    Gastroesophageal reflux disease is one of the commonest chronic conditions in the western world and its prevalence is increasing worldwide. The discovery of the acid pocket explained the paradox of acid reflux occurring more frequently in the postprandial period despite intragastric acidity being low due to the buffering effect of the meal. The acid pocket was first described in 2001 when it was detected as an area of low pH immediately distal to the cardia using dual pH electrode pull-through studies 15 minutes after a meal. It was hypothesized that there was a local pocket of acid close to the gastroesophageal junction that escapes the buffering effect of the meal, and that this is the source of postprandial acidic reflux. The presence of the acid pocket has been confirmed in other studies using different techniques including high-resolution pHmetry, Bravo capsule, magnetic resonance imaging, and scintigraphy. This review aims to describe what we know about the acid pocket including its length, volume, fluid constituents, and its relationship to the lower esophageal sphincter and squamocolumnar junction. We will discuss the possible mechanisms that lead to the formation of the acid pocket and examine what differences exist in patients who suffer from acid reflux. Treatments for reflux disease that affect the acid pocket will also be discussed.

    Esophageal motility has been well studied in gastroesophageal reflux disease (GERD) and acid reflux, but not in nonacid reflux. Consecutive patients who had both 24-h multichannel intraluminal impedance-pH (MII-pH) and esophageal motility tests for suspected GERD were studied. Patients were grouped into nonacid refluxers, acid refluxers, and nonrefluxers based on positive symptom correlation and objective findings of acid reflux. Of 96 patients enrolled, 21 patients (22%) were nonacid refluxers, 44 patients (46%) were acid refluxers, and 31 patients (32%) had no objective evidence of reflux. Normal motility was recorded in 86% of nonacid refluxers, 71% of acid refluxers, and 60% of nonrefluxers. Ineffective esophageal motility was seen in 24% of acid refluxers, and 5% of nonacid refluxers (P = 0.11). Symptomatic nonacid reflux events comprised 22% of patients studied for GERD symptoms by MII-pH. Esophageal motility in nonacid reflux is normal 86% of the time.

  3. How reflux causes symptoms: reflux perception in gastroesophageal reflux disease.

    In gastroesophageal reflux disease (GERD) symptoms arise due to reflux of gastric content into the oesophagus. However, the relation between magnitude and onset of reflux and symptom generation in GERD patients is far from simple; gastroesophageal reflux occurs several times a day in everyone and the majority of reflux episodes remains asymptomatic. This review aims to address the question how reflux causes symptoms, focussing on factors leading to enhanced reflux perception. We will highlight esophageal sensitivity variance between subtypes of GERD, which is influenced by peripheral sensitization of primary afferents, central sensitization of spinal dorsal horn neurons, impaired mucosal barrier function and genetic factors. We will also discuss the contribution of specific refluxate characteristics to reflux perception, including acidity, and the role of bile, pepsin and gas and proximal extent. Further understanding of reflux perception might improve GERD treatment, especially in current partial responders to therapy.

    BACKGROUND—Bile acid toxicity has been shown in the gastric, colonic, and hepatic tissues; the effect on oesophageal mucosa is less well known. 
AIMS—To determine the spectrum of bile acids refluxing in patients with gastro-oesophageal reflux disease and its relation to oesophageal pH using a new technique of combined oesophageal aspiration and pH monitoring. 
METHODS—Ten asymptomatic subjects and 30 patients with symptoms of gastro-oesophageal reflux disease (minimal mucosal injury, erosive oesophagitis (grade 2 or 3 Savary-Miller), Barrett's oesophagus/stricture; n=10 in each group) underwent 15 hour continuous oesophageal aspiration with simultaneous pH monitoring. Bile acid assay of the oesophageal samples was performed using modified high performance liquid chromatography. 
RESULTS—The peak bile acid concentration and DeMeester acid scores were significantly higher in the patients with oesophagitis (median bile acid concentration 124 µmol/l; acid score 20.2) and Barrett's oesophagus/stricture (181 µmol/l; 43.3) than patients with minimal injury (14 µmol/l; 12.5) or controls (0 µmol/l; 11.1). The predominant bile acids detected were cholic, taurocholic, and glycocholic acids but there was a significantly greater proportion of secondary bile acids, deoxycholic and taurodeoxycholic acids, in patients with erosive oesophagitis and Barrett's oesophagus/stricture. Although bile acid reflux episodes occurred at variable pH, a temporal relation existed between reflux of taurine conjugates and oesophageal acid exposure (r=0.58, p=0.009). 
CONCLUSION—Toxic secondary bile acid fractions have been detected in patients with extensive mucosal damage. Mixed reflux is more harmful than acid reflux alone with possible toxic synergism existing between the taurine conjugates and acid.

  5. Lower pH values of weakly acidic refluxes as determinants of heartburn perception in gastroesophageal reflux disease patients with normal esophageal acid exposure.

    Multichannel impedance pH monitoring has shown that weakly acidic refluxes are able to generate heartburn. However, data on the role of different pH values, ranging between 4 and 7, in the generation of them are lacking. The aim of this study was to evaluate whether different pH values of weakly acidic refluxes play a differential role in provoking reflux symptoms in endoscopy-negative patients with physiological esophageal acid exposure time and positive symptom index and symptom association probability for weakly acidic refluxes. One hundred and forty-three consecutive patients with gastroesophageal reflux disease, nonresponders to proton pump inhibitors (PPIs), were allowed a washout from PPIs before undergoing: upper endoscopy, esophageal manometry, and multichannel impedance pH monitoring. In patients with both symptom index and symptom association probability positive for weakly acidic reflux, each weakly acidic reflux was evaluated considering exact pH value, extension, physical characteristics, and correlation with heartburn. Forty-five patients with normal acid exposure time and positive symptom association probability for weakly acidic reflux were identified. The number of refluxes not heartburn related was higher than those heartburn related. In all distal and proximal liquid refluxes, as well as in distal mixed refluxes, the mean pH value of reflux events associated with heartburn was significantly lower than that not associated. This condition was not confirmed for proximal mixed refluxes. Overall, a low pH of weakly acidic reflux represents a determinant factor in provoking heartburn. This observation contributes to better understand the pathophysiology of symptoms generated by weakly acidic refluxes, paving the way toward the search for different therapeutic approaches to this peculiar condition of esophageal hypersensitivity.

    Gastroesophageal reflux disease (GERD) is a common disorder among elderly patients seeking medical care. Diagnosis and management of GERD in the older patient is a unique challenge for both the primary care provider and the gastroenterologist. Such patients may have atypical symptoms, more severe disease, and a higher rate of complications such as erosive esophagitis, Barrett esophagus, and esophageal cancer. Moreover, the elderly may be more sensitive to the morbidity and mortality of the available treatments for GERD. A careful and vigilant approach to the diagnosis, monitoring, and treatment of reflux disease in the elderly is warranted.

    Gastroesophageal reflux disease is a highly frequent disorder classically characterized by the presence of heartburn and/or acid regurgitation that improves with drug therapy that reduces acid content in the stomach. However, especially in patients with non-erosive disease, response to proton pump inhibitors is unsatisfactory in approximately 1 out of 3 patients, and consequently, in these patients, it is important to establish a definitive diagnosis and an alternative therapeutic strategy. In the last few years, advances have been made in knowledge of the physiopathology of reflux, such as identification of the role of the acid pocket in producing reflux, technological advances that allow differentiation among acid reflux, non-acid reflux and slightly acid reflux, and advances in the treatment of reflux with drugs that attempt to act on the barrier function of the esophagogastric junction.

    We investigated the 5-year clinical course in a cohort of patients with typical reflux symptoms and negative endoscopy. Prospective follow-up was conducted in patients with non-erosive reflux disease (NERD) for at least 5 years after initial evaluation with esophageal pH monitoring and upper gastrointestinal endoscopy. Within the last year of follow-up, reflux symptoms occurred in 27 of the 30 patients (90%). Twenty-five of twenty-seven symptomatic patients (93%) were on acid suppression therapy. The majority of our patients (70%) remained unchanged regarding their endoscopic status over 5 years. Progression to erosive esophagitis occurred in four patients with Los Angeles (LA) A (13%), three patients with LA B (10%), and two patients with LA C (7%). The presence of pathological acid exposure did not alter the presence of reflux symptoms over 5 years. Disease progression to erosive esophagitis occurred more frequently in patients with pathological acid exposure than those without pathological acid exposure (P= 0.025). Most NERD patients have symptoms and require acid suppression therapy 5 years after their initial diagnosis. Initial pathological acid exposure does not influence the use of acid suppression; however, it does influence the progression of NERD within 5 years of follow-up.

    Physiological gastroesophageal reflux (GER) is the passage of gastric contents into the esophagus and occurs up 2/3 of normal infants; and, it resolves spontaneously around 9-12 months of age. When GER causes symptoms or complications is considered gastroesophageal reflux disease (GERD) and it is associated to growth impairment, anemia, apnea, wheezing or other chronic respiratory symptoms, asthma, recurrent pneumonia or sleeping problems. Diagnosis of GERD implies studies as upper gastrointestinal series, upper endoscopy and 24 h esophageal pH monitoring; special cases may require motility and nuclear medicine studies. GER may be successfully treated with prone elevated position (30-45 degrees), shortening the feeding intervals to 3 h and anti-GER high-viscosity formulas. The regular use of prokinetic drugs is not recommended. The efficacy of proton pump inhibitors and H2 histamine receptor antagonists in the treatment of GERD has been demonstrated in children by diminishing de acid secretion of parietal cells, lowering the gastric contents and decreasing its ability to cause peptic-acid damage to the esophagus or to the respiratory tract. Surgical treatment is indicated in chronic recurrent GERD, usually in children 5 years or older with dependent proton pump inhibitor erosive esophagitis, chronic respiratory disease and in risk-selected cases.

    2008-01-01

    The pathophysiology of gastroesophageal reflux disease remains incompletely understood. Its hallmark symptom is "heartburn" and, on the basis of endoscopy, those with heartburn are subdivided into nonerosive reflux disease and erosive esophagitis. Although subjects with nonerosive reflux disease have no gross damage on endoscopy, a characteristic histopathologic feature of this disease is present on endoscopic biopsy. This lesion is known as "dilated intercellular spaces," a finding present within squamous epithelium. This report details how acid in contact with a damaged esophageal epithelium leads to heartburn and to the progression of nonerosive reflux disease to erosive esophagitis. It also addresses the fact that esophageal pH monitoring may be normal in a significant number of subjects with heartburn, particularly with nonerosive reflux disease, and details how this observation suggests that in addition to defects in the antireflux barrier, for example, transient lower esophageal sphincter relaxations and low lower esophageal sphincter pressure, defects in tissue resistance created by contact with ingested products may also be etiologic in some subjects with gastroesophageal reflux disease.

    2015-08-01

    Gastroesophageal reflux (GER) can cause respiratory symptoms and may trigger, drive and/or worsen airway disorders, interstitial lung diseases and lung allograft dysfunction. Whether lifestyle changes and acid suppression alone can counter and prevent the adverse effects of GER on the respiratory tract remains unclear. Recent data suggest that antireflux surgery may be more effective in preventing lung disease progression in patients with idiopathic pulmonary fibrosis or lung transplant recipients who have evidence of allograft dysfunction associated with the presence of excessive GER. Additional research and clinical trials are needed to determine the role of GER in various lung disorders and identify which interventions are most efficacious in preventing the respiratory consequences of gastroesophageal reflux disease. In addition, measuring biomarkers that indicate that gastric refluxate has been aspirated into the lower respiratory tract (e.g., pepsin and bile acid concentrations in bronchoalveolar lavage fluid) may prove helpful in both diagnosis and therapeutic decision making.

    Gastroesophageal reflux disease (GERD) encompasses an array of disorders unified by the reflux of gastric contents. Because there are many potential disease manifestations, esophageal and extraesophageal, there is no single biomarker of the entire disease spectrum; a set of GERD biomarkers that each quantifies specific aspects of GERD-related pathology might be needed. We review recent reports of biomarkers of GERD, specifically in relation to endoscopically negative esophageal disease and excluding conventional pH-impedance monitoring. We consider histopathologic biomarkers, baseline impedance, and serologic assays to determine that most markers are based on manifestations of impaired esophageal mucosal integrity, which is based on increased ionic and molecular permeability, and/or destruction of tight junctions. Impaired mucosal integrity quantified by baseline mucosal impedance, proteolytic fragments of junctional proteins, or histopathologic features has emerged as a promising GERD biomarker.

    Increased esophageal sensitivity and impaired mucosal integrity have both been described in patients with gastroesophageal reflux disease, but the relationship between hypersensitivity and mucosal integrity is unclear. The aim of the present study was to investigate acid sensitivity in patients with erosive and nonerosive reflux disease and control subjects to determine the relation with functional esophageal mucosal integrity changes as well as to investigate cellular mechanisms of impaired mucosal integrity in these patients. In this prospective experimental study, 12 patients with nonerosive reflux disease, 12 patients with esophagitis grade A or B, and 11 healthy control subjects underwent an acid perfusion test and upper endoscopy. Mucosal integrity was measured during endoscopy by electrical tissue impedance spectroscopy and biopsy specimens were analyzed in Ussing chambers for transepithelial electrical resistance, transepithelial permeability and gene expression of tight junction proteins and filaggrin. Patients with nonerosive reflux disease and esophagitis were more sensitive to acid perfusion compared with control subjects, having a shorter time to perception of heartburn and higher perceived intensity of heartburn. In reflux patients, enhanced acid sensitivity was associated with impairment of in vivo and vitro esophageal mucosal integrity. Mucosal integrity was significantly impaired in patients with esophagitis, displaying higher transepithelial permeability and lower extracellular impedance. Although no significant differences in the expression of tight junction proteins were found in biopsies among patient groups, mucosal integrity parameters in reflux patients correlated negatively with the expression of filaggrin. In conclusion, sensitivity to acid is enhanced in patients with gastroesophageal reflux disease, irrespective of the presence of erosions, and is associated with impaired esophageal mucosal integrity.

    Background: Epidemiologic and physiologic studies suggest an association between gastroesophageal reflux disease (GERD) and chronic cough. However, the benefit of antireflux therapy for chronic cough remains unclear, with most relevant trials reporting negative findings. This systematic review aimed to reevaluate the response of chronic cough to antireflux therapy in trials that allowed us to distinguish patients with or without objective evidence of GERD. Methods: PubMed and Embase systematic searches identified clinical trials reporting cough response to antireflux therapy. Datasets were derived from trials that used pH-metry to characterize patients with chronic cough. Results: Nine randomized controlled trials of varied design that treated patients with acid suppression were identified (eight used proton pump inhibitors [PPIs], one used ranitidine). Datasets from two crossover studies showed that PPIs significantly improved cough relative to placebo, albeit only in the arm receiving placebo first. Therapeutic gain in seven datasets was greater in patients with pathologic esophageal acid exposure (range, 12.5%-35.8%) than in those without (range, 0.0%-8.6%), with no overlap between groups. Conclusions: A therapeutic benefit for acid-suppressive therapy in patients with chronic cough cannot be dismissed. However, evidence suggests that rigorous patient selection is necessary to identify patient populations likely to be responsive, using physiologically timed cough events during reflux testing, minimal patient exclusion because of presumptive alternative diagnoses, and appropriate power to detect a modest therapeutic gain. Only then can we hope to resolve this vexing clinical management problem. PMID:23117307

  17. Refractory gastroesophageal reflux disease: advances and treatment.

    2014-08-01

    'Refractory gastroesophageal reflux disease' is one of the most common misnomers in the area of gastroesophageal reflux disease. The term implies reflux as the underlying etiology despite unresponsiveness to aggressive proton pump inhibitor therapy. The term should be replaced with 'refractory symptoms.' We must acknowledge that in many patients symptoms of reflux often overlap with non-GERD causes such as gastroparesis, dyspepsia, hypersensitive esophagus and functional disorders. Lack of response to aggressive acid suppressive therapy often leads to diagnostic testing. In majority of patients these tests are normal. The role of non-acid reflux in this group is uncertain and patients should not undergo surgical fundoplication based on this parameter. In patients unresponsive to acid suppressive therapy GERD is most commonly not causal and a search for non-GERD causes must ensue.

    Gastroesophageal reflux disease (GERD) is the most common acid-related disorder encountered during clinical practice in Pakistan and is associated with significant impairment of health-related quality of life. A number of guidelines and recommendations for the diagnosis and management of GERD have been published in different countries, but a Pakistani accepted directive by the standards of evidence-based medicine is still lacking. Our aim was to create an understanding of the natural history and presentations of reflux disease; evaluating possible treatment options available for the patients with complex and uncomplicated reflux ailments with the development of current and up to date evidence based endorsement, relevant to the needs of Pakistani health care providers in order to treat oesophageal manifestations of GERD. In order to make such guidelines, a comprehensive literature search was conducted with pertinent evidence reviewed, and quality of relevant data assessed. The resultant conclusions were based on the best available evidence and expert opinion of the authors of technical review panel.

    Abstract Background: This research aims to assess the response to acid suppression therapy in gastroesophageal reflux disease (GERD)-related chronic laryngitis (CL). Methods: Data were extracted from Web of Knowledge, Embase, and PubMed for English language article published up to March 2016. Pooled overall response rate (ORR) rates were evaluated to determine acid suppression treatment efficacy. Random effects model was used with standard approaches to sensitivity analysis, quality assessment, heterogeneity, and exploration of publication bias. Results: Pooled data from 21 reports (N = 2864, antireflux medicine: 2741; antireflux surgery: 123, study duration 4–108 week) were analyzed. With the random-effect model, the ORR was 66% (95% confidence interval [CI] 54%–78%). The ORRs were 80% for antireflux surgery (95% CI 67%–93%, 3 studies, 123 patients), whereas 64% for antireflux medicine (95% CI 50%–77%, 18 studies, 2741 patients), and the ORR was 70% (95% CI 55%–85%, 15 reports, 2731 patients) for >8 weeks’ therapy duration, whereas 57% (95% CI 48%–65%, 6 reports, 133 patients) for ≤8 weeks’ duration of therapy. Conclusions: Acid suppression seems to be an effective therapy for GERD-related CL. There was an increase in effect among patients with surgery therapeutic method and longer therapy duration.

    2008-01-01

    Reflux is a common cause of chronic cough. Surveys of patients with chronic cough point to a high association with gastroesophageal disease. Because of our bipedalism and speech, humans are prone to both reflux and aspiration. Whether the reflux of stomach contents into the esophagus alone is sufficient to cause cough or whether reflux into the upper airway is required is unknown. In 50 consecutive patients with chronic cough, symptoms of laryngopharangeal reflux (LPR) paralleled those of gastroesophageal reflux, suggesting no unique syndrome of LPR but that it is part of the protean manifestations of reflux disease.

    The aim of the present study was to investigate the efficacy of a potassium-competitive acid blocker (PCAB) named vonoprazan (VPZ) for improving symptoms in patients with reflux esophagitis (RE), non-erosive reflux disease (NERD), and functional dyspepsia (FD). A hospital-based, retrospective study of outpatients in our department (Department of Gastroenterology, University of Juntendo, Tokyo, Japan) between March 2015 and August 2016 was performed. The patients who were experiencing heartburn, acid regurgitation, gastric pain, and/or a heavy feeling in the stomach of at least moderate severity at baseline were treated with 20 mg VPZ once daily for 4 weeks. The patients completed the global overall symptom (GOS) scale to determine their symptom severity at baseline and after the 4 week treatment period. The proportions of patients with RE, NERD, and FD achieving improvement of their symptoms, defined as a GOS scale score of 1 (‘no problem’) or 2 (‘minimal problem’), were evaluated. During 4 weeks of VPZ therapy, changes in the gastroesophageal reflux disease (GERD) score, which was defined as the total points for heartburn and acid regurgitation on the GOS scale in patients with RE and NERD, and in the FD score, which was defined as the total points for gastric pain and a heavy feeling in the stomach on the GOS scale in patients with FD, were also evaluated. A total of 88 eligible cases were included in the present study, comprising 20 patients with RE, 25 patients with NERD, and 43 patients with FD. The rates of symptomatic improvement in patients with RE, NERD, and FD were 75.0, 60.0, and 48.8%, respectively. For the patients who were first administered VPZ, the rates of symptomatic improvement were 90.9, 66.7, and 58.8% in patients with RE, NERD, and FD, respectively. For those patients who were resistant to 8 weeks of proton pump inhibitor therapy, the rates of symptomatic improvement were 55.6, 53.8, and 42.3% in patients with RE, NERD, and FD

    Gastroesophageal reflux disease during pregnancy is common. Altered structure and function of the normal physiological barriers to reflux of gastric contents into the oesophagus explain the high incidence of this problem in pregnant women. For the majority of patients, life-style modifications are helpful, but are not sufficient to control symptoms and medication is required. The optimum management of reflux in pregnant patients requires special attention and expertise, since the safety of the mother, foetus and neonate remain the primary focus. Gastroenterologists and obstetricians should work together to optimise treatment. Typically, one utilises a step-up program that starts with life-style modifications and antacids. If those methods fail, histamine-2 receptor antagonists and proton pump inhibitors are tried. Rarely, promotility agents are used. Initiation of these medications must be undertaken after a careful discussion of risks and benefits with patients. In patients without a prior history of reflux, symptoms usually abate after delivery.

    Despite the frequency with which antireflux procedures are performed, decisions about gastroesophageal reflux disease treatment remain challenging. Several factors contribute to the difficulties in managing gastroesophageal reflux. First, the distinction between physiologic and pathologic gastroesophageal reflux (gastroesophageal reflux disease-GERD) is not always clear. Second, measures of the extent of gastroesophageal reflux often poorly correlate to symptoms or other complications attributed to reflux in infants and children. A third challenge is that the outcome of antireflux procedures, predominately fundoplications, are relatively poorly characterized. All of these factors contribute to difficulty in knowing when to recommend antireflux surgery. One of the manifestations of the uncertainties surrounding GERD is the high degree of variability in the utilization of pediatric antireflux procedures throughout the United States. Pediatric surgeons are frequently consulted for GERD and fundoplication, uncertainties notwithstanding. Although retrospective series and anecdotal observations support fundoplication in some patients, there are many important questions for which sufficient high-quality data to provide a clear answer is lacking. In spite of this, surgeons need to provide guidance to patients and families while awaiting the development of improved evidence to aid in these recommendations. The purpose of this article is to define what is known and what is uncertain, with an emphasis on the most recent evidence.

  5. Duodenogastric reflux in Chagas' disease

    1988-10-01

    Increased duodenogastric reflux has been recognized as a cause of gastric mucosa damage. The frequent finding of bile-stained gastric juice and a suggested higher frequency of lesions of the gastric mucosa in patients with Chagas' disease, which is characterized by a marked reduction of myenteric neurons, suggest that impairment of intrinsic innervation of the gut might be associated with increased duodenogastric reflux. Duodenogastric bile reflux was quantified after intravenous injection of 99mtechnetium-HIDA, in 18 patients with chronic Chagas' disease, 12 controls, and 7 patients with Billroth II gastrectomy. All but one of the chagasic patients were submitted to upper digestive tract endoscopy. High reflux values (greater than or equal to 10%) were detected both in chagasic patients and in the controls, but the values for both groups were significantly lower (P less than 0.01) than those obtained for Billroth II patients (median: 55.79%; range: 12.58-87.22%). Reflux values tended to be higher in the Chagas' disease group (median: 8.20%; range: 0.0-29.40%) than in the control group (median: 3.20%; range: 0.0-30.64%), with no statistical difference between the two groups (P greater than 0.10). Chronic gastritis was detected by endoscopy in 12 chagasic patients, benign gastric ulcer in 2 patients, and a pool of bile in the stomach in 11 patients. However, neither the occurrence of gastric lesions nor the finding of bile-stained gastric juice was associated with high reflux values after (99mTc)HIDA injection. This study suggests that lesions of the intramural nervous system of the gut in Chagas' disease do not appear to be associated with abnormally increased duodenogastric reflux.

    Gastroesophageal reflux disease is common in adult patients with interstitial lung disease. However, no data currently exist regarding the prevalence and characteristics of the disease in pediatric patients with interstitial lung disease. The aim of the present study was to prospectively assess the incidence of gastroesophageal reflux disease and characterize its features in children with interstitial lung disease. Gastroesophageal reflux disease was established based on 24 h pH-impedance monitoring (MII-pH). Gastroesophageal reflux episodes (GERs) were classified according to widely recognized criteria as acid, weakly acid, weakly alkaline, or proximal. Eighteen consecutive patients (15 boys, aged 0.2-11.6 years) were enrolled in the study. Gastroesophageal reflux disease was diagnosed in a half (9/18) of children. A thousand GERs were detected by MII-pH (median 53.5; IQR 39.0-75.5). Of these, 585 (58.5 %) episodes were acidic, 407 (40.7 %) were weakly acidic, and eight (0.8 %) were weakly alkaline. There were 637 (63.7 %) proximal GERs. The patients in whom gastroesophageal reflux disease was diagnosed had a significantly higher number of proximal and total GERs. We conclude that the prevalence of gastroesophageal reflux disease in children with interstitial lung disease is high; thus, the disease should be considered regardless of presenting clinical symptoms. A high frequency of non-acid and proximal GERs makes the MII-pH method a preferable choice for the detection of reflux episodes in this patient population.

    Gastroesophageal reflux disease (GERD) is defined by the presence of troublesome symptoms resulting from the reflux of gastric contents. The prevalence of GERD is increasing globally. An incompetent lower esophageal sphincter underlies the pathogenesis of GERD. Proton pump inhibitors (PPIs) form the core of GERD management. However, a substantial number of patients do not respond well to PPIs. The next option is anti-reflux surgery, which is efficacious, but it has its own limitations, such as gas bloating, inability to belch or vomit, and dysphagia. Laparoscopic placement of magnetic augmentation device is emerging as a useful alternative to conventional anti-reflux surgery. However, invasiveness of a surgical procedure remains a concern for the patients. The proportion of PPI non-responders or partial responders who do not wish for anti-reflux surgery defines the ‘treatment gap’ and needs to be addressed. The last decade has witnessed the fall and rise of many endoscopic devices for GERD. Major endoscopic strategies include radiofrequency ablation and endoscopic fundoplication devices. Current endoscopic devices score high on subjective improvement, but have been unimpressive in objective improvement like esophageal acid exposure. In this review, we discuss the current endoscopic anti-reflux therapies and available evidence for their role in the management of GERD. PMID:27744659

    Background/Aims Though nocturnal acid-breakthrough (NAB) is common in gastroesophageal reflux disease (GERD) patients, its clinical importance results from esophageal acidification, which has been shown to be uncommon. Ilaprazole, a long-acting proton pump inhibitor, may cause NAB infrequently. Accordingly, we studied prospectively, (1) frequency and degree of esophageal acidification during NAB, and (2) frequency and severity of NAB while on ilaprazole versus omeprazole. Methods Fifty-eight consecutive patients with GERD on once daily ilaprazole, 10 mg (n = 28) or omeprazole, 20 mg (n = 30) for > one month underwent 24-hour impedance-pH monitoring prospectively. NAB was defined as intra-gastric pH < 4 for > one hour during night, and esophageal acidification as pH < 4 for any duration. Nocturnal symptoms (heartburn, regurgitation, and chest pain) were also recorded. Results Of the 58 patients (age 35.5 [inter-quartile range 26.5–46.0] years, 38 [65.5%], 42 (72.4%) had NAB. Though patients with NAB had lower nocturnal intra-gastric pH than without (2.8 [1.9–4.1] vs 5.7 [4.6–6.8], P < 0.001), frequency and duration of nocturnal esophageal acidification (17/42 vs 4/16, P = 0.360 and 0.0 [0.0–1.0] vs 0.0 [0.0–0.3] minutes, P = 0.260, respectively) and symptoms were comparable (13/42 vs 6/16, P = 0.750). Though ilaprazole was associated with less NABs (1 [range 1–2, n = 19] vs 1 [range 1–3, n = 23], P = 0.010) than omeprazole, the frequency, duration, and mean intra-gastric pH during NAB were comparable (19/28 vs 23/30, P = 0.560; 117 [0–315] vs 159 [69–287] minutes, P = 0.500; 1.02 [0.7–1.4] vs 1.04 [0.44–1.3], P = 0.620, respectively). Conclusions Though NAB was common while patients were on a proton pump inhibitor, esophageal acidification was uncommon. Frequency and severity of NAB were comparable among patients on ilaprazole and omeprazole, except for the lesser number of NABs with ilaprazole. PMID:27585842

  9. Relationship between gastro-oesophageal reflux and airway diseases: the airway reflux paradigm.

    2011-04-01

    Our understanding of the relationship between gastro-oesophageal reflux and respiratory disease has recently undergone important changes. The previous paradigm of airway reflux as synonymous with the classic gastro-oesophageal reflux disease (GORD) causing heartburn has been overturned. Numerous epidemiological studies have shown a highly significant association of the acid, liquid, and gaseous reflux of GORD with conditions such as laryngeal diseases, chronic rhinosinusitis, treatment resistant asthma, COPD and even idiopathic pulmonary fibrosis. However, it has become clear from studies on cough hypersensitivity syndrome that much reflux of importance in the airways has been missed, since it is either non- or weakly acid and gaseous in composition. The evidence for such a relationship relies on the clinical history pointing to symptom associations with known precipitants of reflux. The tools for the diagnosis of extra-oesophageal reflux, in contrast to the oesophageal reflux of GORD, lack sensitivity and reproducibility. Unfortunately, methodology for detecting such reflux is only just becoming available and much additional work is required to properly delineate its role.

    There is a growing evidence that gastroesophageal reflux disease is related to several upper gastrointestinal cancers, mainly the esophageal adenocarcinoma and a certain type of gastric cardia adenocarcinoma. Currently, the incidence of gastroesophageal reflux disease is rapidly increasing in Korea. Therefore, there is a possibility of such increasing cancerous incidents, similar to the western worlds. In this article, the relationship between gastroesophageal reflux disease and several upper gastrointestinal cancers, the components of refluxate which has possible causal relationship with carcinogenesis, and the clinical implications of such relationship in the management of gastroesophageal reflux disease patients are discussed through the review of literature.

    2014-01-01

    Gastroesophageal reflux disease (GERD) is a common disease with a prevalence as high as 10%-20% in the western world. The disease can manifest in various symptoms which can be grouped into typical, atypical and extra-esophageal symptoms. Those with the highest specificity for GERD are acid regurgitation and heartburn. In the absence of alarm symptoms, these symptoms can allow one to make a presumptive diagnosis and initiate empiric therapy. In certain situations, further diagnostic testing is needed to confirm the diagnosis as well as to assess for complications or alternate causes for the symptoms. GERD complications include erosive esophagitis, peptic stricture, Barrett’s esophagus, esophageal adenocarcinoma and pulmonary disease. Management of GERD may involve lifestyle modification, medical therapy and surgical therapy. Lifestyle modifications including weight loss and/or head of bed elevation have been shown to improve esophageal pH and/or GERD symptoms. Medical therapy involves acid suppression which can be achieved with antacids, histamine-receptor antagonists or proton-pump inhibitors. Whereas most patients can be effectively managed with medical therapy, others may go on to require anti-reflux surgery after undergoing a proper pre-operative evaluation. The purpose of this review is to discuss the current approach to the diagnosis and treatment of gastroesophageal reflux disease. PMID:25133039

    Gastroesophageal reflux disease (GERD) is a common problem in children that is sometimes associated with dysphagia. Choking, food refusal, and food "getting stuck" are non-specific symptoms that may arise consequent to reflux and esophagitis. Swallowing plays a role in reflux physiology, functioning as a major clearance mechanism after reflux episodes. Therefore, failure of swallowing to effectively perform that function contributes to reflux pathophysiology. The diagnosis and treatment of GERD in children must be carried out systematically and thoroughly. Multiple interacting factors are common, thus complicating the process.

    Esophageal motility abnormalities are among the main factors implicated in the pathogenesis of gastroesophageal reflux disease. The recent introduction in clinical and research practice of novel esophageal testing has markedly improved our understanding of the mechanisms contributing to the development of gastroesophageal reflux disease, allowing a better management of patients with this disorder. In this context, the present article intends to provide an overview of the current literature about esophageal motility dysfunctions in patients with gastroesophageal reflux disease. Esophageal manometry, by recording intraluminal pressure, represents the gold standard to diagnose esophageal motility abnormalities. In particular, using novel techniques, such as high resolution manometry with or without concurrent intraluminal impedance monitoring, transient lower esophageal sphincter (LES) relaxations, hypotensive LES, ineffective esophageal peristalsis and bolus transit abnormalities have been better defined and strongly implicated in gastroesophageal reflux disease development. Overall, recent findings suggest that esophageal motility abnormalities are increasingly prevalent with increasing severity of reflux disease, from non-erosive reflux disease to erosive reflux disease and Barrett's esophagus. Characterizing esophageal dysmotility among different subgroups of patients with reflux disease may represent a fundamental approach to properly diagnose these patients and, thus, to set up the best therapeutic management. Currently, surgery represents the only reliable way to restore the esophagogastric junction integrity and to reduce transient LES relaxations that are considered to be the predominant mechanism by which gastric contents can enter the esophagus. On that ground, more in depth future studies assessing the pathogenetic role of dysmotility in patients with reflux disease are warranted.

    The prevalence of gastroesophageal reflux disease (GERD) in South Korea has increased over the past 10 years. Patients with erosive reflux disease (ERD) shows better response to proton pump inhibitors (PPIs) than those with non-erosive reflux disease (NERD). NERD is a heterogeneous condition, showing pathological gastroesophageal reflux or esophageal hypersensitivity to reflux contents. NERD patients with pathological gastroesophageal reflux or hypersensitivity to acid may respond to PPIs. However, many patients with esophageal hypersensitivity to nonacid or functional heartburn do not respond to PPIs. Therefore, careful history and investigations are required when managing patients with refractory GERD who show poor response to conventional dose PPIs. Combined pH-impedance studies and a PPI diagnostic trial are recommended to reveal underlying mechanisms of refractory symptoms. For those with ongoing reflux-related symptoms, split dose administration, change to long-acting PPIs or PPIs less influenced by CYP2C19 genotypes, increasing dose of PPIs, and the addition of alginate preparations, prokinetics, selective serotonin reuptake inhibitors, or tricyclic antidepressants can be considered. Pain modulators, selective serotonin reuptake inhibitors, or tricyclic antidepressants are more likely to be effective for those with reflux-unrelated symptoms. Surgery or endoscopic per oral fundoplication may be effective in selected patients.

    The present definition of gastroesophageal reflux disease is based on clinical criteria that are difficult to reproduce accurately. Pathologists are supposed to confirm the presence of morphological changes induced by gastroesophageal reflux. Traditional evaluation of injury, inflammatory and reactive changes of esophageal squamous epithelium lacks both sufficient sensitivity and specificity, and thus the modern diagnostic focuses on chronic metaplastic changes of esophageal mucosa defined as any mucosal type proximal to the upper border of oxyntic mucosa (also called fundic mucosa of the stomach). In the setting of gastroesophageal reflux the esophageal mucosa, under normal conditions lined with squamous epithelium, undergoes columnar metaplasia. According to morphology and immunophenotype of columnar cells, the columnar metaplasia may be further subdivided to oxyntocardiac mucosa, cardiac mucosa, intestinal metaplasia, and an intermediate type of cardiac mucosa expressing intestinal transcription factor CDX2, but devoid of goblet cells. The latter two mucosal types are currently thought to represent the most probable candidates for neoplastic transformation, whereas oxyntocardiac mucosa is believed to represent a stable compensatory change with no risk of further progression. An evaluation of dysplastic changes (intraepithelial neoplasia) in the setting of columnar lined esophagus necessitates correlation with the second opinion of a GI expert to prevent potentially harmful under- or over-treatment of the patient. Regarding invasive adenocarcinoma, the pathologist should avoid overdiagnosis of the infiltration of the space between the two layers of columnar lined esophagus - associated split muscularis mucosae as invasion of submucosa, as it is associated with different prognosis. Critical evaluation of the real impact of acid suppression on neoplastic transformation in the setting of gastroesophageal reflux disease may represent the greatest challenge for future

    Gastroesophageal reflux disease (GERD), a common disorder with troublesome symptoms caused by reflux of gastric contents into the esophagus, has adverse impact on quality of life. A variety of medications have been used in GERD treatment, and acid suppression therapy is the mainstay of treatment for GERD. Although proton pump inhibitor is the most potent acid suppressant and provides good efficacy in esophagitis healing and symptom relief, about one-third of patients with GERD still have persistent symptoms with poor response to standard dose PPI. Antacids, alginate, histamine type-2 receptor antagonists, and prokinetic agents are usually used as add-on therapy to PPI in clinical practice. Development of novel therapeutic agents has focused on the underlying mechanisms of GERD, such as transient lower esophageal sphincter relaxation, motility disorder, mucosal protection, and esophageal hypersensitivity. Newer formulations of PPI with faster and longer duration of action and potassium-competitive acid blocker, a newer acid suppressant, have also been investigated in clinical trials. In this review, we summarize the current and developing therapeutic agents for GERD treatment. PMID:23878534

    Gastroesophageal reflux refers to the passage of gastric contents including food, acid, and digestive enzymes up into the esophagus. Reflux is most commonly recognized in infants when it is associated with regurgitation, known as “spitting up,” and it is usually a self-limited, benign process that has little or no effect on normal weight gain or development. Adults and adolescents may also have reflux, which is usually either asymptomatic or recognized as dyspepsia or “heartburn.” Gastroesophageal reflux disease (GERD) is defined as symptoms or complications that result from reflux. Most evidence suggests the mechanism of reflux is due to transient relaxations of the lower esophageal sphincter at inappropriate times. The diagnosis of suspected GERD in infants and children depends on the age and the presenting symptoms. A thorough history, physical examination, and growth charts are sufficient for the evaluation and diagnosis of GERD in most infants with recurrent vomiting or children with regurgitation and heartburn. Additional evaluation may include an upper gastrointestinal series, esophageal pH monitoring, or endoscopy. The goals of GERD management are eliminating symptoms, healing esophagitis, preventing complications, promoting normal weight gain and growth, and maintaining remission. Therapeutic options include lifestyle changes, pharmacologic therapy, and anti-reflux surgery. Currently available pharmacologic agents for the treatment of GERD include antacids, mucosal protectants, prokinetic agents, and acid suppressants. PMID:23118703

    Proton pump inhibitor (PPI) is major treatment for acid reflux. It reduces major symptom of GERD and effective. However, the cause of GERD is the insufficiency of anti-reflux mechanism of cardia. Only surgical treatment can care for hiatal hernia as the main cause of the disruption. Redundant reflux against conservative treatment or obvious hiatal hernia is indication for laparoscopic Nissen fundoplication. Late diagnosis might request radical operation, so we need to know the indication for laparoscopic treatment. For the safer laparoscopic procedure, we perform curtain retraction technique and Floppy Nissen -short cuff method. The former contribute to prevent hemorrhage or pneumothorax, and the latter can reduce the post-operative disphagia.

    Gastroesophageal reflux disease can have variable manifestations including regurgitation, irritability, arching, choking, and apnea. The disorder is also frequently mistaken for seizures (Sandifer syndrome). We report 6 patients in whom the opposite phenomenon occurred: their seizures were mistaken for gastroesophageal reflux disease. Six of 77 patients (6.8%) with gelastic seizures and epilepsy symptomatic of hypothalamic hamartomas were noted to be misdiagnosed with gastroesophageal reflux disease in infancy. As is typical in these patients, gelastic seizures were not diagnosed until months, or often years, later. Delayed diagnosis of hypothalamic hamartomas can lead to a potentially deleterious syndrome involving refractory epilepsy, developmental problems, and precocious puberty. Gelastic seizures should be considered among the conditions that can mimic reflux symptoms.

    Objective. To investigate effects and possible mechanisms of transcutaneous electrical acustimulation (TEA) performed by a wearable watch-size stimulator for refractory gastroesophageal reflux disease (RGERD). Methods. Twenty patients diagnosed as RGERD were enrolled in the study and randomly divided into four groups: esomeprazole group (Group A), esomeprazole combined with TEA group (Group B), esomeprazole combined with sham-TEA group (Group C), and esomeprazole combined with domperidone group (Group D). HRM and 24 h pH-impedance monitoring and GerdQ score were used to measure related indexes before and after treatment. Results. (1) TEA significantly increased LESP, compared with PPI treatment only or PPI plus sham-TEA. After pairwise comparison, LESP of Group B was increased more than Group A (P = 0.008) or Group C (P = 0.021). (2) PPI plus TEA decreased not only the number of acid reflux episodes but also the number of weak acid reflux episodes (P = 0.005). (3) Heartburn and reflux symptoms were improved more with PPI + TEA than with PPI treatment only or PPI plus sham-TEA (GerdQ scores, P = 0.001). Conclusion. TEA can improve symptoms in RGERD patients by increasing LESP and decreasing events of weak acid reflux and acid reflux; addition of TEA to esomeprazole significantly enhances the effect of TEA.

Upper gastrointestinal endoscopy and pH monitoring are poorly sensitive for diagnosing reflux in this group of patients. Instead it is recommended that in those without warning symptoms, an empiric trial of proton-pump inhibitors be the initial approach to diagnosing and treating the potential underlying cause of these extraesophageal symptoms.

    Background The insula plays a significant role in the interoceptive processing of visceral stimuli. We have previously shown that GERD patients have increased insular cortex activity during esophageal stimulation, suggesting a sensitized esophago-cortical neuraxis. However, information regarding the functional connectivity (FC) of the insula during visceral stimulation is lacking. The primary aim of this study was to investigate the FC of insular subregions during esophageal acid stimulation. Methods Functional imaging data was obtained from 12 GERD patients and 14 healthy subjects during four steady state conditions: (1) presence of transnasal esophageal catheter (pre-infusion); (2) neutral solution; (3) acid infusion; (4) presence of transnasal esophageal catheter following infusions (post-infusion). The insula was parcellated into 6 regions of interest (ROI). FC maps between each insular ROI and interoceptive regions were created. Differences in FC between GERD patients and healthy subjects were determined across the 4 study conditions. Key Results All GERD patients experienced heartburn during and after esophageal acidification. Significant differences between GERD patients and healthy subjects were seen in: (1) insula-thalamic FC (neutral solution infusion, acid infusion, post-infusion); (2) insula-amygdala FC (acid infusion, post-infusion); (3) insula-hippocampus and insula-cingulate FC (post-infusion). Conclusions & Inferences Esophageal stimulation in GERD patients revealed significant insular cortex FC differences with regions involved in viscerosensation and interoception. The results of our study provide further evidence that the insula, located at the transition of afferent physiologic information to human feelings, is essential for both visceral homeostasis and the experience of heartburn in GERD patients.

    Although gastroesophageal reflux disease (GERD) is a common disorder in Western countries, with a significant impact on quality of life and healthcare costs, the mechanisms involved in the pathogenesis of symptoms remain to be fully elucidated. GERD symptoms and complications may result from a multifactorial mechanism, in which acid and acid-pepsin are the important noxious factors involved. Prolonged contact of the esophageal mucosa with the refluxed content, probably caused by a defective anti-reflux barrier and luminal clearance mechanisms, would appear to be responsible for macroscopically detectable injury to the esophageal squamous epithelium. Receptors on acid-sensitive nerve endings may play a role in nociception and esophageal sensitivity, as suggested in animal models of chronic acid exposure. Meanwhile, specific cytokine and chemokine profiles would appear to underlie the various esophageal phenotypes of GERD, explaining, in part, the genesis of esophagitis in a subset of patients. Despite these findings, which show a significant production of inflammatory mediators and neurotransmitters in the pathogenesis of GERD, the relationship between the hypersensitivity and esophageal inflammation is not clear. Moreover, the large majority of GERD patients (up to 70%) do not develop esophageal erosions, a variant of the condition called non-erosive reflux disease. This summary aims to explore the inflammatory pathway involved in GERD pathogenesis, to better understand the possible distinction between erosive and non-erosive reflux disease patients and to provide new therapeutic approaches.

    OBJECTIVE: To assess the knowledge and practice of pediatricians about infants with physiological reflux and gastroesophageal reflux disease. METHODS: 140 pediatricians were interviewed during two scientific events in 2009 and 2010. The questions referred to two clinical cases of infants. One with symptoms of infant regurgitation (physiological reflux) and another with gastroesophageal reflux disease. RESULTS: Among 140 pediatricians, 11.4% (n=16) and 62.1% (n=87) would require investigation tests, respectively for infant regurgitation (physiological reflux) and gastroesophageal reflux disease. A series of upper gastrointestinal exams would be the first requested with a higher frequency. Medication would be prescribed by 18.6% (n=6) in the case of physiological reflux and 87.1% (n=122) in the case of gastroesophageal reflux disease. Prokinetic drugs would be prescribed more frequently than gastric acid secretion inhibitors. Sleeping position would be recommended by 94.2% (n=132) and 92.9% (n=130) of the respondents, respectively for the case of physiological reflux and gastroesophageal reflux disease; however, about half of the respondents would recommend the prone position. Only 10 (7.1%) of the pediatricians would exclude the cow's milk protein from the infants' diet. CONCLUSIONS: Approaches different from the international guidelines are often considered appropriate, especially when recommending a different position other than the supine and prescription of medication. In turn, the interviews enable us to infer the right capacity of the pediatricians to distinguish physiologic reflux and gastroesophageal reflux disease correctly. PMID:25662014

    Though efficient acid suppression with proton pump inhibitors (PPIs) remains the mainstay of treatment of gastroesophageal reflux disease (GERD), some of the patients showed refractory response to PPIs, necessitating further intervention. After increasing dose of PPIs and other kinds of pharmacological intervention adopting prokinetics or others, variable endoscopic treatments are introduced for the treatment of these refractory cases. The detailed introduction regarding endoscopic treatment for GERD is forwarded in this review article. Implantation of reabsorbable or synthetic materials in the distal esophagus was tried in vain and is expelled from the market due to limited efficacy and serious complication.

    Gastroesophageal reflux disease (GERD) is one of the most common problems treated by primary care physicians. Almost 20% of the population in the United States experiences occasional regurgitation, heartburn, or retrosternal pain because of GERD. Reflux disease is complex, and the physiology and pathogenesis are still incompletely understood. However, abnormalities of any one or a combination of the three physiologic processes, namely, esophageal motility, lower esophageal sphincter function, and gastric motility or emptying, can lead to GERD. There are many diagnostic and therapeutic approaches to GERD today, but more studies are needed to better understand this complex disease process.

    The objective of this study was to formulate and evaluate the lansoprazole (LPZ)-loaded microparticles to prevent nocturnal acid breakthrough in the case of gastro-esophageal reflux disease (GERD). The microparticulate delivery system was prepared by solvent evaporation method using Eudragit RS100 as a matrix polymer followed by enteric coated with Eudragit S100 and hydroxypropyl methylcellulose phthalate HP55 using spray drying method. The enteric coated microparticles were stable in gastric pH condition. In vivo pharmacokinetic and pharmacodynamic studies in male Wistar rats demonstrated that enteric coated microparticles sustained release of LPZ and promoted ulcer healing activity. In other words, the microparticulate dosage form provided effective drug concentration for a longer period as compared to conventional extended release dosage form, and showed sufficient anti-acid secretion activity to treat acid related disorders including the enrichment of nocturnal acid breakthrough event based on a once daily administration.

    Previously published studies have indicated that gastroesophageal reflux (GER) disease is common in pediatric patients with cystic fibrosis. The aim of the present study was to get insight into the incidence of GER and to characterize the nature of reflux episodes in children with cystic fibrosis. This was a multicenter, prospective study of children with cystic fibrosis older than 18 months. Forty four consecutive patients (22 boys, mean age 10.4 ± 3.6, range 3.0-17.8 years) were enrolled into the study. All patients underwent 24 h pH-impedance monitoring. GER were classified according to the widely recognized criteria as an acid, weakly acid, weakly alkaline, or proximal. The pH-impedance trace was considered abnormal when acid exposure was >6 %. GER was diagnosed in 24/44 (54.5 %) children. A total of 1585 (median 35, range 7-128) reflux episodes were detected; 1199 (75.6 %) were acidic, 382 (24.1 %) weakly acidic, and 4 (0.3 %) weakly alkaline. Six hundred and ninety-one (43.6 %) reflux episodes reached the proximal esophagus. In 14/44 patients typical GER symptoms were present. We conclude that the incidence of GER in children with cystic fibrosis is very high. In the majority of patients typical GER symptoms are absent. Therefore, diagnostic procedures should be considered, regardless of lacking symptoms. Although acid reflux episodes predominate in children with cystic fibrosis, classical pH-metry may not constitute a sufficient diagnostic method in this population because of a relatively high number of proximal reflux episodes. Such episodes also indicate an increased risk for aspiration. The pH-impedance diagnostic measurement is advocated when suspecting GER in children with cystic fibrosis.

    Gastroesophageal reflux disease (GERD) is widely associated with asthma, chronic cough, and laryngitis. Many studies have focused on acidic reflux; however, acid is just one of many factors that can cause pulmonary injury. The discrepancy between the high frequency of GERD in asthmatic patients and the ineffective reflux therapy outcomes in these patients suggests that GERD may cause injury through other mechanisms, such as pepsinogen, pepsin, bile salts, or other components of reflux materials, instead of the acid. Research using appropriate and innovative methodologies to investigate these potential inflammatory agents in patients with GERD is required to determine the underlying factors associated with pulmonary disorders in these patients.

    Gastroesophageal reflux disease (GERD) is a condition that develops when the reflux of gastric contents into the esophagus leads to troublesome symptoms and/or complications. Heartburn is the cardinal symptom, often associated with regurgitation. In patients with endoscopy-negative heartburn refractory to proton pump inhibitor (PPI) therapy and when the diagnosis of GERD is in question, direct reflux testing by impedance-pH monitoring is warranted. Laparoscopic fundoplication is the standard surgical treatment for GERD. It is highly effective in curing GERD with a 80% success rate at 20-year follow-up. The Nissen fundoplication, consisting of a total (360°) wrap, is the most commonly performed antireflux operation. To reduce postoperative dysphagia and gas bloating, partial fundoplications are also used, including the posterior (Toupet) fundoplication, and the anterior (Dor) fundoplication. Currently, there is consensus to advise laparoscopic fundoplication in PPI-responsive GERD only for those patients who develop untoward side-effects or complications from PPI therapy. PPI resistance is the real challenge in GERD. There is consensus that carefully selected GERD patients refractory to PPI therapy are eligible for laparoscopic fundoplication, provided that objective evidence of reflux as the cause of ongoing symptoms has been obtained. For this purpose, impedance-pH monitoring is regarded as the diagnostic gold standard.

    Gastroesophageal reflux (GER) is commonly associated with respiratory symptoms, either through a vagal bronchoconstrictive reflex or through microaspiration of gastric contents. No diagnostic test is available, however, to diagnose when respiratory illnesses are caused by GER and when not, but research in this field has been moving forward. Various biomarkers in different types of biosamples have been studied in this context. The aim of this review is to summarize the present knowledge in this field. GER patients with respiratory diseases seem to have a different biochemical profile from similar patients without GER. Inflammatory biomarkers differ in asthmatics based on GER status, tachykinins are elevated in patients with GER-related cough, and bile acids are elevated in lung transplant patients with GER. However, studies on these biomarkers are often limited by their small size, methods of analysis, and case selections. The two pathogenesis mechanisms are associated with different respiratory illnesses and biochemical profiles. A reliable test to identify GER-induced respiratory disorders needs to be developed. Bronchoalveolar lavage is too invasive to be of use in most patients. Exhaled breath condensate samples need further evaluation and standardization. The newly developed particles in exhaled air measurements remain to be studied further. PMID:23653634

  14. Associations between peripheral vertigo and gastroesophageal reflux disease.

    We hypothesize that peripheral vertigo is associated with gastroesophageal reflux disease (GERD). Two mechanisms could be considered – gastric acids may directly irritate the respiratory mucosa and cause inflammation, or Helicobacter pylori (H. pylori) could be present and cause local infection. Reflux material (Hydrochloric acid (HCl) and pepsin) could get into the middle ear via Eustachian tube and affect osseous structures directly. Disturbance of ossicles could cause tinnitus, which is more common for peripheral vertigo. H. pylori could also get in the esophagus and in the upper respiratory tract via gastroesophageal reflux, and could cause tympanosclerosis and fixation of ossicles. In our study group, 120 of 153 (78.4%) patients had gastroesophageal reflux disease (GERD). Diagnostic tests of H. pylori (rapid urease test or blood antibody test) were performed for 96 of 120 (80%) patients with GERD and were found positive for 32 of 96 (33.3%) patients. Peripheral vertigo was present in 93 of 120 (77.6%) patients with GERD compared to 33 of 126 (26%) patients without GERD (χ(2)=9.016, p=0.003). H. pylori and peripheral vertigo coexisted in 26 of 126 patients (20.6%) (OR 1.36; 95% CI 0.49-3.74, p=0.55). Our study demonstrated statistically significant association between peripheral vertigo and GERD but not between peripheral vertigo and H. pylori. Further more extensive investigations are needed in order to explore our hypothesis.

    Gastroesophageal reflux disease (GERD) and/or hiatus hernia (HH) are one of the most common disorders of the upper gastrointestinal tract. Despite the positive effect of sleeve gastrectomy (SG) regarding weight loss and improvement in obesity co-morbidities, there are concerns about the development of de novo gastroesophageal reflux disease or worsening the existing GERD after this bariatric operation. Furthermore, controversy exists on the consequences of SG in lower esophageal sphincter function and about the ideal procedure when a hiatus hernia is preoperatively diagnosed or discovered during the laparoscopic SG. This review systematically investigates the incidence, the pathophysiology of GERD and/or HH in morbidly obese individuals before and after SG, and the treatment options for concomitant HH repair during laparoscopic sleeve gastrectomy.

    BACKGROUND—Helicobacter pylori infection is less prevalent and atrophic gastritis is less extensive in patients with reflux oesophagitis than those without it, but few studies have examined this relationship directly.
AIMS—We investigated the relationship between H pylori infection, acid secretion, and reflux oesophagitis in Japanese subjects.
SUBJECTS—A total of 105 patients with erosive reflux oesophagitis were compared with 105 sex and age matched patients without reflux oesophagitis.
METHODS—The diagnosis of H pylori infection was made by histological examination of gastric mucosal biopsy specimens, rapid urease test, and detection of serum IgG antibodies. Acid secretion was assessed by the endoscopic gastrin test.
RESULTS—H pylori infection was present in 36 patients with erosive reflux oesophagitis (34.3%) and in 80 control subjects (76.2%) (odds ratio 0.163, 95% confidence interval 0.09-0.29). Overall acid secretion was significantly greater in patients with reflux oesophagitis. Among H pylori positive patients, acid secretion was greater in patients with reflux oesophagitis than those without oesophagitis.
CONCLUSION—In Japan, erosive reflux oesophagitis occurs most often in the absence of H pylori infection and gastric hyposecretion. Even in the presence of H pylori infection, reflux oesophagitis is more likely to develop in patients without gastric hyposecretion. H pylori infection may inhibit reflux oesophagitis by inducing hypoacidity.

    Background/Aims Gastroesophageal reflux disease (GERD) is diagnosed based on symptoms of heartburn and regurgitation but is a heterogeneous condition which can be subclassified according to endoscopy and esophageal reflux monitoring. The aim of this study was to identify differences in demographic characteristics and reflux symptom patterns among patients with various spectrum of GERD. Methods Patients having weekly heartburn or acid regurgitation were classified into four pathophysiological subgroups according to endoscopy and pH monitoring: reflux esophagitis (RE), endoscopy-negative reflux disease with pathological reflux (PR+), hypersensitive esophagus (HE), and normal acid exposure with negative symptom association (pH-). Results A total of 195 patients were enrolled. The numbers of patients in the subgroups were: RE, 39.0%; PR+, 20.0%; HE, 10.3%; and pH-, 30.8%. Grossly, reflux symptom patterns and relieving/exacerbating factors did not differ between subgroups. Prevalence of extraesophageal syndrome was higher in patients with PR+ than in other groups. Overlapping functional dyspepsia was common in all groups. The SCL-90-R depression score was higher in PR+ patients than in RE patients (p<0.05). Conclusions Demographic characteristics and reflux symptom patterns cannot differentiate pH- group from GERD subtypes. Esophageal pH monitoring could be considered for the initial evaluation of GERD in the tertiary referral setting. PMID:24672658

    The prevalence of gastroesophageal reflux disease (GERD) has mirrored the increase in obesity, and GERD is now recognized as an obesity-related comorbidity. There is growing evidence that obesity, specifically central obesity, is associated with the complications of chronic reflux, including erosive esophagitis, Barrett's esophagus, and esophageal adenocarcinoma. While fundoplication is effective in creating a competent gastroesophageal junction and controlling reflux in most patients, it is less effective in morbidly obese patients. In these patients a bariatric operation has the ability to correct both the obesity and the abnormal reflux. The Roux-en-Y gastric bypass is the preferred procedure.

