Abstract:
Three male patients with the acquired immunodeficiency syndrome revealed perforations of the intestine (jejunum-ileum; colon ascendens; coecum). The cause was necrosis due to cytomegalovirus infection. The characteristic findings were cytomegalic inclusion bodies in endothelial cells of the capillaries. These lesions caused alterations of the microcirculation. Therefore it seems reasonable to conclude that in these cases necrosis and perforation were due to ischemia. Cytomegalovirus infection must be taken into consideration in any patient with the acquired immunodeficiency syndrome and gastrointestinal ulcerations.
Insights
Cytomegalovirus infection can cause intestinal perforations in patients with acquired immunodeficiency syndrome (AIDS). This occurs due to necrosis and ischemia, highlighting the need for considering CMV in AIDS patients with GI issues.
Area of Science:
- Gastroenterology
- Virology
- Pathology
Background:
- Acquired immunodeficiency syndrome (AIDS) is associated with various opportunistic infections.
- Gastrointestinal complications are common in individuals with advanced HIV/AIDS.
Observation:
- Three male patients with AIDS presented with intestinal perforations affecting the jejunum-ileum, ascending colon, and cecum.
- Microscopic examination revealed cytomegalic inclusion bodies within capillary endothelial cells.
Findings:
- The observed cytomegalic inclusion bodies indicate a cytomegalovirus (CMV) infection.
- CMV infection led to necrosis of the intestinal tissue.
- Lesions in microcirculation resulted in ischemia, causing necrosis and subsequent perforation.
Implications:
- Cytomegalovirus (CMV) infection should be considered a potential cause of gastrointestinal ulcerations and perforations in AIDS patients.
- Early diagnosis and management of CMV infection are crucial for preventing severe gastrointestinal complications in immunocompromised individuals.
- This study underscores the direct link between viral infections and severe organ damage in the context of immunodeficiency.
