Background and Aims: Gastroesophageal reflux disease (GERD) is a common condition present in daily practice with a wide range of clinical phenotypes. In this line, respiratory conditions may be associated with GERD. The Romanian Societies of Gastroenterology and Neurogastroenterology, in association with the Romanian Society of Pneumology, aimed to create a guideline regarding the epidemiology, diagnosis and treatment of respiratory conditions associated with GERD., Methods: Delphi methodology was used and eleven common working groups of experts were created. The experts reviewed the literature according to GRADE criteria and formulated 34 statements and recommendations. Consensus (>80% agreement) was reached for some of the statements after all participants voted., Results: All the statements and the literature review are presented in the paper, together with their correspondent grade of evidence and the voting results. Based on >80% voting agreement, a number of 22 recommendations were postulated regarding the diagnosis and treatment of GERD-induced respiratory symptoms. The experts considered that GERD may cause bronchial asthma and chronic cough in an important number of patients through micro-aspiration and vagal-mediated tracheobronchial reflex. GERD should be suspected in patients with asthma with suboptimal controlled or after exclusion of other causes, also in nocturnal refractory cough which needs gastroenterological investigations to confirm the diagnosis. Therapeutic test with double dose proton pump inhibitors (PPI) for 3 months is also useful. GERD induced respiratory conditions are difficult to treat; however,proton pump inhibitors and laparoscopic Nissen fundoplication are endorsed for therapy., Conclusions: This guideline could be useful for the multidisciplinary management of GERD with respiratory symptoms in current practice.

Patients undergoing ablation for atrial fibrillation may be at increased risk of developing gastroesophageal reflux disease. We prospectively studied the presence of symptomatic gastroesophageal reflux disease in naïve patients who underwent atrial fibrillation ablation. Methods: The presence of typical symptoms suggestive of gastroesophageal reflux disease was clinically assessed by the gastroenterologist at baseline and at 3 months after ablation. In addition to that, all patients underwent upper gastrointestinal endoscopy. Results: Seventy-five patients were included in two groups: 46 patients who underwent atrial fibrillation ablation (study group) and 29 patients without ablation (control group). Patients with atrial fibrillation ablation were younger (57.76 ± 7.66 years versus 67.81 ± 8.52 years; p = 0.001), predominantly male (62.2% versus 33.3%; p = 0.030) and with higher body mass index (28.96 ± 3.12 kg/m2 versus 26.81 ± 5.19 kg/m2; p = 0.046). At three months after the ablation, in the study and control groups, there were 88.9% and 57.1% patients in sinus rhythm, respectively, (p = 0.009). Symptomatic gastroesophageal reflux disease was not more frequent in the study group (42.2% versus 61.9%; p = 0.220). There was no difference in terms of sinus rhythm prevalence in patients with versus without symptomatic gastroesophageal reflux disease (89.5% versus 88.5%; p = 0.709). Conclusion: In this small prospective study, typical symptoms suggestive of gastroesophageal reflux disease were not more frequent three months following atrial fibrillation ablation.

Gastroesophageal reflux disease (GERD) is one of the most commonly encountered disorders in clinical practice nowadays, with an increasing burden on healthcare systems worldwide. GERD-related respiratory symptoms such as unexplained chronic cough, bronchial asthma or chronic obstructive pulmonary disease (COPD) with frequent exacerbations often pose diagnostic and therapeutic challenges and may require a multidisciplinary approach. Moreover, a potential role of GERD as a risk factor has been proposed for chronic rejection in patients who underwent lung transplantation. Pepsin has gained considerable attention from the scientific community in the last few years as a possible surrogate biomarker for GERD. The aim of this narrative review was to provide an overview of the potential utility of pepsin detection as a marker of micro-aspiration in various biological fluids retrieved from patients with suspected GERD-induced respiratory manifestations and in lung transplant patients with allograft dysfunction. Data on the subject remains highly contradictory, and while certain studies support its applicability in investigating atypical GERD manifestations, at the moment, it would be realistic to accept a modest utility at best. A major lack of consensus persists regarding topics such as the optimal timeframe for fluid collection and cut-off values. Further research is warranted in order to address these issues.

Introduction. Multichannel intraluminal esophageal impedance combined to pH-metry (pH-MII) is a sensitive tool for evaluating gastroesophageal reflux disease (GERD). The impedance-pH monitoring diagnostic test determines the frequency of reflux episodes (both acid or nonacid and liquid, gas or mixed) and the time relationship of reflux episodes and symptoms. Extradigestive manifestations and refractory GERD are two of the main recommendations for the assessment of upper digestive tract by pH-MII. Material and method. We conducted a prospective study between January 2022 - March 2023 at our tertiary referral center in North-Eastern Romania that included 26 patients suspected of GERD. All patients were investigated through pHMII. We used a ZepHr® system from Sandhill Scientific and single-use catheters with one pH electrode and 6 impedance electrodes. Patients who underwent MII-pH testing for refractory GERD were tested on proton pump inhibitor (PPI), while patients with no previous evidence of GERD were assessed off PPI. The diagnosis of GERD and phenotypes were based on Lyon metrics. Results. Out of the 26 patients, 14 (53.8%) were male and 12 (46.2%) female, with a mean age of 48.6±13.5 years. Nineteen patients (73.07%) presented with extradigestive GERD symptoms, of whom 7 patients (36.8%) with chronic cough, 7 patients (36.8%) with chronic laryngitis, 4 patients (21.05%) with non-cardiac chest pain and 1 patient (5.26%) with bronchial asthma. The rest of 7 (26.92%) patients were investigated for refractory GERD. After the final analysis of pH-MII tracks, we found GERD in 10 (38.5%) patients, functional heartburn in 6 (23.1%) patients and hypersensitive esophagus in 3 (15.4%) patients. All the 10 patients diagnosed with GERD had acid reflux, with a mean DeMeester Score of 46.7±83.8 and a mean AET of 12.8±20.9%. The mean total number of GERD episodes was 100.3±7.5 and the mean longest reflux episode was of 53.7±85.7 minutes. Conclusion. Multichannel intraluminal esophageal impedance combined to pH-metry represents an important instrument for assessing extradigestive GERD and refractory GERD. [ABSTRACT FROM AUTHOR]
