title: [Neuromeningeal cryptococcosis in Mali].
abstract: Cryptococcal meningitis is the most common fatal central nervous system infection in AIDS patients in Sub-Saharan Africa. The purpose of this prospective study conducted from March 2003 to February 2004 in the internal medicine and infectious diseases departments of the Point G University Hospital Center was to investigate the clinical, prognostic and epidemiological profile of Cryptococcus neoformans infection in patients hospitalized for brain and meningeale infection (BMI). Diagnosis of neuromeningeal cryptococcosis (NMC) was based on positive identification of Cryptococcus by direct exam of the cebrospinal fluid (CSF) after India ink staining and/or culture on Sabouraud medium without actidione. During the study period, a total of 569 patients were hospitalized including 235 (41.3%) with HIV infection. Overall C. neoformans was identified in 14 patients. Median patient age was 39 +/- 8 years. There was a male preponderance with a sex ratio of 1.8 (9 men/5 women). Patients with BMI were HIV-positive in 85.7% of cases (n=12) and HIV-negative in 14.3% (n=2). The overall and HIV-specific prevalence of BMI was 2.5% and 5.1% respectively. The CD4 lymphocyte count was between I and 49 cells/mm3 in 64.3% of cases. The main clinical symptoms were cephalea in 85.7% of cases, altered consciousness in 50% and nausea/vomiting in 35.7%. Neurological manifestations (hemiparesis and cranial nerve deficit) were noted in 14.3%. HIV infection is the main purveyor of NMC in Mali. The actual incidence of cryptococcosis is unclear due to the poor sensitivity of diagnostic techniques. This study highlights diagnostic difficulties related to clinical polymorphism and poor technical facilities. Agglutination testing of blood and CSF is recommended, but mortality remains.
