Background
More than one decade ago, rising cases of ischemic colitis (IC) prompted the Federal Drug Administration to revoke alosetron’s approval as treatment of irritable bowel syndrome (IBS). The aim of this study was to identify medical therapies associated with development of IC.
Methods
The Federal Adverse Event Reporting System was queried for the time between January 2004 and September 2015. We identified reports listing IC as treatment complication and extracted suspected causative and concomitantly administered drugs, indications for their use and outcomes.
Results
After eliminating duplicates, we found 2811 cases of IC (68.4 % women; 59.4 ± 0.4 years). Patients with IBS accounted for 3.9 % of the cases, mostly attributed to tegaserod or alosetron. Chemotherapeutic and immunosuppressive drugs, sex hormones, and anticoagulants were the most commonly suspected causes. Bisphosphonates, nonsteroidal anti-inflammatory drugs, antipsychotics, triptans, interferon therapy, and laxative use prior to colonoscopy were among the more commonly listed treatments. In 8 %, the adverse event contributed to the patient’s death with male sex and older age predicting fatal outcomes.
Conclusion
Beyond confirming known risks of IC, the results identified several potential culprits of ischemic colitis. This information may not only explain the development of this serious adverse event, but could also guide treatment decisions, cautioning healthcare providers when considering these agents in persons with known risk factors or other drugs that may increase their risk of IC.
