The results of the study might suggest that ADAMTS and IL molecules have a role in the pathogenesis of the PCOS. Further efforts are needed to establish causality for ADAMTS-IL axis.

Hyperinsulinemia and insulin resistance are commonly seen in patients with hirsutism and polycystic ovary syndrome (PCOS), and are associated with cardiovascular disease risk. However, it is not yet known whether insulin-like growth factor I (IGF-I) and alanine transaminase (ALT) produced by the liver play roles in hyperinsulinemia and subclinical atherosclerotic process in patients with PCOS and idiopathic hirsutism (IH). Materials and methods:This was a prospective case-controlled study. The study population consisted of 25 reproductive-age PCOS women, 33 women with IH, and 25 control subjects.Results: Mean IGF-I levels and median ALT levels were higher in patients with IH and PCOS than controls, but these differences were not statistically significant. The participants who had a homeostasis model assessment insulin resistance index (HOMA-IR) greater than 2.7 had significantly higher IGF-1 and ALT levels. ALT levels were positively correlated with body mass index, FG, insulin and HOMA-IR. Conclusion:The study illustrated that IGF-1 and ALT levels were significantly higher in patients with increased insulin resistance. Due to short disease duration in younger participants, we did not observe any correlation between IGF-1 and hyperinsulinemia. These findings suggest that increased hepatic production of IGF-I and ALT might be an early indicator of insulin resistance in hirsutism.

BackgroundThyroid volume (TV) has been found to be associated with age, anthropometry, smoking, iodine status and hyperinsulinemia. Hyperinsulinemia is frequent finding in patients with PCOS and has associations with TV. However, the TV has been evaluated only a few studies in patients with PCOS. Therefore, the aim of this study was to evaluate the biochemical and hormonal variables in patients with PCOS comparing with the controls and their relationships between TV.MethodsThis was a case–control study conducted in a training and research hospital. The study population consisted of 47 reproductive-age PCOS women and 30 control subjects. We evaluated anthropometric, biochemical and hormonal parameters as well as thyroid volume in PCOS patients and controls. Insulin resistance was calculated using the homeostasis model assessment insulin resistance index (HOMA-IR).ResultsMean age, BMI, thyroid stimulant hormone (TSH) levels and TV were similar between groups (p<0.05). The HOMA-IR and free T4 levels were higher in patients with PCOS. However, hyperinsulinemia and insulin resistance were not found to be associated with TV. Thyroid volume was positively correlated with the LH and anti TPO levels. The participants were divided into 2 groups according to HOMA-IR levels. The mean TV measurement was higher in group with higher HOMA-IR levels, but the difference was not significant in young age PCOS patients.ConclusionIn early age PCOS patients it was observed that insulin resistance had no effect on TV. In this case, anti TPO and LH have dominant effect on TV. Chronic stimulation with LH and insulin may lead to increase in TV in later stages of the PCOS diseases.

Patients with hyperprolactinaemia have significantly increased thyroid volume, thyroid autoimmunity and nodule prevalence.

Although performing pCLND with TT seems to have an advantage over TT alone as to achieve lower Tg levels in the early post-operative period, Tg levels become comparable following RAI ablation. On the other hand, the patients who have not been treated with adjuvant RAI ablation, also became athyroglobulinemic regardless of the surgical method.

Objective:Polycystic ovary syndrome (PCOS) is a frequent endocrine disease in women. Nodular goiter and autoimmune thyroid disease (AITD) are endocrinologic abnormalities that have high prevalence. The purpose of our study was to detect the prevalence of AITD and nodular goiter in patients with PCOS and investigate whether PCOS-related hormones and metabolic factors affect these thyroid disorders.Material and Methods:Ninety-seven women with PCOS and 71 healthy female volunteers were recruited into the study. Serum-free thyroxine, thyroid-stimulating hormone, anti-thyroperoxidase antibody and anti-thyroglobulin antibody levels were evaluated. Thyroid volume (TV) was calculated using ultrasonography.Results:The body mass index (BMI), Waist/Hip ratio, homeostasis model assessment insulin resistance (HOMA-IR), fasting blood glucose, triglyceride and low-density lipoproteins, and fasting insulin were significantly higher in the PCOS group (p<.05). The control group had significantly higher serum high density lipoprotein cholesterol results (p=.005). The mean TV was 11.4±4.7 mL in the PCOS group and 9.9±2.8 mL in the controls (p=.022). Twenty-nine patients with PCOS (29/97; 29.9%) had thyroid nodules, whereas only eleven control subjects had thyroid nodules (11/71; 15.5%) (p=.043). The frequency of AITD was significantly higher in the PCOS group (p=.001). A statistically significant relationship was found between TV and age, fasting glucose, HOMA-IR, BMI, and fasting insulin (p<.05). Participants with thyroid nodules were older and had higher fasting glucose, BMI, fasting insulin, and HOMA-IR values compared with those without thyroid nodules (p<.05).Conclusion:We demonstrated that TV and frequency of nodular goiter were increased in patients with PCOS. This result was related with insulin resistance. Therefore, we recommend that patients with PCOS must be investigated for the development of nodular goiter and AITD.
