MedicalResearch.com: What is the background for this study? What are the main findings?
Response: The goal of our study was to assess whether a class of antidiabetic drugs, the dipeptidyl peptidase-4 (DPP-4) inhibitors, is associated with the risk of inflammatory bowel disease (IBD). While these drugs control blood sugar levels in patients with type 2 diabetes, there is some evidence that they may also be involved in immune function, and possibly in conditions such as IBD.
In our study, we found that the use of DPP-4 inhibitors was associated with a 75% increased risk of IBD, with the highest risk observed after three to four years of use.
MedicalResearch.com: What should readers take away from your report?
Response: We identified a novel adverse event associated with the use of DPP-4 inhibitors, which contributes to the overall safety profile of this drug class. This study also opens the door to new research to try to understand the etiology of inflammatory bowel disease, and the potential role of the DPP-4 enzyme in the development of this disease.
MedicalResearch.com: What recommendations do you have for future research as a result of this work?
Response: As this is the first study assessing the relationship between the use of DPP-4 inhibitors and the risk of IBD, additional research is needed to corroborate our findings. Further studies are also needed to understand the role of the DPP-4 enzyme in the development of inflammatory bowel disease.
