## Causes

### Risk factors

The systemic use of corticosteroids in the context of inflammatory bowel disease can promote CMV infection in the colon.[1] The corticosteroids used as a primary treatment for flare-up events of inflammatory bowel disease reduce the autoimmune activity of the T lymphocytes and monocytes that contribute to the inflammation of the colon and small intestine. By inhibiting the function of these leukocytes, corticosteroids reduce the inflammation caused by IBD, but this immunosuppression enables CMV to infect the colon.[2] Similarly, use of the immunosuppressive drug that is required to decrease risk of rejection in patients who received transplant as Liver transplantation or Kidney transplantation is a risk factor for CMV infection.[3]

## Diagnosis

## Treatment

The usual treatment is antivirals, specifically ganciclovir or valganciclovir.[1] Severe CMV colitis may lead a colectomy.[4]
