Effect of methyl prednisolone on sensory motor functions in tuberculous meningitis.
A prospective hospital based study was undertaken to study the effect of methyl prednisolone therapy on sensory and motor functions in tuberculous meningitis (TBM). The patients with TB meningitis seen during 1994-1998 were studied. CT scan, motor evoked potential (MEP) to upper and lower limbs; and median and tibial somatosensory evoked potentials (SEP) were carried out in all the patients. Outcome was defined at the end of 3 months into poor, partial or complete recovery on the basis of Barthel index score. Inj methyl prednisolone (MPS) 500 mg IV was given to 21 patients followed by oral tapering dose of prednisolone over one month in addition to 4 drug anti-tubercular treatment. The control group comprised of 16 patients who received 4 drugs anti-tubercular therapy without any corticosteroid. These groups were comparable with respect to their age, stage of meningitis, Glasgow coma scale score and radiological findings. In MPS group, CMCT was abnormal in 9 and SEPs in 7 patients. In the control group, these were abnormal in 9 and 5 patients respectively. Three months after the therapy the frequency of improvement, deterioration and stationary evoked potential (EP) changes were also noted in both the groups. Diversity of evoked potential changes were also noted. Evoked potential changes were neither significantly different between the groups nor there was any beneficial effect shown in MPS group at 3 months. On the contrary, the control group fared significantly better than the MPS group. Initial MEP and SEP abnormalities were however related to 3 months outcome (p<0.01).
