Official title
A Study on the Efficacy and Safety of Sertraline Combined With Multi-Strain Probiotics in Treating Adolescent Patients With Depression: A Multi-Center Randomized Controlled Clinical Trial
Overview
The objective of this clinical trial is to evaluate the efficacy and safety of sertraline combined with multi-strain probiotics in adolescents aged 12-18 with major depressive disorder. The primary research question is whether sertraline combined with multi-strain probiotics is superior to sertraline combined with placebo in alleviating depressive symptoms and improving mood symptoms in adolescents. If there is a control group: researchers will compare sertraline combined with multi-strain probiotics with sertraline combined with placebo (a substance that looks similar but does not contain probiotics) to determine whether adding multi-strain probiotics provides greater therapeutic benefits for adolescent patients with depression. Participants will: 1. Undergo 8 weeks of treatment with sertraline combined with multi-strain probiotics or sertraline combined with placebo; 2. Have clinical visits every 4 weeks for clinical assessments and safety monitoring.
Interventions
- Drug Sertraline
Weeks 1-4, the starting dose of sertraline is 25 mg/day, adjusted according to the clinical assessment of the psychiatrist, with a dosage range of 25-150 mg/day. By week 4, the sertraline dosage should reach at least 150 mg/day; placebo powder, 1 sachet/day.
Primary outcome measures
- Change in Children's Depression Rating Scale - Revised (CDRS-R) scores [Time frame: Assessments will be performed at baseline, week 4, and week 8]
Secondary outcome measures (1)
- Change in Baker Depression Scale#BDI# scores from baseline [Time frame: Assessments will be performed at baseline, week 4, and week 8]
