  1. Acid suppression increases rates of Barrett's esophagus and esophageal injury in the presence of duodenal reflux.

    LENUS (Irish Health Repository)

    2012-01-31

    BACKGROUND: The contribution of gastric acid to the toxicity of alkaline duodenal refluxate on the esophageal mucosa is unclear. This study compared the effect of duodenal refluxate when acid was present, decreased by proton pump inhibitors (PPI), or absent. METHODS: We randomized 136 Sprague-Dawley rats into 4 groups: group 1 (n = 33) were controls; group 2 (n = 34) underwent esophagoduodenostomy promoting "combined reflux"; group 3 (n = 34) underwent esophagoduodenostomy and PPI treatment to decrease acid reflux; and group 4, the \\'gastrectomy\\' group (n = 35) underwent esophagoduodenostomy and total gastrectomy to eliminate acid in the refluxate. Esophaguses were examined for inflammatory, Barrett\\'s, and other histologic changes, and expression of proliferative markers Ki-67, proliferating cell nuclear antigen (PCNA), and epidermal growth factor receptor (EGFR). RESULTS: In all reflux groups, the incidence of Barrett\\'s mucosa was greater when acid was suppressed (group C, 62%; group D, 71%) than when not suppressed (group B, 27%; P = 0.004 and P < .001). Erosions were more frequent in the PPI and gastrectomy groups than in the combined reflux group. Edema (wet weight) and ulceration was more frequent in the gastrectomy than in the combined reflux group. Acute inflammatory changes were infrequent in the PPI group (8%) compared with the combined reflux (94%) or gastrectomy (100%) groups, but chronic inflammation persisted in 100% of the PPI group. EGFR levels were greater in the PPI compared with the combined reflux group (P = .04). Ki-67, PCNA, and combined marker scores were greater in the gastrectomy compared with the combined reflux group (P = .006, P = .14, and P < .001). CONCLUSION: Gastric acid suppression in the presence of duodenal refluxate caused increased rates of inflammatory changes, intestinal metaplasia, and molecular proliferative activity. PPIs suppressed acute inflammatory changes only, whereas chronic inflammatory changes persisted.

    The relationship between chronic obstructive pulmonary disease (COPD) exacerbations and gastroesophageal reflux (GER) has been investigated less than asthma-GER. We aimed to evaluate the presence of GER in patients with COPD and its impact on exacerbations. We included 24 patients with stable mild-moderate stage COPD and 19 volunteers as the control group. We conducted a gastroesophageal reflux disease (GERD) symptom questionnaire, gastroscopy, manometry, and an ambulatory 24-h pH-impedance study. According to the GERD questionnaire, only 5 (20.8%) patients with COPD had typical GER symptoms. According to the 24-h pH-impedance study, the mean DeMeester score (DMS) was 38.1 ± 34.6 in the COPD group and 13.3 ± 16.8 in the control group (p = 0.01). The acid reflux (DMS > 14.7) rate was higher in patients with COPD than in controls (73.9% vs 26.3%, p = 0.01). The symptom association probability positivity rate was 17.4% (n = 4) in the COPD group, which was similar to the controls (p = 0.11). The mean proximal extension rate of reflux (Z 17 cm) was 26.4 ± 12.9% in the COPD group. The proximal extent of reflux was positively correlated with the number of COPD exacerbations per year (p = 0.03, r = 0.448). In the motility results, only 2 (20%) patients in the control group had a minor motility disorder. Seventeen (70.8%) patients in the COPD group had a minor motility disorder, and 4 (16.7%) had major motility disorders (p gastroesophageal reflux was frequent in patients with COPD, but only a quarter had typical reflux symptoms.

    Approximately 30% of patients with gastroesophageal reflux disease have symptoms resistant to treatment with proton pump inhibitors (PPIs). Several mechanisms such as esophageal hypersensitivity, increased mucosal permeability, and possibly the position of the gastric acid pocket might underlie a partial response to PPIs. To what extent these mechanisms interact and contribute to PPI-resistant symptoms, however, has not been investigated previously. In 18 gastroesophageal reflux disease patients (9 PPI responders and 9 PPI partial responders), esophageal sensitivity, mucosal permeability, and postprandial reflux parameters were determined during PPI use. Esophageal sensitivity for distension was measured by gradual balloon inflation at 5 and 15 cm above the lower esophageal sphincter. The mucosal permeability of 4 esophageal biopsy specimens per patient was determined in Ussing chambers by measuring the transepithelial electrical resistance and transmucosal flux of fluorescein. Postprandial reflux parameters were determined using concurrent high-resolution manometry/pH impedance after a standardized meal. In addition, the acid pocket was visualized using scintigraphy. No difference in the rate of postprandial acid reflux, in the pH of the acid pocket (PPI responders 3.7 ± 0.7 vs PPI partial responders 4.2 ± 0.4; P = .54), or in the position of the acid pocket was observed in PPI partial responders compared with PPI responders. In addition, the permeability of the esophageal mucosa was similar in both groups, as shown by a similar transepithelial electrical resistance and flux of fluorescein. PPI partial responders had more reflux episodes with a higher mean proximal extent, compared with PPI responders, and were more sensitive to balloon distension, both in the upper and lower esophagus. PPI-resistant symptoms most likely are explained by increased proximal reflux in a hypersensitive esophagus and less likely by increased mucosal permeability or the position of

    Gastroesophageal reflux disease has been associated with poor outcomes following lung transplantation. However, the association between pretransplant reflux and post-transplant readmission, an indicator of early clinical outcome, has not been previously assessed. This was a retrospective cohort study of lung transplant recipients undergoing pretransplant multichannel intraluminal impedance and pH (MII-pH) study off acid suppression at a tertiary care center since 2007. Subjects with pretransplant fundoplication were excluded. Time to readmission was defined as duration from post-transplant discharge to next hospital admission for any reason. Subgroup analysis was performed to exclude elective readmissions. Time-to-event analysis was performed using Cox proportional hazards model, with appropriate censoring. Forty-three subjects (60% men, mean age: 57, median follow-up: 1.7 years) met inclusion criteria for the study. Patient demographics and pretransplant cardiopulmonary function were similar between readmission cohorts. Time to all-cause readmission was associated with increased distal acid episodes (HR: 3.15, p = 0.04) and proximal acid episodes (HR: 3.61, p = 0.008) on impedance, increased acid exposure on pH (HR: 2.22, p = 0.04), and elevated Demeester score (HR: 2.26, p = 0.03). When elective readmissions were excluded, early readmission remained significantly associated with increased proximal acid reflux episodes (HR: 2.49, p = 0.04). All findings were confirmed on Kaplan-Meier analysis. Elevated proximal acid reflux on pretransplant MII-pH testing was associated with early readmission following lung transplantation, even after excluding elective readmissions. Exposure to severe acid reflux has measurable effects on early postoperative outcomes such as readmission, and aggressive early antireflux therapy should be considered. © 2015 John Wiley & Sons Ltd.

    Gastroesophageal reflux (GER) has been associated with idiopathic pulmonary fibrosis (IPF), although the mechanism remains unclear. Gastroesophageal reflux/microaspiration may lead to lung fibrosis, while increased pulmonary workload may also worsen GER. Comparing the GER profile of IPF patients to chronic obstructive pulmonary disease (COPD) patients with similar lung function may help delineate the role of GER in IPF pathogenesis. This was a retrospective cohort study of IPF and COPD patients undergoing pre-lung transplant multichannel intraluminal impedance and pH study (MII-pH) off acid suppression at a tertiary center in 2008-2014. Patients with prior fundoplication were excluded. Baseline demographics, pulmonary function test, and MII-pH results were recorded. Univariate analyses were performed using Fisher's exact (binary variables) and Student's t (continuous variables) tests. Logistic regression was performed to adjust for potential confounders. A total of 90 subjects (54 IPF, 36 COPD) met inclusion criteria. Compared to COPD, IPF patients had increased total reflux episodes (65.9 vs 46.1, p = 0.02), proximal reflux episodes (30.3 vs 20.3, p = 0.04), and prevalence of abnormal total reflux episodes (38.9% vs 16.7%, p = 0.02). On multivariate analyses, abnormal total reflux episodes (OR: 4.9, p = 0.05) and bolus reflux exposure time (OR: 4, p = 0.04) remained significantly associated with IPF. Abnormal reflux was significantly more prevalent among IPF patients after controlling for lung disease severity. Gastroesophageal reflux/microaspiration likely plays a role in fibrosis in IPF. A significant portion of IPF patients had increased non-acid reflux. Therapies aiming to prevent reflux of gastric contents may be more beneficial than antisecretory medications alone in these patients. © 2015 John Wiley & Sons Ltd.

    Gastroesophageal reflux disease is a chronic condition with a high prevalence in western countries. Transient lower esophageal sphincter relaxation episodes and a decreased lower esophageal sphincter pressure are the main mechanisms involved. Currently used drugs are efficient on reflux symptoms, but only as long as they are administered, because they do not modify the reflux barrier. Certain nutrients or foods are generally considered to increase the frequency of gastroesophageal reflux symptoms, therefore physicians recommend changes in diet and some patients avoid bothering foods. This review summarizes current knowledge regarding food and gastroesophageal reflux. For example, fat intake increases the perception of reflux symptoms. Regular coffee and chocolate induce gastroesophageal reflux and increase the lower esophageal exposure to acid. Spicy foods might induce heartburn, but the exact mechanism is not known. Beer and wine induce gastroesophageal reflux, mainly in the first hour after intake. For other foods, like fried food or carbonated beverages data on gastroesophageal reflux is scarce. Similarly, there is few data about the type of diet and gastroesophageal reflux. Mediterranean diet and a very low carbohydrate diet protect against reflux. Regarding diet-related practices, consistent data showed that a "short-meal-to-sleep interval" favors reflux episodes, therefore some authors recommend that dinner should be at least four hours before bedtime. All these recommendations should consider patient's weight, because several meta-analysis showed a positive association between increased body mass index and gastroesophageal reflux disease.

    Human Zonulin, related to the Zonula occludens toxin of Vibrio cholerae, regulates intestinal permeability and is induced in inflammatory disorders of the lower GI tract. Gastroesophageal reflux disease (GERD) is associated with an impairment of epithelial barrier function. Here, we studied expression of zonulin in the gastroesophageal mucosa of 58 patients with typical reflux symptoms and 27 asymptomatic controls. During endoscopy, multiple biopsies from gastroesophageal mucosa were obtained for routine histopathology (Helicobacter pylori-status, inflammation) and gene expression analysis (immunohistochemistry, ELISA). Patients with GERD presented with typical histopathological alterations like elongation of papillae (P=0.015), basal cell hyperplasia (PZonulin was found to be expressed ubiquitously in gastroesophageal mucosa. Mucosal levels in controls ranged between 2.2 and 3.7 ng/microg total protein. Mean values were significantly higher in antrum (3.3+/-1.7 ng/microg) than cardia (2.7+/-1.2n g/microg) and esophagus (2.2+/-1.3 ng/microg) (Pzonulin expression in gastroesophageal mucosa. In conclusion, despite its established role for intestinal permeability, Zonulin seems not to be involved in the regulation of epithelial barrier function in relation to GERD.

    This paper deals with detection and quantification of gastroesophageal reflux. Gastroesophageal reflux (GER) generally refers to a symptom complex consisting of heartburn, regurgitation, and chest pain, the latter of which is often confused with pain of cardiac origin. Gastroesophageal reflux occurs when gastric or duodenal contents enter the esophagus. This phenomenon of symptomatic gastroesophageal reflux has been attributed to a variety of anatomic abnormalities, including loss of the acute cardioesophageal Angle of Hiss, widening of the diaphragmatic hiatus, loss of a normal gastric rosette formed by apposition of the gastric mucosal folds, disruption of the phrenoesophageal ligament, and conversion of the distal paraesophageal pressure from an intra-abdominal to an intrathoracic level. Lower esophageal sphincter (LES) dysfunction has been suggested as a major determinant of gastroesophageal competence. Quantitative scintigraphic studies of gastroesophageal reflux suggest that the LES pressure is the important determinant of gastroesophageal reflux, although some investigators have failed to confirm this role of the LES in gastroesophageal competence

    Many patients with gastroesophageal reflux disease (GERD) have persistent reflux despite treatment with proton pump inhibitors (PPIs). Mixed gas-liquid reflux events are more likely to be perceived as symptomatic. We used esophageal impedance monitoring to investigate whether esophageal gas is processed differently among patients with GERD who do and do not respond to PPI therapy. We performed a prospective study of 44 patients with typical reflux symptoms with high levels of esophageal acid exposure during a 24-hour period; 18 patients were fully responsive, and 26 did not respond to PPI therapy. Twenty-four-hour pH impedance recordings were analyzed for fasting and prandial air swallows and reflux characteristics, including the presence of gas in the refluxate. PPI-refractory patients had a higher number (83.1 ± 12.7 vs 47.8 ± 7.3, P gas-liquid reflux. Symptoms of PPI-refractory patients were more often preceded by mixed gas-liquid reflux events than those of PPI responders. Fasting air swallowing and other reflux characteristics did not differ between patients who did and did not respond to PPIs. Some patients with GERD who do not respond to PPI therapy swallow more air at mealtime than those who respond to PPIs and also have more reflux episodes that contain gas. These factors, combined with mucosal sensitization by previous exposure to acid, could affect perception of symptoms. These patients, who can be identified on standard 24-hour pH impedance monitoring, might be given behavioral therapy to reduce mealtime air swallowing. Copyright © 2013 AGA Institute.

  17. Radiologic diagnosis of gastro-oesophageal reflux

    Fransson, S.G.; Soekjer, H.; Johansson, K.E.; Tibbling, L.

    In 149 patients, a standardized radiologic method for the detection of gastro-oesophageal reflux was applied and compared with the results obtained at endoscopy and by a manometric reflux test. Radiologic reflux was recorded in 53 patients, of whom 25 had reflux without abdominal compression and 51 with compression. At least one of the other two types of examination disclosed pathologic conditions in all but 2 of 53 patients. Oesophagitis was significantly more severe among the patients with reflux observed at radiography. The presence of hiatal incompetence with reflux only to the hiatal hernia but not to the oesophagus was not a strong indicator of gastro-oesophageal reflux disease. Hiatal hernia was present in a significantly larger number of the patients with reflux at radiography than in those without reflux. Increased width of the hiatus gave stronger evidence for reflux disease than in patients with a normal hiatus. Thus, the width of the hiatus also had a bearing on the diagnosis of gastro-oesophageal reflux disease.

    Full Text Available Background: In 4–10 % of patients with gastroesophageal reflux (GER some atypical symptoms are found (cough, hoarseness, globus pharyngeus, dyspnea which are characteristic for laryngopharyngeal reflux (LPR. The signs of LPR can be detected in more than 50 % of dysphonic patients. In the diagnostics of LPR, a meticulous history and a videoendoscopy of the larynx and pharynx are the most important procedures. The diagnosis of LPR can be confirmed by the 24-hour double probe pH monitoring and the treatment test with proton pump inhibitors. The best diagnostic results can be obtained with a combination of several diagnostic procedures.Conclusions: An otorhinolaryngologist can start a treatment test with proton pump inhibitors in a patient in whom a laryngopharyngeal reflux is suspected on the basis of history and laryngopharyngeal endoscopy. A successful treatment requires at least 12 weeks regimen with high doses 20 mg twice a day. In the case of alarm signs and unsuccessful treatment a gastroenterologic intervention is necessary.

    Radionucleotide scintigraphy and esophagoscopy with biopsy were carried out in 101 patients with symptoms strongly suggestive of gastroesophageal reflux (GER) disease. GER was visualized by scintigraphy in 86.1% of the patients. Endoscopic and histologic esophagitis were found in 68.1% and 58.4% of the patients, respectively, whereas both examinations taken together showed evidence of esophagitis in 82%. Histologic evidence of esophagitis was found in nearly all patients with severe endoscopic changes, and in 43.7% of the patients with no endoscopic abnormality. Scintigraphic reflux was demonstrated more frequently (p<0.05) in the patients with severe endoscopic esophagitis (97.5%) than in those with no or only mild endoscopic changes (78.6%). Scintigraphic reflux was found in 91.5% and 78.5% of the patients with and without histologic evidence of esophagitis (p=0.07). 15 of the 18 patients (83.3%) without endoscopic and histologic abnormalities in the esophagus had scintigraphic evidence of reflux. The present study strongly supports the clinical significance of scintigraphy in GER disease and confirms that esophageal biopsy specimens increase the sensitivity of endoscopic evaluation

    1985-01-01

    Vesicoureteral reflux (VUR) is mainly a primary phenomenon due to incompetence of the ureterovesical junction, mostly affecting a pediatric population. During micturition cystourethrography (MCU) reflux into the kidney - intrarenal reflux (IRR) - is occasionally seen. In areas with IRR the kidney surface may subsequently be depressed and the papillae retracted (reflux nephropathy (RN)). VUR may lead to hypertension and/or end-stage renal failure. Most commonly, VUR is discovered during evaluation for urinary tract infection, but it may also be present in patients with hypertension, toxemia of pregnancy, chronic renal failure and proteinuria, and it may be found in siblings of patients with VUR. For the time being VUR is demonstrated at radiographic MCU, whereas RN is diagnosed by demonstration of focal scars and of abnormal parenchymal thickness at urography. In children with VUR and no abnormalities of calyces or parenchymal defects standardized measurement of the parenchymal thickness at three sites may identify kidneys which are likely to develop focal scars. Quantitation of focal scarring should be performed in connection with a measure of the overall kidney size. The occurrence of IRR is dependent of the papillary morphology, intrapelvic pressure and urine flow. There may be an important relationship between renal ischemia and IRR in producing a 'vicious circle of deleterious effects' which, combined with parenchymal extravasation, may lead to RN. Treatment of VUR includes medical and surgical management. Since renal scarring may occur in infancy, prevention should focus on infants and young children. Infants and young children with severe VUR may have normal urograms. Therefore a MCU should also be performed, preferably with the recommended standardized technique. (orig.)

    Stone recurrence is a common late adverse event after ERCP in patients with common bile duct stones (CBDS). Duodenal-biliary reflux (DBR) is considered a major cause of CBDS recurrence. However, specific evidence is still lacking. To investigate the DBR rate in patients with recurrent CBDS after ERCP. A prospective case-control study. A tertiary center. During follow-up, patients with a history of either recurrent CBDS (recurrence group) or nonrecurrent CBDS (control group) were invited to participate in the study. All patients had previously undergone successful CBDS removal by ERCP. Patients in the control group were matched with the recurrence group by age and gender in a 1:1 ratio. Patients with gallbladder stones, hepatolithiasis, remnant CBDS, CBD strictures, or stents were excluded. Standard barium meal examination, MRCP, and enhanced abdominal CT. DBR. Thirty-two patients with a history of recurrent CBDS and 32 matched control subjects were enrolled. Baseline characteristics and parameters regarding the first ERCP were comparable between the 2 groups. The DBR rate was significantly higher in the recurrent than in the control group (68.8% vs 15.6%, P < .001). Multivariate analysis indicated that DBR (OR, 9.59; 95% CI, 2.65-34.76) and acute distal CBD angulation (OR, 5.48; 95% CI, 1.52-19.78) were independent factors associated with CBDS recurrence. DBR rates in patients with no, single, or multiple recurrences were 15.6%, 60.9%, and 88.9%, respectively (P < .001). Intrahepatic bile duct reflux was more common in patients with multiple recurrences. Small sample size. DBR is correlated with CBDS recurrence in patients who had previously undergone ERCP. DBR and acute distal CBD angulation are 2 independent risk factors related to stone recurrence. ( NCT02329977.) Copyright © 2015 American Society for Gastrointestinal Endoscopy.

    Gastro-esophageal reflux disease (GERD)-related chronic cough (CC) may have multifactorial causes. To clarify the characteristics of esophagopharyngeal reflux (EPR) events in CC patients whose cough was apparently influenced by gastro-esophageal reflux (GER), we studied patients with CC clearly responding to full-dose proton pump inhibitor (PPI) therapy (CC patients). Ten CC patients, 10 GERD patients, and 10 healthy controls underwent 24-h ambulatory pharyngo-esophageal impedance and pH monitoring. Weakly acidic reflux was defined as a decrease of pH by >1 unit with a nadir pH >4. In six CC patients, monitoring was repeated after 8 weeks of PPI therapy. The number of each EPR event and the symptom association probability (SAP) were calculated. Symptoms were evaluated by a validated GERD symptom questionnaire. Weakly acidic gas EPR and swallowing-induced acidic/weakly acidic EPR only occurred in CC patients, and the numbers of such events was significantly higher in the CC group than in the other two groups (P pump inhibitor therapy abolished swallowing-induced acidic/weakly acidic EPR, reduced weakly acidic gas EPR, and improved symptoms (all P gas EPR and swallowing-induced acidic/weakly acidic EPR. A direct effect of acidic mist or liquid refluxing into the pharynx may contribute to chronic cough, while cough may also arise indirectly from reflux via a vago-vagal reflex in some patients. © 2011 Blackwell Publishing Ltd.

    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. PMID:24868489

    Little data is available on the risk of gastroesophageal reflux disease in patients diagnosed with Sjögren's syndrome. We identified 4650 Sjögren's syndrome patients between 2000 and 2011 from the National Health Insurance Research Database. Each Sjögren's syndrome patient was matched to 4 controls based on age, sex, and index year, and all subjects were followed up from the index date to December 31, 2011. Cox proportional hazards regression model was used to estimate the risk of gastroesophageal reflux disease. The risk of gastroesophageal reflux disease for Sjögren's syndrome patients was 2.41-fold greater than that for the comparison cohort after adjusting for age, sex, and comorbidities. In age stratified analyses, the youngest Sjögren's syndrome cohort (age: 20-44years old) had the highest risk (HR=3.02; 95% CI=2.48-3.69) and the lowest risk at age ≥65years (HR=1.95; 95% CI=1.61-2.36). Regardless of in subjects with and without comorbidity, Sjögren's syndrome patients had a higher risk than the controls. Sjögren's syndrome subjects with ischemic heart disease, hyperlipidemia and renal disease had the highest risk for gastroesophageal reflux disease compared with the comparison cohort without those diseases (HR=7.67; 95% CI=5.32-11.1). Patients with Sjögren's syndrome have a significantly greater risk of developing subsequent gastroesophageal reflux disease than the general population.

    Urinary stasis in the setting of obstruction provides an opportunistic environment for bacterial multiplication and is a well-established risk factor for UTI. Vesicoureteral reflux (VUR) with delayed upper tract drainage (UTD) on VCUG has been reported to correlate with increased UTI risk. We sought to determine whether delayed UTD can be reliably classified, and whether it correlates with UTI incidence, VCUG, or endoscopic findings. Children undergoing endoscopic surgery for primary VUR (2009-2012) were identified. VUR grade, timing, and laterality were abstracted. Demographics, hydrodistention (HD) grade, reported febrile and culture-proven UTI were assessed. UTD on VCUG was graded on post-void images as 1 = partial/complete UTD or 2 = no/increased UTD. Inter-observer agreement was calculated. Patients were excluded for incomplete imaging or inability to void during VCUG. The cohort included 128 patients (10M, 118F), mean age 4.1 ± 2.1 years. Mean age at diagnosis was 2.8 ± 2.8 years. Mean maximum VUR grade was 3 ± 0.9: 1 (7.8%), 2 (20.3%), 3 (43%), 4 (25.8%), 5 (3.1%). UTD occurred in 45 (35%), and no drainage in 83 (65%) patients. Agreement coefficient between graders was 0.596 (p UTIs from birth to surgery. UTI rate did not differ by UTD status for parent or culture-proven UTI (Table). On multivariate analysis, no patient characteristic was a significant predictor of UTI based on drainage status. Children diagnosed with VUR before 1 year of age had a higher verified UTI rate (p UTI rate and when testing the interaction of drainage and age. We sought to determine whether UTD was an accurate predictor of UTI risk to maximize available prognostic information from a single VCUG. Delayed UTD was not a predictor of infection in our patients, nor was it associated with previously described UTI risk factors, such as VUR timing or grade, and voiding dysfunction. Limitations included the retrospective nature of the study in patients undergoing endoscopic

    2012-02-01

    The p.Gly691Ser variant of the RET protein, resulting from the \\'A\\' allele of the SNP rs1799939 in exon 11 of the RET gene, was recently found to be present in a high proportion of primary vesicoureteric reflux (pVUR) patients in Quebec. We have determined the genotype of this SNP in 221 unrelated index cases of pVUR from the Irish population, in 190 full siblings of 160 of the index cases, and in 592 healthy controls. We found no significant difference in genotype or allele frequencies in patients and controls, and no tendency of affected siblings to share the same genotype. We also found no difference in the presence of additional phenotypic features such as duplex kidneys, between patients with and without the \\'A\\' allele, and no difference in grade of reflux. We find no evidence of any influence of RET SNP rs1799939 on pVUR phenotype.

    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.

    This study was conducted to investigate whether there is a direct association between subjective sleep quality and esophageal acid reflux in patients with gastroesophageal reflux disease. We enrolled patients with classic reflux symptoms for endoscopy and ambulatory pH monitoring. The severity of esophageal mucosal injury was assessed by upper endoscopy. Distal esophageal acid exposure was determined by ambulatory 24-hour pH monitoring. Sleep disturbance was assessed by using the Pittsburgh Sleep Quality Index. In total, 103 patients (53 patients without sleep dysfunction and 50 patients with sleep dysfunction) were studied. Erosive esophagitis was found more in patients with sleep disturbance than in those without sleep disturbance (45% versus 31%, P = 0.04). Abnormal esophageal pH was found more in patients with dysfunction (22%) than in patients without sleep dysfunction (5.7%, P = 0.03). Recumbent acid contact time (%) was greater in patients with sleep disturbance than in those without sleep disturbance (3.7 ± 2.4 versus 1.9 ± 0.9, P = 0.04). Sleep quality score positively correlated with acid contact time (r = 0.32, P = 0.02), prolonged reflux events (r = 0.45, P = 0.008) and longer reflux event (r = 0.28, P = 0.03) during recumbent period. Patients with gastroesophageal reflux disease along with sleep dysfunction are characterized with greater nocturnal acid reflux and more erosive esophagitis. Our study suggests that increased nocturnal acid reflux may play a role in inducing sleep disturbance in patients with gastroesophageal reflux disease.

    Al Talalwah, Narmeen; Woodward, Sue

    Gastro-oesophageal reflux disease (GORD) is defined as an abnormal reflux of the stomach contents into the oesophagus, which provokes symptoms and impairs the quality of life. GORD has a high prevalence and incurs costs to the healthcare system. This is the first paper in a series of three exploring the conservative, medical and surgical treatment of GORD. This first paper presents a review of the effect of smoking and alcohol on reflux symptoms and the impact of smoking and alcohol reduction on symptoms of GORD. A search for English language studies on adults was conducted using three databases, MEDLINE, Embase and the Cochrane Central Register of Controlled Trials (CENTRAL). Eleven relevant studies were included in the review. The effect of alcohol on the stimulation of reflux has been debated over the years in different studies. Some studies state that alcohol consumption induces reflux and moderate amounts exacerbate nocturnal gastro-oesophageal heartburn reflux. However, other studies have found no association between alcohol consumption and reflux. Most reflux occurs during smoking because nicotine causes the lower oesophageal sphincter to relax, which increases the risk of reflux. Similarly, the number of cigarettes smoked is associated with the risk of reflux. Nurses need to be aware of the effect of smoking and alcohol on reflux to provide evidence-based advice to empower patients to change their lifestyle, which results in increased therapeutic compliance and a better clinical status. There is no evidence that reducing alcohol consumption decreases symptoms and only limited evidence on the effectiveness of smoking cessation. Further research into the effectiveness of these lifestyle modifications is therefore required.

    Background The role of sexual activity on gastroesophageal reflux disease (GERD) is an under-recognized concern of patients, and one rarely assessed by physicians. Objective The objective of this article is to determine the influence of sexual activity on the intraesophageal acid exposure and acid reflux events in GERD patients. Methods Twenty-one patients with the diagnosis of GERD were prospectively enrolled. Intraesophageal pH monitoring was recorded for 48 hours with a Bravo capsule. All patients were instructed to have sexual intercourse or abstain in a random order two hours after the same refluxogenic dinner within two consecutive nights. Patients were requested to have sex in the standard “missionary position” and women were warned to avoid abdominal compression. The patients completed a diary reporting the time of the sexual intercourse and GERD symptoms. The percentage of reflux time and acid reflux events were compared in two ways: within 30 and 60 minutes prior to and after sexual intercourse on the day of sexual intercourse and in the same time frame of the day without sexual intercourse. Results Fifteen of 21 GERD patients were analyzed. The percentage of reflux time and number of acid reflux events did not show a significant difference within the 30- and 60-minute periods prior to and after sexual intercourse on the day of sexual intercourse and on the day without sexual intercourse, as well. Conclusion Sexual activity does not predispose to increased intraesophageal acid exposure and acid reflux events. Larger studies are needed to confirm our findings in patients who define reflux symptoms during sexual intercourse. PMID:25452843

    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.

    Full Text Available Gastro-oesophageal reflux disease (GERD is a disorder in which reflux of stomach contents causes troublesome symptoms and/or complications and which affects health-related quality of life. It is one of the commonest disorders and appears to be increasing in incidence. The mechanisms leading to reflux are complex and multifactorial. The lower oesophageal sphincter (LES is an important part of the gastro-oesophageal barrier. Transient LES relaxations (TLESRs lead to reflux as these vagally mediated motor patterns cause relaxation of the LES and also result in oesophageal shortening and inhibition of the crural diaphragm. Heartburn and regurgitation are the characteristic symptoms of GERD. A clinical diagnosis of GERD can be made with typical symptoms. Oesophagitis is seen in a minority of patients with GERD. Lifestyle modification is widely advocated for patients with GERD. For short-term relief of symptoms of mild GERD, antacids/alginates are frequently used but they do not heal oesophagitis. Both histamine 2 receptor antagonists (H2RA and proton pump inhibitors (PPI have been shown to heal and prevent relapse of oesophagitis, although PPIs have been shown to be superior. The PPIs are the recommended first-line therapy for erosive oesophagitis and initial management of non-erosive reflux disease. Maintenance PPI therapy should be given to patients with oesophagitis, those who have recurrence of symptoms after discontinuation of medication and for those with complications of GERD.

    To evaluate the diagnosis and management of reflux and gastro-oesophageal reflux disease (GORD) in infants aged reflux and GORD and their management including prescribing of acid-suppressant medicines (proton pump inhibitors (PPIs) and histamine receptor antagonists (H2RAs)) and counselling, advice or education. Of all infants' visits, 512 (2.7%) included a diagnosis of reflux (n=413, 2.2%) or GORD (n=99, 0.5%). From 2006 to 2016, diagnostic rates decreased for reflux and increased for GORD. Prescribing of acid suppressants occurred in 43.6% visits for reflux and 48.5% visits for GORD, similar to rates of counselling, advice or education (reflux: 38.5%, GORD: 43.4% of visits). Prescribing of PPIs increased (statistically significant only for visits for reflux), while prescribing of H2RAs decreased. Overprescribing of acid suppressants to infants may be occurring. In infants, acid-suppressant medicines are no better than placebo and may have significant negative side effects; however, guidelines are inconsistent. Clear, concise and consistent guidance is needed. GPs and parents need to understand what is normal and limitations of medical therapy. We need a greater understanding of the influences on GP prescribing practices, of parents' knowledge and attitudes and of the pressures on parents of infants with these conditions. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Full Text Available Vesicoureteral reflux (VUR management must be tailored based on the risk for further infections and renal scarring, gender, likelihood of spontaneous resolution, and parental preferences. Because we now understand that sterile VUR is benign and most reflux spontaneously resolves over time, the initial approach in majority of children is non-surgical with continuous antibiotic prophylaxis (CAP and correction of bladder and bowel dysfunction. Despite increasing utilization of CAP over the past four decades, the efficacy of antibiotic prophylaxis has been questioned due to conflicting results of studies plagued with design flaws and inadequate subject sample size. The Randomized Intervention for Children with Vesicoureteral Reflux (RIVUR trial, which was designed to address many of the limitations from previous studies, provided much needed answers. In this review, we sought to describe the controversy surrounding VUR management, highlight the results of RIVUR trial, and discuss how the RIVUR findings impact our understanding of CAP in the management of VUR.

    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

    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.

    To examine the relationship between nocturnal bruxism and gastroesophageal reflux. Controlled descriptive study and double-blind, placebo-controlled, clinical study. Portable pH monitoring, electromyography, and audio-video recordings were conducted during the night in the subjects' home. Ten patients with bruxism and 10 normal subjects were matched for height, weight, age, and sex. They did not have symptoms of gastroesophageal reflux disease. Medication with a proton pump inhibitor (ie, a gastric-acid-inhibiting drug). The bruxism group showed a significantly higher frequency of nocturnal rhythmic masticatory muscle activity (RMMA) episodes (mean +/- SD: 6.7 +/- 2.2 times per hour) and a higher frequency and percentage of time of gastroesophageal reflux episodes with a pH less than 4.0 and 5.0 (0.5 +/- 0.9 and 3.6 +/- 1.6 times per hour and 1.3% +/- 2.5% and 7.4% +/- 12.6%, respectively) than the control group (RMMA episodes: 2.4 +/- 0.9 times per hour; gastroesophageal reflux episodes: 0.0 +/- 0.0 and 0.1 +/- 0.3 times per hour and 0.0% +/- 0.0% and 0.0% +/- 0.0%, respectively). In the bruxism group, 100% of the gastroesophageal reflux episodes with a pH less than 3.0 and 4.0 included both an RMMA episode and an electromyographic burst, the duration of which was approximately 0.5 to 1.0 seconds, probably representing swallowing of saliva. The majority of gastroesophageal reflux episodes with a pH of 4.0 to 5.0 also included both an RMMA episode and an electromyographic burst in the control and bruxism groups (100% +/- 0.0% vs 70.7% +/- 16.5%), again probably due to swallowing of saliva. The remaining minority of gastroesophageal reflux episodes with a pH of 4.0 to 5.0 contained only an electromyographic burst (swallowing of saliva). The frequency of RMMA episodes after the release of the medication from the proton pump inhibitor, which increased the gastric and esophageal pH, was significantly lower than that after administration of the placebo in the control

    Management of gastroesophageal reflux disease (GERD) commonly starts with an empiric trial of proton pump inhibitor (PPI) therapy and complementary lifestyle measures, for patients without alarm symptoms. Optimization of therapy (improving compliance and timing of PPI doses), or increasing PPI dosage to twice daily in select circumstances, can reduce persistent symptoms. Patients with continued symptoms can be evaluated with endoscopy and tests of esophageal physiology, to better determine their disease phenotype and optimize treatment. Laparoscopic fundoplication, magnetic sphincter augmentation, and endoscopic therapies can benefit patients with well-characterized GERD. Patients with functional diseases that overlap with or mimic GERD can also be treated with neuromodulators (primarily antidepressants), or psychological interventions (psychotherapy, hypnotherapy, cognitive and behavioral therapy). Future approaches to treatment of GERD include potassium-competitive acid blockers, reflux-reducing agents, bile acid binders, injection of inert substances into the esophagogastric junction, and electrical stimulation of the lower esophageal sphincter.

    Gastroesophageal reflux disease (GERD) is a condition that develops when the reflux of stomach contents into the esophagus causes troublesome symptoms, esophageal injury, and/or complications. Use of proton pump inhibitors (PPI) remains the standard therapy for GERD and is effective in most patients. Those whose symptoms are refractory to PPIs should be evaluated further and other treatment options should be considered, according to individual patient characteristics. Response to PPIs could be total (no symptoms), partial (residual breakthrough symptoms), or absent (no change in symptoms). Patients experiencing complete response do not usually need further management. Patients with partial response can be treated surgically or by using emerging endoscopic therapies. Patients who exhibit no response to PPI need further evaluation to rule out other causes. PMID:25274499

Cricopharyngeal muscle incoordination, assessed cineradiographically, was revealed in 5 of 41 patients (12%) without and 17 of 43 patients (40%) with gastroesophageal reflux assessed clinically (p<0.05). Thus, there was a postive correlation between dysfunction of the cricopharyngeal muscle and gastroesophageal reflux. There was no correlation with other types of pharyngeal dysfunction.

    Radiological evaluation of esophageal motility and the lower esophageal sphincter has gained increased attention in recent years. Videofluoroscopic investigation of esophageal motor function is superior to static film radiography, as repeated analysis of the videotaped recordings is possible. With emphasis on radiological techniques, normal esophagel physiology and motility and a variety of esophageal motor disorders are discussed in this review paper. Radiological evaluation of gastroesophageal reflux and reflux esophagitis is described. Clinical and radiological findings in esophageal motility disorders and gastroesophageal reflux disease and the radiological efficacy compared to that of manometry and pH-metry are discussed. (orig.)

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

    The involvement of delayed gastric emptying (GE) in the pathophysiology of gastro-esophageal reflux disease (GERD) remains debated and has been to date only assessed using esophageal pH-metry that only detects acidic reflux. We therefore investigated whether delay in GE could impact on liquid, mixed, and gas reflux detected using combined esophageal pH-impedance recording. Thirty consecutive patients were explored with GE and esophageal pH-impedance measurement in the workup of typical symptoms of GERD. Gastric emptying was assessed using the (13) C-octanoic acid breath test and an ambulatory esophageal pH-impedance recording was performed off proton pump inhibitors (PPIs) for 24 h. Gastric emptying was normal in 17 patients and delayed in 13 patients. Delay in GE increased the daily number of liquid/mixed reflux events detected by combined esophageal pH-impedance monitoring, but had no effect of esophageal acid exposure or gas reflux. This translated in increased number of postprandial reflux events, with a longer bolus clearance time and increased esophageal proximal extension. In patient with delayed GE, symptomatic reflux had a higher proximal extension and a longer bolus clearance time compared to symptomatic reflux events from patients with normal GE. Delay in GE increases daily and postprandial liquid/mixed reflux events. Reflux characteristics differently trigger symptoms in patients with normal and delayed GE, and may impact on the therapeutic strategy. © 2013 John Wiley & Sons Ltd.

    Non-erosive reflux disease (NERD) is the most common presentation of gastroesophageal reflux disease. Although acid reflux is the most important cause of symptom generation in NERD patients, non-acid reflux is also associated with reflux symptoms. The temporal relation between symptoms and reflux episodes is of importance in evaluating the results of combined pH-impedance monitoring in NERD patients. Mucosal hypersensitivity and mechanical stimulation due to great volume of non-acid reflux ar...

    The National Ambulatory Medical Care Survey (NAMCS) database was utilized to understand evolving national trends in diagnosis and management of reflux. The NAMCS database was queried for visits related to gastroesophageal reflux diagnosis and management. Analysis performed for time periods 1998-2001, 2002-2005, and 2006-2009 was weighted to provide national estimates of care. Results were compared to previously reported time periods from 1990 to 2001 to evaluate patterns in overall visits, age and ethnicity of patients, provider type, and prescriptions provided. The number of ambulatory visits for reflux increased from 8 684 000 in 1998-2001 to 15 750 000 in 2006-2009. Visits increased across each time period for internal medicine, family, and gastroenterology physicians. Among otolaryngologists, absolute visits increased from 1998-2001 to 2002-2005 but decreased in 2006-2009; difference between these time periods did not reach statistical significance. From 1998-2001 to 2006-2009, reflux medication use increased 233%, with continuing trends toward increased proton pump inhibitor use. Reflux visits have increased across all demographic subgroups studied. Knowledge of these trends may inform further paradigm shifts in diagnosis and management of reflux.

  1. Experimental and theoretical study of reflux condensation

    This thesis studies the separation of gas mixtures in a reflux condenser. also called a dephlegmator. Reflux condensation is separation of a gas mixture, in reflux flow with condensing liquid, under continuous heat removal. A numerical model of a dephlegmator for binary mixtures was developed. The model may readily be extended to multi-component mixtures, as the solution method is based on a matrix solver. Separation of a binary mixture in a reflux condenser test rig is demonstrated. The test facility contains a single-tube test section that was designed and built as part of the project. Test mixtures of propane and n-butane were used, and a total of 15 experiments are reported. Limited degree of separation was achieved due to limited heat transfer area and narrow boiling point range of the test mixture. The numerical model reproduces the experimental data within reasonable accuracy. Deviation between calculated and measured properties is less than 6% of the measured temperature and less than 5% of the measured flow rate. The model is based on mechanistic models of physical processes and is not calibrated or tuned to fit the experimental data. The numerical model is applied to a number of separation processes. These case studies show that the required heat transfer area increases rapidly with increments in top product composition (light component). Flooding limits the amount of reflux liquid. The dephlegmator is suitable for separation of feed mixtures that are rich in light components. The gliding temperature in the dephlegmation process enables utilization of top product as refrigerant, with subsequent energy saving as a result. 61 refs., 50 figs., 34 tabs.

    Alginate rafts (polysaccharide polymers that precipitate into a low-density viscous gel when they contact gastric acid) have been reported to form at the acid pocket, an unbuffered pool of acid that floats on top of ingested food and causes postprandial acid reflux. We studied the location of an alginate formulation in relation to the acid pocket and the corresponding effects on reflux parameters and acid pocket positioning in patients with gastroesophageal reflux disease (GERD). We randomly assigned patients with symptomatic GERD and large hiatal hernias to groups who were given either (111)In-labeled alginate-antacid (n = 8, Gaviscon Double Action Liquid) or antacid (n = 8, Antagel) after a standard meal. The relative positions of labeled alginate and acid pocket were analyzed for 2 hours by using scintigraphy; reflux episodes were detected by using high-resolution manometry and pH-impedance monitoring. The alginate-antacid label localized to the acid pocket. The number of acid reflux episodes was significantly reduced in patients receiving alginate-antacid (3.5; range, 0-6.5; P = .03) compared with those receiving antacid (15; range, 5-20), whereas time to acid reflux was significantly increased in patients receiving alginate-antacid (63 minutes; range, 23-92) vs those receiving antacid (14 minutes; range, 9-23; P = .01). The acid pocket was located below the diaphragm in 71% of patients given alginate-antacid vs 21% of those given antacid (P = .08). There was an inverse correlation between a subdiaphragm position of the acid pocket and acid reflux (r = -0.76, P acid pocket and displaces it below the diaphragm to reduce postprandial acid reflux. These findings indicate the importance of the acid pocket in GERD pathogenesis and establish alginate-antacid as an appropriate therapy for postprandial acid reflux. Copyright © 2013 AGA Institute.

    Full Text Available Aim: This study aimed to identify the differences between primary and secondary vesicoureteric reflux (VUR and the effect of associated bladder abnormalities on kidney function. Patients and Methods: We retrospectively reviewed the medical records of children with VUR who were followed up at King Abdulaziz University Hospital from January 2005 to December 2010. The review included results of radiological investigations and kidney function tests. We used Chi-square test for statistical analysis and paired t-test to compare group means for initial and last creatinine levels. Results: Ninety-nine children were included in this study. Twenty (20.2% had primary VUR, 11 had high-grade VUR, while 9 had low-grade reflux. All children with low-grade VUR had normal dimercaptosuccinic acid (DMSA. Renal scars were present in 72% of the children with high-grade VUR. The mean creatinine levels (initial and last for both groups were normal. Seventy-nine (79.8% children had secondary VUR, which was due to posterior urethral valves (PUV (46.8%, neurogenic bladder caused by meningomyelocele (25.3%, non-neurogenic neurogenic bladder (NNB (21.5%, or neurogenic bladder associated with prune belly syndrome (6.3%. Children with NNB, meningomyelocele and PUV had high creatinine at presentation with no considerable worsening of their kidney functions during the last visit. Renal scars were present in 49.4% of the children with secondary VUR. Conclusion: Children with primary VUR and normal bladder had good-functioning kidneys, while those with secondary VUR associated with abnormal bladder caused by NNB, spina bifida or PUV had abnormal kidney functions. DMSA scans were useful in predicting higher grades of VUR in children with primary reflux.

    Chronic gastroesophageal reflux disease was diagnosed in a 22-year-old female Tennessee Walking Horse that had signs of bruxism and ptyalism. Esophageal ulceration was detected via endoscopy. Compared with the damage to the proximal portions of the esophagus, the severity of the ulceration increased toward the gastroesophageal junction. Esophageal ulceration attributable to chronic gastric acid reflux is usually secondary to pyloric outflow obstruction in horses. In the horse of this report, there was no evidence of either a chronic pyloric or duodenal obstruction that could have resulted in esophageal ulceration. Esophageal ulceration in this horse was attributed to gastroesophageal reflux disease, a common condition in humans in which the underlying abnormality is functional incompetence of the gastroesophageal junction. Treatment is directed at decreasing gastric acidity and protecting the ulcerated mucosa. In the horse of this report, treatment was unsuccessful and the horse was euthanatized; a physical cause of gastroesophageal reflux disease was not identified during an extensive postmortem examination.

    Literature has addressed the increased prevalence of gastroesophageal reflux disease (GERD) in obstructive sleep apnea (OSA). Significant improvement of GERD has been found after OSA treatment. However, precise mechanisms underlying this correlation remain unclear. We examined the association between nocturnal gastroesophageal reflux (GER) and sleep events in patients with coexisting OSA and GERD. A case-crossover study among 12 patients with coexisting moderate-severe OSA and GERD was conducted. Participants underwent simultaneous polysomnography and esophageal impedance and pH monitoring. GER subtypes (ie, acid reflux, non-acid reflux) were defined as outcomes. Respective control time points were selected in all eligible control periods. Each sleep event was assessed individually. Estimated odds ratios (ORs) and 95% confidence intervals (CIs) were analyzed. A p-value of reflux and 28 non-acid reflux. Arousals and awakenings were significantly associated with subsequent GER events. The OR for GER following an arousal was 2.31 (95% CI 1.39-3.68; p  0.05). Both awakening and arousal appear to precipitate any subtype of GER events in patients with coexisting GERD and moderate to severe OSA. However, GER events were significantly less likely to occur after other respiratory events and did not appear to cause sleep-related events. Copyright © 2016 Elsevier B.V. All rights reserved.

