Among 31 adult patients identified as having definite or probable tuberculous meningitis,a majority(n=20[65%])were infected with HIV. Cumulative rates of occurrence per 100,000 persons over the 12 years of the study were estimated at 1.72 for those without HIV infection and 400 for those with HIV infection.The most common symptoms at presentation were fever(83%[24/29])and abnormal mental status(71%[20/28]).One or more abnormalities were present in the cerebrospinal fluid of 97%(30/31)of subjects and 74%(23/31)had cerebrospinal fluid cultures positive for Mycobacterium tuberculosis.Neuroimaging of 28 patients revealed 1 or more abnormalities in 82%(n=23).Among 30 patients with available outcome data at 9 months,43%(n=13)had died,40%(n=12)had survived without sequelae,and 17%(n=5)had survived with morbidity.HIV infection had no discernible effect on findings.Tuberculous meningitis remains relatively common among indigent urban nonwhite populations.While HIV infection has contributed to the increased incidence of tuberculous meningitis,it has not significantly altered the presenting clinical,laboratory,or radiographic findings or the response to therapy of this disease.Parameters associated in a multivariate regression analysis with mortality at 9 months were black race and the absence of corticosteroid use. |
