Insights
Autoimmune myocarditis can cause heart failure in HIV patients. Early diagnosis via biopsy and steroid treatment can lead to full recovery of heart function.
Area of Science:
- Cardiology
- Infectious Diseases
- Immunology
Background:
- Dilated cardiomyopathy in HIV patients presents diagnostic and therapeutic challenges.
- Myocardial involvement in HIV has multiple potential causes, including autoimmune factors.
- No definitive treatment currently exists for HIV-associated cardiomyopathy.
Observation:
- A case of autoimmune myocarditis presenting as heart failure in a 39-year-old HIV-infected male.
- Endomyocardial biopsy revealed lymphocytic myocarditis with HLA-DR over-expression.
- Tests for cardiotropic viruses were negative.
Findings:
- Steroid treatment resulted in improved cardiac dimensions and function.
- Auto-reactive myocarditis is a potential cause of heart failure in HIV patients.
- Endomyocardial biopsy is crucial for diagnosing this condition.
Implications:
- Considering auto-reactive myocarditis is vital for HIV patients with dilated cardiomyopathy.
- Prompt diagnosis through biopsy and subsequent steroid therapy can resolve cardiac disease.
- This approach offers a potential treatment strategy for improving prognosis in affected individuals.
Background:
Dilated cardiomyopathy occurring in HIV-infected patients raises both diagnostic and therapeutic challenging problems. Indeed myocardial involvement in HIV infection has been variously attributed to several causes, including viral, toxic, nutritional and autoimmune, but no specific treatment capable to substantially improve patients' prognosis has been recognized so far.
Case Presentation:
Hereby we describe the case of an autoimmune myocarditis manifesting with heart failure in a3 9-year-old man with HIV infection. Left ventricular endomyocardial biopsy showed a lymphocytic myocarditis characterized by over-expression of HLA-DR and negative polymerase chain reaction for cardiotropic viruses. Steroid treatment was followed by recovery of cardiac dimension and function.
Conclusion:
Presence of auto-reactive myocarditis should be considered in patients with HIV-associated dilated cardiomyopathy. Its recognition by endomyocardial biopsy followed by steroid administration may result in a complete resolution of cardiac disease.
