Tracking Pancreatic Cancer Cells

Tumors spread to other parts of the body when cancer cells can escape into the bloodstream, although it is not exactly clear how they enter the circulation or decide where to form new tumors. Andrew Rhim and colleagues at the University of Pennsylvania have developed a technology to label tumor

Anti-Inflammatory Drugs Prevent Colorectal Cancer (for Some)

Aspirin and other anti-inflammatory drugs prevent colorectal cancer (CRC) in some people but not others, according to the March issue of Gastroenterology. Andrew Chan et al. found that these drugs reduce the risk of CRC only in women with high levels of soluble tumor necrosis factor receptor 2 (sTNFR-2), a

What Causes Weight Gain After Gastric Bypass?

A surgical complication, rather than eating habits, can cause patients to regain lost weight after gastric bypass surgery, reports Barham K. Abu Dayyeh et al. in the March issue of Clinical Gastroenterology and Hepatology. The authors correlated increased diameter of the gastrojejunal stoma with long-term weight gain after this common

Same Liver, New Location

Functional liver tissue can be grown in lymph nodes of mice and rescue them from lethal hepatic disease, reports Toshitaka Hoppo et al. in the February issue of Gastroenterology—lymph nodes therefore might someday be used as sites for hepatocyte transplantation in patients with end-stage liver disease. Many patients with chronic hepatic

What is the Best Strategy for Treating Pediatric Autoimmune Hepatitis?

Immunosuppressant therapy causes permanent recovery from liver failure in most children with autoimmune hepatitis (AIH), reports Miriam Cuarterolo et al. in the February issue of Clinical Gastroenterology and Hepatology. AIH is a progressive, inflammatory liver disease that predominantly affects girls before puberty. Without treatment, it progresses to cirrhosis and liver

IBD Guardian

Researchers have identified a molecule that protects colon cells from injury in a mouse model of inflammatory bowel disease (IBD). The study, published by Beth McConnell et al. in the February issue of Gastroenterology, reports that Klf5 controls genes that mediate recovery from colonic injury. Klf5 regulates transcription of genes

Are Biopsies Safe for Patients with Advanced Liver Disease?

Liver biopsies are relatively safe and well tolerated among patients with advanced chronic hepatitis C, based on data from the HALT-C trial.  Liver biopsy analysis provides information for diagnosis and planning of treatment strategies for patients with acute and chronic liver diseases, such as chronic hepatitis C infection. However, biopsies

Cadaveric Liver Cells for Transplantation?

The only effective treatment for liver failure is transplantation, which is limited by the short supply of organ donors. A study by Laura Erker et al. in the September issue of Gastroenterology reports that liver cells from human cadavers might someday be used for transplantation. Erker et al. showed that

Marking the Course of Hepatitis B

It is a challenge to monitor the course of chronic hepatitis B. Patients still carry the Hepatitis B surface antigen (HBsAg) but have varying levels of viral DNA, HBeAg, and liver inflammation—and remain at risk for developing hepatocellular carcinoma (HCC). Two papers in this month’s issue of Gastroenterology investigate Hepatitis

New Word on GERD?

Proton pump inhibitors (PPIs) are useful for treating gastroesophageal reflux disease (GERD), although heartburn completely resolves in only 40% of patients that take these drugs. Furthermore, long-term use of PPIs can increase risk for pneumonia, Clostridium difficile infection, and bone disorders, so other therapeutic strategies are needed. In the August
