October 25, 2023 updated by: Hatem Samir Shehata, Cairo University

Long-term Follow-up of Safety and Efficacy of OnabotulinumtoxinA for Treatment of Sialorrhea in Juvenile Cerebral Palsy

A 100 units of botulinum toxin was injected in both parotid and submandibular glands for children (2 - 12 years) with incapacitating sialorrhea in juvenile cerebral palsy patients and they are followed up for 1 year

Detailed Description

This was a prospective, longitudinal analysis with 1-year follow-up of 52 children with juvenile cerebral palsy (JCP) suffering from sialorrhea enrolled from 3 tertiary pediatric neurology rehabilitation centers (two in Cairo and one in Alexandria) and subjected to repeated BoNT-A injection.

The recruitment period was between June 30, 2021, until May 1, 2022 (the last patient follow-up ended on April 30, 2023).

Intervention: 100 units of OnabotulinumtoxinA (Botox®) were injected in the parotid and submandibular glands Follow-up visits: mo 1 post-injection (for every injection session) and every 3 months thereafter

In each visit; the following efficacy variables were assessed:

Primary outcome measures: The severity and frequency of sialorrhea evaluated by Drooling Severity Scale (DSS), and Drooling Frequency Scale (DFS) and visual-analogic ratings of familial distress (VAS-FD).

Secondary outcome measure: The carers' Global Impression of Change Scale score measured on a 7-point Likert scale from -3 (very much worse) to +3 (very much improved)

Also, adverse events were assessed in each visit

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Drooling Severity Scale (DSS) and the Drooling Frequency Scale (DFS)
Time Frame: 1 year
Each patient was assigned a severity rank according to the following grades: 1, dry: never drools; 2, mild: only the lips are wet; 3, moderate: wet on the lips and chin; 4, severe: drools to the extent that clothing becomes damp; 5, profuse: clothing, hands, tray, and objects become wet. The frequency of drooling was also rated as 1, never drools; 2, occasional drooling; 3, frequent drooling; and 4, constant drooling. The final drooling score is the summed ranking across both scales together to make a combined drooling ranking from 2 to 9.
