Effectiveness and Safety of Nitrazepam in Children with Resistant West Syndrome.

Abstract

OBJECTIVES:

To study the effectiveness, tolerability, and safety of oral nitrazepam in children with resistant West syndrome (WS).

METHODS:

This prospective observational study was conducted at a tertiary care hospital in North India from January 2019 to October 2020. Children with WS resistant to standard therapy were enrolled within 7 d of initiation of nitrazepam and prospectively followed-up for cessation of spasms and adverse events.

RESULTS:

Forty-one children with resistant WS initiated on nitrazepam therapy were evaluated. The median age at onset of spasms was 6 mo (Q1, Q3: 4, 8). There was a preponderance of male gender (71%) and structural causes (78%). More than half of the enrolled children had failed four or more antiseizure medications (ASM) for epileptic spasms. The study participants had a long lead-time-to-treatment (LTTT) for the initial standard therapy (median: 2 mo; Q1, Q3: 1, 5) and nitrazepam (median: 11 mo; Q1, Q3: 8, 16). Nitrazepam was instituted as monotherapy in 7 (17%) children and as an adjunct in the rest. Twenty-one (51%) children achieved persistent cessation of epileptic spasms. However, the electroclinical response was observed in 17 (42%) children. Drowsiness, sialorrhea, and decreased appetite were the most commonly observed adverse events. Most adverse events were mild to moderate in severity and did not require dose reduction or change of medication. There was no significant difference between the responders and nonresponders in terms of LTTT, age at onset, or etiology.

CONCLUSIONS:

Nitrazepam is a safe and feasible treatment alternative in children with resistant WS resulting in persistent cessation of spasms and electroclinical response in nearly half of patients.
