    Abstract:
    The results of the studies of hypophyseal-gonadal axis in dialysis women are not uniform. Mostly the increased serum concentrations of prolactine and pituitary gonadotropins are observed; the data about ovarian secretion are much more scanty and contradictory. The aim of this crossectional study was to assess changes in sexual hormones secretion and their associations with menstrual disturbations in premenopausal women with end-stage renal failure undergoing hemodialysis. Sixty three women from six mazovian dialysis units, aged 18-45 years (mean 35 +/- 7 years) were enrolled into the study. They were divided into four groups according to their menstrual pattern: I--eumenorrhoea (n = 17), II--polymenorrhoea (n = 9), III--oligomenorrhoea (n = 16) i IV--amenorrhoea n = 21). There were no differences between both groups in respect to age, age of menarche, time on hemodialysis, and body mass index. In all subjects gynecological examination was performed and serum prolactin, FSH, LH, estradiol, progesterone and testosterone concentrations were assayed. In 49% women high serum prolactin concentrations were noted (the highest in group IV--1699 +/- 1022 vs 441 +/- 205 microIU/ml in group I; p < 0.05). Mean serum FSH and LH were increased in group IV only (33 +/- 59 and 22 +/- 31 mIU/ml); no significant differences among groups examined were seen. Serum estradiol was increased in groups I-III (95 +/- 46, 72 +/- 33, and 83 +/- 55 pg/ml, respectively) and decreased in group IV (27 +/- 22 pg/ml; p < 0.001 in respect to remaining groups). Mean serum progesterone and testosterone concentrations were normal in all four groups, but serum progesterone was significantly lower in groups II-IV than in group I (p < 0.05). No differences in hormonal status between patients receiving and not receiving rHuEpo were observed. Menstrual disturbances are common (73%) in premenopausal women with end-stage renal failure, with amenorrhea constituting a half of them. Hyperprolactinemia is the most frequently seen alteration in their hormonal profile with the highest concentrations in those with secondary amenorrhea. Increased serum gonadotropins and reduced serum estradiol concentrations are mostly seen in amenorrheic women, whereas in menstruating women serum estradiol is often slightly increased.
