[Cryptococcus meningitis: clinical course, development and histopathologic aspects depending on the predisposing factors].
Seventeen consecutive cases of cryptococcal meningitis diagnosed at Hospital das Clínicas of Ribeirão Preto Medical School (São Paulo State Brazil) between 1969 and 1985 were reviewed. For analysis the patients were separated in 3 groups: I. three patients without immunodeficiency; II. six patients with associated disease: cancer (3), diabetes (2) and alcoholism (1); III. Eight renal transplant recipients that developed cryptococcosis after 18 to 67 months of immunosupression with steroids and azathioprine. The median interval between onset of symptoms and diagnosis of infection was greater in Group II (53 days) than in Groups I (25 days) or III (28 days). Neck stiffness, cranial nerve involvement and papilledema were more frequent in Group I than in Group II or III, but fever and focal neurological signs were observed only in patients of two last groups. Cerebrospinal fluid examination showed a mild lymphocytic pleocytosis in most patients, but transplant cases had polymorphonuclear cells more frequently. Late mortality was higher in patients with underlying disease and the prognosis was better for transplant patients that received effective antifungal therapy. Besides cryptococci, autopsy findings in 8 cases revealed granuloma formation in tissues, except in patients of Group II (2 cases). The differences between the groups suggest that clinical characteristics, evolution and postmortem findings of the cryptococcal meningitis are changed according to type of immunodeficiency presented by the patient.
