title: Oral fluconazole as suppressive therapy of disseminated cryptococcosis in patients with acquired immunodeficiency syndrome.
abstract: OBJECTIVE
  Because of the increasing numbers of patients with acquired immunodeficiency syndrome (AIDS) who will require treatment for cryptococcosis and because of the problems associated with long-term administration of intravenous amphotericin B, an alternative therapeutic approach in the form of an efficacious and easily administered oral antifungal drug would be of great benefit. Fluconazole, a new triazole antifungal agent, represents such an alternative. We therefore conducted an open, non-randomized trial of oral fluconazole as maintenance suppressive therapy of disseminated cryptococcosis in patients with AIDS.
  
  
  METHODS
  Twenty patients with AIDS, 19 of whom had cryptococcal meningitis, were studied. Patients were followed for up to 21 months. All patients received amphotericin B as primary therapy, from 20 to 257 days prior to entry (500 to 5,080 mg total dose). Eight also received flucytosine. After administration of amphotericin B for acute disseminated cryptococcosis, and prior to initiation of fluconazole therapy, Cryptococcus neoformans was isolated from the cerebrospinal fluid (CSF) in two patients and from the blood in one patient. Fluconazole was given once daily, in doses of 50 to 200 mg/day.
  
  
  RESULTS
  Following initiation of fluconazole, results of CSF and blood cultures continued to be negative, except for the CSF culture in one patient who had a relapse in the 32nd week of therapy. Fluconazole therapy has been successfully continued in nine patients, for a median of 11 months (nine to 21 months). Seven patients died; five had no evidence of active cryptococcosis at the time of death. Two patients had a relapse, although the CSF culture showed growth of the fungus in only one patient. One patient was lost to follow-up after five months of therapy and one was unevaluable. Fluconazole had to be discontinued in only one patient in whom thrombocytopenia developed, and then resolved when the drug was stopped.
  
  
  CONCLUSIONS
  We conclude that oral fluconazole represents a significant advance in the management of cryptococcal meningitis and should be useful in the long-term suppressive therapy of this opportunistic infection in patients with AIDS.
