Cytomegalovirus colitis in immunocompetent patients

Area of Science:

• Gastroenterology
• Infectious Diseases
• Virology

Background:

• Cytomegalovirus (CMV) is a common virus that typically causes asymptomatic or mild infections in immunocompetent individuals.
• Severe CMV manifestations are generally associated with immunocompromised states, leading to significant morbidity and mortality.
• However, rare but severe cases of CMV infection can occur in immunocompetent hosts.

Observation:

• This report describes two distinct cases of Cytomegalovirus colitis in immunocompetent patients.
• The first case involved a young male with sepsis and severe non-bloody diarrhea, who improved with specific antiviral therapy for CMV.
• The second case involved an elderly female presenting with non-specific abdominal pain and fever, which resolved spontaneously without CMV-specific treatment.

Findings:

• Cytomegalovirus colitis can present atypically in immunocompetent individuals.
• Clinical presentation and disease severity in immunocompetent patients with CMV colitis can vary significantly.
• Response to treatment may differ, with some cases resolving without specific antiviral intervention.

Implications:

• These cases underscore the importance of considering CMV as a potential cause of severe gastrointestinal symptoms, even in immunocompetent patients.
• Early diagnosis and appropriate management of CMV colitis can be crucial for improving patient outcomes.
• Further research is warranted to understand the pathogenesis and optimal management strategies for CMV infections in immunocompetent populations.
