• Are Prebiotics or Diets Low in FODMAPs Better for Patients With Functional GI Disorders?

Are Prebiotics or Diets Low in FODMAPs Better for Patients With Functional GI Disorders?

Intermittent administration of prebiotics might be an alternative to dietary restrictions for patients with functional gut symptoms, researchers report in the October issue of Gastroenterology. A diet low in fermentable oligo-, di-, mono-saccharides and polyols (low-FODMAP diet) reduces symptoms of irritable bowel syndrome (IBS), and patients with gas-related symptoms can significantly

  • Does Colony Stimulating Factor Increase Survival of Patients with Alcoholic Hepatitis?

Does Colony Stimulating Factor Increase Survival of Patients with Alcoholic Hepatitis?

In a pilot study from the October issue of Clinical Gastroenterology and Hepatology, colony stimulating factor 3 (CSF3, also called GCSF) improved liver function and increased survival times in patients with severe alcohol-associated hepatitis (AH), compared with standard therapy. Addition of N-acetyl cysteine (NAC) to GCSF did not improve patient outcomes. Patients

Decreased Microvilli Length, and Associated Gene Expression Changes, in Patients With Crohn’s Disease

In an analysis of intestinal tissues from patients with Crohn’s disease (CD), researchers identified specific changes in gene expression patterns that associate with histologic changes, such as differences in microvilli length. Decreased microvilli length, via decreased expression of the microvilli gene set, might contribute to epithelial malfunction and the chronic

  • How Many Cases of Drug-Induced Liver Injury Are Caused by Herbal and Dietary Supplements?

How Many Cases of Drug-Induced Liver Injury Are Caused by Herbal and Dietary Supplements?

Herbal and dietary supplement-induced liver injury is more severe than other types of drug-induced liver injury (DILI), and re-exposure is more likely, researchers report in the September issue of Clinical Gastroenterology and Hepatology. Increasing awareness of the hepatoxic effects of herbal and dietary supplements could help physicians make earlier diagnoses

  • How Does Cigarette Smoke Promote Pancreatic Tumor Development?

How Does Cigarette Smoke Promote Pancreatic Tumor Development?

Exposure to cigarette smoke activates stem cell features in pancreatic cells, via nicotinic cholinergic receptor signaling to transcription factors that activate expression of stem cell genes, researchers report in the September issue of Gastroenterology. Levels of the stem cell transcriptional regulator PAF1 are increased in pancreatic tumors from humans and

Dyspepsia and Hyperamylasemia Due to Plastic Spork Ingestion

Researchers report a case of abdominal pain and hyperamylasemia due a duodenal foreign body in the September issue of Clinical Gastroenterology and Hepatology. Lotje Korteweg et al describe the case of a 38-year old man referred for endoscopic retrograde cholangiopancreatography. A gastroduodenoscopy had been performed for chronic dyspepsia and showed

Is it Safe or Effective to Combine Therapies for Inflammatory Bowel Diseases?

Little is known about the efficacy and safety of combination targeted therapy for inflammatory bowel diseases (IBD), despite their use in treatment of other immune-mediated disorders. In a review article in the September issue of Clinical Gastroenterology and Hepatology, Robert P. Hirten et al discuss findings from studies of biologic

  • Hyperglycemia as a Marker for Early Detection of Pancreatic Cancer

Hyperglycemia as a Marker for Early Detection of Pancreatic Cancer

Patients are hyperglycemic for a mean period of 36 to 30 months before a diagnosis of pancreatic ductal adenocarcinoma (PDAC), researchers report in the August issue of Gastroenterology. This information might be used in strategies for early detection. At the time of PDAC diagnosis, approximately 85% of subjects have hyperglycemia

  • A Genetic Cause for Multiple Adenomas and Diabetes in a Young Patient

A Genetic Cause for Multiple Adenomas and Diabetes in a Young Patient

Researchers report a case of a patient with multiple adenomas and a family history of young-onset diabetes and hepatocellular carcinoma. They found these to be caused by a mutation in the HNF1 homeobox A gene (HNF1A), which caused maturity onset diabetes of the young type 3 (MODY3). Tom J. Harryvan et al evaluated a

What are the Effects of Anticoagulants in Patients With Cirrhosis and Portal Vein Thrombosis?

Vitamin K antagonists (VKAs) increase risk of minor bleeding in patients with cirrhosis given anticoagulants for portal vein thrombosis (PVT), compared to patients without cirrhosis given VKAs, researchers report in the July issue of Clinical Gastroenterology and Hepatology. However, this risk is offset by the ability of VKA to increase portal

Can Nonlytic T cells be Engineered to Fight HBV Infection?

Nonlytic T cells with receptors engineered to recognize HBV suppress virus replication in hepatocytes and limit infection of mice by activating APOBEC3, researchers report in the July issue of Gastroenterology. These cells are not hepatotoxic and might be developed for treatment of chronic HBV infection. T cells control chronic viral infections, and virus-specific

Does Mucosal Healing Mean Transmural Healing in Children With Crohn’s Disease?

 One-third of children with Crohn’s disease have healing in only the mucosa or the bowel wall (not both), researchers report in the July issue of Clinical Gastroenterology and Hepatology. Levels of fecal calprotectin below 300 μg/identify children with mucosal healing. In patients with CD, mucosal healing is associated with reduced risk of relapse,

The stomachs of competitive eaters accommodate large quantities of food by repeated rapid distension of the gastric wall during eating episodes. A Clinical Challenges and Images in GI article in the June issue of Gastroenterology presents an adverse outcome of these competitions.
