The objective of this study was to investigate the BDNF levels and their associations with psychopathology and lipid metabolism parameters in adolescents with MDD. From January to December 2021, the study included 141 adolescents with MDD and 90 healthy controls (HCs). The Center for Epidemiological Studies Depression Scale (CES-D), the Insomnia Severity Index Scale (ISI), the Epworth Sleepiness Scale (ESS) and the Positive and Negative Suicidal Ideation Scale (PANSI) were used to assess depressive symptoms, insomnia, excessive daytime sleepiness, and suicidal ideation, respectively. BDNF levels and lipid metabolism parameters were also measured. Compared to HCs, adolescents with MDD had significantly lower BDNF levels (p < 0.001). In patients, BDNF levels were positively correlated with age, BMI, total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C); and negatively correlated with the scores of CES-D and ISI (all p < 0.05). The results of the multivariate linear regression analyses indicated that BDNF levels were positively associated with age (β = 0.198, t = 2.447, p = 0.016), first-episode MDD (β = 0.176, t = 2.234, p = 0.027) and TC level (β = 0.240, t = 3.048, p = 0.003), and negatively associated with the scores of ESS (β = -0.171, t = -2.203, p = 0.029) and ISI (β = -0.231, t = -2.996, p = 0.003). Of note, the associations between BDNF and psychopathology were observed only in female and first-episode patients. BDNF levels were decreased in adolescents with MDD. Patients with low BDNF levels were in a more severe psychiatric state and had changes in lipid metabolism parameters.

Randomized-controlled trials (RCT) investigating first-line treatment with rTMS in comparison with first-line antidepressant medication are warranted to further position rTMS within current treatment algorithms for MDD. In this two-stage, therapy response-adapted, randomized multi-center phase 2 rater blinded trial, 106 medication-naïve patients suffering from MDD will be enrolled. In Stage I, participants receive one of the two treatment options for four weeks: either daily bilateral theta burst stimulation (TBS), a patterned and time-saving form of rTMS, or antidepressant medication with selective serotonin reuptake inhibitors (SSRI). The allocation to Stage II occurs therapy response-adapted. Therefore, patients either receive maintenance treatment or will be switched to the respective other treatment arm. Primary outcome is the comparison between the two study arms with regard to therapy response measured by the Montgomery-Asberg Depression Rating Scale (MADRS) after 4 weeks at the end of Stage I. The aim of the study is to provide reliable first evidence and effect size measures of rTMS as first-line treatment compared to SSRI treatment.
