• How Does Gastric Adenocarcinoma Develop?

How Does Gastric Adenocarcinoma Develop?

Overexpression of the peroxisome proliferator-activated receptor delta (PPARD) in gastric progenitor cells results in inflammation, dysplasia, and tumor formation in mice, researchers report in the July issue of Gastroenterology. Strategies to reduce PPARD in gastric progenitor cells might lead to treatments for stomach cancer. Gastric carcinogenesis is associated with chronic inflammation. The

  • Why Are Patients Cured of HCV Infection Still at Risk for Liver Cancer?

Why Are Patients Cured of HCV Infection Still at Risk for Liver Cancer?

Chronic infection with the hepatitis C virus (HCV) causes epigenetic changes in liver cells that alter gene expression patterns and continue to affect risk for hepatocellular carcinoma (HCC), regardless of patients’ response to direct-activating antiviral (DAA) agents, researchers report in the June issue of Gastroenterology. These alterations might be targeted

A Case of Spirochetosis That Resembles IBD

Researchers describe a patient with intestinal spirochetosis—a rare intestinal infection caused by Brachyspira aalborgi or Brachyspira pilosicoli that can involve the colon or terminal ileum and mimic inflammatory bowel diseases—in the May issue of Clinical Gastroenterology and Hepatology. Manasi Agrawal et al report the case of a 45-year-old man with HIV infection and an undetectable viral

  • Can an Antibody Against IL13 Be Used to Treat Eosinophilic Esophagitis?

Can an Antibody Against IL13 Be Used to Treat Eosinophilic Esophagitis?

A monoclonal antibody against IL13 reduced histologic and endoscopic features of eosinophilic esophagitis (EoE) in a placebo-controlled phase 2 trial, researchers report in the February issue of Gastroenterology. The antibody, called RPC4046, was well tolerated. EoE is a chronic, immune-mediated disease of the esophagus characterized by eosinophil-mediated mucosal inflammation and

  • How Can You Identify a Patient With Idiopathic Myointimal Hyperplasia of the Mesenteric Veins?

How Can You Identify a Patient With Idiopathic Myointimal Hyperplasia of the Mesenteric Veins?

Researchers report a case of vascular alterations with inflammation and evidence of venous outflow tract due to idiopathic myointimal hyperplasia of the mesenteric veins (IMHMV) in the January issue of Gastroenterology. Michiel Bronswijk et al describe a 67-year-old man with a history of obesity, type 2 diabetes, and hemochromatosis admitted to

Hazards of Very Hot Coffee

Persistent drinking of very hot coffee can cause exfoliative esophagitis due to thermal injury, researchers report in the November issue of Clinical Gastroenterology and Hepatology. Florian Schertl et al describe the case of a 55-year-old woman with new retrosternal pain upon swallowing. She had been receiving continuous and successful proton pump inhibitor

  • Effects of Diet, Intestinal Inflammation, and the Microbiome on Risk of Colorectal Cancer

Effects of Diet, Intestinal Inflammation, and the Microbiome on Risk of Colorectal Cancer

Diets that promote intestinal inflammation can increase risk of colorectal carcinomas associated with specific bacteria in the microbiome, researchers report in the October issue of Clinical Gastroenterology and Hepatology. Diet-induced intestinal inflammation alters the gut microbiome to contribute to colorectal cancer risk, which might be reduced with dietary changes. Chronic inflammation

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

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,

  • Does Mucosal Inflammation Cause Diverticulosis?

Does Mucosal Inflammation Cause Diverticulosis?

Despite limited evidence that a chronic state of low-grade mucosal inflammation contributes to development of diverticulosis, a prospective study published in the June issue of Clinical Gastroenterology and Hepatology found no correlation of the disease with mucosal inflammation, upregulated immune markers, or gastrointestinal symptoms. Colonic diverticulosis (outpouchings from the colonic lumen) is

  • Does Acute Pancreatitis Increase Risk of Pancreatic Cancer?

Does Acute Pancreatitis Increase Risk of Pancreatic Cancer?

Patients hospitalized with acute pancreatitis have a 2-fold increased risk of pancreatic cancer compared with the general population, researchers report in the May issue of Gastroenterology. Acute pancreatitis is a sudden-onset inflammatory disease of the pancreas. Although acute pancreatitis promotes development of pancreatic cancer in mouse models, there have been conflicting findings from epidemiology
