Effect of sertraline on depression severity and prolactin levels in women with polycystic ovary syndrome: a placebo-controlled randomized trial.

Abstract

There is a paucity of data regarding the safety and efficacy of antidepressant therapy in women with polycystic ovary syndrome and depression. The effect of antidepressant medications on circulating prolactin levels is of concern in this patient population. We aimed to evaluate the effect of sertraline on depression severity and serum prolactin levels in women with polycystic ovary syndrome and mild-to-moderate depression. In a parallel-design, two-center, randomized controlled trial, we stratified participants according to their baseline prolactin level into normal (<25 ng/mL) and high (≥25 ng/mL) prolactin groups. Each group was randomized to receive 50 mg daily sertraline (up-titrated after 25 mg daily for 1 week) or placebo. The enrolling physicians, outcome assessors, and study subjects were all blind to the treatment. Depression severity was assessed by the Hamilton depression rating scale at baseline, the third, and the sixth weeks. The primary efficacy outcome was a change in depression severity. Prolactin levels were checked at baseline and after 6 weeks, and the safety outcome was the alteration in prolactin levels. Overall, 513 women were screened for eligibility in two outpatient clinics. Ultimately, 74 (38 normal prolactin and 36 high prolactin level) individuals were randomized. After 6 weeks of follow-up, depression severity was significantly reduced among patients who received sertraline regardless of the baseline prolactin levels (all between subjects P < 0.001). Furthermore, there was no difference in prolactin levels between the sertraline and placebo arms in normal (P = 0.80) or high prolactin (P = 0.21) groups. Sertraline is a well-tolerated and effective choice for treating depression in women with polycystic ovary syndrome. Future studies with longer follow-up periods are required to draw more robust conclusions.
