Abstract
BACKGROUND Gastro-esophageal reflux disease (GERD/GORD) is a chronic condition in which gastric acid flows backwards up into the esophagus, causing heart burn and a higher disposition to esophageal cancer. The reflux is caused by impairment of the lower esophageal sphincter (LES). Over the past century gastro-esophageal reflux has become the principal gastrointestinal condition of our time. The proton pump inhibitor class of drugs is effective in ameliorating the symptoms of reflux. The cost of investigation of patients in Europe is €100 billion per annum. The cost in days lost from work is €100 billion per annum in Europe. The global cost is 3 times this amount. METHODOLOGY The proposed device for treating gastro-esophageal reflux is a biodegradable valve that is placed non surgically in the esophago-gastric junction to prevent reflux from the stomach to the esophagus. EXPERIMENT RESULTS 50 simulator studies were performed with the patented device to elucidate the most consistent method of insertion and fixation in a human like simulator. The simulator was designed to replicate the normal human gastro-esophageal anatomy and characteristics. Four animal insertions were performed under ethical regulation at Amsterdam Medical Centre, Netherlands. Three cadaveric experiments were performed at Hackensack University Hospital, New Jersey, USA, to verify the positive outcomes of the simulator studies. CONCLUSION Successful outcomes of simulator studies and cadaveric experiments allowed the design freeze of a NoReflux device for treating gastro-esophageal reflux disease.

Abstract
To report our experience with milk gastroesophageal scintigraphy and the management of gastroesophageal reflux (GER) in children. In 251 pediatric patients we recorded age, underlying disease, central nervous system (CNS) disorders, and GER management. GER management was classified based on treatment plans: grade 0, non-pharmacological treatment; grade 1, non-pharmacological but using a nasogastric tube; grade 2, pharmacological treatment; grade 3, transpyloric feeding; and grade 4, Nissen fundoplication surgery. Patients were included in classified groups with (grades 2, 3, and 4) and without (grades 0 and 1) GER treatment. We evaluated the GER height (classified based on the height of GER, grade 0; no GER, 1; GER in the lower esophagus, 2; GER in the upper esophagus), GER duration in the lower and upper esophagus, presence or absence of massive GER amounts in the lower and upper esophagus, and gastric emptying time. We compared milk scintigraphy results and patient characteristics between groups with (grades 2, 3, and 4) and without (grades 0 and 1) GER treatment. We treated 121 patients for GER. CNS disorders (presence/absence: 46/74 with vs 21/110 without treatment, P < .001). The GER height grade (1.7 ± 0.5 [range, 0-2] with vs 1.5 ± 0.7 [range, 0-2] without treatment, P = .002), massive GER amount (present/absent: 21/99 with vs 9/122 without treatment, P = .011), and duration of GER (seconds) (324.5 ± 508.3 [range, 0-1800] vs 125.0 ± 291.9 [range, 0-1750], P < .001) in the upper esophageal half differed significantly. Similarly massive GER amount (present/absent: 54/66 with vs 34/97 without treatment, P = .002) and GER duration (621.3 ± 601.0 [range, 0-1800] vs 349.8 ± 452.4 [range, 0-1800], P < .001) in the lower esophageal half differed significantly. Additionally, CNS disorders, age, and massive GER in the upper esophageal half differed significantly among grades 2 and 4 in treated patients (P < .05, P < .001, P < .05, respectively). Milk scintigraphy is useful for deciding whether GER treatment is indicated. However, the treatment plan needs to be decided based on each patient's condition.

Abstract
BACKGROUND Thoracic trauma is common, and traffic accident-related traumatic injury can cause acute stress leading to esophageal motility disorders. Interstitial cells of Cajal (ICCs) are regarded as gastrointestinal pacemaker cells. AIM This study explored the mechanism underlying changes in lower esophagus ICCs under acute stress conditions. METHODS Fifty adult rabbits, randomly divided into one healthy control and four study groups, were subjected to right chest puncture using a Hopkinson bar. Thereafter, one group was immediately subjected to lower esophagectomy, whereas the other three groups were maintained for 24, 48 and 72 h after puncture and subjected to lower esophagectomy. Immunohistochemistry was used to detect ICC distribution, morphology and density, and TUNEL assays were used to determine ICC apoptosis. Enzyme-linked immunosorbent assays (ELISAs) were used to measure cortisol, epinephrine, dopamine, IL-9, cholecystokinin (CCK) and vasoactive intestinal peptide (VIP). Western blotting and RT-PCR were performed to detect changes in SCF/c-kit and nNOS pathways. RESULTS After puncture, lung tissue was hemorrhaged, alveoli in puncture areas were destroyed, esophageal pH was decreased, and serum cortisol, epinephrine and dopamine levels increased. ICC numbers increased and apoptotic ICCs decreased in all stress groups after puncture (all p < .01). IL-9, CCK and VIP levels in lower esophagus tissue were increased after puncture (all p < .01). Moreover, SCF/c-kit and nNOS pathways were upregulated in response to stress (all p < .01). CONCLUSIONS Acute stress promotes increases in lower esophageal ICCs that might affect esophagus ICC functions and esophageal motility.

Abstract
BACKGROUND Bronchopulmonary dysplasia (BPD) may induce gastroesophageal reflux (GER). Esophageal impedance baseline values (BI) reflect mucosal inflammation. Our aim was to evaluate BI levels in preterm infants with BPD compared with those without BPD and to identify BI predictors. METHODS This is a retrospective pilot study including infants born <32 weeks' gestational age (GA) who underwent esophageal multichannel intraluminal impedance (MII)-pH. Univariate/multivariate analysis were performed to compare data between BPD and non-BPD infants and to identify BI predictors. A subgroup analysis was performed in infants born <29 weeks' GA, at highest risk for BPD. RESULTS Ninety-seven patients (median GA 285/7 weeks, mean postnatal age 49 days, 29 with BPD), were studied. BPD infants had significantly lower birth weight compared with non-BPD infants (750 vs. 1275 g), were more immature (274/7 vs. 290/7 weeks GA), were older at MII-pH (79 vs. 38 days) and received less fluids during MII-pH (147 vs. 161 ml/kg/day). The same findings were found in the group of 53 infants born <29 weeks. BPD versus non-BPD infants had significantly lower BI (2050 vs. 2574 ohm, p = 0.007) (<1000 ohm in five BPD infants vs. one non-BPD) whereas the other MII-pH parameters were not significantly different. Multiple regression analysis found that increasing chronological age was positively associated with BI (B = 9.3, p = 0.013) whereas BPD was associated with lower BI (B = -793.4, p < 0.001). CONCLUSIONS BPD versus non-BPD infants had significantly lower BI despite similar MII-pH data. BPD and chronological age predicted BI, whereas only BPD predicted BI in the most immature infants.

