title: Methotrexate as a corticosteroid-sparing agent in complicated neurocysticercosis.
abstract: BACKGROUND
  A subset of patients with neurocysticercosis developed chronic or recurrent perilesional inflammation and required long-term and high-dose corticosteroid therapy. Such therapy frequently results in severe adverse effects. The purpose of this study was to determine whether methotrexate can be used as an effective corticosteroid-sparing or replacement agent in patients with complicated neurocysticercosis.
  
  
  METHODS
  This study was a nonblinded, prospective, observational trial. Patients with neurocysticercosis who required prednisone (15 mg/day) or its equivalent for > or =2 months, were likely to require long-term corticosteroid therapy by nature of their disease, developed serious complications due to corticosteroid use, or presented with a long-term history of corticosteroid use and had continued evidence of ongoing inflammation were eligible for methotrexate treatment.
  
  
  RESULTS
  Four patients are described in this study: 2 with subarachnoid neurocysticercosis, 1 with severe intraventricular and parenchymal disease, and 1 with recurrent perilesional edema around calcified lesions. Chronic inflammation due to neurocysticercosis resulted in lacunar infarcts, visual impairment, hydrocephalus, and seizures in these patients and necessitated long-term treatment with corticosteroids, which resulted in multiple adverse effects. The addition of methotrexate, prescribed at < or =20 mg/week, allowed for the successful reduction of corticosteroid use in all 4 patients and resulted in the improvement of many corticosteroid-associated adverse effects.
  
  
  CONCLUSIONS
  Methotrexate is a beneficial corticosteroid-sparing or replacement agent for patients with neurocysticercosis who develop chronic or recurrent perilesional inflammation.
