Coffee, Beyond Caffeine

Coffee—caffeinated or decaffeinated—protects liver and gastrointestinal cells from toxic compounds, according to Sandra Kalthoff et al. in the November issue of Gastroenterology. In many epidemiology studies, coffee consumption reduced the risk of inflammation, chronic liver diseases, hepatocellular carcinoma (HCC), and other GI disorders. Its mechanisms are unclear, however, because coffee

Relief from Gastroparesis?

Gastric electrical stimulation (GES) reduces nausea and vomiting and improves quality of life in diabetic patients with gastroparesis, according to Richard W. McCallum et al. in the November issue of Clinical Gastroenterology and Hepatology. McCallum et al. studied 55 diabetic patients with gastroparesis (delayed gastric emptying, which leads to vomiting,

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

In CRC Screening, Location Matters

Colonoscopy screening reduces mortality from cancers of the distal, but not proximal, colon, according to a study published in the October issue of Gastroenterology. Harminder Singh et al. studied mortality from CRC among more than 55,000 people that had received screening colonoscopies, compared with the general population. They found that

Who Has the Greatest Risk for Colorectal Cancer?

Men and smokers have the greatest risk for developing colorectal neoplasms—even more than people with a family history of this cancer—according to Michael Hoffmeister et al. in the October issue of Clinical Gastroenterology and Hepatology. Current guidelines recommend that individuals with a family history of colorectal cancer (CRC), inflammatory bowel

How Prevalent are Pancreatic Cysts?

As more patients have undergone imaging examinations for various disorders, physicians have detected pancreatic cysts with increasing frequency. Some cysts become malignant yet many remain asymptomatic. However, the prevalence of pancreatic cysts among healthy individuals has not been established—it is important to determine how common these are, to devise strategies

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

Reflux and Laryngitis—a Complicated Relationship

Results from a large clinical trial show that proton pump inhibitors relieve some, but not all the symptoms of chronic laryngitis. One type of laryngitis, laryngopharyngeal reflux (LPR), is characterized by hoarseness, chronic cough, frequent throat clearing, and the feeling of something in the throat. Because it is believed to

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

Controlling Pancreatitis Pain

In patients with pancreatitis, treatments for the nervous system, rather than the pancreas itself, might better reduce pain, according to a study in the August issue of Clinical Gastroenterology and Hepatology. Chronic pancreatitis is painful—surgery or endoscopy to reduce pressure in the parenchyma or in the pancreatic duct does not

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

How should we assess quality of cirrhosis care?

Insurance companies and government agencies attempt to assess healthcare quality to develop quality-based reimbursement models. It is a challenge to define and measure quality of care, however, especially for complex, chronic diseases such as cirrhosis. Two studies in the August issue of Clinical Gastroenterology and Hepatology (CGH) identify tools for

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

Curbing Crohn’s for the Long Term?

Most people with Crohn’s disease receive surgery, yet the disease comes back a short time later. A study in the July issue of Clinical Gastroenterology and Hepatology reports that giving patients low doses of infliximab immediately after surgery prevents disease recurrence over long time periods. Dario Sorrentino et al. began