Abstract
The objective of the present research was to review the state of the art on the consequences of drinking coffee at the different levels of the gastrointestinal tract. At some steps of the digestive process, the effects of coffee consumption seem rather clear. This is the case for the stimulation of gastric acid secretion, the stimulation of biliary and pancreatic secretion, the reduction of gallstone risk, the stimulation of colic motility, and changes in the composition of gut microbiota. Other aspects are still controversial, such as the possibility for coffee to affect gastro-esophageal reflux, peptic ulcers, and intestinal inflammatory diseases. This review also includes a brief summary on the lack of association between coffee consumption and cancer of the different digestive organs, and points to the powerful protective effect of coffee against the risk of hepatocellular carcinoma. This review reports the available evidence on different topics and identifies the areas that would most benefit from additional studies.

Abstract
Objective: To determine and compare the clinical features and endoscopic findings of gastro-esophageal reflux disease (GERD) in elderly and younger age groups. Materials and Methods: The clinical and endoscopic features were evaluated for all patients with GERD between January 2017 and September 2020. The criteria for inclusion were being aged over 65 and under 50 years and having an upper gastrointestinal endoscopy with reflux symptoms resistant to ppi theraphy. The exclusion criteria included prior surgery, age under 18 years, and pregnancy. The diagnosis of GERD was made according to the patients' symptoms. The SPSS 11.0 for Windows pocket program was used for statistical analysis. Results: Two hundred eighty-six patients aged over 65 years and 261 patients aged below 50 years were enrolled in this study. The mean age of the older group was 68.2 ± 4.5 years and the mean age of the young group was 38 ± 7.2 years. The male/female ratio was 5/3 and 2/1 in the young and older groups, respectively. The older patients had less severe and rare typical symptoms than the young patients. However, significantly more serious endoscopic findings were noted in the older patients compared with the younger patients. Conclusion: The older and young patients with GERD were predominantly male and typical reflux problems were less common in older patients with GERD. Older patients had more important endoscopic findings such as hernia, esophagitis, and cancer.

Abstract
Functional gastro-intestinal disorders (FGIDs) impair the quality of life of many infants and their families. A formula with partial whey hydrolysate, starch, high magnesium content, prebiotic fructo-oligosaccharide and galacto-oligosaccharide and the probiotic Lactobacillus reuteri DSM 17938 was given during two weeks to 196 infants with at least two FGIDs. The efficacy was evaluated with the Cow Milk-associated Symptom Score (CoMiSS®) and quality of life with the QUALIN score. The formula was shown to decrease FGIDs within three days (decrease of CoMiSS −1.29 (3.15) (mean (SD), p < 0.0001) followed by an improvement of quality of life after seven days (increase QUALIN +1.4 (7.8); p: 0.008). Constipation decreased from 18.8% to 6.5% within three days. In combination with reassurance and guidance, the nutritional intervention was shown to be effective in infants with FGIDS in real-life circumstances.

Abstract
Gastroesophageal reflux (GER) and wheeze are two common conditions in children. GER has been advocated as a causative factor for explaining recurrent to persistent respiratory symptoms at any age. This association very often means that many children with cough, wheezing, or recurrent respiratory infections receive empirical anti-reflux medications. The causal relationship is still largely discussed. Compared to the large number of studies in infants and adolescents, literature on the relationship between GER and wheeze in preschool children is scarce and inconclusive. The aim of the present narrative review was to summarize what is known so far, and what the literature has proposed in the last 20 years, on the relationship between preschool wheezing and GER. In preschool children with respiratory symptoms there is a high rate of positivity of reflux testing, for this reason pH-MII testing and endoscopy are recommended. Flexible bronchoscopy may be useful to exclude anatomical abnormalities as the cause of wheezing in infancy and preschool years. Several biomarkers, as well as empirical anti-reflux therapy, have been proposed for the diagnosis of GER-related airway diseases, but the conclusions of these studies are controversial or even conflicting. There is a great need for future clinical trials to confirm or rule out the association.

Abstract
Introduction: Gastro-esophageal reflux disease (GERD) in infants is worldwide diagnosed with increasing frequency, resulting in an increasing number of infants exposed to treatment. In this review, we focus on the safety of therapeutic options. Areas covered: English articles were searched from 1990 until May 2020 in PubMed and Google Scholar. Evidence suggests that non-pharmacological treatment is often effective and safe. Guidelines restrict pharmacological treatment to acid-suppressive medication, which is associated with adverse effects, often related to gastro-intestinal dysbiosis and consequences of the latter. Aluminum-free alginates have some efficacy and are not associated with relevant adverse effects. Especially in infants, GERD is often nonacid related. Prokinetics are not recommended because of lack of efficacy and numerous adverse effects. Expert opinion: Pediatric trials are underpowered regarding adverse effects. The number of infants exposed to anti-secretory agents is increasing worldwide, often without indication. Informing healthcare providers about adverse effects of acid-secretory medication may contribute to a more rational use. Acid inhibiting agents such as alginates are a drug class associated with limited efficacy and devoid of serious adverse effects. Regarding prokinetics, the risk of adverse effects outweighs the benefit. Reassurance of parents and nutritional management of GERD in infants is effective and safe.