    The objective of this study is to evaluate the incidence of pathologic gastroesophageal reflux in laryngectomized patient with phonatory prosthesis, analyzing potential related problems and appraising, at the same time, the effectiveness of a therapeutic protocol. A retrospective study was conducted on 43 phonatory prosthesis patients who had problems with regard to recurrent tracheoesophageal granulations, the need of frequent prosthesis replacement, within a 3-month period, and unsatisfactory vocal results. Such patients underwent physical examination of the fistula region and of the neopharynx and were submitted to esophagogastroduodenoscopy. Moreover the group of patients underwent a therapeutic protocol and were re-evaluated posttreatment, examining fistula region both on the tracheal side and on the esophageal side through videolaryngostroboscopy. Of the 43 recruited patients 13 (30%) presented tracheoesophageal granulations, 20 (46.5%) unsatisfactory vocal results and 10 (23.5%) frequent prosthesis replacement, within a 3-month period, due to abnormal biofilm development. In particular, of the 13 patients who had recurrent granulations, the evaluation results revealed the presence of gastroesophageal reflux disease (GERD) in 6 cases (46%). In the group of patients presenting unsatisfactory vocal results GERD was shown in 13 cases (65%). In the third group of patients GERD was found in two cases (20%). The overall analysis of the data gathered, allowed to identify GERD in 21 (49%) of the 43 patients submitted to the study. The results posttreatment indicated, in the first group, the disappearance or a significant (>75%) volume reduction of such formation in five cases (38%, p = 0.002). In the second group an overall improvement in the quality of voice was displayed at least for 12 patients (60%, p = 0.0001). Finally in the last group an increase of the prosthesis life was recorded in four (40%, p = 0.05) of the ten patients who had the need of prosthesis

    Gastroesophageal reflux disease (GERD) is diagnosed based on typical symptoms in clinical practice. It can be divided into two groups using endoscopy: erosive and nonerosive reflux disease (NERD). This study aims to determine the risk factors of reflux symptoms and mucosal injury. This was a two-step case-control study derived from a cohort of 998 individuals having the data of reflux disease questionnaire (RDQ) and endoscopic findings. Those with minor reflux symptoms were excluded. The first step compared symptomatic GERD patients with healthy controls. The 2(nd) step compared patients with erosive esophagitis with healthy controls. In this study, the prevalence of symptomatic GERD and erosive esophagitis were 163 (16.3%) and 166 (16.6%), respectively. A total of 507 asymptomatic individuals without mucosal injury of the esophagus on endoscopy were selected as healthy controls. Compared with healthy controls, multivariate analyses showed that symptomatic GERD patients had a higher prevalence of hypertriglyceridemia [odds ratio (OR), 1.83; 95% confidence interval (CI) 1.13-2.96] and obesity (OR, 1.85; 95% CI 1.08-3.02). By contrast, male sex (OR, 2.24; 95% CI 1.42-3.52), positive Campylo-like organism (CLO) test (OR, 0.56; 95% CI 0.37-0.84), and hiatus hernia (OR, 14.36; 95% CI 3.05-67.6) were associated with erosive esophagitis. In conclusion, obesity and hypertriglyceridemia were associated with reflux symptoms. By contrast, male sex, negative infection of Helicobacter pylori, and hiatus hernia were associated with mucosal injury. Our results suggested that risk factors of reflux symptoms or mucosal injury might be different in GERD patients. The underlying mechanism awaits further studies to clarify.

    Gastroesophageal reflux disease (GERD) affects both men and women worldwide, with the most common symptom of GERD being frequent heartburn. If left untreated, more serious diseases including esophagitis and/or esophageal cancer may result. GERD has been commonly held to be the result of gastric acid refluxing into the esophagus. Recent work, however, has shown that there are acid-producing cells in the upper aerodigestive tract. In addition, acid-producing bacteria located within the upper gastrointestinal tract and oral cavity may also be a contributing factor in the onset of GERD. Proton pump inhibitors (PPIs) are commonly prescribed for treating GERD; these drugs are designed to stop the production of gastric acid by shutting down the H(+)/K(+)-ATPase enzyme located in parietal cells. PPI treatment is systemic and therefore significantly different than traditional antacids. Although a popular treatment choice, PPIs exhibit substantial interpatient variability and commonly fail to provide a complete cure to the disease. Recent studies have shown that H(+)/K(+)-ATPases are expressed in tissues outside the stomach, and the effects of PPIs in these nongastric tissues have not been fully explored. Likewise, acid-producing bacteria containing proton pumps are present in both the oral cavity and esophagus, and PPI use may also adversely affect these bacteria. The use of PPI therapy is further complicated by the two philosophical approaches to treating this disease: to treat only symptoms or to treat continuously. The latter approach frequently results in unwanted side effects which may be due to the PPIs acting on nongastric tissues or the microbes which colonize the upper aerodigestive tract.

    Introduction Gastroesophageal reflux disease (GERD) is probably one of the most prevalent diseases in the world that also compromises the quality of life of the affected significantly. Its incidence in Brazil is 12%, corresponding to 20 million individuals. Objective To update the GERD management and the new trends on diagnosis and treatment, reviewing the international and Brazilian experience on it. Method The literature review was based on papers published on Medline/Pubmed, SciELO, Lilacs, Embase and Cochrane crossing the following headings: gastroesophageal reflux disease, diagnosis, clinical treatment, surgery, fundoplication. Results Various factors are involved on GERD physiopathology, the most important being the transient lower esophageal sphincter relaxation. Clinical manifestations are heartburn, regurgitation (typical symptoms), cough, chest pain, asthma, hoarseness and throat clearing (atypical symptoms), which may be followed or not by typical symptoms. GERD patients may present complications such as peptic stenosis, hemorrhage, and Barrett's esophagus, which is the most important predisposing factor to adenocarcinoma. The GERD diagnosis must be based on the anamnesis and the symptoms must be evaluated in terms of duration, intensity, frequency, triggering and relief factors, pattern of evolution and impact on the patient's quality of life. The diagnosis requires confirmation with different exams. The goal of the clinical treatment is to relieve the symptoms and surgical treatment is indicated for patients who require continued drug use, with intolerance to prolonged clinical treatment and with GERD complications. Conclusion GERD is a major digestive health problem and affect 12% of Brazilian people. The anamnesis is fundamental for the diagnosis of GERD, with special analysis of the typical and atypical symptoms (duration, intensity, frequency, triggering and relief factors, evolution and impact on the life quality).

    Patients with Barrett's esophagus have been reported to have impaired visceral sensitivity to acid perfusion and distension compared with non-Barrett's refluxers, but the mechanism is poorly understood. Esophageal motility and clearance mechanisms may be important, and this study explored the relationship of motility with symptoms. Seventy-four patients with Barrett's esophagus were compared with 216 patients with gastro-esophageal reflux disease (GERD) with abnormal acid reflux scores, and 50 symptomatic patients who had normal acid exposure. All patients had esophageal manometry and 24-h pH monitoring. Thirty-six Barrett's patients also had 24-h bile reflux monitoring. Symptoms were assessed by Symptom Index (SI) during 24-h pH monitoring. Barrett's patients with normal motility had a significantly lower SI than GERD patients for similar acid exposure (P < 0.001). Barrett's patients with abnormal motility had higher acid exposure than those with normal motility (P < 0.05), but the SI values for this group was not significantly different from the GERD patients. SI and Bile reflux in Barrett's esophagus was not significantly different in patients with normal or abnormal motility. Barrett's patients had less sensitivity than GERD patients for similar acid exposure. Normal motility in Barrett's esophagus is associated with the poorest sensitivity and the presence of increased acid exposure is required in order to achieve sensitivity levels comparable with GERD patients.

    Background/Aims Anti-reflux barrier dysfunction is one of the primary mechanisms in gastroesophageal reflux disease (GERD) pathogenesis. The esophagogastric junction contractile integral (EGJ-CI) is a new metric adopted to evaluate the EGJ contractility, which implies the anti-reflux barrier function. The aim of the current study was to validate this new metric in patients with GERD and its correlation with the esophageal acid exposure, as well as the efficacy of proton pump inhibitor treatment. Methods Ninety-eight patients with GERD and 21 healthy controls were included in the study. Upper endoscopy, high-resolution manometry (HRM) and 24-hour multichannel intraluminal impedance-pH monitoring were performed in all patients. Three respiration cycles were chosen at the initial HRM resting frame and the value computed with distal contractile integral tool was then divided by the duration of the cycles to yield EGJ-CI. All the patients were treated with esomeprazole 20 mg twice-daily for 8 weeks. Results EGJ-CI was lower in the patients with GERD than that of the controls (P < 0.05). For patients with GERD, EGJ-CI was lower in those with hiatal hernia (P < 0.05). The new metric correlated with esophageal acid exposure in the supine position (P < 0.05), and it also negatively correlated to the total reflux episodes (P < 0.05). There was no significant difference on EGJ-CI between patients with and without response to the esomeprazole treatment (P = 0.627). Conclusions EGJ-CI reflected the dysfunction of the anti-reflux barrier in patients with GERD, but it had little impact on the esomeprazole response. PMID:27426485

    AIM To investigate the relationship between pathological oropharyngeal (OP) acid exposure and esophageal motility in patients with extra-esophageal syndromes. METHODS In this prospective study we enrolled consecutive outpatients with extra-esophageal symptoms suspected to be related to gastroesophageal reflux disease (GERD). We enrolled only patients with a reflux symptom index (RSI) score-higher than 13 and with previous lung, allergy and ear, nose and throat evaluations excluding other specific diagnoses. All patients underwent 24-h OP pH-metry with the Dx probe and esophageal high-resolution manometry (HRM). Patients were divided into two groups on the basis of a normal or pathological pH-metric finding (Ryan Score) and all manometric characteristics of the two groups were compared. RESULTS We examined 135 patients with chronic extra-esophageal syndromes. Fifty-one were considered eligible for the study. Of these, 42 decided to participate in the protocol. Patients were divided into two groups on the basis of normal or pathological OP acid exposure. All the HRM parameters were compared for the two groups. Significant differences were found in the median upper esophageal sphincter resting pressure (median 71 mmHg vs 126 mmHg, P = 0.004) and the median proximal contractile integral (median 215.5 cm•mmHg•s vs 313.5 cm•mmHg•s, P = 0.039), both being lower in the group with pathological OP acid exposure, and the number of contractions with small or large breaks, which were more frequent in the same group. This group also had a larger number of peristaltic contractions with breaks in the 20 mmHg isobaric contour (38.7% vs 15.38%, P < 0.0001). CONCLUSION In patients with suspected GERD-related extra-esophageal syndromes pathological OP acid exposure was associated with weaker proximal esophageal motility. PMID:27833390

    Gastroesophageal reflux disease (GERD) is a condition that develops when there is reflux of stomach contents, which typically manifests as heartburn and regurgitation. These esophageal symptoms are well recognized; however, there are extra-esophageal manifestations of GERD, which include asthma, chronic cough, laryngitis and sinusitis. With the rising incidence of asthma, there is increasing interest in identifying how GERD impacts asthma development and therapy. Due to the poor sensitivity of endoscopy and pH monitoring, empiric therapy with proton pump inhibitors (PPIs) is now considered the initial diagnostic step in patients suspected of having GERD-related symptoms. If unresponsive, diagnostic testing with pH monitoring off therapy and/or impedance/pH monitoring on therapy, may be reasonable in order to assess for baseline presence of reflux with the former and exclude continued acid or weakly acid reflux with the latter tests. PPI-unresponsive asthmatics, without overt regurgitation, usually have either no reflux or causes other than GERD. In this group, PPI therapy should be discontinued. In those with GERD as a contributing factor acid suppressive therapy should be continued as well as optimally treating other etiologies requiring concomitant treatment. Surgical fundoplication is rarely needed but in those with a large hiatal hernia, moderate-to-severe reflux by pH monitoring surgery might be helpful in eliminating the need for high-dose acid suppressive therapy.

    It is increasingly accepted that the effects of gastro-oesophageal reflux are not limited to the gastrointestinal tract. The adjacent respiratory structures are also at risk from material ejected from the proximal oesophagus as a result of the failure of anatomical and physiological barriers. There is evidence of the influence of reflux on several respiratory and otorhinological conditions and although in many cases the precise mechanism has yet to be elucidated, the association alone opens potential novel avenues of therapy to clinicians struggling to treat patients with apparently intractable respiratory complaints. This review provides a description of the airway reflux syndrome, its effects on the lung and current and future therapeutic options. PMID:23251752

    The aim of this paper is to investigate the diagnostic value of histopathologic score and the dilated intercellular space (DIS) in patients with gastroesophageal reflux disease (GERD) and functional heartburn (FH). Participants with GERD symptoms including reflux esophagitis, non-erosive reflux disease (NERD), Barrett's esophagus (BE), functional heartburn (FH), along with a control group with atypical GERD-like symptom (Sym-C), and asymptomatic healthy volunteers (H-C) were administered GERD questionnaire, and subjected to endoscopy and biopsies, as well as 24-hour pH-impedance monitoring. Biopsies were evaluated using standards from the 2011 Esohisto Project after Hematoxylin-Eosin staining. DIS was measured quantitatively under light microscopy. Among the total of 565 participants with qualified biopsy specimens, the mean DIS of the reflux esophagitis (RE) group was significantly wider compared with the other five groups. DIS in patients with GERD-like symptoms was significantly wider compared with the H-C. No significant differences were observed between NERD and FH. Results from 24-hour pH-impedance monitoring indicated that only the DIS of patients with acid reflux or the amount of acid reflux episodes in patients with DIS was significantly wider compared with patients with nonacid reflux or patients without DIS (P < 0.001). With DIS = 0.9 μm as the cutoff value, the sensitivity and specificity were 62.6% and 54.1%, respectively. Using the total histopathologic score > 3 as the diagnostic criterion, the sensitivity and specificity were 71.7% and 47.4%. DIS is closely associated with GERD and acid reflux. The diagnostic value of histological scores in lower esophagus in GERD is very similar to that of the quantitative measurement of DIS.

    Achalasia and gastroesophageal reflux disease (GERD) are on opposite ends of the spectrum of lower esophageal sphincter dysfunction. Heartburn is the main symptom of GERD. However, heartburn and regurgitation are frequently observed in patients who have achalasia. The diagnosis of achalasia might be delayed because these symptoms are misinterpreted as gastroesophageal reflux. Here, we reviewed the clinical characteristics of patients with the erroneous diagnosis of GERD who actually had untreated achalasia. PMID:27771944

    We have read with interest the paper by Roman C. and colleagues discussing the relationship between gastroesophageal reflux disease and atrial fibrillation. The review is presenting the available evidence for the common pathogenic mechanisms. However, from a cardiologist perspective, some available data were not highlighted in the review, cardiovascular involvement in gastroesophageal reflux is less assessed. Hypertension, obesity or diabetes mellitus are substrate for left atrial remodeling that initiate and sustained atrial fibrillation development. One of the pathophysiologic mechanisms in atrial fibrillation is the presence of a trigger. Gastroesophageal reflux could be only a trigger for this arrhythmia. We believe that atrial fibrillation should be considered as possible extraesophageal syndrome in the gastroesophageal reflux classification.

    Functional dyspepsia or nonulcer dyspepsia, and nonerosive reflux disease (NERD) or endoscopy-negative reflux disease, are common reasons for referral to a gastroenterologist. Although there is much confusion with regard to definition, recent research would suggest that these 2 conditions are linked and may represent components in the spectrum of the same disease entity, in terms of both symptoms and pathophysiology. Several theories have been proposed regarding the etiology of these disorders, including acid exposure, visceral hypersensitivity, impaired fundal accommodation, delayed gastric emptying, and Helicobacter pylori infection.

    Objectives The relationship between tooth erosion (TE) and gastroesophageal reflux (GER) in children has not been clearly established and there are no studies to determine the relationship with refluxate height, non-acid reflux and erosions. The aim of this study was to determine the relationship between TE and acid and non-acid GER measured using combined pH and multichannel intraluminal impedance (pH-MII). Methods We conducted a prospective cohort study of children presenting for pH-MII testing. Once consented, patients completed questionnaires about their reflux symptoms and diet, and then underwent pH-MII catheter placement and a dental examination. The Keels-Coffield erosion index was used to score extent and severity of TE. Reflux parameters of patients with and without TE were compared using Student's t test. Results Twenty-seven patients participated in the study, all of whom were on acid suppression at the time of pH-MII testing. Ten out of 27 patients (37%) had TE. There were significant positive correlations between acid reflux episodes (r=0.44, p=0.02), the % time that acid reflux was present in the distal esophagus (r=0.44, p=0.02), and reflux index (r=0.54, p=0.004) with number of TE in a given patient. The % time that acid reflux was present in the proximal esophagus was positively correlated with the number of teeth erosions per patient with borderline significance (r=0.38, p=0.05). Conclusions There was a positive correlation between acid reflux parameters and TE. Acid, rather than non-acid reflux, seems to have a significant role in the pathogenesis of TE. PMID:26230904

    Saliva is an important factor in the neutralization of the acidity of the refluxed material that comes from the stomach to the esophagus. The impairment of saliva transit from oral cavity to distal esophagus may be one of the causes of esophagitis and symptoms in gastroesophageal reflux disease (GERD). With the scintigraphic method, the transit of 2 mL of artificial saliva was measured in 30 patients with GERD and 26 controls. The patients with GERD had symptoms of heartburn and acid regurgitation, a 24-hour pH monitoring with more than 4.2% of the time with pH below four, 26 with erosive esophagitis, and four with non-erosive reflux disease. Fourteen had mild dysphagia for solid foods. Twenty-one patients had normal esophageal manometry, and nine had ineffective esophageal motility. They were 15 men and 15 women, aged 21-61 years, mean 39 years. The control group had 14 men and 12 women, aged 19-61 years, mean 35 years. The subjects swallowed in the sitting and supine position 2 mL of artificial saliva labeled with 18 MBq of (99m) Technetium phytate. The time of saliva transit was measured from oral cavity to esophageal-gastric transition, from proximal esophagus to esophageal-gastric transition, and the transit through proximal, middle, and distal esophageal body. There was no difference between patients and controls in the time for saliva to go from oral cavity to esophageal-gastric transition, and from proximal esophagus to esophageal-gastric transition, in the sitting and supine positions. In distal esophagus in the sitting position, the saliva transit duration was shorter in patients with GERD (3.0 ± 0.8 seconds) than in controls (7.6 ± 1.7 seconds, P = 0.03). In conclusion, the saliva transit from oral cavity to the esophageal-gastric transition in patients with GERD has the same duration than in controls. Saliva transit through the distal esophageal body is faster in patients with GERD than controls.

  14. Sex and Gender Differences in Gastroesophageal Reflux Disease

    It is important to understand sex and gender-related differences in gastroesophageal reflux disease (GERD) because gender-related biologic factors might lead to better prevention and therapy. Non-erosive reflux disease (NERD) affects more women than men. GERD symptoms are more frequent in patients with NERD than in those with reflux esophagitis. However, men suffer pathologic diseases such as reflux esophagitis, Barrett’s esophagus (BE), and esophageal adenocarcinoma (EAC) more frequently than women. The prevalence of reflux esophagitis is significantly increased with age in women, especially after their 50s. The mean age of EAC incidence in women is higher than in men, suggesting a role of estrogen in delaying the onset of BE and EAC. In a chronic rat reflux esophagitis model, nitric oxide was found to be an aggravating factor of esophageal injury in a male-predominant way. In addition, the expression of esophageal occludin, a tight junction protein that plays an important role in the esophageal defense mechanism, was up-regulated in women. This explains the male predominance of reflux esophagitis and delayed incidence of BE or EAC in women. Moreover, the symptoms such as heartburn, regurgitation, and extra-esophageal symptoms have been more frequently reported by women than by men, suggesting that sex and gender play a role in symptom perception. Differential sensitivity with augmented symptoms in women might have diagnostic and therapeutic influence. Furthermore, recent studies have suggested that hormone replacement therapy has a protective effect against esophageal cancer. However, an anti-inflammatory role of estrogen remains compelling, which means further study is necessary in this area. PMID:27703114

    Interstitial lung diseases comprise a heterogeneous group of pulmonary conditions that cause restrictive lung disease of poor prognosis, especially if growth failure, pulmonary hypertension and fibrosis appears. We report on the case of a girl of 11 years of age who suffered from severe nonallergic asthma in early childhood and who developed severe interstitial pulmonary disease caused by gastro-oesophageal reflux at the age of 8 years. This diagnosis was established by lung biopsy, bronchoalveolar lavage and a high amount of lipid-laden alveolar macrophages, 2-level pH measurement and oesophageal biopsy. Because therapy with oral and inhaled steroids failed and Omeprazol showed benificial effects, hemifundoplication according to THAL was performed. At present the lung function is clearly normal and there is no need of any medicaments. Following the history, we can assume the pathological gastro-oesophageal reflux to be the cause of the disease. It is important to state that there were no typical symptoms at any time pointing to gastro-oesophageal reflux disease. The development of pulmonary disease by pathological reflux is very often caused by "silent aspiration". Very typically there are no symptoms such as vomiting, heartburn and pain but only signs of chronic lung disease.

    Over the past decade, incidence of gastroesophageal reflux disease (GERD) showed an increasing trend resulting from factors, including lifestyle and dietary habits; however, both etiology and pathological mechanisms remain controversial. GERD occurs as a result of a variety of mechanisms and there is no single factor. Symptoms of GERD are often non-typical, with a likelihood of being overlooked by non-gastroenterology professionals. Therefore, improving GERD awareness in non-gastroenterology practitioners, along with early diagnosis and treatment, provide potential benefit to clinicians and patients alike. Increasing evidence suggests GERD has specific connections with a variety of non-digestive tract conditions, may contribute an aggravating compounding effect on other diseases, prolong hospitalization, and increase subsequent medical costs. This review considers and emphasizes the association between GERD and non-digestive tract conditions, including atrial fibrillation, chronic obstructive pulmonary disease, primary pulmonary fibrosis and energy metabolism related to diet.

    2010-01-01

    Gastro-oesophageal reflux (GOR) is a norma physiological process occurring daily in healthy infants with similar frequency in both breast- and bottle-fed infants. It is generally considered uncomplicated and self-limiting, resolving spontaneously by 12-14 months of age. In contrast, gastro-oesophageal reflux disease (GORD) is associated with more severe symptoms and, on occasions, oesophagitis. In the small percentage of cases that do not respond to simple feeding measures, a trial for 2-4 weeks using an extensively hydrolysed formula may be considered. Thickeners and antiregurgitation feeds may help with the frequency of overt regurgitation. Feeding difficulties can be a problem in infants with reflux, with some suffering extreme aversion to texture. In the small percentage of infants who experience faltering growth, high-calorie formulae can be used. In those with severe feeding difficulties or severe faltering growth, tube feeding may be required. Infants should ideally be managed within a multidisciplinary team including a speech and language therapist, psychologist, dietitian and paediatrician.

    Some patients with gastroesophageal reflux disease experience persistent reflux symptoms despite proton pump inhibitor therapy. These symptoms reduce their health-related quality of life. Our aims were to evaluate the relationship between proton pump inhibitor efficacy and health-related quality of life and to evaluate predictive factors affecting treatment response in Japanese patients. Using the gastroesophageal reflux disease questionnaire, 145 gastroesophageal reflux disease patients undergoing proton pump inhibitor therapy were evaluated and classified as responders or partial-responders. Their health-related quality of life was then evaluated using the 8-item Short Form Health Survey, the Pittsburgh Sleep Quality Index, and the Hospital Anxiety and Depression Scale questionnaires. Sixty-nine patients (47.6%) were partial responders. These patients had significantly lower scores than responders in 5/8 subscales and in the mental health component summary of the 8-item Short Form Health Survey. Partial responders had significantly higher Pittsburgh Sleep Quality Index and Hospital Anxiety and Depression Scale scores, including anxiety and depression scores, than those of responders. Non-erosive reflux disease and double proton pump inhibitor doses were predictive factors of partial responders. Persistent reflux symptoms, despite proton pump inhibitor therapy, caused mental health disorders, sleep disorders, and psychological distress in Japanese gastroesophageal reflux disease patients.

    The objective of the present work was to study voice disturbances in young children with gastroesophageal reflux disease. Diagnostic algorithm included direct transnasal examination of the larynx using an Olympus fibroscope (Japan), fibrogastroduodenoscopy, 24-hour potentiometry, biopsy of oesophageal mucosa, and acoustic analysis of the voice. A total of 26 children at the age from 8 months to 3 years with voice disturbances were examined, including 12 children below one year, 5 between 1 and 2 years, and 9 between 2 and 3 years. The main signs of laryngoesophageal reflux were dysphonia, oedema, hyperemia, and altered light reflex of mucous membrane of arytenoid cartilages, interarytenoid space, and vocal cords. It is concluded that voice disturbances are the most common symptoms of laryngoesophageal reflux in young children which necessitates the earliest possible endoscopic study of the larynx in all cases of dysphonia.

    Abstract Laparoscopic antireflux surgery is a frequently performed procedure for the treatment of gastroesophageal reflux in surgical clinics. Reflux can recur in between 3% and 30% of patients on whom antireflux surgery has been performed, and so revision surgery can be required due to recurrent symptoms or dysphagia in approximately 3% to 6% of the patients. The objective of this study is to evaluate the mechanism of recurrences after antireflux surgery and to share our results after revision surgery in recurrent cases. From 2001 to 2014, revision surgery was performed on 43 patients (31 men, 12 women) between the ages of 24 and 70 years. The technical details of the first operation, recurrence symptoms, endoscopy, and manometry findings were evaluated. The findings of revision surgery, surgical techniques, morbidity rates, length of hospitalization, and follow-up period were also recorded and evaluated. The first operation was Nissen fundoplication in 34 patients and Toupet fundoplication in 9 patients. Mesh hiatoplasty was performed for enforcement in 18 (41.9%) of these patients. The period between the first operation and the revision surgery ranged from 4 days to 60 months. The most common finding was slipped fundoplication and presence of hiatal hernia during revision surgery. Revision fundoplication and hernia repair with mesh reinforcement were used in 33 patients. The other techniques were Collis gastroplasty, revision fundoplication, and hernia repair without mesh. The range of follow-up period was from 2 to 134 months. Recurrence occurred in 3 patients after revision surgery (6.9%). Although revision surgery is difficult and it has higher morbidity, it can be performed effectively and safely in experienced centers.

    Gastro-esophageal reflux disease is a chronic, long standing disease. Spontaneous remission of GERD is rare and conservative management including life style modification measures is unlikely to relieve symptoms. Majority of patients with reflux disease require long-term acid suppressants. Proton pump inhibitors are the choice of drugs in management of these patients. The end point of treatment is not clear. Duration of treatment is individual based. The symptoms may be intermittent or on most days of the week. The treatment is therefore either a short course which may be for 8 to 12 weeks or 6 months, or continuous, intermittent or 'on-demand' basis. The maintenance therapy is with the lowest proton pump inhibitor (PPI) dose necessary for adequate symptom relief. Whether long-term PPI actually alters the natural history of reflux disease other than to reduce the incidence of peptic stricture is not known. Reported adverse effects due to PPI include Clostridium difficile colitis and bacterial gastroenteritis, osteoporosis, and vitamin B12 deficiency. Anti-reflux surgery is indicated for youngsters, those not willing for long-term PPI i.e. for years, large volume refluxers, especially the supine refluxers and bile refluxers.

  3. Gastro-Esophageal Reflux Disease in Healthy Older Children and Adolescents

    Gastro-esophageal reflux disease (GERD) in otherwise healthy older children and adolescents is commonly encountered in pediatric clinics and poses a complex treatment problem involving changes of diets and lifestyle. After an initial history taking and a physical examination, typical symptoms of GERD in older children and adolescenct are initially treated with the trials of acid suppressants. With an increase of severe cases, more and more GERD children have been evaluated with endoscopy, which helps to delineate an erosive esophagitis from a non-erosive reflux disease as they are presumed to have different pathogenesis. For the pediatric patients without a significant underlying disease, a reflux esophagitis can be treated adequately with acid suppressants. Recently, the rapid increase of children who are taking anti-reflux medication has brought up a serious alarm among pediatricians. Some at risk pediatric patients with recurrent and/or chronic GERD have been linked to adulthood GERD. In this paper, pediatric GERD with and without erosive esophagitis was reviewed along with treatment options and issues specifically for the otherwise healthy older children and adolescents in the primary clinics or the secondary hospitals.

    In 2102, a multidiscplinary guideline was developed on behalf of the Dutch Association of Pediatrics entitled 'Gastroesophageal reflux disease in children from 0-18 years'. The North American Society for Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN) and the European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) guideline from 2009 served for guidance. History and physical examination are usually sufficient for diagnosing gastroesophageal reflux disease. It is important to make a distinction between gastroesophageal reflux, a physiological phenomenon in children, and gastroesophageal reflux disease. In practice, medications are provided too often, especially in infants. Only children suffering from gastroesophageal reflux disease should be treated according to the therapeutical action plan.

    Gastroesophageal reflux disease (GERD), previously uncommon in Asia, has now become an important disease in the region. Although much variability exists between studies, most endoscopy-based studies show a prevalence of erosive esophagitis of more than 10%. Symptom-based studies also show a prevalence of 6-10%. Two longitudinal follow-up studies on GERD symptoms have shown an increase with time, and several endoscopy-based time trend studies have also shown a significant increase in erosive reflux esophagitis. Studies on Barrett's esophagus have been confounded by the description of short (SSBE) and long segment (LSBE) Barrett's esophagus. Great variation in prevalence rates has been reported. SSBE vary from 0.1% to more than 20% while LSBE vary from 1-2%. Of the putative causative factors, obesity has been the most important. Many studies have linked GERD-esophagitis as well as occurrence of reflux symptoms with an increase in body mass index (BMI), obesity, especially visceral or central obesity, and metabolic syndrome. A decline in Helicobacter pylori infection with growing affluence in Asia has been broadly thought to result in healthier stomachs and a higher gastric acid output resulting in reflux disease. However, variable results have been obtained from association and H. pylori eradication studies.

    Autonomic signs and symptoms could be of epileptic or nonepileptic origin, and the differential diagnosis depends on a number of factors which include the nature of the autonomic manifestations themselves, the occurrence of other nonictal autonomic signs/symptoms, and the age of the patient. Here, we describe twelve children (aged from ten months to six years at the onset of the symptoms) with Panayiotopoulos syndrome misdiagnosed as gastroesophageal reflux disease. Gastroesophageal reflux disease and Panayiotopoulos syndrome may represent an underestimated diagnostic challenge. When the signs/symptoms occur mainly during sleep, a sleep EEG or, if available, a polysomnographic evaluation may be the most useful investigation to make a differential diagnosis between autonomic epileptic and nonepileptic disorders. An early detection can reduce both the high morbidity related to mismanagement and the high costs to the national health service related to the incorrect diagnostic and therapeutic approaches. To decide if antiseizure therapy is required, one should take into account both the frequency and severity of epileptic seizures and the tendency to have potentially lethal autonomic cardiorespiratory involvement. In conclusion, we would emphasize the need to make a differential diagnosis between gastroesophageal reflux disease and Panayiotopoulos syndrome in patients with "an unusual" late-onset picture of GERD and acid therapy-resistant gastroesophageal reflux, especially if associated with other autonomic symptoms and signs.

    Belching may result from transient lower esophageal sphincter relaxation; therefore, it has been proposed that belching may be a manifestation of gastroesophageal reflux disease (GERD). This study was conducted to investigate the frequency of belching during esophagogastroduodenoscopy (EGD) and its association with GERD. A retrospective review was performed on prospectively collected clinical and endoscopic data from 404 subjects who underwent EGD without sedation from December 2012 to May 2013 in a training hospital in Korea. All detectable belching events during endoscopy were counted. Frequency and severity of belching events were compared between the group with and without GERD using an ordinal logistic regression model. There were 145 GERD patients (26 erosive reflux disease and 119 nonerosive reflux disease [NERD]). In the multivariable analysis, GERD was significantly associated with a higher frequency of belching events (odds ratio = 6.59, P < 0.001). Central obesity, female, and younger age were also risk factors for frequent belching during EGD. Subgroup analyses were performed in subjects without erosive reflux disease (n = 378) and NERD (n = 293). NERD was also a predictive factor for frequent belching during EGD (odds ratio = 6.61, P < 0.001), and the frequency of belching was significantly correlated with GERD severity according to the Los Angeles classification (P < 0.05). Frequent belching during EGD was associated with GERD, including NERD. Future research should focus on its adjuvant role in the diagnosis of GERD/NERD and the necessity for applying differentiated endoscopy strategies for GERD patients, leading to less discomfort during EGD in patients at risk for intolerability.

    2014-04-01

    Gastroesophageal reflux disease (GERD) is a common condition requiring considerable medical resources. The mainstay of therapy is proton pump inhibitors (PPIs), which are effective at reducing acid reflux. In patients who have refractory acid reflux and esophagitis despite high-dose PPI, or are intolerant of the side effects of PPI therapy, surgical fundoplication is the primary therapy. The risk and cost gap between medical therapy and surgery has resulted in substantial interest in less-invasive endoscopic therapies. In this review, we discuss the underlying physiology of GERD along with the anatomic hurdles that must be overcome to develop an effective antireflux procedure. We also review the current published literature and assess the clinical efficacy of the devices that have been studied or currently are being investigated. Despite promising early studies, many of the devices fall short in high-quality randomized controlled trials. Furthermore, the physiologic aberration resulting in GERD oftentimes is addressed inadequately. Although there is certainly a need for less-invasive, safe, and effective therapy for reflux, therapy will need to withstand the established clinical efficacy of both PPI and surgical fundoplication. At present, we have the luxury of time to wait for such a device to become available.

  11. Evaluation of Gastroesophageal Reflux Disease Using the Bravo Capsule pH System

    2016-01-01

    Gastroesophageal reflux disease (GERD) is a disease predominantly seen in the West but there is a rising trend in Asia. Ambulatory 24-hour catheter-based pH monitoring has been the de facto gold standard test for GERD that correlates symptoms with acid reflux episodes. However, drawbacks such as patients’ discomfort, and catheter displacement render the test as cumbersome and error-prone. The Bravo pH wireless system is designed to be user-friendly and has an added advantage of prolonged pH monitoring. The system is comparable to the catheter-based pH monitoring system in terms of diagnostic yield and symptom-reflux association. Indications include evaluation of patients with refractory GERD symptoms and prior to anti-reflux surgery. Bravo utilizes a wireless pH-sensing capsule with a complete prepackaged system, and a data processing software. The capsule may be positioned indirectly using endoscopic or manometric landmarks or under direct endoscopic guidance. Optimal threshold cut-off values are yet to be standardized but based on available studies, for the Asian population, it may be recommended for total % time pH < 4 of 5.8 over 48 hours. Cost is a limitation but capsule placement is relatively safe although technical failures may be seen in small percentage of cases. PMID:26717929

If the excellent results and safety and efficacy of this technique are confirmed in the long term, it could revolutionize the management of gastroesophageal reflux disease. Also of note this year was the presentation of multiple studies validating a new technique, peroral endoscopic myotomy (POEM) for the endoscopic treatment of achalasia. This technique seems to have excellent efficacy and safety.

  13. Dilated intercellular spaces and chronic cough as an extra-oesophageal manifestation of gastrooesophageal reflux disease.

    PubMed

    Orlando, Roy C

    2011-06-01

    Chronic cough is one of the extra-oesophageal manifestations of gastrooesophageal reflux disease (GORD). It is presumed to occur either directly by microaspiration of acidic gastric contents into the airway or indirectly by a reflex triggered by contact of acidic refluxates with the oesophageal epithelium in GORD. How contact of the oesophageal epithelium with acidic refluxates promotes sensitization for chronic cough is unknown, but like heartburn, which is a necessary accompaniment, it requires acid activation of nociceptors within the oesophageal mucosa. Dilated intercellular spaces within the oesophageal epithelium, a reflection of an increase in paracellular permeability, is a histopathologic feature of both erosive and non-erosive forms of GORD. Since it correlates with the symptom of heartburn, it is hypothesized herein that the increase in paracellular permeability to acid reflected by dilated intercellular spaces in oesophageal epithelium also serves as mediator of the signals that produce the reflex-induced sensitization for cough--a sensitization that can occur centrally within the medullary Nucleus Tractus Solitarius or peripherally within the tracheobronchial tree.

    2016-01-28

    Gastroesophageal reflux disease (GERD) is a frequently encountered disorder. Obesity is an important risk factor for GERD, and there are several pathophysiologic mechanisms linking the two conditions. For obese patients with GERD, much of the treatment effort is focused on weight loss and its consistent benefit to symptoms, while there is a relative lack of evidence regarding outcomes after novel or even standard medical therapy is offered to this population. Physicians are hesitant to recommend operative anti-reflux therapy to obese patients due to the potentially higher risks and decreased efficacy, and these patients instead are often considered for bariatric surgery. Bariatric surgical approaches are broadening, and each technique has emerging evidence regarding its effect on both the risk and outcome of GERD. Furthermore, combined anti-reflux and bariatric options are now being offered to obese patients with GERD. However, currently Roux-en-Y gastric bypass remains the most effective surgical treatment option in this population, due to its consistent benefits in both weight loss and GERD itself. This article aims to review the impact of both conservative and aggressive approaches of obesity treatment on GERD.

  15. Extra-esophageal manifestations of gastroesophageal reflux disease: diagnosis and treatment.

    PubMed

    Hom, Christopher; Vaezi, Michael F

    2013-08-01

    Gastroesophageal reflux disease (GERD) is a common disease that is often diagnosed based on typical symptoms of heartburn and regurgitation. In addition to these more classic manifestations, GERD is increasingly associated with extra-esophageal symptoms, including chronic cough, asthma, laryngitis, and dental erosions. Due to the poor sensitivity of endoscopy and pH monitoring, and the poor specificity of laryngoscopy, empiric therapy with proton pump inhibitors (PPIs) is now considered the initial diagnostic step in patients suspected of having GERD-related symptoms. For those who improve with PPIs, GERD is the presumed etiology, but for those who remain unresponsive to such therapy, further diagnostic testing with impedance/pH monitoring may be necessary in order to exclude refractory acid or weakly acid reflux. In those with normal test results despite PPI therapy and continued symptoms, causes other than GERD may be pursued. Recent data suggest that in patients with extra-esophageal symptoms, objective findings of moderate-sized hiatal hernia and moderate reflux on pH testing may predict response to acid suppressive therapy. PPI-unresponsive patients usually have causes other than GERD for their extra-esophageal symptoms and continued PPI therapy in this group is not recommended.

    BACKGROUND Currently, it has been demonstrated that gastroesophageal reflux disease (GERD) is one of the most important disorders of the digestive system and the commixture of regular diet has a significant influence on its incidence, symptoms, and prognosis. The purpose of this study was to evaluate the effect of zinc supplementation, in combination with PPIs(Proton pump inhibitors), on the improvement of GERD symptoms. METHODS In a randomized double blind clinical trial, patients with reflux symptoms, who had obtained Reflux Disease Questionnaire (RDQ) score more than 8, were included and all the demographic features were recorded. Then, using upper gastrointestinal (GI) endoscopy, all the patients were divided into two groups as having non-erosive reflux disorder (NERD),or erosive reflux disorder (ERD). At the next step, based on random block statistical method, we divided the two groups into two subgroups; the drug subgroup [treated with PPIs (40 mg pantoprazole/daily), changing life style, and 220 mgzinc capsules daily] and the placebo subgroup [treated with PPIs, changing life style, and placebo]. After 3 months, we analyzed all data and the RDQ questionnaire was filled out for each patient. This project has been registered in Iranian Registry of Clinical Trials (IRCT) and all data were analyzed using SPSS software version 2. RESULTS A total of 140 patients (81 women and 59 men) with mean age of 42.78±11.5 years were included with 70 patients in each group. The most frequent presentations were heart burn (45.7%), and acid regurgitation (39.3%). The RDQ scores decreased after intervention in both drug (p<0.001) and placebo groups (p<0.001), which were statistically significant. But the difference of RDQ scores between the drug group and placebo group was not statistically significant (p=0.086). CONCLUSION Zinc supplementation cannot improve the severity of GERD.

    Gastroesophageal reflux disease affects almost 20% of the population in the United States. Today, proton pump inhibitors are the most frequently prescribed drugs, with an estimated cost of 10 billion dollars per year. Although these medications control heartburn in the majority of patients, other symptoms such as regurgitation and respiratory symptoms often are not controlled, particularly in patients with large hiatal hernias. In these patients a properly performed laparoscopic fundoplication controls esophageal and extraesophageal symptoms and avoids life-long medical therapy. Key elements for the success of a fundoplication are careful patient selection, a complete preoperative evaluation, and a properly executed operation.

    Vesicoureteric reflux (VUR) is a common congenital urinary tract defect that predisposes children to recurrent kidney infections. Kidney infections can result in renal scarring or reflux nephropathy defined by the presence of chronic tubulo-interstitial inflammation and fibrosis that is a frequent cause of end-stage renal failure. The discovery of mouse models with VUR and with reflux nephropathy has provided new opportunities to understand the pathogenesis of these conditions and may provide insight on the genes and the associated phenotypes that need to be examined in human studies.

    Gastro-esophageal reflux disease (GERD) is one of the most prevalent chronic diseases. Although proton pump inhibitors (PPIs) represent the mainstay of treatment both for healing erosive esophagitis and for symptom relief, several studies have shown that up to 40% of GERD patients reported either partial or complete lack of response of their symptoms to a standard PPI dose once daily. Several mechanisms have been proposed as involved in PPIs resistance, including ineffective control of gastric acid secretion, esophageal hypersensitivity, ultrastructural and functional changes in the esophageal epithelium. The diagnostic evaluation of a refractory GERD patients should include an accurate clinical evaluation, upper endoscopy, esophageal manometry and ambulatory pH-impedance monitoring, which allows to discriminate non-erosive reflux disease patients from those presenting esophageal hypersensitivity or functional heartburn. Treatment has been primarily based on doubling the PPI dose or switching to another PPI. Patients with proven disease, not responding to PPI twice daily, are eligible for anti-reflux surgery.

    BACKGROUND—Although antisecretory medications such as histamine type II receptor antagonists or proton pump inhibitors have been used to treat reflux oesophagitis, a considerable number of patients do not achieve complete mucosal healing or suffer from either sustained symptoms or ensuing complications, suggesting other damaging factors or impaired mucosal resistance are also involved in the pathogenesis of reflux oesophagitis.
AIMS—The present study was designed to evaluate oxidative stress as the major pathogenic factor of reflux oesophagitis and to determine the usefulness of antioxidants in the treatment of reflux oesophagitis.
MATERIALS AND METHODS—Reflux oesophagitis was induced by insertion of a 3 mm calibre ring into the duodenum, 1 cm distal to the ligament of Treitz, in Sprague-Dawley rats.
RESULTS—DA-9601, a novel antioxidant substance, significantly attenuated the gross and histopathological scores of reflux oesophagitis compared with those treated with ranitidine alone or reflux oesophagitis controls in a dose dependent manner. Only scattered erosions were observed in the antioxidant pretreated group but acid suppression by ranitidine was not effective in decreasing the severity of reflux oesophagitis. Significantly increased amounts of malondialdehyde (MDA), increased nuclear factor κB (NFκB) activation, and depletion of reduced glutathione (GSH) were observed in experimentally induced reflux oesophagitis. DA-9601 pretreatment attenuated the decrement in mucosal GSH levels and decreased MDA formation significantly. DA-9601 treatment caused significant reductions in activation of NFκB transcription factor, especially the p50 subunit, in accordance with the significantly higher levels of inhibitory protein of NFκB expression.
CONCLUSION—Reflux oesophagitis caused considerable levels of oxidative stress in the oesophageal mucosa and antioxidant treatment should be considered as supplementary therapy in the prevention or treatment

    Improving the quality of healthcare delivery is a cornerstone of modern medical care shared between all stakeholders. However, effectively improving quality requires both an understanding of the tenets of healthcare quality and how they relate to an individual disease process. This is especially important for common diseases, such as gastroesophageal reflux disease (GERD), where wide variations in practice exist. The high prevalence of GERD coupled with wide variation in clinical approach results in significant economic burden and poor quality of care. Thus, GERD serves as a useful framework to highlight the opportunities and current challenges of delivering high-quality care. In this article, we identify quality metrics in GERD and the areas in need of research to improve the quality of the management of GERD. Additionally, we suggest strategies for improvement as it relates to the proper diagnostic testing utilization and the decision-making process.

    Background and Objectives: Helicobacter pylori infection represents one of the most common and medically prominent infections worldwide. Gastroesophageal reflux disease (GERD) has a multifactorial etiology. The nature of the relationship between Helicobacter pylori infection (HP) and reflux esophagitis is still not clear. This study is designed to find the influence of HP on GERD. Patients and Methods: The study was conducted retrospectively at Sakarya Newcity Hospital between January 2006 and January 2009. Data were collected on patient's age, sex, weight, the grade of GERD and the severity of HP. Results: There were 1,307 women and 1,135 men in this review with a mean age of 39,54 (range, 17 to 70) years. Helicobacter pylori positive (1 to 3 severity) was frequently seen in patients with GERD. A statistically significant relationship was found between HP positivity and the grade of GERD. The Helicobacter pylori infection (1 to 3 severity) was found in 1,437 (82.5%) of patients with GERD in our series. Conclusions: Controversy still exists about the association between GERD and HP infection. Based on our findings, significant evidence suggests the potential role of HP infection in the development of GERD. Also, the current data provide sufficient evidence to define the relationship between GERD and HP infection. PMID:23477175

    Gastro-oesophageal reflux disease (GORD) and morbid obesity are entities with increasing prevalence. New clinical strategies are cornerstones for their management. The aim of this study was to assess the prevalence of heartburn during sleep (HDS) and whether this symptom predicts the presence of objective GORD parameters and increased heartburn perception in morbidly obese patients. Ninety-one consecutive morbidly obese patients underwent clinical evaluation, upper gastrointestinal endoscopy and oesophageal pH monitoring. HDS was characterized when patients replied positively to the question, 'Does heartburn wake you from sleep?'. A General Score for Heartburn (GSH) ranging between 0 and 5 was assessed with the question 'How bad is your heartburn?'. HDS was reported by 33 patients (36%). More patients with HDS had abnormal acid contact time or reflux oesophagitis than patients without HDS (94%vs 57%, P < 0.001). HDS had a positive predictive value of 94% (0.95 CI 82-98), sensitivity of 48% (0.95 CI 37-60%) and specificity of 93% (0.95 CI 77-98%) for detection of GORD. A higher proportion of patients with HDS perceived heartburn preceded by acid reflux in diurnal (39%vs 9%; P < 0.001) periods during pH-metry. HDS patients showed higher GSH (2.4 +/- 0.5 vs 1.7 +/- 0.4; P < 0.0001) compared with patients who denied HDS but reported diurnal heartburn. HDS occurs in a significant minority of patients with morbid obesity and has high positive predictive value for GORD. Symptomatic reflux during the sleep seems to be a marker of increased heartburn perception in this population.

    AIM: To evaluate the effect of a novel alginate-based compound, Faringel, in modifying reflux characteristics and controlling symptoms. METHODS: In this prospective, open-label study, 40 patients reporting heartburn and regurgitation with proven reflux disease (i.e., positive impedance-pH test/evidence of erosive esophagitis at upper endoscopy) underwent 2 h impedance-pH testing after eating a refluxogenic meal. They were studied for 1 h under basal conditions and 1 h after taking 10 mL Faringel. In both sessions, measurements were obtained in right lateral and supine decubitus positions. Patients also completed a validated questionnaire consisting of a 2-item 5-point (0-4) Likert scale and a 10-cm visual analogue scale (VAS) in order to evaluate the efficacy of Faringel in symptom relief. Tolerability of the treatment was assessed using a 6-point Likert scale ranging from very good (1) to very poor (6). RESULTS: Faringel decreased significantly (P < 0.001), in both the right lateral and supine decubitus positions, esophageal acid exposure time [median 10 (25th-75th percentil 6-16) vs 5.8 (4-10) and 16 (11-19) vs 7.5 (5-11), respectively] and acid refluxes [5 (3-8) vs 1 (1-1) and 6 (4-8) vs 2 (1-2), respectively], but increased significantly (P < 0.01) the number of nonacid reflux events compared with baseline [2 (1-3) vs 3 (2-5) and 3 (2-4) vs 6 (3-8), respectively]. Percentage of proximal migration decreased in both decubitus positions (60% vs 32% and 64% vs 35%, respectively; P < 0.001). Faringel was significantly effective in controlling heartburn, based on both the Likert scale [3.1 (range 1-4) vs 0.9 (0-2); P < 0.001] and VAS score [7.1 (3-9.8) vs 2 (0.1-4.8); P < 0.001], but it had less success against regurgitation, based on both the Likert scale [2.6 (1-4) vs 2.2 (1-4); P = not significant (NS)] and VAS score [5.6 (2-9.6) vs 3.9 (1-8.8); P = NS]. Overall, the tolerability of Faringel was very good 5 (2-6), with only two patients reporting modest adverse

  5. Role of tight junction proteins in gastroesophageal reflux disease

    PubMed Central

    2012-01-01

    Background Gastroesophageal reflux disease (GERD) is associated with impaired epithelial barrier function that is regulated by cell-cell contacts. The aim of the study was to investigate the expression pattern of selected components involved in the formation of tight junctions in relation to GERD. Methods Eighty-four patients with GERD-related symptoms with endoscopic signs (erosive: n = 47) or without them (non-erosive: n = 37) as well as 26 patients lacking GERD-specific symptoms as controls were included. Endoscopic and histological characterization of esophagitis was performed according to the Los Angeles and adapted Ismeil-Beigi criteria, respectively. Mucosal biopsies from distal esophagus were taken for analysis by histopathology, immunohistochemistry and quantitative reverse-transcription polymerase chain reaction (RT-PCR) of five genes encoding tight junction components [Occludin, Claudin-1, -2, Zona occludens (ZO-1, -2)]. Results Histopathology confirmed GERD-specific alterations as dilated intercellular spaces in the esophageal mucosa of patients with GERD compared to controls (P < 0.05). Claudin-1 and −2 were 2- to 6-fold upregulation on transcript (P < 0.01) and in part on protein level (P < 0.015) in GERD, while subgroup analysis of revealed this upregulation for ERD only. In both erosive and non-erosive reflux disease, expression levels of Occludin and ZO-1,-2 were not significantly affected. Notably, the induced expression of both claudins did not correlate with histopathological parameters (basal cell hyperplasia, dilated intercellular spaces) in patients with GERD. Conclusions Taken together, the missing correlation between the expression of tight junction-related components and histomorphological GERD-specific alterations does not support a major role of the five proteins studied in the pathogenesis of GERD.

    Numerous questionnaires with a wide variety of characteristics have been developed for the assessment of gastroesophageal reflux disease (GERD). Four well-defined dimensions are noticeable in these GERD questionnaires, which are symptoms, response to treatment, diagnosis, and burden on the quality of life of GERD patients. The aim of this review is to develop a complete overview of all available questionnaires, categorized per dimension of the assessment of GERD. A systematic search of the literature up to January 2013 using the Pubmed database and the Embase database, and search of references and conference abstract books were conducted. A total number of 65 questionnaires were extracted and evaluated. Thirty-nine questionnaires were found applicable for the assessment of GERD symptoms, three of which are generic gastrointestinal questionnaires. For the assessment of response to treatment, 14 questionnaires were considered applicable. Seven questionnaires with diagnostic purposes were found. In the assessment of quality of life in GERD patients, 18 questionnaires were found and evaluated. Twenty questionnaires were found to be used for more than one assessment dimension, and eight questionnaires were found for GERD assessment in infants and/or children. A wide variety of GERD questionnaires is available, of which the majority is used for assessment of GERD symptoms. Questionnaires differ in aspects such as design, validation and translations. Also, numerous multidimensional questionnaires are available, of which the Reflux Disease Questionnaire is widely applicable. We provided an overview of GERD questionnaires to aid investigators and clinicians in their search for the most appropriate questionnaire for their specific purposes.

    To determine the incidence of renal scarring among patients with primary vesicoureteral reflux (VUR) and the possible risk factor(s), we studied 90 children (60 girls and 30 boys) with VUR followed in the Pediatric Nephrology Unit at the Ege University Hospital from 1998 to 2003. All the patients were assessed for VUR grade by voiding cystoureterography and for presence of renal scarring by (99 m) technetium dimercapto-succinic acid scintigraphy. All infants with VUR were given low-dose prophylactic antibiotics and followed-up until resolution of the reflux. Grade of reflux and number of urinary tract infection (UTI) episodes (≥3) were found to be statistically significant risk factors for renal scarring (P <0.05). However, gender, familial history and laterality of the disease were not found to be statistically significant risk factors (P >0.05). Similarly, there was no statistically significant difference of frequency of renal scarring among the different age groups (P >0.05). We conclude that recurrences of UTI and VUR severity are significant risk factors for renal scarring in children with VUR. Therefore, identification of VUR at an early age may offer the opportunity to prevent episodes of UTI and possible formation of renal scars that may result in end-stage renal failure.

  8. Reflux and cough.

    2010-02-01

    Reflux is a significant contributor to cough in otolaryngology practice; cough is just one marker of its many negative effects on the upper aerodigestive tract. Reflux causes cough both by direct irritation/inflammation and by increasing sensitivities to other noxious agents. Detailed and diligent clinical evaluation, including laryngoscopy, is useful in advancing the working diagnosis of reflux-associated cough. Supplemental testing, including impedance monitoring of esophageal refluxate, can be important to evaluate for both acidic and nonacidic reflux exposure. The mainstay of treatment continues to be dietary and other lifestyle interventions and drug therapy. Although proton-pump inhibitor therapy is effective in most patients, especially those with acid reflux disease, prokinetic therapy is probably very important with those with combined acid and nonacid disease and those with pure nonacid disease. It is likely that failure to improve can be due to behavioral and drug compliance issues. Antireflux surgery can yield long-lasting positive outcomes in carefully selected patients despite the lower efficacy of treatment for primary upper aerodigestive tract symptoms (cough, hoarseness, sore throat) compared with heartburn and regurgitation.

    Background Laryngopharyngeal reflux (LPR) disease has many symptoms such as globus pharyngeus, excessive throat clearing and hoarseness. The aim of this study was to investigate the effect of stellate ganglion block (SGB) in addition to proton pump inhibitors (PPI) on LPR. Methods Fifty patients complaining of more than 3 typical LPR symptoms for over 3 months were enrolled in the study. The P group took PPI for 8 weeks. The SP group took PPI and interwent a series of 8 SGB procedure once a week during the period of treatment. The blocks were performed one at a time unilaterally on the right and left stellate ganglions by injecting 1% mepivacaine 6 ml. We evaluated the reflux symptom index (RSI) before treatment and following 4 weeks and 8 weeks of treatment in both groups. Results After 4 weeks of treatment, the RSI of the P group decreased, but not significantly, to 16.6 ± 6.8 compared with the baseline value of 19.2 ± 2.7 (P = 0.093), whereas the RSI of the SP group decreased significantly to 9.8 ± 3.3 compared with the baseline value of 19.0 ± 4.7 (P = 0.000). After 8 weeks of treatment, the RSI of the P group decreased significantly to 13.7 ± 6.7 (P = 0.001) and the RSI of the SP group also decreased significantly to 7.7 ± 3.4 (P = 0.000). There were significant differences in the RSI between the two groups after 4 weeks (P = 0.000) and 8 weeks (P = 0.001) of treatment. Conclusions The symptoms of LPR improved earlier when PPI therapy was combined with SGB compared with PPI therapy alone. PMID:23741567

    OBJECTIVE: The authors examined indications, evaluations, and outcomes after laparoscopic fundoplication in patients with gastroesophageal reflux through this single-institution study. SUMMARY OF BACKGROUND DATA: Laparoscopic fundoplication has been performed for less than 5 years, yet the early and intermediate results suggest that this operation is safe and equivalent in efficacy to open techniques of antireflux surgery. METHODS: Over a 4-year period, 300 patients underwent laparoscopic Nissen fundoplication (252) or laparoscopic Toupet fundoplication (48) for gastroesophageal reflux refractory to medical therapy or requiring daily therapy with omeprazole or high-dose H2 antagonists. Preoperative evaluation included symptom assessment, esophagogastroduodenoscopy, 24-hour pH evaluation, and esophageal motility study. Physiologic follow-up included 24-hour pH study and esophageal motility study performed 6 weeks and 1 to 3 years after operation. RESULTS: The most frequent indication for surgery was the presence of residual typical and atypical gastroesophageal reflux symptoms (64%) despite standard doses of proton pump inhibitors. At preoperative evaluation, 51% of patients had erosive esophagitis, stricture, or Barrett's metaplasia. Ninety-eight percent of patients had an abnormal 24-hour pH study. Seventeen percent had impaired esophageal motility and 2% had aperistalsis. There were four conversions to open fundoplication (adhesions, three; large liver, one). Intraoperative technical difficulties occurred in 19(6%) patients and were dealt with intraoperatively in all but 1 patient (bleeding from enlarged left liver lobe). Minor complications occurred in 6% and major complications in 2%. There was no mortality. Median follow-up was 17 months. One year after operation, heartburn was absent in 93%. Four percent took occasional H2 antagonists, and 3% were back on daily therapy. Atypical reflux symptoms (e.g., asthma, hoarseness, chest pain, or cough) were eliminated

    Obesity is an epidemic that is known to play a role in the development of gastro-esophageal reflux disease (GERD). Studies have shown that increasing body mass index plays a role in the incompetence of the gastroesophageal junction and that weight loss and lifestyle modifications reduce the symptoms of GERD. As a method of producing effective and sustainable weight loss, bariatric surgery plays a major role in the treatment of obesity. We reviewed the literature on the effects of different types of bariatric surgery on the symptomatic relief of GERD and its complications. Roux-en-Y gastric bypass was considered an effective method to alleviate symptoms of GERD, whereas laparoscopic sleeve gastrectomy appeared to increase the incidence of the disease. Adjustable gastric banding was seen to initially improve the symptoms of GERD; however, a subset of patients experienced a new onset of GERD symptoms during long-term follow-up. The literature suggests that different surgeries have different impacts on the symptomatology of GERD and that careful assessment may be needed before performing bariatric surgery in patients with GERD.

