 mg and cetraxate, respectively) and ITT (52%, 51% vs 35%) populations. Two DA-9601 groups (180 and 360 mg) had significantly higher endoscopic improvement rates than the cetraxate group in both the PP (67%, 65% vs 46%) and ITT (63%, 58% vs 45%) populations. The percentage of symptom relief over the 2 wk was found not significantly different between groups. During the study, both DA-9601 and cetraxate produced no treatment-associated adverse events. CONCLUSION: From these results, it appears that DA-9601 has excellent efficacy on erosive gastritis. This study also confirms the safety profile of DA-9601. PMID:15285023

    This study was conducted to assess the relationship between occurrence of gastric cancer and peptic ulcer, and the presence of H. pylori cagA gene and anti-CagA IgG, and to estimate the value of these antibodies in detecting infection by cagA gene-positive H. pylori strains in Saudi patients. The study included 180 patients who were subjected to upper gastrointestinal endoscopy in Taif province and Western region of Saudi Arabia (60 gastric cancer, 60 peptic ulcer, and 60 with non-ulcer dyspepsia). Gastric biopsy specimens were obtained and tested for H. pylori infection by rapid urease test and culture. PCR was performed on the isolated strains and biopsy specimens for detection of the cagA gene. Blood samples were collected and tested for CagA IgG by ELISA. H. pylori infection was detected among 72.8% of patients. The cagA gene and anti-CagA IgG were found in 63.4% and 61.8% of H. pylori-infected patients, respectively. They were significantly (p < 0.01) higher in patients with gastric cancer and peptic ulcer compared with those with non-ulcer dyspepsia. Detection of the CagA IgG was 91.6% sensitive, 89.6% specific, and 90.8% accurate compared with detection of the cagA gene. Its positive and negative predictive values were 93.8% and 86%, respectively. The study showed a significant association between the presence of the cagA gene and gastric cancer and peptic ulcer disease, and between anti-CagA IgG and the cagA gene in Saudi patients. However, a further larger study is required to confirm this finding.

    Chronic atrophic autoimmune gastritis (CAAG) is an organ-specific autoimmune disease characterized by an immune response, which is directed towards the parietal cells and intrinsic factor of the gastric body and fundus and leads to hypochlorhydria, hypergastrinemia and inadequate production of the intrinsic factor. As a result, the stomach’s secretion of essential substances, such as hydrochloric acid and intrinsic factor, is reduced, leading to digestive impairments. The most common is vitamin B12 deficiency, which results in a megaloblastic anemia and iron malabsorption, leading to iron deficiency anemia. However, in the last years the deficiency of several other vitamins and micronutrients, such as vitamin C, vitamin D, folic acid and calcium, has been increasingly described in patients with CAAG. In addition the occurrence of multiple vitamin deficiencies may lead to severe hematological, neurological and skeletal manifestations in CAAG patients and highlights the importance of an integrated evaluation of these patients. Nevertheless, the nutritional deficiencies in CAAG are largely understudied. We have investigated the frequency and associated features of nutritional deficiencies in CAAG in order to focus on any deficit that may be clinically significant, but relatively easy to correct. This descriptive review updates and summarizes the literature on different nutrient deficiencies in CAAG in order to optimize the treatment and the follow-up of patients affected with CAAG.

    2015-01-01

    Atrophic gastritis (AG) and intestinal metaplasia (IM) are the main precursor lesions of gastric cancer as the incidence of gastric cancer increases in the gastric mucosa involved with AG and IM. The prevalence of AG and IM vary depending on countries, even it represents diverse results in the same nation. Usually AG is antecedent of IM but the etiologies of AG and IM are not always the same. The sensitivity and specificity of diagnostic methods to detect AG and IM are different. Furthermore, the management strategy of AG and IM has not been established, yet. Helicobacter pylori infection has been proved as the most important cause of AG and IM. Thus the eradication of H. pylori is very important to prevent the progression to gastric cancer which is still placed in the high rank in morbidity and mortality among cancers. However, the reversibility of AG and IM by eradication of H. pylori which was assumed to be certain by meta-analysis is; however, controversial now. Therefore, the understanding and early diagnosis of AG and IM are very important, especially, in high incidence area of gastric cancer such as Republic of Korea. PMID:25853101

    Chronic atrophic gastritis (CAG) is a common gastrointestinal disease which has been considered as precancerous lesions of gastric carcinoma. Previously, electro-acupuncture stimulation has been shown to be effective in ameliorating symptoms of CAG. However the underlying mechanism of this beneficial treatment is yet to be established. In the present study, an integrated histopathological examination along with molecular biological assay, as well as (1)H NMR analysis of multiple biological samples (urine, serum, stomach, cortex and medulla) were employed to systematically assess the pathology of CAG and therapeutic effect of electro-acupuncture stimulation at Sibai (ST 2), Liangmen (ST 21), and Zusanli (ST 36) acupoints located in the stomach meridian using a rat model of CAG. The current results showed that CAG caused comprehensive metabolic alterations including the TCA cycle, glycolysis, membrane metabolism and catabolism, gut microbiota-related metabolism. On the other hand, electro-acupuncture treatment was found able to normalize a number of CAG-induced metabolomics changes by alleviating membrane catabolism, restoring function of neurotransmitter in brain and partially reverse the CAG-induced perturbation in gut microbiota metabolism. These findings provided new insights into the biochemistry of CAG and mechanism of the therapeutic effect of electro-acupuncture stimulations.

    Background and aims Atrophic gastritis (AG) results most often from Helicobacter pylori (H. pylori) infection. AG is the most important single risk condition for gastric cancer that often leads to an acid-free or hypochlorhydric stomach. In the present paper, we suggest a rationale for noninvasive screening of AG with stomach-specific biomarkers. Methods The paper summarizes a set of data on application of the biomarkers and describes how the test results could be interpreted in practice. Results In AG of the gastric corpus and fundus, the plasma levels of pepsinogen I and/or the pepsinogen I/pepsinogen II ratio are always low. The fasting level of gastrin-17 is high in AG limited to the corpus and fundus, but low or non-elevated if the AG occurs in both antrum and corpus. A low fasting level of G-17 is a sign of antral AG or indicates high intragastric acidity. Differentiation between antral AG and high intragastric acidity can be done by assaying the plasma G-17 before and after protein stimulation, or before and after administration of the proton pump inhibitors (PPI). Amidated G-17 will rise if the antral mucosa is normal in structure. H. pylori antibodies are a reliable indicator of helicobacter infection, even in patients with AG and hypochlorhydria. Conclusions Stomach-specific biomarkers provide information about the stomach health and about the function of stomach mucosa and are a noninvasive tool for diagnosis and screening of AG and acid-free stomach.

    A meta-analysis was performed to assess the diagnostic value of gastrin-17 (G-17) for the early detection of chronic atrophic gastritis (CAG).An extensive literature search was performed, with the aim of selecting publications that reported the accuracy of G-17 in predicting CAG, in the following databases: PubMed, Science Direct, Web of Science, Chinese Biological Medicine, Chinese National Knowledge Infrastructure, Wanfang, and VIP. To assess the diagnostic value of G-17, the following statistics were estimated and described: sensitivity, specificity, diagnostic odds ratios (DOR), summary receiver operating characteristic curves, area under the curve (AUC), and 95% confidence intervals (CIs).Thirteen studies that met the inclusion criteria were included in this meta-analysis, comprising 894 patients and 1950 controls. The pooled sensitivity and specificity of these studies were 0.48 (95% CI: 0.45-0.51) and 0.79 (95% CI: 0.77-0.81), respectively. The DOR was 5.93 (95% CI: 2.93-11.99), and the AUC was 0.82.G-17 may have potential diagnostic value because it has good specificity and a moderate DOR and AUC for CAG. However, more studies are needed to improve the sensitivity of this diagnostic tool in the future.

    Forty-three patients with cirrhosis and ascites, 21 with normal renal function, 10 with a progressive functional renal failure (FRF), and 12 with a steady FRF, were investigated for the presence of endotoxaemia by the Limulus lysate test. Endotoxaemia was found in nine patients with FRF and in none of the 21 with normal renal function (P less than 0-01). A positive Limulus test was almost exclusively associated with a progressive FRF (eight of 10 patients) and all but one of them died. Renal function improved as endotoxaemia disappeared in the survivor. Endotoxaemia was also associated with haemorrhage due to acute erosions of the gastric mucosa, being present in six of the seven patients who had this complication. Intravascular coagulation was not found in any patient. The Limulus test was positive in the ascitic fluid in 18 of 21 patients tested, although only two of them had peritonitis. These results suggest that endotoxaemia may play a critical role in the development of progressive renal failure and haemorrhagic gastritis in cirrhosis, and emphasise the potential risk of procedures involving reinfusion of ascitic fluid.

    Background. There are several diagnostic methods for Helicobacter pylori (H. pylori) infection. A cost-effective analysis is needed to decide on the optimal diagnostic method. The aim of this study was to determine a cost-effective diagnostic method in patients with atrophic gastritis (AG). Methods. A decision-analysis model including seven diagnostic methods was constructed for patients with AG diagnosed by esophagogastroduodenoscopy. Expected values of cost and effectiveness were calculated for each test. Results. If the prevalence of H. pylori in the patients with AG is 85% and CAM-resistant H. pylori is 30%, histology, stool H. pylori antigen (SHPAg), bacterial culture (BC), and urine H. pylori antibody (UHPAb) were dominated by serum H. pylori IgG antibody (SHPAb), rapid urease test (RUT), and urea breath test (UBT). Among three undominated methods, the incremental cost-effective ratios (ICER) of RUT versus SHPAb and UBT versus RUT were $214 and $1914, respectively. If the prevalence of CAM-sensitive H. pylori was less than 55%, BC was not dominated, but its H. pylori eradication success rate was 0.86. Conclusions. RUT was the most cost-effective at the current prevalence of CAM-resistant H. pylori. BC could not be selected due to its poor effectiveness even if CAM-resistant H. pylori was more than 45%.

    Chronic atrophic gastritis (CAG) is a common gastrointestinal disease which has been considered as precancerous lesions of gastric carcinoma. Previously, electro-acupuncture stimulation has been shown to be effective in ameliorating symptoms of CAG. However the underlying mechanism of this beneficial treatment is yet to be established. In the present study, an integrated histopathological examination along with molecular biological assay, as well as 1H NMR analysis of multiple biological samples (urine, serum, stomach, cortex and medulla) were employed to systematically assess the pathology of CAG and therapeutic effect of electro-acupuncture stimulation at Sibai (ST 2), Liangmen (ST 21), and Zusanli (ST 36) acupoints located in the stomach meridian using a rat model of CAG.

    Objectives: In order to test the hypothesis that H. pylori infections in the gastric antrum increase pepsinogen I release, fasting serum pepsinogen I concentrations were compared in peptic ulcer patients with and without H. pylori infection. A randomized prospective study was performed to determine whether the increased serum pepsinogen I concentrations associated with H. pylori infection respond to treatment that eradicates H. pylori. Methods: Fasting serum pepsinogen I concentrations were measured by RIA in 736 patients with endoscopically and histologically confirmed benign peptic ulcer with and without H. pylori infection. Out of 511 patients with H. pylori infection, 110 patients (group 1) were randomly selected and were treated with metronidazole and tripotassium dicitrato bismuthate combined with ranitidine and antacid, and 97 patients (group 2) were treated only with ranitidine and antacid. The third group, 54 patients free of H. pylori infection, was designed to evaluate the influence of H2-receptor antagonist and antacid on the change of pepsinogen I. Fasting pepsinogen I concentration and H. pylori status were compared before and after the treatment. Results: Patients infected by H. pylori (gastric ulcer 208, duodenal ulcer 303; total 511) had significantly higher fasting serum pepsinogen I concentrations than H. pylori negative patients (gastric ulcer 110, duodenal ulcer 115: total 225). Mean pepsinogen I level of the former was 124.3±46.9 and that of the latter was 77.9±25.8 ng/ml. (p<0.0001) The difference in serum pepsinogen I concentrations according to the location of ulcer crater was significant only in non-infected subjects e.g., mean pepsinogen I level H. pylori-negative gastric ulcer was significantly lower than that of H. pylori-negative duodenal ulcer patients. H. pylori was eradicated in all the patients who had received antibacterial therapy for 4 weeks and serum pepsinogen I concentrations were significantly decreased from 129.8+43.0 to

    Purpose A duodenal bypass after a Roux-en-Y gastric bypass operation for obesity can ameliorate the development of diabetes mellitus (DM). We attempted to determine the subsequent risk of developing DM after subtotal gastrectomy with Billroth II anastomosis (SGBIIA) for peptic ulcer disease (PUD). Methods We identified 662 patients undergoing SGBIIA for PUD between 2000 and 2011 from the Longitudinal Health Insurance Database as the study cohort, and we randomly selected 2647 controls from the peptic ulcer population not undergoing SGBIIA and were frequency-matched by age, sex, and index year for the control cohort. All patient cases in both cohorts were followed until the end of 2011 to measure the incidence of DM. We analyzed DM risk by using a Cox proportional hazards regression model. Results The patients who underwent SGBIIA demonstrated a lower cumulative incidence of DM compared with the control cohort (log-rank test, P < .001 and 6.73 vs 12.6 per 1000 person-y). The difference in the DM risk between patients with and without SGBIIA increased gradually with the follow-up duration. Age and sex did not affect the subsequent risk of developing DM, according to the multivariable Cox regression model. Nevertheless, the SGBIIA cohort exhibited a lower DM risk after we adjusted for the comorbidities of hypertension, hyperlipidemia, and coronary artery disease (adjusted hazard ratio (aHR): 0.56, 95% confidence interval (CI): 0.40–0.78). The incidence rate ratio (IRR) of DM in the SGBIIA cohort was lower than that in the control cohort for all age groups (age ≤ 49 y, IRR: 0.40, 95% CI: 0.16–0.99; age 50–64 y, IRR: 0.54, 95% CI: 0.31–0.96; age ≧ 65 y, IRR: 0.57, 95% CI: 0.36–0.91). Moreover, the IRR of DM was significantly lower in the SGBIIA cohort with comorbidities (IRR: 0.50, 95% CI: 0.31–0.78) compared with those without a comorbidity (IRR: 0.65, 95% CI: 0.40–1.04). Conclusion The findings of this population-based cohort study revealed that

