[Successful discontinuation of antifungal secondary prophylaxis in AIDS-related cryptococcosis]. / Interrupción exitosa de la profilaxis secundaria antifúngica en la criptococosis asociada al SIDA.

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.

Se presentan los datos clínicos de 22 pacientes con criptococosis asociada al VIH que interrumpieron la profilaxis antifúngica secundaria, después de haber recibido la terapéutica antirretroviral de gran actividad (TARGA). Fueron 14 varones y 8 mujeres con edades comprendidas entre los 15 y los 50 años (X: 34 años). Todos presentaron un síndrome infeccioso general grave y 19 tuvieron meningoencefalitis. En el momento del diagnóstico 59% de los enfermos tenía recuentos de células CD4+ < 50/µL,la mediana de lascargas viralesfue de 134. 804 copias ARN/ml yla mediana de los títulosde antigenemiafue de 1/3.000. El tratamiento del episodio agudo se realizó con anfotericina B por vía venosa (0,7 mg/kg/día) o fluconazol(600 a 800 mg/día), hasta la negativización de los cultivos de LCR. La profilaxis secundaria consistió en la administración oral de 200 mg diarios de fluconazoló 2 dosis semanalesde 50 mg de anfotericina B. La profilaxis secundaria antifúngica fue interrumpida cuando los enfermos habían recibido la TARGA por un lapso medio 19 meses, la mediana de los recuentos de células CD4+ fue de 249/µl. Todos estaban asintomáticos y en buen esta-do general. El lapso medio de seguimiento posterior fue de 22 meses y ningún enfermo experimentó recidivas desu micosis.