Abstract
This prospective cohort study aimed to: (1) describe types, concentrations and sensitivity profiles of bacteria found in gastric aspirates of neurologically impaired children; (2) compare flora between outpatients and those admitted with aspiration pneumonia; and (3) examine predictors of bacterial colonization. Gastric aspirates from gastrostomy fed, neurologically impaired children on antacid medication were measured for pH and sent for microbiological testing. The outpatient arm included 26 children at their baseline; the inpatient arm included 31 children with a clinical diagnosis of aspiration pneumonia. Descriptive statistics summarized the ecology and resistance patterns of microbial flora. Predictors of total bacterial colonization were explored with linear regression. High concentrations of potentially pathogenic fecal-type bacteria were detected in 50/57 (88%) gastric aspirates. pH was found to be the only predictor of bacterial growth; children with gastric pH ≥ 4 had significantly higher concentrations of aerobic growth, while those with no bacterial growth had a pH < 4. Further studies to evaluate optimal gastric pH, the role of gastric bacteria in causing aspiration pneumonia, and the optimal empiric therapy for aspiration pneumonia are recommended.

Abstract
Upper airway abnormalities increase the risk of pediatric morbidity in infants. A multidisciplinary approach to obstructive sleep apnea syndrome (OSAS) poses challenges to clinical practice. The incidence and causes of OSA are poorly studied in children under 2 years of age. To fill this gap, we performed this retrospective observational study to determine the causes of obstructive sleep apnea (OSA) in children admitted to our hospital between January 2016 and February 2018, after a brief unexplained event (BRUE) or for OSA. We reviewed the medical charts of 82 patients (39 males; BRUE n = 48; OSAS n = 34) and divided them into two age groups: < 1 year old (1–12 months; n = 59) and >1 year old (>12–24 months; n = 23). Assessment included nap polysomnography, multichannel intraluminal impedance-pH, and nasopharyngoscopy. Sleep disordered breathing was comparable between the two groups. Omega-shaped epiglottis, laryngomalacia, and nasal septum deviation were more frequent in the younger group, and nasal congestion in older group. Tonsillar and adenoidal hypertrophy was more frequent in the older group, while laryngomalacia and gastroesophageal reflux was more frequent in the younger group. Tonsil and adenoid size were associated with grade of apnea-hypopnea index severity in the older group, and laryngomalacia and gastroesophageal reflux in the younger group. The main causes of respiratory sleep disorders differ in children before or after age 1 year. Our findings have potential clinical utility for assessing the pathophysiology of obstructive sleep disordered breathing in patients less than 2 years old.

Abstract
Introduction: Various anatomical defects predispose patients with congenital diaphragmatic hernia (CDH) to develop gastroesophageal reflux disease (GERD). The fetal endoscopic tracheal occlusion (FETO) has increased the survival of patients with severe CDHs. The aim of this study was to study GERD in patients who underwent FETO. Materials and Methods: We included patients with CDH treated with or without FETO ("FETO" and "no-FETO" group, respectively) from 2013 to 2016. Data on gestational age (GA), birth weight (BW), initial observed/expected lung to head ratio (O/E LHR), final O/E LHR, duration of ventilation and hospitalization, maximal tracheal diameter, and pulmonary volume were collected. All patients underwent pH-metry after 1 year of life, and the results were compared between groups and correlated to risk factors. Results: Thirty-two patients were included in the study: 10 FETO and 22 no-FETO. No significant differences were observed in the pH-metric results of the two groups. No correlation was found between GA, BW, initial O/E LHR, maximal tracheal diameter, pulmonary volume, and pH-metric results. pH-metric results were correlated with the total duration of ventilation (R = 0.5, p = 0.003) and of hospitalization (R = 0.54, p = 0.001). Gastric herniation is associated with the worse pH-metric result. Conclusions: The FETO procedure does not seem to represent an independent risk factor for GERD. However, patients with the most severe CDH have the worst GERD.

Abstract
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.

Abstract
CONCLUSIONS It is considered that a regimen combining pharmacologic management and lifestyle modifications is the most effective treatment for laryngeal granulomas caused by GER. OBJECTIVES This study compared the results of the combination therapy and surgery to determine the best treatment of laryngeal granuloma caused by gastro-esophageal reflux in 51 patients. METHODS Prospective study. RESULTS In the conservative treatment group, the CR rate was 89.7% and recurrence rate was 2.6%, while the lesions remained in patients (7.7%). This study compared the CR and recurrence rates between conservative treatment and surgery for granuloma. The results showed that the laryngeal granuloma recurrence rate was significantly lower with the conservative treatment regimen compared with surgery (p = .0016).

Abstract
BACKGROUND Pepsin in saliva is a proposed biomarker for oropharyngeal reflux. Pepsin may be prevalent in saliva from subjects with gastro-esophageal reflux and may correlate with proximal reflux by intraluminal impedance/pH monitoring (MII/pH). METHODS Patients (3 days to 17.6 years, n=90) undergoing 24-hour MII/pH monitoring and asymptomatic controls (2 months to 13.7 years, n=43) were included. Salivary pepsin was determined using a pepsin enzyme-linked immunosorbent assay. Eight saliva samples were collected from patients undergoing 24-hr MII/pH: (i) before catheter placement, (ii) before and 30 minutes after each of three meals, and (iii) upon awakening. One sample was collected from each control. KEY RESULTS In MII/pH subjects, 85.6% (77/90) had at least one pepsin-positive sample compared with 9.3% (4/43) in controls. The range of pepsin observed in individual subjects varied widely over 24 hours. The average pepsin concentration in all samples obtained within 2 hours following the most recent reflux event was 30.7±135 ng/mL, decreasing to 16.5±39.1 ng/mL in samples collected more than 2 hours later. The frequency of pepsin-positive samples correlated significantly with symptom index (rS =0.332, P=.0014), proximal (rS =0.340, P=.0010), and distal (rS =0.272, P=.0095) MII events. CONCLUSIONS & INFERENCES Concentration of salivary pepsin may not be an accurate measure of severity of reflux because of the wide range observed in individuals over 24 hours. Saliva samples must be obtained soon after a reflux event. Defining a regimen for optimal saliva collection may help to achieve the goal of using salivary pepsin as a biomarker for oropharyngeal reflux. CLINICAL TRIAL REGISTRY NCT01091805.

