Christina M. Surawicz, MD, MACG, co-author of the American College of Gastroenterology's new Guidelines for the Diagnosis, Treatment, and Prevention of Clostridium difficile Infections, talks with AJG Co-editor William D. Chey, MD, FACG, about the key components of the guidelines, including the epidemiology of the disease, the criteria for diagnosis of severe C. difficile infection, and appropriate treatment regimens for both mild-to-moderate and severe disease, including fecal transplantation.

Philip O. Katz, MD, FACG and Lauren B. Gerson, MD, MSc, FACG, two authors of the American College of Gastroenterology’s new Practice Guidelines for the Diagnosis and Management of Gastroesophageal Reflux Disease (GERD), talk with AJG Co-editor Paul Moayyedi, MD, FACG, about the key components of the guidelines, including the prevalence of GERD, the recommendations for the approach to diagnosis and management, and the potential adverse events associated with PPI therapy.

The Role of Fecal Microbiota Transplant (FMT) in Treating C. difficile-A Podcast with Lawrence J. Brandt, MD, MACG The American Journal of Gastroenterology (AJG) co-editor William D. Chey, M.D., FACG, talks with Lawrence J. Brandt, MD, MACG, on the efficacy of this potentially lifesaving procedure and how the FDA's recent classification of stool as a "drug" could impact physicians who want to use FMT as treatment option for their patients. A leading pioneer in the use of fecal microbiota transplantation (FMT) in treating C. difficile infection, Dr. Brandt gave the 2012 AJG lecture that was also published in the February issue.

The American Journal of Gastroenterology (AJG) Co-Editor Paul Moayyedi, MD, FACG, talks with Henry P. Parkman, MD, FACG, of Temple University, one of the lead authors of a new clinical guideline for the management of gastroparesis. Published in the January issue of AJG, the guideline addresses the definition, diagnosis, differential diagnosis, and treatment of gastroparesis, including nutritional supplementation, glycemic control, pharmacological, endoscopic, device, and surgical therapy. Dr. Parkman provides insight on the guideline’s key recommendations, including the scientifically-based evidence behind them.

Recent research by Antonio Carroccio, MD that suggests the existence of non-celiac wheat sensitivity as a distinct clinical condition is the topic of 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 to 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.

AJG Journal co-editor Dr. Paul Moayyedi talks with William D. Chey, MD, FACG and Satish Rao, MD, PhD, FACG about to two randomized controlled trials on linaclotide in irritable bowel syndrome (IBS) published in the December issue of The American Journal of Gastroenterology. The phase 3 trials report that this new therapy significantly reduces constipation and abdominal pain associated with some kinds of IBS.

AJG Co-Editor Paul Moayyedi, MD, FACG, talks with Alexander C. Ford, MD, and Eamonn M. M. Quigley, MD, FACG, about the findings from the first systematic review of the literature of irritable bowel syndrome symptoms in inflammatory bowel disease. 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%. This article and Dr. Quigley’s editorial “Irritable Bowel Symptoms in IBD: Diagnostic Uncertainty Meets Pathological Reality” were published in the October issue of the AJG.

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.

The importance of gut microflora in digestive health and disease is the topic of a July 2012 AJG Supplement. A podcast with Mark Guest Editor Mark Pimentel, MD in conversation with Dr. Bill Chey covers post-infectious functional GI conditions, SIBO, IBS, and the role of methanogens, as well as an interesting perspective on probiotics in treating GI diseases.

Findings from a new meta-analysis portray a cautionary tale on the use of PPI therapy in patients at significant risk of C. difficile infection. In conversation with AJG Co-Editor, Dr. William D. 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.

Endotherapy for Barrett's esophagus is the featured topic of the June 2012 Author Podcast featuring Dr. Irving Waxman of the University of Chicago. In conversation with Co-Editor AJG Dr. Paul Moayyedi, Dr. Waxman reviews Barrett's surveillance and management strategies for patients with high grade dysplasia including a discussion of EMR and various ablative modalities.

Professor Peter Gibson reviews the quality of the evidence on diets high or low in poorly absorbed short-chain carbohydrates, known as FODMAPs (Fermentable Oligo-, Di- and Mono-saccharides and Polyols) and their impact on functional gastrointestinal symptoms. In a discussion with Co-Editor Dr. Bill Chey, Professor Gibson provides insights on implementing dietary approaches in the office and discusses the challenges of recognizing patients with non-celiac gluten sensitivity.

Alan N. Barkun, M.D., FACG and colleagues at McGill University Health Center in Montreal conducted a new evidence-based review on the efficacy of PPIs vs. H2RAs in recurrent GI bleeding, ICU stay, mortality, and nosocomial pneumonia.
