PROGNOSIS OF TUBERCULOUS MENINGITIS - A MULTIVARIATE-ANALYSIS

Twenty-six clinical, laboratory and CT scan features in 49 patients wi th tuberculous meningitis (TBM) were analysed to identify the paramete rs of prognostic significance. Employing univariate analysis, seven va riables were found to correlate with three month outcome; these variab les included the stage of TBM on admission, focal weakness, Glasgow co ma scale (GCS), incontinence, infarction, hydrocephalus and shunt surg ery. Analysing all 26 variables, a conditional logistic regression mod el was derived. In this model stage of TBM, age, focal weakness, crani al nerve palsy and hydrocephalus were found to be contributing to the three month outcome of TBM patients as assesed by the Barthel index.