Abstract
Obesity increases the risk of gastroesophageal reflux disease (GERD). The majority of the reflux attacks occur postprandially. The influence of the speed of food intake on gastroesophageal reflux events is unclear in obese patients. To determine the influence of the speed of food intake on intraesophageal reflux events in obese patients with and without GERD. A total of 26 obese female patients were recruited. The patients underwent esophageal manometry to evaluate the upper limit of the lower esophageal sphincter and subsequently placement of a Multichannel intraluminal impedance-pH (MII-pH) catheter. All patients were asked to eat the same standard meal (double cheeseburger, 1 banana, 100 g yogurt and 200 mL water; total energy value, 744 kcal; 37.6% carbohydrates, 21.2% proteins and 41.2% lipids) within 5 or 30 minutes under observation in a random order on two consecutive days. All reflux episodes over a 3-hour postprandial period were manually analyzed and compared. The mean age was 46 ± 12 (18-66) years. The mean body mass index (BMI) was 39.9 ± 8.4 kg/m2. There was no difference between the fast- and slow-eating group in the number of refluxes within the 3-postprandial hours. The patients were divided into 2 groups according to the 24-hour MII-pH monitoring results, that is, 16 subjects with normal MII-pH monitoring and 10 patients with pathologic MII-pH monitoring. There was no effect of the speed of food intake in either the patients with or without GERD. In contrast to the general belief, this study suggested that the speed of food intake does not influence the number of refluxes in obese female patients with or without GERD.

Abstract
Recently, multichannel intraluminal impedance (MII) monitoring was added to the repertoire of tests to evaluate the (patho)physiology of gastroesophageal reflux (GER) in children. Its advantage above the sole monitoring of the esophageal pH lies in the ability of the detection of both acid and nonacid GER and to discern between liquid and gas GER. Currently, combined 24 h pH-MII monitoring is recommended for evaluation of gastro-esophageal reflux disease (GERD) and its relation to symptoms in infants and children, despite the lack of reference values in these age groups. There is new evidence in the current issue of this Journal supporting the role of pH-MII monitoring for the evaluation of children presenting with gastrointestinal symptoms suggestive of GERD and the prediction of the presence of reflux esophagitis. However, several issues should be taken into account when performing pH-MII clinically.

Abstract
BACKGROUND The aim of this study was to determine the role of multichannel intraluminal impedance-pH (pH-MII) monitoring in the diagnosis of gastro-esophageal reflux disease (GERD) in children who presented with gastrointestinal (GI) symptoms in comparison with the results of pH-metry alone and endoscopy. METHODS All children who underwent pH-MII monitoring due to GI symptoms, suggestive of GERD, from October 2013 to October 2015 in Children's Hospital Zagreb, were retrospectively enrolled in the study. The cohort was divided into three groups according to age - group 1: children <1 year of age; group 2: 1-9 years of age; and group 3: ≥9 years of age. KEY RESULTS One hundred thirty-three patients met our inclusion criteria (73 female/60 male; mean age 9.2 years [0.19-18.0]). Gastro-esophageal reflux disease was determined in 44 of 133 patients (33.1%) by pH-MII and only in 21 of 133 patients (15.8%) by pH-metry alone. Endoscopy was performed in 77 (57.9%) children and esophagitis was found in 32/77 (41.6%). The finding of esophagitis significantly correlated with the number of total reflux episodes (coef. 0.42, p < 0.001), acidic (coef. 0.26, p = 0.02), weakly acidic (coef. 0.3, p = 0.008) and non-acidic (coef. 0.26, p = 0.02) reflux episodes detected by pH-MII; but, no correlation was found to reflux episodes detected by pH-metry alone (coef. 0.21, p = 0.07). CONCLUSIONS & INFERENCES Compared with pH-metry alone, pH-MII performed significantly better in the detection of GERD in all age groups. On the basis of our data, pH-MII had a strong correlation with endoscopically confirmed esophagitis.

Abstract
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.

Abstract
BACKGROUND 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. METHODS 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. RESULTS 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. CONCLUSIONS 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.

Abstract
BACKGROUND Treatment of gastro-esophageal reflux refractory symptoms is challenging. This monocenter retrospective study assessed the value of preoperative pH-impedance monitoring 'on' therapy to predict functional outcome after laparoscopic fundoplication in patients with refractory reflux symptoms. METHODS Patients with a preoperative pH-impedance monitoring 'on' proton pump inhibitors (PPIs) twice daily were assessed at least 6 months after a laparoscopic fundoplication for refractory reflux symptoms. Failure of fundoplication was defined by a Visick score > 2. Postoperative symptoms were assessed by the reflux disease questionnaire (RDQ). The pH-impedance parameters analyzed were the number of reflux events (total, acid, non-acid), esophageal acid exposure time, esophageal bolus exposure time, and symptom-reflux association defined by symptom index (SI) >50% and symptom association probability (SAP) >95%. KEY RESULTS Thirty-three patients (18 female patients, median age 46 years) were assessed after a mean follow-up of 41.3 (range 7-102.2) months. Seven (21.2%) patients were considered as failures. Compared to patients with favorable outcome, these patients were more often 'on' PPI therapy (86% vs 23%, p < 0.05) and had higher RDQ scores in each domain: heartburn (p < 0.05), regurgitation (p < 0.05) and dyspepsia (p < 0.05). A positive SAP was the only pH-impedance parameter statistically associated with successful postoperative outcome (p = 0.004). CONCLUSIONS & INFERENCES On therapy, a preoperative positive symptom association probability is the only pH-impedance parameter associated with favorable outcome after laparoscopic fundoplication for refractory reflux symptoms. These results should be confirmed by prospective studies.

