    Oxidative stress occurs in inflammation of gastric mucosa. The role of zinc in modulating oxidative stress has recently been recognized. Zn deficiency results in an increased sensitivity to oxidative stress and have a higher risk of musoca damage in inflammation. The aim of this study was to determine wheather chronic inflammation affects on the concentration of Zn2+ ions in gastric mucosa of patients with chronic gastritis. Forthy-three patients with chronic gastitis were enrolled. Patients were endoscoped. Histology and scoring of gastritis was performed following the guidelines of the updated Sydney system. Endoscopic finding of mucosa were scored according to a Lanza scoring system. The diagnosis of Helicobacter pylori (H. pylori) infection, histopathologic changes, intensity of inflammation and zinc concentration were determined from biopsies of gastric mucosa. The atomic absorption spectrophotometer was used to determine tissue concentrations of zinc. Twenty of 43 patients with chronic gastritis were uninfected by H. pylori. There was no statistically significant difference in tissue concentrations of zinc between H. pylori-positive and H. pylori-negative patients. From those infected patients 53.3% had chronic active gastritis. There was no statistically significant difference in tissue concentrations of zinc between patients with chronic active gastritis and patients with chronic inactive gastritis (p = 0.966). Zn in antrum showed positive correlation with density of H. pylori in antrum (Spearman' rho = 0.481, p = 0.020), negative correlation with density of H. pylori in corpus (Spearman' rho = -0.492, p = 0.017) and with zinc in corpus (Spearman' rho = 0.631, p =0.001). Tissue concentration of zinc was not affected by chronic inflammation of gastric mucosa in patients with chronic gastritis.

    Abstract 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.

    Chronic gastritis is one of the most common findings at upper endoscopy in the general population, and chronic atrophic gastritis is epidemiologically associated with the occurrence of gastric cancer. However, the current status of diagnosis and treatment of chronic gastritis in China is unclear. A multi-center national study was performed; all patients who underwent diagnostic upper endoscopy for evaluation of gastrointestinal symptoms from 33 centers were enrolled. Data including sex, age, symptoms and endoscopic findings were prospectively recorded. Totally 8892 patients were included. At endoscopy, 4389, 3760 and 1573 patients were diagnosed to have superficial gastritis, erosive gastritis, and atrophic gastritis, respectively. After pathologic examination, it is found that atrophic gastritis, intestinal metaplasia and dysplasia were prevalent, which accounted for 25.8%, 23.6% and 7.3% of this patient population. Endoscopic features were useful for predicting pathologic atrophy (PLR = 4.78), but it was not useful for predicting erosive gastritis. Mucosal-protective agents and PPI were most commonly used medications for chronic gastritis. The present study suggests non-atrophic gastritis is the most common endoscopic finding in Chinese patients with upper GI symptoms. Precancerous lesions, including atrophy, intestinal metaplasia and dysplasia are prevalent in Chinese patients with chronic gastritis, and endoscopic features are useful for predicting pathologic atrophy.

    Fasting gastrin levels in serum were measured in 49 patients with different types of chronic gastritis and in matched controls. In 15 patients with established pernicious anaemia the mean (± S.E. of mean) level of gastrin was greatly raised (699 ± 99 pg/ml). In 17 patients with chronic atrophic gastritis, seropositive for parietal cell antibody but with adequate vitamin-B12 absorption, the level was also raised (476 ± 74 pg/ml). By contrast, in “simple” atrophic gastritis seronegative for parietal cell antibody the gastrin levels were significantly lower for both diffuse atrophic gastritis (129 ± 31 pg/ml) and multifocal gastritis (14 ± 4 pg/ml). These levels were similar to those in the controls (46 ± 7 pg/ml). The mechanism of the raised gastrin levels remains uncertain, but neither achlorhydria nor in vivo action of the parietal cell antibody wholly accounted for the hypergastrinaemia. We conclude that hypergastrinaemia is characteristic of gastritis associated with autoimmune reactions to gastric antigens and pernicious anaemia and that a raised serum gastrin is a useful marker of the type of gastritis that tends to progress to the gastric lesion of pernicious anaemia. The findings suggest that this type of gastritis is an essentially different disease from “simple” atrophic gastritis, and the differences in gastrin levels may be due to sparing of the antral mucosa in the autoimmune type but not in “simple” gastritis.

    Digestive disorders represent the most common metformin side effects for type 2 diabetes. The mechanism of these metformin side effects is unclear. The aim of this study was to assess whether asymptomatic chronic gastritis could influence metformin tolerance in patients with type 2 diabetes. Demographic, anthropometric, ultrasound and laboratory data were obtained from 144 metformin naïve patients with diabetes. The diagnosis of chronic gastritis was based on endoscopic and histopathological examination, and H. pylori infection was assessed based on (13) C urea breath test (UBT). All subjects started metformin at 500 mg/day and increasing progressively to 1500 mg/day over 4 weeks. A score of gastrointestinal side effects (abdominal pain, diarrhoea, nausea, vomiting, bloating and anorexia) was assessed each week, and metformin dose was adjusted as appropriate. Based on endoscopy, 64 patients were categorized as non-gastritis subjects and 80 as chronic gastritis subjects. At baseline, there is no statistical difference in gastrointestinal symptoms between two groups. With metformin, the mean scores for gastrointestinal symptoms in the non-gastritis and gastritis subjects were 1·02 ± 1·71 vs. 2·18 ± 2·05 (P = 0·001), 0·20 ± 0·65 vs. 0·50 ± 0·89 (P = 0·022), 0 vs. 0·06 ± 0·24 (P = 0·024) and 1·08 ± 1·03 vs. 1·71 ± 1·66 (P = 0·028). The mean final metformin dose used by gastritis subjects was 706·24 ± 568·90 mg, significantly less than the mean dose used by non-gastritis subjects (1101·56 ± 578·58 mg, P = 0·001). After adjustment for age and sex, the odds ratio (OR) for a final metformin dose of less than 1500 mg/day was found to be 2·76 (95% CI 1·38-5·53, P = 0·004) for chronic gastritis subjects. The OR for a final metformin dose of less than 1000 mg/day was found to be 3·98 (95% CI 1·91-8·27, P = 0·001) for chronic gastritis subjects. Our data suggest that pre-existing non-symptomatic gastritis was associated with metformin

    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. Copyright © 2014.

    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. © 2016 APMIS.

  10. Metabolic markers and microecological characteristics of tongue coating in patients with chronic gastritis

    PubMed Central

    2013-01-01

    Background In Traditional Chinese Medicine (TCM), tongue diagnosis has been an important diagnostic method for the last 3000 years. Tongue diagnosis is a non-invasive, simple and valuable diagnostic tool. TCM treats the tongue coating on a very sensitive scale that reflects physiological and pathological changes in the organs, especially the spleen and stomach. Tongue coating can diagnose disease severity and determine the TCM syndrome (“Zheng” in Chinese). The biological bases of different tongue coating appearances are still poorly understood and lack systematic investigation at the molecular level. Methods Tongue coating samples were collected from 70 chronic gastritis patients and 20 normal controls. 16S rRNA denatured gradient gel electrophoresis (16S rRNA–DGGE) and liquid chromatography and mass spectrometry (LC–MS) were designed to profile tongue coatings. The statistical techniques used were principal component analysis and partial least squares–discriminate analysis. Results Ten potential metabolites or markers were found in chronic gastritis patients, including UDP-D-galactose, 3-ketolactose, and vitamin D2, based on LC–MS. Eight significantly different strips were observed in samples from chronic gastritis patients based on 16S rRNA–DGGE. Two strips, Strips 8 and 10, were selected for gene sequencing. Strip 10 sequencing showed a 100% similarity to Rothia mucilaginosa. Strip 8 sequencing showed a 96.2% similarity to Moraxella catarrhalis. Conclusions Changes in glucose metabolism could possibly form the basis of tongue coating conformation in chronic gastritis patients. The study revealed important connections between metabolic components, microecological components and tongue coating in chronic gastritis patients. Compared with other diagnostic regimens, such as blood tests or tissue biopsies, tongue coating is more amenable to, and more convenient for, both patients and doctors. PMID:24041039

    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 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

    The presence and degree of manifestation of Campylobacter (Helicobacter) pylori in gastroduodenal mucosa were studied in 100 patients (56 men, mean age 51.4 years, and 44 women, mean age 46.5 years) with endoscopically proved chronic erosive gastritis (52 patients), erosive duodenitis (36 patients) and erosive gastroduodenitis (12 patients). The examinations revealed the presence of Campylobacter (Helicobacter) pylori in mean 77% of the patients with erosive gastritis, duodenitis and gastroduodenitis. Campylobacter (Helicobacter) pylori was found most often in patients with chronic erosive duodenitis--83.3%, whereas in the patients with erosive gastritis it was found in 73.07%. In 83.33% of the patients with chronic erosive gastritis, duodenitis and gastroduodenitis the campylobacter infection was well manifested--(++) according to Le Bodie et al (1987). The results allow the conclusion that one of the important pathogenetic factors of erosive gastritis, duodenitis and gastroduodenitis is the Campylobacter (Helicobacter) pylori infection of gastroduodenal mucosa.

    Objectives: We conducted an analysis of correlation between histological grading of chronic gastritis and the presence of H. pylori infection to investigate if H. pylori influences histological severity of chronic gastritis in Korean patients with peptic ulcers. Methods: Gastroscopic antral biopsy specimens and peripheral venous blood were taken from 80 patients with gastric or duodenal ulcers. H. pylori was identified microscopically in sections with Giemsa staining and quantitative grading of cultured H. pylori was reported on a scale 0 to 3. The histopathological features of biopsy specimens were reported according to the Sydney classification of chronic gastritis. Serum gastritis and pepsinogen concentrations were measured by radioimmunoassay. Results: H. pylori was identified in 62.5% (20 of 32 GU, 30 of 48 DU) of the study group. Gastric clonization rate of H. pylori did not increased with age. Forty of 50 biopsy specimens with H. pylori and also 23 of 30 biopsy specimens without H. pylori showed active chronic gastritis. There was no significant correlation overall between the presence of H. pylori and histological grading of chronic gastritis, including activity, and also no association was found between the quantitative grading of H. pylori and the histological grading of chronic gastritis. With and without H. pylori, a mean of serum gastritis concentration (79.4±43.0 pg/ml and 80.2±31.9 pg/ml) showed no significant difference, but a mean of serum pepsinogen concentration (87.7±41.6 ng/ml and 119±34.4 ng/ml) showed significant difference between the populations with and without H. pylori (p=0.001) Conclusions: The influence of H. pylori on histological grading of chronic gastritis in Korean is less than that in prior studies of Western countries, and further investigation of pathogenesis of H. pylori in chronic gastritis and peptic ulceration is necessary.

    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.

    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 (H. pylori) is the main risk factor for the development of chronic gastritis, gastric ulcer, and gastric cancer. In H. pylori-infected individuals, the clinical result is dependent on various factors, among which are bacterial components, the immune response, and environmental influence. To compare IFN-γ expression with the H. pylori vacA and cagA genotypes in patients with chronic gastritis and patients with gastric cancer. Ninety-five patients diagnosed with chronic gastritis and 20 with gastric cancer were included in the study. Three gastric biopsies were taken; one was used for the molecular detection and genotyping of H. pylori; another was fixed in absolute alcohol and histologic sections were made for determining IFN-γ expression through immunohistochemistry. No differences were found in the cells that expressed IFN-γ between the patients with chronic gastritis (median percentage of positive cells: 82.6% in patients without H. pylori and 82% in infected persons) and those with gastric cancer (70.5% in H. pylori-negative patients and 78.5% in infected persons). IFN-γ expression was 69% in chronic gastritis patients infected with H. pylori vacAs2m2/cagA⁻ it was 86.5% in patients infected with H. pylori vacAs1m2/cagA⁻, 86.5% in vacAs1m1/cagA⁻, and 82% in vacAs1m1/cagA⁺. Similar data were found in the patients with gastric cancer. IFN-γ expression varied depending on the H. pylori vacA and cagA genotype, but not in accordance with the presence of chronic gastritis or gastric cancer.

    Introduction: Ghrelin is 28-amino-acid peptide that is produced by X/A-like cells present in the stomach. Gastrin is a hormone that stimulates gastric acid secretion and mucosal cell growth. The aim: to study the interrelation between ghrelin and gastrin levels in patients with combination of chronic gastritis and type 2 diabetes mellitus. Materials and methods: 60 Helicobacter pylori positive patients with a combination of chronic gastritis and type 2 diabetes mellitus were examined. The diagnosis of type 2 diabetes mellitus is based on the recommendations of the International Diabetes Federation (IDF, 2005). Gastric acid secretion function was studied by intra-stomach express-pH-metry (method of prof. V.N. Chernobrov). Serum gastrin was determined using ELISA using Gastrin-EIA test kit Cat. No. CS 001 030. Serum ghrelin was determined by immunoassay analysis using the Human Ghrelin ELISA Kit from RayBiotech No. 1.03930005306. Results: The obtained data testify to the existence of a feedback between the level of ghrelin and gastrin in the blood of patients with chronic gastritis and type 2 diabetes mellitus. That is, with increasing levels of gastrin in the blood, the level of ghrelin in the blood decreases and vice versa with a decrease in the level of gastrin in the blood, the level of ghrelin - increases. Conclusions: A significantly higher level of ghrelin was found in patients with type 2 diabetes mellitus and chronic gastritis compared with control group. The reverse association between gastrin and ghrelin levels in patients with combination of chronic gastritis and type 2 diabetes mellitus has been obtained.

    Chronic gastritis is a common disease which forms an important background to the pathogenesis of several gastric diseases. In most instances, gastritis seems to be a bacterial (microbial) disease. It begins as long-lasting, chronic inflammatory reaction directed against Helicobacter pylori (HP), or occasionally against other spiral bacteria, which colonize in the space between the surface epithelium and the mucous layer. Gastritis may, irrespectively of the HP-related or HP-independent origin, progress to an atrophy (chronic gastritis with atrophy) in the underlying mucosa. Prevalence of gastritis increases with increase in age, but great variations exist in the age-specific prevalence and in mean age of onset of the gastritis in different populations. A high rate and an early onset of the HP-related gastritis associates with low socio-economic status. Chronic gastritis, and the gastritis with atrophy in particular, may interfere with the function of the affected gastric mucosa, and may subsequently increase or decrease the risk of some gastric diseases, such as cancer and peptic ulcer. Both antral and corpus gastritis with coexistent severe atrophic changes have been shown to be associated with an increased risk of gastric cancer. In addition, gastritis seems to also play an important role in the pathogenesis of peptic ulcer. Virtually all patients with DU and GU have coexisting and preceding gastritis. The cumulative risk of ulcer has been estimated to be high in subjects with gastritis, but, in contrast, to be low in subjects who have normal gastric mucosa.

    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.

    The recognition and removal of apoptotic inflammatory cells by tissue macrophages and non-professional phagocytes, in a process called efferocytosis, is required for resolution of inflammation and is actively anti-inflammatory. We have previously demonstrated phagocytosis of apoptotic neutrophils by tumor cells in human gastric carcinoma, but to date, there have been no studies investigating this process in chronic active Helicobacter pylori gastritis. Biopsy specimens from 28 subjects with or without H. pylori infection and active inflammation were examined and graded according to the updated Sydney system. Light microscopy, electron microscopy, and Terminal Deoxynucleotidyltransferase-Mediated UTP End Labeling staining were used to identify apoptosis. H. pylori infection was detected by histology and by molecular assay in 16 out of 28 cases. DNA from paraffin-embedded gastric biopsies was amplified using primers specific for cagA, for the cag "empty site" as well as for the s and m alleles of vacA. The more virulent cagA-positive strains were found in five out of nine patients with chronic active gastritis. The vacA s1/m1 and s2/m1 genotypes were more common in nine patients with chronic active gastritis, while the vacA s2/m2 genotype was more frequent in seven patients with chronic inactive gastritis. Apoptotic neutrophils were also detected within the cytoplasmic vacuoles of the foveolar cells of nine cases with chronic active gastritis. Transmission electron micrographs revealed further apoptotic neutrophils within spacious phagosomes of foveolar cells in a similar manner to those described in late-phase efferocytosis both in vivo and in vitro. These new observations expand the morphological spectrum of gastritis in patients infected with more virulent H. pylori strains, compatible with an anti-inflammatory role for the gastric epithelial cells in their removal of apoptotic neutrophils during active chronic gastritis.

    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.

    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. 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. 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. 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.

    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.

    Lymphocytic gastritis (LG) is an uncommon entity with varying symptoms and endoscopic appearances. This condition, as well as two forms of H. pylori-negative gastritis [chronic active gastritis (CAG) and chronic inactive gastritis (CIG)], appears to be more common in patients with coeliac disease (CD) based on single-centred studies. To compare the prevalence of LG, CAG and CIG among those with normal duodenal histology (or nonspecific duodenitis) and those with CD, as defined by villous atrophy (Marsh 3). We analysed all concurrent gastric and duodenal biopsy specimens submitted to a national pathology laboratory during a 6-year period. We performed multiple logistic regression to identify independent predictors of each gastritis subtype. Among patients who underwent concurrent gastric and duodenal biopsy (n = 287,503), the mean age was 52 and the majority (67%) were female. Compared to patients with normal duodenal histology, LG was more common in partial villous atrophy (OR: 37.66; 95% CI: 30.16-47.03), and subtotal/total villous atrophy (OR: 78.57; 95% CI: 65.37-94.44). CD was also more common in CAG (OR for partial villous atrophy 1.93; 95% CI: 1.49-2.51, OR for subtotal/total villous atrophy 2.42; 95% CI: 1.90-3.09) and was similarly associated with CIG (OR for partial villous atrophy 2.04; 95% CI: 1.76-2.35, OR for subtotal/total villous atrophy 2.96; 95% CI: 2.60-3.38). Lymphocytic gastritis is strongly associated with coeliac disease, with increasing prevalence correlating with more advanced villous atrophy. Chronic active gastritis and chronic inactive gastritis are also significantly associated with coeliac disease. Future research should measure the natural history of these conditions after treatment with a gluten-free diet. © 2015 John Wiley & Sons Ltd.

    Chronic gastritis with syndrome, functional dyspepsia (SFD) is one of the most pressing problems in medicine. Certain scientific and practical interest is the elucidation of the frequency and clinical manifestations of functional dyspepsia in patients hospitalized in the gastroenterology department YAGKB and frequency combinations of chronic gastritis (including H. pylori) with functional dyspepsia. The aim of the study was to investigate the clinical and morphological features of the chronic gastritis with syndrome pattern of functional dyspepsia in native-born and people of the Republic of Sakha (Yakutia), and to assess the effectiveness of treatment, depending on the gastric acid and H. pylori. This study examined 105 patients with functional dyspepsia, including 41 patients with epigastric pain syndrome and 64 patients with postprandial distress syndrome. Considered groups of patients were homogeneous for age, gender, by ethnicity. Of the 105 patients included in the study, I group were 57 indigenous people (80% of them--Yakutia), 11 group--48 people visiting (Caucasians). Clinical presentation and course of chronic gastritis with functional dyspepsia in the Republic of Sakha (Yakutia) have a number of distinctive features: epigastric pain syndrome occurs in 26.8% of patients and 73.2% of the indigenous population of the visitor, the intensity of pain in the root is much lower than that of visitors--12 and 85% respectively. Postprandial distress syndrome was diagnosed in 71.9% of patients and 28.1% of the indigenous newcomers. At endoscopy in all patients with functional dyspepsia diagnosed chronic gastritis. The native inhabitants of the most common mixed gastritis (54.5%), the newcomers--superficial gastritis (66.7%). The found features of a current of functional dyspepsia can be further the basis for the individualized and differentiated approaches to treatment of this disease.

  9. Autoimmune gastritis.

    Autoimmune gastritis is a chronic inflammatory disease with destruction of parietal cells of the corpus and fundus of the stomach. The known consequence is vitamin B12 deficiency and, consequently, pernicious anemia. However, loss of parietal cells reduces secretion of gastric acid which is also required for absorption of inorganic iron; thus, iron deficiency is commonly found in patients with autoimmune gastritis. This usually precedes vitamin B12 deficiency and is found mainly in young women. Patients with chronic iron deficiency, especially those refractory to oral iron therapy, should therefore be evaluated for the presence of autoimmune gastritis.

    We aimed to study MLH1 and MGMT methylation status in Helicobacter pylori-associated chronic gastritis in Egyptian patients with and without gastric cancer. 39 patients were included in our study. They were divided into 2 groups; patients without (group I) and with gastric adenocarcinoma (group II). Patients were subjected to clinical examination, abdominal ultrasound and upper endoscopy for gastric biopsy. Biopsies were subjected to urease test, histological examination, and DNA purification. H. pylori, Braf, Kras, MLH1 and MGMT methylation were assessed by quantitative PCR. DNA sequencing was performed to assess Braf and Kras genes mutation. qPCR of H. pylori was significantly higher in patients with adenocarcinoma (group II) than those without adenocarcinoma (group I); with a p < 0.001 as well as in patients with age above 50 years with a p value = 0.008. By applying logistic regression analysis it was reported that the H. pylori qPCR is a significant predictor to the adenocarcinoma with OR = 1.025 (95 % CI: 1. 002-1.048), with sensitivity of 90 % and specificity of 100 %. Adenocarcinoma patients had a significantly higher mean age and levels of H. Pylori, Braf, K-ras, methylated MGMT and methylated MLH1 than those of gastritis patients. DNA sequence analysis of Braf (codon 12) and Kras (codon 600) had genes mutation in gastric adenocarcinoma versus chronic gastritis. H. pylori may cause epigenetic changes predisposing the patients to cancer stomach. Estimation of H. pylori by qPCR can be a good predictor to adenocarcinoma. Braf and Kras genes mutation were reveled in gastritis and adenocarcinoma patients.

    AIM: To investigate the expression of different cytokeratins (CKs) in gastric epithelium of adult patients with chronic gastritis infected with Helicobacter pylori (H pylori) cagA+ strains. METHODS: The expression of CK 7, 8, 18, 19 and 20 was studied immunohistochemically in antral gastric biopsies of 84 patients. All the CKs were immunostained in cagA+H pylori gastritis (57 cases), non-H pylori gastritis (17 cases) and normal gastric mucosa (10 cases). RESULTS: In cagA+ H pylori gastritis, CK8 was expressed comparably to the normal antral mucosa from surface epithelium to deep glands. Distribution of CK18 and CK 19 was unchanged, i.e. transmucosal, but intensity of the expression was different in foveolar region in comparison to normal gastric mucosa. Cytokeratin 18 immunoreactivity was significantly higher in the foveolar epithelium of H pylori-positive gastritis compared to both H pylori-negative gastritis and controls. On the contrary, decrease in CK19 immunoreactivity occurred in foveolar epithelium of H pylori-positive gastritis. In both normal and inflamed antral mucosa without H pylori infection, CK20 was expressed strongly/moderately and homogenously in surface epithelium and upper foveolar region, but in H pylori -induced gastritis significant decrease of expression in foveolar region was noted. Generally, in both normal antral mucosa and H pylori-negative gastritis, expression of CK7 was not observed, while in about half cagA+ H pylori-infected patients, moderate focal CK7 immunoreactivity of the neck and coiled gland areas was registered, especially in areas with more severe inflammatory infiltrate. CONCLUSION: Alterations in expression of CK 7, 18, 19 and 20 together with normal expression of CK8 occur in antral mucosa of H pylori-associated chronic gastritis in adult patients infected with cagA+ strains. Alterations in different cytokeratins expression might contribute to weakening of epithelial tight junctions observed in H pylori-infected gastric

    Endothelial dysfunction is one of the early stages of vascular diseases. The aim of this study was to investigate the endothelial dysfunction markers in patients with chronic gastritis associated with Helicobacter pylori (H. pylori) infection. By a cross sectional study, basic and clinical information of 120 participants (40 patients with positive H. pylori infection, 40 patients with negative H. pylori infection and 40 healthy people) were analyzed. Carotid intima media thickness and flow-mediated dilation levels were measured in all patients and controls. Soluble vascular cell adhesion molecule-1 (sVCAM-1) and intercellular adhesion molecule-1 (ICAM-1) were measured with Elisa for all subjects. IgG level was assessed in chronic gastritis patients. The flow-mediated dilation level in patients with positive H. pylori infection (0.17%±0.09) was significantly lower than those with negative H. pylori infection (0.21% ±0.10, P<0.05) and compared to the control group (0.27% ±0.11, P<0.05). Carotid intima media thickness level in patients with positive H. pylori infection (0.58±0.13 mm) was significantly higher than those with negative H. pylori infection (0.48±0.32 mm, P<0.05) and compared to the control group (0.36±0.44mm, P<0.05). The mean level of sICAM-1 in positive H. pylori infection group (352.16±7.54 pg/mL) was higher than negative H. pylori infection group (332.64±8.75 pg/mL =0.75) and compared to the control group (236.32±12.43 pg/mL, P<0.05). A direct relationship was revealed between flow-mediated dilation and carotid intima media thickness changes and between sICAM-1 and sVCAM-1 associated with the level of H. pylori IgG in chronic gastritis. The levels of flow-mediated dilation, carotid intima media thickness and sICAM-1 were higher among patients with positive H. pylori infection. Patients with chronic gastritis associated with H. pylori infection are at risk of endothelial dysfunction due to flow-mediated dilation and carotid intima media

    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.

    In adults undergoing gastric bypass surgery, it is routine practice to perform pre-operative testing for Helicobacter pylori infection. Evidence suggests that infection impairs anastomotic healing and contributes to complications. There currently are no data for adolescents undergoing bariatric procedures. Despite few patients with pre-operative symptoms, we noted occasional patients with H. pylori detected after sleeve gastrectomy. We reviewed our experience with our adolescent sleeve gastrectomy cohort to determine the prevalence of H. pylori infection, its predictive factors, and association with outcomes. We hypothesized that H. pylori infection would be associated with pre-operative symptoms, but not surgical outcomes. All patients undergoing sleeve gastrectomy at our hospital were included. We conducted a chart review to determine pre- or post-operative symptoms of gastroesophageal reflux disease GERD or gastritis, operative complications, and long-term anti-reflux therapy after surgery. Pathology reports were reviewed for evidence of gastritis and H. pylori infection. 78 adolescents had laparoscopic sleeve gastrectomy from January 2010 through July 2014. The prevalence of chronic gastritis was 44.9% (35/78) and 11.4% of those patients had H. pylori (4/35). Only one patient with H. pylori had pre-operative symptoms, and only 25.7% (9/35) of patients with pathology-proven gastritis had symptoms. One staple line leak occurred but this patient did not have H. pylori or gastritis. Mean patient follow-up was 10 (3-26) mos. There is a moderate prevalence of gastritis among adolescents undergoing sleeve gastrectomy, but only a small number of these patients had H. pylori infection. Neither the presence of chronic gastritis nor H. pylori infection correlated with symptoms or outcomes. Thus, in the absence of predictive symptomology or adverse outcome in those who are infected, we advocate for continued routine pathologic evaluation without the required need for pre

    Histological examination of the gastric mucosa was performed in 44 patients with primary Sjögren's syndrome with extraglandular symptoms (mean age 51.9, range 22-76). Biopsy specimens were taken from each of three separate regions: the antrum, the corpus, and the transitional zone between the antrum and the corpus. The incidence of chronic atrophic gastritis was considerably higher in patients with Sjögren's syndrome than in the controls. In the young patients with Sjögren's syndrome atrophic lesions were more common both in the antrum and in the corpus than in the control group. In middle aged patients, however, only the antrum, and in the elderly only the corpus, was much more commonly affected than in the controls. All three types of chronic atrophic gastritis occurred in patients with Sjögren's syndrome. Decreased gastric acid secretion was associated mainly with atrophic gastritis of types A and AB, whereas hypergastrinaemia occurred almost exclusively in gastritis of type A. PMID:1998399

    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.

    Since technical knowledge and a high degree of experience are necessary for diagnosis of chronic gastritis, computer-aided diagnosis (CAD) systems that analyze gastric X-ray images are desirable in the field of medicine. Therefore, a new method that estimates salient regions related to chronic gastritis/non-gastritis for supporting diagnosis is presented in this paper. In order to estimate salient regions related to chronic gastritis/non-gastritis, the proposed method monitors the distance between a target image feature and Support Vector Machine (SVM)-based hyperplane for its classification. Furthermore, our method realizes removal of the influence of regions outside the stomach by using positional relationships between the stomach and other organs. Consequently, since the proposed method successfully estimates salient regions of gastric X-ray images for which chronic gastritis and non-gastritis are unknown, visual support for inexperienced clinicians becomes feasible.

    Abstract Laparoscopic sleeve gastrectomy (LSG) is a therapeutic option in severely obese patients. The aim of this study was to evaluate the presence of Helicobacter pylori (HP) gastritis and non-Helicobacter gastritis in the gastrectomy specimens, and its association to other variables. One hundred six sleeve gastrectomy specimens were examined histopathologically for the presence of gastritis and its relation to other factors like ethnicity, glycemic control, and postoperative complications. Twelve patients had HP gastritis, 39 had non-HP gastritis, and 55 had normal mucosa. There was a statistical difference between the Arab and Jewish Israeli patients in our study. Twenty-eight of the Arab patients had HP gastritis and 48% had non-HP gastritis. In the Jewish population 6% had HP gastritis and 34% had non-HP gastritis. The preoperative glycemic control was worse in the gastritis group with a mean HbA1c of 8.344% while in the normal mucosa group the mean HbA1c was 6.55. After operation the glycemic control reverted to normal in most the diabetic patients. There were few postoperative complications however, they were not related to HP. There is a high incidence of gastritis in obese patients. The incidence of gastritis in the Arab population in our study was higher than that in the Jewish population. The glycemic control before surgery was worse in patients with gastritis than in the normal mucosa group. HP bares no risk for postoperative complications after LSG and does not affect weight loss. However a larger cohort of patients must be studied to arrive at conclusive results. PMID:28422853

  1. [Chronic gastritis: Instructions for use of medications].

    PubMed

    Simanenkov, V I; Vyalov, S S

    The paper highlights the features of drug use in the legal aspect. It analyzes instructions for medical use of proton pump inhibitors (PPIs) and gastric protective agents. Taking into account the characteristics of indications registered in the instruction, the authors discuss the possibility of using various PPIs. The instruction for medical application is an official document approved by the Ministry of Health, the basis of which is the data of trials carried out by a manufacturer, and it should be a key or fundamental source for a physician in choosing a medication. The use of a drug with no indications given in the manual (the so-called 'off-label' use in foreign practice), is a clinical trial of a sort conducted by a physician individually, by taking upon himself/herself a legal liability. If arguments break out over the correct choice of this or that drug in treating the specific patient, the instruction containing the indications for use of specific medications to treat a specific disease is one of the proofs that the physician has correctly chosen the drug or a criterion for skilled medical care. The inclusion of chronic gastritis as a primary and only diagnosis into the primary documentation substantially limits the possibilities of using PPIs. When a PPI is indicated for therapy of erosive gastritis, a formal rationale is contained only in the instruction for use of Controloc. There are no registered indications for PPI use to treat chronic non-erosive gastritis; the gastric protective agent Rebagit is indicated.

    Symptoms of patients with autoimmune gastritis are not specific, and some patients may present symptoms suggestive of delayed gastric emptying. This study aims to investigate whether any delay in gastric emptying of solid food exists in patients with autoimmune gastritis and, if so, to identify the factors that might affect delayed gastric emptying. A total of 165 patients (106 women) diagnosed as having autoimmune gastritis were analyzed by means of a gastric emptying test. All patients underwent a standardized scintigraphic gastric emptying study. Patients with delayed gastric emptying and normal gastric emptying tests were then compared by means of factors that might affect gastric emptying. Also 65 patients with functional dyspepsia who had a gastric emptying study constituted the control group. The median gastric emptying T ½ time was 127.43 min (min-max 50-953) for patients with AIG and 81 min (min-max 21-121.6) for functional dyspepsia patients (p < 0.001), and median percent retention at 2 h was 63.8 versus 20.2 (p < 0.001). In multivariate analysis, parameters that affected gastric emptying T ½ time were found as serum gastrin level (OR 1.002, 95 % CI 1.001-1.004, p < 0.001, chronic inflammation (OR 3.689, 95 % CI 1.44-9.39, p < 0.001), and increase in the degree of the atrophy of the gastric mucosa (OR 8.96, 95 % CI 2.98-26.93, p < 0.001). In patients with autoimmune gastritis, gastric emptying is generally delayed. Autoimmune gastritis is an important etiology to explain the finding of delayed gastric emptying on a radionuclide test. This new finding is likely to be relevant to clinicians when evaluating and initiating appropriate medical treatment for patients with autoimmune gastritis manifesting upper gastrointestinal symptoms.

    Background Lymphocytic gastritis (LG) is an uncommon entity with varying symptoms and endoscopic appearances. This condition, as well as two forms of H. pylori-negative gastritis (chronic active gastritis [CAG] and chronic inactive gastritis [CIG]), appears to be more common in patients with coeliac disease (CD) based on single-center studies. Aim To compare the prevalence of LG, CAG, and CIG among those with normal duodenal histology (or non-specific duodenitis) and those with CD, as defined by villous atrophy (Marsh 3). Methods We analyzed all concurrent gastric and duodenal biopsy specimens submitted to a national pathology laboratory during a six-year period. We performed multiple logistic regression to identify independent predictors of each gastritis subtype. Results Among patients who underwent concurrent gastric and duodenal biopsy (n=287,503), the mean age was 52 and the majority (67%) was female. Compared to patients with normal duodenal histology, LG was more common inpartial villous atrophy (OR 37.66; 95% CI 30.16–47.03), and subtotal/total villous atrophy (OR 78.57; 95% CI 65.37–94.44). CD was also more common in CAG (OR for partial villous atrophy 1.93; 95%CI 1.49–2.51, OR for subtotal/total villous atrophy 2.42; 95%CI 1.90–3.09) and was similarly associated with CIG (OR for partial villous atrophy 2.04; 95%CI 1.76–2.35, OR for subtotal/total villous atrophy 2.96; 95% CI 2.60–3.38). Conclusion LG is strongly associated with CD, with increasing prevalence correlating with more advanced villous atrophy. CAG and CIG are also significantly associated with CD. Future researchshould measure the natural history of these conditions after treatment with a gluten-free diet. PMID:25973720

    Chronic gastritis frequently progresses into precancerous intestinal metaplasia and intraepithelial neoplasia lesions. Rebamipide is a free radical scavenger and we assessed its efficacy on clinical symptoms, gastric mucosal lesions, pathologic grade, and immunohistochemistry in chronic gastritis patients. 178 eligible patients were randomized into treatment and control groups. Both groups followed an optimized lifestyle for 26 weeks, but the treatment group was additionally medicated with rebamipide 0.1 g three times per day. Upper gastrointestinal endoscopy was performed in all patients to evaluate the severity of gastritis by the Modified Lanza Scoring (MLS) and histological changes were evaluated by the Updated Sydney System Score (USSS). Gastric mucosa immunohistochemistry in the treatment group was performed using the intestinal metaplasia markers caudal type homeobox transcription factor 2 (CDX2) and trefoil factor 3 (TFF3) detection. There were significant outcome differences between the treatment and control groups regarding the clinical symptom scores (2.62 ± 1.86 vs. 1.55 ± 1.61, P = 0.0001), gastric mucosal lesion scores (0.57 ± 1.05 vs. 0.16 ± 0.90, P = 0.002), and inflammation (P < 0.05). Only in the treated patients were the rates of intestinal metaplasia (P = 0.017 vs. P = 0.123) and low-grade intraepithelial neoplasia (P = 0.005 vs. P = 0.226) significantly reduced after 26 weeks. The percentages of CDX2 (31.5 vs. 15.7%, P = 0.021) and TFF3 (44.9 vs. 25.8%, P = 0.012) expressing gastric mucosa cells were significantly lower after rebamipide medication than pre-treatment values. Rebamipide improved the clinical symptoms, gastric mucosal lesions, and pathological grades of chronic gastritis patients and decreased the expression rates of CDX2 and TFF3 in gastric cells.

    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. © 2012 The Authors.

    Introduction The study aimed at determining the different types of precancerous conditions of the stomach and searches the frequency of Helicobacter pylori in these lesions in patients with chronic antral gastritis in Yaounde, Cameroon. Methods Five gastric biopsies were performed during upper gastrointestinal endoscopy for pathology and fixed in formol 10% before being coated in paraffin. Both the modified Giemsa and Periodic acid of Shift – Alkaline blue stains were used for the histological diagnosis of Helicobacter pylori infection. Hematoxylyn and eosin stain was used to determine the activity of gastritis, atrophic gastritis and intestinal metaplasia in accordance to the Sydney's classification of gastritis. Data were analysed using both the Epi info 6.04 and Excel 2007 softwares. Means and their standard deviations, medians and their interquartiles (IQR) were calculated. Proportions were established for qualitative variables and chi square analysis done in this study with a p value set at 0.05. Results Seventy-nine patients with chronic antral gastritis were enrolled, of which 43 (54.4%) were male, median age: 43 years (range from 21 to 70 years). The rate of atrophic gastritis was 74.7% (59/79). The activity of atrophic gastritis was mild in 47.5% (28/59) of cases, moderate in 47.5% (28/59) and severe in 5% (5/59). Intestinal metaplasia and follicular gastritis were present in 6.3% (5/79), and 10.1% (8/79), respectively. Concerning Helicobacter pylori infection, 71.2% (42/59) of patients with atrophic gastritis tested positive against 28.8% (17/59) who tested negative (p = 0.00003). Helicobacter pylori infection was related to the severity of gastric atrophy (p = 0.0001). Among patients with intestinal metaplasia and follicular gastritis, the proportion of those who tested positive for Helicobacter pylori infection was 80% (4/5), and 75% (6/8), respectively. There were no significant differences in the occurrence of atrophic gastritis according to age

    Cold Syndrome and Hot Syndrome are thousand-year-old key therapeutic concepts in traditional Chinese medicine (TCM), which depict the loss of body homeostasis. However, the scientific basis of TCM Syndrome remains unclear due to limitations of current reductionist approaches. Here, we established a network balance model to evaluate the imbalanced network underlying TCM Syndrome and find potential biomarkers. By implementing this approach and investigating a group of chronic superficial gastritis (CSG) and chronic atrophic gastritis (CAG) patients, we found that with leptin as a biomarker, Cold Syndrome patients experience low levels of energy metabolism, while the CCL2/MCP1 biomarker indicated that immune regulation is intensified in Hot Syndrome patients. Such a metabolism-immune imbalanced network is consistent during the course from CSG to CAG. This work provides a new way to understand TCM Syndrome scientifically, which in turn benefits the personalized medicine in terms of the ancient medicine and complex biological systems.

    Severity of chronic gastritis associated with Helicobacter pylori infection (CGAHpI) could play a role in evaluating the potential risk to develop gastric cancer. Our aim was to estimate the risk for gastric cancer in a clinical setting, according to histopathologic criteria, by applying the gastric cancer risk index (GCRI) METHODS: Histopathologic study of the gastric biopsies (corpus-antrum) from consecutive adult patients that underwent gastroesophageal duodenoscopy was carried out, and the GCRI was applied in patients presenting with CGAHpI. One hundred eleven patients (77% female) with a mean age of 38.6±13.1 years were included. Active Helicobacter pylori infection (aHpi) was diagnosed in 77 cases (69.40%). In 45% of the cases with aHpi, pangastritis (23%) or corpus-predominant gastritis (22%) was diagnosed. Nine cases were diagnosed with intestinal metaplasia (8%), 7 of which (77.70%) were in the aHpi group. Twenty one percent of the patients with aHpi had a GCRI of 2 (18.10%) or 3 (2.50%) points (high risk index), while 79.10% accumulated a GCRI of 0 or 1 points (low risk index). Of the patients with no aHpi, none of them had 3 points (p=0.001). Of the 18 patients that accumulated 2 or 3 points, 6 (33.30%) presented with intestinal metaplasia (all with pangastritis and corpus-predominant gastritis), of which 4 cases (66.60%) had aHpi. The estimated gastric cancer risk in patients with CGAHpI in the clinical setting studied was relatively low and 5% of the patients had a histopathologic phenotype associated with an elevated risk for developing gastric cancer.

    H. pylori gastritis and autoimmune gastritis are the two main types of chronic atrophic gastritis. Parietal cell antibody (PCA) and intrinsic factor antibody (IFA) are characteristic of autoimmune gastritis, of which IFA is more specific. Patients who are IFA negative are considered under the category of chronic atrophic gastritis. To differentiate IFA positive from IFA negative chronic atrophic gastritis. Fifty consecutive patients of biopsy proven chronic atrophic gastritis were included in this study. All patients underwent haematological and biochemical tests including serum LDH, vitamin B12 and fasting serum gastrin levels. PCA and IFA antibodies were tested in all patients. Multiple gastric biopsies from body and antrum of the stomach were taken and evaluated for presence of intestinal metaplasia, endocrine cell hyperplasia, carcinoid and H. pylori infection. Patients were grouped as group A (IFA positive) and group B (IFA negative). The mean laboratory values and histological parameters were compared between the two groups using appropriate statistical methods. Eighteen patients were in group A (mean age 55.5 +/- 13 years, male: female = 16:2) and thirty-two in group B (mean age 49.7 +/- 13 years, male: female = 25:7). There was no statistically significant difference between median values of haemoglobin, MCV, LDH, Vitamin B12 and serum gastrin in both the groups. None of the histological parameters showed any significant difference. There was no statistically significant difference in haematological, biochemical and histological parameters in IFA positive and negative gastritis. These may be the spectrum of the same disease, where H. pylori may be responsible for initiating the process.

    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.

The Virtual chromoendoscopy system allows better observation of the gastric mucosa. Evaluate the agreement between the Kimura-Takemoto ´s endoscopic system classification and the histological system of OLGA (Operative for Link Assessment Gastritis), as well as to evaluate the application of the virtual chromoendoscopy. A prospective and longitudinal study of cohorts, 138 patients was include, using endoscopic system of atrophy by Kimura and Takemoto (K-T), with conventional optical and with the use of seventh filter of virtual chromoendoscopy ,then comparing with the histological findings of the OLGA pathology system, also were determinated injuries associated with respect to stage OLGA. The kappa index of agreement between conventional endoscopy and the system OLGA was 0.859 and with the system of virtual chromoendoscopy was 0.822, the preneoplasic and neoplastic gastric lesions were associate to stages III and IV of atrophy.

    To investigate the influence of proton pump inhibitors (PPIs) exposure on the diagnosis of Helicobacter pylori (H. pylori) gastritis and intestinal metaplasia. Chronic PPI use is associated with masking of H. pylori infection. Patients with H. pylori infection are predisposed to gastric and duodenal ulcers, and long-term infection with this organism has been associated with gastric mucosal atrophy and serious long-term complications, such as gastric lymphoma and adenocarcinoma. Three hundred patients diagnosed with gastritis between January 2008 and April 2010 were included in our study. The computerized medical database of these patients was reviewed retrospectively in order to assess whether the type of gastritis diagnosed (H. pylori vs non-H. pylori gastritis) is influenced by PPI exposure. H. pylori density was graded as low, if corresponding to mild density following the Updated Sydney System, or high, if corresponding to moderate or severe densities in the Updated Sydney System. Patients were equally distributed between males and females with a median age at the time of diagnosis of 50 years old (range: 20-87). The histological types of gastritis were classified as H. pylori gastritis (n = 156, 52%) and non-H. pylori gastritis (n = 144, 48%). All patients with non-H. pylori gastritis had inactive chronic gastritis. Patients with no previous PPI exposure were more likely to be diagnosed with H. pylori gastritis than those with previous PPI exposure (71% vs 34.2%, P < 0.001). Intestinal metaplasia was more likely to be detected in the latter patients (1.4% vs 6.5%, P = 0.023). Multivariate analysis has also demonstrated that in the presence of previous PPI exposure (OR = 0.217, 95%CI: 0.123-0.385), GERD (OR = 0.317, 95%CI: 0.132-0.763, P = 0.01), alcohol intake (OR = 0.396, 95%CI: 0.195-0.804, P = 0.01), the detection of H. pylori was less likely. Chronic use of PPIs may mask H. pylori infections promoting the diagnosis of non-H. pylori gastritis and leads to a

    To assess the clinical effects and safety of Huangqi Jianzhong Tang (HQJZ) for the treatment of chronic gastritis (CG), three English databases and four Chinese databases were searched through the inception to January 2015. In randomized controlled trials (RCTs) comparing HQJZ with placebo, no intervention and western medicine were included. A total of 9 RCTs involving 979 participants were identified. The methodological quality of the included trials was generally poor. Meta-analyses demonstrated that HQJZ plus conventional medicine was more effective in improving overall gastroscopy outcome than western medicine alone for treatment of chronic superficial gastritis with the pooling result of overall improvement [OR 3.78 (1.29,11.06), P = 0.02]. In addition, the combination of HQJZ with antibiotics has higher overall effect rate than antibiotics alone for the treatment of CG [OR 2.60 (1.49,4.54), P = 0.0007]. There were no serious adverse events reported in both the intervention and controlled groups. HQJZ has the potential of improvement of the patients' gastroscopy outcomes, Helicobacter pylori clearance rate, traditional Chinese Medicine syndromes, and overall effect rate alone or in combination use with conventional western medicine for chronic atrophic gastritis. However, due to poor methodological quality, the beneficial effect and safeties of HQJZ for CG could not be confirmed. PMID:26819622

    Virulent genotypes of Helicobacter pylori vacA s1m1/cagA + /babA2 + have been associated with severe gastric diseases. VacA, CagA and BabA are polymorphic proteins, and their association with the disease is allele-dependent. The aims of this work were: (i) to determine the prevalence of H. pylori by type of chronic gastritis; (ii) to describe the frequency of cagA, babA2 and vacA genotypes in strains from patients with different types of chronic gastritis; (iii) to characterize the variable region of cagA alleles. A total of 164 patients with chronic gastritis were studied. Altogether, 50 H. pylori strains were isolated, and the status of cagA, babA2 and vacA genotypes was examined by PCR. cagA EPIYA segment identification was performed using PCR and sequencing of cagA fragments of six randomly selected strains.Results/Key findings. The overall prevalence of H. pylori was 30.5 %. Eighty percent of the isolated strains were vacA s1m1, and the cagA and babA2 genes were detected in 74 and 32 % of the strains, respectively. The most frequent genotypes were vacA s1m1/cagA + /babA2 - and vacA s1m1/cagA + /babA2 + , with 40 % (20/50) and 28 % (14/50), respectively. In cagA + , the most frequent EPIYA motif was -ABC (78.4 %), and EPIYA-ABCC and -ABCCC motifs were found in 10.8 % of the strains. A modified EPIYT-B motif was found in 66.6 % of the sequenced strains. H. pylori strains carrying vacA s1m1, cagA + and babA2 - genotypes were the most prevalent in patients with chronic gastritis from the south of Mexico. In the cagA + strains, the EPIYA-ABC motif was the most common.