    BACKGROUND The appropriate dose of proton pump inhibitors for treatment of patients with upper (GI) bleeding remains controversial. This study compares high-dose versus low-dose intravenous proton pump inhibitor (PPI) infusion for prevention of GI bleeding complications. METHODS A total of 166 patients with bleeding peptic ulcers underwent therapeutic endoscopy using concomitant therapy by argon plasma coagulation (APC) and diluted epinephrine injection. Patients were randomly divided into two groups: high-dose pantoprazole (80 mg bolus, 8 mg per hour) and low-dose pantoprazole (40 mg bolus, 4 mg per hour) infused for three days. Initial outcomes were rebleeding, need for surgery, hemoglobin drop more than two units, and hospitalization for more than five days. Secondary outcome included mortality rate. RESULTS Overall, 166 patients (83 patients per group) enrolled in the study. The average age of patients in the high-dose group was 59.5±15.6 years and 52.3±13.3 years in the low-dose group (p=0.58). Males comprised 69.7% of patients. In the high-dose group, the mean number of units of transfused blood was 3.3±1.71 and in the low-dose group, it was 2.82±1.73 (p=0.50). There were 36 (43.37%) patients in the high-dose group and 40 (48.19%) in the low-dose group who were hospitalized for more than 5 days (p=0.53). Rebleeding was observed in 27 (32.53%) patients in the high-dose group and in 21 (25.30%) in the low-dose group (p=0.30). There were no significant differences observed in drop in hemoglobin of more than two units (p=0.15), mortality (p=0.99) and surgery (p=0.75) between the two groups. CONCLUSION For controlling peptic ulcer bleeding, there is no difference between high dose and low dose pantoprazole infusion. PMID:25093061

    MiR-27a rs895819 is a loop-stem structure single nucleotide polymorphism affecting mature miR-27a function. In this study, we performed a comprehensive analysis about the association of rs895819 with gastric cancer risk and prognosis, atrophic gastritis risk, as well as the interactions with environmental factors. A total of 939 gastric cancer patients, 1,067 atrophic gastritis patients and 1,166 healthy controls were screened by direct sequencing and MALDI-TOF-MS. The association of rs895819 with clinical pathological parameters and prognostic survival in 357 gastric cancer patients was also been analyzed. The rs895819 variant genotype increased the risk for atrophic gastritis (1.58-fold) and gastric cancer (1.24-fold). While in stratified analysis, the risk effect was demonstrated more significantly in the female, age >60y, Helicobacter pylori (H. pylori) negative and non-drinker subgroups. Rs895819 and H. pylori showed an interaction effect for atrophic gastritis risk. In the survival analysis, the rs895819 AG heterozygosis was associated with better survival than the AA wild-type in the TNM stage I–II subgroup. In vitro study by overexpressing miR-27a, cells carrying polymorphic-type G allele expressed lower miR-27a than wild-type A allele. In conclusion, miR-27a rs895819 is implicated as a biomarker for gastric cancer and atrophic gastritis risk, and interacts with H. pylori in gastric carcinogenesis. PMID:28150722

    Background: Over the last years, our knowledge on pathogenesis of gastric MALT lymphoma has greatly improved, but its morphological diagnosis is still hampered by overlapping histological features with advanced chronic gastritis. MicroRNAs are deregulated in lymphomas, but their role and usefulness in gastric MALT lymphoma has not been extensively investigated. Materials and Methods: We analyzed the expression of 384 miRNAs using TaqMan microRNA assay in a training series of 10 gastric MALT lymphomas, 3 chronic gastritis and 2 reactive lymph nodes. Then, significantly deregulated miRNAs were individually assessed by real-time PCR in a validation series of 16 gastric MALT lymphomas and 12 chronic gastritis. Results: Gastric MALT lymphoma is characterized by a specific miRNA expression profile. Among the differentially expressed miRNAs, a significant overexpression of miR-142-3p and miR-155 and down-regulation of miR-203 was observed in gastric MALT lymphoma when compared to chronic gastritis. Conclusion: miR-142-3p, miR-155 and miR-203 expression levels might be helpful biomarkers for the differential diagnosis between gastric MALT lymphomas and chronic gastritis. *These Authors contributed equally to this study.

    Background and aims Gastric mucosa associated lymphoid tissue lymphoma is a well defined B cell lymphoma yet often impossible to distinguish from severe chronic gastritis on morphological grounds alone. Therefore, it was suggested to use the clonality of the immunoglobulin (Ig) heavy chain (H) genes, as detected by polymerase chain reaction (PCR), as a decisive criterion. However, there is controversy as to whether B cell clonality also exists in chronic gastritis, hence rendering this approach futile at present. Methods An expert panel re‐examined the histology and immunohistochemistry of a total of 97 cases of gastric biopsies, including clearcut marginal zone lymphoma, chronic gastritis, and ambiguous cases, applying the Wotherspoon criteria on the basis of haematoxylin‐eosin and CD20 immunostainings. In addition, a new and advanced PCR system for detection of clonal IgH gene rearrangements was independently applied in two institutions in each case. Results The overall IgH clonality assessments of both institutions were in total agreement. Overt lymphoma (Wotherspoon score 5) was clonal in 24/26 cases. Chronic gastritis (Wotherspoon scores 1 and 2) was not clonal in 52/53 cases; the clonal case being Wotherspoon score 2. Of 18 cases with ambiguous histology (Wotherspoon scores 3 and 4) four were clonal. Conclusions Using advanced PCR technology, clonal gastritis is extremely rare, if it exists at all. Thus B cell clonality in Wotherspoon 3 and 4 cases is regarded as suitable for definitively diagnosing gastric marginal zone lymphoma. PMID:16423889

    Previous studies have reported that patients with bipolar disorders (BDs) exhibit increased physical comorbidity and psychological distress. Studies have shown that schizophrenia and anxiety increase the risk of peptic ulcer diseases (PUDs). Therefore, we conducted this study to determine the association between these 2 diseases and examine the possible risk factors. We used patients diagnosed with BDs from the Taiwan National Health Insurance Research Database. A comparison cohort comprising patients without BDs was frequency matched by age, sex, and comorbidities, and the occurrence of PUDs was evaluated in both the cohorts. The BD and non-BD cohort consisted of 21,060 patients with BDs and 84,240 frequency-matched patients without BDs, respectively. The incidence of PUDs (hazard ratio, 1.51; 95% confidence interval, 1.43-1.59; P < 0.001) was higher among the patients with BDs than the control patients. Cox models showed that irrespective of comorbidities, BDs were an independent risk factor for PUDs. Patients with BDs exhibit a substantially higher risk for developing PUDs. According to our data, we suggest that, following a diagnosis of BD, practitioners could notice the occurrence of PUD and associated prevention. Further prospective clinical studies investigating the relationship between BDs and PUDs are warranted.

    More than a million people die every year due to gastric cancer and peptic ulcer. Helicobacter pylori infection in stomach is the most important reason for these diseases. Interestingly, only 10–20% of the H. pylori infected individuals suffer from these gastric diseases and rest of the infected individuals remain asymptomatic. The genotypes of H. pylori, host genetic background, lifestyle including smoking and diet may determine clinical outcomes. People from different geographical regions have different food habits, which also include several unique fermented products of plant and animal origins. When consumed raw, the fermented foods bring in fresh inocula of microbes to gastrointestinal tract and several strains of these microbes, like Lactobacillus and Saccharomyces are known probiotics. In vitro and in vivo experiments as well as clinical trials suggest that several probiotics have anti-H. pylori effects. Here we discuss the possibility of using natural probiotics present in traditional fermented food and beverages to obtain protection against H. pylori induced gastric diseases. PMID:27504109

    AIM: To assess the risk factors and the efficacy of medications of patients with gastric and duodenal ulcers among Chinese patients in Taiwan. METHODS: Patients with peptic ulcers, diagnosed by upper endoscopy, were retrospectively collected between January 2008 and December 2008. The differences were compared. RESULTS: Among all 448 cases, 254 (56.6%) and 194 (43.4%) patients had gastric ulcers and duodenal ulcers respectively. Patients with gastric ulcers were younger than those with duodenal ulcers. Although more men existed, there was a female predominance in middle-aged cases. Patients with duodenal ulcers had a higher rate of Helicobacter pylori (H. pylori) infection (62.4% vs 43.3%, P = 0.001), and those with gastric ulcers owned a significantly higher amount of aspirin and nonsteroidal anti-inflammatory drug (NSAID) use (7.5% vs 1.5%, 6.7% vs 2.1%, P = 0.001). Tobacco smoking and alcohol drinking had no different impact between these two groups. Proton-pump inhibitors and H2-receptor antagonists (H2RA) were effective, but significantly less so in cases with duodenal ulcers receiving H2RAs, or in those with H. pylori infection and a history of NSAID use. CONCLUSION: Patients with gastric ulcers had lower H. pylori infection but more aspirin or NSAID use. Antisecretory therapy was ineffective in gastric ulcers underwent H2RA treatment, and cases combined H. pylori infection and NSAID use. PMID:20419840

    Background/Aims The purpose of this study is to investigate the recurrence rate of peptic ulcer disease (PUD) over a long follow-up period with PUD patients without Helicobacter pylori. Methods We retrospectively reviewed patients diagnosed with PUD on endoscopy and divided them into two groups: a H. pylori-negative group (HP-negative group), and a group of patients with untreated H. pylori (HP noneradicated group). We compared the recurrence rates of PUD in these two groups and analyzed the factors that affected ulcer recurrence. Results Total of nine hospitals in Korea participated, and a total of 1,761 patients were retrospectively reviewed. The HP-negative group included 553 patients, and the HP noneradicated group included 372 patients. The 5-year cumulative probabilities of PUD recurrence were 36.4% in the HP-negative group and 43.8% in the HP noneradicated group (p=0.113). The factors that were found to affect recurrence in the HP-negative group were elder, male, and comorbid chronic kidney disease. Conclusions The 5-year cumulative probability of PUD recurrence without H. pylori infection after a long-term follow-up was 36.4% and the factors that affected recurrence were elder, male, and comorbid chronic kidney disease.

    Background/Aims Helicobacter pylori is a major risk factor for atrophic gastritis (AG) and gastric cancer. The correlation between H. pylori, AG and colorectal neoplasm (CRN) has only been examined in a limited number of studies, and findings have been inconclusive. We aimed to investigate the association between H. pylori infection status, AG and advanced CRN. Methods This cross-sectional study investigated the relationship between the presence of serum anti-H. pylori IgG antibodies, AG, and advanced CRN in 6,351 consecutive asymptomatic subjects who underwent a screening colonoscopy. Results A total of 316 participants (5.0%) had advanced CRN. H. pylori seropositivity was 61.3%. In a univariate analysis, the presence of H. pylori infection was associated with advanced CRN (odds ratio [OR], 1.49; 95% confidence interval [CI], 1.17 to 1.91; p=0.001). H. pylori infection was associated with an increased risk of advanced CRN after adjusting for clinically relevant confounders (OR, 1.34; 95% CI, 1.04 to 1.72; p=0.023). H. pylori-related AG was significantly associated with the risk of advanced CRN (OR, 1.40; 95% CI, 1.03 to 1.91; p=0.030), whereas H. pylori infection without AG was not. Conclusions H. pylori infection increased the risk of advanced CRN, especially when it was combined with AG. Strict colonoscopy screening and surveillance may be warranted in those with H. pylori-positive AG. PMID:27458180

    Background It has been suggested that GastroPanel might be a useful tool for the diagnosis of chronic atrophic gastritis (CAG) measuring four biomarkers in blood: basal gastrin-17 (G17), pepsinogen I and II (PGI and PGII), and Helicobacter pylori antibodies. Aim To determine the accuracy of GastroPanel for the diagnosis of CAG. Methods This was a prospective, blinded, multicenter study that included dyspeptic patients. G17, PGI, and PGII were determined by enzyme immunoassays. Three antrum and two corpus biopsies were obtained for standard histological analysis and rapid urease test. Biopsies were analyzed by a single blinded expert pathologist. Results Ninety-one patients were included (77% women, mean age 44 years, 51% H. pylori positive, 17% with CAG). G17 was reduced in patients with antrum CAG (5.4 vs. 13.4 pmol/l; P<0.01) and increased in patients with corpus CAG (11 vs. 24 pmol/l; P<0.05), but its accuracy was only acceptable in the case of corpus localization [area under the receiver operating characteristic curve (AUC), 74%]; PGII difference was almost statistically significant only when testing for corpus atrophy (33 vs. 21 μg/l; P=0.05; AUC=72%). The PGI and PGI/PGII ratio showed no significant differences (AUCs were all unacceptably low). Helicobacter pylori antibody levels were higher in H. pylori-infected patients (251 vs. 109 EIU, P=0.01; AUC=70). The accuracy of GastroPanel for the diagnosis of CAG was as follows: sensitivity 50%; specificity 80%; positive 25% and negative 92% predictive values; and positive 2.4 and negative 0.6 likelihood ratios. Conclusion GastroPanel is not accurate enough for the diagnosis of CAG; thus, its systematic use in clinical practice cannot be recommended. PMID:25014624

    Exercise-induced gastritis and gastric ulcers are common in humans and horses, and recently have been described in racing sled dogs. The cause of exercise-induced gastric disease is not completely understood in any species, but pharmacologic suppression of acid secretion is an effective treatment in humans and horses. Thus, we tested the hypothesis that omeprazole, a proton-pump inhibitor shown to reduce gastric acid secretion in dogs, would reduce the severity of exercise-induced gastric disease. Three teams of 16 dogs each competing in the 2002 Iditarod Sled Dog Race were recruited for participation. Within each team, dogs were randomly assigned to either treatment (20 mg omeprazole PO q24h) or placebo. Treatments were administered until either completion of the race or withdrawal of an individual dog from competition. Gastric endoscopy was performed in all dogs 24 hours after completion or withdrawal, and the gastric mucosa was scored by using a subjective severity score (0 = normal, 3 = numerous bleeding ulcers). Treatment with omeprazole significantly reduced mean gastricseverity score compared to placebo (omeprazole: 0.65 +/- 0.17, placebo: 1.09 +/- 0.18; P = .028), but also was associated with increased frequency of diarrhea during the race (omeprazole 54%, placebo 21%; P = .017). Examination of our data suggests that omeprazole may be an effective treatment for exercise-induced gastric disease in racing sled dogs. However, further investigation regarding the cause and clinical relevance of diarrhea associated with omeprazole treatment must be conducted before omeprazole can be recommended for routine prophylactic treatment in these athletes.