Abstract
BACKGROUND A proportion of patients with foregut dysmotility fail to respond to standard interventions. Motilin agonists may be beneficial in this group. We aimed to determine the effect of camicinal, a novel motilin agonist, on gastrointestinal physiology in healthy volunteers. METHODS Healthy male subjects were randomly assigned to receive a single dose of 125 mg camicinal or placebo in a double-blind cross-over design. Esophageal function and reflux indices were assessed using high-resolution manometry (pre and 1.5-h post dose) and 24-h ambulatory multichannel intraluminal impedance/pH. After a standardized meal, subjects ingested a wireless motility capsule from which compartmental transit times and motility indices were derived. Subjects were restudied with the alternate intervention after 7 days. KEY RESULTS The study subjects (12 male, mean age 47.4 years, range 22-55) tolerated the drug well, except one who exhibited mild abdominal pain on both placebo and camicinal. In comparison to placebo, gastric emptying time (GET) was accelerated following camicinal (-115.4 min, 95% confidence interval -194.4, -36.4, p = 0.009). No effect was demonstrable on esophageal function, small bowel, colonic, or whole bowel transit times and motility indices. With camicinal, as part of a post hoc analysis, there was a trend association between the percentage reduction in GET and total number of acidic reflux events (r = 0.56, p = 0.09). CONCLUSIONS & INFERENCES Camicinal decreases GET and was generally well-tolerated. In health, the direct effects of camicinal are on accelerating GET with a potential secondary benefit of reducing reflux events, which warrant further exploration in patient cohorts.

Abstract
OBJECTIVES The cause-effect relationship between bronchial asthma and gastro-esophageal reflux (GER) is known, but studies have not been able to confirm the improvement of lung function with anti-acid therapy. Hypotensive lower esophageal sphincter (LES) may lead to both acid and non-acid reflux, resulting in asthma symptoms and decreased lung function. The objectives of our study were, firstly, to compare basal LES pressure between adult patients of asthma and normal controls and, secondly, to correlate the basal LES pressure with spirometric parameters in these patients. METHODS Thirty patients, aged between 18 and 65 years, diagnosed as cases of bronchial asthma and 27 healthy controls were included in the study. All the participants were subjected to esophageal manometry after overnight fasting and basal LES pressures were recorded. Then, spirometry was done 2 h after meal and pre- and post-bronchodilator FEV1, FVC, PEFR were obtained for the asthma group. RESULTS AND CONCLUSIONS There is significant difference between basal LES pressure in patients of bronchial asthma and control population (8.70 ± 2.67 mmHg versus 16.64 ± 5.52, p < 0.0001). 66.67% of the asthma patients have reduced LES pressures (<10 mmHg). The correlation coefficient between basal LES pressure and prebronchodilator FEV1% predicted is 0.596 (p < 0.0001, 95% CI 0.3002-0.7872). Obstructive airway impairment in adult patients of bronchial asthma is associated with hypotensive LES. GER, due to hypotensive LES may contribute to deterioration of spirometric parameters in asthma patients.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) is a popular stand-alone bariatric surgery, despite a paucity of long-term data. Hence, this study is to report the long-term outcome of LSG as primary bariatric procedure and the result of revisional surgery. METHODS With retrospective analysis of a prospective bariatric database, participants who defaulted clinic follow-up were interviewed by telephone. A total of 667 LSG was performed as primary bariatric procedure (2006-2012) with mean age of 34.5 ± 9.7 years old, female 74.7%, mean body mass index (BMI) 37.3 ± 8.1 kg/m(2). A 36-F bougie was used for all cases. RESULTS There were 61 patients available with long-term data. The weight loss outcome at 1 year, 2 years, 3 years, 4 years, and 5 years showed a mean BMI 26.3, 25.2, 25.3, 27.1, and 26.2 with mean excess weight loss (EWL) 76.0%, 79.6%, 77.3%, 73.4%, and 72.6% respectively. However, 17% patients developed de novo gastro-esophageal reflux disease (GERD). Eighteen patients (2.2%) needed surgical revisions due to weight regain (n = 6), persistent type 2 diabetes mellitus (T2DM; n = 2), stricture (n = 2), and GERD (n = 8). The revision resulted in an additional mean excess weight loss of 23.8% with mean BMI 24.9 kg/m(2) at 6 months postoperatively. There was a 23.7% mean reduction of HbA1c with one patient who was in complete diabetic remission at 1 year. CONCLUSION Our results showed LSG is a durable bariatric procedure with > 70% EWL at 5 years despite a high incidence of GERD. The need for revision of LSG is low and mainly for GERD.

Abstract
BACKGROUND Despite existing criteria for scoring gastro-esophageal reflux (GER) in esophageal multichannel pH-impedance measurement (pH-I) tracings, inter- and intra-rater variability is large and agreement with automated analysis is poor. To identify parameters of difficult to analyze pH-I patterns and combine these into a statistical model that can identify GER episodes with an international consensus as gold standard. METHODS Twenty-one experts from 10 countries were asked to mark GER presence for adult and pediatric pH-I patterns in an online pre-assessment. During a consensus meeting, experts voted on patterns not reaching majority consensus (>70% agreement). Agreement was calculated between raters, between consensus and individual raters, and between consensus and software generated automated analysis. With eight selected parameters, multiple logistic regression analysis was performed to describe an algorithm sensitive and specific for detection of GER. KEY RESULTS Majority consensus was reached for 35/79 episodes in the online pre-assessment (interrater κ = 0.332). Mean agreement between pre-assessment scores and final consensus was moderate (κ = 0.466). Combining eight pH-I parameters did not result in a statistically significant model able to identify presence of GER. Recognizing a pattern as retrograde is the best indicator of GER, with 100% sensitivity and 81% specificity with expert consensus as gold standard. CONCLUSIONS & INFERENCES Agreement between experts scoring difficult impedance patterns for presence or absence of GER is poor. Combining several characteristics into a statistical model did not improve diagnostic accuracy. Only the parameter 'retrograde propagation pattern' is an indicator of GER in difficult pH-I patterns.

Abstract
The cough reflex is modulated throughout growth and development. Cough—but not expiration reflex—appears to be absent at birth, but increases with maturation. Thus, acute cough is the most frequent respiratory symptom during the first few years of life. Later on, the pubertal development seems to play a significant role in changing of the cough threshold during childhood and adolescence resulting in sex-related differences in cough reflex sensitivity in adulthood. Asthma is the major cause of chronic cough in children. Prolonged acute cough is usually related to the long-lasting effects of a previous viral airway infection or to the particular entity called protracted bacterial bronchitis. Cough pointers and type may orient toward specific etiologies, such as barking cough in croup or tracheomalacia, paroxystic whooping cough in Pertussis. Cough is productive in protracted bacterial bronchitis, sinusitis or bronchiectasis. Cough is usually associated with wheeze or dyspnea on exertion in asthma; however, it may be the sole symptom in cough variant asthma. Thus, pediatric cough has particularities differentiating it from adult cough, so the approach and management should be developmentally specific.

