BACKGROUND
Elevated prolactin levels are associated with increased cardiometabolic risk. No previous study has compared the effect of hypolipidemic therapy on plasma levels of lipids and other cardiometabolic risk factors in patients with and without hyperprolactinemia.
METHODS
The study included three age-, weight-, blood pressure- and lipid-matched groups of premenopausal women: 18 women with untreated hyperprolactinemia, 19 women with bromocriptine-treated hyperprolactinemia and 20 drug-naïve women with normal prolactin levels. Because of concomitant atherogenic dyslipidemia, all patients were treated with fenofibrate (200 mg daily) for 12 weeks. Plasma lipids, glucose homeostasis markers, as well as plasma levels of uric acid, high-sensitivity C-reactive protein (hsCRP), homocysteine and fibrinogen were assessed at baseline and at the end of hypolipidemic treatment.
RESULTS
Unlike similar baseline lipid levels, plasma concentrations of the remaining investigated cardiometabolic risk factors were higher in women with elevated prolactin levels than in patients with normal prolactin levels. The impact of fenofibrate on total cholesterol, LDL cholesterol, HDL cholesterol and triglyceride levels, as well as on uric acid, hsCRP, homocysteine, and fibrinogen was less pronounced in women with untreated hyperprolactinemia than in women with bromocriptine-treated hyperprolactinemia and drug-naïve women with normal prolactin levels.
CONCLUSIONS
The results of our study indicate that cardiometabolic effects of fenofibrate depend on plasma prolactin levels.