    Symptoms of severe nausea, vomiting, abdominal pain, and frequent bezoars, as well as objective gastric retention, can occur following Roux-Y biliary diversion for alkaline reflux gastritis. Medical therapy and prokinetic drugs have proven ineffective. This review evaluates 37 patients who underwent further gastric resection from 1979 to 1987 to improve gastric emptying and resolve symptoms. Fifteen patients underwent perioperative radionuclide solid-food gastric emptying studies. Seventy-three per cent (27 of 37 patients) of the patients who underwent further gastric resection (70% to 95%) had a satisfactory postoperative response. Twenty patients were graded Visick 1 or 2 and 7 Visick-3 patients, although much improved, still had some symptoms of gastroparesis. Twenty-seven per cent (10 of 37 patients) failed to improve and underwent completion total gastrectomy. Overall, 70% of this group had almost complete resolution of their symptoms. Three of 10 patients were considered ''failures'' due to postprandial pain in 1 and early vasomotor dumping in 2. Of the 10 patients who failed initial revisional surgery, 7 underwent a 70% to 80% subtotal gastric resection (STG) and 3 patients underwent 85% to 95% extensive resection (EXT.G.). Of the 15 patients who underwent perioperative radionuclide evaluation, a mean two-hour gastric retention of 61.4% +/- 4% (SEM) decreased to 25% +/- 4% following further gastric resection. Eight patients were in the STG group and seven patients were in the EXT.G group. Following STG, mean two-hour gastric retention of 58.2% +/- 3.5% decreased to 38% +/- 3% (p less than 0.05). In seven patients who underwent EXT.G, mean two-hour retention of 65% +/- 4% decreased to 10% +/- 2.5% (p less than 0.005). EXT.G resulted in normal gastric emptying and few late failures.

    Capsule Endoscopy (CE) was introduced in 2000 and has since become an established diagnostic procedure for the small bowel, colon and esophagus. For the CE examination the patient swallows the capsule, which then travels through the gastrointestinal tract under the influence of the peristaltic movements. CE is not indicated for stomach examination, as the capsule movements can not be controlled from the outside and the entire surface of the stomach can not be reliably covered. Magnetically-guided capsule endoscopy (MGCE) was introduced in 2010. For the MGCE procedure the stomach is filled with water and the capsule is navigated from the outside using an external magnetic field. During the examination the operator can control the motion of the capsule in order to obtain a sufficient number of stomach-surface images with diagnostic value. The quality of the examination depends on the skill of the operator and his ability to detect aspects of interest in real time. We present a novel computer-assisted diagnostic-procedure (CADP) algorithm for indicating gastritis pathologies in the stomach during the examination. Our algorithm is based on pre-processing methods and feature vectors that are suitably chosen for the challenges of the MGCE imaging (suspended particles, bubbles, lighting). An image is classified using an ada-boost trained classifier. For the classifier training, a number of possible features were investigated. Statistical evaluation was conducted to identify relevant features with discriminative potential. The proposed algorithm was tested on 12 video sequences stemming from 6 volunteers. A mean detection rate of 91.17% was achieved during leave-one out cross-validation.

    Chronic atrophic gastritis (CAG) is an important precursor lesion of intestinal gastric cancer. As it is typically asymptomatic, epidemiological data on the incidence of CAG are sparse. We aimed to provide an overview of published data on CAG incidence (overall and according to risk factors) from follow-up studies. Articles with information on incidence of CAG published in English until 26th of July 2009 were identified through a systematic MEDLINE and EMBASE search. Data extracted include study characteristics and key findings regarding the incidence of CAG. A meta-analysis was performed on the association between Helicobacter pylori infection and CAG incidence. Overall, data on CAG incidence were available from 14 studies, in 7 studies incidence could be estimated according to H. pylori infection. Most studies were conducted in symptomatic or high risk populations and the maximum number of incident cases was 284. Incidence estimates ranged from 0 to 11% per year and were consistently below 1% in patients not infected with H. pylori. The highest incidence was observed in a special study conducted on ulcer patients treated by proximal gastric vagotomy. Rate ratios for the association between H. pylori infection and CAG incidence ranged from 2.4 to 7.6 with a summary estimate of 5.0 (95% confidence interval: 3.1-8.3). Incidence of CAG is very low in the absence of H. pylori infection. There is a need for more population-based studies to provide comparable estimates of incidence and the impact of risk factors in the development of CAG.

    Ulcer is a common gastrointestinal disorder which is seen among many people. It is basically an inflamed break in the skin or the mucus membrane lining the alimentary tract. Ulceration occurs when there is a disturbance of the normal equilibrium caused by either enhanced aggression or diminished mucosal resistance. It may be due to the regular usage of drugs, irregular food habits, stress, and so forth. Peptic ulcers are a broad term that includes ulcers of digestive tract in the stomach or the duodenum. The formation of peptic ulcers depends on the presence of acid and peptic activity in gastric juice plus a breakdown in mucosal defenses. A number of synthetic drugs are available to treat ulcers. But these drugs are expensive and are likely to produce more side effects when compared to herbal medicines. The literature revealed that many medicinal plants and polyherbal formulations are used for the treatment of ulcer by various ayurvedic doctors and traditional medicinal practitioners. The ideal aims of treatment of peptic ulcer disease are to relieve pain, heal the ulcer, and delay ulcer recurrence. In this review attempts have been made to know about some medicinal plants which may be used in ayurvedic as well as modern science for the treatment or prevention of peptic ulcer. PMID:24971094

    Eighteen patients with diffuse varioliform gastritis were enrolled in a double-blind, placebo-controlled trial of sodium cromoglycate, 200 mg a day, and sodium cromoglycate, 400 mg a day, for 28 days. An additional six patients were treated with cimetidine 1 g daily for 28 days. The improvement in terms of patient's subjective assessment, endoscopic assessment, and immunohistochemical measurements of IgE cells in the mucosa was significantly greater in patients given sodium cromoglycate than that in those given cimetidine or placebo. The results provide evidence that type 1 hypersensitivity plays some part in the pathogenesis of varioliform gastritis. It is, therefore, important to differentiate this condition from other types of gastritis, as treatment with sodium cromoglycate appears to be affective. Images Fig. 1 Fig. 2 PMID:6804311

No significant difference in the distribution of the 10 studied regions was found between the cases and the controls. Nine strains did not harbor any of the selected regions: eight (30.8%) isolated from patients with gastritis only and one (5.9%) from a patient with gastric carcinoma. No association was found between the number of repeated sequences at the 3′ end of the cagA gene or the presence of tyrosine phosphorylation motifs and the clinical origin of the strains. The virB10 homolog gene was the sole gene studied to be significantly expressed more often in cancer strains than in gastritis strains (P = 0.03). PMID:11179371

    The study was intended to develop a new intra-gastric floating in situ microballoons system for controlled delivery of rabeprazole sodium and amoxicillin trihydrate for the treatment of peptic ulcer disease. Eudragit S-100 and hydroxypropyl methyl cellulose based low density microballoons systems were fabricated by employing varying concentrations of Eudragit S-100 and hydroxypropyl methyl cellulose, to which varying concentrations of drug was added, and formulated by stirring at various speed and time to optimize the process and formulation variable. The formulation variables like concentration and ratio of polymers significantly affected the in vitro drug release from the prepared floating device. The validation of the gastro-retentive potential of the prepared microballoons was carried out in rabbits by orally administration of microballoons formulation containing radio opaque material. The developed formulations showed improved buoyancy and lower ulcer index as compared to that seen with plain drugs. Ulcer protective efficacies were confirmed in ulcer-bearing mouse model. In conclusion, greater compatibility, higher gastro-retention and higher anti-ulcer activity of the presently fabricated formulations to improve potential of formulation for redefining ulcer treatment are presented here. These learning exposed a targeted and sustained drug delivery potential of prepared microballoons in gastric region for ulcer therapeutic intervention as corroborated by in vitro and in vivo findings and, thus, deserves further attention for improved ulcer treatment.

    In the present study, the gastroprotective mechanism of Xylocarpus granatum fruit and its active constituents gedunin and photogedunin was investigated. Chloroform fraction (Fr-CHCl(3)) of X. granatum fruit was evaluated against cold restraint (CRU), aspirin (AS), alcohol (AL) and pyloric ligation (PL) induced gastric ulcer models in rats and histamine (HA) induced duodenal ulcer model in guinea pigs. Potential anti-ulcer activity of Fr-CHCl(3) was observed against CRU (58.28%), AS (67.81%), AL (84.38%), PL (65.66%) and HA (61.93%) induced ulcer models. The standard drug omeprazole (10mg/kg, p.o.) showed 68.25% protection against CRU, 57.08% against AS and 69.42% against PL model and 70.79% against HA induced duodenal ulcer. Sucralfate, another standard drug (500 mg/kg, p.o.) showed 62.72% protection in AL induced ulcer model. Fr-CHCl(3) significantly reduced free acidity (51.42%), total acidity (30.76%) and upregulated mucin secretion by 58.37% respectively. Phytochemical investigations of Fr-CHCl(3) yielded gedunin (36%), photogedunin (2%). Further, Fr-CHCl(3) and its compounds gedunin and photogedunin significantly inhibited H(+) K(+)-ATPase activity in vitro with IC(50) of 89.37, 56.86 and 66.54 microg/ml respectively as compared to the IC(50) value of omeprazole (30.24 microg/ml) confirming their anti-secretory activity. Conclusively, Fr-CHCl(3) of Xylocarpus granatum was found to possess anti-ulcerogenic activity which might be due to its anti-secretory activity and subsequent strengthening of the defensive mechanism. This study is the first of its kind to show significant anti-secretory effect of gedunin and photogedunin. Therefore it could act as a potent therapeutic agent against peptic ulcer disease.

    The association of Helicobacter pylori eradication with the occurrence of renal dysfunction in patients with peptic ulcer diseases is still unclear. This study aimed to clarify the relevance of H. pylori eradication to the occurrence of chronic kidney diseases in patients with peptic ulcer diseases. Data that were available from 2000–2011 were extracted from the National Health Insurance Research Database in Taiwan, and all patients with peptic ulcer diseases (n = 208 196) were screened for eligibility. We divided randomly selected patients into an H. pylori eradication cohort (cohort A, n = 3593) and matched them by age and sex to a without H. pylori eradication cohort (cohort B, n = 3593). Subgroup analysis was further performed for H. pylori eradication within ≤ 90 days of the diagnosis date (early eradication, n = 2837) and within 91–365 days (non-early eradication, n = 756). Cox proportional hazards regression analysis was used to estimate the association of H. pylori eradication with the risk of developing chronic kidney diseases and mortality. We observed that there were more patients suffering from chronic kidney disease in cohort B than in the early eradication subgroup of cohort A (8.49% vs. 6.70%, respectively, p = 0.0075); the mortality rate was also higher in cohort B (4.76% vs. 3.70%, respectively, p = 0.0376). Old age, pulmonary disease, connective tissue disorders, and diabetes were risk factors for chronic kidney diseases but early H. pylori eradication was a protective factor against chronic kidney diseases (hazard ratio: 0.68, 95% confidence interval: 0.52–0.88, p = 0.0030), and death (hazard ratio: 0.69, 95% confidence interval: 0.49–0.96, p = 0.0297). In conclusion, our findings have important implications suggesting that early H. pylori eradication is mandatory since it is associated with a protective role against the occurrence of chronic kidney diseases.

    Background: A randomized prospective study on the response of fasting serum gastrin concentrations in peptic ulcer patients was performed in order to test the hypothesis that H. pylori infection in the gastric antrum increases gastrin release, and to examine whether the high fasting serum gastrin concentrations respond to treatment that eradicates H. pylori. Methods: One hundred and twenty-seven patients with gastric or duodenal ulcer were included in this study. Patients were divided into three groups on the basis of antral H. pylori status and therapeutic modalities. The first group, 58 patients infected by H. pylori, was treated with metronidazole and tripotassium dicitrato bismuthate combined with ranitidine and mylanta. The second group, 40 patients also infected by H. Pylori, was treated with ranitidine and mylanta. The third group, 29 patients, free of H. pylori infection, was designed to evaluate the influence of H2-receptor antagonist on the change of gastrin. When ulcers were completely healed, changes of gastrin concentrations and H. pylori status were re-examined. Results: H. pylori was eradicated in all patients who have received antibacterial therapy in 4 weeks, and serum gastrin concentrations were significantly decreased after eradication of the organism both in gastric and in duodenal ulcer diseases. (Gastric ulcer: 129.3±47.0 pg/ml before and 63.7±21.6 pg/ml after treatment. Duodenal ulcer: 108.3±35.0 pg/ml and 66.5±21.9 pg/ml, respectively. Total: 112.7±38.2 pg/ml vs 66.0±21.6 pg/ml) (p<0.01). In contrast, H. pylori-positive patients who have not received antibacterial therapy were still infected at the completion of the study, and serum gastrin concentrations increased even though the difference was not significant.

    The long-term use of proton pump inhibitors (PPIs) exacerbates corpus atrophic gastritis in patients with Helicobacter pylori (H. pylori) infection. To identify a potential mechanism for this change, we discuss interactions between pH, bile acids, and H. pylori. Duodenogastric reflux, which includes bile, occurs in healthy individuals, and bile reflux is increased in patients with gastroesophageal reflux disease (GERD). Diluted human plasma and bile acids have been found to be significant chemoattractants and chemorepellents, respectively, for the bacillus H. pylori. Although only taurine conjugates, with a pKa of 1.8-1.9, are soluble in an acidic environment, glycine conjugates, with a pKa of 4.3-5.2, as well as taurine-conjugated bile acids are soluble in the presence of PPI therapy. Thus, the soluble bile acid concentrations in the gastric contents of patients with GERD after continuous PPI therapy are considerably higher than that in those with intact acid production. In the distal stomach, the high concentration of soluble bile acids is likely to act as a bactericide or chemorepellent for H. pylori. In contrast, the mucous layer in the proximal stomach has an optimal bile concentration that forms chemotactic gradients with plasma components required to direct H. pylori to the epithelial surface. H. pylori may then colonize in the stomach body rather than in the pyloric antrum, which may explain the occurrence of corpus-predominant gastritis after PPI therapy in H. pylori-positive patients with GERD.

    The purpose of the study was to evaluate medical, social, and economic effectiveness of treatment of day-case patients with peptic ulcer (PU). The subjects of the study were 60 day-case patients with duodenal ulcer aged 18 to 60, who underwent clinical and instrumental examination including esophagogastroduodenoscopy with biopsy and Helicobacter pylori (HP) detection. The patients received 7-day eradication therapy, which included omeprazol in a dose of 20 mg twice a day, clarithromycin--500 mg twice a day, and metronidazole--500 mg twice a day. There was a control group, which included 60 inpatients treated in Gastroenterology Division of the hospital. The use of the three-component medication in the day-case patients and the inpatients led to disappearance of pain syndrome 7.4 +/- 0.3 and 8.6 +/- 0.2 days after the beginning of the treatment, respectively; dyspepsia disappeared in the day-case patients and the inpatients 7.6 +/- 0.2 and 8.8 +/- 0.3 days after the beginning of the treatment, respectively. HP eradication was effective in 86.7% of the day-case patients, and in 88.3% of the inpatients. The course of the disease was recurrence-free during two years in 80% of the day-case patients, and in 76.4% of the inpatients; the cost of the treatment was 2.1 times higher in the group of inpatients. The results show that high effectiveness of the three-component medication, judging by the results of HP eradication, terms of disappearance of pain syndrome and ulcer healing, allows recommending this regimen for wide clinical application in day-case patients with PU.

