Are Mitochondria Involved in Ulcerative Colitis?

Changes in mitochondrial DNA that increase levels of ATP in the intestinal mucosa protect mice from colitis, according to the November issue of Gastroenterology. Strategies to increase mitochondrial ATP production by intestinal epithelial cells might therefore be developed to treat patients with ulcerative colitis (UC). Characteristics of UC include reduced levels

Are All Patients With IBD at Increased Risk for Colorectal Cancer?

Although inflammatory bowel disease (IBD) increases risk for colorectal cancer (CRC), the risk is only substantial among patients with long-term, extensive colitis. Furthermore, CRC risk is reduced by thiopurine therapy, according to the July issue of Gastroenterology. Laurent Beaugerie et al. collected data from 19,486 patients with IBD (60% with

How Does PSC Lead to IBD?

Many patients with primary sclerosing cholangitis (PSC) also have inflammatory bowel disease (IBD), which becomes more severe after liver transplantation, researchers report in the May issue of Clinical Gastroenterology and Hepatology. These patients might require special immunosuppressive regimens. PSC is a chronic, cholestatic liver disease that eventually leads to cirrhosis

What are the Effects of IBD Therapy During Pregnancy?

In pregnant women treated for inflammatory bowel diseases (IBD),  infliximab and adalimumab, but not certolizumab, cross the placenta and are detected in infants up to 6 months after birth, according to the March issue of Clinical Gastroenterology and Hepatology (CGH). However, they do not appear to cause birth defects, and women

Abdominal CT Radiation Risk

Patients with inflammatory bowel disease (IBD) and other gastrointestinal disorders can be exposed to high levels of radiation—mostly from abdominal computed tomography (CT) scans—reports the March issue of Clinical Gastroenterology and Hepatology. Access to high-quality facilities and technologic advances have increased the use of CT imaging of the GI tract.

An Immune Culprit in IBD?

Patients with Crohn’s disease or ulcerative colitis have reduced levels of an important regulator of the immune response—the receptor for granulocyte-macrophage colony-stimulating factor (GM-CSF)—according to a study by Jonathan Goldstein et al. in the July issue of Gastroenterology. The inflammatory bowel diseases (IBD) ulcerative colitis and Crohn’s disease arise from

IBD Risk Beyond the Bowel

Venous thromboembolism (VTE) is a recurring problem for patients with inflammatory bowel disease (IBD), according to a clinical study by Gottfried Novacek et al. in this month’s issue of Gastroenterology. People with IBD have a high risk for developing blood clots, but it is not clear if they should receive