    Purpose Virulent genotypes of Helicobacter pylori vacA s1m1/cagA+/babA2+ have been associated with severe gastric diseases. VacA, CagA and BabA are polymorphic proteins, and their association with the disease is allele-dependent. The aims of this work were: (i) to determine the prevalence of H. pylori by type of chronic gastritis; (ii) to describe the frequency of cagA, babA2 and vacA genotypes in strains from patients with different types of chronic gastritis; (iii) to characterize the variable region of cagA alleles. Methodology A total of 164 patients with chronic gastritis were studied. Altogether, 50 H. pylori strains were isolated, and the status of cagA, babA2 and vacA genotypes was examined by PCR. cagA EPIYA segment identification was performed using PCR and sequencing of cagA fragments of six randomly selected strains. Results/Key findings The overall prevalence of H. pylori was 30.5 %. Eighty percent of the isolated strains were vacA s1m1, and the cagA and babA2 genes were detected in 74 and 32 % of the strains, respectively. The most frequent genotypes were vacA s1m1/cagA+/babA2- and vacA s1m1/cagA+/babA2+, with 40 % (20/50) and 28 % (14/50), respectively. In cagA+, the most frequent EPIYA motif was -ABC (78.4 %), and EPIYA-ABCC and -ABCCC motifs were found in 10.8 % of the strains. A modified EPIYT-B motif was found in 66.6 % of the sequenced strains. Conclusion H. pylori strains carrying vacA s1m1, cagA+ and babA2- genotypes were the most prevalent in patients with chronic gastritis from the south of Mexico. In the cagA+ strains, the EPIYA-ABC motif was the most common. PMID:29458667

    The aims of this study were to evaluate the clinicopathologic features of Helicobacter heilmannii-associated gastritis and to compare H. heilmannii-associated gastritis with H. pylori-associated gastritis. We reviewed 5,985 consecutive gastric biopsy specimens. All cases of chronic gastritis with Helicobacter infection were evaluated with the Updated Sydney System, and the grades of all gastritis variables were compared between H. heilmannii-associated gastritis and H. pylori-associated gastritis groups. There were 10 cases of H. heilmannii-associated gastritis (0.17%) and 3,285 cases of H. pylori-associated gastritis (54.9%). The organisms were superficially located within the mucous layer without adhesion to epithelial cells. Interestingly, in one case many intracytoplasmic H. heilmannii organisms were observed in parietal cells with cell damage. A case of low-grade mucosa-associated lymphoid tissue (MALT) lymphoma concomitant with H. heilmannii infection was detected. Compared to H. pylori-associated gastritis, H. heilmannii-associated gastritis showed less severe neutrophilic activity (p<0.0001), mononuclear cell infiltration (p=0.0029), and endoscopic findings of chronic gastritis devoid of erosion or ulcer (p=0.0309). In conclusion, we present the detailed clinicopathologic findings of H. heilmannii-associated gastritis compared to H. pylori-associated gastritis. H. heilmannii-associated gastritis is uncommon and milder than H. pylori-associated gastritis, however it may be noteworthy with respect to the development of MALT lymphoma. PMID:17297253

    AIMS: To determine the histopathological types of gastritis, presence of H pylori, and of peptic ulceration in patients aged 70 and over, compared with younger adults. METHODS: Gastric antral and corpus biopsy specimens from 112 elderly patients were classified and graded histologically according to the Sydney system. Details of recent antibiotic and non-steroidal anti-inflammatory drug use were recorded. Eighty four of the patients were positive for H pylori IgG antibodies and parietal cell antibodies. The results were compared with those from a series of 124 adult patients aged under 60. RESULTS: H pylori were visible at histological examination in only 57 of 87 (65.5%) elderly patients with chronic gastritis (excluding "special forms") compared with 72 of 79 (91.1%) of the younger patients with gastritis (p < 0.0002). Severe atrophy of the corpus mucosa was significantly associated with absence of H pylori (p < 0.002), and was present in eight of 30 elderly patients with helicobacter negative gastritis. Other explanations for absence of H pylori include recent antibiotic intake, more intestinal metaplasia, and lower bacterial load in elderly patients (p < 0.05). Autoimmune gastritis and NSAID use did not seem to be relevant. Serodiagnosis showed reduced sensitivity (81%) in patients who were helicobacter positive histologically, but was positive in 14 of 23 (61%) with H pylori negative gastritis histologically, suggesting either current infection that had been missed or previous infection. Peptic ulceration was significantly associated with NSAID use, but not with H pylori in the elderly. CONCLUSIONS: The spectrum of gastritis is different in the elderly, compared with younger adults, due to a significant group with chronic gastritis who are H pylori negative on histological examination. NSAID use, but not demonstration of H pylori (at histological examination) is associated with peptic ulceration in the elderly. PMID:1479032

    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.

    Purpose The prevalence of Helicobacter pylori gastritis has been declining, whereas H. pylori-negative gastritis has become more common. We evaluated chronic gastritis in children with regard to H. pylori status and celiac disease (CD). Patients and methods Demographic, clinical, endoscopic, and histologic features of children who underwent elective esophagogastroduodenoscopy were reviewed retrospectively. Gastric biopsies from the antrum and corpus of the stomach were graded using the Updated Sydney System. H. pylori presence was defined by hematoxylin and eosin, Giemsa, or immunohistochemical staining and urease testing. Results A total of 184 children (61.9% female) met the study criteria with a mean age of 10 years. A total of 122 (66.3%) patients had chronic gastritis; 74 (60.7%) were H. pylori-negative. Children with H. pylori-negative gastritis were younger (p=0.003), were less likely to present with abdominal pain (p=0.02), and were mostly of non-Arabic origin (p=0.011). Nodular gastritis was found to be less prevalent in H. pylori-negative gastritis (6.8%) compared with H. pylori-positive gastritis (35.4%, p<0.001). The grade of mononuclear infiltrates and neutrophil density was more severe in the H. pylori-positive group (p<0.001). Pan-gastritis and lymphoid follicles were associated most commonly with H. pylori. Although less typical, lymphoid follicles were demonstrated in 51.3% of H. pylori-negative patients. The presence or absence of CD was not associated with histologic findings in H. pylori-negative gastritis. Conclusion Our findings suggest that lymphoid follicles are a feature of H. pylori-negative gastritis in children independent of their CD status. PMID:28860835

    AIM: To investigate the influence of proton pump inhibitors (PPIs) exposure on the diagnosis of Helicobacter pylori (H. pylori) gastritis and intestinal metaplasia. METHODS: Chronic PPI use is associated with masking of H. pylori infection. Patients with H. pylori infection are predisposed to gastric and duodenal ulcers, and long-term infection with this organism has been associated with gastric mucosal atrophy and serious long-term complications, such as gastric lymphoma and adenocarcinoma. Three hundred patients diagnosed with gastritis between January 2008 and April 2010 were included in our study. The computerized medical database of these patients was reviewed retrospectively in order to assess whether the type of gastritis diagnosed (H. pylori vs non-H. pylori gastritis) is influenced by PPI exposure. H. pylori density was graded as low, if corresponding to mild density following the Updated Sydney System, or high, if corresponding to moderate or severe densities in the Updated Sydney System. RESULTS: Patients were equally distributed between males and females with a median age at the time of diagnosis of 50 years old (range: 20-87). The histological types of gastritis were classified as H. pylori gastritis (n = 156, 52%) and non-H. pylori gastritis (n = 144, 48%). All patients with non-H. pylori gastritis had inactive chronic gastritis. Patients with no previous PPI exposure were more likely to be diagnosed with H. pylori gastritis than those with previous PPI exposure (71% vs 34.2%, P < 0.001). Intestinal metaplasia was more likely to be detected in the latter patients (1.4% vs 6.5%, P = 0.023). Multivariate analysis has also demonstrated that in the presence of previous PPI exposure (OR = 0.217, 95%CI: 0.123-0.385), GERD (OR = 0.317, 95%CI: 0.132-0.763, P = 0.01), alcohol intake (OR = 0.396, 95%CI: 0.195-0.804, P = 0.01), the detection of H. pylori was less likely. Chronic use of PPIs may mask H. pylori infections promoting the diagnosis of non-H. pylori

    AIM: To investigate the occurrence of chromosome 3, 7, 8, 9, and 17 aneuploidies, TP53 gene deletion and p53 protein expression in chronic gastritis, atrophic gastritis and gastric ulcer, and their association with H pylori infection. METHODS: Gastric biopsies from normal mucosa (NM, n = 10), chronic gastritis (CG, n = 38), atrophic gastritis (CAG, n=13) and gastric ulcer (GU, n = 21) were studied using fluorescence in situ hybridization (FISH) and immunohistochemical assay. A modified Giemsa staining technique and PCR were used to detect H pylori. An association of the gastric pathologies and aneuploidies with H pylori infection was assessed. RESULTS: Aneuploidies were increasingly found from CG (21%) to CAG (31%) and to GU (62%), involving mainly monosomy and trisomy 7, trisomies 7 and 8, and trisomies 7, 8 and 17, respectively. A significant association was found between H pylori infection and aneuploidies in CAG (P = 0.0143) and GU (P = 0.0498). No TP53 deletion was found in these gastric lesions, but p53-positive immunoreactivity was detected in 45% (5/11) and 12% (2/17) of CG and GU cases, respectively. However, there was no significant association between p53 expression and H pylori infection. CONCLUSION: The occurrence of aneuploidies in benign lesions evidences chromosomal instability in early stages of gastric carcinogenesis associated with H pylori infection, which may confer proliferative advantage. The increase of p53 protein expression in CG and GU may be due to overproduction of the wild-type protein related to an inflammatory response in mucosa. PMID:16489680

    To investigate the effectiveness of 10-day bismuth-containing quadruple (B-quadruple) treatment as first-line therapy in patients with Helicobacter pylori-related chronic gastritis. A randomized controlled trial was conducted from October 2011 to December 2013 in Zhejiang, China, including patients with H. pylori-related chronic gastritis who were randomly provided either 10-day omeprazole-based triple therapy (OM-triple; omeprazole 20 mg twice daily, clarithromycin 500 mg twice daily and amoxicillin 1 g twice daily) or 10-day B-quadruple therapy (OM-triple + bismuth subcitrate 120 mg four times daily). H. pylori status, pathologic findings and dyspeptic symptoms were assessed at baseline and after 3 months. The primary outcome was H. pylori eradication rates by intention-to-treat (ITT) and per-protocol (PP) analyses. The secondary outcomes were the histologic and symptomatic benefits from H. pylori eradication. A total of 351 patients with H. pylori-related chronic gastritis were recruited. The eradication rates of the OM-triple and B-quadruple groups were 58.4% (108/185) and 86.1% (143/166) respectively according to ITT analysis (p <0.01). PP rates of H. pylori eradication were 63.2% (108/171) and 92.3% (143/155) respectively (p <0.01). According to the PP analysis, active and chronic inflammation in gastric mucosa was substantially improved in all treated patients (n=326). However, pathologic atrophic gastritis and intestinal metaplasia did not regress in both groups (n=326). The reduction of dyspeptic symptoms score was significantly higher in the B-quadruple group than in the OM-triple group (0.59±0.057 vs. 0.39±0.046) (p <0.01). Ten-day B-quadruple therapy is more effective than OM-triple therapy as first-line therapy for patients with H. pylori-induced chronic gastritis in China. Copyright © 2017 The Authors.

    To investigate the potential therapeutic effect of exopolysaccharide (EPS)-producing Streptococcus thermophilus (S. thermophilus) CRL 1190 fermented milk on chronic gastritis in Balb/c mice. Balb/c mice were fed with the fermented milk for 7 d after inducing gastritis with acetyl-salicylic acid (ASA, 400 mg/kg body weight per day for 10 d). Omeprazole was included in this study as a positive therapeutic control. The gastric inflammatory activity was evaluated from gastric histology and inflammation score, number of interleukin-10 (IL-10), interferon-gamma (INFgamma) and tumor necrosis factor-alpha (TNF-alpha) cytokine-producing cells in the gastric mucosa, and thickness of the mucus layer. Animals receiving treatment with the EPS-producing S. thermophilus CRL 1190 fermented milk showed a conserved gastric mucosa structure similar to that of healthy animals. Inflammation scores of the fermented milk-treated mice were lower than those of mice in the gastritis group (0.2 + or - 0.03 vs 2.0 + or - 0.6, P < 0.05). A marked decrease in INFgamma(+) (15 + or - 1.0 vs 28 + or - 1.2, P < 0.05) and TNF-alpha(+) (16 + or - 3.0 vs 33 + or - 3.0, P < 0.05) cells and an increase in IL-10(+) (28 + or - 1.5 vs 14 + or - 1.3, P < 0.05) cells compared to the gastritis group, was observed. Also, an increase in the thickness of the mucus gel layer (2.2 + or - 0.6 vs 1.0 + or - 0.3; 5.1 + or - 0.8 vs 1.5 + or - 0.4 in the corpus and antrum mucosa, respectively, P < 0.05) compared with the gastritis group was noted. A milk suspension of the purified EPS from S. thermophilus CRL1190 was also effective as therapy for gastritis. This study suggests that fermented milk with S. thermophilus CRL 1190 and/or its EPS could be used in novel functional foods as an alternative natural therapy for chronic gastritis induced by ASA.

    Helicobacter pylori adheres to various components of the human saliva. Therefore, the objective of this research was to simultaneously detect H. pylori in saliva and in gastric biopsy, and to determine the agreement between the vacA genotypes in both saliva and gastric biopsy. A total of 162 patients with chronic gastritis and 34 with gastric ulcer were studied, and saliva and biopsy samples were collected from each patient. H. pylori DNA was detected by conventional PCR and nested PCR was used for vacA genotyping. In 24% of the patients (47/196) H. pylori DNA was found in saliva and in biopsy; 52.5% (103/196) were saliva(negative)/biopsy(positive) and 6.6% (13/196) were saliva(positive)/biopsy(negative). In either or both H. pylori vacAs1m1 or s1m2 genotypes were detected in saliva in 41.5% of the patients with chronic gastritis. Forty-seven percent had >1 genotype, and the s1m1/s1m2 combination was found in 36% of them. H. pylori vacAs1m1 and s1m2 were also found in the saliva and biopsy of patients with gastric ulcer. The genotypes found in saliva and biopsy of the same patient had 51.1% agreement. In 27.6% of the 47 patients saliva(positive)/biopsy(positive) two genotypes were found in saliva, and one or both in the stomach. The s1m1/s1m2 genotypes, alone or together, are found simultaneously in saliva and gastric biopsy of the same patient. These results suggest that H. pylori reaches the oral cavity by various ways, and that saliva can be the transmitting and re-infecting vector. Copyright © 2012 Elsevier España, S.L.

    Gastritis is an important premalignant lesion and recent studies suggested a production of inflammatory cytokine-like C-reactive protein during gastritis. This study aimed to determine any relationship between high sensitive C-reactive protein (hs-CRP) and inflammation activity among patients with gastritis. Demographic and clinical variables of participants were collected by a validated questionnaire. Using histology of the gastric mucosa, Helicobacter pylori status was investigated and serum concentrations of hs-CRP were measured among dyspeptic patients. Correlation between hs-CRP serum levels and inflammation activities was evaluated by logistic regression analysis. The relation between active inflammation and other variables was evaluated by logic link function model. Totally 239 patients (56.6% female) were analysed. The prevalence of mild, moderate and severe inflammation activities was 66.5%, 23.8% and 9.6% respectively. Mean ± SD of hs-CRP among men and women were 2.85 ± 2.84 mg/dl and 2.80 ± 4.80 mg/dl (p = 0.047) respectively. Mean ± SD of hs-CRP among patients with H. pylori infection, gland atrophy, metaplasia and dysplasia were 2.83 ± 3.80 mg/dl, 3.52 ± 5.1 mg/dl, 2.22 ± 2.3 mg/dl and 5.3 ± 5.04 mg/dl respectively. Relationship between hs-CRP and inflammation activities (p < 0.01) was significant. A significant relationship between dysplasia and hs-CRP (p < 0.04) was revealed. A significant relationship between age and hs-CRP was detected (p < 0.05). Although serum hs-CRP is not a specific biomarker for gastritis, elevated hs-CRP levels may be considered as a predictive marker of changes in gastric mucosa and a promising therapeutic target for patients with gastritis.

    The endoscopic diagnosis of chronic atrophic gastritis is often underestimated, and most of the procedures adopted to increase diagnostic accuracy are time consuming and complex. In this study, we evaluated the usefulness of the determination of gastric juice pH by means of litmus paper. Values obtained by this method correlate well with gastric acid secretory capacity as measured by gastric acid analysis (r = -0.64, p less than 0.001) and are not affected by the presence of bile. Gastric juice pH determination increases sensitivity and other diagnostic parameters such as performance index (Youden J test), positive predictive value, and post-test probability difference by 50%. Furthermore, the negative predictive value is very high, the probability of missing a patient with chronic atrophic gastritis with this simple method being 2% for fundic and 15% for antral atrophic change. We conclude that gastric juice pH determination, which substantially increases diagnostic accuracy and is very simple to perform, should be routinely adopted.

    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.

    Although many gastric cancers arise in chronic gastritis, the association between adenocarcinoma of the esophagogastric junction and the status of background gastritis remains unclear. We aim to investigate the histological status of gastritis in the background fundic gland mucosa of adenocarcinoma of the esophagogastric junction. The present study included 121 consecutive patients with superficial adenocarcinoma of the esophagogastric junction obtained by surgical and/or endoscopic resection. We re-evaluated the histogenesis of adenocarcinoma of the esophagogastric junction, including the background fundic gland mucosa using the Updated Sydney System. The prevalence of histologic atrophic gastric mucosa with gastritis (positive gastritis), non-atrophic gastric mucosa without gastritis (negative gastritis) and Barrett's adenocarcinoma was examined. Histologic-positive gastritis was found in 67 (55%) of all patients, in 24 (38%) of 63 Barrett's adenocarcinoma patients and in 43 (74%) of 58 non-Barrett's adenocarcinoma patients (P < 0.01). A higher female ratio in non-Barrett's adenocarcinoma with gastritis patients `and younger age in non-Barrett's adenocarcinoma without gastritis patients were shown. There were no differences in clinicopathological features related to the gastritis status in Barrett's adenocarcinoma patients. Reflux esophagitis was observed in most (81%) of all patients, and 32 (74%) of the non-Barrett's adenocarcinoma with gastritis patients. In the 67 positive gastritis patients, the mean Updated Sydney System scores of glandular atrophy and intestinal metaplasia were 1.45 and 1.10, respectively, and these scores were higher in the non-Barrett's adenocarcinoma patients than in the Barrett's adenocarcinoma patients. This study suggests that about half of the patients with adenocarcinoma of the esophagogastric junction harbor histological gastritis. Adenocarcinoma of the esophagogastric junction is considered to be a heterogeneous entity, including

    Laparoscopic sleeve gastrectomy (LSG) is a therapeutic option in severely obese patients. The aim of this study was to evaluate the presence of Helicobacter pylori (HP) gastritis and non-Helicobacter gastritis in the gastrectomy specimens, and its association to other variables.One hundred six sleeve gastrectomy specimens were examined histopathologically for the presence of gastritis and its relation to other factors like ethnicity, glycemic control, and postoperative complications.Twelve patients had HP gastritis, 39 had non-HP gastritis, and 55 had normal mucosa. There was a statistical difference between the Arab and Jewish Israeli patients in our study. Twenty-eight of the Arab patients had HP gastritis and 48% had non-HP gastritis. In the Jewish population 6% had HP gastritis and 34% had non-HP gastritis. The preoperative glycemic control was worse in the gastritis group with a mean HbA1c of 8.344% while in the normal mucosa group the mean HbA1c was 6.55. After operation the glycemic control reverted to normal in most the diabetic patients. There were few postoperative complications however, they were not related to HP.There is a high incidence of gastritis in obese patients. The incidence of gastritis in the Arab population in our study was higher than that in the Jewish population. The glycemic control before surgery was worse in patients with gastritis than in the normal mucosa group. HP bares no risk for postoperative complications after LSG and does not affect weight loss. However a larger cohort of patients must be studied to arrive at conclusive results.

    Gastric infection with Helicobacter pylori (Hp) can lead to chronic inactive gastritis, atrophy and intestinal metaplasia. To investigate in a cross-sectional study these changes among different socioeconomic and ethnic groups within the USA. We used the Miraca Life Sciences database, an electronic depository of clinicopathological records from patients distributed throughout the USA, to extract data from 487 587 patients who underwent oesophago-gastro-duodenoscopy with biopsy between 1/2008 and 12/2014. We then classified patients into ethnic and socioeconomic categories using previously validated algorithms, as well as ZIP code-based information derived from the 2011-2012 US Census. The prevalence of Hp increased significantly until the age-group 40-49, before it leveled off and started a gradual decrease. The prevalence of chronic inactive gastritis, atrophy, and intestinal metaplasia increased significantly with age. The prevalence of Hp, chronic inactive gastritis, intestinal metaplasia, and atrophy decreased significantly with the percentage of Whites per ZIP code. The prevalence of all four diagnoses also decreased significantly with rising levels of income or college education. Hp, chronic inactive gastritis, atrophy and intestinal metaplasia were more common among Hispanics and the influence of income or college education less pronounced than in the entire population. Hp, chronic inactive gastritis, atrophy, and intestinal metaplasia were also more common among East-Asians, Hp and atrophy decreasing with rising income but remaining unaffected by levels of college education. Ethnicity and socioeconomic factors influence the occurrence of Hp gastritis, and its progression to chronic inactive gastritis, atrophy or intestinal metaplasia. © 2017 John Wiley & Sons Ltd.

    To explore the correlation between serum vitamin B12 level and peripheral neuropathy in patients with chronic atrophic gastritis (CAG). A total of 593 patients diagnosed with chronic gastritis by gastroscopy and pathological examination from September 2013 to September 2016 were selected for this study. The age of these patients ranged within 18- to 75-years-old. Blood pressure, height and weight were measured in each patient, and the body mass index value was calculated. Furthermore, gastric acid, serum gastrin, serum vitamin and serum creatinine tests were performed, and peripheral nerve conduction velocity and Helicobacter pylori ( H. pylori ) were detected. In addition, the type of gastritis was determined by gastroscopy. The above factors were used as independent variables to analyze chronic gastritis with peripheral neuropathy and vitamin B12 deficiency risk factors, and to analyze the relationship between vitamin B12 levels and peripheral nerve conduction velocity. In addition, in the treatment of CAG on the basis of vitamin B12, patients with peripheral neuropathy were observed. Age, H. pylori infection, CAG, vitamin B9 and vitamin B12 were risk factors for the occurrence of peripheral nerve degeneration. Furthermore, CAG and H. pylori infection were risk factors for chronic gastritis associated with vitamin B12 deficiency. Serum vitamin B12 level was positively correlated with sensory nerve conduction velocity in the tibial nerve ( R = 0.463). After vitamin B12 supplementation, patients with peripheral neuropathy improved. Serum vitamin B12 levels in patients with chronic gastritis significantly decreased, and the occurrence of peripheral neuropathy had a certain correlation. CAG and H. pylori infection are risk factors for vitamin B12 deficiency and peripheral neuropathy. When treating CAG, vitamin B12 supplementation can significantly reduce peripheral nervous system lesions. Therefore, the occurrence of peripheral neuropathy associated with vitamin B12

    2011-01-01

    Background The aim of this study is evaluating the correlation of postprandial fullness with chronic gastritis or rapid inflow of gastric content into duodenum, based on double-contrast barium X-ray imaging. Methods 253 healthy subjects who underwent upper gastrointestinal barium X-ray examination were analyzed. Chronic gastritis was judged from mucosal atrophy and hypertrophic thickened folds on barium X-ray images. For the gastric excretion, the tips of barium flow on the single-contrast frontal barium X-ray images of the stomach were classified into four categories; V type (all the barium remained in the stomach), V-H type (some barium had flowed into the duodenum but the tip of barium remained in the proximal half of the duodenal bulb), H-V type (some barium had flowed into the duodenum and the tip of barium was in the distal half of duodenal the bulb, but no barium was observed in the descending part of the duodenum), and H type (some barium had flowed into the descending part of the duodenum). The chi-square test and Cochran-Mantel-Haenzel test were used for evaluation. Results Chronic gastritis was observed in 72 subjects, among which 21 subjects (29.2%) presented with postprandial fullness. For the remaining 181 subjects without chronic gastritis, 53 subjects (29.3%) complained of postprandial fullness. There is no significant correlation between chronic gastritis and postprandial fullness (p = 0.973). For the rapid flow of gastric content into duodenum, all the 253 subjects comprised 136 subjects with V type (in the stomach), 40 subjects with V-H type (in the proximal half of the duodenal bulb), 21 subjects with H-V type (in the distal half of the duodenal bulb), and 56 subjects with H type (in the descending part of the duodenum). Postprandial fullness was present in 30 subjects with V type (22.1%), 9 subjects with V-H type (22.5%), 8 subjects with H-V type (38.1%), and 27 subjects with H type (48.2%).

    Background Helicobacter pylori has been strongly associated with chronic gastritis, peptic and duodenal ulcers, and it is a risk factor for gastric cancer. Three major virulence factors of H. pylori have been described: the vacuolating toxin (VacA), the cytotoxin-associated gene product (CagA) and the adhesion protein BabA2. Since considerable geographic diversity in the prevalence of H. pylori virulence factors has been reported, the aim of this work was to establish the H. pylori and vacA, cagA and babA2 gene status in 238 adult patients, from a marginal urban area of Mexico, with chronic gastritis. Methods H. pylori was identified in cultures of gastric biopsies by nested PCR. vacA and cagA genes were detected by multiplex PCR, whereas babA2 gene was identified by conventional PCR. Results H. pylori-positive biopsies were 143 (60.1%). All H. pylori strains were vacA+; 39.2% were cagA+; 13.3% were cagA+ babA2+ and 8.4% were babA2+. Mexican strains examined possessed the vacA s1, m1 (43.4%), s1, m2 (24.5%), s2, m1 (20.3%) and s2, m2 (11.9%) genotypes. Conclusion These results show that the Mexican patients suffering chronic gastritis we have studied had a high incidence of infection by H. pylori. Forty four percent (63/143) of the H. pylori strains analyzed in this work may be considered as highly virulent since they possessed two or three of the virulence markers analyzed: vacA s1 cagA babA2 (9.8%, 14/143), vacA s1 babA2 (4.9%, 7/143), and vacA s1 cagA (29.4%, 42/143). However, a statistically significant correlation was not observed between vacAs1, cagA and babA2 virulence markers (χ2 test; P > 0.05). PMID:19405980

    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. 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. 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. 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.

    Helicobacter pylori (H. pylori) gastric infection is a main cause of inflammatory changes and gastric cancers. The aim of this study was finding the effects of curcumin on oxidative stress and histological changes in chronic gastritis associated with H. pylori. In a randomized clinical trial, patients were divided into two groups: a standard triple therapy group and triple therapy with curcumin group. Endoscopic and histological examinations were measured for all patients before and after 8 weeks. Triple therapy with curcumin treatment group significantly decreased malondialdehyde markers, glutathione peroxides and increased total antioxidant capacity of the gastric mucosa at the end of study compared to baseline and triple regimen groups. In addition, the oxidative damage to DNA was significantly decreased in triple therapy with curcumin group at the end of study compared to baseline and compared to triple therapy (P<0.05 for both). Triple therapy group in combination with Curcumin significantly decreased all active, chronic and endoscopic inflammation scores of patients compared to the baseline and triple therapy group (P<0.05 for both). The eradication rate by triple therapy + curcumin was significantly increased compared to triple therapy alone (P<0.05). Curcumin can be a useful supplement to improve chronic inflammation and prevention of carcinogenic changes in patients with chronic gastritis associated by H. pylori.

    To observe the effects and safety of quadruple regimens including domestically manufactured rabeprazole used as first line/initial therapy for Helicobacter pylori(H.pylori) eradication in gastritis and duodenal ulcer patients, and to investigate the effects of extended use of bismuth after the quadruple therapy on eradication of H. pylori. From January to August 2013, 430 patients with chronic gastritis or duodenal ulcer who were confirmed as H. pylori positive in gastroscopy for upper gastrointestinal symptoms were enrolled from 12 centers in China for initial treatment using quadruple regimens for H. pylori eradication. The study was a prospective, multicenter, randomized double-blinded double-dummy parallel-controlled clinical trial. The 310 chronic gastritis patients were divided into 2 groups: group A1 was given quadruple regime (rabeprazole+ amoxicillin+ clarithromycin+ bismuth potassium citrate) for 10 days followed by bismuth-placebo for 21 days; group A2 was given the quadruple regimen for 10 days and then bismuth potassium citrate for 21 days. The duodenal ulcer patients were given the quadruple for 10 days, then rabeprazole for 14 days. All the patients took (13)C urea breath test to detect H. pylori 28 days after medicine withdrawal. Altogether 428 cases were enrolled and 404 completed the trial. The total eradication rate in the chronic gastritis patients was 85.1% (262/308, intention-to-treat (ITT)analysis), which was 81.7% (125/153, ITT) in the A1 group and 88.4% (137/155, ITT) in the A2 group; the eradication rate in the duodenal ulcer patients was 85.8% (103/120, ITT). No severe adverse effects were reported. The symptoms (pain, burning sensation, reflux, belching, nausea, and vomiting) improvement status was similar among A1 and A2 groups. The quadruple regimen using rabeprazole manufactured in China and administered for 10 days as first line/initial therapy in chronic gastritis and duodenal ulcer patients could achieve good H. pylori eradication

    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.

    The main pathogenesis of gastritis is inflammation that closely related to free radicals. Malondialdehyde (MDA) is a free radical biomarker and is found to increase in gastritis patients. However, these studies are generally performed on experimental animals as well as MDA examination in gastric mucosa. This study aim was to determine the association of degrees of gastritis (degree of lymphocyte infiltration, neutrophil activity, atrophy, and intestinal metaplasia) with plasma MDA level. A cross-sectional study of 80 consecutive gastritis patients who came to an endoscopic unit of Adam Malik General Hospital in Medan, Indonesia, from May–September 2017. Assessed for severity of chronic inflammatory, neutrophil activity, atrophy, and intestinal metaplasia refers to Updated Sydney System. Plasma MDA levels were examined using an HPLC MDA kit. Univariate analysis, bivariate (chi-square and Fisher exact test), and multivariate (binary logistic regression test) were programmed with SPSS version 22. There was no significant association between degree of lymphocyte infiltration with MDA level. There were significant associations between degree of neutrophil activity, atrophy, and intestinal metaplasia with MDA level (p=0.039, 0.003, 0.021; respectively). The moderate+severe degree of neutrophil activity, atrophy, and intestinal metaplasia were associated with high level of MDA.

    In Traditional Chinese Medicine (TCM), most of the algorithms used to solve problems of syndrome diagnosis are superficial structure algorithms and not considering the cognitive perspective from the brain. However, in clinical practice, there is complex and nonlinear relationship between symptoms (signs) and syndrome. So we employed deep leaning and multilabel learning to construct the syndrome diagnostic model for chronic gastritis (CG) in TCM. The results showed that deep learning could improve the accuracy of syndrome recognition. Moreover, the studies will provide a reference for constructing syndrome diagnostic models and guide clinical practice.

    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.

    Chromogranin A is an important tool in the diagnosis of neuroendocrine tumors. Autoimmune gastritis is an autoimmune disorder marked by hypergastrinemia, which stimulates enterochromaffin-like cell proliferation. Chromogranin A is also elevated in autoimmune gastritis patients with a different level of increase in each patient. The goal of this study is to explore constituents that influence serum chromogranin A levels in autoimmune gastritis patients. One hundred and eighty-eight autoimmune gastritis patients and 20 patients with type I gastric carcinoid tumors were analyzed retrospectively and compared to 110 functional dyspepsia patients in terms of factors that might affect serum chromogranin A levels. The mean serum chromogranin A level was 171.17±67.3 ng/mL in autoimmune gastritis patients (n=62) without enterochromaffin-like cell hyperplasia, and 303.3±102.82 ng/mL in patients (n=126) with enterochromaffin-like cell hyperplasia (p<0.001). The presence of corpus atrophy (p=0.026, OR: 5.03, CI 95%: 1.21-20.88, β=1.61) and presence of enterochromaffin-like cell hyperplasia (p=0.017, OR: 6.59, CI 95%: 1.4-31.08, β=1.88) were found as risk factors associated with serum chromogranin A level. Factors influencing raised serum chromogranin A levels in autoimmune gastritis were the presence of ECL cell hyperplasia and serum gastrin levels. Serum chromogranin A levels maybe helpful in distinguishing autoimmune gastritis patients and gastric carcinoid type I from the control group, but not useful in the differentiation of individuals with autoimmune gastritis from patients with gastric carcinoids.

    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. 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. 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). 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.

    Helicobacter pylori is one of the most common causes of chronic gastritis. With the development of the disease cellular inflammatory infiltrates composed of lymphocytes, plasma cells, and macrophages are formed in epithelium and lamina propria of the stomach. These cells are capable of secreting a number of active substances, including inducible nitric oxide synthase (iNOS). We examined the relationship between H. pylori and secretion of iNOS by cells of inflammatory infiltrates in chronic gastritis by light microscopy and immunohistochemistry. The data obtained indicate that stimulation of H. pylori immune system cells of the host organism during development of chronic gastritis causes increase in number of macrophages and lymphocytes in the inflammatory infiltrate of the gastric mucosa. This is accompanied with increased expression of inducible NO-synthase with excess free radicals in the tissues, which leads to secondary alterations and exacerbates the inflammation with impaired regeneration processes.

    Although Helicobacter pylori infection is prevalent in our country, there are few studies evaluating the associated histological abnormalities in children. To evaluate the histological features of the gastric mucosa in children and adolescents with Helicobacter pylori gastritis. One hundred and thirty two gastric biopsies from 22 symptomatic patients infected with H. pylori (14F/8M, median age 10 y 5 mo, age range 2 y 11 mo to 16 y 9 mo) were evaluated. Evaluated gastric regions included: antrum (lesser and greater curvature), corpus (lesser and greater curvature), incisura angularis and fundus. Histological examination was performed according to the Updated Sydney System, and regional scores for polymorphonuclear and mononuclear cell infiltrate as well as bacterial density were generated. Fifteen (68.2%) patients presented H. pylori-chronic active gastritis, six (27.3%) presented antrum-predominant H. pylori-chronic active gastritis, and one (4.5%) presented corpus-predominant H. pylori-chronic active gastritis. Polymorphonuclear cell infiltrate and mononuclear cell infiltrate were observed in 93.9% and 98.5% of the biopsy specimens, respectively. Higher histological scores for polymorphonuclear infiltrate, mononuclear infiltrate, and bacterial density were observed in the gastric antrum. Intestinal metaplasia and gastric atrophy were not identified in any patient. Lymphoid aggregates and lymphoid follicles were observed in the gastric antrum of three (13.6%) and seven (31.8%) patients, respectively, but they were not related to antral nodularity. Chronic active gastritis was observed in all patients with H. pylori infection. However, antral or corporeal predominance was not observed in most patients.

    Helicobacter pylori stimulates the host's toll-like receptors (TLRs). Single-nucleotide polymorphism (SNP) of TLRs is related to the manipulation of regulatory cytokines and also implicated in the varied outcomes of the inflammatory response, including the development of precancerous lesions of gastric mucosa and disease progression. We hypothesized that TLR10 rs10004195 polymorphism is associated with gastric mucosal patterns. TLR10 rs10004195 polymorphisms were identified in a total of 400 gastritis patients using the TagMan SNP genotyping assay. Gastric mucosal patterns were classified by Conventional Narrow Band Imaging gastroscopy (C-NBI gastroscopy). Logistic regression was used to analyze the association. The gastritis patients was Type 1, 37.5% of Thai patients. The T/T homozygous genotype was exhibited by the highest percentage (46.5%) of patients, and the A/A homozygous and A/T heterozygous genotypes were exhibited by 20.25% and 33.25%, respectively, of patients. TLR10 rs10004195 was significantly associated with gastric mucosal patterns. After adjusting for confounding factors, patients with the A/A homozygous genotype showed a significantly increased risk of severe inflammation (OR=1.35, 95% CI=0.97-2.13, p=0.028). Patients with the A/T heterozygous and T/T homozygous genotypes showed a significantly increased risk of mild inflammation (OR=1.24, 95% CI=0.78-2.07, p=0.042 and OR=1.78, 95% CI=0.51-3.35, p=0.001, respectively). Our results indicate that the presence of TLR10 rs10004195, A/T heterozygous, and T/T homozygous genotypes is associated with type 1, 2, and 3 whereas that of the A/A homozygous genotype is associated with type 4 and 5 of gastric mucosal patterns. This suggests that the A/A homozygous genotype contributes to severe inflammation in H. pylori-associated gastritis in Thai patients.

    Elderly patients with autoimmune gastritis might have different symptoms than those of young patients. The aim of the present study was to compare presented symptoms and laboratory parameters associated with autoimmune gastritis in both old and young age groups. A total of 355 patients with autoimmune gastritis were stratified into two groups: 65 years or older (n = 119, mean age 69.47 ± 5.027 years), and under 65 years (n = 236, mean age 45.79 ± 10.51 years). These two groups were then evaluated and compared by means of clinical symptoms, concurrent autoimmune diseases, serum gastrin, vitamin B 12 and chromogranin A levels, and the presence of enterochromograffin-like cell hyperplasia. Among 119 older patients, 35 had dyspeptic symptoms, and 84 patients were referred for vitamin B 12 and/or iron deficiency. In the younger group (n = 236), there were more patients who had dyspeptic symptoms (36 vs 200, P < 0.001). Serum gastrin (726.68 ± 266.183 vs 214.36 ± 104.62 pg/mL, P < 0.001) and chromogranin A (301.26 ± 172.95 vs 106.59 ± 67.66 ng/mL, P < 0.001) levels were significantly higher, and the presence of enterochromograffin-like cell hyperplasia was more frequent (113 vs 31, P < 0.001) in older patients than younger patients. Polyautoimmunity (66.3% vs 24.5%) and multiple autoimmune syndrome (17.6% vs 5.5%) were more common in older patients (P < 0.001). There are differences in the clinical characteristics and the laboratory parameters between patients with autoimmune gastritis that are older and younger than 65 years-of-age. Elderly patients with autoimmune gastritis were investigated more commonly for vitamin B 12 and/or iron deficiency. Polyautoimmunity and multiple autoimmune syndrome were more common, and serum gastrin and chromogranin A levels were significantly higher in older patients.

    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.

    Chronic inflammation is the hallmark of the pathogenesis of H. pylori-induced gastric cancer. IL-17A and IL-17F are inflammatory cytokines expressed by a novel subset of CD4+Th cells and play critical function in inflammation. We evaluated the relationship between IL-17A G197A, IL-17F A7488G and IL23R+2199 A/C polymorphisms with IL-6, IL-17, IL-21, IL-23 and TGF-β1 mRNAs expression in regard to H. pylori infection with chronic gastritis. Total RNA and genomic DNA were extracted from gastric biopsies of 58 H. pylori-infected patient with gastritis. Afterward, mucosal IL-6, IL-17, IL-21, IL-23 and TGF-β1 mRNAs expression and polymorphisms in IL-17A G197A, IL-17F A7488G and IL-23R +2199A/Cin gastric biopsies were determined by real-time PCR and PCR-RFLP. Our results show that IL-17A G197A, IL-17F A7488G andIL23R +2199A/C polymorphisms have no effect on mucosal expression of IL-6, IL-17, IL-21 and TGF-β1 mRNAs expression in H. pylori-infected patients with chronic gastritis. These results suggest that IL-17A G197A, IL-17F A7488G and IL23R +2199A/C polymorphisms no alter mucosal cytokine pattern in Iranian patients with H. pylori-associated gastritis diseases. © Acta Gastro-Enterologica Belgica.

    Epstein-Barr virus (EBV) infection can be presented with various clinical manifestations and different levels of severity when infected. Infectious mononucleosis, which is most commonly caused by EBV infection in children and adolescents, is a clinical syndrome characterized by fatigue, malaise, fever, sore throat, and generalized lymphadenopathy. But rarely, patients with infectious mononucleosis may present with gastrointestinal symptoms and complicated by gastritis, splenic infarction, and splenic rupture. We encountered a 16-year-old girl who presented with fever, fatigue, and epigastric pain. Splenic infarction and EBV-associated gastritis were diagnosed by using esophagogastroduodenoscopy and abdominal computed tomography. Endoscopy revealed a generalized hyperemic nodular lesion in the stomach, and the biopsy findings were chronic gastritis with erosion and positive in situ hybridization for EBV. As splenic infarction and acute gastritis are rare in infectious mononucleosis and are prone to be overlooked, we must consider these complications when an infectious mononucleosis patient presents with gastrointestinal symptom.

    There are data to suggest the existence of non-Helicobacter pylori gastritis. However, the risk factors and clinical course for H pylori-negative gastritis remain unclear. We aimed to examine the prevalence and determinants of H pylori-negative gastritis in a large multiethnic clinical population. We conducted a cross-sectional study among patents scheduled for an elective esophagastroduodenoscopy or attending selected primary care clinics and eligible for screening colonoscopy at a single Veterans Affairs medical center. We identified cases of H pylor-negative gastritis, H pylori-positive gastritis, and H pylori-negative nongastritis, where gastritis was defined by the presence of neutrophils and/or mononuclear cells. Risk factors for H pylori-negative gastritis were analyzed in logistic regression models. A total of 1240 patients had information from all biopsy sites, of whom 695 (56.0%) had gastritis. H pylori-negative gastritis was present in 123 patients (9.9% of all study subjects and 17.7% of all patients with gastritis). Among all patients with gastritis, African Americans were statistically significantly less likely than non-Hispanic whites to have H pylori-negative gastritis (odds ratio, 0.25; 95% confidence interval, 0.14-0.43). Conversely, PPI users were more likely to have H pylori-negative gastritis than H pylori-positive gastritis compared with nonusers (odds ratio, 2.02; 95% confidence interval, 1.17-3.49). The cumulative incidence of gastric erosions and ulcers were higher in patients with H pylori-negative gastritis than H pylori-negative nongastritis. We found that H pylori-negative gastritis was present in approximately 18% of patients with gastritis. The potential for H pylori-negative gastritis to progress or the risk of gastric cancer of those with gastric mucosal atrophy/intestinal metaplasia remains unclear. Copyright © 2017 AGA Institute.

GPX is one of human antioxidative defense system allows the elimination of excess ROS. A cross-sectional study was in 80 consecutive gastritis patients who came to the endoscopic unit of Adam Malik General Hospital and PermataBunda Hospital in Medan, Indonesia, from May–September 2017, to determine the difference of GPX serum level between positive and negative infected H. pylori. the diagnosis of gastritis used Histopathology. Rapid urease test for diagnosis of H. pylori infection. Serum samples were obtained to determined circulating GPX. It used Univariate and bivariate analysis (Mann Whitney U test). There were 50 patients (62.5%) infected with H. pylori. GPX levels in patients with positive H. pylori gastritis were lower than those of negative H. pylori but did not differ significantly. In conclusion, there were no significant differences in GPX level between positive and negative infected H. pylori patients.

    Helicobacter pylori (Hp) infection is a common and universally distributed bacterial infection. It is predominantly acquired in childhood. To assess the relationship between endoscopic nodular gastritis and Hp infection. A retrospective study was conducted in children who underwent upper gastrointestinal endoscopy for chronic abdominal pain. All children who had five gastric biopsies for histologic analysis, urease test and Hp culture were included in the study. The Sensitivity and sensibility of nodular gastritis were determined and different parameters were studied according the presence or not of nodular gastritis(age, gender, Hp status, gastritis score and lymphoid follicles). 49 children, mean age 6.9 ± 3 years (range 1-12 years) were eligible for the analysis. Hp Infection was diagnosed in 35 out of the 49 children (71.5 %). Nodular gastritis was recorded in 16 out of 49 children and in 14 infected children and 2 out of 14 non infected children (p=0.07), 40% sensitivity, 85.7% specificity, 87.5% positive predictive value, and 36,4% negative predictive value. The parameters associated significantly to the presence of nodular gastritis were older age: (p=0.04), Hp infection: (p=0.01), chronic gastritis: (p=0.05), active gastritis: (p=0.02), follicular gastritis: (p=0.005), higher gastritis score: (p=0.005). Completely normal gastric mucosal histology was never found in infected children with antral nodularity. Among all infected children, the gastritis score was significantly higher when there was a nodular gastritis and follicular gastritis was significantly associated to nodular gastritis. The endoscopic pattern of antral nodularity identifies children with Hp infection, and active chronic follicular gastritis.

    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.

    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.

    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.

    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.

