Cytomegalovirus colitis in immunocompetent hosts: A case report and literature review

Abstract

Key Clinical Message Rectal bleeding can manifest cytomegalovirus (CMV) colitis even in immunocompetent patients, which can be cured with ganciclovir treatment. Abstract Cytomegalovirus (CMV) is an opportunistic virus widely affecting immunocompromised patients. Different manifestations varied from asymptomatic in immunocompetent individuals to end organ involvement, such as colitis in those with immunodeficiency. Despite the rarity of CMV colitis in immunocompetent hosts, we should consider it when the other conditions have been excluded. In this article, we have described a case of CMV colitis in an immunocompetent host and have performed a literature review on this entity. An immunocompetent 70‐year‐old female was admitted to the hospital with recurrent rectal bleeding. After various evaluations including laboratory analysis, stool examination, and colonoscopy, we have detected superficial lesions. Pathology and polymerase chain reaction reports favored CMV involvement. Her condition continues to improve after intravenous ganciclovir infusion. Rectal bleeding can manifest CMV colitis even in immunocompetent patients, which can be cured with ganciclovir treatment.
