Relationship between thyroid-stimulating hormone and blood lipids in patients with first-episode depression – BMC Psychiatry
Background Previous studies demonstrated thyroid stimulating hormone (TSH) plays an important role in regulating lipid metabolism, but the relationship between the two is controversial. Meanwhile, it has not been reported in a population with major depressive disorder (MDD). Methods We divided 1718 first-episode and drug naïve patients with MDD into a TSH abnormal group (TSH-AB) and a TSH normal group (TSH-NOR).