    Nodularity on the gastric mucosa is occasionally seen in general practice. There is no consensus about the association of nodular gastritis and histological premalignant lesions. This study is designed to investigate the prevalence of histological premalignant lesions in dyspeptic patients with endoscopic nodular gastritis. Consecutive patients with endoscopic nodular gastritis were compared with an age- and sex-matched control group. Endoscopic nodular gastritis was defined as a miliary nodular appearance of the gastric mucosa on endoscopy. Biopsy samples of stomach tissue were examined for the presence of atrophic gastritis, intestinal metaplasia, and dysplasia. The presence of Helicobacter pylori infection was determined by histology. From 5366 evaluated patients, a total of 273 patients with endoscopic nodular gastritis and 1103 participants as control group were enrolled. H. pylori infection was detected in 87.5% of the patients with endoscopic nodular gastritis, whereas 73.8% of the control group were positive for H. pylori (p < 0.001). Prevalence of incomplete intestinal metaplasia (p = 0.016) and dysplasia (p < 0.001) in patients with endoscopic nodular gastritis were significantly higher than in the control group. Prevalence of atrophic gastritis and complete intestinal metaplasia were also more frequent in patients with endoscopic nodular gastritis than in the control group. Dysplasia, incomplete intestinal metaplasia and H. pylori infection are significantly more frequent in patients with endoscopic nodular gastritis. Although further studies are needed before a clear conclusion can be reached, we suggest that endoscopic nodular gastritis might serve as a premalignant lesion and could be biopsied in all patients for the possibility of histological premalignancy, in addition to H. pylori infection.

    The factors influencing new markers of gastro-esophageal reflux disease detected by impedance-pH monitoring - mean nocturnal baseline impedance (MNBI) and post-reflux swallow-induced peristaltic wave (PSPW) index - need to be evaluated. To compare endoscopy-negative heartburn with chronic autoimmune atrophic gastritis (CAAG). 24 patients with CAAG, 25 with non-erosive reflux disease (NERD) and 25 with functional heartburn (FH) were included. In all patients the main impedance-pH monitoring parameters were calculated. CAAG and NERD patients had a number of reflux events (non-acid ones being more common among the former group) which was higher than that found in FH (p<0.001). MNBI decreased progressively in FH (>3000Ohm), CAAG (>2000Ohm) and NERD (<1000Ohm) patients (p=0.0046). The PSPW index was similar between CAAG and NERD patients but significantly lower in comparison to FH (p<0.0001). Patients with CAAG have evidence of non-acid reflux based on the high number of reflux events and confirmed by low values of MNBI and PSPW index. MNBI is a strong marker of acid/non-acid reflux-induced mucosal damage, whereas the PSPW index can reliably discriminate patients with reflux from those with FH, independently of the acidity of refluxate.

    BACKGROUND Reflux disease is a common gastrointestinal problem. The association between reflux disease and gastritis pattern is controversial. To determine the association between reflux disease and gastritis pattern in patients with Helicobacter pylori (H. pylori) infection. METHODS 470 patients with dyspepsia and reflux disease were enrolled in this study. The inclusion criteria were willing to participate in the study, age over 40 years, and having the criteria of ROME III for at least 3 months. Patients with history of H. pylori eradication therapy during the 3 months before the study, a history of gastric surgery, and gastric cancer were excluded. All of the participants underwent upper endoscopy and two biopsy samples were taken from antrum, body, and fundal areas. RESULTS H. pylori infection rate was 367 (78.1%) with mean age of 59.8 ± 11.4 years. Of them 131 patients (35.7%) were male. Reflux disease was detected in 273 (74.4%) patients. 216 (58.9%) and 102 (27.8%) patients had non-erosive reflux disease (NERD) and gastroesophageal reflux disease (GERD), respectively. Corpus predominant and antral predominant gastritis were seen in 72 (19.6%) and 129 (35.2%) patients, respectively. Antral gastritis was significantly associated with GERD ( p <0.01). In regression analysis, antral predominant gastritis had a significant association with GERD (OR=1.92; 95%CI: 1.22- 3.12). The same result was observed in mild to moderate antral and greater curvature gastritis (OR= 1.26; 95%CI: 0.25-6.40 and OR= 3.0; 95%CI: 0.63-14.17, respectively). CONCLUSION According to these finding ,we could suggest that the pattern of gastritis could be associated with reflux disease and GERD.

    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.

The vacuolating cytotoxin (vacA), cagA gene, oipA and babA2 gene are important virulence factor involving gastric diseases. The objective of this study was to assess the relationship between virulence factors of H. pylori and histopathological findings. Gastroduodenoscopy was performed in 436 dyspeptic patients. Antrum biopsy was obtained for detection of H. pylori, virulence factors and for histopathological assessment. The polymerase chain reaction was used to detect virulence factors of H. pylori using specific primers. vacA genotypes in patients infected with H. pylori were associated with cagA, iceA1 and iceA2. In the patients with H. pylori infection there was a significant relationship between cagA positivity and neutrophil activity (P = 0.004) and chronic inflammation (P = 0.013) and with H. pylori density (P = 0.034). Neutrophil infiltration was found to be more severe in the s1 group than in the s2 group (P = 0.042). Also was a significant relationship between oipA positivity and neutrophil activity (P = 0.004) and with H. pylori density (P = 0.018). No significant relationships were observed between other vacA genotypes and histopathological parameters. H. pylori strains showing cagA, vacA s1 and oipA positivity are associated with more severe gastritis in some histological features but virulence factors of H. pylori do not appear to determine the overall pattern of gastritis.

    Objective The Kyoto gastritis classification categorizes the endoscopic characteristics of Helicobacter pylori (H. pylori) infection-associated gastritis and identifies patterns associated with a high risk of gastric cancer. We investigated its efficacy, comparing scores in patients with H. pylori-associated gastritis and with gastric cancer. Methods A total of 1,200 patients with H. pylori-positive gastritis alone (n=932), early-stage H. pylori-positive gastric cancer (n=189), and successfully treated H. pylori-negative cancer (n=79) were endoscopically graded according to the Kyoto gastritis classification for atrophy, intestinal metaplasia, fold hypertrophy, nodularity, and diffuse redness. Results The prevalence of O-II/O-III-type atrophy according to the Kimura-Takemoto classification in early-stage H. pylori-positive gastric cancer and successfully treated H. pylori-negative cancer groups was 45.1%, which was significantly higher than in subjects with gastritis alone (12.7%, p<0.001). Kyoto gastritis scores of atrophy and intestinal metaplasia in the H. pylori-positive cancer group were significantly higher than in subjects with gastritis alone (all p<0.001). No significant differences were noted in the rates of gastric fold hypertrophy or diffuse redness between the two groups. In a multivariate analysis, the risks for H. pylori-positive gastric cancer increased with intestinal metaplasia (odds ratio: 4.453, 95% confidence interval: 3.332-5.950, <0.001) and male sex (1.737, 1.102-2.739, p=0.017). Conclusion Making an appropriate diagnosis and detecting patients at high risk is crucial for achieving total eradication of gastric cancer. The scores of intestinal metaplasia and atrophy of the scoring system in the Kyoto gastritis classification may thus be useful for detecting these patients.

    Gastric cancer (GC) is a typical type of inflammation-related tumor. The p42.3 gene is shown to be highly expressed in GC, but its association with gastritis remains unknown. We aimed to explore the relationship between gastric inflammation and p42.3 gene in vitro and in vivo. Normal gastric epithelial cells (GES-1) were treated with Helicobacter pylori (H. pylori) and tumor necrosis factor (TNF)-α. Total cell mRNA and protein were extracted and collected, and polymerase chain reaction and Western blot were performed to determine the relative expression of p42.3 gene. In total, 291 biopsy samples from patients with chronic non-atrophic gastritis were collected and immunohistochemistry was used to measure the p42.3 protein expression. The association between p42.3 protein expression and the clinicopathological characteristics of these patients were analyzed. Both H. pylori and TNF-α significantly enhanced the p42.3 protein expression in GES-1 cells in a time and dose-dependent manner. In addition, p42.3 gene expression was positively associated with the severity of gastric mucosal inflammation and H. pylori infection (P = 0.000). Its expression was significantly more common in severe gastric inflammation and in H. pylori-infected cases. p42.3 gene expression is associated with gastric mucosal inflammation that can be upregulated by TNF-α and H. pylori infection. © 2015 Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine and Wiley Publishing Asia Pty Ltd.

    In chronic atrophic gastritis atrophy of the stomach glands leads to intrinsic factor deficit, with consequent failure to absorb vitamin B12 and gastric achylia, which predisposes to Giardia infection which in itself leads to depletion of vitamin B12. We describe the case of a patient with peripheral and central nervous system pathology due to lack of vitamin B12 secondary to the combined effect of these two disorders. A 54 year old woman consulted us for paraesthesia and weakness of the legs which had been progressive for the previous two years. She presented with tactile hypoaesthesia, hypoparaesthesia, distal hyperreflexia and dysymmetry of the legs, ataxic-spastic gait and a positive Romberg sign. The investigations carried out showed the serum vitamin B12 level to be 3 pg/ml (N: 180-900), hemoglobin 13 g/dl and MCV 111 fl with MCHC 348/dl; neurophysiological studies: compatible with demyelinating motor polyneuropathy. Schilling test: deficit of absorption of vitamin B12 which was corrected on administration of intrinsic factor; gastroscopy; atrophic gastritis which confirmed the morbid anatomy findings. There was also flora containing Helicobacter and massive Giardia infection. Replacement and antibiotic therapy was followed by complete remission of the clinical picture. We emphasize the excellent clinical response to treatment in spite of the time elapsed since onset of symptoms.

    Toxic nitrite and N-nitroso compounds due to gastric bacterial growth are often detected in the stomach of patients with atrophic gastritis and partial gastrectomy. The aim of this study is to investigate whether breath N2O, a major metabolite of denitrification, detected after ingestion of nitrate is associated with atrophic gastritis and partial gastrectomy. Nine young, 16 normal older, nine atrophic gastritis and six partial gastrectomy subjects ingested 100 g lettuce, equal to 130 mg nitrate, and breath N2O was measured at 15-min intervals for 5 h. N2O was analyzed using an infrared-photoacoustic analyzer, and atrophic gastritis was diagnosed by pepsinogen test. The mean breath N2O concentrations were higher in the following order at all times: partial gastrectomy>atrophic gastritis>normal>young. The maximum N2O concentrations in the patients with partial gastrectomy and atrophic gastritis were 1655 +/- 296 and 1350 +/- 200 (mean +/- S.E.) ppb, respectively, which were higher than that of the normal subjects, 827 +/- 91 ppb (P < 0.05). The maximum N2O concentration in young people was 527 +/- 86 ppb, which was lower than that of the normal older people (P < 0.051). These higher N2O concentrations in gastric patients reflect bacterial growth in the stomach due to the reduction of gastric acid. Copyright 2004 Elsevier B.V.

    Small, round, yellowish-white nodules (YWN) are frequently observed in Helicobacter pylori-associated gastritis. The aim of the present study was to investigate the clinical significance of these YWN. Participants comprised 211 patients with H. pylori-associated gastritis, ranging in age from 23 to 86 years. YWN were detected in 23% of participants, more frequently in women (33%) than in men (12%; P < 0.01). YWN were observed on the antral mucosa in 4.7% of cases, lesser curvature of the corpus mucosa in 20%, greater curvature of the corpus mucosa in 0.9%, and fundic mucosa in 12%. Most YWN located on the antral mucosa showed nodular type, and most YWN located on the corpus mucosa and fundic mucosa showed flat type. On magnifying endoscopy with narrow-band imaging, YWN appeared as round whitish lesions with radial or branching microvessels on the surface and hypovascular globe structures just beneath the surface of the mucosa. Targeted biopsies of YWN revealed lymphoid follicles with lymphocyte infiltration or intense inflammatory cell infiltration. The endoscopic finding of YWN could be observed at any site of the gastric mucosa in H. pylori-associated gastritis, and represented histological lymphoid follicles. © 2014 The Authors.

    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 wasmore » 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.« less

    The coexistence of chronic autoimmune atrophic gastritis (CAAG) and primary hyperparathyroidism (PHPT) has been described previously, even if its extent and underlying mechanisms remain poorly understood. We therefore prospectively evaluated this association in two series of patients, one with CAAG and the other with sporadic PHPT. From January 2005 to March 2012, 107 histologically confirmed CAAG patients and 149 PHPT patients were consecutively enrolled. Routine laboratory assays included serum calcium, parathyroid hormone (PTH), plasma gastrin and chromogranin A (CgA). In CAAG patients with high PTH levels, ionized calcium and 25(OH)-vitamin D were evaluated. All CAAG and hypergastrinemic PHPT patients received an upper gastrointestinal endoscopy. Exclusion criteria were familial PHPT, MEN1 syndrome, treatment with proton pump inhibitor drugs, Helicobacter pylori infection and renal failure. Of the 107 CAAG patients, nine (8.4%) had PHPT and 13 (12.1%) had secondary hyperparathyroidism stemming from vitamin D deficiency. Among the 149 PHPT patients, 11 (7.4%) had CAAG. Gastrin and CgA levels were similar in the CAAG patients with vs those without hyperparathyroidism (either primary or secondary), and calcium and PTH levels were similar in the PHPT patients with vs those without CAAG. This study confirms a non-casual association between PHPT and CAAG. The prevalence of PHPT in CAAG patients is threefold that of the general population (8.4 vs 1-3%), and the prevalence of CAAG in PHPT patients is fourfold that of the general population (7.4 vs 2%). The mechanisms underlying this association remain unknown, but a potential role for autoimmunity is suggested.

    The Helicobacter pylori cag pathogenicity island (cagPAI) is involved in delivery of CagA effector protein and peptidoglycan into host cells and also in IL-8 induction in the human gastric tissue. Diversity of cagPAI may affect disease status and clinical outcome of the infected patients. Our study was aimed to investigate diversity of this island and its intactness in Iranian patients to investigate possible associations between cagPAI integrity and pathological changes of the infected tissue. Out of the 75 patients, H. pylori strains were obtained from 30 patients with severe active gastritis (SAG) (n=11), moderate chronic gastritis (CG) (n=14) and intestinal metaplasia/dysplasia (IM) (n=5). Intactness of the cagPAI was determined using 12 sets of primer pairs specific for functionally important loci of cagPAI by polymerase chain reaction (PCR). The cagPAI positive strains were significantly observed in patients with SAG (52.4%) in comparison to those presenting CG (33.3%) and IM (14.3%). In addition, the presence of intact cagPAI was 87.5% in H. pylori strains isolated from patients with SAG, which was higher than those obtained from patients with CG (12.5%) or IM (0%). A significant increase in the frequency of cagα-cagY and cagW-cagT segments, as exterior proteins of the CagPAI, was illustrated in strains from SAG patients compared with those from patients with CG. Overall, these results strongly proposed an association between the severity of histopathological changes and intactness of cagPAI in the gastric tissue of patients infected with H. pylori.

    To summarize Professor LIU Feng-bin's clinical experience and theoretical thoughts on chronic atrophic gastritis (CAG), the study group designed a retrospective study on his case series and expert interview. First of all, the data of CAG patients treated in the First Affiliated Hospital of Guangzhou University of Chinese Medicine between 2009 and 2013, e. g. herbs, diseases, syndrome type, prescription amount and number of herbs, was collected and processed. The statistical description and binary logistic regression were used to determined the syndrome type, initial basic remedy and modification. During the statistics, a complete and sub-group analysis was performed simultaneously. After the expert interview, the syndrome type and medication were finalized. As a result, a total of 228 CAG patients aged at (50.30 ± 10.18) were collected, including 151 males (66.23%). Of them, the TCM diagnosis and syndrome type were extracted from the information of 157 patients, including 115 cases with gastric stuffiness, 23 cases with gastric pain, 19 missing cases, 2 cases with spleen-stomach weakness syndrome, 57 cases with spleen deficiency and dampness-heat syndrome, 18 cases with spleen-stomach disharmony syndrome, 23 cases with syndrome of liver depression syndrome, 21 cases with liver qi invading stomach syndrome and 26 qi and yin deficiency syndrome, respectively. All of the 228 patients used totally 104 herbs, while the subgroups with 157 patients used 94 herbs. The most frequently used 15 herbs used in each groups were analyzed to determine the initial basic remedy and modification. Subsequently, based on the information of the sub-groups with 157 patients, with the syndrome type as the dependent variable, the logistic regression analysis was made on the most frequently used 32 herbs, in order to determined the modification in herbs for different syndrome types. After experts reviewed and modified, they believed the main causes of CAG were dietary irregularities

    "Reflux" gastritis after gastrectomy is associated with various symptoms that are often detrimental to the patients' quality of life. However, prevention of the reflux does not always bring relief from the symptoms of gastritis. Helicobacter pylori (H. pylori) is now considered one of the most important pathogenetic factors in gastritis. The association between H. pylori infection and reflux gastritis after gastrectomy was investigated in the present study. In total, 115 patients who had undergone gastrectomy were entered in this study. Five biopsy specimens from the gastric remnant were taken during upper GI endoscopy. One specimen was examined pathohistologically, and the remaining four were examined for H. pylori infection. The histological degree of gastritis was determined according to the score system of Rauws et al. Forty-six patients (40%) demonstrated H. pylori infection in their stomachs. The prevalence of the infection was significantly higher in patients with conventional gastrectomy than in those with subtotal gastrectomy. The prevalence of H. pylori infection was significantly lower in patients who had undergone gastrectomy more than 4 yr ago. The histological gastritis score in patients with H. pylori infection was significantly higher than in those without H. pylori infection. Furthermore, the eradication of H. pylori in patients with both serious gastritis symptoms and no bile reflux improved the symptoms and significantly decreased the histological gastritis score. The results suggest that H. pylori is a factor in the pathogenesis of reflux gastritis after gastrectomy.

    Background: Helicobacter pylori (H. pylori) was identified in dental plaque, raising the possibility of future gastritis and peptic ulceration. Objective: This trial was to study the association between presence of H. pylori in dental plaque and in the stomachs of patients with gastritis; the effect of oral hygiene and periodontal condition on the stomach. Patients and Methods: Seventy-five Saudi adult dyspeptic patients, together with 60 healthy persons as control. Two samples of dental plaque were taken from gingival crevice of deepest pocket. One sample was kept in Christensen's urea agar and incubated for H. pylori detection by rapid urease test. The second sample was kept in 5% sheep blood agar, chocolate agar and a selective medium to culture the H. pylori. Gastric urease test was done for the same patients. Results: (1) Plaque urease test results showed 89% positive patients. (2) Dental plaque Index:- Mild dental plaque accumulation in 24%, moderate in 41%, while severe accumulation was in 35% of the patients. (3) Gingival Index: Showed mild, moderate and severe gingivitis in 17%, 48% and 35% of patients, respectively. (4) Community periodontal index of treatment needs (CPITN): Showed gingivitis, mild periodontitis and moderate periodontitis in 50%, 23% and 27% of patients, respectively. (5)Gastric urease results: 87% of patients were positive. (6)All cultured samples results were negative Conclusion: The ability to detect H. pylori in dental plaque samples offers a potential for a noninvasive test for gastric infection and would lend support for oral spread of H. pylori as the princi-pal mode of transmission. However, the presence of H. pylori in dental plaque and in the stomach (in gastritis patients) could permit not only a target for therapeutic procedures but also a monitor-ing tool for the efficacy of therapy.

    Lymphocytic gastritis is a new histopathological entity characterised by a dense lymphocytic infiltration of surface and pit gastric epithelium. Previous retrospective work has suggested that lymphocytic gastritis is related to an endoscopic form of gastropathy comprising enlarged folds, nodules and erosions, commonly denoted as varioliform gastritis. In the present prospective study, the relationship is clearly shown; nearly 82% (54/66) of the varioliform gastritis observed in four different endoscopy units correspond histologically to lymphocytic gastritis. The correlation is even better if cases showing strictly antral localisation are excluded (53/55) - that is, more than 96%. The histological concept of lymphocytic gastritis seems, however, to extend beyond varioliform gastritis as of 67 cases of lymphocytic gastritis diagnosed during the period under study, one third had no particular endoscopic expression.

    It is known that at least 90% of duodenal ulcers are caused by infection with the bacterium Helicobacter pylori. Eradicating this organism usually results in complete resolution of the disease (Rosengren, Br J Gen Pract 46(409):491-492, 1996). To study the different changes if any in stomach wall at sites other than the ulcer in chronic duodenal ulcer patients by upper Gastro-Intenstinal Endoscopy followed by histopathological examination of different parts of stomach. This study was a retrospective study conducted in the Department of General surgery, V.S.S. Medical College, Burla, Sambalpur, odisha during the period of June 2007 to May 2009. Subjects were patients with chronic duodenal ulcer who underwent endoscopic examination, gastric biopsy and rapid urease test. Chronic gastritis of antrum, followed by erythematous pangastritis was the prominent feature both in endoscopy and histopathological examination. The Inflammatory change affected the mucosa and submucosa of the stomach wall. The prevalence rate of Helicobacter pylori was 84%, the antrum being the most common affected part (84%) followed by gastric fundus (41%). Chronic superficial atrophic gastritis of antrum, followed by pangastritis is the most common pathological abnormality in stomach wall in CDU cases. Gastric antrum is the most common site for H. pylori colonization followed by fundus. Presence of H. pylori in stomach wall is associated with active on chronic gastritis.

    Monosodium glutamate (MSG) taken per os has been found to stimulate gastric secretion provoked by pentagastrin. MSG gave rise to a marked elevation of endogenic gastrin levels both in experimental animals and atrophic gastritis patients. Thirty-six patients with secretory gastric insufficiency received MSG as an additive to their food during combined therapy of their disease. The preparation proved to be well-tolerated, good stimulant of gastric secretion, efficient in digestion improvement. MSG is recommended as an adjuvant in combined therapy of atrophic gastritis.

    Helicobacter-negative gastritis is diagnosed when no organisms are detected in a gastric mucosa with typical features of Helicobacter gastritis (Hp-gastritis). If Helicobacter-negative gastritis consisted mostly of 'missed' Helicobacter infections, its prevalence should represent a constant percentage of these infections in a population, and their clinico-epidemiological features would overlap. To compare the epidemiologic patterns of Hp-positive and Hp-negative gastritis. From a pathology database, we extracted demographic, clinical and histopathological data from patients with gastric biopsies (1.2008-12.2013). We allocated patients to high (≥12%) and low (≤6%) H. pylori prevalence regions defined by ZIP code-based data. The prevalence of H. pylori-positive and -negative gastritis by sex, age and state were expressed as a per cent of the total study population stratified accordingly. Of 895 323 patients, 10.6% had Hp-gastritis and 1.5% Helicobacter-negative gastritis. Hp-gastritis, but not Helicobacter-negative gastritis, was more common in males than females (OR 1.17, 95% CI: 1.16-1.19). While Hp-gastritis was more prevalent in high than in low-prevalence areas (OR 3.65, 95% CI: 3.57-3.74), Helicobacter-negative gastritis was only minimally affected by the underlying H. pylori prevalence (1.7% vs. 1.5%). The age-specific prevalence of Hp-gastritis peaked in the 4th to 5th decades; Helicobacter-negative gastritis exhibited a low and relatively flat pattern. The geographic distribution of H. pylori-positive and -negative gastritis showed no significant correlation. Intestinal metaplasia was found in 13.0% of patients with Hp-gastritis and in 6.1% of those with Helicobacter-negative gastritis (OR 0.43, 95% CI: 0.40-0.47). These data suggest that Helicobacter-negative gastritis is, in the vast majority of cases, a nosologically and epidemiologically distinct entity that deserves further investigation. © 2014 John Wiley & Sons Ltd.

    Background: Helicobacter pylori, which is associated with many upper gastrointestinal diseases, is found in half of the population of the world. Several special stains and immunohistochemistry stain for H. pylori are available. The need for and usefulness of immunohistochemical (IHC) technique has been debated for years. Toluidine blue is a simple stain for microbiological studies and is easily available in laboratories. Therefore, this study was conducted to compare hematoxylin and eosin (H&E), Giemsa and toluidine blue staining with immunehistochemistry for detection of H. pylori in patients with gastritis and also to correlate the results of these staining methods with pathological grading. Methods: We reviewed 54 consecutive gastric biopsy specimens stained by H&E and Giemsa as well as by toluidine blue and immunohistochemistry stains for H. pylori. Results: H. pylori was positively identified by IHC in 43 (79.63%) patients, while positive samples were found in 18 (33.33%), 24 (44.44%) and 33 (61.11%) patients using H&E, Giemsa and toluidine blue staining methods. Our results showed that classical histological staining methods are not sensitive enough to identify low numbers or coccoid forms of organism, while toluidine blue and immunohistochemistry play an important role in detection of H. pylori infection. Conclusion: Toluidine blue has been proved to be much more reliable than H&E and Giemsa in detection of H. pylori. In addition, in post treatment biopsies and in biopsies with unexplained chronic active gastritis without histological evidence of H. pylori should have immunohistochemistry done to detect possible low density or coccoid form of organisms.

Clinical examination revealed lichenoid mucosal lesions of the gums adjacent to bridges and crowns that had been implanted several weeks back. Since implantation, the patient had suffered from gastrointestinal complaints (including stomach pain). Gastroscopy 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 and zirconium (IV) chloride. The crowns and bridge contained gold, palladium and zirconium chloride, 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 against the components of artificial dentition seemed to be the cause of gastritis. PMID:23192576

    There is no widely accepted histopathological definition for nodular gastritis. In this study we aim to uncover the pathologic entity responsible for the nodular appearance and to find clues about the clinical implications of nodular gastritis. Antral biopsy specimens of 160 patients with nodular gastritis and 133 patients without nodular gastritis were examined by an experienced pathologist for dysplasia, foveolar hyperplasia, inflammatory activity, intraepithelial lymphocytosis, intestinal metaplasia, and lymphoid follicle/aggregate formation, and comparative analysis was performed between the two groups of patients. The presence of intraepithelial lymphocytosis was more frequent in patients with nodular gastritis (P < 0.05). There was no difference between the two groups regarding the other pathological features such as presence of dysplasia, inflammatory activity, intestinal metaplasia, lymphoid hyperplasia, and Helicobacter pylori (H. pylori) infection. Increase of intraepithelial lymphocytes may contribute to formation of macroscopical nodules in this peculiar type of gastritis. Nodular gastritis would not indicate a new therapeutic approach in addition to the current measures for Helicobacter pylori infection.

    Radiation recall refers to chemotherapy-triggered inflammation in healthy areas previously exposed to irradiation. Chemotherapeutics known to be associated with radiation recall phenomenon include anthracyclines, taxanes and antimetabolites, such as gemcitabine and capecitabine. Case reports detailing radiation recall dermatitis and pneumonitis associated with erlotinib have been previously described in the literature, however, there are no reported cases describing radiation gastritis associated with erlotinib. We report a patient with pancreatic cancer who developed gastrointestinal bleeding secondary to radiation recall gastritis related to erlotinib exposure. A 57-year-old Hispanic male with pancreatic cancer initially received 7 cycles of FOLFIRINOX followed by capecitabine with radiation therapy for 28 fractions for a total of 5,040 cGy. Re-staging with computed tomography demonstrated stable disease. The patient was then treated with erlotinib and capecitabine for approximately two months before restaging demonstrated progressive disease. Shortly after discontinuing erlotinib and capecitabine, the patient reported maroon colored stools. Laboratory studies demonstrated a precipitous drop in hemoglobin and hematocrit from pre-treatment baseline, ultimately requiring transfusion with packed red blood cells. Subsequent esophagogastroduodenoscopy demonstrated findings consistent with radiation gastritis, with oozing in the gastric body and antrum, which was treated therapeutically with argon plasma coagulation. The patient's gastrointestinal bleed was difficult to control. Over the course of a two-month period - the patient required multiple admissions, repeat therapeutic esophagogastroduodenoscopies and transfusions. Radiation recall from erlotinib is rare but can potentially arise in any site that has been previously irradiated. There may be an association between the pathogenesis of radiation recall and erlotinib's up-regulation of the angiogenic growth factor

    Role of Helicobacter pylori infection in chronic gastritis and gastric and/or duodenal ulcers is well known. Simultaneously there are some articles in literature considering H. pylori as a cause of extra-gastrointestinal illnesses such as atopic dermatitis, chronic urticaria or acne rosacea, hypotrophy, Schoenlein-Henoch disease, atherosclerosis or hypochromic anaemia. The aim of the study. was to asses iron status in aspect of plasmatic transferrin receptors concentration among children and youth with chronic gastritis with or without Helicobacter pylori infection. Forty one patients were included as a study group. Range of age was 9-18 years. All patients were diagnosed due to chronic abdominal pains. There were 13 males and 28 females. Blood was collected from every patient for blood cell count, iron, transferrin and transferrin receptors concentration (sTfR) assessment before endoscopy of upper gastrointestinal tract. Concentration of sTfR was higher than age norm among 29 (71%) of patients. Among patients with higher level of sTfR 20 (69%) had normal haemoglobin concentration and in this group 10 patients had H. pylori infection. During analysis of 12 patients with nornal level of sTfR normal haemoglobin concentration was found and among five of them H. pylori infection was stated. Among 21 patients without H. pylori infection 14 had normal level of sTfR and 7 had higher level of sTfR which means that 33% had hidden iron deficiency (involuntary of normal Hb concentrations). Among 15 of 20 patients with H. pylori infection level of sTfR was higher which means that 75% patients with infection had hidden iron deficiency (involuntary of normal Hb concentrations). Level of plasmatic transferrin receptors can be good and sensitive indicator of iron deficiency and can be helpful in differential diagnosis of hypochromic anaemia and anaemia caused by chronic illness including chronic gastritis with Helicobacter pylori infection.

    Helicobacter-negative gastritis has been increasingly reported. Molecular techniques as the polymerase chain reaction (PCR) may detect bacterial DNA in histologically negative gastritis. To evaluate of Helicobacter PCR in gastric biopsies for the daily diagnostics of Helicobacter-negative gastritis. Over a 5-year period, routine biopsies with chronic gastritis reminiscent of Helicobacter infection, but negative by histology, were tested by using a H. pylori specific PCR. Subsequently, PCR-negative samples were re-evaluated using PCR for other Helicobacter species. Of the 9184 gastric biopsies, 339 (3.7%) with histological-negative gastritis and adequate material were forwarded to PCR analysis for H. pylori and 146 (43.1%) revealed a positive result. In 193 H. pylori DNA-negative biopsies, re-analysis using PCR primers for other Helicobacter species, revealed further 23 (11.9%) positive biopsies, including 4 (2.1%) biopsies with H. heilmannii sensu lato. PCR-positive biopsies showed a higher overall inflammatory score, more lymphoid follicles/aggregates and neutrophils (P < 0.05). No Helicobacter DNA was found in control biopsies of 48 patients with neither primer set (P < 0.0001). In 274 patients with an endoscopic description, detection of H. pylori DNA was associated with ulcers and erosions (P < 0.01). Over all, in 339 histologically-negative gastric biopsies, Helicobacter DNA was detected in 169 (49.9%) samples with at least one primer set. Molecular testing offers a sensitive and specific diagnosis to a selected group of patients, in whom adequate searches for bacteria by conventional histology have resulted in the unsatisfactory diagnosis of H. pylori-negative gastritis. © 2016 John Wiley & Sons Ltd.

    Several conditions associated with reduced gastric acid secretion confer an altered risk of developing a gastric malignancy. Helicobacter pylori-induced atrophic gastritis predisposes to gastric adenocarcinoma, autoimmune atrophic gastritis is a precursor of type I gastric neuroendocrine tumours, whereas proton pump inhibitor (PPI) use does not affect stomach cancer risk. We hypothesised that each of these conditions was associated with specific alterations in the gastric microbiota and that this influenced subsequent tumour risk. 95 patients (in groups representing normal stomach, PPI treated, H. pylori gastritis, H. pylori-induced atrophic gastritis and autoimmune atrophic gastritis) were selected from a cohort of 1400. RNA extracted from gastric corpus biopsies was analysed using 16S rRNA sequencing (MiSeq). Samples from normal stomachs and patients treated with PPIs demonstrated similarly high microbial diversity. Patients with autoimmune atrophic gastritis also exhibited relatively high microbial diversity, but with samples dominated by Streptococcus. H. pylori colonisation was associated with decreased microbial diversity and reduced complexity of co-occurrence networks. H. pylori-induced atrophic gastritis resulted in lower bacterial abundances and diversity, whereas autoimmune atrophic gastritis resulted in greater bacterial abundance and equally high diversity compared to normal stomachs. Pathway analysis suggested that glucose-6-phospahte1-dehydrogenase and D-lactate dehydrogenase were over represented in H. pylori-induced atrophic gastritis versus autoimmune atrophic gastritis, and that both these groups showed increases in fumarate reductase. Autoimmune and H. pylori-induced atrophic gastritis were associated with different gastric microbial profiles. PPI treated patients showed relatively few alterations in the gastric microbiota compared to healthy subjects. PMID:29095917

    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.

    Taraxacum coreanum Nakai has been traditionally used for treating inflammatory diseases including gastrointestinal diseases. We studied whether water extracts of Taraxacum coreanum Nakai (TCN) had a protective effect on acute and chronic gastritis induced by ethanol/HCl in an animal model of gastritis and its mechanism was also explored. In the acute study, rats were orally administered 0.15g/mL dextrin (normal-control), 0.15g/mL dextrin (control), 0.05g/mL TCN (TCN-L), 0.15g/mL TCN (TCN-H), or 0.01g/mL omeprazole (orally; positive-control), followed by oral administration of 1mL of 60% ethanol plus 150mM HCl (inducer). In the chronic study, rats were administered 10% diluted inducer in drinking water, and 0.6% dextrin, 0.2% or 0.6% TCN, and 0.05% omeprazole were administered in chow for 4 weeks. Acid content, gastric structure, oxidative stress, and markers of inflammation in the stomach tissue were measured at the end of experiment. Acute and chronic ethanol/HCl administration caused the inner layer of the stomach to redden, hemorrhage, and edema in the control group; TCN-H reduced these symptoms more effectively than did the omeprazole positive-control. Acid production and total acidity in the stomach increased in the control group, which was markedly suppressed by omeprazole. TCN also reduced the acid production and acidity, but not to the same degree as omeprazole. H-E and PAS staining revealed that in the inner layer of the stomach, cellular structure was disrupted, with an increased nuclear size and thickness, disarrangement, and decreased mucin in the control group. TCN prevented the cellular disruption in the inner layer, and TCN-H was more effective than the positive-control. This was associated with oxidative stress and inflammation. TCN dose-dependently reduced the infiltration of mast cells and TNF-α expression in the inner layer of the stomach, and decreased lipid peroxides by increasing superoxide dismutase and glutathione peroxidase expression.

    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. 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). 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). 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.

    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.

    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.

    Patients with chronic autoimmune atrophic gastritis (CAAG) often refer digestive symptoms and are prescribed antisecretory medications. Aims were to investigate: (i) gastro-esophageal reflux (GER), (ii) psychopathological profile, (iii) frequency of use and clinical benefit of antisecretory drugs. Prospective observational study on 41 CAAG patients who underwent: 24 h multichannel intra-luminal impedance-pH (MII-pH) monitoring off-therapy, standardized medical interview and psychological questionnaire (i.e., SCL-90R). The medical interview was repeated at least 1 month after MII-pH in patients who were using antisecretory drugs. Statistical analysis was performed calculating median (10th-90th percentiles) and risk ratios (RR) with 95% confidence interval. Median intra-gastric pH was 6.2 (4.6-7.0). One patient had acid reflux (AC) associated with symptoms, five had increased total reflux number and four had symptoms associated to non-acid reflux (NA) (patients referred as 'GER positive'). Using patients 'GER negative' with normal SCL-90R as reference, the RR of being symptomatic in patients GER positive was 2.1 (1.1-4.1) if SCL-90R was normal and 0.9 (0.5-1.7) if it was altered (difference in RR significant being p = 0.04). Seventeen/28 (61%) symptomatic patients were on antisecretory drugs, which were stopped in 16 of them according to results of MII-pH and clinical evaluation after 574 days (48-796) showed that symptoms were unchanged. In patients with CAAG (i) AC reflux rarely occurred whereas increased NA reflux was not infrequent both being related to symptoms in some patients, (ii) psychopathological profile has a role in symptoms' occurrence, (iii) antisecretory drugs were generally inappropriately used and clinically ineffective. © 2015 John Wiley & Sons Ltd.

    Magnifying narrow-band imaging (M-NBI) can reportedly help predict the presence and distribution of atrophy and intestinal metaplasia in the gastric corpus. However, the micro-mucosal pattern of the antrum shown by M-NBI differs from that of the corpus. We studied the distribution and histology of the micro-mucosal pattern in the antrum based on magnifying endoscopy. Endoscopic images of the greater curvature of the antrum were evaluated in 50 patients with chronic atrophic fundic gastritis (CAFG). The extent of CAFG was evaluated by autofluorescence imaging. The micro-mucosal pattern was evaluated by M-NBI and classified into groove and white villiform types. The localization of white villiform type mucosa was classified into three types in relation to the areae gastricae : null, central, and segmental types. Biopsies were taken from regions showing different micro-mucosal patterns. Associations among the extent of CAFG, micro-mucosal pattern, and histology were examined. As the extent of CAFG increased, the proportion of white villiform type mucosa increased, whereas that of groove type mucosa decreased (P=0.022). In patients with extensive CAFG, most of the areae gastricae was composed of the segmental or central type of white villiform type mucosa (P=0.044). The white villiform type mucosa had significantly higher grades of atrophy (P=0.002) and intestinal metaplasia (P<0.001) than did the groove type mucosa. White villiform type mucosa is indicative of atrophy and intestinal metaplasia in the gastric antrum. It extends to the whole or central part of the areae gastricae as CAFG becomes more extensive.

    Objective To study the detailed nature of genomic microevolution during mixed infection with multiple Helicobacter pylori strains in an individual. Design We sampled 18 isolates from a single biopsy from a patient with chronic gastritis and nephritis. Whole-genome sequencing was applied to these isolates, and statistical genetic tools were used to investigate their evolutionary history. Results The genomes fall into two clades, reflecting colonisation of the stomach by two distinct strains, and these lineages have accumulated diversity during an estimated 2.8 and 4.2 years of evolution. We detected about 150 clear recombination events between the two clades. Recombination between the lineages is a continuous ongoing process and was detected on both clades, but the effect of recombination in one clade was nearly an order of magnitude higher than in the other. Imputed ancestral sequences also showed evidence of recombination between the two strains prior to their diversification, and we estimate that they have both been infecting the same host for at least 12 years. Recombination tracts between the lineages were, on average, 895 bp in length, and showed evidence for the interspersion of recipient sequences that has been observed in in vitro experiments. The complex evolutionary history of a phage-related protein provided evidence for frequent reinfection of both clades by a single phage lineage during the past 4 years. Conclusions Whole genome sequencing can be used to make detailed conclusions about the mechanisms of genetic change of H. pylori based on sampling bacteria from a single gastric biopsy.

    Helicobacter pylori (H. pylori) infection is well known to be associated with the development of precancerous lesions such as chronic atrophic gastritis (AG), or gastric intestinal metaplasia (GIM), and cancer. Various molecular alterations are identified not only in gastric cancer (GC) but also in precancerous lesions. H. pylori treatment seems to improve AG and GIM, but still remains controversial. In contrast, many studies, including meta-analysis, show that H. pylori eradication reduces GC. Molecular markers detected by genetic and epigenetic alterations related to carcinogenesis reverse following H. pylori eradication. This indicates that these changes may be an important factor in the identification of high risk patients for cancer development. Patients who underwent endoscopic treatment of GC are at high risk for development of metachronous GC. A randomized controlled trial from Japan concluded that prophylactic eradication of H. pylori after endoscopic resection should be used to prevent the development of metachronous GC, but recent retrospective studies did not show the tendency. Patients with precancerous lesions (molecular alterations) that do not reverse after H. pylori treatment, represent the “point of no return” and may be at high risk for the development of GC. Therefore, earlier H. pylori eradication should be considered for preventing GC development prior to the appearance of precancerous lesions. PMID:24833876

    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

    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.

    We studied 20 patients in which a variety of erosive gastritis is described. We named it petechial erosive gastritis. We have to bring up that its sequence is due to the presence of the petechiae in the center of the mucosal area. Then in degrees of higher intensity erosions occur also at the center of the area mucosa. Occasionally the erosions meet, become larger and may bleed. An endoscopic classification of petechial erosive gastritis is established it rates mild, moderate, severe and hemorrhagic degrees. Even if the histopathologic study does not keep a strict correspondence with the severity of endoscopic observation of the lesions, it is possible to separate easily a petechial stage from an erosive stage. Demonstration of these lesions at their sequence from petechial to bleeding erosion constitutes an important contribution to the study of acute gastric lesions and it might open a way to a better study of the alterations of the irrigation of the gastric mucosa and the etiology of erosive lesions and acute ulcer.

    Colorectal polyps are common in Thailand, particularly in the northeastern region. The present study aimed to determine any correlation between Helicobacter pylori-associated gastritis and colorectal polyps in the Thai population. A total of 303 patients undergoing esophagogastroduodenoscopy with colonoscopy for investigation of chronic abdominal pain participated in this study from November 2014 to October 2015. A diagnosis of Helicobacter pylori associated gastritis was made if the bacteria were seen on histopathological examination and a rapid urease test was positive. Colorectal polyps were confirmed by histological examination of colorectal biopsies. Patient demographic data were analyzed for correlations. The prevalence of colorectal polyps was 77 (25.4%), lesions being found more frequently in Helicobacter pylori infected patients than non-infected subjects [38.4% vs. 12.5%; Odds Ratio (OR) (95% CI): 2.26 (1.32 - 3.86), p < 0.01]. Patients with Helicobacter pylori - associated gastritis were at high risk of having adenomas featuring dysplasia [OR (95% CI): 1.15 (1.16 - 7.99); P = 0.02]. There was no varaition in location of polyps, age group, sex and gastric lesions with respect to Helicobacter pylori status. This study showed that Helicobacter pylori associated gastritis is associated with an increased risk of colorectal polyps, especially adenomas with dysplasia in the Thai population. Patients with Helicobacter pylori-associated gastritis may benefit from concurrent colonoscopy for diagnosis of colorectal polyps as a preventive and early treatment for colorectal cancer.

    To assess whether corpus gastritis due to Helicobacter pylori protects against erosive esophagitis in an area with high prevalence of H. pylori infection. Biopsies obtained from gastric corpus and antrum in 151 patients with symptoms of gastroesophageal reflux disease were studied for presence of H. pylori and endoscopic evidence of gastritis. Presence and grade of esophagitis at endoscopy was recorded. Fifty-four (36%) patients had endoscopic esophagitis. Patients with severe esophagitis (>or= grade II) less often had active gastritis (15/45 vs. 55/98; p=0.02) and had a lower density of H. pylori (p=0.0003) than those without esophagitis. Active corpus gastritis due to H. pylori infection may protect against erosive esophagitis in patients with gastroesophageal reflux disease in the Middle East.

    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.

    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

    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.

    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 defectsmore » 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.''« less

    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. 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. 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. 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.

    To study the detailed nature of genomic microevolution during mixed infection with multiple Helicobacter pylori strains in an individual. We sampled 18 isolates from a single biopsy from a patient with chronic gastritis and nephritis. Whole-genome sequencing was applied to these isolates, and statistical genetic tools were used to investigate their evolutionary history. The genomes fall into two clades, reflecting colonisation of the stomach by two distinct strains, and these lineages have accumulated diversity during an estimated 2.8 and 4.2 years of evolution. We detected about 150 clear recombination events between the two clades. Recombination between the lineages is a continuous ongoing process and was detected on both clades, but the effect of recombination in one clade was nearly an order of magnitude higher than in the other. Imputed ancestral sequences also showed evidence of recombination between the two strains prior to their diversification, and we estimate that they have both been infecting the same host for at least 12 years. Recombination tracts between the lineages were, on average, 895 bp in length, and showed evidence for the interspersion of recipient sequences that has been observed in in vitro experiments. The complex evolutionary history of a phage-related protein provided evidence for frequent reinfection of both clades by a single phage lineage during the past 4 years. Whole genome sequencing can be used to make detailed conclusions about the mechanisms of genetic change of H. pylori based on sampling bacteria from a single gastric biopsy.

    To observe the clinical effect of warm acupuncture at Zhongwan(CV 12) for chronic atrophic gastritis(CAG) with spleen-stomach deficiency cold by the comparison with conventional acupuncture. Sixty-two patients were randomly assigned into a warm acupuncture group and a conventional acupuncture group,31 cases in each one. The acupoints in the two groups were Zhongwan(CV 12),Zusanli(ST 36),Neiguan(PC 6),Gongsun(SP 4),Qihai(CV 6),Pishu(BL 20) and Weishu(BL 21). Warm acupuncture was intervened at Zhongwan(CV 12) in the warm acupuncture group. Twirling reinforcing was applied at Zhongwan(CV 12) in the conventional acupuncture group. All the treatment was given for 3 courses continuously,5 days as one course,once a day. TCM syndrome score and symptom rating scale were observed before and after treatment in the two groups,and the effects were compared. The total effective rate was 93.5%(29/31) in the warm acupuncture group,which was better than 87.0%(27/31) in the conventional acupuncture group( P <0.05). The TCM syndrome score and symptom rating score were improved in the two groups after treatment( P <0.01, P <0.05),with more apparent improvement in the warm acupuncture group( P <0.01, P <0.05). Warm acupuncture at Zhongwan(CV 12) can improve gastrointestinal discomfort,which is better than twirling reinforcing at Zhongwan(CV 12) for CAG with spleen-stomach deficiency cold.

