Cytomegalovirus ileitis presenting as massive rectal bleeding in infancy.

Area of Science:

• Pediatric Gastroenterology
• Infectious Diseases
• Virology

Background:

• Cytomegalovirus (CMV) is a common virus that can cause serious illness in infants, particularly those who are immunocompromised.
• Ileitis, inflammation of the small intestine, can lead to significant gastrointestinal complications.
• Zambia faces a considerable burden of both CMV and HIV infections in its pediatric population.

Observation:

• Two infants in Zambia presented with severe, life-threatening rectal bleeding.
• The bleeding was attributed to cytomegalovirus ileitis, an inflammation of the ileum caused by CMV infection.
• One infant was positive for human immunodeficiency virus (HIV), while the other was HIV-negative but had an HIV-positive mother.

Findings:

• The clinical presentation of massive rectal bleeding in infants due to CMV ileitis is a rare but severe manifestation.
• CMV ileitis can occur in both HIV-positive and HIV-negative infants, although the risk may be higher in immunocompromised individuals.
• Despite medical intervention, both infants succumbed to the severe complications of the disease.

Implications:

• This case highlights the critical need for early diagnosis and management of CMV infections in infants, especially in resource-limited settings.
• Increased awareness among healthcare providers regarding CMV ileitis as a cause of severe gastrointestinal bleeding in infants is crucial.
• Further research is needed to understand the pathogenesis and develop effective treatment strategies for CMV ileitis in pediatric populations, particularly in the context of co-infections like HIV.
