Intercurrent cytomegalovirus colitis in a patient with ulcerative colitis
The Johns Hopkins Medical Journal
|April 1, 1975
Summary
Cytomegalovirus (CMV) colitis can occur in ulcerative colitis (UC) patients, especially those on steroids. Early detection is crucial for managing this CMV infection in UC patients.
Area of Science:
- Gastroenterology
- Virology
- Immunology
Background:
- Cytomegalovirus (CMV) infection is more prevalent in ulcerative colitis (UC) patients.
- Immunosuppressive therapy, such as prednisone, is common in UC management.
- CMV colitis can present as an acute intercurrent illness in UC patients.
Purpose of the Study:
- To report a case of acute Cytomegalovirus (CMV) colitis in an ulcerative colitis (UC) patient.
- To investigate the cellular location and characteristics of CMV infection in UC.
- To highlight the importance of diagnosing CMV colitis in UC patients.
Main Methods:
- Rectal biopsy with light and electron microscopy for CMV detection.
- Serological testing for CMV confirmation.
- Histopathological analysis of plastic-embedded tissues.
Main Results:
- CMV infection confirmed in a UC patient on prednisone therapy.
- Infected cells identified in a subendothelial location, likely macrophages.
- Epithelial and endothelial cells were not infected by CMV.
Conclusions:
- Steroid therapy and active UC inflammation may predispose patients to CMV colitis.
- Prompt diagnosis of CMV colitis in UC is vital.
- Altering immunosuppressive therapy may be necessary for CMV colitis in UC patients.