    2013-01-01

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

    AIM To elucidate the factors associated with residual gastroesophageal reflux disease (GERD) symptoms in patients receiving proton pump inhibitor (PPI) maintenance therapy in clinical practice. METHODS The study included 39 GERD patients receiving maintenance PPI therapy. Residual symptoms were assessed using the Frequency Scale for Symptoms of GERD (FSSG) questionnaire and the Gastrointestinal Symptom Rating Scale (GSRS). The relationships between the FSSG score and patient background factors, including the CYP2C19 genotype, were analyzed. RESULTS The FSSG scores ranged from 1 to 28 points (median score: 7.5 points), and 19 patients (48.7%) had a score of 8 points or more. The patients’ GSRS scores were significantly correlated with their FSSG scores (correlation coefficient = 0.47, P < 0.005). In erosive esophagitis patients, the FSSG scores of the CYP2C19 rapid metabolizers (RMs) were significantly higher than the scores of the poor metabolizers and intermediate metabolizers (total scores: 16.7 ± 8.6 vs 7.8 ± 5.4, P < 0.05; acid reflux-related symptom scores: 12 ± 1.9 vs 2.5 ± 0.8, P < 0.005). In contrast, the FSSG scores of the CYP2C19 RMs in the non-erosive reflux disease patients were significantly lower than those of the other patients (total scores: 5.5 ± 1.0 vs 11.8 ± 6.3, P < 0.05; dysmotility symptom-related scores: 1.0 ± 0.4 vs 6.0 ± 0.8, P < 0.01). CONCLUSION Approximately half of the GERD patients receiving maintenance PPI therapy had residual symptoms associated with a lower quality of life, and the CYP2C19 genotype appeared to be associated with these residual symptoms.

    Abstract Symptoms of refractory gastroesophageal reflux disease (GERD) are commonly encountered in clinical practice. The aim of this study was to analyze the data obtained from questionnaires, high-resolution manometry (HRM), and ambulatory impedance-pH monitoring in patients with persisting GERD symptoms and to explore the possible underlying causes for this clinical presentation. After completing the questionnaires, the selected patients underwent endoscopy, HRM, and ambulatory impedance-pH monitoring. Based on the results of these investigations, we divided the patients into 4 groups: reflux esophagitis (RE), hypersensitive esophagus (HE), functional heartburn (FH), and nonerosive gastroesophageal reflux disease (NERD). The data from 342 patients were analyzed. One hundred twenty-nine (37.72%) patients experienced refractory GERD symptoms related to acid reflux. The scores on some scales in the Gastrointestinal Symptom Rating Scale (GSRS) questionnaire differed significantly among groups (all P < 0.05). Liquid reflux occurred more frequently in patients with GERD (RE and NERD), while gas reflux was more common in non-GERD patients (FH and HE; all P < 0.05). The RE and NERD groups showed more percent bolus exposure time (BET) when upright (all P < 0.05). Acid exposure time (AET) in the RE and NERD groups was longer than that in the HE and FH groups (all P < 0.05). Fewer than half of the patient symptoms were related to acid reflux. The GSRS questionnaire may be an optimal indicator for patients with refractory GERD symptoms. BET and AET are useful indices to distinguish GERD from other diseases. Gas reflux is probably related to persisting symptoms in FH and HE patients. PMID:28151867

The patient developed recurrent disease and returned to the operating room for repeat TURBT, circumcision, and administration of intravesical mitomycin C. The patient developed balanitis xerotica obliterans 4 years post-circumcision, requiring self-dilation with a catheter. He subsequently developed 3 consecutive episodes of left-sided pyelonephritis. Further investigation with voiding cystourethrogram (VCUG) revealed Grade 3, left-sided vesicoureteral reflux (VUR). Due to existing comorbidities, the patient elected treatment with endoscopic dextranomer/hyaluronic acid injection. A post-operative VCUG demonstrated complete resolution of left-sided VUR. This patient has remained symptom free for 8 months post-injection, with no episodes of pyelonephritis. PMID:27162514

    Introduction Nutrition can contribute to the development of gastroesophageal reflux disease (GERD). The relevant studies often provide contradictory results. Aim To determine GERD risk factors associated with dietary habits. Material and methods A total of 513 subjects were included. The study group consisted of adults with a recent clinically confirmed diagnosis of GERD, and the control group were healthy adults. The research tool was a proprietary questionnaire. Risk factors were evaluated by logistic regression models. Results An association was found between the severity of typical GERD symptoms and a certain diet (p < 0.001). The symptoms were experienced more often after fatty, fried, sour, or spicy food and sweets. The univariate logistic regression analysis showed the following risk factors: eating 1–2 meals per day (OR = 3.50, 95% CI: 1.75–6.98), everyday consumption of peppermint tea (OR = 2.00, 95% CI: 1.14–3.50), and eating one, big meal in the evening instead of dinner and supper (OR = 1.80, 95% CI: 1.05–3.11). The multivariate analysis confirmed that frequent peppermint tea consumption was a risk factor (OR = 2.00, 95% CI: 1.08–3.70). Conclusions Taking into consideration the results of this study, it seems that patients should be recommended to eat more than three meals a day and eat dinner and supper at appropriate times instead of one, big meal in the evening. The role of frequent peppermint tea consumption in GERD development requires further studies. PMID:25396005

    Gastroesophageal reflux is one of the most common reasons for referrals to paediatricians or paediatric gastroenterologists. Gastric acid-buffering agents, mucosal surface barriers and gastric anti-secretory agents are the main groups of medications currently used for treating gastroesophageal reflux disease (GERD) in children. Recently, the use of proton pump inhibitors (PPIs) for the treatment of GERD in children has increased considerably. Their effectiveness in healing erosive oesophagitis in paediatric subjects and in improving GERD symptoms has been established in many studies. However, the effectiveness in other clinical conditions and the long-term safety of PPIs for paediatric GERD have not been fully established yet and thus are still under debate. Therefore, the aim of this article is to provide a comparative review of the efficacy, safety and tolerability of PPIs in paediatric GERD. The available data suggest that short-term use of PPIs is well tolerated. Adverse events tend to be of a mild-to-moderate nature, with headache being the most frequently reported treatment-related adverse event. However, further well-designed trials and observational studies are still needed to clarify the efficacy and safety of PPIs in the paediatric population, especially in infants under the age of 12 months.

    The most important novel findings presented on oesophageal disease in DDW 2015 were the following: 1) GERD: a) hypervigilance seems to be a key pathogenic factor in reflux symptoms refractory to PPI; b) post-reflux swallowing-induced peristaltic waves could be an excellent diagnostic criterion for GERD; c) laryngeal pH-metry is not useful in the diagnosis of extra-oesophageal symptoms; d) the recommendation of weight loss adequately recorded in the clinical reports of patients with GERD and obesity or overweight is an excellent quality indicator and is associated with better outcomes. 2) Barrett's oesophagus: a) persistent low-grade dysplasia in more than one endoscopy and a diagnosis of "indefinite for dysplasia" are associated with a high risk of neoplastic progression; b) narrow-band imaging allows areas of dysplasia on Barrett's oesophagus to be identified with high sensitivity and specificity; c) initial endoscopy fails to identify a high percentage of advanced neoplasms in Barrett's oesophagus. Early re-endoscopy should be considered; d) endoscopists specialized in Barret's oesophagus obtain a much higher yield in the diagnosis of advanced lesions. Patients at high risk-men, older patients, smokers and those with long-segment Barrett's oesophagus-could benefit from follow-up in a referral center. 3) Achalasia: POEM seems safe and effective, independently from patient characteristics (age, comorbidity) and the technical variations used. 4) Eosinophilic esophagitis: topical budesonide and exclusion diets are reasonably effective in PPI non-responders.

    Gastroesophageal reflux disease is a chronic disease with a high incidence worldwide. The various symptoms have substantial impact on the quality of life of affected individuals. A long-term self-management program can increase the ability of patients to make behavioral changes, and health outcomes can improve as a consequence. This study's aim was to evaluate the effectiveness of a self-management program for gastroesophageal reflux disease. A total of 115 patients with gastroesophageal reflux disease were allocated to the experimental group and the control group. The former received self-management intervention along with conventional drug therapy, whereas the latter received standard outpatient care and conventional drug therapy. After the clinical trial, the control group also received the same self-management intervention. The levels of self-management behaviors, self-efficacy, gastroesophageal reflux disease symptoms, and psychological condition were compared. Those in the experimental group demonstrated significantly higher self-efficacy for managing their illness, showed positive changes in self-management behaviors, and had comparatively better remission of symptoms and improvement in psychological distress. The program helped patients with gastroesophageal reflux disease self-manage their illness as possible. PMID:27684637

    Treatment of gastroesophageal reflux disease in the United States today is binary, with the majority of patients with gastroesophageal reflux disease being treated with antisecre-tory medications and a minority of patients, typically those with volume regurgitation, undergoing Nissen fundoplication. However, there has been increasing dissatisfaction with proton pump inhibitor therapy among a significant number of patients with gastroesophageal reflux disease owing to cost, side effects, and refractory symptoms, and there has been a general reluctance to undergo surgical fundoplication due to its attendant side-effect profile. As a result, a therapy gap exists for many patients with gastroesophageal reflux disease. Alternative techniques are available for these gap patients, including 2 endoscopic fundoplication techniques, an endoscopic radiofrequency energy delivery technique, and 2 minimally invasive surgical procedures. These alternative techniques have been extensively evaluated; however, there are limitations to published studies, including arbitrary definitions of success, variable efficacy measurements, deficient reporting tools, inconsistent study designs, inconsistent lengths of follow-up postintervention, and lack of comparison data across techniques. Although all of the techniques appear to be safe, the endoscopic techniques lack demonstrable reflux control and show variable symptom improvement and variable decreases in proton pump inhibitor use. The surgical techniques are more robust, with evidence for adequate reflux control, symptom improvement, and decreased proton pump inhibitor use; however, these techniques are more difficult to perform and are more intrusive. Additionally, these alternative techniques have only been studied in patients with relatively normal anatomy. The field of gastroesophageal reflux disease treatment is in need of consistent definitions of efficacy, standardized study design and outcome measurements, and improved reporting

    Gastroesophageal reflux disease (GERD) has been related with certain psychological dimensions. The influence of mood, emotional intelligence, and perceived quality of life on clinical symptoms and outcome of antireflux surgery was evaluated in GERD patients with and without hiatal hernia. The study included 61 patients who were diagnosed with GERD between 2003 and 2008: 16 of them without hiatal hernia (group A) and 45 of them with hiatal hernia (group B). All of these patients had undergone laparoscopic antireflux surgery. Patients were clinically examined and evaluated with the following instruments: Short Form (SF)-36 Health Survey, Gastrointestinal Quality of Life Index, Hospital Anxiety and Depression (HAD) Scale, and Trait Meta-Mood Scale (TMMS)-24. Proportions were compared by using the chi-squared test; averages were compared by using the Student's t-test (with Bonferroni's correction). In general, our patients intervened for GERD showed results lower than normal or close to the lower limit of normal in the administered tests. Patients in the group without hernia were younger (P < 0.001) and with lower American Society of Anaesthesiologists risk. They showed higher scores in the SF-36 dimensions: Physical Functioning, Physical Role and Emotional Role, and lower scores in the Social Role (P < 0.001). They showed lower scores in the Emotional dimension of Gastrointestinal Quality of Life Index (P = 0.0068) and worse results in the Hospital Anxiety and Depression subscales of Anxiety (P < 0.001) and Depression (not significant). Men in the group without hernia showed higher scores than men in the group with hernia in the TMMS subscales corresponding to Emotional Clarity and Emotional Repair (P < 0.001). Women in the group with hernia showed higher scores than women in the group without hernia regarding Emotional Clarity (P = 0.0012). GERD patients showed poor results in all the tests, and patients without hiatal hernia compared with patients with hernia showed

    We report on a 22-year-old man with dysphagia and repeated bolus impaction in the esophagus for 10 years. Bolus impactions were frequently mobilised using an endoscope. At endoscopy, esophagitis IV degrees was described. After treatment with omeprazol there was no improvement. The patient was submitted to our hospital for fundoplication. pH-metry demonstrated an increased reflux. At endoscopy of the esophagus, we found red stripes which did not show the typical appearance of erosions. Manometry and X-ray films of the esophagus did not reveal any pathological findings. In combination with anamnesis, symptoms, and endoscopy, the diagnosis of eosinophilic esophagitis was documented by histology. After administration of oral corticosteroids a rapid improvement of the clinical symptoms was observed. The diagnosis of eosinophilic esophagitis should be kept in mind in patients with chronic symptoms of gastroesophageal reflux persisting despite medical therapy, pathological pH-metry and repeated bolus impactions.

    Introduction The gastroesophageal reflux disease is a common condition in the western world but less than half of patients present endoscopic abnormalities, making a standard procedure unsuitable for diagnosis. High definition endoscopy coupled with narrow band imaging has shown potential for differentiation of lesions and possible biopsy, allowing early diagnosis and treatment. Methods This review describes the principles of biotic and their influence in obtaining images with better definition of the vessels in the mucosa, through the narrow band imaging. Selected papers using it in patients with reflux disease and Barrett's esophagus are analyzed in several ways, highlighting the findings and limitations. Conclusion The meaning of the narrow band imaging in the endoscopic diagnosis of reflux disease will be defined by large scale studies, with different categories of patients, including assessment of symptoms and response to treatment.

    Background—The abnormally high postprandial rate of transient lower oesophageal sphincter relaxations seen in patients with reflux disease may be related to altered proximal gastric motor function. Heightened visceral sensitivity may also contribute to reporting of symptoms in these patients. 
Aims—To assess motor function of the proximal stomach and visceral perception in reflux disease with a barostat. 
Methods—Fasting and postprandial proximal gastric motility, sensation, and symptoms were measured in nine patients with reflux disease and nine healthy subjects. Gastric emptying of solids and liquids was assessed in six of the patients on a different day (and compared to historical controls). 
Results—Minimal distending pressure and gastric compliance were similar in the two groups, whereas the patients experienced fullness at lower pressures (p<0.05) and discomfort at lower balloon volumes (p<0.005) during isobaric and isovolumetric distensions respectively. Maximal gastric relaxation induced by the meal was similar in the two groups. Late after the meal, however, proximal gastric tone was lower (p<0.01) and the score for fullness higher (p<0.01) in the reflux patients, in whom the retention of both solids and liquids in the proximal stomach was greater (p<0.05). 
Conclusions—Reflux disease is associated with delayed recovery of proximal gastric tone after a meal and increased visceral sensitivity. The former may contribute to the increased prevalence of reflux during transient lower oesophageal sphincter relaxations and the delay in emptying from the proximal stomach, whereas both may contribute to symptom reporting.

    The mass-spectra of proteome of blood serum from healthy children and children with gastroesophageal reflux disease were received. The technology platform including direct proteome mass-spectrometer profiling after pre-fractional rectification using magnetic particles MB WCX was applied. The significant differences in mass-spectra were established manifesting in detection of more mass-spectrometer peaks and higher indicators of their intensity and area in group of healthy children. The study detected 39 particular peptides and low-molecular proteins predominantly intrinsic to healthy or ill children. It was established that two peptides with molecular mass 925 and 909 Da. are registered only in healthy patients and have no traces in group ofpatients with gastroesophageal reflux disease. The peptide 1564 Da is detected only in blood of children with gastroesophageal reflux disease and totally is absent in healthy children. The research data permitted to reveal specific patterns (signatures) of low-molecular proteins and peptides specific for blood serum of healthy children and patients with gastroesophageal reflux disease. The results testify the availability of singularities in metabolism of low-molecular proteins and can be used as a basis for development of minimally invasive mass-spectrometer system for its diagnostic.

    Gastroesophageal reflux disease (GERD) affects 10% to 20% of the western world's population. Current treatment guidelines recommend proton pump inhibitors (PPIs) as first-line therapy. Although PPIs cause mild adverse reactions, they pose risks, particularly for older adults with comorbidities.

    Identified were characteristics of individuals with skin damage related to chronic venous disease. Patients with chronic venous disease (n = 164) were evaluated with duplex ultrasound imaging and were placed in classes 4, 5, and 6 according to the CEAP classification. Their findings were compared with 100 class 2 controls. The prevalence of deep venous thrombosis was higher in the study group (23.7%) versus controls (5.1%; P < .0001), as was the prevalence of deep, perforator, and combined patterns of disease (P < .0001, P < .0007, and P < .0001). The mean duration of disease in controls 2 was shorter compared with the study group (P = .0019). The prevalence of reflux and obstruction within the study group was higher than in controls (P = .0021). Skin changes accurately reflect severity of chronic venous disease. Superficial and perforator vein reflux is the major cause of disease.

    Systemic sclerosis is a complex disease due to the variety of clinical presentations, often superimposed on other conditions, related or not to the connective tissue. We report a 43-year-old Brazilian woman with limited systemic sclerosis and pulmonary symptoms secondary to gastroesophageal reflux disease, with a clinical presentation similar to a diffuse interstitial lung disease. Because of the frequency of interstitial lung injury due to systemic sclerosis, this was an important differential diagnosis, which could be excluded after optimized treatment of reflux disease, with clinical and radiological improvement. Clinical management of patients with collagen diseases requires clinician skills to identify the natural history and understand its nuances. This is a common situation in clinical practice, but with a few discussions in international literature. PMID:26885429

    Background/Aims To evaluate the effectiveness of pantoprazole magnesium (pantoprazole-Mg) 40 mg in the relief of esophageal and extra-esophageal symptoms of gastroesophageal reflux disease (GERD), particularly night-time symptoms. Methods Patients (aged 18-50 years) with 3-month history of heartburn and/or acid regurgitation plus at least one other symptom in the last week were enrolled in a nationwide, prospective and observational study in Mexico. Patients received pantoprazole-Mg 40 mg once daily during 4 weeks. Symptoms were assessed through a physician-administered structured interview and the patient-completed ReQuest in Practice™ questionnaire. Night-time GERD was defined as arousal from sleep during the night due to GERD-associated symptoms. Results Out of 4,343 patients included at basal visit, 3,665 were considered for the effectiveness per protocol analysis. At baseline, patients had a median of 8 GERD related symptoms. Patients with night-time GERD symptoms (42.7%) were more likely to have extra-esophageal symptoms (P < 0.001) than other GERD patients. Pantoprazole-Mg 40 mg once daily for 4 weeks improved a broad range of GERD-associated symptoms from baseline (80% reduction on physicians assessments; 68-77% reduction on ReQuest in Practice™ dimensions), including both day- and night-time GERD symptoms; improvements were the greatest for extra-esophageal symptoms in patients with night-time symptoms. Pantoprazole-Mg was well tolerated. Conclusions Pantoprazole-Mg 40 mg significantly improved a broad range of esophageal and extra-esophageal GERD related symptoms including sleep disturbances, as well as well-being, in patients with daytime or night-time GERD, making it a good option for patients with GERD, especially when extra-esophageal and night-time symptoms are present.

    2016-01-01

    Patients with gastroesophageal reflux disease (GERD) who are not satisfied with acid suppression therapy can benefit primarily from fundoplication, a surgical intervention. Fundoplication has been the standard surgical procedure for GERD. It is effective but is associated with adverse effects, resulting in a declining number of interventions, creating a need for alternative interventions that are effective, yet have a better adverse effect profile. One such alternative involves the application of electrical stimulation to the lower esophageal sphincter. A number of animal studies showed that such stimulation can increase resting lower esophageal sphincter pressure. An acute human study confirmed this effect, and was followed by two open-label studies, with a follow-up of up to 3 years. Results thus far show that the therapy is associated with a significant improvement in symptoms, a significant reduction in esophageal acid exposure, and a very good safety profile. This review will describe the evolution of electrical stimulation therapy for GERD, as well as the safety and efficacy of this intervention. PMID:26834494

    Background The association between obesity and gastroesophageal reflux disease has a high incidence and may be present in half of obese patients with surgical indication. Bariatric operations can also induce reflux alone - differently from BMI factors - and its mechanisms are dependent on the type of procedure performed. Objective To perform a literature review comparing the two procedures currently most used for surgical treatment of obesity and analyze their relationship with the advent of pre-existing reflux disease or its appearance only in postoperative period. Method The literature was reviewed in virtual database Medline/PubMed, SciELO, Lilacs, Embase and Cochrane crossing the following MeSH descriptors: gastric bypass AND / OR anastomosis, Roux-en-Y AND / OR gastroesophageal reflux AND / OR gastroenterostomy AND / OR gastrectomy AND / OR obesity AND / OR bariatric surgery AND / OR postoperative period. A total of 135 relevant references were considered but only 30 were used in this article. Also was added the experience of the authors of this article in handling these techniques on this field. Conclusion The structural changes caused by surgical technique in vertical gastrectomy shows greater commitment of antireflux mechanisms predisposing the induction of GERD postoperatively compared to the surgical technique performed in the gastrointestinal Bypass Roux-en-Y.

    Gastroesophageal reflux disease (GERD) is a chronic disorder of the upper gastrointestinal tract with global distribution. The incidence is on the increase in different parts of the world. In the last 30 to 40 years, research findings have given rise to a more robust understanding of its pathophysiology, clinical presentation, and management. The current definition of GERD (The Montreal definition, 2006) is not only symptom-based and patient-driven, but also encompasses esophageal and extraesophageal manifestations of the disease. The implication is that the disease can be confidently diagnosed based on symptoms alone. Nonerosive reflux disease (NERD) remains the predominant form of GERD. Current thinking is that NERD and erosive reflux disease (ERD) are distinct phenotypes of GERD rather than the old concept which regarded them as components of a disease spectrum. Non erosive reflux disease is a very heterogeneous group with significant overlap with other functional gastrointestinal disorders. There is no gold standard for the diagnosis of GERD. Esophageal pH monitoring and intraluminal impedance monitoring have thrown some light on the heterogeneity of NERD. A substantial proportion of GERD patients continue to have symptoms despite optimal PPI therapy, and this has necessitated research into the development of new drugs. Several safety concerns have been raised about chronic use of proton pump inhibitors but these are yet to be substantiated in controlled studies. The debate about efficacy of long-term medical treatment compared to surgery continues, however, recent data indicate that modern surgical techniques and long-term PPI therapy have comparable efficacy. These and other issues are subjects of further research. PMID:22844607

    Background/Aims Different non-invasive diagnostics strategies have been used to assess patients with gastroesophageal reflux. Gastroesophageal reflux disease (GERD) questionnaire (GerdQ) is a 6-item, easy to use questionnaire that was developed primarily as a diagnostic tool for GERD in primary care. Our aim was to validate and assess diagnostic utility of GerdQ questionnaire in Mexican patients in the primary care setting. Methods The study was performed in 3 phases: (1) a questionnaire translation and comprehension study (n = 20), (2) are a reproducibility and validation study (50 patients and 50 controls) and (3) a study to assess the clinical utility in 252 subjects with GERD symptoms. Diagnostic accuracy was calculated using endoscopy and/or pH-metry as the gold standard. Results Internal consistency measured by the Cronbach’s α coefficient was 0.81 for patients and 0.90 for healthy controls, with a mixed coefficient of 0.93. Reproducibility for GerdQ was very good and its discriminating validity was 88%. Most of the patients with erosive reflux and non-erosive reflux with abnormal pH-metry had scores > 8, meanwhile most of the patients with functional heartburn and hypersensitive esophagus had < 8. Sensitivity, specificity and positive predictive value of GerdQ com -pared to the gold standard were 72%, 72% and 87%, respectively. Conclusions In Mexico, the GerdQ questionnaire Spanish validated version is useful for GERD diagnosis in the primary care setting. PMID:25273118

    The objective of this study is to determine the efficacy of adding a prokinetic agent to proton pump inhibitors (PPI) for the treatment of laryngopharyngeal reflux (LPR) disease. A prospective, randomized open trial comparing lansoprazole plus itopride to lansoprazole single therapy was performed for 12 weeks. Sixty-four patients with a reflux finding score (RFS) >7 and a reflux symptom index (RSI) >13 were enrolled and received either lansoprazole 30 mg once daily with itopride 50 mg three times daily or lansoprazole 30 mg once daily for 12 weeks. RSI and RFS were completed at baseline, after 6 weeks, and after 12 weeks. During the treatment period, RSI and RFS were significantly improved compared with the pretreatment scores in both study groups. Reductions of total RSI and globus symptom were significantly higher in the lansoprazole plus itopride group compared to the lansoprazole group. In the RFS, however, there were no significant differences between the two groups. In conclusion, itopride in addition to PPI did not show any superior RFS improvement compared to PPI single therapy, but was helpful in speeding up relief of reflux symptoms in LPR patients. Thus, itopride may be considered as the secondary additive agent in the PPI treatment of LPR patients.

    Thirty-six (36) patients with symptomatic gastroesophageal reflux were studied. Symptoms of heartburn, regurgitation, and dysphagia were scored as to their severity and compared to quantitative tests of gastroesophageal reflux. Patients were studied with the acid reflux test, fiberoptic endoscopy, exophageal mucosal biopsy with a pinch forceps, esophageal manometry, and radioisotopic gastroesophgeal scintigraphy. Symptoms were scored according to an arbitrary grading system as mild, moderate, or severe. There were significant correlations between symptoms scores and both the degree of endoscopic esophagitis and the gastroesophageal reflux indices as measured by the radioisotopic scintiscan, but not with the degree of histologic esophagitis or lower esophageal sphincter pressure. Review of the findings suggest the following profile for patients who might require antireflux surgery: severe symptoms; presence of endoscopic esophagitis; resting lower esophageal sphincter pressure below 10 mmHg; and gastroesophageal reflux index above 10%.

    The effect of a commercially available mixed amino acids solution, when given either intravenously or intragastrically, on lower esophageal sphincter (LES) pressure, frequency of transient LES relaxations (TLESRs) and gastroesophageal reflux (GER) was investigated in six healthy volunteers. LES pressure and esophageal pH were simultaneously recorded on three separate occasions 1 hr before (basal) and 3 hr during intravenous or intragastric infusion of amino acids (250 mg protein/kg/hr) or saline (control). No significant changes in LES pressure were seen in the control experiment. Intravenous amino acids caused a rapid and sustained (P < 0.01) decrease in LES pressure whereas intragastric amino acids decreased LES pressure only gradually and temporarily (P < 0.01). In the three experiments no significant differences were observed in TLESR frequency, the number of GER episodes, the mechanism of reflux, or duration of acid exposure. In healthy subjects both intragastric and, especially, intravenous infusion of amino acids significantly decrease LES pressure but do not affect the frequency of TLESRs or GER episodes during a continuous liquid gastric load.

    Gastroesophageal reflux is a common disease. Its chronic course, even if mild, is sometimes complicated by erosive oesophagitis. Drug therapy acts against gastric acidity and motility disorders. Treatment of gastroesophageal reflux disease has three aims: improvement of symptoms and quality of life, healing erosive lesions and prevention of symptomatic and endoscopic relapses. Non-drug measures are always useful, even if their efficacy is not well established. Initial therapy of a symptomatic reflux or mild oesophagitis is most of the time effective (antacids, prokinetics, H2 receptor antagonists). Proton-pump inhibitors are also effective in healing and preventing severe oesophagitis. Questions about long-term treatment adverse events with powerful acid inhibitors, such as hypergastrinemia and the risk of gastric carcinoid tumours seem to be resolved. Studies are requested to define the optimal long-term maintenance treatment with cisapride, H2 receptor antagonists or proton-pump inhibitors at low doses in prevention of symptomatic and mild oesophagitis relapses.

    Adenoid hypertrophy is a disease that mostly occurs among children of 3-5 years old. It is caused by repeated inflammation and infection of nasopharynx and its adjoin parts, or the adenoid itself, which will finally leads to pathological hyperplasia of adenoid. With so much information we have acquired about this disease, its specific mechanism remains unknown. In recent years, some researches have indicated that adenoid hypertrophy may have something to do with extra-gastroesophageal reflux, in which pepsin plays a very important role, and pepsin will do a series of pathological damages to the upper airway as it reaches the upper respiratory tract. Based on relative domestic and foreign literature, this paper attempts to make a review about the relationship between gastroesophageal reflux and adenoid hypertrophy.

  5. The role of dexlansoprazole modified-release in the management of gastroesophageal reflux disease

    Dexlansoprazole modified-release (MR) is the R-enantiomer of lansoprazole and is currently the only proton-pump inhibitor (PPI) with a novel dual delayed release (DDR) formulation. Overall, dexlansoprazole MR demonstrates a similar safety and side-effect profile as lansoprazole. Dexlansoprazole MR has been shown to be highly efficacious in healing erosive esophagitis, maintaining healed esophageal mucosa in patients with erosive esophagitis and controlling symptoms of patients with nonerosive reflux disease (NERD). Recent studies have also demonstrated that dexlansoprazole MR is highly effective in improving nocturnal heartburn, gastroesophageal reflux disease (GERD) related sleep disturbances and bothersome regurgitation. Dexlansoprazole MR is well tolerated and can be taken without regard to food. PMID:28203282

    Gastroesophageal reflux and bronchial asthma are frequently encountered comorbidities that maintain an ambivalent relationship, generating a vicious circle where gastroesophageal reflux increases asthmatic symptoms or precipitates bronchial asthma and asthma can trigger or worsen gastroesophageal reflux disease. Pathogenetic mechanisms of these interrelation are imperfectly understood, despite intense concerns of specialists in both areas. There have been incriminated: eso-bronchial constrictor vagal mediated reflexes, bronchial hyperreactivity, neurogenic inflammation induced by hydrochloric acid penetration in the oesofagus, airways hydrochloric acid microaspiration with asthmatic trigger effects, increased bronchial resistance or increased immune response to antigens. Bronchial obstruction and some antiasthmatic medication can decrease lower esophageal sphincter pressure and thus triggering or aggravating gastroesophageal reflux. The diagnosis of the gastroesophageal reflux in asthmatics involves a careful clinical exam, digestive functional test (up to 24 hours monitoring esophageal pH) and esogastroscopy. Gastroesophageal reflux treatment in asthmatic patients claims elimination of both disease risk factors, diet, proton-pump inhibitors.

    This study investigated the effectiveness of diaphragm biofeedback training (DBT) for patients with gastroesophageal reflux disease (GERD). A total of 40 patients with GERD treated at the Peking Union Medical College Hospital between September 2004 and July 2006 were randomized to receive DBT and rabeprazole proton pump inhibitor (PPI) or rabeprazole alone. The DBT + rabeprazole group received DBT during the 8-week initial treatment; the rabeprazole group did not. During the 6-month follow up, all patients took acid suppression according to their reflux symptoms, and the patients in the DBT + rabeprazole group were required to continue DBT. The primary outcome (used for power analysis) was the amount of acid suppression used at 6 months. Secondary outcomes were reflux symptoms, health-related quality of life (HRQL), and esophageal motility differences after the 8-week treatment compared with baseline. Acid suppression usage significantly decreased in the DBT + rabeprazole group compared with the rabeprazole group at 6 months (P < 0.05). At 8 weeks, reflux symptoms and GERD-HRQL were significantly improved in both groups (P < 0.05), without difference between them. Crural diaphragm tension (CDT) and gastroesophageal junction pressure (GEJP) significantly increased in the DBT + rabeprazole group (P < 0.05), but without change in lower esophageal sphincter (LES) pressure. There was no significant change in CDT, GEJP, and LES pressure compared with baseline in the rabeprazole group. In conclusion, long-term DBT could reduce acid suppression usage by enhancing the anti-reflux barrier, providing a non-pharmacological maintenance therapy and reducing medical costs for patients with GERD.

    AIM To compare long-term occurrence of gastroesophageal reflux disease (GERD) between two different types of peroral endoscopic myotomy (POEM) for achalasia. METHODS We included all patients with achalasia who underwent POEM at our hospital from August 2011 to October 2012 and had complete GERD evaluation with ≥ 3 years of follow-up. They were divided into circular or full-thickness myotomy groups according to the depth of myotomy. Demographics, Eckardt score, manometry results, 24-h pH monitoring, and GERD symptoms were recorded and compared between the two groups. RESULTS We studied 56 patients (32 circular myotomy and 24 full-thickness myotomy) with complete GERD evaluation. There was no significant difference between the two groups in terms of treatment success (defined as Eckardt score ≤ 3), postoperative Eckardt score, mean basal lower esophageal sphincter pressure, and 4-s integrated relaxation pressure (4sIRP). Postoperative abnormal esophageal acid exposure was found in 25 patients (44.6%). A total of 13 patients (23.2%) had GERD symptoms and 12 had esophagitis (21.4%). Clinically relevant GERD (abnormal esophageal acid exposure associated with GERD symptoms and/or esophagitis) was diagnosed in 13 patients (23.2%). Multivariate analysis revealed that full-thickness myotomy and low level of postoperative 4sIRP were predictive factors for clinically relevant GERD. CONCLUSION Efficacy and manometry are comparable between achalasia patients treated with circular or full-thickness myotomy. But patients with full-thickness myotomy and low postoperative 4sIRP have more GERD. PMID:27895430

    Background Refractory gastroesophageal reflux disease (GERD) may deteriorate patient quality of life (QOL) despite proton pump inhibitor (PPI) therapy. Material/Methods Nineteen Japanese institutions were surveyed to determine the clinical characteristics and QOL of patients with refractory GERD. Those patients treated with a conventional PPI were switched to 20 mg esomeprazole for 4 weeks. Symptoms and QOL were assessed using Global Overall Symptom and Gastrointestinal Symptom Rating Scale (GSRS) questionnaires at baseline and at 2 and/or 4 weeks of esomeprazole treatment. Results Of 120 patients who completed the survey, 58 (48.3%) had refractory GERD. Of these, 69.0% were aged ≥65 years, 79.3% were prescribed a PPI at a standard or high dose, and 22.4% were prescribed a PPI together with another drug. After switching to esomeprazole, patients reported significant improvements in heartburn, acid regurgitation, and excessive belching at 2 weeks using a symptom diary, as well as the total score, reflux, abdominal pain, and indigestion, which were assessed using the GSRS at 4 weeks. Conclusions About half of Japanese patients with GERD may be refractory to conventional PPIs. Their reflux-related symptoms are often severe and may impair QOL. Switching to esomeprazole could be used to improve their symptoms and QOL. PMID:26719012

    AIM: To investigate usefulness of adherence to gastro-esophageal reflux disease (GERD) guideline established by the Spanish Association of Gastroenterology. METHODS: Prospective, observational and multicentre study of 301 patients with typical symptoms of GERD who should be managed in accordance with guidelines and were attended by gastroenterologists in daily practice. Patients (aged > 18 years) were eligible for inclusion if they had typical symptoms of GERD (heartburn and/or acid regurgitation) as the major complaint in the presence or absence of accompanying atypical symptoms, such as dyspeptic symptoms and/or supraesophageal symptoms. Diagnostic and therapeutic decisions should be made based on specific recommendations of the Spanish clinical practice guideline for GERD which is a widely disseminated and well known instrument among Spanish in digestive disease specialists. RESULTS: Endoscopy was indicated in 123 (41%) patients: 50 with alarm symptoms, 32 with age > 50 years without alarm symptom. Seventy-two patients (58.5%) had esophagitis (grade A, 23, grade B, 28, grade C, 18, grade D, 3). In the presence of alarm symptoms, endoscopy was indicated consistently with recommendations in 98% of cases. However, in the absence of alarm symptoms, endoscopy was indicated in 33% of patients > 50 years (not recommended by the guideline). Adherence for proton pump inhibitors (PPIs) therapy was 80%, but doses prescribed were lower (half) in 5% of cases and higher (double) in 15%. Adherence regarding duration of PPI therapy was 69%; duration was shorter than recommended in 1% (4 wk in esophagitis grades C-D) or longer in 30% (8 wk in esophagitis grades A-B or in patients without endoscopy). Treatment response was higher when PPI doses were consistent with guidelines, although differences were not significant (95% vs 85%). CONCLUSION: GERD guideline compliance was quite good although endoscopy was over indicated in patients > 50 years without alarm symptoms; PPIs were

    The current work assessed a pharmaceutical dosage form of Myrtus communis L. (myrtle) in reflux disease compared with omeprazol via a 6-week double-blind randomized controlled clinical trial. Forty-five participants were assigned randomly to 3 groups as A (myrtle berries freeze-dried aqueous extract, 1000 mg/d), B (omeprazol capsules, 20 mg/d), and C (A and B). The assessment at the beginning and the end of the study was done by using a standardized questionnaire of frequency scale for the symptoms of gastroesophageal reflux disease (FSSG). In all groups, both reflux and dyspeptic scores significantly decreased in comparison with the respective baselines. Concerning each group, significant changes were found in FSSG, dysmotility-like symptoms and acid reflux related scores. No significant differences were observed between all groups in final FSSG total scores (FSSG2). Further studies with more precise design and larger sample size may lead to a better outcome to suggest the preparation as an alternative intervention.

    Esophageal reflux of gastric contents causes esophageal mucosal damage and inflammation. Recent studies show that oxygen-derived free radicals mediate mucosal damage in reflux esophagitis (RE). Chlorogenic acid (CGA), an ester of caffeic acid and quinic acid, is one of the most abundant polyphenols in the human diet and possesses anti-inflammatory, antibacterial and anti-oxidant activities. In this context, we investigated the effects of CGA against experimental RE in rats. RE was produced by ligating the transitional region between the forestomach and the glandular portion and covering the duodenum near the pylorus ring with a small piece of catheter. CGA (10, 30 and 100 mg/kg) and omeprazole (positive control, 10 mg/kg) were administered orally 48 h after the RE operation for 12 days. CGA reduced the severity of esophageal lesions, and this beneficial effect was confirmed by histopathological observations. CGA reduced esophageal lipid peroxidation and increased the reduced glutathione/oxidized glutathione ratio. CGA attenuated increases in the serum level of tumor necrosis factor-α, and expressions of inducible nitric oxide synthase and cyclooxygenase-2 protein. CGA alleviates RE-induced mucosal injury, and this protection is associated with reduced oxidative stress and the anti-inflammatory properties of CGA. PMID:25414772

    Transnasal ultrathin esophagogastroduodenoscopy (N-EGD) with less gagging reflexes under non-sedation is likely suitable for the diagnosis of gastroesophageal reflux disease (GERD), however, N-EGD might have drawbacks, including its low image resolution. Limited information is available regarding the diagnosability of N-EGD for GERD. We compared the utility and gagging reflexes of three different endoscopies, including N-EGD, ultrathin transoral EGD (UTO-EGD) and conventional oral EGD (CO-EGD), in the diagnosis of GERD. We performed screening endoscopy in 1580 patients (N-EGD n=727, UTO-EGD n=599, CO-EGD n=254) and compared the frequency distributions of the severity of reflux esophagitis, hiatus hernia, and Barrett's epithelium to estimate the diagnostic performance of each endoscopy. We also analyzed patients' tolerability of endoscopy by the subjective evaluation of gagging reflexes. In the diagnosis of reflux esophagitis and Barrett's epithelium, there was no significant difference in the frequency distributions of the severity of the diseases among three EGDs. However, the incidence of Barrett's epithelium was higher than that in the previous nationwide survey of GERD in Japan. The evaluated size of hiatus hernia was smaller in N-EGD than in two other peroral endoscopies. The size of hiatus hernia correlated significantly with severity of gagging reflexes that was also lowest when diagnosed with N-EGD. N-EGD had an equivalent performance in the diagnosis of reflux esophagitis and Barrett's epithelium compared with CO-EGD. Enlargement of hiatus hernia induced by gagging reflexes was minimal in N-EGD, resulting in its better performance in the diagnosis of Barrett's epithelium.

    Background—Belching has been proposed as a major mechanism underlying acid gastro-oesophageal reflux in normal subjects. However, the presence of oesophageal gas has not been measured directly but only inferred from manometry. 
Aims—To investigate, using intraluminal electrical impedance, the patterns of gas and liquid reflux during transient lower oesophageal sphincter (LOS) relaxations, the main mechanism of acid reflux in normal subjects. 
Methods—Impedance changes associated with the passage of gas were studied in vitro, and in vivo in cats. Oesophageal manometry, pH, and intraluminal electrical impedance measurements were performed in 11 normal subjects after a meal. 
Results—Gas reflux caused a sudden increase in impedance that propagated rapidly to the proximal oesophagus whereas liquid reflux induced a retrogressively propagated fall in impedance. Impedance showed gas or liquid reflux during most (102/141) transient LOS relaxations. When acid reflux occurred, impedance showed evidence of intraoesophageal retrograde flow of liquid in the majority (78%) of events. Evidence of gas retroflow was found in almost half (47%) of acid reflux episodes. When present together, however, liquid preceded gas on 44% of occasions. Overall, gas reflux occurred as the initial event in only 25% of acid reflux episodes. 
Conclusions—These findings suggest that in upright normal subjects, although belching can precipitate acid reflux, most acid reflux occurs as a primary event.

    Objective: To compare the efficacy and safety of rabeprazole and esomeprazole in mild-to-moderate erosive gastroesophageal reflux disease (GERD). Materials and Methods: A randomized, single-blinded, outdoor-based clinical study was conducted on 60 patients of mild-to-moderate erosive GERD. After baseline clinical assessment and investigations, rabeprazole (40 mg) was prescribed to 30 patients and esomeprazole (40 mg) to another 30 patients for 4 weeks. The efficacy variables were change in GERD symptom scoring, endoscopic findings, and Quality of Life in Reflux and Dyspepsia (QOLRAD) scoring over 4 weeks. Result: Heartburn, acid regurgitation, and overall GERD symptom scoring (P = 0.01) were significantly decreased with rabeprazole in comparison to esomeprazole. The comparative study of all five domains of the QOLARD questionnaire including overall scoring revealed a statistically significant improvement in the rabeprazole group. Endoscopic findings in the rabeprazole group showed an absolute improvement of 30% and relative improvement of 55% over esomeprazole. Both the drugs were well tolerated having no significant difference in the incidence of adverse effects. Conclusion: Rabeprazole (40 mg) is a better choice for mild-to-moderate GERD compared with esomeprazole (40 mg) because of its better efficacy and safety profile. PMID:21897706

    The relationship between esophageal motor abnormalities and GERD has been widely studied. The purpose of this study was to identify the prevalence of ineffective esophageal motility (IEM) in patients with GERD. In addition, we also evaluated esophageal acid exposure, acid clearance, and endoscopic esophagitis in GERD patients with IEM. Of 89 patients enrolled in this study, 47 (52.8%) were found to have nonspecific esophageal motility disorder (NEMD). Forty-four of the 47 (93.6%) patients with NEMD met the diagnostic criteria for IEM. The overall incidence of IEM in GERD patients was 49.4%. Patients with IEM had significant increases in upright and recumbent mean fraction of time pH < 4 (6.70% and 4.38%) and mean recumbent esophageal acid clearance (12.45 min/reflux) when compared to those with other motility findings. Seventeen of the 44 (39%) IEM patients did not have endoscopic esophagitis. On the other hand, 26 of the 39 (67%) patients with normal manometry had endoscopic esophagitis. We concluded that not only is the prevalence of IEM high in GERD, but also that IEM patients have more recumbent gastroesophageal reflux and delayed acid clearance. Combined with endoscopic findings, we propose that IEM can be viewed as a specific entity of primary esophageal motility disorder in patients with GERD.

    Background/Aims The post-reflux swallow-induced peristaltic wave (PSPW) index and esophageal baseline impedance (BI) are novel impedance parameters used to evaluate esophageal chemical clearance and mucosal integrity. However, their relationship with reflux symptoms is not known. We aim to evaluate the correlations of PSPW index and esophageal BI with gastroesophageal reflux disease (GERD) symptoms. Methods We performed a retrospective review of multichannel intraluminal impedance and pH (MII-pH) tracings in patients with suspected GERD. Reflux symptoms were also analyzed from checklists using ordinal scales. The PSPW index and esophageal BIs in 6 spots (z1–z6) were measured. Bivariate (Spearman) correlation was used to analyze the relationship between the PSPW index or esophageal BI, and the degree of GERD symptoms measured. Results The MII-pH records of 143 patients were analyzed. The PSPW index was significantly lower in patients who had heartburn and negatively correlated with the degree of heartburn (r = −0.186, P < 0.05). On the contrary, the PSPW index was not significantly correlated with the degree of dysphagia (r = −0.013, P = 0.874). Distal esophageal BI was not significantly correlated with heartburn, but negatively correlated with the degree of dysphagia (z3: r = −0.328, z4: r = −0.361, z5: r = −0.316, z6: r = −0.273; P < 0.05). Conclusions These findings suggest that delayed chemical clearance of the esophagus may induce heartburn, but that it is not related to dysphagia. However, a lack of esophageal mucosal integrity may be related to dysphagia. PMID:28044052

    Background/Aims Proton pump inhibitors (PPIs) are widely used in the treatment of gastroesophageal reflux disease (GERD). However, some patients fail to respond to PPI therapy. We investigated the efficacy of response to PPI therapy in patients with GERD symptoms. Methods A total of 179 subjects with GERD symptoms were prospectively enrolled and diagnosed with non-erosive reflux disease (NERD, n = 100) and erosive reflux disease (n = 79) by gastroscopy and Bernstein test and/or 24-hour esophageal pH testing. Subjects then received a standard dose of daily PPI therapy for at least 4 weeks. PPI therapy response was evaluated using questionnaires including questions about demographics, GERD symptoms, GERD impact scale, Epworth sleepiness scale, Pittsburgh sleep quality index (PSQI), hospital anxiety and depression scale, and abbreviated version of the World Health Organization quality of life scale. Results The rates of complete (≥ 80%), satisfactory (≥ 50%), partial (< 50%), and refractory response in the 179 participants were 41.3%, 30.2%, 18.4%, and 10.1%, respectively. Thus, overall response rate (complete and satisfactory responses) was 71.5%. Multivariate analysis showed body mass index < 23 kg/m2 (OR, 2.20; 95% CI, 1.12–4.34), higher total PSQI score (OR, 1.20; 95% CI, 1.05–1.35), history of psychotherapy or neuropsychiatric medication (OR, 2.44; 95% CI, 1.23–4.85), and NERD (OR, 3.30; 95% CI, 1.54–7.11) were associated with poor response to PPI therapy. Conclusions Psychological factors, sleep dysfunction, body mass index < 23 kg/m2, and NERD seem to be the major factors that lead to a poor response to PPI treatment in patients with GERD symptoms.

    In patients with gastroesophageal reflux disease (GERD) and erosive esophagitis, treatment with proton pump inhibitors (PPIs) is highly effective. However, in some patients, especially those with non-erosive reflux disease or atypical GERD symptoms, acid suppressive therapy with PPIs is not as successful. Alginates are medications that work through an alternative mechanism by displacing the post-prandial gastric acid pocket. We performed a systematic review and meta-analysis to examine the benefit of alginate-containing compounds in the treatment of patients with symptoms of GERD.PubMed/MEDLINE, Embase and the Cochrane library electronic databases were searched through October 2015 for randomized controlled trials comparing alginate-containing compounds to placebo, antacids, histamine-2 receptor antagonists (H2RAs) or PPIs for the treatment of GERD symptoms. Additional studies were identified through bibliography review. Non-English studies and those with pediatric patients were excluded. Meta-analyses were performed using random-effects models to calculate odds ratios (OR). Heterogeneity between studies was estimated using the I(2) statistic. Analyses were stratified by type of comparator. The search strategy yielded 665 studies and 15 (2.3%) met inclusion criteria. Fourteen were included in the meta-analysis (N = 2095 subjects). Alginate-based therapies increased the odds of resolution of GERD symptoms when compared to placebo or antacids (OR: 4.42; 95% CI 2.45-7.97) with a moderate degree of heterogeneity between studies (I(2)  = 71%, P = .001). Compared to PPIs or H2RAs, alginates appear less effective but the pooled estimate was not statistically significant (OR: 0.58; 95% CI 0.27-1.22). Alginates are more effective than placebo or antacids for treating GERD symptoms.

    Background Gastro-esophageal reflux disease (GERD) is a common disease. It impairs health related quality of life (HRQL). However, the impact on utility scores and work productivity in patients with moderate to severe GERD is not well known. Methods We analyzed data from 217 patients with moderate to severe GERD (mean age 50, SD 13.7) across 17 Canadian centers. Patients completed three utility instruments – the standard gamble (SG), the feeling thermometer (FT), and the Health Utilities Index 3 (HUI 3) – and several HRQL instruments, including Quality of Life in Reflux and Dyspepsia (QOLRAD) and the Medical Outcomes Short Form-36 (SF-36). All patients received a proton pump inhibitor, esomeprazole 40 mg daily, for four to six weeks. Results The mean scores on a scale from 0 (dead) to 1 (full health) obtained for the FT, SG, and HUI 3 were 0.67 (95% CI, 0.64 to 0.70), 0.76 (95% CI, 0.75 to 0.80), and 0.80 (95% CI, 0.77 to 0.82) respectively. The mean scores on the SF-36 were lower than the previously reported Canadian and US general population mean scores and work productivity was impaired. Conclusion GERD has significant impact on utility scores, HRQL, and work productivity in patients with moderate to severe disease. Furthermore, the FT and HUI 3 provide more valid measurements of HRQL in GERD than the SG. After treatment with esomeprazole, patients showed improved HRQL. PMID:16004616

    Background Evidence is increasingly convincing that lung transplantation is a risk factor of gastroesophageal reflux disease (GERD). However, it is still not known if the type of lung transplant (unilateral, bilateral, or retransplant) plays a role in the pathogenesis of GERD. Study Design The records of 61 lung transplant patients who underwent esophageal function tests between September 2008 and May 2010, were retrospectively reviewed. These patients were divided into 3 groups based on the type of lung transplant they received: unilateral (n=25); bilateral (n=30), and retransplant (n=6). Among these groups we compared: (1) the demographic characteristics (eg, sex, age, race, and body mass index); (2) the presence of Barrett esophagus, delayed gastric emptying, and hiatal hernia; and (3) the esophageal manometric and pH-metric profile. Results Distal and proximal reflux were more prevalent in patients with bilateral transplant or retransplant and less prevalent in patients after unilateral transplant, regardless of the cause of their lung disease. The prevalence of hiatal hernia, Barrett esophagus, and the manometric profile were similar in all groups of patients. Conclusions Although our data show a discrepancy in prevalence of GERD in patients with different types of lung transplantation, we cannot determine the exact cause for these findings from this study. We speculate that the extent of dissection during the transplant places the patients at risk for GERD. On the basis of the results of this study, a higher level of suspicion of GERD should be held in patients after bilateral or retransplantation. PMID:22318059

    Background and aim. Patients with disabilities have a higher prevalence of caries and dental erosions than general population. This particularity may be assessed by the study of microcrystallization of saliva. We investigated the oral liquid microcrystallization in children with gastroesophageal reflux disease (GERD), a condition associated with dental erosions. Material and methods. 54 children have been clinically examined: 27 children suffering from GERD with ages between 13 and 15, were included in the study group, and 27 healthy children - the control group. The study of crystallographic changes of the oral liquid was performed using the method developed by Shatohina, Razumov SN, Shabalin VN (2006) with the scanning electron microscope VEGA TESCAN TS 5130 MM. Results The degree of microcrystalization of the oral liquid in children with GERD was considerably reduced, (1.73±0.11 points) and was lower than in children in the control group (3.22±0.16 points) (p<0.01, RR=2). The degree of microcrystallization of oral liquid in children with GERD was 1.86 times lower than in healthy children. This was correlated with the duration of gastroesophageal reflux. Conclusion The study of structural particularities of dehydrated droplet of oral liquid in children with GERD has elucidated a number of markers of the changes produced in the oral cavity. These can be used in the screening research in prevention of caries and dental erosions. PMID:26528035

    Belching is a common symptom of gastroesophageal reflux disease. If the symptoms are not relieved after anti-reflux treatment, another etiology should be considered. Here, we report a case of a 43-year-old man who presented with belching, regurgitation, chest tightness and dyspnea for 18 mo, which became gradually more severe. Gastroscopic examination suggested superficial gastritis. Twenty-four-hour esophageal pH monitoring showed that the Demeester score was 11.4, in the normal range. High-resolution manometry showed that integrated relaxation pressure and intrabolus pressure were higher than normal (20 mmHg and 22.4 mmHg, respectively), indicating gastroesophageal junction outflow tract obstruction. Pulmonary function test showed severe obstructive ventilation dysfunction [forced expiratory volume in 1 second (FEV1)/forced vital capacity 32%, FEV1 was 1.21 L, occupying 35% predicted value after salbuterol inhalation], and positive bronchial dilation test (∆FEV1 260 mL, ∆FEV1% 27%). Skin prick test showed Dermatophagoides farinae (++), house dust mite (++++), and shrimp protein (++). Fractional exhaled nitric oxide measurement was 76 ppb. All the symptoms were alleviated completely and pulmonary function increased after combination therapy with corticosteroids and long-acting β2-agonist. Bronchial asthma was eventually diagnosed by laboratory tests and the effect of anti-asthmatic treatment, therefore, physicians, especially the Gastrointestinal physicians, should pay attention to the belching symptoms of asthma.

    AIM: To compare the clinical efficacy of the second-generation H2RA lafutidine with that of lansoprazole in Japanese patients with mild gastroesophageal reflux disease (GERD). METHODS: Patients with symptoms of GERD and a diagnosis of grade A reflux esophagitis (according to the Los Angeles classification) were randomized to receive lafutidine (10 mg, twice daily) or lansoprazole (30 mg, once daily) for an initial 8 wk, followed by maintenance treatment comprising half-doses of the assigned drug for 24 wk. The primary endpoint was the frequency and severity of heartburn during initial and maintenance treatment. The secondary endpoints were the sum score of questions 2 and 3 in the Gastrointestinal Symptom Rating Scale (GSRS), and the satisfaction score. RESULTS: Between April 2012 and March 2013, a total of 53 patients were enrolled, of whom 24 and 29 received lafutidine and lansoprazole, respectively. After 8 wk, the frequency and severity of heartburn was significantly reduced in both groups. However, lafutidine was significantly inferior to lansoprazole with regard to the severity of heartburn during initial and maintenance treatment (P = 0.016). The sum score of questions 2 and 3 in the GSRS, and satisfaction scores were also significantly worse in the lafutidine group than the lansoprazole group (P = 0.0068 and P = 0.0048, respectively). CONCLUSION: The clinical efficacy of lafutidine was inferior to that of lansoprazole, even in Japanese patients with mild GERD. PMID:27340360

    Gastroesophageal reflux disease (GERD) is a disorder, which gastric content repeatedly reflux into the esophagus causing disturbing symptoms and/or complications. Various epidemiological studies show that there is regional difference on the aspect of prevalence and clinical manifestation. Regional data also demonstrates increased incidence of complications such as the Barret's Esophagus and adenocarcinoma. In response to the situation, the Asia-Pacific GERD experts, including Indonesia, had published a consensus on the management of GERD in 2004, which was subsequently revised in 2008. Advances in medical technology, especially on gastrointestinal endoscopy technique and other diagnostic instruments such as 24-hour pH-metry and manometry, have improved the capacity of management of GERD. On the other hand, we feel that adequate knowledge and skills of doctors, both for general physicians and specialists of internal medicine in our country are not well-distributed. Moreover, the availability of instruments for diagnostic and therapeutical supports differs from one region to the others. The Organizing Committee of Indonesian Society of Gastroenterology or Pengurus Besar Perkumpulan Gastroenterologi Indonesia (PB PGI) considers that it is important to revise the National Consensus on the Management of GERD in Indonesia 2004, which is expected to be the guideline of GERD management.