    When patients have symptomatic gastroesophageal reflux disease, their symptoms usually respond to conventional therapeutic measures. In some patients, however, the symptoms may persist despite the application of standard treatment regimens. It is in these instances that the clinician may employ extensive diagnostic tests to determine the cause of the patient's complaints. Because the introduction of gastroesophageal scintigraphy, a number of other techniques were employed to evaluate gastroesophageal reflux. These include barium esophagography, barium cineesophagography; endoscopy; esophageal mucosal biopsy; esophageal manometry; the acid-clearance test; and acid-reflux testing. Each of the nonscintigraphic techniques has a limitation either in its sensitivity or in the requirement for endogastric intubation. In addition, with the exception of the scintigraphic method, none of the tests permits quantitation of reflux

    Conventionally, pathological acid exposure (PAE), defined by acid reflux only, is used to identify gastro-esophageal reflux disease (GERD). However, weak acid reflux or non-acid reflux also induces reflux symptoms. Defining abnormal reflux based on all reflux episodes may better identify GERD and would be more useful among patients with atypical GERD symptoms, such as globus. Impedance-pHmetry results of 31 globus patients, off acid suppressants, were analysed. A median of 24 episodes of reflux were observed. Of the reflux episodes, 54% were non-acid reflux and 50% reached the proximal extent. PAE was observed in 6 patients (19%). For 5 patients (16%) without PAE, there was evidence of increased bolus exposure compared to normal controls (an intraesophageal bolus exposure for more than 1.4% of the recording time, defined as pathological bolus exposure, PBE). When GERD was defined by PAE or esophagitis, the prevalence of GERD was 29%. When GERD was defined by PBE, PAE or esophagitis, the prevalence was 42%. PBE identified 13% of the patients who otherwise would have been missed. A significant proportion of patients without PAE had evidence of PBE. PBE may be a more useful definition for identifying patients with abnormal increase in reflux in patients with globus. Further studies are warranted.

    By means of esophageal transit scintigram using 99m Tc-DTPA, 15 patients (13 esophageal carcinomas and 2 cardia carcinomas) were studied, in whom esophagogastric anastomosis was done according to the posterior invagination anastomosis technique we had devised. In all 8 patients with anastomosis at cervical region, gastroesophageal reflux was not seen on both scintigrams before and after meals, and the average pressure gradient of high pressure zone at anastomosis was 39.8 cmH 2 O. In 2 of 7 patients with intrathoracic anastomosis, the scintigram before meals showed severe reflux. and the endoscopic findings showed diffuse and moderate erosion in the esophageal mucosa. The average pressure gradient across the anastomosis was 6.5 cmH 2 O. In these 2 patients, the new fornix with a sharp angle of His was not formed. In the remaining 5 patients with intrathoracic anastomosis, reflux was not seen on the scintigram before meals. However, in 2 of them, the scintigram after meal and endoscopic examination revealed mild reflux and mild esophagitis respectively. Furthermore in one patient very mild reflux was observed only on the scintigram after meals but the endoscopic findings showed the normal esophageal mucosa. In these 5 patients, the average pressure gradient across the anastomosis was 17.0 cmH 2 O, which was significantly higher (p<0.01) than that in 2 patients with severe reflux and was significantly lower (p<0.01) than the mean value of high pressure zone in 8 patients with cervical anastomosis. In conclusion, it is presumed that the formation of a large fornix enough to store food and a sharp angle of His are important factors in maintaining an anti-reflux mechanism. The esophageal transit scintigram was proved to be an excellent technique in detecting and evaluating quantitatively gastroesophageal reflux. (author)

    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. Copyright © 2016 Elsevier Inc. All rights reserved.

    Changes in the expression of mucin genes in the esophageal mucosa associated with uncomplicated gastro-esophageal reflux disease have not been evaluated even though such changes could be associated with reflux-induced mucosal damage. We therefore sought to identify reflux-induced changes in mucin gene expression using a cell line and biopsies from the esophageal mucosa in patients with and without reflux. MUC-1, MUC-3, MUC-4, and MUC-5AC gene expressions were investigated in the HET-1A cell line following exposure to acid (pH 4) and/or bile (120 muM of a bile salt milieu), and in esophageal mucosal biopsies from controls, subjects with non-erosive gastro-esophageal reflux, and subjects with reflux associated with ulcerative esophagitis (erosive). The mucosal biopsies were also evaluated for IL-6 mRNA expression (inflammatory marker) and CK-14 mRNA expression (mucosal basal cell layer marker). Gene expression was determined using real-time reverse transcriptase-polymerase chain reaction analysis. In the cell line studies, there were differences in mRNA levels for all of the evaluated mucins following treatment with either acid or the acid and bile combination. In the studies which evaluated tissue specimens, IL-6 and CK-14 mRNA levels increased according to degree of reflux pathology. The expression of MUC-1 and MUC-4 in mucosa from patients with erosive reflux was lower than in subjects without reflux and in patients with non-erosive reflux, whereas the expression of MUC-3 and MUC-5AC was increased (although these differences did not reach significance at p reflux groups. The correlation between IL-6 and MUC-3 was significant within the control and erosive reflux groups, and the correlation between MUC-1 and MUC-5AC was significant within the erosive reflux group. The results of this study suggest that the profile of mucin expression in the esophageal mucosa is influenced by the pH and composition of the gastro-esophageal reflux. Further work should explore the

    Current diagnostic tests for gastroesophageal reflux disease (GERD) do not consistently measure chronicity of reflux. Mucosal impedance (MI) is a minimally invasive measurement to assess esophageal conductivity changes due to GERD. We aimed to investigate MI pattern in patients with symptoms of extraesophageal reflux (EER) in a prospective longitudinal cohort study. Patients with potential symptoms of EER undergoing esophagogastroduodenoscopy (EGD) with wireless pH monitoring were studied. Participants included those with erosive esophagitis (E+), normal EGD/abnormal pH (E-/pH+), and normal EGD/normal pH (E-/pH-). MI was measured from the site of injury in patients with E+, as well as at 2, 5, and 10 cm above the squamocolumnar junction (SCJ) in all participants. Forty-one patients with symptoms of EER were studied. MI measurements at 2 cm above the SCJ were significantly (P = 0.04) different among the three groups, with MI lowest for E+ and greatest for E-/pH- patients. Although not statistically significant, there is a graded increase in median (interquartile range) MI axially along the esophagus at 5 cm (P = 0.20) and at 10 cm (P = 0.27) above the SCJ, with those with reflux (E+ and E-/pH+) having a lower MI than those without. Patients with symptoms of EER and evidence of acid reflux have an MI lower than those without at 2 cm above the SCJ, with a trend at 5 cm and 10 cm as well. MI may be a tool to assess presence of GERD in patients presenting with EER symptoms. Copyright © 2017 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

    Dental erosion is a complication of gastro-oesophageal reflux disease (GORD) according to the Montreal consensus statement. However, GORD has not been comprehensively characterized in patients with dental erosions and pH-impedance measures have not been reported. Characterize GORD in patients with dental erosions using 24-h multichannel intraluminal pH-impedance measurements (pH-MII) and endoscopy. This single-centre study investigated reflux in successive patients presenting to dentists with dental erosion using pH-MII and endoscopy. Of the 374 patients, 298 (80%) reported GORD symptoms reflux episodes were 71 (63-79), 43 (38-49) and 31 (26-35), respectively. Of the reflux episodes, 19% (17-21) reached the proximal oesophagus. In 241 (69%) patients reflux was abnormal using published normal values for acid exposure time and reflux episodes. No significant associations between the severity of dental erosions and any reflux variables were found. The presence of GORD symptoms and of oesophagitis or a hiatal hernia was associated with greater reflux, but not with increased dental erosion scores. Significant oligosymptomatic gastro-oesophageal reflux occurs in the majority of patients with dental erosion. The degree of dental erosion did not correlate with any of the accepted quantitative reflux indicators. Definition of clinically relevant reflux parameters by pH-MII for dental erosion and of treatment guidelines are outstanding. Gastroenterologists and dentists need to be aware of the widely prevalent association between dental erosion and atypical GORD.

    important risk factor. Negative effects of reflux over dilatation treatment have not yet been demonstrated in the short-term. Nevertheless, this frequent rate of reflux may eventually increase the risk of oesophagitis and Barrett's oesophagus; therefore, we suggest that these effects should be prospectively evaluated in a large number of patients and these patients should be followed-up routinely in terms of the long-term effects of reflux.

    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

    This relationship between gastroesophageal reflux and airway disorders is complex, possibly bidirectional, and not clearly defined. The tools used to investigate gastroesophageal reflux are mostly informative about involvement of gastroesophageal reflux within the gastrointestinal tract, although they are often utilized to study the relationship between gastroesophageal reflux and airway issues with are suspected to occur in relation to reflux. These modalities often lack specificity for reflux-related airway disorders. Co-incidence of gastroesophageal reflux and airway disorders does not necessarily infer causality. While much of our focus has been on managing acidity, controlling refluxate is an area that has not been traditionally aggressively pursued. Our management approach is based on some of the evidence presented, but also often from a lack of adequate study to provide further guidance. Copyright © 2018 Mosby, Inc. All rights reserved.

    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

    This study was designed to determine the protective effect of Rumex Aquaticus Herba extracts containing quercetin-3-β-D-glucuronopyranoside (ECQ) on experimental reflux esophagitis. Reflux esophagitis was induced by surgical procedure. The rats were divided into seven groups, namely normal group, control group, ECQ (1, 3, 10, 30 mg/kg) group and omeprazole (30 mg/kg) group. ECQ and omeprazole groups received intraduodenal administration. The Rats were starved for 24 hours before the experiments, but were freely allowed to drink water. ECQ group attenuated the gross esophagitis significantly compared to that treated with omeprazole in a dose-dependent manner. ECQ decreased the volume of gastric juice and increased the gastric pH, which are similar to those of omeprazole group. In addition, ECQ inhibited the acid output effectively in reflux esophagitis. Significantly increased amounts of malondialdehyde (MDA), myeloperoxidase (MPO) activity and the mucosal depletion of reduced glutathione (GSH) were observed in the reflux esophagitis. ECQ administration attenuated the decrement of the GSH levels and affected the MDA levels and MPO activity. These results suggest that the ECQ has a protective effect which may be attributed to its multiple effects including anti-secretory, anti-oxidative and anti-inflammatory actions on reflux esophagitis in rats.

    Full Text Available In this overview the influence of functional bladder disturbances and of its treatment on the resolution of vesicoureteral reflux (VUR in children is discussed. Historically both bladder dysfunction entities, the overactive bladder (OAB and the dysfunctional voiding (DV, have been described in conjunction with VUR. Treatment of the dysfunction was also considered to influence spontaneous resolution in a positive way. During the last decades, however, papers have been published which could not support these results. Regarding the OAB, a prospective study with treatment of the bladder overactivity with anticholinergics, did not influence spontaneous resolution rate in children with a dysfunction including also the voiding phase, DV and DES (dysfunctional elimination syndrome, most studies indicate a negative influence on the resolution rate of VUR in children, both before and after the age for bladder control, both with and without treatment. However, a couple of uncontrolled studies indicate that there is a high short-term resolution rate after treatment with flow biofeedback. It should be emphasized that the voiding phase dysfunctions (DV and DES are more severe than the genuine filling phase dysfunction (OAB, with an increased frequency of UTI and renal damage in the former groups. To be able to answer the question if treatment of bladder dysfunction influence the resolution rate of VUR in children, randomized controlled studies must be performed.

    Gastro-oesophageal reflux, either singly or in association with postnasal drip and/or asthma is considered to be a cause of chronic cough. The amount and nature of gastro-oesophageal reflux however is often normal with acid suppression having very little, if any therapeutic effect in these patients. This review examines the challenges posed when exploring the reflux-cough link, and discusses the merits and limitations of the proposed mechanisms of reflux leading to cough.

    Background/Aims Available data about reflux patterns and symptom determinants in the gastroesophageal reflux disease (GERD) subtypes off proton pump inhibitor (PPI) therapy are lacking. We aimed to evaluate reflux patterns and determinants of symptom perception in patients with GERD off PPI therapy by impedance-pH monitoring. Methods We retrospectively reviewed the impedance-pH data in patients diagnosed as GERD based on results of impedance-pH monitoring, endoscopy and/or typical symptoms. The characteristics of acid and weakly acidic reflux were evaluated. Symptomatic and asymptomatic reflux were compared according to GERD subtypes and individual symptoms. Results Forty-two patients (22 males, mean age 46 years) were diagnosed as GERD (17 erosive reflux disease, 9 pH(+) non-erosive reflux disease [NERD], 9 hypersensitive esophagus and 7 symptomatic NERD). A total of 1,725 reflux episodes were detected (855 acid [50%], 857 weakly acidic [50%] and 13 weakly alkaline reflux [reflux was more frequently symptomatic and bolus clearance was longer compared with weakly acidic reflux.

Conclusions In patients not taking PPI, acid reflux was more frequently symptomatic and had longer bolus clearance. Symptomatic reflux was more frequently acid and mixed type; however, weakly acidic reflux was associated more with globus. These data suggest a role for impedance-pH data in the evaluation of globus.

    To analyze our series of primary congenital diverticula (PCD) and their association with vesicoureteral reflux. We have taken care of 23 children with PCD. Eleven of them had big diverticula (> 2 cm) and twelve small. In the first group, 4 children had vesicoureteral reflux and 5 in the second group. In group A, ureteral reimplantation was performed at the time of diverticulum excision. Nor diverticula neither refluxes were operated in group B. We analyze separately results in both groups. Group A: Patients were operated including diverticulum excision. There were not recurrences except in one case with Ehler-Danlos Syndrome. No reimplanted ureter showed postoperative reflux. Nevertheless, one case with multiple bladder diverticula without reflux presented reflux after the excision of several diverticula without reimplantation. Group B: Small diverticula did not undergo surgery Spontaneous outcome of reflux was similar to that of the general population without diverticula. Bladder diverticula are frequently associated with vesicoureteral reflux. The presence of reflux is not an absolute condition for surgical or endoscopic treatment. When diverticula are big in size (Group A) the indication for surgery comes from recurrent infection or voiding disorders, not from reflux. If they undergo surgery, ureteral reimplantation is performed in the case they had reflux or for technical reasons like bladder wall weakness. When diverticula are small (Group B) the presence of reflux does not condition treatment, being the rate of spontaneous resolution similar to the general population.

    A prospective randomized study was done on 45 patients to evaluate the effectiveness of the Hill, Nissen or Belsey anti-reflux procedure. All patients had symptoms of GE reflux unresponsive to medical therapy, a + standard acid reflux test (SART), and esophagitis (38/45) or + Burnstein test (7/45). Esophageal symptomatic, radiographic, manometric and pH (SART and 24-hr monitoring) evaluation was done pre- and 154 days (ave.) postsurgery. All procedures improved the symptoms of pyrosis. The best improvement was seen after the Nissen repair. All procedures increased the distal esophageal sphincter (DES) pressures over preoperative levels. The Nissen and Belsey increased it more than the Hill. Sphincter length and dynamics remained unchanged. The Nissen procedure placed more of the manometric sphincter below the respiratory inversion point in the positive pressure environment of the abdomen. The esophageal length was increased by the Nissen and Hill repairs. This was thought to account for the high incidence of temporary postsurgery dysphagia following the Nissen and Hill repairs and the lower incidence following the Belsey repair. Reflux was most effectively prevented by the Nissen repair, as shown by the SART and the 24-hr esophageal pH monitoring, a sensitive measurement of frequency and duration of reflux. The average length of hospital stay was 20 days for Belsey and 12 days for both Nissen and Hill procedure. Postsurgery complications were more common following the thoracic than the abdominal approach. Ability to vomit postrepair was greatest with the Hill and least with the Belsey and Nissen repair. All procedures temporarily increased amount of flatus. It is concluded that the Nissen repair best controls reflux and its symptoms by providing the greatest increase in DES pressure and placing more of the sphincter in the positive abdominal environment. This is accomplished with the lowest morbidity but at the expense of temporary postoperative dysphagia and a 50

    Full Text Available The clinical presentation of noncystic fibrosis bronchiectasis may be complicated by concomitant conditions, including gastro-oesophageal reflux (GOR. Increased acidic GOR is principally caused by gastro-oesophageal junction incompetence and may arise from lower oesophageal sphincter hypotension, including transient relaxations, hiatus hernia, and oesophageal dysmotility. Specific pathophysiological features which are characteristic of respiratory diseases including coughing may further increase the risk of GOR in bronchiectasis. Reflux may impact on lung disease severity by two mechanisms, reflex bronchoconstriction and pulmonary microaspiration. Symptomatic and clinically silent reflux has been detected in bronchiectasis, with the prevalence of 26 to 75%. The cause and effect relationship has not been established, but preliminary reports suggest that GOR may influence the severity of bronchiectasis. Further studies examining the implications of GOR in this condition, including its effect across the disease spectrum using a combination of diagnostic tools, will clarify the clinical significance of this comorbidity.

    The aim of the present study was to investigate the impact of gastro-oesophageal acid reflux on sleep in neonates and, reciprocally, the influence of wakefulness (W) and sleep stages on the characteristics of the reflux (including the retrograde bolus migration of oesophageal acid contents). The pH and multichannel intraluminal impedance were measured during nocturnal polysomnography in 25 infants hospitalised for suspicion of gastro-oesophageal reflux. Two groups were constituted according to whether or not the infants displayed gastro-oesophageal reflux (i.e. a reflux group and a control group). There were no differences between the reflux and control groups in terms of sleep duration, sleep structure and sleep state change frequency. Vigilance states significantly influenced the gastro-oesophageal reflux pattern: the occurrence of gastro-oesophageal reflux episodes was greater during W (59 ± 32%) and active sleep (AS; 35 ± 30%) than during quiet sleep (QS; 6 ± 11%), whereas the mean duration of gastro-oesophageal reflux episodes was higher in QS than in W and AS. The percentage of retrograde bolus migrations of distal oesophageal acid content was significantly higher in AS (62 ± 26%) than in W (42 ± 26%) and QS (4.5 ± 9%). In neonates, gastro-oesophageal reflux occurred more frequently during W, whereas the physiological changes associated with sleep state increase the physiopathological impact of the gastro-oesophageal reflux. The duration of oesophagus-acid contact was greater during sleep; AS facilitated the retrograde migration of oesophageal acid content, and QS was characterised by the risk of prolonged acid mucosal contact. © 2011 European Sleep Research Society.

    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.

    Nocturnal acid reflux is associated with symptomatic and asymptomatic sleep arousals, leading to fragmented sleep. The frequency and influence of acid reflux in patients with various forms of insomnia has not been reported. The aim of this study was to quantify nocturnal acid and nonacid reflux in patients with primary sleep disorders as previously diagnosed by polysomnography. THIRTY ONE SUBJECTS WERE STUDIED: (A) 9 subjects with a polysomnographically diagnosed sleep disorder (1 with restless legs syndrome, 4 with narcolepsy, 4 with periodic limb movement disorder); (B) 12 subjects with primary insomnia (PI) and unrevealing polysomnography; and (C) 10 controls without disturbed sleep. All subjects underwent a physical examination and 24 h transnasal pH and impedance monitoring to detect acid and non-acid reflux. The 21 subjects with fragmented sleep due to a primary sleep disorder had significantly more recumbent acid exposure (>1.2% of time) as compared with control subjects (33% versus 0%). When fragmented sleep subjects were divided into two groups, 17% of PI subjects and 55% of subjects with a diagnosed sleep disorder had significant recumbent acid exposure (P=0.009). Likewise, the median recumbent nonacid events were increased in the sleep disordered group (P=0.011). This study indicates that patients with primary sleep disorders have prominent nocturnal acid reflux without symptoms of daytime acid reflux. Acid reflux is most prominent in patients with polysomnographic findings of disturbed sleep as compared to patients with PI; while non acid reflux is increased minimally in these patients.

    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.

    Gastroesophageal reflux disease (GERD) is prevalent in Asia as well as in Western countries. Sleep disturbance and breathing disorders during sleep are becoming increasingly prevalent, and they are commonly associated with GERD. The relationship between GERD and obstructive sleep apnea (OSA) is still questionable, and it has expanded to include Barrett's esophagus. Nocturnal gastroesophageal reflux (nGER) symptoms might be clinically important in the explanation of this association. The therapy for reflux symptoms has resulted in improved subjective sleep parameters and enhanced sleep quality, thus supporting a direct relationship between GERD and sleep disturbance. This review discusses the epidemiology of sleep disturbances in GERD patients; the causative relationship between GERD and OSA, even though it remains an area of controversy; and the possible role of nGER in sleep problems. It also provides an update on the current state of knowledge linking GERD and sleep. © 2016 New York Academy of Sciences.

    Background Obesity is a risk factor for asthma. Obese asthmatics often have poor asthma control and respond poorly to therapy. It has been suggested that co-morbidities associated with obesity, such as reflux and obstructive sleep apnea, could be important factors contributing to poor asthma control in obese patients. Objectives The purpose of this study was to determine if (i) reflux and/or (ii) symptoms of sleep apnea contribute to poor asthma control in obesity. Methods We studied asthmatic subjects participating in a trial of reflux treatment. Participants underwent baseline evaluation of asthma symptoms and lung function. 304 participants underwent esophageal pH probe testing. 246 participants were evaluated for obstructive sleep apnea symptoms. Results Of 402 participants in this trial, 51% were obese. Role of reflux in asthma control Those with higher body mass index reported a higher prevalence of reflux symptoms, but the prevalence of pH probe acid reflux was similar in all groups. Reflux was not associated with measures of asthma control in obese patients. Role of obstructive sleep apnea in asthma control Symptoms and self-report of obstructive sleep apnea were more common with increasing body mass index and associated with worse asthma control as measured by the Juniper Asthma Control Questionnaire and Asthma Symptom Utility Index. Conclusions Our data suggest that obstructive sleep apnea, but not gastroesophageal reflux disease may contribute significantly to poor asthma control in obese patients. PMID:21819338

    Full Text Available Nonerosive reflux disease (NERD is a distinct pattern of gastroesophageal reflux disease (GERD. It is defined as a subcategory of GERD characterized by troublesome reflux-related symptoms in the absence of esophageal mucosal erosions/breaks at conventional endoscopy. In clinical practice, patients with reflux symptoms and negative endoscopic findings are markedly heterogeneous. The potential explanations for the symptom generation in NERD include microscopic inflammation, visceral hypersensitivity (stress and sleep, and sustained esophageal contractions. The use of 24-hour esophageal impedance and pH monitoring gives further insight into reflux characteristics and symptom association relevant to NERD. The treatment choice of NERD still relies on acid-suppression therapy. Initially, patients can be treated by a proton pump inhibitor (PPI; standard dose, once daily for 2–4 weeks. If initial treatment fails to elicit adequate symptom control, increasing the PPI dose (standard dose PPI twice daily is recommended. In patients with poor response to appropriate PPI treatment, 24-hour esophageal impedance and pH monitoring is indicated to differentiate acid-reflux-related NERD, weakly acid-reflux-related NERD (hypersensitive esophagus, nonacid-reflux-related NERD, and functional heartburn. The response is less effective in NERD as compared with erosive esophagitis.

    Gastroesophageal reflux disease (GERD) is strongly associated with sleep disturbances. Proton pump inhibitor (PPI) therapy improves subjective but not objective sleep parameters in patients with GERD. This study aimed to investigate the association between GERD and sleep, and the effect of PPI on sleep by using a rat model of chronic acid reflux esophagitis. Acid reflux esophagitis was induced by ligating the transitional region between the forestomach and the glandular portion and then wrapping the duodenum near the pylorus. Rats underwent surgery for implantation of electrodes for electroencephalogram and electromyogram recordings, and they were transferred to a soundproof recording chamber. Polygraphic recordings were scored by using 10-s epochs for wake, rapid eye movement sleep, and non-rapid eye movement (NREM) sleep. To examine the role of acid reflux, rats were subcutaneously administered a PPI, omeprazole, at a dose of 20 mg/kg once daily. Rats with reflux esophagitis presented with several erosions, ulcers, and mucosal thickening with basal hyperplasia and marked inflammatory infiltration. The reflux esophagitis group showed a 34.0% increase in wake (232.2±11.4 min and 173.3±7.4 min in the reflux esophagitis and control groups, respectively; preflux esophagitis, and this effect was not observed when the PPI was withdrawn. Acid reflux directly causes sleep disturbances in rats with chronic esophagitis.

    The presence or absence and severity of gastroesophageal reflux before and after intravenous injection of 120 mg Buscopan were evaluated in 112 consecutive patients undergoing upper gastrointestinal examination. The study was undertaken to test the hypothesis that hyoscine butylbromide (Buscopan) could artificially induce gastroesophageal reflux during barium examination of the upper intestinal tract. Gastroesophageal reflux was seen in 49 (44%) of the patients. There was no significant difference in the overall occurrence or degree of gastroesophageal reflux before and after injection of Buscopan. The routine use of Buscopan was therefore unlikely to spuriously increase the frequency or degree of gastroesophageal reflux observed on upper gastrointestinal barium studies. The study also showed that Buscopan had a satisfactory antispasmodic effect and few side effects. 7 refs., 1 tab.

    To determine whether an increased number and duration of non-acid reflux events as measured using the multichannel intraluminal impedance pH (MII-pH) is linked to gastroparesis (GP). A case control study was conducted in which 42 patients undergoing clinical evaluation for continued symptoms of gastroesophageal reflux disease (both typical and atypical symptoms) despite acid suppression therapy. MII-pH technology was used over 24 h to detect reflux episodes and record patients' symptoms. Parameters evaluated in patients with documented GP and controls without GP by scintigraphy included total, upright, and supine number of acid and non-acid reflux episodes (pH 4, respectively), the duration of acid and non-acid reflux in a 24-h period, and the number of reflux episodes lasting longer than 5 min. No statistical difference was seen between the patients with GP and controls with respect to the total number or duration of acid reflux events, total number and duration of non-acid reflux events or the duration of longest reflux episodes. The number of non-acid reflux episodes with a pH > 7 was higher in subjects with GP than in controls. In addition, acid reflux episodes were more prolonged (lasting longer than 5 min) in the GP patients than in controls; however, these values did not reach statistical significance. Thirty-five patients had recorded symptoms during the 24 h study and of the 35 subjects, only 9% (n = 3) had a positive symptom association probability (SAP) for acid/non-acid reflux and 91% had a negative SAP. The evaluation of patients with a documented history of GP did not show an association between GP and more frequent episodes of non-acid reflux based on MII-pH testing.

    The aim of this study was to explore the pathogenesis of chronic cough caused by non-acid reflux. Seven patients with chronic cough due to non-acid reflux, 12 patients with chronic cough due to acid reflux, 10 patients with gastro-oesophageal reflux disease without cough and 12 healthy volunteers were recruited for the study. All subjects underwent oesophageal multi-channel intraluminal impedance measurements combined with pH monitoring, and assessment of cough reflex sensitivity to capsaicin and induced sputum cytology. The concentrations of substance P, mast cell tryptase, prostaglandin D2 and histamine in induced sputum were measured by ELISA. Cough threshold C2 and C5 did not differ between patients with chronic cough due to non-acid or acid reflux, but the values were significantly lower than those for patients with gastro-oesophageal reflux disease without cough and healthy volunteers. Weakly acidic reflux episodes were obviously more frequent in patients with chronic cough due to non-acid reflux than in the other three groups. Sputum substance P and mast cell tryptase concentrations were remarkably increased in patients with chronic cough, but were similar for those with cough due to non-acid or acid reflux. There were significant inverse correlations between substance P levels and cough threshold C2 or C5 in patients with cough due to non-acid or acid reflux, and between mast cell tryptase levels and cough threshold C2 in patients with cough due to acid reflux. Chronic cough due to non-acid reflux may be related to cough reflex hypersensitivity caused by neurogenic airway inflammation and mast cell activation, in which weakly acidic reflux is possibly a major factor. © 2011 The Authors.

    Full Text Available Idiopathic pulmonary fibrosis (IPF is a dreaded disease of uncertain etiology and no available cure. It is still unclear if a causal relationship exists between gastro-esophageal reflux (GER and IPF, but studies have shown an increased prevalence of acid reflux in patients with IPF. We describe a patient with achalasia and GER who went on to develop IPF. She underwent a rapidly worsening course punctuated by acute exacerbations of IPF, despite best efforts to manage the acid GER. We also reviewed the literature on the role of GER in the etiology and progression of IPF and the impact of antireflux measures on its course.

    In a prospective study, 26 patients with symptoms of reflux oesophagitis underwent a barium examination for gastro-oesophageal reflux after food stimulation, and endoscopy with biopsy from different levels of the oesophagus. Radiologic grading of the gastro-oesophageal reflux depending on the height of the reflux into the oesophagus was performed, and this was correlated to the microscopic appearance at different levels in the oesophagus. Complete agreement between the radiologic grading and the histology was found in 69 per cent of the cases, and when gastro-oesophageal reflux was demonstrated the agreement was 75 per cent. Accordingly, the results showed a good accordance between the two variants, indicating that the height of the reflux during the food stimulated test may be truly indicative of the reflux height under non-test conditions.

    Gastroesophageal reflux disease (GERD) is an emerging disease, and can impair quality of life and sleep. This study aimed to investigate whether GERD patients with different timings of reflux symptoms have different clinical characteristics. This study prospectively enrolled individuals who underwent upper gastrointestinal endoscopy during a health checkup. Each participant completed all questionnaires including Reflux Disease Questionnaire, Nighttime GERD questionnaire, Pittsburg Sleep Quality Index, Taiwanese Depression Questionnaire, and State-Trait Anxiety Inventory. Combined reflux was defined as the timing of reflux symptoms occurring at both daytime and nighttime. A total of 2604 participants were enrolled. Of them, 651 symptomatic GERD patients, according to the Reflux Disease Questionnaire score, were recruited for final analysis. Of them, 224 (34.4%) had erosive esophagitis on endoscopy. According to the timing of reflux symptoms, 184 (28.3%) were assigned to the daytime reflux group, 71 (10.9%) to the nighttime reflux group, and 396 (60.8%) to the combined reflux group. In post hoc analysis, the combined reflux group had a significantly higher Reflux Disease Questionnaire score than the daytime reflux group (p reflux groups had higher body mass index and longer duration (> 12 years) of education than the daytime reflux group (p reflux of have more troublesome symptoms than those with daytime reflux. GERD patients with different timings of reflux symptoms have different clinical characteristics in terms of body mass index and duration of education, but not in terms of esophageal inflammation, quality of sleep, and psychosocial status.

    The true prevalence of gastroesophageal reflux disease (GERD) is difficult to establish despite that an estimated 11% of the U.S. population experiencing heartburn daily or 30% every three days (1), perhaps due to that the disease can cause many symptoms, both typical and atypical as heartburn or chest pain, among others. Multiple techniques for measuring reflux have been used, and many authors (1-3) have asked why this situation, possibly because the techniques measure and quantify the basic pathophysiologic problem disease, the time of exposure of the esophagus distal to the gastric juice, because the measures are quantitatively related to the degree of esophageal mucosal injury, or because the episodes of exposure to gastric juice correlated with the patient's symptoms. As said Richter (4) m any times these studies are unnecessary because the history is sufficiently revealing to identify the presence of GERD. But the clinician must decide which test you choose to carry a diagnosis of a reliable, timely and cost-effective . But we cannot rely on the presence of symptoms to diagnosis, because we incur the overdiagnosis in a considerable number of individuals, the sensitivity set for the typical symptoms as heartburn is 68% and specificity was 63% (2), which leads us to conclude that atypical symptoms should be investigated as they may relate to functional dyspepsia rather than GERD. It is also clear that the severity and frequency of symptoms in any way correlates with the presence or absence of esophagitis, patients with erosive esophagitis are more severe disease and increased risk of developing complications. The persistent exposure of the esophagus to gastric juice does not cause mucosal injury in all individuals, therefore, it is possible to define the disease by the presence of mucosal injury, while endoscopy is able to define the mucosal injury caused by the reflux can also lead to false conclusions, such as those patients with symptoms of GERD who have no

    Full Text Available The increasing prevalence of gastroesophageal reflux disease (GERD in children and adults, and of “silent refluxers” in particular, increases the responsibility of dentists to be alert to this potentially severe condition when observing unexplained instances of tooth erosion. Although gastroesophageal reflux is a normal physiologic occurrence, excessive gastric and duodenal regurgitation combined with a decrease in normal protective mechanisms, including an adequate production of saliva, may result in many esophageal and extraesophageal adverse conditions. Sleep-related GERD is particularly insidious as the supine position enhances the proximal migration of gastric contents, and normal saliva production is much reduced. Gastric acid will displace saliva easily from tooth surfaces, and proteolytic pepsin will remove protective dental pellicle. Though increasing evidence of associations between GERD and tooth erosion has been shown in both animal and human studies, relatively few clinical studies have been carried out under controlled trial conditions. Suspicion of an endogenous source of acid being associated with observed tooth erosion requires medical referral and management of the patient as the primary method for its prevention and control.

    Gastro-oesophageal reflux disease (GORD) is on the rise with more than 20% of the western population reporting symptoms and is the most common gastrointestinal disorder in the United States. This increase in GORD is not exactly clear but has been attributed to the increasing prevalence of obesity, changing diet, and perhaps the decreasing prevalence of H. pylori infection. Complications of GORD could be either benign or malignant. Benign complications include erosive oesophagitis, bleeding and peptic strictures. Premalignant and malignant lesions include Barrett's metaplasia, and oesophageal cancer. Management of both the benign and malignant complications can be challenging. With the use of proton-pump inhibitors, peptic strictures (i.e., strictures related to reflux) have significantly declined. Several aspects of Barrett's management remain controversial including the stage in the disease process which needs to be intervened, type of the intervention and surveillance of these lesions to prevent development of high grade dysplasia and oesophageal adenocarcinoma.

    In a prospective study a barium examination combined with food stimulation was compared with the acid reflux test in 30 consecutive patients with symptoms of gastro-oesophageal reflux. Both methods were further compared with endoscopy and histology. Gastro-oesophageal reflux could be demonstrated by the radiologic examination in 22 patients and by the acid reflux test in 23 patients. By combining the two methods gastro-oesophageal reflux could be demonstrated in 27 patients. Comparing the two methods with symptoms, endoscopy, and histology they seemed to be of equal value. Accordingly, a food-stimulated barium examination is recommended as the first method for demonstrating gastro-oesophageal reflux because it is simple and well-tolerated by the patient. (orig.)

    Ethnic and geographical differences are important factors in studying disease frequencies, because they may highlight the environmental or genetic influences in the etiology. We retrieved the studies which have been published regarding the epidemiologic features of gastroesophageal reflux disease (GERD) in Asia, based on the definitions of GERD, study settings, publication years and geographical regions. From the population-based studies, the prevalence of symptom-based GERD in Eastern Asia was found to be 2.5%-4.8% before 2005 and 5.2%-8.5% from 2005 to 2010. In Southeast and Western Asia, it was 6.3%-18.3% after 2005, which was much higher than those in Eastern Asia. There were robust epidemiologic data of endoscopic reflux esophagitis in medical check-up participants. The prevalence of endoscopic reflux esophagitis in Eastern Asia increased from 3.4%-5.0% before 2000, to 4.3%-15.7% after 2005. Although there were only limited studies, the prevalence of extra-esophageal syndromes in Asia was higher in GERD group than in controls. The prevalence of Barrett's esophagus was 0.06%-0.84% in the health check-up participants, whereas it was 0.31%-2.00% in the referral hospital settings. In summary, the prevalence of symptom-based GERD and endoscopic reflux esophagitis has increased in Asian countries. However, the prevalence of Barrett's esophagus in Asia has not changed and also still rare. PMID:21369488

    The costs of gastroesophageal reflux disease have not been assessed in Asia, even though the prevalence of gastroesophageal reflux disease is gradually increasing. We evaluated work presenteeism and absenteeism as indirect costs of gastroesophageal reflux disease in Korea. This was a cross-sectional and multicentre study using patient-reported outcome instruments. A total of 1009 full-time employees who visited the gastrointestinal department for any reason (281 patients with gastroesophageal reflux disease and 728 controls) were included. Main outcomes were presenteeism and absenteeism measured as work productivity loss and monetary cost per week. Absenteeism and presenteeism were significantly higher in the gastroesophageal reflux disease than the control group (1.49% vs. 0.46%, P=0.0010; 34.13% vs. 9.23%, Pgastroesophageal reflux disease than the control group (33.09% vs. 9.02%; Pgastroesophageal reflux disease group compared with the control group. Assuming average hourly wages of $14.12, the weekly burden of gastroesophageal reflux disease reached $165.07 per person. Gastroesophageal reflux disease was associated with substantial work productivity loss, mainly due to presenteeism rather than absenteeism, in Korean full-time employees.

    Full Text Available Background: Gastro-oesophageal reflux may accompany the corrosive oesophageal damage caused by the ingestion of corrosive substances and affect its treatment. The factors that affect the development of reflux in these cases and their effects on treatment still remain unclear. Aims: Our aim is to investigate the prevalence of gastro-oesophageal reflux in children with corrosive oesophageal strictures, the risk factors affecting this prevalence and the effects of gastro-oesophageal reflux on treatment. Study Design: Case-control study. Methods: We enrolled 52 patients with oesophageal stricture due to corrosive substance ingestion who were referred to our clinic between 2003 and 2010. Groups, which were determined according to the presence of gastro-oesophageal reflux (GER, were compared with each other in terms of clinical findings, results of examination methods, characteristics of the stricture and success of the treatment. Results: The total number of patients in our study was 52; 30 of them were male and 22 of them were female. The mean age of our study population was 4.2±2.88 years. Thirty-three patients had gastro-oesophageal reflux (63.5%. Patients who had strictures caused by the ingestion of alkali substances were 1.6-times more likely to have reflux. There were no differences between patients with or without reflux in terms of number and localisation of strictures. Mean distance of stricture was longer in patients with reflux (3.7±1.8 cm than in patients without (2.2±1.0 cm (p0.05. Conclusion: Corrosive oesophageal stricture was usually accompanied by gastro-oesophageal reflux and the length of stricture is an important risk factor. Negative effects of reflux over dilatation treatment have not yet been demonstrated in the short-term. Nevertheless, this frequent rate of reflux may eventually increase the risk of oesophagitis and Barrett’s oesophagus; therefore, we suggest that these effects should be prospectively evaluated in a

    AIM: To clarify the pathogenesis of gastroesophageal reflux disease symptoms in non-erosive reflux disease (NERD) patients. METHODS: Thirty-five NERD patients with persistent symptoms, despite taking rabeprazole 10 mg twice daily for at least 8 wk, were included in this study. All patients underwent 24 h combined impedance - pH on rabeprazole. The symptom index (SI) was considered to be positive if ≥ 50%, and proximal reflux episodes were determined when reflux reached 15 cm above the proximal margin of the lower esophageal sphincter. RESULTS: In 14 (40%) SI-positive patients, with liquid weakly acid reflux, the occurrence rate of reflux symptoms was significantly more frequent in proximal reflux episodes (46.7%) than in distal ones (5.7%) (P acid reflux, there were no significant differences in the occurrence rate of reflux symptoms between proximal reflux episodes (38.5%) and distal ones (20.5%) (NS). With mixed liquid-gas weakly acid reflux, the occurrence rate of reflux symptoms in proximal reflux episodes was significantly more frequent (31.0%) than in distal reflux ones (3.3%) (P acid reflux, there were no significant differences in the occurrence rate of reflux symptoms between proximal reflux episodes (29.4%) and distal ones (14.3%) (NS). CONCLUSION: The proximal extent of weakly acidic liquid and mixed liquid-gas reflux is a major factor associated with reflux perception in SI-positive patients on proton pump inhibitor therapy.

    Sixty-five symptomatic infants and children underwent radionuclide gastroesophagography, acid reflux testing, and barium esophagography with water-siphon testing to evaluate the clinical efficacy of the scintigraphic technique in detecting gastroesophageal reflux. After ingesting /sup 99m/Tc sulfur colloid in fruit juice, patients rested beneath the gamma camera for 30 to 60 min while esophageal activity was monitored continuously. By using the acid reflux test as a standard of comparison, the senstivity of radionuclide gastroesophagography was 75%. Because of its physiologic nature, low radiation exposure, and convenience, radionuclide gastroesophagography warrants further evaluation as a screening test for gastroesophageal reflux

Proton pump inhibitor (PPI therapy improves subjective but not objective sleep parameters in patients with GERD. This study aimed to investigate the association between GERD and sleep, and the effect of PPI on sleep by using a rat model of chronic acid reflux esophagitis. METHODS: Acid reflux esophagitis was induced by ligating the transitional region between the forestomach and the glandular portion and then wrapping the duodenum near the pylorus. Rats underwent surgery for implantation of electrodes for electroencephalogram and electromyogram recordings, and they were transferred to a soundproof recording chamber. Polygraphic recordings were scored by using 10-s epochs for wake, rapid eye movement sleep, and non-rapid eye movement (NREM sleep. To examine the role of acid reflux, rats were subcutaneously administered a PPI, omeprazole, at a dose of 20 mg/kg once daily. RESULTS: Rats with reflux esophagitis presented with several erosions, ulcers, and mucosal thickening with basal hyperplasia and marked inflammatory infiltration. The reflux esophagitis group showed a 34.0% increase in wake (232.2±11.4 min and 173.3±7.4 min in the reflux esophagitis and control groups, respectively; p<0.01 accompanied by a reduction in NREM sleep during light period, an increase in sleep fragmentation, and more frequent stage transitions. The use of omeprazole significantly improved sleep disturbances caused by reflux esophagitis, and this effect was not observed when the PPI was withdrawn. CONCLUSIONS: Acid reflux directly causes sleep disturbances in rats with chronic esophagitis.

    Vesicoureteral reflux (VUR) remains the most interesting topic of pediatric urology due to the dynamic nature of recent controversial publications. Starting from the need for a diagnosis to the necessity and effectiveness of treatment in preventing scars, VUR remains in the mist. Although recent strong evidence helped as fog lights in this blurriness, more data are required for achieving crystal clearance. This article aims to summarize and discuss the current state of the evidence regarding VUR management. To provide a comprehensive synthesis of the main evidence in the literature on the current and contemporary management of VUR in children; to discuss conservative management with continuous antibiotic prophylaxis (CAP), especially its effectiveness and safety; and to review the current evidence regarding contemporary surgical techniques. We conducted a nonsystematic review of the literature using the recent guidelines and PubMed database regarding surveillance, CAP, endoscopic, open, laparoscopic, and robot-assisted ureteral surgical treatment. Despite the striking results of previous studies revealing the ineffectiveness of CAP, more recent studies and their two fresh meta-analyses revealed a positive role for CAP in the contemporary management of VUR. One of the most interesting findings is the redundant rising of endoscopic correction and its final settlement to real indicated cases. Patient individualization in the contemporary management of VUR seems to be the keyword. The evidence in the literature showed a safe and effective use of laparoscopic and robot-assisted laparoscopic reimplantations. The goal of VUR treatment is to prevent the occurrence of febrile urinary tract infections and formation of scars in the renal parenchyma. The approach should be risk adapted and individualized according to current knowledge. Individual risk is influenced by the presentation age, sex, history of pyelonephritis and renal damage, grade of reflux, bladder bowel

    The nadir esophageal pH of reflux observed during pH monitoring in the postprandial period is often more acidic than the concomitant intragastric pH. This paradox prompted the discovery of the "acid pocket", an area of unbuffered gastric acid that accumulates in the proximal stomach after meals and serves as the reservoir for acid reflux in healthy individuals and gastroesophageal reflux disease (GERD) patients. However, there are differentiating features between these populations in the size and position of the acid pocket, with GERD patients predisposed to upward migration of the proximal margin onto the esophageal mucosa, particularly when supine. This upward migration of acid, sometimes referred to as an "acid film", likely contributes to mucosal pathology in the region of the squamocolumnar junction. Furthermore, movement of the acid pocket itself to a supradiaphragmatic location with hiatus hernia increases the propensity for acid reflux by all conventional mechanisms. Consequently, the acid pocket is an attractive target for GERD therapy. It may be targeted in a global way with proton pump inhibitors that attenuate acid pocket development, or with alginate/antacid combinations that colocalize with the acid pocket and displace it distally, thereby demonstrating the potential for selective targeting of the acid pocket in GERD.

    Full Text Available Many GPs are increasingly dealing with patients complaining of ailments likely to suggest gastro-esophageal reflux disease (GERD. These symptoms include heartburn, abdominal pain, and a feeling of esophageal reflux (regurgitation. GERD is one of the most common gastrointestinal diseases that gastroenterologists meet in their practice (1, 2. In North America the problem is affected from 18.1% to even 27.8% of the population. The situation is similar in Europe, where the proportion of people with reflux symptoms is in the range of 8.8% - 25.9%. Among European countries, the prevalence of GERD symptoms is higher in the north of the continent than in the south. The growing problem of overweight and obesity that makes GERD more and more recognized in the population of children and adolescents (3 is a worrying fact. Interestingly, reflux-related complaints are much less frequent in eastern Asia, affecting only 2.5% -7.8% of the population (4.

    Radionucleotide scintigraphy and esophagoscopy with biopsy were carried out in 101 patients with symptoms strongly suggestive of gastroesophageal reflux (GER) disease. GER was visualized by scintigraphy in 86.1% of the patients. Endoscopic and histologic esophagitis were found in 68.1% and 58.4% of the patients, respectively, whereas both examinations taken together showed evidence of esophagitis in 82%. Histologic evidence of esophagitis was found in nearly all patients with severe endoscopic changes, and in 43.7% of the patients with no endoscopic abnormality. Scintigraphic reflux was demonstrated more frequently in the patients with severe endoscopic esophagitis (97.5%) than in those with no or only mild endoscopic changes (78.6%). Scintigraphic reflux was found in 91.5% and 78.5% of the patients with and without histologic evidence of esophagitis. 15 of the 18 patients (83.3%) without endoscopic and histologic abnormalities in the esophagus had scintigraphic evidence of reflux. The present study strongly supports the clinical significance of scintigraphy in GER disease and confirms that esophageal biopsy specimens increase the sensitivity of endoscopic evaluation. 31 refs.

