Fungal Burden, Early Fungicidal Activity, and Outcome in Cryptococcal Meningitis in Antiretroviral-Naive or Antiretroviral-Experienced Patients Treated with Amphotericin B or Fluconazole

In a prospective observational study of 54 patients with human immunodeficiency virus-associated cryptococcal meningitis, the early fungicidal activity of amphotericin B (1 mg/kg/day) was significantly greater than that of fluconazole (400 mg/day). Compared with antiretroviral therapy-naive patients, patients developing cryptococcal meningitis while already receiving antiretroviral therapy had lower baseline fungal burdens and a longer median duration of survival, but there were no differences observed in fungal clearance, cerebrospinal fluid proinflammatory cytokines, or 10-week mortality.