  6. Lifestyle measures in the management of gastro-oesophageal reflux disease: clinical and pathophysiological considerations

    Several lifestyle and dietary factors are commonly cited as risk factors for gastro-oesophageal reflux disease (GORD) and modification of these factors has been advocated as first-line measures for the management of GORD. We performed a systematic review of the literature from 2005 to the present relating to the effect of these factors and their modification on GORD symptoms, physiological parameters of reflux as well as endoscopic appearances. Conflicting results existed for the association between smoking, alcohol and various dietary factors in the development of GORD. These equivocal findings are partly due to methodology problems. There is recent good evidence that weight reduction and smoking cessation are beneficial in reducing GORD symptoms. Clinical and physiological studies also suggest that some physical measures as well as modification of meal size and timing can also be beneficial. However, there is limited evidence for the role of avoiding alcohol and certain dietary ingredients including carbonated drinks, caffeine, fat, spicy foods, chocolate and mint. PMID:25729556

    Many people with gastro-esophageal reflux symptoms do not consult a physician; therefore studies on gastro-esophageal reflux in general practice or in hospitals may not accurately describe the burden of gastro-esophageal reflux symptoms in the general population. The aim of this study was to assess the prevalence of gastro-esophageal reflux disease and its association with some life-style parameters in Rasht-Iran. A telephone survey was performed. Phone numbers was randomly collected from the telecommunication service center of Rasht. 1473 people (Mean age: 38.31 ± 13.09) were included in the study. People who didn’t answer the phone after three times or didn’t have consent to enter the study were excluded. Data were collected by an examiner using a GerdQ questionnaire. The validity and reliability of the questionnaire was tested by translation and retranslation and a pilot study was performed to assess its appropriateness. The prevalence of gastro-esophageal reflux was achieved 2.4% daily, 9.1% weekly and 11.3% monthly. Among the patients with gastro-esophageal reflux, 69.5% were female. There was a significant positive association between gastro-esophageal reflux prevalence and body mass index, smoking habits, eating salted or smoked foods, lying down immediately after the meal, taking certain drugs as non-steroidal anti-inflammatory drugs/Amino salicylic acid and the age group of 30-45 year old. Overall, the prevalence of the weekly gastro-esophageal reflux in the present survey was 9.1% which was less than other similar studies in Iran and some other countries. PMID:24046810

    The gastroesophageal reflux disease (GERD) is one of the main causes of dental erosion. The aim of this case presented is to describe the prosthetic rehabilitation of a patient with GERD after 4 years of followup. A 33-year-old male patient complained about tooth sensitivity. The lingual surface of the maxillary anterior teeth and the cusps of the upper and lower posterior teeth presented wear. It was suspected that the feeling of heartburn reported by the patient associated with the intake of sports supplements (isotonics) was causing gastroesophageal changes. The patient was referred to a gastroenterologist and was diagnosed with GERD. Dental treatment was performed with metal-free crowns and porcelain veneers after medical treatment of the disease. With the change in eating habits, the treatment of GERD and lithium disilicate ceramics provided excellent cosmetic results after 4 years and the patient reported satisfaction with the treatment.

    Gastroesophageal reflux disease (GERD) is a common condition among adults that can cause symptoms such as frequent heartburn, substernal chest pain, and regurgitation of food. During 2005-2014, a total of 137,081 active component service members had an incident (first-ever) diagnosis of GERD (incidence rate: 101.3 per 10,000 person-years). Incidence rates were higher than their respective counterparts among females, black and white non-Hispanics, service members in the Coast Guard and Air Force, officers, and those in healthcare occupations. Rates increased monotonically with increasing age groups. Most GERD cases (79.2%) were uncomplicated GERD; however, 20.8% were identified as having a symptom or complication linked to their GERD diagnosis. Lifestyle changes, medication, and prevention of serious complications should be emphasized among individuals diagnosed with GERD, particularly those at risk for severe disease.

    Gastroesophageal reflux disease (GERD) is one of the most common problems in clinical practice today. It is widely believed that functional and structural abnormalities of the gastroesophageal junction as well as an abnormal exposure to gastroduodenal contents are the main contributors to its pathogenesis. Novel findings of the inflammatory process in GERD suggest a far more complex process involving multifaceted inflammatory mechanisms. This review summarizes knowledge about the expression of inflammatory mediators in GERD and their potential cellular sources and provides an integrated concept of disease pathogenesis. In addition we evaluate the contribution of inflammatory mediators to well-known complications of GERD, namely motility abnormalities, fibrosis, and carcinogenesis. Novel findings regarding the pathophysiology of esophageal inflammation should enhance our understanding of GERD and its complications and provide new treatment insights.

    Gastroesophageal reflux disease is associated with impaired epithelial barrier function and abnormal expression of proteins forming cell-cell contacts by tight junctions and desmosomes in distal esophageal squamous mucosa. Although gastroesophageal reflux disease and Helicobacter pylori are both associated with chronic inflammation of the adjacent cardia mucosa, it is not known whether these lead to derangements of the desmosomal complexes. Here, we assessed the expression of 4 proteins (plakoglobin and desmoglein 1, 2, and 3) forming epithelial desmosomal complexes by quantitative reverse transcription polymerase chain reaction and immunohistochemistry in biopsies from 67 patients with gastroesophageal reflux disease and 23 gastroesophageal reflux disease-negative controls. Plakoglobin and desmoglein 2 were ubiquitously expressed in all samples, whereas desmoglein 1 and 3 were not expressed in cardia mucosa. Gastroesophageal reflux disease was specifically associated with elevated transcript levels of desmoglein 2 and plakoglobin. These were significantly increased from 2.0- to 2.7-fold in patients with gastroesophageal reflux disease compared with controls (P < .01), and significantly increased immunohistochemical scores for both proteins were observed (P < .05) as well. The combined presence of gastroesophageal reflux disease and Helicobacter pylori infection had no additional effect on desmosomal gene expression. Taken together, the up-regulation of plakoglobin and desmoglein 2 in cardia mucosa of patients with gastroesophageal reflux disease supports the concept that the "transition zone" between distal esophagus and proximal stomach is affected by gastroesophageal reflux disease as well, and architectural and molecular changes in the desmosomal compartment contribute to the pathogenesis of gastroesophageal reflux disease in the cardia mucosa.

    An accurate reflux-symptom relationship analysis method is an unmet need in gastroesophageal reflux disease (GERD) diagnosis. The aim of this study was to adapt signal detection theory (SDT) approach to reflux-symptom relationship analysis to develop a new diagnosis method. Patients with predominant symptoms of heartburn and regurgitation were enrolled. Proton pump inhibitor (PPI)-responsive and PPI-unresponsive groups were created via interview and PPI trial. Patients then underwent stationary esophageal manometry and 24-hour multichannel intraluminal impedance-pH monitoring. SDT measurement parameters (discriminability: d' and criterion: c) were calculated using empirically selected time windows (0.5, 1, 2, 3, 4 and 5 minutes). The time window that provided the highest d' value was selected as the optimal time window. A cut-off d' value that optimally separates two groups was found using receiver operating characteristics analysis. Sixty-three patients completed the study (45 PPI responsive). Optimal time window and cut-off d' value were found as 1 and 0.767 minute, respectively. Symptom association probability (SAP) index values showed good correlation (rS = 0.7182, P < 0.0001) with d' values. SDT approach to reflux-symptom relationship analysis showed sensitivity (89% vs. 78%) and negative predictive values (75% vs. 60%) favorable over SAP index analysis. SDT approach using 1-minute time window and 0.767 cut-off d' value provides us a new and more accurate measure of reflux-symptom relationship than SAP index analysis.

    The resistance of the lower esophageal sphincter to reflux of gastric juice is determined by the integrated effects of radial pressures exerted over the entire length of the sphincter. This can be quantitated by three-dimensional computerized imaging of sphincter pressures obtained by a pullback of radially oriented pressure transducers and by calculating the volume of this image, in other words, the sphincter pressure vector volume. Validation studies showed that sphincter imaging based on a stepwise pullback of a catheter with four or eight radial side holes is superior to a rapid motorized pullback. Compared with 50 healthy volunteers, the total and abdominal sphincter pressure vector volume was lower in 150 patients with increased esophageal acid exposure (p less than 0.001) and decreased with increasing esophageal mucosal damage (p less than 0.01). Calculation of the sphincter pressure vector volume was superior to standard techniques in identifying a mechanically defective sphincter as the cause of increased esophageal acid exposure, particularly in patients without mucosal damage. The Nissen and Belsey fundoplication increased the total and intra-abdominal sphincter pressure vector volume (p less than 0.001) and normalized the three-dimensional sphincter image. Failure to do so was associated with recurrent or persistent reflux. These data indicate that three-dimensional imaging of the lower esophageal sphincter improves the identification of patients who would benefit from an antireflux procedure. Analysis of the three-dimensional sphincter pressure profile should become the standard for evaluation of the lower esophageal sphincter. PMID:1953093

    Many symptoms have been recognized in association with laryngo-pharyngeal reflux disease (LPRD), but reports of perceptual voice disorders in this condition have been lacking to date. Forty-nine patients with suspected LPRD were studied for five specific perceptual voice characteristics, and these characteristics were compared to the same characteristics in individuals who had never seen an Otolaryngologist for a voice disorder or throat problem (controls). Sixteen of the suspected LPRD patients also underwent 24-hour pH probe studies. All patients with suspected LPRD had significantly increased abnormal perceptual voice characteristics (musculoskeletal tension, hard glottal attack, glottal fry, restricted tone placement, and hoarseness) compared to the controls. Statistical objective differences between the two groups was demonstrated by the presence of increased shimmer in patients with suspected LPRD compared to controls. The differential diagnosis between functional voice disorders and LPRD may be complex, and perceptual parameters may overlap. Interdisciplinary evaluation is advocated.

    Optimisation of proton pump inhibitors use may improve reflux symptoms in 20-25% of the patients. Pathological gastro-oesophageal reflux should be documented in a patient with refractory reflux symptoms using upper endoscopy and/or pH testing. While on proton pump inhibitors twice daily, persistent symptoms are not related to gastro-oesophageal refluxdisease(GERD) in 50% of the patients. The new anti-reflux compounds have yet a limited efficacy and side effects that currently limit their development.

    AIM To determine whether capsaicin infusion could influence heartburn perception and secondary peristalsis in patients with gastroesophageal reflux disease (GERD). METHODS Secondary peristalsis was performed with slow and rapid mid-esophageal injections of air in 10 patients with GERD. In a first protocol, saline and capsaicin-containing red pepper sauce infusions were randomly performed, whereas 2 consecutive sessions of capsaicin-containing red pepper sauce infusions were performed in a second protocol. Tested solutions including 5 mL of red pepper sauce diluted with 15 mL of saline and 20 mL of 0.9% saline were infused into the mid-esophagus via the manometric catheter at a rate of 10 mL/min with a randomized and double-blind fashion. During each study protocol, perception of heartburn, threshold volumes and peristaltic parameters for secondary peristalsis were analyzed and compared between different stimuli. RESULTS Infusion of capsaicin significantly increased heartburn perception in patients with GERD (P < 0.001), whereas repeated capsaicin infusion significantly reduced heartburn perception (P = 0.003). Acute capsaicin infusion decreased threshold volume of secondary peristalsis (P = 0.001) and increased its frequency (P = 0.01) during rapid air injection. The prevalence of GERD patients with successive secondary peristalsis during slow air injection significantly increased after capsaicin infusion (P = 0.001). Repeated capsaicin infusion increased threshold volume of secondary peristalsis (P = 0.002) and reduced the frequency of secondary peristalsis (P = 0.02) during rapid air injection. CONCLUSION Acute esophageal exposure to capsaicin enhances heartburn sensation and promotes secondary peristalsis in gastroesophageal reflux disease, but repetitive capsaicin infusion reverses these effects.

The subjects were 47 patients with gastroesophageal reflux disease with residual symptoms such as heartburn following 8 weeks of proton pump inhibitor therapy. We administered these subjects rikkunshito in combination with a proton pump inhibitor for 6–8 weeks. We scored their symptoms of heartburn, fullness, abdominal discomfort, and abdominal pain, and surveyed their quality of life using the Reflux Esophagitis Symptom Questionnaire, comprising questions concerning daily activities, meals (changes in amount and favorite foods), and sleep (getting to sleep and early morning waking). Improvement was seen in all symptoms, and quality of life scores for meals and sleep also improved. These results indicate that combination therapy with rikkunshito and a proton pump inhibitor improves quality of life related to eating and sleep in patients with patients with proton pump inhibitor-refractory gastroesophageal reflux disease.

    Objective Gastroesophageal reflux disease (GERD) is a common disease which can cause troublesome symptoms and affect quality of life. In addition to esophageal complications, GERD may also be a risk factor for extra-esophageal complications. Both GERD and coronary artery disease (CAD) can cause chest pain and frequently co-exist. However, the association between GERD and acute myocardial infarction (AMI) remain unclear. The purpose of the study was to compare the incidence of acute myocardial infarction in GERD patients with an age-, gender-, and comorbidity matched population free of GERD. We also examine the association of the risk of AMI and the use of acid suppressing agents in GERD patients. Methods We identified patients with GERD from the Taiwan National Health Insurance Research Database. The study cohort comprised 54,422 newly diagnosed GERD patients; 269,572 randomly selected age-, gender-, comorbidity-matched subjects comprised the comparison cohort. Patients with any prior CAD, AMI or peripheral arterial disease were excluded. Incidence of new AMI was studied in both groups. Results A total 1,236 (0.5%) of the patients from the control group and 371 (0.7%) patients from the GERD group experienced AMI during a mean follow-up period of 3.3 years. Based on Cox proportional-hazard model analysis, GERD was independently associated with increased risk of developing AMI (hazard ratio (HR) = 1.48; 95% confidence interval (CI): 1.31–1.66, P < 0.001). Within the GERD group, patients who were prescribed proton pump inhibitors (PPIs) for more than one year had slightly decreased the risk of developing AMI, compared with those without taking PPIs (HR = 0.57; 95% CI: 0.31–1.04, P = 0.066). Conclusions This large population-based study demonstrates an association between GERD and future development of AMI, however, PPIs use only achieved marginal significance in reducing the occurrence of AMI in GERD patients. Further prospective studies are needed to evaluate

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

    Purpose The aim of this study was to evaluate bolus transit during esophageal swallow (ES) and gastroesophageal reflux (GER) events and to investigate the relationship between the characteristics of ES and GER events in a population of term and preterm newborns with symptoms of gastroesophageal reflux disease (GERD). Methods The study population consisted of term and preterm newborns referred to combined multichannel intraluminal impedance (MII) and pH monitoring for GERD symptoms. The frequency and characteristics of ES and GER events were assessed by two independent investigators. Statistical significance was set at p<0.05. Results Fifty-four newborns (23 preterm) were included in the analyses. Median bolus head advancing time corrected for esophageal length (BHATc) was shorter during mealtime than during the postprandial period (median, interquartile range): 0.20 (0.15-0.29) s/cm vs. 0.47 (0.39-0.64) s/cm, p<0.001. Median bolus presence time (BPT) was prolonged during mealtime: 4.71(3.49-6.27) s vs. 2.66 (1.82-3.73) s, p<0.001. Higher BHATc (p=0.03) and prolonged BPT (p<0.001) were observed in preterm newborns during the postprandial period. A significant positive correlation between BHATc and bolus clearance time was also observed (ρ=0.33, p=0.016). Conclusion The analysis of ES and GER events at the same time by MII provides useful information to better understand the physiopathology of GERD. In particular, the analysis of BHATc during the postprandial period could help clinicians identify newborns with prolonged esophageal clearance time due to impaired esophageal motility, which could allow for more accurate recommendations regarding further tests and treatment.

Clinical tools for symptoms severity assessment should be discriminative, predictive and evaluative. Methods In this study we compared a patient-oriented symptoms evaluation (ReQuest™) vs a structured interview assessment initiated by a physician (sickness impact profile [SIP]). Both questionnaires were analyzed in a multidimensional space using latent factors. Five dimensions were found: 1 for the short ReQuest™ questionnaire and 4 for SIP. Results We included 1,522 women and 1,296 men; mean age was 36 ± 7 years, and mean body mass index was 26 ± 4. The score questionnaire assessment evaluation by physicians and patients did not correlate between them (between r = 0.03 and 0.26) except nausea and sleep disorder (r = 0.45 and 0.51) but both were sensitive enough to detect changes after treatment (P < 0.05). Medical specialty of the physician showed effect on the score of both, ReQuest™ and SIP evaluation. Questionnaire variance decomposition due to specialist was only 2% (P < 0.05). Conclusions While both evaluations are orthogonal (non-correlated), meaning patients and physicians measured diverse aspects of the same disease, they both were able to measure patient's improvement with treatment.

    The aim of the study was to evaluate the impact of meal volume, weight change, excessive weight, and caloric content of the ration on disease's manifestation and progression from data presented in the published scientific literature. Systematic review in PubMed/Medline databased was performed with key words: food, dietary patterns, nutrients, nutrition, meal volume, calorie in combination with gastroesophageal reflux and GERD. 113 articles were found and 29 of them were selected according to the following criteria: the article should contain data of clinical observations, or to be a result of meta-analysis; study group characteristic, study design, and results should have been available for the analysis. The review contains data concerning influence of body mass index, its change; meal volume and caloric content of the ration on clinical manifestations of GERD. The dietotherapy recommendations for this illness include exclusion of overeating, limitation in use of high-caloric foods, increased protein content in diet, the adherence of 3-4 meals daily, with the last meal at 2-3 hours before sleep. However, the majority of the recommendations on the use of dietary nutrition is mainly based on the empiric experience, not on scientific data, and that doesn't allow to prepare reasonable recommendations for changing the diet of the patients with GERD. There is a need for prospective studies of influence of diet correction on course of the disease.

    Appendicitis and gastroesophageal reflux disease (GERD) are both prevalent diseases and might share similar pathological mechanisms. The aim of this study was to investigate the association between GERD and appendicitis using a large population-based dataset. This study used administrative claims data from the Taiwan Longitudinal Health Insurance Database 2005. We identified 7113 patients with appendicitis as cases, and 28452 matched patients without appendicitis as controls. This study revealed that GERD was found in 359 (5.05%) cases and 728 (2.56%) controls (p < 0.001). Conditional logistic regression shows that the adjusted odds ratio (OR) of GERD for cases was 2.05 (95% confidence interval (CI): 1.08~2.33) compared to controls. The adjusted ORs of prior GERD for patients aged 18~39, 40~59, and ≥60 years with appendicitis were 1.96 (95% CI: 1.56~2.47), 2.36 (95% CI: 1.94~2.88), and 1.71 (95% CI: 1.31~2.22) than controls, respectively. We concluded that patients with appendicitis had higher odds of prior GERD than those without appendicitis regardless of age group.

  5. On-demand and intermittent therapy for gastro-oesophageal reflux disease: economic considerations.

    Since gastro-oesophageal reflux disease (GORD) is a prevalent condition characterised by frequent relapses, long-term costs of management for this disease are high. Thus, strategies to decrease resource expenditures without impairing patient quality of life are desirable. On-demand therapy (one-dose when symptoms occur) and intermittent therapy (short course of medication when symptoms occur) are attractive since pharmaceutical expenditures may be decreased, and many patients self-employ this strategy. The purpose of this paper was to examine the economic implications of on-demand or intermittent therapy for GORD. A review of selected studies evaluating medication suitable for on-demand or intermittent administration was performed. A complete search for published studies on the cost effectiveness of on-demand or intermittent therapy for GORD was conducted, and the results discussed in detail. Antacids, alginates, topically active agents, histamine(2)-receptor antagonists, and proton pump inhibitors have all demonstrable efficacy compared with placebo when administered on-demand. Proton pump inhibitors constitute the most effective pharmacological means to treat GORD. Although step-up strategies initially using less potent medication may decrease resource use, cost-effectiveness analysis illustrates that on-demand or intermittent therapy with proton pump inhibitors may be reasonable options. Further work that defines quality of life and patient preferences associated with GORD may allow for proper allocation of resources for the management of this condition.

    Airway symptoms are often caused by aspiration of refluxed materials into the larynx. In this study we sought to define the frequency, character, and proximal extent of refluxed contents - including nonacid reflux-in normal subjects using intraluminal impedance to improve our understanding of the relationship between reflux and aspiration. Ten subjects, who had no symptoms of gastroesophageal reflux disease or airway disease, underwent impedance/pH monitoring with a catheter that allowed simultaneous esophageal and pharyngeal monitoring. Impedance detected 496 gastroesophageal reflux episodes in the 10 subjects during 240 hours of study. The majority, 399 (81% of the total) were acid reflux episodes (pH < 4). Ninety-seven were nonacid (pH > 4). Most reflux episodes (348 of 496) reached the mid esophagus (9 cm above lower esophageal sphincter). There were 51 reflux episodes that reached the pharynx (PR). Only 13 (25%) of PR were acidic (pH < 4), while 38 were nonacid. Twenty-six PR episodes were liquid and 25 were mixed (liquid and gas). The median number of PR episodes measured with impedance was 5 (0-10). In asymptomatic subjects, most episodes of gastroesophageal reflux are acidic and reach the midesophagus. Reflux into the PR appears to be more common than previously believed, and most of these episodes are not acidic. Thus, traditional 24-hour pH monitoring may underestimate the presence of pharyngeal reflux. The combination of impedance with pH monitoring markedly enhances our ability to accurately detect potential microaspiration.

    BACKGROUND Gastroesophageal reflux disease (GERD) is one of the most common gastrointestinal problems worldwide. The aim of this study was to evaluate the clinical spectrum, prevalence, and some of the variables that are supposed to be the risk factors of this chronic disorder. METHODS This population- based cross-sectional study was conducted in a one-stage randomized clustered sample of adult inhabitants in Kerman city in 2011-2012. A total of 2265 subjects with age range of 15-85 years were enrolled. Face to face interview was performed for all the subjects. GERD was defined as at least weekly heart burn and/or acid regurgitation during the past year. Association of GERD with factors like demographic variables, medical condition, diet and life habits were analyzed. RESULTS A total of 2265 subjects including 988 (43.8%) male and 1275 (56.3%) female patients were evaluated. The prevalence of GERD was 28%. The prevalence was higher in female patients and with aging. There was also a significant association between GERD and the following risk factors: lower educational level (p <0.0001), higher body mass index (p =003), presence of depression(p<0.0001), and anxiety (p <0=0001). CONCLUSION GERD as a common disorder in our region was seen more in elderly and female patients and was associated with some anthropometric, metabolic, medical conditions, and behavioral habits.

    The association between gastroesophageal reflux (GER) and intestinal malrotation (IM) has been well described. Delayed or impaired gastric emptying in IM is thought to be a contributing factor in the development of gastroesophageal reflux disease (GERD). The current study assessed the role of malrotation in delayed gastric emptying in children with GERD. We also evaluated the interactions between GERD, malrotation, gastric pH abnormalities, and gastric dysmotility. Sixty-seven patients between 1 and 5 years of age (mean 3.08+/-1.2) and with symptoms of GER, such as emesis, reactive or recurrent lung disease, and/or growth retardation, were studied in 2001-2005. Upper and lower gastrointestinal contrast studies were performed for the diagnosis of malrotation. Gastric motility was evaluated with a liquid gastric emptying protocol. GER was documented by upper gastrointestinal studies, scintigraphy, and/or 24-h pH monitoring. In our series of 44 children with GERD, there was an unexpectedly high incidence of IM: 54.5% (24/44). IM has previously been known to occur in 25% of patients with GERD. GERD was found in 24 (82.7%) of 29 patients with IM. Mean nuclear gastric emptying (MNGE) was 51.6+/-8.04 min in patients with isolated GERD and 96.6+/-20.5 min in children with IM and GERD. There was a statistically significant difference in MNGE time (p<0.05) between children with primary GERD and in those with GERD and IM. Esophageal pH monitoring showed that mean fraction time below pH 4 was 7.06+/-1.1% in patients with isolated GERD and 14.7+/-4.1% in patients with IM and GERD. GERD is common in children between 1 and 5 years old. Using gastric emptying studies and esophageal pH monitoring, we have shown that gastric dysmotility and esophageal pH abnormalities are highly prevalent, especially in children with malrotation compared with children with isolated GERD. These findings suggest that malrotation is an important factor responsible for delayed gastric emptying in GERD

    The gastroesophageal reflux (GER) disease is a very frequent digestive disorder, mainly characterised by the reflux of the gastric acidic content to the esophage in abnormal quantities. There are different situations that favour this situation but almost in all of them rely an incompetence of the esophagic sphincter. The clinical consequences are many, including oral manifestations. Among all of them the most frequent is the esophagitis followed by symptoms at the pharynx or larynx and finally, the oral cavity. At this level fundamentally we will find enamel and oral mucosa erosions. We report the case of a patient who was indirectly diagnosed of her esophague disease by the observation of the alterations in the occlusal splint induced by the gastric reflux. We review the literature concerning the above topic and its possible association with the miofascial syndrome.

    Background/Aims Little data exists about esophageal body dysmotility and reflux patterns in refractory gastroesophageal reflux disease (RGERD) patients off therapy. We aimed to evaluate effects of esophageal body dysmotility on reflux parameters in RGERD patients by combining impedance-pH monitoring and high-resolution manometry (HRM). Methods We retrospectively reviewed the impedance-pH data and HRM metrics in patients with refractory gastroesophageal reflux symptoms. Impedance-pH monitoring and manometric data were compared between 2 groups: ineffective esophageal motility (IEM) and normal motility. Results Forty-eight patients (30 males, mean age 54.5 years) were included (16 erosive esophagitis, 24 non-erosive reflux disease, and 8 functional heartburn), amongst which 24 subjects showed IEM, and others had normal motility. Number of patients who had a large break in the IEM group was significantly higher than that of normal motility patients. IEM group had more patients with weakly acid reflux and long term acid reflux than the normal group (P = 0.008, P = 0.004, respectively). There was no statistical difference in baseine impedance levels from z4 to z6 between the 2 groups (2911 ± 1160 Ω vs 3604 ± 1232 Ω, 2766 ± 1254 Ω vs 3752 ± 1439 Ω, 2349 ± 1131 Ω vs 3038 ± 1254 Ω, all P > 0.05). Acid exposure time, numbers of long term acid reflux and weakly acid reflux showed strong negative correlation with esophageal body motility and/or lower esophageal sphincter function. Conclusions IEM was associated more with acid exposure, abnormal weakly acid reflux, and long term acid reflux in RGERD patients. These data suggested the role of esophageal body dysmotility in the pathophysiological mechanisms of RGERD patients. PMID:27599539

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

    Tooth wear is a multifactorial process that is a growing concern in dentistry. This phenomenon can be caused by mechanical (attrition, abrasion, or abfraction) or chemical (erosion) processes. Etiologic factors in dental erosion can be due to changes in behavior, an unbalanced diet, or gastrointestinal disorders such as acid regurgitation, which may influence the salivary flow rate and buffering capacity of saliva. This case report describes an esthetic rehabilitation of a patient with gastroesophageal reflux and dental erosion, with a treatment rationale that includes the use of a diagnostic template and five-year follow-up. This technique, presented here in a clinical case with moderate enamel loss, integrates an additive wax-up and a direct intraoral bis-acryl resin mock-up. Lithium disilicate glass-ceramic (IPS e.max Press, Ivoclar Vivadent) laminate veneers were fabricated with the heatpress technique. They were veneered with a layering ceramic (IPS e.max Ceram, Ivoclar Vivadent) to improve the appearance of the incisal edge. The case demonstrated the success of veneers as an effective, conservative, and esthetic treatment for patients with this pathology.

    Background/Aims Gastroesophageal reflux disease (GERD) is the most common cause of non-cardiac chest pain (NCCP). Currently available data reveal a weak relationship between NCCP and dysmotility. Moreover, it is unclear why some refluxes are perceived as heartburn and others as NCCP. We aimed to evaluate the role of the reflux pattern and the esophageal motility in patients with NCCP. Methods Forty-eight patients with NCCP (Group 1) and 50 only typical GERD symptoms (Group 2) were included and underwent high-resolution manometry (HRM) and multichannel intraluminal impedance-pH monitoring. Results Impaired peristalsis was found in 60% of patients with NCCP and in 24% of patients with typical symptoms (P < 0.05). In patients belonging to Group 1, the majority of reflux episodes associated with chest pain were acid and mixed. The proportion of mixed refluxes was higher than that in Group 2. In Group 1, the reflux clearing time at 5, 9, and 15 cm, measured in reflux episodes associated to NCCP was longer than in reflux episodes associated to typical symptoms (mean ± 95% CI: 27.2 ± 5.6, 23.3 ± 4.4, and 14.6 ± 2.3 seconds vs 18.3 ± 3.5, 13.3 ± 2.2, and 11.1 ± 1.8 seconds; P < 0.01). Conclusions The presence of gas in the refluxate seems to be associated with NCCP. The impaired motility observed in NCCP patients may play a relevant role in delaying reflux clearing, hence increasing the time of contact between refluxate and esophageal mucosa. PMID:27095707

    Several studies indicate a significant degree of overlap between irritable bowel syndrome (IBS) and gastroesophageal reflux disease (GERD). Likewise, both functional heartburn (FH) and IBS are functional digestive disorders that may occur in the same patients. However, data establishing a solid link between FH and IBS are lacking, mainly because the clinical definition of FH has undergone substantial changes over the years. The available literature on the overlap between GERD or FH and IBS highlights considerable heterogeneity in terms of the criteria and diagnostic procedures used to assess heartburn and IBS. In particular, several epidemiological studies included patients with concomitant IBS and GERD without any attempt to distinguish FH (as defined by the Rome III criteria) from GERD via pathophysiological investigations. Independent of these critical issues, there is preliminary evidence supporting a significant degree of FH-IBS overlap. This underscores the need for studies based on updated diagnostic criteria and accurate pathophysiological classifications, particularly to distinguish FH from GERD. This distinction would represent an essential starting point to achieving a better understanding of pathophysiology in the subclasses of patients with GERD and FH and properly assessing the different degrees of overlap between IBS and the subcategories of heartburn.The present review article intends to appraise and critically discuss current evidence supporting a possible concomitance of GERD or FH with IBS in the same patients and to highlight the pathophysiological relationships between these disorders.

    Introduction In patients with gastroesophageal reflux disease (GORD), co-existence of functional dyspepsia (FD) is known to be associated with poor response to proton pump inhibitors (PPIs), but the contribution of specific dyspepsia symptoms has not yet been systematically investigated. Objective We aimed to characterize the impact of dyspepsia symptoms on response to PPIs in patients with GORD. Methods The enrolled subjects were consecutive patients with a diagnosis of GORD. All patients underwent a 24 hour pH–impedance test, while on PPI therapy. Patients were divided into two groups, refractory and responders, according to the persistence of GORD symptoms. A standardized questionnaire for FD was also administered to assess presence of dyspepsia symptoms. Results In the subgroup of refractory patients FD was more prevalent than in responders, with post-prandial fullness, nausea, vomiting, early satiation and epigastric pain being significantly prevalent in refractory GORD patients. In the multivariate analysis only early satiation and vomiting were significantly associated with poor response to PPIs. Conclusion Co-existence of FD is associated with refractory GORD. We showed that only early satiation and vomiting are risk factors for poor response to therapy with PPIs. Our findings suggest that symptoms of early satiation and vomiting would help to identify the subset of PPI-refractory GORD patients.

    AIM To evaluate the prevalence of gastroesophageal reflux disease (GERD) with additional symptoms, relationship with Helicobacter pylori (H. pylori) of this country-wide study. METHODS Data from 3214 adults were obtained with validated questionnaire. Eight hundred and forty-one subjects were randomized to be tested for H. pylori via the urea breath test. "Frequent symptoms" were defined heartburn and/or regurgitation occurring at least weekly. RESULTS The prevalence of GERD was 22.8%, frequent and occasional heartburn were 9.3%-12.7%, regurgitation were 16.6%-18.7%, respectively. Body mass index (BMI) ≤ 18.5 showed a prevalence of 15%, BMI > 30 was 28.5%. The GERD prevalence was higher in women (26.2%) than men (18.9%) (P < 0001). Overall prevalence of H. pylori was 75.7%. The prevalence was 77.1% in subjects without symptoms vs 71.4% in subjects with GERD (χ2 = 2.6, P = 0.27). Underprivileged with the lowest income people exhibit a higher risk. CONCLUSION GERD is common in Turkey which reflects both Western and Eastern lifestyles with high rate of H. pylori. The presence of H. pylori had no effect on either the prevalence or the symptom profile of GERD. Subjects showing classical symptoms occasionally exhibit more additional symptoms compared with those without classical symptoms. PMID:28210089

    Gastro-esophageal reflux disease (GERD) is a very common disorder that results primarily from the loss of an effective antireflux barrier, which forms a mechanical obstacle to the retrograde movement of gastric content. GERD can be currently treated by medical therapy, surgical or endoscopic transoral intervention. Medical therapy is the most common approach, though concerns have been increasingly raised in recent years about the potential side effects of continuous long-term medication, drug intolerance or unresponsiveness, and the need for high dosages for long periods to treat symptoms or prevent recurrences. Surgery too may in some cases have consequences such as long-lasting dysphagia, flatulence, inability to belch or vomit, diarrhea, or functional dyspepsia related to delayed gastric emptying. In the last few years, transoral incisionless fundoplication (TIF) has proved an effective and promising therapeutic option as an alternative to medical and surgical therapy. This review describes the steps of the TIF technique, using the EsophyX® device and the MUSETM system. Complications and their management are described in detail, and the recent literature regarding the outcomes is reviewed. TIF reconfigures the tissue to obtain a full-thickness gastro-esophageal valve from inside the stomach, by serosa-to-serosa plications which include the muscle layers. To date the procedure has achieved lasting improvement of GERD symptoms (up to six years), cessation or reduction of proton pump inhibitor medication in about 75% of patients, and improvement of functional findings, measured by either pH or impedance monitoring.

    Proton pump inhibitors (PPIs) are commonly prescribed to infants and children for managing gastroesophageal reflux disease (GERD). Recently published literature illustrates conflicting evidence on the efficacy of PPIs in infants and children. Randomized controlled trials and systematic reviews have demonstrated a lack of efficacy of PPIs, specifically in young infants. Furthermore, emerging evidence also suggests that PPIs are not as benign as once thought, with newer data implicating a potential association of PPIs with an increased risk of respiratory tract infections, gastrointestinal infections, bone fractures, hypomagnesemia, and the occurrence of rebound hyperacidity after discontinuation of PPI therapy. To summarize the emerging data in children, we reviewed the literature to assess the efficacy and safety of PPIs in managing pediatric GERD. Despite conflicting evidence on the efficacy of PPIs, most studies in children demonstrated some benefit when compared with placebo. With respect to the safety of PPIs in children, only a few small studies and case reports indicated a potential association of PPIs with an increased risk of respiratory tract or gastrointestinal infections, bone fractures, and hypomagnesemia; however, many of those studies had their own limitations. From the review, it is clear that further well-designed trials and observational studies are needed to shed more light on the efficacy and safety of PPIs in the pediatric population.

    Gastroesophageal reflux disease (GERD) is caused by abnormal reflux of gastric contents into the esophagus. GERD can be divided into two groups, erosive esophagitis and non-erosive reflux disease (NERD). The aim of this study was to compare the clinical characteristics of patients with erosive esophagitis to those with NERD. All participating patients underwent an upper endoscopy during a voluntary health check-up. The NERD group consisted of 500 subjects with classic GERD symptoms in the absence of esophageal mucosal injury during upper endoscopy. The erosive esophagitis group consisted of 292 subjects with superficial esophageal erosions with or without typical symptoms of GERD. Among GERD patients, male gender, high body mass index, high obesity degree, high waist-to-hip ratio, high triglycerides, alcohol intake, smoking and the presence of a hiatal hernia were positively related to the development of erosive esophagitis compared to NERD. In multivariated analysis, male gender, waist-to-hip ratio and the presence of a hiatal hernia were the significant risk factors of erosive esophagitis. We suggest that erosive esophagitis was more closely related to abdominal obesity. PMID:20808675

    Purpose We tried to evaluate the difference in the expression of carbonic anhydrase (CA) III and heat shock protein (Hsp) 70 between laryngopharyngeal reflux disease (LPRD) and non-LPRD patients. Materials and Methods The study involved 28 patients who underwent laryngeal microsurgery due to benign laryngeal disease from March to August 2008. Reflux symptom index (RSI) and reflux finding score (RFS) were measured for each person, and they were assigned either to the LPRD group (n=10) or non-LPRD group (n=18). Tissue samples were obtained from the mucosa of posterior commissure, and immunohistochemistry (IHC) staining of CAIII and Hsp70 was performed. The IHC scores were measured and compared with clinical features including RSI and RFS. Results Total 10 patients were assigned as LPRD group, and 18 patients were as control group. The mean IHC score of CAIII and Hsp70 was 1.70±1.06 and 1.90±0.88, respectively, in LPRD patients, whereas the mean IHC score of CAIII and Hsp70 was 0.78±0.73 and 0.94±0.87, respectively, in non-LPRD patients. The difference between two groups was statistically significant (p<0.05). Conclusion CAIII and Hsp70 expressions were higher in LPRD patients that in non-LPRD patients, suggesting the possibility as one of biomomarker in LPRD diagnosis. PMID:26847302

The aim of this study was to investigate the association of medications for lifestyle-related diseases with reflux esophagitis (RE). Methods We conducted a hospital-based, cross-sectional retrospective study of consecutive outpatients who received an upper gastrointestinal endoscopy in our department from February 2008 to November 2014, which was performed by one specialist who was a member of the Japan Gastroenterological Endoscopy Society. We investigated the patient profile, Helicobacter pylori (H. pylori) infection status, medications for lifestyle-related diseases (including calcium channel blockers, statins, and bisphosphonates), and upper gastrointestinal endoscopic findings (RE, hiatal hernia, Barrett’s mucosa, and endoscopic gastric mucosal atrophy [EGA]). Patients with gastrectomy, peptic ulcer disease, gastric or esophageal malignant disease, and those who used proton pump inhibitors or histamine-2 receptor antagonists were excluded. We divided the subjects into a group without RE (RE(−)) and a RE (RE(+)) group as judged by endoscopy, and investigated the risk factors for RE. Results Of 1,744 consecutive cases, 590 cases (300 males and 290 females; mean age 60.5±13.2 years) were eligible. RE(−) and RE(+) cases numbered 507 and 83, respectively. Bivariate analysis showed significant positive associations of RE with male sex, body mass index (BMI), calcium channel blockers, Barrett’s mucosa, hiatal hernia and negative associations of RE with H. pylori positivity, EGA. Multivariate analysis showed significant positive associations of RE with BMI (odds ratio [OR]: 1.20, 95% confidence interval [95% CI]: 1.10–1.29), use of calcium channel blockers (OR: 2.12, 95% CI: 1.16–3.87), Barrett’s mucosa (OR: 2.97, 95% CI: 01.64–5.38), hiatal hernia (OR: 3.13, 95% CI: 1.79–5.47) and negative

    AIM: To investigate whether there is a link between diabetes mellitus (DM) and gastroesophageal reflux disease (GERD). METHODS: We conducted a systematic search of PubMed and Web of Science databases, from their respective inceptions until December 31, 2013, for articles evaluating the relationship between DM and GERD. Studies were selected for analysis based on certain inclusion and exclusion criteria. Data were extracted from each study on the basis of predefined items. A meta-analysis was performed to compare the odds ratio (OR) in DM between individuals with and without GERD using a fixed effect or random effect model, depending on the absence or presence of significant heterogeneity. Subgroup analyses were used to identify sources of heterogeneity. Publication bias was assessed by Begg’s test. To evaluate the results, we also performed a sensitivity analysis. RESULTS: When the electronic database and hand searches were combined, a total of nine eligible articles involving 9067 cases and 81 968 controls were included in our meta-analysis. Based on the random-effects model, these studies identified a significant association between DM and the risk of GERD (overall OR = 1.61; 95%CI: 1.36-1.91; P = 0.003). Subgroup analyses indicated that this result persisted in studies on populations from Eastern countries (OR = 1.71; 95%CI: 1.38-2.12; P = 0.003) and in younger patients (mean age < 50 years) (OR = 1.70; 95%CI: 1.22-2.37; P = 0.001). No significant publication bias was observed in this meta-analysis using Begg’s test (P = 0.175). The sensitivity analysis also confirmed the stability of our results. CONCLUSION: This meta-analysis suggests that patients with DM are at greater risk of GERD than those who do not have DM. PMID:25780309

    AIM: To analyze the potential relationship between gastroesophageal reflux disease (GERD) and the development of atrial fibrillation (AF). METHODS: Using the key words “atrial fibrillation and gastroesophageal reflux”, “atrial fibrillation and esophagitis, peptic”, “atrial fibrillation and hernia, hiatal” the PubMed, EMBASE, Cochrane Library, OVIDSP, WILEY databases were screened for relevant publications on GERD and AF in adults between January 1972-December 2013. Studies written in languages other than English or French, studies not performed in humans, reviews, case reports, abstracts, conference presentations, letters to the editor, editorials, comments and opinions were not taken into consideration. Articles treating the subject of radiofrequency ablation of AF and the consecutive development of GERD were also excluded. RESULTS: Two thousand one hundred sixty-one titles were found of which 8 articles met the inclusion criteria. The presence of AF in patients with GERD was reported to be between 0.62%-14%, higher compared to those without GERD. Epidemiological data provided by these observational studies showed that patients with GERD, especially those with more severe GERD-related symptoms, had an increased risk of developing AF compared with those without GERD, but a causal relationship between GERD and AF could not be established based on these studies. The mechanisms of AF as a consequence of GERD remain largely unknown, with inflammation and vagal stimulation playing a possible role in the development of these disorders. Treatment with proton pomp inhibitors may improve symptoms related to AF and facilitate conversion to sinus rhythm. CONCLUSION: Although links between AF and GERD exist, large randomized clinical studies are required for a better understanding of the relationship between these two entities. PMID:25071357

    One of the most frequent complications after laparoscopic antireflux surgery is intrathoracic migration of the wrap ("slipped" Nissen fundoplication). The most common reasons for this are inadequate closure of the crura or disruption of the crural closure. The aim of this prospective study was to evaluate surgical outcomes in patients who underwent laparoscopic antireflux surgery with simple nonabsorbable polypropylene sutures for hiatal closure in comparison to patients who underwent routine mesh-hiatoplasty. Between 1993 and 1998, a group of 361 patients underwent primary laparoscopic Nissen or Toupet fundoplication with the use of simple nonabsorbable polypropylene sutures for hiatal closure. Since December 1998, in all patients (n = 170) who underwent laparoscopic antireflux surgery, a 1 x 3 cm polypropylene mesh was placed on the crura behind the esophagus to reinforce them. Functional outcome, symptoms of gastroesophageal reflux disease, and postoperative complications such as recurrent hiatal hernia with or without intrathoracic migration of the wrap have been used for assessment of outcomes. In the initial series of 361 patients, postoperative herniation of the wrap occurred in 22 patients (6.1%). Of these 22 patients, 17 of them (4.7%) had to undergo laparoscopic redo surgery. The remaining five patients were free of symptoms. In comparison to these results, in a second group of 170 patients there was only one (0.6%) who had postoperative herniation of the wrap into the chest. There have been no significant differences in objective data such as DeMeester scores or lower esophageal sphincter pressure between the two groups. Postoperative dysphagia was increased during the early period after surgery in patients undergoing mesh-hiatoplasty but resolved without any further treatment within the first year after laparoscopic antireflux surgery. We concluded that routine hiatoplasty with the use of a polypropylene mesh is effective in preventing postoperative

    Abstract The 24-hour esophageal pH-metry is the most widely used method to diagnose the gastroesophageal reflux disease (GERD). The study compares the different scores obtained during the 24-hour esophageal pH-metry. A retrospective study over 5 years including 234 children (1 month and 18 years old) admitted in a pediatric gastroenterology regional center in Northeast Romania, with suspicion of GERD. They underwent 24- hour esophageal pH-metry, and the scores obtained (Boix-Ochoa, DeMeester, Johnson-DeMeester) were compared. Out of the 234 children, 172 (73.50%) had positive Boix-Ochoa score and 62 (26.50%) had normal Boix-Ochoa score (<11.99). Based on the DeMeester score, 149 children (63.68%) were positive and 85 (36.32%) were negative. The correlation of the Demeester score with the Boix-Ochoa score was very high (r = 0.978, P <  < 0.01, 95% confidence interval). Considering the Johnson-DeMeester score, 120 cases (51.28%) had GERD and 114 (48.72%) did not. The correlation of the Johnson-DeMeester score with the Boix-Ochoa score was still high (r = 0.94, P <  < 0.01, 95% 95% confidence interval). As considered until now, the Boix-Ochoa score is the most accurate score to be used in pediatrics for the diagnosis of GERD. The use of the different scores—Boix-Ochoa, DeMeester, Johnson-DeMeester—showed a high sensitivity and specificity of the pH-metry measurements applied to the study lot, but the last score has a higher risk of false-negative results.

    Background/Aims The study aimed to determine pre- and post-fundoplication esophagogastric junction (EGJ) pressure and esophageal peristalsis by high-resolution manometry (HRM) in patients with gastroesophageal reflux disease (GERD). Methods Pre-operative and post-operative HRM data from 25 patients with GERD were analyzed using ManoView version 2.0.1. with updated software for Chicago classification and pressure topography. The study involved swallowing water boluses of 10 mL in the upright position. Results Significant increase of mean basal EGJ pressure and minimal basal EGJ pressure was found in post-operative as compared with preoperative patients (P < 0.05 and P < 0.001, respectively). Integrated relaxation pressure (IRP) reached higher values in post-operative patients than in pre-operative patients (P < 0.001). Intra-bolus pressure (IBP) was significantly higher (P < 0.05) and contractile front velocity (CFV) was slower (P < 0.01) in post-operative patients than in pre-operative patients. Moreover significant increase of distal contractile integral (DCI) was found in post-operative patients (P < 0.05). Hiatal hernia was detected by HRM in 11 pre-operative patients. Fifteen out of 25 post-operative patients complained of dysphagia. Conclusions Fundoplication restores the antireflux barrier by reinforcing EGJ basal pressures, repairing hiatal hernias, and enhances peristaltic function of the esophagus by increasing DCI. However slight IRP elevation found in post-fundoplication patients may result in bolus pressurization and motility disorders. PMID:27535114

    Gastroesophageal reflux disease (GERD) is often associated with decreased upper gastrointestinal motility, and ghrelin is an appetite-stimulating hormone known to increase gastrointestinal motility. We investigated whether ghrelin signaling is impaired in rats with GERD and studied its involvement in upper gastrointestinal motility. GERD was induced surgically in Wistar rats. Rats were injected intravenously with ghrelin (3 nmol/rat), after which gastric emptying, food intake, gastroduodenal motility, and growth hormone (GH) release were investigated. Furthermore, plasma ghrelin levels and the expression of ghrelin-related genes in the stomach and hypothalamus were examined. In addition, we administered ghrelin to GERD rats treated with rikkunshito, a Kampo medicine, and examined its effects on gastroduodenal motility. GERD rats showed a considerable decrease in gastric emptying, food intake, and antral motility. Ghrelin administration significantly increased gastric emptying, food intake, and antral and duodenal motility in sham-operated rats, but not in GERD rats. The effect of ghrelin on GH release was also attenuated in GERD rats, which had significantly increased plasma ghrelin levels and expression of orexigenic neuropeptide Y/agouti-related peptide mRNA in the hypothalamus. The number of ghrelin-positive cells in the gastric body decreased in GERD rats, but the expression of gastric preproghrelin and GH secretagogue receptor mRNA was not affected. However, when ghrelin was exogenously administered to GERD rats treated with rikkunshito, a significant increase in antral motility was observed. These results suggest that gastrointestinal dysmotility is associated with impaired ghrelin signaling in GERD rats and that rikkunshito restores gastrointestinal motility by improving the ghrelin response.

    Patients with gastroesophageal reflux disease (GERD) present with comorbid complications with implications for healthcare utilization. To date, little is known about the effects of GERD treatment with a proton-pump inhibitor (PPI) on patients’ subsequent healthcare utilization for acute respiratory infections (ARIs). This population-based study compared ARI episodes captured through outpatient visits, one year before and one year after GERD patients received PPI treatment. We used retrospective data from the Longitudinal Health Insurance Database 2005 in Taiwan, comparing 21,486 patients diagnosed with GERD from 2010 to 2012 with 21,486 age-sex matched comparison patients without GERD. Annual ARI episodes represented by ambulatory care visits for ARI (visits during a 7-day period bundled into one episode), were compared between the patient groups during the 1-year period before and after the index date (date of GERD diagnosis for study patients, first ambulatory visit in the same year for their matched comparison counterpart). Multiple regression analysis using a difference-in-difference approach was performed to estimate the adjusted association between GERD treatment and the subsequent annual ARI rate. We found that the mean annual ARI episode rate among GERD patients reduced by 11.4%, from 4.39 before PPI treatment, to 3.89 following treatment (mean change = -0.5 visit, 95% confidence interval (CI) = (-0.64, -0.36)). In Poisson regression analysis, GERD treatment showed an independent association with the annual ARI rate, showing a negative estimate (with p<0.001). The study suggests that GERD treatment with PPIs may help reduce healthcare visits for ARIs, highlighting the importance of treatment-seeking by GERD patients and compliance with treatment.

    BACKGROUND: The aim of this study was to analyse the impact of hiatal hernia repair (HHR) on gastro-oesophageal reflux disease (GERD) in morbidly obese patients with hiatus hernia undergoing laparoscopic sleeve gastrectomy (LSG). MATERIALS AND METHODS: It is a retrospective study involving ten morbidly obese patients with large hiatus hernia diagnosed on pre-operative endoscopy who underwent LSG and simultaneous HHR. The patients were assessed for symptoms of GERD using a Severity symptom score (SS) questionnaire and anti-reflux medications. RESULTS: Of the ten patients, five patients had GERD preoperatively. At the mean follow-up of 11.70 ± 6.07 months after surgery, four patients (80%) showed complete resolution while one patient complained of persistence of symptoms. Endoscopy in this patient revealed resolution of esophagitis indicating that the persistent symptoms were not attributable to reflux. The other five patients without GERD remained free of any symptom attributable to GERD. Thus, in all ten patients, repair of hiatal hernia (HH) during LSG led to either resolution of GERD or prevented any new onset symptom related to GER. CONCLUSION: In morbidly obese patients with HH with or without GERD undergoing LSG, repair of the hiatus hernia helps in amelioration of GERD and prevents any new onset GER. Thus, the presence of HH should not be considered as a contraindication for LSG. PMID:28281472

    Gastroesophageal reflux (GER) is commonly observed in children, particularly during the first year of life. Pharmacological therapy is mostly reserved for symptomatic infants diagnosed with GER disease (GERD), usually as defined in a recent consensus statement. The purpose of the present article was to review the reported adverse effects of pharmacological agents used in the treatment of paediatric GERD. We conducted this review using the electronic journal database Pubmed and Cochrane database systematic reviews using the latest 10-year period (1 January 2003 to 31 December 2012). Our search strategy included the following keywords: omeprazole, esomeprazole, lansoprazole, pantoprazole, rabeprazole, rantidine, cimetidine, famotidine, nizatidine, domperidone, metoclopramide, betanechol, erythromycin, baclofen, alginate. We used Pubmed's own filter of: 'child: birth-18 years'. All full articles were reviewed and we only included randomized controlled trials retrieved from our search. We addressed a summary of our search on a drug-by-drug basis with regard to its mechanism of action and clinical applications, and reviewed all of the adverse effects reported and the safety profile of each drug. Adverse effects have been reported in at least 23% of patients treated with histamine H2 receptor antagonists (H2 RAs) and 34% of those treated with proton pump inhibitors (PPIs), and mostly include headaches, diarrhoea, nausea (H2 RAs and PPIs) and constipation (PPIs). Acid suppression may place immune-deficient infants and children, or those with indwelling catheters, at risk for the development of lower respiratory tract infections and nosocomial sepsis. Prokinetic agents have many adverse effects, without major benefits to support their routine use.

    Douglas, Pamela Sylvia

    2013-04-01

    This paper explores two areas in which the translation of research into practice may be improved in the management of cry-fuss behaviours in the first few months of life. Firstly, babies who cry excessively are often prescribed proton pump inhibitors, despite evidence that gastro-oesophageal reflux disease is very rarely a cause. The inaccuracy of commonly used explanatory mechanisms, the side-effects of acid-suppressive medications, and the failure to identify treatable problems, including feeding difficulty when the diagnosis of 'reflux' is applied, are discussed. Secondly, crying breastfed babies are still prescribed lactase or lactose-free formula, despite evidence that the problem of functional lactose overload is one of breastfeeding management. The mechanisms and management of functional lactose overload are discussed. These two problems of research translation need to be addressed because failure to identify and manage other causes of cry-fuss problems, including feeding difficulty, may have adverse outcomes for a small but significant minority of families.

    Gastroesophageal reflux disease (GERD) results from incompetency of the lower esophageal sphincter that allows the contents of the stomach to reflux into the esophagus, the airways, and the mouth. The disease affects about 10% of the western population and has a profound negative impact on quality of life. The majority of patients are successfully treated with proton-pump inhibitors, but up to 40% have incomplete relief of symptoms even after dose adjustment. The laparoscopic Nissen fundoplication represents the surgical gold standard, but is largely underused because of the level of technical difficulty and the prevalence of side effects. These factors have contributed to the propensity of patients to continue with medical therapy despite inadequate symptom control and complications of the disease. As a consequence, a significant ‘therapy gap’ in the treatment of GERD remains evident in current clinical practice. The LINX® Reflux Management System (Torax Medical, St. Paul, MN, USA) is designed to provide a permanent solution to GERD by augmenting the sphincter barrier with a standardized, reproducible laparoscopic procedure that does not alter gastric anatomy and is easily reversible. Two single-group trials confirmed that a magnetic device designed to augment the lower esophageal sphincter can be safely and effectively implanted using a standard laparoscopic approach. The device decreased esophageal acid exposure, improved reflux symptoms and quality of life, and allowed cessation of proton-pump inhibitors in the majority of patients. PMID:23814607

    Abstract Introduction The frequency of gastroesophageal reflux disease (GERD) is increasing, in part through easy inspection of the upper digestive tract, but especially for a real spread of the disease as a consequence of modernity, lifestyle, incorrect dietary rules, and stress arising from social norms. It is a common chronic gastrointestinal disorder in Europe and the United States. Materials and methods The aim of our study is to highlight a relationship between gastroesophageal reflux disease and salivary pH as evidenced by indicator strips, especially in the outpatient field. Twenty adult subjects (10 males and 10 females) aged between 18 and 50 years (GROUP A)_ were selected. How to control a homogeneous group of 20 patients without GERD, or from any type of allergies (GROUP B) was enlisted. Results This method has provided excellent results showing no difference in the measured values compared with the traditional instrumental measurement. Conclusion Our study has allowed us to observe a strong correlation between the saliva pH, nasal cavities and the interaction between the two districts, and could be the basis for a diagnosis of GERD especially in primary health care clinics and in the initial stage of the disease.

    Abstract Transient receptor potential vanilloid-1 (TRPV1) receptor and proteinase-activated receptor 2 (PAR2) have been implicated in the mechanism of acid-induced inflammation in gastroesophageal reflux disease (GERD). We aimed to evaluate TRPV1 and PAR2 mRNA expression levels in the GERD patients and their relationship with endoscopic findings and reflux symptoms. Sixteen healthy controls, 45 patients with erosive reflux disease (ERD), and 14 nonerosive reflux disease (NERD) patients received endoscopy and completed questionnaires. Quantitative real-time polymerase chain reactions (qPCR) of TRPV1, glial cell line-derived neurotrophic factor (GDNF), nerve growth factor (NGF), PAR2, and interleukin (IL)-8 were performed in the distal esophagus specimen. The levels of TRPV1, GDNF, NGF, PAR2, and IL-8 mRNA expression were highest in the ERD group followed by NERD and control groups and the differences between control and ERD groups were statistically significant. Within the ERD group, patients with grade B in Los Angeles (LA) classification showed significantly higher levels of TRPV1, GDNF, and NGF mRNA expression than those with grade A. Presence of reflux symptoms was associated with significant higher levels of TRPV1, PAR2, and IL-8. Notably not extraesophageal but esophageal reflux symptoms were significantly associated with them. Upregulation of TRPV1 and PAR2 pathways might play a role in the development of distal esophageal inflammation and reflux symptoms. And extraesophageal reflux symptoms might not be associated with these processes. PMID:27512850

    The objective of the present study was to estimate the influence of gastroesophageal reflux disease (GERD) on the pH values in the pharynx and nose. It included 87 patients at the age varying from 18 to 81 years admitted to the Irkutsk-based Railway Clinical Hospital and allocated to four groups. Group 1 was comprised of 25 patients presenting with gastroesophageal reflux disease and chronic rhinosinusitis (CRS), group 2 consisted of 29 patients with CRS in the absence of GERD, group 3 included 22 patients with nasal septum deformations (NSD) and GERD, group 4 included 11 patients with NSD and motor rhinitis without GERD. The control group was formed from 10 volunteers. pH was measured by the contact method with the use ofEkokhim indicator paper. Gastroesophageal reflux disease was diagnosed following the recommendations of the Montreal consensus. It was shown that pH values in the pharynx of the patients with compromised nasal breathing of any origin in combination with GERD were lower than in the absence of GERD and in the healthy volunteers. The study groups did not differ in terms of pH values in the nasal cavity. It is concluded that pH values 4 or lower may serve as the criterion for pharyngo-laryngeal reflux (PLR) concomitant with HERD while pH 5 occurs more frequently in the patients with compromised nasal breathing of any etiology, regardless of the presence or absence of GERD.Disordered nasal breathing of any genesis in the patients presenting with gastroesophageal reflux disease was associated with the feeling of the lump in the throat, congestion of the respiratory tract and the nose, pain in the ears, cardialgia, and irregular heartbeat. It isrecommended to use pH measurements as a criterion for diagnostics of pharyngo-laryngeal reflux in the patients presenting with gastroesophageal reflux disease.

