[Interrelationship of abnormal family history in the first degree relatives and clinical phenotype of patients with polycystic ovary syndrome]

Abstract

Objective: To study the relationship of abnormal family history in the first degree relatives and the clinical phenotype of patients with polycystic ovary syndrome (PCOS).

Methods: Clinical data of first degree relatives of 139 women with PCOS were collected by questionnaires, including body mass index (BMI), waist hip ratio (WHR), and hursutism score. Follicle stimulating hormone (FSH), luteinizing hormone (LH), prolactin (PRL), testosterone (T), androstenedione (A), oral glucose tolerance test (OGTT) and insulin releasing test were measured.

Results: (1) Compared with patients with a negative family history of diabetes mellitus, for women with a positive family history, WHR (0.99 +/- 0.10 vs 0.79 +/- 0.08) and score of hirsutism (1.9 +/- 1.2 vs 1.8 +/- 1.2) were increased, the duration of menstruation was longer [(108 +/- 10) vs (92 +/- 19) days]; A [(11 +/- 6) vs (8 +/- 5) nmol/L], homeostasis model assessment of insulin resistance (HOMA-IR, 3.5 +/- 2.0 vs 2.7 +/- 1.6), area under curve (AUC) glucose [(836 +/- 245) vs (748 +/- 139) nmol.L(-1).min(-1)], AUC insulin [(9670 +/- 4582) vs (7330 +/- 4311) mIU.L(-1).min(-1)], fasting glucose [(5.0 +/- 1.1) vs (4.8 +/- 0.5) mmol/L] and fasting insulin [(15 +/- 8) vs (11 +/- 8) mIU/L] were increased, while early insulin secretion function index (DeltaI60/DeltaG60, 32 +/- 22 vs 52 +/- 30), insulin sensitive index (ISI, 0.019 +/- 0.011 vs 0.033 +/- 0.014) and disposition index (DI, 18 +/- 10 vs 30 +/- 22; P < 0.05) were decreased. (2) For women with a positive family history of menstrual disorder, WHR and score of hirsutism (0.99 +/- 0.09 vs 0.80 +/- 0.10 and 1.9 +/- 1.0 vs 1.6 +/- 1.1) were increased respectively, the duration of menstruation [(105 +/- 28) vs (84 +/- 31) days] was longer, HOMA-IR (3.6 +/- 2.4 vs 2.5 +/- 1.7) and fasting insulin level [(15 +/- 14) vs (12 +/- 11) mIU/L] were increased, while HOMA-beta (178 +/- 134 vs 207 +/- 175), ISI (0.017 +/- 0.009 vs 0.033 +/- 0.012) and DI (23 +/- 18 vs 28 +/- 19, P < 0.05) were decreased. (3) For women with a positive family history of premature balding, BMI and the score of hirsutism [(26 +/- 4) vs (23 +/- 5) kg/m(2) and 2.1 +/- 1.1 vs 1.7 +/- 1.3] were increased respectively, while DI (20 +/- 11 vs 30 +/- 23, P < 0.05) was decreased. (4) DeltaI60/DeltaG60 (34 +/- 27 vs 50 +/- 30) was decreased and fasting insulin [FINS, (13 +/- 10) vs (10 +/- 9) mIU/L] was increased in PCOS women with a family history of hypertension (P < 0.05). (5) For women with or without a family history of coronary heart disease, they did not have any difference in every parameter mentioned before.

Conclusions: The family history of diabetes mellitus has the most effect on the clinical phenotype in women with PCOS. The family history of other diseases such as menstrual disorder, premature balding and hypertension play less significant roles. A family history of positive coronary heart disease does not affect the clinical phenotype of such patients.
