ABSTRACT: It has been hypothesized that hyperprolactinemia may contribute to the pathogenesis of multiple sclerosis (MS). In a case-control study, 58 patients with definite relapsing-remitting MS (RRMS) during relapse and 58 sex-matched and age-matched healthy controls were assessed for serum prolactin (PRL) concentration. Mean serum PRL levels (± standard deviation) were significantly higher in patients with MS (501.3 ± 232.6 mIU/L) than in healthy control patients (233.3 ± 142.7 mIU/L; p < 0.0001). Furthermore, these differences were consistent in each sex: females with MS (704.4 ± 119.6 mIU/L) compared to female controls (305.5 ± 156.9 mIU/L p < 0.001); and in males with MS (358.0 ± 180.0 mIU/L) compared to male controls (182.3 ± 107.5 mIU/L; p < 0.001). Our findings provided more evidence to support the hypothesis that patients with RRMS, regardless of gender, are in a hyperprolactinemic state.