A cross-sectional study was conducted in 2012, which included a population-based sample of 817 individuals (≥18 years) residing in Tirana, the Albanian capital (333 men; overall mean age: 50.2 ± 18.7 years; overall response rate: 82%). Assessment of gastroesophageal reflux disease was based on Montreal definition. Participants were interviewed about their dietary patterns, which in the analysis was dichotomized into: predominantly Mediterranean (frequent consumption of composite/traditional dishes, fresh fruit and vegetables, olive oil, and fish) versus largely non-Mediterranean (frequent consumption of red meat, fried food, sweets, and junk/fast food). Logistic regression was used to assess the association of gastroesophageal reflux disease with the dietary patterns. Irrespective of demographic and socioeconomic characteristics and lifestyle factors including eating habits (meal regularity, eating rate, and meal-to-sleep interval), employment of a non-Mediterranean diet was positively related to gastroesophageal reflux disease risk (fully adjusted odds ratio = 2.3, 95% confidence interval = 1.2-4.5). Our findings point to a beneficial effect of a Mediterranean diet in the occurrence of gastroesophageal reflux disease in transitional Albania. Findings from this study should be confirmed and expanded further in prospective studies in Albania and in other Mediterranean countries.

    Gastroesophageal reflux has been incriminated as a factor-inhibiting acquisition of esophageal speech after laryngectomy. Fourteen proficient esophageal speakers and 10 nonproficient speakers underwent esophageal manometry, esophageal pH probe testing, and Bernstein acid perfusion testing. Additionally, 175 laryngectomized members of Lost Chord Clubs answered mailed questionnaires about the frequency of reflux symptoms. Nonproficient and proficient esophageal speakers had a similar frequency of gastroesophageal reflux by pH probe testing, esophageal mucosal acid sensitivity by Bernstein testing, lower esophageal sphincter pressures, and gastroesophageal reflux symptoms. Gastroesophageal reflux does not appear to be a major factor in preventing esophageal speech.

    We report 4 patients with upper urinary tract (UUT) obstruction requiring ureteric reimplantation at 1, 7, 28, and 63 months after dextranomer/hyaluronic acid copolymer (Dx/HA) injection for vesicoureteric reflux. Histopathologic evaluation of ureteric segments revealed extensive foreign body formation in all cases. We conclude that UUT obstruction is a rare but serious complication after Dx/HA injection that can occur even years after surgery. The incidence of delayed-onset UUT obstruction may be higher than previously noted. Long-term follow-up and a critical reappraisal of the method are needed to assess the late sequelae of Dx/HA injection therapy for vesicoureteric reflux.

    Endoscopic treatment for vesicoureteral reflux (VUR) has become an established alternative to long-term antibiotic prophylaxis and ureteral reimplantation. We present the outcome of endoscopic treatment with dextranomer/hyaluronic acid copolymer (Deflux) for VUR in children by a single surgeon at our institute from October 2003 to October 2009. We reviewed the cases of 150 patients (total 239 ureters), 56 girls (37%) and 94 boys (63%), with a mean age of 2.2 years and a median followup of 2.5 years (range 3-68 months). Among the 239 ureters treated, 67.4% (161/239) were cured with a single injection, and a second and third injection raised the cure rate to 86.6% (207/239) and 88.3% (211/239), respectively. None had postoperative ureteral obstruction.

    Purpose Gastroesophageal reflux disease (GERD) occurs in pediatric patients when reflux of gastric contents presents with troublesome symptoms. The present study compared the effects of omeprazole and ranitidine for the treatment of symptomatic GERD in infants of 2-12 months. Methods This study was a clinical randomized double-blind trial and parallel-group comparison of omeprazole and ranitidine performed at Children Training Hospital in Tabriz, Iran. Patients received a standard treatment for 2 weeks. After 2 weeks, the patients with persistent symptoms were enrolled in this randomized study. Results We enrolled 76 patients in the present study and excluded 16 patients. Thirty patients each were included in group A (ranitidine) and in group B (omeprazole). GERD symptom score for groups A and B was 47.17±5.62 and 51.93±5.42, respectively, with a P value of 0.54, before the treatment and 2.47±0.58 and 2.43±1.15, respectively, after the treatment (P=0.98). No statistically significant differences were found between ranitidine and omeprazole in their efficacy for the treatment of GERD. Conclusion The safety and efficacy of ranitidine and omeprazole have been demonstrated in infants. Both groups of infants showed a statistically significant decrease in the score of clinical variables after the treatment. PMID:27279887

    About one-third of patients with suspected gastro-oesophageal reflux disease (GERD) do not respond symptomatically to proton pump inhibitors (PPIs). Many of these patients do not suffer from GERD, but may have underlying functional heartburn or atypical chest pain. Other causes of failure to respond to PPIs include inadequate acid suppression, non-acid reflux, oesophageal hypersensitivity, oesophageal dysmotility and psychological comorbidities. Functional oesophageal tests can exclude cardiac and structural causes, as well as help to confi rm or exclude GERD. The use of PPIs should only be continued in the presence of acid reflux or oesophageal hypersensitivity for acid reflux-related events that is proven on functional oesophageal tests. PMID:27779277

    Esophagitis was induced in rats within 3 h by ligating both the pylorus and transitional region between the forestomach and glandular portion under ether anesthesia. This esophageal injury was prevented by the administration of acid suppressants and antipepsin drug and aggravated by exogenous pepsin. Damage was also aggravated by pretreatment with indomethacin and the selective COX-1 but not COX-2 inhibitor, whereas PGE2 showed a biphasic effect depending on the dose; a protection at low doses, and an aggravation at high doses, with both being mediated by EP1 receptors. Various amino acids also affected this esophagitis in different ways; L-alanine and L-glutamine had a deleterious effect, while L-arginine and glycine were highly protective, both due to yet unidentified mechanisms. It is assumed that acid/pepsin plays a major pathogenic role in this model of esophagitis; PGs derived from COX-1 are involved in mucosal defense of the esophagus; and some amino acids are protective against esophagitis. These findings also suggest a novel therapeutic approach in the treatment of esophagitis, in addition to acid suppressant therapy. The model introduced may be useful to test the protective effects of drugs on esophagitis and investigate the mucosal defense mechanism in the esophagus.

    Abstract Rationale: The patient had symptoms of GERD and the reflux even caused the symptom of cough. Gaining weight is a risk factor for the treatment of reflux as it could exacerbated symptoms of reflux and the drug treatment is not effective. Surgical intervention becomes necessary when there is failure following conservative medical therapy or the patient. Patient concerns: The patient was not satisfied with the drug treatment. Diagnoses: Superior mesenteric artery syndrome, gastroesophageal reflux disease. Interventions: Laparoscopic Toupet fundoplication with duodenojejunostomy. Outcomes: The patient discharged from hospital 10 days after surgery without any postoperative complication. The patient achieved complete relief of symptoms and discontinuation of drug. Lessons subsections: Superior mesenteric artery (SMA) syndrome may manifest the symptoms of GERD such as heartburn, acid reflux and cough. It is necessary to complete examination to exclude superior mesenteric artery syndrome for these patients. Laparoscopic fundoplication with duodenojejunostomy provided an effective treatment for patients who failed drug treatment. PMID:28099334

    This study presents a simplified approach for size-controlled synthesis of manganese oxide octahedral molecular sieve (OMS-2) nanowires using potassium permanganate (KMnO4) and different inorganic acids (HCl, HNO3, and H2SO4) under reflux conditions. The morphology and nanostructure of the synthesized products are characterized by X-ray diffraction, Ar adsorption, and electron microscopy analysis, in order to elucidate the controlling effects of acid concentration and type as well as the formation mechanism of OMS-2 nanowires. The concentration of inorganic acid is a crucial factor controlling the phase of the synthesized products. OMS-2 nanowires are obtained with HCl at the concentration ≥0.96 mol/L or with HNO3 and H2SO4 at the concentrations ≥0.72 mol/L. Differently, the type of inorganic acid effectively determines the particle size of OMS-2 nanowires. When the acid is changed from HCl to HNO3 and H2SO4 in the reflux system, the average length of OMS-2 declines significantly by 60-70% (1104-442 and 339 nm), with minor decreased in the average width (43-39 and 34 nm). The formation of OMS-2 nanowires under reflux conditions with KMnO4 and inorganic acids involves a two-step process, i.e., the initial formation of layered manganese oxides, and subsequent transformation to OMS-2 via a dissolution-recrystallization process under acidic conditions. The proposed reflux route provides an alternative approach for synthesizing OMS-2 nanowires as well as other porous nano-crystalline OMS materials.

    At the patients with gastroesophageal reflux disease on background of chronic obstructive lung disease before treatment was detected the increase products of lipids peroxidation (LPO) such as malon dialdegide (MDA), dien's conjugates (DC) in the serum blood. The decline of enzymes activity of the antioxydant system (AOS)--catalase (CT) and superoxiddismutase (SOD) was marked. At treatment the generally accepted facilities was marked decline of MDA, DK and KT and SOD activity. But their level was differed from a norm. It testifies to the maintainance of disbalance of LPO-AOS and expedience of preparations with antioxydant activity application.

    Although gastroesophageal reflux disease is not as common in Asia as in western countries, the prevalence has increased substantially during the past decade. Gastroesophageal reflux disease is associated with considerable reductions in subjective well-being and work productivity, as well as increased healthcare use. Proton pump inhibitors (PPIs) are currently the most effective treatment for gastroesophageal reflux disease. However, there are limitations associated with these drugs in terms of partial and non-response. Dexlansoprazole is the first PPI with a dual delayed release formulation designed to provide 2 separate releases of medication to extend the duration of effective plasma drug concentration. Dexlansoprazole has been shown to be effective for healing of erosive esophagitis, and to improve subjective well-being by controlling 24-hour symptoms. Dexlansoprazole has also been shown to achieve good plasma concentration regardless of administration with food, providing flexible dosing. Studies in healthy volunteers showed no clinically important effects on exposure to the active metabolite of clopidogrel or clopidogrel-induced platelet inhibition, with no dose adjustment of clopidogrel necessary when coprescribed. This review discusses the role of the new generation PPI, dexlansoprazole, in the treatment of gastroesophageal reflux disease in Asia.

    Symptomatic differences and the impact of gastroesophageal reflux disease (GERD) have not been clarified in patients with asthma and chronic obstructive pulmonary disease (COPD). The purpose of this study is to assess the differences of GERD symptoms among asthma, COPD, and disease control patients, and determine the impact of GERD symptoms on exacerbation of asthma or COPD by using a new questionnaire for GERD. A total of 120 subjects underwent assessment with the frequency scale for the symptoms of GERD (FSSG) questionnaire, including 40 age-matched patients in each of the asthma, COPD, and disease control groups. Asthma and control patients had more regurgitation-related symptoms than COPD patients (p<0.05), while COPD patients had more dysmotility-related symptoms than asthma patients (p<0.01) or disease control patients (p<0.01). The most distinctive symptom of asthma patients with GERD was an unusual sensation in the throat, while bloated stomach was the chief symptom of COPD patients with GERD, and these symptoms were associated with disease exacerbations. The presence of GERD diagnosed by the total score of FSSG influences the exacerbation of COPD. GERD symptoms differed between asthma and COPD patients, and the presence of GERD diagnosed by the FSSG influences the exacerbation of COPD. PMID:22448100

    Some patients with gastro-oesophageal reflux disease (GORD) experience symptoms despite proton pump inhibitor (PPI) treatment. In the early years of their availability, these drugs were thought to be a highly effective treatment for GORD and realisation that symptom relief was often incomplete came as a disappointment. This review considers the evolution of thinking with the aid of the Gartner hype cycle - a graphical depiction of the process of innovation, evolution and adoption of new technologies. Acknowledging that over-simplistic concepts of GORD have been largely responsible for inflated expectations of PPI therapy is an important step forward in establishing how patients with persistent symptoms, despite PPIs, should be assessed and treated.

    Objective Sleeve gastrectomy is the fastest growing surgical procedure to treat obesity in the world but it may cause or worsen gastroesophageal reflux disease. This article originally aimed to describe the addition of anti-reflux procedures (removal of periesophageal fats pads, hiatoplasty, a small plication and fixation of the gastric remnant in position) to the usual sleeve gastrectomy and to report early and late results. Methods Eighty-eight obese patients that also presented symptoms of gastroesophageal reflux disease were submitted to sleeve gastrectomy with anti-reflux procedures. Fifty of them were also submitted to a transit bipartition. The weight loss of these patients was compared to consecutive 360 patients previously submitted to the usual sleeve gastrectomy and to 1,140 submitted to sleeve gastrectomy + transit bipartition. Gastroesophageal reflux disease symptoms were specifically inquired in all anti-reflux sleeve gastrectomy patients and compared to the results of the same questionnaire applied to 50 sleeve gastrectomy patients and 60 sleeve gastrectomy + transit bipartition patients that also presented preoperative symptoms of gastroesophageal reflux disease. Results In terms of weight loss, excess of body mass index loss percentage after anti-reflux sleeve gastrectomy is not inferior to the usual sleeve gastrectomy and anti-reflux sleeve gastrectomy + transit bipartition is not inferior to sleeve gastrectomy + transit bipartition. Anti-reflux sleeve gastrectomy did not add morbidity but significantly diminished gastroesophageal reflux disease symptoms and the use of proton pump inhibitors to treat this condition. Conclusion The addition of anti-reflux procedures, such as hiatoplasty and cardioplication, to the usual sleeve gastrectomy did not add morbidity neither worsened the weight loss but significantly reduced the occurrence of gastroesophageal reflux disease symptoms as well as the use of proton pump inhibitors.

    2017-01-01

    The present study was conducted to evaluate both antioxidant and anti-inflammatory activity of Banhasasim-tang (BHSST) on chronic acid reflux esophagitis (CRE) model. Rat CRE model was established operatively and then treated with BHSST (1 g/kg body weight per day) for 15 days Esophageal pathological changes were analyzed using macroscopic examination and hematoxylin/eosin staining. The antioxidant and inflammatory protein levels were determined using Western blotting. The administration of BHSST significantly reduced both the overexpression of serum reactive oxygen species (ROS) and an excessive formation of thiobarbituric acid-reactive substances (TBARS) in esophagus tissue. Thus, the severity of esophageal ulcer was lower in BHSST treated rats than control rats on the gross and histological evaluation. Nuclear factor-erythroid 2-related factor 2 (Nrf2) led to the upregulation of antioxidant enzyme including SOD, GPx-1/2, and HO-1 by binding to antioxidant response element (ARE). Moreover, BHSST administration markedly reduced the expression of inflammatory proteins through mitogen-activated protein kinase- (MAPK-) related signaling pathways and decreased significantly the protein expressions of inflammatory mediators and cytokines by inhibition of nuclear factor-kappa B (NF-κB) activation. Taken together, these results support the fact that BHSST administration can suppress the development of esophageal mucosal ulcer via regulating inflammation through the activation of the antioxidant pathway.

    Integrating evidence-based clinical practice guidelines on gastroesophageal reflux disease into medical practice is of prime importance in Latin America, given its high prevalence in this region. The aim of this project was to implement and assess an educational intervention on gastroesophageal reflux disease, aimed at primary care physicians in Latin America, with contents based on current clinical guidelines. The course included initial activities, whether face-to-face or through distance learning, and a 2-month period of Internet study and interaction. A pilot test was carried out in Uruguay, which was then repeated in 5 countries (Mexico, Colombia, Venezuela, Argentina and again in Uruguay). A global template was designed, which was then adapted to each of the countries: this was done with the participation of local institutions and leaders. Local credits were given for recertification. Participation was free. Of 3,110 physicians invited to participate, 1,143 (36.8%) started the course. Of these, 587 (51.4%) accessed at least half the contents of the course and 785 (68.7%) took part in the clinical discussions. A total of 338 (29.6%) completed all the requirements of the course and received a certificate. Among physicians who took both the pre- and post-intervention knowledge tests, scores improved from 60 to 80% (P<.001). Ninety-two percent of planned changes in clinical practice were related to the pedagogic aims of the course. In conclusion, a multifaceted, 2-phase continuing education course was successfully imparted in Latin America, with an overall design that was adapted to each country. Determination of specific needs and the participation of national experts were fundamental to the success of the course.

    AIM: To evaluate the efficacy of lower esophageal sphincter (LES)-electrical stimulation therapy (EST) in a subgroup of patients that reported only partial response to proton pump inhibitors (PPIs) therapy, compared to a group of patient with complete response. METHODS: Bipolar stitch electrodes were laparoscopically placed in the LES and connected to an implantable pulse generator (EndoStim BV, the Hague, the Netherlands), placed subcutaneously in the anterior abdominal wall. Stimulation at 20 Hz, 215 μsec, 3-8 mAmp in 30 min sessions was delivered starting on day 1 post-implant. Patients were evaluated using gastroesophageal reflux disease (GERD)-HRQL, symptom diaries; esophageal pH and esophageal manometry before and up to 24 mo after therapy and results were compared between partial and complete responders. RESULTS: Twenty-three patients with GERD on LES-EST were enrolled and received continuous per-protocol stimulation through 12 mo and 21 patients completed 24 mo of therapy. Of the 23 patients, 16 (8 male, mean age 52.1 ± 12 years) had incomplete response to PPIs prior to LES-EST, while 7 patients (5 male, mean age 52.7 ± 4.7) had complete response to PPIs. In the sub-group with incomplete response to PPIs, median (IQR) composite GERD-HRQL score improved significantly from 9.5 (9.0-10.0) at baseline on-PPI and 24.0 (20.8-26.3) at baseline off-PPI to 2.5 (0.0-4.0) at 12-mo and 0.0 (0.0-2.5) at 24-mo follow-up (P < 0.05 compared to on-and off-PPI at baseline). Median (IQR) % 24-h esophageal pH < 4.0 at baseline in this sub-group improved significantly from 9.8% (7.8-11.5) at baseline to 3.0% (1.9-6.3) at 12 mo (P < 0.001) and 4.6% (2.0-5.8) at 24 mo follow-up (P < 0.01). At their 24-mo follow-up, 9/11 patients in this sub-group were completely free of PPI use. These results were comparable to the sub-group that reported complete response to PPI therapy at baseline. No unanticipated implantation or stimulation-related adverse events, or any untoward sensation

    Although gastroesophageal reflux disease (GERD) has been reported to coexist with chronic rhinosinusitis (CRS), it remains controversial whether it increases risk of CRS in adults. This study accesses risk of CRS in adults with newly diagnosed GERD. We identified 15,807 adult patients with newly diagnosed GERD from Taiwan's National Health Insurance Research Database for January 1, 2006 to December 31, 2009. We also randomly selected 47,421 subjects without this disease and matched them with patients by age, sex, index year, and comorbidity to create a control cohort. A Cox proportional hazards model was conducted to estimate the development of CRS, including CRS without nasal polyps and CRS with nasal polyps. Subjects were followed for a median of 2.12 years. In total, CRS developed in 964 (1.52%) of the subjects: 406 patients with GERD (2.57%) and 558 without it (1.18%). After adjustment, those with GERD were found to have a 2.36 times greater risk of CRS (95% confidence interval = 2.08-2.68; P < .001). Risk of this CRS without nasal polyps was higher than the disease with polyps (adjusted hazard ratio: 2.48 vs 1.85). The individuals with GERD in this study were at significantly greater risk of CRS, most often without nasal polyps.

    Background Symptoms of heartburn has an impact on health-related quality of life (HRQL). When a questionnaire is translated into a new language, a linguistic validation is necessary but not sufficient unless the psychometric characteristics have been verified. The aim is to document the psychometric characteristics of the German translation of the Gastrointestinal Symptom Rating Scale (GSRS) and Quality of Life in Reflux and Dyspepsia (QOLRAD) questionnaire. Methods 142 patients with symptoms of heartburn (Age: M = 47.5, ± 14.6; Males = 44.4%) completed the German translation of GSRS, the QOLRAD, the Short-Form-36 (SF-36) and the Hospital Anxiety and Depression (HAD) scale. Results The internal consistency reliability of GSRS ranged from 0.53–0.91 and of QOLRAD from 0.90–0.94, respectively. The test-retest reliability of GSRS ranged from 0.49–0.73 and of QOLRAD from 0.70–0.84. The relevant domains of the GSRS and QOLRAD domain scores significantly correlated. GSRS domains of Abdominal Pain and Constipation correlated (negatively) with most of the domains of the SF-36. The relevant QOLRAD domains significantly correlated with all SF-36 domains. Conclusions The psychometric characteristics of the German translation of GSRS and QOLRAD were found to be good, with satisfactory reliability and validity. The reliability of the GSRS Abdominal Pain domain was moderate. PMID:14613560

Több megfigyelés szerint a gastrooesophagealis refluxbetegség (GERB) súlyossága és fennállásának ideje fontos patogenetikai tényező a Barrett-nyelőcső kialakulásában. Betegek és módszer: Retrospektív vizsgálatunkban 2001–2008 között laparoscopos Nissen szerinti antireflux műtéten átesett 176 refluxbeteg és 78 BE-vel szövődött beteg praeoperativ kivizsgálási eredményeit (tünetek, 24 órás pH-metria, nyelőcső-manometria, Bilitec) és kezelésük hatékonyságát hasonlítottuk össze. Eredmények: A betegcsoportok nem különböztek demográfiai jellemzőikben, és refluxos tüneteik időtartama is azonos hosszúságú volt. A betegek mindkét csoportban átlagosan másfél éves (19,87 vs. 19,20 hónap) eredménytelen gyógyszeres (protonpumpagátló) kezelés után kerültek műtétre. A praeoperativ functionalis vizsgálatok a BE-csoportban súlyosabb savas reflux meglétét igazolták (DeMeester-score 18,9 vs. 41,9, p < 0,001). Ugyanakkor a manometria – bár alátámasztotta az alsó nyelőcsősphincter (LES) károsodását – nem mutatott különbséget a két csoport között (12,10 vs. 12,57 Hgmm, p = 0,892). A laparoscopos antireflux műtéteknek halálozása nem volt, két esetben történt conversio súlyos adhaesiók, illetve lépsérülés miatt. Három hónappal a műtétet követően a Visick-score alapján mindkét csoportban jelentősen csökkentek vagy megszűntek a refluxos tünetek (az I. csoportban a betegek 73%-ánál, a II. csoportban a betegek 81%-ánál), javult a LES működése (17,58 és 18,70 Hgmm), és csökkent a savas reflux gyakorisága és expositiója (DeMeester-score 7,73 és 12,72). Következtetés: A károsodott LES incompetens működésével párhuzamosan jelentkező kóros savas reflux súlyossága potencírozza a gastrooesophagealis junctióban (GEJ) megjelenő gyullad

    Gastroesophageal reflux disease is the most common upper gastroenterology disorder in the US. It is associated with a variety of complications and significantly impacts quality of life. Proton pump inhibitors are the most effective treatment. Dexlansoprazole modified release (MR) is a proton pump inhibitor that employs a novel release formulation that prolongs its absorption and allows for more flexibility in dosing. Dexlansoprazole MR can be dosed without regard to food intake or time of day, and once-daily dosing may replace twice-daily dosing of other agents. Dexlansoprazole MR is effective for healing and maintenance of erosive esophagitis, and for the treatment of nonerosive disease, including nocturnal gastroesophageal reflux disease. Dexlansoprazole MR is safe and well tolerated, and can improve quality of life.

    The epidemic of gastroesophageal reflux disease (GERD) in industrialized nations is currently spreading to less-developed ones, with more than half of the patients having symptomatic or mild erosive GERD. The long-term management of GERD has been dominated by daily maintenance treatment with proton pump inhibitors (PPI) to prevent relapse. It is common, however, for many patients with mild disease and infrequent symptom relapses to use a PPI only when symptoms demand. Patients with symptomatic or mild erosive GERD are therefore ideal for on-demand or intermittent treatment. The efficacy of such a strategy of intermittent treatment, or treatment of symptoms on demand, has recently been evaluated in four randomized controlled studies. These trials demonstrate that such therapeutic strategies reduce symptoms, improve quality of life, and are cost effective. In clinical practice, the author has found these treatment strategies suitable for approximately 60% of newly diagnosed patients with GERD for the long-term management of symptomatic GERD of mild or moderate severity.

    Modified Banxia Xiexin decoction (MBXD) is a classical Chinese herbal formula in treating gastroesophageal reflux disease (GERD) for long time, but the efficacy of it is still controversial. This study is to evaluate the efficacy and safety of MBXD for the treatment of GERD in adults. The search strategy was carried out for publications in seven electronic databases. RevMan software version 5.3 and the Cochrane Collaboration's risk of bias tool were performed for this review. Twelve RCTs were included for the analysis. The results of overall clinical efficacy and efficacy under gastroscope demonstrated that MBXD was superior to conventional western medicine. Meanwhile, the results of subgroup analysis showed clinical heterogeneity between the two groups. However, there was no statistically significant difference in acid regurgitation between the two groups. But in the improvement of heartburn and sternalgia, the results showed statistically significant differences for the comparison between two groups. In addition, the adverse reactions of the experiment groups were not different from those of the control groups. This systematic review indicates that MBXD may have potential effects on the treatment of patients with GERD. But because the evidence of methodological quality and sample sizes is weak, further standardized researches are required. PMID:28298938

    This large-scale, controlled cohort study estimated the risks of lung cancer in patients with gastro-esophageal reflux disease (GERD) in Taiwan. We conducted this population-based study using data from the National Health Insurance Research Database of Taiwan during the period from 1997 to 2010. Patients with GERD were diagnosed using endoscopy, and controls were matched to patients with GERD at a ratio of 1:4. We identified 15,412 patients with GERD and 60,957 controls. Compared with the controls, the patients with GERD had higher rates of osteoporosis, diabetes mellitus, asthma, chronic obstructive pulmonary disease, pneumonia, bronchiectasis, depression, anxiety, hypertension, dyslipidemia, chronic liver disease, congestive heart failure, atrial fibrillation, stroke, chronic kidney disease, and coronary artery disease (all P < .05). A total of 85 patients had lung cancer among patients with GERD during the follow-up of 42,555 person-years, and the rate of lung cancer was 0.0020 per person-year. By contrast, 232 patients had lung cancer among patients without GERD during the follow-up of 175,319 person-years, and the rate of lung cancer was 0.0013 per person-year. By using stepwise Cox regression model, the overall incidence of lung cancer remained significantly higher in the patients with GERD than in the controls (hazard ratio, 1.53; 95% CI [1.19–1.98]). The cumulative incidence of lung cancer was higher in the patients with GERD than in the controls (P = .0012). In conclusion, our large population-based cohort study provides evidence that GERD may increase the risk of lung cancer in Asians. PMID:28028458

    Background The impact of gastroesophageal reflux disease (GERD) on the daily lives of patients managed in primary care is not well known. We report the burden of GERD in a large population of patients managed in primary care, in terms of symptoms and impact on patients' daily lives. Methods RANGE (Retrospective ANalysis of GERD) was an observational study that was conducted at 134 primary care sites across six European countries. All adult subjects who had consulted their primary care physician (PCP) during a 4-month identification period were screened retrospectively and those consulting at least once for GERD-related reasons were identified. From this population, a random sample of patients was selected to enter the study and attended a follow-up appointment, during which the Reflux Disease Questionnaire (RDQ), the GERD Impact Scale (GIS) and an extra-esophageal symptoms questionnaire were self-administered. Based on medical records, data were collected on demographics, history of GERD, its diagnostic work-up and therapy. Results Over the 4-month identification period, 373,610 subjects consulted their PCP and 12,815 (3.4%) did so for GERD-related reasons. From 2678 patients interviewed (approximately 75% of whom reported taking medication for GERD symptoms), symptom recurrence following a period of remission was the most common reason for consultation (35%). At the follow-up visit, with regard to RDQ items (score range 0–5, where high score = worse status), mean Heartburn dimension scores ranged from 0.8 (Sweden) to 1.2 (UK) and mean Regurgitation dimension scores ranged from 1.0 (Norway) to 1.4 (Germany). Mean overall GIS scores (range 1–4, where low score = worse status) ranged from 3.3 (Germany) to 3.5 (Spain). With regard to extra-esophageal symptoms, sleep disturbance was common in all countries in terms of both frequency and intensity. Conclusion In this large European observational study, GERD was associated with a substantial impact on the daily lives

    Objective Proton pump inhibitors are frequently administered on clinical symptoms in neonates but benefit remains controversial. Clinical trials validating omeprazole dosage in neonates are limited. The objective of this trial was to determine the minimum effective dose (MED) of omeprazole to treat pathological acid reflux in neonates using reflux index as surrogate marker. Design Double blind dose-finding trial with continual reassessment method of individual dose administration using a Bayesian approach, aiming to select drug dose as close as possible to the predefined target level of efficacy (with a credibility interval of 95%). Setting Neonatal Intensive Care unit of the Robert Debré University Hospital in Paris, France. Patients Neonates with a postmenstrual age ≥ 35 weeks and a pathologic 24-hour intra-esophageal pH monitoring defined by a reflux index ≥ 5% over 24 hours were considered for participation. Recruitment was stratified to 3 groups according to gestational age at birth. Intervention Five preselected doses of oral omeprazole from 1 to 3 mg/kg/day. Main outcome measures Primary outcome, measured at 35 weeks postmenstrual age or more, was a reflux index <5% during the 24-h pH monitoring registered 72±24 hours after omeprazole initiation. Results Fifty-four neonates with a reflux index ranging from 5.06 to 27.7% were included. Median age was 37.5 days and median postmenstrual age was 36 weeks. In neonates born at less than 32 weeks of GA (n = 30), the MED was 2.5mg/kg/day with an estimated mean posterior probability of success of 97.7% (95% credibility interval: 90.3–99.7%). The MED was 1mg/kg/day for neonates born at more than 32 GA (n = 24). Conclusions Omeprazole is extensively prescribed on clinical symptoms but efficacy is not demonstrated while safety concerns do exist. When treatment is required, the daily dose needs to be validated in preterm and term neonates. Optimal doses of omeprazole to increase gastric pH and decrease reflux

    Inhibition of gastric acid secretion is the mainstay of the treatment of gastroesophageal reflux disease and peptic ulceration; therapies to inhibit acid are among the best-selling drugs worldwide. Highly effective agents targeting the histamine H2 receptor were first identified in the 1970s. These were followed by the development of irreversible inhibitors of the parietal cell hydrogen-potassium ATPase (the proton pump inhibitors) that inhibit acid secretion much more effectively. Reviewed here are the chemistry, biological targets and pharmacology of these drugs, with reference to their current and evolving clinical utilities. Future directions in the development of acid inhibitory drugs include modifications of current agents and the emergence of a novel class of agents, the acid pump antagonists. PMID:17928953

    Introduction: Various bulking agents are available for vesicoureteral reflux (VUR) endoscopic treatment, but their inconsistent success rates and costs are concerns for urologists. Recently, polyacrylamide hydrogel (PAHG) has been shown to have a good overall success rate, which seems comparable to dextranomer hyaluronic acid (Dx/HA), currently the most popular bulking agent. Our objective was to compare the short-term success rate of PAHG and Dx/HA for VUR endoscopic treatment in children. Methods: We performed a prospective non-randomized study using PAHG and Dx/HA to treat VUR grades I to IV in pediatric patients. All patients underwent endoscopic sub-ureteric injection of PAHG or Dx/HA, using the double-HIT technique, followed by a 3-month postoperative renal ultrasound and voiding cystourethrogram. Treatment success was defined as the absence of de novo or worsening hydronephrosis and absence of VUR. Results: A total of 90 pediatric patients underwent an endoscopic injection: 45 patients (78 ureters) with PAHG and 45 patients (71 ureters) with Dx/HA. The mean injected volume of PAHG and Dx/HA was 1.1 mL and 1.0 mL, respectively. The overall success rate 3 months after a single treatment was 73.1% for PAHG and 77.5% for Dx/HA. Postoperatively, 1 patient in each group presented with acute pyelonephritis and 2 patients in the Dx/HA group developed symptomatic ureteral obstruction. Conclusion: Success rates of PAGH and Dx/HA in endoscopic injections for VUR treatment were comparable. The rate of resolution obtained with Dx/HA was equivalent to those previously published. The lower cost of PAHG makes it an interesting option. PMID:26225173

    Objective Metabolic syndrome and dental erosion have been demonstrated to correlate with gastroesophageal acid reflux disease (GERD), while periodontitis has been reported to have a positive relationship with metabolic syndrome. However, no correlation between periodontitis and GERD has yet been reported. We therefore investigated the relationship between periodontitis and GERD. Methods The subjects consisted of 280 individuals who visited the Health Center for a detailed medical checkup examination. Each underwent upper endoscopy and periodontitis examinations, with the latter performed by measuring the concentrations of lactate dehydrogenase and hemoglobin in saliva. The subjects were divided into those with positive and negative periodontitis findings, and the prevalence rates of endoscopically proven reflux esophagitis, dyslipidemia, hypertension, and hyperglycemia were compared. Results The number of subjects positive for periodontitis was 93, while 187 had negative findings. The prevalence of reflux esophagitis was not different between the positive and negative groups (8.6% vs. 8.0%). In addition, a multiple logistic regression analysis did not identify a positive relationship between the presence of periodontitis and reflux esophagitis. On the other hand, dyslipidemia and hypertension were more frequently observed in the subjects that were positive for periodontitis. Conclusion We did not find an association between periodontitis and reflux esophagitis in the present study. On the other hand, the presence of periodontitis was found to correlate with hypertension and dyslipidemia.

    Purpose Laparoscopic fundoplication is considered the standard surgical treatment for gastroesophageal reflux disease (GERD) in Western countries. However, some patients experience poor surgical outcomes with this procedure. The study aimed to identify the predictive factors of the surgical outcomes of laparoscopic Nissen fundoplication for the treatment of Korean GERD patients. Methods Sixty-one patients with GERD were treated using laparoscopic Nissen fundoplication between November 2012 and February 2015. Symptom control rates were compared according to clinical and surgical factors to identify predictive factors of successful surgical outcomes. Results Thirty-five men and 26 women were enrolled. Preoperatively, typical symptoms were present in 60 patients (98%), while atypical symptoms were present in 40 patients (66%). Postoperatively, typical symptoms were controlled in 51 of 60 patients (85.0%), while atypical symptoms were controlled in 33 of 40 patients (82.5%). Overall, at 6 months postsurgery, 54 (88.5%) reported some resolution of GERD symptoms, with 48 (78.7%) achieving complete control. Patients who exhibited a good response to proton pump inhibitor therapy had a significantly greater rate of complete symptom control (P = 0.035). Conclusion Laparoscopic fundoplication is effective for controlling GERD symptoms. Response to preoperative proton pump inhibitor was a predictor of successful outcome. PMID:28382290

    ABSTRACT Purpose Subureteral injection of bulking agents in the endoscopic treatment of vesicoureteral reflux is widely accepted therapy with high success rates. Although the grade of vesicoureteric reflux and experience of surgeon is the mainstay of this success, the characteristics of augmenting substances may have an effect particularly in the long term. In this retrospective study, we aimed to evaluate the clinical outcomes of the endoscopic treatment of vesicoureteric reflux (VUR) with two different bulking agents: Dextranomer/hyaluronic acid copolymer (Dx/HA) and Polyacrylate polyalcohol copolymer (PPC). Materials and Methods A total 80 patients (49 girls and 31 boys) aged 1-12 years (mean age 5.3 years) underwent endoscopic subureteral injection for correction of VUR last six years. The patients were assigned to two groups: subureteral injections of Dx/HA (45 patients and 57 ureters) and PPC (35 patients and 45 ureters). VUR was grade II in 27 ureters, grade III in 35, grade IV in 22 and grade V in 18 ureters. Results VUR was resolved in 38 (66.6%) of 57 ureters and this equates to VUR correction in 33 (73.3%) of the 45 patients in Dx/HA group. In PPC group, overall success rate was 88.8% (of 40 in 45 ureters). Thus, Thus, this equates to VUR correction in 31 (88.5%) of the 35 patients. Conclusions Our short term data show that two different bulking agent injections provide a high level of reflux resolution and this study revealed that success rate of PPC was significantly higher than Dx/HA with less material.

    Data are limited regarding the role of proteinase-activated receptor-2 (PAR-2) in the esophageal mucosa in gastroesophageal reflux disease (GERD) patients. Our aim was to study PAR-2 expression and its relationship with different GERD-related clinical and pathologic parameters. Histomorphologic alterations in eosophageal mucosa in nonerosive reflux disease (NERD) and erosive reflux disease (ERD) were also, evaluated. Endoscopic biopsies of the esophageal mucosa were obtained from 94 GERD patients and 20 participants for histopathologic analysis and PAR-2 immunohistochemical staining. The present study demonstrated significantly higher PAR-2 expression in GERD patients compared with control, whereas no significant differences were seen between NERD and ERD groups. PAR-2 expression significantly correlated with histologic score (r=0.572, P<0.001) and severity of heartburn (r=0.541, P<0.001). PAR-2 expression was significantly associated with basal cell hyperplasia, and dilated intercellular spaces and inflammatory cell count (P<0.05). Histologic analysis revealed GERD-related histomorphologic alterations in the esophageal mucosa of GERD patients with significant differences (P<0.05) among groups. Total histologic score was significantly correlated with heartburn (r=0.299, P=0.025) and endoscopic severity (r=0.359, P=0.027) in NERD and ERD patients, respectively. Taken together, this study provides evidence for the major role of PAR-2 in the pathogenesis of GERD and GERD-associated mucosal alterations.

    Chest pain experienced by patients with coronary artery disease can be partly due to gastroesophageal reflux-induced chest pain (GERP). Empirical proton pump inhibitor (PPI) therapy has been recommended as an initial clinical approach for treating GERP. However, PPI use may lead to some health problems. The Gastroesophageal Reflux Disease Questionnaire (GerdQ) may represent a noninvasive and cost-effective approach for avoiding PPI misuse and for identifying the appropriate patients for the PPI trial test. The aim of this pilot study was to prospectively evaluate the association between GerdQ scores and PPI response in patients with coronary artery disease (CAD) and GERP to determine whether the GerdQ predicts the PPI response in patients with CAD and GERP and to further validate the clinical application value of the GerdQ. A total of 154 consecutive patients with potential GERP were recruited to complete a GerdQ with subsequent PPI therapy. Based on the PPI trial result, patients were divided into a PPI-positive response group and a PPI-negative response group. The difference in the GerdQ scores between the two groups was assessed. The receiver operating characteristic (ROC) curve of GerdQ score was drawn according to the PPI response as the gold standard. The ability of GerdQ to predict the PPI response was assessed. A total of 96 patients completed the entire study; 62 patients (64.6%) were assigned to the PPI-positive response group, and 34 patients (35.4%) to the PPI-negative response group. The GerdQ score of the PPI-positive response group (8.11 ± 3.315) was significantly higher than that of the PPI-negative response group (4.41 ± 2.743), and the difference was statistically significant (t = 5.863, P = 0.000). The ROC curve was drawn according to a PPI response assessment result with a score above 2 as the gold standard. The area under curve was 0.806. When the critical value of GerdQ score was 7.5, Youden index was up to 0.514, the diagnostic sensitivity

    The samples and data for this project are derived from 22 test holes drilled to a maximum depth of 91 m, and from rock exposures representing the carbonate section through the Miocene. Dolomite on St. Croix exists in a highly localized region of outcrops and subsurface occurrences in a Miocene-Pliocene reef tract and its related facies. Bioclasts in the dolomitic strata commonly show surprisingly good preservation of microstructure, particularly in large benthic forams and coralline algal clasts. The dolomite is stoichiometrically calcium-rich and exists as euhedral rhombs ranging from 2 to 30 ..mu..m in diameter. The surficial dolomitization occurs in reef, lagoonal, and platform facies that rim the predevelopment shoreline of a coastal lagoon. In the subsurface, dolomitized rock follows the lithifield undersurface of the same lagoon. This spatial distribution of dolomitization suggests a causal relationship between the lagoon hydrology and the process of the dolomitization. The preliminary Sr/sup 87//Sr/sup 86/ isotopic composition of the dolomite is 0.70888, which corresponds to Miocene-Pliocene seawater values, and suggests a Miocene-Pliocene age for the dolomitization event. Stable isotopic values average +2.3 o/oo for delta/sup 13/C and +4.1 o/oo for delta/sup 18/O, both relative to the PDB standard. These data imply that dolomitization took place by reflux of Pliocene fluids enriched in /sup 18/O. The dolomitization was confined to a fault-bounded region, and affected reef, lagoonal, and platform carbonates.

    Dextranomer/hyaluronic acid copolymer (Deflux) first received Food and Drug Administration approval in 2001 for endoscopic injection in children with grade II-IV vesicoureteral reflux VUR. As experience has grown, Deflux has been used more liberally with encouraging results. We report 3 cases where Deflux was used in off-label fashion, resulting in delayed ureteral obstruction and loss of renal function (range 18-52 months postoperatively). We now place increased emphasis on the need for long-term follow-up after Deflux in both routine and complex cases, particularly in situations of off-label use.

  19. From Reflux Esophagitis to Esophageal Adenocarcinoma.

    PubMed

    Souza, Rhonda F

    Reflux esophagitis causes Barrett's metaplasia, an abnormal esophageal mucosa predisposed to adenocarcinoma. Medical therapy for reflux esophagitis focuses on decreasing gastric acid production with proton pump inhibitors. We have reported that reflux esophagitis in a rat model develops from a cytokine-mediated inflammatory injury, not from a caustic chemical (acid) injury. In this model, refluxed acid and bile stimulate the release of inflammatory cytokines from esophageal squamous cells, recruiting lymphocytes first to the submucosa and later to the luminal surface. Emerging studies on acute reflux esophagitis in humans support this new concept, suggesting that reflux-induced cytokine release may be a future target for medical therapies. Sometimes, reflux esophagitis heals with Barrett's metaplasia, a process facilitated by reflux-related nitric oxide (NO) production and Sonic Hedgehog (Hh) secretion by squamous cells. We have shown that NO reduces expression of genes that promote a squamous cell phenotype, while Hh signaling induces genes that mediate the development of the columnar cell phenotypes of Barrett's metaplasia. Agents targeting esophageal NO production or Hh signaling conceivably could prevent the development of Barrett's esophagus. Persistent reflux promotes cancer in Barrett's metaplasia. We have reported that acid and bile salts induce DNA damage in Barrett's cells. Bile salts also cause NF-x03BA;B activation in Barrett's cells, enabling them to resist apoptosis in the setting of DNA damage and likely contributing to carcinogenesis. Oral treatment with ursodeoxycholic acid prevents the esophageal DNA damage and NF-x03BA;B activation induced by toxic bile acids. Altering bile acid composition might be another approach to cancer prevention.

    Introduction: Laryngopharyngeal reflux (LPR) is considered an important cause of voice disorder. We aimed to determine the frequency of LPR in patients with voice disorder and the association between Koufman Reflux Symptom Index (RSI), Reflux Finding Score (RFS), gastroesophageal reflux disease (GERD), and proximal acid reflux in these patients. Materials and Methods: We performed a prospective study in patients aged more than 18 years presenting at the ear, nose, and throat (ENT) clinic with a change in voice lasting more than 3 weeks. All patients underwent nasopharyngolaryngoscopy and a dual-probe esophageal pH study. LPR was diagnosed by a Koufman RSI of >13 and/or RFS of >7. GERD was diagnosed according to a DeMeester Johnson score of >14.7. Proximal acid reflux was diagnosed if acid exposure time was >0.02% in a proximal pH probe. Results: The study included 30 patients with a voice disorder. The mean age of participants was 38.5 years and 40% of patients were female. Using either of the two criteria, LPR was present in 46.7% of patients, half of whom had GERD. Among the remaining 53.3% patients with a voice disorder and no evidence of LPR, GERD was present in 25%. There was no significant association between the presence of LPR based on RSI (P=1) and GERD or RFS and GERD (P=0.06). Proximal acid reflux was present in only 10% patients with a voice disorder, and there was no significant association of this test with RFS (P=1) or RSI (P=1). Conclusions: Approximately half of the patients with a voice disorder have LPR, and only a subset of these patients have evidence of GERD. Fiberoptic laryngoscopic findings (RFS) complementing RSI appears to be important in diagnosing possible reflux etiology in voice disorders and can be an indicator for instituting anti-reflux therapy. However, there is no significant association between RSI, RFS, and GERD suggesting that these tests evaluate different features of the disease. Proximal acid reflux is uncommon in patients

    We propose a new method to help physicians assess, using a hepatobiliary iminodiacetic acid scan image, whether or not there is bile reflux into the stomach. The degree of bile reflux is an important index for clinical diagnosis of stomach diseases. The proposed method applies image-processing technology combined with a hydrodynamic model to determine the extent of bile reflux or whether the duodenum is also folded above the stomach. This condition in 2D dynamic images suggests that bile refluxes into the stomach, when endoscopy shows no bile reflux. In this study, we used optical flow to analyze images from Tc99m-diisopropyl iminodiacetic acid cholescintigraphy (Tc99m-DISIDA) to ascertain the direction and velocity of bile passing through the pylorus. In clinical diagnoses, single photon emission computed tomography (SPECT) is the main clinical tool for evaluating functional images of hepatobiliary metabolism. Computed tomography (CT) shows anatomical images of the external contours of the stomach, liver, and biliary extent. By exploiting the functional fusion of the two kinds of medical image, physicians can obtain a more accurate diagnosis. We accordingly reconstructed 3D images from SPECT and CT to help physicians choose which cross sections to fuse with software and to help them more accurately diagnose the extent and quantity of bile reflux.

    Bruxism is a pathological activity of the stomatognathic system that involves tooth grinding and clenching during parafunctional jaw movements. Clinical signs of bruxism are mostly related to dental wear and muscular and joint discomforts, but a large number of etiological factors can be listed, as local, systemic, psychological and hereditary factors. The association between bruxism, feeding and smoking habits and digestive disorders may lead to serious consequences to dental and related structures, involving dental alterations (wear, fractures and cracks), periodontal signs (gingival recession and tooth mobility) and muscle-joint sensivity, demanding a multidisciplinary treatment plan. This paper presents a case report in which bruxism associated with acid feeding, smoking habit and episodes of gastric reflow caused severe tooth wear and great muscular discomfort with daily headache episodes. From the diagnosis, a multidisciplinary treatment plan was established. The initial treatment approach consisted of medical follow up with counseling on diet and smoking habits and management of the gastric disorders. This was followed by the installation of an interocclusal acrylic device in centric relation of occlusion (CRO) for reestablishment of the occlusal stability, vertical dimension of occlusion, anterior guides and return to normal muscle activity (90-day use approximately). After remission of initial symptoms, oral rehabilitation was implemented in CRO by means of full resin composite restorations and new interocclusal device for protection of restorations. Satisfactory esthetics, improved function and occlusal stability were obtained after oral rehabilitation. The patient has attended annual follow-ups for the past 2 years. The multidisciplinary treatment seems to be the key for a successful rehabilitation of severe cases of dental wear involving the association of different health disorders. PMID:19089153

    A 68-question Internet survey was used to determine the impact of televised direct-to-consumer advertising (DTCA) on consumer-initiated medication changes for the treatment of gastroesophageal reflux disease (GERD) and social anxiety disorder (SAD). Of the 427 respondents, 10% that viewed DTCA for GERD and 6% that viewed DTCA for SAD reported that they subsequently initiated a conversation with their physician. Nearly half of respondents, 47.4% for GERD and 40% for SAD, reported that a change in therapy occurred as a direct result of these discussions. Televised DTCA for these two drug classes can have a significant impact on patient-initiated prescription requests.

    The mother of a 3-month old girl presented her daughter for chiropractic care with a medical diagnosis of gastroesophageal reflux disease. Her complaints included frequently interrupted sleep, excessive intestinal gas, frequent vomiting, excessive crying, difficulty breastfeeding, plagiocephaly and torticollis. Previous medical care consisted of Prilosec prescription medication. Notable improvement in the patient’s symptoms was observed within four visits and total resolution of symptoms within three months of care. This case study suggests that patients with complaints associated with both musculoskeletal and non-musculoskeletal origin may benefit from chiropractic care. PMID:19066699

    Background The RANGE (Retrospective ANalysis of GastroEsophageal reflux disease [GERD]) study assessed differences among patients consulting a primary care physician due to GERD-related reasons in terms of: symptoms, diagnosis and management, response to treatment, and effects on productivity, costs and health-related quality of life. This subanalysis of RANGE determined the impact of GERD on productivity in work and daily life. Methods RANGE was conducted at 134 primary care sites across six European countries (Germany, Greece, Norway, Spain, Sweden and the UK). All subjects (aged ≥18 years) who consulted with their primary care physician over a 4-month identification period were screened retrospectively, and those consulting at least once for GERD-related reasons were identified (index visit). From this population, a random sample was selected to enter the study and attended a follow-up appointment, during which the impact of GERD on productivity while working (absenteeism and presenteeism) and in daily life was evaluated using the self-reported Work Productivity and Activity Impairment Questionnaire for patients with GERD (WPAI-GERD). Results Overall, 373,610 subjects consulted with their primary care physician over the 4-month identification period, 12,815 for GERD-related reasons (3.4%); 2678 randomly selected patients attended the follow-up appointment. Average absenteeism due to GERD was highest in Germany (3.2 hours/week) and lowest in the UK (0.4 hours/week), with an average of up to 6.7 additional hours/week lost due to presenteeism in Norway. The average monetary impact of GERD-related work absenteeism and presenteeism were substantial in all countries (from €55/week per employed patient in the UK to €273/patient in Sweden). Reductions in productivity in daily life of up to 26% were observed across the European countries. Conclusion GERD places a significant burden on primary care patients, in terms of work absenteeism and presenteeism and in daily

    Acid-related diseases (ARDs), such as peptic ulcers and gastroesophageal reflux disease, represent a major health-care concern. Some major milestones in our understanding of gastric acid secretion and ARD treatment reached during the last 50years include 1) discovery of histamine H2-receptors and development of H2-receptor antagonists, 2) identification of H(+),K(+)-ATPase as the parietal cell proton pump and development of proton pump inhibitors (PPIs), and 3) identification of Helicobacter pylori (H. pylori) as the major cause of peptic ulcers and development of effective eradication regimens. Although PPI treatments have been effective and successful, there are limitations to their efficacy and usage, i.e. short half-life, insufficient acid suppression, slow onset of action, and large variation in efficacy among patients due to CYP2C19 metabolism. Potassium-competitive acid blockers (P-CABs) inhibit H(+),K(+)-ATPase in a reversible and K(+)-competitive manner, and exhibit almost complete inhibition of gastric acid secretion from the first dose. Many pharmaceutical companies have tried to develop P-CABs, but most of their clinical development has been discontinued due to safety concerns or a similar efficacy to PPIs. Revaprazan was developed in Korea and was the first P-CAB approved for sale. Vonoprazan, approved in 2014 in Japan, has a completely different chemical structure and higher pKa value compared to other P-CABs, and exhibits rapid onset of action and prolonged control of intragastric acidity. Vonoprazan is an effective treatment for ARDs that is especially effective in healing reflux esophagitis and for H. pylori eradication. P-CABs, such as vonoprazan, promise to further improve the management of ARDs.

    Introduction The indirect laryngoscopy has an important role in the characterization of reflux laryngitis. Although many findings are nonspecific, some strongly suggest that the inflammation is the cause of reflux. Objective The aim of this study was to evaluate the correlation between reflux symptoms and the findings of indirect laryngoscopy. Methods We evaluated 27 patients with symptoms of pharyngolaryngeal reflux disease. Results Laryngoscopy demonstrated in all patients the presence of hypertrophy of the posterior commissure and laryngeal edema. The most frequent symptoms were the presence of dry cough and foreign body sensation. Conclusion There was a correlation between the findings at laryngoscopy and symptoms of reflux. PMID:26157498

    Gastroesophageal reflux (GER) is a common gastrointestinal process that can generate symptoms of heartburn and chest pain. Proton pump inhibitors (PPIs) are the gold standard for the treatment of GER; however, a substantial group of GER patients fail to respond to PPIs. In the past, it was believed that acid reflux into the esophagus causes all, or at least the majority, of symptoms attributed to GER, with both erosive esophagitis and nonerosive outcomes. However, with modern testing techniques it has been shown that, in addition to acid reflux, the reflux of nonacid gastric and duodenal contents into the esophagus may also induce GER symptoms. It remains unknown how weakly acidic or alkaline refluxate with a pH similar to a normal diet induces GER symptoms. Esophageal hypersensitivity or functional dyspepsia with superimposed heartburn may be other mechanisms of symptom generation, often completely unrelated to GER. Detailed studies investigating the pathophysiology of esophageal hypersensitivity are not conclusive, and definitions of the various disease states may overlap and are often confusing. The authors aim to clarify the pathophysiology, definition, diagnostic techniques and medical treatment of patients with heartburn symptoms who fail PPI therapy.

    INTRODUCTION Fundoplication for laryngopharyngeal disease with oesophageal dysmotility has led to mixed outcomes. In the presence of preoperative dysphagia and oesophageal dysmotility, this procedure has engendered concern in certain regards. METHODS This paper describes a consecutive series of laryngopharyngeal reflux (LPR) patients with a high frequency of dysmotility. Patients were selected for surgery with 24-hour dual channel pH monitoring, oesophageal manometry and standardised reflux scintigraphy. RESULTS Following careful patient selection, 33 patients underwent fundoplication by laparoscopy. Surgery had high efficacy in symptom control and there was no adverse dysphagia. CONCLUSIONS Evidence of proximal reflux can select a group of patients for good results of fundoplication for atypical symptoms.

    Nonerosive reflux disease (NERD) is commonly diagnosed in patients with symptoms of reflux. The aim of the present study was to determine whether high-definition endoscopy (HD) plus equipped with the iScan function or chromoendoscopy with Lugol's solution might permit the differentiation of NERD patients from those without reflux symptoms, proven by targeted biopsies of endoscopic lesions. A total of 100 patients without regular intake of proton pump inhibitors and with a normal conventional upper endoscopy were prospectively divided into NERD patients and controls. A second upper endoscopy was performed using HD+ with additional iScan function and then Lugol's solution was applied. Biopsy specimens were taken from the gastroesophageal junction in all patients. A total of 65 patients with reflux symptoms and 27 controls were included. HD(+) endoscopy with iScan revealed subtle mucosal breaks in 52 patients; the subsequent biopsies confirmed esophagitis in all cases. After Lugol's solution, 58 patients showed mucosal breaks. Sensitivity for the iScan procedure was 82.5%, whereas that for Lugol's solution was 92.06%. Excellent positive predictive values of 100% and 98.3%, respectively, were noted. The present study suggests that the majority of patients with NERD and typical symptoms of reflux disease can be identified by iScan or Lugol's chromoendoscopy as minimal erosive reflux disease (ERD) patients.

    The endoscopic injection of Dx/HA in the management of vesicoureteral reflux (VUR) has become an accepted alternative to open surgery. In the current study we evaluated the value of cystography to detect de novo contralateral VUR in unilateral cases of VUR at the time of Dx/HA injection and correlated the findings of immediate post-Dx/HA injection cystography during the same anesthesia to 2-month postoperative VCUG to evaluate its ability to predict successful surgical outcomes. The current study aimed to evaluate whether an intraoperatively performed cystogram could replace postoperative studies. But a negative intraoperative cystogram correlates with the postoperative study in only 80%. Considering the 75-80% success rate of Dx/HA implantation, the addition of intraoperative cystograms cannot replace postoperative studies. In patients treated with unilateral VUR, PIC cystography can detect occult VUR and prevent postoperative contralateral new onset of VUR.

    2016-09-01

    Early in the twenty-first century, novel endoscopic techniques were introduced for the management of gastroesophageal reflux disease, providing minimally invasive ways to eliminate pharmacologic acid inhibition and avoid the need for anti-reflux surgery. These techniques do not significantly alter the anatomy of the gastroesophageal junction, minimizing short- and long-term adverse effects, such as dysphagia and bloating. After extensive clinical testing, many endoscopic therapies were abandoned due to either lack of durable efficacy or unfavorable safety profile. Today, only four such therapies remain clinically available, each with variable levels of clinical validation and market penetration. This review will provide an assessment of these endoscopic therapies, highlighting their respective strengths and weaknesses and their present and future applicability to patients with gastroesophageal reflux disease.

Two clinical cases of reflux nephropathy without evidence of reflux are presented. Several explanations could be advocated to justify this picture, including haematogenous source of infection, inadequate timing and/or procedure of cystouretrography, intermittency of reflux, ascending bacteria, previous presence of reflux, and appearance of controlateral reflux during the natural history of a monolateral documented reflux. Tailored diagnostic and therapeutic strategy should discussed for each patient.

    Background The correlation between treatment satisfaction and demographic characteristics, symptoms, or health-related quality of life (HRQL) in patients with gastroesophageal reflux disease (GERD) is unknown. The objective of this study was to assess correlates of treatment satisfaction in patients with GERD receiving a proton pump inhibitor, esomeprazole. Methods Adult GERD patients (n = 217) completed demography, symptom, HRQL, and treatment satisfaction questionnaires at baseline and/or after treatment with esomeprazole 40 mg once daily for 4 weeks. We used multiple linear regressions with treatment satisfaction as the dependent variable and demographic characteristics, baseline symptoms, baseline HRQL, and change scores in HRQL as independent variables. Results Among the demographic variables only Caucasian ethnicity was positively associated with treatment satisfaction. Greater vitality assessed by the Quality of Life in Reflux and Dyspepsia (QOLRAD) and worse heartburn assessed by a four-symptom scale at baseline, were associated with greater treatment satisfaction. The greater the improvement on the QOLRAD vitality (change score), the more likely the patient is to be satisfied with the treatment. Conclusions Ethnicity, baseline vitality, baseline heartburn severity, and change in QOLRAD vitality correlate with treatment satisfaction in patients with GERD. PMID:15649314

    A significant occurrence of vesicoureteric reflux in siblings of children with reflux has been previously suggested. The purpose of this study was to evaluate the incidence of vesicoureteric reflux in asymptomatic siblings of children with vesicoureteric reflux using radionuclide voiding cystography (RNC). A random group of 52 siblings was studied. Their ages were from 2 mos. to 13 yrs. (mean 4 yrs.). Seventy-one percent were female and 29% male, RNC was performed with the patients supine, and Tc-99m pertechnetate (2mCi/1) was infused into the bladder by catheter. A computerized gamma camera recorded the filling and voiding phase of the study at 1 frame/5 sec. Reflux was detected in 40% of the patients. It was bilateral in 17% and unilateral in 23% of the patients. Reflux was identified to the renal pelves in half of the patients. In two of these patients Tc-99m DMSA scans were obtained which revealed significant renal scarring. This study demonstrates the high incidence of reflux of various degrees in these asymptomatic siblings on high risk of developing significant renal disease. Identification and proper treatment of asymptomatic children with vesicoureteric reflux may help prevent the development of renal damage.