    The prevalence of peptic ulcer disease (PUD) and the frequency of operation have been decreasing for decades. Immigration of patients harboring Helicobacter pylori may reverse these longstanding declines. The experience with a large public hospital population in an area of high immigration may portend future national trends. A 10-year retrospective study analyzed the changing demographics of PUD and the frequency and nature of surgical intervention. A total of 2,182 patients were diagnosed with PUD, 1,173 in the early period (1995-1999) and 1,009 in the recent period (2000-2004). The proportion of Hispanic patients increased from 39.3 per cent to 47.5 per cent (P = 0.017). The ratio of male to female patients decreased from 1.7:1 to 1.3:1 (P = 0.003). The PUD operation rate decreased from 6.7 per cent to 3.8 per cent (P = 0.004). Among operated patients, the frequency of H. pylori testing increased from 41.8 per cent to 81.6 per cent (P = 0.039). Acute perforation and bleeding necessitated the vast majority (87.2%) of operations. The use of acid-reducing operations declined from 50.6 per cent to 31.6 per cent in favor of nonacid-reducing "damage control" procedures. Contrary to historic trends, in the predominately immigrant public hospital patient population studied, 1) the incidence of PUD is decreasing only modestly, 2) male predominance is disappearing, 3) gastric ulcer (GU) is more prevalent than duodenal ulcer (DU), but DU requires operation more frequently than GU, and 4) there is a marked decrease in use of acid-reducing operations reflecting a new "damage control" surgical approach to acute PUD complications in the H. pylori era.

    Health care workers (HCWs) in Taiwan have heavy, stressful workloads, are on-call, and have rotating nightshifts, all of which might contribute to peptic ulcer disease (PUD). We wanted to evaluate the PUD risk in HCWs, which is not clear. Using Taiwan's National Health Insurance Research Database, we identified 50,226 physicians, 122,357 nurses, 20,677 pharmacists, and 25,059 other HCWs (dieticians, technicians, rehabilitation therapists, and social workers) as the study cohort, and randomly selected an identical number of non-HCW patients (i.e., general population) as the comparison cohort. Conditional logistical regression analysis was used to compare the PUD risk between them. Subgroup analysis for physician specialties was also done. Nurses and other HCWs had a significantly higher PUD risk than did the general population (odds ratio [OR]: 1.477; 95% confidence interval [CI]: 1.433-1.521 and OR: 1.328; 95% CI: 1.245-1.418, respectively); pharmacists had a lower risk (OR: 0.884; 95% CI: 0.828-0.945); physicians had a nonsignificantly different risk (OR: 1.029; 95% CI: 0.987-1.072). In the physician specialty subgroup analysis, internal medicine, surgery, Ob/Gyn, and family medicine specialists had a higher PUD risk than other physicians (OR: 1.579; 95% CI: 1.441-1.731, OR: 1.734; 95% CI: 1.565-1.922, OR: 1.336; 95% CI: 1.151-1.550, and OR: 1.615; 95% CI: 1.425-1.831, respectively). In contrast, emergency physicians had a lower risk (OR: 0.544; 95% CI: 0.359-0.822). Heavy workloads, long working hours, workplace stress, rotating nightshifts, and coping skills may explain our epidemiological findings of higher risks for PUD in some HCWs, which might help us improve our health policies for HCWs.

    The Japanese Society of Gastroenterology (JSGE) revised the evidence-based clinical practice guidelines for peptic ulcer disease in 2014 and has created an English version. The revised guidelines consist of seven items: bleeding gastric and duodenal ulcers, Helicobacter pylori (H. pylori) eradication therapy, non-eradication therapy, drug-induced ulcer, non-H. pylori, non-nonsteroidal anti-inflammatory drug (NSAID) ulcer, surgical treatment, and conservative therapy for perforation and stenosis. Ninety clinical questions (CQs) were developed, and a literature search was performed for the CQs using the Medline, Cochrane, and Igaku Chuo Zasshi databases between 1983 and June 2012. The guideline was developed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. Therapy is initially provided for ulcer complications. Perforation or stenosis is treated with surgery or conservatively. Ulcer bleeding is first treated by endoscopic hemostasis. If it fails, surgery or interventional radiology is chosen. Second, medical therapy is provided. In cases of NSAID-related ulcers, use of NSAIDs is stopped, and anti-ulcer therapy is provided. If NSAID use must continue, the ulcer is treated with a proton pump inhibitor (PPI) or prostaglandin analog. In cases with no NSAID use, H. pylori-positive patients receive eradication and anti-ulcer therapy. If first-line eradication therapy fails, second-line therapy is given. In cases of non-H. pylori, non-NSAID ulcers or H. pylori-positive patients with no indication for eradication therapy, non-eradication therapy is provided. The first choice is PPI therapy, and the second choice is histamine 2-receptor antagonist therapy. After initial therapy, maintenance therapy is provided to prevent ulcer relapse.

    Despite so much contributions reported in the literature, the aetiology of the duodenal ulcer remains an enigmatic subject to the medical profession. Findings of Helicobacter pylori seem to have overshadowed the real issue, in that, how a small area of the duodenal mucosa could be inflicted with the acid-pepsin injury has not been questioned? One hundred and sixty-eight consecutive patients, presented with epigastric pain were included in the endoscopic study. The aim of the study was to find out the prevalence and its clinical importance on the sizes of the pyloric aperture in the aetiology of peptic ulcer disease. Demographic data on the sizes of the pyloric aperture were divided into two groups, in that, those up to 3 mm in diameter were included in one and those over the size of 3 mm in another. Among the 168 cases, the gastric ulcer was found in 12 and duodenal ulcer in 27 patients. The sex ratio of men to women was 1.4:1 found in the former and 8:1 in the latter. Among other findings, a knuckle of duodenal mucoa was noticed prolapsing through the large pyloric aperture. It could be postulated that a knuckle of the mucosa that keeps peeping through the pylorus acts as a mucosal plug in empty stomach, like a cork in the acid bottle. The main physiological function is to protect the mucosa from being damaged by the acid-pepsin injury or by the reflux of bile, but the tip of the plug seems to be subjected to such injury. Furthermore, the surface epithelial cells could also be subjected to ischaemic change while prolapsing through the pylorus. This may lead to reduced production of the mucosal gel and bicarbonate secretion, thus exposing the damaged mucosa to acid bath. This supports the concept, how a small area of the stomach or duodenum could be inflicted with ulceration.

    Background and Aims Histological and rapid urease tests to detect H. pylori in biopsy specimens obtained during peptic ulcer bleeding episodes (PUB) often produce false-negative results. We aimed to examine whether immunohistochemistry and real-time PCR can improve the sensitivity of these biopsies. Patients and Methods We selected 52 histology-negative formalin-fixed paraffin-embedded biopsy specimens obtained during PUB episodes. Additional tests showed 10 were true negatives and 42 were false negatives. We also selected 17 histology-positive biopsy specimens obtained during PUB to use as controls. We performed immunohistochemistry staining and real-time PCR for 16S rRNA, ureA, and 23S rRNA for H. pylori genes on all specimens. Results All controls were positive for H. pylori on all PCR assays and immunohistochemical staining. Regarding the 52 initially negative biopsies, all PCR tests were significantly more sensitive than immunohistochemical staining (p<0.01). Sensitivity and specificity were 55% and 80% for 16S rRNA PCR, 43% and 90% for ureA PCR, 41% and 80% for 23S rRNA PCR, and 7% and 100% for immunohistochemical staining, respectively. Combined analysis of PCR assays for two genes were significantly more sensitive than ureA or 23S rRNA PCR tests alone (p<0.05) and marginally better than 16S rRNA PCR alone. The best combination was 16S rRNA+ureA, with a sensitivity of 64% and a specificity of 80%. Conclusions Real-time PCR improves the detection of H. pylori infection in histology-negative formalin-fixed paraffin-embedded biopsy samples obtained during PUB episodes. The low reported prevalence of H. pylori in PUB may be due to the failure of conventional tests to detect infection. PMID:21625499

    Stroke is a common cause of death worldwide, but about 30% of ischemic stroke (IS) patients have no identifiable contributing risk factors. Because peptic ulcer disease (PUD) and vascular events share some common risk factors, we conducted a population-based study to evaluate the association between PUD and IS.We followed up a representative sample of 1 million residents of Taiwan using the National Health Insurance Research Database from 1997 to 2011. We defined patients who received medications for PUD and had related diagnosis codes as the PUD group, and a reference group matched by age and sex was sampled from those who did not have PUD. We also collected data on medical history and monthly income. The events of IS occurred after enrollment were compared between the 2 groups. The data were analyzed using Cox proportional hazard models at the 2-tailed significant level of 0.05.The PUD group had higher income and prevalence of hypertension, diabetes mellitus (DM), heart disease, and hyperlipidemia. They also had a higher risk of developing IS with an adjusted hazard ratio of 1.31 (95% confidence interval: 1.20-1.41). Other independent risk factors included male sex, older age, lower income, and co-morbidity of hypertension, diabetes mellitus (DM), and heart disease.PUD is a risk factor for IS, independent of conventional risk factors such as male sex, older age, lower income, and co-morbidity of hypertension, DM, and heart disease. Prevention strategies taking into account PUD should be developed and evaluated.

    Collagenous gastritis (CG) is characterized by patchy subepithelial collagen bands. Effective treatment and the clinical and histological outcome of CG in children are poorly defined. The aim of this study is to summarize the published literature on the clinical outcome and response to therapy of pediatric CG including two new cases. We performed a search in Pubmed, OVID for related terms; articles including management and clinical and/or endo-histologic follow up information were included and abstracted. Reported findings were pooled in a dedicated database including the corresponding data extracted from chart review in our patients with CG. Twenty-four patients were included (17 females) with a mean age of 11.7 years. The clinical presentation included iron deficiency anemia and dyspepsia. The reported duration of follow up (in 18 patients) ranged between 0.2-14 years. Despite most subjects presenting with anemia including one requiring blood transfusion, oral iron therapy was only documented in 12 patients. Other treatment modalities were antisecretory measures in 13 patients; proton pump inhibitors (12), or histamine-2 blockers (3), sucralfate (5), prednisolone (6), oral budesonide in 3 patients where one received it in fish oil and triple therapy (3). Three (13%) patients showed no clinical improvement despite therapy; conversely 19 out of 22 were reported with improved symptoms including 8 with complete symptom resolution. Spontaneous clinical resolution without antisecretory, anti-inflammatory or gastroprotective agents was noted in 5 patients (4 received only supplemental iron). Follow up endo-histopathologic data (17 patients) included persistent collagen band and stable Mononuclear cell infiltrate in 12 patients with histopathologic improvement in 5 patients. Neither collagen band thickness nor mononuclear cell infiltrate correlated with clinical course. Intestinal metaplasia and endocrine cell hyperplasia were reported (1) raising the concern of long

    Present article is devoted to the study of the correlation between vitamin B12 serum level, hyperhomocysteinaemia and dyslipidemia. During research there were discovered that the lowest vitamin B12 serum level and the highest homocysteine serum level have been registrated in associated pathology (ischemic heart disease and acid peptic disease according to long-term proton pump inhibitor use) patients. It was shown evident correlation between that changes and dyslipidemia. Тhe complex therapy that includes parenteral B12 supplementation leads to more effective correction of hyperhomocysteinaemia and dyslipidemia in patients with comorbidity of ischemic heart disease and acid peptic disease with long-term use of proton pump inhibitors.

The randomized, self- and placebo-controlled, double-blind, pilot study included 16 patients of the 2nd Department of Internal Medicine, Semmelweis University diagnosed with erosive gastritis. The instrumental analysis followed a qualitative (pre-intervention) assessment of the symptoms by the patient: lower heartburn (in the ventricle), upper heartburn (in the oesophagus), epigastric pain, regurgitation, bloating and dry cough. Medical diagnosis included a double-line upper panendoscopy followed by 30 min local inhomogeneous SMF-exposure intervention at the lower sternal region over the stomach with peak-to-peak magnetic induction of 3 mT and 30 mT m−1 gradient at the target site. A qualitative (post-intervention) assessment of the same symptoms closed the examination. Sham- or SMF-exposure was used in a double-blind manner. The authors succeeded in justifying the clinically and statistically significant beneficial effect of the SMF- over sham-exposure on the symptoms of erosive gastritis, the average effect of inhibition was 56% by p = 0.001, n = 42 + 96. This pilot study was aimed to encourage gastroenterologists to test local, inhomogeneous SMF-exposure on erosive gastritis patients, so this intervention may become an evidence-based alternative or complementary method in the clinical use especially in cases when conventional therapy options are contraindicated.

    Telomere shortening occurs with human aging in many organs and tissues and is accelerated by rapid cell turnover and oxidative injury. We measured average telomere length using quantitative real-time PCR in non-neoplastic gastric mucosa and assessed its relationship to H. pylori-related gastritis, DNA methylation, ulcer disease, and nonsteroidal anti-inflammatory drug (NSAID) usage. Gastric biopsies were obtained from 151 cancer-free subjects including 49 chronic NSAID users and 102 nonusers. Relative telomere length in genomic DNA was measured by real-time PCR. H. pylori infection status, histological severity of gastritis, and serum pepsinogens (PGs) were also investigated. E-cadherin (CDH1) methylation status was determined by methylation-specific PCR (MSP). Average relative telomere length of H. pylori-infected subjects was significantly shortened when compared to H. pylori-negative subjects (p = 0.002) and was closely associated with all histological parameter of gastritis (all p values <0.01) and CDH1 methylation (p = 0.0002). In H. pylori-negative subjects, NSAID users presented significantly shorter telomere length than nonusers (p = 0.028). Shorter telomere length was observed in duodenal and gastric ulcer patients compared with non-ulcer subjects among NSAID users. Telomere shortening is closely associated with severity of H. pylori-induced gastritis and CDH1 methylation status. Also, telomere shortening is accelerated by NSAID usage especially in H. pylori-negative subjects.

    The popularly exploited murine neonatal thymectomy experimental autoimmune gastritis (nTx:EAG) model requires the animal to be in a state of lymphopenia. Here we report on a novel murine immunization (without adjuvant) model that can establish a lasting gastritis. We demonstrate that the immunization model (imm:EAG) results in a bona fide autoimmune disease and define the resulting pathology and serology observed and compare it with that reported for human autoimmune gastritis. Immune cells present in the stomachs of imm:EAG gastritic mice include CD8 T cells, CD11b and Gr1 (granulocytes/monocytes) and B cells. We detected circulating antibodies of immunoglobulin G1 (IgG1) subclass, with some IgG(2a) and IgG(2b) reactive to stomach membranes and the parietal cell proton pump. The class and subclass of autoreactive antibodies resulting from imm:EAG suggest a T helper 1 (Th1)/Th2 immune response. We establish that both self-reactive T and B cells from BALB/cCrSlc imm:EAG gastritic mice have the potential to induce a gastritis in BALB/c syngeneic nu/nu recipients. We conclude that this model is likely to be superior to the currently popularly exploited nTx:EAG and provide insight into and an understanding of the mechanisms of and remedies for autoimmunity in an intact immune system.

