Abstract
BACKGROUND Acid reflux index (ARI) is a biomarker for gastroesophageal reflux disease (GERD). The effects of short-term proton pump inhibitor (PPI) therapy on pharyngoesophageal motility and clearance mechanisms in infants remain unknown. We hypothesized that pharyngoesophageal reflexes and response to PPI are distinct between infants with 3%-7% and >7% ARI. METHODS Secondary analysis was performed from a subset of infants who participated in a randomized controlled trial (NCT: 02486263). Infants (N = 36, 29.9 ± 4.3 weeks gestation) underwent 4 weeks of PPI therapy, 1 week of washout, and longitudinal testing to assess: (a) clinical outcomes; (b) pH-impedance and symptom metrics including ARI, distal baseline impedance, clearance time, refluxate height, symptoms, I-GERQ-R scores, symptom association probability; (c) pharyngoesophageal motility reflexes and sensory motor characteristics. Comparisons were performed between infants with 3%-7% versus >7% ARI. KEY RESULTS From the 36 hospitalized infants treated: Pharyngoesophageal reflex latencies were prolonged (p > 0.05) and duration in ARI 3%-7% group only (p = 0.01); GER frequency, proximal ascent and clearance increased (ARI 3%-7%); weight gain velocity, oral feeding success, and fine motor score decreased while length of hospital stays increased in the ARI >7% group despite the decrease in symptoms and I-GERQ-R scores. CONCLUSIONS & INFERENCES Distinct changes in pharyngoesophageal sensory motor aspects of motility and reflex mechanisms exist after using PPI therapy in infants. Contributory factors may include the effects of maturation and aerodigestive comorbidities (GERD and BPD). Controlled studies incorporating placebo are needed to delineate the effects of PPI on causal and adaptive GERD mechanisms in infants with aerodigestive and feeding-related comorbidities.

Abstract
Background The number of patients with proton pump inhibitor (PPI)-refractory reflux symptoms is underestimated since many patients resign after an unsuccessful therapy attempt. Thus, it would be useful having a non-invasive tool that can help identify true gastroesophageal reflux disease (GERD) patients in order to manage them early and properly. The GerdQ is a validated tool developed for this purpose but its applicability in PPI-refractory patients has not yet been investigated. Our aim was to investigate if reflux symptoms per se, the GerdQ and patients characteristics are suitable for non-invasive diagnosis of GERD in patients with PPI refractory reflux symptoms. Methods A total of 500 patients from a prospectively recorded data base with PPI-refractory reflux symptoms were retrospectively analyzed. All patients received comprehensive diagnostic workup including EGD, pH-impedance measurement and manometry. GERD was diagnosed according to the recent Lyon consensus. Results Of all patients enrolled in the study, 280 (56%) finally fulfilled the criteria for objectively verified GERD according to the Lyon consensus. There were no significant differences in age and gender between the patients with and without GERD, whereas the body mass index was significantly higher in the group with verified GERD, but the discriminative value was low (Welch-Test, p < .001, Cohen's d = 0.39). Furthermore, there were no significant differences in the GerdQ values between the two groups. A GerdQ cutoff value ≥ 9 resulted in a sensitivity of 43% and specificity of 57% with a positive predictive value of 56% and a negative predictive value of 44%. Conclusion Based on our study, neither symptoms and the GerdQ score nor patients' characteristics are appropriate tools to distinguish between GERD and other causes for reflux symptoms in patients with PPI-refractory reflux symptoms.

Abstract
OBJECTIVES/HYPOTHESIS To investigate the predictive capability of pepsin level in the laryngeal mucosa to the therapeutic effect of proton-pump inhibitors in patients with suspected laryngopharyngeal reflux (LPR), so as to verify whether it can be referred to as a biomarker of LPR. STUDY DESIGN Prospective case study. METHODS Sixty patients with clinical empiric LPR were enrolled, with an reflux symptom index (RSI) ≥ 13 and an reflux finding score (RFS) > 7 as screening criteria. Biopsy specimens from the interarytenoid mucosa were obtained under topical anesthesia for pepsin immunohistochemical staining. Two parameters were observed in these patients with different pepsin levels after the administration of esomeprazole for 12 weeks: the RSI and the RFS. RESULTS Among the 60 cases, 35 cases were negative or weakly positive for pepsin (Pepsin(-) group), and 25 cases were moderately positive or strongly positive for pepsin (Pepsin(+) group). After therapy, the RSI significantly decreased from 17.00 (15.00, 19.00) to 6.00 (5.00, 11.00) in the Pepsin(+) group (Z = -4.38, P < 0.01), but no difference was found in the RFS (T = 1.48, P > 0.05). No significant difference was observed in the RSI (T = 2.01, P > 0.05) or the RFS (T = 2.01, P > 0.05) in the Pepsin(-) group either before or after therapy. An improvement in the RSI ≥ 50% was taken as the standard of effective therapy. The effective rate in the Pepsin(+) group was 72.0% (18/25), while it was 14.3% (5/35) in the Pepsin(-) group. There was a significant difference in the effective rate between the two groups (χ2 = 20.55, P < 0.01). CONCLUSIONS Proton-pump inhibitors exhibited better effects in patients with higher pepsin levels in the laryngeal mucosa. Laryngeal mucosa pepsin may serve as an ideal indicator to screen patients suitable for proton-pump inhibitor therapy and a reliable biomarker to identify patients with LPR.

Abstract
The incidence of gastric polyps is increasing. It is still unclear whether use of prolonged proton pump inhibitors (PPIs) is associated with the development of gastric polyps. Here we report 4 cases of gastric polyps induced by the long-term use of PPIs. We also discuss the side effects of prolonged use of PPIs and suggest that the long-term use of PPIs may be a cause of gastric polyps.