    This study aimed to evaluate the relationship between biliary excreted contrast media in the stomach and the presence of bile reflux gastritis. Consecutive 111 patients who underwent both gadoxetic acid-enhanced magnetic resonance cholangiography (gadoxetic MRC) and gastric endoscopy were included in this study. We performed a review of the gadoxetic-MRC image sets acquired 60 minutes after intravenous injection of contrast media and endoscopic images. We recorded amount of contrast media in the stomach. The sensitivity, specificity, and accuracy of duodenogastric bile reflux diagnosis were evaluated for the gadoxetic MRC. Statistical analysis was performed using the Fisher exact test and the linear-by-linear association test. Among the 111 patients, 39 had 60-minute delayed images showing the presence of contrast media in the stomach. Of these 39 patients, 13 had bile reflux gastritis and 5 showed bile in the stomach without evidence of erythematous gastritis. Of the 72 patients who did not show contrast media in the stomach, none had bile reflux gastritis and 2 patients showed bile staining in the stomach without evidence of erythematous gastritis. Bile reflux gastritis was significantly more frequent in patients with contrast media in the stomach on gadoxetic MRC than in those without. Patients with high-grade extension of contrast media in the stomach had significantly frequent bile reflux gastritis than did those with low-grade extension. Biliary excreted contrast media in the stomach on 60-minute delayed gadoxetic MRC has a correlation with the presence of bile reflux gastritis on endoscopic examination.

    Scarlet fever is a rare disease in adult patients. We report a patient in whom scarlet fever was associated with hypertrophic gastritis and multiple organ failure. A 62-year-old woman presented with septic shock and multiple organ failure. Bacteriological survey was negative. Abdominal tomodensitometry showed an hypertrophic gastritis. Histological analysis demonstrated a non specific gastritis without any tumoral sign. Cefotaxime and amoxicillin led to improvement and hypertrophic gastritis progressively resolved. A sandpaper rash over the body with finger desquamation, elevation of antistreptolysin O and a recent contact with an infected grandson led to the diagnosis of scarlet fever. Due to antibiotic prescription, scarlet fever is now uncommon. Although classical, ENT or gastroenteritis presentations may be puzzling for the diagnosis of scarlet fever. As 150 years ago, diagnosis of scarlet fever is still a clinical challenge.

    AIM: To determine the number of regulatory T cells (Tregs) in gastric mucosa of patients with gastritis, peptic ulcers and gastric cancer. METHODS: This study was a retrospective analysis of gastric antrum biopsy specimens from healthy controls (n = 22) and patients with gastritis (n = 30), peptic ulcer (n = 83), or gastric cancer (n = 32). Expression of CD4, CD25 and Foxp3 was determined by immunohistochemistry in three consecutive sections per sample. RESULTS: Compared with healthy controls, there was an increased number of CD25+ and Foxp3+ cells in patients with gastritis (P = 0.004 and P = 0.008), peptic ulcer (P < 0.001 and P < 0.001), and gastric cancer (P < 0.001 and P < 0.001). The ratio of CD25+/CD4+ or Foxp3+/CD4+ cells was also significantly higher in all disease groups (P < 0.001, respectively). The number of CD4+, CD25+, and Foxp3+ cells, and the ratio of CD25+/CD4+ and Foxp3+/CD4+ cells, were associated with the histological grade of the specimens, including acute inflammation, chronic inflammation, lymphoid follicle number, and Helicobacter pylori infection. The number of CD4+, CD25+ and Foxp3+ cells, and the ratio of CD25+/CD4+ and Foxp3+/CD4+ cells, were negatively associated with intestinal metaplasia among gastritis (P < 0.001, P < 0.001, P < 0.001, P = 0.002 and P = 0.002) and peptic ulcer groups (P = 0.013, P = 0.004, P < 0.001, P = 0.040 and P = 0.003). CONCLUSION: Tregs are positively associated with endoscopic findings of gastroduodenal diseases and histological grade but negatively associated with intestinal metaplasia in gastritis and peptic ulcer groups.

The association with emphysematous gastritis is rare and often fatal produced by gas -forming bacteria. We report the case of a trauma patient with type 1 diabetes mellitus, and diabetic ketoacidosis complicated with gastric mucormycosis associated with emphysematous gastritis. A male aged 32 who is involved in a car accident, who suffered head trauma, is admitted to the Intensive Care Unit, presenting diabetic ketoacidosis and upper gastrointestinal bleeding. An endoscopy was performed and an erosive esophagitis Class C, ischemia and gastric necrosis was found. A computed tomography scan showed emphysematous gastritis and gastric necrosis. He underwent total gastrectomy with a histopathology report of gastric mucormycosis. After the surgical procedure the patient died because of sepsis secondary to pulmonary mucormycosis Mucormycosis is a rare fungical disease which infrequently affects the gastrointestinal tract, being the stomach the most affected site. The mortality is high if the diagnosis is not done promptly and appropriate treatment is given. Suspecting its existence is necessary in patients with immunocompromised status to diagnose and provide timely treatment to increase survival, because of its high mortality. Copyright © 2015.

    Background. In Traditional Chinese Medicine (TCM), most of the algorithms are used to solve problems of syndrome diagnosis that only focus on one syndrome, that is, single label learning. However, in clinical practice, patients may simultaneously have more than one syndrome, which has its own symptoms (signs). Methods. We employed a multilabel learning using the relevant feature for each label (REAL) algorithm to construct a syndrome diagnostic model for chronic gastritis (CG) in TCM. REAL combines feature selection methods to select the significant symptoms (signs) of CG. The method was tested on 919 patients using the standard scale. Results. The highest prediction accuracy was achieved when 20 features were selected. The features selected with the information gain were more consistent with the TCM theory. The lowest average accuracy was 54% using multi-label neural networks (BP-MLL), whereas the highest was 82% using REAL for constructing the diagnostic model. For coverage, hamming loss, and ranking loss, the values obtained using the REAL algorithm were the lowest at 0.160, 0.142, and 0.177, respectively. Conclusion. REAL extracts the relevant symptoms (signs) for each syndrome and improves its recognition accuracy. Moreover, the studies will provide a reference for constructing syndrome diagnostic models and guide clinical practice. PMID:22719781

    Russell body gastritis (RBG) is an unusual type of chronic gastritis characterized by marked infiltration of Mott cells, which are plasma cells filled with spherical eosinophilic bodies referred to as Russell bodies. It was initially thought that Helicobacter pylori (H. pylori) infection was a major cause of RBG and that the infiltrating Mott cells were polyphenotypic; however, a number of cases of RBG without H. pylori infection or with monoclonal Mott cells have been reported. Thus, diagnostic difficulty exists in distinguishing RBG with monoclonal Mott cells from malignant lymphoma. Here, we report an unusual case of an 86-year-old-Japanese man with H. pylori-positive RBG. During the examination of melena, endoscopic evaluation confirmed a 13-mm whitish, flat lesion in the gastric antrum. Magnification endoscopy with narrow-band imaging suggested that the lesion was most likely a poorly differentiated adenocarcinoma. Biopsy findings were consistent with chronic gastritis with many Mott cells with intranuclear inclusions referred to as Dutcher bodies. Endoscopic submucosal dissection confirmed the diagnosis of RBG with kappa-restricted monoclonal Mott cells. Malignant lymphoma was unlikely given the paucity of cytological atypia and Ki-67 immunoreactivity of monoclonal Mott cells. This is the first reported case of RBG with endoscopic diagnosis of malignant tumor and the presence of Dutcher bodies. PMID:28874963

    Among Western populations, the declining incidence of Helicobacter pylori infection coincides with a growing clinical impact of autoimmune gastritis. To describe the histological phenotype of autoimmune gastritis, also to test the prognostic impact of OLGA staging in the autoimmune setting. A single-institutional series (spanning the years 2003-2011) of 562 consecutive patients (M:F ratio: 1:3.7; mean age = 57.6 ± 14.4 years) with serologically confirmed autoimmune gastritis underwent histology review and OLGA staging. Helicobacter pylori infection was ascertained histologically in 44/562 cases (7.8%). Forty six biopsy sets (8.2%) featured OLGA stages III-IV; they included all four cases of incidental epithelial neoplasia (three intraepithelial and one invasive; three of these four cases had concomitant H. pylori infection). There were 230 (40.9%) and 139 (24.7%) cases, respectively, of linear and micro-nodular enterochromaffin-like cell hyperplasia; 19 (3.4%) type I carcinoids were detected. The series included 116 patients who underwent repeated endoscopy/biopsy sampling (mean time elapsing between the two procedures = 54 months; range 24-108). Paired histology showed a significant (P = 0.009) trend towards a stage progression [the stage increased in 25/116 cases (22%); it remained unchanged in 87/116 cases (75%)]. In autoimmune gastritis, the cancer risk is restricted to high-risk gastritis stages (III-IV), and is associated mainly with concomitant H. pylori infection. OLGA staging consistently depicts the time-dependent organic progression of the autoimmune disease and provides key information for secondary gastric cancer prevention strategies. © 2012 Blackwell Publishing Ltd.

    Purpose The aim of this study was to investigate the pathologic characteristics of nodular gastritis in children and young adults infected with Helicobacter pylori (H. pylori). Materials and Methods A total of 328 patients were enrolled in this study, and the diagnosis of H. pylori infection was done with gastroduodenal endoscopy concomitant with a CLO™ test and pathologic analysis of the biopsy specimens. Diagnoses of normal, superficial gastritis, nodular gastritis, and peptic ulcer disease were made from the gastroduodenal endoscopic findings. The density of H. pylori organisms in the gastric mucosa was rated as normal, mild, moderate, or marked. The pathologic findings of nodular gastritis were based on the histopathologic findings of inflammation, immune activity, glandular atrophy and intestinal metaplasia. Each of these findings was scored as either normal (0), mild (1), moderate (2), or marked (3) according to the updated Sydney system and using visual analog scales. The gastritis score was the sum of the four histopathologic scores. Results In this study, nodular gastritis (50.6%) was most common, and mild density (51.5%) H. pylori infection was also common upon microscopic examination. Intestinal metaplasia occurred in 9 patients (2.7%). Conclusion Logistic regression revealed a significant increase in the incidence of nodular gastritis with gastritis score (p = 0.008), but not an association with sex, age, or H. pylori density. Gastritis score was the only significant factor influencing the occurrence of nodular gastritis. Intestinal metaplasia, which was originally thought to be a pre-malignant lesion, occurred in 2.7% of the patients with H. pylori infection. PMID:17461522

    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.

    AIM: To survey the detailed analyses for Helicobacter pylori (H. pylori) infection and gastric mucosal status in Myanmar. METHODS: A total of 252 volunteers with dyspeptic symptoms (155 female and 97 male; mean age of 43.6 ± 14.2 years) was participated in Yangon and Mandalay. The status of H. pylori infection was determined based on 5 different tests including rapid urease test, culture, histology, immunohistochemistry and serology. Histological scores were evaluated according to the update Sydney system and the Operative Link for Gastritis Assessment system. Pepsinogen (PG) I and PG II were measured using enzyme-linked immunosorbent assays. RESULTS: The overall prevalence of H. pylori infection was 48.0%. There was no relationship between age and infection rate. Even in young group (less than 29 years old), the H. pylori infection rate was relatively high (41.9%). The prevalence of H. pylori infection was significantly higher in Yangon than that of Mandalay. H. pylori infection was significantly associated with the presence of gastric mucosal atrophy. All 7 subjects with peptic ulcer were infected with H. pylori. Although H. pylori-positive subjects showed stronger gastritis than H. pylori-negative subjects, most cases had mild gastritis. CONCLUSION: We revealed the prevalence of H. pylori infection in patients with dyspeptic symptoms in Myanmar. The H. pylori infection was a risk factor for peptic ulcer and stronger gastritis.

    Long-term cigarette smoking may increase the risk of digestive tract pathologies, however, what is the influence smoking habit on gastric mucosa histology is still poorly elicited. The aim of the study was to compare histological evaluation of gastritis in smoker and non-smoker groups. A total of 236 patients of various H. pylori status (109 infected, 127 non-infected), clinical diagnosis (107 duodenal ulcer disease, 129 dyspepsia), and smoking habit (92 smokers, 144 non-smokers) were included. Subjects were classified as smokers if they smoked 5 or more cigarettes per day for at least 3 years. A histological examination of endoscopically obtained samples was performed by two experienced pathomorphologists blinded to the diagnoses and smoking habit. Microscopic slices of the gastric mucosa were stained with hematoxylin-eosin and Giemsa. Apart from histological diagnosis, H. pylori status was additionally confirmed by an urease test (CLO-test) at least in one of two gastric locations (antrum or corpus). In the H. pylori infected population, H. pylori density, neutrophils, and mononuclear cells infiltration in the gastric corpus mucosa were lower in smokers than non-smokers, while in the antrum the differences were not significant. In the non-infected population, no significant differences in neutrophils and mononuclear cells infiltration between smokers and non-smokers were found. Since the significant differences in studied parameters of chronic gastritis between smokers and non-smokers were found in the corpus mucosa of H. pylori infected subjects, smoking should be taken into account when a histological evaluation of the gastric mucosa in the H. pylori infected population is performed.

    Upper gastrointestinal (UGI) disorders are frequent in uremic patients and esophagogastroduodenoscopy (OGD) is an important investigation for their management. From January 1, 1997 to December 31, 1998, 57 endoscopies were performed in 96 hemodialysis patients (aged 65+/-12 years, 68 M, 28 F, dialysis duration 51+/-58 months) chronically treated in our unit in that period. The reasons for prescribing OGD were: anemia, after exclusion of poor response to EPO, in 26 patients (mean decrease in hemoglobin (Hb) levels 2.6+/-1.3 g/dl: the reference Hb level was the mean value measured before Hb decrease), dyspepsia in 11 and in preparation for renal transplantation in 20 patients. Twelve patients were diabetics, 24 smokers, 41 alcohol drinkers, 13 had hepatitis B or C, 6 were non-steroidal anti-inflammatory drugs (NSAIDs) abusers for bone pain and 21 were taking H2 receptor antagonists or proton-pump inhibitors chronically. Multiple biopsies of gastric mucosa were performed in 38 patients. Endoscopy revealed normal mucosa in 17.5% of cases, whilst chronic gastritis was diagnosed in 30%. Chronic gastritis was also the commonest microscopic abnormality diagnosed in 71.5% of biopsies. Anemic and non-anemic patients were matched and the 2 groups did not show significant differences in endoscopic findings and histological appearance. Thirteen patients had Helicobacter pylori (HP) infection demonstrated by biopsy specimen examination and were treated by metronidazole, clarithromycin and omeprazole. A logistic regression analysis was carried out in all subjects, considering the decrement in Hb as a dependent variable and demographic and clinical characteristics as independent variables. The analysis demonstrates that age (odds ratio 1.05; p < 0.05), NSAIDs abuse (odds ratio 15.6; p < 0.05) and HP infection (odds ratio 16.7; p < 0.01) were independently related to Hb decrease. In our experience, non-EPO-related anemia and dyspepsia are frequent features in hemodialysis patients

    To study the effect of mucilage obtained from cladodes of Opuntia ficus-indica (Cactaceae) on the healing of ethanol-induced gastritis in rats. 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. 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. 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.

    Key molecular players that link inflammation to carcinogenesis are prostaglandins, cytokines, nuclear factor-κB (NF-κB), chemokines, angiogenic growth factors, and free radicals, all of which lead to increased mutations and altered functions of important enzymes and proteins, for example, activation of oncogenic products and/or inhibition of tumor suppressor proteins, in inflamed tissues, thus contributing to multi-stage carcinogenesis process. Interpreted reversely, the identification of the molecular mechanisms by which chronic inflammation increases cancer risk or optimal intervention of targeted drugs or agents during the inflammation-associated carcinogenic process could be a necessary basis for developing new strategy of cancer prevention at many sites. In this review, we discuss the possibilities for cancer prevention by controlling inflammation process in Helicobacter pylori (H. pylori)-associated inflamed stomach with Korea red ginseng. Korea red ginseng is a good example of a natural herb that has ubiquitous properties that are conductive to stop inflammatory carcinogenesis that is un wanted outcome of H. pylori infection, rendering rejuvenation of chronic atrophic gastritis.

    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.

    Excision repair cross-complementing group 6 and 8 (ERCC6 and ERCC8) are two indispensable genes for the initiation of transcription-coupled nucleotide excision repair pathway. This study aimed to evaluate the interactions between single nucleotide polymorphisms of ERCC6 (rs1917799) and ERCC8 (rs158572 and rs158916) in gastric cancer and its precancerous diseases. Besides, protein level analysis were performed to compare ERCC6 and ERCC8 expression in different stages of gastric diseases, and to correlate SNPs jointly with gene expression. Sequenom MassARRAY platform method was used to detect polymorphisms of ERCC6 and ERCC8 in 1916 subjects. In situ ERCC6 and ERCC8 protein expression were detected by immunohistochemistry in 109 chronic superficial gastritis, 109 chronic atrophic gastritis and 109 gastric cancer cases. Our results demonstrated pairwise epistatic interactions between ERCC6 and ERCC8 SNPs that ERCC6 rs1917799-ERCC8 rs158572 combination was associated with decreased risk of chronic atrophic gastritis and increased risk of gastric cancer. ERCC6 rs1917799 also showed a significant interaction with ERCC8 rs158916 to reduce gastric cancer risk. The expressions of ERCC6, ERCC8 and ERCC6-ERCC8 combination have similarities that higher positivity was observed in chronic superficial gastritis compared with chronic atrophic gastritis and gastric cancer. As for the effects of ERCC6 and ERCC8 SNPs on the protein expression, single SNP had no correlation with corresponding gene expression, whereas the ERCC6 rs1917799-ERCC8 rs158572 pair had significant influence on ERCC6 and ERCC6-ERCC8 expression. In conclusion, ERCC6 rs1917799, ERCC8 rs158572 and rs158916 demonstrated pairwise epistatic interactions to associate with chronic atrophic gastritis and gastric cancer risk. The ERCC6 rs1917799-ERCC8 rs158572 pair significantly influence ERCC6 and ERCC6-ERCC8 expression.

    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.

    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. © The Author(s) 2014.

    In several studies, different risk factors other than antibiotic resistance have been documented with Helicobacter pylori eradication failure. We aimed in this study to investigate the relationship of gastric density of H. pylori, the occurrence/degree of gastric atrophy, and intestinal metaplasia (IM) with success rate of H. pylori eradication. Two hundred consecutive treatment naive patients who received bismuth containing standart quadruple treatment due to H. pylori infection documented by histopathological examination of two antral or two corpal biopsies entered this retrospective study. The updated Sydney system was used to grade the activity of gastritis, density of H. pylori colonization, atrophy, and IM. Stages III and IV of operative link for gastritis assessment (OLGA) or the operative link on gastric intestinal metaplasia assessment (OLGIM) stages was considered as severe gastritis. H. pylori eradication was determined via stool H. pylori antigen test performed 4 weeks after the end of therapy. The presence of gastric atrophy and IM was significantly higher in patients with eradication failure (p = 0.001 and 0.01, respectively). Severe gastritis (OLGA III-IV and OLGIM III-IV) rates were higher in eradication failure group. A multiple linear regression analysis showed that OLGA and OLGIM stages were to be independent risk factors for eradication failure (p = 0.03 and 0.01, respectively). Our results suggested that histopathologically severe gastritis may cause H. pylori eradication failure. In addition, we found that H. pylori density was not a risk factor for treatment failure in patients who receive quadruple treatment.

    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

    To present recent advances in stress gastritis prophylaxis in the critically ill and review considerations in selection of a prophylactic agent. Information was obtained from MEDLINE search, reference lists from articles identified in search, and from review articles. Emphasis was placed on controlled trials conducted within the last 5 years. All literature was assessed for methodology, results, and conclusions. Results of prospective, randomized trials, and meta-analyses are summarized. Histamine2-receptor antagonists, antacids, and sucralfate appear equally effective in preventing stress gastritis in the critically ill. A definitive cause-effect relationship between histamine2-receptor antagonists and increased incidence of nosocomial pneumonia has not yet been established. The indications for using a prophylactic agent and consideration in selecting an agent should include an evaluation of the following: risk factors for gastritis including the type of intensive care patient, comparative efficacy, adverse effects, drug interactions, cost, and ease of administration. The least expensive, safest agent requiring minimal monitoring is sucralfate. Prevention of stress gastritis has never been shown to reduce morbidity or mortality significantly. Controversies still exist regarding the need to provide prophylaxis, the choice of an agent, and the relative importance of previously identified risk factors. Further well-designed studies are needed before consensus can be reached.

    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.

Recruited were totally 86 CG patients who visited at the clinics of gastroenterology, First Affiliated Hospital of Guangzhou University of Traditional Chinese Medicine, including 67 patients of PWHS (30 of predominant-dampness, 30 of equal dampness and heat, and 30 of predominant-heat) and 19 patients of PQDS. Another 12 volunteers from healthy employees and students of Guangzhou University of Traditional Chinese Medicine were recruited as the control group. Their peripheral blood was collected. The Hp infection was detected using ASSURE Hp rapid test. The expressions of HSP 70 and NF-kappaB in the peripheral blood lymphocyte were detected using flow cytometry. The Hp infection rate was 37. 31% in the GS patients of PWHS and 36. 84% in the GS patients of PQDS (P>0.05). Compared with the control group, the expression of HSP 70 decreased in the PWHS predominant-heat group, and the expression of NF-kappaB increased in the PWHS predominant-heat group and the PQDS group (P<0.05). The expression of NF-kappaB were higher in the positive Hp infection patients of PWHS and PQDS than in the control group (P<0.05). The expression of HSP 70 was higher in the positive Hp infection patients of PQDS than in the negative Hp infection patients of PQDS (P<0.05). Besides, the coefficient correlation was -0. 023 between HSP 70 and Hp infection, and 0. 027 between NF-KB and Hp infection (P>0.05). The increased expression of NF-KB in the peripheral blood lymphocyte of CG patients of PWHS and PQDS might reflect the pathogenic roles of "inner evil" in Chinese medicine theories.

Lymphocytic gastritis was more prevalent in patients with gastric adenocarcinoma (16 of 130 cases; 12.3%) and primary gastric lymphoma (six of 45 cases; 13.7%) than in unselected patients undergoing endoscopy (0.83-2.5%). This suggests that these two disparate gastric tumours may share an immunological dysfunction or a common pathogenesis, and this is of interest given that Helicobacter pylori is thought to have a role in the evolution of gastric adenocarcinoma and lymphoma.

    The Helicobacter pylori is associated with the development of different diseases. The clinical outcome of infection may be associated with the cagA bacterial genotype. The aim of this study was to determine the EPIYA patterns of strains isolated from patients with gastritis and gastric adenocarcinoma and correlate these patterns with the histopathological features. Gastric biopsy samples were selected from 384 patients infected with H. pylori, including 194 with chronic gastritis and 190 with gastric adenocarcinoma. The presence of the cagA gene and the EPIYA motif was determined by PCR. The cagA gene was more prevalent in patients with gastric cancer and was associated with a higher degree of inflammation, neutrophil activity, and development of intestinal metaplasia. The number of EPIYA-C repeats showed a significant association with an increased risk of gastric carcinoma (OR = 3.79, 95% CI = 1.92–7.46, and P = 0.002). A larger number of EPIYA-C motifs were also associated with intestinal metaplasia. In the present study, infection with H. pylori strains harboring more than one EPIYA-C motif in the cagA gene was associated with the development of intestinal metaplasia and gastric adenocarcinoma but not with neutrophil activity or degree of inflammation.

    The bacterial pathogen Helicobacter pylori is the etiological agent of a range of gastrointestinal pathologies including peptic ulcer disease and the major killer, gastric adenocarcinoma. Infection with this bacterium induces a chronic inflammatory response in the gastric mucosa (gastritis). It is this gastritis that, over decades, eventually drives the development of H. pylori-associated disease in some individuals. The majority of studies investigating H. pylori pathogenesis have focused on factors that promote disease development in infected individuals. However, an estimated 85% of those infected with H. pylori remain completely asymptomatic, despite the presence of pathogenic bacteria that drive a chronic gastritis that lasts many decades. This indicates the presence of highly effective regulatory processes in the host that, in most cases, keeps a check on inflammation and protect against disease. In this minireview we discuss such known host factors and how they prevent the development of H. pylori-associated pathologies. Copyright © 2016 the American Physiological Society.

    SNP rs2294008 in Prostate Stem Cell Antigen (PSCA) and decreased PSCA expression are associated with gastric cancer. The objective of this study is to investigate the role of rs2294008 and PSCA expression in the gastritis-gastric cancer carcinogenic pathway. We conducted a case-control association study of H. pylori-infected gastritis and gastric cancer. rs2294008 was associated with the progression to chronic active gastritis (P = 9.4 × 10–5; odds ratio = 3.88, TT + TC vs CC genotype), but not with H. pylori infection per se nor with the progression from active gastritis to gastric cancer. We also assessed the association of rs2294008 with PSCA mRNA expression in the gastric mucosa at various disease stages and found that rs2294008 was associated with PSCA expression (P = 1.3 × 10–12). H. pylori infection (P = 5.1 × 10–8) and eradication therapy (P < 1 × 10–11) resulted in the reduced and increased PSCA expression, respectively, indicating negative regulation of PSCA expression by H. pylori infection. PSCA expression was decreased in severe gastritis compared with mild gastritis only among T allele carriers. Our findings revealed the regulation of PSCA expression by host genetic variation and bacterial infection might contribute to gastritis progression after H. pylori infection. PMID:29423095

    Histological gastritis is associated with gastric cancer, but its diagnosis requires biopsy. Many classifications of endoscopic gastritis are available, but not all are useful for risk stratification of gastric cancer. The Kyoto Classification of Gastritis was proposed at the 85th Congress of the Japan Gastroenterological Endoscopy Society. This cross-sectional study evaluated the usefulness of the Kyoto Classification of Gastritis for risk stratification of gastric cancer. From August 2013 to September 2014, esophagogastroduodenoscopy was performed and the gastric findings evaluated according to the Kyoto Classification of Gastritis in a total of 4062 patients. The following five endoscopic findings were selected based on previous reports: atrophy, intestinal metaplasia, enlarged folds, nodularity, and diffuse redness. A total of 3392 patients (1746 [51%] men and 1646 [49%] women) were analyzed. Among them, 107 gastric cancers were diagnosed. Atrophy was found in 2585 (78%) and intestinal metaplasia in 924 (27%). Enlarged folds, nodularity, and diffuse redness were found in 197 (5.8%), 22 (0.6%), and 573 (17%), respectively. In univariate analyses, the severity of atrophy, intestinal metaplasia, diffuse redness, age, and male sex were associated with gastric cancer. In a multivariate analysis, atrophy and male sex were found to be independent risk factors. Younger age and severe atrophy were determined to be associated with diffuse-type gastric cancer. Endoscopic detection of atrophy was associated with the risk of gastric cancer. Thus, patients with severe atrophy should be examined carefully and may require intensive follow-up. © 2017 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

    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. Copyright © 2014 Elsevier Inc. All rights reserved.

    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. © 2016 UICC.

    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.

    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.

    To evaluate current evidence for a causal relation between Helicobacter pylori infection and gastritis, duodenal ulcer, gastric cancer and nonulcer dyspepsia. A MEDLINE search for articles published in English between January 1983 and December 1992 with the use of MeSH terms Helicobacter pylori, gastritis, duodenal ulcer, gastric cancer, dyspepsia and clinical trial; abstracts were excluded. Six journals and Current Contents were searched manually for pertinent articles published in that time frame. Original studies with at least 25 patients, case reports and reviews that examined the relation between H. pylori and the four gastrointestinal disorders; 350 articles were on gastritis, 122 on duodenal ulcer, 44 on gastric cancer and 96 on nonulcer dyspepsia. The quality of the studies was rated independently on a four-point scale. The strength of the evidence was assessed using a six-point scale for each of the eight established guidelines for determining a causal relation. There was conclusive evidence of a causal relation between H. pylori infection and histologic gastritis. Koch's postulates for the identification of a microorganism as the causative agent of a disease were fulfilled for H. pylori as a causative agent of gastritis. There was strong evidence that H. pylori is the main cause of duodenal ulcers not induced by nonsteroidal anti-inflammatory drugs, but all of Koch's postulates were not fulfilled. There was moderate epidemiologic evidence of an association between chronic H. pylori infection and gastric cancer. There was a lack of convincing evidence of a causal association between H. pylori and nonulcer dyspepsia. The evidence supports a strong causal relation between H. pylori infection and gastritis and duodenal ulcer and a moderate relation between such infection and gastric cancer. Further studies are needed to clarify the role of H. pylori in these disorders. Thus far, there is no evidence of a causal relation between H. pylori and nonulcer

    To assess characteristics of oxyntic gastric atrophy (OGA) in autoimmune gastritis (AIG) compared with OGA as a consequence of Helicobacter pylori infection. Patients undergoing oesophagogastroduodenoscopy from July 2011 to October 2014 were prospectively included (N=452). Gastric biopsies were obtained for histology and H. pylori testing. Serum gastrin-17 (G17), pepsinogen (PG) I, PGII and antibodies against H. pylori and cytotoxin-associated gene A protein were determined in all patients. Antibodies against parietal cells and intrinsic factor were determined in patients with advanced (moderate to severe) OGA. Areas under the receiver operating characteristic curves (AUCs) were calculated for serum biomarkers and compared with histology. Overall, 34 patients (8.9%) had advanced OGA by histology (22 women, age 61±15 years). Current or past H. pylori infection and AIG were present in 14/34 and 22/34 patients, respectively. H. pylori-negative AIG patients (N=18) were more likely to have another autoimmune disease (OR 6.3; 95% CI 1.3 to 29.8), severe corpus atrophy (OR 10.1; 95% CI 1.9 to 54.1) and corpus intestinal metaplasia (OR 26.9; 95% CI 5.3 to 136.5) compared with H. pylori-positive patients with advanced OGA. Antrum atrophy was present in 39% of H. pylori-negative AIG patients. The diagnostic performance of G17, PG I and PGI/II was excellent for AIG patients (AUC=0.83, 0.95 and 0.97, respectively), but limited for H. pylori-positive patients with advanced OGA (AUC=0.62, 0.75 and 0.67, respectively). H. pylori-negative AIG has a distinct clinical, morphological and serological phenotype compared with advanced OGA in H. pylori gastritis. Published by the BMJ Publishing Group Limited.

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.

    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.

    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.

    Follicular gastritis is associated with Helicobacter pylori infection, but little is known of its relation to bacterial genotypes. Our aim was to establish the relation between follicular gastritis and different H. pylori strains. An analytic case-control study was conducted that included 36 patients with follicular gastritis (cases) and 83 with nonatrophic gastritis (controls). The sociodemographic information was obtained through a questionnaire. Biopsies were evaluated according to the Sydney System and the Wotherspoon scoring system. Helicobacter pylori genotyping was performed using the polymerase chain reaction technique. The quantitative variables were presented as mean and standard deviation and the qualitative variables as proportions and absolute frequency. The effect of each variable on outcome (follicular gastritis) was evaluated through the odds ratio and its 95% confidence interval. Statistical significance was set at a P<.05. Follicular gastritis was associated with Helicobacter pylori infection (OR: 13.41, CI: 1.7-103, P=.01). The CagA+ genotype was present in 56.5% of the cases and 58% of the controls. The cytotoxic VacAs1m1strain was present in 82% of the isolates in both groups. IceA1 frequency was 34.8% in the cases and 26% in the controls and the difference was not statistically significant. The population studied had elevated frequencies of cytotoxic Helicobacter pylori strains and the iceA1 genotype was more frequent in follicular gastritis.

    Histopathology is a defining endpoint in mouse models of experimental gastritis and gastric adenocarcinoma. Presented here is an overview of the histology of gastritis and gastric cancer in mice experimentally infected with Helicobacter pylori or H. felis. A modular histopathologic scoring scheme is provided that incorporates relevant disease-associated changes. Whereas the guide uses Helicobacter infection as the prototype challenge, features may be applied to chemical and genetically engineered mouse models of stomach cancer as well. Specific criteria included in the combined gastric histologic activity index (HAI) include inflammation, epithelial defects, oxyntic atrophy, hyperplasia, pseudopyloric metaplasia, and dysplasia or neoplasia. Representative photomicrographs accompany descriptions for each lesion grade. Differentiation of genuine tumor invasion from pseudoinvasion is highlighted. A brief comparison of normal rodent versus human stomach anatomy and physiology is accompanied by an introduction to mouse-specific lesions including mucous metaplasia and eosinophilic droplets (hyalinosis). In conjunction with qualified pathology support, this guide is intended to assist research scientists, postdoctoral fellows, graduate students, and medical professionals from affiliated disciplines in the interpretation and histologic grading of chronic gastritis and gastric carcinoma in mouse models.

    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. 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. 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. 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.

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.

    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.

    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.

  2. Diagnosis of Helicobacter pylori-related chronic gastritis, gastric adenoma and early gastric cancer by magnifying endoscopy.

    Evaluating the prevalence and severity of gastritis by endoscopy is useful for estimating the risk of gastric cancer (GC). Moreover, understanding the endoscopic appearances of gastritis is important for diagnosing GC due to the fact that superficial mucosal lesions mimicing gastritis (gastritis-like lesions) are quite difficult to be detected even with optimum preparation and the best technique, and in such cases tissue biopsy is often not very accurate for the diagnosis of gastric epithelial neoplasia. Magnifying endoscopy is a highly accurate technique for the detection of early gastric cancer (EGC). Recent reports have described that various novel endoscopic markers which, visualized by magnifying endoscopy with image-enhanced system (ME-IEE), can predict specific histopathological findings. Using ME-IEE with vessels and surface classification system (VSCS) may represent an excellent diagnostic performance with high confidence and good reproducibility to the endoscopists if performed under consistent conditions, including observation under maximal magnification. The aim of this review was to discuss how to identify high-risk groups for GC by endoscopy, and how to detect effectively signs of suspicious lesions by conventional white light imaging (C-WLI) or chromoendoscopy (CE). Furthermore, to characterize suspicious lesions using ME-IEE using the criteria and classification of EGC based upon VSCS. © 2016 Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine and John Wiley & Sons Australia, Ltd.

    This pilot study was devoted to the effect of static magnetic field (SMF)-exposure on erosive gastritis. 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.

    Helicobacter pylori (H. pylori) infection and eradication therapy have been known to influence gastric ghrelin and leptin secretion, which may lead to weight gain. However, the exact relationship between plasma ghrelin/leptin levels and H. pylori infection has remained controversial. The aim of this study was to investigate plasma ghrelin and leptin levels in H. pylori-positive and -negative patients, to compare the two levels of the hormones before and after H. pylori eradication, and to examine the correlation between body mass index (BMI) and active ghrelin or leptin levels, as well as that between atrophic pattern and active ghrelin or leptin levels. Seventy-two H. pylori-positive patients who underwent upper gastrointestinal endoscopy, 46 diagnosed as having peptic ulcer and 26 as atrophic gastritis, were enrolled. Control samples were obtained from 15 healthy H. pylori-negative volunteers. The extent of atrophic change of the gastric mucosa was assessed endoscopically. Body weight was measured and blood was collected before and 12 weeks after H. pylori eradication therapy. Blood samples were taken between 8 and 10 AM after an overnight fast. Plasma ghrelin levels were significantly lower in H. pylori-positive patients than in H. pylori-negative patients. In particular, plasma active ghrelin levels were significantly lower in patients with gastritis compared with patients with peptic ulcer. Plasma ghrelin levels decreased after H. pylori eradication in both peptic ulcer and gastritis patients, while plasma leptin levels increased only in peptic ulcer patients. Plasma leptin levels and BMI were positively correlated, and active ghrelin levels and atrophic pattern were weakly negatively correlated in peptic ulcer patients. H. pylori infection and eradication therapy may affect circulating ghrelin/leptin levels. This finding suggests a relationship between gastric mucosal injury induced by H. pylori infection and changes in plasma ghrelin and leptin levels.

    OBJECTIVE: To evaluate current evidence for a causal relation between Helicobacter pylori infection and gastritis, duodenal ulcer, gastric cancer and nonulcer dyspepsia. DATA SOURCES: A MEDLINE search for articles published in English between January 1983 and December 1992 with the use of MeSH terms Helicobacter pylori, gastritis, duodenal ulcer, gastric cancer, dyspepsia and clinical trial; abstracts were excluded. Six journals and Current Contents were searched manually for pertinent articles published in that time frame. STUDY SELECTION: Original studies with at least 25 patients, case reports and reviews that examined the relation between H. pylori and the four gastrointestinal disorders; 350 articles were on gastritis, 122 on duodenal ulcer, 44 on gastric cancer and 96 on nonulcer dyspepsia. DATA EXTRACTION: The quality of the studies was rated independently on a four-point scale. The strength of the evidence was assessed using a six-point scale for each of the eight established guidelines for determining a causal relation. DATA SYNTHESIS: There was conclusive evidence of a causal relation between H. pylori infection and histologic gastritis. Koch's postulates for the identification of a microorganism as the causative agent of a disease were fulfilled for H. pylori as a causative agent of gastritis. There was strong evidence that H. pylori is the main cause of duodenal ulcers not induced by nonsteroidal anti-inflammatory drugs, but all of Koch's postulates were not fulfilled. There was moderate epidemiologic evidence of an association between chronic H. pylori infection and gastric cancer. There was a lack of convincing evidence of a causal association between H. pylori and nonulcer dyspepsia. CONCLUSIONS: The evidence supports a strong causal relation between H. pylori infection and gastritis and duodenal ulcer and a moderate relation between such infection and gastric cancer. Further studies are needed to clarify the role of H. pylori in these disorders

    The purpose of this study was to find out whether transabdominal sonography may have a predictive role for detection of antral gastritis and Helicobacter pylori infection in the antrum. A total of 108 patients and 54 control participants were allocated into 3 groups: group 1, controls without any symptoms or findings of antral gastritis and H pylori infection; group 2, patients with symptoms and endoscopic findings consistent with gastritis in the absence of documented H pylori infection; and group 3, patients with symptoms and endoscopic findings consistent with gastritis and documented H pylori infection. These groups were compared in terms of demographics, antral wall thickness, mucosal layer (together with muscularis mucosa) thickness, and mucosal layer-to-antral wall thickness ratio. The groups had no statistically significant differences with respect to age, sex, body mass index, and smoking habits. However, it turned out that both antral walls and muscularis mucosa layers were thicker and the mucosal layer-to-antral wall thickness ratio was higher in groups 2 and 3 compared to group 1 (P > .001). In addition, group 3 had statistically significantly thicker antral walls and muscularis mucosa layers and a significantly increased mucosal layer-to-antral wall thickness ratio than group 2 (P < .001). Our results suggest that antral gastritis caused by H pylori infection is associated with characteristic features such as thickening of antral walls and mucosal layers on sonography. These novel clues may be useful in the diagnosis of gastritis, and unnecessary interventions and measures can be avoided in some cases. © 2014 by the American Institute of Ultrasound in Medicine.

    Jianpi Yiqi therapy (JYT) is a classical therapy in treating chronic atrophic gastritis (CAG), but the clinical effects of it are still contentious. The purpose of this article is to evaluate the efficacy and safety of JYT for CAG. Seven electronic databases including PubMed, Embase, Springer Link, CNKI (China National Knowledge Infrastructure), VIP (Chinese Scientific Journals Database), Wan-fang database, and CBM (Chinese Biomedicine Database) were searched from their inception to November 1, 2016. 13 randomized controlled trials (RCTs) with a total of 1119 participants were identified for analysis. Meta-analyses demonstrated that both JYT (RR 1.41; 95% CI 1.27, 1.57; P < 0.00001) and JYT + western medicine (RR 1.27; 95% CI 1.17, 1.38; P < 0.00001) were more efficacious than only western medicine. Furthermore, JYT had potential improvement on traditional Chinese medicine (TCM) symptoms scores such as stomachache, stomach distention, belching, fatigue, et al. In addition, no serious adverse events were reported in the selected trials. The Cochrane Collaboration’s risk of bias tool was evaluated for the weaknesses of methodological quality, while the quality level of Grades of Recommendations Assessment Development and Evaluation (GRADE) evidence classification indicated “Very low”. This meta-analysis indicates that JYT may have potential effects on the treatment of patients with CAG. However, due to limitations of methodological quality and small sample size of the included studies, further standardized research of rigorous design should be needed. PMID:28738092

    Few previous articles have analyzed the relation between infection with Helicobacter pylori (H. pylori) and primary gastric lymphoma in a large number of patients. Resected and biopsied specimens from 237 patients with primary gastric lymphoma were investigated for H. pylori using hematoxylin and eosin stain, modified Giemsa stain, and immunohistochemistry. These specimens were compared with specimens from 29 patients with chronic active gastritis, 33 with peptic ulcers, and 41 with gastric carcinoma. H. pylori was detected in 145 of 237 patients (61%) with gastric lymphoma. The frequency of H. pylori positivity was higher in patients with lymphoma restricted to the mucosa and submucosa (76%) than in those with lymphoma invading beyond the submucosa (48%) (P < 0.001), and was also higher in patients with low grade mucosa-associated lymphoid tissue lymphoma (72%) than in those with high grade tumors (55%) (P < 0.05). The frequency of H. pylori positivity in patients with lymphoma was lower than in those with chronic active gastritis (100%) (P < 0.001) or peptic ulcer (91%) (P < 0.05). In patients with lymphoma restricted to the mucosa and the superficial portion of the submucosa, the frequency of H. pylori positivity (90%) was as high as that observed in patients with chronic active gastritis and peptic ulcer. The H. pylori grading score for patients with lymphoma (0.9 +/- 1.0) was lower than for those with chronic active gastritis (1.9 +/- 0.8) (P < 0.001), peptic ulcers (2.2 +/- 1.0) (P < 0.001), or gastric carcinoma (1.2 +/- 1.1) (P < 0.05). These results suggest that H. pylori is more likely to be associated with early states of primary gastric lymphoma than with advanced states. Thus, H. pylori may disappear during the progression of primary gastric lymphoma.

    Objective This aim is to evaluate the effect of Sijunzi decoction (SJZD) treating chronic atrophic gastritis (CAG). Methods We performed searches in seven databases. The randomized controlled trials (RCTs) comparing SJZD with standard medical care or inactive intervention for CAG were enrolled. Combined therapy of SJZD plus conventional therapies compared with conventional therapies alone was also retrieved. The primary outcome included the incidence of gastric cancer and the improvement of atrophy, intestinal metaplasia, and dysplasia based on the gastroscopy and pathology. The secondary outcomes were Helicobacter pylori clearance rate, quality of life, and adverse event/adverse drug reaction. Results Six RCTs met the inclusion criteria. The research quality was low in the trials. For the overall effect rate, pooled analysis from 4 trials showed that modified SJZD plus conventional medications exhibited a significant improvement (OR = 4.86; 95% CI: 2.80 to 8.44; P < 0.00001) and without significant heterogeneity compared with the conventional medications alone. None reported the adverse effect. Conclusions Modified SJZD combined with conventional western medicines appears to have benefits for CAG. Due to the limited number and methodological flaw, the beneficial and harmful effects of SJZD for CAG could not be identified. More high-quality clinical trials are needed to confirm the results.

    Background & Aims Crohn’s disease (CD) can develop in any region of the gastrointestinal tract, including the stomach. The etiology and pathogenesis of Crohn’s gastritis are poorly understood, treatment approaches are limited, and there are not many suitable animal models for study. We characterized the features and mechanisms of chronic gastritis in SAMP1/YitFc (SAMP) mice, a spontaneous model of CD-like ileitis, along with possible therapeutic approaches. Methods Stomachs from specific pathogen-free and germ-free SAMP and AKR mice (controls) were evaluated histologically; the presence of Helicobacter spp. was tested in fecal pellets by PCR analysis. In vivo gastric permeability was quantified by fractional excretion of sucrose and epithelial tight junction protein expression was measured by quantitative reverse transcription PCR analysis. The effects of a proton pump inhibitor (PPI) or corticosteroids were measured and the ability of pathogenic immune cells to mediate gastritis was assessed in adoptive transfer experiments. Results SAMP mice developed Helicobacter-negative gastritis, characterized by aggregates of mononuclear cells, diffuse accumulation of neutrophils, and disruption of epithelial architecture; SAMP mice also had increased in gastric permeability compared with controls, without alterations in expression of tight junction proteins. The gastritis and associated permeability defect observed in SAMP mice were independent of bacterial colonization and reduced by administration of corticosteroids but not a PPI. CD4+ T cells isolated from draining mesenteric lymph nodes of SAMP mice were sufficient to induce gastritis in recipient SCID mice. Conclusions In SAMP mice, gastritis develops spontaneously and has many features of CD-like ileitis. These mice are a useful model to study Helicobacter-negative, immune-mediated Crohn’s gastritis.

    Chronic atrophic gastritis (CAG) is one of the most important pre-cancerous states with a high prevalence. Exploring of the underlying mechanism and potential biomarkers is of significant importance for CAG. In the present work, 1 H NMR-based metabonomics with correlative analysis was performed to analyze the metabolic features of CAG. 19 plasma metabolites and 18 urine metabolites were enrolled to construct the circulatory and excretory metabolome of CAG, which was in response to alterations of energy metabolism, inflammation, immune dysfunction, as well as oxidative stress. 7 plasma biomarkers and 7 urine biomarkers were screened to elucidate the pathogenesis of CAG based on the further correlation analysis with biochemical indexes. Finally, 3 plasma biomarkers (arginine, succinate and 3-hydroxybutyrate) and 2 urine biomarkers (α-ketoglutarate and valine) highlighted the potential to indicate risks of CAG in virtue of correlation with pepsin activity and ROC analysis. Here, our results paved a way for elucidating the underlying mechanisms in the development of CAG, and provided new avenues for the diagnosis of CAG and presented potential drug targets for treatment of CAG.

