Corticosteroids to Reduce Frequency of Seizures in Neurocysticercosis Patients
Treatment of Intraparenchymal Neurocysticercosis: Effect of Increased Dosing of Corticosteroids on Seizure Frequency
The purpose of this study is to determine whether a short course of increased corticosteroid dosing with tapered dosing decreases seizure frequency as compared to standard corticosteroid dosing in patients with neurocysticercosis (NCC).

NCC is the most common parasitic infection of the central nervous system (CNS). It is caused by ingestion of eggs from a tapeworm of genus Taenia. Inflammation, seizures, or neurologic problems may occur in a patient with NCC. Corticosteroids are the current standard of care for NCC patients, but corticosteroids have many side effects. Albendazole is used to treat infections caused by worms; however, it is unclear if its use with the corticosteroid dexamethasone will decrease seizure frequency in NCC patients. The purpose of this study is to evaluate the efficacy of reducing seizure frequency with a short course of dexamethasone with tapered dosing when given with albendazole, as compared to standard dexamethasone and albendazole treatment, in NCC patients.

In this open label study, patients will be randomly assigned to one of two arms. Group I will receive 6 mg dexamethasone daily for 10 days only. Group II will receive 6 mg dexamethasone daily for 10 days, then 8 mg dexamethasone daily for 4 weeks with a 2-week taper. Both groups will also receive albendazole and omeprazole (a medicine that helps prevent gastroesophageal disease [GERD], a side effect of corticosteroid use). There will be 13 study visits over a 360-day period. Blood collection will occur at most visits. Group II will also undergo sputum smears and rapid culture testing on Days 14, 28, and 42. Patients will undergo magnetic resonance imaging (MRI) at screening and on Day 180 and computed tomography (CT) scanning on Day 360.

Inclusion Criteria:

  • Diagnosed with intraparenchymal NCC with 20 or fewer active cysts, as confirmed by enzyme-linked immunoelectrotransfer blot (EITB)

Exclusion Criteria:

  • Primary generalized seizures not caused by NCC
  • Subarachnoid or ventricular NCC
  • Any vesicular lesion greater than 2 cm in diameter

  • History of TB in the patient or history of TB in close contact of patient
  • Chest x-ray suggestive of past or current TB
  • Diabetes
  • Systemic conditions (e.g., chronic kidney failure, liver disease, heart failure, steroid-dependent immune diseases) other than NCC that may interfere with the study
  • Predicted survival time of less than 1 year
  • Inability to undergo CT or MRI
  • Hypersensitivity to albendazole, antiepileptic drugs, or contrast
  • Hypertension at rest
  • Require corticosteroids, received corticosteroids in the 4 weeks prior to study entry, or received corticosteroids for 9 or more days within the 6 months prior to study entry
  • Other CNS processes that may interfere with study assessments
  • Pregnancy or breastfeeding
