Abstract

Cryptococcal meningitis (CM) is associated with raised intracranial pressure which is linked with serious neurological sequelae. Cryptococcus neoformans produces D-mannitol in vitro and in experimental meningitis in rabbits. Mannitol present in the cerebrospinal fluid (CSF) of CM patients could exacerbate raised intracranial pressure and contribute to neurological damage. To link CSF mannitol to cryptococcal infection, levels of mannitol in the CSF of AIDS patients with CM were measured by gas-liquid chromatography. Mannitol was detected in 19 of 21 samples (range, 1.5 to 26.2 nig/liter), but there was no quantitative correlation between the mannitol concentration and the cryptococcal antigen titer.
