Crohn's & Colitis Foundation funds first studies on brain-gut-microbiome signatures of stress-related IBD symptom flares
Emeran A. Mayer, MD, director of the G. Oppenheimer Center for Neurobiology of Stress and Resilience, was invited to be part of the Crohn's and Colitis Foundation's Challenges in IBD 2018 Initiative, which has focused on the role of environmental triggers in IBD pathophysiology. This initiative has identified factors believed to play a role in IBD, such as diet, psychological stress, viruses and smoking. Together with Jenny Sauk, MD, medical director of the Center for Inflammatory Bowel Diseases and Jonathan P. Jacobs, MD, PhD, director of the Microbiome Core in the UCLA Microbiome Center, he received funding for one of the first studies resulting from this initiative, Brain-Gut-Microbiome Signatures of Stress-Related IBD Symptom Flares. The purpose of this longitudinal study is to identify biomarkers within the brain-gut microbiome axis that characterize a subset of IBD patients at higher risk for stress-related IBD flares. Early data provides compelling evidence of the relationship between higher stress perception and frequency of flares, as well as a measurable indicator of that subset of patients.

15-year grant renewed for additional five years - NIH SCORE (Specialized Centers of Research Excellence) U54 grant award
The University of California, Los Angeles SCORE Program, sex-related differences in brain-gut microbiome interactions in irritable bowel syndrome, was renewed for an additional five years. This SCORE proposal aims to gain a better understanding of the role of the gut microbiome and female sex hormones in the modulation of brain-gut microbiome interactions in two of the most common disorders of the gastrointestinal tract, irritable bowel syndrome and chronic functional constipation. To achieve this goal, it will study these interactions in (1) female patients during low estrogen states (perimenstrually, post menopausal); (2) by comparing these interactions to male patients and healthy control subjects; and (3) by studying gut microbial and brain mechanisms underlying the effectiveness of cognitive behavioral therapy. Results are likely to lead to significant improvements in the treatment of these disorders. The SCORE principle investigators are Emeran A. Mayer, MD, director of the G. Oppenheimer Center for Neurobiology of Stress and Resilience (CNSR) and Lin Chang, MD, co-director of CNSR. Additional SCORE investigators include Bruce Naliboff, PhD, Arpana Gupta, PhD, Jennifer Labus, PhD, Jonathan P. Jacobs, MD, PhD, Swapna Joshi, PhD, Lisa Kilpatrick, PhD, Benjamin Ellingson, PhD, and Jason Kutch, PhD.
The NIH also funded an additional SCORE Program at UCLA — sex differences in metabolism — under the direction of Karen Reue, PhD, vice chair of human genetics. Our team, listed above, plans to collaborate closely with Dr. Reue's group.

Six things for IBD patients to keep inmind whn it comes to medication, infusions, procedures and more during COVID-19
Inflammatory bowel disease, or IBD, is an umbrella term for two conditions that cause chronic inflammation of the digestive tract: Crohn's disease and ulcerative colitis. Because IBD patients are often on an immune-suppressing medication to keep their disease in remission, many want to know if they are at increased risk for contracting SARS-CoV2 -- the virus that causes COVID-19 – or of having a severe course of the coronavirus disease.

Berkeley Limketkai, MD, PhD, quoted in Time Health, Fall 2019
The lead article for the Fall 2019 issue of Time Health asked, “Are our guts getting worse?” There are many evidence-backed theories for why IBD is on the rise, but the broad adoption of the Western diet – replete with heavily processed, additive-laden and sugary foods – is one of the likeliest drivers, says Dr. Limketkai, director of clinical research for the UCLA Center for Inflammatory Bowel Diseases. “The standard American diet has a high inflammation profile, and we know it causes or contributes to a range of conditions, including obesity, diabetes and metabolic syndrome.”