Abstract
BACKGROUND Proper function of the gastro-esophageal high pressure zone is essential for the integrity of the antireflux barrier. Mechanisms include tonic contractions and the decreased tone during transient lower esophageal sphincter relaxations. METHODS We characterized the pharmacology of nicotinic receptors mediating relaxations of the human upper gastric sphincter (clasp and sling fibers) using currently available subtype selective nicotinic antagonists in tissue from organ transplant donors. Donors with either a history of gastro-esophageal reflux disease or histologic evidence of Barrett's esophagus were excluded. Clasp and sling muscle fiber strips were used for one of three paradigms. For paradigm 1, each strip was exposed to carbachol, washed, exposed to nicotinic antagonists then re-exposed to carbachol. In paradigm 2, strips were exposed to a near maximally effective bethanechol concentration then nicotine was added. Strips then were washed, exposed to nicotinic antagonists then re-exposed to bethanechol followed by nicotine. In paradigm 3, strips were exposed to bethanechol then choline or cytisine. KEY RESULTS 100 μM methyllycaconitine has no inhibitory effects on relaxations, eliminating homomeric α7 subtypes. Subtypes composed of α4β2 subunits are also eliminated because choline acts as an agonist and dihydro-beta-erythroidine is ineffective. CONCLUSIONS & INFERENCES Because mecamylamine blocks the relaxations and both choline and cytisine act as agonists in both clasp and sling fibers, the nicotinic receptor subtypes responsible for these relaxations could be composed of α3β4β2, α2β4, or α4β4 subunits.

Abstract
BACKGROUND Patients with heartburn but without esophageal erosion respond less well to proton pump inhibitors (PPIs). There is a growing body of evidence implicating the role of psychological comorbidities in producing reflux symptoms. Pain modulators improve symptoms in patients with other functional gastrointestinal disorders. We aimed to compare the efficacy of fluoxetine with omeprazole and placebo to achieve symptomatic relief in patients with heartburn and normal endoscopy who failed once daily PPIs. METHODS Endoscopy-negative patients with heartburn who failed once daily PPIs were randomly allocated to receive 6 weeks treatment of fluoxetine, omeprazole, or placebo. Random allocation was stratified according to ambulatory pH monitoring study. Percentage of heartburn-free days and symptom severity was assessed. KEY RESULTS Sixty patients with abnormal and 84 patients with normal pH test were randomized. Subjects receiving fluoxetine experienced more improvement in percentage of heartburn-free days (median 35.7, IQR 21.4-57.1) than those on omeprazole (median 7.14, IQR 0-50, p < 0.001) or placebo (median 7.14, IQR 0-33.6, p < 0.001). In normal pH subgroup, fluoxetine was superior to both omeprazole and placebo regarding percentage of heartburn-free days (median improvement, 57.1, IQR 35.7-57.1 vs 13.9, IQR, 0-45.6 and 7.14, 0-23.8, respectively, p < 0.001), but no significant difference was observed between medications in abnormal pH subgroup. CONCLUSIONS & INFERENCES Fluoxetine was superior to omeprazole for improving the symptoms of patients with heartburn and normal endoscopy who failed once daily PPIs. The superiority of fluoxetine was mostly attributed to those with normal esophageal pH rather than those with abnormal pH (ClinicalTrials.gov, number NCT01269788).

Abstract
BACKGROUND The chronic obstructive pulmonary disease (COPD) Assessment Test (CAT) is a concise health status measure for COPD. COPD patients have a variety of comorbidities, but little is known about their impact on quality of life. This study was designed to investigate comorbid factors that may contribute to high CAT scores. METHODS An observational study at Keio University and affiliated hospitals enrolled 336 COPD patients and 67 non-COPD subjects. Health status was assessed by the CAT, the St. Georges Respiratory Questionnaire (SGRQ), and all components of the Medical Outcomes Study Short-Form 36-Item (SF-36) version 2, which is a generic measure of health. Comorbidities were identified based on patients' reports, physicians' records, and questionnaires, including the Frequency Scale for the Symptoms of Gastro-esophageal reflux disease (GERD) and the Hospital Anxiety and Depression Scale. Dual X-ray absorptiometry measurements of bone mineral density were performed. RESULTS The CAT showed moderate-good correlations with the SGRQ and all components of the SF-36. The presence of GERD, depression, arrhythmia, and anxiety was significantly associated with a high CAT score in the COPD patients. CONCLUSIONS Symptomatic COPD patients have a high prevalence of comorbidities. A high CAT score should alert the clinician to a higher likelihood of certain comorbidities such as GERD and depression, because these diseases may co-exist unrecognized. TRIAL REGISTRATION Clinical trial registered with UMIN (UMIN000003470).

Abstract
The injury of the esophageal epithelium may be determined by the reflux of the gastric acid in the esophagus. Barrett's esophagus (BE) is characterized by the replacement of the normal squamous epithelium with the columnar epithelium, when the healing of the lesion occurs. According to some studies, the incidence of the esophageal adenocarcinoma in patients with BE is of about 0,5% per year. The term Barrett's esophagus is subjected to interpretation nowadays, so it lacks the clarity needed for the clinical and scientific communication on the subject of columnar metaplasia of the esophageal mucosa. The major pathogenetic factor in the development of BE is represented by the reflux disease. The cellular origin of BE is controversial and it represents an issue that needs to be resolved because it will have implications in the putative molecular mechanisms underlying the metaplastic process. The epigenetic or genetic changes, which alter protein expression, function, and/ or activity, in post-mitotic cells to drive transdifferentiation or in stem/ progenitor cells such that they are reprogrammed to differentiate into columnar rather than squamous cells, are driven by the inflammatory environment created by chronic reflux. In order to be able to develop better therapeutic strategies for the patients with this disease, an increasing interest in understanding the pathogenesis of BE at the cellular and molecular level presents these days.