    Background The association between proinflammatory cytokine gene polymorphisms and gastric diseases related to Helicobacter pylori varies by population and geographic area. Our objective was to determine if the IL-1B -511 T>C and -31 C>T polymorphisms and H. pylori vacA genotypes are associated with risk of chronic gastritis and gastric ulcer in a Mexican population. Methods We conducted endoscopic studies in 128 patients with symptoms of dyspepsia. We took two biopsies from the body, antrum, or ulcer edge from each patient, and classified our histopathological findings according to the Sydney System. H. pylori infection and vacA genotyping were accomplished via PCR from total DNA of the gastric biopsies. We confirmed the presence of anti-H. pylori serum IgG and IgM in 102 control subjects. In both case subjects and control subjects, the IL-1B -511 T>C polymorphism was genotyped by PCR-RFLPs and the IL-1B -31 C>T polymorphism was genotyped by pyrosequencing. Results Sixty-two point seven (62.7%) of the 102 control subjects were H. pylori-seropositive. Among the case subjects, 100 were diagnosed with chronic gastritis and 28 with gastric ulcer. We found that 77% of the patients with chronic gastritis and 85.7% of the patients with gastric ulcer were H. pylori-positive. The predominant H. pylori genotype was vacA s1m1 (58.4%) and the most frequent subtype was vacA s1. The -511 TC, (rs16944 -511 T>C) genotype and the -511C allele were associated with chronic gastritis (OR = 3.1, 95% CI = 1.4-6.8 and OR = 3.0, 95% CI = 1.4-6.0, respectively). The subjects carrying -31T (rs1143627 -31 C>T) were found to be at a higher risk of having chronic gastritis (OR = 2.8, 95% CI = 1.3-5.8). The IL-1B -511C/-31T haplotype was associated with chronic gastritis (OR = 2.1, 95% CI = 1.2-3.8) but not with gastric ulcer. Conclusions The H. pylori vacA genotypes identified herein were similar to those reported for other regions of Mexico. The vacA s1m1 genotype was not associated with

    The effects of aspirin and ibuprofen on pepsinogen secretion were studied in isolated human peptic cells prepared from endoscopically obtained biopsy specimens after collagenase digestion, mechanical disruption, and percoll gradient centrifugation. Pharmacological concentrations of aspirin and ibuprofen (10(-8)-10(-4) M), potentiated histamine (10(-6)-10(-4)M) and forskolin (10(-5)M) stimulated pepsinogen secretion without affecting basal secretion, acetylcholine (10(-6)M) stimulated pepsinogen secretion or cell vitality. Augmentation of secretagogue stimulated pepsinogen secretion was dependent on extracellular calcium because potentiation was abolished by calcium depletion of the medium. Cimetidine inhibited the potentiation effect on histamine but not on forskolin stimulated pepsinogen secretion, thus suggesting that this augmentation was independent of histamine H2 receptors. Of interest, potentiation was also independent of endogenous prostaglandin inhibition because exogenous addition of prostaglandin E2 and D2 increased both basal and acetylcholine stimulated pepsinogen secretion in a dose dependent way, but they did not modify histamine or histamine plus aspirin or ibuprofen stimulated pepsinogen secretion. In conclusion, aspirin and ibuprofen potentiate secretagogue stimulated pepsinogen secretion by dispersed human peptic cells and this might be an additional mechanism of non-steroidal anti-inflammatory drug (NSAID) induced gastric injury. This potentiation effect is regulated by calcium, independent of endogenous prostaglandin inhibition and seems to act on pepsinogen secretion at a post-receptor site. PMID:7797113

    Serum gastrin levels exceeding 1000 pg/ml (normal, <100) usually raise the suspicion for a neuroendocrine tumor (NET) that secretes gastrin. Rarely, such elevated gastrin levels are seen in patients with pernicious anemia which most commonly is associated with autoimmune gastritis (AG). AG can occur concomitantly with other autoimmune disorders including lymphocytic colitis (LC). Gastrin stimulates enterochromaffin-like cells which increase histamine secretion. Histamine excess can cause diarrhea as can bacterial overgrowth or LC. We present a 57-year-old woman with diarrhea, sporadic epigastric pain, and bloating. She also had a history of interstitial cystitis and took pentosan polysulfate and cetirizine. She had no history of ulcers, renal impairment or carcinoid syndrome. Fasting serum gastrin was 1846 pg/ml. Esophagoduodenal gastroscopy and biopsies revealed chronic gastritis and a pH of 7 with low stomach acid. Serum gastrin and plasma chromogranin A were suggestive of a gastrinoma or NET. Pernicious anemia was unlikely. Imaging studies did not reveal any tumor. Random colonic biopsy was compatible with LC, possibly explaining her diarrhea, although we also considered excessive histamine from elevated gastrin, bacterial overgrowth, and pentosan polysulfate which can cause diarrhea and be misleading in this setting, pointing to the diagnosis of gastrinoma. At 4 year follow-up in 2012, fasting serum gastrin was 1097 pg/ml and the patient asymptomatic taking only cetirizine for nasal allergies. This case illustrates that diarrhea may be associated with very high serum gastrin levels in the setting of chronic gastritis, LC, and interstitial cystitis (pentosan use), without clear evidence for a gastrinoma or NET. If no history of ulcers or liver metastases is present in such cases, watchful observation rather than an extensive/invasive and costly search for a NET may be justified. Considering the various forms of polyglandular syndrome, this may represent a

    Postherpetic neuralgia is the most common complication of herpes zoster which is caused by a reactivation of latent varicella zoster virus. The pathogenesis of postherpetic neuralgia may involve peripheral and central mechanisms. Reported risk factors for postherpetic neuralgia include female gender, old age, diminished cell-mediated immunity and nutritional deficiencies. Based on our clinical observation which revealed that peptic ulcer disease (PUD) is one of the common comorbidities in patients with postherpetic neuralgia, we hypothesize that herpes zoster patients with PUD may be at a greater risk for the development of postherpetic neuralgia due to their impaired cellular immunity and depressed nutritional status. Major causes of PUD include Helicobacter pylori infection and usage of ulcerogenic medications. Patients with H. pylori infection may develop T cell dysfunctions and nutritional deficiencies including vitamin C, iron, cobalamin, carotenes and alpha-tocopherol. Ulcerogenic medications such as nonsteroidal anti-inflammatory drugs and steroids have been found not only to be ulcerogenic but also immunosuppressive to T cells. In addition, usage of steroids and nonsteroidal anti-inflammatory drugs may cause deficiencies of alpha-tocopherol, carotenes, cobalamin, iron, zinc and vitamin C. Vitamin C, carotenes and alpha-tocopherol are anti-inflammatory and the major oxidant scavengers in the aqua phase and biomembranes. Deficiencies of these nutrients may induce dysregulated inflammation and oxidative damage leading to neuropathic pain in patients with herpes zoster. Furthermore, nutrient deficiencies including zinc, iron, cobalamin and vitamin C are associated with dysregulation of Ca(v)3.2 T-channels and N-methyl-D-aspartate receptors, upregulation of nitric oxide synthase, the increase of nitric oxide formation and dysfunction of central norepinephrine inhibitory pain pathway. Prospective cohort studies are suggested to test the hypothesis. We further

    Aim The purpose of the present study was to evaluate the number and proportion of various causes of upper gastrointestinal bleeding and actual numbers of non-NSAID, non-Helicobacter pylori (H.pylori) peptic ulcers seen in endoscopy of these patients. Background The number and the proportion of patients with non- H.pylori, non-NSAIDs peptic ulcer disease leading to upper gastrointestinal bleeding is believed to be increasing after eradication therapy for H.pylori. Patients and methods Medical records of patients referred to the emergency room of Taleghani hospital from 2010 with a clinical diagnosis of upper gastrointestinal bleeding (hematemesis, coffee ground vomiting and melena) were included in this study. Patients with hematochezia with evidence of a source of bleeding from upper gastrointestinal tract in endoscopy were also included in this study. Results In this study, peptic ulcer disease (all kinds of ulcers) was seen in 61 patients which were about 44.85% of abnormalities seen on endoscopy of patients. Among these 61 ulcers, 44 were duodenal ulcer, 22 gastric ulcer (5 patients had the both duodenal and gastric ulcers). Multiple biopsies were taken and be sent to laboratory for Rapid Urease Test and pathological examination. About 65.53% of patients had ulcers associated with H.pylori, 9.83% had peptic ulcer disease associated with NSAIDs and 11.47% of patients had ulcers associated with both H.pylori and consumption of NSAIDs. 13.11% of patients had non-NSAIDs non- H.pylori peptic ulcer disease. Conclusion The results of this study supports the results of other studies that suggest the incidence of H.pylori infection related with duodenal ulcer is common, and that non-H pylori and non-NSAIDs duodenal ulcer is also common.

    Autoimmune gastritis is an autoimmune and inflammatory condition that may predispose to gastric carcinoid tumors or adenocarcinomas. The early diagnosis of these tumors is important in order to decrease morbidity and mortality. Platelet indices such as mean platelet volume and plateletcrit levels increase in inflammatory, infectious and malign conditions. The primary aim of this study was to explore wheter platelet indices and red cell distribution width have any predictive role in the discrimination of autoimmune gastritis patients with and without gastric carcinoid tumors. Also secondary aim of this study was to investigate whether any changes exist betwenn autoimmune gastritis and functional dyspepsia patients by means of platelet indices. Plateletcrit (0.22 ± 0.06 vs. 0.20 ± 0.03%, p < 0.001) and red cell distribution width (16.11 ± 3.04 vs. 13.41 ± 0.95%, p < 0.001) were significantly higher in autoimmune gastritis patients compared to control group. Receiver operating curve analysis suggested that optimum plateletcrit cut-off point was 0.20% (AUC: 0.646), and 13.95% as the cut off value for red cell distribution width (AUC: 0.860). Although plateletcrit (0.22 ± 0.06 vs. 0.21 ± 0.04%, p = 0.220) and mean platelet volume (8.94 ± 1.44 vs. 8.68 ± 0.89 fl, p = 0.265) were higher in autoimmune gastritis patients without carcinoid tumor compared to patients with carcinoid tumors, these parameters were not statistically significant. Changes in plateletcrit and red cell distribution width values may be used as a marker in the discrimination of autoimmune gastritis and fucntional dyspepsia patients but not useful in patients with gastric carcinoid tumor type I.

    We investigated the prevalence of peptic ulcer in dyspeptic patients in China to analyze the influence of age, sex, and Helicobacter pylori (H. pylori) infection. The results showed that the prevalence of gastric and duodenal ulcer increased with age. In patients under 60 years old, the prevalence of duodenal and gastric ulcers in females was markedly lower than that in males, especially the prevalence of duodenal ulcer. The prevalence of duodenal ulcer and gastric ulcer in H. pylori-infected patients was markedly higher than in patients without H. pylori infection. In the patients under 60 years old, sex differences were still seen in both H. pylori-positive and H. pylori-negative patients. The prevalence of gastric and duodenal ulcers was markedly increased with age in both H. pylori-positive and H. pylori-negative patients. Multivariate logistic regression analysis showed that age, male sex, and H. pylori infection were three independent risk factors for gastric and duodenal ulcers.

    Objective: To perform and confirm a simplified diagnostic indicators scoring system for predicting peptic ulcer perforation (PUP). Methods: A case–control study was conducted including 812 consecutive patients with PUP from retrospective medical records. Each diagnostic indicator measurable at the time of admittance was analyzed by a multiple regression. Stepwise logistic regression was applied with backward elimination of statistically significant predictors from the full model, with P ≥ 0.05 for exclusion. The item scores were transformed from regression coefficients and computed to a total score. The risk of PUP was interpreted using total scores as a simple predictor. This system was internally validated in 218 consecutive patients and compared to existing systems. Results: A PUP risk score was determined from the diagnostic indicators associated with PUP: gender, age, nonsteroidal antiinflammatory drugs used, history of peptic ulcer, intense abdominal pain, guarding, X-ray free air positive, and referral from other hospitals. Item scores ranged from 0–6.0 and the total score ranged from 0–34.0. The area under the receiver operating characteristic curve shows that there was 91.73% accuracy in the total scores predicting the likelihood of PUP. The likelihood of PUP among low risk (scores <10.5), moderate risk (scores 11–21), and high risk (scores ≥ 21.5) patients was 0.13, 11.44, and 1.95, respectively. Conclusion: This scoring system is an effective diagnostic indicator for identifying the complex cases of PUP. It is a simple system and can help guide clinicians, providing them with a more efficient way to accurately subgroup patients while also reducing potential biases. PMID:23055764

    Background Ulcer perforation carries up to a 30% 1-year mortality rate. Intervention-related adverse events are among statistically significant predictors of 1-year mortality. A Natural Orifice Transluminal Endoscopic Surgical (NOTES) approach may be less invasive and may decrease procedure-related adverse events by diminishing the "second hit", thus leading to decreased morbidity and mortality. Aim To assess the feasibility of an endoscopic transluminal omental plug technique in patients with perforated gastroduodenal ulcers under laparoscopic guidance. Methods Patients with suspected acute gastroduodenal ulcer perforations were offered participation in this prospective pilot study. Closure of the perforation was attempted using NOTES omental plug technique. Demographic, clinical, endoscopic and radiographic data were abstracted, as well as morbidity, mortality and pilot data regarding quality of life (QOL). Results From February 2010 through Feb 2012, 17 patients presented to a tertiary care center with clinically suspected perforated ulcer. Of seven patients (mean age 79, range 64–89) who consented to the study, three underwent the study procedure. All patients had multiple comorbidities. Two patients presented with 4–6 mm perforated peptic ulcers and underwent successful laparoscopic-assisted NOTES omental and falciform ligament patch closure, respectively. Postoperative radiographic contrast studies showed no leak and patients were discharged home on postoperative days 3 and 4. The third patient had undergone enterocutaneous fistula repair with herniorrhaphy 6 weeks prior; a transluminal endoscopic approach was feasible; however, the omentum was under too much tension to be secured. This procedure was converted to an open omental patch repair. For all but one consented patient, obtaining QOL data was feasible. Conclusion Initial results from a laparoscopic-assisted NOTES approach for closure of perforated peptic ulcers appear promising and enable swift

    Objective To determine whether once-daily esomeprazole 40 mg or 20 mg compared with placebo reduces the incidence of peptic ulcers over 26 weeks of treatment in patients taking low-dose acetylsalicylic acid (ASA) and who are at risk for ulcer development. Design Multinational, randomised, blinded, parallel-group, placebo-controlled trial. Setting Cardiology, primary care and gastroenterology centres (n=240). Patients Helicobacter pylori-negative patients taking daily low-dose ASA (75–325 mg), who fulfilled one or more of the following criteria: age ≥18 years with history of uncomplicated peptic ulcer; age ≥60 years with either stable coronary artery disease, upper gastrointestinal symptoms and five or more gastric/duodenal erosions, or low-dose ASA treatment initiated within 1 month of randomisation; or age ≥65 years. All patients were ulcer-free at study entry. Interventions Once-daily, blinded treatment with esomeprazole 40 mg, 20 mg or placebo for 26 weeks. Main outcome measures The primary end point was the occurrence of endoscopy-confirmed peptic ulcer over 26 weeks. Results A total of 2426 patients (52% men; mean age 68 years) were randomised. After 26 weeks, esomeprazole 40 mg and 20 mg significantly reduced the cumulative proportion of patients developing peptic ulcers; 1.5% of esomeprazole 40 mg and 1.1% of esomeprazole 20 mg recipients, compared with 7.4% of placebo recipients, developed peptic ulcers (both p<0.0001 vs placebo). Esomeprazole was generally well tolerated. Conclusions Acid-suppressive treatment with once-daily esomeprazole 40 mg or 20 mg reduces the occurrence of peptic ulcers in patients at risk for ulcer development who are taking low-dose ASA.

