 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.
