What is the typical induction therapy regimen for cryptococcal meningitis in HIV infection?

• A. Amphotericin B (liposomal) plus flucytosine for at least 2 weeks, followed by fluconazole
• B. Fluconazole monotherapy
• C. Voriconazole with flucytosine
• D. Amphotericin B deoxycholate alone

Answer: (A)

Induction therapy for cryptococcal meningitis in HIV infection aims to rapidly clear the fungus from the CSF by using two drugs with strong activity together. The best approach is to use amphotericin B in its liposomal form plus flucytosine for about two weeks. The liposomal version is preferred because it delivers the potent antifungal effect while reducing kidney toxicity. The combination works synergistically to quickly lower fungal burden, which improves survival and helps control the infection fast. After this induction phase, treatment moves to fluconazole for consolidation and then maintenance therapy to prevent relapse, especially in the setting of ongoing immunosuppression. Fluconazole alone isn’t sufficient for induction because it inhibits growth more slowly and doesn’t sterilize CSF quickly enough. Voriconazole with flucytosine isn’t the standard induction regimen for cryptococcal meningitis. Amphotericin B deoxycholate alone is less effective and more toxic without the companion drug, making it a poorer choice for induction.