    The mechanisms that cause acid reflux in patients with non-erosive reflux disease (NERD), including those that determine how acid extends proximally, are not yet clear. Concurrent esophageal manometry and pH monitoring were performed for 3 h after a meal in 13 patients with NERD, 12 with mild reflux esophagitis (RE), and 13 healthy subjects (HS). Transient lower esophageal sphincter (LES) relaxation (TLESR) was the major mechanism of acid reflux in all three groups. LES pressure did not differ between the groups. At 2 cm above the LES, there were no differences between the three groups in the number of TLESR-related acid reflux episodes, rate of TLESRs and rate of acid reflux during TLESR. However, at 7 cm above the LES, the rate of acid reflux during TLESRs was significantly higher in patients with NERD (mean ± SEM 42.3 ± 4.8) than in those with mild RE (28.0 ± 3.8) and HS (10.8 ± 2.5). TLESRs are the sole motor events underlying acid reflux episodes in patients with NERD. Acid extends proximally more readily in patients with NERD than in HS and those with mild RE.

    Patients with deflation cough (DC), the cough-like expulsive effort(s) evoked by maximal lung emptying during a slow vital capacity maneuver, also present symptoms of gastroesophageal reflux. DC can be inhibited by prior intake of antacids. We wished to assess DC prevalence and association between DC and chemical characteristics of refluxate in patients with gastroesophageal reflux symptoms. A total of 157 consecutive outpatients underwent DC assessment and 24-h multichannel intraluminal impedance pH (MII-pH) monitoring; 93/157 also had chronic cough. Patients performed two to four slow vital capacity maneuvers and DC was detected aurally. Subsequently, they underwent 24-h MII-pH monitoring, the outcomes of which were defined as abnormal when acid or non-acid reflux events were > 73. DC occurred in 46/157 patients, 18 of whom had abnormal MII-pH outcomes; 28 of the remaining 111 patients without DC also had abnormal MII-pH findings. Thus, in the patients as a group, there was no association between DC and MII-pH outcomes. DC occurred in 40/93 of the chronic coughers; 15 of whom had acid reflux. All but 2 of the 53 patients without DC had normal MII-pH outcomes (P < .001), and the negative predictive value of DC for excluding acid reflux was 96.2%. At follow-up, 65% of coughers showed significant improvement after treatment. The overall prevalence of DC was 29%, increasing to 43% in chronic coughers in whom the absence of DC virtually excludes acid reflux. Therefore, DC assessment may represent a useful screening test for excluding acid reflux in chronic coughers with reflux symptoms. Copyright © 2016 American College of Chest Physicians.

    There is a general belief that gastro-oesophageal reflux increases after meals and especially following a rapid intake. To evaluate the impact of rapid vs. slow food intake on gastro-oesophageal reflux disease (GORD) patients. Forty-six GORD patients with heartburn and / or acid regurgitation once a week or more often common were included in this study. Participants were asked to eat the same standard meal within either 5 or 30 minutes under observation in a random order on 2 consecutive days. A total of 28 hours of recording were obtained by intraoesophageal impedance pH and number of liquid and mixed reflux episodes within 3 hours of the slow- and fast-eating postprandial periods were calculated. While all patients defined GORD symptoms, 10 (21.7%) had pathological 24-h intraoesophageal impedance measurement, 15 (32.6%) had pathological DeMeester and 21.7% had erosive oesophagitis. No difference has been shown according to the eating speed when all reflux episodes were taken together (754 vs. 733). Speed of food intake also did not have an impact on patients with normal vs. pathological 24-h intraoesophageal impedance or erosive vs. non-erosive. During the first postprandial hour, approximately half of the reflux events were non-acid, compared to 34.2% during the second hour and 26.8% during the third hour (p reflux episodes was significantly higher than non-acid reflux especially during the second and third hours and in total for 3 hours. This first study addressing the effect of eating speed on reflux episodes in GORD patients did not support the general belief that reflux increases following fast eating. Acid and non-acid reflux were similar at the first postprandial hour, then acid reflux episodes were predominantly higher, which implicate the importance of acid pockets.

    To investigate the association between esophageal motility and acid reflux in patients with gastroesophageal reflux disease (GERD). A total of 94 patients with typical reflux symptoms such as heartburn, regurgitation and chest pain, whose score (Sc) of reflux diagnostic questionnaire (RDQ) was greater than or equal to 12 were enrolled in the study. Each participant was evaluated by upper gastrointestinal endoscopy, high resolution manometry (HRM) of esophagus and 24 h esophageal pH monitoring. The participants were divided into groups of reflux esophagitis (RE) and non-erosive reflux disease (NERD) on the basis of endoscopy findings. The 24 h esophageal pH monitoring categorized participants into physiologic reflux (pH) and pathologic reflux (pH+). The characteristics of esophageal motility and acid reflux were compared between the two groups of participants. Lower but non-significant differences (P > 0.05) were found in pressure of lower esophageal sphincter (LESP), length of lower esophageal sphincter (LESL), esophageal contraction amplitude (CA), distal contractile integral (DCI) and effective peristalsis proportion (EPP) in the participants in the RE group compared with those in the NERD group. Participants in the RE group had significantly higher prevalence of reduced LESP (63.0% vs. 31.7%, P 0.05). RE is closely associated with acid reflux and hiatus hernia. Esophageal dysmotility is more likely to appear in patients with pH+. The interaction of acid reflux and esophageal dysmotility may play a role in GERD.

  5. Nasogastric intubation causes gastroesophageal reflux in patients undergoing elective laparotomy.

    BACKGROUND: The routine use of nasogastric tubes in patients undergoing elective abdominal operation is associated with an increased incidence of postoperative fever, atelectasis, and pneumonia. Previous studies have shown that nasogastric tubes have no significant effect on the incidence of gastroesophageal reflux or on lower esophageal sphincter pressure in healthy volunteers. We hypothesized that nasogastric intubation in patients undergoing laparotomy reduces lower esophageal sphincter pressure and promotes gastroesophageal reflux in the perioperative period. METHODS: A prospective randomized case-control study was undertaken in which 15 consenting patients, admitted electively for bowel surgery, were randomized into 2 groups. Group 1 underwent nasogastric intubation after induction of anesthesia, and Group 2 did not. All patients had manometry and pH probes placed with the aid of endoscopic vision at the lower esophageal sphincter and distal esophagus, respectively. Nasogastric tubes, where present, were left on free drainage, and sphincter pressures and pH were recorded continuously during a 24-hour period. Data were analyzed with 1-way analysis of variance. RESULTS: The mean number of reflux episodes (defined as pH < 4) in the nasogastric tube group was 137 compared with a median of 8 episodes in the group managed without nasogastric tubes (P =.006). The median duration of the longest episode of reflux was 132 minutes in Group 1 and 1 minute in Group 2 (P =.001). A mean of 13.3 episodes of reflux lasted longer than 5 minutes in Group 1, with pH less than 4 for 37.4% of the 24 hours. This was in contrast to Group 2 where a mean of 0.13 episodes lasted longer than 5 minutes (P =.001) and pH less than 4 for 0.2% of total time (P =.001). The mean lower esophageal sphincter pressures were lower in Group 1. CONCLUSIONS. These findings demonstrate that patients undergoing elective laparotomy with routine nasogastric tube placement have significant gastroesophageal

    Chronic cough affects more than 70 percent of patients with Idiopathic Pulmonary Fibrosis and causes significant morbidity. Gastroesophageal reflux is the cause of some cases of chronic cough; and also has a postulated role in the aetiology of Idiopathic Pulmonary Fibrosis. A high prevalence of acid; and more recently non-acid, reflux has been observed in Idiopathic Pulmonary Fibrosis cohorts. Therefore, gastroesophageal reflux may be implicated in the pathogenesis of cough in Idiopathic Pulmonary Fibrosis. Eighteen subjects with Idiopathic Pulmonary Fibrosis underwent 24-hour oesophageal impedance and cough count monitoring after the careful exclusion of causes of chronic cough other than gastroesophageal reflux. All 18 were then treated with high dose acid suppression therapies. Fourteen subjects underwent repeat 24-hour oesophageal impedance and cough count monitoring after eight weeks. Total reflux and acid reflux frequencies were within the normal range in the majority of this cohort. The frequencies of non-acid and proximal reflux events were above the normal range. Following high dose acid suppression therapy there was a significant decrease in the number of acid reflux events (p = 0.02), but an increase in the number of non-acid reflux events (p = 0.01). There was no change in cough frequency (p = 0.70). This study confirms that non-acid reflux is prevalent; and that proximal oesophageal reflux occurs in the majority, of subjects with Idiopathic Pulmonary Fibrosis. It is the first study to investigate the effect of acid suppression therapy on gastroesophageal reflux and cough in patients with Idiopathic Pulmonary Fibrosis. The observation that cough frequency does not improve despite verifiable reductions in oesophageal acid exposure challenges the role of acid reflux in Idiopathic Pulmonary Fibrosis associated cough. The finding that non-acid reflux is increased following the use of acid suppression therapies cautions against the widespread use

    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. Copyright © 2016 Elsevier Ltd.

    2011-01-01

    Background/Aims Impedance-pH monitoring allows detailed characterization of gastroesophageal reflux and esophageal activity associated with reflux. We assessed the characteristics of nocturnal reflux and esophageal activity preceding and following reflux. Methods Impedance-pH tracings from 11 healthy subjects and 76 patients with gastroesophageal reflux disease off acid-suppressive therapy were analyzed. Characteristics of nocturnal supine reflux, time distribution and esophageal activity seen on impedance at 2 minute intervals preceding and following reflux were described. Results Patients had more nocturnal reflux events than healthy subjects (8 [4-12] vs 2 [1-5], P = 0.002), with lower proportion of weakly acidic reflux (57% [35-78] vs 80% [60-100], P = 0.044). Nocturnal reflux was mainly liquid (80%) and reached the proximal esophagus more often in patients (6% vs 0%, P = 0.047). Acid reflux predominated in the first 2 hours (66%) and weakly acidic reflux in the last 3 hours (70%) of the night. Most nocturnal reflux was preceded by aboral flows and cleared by short lasting volume clearance. In patients, prolonged chemical clearance was associated with less esophageal activity. Conclusions Nocturnal weakly acidic reflux is as common as acid reflux in patients with gastroesophageal reflux disease, and predominates later in the night. Impedance-pH can predict prolonged chemical clearance after nocturnal acid reflux. PMID:21602991

    During radionuclide scans in 82 infants and children gastro-oesophageal reflux extending to the upper oesophageal/laryngeal level was detected in 636 one minute frames. Only 61 (9.6%) of these frames were associated with vomiting, defined as the appearance of milk at the mouth. Thus the absence of vomiting does not preclude appreciable gastro-oesophageal reflux.

    Background Dental erosion is a complication of gastro-oesophageal reflux disease (GORD) according to the Montreal consensus statement. However, GORD has not been comprehensively characterized in patients with dental erosions and pH-impedance measures have not been reported. Objectives Characterize GORD in patients with dental erosions using 24-h multichannel intraluminal pH-impedance measurements (pH-MII) and endoscopy. Methods This single-centre study investigated reflux in successive patients presenting to dentists with dental erosion using pH-MII and endoscopy. Results Of the 374 patients, 298 (80%) reported GORD symptoms reflux episodes were 71 (63–79), 43 (38–49) and 31 (26–35), respectively. Of the reflux episodes, 19% (17–21) reached the proximal oesophagus. In 241 (69%) patients reflux was abnormal using published normal values for acid exposure time and reflux episodes. No significant associations between the severity of dental erosions and any reflux variables were found. The presence of GORD symptoms and of oesophagitis or a hiatal hernia was associated with greater reflux, but not with increased dental erosion scores. Conclusions Significant oligosymptomatic gastro-oesophageal reflux occurs in the majority of patients with dental erosion. The degree of dental erosion did not correlate with any of the accepted quantitative reflux indicators. Definition of clinically relevant reflux parameters by pH-MII for dental erosion and of treatment guidelines are outstanding. Gastroenterologists and dentists need to be aware of the widely prevalent association between dental erosion and atypical GORD. PMID:25922678

    Gastroesophageal reflux (GER) and aspiration of bile acids have been implicated as non-alloimmune risk factors for the development of bronchiolitis obliterans syndrome (BOS) after lung transplantation. The aim of our study was to investigate the association between GER and gastric aspiration of bile acids and to establish which reflux characteristics may promote aspiration of bile acids into the lungs and may feature as a potential diagnostic tool in identifying lung transplantation (LTx) patients at risk for aspiration. Twenty-four stable LTx recipients were studied 1 year after transplantation. All patients underwent 24-hour ambulatory impedance-pH recording for the detection of acid (pH acidic (pH 4 to 7) reflux. On the same day, bronchoalveolar lavage fluid (BALF) was collected and then analyzed for the presence of bile acids (Bioquant enzymatic assay). Increased GER was detected in 13 patients, of whom 9 had increased acid reflux and 4 had exclusively increased weakly acidic reflux. Sixteen patients had detectable bile acids in the BALF (0.6 [0.4 to 1.5] micromol/liter). The 24-hour esophageal volume exposure was significantly increased in patients with bile acids compared to patients without bile acids in the BALF. Acid exposure and the number of reflux events (total, acid and weakly acidic) were unrelated to the presence of bile acids in the BALF. However, both nocturnal volume exposure and the number of nocturnal weakly acidic reflux events were significantly higher in patients with bile acids in the BALF. Weakly acidic reflux events, especially during the night, are associated with the aspiration of bile acids in LTx recipients and may therefore feature as a potential risk factor for the development of BOS.

    Five patients initially presenting with symptomatic gastro-oesophageal reflux, proven by radiology or pH monitoring, subsequently developed achalasia, confirmed by radiology and manometry, after an interval of 2-10 years. During this period dysphagia, present as a mild and intermittent symptom accompanying the initial reflux in 3 of the 5, became severe and resulted in oesophageal stasis of food in all. Three of the 5 had a demonstrable hiatal hernia. In none was reflux a troublesome symptom after Rider-Moeller dilatation or cardiomyotomy undertaken for the achalasia. Gastro-oesophageal reflux does not protect against the subsequent development of achalasia. It is suggested that the autonomic damage eventually leading to achalasia may in its initial phases cause gastro-oesophageal reflux. Images Figure 1. A Figure 1. B Figure 2. PMID:3950898

    Fluoroscopic esophagography is a widely available, safe, and inexpensive test for detecting gastroesophageal reflux disease. In this article, we review the technique for performing a high-quality esophagram, including upright, double-contrast views of the esophagus and cardia with high-density barium; prone, single-contrast views of the esophagus with low-density barium; and evaluation of gastroesophageal reflux. We then discuss the radiographic findings associated with gastroesophageal reflux disease, including esophageal dysmotility, reflux esophagitis, peptic strictures, and Barrett's esophagus. Finally, we consider the differential diagnosis for the various radiographic findings associated with this condition. When carefully performed and interpreted, the esophagram is a useful test for evaluating gastroesophageal reflux disease and its complications.

  16. Reflux Revisited: Advancing the Role of Pepsin

    Directory of Open Access Journals (Sweden)

    Karna Dev Bardhan

    2012-01-01

    Full Text Available Gastroesophageal reflux disease is mediated principally by acid. Today, we recognise reflux reaches beyond the esophagus, where pepsin, not acid, causes damage. Extraesophageal reflux occurs both as liquid and probably aerosol, the latter with a further reach. Pepsin is stable up to pH 7 and regains activity after reacidification. The enzyme adheres to laryngeal cells, depletes its defences, and causes further damage internally after its endocytosis. Extraesophageal reflux can today be detected by recognising pharyngeal acidification using a miniaturised pH probe and by the identification of pepsin in saliva and in exhaled breath condensate by a rapid, sensitive, and specific immunoassay. Proton pump inhibitors do not help the majority with extraesophageal reflux but specifically formulated alginates, which sieve pepsin, give benefit. These new insights may lead to the development of novel drugs that dramatically reduce pepsinogen secretion, block the effects of adherent pepsin, and give corresponding clinical benefit.

    Otolaryngological manifestations of acid reflux include a wide range of pharyngeal and laryngeal symptoms; and the constellation of symptoms has been called laryngopharyngeal reflux. This is a prospective study in a cohort of patients with various throat symptoms suggestive of laryngopharyngeal reflux (LPR) who underwent flexible oesophago-gastroscopy, as a principal investigation. The aims were to look at the most reliable symptom(s) and sign(s), the diagnostic role of flexible oesophago-gastroscopy and the treatment response in these patients. The endoscopy score of 0 to 3 was based on endoscopic findings and the treatment response was measured from 0 to 100 per cent improvement of symptoms, as described by the patients. There were a total of 303 patients, 174 females and 129 males with ages ranging from 19 to 88 years. Seventy-five per cent had had symptoms for more than a year. Fifteen per cent were smokers. Globus, voice change, sore throat, dysphagia and cough were the predominant symptoms. Most patients, however, presented with a complex of various other secondary symptoms. The endoscopic findings were abnormal in 98 per cent of patients. Apart from the finding of non-specific hyperaemia, usually of the posterior larynx (13 per cent), lesions of the larynx and vocal folds were surprisingly uncommon. Proton pump inhibitors (PPI) were prescribed in 90 per cent of patients. A total of 233 (76.8 per cent) responded to treatment. The improvement of symptoms ranged from 25 per cent in 36 (23 per cent), 50 per cent in 60 (20 per cent), 75 per cent in 59 (19 per cent) and 100 per cent in 78 (26 per cent) patients. Accumulative analysis of variance showed a significant difference between treatment responders and non-responders (p <0.04). In a logistic regression model patients with globus, voice change and gastric prolapse were more likely to respond to treatment (p <0.04).

    Current imaging modalities such as magnetic resonance imaging and computed tomography provide anatomic resolution far beyond that achievable with the current methods of scintigraphic imaging. Consequently, the strength of nuclear medicine has shifted and now lies in its ability to provide physiologic data noninvasively and simply. This ability is well illustrated by the scintigraphic techniques developed for evaluation of the alimentary tract. Studies of esophageal transit, gastroesophageal reflux, and gastric emptying are now widely available. Evaluation of small and large intestinal transit have also been investigated. These techniques are discussed in the present chapter

    Gastroesophageal reflux (GER) may be defined as a dysfunction of the distal esophagus causing return of gastric contents into the esophagus. GER is a rather common problem during infancy, with an incidence estimated as 1 in 500 infants. Several methods are available to diagnose and quantitate GER. These include fluoroscopy after barium feedings, in conjunction with an upper gastrointestinal series; esophageal manometry; endoscopy; pH probe monitoring, in conjunction with a Tuttle Test; and extended pH probe evaluation for a 24-h period. Gastroesophageal scintigraphy has been advocated as an alternative noninvasive study requiring no sedation. Scintigraphy offers the advantages of prolonged observation, high sensitivity, and low radiation exposure

    We tested the hypothesis that gastro-esophageal reflux disease is a risk factor for exacerbations in individuals with chronic obstructive pulmonary disease (COPD). Among 9622 participants in the Copenhagen City Heart Study, we identified 1259 individuals with COPD and information on gastro-esophageal reflux disease and the regular use of acid inhibitory treatment. These individuals were followed for 5 years with regard to medically treated COPD exacerbations, which we defined as a short course treatment with oral corticosteroids alone or in combination with antibiotics. We applied a multivariable Cox regression analysis with adjustment for well-established risk factors associated with COPD exacerbations or gastro-esophageal reflux disease, including COPD severity, and symptoms. Individuals with COPD and gastro-esophageal reflux disease had more chronic bronchitis (31 vs 21%, P = 0.004), more breathlessness (39 vs 22%, P gastro-esophageal reflux disease. Among individuals with COPD and gastro-esophageal reflux disease, those who did not use acid inhibitory treatment regularly had an increased risk of COPD exacerbations during follow-up, hazards ratio (HR): HR = 2.7 (1.3-5.4, P = 0.006). Individuals with gastro-esophageal reflux disease, using acid inhibitory treatment regularly did not have an increased risk of exacerbations, HR = 1.2 (0.6-2.7, P = 0.63). Gastro-esophageal reflux disease was associated with an increased risk of medically treated exacerbations of COPD, but only in those individuals who did not use acid inhibitory treatment regularly. © 2014 Asian Pacific Society of Respirology.

    The intrarenal reflux plays the key role in the etiology of reflux nephropathy and its detection is of utmost importance in evaluating possible damage in kidney with reflux. In 176 kidneys (113 children) with different degree of vesicoureteric reflux (VUR), dynamic renal scintigraphy with Tc-99m-DTPA in zoom mode was performed. From each study 6 functional images of mean time were generated, kidney contour superimposed on each, and time activity curves (TAC) over possible areas of increased mean time were generated. In these study we analyzed only areas of increased mean time over the outer contour of the kidney which corresponds to the renal parenchyma. In later functional images of the mean time we found 53 focal retentions over the part of the kidney which corresponds to the renal cortex (33 in upper, 5 in middle and 15 in lower part of the kidney). TAC-s generated over these areas exhibited a sharp increase of activity on the descending part of the curves. We propose that the return of activity from the collecting system to the kidney cortex represents intrarenal reflux. In our opinion, analysis of functional images of the mean time could be a method for more accurate detection of intrarenal reflux and indicating the children with high risk to acquire renal scarring.

    Non-specific esophageal dysmotility with impaired clearance is often present in patients with gastro-esophageal reflux disease (GERD), especially those with erosive disease; however the physio-mechanic basis of esophageal dysfunction is not well defined. Retrospective assessment of patients with erosive reflux disease (ERD; n=20) and endoscopy negative reflux disease (ENRD; n=20) with pathologic acid exposure on pH studies (>4.2% time/24 h) and also healthy controls (n=20) studied by high resolution manometry. Esophageal motility in response to liquid and solid bolus swallows and multiple water swallows (MWS) was analyzed. Peristaltic dysfunction was defined as failed peristalsis, spasm, weak or poorly coordinated esophageal contraction (>3cm break in 30 mmHg isocontour). Peristaltic dysfunction was present in 33% of water swallows in controls, 56% ENRD and 76% ERD respectively (Preflux events and increase exposure to gastric refluxate. © 2011 Blackwell Publishing Ltd.

    Vesicoureteral reflux (VUR) is frequently found after transplantation, but its impact on graft function, urine tract infection, and graft loss remains uncertain. Therefore our objective was to evaluate the effects of VUR on the outcome of renal transplantation. We included 1008 adult renal transplant recipients of whom a 1-week posttransplant voiding cystourethrogram was available. Study end points included occurrence of bacteriuria, renal function, and graft survival. In total, 106 (10.5%) of 1008 graft recipients had a diagnosis of VUR on voiding cystography. The incidence of bacteriuria was comparable in the reflux and nonreflux group (17% vs 17.4%, P = .91). There was no significant difference in renal function at 3 months and 1 year in patients with and without VUR. One- and 5-year graft survival in patients with VUR was 85.8% and 82.1% compared to 87.3% and 83.0% in patients without VUR ( P = .68 and P = .80). Posttransplant VUR has no correlations with early bacteriuria, renal function, and graft survival.

    Gastro-esophageal reflux disease is a common condition, affecting 25%-40% of the population. Increasing attention has been paid to the relationship between Helicobacter pylori infection and reflux esophagitis. The aim of this study was to investigate the association between CagA+ H. pylori and endoscopically proven gastro-esophageal reflux disease. The study group included 60 hospital patients with gastro-esophageal reflux disease between 2007 and 2009 as compared with 30 healthy patients from a control group that was age and sex matched. Helicobacter pylori CagA+ was identified by an immunological test (Immunochromatography test) (ACON, USA). Helicobacter pyloriCagA+ was present in 42/60 (70%) of the patients with gastro-esophageal reflux disease and in 11/30 (36.6%) patients in the control group (p=0.002). The Odds ratio = 0.8004 with 95% Confidence Interval = from 0.3188 to 2.0094. The relative risk=1.35 that indicates an association between Helicobacter pylori and disease. The presence of Helicobacter pylori is significantly increased in patients with gastro-esophageal reflux disease as compared with the control group.

  6. Endoscopic and laparoscopic treatment of gastroesophageal reflux.

    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.

    Full Text Available Abstract Background Gastro-oesophageal reflux disease (GORD symptoms are common in asthma and have been extensively studied, but less so in the Asian continent. Reflux-associated respiratory symptoms (RARS have, in contrast, been little-studied globally. We report the prevalence of GORD symptoms and RARS in adult asthmatics, and their association with asthma severity and medication use. Methods A cross-sectional analytical study. A validated interviewer-administered GORD scale was used to assess frequency and severity of seven GORD symptoms. Subjects were consecutive asthmatics attending medical clinics. Controls were matched subjects without respiratory symptoms. Results The mean (SD composite GORD symptom score of asthmatics was significantly higher than controls (21.8 (17.2 versus 12.0 (7.6; P P Conclusions GORD symptoms and RARS were more prevalent in a cohort of Sri Lankan adult asthmatics compared to non-asthmatics. Increased prevalence of RARS is associated with both typical and atypical symptoms of GORD. Asthma disease and its severity, but not asthma medication, appear to influence presence of GORD symptoms.

    Coeliac disease (CD) has been linked to gastro-oesophageal reflux disease (GORD). Previous studies have demonstrated an increased prevalence of reflux in patients with CD. However data on the risk for CD in patients presenting with reflux are conflicting. The aim of this study was to establish the prevalence of CD in patients with GORD and to elucidate the mechanisms for reflux symptoms in newly diagnosed CD patients. Group A: patients who had undergone routine duodenal biopsy were prospectively recruited between 2004 and 2014. Diagnostic yield was compared with that of a screening cohort. Group B: 32 patients with newly diagnosed CD who had undergone oesophageal manometry and 24-h pH studies were prospectively recruited. Group A: 3368 patients (58.7% female, mean age 53.4 years) underwent routine duodenal biopsy. Of these patients, 850 (25.2%) presented with GORD. The prevalence of CD among GORD patients was 1.3% (0.7-2.4%), which was not significantly higher than that in the general population (P=0.53). Within the context of routine duodenal biopsy at endoscopy (when corrected for concurrent symptoms, age and sex), reflux was found to be negatively associated with CD [adjusted odds ratio 0.12 (0.07-0.23), Preflux. On manometry, 9% had a hypotensive lower oesophageal sphincter and 40.6% had oesophageal motor abnormalities, with 25% significantly hypocontractile. On pH studies, 33% demonstrated reflux episodes. The prevalence of undiagnosed CD among GORD patients is similar to that in the general population, and routine duodenal biopsy cannot be recommended. A significant number of patients with newly diagnosed CD were found to have reflux and/or oesophageal dysmotility on pH/manometry studies; this may explain the high prevalence of reflux symptoms in CD.

    Non-erosive reflux disease (NERD) patients are more sensitive than erosive esophagitis patients to weakly acidic reflux and to the presence of gas in the refluxate. Intra-esophageal acid perfusion sensitizes esophageal receptors to mechanical and chemical stimuli. To establish whether acid sensitization plays a role in the perception of weakly acidic and mixed reflux episodes, 29 NERD patients, responders and 14 non-responders to proton pump inhibitors (PPIs), underwent pH-impedance monitoring. Non-responders repeated the study while on PPIs. To assess the effect of acid exposure on symptom perception, the time period with pH below 4 was measured in 15- and 30-minute time-windows preceding the onset of each reflux episode. Considering weakly acidic and mixed refluxes, both in responder and non-responder patients (off PPIs), the symptomatic refluxes were preceded by a significantly higher cumulative acid exposure than the asymptomatic refluxes. In all patients, following acid reflux, the percentage of symptomatic weakly acidic reflux episodes was significantly higher than that of asymptomatic refluxes. Non-responder patients, off-treatment, were characterized by a lower proportion of weakly acidic reflux and mixed reflux episodes. In the non-responder patients on PPI, only mixed and weakly symptomatic reflux episodes were preceded by a higher cumulative acid exposure. In NERD patients, spontaneous acid reflux enhances subsequent reflux perception, regardless of acidity or liquid/mixed composition of episodes; in non-responder patients on PPIs, only the perception of mixed and weakly acidic reflux episodes seems to be mediated by a preceding acid exposure. © 2013 John Wiley & Sons Ltd.

    110 patients with suspected oesophageal symptoms were investigated by means of oesophageal endoscopy (OE), 24-h pH- metry, and oesophageal scintigraphy (ES). When 24-h pH-metry formed the basis for diagnosis of gastrooesophageal reflux disease (GERD), the sensitivity for ES at abdominal compression was 64%, but no statistically significant differences were found among erect refluxers, supine refluxers, and comibined refluxers. Only 4% of the GERD patients had pathologic oesophageal clearing at ES. The more severe the macroscopic oesophagitis found by OE, the more pronounced were the abnormal findings at 24-h pH-metry and at ES with abdominal compression. Increased postprandial reflux was associated with gastro-oesophageal reflux and hiatal hernia at ES with abdominal compression and the most severe form of oesophagitis, respectively. It is concluded that ES has too low sensitivity to be recommended as a screening test for GERD. Nevertheless, the specificity of 76% can to some extent help us to rule out GERD in patients. 19 refs., 7 tabs.

    Full Text Available The practice of feeding infants expressed breast milk is increasing in the United States, but the impacts on infant and maternal health are still understudied. This study examines the monthly incidence of regurgitation (gastro-esophageal reflux in exclusively breast milk fed infants from ages two to six months. Among infants whose mothers participated in the Infant Feeding Practices II Study (IFPS II; 2005–2007, data on reflux and feeding mode were collected by monthly questionnaires. A longitudinal, repeated measures analysis was used, with feeding mode lagged by one month in order to compare reflux incidence among infants fed directly at the breast to infants receiving pumped breast milk. Mothers in both feeding groups had similar characteristics, although a greater proportion feeding at least some pumped milk were primiparous. The number of exclusively breastfed infants decreased steadily between months 2 and 6, although the proportion fed at the breast remained similar over time. An association between feeding mode and reflux incidence was not found; however, the analyses were limited by a small number of reported reflux cases. More studies are needed to further explain the relationship between different feeding modes and infant reflux.

    Increased levels of anxiety and depression have been associated with esophageal hyperalgesia and an increased risk of gastroesophageal reflux disease (GERD). We investigated the effects of anxiety and depression on GERD symptoms and the perception of reflux episodes in a well-characterized group of patients. We performed a prospective study of 225 consecutive patients who had symptoms of GERD evaluated. Patients underwent ambulatory 24-hour pH impedance monitoring, and levels of anxiety and depression were assessed using the Hospital Anxiety and Depression Scale. GERD was diagnosed in 147 patients (78 patients had functional heartburn); 36 patients were hypersensitive to gastroesophageal reflux. Among patients with GERD, increased levels of anxiety were associated with more severe retrosternal pain and retrosternal burning. Furthermore, increased levels of anxiety and depression each were associated with lower scores of the mental component of quality of life questionnaire. Levels of anxiety or depression were not associated with the number of reflux symptoms reported during 24-hour pH impedance monitoring or with the number of symptoms associated with a reflux event. Among GERD patients with hypersensitivity to reflux, levels of anxiety and depression and decreases in quality of life were similar to those of other patients with GERD. Patients with functional heartburn had higher levels of anxiety than patients with GERD. In patients with GERD, increased levels of anxiety are associated with increased severity of retrosternal pain and heartburn and reduced quality of life. Patients with GERD with hypersensitivity to gastroesophageal reflux have similar levels of anxiety and similar quality-of-life scores as other patients with GERD. Copyright © 2015 AGA Institute.

    Full Text Available The purpose of this study was to explore the relationship between the intensity of acid reflux and severity of esophageal tissue damage in a cross-sectional study of patients with gastroesophageal reflux disease (GERD. Seventy-eight patients with were selected in accordance with the strict 24-hour ambulatory esophageal pHmetry (24h-pHM criteria and distributed into three age groups: Group A: 14 - 24 years of age. Group B: 25 - 54; and Group C: 55 - 64. The 24h-pHM was carried out in accordance with DeMeester standardization, and the Savary-Miller classification for the diagnosis of reflux esophagitis was used. The groups were similar in 24h-pHM parameters (p > 0.05, having above normal values. For the study group as a whole, there was no correlation between age group and intensity of acid reflux, and there was no correlation between intensity of acid reflux and severity of esophageal tissue damage. However, when the same patients were sub-grouped in accordance with the depth of their epithelial injury and then distributed into age groups, there was a significant difference in esophagitis without epithelial discontinuity. Younger patients had less epithelial damage than older patients. Additionally, although there was a significant progression from the least severe to the moderate stages of epithelial damage among the age groups, there was no apparent difference among the age groups in the distribution between the moderate stages and most severe stages. The findings support the conclusion that the protective response of individuals to acid reflux varies widely. Continued aggression by acid reflux appears to lead to the exhaustion of individual mechanisms of epithelial protection in some patients, but not others, regardless of age or duration of the disease. Therefore, the diagnosis and follow-up of GERD should include both measurements of the quantity of refluxed acid and an assessment of the damage to the esophageal epithelium.

    The incidence of gastroesophageal reflux disease (GERD) is increasing in Korea. The aim of this study was to evaluate the relationship between GERD symptoms and dietary factors in Korea. From January 2007 to April 2008, 162 subjects were enrolled (81 in GERD group and 81 in control group). They were asked to complete the questionnaires about GERD symptoms and dietary habits. The symptom severity score was recorded by visual analogue scale. Subjects with overweight or obesity had an increased risk for GERD (OR, 2.52; 95% CI, 1.18-5.39). Irregular dietary intake was one of the risk factors for GERD (OR, 2.33; 95% CI, 1.11-4.89). Acid regurgitation was the most suffering (2.85 ± 2.95 by visual analogue scale) and frequent reflux-related symptom (57.5%) in GERD. Noodles (OR, 1.22; 95% CI, 1.12-1.34), spicy foods (OR, 1.09; 95% CI, 1.02-1.16), fatty meals (OR, 1.20; 95% CI, 1.09-1.33), sweets (OR, 1.42; 95% CI, 1.00-2.02), alcohol (OR, 1.16; 95% CI, 1.03-1.31), breads (OR, 1.17; 95% CI, 1.01-1.34), carbonated drinks (OR, 1.69; 95% CI, 1.04-2.74) and caffeinated drinks (OR,1.41; 95% CI, 1.15-1.73) were associated with symptom aggravation in GERD. Among the investigated noodles, ramen (instant noodle) caused reflux-related symptoms most frequently (52.4%). We found that noodles, spicy foods, fatty meals, sweets, alcohol, breads, carbonated drinks and caffeinated drinks were associated with reflux-related symptoms.

  17. Extra-Esophageal Pepsin from Stomach Refluxate Promoted Tonsil Hypertrophy.

    Full Text Available Gastroesophageal reflux is associated with numerous pathologic conditions of the upper aerodigestive tract. Gastric pepsin within reflux contributes to immunologic reactions in the tonsil. In this study, we aimed to find the relationships between pepsin and tonsillar hypertrophy.We explored the notion whether tonsillar hypertrophy was due to pepsin-mediated gastric reflux in tonsil hypertrophy. Fifty-four children with tonsil hypertrophy and 30 adults with tonsillitis were recruited before surgical treatment. Blood and tonsil tissues from each patient were harvested for analysis of changes in lymphocyte and macrophage numbers coupled with histological and biochemical analysis. Pepsin was expressed at different levels in tonsil tissues from each tonsillar hypertrophy. Pepsin-positive cells were found in the crypt epithelium, surrounding the lymphoid follicle with developing fibrosis, and also surrounding the lymphoid follicle that faced the crypt. And also, pepsin staining was well correlated with damaged tonsillar squamous epithelium and TGF-β1 and iNOS expression in the tonsil section. In addition, pepsin and TGF-β1-positive cells were co-localized with CD68-positive cells in the crypt and surrounding germinal centers. In comparison of macrophage responsiveness to pepsin, peripheral blood mononuclear cells (PBMNCs were noticeably larger in the presence of activated pepsin in the child group. Furthermore, CD11c and CD163-positive cells were significantly increased by activated pepsin. However, this was not seen for the culture of PBMNCs from the adult group.The lymphocytes and monocytes are in a highly proliferative state in the tonsillar hypertrophy and associated with increased expression of pro-inflammatory factors as a result of exposure to stomach reflux pepsin.

    A more prominent role for the youth healthcare physician: Youth Healthcare physicians reflect on the Dutch Paediatric Association (NVK) guideline entitled 'Gastro-oesophageal reflux (disease) in children aged 0-18 years'. This guideline states that medicinal treatment is given to these children too often. Dutch Youth Healthcare physicians see a large number of children with gastro-oesophageal reflux, with or without additional symptoms. The most common symptoms (crying and diminished weight gain) might be present even in the absence of reflux. Parents should be given advice and support when they are worried about reflux, crying or low weight gain. A lower weight gain curve on the growth chart is normal in breastfed children, and crying might be due to factors such as lack of routine or stimulus reduction. Overfeeding might also be the cause. Parents should be supported and followed up, with or without treatment, as necessary. Youth Healthcare professionals could perform this task.

    Scintigraphic techniques are the only quantitative methods for the evaluation of esophageal transit and gastroesophageal reflux. By comparison, other techniques are not quantitative and are either indirect, inconvenient, or less sensitive. Methods, such as perfusion techniques, which measure flow, require the introduction of a tube assembly into the gastrointestinal tract with the possible introduction of artifacts into the measurements due to the indwelling tubes. Earlier authors using radionuclide markers, introduced a method for measuring gastric emptying which was both tubeless and quantitative in comparison to other techniques. More recently, a number of scintigraphic methods have been introduced for the quantitation of esophageal transit and clearance, the detection and quantitation of gastroesophageal reflux, the measurement of gastric emptying using a mixed solid-liquid meal, and the quantitation of enterogastric reflux. This chapter reviews current techniques for the evaluation of esophageal transit and gastroesophageal reflux

    Thirty-six children with urinary tract infection aged 6 months to 14 years (mean age 4 1/2 years) were studied sequentially using direct radionuclide (RNC) and conventional voiding cystourethrography (VCU). Vesicoureteral reflux (VUR) was detected equally well by both methods. Twenty-seven refluxing ureters were found by RNC, 23 by VCU and 22 by both methods. Radiologic grade of reflux may be determined approximately with the isotope technique from the volume of regurgitating urine und duration of reflux, at a much decreased radiation exposure. Residual urine was also measured by RNC and found to be higher in children with VUR. RNC is a reliable method for detecting and grading VUR and should effectively replace VCU as the follow-up examination of choice. (orig.)

    Mechanisms of gastro-oesophageal reflux were studied by oesophageal manometry and pH monitoring in 33 children: nine controls, 15 with gastro-oesophageal reflux alone, and nine with reflux oesophagitis. A total of 122 episodes of reflux were analysed in detail: 82 (67%) were synchronous with swallowing and 40 (33%) asynchronous. Infants with trivial symptoms had gastro-oesophageal reflux synchronous with swallowing, whereas those with serious symptoms had slower acid clearance and asynchronous reflux. There were significant differences in lower oesophageal sphincter pressure and amplitude of oesophageal contractions between controls and patients with both gastro-oesophageal reflux and reflux oesophagitis. In reflux oesophagitis there was a decrease in lower oesophageal sphincter pressure and the contractions had a bizarre waveform suggesting a neuropathic process. PMID:3202640

    Gastroesophageal reflux disease is a worldwide prevalent condition that exhibits a large variety of signs and symptoms of esophageal or extra-esophageal nature and can be related to the esophagic adenocarcinoma. In the last few years, greater importance has been given to the influence of physical exercises on it. Some recent investigations, though showing conflicting results, point to an exacerbation of gastroesophageal reflux during physical exercises. To evaluate the influence of physical activities in patients presenting with erosive and non erosive disease by ergometric stress testing and influence of the lower esophageal sphincter tonus and body mass index during this situation. Twenty-nine patients with erosive disease (group I) and 10 patients with non-erosive disease (group II) were prospectively evaluated. All the patients were submitted to clinical evaluation, followed by upper digestive endoscopy, manometry and 24 h esophageal pH monitoring. An ergometric testing was performed 1 h before removing the esophageal pH probe. During the ergometric stress testing, the following variables were analyzed: test efficacy, maximum oxygen uptake, acid reflux duration, gastroesophageal reflux symptoms, influence of the lower esophageal sphincter tonus and influence of body mass index in the occurrence of gastroesophageal reflux during these physical stress. Maximum oxigen consumption or VO 2 max, showed significant correlation when it was 70% or higher only in the erosive disease group, evaluating the patients with or without acid reflux during the ergometric testing (p=0,032). The other considered variables didn't show significant correlations between gastroesophageal reflux and physical activity (p>0,05). 1) Highly intensive physical activity can predispose the occurrence of gastroesophageal reflux episodes in gastroesophageal reflux disease patients with erosive disease; 2) light or short sessions of physical activity have no influence on reflux, regardless of body

    Acid changes in gastroesophageal reflux with vary component in the food have less been studied, especially carbohydrate. We plan to clarify the effect of different carbohydrate density on low esophageal acid and reflux symptoms of patients with gastroesophgeal reflux disease. Twelve patients (52 ± 12 years old; five female) with gastroesophageal reflux disease were recruited for the prospective crossover study. Each patient was invited for panendoscope, manometry and 24 h pH monitor. The two formulated liquid meal, test meal A: 500 ml liquid meal (containing 84.8 g carbohydrate) and B: same volume liquid meal (but 178.8 g carbohydrate) were randomized supplied as lunch or dinner. Reflux symptoms were recorded. There are significant statistic differences in more Johnson-DeMeester score (p = 0.019), total reflux time (%) (p = 0.028), number of reflux periods (p = 0.026) and longest reflux (p = 0.015) after high carbohydrate diet than low carbohydrate. Total reflux time and number of long reflux periods more than 5 min are significant more after high carbohydrate diet. More acid reflux symptoms are found after high carbohydrate diet. High carbohydrate diet could induce more acid reflux in low esophagus and more reflux symptoms in patients with gastroesophageal reflux disease. Copyright © 2018. Published by Elsevier B.V.

    Gastroesophageal reflux disease (GERD) is a major digestive health problem with a high and increasing incidence worldwide. Peroral endoscopic cardial constriction (PECC) was developed by our group to provide a less invasive treatment for GERD.In this preliminary follow-up study, 16 patients were enrolled and 13 patients with GERD were targeted for analysis according to the Los Angeles classification of reflux esophagitis. The GERD health-related quality of life (GERD-HRQL) scale and esophageal pH monitoring were applied to assess clinical efficiency at 3 and 6 months after PECC treatment, respectively.All GERD patients successively received PECC, and no severe treatment-related complication was reported. Before PECC treatment, the GERD-HRQL scale was 19.92 ± 7.89. At 3 and 6 months after treatment, the GERD-HRQL scale was 4.46 ± 4.31 and 5.69 ± 5.07, respectively. DeMeester score was 125.50 ± 89.64 before PECC treatment, and 16.97 ± 12.76 and 20.32 ± 15.22 at 3 and 6 months after PECC treatment. Furthermore, the fraction time of a pH below 4 significantly decreased at 3 and 6 months after PECC treatment. Fraction time at pH reflux of stomach contents.

    Epidemiological studies of gastro-oesophageal reflux disease (GORD) are confounded by the lack of a standardized definition and a diagnostic 'gold-standard' for the disorder. In Western countries, 20-40% of the adult population experience heartburn, which is the cardinal symptom of GORD, but only some 2% of adults have objective evidence of reflux oesophagitis. The incidence of GORD increases with age, rising dramatically after 40 years of age. There is also wide geographical variation in prevalence. Complications, including oesophageal ulcer and stricture, and Barrett's oesophagus, are found in up to 20% of patients with verified reflux oesophagitis. The signs and symptoms of GORD often wax and wane in intensity, and spontaneous remissions have been reported. In most cases, however, GORD is a chronic condition that returns shortly after discontinuing therapy. Although GORD causes substantial morbidity, the annual mortality rate due to GORD is very low (approximately 1 death per 100,000 patients), and even severe GORD has no apparent effect on longevity, although the quality of life can be significantly impaired. There are data to suggest that the use of non-steroidal anti-inflammatory drugs (NSAIDs) contributes to oesophagitis and stricture formation in patients with GORD. Although these data are not conclusive, it seems prudent, if possible, to avoid the use of NSAIDs in patients with GORD, particularly those with oesophageal stricture.

    The mechanisms underlying symptoms in non-erosive reflux disease (NERD) remain to be elucidated. Non-erosive reflux disease patients appear to be more sensitive to intraluminal stimula than erosive patients, the proximal oesophagus being the most sensitive. In order to assess regional oesophageal changes in reflux acidity and sensitivity to reflux, according either to the acidity or the composition of the refluxate, combined multiple pH and multiple pH-impedance (pH-MII) was performed in 16 NERD patients. According to multiple pH-metry, 29% and 12% of reflux events reached the middle and proximal oesophagus respectively, and 35% and 19% according to conventional pH-MII (P acid reflux became weakly acidic at the proximal oesophagus. In all patients, the frequency of symptomatic refluxes, both acid and weakly acidic, was significantly higher at the proximal, compared with distal oesophagus (25 +/- 8%vs 11 +/- 2% for acid reflux and 27 +/- 8%vs 8 +/- 2% for weakly acidic reflux; P reflux. As approximately 30% of acid reflux becomes weakly acidic along the oesophageal body, to better characterize proximal reflux, in clinical practice, combined proximal pH-impedance monitoring should be used. In NERD patients, the proximal oesophagus seems to be more sensitive to both acid and weakly acidic reflux.

    An investigation to detect food-stimulated gastro-oesophageal (GE) reflux was carried out in 54 consecutive fasting patients, 35 of whom experienced reflux while 19 did not. All patients then received a standard meal (566 kcal), and the investigation was repeated 1 h afterward. Of the 35 with GE reflux in the fasting state, 33 also had GE reflux in the postprandial state, and 17 of the 19 patients with no GE reflux while fasting also had none in the postprandial state. It is concluded that the radiological method can identify most patients in whom food-stimulated GE reflux could be of clinical significance. (orig.).

    This study is to determine the association of ambulatory pH monitoring (24hr pH) with symptoms of gastroesophageal reflux and its other investigations. The clinical and epidemiological profiles of subjects referred for reflux disorders are also studied. Symptoms or group of symptoms, profiles and prior investigations of 1259 consecutive pediatric subjects (with 1332 24hr pH studies performed) referred for evaluation of reflux disorders between 1988 and 2012 were retrospectively studied. Chi-square or fisher exact test was used for hypothesis testing, student t-test for the comparison of means and the Wilcoxon rank-sum test for comparing medians of continuous variables. Gastroesophageal reflux disease (GERD), defined as reflux causing major symptoms and complications, was diagnosed in 57.5% subjects of the total sample. Forty-three percent were girls and 56.7% were boys. The most common age group was between 4 months and 2 years (51.2%). Vomiting (64.4%) and irritability (74%) were the most common symptoms with the neurological conditions (23.2%) being the most frequent underlying condition. The parameters used in 24hr pH were significantly higher in those diagnosed with GERD (P reflux disorders. 24hr pH is reliable and should be considered routine in reflux disorders, as it identifies patients with pathologic reflux and avoids a needless surgery. © 2016 International Society for Diseases of the Esophagus.

