OBJECTIVES: It remains controversial whether psychosocial burden is an independent predictor of irritable bowel syndrome (IBS) or occurs concurrently as an epiphenomenon. Here we prospectively examine the individual contribution of psychosocial risk factors, demographic factors, somatic symptoms, and gastrointestinal infection within a non-clinical, IBS-free population before infection occurred. METHODS: A prospective community-based cohort study including a consecutive sample of healthy participants with an elevated risk of developing gastrointestinal infection during long-distance travel was conducted...

Infectious complications are common occurrences in end-stage liver disease (ESLD). Frequent infections precipitate decompensation of liver disease leading to acute or chronic liver failure, organ dysfunction, de-listing from transplant, and major morbidity and mortality. The spectrum of microorganisms has shifted with the emergence of multidrug-resistant strains, which has major implications for both therapy and prophylaxis. Cirrhosis is often associated with an underlying noninfectious systemic inflammatory state that makes diagnosis of infections particularly challenging...

Acute kidney injury (AKI) occurs frequently in patients with liver disease and increases morbidity and mortality. Hepatorenal syndrome is a common cause of AKI in patients with decompensated cirrhosis and is due to alterations in systemic and renal hemodynamics. Serum creatinine-based estimation of kidney function is a key component of the Model for End-stage Liver Disease score in liver transplant candidates. Continuous renal replacement therapy is used in critically ill patients with liver failure and AKI...

In the cirrhotic liver, distortion of the normal liver architecture is caused by structural and vascular changes. Portal hypertension is often associated with a hyperdynamic circulatory syndrome in which cardiac output and heart rate are increased and systemic vascular resistance is decreased. The release of several vasoactive substances is the primary factor involved in the reduction of mesenteric arterial resistance, resulting in sodium and water retention with eventual formation of ascites. Management of these patients with acute cardiac dysfunction often requires invasive hemodynamic monitoring in an intensive care unit setting to tailor decisions regarding use of fluids and vasopressors...

Hepatic encephalopathy occurs ubiquitously in all causes of advanced liver failure, however, its implications on mortality diverge and vary depending upon acuity and severity of liver failure. This associated mortality has decreased in subsets of liver failure over the last 20 years. Aside from liver transplantation, this improvement is not attributable to a single intervention but likely to a combination of practical advances in critical care management. Misconceptions surrounding many facets of hepatic encephalopathy exists due to heterogeneity in presentation, pathophysiology and outcome...

BACKGROUND & AIMS: Prophylactic antibiotics are recommended for all patients with cirrhosis hospitalized for upper gastrointestinal bleeding (UGIB). We evaluated the association between use of antibiotics, outcomes of re-admissions, and mortality in these patients. METHODS: We performed a retrospective study of 6451 patients with cirrhosis (mean age, 60.6 y) in the Veterans Affairs health care system hospitalized for UGIB from January 1, 2005, through December 31, 2013 (8655 hospitalizations)...

OBJECTIVES: Many studies around the world addressed the post-colonoscopy complications, but their pooled prevalence and time trends are unknown. We performed a systematic review and meta-analysis of population-based studies to examine the pooled prevalence of post-colonoscopy complications ("perforation", "bleeding", and "mortality"), stratified by colonoscopy indication. Temporal variability in the complication rate was assessed. METHODS: We queried Pubmed, Embase, and the Cochrane library for population-based studies examining post-colonoscopy complications (within 30 days), performed from 2001 to 2015 and published by 1 December 2015...

Vedolizumab is a novel therapeutic monoclonal antibody recently approved for the treatment of moderately to severely active ulcerative colitis and Crohn's disease in adults who have failed at least one conventional therapy. An integrin antagonist, vedolizumab binds to the α4β7 integrin which is expressed specifically by a subset of gastrointestinal-homing T lymphocytes. The binding of α4β7 integrin to mucosal addressin cell adhesion molecule-1 expressed on the surface of mucosal endothelial cells is a crucial component of the gut-selective homing mechanism for lymphocytes...

The Japanese Society of Gastroenterology revised the evidence-based clinical practice guidelines for liver cirrhosis in 2015. Eighty-three clinical questions were selected, and a literature search was performed for the clinical questions with use of the MEDLINE, Cochrane, and Igaku Chuo Zasshi databases for the period between 1983 and June 2012. Manual searching of the latest important literature was added until August 2015. The guidelines were developed with use of the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system...

Over the past 2 decades, it increasingly has been recognized that endoscopic retrograde cholangiopancreatography (ERCP) is the most predictable provocateur of acute pancreatitis, with an incidence of more than 15% in high-risk patients. For this reason, there has been considerable interest in the effect of periprocedural drug administration as well as different ERCP techniques on both the incidence and severity of post-ERCP pancreatitis. Although many agents and techniques have shown promise in small clinical studies, the majority of these have failed to yield consistent benefit in larger randomized patient groups...

Great progress has been made in the field of liver transplantation over the past two decades. This progress, however, also brings up the next set of challenges: First, organ shortage remains a major limitation, and accounts for a large proportion of wait list mortality. While living donation has successfully increased the total number of liver transplants done in Asian countries, the total number of such transplants has been stagnant in the western hemisphere. As such, there has been a significant effort over the past decade to increase the existing deceased donor pool...

Clostridium difficile infection (CDI) is now the leading cause of nosocomial infection. There has been an upsurge of CDI in patients with inflammatory bowel disease (IBD). IBD patients with CDI have increased morbidity and mortality. The establishment, proliferation, and recurrence of CDI in IBD patients form a complex interplay of microbial, environmental, and host-susceptibility factors. Different risk factors have been found predisposing IBD patients to CDI. Vancomycin performs better than metronidazole in treating IBD patients with CDI...

There has been an increase in the incidence of acute pancreatitis reported worldwide. Despite improvements in access to care, imaging and interventional techniques, acute pancreatitis continues to be associated with significant morbidity and mortality. Despite the availability of clinical practice guidelines for the management of acute pancreatitis, recent studies auditing the clinical management of the condition have shown important areas of noncompliance with evidence-based recommendations. This underscores the importance of creating understandable and implementable recommendations for the diagnosis and management of acute pancreatitis...
