Special Issue: Genetics, Genetic Testing, and Biomarkers of Digestive Diseases

A special issue of Gastroenterology features 14 articles discussing the genetic factors that contribute to a range of gastrointestinal (GI),  hepatobiliary, and pancreatic diseases, and how this information can be used in diagnosis and treatment of patients. An introduction to the special issue explains the value of associating diseases with specific genetic variants, which can help

A Quantitative Ultrasound Technology to Identify Patients with NAFLD and Quantify Steatohepatitis

A new quantitative ultrasound (QUS)  can accurately identify patients with non-alcoholic fatty liver disease (NAFLD) and quantify hepatic steatosis, researchers report in the July issue of Clinical Gastroenterology and Hepatology. With further validation, QUS could be an inexpensive, widely used technique to screen the general or at-risk population for NAFLD. The estimated prevalence of NAFLD

  • 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

New Approaches to IBS and IBD, But Concerns About PPIs, Highlighted at DDW

A new test to identify diarrhea-predominant irritable bowel syndrome (D-IBS) and a new class of drugs to treat ulcerative colitis were presented at Digestive Disease Week (DDW) in Washington DC, May 15–19. Researchers also warned that many residents of nursing homes are being inappropriately given proton pump inhibitors (PPIs). Mark Pimentel

Video: Which Patients with Crohn’s Disease Need a CT Scan?

Researchers have developed a system to identify patients with Crohn’s disease who do not require computed tomography (CT) evaluation, described by Shail M. Govani et al  in the October issue of Clinical Gastroenterology and Hepatology. The system uses laboratory test results to avoid CT analysis, and thereby unnecessary exposure to radiation and increased cancer risk. People who come to the emergency department with

  • Measuring MicroRNAs to Detect Pancreatic Cancer

Measuring MicroRNAs to Detect Pancreatic Cancer

Analysis of microRNAs improves cytologic analysis of pancreatic fine-needle aspirates, allowing for more accurate identification of patients with pancreatic ductal adenocarcinoma (PDAC), researchers report in the October issue of Clinical Gastroenterology and Hepatology. This improvement could reduce the number of diagnostic procedures required for patients with pancreatic masses. Endoscopic ultrasound–guided fine-needle

Does EGD Identify Causes of Abdominal Pain in Children?

Esophagogastroduodenoscopy (EGD) is a useful tool for the diagnosis of children with abdominal pain, researchers report in the June issue of Clinical Gastroenterology and Hepatology. The procedure identified disorders for which medical therapy was effective in 67% of children. Chronic abdominal pain is the most common indication for EGD in children.

  • Cancer Cells in Circulation

Cancer Cells in Circulation

Pancreatic cancer cells can be detected in patients’ circulation before tumors are discovered, researchers report in the March issue of Gastroenterology. Cancer cells have long been believed to acquire metastatic potential after large primary tumors are established. However, many patients undergoing pancreatectomy for chronic pancreatitis are found to have disseminated pancreatic

Does a Response to Proton Pump Inhibitor Therapy Indicate GERD?

Just because a patient’s upper gastrointestinal symptoms are alleviated by proton pump inhibitors (PPIs) doesn’t necessarily mean that they have gastroesophageal reflux disease (GERD), according to the December issue of Clinical Gastroenterology and Hepatology. The efficacy of PPI therapy often is tested to determine whether patients’ symptoms are acid-related and

Which Direction is Best for Enteroscopy?

Antegrade is better than retrograde enteroscopy in diagnosis and treatment of patients with small bowel disease, according to the August issue of Clinical Gastroenterology and Hepatology. Single and double balloon-assisted enteroscopy (SBE and DBE), and spiral enteroscopy (which uses a screw-like overtube), are used to evaluate and treat patients with
