Cabergoline plus metformin therapy effects on menstrual irregularity and androgen system in polycystic ovary syndrome women with hyperprolactinemia|

Background: 30% of patients with polycystic ovary syndrome (PCOS) show mild, transient hyperprolactinemia. It is suggested that a reduction of the dopamine inhibitory effect might raise both prolactin and luteinizing hormone.
Objective: To investigate the adjuvant cabergoline therapy effects on menstrual irregularity and androgen system in PCOS women with hyperprolactinemia.
Materials and Methods: This randomized clinical trial was done on 110 polycystic
ovary syndrome women with increased serum prolactin concentration [1.5 fold more
than normal level (>37.5 ng/ml)]. Participants were divided into two groups: Case
group (n=55) treated with metformin 1gr/day and cabergoline 0.5 mg/week for 4
months and control group (n=55) treated with metformin 1g/day and placebo
weekly. Testosterone, prolactin, and dehydroepiandrosterone sulfate level were
measured before and four months after intervention in two groups. Also, situation of
menstrual cycles asked and recorded before and after intervention.
Results: We found decrease in the mean of dehydroepiandrosterone sulfate, weight
and total testosterone level in the two groups after intervention but their changes
were not significant. Patients in case group showed a significant decrease in serum
prolactin level before and after intervention (p<0.001), but no difference was found
in control group. All patients in both studied groups had irregular menstrual cycles,
which regulate after intervention and the difference was significant (p=0.02).
Conclusion: The results showed that cabergoline can be used as a safe administration in PCOS patients with hyperprolactinemia to improve the menstrual cycles. Considering that the administration of cabergoline plus metformin may reduce the required duration and dose of metformin, patient acceptability of this approach is higher.