    On 58 healthy subjects, it was evaluated in endoscopic and histopathologic form, the cytoprotective effect on the gastroduodenal mucosa, such of T.G.E 1 (misoprostol) as of SAMe, in the present of acute bleeding gastritis induced by 1300 mg aspirin in a single dose and during 2 hours. SAMe was given in progressive doses up to 500 mg, which were ingested simultaneously with aspirin, and so with Misoprostol in doses of 50 mg, showed an endoscopic score of 0 without microscopic lesion of the gastroduodenal mucosa, this was confirmed by the histopathology, where both drugs give a cytoprotection of the gastroduodenal mucosa by about 95% of total biopsies gastrointestinal mucosa. It is suggest that T.G.E.1 (misoprostol) and SAMe are choice drugs in the treatment of hemorrhagic gastritis.

    A double-blind, randomized trial was undertaken to compare the clinical, endoscopic and histological response to 6-weeks' treatment with hydrotalcite/dimethicone suspension or magnesium hydroxide/aluminum hydroxide suspension in 36 patients with symptomatic gastritis. Significantly more patients (P less than 0.05) showed symptomatic improvement in the antacid-treated group than in the hydrotalcite/dimethicone-treated group and more had a reduction in histological inflammatory scores (P less than 0.01), although there was little correlation between histology and symptoms. There was no evidence from this study that the bile acid binding and anti-foaming properties of hydrotalcite/dimethicone suspension were of any benefit in the treatment of patients with symptomatic gastritis.

    OBJECTIVE. Clinical implications of serum anti-Helicobacter pylori immunoglobulin G (IgG) titer were unclear. This study investigated the associations of serum anti-H. pylori IgG titer with grade of histological gastritis, mucosal bacterial density and levels of serum biomarkers, including pepsinogen (PG) I, PGII, PGI/II ratio and gastrin-17. MATERIAL AND METHODS. Study participants were from a screening program in northern China. Serum anti-H. pylori IgG measurements were available for 5922 patients with superficial gastritis. Serum anti-H. pylori IgG titer and serum biomarkers were measured using ELISA, and gastric biopsies were evaluated using standardized criteria. RESULTS. In patients with mild, moderate or severe superficial gastritis, the mean serum anti-H. pylori IgG titers were 17.3, 33.4 and 54.4 EIU (p for trend < 0.0001), respectively. As mucosal H. pylori density score increased from 0 to 3, the mean serum anti-H. pylori IgG titers also increased from 24.7 to 44.8 EIU (p for trend < 0.0001). Serum anti-H. pylori IgG titer was associated positively with serum PGI, PGII and gastrin-17 concentrations and negatively with PGI/II ratio, and the association was the strongest for PGII. The mean PGII concentration of the patients in the highest quartile of IgG titer was twice the mean concentration of the patients in the lowest quartile (17.2 vs. 8.6 EIU, p < 0.0001). CONCLUSIONS. Our results suggest that serum anti-H. pylori IgG titer was associated positively with grade of histological gastritis, mucosal bacterial density and concentrations of serum PGI, PGII and gastrin-17, and negatively with PGI/II ratio.

    The prevalence of use of peptic ulcer drugs in the Danish population is described at two points in time using registrations of applications for reimbursement. In 1977-81, the prevalence of use of cimetidine was 0.4% in men and 0.2% in women. In 1989-90, the prevalence of use of peptic ulcer drugs was 1.3% in men and 1.2% in women. The increase in prevalence was apparent in all age groups, but most pronounced at relatively old age. The median age of users increased from 55 years in 1977-81 to 63 years in 1989-90. The data indicated that a third of those who used peptic ulcer drugs in 1977-81 also used these drugs in 1989-90, conditional on surviving this period. The probability of becoming a long term user was highest for those who were 50-69 years in 1977-81. The incidence of gastric cancer was investigated in the cohort of persons who used cimetidine in 1977-81. An excess risk of gastric cancer was apparent in the first years after start of cimetidine use. This is thought to reflect a selection bias. Significantly increased incidence was also observed in women seven years or longer after start of cimetidine use (RR = 4.7; 95% CI: 1.7-10.3). This estimate was, however, based on only six cases, and a similar pattern was not observed in men. PMID:1358764

    Chronic urticaria (CU) is defined as the occurrence of spontaneous wheals for a duration of more than 6 weeks and is the most frequent skin disease, with prevalence ranging between 15 and 25%, and is a seriously disabling condition, with social isolation and mood changes causing a significant degree of dysfunction and quality of life impairment to many patients. The main clinical features of CU are the repeated occurrence of transient eruptions of pruritic wheals or patchy erythema on the skin that last less than 24 hours and disappear without sequelae. CU is often defined as chronic idiopathic urticaria (CIU) because the causes of CU remain unknown in the great majority (70-95%) of patients. Drugs, food, viruses, alimentary conservative substances or inhalant substances often seem to be involved in determining CIU skin flare. Despite a general agreement that bacteria infections and parasitic infestations can be involved in the pathogenesis of CIU, proven evidence of these relationships is lacking. The aim of the present study is to evaluate the prevalence of Helicobacter pylori (Hp) infection, and the extension and severity of gastritis in a group of CIU patients compared to controls and to evaluate the effectiveness of eradication of Hp on the CIU symptomatology, and the role of Hp infection in pathogenesis of CIU.

    We aimed to characterize microbiota of the gastric mucosa as it progress to intestinal type of cancer. Study included five patients each of non-atrophic gastritis (NAG), intestinal metaplasia (IM) and intestinal-type gastric cancer (GC). Gastric tissue was obtained and DNA extracted for microbiota analyses using the microarray G3 PhyloChip. Bacterial diversity ranged from 8 to 57, and steadily decreased from NAG to IM to GC (p = 0.004). A significant microbiota difference was observed between NAG and GC based on Unifrac-presence/absence and weighted-Unifrac-abundance metrics of 283 taxa (p < 0.05). HC-AN analyses based on presence/absence of 238 taxa revealed that GC and NAG grouped apart, whereas IM overlapped with both. An ordinated analyses based on weighted-Unifrac distance given abundance of 44 taxa showing significance across categories revealed significant microbiota separation between NAG and GC. This study is the first to show a gradual shift in gastric microbiota profile from NAG to IM to GC.

    The aim of this study was to evaluate the significance of an endoscopic atrophic border and irregular arrangement of collecting venules (IRAC) in the diagnosis of Helicobacter pylori (H. pylori)-induced gastritis. Upper gastrointestinal tract endoscopy was performed on 723 patients, who were screened them for H. pylori infection. Any patients who had undergone H. pylori eradication therapy were excluded from the study. The endoscopic atrophic border and IRAC in each patient were assessed. The H. pylori status was determined in the patients by combination of a serological test and/or histopathological examination. The H. pylori infection rates were 95.4% (455/477) in the group with an endoscopic atrophic border and 22.3% (55/246) in the group without an endoscopic atrophic border. In the diagnostic validity check, presence of an endoscopic atrophic border had a sensitivity of 89.2% and a specificity of 89.7%. Furthermore, the H. pylori infection rates were 95.5% (506/530) in the IRAC group and 2.1% (4/193) in the regular arrangement of collecting venules (RAC) group. In the diagnostic validity check, IRAC had a sensitivity of 99.2% and a specificity of 88.7%. In conclusion, the presence of an endoscopic atrophic border and IRAC are highly indicative of an H. pylori-infected gastric mucosa.

    In this paper, exfoliative cells of fur in 56 cases of chronic atrophied gastritis (CAG) with Cold or Heat syndrome was observed by means of microscopy and electron microscopy. With microscopy, the authors found that keratinization of epithelial cells of fur in Cold syndrome group of CAG were markedly fewer than those in Heat syndrome group (P less than 0.01); while pre-keratinization cells were much more than those in Heat syndrome group (P less than 0.01); the constituent ratio of complete keratinization cells of fur in the two groups were markedly different. With the electron microscopy, fibrosis changes was appeared in pre-keratinization cells of Cold syndrome patients with CAG; desmosome was disappeared; metachromasia was appeared in nucleus; fibrosis change in Heat syndrome group was not obvious. Cells were still joined to one another by fingered protrusion. There were bacterias in both Cold and Heat syndrome groups. The change of exfoliative cells of fur in Cold and Heat syndromes in CAG, probably, can offer us a microcosmic sign for its early differentiation or diagnosis.

    Helicobacter pylori is a major risk factor for chronic atrophic gastritis (CAG). A large variety of definitions of CAG have been used in epidemiologic studies in the past. The aim of this work was to systematically review and summarize estimates of the association between H. pylori infection and CAG according to the various definitions of CAG. Articles on the association between H. pylori infection and CAG published until July 2007 were identified. Separate meta-analyses were carried out for studies defining CAG based on gastroscopy with biopsy, serum pepsinogen I (PG I) only, the pepsinogen I/pepsinogen II ratio (PG I/PG II ratio) only, or a combination of PG I and the PG I/PG II ratio. Numbers of identified studies and summary odds ratios (OR) (95% confidence intervals) were as follows: gastroscopy with biopsy: n = 34, OR = 6.4 (4.0-10.1); PG I only: n = 13, OR = 0.9 (0.7-1.2); PG I/PG II ratio: n = 8, OR = 7.2 (3.1-16.8); combination of PG I and the PG I/PG II ratio: n = 20, OR = 5.7 (4.4-7.5). Studies with CAG definitions based on gastroscopy with biopsy or the PG I/PG II ratio (alone or in combination with PG I) yield similarly strong associations of H. pylori with CAG. The association is missed entirely in studies where CAG is defined by PG I only.

    A 24-week, double-blind, clinical trial of rabeprazole for the prevention of recurrent peptic ulcers caused by low-dose aspirin (LDA) has been reported, but trials for longer than 24 weeks have not been reported. The aim of this study is to assess the long-term efficacy and safety of rabeprazole for preventing peptic ulcer recurrence on LDA therapy. Eligible patients had a history of peptic ulcers on long-term LDA (81 or 100 mg/day) therapy. Patients with no recurrence of peptic ulcers at the end of the 24-week double-blind phase with rabeprazole (10- or 5-mg once daily) or teprenone (50 mg three times daily) entered the extension phase. Rabeprazole doses were maintained for a maximum of 76 weeks, including the double-blind 24-week period and the extension phase period (long-term rabeprazole 10- and 5-mg groups). Teprenone was randomly switched to rabeprazole 10 or 5 mg for a maximum of 52 weeks in the extension phase (newly-initiated rabeprazole 10- and 5-mg groups). The full analysis set consisted of 151 and 150 subjects in the long-term rabeprazole 10- and 5-mg groups, respectively, and the cumulative recurrence rates of peptic ulcers were 2.2 and 3.7%, respectively. Recurrent peptic ulcers were not observed in the newly-initiated rabeprazole 10- and 5-mg groups. No bleeding ulcers were reported. No clinically significant safety findings, including cardiovascular events, emerged. The use of long-term rabeprazole 10- and 5-mg once daily prevents the recurrence of peptic ulcers in subjects on low-dose aspirin therapy, and both were well-tolerated. PMID:26060354

    The correlation between the amount of peritoneal fluid and clinical parameters in patients with perforated peptic ulcer (PPU) has not been investigated. The authors' objective was to derive a reliable formula for determining the amount of peritoneal fluid in patients with PPU before surgery, and to evaluate the correlation between the estimated amount of peritoneal fluid and clinical parameters. We investigated 62 consecutive patients who underwent emergency surgery for PPU, and in whom prediction of the amount of accumulated intraperitoneal fluid was possible by computed tomography (CT) using the methods described by Oriuchi et al. We examined the relationship between the predicted amount of accumulated intraperitoneal fluid and that measured during surgery, and the relationship between the amount of fluid predicted preoperatively or measured during surgery and several clinical parameters. There was a significant positive correlation between the amount of fluid predicted by CT scan and that measured during surgery. When patients with gastric ulcer and duodenal ulcer were analyzed collectively, the predicted amount of intraperitoneal fluid and the amount measured during surgery were each associated with the period from onset until CT scan, perforation size, the Mannheim peritoneal index, and the severity of postoperative complications according to the Clavien-Dindo classification. Our present results suggest that the method of Oriuchi et al is useful for predicting the amount of accumulated intraperitoneal fluid in patients with PPU, and that this would be potentially helpful for treatment decision-making and estimating the severity of postoperative complications.

    For many years, peptic-tryptic digests of gliadin, known as Frazer's fraction III, have been used in investigations of gliadin effects. Potential contamination by the proteases pepsin and trypsin, however, was not considered. To investigate the influence of contaminating proteases on binding of gliadin peptides to rat small intestinal brush border membranes we compared binding characteristics of different gliadin digests. Binding of biotinylated probes was studied in dot blots and Western blots with an enhanced chemiluminescence system. In gliadin peptide preparations only contaminating trypsin, but not pepsin, was detectable by specific antisera. Digestion with insoluble proteases attached to cross-linked beaded agarose yielded gliadin peptides free of contaminating pepsin and trypsin. These peptides bound 30% less to brush border membranes. Using these peptides, there was no trypsin-typical binding pattern to low molecular mass membrane proteins in contrast to peptide preparations which contained contaminating trypsin. In conclusion contaminating trypsin might alter gliadin peptide binding characteristics by direct binding to brush border membranes and by interfering with interactions between gliadin peptides and brush border membranes.