    Abnormal degrees of gastro-oesophageal reflux (GOR) were detected by 24 hour intraoesophageal pH measurement in 12 of 14 children (mean age 7.9 years; range 5 months-16 years) affected by cystic fibrosis and complaining of symptoms suggesting GOR. These patients underwent combined recording of distal oesophageal motility and intraluminal pH in order to investigate mechanisms of GOR. Inappropriate lower oesophageal sphincter relaxation was the most common mechanism of reflux in all patients. Other mechanisms (appropriate relaxation or lowered pressure of the lower oesophageal sphincter, increased intragastric pressure) were detected less frequently. Frequency of inappropriate lower oesophageal sphincter relaxations was significantly higher in patients with cystic fibrosis than in other study groups (symptomatic GOR, GOR disease complicated by respiratory complaints). Inappropriate lower oesophageal sphincter relaxations occurred with the same frequency in patients with cystic fibrosis and in a group of children with GOR disease complicated by oesophagitis. Abnormalities of distal oesophageal contractions such as decreased amplitude or uncoordinated waves were also recorded in cystic fibrosis patients. Seven patients with cystic fibrosis completed a therapeutic trial for eight weeks consisting of postural treatment and oral cisapride, a new prokinetic drug. The oesophageal acid exposure improved in only three patients. We conclude that pathologic GOR is commonly associated with cystic fibrosis. The predominant reflux mechanism in these patients is a transient inappropriate lower oesophageal sphincter relaxation rather than a low steady state basal lower oesophageal sphincter pressure.

    Gastroesophageal reflux disease (GORD) is more frequent among people with intellectual disability than among the intellectually normal population. Also GORD is more serious in this population. The diagnosis is often missed, because most intellectually disabled cannot express their complaints of GORD. For that reason a multidisciplinary working group of the Dutch Association of physicians active in the care of persons with a mental handicap has developed guidelines. The working group recommends endoscopy in case of a (alarm) symptoms: haematemesis, prolonged vomiting, irondeficiency anaemia e.c.i., and a 24 hour oesophageal pH test in case of b (aspecific) symptoms: recurrent pneumonia, refusal of food, regurgitation, rumination, dental erosions. In general most patients are cured with drug treatment (omeprazol or another proton pump inhibitor). If symptoms are not improved after 6 months of optimal treatment, surgical treatment may be considered.

    Gastro-oesophageal reflux and aspiration have been associated with chronic and end-stage lung disease and with allograft injury following lung transplantation. This raises the possibility that bile acids may cause lung injury by damaging airway epithelium. The aim of this study was to investigate the effect of bile acid challenge using the immortalised human bronchial epithelial cell line (BEAS-2B). The immortalised human bronchial epithelial cell line (BEAS-2B) was cultured. A 48-h challenge evaluated the effect of individual primary and secondary bile acids. Post-challenge concentrations of interleukin (IL)-8, IL-6 and granulocyte−macrophage colony-stimulating factor were measured using commercial ELISA kits. The viability of the BEAS-2B cells was measured using CellTiter-Blue and MTT assays. Lithocholic acid, deoxycholic acid, chenodeoxycholic acid and cholic acid were successfully used to stimulate cultured BEAS-2B cells at different concentrations. A concentration of lithocholic acid above 10 μmol·L−1 causes cell death, whereas deoxycholic acid, chenodeoxycholic acid and cholic acid above 30 μmol·L−1 was required for cell death. Challenge with bile acids at physiological levels also led to a significant increase in the release of IL-8 and IL6 from BEAS-2B. Aspiration of bile acids could potentially cause cell damage, cell death and inflammation in vivo. This is relevant to an integrated gastrointestinal and lung physiological paradigm of chronic lung disease, where reflux and aspiration are described in both chronic lung diseases and allograft injury.

    Background We designed this study to investigate the influence of different ratios of n-6/n-3 polyunsaturated fatty acid in the diet of reflux esophagitis (RE) rats’ and the effect on the PI3K/Akt pathway. Material/Methods RE rats were randomly divided into a sham group and modeling groups of different concentrations of n-6/n-3 polyunsaturated fatty acid (PUFA): 12:1 group, 10:1 group, 5:1 group, and 1:1 group. RT-PCR and Western-blot were used to detect the expression of PI3K, Akt, p-Akt, NF-κBp50, and NF-κBp65 proteins in esophageal tissue. Results In the n-6/n-3 PUFAs groups the expression of PI3K, Akt, p-Akt, nf-kbp50, and NF-κBp65 mRNA decreased with the decrease in n-6/n-3 ratios in the diet. The lowest expression of each indicator occurred in the 1:1 n-6/n-3 group compared with other n-6/n-3 groups, the difference was statistically significant (p<0.05). Conclusions The inhibition of n-3 PUFAs in the development of esophageal inflammation in rats with RE was attributed to the function of PI3K/Akt-NF-κB signaling pathway. PMID:28134235

    Objective To estimate excess health care expenditures associated with gastroesophageal reflux disease (GERD) among elderly individuals with chronic obstructive pulmonary disease (COPD) and examine the contribution of predisposing characteristics, enabling resources, need variables, personal health care practices, and external environment factors to the excess expenditures, using the Blinder–Oaxaca linear decomposition technique. Methods This study utilized a cross-sectional, retrospective study design, using data from multiple years (2006–2009) of the Medicare Current Beneficiary Survey linked with fee-for-service Medicare claims. Presence of COPD and GERD was identified using diagnoses codes. Health care expenditures consisted of inpatient, outpatient, prescription drugs, dental, medical provider, and other services. For the analysis, t-tests were used to examine unadjusted subgroup differences in average health care expenditures by the presence of GERD. Ordinary least squares regressions on log-transformed health care expenditures were conducted to estimate the excess health care expenditures associated with GERD. The Blinder–Oaxaca linear decomposition technique was used to determine the contribution of predisposing characteristics, enabling resources, need variables, personal health care practices, and external environment factors, to excess health care expenditures associated with GERD. Results Among elderly Medicare beneficiaries with COPD, 29.3% had co-occurring GERD. Elderly Medicare beneficiaries with COPD/GERD had 1.5 times higher ($36,793 vs $24,722 [P<0.001]) expenditures than did those with COPD/no GERD. Ordinary least squares regression revealed that individuals with COPD/GERD had 36.3% (P<0.001) higher expenditures than did those with COPD/no GERD. Overall, 30.9% to 43.6% of the differences in average health care expenditures were explained by differences in predisposing characteristics, enabling resources, need variables, personal health care

    This study was designed to assess evidence for an association between the treatment of gastroesophageal reflux disease (GERD) with proton pump inhibitors (PPIs) and improvement in obstructive sleep apnea (OSA). We conducted a systematic review and meta-analysis of randomized controlled trials and prospective cohort studies to evaluate the treatment effect of PPIs on OSA symptoms and indices in patients with GERD. EMBASE, MEDLINE, the Cochrane Central Register of Controlled Trials, the Cochrane Database of Systematic Reviews, and ClinicalTrials.gov were reviewed up to October 2014. From 238 articles, two randomized trials and four prospective cohort studies were selected. In four cohort studies there were no differences in the apnea-hypopnea indices before and after treatment with PPIs (standard mean difference, 0.21; 95% confidence interval, −0.11 to 0.54). There was moderate heterogeneity among these studies. Two cohort studies revealed significantly decreased apnea indices after treatment (percent change, 31% and 35%), but one showed no significant difference. A significant improvement in the Epworth Sleepiness Scale was observed in three cohort studies and one trial. The frequency of apnea attacks recorded in diaries was decreased by 73% in one trial. In conclusion, available studies do not provide enough evidence to make firm conclusions about the effects of PPI treatment on OSA symptoms and indices in patients with concomitant GERD. Controlled clinical trials with larger sample sizes are needed to evaluate these associations. We recommend PPIs in OSA patients with concomitant GERD to treat reflux symptoms. This treatment may improve the quality of sleep without any effect on apnea-hypopnea indices. PMID:26722154

    Multilayered epithelium is defined as hybrid epithelium with characteristics of both squamous and columnar epithelia. Our aim was to evaluate the clinicopathological significance of the lesion by relating its presence to various histological and clinical and/or endoscopic features indicating gastroesophageal reflux disease (GERD). A total of 1,071 individuals participated in a prospective cross-sectional study (576 females and 495 males; median age 53 years). Biopsy material was systematically sampled from the gastroesophageal junction. The histological diagnosis of esophagitis was made according to the Esohisto consensus guidelines. The endoscopic diagnosis of esophagitis was made according to the modified Los Angeles classification and the diagnosis of Barrett's esophagus according to Prague's C & M criteria, respectively. Multilayered epithelium was identified in 103 (9.6 %) individuals, frequently within or adjacent to the ducts of esophageal glands. Its presence was associated with increasing age (p < 0.001), high BMI (p = 0.026), hiatal hernia (p < 0.001), and the endoscopic diagnoses of esophagitis (p = 0.002) and Barrett's esophagus (p < 0.001). Upon histology, multilayered epithelium was associated with features of the squamous epithelium indicating GERD, particularly intercellular space dilation (p = 0.005), and presence of cardiac mucosa (<0.001). For intestinal metaplasia, a trend was noted (p = 0.094). In conclusion, multilayered epithelium was observed in about every tenth individual undergoing upper gastrointestinal endoscopy. The association with histological and clinical features indicating GERD advocates the lesion as a promising new marker for reflux esophagitis. The association with cardiac mucosa and Barrett's esophagus suggests multilayered epithelium to be an intermediate step in the development of columnar metaplasia and, ultimately, Barrett's esophagus.

    This paper is a retrospective morphologic study of 7 young Boxer dogs, showing end-stage kidney lesions compatible with chronic pyelonephritis with severe segmental cortical atrophy and fibrosis, associated with chronic tubulointerstitial inflammation of varying degree. Azotemia was observed in 6 of the 7 cases. The gross kidney lesions were as follows: bilateral small kidneys with numerous segmental cortical scars causing depression of the renal cortical surface. Histologic examination revealed salient atrophy of nephrons, including paucity of glomeruli, glomerulocystic lesions, colloid-filled tubular microcysts, and a conspicuously increased occurrence of arteries with narrowed lumina caused by intimal thickening. These segmental abnormalities were accompanied by pronounced interstitial fibrosis. All but 1 dog showed salient tubulointerstitial lympho-plasmacytic infiltration, which in 3 cases also included diffuse infiltration of polymorphonuclear neutrophilic leukocyte (PMN)-cells and occurrence of tubular PMN-casts. Morphologic signs of abnormal metanephric differentiation (renal dysplasia) were observed in all cases in the form of atypical tubules or asynchronous nephronic development (immature glomeruli) or both. However, other morphologic primary dysplastic features were absent. Based on the morphologic features, it is concluded that the end-stage kidney disease in these young Boxer dogs was the result of chronic atrophic nonobstructive pyelonephritis, most probably caused by vesico-ureteral reflux, compatible with reflux nephropathy causing segmental hypoplasia (Ask-Upmark kidney) in man. It is proposed that atypical tubular epithelium in the form of adenomatoid proliferation of collecting duct epithelial cells should be considered an acquired compensatory lesion, rather than the result of disorganized metanephric development.

    Gastroesophageal reflux disease (GERD) is a common problem in neonatology. Various physiological protective reflex responses provide a plausible biological link between gastro-esophageal reflux and apnea and bradycardia in premature. It is uncertain whether or not there is a causal relationship between the two diseases. However there is no consensus about the clinical and paraclinical diagnosis. Further explorations and treatment offered to premature infants with symptoms are discussed. We report the case of a preterm infants admitted to neonatal intensive care and with apnea and bradycardia. Clinical examination and exploration results were normal. We retained the gastrointestinal reflux diagnosis complicated of apnea and bradycardia. Pharmacological therapy for gastro-esophageal reflux disease has not definitively been shown to be effective in improving symptoms and should be reserved especially for infants with treatment refractory apnea and bradycardia episodes suspected as being gastro-esophageal reflux in premature infants. From a case report we made a literature review to discuss at length the different aspects of the problem.

    Background Approximately, 20–30% of patients with gastro-esophageal reflux disease (GERD) experience persistent symptoms despite treatment with proton pump inhibitors (PPIs). These patients may have underlying dysmotility; therefore, targeting gastric motor dysfunction in addition to acid inhibition may represent a new therapeutic avenue. The aim of this study was to assess the pharmacodynamic effect of the prokinetic agent revexepride (a 5-HT4 receptor agonist) in patients with GERD who have persistent symptoms despite treatment with a PPI. Methods This was a phase II, exploratory, multicenter, randomized, placebo-controlled, double-blind, parallel-group study in patients with GERD who experienced persistent symptoms while taking a stable dose of PPIs (http://ClinicalTrials.gov identifier: NCT01370863). Patients were randomized to either revexepride (0.5 mg, three times daily) or matching placebo for 4 weeks. Reflux events and associated characteristics were assessed by pH/impedance monitoring and disease symptoms were assessed using electronic diaries and questionnaires. Key Results In total, 67 patients were enrolled in the study. There were no significant differences between study arms in the number, the mean proximal extent or the bolus clearance times of liquid-containing reflux events. Changes from baseline in the number of heartburn, regurgitation, and other symptom events were minimal for each treatment group and no clear trends were observed. Conclusions & Inferences No clear differences were seen in reflux parameters between the placebo and revexepride groups. PMID:25530111

    This paper aims at evaluating the impact of vitamins intake in the prevention of gastroesophageal reflux disease (GERD), Barrett's oesophagus (BE), and oesophageal adenocarcinoma (EADC). It concentrates primarily on the antioxidant vitamins A, C and E. There were 180 subjects included in the trial, 109 males and 71 females, which were divided in the four groups (70 patients with GERD, 20 patients with BE, 20 patients with EADC, and 70 healthy examinees composing a control group). Their antioxidant vitamins intake was investigated through the usage of the dietary questionnaires. Concentration of the mentioned antioxidant vitamin in serum was detected by HPLC method, and although there were no major statistical differences in their levels between four groups, there existed a correlation between the vitamin serum concentration and the rephlux disease degree. The results showed that the healthy examinees had consumed the greater quantities of the vitamins A, C and E, through both the natural (fruits and vegetables) and the supplementary (industrial vitamin additives) way, than the patients with GERD, BE and EADC. This was reflected in the higher serum levels of the mentioned vitamins in the first group in the comparison with the second group. Based on this, the intake of the vitamins A, C and E through both the natural and the supplementary ways is suggested in order to prevent the development of the GERD, BE and EADC.

    Refractory chronic cough due to gastroesophageal reflux is a troublesome condition unresponsive to the standard medical anti-reflux therapy. Its underlying mechanisms may include incomplete acid suppression, non-acid reflux, transient lower esophageal sphincter relaxations and esophageal hypersensitivity. The diagnosis of this disorder depends on both the findings of multi-channel intraluminal impedance-pH monitoring and the subsequent intensified anti-reflux therapy. The strategies of pharmacological treatment for refractory chronic cough due to reflux include the optimization of proton pump inhibitors and add-on therapies with histamine H2 receptor antagonists, baclofen and gabapentin. However, the further study is needed to satisfy its management.

    102 patients with GERD were examined: 70 female (68%) and 32 men (32%). Age of respondents ranged from 20 to 65 years (average of 45.8 ±8,2). All patients were randomly divided into 2 groups. In the first (control) group (30 people) traditional drug treatment were used according to the standard therapy of GERD (proton pump inhibitors, antacids, prokinetics), patients in the second (main) group (70 people) along with drug therapy has received a course of intravenous laser therapy according to the methods ILIB-405. For intravenous laser treatment Russian apparatus "Matrix-ILIB" ("Matrix", Russia) was used with wavelength 0,405 μm, output power at the end of the main optical path of 1-1.5 mW. Laser blood irradiation was carried out for 15 minutes in the CW mode, the course of treatment was 10 daily treatments with a break on Saturday and Sunday. Conclusions: 1. Intravenous laser irradiation of blood in the complex therapy of patients with gastroesophageal reflux disease improved significantly of HRV due to the alignment of parasympathetic regulation circuit and reducing the activity of sympathetic autonomic regulation, 2. the inclusion of intravenous laser irradiation of blood in the complex therapy of patients with GERD was accompanied by reliable normalization of the indicators of the daily pH-metry of the esophagus in patients with GERD.

    The association between gastroesophageal reflux disease (GERD) and asthma, although well established in adults, is less strong in the pediatric age group. Benefits of proton pump therapy are limited across age ranges. While there is a growing body of literature on the use of complementary treatments for both asthma and GERD, few studies have focused on treatment benefits for the GERD-asthma association. We present the case of a 2-year-old boy with asthma and GERD who was not responding to inhaled, low-dose corticosteroids, beta-mimetic therapy, and a 6-week course of proton pump inhibitor treatment. We noted a gradual disappearance of symptoms when he was given an oral preparation of Pulvis stomachicus cum Belladonna, an anthroposophic medication containing Matricaria recutita, Atropa belladonna, bismuth, and antimonite. Matricaria recutita and bismuth have known gastric protective properties, and Atropa belladonna contains anticholinergic agents that have a bronchodilatory effect. These complementary medications appear promising in terms of relieving the symptoms of GERD-associated asthma. PMID:26937321

    2013-01-01

    Background Gastrointestinal reflux disease (GERD) is a common disorder that negatively impacts health-related quality of life (HRQL) and work productivity. Many patients have only a partial response to proton pump inhibitor (PPI) therapy and continue to experience GERD symptoms despite optimized treatment. This observational study aimed to provide information on symptoms, HRQL, resource usage, costs and treatment pathways associated with partial response to PPI therapy in French patients with GERD. Methods Patients with partial response to PPI therapy, defined as persistent GERD symptoms ≥3 days/week despite optimized treatment with a PPI, were recruited for this 12-month observational study. GERD symptoms, HRQL, work productivity and resource use were assessed by patient surveys. Costs were calculated based on lost work productivity and resource use. Results The patient population (n=262; mean age, 54 years; 40% men) carried a significant symptom burden, with 98% of patients having moderate-to-severe GERD symptoms and 65% of patients experiencing daily symptoms at baseline. HRQL and work productivity were significantly impaired, with a greater degree of impairment in patients with higher symptom burden. The mean total cost per patient over the 12-month follow-up period was €5237, of which €4674 (89%) was due to lost work productivity. Conclusions Partial response to PPI therapy for GERD is associated with a high symptom burden, significant impairment of HRQL and work productivity, and substantial GERD-related costs. PMID:23448382

    Proton-pump inhibitors (PPIs) have been proved as safe and effective ways to treat patients with non-erosive reflux disease (NERD). However, less is known about the comparisons among different PPIs and their best dosage. We aimed to synthesize the available evidence through network meta-analysis to investigate the efficacy and safety of different PPIs in treating patients with NERD. Fifteen studies with 6309 patients were included in the meta-analyses. For the rate of symptomatic relief, compared with control groups, all interventions except rabeprazole 5 mg significantly increased rate of symptomatic relief. Among the comparisons of different interventions, omeprazole 20 mg group was associated with a higher rate of symptomatic relief in contrast to omeprazole 10 mg group (odds ratio, OR: 1.89, 95% confidence interval, CI: 1.34, 2.67; p-value: 0.0005) or rabeprazole 5 mg group (OR: 2.51, 95%CI: 1.16, 5.42; p-value: 0.019); dexlansoprazole 30 mg therapy significantly improved the rate of symptomatic relief compared with rabeprazole 5 mg group (OR: 2.64, 95%CI: 1.08, 6.43; p-value: 0.03). For the rate of adverse events, there was no significant difference among all interventions.

It was observed that GR–TiO{sub 2} showed higher adsorption compared to bare TiO{sub 2} (PTA). • The GR–TiO{sub 2} (PTA, 1:50) catalyst showed higher photocatalytic activity than any other catalyst. - Abstract: In the present work, graphene–TiO{sub 2} (GR–TiO{sub 2}) photocatalyst with various weight ratios of graphene was synthesized using peroxo titanic acid solution (PTA) as a precursor for TiO{sub 2}. Graphene oxide prepared by Hummer's method was converted to graphene under ultraviolet (UV) irradiation in ethanol–water solvent for 48 h. The as-prepared GR–TiO{sub 2} composites were characterized using X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, UV–vis spectrophotometry, and transmission electron microscopy (TEM). The automated potentiostat was applied to measure the photocurrent generations of prepared catalysts. The photocatalytic activities of GR–TiO{sub 2} (PTA) catalysts were determined by measuring the percentage methylene blue (MB) degradation. The results showed that TiO{sub 2} nanoparticles were successfully loaded onto graphene sheet and the surface area of catalysts increased with increasing weight ratio of graphene. In addition, GR–TiO{sub 2} (PTA, 1:50) exhibited the highest photocatalytic activity among the catalysts under UV and visible light irradiation. The adsorption edge of GR–TiO{sub 2} was shifted to a longer wavelength of 400 nm in comparison with that of pure TiO{sub 2} (PTA). The increase in the photocatalytic performance of GR–TiO{sub 2} (PTA) catalyst may be attributed to the increase in surface area, the extension of light absorption in

The purposes of this study were to investigate the presence of gastroesophageal reflux and establish the probable association between gastroesophageal reflux and pulmonary and gastric involvement. All 10 patients underwent 24-hour esophageal pH recording, spirometry and gastric function. Abnormal reflux index was found in all these patients. Lung function was pathologic in the 3 older children. There were no relationship between the severity of the gastroesophageal reflux and the degree of pulmonary damage. No patient has gastric acid hypersecretion. Eight of 10 patients had steatorrhea. Our findings confirm the high frequence of gastroesophageal reflux in cystic fibrosis.

    Recurrent gastroesophageal reflux following fundoplication is a challenging problem, because it is usually refractory to medical treatment and a second, technically difficult, antireflux operation is required. Different factors that may contribute to surgery failure have been identified in children. We present 8 cases who underwent redofundoplication after failed procedures, from a total number of 96 patients operated on due to gastroesophageal reflux. Four patient's had their initial fundoplication performed at our institution. Six patients were neurologically impaired, six had chronic pulmonary disease, and two had esophageal atresia. The main presenting symptoms were recurrent vomiting (n = 8) and aspiration (n = 4). Gastroesophageal reflux was confirmed by barium swallow and endoscopy. Operative findings showed wrap breakdown in two cases, warp breakdown associated with hiatal hernia in five, wrap breakdown associated with paraesophageal hernia in two cases, and paraesophageal hernia with normal wrap in one. A second Nissen procedure were performed in five cases, whereas a Collis-Nissen gastroplasty was realized in three with a short esophagus. Six patients had a successful outcome remaining symptom free, one has severe disphagia, and one has recurrent vomiting. In our experience, patients with recurrent gastroesophageal reflux disease should undergo an antireflux procedure tailored to specific anatomic or functional abnormalities.

    The mechanical force relationships that distinguish normal from chronic reflux at sphincter opening are poorly understood and difficult to measure in vivo. Our aim was to apply physics-based computer simulations to determine mechanical pathogenesis of gastroesophageal reflux. A mathematical model of the gastroesophageal segment (GES) was developed, incorporating the primary anatomical and physiomechanical elements that drive GES opening and reflux. In vivo data were used to quantify muscle stiffness, sphincter tone, and gastric pressure. The liquid lining the mucosa was modeled as an "effective liquid film" between the mucosa and a manometric catheter. Newton's second law was solved mathematically, and the space-time details of opening and reflux were predicted for systematic variations in gastric pressure increase, film thickness, muscle stiffness, and tone. "Reflux" was defined as "2 ml of refluxate entering the esophagus within 1 s." GES opening and reflux were different events. Both were sensitive to changes in gastric pressure and sphincter tone. Reflux initiation was extremely sensitive to the liquid film thickness; the protective function of the sphincter was destroyed with only 0.4 mm of liquid in the GES. Compliance had no effect on reflux initiation, but affected reflux volume. The presence of abnormal levels of liquid within the collapsed GES can greatly increase the probability for reflux, suggesting a mechanical mechanism that may differentiate normal reflux from gastroesophageal reflux disease. Compliance does not affect the probability for reflux, but affects reflux volume once it occurs. Opening without reflux suggests the existence of "gastroesophageal pooling" in the distal esophagus, with clinical implications.

    Gastro-esophageal reflux disease (GERD) is one of the most common disorders in gastroenterology. Patients present with or without increased acid exposure indicating a nonuniform etiology. Thus, the common treatment with proton pump inhibitors (PPIs) fails to control symptoms in up to 40% of patients. To further elucidate the pathophysiology of the condition and explore new treatment targets, transcriptomics, proteomics and histological methods were applied to a surgically induced subchronic reflux esophagitis model in Wistar rats after treatment with either omeprazole (PPI) or STW5, a herbal preparation shown to ameliorate esophagitis without affecting refluxate pH. The normal human esophageal squamous cell line HET-1A and human endoscopic biopsies were used to confirm our findings to the G-protein–coupled receptor (GPR) 84 in human tissue. Both treatments reduced reflux-induced macroscopic and microscopic lesions of the esophagi as well as known proinflammatory cytokines. Proteomic and transcriptomic analyses identified CINC1–3, MIP-1/3α, MIG, RANTES and interleukin (IL)-1β as prominent mediators in GERD. Most regulated cyto-/chemokines are linked to the TREM-1 signaling pathway. The fatty acid receptor GPR84 was upregulated in esophagitis but significantly decreased in treated groups, a finding supported by Western blot and immunohistochemistry in both rat tissue and HET-1A cells. GPR84 was also found to be significantly upregulated in patients with grade B reflux esophagitis. The expression of GPR84 in esophageal tissue and its potential involvement in GERD are reported for the first time. IL-8 (CINC1–3) and the TREM-1 signaling pathway are proposed, besides GPR84, to play an important role in the pathogenesis of GERD.org PMID:26650186

    Venous incompetence in the lower extremity is a common clinical problem. Basic understanding of venous anatomy, pathophysiologic mechanisms of venous reflux is essential for choosing the appropriate treatment strategy. The complex interplay of venous pressure, abdominal pressure, venous valvular function and gravitational force determine the venous incompetence. This review is intended to provide a succinct review of the pathophysiology of venous incompetence and the current role of imaging in its management. PMID:28123974

    In spite of poor evidence, many patients with gastro-oesophageal reflux are advised to avoid fat and spices. We therefore measured gastro-oesophageal reflux after fatty and spicy meals. During three 24-h pH monitoring sessions, eight volunteers ate two identical, low fat and mild beef stews, or a hot and fatty Indian curry for lunch. Meals for dinner were the beef stew, the hot Indian curry or a mild curry. Day-time acid exposure was significantly longer after the hot curry (7.5 % [1.4 - 27.1]) than after the beef stews (2.3 % [0.4 - 9.8] and 2.5 % [0.7 - 15.7]). Night-time acid exposure was also significantly shorter after the beef stew (1.3 % [0 - 9]) than after the mild curry (2.9 % [0 - 19.1]) or the hot curry (4.6 % [0.2 - 22.5]). Within two hours postprandially, reflux was not different between the meals. The number of episodes, however, that occurred more than two hours after lunch was significantly lower after the beef stews (4 [2 - 14] and 4.5 [2 - 10]) than after the hot curry (9 [5 - 16]). The same phenomenon was observed after beef stew (0.5 [0 - 2]), mild curry (2 [0 - 4]) and hot curry (2 [1 - 9]) for dinner. We conclude that meals high in fat can provoke reflux, possibly through delayed gastric emptying. Additional spices, however, do not further increase reflux.

    Study Objectives : Nocturnal bruxism is associated with gastroesophageal reflux disease (GERD), and GERD is strongly associated with obstructive sleep apnea (OSA). Gender and ethnic differences in the prevalence and clinical presentation of these often overlapping sleep disorders have not been well documented. Our aim was to examine the associations between, and the symptoms associated with, nocturnal GERD and sleep bruxism in patients with OSA, and to examine the influence of gender and ethnicity. Methods : A retrospective chart review was performed of patients diagnosed with OSA at an academic sleep center. The patients completed a sleep questionnaire prior to undergoing polysomnography. Patients with confirmed OSA were evaluated based on gender and ethnicity. Associations were determined between sleep bruxism and nocturnal GERD, and daytime sleepiness, insomnia, restless legs symptoms, and markers of OSA severity in each group. Results : In these patients with OSA, the prevalence of nocturnal GERD (35%) and sleep bruxism (26%) were higher than the general population. Sleep bruxism was more common in Caucasians than in African Americans or Hispanics; there was no gender difference. Nocturnal GERD was similar among all gender and ethnic groups. Bruxism was associated with nocturnal GERD in females, restless legs symptoms in all subjects and in males, sleepiness in African Americans, and insomnia in Hispanics. Nocturnal GERD was associated with sleepiness in males and African Americans, insomnia in females, and restless legs symptoms in females and in Caucasians. Conclusion : Patients with OSA commonly have comorbid sleep bruxism and nocturnal GERD, which may require separate treatment. Providers should be aware of differences in clinical presentation among different ethnic and gender groups. PMID:25352924

    Context The incidences of both gastroesophageal reflux disease (GERD) and metabolic syndrome (MetS) have increased in recent years, and it has been suggested that there is a probable association between the two. The aim of this review is to clarify whether or not MetS is a risk factor for the incidence of GERD. Evidence Aquisition We searched the PubMed, ProQuest, Ovid, Science Direct, and Google Scholar databases up to February 2015 regarding the relationship between GERD and MetS as found in observational studies. Any studies that evaluated the association between the components of MetS and GERD, as well as any studies examining the association of MetS with Barrett’s esophagus or esophageal carcinoma, were excluded. Results Thirteen studies met the eligibility criteria. The results of nine studies suggested that there was a higher prevalence of MetS among patients with GERD (P < 0.05) and, thus, it could be considered as an independent risk factor for the incidence of GERD. However, in the one study was not observed significant association between GERD and MetS (P = 0.71). Two studies in which the prevalence of GERD was compared between individuals with and without MetS showed a higher prevalence of GERD in patients with MetS (P < 0.05). However, this finding was not observed in a similar study conducted among female participants, which reported that the different types of MetS were not important factors with regard to the prevalence of erosive esophagitis (P = Not significant). Conclusions It can be concluded that MetS may increase the risk of GERD. Consequently, there might be potential benefits to treating the metabolic abnormalities in these patients. PMID:28191340

    The mechanical force relationships that distinguish normal from chronic reflux at sphincter opening are poorly understood and difficult to measure in vivo. Our aim was to apply physics-based computer simulations to determine mechanical pathogenesis of gastroesophageal reflux. A mathematical model of the gastroesophageal segment (GES) was developed, incorporating the primary anatomical and physiomechanical elements that drive GES opening and reflux. In vivo data were used to quantify muscle stiffness, sphincter tone, and gastric pressure. The liquid lining the mucosa was modeled as an “effective liquid film” between the mucosa and a manometric catheter. Newton's second law was solved mathematically, and the space-time details of opening and reflux were predicted for systematic variations in gastric pressure increase, film thickness, muscle stiffness, and tone. “Reflux” was defined as “2 ml of refluxate entering the esophagus within 1 s.” GES opening and reflux were different events. Both were sensitive to changes in gastric pressure and sphincter tone. Reflux initiation was extremely sensitive to the liquid film thickness; the protective function of the sphincter was destroyed with only 0.4 mm of liquid in the GES. Compliance had no effect on reflux initiation, but affected reflux volume. The presence of abnormal levels of liquid within the collapsed GES can greatly increase the probability for reflux, suggesting a mechanical mechanism that may differentiate normal reflux from gastroesophageal reflux disease. Compliance does not affect the probability for reflux, but affects reflux volume once it occurs. Opening without reflux suggests the existence of “gastroesophageal pooling” in the distal esophagus, with clinical implications. PMID:18718998

    Vesicoureteral reflux (VUR) may be congenital or acquired. The most frequent form of congenital VUR is primary VUR. Its prevalence in adults is not exactly known, but it is higher in women, whose greater propensity for urinary tract infections increases the likelihood of an instrumental examination leading to the diagnosis of less severe cases. In men, even severe VUR may go undiagnosed for a long time. Primary VUR is due to a defect in the valve mechanism of the ureterovesical junction. In physiological conditions, the terminal ureter enters the bladder wall obliquely and bladder contraction leads to compression of this intravesical portion. Abnormal length of the intravesical portion of the ureter due to a genetic mutation (whose location is yet to be established) leads to VUR. In its less severe forms VUR may be asymptomatic, but in 50-70% of cases it manifests with recurrent cystitis or pyelonephritis. The manifestations leading to a diagnosis of VUR in adults, besides urinary tract infections, are proteinuria, renal failure and hypertension. The gold-standard diagnostic examination is a micturating cystourethrogram. Reflux nephropathy develops as a result of a pathogenetic mechanism unrelated to high cavity pressure or urinary tract infections but due to reduced formation of the normal renal parenchyma (hypoplasia or dysplasia). Abnormal renal parenchyma development is attributable to the same genes that control the development of the ureters and ureterovesical junction. VUR is considered only a marker of this abnormal development, playing no role in scar formation. There is no conclusive evidence regarding the indications for VUR correction. However, the risk that VUR leads to recurrent pyelonephritis and reflux nephropathy must be kept in mind. VUR certainly has to be corrected in women who contemplate pregnancy.

    A nebulization reflux concentrator for removing trace gas contaminants from a sample gas is described. Sample gas from a gas supply is drawn by a suction source into a vessel. The gas enters the vessel through an atomizing nozzle, thereby atomizing and entraining a scrubbing liquid solvent drawn through a siphon tube from a scrubbing liquid reservoir. The gas and entrained liquid rise through a concentrator and impinge upon a solvent phobic filter, whereby purified gas exits through the filter housing and contaminated liquid coalesces on the solvent phobic filter and falls into the reservoir.

    Nebulization reflux concentrator extracts and concentrates trace quantities of water-soluble gases for subsequent chemical analysis. Hydrophobic membrane and nebulizing nozzles form scrubber for removing trace quantities of soluble gases or other contaminants from atmosphere. Although hydrophobic membrane virtually blocks all transport of droplets, it offers little resistance to gas flow; hence, device permits relatively large volumes of gas scrubbed efficiently with very small volumes of liquid. This means analyzable quantities of contaminants concentrate in extracting solutions in much shorter times than with conventional techniques.

  19. Novel therapeutics for gastro-esophageal reflux symptoms.

    Zerbib, Frank; Simon, Mireille

    2012-09-01

    Approximately 20-30% of patients with gastro-esophageal reflux symptoms report inadequate symptom relief while on proton-pump inhibitor therapy. The mechanisms involved are failure of the antireflux barrier (transient lower esophageal sphincter relaxations), high proximal extent of the refluxate, esophageal hypersensitivity and impaired mucosal integrity. Persisting acid or nonacid reflux can be demonstrated in 40-50% of cases, suggesting that there is room for antireflux therapy in these patients. New antireflux compounds have been shown to decrease the occurrence of transient lower esophageal sphincter relaxations. The most promising classes of compounds are GABA type B agonists and metabotropic glutamate receptor 5 antagonists, which can reduce both reflux episodes and symptoms, but the development of these compounds has been abandoned for either safety issues or lack of efficacy. Esophageal hypersensitivity and impaired mucosal integrity may prove to be relevant therapeutic targets in the future.

    Epidemiologic cohort studies have established that after distal gastric resection, there is a higher risk of gastric carcinoma. It is likely that a main factor of this higher risk is the excessive duodenogastric reflux induced by surgery, because the incidence of stump carcinomas is higher in Billroth II than in Billroth I, and most of the stump carcinomas are located near the stoma. In addition, several groups of investigators have suggested that duodenogastric reflux per se induces stump carcinomas in rats. There is another human duodenogastric reflux, the primary duodenogastric reflux, through the pylorus. Experiments in animals have demonstrated that this type of duodenal reflux also induces gastric carcinomas in the antrum of the stomach that has not undergone surgery. Recent clinical attention has focused on the role of duodenogastric reflux in the pathogenesis of Barrett's esophagus and subsequent esophageal adenocarcinomas. Experimentally, reflux of duodenal contents into the esophagus can cause not only Barrett's esophagus and subsequent adenocarcinomas, but also squamous cell carcinomas. These findings suggest that duodenogastric reflux may be implicated in gastric and esophageal, that is, foregut carcinogenesis.

    Purpose The cation exchanger, a potentiated clinoptilolite (Absorbatox™ 2.4D), is a synthetically enhanced aluminosilicate. The aim of this study was to evaluate the possible benefits of a potentiated clinoptilolite as a gastroprotective agent in reducing the severity of clinical symptoms and signs associated with 1) endoscopically negative gastroesophageal reflux disease (ENGORD) and 2) nonsteroidal anti-inflammatory drug (NSAID) medication. Methods and patients Two randomized, double-blind, placebo-controlled, pilot studies, the ENGORD and NSAID studies, were conducted. After initial negative gastroscopy, a total of 25 patients suffering from ENGORD were randomized to receive either placebo capsules or 750 mg Absorbatox twice daily for 14 days. The NSAID study recruited 23 healthy patients who received orally either 1,500 mg Absorbatox or placebo three times daily, plus 500 mg naproxen twice daily. Patients underwent gastroscopic evaluation of their stomach linings prior to and on day 14 of the study. Gastric biopsies were obtained and evaluated via the upgraded Sydney system, whereas visible gastric events and status of the gastric mucosa were evaluated via a 0–3 rating scale. During both studies, patients recorded gastric symptoms in a daily symptom diary. Results In the ENGORD study, patients who received the potentiated clinoptilolite reported a significant reduction (P≤0.05) in severity of symptoms including reduction in heartburn (44%), discomfort (54%), and pain (56%). Symptom-free days improved by 41% compared to the group who received placebo (not significant). This was over and above the benefits seen with the proton pump inhibitor. In the NSAID study, the reduction in gastric symptom severity was echoed in the group who received the potentiated clinoptilolite. Treatment with the potentiated clinoptilolite resulted in significant prevention (P≤0.05) of mucosal erosion severity as graded by the gastroenterologist. Conclusion Absorbatox is a

    Background Zegerid (on demand immediate-release omeprazole and sodium bicarbonate combination therapy) has demonstrated earlier absorption and more rapid pH change compared with Losec (standard enteric coated omeprazole), suggesting more rapid clinical relief of heartburn. This Phase III, multicenter, double-blind, double-dummy, randomized study assessed the clinical superiority of Zegerid versus Losec for rapid relief of heartburn associated with gastro-esophageal reflux disease (GERD). Methods Patients with a history of frequent (2 3 days/week) uncomplicated GERD, were randomized to receive Zegerid (20mg) or Losec (20mg) with corresponding placebo. Study medication was self-administered on the first episode of heartburn, and could be taken for up to 3 days within a 14 day study period. Heartburn severity was self assessed up to 180 minutes post dose (9 point Likert scale). Primary endpoint was median time to sustained response (≥3 point reduction in heartburn severity for ≥45 minutes). Results Of patients randomized to Zegerid (N=122) or Losec (N=117), 228/239 had recorded ≥1 evaluable heartburn episodes and were included in the modified intent-to-treat population. No significant between-group differences were observed for median time to sustained response (60.0 vs. 52.2 minutes, Zegerid [N=117] and Losec [N=111], respectively), sustained partial response (both, 37.5 minutes) and sustained total relief (both, 105 minutes). Significantly more patients treated with Zegerid reached sustained total relief within 0–30 minutes post dose in all analysis sets (p<0.05). Both treatments were well tolerated and did not raise any safety concerns. Conclusions Superiority of Zegerid over Losec for rapid heartburn relief was not demonstrated; both treatments were equally effective however the rapid onset of action of Losec was unexpected. Factors, including aspects of study design may have contributed to this. This study supports previously reported difficulty in

    The matrix metalloproteinase (MMP) family of proteins mediates various cellular pathways, including apoptosis and angiogenesis. Polymorphisms of MMP genes are associated with increased esophageal adenocarcinoma (EAC) risk. Gastroesophageal reflux disease (GERD) is an established EAC risk factor. We examined whether MMP polymorphism-EAC risk is modified by GERD. In total, 309 EAC patients and 279 frequency-matched healthy controls underwent MMP1 1G/2G, MMP3 6A/5A, MMP12 -82A/G and MMP12 1082A/G genotyping. Questionnaires collected GERD history. EAC risk was analyzed using logistic regression, adjusted for key covariates and stratified by GERD. Joint effects models explored GERD severity and duration, whereas additional models explored genotype-GERD interactions in EAC risk. We determined that each MMP1 and MMP3 minor (variant) allele was independently associated with increased EAC risk (adjusted odds ratio (AOR) 3.2, 95% confidence interval (CI) 2.0-5.1, p < 0.001 and AOR 1.8, 95% CI 1.1-2.7, p = 0.01, respectively) only among those with GERD but not in GERD-free individuals (all p = nonsignificant). There were significant interactions between the MMP1 variants and the presence of GERD (p = 0.002) and between MMP3 variants and GERD (p = 0.04). There was an equally strong interaction between cumulative GERD severity and MMP1 (p = 0.002). The AOR of each variant allele was 14.9 (95% CI 1.6-136) for individuals with severe GERD, 1.7 (95% CI 1.0-2.7) for mild-moderate GERD and 0.98 (95% CI 0.7-1.4) for those without GERD. This was further reflected in separate analyses of frequency and duration of GERD. In conclusion, MMP1 1G/2G (and possibly MMP3 6A/5A) polymorphisms alter EAC risk differentially for GERD and GERD-free individuals.

    Introduction  The Gastroesophageal Reflux Disease has a prevalence of ∼12% of the urban population in Brazil. Koufman proposed the term to designate Laryngeal Pharyngeal Reflux (LPR) symptoms, signs or tissue damage resulting from aggression of the gastrointestinal contents in the upper aerodigestive tract. Belafsky et al proposed a score that points to inflammatory laryngeal signs through videolaryngoscopic findings, the Reflux Finding Score (RFS). Moreover, in 2002, they published the Reflux Symptom Index (RSI). Objective  The objective of this study is to provide a comparison between the Reflux Finding Score and the Reflux Symptom Index in the practice of Otorhinolaryngology. Methods  Our study involved a total of 135 patients who visited the Ear, Nose, and Throat (ENT) clinic Núcleo de Otorrinolaringologia e Cirurgia de Cabeça e Pescoço de São Paulo between April 2014 and May 2015 with suspected LPR. We excluded nine patients and the study group was 126 patients. All patients were ranked by their RSI and RFS scores. Results  The study group consisted of 126 patients (88 women and 38 men). Their main complaints were cough (40.4%), globus (21.4%), dysphonia (19.8%), throat clearing (15.8%), postnasal drip (3.17%), snoring (1.5%), dysphagia (1.5%), cacosmia (0.7%), and regurgitation (1.5%). The RSI ranges from 13 to 42 with a mean of 20.7 (SD = 6.67). The RFS ranged from 3 to 19 with a mean of 9.53 (SD = 2.64). Conclusion  The RSI and RFS can easily be included in ENT routines as objective parameters, with low cost and high practicality. Based on the clinical index, the specialist can evaluate the need for further tests. PMID:27413402

    2016-01-01

    summary An important underlying mechanism that contributes to autoimmunity is the loss of inhibitory signaling in the immune system. Sialic acid-recognizing Ig superfamily lectins or Siglecs are a family of cell surface proteins largely expressed in hematopoietic cells. The majority of Siglecs are inhibitory receptors expressed in immune cells that bind to sialic acid containing ligands and recruit SH2-domain containing tyrosine phosphatases to their cytoplasmic tails. They deliver inhibitory signals that can contribute to the constraining of immune cells and thus protect the host from autoimmunity. The inhibitory functions of CD22/Siglec-2 and Siglec-G and their contributions to tolerance and autoimmunity, primarily in the B lymphocyte context, are considered in some detail in this review. The relevance to autoimmunity and unregulated inflammation of modified sialic acids, enzymes that modify sialic acid, and other sialic acid binding proteins are also reviewed. PMID:26683151

    Gastroesophageal reflux disease (GORD) represents an illness which reflects a syndrome caused by returning of acid gastric, alkaline pancreatic and bowels content into the oesophagus, which is in the stomach, because of the protective mechanisms of oesophageal loss. The aim of this study was that this prospective study should explain the role of Helicobacter pylori infection in modification of GORD, respectively whether the Helicobacter pylori infection acts protectively or by deterioration of the disease. According to the settled rules, the inquiry was performed as well as the selection of 97 candidates to undergo research in this study. Helicobacter pylori infection has been proved by immunoassay in all pts in the beginning of this study. Endoscopy has been performed in all pts, the degree of gastroesophageal reflux disease by Sawary-Miller was done. The main group consisted of 50 candidates in whom the eradication of Helicobacter pylori infection was done with triple therapy, pantoprazol + amoxycilin + klaritromicin, which was proven by an immunoassay test. Two groups of pts were formed: the main one with eradicated Helicobacter infection, and a controlled one with a Helicobacter positive infection, which was subject to modification of life style. During 12 months, this study consisted of endoscopic evaluations and monthly evaluation of pts daily difficulties. The eradication of Helicobacter pylori infection acts on the improvement of gastroesophageal disease course by improvement of endoscopic findings by Sawary-Miller, and by decreasing daily acid symptoms. The eradication of Helicobacter pylori infection in gastroesophageal reflux disease does it act at the symptoms such as heartburn, weekly acid symptoms and chest pain.

    The most common type of esophageal dysfunction associated with chest pain is gastroesophageal reflux, which may be induced by exercise. The effect of exercise on esophageal function has mainly been investigated in normal subjects or trained athletes. Few studies have investigated exercise and esophageal motility disorders. One hundred and thirty-five patients underwent ambulatory esophageal manometry and pH monitoring, before, during and immediately after moderate exercise. Patients were divided into four groups: Normal, nutcracker, diffuse spasm and gastroesophageal reflux disease (GERD). Ambulatory manometry and pH were monitored while exercising on a treadmill during which standardized boluses of water were administered. Nutcracker and diffuse spasm patients demonstrated a significant fall in esophageal wave amplitude during exercise compared to controls, which returned rapidly to pre exercise values after resting. There was no evidence of acid reflux in the non-reflux groups during exercise. Reflux was noted in 13 patients with GERD during exercise, none of whom had evidence of reflux at the onset of exercise. When these patients were classified by reflux type, the majority, 11 patients, were found to come from the combined or supine reflux group. Esophageal amplitude in nutcracker esophagus does not increase during moderate exercise. Moderate exercise provokes reflux in GERD patients with combined or supine reflux.

    Cardioceuticals are nutritional supplements that contain all the essential nutrients including vitamins, minerals, omega-3-fatty acids and other antioxidants like a-lipoic acid and coenzyme Q10 in the right proportion that provide all round protection to the heart by reducing the most common risks associated with the cardiovascular disease including high low-density lipoprotein cholesterol and triglyceride levels and factors that contribute to coagulation of blood. Omega-3 fatty acids have been shown to significantly reduce the risk for sudden death caused by cardiac arrhythmias and all-cause mortality in patients with known coronary heart disease. Omega-3 fatty acids are also used to treat hyperlipidemia and hypertension. There are no significant drug interactions with omega-3 fatty acids. The American Heart Association recommends consumption of two servings of fish per week for persons with no history of coronary heart disease and at least one serving of fish daily for those with known coronary heart disease. Approximately 1 g/day of eicosapentaenoic acid plus docosahexaenoic acid is recommended for cardio protection. Higher dosages of omega-3 fatty acids are required to reduce elevated triglyceride levels (2-4 g/day). Modest decreases in blood pressure occur with significantly higher dosages of omega-3 fatty acids.

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

    Purpose This study was performed to evaluate the quality of sleep in snoring obese children without obstructive sleep apnea (OSA); and to study the possible relationship between sleep interruption and gastroesophageal reflux (GER) in snoring obese children. Methods Study subjects included 13 snoring obese children who were referred to our sleep lab for possible sleep-disordered breathing. Patients underwent multichannel intraluminal impedance and esophageal pH monitoring with simultaneous polysomnography. Exclusion criteria included history of fundoplication, cystic fibrosis, and infants under the age of 2 years. Significant association between arousals and awakenings with previous reflux were defined by symptom-association probability using 2-minute intervals. Results Sleep efficiency ranged from 67-97% (median 81%). A total of 111 reflux episodes (90% acidic) were detected during sleep, but there were more episodes per hour during awake periods after sleep onset than during sleep (median 2.3 vs. 0.6, p=0.04). There were 279 total awakenings during the sleep study; 56 (20.1%) of them in 9 patients (69.2%) were preceded by reflux episodes (55 acid, 1 non-acid). In 5 patients (38.5%), awakenings were significantly associated with reflux. Conclusion The data suggest that acid GER causes sleep interruptions in obese children who have symptoms of snoring or restless sleep and without evidence of OSA. PMID:27066445

    Oesophageal pH-impedance monitoring allows detection of acid and non-acid gastro-oesophageal reflux (GOR) events. Visual analysis of impedance recording requires expertise. Our aim was to evaluate the efficacy of an automated analysis for GOR assessment. Seventy-three patients with suspected GORD underwent 24-h oesophageal pH-impedance monitoring. Recordings analysis was performed visually (V) and automatically using Autoscan function (AS) of Bioview software. A symptom index (SI) > or =50% was considered for a significant association between symptoms and reflux events. AS analysis detected more reflux events, especially non-acid, liquid, pure gas and proximal events. Detection of oesophageal acid exposure and acid reflux events was similar with both analyses. Agreement between V and AS analysis was good (Kendall's coefficient W > 0.750, P < 0.01) for all parameters. During pH-impedance studies, 65 patients reported symptoms. As compared to visual analysis, the sensitivity and specificity of a positive SI determined by AS were respectively 85.7% and 80% for all reflux events, 100% and 98% for acid reflux and 33% and 87.5% for non-acid reflux. Despite good agreement with visual analysis, automatic analysis overestimates the number of non-acid reflux events. Visual analysis remains the gold standard to detect an association between symptoms and non-acid reflux events.

    Description of the reflux nephropathy. Pyelonephritis lesions are undoubtedly linked to the vesico-ureteric reflux. The role of the intra-renal reflux ( Hodson ) and the Big Bang Theory ( Ransley ) are discussed as the data from animal experiments. The role of the sterile reflux and of the segmental hypoplasia is relatively less important. The actual management of vesico-ureteric reflux treatment is questioned.

    The aim of this study was to evaluate the effect of liver diseases of different etiologies and clinical severity of liver cirrhosis on the serum level of hyaluronic acid. The results were compared with noninvasive markers of liver fibrosis: APRI, GAPRI, HAPRI, FIB-4 and Forn's index. Serum samples were obtained from 20 healthy volunteers and patients suffering from alcoholic cirrhosis (AC)-57 patients, non-alcoholic cirrhosis (NAC)-30 and toxic hepatitis (HT)-22. Cirrhotic patients were classified according to Child-Pugh score. Hyaluronic acid concentration was measured by the immunochemical method. Non-patented indicators were calculated using special formulas. The mean serum hyaluronic acid concentration was significantly higher in AC, NAC and HT group in comparison with the control group. There were significant differences in the serum hyaluronic acid levels between liver diseases, and in AC they were significantly higher than those in NAC and HT group. The serum hyaluronic acid level differs significantly due to the severity of cirrhosis and was the highest in Child-Pugh class C. The sensitivity, specificity, accuracy, positive and negative predictive values and the area under the ROC curve for hyaluronic acid and all non-patented algorithms were high and similar to each other. We conclude that the concentration of hyaluronic acid changes in liver diseases and is affected by the severity of liver cirrhosis. Serum hyaluronic acid should be considered as a good marker for noninvasive diagnosis of liver damage, but the combination of markers is more useful.

    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.

    The hydrophilic bile acid ursodeoxycholic acid has recently been shown to reduce biochemical markers of both cholestasis and hepatocellular damage in patients with chronic liver diseases. The most compelling evidence available is for chronic cholestatic liver diseases, in particular primary biliary cirrhosis, primary sclerosing cholangitis, and cholestasis associated with cystic fibrosis. The effects may be less beneficial in patients with advanced liver disease from these conditions. Data from placebo controlled trials are now available in support of earlier uncontrolled observations, but it is not yet clear whether short term benefit results in an improvement in longterm prognosis. The mechanism of action of the compound seems to reside in its displacement of toxic hydrophobic bile acids from both the bile acid pool and hepatocellular membranes. There may be an independent effect on bile flow, which could be of particular importance in cystic fibrosis, and possibly an effect on the immune system. Ursodeoxycholic acid should now be regarded as occupying a central place in the medical management of chronic cholestatic liver diseases, in particular primary biliary cirrhosis, because it improves cholestasis and reduces hepatocellular damage and it is not toxic. Research should now be targeted on whether treatment with ursodeoxycholic acid, initiated early in cholestatic liver conditions, improves the long-term outcome. PMID:1916492

    The combination of urinary tract infection (UTI) and vesicoureteral reflux (VUR) is commonly thought to predispose the child to pyelonephritis, renal scarring and, later in life, to hypertension or end-stage renal disease (ESRD). This paradigm has led to the active search, follow-up and treatment of VUR, and also prevention of recurrent UTI in children. The causality of VUR and ESRD is controversial, however. According to recent meta-analyses it is uncertain whether we can prevent renal scarring or ESRD by treating VUR. Studies on VUR are abundant, but the findings and conclusions are confounding. Because of the lack of evidence of the role of VUR, reasonable doubt has recently been presented on the rationale of imaging all children with UTI and treating the children with VUR. The overall importance of VUR is confounded because of the natural tendency of VUR to resolve spontaneously, its dynamic nature, and its different grades in children. The historical studies showing that VUR is much more common, even among healthy children, than usually claimed, have been forgotten. Since it seems that we are referring too many healthy children to unpleasant and possibly unnecessary imaging tests for VUR, we are uncertain when and what kind of VUR-if any-we should treat, and whether our present rationale of addressing VUR truly makes any difference to renal scarring or ESRD in children, we should critically revisit the subject of VUR.