    To analyse the association between 24-hour multichannel intraluminal impedance-pH (24-h MII-pH) parameters and each item of the reflux finding score (RFS) to determine whether the laryngoscopic findings of the RFS could reflect the characteristics of reflux in patients with laryngopharyngeal reflux (LPR). Prospective cohort study. Tertiary care referral medical centre. Patients complaining of LPR symptoms were evaluated via a 24-hour MII-pH. Among them, 99 patients whose LPR was confirmed via 24-hour MII-pH were enrolled in this study. Correlations between RFS ratings and 24-hour MII-pH parameters were evaluated and compared between patients with or without each laryngoscopic finding used in the RFS. Subglottic oedema had a statistically significant positive correlation with number of non-acid LPR and non-acid full column reflux events. Ventricular obliteration and posterior commissure hypertrophy showed a significant correlation with non-acid exposure time and total reflux exposure time. We also found a significant correlation between granuloma/granulation score and number of acid LPR events. The numbers of non-acid LPR and full column reflux events in patients with subglottic oedema were significantly higher than those without subglottic oedema. Among the laryngoscopic findings used in the RFS, subglottic oedema is specific for non-acid reflux episodes, and granuloma/granulation is specific for acid reflux episodes. © 2017 John Wiley & Sons Ltd.

    Full Text Available CONTEXT: Gastroesophageal reflux disease is a chronic disease in which gastroduodenal contents reflux into the esophagus. The clinical picture of gastroesophageal reflux disease is usually composed by heartburn and regurgitation (typical manifestations. Atypical manifestations (vocal disturbances and asthma may also be complaint. OBJECTIVE: To analyse the clinical, endoscopic, manometric and pHmetric aspects of patients suffering from gastroesophageal reflux disease associated with vocal disturbances. METHODS: Fifty patients with gastroesophageal reflux disease were studied, including 25 with vocal disturbances (group 1 - G1 and 25 without these symptoms (group 2 - G2. All patients were submitted to endoscopy, manometry and esophageal pHmetry (2 probes. The group 1 patients were submitted to videolaryngoscopy. RESULTS: Endoscopic findings: non-erosive reflux disease was observed in 95% of G1 patients and 88% of G2. Videolaryngoscopy: vocal fold congestion, asymmetry, nodules and polyps were observed in G1 patients. Manometric findings: pressure in the lower esophageal sphincter (mm Hg: 11.6 ± 5.2 in G1 and 14.0 ± 6.2 in G2 (P = 0.14; pressure in the upper esophageal sphincter (mm Hg: 58.4 ± 15.9 in G1 and 69.5 ± 30.7 in the controls. pHmetric findings: De Meester index: 34.0 ± 20.9 in G1 and 15.4 ± 9.4 in G2 (P<0.001; number of reflux episodes in distal probe: 43.0 ± 20.4 in G1 and 26.4 ± 17.2 in G2 (P = 0.003; percentage of time with esophageal pH value lower than 4 units (distal sensor: 9.0% ± 6.4% in G1 and 3.4% ± 2.1% in G2 (P<0.001; number of reflux episodes in proximal probe: 7.5 ± 10.9 in G1 and 5.3 ± 5.7 in G2 (P = 0.38; percentage of time with esophageal pH values lower than 4 units (Proximal probe: 1.2 ± 2.7 in G1 and 0.5 ± 0.7 in G2 (P = 0.21.

    Full Text Available The aim of this study was to compare the different diagnostic approaches in detection of gastroesophageal reflux disease in children presented with symptoms suggesting gastroesophageal reflux disease.The study design was cross sectional. The study retrospectively included all children who underwent combined multiple intraluminal impedance and pH (pH-MII monitoring due to gastrointestinal and/or extraesophageal symptoms suggesting gastroesophageal reflux disease at University Children's Hospital in Belgrade, from July 2012 to July 2016.A total of 218 (117 boys/101 girls, mean age 6.7 years (range 0.06-18.0 years, met the inclusion criteria. Gastroesophageal reflux disease was found in 128 of 218 children (57.4% by pH-MII and in 76 (34.1% children by pH metry alone. Using pH-MII monitoring as gold standard, sensitivity of pH-metry was lowest in infants (22.9%, with tendency to increase in older age groups (reaching 76.4% in children ≥ 9 years. The sensitivity of pH-metry alone in children with extraesophageal symptoms was 38.1%, while the sensitivity of pH-metry in children with gastrointestinal symptoms was 63.8%. Reflux esophagitis was identified in 31 (26.1% of 119 children who underwent endoscopy. Logistic regression analysis showed that best predictors of endoscopic reflux esophagitis are the longest acid episode (OR = 1.52, p<0.05 and DeMeester reflux composite score (OR = 3.31, p<0.05. The significant cutoff values included DeMeester reflux composite score ≥ 29 (AUC 0.786, CI 0.695-0.877, p<0.01 and duration of longest acid reflux ≥ 18 minutes (AUC 0.784, CI 0.692-0.875, p<0.01.The results of our study suggested that compared with pH-metry alone, pH-MII had significantly higher detection rate of gastroesophageal reflux disease, especially in infants. Our findings also showed that pH-MII parameters correlated significantly with the endoscopically confirmed erosive esophagitis.

  1. Gastroesophageal Reflux Disease: Medical or Surgical Treatment?

    Directory of Open Access Journals (Sweden)

    2009-01-01

    Full Text Available Background. Gastroesophageal reflux disease is a common condition with increasing prevalence worldwide. The disease encompasses a broad spectrum of clinical symptoms and disorders from simple heartburn without esophagitis to erosive esophagitis with severe complications, such as esophageal strictures and intestinal metaplasia. Diagnosis is based mainly on ambulatory esophageal pH testing and endoscopy. There has been a long-standing debate about the best treatment approach for this troublesome disease. Methods and Results. Medical treatment with PPIs has an excellent efficacy in reversing the symptoms of GERD, but they should be taken for life, and long-term side effects do exist. However, patients who desire a permanent cure and have severe complications or cannot tolerate long-term treatment with PPIs are candidates for surgical treatment. Laparoscopic antireflux surgery achieves a significant symptom control, increased patient satisfaction, and complete withdrawal of antireflux medications, in the majority of patients. Conclusion. Surgical treatment should be reserved mainly for young patients seeking permanent results. However, the choice of the treatment schedule should be individualized for every patient. It is up to the patient, the physician and the surgeon to decide the best treatment option for individual cases.

    1981-01-01

    A concept of closed reflux system for stable isotope fractionation by chemical exchange method has been introduced. In a closed system a chemical agent used to convert one chemical species of an isotopic exchange reaction into the other at the product end is regenerated on site by means of an electrochemical or thermal process. It offers a convenience of eliminating the needs for transporting chemicals to and from the site and an advantage of allowing leniency in the degree of completeness of the reflux reaction. Feasibility of use of Fe(II) salt solutions in a closed reflux system for the Nitrox process for 15 N fractionation has been studied. Two of such systems, FeSO 4 in H 2 SO 4 and Fe(ClO 4 ) 2 in HClO 4 , are adopted for packed column operation. For both systems, the rate of reduction of nitric acid increases with increasing acid concentration, the solubility of the salts decreases with the increasing acid concentration, and the reflux reaction can be made to go to completion. Evaluation of such a closed reflux system will have to include that of performance of regenerative process

    The spectrophotometric probe, which uses bilirubin as a marker for the detection of duodenoesophagic reflux is subject to interference from strongly colored foods, which can cause erroneously high bilirubin absorbance readings. To overcome this problem it is necessary to ingest a diet that is free from such substances. To test the absorbance of 48 different food substances in an in vitro environment. Dry foods were blended with water or milk and non-dry solid foods were blended undiluted. It was utilized the proper calibration recipient to test them. The absorbance of weakly colored foods was usually lesser than the commonly accepted threshold of 0.14, and the absorbance of strongly colored foods was usually above this. Thirty-two from the 48 substances tested are suitable when the absorbance threshold is set at 0.14, but scrambled eggs, lacteous flour mush, green beans, beetroot, carrot, chayote, squash, "baroa" potato, boiled corn, orange, cashew, purple grape, avocado, mango, papaya and peach can alter the results and must be avoided. From the foods evaluated, enough are suitable at the 0.14 threshold to enable a suitable diet to be constructed for most patients during Bilitec studies.

    Christiansen, T.; Funch-Jensen, P.; Jacobsen, N.O.; Thommesen, P.

    In a prospective study, 26 patients with symptoms of reflux oesophagitis underwent a barium examination for gastro-oesophageal reflux after food stimulation, and endoscopy with biopsy from different levels of the oesophagus. Radiologic grading of the gastro-oesophageal reflux depending on the height of the reflux into the oesophagus was performed, and this was correlated to the microscopic appearance at different levels in the oesophagus. Complete agreement between the radiologic grading and the histology was found in 69 per cent of the cases, and when gastro-oesophageal reflux was demonstrated the agreement was 75 per cent. Accordingly, the results showed a good accordance between the two variants, indicating that the height of the reflux during the food stimulated test may be truly indicative of the reflux height under non-test conditions.

    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

The study retrospectively included all children who underwent combined multiple intraluminal impedance and pH (pH-MII) monitoring due to gastrointestinal and/or extraesophageal symptoms suggesting gastroesophageal reflux disease at University Children's Hospital in Belgrade, from July 2012 to July 2016. A total of 218 (117 boys/101 girls), mean age 6.7 years (range 0.06-18.0 years), met the inclusion criteria. Gastroesophageal reflux disease was found in 128 of 218 children (57.4%) by pH-MII and in 76 (34.1%) children by pH metry alone. Using pH-MII monitoring as gold standard, sensitivity of pH-metry was lowest in infants (22.9%), with tendency to increase in older age groups (reaching 76.4% in children ≥ 9 years). The sensitivity of pH-metry alone in children with extraesophageal symptoms was 38.1%, while the sensitivity of pH-metry in children with gastrointestinal symptoms was 63.8%. Reflux esophagitis was identified in 31 (26.1%) of 119 children who underwent endoscopy. Logistic regression analysis showed that best predictors of endoscopic reflux esophagitis are the longest acid episode (OR = 1.52, preflux composite score (OR = 3.31, preflux composite score ≥ 29 (AUC 0.786, CI 0.695-0.877, preflux ≥ 18 minutes (AUC 0.784, CI 0.692-0.875, pgastroesophageal reflux disease, especially in infants. Our findings also showed that pH-MII parameters correlated significantly with the endoscopically confirmed erosive esophagitis.

    Patients with peptic esophagitis or typical complaints with respect to reflux without esophagitis and control persons (n = 68) were comparatively examined for gastroesophageal reflux by means of scintigraphy (after administration of test solutions labelled with /sup 99m/Tc-DTPA or after intravenous application of /sup 99m/Tc-pertechnetate) and by means of continuous intraesophageal p/sub H/ measurement. The scintigraphic test of the reflux was successful for very few patients only with reflux disease and a reflux detectable by measuring the p/sub H/. The application of pentagastrin failed in improving the scintigraphic detection of the reflux. The cause of the unsuccessful scintigraphic evidence for the majority of the reflux patients seems to be the relatively small reflux volume.

  15. Prevalence of gastro-oesophageal reflux disease symptoms and reflux-associated respiratory symptoms in asthma

    Science.gov (United States)

    2010-01-01

    Background Gastro-oesophageal reflux disease (GORD) symptoms are common in asthma and have been extensively studied, but less so in the Asian continent. Reflux-associated respiratory symptoms (RARS) have, in contrast, been little-studied globally. We report the prevalence of GORD symptoms and RARS in adult asthmatics, and their association with asthma severity and medication use. Methods A cross-sectional analytical study. A validated interviewer-administered GORD scale was used to assess frequency and severity of seven GORD symptoms. Subjects were consecutive asthmatics attending medical clinics. Controls were matched subjects without respiratory symptoms. Results The mean (SD) composite GORD symptom score of asthmatics was significantly higher than controls (21.8 (17.2) versus 12.0 (7.6); P < 0.001) as was frequency of each symptom and RARS. Prevalence of GORD symptoms in asthmatics was 59.4% (95% CI, 59.1%-59.6%) versus 28.5% in controls (95% CI, 29.0% - 29.4%). 36% of asthmatics experienced respiratory symptoms in association with both typical and atypical GORD symptoms, compared to 10% of controls (P < 0.001). An asthmatic had a 3.5 times higher risk of experiencing a GORD symptom after adjusting for confounders (OR 3.5; 95% CI 2.5-5.3). Severity of asthma had a strong dose-response relationship with GORD symptoms. Asthma medication use did not significantly influence the presence of GORD symptoms. Conclusions GORD symptoms and RARS were more prevalent in a cohort of Sri Lankan adult asthmatics compared to non-asthmatics. Increased prevalence of RARS is associated with both typical and atypical symptoms of GORD. Asthma disease and its severity, but not asthma medication, appear to influence presence of GORD symptoms.

    Gastroesophageal reflux disease is one of the most common disorders of the gastrointestinal tract. The prevalence of this disease ranges from 5% to 20% in Asia, Europe, and North America. The aim of this study was to estimate the burden of gastroesophageal reflux disease in Iran. Burden of gastroesophageal reflux disease in Iran was estimated for one year from 21 March 2006 to 20 March 2007. The definition was adjusted with ICD-code of K21. Incident-based disability-adjusted life year (DALY) was used as the unit of analysis to quantify disease burden. A simplified disease model and DisMod II software were used for modeling. The annual incidence for total population of males and females in Iran was estimated 17.72 and 28.06 per 1000, respectively. The average duration of gastroesophageal reflux disease as a chronic condition was estimated around 10 years in both sexes. Total DALYs for an average of 59 symptomatic days per year was estimated 153,554.3 (60,330.8 for males and 93,223.5 for females).   The results of this study showed that reflux imposes high burden and high financial costs on the Iranian population. The burden of this disease in Iran is more similar to that of European countries rather than Asian countries. It is recommended to consider the disease as a public health problem and make decisions and public health plans to reduce the burden and financial costs of the disease in Iran.

    Follicular tracheitis (also known as tracheal cobblestoning) is an entity that is poorly described and of unclear significance. The objective of this study was to better define follicular tracheitis and determine the association between the clinical finding of follicular tracheitis on bronchoscopy and objective evidence of gastroesophageal reflux disease. Retrospective chart review of children with recurrent croup having undergone a rigid bronchoscopy and an investigation for gastroesophageal reflux between 2001 and 2013. 117 children with recurrent croup children age 6-144 months were included in the study. Follicular tracheitis was noted on 41% of all bronchoscopies. Fifty-nine percent of all children who underwent bronchoscopy were diagnosed with gastroesophageal reflux on at least one investigation. Forty-nine of 117 children underwent a pH probe study, and 51% were found to have evidence of reflux on this study. Nine children were diagnosed with eosinophilic esophagitis. Three patients underwent a biopsy of the follicular tracheitis lesions, which revealed chronic inflammation. There was no evidence of an association between findings of follicular tracheitis and a positive test for gastroesophageal reflux (p=0.52) or a positive pH probe study (p=0.64). There was no association between follicular tracheitis and subglottic stenosis (p=0.33) or an history of asthma and/or atopy (p=0.19). In children with recurrent croup, follicular tracheitis remains an unspecific finding associated with an inflammatory disorder of unknown etiology. Copyright © 2015 Elsevier Ireland Ltd.

  18. Reflux revisited: advancing the role of pepsin.

    2012-01-01

    Gastroesophageal reflux disease is mediated principally by acid. Today, we recognise reflux reaches beyond the esophagus, where pepsin, not acid, causes damage. Extraesophageal reflux occurs both as liquid and probably aerosol, the latter with a further reach. Pepsin is stable up to pH 7 and regains activity after reacidification. The enzyme adheres to laryngeal cells, depletes its defences, and causes further damage internally after its endocytosis. Extraesophageal reflux can today be detected by recognising pharyngeal acidification using a miniaturised pH probe and by the identification of pepsin in saliva and in exhaled breath condensate by a rapid, sensitive, and specific immunoassay. Proton pump inhibitors do not help the majority with extraesophageal reflux but specifically formulated alginates, which sieve pepsin, give benefit. These new insights may lead to the development of novel drugs that dramatically reduce pepsinogen secretion, block the effects of adherent pepsin, and give corresponding clinical benefit."For now we see through a glass, darkly."-First epistle, Chapter 13, Corinthians.

  19. Gastroesophageal Reflux Disease and Alkaline Reflux: the Mechanisms of the Development and Therapeutic Approach

    Directory of Open Access Journals (Sweden)

    T.D. Zviahintseva

    2016-11-01

    Full Text Available The article deals with gastroesophageal reflux disease (GERD — a pathology, which occupies a leading place among all acid-related diseases. The main mechanism of GERD is a violation of the motor-evacuation function of the stomach — slowing gastric emptying and duodenogastric reflux. Slow gastric emptying contributes to more frequent reflux, and the presence of duodenal contents in refluxate — alkaline reflux — is aggressive for the esophageal mucosa (EM. This is due to the presence of bile acids, lysolecithin and pancreatic enzymes in the esophageal refluxate. A long existing contact of aggressive factors in the stomach and the esophagus leads to the development of inflammatory and destructive lesions of the mucous membrane of these organs. According to many researchers, bile acids play a key role in the pathogenesis of the damaging effects on the EM. Drug correction of GERD with alkaline reflux includes, along with the administration of proton pump inhibitors, prokinetics (itopride hydrochloride and ursodeoxycholic acid preparations.

    Patients with typical reflux symptoms (heartburn/regurgitation) persisting despite proton pump inhibitor (PPI) therapy are not uncommon. Impedance-pH monitoring detects gastroesophageal reflux at all pH levels and may establish if ongoing symptoms on PPI therapy are associated with acid/nonacid reflux. Laparoscopic fundoplication is a therapeutic option in such patients but reflux parameters on PPI therapy and after intervention and their relationship with symptom persistence/remission have been scarcely studied. The aim of this study was to assess reflux parameters and their relationship with symptoms before and after laparoscopic fundoplication, on and off PPI therapy, respectively, in patients with PPI-unresponsive heartburn/regurgitation and with a positive symptom-reflux association and/or abnormal reflux parameters detected on PPI therapy. Impedance-pH monitoring was performed on high-dose PPI therapy and 3 months after laparoscopic fundoplication, off PPI therapy, in 40 patients with PPI-unresponsive heartburn/regurgitation. Symptoms were scored by a validated questionnaire. Esophageal acid exposure time as well as the number of total and proximal reflux events and of acid and weakly acidic refluxes decreased significantly after surgery: normal values were found in 100, 77, 95, 92 and 65% of cases, respectively. Weakly alkaline refluxes increased significantly postoperatively but neither before nor after intervention were associated with symptoms. All patients reported total/subtotal remission of heartburn/regurgitation 3 months after surgery. Laparoscopic fundoplication improves acid and weakly acidic reflux parameters when compared with PPI therapy. This improvement justifies the very high post-surgical symptom remission rate that we observed. Prolonged follow-up is warranted but our findings strongly support the surgical option in PPI failures.

    Improved identification of children with vesicoureteral reflux at risk for recurrent febrile urinary tract infection may impact management decisions. We hypothesized that reflux occurring earlier during bladder filling increases the duration of exposure of the kidneys to bacteria, and, therefore, increases the risk of pyelonephritis. Children with vesicoureteral reflux and detailed voiding cystourethrogram data were identified. Bladder volume at onset of reflux was normalized for age. Demographics, reflux grade, laterality, presence/absence of bladder-bowel dysfunction and breakthrough febrile urinary tract infections were assessed. Median followup was 24 months (IQR 12 to 52). A total of 208 girls and 47 boys were analyzed with a mean ± SD age at diagnosis of 3.1 ± 2.6 years. On univariate analysis history of febrile urinary tract infection (HR 2.17, 95% CI 1.33-2.85, p = 0.01), dilating vesicoureteral reflux (HR 1.6, 95% CI 1.05-2.42, p = 0.03) and bladder-bowel dysfunction (HR 1.66, 95% CI 0.99-2.75, p = 0.05) were associated with an increased risk of breakthrough febrile urinary tract infection. Median bladder volume at onset of reflux in children with breakthrough febrile urinary tract infection was significantly less (33.1%) than in those without infection (49.5%, p = 0.003). Reflux onset at 35% predicted bladder capacity or less was associated with a significantly increased risk of breakthrough febrile urinary tract infection on multivariate analysis (HR 1.58, 95% CI 1.05-2.38, p = 0.03). Children with early filling vesicoureteral reflux are at increased risk for breakthrough febrile urinary tract infection independent of reflux grade. Bladder volume at onset of reflux should be recorded during cystograms since it provides additional prognostic information about the risk of pyelonephritis and resolution, and may assist with counseling and clinical decision making.

    Extravesical detrusorrhaphy is a simple and safe approach to antireflux surgery; however, its use in Taiwan has seldom been reported. We report the outcomes of 15 patients (23 ureters) with primary vesicoureteral reflux who underwent extravesical detrusorrhaphy between January 1995 and April 1996, and describe the surgical technique. Overall, vesicoureteral reflux was cured in 22 of 23 ureters. Postoperative morbidity and complications were minimal. None of the patients had obstruction or significant hematuria. The discomfort related to bladder spasms during the postoperative period was subjectively decreased compared to the conventional transvesical technique. There was transient voiding inefficiency in three patients, as well as urinary retention in one, which resolved spontaneously after 4 weeks of Foley catheter drainage. Our experience showed that detrusorrhaphy is an effective way to correct vesicoureteral reflux with minimal morbidity and discomfort. Proper patient selection and strict adherence to the surgical principle are important for high success rates.

    1995-01-01

    The vesical-ureteral reflux is the most frequent uropathy in children. The diagnosis is made by uretero-cystography, often after pyelonephritis, sometimes after ante-natal diagnosis from echographic abnormalities. Spontaneous recovery is possible in 50 to 80% of cases. This is especially true in grade 1, 2 and 3, however complications may occur. They are more frequent in the case of reflux nephropathy with a resulting risk of hypertension and chronic renal failure. The therapeutic choice is between the conservative management with urinary antiseptics ad the surgical treatment with ureters re-implantation or endoscopic treatment. The therapeutic indications take into account vesical-ureteral reflux grades, the child's age, the associated diseases and the child's and parents' compliance. (authors). 22 refs., 2 figs

    A group of 97 individuals with typical symptoms of gastroesophageal reflux disease (GERD) was submitted to gastroesophageal reflux scintigraphy (GES) and compared to the results obtained from endoscopy, histopathology and 24 hours pHmetry. Twenty-four healthy individuals were used as a control group and they have done only the GERS. The results obtained showed that: a) the difference int he reflux index (RI) for the control group and the sick individuals was statistically significant (p < 0.0001); b) the correlation between GERS and the other methods showed the following results: sensitivity, 84%; specificity, 95%; positive predictive value, 98%; negative predictive value, 67%; accuracy, 87%. We have concluded that the scintigraphic method should be used to confirm the diagnosis of GERD and also recommended as initial investiative procedure. (author)

    Upper gastrointestinal endoscopy and radiologic examination were performed in 101 patients with symptoms strongly suggestive of gastroesophageal reflux (GER) disease. Hiatus hernia (HH) was found in 50 patients diagnosed by radiography or endoscopy, or both, in 22, 19, and 9 patients respectively. Severe endoscopic esophagitis (grades III and IV) was found more often in the patients with HH than in those without. The same was true for the early positive timed acid perfusion tests. Furthermore, the patients with HH more often had reflux by the standard acid reflux test (42 og 50 versus 28 of 51, gastroesophageal scintigraphy (47 of 50 versus 40 of 51; and radiography (20 of 50 versus 2 of 51; than the patients without HH. The results show that severe GER disease can occur without an associated HH and indicate that patients with symptoms of GER disease and associated HH are likely to have a more severe GER disease than those without HH.

    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

    Gastroesophageal reflux disease (GERD) and laryngopharyngeal reflux (LPR) are sibling diseases that are a modern-day plague. Millions of Americans suffer from their sequelae, ranging from subtle annoyances to life-threatening illnesses such as asthma, sleep apnea, and cancer. Indeed, the recognized prevalence of GERD alone has increased threefold throughout the 1990s. Knowledge of the precise etiologies for GERD and LPR is becoming essential for proper treatment. This review focuses on the anatomical, physiological, neurobiological, and cellular aspects of these diseases. By definition, gastroesophageal reflux (GER) is the passage of gastric contents into the esophagus; when excessive and damaging to the esophageal mucosa, GERD results. Reflux that advances to the laryngopharynx and, subsequently, to other regions of the head and neck such as the larynx, oral cavity, nasopharynx, nasal cavity, paranasal sinuses, and even middle ear results in LPR. While GERD has long been identified as a source of esophageal disease, LPR has only recently been implicated in causing head and neck problems. Recent research has identified four anatomical/physiological "barriers" that serve as guardians to prevent the cranial incursion of reflux: the gastroesophageal junction, esophageal motor function and acid clearance, the upper esophageal sphincter, and pharyngeal and laryngeal mucosal resistance. Sequential failure of all four barriers is necessary to produce LPR. While it has become apparent that GER must precede both GERD and LPR, the head and neck distribution of the latter clearly separates these diseases as distinct entities warranting specialized focus and treatment.

  12. Radiologic diagnosis of gastro-oesophageal reflux by means of graded abdominal compression

    Fransson, S.G.; Soekjer, H.; Johansson, K.E.; Tibbling, L.

    The aim of the study was to ascertain whether abdominal compression by a standardized technique increases the reliability of the radiologic diagnosis of gastro-oesophageal reflux. Eighty-eight patients were examined by means of a manometric reflux test, 24-hour measurements of pH and endoscopy. The radiologic examination was performed with and without graded abdominal compression, the patient at the same time turning from side to side. When abdominal compression was included the result of the radiologic examination was positive in 31 patients. In the absence of abdominal compression reflux was detected in 11 of these patients. In one patient reflux was detected only without compression. All these 31 patients had one more test positive and in 27 at least 2 more tests were positive. Another 21 patients had reflux disease as indicated by at least 2 of the 3 other tests. The compression technique seems to yield no false positive responses, and proved to be significantly more reliable than examinations without compression.

    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.

  14. Involvement of autonomic nervous activity changes in gastroesophageal reflux in neonates during sleep and wakefulness.

    Djamal-Dine Djeddi

    Full Text Available BACKGROUND: It has been suggested that disturbed activity of the autonomic nervous system is one of the factors involved in gastroesophageal reflux (GER in adults. We sought to establish whether transient ANS dysfunction (as assessed by heart rate variability is associated with the occurrence of GER events in neonates during sleep and wakefulness. METHODS: Nineteen neonates with suspected GER underwent simultaneous, synchronized 12-hour polysomnography and esophageal multichannel impedance-pH monitoring. We compared changes in HRV parameters during three types of periods (control and prior to and during reflux with respect to the vigilance state. RESULTS: The vigilance state influenced the distribution of GER events (P<0.001, with 53.4% observed during wakefulness, 37.6% observed during active sleep and only 9% observed during quiet sleep. A significant increase in the sympathovagal ratio (+32%, P=0.013 was observed in the period immediately prior to reflux (due to a 15% reduction in parasympathetic activity (P=0.017, relative to the control period. This phenomenon was observed during both wakefulness and active sleep. CONCLUSION: Our results showed that GER events were preceded by a vigilance-state-independent decrease in parasympathetic tone. This suggests that a pre-reflux change in ANS activity is one of the factors contributing to the mechanism of reflux in neonates.

    The possible pathophysiology of the relationship between gastro-esophageal reflux disease and apnea of prematurity has been widely investigated. Various physiological protective reflex responses provide a plausible biological link between gastro-esophageal reflux and apnea of prematurity. It is uncertain whether or not there is a causal relationship between the two diseases. PATIENT'S FINDINGS: Twins were admitted to the neonatal intensive care unit due to feeding problems. Physical examination was normal except for reticulated, blueviolet skin changes. Short apneic attacks occurred on the first day in twin 1 and on the second day in twin 2, and these were initially treated by stimulation and increased ambient O2 concentration. Then, we conducted methylxanthine and continuous positive airway pressure treatment. Laboratory and radiological analysis were normal. As gastro-esophageal reflux disease was thought to be the causes of the treatment-refractory apnea, therapy with gaviscon and domperidon was begun for both cases. Apneic attacks did not recur after gaviscon and domperidon therapy. Pharmacological therapy for gastro-esophageal reflux disease has not definitively been shown to be effective in improving symptoms and hence, should be reserved especially for infants with treatment refractory apnea episodes suspected as being gastro-esophageal reflux in premature infants.

    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. Copyright © 2015 Elsevier Inc. All rights reserved.

    Gastroesophageal reflux (GER) is common in infancy and mainly treated through nonpharmacological interventions. Knowing the early warning signs of GER is important for nursing assessment. Untreated GER can become acute when an infant fails to gain weight and has recurrent, forceful vomiting. Further investigation of gastroesophageal reflux disease (GERD) is indicated when failure to gain weight, irritability, swallowing difficulties, regurgitation, and respiratory complications occur and should trigger referral to pediatric specialists. This article will share information about uncomplicated GER, GERD, and symptoms of these diagnoses, common screening tests, and treatment options. Copyright © 2017 Elsevier Inc. All rights reserved.

    The association of gastroesophageal reflux disease and its pulmonary manifestation is well known however the exact underlying mechanism is unclear. The medical literature is deluged with studies on relationship between Gear and its pulmonary manifestations. The aim of this study was to 1) determine prevalence of GER in children with rLRTI, wheezing and asthma. 2) determine prevalence of asymptomatic respiratory anomalies in children with clinical reflux 3) determine effectiveness of anti-reflux therapy in clinical control of asthma, wheezing and rLRTI. Children were included in the study if they presented either with rLRTI, wheezing, Bronchial asthma or Clinical suspicion of GER without any respiratory symptoms. The GER study comprised esophageal transit, gastroesophageal reflux and lung aspiration studies. Acquisition and processing were according to predetermined protocol. Segmental and global esophageal transit times, GER according to duration of episode and volume of refluxed liquid, Reflux severity, Gastric retention at 30 minutes, Gastric emptying time, Presence of lung aspiration were calculated for each study. All children underwent Barium studies on a separate day. Clinical follow-up was done every 3 months and GER study was repeated every 6 months up to one year. The patient's therapy was determined by local protocols at discretion of clinicians. GER scintigraphy was performed in 43 patients (age range 5 months -12 years). Gastroesophageal reflux of varying degrees was observed in 10 children (23.25%) in all groups. The severity of clinical symptoms was directly related to severity of GER. The direct correlation was found between GER and reflux index. The results of GER scintigraphy were compared with Barium studies and results were found to be superior in terms of sensitivity, specificity and accuracy in detecting disease. It was possible to objectively evaluate and monitor response to therapy after medical treatment in few cases with help of follow

    Continuous distillation column was used for the purification of bioethanol from fermentation of molasses using Saccharomyces cerevisia. Bioethanol produced was at 8.32% (v/v) level. The efficiency of continuous distillation process was evaluated based on reflux ratio, and feed condition. The lab results were validated using COFE simulation Software. The analyses showed that both reflux ratio and feed condition had significant effects on the distillation process. Stages increased from 1.79 to 2.26 as the reflux ratio was decreased from 90% to 45% and the saturated feed produced lower mole fraction of desired product. We concluded that the lower reflux ratio with cold feed condition was suitable for higher mole fraction of top product.

    In this investigation, the author initially made animal experiments to find out: - if and how the gastro-oesophageal reflux in a cardiac insufficiency caused by cardiomyotomy could be proven quantitatively by scintiscanning as often as wanted and how the course of the arising oesophagitis correlated with the findings of the scintiscanning. For the clinical examinations, he referred to patients complaining the reflux difficulties or patients who had had a Balanced Operation because of a reflux disease. The main concern was to clarify the special characteristics and the reliability of reflux scintiscanning and to compare them to conventional methods of radiological and endoscopic reflux diagnostics.

    Gastroesophageal reflux disease (GERD) is the most prevalent gastrointestinal disorder in the United States, and leads to substantial morbidity, though associated mortality is rare. The prevalence of GERD symptoms appeared to increase until 1999. Risk factors for complications of GERD include advanced age, male sex, white race, abdominal obesity, and tobacco use. Most patients with GERD present with heartburn and effortless regurgitation. Coexistent dysphagia is considered an alarm symptom, prompting evaluation. There is substantial overlap between symptoms of GERD and those of eosinophilic esophagitis, functional dyspepsia, and gastroparesis, posing a challenge for patient management.

    Full Text Available In the United States and Europe, gastroesophageal reflux (GER is receiving attention as a potential cause of bronchial asthma. Few Japanese case reports have described this relationship. Therefore, we investigated the effect of omeprazole and cisapride on pulmonary function tests, blood gases and home peak expiratory flow rates (PEFR in six Japanese outpatients with asthma and proven GER. After 8 weeks of treatment, reflux esophagitis had improved in all patients. However, the parameters of pulmonary function showed no change other than a significant post- treatment increase in home PEFR (4.4-27.7% in three patients. These results suggest that anti-reflux (omeprazole and cisapride treatment will produce small improvements in the PEFR in some Japanese asthmatics with GER.

    QUESTION In addition to suffering from nausea and vomiting of pregnancy, which is being treated with antiemetics, some of my pregnant patients complain of heartburn and acid reflux. Should these symptoms also be treated and, if so, which acid-reducing medications are safe for use during pregnancy? ANSWER Increased severity of nausea and vomiting of pregnancy is associated with the presence of heartburn and acid reflux. Antacids, histamine-2 receptor antagonists, and proton pump inhibitors can be used safely during pregnancy, as large studies have been published with no evidence of adverse fetal effects.

  7. Inhibitory Effect of Nasal Intermittent Positive Pressure Ventilation on Gastroesophageal Reflux.

    Directory of Open Access Journals (Sweden)

    Danny Cantin

    Full Text Available Non-invasive intermittent positive pressure ventilation can lead to esophageal insufflations and in turn to gastric distension. The fact that the latter induces transient relaxation of the lower esophageal sphincter implies that it may increase gastroesophageal refluxes. We previously reported that nasal Pressure Support Ventilation (nPSV, contrary to nasal Neurally-Adjusted Ventilatory Assist (nNAVA, triggers active inspiratory laryngeal closure. This suggests that esophageal insufflations are more frequent in nPSV than in nNAVA. The objectives of the present study were to test the hypotheses that: i gastroesophageal refluxes are increased during nPSV compared to both control condition and nNAVA; ii esophageal insufflations occur more frequently during nPSV than nNAVA. Polysomnographic recordings and esophageal multichannel intraluminal impedance pHmetry were performed in nine chronically instrumented newborn lambs to study gastroesophageal refluxes, esophageal insufflations, states of alertness, laryngeal closure and respiration. Recordings were repeated without sedation in control condition, nPSV (15/4 cmH2O and nNAVA (~ 15/4 cmH2O. The number of gastroesophageal refluxes recorded over six hours, expressed as median (interquartile range, decreased during both nPSV (1 (0, 3 and nNAVA [1 (0, 3] compared to control condition (5 (3, 10, (p < 0.05. Meanwhile, the esophageal insufflation index did not differ between nPSV (40 (11, 61 h-1 and nNAVA (10 (9, 56 h-1 (p = 0.8. In conclusion, nPSV and nNAVA similarly inhibit gastroesophageal refluxes in healthy newborn lambs at pressures that do not lead to gastric distension. In addition, the occurrence of esophageal insufflations is not significantly different between nPSV and nNAVA. The strong inhibitory effect of nIPPV on gastroesophageal refluxes appears identical to that reported with nasal continuous positive airway pressure.

    Laparoscopic sleeve gastrectomy (LSG) has gained significant popularity in the USA, and consequently resulted in patients experiencing new-onset gastroesophageal reflux disease (GERD) following this bariatric procedure. Patients with GERD refractory to medical therapy present a more challenging situation limiting the surgical options to further treat the de novo GERD symptoms since the gastric fundus to perform a fundoplication is no longer an option. The aim of this study is to determine if the LINX® magnetic sphincter augmentation system is a safe and effective option for patients with new gastroesophageal reflux disease following laparoscopic sleeve gastrectomy. This study was conducted at the University Medical Center. This is a retrospective review of seven consecutive patients who had a laparoscopic LINX® magnetic sphincter device placement for patients with refractory gastroesophageal reflux disease after laparoscopic sleeve gastrectomy between July 2014 and April 2015. All patients were noted to have self-reported greatly improved gastroesophageal reflux symptoms 2-4 weeks after their procedure. They were all noted to have statistically significant improved severity and frequency of their reflux, regurgitation, epigastric pain, sensation of fullness, dysphagia, and cough symptoms in their postoperative GERD symptoms compared with their preoperative evaluation. This is the first reported pilot case series, illustrating that the LINX® device is a safe and effective option in patients with de novo refractory gastroesophageal reflux disease after a laparoscopic sleeve gastrectomy despite appropriate weight loss.

    Reflux of bile and digestive enzymes from the small bowel and duodenum into stomach has been observed in patients with various gastroduodenal diseases. Tc-99m iminodiacetic acid derivatives hepatobiliary scan has been used as a noninvasive method to detect duodenogastric reflux. Sometimes, gastric reflux can be observed incidentally on routine Tc-99m DISA hepatobiliary scintigraphy. To evaluate the clinical meaning of gastric reflux on routine Tc-99m DISIDA hepatobiliary scan, we analyzed 36 patients showed gastric reflux incidentally on the routine Tc-99m-DISIDA hepatobiliary scintigraphy from December 1991 to June 1995 in Chungnam National University Hospital. The results were as follows: 1) The gastric reflux was observed in 2.3% of 1,553 cases of routine Tc-99m DISIDA Hepatobiliary scintigraphy for 43 months. 2) Nineteen percent of patients with gastric reflux had the past medical history of operations on stomach or biliary system. And that history was more prevalent in patients with reflux than those without reflux, significantly (p<0.01). 3) On fiberoptic gastroduodenpscopic examination, 87% of the patients with gastric reflux had the gastroduodenal diseases such as gastritis, gastric ulcer, duodenal ulcer, gastric cancer, duodenal cancer and ampullary diverticulosis. We thought that the gastric reflux can be observed considerably in patients without any operation history on stomach or duodenum, although the operation history is more prevalent in patients with gastric reflux than those without reflux, significantly and most of patients with gastric reflux on routine Tc-99m DISIDA scan has various gastroduodenal diseases.

    The joint hypermobility syndrome (JHS) is a common non-inflammatory connective tissue disorder which frequently co-exists with postural tachycardia syndrome (PoTS), a form of orthostatic intolerance. Gastrointestinal symptoms and dysmotility have been reported in PoTS. Dysphagia and reflux are common symptoms in JHS, yet no studies have examined the physiological mechanism for these, subdivided by PoTS status. Thirty patients (28 female, ages: 18-62) with JHS and symptoms of reflux (n=28) ± dysphagia (n=25), underwent high-resolution manometry and 24 hour pH-impedance monitoring after questionnaire-based symptom assessment. Esophageal physiology parameters were examined in JHS, subdivided by PoTS status. Fifty-three percent of JHS patients with reflux symptoms had pathological acid reflux, 21% had reflux hypersensitivity, and 25% had functional heartburn. Acid exposure was more likely to be increased in the recumbent than upright position (64% vs 43%). The prevalence of hypotensive lower esophageal sphincter (33%) and hiatus hernia (33%) was low. Forty percent of patients with dysphagia had minor disorders of motility, 60% had functional dysphagia. Eighteen (60%) patients had coexistent PoTS-they had significantly higher dysphagia (21 vs 11.5, P=.04) and reflux scores (24.5 vs 16.5, P=.05), and double the prevalence of pathological acid reflux (64% vs 36%, P=.1) and esophageal dysmotility (50% vs 25%, P=.2) though this was not significant. A large proportion of JHS patients with esophageal symptoms have true reflux-related symptoms or mild esophageal hypomotility, and this is more likely if they have PoTS. © 2017 John Wiley & Sons Ltd.

    There have been no studies investigating the distribution of abnormal gastroesophageal flap valve (GEFV) among patients with dyspepsia, non-erosive reflux disease (NERD), and reflux esophagitis (RE) in the same set of patients. The aims of this study are to investigate (1) the association between GEFV and gastroesophageal reflux disease questionnaire (GERDQ) score, and (2) the distribution of abnormal GEFV in Vietnamese patients presenting with upper gastrointestinal symptoms. Three hundred and thirty-one patients recruited in this prospective cross-sectional study were classified into 3 groups: reflux esophagitis (RE), non-erosive reflux disease (NERD) (GERDQ score ≥ 8, no endoscopic mucosal injury), and dyspepsia (GERDQ score < 8, no endoscopic mucosal injury). The GEFV was graded endoscopically according to the Hill classification. GEFV grades I and II were regarded as normal, while grades III and IV were regarded as abnormal GEFV. There were 215 (65.0%) patients with dyspepsia, 55 (16.6%) patients with NERD, and 61 (18.4%) patients with RE. Abnormal GEFV was an independent risk factor for GERD (OR, 2.93; CI 95%, 1.76-4.88) and RE (OR, 3.41; CI 95%, 1.78-6.53). The mean GERDQ score of patients with abnormal GEFV was significantly higher than that of patients with normal GEFV (5.7 ± 2.4 vs 4.9 ± 2.7, P = 0.011). The prevalence of abnormal GEFV gradually increased in patients with dyspepsia (27.4%), NERD (43.6%), grade A RE (56.8%), and grades B/C RE (80.0%) ( P < 0.001). Abnormal GEFV was significantly associated with high GERDQ score. Its prevalence gradually increased in patients with dyspepsia, NERD, and RE, respectively.

    To investigate the relationship between use of asthma medication and nitrates and risk of reflux oesophagitis, Barrett's oesophagus and oesophageal adenocarcinoma. Data were collected on use of asthma medication and nitrates at least 1 year before interview from patients with reflux oesophagitis, Barrett's oesophagus and oesophageal adenocarcinoma. Associations between use of asthma medications and nitrates and the risk of reflux oesophagitis, Barrett's oesophagus and oesophageal adenocarcinoma were estimated using multiple logistic regression. Nine hundred and forty-one subjects were recruited: 230 reflux oesophagitis, 224 Barrett's oesophagus, 227 oesophageal adenocarcinoma patients and 260 population controls. Barrett's oesophagus patients were more likely than controls to have had a diagnosis of asthma (odds ratio 2.15, 95% confidence interval 1.15-4.03) and to have used asthma medications (odds ratio 2.13, 95% confidence interval 1.09-4.16). No significant associations were observed between use of asthma medication or nitrates and reflux oesophagitis or oesophageal adenocarcinoma. Gastro-oesophageal reflux symptoms appear to confound the association between asthma medication use and Barrett's oesophagus. However, it is possible that asthma medications may increase the risk of Barrett's oesophagus by other mechanisms.

    With wide application of antireflux surgery, reoperations for failed fundoplications are increasingly seen. This study was undertaken to document outcomes after reoperative fundoplications. Sixty-four patients, 26 men and 38 women, of average age 55 years+/-15.6 (SD), underwent reoperative antireflux surgery between 1992 and 2003. Fundoplication prior to reoperation had been undertaken via celiotomy in 27 and laparoscopically in 37. Both before and after reoperative antireflux surgery, patients scored their reflux and dysphagia on a Likert Scale (0 = none, 10 = continuous). Reoperation was undertaken because of dysphagia in 16 per cent, recurrent reflux in 52 per cent (median DeMeester Score 52), or both in 27 per cent. Failure leading to reoperation was due to hiatal failure in 28 per cent, wrap failure in 19 per cent, both in 33 per cent, and slipped Nissen fundoplication in 20 per cent. Laparoscopic reoperations were completed in 49 of 54 patients (91%); 15 had reoperations undertaken via celiotomy. Eighty-eight per cent of reoperations were Nissen fundoplications. With reoperation, Dysphagia Scores improved from 9.5+/-0.7 to 2.6+/-2.8, and Reflux Scores improved from 9.1+/-1.4 to 1.8+/-2.7. Seventy-nine per cent of patients with reflux prior to reoperation, 100 per cent with dysphagia, and 74 per cent with both noted excellent or good outcomes after reoperation. We conclude that failure after fundoplication occurs. Reoperations reduce the severity of dysphagia and reflux, thus salvaging excellent and good outcomes in most. Laparoscopic reoperations are generally possible. Reoperative fundoplications are effective treatment for dysphagia and recurrent gastroesophageal reflux, and their application is encouraged.

    2010-08-01

    Refractory gastro-esophageal reflux disease (GERD), defined as persistent symptoms despite proton pump inhibitor (PPI) therapy, is an increasingly prevalent condition and is becoming a major challenge for the clinician. Since non-acidic reflux may be associated with symptoms persisting during PPI treatment, the lower esophageal sphincter (LES), the most important barrier protecting against reflux, has become an important target for the treatment of (refractory) GERD. Preclinical research has identified several receptors that are involved in the control of transient lower esophageal sphincter relaxations (TLESRs), the predominant mechanism of both acid and non-acidic reflux events, and several drugs have now been tested in humans. The GABA(B) agonist baclofen has demonstrated to effectively reduce the rate of TLESRs and the amount of reflux in both GERD patients and healthy volunteers. Nevertheless, the occurrence of central side effects limits its clinical use for the treatment of GERD. Several analogues are being developed to overcome this limitation and have shown promising results. Additionally, metabotropic glutamate receptor 5 (mGluR5) receptor antagonists have shown to reduce both acid and non-acidic reflux in GERD patients and several molecules are currently being evaluated. Although CB(1) antagonists have been shown to reduce TLESRs, they are also associated with central side effects, limiting their clinical applicability. Despite the identification of several potentially interesting drugs, the main challenge for the future remains the reduction of central side effects. Moreover, future studies will need to demonstrate the efficacy of these treatments in patients with refractory GERD.

    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. Copyright © 2015.

