Is Bariatric Surgery the Best Treatment for NAFLD?

Bariatric surgery completely resolves non-alcoholic fatty liver disease (NAFLD) in obese patients, researchers report in the May issue of Clinical Gastroenterology and Hepatology. However, The meta-analysis also found that some patients develop new or worsened features of NAFLD after these surgical weight-loss procedures. NAFLD is characterized by hepatic steatosis that

Can a Food-based Diet Replace Exclusive Enteral Nutrition for Patients With Crohn’s Disease?

An individualized, food-based diet with similar composition of nutrients to exclusive enteral nutrition (EEN), causes similar changes in the microbiomes of patients with Crohn’s disease (CD), reduces gut inflammation, and is preferred by patients, researchers report in the April issue of Gastroenterology. Non-medical treatments are needed for patients with CD. Diet

  • Can Surveillance be Extended or Eliminated for Some Patients With Barrett’s Esophagus?

Can Surveillance be Extended or Eliminated for Some Patients With Barrett’s Esophagus?

Two articles in the April issue of Clinical Gastroenterology and Hepatology show that surveillance intervals might be lengthened or even discontinued for subgroups of patients with Barrett’s esophagus. Stable non-dysplastic Barrett’s esophagus (NDBE) has a low risk of progression to high-grade dysplaisa (HGD) or esophageal adenocarcinoma (EAC), Yonne Peters et al

Is an Endoscopic Transluminal Approach Better Than Surgery for Patients With Necrotizing Pancreatitis?

An endoscopic transluminal approach for treatment of infected necrotizing pancreatitis, compared with minimally invasive surgery, significantly reduced major complications, lowered costs, and increased quality of life, according to a randomized trial published in the March issue of Gastroenterology. Acute pancreatitis is the third most common gastrointestinal disorder in the United

  • Is it Cost Effective to Transplant HCV-positive Livers Into HCV-negative Patients?

Is it Cost Effective to Transplant HCV-positive Livers Into HCV-negative Patients?

A Markov-based mathematical model estimates that transplanting hepatitis C virus (HCV)-positive livers into HCV-negative patients who have received direct-acting antiviral (DAA) agents would be cost effective and improve outcomes, researchers report in the March issue of Clinical Gastroenterology and Hepatology. There has been a steady increase in the number of

IBD Research Highlights from 2019 ECCO Congress

A variety of exciting findings from inflammatory bowel disease (IBD) research were presented at the Congress of the European Crohn’s and Colitis Organisation (ECCO), held in Copenhagen, March 7–9. Shixian Hu (Universitair Medisch Centrum Groningen, The Netherlands) reported on associations between genetic factors and the microbiome in patients with IBD.

  • REVIEW: Combining CRISPR-Cas9 and Organoid Technologies to Study Gastrointestinal Diseases

REVIEW: Combining CRISPR-Cas9 and Organoid Technologies to Study Gastrointestinal Diseases

CRISPR-Cas9 technology can be used to engineer organoids for studies of gastrointestinal development and disease pathogenesis. In the February issue of Gastroenterology, Masayuki Fujii et al review derivation of organoids from human gastrointestinal tissues and how CRISPR-Cas9 has advanced studies of the digestive system. CRISPR-Cas9 genome editing technology allows researchers to

  • REVIEW: Balancing Benefit vs Risk of Immunosuppressive Therapy for IBD

REVIEW: Balancing Benefit vs Risk of Immunosuppressive Therapy for IBD

Inflammatory bowel diseases (IBD) and their treatments, particularly immunosuppressive drugs, increase risk of infections and cancers. However, by promoting mucosal healing, these agents reduce risks of infections related to intestinal lesions, malnutrition, intravenous devices, and IBD surgeries and reduce risk of cancers associated with chronic mucosal inflammation. Laurent Beaugerie and Julien Kirchgesner

  • Can an Antibody Against IL13 Be Used to Treat Eosinophilic Esophagitis?

Can an Antibody Against IL13 Be Used to Treat Eosinophilic Esophagitis?

A monoclonal antibody against IL13 reduced histologic and endoscopic features of eosinophilic esophagitis (EoE) in a placebo-controlled phase 2 trial, researchers report in the February issue of Gastroenterology. The antibody, called RPC4046, was well tolerated. EoE is a chronic, immune-mediated disease of the esophagus characterized by eosinophil-mediated mucosal inflammation and

What are the Long-term Effects of DAA Therapy on HCV-associated Cryoglobulinemia Vasculitis?

More than 95% of patients with hepatitis C virus–associated cryoglobulinemia vasculitis (HCV-CryoVas) have a full or partial response of symptoms to treatment with direct-acting antiviral (DAA) agents, researchers report in a long-term follow-up study in the February issue of Clinical Gastroenterology and Hepatology. Fewer than 5% of patients stopped therapy

  • Combined Genetic and Clinical Data Do Not Improve Determination of Risk for Esophageal Adenocarcinoma

Combined Genetic and Clinical Data Do Not Improve Determination of Risk for Esophageal Adenocarcinoma

Addition of genetic information to clinical factors does not increase identification of individuals at risk for esophageal adenocarcinoma, researchers report in the January 2019 issue of Gastroenterology. New screening and risk evaluation methods are needed to improve early detection of esophageal adenocarcinoma, because most patients receive a diagnosis at a late

Is Endoscopic Submucosal Dissection the Best Treatment for Esophageal Cancer?

Lower proportions of patients with T1am2/m3 or T1b early-stage esophageal squamous cell carcinomas (EESCCs) treated with endoscopic submucosal dissection (ESD) have perioperative adverse events or disease-specific death after a median follow-up time of 21 months, researchers report in the January issue of Clinical Gastroenterology and Hepatology. The authors found no difference

Simple Process for Generating Unlimited Intestinal Stem Cells From Endoscopic Biopsies

An efficient method for cloning gastrointestinal stem cells from biopsies collected during endoscopy is reported in the January isssue of Gastroenterology. A system is needed to isolate, clone, and examine the mucosal stem cells away from confounding effects of immune, stromal, and microbe cells. Markers of stem cells such as
