[Successful discontinuation of antifungal secondary prophylaxis in AIDS-related cryptococcosis].

The clinical and laboratory data of 22 patients with AIDS related cryptococcosis who were able to interrupt antifungal secondary prophylaxis after HAART administration, are presented. They were 14 males and 8 females, between 15 and 50 years old (X: 34 years old). All patients presented fever and severe deterioration of their general health status, and 19 exhibited a meningeal syndrome. At the start of antifungal treatment, 59% of the cases presented < 50 CD4+ cells/microl, the median viral burden was 134,804 RNA copies/ml and the median titer of serum cryptococcal antigen was 1/3,000. Amphotericin B by intravenous route, (0.7 mg/kg/day) or fluconazole (600 to 800 mg/day) were given as a treatment of the initial episode, up to CSF cultures negativization. Oral fluconazole (200 mg/day) or intravenous amphotericin B, 50 mg twice a week, were given as a secondary prophylaxis. The secondary prophylaxis was interrupted when the patients had received HAART for an average lapse of 19 months (6 to 36 months) and the median CD4+ cell count was 249/microl. The follow up after secondary prophylaxis discontinuation lasted for a median lapse of 22 months. These data seem to show that secondary prophylaxis is not necessary when the patient are clinically asymptomatic and the CD4+ cell counts are above 150/microl.
