A patient with IgA vasculitis (Henoch-Schönlein) developed cytomegalovirus (CMV) enteritis due to steroid-induced immunosuppression. Ganciclovir treatment effectively resolved the gastrointestinal symptoms, highlighting the importance of monitoring for opportunistic infections during immunosuppressive therapy.
Area of Science:
- Gastroenterology
- Immunology
- Infectious Diseases
Background:
- IgA vasculitis (Henoch-Schönlein purpura) is a systemic vasculitis characterized by IgA deposition.
- Steroid therapy is a common treatment for IgA vasculitis but can lead to immunosuppression.
Observation:
- A 61-year-old man presented with purpura, abdominal pain, and hematochezia, diagnosed as IgA vasculitis.
- During reduced steroid dosage, the patient developed epigastric pain and duodenal ulcers.
- Cytomegalovirus (CMV) was identified in duodenal biopsies, and CMV antigenemia was detected.
Findings:
- The patient was diagnosed with CMV enteritis as a complication of steroid-induced immunosuppression.
- Treatment with ganciclovir successfully alleviated the abdominal symptoms.
Implications:
- This case underscores the risk of opportunistic infections like CMV enteritis in patients with IgA vasculitis undergoing immunosuppressive therapy.
- Close monitoring for infections and prompt antiviral treatment are crucial for managing complications in immunocompromised patients.
- Understanding the interplay between vasculitis, immunosuppression, and opportunistic infections is vital for optimizing patient care.
