Short course of prednisolone in Indian patients with solitary cysticercus granuloma and new-onset seizures

Abstract

Purpose: To evaluate the role of a short course of oral corticosteroids in Indian patients with solitary cysticercus granuloma with seizures.

Methods: In this open-label, randomized, prospective follow-up study, 97 patients with new-onset seizures and a single enhancing computed tomography (CT)-detected lesion of cysticercosis were randomly divided in two groups to receive either antiepileptic monotherapy alone (n = 48) or antiepileptic monotherapy with prednisolone (n = 49). The patients in the latter group received prednisolone, 1 mg/kg/day for 10 days, followed by tapering over next 4 days. The patients were followed up for 6 months. Repeated CT scans were performed after 1 and 6 months.

Results: The majority of patients were young. Simple partial seizure, with or without secondary generalization, was the commonest seizure type encountered. Follow-up CT scans at 1 and 6 months demonstrated a significantly better response for prednisolone as far as complete resolution of CT lesion was concerned. Kaplan-Meier analysis suggested significantly less probability of seizure recurrence for prednisolone-treated patients. At 6 months, Kaplan-Meier estimated risk of seizure after first seizure was 2% in prednisolone-treated patients in comparison to 13% for those who were not given prednisolone.

Conclusions: Short-term prednisolone therapy helps in rapid resolution of solitary cysticercus granuloma in Indian patients with new-onset seizures. Resolution of lesions is associated with improved seizure-related prognosis.
