Effectiveness of intermittent diazepam prophylaxis in febrile seizures: long-term prospective controlled study

Area of Science:

• Pediatrics
• Neurology
• Clinical Pharmacology

Background:

• Febrile seizures affect young children and can recur.
• Prophylaxis aims to prevent seizure recurrence.
• Diazepam is a commonly used anticonvulsant.

Purpose of the Study:

• To evaluate the efficacy of intermittent rectal diazepam in preventing febrile seizure recurrence.
• To assess the impact of diazepam prophylaxis across different risk groups.

Main Methods:

• A prospective randomized cohort trial involving 139 children with a first febrile seizure.
• Children were divided into two groups: diazepam prophylaxis (n=68) and no prophylaxis (n=71).
• Follow-up was conducted over 3 years, with stratification into low, intermediate, and high-risk categories.

Main Results:

• The 36-month recurrence rates without prophylaxis were 46% (low-risk), 55% (intermediate-risk), and 83% (high-risk).
• With diazepam prophylaxis, recurrence rates decreased to 33% (low-risk), 35% (intermediate-risk), and 38% (high-risk).
• Diazepam significantly reduced recurrence rates in all risk strata, most notably in high-risk children.

Conclusions:

• Intermittent rectal diazepam is an effective prophylactic treatment for febrile seizure recurrence.
• The benefit is most pronounced in high-risk children when medication is administered appropriately.
• This study supports the use of diazepam prophylaxis in selected pediatric populations prone to recurrent febrile seizures.