    Gastro-oesophageal reflux disease (GERD) adversely impacts on sleep, but the mechanism remains unclear. To review the literature concerning gastro-oesophageal reflux during the sleep period, with particular reference to the sleep/awake state at reflux onset. Studies identified by systematic literature searches were assessed. Overall patterns of reflux during the sleep period show consistently that oesophageal acid clearance is slower, and reflux frequency and oesophageal acid exposure are higher in patients with GERD than in healthy individuals. Of the 17 mechanistic studies identified by the searches, 15 reported that a minority of reflux episodes occurred during stable sleep, but the prevailing sleep state at the onset of reflux in these studies remains unclear owing to insufficient temporal resolution of recording or analysis methods. Two studies, in healthy individuals and patients with GERD, analysed sleep and pH with adequate resolution for temporal alignment of sleep state and the onset of reflux: all 232 sleep period reflux episodes evaluated occurred during arousals from sleep lasting less than 15 s or during longer duration awakenings. Six mechanistic studies found that transient lower oesophageal sphincter relaxations were the most common mechanism of sleep period reflux. Contrary to the prevailing view, subjective impairment of sleep in GERD is unlikely to be due to the occurrence of reflux during stable sleep, but could result from slow clearance of acid reflux that occurs during arousals or awakenings from sleep. Definitive studies are needed on the sleep/awake state at reflux onset across the full GERD spectrum. © 2013 John Wiley & Sons Ltd.

    Prader-Willi syndrome (PWS) is the most common genetic human obesity syndrome and is characterized by hypotonia, endocrine disturbances, hyperphagia, obesity and mild mental retardation. Oral abnormalities, such as decreased salivary flow rates and extreme tooth wear, have also been described. Studies have shown a significant increase in reflux symptoms in individuals with obstuctive sleep apnoea syndrome and increased BMI, both of which are typical findings in PWS. Gastro-oesophageal reflux disease (GORD) has been identified in some individuals with PWS and is a significant intrinsic factor in dental tooth wear. The aim of this study was therefore to estimate the prevalence of GORD in adults and children and to evaluate a possible correlation between GORD and tooth wear in adults with PWS. They were all registered at the TAKO-centre. Twenty-nine individuals, 17 adults with a mean age of 32.6 years (range 18-48) and 12 children with a mean age of 8.8 years (range 3-17), agreed to undergo 24-hour oesophageal pH monitoring, and 90% of those enrolled managed to complete the examination. Four children and eleven adults were diagnosed with pathological gastro-oesophageal reflux, which is defined as acid exposure (pH less than 4) more than 3.6 or 4.3 percent of the time, respectively. Manometry performed in the adult group showed a pathologically high lower oesophageal sphincter pressure in four of the five individuals who had normal oesophageal pH values (pH under 4 less than 4.3% of the time). The two groups (reflux and non-reflux) were well balanced according to BMI, genotype, tooth grinding and hyposalivation. However, twice as many individuals in the reflux group as in the non-reflux group reported high consumption of acidic foods and drinks. Increased tooth wear was significantly correlated with GORD in the two groups (reflux n=6 and non-reflux n=6). The prevalence of gastro-oesophageal reflux is high in individuals with PWS. Tooth wear was strongly associated with

    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 heartburn preceded by acid reflux in diurnal (39%vs 9%; P 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.

  8. Respiratory and laryngeal symptoms secondary to gastro-oesophageal reflux

    2011-01-01

    Gastro-oesophageal reflux may cause a range of laryngeal and respiratory symptoms. Mechanisms responsible include the proximal migration of gastric refluxate beyond the upper oesophageal sphincter causing direct irritation of the larynx and lower airway. Alternatively, refluxate entering the distal oesophagus alone may stimulate oesophageal sensory nerves and indirectly activate airway reflexes such as cough and bronchospasm. Recognising reflux as a cause for these extraoesophageal symptoms can be difficult as many patients do not have typical oesophageal symptoms (eg, heartburn) and clinical findings on laryngoscopy are not very specific. Acid suppression remains an effective treatment in the majority of patients but there is growing appreciation of the need to consider and treat non-acid and volume reflux. New opinions about the role of existing medical and surgical (laparoscopic techniques) treatment are emerging and a number of novel anti-reflux treatments are under development. PMID:28839612

  9. Gastroesophageal Reflux and Idiopathic Pulmonary Fibrosis: A Review

    Directory of Open Access Journals (Sweden)

    Ahmed Fahim

    2011-01-01

    Full Text Available The histological counterpart of idiopathic pulmonary fibrosis is usual interstitial pneumonia, in which areas of fibrosis of various ages are interspersed with normal lung. This pattern could be explained by repeated episodes of lung injury followed by abnormal wound healing responses. The cause of the initiating alveolar epithelial injury is unknown, but postulated mechanisms include immunological, microbial, or chemical injury, including aspirated gastric refluxate. Reflux is promoted by low basal pressure in the lower oesophageal sphincter and frequent relaxations, potentiated by hiatus hernia or oesophageal dysmotility. In susceptible individuals, repeated microaspiration of gastric refluxate may contribute to the pathogenesis of IPF. Microaspiration of nonacid or gaseous refluxate is poorly detected by current tests for gastroesophageal reflux which were developed for investigating oesophageal symptoms. Further studies using pharyngeal pH probes, high-resolution impedance manometry, and measurement of pepsin in the lung should clarify the impact of reflux and microaspiration in the pathogenesis of IPF.

    Gastroesophageal reflux disease (GERD) is a common chronic disorder that is associated with a huge economic burden in the western countries and significantly decreased quality of life. This review focuses on the various multicultural issues in the epidemiology, pathophysiology, diagnosis, and treatment of GERD. The prevalence of GERD appears to be highest in North America and Europe, whereas epidemiologic data from the Indian subcontinent, Africa, South America, and the Middle East are sparse. A limited number of studies have elucidated ethnic differences in GERD in multiracial populations. African Americans and Asians appear to be at a lower risk for the development of complicated GERD including Barrett's esophagus (BE). Whether the pathophysiology of GERD differs among different populations remains to be answered satisfactorily. It appears that most of the factors involved in the pathogenesis of GERD, as described in western populations, are present in Asians but at a lower scale. The current recommendations for the management of GERD by the American College of Gastroenterology may not meet the need for different ethnic groups or for different geographic regions. Recognition of language barriers in understanding the common terms used to describe reflux symptoms should be borne in mind while treating GERD patients with different ethnic backgrounds. In addition, a universally accepted definition for treatment success in GERD patients is lacking. Given the negative impact on health-related quality of life, significant cost ramifications, and increased risk for BE and esophageal adenocarcinoma, the study of multicultural issues in GERD should be considered.

    Full Text Available Introduction: The study was conducted to determine the association of Helicobactor pylori with endoscopic and histological parameters of gastroesophageal reflux disease (GERD. Materials and Methods: A cross-sectional study was undertaken. A total of 79 patients were evaluated prospectively in the endoscopic unit of a gastroenterology department for symptoms compatible with GERD. In all cases, routine endoscopy and Los Angeles grading of GERD were performed. In each subject, biopsies were taken from 3 cm above the squamocolumnar junction and from the antrum and assessed histologically. Results: Majority of the patients presented with complaints of heartburn (84.8% and regurgitation (75.9%. Nonerosive reflux disease was present in only five patients. Endoscopically, the remaining 74 cases were graded as follows: 25 had GERD A, 10 had GERD B, 35 had features of Barrett's esophagus, and 4 had miscellaneous findings. H. pylori positivity was present in 33.3% of patients with GERD A and 4.8% of those with GERD B. Majority of the histological parameters such as elongation of lamina propria papillae, intraepithelial inflammatory infiltrate, ballooning degeneration, lack of surface maturation, and dilatation and congestion of lamina propria capillaries did not show statistically significant association with H. pylori. The overall H. pylori prevalence was found to be 26.58% (21/79. Conclusion: On endoscopy, with the increased GERD severity, H. pylori incidence decreased. H. pylori was found to have no significant association with majority of the histological parameters.

    The purpose of this study was to investigate the impact of gastroesophageal reflux disease (GERD) on dental erosion (DE) in children and analyze the association between dental erosion and diet, oral hygiene, and sociodemographic characteristics. This case-control study encompassed 43 two- to 14-year-olds diagnosed positive for GERD by the 24-hour pH monitoring, paired by age group with 136 healthy controls, in Belo Horizonte, Minas Gerais, Brazil. DE was assessed by one calibrated examiner using the O'Sullivan index. A questionnaire was self-administered by parents collecting information regarding sociodemographics, oral hygiene, and dietary habits. Dental erosion experience was compared between the groups, and a stratified analysis was performed (PDental erosion was diagnosed in 10.6 percent (N equals 19) of all the children; 25.6 percent (N equals 11) of GERD children and 5.9 percent (N equals eight) of children without GERD, P=0.001). Dental erosion was not associated with dietary consumption or sociodemographic characteristics in both groups (P≥0.05). Children who used adult toothpaste had a 5.79 higher chance of having dental erosion in the group with GERD. Children diagnosed with gastroesophageal reflux disease were at an increased risk of having dental erosion when compared to healthy subjects; among the GERD children, dental erosion was associated with the use of adult toothpaste.

    Objectives To investigate the effects of Helicobacter pylori infection and its eradication on heartburn and gastro-oesophageal reflux. Design Cross sectional study, followed by a randomised placebo controlled trial. Setting Seven general practices in Bristol, England. Participants 10 537 people, aged 20-59 years, with and without H pylori infection (determined by the 13C-urea breath test). Main outcome measures Prevalence of heartburn and gastro-oesophageal acid reflux at baseline and two years after treatment to eradicate H pylori infection. Results At baseline, H pylori infection was associated with increased prevalence of heartburn (odds ratio 1.14, 95% confidence interval 1.05 to 1.23) but not reflux (1.05, 0.97 to 1.14). In participants with H pylori infection, active treatment had no effect on the overall prevalence of heartburn (0.99, 0.88 to 1.12) or reflux (1.04, 0.91 to 1.19) and did not improve pre-existing symptoms of heartburn or reflux. Conclusions H pylori infection is associated with a slightly increased prevalence of heartburn but not reflux. Treatment to eradicate H pylori has no net benefit in patients with heartburn or gastro-oesophageal reflux. PMID:15126313

    Background: Prevalence of gastroesophageal reflux disease (GERD) has increased in the last decades, and it is now one of the most common chronic and recurrent diseases. The present study aimed at determining the frequency of gender (sex) and age in Iranian patients with GERD symptoms. Methods: In this study, 803 patients aged 11 to 84 years, with erosive and nonerosive gastroesophageal reflux diseases, based on the questionnaire and esophagogastroduodenoscopy findings, participated. The female group was compared with the male group with respect to age, symptoms, esophageal injury, and hiatus hernia. Results: Of the 803 participants, 60.5% (n= 486) were female, and 69.2% (n= 555) were younger than 50 years. Of those patients older than 50 years, 32.8% (n= 81) were female. Moreover, 31.0% (n= 249) of the patients had erosive esophagitis (ERD), and 69.0% (n= 254) had normal esophageal mucosa (NERD).The female to male ratio was 1/1.06 and 1.94/1 in ERD and NERD patients, respectively. Hiatal hernia was more prevalent in females than in males. Conclusion: Nonerosive reflux disease, as a gastroesophageal reflux disease (GERD), was more common in females than in males. GERD became more prevalent with increase in age. Gender and hiatal hernias were 2 potential risk factors of GERD.

    The macroscopic appearance of the normal squamocolumnar junction (SCJ) is often described as serrated with short projections of columnar mucosa that extend into the esophagus. As studies of the normal SCJ are sparse, the aim of this study was to test the hypothesis that the normal SCJ is even and that irregularities are manifestations of acid reflux. Fifty asymptomatic subjects and 149 patients with symptoms suggestive of gastroesophageal reflux disease underwent endoscopy and 48-h pH monitoring with a pH electrode positioned immediately above the SCJ. The shape of the SCJ was assessed according to the Z-line appearance classification and correlated with clinical characteristics and the degree of esophageal acid exposure in the most distal esophagus. Even SCJs without irregularities were significantly more common in asymptomatic subjects compared with patients (50% versus 10%, p acid exposure in individuals with an even SCJ was within normal limits. With increasing degree of irregularity of the SCJ, the frequency and duration of reflux episodes, the degree of distal esophageal acid exposure, and the prevalence of abnormal acid exposure increased progressively and significantly. The shape of the normal SCJ is even and also minimal irregularities are a consequence of acid reflux, likely due to the formation of small areas of metaplastic columnar mucosa.

  16. Pathophysiology of gastro-esophageal reflux disease: a role for mucosa integrity?

    Farré, R

    2013-10-01

    Gastro-esophageal reflux disease (GERD) is very prevalent and has a high burden on health security system costs. Nevertheless, pathophysiology is complex and not well-understood. Several mechanisms have been proposed: decreased salivation, impaired esophageal clearance, decreased lower esophageal sphincter pressure resting tone, presence of hiatal hernia, increased number of transient lower esophageal sphincter relaxations (TLESRs), increased acid, and pepsin secretion, pyloric incompetence provoking duodeno-gastro-esophageal reflux of bile acids and trypsin. Independent of the relevance of each mechanism, the ultimate phenomenon is that mucosal epithelium is exposed for a longer time to agents as acid and pepsin or is in contact to luminal agents not commonly present in gastric refluxate as trypsin or bile acids. This leads to a visible damage of the epithelium (erosive esophagitis -EE) or impairing mucosal integrity without any sign of macroscopic alteration as occurs in non-erosive reflux disease (NERD). Luminal factors are not the only responsible for such impairment; more recent data indicate that endogenous factors may also play a role. This review will update the most recent findings on the putative pathophysiological mechanisms and specially will focus on the role of esophageal mucosal integrity in GERD. Methodologies used for the evaluation of mucosal integrity, its relevance in EE and NERD, its involvement in symptoms perception and the effect of luminal and endogenous factors will be discussed. © 2013 John Wiley & Sons Ltd.

    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.

    Full Text Available Gastro-esophageal reflux (GER is common in infants and children and has a varied clinical presentation: from infants with innocent regurgitation to infants and children with severe esophageal and extra-esophageal complications that define pathological gastro-esophageal reflux disease (GERD. Although the pathophysiology is similar to that of adults, symptoms of GERD in infants and children are often distinct from classic ones such as heartburn. The passage of gastric contents into the esophagus is a normal phenomenon occurring many times a day both in adults and children, but, in infants, several factors contribute to exacerbate this phenomenon, including a liquid milk-based diet, recumbent position and both structural and functional immaturity of the gastro-esophageal junction. This article focuses on the presentation, diagnosis and treatment of GERD that occurs in infants and children, based on available and current guidelines.

    Twenty-five infants and children with proved gastroesophageal reflux were studied by radionuclide gastroesophagography to determine its sensitivity in detecting reflux. Patients swallowed an inert radiotracer (Tc-99m sulfur colloid) and gamma camera images of the stomach and esophagus were made with and without abdominal pressure. The test was easy to perform and was well tolerated. Reflux was demonstrated in 20 patients (80%); this compared favorably with barium gastroesophagography

    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.

    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

    Upper gastrointestinal endoscopy and radiologic examination were performed in 101 patients with symptoms strongly suggestive of gastroesophageal reflux (GER) disease. Hiatus hernia (HH) was found in 50 patients diagnosed by radiography or endoscopy, or both, in 22, 19, and 9 patients respectively. Severe endoscopic esophagitis (grades III and IV) was found more often (p<0.05) in the patients with HH than in those without. The same was true for the early positive timed acid perfusion tests (p<0.02). Furthermore, the patients with HH more often had reflux by the standard acid reflux test (42 og 50 versus 28 of 51; p<0.01), gastroesophageal scintigraphy (47 of 50 versus 40 of 51; p<0.05), and radiography (20 of 50 versus 2 of 51; p<0.001) than the patients without HH. The results show that severe GER disease can occur without an associated HH and indicate that patients with symptoms of GER disease and associated HH are likely to have a more severe GER disease than those without HH

  5. Laryngopharyngeal Reflux: Diagnosis, Treatment, and Latest Research

    Full Text Available Introduction Laryngopharyngeal reflux (LPR is a highly prevalent disease and commonly encountered in the otolaryngologist's office. Objective To review the literature on the diagnosis and treatment of LPR. Data Synthesis LPR is associated with symptoms of laryngeal irritation such as throat clearing, coughing, and hoarseness. The main diagnostic methods currently used are laryngoscopy and pH monitoring. The most common laryngoscopic signs are redness and swelling of the throat. However, these findings are not specific of LPR and may be related to other causes or can even be found in healthy individuals. Furthermore, the role of pH monitoring in the diagnosis of LPR is controversial. A therapeutic trial with proton pump inhibitors (PPIs has been suggested to be cost-effective and useful for the diagnosis of LPR. However, the recommendations of PPI therapy for patients with a suspicion of LPR are based on the results of uncontrolled studies, and high placebo response rates suggest a much more complex and multifactorial pathophysiology of LPR than simple acid reflux. Molecular studies have tried to identify biomarkers of reflux such as interleukins, carbonic anhydrase, E-cadherin, and mucin. Conclusion Laryngoscopy and pH monitoring have failed as reliable tests for the diagnosis of LPR. Empirical therapy with PPIs is widely accepted as a diagnostic test and for the treatment of LPR. However, further research is needed to develop a definitive diagnostic test for LPR.

    In order to evaluate the possibility of detecting intra-renal reflux (IRR) with a more sensitive procedure, 48 children with recurrent urinary tract infections underwent intravenous urography (IVU) and voiding cystourethrogram (VCU) using a solution containing contrast medium and sup(99m)Tc-sulfur colloid particles which are known to persist in the renal parenchyma for a long time. Scintigraphic images were taken at 5 and 20 hours after VCU. 18 children had no vesico-ureteral reflux, 11 showed unilateral and 19 bilateral VUR, which was therefore present in 49 renal units. Among the 49 renal refluxing units (RRUs) IRR was detected radiologically in 8; of these isotopic activity in the renal area was present in all 6 RRUs who were examined at 20 hours. Of the remaining 41 RRUs with no radiologically detectable IRR 24 were evaluated at 20 hours and 5 (21%) showed renal radioactivity. Renal scars were significantly more frequent in kidneys with radioisotopic activity at 20 hours. The results of this study indicate that radionuclide cystography using sup(99m)Tc-sulfur colloid is a reliable procedure for demonstrating IRR, and to this end is more sensitive than X-ray VCU. Radionuclide cystography with sulfur colloid particles should therefore be considered a simple and useful complementary procedure, which is more sensitive than X-ray VCU in the diagnosis and follow-up of IRR

    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.

    Full Text Available Background: The association of gastro-esophageal reflux (GER with a wide variety of pulmonary disorders was recognized. We aimed to evaluate the effect of GER-induced esophagitis on airway hyper-reactivity (AHR in patients and the response to treatment. Materials and Methods: In this cohort study, 30 patients attending the gastrointestinal clinic of a university hospital with acid reflux symptoms were included. All patients were evaluated endoscopically and divided into case group with esophagitis and control group without any evidence of esophagitis. Spirometry and methacholine test were done in all patients before and after treatment of GER with pantoprazole 40 mg daily for six months. Results: There was a significant difference in the rate of positive methacholine test between the cases (40% and the controls (6.7% prior to anti-acid therapy (P < 0.0001. After six months of treatment, the frequency of positive methacholine test diminished from 40 to 13.3% in the case group (P < 0.05 but did not change in the controls (P = 0.15. Conclusion: The presence of esophagitis due to GER would increase the AHR and treatment with pantoperazole would decrease AHR in patients with proved esophagitis and no previous history of asthma after six months.

    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). 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. 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. 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). 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.

    Guidelines recommend that patients with gastro-oesophageal reflux disease are adequately treated with acid-suppressive therapy before undergoing anti-reflux surgery. Little is known of the use of acid-suppressive drugs before anti-reflux surgery. To determine the use of proton pump inhibitors and H2 -receptor antagonists in the year before anti-reflux surgery. A nationwide retrospective study of all patients aged ≥18 undergoing first-time anti-reflux surgery in Denmark during 2000-2012 using data from three different sources: the Danish National Register of Patients, the Danish National Prescription Register, and the Danish Person Register. The study population thus included 2922 patients (median age: 48 years, 55.7% male). The annual proportion of patients redeeming ≥180 DDD of acid-suppressive therapy increased from 17.0% 5 years before anti-reflux surgery to 64.9% 1 year before. The probability for inadequate dosing 1 year before surgery (reflux surgery, as a high proportion of patients receive inadequate dosing of acid-suppressive therapy prior to the operation. © 2015 John Wiley & Sons Ltd.

  11. Helicobacter pylori eradication and reflux disease onset: did gastric acid get "crazy"?

    Gastroesophageal reflux disease (GORD) is highly prevalent in the general population. In the last decade, a potential relationship between Helicobacter pylori (H. pylori) eradication and GORD onset has been claimed. The main putative mechanism is the gastric acid hypersecretion that develops after bacterial cure in those patients with corpus-predominant gastritis. We performed a critical reappraisal of the intricate pathogenesis and clinical data available in this field. Oesophagitis onset after H. pylori eradication in duodenal ulcer patients has been ascribed to a gastric acid hypersecretion, which could develop following body gastritis healing. However, the absence of an acid hypersecretive status in these patients is documented by both pathophysiology and clinical studies. Indeed, duodenal ulcer recurrence is virtually abolished following H. pylori eradication. In addition, intra-oesophageal pH recording studies failed to demonstrated increased acid reflux following bacterial eradication. Moreover, oesophageal manometric studies suggest that H. pylori eradication would reduce--rather than favor--acid reflux into the oesophagus. Finally, data of clinical studies would suggest that H. pylori eradication is not significantly associated with either reflux symptoms or erosive oesophagitis onset, some data suggesting also an advantage in curing the infection when oesophagitis is already present. Therefore, the legend of "crazy acid" remains--as all the others--a fascinating, but imaginary tale.

  12. Diagnosis and treatment of patients with nonacid gastroesophageal reflux-induced chronic cough

    Full Text Available Gastroesophageal reflux (GER is one of the most common causes of chronic cough, and chronic cough due to GER represents a subtype of GER-related diseases. Gastroesophageal reflux-induced chronic cough (GERC can be divided into two subgroups based on the pH of the GER. Nonacid GERC is less common than acid GERC, and its diagnosis and treatment strategy have not been standardized. However, nonacid GERC usually presents with its unique set of characteristics and features upon diagnosis and treatment in the clinic. Although the underlying molecular mechanism of nonacid GERC is not fully understood, it is considered to be associated with reflux theory, reflex theory and airway hypersensitivity. Multi-channel intraluminal impedance combined with pH monitoring is a promising new technique that can detect both acid and nonacid reflux, and our findings as well as those of others have shown its usefulness in diagnosing nonacid GERC. Development of new diagnostic techniques has led to an increased rate of nonacid GERC diagnosis. We summarize our experience in the diagnosis and treatment of nonacid GERC and provide a guide for future therapeutic approaches.

    When gastro-oesophageal reflux is causing symptoms or lesions in the oesophagus, this is referred to as gastro-oesophageal reflux disease (GERD). GERD can manifest itself through typical symptoms (heartburn, regurgitation) or may lead to extra-oesophageal symptoms. Extra-oesophageal manifestations of GERD gained increasing attention over the last decade, especially respiratory disorders, because of the prevalent co-occurrence with GERD. The role of GERD in the pathogenesis of respiratory disorders has become a topic of intense discussion. To provide an overview of the current knowledge on the role of GERD in asthma and chronic obstructive pulmonary disease (COPD). PubMed was searched for relevant articles using the keywords: GERD, asthma, COPD, prevalence, treatment. Case reports were excluded, only English language articles were considered. Estimates for the prevalence of GERD in asthma range from 30% to 90%, compared to an average of 24% in controls. In COPD patients, the prevalence of GERD ranges from 19% to 78% compared to an average of 18% in controls. These data indicate an increased prevalence of GERD in patients with asthma and COPD, although causality is not established and GERD treatment yielded inconsistent effects. Literature supports GERD as a risk factor for COPD-exacerbations and a predictor of the 'frequent-exacerbator'-phenotype. Despite the high prevalence of GERD in asthma and COPD, a causal link is lacking. The results of anti-reflux therapy on pulmonary outcome are inconsistent and contradictory. Future studies will need to identify subgroups of asthmatics and COPD patients that may benefit from anti-reflux therapy (nocturnal or silent reflux). © 2017 John Wiley & Sons Ltd.

    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.

    The aim of this work was to study the correlation between the reflux timing and the presence of esophagitis, an inconstant but serious complication of gastro-esophageal reflux (GER). The hypothesis was that reflux occurring late after meal can be incriminated more than early reflux in esophagitis genesis. 32 children with GER (mean age = 10.5 months, 2 to 30 months) had esophagoscopy and scintigraphy in the same week. The children were classified in two groups according to esophagoscopy: group 1 (n = 18) no esophagitis, group 2 (n = 14) esophaqgitis. The scintigraphy involved the ingestion of 0.5 mCi Tc-99m sulfur colloid milk mixture, followed by esophageal and gastric activity recording (one image per minute for 1 hour). The reflux was assessed from contrast enhanced images and esophageal time activity curves. Reflux intensity was quantitated by reflux index (Re). Mean reflux time was calculated as the mean esophageal activity peaks time (t-bar). Finally a composite parameter was calculated as the mean reflux time weighted by the relative intensity of each reflux peak (t-barw). Re was not found to be different between the two groups. t-bar was significantly higher in group 2: t-bar = 29.6 +- 3.0 mn (mean +- SD) than in group 1: t-bar = 24.5 +- 6.8 mn; rho <0.02. The difference between the two groups was enhanced by intensity weighting: group 1: t-barw = 16.6 +- 6.3 mn, group 2: t-barw = 33.5 +- 7.1 mn rho <0.001. t-barw value was not correlated to esophagitis grade. These results suggest that late reflux is more likely responsible of esophagitis

    Supraesophageal reflux of gastric contents can contribute to perennial nasopharyngitis, cough, and asthma. However, effective treatment strategies for supraesophageal reflux disease (SERD) remain inadequately defined. The purpose of this study is to assess the prevalence and timing of SERD and to investigate the efficacy of head-of-bed elevation in its treatment. A retrospective chart review of patients seen at Scripps Clinic Division of Allergy, Asthma and Immunology was performed who had undergone overnight nasopharyngeal pH monitoring with a commercially available nasopharyngeal pH-monitoring device, Dx-pH Measurement System from Restech, San Diego, Calif. Subjects with reflux were classified based on the position of reflux as either supine only, upright only, or both supine and upright. In a subset of subjects with supine-only reflux, pH monitoring was compared before and after elevating the head of bed 6 inches. Adequate nasopharyngeal pH-monitoring data were obtained for 235 patients. Reflux was detected in 113 (48%) patients. The pattern of reflux observed was 62 (55%) supine only, 4 (4%) upright only, and 47 (42%) upright and supine. Sequential overnight nasopharyngeal pH monitoring before and after head-of-bed elevation was obtained in 13 individuals with supine-only reflux. Ten subjects demonstrated significant improvement, 8 of whom demonstrated complete resolution of supine reflux with 6 inches of head-of-bed elevation. This study provides new evidence that SERD frequently occurs in the supine position and that 6 inches of head-of-bed elevation is effective in reducing supine SERD.

    Gastroesophageal reflux disease (GERD) and psychological stress are associated with sleep disturbances. The aim of the present study was to examine the prevalence of sleep disturbances, anxiety, and depression by GERD subtypes and to identify factors associated with sleep disturbances in general population. A total of 2002 Japanese subjects, who underwent annual health checkups, were enrolled and asked to fill out a questionnaire, including the frequency scale for the symptoms of GERD (FSSG), Athens Insomnia Scale (AIS), Rome III questionnaire, and Hospital Anxiety and Depression Scale (HADS). GERD was divided into asymptomatic erosive reflux disease (a-ERD), symptomatic ERD (s-ERD), and non-erosive reflux disease (NERD), according to the presence or absence of esophageal mucosal injury on endoscopy, and the FSSG scores. Sleep disturbances were diagnosed in subjects with AIS score ≥6. Prevalence of sleep disturbances was significantly higher in GERD subjects than in controls (35.9 and 14.7%, respectively), especially, in the NERD group (45.1%). Sleep duration was significantly shorter in the s-ERD group compared with other groups. Subjects in the NERD and s-ERD groups showed higher HADS scores, resulting in higher incidences of anxiety and depression than those in the control and a-ERD groups. Reflux symptoms, anxiety, depression, and coexisting functional dyspepsia, but not the presence of esophageal mucosal injury, were associated with an increased odds ratio for sleep disturbances. There were significant positive associations among reflux symptoms, psychological stress, and sleep disturbance in Japanese adults. Further studies investigating the efficacy of therapy are needed.

    Gastro-esophageal reflux disease (GERD) is one of the most common disorders in gastroenterology. Patients present with or without increased acid exposure indicating a non-uniform 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 sub-chronic 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 cellline 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 pro-inflammatory cytokines. Proteomic and transcriptomic analyses identified CINC1-3, MIP-1/3α, MIG, RANTES and 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 up-regulated 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 up-regulated 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.

    Gastric emptying has an important role in the pathophysiology of gastroesophageal reflux disease. The effect of metoclopramide, a gastric prokinetic agent, in gastroesophageal reflux patients with normal as well as delayed emptying was investigated. Twenty-six patients with subjective and objective evidence of gastroesophageal reflux ingested an egg salad sandwich meal labeled with /sub 99m/technetium-DTPA for a baseline study, and then again on a separate day after receiving oral metoclopramide, 10 mg, 30 min prior to the test meal. The mean percent isotope remaining in the stomach after 90 min improved significantly from 70.3 +/- 3.9% (SEM) to 55.2 +/- 4.2% after metoclopramide. Fourteen (54%) had a basal emptying in the normal range of 34-69% retention of isotope at 90 min, (means +/- 2 SD), while it was slow in 12 (46%). For those with delayed basal gastric emptying, the mean retention of 88.9 +/- 2.9% at 90 min was significantly decreased by metoclopramide to 68.6 +/- 6.1%. In those patients with a normal basal gastric emptying and a mean retention of 54.4 +/- 2.3% at 90 min, there was also significant improvement (P less than 0.025) to 43.6 +/- 3.6% after metoclopramide. These data indicate that metoclopramide increased gastric emptying in gastroesophageal reflux patients with normal as well as delayed gastric emptying. Therefore on a patient management level a trial of metoclopramide is warranted in patients with gastroesophageal reflux disease and is not limited by the gastric emptying status of the patient.

    The prokinetic agent cisapride is effective for the treatment of gastroesophageal reflux disease (GERD) in infants and children, but is no longer used for this purpose because of safety concerns. Therefore, other pharmacological agents need to be investigated for efficacy in GERD treatment. In this study, we examined the effectiveness and safety of mosapride for the treatment of neurologically impaired children and adolescents with GERD. Mosapride (0.3 mg/kg/day) was administered to 11 neurologically impaired patients with GERD (five male; median age, 12.3 years). Esophageal acid exposure was measured using esophageal pH monitoring before and at >5 days after the start of mosapride treatment. The pressure and length of the lower esophageal sphincter were compared before and after mosapride treatment. In the 11 patients, median reflux index (percentage of the total monitoring period during which recorded pH was reflux (range, 0.5-2.1 min/reflux) before and 0.7 min/reflux (range, 0.4-1.2 min/reflux) after treatment with mosapride (P = 0.02). The median number of reflux episodes before (219) and after (122) drug treatment did not differ significantly. The decreased reflux index in neurologically impaired patients with GERD is due to mosapride, therefore mosapride may be a candidate for GERD treatment. © 2016 Japan Pediatric Society.

    Pediatric gastroesophageal reflux disease (GERD) is a disorder difficult to diagnose and to treat. Due to the current definition of GERD, i.e. gastroesophageal reflux (GER) causing bothersome symptoms and/or complications, diagnosis is subject to broad interpretation.

    Helicobacter pylori is associated with gastritis, peptic ulcers and gastric malignancies. Little attention has been paid to the possibility that it may also have a role in the pathogenesis of reflux oesophagitis. This is especially true in elderly patients who have life-long infection and provide an ideal group to study the mucosal changes associated with the organism. The aim of this study was to determine if H pylori is associated with reflux oesophagitis in elderly patients. Consecutive gastroscopy patients were recruited. Multiple biopsies were taken from oesophagus, stomach, antrum and duodenum for histology and rapid urease tests. Patients also had IgG ELISA antibodies and 13C-urea breath tests performed. Patients with macroscopic or microscopic evidence of reflux oesophagitis were compared to patients with macroscopically normal upper gastrointestinal tracts and no microscopic evidence of reflux. A total of 114 patients were recruited, average age 78.9 years (+/- 5.4). There were 37 refluxers and 33 non-refluxers. We found no evidence for an association between the presence of H pylori and reflux oesophagitis in elderly patients. The high prevalence of H pylori in patients with reflux oesophagitis can be explained by the presence of incidental gastritis. PMID:8733530

    To determine whether a pH probe or multichannel intraluminal impedance (MII) more frequently detected gastro-oesophageal reflux and test the hypothesis that acid reflux was associated with lower baseline impedance. A prospective study of infants in whom reflux was suspected and evaluated using combined pH and multichannel impedance. Studies were considered abnormal if the acid index was >10% or there were >79MII reflux events in 24 hours. The acid index was the percentage of total study time with a pHacid clearance time (ACT) the time from the pH falling below four to rising above four. Forty-two infants [median gestational age 31 (range 23-42) weeks] were assessed. Only nine infants (21%) had abnormal studies, seven detected by pH monitoring, one by MII monitoring and one by both techniques (p = 0.04). After correcting for gestational age and post-natal age, baseline impedance remained negatively correlated with the acid index (r = -0.34, p = 0.038) and the maximum ACT (r = -0.44, p = 0.006). Clinical suspicion of reflux was frequently incorrect, and reflux was more frequently detected by a pH probe. The inverse relationship of acid reflux to baseline impedance suggests that mucosal disruption may result from acid reflux in this population. ©2018 Foundation Acta Paediatrica.

    Asthma and recurrent bronchopneumopathies in children are often associated with gastroesophageal reflux. Cine-esogastroscintigraphy is proposed for demonstrating reflux and establishing its direct or indirect responsibility in respiratory disease. 133 patients aged 5 months to 16 years were studied. Reflux was found in 65.5% of cases, either severe (44.4% of cases) or minor (21.1%). Episodes of reflux produced respiratory manifestations in 7% of patients. Inhalation of refluxed material was proved in 3% by demonstration of pulmonary contamination. Sensitivity of cine-esophagogastroscintigraphy is comparable to that of esophageal pH measurement for detection of reflux. It does not require positioning of a probe in the esophageal lumen. It provides quantitative parameters on esophageal transit, reflux and gastric voiding, and demonstrates pulmonary contamination. It is easy to perform and can be readily included in an outpatient clinic workup. Its sensitivity and reliability make it a useful tool for evaluation of therapeutic efficiency. The interlocking of various physiopathologic factors contributes to the polymorphism of respiratory manifestations of reflux.

    Single anastomosis gastric bypass (SaGB) was introduced in 2001 as an alternative to "loop" gastric bypass. It was considered as a procedure that would eliminate alkaline reflux and associated esophagitis. Existing evidence about the postoperative incidence of gastroesophageal reflux (GERD) after SaGB is based on studies using symptom questionnaires. The aim of our study was to evaluate GERD 12 months after SaGB by using 24-hour multichannel intraluminal impedance pH metry (24-h MIIpH). Surgical department of a university hospital METHODS: Morbidly obese candidates for SaGB underwent 24-hour MIIpH prior and 12 months after their bariatric procedure. There were 11 patients included in this prospective study. Results of 24-hour MIIpH revealed that DeMeester score (40.48 versus 24.16, P = .339) had an increasing trend 12 months after SaGB. Acid reflux episodes decreased, whereas nonacid reflux episodes increased postoperatively, both in proximal and distal esophagus. Total median bolus clearance time and acid clearance time increased. De novo GERD developed in 2 patients (28.6%) and worsening of already existing GERD developed in all patients with preoperative evidence of GERD. The use of symptom questionnaires to assess postoperative GERD after SaGB may not accurately depict the real image. Twenty-four-hour MIIpH in 12 months after SaGB revealed an increase of total number of nonacid reflux episodes and a decrease of total number of acid reflux episodes, with longer duration of each acid reflux episode. Close postoperative follow-up with reflux testing and possibly endoscopy could eliminate the risk of complicated GERD. Copyright © 2017 American Society for Bariatric Surgery.

    The therapeutical approach to vesicoureteral reflux (VUR) depends on assessment of the renal involvement. The effective renal plasma flow (ERPF) and parenchymal mean transit time of radiotracer (pMTT) of the affected kidney are sensitive functional parameters. We investigated the association of these functional indices with the volume of refluxed urine. In 64 children (mean age 6.4 yrs) the presence of VUR was confirmed with direct radionuclide cystography in 80 ureters (48 unilateral and 32 bilateral) and the maximal volume of refluxed urine (MVRU) was determined for each uretero-renal unit. All patients also underwent dynamic renal scintigraphy with I-131-hippuran, providing the values of pMTT and relative renal hippuran clearances of the respective kidneys by deconvolution analysis. In 37 of the affected kidneys ERPF was also determined by combining the latter results with total ERPF, determined by plasma clearance of hippuran. Using the borderline value of MVRU of 4 ml, the group with higher MVRU exhibited significantly lower ERPF of the affected kidney (194±93 vs. 270±77 ml/min/1.73 m2, p=.002) and significantly higher proportion of pMTT's over 3.5 min (31/33 vs. 17/47, p=.003). The negative linear correlation between MVRU and ERPF was found (r=-.45, p=.006). We conclude that quantitative radionuclide cystography, aside from diagnosis and follow-up of VUR, may also provide insight in the function of the affected kidney and thus contribute in designing the therapeutical approach.

  16. Role of endoscopy in gastroesophageal reflux disease

    Full Text Available Gastroesophageal reflux disease is a condition due to reflux of stomach content in the esophagus causing trouble symptoms or complications or both. GERD is a clinical diagnosis and typically presents with a heartburn and/or regurgitation and a positive response to antacid secretory medications. GERD is the leading outpatient diagnosis among all gastrointestinal disorders in the United States. Approximately 40% of population report occasional symptoms of GERD whereas 10-20% of patients will have symptoms at least once in a week. Recent guidelines from gastrointestinal societies such as American College of Gastroenterology, American Society for Gastrointestinal Endoscopy and American College of Physicians have laid out specific indications regarding role of esophagogastroduodenoscopy in GERD. Despite these recommendations, studies have revealed that one-fifth to two-fifth EGDs may not be clinically indicated, especially where open access endoscopy referral system is used. Traditionally, GERD has been thought to be a disease of the western world. Prevalence rates had been estimated to be lower in Asia when compared to that of the Western Countries. Few recent epidemiological studies in India showed the prevalence of reflux disease in India to be between 8-24%, which is comparable to the western world. The use of EGDs becomes more critical for developing countries such as India where prevalence of GERD and BE is comparable to the western countries but have limited resources. In addition to direct cost for an EGD, it burdens economy with indirect costs such as time off from the work, transportation and any procedural complications. Risk stratifying patients with GERD may therefore prevent unnecessary procedures, harms and costs. The aim of this paper is to review the existing evidence on the role of endoscopy in GERD.

    Bile reflux may occur after a variety of reconstructive procedures in the gastro-intestinal tract and biliary system. The present paper deals with reflux into the duodenum, jejunum, stomach, oesophagus and into blind loops. The demonstration of reflux by sup(99m)Tc labelled IDA acid derivatives, and a possible quantitative approach, are discussed. The advantages of isotope methods are: 1. Direct demonstration of bile reflux without any intervention in the physiological process and with little trouble to the patient. 2. The ability to use the method for various reconstructive procedures and 3. the additional information obtained which may help in the differential diagnosis of blind loops, biliary obstruction, cholecystitis or liver metastases if there has been a gastrectomy for a malignant tumour. In combination with a second administration of a radio-isotope tracer, one may be able to demonstrate abnormalities in the motility of the stomach or gut, or pyloric stenosis or gastro-oesophageal reflux.

    Gastro-oesophageal reflux disease (GORD) develops when reflux of gastric content causes troublesome symptoms or complications. The main symptoms are heartburn and acid regurgitation and complications include oesophagitis, strictures, Barrett's oesophagus and oesophageal adenocarcinoma. In addition to hereditary influence, GORD is associated with lifestyle factors, mainly obesity. Tobacco smoking is regarded as an aetiological factor of GORD, while alcohol consumption is considered a triggering factor of reflux episodes and not a causal factor. Yet, both tobacco smoking and alcohol consumption can reduce the lower oesophageal sphincter pressure, facilitating reflux. In addition, tobacco smoking reduces the production of saliva rich in bicarbonate, which is important for buffering and clearance of acid in the oesophagus. Alcohol also has a direct noxious effect on the oesophageal mucosa, which predisposes to acidic injury. Tobacco smoking cessation reduces the risk of GORD symptoms and avoidance of alcohol is encouraged in individuals where alcohol consumption triggers reflux. Copyright © 2017 Elsevier Ltd.

  19. Proton Pump Inhibitors in Gastroesophageal Reflux Disease: Friend or Foe.

    2017-09-01

    Proton pump inhibitor (PPI) use in gastroesophageal reflux disease (GERD) has been redefined, in light of recent advances highlighting GERD phenotypes that respond to PPIs, and fresh revelations of potential risks of long-term PPI therapy. Erosive esophagitis predicts excellent response to PPI therapy, but non-erosive reflux disease (NERD) with abnormal reflux parameters on ambulatory reflux monitoring also demonstrates a similar response. In contrast, response is suboptimal in the absence of abnormal reflux parameters. In this setting, if an alternate appropriate indication for PPI therapy does not coexist, risks may outweigh benefits of PPI therapy. Adverse events from long-term PPI therapy continue to be reported, most based on association rather than cause-and-effect. Appropriate indications need to be established before embarking on long-term PPI therapy. Future research will define true risks of long-term PPI therapy, and develop alternate management options for acid peptic diseases.

    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%

    To study the correlation of obstructive sleep apnoea (OSA) and laryngopharyngeal reflux (LPR). A descriptive study. Suez Canal University Hospital, Ismailia, Egypt. 62 patients with polysomnography confirmed OSA. Patients were evaluated with ambulatory 24-h double channel pH monitoring. Mean reflux symptom index in the study group was 9 ± 5.5, and it was > 13 in all patients with severe OSA. Signs of LPR reflux were present in 34 (55%) patients. Abnormal reflux was detected in the distal oesophagus in 41 patients (66%) and in the proximal oesophagus in 21 patients (34%). Patients with severe OSA had significantly higher nocturnal LPR reflux episodes compared to patients with mild disease (P .05). LPR is common in patients with OSA. Patients with severe OSA have significantly higher nocturnal LPR. This should be considered when treating this group of patients. © 2016 John Wiley & Sons Ltd.

    Widespread epidemiological changes, rising prevalence and gradual shifts in patterns of disease manifestations: this is the changing face of gastroesophageal reflux disease (GERD) in Asia. Are we witnessing a disease in evolution or merely the result of increased and more accurate case reporting that comes with advancing diagnostic technology, better medical facilities and heightened awareness of the disease? Do the figures reported really reflect the actual scenario or is there more to it than meets the eye? In this article, we take you back in time to review relevant developments over the past decade or so. We will draw on findings from across Asia, take an in-depth look at prevailing trends and patterns and examine some of the most plausible explanations behind the dynamics of this epidemiological transition.

    The most common extraesophageal manifestations of gastroesophageal reflux disease (GERD) include chronic cough, asthma and laryngitis. There are two mechanisms proposed to explain extraesophageal syndromes caused by GERD. The first one is a direct way via irritation and/or microaspiration and the second one is an indirect, vagally mediated way. The investigation of extraesophageal manifestations of GERD is difficult and the empirical therapy with proton pump inhibitors usually double dose for at least three months is still the most common approach.

    This prospective multicenter investigation was conducted to define the repeatability of duplex-based identification of venous reflux and the relative effect of key parameters on the reproducibility of the test. Repeatability was studied by having the same technologist perform duplicate tests, at the same time of the day, using the same reflux-provoking maneuver and with the patient in the same position. Reproducibility was examined by having two different technologists perform the test at the same time of the day, using the same reflux-provoking maneuver and with the patient in the same position. Facilitated reproducibility was studied by having two different technologists examine the same patients immediately after an educational intervention. Limits of agreement between two duplex scans were studied by changing three elements of the test: time of the day (morning vs afternoon), patient's position (standing vs supine), and reflux initiation (manual vs automatic compression-decompression). The study enrolled 17 healthy volunteers and 57 patients with primary chronic venous disease. Repeatability of reflux time measurements in deep veins did not significantly differ with the time of day, the patient's position, or the reflux-provoking maneuver. Reflux measurements in the superficial veins were more repeatable (P ultrasound detection of venous reflux. Reports should include information on the time of the test, the patient's position, and the provoking maneuver used. Adopting a uniform cut point of 0.5 second for pathologic reflux can significantly improve the reliability of reflux detection. Implementation of a standard protocol should elevate the minimal standard for agreement between repeated tests from the current 70% to at least 80% and with more rigid standardization, to 90%.

    Full Text Available We have studied morphofunctional state of esophageal mucosa in 57 patients with gastroesophageal reflux disease (GERD with normal (body mass index (BMI — 18.5–24.9 kg/m2 and excessive (BMI over 25 kg/m2 body weight. A histologic and morphometric study of esophageal mucosa, immunohistochemical analysis of the expression of apoptosis marker CD95 and inflammatory marker cyclooxygenase-2 (COX-2 were carried out. In reflux esophagitis, most characteristic are changes in multilayered epithelium — hyperkeratosis, parakeratosis, proliferation of basal cells and acanthosis. At that, significant differences in morphometric characteristics of patients with normal BMI and overweight were not found. The development of reflux esophagitis was associated with violations of pro-apoptotic ability of esophageal mucosa cells and increased expression of COX-2, most significant in patients with high BMI. Detected disorders may determine the mechanisms of complicated course of GERD in these patients.