    2012-01-01

    Background The best sites for biopsy-based tests to evaluate H. pylori infection in gastritis with atrophy are not well known. This study aimed to evaluate the site and sensitivity of biopsy-based tests in terms of degree of gastritis with atrophy. Methods One hundred and sixty-four (164) uninvestigated dyspepsia patients were enrolled. Biopsy-based tests (i.e., culture, histology Giemsa stain and rapid urease test) and non-invasive tests (anti-H. pylori IgG) were performed. The gold standard of H. pylori infection was defined according to previous criteria. The sensitivity, specificity, positive predictive rate and negative predictive rate of biopsy-based tests at the gastric antrum and body were calculated in terms of degree of gastritis with atrophy. Results The prevalence rate of H. pylori infection in the 164 patients was 63.4%. Gastritis with atrophy was significantly higher at the antrum than at the body (76% vs. 31%; p<0.001). The sensitivity of biopsy-based test decreased when the degree of gastritis with atrophy increased regardless of biopsy site (for normal, mild, moderate, and severe gastritis with atrophy, the sensitivity of histology Giemsa stain was 100%, 100%, 88%, and 66%, respectively, and 100%, 97%, 91%, and 66%, respectively, for rapid urease test). In moderate to severe antrum or body gastritis with atrophy, additional corpus biopsy resulted in increased sensitivity to 16.67% compare to single antrum biopsy. Conclusions In moderate to severe gastritis with atrophy, biopsy-based test should include the corpus for avoiding false negative results. PMID:23272897

    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.

    Bile reflux gastritis of the remnant stomach following Roux-en-Y gastric bypass (RYGB) causing chronic abdominal pain has not been reported. We report a series of symptomatic patients with remnant gastritis treated effectively with remnant gastrectomy (RG). The objective was to report our experience with bile reflux remnant gastritis after RYGB and our outcomes following RG. Community teaching hospital. All patients undergoing RG were retrospectively reviewed for presenting symptoms, diagnostic workup, pathology, complications, and symptom resolution. Nineteen patients underwent RG for bile reflux gastritis at a mean of 4.4 years (52.3 mo, range 8.5-124 mo) after RYGB. All patients were female and presented with pain, primarily epigastric (18/19; 95%), and described as burning (11/19; 58%), with 10 (53%) reporting nausea. Endoscopy was performed preoperatively on all patients with successful remnant inspection in 13 (68%), using push endoscopy (n = 10) or operative assist (n = 3), with 12 (of 13; 92%) biopsy-positive for reactive gastropathy. Seventeen (90%) completed a hepatobiliary scintigraphy scan with 100% positivity demonstrating bile reflux across the pylorus. Surgical approach was laparoscopic or robotic in 18 (95%) with a hospital length of stay of 2.7 days (range 0-12 d), with no major complications or readmissions. Pathology of the remnant confirmed reactive gastropathy in 90% (n = 17). Ninety percent of patients (n = 17) reported sustained symptom resolution, and 11% of patients (n = 2) remained symptomatic at last follow-up. We followed all patients for a mean of 6.6 years (1-194 mo). Bile reflux gastritis of the remnant stomach is a new consideration for chronic abdominal pain months to years following RYGB. Hepatobiliary scintigraphy imaging and endoscopic biopsy are highly suggestive. RG is safe and effective treatment. Copyright © 2017 American Society for Bariatric Surgery. Published by Elsevier Inc.

    To determine the prevalence of Campylobacter pylori colonization in the healthy population we studied 54 asymptomatic volunteers and 65 patients referred because of gastrointestinal symptoms. All subjects underwent gastroscopy and gastric biopsy. C. pylori was isolated from 6 volunteers (11%) and 36 patients (55%). Histologic evidence of inflammation was present in 98% of the culture-positive subjects. Linear regression analysis revealed that the prevalence of C. pylori colonization increased with age. There was no difference in the isolation rate between the two groups when adjusted for age. Four of the six culture-positive volunteers underwent repeat endoscopy and gastric biopsy 1 year later; despite remaining asymptomatic, all still had positive culture results and histologic evidence of gastritis. We conclude that the prevalence of C. pylori-associated gastritis among symptomatic patients increases with age and that the organism may be present in the gastrointestinal tract for prolonged periods without symptoms or evidence of disease progression.

    The mechanisms underlying the transformation from chronic Helicobacter pylori gastritis to gastric extranodal marginal zone lymphoma (MALT lymphoma) are poorly understood. This study aims to identify microRNAs that might be involved in the process of neoplastic transformation. We generated microRNA signatures by RT-PCR in 68 gastric biopsy samples representing normal mucosa, gastritis, suspicious lymphoid infiltrates, and overt MALT lymphoma according to Wotherspoon criteria. Analyses revealed a total of 41 microRNAs that were significantly upregulated (n = 33) or downregulated (n = 8) in succession from normal mucosa to gastritis and to MALT lymphoma. While some of these merely reflect the presence of lymphocytes (e.g. miR-566 and miR-212) or H. pylori infection (e.g. miR-155 and let7f), a distinct set of five microRNAs (miR-150, miR-550, miR-124a, miR-518b and miR-539) was shown to be differentially expressed in gastritis as opposed to MALT lymphoma. This differential expression might therefore indicate a central role of these microRNAs in the process of malignant transformation.

    SAMP1/YitFcs mice serve as a model of Crohn's disease, and we have used them to assess gastritis. Gastritis was compared in SAMP1/YitFcs, AKR, and C57BL/6 mice by histology, immunohistochemistry, and flow cytometry. Gastric acid secretion was measured in ligated stomachs, while anti-parietal cell antibodies were assayed by immunofluorescence and enzyme-linked immunosorbent spot assay. SAMP1/YitFcs mice display a corpus-dominant, chronic gastritis with multifocal aggregates of mononuclear cells consisting of T and B lymphocytes. Relatively few aggregates were observed elsewhere in the stomach. The infiltrates in the oxyntic mucosa were associated with the loss of parietal cell mass. AKR mice, the founder strain of the SAMP1/YitFcs, also have gastritis, although they do not develop ileitis. Genetic studies using SAMP1/YitFcs-C57BL/6 congenic mice showed that the genetic regions regulating ileitis had comparable effects on gastritis. The majority of the cells in the aggregates expressed the T cell marker CD3 or the B cell marker B220. Adoptive transfer of SAMP1/YitFcs CD4(+) T helper cells, with or without B cells, into immunodeficient recipients induced a pangastritis and duodenitis. SAMP1/YitFcs and AKR mice manifest hypochlorhydria and anti-parietal cell antibodies. These data suggest that common genetic factors controlling gastroenteric disease in SAMP1/YitFcs mice regulate distinct pathogenic mechanisms causing inflammation in separate sites within the digestive tract.

    Recent studies have shown that patients with inflammatory bowel disease (IBD) are less likely to be infected with Helicobacter pylori compared with non-IBD patients. We aimed to study the prevalence of H. pylori-positive and H. pylori-negative gastritis in newly diagnosed children with IBD in comparison to those with non-IBD in Greece. All children who underwent first esophagogastroduodenal endoscopy between 2002 and 2011 were retrospectively included. Four groups were studied: patients with Crohn's disease (CD), ulcerative colitis (UC), IBD unclassified (IBDU), and non-IBD individuals (non-IBD). Helicobacter pylori infection was defined by positive culture or by positive histology and CLO test. Those children with negative or not available culture and only one positive test (histology or CLO) were further evaluated by urea breath test, and the positives were also included in the infected group. We studied 159 patients with IBD (66 CD, 34 UC, and 59 IBDU) and 1209 patients in non-IBD individuals. Helicobacter pylori gastritis was less frequent in the IBD group (3.8% vs 13.2% in the control group, p < .001), whereas IBD patients were significantly older than non-IBD children (p < .001). Children with H. pylori-negative gastritis were 3.3 times more likely to belong in the IBD group compared with H. pylori-positive patients (p = .006). Occurrence of H. pylori gastritis is less frequent in children with IBD compared with controls. Our study confirms an inverse association between H. pylori and IBD. Future studies are needed to distinguish between a true protective role of H. pylori and a confounding effect due to previous antibiotic use in children with IBD. © 2014 John Wiley & Sons Ltd.

    We report varicella-zoster virus (VZV) gastritis in a 70-year-old woman postchemotherapy for lymphoma, presenting with abdominal pain, vomiting, and delirium without rash. A gastric biopsy demonstrated viral inclusions but posed a diagnostic challenge as immunohistochemistry for cytomegalovirus and herpes simplex virus were negative, and VZV immunohistochemistry was not available. The patient developed a vesicular rash 7 days after her symptoms began. Molecular testing of the gastric biopsy and a skin swab both confirmed VZV infection. She also had probable involvement of her liver and pancreas based on imaging and serum chemistry, and possible central nervous system involvement. She recovered with appropriate antiviral therapy but later developed a postherpetic neuralgia, and chronic intrahepatic biliary strictures; liver biopsy demonstrated a cholangiopathy of uncertain etiology. A literature review of the pathogenesis, epidemiology and sequelae of VZV infection is included.

    Lymphocytic gastritis is a form of gastric inflammation characterised by a pronounced increase in lymphocytes in gastric surface and foveolar epithelium. Lymphocytic gastritis is often associated with endoscopic evidence of 'varioliform gastritis'. Lymphocytic gastritis has recently been reported to be associated with other forms of hypertrophic gastropathies. We present a case of hypertrophic gastropathy with gastric adenocarcinoma, with both Menetrier's disease and lymphocyte gastritis. Immunohistochemical studies showed that the intraepithelial lymphocytes were predominantly alpha/beta T cells as in the normal stomach and not gamma/delta T cells as in coeliac sprue. This case together with the six recently published cases suggests that Menetrier's disease and lymphocytic gastritis may be part of the same disease spectrum. Images Figure 1 Figure 2 PMID:1773969

    A polysaccharide named EP-1 was found by screening cultured mycelium of Hericium erinaceus, which was extracted and subjected to precipitation with ethanol, hollow-fiber ultrafiltration and ion-exchange chromatography. The polysaccharide has a molecular weight of approximately 3100Da and is composed of glucose, mannose and galactose, thus being a heteroglycan. EP-1 has a backbone of α-d-Glc(1→3) and β-d-Glc(1→3). The β-d-Glc(1→3) and α-d-Gal-(1→3) were regarded as branches attached to the C-4 position. The α-d-Man was regarded as a terminal residue. The anti-CAG activity was evaluated in experimental systems using a cell model for identification. The polysaccharide significantly inhibited the growth of MC cells obtained from human gastric mucosa epithelium (GES-1) cells transformed by MNNG, which were used as a chronic atrophic gastritis cell model. It also interfered with the MC cells by inducing cell cycle arrest. Thus, EP-1 shows potential for the development of new functional foods and drugs. Copyright © 2015. Published by Elsevier B.V.

    The aim of the present study was to examine the expression of FOXP3, interleukin (IL)-10, transforming growth factor (TGF)-β1, IL-17A, and T helper 17 (TH17) cells/FOXP3+ regulatory T (Treg) cells balance in the gastric mucosa of children with Helicobacter pylori infection, in relation to the gastric histopathology. Antral mucosal biopsies were obtained from 20 children with H pylori(+) gastritis and 20 age- and sex-matched normal controls. Histopathology was assessed by the updated Sydney classification. Gene expression of FOXP3, IL-10, and TGF-β1 was analyzed by quantitative real-time polymerase chain reaction. Immunohistochemical staining for FOXP3+ Treg and TH17 cells was performed. The gene expression levels of FOXP3, TGF-β1, and IL-10 messenger RNA (mRNA) and the number of FOXP3+ Treg were significantly higher in the H pylori(+) gastritis group than in the control group (P < 0.01). FOXP3 mRNA levels were correlated positively with TGF-β1 and IL-10 mRNA levels in the H pylori(+) gastritis group (P < 0.05). Furthermore, FOXP3 mRNA levels were correlated positively with the bacterial density, infiltration of polymorphonuclear cells, and mononuclear cells in the H pylori(+) gastritis group (P < 0.05). The number of TH17 cells was significantly higher in the H pylori(+) gastritis group than in the control group (P < 0.05). In addition, the number of TH17 cells was correlated negatively with the bacterial density and positively with the inflammatory scores of polymorphonuclear cells and mononuclear cells in the H pylori(+) gastritis group (P < 0.05). A negative correlation between the TH17 cells/FOXP3+ Treg ratio and the bacterial density was demonstrated in the H pylori(+) gastritis group (P < 0.05). This study suggested that a TH17/Treg balance toward a Treg-biased response favors the persistence of bacteria, causing chronic active gastritis.

    Laparoscopic single anastomosis gastric bypass (SAGB) is increasingly performed for morbidly obese patients. This pilot study aims primarily at evaluating the incidence of bile gastritis after SAGB. The occurrence of reflux oesophagitis and reflux symptoms were also assessed. This study included 20 patients having no reflux symptoms. All patients underwent a SAGB as a primary bariatric procedure by a single surgeon. Patients included consented to have an upper GI endoscopy done at 6 months postoperatively. Gastric aspirate was sent for bilirubin level assessment. Gastric and esophageal biopsies were submitted for histopathology and campylobacter-like organism (CLO) test. In our study, the rate of bile gastritis was 30%. In 18 patients, the level of bilirubin in gastric aspirate seems to be related to the degree of mucosal inflammation. The remaining two patients had microscopic moderate to severe gastritis with normal aspirate bilirubin level. Two patients with bilirubin level in aspirate more than 20 mg/dl had severe oesophagitis, gastritis with erosions, and metaplasia. Relationship between bilirubin level and histopathological findings of gastric biopsy examination was statistically significant with a P value of 0.001. The incidence of bile gastritis in this cohort is higher than reported in the literature, and this may be worrying. The correlation between endoscopic findings and patients' symptoms is poor. Bilirubin level and pH in aspirate might be useful tools to confirm alkaline reflux. Its level might help to choose candidates for revision surgery after SAGB. This needs further validation with larger sample size.

    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. Copyright © 2016 Elsevier Ltd. All rights reserved.

    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.

    Different lines of evidence support an association between Epstein-Barr virus (EBV) and gastric cancer (GC). The main understood risk factor to develop GC is infection by Helicobacter pylori (H. pylori), which triggers a local inflammatory response critical for progression from gastritis to GC. The role of EBV in early inflammatory gastric lesions has been poorly studied. A recent study proposed a cutoff value of 2000 EBV particles to identify patients with increased chances of infection of the gastric epithelium, which may favor the inflammatory process. To better understand the role of EBV in cancer progression, we analyzed 75 samples of GC, 147 control samples of non-tumor gastric tissue derived from GC patients and 75 biopsies from patients with non-atrophic gastritis (NAG). A first-round PCR was used for EBV detection in tumor and non-tumor controls and a more sensitive nested PCR for gastritis samples; both PCRs had lower detection limits above the proposed cutoff value. With this strategy 10.67% of GC, 1.3% of non-tumor controls and 8% of gastritis samples were found positive. An EBER1 in situ hybridization showed EBV infection of epithelial cells in GC and in a third of NAG samples, while in the other NAGs infection was restricted to the mononuclear cell infiltrate. EBV-positive GCs were enriched in lace and cribriform patterns, while these rare patterns were not observed in EBV negative samples. Our results support a role for EBV in GC and early precursor lesions, either as directly oncogenic infecting epithelial cells or indirectly as an inflammatory trigger. PMID:24448220

    Helicobacter pylori that is generally acquired in childhood and infects the gastric mucosa is considered to be responsible for many pathobiological changes that are linked to the pathogenesis of gastric cancer. Although the majority of studies on the subject have been carried out in adults, there are a limited number of studies on children that reflect the early period of infection and may be of greater significance. We aimed to determine the role of H. pylori infection and/or gastritis in several histopathological changes, p53, p21, and cell proliferation-associated Ki-67 antigen expression in the gastric mucosa. We studied 60 patients with a mean age of 7.5 ± 4.5 years at referral. On the basis of endoscopic appearance and the evaluation of the gastric antral specimens, the patients were divided into three groups: patients without gastritis, patients with H. pylori-positive gastritis, and patients with H. pylori-negative gastritis. To determine the expression of p53, Ki-67, and p21 in gastric biopsy specimens, immunohistochemical stains were performed. The incidence of neutrophil activity, which was one of our histopathologic parameters, was significantly higher in the H. pylori-positive gastritis group than the other two groups. The presence of lymphoid aggregate was more frequent in H. pylori ± gastritis groups than the nongastritis group. p53 expression was found to be significantly higher in the H. pylori-positive gastritis group than the nongastritis group. Ki-67 and p21 expressions were significantly more frequent in the H. pylori-positive gastritis group than the other two groups. When we evaluated the density of H. pylori, as the density of bacteria increases, we found that the expressions of p53, p21, and Ki-67 increased significantly. Expression of the studied precancerous markers in significant amounts indicates the importance of childhood H. pylori infection in the constitution of gastric cancer in adulthood.

    Lymphocytic gastritis is a histopathological entity characterised by the accumulation of small lymphocytes in the surface and foveolar epithelium. In order to investigate the correlation between endoscopy and histology in this condition, 192 observations selected on the basis of a presumed diagnosis of erosive or varioliform gastritis were reviewed. Ninety two instances corresponded to lymphocytic gastritis, while 100 did not show any particular microscopic feature and were labelled non-specific gastritis. There was a good correlation (48 of 58) between the diagnosis of the so-called varioliform gastritis and the histological evidence of lymphocytic gastritis. The correlation was even better when nodules, erosions, and enlarged folds were considered. Lymphocytic gastritis has a typical endoscopical appearance consisting of nodules, erosions, and large folds predominating in the gastric body. This contrasts with non-specific gastritis, which affects the antrum and produces erosions on a flat mucosa. Images Fig. 1 Fig. 2 Fig. 3 Fig. 4 Fig. 5 Fig. 6 PMID:3198002

    While gastrointestinal function is known to be closely related to psychological status, the influence of Helicobacter pylori-associated atrophic gastritis is currently unknown. We aimed to determine whether atrophic gastritis status or H. pylori infection is associated with psychological distress or depressed mood. We performed a cross-sectional, observational study involving 975 Japanese individuals (503 females; mean age, 44 ± 8 years) who underwent a health checkup. Psychological distress was defined as a Kessler-6 Scale score ≥13 and depressive mood as a Center for Epidemiological Studies Depression Scale score ≥ 16. The odds ratios with 95% confidence intervals assessing the risk of psychological distress or depressive mood associated with H. pylori infection (H. pylori-specific immunoglobulin G levels >10 U/mL) and atrophic gastritis status (pepsinogen I levels < 70 μg/L and pepsinogen I/II ratio < 3) were calculated using multiple logistic analysis adjusting for several covariates. Individuals with atrophic gastritis had a significantly higher risk of experiencing psychological distress, with younger females (<50 years) displaying the highest risk for psychological distress and depressive mood regardless of H. pylori infection status. Among females aged <50 years, H. pylori-seropositive participants with atrophic gastritis (HP+AG+) showed the highest risk of psychological distress (OR, 16.4; 95% CI, 3.45-94.9) and depression (OR, 2.86; 95% CI, 1.31-6.05), using HP-AG- status as the reference. Our findings support the results of previous animal studies regarding the psychological response to gastritis in humans.

    Epithelial cell proliferation in the fundic and antral mucosae was studied in 19 duodenal ulcer patients, 11 patients having undergone fundic superselective vagotomy for duodenal ulcer, and 10 controls. This was achieved through in vitro incorporation of tritiated thymidine in mucosal biopsies and radioautography. Except for increased fundic mucosal height, duodenal ulcer patients did not differ from controls for all parameters studied. In vagotomized patients, as compared to the other two groups, the labeling index was significantly enhanced in the innervated antral mucosa where atrophic gastritis developed, but there was no change in the labeling index and no worsening ofmore » mucosal inflammation in the denervated fundic mucosa. The only abnormality in the latter was a striking expansion, towards the surface, of the proliferative area within the fundic pit. The labeling indices and the degree of gastritis in gastric mucosae are significantly correlated in control and duodenal ulcer patients. If findings in antral mucosa, after superselective vagotomy, seemed related to gastritis lesions, those in fundic mucosa were not and may indicate an alteration due to the vagotomy per se.« less

Forty-eight children with healthy periodontium constituted control group. Generalized chronic catarrhal gingivitis in children with gastroduodenal pathology is characterized by intense humoral response by simultaneous T-cell immunity suppression. Detection of high serum titers of circulating immune complexes in patients with chronic catarrhal gingivitis suggests a role of immune response in the pathogenesis of periodontal disease increases with concomitant diseases of the upper gastrointestinal tract.

    Radiation recall gastritis is rare but can be induced after concurrent chemoradiation for pancreatic cancer. We report a patient with pancreatic cancer who developed radiation-recall gastritis related to a combination of gemcitabine and erlotinib. A 54-year-old female with unresectable pancreatic cancer received gemcitabine in combination with radiation therapy followed by chemotherapy with gemcitabine and erlotinib. After completing 2 cycles of chemotherapy, the patient had epigastric pain, nausea, and vomiting. Abdominal computed tomography (CT) scan revealed diffuse wall thickening of the stomach, and esophagogastroduodenoscopy (EGD) showed multiple gastric ulcers. The patient was treated with proton pump inhibitors (PPI) and was continued on maintenance chemotherapy. Two months later, the patient presented with the similar symptoms and persistent gastric ulcers were observed during subsequent EGD. Nevertheless, the patient's symptom had resolved with PPI therapy. Thus, the patient underwent maintenance chemotherapy with gemcitabine and erlotinib for additional 4 cycles. Eventually, follow-up abdominal CT Scan and EGD at 6 months demonstrated resolution of the gastric ulcers. Physicians should be aware of the possibility of radiation recall gastritis associated with a combination of gemcitabine and erlotinib. Administration of PPIs may mitigate the adverse effects of gemcitabine and erlotinib in the presence of radiation recall gastritis; however further studies are warranted.

    Focally enhanced gastritis and macrophage microaggregates are found in the upper gastrointestinal involvement of Crohn's disease, and may reflect an underlying defective innate immunity. These features, however, are also described in patients with Helicobacter pylori infection. The role of these gastric abnormalities in the diagnosis of Crohn's disease was assessed in a population with high prevalence of H. pylori infection. Thirty-seven Crohn's disease, 26 ulcerative colitis, and 30 control patients were included. The H. pylori status was evaluated by the rapid urease test and histology. The presence of focally enhanced gastritis and macrophage microaggregates was recorded. Focally enhanced gastritis was present in 24% of Crohn's disease patients, 4% of ulcerative colitis patients and 11.5% of controls, presenting an overall sensitivity and specificity for Crohn's disease of 24% and 88%, respectively. Macrophage microaggregates were found in all groups, but were only detected in ulcerative colitis and controls in association with H. pylori infection, with an overall sensitivity and specificity for Crohn's disease of 61% and 69%, respectively. In the absence of H. pylori infection, focally enhanced gastritis and macrophage microaggregates were significantly associated with Crohn's disease (P<0.02 and P = 0.001 respectively). Focally gastritis and macrophage microaggregates are suggestive of Crohn's disease only in H. pylori-negative specimens.

    Helicobacter pylori is a common cause of gastritis and peptic ulcers in humans. Many dogs, including those with gastritis and chronic vomiting, are infected with Helicobacter spp. Triple antimicrobial therapy will eradicate Helicobacter infection, improve gastritis, and reduce clinical signs. The addition of acid suppression medication will not improve results. Twenty-four pet dogs with chronic vomiting and gastric Helicobacter spp. Dogs were randomly assigned to triple antimicrobial therapy with or without famotidine. Gastroduodenoscopy was performed 4 weeks and 6 months after therapy. Helicobacter spp status was determined by histologic assessment of gastric mucosal biopsy specimens. Eradication rates for each treatment were not significantly different and combined were 75 and 42.9% at 4 weeks and 6 months, respectively. A greater improvement in gastritis scores occurred in dogs that became Helicobacter spp negative. Overall, the frequency of vomiting was reduced by 86.4%, but there were no differences between treatments. Eradication rates of Helicobacter spp with both treatments were not significantly different. Eradication rates at 6 months were modest, and more effective treatments should be developed. Acid suppression is not a necessary component of treatment protocols for dogs. Eradication of gastric Helicobacter spp was associated with improvement in gastritis scores. Dramatic reduction of the vomiting frequency occurred with both treatment protocols. Gastric Helicobacter spp may cause or contribute to chronic vomiting and gastritis in some dogs.

    Background/Aims—Interleukin 10 (IL-10) is a counterinflammatory peptide implicated in the downregulation of human intestinal immune responses. Enhanced secretion of IL-10 has been documented in gastric biopsy organ culture in Helicobacter pylori infection. This study aimed to define the cellular origins of IL-10 in H pylori associated gastritis, and to determine the effects of endogenous IL-10 on proinflammatory cytokine secretion in vitro. Methods—Endoscopic biopsies were obtained from the gastric antrum at endoscopy from patients with dyspepsia. Two pairs of antral biopsies were cultured in vitro for 24 hours, one pair in the presence of neutralising anti-IL-10 monoclonal antibody, the other pair as controls. The cytokine content of culture supernatants (tumour necrosis factor α (TNF-α), IL-6, and IL-8) was determined by enzyme linked immunosorbent assay and corrected for biopsy weight. Helicobacter pylori status was established by histology and biopsy urease test, and histopathology graded by the Sydney system. In a subgroup of patients, western blotting was used to establish CagA serological status. Immunohistochemistry for IL-10 was performed on formalin fixed tissues using a combination of microwave antigen retrieval and the indirect avidin–biotin technique. Immunoreactivity was scored semiquantitatively. Results—In vitro culture was performed in 41 patients: 31 with H pylori positive chronic gastritis and 10 H pylori negative. In vitro secretion of TNF-α, IL-6, and IL-8 for "control" biopsies was significantly higher in H pylori positive versus negative samples, with values of TNF-α and IL-6 correlating with the degree of active and chronic inflammation and being higher in CagA seropositive cases. No evidence for enhanced cytokine secretion was seen in biopsies cocultured in the presence of anti-IL-10 monoclonal antibody. Immunohistochemistry was performed in 29 patients, of whom 13 were H pylori positive. IL-10 immunoreactivity was observed in

    Lymphocytic gastritis (LG), characterized by marked intra-epithelial lymphocytosis in the gastric mucosa, has been frequently associated with both celiac disease (CD) and H. pylori gastritis. The aim of this study was to review and correlate the morphology of LG with the presence of CD and H. pylori. Gastric biopsies diagnosed with LG from 1/1/2006 to 8/1/2013 at our institution and corresponding small bowel biopsies, when available, were reviewed for verification of the diagnosis and to assess for the presence of H. pylori and CD. Immunohistochemical (IHC) staining for H. pylori was performed on all gastric biopsies. Demographic, clinical, and laboratory data were obtained from the medical record. Fifty-four of the 56 cases that met inclusion criteria demonstrated significant intra-epithelial lymphocytosis as the predominant histologic abnormality; however, none were associated with H. pylori infection by IHC staining. Two cases that also showed a prominent intra-epithelial and lamina propria neutrophilic infiltrate were both positive for H. pylori and were excluded from further study. Of the 36 small bowel biopsies available, 19 (53%) showed changes in CD. LG is not a distinct clinicopathologic entity, but a morphologic pattern of gastric injury that can be secondary to a variety of underlying etiologies. When restricted to cases with lymphocytosis alone, LG is strongly associated with CD and not with active H. pylori infection. However, cases that also show significant neutrophilic infiltrate should be regarded as "active chronic gastritis" and are often associated with H. pylori infection. A morphologic diagnosis of LG should prompt clinical and serologic workup to exclude underlying CD. © 2014 John Wiley & Sons Ltd.

    An association exists between Helicobacter pylori (H. pylori), peptic ulcers, gastritis, and sometimes gastric carcinomas. Th22 cells have protective and inflammatory roles in defense against microbes. We investigated the frequencies of Th22, Tc22, Th22/17, and Tc22/17 cells in addition to the changes in levels of cytokines IL-22, IL-6, IL-23, TNF-α, IL-1β, and TGF-β in sera from patients with H. pylori-associated gastritis, and peptic ulcer, and in uninfected patients. A total of 76 patients with H. pylori-associated disorders formed the studied group. Frequencies of T-cell subsets were determined by flow cytometry. Levels of cytokines IL-22, IL-6, IL-23, TNF-α, IL-1β, and TGF-β in the sera and supernatants of patients were measured by ELISA and flow cytometry. The study participants included 32 males and 44 females with a mean age of 38.5±15.3 years. We divided the infected group into peptic ulcer and gastritis (mild, moderate, active chronic, and chronic). The frequencies of Th22, Tc22, and Tc22/17 increased significantly in the peptic ulcer, moderate, active chronic, and chronic gastritis groups compared to the uninfected group. Th22/17 only increased significantly in the chronic gastritis group. We observed significant increases in IL-22 in the moderate and active chronic gastritis, IL-23 in the active chronic and chronic gastritis, and TNF-α in the peptic ulcer and moderate gastritis groups. Following in vitro antigenic stimulation, we observed significantly higher levels of IL-1β, IL-23, and IL-6 in the active chronic gastritis group, as well as IL-6 and IL-1β in the chronic gastritis group compared to the uninfected group. Increased Th22, Tc22, and Tc22/17 cells and IL-22 levels appear to be influential in progression and severity of H. pylori infection. Th22/17 can be an interesting therapeutic target for chronic H. pylori infections where eradication is more difficult. © 2016 John Wiley & Sons Ltd.

    Adhesive small bowel obstruction (ASBO) is common after abdominal surgery. Water soluble contrast agents (WSCA) such as Gastrografin have been demonstrated to be safe and effective in predicting resolution of ASBO with conservative management while decreasing the time to resolution, decreasing the need for surgery and reducing overall length of stay. Few adverse effects have been reported. To the authors knowledge this is the first report of haemorrhagic gastritis following administration of Gastrografin for ASBO. We present a case of haemorrhagic gastritis following Gastrografin administration in a 69-year-old male with adhesive small bowel obstruction who was managed conservatively with a good outcome. The report complies with the criteria outlined in the SCARE statement (Product Information Gastrografin [Product information], 2013). The characteristics, mechanism of action, safety profile and efficacy of Gastrografin in ASBO are discussed along with the possible mechanisms underlying the haemorrhagic gastritis. This patient at high risk of gastropathy experienced haemorrhagic gastritis following administration of Gastrografin for adhesive small bowel obstruction. WSCA such as Gastrografin are usually safe and effective in ASBO however caution may be warranted in patients at high risk of gastropathy. Copyright © 2017 The Authors. Published by Elsevier Ltd..

    To characterize clinical, laboratorial, and histological profile of pediatric autoimmune gastritis in the setting of unexplained iron deficiency anemia investigation. A descriptive, observational study including pediatric patients with a diagnosis of autoimmune gastritis (positive parietal cell antibody and gastric corpus atrophy) established in a 6 year period (2006-2011) in the setting of refractory iron deficiency anemia (refractoriness to oral iron therapy for at least 6 mo and requirement for intravenous iron therapy) investigation, after exclusion of other potentially contributing causes of anemia. Helicobacter pylori (H. pylori) infection and anti-secretory therapy were also excluded. Data were retrospectively collected from clinical files, including: demographic data (age, gender, and ethnic background), past medical history, gastrointestinal symptoms, familial history, laboratorial evaluation (Hb, serum ferritin, serum gastrin, pepsinogen I/ pepsinogen II, B12 vitamin, intrinsic factor autoantibodies, thyroid autoantibodies, and anti-transglutaminase antibodies), and endoscopic and histological findings (HE, Periodic Acid-Schiff/Alcian blue, gastrin, chromogranin A and immunochemistry analysis for CD3, CD20 and CD68). Descriptive statistical analysis was performed (mean, median, and standard deviation). We report a case-series concerning 3 girls and 2 boys with a mean age of 13.6 ± 2.8 years (3 Caucasian and 2 African). One girl had type I diabetes. Familial history was positive in 4/5 cases, respectively for autoimmune thyroiditis (2/5), sarcoidosis (1/5) and multiple myeloma (1/5). Laboratorial evaluation on admission included: Hb: 9.5 ± 0.7 g/dL; serum ferritin: 4.0 ± 0.9 ng/mL; serum gastrin: 393 ± 286 pg/mL; low pepsinogen I/ pepsinogen II ratio in 1/5 patients; normal vitamin B12 levels (analyzed in 3 patients).

    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.

    Gastric biopsies from 86 patients with pernicious anaemia were examined for Campylobacter like organisms with particular attention to those showing an antral gastritis in addition to the usual pattern of body gastritis. All the patients had chronic atrophic gastritis in the body but Campylobacter like organisms were found at this site in only three patients. Thus the Type A pattern of gastritis (autoimmune) seen in patients with pernicious anaemia is only rarely associated with Campylobacter like organisms. Forty four of these patients had biopsies from body and antrum, 16 showed an antral gastritis of whom only one had Campylobacter like organism present. Twenty five of this latter group of patients were rebiopsied after five years. There was no change in the pattern of gastritis, and the same single patient remained colonised. The frequency of an antral gastritis in patients with pernicious anaemia was 36% yet the frequency of antral colonisation by Campylobacter like organisms was very low (6%). These results show that, as in the body, Campylobacter like organisms are not associated with gastritis when it occurs at this site in pernicious anaemia. The antral gastritis that may accompany body gastritis in pernicious anaemia seems more likely therefore to be an extension of primary type A body gastritis (autoimmune) rather than a secondary type B (chronic) gastritis and, it is argued, the antrum may exhibit resistance to colonisation.

    Eradication of Helicobacter pylori may lead to improvement of chronic immune thrombocytopenic purpura (ITP), although its efficacy over time is uncertain. We report the results of H pylori screening and eradication in 75 consecutive adult patients with ITP. We also used molecular methods to investigate lymphocyte clonality and H pylori genotypes in the gastric biopsies from 10 H pylori-positive patients with ITP and 19 H pylori-positive patients without ITP with chronic gastritis. Active H pylori infection was documented in 38 (51%) patients and successfully eradicated in 34 (89%) patients. After a median follow-up of 60 months, a persistent platelet response in 23 (68%) of patients with eradicated infection was observed; 1 relapse occurred. No differences in mucosal B- or T-cell clonalities were observed between patients with ITP and control participants. Of note, the frequency of the H pylori cagA gene (P = .02) and the frequency of concomitant H pylori cagA, vacAs1, and iceA genes (triple-positive strains; P = .015) resulted statistically higher in patients with ITP than in control participants. All asymptomatic H pylori-positive patients with ITP were suffering from chronic gastritis. Our data suggest a sustained platelet recovery in a proportion of patients with ITP by H pylori eradication alone. Overrepresentation of specific H pylori genotypes in ITP suggests a possible role for bacterium-related factors in the disease pathogenesis.

    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, althoughmore » 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.« less

    Interleukin (IL)-induced inflammatory responses are critical for the pathogenesis of Helicobacter pylori (H. pylori)-induced gastritis. IL-33 represents a recently discovered proinflammatory cytokine involved in inflammatory diseases, but its relevance to H. pylori-induced gastritis is unknown. Here, we found that gastric IL-33 mRNA and protein expression were elevated in gastric mucosa of both patients and mice infected with H. pylori, which is positively correlated with bacterial load and the degree of gastritis. IL-33 production was promoted via extracellular regulated protein kinases (ERK) signaling pathway activation by gastric epithelial cells in a cagA-dependent manner during H. pylori infection, and resulted in increased inflammation and bacteria burden within the gastric mucosa. Gastric epithelial cell-derived IL-33 promoted TNF-α production from mast cells in vitro, and IL-33 increased TNF-α production in vivo. Increased TNF-α inhibited gastric epithelial cell proliferation, conducing to the progress of H. pylori-associated gastritis and bacteria colonization. This study defined a patent regulatory networks involving H. pylori, gastric epithelial cell, IL-33, mast cell, and TNF-α, which jointly play a pathological effect within the gastric circumstances. It may be a valuable strategy to restrain this IL-33-dependent pathway in the treatment of H. pylori-associated gastritis.

    A 19-year-old young male presented with abdominal pain and constipation. Subsequent EGD showed nodular gastric mucosa with simple gastric aspirate demonstrating acidic pH of 2.0. The gastric biopsy showed thick subepithelial band of about 15 microns that was confirmed to be collagen on Masson’s trichrome stain along with inflammatory infiltrate. Colonoscopy and capsule endoscopy findings were unremarkable as well as the biopsy of the colon. Collagenous gastritis is a rare histopathological entity characterized by the presence of thick subepithelial collagen band of thickness greater than 10 microns along with intraepithelial lymphocytes and lamina propria lymphoplasmacytic and eosinophilic infitrates. Clinical presentation varies and depends more on the age of the patient with anemia or epigastric pain with nodular gastric mucosa being more common in children while diarrhea being more common in adults due to its increased association with collagenous colitis. The purpose of this case report is; (A) To define the endoscopic and histopathological features and progression of collagenous gastritis in this patient; (B) To compare these findings to those of collagenous sprue and collagenous colitis.

    To evaluate the diagnostic performance of contrast-enhanced ultrasound (CEUS) in differential diagnosis of gastric cancer and gastritis, with histological results as reference standard. From September 2011 to August 2014, 82 patients (50 males and 32 females; mean age ± SD, 59.5 ± 15.0 years; range 19-91 years) with gastric cancer or gastritis were included in this Ethics Committee-approved prospective study. Conventional ultrasonography (US) and CEUS were applied to distinguish the two lesions, and both qualitative and quantitative features were evaluated. Of the 82 histopathologic-proven lesions, 58 were cancer and 24 were gastritis. For US, the gastric wall stratification was not preserved in about one-third of cancer (21/58, 36.2%) compared with gastritis (0/24, 0%) (p < 0.001). Blurred, angular, or spiculated serosa margin and increased echogenicity in perigastric fat appeared only in cancer (10/58, 17.2%), and all of them proved to be pathologic T3 or T4 stage. On CEUS, gastric cancer usually manifested as diffused enhancement without comb-teeth-like vessels (parallel curvilinear structures representing arterial branching within the gastric wall) (56/58, 96.6%), while these vessels presented in most gastritis (19/24, 79.2%, p < 0.001). For quantitative analysis, the malignant lesions showed later and lower enhancement (p < 0.001), and they also had slower speed to reach the peak intensity (p < 0.001). On CEUS, the absence of comb-teeth-like vessel is most reliable for diagnosing malignancy, and the sensitivity, specificity, and accuracy were 96.5%, 79.2%, and 91.5%, respectively. Our results demonstrated the usefulness and accuracy of US and CEUS in differential diagnosis of gastric cancer and gastritis. CEUS has the potential to make the diagnosis more accurate.

    To report a case series of ischemic gastritis and discuss its etiology, management, and associated mortality according to our results and the published English literature. Ischemic gastritis is rare, given the rich blood supply of the stomach. It has been reported in isolated case reports and small case series. Most cases are vascular in origin and associated with a high mortality. Pathology databases from 3 hospitals affiliated with the University of Minnesota Medical School were searched for cases of ischemic gastritis in the last 10 years. Patients' demographics, clinical course, and 1-month and 1-year mortalities were collected from electronic medical records. A total of 12 patients were identified (age range, 32.1 to 83.2), the largest series reported to date. The presenting symptom was gastrointestinal bleeding (8), abdominal pain (2), nausea (1), and symptomatic anemia (1). The etiology included postinterventional radiology embolization (2), hemodynamic changes in the setting of celiac axis stenosis (2), vasculitis (1), systemic hypotension (1), and unknown (6). Treatment included steroid therapy, revascularization by interventional radiology, surgery, or supportive treatment. Thirty-day and 1-year mortalities were 33% and 41%, respectively. Ischemic gastritis is rare, but associated with a high mortality. Evaluation for treatable etiologies should be sought and corrected if present.

    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.

    Disease due to the gastric pathogen Helicobacter pylori varies in severity from asymptomatic to peptic ulcer disease and cancer. Accumulating evidence suggests that one source of this variation is an abnormal host response. The goal of this study was to use a mouse model of H. pylori gastritis to investigate the roles of regulatory T cells (Treg) as well as proinflammatory T cells (Th1 and Th17) in gastritis, gastric T cell engraftment, and gastric cytokine production. Our results support published data indicating that severe gastritis in T cell recipient mice is due to failure of Treg engraftment, that Treg ameliorate gastritis, and that the proinflammatory response is attributable to interactions between several cell subsets and cytokines. We confirmed that gamma interferon (IFN-γ) is essential for induction of gastritis but showed that IFN-γ-producing CD4 T cells are not necessary. Interleukin 17A (IL-17A) also contributed to gastritis, but to a lesser extent than IFN-γ. Tumor necrosis factor alpha (TNF-α) and IL-17F were also elevated in association with disease. These results indicate that while H. pylori-specific CD4+ T cells and IFN-γ are both essential for induction of gastritis due to H. pylori, IFN-γ production by T cells is not essential. It is likely that other proinflammatory cytokines, such as IL-17F and TNF-α, shown to be elevated in this model, also contribute to the induction of disease. We suggest that gastritis due to H. pylori is associated with loss of immunoregulation and alteration of several cytokines and cell subsets and cannot be attributed to a single immune pathway.

    A 70-year-old man with a medical history of rheumatoid arthritis on methotrexate 2.5 mg every other day was being followed for cytomegalovirus (CMV) gastritis and Helicobacter pylori infection, who was also found to have adrenal masses bilaterally. A CT showed a 1 cm left adrenal nodule along with a 2.5 cm right adrenal mass suspicious for malignancy. A positron emission tomography showed metabolic activity in his adrenals that was non-specific (could be seen in benign as well as malignant lesions). The patient was started on valganciclovir 900 mg daily for 30 days. Following treatment the patient showed marked clinical improvement with a weight gain of 9 lbs and a complete resolution of his epigastric pain. A repeat oesophagogastroduodenoscopy performed with biopsy returned negative for CMV. A repeat CT abdomen to assess the adrenals was performed 2 weeks after completion of valganciclovir. His adrenal nodules had decreased significantly in size, with his left adrenal gland nodules measuring 1 cm and now his right adrenal gland nodule measuring 1 cm. PMID:23904414

    The aim and objectives of this study are to identify oral changes in certain gastrointestinal (GI) diseases, namely gastroesophageal reflux disease (GERD), ulcerative colitis, gastritis, and to evaluate these oral symptoms as indicators for assessing GI disorders. In this study, the oral manifestations of various GI disorders were assessed in a varying age group of 250 patients in Government Stanley Medical College and Hospital, Chennai. Out of 250 patients, 142 were affected by GERD, 99 were affected by gastritis, and 9 patients were affected by ulcerative colitis. Of these patients, 177 were males and 73 were females. Evaluation of patients with gastritis revealed that 66.7% affected with gingivitis, 19.2% with dental erosion on the palatal and lingual aspects of maxillary and mandibular teeth predominantly in the anterior region, 10.1% with periodontitis, 2% with gingival erythema. Among the patients with GERD, 44% of the cases showed dental erosion, 25.5% periodontitis, 9.9% gingivitis, 5.7% gingival erythema, 2.8% palatal erythema, 2.1% gingival ulcers, glossitis 2%, 1.4% floor of the mouth erythema, and 0.7% erythema of the tongue. Patients with ulcerative colitis showed 44.4% of gingival erythema, 33.3% of dental erosions, and 22.2% of gingival ulcers and periodontitis. In our study of 250 patients, oral manifestations were observed in 88% of the patients. Both soft tissue and hard tissue changes were evident. There was a high correlation between various GI disease and dental erosion, erythema at various sites of the oral cavity, oral ulcers, gingivitis, periodontitis, and glossitis. Careful evaluation of oral cavity may unveil many GI disorders and help the patient by providing early diagnosis, which further facilitates the prognosis.

    We aimed to identify the signals that indicate the possible benefits of administering Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) at the initiation of meal, compared to immediately after food. This was a randomized, controlled, pilot study in 160 patients who received only NSAIDs for various pain conditions. Patients were randomized to Group I (control group) -NSAID After Food (AF), Group II-NSAID Before Food (BF), Group III-NSAID BF for 2 days and then crossed over to AF for next two days (CO-1) and Group IV-NSAID AF for 2 days and then crossed over to BF for next two days (C0-2 group). Group III & Group IV were given a washout period of 48 hours after the initial two days of treatment. All were followed up for the next 2 drug free days. Patients were observed for the development of gastritis (epigastric distress, epigastric pain, nausea, fullness of stomach, repeated reflux) throughout the study. Symptoms of gastritis were seen in 6.45% (2/31) and 36.11% (13/36) patients in group I and II, respectively. There was no statistically significant difference in the development of gastritis in AF group. However, statistically significant difference (P<0.05) was found between BF group and AF intake of NSAIDs [CO-1 (AF), CO-2 (A.F), AF (control group)] in terms of development of gastritis. Administering NSAIDs at the initiation of meal is better tolerated as indicated by the lower incidence of gastritis. If proved in larger population, routine concurrent administration of medication for prevention of gastritis can be avoided.

    Helicobacter pylori cause damage to gastric epithelial cells and alterations in the p53 gene that lead to cancer development. This study aimed to determine the correlation of p53 expression with H. pylori using immunohistochemistry, RFLP-PCR, and histopathology. Gastric biopsy samples from gastric cancer (GC) (n = 54) and gastritis (n = 31) patients were examined for histopathological changes and expression of p53 protein by immunohistochemistry. Immunohistochemical analysis of p53 protein expression in H. pylori-positive GC sections showed an average of 44.3% positive cells in tumors and 6.9% in normal tissues, as compared to 16.4% and 4.4% in H. pylori-negative sections. P53 expression showed significant association with H. pylori (P = 0.005), invasion depth (P = 0.029) and inflammation reaction (P = 0.008). In gastritis sections, no difference in the average p53 staining in H. pylori-positive or -negative sections was seen. PCR-RFLP results also showed no difference in genotype frequencies of p53 in H. pylori-positive or -negative gastritis sections. Histopathology study of H. pylori-positive GC sections showed that 97.2% were the intestinal type and 2.8% the diffuse type, while in H. pylori-negative sections 35.2% were the intestinal type and 64.8% the diffuse type. Biopsy sections from H. pylori-positive gastritis patients revealed more severe inflammation than those of H. pylori-negative patients. Our results show that H. pylori infection affects p53 expression in GC. The average p53 expression was significantly higher in tumor than in normal tissues. In gastritis sections p53 expression was significantly associated with H. pylori.