Abstract
Aim: The study aimed at developing a scoring system for scintigraphic grading of gastro-esophageal reflux (GER), on gastro-esophageal reflux scintigraphy (GERS) and comparison of clinical and scintigraphic scores, pre- and post-treatment. Materials and Methods: A total of 39 cases with clinically symptomatic GER underwent 99mTc sulfur colloid GERS; scores were assigned based on the clinical and scintigraphic parameters. Post domperidone GERS was performed after completion of treatment. Follow up GERS was performed and clinical and scintigraphic parameters were compared with baseline parameters. Results: Paired t-test on pre and post domperidone treatment clinical scores showed that the decline in post-treatment scores was highly significant, with P value < 0.001. The scintigraphic scoring system had a sensitivity of 93.9% in assessing treatment response to domperidone, specificity of 83.3% i.e., 83.3% of children with no decline in scintigraphic scores show no clinical response to Domperidone. The scintigraphic scoring system had a positive predictive value of 96.9% and a negative predictive value of 71.4%. Conclusion: GERS with its quantitative parameters is a good investigation for assessing the severity of reflux and also for following children post-treatment.

Abstract
BACKGROUND Differences in lower esophageal sphincter (LES) and peristaltic function and in transient LES relaxations (TLESR) have been described in patients with gastro-esophageal reflux disease (GERD). However, some of these differences may be the result of chronic GERD rather than being an underlying contributory factor. METHODS Twins discordant for GERD symptoms, i.e., only one twin had GERD symptoms, underwent standard LES and esophageal body manometry, and then using a sleeve sensor prolonged LES and pH monitoring, 30 min before and 60 min after a 250 mL 1200 kcal lipid meal. KEY RESULTS Eight monozygotic and 24 dizygotic female twins were studied. Although there was no difference in preprandial LES pressure (symptomatic 13.2 ± 7.1 mmHg vs asymptomatic 15.1 ± 6.2 mmHg, P = 0.4), LES pressure fell further postprandially in symptomatic twins (LES pressure area under the curve 465 ± 126 vs 331 ± 141 mmHg h, P < 0.01). 12/37 (32%) of acid reflux episodes in symptomatic twins occurred due to low LES pressure or deep inspiration/strain and 0/17 in asymptomatic twins (P = 0.01). There was no difference between symptomatic and asymptomatic twins in: peristaltic amplitude, ineffective esophageal body motility, hiatus hernia prevalence, or LES length. There was also no difference in TLESR frequency preprandially (symptomatic median 1(range 0-2) vs asymptomatic 0(0-2), P = 0.08) or postprandially (2.5(1-8) vs 3(1-6), P = 0.81). CONCLUSIONS & INFERENCES Twins with GERD symptoms had lower postprandial LES pressure and given the close genetic link between the twins, it is possible that such differences are caused by GERD. Acid reflux episodes associated with a hypotensive LES were seen in symptomatic, but not in asymptomatic twins.

Abstract
About 40% of the population will experience chronic cough at some point during their lives and it tends to be more common in women (Thorax 58:901-7, 2003). Post-nasal drip (or upper airway cough syndrome), gastro-esophageal reflux disease and asthma are considered the most common causes. Yet only a small percentage of patients with these common conditions experience chronic cough. Also there is no agreed measure of post-nasal drip and controversy exists about the diagnosis of reflux above the upper esophageal sphincter (laryngopharyngeal reflux) based on observable changes to the larynx. The approach of the otolaryngologist is to consider the upper and lower airways as a continuum and that a common pathology can have an impact on all these anatomical sites.A multidisciplinary approach is advocated, utilising the skills of the respiratory physician, otolaryngologist, gastroenterologist and speech pathologist.

Abstract
GOALS To describe historical incidence trends of 2 subtypes of gastric cardia cancer. BACKGROUND The incidence of gastric cardia cancer has increased in western countries. Prior studies have treated cardia cancer as a single entity, but recent data suggest that there are 2 distinct subtypes: reflux-related and Helicobacter pylori-related. STUDY We conducted a population-based study using Connecticut Tumor Registry data from 1955 to 2007. Age-adjusted incidence rates (per 100,000 person-years) were calculated for gastric cancer, as a whole and by anatomic subsite, and for esophageal adenocarcinoma. Cardia and noncardia cancer incidence rates were further adjusted to account for cases with unspecified subsite. Mathematical formulas were derived to calculate incidence rates for reflux-related and H. pylori-related cardia cancer. RESULTS The adjusted incidence of cardia cancer was 4.0 per 100,000 in 1955 to 1959, decreased to 2.4 per 100,000 in 1965 to 1969 before increasing to 3.4 per 100,000 by 2003 to 2007. The incidence of H. pylori-related cardia cancer decreased from 3.7 to 1.0 per 100,000 over the study period, whereas reflux-related cardia cancer increased progressively from 0.3 to 2.4 per 100,000. The curves for reflux-related cardia cancer and esophageal adenocarcinoma closely mirrored each other, and their combined incidence increased from 0.5 per 100,000 in 1955 to 1959 to 5.6 per 100,000 in 2003 to 2007. CONCLUSIONS The incidence of reflux-related cardia cancer has steadily increased, whereas H. pylori-related cardia cancer has declined progressively since the mid-20th century. Trends in reflux-related cardia cancer and esophageal adenocarcinoma incidence are very similar, suggesting that these 2 cancers share a similar etiology and pathophysiological process.

Abstract
BACKGROUND The day-to-day variability in the number of reflux episodes and symptoms of gastro-esophageal reflux disease is high; therefore, the assessment of reflux disease based on 24-h monitoring may be inaccurate. AIMS The aim of the study was to compare prolonged (48 h) and standard (24 h) pH-impedance monitoring (pH-MII). METHODS Fifty-four consecutive patients with typical and atypical reflux symptoms underwent 48-h pH-MII. Acid exposure time (AET), total number of reflux episodes (TR), number of symptoms, and symptom association probability (SAP) were analyzed after the first 24 h and compared with the results obtained during 48 h of monitoring. RESULTS The differences between the fractions of patients with normal and abnormal total AET and TR on both days were not significant. The percentage of patients with positive SAP was 57.9% at 24 h and 71.9% at 48 h (difference: 14.81%, 95% CI 0.7-21.29, P<0.05). There were ten patients (10/54, 18.5%) with positive SAP after 48 h that had been negative in the first 24 h. In comparison to 24 h monitoring, patients reported a significantly increased number of various symptoms correlated with reflux after 48 h. CONCLUSIONS Extending pH-MII monitoring to 48 h does not improve the detection of abnormal acid exposure. However, it does increase the fraction of patients with positive symptom-reflux association by as much as 18.5%.

