Colon ulceration in lethal cytomegalovirus infection
Abstract:
Six renal transplant recipients with severe cytomegalovirus (CMV) infection developed colonic ulceration and lower gastrointestinal bleeding. All patients died between four and 84 days following onset of bleeding. Four patients required colon resection to control blood loss. In the remaining two cases, there was complete autopsy examination with thorough tissue sampling of the colon. In addition to routine light microscopic examination, all cases were studied with an immunoperoxidase technic for identification of CMV. Electron microscopic examination of the colon was performed on two cases. In this select group of patents, CMV plays an active role in damaging colonic mucosa, primarily as a result of CMC vasculitis. Clinical and pathologic features of our cases are compared to published reports of CMV infection of the colon.

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...
