Non-Celiac Wheat Sensitivity: Distinct Clinical Condition?
A Podcast with William D. Chey, MD, FACG, and
Joseph A. Murray, MD
Recent research by Antonio Carroccio, MD, that suggests the existence of non-celiac wheat sensitivity as a distinct clinical condition is the basis for a discussion between AJG co-editor William D. Chey, MD, FACG, and Joseph A. Murray, MD, who is lead author of an upcoming clinical management guideline for celiac disease that will be published in the Red Journal. Dr. Murray helps define non-celiac gluten sensitivity, explores why gluten-free diets are unsatisfactory as a diagnostic tool, and explains the need for scientific advancement in this area. Dr. Carroccio’s paper was published in the December issue of The American Journal of Gastroenterology.

The Prevalence of Irritable Bowel Syndrome Symptoms in Inflammatory Bowel Disease
The cause of functional bowel disorders such as IBS is poorly understood but one hypothesis that has gained a lot of traction is that there is subtle inflammation in the GI tract possibly caused by a change in the gut microbiome and this leads to neuromodulation and IBS symptoms, according to AJG Journal co-editor Paul Moayyedi, MD, FACG. He talks with Alexander C. Ford, MD, and Eamonn M. M. Quigley, MD, FACG, about the findings from the first systemic review of the literature on this topic which was published early online last month. In the review, Dr. Ford and his co-investigator Stephen J. Halpin, MD, demonstrated that prevalence of symptoms compatible with IBS in patients with IBD is as high as 40%. Dr. Quigley’s editorial “Irritable Bowel Symptoms” in “IBD: Diagnostic Uncertainty Meets Pathological Reality” will be published in the October issue of the Red Journal.

New Meta-Analysis Shows No Protective Effect of 5-ASA Against CRC in IBD
Findings from a new meta-analysis focusing on non-referral studies suggest that 5-Aminosalicylic Acid offers little, if any, protection against colorectal cancer in Inflammatory Bowel Disease. In a conversation with AJG Co-Editor Dr. Paul Moayyedi, co-investigators Geoffrey C. Nguyen, MD, PhD, FRCPC and Charles N. Bernstein, MD explain why their findings conflict with previous clinic-based population studies and why 5-ASA should not be prescribed to IBD patients solely for their putative effects against CRC.

Chey, MD, Dr. Yoon K. Loke discusses his latest research findings that suggest concurrent use of antibiotics with PPIs increases the risk of CDI; and a lower risk of CDI with use of H₂RAs.