    Aims. To investigate H. pylori infection rate and evaluate a combined set of tests for H. pylori diagnosis in Vietnamese patients with acute peptic ulcer bleeding (PUD). Methods. Consecutive patients with acute PUB were enrolled prospectively. Rapid urease test (RUT) with 3 biopsies was carried out randomly. Patients without RUT or with negative RUT received urea breath test (UBT) and serological and urinary H. pylori antibody tests. H. pylori was considered positive if RUT or any noninvasive test was positive. Patients were divided into group A (RUT plus noninvasive tests) and group B (only noninvasive tests). Results. The overall H. pylori infection rate was 94.2% (161/171). Groups A and B had no differences in demographic characteristics, bleeding severity, endoscopic findings, and proton pump inhibitor use. H. pylori-positive rate in group A was significantly higher than that in group B (98.2% versus 86.7%, p = 0.004). The positive rate of RUT was similar at each biopsy site but significantly increased if RUT results from 2 or 3 sites were combined (p < 0.05). Conclusions. H. pylori infection rate in Vietnamese patients with acute PUB is high. RUT is an excellent test if at least 2 biopsies are taken. PMID:28133477

    Introduction. The aim of this study was to compare the outcomes between laparoscopic and open omental patch repair (LOPR versus OR) in patients with similar presentation of perforated peptic ulcer (PPU). The secondary aim was to evaluate the outcomes according to the severity of peritonitis. Methods. All patients who underwent omental patch repair at two university-affiliated institutes between January 2010 and December 2014 were reviewed. Matched cohort between LOPR and OR groups was achieved by only including patients that had ulcer perforation <2 cm in size and symptoms occurring <48 hours. Outcome measures were defined in accordance with length of stay (LOS), postoperative complications, and mortality. Results. 148 patients met the predefined inclusion criteria with LOPR performed in 40 patients. Outcome measures consistently support laparoscopic approach but only length of hospital stay (LOS) achieved statistical significance (LOPR 4 days versus OR 5 days, p < 0.01). In a subgroup analysis of patients with MPI score >21, LOPR is also shown to benefit, particularly resulting in significant shorter LOS (4 days versus 11 days, p < 0.01). Conclusion. LOPR offers improved short-term outcomes in patients who present within 48 hours and with perforation size <2 cm. LOPR also proved to be more beneficial in high MPI cases. PMID:27722200

    Recent data on peptic ulcer and Helicobacter pylori colonization of the ventricle were discussed. Agreement was reached to re-adjust the pharmacological treatment of this condition. All patients for whom antibiotic therapy is considered should be examined by gastroscope. The bacterial agent should be proved by at least one out of several available methods. Two different established regimens are prescribed, either triple therapy with bismuth, metronidazole and tetracycline or double treatment without bismuth, for instance amoxicillin and omeprazole. Clinical control should take place after about eight weeks, with a "breath-test" in the case of duodenal ulcers, or with gastroscopy and a urease test. Many pointed out that treatment aimed at gastric acid reduction is to be preferred in cases of first occurrence of ventricular ulcers. Long-term acid reduction by drugs should not be offered to a patient until an attempt has been made to eradicate existing bacteria. No patient should be operated on before he being given antibacterial treatment. Treatment of non-ulcer dyspepsia with antibiotics has not shown to have an affect.

    Peptic ulcer (PU) disease has a high rate of occurrence and recurrence in Korean and the selection of drug for treatment is diverse. In this study, the therapeutical effectiveness of regimens including proton pump inhibitors (PPI) was compared with the single PPI therapy. The clinical data were collected from 1,658 patients having idiopathic or drug-induced PU complication from a Medical Center in Daegu, Korea, and analyzed retrospectively based on the results of endoscopic examination, the drug history and the therapeutic cost depending on drugs used. The comparison of complete healing rate and recurrence rate showed no significant differences between the single PPI groups and the combination group with antacids, prokinetic agent or mucosa protectants. However, the combination therapy of PPI with mucosa protectants gave a slightly better therapeutic outcome than single PPI treatment in gastric ulcer patients. Comparatively, the combination of PPI with antacids significantly reduced the therapeutic effectiveness in duodenal ulcer patients. The analysis of cost-based therapeutic effectiveness reveals that any economic benefits in PU treatment were not gained by the combination of other class of ulcer drugs. Even though the rapidity of healing rate was not considered, it can be concluded that the PPI combination therapy might be not desirable in PU treatment. Particularly triplet or quartet combination therapy in PPI regimen was absolutely economically ineffective therapy in spite of the increase of medication costs.

    The aim of this study was to conduct a national survey to evaluate the recent endoscopic treatment and drug therapy of peptic ulcer bleeding (PUB) patients and to compare practices in high and low case volume Hungarian workplaces. A total of 62 gastroenterology units participated in the six-month study. A total of 3033 PUB cases and a mean of 8.15 ± 3.9 PUB cases per month per unit were reported. In the 23 high case volume units (HCV), there was a mean of 12.9 ± 5.4 PUB cases/month, whereas in the 39 low case volume units (LCV), a mean of 5.3 ± 2.9 PUB cases/month were treated during the study period. In HCV units, endoscopic therapies for Forrest Ia, Ib, and IIa ulcers were significantly more often used than in LCV units (86% versus 68%; P = 0.001). Among patients with stigmata of recent haemorrhage (Forrest I, II), bolus + continuous infusion PPI was given significantly more frequently in HCV than in LCV units (49.6% versus 33.2%; P = 0.001). Mortality in HCV units was less than in LCV units (2.7% versus 4.3%; P = 0.023). The penetration of evidence-based recommendations for PUB management is stronger in HCV units resulting lower mortality. PMID:22988454

    The aim of this study is to discuss whether the methylation levels of Runx3 could be used as the early biomarker for predicting the prognosis in chronic atrophic gastritis (CAG) patients. A total of 200 subjects including 60 controls without CAG (Group 1), 70 patients with mild CAG (Group 2), and 70 patients with moderate and severe CAG (Group 3) were recruited for this cross-sectional investigation in the Department of Gastroenterology in Daqing Oilfield General Hospital from July 2013 to May 2014. The MlALDI-TOF-MS was used to measure the methylation levels of Runx3 in all of the subjects. Real-time quantitative reverse transcription polymerase chain reaction and western blotting were chosen to determine the expression levels of Runx3. The correlations between methylation levels of Runx3 among these CAG patients and their prognosis were shown by logistic regression models. The results demonstrated that the methylation levels of CpG13, CpG14, and CpG15 in Runx3 were higher in Group 3 than those in Groups 1 and 2 (P <0.05), whereas the mRNA and protein expression levels of Runx3 were lower in Group 3 than those in Groups 1 and 2 (P <0.05). There were significantly negative correlations between the methylation levels of Runx3 with its expression and the healing prognosis of CAG patients. In brief, this study proved that the hypermethylation modifications of CpG13, CpG14, and CpG15 in the promoter region of Runx3 could result in the down regulation of Runx3 expression to affect the prognosis of CAG. So the methylation levels of these CpG sites in Runx3 in the peripheral blood can be used as the biomarker for predicting the healing prognosis of CAG patients.

    The association between H. pylori infection and pancreatic cancer risk remains controversial. We conducted a nested case-control study with 448 pancreatic cancer cases and their individually matched control subjects, based on the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort, to determine whether there was an altered pancreatic cancer risk associated with H. pylori infection and chronic corpus atrophic gastritis. Conditional logistic regression models were applied to calculate odds ratios (ORs) and corresponding 95% confidence intervals (CIs), adjusted for matching factors and other potential confounders. Our results showed that pancreatic cancer risk was neither associated with H. pylori seropositivity (OR = 0.96; 95% CI: 0.70, 1.31) nor CagA seropositivity (OR = 1.07; 95% CI: 0.77, 1.48). We also did not find any excess risk among individuals seropositive for H. pylori but seronegative for CagA, compared with the group seronegative for both antibodies (OR = 0.94; 95% CI: 0.63, 1.38). However, we found that chronic corpus atrophic gastritis was non-significantly associated with an increased pancreatic cancer risk (OR = 1.35; 95% CI: 0.77, 2.37), and although based on small numbers, the excess risk was particularly marked among individuals seronegative for both H. pylori and CagA (OR = 5.66; 95% CI: 1.59, 20.19, p value for interaction < 0.01). Our findings provided evidence supporting the null association between H. pylori infection and pancreatic cancer risk in western European populations. However, the suggested association between chronic corpus atrophic gastritis and pancreatic cancer risk warrants independent verification in future studies, and, if confirmed, further studies on the underlying mechanisms.

    We have studied the effect of tripotassium dicitrato bismuthate on the peptic activity of gastric juice, both basal and pentagastrin-stimulated, from five healthy volunteers using porcine pepsin solution as a control. Tripotassium dicitrato bismuthate showed no inhibition of the proteolytic activity of either the pure porcine or the human pepsin in the gastric juice. The ulcer healing efficacy of tripotassium dicitrato bismuthate is unlikely to be related to a gastric anti-protease effect.

    In patients subjected to pylorogastrectomy with anterior gastroenterostomy (Billroth's operation II) the remaining gastric mucosa is exposed to the damaging action of bile with consequent reduction of locally generated prostaglandins. The purpose of the present study was to explore the correlation between PgE2 levels in such postgastrectomy patients before and after treatment with sulglycotide. Twelve patients with clinical, endoscopic and histological evidence of alkaline reflux gastritis were treated with sulglycotide in daily doses of 1600 mg for 30 days. At termination there was a definite clinical, endoscopic and histological improvement with significant (p less than 0.001) increase of PgE2 levels.

    The polymorphisms in trefoil factor (TFF) gene family that protect gastrointestinal epithelium might influence individual vulnerability to gastric cancer (GC) and atrophic gastritis. We used the Sequenom MassARRAY platform to identify the genotypes of TFF2 rs3814896 and TFF3 rs9981660 polymorphisms in 478 GC patients, 652 atrophic gastritis patients, and 724 controls. For the TFF2 rs3814896 polymorphism, in the subgroup aged ≤ 50 years, we found that AG+GG genotypes were associated with a 0.746-fold decreased risk of atrophic gastritis [p=0.023, 95% confidence interval (CI)=0.580-0.960], a 0.626-fold decreased risk of GC (p=0.005, 95% CI=0.451-0.868), and a 0.663-fold decreased risk of diffuse-type GC (p=0.034, 95% CI=0.452-0.970) compared with the common AA genotype. For the TFF3 rs9981660 polymorphism, in the male subgroup, individuals with variant AG+AA genotype were associated with a 0.761-fold decreased risk of diffuse-type GC compared with the common GG genotype (p=0.043, 95% CI=0.584-0.992). Additionally, we found that in subjects aged ≤ 50 years compared with common AA genotype, TFF2 rs3814896 AG+GG genotypes were associated with increased TFF2 mRNA levels in the total gastric cancer specimens and in the diffuse-type gastric cancer specimens; and in males aged ≤ 50 years compared with common GG genotype, TFF3 rs9981660 AA+AG genotypes were associated with TFF3 mRNA levels in diffuse-type gastric cancer tissues and their corresponding non-cancerous tissues. To our knowledge, this is the first report of an association between the TFF2 rs3814896 AG+GG genotypes and decreased risks of GC, diffuse-type GC, and atrophic gastritis in younger people aged ≤ 50 years, and an association between TFF3 rs9981660 AG+AA genotype and decreased risk of diffuse-type GC in men. Moreover, we found that TFF2 rs3814896 AG+GG genotypes in people aged ≤ 50 years and TFF3 rs9981660 AG+AA genotypes in younger males with diffuse-type GC were associated with higher levels of

    Granulomas are rarely seen in gastric biopsies mostly as an involvement of granulomatous diseases like sarcoidosis, Crohn's disease, infections, neoplasms, and vasculitis. Here, we claim cyanoacrylate as a foreign body type granuloma-causing agent in the stomach after vascular embolisation. We present cyanoacrylate associated gastric changes of three cases: two endoscopic biopsies and one gastric resection. In two cases, cyanoacrylate associated ulcers and granulomatous inflammation were observed in gastric mucosal biopsies following endoscopic examination after 7 months and 6 years of the glue injections, respectively. In the third case, the cyanoacrylate injection was performed 2 months prior to the surgery. Then the patient underwent distal pancreatectomy for pancreatic adenocarcinoma and during the operation a gastric mass was resected with a suspicion of tumoral infiltration. These three cases demonstrated that glue exposure causes active chronic inflammation with foreign body type granulomas, mucosal ulceration, and bleeding in the gastric mucosa. Even further, it can induce mass formation in the injection sites. PMID:28203472

    Abstract Patients with chronic kidney disease (CKD) who had peptic ulcer bleeding (PUB) may have more adverse outcomes. This population-based cohort study aimed to identify risk factors that may influence the outcomes of patients with CKD and PUB after initial endoscopic hemostasis. Data from 1997 to 2008 were extracted from the National Health Insurance Research Database in Taiwan. We included a cohort dataset of 1 million randomly selected individuals and a dataset of patients with CKD who were alive in 2008. A total of 18,646 patients with PUB were screened, and 1229 patients admitted for PUB after endoscopic hemostasis were recruited. The subjects were divided into non-CKD (n = 1045) and CKD groups (n = 184). We analyzed the risks of peptic ulcer rebleeding, sepsis events, and mortality among in-hospital patients, and after discharge. Results showed that the rebleeding rates associated with repeat endoscopic therapy (11.96% vs 6.32%, P = 0.0062), death rates (8.7%, vs 2.3%, P < 0.0001), hospitalization cost (US$ 5595±7200 vs US$2408 ± 4703, P < 0.0001), and length of hospital stay (19.6 ± 18.3 vs 11.2 ± 13.1, P < 0.0001) in the CKD group were higher than those in the non-CKD group. The death rate in the CKD group was also higher than that in the non-CKD group after discharge. The independent risk factor for rebleeding during hospitalization was age (odds ratio [OR], 1.02; P = 0.0063), whereas risk factors for death were CKD (OR, 2.37; P = 0.0222), shock (OR, 2.99; P = 0.0098), and endotracheal intubation (OR, 5.31; P < 0.0001). The hazard ratio of rebleeding risk for aspirin users after discharge over a 10-year follow-up period was 0.68 (95% confidence interval [CI]: 0.45–0.95, P = 0.0223). On the other hand, old age (P < 0.0001), CKD (P = 0.0090), diabetes (P = 0.0470), and congestive heart failure (P = 0.0013) were the independent risk factors for death after discharge.

