[Comprehensive approach to clinical background and effect of bromocriptine administration in patients with endocrinological polycystic ovarian disease].

Present study was performed to elucidate the clinical features and the treatment of so-called endocrinological polycystic ovarian disease (PCO). 36 cases out of 189 infertile patients who had various ovulatory disturbances were subjected during past four years. They were selected by the definitions as follows; 1) serum LH levels greater than or equal to 30 mIU/ml and serum FSH levels less than or equal to 15 mIU/ml, 2) hyper-response of LH secretion by LH-RH (100 micrograms) loading test; maximum values greater than or equal to 250 mIU/ml. Serum androstenedione (ASD), dehydroepiandrosterone-sulfate (DHA-S), estrone (E1), estradiol (E2), progesterone (P, in the mid-luteal phase) and testosterone (T) levels were examined by RIA method for the purpose of the evaluation of the endocrinological background of the PCO in Japanese women. The same examinations were also done in 8 volunteer women who had normal ovulatory menstrual cycles for the control study. In 6 cases of the PCO patients who showed biphasic BBT charts, the endometrial biopsy was done in the mid-luteal phase at the same time of the blood sampling. And the correlation between various serum hormone levels and the endometrial morphology in the PCO patients was also discussed. Then bromocriptine (5 mg/day) was administered in these patients for more than 30 days and the effect of the treatment was investigated. Serum ASD levels in the PCO patients were significantly higher than those in the control (2.52 +/- 1.30 vs. 1.43 +/- 1.21 ng/ml, M +/- S.D., p less than 0.05), while serum E2 and P levels in the patients were significantly lower than those in the control (E2: 118.6 +/- 39.5 vs. 192.5 +/- 53.9 pg/ml, p less than 0.005. P: 7.26 +/- 5.08 vs. 124.4 +/- 4.6 ng/ml, p less than 0.005, respectively). There were no significant differences in serum levels of the other hormones. By the administration of bromocriptine, serum ASD levels decreased (1.62 +/- 1.34 ng/ml, p less than 0.05), and E2 (177.9 +/- 48.6 pg/ml, p less than 0.025) and P (11.8 +/- 4.3 ng/ml, p less than 0.005) levels increased significantly into the levels of control. Serum LH levels of the patients were also suppressed by the treatment of bromocriptine (42.5 +/- 13.7 vs. 27.4 +/- 12.0 mIU/ml, p less than 0.005), however there was no change in serum FSH levels.(ABSTRACT TRUNCATED AT 400 WORDS)