    For the last 15 years, infection from Helicobacter pylori (H. pylori) has been recognized in gastritis pathogenesis, and is known to trigger an important inflammatory response in these patients. To determine the association between follicular gastritis and H. pylori infection in children seen at a public hospital in Peru. An analytic, cross-sectional study was conducted on all the children treated at the Hospital Nacional Docente Madre "Niño San Bartolomé" in Lima, Peru, within the time frame of 2011-2012. All the personal data from the patients' medical histories and endoscopic procedures were collected. The crude prevalence ratios (PR) were obtained and adjusted (aPR) with their 95% confidence intervals (95%CI), using generalized linear models with the binomial family and log link function. A total of 123 children met the study criteria. Forty-eight (39%) of the study sample were girls and the mean age of the children was 12 years. H. pylori was present in 44% of the sample and 9% presented with more than 100 bacteria per field (classified as +++). Thirty-five percent of the children had esophagitis due to concomitant reflux. The presence of H. pylori was associated with follicular gastritis (P<0.01; aPR: 2.3; 95% CI:1.49-3.49), adjusted by the children's age. Based on the data analyzed, it was concluded that the children with follicular gastritis had a greater likelihood of having H. pylori than those that did not present with gastritis. These results can be extrapolated to other similar populations and should be evaluated in each setting so that this does not become a public health problem within the next few years.

    Helper T (Th) cell responses are critical for the pathogenesis of Helicobacter pylori-induced gastritis. Th22 cells represent a newly discovered Th cell subset, but their relevance to H. pylori-induced gastritis is unknown. Flow cytometry, real-time PCR and ELISA analyses were performed to examine cell, protein and transcript levels in gastric samples from patients and mice infected with H. pylori. Gastric tissues from interleukin (IL)-22-deficient and wild-type (control) mice were also examined. Tissue inflammation was determined for pro-inflammatory cell infiltration and pro-inflammatory protein production. Gastric epithelial cells and myeloid-derived suppressor cells (MDSC) were isolated, stimulated and/or cultured for Th22 cell function assays. Th22 cells accumulated in gastric mucosa of both patients and mice infected with H. pylori. Th22 cell polarisation was promoted via the production of IL-23 by dendritic cells (DC) during H. pylori infection, and resulted in increased inflammation within the gastric mucosa. This inflammation was characterised by the CXCR2-dependent influx of MDSCs, whose migration was induced via the IL-22-dependent production of CXCL2 by gastric epithelial cells. Under the influence of IL-22, MDSCs, in turn, produced pro-inflammatory proteins, such as S100A8 and S100A9, and suppressed Th1 cell responses, thereby contributing to the development of H. pylori-associated gastritis. This study, therefore, identifies a novel regulatory network involving H. pylori, DCs, Th22 cells, gastric epithelial cells and MDSCs, which collectively exert a pro-inflammatory effect within the gastric microenvironment. Efforts to inhibit this Th22-dependent pathway may therefore prove a valuable strategy in the therapy of H. pylori-associated gastritis. Published by the BMJ Publishing Group Limited.

    Double-contrast upper gastrointestinal barium X-ray radiography (UGI-XR) is the standard gastric cancer screening method in Japan. Atrophic gastritis and enlarged gastric folds are considered the two major features of Helicobacter pylori-induced chronic gastritis, but the clinical meaning of evaluating them by UGI-XR has not been elucidated. We analyzed healthy UGI-XR examinees without a history of gastrectomy, previous Helicobacter pylori eradication and usage of gastric acid suppressants. Of the 6433 subjects, 1936 (30.1 %) had atrophic gastritis and 1253 (19.5 %) had enlarged gastric folds. During the 3-year prospective observational follow-up, gastric cancer developed in seven subjects, six of whom (85.7 %) had atrophic gastritis with H. pylori infection and five of whom (71.4 %) had enlarged gastric folds with H. pylori infection. The Kaplan-Meier method with log-rank testing revealed that both UGI-XR-based atrophic gastritis (p = 0.0011) and enlarged gastric folds (p = 0.0003) are significant predictors for future gastric cancer incidence.

    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. pylorimore » 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.« less

    BACKGROUND: gastric abnormalities are a common feature in patients with primary antibody deficiency. The most important problem is the high incidence of stomach cancer found in these patients. Chronic atrophic gastritis with pernicious anemia is also a common finding that predisposes to gastric adenocarcinoma. The aim of the present study was to identify factors predictive of high risk for developing gastric cancer in patients with primary antibody deficiency. PATIENTS AND METHODS: we studied gastric hormones (gastrin, somatostatin and gastrin-releasing peptide, GRP) in 47 patients (23 children and 24 adults) with primary antibody deficiency. In accordance with the World Health Organization (WHO) classification, patients were diagnosed as having X-linked agammaglobulinemia (Bruton disease) in 13 cases, common variable immunodeficiency in 28, and hypogammaglobulinemia with hyperIgM in 6. Gastric biopsy was performed in 22 patients (16 children and 6 adults). Hormone determinations were carried out by radioimmunoassay. RESULTS: baseline serum gastrin levels were normal or increased compared with controls, but the response to stimulation with a hyperproteic diet was delayed in 18 patients and lower than in controls in 7. In 4 adult patients, all with pernicious anemia, gastric biopsy revealed chronic atrophic gastritis involving the stomach corpus and antrum (type B gastritis). The absence of a normal response of gastrin secretion to stimulation with a hyperproteic diet may be explained by this finding. Serum somatostatin and GRP levels were higher than in controls. No correlations were found between these findings and patient age, type of immunodeficiency or duration of clinical manifestations.

    Background Infection with Helicobacter pylori triggers a chronic gastric inflammation that can progress to atrophy and gastric adenocarcinoma. Polarization of macrophages is a characteristic of both cancer and infection, and may promote progression or resolution of disease. However, the role of macrophages and their polarization during H. pylori infection has not been well defined. Methodology/Principal Findings By using a mouse model of infection and gastric biopsies from 29 individuals, we have analyzed macrophage recruitment and polarization during H. pylori infection by flow cytometry and real-time PCR. We found a sequential recruitment of neutrophils, eosinophils and macrophages to the gastric mucosa of infected mice. Gene expression analysis of stomach tissue and sorted macrophages revealed that gastric macrophages were polarized to M1 after H. pylori infection, and this process was substantially accelerated by prior vaccination. Human H. pylori infection was characterized by a mixed M1/M2 polarization of macrophages. However, in H. pylori-associated atrophic gastritis, the expression of inducible nitric oxide synthase was markedly increased compared to uncomplicated gastritis, indicative of an enhanced M1 macrophage polarization in this pre-malignant lesion. Conclusions/Significance These results show that vaccination of mice against H. pylori amplifies M1 polarization of gastric macrophages, and that a similar enhanced M1 polarization is present in human H. pylori-induced atrophic gastritis.

    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.

    Collagenous gastritis is a distinctive disorder characterized by thickening of the subepithelial collagen layer in the gastric mucosa. Although this entity was recognized in 1989, its etiology, pathogenesis, and clinicopathologic features remain poorly understood because of its rarity. An unusual case of collagenous gastritis was observed in a 37-year-old man who presented with profound weight loss, a feature that has not previously been emphasized.

    Aim: This study was aimed to investigate the presence of H. pylori and its virulence genotypes in dental plaques of Iranian patients with chronic periodontitis. Background: Helicobacter pylori is a Gram-negative bacterium that is associated with atrophic gastritis, peptic ulcer, and gastric cancer. Several studies have detected this bacterium in the oral cavity, suggesting it as a potential reservoir. Methods: A hundred individuals were divided in 2 groups: 50 patients with chronic periodontitis (case group), and 50 subjects in non-periodontitis (control group). Supragingival and subgingival plaque samples were collected from the individuals using wood wedges and sterile paper points respectively, and prepared for PCR analysis. Results: Totally, H. pylori DNA was detected in 5 out of 100 (5%) dental plaques. Of 5 dental plaques positive for H. pylori, cagA gene was detected in 4 specimen, 3 in periodontitis group and one in non-periodontitis group. The H. pylori vacA s1m1 genotype was predominantly detected in 2/5 samples. The babA2 gene was detected in all (5/5) H. pylori-positive dental plaques. There was no significant correlation between the presence of H. pylori genotypes from dental plaques and chronic periodontitis (P > 0.05). Conclusion: Our results revealed that the rate of H. pylori is very low in the dental plaques of Iranian patients with chronic periodontitis. Majority of H. pylori strains from oral cavity were highly virulent based on the main clinically virulence factors they carried. PMID:29511475

    Objectives: Circulating autoantibodies targeting the H+/K+-ATPase proton pump of gastric parietal cells are considered markers of autoimmune gastritis, whose diagnostic accuracy in atrophic body gastritis, the pathological lesion of autoimmune gastritis, remains unknown. This study aimed to assess autoantibodies against ATP4A and ATP4B subunits of parietal cells H+, K+-ATPase in atrophic body gastritis patients and controls. Methods: One-hundred and four cases with atrophic body gastritis and 205 controls were assessed for serological autoantibodies specific for ATP4A or ATP4B subunits using luminescent immunoprecipitation system (LIPS). Recombinant luciferase-reporter-fused-antigens were expressed by in vitro transcription-translation (ATP4A) or after transfection in Expi293F cells (ATP4B), incubated with test sera, and immune complexes recovered using protein-A-sepharose. LIPS assays were compared with a commercial enzyme immunoassay (EIA) for parietal cell autoantibodies. Results: ATP4A and ATP4B autoantibody titers were higher in cases compared to controls (P<0.0001). The area under the receiver-operating characteristic curve was 0.98 (95% CI 0.965–0.996) for ATP4A, and 0.99 (95% CI 0.979–1.000) for ATP4B, both higher as compared with that of EIA: 0.86 (95% CI 0.809–0.896), P<0.0001. Sensitivity-specificity were 100–89% for ATP4A and 100–90% for ATP4B assay. Compared with LIPS, EIA for parietal cell autoantibodies showed a lower sensitivity (72%, P<0.0001) at a similar specificity (92%, P=0.558). Conclusions: Positivity to both, ATP4A and ATP4B autoantibodies is closely associated with atrophic body gastritis. Both assays had the highest sensitivity, at the cost of diagnostic accuracy (89 and 90% specificity), outperforming traditional EIA. Once validated, these LIPS assays should be valuable screening tools for detecting biomarkers of damaged atrophic oxyntic mucosa. PMID:28102858

    Traditionally, Helicobacter infection is considered to be the most common cause of gastritis. In the cross-sectional Central European histoGERD trial, we assessed the prevalence of different types of gastritis, correlating histological and endoscopic diagnoses. A total of 1123 individuals participated in an observational multicentre study. Endoscopists classified individuals as positive or negative for gastritis and rendered the putative cause. Pathologists evaluated biopsy specimens based upon the Updated Sydney System. Histological diagnosis of gastritis was made in 639 (56.9%) participants. In all, 210 (18.7%) individuals were diagnosed with Helicobacter gastritis, 215 (19.1%) with post Helicobacter gastritis, 234 (20.8%) with reactive gastropathy, 26 (2.3%) with autoimmune gastritis, and 6 (0.5%) with focally enhanced gastritis related to Crohn's disease. In 46 out of 639 (7.2%) individuals diagnosed with gastritis, combinations of different histological subtypes were noted the most common being reactive gastropathy and post Helicobacter gastritis. Endoscopic diagnosis of gastritis was made in 534 (47.6%) individuals. Reactive gastropathy was more common than active Helicobacter gastritis, and the majority of cases attributable to Helicobacter infection were no longer ongoing, i.e. post Helicobacter gastritis. Agreement between histological and endoscopic diagnoses was better in reactive gastropathy than in Helicobacter gastritis. Copyright © 2014 Editrice Gastroenterologica Italiana S.r.l.

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.

    The routine use of special stains for detection of Helicobacter remains controversial. To determine the frequency of histologically atypical Helicobacter infection. All gastric biopsies received at a large pathology reference laboratory over a 6-month period were stained for Helicobacter, and the histologic and clinicopathologic parameters evaluated. Amongst 7663 Helicobacter-positive biopsies, 823 (10.7%) did not show typical chronic active gastritis with numerous Helicobacter organisms, and were therefore considered histologically atypical. Rare Helicobacter pylori organisms accounted for 58.0% of all atypical infections; the next most common atypical Helicobacter infection was that with minimal or no gastric inflammation (23.3% of atypical infections). Patients in these groups did not differ demographically from those with other forms of atypical or typical Helicobacter infection, although a small subgroup (6%) was more likely to have had a previously treated infection. In many of these atypical infections, Helicobacter would not have been suspected based on the histologic findings alone, and would have been missed without routine special stains. Performing a sensitive stain could prevent additional testing and allow prompt treatment of the affected patients, thus substantially reducing the risk for peptic ulcer and gastric cancer and preventing the transmission of the infection to family members.

H. pylori chronic gastritis, slowly progresses to atrophic gastritis, in the majority of patients; in a few patients, with genetic susceptibility to form intrinsic factor antibody, it progresses to pernicious anaemia. In majority of patients of pernicious anaemia, H. pylori gradually disappears from the gastric mucosa, on development of intestinal metaplasia in them. Atrophic gastritis results from H. pylori or non H. pylori. H. pylori infection is diagnosed in the presence of H. pylori in the gastric mucosal biopsy and/or H. pylori antibody (IgG) in the serum. The presence of the genetic factor (intrinsic factor antibody) is essential for the diagnosis of pernicious aneamia. Pernicious anaemia patients without intrinsic factor antibody, should be correctly diagnosed as atrophic gastritis, in view of the absence of the genetic factor (intrinsic factor antibody) in them.

    Apigenin, one of the most common flavonoids, is abundant in celery, parsley, chamomile, passionflower, and other vegetables and fruits. Celery is recognized as a medicinal vegetable in Oriental countries to traditionally treat inflammation, swelling, blood pressure, serum lipid, and toothache. In this study, we investigated apigenin treatment effects on Helicobacter pylori-induced atrophic gastritis and gastric cancer progression in Mongolian gerbils. Five to eight-week-old Mongolian gerbils were inoculated with Helicobacter pylori for four weeks without (atrophic gastritis group) or with N'-methyl-N'-nitro-N-nitroso-guanidine (MNNG) (gastric cancer group) in drinking water, and were then rested for two weeks. During the 7th-32th (atrophic gastritis group) or the 7th-52th (gastric cancer group) weeks, they were given various doses (0-60 mg/kgbw/day) of apigenin. At the end of the 32th (atrophic gastritis group) or the 52th (atrophic gastritis group) week, all Mongolian gerbils were sacrificed using the CO2 asphyxia method. The histological changes of Helicobacter pylori colonization, neutrophil and monocyte infiltrations, and atrophic gastritis in both atrophic gastritis and gastric cancer Mongolian gerbils were examined using immunohistochemistry stain and Sydney System scoring. Apigenin treatments (30-60 mg/kgbw/day) effectively decreased atrophic gastritis (atrophic gastritis group) and dysplasia/gastric cancer (gastric cancer group) rates in Mongolian gerbils. Apigenin treatment (60 mg/kgbw/day) significantly decreased Helicobacter pylori colonization and Helicobacter pylori-induced histological changes of neutrophil and monocyte infiltrations and atrophic gastritis in both atrophic gastritis and gastric cancer Mongolian gerbils. Apigenin has the remarkable ability to inhibit Helicobacter pylori-induced atrophic gastritis and gastric cancer progression as well as possessing potent anti-gastric cancer activity.

    Helicobacter pylori infection is associated with gastritis, peptic ulcer disease and gastric carcinoma. The severity of damage is determined by the interplay between environmental/behavioral factors, bacterial pathogenicity genes and host genetic polymorphisms that can influence the secretion levels of inflammatory cytokines. Accordingly, this study aimed to identify polymorphisms in the IL-1B and IL-1RN genes and their associations with H. pylori infection, cagA gene of H. pylori, and gastroduodenal diseases. Gastric biopsy samples from 151 patients infected with H. pylori and 76 uninfected individuals were analyzed. H. pylori infection was diagnosed by histology and PCR. Polymorphisms at positions -511, -31 and +3954 of the IL-1B gene were detected by PCR-RFLP, and an analysis of the VNTR polymorphism of the IL-1RN gene was performed by PCR. It was observed that the presence of the T/T genotype at position -511 and the C/C genotype at position -31 were associated with H. pylori infection and with an increased risk of gastritis in H. pylori-positive patients. Additionally, strains from patients H. pylori-positive carrying the cagA gene was significantly related with the T/T genotype at position -511 of IL-1B.  No association of polymorphisms at position +3954 of IL-1B and in the IL-1RN with H. pylori infection and with risk of severe gastric diseases was found. We demonstrated that polymorphisms in the promoter region of the IL-1B gene (at positions -511 and -31) are associated with an enhanced risk of H. pylori infection as well as gastritis in H. pylori-positive patients.

    As atrophic gastritis and intestinal metaplasia as a result of Helicobacter pylori are considered risk factors for gastric cancer, it is important to assess their severity. In the West, the operative link for gastritis assessment (OLGA) and operative link for gastric intestinal metaplasia assessment (OLGIM) staging systems based on biopsy have been widely adopted. In Japan, however, narrow-band imaging (NBI)-magnifying endoscopic diagnosis of gastric mucosal inflammation, atrophy, and intestinal metaplasia has been reported to be fairly accurate. Therefore, we investigated the practicality of NBI-magnifying endoscopy (NBI-ME) for gastritis staging. We enrolled 55 patients, in whom NBI-ME was used to score the lesser curvature of the antrum (antrum) and the lesser curvature of the lower body (corpus). The NBI-ME score classification was established from images obtained beforehand, and then biopsy specimens taken from the observed areas were scored according to histological findings. The NBI-ME and histology scores were then compared. Furthermore, we assessed the NBI-ME and histology stages using a combination of scores for the antrum and corpus, and divided the stages into two risk groups: low and high. The degree to which the stage assessed by NBI-ME approximated that assessed by histology was then ascertained. Degree of correspondence between the NBI-ME and histology scores was 69.1% for the antrum and 72.7% for the corpus, and that between the high- and low-risk groups was 89.1%. Staging of gastritis using NBI-ME approximates that based on histology, and would be a practical alternative to the latter. © 2015 The Authors.

    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

    Indirect evidence suggests that the parietal cell antibody circulating in the serum of pernicious anaemia patients is a complement fixing antibody. In this work, we have presented direct evidence using an immunofluorescent technique, that the antigen–antibody union occurring in the gastric mucosa between this antibody and the parietal cell antigen binds complement (C'). We have further adduced data to indicate that serum C' activity was decreased in more than one-third of our patients with pernicious anaemia and in one-fourth of those with advanced atrophic gastritis. Eighty-five per cent of the patients with lowered serum C' had parietal cell antibody in the serum and some of them also had intrinsic factor antibody. These findings support the concept of the autoimmune mechanism in the development of the gastric atrophic lesion in a proportion of patients with pernicious anaemia and atrophic gastritis. This mechanism includes the participation of complement in the antigen–antibody reaction at the parietal cell level. ImagesFIG. 1FIG. 2 PMID:4905403

    Autoimmune gastritis (AIG) may predispose to gastric carcinoid tumors or adenocarcinomas and may also cause unexplained iron and/or vitamin B(12) deficiency. The aims of this study were to explore clinical manifestations, endoscopic findings and laboratory features of patients with AIG. 109 patients with AIG were enrolled into the study. In addition to demographic and clinical data, gastric lesions, serum gastrin, vitamin B(12), antiparietal cell antibody (APA), current Helicobacter pylori status, and anti-H. pylori IgG were also investigated. The mean age of the patients was 53.06 ± 12.7 years (range 24-81; 72 (66.1%) women). The most common main presenting symptom was abdominal symptoms in 51 patients, consultation for iron and/or vitamin B(12) deficiency in 36, and non-specific symptoms including intermittent diarrhea in 15 patients. Endoscopic lesions were detected in 17 patients, hyperplastic polyps in 8, gastric carcinoid tumor in 4, fundic gland polyps in 3, and adenomatous polyps in 2 patients. H. pylori was negative in all patients in biopsy specimens; however, anti-H. pylori IgG was positive in 30 (27.5%) patients. 91 patients (83.4%) were positive for APA. In patients with AIG, the main symptoms prompted for clinical investigation were: abdominal symptoms, iron/B(12) deficiency and non-specific symptoms. 20% of patients with AIG had various gastric lesions including type I gastric carcinoids. None of the patients were positive for H. pylori by means of invasive tests; however, anti-H. pylori IgG was found in 27.5% of patients. Patients referring with non-specific abdominal symptoms such as bloating, diarrhea and iron/B(12) deficiency should be investigated for the presence of AIG. Copyright © 2012 S. Karger AG, Basel.

    Background and Aim. Although many epidemiologic studies have shown that Helicobacter pylori eradication has prophylactic effects on gastric cancer, it does not completely eliminate the risk of gastric cancer. We aimed to investigate the changes in histological gastritis in patients receiving rebamipide treatment after H. pylori eradication. Methods. 206 patients who had undergone H. pylori eradication were evaluated. Of these, 169 patients who achieved successful eradication were randomly allocated to 2 groups: the rebamipide group (n = 82) and the untreated group (n = 87). The primary endpoints were histopathological findings according to the updated Sydney system at the start of the study and after 1 year. Results. Final assessment for histological gastritis was possible in 50 cases from the rebamipide group and 53 cases from the untreated group. The activity and atrophy improved in both the rebamipide and untreated groups, and no significant intergroup differences were observed. Chronic inflammation affecting the lesser curvature of the corpus was significantly improved in the rebamipide group compared to in the untreated group (1.12 ± 0.08 versus 1.35 ± 0.08; P = 0.043). Conclusions. Rebamipide treatment after H. pylori eradication alleviated chronic inflammation in the lesser curvature of the corpus compared to that in the untreated group. This trial is registered with UMIN000002369. PMID:26060821

    AIM: To measure biochemical parameters in stomach biopsies and test their suitability as diagnostic biomarkers for gastritis and precancerous lesions. METHODS: Biopsies were obtained from the stomachs of two groups of patients (n = 40) undergoing fiber-optic endoscopy due to upper gastrointestinal symptoms. In the first group (n = 17), only the corpus region was examined. Biopsies were processed for microscopic examination and measurement of mitochondrial O2 consumption (cellular respiration), cellular adenosine triphosphate (ATP), glutathione (GSH), and caspase activity. In the second group of patients (n = 23), both corpus and antral regions were studied. Some biopsies were processed for microscopic examination, while the others were used for measurements of cellular respiration and GSH level. RESULTS: Microscopic examinations of gastric corpus biopsies from 17 patients revealed normal mucosae in 8 patients, superficial gastritis in 7 patients, and chronic atrophic gastritis in 1 patient. In patients with normal histology, the rate (mean ± SD) of cellular respiration was 0.17 ± 0.02 μmol/L O2 min-1 mg-1, ATP content was 487 ± 493 pmol/mg, and GSH was 469 ± 98 pmol/mg. Caspase activity was detected in 3 out of 8 specimens. The values of ATP and caspase activity were highly variable. The presence of superficial gastritis had insignificant effects on the measured biomarkers. In the patient with atrophic gastritis, cellular respiration was high and ATP was relatively low, suggesting uncoupling oxidative phosphorylation. In the second cohort of patients, the examined biopsies showed either normal or superficial gastritis. The rate of cellular respiration (O2. μmol/L min-1 mg-1) was slightly higher in the corpus than the antrum (0.18 ± 0.05 vs 0.15 ± 0.04, P = 0.019). The value of GSH was about the same in both tissues (310 ± 135 vs 322 ± 155, P = 0.692). CONCLUSION: The corpus mucosa was metabolically more active than the antrum tissue. The data in this

    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. (c) 2008 Wiley-Liss, Inc.

    In select Helicobacter pylori-infected populations with low gastric cancer, nematode coinfections are common and both helicobacter gastritis and filariasis are modeled in gerbils. We evaluated gastritis, worm counts, tissue cytokine gene expression levels and Th1/Th2-associated antibody responses in H. pylori and Brugia pahangi mono- and coinfected gerbils. H. pylori-associated gastritis indices were significantly lower 21 weeks post-infection in coinfected gerbils (p ≤ 0.05) and were inversely proportional to worm counts (r2 = −0.62, p < 0.003). Additionally, IFN-γ, IL-1β, CXCL1, IL-4 and IL-10 mRNA levels in the gastric antrum reflected a significant host response to gastric H. pylori and as well as systemic filariasis (p ≤ 0.05). Despite increasing worm burden (p < 0.05), gastritis progressed in coinfected gerbils (p < 0.03) becoming equivalent to H. pylori-infected gerbils at 42 weeks (p = 0.7). Pro- and anti-inflammatory mediator mRNA levels were notably downregulated in B. pahangi infected gerbils below uninfected control values, suggesting hyporesponsiveness to B. pahangi. Consistent with an increasing Th1 response to H. pylori, IgG2a (p < 0.01), IL-1β (p = 0.04) and CXCL1 (p = 0.006) responses significantly increased and IL-4 (p = 0.05) and IL-10 (p = 0.04) were decreased in coinfected gerbils at 42 weeks. Initial systemic responses to B. pahangi resulted in attenuated gastritis in coinfected gerbils, but subsequent filarid-associated hyporesponsiveness appears to have promoted H. pylori gastritis.

    As nonmicrobial dietary approach is capable of controlling Helicobacter pylori infection, we evaluated the efficacy of long-term dietary administration of Artemisia and/or green tea extracts on H. pylori-initiated, high-salt-promoted chronic atrophic gastritis and gastric tumorigenesis mouse model. Helicobacter pylori-infected and high-salt-diet-administered C57BL/6 mice were administered with Artemisia extracts (MP group) and/or green tea extracts (GT group) for 36 weeks in addition to the control group (ES group, gastroprotective drug, ecabet sodium 30 mg/kg, diet pellet). Gross and pathological gastric lesions were evaluated after 24 and 36 weeks, respectively, and their underlying molecular changes were measured in gastric homogenates. Detailed mechanisms were further evaluated in in vitro cell models. The erythematous and nodular changes and mucosal ulcerative and erosive lesions were noted in the control group at 24 weeks. MP, GT, MPGT, and ES groups all showed significantly ameliorated pathologic lesion compared to the control group (p < .05). After the 36 weeks, scattered nodular masses with some central ulcers and thin gastric surface were noted in the control stomach, whereas no tumorous lesion and milder atrophic changes were observed in all MP, GT, and MPGT groups except ES group (p < .05). On molecular analysis, increased expressions of COX-2, TNF-α, IL-6, lipid peroxide, and activated STAT3 relevant to H. pylori infection were significantly decreased with MPGT administration (p < .01), whereas HSP70 was significantly increased. PGDH expressions, core tumor suppressor involved in carcinogenesis, were significantly decreased with H. pylori infection (p < .05), but significantly increased in MPGT group (p < .05). Increased mucosal apoptotic index noted in the control group was significantly decreased with MP and/or GT along with significantly preserved gastric gastroprotective mediators (p < .01) such as mucins, HSP27, and HSP70.

    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.

    Gastritis is preponderantly characterized by inflammation of the lining epithelial layer and the chronic gastritis is considered as a pre-cancer lesion. For many centuries olive (Olea europaea) leaf has been used for its putative health potential, nonetheless, to date, the gastroprotective effects of olive leaves have not been studied yet. Hence, in this study we investigated whether olive leaf extract (OLE) could protect gastric mucosa against HCl/ethanol-induced gastric mucosal damage in rats. Hcl/ethanol administration caused significant damage to the gastric mucosa, as confirmed by gastric ulcer index and histological evaluation. However, this damage was largely prevented by pre-administering 20mg/kg omeprazole or 100mg/kg OLE. Interestingly, the damage was completely prevented by pre-administering 200 and 300mg/kg OLE. Moreover, OLE attenuated the inflammatory response by decreasing nuclear factor-κB (NF-κB), cycloxygenase-2 (COX-2) and tumor necrosis factor-α (TNF-α) expressions, and down-regulating inducible nitric oxide synthase (iNOS) and interleukin-1β (IL-1β) in gastric mucosa. The gastroprotective mechanism of OLE involved the promotion of enzymatic and nonenzymatic molecules (superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase and glutathione reduced form), promoting nuclear factor erythroid 2-related factor 2 (Nrf2) mRNA expression, halting lipid peroxidation and preventing the overproduction of nitric oxide. Together, our findings clearly demonstrated that OLE could prevent HCl/ethanol-induced gastritis by attenuating inflammation and oxidant/antioxidant imbalance. Indeed, OLE could potentially be useful as a natural therapy for gastritis. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

    Double-contrast upper gastrointestinal barium X-ray radiography (UGI-XR) is one of the most widely conducted gastric cancer screening methods. It has been executed to find gastric cancer, but has not been usually executed to detect premalignant atrophic mucosa of stomach. To understand the meaning of UGI-XR-based atrophic gastritis, we analyzed its association with several causative factors including Helicobacter pylori (HP) infection. We evaluated 6,901 healthy adults in Japan. UGI-XR-based atrophic gastritis was diagnosed based on the irregular shape of areae gastricae and its expansion in the stomach. Of the 6,433 subjects with no history of HP eradication and free from gastric acid suppressants, 1,936 were diagnosed as UGI-XR-based atrophic gastritis (mild: 234, moderate: 822, severe: 880). These were univariately associated with serum HP IgG and serum pepsinogen I/II ratio with statistical significance. The multiple logistic analysis calculating standardized coefficients (β) and odds ratio (OR) demonstrated that serum HP IgG (β = 1.499, OR = 4.48), current smoking (β = 0.526, OR = 1.69), age (β = 0.401, OR = 1.49), low serum pepsinogen I/II ratio (β = 0.339, OR = 1.40), and male gender (β = 0.306, OR = 1.36) showed significant positive association with UGI-XR-based atrophic gastritis whereas drinking and body mass index did not. Among the age/sex/smoking/drinking-matched 227 pairs derived from chronically HP-infected and successfully HP-eradicated subjects, UGI-XR-based atrophic gastritis was detected in 99.1% of the former but in only 59.5% of the latter subjects (p<0.0001). Contrastively, UGI-XR-based atrophic gastritis was detected in 13 of 14 HP-positive proton pump inhibitor users (92.9%) and 33 of 34 HP-positive histamine H2-receptor antagonist users (97.1%), which are not significantly different from gastric acid suppressant-free subjects. The presence of UGI-XR-based atrophic gastritis is positively

    Switching of cellular energy production from oxidative phosphorylation (OXPHOS) by mitochondria to aerobic glycolysis occurs in many types of tumors. However, the significance of this switching for the development of gastric carcinoma and what connection it may have to Helicobacter pylori infection of the gut, a primary cause of gastric cancer, are poorly understood. Therefore, we investigated the expression of OXPHOS complexes in two types of human gastric carcinomas ("intestinal" and "diffuse"), bacterial gastritis with and without metaplasia, and chemically induced gastritis by using immunohistochemistry. Furthermore, we analyzed the effect of HP infection on several key mitochondrial proteins. Complex I expression was significantly reduced in intestinal type (but not diffuse) gastric carcinomas compared to adjacent control tissue, and the reduction was independent of HP infection. Significantly, higher complex I and complex II expression was present in large tumors. Furthermore, higher complex II and complex III protein levels were also obvious in grade 3 versus grade 2. No differences of OXPHOS complexes and markers of mitochondrial biogenesis were found between bacterially caused and chemically induced gastritis. Thus, intestinal gastric carcinomas, but not precancerous stages, are frequently characterized by loss of complex I, and this pathophysiology occurs independently of HP infection.

    To evaluate the association between Helicobacter pylori (H. pylori) infection and MLH1 and MGMT methylation and its relationship with microsatellite instability (MSI). The methylation status of the MLH1 and MGMT promoter region was analysed by methylation specific methylation-polymerase chain reaction (MSP-PCR) in gastric biopsy samples from uninfected or H. pylori-infected children (n = 50), from adults with chronic gastritis (n = 97) and from adults with gastric cancer (n = 92). MLH1 and MGMT mRNA expression were measured by real-time PCR and normalised to a constitutive gene (β actin). MSI analysis was performed by screening MSI markers at 4 loci (Bat-25, Bat-26, D17S250 and D2S123) with PCR; PCR products were analysed by single strand conformation polymorphism followed by silver staining. Statistical analyses were performed with either the χ(2) test with Yates continuity correction or Fisher's exact test, and statistical significance for expression analysis was assessed using an unpaired Student's t-test. Methylation was not detected in the promoter regions of MLH1 and MGMT in gastric biopsy samples from children, regardless of H. pylori infection status. The MGMT promoter was methylated in 51% of chronic gastritis adult patients and was associated with H. pylori infection (P < 0.05); this region was methylated in 66% of gastric cancer patients, and the difference in the percentage of methylated samples between these patients and those from H. pylori-infected chronic gastritis patients was statistically significant (P < 0.05). MLH1 methylation frequencies among H. pylori-infected and non-infected chronic gastritis adult patients were 13% and 7%, respectively. We observed methylation of the MLH1 promoter (39%) and increased MSI levels (68%) in samples from gastric cancer patients in comparison to samples from H. pylori-infected adult chronic gastritis patients (P < 0.001 and P < 0.01, respectively). The frequency of promoter methylation for both genes was

    Phlegmonous gastritis (PG) is a rare, acute, severe infectious disease of the gastric wall that is often fatal due to Streptococcus spp. A 77-year-old man with diabetes and a gastric ulcer was urgently admitted due to prolonged nausea and vomiting. Computed tomography revealed widespread diffuse thickening of the gastric wall, and PG was suspected. The patient expired less than 9 hours after admission despite intensive treatments. Later, an analysis of the blood and gastric juice revealed group A streptococcus (GAS) and virulence factors associated with toxic shock syndrome (TSS). We herein diagnosed a patient with an extremely aggressive course of PG caused by GAS TSS.

    Helicobacter pylori (H. pylori) is involved in the pathogenesis of gastric inflammatory disorders. Both antral chronic gastritis and H. pylori infection prevalence increase with age. The aim of the study was to assess the prevalence of H. pylori infection in young adults and to study the relationship between endoscopical and histological features and H. pylori infection. The study concerned 547 young patients (age: 18-25 years), undergoing endoscopy for upper gastrointestinal symptoms. The severity and the activity of chronic gastritis was graded by histological examination of antral biopsies. The diagnosis of H. pylori infection was based on histology and culture or urease test. Fifty-three percent of the patients had a normal endoscopy; 44 ulcers were found: 34 duodenal ulcers and 10 gastric ulcers. H. pylori infection was detected in 34% of cases. The prevalence of H. pylori infection was 29.8% in non-ulcer patients, 50% in gastric ulcers and 91% in duodenal ulcers (P < 0.01). Duodenal ulcer, aspect of antral mosaic mucosa and nodular gastritis, were closely related to the presence of H. pylori. There was a significant relationship between H. pylori infection and both the severity (P < 0.01) and the activity (P < 0.01) of the antral chronic gastritis. The prevalence of follicular gastritis was 22% : it was present in 60% of H. pylori positive patients and 2.4% of H. pylori negative patients. H. pylori infection was more frequent in patients from Africa than in Europeans (P < 0.01). There was no significant association between H. pylori infection and different types of diets, settlements (rural vs urban) or symptoms. These results show that in the young population studied, duodenal ulcer, nodular gastritis, antral mosaic mucosa, active chronic gastric and follicular gastritis are closely related to H. pylori infection. They suggest that in the subgroup of non ulcer symptomatic patients, H. pylori prevalence is higher than in the general population.

    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.

    Chronic atrophic gastritis (CAG) is the precancerous stage of gastric carcinoma. Traditional Chinese Medicine (TCM) has been widely used in treating CAG. This study aimed to reveal core pathogenesis of CAG by validating the TCM syndrome patterns and provide evidence for optimization of treatment strategies. This is a cross-sectional study conducted in 4 hospitals in China. Hierarchical clustering analysis (HCA) and complex system entropy clustering analysis (CSECA) were performed, respectively, to achieve syndrome pattern validation. Based on HCA, 15 common factors were assigned to 6 syndrome patterns: liver depression and spleen deficiency and blood stasis in the stomach collateral, internal harassment of phlegm-heat and blood stasis in the stomach collateral, phlegm-turbidity internal obstruction, spleen yang deficiency, internal harassment of phlegm-heat and spleen deficiency, and spleen qi deficiency. By CSECA, 22 common factors were assigned to 7 syndrome patterns: qi deficiency, qi stagnation, blood stasis, phlegm turbidity, heat, yang deficiency, and yin deficiency. Combination of qi deficiency, qi stagnation, blood stasis, phlegm turbidity, heat, yang deficiency, and yin deficiency may play a crucial role in CAG pathogenesis. In accord with this, treatment strategies by TCM herbal prescriptions should be targeted to regulating qi, activating blood, resolving turbidity, clearing heat, removing toxin, nourishing yin, and warming yang. Further explorations are needed to verify and expand the current conclusions.

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

    The Mongolian gerbil model of Helicobacter pylori infection resembles human gastritis. In this study, we investigated the role of NF-κB activation in H. pylori-infected gerbils. Activated macrophages were significantly increased in H. pylori-infected gastric mucosa and were identified as being important cells with potent activation of NF-κB, which plays an important part in producing proinflammatory cytokines. Macrophage depletion by the administration of clodronate resulted in milder inflammation in gerbils infected with H. pylori. In macrophages, the inhibition of IκB kinase β (IKKβ), which is a critical kinase for NF-κB activation, resulted in lower proinflammatory cytokine expression caused by heat-killed H. pylori cells. Furthermore, treatment with IKKβ inhibitor resulted in milder inflammation in gerbils with H. pylori gastritis. Collectively, our data suggest that H. pylori-mediated gastric inflammation critically depends on the efficient recruitment and activation of macrophages, with sufficient NF-κB activation.

    Autoimmune gastritis (AIG) is a gastric pathologic condition affecting the mucosa of the fundus and the body and eventually leading to hypo-achlorhydria. We report our clinical and pathological experience with AIG. Data from patients with a diagnosis of AIG seen in the period January 2002-December 2012 were retrieved. Only patients with complete sets of biopsies were analyzed. Data from 138 patients were available for analysis. Pernicious anemia was present in 25% of patients, iron deficiency anemia was found in 29.7% of patients, hypothyroidism in 23% of patients, type 1 diabetes in 7.9% of patients, and vitiligo in 2.8% of patients. Parietal cell antibodies were positive in 65% of patients, and no patient had serology positive for celiac disease. All gastric biopsies showed glandular atrophy associated with enterochromaffin-like (ECL)-cells hyperplasia, features limited to the mucosa of the fundus and body, and focal glandular intestinal metaplasia. Helicobacter pylori was negative in all cases. AIG was strongly associated with anemia; atrophy, intestinal metaplasia and ECL hyperplasia in the gastric fundus and body are hallmarks of this condition.

    Switching of cellular energy production from oxidative phosphorylation (OXPHOS) by mitochondria to aerobic glycolysis occurs in many types of tumors. However, the significance of this switching for the development of gastric carcinoma and what connection it may have to Helicobacter pylori infection of the gut, a primary cause of gastric cancer, are poorly understood. Therefore, we investigated the expression of OXPHOS complexes in two types of human gastric carcinomas (“intestinal” and “diffuse”), bacterial gastritis with and without metaplasia, and chemically induced gastritis by using immunohistochemistry. Furthermore, we analyzed the effect of HP infection on several key mitochondrial proteins.

    Cold hypersensitivity in the hands and feet (CHHF) is a common symptom in Korea and patients with CHHF complain of coldness in the hands and feet in an environment that is not considered cold by unaffected people. In traditional East Asian medicine, CHHF is believed to be accompanied by various diseases and symptoms, and is considered a symptom that needs active treatment. CHHF is used for pattern identification in the cold pattern, yang deficiency, and constitution. This study aimed to examine the differences in frequencies of chronic diseases with respect to the presence of CHHF. Disease history, CHHF, body measurements, and blood test survey data from 6149 patients collected by 25 medical institutes in Korea were obtained from the Korean Medicine Data Center. The participants were divided into CHHF (n = 1909) and non-CHHF groups (n = 3017) according to the CHHF survey. The differences in frequencies of 18 diseases were analysed using chi-square tests, and the odds ratios (ORs) for each disease according to CHHF status were examined via logistic regression with adjustment for age, sex, and body mass index (BMI). Based on chi-square test results, the CHHF group showed a higher frequency of the following diseases: anaemia, hypotension, chronic gastritis, reflux oesophagitis, chronic rhinitis, dysmenorrhoea, and gastroduodenal ulcer. Diseases found in lower frequencies were as follows: hypertension, diabetes mellitus, impaired fasting glucose, dyslipidaemia, stroke, fatty liver, and angina pectoris. In addition, from the logistic regression with adjustment for age, sex, and BMI, the CHHF group showed a lower OR in diabetes mellitus and dyslipidaemia than the non-CHHF group, but a higher OR in degenerative arthritis, chronic gastritis, gastroduodenal ulcer, reflux oesophagitis, and chronic rhinitis. This study showed that CHHF is associated with chronic disease. Further large-scale prospective studies are needed to validate these associations.

    Background Double-contrast upper gastrointestinal barium X-ray radiography (UGI-XR) is one of the most widely conducted gastric cancer screening methods. It has been executed to find gastric cancer, but has not been usually executed to detect premalignant atrophic mucosa of stomach. To understand the meaning of UGI-XR-based atrophic gastritis, we analyzed its association with several causative factors including Helicobacter pylori (HP) infection. Methods We evaluated 6,901 healthy adults in Japan. UGI-XR-based atrophic gastritis was diagnosed based on the irregular shape of areae gastricae and its expansion in the stomach. Results Of the 6,433 subjects with no history of HP eradication and free from gastric acid suppressants, 1,936 were diagnosed as UGI-XR-based atrophic gastritis (mild: 234, moderate: 822, severe: 880). These were univariately associated with serum HP IgG and serum pepsinogen I/II ratio with statistical significance. The multiple logistic analysis calculating standardized coefficients (β) and odds ratio (OR) demonstrated that serum HP IgG (β = 1.499, OR = 4.48), current smoking (β = 0.526, OR = 1.69), age (β = 0.401, OR = 1.49), low serum pepsinogen I/II ratio (β = 0.339, OR = 1.40), and male gender (β = 0.306, OR = 1.36) showed significant positive association with UGI-XR-based atrophic gastritis whereas drinking and body mass index did not. Among the age/sex/smoking/drinking-matched 227 pairs derived from chronically HP-infected and successfully HP-eradicated subjects, UGI-XR-based atrophic gastritis was detected in 99.1% of the former but in only 59.5% of the latter subjects (p<0.0001). Contrastively, UGI-XR-based atrophic gastritis was detected in 13 of 14 HP-positive proton pump inhibitor users (92.9%) and 33 of 34 HP-positive histamine H2-receptor antagonist users (97.1%), which are not significantly different from gastric acid suppressant-free subjects.

    Gastric adenocarcinoma of intestinal type is preceded by inflammation, which produces mucosal atrophy and intestinal metaplasia, progressing eventually to dysplasia and invasive cancer. Recently an international group, the Operative Link on Gastritis Assessment (OLGA) proponed a staging system for gastric biopsies. To recognize the distribution of advanced stages of gastric mucosal atrophy in Mexican patients with dyspepsia according to the OLGA system. We apply the OLGA system for cancer risk (Stages 0 to IV) to 322 gastric biopsies from consecutive patients with dyspepsia. Using the Sydney protocol, we recorded the presence of atrophy, dysplasia and the relationship with ulcer disease. We report the stage of atrophy for each region and the Helicobacter pylori infection status. We documented 72 (22.4%) cases with atrophy, 50 of them (69.4%) were metaplastic-type. Overall, nine biopsies (2.78%) were stage III (all of them with metaplastic-type atrophy) and there was not stage IV cases. We did not find high-grade dysplasia or intramucosal carcinoma. In 8 of subjects with stage III, we observed low-grade dysplasia. We documented gastric ulcer in 5 patients with stage II, 60% of them with associated low-grade dysplasia. Five patients with duodenal ulcer were found in stages 0 and I. We found low prevalence of advanced stages of mucosal gastric atrophy among patients with dyspepsia. However we recognized 9 patients with stage III according to OLGA system worthy of follow-up because the high risk for developing gastric cancer.

    Spices have been used for thousands of years, and recent studies suggest that certain spices confer beneficial effects on gastric disorders. The purpose of this study was to evaluate possible chemopreventive effects of spice-derived compounds on Helicobacter pylori (H. pylori)-induced gastritis. We examined the inhibitory effects of curcumin, capsaicin, and piperine on H. pylori in vitro by determining the colony-forming units and real-time RT-PCR in H. pylori stimulated AGS gastric cancer cells. For in vivo analysis, 6-week-old SPF male Mongolian gerbils were infected with H. pylori, fed diets containing 5000 ppm curcumin, 100 ppm capsaicin, or 100 ppm piperine, and sacrificed after 13 weeks. All three compounds inhibited in vitro proliferation of H. pylori, with curcumin being the most effective. Infiltration of neutrophils and mononuclear cells was suppressed by piperine both in the antrum and corpus of H. pylori-infected gerbils. Capsaicin also decreased neutrophils in the antrum and corpus and mononuclear cell infiltration and heterotopic proliferative glands in the corpus. mRNA expression of Tnf-α and formation of phospho-IκB-α in the antrum were reduced by both capsaicin and piperine. In addition, piperine suppressed expression of Il-1β, Ifn-γ, Il-6, and iNos, while H. pylori UreA and other virulence factors were not significantly attenuated by any compounds. These results suggest that capsaicin and piperine have anti-inflammatory effects on H. pylori-induced gastritis in gerbils independent of direct antibacterial effects and may thus have potential for use in the chemoprevention of H. pylori-associated gastric carcinogenesis. © 2015 John Wiley & Sons Ltd.