    Helicobacter pylori infection is associated with chronic gastritis, peptic ulceration, and gastric carcinoma. The potential role of CD95-mediated apoptosis was investigated in a panel of gastric biopsies obtained from patients with H. pylori-associated chronic gastritis (n = 29) and with noninfected normal mucosa (n = 10). Immunohistochemistry revealed increased CD95 receptor expression in epithelial and lamina propria cells in chronic gastritis. By in situ hybridization, CD95 ligand mRNA was absent or low in normal mucosa but expressed at high levels in lamina propria lymphocytes and, unexpectedly, in epithelial cells in chronic gastritis. Apoptotic cells were rare in normal mucosa but were observed regularly in chronic gastritis in close proximity to CD95 ligand mRNA expression throughout the epithelial and lamina propria cells. In a functional analysis gastric epithelial cell lines were incubated with supernatants of H. pylori. Treatment with the cytotoxic isolate H. pylori 60190 but not with the noncytotoxic isolate Tx30a upregulated CD95 in up to 50% of gastric epithelial cells and induced apoptosis in these cells. H. pylori-induced apoptosis was partially prevented by blocking CD95, demonstrating the functional role of the CD95 system. These findings suggest that H. pylori-associated chronic gastritis involves apoptosis of gastric epithelial cells by activation of the CD95 receptor and ligand system. PMID:9788963

    2000-01-01

    OBJECTIVE Nonsteroidal anti-inflammatory drugs (NSAIDs) increase the risk of peptic ulcer disease by 5- to 7-fold in the first 3 months of treatment. This study examined the relative cost-effectiveness of different strategies for the primary prevention of NSAID-induced ulcers in patients that are starting NSAID treatment. MEASUREMENTS AND MAIN RESULTS A decision analysis model was developed to compare the cost-effectiveness of 6 prophylactic strategies relative to no prophylaxis for patients 65 years of age starting a 3-month course of NSAIDs: (1) testing for Helicobacter pylori infection and treating those with positive tests; (2) empiric treatment of all patients for Helicobacter pylori; (3) conventional-dose histamine2receptor antagonists; (4) high-dose histamine2receptor antagonists; (5) misoprostol; and (6) omeprazole. Costs were estimated from 1997 Medicare reimbursement schedules and the Drug Topics Red Book. Empiric treatment of Helicobacter pylori with bismuth, metronidazole, and tetracycline was cost-saving in the baseline analysis. Selective treatment of Helicobacter pylori, misoprostol, omeprazole, and conventional-dose or high-dose histamine2receptor antagonists cost $23,800, $46,100, $34,400, and $15,600 or $21,500 per year of life saved, respectively, relative to prophylaxis. The results were sensitive to the probability of an ulcer, the probability and mortality of ulcer complications, and the cost of, efficacy of, and compliance with prophylaxis. The cost-effectiveness estimates did not change substantially when costs associated with antibiotic resistance of Helicobacter pylori were incorporated. CONCLUSIONS Several strategies for primary prevention of NSAID-induced ulcers in patients starting NSAIDs were estimated to have acceptable cost-effectiveness relative to prophylaxis. Empirically treating all patients for Helicobacter pylori with bismuth, metronidazole, and tetracycline was projected to be cost-saving in older patients. PMID:10886475

    Application of minimal access surgery in acute care surgery is limited due to various reasons. Laparoscopic omental patch repair (LOPR) for perforated peptic ulcer (PPU) surgery is safe and feasible but not widely implemented. We report our early experience of LOPR with emphasis on strict selection criteria. This is a descriptive study of all patients operated on for PPU at academic university-affiliated institutes from December 2010 to February 2012. All the patients who were operated on for LOPR were included as the study population and their records were studied. Perioperative outcomes, Boey score, Mannheim Peritonitis Index (MPI), and physiologic and operative severity scores for enumeration of mortality and morbidity (POSSUM) scores were calculated. All the data were tabulated in a Microsoft Excel spreadsheet and analyzed using Stata Version 8.x. (StataCorp, College Station, TX, USA). Fourteen patients had LOPR out of a total of 45 patients operated for the PPU. Mean age was 46 years (range 22−87 years). Twelve patients (86%) had a Boey score of 0 and all patients had MPI < 21 (mean MPI = 14). The predicted POSSUM morbidity and mortality were 36% and 7%, respectively. Mean ulcer size was 5 mm (range 2−10 mm), mean operating time was 100 minutes (range 70−123 minutes) and mean length of hospital stay was 4 days (range 3−6 days). There was no morbidity or mortality pertaining to LOPR. LOPR should be offered by acute care surgical teams when local expertise is available. This can optimize patient outcomes when strict selection criteria are applied. PMID:25692444

    OBJECTIVE. Use of selective serotonin reuptake inhibitors (SSRIs) increases the risk of upper gastrointestinal bleeding and this risk is amplified by concomitant use of non-steroidal anti-inflammatory drugs (NSAIDs). The aim of the study was to examine the impact of SSRI use alone or in combination with NSAIDs on 30-day mortality after peptic ulcer bleeding (PUB). MATERIAL AND METHODS. A population-based cohort study of patients with a first hospitalization with PUB in three Danish counties was carried out between 1991 and 2005 using medical databases. We calculated 30-day mortality rate ratios (MRRs) associated with the use of SSRIs, alone or in combination with NSAIDs, adjusted for important covariates. RESULTS. Of 7415 patients admitted with PUB, 5.9% used SSRIs only, and 3.8% used SSRIs in combination with NSAIDs, with a 30-day mortality of 11.8% and 11.3%, respectively. Compared with patients who used neither SSRIs nor NSAIDs, the adjusted 30-day MRR was 1.02 (95% CI: 0.76-1.36) for current users of SSRIs and 0.89 (0.62-1.28) for the combined use of SSRIs with NSAIDs. There was a 2.11-fold (95% CI 1.35-3.30) increased risk of death associated with SSRI use starting within 60 days of admission; for those younger than 80 years, the adjusted MRR was 1.54 (0.72-3.29), and 2.57 (1.47-4.49) for those older than 80 years. CONCLUSIONS. Use of SSRIs, alone or in combination with NSAIDs, was not associated with increased 30-day mortality following PUB. However, increased mortality was found in patients who started SSRI therapy, particularly among those older than 80 years. We can only speculate on whether this finding is due to pharmacological action or confounding factors.

    Abstract Little is known about the effect of air pollution on the gastrointestinal (GI) system. We investigated the association between long-term exposures to outdoor fine particles (PM2.5) and hospitalization for peptic ulcer diseases (PUDs) in a large cohort of Hong Kong Chinese elderly. A total of 66,820 subjects aged ≥65 years who were enrolled in all 18 Government Elderly Health Service centers of Hong Kong participated in the study voluntarily between 1998 and 2001. They were prospectively followed up for more than 10 years. Annual mean exposures to PM2.5 at residence of individuals were estimated by satellite data through linkage with address details including floor level. All hospital admission records of the subjects up to December 31, 2010 were retrieved from the central database of Hospital Authority. We used Cox regression to estimate the hazard ratio (HR) for PUD hospitalization associated with PM2.5 exposure after adjustment for individual and ecological covariates. A total of 60,273 subjects had completed baseline information including medical, socio-demographic, lifestyle, and anthropometric data at recruitment. During the follow-up period, 1991 (3.3%) subjects had been hospitalized for PUD. The adjusted HR for PUD hospitalization per 10 μg/m3 of PM2.5 was 1.18 (95% confidence interval: 1.02–1.36, P = 0.02). Further analysis showed that the associations with PM2.5 were significant for gastric ulcers (HR 1.29; 1.09–1.53, P = 0.003) but not for duodenal ulcers (HR 0.98; 0.78 to 1.22, P = 0.81). Long-term exposures to PM2.5 were associated with PUD hospitalization in elder population. The mechanism underlying the PM2.5 in the development of gastric ulcers warrants further research.

    Chronic gastritis associated with H. pylori infection causes oxidative stress in the stomach. This study aimed to evaluate the therapeutic effects of coenzyme q10 among gastric patients infected by H. pylori. By a clinical trial, chronic gastric patients infected by H. pylori were randomly divided into 2 groups: intervention and placebo. The placebo group received a standard triple therapy regimen, and the intervention group received the triple regimen + coenzyme Q10 (CoQ10). Mean inflammation score; serum levels of 3 serum markers were then compared. A total of 100 participants of whom 67% were female were evaluated. The mean age of participants was 59.4 ± 11.4 years. The mean inflammation score was considerably decreased at the end of the study, in the intervention group. The mean levels of total antioxidant capacity (TAC) and glutathione peroxidase (GPx) at the end of the study were reduced among the triple therapy group (P < .05, P =.03 respectively). The mean levels of TAC and GPx were significantly higher among the intervention group at the end of the study compared with those at the start of the study. The combination of triple therapy with CoQ10 demonstrated an effective outcome on the mucosal inflammation, and stress oxidative in patients with chronic gastritis.

    Background: Barium radiographic studies have suggested the importance of evaluating areae gastricae pattern for the diagnosis of gastritis. Significance of endoscopic appearance of areae gastricae in the diagnosis of chronic atrophic fundic gastritis (CAFG) was investigated by image-enhanced endoscopy. Materials and Methods: Endoscopic images of the corpus lesser curvature were studied in 50 patients with CAFG. Extent of CAFG was evaluated with autofluorescence imaging endoscopy. The areae gastricae pattern was evaluated with 0.2% indigo carmine chromoendoscopy. Micro-mucosal structure was examined with magnifying chromoendoscopy and narrow band imaging. Results: In patients with small extent of CAFG, polygonal areae gastricae separated by a narrow intervening part of areae gastricae was observed, whereas in patients with wide extent of CAFG, the size of the areae gastricae decreased and the width of the intervening part of areae gastricae increased (p < 0.001). Most areae gastricae showed a foveola-type micro-mucosal structure (82.7%), while intervening part of areae gastricae had a groove-type structure (98.0%, p < 0.001). Groove-type mucosa had a higher grade of atrophy (p < 0.001) and intestinal metaplasia (p < 0.001) compared with foveola type. Conclusions: As extent of CAFG widened, multifocal groove-type mucosa that had high-grade atrophy and intestinal metaplasia developed among areae gastricae and increased along the intervening part of areae gastricae. Our observations facilitate our understanding of the development and progression of CAFG. PMID:22515361

    Assessment of health status of the population - the most important issue in preventive medicine. The objective of this work - to determine the possibility of nonendoscopic screening for gastroduodenal pathology, by the example of atrophic gastritis, in mass medical examinations of working residents in Moscow. Minimally invasive diagnostic test system GastroPanel ("Biohit", Finland) has been used. It allows with the ELISA method to determine both serum indicators of the function of the stomach -pepsinogen 1, gastrin 17 and the presence of H. pylori infection. 758 persons have been examined. The performed study confirms the possibility with the use of a set of mentioned indicators to identify individuals suspected for the presence of gastroduodenal disorders, especially atrophic gastritis, recognized as a precancerous condition. The use in preventive medicine complex diagnostic system, firstly, will make assessment of the health of the population more correct, increase the effectiveness of preventive measures and quality of life, and secondly, will contribute to the diagnosis of diseases of the stomach and duodenum in the early stages.

    Phlegmonous gastritis is a rare bacterial infection of the gastric wall, which progress rapidly. It is characterized by a purulent inflammation that can affect the entire gastrointestinal tract and presents a high mortality rate. We are reporting a case of phlegmonous gastritis in an HIV-seropositive man successfully treated with antibiotics. Moreover, a review of the English andSpanish literature is carried out, from 1980 to the present time.The most frequently involved microorganism is Streptococcus spp. (57 %), but the polimicrobial infection is also frequent (17 %). The most important symptom is the intensive epigastric pain associated with vomits and most cases were diagnosed by CT and/or fibrogastroscopy. There are many existing risk factors described.The main one is the immunesuppression, although in 40 % of the cases no risk factors were identified. The global mortality is 27 % without identifying significant differences between antibiotics and surgical treatment, for that reason it is recommended to initiate antibiotic treatment right from the beginning and postponing surgery for the refractory cases and complications.

  11. Th1, Th2 and Th17 Effector T Cell-Induced Autoimmune Gastritis Differs in Pathological Pattern and in Susceptibility to Suppression by Regulatory T Cells

    Th cells can be subdivided into IFNγ-secreting Th1, IL-4/IL-5 secreting Th2, and IL-17 secreting Th17 cells. We have evaluated the capacity of fully differentiated Th1, Th2, and Th17 cells derived from a mouse bearing a transgenic TCR specific for the gastric parietal cell antigen, H/K ATPase, to induce autoimmune gastritis after transfer to immunodeficient recipients. We have also determined the susceptibility of the disease induced by each of the effector T cell types to suppression by polyclonal regulatory T cells (Treg) in vivo. Each type of effector cell induced autoimmune gastritis with distinct histological patterns. Th17 cells induced the most destructive disease with cellular infiltrates composed primarily of eosinophils accompanied by high levels of serum IgE. Polyclonal Treg could suppress the capacity of Th1 cells, moderately suppress Th2 cells, but could only suppress Th17 induced disease at early time points. The major effect of the Treg was to inhibit the expansion of the effector T cells. However, effector cells isolated from protected animals were not anergic and were fully competent to proliferate and produce effector cytokines ex vivo. The strong inhibitory effect of polyclonal Treg on the capacity of some types of differentiated effector cells to induce disease provides an experimental basis for the clinical use of polyclonal Treg in the treatment of autoimmune disease in man.

    The Mongolian gerbil is an excellent animal model for Helicobacter pylori-induced gastritis in humans. In this study, initially low colonization rates of the H. pylori strains ATCC 43504, SS1, or HP87 inoculated into gerbils caused difficulties in establishing this model. In order to increase the colonization ability and pathogenicity, the clinical HP87 isolate was selected for adaptation to the gerbil stomach by multiple in vivo passages through gerbils. Development of gastritis was examined histologically at 4-52 weeks after infection. The proportion of gerbils which tested positive for H. pylori by culture at four weeks after inoculation gradually increased from 11.1% of gerbils inoculated with HP87 without prior in vivo passage (P0) to 100% of gerbils inoculated with HP87 with seven in vivo passages (P7). In addition, adaptation of HP87 resulted in more severe histopathological changes. Gerbils infected with adapted HP87 (P7) exhibited severe infiltration by monomorphonuclear and polymorphonuclear leukocytes in the mucosa, submucosa, and subserosa of the gastric antrum, as well as epithelial changes consisting of hyperplasia, erosion, and ulceration. Histopathological changes increased in severity from four to 52 weeks after infection. Adaptation of HP87 during its passages through gerbils could be due to genetic changes in bacterial colonization factors. Identification of these changes might be useful to understand the underlying mechanism of gastric adaptation and pathogenesis of H. pylori.

    Two randomized groups of ulcer patients were compared. 102 patients of group 1 were treated with synthetic antioxidants (dibunol, probucol, emoxipine), while 100 patients of group 2 received a conventional treatment. Treatment results in group 1 appeared better: shortening of ulcer scarring, higher percentage of ulcer healing for 2 and 4 weeks, fall in the number of relapses during the first year of the follow-up, improvement in lipid peroxidation and antioxidant activity.
