Background: In newly diagnosed neurocysticercosis (NCC) with seizures, the choice of anti-seizure medication (ASM) seems to be arbitrary due to a lack of comparative studies. Although oxcarbazepine (OXC) is often considered efficacious for focal seizures in NCC, due to adverse effects, newer ASMs like levetiracetam (LCM) and lacosamide are also being explored.
Methods: This study was performed by case record review of children with newly diagnosed solitary viable parenchymal NCC aged 4-18years who received lacosamide and OXC at least for 12 weeks between August 2019 and April 2021, from a prospective registry of a tertiary care teaching hospital in north India. Seizure control, electroencephalographic abnormalities, resolution of inflammatory granulomas and adverse effects were compared between two arms at 12 and 24 weeks.
Results: Total 31 (8.3 ± 4.7 years, 19 boys) and 72 (8.6 ± 4.2 years, 43 boys) completed at least 12 weeks follow-up in LCM and OXC groups, out of which 2 and 51 completed at least 24 weeks follow-up in LCM and OXC groups, respectively. The occurrence of breakthrough seizure was comparable in both arms at 12 and 24 weeks (1/31 and 2/22 in lacosamide group vs. 2/72 and 4/51 in OXC group, p = 0.66 and 0.59, respectively). Patients receiving OXC had more frequent treatment-emergent adverse events (p = 0.0001) and four patients required discontinuation due to severe adverse events (SAEs), while none in the lacosamide group had SAEs.
Conclusions: Lacosamide appears to be efficacious and safe for achieving seizure freedom in patients with solitary viable parenchymal neurocysticercosis.