    The aim of this study was to compare endoscopic macroscopic classification with fluorine-18 fluorodeoxyglucose (F-18 FDG) uptake in gastric mucosa-associated lymphoid tissue (MALT) lymphoma and to investigate the usefulness of F-18 FDG positron emission tomography (PET) for diagnosing gastric MALT lymphoma. Sixteen patients with gastric MALT lymphoma who underwent F-18 FDG PET and gastrointestinal imaging modalities were included in this study. Sixteen healthy asymptomatic participants undergoing both F-18 FDG PET and endoscopy for cancer screening were in the control group. We investigated the difference of F-18 FDG uptake between the gastric MALT lymphoma and the control group and compared the uptake pattern in gastric MALT lymphoma with our macroscopic classification. The endoscopic findings of 16 gastric MALT lymphoma patients were classified macroscopically as chronic gastritis-like tumors (n = 6), depressed tumors (n = 5), and protruding tumors (n = 5). Abnormal gastric F-18 FDG uptake was observed in 63% of tumors in the gastric MALT lymphoma group and 50% of cases in the control group. The median maximum standardized uptake values for gastric MALT lymphoma patients and control group were 4.0 and 2.6, respectively, the difference of which was statistically significant (P = 0.003). F-18 FDG uptake results were positive for all protruding tumors but only 50% for chronic gastritis-like tumors and 40% for depressed-type tumors. F-18 FDG PET may be a useful method for evaluating protrusion-type gastric MALT lymphoma. When strong focal or diffuse F-18 FDG uptake is detected in the stomach, endoscopic biopsy should be performed, even if the endoscopic finding is chronic gastritis.

    Our previous works have demonstrated that Helicobacter pylori (Hp) infection can alter histone H3 serine 10 phosphorylation status in gastric epithelial cells. However, whether Helicobacter pylori-induced histone H3 serine 10 phosphorylation participates in gastric carcinogenesis is unknown. We investigate the expression of histone H3 serine 10 phosphorylation in various stages of gastric disease and explore its clinical implication. Stomach biopsy samples from 129 patients were collected and stained with histone H3 serine 10 phosphorylation, Ki67, and Helicobacter pylori by immunohistochemistry staining, expressed as labeling index. They were categorized into nonatrophic gastritis, chronic atrophic gastritis, intestinal metaplasia, low-grade intraepithelial neoplasia, high-grade intraepithelial neoplasia, and intestinal-type gastric cancer groups. Helicobacter pylori infection was determined by either 13 C-urea breath test or immunohistochemistry staining. In Helicobacter pylori-negative patients, labeling index of histone H3 serine 10 phosphorylation was gradually increased in nonatrophic gastritis, chronic atrophic gastritis, intestinal metaplasia groups, peaked at low-grade intraepithelial neoplasia, and declined in high-grade intraepithelial neoplasia and gastric cancer groups. In Helicobacter pylori-infected patients, labeling index of histone H3 serine 10 phosphorylation followed the similar pattern as above, with increased expression over the corresponding Helicobacter pylori-negative controls except in nonatrophic gastritis patient whose labeling index was decreased when compared with Helicobacter pylori-negative control. Labeling index of Ki67 in Helicobacter pylori-negative groups was higher in gastric cancer than chronic atrophic gastritis and low-grade intraepithelial neoplasia groups, and higher in intestinal metaplasia group compared with chronic atrophic gastritis group. In Helicobacter pylori-positive groups, Ki67 labeling index was increased

    Atrophic gastritis can be classified according to characteristic mucosal patterns observed by Blue LASER Imaging (BLI) in a medium-range to distant view. To facilitate the endoscopic diagnosis of Helicobacter pylori (HP)-related gastritis, we investigated whether atrophic mucosal patterns correlated with HP infection based on the image interpretations of three endoscopists blinded to clinical features. This study included 441 patients diagnosed as having atrophic gastritis by upper gastrointestinal endoscopy at Nishikawa Gastrointestinal Clinic between April 1, 2015 and March 31, 2016. The presence/absence of HP infection was not taken into consideration. Endoscopy was performed using a Fujifilm EG-L580NW scope. Atrophic mucosal patterns observed by BLI were classified into Spotty, Cracked and Mottled. Image interpretation results were that 89, 122 and 228 patients had the Spotty, Cracked and Mottled patterns, respectively, and 2 patients an undetermined pattern. Further analyses were performed on 439 patients, excluding the 2 with undetermined patterns. The numbers of patients testing negative/positive for HP infection in the Spotty, Cracked and Mottled pattern groups were 12/77, 105/17, and 138/90, respectively. The specificity, positive predictive value and positive likelihood ratio for endoscopic diagnosis with positive HP infection based on the Spotty pattern were 95.3%, 86.5% and 8.9, respectively. In all patients with the Spotty pattern before HP eradication, the Cracked pattern was observed on subsequent post-eradication endoscopy. The Spotty pattern may represent the presence of HP infection, the Cracked pattern, a post-inflammatory change as seen after HP eradication, and the Mottled pattern, intestinal metaplasia.

    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.

    This report is comprised of three parts: the first two parts give a very brief summary of two research projects carried out on groups of chronic, psychiatric out-patients within the framework of the University Psychiatric Policlinic of Lausanne. The third part is an attempt at discerning the fundamental, psychological aspects common to almost all chronic patients as well as the features typical of the relationship between the doctor and his chronic patient. The first piece of research consists of an epidemiological, clinical and catamnestic study of a group of 309 patients. Ten years after the original sample group was selected, 82 patients are still being treated. Various signs help to bring into focus the picture of the so-called chronic patient. They also reveal that the doctor-patient relationship deviated rather rapidly starting right from the first consultation towards a relationship described under the title maintenance service relationship. Furthermore it can be seen that in those groups studied, it was not possible to discern which patients would become seriously chronic at the time when they were first taken in charge. The object of the second study was the medical prescriptions given to a group of 65 chronic patients in treatment from 1965 through 1977. As can be expected in a public service with its frequent change of physicians, the patients were followed by several, not to say numerous, physicians. Regarding the different reasons causing a change of prescription, it is interesting to note that the psychic state of the patient played a much more important role here than the change of the treating physician. Thus the observation of chronic, somatic patients is very useful for the psychological understanding of chronicity. There is, in fact, no concordance between the condition of a person suffering from a chronic, physical illness and a person who is psychologically chronic. A description is given of those factors related to personality structure whose

    A 90-year-old woman was referred and admitted to our hospital because of progressing dementia, decreased appetite, and general fatigue. Blood tests on admission disclosed: white cell count, 2,900 /mm(3); hemoglobin 5.6 g/dl; mean corpuscular volume; 139.7 microm(3). Based on the presence of pancytopenia, macrocytic anemia, and elevated lactate dehydrogenises, we suspected pernicious anemia. We administered vitamin B12, which improved the blood test results and the signs of dementia. Gastrointestinal tract examination showed type A gastritis. Tests for anti-intrinsic factor antibody and anti-gastric parietal cell antibody were positive, which help confirm a diagnosis of pernicious anemia. Pernicious anemia is an autoimmune disease common among those aged 50-60 years. Cases aged over 90 years are rare. However, the numbers of extremely elderly patients are expected to increase with the growth of the elderly population. Fortunately, pernicious anemia is easy to treat. We need to make an appropriate diagnosis of pernicious anemia in the oldest elderly patients.

    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.

    Even though Ga-67 imaging has been used widely in the diagnosis of malignant as well as inflammatory lesions, its uptake in the stomach has been reported in the literature mainly in gastric lymphoma and carcinoma. As shown in this case, intense gastric uptake of the radionuclide may be seen in common gastritis without malignancy. Perhaps the benign gastric uptake of Ga-67 deserves more emphasis.

    Helicobacter pylori (H. pylori) is a human gastric pathogen, causing various gastric diseases ranging from gastritis to gastric adenocarcinoma. It has been reported that combining N-acetylcysteine (NAC) with conventional antibiotic therapy increases the success rate of H. pylori eradication. We evaluated the effect of NAC itself on the growth and colonization of H. pylori, and development of gastritis, using in vitro liquid culture system and in vivo animal models. H. pylori growth was evaluated in broth culture containing NAC. The H. pylori load and histopathological scores of stomachs were measured in Mongolian gerbils infected with H. pylori strain 7.13, and fed with NAC-containing diet. In liquid culture, NAC inhibited H. pylori growth in a concentration-dependent manner. In the animal model, 3-day administration of NAC after 1 week from infection reduced the H. pylori load; 6-week administration of NAC after 1 week from infection prevented the development of gastritis and reduced H. pylori colonization. However, no reduction in the bacterial load or degree of gastritis was observed with a 6-week administration of NAC following 6-week infection period. Our results indicate that NAC may exert a beneficial effect on reduction of bacterial colonization, and prevents the development of severe inflammation, in people with initial asymptomatic or mild H. pylori infection.

    To determine the prevalence and severity of psychological comorbidity in patients with chronic tinnitus in comparison with other chronic illnesses, namely chronic pain, chronic asthma and atopic dermatitis. Psychological diagnoses were done according to ICD-10 Chapter V(F). Subjective impairment was evaluated using 5 psychometric questionnaires: tinnitus questionnaire, Berlin mood questionnaire, sense of coherence (SOC-L9) and perceived stress questionnaire. Sleep disturbance was measured by the subdomain 'exhaustion' of the Giessen physical complaints inventory. Somatoform or affective disorders were most frequent in all disease groups. Patients with chronic tinnitus had a stronger SOC and better subjective mood, stronger commitment, and less anger and anxious depression than the patients with chronic pain, chronic asthma or atopic dermatitis. However, in patients with higher tinnitus annoyance, psychological comorbidity was similar to that found in patients with other chronic diseases. Besides collecting medical and social history, special psychometric instruments should be used for the diagnosis of tinnitus patients. Based on relative high frequency of psychological comorbidity, we recommend interdisciplinary cooperation between otorhinolaryngologists and other specialists (psychosomatic medicine, psychology or psychiatry) during the treatment of tinnitus patients, especially when high degree of tinnitus annoyance is involved.

    International Agency for Research on Cancer recognized as sufficient the evidence of Helicobacter pylori (HP) infection carcinogenicity and placed it into the 1 st group of carcinogens. Micronucleus level in gastric epithelial cells of antral stomach region of patients with chronic non-atrophy gastritis (n = 62) was studied. 40 patients of 62 had HP-associated gastritis. The HP-bacterium exists in a spiral and coccoid form. Both morphological forms were examined using immunocytochemistry. Significantly increased micronucleus number was observed in the cells of HP-infected patients compared with non-infected person (P < 0.05). The frequency of stomach epithelium cells with micronuclei was enhanced considerably in the patients infected with the coccoid HP form. Therefore the patients with HP-associated chronic gastritis caused by the coccoid form with high degree of colonization must be considered as a group of enhanced risk of gastric carcinogenesis.

    Cathelicidin, an antimicrobial peptide of the innate immune system, has been shown to modulate microbial growth, wound healing and inflammation. However, whether cathelicidin controls Helicobacter pylori infection in vivo remains unexplored. This study sought to elucidate the role of endogenous and exogenous mouse cathelicidin (CRAMP) in the protection against H. pylori infection and the associated gastritis in mice. Results showed that genetic ablation of CRAMP in mice significantly increased the susceptibility of H. pylori colonization and the associated gastritis as compared with the wild-type control. Furthermore, replenishment with exogenous CRAMP, delivered via a bioengineered CRAMP-secreting strain of Lactococcus lactis, reduced H. pylori density in the stomach as well as the associated inflammatory cell infiltration and cytokine production. Collectively, these findings indicate that cathelicidin protects against H. pylori infection and its associated gastritis in vivo. Our study also demonstrates the feasibility of using the transformed food-grade bacteria to deliver cathelicidin, which may have potential clinical applications in the treatment of H. pylori infection in humans.

    Eosinophilic gastritis (EG) and eosinophilic gastroenteritis (EGE) are chronic immune-mediated conditions of the digestive tract, which affect the stomach only, or the stomach and small intestines, respectively. Though these disorders are uncommon, they are being increasingly recognized and diagnosed. While health-related quality of life (HRQOL) has been evaluated in other eosinophilic gastrointestinal diseases, this study is the first to describe HRQOL impacts unique to EG/EGE. This study aims to qualitatively describe experiences of adults diagnosed with EG and EGE. We aim to identify impacts on HRQOL in this population in order to inform clinical care and assessment. Seven patients diagnosed with EG or EGE participated in semi-structured interviews assessing common domains of HRQOL. Four distinct themes emerged from qualitative analyses, which represent impacts to HRQOL: the psychological impact of the diagnosis, impact on social relationships, financial impact, and impact on the body. These generally improved over time and with effective treatment. This study demonstrated that patients with EG/EGE experience impacts to HRQOL, some of which differ from HRQOL of other eosinophilic gastrointestinal diseases. These results support the development of a disease-specific measure, or adaptation of an existing measure, to assess HRQOL in EG/EGE.

    Objective Investigate whether high-quality chronic care delivery improved the experiences of patients. Design This study had a longitudinal design. Setting and Participants We surveyed professionals and patients in 17 disease management programs targeting patients with cardiovascular diseases, chronic obstructive pulmonary disease, heart failure, stroke, comorbidity and eating disorders. Main Outcome Measures Patients completed questionnaires including the Patient Assessment of Chronic Illness Care (PACIC) [T1 (2010), 2637/4576 (58%); T2 (2011), 2314/4330 (53%)]. Professionals' Assessment of Chronic Illness Care (ACIC) scores [T1, 150/274 (55%); T2, 225/325 (68%)] were used as a context variable for care delivery. We used two-tailed, paired t-tests to investigate improvements in chronic illness care quality and patients' experiences with chronic care delivery. We employed multilevel analyses to investigate the predictive role of chronic care delivery quality in improving patients' experiences with care delivery. Results Overall, care quality and patients' experiences with chronic illness care delivery significantly improved. PACIC scores improved significantly from 2.89 at T1 to 2.96 at T2 and ACIC-S scores improved significantly from 6.83 at T1 to 7.18 at T2. After adjusting for patients' experiences with care delivery at T1, age, educational level, marital status, gender and mental and physical quality of life, analyses showed that the quality of chronic care delivery at T1 (P < 0.001) and changes in care delivery quality (P < 0.001) predicted patients' experiences with chronic care delivery at T2. Conclusion This research showed that care quality and changes therein predict more positive experiences of patients with various chronic conditions over time. PMID:24123243

    We have reported the short-term results of pylorus reconstruction gastrectomy (PRG) that prevents duodenogastric reflux (DGR) and remnant gastritis after distal gastrectomy. We herein report the long-term results of the PRG. PRG was performed in 37 patients (age 31 to 86 [mean 67.8 ± 12.3] years, male:female = 22:15) with gastric cancer from June 2006 through December 2013. We examined the long-term outcome in 28 patients (age 41 to 86 [mean 67.0 ± 10.7] years, male:female = 18:10) that passed over 3 years after surgery (LTR 44.1 ± 11.7 months), and compared with their short-term result after the operation (STR 13.1 ± 6.9 months). The adverse events of gastric surgery evaluated in this study consisted of the degree of remnant gastritis, the presence of dumping syndrome, and degree of weight loss (%). There was no difference in the degree of DGR and remnant gastritis by gastroscopic finding between LTR and STR after PRG (P = 0.21). Statistically, there was no difference in the bile acid concentration of remnant gastric juice between LTR and STR (108.4 ± 254.1 vs. 94.0 ± 208.6 μmol/L, P = 0.33), and weight loss of LTR was the same as that of STR (5.67 ± 7.08 vs. 4.59 ± 5.63%, P = 0.34). There were few morphological changes in the reconstructed pylorus by the long-term course, but 2 patients showed mild atrophy. The form of reconstructed pylorus and the effect that reduces side effects of Billroth I seem to last for a long time.

    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

    BACKGROUND Many studies have reported an association between periodontal infections and some systemic diseases such as respiratory and cardiovascular diseases. Some studies found a direct association between chronic gastritis caused by Helicobacter pylori (HP) infection and poor periodontal health. METHODS In a cross-sectional study from November 2014 to December 2015 in Kerman, the largest province in southeast Iran, patients with dyspepsia who were candidate for diagnostic upper gastrointestinal (GI) endoscopy were included in our study. Decayed, Missing, and Filled Teeth (DMFT) index and Loe plaque index that are two popular indexes in dental epidemiology were used to assess the oral health by a dentist before the upper GI endoscopy. According to the Loe plaque index, score: 0= no plaque, score: 1= a film of plaque attaching to the free gingival border and near area of the tooth, score: 2= moderate reposition of deposits within the gingival pocket, score :3= plenty of soft matter within the gingival pocket±on the tooth and gingival border. Scores ≤1, 2 and 3 equal to good, moderate, and poor oral hygiene, respectively. During upper GI endoscopy a total of six biopsy samples were taken from fundus, body, and antrum.

    Objective Gastric carcinoma development is triggered by Helicobacter pylori. Chronic H. pylori infection leads to reduced acid secretion, which may allow the growth of a different gastric bacterial community. This change in the microbiome may increase aggression to the gastric mucosa and contribute to malignancy. Our aim was to evaluate the composition of the gastric microbiota in chronic gastritis and in gastric carcinoma. Design The gastric microbiota was retrospectively investigated in 54 patients with gastric carcinoma and 81 patients with chronic gastritis by 16S rRNA gene profiling, using next-generation sequencing. Differences in microbial composition of the two patient groups were assessed using linear discriminant analysis effect size. Associations between the most relevant taxa and clinical diagnosis were validated by real-time quantitative PCR. Predictive functional profiling of microbial communities was obtained with PICRUSt. Results The gastric carcinoma microbiota was characterised by reduced microbial diversity, by decreased abundance of Helicobacter and by the enrichment of other bacterial genera, mostly represented by intestinal commensals. The combination of these taxa into a microbial dysbiosis index revealed that dysbiosis has excellent capacity to discriminate between gastritis and gastric carcinoma. Analysis of the functional features of the microbiota was compatible with the presence of a nitrosating microbial community in carcinoma. The major observations were confirmed in validation cohorts from different geographic origins. Conclusions Detailed analysis of the gastric microbiota revealed for the first time that patients with gastric carcinoma exhibit a dysbiotic microbial community with genotoxic potential, which is distinct from that of patients with chronic gastritis.

    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. © 2011 Wiley Periodicals, Inc.

    Managing multiple chronic health conditions is a significant challenge. The purpose of this study was to examine the experience and management of chronic pain among adult patients with other complex chronic conditions, specifically diabetes and heart failure (HF). We surveyed 624 US Department of Veterans Affairs primary care patients in 3 study groups: 184 with HF, 221 with diabetes, and 219 general primary care users. We compared health status and function between those with and without chronic pain within the 3 study groups. Among those with chronic pain, we compared pain location, severity, and treatment across groups. More than 60% in each group reported chronic pain, with the majority reporting pain in the back, hip, or knee. In all groups, patients with chronic pain were more likely to report fair or poor health than those without pain (P<0.05). In the HF and diabetes groups, a higher percentage of patients with pain were not working because of health reasons. Of those with pain, more than 70% in each group took medications for pain; more than one-half managed pain with rest or sedentary activities; and less than 50% used exercise for managing their pain. Chronic pain is a prevalent problem that is associated with poor functioning among multimorbid patients. Better management of chronic pain among complex patients could lead to significant improvements in health status, functioning, and quality of life and possibly also improve the management of their other major chronic health conditions.

    Studies were performed in patients with and without renal failure to investigate the role of bacterial ammonia production in the pathogenesis of the mucosal abnormalities caused by Helicobacter pylori. The high rate of H pylori ammonia production in uraemic patients should accentuate any ammonia induced effects. The median (range) gastric juice ammonium concentration in the H pylori positive patients with renal failure was 19 mmol/l (II-43) compared with 5 mmol/l (1-11) in the H pylori positive patients without renal failure (p < 0.005). In the H pylori negative patients the values were 3 mmol/l (0.5-11) and 0.7 mmol/l (0.1-1.4) respectively in the patients with and without renal failure (p < 0.01). Despite the much higher ammonia production in the H pylori positive uraemic patients, the nature and severity of their gastritis was the same as that in the H pylori positive non-uraemic patients. The median (range) fasting serum gastrin concentration was raised in the uraemic patients compared with the non-uraemic patients but was similar in the uraemic patients with (95 pmol/l (52-333)) or without (114 pmol/l (47-533)) H pylori infection. The median (range) serum pepsinogen I concentration was also high in the uraemic compared with the non-uraemic patients and was significantly higher in uraemic patients with H pylori (352 ng/ml, range 280-653) than in those without H pylori infection (165 ng/ml, range 86-337) (p < 0.01). These findings indicate that the gastritis and hypergastrinaemia associated with H pylori infection are not the result of mucosal damage induced by the organism's ammonia production. PMID:1487161

    To compare the efficacy of intravenous ondansetron or dexamethasone compared with intravenous fluid therapy alone in children presenting to the emergency department with refractory vomiting from viral gastritis who had failed attempts at oral hydration. This double-blind, randomized, controlled trial was performed in a tertiary care pediatric emergency department. Children aged 6 months to 12 years presenting with more than three episodes of vomiting in the past 24 hours, mild/moderate dehydration, and failed oral hydration were included. Patients with other medical causes were excluded. Subjects were randomized to dexamethasone 1 mg/kg (15 mg maximum), ondansetron 0.15 mg/kg, or placebo (normal saline [NS], 10 mL). All subjects also received intravenous NS at 10-20 mL/kg/hr. Oral fluid tolerance was evaluated at two and four hours. Those not tolerating oral fluids at four hours were admitted. Discharged patients were evaluated at 24 and 72 hours for vomiting and repeat health care visits. The primary study outcome was hospitalization rates between the groups. Data were analyzed using chi-square test, Kruskal-Wallis test, Mantel-Haenszel test, and analysis of variance, with p < 0.05 considered significant. A total of 166 subjects were enrolled; data for analysis were available for 44 NS-treated patients, 46 ondansetron-treated patients, and 47 dexamethasone-treated patients. Hospital admission occurred in nine patients (20.5%) receiving placebo (NS alone), two patients (4.4%) receiving ondansetron, and seven patients (14.9%) receiving dexamethasone, with ondansetron significantly different from placebo (p = 0.02). Similarly, at two hours, more ondansetron-treated patients (39 [86.6%]) tolerated oral hydration than NS-treated patients (29 [67.4%]; relative risk, 1.28; 95% confidence interval = 1.02 to 1.68). There were no differences in number of mean episodes of vomiting or repeat visits to health care at 24 and 72 hours in the ondansetron, dexamethasone, or NS

    To propose pharmacotherapy of disbacteriosis of gastroduodenal mucous microflora in gastroduodenal inflammation, erosion and ulcer. The study enrolled 30 healthy volunteers, 130 ulcer patients and 36 patients with chronic gastritis (27% of the latter had chronic duodenitis). In addition to general clinical examination, fibrogastroduodenoscopy, we made histological and microbiological examinations of biopsy specimens of the mucosa from different parts of the stomach and duodenum, determined sensitivity of the microflora to antibacterial drugs. We found that recurrent ulcer, chronic gastritis and duodenitis are accompanied with overgrowth of pathogenic microflora in gastric and duodenal mucosa. We developed an effective method of the treatment of gastroduodenal mucosa microflora disbacteriosis in gastroduodenal inflammation, erosion and ulcer including antibacterial, antifungal drugs and probiotics.

    Chronic pain is a public health concern affecting 20-30% of the population of Western countries. Although there have been many scientific advances in the understanding of the neurophysiology of pain, precisely assessing and diagnosing a patient's chronic pain problem is not straightforward or well-defined. How chronic pain is conceptualized influences how pain is evaluated and the factors considered when making a chronic pain diagnosis. There is no one-to-one relationship between the amount or type of organic pathology and pain intensity, but instead, the chronic pain experience is shaped by a myriad of biomedical, psychosocial (e.g. patients' beliefs, expectations, and mood), and behavioural factors (e.g. context, responses by significant others). Assessing each of these three domains through a comprehensive evaluation of the person with chronic pain is essential for treatment decisions and to facilitate optimal outcomes. This evaluation should include a thorough patient history and medical evaluation and a brief screening interview where the patient's behaviour can be observed. Further assessment to address questions identified during the initial evaluation will guide decisions as to what additional assessments, if any, may be appropriate. Standardized self-reported instruments to evaluate the patient's pain intensity, functional abilities, beliefs and expectations, and emotional distress are available, and can be administered by the physician, or a referral for in depth evaluation can be made to assist in treatment planning.

    To identify which technique is better for avoiding biliary reflux and gastritis between uncut Roux-en-Y and Billroth II reconstruction. A total of 158 patients who underwent laparoscopy-assisted distal gastrectomy for gastric cancer at the First Hospital of Jilin University (Changchun, China) between February 2015 and February 2016 were randomized into two groups: uncut Roux-en-Y (group U) and Billroth II group (group B). Postoperative complications and relevant clinical data were compared between the two groups. According to the randomization table, each group included 79 patients. There was no significant difference in postoperative complications between groups U and B (7.6% vs 10.1%, P = 0.576). During the postoperative period, group U stomach pH values were lower than 7 and group B pH values were higher than 7. After 1 year of follow-up, group B presented a higher incidence of biliary reflux and alkaline gastritis. However, histopathology did not show a significant difference in gastritis diagnosis ( P = 0.278), and the amount of residual food and gain of weight between the groups were also not significantly different. At 3 mo there was no evidence of partial recanalization of uncut staple line, but at 1 year the incidence was 13%. Compared with Billroth II reconstruction, uncut Roux-en-Y reconstruction is secure and feasible, and can effectively reduce the incidence of alkaline reflux, residual gastritis, and heartburn. Despite the incidence of recanalization, uncut Roux-en-Y should be widely applied.

    Alterations in the immune response of patients with autoimmune diseases may predispose to malignancies, and a link between chronic autoimmune gastritis and gastric cancer has been reported in many studies. Intestinal metaplasia with dysplasia of the gastric corpus-fundus mucosa and hyperplasia of chromaffin cells, which are typical features of late-stage autoimmune gastritis, are considered precursor lesions. Autoimmune gastritis has been associated with the development of two types of gastric neoplasms: intestinal type and type I gastric carcinoid. Here, we review the association of autoimmune gastritis with gastric cancer and other autoimmune features present in gastric neoplasms. PMID:29373557

    AIM: To investigate the characteristics of gastric cancer and gastric mucosa in a Mongolian population by comparison with a Japanese population. METHODS: A total of 484 Mongolian patients with gastric cancer were enrolled to study gastric cancer characteristics in Mongolians. In addition, a total of 208 Mongolian and 3205 Japanese consecutive outpatients who underwent endoscopy, had abdominal complaints, no history of gastric operation or Helicobacter pylori eradication treatment, and no use of gastric secretion inhibitors such as histamine H2-receptor antagonists or proton pump inhibitors were enrolled. This study was conducted with the approval of the ethics committees of all hospitals. The triple-site biopsy method was used for the histologic diagnosis of gastritis and H. pylori infection in all Mongolian and Japanese cases. The infection rate of H. pylori and the status of gastric mucosa in H. pylori-infected patients were compared between Mongolian and Japanese subjects. Age (± 5 years), sex, and endoscopic diagnosis were matched between the two countries. RESULTS: Approximately 70% of Mongolian patients with gastric cancer were 50-79 years of age, and approximately half of the cancers were located in the upper part of the stomach. Histologically, 65.7% of early cancers exhibited differentiated adenocarcinoma, whereas 73.9% of advanced cancers displayed undifferentiated adenocarcinoma. The infection rate of H. pylori was higher in Mongolian than Japanese patients (75.9% vs 48.3%, P < 0.0001). When stratified by age, the prevalence was highest among young patients, and tended to decrease in patients aged 50 years or older. The anti-East-Asian CagA-specific antibody was negative in 99.4% of H. pylori-positive Mongolian patients. Chronic inflammation, neutrophil activity, glandular atrophy, and intestinal metaplasia scores were significantly lower in Mongolian compared to Japanese H. pylori-positive patients (P < 0.0001), with the exception of the intestinal

    To investigate the presence of IgG4+ plasma cells in gastric mucosal biopsy samples from patients with atrophic gastritis (AG) and a history of pernicious anaemia (PA) (AG+PA+). Gastric mucosal biopsy specimens from 46 patients with AG+PA+ were investigated. As controls, we evaluated specimens from patients with AG but no history of PA (AG+ PA-) (n=25), normal histology (n=25), mild chronic inactive gastritis (MCIG) (n=25) or Helicobacter pylori gastritis (HP) (n=25). IgG4+ plasma cells were detected by two immunohistochemical methods: (1) using a monoclonal antibody, the average of the three most cellular high-power fields was counted in areas with the highest density of IgG4+ plasma cells; (2) using a dual-chromagen stain for both IgG4 and CD138 (plasma cell marker), the number of IgG4+ cells per 200 CD138+ plasma cells was counted. The latter was used to ensure that the number of IgG4+ cells was not simply related to the degree of inflammation (density of plasma cells). Identical results were obtained with the two staining methods. Increased numbers of IgG4+ plasma cells were present in 37% of patients with AG+PA+, but in none with AG+PA-, MCIG, HP or normal gastric biopsy results (100% specific, p=0.0001). IgG4+ plasma cells may play a role in the pathogenesis of PA and may be a useful marker for its diagnosis.

    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 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.

    To describe a case of necroulcerative gastritis in a cat secondary to administration of 3% hydrogen peroxide as an emetic agent. A 10-year-old neutered male domestic shorthair was evaluated for hematemesis less than 24 hours following ingestion of a piece of foam. The pet owner had administered 2 doses of 0.5-1.0 tablespoons (7.5-15 mL) of 3% hydrogen peroxide in an attempt to induce emesis at home; emesis was achieved and produced the foam foreign body. Due to the presence of protracted vomiting and hematemesis, the patient was then presented to an emergency facility for further diagnostics and treatment. Initial blood work was normal on presentation, and advanced imaging of the abdomen was performed. An exploratory laparotomy revealed no foreign material in the gastrointestinal tract; however, severe ulceration of approximately 60% of the gastric mucosa was observed around the cardia and extended from the fundus down through the body of the stomach to the lesser curvature. Due to the severity of ulceration and presumed poor prognosis, the patient was euthanized intraoperatively. Histopathology of the stomach wall was consistent with severe confluent necroulcerative and hemorrhagic pleocellular gastritis, presumed to be secondary to administration of 3% hydrogen peroxide, which was used as the primary emetic agent in this case. The oral administration of 3% hydrogen peroxide solution in cats can result in necroulcerative gastritis as a possible sequel. While hydrogen peroxide is considered a safe emetic agent in dogs, its use in cats is not recommended. As a result, the use of emetic agents in cats should be limited to veterinary administration, using alternative, safer emetic agents such as alpha-adrenergic agonists. © Veterinary Emergency and Critical Care Society 2017.

    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 thatmore » control these reactions.« less

    Laboratory mice have become one of the best animal species for mechanistic studies in gastrointestinal research. Their abundant genetic information, the way of causing carcinogenesis easily by transgenic and gene knockout techniques, limited effort in time and costs, and their practicability provide advantages over other animal models. Meanwhile, several murine practical models have been established for the investigation of the initiation, expansion, and progression of gastritis and gastric carcinoma, for assessing the effects of bacterial, genetic and environmental factors, and for evaluating therapeutic and preventive strategies in gastric diseases. This article gives a review of murine models of gastritis and gastric cancer, placing emphasis on the models associated with Helicobacter pylori infection and techniques used in our laboratory. We discuss matters of murine gastric anatomy, as well as techniques of infection, tissue preparation, and histology. Copyright © 2011 Elsevier GmbH. All rights reserved.

    This study compared the efficacy of DA-9601 (Dong-A ST Co., Seoul, Korea) and its new formulation, DA-5204 (Dong-A ST Co.), for treating erosive gastritis. This phase III, randomized, multicenter, double-blind, non-inferiority trial randomly assigned 434 patients with endoscopically proven gastric mucosal erosions into two groups: DA-9601 3 times daily or DA-5,204 twice daily for 2 weeks. The final analysis included 421 patients (DA-5204, 209; DA-9601, 212). The primary endpoint (rate of effective gastric erosion healing) and secondary endpoints (cure rate of endoscopic erosion and gastrointestinal [GI] symptom relief) were assessed using endoscopy after the treatment. Drug-related adverse events (AEs), including GI symptoms, were also compared. At week 2, gastric healing rates with DA-5204 and DA-9601 were 42.1% (88/209) and 42.5% (90/212), respectively. The difference between the groups was -0.4% (95% confidence interval, -9.8% to 9.1%), which was above the non-inferiority margin of -14%. The cure rate of gastric erosion in both groups was 37.3%. The improvement rates of GI symptoms with DA-5204 and DA-9601 were 40.4% and 40.8%, respectively. There were no statistically significant differences between the two groups in both secondary endpoints. AEs were reported in 18 (8.4%) patients in the DA-5204 group and 19 (8.8%) in the DA-9601 group. Rates of AE were not different between the two groups. No serious AE or adverse drug reaction (ADR) occurred. These results demonstrate the non-inferiority of DA-5204 compared to DA-9601.

    Gastric epithelial hyper-proliferation was reported in patients with Helicobacter pylori (H. pylori)-infected gastric mucosa with intestinal metaplasia (IM) changes. In patients with gastric ulcer (GU) and IM, the GU may have a different healing rate in comparison to patients without IM. This study aimed to compare the difference in GU healing between H. pylori-infected patients with IM and those without IM. We retrospectively analyzed patients at the Keelung Chung Gung Memorial Hospital during the period from March 2005 to January 2011. The inclusion criteria were: 1) endoscopic findings of GU and biopsy histological examination plus rapid urease test indicating H. pylori infection; 2) gastric IM adjacent to a GU but with no atrophic gastritis changes; 3) patients receiving H. pylori eradication triple therapy and 8 weeks of maintenance therapy with a proton pump inhibitor; and 4) patients receiving follow-up endoscopy within the 3 rd and the 4 th months after treatment. In total, 327 patients with GU and H. pylori infection (136 with IM and 191 without IM) were included. Patients with IM had a higher GU healing rate than those without IM (91.9% vs. 84.3%, P = 0.040). Multivariate logistical regression analysis revealed that failure of H. pylori eradication (Odds = 4.013, 95% CI: 1.840-8.951, P < 0.001) and gastric IM (Odds = 0.369, 95% CI: 0.168-0.812, P = 0.013) were the predictors of non-healing GU following treatment. Patient with gastric IM change may have a higher GU healing rate than those without gastric IM. However, successful H. pylori eradication is a more important factor for GU healing than gastric IM.

    Patients with chronic heart failure (HF) are limited in their quality of life, have a poor prognosis and face frequent hospitalisations. Patient self-management was shown to improve quality of life, reduce rehospitalisations and costs in patients with chronic HF. Comprehensive disease management programmes are critical to foster patient self-management. The chronic care model developed by the WHO serves as the basis of such programmes. In order to develop self-management skills a needs orientated training concept is mandatory, as patients need both knowledge of the illness and the ability to use the information to make appropriate decisions according to their individual situation. Switzerland has no established system for the care of patients with chronic diseases in particular those with HF. For this reason a group of Swiss experts for HF designed a model for disease management for HF patients in Switzerland. Since 2009 the Swiss Heart Foundation offers an education programme based on this model. The aim of this programme is to offer education and support for practitioners, patients and families. An initial pilot evaluation of the program showed mixed acceptance by practitioners, whereas patient assessed the program as supportive and in line with their requirements.

    The Kyoto global consensus report on Helicobacter pylori (H. pylori) gastritis has had a great effect on the field of H. pylori studies worldwide. For the first time H. pylori gastritis was defined entirely as an infectious disease and H. pylori-associated dyspepsia as a new category of organic dyspepsia apart from functional dyspepsia, together with a proposed diagnostic algorithm. Accordingly, the report states that the eradication of H. pylori should be regarded as the first-line treatment for dyspepsia. Moreover, H. pylori eradication before the development of pre-neoplastic changes is recommended to reduce the risk of more serious complications of H. pylori gastritis. Despite the recommendations of this new global consensus, the task of transforming them into feasible and practical recommendations for individual countries will require them to become region-specific, which requires further discussion. © 2016 Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine and John Wiley & Sons Australia, Ltd.

    Assessment of physical and psychosocial dysfunction is recognized as essential in chronic pain patient evaluation. One instrument, the Sickness Impact Profile (SIP), has demonstrated good reliability and validity as a measure of dysfunction among chronic pain patients. An alternate measure, the Chronic Illness Problem Inventory (CIPI), is shorter and more easily scored than the SIP, but as yet has not been applied widely to chronic pain problems. In the present study, 95 chronic low back pain patients completed the SIP, the CIPI, activity diaries, the McGill Pain Questionnaire (MPQ), and the Center for Epidemiologic Studies-Depression scale (CES-D), before participating in a chronic pain treatment study. Overt pain behaviors were also coded from videotapes of a standardized assessment protocol. Seventy-five subjects completed the measures post-treatment. The results indicate that although the SIP and the CIPI are significantly correlated and appear to be measuring similar constructs, there is also substantial unshared variance between them, suggesting that they may tap somewhat different aspects of dysfunction in chronic pain. The CIPI shows promise as a useful alternative measure of dysfunction in chronic low back pain patients, but requires further validation for this purpose.

    Helicobacter pylori secretory peptidyl prolyl isomerase, HP0175, is progressively identified as a pro-inflammatory and pro-carcinogenic protein, which serves to link H. pylori infection to its more severe clinical outcomes. Here, we have analyzed host HP0175-specific antibody responses in relation to the severity of gastritis. The HP0175 gene fragment was PCR-amplified, cloned, expressed and purified by Ni-NTA affinity chromatography. Serum antigen-specific antibody responses of non-ulcer dyspeptic patients (N = 176) against recombinant HP0175 were detected by western blotting. The infection status of these subjects was determined by rapid urease test, culture, histology, and serology. The grade of inflammation and stage of atrophy were scored blindly according to the OLGA staging system. The recombinant HP0175 (rHP0175) was expressed as a ~35 kDa protein and its identity was confirmed by western blotting using anti-6X His tag antibody and pooled H. pylori-positive sera. Serum IgG antibodies against rHP0175 segregated our patients into two similar-sized groups of sero-positives (90/176, 51.1 %) and sero-negatives (86/176, 48.9 %). The former presented with higher grades of gastric inflammation (OR = 4.4, 95 % CI = 1.9-9.9, P = 0.001) and stages of gastric atrophy (OR = 18.3, 95 %CI = 1.4-246.6, P = 0.028). Our findings lend further support to the pro-inflammatory nature of H. pylori peptidyl prolyl isomerase (HP0175) and recommends this antigen as a non-invasive serum biomarker of the severity of H. pylori-associated gastritis.

    Metabolic disturbances were corrected using the oral specialized formula Nutrien-phthisio (ZAO "Company Nutritec", Russia) in 53 patients with pulmonary tuberculosis and concomitant diseases. In the whole group, tuberculosis was first detected in 21 patients; 32 had a chronic process. Chemotherapy was discontinued in all the patients due to the intolerance phenomena caused by comorbidity (erosive gastritis, gastroduodenal peptic ulcer, hepatitis B and C, chronic pyelonephritis) in 24 patients, by adverse reactions in 19, and by a combination of both factors in 10. The criteria for objectively monitoring the efficiency of nutritional support (in combination with specific treatment) were body mass index, general blood analysis, by taking into account the percentage and absolute count of lymphocytes and the protein metabolism from the serum levels of total protein, albumin, and transferrin. The study determined clinical and laboratory indications for the use of Nutrien-phthisio and the favorable impact of nutritional support on the course of a tuberculous process and concomitant diseases.

    To study treatment motivation in patients with chronic heart failure (CHF) and in those with CHF concurrent with chronic kidney disease (CKD). A total of 203 patients (130 men and 73 women; mean age, 61.8±9.6 years) with CHF diagnosed and assessed in accordance with the National Guidelines of the All-Russian Research Society of Cardiology and the Heart Failure Society for the diagnosis and treatment of CHF (third edition, 2009) were examined. CKD was diagnosed according to the 2012 National Guidelines of the Research Nephrology Society of Russia. A group of patients with chronic cardiorenal syndrome (CRS) included those with CHF and CKD with a glomerular filtration rate (GFR) of <60 ml/min/1.73 m2. The clinical course of CHF, personality profile, and motivation for non-drug and drug treatments were assessed in patients with chronic CRS. CFR was 67.7±17.2 ml/min/1.73 m2; chronic CRS was observed in 89 (44%) patients. Psychological functioning assessment showed that the patients with chronic CRS as compared with those with CHF without CKD had high anxiety and maladaptive disease attitudes. CHF treatment motivation (compliance with lifestyle modification and medication) was proved inadequate and detected only in 31 (15.3%) patients with CHF regardless of the presence of CKD. The specific features of psychological functioning, which affected treatment motivation, were seen in patients with chronic CRS: those who were lowly motivated had a euphoric attitude towards their disease (p=0.03); those who were satisfactorily motivated showed an emotive accentuation of character (p=0.002). The presence of CKD aggravates the clinical course of CHF and negatively affects the psychological functioning of patients with CHF. The patients with chronic CRS are characterized by a low level of motivation for both drug and non-drug treatments, which should be taken into account when managing this cohort of patients.

    Follicular gastritis (FG) is characterized by lymphoid follicle hyperplasia in the gastric mucosa. The aim of this prospective study was to determine the prevalence of FG in adults, their relation to Helicobacter pylori infection, and their histological and endoscopic features. Of 445 patients (379 men, 66 women), 36.4 years old (range: 18-86), FG was detected in 63 patients (14.2%). This was highly significantly associated with H. pylori infection: 49/138 infected patients (35.5%) versus 14/307 non infected patients (4.6%) (P < 0.001). None of the histological features of the antral mucosa were correlated with FG. The prevalence of FG in patients less than 20 years old (in 45.4%) and between 20 and 40 years (in 41.3%) was higher than in patients aged from 40 to 60 years (in 33%) and older than 60 years (in 23%) (no significant difference). No one endoscopic feature of the gastric mucosa was predictive of the presence of FG. We conclude that FG is highly correlated with H. pylori infection and represents a local immune response to bacterial antigens. Their occurrence is probably multifactorial and related to age, duration of infection, bacterial strains, host immune status.

    It is still disputed whether gastric atrophy or intestinal metaplasia improves after the cure of Helicobacter pylori infection. To clarify the histological changes after the cure of H. pylori infection through a literature survey. Fifty-one selected reports from 1066 relevant articles were reviewed. The extracted data were pooled according to histological parameters of gastritis based on the (updated) Sydney system. Activity improved more rapidly than inflammation. Eleven of 25 reports described significant improvement of atrophy. Atrophy was not improved in one of four studies with a large sample size (> 100 samples) and in two of five studies with a long follow-up period (> 12 months), suggesting that disagreement between the studies was not totally due to sample size or follow-up period. Methodological flaws, such as patient selection, and statistical analysis based on the assumption that atrophy improves continuously and generally in all patients might be responsible for the inconsistent results. Four of 28 studies described significant improvement of intestinal metaplasia [corrected]. Activity and inflammation were improved after the cure of H. pylori infection. Atrophy did not improve generally among all patients, but improved in certain patients. Improvement of intestinal metaplasia was difficult to analyse due to methodological problems including statistical power.

    Corpus-dominant lymphocytic gastritis (LyG) is characterized by CD8 + T-cell infiltration of the stomach epithelium by a so far uncharacterized mechanism. Although Helicobacter pylori is typically undetectable in LyG, patients respond to H. pylori antibiotic eradication therapy, suggesting a non-H. pylori microbial trigger for the disease. Comparative microbiota analysis of specimens from LyG, H. pylori gastritis and healthy controls precluded involvement of H. pylori in LyG but identified Propionibacterium acnes as a possible disease trigger. In addition, the natural killer group 2 member D (NKG2D) system and the proinflammatory cytokine interleukin (IL)-15 are significantly upregulated in the gastric mucosa of LyG patients, and gastric epithelial cells respond to microbe-derived stimuli, including live P. acnes and the microbial products short-chain fatty acids, with induction of NKG2D ligands. In contrast, H. pylori infection does not activate or even repress NKG2D ligands. Together, our findings identify P. acnes as a possible causative agent for LyG, which is dependent on the NKG2D system and IL-15 activation. © 2016 The Authors.

