Ibandronate-associated ischemic colitis: case report
Abstract:
Ibandronate is considered to be a safe drug, and the few reported side-effects in the digestive system are usually related to the upper gastrointestinal tract. Large bowel lesions associated to ibandronate use in humans have not been reported. We describe the case of a 52-year-old female with two episodes of lower abdominal pain after the intake of oral ibandronate. The second pain episode was followed by hematochezia with endoscopic and histological evidence of sigmoid ischemia. No other possible causes of colonic ischemia were found. After a short hospital admission, there was a complete clinical, endoscopic and histological recovery. Ibandronate was withdrawn and the patient reported no further gastrointestinal complaints. This is the first reported case of colon bleeding related to the use of Ibandronate.

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