    Vesicoureteral reflux (VUR) is the retrograde passage of urine from the bladder to the upper urinary tract. It is the most common congenital urological anomaly affecting 1-2% of children and 30-40% of patients with urinary tract infections. VUR is a major risk factor for pyelonephritic scarring and chronic renal failure in children. It is the result of a shortened intravesical ureter with an enlarged or malpositioned ureteric orifice. An ectopic embryonal ureteric budding development is implicated in the pathogenesis of VUR, which is a complex genetic developmental disorder. Many genes are involved in the ureteric budding formation and subsequently in the urinary tract and kidney development. Previous studies demonstrate an heterogeneous genetic pattern of VUR. In fact no single major locus or gene for primary VUR has been identified. It is likely that different forms of VUR with different genetic determinantes are present. Moreover genetic studies of syndromes with associated VUR have revealed several possible candidate genes involved in the pathogenesis of VUR and related urinary tract malformations. Mutations in genes essential for urinary tract morphogenesis are linked to numerous congenital syndromes, and in most of those VUR is a feature. The Authors provide an overview of the developmental processes leading to the VUR. The different genes and signaling pathways controlling the embryonal urinary tract development are analyzed. A better understanding of VUR genetic bases could improve the management of this condition in children. PMID:27013925

    AIM: To determine associations between enterogastric bile reflux and gastric mucosal pathology. METHOD: A retrospective study using fasting gastric juice bile acid measurements and antral or prestomal biopsy specimens from 350 patients, 66 of whom had previously undergone surgery that either bypassed or disrupted the pyloric sphincter. RESULTS: Bile reflux was positively associated with reactive gastritis and negatively with Helicobacter pylori density. After stratification for previous surgery, age, and H pylori status, the histological feature most strongly associated with bile reflux was intestinal metaplasia, including all its subtypes. The prevalence of intestinal metaplasia was greatest in patients with both H pylori infection and high bile acid concentrations. Bile reflux was also positively associated with the severity of glandular atrophy, chronic inflammation, lamina propria oedema and foveolar hyperplasia. CONCLUSIONS: Bile reflux is a cause of reactive gastritis. It modifies the features of H pylori associated chronic gastritis. The changes are not confined to patients who have had surgery to their stomachs. The positive associations with atrophy and intestinal metaplasia have implications for models of gastric carcinogenesis. Images PMID:8463417

    BACKGROUND: One of the major pathophysiological abnormalities in patients with gastro-oesophageal reflux disease is thought to involve transient lower oesophageal sphincter (LOS) relaxations. One component of the neural mechanism controlling the LOS appears to be a reflex are whose afferent limb originates in the gastric fundus. As inflammation is known to be associated with neural activation an investigation was made to determine whether gastric infection with H pylori is altered in prevalence or distribution in patients with reflux disease. METHODS: Five groups of subjects referred for endoscopy-group 1: 25 controls (asymptomatic individuals with anaemia and normal endoscopy); group 2: 36 subjects with erosive oesophagitis alone (Savary-Millar grades I-III); group 3: 16 subjects with duodenal ulcer alone; group 4: 15 subjects with oesophagitis with duodenal ulcer; group 5: 16 subjects with Barrett's oesophagus. No patients were receiving acid suppressants or antibiotics. An antral biopsy specimen was taken for a rapid urease test, and two biopsy specimens were taken from the antrum, fundus, and oesophagus (inflamed and non-inflamed) for histological evidence of inflammation and presence of H pylori using a Giemsa stain. RESULTS: Nine (36%) controls had H pylori. Patients with duodenal ulcer alone had a significantly higher incidence of colonisation by H pylori than other groups (duodenal ulcer 15 (94%); oesophagitis 13 (36%); oesophagitis+duodenal ulcer 6 (40%); Barrett's oesophagus 4 (25%)). H pylori was not more common in oesophagitis. When H pylori colonised the gastric antrum it was usually found in the gastric fundus. There was no difference in anatomical distribution of H pylori in the different patient groups. In Barrett's oesophagus H pylori was found in two of 16 in the metaplastic epithelium. CONCLUSION: H pylori is not more common and its distribution does not differ in those with oesophagitis compared with control subjects, and is therefore unlikely

    Uric acid is the product of purine metabolism. It is known that hyperuricemia, defined as high levels of blood uric acid, is the major etiological factor of gout. A number of epidemiological reports have increasingly linked hyperuricemia with cardiovascular and neurological diseases. Studies highlighting the pathogenic mechanisms of uric acid point to an inflammatory response as the primary mechanism for inducing gout and possibly contributing to uric acid's vascular effects. Monosodium urate (MSU) crystals induce an inflammatory reaction, which are recognized by Toll-like receptors (TLRs). These TLRs then activate NALP3 inflammasome. MSU also triggers neutrophil activation and further produces immune mediators, which lead to a proinflammatory response. In addition, soluble uric acid can also mediate the generation of free radicals and function as a pro-oxidant. This review summarizes the epidemiological studies of hyperuricemia and cardiovascular disease, takes a brief look at hyperuricemia and its role in neurological diseases, and highlights the studies of the advanced pathological mechanisms of uric acid and inflammation.

    Background/Aims We aim to evaluate the efficacy and safety of combination therapy in erosive reflux disease (ERD) patients by comparing endoscopic healing rates according to the Los Angeles classification for esomeprazole alone, and esomeprazole plus mosapride. Methods A total of 116 ERD patients were randomized to receive esomeprazole 40 mg once daily plus mosapride 5 mg 3 times daily (E+M group), or esomeprazole plus placebo (E only group) for 8 weeks. Patients recorded gastroesophageal reflux disease (GERD) symptom questionnaire at weeks 4 and 8. The primary endpoint was the endoscopic healing rate of ERD after 8 weeks of treatment. Results Endoscopic healing rates according to the Los Angeles classification was 32 (66.7%) in the E+M group and 26 (60.5%) in the E only group, but there was no statistically significant difference between the groups. Only at 4 weeks, the total GERD symptom score changes relative to the baseline significantly improved in the E+M group than that of the E only group (−13.4 ± 14.7 vs −8.0 ± 12.3, P = 0.041), and upper abdominal pain and belching score changes showed significantly improved in the E+M group than that of the E only group (P = 0.018 and P = 0.013, respectively). Conclusions The combination of a proton pump inhibitor with mosapride shows a tendency for upper abdominal pain, belching, and total GERD symptoms scores to improve more rapidly. This suggests that combination therapy with esomeprazole and mosapride will be useful for rapid improvement of specific GERD symptoms, such as upper abdominal pain and belching in ERD patients.

    The several types of neoplastic transformations are accompanied by alterations in the composition of cell glycoproteins, which are major structural components of cell surfaces. One such observed alteration is in the level of sialic acid on the cell surface. In the present investigation, plasma sialic acid levels were measured in normal volunteers and neoplastic patients using thiobarbituric acid spectrophotometric methods. The mean plasma sialic acid level from 124 normal volunteers was 3.0 mumol/ml. The mean for 20 non-malignant patients was 3.2 mumol/ml. Such observed mean values of sialic acid were 3.7 mumol/ml in 64 breast cancer patients, 5.1 mumol/ml in 22 lung cancer patients, 4.1 mumol/ml in 20 colon patients, and 5.0 mumol/ml in 26 patients having ovarian, cervix, pancreas, prostate, thyroid, uterine, squamous cell, esophageal and endometrial cancers. Serial determinations of plasma sialic acid in 15 patients correlated well with the progression and regression of disease. These results indicate that plasma sialic acid levels are elevated over control levels in the different types of cancer patients studied. Assay of plasma sialic acid is not sensitive enough to be used for screening, but could be used as a prognostic determinant in a variety of neoplastic conditions.

    Gastroesophageal scintigraphy is a quantitative technique that can be employed to detect and quantitate gastroesophageal reflux before and after the application of therapeutic modalities, including change in body position, bethanechol, atropine, antacids, and antacid-alginate compounds. Five groups of 10-15 patients each were studied before and after using each therapeutic modality and before and after atropine. The results were compared to the patient's symptomatology and to the acid reflux test. Gastroesophageal scintigraphy was performed following oral administration of 300 microCi 99mTc-sulfur colloid in 300 ml acidified orange juice. Thirty-second gamma camera images were obtained as the gastroesophageal gradient was increased from approximately 10 to 35 mm Hg at 5 mm Hg increments using an inflatable abdominal binder. Data were processed using a digital computer. Reflux was reduced by change in position from recumbent to upright, and by the use of subcutaneous bethanechol, oral antacid, or oral antacidalginate compound. Atropine increased reflux. Gastroesophageal scintigraphy is more sensitive than fluoroscopy, correlates well with clinical symptomatology, and is a reliable and convenient technique for the quantitative estimation of reflux before and after therapy.

    Prolonged diffuse laryngeal inflammation from smoking and/or reflux is commonly diagnosed as chronic laryngitis and treated empirically with expensive drugs that have not proven effective. Shifts in microbiota have been associated with many inflammatory diseases, though little is known about how resident microbes may contribute to chronic laryngitis. We sought to characterize the core microbiota of disease-free human laryngeal tissue and to investigate shifts in microbial community membership associated with exposure to cigarette smoke and reflux. Using 454 pyrosequencing of the 16S rRNA gene, we compared bacterial communities of laryngeal tissue biopsies collected from 97 non-treatment-seeking volunteers based on reflux and smoking status. The core community was characterized by a highly abundant OTU within the family Comamonadaceae found in all laryngeal tissues. Smokers demonstrated less microbial diversity than nonsmokers, with differences in relative abundances of OTUs classified as Streptococcus, unclassified Comamonadaceae, Cloacibacterium, and Helicobacter. Reflux status did not affect microbial diversity nor community structure nor composition. Comparison of healthy laryngeal microbial communities to benign vocal fold disease samples revealed greater abundance of Streptococcus in benign vocal fold disease suggesting that mucosal dominance by Streptococcus may be a factor in disease etiology.

    Inflammation is overall a protective response, whose main goal is to liberate the human being of cellular lesions caused by micro-organisms, toxins, allergens, etc., as well as its consequences, and of death cells and necrotic tissues. Chronic inflammation, which is detrimental to tissues, is the basic pathogenic mechanism of hypersensitivity reactions against xenobiotics. Other frequent pathologies, for instance atherosclerosis, chronic hepatitis, inflammatory bowel disease (IBD), liver cirrhosis, lung fibrosis, psoriasis, and rheumatoid arthritis are also chronic inflammatory diseases. Chemical mediators of inflammation are derived from blood plasma or different cell-type activity. Biogenic amines, eicosanoids and cytokines are within the most important mediators of inflammatory processes. The different activities of eicosanoids derived from arachidonic acid (20:4 n-6) versus those derived from eicosapentaenoic acid (20:5 n-3) are one of the most important mechanisms to explain why n-3, or omega-3, polyunsaturated fatty acids (PUFA) exhibit anti-inflammatory properties in many inflammatory diseases. Dietary supplements ranging 1-8 g per day of n-3 PUFA have been reportedly beneficial in the treatment of IBD, eczema, psoriasis and rheumatoid arthritis. In addition, recent experimental studies in rats with experimental ulcerative colitis, induced by intrarectal injection of trinitrobenzene sulphonic acid, have documented that treatment with n-3 long-chain PUFA reduces mucosal damage as assessed by biochemical and histological markers of inflammation. Moreover, the defence antioxidant system in this model is enhanced in treated animals, provided that the n-3 PUFA supply is adequately preserved from oxidation.

    MR urography has the potential to significantly improve our understanding of the relationship between reflux nephropathy, pyelonephritis, vesicoureteric reflux and renal dysplasia. MR urography utilizes multiple parameters to assess both renal anatomy and function and provides a more complete characterization of acquired and congenital disease. Pyelonephritis and renal scarring can be distinguished by assessing the parenchymal contours and signal intensity. Characteristic imaging features of renal dysplasia include small size, subcortical cysts, disorganized architecture, decreased and patchy contrast enhancement as well as a dysmorphic pelvicalyceal system. Because of its ability to subdivide and categorize this heterogeneous group of disorders, it seems inevitable that MR urography will replace DMSA renal scintigraphy as the gold standard for assessment of pyelonephritis and renal scarring. MR urography will contribute to our understanding of renal dysplasia and its relationship to reflux nephropathy.

    Comprehensive guidelines for the diagnosis and management of gastro-esophageal reflux (GER) and GER disease (GERD) were developed by the European and North American Societies for Pediatric Gastroenterology, Hepatology and Nutrition. GERD is reflux associated with troublesome symptoms or complications. The recognition of GER and GERD is relevant to implement best management practices. A conservative management is indicated in infants with uncomplicated physiologic reflux. Children with GERD may benefit from further evaluation and treatment. Since the publications of the European and North American Societies for Pediatric Gastroenterology, Hepatology and Nutrition guidelines in 2009, no important novelties in drug treatment have been reported. Innovations are mainly restricted to the management of regurgitation in infants. During the last 5 years, pros and cons of multichannel intraluminal impedance have been highlighted. However, overall 'not much has changed' in the diagnosis and management of GER and GERD in infants and children.

    Raw materials and pollution control are key issues for the ethanol fermentation industry. To address these concerns, food waste was selected as fermentation substrate, and stillage reflux was carried out in this study. Reflux was used seven times during fermentation. Corresponding ethanol and reducing sugar were detected. Accumulation of by-products, such as organic acid, sodium chloride, and glycerol, was investigated. Lactic acid was observed to accumulate up to 120g/L, and sodium chloride reached 0.14mol/L. Other by-products did not accumulate. The first five cycles of reflux increased ethanol concentration, which prolonged fermentation time. Further increases in reflux time negatively influenced ethanol fermentation. Single-factor analysis with lactic acid and sodium chloride demonstrated that both factors affected ethanol fermentation, but lactic acid induced more effects.

    Proton pump inhibitors (PPI) are efficient for ex juvantibus diagnostics of non-coronary chest pain (NCCP) of gastroesophageal reflux origin as well as for its course treatment. The aim of this randomized cross-over study was to compare the efficiency of rabeprasol and omeprasol as means of both diagnostics and long-term treatment. In rabeprasol group the symptoms disappeared more quickly, and the maximum effect was achieved by day three, while in omeprasol group the best results were achieved only by day six (p < or = 0.05). The sensitivity and specificity of rabeprasol test was 81.6% and 80.6%, respectively, while those of omeprasol test were 73.5% and 77.4%, respectively. By the end of the 12th week of treatment pain syndrome had been completely or partly coped with in 92% of rabeprasol patients, and 76% of omeprazol patients (p < 0.05). Thus, response to rabeprasol takes place twice as quick as response to omeprasol, which makes it possible to shorten the time of NCCP diagnostics. Furthermore, rabeprasol test is more sensitive and specific. Course treatment with high doses of PPI increase the number of patients with eliminated pain syndrome, and rabeprasol here is more efficient than omeprasol.

    Gastroesophageal reflux is a common phenomenon in infants, but the differentiation between gastroesophageal reflux and gastroesophageal reflux disease can be difficult. Symptoms are non-specific and there is increasing evidence that the majority of symptoms may not be acid-related. Despite this, gastric acid inhibitors such as proton pump inhibitors are widely and increasingly used, often without objective evidence or investigations to guide treatment. Several studies have shown that these medications are ineffective at treating symptoms associated with reflux in the absence of endoscopically proven oesophagitis. With a lack of evidence for efficacy, attention is now being turned to the potential risks of gastric acid suppression. Previously assumed safety of these medications is being challenged with evidence of potential side effects including GI and respiratory infections, bacterial overgrowth, adverse bone health, food allergy and drug interactions.

    Incidence of reflux esophagitis(RE) has increased over the past 10 years in Japan, where aging of the population is rapidly progressing. The majority(73.6%) of the patients with RE consisted of non-elderly males having life style problems and of elderly females suffering from posture alterations. This suggested the importance of the disease onset among elderly female population in addition to that of the non-elderly male population. The risk factors specific to the elderly patients include not only persistent acid secretion and presbyesophagus, but also complication with orthopedic regression diseases with posture changes and osteoporosis. The association with the latter orthopedic regression diseases has been significantly increasing and is suggested to promote development of RE. Further increase in the prevalence of RE is foreseen in this aging-accelerating country.

    Cognitive decline in the elderly, particularly Alzheimer's disease (AD), is a major socio-economic and healthcare concern. We review here the literature on one specific aspect of diet affecting AD, that of the omega3 fatty acids, particularly the brain's principle omega3 fatty acid - docosahexaenoic acid (DHA). DHA has deservedly received wide attention as a nutrient supporting both optimal brain development and for cardiovascular health. Our aim here is to critically assess the quality of the present literature as well as the potential of omega3 fatty acids to treat or delay the onset of AD. We start with a brief description of cognitive decline in the elderly, followed by an overview of well recognized biological functions of DHA. We then turn to epidemiological studies, which are largely supportive of protective effects of fish and DHA against risk of AD. However, biological studies, including blood and brain DHA analyses need careful interpretation and further investigation, without which the success of clinical trials with DHA may continue to struggle. We draw attention to some of the methodological issues that need resolution as well as an emerging mechanism that may explain how DHA could be linked to protecting brain function in the elderly.

    Twenty-three patients with intractable gastro-oesophageal reflux were treated by insertion of the Angelchik antireflux prosthesis. Good symptomatic relief was achieved in over 80% of patients reviewed up to 28 months after operation and there was marked resolution of oesophagitis as seen on endoscopy. Oesophageal manometry and pH studies performed preoperatively and at 3 and 12 months after operation, showed a significant increase in lower oesophageal sphincter pressure with decreased acid reflux. Some technical problems were encountered, but the prosthesis is potentially a simple and effective means of controlling gastro-oesophageal reflux. Images Fig. 1 PMID:4051424

    In the present work, Pt nanoparticles were produced from a reaction mixture containing a trace amount of cobalt carbonyl salt acting as a shape inducer. Nanoparticle shape evolution during reaction mixture reflux was monitored by characterizing particles extracted from the reaction mixture at different times. It was observed that 5 min of reflux produced spherical nanoparticles, 30 min of reflux produced cube shaped nanoparticles, and 60 min of reflux produced truncated octahedron morphology nanoparticles. It is illustrated that during nanoparticle synthesis the reflux process can provide energy needed for shape transformation from a metastable cube morphology to a truncated octahedron morphology which is thermodynamically the most stable geometry for fcc crystals. An optimization of the reaction reflux is thus needed for isolating metastable shapes.

    OBJECTIVE: To review current understanding and approach to diseases resulting from gastroesophageal reflux (GER) in infants and children. QUALITY OF EVIDENCE: Very few randomized or blinded controlled trials have been reported in this area. MEDLINE searches for gastroesophageal reflux, gastroesophageal reflux disease, esophagitis, and pulmonary aspiration, using age-limited (all childhood) data, find most articles. Very thorough reviews undertaken by both European and North American societies for pediatric gastroenterology provide up-to-date consensus statements. MAIN MESSAGE: Gastroesophageal reflux is a normal phenomenon recognized in infants as "spitting up." Understanding the mechanism of transient lower esophageal relaxation episodes allows physicians to counsel concerned parents that reflux and spitting up occur universally, but are less visible in children older than 6 to 12 months. In infants and children, GER can result in a variety of diseases and can cause esophageal and tracheopulmonary damage. Investigation of these diseases can be specific and accurate. Therapy is available, but no drug will stop reflux. Some children suffer intractable GER with secondary complications (GERD) despite medical treatment. Failure of therapy could mean patients require surgical intervention. CONCLUSION: Visible GER is very common in infants and children and can usually be managed with explanation, reassurance, and simple measures. Diseases caused by GER can be investigated specifically and managed with accurately defined therapy. PMID:11723599

    This review summarizes recent published literature on the association between serum uric acid and cardiovascular disease, a relationship which is complex and not fully elucidated. Uric acid may be a marker for risk, a causative agent in cardiovascular disease, or both. Various biologic factors can influence serum uric acid levels, and serum uric acid level itself is closely related to conditions such as hypertension, dyslipidemia, obesity, and impaired glucose metabolism, that contribute to cardiovascular disease pathophysiology. Serum uric acid levels have been found to be associated with adverse outcomes, including mortality, in the general population. In addition, serum uric acid is associated with increased risk for incident coronary heart disease, heart failure, and atrial fibrillation. In the setting of established systolic heart failure, serum uric acid is positively associated with disease severity and mortality risk. Whether targeting treatment based on uric acid levels might affect clinical outcomes is still being studied.

    Vesicoureteric reflux (VUR) is a common congenital defect of the urinary tract that is usually discovered after a child develops a urinary tract infection. It is associated with reflux nephropathy, a renal lesion characterized by the presence of chronic tubulointersitial inflammation and fibrosis. Most patients are diagnosed with reflux nephropathy after one or more febrile urinary tract infections, suggesting a potential role for infection in its development. We have recently shown that the C3H mouse has a 100% incidence of VUR. Here, we evaluate the roles of VUR and uropathogenic Escherichia coli infection in the development of reflux nephropathy in the C3H mouse. We find that VUR in combination with sustained kidney infection is crucial to the development of reflux nephropathy, whereas sterile reflux alone fails to induce reflux nephropathy. A single bout of kidney infection without reflux fails to induce reflux nephropathy. The host immune response to infection was examined in two refluxing C3H substrains, HeN and HeJ. HeJ mice, which have a defect in innate immunity and bacterial clearance, demonstrate more significant renal inflammation and reflux nephropathy compared with HeN mice. These studies demonstrate the crucial synergy between VUR, sustained kidney infection and the host immune response in the development of reflux nephropathy in a mouse model of VUR.

    Background: Gastroesophageal reflux disease (GERD) is a chronic disorder,and although effective short-term treatment strategies are known, the rate of relapse within 1 year is as high as 90% despite successful acute treatment. Consequently, most patients with GERD require an effective long-term management strategy to achieve adequate symptom control and maintain mucosal healing. Objective: The present study was undertaken to compare the control ofGERD symptoms during long-term (24-week) treatment with pantoprazole 20 mg used on-demand or continuously in patients with mild GERD after complete relief of acute GERD symptoms. Methods: Patients with endoscopically confirmed Savary/Miller grade 0(normal mucosa) or I (patchy red lesions without white coating or with central white coating) GERD were enrolled in this multinational, multicenter study comprising 2 phases. In the first phase, which was open label, patients were treated with pantoprazole 20 mg QD for 4 weeks. The presence and intensity of the symptoms of heartburn, acid regurgitation, and pain on swallowing were assessed. In the second phase, which was an open-label, 24-week, randomized design, only patients completely free of GERD symptoms after acute treatment were included. During this phase, on-demand treatment with pantoprazole 20 mg was directly compared with continuous treatment. The rate of failure to control GERD symptoms after 24 weeks of treatment was estimated using the Kaplan-Meier method. Subsequently, the difference between treatments (on-demand minus continuous) and its 95% CI were calculated, and the on-demand treatment was tested for noninferiority using a predefined noninferiority margin of 20%. The mean daily symptom loads were compared between the treatment groups using the 1-sided Wilcoxon rank sum test on a 5% α level. The point estimate of the difference was determined using the Hodges-Lehman estimator and the 1-sided 95% CI according to Moses. The number of patients unwilling to

    Lysophosphatidic acid (LPA) is a small signaling lipid that is capable of stimulating a plethora of different cellular responses through the activation of its family of cognate G protein-coupled receptors. LPA mediates a wide range of biological effects in many tissue types that have been recently reviewed; however, its effects on vasculature development and function have received comparatively less examination. In this review, literature on the actions of LPA in three main aspects of vascular development (vasculogenesis, angiogenesis, and vascular maturation) is discussed. In addition, evidence for the roles of LPA signaling in the formation of secondary vascular structures, such as the blood brain barrier, is considered, consistent with significant roles for LPA signaling in vascular development, function, and disease.

    Our previous finding of a fractal pattern for gastric pH and esophageal pH plus the statistical association of sequential pH values for up to 2 h led to our hypothesis that the fractal pattern encodes information regarding gastric acidity and that depending on the value of gastric acidity, the esophagus can signal the stomach to alter gastric acidity by influencing gastric secretion of acid or bicarbonate. Under our hypothesis values of gastric pH should provide information regarding values of esophageal pH and vice versa. We used vector autoregression, a theory-free set of inter-related linear regressions used to measure relationships that can change over time, to analyze data from 24-h recordings of gastric pH and esophageal pH. We found that in pH records from normal subjects, as well as from subjects with gastroesophageal reflux disease alone and after treatment with a proton pump inhibitor, gastric pH values provided important information regarding subsequent values of esophageal pH and values of esophageal pH provided important information regarding subsequent values of gastric pH. The ability of gastric pH and esophageal pH to provide information regarding subsequent values of each other was reduced in subjects with gastroesophageal reflux disease compared to normal subjects. Our findings are consistent with the hypothesis that depending on the value of gastric acidity, the esophagus can signal the stomach to alter gastric acidity, and that this ability is impaired in subjects with gastroesophageal reflux disease.

    Folic acid plays an important role in neuroplasticity and in the maintenance of neuronal integrity. Folate is a co-factor in one-carbon metabolism during which it promotes the regeneration of methionine from homocysteine, a highly reactive sulfur-containing amino acid. Methionine may then be converted to S-adenosylmethionine (SAM), the principal methyl donor in most biosynthetic methylation reactions. On the cellular level, folate deficiency and hyperhomocysteinemia exert multiple detrimental effects. These include induction of DNA damage, uracil misincorporation into DNA and altered patterns of DNA methylation. Low folate status and elevated homocysteine increase the generation of reactive oxygen species and contribute to excitotoxicity and mitochondrial dysfunction which may lead to apoptosis. Strong epidemiological and experimental evidence links derangements of one-carbon metabolism to vascular, neurodegenerative and neuropsychiatric disease, including most prominently cerebral ischemia, Alzheimer's dementia and depression. Although firm evidence from controlled clinical trials is largely lacking, B-vitamin supplementation and homocysteine reduction may have a role especially in the primary prevention of stroke and dementia as well as as an adjunct to antidepressant pharmacotherapy.

    Background/Aims Gastroesophageal reflux disease (GERD) is one of the main causes of chronic cough. We evaluated the role of microaspiration in the pathogenesis of reflux-related cough by determining the amount of lipid-laden macrophages (LLMs) in bronchoalveolar lavage (BAL) specimens. Methods A total of 161 cases of chronic cough were evaluated, and 36 patients (average age 48.2 years) were recruited for this single center prospective study. Patients with a history of smoking, angiotensin converting enzyme inhibitor usage, any abnormality on pulmonary function tests, abnormal chest X-rays, occupational or environmental exposures, or upper airway cough syndrome were excluded. GERD was evaluated by 24-hour esophageal impedance-pH monitoring. BAL specimens for LLM determination were obtained from 34 patients by flexible bronchoscopy. Results Patients with pathological intra-esophageal reflux according to multichannel intraluminal impedance and pH monitoring had higher LLM positivity in BAL specimens than patients without pathological reflux (8/14 in reflux positive group vs 1/22 in reflux negative group; P = 0.004). The BAL cell distribution was not different between the 2 groups (P = 0.574 for macrophages, P = 0.348 for lymphocytes, P = 0.873 for neutrophils and P = 0.450 for eosinophils). Conclusions Our results confirm the role of the microaspiration of refluxate in the pathogenetic mechanism of chronic cough. While bronchoscopy is indicated in patients with chronic cough, in addition to the routine airway evaluation, BAL and LLM detection should be performed. LLM can be used to diagnose aspiration in reflux-related chronic cough. Future studies are needed to evaluate the response to anti-reflux medications or surgery in patients with LLM positivity.

    The effect on the blood pressure of experimental vesico-ureteric reflux was investigated in adult female Wistar rats. In 6 rats, reflux with isotonic saline produced a transient rise in systemic blood pressure followed by a fall, with return to normal within 2 min (mean BP readings: 121-130-93 mmHg). In 6 rats during water diuresis, reflux with distilled water produced similar changes (114-120-79 mmHg). In 6 rats in which the ureters were divided before reflux, no rise in blood pressure occurred although in 2 of these the pressure showed a marked fall. The pattern of blood pressure changes which occurred as a result of reflux was similar to that produced by a rapid i.v. injection of a corresponding volume of saline and it was concluded that the changes accompanying reflux are due to pyelovenous backflow. This was confirmed by producing reflux with 5% lissamine green which appeared in the peripheral capillaries within 4 s of the reflux in 3 rats. Slow dilatation of the pelvis with saline in 9 rats showed that rupture of the pelvic epithelium occurred at a mean pressure of 99 mmHg. PMID:607990

    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.

    Gastroesophageal reflux (GER) is a common, chronic, relapsing symptom. Often people self-diagnose and self-treat it even though health-related quality of life is significantly impaired. In the lack of a valid alternative approach, current treatments focus on suppression of gastric acid secretion by the use of proton pump inhibitors (PPIs), but people with GER have a significantly lower response rate to therapy. We designed a randomized double-blinded controlled clinical study to evaluate the efficacy and the safety of a formulation based on sodium alginate/bicarbonate in combination with extracts obtained from Opuntia ficus-indica and Olea europaea associated with polyphenols (Mucosave®; verum), on GER-related symptoms. Male/female 118 (intention to treat) subjects with moderate GER and having at least 2 to 6 days of GER episodes/week were treated with verum (6 g/day) or placebo for two months. The questionnaires Gastroesophageal Reflux Disease-Health-Related Quality of Life (GERD-HRQoL) and Gastroesophageal Reflux Disease Symptom Assessment Scale (GSAS) were self-administered by participants before the treatment and at the end of the treatment. Verum produced statistically significant reduction of GERD-HRQoL and GSAS scores, −56.5% and −59.1%, respectively, in comparison to placebo. Heartburn and acid regurgitation episodes for week were significantly reduced by verum (p < 0.01). Results indicate that Mucosave formulation provides an effective and well-tolerated treatment for reducing the frequency and intensity of symptoms associated with gastroesophageal reflux.

    AIM To evaluate the agreement of multichannel intraluminal impedance-pH monitoring (MII-pHM) and gastroesophageal reflux scintigraphy (GES) for the diagnosis of gastroesophageal reflux disease. METHODS Seventy-five consecutive patients with suspected gastroesophageal reflux disease (GERD) underwent 24-h combined MII-pHM recording and one hour radionuclide scintigraphy during the course of the MII-pHM study. Catheters with 6 impedance channels and 1 pH sensor were placed transnasally. Impedance and pH data analysis were performed automatically and manually. For impedance monitoring, reflux was defined as a retrograde 50% drop in impedance, starting distally and propagating retrogradely to at least the next two more proximal measuring channels. Reflux index (RI, percentage of the entire record that esophageal pH is < 4.0) greater than 4.2% for pHM and number of refluxes more than 50 for 24 h for MII were accepted as positive test results. At scintigraphy, 240 frames of 15 seconds duration were acquired in the supine position. Gastroesophageal reflux was defined as at least one reflux episode in the esophagus. After scintigraphic evaluation, impedance-pH recordings and scintigraphic images were evaluated together and agreement between tests were evaluated with Cohen’s kappa. RESULTS Sufficient data was obtained from 60 (80%) patients (34 male, 56.7%) with a mean age of 8.7 ± 3.7 years (range: 2.5-17.3 years; median: 8.5 years). Chronic cough, nausea, regurgitation and vomiting were the most frequent symptoms. The mean time for recording of MII-pHM was 22.8 ± 2.4 h (range: 16-30 h; median: 22.7 h). At least one test was positive in 57 (95%) patients. According to diagnostic criteria, GERD was diagnosed in 34 (57.7%), 44 (73.3%), 47 (78.3%) and 51 (85%) patients by means of pHM, MII, GES and MII-pHM, respectively. The observed percentage agreements/κ values for GES and pHM, GES and MII, GES and MII-pHM, and MII and pHM are 48.3%/-0.118; 61.7%/-0.042; 73

    Gastroesophageal reflux and gastroesophageal reflux disease symptoms are common challenges for very low-birth-weight infants (<1500 g). These symptoms frequently result in feeding difficulties and family stress. Management of symptoms across healthcare disciplines may not be based on current evidence, and inconsistency can result in confusion for families and delayed interventions. The feeding relationship between infant and caregivers may be impaired when symptoms are persistent and poorly managed. An algorithm for managing gastroesophageal reflux-like symptoms in very low-birth-weight infants (from hospital discharge to 12 months corrected age) was developed through the formation of a multidisciplinary community of practice and critical appraisal of the literature. A case study demonstrates how the algorithm results in a consistent approach for identifying symptoms, applying appropriate management strategies, and facilitating appropriate timing of medical consultation. Application to managing gastroesophageal reflux symptoms in the neonatal intensive care unit will be briefly addressed.

    Gastroesophageal reflux disease (GERD) is a common disorder that has a well-established connection with obesity. To ameliorate the morbidity associated with obesity, bariatric procedures have become an established pathway to accomplish sustained weight loss. In some procedures, such as with the Roux-en-Y gastric bypass surgery, weight loss is also accompanied by the resolution of GERD symptoms. However, other popular bariatric surgeries, such as the sleeve gastrectomy, have a controversial impact on their effect on reflux. Consequently, increased attention has been given to the development of strategies for the management of de novo or recurrent reflux after bariatric surgery. This article aims to discuss medical and surgical strategies for reflux after bariatric surgery, and their outcomes.

    Of 134 girls with demonstrable ureterovesical reflux, 61 (105 ureters) had the reflux surgically corrected with an overall surgical cure rate of 97 percent. In the remaining 73 children (112 ureters), the reflux was treated conservatively with medical management alone. During the follow-up period no significant differences were demonstrated in the overall incidence of urinary tract infection; two years following corrective operation or medical treatment more than 50 percent of both medically and surgically treated children were still experiencing infections. A pronounced decrease, however, occurred in the incidence of clinical pyelonephritis among the surgically treated group. Following correction of reflux, the incidence of pyelonephritis was similar in both medically and surgically treated cases and was approximately the same as that found in a comparable group of children without reflux. In approximately two-thirds of refluxing renal units in which there was evidence of clubbing and scarring before medical or surgical therapy, deterioration progressed during the follow-up period. In most of these cases infection control was felt to be inadequate with episodes of clinical pyelonephritis occurring during the period of medical management, or, in the surgically treated group, occurring just before corrective operation and the scar appearing within two years after operation. The majority of renal units in which calyceal clubbing and parenchymal scarring was present had the most severe grades of reflux. PMID:4460380

    2010-04-01

    Gastroesophageal reflux is extremely common in Western countries. For selected patients, there is an established role for the surgical treatment of reflux, and possibly an emerging role for endoscopic antireflux procedures. Randomized trials have compared medical versus surgical management, laparoscopic versus open surgery and partial versus total fundoplications. However, the evidence base for endoscopic procedures is limited to some small sham-controlled studies, and cohort studies with short-term follow-up. Laparoscopic fundoplication has been shown to be an effective antireflux operation. It facilitates quicker convalescence and is associated with fewer complications, but has a similar longer term outcome compared with open antireflux surgery. In most randomized trials, antireflux surgery achieves at least as good control of reflux as medical therapy, and these studies support a wider application of surgery for the treatment of moderate-to-severe reflux. Laparoscopic partial fundoplication is an effective surgical procedure with fewer side effects, and it may achieve high rates of patient satisfaction at late follow-up. Many of the early endoscopic antireflux procedures have failed to achieve effective reflux control, and they have been withdrawn from the market. Newer procedures have the potential to fashion a surgical fundoplication. However, at present there is insufficient evidence to establish the safety and efficacy of endoscopic procedures for the treatment of gastroesophageal reflux, and no endoscopic procedure has achieved equivalent reflux control to that achieved by surgical fundoplication.

    We evaluated the predictors of renal scar in children with urinary tract infections (UTIs) having primary vesicoureteral reflux (VUR). Data of patients who were examined by dimercaptosuccinic acid (DMSA) scintigraphy between 1995 and 2005 were evaluated retrospectively. Gender, age, reflux grade, presence/development of scarring, breakthrough UTIs, and resolution of reflux, were recorded. The relation of gender, age and VUR grade to preformed scarring and the relation of gender, age, VUR grade, presence of preformed scarring, number of breakthrough UTIs and reflux resolution to new scarring were assessed. There were 138 patients [male/female (M/F) 53/85]. Multivariate analysis showed that male gender [odds ratio (OR) 2.5], age > or = 27 months in girls (OR 4.2) and grades IV-V reflux (OR 12.4) were independent indicators of renal scarring. On the other hand, only the presence of previous renal scarring was found to be an independent indicator for the development of new renal scar (OR 13.4). In conclusion, while the most predictive variables for the presence of renal scarring among children presenting with a UTI were male gender, age > or = 27 months in girls, and grades IV-V reflux, the best predictor of new scar formation was presence of previous renal scarring.

    Although the outcome of newborns with surgical congenital diseases (e.g., diaphragmatic hernia; esophageal atresia; omphalocele; gastroschisis) has improved rapidly with recent advances in perinatal intensive care and surgery, infant survivors often require intensive treatment after birth, have prolonged hospitalizations, and, after discharge, may have long-term sequelae including gastro-intestinal comorbidities, above all, gastroesophageal reflux (GER). This condition involves the involuntary retrograde passage of gastric contents into the esophagus, with or without regurgitation or vomiting. It is a well-recognized condition, typical of infants, with an incidence of 85%, which usually resolves after physiological maturation of the lower esophageal sphincter and lengthening of the intra-abdominal esophagus, in the first few months after birth. Although the exact cause of abnormal esophageal function in congenital defects is not clearly understood, it has been hypothesized that common (increased intra-abdominal pressure after closure of the abdominal defect) and/or specific (e.g., motility disturbance of the upper gastrointestinal tract, damage of esophageal peristaltic pump) pathological mechanisms may play a role in the etiology of GER in patients with birth defects. Improvement of knowledge could positively impact the long-term prognosis of patients with surgical congenital diseases. The present manuscript provides a literature review focused on pathological and clinical characteristics of GER in patients who have undergone surgical treatment for congenital abdominal malformations.

    Among the fatty acids, it is the omega-3 polyunsaturated fatty acids (PUFA) which possess the most potent immunomodulatory activities, and among the omega-3 PUFA, those from fish oil-eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)--are more biologically potent than alpha-linolenic acid (ALA). Some of the effects of omega-3 PUFA are brought about by modulation of the amount and types of eicosanoids made, and other effects are elicited by eicosanoid-independent mechanisms, including actions upon intracellular signaling pathways, transcription factor activity and gene expression. Animal experiments and clinical intervention studies indicate that omega-3 fatty acids have anti-inflammatory properties and, therefore, might be useful in the management of inflammatory and autoimmune diseases. Coronary heart disease, major depression, aging and cancer are characterized by an increased level of interleukin 1 (IL-1), a proinflammatory cytokine. Similarly, arthritis, Crohn's disease, ulcerative colitis and lupus erythematosis are autoimmune diseases characterized by a high level of IL-1 and the proinflammatory leukotriene LTB(4) produced by omega-6 fatty acids. There have been a number of clinical trials assessing the benefits of dietary supplementation with fish oils in several inflammatory and autoimmune diseases in humans, including rheumatoid arthritis, Crohn's disease, ulcerative colitis, psoriasis, lupus erythematosus, multiple sclerosis and migraine headaches. Many of the placebo-controlled trials of fish oil in chronic inflammatory diseases reveal significant benefit, including decreased disease activity and a lowered use of anti-inflammatory drugs.

    Background/Aims Neurologically impaired patients frequently suffer from gastrointestinal tract problems, such as gastroesophageal reflux disease (GERD). In this study, we aimed to define the risk factors for GERD in neurologically impaired children. Methods From May 2006 to March 2014, 101 neurologically impaired children who received 24-hour esophageal pH monitoring at Severance Children’s Hospital were enrolled in the study. The esophageal pH finding and the clinical characteristics of the patients were analyzed. Results The reflux index was higher in patients with abnormal electroencephalography (EEG) results than in those with normal EEG results (p=0.027). Mitochondrial disease was associated with a higher reflux index than were epileptic disorders or cerebral palsy (p=0.009). Patient gender, feeding method, scoliosis, tracheostomy, and baclofen use did not lead to statistical differences in reflux index. Age of onset of neurological impairment was inversely correlated with DeMeester score and reflux index. Age at the time of examination, the duration of the disease, and the number of antiepileptic drugs were not correlated with GER severity. Conclusions Early-onset neurological impairment, abnormal EEG results, and mitochondrial disease are risk factors for severe GERD. PMID:27840365

    Proteins are playing a vital role in maintaining the cellular integrity and function, as well as for brain cells. Protein intake and supplementation of individual amino acids can affect the brain functioning and mental health, and many of the neurotransmitters in the brain are made from amino acids. The amino acid supplementation has been found to reduce symptoms, as they are converted into neurotransmitters which in turn extenuate the mental disorders. The biosynthesis of amino acids in the brain is regulated by the concentration of amino acids in plasma. The brain diseases such as depression, bipolar disorder, schizophrenia, obsessive-compulsive disorder (OCD), and Alzheimer's (AD), Parkinson's (PD), and Huntington's diseases (HD) are the most common mental disorders that are currently widespread in numerous countries. The intricate biochemical and molecular machinery contributing to the neurological disorders is still unknown, and in this chapter, we revealed the involvement of dietary amino acids on neurological diseases.

    Human beings evolved consuming a diet that contained about equal amounts of n-3 and n-6 essential fatty acids. Over the past 100-150 y there has been an enormous increase in the consumption of n-6 fatty acids due to the increased intake of vegetable oils from corn, sunflower seeds, safflower seeds, cottonseed, and soybeans. Today, in Western diets, the ratio of n-6 to n-3 fatty acids ranges from approximately 20-30:1 instead of the traditional range of 1-2:1. Studies indicate that a high intake of n-6 fatty acids shifts the physiologic state to one that is prothrombotic and proaggregatory, characterized by increases in blood viscosity, vasospasm, and vasoconstriction and decreases in bleeding time. n-3 Fatty acids, however, have antiinflammatory, antithrombotic, antiarrhythmic, hypolipidemic, and vasodilatory properties. These beneficial effects of n-3 fatty acids have been shown in the secondary prevention of coronary heart disease, hypertension, type 2 diabetes, and, in some patients with renal disease, rheumatoid arthritis, ulcerative colitis, Crohn disease, and chronic obstructive pulmonary disease. Most of the studies were carried out with fish oils [eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)]. However, alpha-linolenic acid, found in green leafy vegetables, flaxseed, rapeseed, and walnuts, desaturates and elongates in the human body to EPA and DHA and by itself may have beneficial effects in health and in the control of chronic diseases.

    Cervical venous reflux, shown by dynamic brain scintigraphy, was investigated through three avenues of approach: (A) by reviewing 371 randomly chosen routine dynamic intracerebral bloodflow studies to estimate its incidence; (B) by correlative positive-contrast superior venacavography in patients with characteristic cervical venous reflux; and (C) by performing dynamic brain scintigraphy while utilizing various positional and physiologic maneuvers to attempt to produce cervical venous reflux in patients who did not exhibit this phenomenon on earlier examination. Although any obstruction of the superior vena cava or a properly timed Valsalva maneuver in selected patients can produce the scintigraphic picture of cervical venous reflux, in most cases it is a normal phenomenon due to incompetent or absent cervical venous valves.

    Gastroesophageal reflux disease (GERD) and functional dyspepsia (FD) are common problems in the pediatric population, with up to 7% of school-age children and up to 8% of adolescents suffering from epigastric pain, heartburn, and regurgitation. Reflux is defined as the passage of stomach contents into the esophagus, while GERD refers to reflux symptoms that are associated with symptoms or complications—such as pain, asthma, aspiration pneumonia, or chronic cough. FD, as defined by the Rome III classification, is a persistent upper abdominal pain or discomfort, not related to bowel movements, and without any organic cause, that is present for at least two months prior to diagnosis. Endoscopic examination is typically negative in FD, whereas patients with GERD may have evidence of esophagitis or gastritis either grossly or microscopically. Up to 70% of children with dyspepsia exhibit delayed gastric emptying. Treatment of GERD and FD requires an integrative approach that may include pharmacologic therapy, treating concurrent constipation, botanicals, mind body techniques, improving sleep hygiene, increasing physical activity, and traditional Chinese medicine and acupuncture.

    Bile acids are the end products of cholesterol catabolism. Hepatic bile acid synthesis accounts for a major fraction of daily cholesterol turnover in humans. Biliary secretion of bile acids generates bile flow and facilitates hepatobiliary secretion of lipids, lipophilic metabolites, and xenobiotics. In the intestine, bile acids are essential for the absorption, transport, and metabolism of dietary fats and lipid-soluble vitamins. Extensive research in the last 2 decades has unveiled new functions of bile acids as signaling molecules and metabolic integrators. The bile acid-activated nuclear receptors farnesoid X receptor, pregnane X receptor, constitutive androstane receptor, vitamin D receptor, and G protein-coupled bile acid receptor play critical roles in the regulation of lipid, glucose, and energy metabolism, inflammation, and drug metabolism and detoxification. Bile acid synthesis exhibits a strong diurnal rhythm, which is entrained by fasting and refeeding as well as nutrient status and plays an important role for maintaining metabolic homeostasis. Recent research revealed an interaction of liver bile acids and gut microbiota in the regulation of liver metabolism. Circadian disturbance and altered gut microbiota contribute to the pathogenesis of liver diseases, inflammatory bowel diseases, nonalcoholic fatty liver disease, diabetes, and obesity. Bile acids and their derivatives are potential therapeutic agents for treating metabolic diseases of the liver.

    Vesicoureteric reflux is now considered to be due essentially to congenital malformation of the vesicoureteric junction. It is also considered to be a major cause of renal failure in early adult life. The condition is associated with recurrent urinary tract infection and in some instances with renal scarring. When reflux is detected clinically, in the investigation of patients with recurrent urinary tract infection, renal scarring is often already present. The reflux tends to disappear in later childhood. A family study has been made based on 186 index patients with established primary reflux, with special attention to a history of genitourinary symptoms in the sibs and parents of these patients. There were 39 sibs under the age of 4 years. For these the parents were offered investigation by micturating cystogram. The parents of 20 accepted. Reflux was shown in 3, and in 2 of these there was already renal scarring. The proportion of all infants and young children who have reflux is not accurately known, but the few published surveys of screening of normal infants and young children by micturating cystogram suggest that the prevalence is of the order of 1%. The prevalence in sibs is, then, about 10 times higher. There was a main group of 214 sibs over the age of 4 years. For these the parents were offered investigation by intravenous pyelogram only for those sibs who had a history of recurrent urinary tract infection. If renal scarring was found then a micturating cystogram was done. Of 110 sisters, 12 were `symptomatic', renal scarring was found in 5 of these (1 was on haemodialysis), and reflux was still present in 3. Of 104 brothers 7 were `symptomatic', renal scarring was found in 2 and reflux was present in both. For comparison, the published reports of several surveys of schoolgirls indicate that about 2 in 100 have recurrent urinary tract infection, and in about a quarter of these (0·5%) reflux was present and in about one-eighth (0·25%) renal scarring was

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

    Technological advances in the last few decennia allow the monitoring of many physiological observables in a continuous way, which in physics is called a "time series". The best studied physiological time series is that of the heart rhythm, which can be derived from an electrocardiogram (ECG). Studies have shown that a healthy heart is characterized by a complex time series and high heart rate variability (HRV). In adverse conditions, the cardiac time series degenerates towards randomness (as seen in, e.g., fibrillation) or rigidity (as seen in, e.g., ageing), both corresponding to a loss of HRV as described by, e.g., Golberger et. al [1]. Cardiac and digestive rhythms are regulated by the autonomous nervous system (ANS), that consists of two antagonistic branches, the orthosympathetic branch (ONS) that accelerates the cardiac rhythm but decelerates the digestive system, and the parasympathetic brand (PNS) that works in the opposite way. Because of this reason, one might expect that the statistics of gastro-esophageal time series, as described by Gardner et. al. [2,3], reflects the health state of the digestive system in a similar way as HRV in the cardiac case, described by Minocha et. al. In the present project, we apply statistical methods derived from HRV analysis to time series of esophageal acidity (24h pHmetry). The study is realized on data from a large patient population from the Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán. Our focus is on patients with functional disease (symptoms but no anatomical damage). We find that traditional statistical approaches (e.g. Fourier spectral analysis) are unable to distinguish between different degenerations of the digestive system, such as gastric esophageal reflux disease (GERD) or functional gastrointestinal disorder (FGID).

    One challenge in studying chronic infectious and inflammatory disorders is understanding how host pattern recognition receptors (PRRs), specifically toll-like receptors (TLRs), sense and respond to pathogen- or damage-associated molecular patterns, their communication with each other and different components of the immune system, and their role in propagating inflammatory stages of disease. The discovery of innate immune activation through nucleic acid recognition by intracellular PRRs such as endosomal TLRs (TLR3, TLR7, TLR8, and TLR9) and cytoplasmic proteins (absent in melanoma 2 and DNA-dependent activator of interferon regulatory factor) opened a new paradigm: Nucleic acid sensing is now implicated in multiple immune and inflammatory conditions (e.g., atherosclerosis, cancer), viral (e.g., human papillomavirus, herpes virus) and bacterial (e.g., Helicobacter pylori, pneumonia) diseases, and autoimmune disorders (e.g., systemic lupus erythematosus, rheumatoid arthritis). Clinical investigations reveal the overexpression of specific nucleic acid sensors in diseased tissues. In vivo animal models show enhanced disease progression associated with receptor activation. The involvement of nucleic acid sensors in various systemic conditions is further supported by studies reporting receptor knockout mice being either protected from or prone to disease. TLR9-mediated inflammation is also implicated in periodontal diseases. Considering that persistent inflammation in the oral cavity is associated with systemic diseases and that oral microbial DNA is isolated at distal sites, nucleic acid sensing may potentially be a link between oral and systemic diseases. In this review, we discuss recent advances in how intracellular PRRs respond to microbial nucleic acids and emerging views on the role of nucleic acid sensors in various systemic diseases. We also highlight new information on the role of intracellular PRRs in the pathogenesis of oral diseases including periodontitis

    Helicobacter pylori is responsible for most peptic ulcers, plays a role in functional dyspepsia and is thought by some to influence the course of gastroesophageal reflux disease. This article addresses recent studies that have been published in connection with these diseases. H. pylori-associated peptic ulcer is declining in prevalence but the incidence of perforation and bleeding remains high especially in the elderly. All H. pylori associated peptic ulcers should be treated by eradication of the infection. Dyspepsia is a common disorder that affects up to 25% of the population. About 8% of cases that are infected with H. pylori will respond to treatment of the infection. The association between H. pylori and gastroesophageal reflux disease continues to be debated, a number of studies have shown that there is a negative association between H. pylori infection and Gastroesophageal reflux disease but treatment of H. pylori has not been shown to induce reflux or to affect the response to medication. Gastric atrophy is known to extend when acid suppression is used in infected patients implying that H. pylori treatment should be used in infected patients who are to undergo long-term Proton Pump Inhibitor therapy.

    Objective The aim of this study was to evaluate the Laparoscopic Sleeve Gastrectomy (LSG) with simultaneous crural repair in treatment of morbid obesity associated with gastroesophageal reflux disease. Methods This prospective observational study was carried out from September 2012 to July 2016 in Al-Azhar University Hospital (Egypt). The study was conducted on 53 patients, 14 males (26.4%) and 39 females (73.6%) with the mean age 36.2 years (range 18–52 years), presenting with morbid obesity and reflux disease either symptomatic patients or asymptomatic (Endoscopic & Manometric), their mean Body Mass Index (BMI) was 50.1 kg/m2 (range 40–62 kg/m2), who underwent LSG and antireflux procedure (crural repair). Results Excess weight Loss (EWL); the mean EWL at 6 months postoperatively was 46.3%, at 12 months was 54%, and at 18 months was 61%. Also, we found that, preoperative co-morbidities are resolved by 53% and improved by 23%. Reflux symptoms were absent in 30 patients (56 %), improved in 14 patients (26.4 %), but persistent in 7 patients (13.2 %). Conclusion Laparoscopic crural closure, during LSG, represents a valuable option for the treatment of morbid obesity and gastroesophageal reflux, and can result in favorable outcomes in terms of weight loss and gastroesophageal reflux disease (GERD) symptoms control.

    After a cardiac source has been excluded, the most likely cause of NCCP is GERD. Clinical history often cannot make the diagnosis of GERD-related NCCP. The PPI test is a simple, highly sensitive, and cost-effective tool that should be the first diagnostic test used in evaluating these patients. Patients with GERD-related NCCP require long-term therapy with a PPI,commonly double the standard dose. The introduction of the wireless pH system and the multi-channel intraluminal impedance will help us to further understand the role of GERD in NCCP. Treatment of NCCP has dramatically improved since the introduction of the PPI class of drugs.However, better therapeutic modalities should be sought out to further improve our current treatment of GERD-related NCCP.

    2016-08-02

    Nonalcoholic fatty liver disease (NAFLD) is characterized by fat deposition in hepatocytes, and a strong association with nutritional factors. Dietary fatty acids are classified according to their biochemical properties, which confer their bioactive roles. Monounsaturated fatty acids have a dual role in various human and murine models. In contrast, polyunsaturated fatty acids exhibit antiobesity, anti steatosic and anti-inflammatory effects. The combination of these forms of fatty acids-according to dietary type, daily intake and the proportion of n-6 to n-3 fats-can compromise hepatic lipid metabolism. A chemosensory rather than a nutritional role makes bioactive fatty acids possible biomarkers for NAFLD. Bioactive fatty acids provide health benefits through modification of fatty acid composition and modulating the activity of liver cells during liver fibrosis. More and better evidence is necessary to elucidate the role of bioactive fatty acids in nutritional and clinical treatment strategies for patients with NAFLD.

    Fasting and postprandial intragastric bile acid concentrations have been estimated and compared in patients with complications of Barrett's oesophagus, patients with Barrett's oesophagus without complications, patients with oesophagitis and a group of normal subjects who acted as controls. There was no significant difference in fasting intragastric bile acid concentrations between the groups. Postprandial bile acid concentrations were significantly greater in the patients with complications of Barrett's than in the remaining groups at 60, 90 and 120 min. Significant concentrations of bile acids were seen in gastric juice of unaltered pH and may be undetected on intra-oesophageal pH monitoring. Duodenogastric reflux may be implicated in the pathogenesis of complications of Barrett's oesophagus.

    Huntington disease is an autosomal dominant neurodegenerative disorder characterized by behavioral abnormalities, cognitive decline, and involuntary movements that lead to a progressive decline in functional capacity, independence, and ultimately death. The pathophysiology of Huntington disease is linked to an expanded trinucleotide repeat of cytosine-adenine-guanine (CAG) in the IT-15 gene on chromosome 4. There is no disease-modifying treatment for Huntington disease, and novel pathophysiological insights and therapeutic strategies are needed. Lipids are vital to the health of the central nervous system, and research in animals and humans has revealed that cholesterol metabolism is disrupted in Huntington disease. This lipid dysregulation has been linked to specific actions of the mutant huntingtin on sterol regulatory element binding proteins. This results in lower cholesterol levels in affected areas of the brain with evidence that this depletion is pathologic. Huntington disease is also associated with a pattern of insulin resistance characterized by a catabolic state resulting in weight loss and a lower body mass index than individuals without Huntington disease. Insulin resistance appears to act as a metabolic stressor attending disease progression. The fish-derived omega-3 fatty acids, eicosapentaenoic acid and docosahexaenoic acid, have been examined in clinical trials of Huntington disease patients. Drugs that combat the dysregulated lipid milieu in Huntington disease may help treat this perplexing and catastrophic genetic disease. PMID:20802793

    Advances in basic retinal anatomy, genetics, biochemical pathways and neurochemistry have not only provided a better understanding of retinal function but have also allowed us to link basic science to retinal disease. The link with disease allowed measures to be developed that now provide an opportunity to intervene and slow down or even restore sight in previously 'untreatable' retinal diseases. One of the critical advances has been the understanding of the retinal amino acid neurotransmitters, related amino acids, their metabolites and functional receptors. This review provides an overview of amino acid localisation in the retina and examples of how retinal anatomy and amino acid neurochemistry directly links to understanding retinal disease. Also, the implications of retinal remodelling involving amino acid (glutamate) receptors are outlined in this review and insights are presented on how understanding of detrimental and beneficial retinal remodelling will provide better outcomes for patients using strategies for the preservation or restoration of vision.

    Background/Aims Respiratory symptoms are often associated with gastroesophageal reflux disease (GERD). Although the role of multichannel intraluminal impedance–pH (MII-pH) monitoring in GERD is clear, little is known regarding the characteristics of patients with respiratory symptoms based on MII-pH monitoring and anti-reflux therapy. We evaluated a cohort of GERD patients to identify the MII-pH parameters of GERD-related respiratory symptoms and to assess the anti-reflux therapy outcomes. Methods We undertook a prospective study of patients who were referred for GERD evaluation from January 2011 to January 2012. One hundred ninety-five patients underwent MII-pH monitoring and esophageal manometry, and one hundred sixty-five patients underwent invasive anti-reflux therapy that included laparoscopic Toupet fundoplication (LTF) and the Stretta procedure. The patient characteristics and MII-pH parameters were analyzed, and the symptom scores were assessed at baseline and at 1- and 3-year follow-up evaluations. Results Of the 195 patients, 96 (49.2%) exhibited respiratory symptoms and significantly more reflux episodes (70.7±29.3) than patients without respiratory symptoms (64.7±24.4, p = 0.044) based on the MII-pH monitoring results. Moreover, the group of patients with respiratory symptoms exhibited more proximal reflux episodes (35.2±21.3) than the non-respiratory symptomatic group (28.3±17.9, p = 0.013). One hundred twenty-five patients following the Stretta procedure (n = 60, 31 with respiratory symptoms) or LTF (n = 65, 35 with respiratory symptoms) completed the designated 3-year follow-up period and were included in the final analysis. The symptom scores after anti-reflux therapy all decreased relative to the corresponding baseline values (p<0.05), and there were no significant differences in the control of respiration between the Stretta procedure and LTF (p>0.05). However, LTF significantly reduced the recurrence (re-operation) rate compared with the

    This study determines the relationship among esophageal dysmotility, esophageal acid exposure, and esophageal mucosal injury in patients with gastroesophageal reflux disease (GERD). A total of 827 patients with GERD (confirmed by ambulatory pH monitoring) were divided into three groups based on the degree of mucosal injury: group A, no esophagitis, 493 patients; group B, esophagitis grades I to III, 273 patients; and group C, Barrett's esophagus, 61 patients. As mucosal damage progressed from no esophagitis to Barrett's esophagus, there was a significant decrease in lower esophageal sphincter pressure and amplitude of peristalsis in the distal esophagus, with a subsequent increase in the number of reflux episodes in 24 hours, the number of reflux episodes longer than 5 minutes, and the reflux score. These data suggest that in patients with GERD, worsening of esophageal mucosal injury may determine progressive deterioration of esophageal motor function with impairment of acid clearance and increase of esophageal acid exposure. These findings suggest that Barrett's esophagus is an end-stage form of gastroesophageal reflux, and that if surgical therapy is performed early in the course of the disease, this cascade of events might be blocked.

    Uric acid may be a risk factor for atherosclerotic cardiovascular disease, although the data conflict and the mechanism by which it may cause cardiovascular disease is uncertain. This study was performed to test the hypothesis that uric acid, an anion at physiologic pH, can cause erythrocyte aggregation, which itself is associated with cardiovascular disease. Normal erythrocytes and erythrocytes with a positive direct antiglobulin test for surface IgG were incubated for 15 minutes in 14.8 mg/dL uric acid. Erythrocytes without added uric acid were used as controls. Erythrocytes were then examined microscopically for aggregation. Aggregates of up to 30 erythrocytes were noted when normal erythrocytes were incubated in uric acid. Larger aggregates were noted when erythrocytes with surface IgG were incubated in uric acid. Aggregation was negligible in controls. These data show that uric acid causes erythrocyte aggregation. The most likely mechanism is decreased erythrocyte zeta potential. Erythrocyte aggregates will increase blood viscosity at low shear rates and increase the risk of atherothrombosis. In this manner, hyperuricemia and decreased zeta potential may be risk factors for atherosclerotic cardiovascular disease.