    Helicobacter pylori (H. pylori) chronically colonizes gastric/duodenal mucosa and induces gastroduodenal disease such as gastritis and peptic ulcer and induces vigorous innate and specific immune responses; however, the infection is not removed, a state of chronic active gastritis persists for life if untreated. The objective of this study was to determine the number of regulatory T cells (Tregs) in gastric mucosa of patients with gastritis and peptic ulcer and determined the relationship between main virulence factor of H. pylori and Tregs. A total of 89 patients with gastritis, 63 patients with peptic ulcer and 40 healthy, H. pylori-negative subjects were enrolled in this study. Expression of CD4 and Foxp3 was determined by immunohistochemistry. Antrum biopsy was obtained for detection of H. pylori, bacterial virulence factors and histopathological assessments. TGF-β1, IL-10 and FOXP3 expressions were determined by real-time polymerase chain reaction (qPCR). The numbers of CD4 + and Foxp3 + T cells as well as the expression of IL-10, TGF-β1, FOXP3, INF-γ and IL-17A in infected patients were significantly higher than the ones in uninfected patients. Also, the number of CD4 + T cells was independent on the vacuolating cytotoxin A (vacA) and outer inflammatory protein A (oipA), but it was positively correlated with cytotoxin-associated gene A (cagA). Instead, the number of Foxp3 + T cells was dependent on the vacA and oipA, but it was independent on cagA. The number of Foxp3 + T cells and the expression of IL-10, TGF-β1 and FOXP3 in infected patients with gastritis were significantly higher than the ones in infected patients with peptic ulcer. Moreover, the number of CD4 + T cells and the expression of IL-17A and INF-γ was the lowest in the gastritis patients, however, increased progressively in the peptic ulcer patients. Additionally, the numbers of CD4 + and Foxp3 + T cells as well as the expression of IL-10, TGF-β1, FOXP3 and INF-γ were positively

    To evaluate the chronic fatigue and its relation to the function of hypothalamus-pituitary-adrenal axis in patients with New York Heart Association (NYHA) functional class III-IV chronic heart failure. A total of 170 patients with NYHA functional class III-IV chronic heart failure completed MFI-20L, DUFS, and DEFS questionnaires assessing chronic fatigue and underwent echocardiography. Blood cortisol concentration was assessed at 8:00 am and 3:00 pm, and plasma N-terminal brain natriuretic pro-peptide (NT-proBNP) concentration was measured at 8:00 am. Neurohumoral investigations were repeated before cardiopulmonary exercise test and after it. The results of all questionnaires showed that 100% of patients with NYHA functional class III-IV heart failure complained of chronic fatigue. The level of overall fatigue was 54.5+/-31.5 points; physical fatigue - 56.8+/-24.6 points. Blood cortisol concentration at 8:00 am was normal (410.1+/-175.1 mmol/L) in majority of patients. Decreased concentration was only in four patients (122.4+/-15.5 mmol/L); one of these patients underwent heart transplantation. In the afternoon, blood cortisol concentration was insufficiently decreased (355.6+/-160.3 mmol/L); reaction to a physical stress was attenuated (Delta 92.9 mmol/L). Plasma NT-proBNP concentration was 2188.9+/-1852.2 pg/L; reaction to a physical stress was diminished (Delta 490.3 pg/L). All patients with NYHA class III-IV heart failure complained of daily chronic fatigue. Insufficiently decreased blood cortisol concentration in the afternoon showed that in the presence of chronic fatigue in long-term cardiovascular organic disease, disorder of a hypothalamus-pituitary-adrenal axis is involved.

    Upper gastrointestinal endoscopy (UGI-ES) and double-contrast upper gastrointestinal barium X-ray radiography (UGI-XR) are two major image-based methods to diagnose atrophic gastritis, which is mostly induced by Helicobacter pylori infection. However, there have been few studies directly comparing them. Atrophic gastritis was evaluated using the data of 962 healthy subjects who underwent UGI-ES and UGI-XR within 1 year. Based on UGI-ES and UGI-XR, 602 subjects did not have atrophic gastritis and 254 subjects did have it. Considering UGI-ES-based atrophic gastritis as the standard, sensitivity and specificity of UGI-XR-based atrophic gastritis were 92.0 % (254/276) and 92.8 % (602/649), respectively. The seven-grade Kimura-Takemoto classification of UGI-ES-based atrophic gastritis showed a strong and significant association with the four-grade UGI-XR-based atrophic gastritis. Sensitivity and specificity of serum anti-Helicobacter pylori IgG to detect UGI-ES/UGI-XR-based atrophic gastritis were 89.4 % (227/254) and 99.8 % (601/602), indicating that atrophic gastritis can be overlooked according to serum anti-Helicobacter pylori IgG alone.

    To determine the protective effect of triple viable probiotics on gastritis induced by Helicobacter pylori (H. pylori) and elucidate the possible mechanisms of protection. 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. 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).

    PubMed Central

    2013-01-01

    Human and animals studies support the idea that there is a gender-related co-morbidity of pain-related and inflammatory gastrointestinal (GI) diseases with psychological disorders. This co-morbidity is the evidence for the existence of GI-brain axis which consists of immune (cytokines), neural (vagus nerve) and neuroendocrine (HPA axis) pathways. Psychological stress causes disturbances in GI physiology, such as altered GI barrier function, changes in motility and secretion, development of visceral hypersensitivity, and dysfunction of inflammatory responses. Whether GI inflammation would exert impact on psychological behavior is not well established. We examined the effect of experimental gastritis on anxiety- and depression-like behaviors in male and female Sprague–Dawley rats, and evaluated potential mechanisms of action. Gastritis was induced by adding 0.1% (w/v) iodoacetamide (IAA) to the sterile drinking water for 7 days. Sucrose preference test assessed the depression-like behavior, open field test and elevated plus maze evaluated the anxiety-like behavior. IAA treatment induced gastric inflammation in rats of either gender. No behavioral abnormality or dysfunction of GI-brain axis was observed in male rats with IAA-induced gastritis. Anxiety- and depression-like behaviors were apparent and the HPA axis was hyperactive in female rats with IAA-induced gastritis. Our results show that gastric inflammation leads to anxiety- and depression-like behaviors in female but not male rats via the neuroendocrine (HPA axis) pathway, suggesting that the GI inflammation can impair normal brain function and induce changes in psychological behavior in a gender-related manner through the GI-to-brain signaling.

    Kaempferol (KF) is the most abundant polyphenol in tea, fruits, vegetables, and beans. However, little is known about its in vivo anti-inflammatory efficacy and mechanisms of action. To study these, several acute mouse inflammatory and nociceptive models, including gastritis, pancreatitis, and abdominal pain were employed. Kaempferol was shown to attenuate the expansion of inflammatory lesions seen in ethanol (EtOH)/HCl- and aspirin-induced gastritis, LPS/caerulein (CA) triggered pancreatitis, and acetic acid-induced writhing. © 2015 WILEY-VCH Verlag GmbH & Co.

    There are few data in the literature on microscopic gastritis and colitis in the pediatric population. The diagnosis is often made after the occurrence of complications. We report the case of a 10.5 year-old girl for whom the diagnosis was made several years after the initial symptoms. Test for infections, inflammation, and auto-immunity yielded normal results. Upper endoscopy and colonoscopy revealed an abnormal mucosa. However, histology showed microscopic inflammation and fibrotic lesions in the lamina propria, and a thick subepithelial collagenous band. This led to the diagnosis of collagenous gastritis and colitis. Budesonide treatment resulted in the cessation of diarrhea and significant weight gain. Treatment by oral budesonide indeed seems to be highly effective but relapses are frequent when the treatment is stopped. This case shows the importance of being vigilant regarding transit disorders with impact on growth kinetics. Upper endoscopy and colonoscopy need to be carried out when children have organic diarrhea with normal blood tests. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    The combination of pepsinogen, gastrin-17 and anti-H. pylori antibodies serological assays (panel test) is a non-invasive tool for the diagnosis of atrophic gastritis. However, the diagnostic reliability of this test is still uncertain. To assess the diagnostic performance of the serum panel test for the diagnosis of atrophic gastritis. Medline via PubMed, Embase, Scopus, Cochrane Library databases and abstracts of international conferences proceedings were searched from January 1995 to December 2016 using the primary keywords "pepsinogens," "gastrin," "atrophic gastritis," "gastric precancerous lesions." Studies were included if they assessed the accuracy of the serum panel test for the diagnosis of atrophic gastritis using histology according to the updated Sydney System as reference standard. Twenty studies with a total of 4241 subjects assessed the performance of serum panel test for the diagnosis of atrophic gastritis regardless of the site in the stomach. The summary sensitivity was 74.7% (95% confidence interval (CI), 62.0-84.3) and the specificity was 95.6% (95%CI, 92.6-97.4). With a prevalence of atrophic gastritis of 27% (median prevalence across the studies), the negative predictive value was 91%. Few studies with small sample size assessed the performance of the test in detecting the site of atrophic gastritis. The combination of pepsinogen, gastrin-17 and anti-H. pylori antibodies serological assays appears to be a reliable tool for the diagnosis of atrophic gastritis. This test may be used for screening subjects or populations at high risk of gastric cancer for atrophic gastritis; however, a cost-effectiveness analysis is needed. © 2017 John Wiley & Sons Ltd.

    Service provision and access to pain services vary considerably in the UK, with only a small percentage of people with chronic pain accessing specialist services. Government policy supports giving patients more choice and control over their care. Empowerment involves ensuring patients have the knowledge, skills, attitudes and self-awareness to improve the quality of their lives. As most healthcare professionals provide care to people with chronic pain at some point, it is their responsibility to prepare patients to make informed decisions about their treatment. Empowering patients to self-manage their chronic pain can lead to improved person-centred outcomes.

    Overgenerality and delay of the retrieval of autobiographical memory (AM) are well documented in a range of clinical conditions, particularly in patients with emotional disorder. The present study extended the investigation to chronic pain, attempting to identify whether the retrieval of AM in patients with chronic pain tends to be overgeneral or delayed. With an observational cross-sectional design, we evaluated the AM both in patients with chronic pain and healthy controls by Autobiographical Memory Test. Pain conditions were assessed using the pain diagnostic protocol, the short-form McGill Pain Questionnaire (SF-MPQ), and the Pain Self-Efficacy Questionnaire (PSEQ). Emotion was assessed using the Beck Depression Inventory-II (BDI-II) and the Beck Anxiety Inventory. Subjects included 176 outpatients with chronic pain lasting for at least 6 months and 170 healthy controls. 1) Compared with the healthy group, the chronic pain group had more overgeneral memories (OGMs) (F = 29.061, P < 0.01) and longer latency (F = 13.602, P < 0.01). 2) In the chronic pain group, the stepwise multiple regression models for variables predicting OGM were significant (P < 0.01). Specifically, the variance in OGM scores could be predicted by the BDI score (9.7%), pain chronicity (4.3%), PSEQ score (7.1%), and Affective Index (of SF-MPQ) score (2.7%). 3) In the chronic pain group, the stepwise multiple regression models for variables predicting latency were significant (P < 0.05). Specifically, the variance in latency could be predicted by age (3.1%), pain chronicity (2.7%), pain duration (4.3%), and PSEQ score (2.0%). The retrieval of AM in patients with chronic pain tends to be overgeneral and delayed, and the retrieval style of AM may be contributed to negative emotions and chronic pain conditions.

    Acute phlegmonous gastritis (PG) is a rare and often fatal condition mainly characterized by severe bacterial infection of the gastric wall. Case reports of PG over the past century average about 1 per year. Early diagnosis and immediate treatment are crucial to achieve positive outcomes. A 47-year-old man was referred to our hospital because of abdominal pain, high fever, and vomiting for 4 days, with aggravation for 24 hours. Physical examination revealed epigastric abdominal pain, rebound pain, and abdominal wall tightness. Abdominal CT showed thickening of the stomach wall with edema and gas. On the basis of symptoms and CT imaging findings, the patient was diagnosed with acute PG. Antibiotic therapy and operation. The patient immediately underwent an operation after conservative treatment using antibiotics proved ineffective. The whole stomach was obviously swollen, and the anterior side and posterior wall of the stomach were nigrescent necrotic. Hence, total gastrectomy was performed followed by reconstruction (roux-en-y), and pus that accumulated in the stomach wall was cultured. At postoperative broad-spectrum antibiotic coverage, the patient finally recovered. Acute PG is a rare infection of the gastric wall especially after antibiotic treatment. Given the fast progression of this disease, early recognition and immediate action are crucial to achieve positive outcomes.

    To provide an update on the impact of new information about the molecular biology of chronic leukemia and new treatment modalities available to patients. Published articles, books, and research studies. There has been significant progress in the diagnosis and management of chronic myeloid and chronic lymphocytic leukemia. New therapies provide more options for patients and longer treatment periods. With increasing treatment options and longer survival, patients with chronic myelogenous or chronic lymphocytic leukemia need increased education, support, and assistance with symptom management. Nurses caring for these patients must remain knowledgeable about new treatments and their management.

    The frequency and characteristics of headache in patients with chronic obstructive pulmonary disease (COPD) are not clear and there are only a few studies that have assessed the relationship between chronic hypoxaemia and headache. We performed this study in order to evaluate the frequency and characteristics of headache in COPD patients. A total of 119 patients, with a mean age of 63.4 +/- 8.2 years, diagnosed with moderate or severe stable COPD were included in the study. Overall 31.9% of the patients complained of headache and 45.4% were reported to have sleep disorders. There were significant effects of family history of COPD, having other systemic disorders or sleep disorders (snoring, bruxism, restless leg syndrome, etc.) and laboratory data of chronic hypoxaemia and airway obstruction on headache co-morbidity. In conclusion, possibly being a specific subtype of elderly headache, headache in patients with moderate or severe COPD is a common problem and future studies are needed to obtain more knowledge about its pathophysiological and clinical basis.

    Chronic Helicobacter pylori infection is the most common cause of gastric cancer. H. pylori induces oxidative stress while zinc deficiency results in increased sensitivity to it. In Ecuador, the prevalence of gastric cancer and zinc deficiency are high. We hypothesized that zinc deficiency in Ecuadorian people would cause increased H. pylori-induced inflammation in the gastric mucosa associated with lower tissue zinc concentrations. Three hundred and fifty-two patients with dyspepsia underwent endoscopy to obtain gastric mucosa biopsies. Diagnosis of H. pylori infection and its severity, histopathology, mucosal zinc concentration, and inflammation intensity were determined. H. pylori-infected patients with non-atrophic chronic gastritis had lower concentrations of zinc in gastric mucosa than uninfected patients with the same type of gastritis (251.3 +/- 225.3 vs. 426.2 +/- 279.9 ng/mg of protein; p = .016). Considering all patients, the more severe the H. pylori infection, the higher the percentage of subjects with infiltration by polymorphonuclear (PMN) cells (p = .0001). Patients with high PMN infiltration had lower mucosal zinc concentrations than patients with low PMN infiltration (35.2 +/- 20.7 vs. 242.9 +/- 191.8 ng/mg of protein; p = .021). The degree of inflammation in H. pylori-induced gastritis appears to be modulated by gastric tissue zinc concentrations.

    Respiratory muscle strength is one parameter that is currently proposed to be affected in patients with chronic neck pain. This study was aimed at examining whether patients with chronic neck pain have reduced respiratory strength and with which neck pain problems their respiratory strength is associated. In this controlled cross-sectional study, 45 patients with chronic neck pain and 45 healthy well-matched controls were recruited. Respiratory muscle strength was assessed through maximal mouth pressures. The subjects were additionally assessed for their pain intensity and disability, neck muscle strength, endurance of deep neck flexors, neck range of movement, forward head posture and psychological states. Paired t-tests showed that patients with chronic neck pain have reduced Maximal Inspiratory (MIP) (r = 0.35) and Maximal Expiratory Pressures (MEP) (r = 0.39) (P < 0.05). Neck muscle strength (r > 0.5), kinesiophobia (r < -0.3) and catastrophizing (r < -0.3) were significantly associated with maximal mouth pressures (P < 0.05), whereas MEP was additionally negatively correlated with neck pain and disability (r < -0.3, P < 0.05). Neck muscle strength was the only predictor that remained as significant into the prediction models of MIP and MEP. It can be concluded that patients with chronic neck pain present weakness of their respiratory muscles. This weakness seems to be a result of the impaired global and local muscle system of neck pain patients, and psychological states also appear to have an additional contribution. Clinicians are advised to consider the respiratory system of patients with chronic neck pain during their usual assessment and appropriately address their treatment. Copyright © 2012 Elsevier Ltd.

    The incidence and nature of acute secondary irradiation esophagitis was studied in a series of 38 patients undergoing 60Co teletherapy for carcinoma of the lung. Thirty-four patients were male and four female, with ages ranging from 38 to 78 years. The mediastinum being irradiated in the process, all the patients underwent endoscopy for signs of esophagitis and/or gastritis after a dose of 30-40 Gy was delivered to the esophagus. Eighteen patients complained of dysphagia, but only in 12 of them did endoscopy show esophagitis. Of the remaining patients without complaints five had endoscopic signs of esophagitis. Gastritis was found inmore » 18 cases and confirmed histologically in 14. In 17 cases, esophagitis and/or gastritis were confirmed histologically. It is believed that there is a fairly close correlation among clinical, endoscopic, and histological findings to support the claim that esophagitis in these patients is radiation induced. However, the cause of gastritis is not well understood. Data in the literature suggest that nonsteroid anti-inflammatory agents can act as prophylactic means of preventing radiation esophagitis.« less

    Gastric juice plays a crucial role in the physiology of the stomach. The aim of this study is to evaluate associations among the pH of gastric juice, atrophic gastritis (AG), intestinal metaplasia (IM), pepsinogen, and Helicobacter pylori infection. Gastric biopsies and juice were collected from 46 subjects who underwent endoscopies at Seoul National University Bundang Hospital between November 2011 and March 2013. H. pylori , AG and IM were evaluated, and pepsinogen I or II, I/II ratio, and interleukin (IL)-1β levels were measured. The mean pH of gastric juice was higher in the H. pylori -positive group (n=17) than that in the H. pylori -negative group (n=29) (4.54 vs 2.46, p=0.002). When patients were divided into pH <3 (n=28) and pH ≥3 (n=18) groups, H. pylori was lower in the pH <3 group (21.4%) than in the pH ≥3 group (61.1%) (p=0.007). The pH ≥3 group demonstrated AG and IM more frequently than the pH <3 group in the body (p=0.047 and p=0.051, respectively) but not in the antrum. There were no differences in pepsinogen I or II, I/II ratio, and IL-1β levels between the two groups. There is a relationship between chronic H. pylori infection and gastric juice pH ≥3, which may originate from AG and IM in the body.

    Colonising Campylobacter pyloridis were identified histologically in gastric biopsy specimens from 89% of 83 patients with non-ulcer dyspepsia and chronic gastritis, but not in 58 dyspeptic patients with normal mucosa. The presence and population density of organisms was associated with the presence of intraepithelial neutrophils. In vivo coating of the organisms by host immunoglobulin was investigated by immunoperoxidase staining of IgA, IgG, and IgM in 54 biopsy specimens. IgA coated bacteria were seen in all cases of active gastritis, and in 60% of biopsy specimens without intraepithelial neutrophils. Coating with IgG or IgM, or both, was correlated with activity of gastritis and was rarely seen in the absence of a neutrophil infiltrate. Images PMID:3528230

    Chronic obstructive pulmonary disease is the fourth leading cause of mortality worldwide. It is defined as a persistent airflow limitation usually progressive and not fully reversible to treatment. The diagnosis of chronic obstructive pulmonary disease and severity of disease is confirmed by spirometry. Chronic obstructive pulmonary disease produces electrical changes in the heart which shows characteristic electrocardiogram pattern. The aim of this study was to observe and evaluate diagnostic values of electrocardiogram changes in chronic obstructive pulmonary disease patients with no other comorbidity. We analyzed 110 electrocardiogram findings in clinically stable chronic obstructive pulmonary disease patients and evaluated the forced expiratory volume in the first second, ratio of forces expiratory volume in the first second to the fixed vital capacity, chest radiographs and electrocardiogram changes such as p wave height, QRS axis and voltage, right bundle branch block, left bundle branch block, right ventricular hypertrophy, T wave inversion in leads V1-V3, S1S2S3 syndrome, transition zone in praecordial lead and QT interval. We found electrocardiogram changes in 64% patients, while 36% had normal electrocardiogram. The most frequent electrocardiogram changes observed were transition zone (76.36%) low QRS (50%) and p pulmonale (14.54%). Left axis deviation was observed in 27.27% patients. Diagnostic values of electrocardiogram in patients with chronic obstructive pulmonary disease suggest that chronic obstructive pulmonary disease patients should be screened electrocardiographically in addition to other clinical investigations.

    According to Prochaska's transtheoretical model, the Freiburg Questionnaire stages of chronic pain management (FQ-STAPM) were used to classify chronic back patients into 4 distinct motivational stages. The FQ-STAMP was completed by 163 chronic back pain patients. Pain chronicity was measured by the Mainz Pain Staging System; pain intensity was measured by the numeric rating scale. Healthcare system expenses were considered as number of consulted physicians, number of stays in hospital, and number of rehabilitation programs. As psychometric tests, the lower pain disability index (PDI), the Hospital Anxiety and Depression Scale (HADS), and a quality of life score (SF36) were used. Patients were in the following motivational stages: precontemplation in 30%, preparation in 19%, action in 30%, maintenance in 21%. The intensity of pain in the precontemplation stage patients was significantly higher compared to patients in the maintenance stage. A lower pain chronicity was related to a significantly higher motivation. Moreover, there was a significant increase in healthcare system expenses by the lesser motivated patients. Patients in the maintenance stage used significantly less opioids than patients in the precontemplation stage. The higher motivated patients had a significantly lower PDI, a significantly lower HADS, and a significantly higher quality of life compared to less motivated patients. The study indicates that the FQ-STAPM might be a useful tool to classify chronic back pain patients and to work out a strategy together with the patient relevant to the outcome of pain management among chronic back pain patients.

    New selective and more potent drugs for the cure of chronic phase chronic myeloid leukemia patients are now available: physicians in some countries must decide the best option, selecting one of the drugs available. What the main prognostic factors are in order to make this selection remains a matter of discussion. Introducing a 'holistic approach' for the first time in chronic myeloid leukemia, as practiced in other diseases, and looking at the patient in a complete picture, considering several variables, such as comorbidities, age, concomitant drugs, lifestyle and patient expectations, may be of help to understand, patient by patient, the best therapeutic strategy.

    2014-01-01

    Background Gastritis cystica profunda (GCP) is an uncommon disease characterized by multiple cystic gastric glands within the submucosa of the stomach. Case description Here, we present a case of a 63-year-old man with intermittent epigastric discomfort in whom gastroscopy revealed multiple irregular elevated nodular lesions with smooth surfaces at the anterior of the antrum. Surgical resection of the nodular lesions was performed, and the diagnosis of gastritis cystica profunda (GCP) was confirmed by histological examination. Another elevated nodular lesion approximately 10 mm in diameter with an ulcer was found on the gastric side of the remnant stomach near the resection side from 6 to 24 months after the surgical resection. Endoscopic ultrasonography (EUS) and repeated biopsies of the new elevated lesion were performed. Homogeneous, anechoic masses originating from the submucosa without gastric adenocarcinoma in histological examination showed GCP recurrence may occur. Conclusions We report a case of GCP recurrence within 6 months after surgical resection. GCP should be considered in the differential diagnosis of elevated lesions in the stomach. PMID:24885818

    There are a variety of dermatological diseases that are more commonly seen in patients with chronic kidney disease (CKD) and renal transplants than the general population. Directory of Open Access Journals (DOAJ), Google Scholar, Pubmed (NLM), LISTA (EBSCO) and Web of Science has been searched. Some cutaneous diseases are clearly unique to this population. Of them, Lindsay's Nails, xerosis cutis, dryness of the skin, nephrogenic systemic fibrosis and acquired perforating dermatosis have been described in chronic kidney disease patients. The most common malignancy found in all transplant recipients is non-melanoma skin cancer. It is important for patients and physicians to recognize the manifestations of skin disease in patients suffering from chronic kidney disease to mitigate the morbidity associated with these conditions.

    BACKGROUND Helicobacter pylori is considered to be a pathogen responsible for gastritis and peptic ulcers, and a risk factor for gastric cancer. A periodontal pocket in the teeth of individuals with chronic periodontitis may function as a reservoir for H pylori. OBJECTIVE: The present study was undertaken to evaluate whether the presence of H pylori in the dental plaque of patients with and without periodontitis correlates with gastric involvement. METHODS: A total of 101 patients with dyspepsia were included in the present study. Subjects were divided into periodontitis and non-periodontitis groups. For the detection of H pylori in dental plaque, samples were collected from two teeth using a periodontal curette. Subgingival plaque was obtained by inserting two sterile paper points into periodontal pockets for 20 s. This was followed by an upper gastrointestinal endoscopy and antral biopsies. RESULTS: Sixty-five per cent of patients had dental plaque positive for H pylori and more than 50% harboured the bacteria in their stomach. Periodontitis patients had a significantly higher percentage of H pylori in their dental plaque (79% versus 43%; P<0.05) and the stomach (60% versus 33%; P<0.05) than patients with no periodontitis. Additionally, 78% of patients from the periodontitis group versus only 30% from the nonperiodontitis group had a positive test result for the coexistence of H pylori in both dental plaque and the stomach. CONCLUSION: Patients with poor oral hygiene have a higher prevalence of H pylori in dental plaque and in the stomach. This finding suggests that the oral cavity may be a reservoir for H pylori, and potentially a source of transmission or reinfection. PMID:19319381

    Medicinal cannabis use is topical in the media in Ireland. A recent Health Products Regulatory Authority review, however, has recommended against its use for patients with chronic pain. This is despite evidence for its effectiveness in this patient's cohort and the inadequate pain management of these patients. The aim of this study was to evaluate the attitudes of Irish patients with chronic pain towards medicinal cannabis. After institutional ethics committee approval, a 12-item questionnaire (excluding demographics) was randomly assigned to patients attending a chronic pain clinic (University Hospital Limerick). The questionnaire was designed to incorporate patient's attitudes on a variety of medicinal cannabis related topics. Ninety-six adult patients were surveyed. 88.54% agreed that cannabis should be legalised for chronic pain medicinal purposes. 80.21% believed it would have health benefits for them and 73.96% agreed it would be socially acceptable to use cannabis for this purpose. 33.33% perceived cannabis to be addictive while 68.75% would be willing to try it if prescribed by a medical professional. The study highlights the attitudes of chronic pain patients in Ireland towards medicinal cannabis. It shows their desire to have medical cannabis legalised for chronic pain and that they view it as a reasonable pain management option.

    Irsogladine maleate, an enhancer of gastric mucosal protective factors, has demonstrated its efficacy for various gastric mucosal injuries. The aim of this study was to evaluate the efficacy and safety of irsogladine for prevention of nonsteroidal anti-inflammatory drugs (NSAIDs) or aspirin-induced peptic ulcer and gastritis. In this multicenter, randomized, double-blind, exploratory clinical trial, 100 patients over 50 years of age who needed continuous NSAIDs or aspirin for more than 8 weeks were randomly assigned to either test group (irsogladine maleate 2 mg, twice daily, 39 patients for full analysis) or placebo group (37 patients for full analysis). Primary outcomes were incidence of peptic ulcer and ratio of modified Lanza score (MLS) 2 to 4. Secondary outcome was the number of acute erosions confirmed by endoscopy at 8 weeks. Adverse effects were also compared. There were no significant differences in gastric protective effects between test and placebo groups. However, two cases of peptic ulcer in the placebo group but none in the test group were observed. These two cases of peptic ulcer were Helicobacter pylori-negative. In addition, H. pylori-negative group showed significant changes in MLS score (p = 0.0247) and edema score (p = 0.0154) after the treatment compared to those before treatment in the test group. There was no significant difference in adverse events between the two groups. The efficacy of irsogladine maleate was found in H. pylori-negative group, suggesting its potential as a protective agent against NSAIDs or aspirin-induced peptic ulcer and gastritis.

    Helicobacter pylori chronic infection is associated with chronic gastritis, peptic ulcer, and gastric cancer. Cytotoxin-associated gene A (cagA)-positive H. pylori strains increase the risk of gastric pathology. The carcinogenic potential of CagA is linked to its polymorphic EPIYA motif variants. The goals of this study were to investigate the frequency of cagA-positive Helicobacter pylori in Mexican patients with gastric pathologies and to assess the association of cagA EPIYA motif patterns with peptic ulcer and gastric cancer. A total of 499 patients were studied; of these, 402 had chronic gastritis, 77 had peptic ulcer, and 20 had gastric cancer. H. pylori DNA, cagA, and the EPIYA motifs were detected in total DNA from gastric biopsies by PCR. The type and number of EPIYA segments were determined by the electrophoretic patterns. To confirm the PCR results, 20 amplicons of the cagA 3' variable region were sequenced, and analyzed in silico, and the amino acid sequence was predicted with MEGA software, version 5. The odds ratio (OR) was calculated to determine the associations between the EPIYA motif type and gastric pathology and between the number of EPIYA-C segments and peptic ulcers and gastric cancer. H. pylori DNA was found in 287 (57.5%) of the 499 patients, and 214 (74%) of these patients were cagA-positive. The frequency of cagA-positive H. pylori was 74.6% (164/220) in chronic gastritis patients, 73.6% (39/53) in peptic ulcer patients, and 78.6% (11/14) in gastric cancer patients. The EPIYA-ABC pattern was more frequently observed in chronic gastritis patients (79.3%, 130/164), while the EPIYA-ABCC sequence was more frequently observed in peptic ulcer (64.1%, 25/39) and gastric cancer patients (54.5%, 6/11). However, the risks of peptic ulcer (OR = 7.0, 95% CI = 3.3-15.1; p < 0.001) and gastric cancer (OR = 5.9, 95% CI = 1.5-22.1) were significantly increased in individuals who harbored the EPIYA-ABCC cagA gene pattern. cagA-positive H

    Morbid obesity treatment through vertical gastroplasty Roux-en-Y gastric bypass initially used a contention ring. However, this technique may create conditions to the development of potentially malign alterations in the gastric mucosa. Although effective and previously performed in large scale, this technique needs to be better evaluated in long-term studies regarding alterations caused in the gastric mucosa. To analyze the preoperative and postoperative endoscopic, histological and cell proliferation findings in the gastric antrum and body mucosa of patients submitted to the Roux-en-Y gastric bypass with a contention ring. We retrospectively evaluated all patients submitted to Roux-en-Y gastric bypass with a contention ring with more than 60 months of postoperative follow-up. We compared the preoperative (gastric antrum and body) and postoperative (gastric pouch) gastric mucosa endoscopic findings, cell proliferation index and H. pylori prevalence. We evaluated cell proliferation through Ki-67 antibody immunohistochemical expression. In the study period, 33 patients were operated with the Roux-en-Y gastric bypass using a contention ring. We found a chronic gastritis rate of 69.7% in the preoperative period (gastric antrum and body) and 84.8% in the postoperative (gastric pouch). H. pylori was present in 18.2% of patients in the preoperative period (gastric antrum and body) and in 57.5% in the postoperative (gastric pouch). Preoperative cell proliferation index was 18.1% in the gastric antrum and 16.2% in the gastric body, and 23.8% in the postoperative gastric pouch. The postoperative cell proliferation index in the gastric pouch was significantly higher (P=0.001) than in the preoperative gastric antrum and body. Higher cell proliferation index and chronic gastritis intensity were significantly associated to H. pylori presence (P=0.001 and P=0.02, respectively). After Roux-en-Y gastric bypass with contention ring, there was a higher chronic gastritis incidence and

    It is known that hepatitis C virus (HCV) related to chronic liver disease may be associated with various immunological disorders, among these disorders are mixed cryoglobulinemia, serum antinuclear antibodies, antismooth muscle antibodies and liver/kidney microsomal antibody type 1 (LKM1). However, the actual prevalence and pathogenic role of these disorders in patients with chronic hepatitis C are unclear. It was our aim to estimate the prevalence of different autoimmune antibodies in cases of hepatitis C chronic liver disease and to assess if such changes have any clinical significance. A total of 30 chronic hepatitis C patients (22 males and 8 females) with a mean age of 43.5 +/- 6.7 years, all patients were ELISA II positive, HCV RNA PCR positive and HbsAg negative, with elevated ALT more than 2 folds of the normal, in addition to 20 healthy controls of matched age and sex were tested for rheumatoid factor, cryoglobulin, antinuclear antibody, antismooth muscle antibody, antimitochondrial antibody and LKM1. The rheumatoid factor was present in 18 (60%) of the HCV Ab +ve patients and in 1 (5%) of the controls (p < 0.0002), cryoglobulins were present in 4 (13.3%) of the patients and not detected in the controls (p > 0.24), antinuclear antibody was positive in 4 (13.3%) of the patients and in 1 (5%) of the controls (p > 0.6), antismooth muscle antibody was positive in 1 (3.3%) of the patients and not detected in any of the controls, the antimitochondrial antibody and LKM1 were not detected in both the patients and the controls. In conclusion, we can see that chronic hepatitis C patients show prevalence of some autoimmune antibodies and their presence is not associated with any implication on the clinical presentation.

    Although nondialyzed, chronically uremic patients and patients undergoing maintenance hemodialysis often show evidence for wasting and calorie malnutrition and have low dietary energy intakes, their energy expenditure has never been systematically evaluated. It is possible that low energy intakes are an adaptive response to reduced energy needs; alternatively, energy expenditure could be normal or high and the low energy intakes would be inappropriate. Energy expenditure was therefore measured by indirect calorimetry in 12 normal individuals, 10 nondialyzed patients with chronic renal failure, and 16 patients undergoing maintenance hemodialysis. Energy expenditure was measured in the resting state, during quiet sitting, during controlled exercise on an exercise bicycle, and for four hours after ingestion of a test meal. Resting energy expenditure (kcal/min/1.73 m2) in the normal subjects, chronically uremic patients and hemodialysis patients was, respectively, 0.94 +/- 0.24 (SD), 0.91 +/- 0.20, and 0.97 +/- 0.10. There was also no difference among the three groups in energy expenditure during sitting, exercise, or the postprandial state. Within each group, energy expenditure during resting and sitting was directly correlated. During bicycling, energy expenditure was directly correlated with work performed, and the regression equation for this relationship was similar in each of the three groups. These findings suggest that for a given physical activity, energy expenditure in nondialyzed, chronically uremic patients and maintenance hemodialysis patients is not different from normal. The low energy intakes of many of these patients may be inadequate for their needs.

    Context: There are a variety of dermatological diseases that are more commonly seen in patients with chronic kidney disease (CKD) and renal transplants than the general population. Evidence Acquisitions: Directory of Open Access Journals (DOAJ), Google Scholar, Pubmed (NLM), LISTA (EBSCO) and Web of Science has been searched. Results: Some cutaneous diseases are clearly unique to this population. Of them, Lindsay’s Nails, xerosis cutis, dryness of the skin, nephrogenic systemic fibrosis and acquired perforating dermatosis have been described in chronic kidney disease patients. The most common malignancy found in all transplant recipients is non-melanoma skin cancer. Conclusions: It is important for patients and physicians to recognize the manifestations of skin disease in patients suffering from chronic kidney disease to mitigate the morbidity associated with these conditions.

    Background Chronically critically ill patients often have high costs of care and poor outcomes and thus might benefit from a disease management program. Objectives To evaluate how adding a disease management program to the usual care system affects outcomes after discharge from the hospital (mortality, health-related quality of life, resource use) in chronically critically ill patients. Methods In a prospective experimental design, 335 intensive care patients who received more than 3 days of mechanical ventilation at a university medical center were recruited. For 8 weeks after discharge, advanced practice nurses provided an intervention that focused on case management and interdisciplinary communication to patients in the experimental group. Results A total of 74.0% of the patients survived and completed the study. Significant predictors of death were age (P = .001), duration of mechanical ventilation (P = .001), and history of diabetes (P = .04). The disease management program did not have a significant impact on health-related quality of life; however, a greater percentage of patients in the experimental group than in the control group had “improved” physical health-related quality of life at the end of the intervention period (P = .02). The only significant effect of the intervention was a reduction in the number of days of hospital readmission and thus a reduction in charges associated with readmission. Conclusion The intervention was not associated with significant changes in any outcomes other than duration of readmission, but the supportive care coordination program could be provided without increasing overall charges.

    While transradial approach to conduct percutaneous coronary interventions offers multiple advantages, the procedure can cause radial artery damage and occlusion. Because radial artery is the preferred site for the creation of an arteriovenous fistula to provide dialysis, patients with chronic kidney disease are particularly dependent on radial artery for their long-term survival. In this retrospective study, we investigated the prevalence of chronic kidney disease in patients undergoing coronary interventions via radial artery. Stage of chronic kidney disease was based on estimated glomerular filtration rate and National Kidney Foundation - Kidney Disease Outcomes Quality Initiative guidelines. A total of 497 patients undergoing transradial percutaneous coronary interventions were included. Over 70.4% (350/497) of the patients had chronic kidney disease. Stage II chronic kidney disease was observed in 243 (69%) patients (estimated glomerular filtration rate = 76.0 ± 8.4 mL/min). Stage III was observed in 93 (27%) patients (estimated glomerular filtration rate = 49 ± 7.5 mL/min). Stage IV chronic kidney disease was observed in 5 (1%) patients (estimated glomerular filtration rate = 25.6 ± 4.3 mL/min) and Stage V chronic kidney disease was observed in 9 (3%) patients (estimated glomerular filtration rate = 9.3 ± 3.5 mL/min). Overall, 107 of 350 patients (30%) had advanced chronic kidney disease, that is, stage III-V chronic kidney disease. Importantly, 14 of the 107 (13%) patients had either stage IV or V chronic kidney disease. This study finds that nearly one-third of the patients undergoing transradial percutaneous coronary interventions have advanced chronic kidney disease. Because many of these patients may require dialysis, the use of radial artery to conduct percutaneous coronary interventions must be carefully considered in chronic kidney disease population.

    To assess severity of cognitive disorders in chronic mercury intoxication, the authors performed claster and discrimination analysis of neuropsychologic and neurophysiologic research data from workers exposed to mercury during long length of service, from patients with early and marked stages of chronic mercurial intoxication. Cognitive disorders in chronic mercurial intoxication have three severity degrees, in the light degree disorders patients demonstrate lower amplitude of cognitive evoked potentials, poor long-term memory and associative thinking. Moderate cognitive disorders are characterized by decreased visual, long-term memory, concentration of attention, poor optic and spatial gnosis. Marked cognitive disorders with chronic mercurial intoxication present with more decreased long-term, short-term, picturesque memory, poor intellect, optic and spatial gnosis and associative thinking.

    To determine the positive subdomain numbers and distribution of the UPOINT classification in chronic prostatitis and to compare the erectile dysfunction (ED) pattern. From 2008 to 2013, 839 patients with symptomatic chronic prostatitis or chronic pelvic pain syndrome were included in this study. The correlation between UPOINT domains and National Institutes of Health chronic prostatitis symptom index (NIH-CPSI) total score, subscores, and the 5-item International Index of Erectile Function scores were evaluated retrospectively. The mean patient age was calculated as 37.7 ± 7.4 (range 21-65). The average total NIH-CPSI score was determined as 9.07 (range 1-40) and the average positive UPOINT subdomain number was determined as 2.87 ± 0.32 (range 1-6). Subdomain patient numbers and rates were calculated as 529 urinary (63%), 462 psychosocial (55%), 382 organ specific (45%), 290 infection (34%), 288 neurological or systemic (34%), and 418 tenderness (skeletal muscle) (50%), respectively. It was determined that ED, determining the subdomain of sexual dysfunction in patients, was positive in a total of 326 (39.9%) patients, with 220 patients having mild (26.2%), 76 mild to moderate (9.1%), 19 moderate (2.3%), and 5 with severe (0.6%) ED. A statistically significant correlation was not determined between the 5-item International Index of Erectile Function score and UPOINT subdomain number and NIH-CPSI score. It has been determined that although there is a strong and significant correlation between UPOINT classification and NIH-CPSI score in Turkish patients with chronic prostatitis or chronic pelvic pain syndrome, the inclusion of ED as an independent subdomain to the UPOINT classification is not statistically significant.

    The main treatment strategies for chronic pancreatitis in young patients include therapeutic endoscopic retrograde cholangio-pancreatography (ERCP) intervention and surgical intervention. Therapeutic ERCP intervention is performed much more extensively for its minimally invasive nature, but a part of patients are referred to surgery at last. Historical and follow-up data of 21 young patients with chronic pancreatitis undergoing duodenum-preserving total pancreatic head resection were analyzed to evaluate the outcomes of therapeutic ERCP intervention and surgical intervention in this study. The surgical complications of repeated therapeutic ERCP intervention and surgical intervention were 38% and 19% respectively. During the first therapeutic ERCP intervention to surgical intervention, 2 patients developed diabetes, 5 patients developed steatorrhea, and 5 patients developed pancreatic type B pain. During the follow-up of surgical intervention, 1 new case of diabetes occurred, 1 case of steatorrhea recovered, and 4 cases of pancreatic type B pain were completely relieved. In a part of young patients with chronic pancreatitis, surgical intervention was more effective than therapeutic ERCP intervention on delaying the progression of the disease and relieving the symptoms.

    During Helicobacter pylori (H. pylori) infection CD4 + T cells in the gastric lamina propria are hyporesponsive and polarized by Th1/Th17 cell responses controlled by Treg cells. The objective of this study was to determine the number of Th17 cells in gastric mucosa of patients with gastritis and peptic ulcer and determined the relationship between main virulence factor of H. pylori and Th17 cells. A total of 89 H. pylori-infected gastritis patients, 63 H. pylori-infected peptic ulcer patients and 48 H. pylori-negative non-ulcer dysplasia patients were enrolled in this study. The number of Th17 was determined by immunohistochemistry. IL-8 and IL-17A expressions were determined by real-time polymerase chain reaction (qPCR). Also, the grade of chronic and active inflammation was investigated for involvement according to the density of neutrophils and mononuclear in gastric mucosal crypts, from one to all crypts. The number of Th17 cells and the expression of IL-8 and IL-17A in infected patients were significantly higher than uninfected subjects. The number of Th17 cells and the expression of IL-8 and IL-17A in infected patients with peptic ulcer were significantly higher than patients with gastritis. Additionally, the numbers of Th17 cells as well as the expression of IL-8 and IL-17A were positively correlated with the degree of H. pylori density in infected patients with peptic ulcer, while this correlation was negative in infected patients with gastritis. The numbers of Th17 cells as well as the expression of IL-8 and IL-17A were positively correlated with the degree of chronic inflammation. The predominant Th17 cell responses may play a role in the pathogenesis of peptic ulcers disease in infected patients. Copyright © 2018 Elsevier B.V. All rights reserved.

    Objective The objective of this study is to investigate the prevalence and disparity of chronic opioid usage in surgical patients and the potential risk factors associated with chronic opioid usage. Background Chronic opioid usage is common in surgical patients; however, the characteristics of opioid usage in surgical patients is unclear. In this study, we hypothesize that the prevalence of chronic opioid usage in surgical patients is high, and that significant disparities may exist among different surgical populations. Methods Data of opioid usage in outpatients among different surgical services were extracted from the electronic medical record database. Patient demographics, clinical characteristics of sex, age, race, body mass index (BMI), specialty visited, duration of opioid use, and opioid type were collected. Chronic opioid users were defined as patients who had been recorded as taking opioids for at least 90 days determined by the first and last visit dates under opioid usage during the investigation. Results There were 79,123 patients included in this study. The average prevalence is 9.2%, ranging from 4.4% to 23.8% among various specialties. The prevalence in orthopedics (23.8%), neurosurgery (18.7%), and gastrointestinal surgery (14.4%) ranked in the top three subspecialties. Major factors influencing chronic opioid use include age, Ethnicitiy, Subspecialtiy, and multiple specialty visits. Approximately 75% of chronic users took opioids that belong to the category II Drug Enforcement Administration classification. Conclusions Overall prevalence of chronic opioid usage in surgical patients is high with widespread disparity among different sex, age, ethnicity, BMI, and subspecialty groups. Information obtained from this study provides clues to reduce chronic opioid usage in surgical patients. PMID:27163960

    The aim of this study was to investigate the 4977 and 7400 bp deletions of mitochondrial DNA in patients with chronic suppurative otitis media and to indicate the possible association of mitochondrial DNA deletions with chronic suppurative otitis media. Thirty-six patients with chronic suppurative otitis media were randomly selected to assess the mitochondrial DNA deletions. Tympanomastoidectomy was applied for the treatment of chronic suppurative otitis media, and the curettage materials including middle ear tissues were collected. The 4977 and 7400 bp deletion regions and two control regions of mitochondrial DNA were assessed by using the four pair primers. DNA was extracted from middle ear tissues and peripheral blood samples of the patients, and then polymerase chain reactions (PCRs) were performed. PCR products were separated in 2 % agarose gel. Seventeen of 36 patients had the heterozygote 4977 bp deletion in the middle ear tissue but not in peripheral blood. There wasn't any patient who had the 7400 bp deletion in mtDNA of their middle ear tissue or peripheral blood tissue. The patients with the 4977 bp deletion had a longer duration of chronic suppurative otitis media and a higher level of hearing loss than the others (p < 0.01). Long time chronic suppurative otitis media and the reactive oxygen species can cause the mitochondrial DNA deletions and this may be a predisposing factor to sensorineural hearing loss in chronic suppurative otitis media. An antioxidant drug as a scavenger agent may be used in long-term chronic suppurative otitis media.

    The indigenous bacterial microbiome of the stomach, including lactobacilli, is vital in promoting colonization resistance against Candida albicans. However, there are gaps in our understanding about C. albicans gastric colonization versus disease, especially during the postantibiotic recovery phase. This study compared the gastric responses to C. albicans strains CHN1 and SC5314 in microbiome-disturbed and germfree mice to elucidate the contribution of the indigenous microbiota in C. albicans colonization versus disease and yeast-bacterium antagonism during the post-cefoperazone recolonization period. C. albicans can prevent the regrowth of Lactobacillus spp. in the stomach after cefoperazone and promote increased colonization by Enterococcus spp. Using a culture-independent analysis, the effects of oral cefoperazone on the gastric bacterial microbiota were observed to last at least 3 weeks after the cessation of the antibiotic. Disturbance of the gastric bacterial community by cefoperazone alone was not sufficient to cause gastritis, C. albicans colonization was also needed. Gastritis was not evident until after day 7 in cefoperazone-treated infected mice. In contrast, in germfree mice which lack a gastric microbiota, C. albicans induced gastric inflammation within 1 week of inoculation. Therefore, the gastric bacterial community in cefoperazone-treated mice during the first week of postantibiotic recolonization was sufficient to prevent the development of gastritis, despite being ineffective at conferring colonization resistance against C. albicans. Altogether, these data implicate a dichotomy between C. albicans colonization and gastric disease that is bacterial microbiome dependent. PMID:21986629