    To study the relationship between esophageal motor functional disorder [decreased lower esophageal sphincter pressure (LESP)and ineffective motility (IEM)] and gastroesophageal reflux disease (GERD). Totally 89 patients with GERD were enrolled in this study. All of them underwent 24-hour pH monitoring with dual-channel probe and stationary esophageal manometry. In addition, 77 of these patients underwent upper endoscopy. IEM and LES, 10 mmHg were common disturbances in patients with GERD (54% and 48%, respectively). The number of the acid reflux events of distal esophagus and prevalence of moderate or severe erosive esophagitis (EE) were significantly higher in patients with low LESP and IEM than patients without low LESP ( Pesophagus was significantly correlated with the severity of esophagitis, distal esophagus amplitude, and LESP, while no such correlation was found between IEM and degree of esophageal acid exposure or esophagitis. The pathophysiology of GERD is probably multifactorial. Lower LESP or IEM is not a independent pathophysiological factor for GERD. However,one single factor is insufficient to explain all the pathogenic mechanism of GERD.

    The development of lipid aspiration pneumonia after chronic nasopharyngeal installation of mineral oil was first described in 1925 by Laughlin. Since that time this entity has been well recognized and numerous substances have been identified or implicated as the aspirated material. The classic radiographic appearance of severe chronic lipid aspiration pneumonia has been described as consisting of intense perihilar infiltrates. However, the radiographic findings are more often non-specific and usually consist of varying degrees of diffuse interstitial infiltrates that tend to be more prominent in the perihilar regions and the right lung. We are reporting a case of biopsy-proven lipid aspiration pneumonia in an infant with known gastro-esophageal reflux (GER) who had medium-chain triglyceride oil administered via nasogastric tube. Serial roentgenograms demonstrated a changing pulmonary pattern from diffuse bilateral interstitial infiltrates initially to a diffuse alveolar pattern at the time of the lung biopsy. Modern medicine has developed new methods for providing nourishment to sick newborns and infants to improve their nutritional status and help them to grow. One such method involves the administration of medium-chain triglycerides (MCT oil) into the GI tract via a nasogastric or nasoenteral tube. The purpose of this report is to describe a significant complication of this method of providing nutrition to an infant with gastroesophageal reflux (GER) and the diagnostic dilemma it presented.

    Renal uptake rate was calculated by 99m Tc-dimercaptosuccinic acid (DMSA) scintigraphy in 100 kidneys from 58 patients with pediatric vesicoureteral reflux (VUR) to assess kidney function quantitatively for treatment selection and surgical timing. The conservatively treated group consisted of 42 patients (75 kidneys) who underwent DMSA renal scintigraphy twice at intervals of 2 years during their management. The surgically treated group consisted of 16 patients (25 kidneys) who underwent DMSA renal scintigraphy before and 2 years after surgery, Urine samples were collected at the time of initial DMSA renal scintigraphy for the simultaneous measurement of β 2 -microglobulin (β 2 -MG), α 1 -microglobulin and N-acetyl-β-glucosaminidase. Renal uptake ratio of DMSA did not differ in VUR grades during a 2-year follow-up period in the conservative group. In the age group of patients aged 2 or less, renal uptake ratio decreased 2 years later, with significant difference with that in the other age groups. According to VUR grade, there was no significant difference in DMSA renal kidney ratios between the conservative group and the surgical group. According to age, significant difference in renal uptake ratio was observed between the two groups; i.e., patients aged 2 or less had a significantly decreased renal uptake ratio in the conservative group than the surgical group. However, the renal uptake ratio did not differ in the other age groups. For patients aged 2 or less, surgery was considerd necessary to prevent reflux when urinary β 2 -MG indexes are increased. For those aged 3 years or more, on the other hand, conservative treatment was considered optimal regardless of VUR grades; surgery was considered recommended in the case of repeated urinary infection and decreased renal function.

    Nasal modes of respiratory support cause variable amounts of gastric dilatation which may increase gastro-oesophageal reflux (GER) in preterms. To compare the incidence of GER in nasally ventilated, preterm babies with controls (babies not on ventilation). A prospective, observational comparative study. Twenty-three preterm babies of gestational age 28-36 weeks and weight ranging between 1,000 g and Reflux index (RI) was calculated as the percentage of study time the lower oesophageal pH was reflux with symptoms if any. Numerical data were shown as mean with standard deviation and statistical comparisons were done using the χ(2)-test, Fischer test, and t-test wherever applicable. The RI was higher in ventilated babies as compared to the control group, particularly in the subgroup A, where test babies formed their own controls. Grade IV reflux (7 cases) was seen only in the ventilated babies. There was no difference in the incidence of GER in babies on nCPAP as compared with nIPPV. Grade IV reflux could not be reliably predicted by RI alone. No definite temporal relation between episodes of reflux and symptoms could be determined in this study. There is an increase in GER in preterms on nasal modes of ventilation. A combination of upper (pharyngeal) and lower oesophageal sensors are preferred to a single lower oesophageal sensor when assessing GER by oesophageal pHmetry in neonates.

    The confluence between the increased prevalence of gastro-esophageal reflux disease (GERD) and of obesity has generated great interest in the association between these two conditions. Several studies have addressed the potential relationship between GERD and obesity, but the exact mechanism by which obesity causes reflux disease still remains to be clearly defined. A commonly suggested pathogenetic pathway is the increased abdominal pressure which relaxes the lower esophageal sphincter, thus exposing the esophageal mucosal to gastric content. Apart from the mechanical pressure, visceral fat is metabolically active and it has been strongly associated with serum levels of adipo-cytokines including interleukin-6 and tumor necrosis factor α, which may play a role in GERD or consequent carcinogenesis. This summary is aimed to explore the potential mechanisms responsible for the association between GERD and obesity, and to better understand the possible role of weight loss as a therapeutic approach for GERD.

  14. How useful is gastroesophageal reflux scintigraphy in suspected childhood aspiration

    It has been suggested that gastroesophageal reflux scintigraphy might be useful in assisting one in determining therapy for patients suspected of aspirating or becoming apneic secondary to gastroesophageal reflux. This, however, has not been our experience and in reviewing 23 patients with recurrent pneumonia and/or apnea who had gastroesophageal reflux scintigraphy, we were able to detect aspiration in only one. This was especially significant since 13 (59%) of these patients had demonstrable reflux, and of these, eight were treated successfully for suspected aspiration even though none was demonstrated isotopically. To be sure, the demonstration of pulmonary aspiration with gastroesophageal reflux scintigraphy had little influence on patient selection and response to therapy. For this reason we feel there is little justification in depending on the GRS for the specific purpose of trying to document pulmonary aspiration in infants and children who are refluxing. One of the more serious complications of gastroesophageal (GE) reflux is aspiration leading to recurrent pulmonary infections and/or apnea. However, it always has been difficult to demonstrate actual aspiration into the lungs, and to be sure, barium studies of the upper GI tract seldom reveal this complication. Recently, however, considerable interest has been generated in gastroesophageal scintigraphy (GRS) as a possible means of documenting such aspiration. Rationale for this stems from the fact that suspected patients can be studied over a longer period of time and in addition, delayed and overnight images can be obtained. However, our experience does not support GRS as being an adequate method for demonstrating aspiration.

    Background Refractory gastroesophageal reflux-induced chronic cough (GERC) is difficult to manage. The purpose of the study is to evaluate the efficacy of a novel stepwise protocol for treating this condition. Methods A total of 103 consecutive patients with suspected refractory reflux-induced chronic cough failing to a standard anti-reflux therapy were treated with a stepwise therapy. Treatment commences with high-dose omeprazole and, if necessary, is escalated to subsequent sequential treatment with ranitidine and finally baclofen. The primary end-point was overall cough resolution, and the secondary end-point was cough resolution after each treatment step. Results High-dose omeprazole eliminated or improved cough in 28.1% of patients (n=29). Further stepwise of treatment with the addition of ranitide yielded a favorable response in an additional 12.6% (n=13) of patients, and subsequent escalation to baclofen provoked response in another 36.9% (n=38) of patients. Overall, this stepwise protocol was successful in 77.6% (n=80) of patients. The diurnal cough symptom score fell from 3 [1] to 1 [0] (Z=6.316, P=0.000), and the nocturnal cough symptom score decreased from 1 [1] to 0 [1] (Z=–4.511, P=0.000), with a corresponding reduction in the Gastroesophageal Reflux Diagnostic Questionnaire score from 8.6±1.7 to 6.8±0.7 (t=3.612, P=0.000). Conversely, the cough threshold C2 to capsaicin was increased from 0.49 (0.49) µmol/L to 1.95 (2.92) µmol/L (Z=–5.892, P=0.000), and the cough threshold C5 was increased from 1.95 (2.92) µmol/L to 7.8 (5.85) µmol/L (Z=–5.171, P=0.000). Conclusions Sequential stepwise anti-reflux therapy is a useful therapeutic strategy for refractory reflux-induced chronic cough. PMID:26904227

    Mucosal integrity can be assessed in patients with gastroesophageal reflux disease (GERD) by measuring intraluminal baseline impedance (BI). However, it is not clear whether BI is abnormal in patients with functional heartburn (FH), or can be used to distinguish them from patients with GERD. We compared differences in BI between patients with FH vs GERD. We performed a prospective study of 52 patients (16 men; mean age, 55 y; range, 23-78 y) seen at a tertiary university hospital from February 2009 through December 2012. Thirty-five patients had GERD (19 had nonerosive reflux disease [NERD], 16 had erosive reflux disease [ERD]) and 17 had FH. All patients discontinued proton pump inhibitor therapy and then underwent esophagogastroduodenoscopy and multichannel intraluminal impedance and pH monitoring. BI was assessed at 3, 5, 7, 9, 15, and 17 cm proximal to the lower esophageal sphincter in recumbent patients. Biopsy specimens were taken from 3 cm above the gastroesophageal junction; histology analysis was performed to identify and semiquantitatively score (scale, 0-3) dilated intercellular spaces. Baseline impedance in the distal esophagus was significantly lower in patients with NERD or erosive reflux disease (ERD) than FH (P = .0006). At a cut-off value of less than 2100 Ω, BI measurements identified patients with GERD with 78% sensitivity and 71% specificity, with positive and negative predictive values of 75%. Also in the proximal esophagus, reduced levels of BI levels were found only in patients with ERD. There were negative correlations between level of BI and acid exposure time (r = -0.45; P = .0008), number of acidic reflux episodes (r = -0.45; P = .001), and proximal extent (r = -0.40; P = .004). Biopsy specimens from patients with NERD or ERD had significant increases in dilation of intercellular spaces, compared with those from patients with FH; there was an inverse association between dilated intercellular spaces and BI in the distal esophagus

    We study 22 children with clinical symptoms of gastroesophageal reflux. The main manifestations were: frequent vomiting, failure to thrive and repetitive pneumonia. In all of them we perform barium esophagogram (SEGD) with fluoroscopy, esophageal manometry (EM) and a four hours intraesophageal pH measurement. Thirteen of the twenty two children present a pathologic reflux (ERGE); in 16 we found SEGD that show reflux; three of them had an abnormal EM, the other 13 were normal. Seven patients showed alteration of the intraesophageal pH measurement. In conclusion the intraesophageal pH measurement in short period of time (4 hours) is a good method in the diagnosis of patients with ERGE.

    A case of malacoplakia involving the lower urinary tract of a young black boy, with associated bilateral vesicoureteral reflux, hydronephrosis and selective immunoglobulin A deficiency is reported. Reflux was caused by the malacoplakia. Reflux and hydronephrosis persisted despite elimination of bacterial infection and malacoplakia by drug therapy. These abnormalities were corrected by a conventional antireflux operation. Malacoplakia appears to be related to immunologic incompetence and diminished levels of intracellular cyclic 3',5' guanine monophosphate. Cholinergic agonists reverse or prevent the pathological changes of malacoplakia.

    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.

    neonates treated with domperidone over 24 hours showed that although reflux frequency was significantly increased, reflux duration was significantly improved.Diversity of RCT evidence was found regarding efficacy of compound alginate preparations(Gaviscon Infant(®) ) in infants, although as a result of these studies, Gaviscon Infant(®) was changed to become aluminium-free and has been assessed in its current form in only two studies since 1999. Given the diversity of study designs and the heterogeneity of outcomes, as well as the evolution in formulation, it was not possible to perform a meta-analysis on the efficacy of Gaviscon Infant(®) . Moderate evidence indicates that Gaviscon Infant(®) improves symptoms in infants, including those with functional reflux; the largest study of the current formulation showed improvement in symptom control but was limited by length of follow-up.No serious side effects were reported.No RCTs on pharmacological treatments for children with neurodisability were identified. Moderate evidence was found to support the use of PPIs, along with some evidence to support the use of H₂ antagonists in older children with GORD, based on improvement in symptom scores, pH indices and endoscopic/histological appearances. However, lack of independent placebo-controlled and head-to-head trials makes conclusions as to relative efficacy difficult to determine. Further RCTs are recommended. No robust RCT evidence is available to support the use of domperidone, and further studies on prokinetics are recommended, including assessments of erythromycin.Pharmacological treatment of infants with reflux symptoms is problematic, as many infants have GOR, and little correlation has been noted between reported symptoms and endoscopic and pH findings. Better evidence has been found to support the use of PPIs in infants with GORD, but heterogeneity in outcomes and in study design impairs interpretation of placebo-controlled data regarding efficacy. Some evidence is

    We compared newly developed radionuclide cystography with conventional contrast voiding cystography (VCG) with regard to their diagnostic usefulness of intrarenal reflux (IRR) in children. Based on the imaging findings, we assessed the role of IRR in the pathogenesis of reflux nephropathy (RN). Among the ureters which revealed IRR diagnosed by radionuclide cystography, 38.9% (7 out of 18 ureters) of the cases examined by VCG had IRR. In the case of VCG, the sensitivity and specificity of IRR detection were 33.3% and 100%, respectively. There was a statistical correlation between the presence/absence of IRR and vesicoureteral reflux (VUR). RN was significantly correlated with advanced grade of VUR associated with IRR. Among 9 kidneys of the subjects who had suffered from urinary tract infection (UTI) only once, IRR was detected in 33.3% (3/9) and RN in 66.7% (2/3). From these findings, conventional contrast VCG is considered not effective for the diagnosis of IRR. Moreover, it is suggested that VUR complicated with IRR is deeply associated with the development of RN. In addition, it is suggested that UTI might be related to the onset of IRR. (author)

    Full Text Available We examined 58 patients with erosive form of gastroesophageal reflux disease and 10 healthy volunteers. All patients underwent fibrogastroduodenoscopy, 24 hour pH monitoring in the lower third of esophagus, 13C-octanoate breath test, identified concentration of cholecystokinin-pankreozymin in blood serum. It is found that 44.83 % of patients with gastroesophageal reflux disease have delayed, 36.21 % — rapid and 18.97 % — normal motor-e­vacuation function of the stomach. In patients with delayed gastric motility we observed prevalence of bile reflux with pH over 6 in the lower third of the esophagus, amounting to 42 % (p = 0.044, and increased concentration in the blood of cholecystokinin-pankreozymin up to (7.12 ± 0.21 ng/ml (p < 0.05, in healthy subjects — (5.91 ± 0.34 ng/ml. In patients with accelerated motility number of refluxes under 4 was 45 %, and cholecystokinin-pankreozymin le­vel — (4.4 ± 1.2 ng/ml. These data support the view of other authors that causes of heartburn as a leading symptom of gastroesophageal reflux disease can be duodenogastric reflux and visceral hyperalgesia.

    The evaluation of symptom association between gastroesophageal reflux and cardiorespiratory events in preterm infants remains unclear. This paper describes a conservative approach to decision-making of anti-reflux surgery through symptom association analysis. Forty-three neonates with potentially reflux-related cardiorespiratory symptoms underwent synchronized esophageal impedance-pH and cardiorespiratory monitoring. Three indices were considered to evaluate symptom association, the symptom index (SI), the symptom sensitivity index (SSI) and the symptom association probability (SAP). A conservative strategy was adopted regarding the decision of anti-reflux surgery, and therefore, patients were scheduled for laparoscopic Nissen fundoplication if the three indices showed a positive assessment of symptom association. Retrospectively, these indices and the binomial symptom index (BSI) were contrasted against the decision of anti-reflux surgery using different windows of association. Thirteen patients showed positive symptom association but only two underwent anti-reflux surgery. The SI and the SSI showed an increasing trend with the width of the window of association. The SAP was affected randomly by slightly altering the windowing parameters. The BSI showed the best performance with the two-minute window (κ =0.78) CONCLUSIONS: The pathology under study is known to improve with maturity. However, the severity of cardiorespiratory symptoms may threaten the neonate's life and therefore, in some occasions, invasive treatments must be considered to protect life. The BSI provides a good prediction of a combination of positive SI, SSI and SAP, which may improve clinical decisions. However, further clinical studies are required to prove the BSI as an optimal predictor of clinical outcomes. Copyright © 2015 Asociación Española de Pediatría. Publicado por Elsevier España, S.L.U.

    Since its inception as a technology in the United States, endoscopic correction of vesicoureteral reflux has become a popular treatment option in children with vesicoureteral reflux with reported wide use. We determined whether the increasing trend in use in the United States after the introduction of dextranomer/hyaluronic acid has been sustained. We abstracted data on pediatric patients treated with ureteral reimplantation or dextranomer/hyaluronic acid intervention for vesicoureteral reflux from 2004 to 2011 from the PHIS (Pediatric Health Information System) database. Patients with coding data indicating diagnoses other than primary vesicoureteral reflux and hospitals reporting less than 80% of ambulatory surgery cases by CPT code were excluded from study. We identified 14,430 patients (17,826 procedures), of whom 49% underwent reimplantation and 51% underwent dextranomer/hyaluronic acid injection. Of the patients 83% were female with a median age at surgery of 4.7 years (IQR 2.5-7.2). Linear regression showed a significant downward trend in the average total number of antireflux operations per institution during the study period. This was attributable to a decrease in the average rate of dextranomer/hyaluronic acid interventions because the average reimplantation rate remained stable during this time. At freestanding pediatric hospitals enrolled in the PHIS database there is a trend toward decreasing intervention for primary vesicoureteral reflux, which appears to be due to decreased use of injection therapy. This may reflect a philosophical change in reflux management by injection therapy. Copyright © 2014 American Urological Association Education and Research, Inc. Published by Elsevier Inc.

    The aim of this study was to determine the efficacy of pectin solution, which increases the viscosity of liquid nutrient, for prevention of gastro-esophageal reflux in comparison with half-solid nutrient. The subjects were 10 elderly patients undergoing percutaneous endoscopic gastrostomy feeding. Twenty-four-hour esophageal multichannel intraluminal impedance and pH testing was performed during intake of half-solid nutrient and a combination of pectin solution and liquid nutrient. During 4 h after delivery, there was no significant difference in the total number of gastro-esophageal reflux events between the feeding of the half-solid nutrient and the combination of pectin solution and liquid nutrient (5.7 ± 1.2 vs 5.3 ± 1.0/4 h). Acidic reflux after delivery of the half-solid nutrient was significantly more frequent than that after delivery of the combination of pectin solution and liquid nutrient (80.7% vs 60.4%, p = 0.018). The incidence of gastro-esophageal reflux reaching the upper portion of the esophagus tended to be higher during delivery of the half-solid nutrient than during delivery of the combination of pectin solution and liquid nutrient (47.4% vs 34.0%, p = 0.153). In conclusion, the usage of pectin solution combined with liquid nutrient is effective for preventing acidic gastro-esophageal reflux and gastro-esophageal reflux reaching the upper portion of the esophagus.

    Gastroesophageal reflux disease lowers the quality of life and increases medical costs. Electroacupuncture has been used to ease symptoms and improve gastrointestinal motility in patients with gastroesophageal reflux disease. The main purposes of this study are to evaluate the efficacy and safety of this procedure. This is a protocol for a randomized, patient-blinded, assessor-blinded, sham-controlled trial. Sixty participants with symptoms of gastroesophageal reflux disease, who have previously undergone standard treatment, will be recruited from August 2015 at Kyung Hee University Korean Medicine Hospital. The participants will be allocated to either the electroacupuncture (n = 30) or the sham electroacupuncture group (n = 30); the allocation will be concealed from both the participants and the assessors. The EA group will undergo penetrating acupuncture at 18 fixed points and two optional points chosen using the pattern identification for gastroesophageal reflux disease. Electrical stimulation will be applied at some of the acupoints. The sham electroacupuncture group will undergo nonpenetrating acupuncture without electrical stimulation at 18 nonspecific points, each of which will be only 2 cm away from the true acupoints used in the electroacupuncture group. In both groups, the procedure will be performed using the Park device. The treatment will last for 6 weeks (with two sessions each week), and the outcome will be evaluated at baseline, 3 weeks, and 6 weeks. The primary outcome will be the proportion of responders with adequate symptom relief, whereas the secondary outcomes will comprise the results of the Nepean dyspepsia index; the Korean gastrointestinal symptom rating scale; the EQ-5D™; levels of gastrin, motilin, and inflammatory cytokines; the perceived stress scale; the qi-stagnation questionnaire; the patient global impression of change; and the spleen qi deficiency questionnaire. The results of this trial will provide information

    To study the clinical curative effect, safety and mechanism of action of electroacupuncture combined with Zhizhukuanzhong capsules (ZZKZC) in treating gastroesophageal reflux disease (GERD). A total of 480 patients with confirmed GERD were randomly divided into four groups: the electroacupuncture group, the ZZKZC group, the combined therapy group, and the control group, with 120 cases in each group. Each case in the electroacupuncture group was treated with electroacupuncture on Zusanli (ST 36), Zhongwan (CV 12), Neiguan (PC 6),Taichong (LR 3) and Gongsun (SP 4) once daily for 6 weeks. Each case in the ZZKZC group was treated with oral administration of 1.29 g ZZKZC three times daily. The combined therapy group had electroacupuncture and ZZKZC. The control group was given oral administration of 5 mg mosapride three times and 20 mg pantoprazole twice daily. The 24-hour intraesophageal total number of reflux episodes with pH or = 0.14), the number of long-term (> or = 5 min) reflux episodes, the percentage of upright time, the percentage of supine time, the percentage of total time of pH or = 0.14), endoscopic grading score, symptom score, quality of life score, and adverse reactions were observed before treatment, at the end of treatment and 54 weeks after treatment in the four groups. The 24-hour intraesophageal pH and bile reflux, endoscopic grading score and symptom score were all significantly decreased at the end of treatment in every group, while the scores of 8 dimensions of quality of life were all increased compared with those before treatment (Pelectroacupuncture group 54 weeks after treatment compared with the end of treatment (P>0.05); however, these indices all significantly deteriorated in the ZZKZC and control groups (P>0.05).

    Purpose: To study the long-term development of urographic renal morphology in adults with vesicoureteral reflux, to investigate the relationship between renal damage and reflux grade, and to analyse the association between the long-term urographic outcome and the occurrence of acute pyelonephritis and reflux during follow-up. The purpose was also to try to distinguish between acquired and developmental renal damage, based on analyses of renal histological specimens and urographic features, and to analyse associated congenital urogenital abnormalities and family history of reflux, reflux nephropathy, urological malformation or death from end-stage renal disease. Material and Methods: Renal damage was identified in 100 (83 women) of 115 adults, selected because of documented reflux. Eighty-seven patients had two urographies done (median interval 14.3 years). The extent and progression of renal damage were assessed and features of developmental renal damage were determined. Histological renal specimens were available in 23 patients with renal damage. Results and Conclusions: The extent of renal damage correlated positively with the severity of reflux. No renal damage developed during the follow-up in 45 previously undamaged kidneys and progression of renal damage was rare (4 of 120 previously damaged kidneys), despite persisting reflux in half of the cases and episodes of acute pyelonephritis during follow-up. Thus, repeated renal imaging is rarely justified in adults with reflux nephropathy. Histological examination showed 'chronic pyelonephritis' in all 23 cases and co-existing renal dysplasia in 1 case. The detailed urographic analysis did not reveal support for developmental renal damage. High frequencies of associated congenital urogenital abnormalities and of a positive family history were found. Thus, congenital and/or hereditary factors cannot be discarded as background factors for the development of renal damage

    Differences in the aetiology as well as patient background of chronic cough have been recognised among US, UK, and Japan. One of the marked differences has been the prevalence of gastro-oesophageal reflux disease (GORD), which has been one of the top three causes in Western countries. It was indeed uncommon or rare in Japan, but, with the increasing prevalence of GOR itself, chronic cough associated with GORD seems to have become more common. In this article, cough associated with GORD will be reviewed based on literature and our Japanese experience. Further, potentially broader relevance of GORD in chronic cough will also be mentioned, highlighting the potential importance of dysmotiliy/non-acid reflux. Copyright © 2017 Elsevier Ltd.

    The patients treated for oesophageal atresia present a correlation between the clinical sintomatology after recanalization characterized by disfagia, dispnea, recurrent cough, chronic pneumopaties and oesophageal anomalies. Where morphological alterations accounting for the presence of gastro-oesophageal reflux (GOR) were not evident, possible functional alterations of the motility were considered. The incidence of GOR was considerably high and, expression of a congenital alteration of the lower oesophageal sphincter and of oesophageal peristalsis, becomes even more severe due to further stretching of the gastro-esophageal junction. The authors underline that the early demonstration of histological changes, even before recanalization, and the motility disorders of the oesophagus have to be well studied, while the LES is normalized, in order to prevent and treat the possible appearance of the well-known complications of GOR.

    A wide variety of symptoms and diseases of the upper aerodigestive tract are associated to gastro-oesophageal reflux disease (GORD). These disorders comprise a large variety of conditions such as asthma, chronic otitis media and sinusitis, chronic cough, and laryngeal disorders including paroxysmal laryngospasm. Laryngo-pharyngeal reflux disease is an extraoesophageal variant of GORD that can affect the larynx and pharynx. Despite numerous research efforts, the diagnosis of laryngopharyngeal reflux often remains elusive, unproven and controversial, and its treatment is then still empiric. Aim of this paper is to review the current literature on upper aerodigestive tract disorders in relation to pathologic gastro-oesophageal reflux, focusing in particular on the pathophysiology base and results of the surgical treatment of GORD.

    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.

    Full Text Available Abstract Background Gastroesophageal reflux disease imposes a significant burden of illness in Western populations. However, data on the impact of reflux symptoms on daily life in Asian populations are scarce. The current study aimed to evaluate the impact of GERD (defined on the basis of symptoms on health-related quality-of-life (HRQoL in individuals from five regions in China, as part of the Systematic Investigation of Gastrointestinal Diseases in China (SILC study. Methods In total, 18 000 residents were randomly selected from across five regions of China and asked to complete a general information questionnaire and a Chinese version of the Reflux Disease Questionnaire (RDQ. A randomly selected subsample of one-fifth of subjects (20% from each region completed Chinese versions of the 36-item self-administered (SF-36 questionnaire and Epworth Sleepiness Scale (ESS questionnaire. Reflux symptoms were defined as the presence of heartburn and/or regurgitation. Symptom-defined GERD was diagnosed as mild heartburn and/or regurgitation ≥2 days per week, or moderate/severe heartburn and/or regurgitation ≥1 day a week, based on the Montreal Definition of GERD for population-based studies. Results The response rate was 89.4% for the total sample (16 091/18 000, and for the 20% subsample (3219/3600. Meaningful impairment was observed in all 8 SF-36 dimensions in participants with symptom-defined GERD, in 7 of the 8 SF-36 dimensions in participants with troublesome reflux symptoms, and in 6 of the 8 SF-36 dimensions in participants with reflux symptoms below the threshold for symptom-defined GERD. Meaningful daytime sleepiness was also observed in each of these groups. The proportion of individuals reporting troublesome symptoms increased as reflux symptom frequency and severity approached the threshold for symptom-defined GERD, and this was associated with concomitant decreases in all HRQoL measures. Troublesome symptoms were reported by 68.2% (75

    Full Text Available Gastroesophageal reflux is overrepresented in people with obstructive sleep apnea (OSA and it has been suggested that OSA worsens gastroesophageal reflux symptoms. Aggravated reflux might lead to an increased risk of Barrett's esophagus.To assess the association between sleep apnea symptoms and Barrett's esophagus.Included in a case-control study in Brisbane, Australia were 237 patients with histologically confirmed Barrett's esophagus and 247 population controls. The controls were randomly selected from the electoral roll and frequency-matched to the cases by age and sex. Information on OSA symptoms (excessive daytime sleepiness and sleep related apnea symptoms, gastroesophageal reflux symptoms and anthropometric measures were collected through interviews and written questionnaires. Multivariable logistic regression provided odds ratios (OR and 95% confidence intervals (CI, adjusted for potential confounding by BMI and gastroesophageal reflux.The prevalence of Barrett's esophagus was higher among people with excessive daytime sleepiness than those without (24% vs. 18%; p-value 0.1142 and in participants with sleep-related apnea symptoms (20% vs. 13%; p-value 0.1730. However, there were non-significantly increased ORs of Barrett's esophagus among people with excessive daytime sleepiness (OR 1.42, 95% CI 0.90-2.34 and sleep related apnea symptoms (OR 1.32, 95% CI 0.74-2.36 when adjusting for age, sex and BMI. After further adjustment for gastroesophageal reflux symptoms, the point ORs were no longer increased (OR 1.02, 95% CI 0.61-1.70 for daytime sleepiness and OR 0.72, 95% CI 0.38-1.38 for sleep related apnea symptoms.Symptoms of OSA are possibly associated with an increased risk of Barrett's esophagus, an association that appears to be mediated entirely by gastroesophageal 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.

  5. Pyelonephritis, renal scarring, and reflux nephropathy: a pediatric urologist's perspective

    2008-01-01

    Imaging of children with a clinical diagnosis of pyelonephritis is performed to characterize the extent of the infection, to identify associated renal injury and to uncover risk factors for future infections and renal damage. Although there is general agreement regarding the need for parenchymal imaging and the need to exclude processes that are either functionally or anatomically obstructive, there is controversy regarding the need for routine cystography, especially when parenchymal involvement has not been documented. A protocol that limits the use of cystography for evaluation of urinary tract infections must assume that the diagnosis of reflux is at least of variable clinical significance. It is now clear that vesicoureteral reflux and reflux nephropathy represent a diverse population that includes both congenital and acquired processes. MR imaging will improve our understanding of vesicoureteral reflux, pyelonephritis and renal scarring and might help us to identify and manage those patients most at risk for recurrent infections and renal injury. To recognize the potential contributions of this newer imaging technique it is helpful to look at our understanding of the pathophysiology of pyelonephritis, reflux and reflux nephropathy. (orig.)

    Gastro-oesophageal reflux is common and benign in children, especially during infancy. Distinguishing between gastrooesophageal reflux, gastro-oesophageal reflux disease and other illnesses presenting as chronic vomiting can be difficult. The general practitioner has a key role to play in identifying if a child requires referral for further investigation. This article outlines the main differential diagnoses to be considered in children presenting with chronic vomiting and/ or regurgitation. We also discuss key management decisions regarding gastro-oesophageal reflux disease in children and when to refer to a specialist for further investigation. Chronic vomiting and regurgitation frequently occurs in infancy and is most commonly due to simple, benign gastrooesophageal reflux, which is usually self limiting without requirement for further investigation. In contrast, gastrooesophageal reflux disease requires considered management and may be a presenting symptom of food allergy requiring more intensive therapy than simple acid suppression. Regular review by the general practitioner to ascertain warning signs will ensure that other serious illnesses are not overlooked and that appropriate investigation and specialist referral are made.

    Summary Background Reflux esophagitis is caused mainly by excessive exposure of the mucosa to gastric contents. In the present study, we examined the effect of several amino acids on acid reflux esophagitis in rats. Material/Methods After 18 h of fasting, acid reflux esophagitis was induced by ligating both the pylorus and the transitional region between the forestomach and the corpus under ether anesthesia, and the animals were killed 4 h later. The severity of esophagitis was reduced by the oral administration of omeprazole, a proton pump inhibitor, or pepstatin, a specific pepsin inhibitor. Results The development of esophageal lesions was dose-dependently prevented by L-arginine and glycine, given intragastrically (i.g.) after the ligation, with complete inhibition obtained at 250 mg/kg and 750 mg/kg, respectively, and these effects were not influenced by the prior s.c. administration of indomethacin or L-NAME. By contrast, both L-alanine and L-glutamine given i.g. after the ligation aggravated these lesions in a dose-dependent manner. These amino acids had no effect on acid secretion but increased the pH of the gastric contents to 1.8~2.3 due to their buffering action. Conclusions The results confirmed an essential role for acid and pepsin in the pathogenesis of acid reflux esophagitis in the rat model and further suggested that various amino acids affect the severity of esophagitis in different ways, due to yet unidentified mechanisms; L-alanine and L-glutamine exert a deleterious effect on the esophagitis, while L-arginine and glycine are highly protective, independent of endogenous prostaglandins and nitric oxide.

    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. © 2014 International Society for Diseases of the Esophagus.

    Gastroesophageal reflux disease and esophageal dysmotility are prevalent in patients with advanced lung disease and are associated with graft dysfunction following lung transplantation. As a result, many transplant centers perform esophageal function testing as part of the wait-listing process but guidelines for testing in this population are lacking. The aim of this study is to describe whether symptoms of gastroesophageal reflux correlate with abnormal results on pH-metry and high-resolution manometry and can be used to identify those who require testing. We performed a retrospective cohort study of 226 lung transplant candidates referred for high-resolution manometry and pH-metry over a 12-month period in 2015. Demographic data, results of a standard symptom questionnaire and details of esophageal function testing were obtained. Associations between the presence of symptoms and test results were analyzed using Fisher's exact tests and multivariable logistic regression. The most common lung disease diagnosis was interstitial lung disease (N = 131, 58%). Abnormal pH-metry was seen in 116 (51%) patients and the presence of symptoms was significantly associated with an abnormal study (p advanced lung disease, symptoms of gastroesophageal reflux increase the likelihood of elevated acid exposure on pH-metry but were not associated with dysmotility. Given the proportion of asymptomatic patients with abnormal studies and associated post-transplant risks, a practice of universal high-resolution manometry and pH-metry testing in this population is justifiable.

    Radiological evaluation of esophageal motility and the lower esophageal sphincter has gained increased attention in recent years. Videofluoroscopic investigation of esophageal motor function is superior to static film radiography, as repeated analysis of the videotaped recordings is possible. With emphasis on radiological techniques, normal esophagel physiology and motility and a variety of esophageal motor disorders are discussed in this review paper. Radiological evaluation of gastroesophageal reflux and reflux esophagitis is described. Clinical and radiological findings in esophageal motility disorders and gastroesophageal reflux disease and the radiological efficacy compared to that of manometry and pH-metry are discussed. (orig.)

    Gastroesophageal reflux disease (GERD) is prevalent worldwide, particularly in developed countries. It is estimated that the prevalence of GERD in the United States is approximately 20% and that it is increasing because of the epidemic of obesity. To review the pathophysiology, clinical presentation, diagnostic evaluation, and treatment of GERD. A search of PubMed was conducted for the years spanning 1985 to 2015 and included the following terms: heartburn, regurgitation, dysphagia, gastroesophageal reflux disease, cough, aspiration, laryngitis, GERD, GORD, endoscopy, manometry, pH monitoring, proton pump inhibitors, open fundoplication, and laparoscopic fundoplication. Only articles in English were included. Lifestyle modifications, proton pump inhibitors, and laparoscopic fundoplication are proven treatment modalities for GERD. Endoscopic procedures have not been proven as effective. A Roux-en-Y gastric bypass is the procedure of choice when GERD and morbid obesity coexist. Gastroesophageal reflux disease is a highly prevalent disease. Once the diagnosis has been established, the best results are obtained by a multidisciplinary team with the goal of individualizing treatment for patients.

    Full Text Available Raymond SY Tang, Justin CY Wu Institute of Digestive Disease, The Chinese University of Hong Kong, Prince of Wales Hospital, Shatin, New Territories, Hong Kong Abstract: 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.

  13. Reflux esophagitis triggered after Helicobacter pylori eradication: a noteworthy demerit of eradication therapy among the Japanese?

    2015-06-01

    Full Text Available In the February 2013 Revision of Insured Medical Treatment, bacterial eradication for all Helicobacter pylori-positive individuals in Japan was covered under the insurance scheme. However, reflux esophagitis is believed to occur in approximately 10% of Japanese patients who undergo eradication therapy. Hence, the risk of reflux esophagitis among such cases should be carefully considered, particularly in the treatment for H. pylori-positive patients who are otherwise healthy. The eradication of Helicobacter pylori in cases of H. pylori-positive gastritis markedly suppresses gastric inflammation, and inhibits gastric mucosal atrophy and its progression to intestinal metaplasia. In a long-term follow-up study (10-20 years, eradication treatment was found to reduce the risk of subsequent gastric cancer. However, the fact that eradication-induced reflux esophagitis could increase the long-term risk of Barrett’s esophagus and esophageal adenocarcinoma should also be considered in the Japanese population. Appropriate treatment with proton pump inhibitors should be taken into consideration for patients undergoing eradication therapy in clinical practice.

    The prevalence of gastroesophageal reflux disease in Korea has been believed to be low, but the incidence of gastroesophageal reflux disease in Korea is expected to increase because of the longer life expectancy and more ingestion of westernized food. The aim of this study was to report differences in the risk factors of reflux esophagitis (RE) according to age in Korea. We prospectively recruited the subjects who had RE among those who visited a health promotion center for upper gastrointestinal cancer surveillance at Hallym Medical Center (five institutions) between January 2008 and February 2009. The enrolled study participants comprised 742 subjects with RE and 1484 healthy controls. The independent risk factors of RE in young and adult group were male sex, smoking, coffee, body mass index ≥ 25, hiatal hernia, and Helicobacter pylori negativity. The risk factors of RE in elderly group were smoking, coffee, and hiatal hernia. The risk factors for RE according to age group were found to differ. In elderly group, Helicobacter pylori infection was not a significant protective factor contrary to young and adult groups. © 2012 Copyright the Authors.

    Gastroesophageal reflux disease has a variable presentation on upper endoscopy. Gastroesophageal reflux disease can be divided into 3 endoscopic categories: Barrett's esophagus, erosive esophagitis, and normal mucosa/nonerosive reflux disease (NERD). Each of these phenotypes behave in a distinct manner, in regards to symptom response to treatment, and risk of development of complications such as esophageal adenocarcinoma. Recently, it has been proposed to further differentiate NERD into 2 categories: those with and those without "minimal changes." These minimal changes include endoscopic abnormalities, such as villous mucosal surface, mucosal islands, microerosions, and increased vascularity at the squamocolumnar junction. Although some studies have shown that patients with minimal changes may have higher rates of esophageal acid exposure compared with those without minimal changes, it is currently unclear if these patients behave differently than those currently categorized as having NERD. The clinical utility of identifying these lesions should be weighed against the cost of the requisite equipment and the additional time required for diagnosis, compared with conventional white light endoscopy.

    Abstract To determine the relationship between baseline impedance levels and gastroesophageal reflux, we retrospectively enrolled 110 patients (54 men and 56 female; mean age, 51 ± 14 years) with suspected gastroesophageal reflux disease (GERD) who underwent 24-h multichannel intraluminal impedance and pH monitoring. Patients were stratified according to symptom (typical or atypical) and reflux types (acid reflux, nonacid reflux [NAR], or no abnormal reflux). Mean nocturnal baseline impedance (MNBI) were measured 3 cm (distal esophagus) and 17 cm (proximal esophagus) above the lower esophageal sphincter. Median distal esophageal MNBI was lower in the acid reflux group (1244 Ω; 647–1969 Ω) than in the NAR (2586 Ω; 1368–3666 Ω) or no abnormal reflux groups (3082 Ω; 2495–4472 Ω; all P < .05). Distal MNBI were negatively correlated with DeMeester score and acid exposure time. Atypical symptoms were more frequently associated with NAR than typical symptoms (P < .01). Among patients with positive symptom-association probability (SAP) for NAR, median proximal MNBI tended to be lower in patients with typical symptoms (median, 3013 Ω; IQR, 2535–3410 Ω) than in those with atypical symptoms (median, 3386 Ω; IQR, 3044–3730 Ω, P = .05). Thus, atypical GERD symptoms were more likely to be associated with NAR. The mucosal integrity of the proximal esophagus might be relatively impaired in GERD patients with typical symptoms for NAR.

    The aim of this study is to evaluate the usefulness of gastroesophageal reflux (GER) scintigraphy using the knee-chest (KC) position for the diagnosis of gastroesophageal reflux disease (GERD). The study subjects were 37 patients with GERD and 8 healthy volunteers (control group). Endoscopically observed esophageal mucosal breaks were evaluated with the Los Angeles classification. For GER scintigraphy, the subjects ingested liquid yogurt labeled with 99m Tc-diethylene triamine pentaacetic acid ( 99m Tc-DTPA) and water. Imaging was performed in the supine and KC position, and GER was graded as 1-4 according to the extent of GER assessed by scintigraphy. GER scintigraphy revealed no reflux in the control group (specificity: 100%). In the supine position, gastroesophageal reflux was observed in 49% of the patients with GERD, compared to 76% in the KC position. 21 of 23 (91%) patients with erosive esophagitis were shown to have GER with scintigraphy. GER scintigraphy revealed severe reflux (grade 3 or 4) (83%, 10/12) in the patients who had severe mucosal breaks (the Los Angels classification grade C or D). GER scintigraphy detected grade 1 or 2 reflux in 7 of the 14 patients who were endoscopically negative. There was a correlation between the endoscopically determined severity of mucosa and the reflux grade which was determined with GER scintigraphy. GER scintigraphy can detect gastroesophageal reflux with a high sensitivity in the KC position and might be a useful method in the screening and assessment of the severity of this disease. This method would be useful for the diagnosis of GERD in endoscopically negative patients. (author)

    To compare the effect of anti-reflux surgery (ARS) versus proton pump inhibitor therapy on lower oesophageal sphincter (LOS) function and oesophageal acid exposure in patients with chronic gastro-oesophageal reflux disease (GORD) over a decade of follow-up. In this randomised, prospective, multicentre study we compared LOS pressure profiles, as well as oesophageal exposure to acid, at baseline and at 1 and 10 years after randomisation to either open ARS (n = 137) or long-term treatment with omeprazole (OME) 20-60 mg daily (n = 108). Median LOS resting pressure and abdominal length increased significantly and remained elevated in patients operated on with ARS, as opposed to those on OME. The proportion of total time (%) with oesophageal pH acid exposure was normalised in both groups, with no significant differences, and bilirubin exposure was within normal limits. After 10 years, patients with or without Barrett's oesophagus did not differ in acid reflux control between the two treatment options. Open ARS and OME were both effective in normalising acid reflux into the oesophagus even when studied over a period of 10 years. Anatomically and functionally the LOS was repaired durably by surgery, with increased resting pressure and abdominal length.

    Highlights: • Behavior of a reflux condensation heat transfer was investigated for SBLOCA tests. • Behavior of the reflux condensate in HL, SG inlet plenum, and U-tubes were evaluated. • Concept of a steam moisturizing phenomenon was introduced and discussed. • Test data and MARS calculations were compared and discussed on the reflux condensate. - Abstract: The behavior of the reflux condensation heat transfer in a hot side steam generator (SG) U-tubes during a cold leg (CL) pipe and a direct vessel injection (DVI) line break in small break loss-of-coolant accident (SBLOCA) tests of the ATLAS facility was investigated including MARS code calculations. Among the SBLOCA tests, a 6″-CL pipe and 50%-DVI line break SBLOCA test were selected to investigate the behavior of the reflux condensation. A reflux condensation heat transfer seemed to occur from the time the SG U-tubes were half-empty to near the loop seal clearing (LSC). It was found that a transition regime existed between the reflux condensation heat transfer and reverse heat transfer. The remaining reflux condensate in SG U-tubes owing to the counter-current flow limit (CCFL) phenomenon and a separating effect of liquid carry-over and/or entrainment with steam moisturizing seemed to affect the thermal-hydraulic behavior of the transition regime. It was also found that the steam flowrate of the loop pipings and SG U-tubes seemed to have a strong effect on the duration time of the transition regime, e.g., a larger steam flowrate results in a longer duration. From a comparison of the reflux condensation behavior between the ATLAS tests and MARS code calculations, overall qualitative agreements were found between the two cases. The largest discrepancies were found in the SG inlet plenum water level between the two cases, and the authors suggest that the combination effects of the remaining reflux condensate in SG U-tubes and a separating effect of liquid carry-over and/or entrainment with steam

    We reviewed the characteristics of 25 pediatric patients (41 ureters) with primary vesico-ureteral reflux (VUR) who underwent anti-reflux surgery. The patients comprised 14 males and 11 females. The median age at diagnosis and at operation was 5 years 3 months and 6 years 5 months, respectively. VUR grade comprised grade I, 4 cases, grade II, 3 cases, grade III, 11 cases, grade IV, 11 cases and grade V, 12 cases. We utilized the Cohen method as the anti-reflux surgery technique. VUR recurrence was detected in 1 case (2.9%) during follow-up. Moreover, there were no cases with progressive renal dysfunction or breakthrough infection. The rate of kidney with renal scar on scintigraphy before the operation was 48.9%, and the rate of kidney with renal dysfunction before the operation was 60.0%. As a result of Fisher's exact probability test, the risk factors of breakthrough infection (BTI) were high grade VUR and renal scar on scintigraphy. Based on our clinical results, our future strategy for the management of pediatric patients with primary VUR is proposed as follows. In all patients younger than 1 year old, antibacterial prophylaxis should be applied. For patients younger than 6 years old, the initial treatment should be antibacterial prophylaxis, but for patients with VUR of grade III or more, in cases of breakthrough infection or in cases with progressive renal dysfunction, surgical treatment should be considered. For patients older than 6 years with VUR of grade III or more, surgical treatment is strongly recommended. (author)

    A noninvasive scintigraphic technique was used to estimate enterogastric reflux and subsequent gastric evacuation of refluxate in 35 normal, healthy subjects and 55 patients previously treated by vagotomy or partial gastrectomy. Reflux was provoked by a milk drink and quantitated by counting 99Tcm-EHIDA activity within the gastric area during gamma camera imaging. Seven normal subjects (20%) showed reflux of 5-18% of initial activity (mean: 10%), with peak values occurring at 5-30 minutes (mean: 14 minutes) following the milk. Gastric evacuation of activity in these subjects was monoexponential (r = 0.993, T1/2 = 24.1 minutes). Reflux occurred more frequently than normal in patients with truncal vagotomy and drainage (22/28 patients) and partial gastrectomy (20/21 patients). All of 16 patients with Billroth II anastomoses exhibited reflux, which was excessive compared with refluxing normal subjects (mean: 25%; p less than 0.01) and occurred later into the study (mean: 34 minutes; p less than 0.01). Ten of 11 asymptomatic patients showed reflux of similar amounts of activity (mean: 21%) compared with 16 patients who complained of bile vomiting (mean: 22%). However, asymptomatic patients exhibited gastric evacuation of refluxate at a rate similar to that of refluxing normal subjects, while bile vomiters showed significant gastric retention of refluxate at 25-30 minutes following peak gastric activity (p less than 0.05). This result confirms that post-operative bile vomiting is essentially a problem of gastric emptying

    Full Text Available Gastrostomy has been increasingly indicated for daily feeding ofneurologically impaired children with swallowing abnormalitiesthat hinder the use of the mouth. Therefore, the enteral route hasstill been used by means of oral, nasogastric or nasojejunal tube.However it is no longer the preferential method, mainly in cases ofprolonged use. Today gastrostomy is the most often utilizedprocedure, particularly Stamm gastrostomy. Many of thesepatients present pulmonary abnormalities due to a possiblegastroesophageal reflux (GER. After the study by Jolley et al.(1, in1985, fundoplication has become a systematic and routinecomplement to gastrostomy. The neurologically impaired patientshave been submitted to two surgeries, leading to possible andpredictable increase in morbidity and mortality rates. Althougheffective when properly indicated, this simple management hasrecently been very much debated and rejected. Thus, an updatingbased on recent studies is necessary to make pediatric surgeonsand pediatricians aware of other manners to solve this problem,which aim at correctly feeding these children with impairedswallowing and GER and helping them have a better quality of life.The literature reviewed was searched in PubMed/Medline, fromJanuary 1994 to May 2003. Other articles read and mentioned inthis review and published before 1994 were collected based onarticles cited in the references. Thus, we could assess thechronological progression in management of neurologicallyimpaired children who need gastrostomy for their feeding, andcarry out an analysis of current fundoplication and the questionwhether the use of a prophylactic antireflux valve is compulsoryor not.

