STN-DBS and the Risk of Sialorrhea

Parkinson Disease Clinical Trial

Official title: STN-DBS is a Risk Factor of Sialorrhea in Patients With Advanced Parkinson's Disease

Status Completed

Clinical Trial Summary

OBJECTIVE: The aims of this study were to assess the incidence rate and risk factors for sialorrhea in the long-term follow-up in a cohort of 170 patients with advanced Parkinson's disease [84 with deep brain stimulation (DBS) and 86 on medical treatment]. Design, setting, and participants: This study was a multi-center prospective non-randomized concurrent clinical trial. A total of198 persons with Parkinson disease were referred for DBS between June 2019 and July 2021 and analyzed between June 2023 and July 2023.The primary outcome follow-up visit was conducted 36 months after DBS.

Clinical Trial Description

IMPORTANCE: Sialorrhea is a frequent and disabling symptom in patients with PD. No prospective study has been specifically designed to test the effects of DBS on sialorrhea development. OBJECTIVE: The aims of this study were to assess the incidence rate and risk factors for sialorrhea in the long-term follow-up in a cohort of 170 patients with advanced Parkinson's disease [84 with deep brain stimulation (DBS) and 86 on medical treatment]. Design, setting, and participants: This study was a multi-center prospective non-randomized concurrent clinical trial. A total of198 persons with Parkinson disease were referred for DBS between June 2019 and July 2021 and analyzed between June 2023 and July 2023.The primary outcome follow-up visit was conducted 36 months after DBS. INTERVENTIONS: Bilateral subthalamic nucleus DBS was performed in one study arm and not performed in the other. Both arms of the study completed the drooling rating scale (DRS), the drooling severity and frequency scale (DSFS) and examination of salivary secretion rate. MAIN OUTCOMES AND MEASURES: The primary outcome was the DRS scores of the patients with PD, with or without STN-DBS 36 months postoperatively. The secondary outcomes included the DSFS scores, saliva secreting rate, ratio of botox injection in different group. ;
