Study summary

To evaluate the efficacy of the prophylaxis with phenytoin in the prevention of seizures in patients with pneumococcal meningitis. Hypothesis: Administration of prophylactic phenytoin will reduce the incidence of seizures in patients with pneumococcal meningitis older than 50 yrs.

Read the detailed description

Background: Bacterial meningitis has still a high morbi-mortality despite the global improvement in therapy.

Among complications, the presence of seizures may contribute to increase the morbi-mortality. Prophylactic phenytoin is used in clinical practice in high risk patients but this use is variable because there are not controlled clinical trials demonstrating efficacy along with antibiotics and corticosteorids. Pneumococcal episodes are associated to a higher number of seizures and a higher mortality especially in elderly patients.

Objectives: To evaluate the efficacy of the prophylaxis with phenytoin in the prevention of seizures in patients with pneumococcal meningitis. Hypothesis: Administration of prophylactic phenytoin will reduce the incidence of seizures in patients with pneumococcal meningitis older than 50 yrs.

Methodology: Multicentre, randomized, double blind placebo controlled clinical trial. Patients will be included mostly from hospitals from REIPI and CAIBER and randomly assigned to receive phenytoin or placebo.

Sample size has been estimated in 61 patients per group. Antibiotic therapy and ICP prophylaxis will be standardized in all centres. Phenytoin administration will be maintained during antibiotic therapy. End point will be incidence of seizures during hospital stay and overall mortality will be a secondary end-point. Followup visits at 1 and 3 month will be performed.

Study arms

  • Experimental
    phenytoin prophylaxis

    Patients with suspected or proven pneumococcal meningitis are allocated to receive phenytoin prophylaxis or placebo to avoid seizures during the 10 days of antibiotic therapy starting after the antibiotic therapy

    Drug: Phenytoin

  • Placebo comparator
    placebo

    placebo vials and pills labeled as phenytoin prophylaxis vials and pills

    Drug: placebo

Interventions

  • DrugPhenytoin

    Phenytoin 18 mg /Kg/day iv as loading dose. 24 hours later phenytoin 6 mg/Kg/d in 3 divided doses iv shifting to oral route at the same dose when the patient is able to use oral route.

  • Drugplacebo

    Placebo 18 mg /Kg/day iv as loading dose. 24 hours later placebo 6 mg/Kg/d in 3 divided doses iv shifting to oral route at the same dose when the patient is able to use oral route.
