A Combined Therapy with Myo-Inositol and D-Chiro-Inositol Improves Endocrine Parameters and Insulin Resistance in PCOS Young Overweight Women.

Introduction. We evaluated the effects of a therapy that combines myo-inositol (MI) and D-chiro-inositol (DCI) in young overweight women affected by polycystic ovary syndrome (PCOS), characterized by oligo- or anovulation and hyperandrogenism, correlated to insulin resistance. Methods. We enrolled 46 patients affected by PCOS and, randomly, we assigned them to two groups, A and B, treated, respectively, with the association of MI plus DCI, in a 40 : 1 ratio, or with placebo (folic acid) for six months. Thus, we analyzed pretreatment and posttreatment FSH, LH, 17-beta-Estradiol, Sex Hormone Binding Globulin, androstenedione, free testosterone, dehydroepiandrosterone sulphate, HOMA index, and fasting glucose and insulin. Results. We recorded a statistically significant reduction of LH, free testosterone, fasting insulin, and HOMA index only in the group treated with the combined therapy of MI plus DCI; in the same patients, we observed a statistically significant increase of 17-beta-Estradiol levels. Conclusions. The combined therapy of MI plus DCI is effective in improving endocrine and metabolic parameters in young obese PCOS affected women.

Over hypothyroidism in a woman undergoing controlled ovarian hyperstimulation.

OBJECTIVE: Thyroid function and gonadal axis are related throughout a woman's fertile period. Modifications of thyroid hormone levels have been reported as a consequence of controlled ovarian stimulation for infertility. METHODS: A 28-year-old woman with regular menses and previous evidence of euthyroidism underwent controlled ovarian hyperstimulation (COH) for assisted reproductive technology (ART). Free thyroxine (FT4), free triiodothyronine (FT3), thyroid-stimulating hormone (TSH), and autoantibodies against thyroperoxidase and thyroglobulin (TPOAb and TgAb, respectively) were measured before COH. FT4, FT3, and TSH were re-evaluated 6 days, 2 weeks (during oocyte retrieval), and 1 month after the beginning of the procedure. RESULTS: The baseline evaluation revealed subclinical autoimmune hypothyroidism. The patient was hypothyroidic at 6 days and 2 weeks and spontaneously returned to euthyroidism 1 month after COH. CONCLUSION: This is the first case of a woman with an unknown subclinical autoimmune hypothyroidism who developed overt and transient hypothyroidism as a consequence of COH. Careful thyroid evaluation is advised for women undergoing COH.
