Polycystic ovary syndrome (PCOS) is extremely heterogeneous in terms of clinical manifestations. The variability of the syndrome’s phenotype is derived from the genetic and molecular heterogeneity, with a great deal of environmental factors that may have long-term health consequences, such as metabolic and cardiovascular (CV) diseases. There is no doubt that women with PCOS suffer from metabolic complications more than their age-matched counterparts in the general population and at an earlier age. Obesity, low steroid hormone-binding globulin (SHBG), hyperandrogenemia, insulin resistance, and compensatory hyperinsulinemia are biomediators and early predictors of metabolic complications in PCOS. Doubts remain about the real risk of CV diseases in PCOS and the molecular mechanisms at the basis of CV complications. Based on that assumption, this review will present the available evidence on the potential implications of some biomediators, in particular, hyperandrogenism, estrogen-progesterone imbalance, insulin resistance, and low SHBG, in the processes leading to CV disease in PCOS, with the final aim to propose a more accurate CV risk assessment.

Polycystic ovary syndrome (PCOS), an endocrinological disorder with lipid disturbances leads to a wide spectrum of clinical manifestations including menstrual irregularities, infertility, obesity and hyperandrogenism. This study aimed to determine the levels of lipid profile and sex hormones and its effect on PCOS from a State in southern India. This comparative hospital-based study was conducted in the State of Karnataka, India from June 2019 to January 2020. 57 age-matched PCOS and 67 healthy controls were enrolled for the study. Fasting glucose, insulin, lipid profile and sex hormone levels were analyzed after taking informed consent from all participants. The mean age of patients with PCOS was 25.05 ± 6.04 years and the mean age of subjects in the control group was 27.36 ± 7.08 years. Lipid profile showed statistically significant increased levels of triglyceride 147.3±86.6 (p<0.05) and decreased levels of HDL 52.2±8.7 (p<0.05) whereas hormones LH and testosterone were significantly higher in women with PCOS when compared to controls. The altered lipid profile, sex hormone and insulin levels exhibit a key role in the pathophysiology of PCOS that affects health. Insulin resistance is found to be linked with dyslipidemia in PCOS. Our findings suggest that the differences found may play a key role in the pathophysiology of PCOS which in turn affects the health and therefore it is advisable to emphasize the necessity for screening insulin resistance and perform early and periodic examination of lipid profile and sex hormones in women with PCOS to reduce complications.

Abstract This work is a continuation of an earlier article published in this journal (no. 91/1: “Current aspects of polycystic ovary syndrome I: definition, pathophysiology, clinical manifestations, diagnosis and complications”). As the pathology of polycystic ovary syndrome is not fully known, the treatments used do not constitute a causal therapy, only pathogenetical interventions to break the vicious circles of pathological events. It does not currently have a universal therapeutic procedure or an approved specific drug. Treatment may be aimed at reducing hyperandrogenism, inducing ovulation and preventing complications. The patient’s complaints and desire for becoming pregnant should also be taken into account. In mild cases, an appropriate lifestyle (prevention/treatment of obesity) is sufficient, i.e. a 5-10% reduction in body weight can already result in significant improvement and also serves to prevent late complications (diabetes, hypertension, cardiovascular disease, hyperlipidemia). Oral contraceptives and antiandrogens are mainly used to treat hyperandrogenism (hirsutism, acne, and alopecia). A contraceptive whose progestogen component has antiandrogenic properties, or at least is androgen-neutral, is preferred, such as third-generation contraceptives. However, combined contraceptives (containing gestodene, desogestrel, drospirenone and cyproterone acetate) may increase the risk of venous thromboembolism and are therefore contraindicated in case of hypercoagulability. Antiandrogens (cyproterone acetate, spironolactone, finasteride, etc.) can also be used independently, but only with effective contraception (as these can cause feminization of the male fetus). Insulin resistance plays a crucial role in the development of this disease. Metformin is used as primary therapy, as it also has many other beneficial effects (e.g. cardiovascular and anti-cancer) described in recent years. These pleiotropic effects and their subtle mechanisms are discussed in detail. We highlight the possibilities of avoiding side effects and the current interpretation of rare contraindications (acidosis, hypoxic conditions, renal damage). Insulin resistance lowering agents include thiazolidinediones, acarbose, GLP-1 agonists, vitamin D, resveratrol, octreotide, but the beneficial effects of myoinositol and D-chiro-inositol are also mentioned. In the last part of the paper, the treatment options for infertility are discussed, highlighting the efficacy of clomiphene citrate, gonadotropins (“step-up”, “step- down” methods), IVF techniques, and ovarian drilling used for ovulation induction. We detail the importance and possibilities of the prevention of ovarian hyperstimulation syndrome and multiple pregnancies.

Abstract Polycystic ovary syndrome (PCOS) is the most frequent endocrine disease among women with childbearing potential, the best-known cause of hirsutism, with a hypothesized prevalence of 8-22%. The first part of the paper discusses the conceptional evolution of the syndrome, from its description in 1935 by Stein and Leventhal till today. It describes the changes in the criteria systems, emphasizing that the Rotterdam criteria, proposed in 2003 by the European Society for Human Reproduction and Embryology/American Society for Reproductive Medicine, are still valid today. This system basically differs from earlier (1990) NIH-criteria in one aspect: it introduced two newer phenotypes, one without hyperandrogenism and the other with ovulatory cycles, so it distinguishes 4 phenotypes. The etiology and pathogenesis of PCOS is heterogeneous, multifactorial, poorly understood. We present the 3 leading hypotheses (1 - hypothalamo-hypophyseal disturbances, 2 – primary enzyme disorders in ovarian, or ovarian/adrenal steroidogenesis, resulting primarily in hyperactivity of 17alpha-hydroxylase/17,20-lyase, 3 – insulin resistance-hyperinsulinism and other metabolic dysfunctions). We emphasize the role of genetically determined hyperandrogenism, that of insulin resistance-hyperinsulinism and the importance of reinforcing each other. Subsequently, the aggravating aspects of the frequently associated metabolic syndrome are discussed, and then the effects of the mentioned pathological processes on the endocrine and other organ structures participating in the regulation of sexual functions. We stress the hypothetical role of perinatal and pubertal androgen exposition in the pathogenesis of PCOS. The mechanisms of anovulation and those of the endometrial lesions are discussed, too. The clinical manifestations, the paraclinical and laboratory examinations, the positive and differential diagnosis and the complications are also presented. We intend to deal with the therapeutic aspects of PCOS in an upcoming paper.

Pregnancy hypertensive disorders such as Preeclampsia (PE) are strongly correlated with insulin resistance, a condition in which the metabolic handling of D-glucose is deficient. In addition, the impact of preeclampsia is enhanced by other insulin-resistant disorders, including polycystic ovary syndrome and obesity. For this reason, there is a clear association between maternal insulin resistance, polycystic ovary syndrome, obesity and the development of PE. However, whether PE is a consequence or the cause of these disorders is still unclear. Insulin therapy is usually recommended to pregnant women with diabetes mellitus when dietary and lifestyle measures have failed. The advantage of insulin therapy for Gestational Diabetes Mellitus (GDM) patients with hypertension is still controversial; surprisingly, there are no studies in which insulin therapy has been used in patients with hypertension in pregnancy without or with an established GDM. This review is focused on the use of insulin therapy in hypertensive disorders in the pregnancy and its effect on offspring and mother later in life. PubMed and relevant medical databases have been screened for literature covering research in the field especially in the last 5-10 years.
