    Abstract:
    SETTING: The patients admitted to the Neurology ward of the All India Institute of Medical Sciences Hospital. OBJECTIVE: To assess the role of dexamethasone as an adjunct to antimicrobial therapy in the treatment of tuberculous meningitis. DESIGN: A randomised controlled trial of 47 patients was conducted over a 13-month period. 41 patients completed the trial. Patients were stratified into mild, moderate and severe groups and randomly allocated to steroid and non-steroid groups. All patients received a standardized antituberculosis drug regime. The end point was 3 months, or death if earlier. The evaluation at the end point included survival, resolution of symptoms, sequelae and activities of daily living. Results were analysed using the Wilcoxon rank sum test. RESULTS: The patients in the dexamethasone group fared better. 75% of this group had mild sequelae as opposed to 62% of the control group. Amongst the survivors, those who received dexamethasone sensorium improved earlier, and there was greater improvement in mental function and daily activities. The difference, however, did not reach statistical significance. CONCLUSIONS: Dexamethasone appears useful as an adjunct in the treatment of tuberculous meningitis especially in patients who have severe disease. The results need confirmation by a larger trial.
