CHICAGO — In this exclusive video from Digestive Disease Week, Mark Pimentel, MD, executive director of the Medically Associated Science and Technology program at Cedars Sinai, discusses his research on predicting response to Xifaxan in patients with irritable bowel syndrome.
“We think IBS, in part, is due to changes in the gut microbiome and particularly in the small bowel, and that’s where rifaximin or Xifaxan [Salix Pharmaceuticals] comes in,” he said. “What we learned at this DDW is some more information about who might respond to rifaximin.”
Although the study was large, it was difficult to identify predictors in multivariable analysis, Pimentel noted. However, younger patients were more likely to respond and have a sustained response, and univariate analysis showed more severe IBS was linked to relapsing sooner, he said.
