Dipeptidyl peptidase-3 is associated with severity of liver disease and circulatory complications in patients with cirrhosis.

Background: Patients with cirrhosis suffer from a complex multiorgan disturbance and their prognosis is influenced by the development of portal hypertension and systemic circulatory dysfunction. Although non-invasive techniques such as transient elastography aid in early detection, there is an unmet need for reliable markers of these clinically significant complications.

Methods: We conducted an exploratory single-center study investigating dipeptidyl peptidase-3 (DPP3) concentrations in various vascular beds in a cohort of 48 patients with cirrhosis and 16 healthy controls.

Pancreas divisum and recurrent pancreatitis: long-term results of minor papilla sphincterotomy.

Pancreas divisum (PD) is the most common congenital variant of the pancreatic ductal system and a potential cause of acute recurrent pancreatitis (ARP). Endoscopic therapy is a therapeutic option for symptomatic PD, but there is limited data on long-term results. We aimed to assess the effect of minor papilla endoscopic sphincterotomy (MiES) in the setting of ARP in patients with PD.

Endoscopic management of recurrent tracheoesophageal fistula induced by chronic use of nonsteroidal anti-inflammatory drugs: A case report and review of the literature.

Tracheoesophageal fistula (TEF) is frequently congenital and requires surgical correction. TEF can also occur secondary to malignant esophageal tumors or benign diseases and these cases are managed by endoscopic means, such as closing the defect with metallic stents. Although esophageal injury can occur secondary to nonsteroidal anti-inflammatory drugs (NSAIDs), TEF secondary to chronic NSAIDs use has not been described in the literature.

The diagnostic and prognostic value of serum endocan in patients with cirrhotic cardiomyopathy.

Background: We aimed to determine the relationship between endocan and cirrhotic cardiomyopathy.

Materials And Methods: Patients with liver cirrhosis and no heart disease were included in a prospective observational study with liver disease decompensation and death as primary outcomes.

Results: 83 cirrhotic patients were included and 32 had cirrhotic cardiomyopathy.

Vascular endothelial growth factor - key mediator of angiogenesis and promising therapeutical target in ulcerative colitis.

Ulcerative colitis (UC) is an inflammatory bowel disease, triggered by an inappropriate immune response of colonic mucosa. Angiogenesis is an important part of inflammatory process, enhancing inflammation in a vicious circle that aggravates mucosal damage and remodeling. The most important pathway for angiogenesis in ulcerative colitis involves vascular endothelial growth factor (VEGF) and endoglin (CD105) and can be used as target for adjuvant therapy in order to improve patients' outcome.

The Impact of Hypoxaemia on the Outcome in Liver Cirrhosis.

Background And Aims: Prognostic factors for poor evolution are critical in the setting of limited access to liver transplantation for patients with cirrhosis. We aimed to investigate the impact of hypoxaemia on the outcome in cirrhosis and the evolution of arterial oxygen tension during long-term follow-up in these patients.

Methods: Consecutive cirrhotic patients were prospectively enroled and followed-up in our tertiary referral center.

Usefulness of virtual chromoendoscopy in the evaluation of subtle small bowel ulcerative lesions by endoscopists with no experience in videocapsule.

Background And Study Aims: In videocapsule endoscopy examination (VCE), subtle variations in mucosal hue or pattern such as those seen in ulcerations can be difficult to detect, depending on the experience of the reader. Our aim was to test whether virtual chromoendoscopy (VC) techniques, designed to enhance the contrast between the lesion and the normal mucosa, could improve the characterization of ulcerative mucosal lesions.

Patients And Methods: Fifteen trainees or young gastroenterologists with no experience in VCE were randomly assigned to evaluate 250 true ulcerative and 100 false ulcerative, difficult-to-interpret small bowel lesions, initially as white light images (WLI) and then, in a second round, with the addition of one VC setting or again as WLI, labeling them as real lesions or artifacts.

Functional dyspepsia today.

Functional dyspepsia (FD) is a disorder presenting with symptoms such as postprandial fullness, early satiety or epigastric pain. Although there is a 10 to 30% reported prevalence worldwide, there is currently no clear explanation of the pathophysiology behind this condition. Motility disorders, visceral hypersensitivity, acid disorders, Helicobacter pylori infection or psychosocial factors have all been reported to play a part in the pathophysiology of FD.
