Thyroid stimulating hormone and serum, plasma, and platelet brain-derived neurotrophic factor during a 3-month follow-up in patients with major depressive disorder.

Abstract：

BACKGROUND:Thyroid dysfunction and elevated thyroid stimulating hormone (TSH) are common in patients with depression. TSH might exert its function in the brain through blood levels of brain-derived neurotrophic factor (BDNF). BDNF decreases during depressed states and normalize after treatment. The gap is that the association between TSH and BDNF in patients with major depressive disorder (MDD) is unknown. METHODS:We studied 105 subjects ≥18 years of age with MDD and measured serum, plasma, and platelet BDNF at baseline, 1 month and 3 months during antidepressant treatment. Other baseline measurements included hypothalamic-pituitary-thyroid axis hormones such as TSH, triiodothyronine (T3) and thyroxine (T4); hypothalamic-pituitary-adrenal (HPA) axis hormones and hypothalamic-pituitary-gonadal (HPG) axis hormones and prolactin. RESULTS:Linear mixed model effect analyses revealed that baseline TSH level was negatively associated with changes of serum BDNF from baseline to 3 months (F=7.58, p=0.007) after adjusting for age, sex, and body mass index, but was not associated with plasma and platelet BDNF. In contrast, T3 and T4, HPA axis hormones, HPG axis hormones, and prolactin were not associated with serum, plasma, or platelet BDNF levels. Patients in the highest quartile of TSH showed significantly lower serum BDNF than in the other quartiles (F=4.54, p=0.038), but no significant differences were found based on T3 and T4 levels. LIMITATIONS:TSH was only measured at baseline. CONCLUSIONS:Higher TSH is associated with lower baseline and reduced the increase of serum BDNF levels during antidepressant treatment in patients with MDD.
