Cryptococcal meningitis in the acquired immunodeficiency syndrome.
Cryptococcosis is the most common, deep-seated fungal infection in AIDS patients, and cryptococcal meningitis is the most frequently observed syndrome. AIDS patients with cryptococcal meningitis usually have an indolent presentation and nonspecific findings on physical examination. Routine laboratory tests are of little assistance in diagnosing cryptococcal meningitis. Cerebrospinal fluid (CSF) white blood cell counts tend to be low, and glucose and protein levels are nonspecific. Serum cryptococcal antigen (CRAG) is a sensitive test for cryptococcal meningitis, and CSF CRAG is usually also positive. Definitive diagnosis is made by culture of the CSF. Therapy of cryptococcal meningitis is changing to antifungal agents that are easy to administer as outpatient therapy. Amphotericin B continues to be the primary antifungal used in initial treatment of cryptococcal meningitis; addition of flucytosine is of no benefit. Recent data suggest oral fluconazole is effective as primary therapy, and may be superior to amphotericin B as maintenance therapy. Maintenance therapy decreases the incidence of relapse and increases survival.
