Proton Pump Inhibitors May Decrease Gut Diversity, Increase C. diff Risk
MedicalResearch.com Interview with:
Dr. John K. DiBaise MD
Gastroenterology and Hepatology
Mayo Clinic, Scottsdale Arizona
Medical Research: What is the background for this study? What are the main findings?
Dr. DiBaise: Despite nearly 25 years of safe and effective use of proton pump inhibitors (PPI), in recent years there have been an increasing number of reports suggesting potentially harmful effects and harmful associations with their use. One such association with PPI use has been Clostridium difficile infection (CDI) which can cause severe and recurrent episodes of diarrhea. Previous reports evaluating the microbes present within the gastrointestinal tract (ie, gut microbiome) of individuals with CDI have shown a reduction in overall microbial community diversity. We studied the gut microbiome in healthy individuals both before and after using a proton pump inhibitors for one month and found a similar reduction in microbial diversity while taking the PPI that did not entirely revert back to the ‘normal’ baseline after being off the medication for a month. While this does not demonstrate a causal association between proton pump inhibitors use and CDI, it demonstrates that PPI use creates a situation in the gut microbial environment that may increase the individual’s susceptibility to CDI.
