SO Int Conf AIDS. 1994 Aug 7-12;10(1):202 (abstract no. PB0236). Unique Identifier : AIDSLINE ICA10/94369688 AB OBJECTIVE: (1) To survey all types of adult meningitis. (2) To identify clinical and laboratory markers which distinguish types of meningitis as an aid to diagnosis in developing countries. METHODS: Blood, CSF (cerebrospinal fluid) and clinical data were collected prospectively from unselected, consecutive adults admitted to a central hospital in Zimbabwe over a 6 month period. Standard microbiology, biochemistry, HIV testing, CD4 phenotyping, and antigen testing (Cryptococcus neoformans, Pneumococcus, Meningococcus and H influenzae) were performed. RESULTS: Meningitis was demonstrated in 65 cases; 82% were HIV-positive and 80% were male. Cases were divided as follows: C neoformans 52%, Pneumococcus 23% and M tuberculosis (TB) 25%. HIV positivity rates were 100%, 53% and 88% respectively. Mean CD4 counts in HIV positive cases were 144 microliters, 116 microliters and 275 microliters respectively. Distinguishing characteristics included: (1) a CSF pleocytosis, invariable in all cases of TB and Pneumococcus, but absent in 44% of cryptococcal cases (p < 0.002), (2) neck stiffness, absent in 26% of cryptococcal, 6% of TB and 0% of pneumococcal cases (p < 0.003), and (3) confusion, rare in pneumococcal cases (7%) but common with cryptococcal cases (44%) and TB cases (56%) (p < 0.006). CONCLUSIONS: Adult meningitis was strongly associated with HIV infection. The pathogens identified reflect those seen in African AIDS. Signs of meningism, CSF inflammatory changes and India Ink staining were often absent in cryptococcal meningitis and clinical features were limited to fever and headache. An algorithmic approach to management with simple tests is possible but antigen testing would greatly assist diagnosis in equivocal cases.
