• Does a PNPLA3 Polymorphism Promote Fibrosis Progression in Patients with Hepatitis C?

Does a PNPLA3 Polymorphism Promote Fibrosis Progression in Patients with Hepatitis C?

A single nucleotide polymorphism (SNP) in the patatin-like phospholipase domain containing 3 gene (PNPLA3) is associated with baseline level of fibrosis and its progression, but not development of hepatocellular carcinoma (HCC), in patients with hepatitis C virus (HCV) infection, researchers report in the February issue of Clinical Gastroenterology and Hepatology.

  • What Loci Determine Susceptibility to IBD in African Americans?

What Loci Determine Susceptibility to IBD in African Americans?

Although many of the same genetic variants determine susceptibility to inflammatory bowel diseases (IBD) in Caucasians and African Americans, researchers report the identification of variants and loci not previously associated with IBD in African American populations. Analyses of these could provide insight into the pathogenesis of IBD, researchers state in

Researchers Determine how FTO Variant Increases Obesity Risk

Variants in the FTO gene have been associated with obesity and metabolic disease, but little is known about the function of its product. Researchers now show how this gene regulates body weight. FTO encodes a nuclear protein of the AlkB related non-heme iron and 2-oxoglutarate-dependent oxygenase superfamily. In the NIH

  • Should Patients Undergo Endoscopic Sphincterotomy Before Receiving Self-expandable Metallic Stents?

Should Patients Undergo Endoscopic Sphincterotomy Before Receiving Self-expandable Metallic Stents?

Endoscopic sphincterotomy (ES) provides no benefit to patients receiving self-expandable metallic stents (SEMS) for a biliary stricture caused by pancreatic cancer, researchers report in the June issue of Clinical Gastroenterology and Hepatology. The randomized controlled trial showed that ES procedure did not affect number of adverse events, SEMS patency, or

New Approaches to IBS and IBD, But Concerns About PPIs, Highlighted at DDW

A new test to identify diarrhea-predominant irritable bowel syndrome (D-IBS) and a new class of drugs to treat ulcerative colitis were presented at Digestive Disease Week (DDW) in Washington DC, May 15–19. Researchers also warned that many residents of nursing homes are being inappropriately given proton pump inhibitors (PPIs). Mark Pimentel

Video Abstract: Increased Risk of Cervical Cancer in Women with IBD

Women with ulcerative colitis or Crohn’s disease are at increased risk for cervical neoplasias, researchers report in the April issue of Clinical Gastroenterology and Hepatology. Christine Rungoe et al performed a population-based cohort study of 27,408 women with inflammatory bowel diseases (IBD). In her video abstract, she says “we observed that women with ulcerative

Veggie Diets, Especially With Fish, Cut Colorectal Cancer Risk

A vegetarian diet, especially one that includes fish, significantly reduces the risk of colorectal cancer, a large new study reports. These findings could lead to new strategies for cancer prevention. In the Adventist Health Study 2, researchers had 77,659 men and women from Seventh-day Adventist churches nationwide complete well-validated questionnaires

Video: Does Stress Cause Ulcers?

Psychological stress increases the risk for peptic ulcers, partly by affecting health risk behaviors, researchers report in the March issue of Clinical Gastroenterology and Hepatology. Although peptic ulcers are considered to be caused by stress, Helicobacter pylori and nonsteroidal anti-inflammatory drugs (NSAIDs) took over as the accepted causes. However, less than a third of peptic ulcers develop in people

  • How Does Smoking Lead to Pancreatic Cancer?

How Does Smoking Lead to Pancreatic Cancer?

Nicotine promotes pancreatic carcinogenesis by disrupting signaling and transcriptional pathways to cause dedifferentiation of acinar cells, researchers report in the November issue of Gastroenterology. One fourth of all deaths from pancreatic ductal adenocarcinoma (PDAC) are associated with tobacco use, and heavy smoking increases risk for PDAC 6-fold. Although smokers develop PDAC

Video: Risk of Upper Gastrointestinal Bleeding From Different Drug Combinations

Combined use of nonselective nonsteroidal anti-inflammatory drugs (nNSAIDs), COX-2 selective inhibitors, or low-dose aspirin with selective serotonin reuptake inhibitors significantly increases the risk of upper gastrointestinal (GI) bleeding, researchers report in the October issue of Gastroenterology. In their case series analysis of data from 114,835 patients with upper GI bleeding (930,888 person-years of follow-up),
