• Does Consumption of Certain Fatty Acids Increase Risk of Ulcerative Colitis Flares?

Does Consumption of Certain Fatty Acids Increase Risk of Ulcerative Colitis Flares?

Diets with high levels of fatty acids such as myristic acid (found in palm oil, coconut oil, and dairy fats) increased risk of flare in patients with ulcerative colitis (UC), researchers report in the September issue of Clinical Gastroenterology and Hepatology. Their findings, from a prospective study of more than 400 patients

  • Does Asthma Increase Risk for Inflammatory Bowel Diseases?

Does Asthma Increase Risk for Inflammatory Bowel Diseases?

A population-based case–control study published in the September issue of Clinical Gastroenterology and Hepatology associates asthma with later development of Crohn’s disease (CD) and with ulcerative colitis (UC). Although the etiology of asthma and inflammatory bowel diseases (IBD) are not well understood, they both involve complex interactions among genetic and environmental factors and the

  • Is Dietary Fiber OK for Patients With Crohn’s Disease or Ulcerative Colitis?

Is Dietary Fiber OK for Patients With Crohn’s Disease or Ulcerative Colitis?

Intake of dietary fiber reduces risk of disease flares in patients with Crohn’s disease, but not ulcerative colitis, researchers report in the August issue of Clinical Gastroenterology and Hepatology. Recommendations to limit dietary fiber should therefore be re-evaluated. Inflammatory bowel diseases (IBD) have been associated with an abnormal mucosal immune response to

  • Can Microbial Dysbiosis Cause Colonic Inflammation?

Can Microbial Dysbiosis Cause Colonic Inflammation?

Dysbiosis contributes to the pathogenesis of inflammatory bowel diseases (IBD) by altering colonic expression of genes that regulate inflammation and the immune response, researchers report in the July issue of Cellular and Molecular Gastroenterology and Hepatology. An altered intestinal microbiota composition has been associated with IBD. However, it is not

  • Can Curcumin Treat Mild-to-Moderate Ulcerative Colitis?

Can Curcumin Treat Mild-to-Moderate Ulcerative Colitis?

Addition of curcumin to mesalamine therapy increases its ability to induce clinical and endoscopic remission in patients with mild-to-moderate active ulcerative colitis (UC), researchers show in the August issue of Clinical Gastroenterology and Hepatology. Patients with mild-to-moderate UC are usually treated with oral and/or topical mesalamine. Those who do not

  • Is FMT Ready for IBD?

Is FMT Ready for IBD?

Despite promising findings from 2 studies of fecal microbiota transplantation (FMT) in patients with ulcerative colitis, the technology should remain in clinical trials and is not ready for routine practice in patients with inflammatory bowel diseases (IBD), write Ari M. Grinspan and Colleen R. Kelly in an editorial. The success of FMT

  • VEGF Signaling Prevents Senescence in Colorectal Tumors

VEGF Signaling Prevents Senescence in Colorectal Tumors

Vascular endothelial growth factor receptor-2 (VEGFR2) signaling prevents senescence of colorectal cancer cells by inactivating p21, researchers report in the July issue of Gastroenterology. Inactivation of this pathway correlates with survival of patients treated with anti-VEGF cancer drug bevacizumab. VEGF, a growth factor that has been well studied for its

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

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
