Insights
This study details a rare case of cytomegalovirus (CMV) enterocolitis in an immunocompetent woman. The patient experienced gastrointestinal symptoms that resolved spontaneously, highlighting CMV
Area of Science:
- Gastroenterology
- Infectious Diseases
- Virology
Background:
- Cytomegalovirus (CMV) enterocolitis is typically observed in immunocompromised individuals.
- Defining "immunocompetent" in previous CMV enterocolitis reports has lacked standardization.
Observation:
- A 57-year-old immunocompetent woman presented with hematochezia, diarrhea, and abdominal pain.
- Colonoscopy revealed aphthoid lesions and friable mucosa throughout the colon and terminal ileum.
- Biopsy confirmed cytomegalovirus inclusion bodies, establishing the diagnosis of CMV enterocolitis.
Findings:
- The patient's symptoms and endoscopic findings significantly improved without specific antiviral therapy.
- This case represents the ninth documented instance of CMV enterocolitis in an immunocompetent individual globally.
- A clear definition of "immunocompetent individual" was established for this case.
Implications:
- CMV enterocolitis can occur in individuals without apparent immune compromise.
- Spontaneous resolution of CMV enterocolitis in immunocompetent hosts is possible.
- This case expands the understanding of CMV's potential impact on the gastrointestinal tract in diverse patient populations.
Abstract:
We report a rare case of cytomegalovirus (CMV) enterocolitis in a healthy 57-year-old woman. In March 1999, she developed hematochezia, diarrhea, and abdominal pain. Total colonoscopy on March 17th showed multiple aphthoid lesions and friable mucosa from the terminal ileum to the rectum and a shallow ulcer on the ileocecal valve. Repeat total colonoscopy on April 19th showed faded aphthoid lesions in the terminal ileum, and biopsy specimen revealed CMV inclusion bodies. Symptoms and endoscopic findings improved without any specific medication. In previous reports, the definition of "immunocompetent individual" varied. Here, we define immunocompetent individual as one who has no associated diseases, is not under immunosuppressive therapy, has no recent history of operation, is negative for human immunodeficiency virus antibody, is not pregnant, has no obvious infectious course, and is less than 70 years of age. This is the ninth report of CMV enterocolitis in an immunocompetent individual in the world literature.