    Purpose This study was conducted to determine the predictive value of clinical, laboratory, and imaging variables for the diagnosis of vesicoureteral reflux in children with their first febrile urinary tract infection. Materials and Methods One hundred fifty-three children with their first febrile urinary tract infection were divided into two groups according to the results of voiding cystourethrography: 60 children with vesicoureteral reflux and 93 children without. The sensitivity, specificity, positive and negative predictive value, likelihood ratio (positive and negative), and accuracy of the clinical, laboratory, and imaging variables for the diagnosis of vesicoureteral reflux were determined. Results Of the 153 children with febrile urinary tract infection, 60 patients (39.2%) had vesicoureteral reflux. There were significant differences between the two groups regarding fever>38℃, suprapubic pain, C-reactive protein quantitative level, number of red blood cells in the urine, and results of renal ultrasound and dimercaptosuccinic acid renal scanning (p<0.05). There were significant positive correlations between fever>38.2℃ and dimercaptosuccinic acid renal scanning and vesicoureteral reflux. Also, there were significant positive correlations between the erythrocyte sedimentation rate, positive urinary nitrite test, hyaline cast, and renal ultrasound and high-grade vesicoureteral reflux. Conclusions This study revealed fever>38.2℃ and dimercaptosuccinic acid renal scanning as the best predictive markers for vesicoureteral reflux in children with their first febrile urinary tract infection. In addition, erythrocyte sedimentation rate, positive urinary nitrite test, hyaline cast, and renal ultrasound are the best predictive markers for high-grade vesicoureteral reflux. PMID:25132949

    Nitric oxide (NO) produced by inducible nitric oxide synthase (iNOS) has been implicated in both DNA damage induction and aberrant cell signalling in various tissue and cell backgrounds. We investigated here the role of iNOS and NO in DNA damage induction and nuclear factor-kappa B (NF-κB) signalling in esophageal cells in vitro. As esophageal adenocarcinoma develops in a background of Barrett's esophagus secondary to reflux disease, it is possible that inflammatory mediators like NO may be important in esophageal cancer development. We show that reflux components like stomach acid and bile acids [deoxycholic acid (DCA)] can induce iNOS gene and protein expression and produce NO generation in esophageal cells, using real-time PCR, western blotting and NO sensitive fluorescent probes, respectively. This up-regulation of iNOS expression was not dependent on NF-κB activity. DCA-induced DNA damage was independent of NF-κB and only partially dependent on iNOS and NO, as measured by the micronucleus assay. These same reflux constituents also activated the oncogenic transcription factor NF-κB, as measured by transcription factor enzyme-linked immunosorbent assay and gene expression studies with NF-κB linked genes (e.g. interleukin-8). Importantly, we show here for the first time that basal levels of NF-κB activity (and possibly acid and DCA-induced NF-κB) are dependent on iNOS/NO and this may lead to a positive feedback loop whereby induced iNOS is upstream of NF-κB, hence prolonging and potentially amplifying this signalling, presumably through NO activation of NF-κB. Furthermore, we confirm increased protein levels of iNOS in esophageal adenocarcinoma and, therefore, in neoplastic development in the esophagus.

    We studied the role of urethrovesical reflux in the onset and maintenance of chronic inflammation in the urinary bladder in patients suffering from chronic cystitis combined with pseudopolyposis of the neck of the bladder and proximal part of the urethra. We modelled a simplified version of an urination fragment of a special computer graphic station. The original computer model theoretically proves the existance of urethrovesical reflux caused by pseudopolyposis in the zone of the urinary bladder cervix and/or proximal urethra. The data were confirmed by radionuclide investigation. Our studies proved the presence of urethrovesical reflux in patients with pseudopolyposis of the bladder cervix provoking retrograde infection of the lower urinary tract. We think it necessary to combine conventional conservative treatment of cystitis with endourethral surgical interventions aimed at reestablishment of normal urination.

    In order to study the effect of the new M1-selective antimuscarinic compound telenzepine on physiological esophageal acid exposure, ten healthy volunteers underwent a 24-hour esophageal pH-monitoring during a one week treatment with either tablets containing telenzepine 3 mg nightly or placebo in a double-blind cross-over trial. Side-effects were recorded, and stimulated salivary output was assessed. Using a cut-off pH less than 4, under telenzepine a significant reduction of reflux time and of maximum reflux duration was observed in supine position. Using a cut-off pH less than 2, reflux time was reduced during and after meals, number of refluxes was decreased during meals, and esophageal clearance was improved with telenzepine in supine position. Telenzepine reduced salivary output significantly on day 4 and on day 7. From the results it can be concluded that the drug is not contraindicated in peptic ulcer patients with heartburn. As telenzepine reduces gastroesophageal reflux time during and after meals and in supine position it may be tried as adjuvant treatment in esophageal reflux disease.

  9. Amino Acid Catabolism in Alzheimer's Disease Brain: Friend or Foe?

    PubMed Central

    2017-01-01

    There is a dire need to discover new targets for Alzheimer's disease (AD) drug development. Decreased neuronal glucose metabolism that occurs in AD brain could play a central role in disease progression. Little is known about the compensatory neuronal changes that occur to attempt to maintain energy homeostasis. In this review using the PubMed literature database, we summarize evidence that amino acid oxidation can temporarily compensate for the decreased glucose metabolism, but eventually altered amino acid and amino acid catabolite levels likely lead to toxicities contributing to AD progression. Because amino acids are involved in so many cellular metabolic and signaling pathways, the effects of altered amino acid metabolism in AD brain are far-reaching. Possible pathological results from changes in the levels of several important amino acids are discussed. Urea cycle function may be induced in endothelial cells of AD patient brains, possibly to remove excess ammonia produced from increased amino acid catabolism. Studying AD from a metabolic perspective provides new insights into AD pathogenesis and may lead to the discovery of dietary metabolite supplements that can partially compensate for alterations of enzymatic function to delay AD or alleviate some of the suffering caused by the disease.

    Severe symptoms of heartburn and retrosternal pain consistent with gastro-esophageal reflux (GER) developed in a patient following placement of a conventional self-expanding 16-24-mm-diameter x 12-cm-long esophageal stent across the gastroesophageal junction to treat an obstructing esophageal carcinoma. A second 18-mm-diameter x 10-cm-long esophageal stent with anti-reflux valve was deployed coaxially and reduced symptomatic GER immediately. Improvement was sustained at 4-month follow-up. An anti-reflux stent can be successfully used to treat significant symptomatic GER after conventional stenting.

    Bile acids are well known for their effects on cholesterol homeostasis and lipid digestion. Since the discovery of bile acid receptors, of which there are farnesoid X receptor (FXR), a nuclear receptor, and the plasma membrane G-protein receptor, as well as Takeda G-protein coupled receptor clone 5, further roles have been elucidated for bile acids including glucose and lipid metabolism as well as inflammation. Additionally, treatment with bile acid receptor agonists has shown a decrease in the amount of atherosclerosis plaque formation and decreased portal vascular resistance and portal hypotension in animal models. Furthermore, rodent models have demonstrated antifibrotic activity using bile acid receptor agonists. Early human data using a FXR agonist, obeticholic acid, have shown promising results with improvement of histological activity and even a reduction of fibrosis. Human studies are ongoing and will provide further information on bile acid receptor agonist therapies. Thus, bile acids and their derivatives have the potential for management of liver diseases and potentially other disease states including diabetes and the metabolic syndrome. PMID:26320013

    Gastroesophageal reflux (GER), asthma-type cough and upper airway disease are the most common causes of chronic cough syndrome. We present a case in which impedance–pH monitoring indicated severe mixed acid–nonacid esophageal reflux reaching the upper third of the esophagus in 75% of nonacid events. GER and the associated aspiration episodes were shown to be the cause of severe asthma attacks and migratory pulmonary infiltrates. GER was caused by a sleeve gastrectomy, which seriously disabled the mechanisms preventing reflux from reaching the airways. Respiratory symptoms improved notably after abdominal surgery to correct the GER, suggesting a close causal relationship between GER and all the symptoms, including asthma. However, this issue remains unresolved in the literature. PMID:25473547

    Glycyrrhizic acid (GA) is a triterpene glycoside found in the roots of licorice plants (Glycyrrhiza glabra). GA is the most important active ingredient in the licorice root, and possesses a wide range of pharmacological and biological activities. GA coupled with glycyrrhetinic acid and 18-beta-glycyrrhetic acid was developed in China or Japan as an anti-inflammatory, antiviral, and antiallergic drug for liver disease. This review summarizes the current biological activities of GA and its medical applications in liver diseases. The pharmacological actions of GA include inhibition of hepatic apoptosis and necrosis; anti-inflammatory and immune regulatory actions; antiviral effects; and antitumor effects. This paper will be a useful reference for physicians and biologists researching GA and will open the door to novel agents in drug discovery and development from Chinese herbs. With additional research, GA may be more widely used in the treatment of liver diseases or other conditions. PMID:24963489

    Hyperuricemia is defined as serum uric acid level of more than 7 mg/dL and blood levels of uric acid are causally associated with gout, as implicated by evidence from randomized clinical trials using urate lowering therapies. Uric acid as a cardiovascular risk factor often accompanies metabolic syndrome, hypertension, diabetes, dyslipidemia, chronic renal disease, and obesity. Despite the association of hyperuricemia with cardiovascular risk factors, it has remained controversial as to whether uric acid is an independent predictor of cardiovascular disease. To settle this issue, and in the absence of large randomized controlled trials, Mendelian randomization analysis in which the exposure is defined based on the presence or absence of a specific allele that influences a risk factor of interest have tried to shed light on this.

    Why do neurons sense extracellular acid? In large part, this question has driven increasing investigation on acid-sensing ion channels (ASICs) in the CNS and the peripheral nervous system for the past two decades. Significant progress has been made in understanding the structure and function of ASICs at the molecular level. Studies aimed at clarifying their physiological importance have suggested roles for ASICs in pain, neurological and psychiatric disease. This Review highlights recent findings linking these channels to physiology and disease. In addition, it discusses some of the implications for therapy and points out questions that remain unanswered.

    Nucleic acid-containing debris released from dead and dying cells can be recognized as damage-associated molecular patterns (DAMPs) or pattern-associated molecular patterns (PAMPs) by the innate immune system. Inappropriate activation of the innate immune response can engender pathological inflammation and autoimmune disease. To combat such diseases, major efforts have been made to therapeutically target the pattern recognition receptors (PRRs) such as the Toll-like receptors (TLRs) that recognize such DAMPs and PAMPs, or the downstream effector molecules they engender, to limit inflammation. Unfortunately, such strategies can limit the ability of the immune system to combat infection. Previously, we demonstrated that nucleic acid-binding polymers can act as molecular scavengers and limit the ability of artificial nucleic acid ligands to activate PRRs. Herein, we demonstrate that nucleic acid scavengers (NASs) can limit pathological inflammation and nucleic acid-associated autoimmunity in lupus-prone mice. Moreover, we observe that such NASs do not limit an animal’s ability to combat viral infection, but rather their administration improves survival when animals are challenged with lethal doses of influenza. These results indicate that molecules that scavenge extracellular nucleic acid debris represent potentially safer agents to control pathological inflammation associated with a wide range of autoimmune and infectious diseases.

    Vocal cord dysfunction (VCD), is characterized by a paradoxical adduction of the vocal cords during inspiration, and occurs predominantly in young women. Common symptoms are cough, wheezing, episodic dyspnea, and inspiratory stridor. The true incidence and course of the disease are unknown, and it is usually self limited. It can coexist with, or mimic refractory asthma. Psychological disorders were thought to be the principal cause, subsequently multiple organic diseases have also been reported, like gastroesophageal reflux disease (GERD). Diagnosis is made by clinical suspicion and direct observation. The Gold standard for diagnosis is laryngoscopy with visualization of the paradoxical motion of the vocal cords when the patient is symptomatic. Speech therapy and psychotherapy have been used extensively without any prospective study. We report two cases of VCD associated with GERD, both with excellent respond to treatment.

    The prevalence of gastroesophageal reflux disease (GERD) symptoms in pregnancy is very high, up to 80%, with a maximum peak during the third trimester. Together with lifestyle modifications, antacids and antisecretive agents, such as proton pump inhibitors (PPIs) and histamine H2 receptor antagonists (H2RAs), are commonly prescribed in non-pregnant, adult population. In certain Countries these drugs are not allowed in or are allowed only during the late stages of pregnancy. Alginate-based formulations have been used for the symptomatic treatment of heartburn for decades, as they usually contain sodium or potassium bicarbonate. In the presence of gastric acid, a foamy raft is created above the gastric contents. The alginate raft moves into the esophagus in place or ahead of acidic gastric contents during reflux episodes physically preventing reflux of gastric contents into the esophagus. Alginate-based formulations are allowed with no restrictions also in pregnancy: their safety profile make them a very valid option taking into account the risk/benefit ratio for both parturient and unborn baby. This systematic review paper aims to explore the use of medications for treating GERD in pregnancy, including alginate raft-forming-agents, highlighting the benefits for both the mother and the fetus. Electronic search in databases was conducted on databases such as Medline, PubMed, Ovid retrieving data concerning the reflux treatments in pregnancy, with a special focus on alginate raft forming antireflux agents. From the literature on alginate use in pregnancy, no particular risks have been shown to date for both parturient and unborn baby when alginate had been administered during all the pregnancy trimesters. The physical mode of action ensures the maximum esophageal protection by the neutral foam floating in the stomach, maintaining physiological pH values at stomach level, without interfering with the digestive processes. The symptoms' healing has been markedly improved

    Degenerative diseases of the CNS, such as stiff-person syndrome (SPS), progressive cerebellar ataxia, and Rasmussen encephalitis, have been characterized by the presence of autoantibodies. Recent findings in individuals with Batten disease and in animal models for the disorder indicate that this condition may be associated with autoantibodies against glutamic acid decarboxylase (GAD), an enzyme that converts the excitatory neurotransmitter glutamate to the inhibitory neurotransmitter gamma-aminobutyric acid (GABA). Anti-GAD autoantibodies could result in excess excitatory neurotransmitters, leading to the seizures and other symptoms observed in patients with Batten disease. The pathogenic potential of GAD autoantibodies is examined in light of what is known for other autoimmune disorders, such as multiple sclerosis, SPS, Rasmussen encephalitis, and type 1 diabetes, and may have radical implications for diagnosis and management of Batten disease.

    Bile acids regulate the expression of intestinal bile acid transporters and are natural ligands for nuclear receptors controlling inflammation. Accumulating evidence suggests that signaling through these receptors is impaired in inflammatory bowel disease. We investigated whether tauroursodeoxycholic acid (TUDCA), a secondary bile acid with cytoprotective properties, regulates ileal nuclear receptor and bile acid transporter expression and assessed its therapeutic potential in an experimental model of Crohn's disease (CD). Gene expression of the nuclear receptors farnesoid X receptor, pregnane X receptor and vitamin D receptor and the bile acid transporters apical sodium-dependent bile acid transporter and organic solute transporter α and β was analyzed in Caco-2 cell monolayers exposed to tumor necrosis factor (TNF)α, in ileal tissue of TNF(ΔARE/WT) mice and in inflamed ileal biopsies from CD patients by quantitative real-time polymerase chain reaction. TNF(ΔARE/WT) mice and wild-type littermates were treated with TUDCA or placebo for 11 weeks and ileal histopathology and expression of the aforementioned genes were determined. Exposing Caco-2 cell monolayers to TNFα impaired the mRNA expression of nuclear receptors and bile acid transporters, whereas co-incubation with TUDCA antagonized their downregulation. TNF(ΔARE/WT) mice displayed altered ileal bile acid homeostasis that mimicked the situation in human CD ileitis. Administration of TUDCA attenuated ileitis and alleviated the downregulation of nuclear receptors and bile acid transporters in these mice. These results show that TUDCA protects bile acid homeostasis under inflammatory conditions and suppresses CD-like ileitis. Together with previous observations showing similar efficacy in experimental colitis, we conclude that TUDCA could be a promising therapeutic agent for inflammatory bowel disease, warranting a clinical trial.Laboratory Investigation advance online publication, 6 February 2017; doi:10

    BACKGROUND--An association between asthma and gastro-oesophageal reflux is well recognised but the underlying mechanism is unclear. One suggestion is that gastric juice is aspirated into the tracheal and upper airways but detection of these events is difficult and involves radioisotopic studies. A new method of making direct measurements of tracheal and oesophageal pH over a 24 hour period is described, together with its application to patients with asthma. METHODS--The technique involves insertion of simultaneous tracheal and oesophageal pH probes under general anaesthesia. Continuous monitoring of pH over a 24 hour period is possible, permitting comparison with peak flow readings during wakefulness and at night should the patient be disturbed. Representative data from four patients with asthma (mean FEV1 62% predicted) and symptomatic gastro-oesophageal reflux, together with data from three non-asthmatics, is presented. RESULTS--Thirty seven episodes of gastro-oesophageal reflux lasting more than five minutes were recorded. Of these, five were closely followed by a fall in tracheal pH from a mean (SE) of 7.1 (0.2) to 4.1 (0.4) and a fall in peak expiratory flow (PEFR) of 84 (16) l/min. When gastro-oesophageal reflux occurred without tracheal aspiration the fall in PEFR was 8 (4) l/min. CONCLUSIONS--This new technique was well tolerated and allowed quantitation of the number, duration, and timing of episodes of tracheal micro-aspiration. Unlike acid reflux without aspiration, these events appear to be related to significant acute changes in lung function in asthmatic patients. Further studies with this new method may elucidate the role of gastro-oesophageal reflux in asthma. Images PMID:7701464

    Studies of oxidative damage during the progression of Alzheimer's disease (AD) suggest its central role in disease pathogenesis. To investigate levels of nucleic acid oxidation in both early and late stages of AD, levels of multiple base adducts were quantified in nuclear and mitochondrial DNA from the superior and middle temporal gyri (SMTG), inferior parietal lobule (IPL), and cerebellum (CER) of age-matched normal control subjects, subjects with mild cognitive impairment, preclinical AD, late-stage AD, and non-AD neurological disorders (diseased control; DC) using gas chromatography/mass spectrometry. Median levels of multiple DNA adducts in nuclear and mitochondrial DNA were significantly (p ≤ 0.05) elevated in the SMTG, IPL, and CER in multiple stages of AD and in DC subjects. Elevated levels of fapyguanine and fapyadenine in mitochondrial DNA suggest a hypoxic environment early in the progression of AD and in DC subjects. Overall, these data suggest that oxidative damage is an early event not only in the pathogenesis of AD but is also present in neurodegenerative diseases in general. Levels of oxidized nucleic acids in nDNA and mtDNA were found to be significantly elevated in mild cognitive impairment (MCI), preclinical Alzheimer's disease (PCAD), late-stage AD (LAD), and a pooled diseased control group (DC) of frontotemporal dementia (FTD) and dementia with Lewy bodies (DLB) subjects compared to normal control (NC) subjects. Nucleic acid oxidation peaked early in disease progression and remained elevated. The study suggests nucleic acid oxidation is a general event in neurodegeneration.

    The accumulation of amyloid-beta and concomitant oxidative stress are major pathogenic events in Alzheimer's disease. Indole-3-propionic acid (IPA, OXIGON) is a potent anti-oxidant devoid of pro-oxidant activity. IPA has been demonstrated to be an inhibitor of beta-amyloid fibril formation and to be a potent neuroprotectant against a variety of oxidotoxins. This review will summarize the known properties of IPA and outline the rationale behind its selection as a potential disease-modifying therapy for Alzheimer's disease.

    Crohns disease is an inflammatory bowel disease that can have a significant impact on the health of those afflicted. The etiology of the disease is unknown, but genetic, environmental, dietary, and immunological factors are thought to be involved. Multiple nutrients can become depleted during active disease due to inadequate intake or malabsorption. Preventing these deficiencies is paramount in the care of those suffering from Crohns disease. Often the traditional treatments (medications) have limited effectiveness and negative side effects that inhibit their use. Enteral nutrition has promising therapeutic benefits, but its use is often limited to the pediatric population due to poor patient acceptability. Omega-3 fatty acids have been investigated for their anti-inflammatory properties as an alternative to traditional care. This article reviews the etiology of Crohns disease, nutritional deficiencies, traditional treatments, and the use of omega-3 fatty acids in the prevention of Crohns recurrence. The results from clinical trials have been conflicting, but a new fish oil preparation that limits the side effects of traditional fish oil therapy shows promise as an adjunctive treatment for Crohns disease. Continued research is needed to validate these findings.

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

    Amino acids are the basic constituents of living organisms, and have both a structural and an active dynamic role in tissue and cell physiology. Human tears contain 23 amino acids, the relative proportion of which may change with the different physiological states of the eye surface. In this review, we present a collection of data from the published literature that indicate an active role of amino acids in the maintenance of eye surface homeostasis. Moreover, another series of published clinical data indicate that supplementation of amino acids, either as food supplements or as a topical treatment in enriched eye drops, is beneficial to the eye surface, and may improve its healing in cases of eye surface disease due to different causes.

    Background Newborns sleep about 80% of the time. Gastroesophageal reflux (GER) disease is prevalent in about 10% of NICU infants. Concurrent polysomnography and pH-impedance studies clarify relationship of GER with sleep. Aims To characterize spatio-temporal and chemical characteristics of impedance-positive GER and define symptom associations in sleep and wake states in symptomatic neonates. We hypothesized that frequency of impedance-positive GER events and their association with cardiorespiratory symptoms is greater during sleep. Methods Eighteen neonates underwent concurrent polysomnography with pH-impedance study. Impedance-positive GER events (weakly acidic or acidic) were categorized between sleep vs. wake states: Symptom Index = # of symptoms with GER/total symptoms*100, Symptom Sensitivity Index = # of GER with symptoms/Total GER*100 and Symptom Association Probability = [(1-Probability of observed association between reflux and symptoms)*100]). Results We analyzed 317 GER events during 116 hours of polysomnography. During wake vs. sleep respectively, the median (interquartile range) frequency of impedance-positive GER was 4.9(3.1–5.8) vs. 1.4(0.7–1.7)events/hour (P<0.001), proximal migration was 2.6(0.8–3.3) vs. 0.2(0.0–0.9)events/hour (P<0.001); Symptom Index for cardiorespiratory symptoms for impedance-positive events was 22.5 (0–55.3) vs. 6.1(0–13), P=0.04 while Symptom Sensitivity Index was 9.1(0–23.1) vs. 18.4 (0–50), P=0.04 though Symptom Association Probability was similar, (P=0.68). Conclusions Contrary to our hypothesis, frequency of GER in sleep is lesser; however, spatio-temporal and chemical characteristics of GER and symptom generation mechanisms are distinct. For cardiorespiratory symptoms during sleep, lower Symptom Index entails evaluation for etiologies other than GER disease, higher Symptom Sensitivity Index implies heightened esophageal sensitivity and similar Symptom Association Probability indicates other mechanistic

    2015-01-01

    With the high prevalence of obesity, diabetes, and other features of the metabolic syndrome in United States, nonalcoholic fatty liver disease (NAFLD) has inevitably become a very prevalent chronic liver disease and is now emerging as one of the leading indications for liver transplantation. Insulin resistance and derangement of lipid metabolism, accompanied by activation of the pro-inflammatory response and fibrogenesis, are essential pathways in the development of the more clinically significant form of NAFLD, known as nonalcoholic steatohepatitis (NASH). Recent advances in the functional characterization of bile acid receptors, such as farnesoid X receptor (FXR) and transmembrane G protein-coupled receptor (TGR) 5, have provided further insight in the pathophysiology of NASH and have led to the development of potential therapeutic targets for NAFLD and NASH. Beyond maintaining bile acid metabolism, FXR and TGR5 also regulate lipid metabolism, maintain glucose homeostasis, increase energy expenditure, and ameliorate hepatic inflammation. These intriguing features have been exploited to develop bile acid analogues to target pathways in NAFLD and NASH pathogenesis. This review provides a brief overview of the pathogenesis of NAFLD and NASH, and then delves into the biological functions of bile acid receptors, particularly with respect to NASH pathogenesis, with a description of the associated experimental data, and, finally, we discuss the prospects of bile acid analogues in the treatment of NAFLD and NASH.

    Urinary tract infections (UTI) are a common condition in children. Vesicoureteral reflux (VUR) represents a common associated condition with childhood UTI. UTI susceptibility appears to have a genetic component based on family and UTI cohort studies. Targeted analysis of innate immune system genetic variations indicate that these variations are important in UTI susceptibility. In this overview, we discuss how current cohorts and genetic strategies can be implemented to discover new susceptibility loci in patients with UTI. PMID:26848692

    This study investigated the relationship between depression, somatization, anxiety, personality, and laryngopharyngeal reflux (LPR). We prospectively analyzed 231 patients with symptoms with LPR using the laryngopharyngeal reflux symptom index and the reflux finding score. Seventy nine (34.2%) patients were diagnosed with LPR. A significant correlation was detected between the presence of LPR and total scores on the Patient Health Questionnaire-9 (5.6±5.3 vs. 4.0±4.6, p=0.017) and the 7-item Generalized Anxiety Disorder Scale (4.3±4.9 vs. 3.0±4.5, p=0.041). LPR was significantly more frequent in those with depression than in those without (45.6% vs. 27.0%, p=0.004). A multivariate analysis confirmed a significant association between the presence of LPR and depression (odds ratio, 1.068; 95% confidence interval, 1.011–1.128; p=0.019). Our preliminary results suggest that patients with LPR may need to be carefully evaluated for depression. PMID:28326123

    Endoscopic treatment is a minimally invasive treatment for managing patients with vesicoureteral reflux (VUR). Although several bulking agents have been used for endoscopic treatment, dextranomer/hyaluronic acid is the only bulking agent currently approved by the U.S. Food and Drug Administration for treating VUR. Endoscopic treatment of VUR has gained great popularity owing to several obvious benefits, including short operative time, short hospital stay, minimal invasiveness, high efficacy, low complication rate, and reduced cost. Initially, the success rates of endoscopic treatment have been lower than that of open antireflux surgery. However, because injection techniques have been developed, a recent study showed higher success rates of endoscopic treatment than open surgery in the treatment of patients with intermediate- and high-grade VUR. Despite the controversy surrounding its effectiveness, endoscopic treatment is considered a valuable treatment option and viable alternative to long-term antibiotic prophylaxis. PMID:23646052

    Charcot-Marie-Tooth disease type 1A (CMT1A) is a disease for which no drug treatments are available. Passage et al. reported that ascorbic acid reduced the mRNA level of PMP22, improved motor function and increased the numbers of myelinated peripheral nerve axons in a mouse model of CMT1A. Based on these results, five clinical trials were undertaken at different centers worldwide. However, none of them demonstrated significant effectiveness. Although these outcomes were disappointing, these studies have provided many useful insights for conducting the next randomised controlled trial for CMT1A.

    Symptomatic gastroesophageal reflux disease is common in our experience after vertical banded gastroplasty. Our aim was to determine the safety and efficacy of Roux-en-Y gastric bypass in the treatment of symptomatic gastroesophageal reflux disease complicating vertical banded gastroplasty. We evaluated prospectively collected data on 25 patients who underwent revisional bariatric surgery because of severe gastroesophageal reflux disease after vertical banded gastroplasty. Only 4 of 25 patients had gastroesophageal reflux disease symptoms prior to vertical banded gastroplasty. Endoscopic findings in 24 patients included esophagitis (58%), Barrett's esophagus (28%), pouchitis (29%), and gastritis (21%);7 (28%) of 25 patients had evidence of stenosis at the pouch outlet. Mean follow-up (complete in all 25) after Roux-en-Y gastric bypass was 37 +/- 7 months (range 3 to 102 months). There were no deaths. Postoperative complications occurred in six patients: pneumonia in two, wound infection in two, prolonged drainage of the defunctionalized stomach via gastrostomy in one, and fever in one. Median hospitalization was 7 days (range 5 to 43 days). At follow-up (37 +/- 7 months), 24 (96%) of 25 are completely or almost completely symptom free. Body mass index was 33 +/- 2 kg/m(2) before and 28 +/- 2 kg/m(2) after Roux-en-Y gastric bypass (P = 0. 001). Symptoms of gastroesophageal reflux disease are common after vertical banded gastroplasty. Conversion to Roux-en-Y gastric bypass is safe, relieves gastroesophageal reflux disease, and promotes further weight loss. Moreover, maladaptive eating (vomiting, and so forth) induced by vertical banded gastroplasty is relieved.

    Fatty acids, in addition to its known energy value and its structural function, have other beneficial properties. In particular, the polyunsaturated fatty acids omega-3 acting on the cardiovascular apparatus through many channels exerting a protective effect against cardiovascular risk. The benefits associated with the reduction in cardiac mortality and sudden death particular, are related to the incorporation of EPA and DHA in phospholipid membrane of cardiomyocytes. An index is established that relates the percentage of EPA + DHA of total fatty acids in erythrocytes and risk of death from cardiovascular disease may layering in different degrees. Therefore, the primary source of fatty fish w-3 PUFA, behaves like a reference food in cardiosaludables diets.

    Bile reflux has been implicated in the pathogenesis of Barrett's oesophagus but evaluation remains difficult. Bilitec 2000 is an ambulatory system that detects bilirubin based on its spectrophotometric properties. Oesophageal bile exposure was evaluated in three groups of patients. Group 1 (n = 11) were normal controls, group 2 (n = 13) were patients with uncomplicated gastro-oesophageal reflux and group 3 (n = 12) were patients with Barrett's oesophagus. Bile reflux was greater in patients with Barrett's mucosa than in controls or those with uncomplicated reflux. This difference was seen in the supine and interdigestive periods. The percentage of time at which gastric pH was greater than 4 and oesophageal pH was above 7 did not differ between the groups. Bilitec 2000 detects greater bile reflux in patients with Barrett's oesophagus. No corresponding gastric or oesophageal alkaline shift is found. This ambulatory bile reflux monitoring system may be a useful tool in clinical practice.

    The authors analyzed the results of a comprehensive examination of 120 patients with class C6 chronic venous insufficiency according to the CEAP classification, and open trophic ulcers. The patients were subdivided into 2 groups. Group One comprised a total of 75 patients with varicosity, and Group Two consisted of 45 patients with post-thrombotic disease. The localization, intensity and length of the refluxes of blood in the venous system of the affected extremity were determined by means of ultrasonographic angioscanning. Examining the patients with varicosity revealed that in 81.4% the main haemodynamic factor leading to development of the ulcer was a high-intensity, total-subtotal blood reflux along the superficial veins, and in 9.3% - high-intensity superficial and deep refluxes of blood. We failed to determine the blood reflux priority in 9.3% of patients. The trophic ulcers had developed under the effect of low-intensity refluxes of blood in the superficial, deep and perforating veins in elderly patients on the background of heart failure. The most damaging influence on the microcirculatory bed in patients with post-thrombotic disease with recanalization of deep veins is exerted by a high-intensity total reflux of blood in the popliteal and talocrural segments of the venous system of the lower extremities, which was revealed in 68.9% of patients. The developing pathological flow of blood from the muscular-venous pump of the cms into the deep veins of the foot induces perforating insufficiency on the foot and crus, thus creating two zones of venous hypertension above and beneath the ankle. The major factor of trophic ulcers development in patients with segmental obliteration (17.8%) and insufficient recanalization of deep veins (13.3%) was venous hypertension in the distal portions of the affected extremity. Blood refluxes in deep veins of the ankle were of a low-intensity pattern, and played an auxiliary role in development of trophic disorders.

    The causes of renal size reductionin children by 20 percent or more from the age norm include abnormalities of urodynamics of upper (UUT) and lower (LUT) urinary tract, combined with vesicoureteral reflux (VUR) and infra-vesical obstruction (IVO). Several issues regarding diagnosis and choice of treatment in children with small kidneys depending on the severity of functional abnormalities and the presence of comorbidities still remain controversial. 101 children with small kidneys accounting for 3.1% of the entire number of urologic patients admitted to the clinic were followed for 25 years. 78 (77.2%) patients were simultaneously diagnosed as having ipsilateral vesicoureteral reflux (VUR) (2.4% of the total number of hospitalized children). Moreover, contralateral VUR was found in 63% of patients. In 5.1% of children, anomalies of the contralateral kidney were identified: lumbar dystopia (3.8%), duplication of the renal pelvis and ureter (1.3%). Combination with IVO was found in 25.5% of cases. 75 (96%) children with vesicoureteral reflux into the small kidney were operated on. Reconstructive plastic surgery was made in 72 (92%) those patients. Indications for conservative management were identified in patients with intermittent VUR of I-II degree into small kidney or both kidneys. In case of detection of IVO, initial surgery was carried out to eliminate the obstruction. Conservative therapy was aimed at getting rid of the inflammatory process, restoring the function of kidney and bladder, and at the treatment of concomitant vulvovaginitis. In the absence of positive results of 6-8 months of conservative treatment or in case of the negative clinical course, the operation was considered justified. Indications for antireflux surgery were the failure of conservative therapy for intermittent VUR into small kidney or both kidneys, the presence of VUR of III-V degree into one or both kidneys. In cases of bilateral VUR antireflux surgery was performed simultaneously

    Background. There is no gold standard test for diagnosis of gastroesophageal reflux disease (GERD) associated infantile wheezing. Objectives. To evaluate the value of bronchoalveolar lavage (BAL) pepsin assay in diagnosis of GERD in wheezy infants. Methods. Fifty-two wheezy infants were evaluated for GERD using esophageal combined impedance-pH (MII-pH) monitoring, esophagogastroduodenoscopy with esophageal biopsies, and BAL pepsin. Tracheobronchial aspirates from 10 healthy infants planned for surgery without history of respiratory problems were examined for pepsin. Results. Wheezy infants with silent reflux and wheezy infants with typical GERD symptoms but normal MII-pH had significantly higher BAL pepsin compared to healthy control (45.3 ± 8.6 and 42.8 ± 8 versus 29 ± 2.6, P < 0.0001 and P = 0.011, resp.). BAL pepsin had sensitivity (61.7%, 72 %, and 70%) and specificity (55.5%, 52.9%, and 53%) to diagnose GERD associated infantile wheeze compared to abnormal MII-pH, reflux esophagitis, and lipid laden macrophage index, respectively. Conclusion. A stepwise approach for assessment of GERD in wheezy infants is advised. In those with silent reflux, a trial of antireflux therapy is warranted with no need for further pepsin assay. But when combined MII-pH is negative despite the presence of typical GERD symptoms, pepsin assay will be needed to rule out GERD related aspiration. PMID:27516725

    Bisphosphonate therapy has become a standard of therapy for patients with malignant bone disease. Moreover, in vivo preclinical and preliminary clinical data suggest that bisphosphonates may prevent cancer treatment-induced bone loss and the onset of malignant bone disease in patients with early-stage cancer. This comprehensive review critically reports the several preclinical evidences of action of bisphosphonates on osteoclasts, lymphocytes and tumour cells. In addition, all the clinical trials evaluating the effects of principal bisphosphonates on skeletal disease progression in patients with breast cancer, prostate cancer, non-small cell lung cancer and other cancers have been reported. Of the available bisphosphonates, intravenous zoledronic acid has demonstrated the broadest clinical activity and is actually approved for the treatment of bone metastases from any solid tumour in many countries. Renal safety is an important consideration for oncologists who are treating patients with bisphosphonates. This issue and the other topics relating to the safety of bisphosphonates are discussed in this review.

    Huntington's disease (HD) is caused by a dominant mutation that results in an unstable expansion of a CAG repeat in the huntingtin gene leading to a toxic gain of function in huntingtin protein which causes massive neurodegeneration mainly in the striatum and clinical symptoms associated with the disease. Since the mutation has multiple effects in the cell and the precise mechanism of the disease remains to be elucidated, gene therapy approaches have been developed that intervene in different aspects of the condition. These approaches include increasing expression of growth factors, decreasing levels of mutant huntingtin, and restoring cell metabolism and transcriptional balance. The aim of this paper is to outline the nucleic acid-based therapeutic strategies that have been tested to date. PMID:22288011

    Polycystic liver diseases (PLDs) are a group of genetic hereditary cholangiopathies characterized by the development and progressive growth of cysts in the liver, which are the main cause of morbidity. Current therapies are based on surgical procedures and pharmacological strategies, which show short-term and modest beneficial effects. Therefore, the determination of the molecular mechanisms of pathogenesis appears to be crucial in order to find new potential targets for pharmacological therapy. Ductal plate malformation during embryogenesis and abnormal cystic cholangiocyte growth and secretion are some of the key mechanisms involved in the pathogenesis of PLDs. However, the discovery of the presence of bile acids in the fluid collected from human cysts and the intrahepatic accumulation of cytotoxic bile acids in an animal model of PLD (i.e. polycystic kidney (PCK) rat) suggest a potential role of impaired bile acid homeostasis in the pathogenesis of these diseases. On the other hand, ursodeoxycholic acid (UDCA) has emerged as a new potential therapeutic tool for PLDs by promoting the inhibition of cystic cholangiocyte growth in both PCK rats and highly symptomatic patients with autosomal dominant polycystic kidney disease (ADPKD: most common type of PLD), and improving symptoms. Chronic treatment with UDCA normalizes the decreased intracellular calcium levels in ADPKD human cholangiocytes in vitro, which results in the reduction of their baseline-stimulated proliferation. Moreover, UDCA decreases the liver concentration of cytotoxic bile acids in PCK rats and the bile acid-dependent enhanced proliferation of cystic cholangiocytes. Here, the role of bile acids in the pathogenesis of PLDs and the potential therapeutic value of UDCA for the treatment of these diseases are reviewed and future lines of investigation in this field are proposed.

    Multiple water swallows (MWS) stimulates neural inhibition, resulting in abolition of contractions in the esophageal body and complete lower esophageal sphincter relaxation, which is followed by peristalsis and the lower esophageal sphincter contraction. We assessed the relationship between MWS and gastroesophageal reflux in patients with esophageal symptoms and with normal findings by high-resolution manometry (HRM). We retrospectively reviewed the clinical records of patients who underwent HRM and a 24-hour ambulatory impedance-pH study. Correlation between the findings of the impedance-pH study and abnormal MWS responses without motility disorders was evaluated. Independent t-tests were used for statistical analysis. Of 28 patients, 20 (71%) had abnormal MWS responses: four (20%) had abnormal responses during MWS, six (30%) had abnormal responses after MWS, and 10 (50%) had abnormal responses both during and after MWS. Total acid exposure times were significantly longer in patients with abnormal MWS responses than in patients with normal MWS responses. In particular, upright acid exposure time and all reflux percent times were significantly longer in patients with abnormal MWS responses. However, bolus clearance time and longest reflux episode were not different between the two groups. Abnormal MWS responses predicted increased acid exposure times in patients with normal findings of HRM by the Chicago classification.

    Alzheimer's disease (AD) is the leading cause of dementia and the most common neurodegenerative disease in the elderly. Furthermore, AD has provided the most positive indication to support the fact that inflammation contributes to neurodegenerative disease. The exact etiology of AD is unknown, but environmental and genetic factors are thought to contribute, such as advancing age, family history, presence of chronic diseases such as cardiovascular disease (CVD) and diabetes, and poor diet and lifestyle. It is hypothesised that early prevention or management of inflammation could delay the onset or reduce the symptoms of AD. Normal physiological changes to the brain with ageing include depletion of long chain omega-3 fatty acids and brains of AD patients have lower docosahexaenoic acid (DHA) levels. DHA supplementation can reduce markers of inflammation. This review specifically focusses on the evidence in humans from epidemiological, dietary intervention, and supplementation studies, which supports the role of long chain omega-3 fatty acids in the prevention or delay of cognitive decline in AD in its early stages. Longer term trials with long chain omega-3 supplementation in early stage AD are warranted. We also highlight the importance of overall quality and composition of the diet to protect against AD and dementia.

    1998-01-01

    BACKGROUND—This study was designed to determine prospectively the rate of cough before and after laparoscopic Nissen fundoplication performed for the control of gastro-oesophageal reflux disease.
METHODS—One hundred and ninety five consecutive patients (76 men) of mean (SD) age 46.9 (14.1) years with proven gastro-oesophageal reflux disease, who were either on long term omeprazole (n = 187) or who had not responded to a trial of omeprazole (n = 8), took part in the study which was carried out in a university teaching hospital that included a regional respiratory referral centre. Patients underwent oesophageal manometry, 24 hour oesophageal pH testing, and symptom score evaluation by an independent observer before and six months after laparoscopic Nissen fundoplication.
RESULTS—One hundred and thirty three patients presented with reflux symptoms and 62 with respiratory symptoms; 68% of patients complained of cough before surgery (86% with respiratory symptoms, 60% with gastrointestinal symptoms). The percentage reflux time in 24 hours fell significantly (p<0.0001) from a mean (SD) of 9.38 (10.99)% to 1.22 (2.92)%, lower oesophageal sphincter tone rose significantly (p<0.0001) from a mean (SD) of 7.71 (5.90) mm Hg to 21.74 (10.84) mm Hg, and the cough score fell from a median value of 8.0 (IQR 12.0) to 0 (IQR 3) following surgery. Of the patients with cough, 51% were cough free after surgery and 31% improved. The patients with respiratory symptoms had a higher cough score before (median 12.0 (IQR 5.5) versus 4.0 (IQR 8.75), p<0.0001) and after surgery (median 1 (7.5) versus 0.0 (IQR 1.0), p = 0.0045) than those with gastrointestinal symptoms.
CONCLUSIONS—Patients who present to gastroenterologists with severe reflux commonly complain of cough. Laparoscopic Nissen fundoplication is effective in the control of cough in patients with gastro-oesophageal reflux disease, with or without primary respiratory disease.

    Background The aetiology and clinical impact of ineffective oesophageal motility (IEM) remain poorly understood, but the condition is thought to worsen supine gastro-oesophageal acid reflux (GERD). Aims In this retrospective cohort analysis of symptomatic patients with abnormal oesophageal acid exposure, we sought to determine any clinical or functional characteristics that would distinguish those with normal peristalsis from those with IEM, defined using the Chicago classification. We hypothesised that the impaired oesophageal clearance in IEM would be contributing to more severe degrees of pathological acid exposure, as well as clinical and endoscopic GERD severity. Methods Consecutive symptomatic patients with GERD underwent clinical, endoscopic and functional evaluation that included high-resolution impedance manometry (HRIM) and ambulatory pH monitoring performed ‘off’ acid suppressive therapy. Results Of the 114 patients with abnormal oesophageal acid exposure, 71 had normal oesophageal motility by HRIM and 43 were diagnosed with IEM (38% prevalence). Age, gender and symptom duration were similar between the two groups. Both groups had similar magnitude and frequency of symptoms, making a distinction clinically impossible. Endoscopically, the two groups had similar rates of erosive disease, hiatal hernia and Barrett's oesophagus. Ambulatory pH, proton pump inhibitor (PPI) dosage and PPI response rates were also similar. Nevertheless, patients with IEM had significantly more impairment of oesophageal clearance (mean 56.9±6.4) than those with normal motility (mean 32.4±5.0) (p<0.003). Conclusions Symptomatic patients with IEM exhibit significant impairment of oesophageal clearance but are otherwise clinically indistinguishable from those with normal oesophageal motility and have a similar prevalence of erosive disease and pathological acid exposure.

In 28 children (35%) reflux and obstructive nephropathy was a cause of renal failure. In 5 children the disease was secondary to the neurogenic bladder. The incidence of these nephropathies in our population was constant in the analyzed years. In our group there were 2 neonates and 7 adolescent who were diagnosed with nephropathy as late as in the endstage phase. Boys with posterior urethral valve required renal replacement therapy earlier (146 +/- 55 months). We conclude that obstructive and reflux nephropathy are still the essential cause of end stage renal disease in children.

    There is a large and increasing global burden of cardiovascular disease (CVD). The Indian subcontinent may be one of the regions with the highest burden of CVD in the world. With affluence and urbanization, fat intake, especially saturated fat, is increasing. Vitamins have beneficial effects which are useful to the heart, but do not provide the all-round cardioprotection that is required. Hence, there is a perceived need of nutritional supplement that is rich in these essential nutrients. Studies have shown multifactorial cardio-protective actions of ω-3 fatty acids. A cardioceutical contains all the essential nutrients, vitamins, and minerals including ω-3 fatty acids in the right proportion that will provide all-round protection to the heart.

    An investigation of "mysterious" disease due to hydrocyanic acid (HCN) poisoning in livestock in this state was carried out. Detailed clinicopathological and pathological studies were conducted. Characteristic signs of acute tympany followed with profuse frothing, convulsions and dyspnea were recorded. Cynosis of the mucosa with characteristic anoxemic tissue changes and a high concentration of HCN in rumen content, feed and skeletal muscles were recorded. These were sufficient to establish the diagnosis. Successful treatment with a specific antidote was achieved, and further morbidity and mortality was checked.

    The level of beta-aminoisobutyric acid (beta-AIB), a thymine catabolite, has been measured in urine samples of 160 healthy individuals, 28 patients with renal, 27 patients with cardiovascular and 27 patients with hematological diseases and of 36 tumor patients. No significant difference in the prevalence of high excretors of beta-AIB between patients with cancer, renal and cardiovascular diseases and the healthy group was found, whereas all but two patients with hematological diseases were high excretors. Urinary beta-AIB shows a reverse correlation with the hemoglobin level and erythrocyte count in the cases of anemia, and appears to be directly correlated with the leukocyte count and blast cell content in the cases of leukemia, with its amount decreasing two to five-fold with the return of the hematological markers to normal levels after medicinal treatment. Therefore the beta-AIB concentration in urine may be used in combination with hematological indicators in assessing the disease status and in monitoring of the treatment response.

    It is estimated that in Europe 10% of adults suffer from chronic sinusitis. Chronic sinusitis can be caused by many different diseases that share chronic inflammation of the sinuses as a common symptom. Rhinitis can be caused by stomach acid coming up from the stomach into the esophagus, which successively can result in chronic sinusitis. The current gold standard for diagnosing GERD is--bothersome for the patient--24 h esophageal pH monitoring. This method can be unpleasant for the patients, which makes it less acceptable. Because of that the criteria for symptomatic GERD were made an alternative diagnostic way. We acknowledge that the presence of heartburn and stomach acid coming up from the stomach into the esophagus at least once a week can be diagnosed as symptomatic GERD. The aim of the study is the assessment of the frequency of symptomatic GERD in patients operated because of chronic sinusitis and impact of symptomatic GERD on the follow-up treatment up to 12 months after endoscopic nasal surgery. The authors analysed 144 patients operated at the JUCM Otolaryngological Clinic in Kraków between 2011 and 2013 because of sinusitis. The inclusion criteria were: diagnosed chronic sinusitis, indications for endoscopic sinus surgery, and a written consent for the research. Each patient was examined laryngologically and surveyed. Patients were divided into two groups: with and without symptomatic GERD. We analysed the symptoms in patients treated for sinusitis with or without GERD before, between 3 and 6 as well as in the 12th month after endonasal surgery. Moreover, we analysed the intensity of the global symptoms (expressed in the VAS scale) and separately for each of the 13 symptoms of chronic sinusitis (expressed on a scale 0 - 3). We established that 33 out of the 144 patients (22.9%) qualified for the first survey reported the symptoms of GERD. In the second survey, which was conducted between 3 and 6 month after ESS, 24 out of 119 (20%) people reported the

    A thermal model of a single Ultralight Fabric Reflux Tube (UFRT) was constructed and tested against data for an array of such tubes tested in the NASA-JSC facility. Modifications to the single fin model were necessary to accommodate the change in radiation shape factors due to adjacent tubes. There was good agreement between the test data and data generated for the same cases by the thermal model. The thermal model was also used to generate single and linear array data for the lunar environment (the primary difference between the test and lunar data was due to lunar gravity). The model was also used to optimize the linear spacing of the reflux tubes in an array. The optimal spacing of the tubes was recommended to be about 5 tube diameters based on maximizing the heat transfer per unit mass. The model also showed that the thermal conductivity of the Nextel fabric was the major limitation to the heat transfer. This led to a suggestion that the feasibility of jacketing the Nextel fiber bundles with copper strands be investigated. This jacketing arrangement was estimated to be able to double the thermal conductivity of the fabric at a volume concentration of about 12-14%. Doubling the thermal conductivity of the fabric would double the amount of heat transferred at the same steam saturation temperature.

    Alzheimer's disease prevalence has reached epidemic proportion with very few treatment options, which are associated with a multitude of side effects. A potential avenue of research for new therapies are protons, and their associated receptor: acid-sensing ion channels (ASIC). Protons are often overlooked neurotransmitters, and proton-gated currents have been identified in the brain. Furthermore, ASICs have been determined to be crucial for proper brain function. While there is more work to be done, this review is intended to highlight protons as neurotransmitters and their role along with the role of ASICs within physiological functioning of the brain. We will also cover the pathophysiological associations between ASICs and modulators of ASICs. Finally, this review will sum up how the studies of protons, ASICs and their modulators may generate new therapeutic molecules for Alzheimer's disease and other neurodegenerative diseases.

    The pathophysiology of inflammatory bowel diseases (IBDs) is multifactorial and involves interactions of gut luminal content with mucosal barrier and especially immune cells. Malnutrition is a frequent issue during IBD flares, especially in Crohn's disease (CD) patients, and nutritional support is frequently used to treat malnutrition but also in an attempt to modulate intestinal inflammation. The use of oral or enteral nutrition intervention in IBDs may be effective, alone or in combination with drugs, to achieve and maintain remission. However, standard diets are less effective than new-generation biotherapies and could be improved by supplementation with specific immunomodulatory amino acids. Experimental studies evaluating glutamine, the preferential substrate for enterocytes, are promising. Some clinical studies with oral glutamine in CD are until now disappointing, but new formulations and targeting could enhance glutamine efficacy at the site of mucosal lesions. The role of arginine, involved in nitric oxide and polyamines synthesis, still remains debated. However, the effects of these amino acids in IBD have been poorly documented in humans. Other candidates like glycine, cysteine, histidine, or taurine should also be evaluated in the future.

    Gastroesophageal reflux (GER) with laryngopharyngeal reflux plays a significant role in voice disorders. A significant proportion of patients attending ear, nose, and throat clinics with voice disorders may have gastroesophageal reflux disease (GERD). There is no controlled study of the effect of voice therapy on GERD. We assessed the effect of voice therapy in patients with dysphonia and GERD. Thirty-two patients with dysphonia and GERD underwent indirect laryngoscopy and voice analysis. Esophageal and laryngeal symptoms were assessed using the reflux symptom index (RSI). At endoscopy, esophagitis was graded according to Los Angeles classification. Patients were randomized to receive either voice therapy and omeprazole (20 mg bid) (n=16, mean [SD] age 36.1 [9.6] y; 5 men; Gp A) or omeprazole alone (n=16, age 31.8 [11.7] y; 9 men; Gp B). During voice analysis, jitter, shimmer, harmonic-to-noise ratio (HNR) and normalized noise energy (NNE) were assessed using the Dr. Speech software (version 4 1998; Tigers DRS, Inc). Hoarseness and breathiness of voice were assessed using a perceptual rating scale of 0-3. Parameters were reassessed after 6 weeks, and analyzed using parametric or nonparametric tests as applicable. In Group A, 9 patients had Grade A, 3 had Grade B, and 1 had Grade C esophagitis; 3 had normal study. In Group B, 8 patients had Grade A, 2 had Grade B esophagitis, and 6 had normal study. Baseline findings: median RSI scores were comparable (Group A 20.0 [range 14-27], Group B 19.0 [15-24]). Median rating was 2.0 for hoarseness and breathiness for both groups. Values in Groups A and B for jitter 0.5 (0.6) versus 0.5 (0.8), shimmer 3.1 (2.5) versus 2.8 (2.0), HNR 23.0 (5.6) versus 23.1 (4.2), and NNE -7.3 (3.2) versus -7.2 (3.4) were similar. Post-therapy values for Groups A and B: RSI scores were 9.0 (5-13; P<0.01 as compared with baseline) and 13.0 (10-17; P<0.01), respectively. Ratings for hoarseness and breathiness were 0.5 (P<0.01) and 1.0 (P<0

    Epidemiological studies on Greenland Inuits in the 1970s and subsequent human studies have established an inverse relationship between the ingestion of omega-3 fatty acids [C20–22 ω 3 polyunsaturated fatty acids (PUFA)], blood levels of C20–22 ω 3 PUFA, and mortality associated with cardiovascular disease (CVD). C20–22 ω 3 PUFA have pleiotropic effects on cell function and regulate multiple pathways controlling blood lipids, inflammatory factors, and cellular events in cardiomyocytes and vascular endothelial cells. The hypolipemic, anti-inflammatory, anti-arrhythmic properties of these fatty acids confer cardioprotection. Accordingly, national heart associations and government agencies have recommended increased consumption of fatty fish or ω 3 PUFA supplements to prevent CVD. In addition to fatty fish, sources of ω 3 PUFA are available from plants, algae, and yeast. A key question examined in this review is whether nonfish sources of ω 3 PUFA are as effective as fatty fish-derived C20–22 ω 3 PUFA at managing risk factors linked to CVD. We focused on ω 3 PUFA metabolism and the capacity of ω 3 PUFA supplements to regulate key cellular events linked to CVD. The outcome of our analysis reveals that nonfish sources of ω 3 PUFA vary in their capacity to regulate blood levels of C20–22 ω 3 PUFA and CVD risk factors. PMID:22904344

    The presence of gastric acid plays a critical role in the mechanisms of NSAIDs/aspirin-associated gastric and duodenal mucosal injury and ulceration. The role of gastric acid and its relationship to NSAIDs/aspirin in mucosal damage, ulcer and ulcer complications continues to be an important concern because of the increasing worldwide use of NSAIDs and aspirin. Acid suppression continues to be an important prevention strategy for NSAID-associated gastric and duodenal ulcer and ulcer complications. While a coxib or an NSAID and PPI in combination are considered to have comparable safety profiles, the evidence from direct comparisons in high-risk patients is limited, and the cardiovascular safety of coxibs and NSAIDs remains a concern especially in patients with a high risk of cardiovascular disease. An evaluation of individual gastrointestinal and cardiovascular risks and benefits, selection of the most appropriate NSAID and dose for each particular patient should always be emphasized. Twice daily PPI is more appropriate to protect a patient who is taking NSAIDs twice daily. PPI co-therapy is still recommended in patients receiving dual antiplatelet treatment, although conflicting results have been reported about adverse drug interactions between PPIs and clopidogrel.

    To test whether the presence of gastric adenomas (dysplasia) was associated with gastric reflux of duodenal contents, six patients with familial adenomatous polyposis (FAP) who had gastric adenomas and nine matched FAP patients without gastric adenomas underwent scintigraphic duodeno-gastric reflux scanning. Reflux was graded 0-6, where 0 = no reflux, 1 = intermittent reflux into antrum only, 2 = prolonged reflux into antrum only, 3 = intermittent reflux into body, 4 = prolonged reflux into body, 5 = intermittent reflux into body and fundus, and 6 = prolonged reflux into body and fundus. FAP patients with gastric adenomas had more severe reflux (median 6, range 4-6) than did controls (median 3, range 0-6; P = 0.009, Mann-Whitney U test). These results are consistent with a role for bile in the development of gastric adenomatous polyps and suggest that bile is involved in the dysplasia-carcinoma sequence. PMID:1653358

    Nonalcoholic fatty liver disease (NAFLD) is characterized by hepatic lipid accumulation which starts with simple hepatic steatosis and may progress toward inflammation (nonalcoholic steatohepatitis [NASH]). Fatty acid synthase (FASN) catalyzes the last step in fatty acid biosynthesis, and thus, it is believed to be a major determinant of the maximal hepatic capacity to generate fatty acids by de novo lipogenesis. The aim of this study was to analyze the correlation between hepatic steatosis and inflammation with FASN expression. In vitro incubation of primary human hepatocytes with fatty acids dose-dependently induced cellular lipid-accumulation and FASN expression, while stimulation with TNF did not affect FASN levels. Further, hepatic FASN expression was significantly increased in vivo in a murine model of hepatic steatosis without significant inflammation but not in a murine NASH model as compared to control mice. Also, FASN expression was not increased in mice subjected to bile duct ligation, an experimental model characterized by severe hepatocellular damage and inflammation. Furthermore, FASN expression was analyzed in 102 human control or NAFLD livers applying tissue micro array technology and immunohistochemistry, and correlated significantly with the degree of hepatic steatosis, but not with inflammation or ballooning of hepatocytes. Quantification of FASN mRNA expression in human liver samples confirmed significantly higher FASN levels in hepatic steatosis but not in NASH, and expression of SREBP1, which is the main transcriptional regulator of FASN, paralleled FASN expression levels in human and experimental NAFLD. In conclusion, the transcriptional induction of FASN expression in hepatic steatosis is impaired in NASH, while hepatic inflammation in the absence of steatosis does not affect FASN expression, suggesting that FASN may serve as a new diagnostic marker or therapeutic target for the progression of NAFLD.
