Abstract:
Two cases of Histoplasma meningitis are presented, illustrating the difficulty in diagnosis and treatment. The first case occurred in a patient with acquired immunodeficiency syndrome as a relapse of disseminated histoplasmosis and resolved after prolonged treatment and ongoing antiretroviral therapy. The second case occurred in a cardiac allograft recipient as meningitis and focal brain lesions that responded to liposomal amphotericin B, but the patient died shortly after therapy was completed. Unfortunately, there are no prospective studies addressing the diagnosis and management of patients with histoplasmosis of the central nervous system from which to provide evidence-based guidelines for care. In the absence of such data, an approach will be presented on the basis of our experience and opinions.
Insights
Diagnosing and treating Histoplasma meningitis is challenging, especially in immunocompromised patients. This study presents two cases highlighting difficulties and proposes an approach based on clinical experience due to a lack of evidence-based guidelines.
Area of Science:
- Mycology
- Infectious Diseases
- Neurology
Background:
- Histoplasma meningitis is a rare but serious fungal infection affecting the central nervous system.
- Diagnosis and management are challenging, particularly in immunocompromised individuals.
Observation:
- Two cases are presented: one in an acquired immunodeficiency syndrome patient with relapsed disseminated histoplasmosis, and another in a cardiac allograft recipient with meningitis and brain lesions.
- The first patient achieved resolution with prolonged treatment and antiretroviral therapy.
- The second patient showed initial response to liposomal amphotericin B but ultimately succumbed to the infection.
Findings:
- The cases illustrate significant diagnostic and therapeutic challenges in Histoplasma meningitis.
- There is a critical lack of prospective studies to establish evidence-based guidelines for managing central nervous system histoplasmosis.
Implications:
- Clinical experience and expert opinion are crucial for guiding the management of Histoplasma meningitis in the absence of robust data.
- Further research is needed to develop standardized diagnostic and treatment protocols for this severe opportunistic infection.