    Ulceration of the oesophageal squamous mucosa (ulcerative oesophagitis) is a pathological manifestation of gastro-oesophageal reflux disease, and is a major risk factor for the development of Barrett's oesophagus. Barrett's oesophagus is characterised by replacement of reflux-damaged oesophageal squamous epithelium with a columnar intestinal-like epithelium. We previously reported discovery of microRNAs that are differentially expressed between oesophageal squamous mucosa and Barrett's oesophagus mucosa. Now, to better understand early steps in the initiation of Barrett's oesophagus, we assessed the expression, location and function of these microRNAs in oesophageal squamous mucosa from individuals with ulcerative oesophagitis. Quantitative real-time PCR was used to compare miR-21, 143, 145, 194, 203, 205 and 215 expression levels in oesophageal mucosa from individuals without pathological gastro-oesophageal reflux to individuals with ulcerative oesophagitis. Correlations between microRNA expression and messenger RNA differentiation markers BMP-4, CK8 and CK14 were analyzed. The cellular localisation of microRNAs within the oesophageal mucosa was determined using in-situ hybridisation. microRNA involvement in proliferation and apoptosis was assessed following transfection of a human squamous oesophageal mucosal cell line (Het-1A). miR-143, miR-145 and miR-205 levels were significantly higher in gastro-oesophageal reflux compared with controls. Elevated miR-143 expression correlated with BMP-4 and CK8 expression, and elevated miR-205 expression correlated negatively with CK14 expression. Endogenous miR-143, miR-145 and miR-205 expression was localised to the basal layer of the oesophageal epithelium. Transfection of miR-143, 145 and 205 mimics into Het-1A cells resulted in increased apoptosis and decreased proliferation.

    It has been suggested that gastroesophageal reflux scintigraphy might be useful in assisting one in determining therapy for patients suspected of aspirating or becoming apneic secondary to gastroesophageal reflux. This, however, has not been our experience and in reviewing 23 patients with recurrent pneumonia and/or apnea who had gastroesophageal reflux scintigraphy, we were able to detect aspiration in only one. This was especially significant since 13 (59%) of these patients had demonstrable reflux, and of these, eight were treated successfully for suspected aspiration even though none was demonstrated isotopically. To be sure, the demonstration of pulmonary aspiration with gastroesophageal reflux scintigraphy had little influence on patient selection and response to therapy. For this reason we feel there is little justification in depending on the GRS for the specific purpose of trying to document pulmonary aspiration in infants and children who are refluxing. One of the more serious complications of gastroesophageal (GE) reflux is aspiration leading to recurrent pulmonary infections and/or apnea. However, it always has been difficult to demonstrate actual aspiration into the lungs, and to be sure, barium studies of the upper GI tract seldom reveal this complication. Recently, however, considerable interest has been generated in gastroesophageal scintigraphy (GRS) as a possible means of documenting such aspiration. Rationale for this stems from the fact that suspected patients can be studied over a longer period of time and in addition, delayed and overnight images can be obtained. However, our experience does not support GRS as being an adequate method for demonstrating aspiration. (orig.)

    To study the incidence and pattern of gastro-oesophageal reflux disease (GORD) in patients with mild-to-moderate chronic obstructive pulmonary disease (COPD) using dual-probe 24-h oesophageal pH recording. This was a prospective study of 50 patients with mild-to-moderate stage COPD based on the Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines. A detailed history of illness along with spirometry was done in all patients. In the study group, reflux symptoms were measured using a validated scoring system. All the patients underwent oesophageal manometry and dual-probe 24-h oesophageal pH recording. Symptoms of gastro-oesophageal reflux were present in 38 patients. Twenty-four-hour oesophageal pH monitoring revealed pathological reflux in 31 out of 38 symptomatic and 8 out of 12 asymptomatic patients. The overall rate of GORD was 78% in our study. Only distal GORD was observed in 11 (28.9%), and both distal and proximal GORD was observed in 20 (52.6%) out of the 38 symptomatic subjects. In the remaining 12 asymptomatic patients, eight had GORD. Distal GORD was present in six (50%) patients, and two (16.6%) had both distal and proximal GORD in this group. Isolated proximal GORD was not observed in any patient. There is an increased occurrence of GORD in patients with even mild-to-moderate COPD. © 2013 The Authors.

    Excessive supragastric belching (SGB) manifests as troublesome belching, and can be associated with reflux and significant impact on quality of life (QOL). In some GERD patients, SGB-associated reflux contributes to up to 1/3 of the total esophageal acid exposure. We hypothesized that a cognitive-behavioral intervention (CBT) might reduce SGB, improve QOL, and reduce acid gastroesophageal reflux (GOR). We aimed to assess the effectiveness of CBT in patients with pathological SGB. Patients with SGB were recruited at the Royal London Hospital. Patients attended CBT sessions focused on recognition of warning signals and preventative exercises. Objective outcomes were the number of SGBs, esophageal acid exposure time (AET), and proportion of AET related to SGBs. Subjective evaluation was by patient-reported questionnaires. Of 51 patients who started treatment, 39 completed the protocol, of whom 31 had a follow-up MII-pH study. The mean number of SGBs decreased significantly after CBT (before: 116 (47-323) vs. after 45 (22-139), P50%. In patients with increased AET at baseline, AET after CBT was decreased: 9.0-6.1% (P=0.005). Mean visual analog scale severity scores decreased after CBT (before: 260 (210-320) mm vs. after: 140 (80-210) mm, Pacid reflux predominantly driven by SGB. In these patients, CBT can reduce esophageal acid exposure.

    The function and structure of the gastro-esophageal junction (GEJ) determine its efficacy as a reflux barrier. This study presents a novel methodology for the quantitative assessment of GEJ and proximal gastric morphology from magnetic resonance (MR) imaging. Based on this data we propose a new conceptualization of the hypothesis that a flap valve mechanism contributes to reflux protection. 3D models of the GEJ and proximal stomach were reconstructed from MR images in 12 healthy volunteers during respiration and on eating a test meal to maximum satiation. A rotating plane analysis measured the gastro-esophageal insertion angle and span of contact. An ellipsoid fit provided quantitative assessment of gastric shape and orientation relative to a fixed anatomical reference point. Position of the esophageal insertion on the 'gastric ellipse' was noted. An ellipsoid-cylinder model was designed to analyze the relationships among parameters describing the GEJ morphology. The insertion angle became more acute on expiration, but did not change with meal ingestion. In contrast the span of contact did not vary with respiration, but increased with gastric filling. Changes in gastric morphology with distension further augmented the span of gastro-esophageal contact in almost 70% of the studies. Novel MR imaging and biophysical analysis of the GEJ and proximal stomach provide a quantitative description of structures contributing to the reflux barrier. Changes in these parameters during respiration and on eating support the hypothesis that structural components of a functional 'flap valve' like mechanism contribute to reflux protection. © 2012 Blackwell Publishing Ltd.

    Gastro-esophageal reflux (GER), particularly non-acid reflux, is common in infants and is a known cause of chronic respiratory symptoms in infancy. Recent guidelines recommended empirical acid suppression therapy and the head-up position in patients with suspected GER. However, the efficacy of the upright position in relieving GER and reflux-related respiratory symptoms in infants is unclear. We conducted this study to investigate the efficacy of the upright position on GER and reflux-related respiratory symptoms in infants with chronic respiratory symptoms. Thirty-two infants (21 male; median age, 5 months; range, 0 to 19 months) with unexplained chronic respiratory symptoms underwent multi-channel intraluminal esophageal impedance and pH monitoring. We retrospectively compared the frequencies of GER and reflux-related symptoms according to body position. A mean of 3.30 episodes of reflux per hour was detected. Overall, refluxes were more frequent during the postprandial period than the emptying period (3.77 vs. 2.79 episodes/hour, respectively; P=0.01). Although there was no significant difference in the total refluxes per hour between the upright and recumbent positions (6.12 vs. 3.77 episodes, P=0.10), reflux-related respiratory symptoms per reflux were significantly fewer in infants kept in an upright position than in a recumbent position during the postprandial period (3.07% vs. 14.75%, P=0.016). Non-acid reflux was the predominant type of reflux in infants, regardless of body position or meal time. The upright position may reduce reflux-related respiratory symptoms, rather than reflux frequency. Thus, it may be a useful non-pharmacological treatment for infantile GER disease resistant to acid suppressants.

    Full Text Available AimTo find the trend in patient’s visits to our centers for vesicoureteral reflux (VUR. We hypothesize that VUR diagnosis and hence possible nephropathy recognition may be diminishing because of changing practice patterns.MethodsData were extracted from electronic medical records for new and follow-up patients aged 0–18 years with ICD-9/10 codes to correspond with VUR, VUR unilateral, VUR bilateral, and VUR with reflux nephropathy, as well as new patients with diagnoses of urinary tract infections (UTI and pyelonephritis at two major pediatric centers from 2012 to 2015. Figures and statistics to reflect absolute clinic visits and annual trends were created with SPSS 2010. Linear regression was applied.ResultsAnnually, Le Bonheur Children’s Hospital and Nationwide Children’s Hospital experienced an average decrease of 13 and 17% in total VUR visits, and an average decrease of 22 and 27% in VUR nephropathy visits, respectively, for each institution. Patient visits for UTIs were reduced an average of 16% annually in both centers. Linear regression demonstrated that number of patients (patients/year ± SE decreased annually 69 ± 19 (P = 0.02, 7 ± 2 (P = 0.02, and 67 ± 25 (P = 0.04 for VUR, VUR nephropathy, and UTI, respectively.ConclusionWe conclude that the decreased number of VUR and VUR nephropathy cases identified in subspecialty clinics (Nephrology/Urology at two major children’s hospitals reflect a possible decreased identification of VUR. This trend may also be due to decreased referral of low grade cases of VUR. We cannot conclude that “undifferentiated UTI” referrals increased concomitantly to account for the decreased VUR as our data reflects a decreased trend in those visits as well. We suggest that clinicians following the American Academy of Pediatrics guidelines ensure that all UTI are accounted for and surveillance is appropriately escalated for recurrent UTI or abnormal imaging results.

    The cause of idiopathic pulmonary fibrosis (IPF) remains unknown, yet gastro-esophageal reflux disease (GERD) is highly prevalent in this population. GERD prevalence was studied, and esophageal function tests (EFT) were assessed in Chinese IPF patients. We prospectively studied 69 IPF patients who undertook both stationary High Resolution esophageal Manometry/Impedance (HRiM) and 24-hour esophageal Multi-Channel Intraluminal Impedance with pH Recordings (MII/pH). Patients were divided into GERD+ and GERD- groups according to pH results. Controls were HRiM treated healthy volunteers, and patients without IPF received HRiM and MII/pH diagnosed with GERD. 69 IPF patients, 62 healthy volunteers, and 88 IPF negative GERD patients were selected. GERD prevalence in IPF was 43/69 (62.3%), and 58.1% of patients presented with at least one typical symptom. Symptoms had a sensitivity of 58.1%, a specificity of 61.6%, a positive predictive value of 71.4% and a negative predictive of 47.1%. Compared with healthy volunteers, IPF patients had significantly decreased lower esophageal sphincter pressure (LESP), upper esophageal sphincter pressure (UESP) and complete bolus transit rate (CBTR). By contrast, IPF patients had increased total bolus transit time and prevalence of weak peristalsis. MII/pH showed that one third of IPF patients had abnormal distal and proximal reflux, especially non-acid reflux. Compared with GERD patients without IPF, GERD patients with IPF had significantly decreased CBTR and UESP with increased bolus exposure time. GERD prevalence in IPF was high, but symptoms alone were an unreliable predictor of reflux. IPF patients had lower LESP and UESP, impaired esophageal peristalsis and bolus clearance function with more proximal reflux events.

    Objective: The relationship between gastroesophageal reflux disease (GERD) and gastric emptying rate was investigated. Results of endoscopy, 24-hour esophageal pH monitoring were also evaluated. Methods: 15 patients were evaluated with endoscopy, pH monitoring and radionuclide gastric emptying. The results were compared with that of 17 control subjects. Correlations of gastric emptying rate and esophagitis, 24-hour pH monitoring between GERD patients and control subjects were also analyzed. Results: Liquid gastric emptying rate of GERD patients was significantly lower than that of control subjects at 15 and 30 min (P 0.05), but there exhibited a linear correlation between 50% solid emptying time and esophagus pH total score (r=0.643, P<0.05). Conclusions: The results indicate a delayed liquid and solid gastric emptying in GERD patients. There is a linear correlation between 50% solid emptying time and esophagus pH total score. Delayed gastric emptying may be an important factor in the pathogenesis of GERD

    An acid perfusion test, isotope scanning, endoscopy, and esophageal biopsy were performed in 101 patients with symptoms strongly suggestive of gastroesophageal reflux (GER) disease. A positive acid perfusion test within 30 min (APT) and within 5 min (TAPT) was found in 70.2% and 37.6% of the patients, respectively. A positive APT was found significantly more often in patients with than without endoscopic esophagitis, whereas a positive TAPT was found significantly more often in patients with severe symptoms than in patients with moderate symptoms, and in a significantly higher proportion of patients with than without GER by scintigraphy. Neither the APT nor the TAPT showed any dependency on the presence of histologic esophagitis. Most (97%) patients with a negative acid perfusion test, in addition to typical symptoms, also presented with scintigraphic, endoscopic, or histologic evidence of GER disease. Although it shows that the acid perfusion test, particularly when early positive, may serve as a weak predictor of the severity of GER disease, the present study gives little support to the test's clinical usefulness.

    Gastroesophageal reflux is considered a risk factor for recurrent or persistent upper and lower respiratory tract conditions including asthma, chronic cough, sinusitis, laryngitis, serous otitis and paroxysmal laryngospasm. Fifty-one subjects with recurrent (more than three) episodes of upper respiratory tract infection (URTI), serous otitis or sinusitis who had been admitted to an earnose- throat (ENT) outpatient clinic during the previous year were enrolled in the present study to evaluate the presence of laryngeal and/or esophageal reflux. The participants, who were randomly selected, were questioned about symptoms of reflux, including vomiting, abdominal pain, failure to thrive, halitosis, bitter taste in the mouth, chronic cough, heartburn, constipation and hoarseness. All subjects had an endoscopic examination, an otoscopic examination, a tympanogram and upper GI system endoscopy. Esophagitis was diagnosed endoscopically and histologically. The likelihood of occurrence of esophagitis was found to be higher only among subjects with postglottic edema/erythema as determined by pathological laryngeal examination. The reflux complaints reported did not predict the development of esophagitis, but the odds of esophagitis occurring were ninefold greater among subjects with recurrent otitis. Of the subjects, 45.1% were Helicobacter pylori-positive. However, no association was found between esophagitis and Helicobacter pylori positivity. The likelihood of the occurrence of esophagitis was found to be increased in the presence of recurrent otitis media and/or postglottic edema, irrespective of the presence of reflux symptoms. We concluded that, in contrast to the situation where adults are concerned, the boundaries for discriminating laryngopharyngeal reflux from gastroesophageal reflux are somewhat blurred in pediatric patients.

    Lung transplantation is one of the highest risk solid organ transplant modalities. Recent studies have demonstrated a relationship between gastroesophageal reflux disease (GERD) and lung transplant outcomes, including acute and chronic rejection. The aim of this review is to discuss the pathophysiology, evaluation, and management of GERD in lung transplantation, as informed by the most recent publications in the field. The pathophysiology of reflux-induced lung injury includes the effects of aspiration and local immunomodulation in the development of pulmonary decline and histologic rejection, as reflective of allograft injury. Modalities of reflux and esophageal assessment, including ambulatory pH testing, impedance, and esophageal manometry, are discussed, as well as timing of these evaluations relative to transplantation. Finally, antireflux treatments are reviewed, including medical acid suppression and surgical fundoplication, as well as the safety, efficacy, and timing of such treatments relative to transplantation. Our review of the data supports an association between GERD and allograft injury, encouraging a strategy of early diagnosis and aggressive reflux management in lung transplant recipients to improve transplant outcomes. Further studies are needed to explore additional objective measures of reflux and aspiration, better compare medical and surgical antireflux treatment options, extend follow-up times to capture longer-term clinical outcomes, and investigate newer interventions including minimally invasive surgery and advanced endoscopic techniques.

    Gastroesophageal reflux disease is a common disorder affecting children worldwide. The objective of this study is to report our experience on the accuracy of tests used for the diagnosis ofgastroesophageal reflux disease with emphasis on the advantages and disadvantages of each of them. This study took place in the Pediatric Gastroenterology Division, Department of Pediatrics, College of Medicine and King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia, during the period of 1994 through to 1999. Results of barium meal, 24-hour esophageal pH monitoring, endoscopy, and gastrointestinal scintigraphy are analyzed and compared in children with and without gastroesophageal reflux disease. One hundred and forty-four children were investigated. The diagnosis was confirmed in 85 and excluded in 59 children, who will be considered as patients without gastroesophageal reflux disease. The results of barium meal, 24 hour pH monitoring, endoscopy, and gastrointestinal scintigraphy were positive in 80%, 78%, 92%, and 70% of the patients with gastroesophageal disease. The same studies were falsely positive in 29%, 9%, 19%, and 0% of those without gastroesophageal reflux disease. Esophageal pH was the most specific diagnostic study (91%), whereas endoscopy was the most sensitive (92%) and had the best positive predictive value (95%). The results of this study are similar to reports from other parts of the world. It is stressed that all procedures have important advantages and disadvantages indicating that the selection of procedures should be individualized and based on the clinical situation. (author)

    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.

    While delayed solid gastric emptying (GE) has been reported in patients with gastroesophageal reflux (GER), the relationship of GE to daytime and/or nighttime reflux patterns, and the severity of endoscopic esophagitis are unknown. The authors measured GE in a study population of symptomatic patients (n=33) with abnormal 24 hour pH monitoring (24 hr pH). The study population was divided into two groups by esophagoscopy; those with (E+=22); and 2) those without (E-=11) erosive esophagitis and/or Barrett's esophagus. GE was measured in all patients and in 15 normal volunteers (NL) by the in vivo labelling of chicken liver with Tc-99m-SC, which was in turn diced into 1 cm. cubes and given in 7 1/2 oz. of beef stew. Upright one minute anterior and posterior digital images were obtained every 15 min. for 2.5 hours. 24 hour pH was divided into daytime (upright) and nighttime (supine) segments, and acid exposure was defined as % time pH < 4 for that posture. There was no correlation between GE T 1/2 and acid exposure, daytime or nighttime, for the patient population as a whole. However, patients with the longest GE T1/2 tended to have severe daytime reflux. The authors rarely found delayed solid food gastric emptying in patients with reflux; moreover, they found no association between GE and either diurnal reflux patterns on 24 hr pH or the severity of endoscopic esophagitis

    There continues to be significant controversy related to diagnostic testing for gastroesophageal reflux disease (GERD). Clearly, barium contrast fluoroscopy is superior to any other test in defining the anatomy of the upper gastrointestinal (UGI) tract. Although fluoroscopy can demonstrate gastroesophageal reflux (GER), this observation does not equate to GERD. Fluoroscopy time should not be prolonged to attempt to demonstrate GER during barium contrast radiography. There are no data to justify prolonging fluoroscopy time to perform provocative maneuvers to demonstrate reflux during barium contrast UGI series. Symptoms of GERD may be associated with physiologic esophageal acid exposure measured by intraesophageal pH monitoring, and a significant percentage of patients with abnormal esophageal acid exposure have no or minimal clinical symptoms of reflux. Abnormal acid exposure defined by pH monitoring over a 24-h period does not equate to GERD. In clinical practice presumptive diagnosis of GERD is reasonably assumed by substantial reduction or elimination of suspected reflux symptoms during therapeutic trial of acid reduction therapy.

    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 tolerance to stress and higher frustration, fear, and worry. On the basis of such unfavorable phychoemotional results observed with GERD patients (especially those without hernia) in the different tests, we propose that improving our knowledge of the psychological profile of GERD patients - particularly those without hiatal hernia - could help in designing individualized medical and psychological therapies and increase success rates. © 2012 Copyright the Authors.

    Full Text Available Gastroesophageal reflux disease (GORD is an often debilitating condition characterised by retrograde flow of content from stomach into the oesophagus, where the low pH of the stomach acid irritates the mucosa of the oesophagus. The most dominant symptoms in GORD are pyrosis, regurgitation, and dysphagia. Sublingual immunotherapy (SLIT was first described in 1986. Following this description, the use has greatly increased in the treatment of allergic rhinitis, as an alternative to subcutaneously administered immunotherapy. Side effects are commonly of oropharyngeal and gastrointestinal nature, for example, swelling, itching, irritation, ulceration of the oropharynx and nausea, abdominal pain, vomiting, and diarrhoea. More serious side effects are dominated by respiratory tract and systemic manifestations. A 30-year-old male experienced refractory, relentless, and debilitation GORD subsequent to administration of sublingual immunotherapy for house dust mite in allergic rhinitis. The patient had to stop the SLIT after two weeks of administration due to GORD. The cessation resulted in rapid resolution of symptoms.

  5. Histologic definition of gastro-esophageal reflux disease.

    To review recent data supporting the development of new histology-based definitions of gastro-esophageal reflux disease (GERD). Three precisely definable columnar epithelial types--cardiac, oxyntocardiac and intestinal--may be interposed between esophageal squamous epithelium and gastric oxyntic (acid secreting) mucosa. This enables definition of a new histologic concept: the squamo-oxyntic gap. The squamo-oxyntic gap is zero or very small in autopsies performed on patients without evidence of GERD. The gap progressively increases in length with the severity of GERD, indicating that the squamo-oxyntic gap is a marker for chronic GERD. The distal part of the gap lines gastric-type rugal folds and, therefore, is distal to the present endoscopic definition of the gastro-esophageal junction. I contend that this distal gap segment (which has esophageal submucosal glands) is actually the dilated distal esophagus; this is the pathologic correlate of destruction of the abdominal segment of the lower esophageal sphincter. The dilated distal esophagus is mistaken for 'gastric cardia' by present endoscopic definitions. I believe that these data support the adoption of novel histologic definitions of GERD as follows: the presence of any squamo-oxyntic gap defines GERD; the length of the gap is a measure of severity of chronic GERD; and the presence of intestinal metaplasia in the gap defines Barrett esophagus and cancer risk.

    There are many articles about the role of barium esophagography for the diagnosis of gastroesophageal reflux disease. However, there are only rare articles reporting on laryngopharyngeal reflux disease. The purpose of this study is to evaluate the usefulness of performing esophagography with the water-siphon test as an initial screening test for patients with suspected laryngopharyngeal reflux. From October 2002 to December 2004, barium esophagography with the water-siphon test was performed for 707 patients who had the typical symptoms and telescopic findings of laryngopharyngeal reflux. The results of the 707 esophagograms (the group with laryngopharyngeal reflux) were compared with those of 122 patients who were confirmed as having gastroesophageal reflux upon performing pH-metry (the group with gastroesophageal reflux) and the 324 patients without laryngopharyngeal reflux symptoms (the control group). The results of the water-siphon test were classified into normal, mild, moderate and severe degrees of gastroesophageal reflux. On the water-siphon test for the laryngopharyneal reflux group patients, 71 patients had normal (10.0%), 207 had mild (29.2%), 201 had moderate (28.4%) and 228 had severe (32.2%) degrees of reflux. The positive rates of the water-siphon test were 90.0%, 89.3% and 54.6% for the groups with laryngopharyngeal reflux, gastroesophageal reflux and the control group, respectively. A statistically significant difference was observed between the group with laryngopharyngeal reflux and the control group, and between the group with gastroesophageal reflux and the control group, respectively (ρ < 0.05). Esophagography with the water-siphon test is useful as an initial screening test for laryngopharyngeal reflux disease

    Esophageal reflux symptom has been reported as common in patients with subtotal gastrectomy. Management of postoperative esophageal reflux symptom is not satisfactory. The aim of this study is to investigate prevalence of esophageal reflux symptom after subtotal gastrectomy and assess factors affecting esophageal reflux symptom in subtotal gastrectomy patients. We prospectively enrolled 100 consecutive patients with subtotal gastrectomy who were regularly followed up by endoscopic examination. Acid secretory capacity was assessed by measuring messenger RNA (mRNA) expression of H + /K + -adenosine triphosphatase (ATPase) via real-time polymerase chain reaction (PCR) in biopsy specimens. In total, 47 % of patients had typical esophageal reflux symptom, where heartburn or regurgitation was experienced at least weekly. Age, sex, body mass index, and type of reconstruction did not differ between esophageal reflux and non-esophageal-reflux groups. The esophageal reflux group had longer duration from time of operation until study (median 5.0 versus 3.6 years; P = 0.017). Hill grade for gastroesophageal (GE) flap valve was higher in the esophageal reflux group than in the non-esophageal-reflux group (P = 0.027). H + /K + -ATPase mRNA expression was higher in the esophageal reflux group than in the non-esophageal-reflux group [3967.6 (± 7583.7) versus 896.2 (± 1456.0); P = 0.006]. Multivariate analysis revealed that postoperative duration, H + /K + -ATPase mRNA expression level, and GE flap valve disruption were significantly associated with esophageal reflux symptom development. Esophageal reflux symptom is common in patients after subtotal gastrectomy, possibly because of anti-reflux-barrier impairment and preservation of acid secretory capacity following surgery. Optimal acid suppression may be helpful in managing postoperative esophageal reflux symptom.

    The objective of the present study was to determine if there is correlation between signs of reflux laryngitis (RL) and reflux oesophagitis (RE) in patients with gastro-oesophageal reflux disease (GORD) symptoms. Laryngeal photography obtained from patients during oesophagogastroduodenoscopy were examined by two otolaryngologists experienced in the field of extra-oesophageal reflux regarding the presence and severity of RL. The presence of RE was evaluated by gastroenterologist. Smokers, heavy drinkers and patients with bronchial asthma were excluded from the statistical analysis. A total of 681 patients were analysed. RL was diagnosed in 367 (53.9%) cases, of whom 182 patients had mild, 118 moderate and 67 severe (Reflux Finding Score > 7) RL. RE was diagnosed in 103 (28.1%) patients with RL and in 80 (25.7%) patients without RL. Neither the difference between the overall group of patients with RL and those without (OR 1.141, 95% CI 0.811-1.605, p = 0.448), nor the differences between the respective subgroups of patients with mild, moderate and severe RL and those without RL were statistically significant. The OR and 95% CI for mild, moderate and severe RL were 1.042, 95% CI 0.712-1.526, p = 0.834, 1.182, 95% CI 0.764-1.831, p = 0.453 and 1.0, 95% CI 0.566-1.766, p = 0.999 respectively. It can be concluded that there is no correlation between RL and RE in patients with GORD symptoms. © Copyright by Società Italiana di Otorinolaringologia e Chirurgia Cervico-Facciale, Rome, Italy.

    Full Text Available Abstract Background Several studies have reported an association between asthma and gastro-oesophageal reflux, but it is unclear which condition develops first. The role of obesity in mediating this association is also unclear. We explored the associations between respiratory symptoms, lung function, and gastro-oesophageal reflux symptoms in a birth cohort of approximately 1000 individuals. Methods Information on respiratory symptoms, asthma, atopy, lung function and airway responsiveness was obtained at multiple assessments from childhood to adulthood in an unselected birth cohort of 1037 individuals followed to age 26. Symptoms of gastro-oesophageal reflux and irritable bowel syndrome were recorded at age 26. Results Heartburn and acid regurgitation symptoms that were at least "moderately bothersome" at age 26 were significantly associated with asthma (odds ratio = 3.2; 95% confidence interval = 1.6–6.4, wheeze (OR = 3.5; 95% CI = 1.7–7.2, and nocturnal cough (OR = 4.3; 95% CI = 2.1–8.7 independently of body mass index. In women reflux symptoms were also associated with airflow obstruction and a bronchodilator response to salbutamol. Persistent wheezing since childhood, persistence of asthma since teenage years, and airway hyperresponsiveness since age 11 were associated with a significantly increased risk of heartburn and acid regurgitation at age 26. There was no association between irritable bowel syndrome and respiratory symptoms. Conclusion Reflux symptoms are associated with respiratory symptoms in young adults independently of body mass index. The mechanism of these associations remains unclear.

    Gastro-oesophageal reflux symptoms are usually reported by patients with obesity and metabolic syndrome. Aim of this study was to assess the prevalence and clinical characteristics of gastro-oesophageal reflux symptoms in subjects with non-alcoholic fatty liver disease. Cross-sectional, case-control study of 185 consecutive patients with non-alcoholic fatty liver disease and an age- and sex-matched control group of 112 healthy volunteers. Participants were interviewed with the aid of a previously validated questionnaire to assess lifestyle and reflux symptoms in the 3 months preceding enrolment. Odds ratios were determined before and after adjustment for body mass index, increased waist circumference, physical activity, metabolic syndrome and proton pump inhibitors and/or antiacid medication. The prevalence of heartburn and/or regurgitation and of at least one of gastro-oesophageal reflux symptoms was significantly higher in the non-alcoholic fatty liver disease group. Non-alcoholic fatty liver disease subjects were associated to higher prevalence of heartburn (adjusted odds ratios: 2.17, 95% confidence intervals: 1.16-4.04), regurgitation (adjusted odds ratios: 2.61, 95% confidence intervals: 1.24-5.48) and belching (adjusted odds ratios: 2.01, 95% confidence intervals: 1.12-3.59) and had higher prevalence of at least one GER symptom (adjusted odds ratios: 3.34, 95% confidence intervals: 1.76-6.36). Non-alcoholic fatty liver disease is associated with a higher prevalence of gastro-oesophageal reflux symptoms. Copyright © 2012 Editrice Gastroenterologica Italiana S.r.l. Published by Elsevier Ltd.

    Thirty-seven adults with gastroesophageal reflux were explored by oesophageal scintigraphy and pH monitoring (three hours postprandial). Scintigraphy was less frequently positive than pH test in gastroesophageal reflux (81% versus 57%) with a significant difference. It is suggested that postprandial pH monitoring is reliable in the initial assessment of symptomatic gastroesophageal reflux.

    Full Text Available Background. A possible association of esophageal reflux disease with peptic ulcer, Helicobacter pylori infection or the results of eradication, has not been elucidated. It is an alarming fact that in developed countries the incidence of esophageal adenocarcinoma, which is associated with reflux disease, is increasing.Aim. The aim of the study was to establish the prevalence of esophageal reflux disease after eradication of H. pylori infection in patients with hemorrhaging and nonhemorrhaging peptic ulcer of stomach or duodenum.Patients and methods. Study was approved in 1998 by the Slovenian Medical Ethics Committee (No. 90/09/98. Prospective, controlled and randomized, carried out between 1998– 2000.The study included 80 patients (50 male and 30 female, av. age 57.5 years, SD ± 17.1, range 22–80 years in which endoscopy confirmed hemorrhage from peptic ulcer of stomach or duodenum and HP infection. The control group was made up of 80 patients (50 male and 30 female, av. age 56.8 years, SD ± 16.8, range 19–80 years with peptic ulcer of stomach or duodenum and H.pylori infection in the same period of time. In all cases the recommended drug combinations were used in the treatment of the infection: a proton pump inhibitor, omeprazol (4 weeks, and combination of antibiotics, claritromycin and metronidazole or with regard to the antibiogram (1 week. The therapeutic success was ascertained endoscopically four weeks after inclusion in the study. Infection eradication was confirmed by the rapid urease test and histologic investigation of the gastric mucosa. One year later, in the course of follow-up, in patients with endoscopic investigations, 24-hour pH-metry or fiberoptic spectrophotometric bilirubin determination, bilimetry, we tried to establish signs of esophageal reflux disease.Results. Four weeks after inclusion in the study the success of infection eradication was 92.5% in the study group while in the control group reached 91.25%, p > 0

    In a study comprising 100 patients referred to a surgical clinic with symptons suggestive of gastro-oesophageal reflux disease, the value of different diagnostic procedures was investigated. Positive acid perfusion and 24-h pH tests were the commonest findings. Forty-nine per cent showed normal oesophageal mucosa or diffuse oesophagitis at endoscopy. The severity of heartburn and regurgitation did not differ between patients with normal oesophageal mucosa and oesophagitis of various severities. The severity of macroscopic oesophagitis was significantly corelated to the total reflux time, the presence of reflux or a hiatal hernia at radiology, an open cardia or reflux at endoscopy, pressure transmission or reflux, and low lower oesophageal sphincter pressure at manometry. Gastric hypersecretion was found in 66% of the patients. Gastric acid secretion was not correlated to the severity of oesophagitis or to the findings at 24-h pH test. In patients with severe oesophagitis the sensivity for radiologic, manometric and endoscopic signs of incompetence of the gastro-oesophageal junction was 94%.

    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. (orig.)

    A detailed critique of objective measurements of gastroesophageal reflux disease (GERD) would improve management of patients suspecting of having reflux, leading to rational selection of treatment and better outcomes. Many diagnostic tests for GERD have been developed over the past decades. We analyze their development, positive- and negative-predictive values, and ability to predict response to treatment. These features are important for development of medical, surgical, and endoscopic therapies for GERD. We discuss the value of available diagnostic tests and review their role in management of patients with persistent reflux symptoms despite adequate medical or surgical treatment. This is becoming a significant health economic problem, due to the widespread use of proton pump inhibitors. GERD is believed to cause nonesophageal symptoms, such as those provoked by ear, nose, throat, or respiratory disorders. We analyze the value of GERD diagnostic tests in evaluation of these troublesome, nonesophageal symptoms. Copyright © 2018 AGA Institute. Published by Elsevier Inc. All rights reserved.

    The voiding cystourethrogram (VCUG) is a widely used study to define lower urinary tract anatomy and to diagnose vesicoureteric reflux (VUR) in children. We examine the technical advances in the VCUG and other examinations for reflux that have reduced radiation exposure of children, and we give recommendations for the use of imaging studies in four groups of children: (1) children with urinary tract infection, (2) siblings of patients with VUR, (3) infants with antenatal hydronephrosis (ANH), and (4) children with a solitary functioning kidney. By performing examinations with little to no radiation, carefully selecting only the children who need imaging studies and judiciously timing follow-up examinations, we can reduce the radiation exposure of children being studied for reflux.

    The paper describes a project carried out at Dawes Lane coking plant (in Scunthorpe, UK) to access current performance of the batch reflux system with respect to the operation of personnel and to recommend a solution to eliminate naphthalene blockage and problems previously caused by the use of hot debenzolised oil (DBO) as make-up. A successful solution was found and implemented. The benzole product now being produced is within specification and regularly achieves the composition produced by the previous hot reflux system (83% benzole, 7% naphthalene) with an addition reduction in wash oil usage of 20%. Problems of naphthalene blockages in reflux pipework have been cured. The expenses on the project were small. The paper was presented at a COMA meeting at Monckton Coke Ovens on 19 May 2005. 6 figs.

    Full Text Available Symptomatic gastroesophageal reflux is a common complication of pregnancy and lactation. However, the safety of many effective medical therapies, including oral proton pump inhibitors, has not been well defined. The administration of oral omeprazole to a 41-year-old female during the third trimester of pregnancy, after ranitidine and cisapride failed to control her refractory gastroesophageal reflux, is reported. No adverse fetal effects were apparent, and the patient elected to continue omeprazole therapy (20 mg/day while breastfeeding. Peak omeprazole concentrations in breast milk (58 nM, 3 h after ingestion were less than 7% of the peak serum concentration (950 nM at 4 h, indicating minimal secretion. Although omeprazole is a potentially useful therapy for refractory gastroesophageal reflux during pregnancy and lactation, further data are needed to define better its safety and efficacy.

    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.

    Full Text Available Vesicoureteral reflux (VUR is a common congenital renal tract anomaly in children. Reports from Sudan are scanty. We report the characteristics, presentation and outcome of primary VUR in a tertiary care hospital. The records of 30 patients (16 males; 53% followed-up between January 2004 and December 2010 were reviewed. The mean age at the time of diagnosis was 4 ± 3.9 years and 47% were <2 years of age. Renal ultrasound scan (USS failed to predict VUR in 17% of the patients. On voiding cysturethrogram (VCUG, VUR was bilateral in 57% and severe grade in 64%. Grades were not significantly associated with age, gender or site of VUR. Initial dimercaptosuccinic acid radionuclide scan showed renal damage in 61.5% of the patients. Renal damage was significantly associated with female gender and severe VUR, but not with age of onset or history of urinary tract infection (UTI. Thirteen patients (43.3% presented with acute UTI, eight (26.6% with non-specific urinary tract symptoms and nine (30% with persistently elevated serum creatinine. Urine cultures were positive in 73% of patients, and E. coli was the most common pathogen. Renal impairment at presentation was significantly associated with bilateral severe VUR and history of UTI but not age or gender. After a mean follow-up period of 1.78 years (6 months to 5 years, 70% of patients remained with normal renal function and 30% progressed to chronic kidney disease; two of them died. In conclusion, our data is different from many studies. Features of primary VUR in Sudanese children are late age of onset, equal gender affection and predominance of severe grade. Presentation is associated with a high rate of UTI, renal damage and advanced renal impairment. Measures to improve early detection and treatment of VUR may reduce the risk of kidney damage.

Randomized controlled study. Suez Canal University Hospital, Ismalia, Egypt. A total of 212 patients with symptoms of LPRD. Patients were evaluated by laryngoscopy, ambulatory pH monitoring for 24 hours, and HPSA testing. Esomeprazole magnesium as a monotherapy was evaluated vs triple therapy in patients with HP infection. To determine the incidence of HPSA in patients with LPRD, and to make a comparison of 2 treatment regimens that have been used based on the presence or absence of HPSA positivity in patients with LPRD. Persistent dry cough and a feeling of a lump in the throat (globus sensation) were the most frequent symptoms of LPRD, while posterior laryngeal inflammation was the main laryngoscopic finding. Results from the HPSA test were positive in 57% of the studied group. Patients with negative HPSA were treated with esomeprazole as single modality with a reported improvement score of 96.6%. Patients with positive HPSA test results were divided into 2 groups: 1 received only esomeprazole, with reported improvement in 40%, whereas the second group was treated with esomeprazole, plus amoxicillin sodium and clarithromycin (triple therapy) and reported a 90% incidence of symptom improvement. The incidence of HP infection in patients with LPRD in our study was 57%. Triple therapy showed a higher cure rate in patients with HPSA-positive test results.

    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 reflux symptoms and GERD-HRQL were significantly improved in both groups (P gastroesophageal junction pressure (GEJP) significantly increased in the DBT + rabeprazole group (P reflux barrier, providing a non-pharmacological maintenance therapy and reducing medical costs for patients with GERD. © 2015 International Society for Diseases of the Esophagus.

    - Gastroesophageal reflux disease is the most common esophageal disorder in pediatrics. - The aim of this study was to compare reflux parameters of typical and atypical symptoms of gastroesophageal reflux disease using 24-hour esophageal pH monitoring and multichannel intraluminal impedance in pediatric population. - In this prospective study, 43 patients aged less than 18 year with suspected gastroesophageal reflux disease were enrolled. The patients were divided into two groups based on the main presenting symptoms (typical versus atypical). Twenty four-hour pH monitoring and multichannel intraluminal impedance were performed in all the patients for comparing these two group regarding association of symptoms and reflux. Number of refluxes, pH related reflux, total reflux time, reflux more than 5 minutes, longest time of the reflux, lowest pH at reflux, reflux index were recorded and compared. Data comparison was done using SPSS. - The mean age of the patients was 5.7±3.4 years and 65.1% were male. Out of 43 patients 24 cases had typical symptoms and 19 had atypical symptoms. The mean reflux events detected by multichannel intraluminal impedance was more than mean reflux events detected by pH monitoring (308.4±115.8 vs 69.7±66.6) with P value of 0.037, which is statistically significant. The mean symptom index and symptom association probability were 35.01% ± 20.78% and 86.42% ± 25.79%, respectively in multichannel intraluminal impedance versus 12.73% ± 12.48% and 45.16% ± 42.29% in pH monitoring (P value reflux was 46.26±47.16 and 30.9±22.09 for atypical and typical symptoms respectively. The mean symptom index was 18.12% ± 13.101% and 8.30% ± 10.301% in atypical and typical symptoms respectively (P=0.034). Bolus clearance was longer in atypical symptoms compared typical symptoms(Preflux was found in children with atypical symptoms of reflux. Longer duration of bolus clearance was found in group with atypical symptoms of reflux.

    Proton pump inhibitors and histamine H2 receptor antagonists are two of the most commonly prescribed drug classes for pediatric gastroesophageal reflux disease, but their efficacy is controversial. Many patients are treated with these drugs for atypical manifestations attributed to gastroesophageal reflux, even that causal relation is not proven. To evaluate the use of proton pump inhibitors and histamine H2 receptor antagonists in pediatric gastroesophageal reflux disease through a systematic review. A systematic review was performed, using MEDLINE, EMBASE and Cochrane Central Register of Controlled Trials databases. The search was limited to studies published in English, Portuguese or Spanish. There was no limitation regarding date of publication. Studies were considered eligible if they were randomized-controlled trials, evaluating proton pump inhibitors and/or histamine H2 receptor antagonists for the treatment of pediatric gastroesophageal reflux disease. Studies published only as abstracts, studies evaluating only non-clinical outcomes and studies exclusively comparing different doses of the same drug were excluded. Data extraction was performed by independent investigators. The study protocol was registered at PROSPERO platform (CRD42016040156). After analyzing 735 retrieved references, 23 studies (1598 randomized patients) were included in the systematic review. Eight studies demonstrated that both proton pump inhibitors and histamine H2 receptor antagonists were effective against typical manifestations of gastroesophageal reflux disease, and that there was no evidence of benefit in combining the latter to the former or in routinely prescribing long-term maintenance treatments. Three studies evaluated the effect of treatments on children with asthma, and neither proton pump inhibitors nor histamine H2 receptor antagonists proved to be significantly better than placebo. One study compared different combinations of omeprazole, bethanechol and placebo for the

    Gastroesophageal reflux disease (GERD) is a highly prevalent gastrointestinal disorder. Proton pump inhibitors have profoundly revolutionized the treatment of GERD. However, several areas of unmet need persist despite marked improvements in the therapeutic management of GERD. These include the advanced grades of erosive esophagitis, nonerosive reflux disease, maintenance treatment of erosive esophagitis, refractory GERD, postprandial heartburn, atypical and extraesophageal manifestations of GERD, Barrett’s esophagus, chronic protein pump inhibitor treatment, and post-bariatric surgery GERD. Consequently, any future development of novel therapeutic modalities for GERD (medical, endoscopic, or surgical), would likely focus on the aforementioned areas of unmet need. PMID:26130628

    Full Text Available This paper describes a shortcut procedure for batch distillation simulation with a variable reflux policy. The procedure starts from a shortcut method developed by Sundaram and Evans in 1993 and uses an iterative cycle to calculate the reflux ratio at each moment. The functional relationship between the concentrations at the bottom and the dome is evaluated using the Fenske equation and is complemented with the equations proposed by Underwood and Gilliland. The results of this procedure are consistent with those obtained using a fast method widely validated in the relevant literature.

    Gastroesophageal reflux disease (GERD), which is common in many communities, is associated with structural factors, eating habits, and the use of certain drugs. The use of such drugs can lead to the emergence of GERD and can also exacerbate existing reflux symptoms. These drugs can contribute to GERD by directly causing mucosal damage, by reducing lower esophageal sphincter pressure (LESP), or by affecting esophagogastric motility. In this article, we report our investigation of the relationships between GERD and medications within the scope of the "Turkish GERD Consensus Group." For the medication groups for which sufficient data were obtained (Figure 1), a systematic literature review in English was conducted using the keywords "gastroesophageal reflux" [MeSH Terms] and "anti-inflammatory agents, non-steroidal" [MeSH Terms], "gastroesophageal reflux" [MeSH Terms] and "acetylsalicylic acid" [MeSH Terms], "gastroesophageal reflux" [All Fields] and "estrogenic agents" [All Fields], "gastroesophageal reflux" [All Fields] and "progesterones" [All Fields], "gastroesophageal reflux" [All Fields] and "hormone replacement therapy" [All Fields], "gastroesophageal reflux" [MeSH Terms] and "diphosphonates" [MeSH Terms] OR "diphosphonates" [All Fields], "calcium channel blockers" [MeSH Terms] and "gastroesophageal reflux" [MeSH Terms], "gastroesophageal reflux" [MeSH Terms] and "nitrates" [MeSH Terms], "gastroesophageal reflux" [MeSH Terms] and "antidepressive agents" [MeSH Terms], "gastroesophageal reflux" [MeSH Terms] and "benzodiazepines" [MeSH Terms] and "hypnotic drugs" [MeSH Terms], "gastroesophageal reflux" [MeSH Terms] and "cholinergic antagonists" [MeSH Terms], "gastroesophageal reflux" [MeSH Terms] and "theophylline" [MeSH Terms], and "gastroesophageal reflux [MeSH Terms] AND "anti-asthmatic agents" [MeSH Terms].

