What are the Different Types of Liver Cancer, and How do They Develop?

A review article in the March issue of Gastroenterology discusses different hypotheses about the cells responsible for liver tumorigenesis. The article also reviews the different classes of liver tumors, based on the molecular features, and how these affect patient prognosis. Daniela Sia et al describe the distinct molecular and clinical features of hepatocellular

What is the Incidence of Achalasia?

The incidence of achalasia is at least twice as high as previously believed, 2 studies (one from Chicago, the other from Australia) show in the March issue of Clinical Gastroenterology and Hepatology. Achalasia is characterized by dysphagia, regurgitation of undigested food, and chest pain. Patients lose weight due to the

What is the Active Ingredient in FMT for CDI?

Sterile fecal filtrates—containing bacterial debris, proteins, antimicrobial compounds, metabolic products, and microbial DNA, rather than intact microorganisms—appear to be effective for treatment of recurrent Clostridium difficile infection (CDI), researchers report in the March issue of Gastroenterology. Fecal microbiota transplantation (FMT) is an effective therapy of recurrent CDI—a single treatment resolves

  • A New Pathway for Transmitting HBV DNA?

A New Pathway for Transmitting HBV DNA?

Extracellular vesicles carry HBV DNA as cargo that can be transmitted to other hepatocytes, researchers report in the March issue of Cellular and Molecular Gastroenterology and Hepatology. Their findings identify an antibody-neutralization–resistant route of HBV infection. Approximately 350 million people are chronically infected by HBV worldwide, and some of these

A Patient Thought to Have Cholangiocarcinoma Found to Have Rosai-Dorfman Disease

A man with sickle cell disease with generalized pain and progressive jaundice originally thought to have cholangiocarcinoma was eventually found to have Rosai-Dorfman disease, researchers report in the February issue of Clinical Gastroenterology and Hepatology. Arian Teymoorian et al describe the case of a 38-year-old black man with a history of

What are the Most Accurate Non-invasive Techniques for Measuring Liver Fibrosis and Steatosis?

Magnetic resonance elastography (MRE) is more accurate than transient elastography (TE) in identifying liver fibrosis of stage 1 or more, researchers report in the February issue of Gastroenterology, using biopsy analysis as the standard. They also show that MRI-based proton density fat fraction (MRI-PDFF) analysis is more accurate than TE-based

  • Can Your Diet Affect Your Risk for Gallstone-related Pancreatitis?

Can Your Diet Affect Your Risk for Gallstone-related Pancreatitis?

Consumption of red meat, saturated fat, and cholesterol increase risk for gallstone-related acute pancreatitis, researchers report in the February issue of Clinical Gastroenterology and Hepatology. Dietary fiber protects against acute pancreatitis—related and unrelated to gallstones—whereas coffee protects against acute pancreatitis not associated with gallstones, the study of thousands of patients

Is it Safe to Undergo Endoscopy During Pregnancy?

Endoscopy during pregnancy is associated with slight increases in risk of preterm birth and small for gestational age, but not congenital malformation or stillbirth, researchers report in a nationwide population-based cohort study published in the February issue of Gastroenterology. However, the authors believe the small increase in risk to be

  • Can Vitamin D Affect Risk of Ulcerative Colitis Relapse?

Can Vitamin D Affect Risk of Ulcerative Colitis Relapse?

Serum levels of vitamin D of 35 ng/mL or less in patients with ulcerative colitis (UC) in clinical remission are associated with disease relapse, researchers report in the February issue of Clinical Gastroenterology and Hepatology. Increasing patients’ levels of vitamin D might reduce their risk for UC relapse. Vitamin D

Video: Screening Breath Compounds to Identify Patients With Barrett’s Esophagus

Researchers can identify patients with Barrett’s esophagus (BE) based on profiles of exhaled volatile organic compounds measured with an electronic nose device. This tool, described in the January issue of Gastroenterology, provides a portable, accessible, and widely acceptable tool for screening and surveillance for BE in patients with gastroesophageal reflux