Abstract
BACKGROUND Barrett's esophagus(BE) is a premalignant condition associated with chronic gastro-esophageal reflux disease (GERD). As only a small proportion of BE progresses to malignancy, it is important to study BE prevalence to prevent adenocarcinoma. MATERIALS AND METHODS Between January 2007 and December 2010, all consecutive individuals who underwent routine upper endoscopy were prospectively recruited. Patients referred for GERD were excluded from the study. Clinical and endoscopic data were collected. RESULTS A total of 1,990 patients (mean age 47.48±13.4 years; 52.8% males) were included. Of them, 496 (24.9%) reported GERD. Erosive esophagitis (EE) was found in 221 participants (11.1%, 193 patients with LA grade A and 28 patients with LA grade B). Overall 31 of 1494 participants not reporting reflux symptoms (2.07%) suffered from silent GERD. BE was diagnosed in 75 participants (3.77%), four (5.3%) with long-segment BE and 71 (94.7%) with short-segment BE. Low-grade dysplasia was noticed in 1 patient with long-segment BE. Hiatal hernia (HH) was found in 196 patients (9.8%), and mean HH length was 3.22 ± 0.2 cm. BE was correlated to EE, GERD and the presence of HH (p= 0.0167, <0.001 and 0.017, respectively) whereas it was not associated with age, alcohol consumption and smoking (p= 0.057, 0.099 and 0.06, respectively). BE was not correlated with Helicobacter pylori infection (p=0.542). CONCLUSION The prevalence of BE was 3.77% in a Greek population undergoing upper endoscopy not referred for GERD. Long-segment BE was very uncommon (0.2%) whereas 2.07% of patients not reporting symptoms suffered from silent GERD.

Abstract
BACKGROUND AND AIM Bronchiolitis obliterans (BO) is the main pulmonary involvement resulting from sulfur mustard (SM) gas exposure that was used against Iranian civilians and military forces during the Iran-Iraq war. The present study aimed to investigate the prevalence of gastro-esophageal reflux (GER) and gastric micro-aspiration in SM gas injured patients with chronic pulmonary diseases and recurrent episodes of exacerbations. MATERIALS AND METHODS This cross-sectional study was done at Baqiyatallah University of Medical Sciences, Tehran, Iran. Gastric micro-aspiration and GER were assessed in the enrolled patients by assessing bile acids, pepsin and trypsin in their bronchoalveolar lavage fluid. RESULTS Our result showed that bile acids were found to be high in 21.4% patients, and low in 53.6% of patients. Only in 16% patients, no bile was detected in the BALF. Trypsin and pepsin were detected in BAL fluid of all patients. CONCLUSION Most of BO patients after exposure to SM suffer GER, while none the etiologic factors of GER in post lung transplant BO are present. It would be hypothesized that GER per se could be considered as an aggregative factor for exacerbations in patients. Further studies will provide more advances to better understanding of pathophysiological mechanism regarding GER and BO and treatment.

Abstract
Metabotropic glutamate receptors (mGluR) have a diverse range of structures and molecular coupling mechanisms. There are eight mGluR subtypes divided into three major groups. Group I (mGluR1 and 5) is excitatory; groups II (mGluR2 and 3) and III (mGluR 4, 6, and 7) are inhibitory. All mGluR are found in the mammalian nervous system but some are absent from sensory neurons. The focus here is on mGluR in sensory pathways from the viscera, where they have been explored as therapeutic targets. Group I mGluR are activated by endogenous glutamate or constitutively active without agonist. Constitutive activity can be exploited by inverse agonists to reduce neuronal excitability without synaptic input. This is promising for reducing activation of nociceptive afferents and pain using mGluR5 negative allosteric modulators. Many inhibitory mGluR are also expressed in visceral afferents, many of which markedly reduce excitability. Their role in visceral pain remains to be determined, but they have shown promise in inhibition of the triggering of gastro-esophageal reflux, via an action on mechanosensory gastric afferents. The extent of reflux inhibition is limited, however, and may not reach a clinically useful level. On the other hand, negative modulation of mGluR5 has very potent actions on reflux inhibition, which has produced the most likely candidates so far as therapeutic drugs. These act probably outside the central nervous system, and may therefore provide a generous therapeutic window. There are many unanswered questions about mGluR along visceral afferent pathways, the answers to which may reveal many more therapeutic candidates.

Abstract
Wheezing is common among infants and young children due to peculiar anatomical and physiological properties of their lungs. Gastro-oesophageal reflux (GER) has been incriminated as one of the cause of non-asthmatic wheezing in this age group. The present study evaluates the magnitude of GER and its causal relationship with wheezing in early childhood. All recurrent and persistent wheezers (under two years) were investigated for GER and treated medically where tests were positive. The subjects were further profiled to identify any predictors for GER. Sixty-seven children of less than 2 years age with recurrent or persistent wheezing were evaluated for GER. Mean age of the study subjects at enrolment was 10.8 months and at onset of wheezing was 7.1 (± 3.8 S.D) months. Asthma and wheeze associated lower respiratory tract infection (WALRI) was diagnosed in about 1/3 each of the patients studied. GER studies were positive in over one-third (25/67) of cases. Forty-two percent of children who wheezed by 1 year of age had a positive GER study. Interestingly, nearly half (12/25) of the patients with an abnormal study did not have any clinical suggestion of regurgitation ("silent" GERs). The severity of wheezing was higher among those who had GER versus those who did not (p ≤ 0.048; OR: 3.2). However, only 32% patients showed significant response to anti reflux treatment alone while others had partial response. GER, therefore, is an important cause for recurrent wheezing among children less than 2 years of age, either singularly or as a co-morbidity. The study findings justify investigations for GER among early wheezers; particularly for those who have onset of symptoms by 12 months of age or those who have severe disease.
