• Do Symptoms of Eosinophilic Esophagitis Indicate Disease Activity?

Do Symptoms of Eosinophilic Esophagitis Indicate Disease Activity?

Lack of symptoms of eosinophilic esophagitis (EoE) does not necessarily mean a lack of disease activity, researchers report in the March issue of Gastroenterology. They found only a moderate association between symptom scores and endoscopic or histologic features of remission. EoE is a chronic, immune- or antigen-mediated esophageal disease characterized

Does IBD Increase Risk for Oral Cancer?

Patients with inflammatory bowel diseases (IBD) have an increased risk of oral cancers—especially tongue cancer—researchers report in the March issue of Clinical Gastroenterology and Hepatology. Women are at higher risk than men. Oral cancers develop in the mucosal surfaces of the lips, floor of mouth, tongue, buccal mucosa, lower and

What is the Best way to Manage Diverticulitis, and how Many People Have it?

Not all patients with multiple episodes of diverticulitis should undergo preventative surgery, shows a Markov decision model published in the January 2016 issue of Clinical Gastroenterology and Hepatology. Elective surgery after 2 episodes produces fewer quality-adjusted life-years (QALYs) than surgery after 3 episodes or conservative or medical treatments, the model found.

  • This is Your Brain on Anti-TNF Therapy

This is Your Brain on Anti-TNF Therapy

Anti-tumor necrosis factor (anti-TNF) agents rapidly reduce pain perception in brains of patients with Crohn’s disease, researchers show in the October issue of Gastroenterology. This observation could explain how clinical disease activity is often reduced long before signs of mucosal healing. Patients with Crohn’s disease treated with anti-TNF agents often report reductions in abdominal pain

  • Anemia—a Real Problem for Patients With IBD

Anemia—a Real Problem for Patients With IBD

Persistent or recurrent anemia is associated with severe and disabling inflammatory bowel disease (IBD), researchers report in the October issue of Clinical Gastroenterology and Hepatology. Persistent or recurrent anemia could be used as a marker of severe disease and to identify patients who require aggressive management. Anemia is a well-recognized but underestimated problem

6000-Calorie Diet Reveals Mechanisms of Obesity-Linked Insulin Resistance

A study in which researchers place healthy individuals on 6000-calorie per day diets has identified biologic changes that take place during the early stages of obesity and could lead to insulin resistance. The study, published in the 9 September issue of Science Translational Medicine, pinpoints oxidative stress as the potential

  • What Causes Visceral Hypersensitivity in Patients with Irritable Bowel Syndrome?

What Causes Visceral Hypersensitivity in Patients with Irritable Bowel Syndrome?

Colon tissues from patients with irritable bowel syndrome (IBS) produce increased levels of specific polyunsaturated fatty acid (PUFA) metabolites, which stimulate sensory neurons to generate visceral hypersensitivity. This occurs via activation of transient receptor potential (TRP) cation channels, researchers show in the August issue of Gastroenterology. IBS is characterized by abdominal

  • Is Fecal Calprotectin a Good Marker of Crohn’s Disease Recurrence?

Is Fecal Calprotectin a Good Marker of Crohn’s Disease Recurrence?

The fecal concentration of calprotectin can be used to monitor for recurrence of Crohn’s disease, with a high enough negative predictive value that physicians can be confident they won’t miss patients with recurrent disease, researchers report in the May issue of Gastroenterology. Approximately 80% of patients with Crohn’s disease require surgery

Special Issue: Food, the Immune System, and the GI Tract

The digestion of food and absorption of nutrients is the principal role of the gastrointestinal (GI) tract—everyone wants to know what we should eat and how it affects our body. Interactions between food and the immune system affect our microbiome, development of food allergies, nutrition, risk for inflammatory disorders or cancer, and even

  • Which Patients with Early-stage Ulcerative Colitis Have the Worst Prognoses?

Which Patients with Early-stage Ulcerative Colitis Have the Worst Prognoses?

It is a challenge to accurately identify patients with early-stage ulcerative colitis (UC) who are at highest risk for a poor outcome and therefore might require salvage therapy. In a Perspective article in the April issue of Clinical Gastroenterology and Hepatology, Walter Reinisch et al present prognostic factors for adults with newly
