BACKGROUND On-therapy impedance-pH monitoring in proton pump inhibitor (PPI)-refractory gastroesophageal reflux disease (GERD) yielded conflicting results. We aimed to assess the diagnostic value of postreflux swallow-induced peristaltic wave (PSPW) index and mean nocturnal baseline impedance (MNBI) in PPI-refractory heartburn. METHODS On-therapy(More)
The aim of the study was to characterise gastro-oesophageal reflux (GOR) in idiopathic pulmonary fibrosis (IPF). 40 consecutive IPF patients underwent pulmonary high-resolution computed tomography (HRCT) scan and impedance-pH monitoring while off antisecretory therapy. The presence of pulmonary fibrosis was assessed using validated HRCT scores. Reflux(More)
BACKGROUND AND AIMS Modifications of intestinal gas due to changes in microbiota may produce different symptoms. Our aim was to assess whether different patterns of hydrogen (H₂) and methane (CH₄) excretion were related to some intestinal disturbances. METHODS Six hundred and twenty-nine consecutive patients underwent a 50 g-glucose breath test (GBT) on(More)
AIM To evaluate the effect of a novel alginate-based compound, Faringel, in modifying reflux characteristics and controlling symptoms. METHODS In this prospective, open-label study, 40 patients reporting heartburn and regurgitation with proven reflux disease (i.e., positive impedance-pH test/evidence of erosive esophagitis at upper endoscopy) underwent 2(More)
Hypersensitive esophagus (HE) is defined by endoscopy-negative heartburn with a normal acid exposure time but positive symptom association probability (SAP) and/or symptom index (SI) on impedance–pH monitoring, and proton pump inhibitor (PPI) responsiveness. Functional heartburn (FH) is distinguished by negative SAP/SI and PPI refractoriness. The clinical(More)
A wide variety of pieces of evidence has suggested that obesity is associated with a significant increase in the risk for gastroesophageal reflux disease (GERD) symptoms and its complications. The aim of this study was to evaluate the effect of weight loss on reflux symptoms in overweight/obese patients with proven GERD. We enrolled overweight/obese(More)
Infectious complications contribute to significant patient morbidity and mortality in orthotopic liver transplant (OLT) recipients. Early central nervous system (CNS) involvement (within the first month after OLT) by infectious disease is essentially set off by aggressive surgical procedures, severe morbid conditions of the pretransplant period, initial(More)
BACKGROUND A lactose breath test (LBT) is usually used to diagnose lactase deficiency, and a lactose quick test (LQT) has been proposed as a new test on duodenal biopsies to detect this disorder. GOALS We aimed to assess the diagnostic accuracy of LBT and LQT and their ability to predict the clinical response to a lactose-free diet in patients with(More)
INTRODUCTION Studies have reported that the association between overweight and erosive oesophagitis is very strong, whilst seeming less consistent with non-erosive reflux disease. AIM We have hypothesized that this difference may be due to the heterogeneity of endoscopy-negative population. METHODS We studied 81 patients with erosive oesophagitis, 48(More)
BACKGROUND & AIMS Esophageal impedance measurements have been proposed to indicate the status of the esophageal mucosa, and might be used to study the roles of the impaired mucosal integrity and increased acid sensitivity in patients with heartburn. We compared baseline impedance levels among patients with heartburn who did and did not respond to proton(More)
