Oral contraceptives alone and with spironolactone increase sCD40 ligand in PCOS patients

Background: The present study was designed to determine the effect of oral contraceptives (OCP) and OCP plus spironolactone (Sp) on plasma soluble CD40L levels in polycystic ovary syndrome (PCOS) patients. Methods: Fifty-six women with PCOS were randomized into two treatment protocols: Ethinylestradiol + cyproterone acetate (2 mg, EE/CA; n = 28), and EE/CA with spironolactone (Sp; n = 28). Plasma sCD40L levels were measured before and after a 3-month treatment. Results: Before the initiation of treatment, the sCD40L levels were not significantly different between the groups [EE/CA (1.33 ng/mL) vs. EE/CA + Sp (1.23 ng/mL); P > 0.05]. In the post-treatment period, sCD40L concentrations were increased compared with pre-treatment values in the EE/CA and EE/CA + Sp groups (1.33 vs. 2.70 ng/mL, P = 0.011; and 1.23 vs. 2.41 ng/mL, P = 0.017; respectively). Conclusion: Increased plasma concentrations of sCD40L are associated with OCP and OCP + Sp treatment regimens in PCOS patients.
