OBJECTIVE Non-attendance at endoscopy procedures leads to wasted resources and increased costs. The purpose of this study was to investigate the factors associated with non-attendance. MATERIAL AND METHODS All patients who attended the outpatient clinic for gastroscopy or colonoscopy examinations were included in the study. Patients who missed their(More)
UNLABELLED Acute pancreatitis (AP) is a common disorder in which ensuing serious complications may lead to a fatal outcome in patients. BACKGROUND/AIMS To describe a large series of patients with severe AP (SAP) who were admitted to our hospital and to identify factors predicting mortality. PATIENTS AND METHODS In a retrospective study, all patients(More)
AIM To evaluate the cellular synthetic ability of cytokines involved in pro- and anti-inflammatory reactions in patients with AP. METHODS Sixty-seven patients with AP (16 severe, 51 mild) and 10 controls were included in the study. Cultures of whole blood were performed in samples obtained within the first 72 h from the onset of pain. Serum levels of(More)
UNLABELLED The diagnosis of chronic pancreatitis is based on morphological and functional data. To evaluate exocrine function, the secretin-cholecystokinin test is the gold standard but this is invasive and frequently unavailable. Recently, fecal elastase-1 determination has been investigated as an indirect test of pancreatic function. OBJECTIVE To(More)
OBJECTIVE To assess the accuracy of the determination of Helicobacter pylori infection by a stool immunoassay in patients with upper-gastrointestinal bleeding (UGB) of peptic origin, in comparison with the routine histological study, serology, rapid urease and 13C-breath tests. METHODS Sixty-eight patients with endoscopically proven UGB of peptic origin(More)
OBJECTIVES We aimed at evaluating bacterial DNA (bactDNA) presence in blood of Crohn's disease (CD) patients in remission as an independent risk factor of flare at 6 months. METHODS This is a prospective, multicenter study on CD patients with Crohn's disease activity index (CDAI)<150. The primary end point was time-to-relapse as evaluated by CDAI>150 in(More)
BACKGROUND There is scarce information regarding intestinal permeability (IP) in patients with acute pancreatitis (AP) and its relationship with systemic inflammatory response and bacterial translocation (BT). AIMS To study IP in patients with mild and severe forms of AP as compared with controls and the presumed correlations between IP, the inflammatory(More)
AIM To assess the usefulness of urinary trypsinogen-2 test strip, urinary trypsinogen activation peptide (TAP), and serum and urine concentrations of the activation peptide of carboxypeptidase B (CAPAP) in the diagnosis of acute pancreatitis. METHODS Patients with acute abdominal pain and hospitalized within 24 h after the onset of symptoms were(More)
BACKGROUND Serum and urine concentrations of the activation peptide of carboxypeptidase B (CAPAP) and urinary trypsinogen activation peptide (TAP) as prognostic markers in acute pancreatitis were compared. METHOD Fifty-two patients with acute pancreatitis hospitalized within 24 hours after symptom onset were prospectively studied. Blood and urine samples(More)
AIMS We investigate the behaviour of endotoxin in patients with acute pancreatitis and its relationship with the development of complications. EXPERIMENTAL DESIGN Prospective study. PATIENTS We assessed plasmatic endotoxin and anti-core endotoxin antibodies (EndoCab IgG and IgM) levels on first and third days from admission in patients with acute(More)