    Full Text Available Aim: We retrospectively reviewed videourodynamic outcomes in children with primary vesicoureteral reflux. The aim of this study to evaluate the relationship between vesicoureteral reflux grade and bladder compliance. Material and Method: Videourodynamic traces of 53 children with primary vesicoureteral reflux investigated between January 2004 and January 2012 were reviewed. The detrusor pressures of the point when the reflux started were recorded. The detrusor pressures 10 cmH2O or less at that point was accepted as normal compliance (Group 1, the detrusor pressures more than10 cm H2O was accepted as hipocompliance (Group 2. The reflux grades were divided into two grades, low-grade reflux (grades 1 and 2, high-grade reflux (grades 3, 4 and 5. Data were analyzed using the chi-square test. Results: Patients’ ages ranged between 5 and 11 years (mean 7.09±1.81 years. Of the 53 patients, 29 (54.7% had normal compliance (Group 1, 24 (45.3% had hipocompliance (Group 2.

In group 2, 8 (33.3% patients had a low-grade reflux, 16 (66.7% patients had a high-grade reflux. The detected high-grade reflux in-group 2 was significantly higher than in-group 1 (p<0.001. Discussion: The physicians should be considering the bladder compliance at the point when the reflux started in primary vesicoureteral reflux cases. The bladder hipocompliance may play a secondary role in reflux grade.

    There is a known association between nonneurogenic lower urinary tract conditions and vesicoureteral reflux. Whether reflux is secondary to the lower urinary tract condition or coincidental is controversial. We determined the rate of reflux resolution in patients with lower urinary tract dysfunction using targeted treatment for the underlying condition. Patients diagnosed and treated for a lower urinary tract condition who had concomitant vesicoureteral reflux at or near the time of diagnosis were included. Patients underwent targeted treatment and antibiotic prophylaxis, and reflux was monitored with voiding cystourethrography or videourodynamics. Vesicoureteral reflux was identified in 58 ureters in 36 females and 5 males with a mean age of 6.2 years. After a mean of 3.1 years of treatment reflux resolved with targeted treatment in 26 of 58 ureters (45%). All of these patients had a history of urinary tract infections before starting targeted treatment. Resolution rates of vesicoureteral reflux were similar for all reflux grades. Resolution or significant improvement of reflux was greater in the ureters of patients with dysfunctional voiding (70%) compared to those with idiopathic detrusor overactivity disorder (38%) or detrusor underutilization (40%). Vesicoureteral reflux associated with lower urinary tract conditions resolved with targeted treatment and antibiotic prophylaxis in 45% of ureters. Unlike the resolution rates reported in patients with reflux without a coexisting lower urinary tract condition, we found that there were no differences in resolution rates among grades I to V reflux in patients with lower urinary tract conditions. Patients with dysfunctional voiding had the most improvement and greatest resolution of reflux. Additionally grade V reflux resolved in some patients.

    To date, most concepts on the frequency of gastro-oesophageal reflux episodes and the efficiency of the antireflux barrier have been based on inferences derived from measurement of oesophageal pH. The development of intraluminal impedance monitoring has highlighted the fact that pH monitoring does not detect all gastro-oesophageal reflux events when little or no acid is present in the refluxate, even if special pH tracing analysis criteria are used. In November 2002, a workshop took place at which 11 specialists in the field of gastro-oesophageal reflux disease discussed and criticised all currently available techniques for measurement of reflux. Here, a summary of their conclusions and recommendations of how to achieve the best results from the various techniques now available for reflux measurement is presented. PMID:15194656

    Since the development of ambulatory esophageal pH monitoring test to diagnose gastroesophageal reflux disease (GERD), several parameters have been introduced. The aim of this study was to assess whether using the symptom index (SI), symptom sensitivity index (SSI), and symptom association probability (SAP), in addition to the DeMeester score (DS), would be useful for interpreting the Bravo pH monitoring test. A retrospective study, which included 68 patients with reflux symptoms refractory to proton pump inhibitor (PPI) therapy who underwent a Bravo capsule pH test between October 2006 and May 2015, was carried out. Acid reflux parameters and symptom reflux association parameters were analyzed. The median percent time of total pHvariation in percent time of total pHpH test, diagnosis of GERD, including reflux hypersensitivity, can be improved by performing an analysis of the symptom-reflux association and of the day-to-day variation.

    We present demographic differences across the gastro-oesophageal reflux disease (GORD) spectrum in a UK District General Hospital. Data were prospectively collected over 37 years. At endoscopy patients were categorized as: erosive oesophagitis (EO), Barrett's oesophagus (BO) or nonerosive reflux disease (NER). Analysis 1: comparison of EO, BO and NER 1977-2001 when the database for GORD without BO closed. Analysis 2: demographic differences in oesophageal adenocarcinoma (OAC) in total BO population diagnosed 1977-2011. GORD 1977-2001 (n=11 944): sex, male predominance in EO and BO but not NER; male : female ratios, 1.81, 1.65, 0.87, respectively (P<0.0001); mean age at presentation, EO 54 years, BO 62 years, NER 50 years; women were older than men by 10, 7 and 6 years, respectively.BO 1977-2011: prevalent OAC, 87/1468 (6%); male : female ratio, 4.1 (P<0.0001); incident OAC, 54/1381 (3.9%); male : female ratio, 3.5 (P<0.0001). Among all BO, more men developed OAC (3 vs. 0.9%). Within each sex, proportion of OAC higher among men (4.9 vs. 2.3%); at OAC diagnosis women were slightly but not significantly older (69.9 vs. 72.3 years, P=0.322). Two views may explain our findings. First, women have either milder reflux, or reduced mucosal sensitivity hence reflux remains silent for longer. Alternatively, women genuinely develop reflux later, that is, are more protected and for longer from developing GORD and its complications. Early evidence is emerging that female sex hormones may indeed have a protective role in GORD during the reproductive period. We suggest reflux and its consequences may be an example of 'protection' conferred on Eve.

    In a follow-up after fundoplication, 61 patients underwent a double contrast examination of the stomach and a radiologic examination to detect any gastro-oesophageal reflux. The radiologic findings were compared with pH reflux test and symptoms. Gastro-oesophageal reflux was found in 7 patients at radiologic examination. None of these patients had an adequate fundoplication at a double contrast examination of the stomach and all had symptoms indicating reflux. Recurrence of gastro-oesophageal reflux may be shown at the radiologic examination and predicted by the morphologic appearances at the double contrast examination. (orig.)

    The influence of Cisapride on food-stimulated gastro-oesophageal reflux meachanisms was studied in a double-blind cross-over investigation in 24 consecutive patients selected by endoscopy, 12 with microscopical evidence of gastro-oesophageal reflux and 12 with additional macroscopic oesoghagitis. 63% had food-stimulated gastro-oesophageal reflux, and Cisapride significantly reduced the tendency to gastro-oesophageal reflux and mucosal contact time between gastric content and the oesophageal mucosa in 73% of these patients. It is concluded that Cisapride could be valuable in the treatment of gastro-oesophageal reflux. (orig.) [de

    Increased salivary pepsin could indicate an increase in gastro-esophageal reflux, however, previous studies failed to demonstrate a correlation between salivary pepsin concentrations and 24-hour esophageal acid exposure. This study aims to detect the salivary pepsin and to evaluate the relationship between salivary pepsin concentrations and intercellular spaces (IS) in different gastroesophageal reflux disease phenotypes in patients. A total of 45 patients and 11 healthy volunteers were included in this study. All subjects underwent upper gastrointestinal endoscopy, 24-hour ambulatory multichannel impedance-pH (MII-pH) monitoring, and salivary sampling at 3-time points during the 24-hour MII-pH monitoring. IS were measured by transmission electron microscopy, and salivary pepsin concentrations were determined by enzyme-linked immunosorbent assay. The IS measurements were greater in the esophagitis (EE), non-erosive reflux disease (NERD), and hypersensitive esophagus (HO) groups than in the functional heartburn (FH) and healthy volunteer groups, and significant differences were indicated. Patients with NERD and HO had higher average pepsin concentrations compared with FH patients. A weak correlation was determined between IS and salivary pepsin among patients with NERD ( r = 0.669, P = 0.035). We confirmed the presence of a higher level of salivary pepsin in patients with NERD than in patients with FH. Salivary pepsin concentrations correlated with severity of mucosal integrity impairment in the NERD group. We suggest that in patients with NERD, low levels of salivary pepsin can help identify patients with FH, in addition the higher the pepsin concentration, the more likely the severity of dilated IS.

    Full Text Available Hyperinsulinemia could have a role in the growing incidence of esophageal adenocarcinoma (EAC and its pre-cancerous lesion, Barrett’s Esophagus, a possible consequence of Gastro-Esophageal Reflux Disease. Obesity is known to mediate esophageal carcinogenesis through different mechanisms including insulin-resistance leading to hyperinsulinemia, which may mediate cancer progression via the insulin/insulin-like growth factor axis. We used the hyperinsulinemic non-obese FVB/N (Friend leukemia virus B strain MKR (muscle (M-IGF1R-lysine (K-arginine (R mouse model to evaluate the exclusive role of hyperinsulinemia in the pathogenesis of EAC related to duodeno-esophageal reflux. FVB/N wild-type (WT and MKR mice underwent jejunum-esophageal anastomosis side—to end with the exclusion of the stomach. Thirty weeks after surgery, the esophagus was processed for histological, immunological and insulin/Insulin-like growth factor 1 (IGF1 signal transduction analyses. Most of the WT mice (63.1% developed dysplasia, whereas most of the MKR mice (74.3% developed squamous cell and adenosquamous carcinomas, both expressing Human Epidermal growth factor receptor 2 (HER2. Hyperinsulinemia significantly increased esophageal cancer incidence in the presence of duodenal-reflux. Insulin receptor (IR and IGF1 receptor (IGF1R were overexpressed in the hyperinsulinemic condition. IGF1R, through ERK1/2 mitogenic pattern activation, seems to be involved in cancer onset. Hyperinsulinemia-induced IGF1R and HER2 up-regulation could also increase the possibility of forming of IGF1R/HER2 heterodimers to support cell growth/proliferation/progression in esophageal carcinogenesis.

    2015-01-01

    COPD is a long-term condition associated with considerable disability with a clinical course characterized by episodes of worsening respiratory signs and symptoms associated with exacerbations. Gastroesophageal reflux disease (GERD) is one of the most common gastrointestinal conditions in the general population and has emerged as a comorbidity of COPD. GERD may be diagnosed by both symptomatic approaches (including both typical and atypical symptoms) and objective measurements. Based on a mix of diagnostic approaches, the prevalence of GERD in COPD ranges from 17% to 78%. Although GERD is usually confined to the lower esophagus in some individuals, it may be associated with pulmonary microaspiration of gastric contents. Possible mechanisms that may contribute to GERD in COPD originate from gastroesophageal dysfunction, including altered pressure in the lower esophageal sphincter (which normally protect against GERD) and changes in esophageal motility. Proposed respiratory contributions to the development of GERD include respiratory medications that may alter esophageal sphincter tone and changes in respiratory mechanics, with increased lung hyperinflation compromising the antireflux barrier. Although the specific cause and effect relationship between GERD and COPD has not been fully elucidated, GERD may influence lung disease severity and has been identified as a significant predictor of acute exacerbations of COPD. Further clinical effects could include a poorer health-related quality of life and an increased cost in health care, although these factors require further clarification. There are both medical and surgical options available for the treatment of GERD in COPD and while extensive studies in this population have not been undertaken, this comorbidity may be amenable to treatment.

    Full Text Available Introduction: Gastroesophageal reflux is a common gastrointestinal disorder among infants, which can cause complications, such as esophagitis and Barrett's esophagus if its diagnosis and treatment are delayed. On the other hand, similarity of Gastro esophageal Reflux symptoms with symptoms of other childhood diseases makes its diagnosis and treatment difficult. So a proper tool for early screening and diagnostic test is essential. Methods: This study was conducted on 221 infants(2 to 12 months with initial symptoms of gastro esophageal reflux(frequent vomiting, restlessness after feeding, no weight gain, coughing repeatedly and refusing to eat that referred to pediatric Clinic of Rajai Hospital in Tonekabon. Data was collected with demographic and infant gastro esophageal reflux questionnaire by use of the information in records and interview with parents. Then the samples were examined via sonography for gastroesophagial reflux. Results: After initial screening based on infants gastro esophageal reflux tool, gastro esophageal reflux by ultrasound was positive in 63/3% of infants. The mean esophageal diameter was (20/73±2/54mm in infants with gastro esophageal reflux and (23/71±2/35mm in infants without gastro esophageal reflux. Conclusion: Due to the similarity of gastro esophageal Reflux symptoms with clinical symptoms of other childhood diseases, use of an initial screening measurement for early assessment of gastro esophageal reflux in infants is necessary. Moreover, appropriate, available and low costs diagnostic method with little complication seems essential such as ultrasonography for confirm diagnosis and early treatment.

    The study and clinical assessment of enterogastric bile reflux has been restricted for want of a simple non-invasive test for its detection and quantification. This paper describes such a test in which biliary excretion scintigraphy has been combined with a milk meal provocation. Two of 10 healthy volunteers studied showed probable reflux of approximately 5 per cent of total initial abdominal field activity. Among 73 patients studied, 37 patients showed definite reflux of up to 47 per cent. Reflux occurred in 19 of 22 post-gastric surgery patients and in 7 of 22 patients with peptic ulcer disease, gastritis or gastro-oesophageal reflux. None of 7 patients with 'non-specific' abdominal pain showed any reflux, but 11 of 22 patients with gallstone disease or previous cholecystectomy showed reflux of up to 35 per cent, including 9 of 11 patients with loss of gallbladder reservoir function.

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

    Gastroesophageal reflux disease affects more than 10% of the adult population. Most patients can be effectively treated with lifestyle changes and adequate acid-reducing therapy. However, about 10% of the patients remain symptomatic despite treatment and severe complications may develop. Interestingly, some of these complications seem to be a sort of defensive mechanism that may either alleviate the patient's symptoms or prevent developing further complications. In Barrett's esophagus, which can be unambigously considered as a complication of gastroesophageal reflux disease, reflux symptoms ruining the quality of life may significantly improve, since the metaplastic Barrett epithelium is much more resistent to gastric acid, than the normal epithelial lining of the esophagus. Furthermore, the motility disorders (hypertensive lower esophageal sphincter, achalasia, cricopharyngeal achalasia) and structural changes (Schatzki's ring, esophageal stricture, subglottic trachea stenosis), which develop as a complication of reflux may help to prevent aspiration that can cause new complaints and may lead to further complications.

    Asthma and gastroesophageal reflux (GORD) are widespread and potentially coexisting diseases. Incidence and prevalence of concomitant asthma and GORD are highly variable among studies. This is mainly due to the heterogeneity of study designs. To explain a potential link, some pathophysiological anomaly has been proposed such as the altered pressure gradient between thorax and abdomen, the parasympathetic reflex, the heightened bronchial reactivity and chemical effects of microaspired gastric juice. An accurate diagnosis of asthma and GORD is pivotal in order to lead effective treatment and to reach a significant positive outcome, in terms of quality of life and respiratory function amelioration. Gastroenterological evaluation of GORD includes the empiric proton pump-inhibitors (PPIs) trial, the esophageal pH monitoring and endoscopic evaluation. Besides spirometric investigations, pulmonologist have more specific examens such as bronchoalveolar lavage and exhaled breath condensate. Actually, international recommendations regarding the management of asthma suggest the assessment of potential comorbidities, including the presence of GORD, mostly in children, only in patients with normal pulmonary functional tests with frequent respiratory symptoms, and in case of uncontrolled asthma. Symptomatic gastro-esophageal reflux patients should be treated, but those with uncontrolled asthma should not be treated with anti-reflux drugs unless they are symptomatic for reflux. This review explores the state of the art about the pathogenesis and the management of the relationship between asthma and GORD.

    Ambulatory 24-hour double-probe pH monitoring seems to be the best test to measure reflux. Artifacts caused by intake of acid foods and beverages have to be excluded, necessitating a time-consuming manual review of the 24-hour data. Dietary restrictions used to bypass these artifacts would interfere

    Radionuclide hepatobiliary imaging was performed on a patient with a longstanding history of scleroderma who presented with abdominal pain suggestive of biliary disease. Cystic duct patency was documented after 10 min with tracer accumulation in the second portion of the duodenum which failed to progress consistent with the duodenal hypomotility of scleroderma. The patient was given intravenous Kinevac resulting in gastroesophageal reflux of radionuclide.

    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 reflux disease (n = 378) and NERD (n = 293). NERD was also a predictive factor for frequent belching during EGD (odds ratio = 6.61, P Diseases of the Esophagus.

    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. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available Background Gastroesophageal reflux disease (GERD is very common in developed world, with the prevalence of disease is between 6 and 20%. Pathologic reflux can provoke not only typical symptoms (heartburn and regurgitation but also atypical symptoms and diseases of extraoesophageal organs (pulmonary, ENT, mouth. High prevalence of GERD in patients with unexplained chest pain, asthma, chronic cough, chronic laryngitis, hoarsness and dental erosions is not a proof of causality. GERD can cause these diseases with reflux of acid and pepsin into pharynx, larynx, lungs and mouth (reflux theory or through vasovagal mechanisms (reflex theory. Conclusions Good therapeutic success with medical or operative treatment in early methodologically not well conducted studies has not been completely proven in double-blind placebo controlled studies. GERD is an ethyological reason for these extraoesophageal symptoms and diseases in an approximately one third of patients. With diagnostic modalities that we have now, we cannot clearly define in which patient is GERD is an ethyologic factor or a contributer, before we start the treatment. In patients suspected of having GERD, there is therapeutic option of a trial with high dose of proton pump inhibitor for 3 to 6 months. In other patients with low clinical suspicion of GERD, 24-hour pH testing should be done first.

    We aimed to evaluate a possible relation between gastroesophageal reflux disease and middle ear effusion in children. Children who came to ear, nose, and throat (ENT) department with the symptoms of hearing loss or aural fullness and diagnosed as OME by examination and tympanometry were included into the study. Children were reviewed gastroesophageal reflux disease symptoms including the following: (a) airway symptoms: stridor, frequent cough, recurrent croup, wheezing, nasal congestion, obstructive apnea, hoarseness, and throat clearing; (b) feeding symptoms: frequent emesis, dysphagia, choking: gagging, sore throat, halitosis, food refusal, regurgitation, pyrosis, irritability, failure to thrive, and anemia. Diagnosis is made with at least one positive test of radionuclide gastroesophageal scintigraphy or 24 h pH probe in the patients with reflux. ENT findings were also examined between gastroesophageal reflux disease positive and gastroesophageal reflux disease negative groups. Approximately 39 (54.9%) of 71 children had at least 1 positive test for gastroesophageal reflux disease. Between the gastroesophageal reflux disease-positive and gastroesophageal reflux disease-negative groups, symptoms of reflux were not significantly different. Two pooled variables were created: airway complex (stridor, frequent cough, throat clearing), and feeding complex (irritability, pyrosis, failure to thrive). Percentage of positive symptom complexes were no statistically different between gastroesophageal reflux disease-positive and gastroesophageal reflux disease-negative groups (>0.05). Ear, nose, and throat disorders (including rhinitis/sinusitis, adenoid hypertrophy, tonsillitis/pharyngitis, and laryngitis) were more frequent in gastroesophageal reflux disease-positive group. Tonsillitis/pharyngitis was significantly different between the gastroesophageal reflux disease positive and gastroesophageal reflux disease-negative groups. Upper respiratory tract infections were seen

    Full text: The aim of this study is: to identify any possible relationship between recurrent lower respiratory tract infection and GER, to identify any possible relationship between asthma and GER, to determine the prevalence of GER in children suffering from RLRTI and bronchial asthma, and to evaluate the sensitivity and accuracy of different GER diagnostic modalities. Thirty children with recurrent lower respiratory tract infection and bronchial asthma were evaluated for possible presence of the GER. Radionuclide gastroesophageal scintigraphy was performed in all these 30 patients (age range 6 months - 10 years). Patients also underwent ultrasonography and/or barium swallow or fluoroscopy on separate day. Patients were grouped according to presenting coinplaints and investigative modalities. Group A was the patients of RLRTI, which underwent GER scintigraphy, barium studies and ultrasonography. Group B patients were patients with bronchial asthma who underwent all 3 investigations. Group C was patients with RLRTI who under went GER scintigraphy and barium studies only. Patients with bronchial asthma who underwent barium studies and GER scintigraphy were included in group D. Group E and F were patients with RLRTI and bronchial asthma who underwent ultrasonography and GER scintigraphy only respectively. For each group, reflux index was calculated in all positive patients. GER reflux of varying degrees was observed in 20 % patients. The severity of the clinical symptoms was directly proportional to the severity of gastroesophageal reflux. Reflux index was positively correlating with clinical symptoms as well. When compared with other investigative modalities employed GER scintigraphy was found to be more superior in terms of sensitivity and specificity. Objective assessment of gastroesophageal reflux with the help of GER scintigraphy is feasible and is superior to other modalities and it should be employed much more frequently as an initial investigative procedure

    Gastro-esophageal reflux disease is a troublesome disease for many patients, severely affecting their quality of life. Choice of treatment depends on a combination of patient characteristics and preferences, esophageal motility and damage of reflux, symptom severity and symptom correlation to acid reflux and physician preferences. Success of treatment depends on tailoring treatment modalities to the individual patient and adequate selection of treatment choice. PubMed, Embase, The Cochrane Database of Systematic Reviews, and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) were searched for systematic reviews with an abstract, publication date within the last five years, in humans only, on key terms (laparosc* OR laparoscopy*) AND (fundoplication OR reflux* OR GORD OR GERD OR nissen OR toupet) NOT (achal* OR pediat*). Last search was performed on July 23nd and in total 54 articles were evaluated as relevant from this search. The laparoscopic Toupet fundoplication is the therapy of choice for normal-weight GERD patients qualifying for laparoscopic surgery. No better pharmaceutical, endoluminal or surgical alternatives are present to date. No firm conclusion can be stated on its cost-effectiveness. Results have to be awaited comparing the laparoscopic 180-degree anterior fundoplication with the Toupet fundoplication to be a possible better surgical alternative. Division of the short gastric vessels is not to be recommended, nor is the use of a bougie or a mesh in the vast majority of GERD patients undergoing surgery. The use of a robot is not recommended. Anti-reflux surgery is to be considered expert surgery, but there is no clear consensus what is to be called an 'expert surgeon'. As for setting, ambulatory settings seem promising although high-level evidence is lacking. Copyright © 2013 Elsevier Ltd. All rights reserved.

    The aims of this observational study were (i) to examine the prevalence of symptomatic and clinically silent proximal and distal gastro-oesophageal reflux (GOR) in adults with chronic obstructive pulmonary disease (COPD) or bronchiectasis, (ii) the presence of gastric aspiration, and (iii) to explore the possible clinical significance of this comorbidity in these conditions. Twenty-seven participants with COPD, 27 with bronchiectasis and 17 control subjects completed reflux symptom evaluation and dual-channel 24 h oesophageal pH monitoring. In those with lung disease, pepsin levels in sputum samples were measured using enzyme-linked immunosorbent assay, with disease severity (lung function and high-resolution computed tomography) also measured. The prevalence of GOR in COPD was 37%, in bronchiectasis was 40% and in control subjects was 18% (P = 0.005). Of those diagnosed with GOR, clinically silent reflux was detected in 20% of participants with COPD and 42% with bronchiectasis. While pepsin was found in 33% of COPD and 26% of bronchiectasis participants, the presence of pepsin in sputum was not related to a diagnosis of GOR based on oesophageal pH monitoring in either condition. Neither a diagnosis of GOR nor the presence of pepsin was associated with increased severity of lung disease in COPD or bronchiectasis. The prevalence of GOR in COPD or bronchiectasis is twice that of the control population, and the diagnosis could not be based on symptoms alone. Pepsin was detected in sputum in COPD and bronchiectasis, suggesting a possible role of pulmonary aspiration, which requires further exploration. © 2013 The Authors.

    Exposure to excess gastric acid resulting from gastroesophageal reflux disease, also known as acid reflux or heartburn, might contribute to initiation of head and neck squamous cell carcinoma, particularly laryngeal cancer. Prior epidemiologic studies have reported inconsistent results. We sought to clarify this relationship using an observational study with a larger available sample size and better-characterized exposure information than most prior studies. A population-based case-control study of head and neck cancer in North Carolina with 1,340 newly diagnosed cases and 1,378 controls matched on age, race, and sex. We used unconditional logistic regression to examine associations between self-reported heartburn and development of overall head and neck cancer as well as development of cancer at specific tumor sites. Subgroup analysis by smoking and alcoholic drinking status was used to make comparisons with a previous study that used a similar study design. Overall, an increased odds of head and neck cancer was not associated with either self-reported history of heartburn symptoms (odds ratio = 0.85; 95% confidence interval 0.68, 1.06) or self-reported medical diagnosis of GERD (OR = 0.89; 95% CI 0.71, 1.11). These patterns held for specific tumor sites. For laryngopharyngeal cancer, we did not detect any associations regardless of joint smoking and alcoholic drinking status. Gastroesophageal reflux does not appear to play a role in development of head and neck cancer. 3b.

    Full Text Available Purpose: to develop criteria for the selection of optimal tactics of supporting treatment of nonerosive gastroesophageal reflux disease with proton pump inhibitors in menopausal women suffering from diabetes mellitus type II. Material and Methods. 186 patients aged 45-59 who suffer from gastroesophageal reflux disease have been followed up, 46 of which suffer from diabetes mellitus type II as well. The climacteric syndrome's morbidity has been assessed in accordance with the modified menopause index; the level of glycated hemoglobin has been measured by the Abbott analyzer produced in the USA. Results. It is established that irrespective of the supporting treatment, the gastroesophageal reflux disease remittance was shorter in direct proportion with increase of the HbA1c level and the value of the modified menopause index in menopausal women suffering from diabetes mellitus type II. Conclusion. When the climacteric syndrome was mild or moderate, taking 20 mg Omeprazole once a day and "on demand" has comparable results, therefore this group of women prefer the "on demand" regimen as it lowers the risk of osteoporosis progression and further bone fracture. Taking 20 mg Omeprazole once a day, every other day, and "on demand" allows the disease remittance to prolong for a year and longer in less than 30% of women suffering from severe climacteric syndrome and having HbA1c>9.0%; however, this number may grow up to 70% of women in case they follow medical advice and reduce their carbohydrate input to 11 carbohydrate units and less.

    Obstructive sleep apnea (OSA) leads to upper respiratory tract obstruction, causing increased abdominal-gastric pressure and decreased lower esophageal sphincter (LES) pressure and thus gastroesophageal reflux (GER). Continuous positive airway pressure (CPAP) is known to be an effective method for OSA treatment, but its effect on GER is still controversial. There are a very few studies investigating CPAP and GER relationship and performed based on pre- and post-treatment objective parameters of GER in patients with OSA. The study investigated the effect of CPAP treatment in patients with moderate and severe OSA without GER complaints on pre- and post-treatment objective GER parameters. The study included 25 patients with respiratory disturbance indices >15 without reflux symptoms who had undergone polysomnography at sleep laboratory. Age, sex, body mass index (BMI), waist, and neck circumference of the patients were documented. DeMeester score, LES pressure, and polysomnography parameters were evaluated pre- and post-CPAP. The results were statistically evaluated, and p value CPAP phase, mean sphincter pressure was 22.2 ± 1.2 (range 8-73), and mean DeMeester score was 18 ± 15.5 (range 0.2-57). At the post-CPAP, mean sphincter pressure was 22.9 ± 1.6 (range 9-95), and mean DeMeester score was 16.3 ± 14.8 (range 0.2-55). No significant difference (p > 0.05) was found comparing pre-CPAP and post-CPAP measurements. Objective criteria show that CPAP treatment does not cause reflux in patients with OSA. Unlike studies reported in the literature, this conclusion has been reached by pre- and post-CPAP assessments.

    Nocturnal gastroesophageal reflux (nGER) is common among patients with obstructive sleep apnea (OSA). Previous studies demonstrated that continuous positive airway pressure (CPAP) reduces symptoms of nGER. However, improvement in nGER symptoms based on objective CPAP compliance has not been documented. We have examined the polysomnographic characteristics of patients with nGER and OSA and looked for association of OSA severity and CPAP compliance with improvement in nGER symptoms. We interviewed 85 veterans with OSA to assess their daytime sleepiness (Epworth Sleepiness scale [ESS]) and nGER symptom frequency after their polysomnography and polysomnographic data were reviewed. At 6 months' follow-up, ESS score, nGER score, and CPAP machine compliance data were reassessed. Data from 6 subjects were dropped from final analysis due to their initiation of new medication for nGER symptom since the initial evaluation. Sixty-two of 79 (78%) patients complained of nGER symptoms during initial visit. At baseline, nGER score was correlated with sleep efficiency (r = 0.43), and BMI correlated with the severity of OSA (r = 0.41). ESS and nGER improved (p CPAP compliant patients. A minimum CPAP compliance of 25% was needed to achieve any benefit in nGER improvement. Nocturnal gastroesophageal reflux is common among patients with OSA which increases sleep disruption and worsens the symptoms of daytime sleepiness. CPAP therapy may help improve the symptoms of both nocturnal acid reflux and daytime sleepiness, but adherence to CPAP is crucial to achieve this benefit. © 2016 American Academy of Sleep Medicine.

    Acid reflux episodes that extend to the proximal esophagus are more likely to be perceived. This suggests that the proximal esophagus is more sensitive to acid than the distal esophagus, which could be caused by impaired mucosal integrity in the proximal esophagus. Our aim was to explore sensitivity to acid and mucosal integrity in different segments of the esophagus. We used a prospective observational study, including 12 patients with gastroesophageal reflux disease (GERD). After stopping acid secretion-inhibiting medication, two procedures were performed: an acid perfusion test and an upper endoscopy with electrical tissue impedance spectroscopy and esophageal biopsies. Proximal and distal sensitivity to acid and tissue impedance were measured in vivo, and mucosal permeability and epithelial intercellular spaces at different esophageal levels were measured in vitro. Mean lag time to heartburn perception was much shorter after proximal acid perfusion (0.8 min) than after distal acid perfusion (3.9 min) (P = 0.02). Median in vivo tissue impedance was significantly lower in the distal esophagus (4,563 Ω·m) compared with the proximal esophagus (8,170 Ω·m) (P = 0.002). Transepithelial permeability, as measured by the median fluorescein flux was significantly higher in the distal (2,051 nmol·cm(-2)·h(-1)) than in the proximal segment (368 nmol·cm(-2)·h(-1)) (P = 0.033). Intercellular space ratio and maximum heartburn intensity were not significantly different between the proximal and distal esophagus. In GERD patients off acid secretion-inhibiting medication, acid exposure in the proximal segment of the esophagus provokes symptoms earlier than acid exposure in the distal esophagus, whereas mucosal integrity is impaired more in the distal esophagus. These findings indicate that the enhanced sensitivity to proximal reflux episodes is not explained by increased mucosal permeability. Copyright © 2016 the American Physiological Society.

    Gastroesophageal reflux disease (GERD) is a common disorder of the upper gastrointestinal tract which is typically characterized by heartburn and acid regurgitation. These symptoms are widespread in the community and range from 2.5% to more than 25%. Economic analyses showed an increase in direct and indirect costs related to the diagnosis, treatment and surveillance of GERD and its complications. The aim of this review is to provide current information regarding the natural history of GERD, taking into account the evolution of its definition and the worldwide gradual change of its epidemiology. Present knowledge shows that there are two main forms of GERD, that is erosive reflux disease (ERD) and non-erosive reflux disease (NERD) and the latter comprises the majority of patients (up to 70%). The major complication of GERD is the development of Barrett esophagus, which is considered as a pre-cancerous lesion. Although data from medical literature on the natural history of this disease are limited and mainly retrospective, they seem to indicate that both NERD and mild esophagitis tend to remain as such with time and the progression from NERD to ERD, from mild to severe ERD and from ERD to Barrett's esophagus may occur in a small proportion of patients, ranging from 0 to 30%, 10 to 22% and 1 to 13% of cases, respectively. It is necessary to stress that these data are strongly influenced by the use of powerful antisecretory drugs (PPIs). Further studies are needed to better elucidate this matter and overcome the present limitations represented by the lack of large prospective longitudinal investigations, absence of homogeneous definitions of the various forms of GERD, influence of different treatments, clear exclusion of patients with functional disorders of the esophagus. © 2016 International Society for Diseases of the Esophagus.

    Objective Clinically, patients with proton pomp inhibitor (PPI)-resistant gastro-esophageal reflux disease (GERD) are very challenging to treat. The aim of this study was to determine the rates of symptom relief and adverse events among PPI-resistant GERD patients that changed their therapy from a PPI to vonoprazan. Methods Patients with severe gastroesophageal reflux symptoms (total GERD-Q score ≥8) without endoscopic findings of mucosal breaks who changed their medication from a PPI to vonoprazan during a 12-week period from 2015 to 2016 at 2 hospitals were selected. The primary outcome was the self-reported relief of gastroesophageal reflux symptoms. The odds ratio (OR) for the improvement of symptoms was calculated based on an exact binomial distribution using a matched-pair analysis. The secondary outcome was the GERD-Q score and adverse events. Results Twenty-six patients (6 men) with a mean age of 67.5 years were analyzed. After the therapy was changed from a PPI to vonoprazan, 18 patients (69.2%) reported an improvement, 6 (23.1%) reported no change, and 2 (7.7%) reported an exacerbation of symptoms. A change in therapy was significantly associated with improved self-reported symptoms (OR 9.0, pgastroesophageal reflux symptoms. Vonoprazan is one of the most promising treatment options for patients with PPI-resistant GERD.

    Functional heartburn is defined by Rome III criteria as an endoscopy-negative condition with normal oesophageal acid exposure time, negative symptom association to acid reflux and unsatisfactory response to proton pump inhibitors. These criteria underestimated the role of non-acid reflux. To assess the contribution of impedance-pH with symptom association probability (SAP) analysis in identifying endoscopy-negative patients with reflux disease and separating them from functional heartburn. Consecutive endoscopy-negative patients treated with proton pump inhibitors (n=219) undergoing impedance-pH monitoring off-therapy were analysed. Distal acid exposure time, reflux episodes, SAP and symptomatic response to proton pump inhibitors were measured. Based on impedance-pH/SAP, 67 (31%) patients were pH+/SAP+, 6 (2%) pH+/SAP-, 83 (38%) hypersensitive oesophagus and 63 (29%) functional heartburn. According to pH-metry alone/response to proton pump inhibitors, 62 (28%) were pH+/SAP+, 11 (5%) pH+/SAP-, 61 (28%) hypersensitive oesophagus and 85 (39%) functional heartburn. In the normal-acid exposure population the contribution of impedance-pH/SAP compared to pH-metry alone/response to proton pump inhibitors in identifying patients with reflux disease and functional heartburn resulted to be 10%. In patients with abnormal-acid exposure, the contribution of impedance-pH/SAP increased by 3%. Comparing impedance-pH testing with pH-metry alone plus the response to proton pump inhibitor therapy demonstrated that the latter ones cause underestimation of reflux disease patients and overestimation of functional heartburn patients.

Aims: 1 to determine the relationship between BMI in children and GERD, and 2 to use the National Center for Health Statistics (NCHS values for BMI as a valid source for comparison. Methods: We identified two cohorts of children aged between two and 17 years who were seen at Texas Children’s Hospital (TCH. The first cohort consisted of children diagnosed with GERD based on upper gastrointestinal endoscopic and histologic evaluation, which was recorded in the Pediatric Endoscopic Database System-Clinical Outcomes Research Initiative (PEDS-CORI at TCH. A diagnosis of GERD was based on the presence of erosive esophagitis or esophageal ulcers. Endoscopic reports that were incomplete or did not include demographic features, indications for endoscopy, or endoscopic findings were excluded. The second cohort consisted of all children with symptoms due to gastroesophageal reflux (GER who received outpatient gastrointestinal (GI consultation at TCH for any 9th revision of the International Statistical Classification of Diseases (ICD-9 code suggestive of GER. There was no overlap between the two cohorts as each child was indexed only once. Children with any comorbid illnesses were excluded.Measurements: The records for each child namely, age, gender, height, and weight were obtained on the same date as that of the diagnosis.

    Patients with gastroesophageal reflux disease (GERD) have decreased health-related quality of life (HRQL). The quality of life in patients with laryngopharyngeal reflux (LPR) symptoms is also significantly impaired. However, the impact of LPR symptoms on HRQL in GERD patients has not been studied. A nationwide, random-sample, and face-to-face survey of 300 Korean patients with GERD was conducted from January to March 2013. Gastroesophageal reflux symptoms were assessed using the Rome III questionnaire, LPR symptoms using the reflux symptom index, and HRQL using the EuroQol five dimensions (EQ-5D) questionnaire. A structured questionnaire on patient satisfaction, sickness-related absences, and health-related work productivity was also used. Among the 300 patients with GERD, 150 had LPR symptoms. The mean EQ-5D index was lower in patients with GERD and LPR symptoms than in those without LPR (0.88 vs 0.91, P = 0.002). A linear regression model showed that the severity of LPR symptoms was related to decreased HRQL and was independent of age, marital status, body mass index, or household income. The overall satisfaction rate regarding treatment was lower in patients with GERD and LPR (40.0% vs 69.1%, P = 0.040). GERD patients with LPR symptoms reported greater sickness-related absent hours per week (0.36 vs 0.02 h, P = 0.016) and greater percentages of overall work impairment than those without LPR (31.1% vs 20.8%, P Gastroesophageal reflux disease patients with LPR symptoms have a poorer HRQL, a lower satisfaction rate, and a greater disease burden than those without LPR. © 2017 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

    The association of esophageal motility and gastroesophageal reflux symptoms with respiratory symptoms is not well established in patients with chronic obstructive pulmonary disease (COPD). The aim of this work is to study the abnormalities of esophageal function in COPD patients and study its relation to smoking index, body mass index and indices of hyperinflation. This study included 40 male COPD patients and 10 healthy controls. The patients and controls were subjected to spirometry, body plethysmography, esophageal manometry and 24hr pH-metry. Upper gastrointestinal symptoms were found in 55% of patients, hypotensive upper esophageal sphincter pressure in 65% of patients and hypotensive lower esophageal sphincter pressure in 52.5% of patients. Pathological acid reflux was found in 35% of patients. The severity of GERD increased with increased age, smoking index and body mass index, pesophageal motility disorders in COPD patients, LESP and UESP were significantly negatively correlated to indices of hyperinflation. There was a high prevalence of GERD in COPD patents especially elderly, severe stage of COPD, high smoking index and high body mass index (BMI).

    The main advantage of multichannel intraluminar impedance (MII) compared with pH monitoring is its ability to detect both acid and non-acid gastroesophageal reflux (GER) and to determine the characteristics of reflux (liquid or gas). To compare the value of pH monitoring and MII for diagnosis of GER in children who present with refractory respiratory symptoms. A prospective study that included 37 patients, aged 4.25 ± 3.15 years, using combined MII-pH monitoring was performed. Patients were referred for investigation because of suspected GER as the etiology of recurrent respiratory diseases, including recurrent obstructive bronchitis, recurrent pneumonia, laryngitis, and chronic cough. We analyzed the percentage of time during which the pH was less than 4, the numeric and percentile values of acid, weak acid, and non-acid reflux episodes, and the values of liquid and mixed reflux. Diagnostic values were determined separately for pH monitoring and MII using Fisher's exact test. Reflux was detected in 31 patients. pH monitoring was positive in 20 patients (% time during which pH acid and weak acid reflux episodes, 3 had only acid reflux, 8 had weak acid reflux, and 3 had non-acid reflux. Sixteen patients had mixed (liquid and gas) reflux, and 14 had both liquid and mixed reflux. This study suggests that significant numbers of GER include weak acid reflux that cannot be detected by pH probes alone. The weak acid reflux could be a trigger for recurrent respiratory symptoms. Combining pH with MII monitoring is a valuable diagnostic method for diagnosing GER in children.

    Newborns sleep about 80% of the time. Gastroesophageal reflux disease is prevalent in about 10% of neonatal intensive care unit infants. Concurrent polysomnography and pH-impedance studies clarify the relationship of gastroesophageal reflux with sleep. To characterize spatiotemporal and chemical characteristics of impedance-positive gastroesophageal reflux and define symptom associations in sleep and wake states in symptomatic neonates. We hypothesized that frequency of impedance-positive gastroesophageal reflux events and their association with cardiorespiratory symptoms is greater during sleep. Eighteen neonates underwent concurrent polysomnography with a pH-impedance study. Impedance-positive gastroesophageal reflux events (weakly acidic or acidic) were categorized between sleep versus wake states: Symptom Index = number of symptoms with gastroesophageal reflux/total symptoms*100; Symptom Sensitivity Index = number of gastroesophageal reflux with symptoms/total gastroesophageal reflux*100; Symptom Association Probability = [(1 - probability of observed association between reflux and symptoms)*100]). We analyzed 317 gastroesophageal reflux events during 116 hours of polysomnography. During wake versus sleep, respectively, the median (interquartile range) frequency of impedance-positive gastroesophageal reflux was 4.9 (3.1-5.8) versus 1.4 (0.7-1.7) events/hour (P sleep is lower; however, spatiotemporal and chemical characteristics of gastroesophageal reflux and symptom-generation mechanisms are distinct. For cardiorespiratory symptoms during sleep, a lower Symptom Index entails evaluation for etiologies other than gastroesophageal reflux disease, a higher Symptom Sensitivity Index implies heightened esophageal sensitivity, and similar Symptom Association Probability indicates other mechanistic possibilities.

    Obstructive sleep apnea syndrome and laryngopharyngeal reflux are diseases with a high prevalence in the overall population; however, it remains unclear whether they are diseases with the same risk factors present in the same populations or if there is any association between them. To evaluate and determine the prevalence of laryngopharyngeal reflux in patients with moderate and severe obstructive apnea syndrome and also to determine its predictive factors. Historical cohort, cross-sectional study of patients aged 18-70 years, referred to a tertiary service Otorhinolaryngology outpatient clinic with a polysomnographic diagnosis of moderate or severe obstructive sleep apnea syndrome. The reflux symptom index questionnaire and the reflux finding score at indirect videolaryngoscopy were applied to the assessed population, considering the inclusion and exclusion criteria. Fifty-six patients were evaluated, of which 64.3% had a positive laryngopharyngeal reflux (positive reflux symptom index and/or positive endolaryngeal reflux finding score). Body mass index was a predictor of reflux presence in this group of patients with moderate to severe obstructive sleep apnea syndrome. In patients with positive score for endoscopic findings and reflux symptom index (12.3%), there was a trend toward significance for a higher mean apnea-hypopnea index and a higher percentage of sleep time with oxyhemoglobin saturation below 90% (p=0.05). The prevalence of laryngopharyngeal reflux was higher in this group of patients with moderate to severe obstructive sleep apnea syndrome, and the body mass index was a predictor of laryngopharyngeal reflux in these patients. There was a trend toward greater oxyhemoglobin desaturation in patients with a positive score for reflux symptoms index (RSI) and reflux finding score (RFS).

    Sensitization of esophageal chemoreceptors, either directly by intermittent acid exposure or indirectly through esophagitis-associated inflammatory mediators, is likely to be the mechanism underlying the perception of heartburn. To compare basal esophageal sensitivity with electrical stimulation and acid, and to compare the degree of acid-induced sensitization in controls and in patient groups across the entire spectrum of gastroesophageal reflux disease: erosive oesophagitis (EO), nonerosive reflux disease (NERD), and functional heartburn (FH). Esophageal sensory and pain thresholds to electrical stimulation were measured before, 30, and 60 minutes after an intraesophageal infusion of saline or HCl. Patients received a 30-minute infusion of 0.15 M HCl and controls were randomized to receive either HCl (n = 11) or saline (n = 10). After electrical sensory threshold testing, participants received another 30-minute infusion of HCl to determine whether sensitivity to acid is increased by prior acid exposure All patient groups had higher basal sensory thresholds than healthy controls (controls, 13 ± 1.4 mA; FH, 20 ± 5.1 mA; NERD, 21 ± 5.1 mA; EO, 23 ± 5.4 mA; P acid exposure reduced sensory thresholds to electrical stimulation in FH and NERD patients (P acid sensitivity during the first HCl infusion was comparable between all patient groups and controls. The secondary infusion caused increased discomfort in all participants (P acid-induced sensitization to HCl was significantly elevated in the patient groups ( P acid infusion sensitizes it to subsequent electrical and chemical stimulation. (2) The acid-related sensitization is greater in gastroesophageal reflux disease than in controls and may influence in part symptom perception in this population. (3) Acid-related sensitization within the gastroesophageal reflux disease population is not dependant on mucosal inflammation.

    To estimate esophageal and gastric pH values on an empty stomach and after stimulation of gastric secretion and gastric and duodenal motor-evacuatory activity in patients with gastroesophageal reflux disease (GERD) associated with pathological refluxes, such as gastroesophageal reflux (GER) and duodenogastroesophageal reflux (DGER). The observational cross-sectional study was conducted to investigate and compare the parameters of intraesophageal and intragastric pH metry and peripheral electrogastroenterography in 103 GERD patients with endoscopically positive distal reflux esophagitis in GER and DGER. The patients with GERD developed pathological esophageal refluxes (both GER and DGER) in various degrees of impaired gastric production, from anacidity to hyperacidity. The patients with predominant DGER were found to have gastric hyperacidity and normal acidity slightly less frequently than those with predominant GER. The patients with GERD developing in the presence of predominant GER had moderate gastric stasis with discoordinated antroduodenal propulsion resulting from hypomotor dyskinesia of the stomach and duodenum. When DGER was predominant in the patients with GERD, the signs of gastric stasis and duodenal hyperkinesia were concurrent with discoordinated antroduodenal and duodenojejunal propulsion. The specific features of the esophagogastroduodenal secretory and motor evacuatory disorders found create conditions for the pathological refluxes into the esophagus, which differ in the composition of refluxate.
