Model: Microfabricated Crypt Scaffolds for Studying Human Colon Stem Cells

Researchers created an in vitro human colon crypt array that provides an accurate representation of human intestinal crypts, reported in the February issue of Cellular and Molecular Gastroenterology and Hepatology. This system re-creates an intestinal epithelium with a high density of polarized crypts that respond in a physiologic manner to growth factors, metabolites, or

What Complications Can Arise From Percutaneous Liver Biopsy?

A unique complication of portal vein thrombosis after a percutaneous liver biopsy is reported in the January issue of Clinical Gastroenterology and Hepatology. Liver biopsies are collected to aid in diagnosis of liver disease and staging of fibrosis, but complications can include pain, bleeding, puncture of another organ, and rare events such as biliary peritonitis, sepsis and

A Case of Duodenal Ulcers from Strongyloides

Researchers describe a nearly missed case of Strongyloides infection in the April issue of Gastroenterology, had it not been for analysis of duodenal biopsies. Douglas Grunwald et al describe the case of a 74-year-old Jamaican-born woman with a 3-month history of dyspepsia, nausea, bloating, early satiety, and weight loss of 40 lbs. In

Distinguishing a Pancreatic Pseudocyst from a Mucinous Cystic Neoplasm

Researchers describe the case of a patient with what appeared to be a pancreatic pseudocyst that was found to be a benign mucinous cystic neoplasm (MCN), based on analysis of a cyst wall biopsy. In the March issue of Gastroenterology, Katie Connor et al  describe a 22-year-old woman who came

  • A Point of Care Test to Identify Patients With Celiac Disease Before Endoscopy

A Point of Care Test to Identify Patients With Celiac Disease Before Endoscopy

A rapid, point-of-care test for deamidated gliadin peptide antibody (DGP) identifies patients with celiac disease with similar levels of sensitivity and specificity as standard serologic analysis of antibodies to tissue transglutaminase (anti-tTG). Use of this test before endoscopy could identify the best candidates for duodenal biopsy analysis, leading to cost

Advance Against Hepatitis B

Long-term treatment with entecavir, an inhibitor of hepatitis B virus (HBV) replication, reduces cirrhosis and fibrosis in patients with chronic hepatitis B infection, report Eugene Schiff et al. in the March issue of Clinical Gastroenterology and Hepatology.  Patients with chronic hepatitis B can develop liver fibrosis or cirrhosis and have
