Polycystic ovary syndrome (PCOS) is a heterogeneous disorder with widespread systemic manifestations affecting 5-10% of women of reproductive age. The accompanying insulin resistance and hypeinsulinemia mark this syndrome as a prediabetic state, with high incidence of impaired glucose tolerance, gestational diabetes, and overt diabetes. Other metabolic and biochemical changes, such as hypertension and dyslipidemia, increase the risk of cardiovascular disease. Fertility may also be impaired due to anovulation, impaired implantation, and higher rates of spontaneous abortions. All of these effects may also be related to hyperinsulinemia. Metformin, as insulin-sensitizing drug, is being evaluated for its potential long-term disease-modifying effect, such as prevention of diabetes. Its use may also help restore spontaneous ovulation and improve menstrual cyclicity, improve the success rate of induction of ovulation with clomiphene citrate and FSH, and decrease the high rate of ovarian hyperstimulation and early pregnancy loss. Nevertheless, these new exiting potential benefits of metformin should be evaluated in large randomized controlled studies, and clinicians must counsel women appropriately before the initiation of metformin therapy.

Subjects with obesity, family history of type 2 diabetes, polycystic ovary syndrome, previous gestational diabetes, dyslipidemia, hypertension, impaired glucose tolerance or impaired fasting glucose, and those with metabolic syndrome are at risk for the development of type 2 diabetes. Some of them are also at risk for cardiovascular disease. Some underlying abnormalities such as insulin resistance, endothelial dysfunction, and low-grade chronic inflammation are frequently present and closely associated in all these groups. The flow of substrates, hormones, and cytokines from visceral fat to skeletal muscle and to the endothelial cells, along with some genetic abnormalities that lead to impaired insulin action in the peripheral tissues and to impaired insulin-stimulated nitric oxide production in endothelial cells, may play a role in establishing these shared metabolic and vascular derangements. Weight loss, thiazolidinediones, and metformin improve vascular function in subjects at risk for type 2 diabetes and may prove to reduce cardiovascular events in these individuals.

Various groups at risk for type 2 diabetes have been identified, including individuals with family history of type 2 diabetes, obesity, prior gestational diabetes, polycystic ovary syndrome, metabolic syndrome, hypertension, dyslipidemia and particularly those with pre-diabetes (impaired glucose tolerance and/or impaired fasting glucose). To various degrees, all these groups have also been identified with significant vascular abnormalities that range from endothelial dysfunction and low-grade or sub-clinical inflammation to evident atherosclerosis. The mechanisms involved in establishing a link between the risk of type 2 diabetes and vascular dysfunction are multiple and complex. The presence in the circulation of various cytokines, hormones and substrates associated with increased visceral fat and insulin resistance, the frequent appearance of associated cardiovascular risk factors and/or the possibility of some genetically determined intrinsic vascular abnormalities are all explanatory mechanisms that are being evaluated in clinical research. Whereas the possibility of appreciating a significant reduction in cardiovascular outcomes in long-term prospective clinical trials in all these groups at risk for type 2 diabetes is still lacking, understanding these mechanisms and recognizing how various interventions may improve vascular health is a worthwhile area of research that may translate into important clinical strategies to reduce the burden of type 2 diabetes and cardiovascular disease.

Menopause-related oestrogen deficiency increases the risk of cardiovascular disease (CVD). The presence of abdominal obesity, dyslipidemia, hypertension, fasting hyperglycaemia or impaired glucose tolerance further aggravates the CVD risk imposed by menopause. A detailed personal history should be recorded, covering PCOS, gestational diabetes mellitus, alcohol intake and smoking, as well as a family history of cardiovascular disease. Screening of the a-symptomatic post-menopausal woman should include fasting lipid profile, plasma glucose and liver, renal and thyroid function tests. Serum low-density lipoprotein cholesterol (LDL-c)>130 mg/dL is associated with an increased risk of CVD. Levels of triglycerides (TG)>or=150 mg/dL and high-density lipoprotein cholesterol (HDL-c)<or=50 mg/dL coupled with an increase in small dense LDL and very low-density lipoprotein (VLDL) particles constitute the atherogenic dyslipidemia, which characterizes the metabolic syndrome. In women with previous VTE episodes, screening for thrombophilia is advisable, as well as an estimation of baseline homocysteine and C-reactive protein (CRP). Non-pharmacological intervention should be targeted towards smoking cessation, a low-salt, low-fat, high-fibre diet and increased physical activity.

The objective of this study was to determine if early pregnancy maternal plasma lipid concentrations are elevated in women who later developed gestational diabetes mellitus (GDM) as compared with women who do not. Women, recruited prior to 16 weeks gestation, were followed until delivery. Maternal plasma lipid concentrations were measured in samples collected at 13 weeks gestation on average. Generalized linear models were used to estimate relative risks (RR) and 95% confidence intervals (95% CI). 5.5% of the cohort (47/851) developed GDM. Elevated triglyceride (TG) was positively associated with GDM risk (p for trend <0.001). After adjusting for maternal pre-pregnancy adiposity and other confounders, women with TG concentrations > or =137 mg/dl experienced a 3.5-fold increased risk of GDM (95% CI: 1.1-10.5) as compared with women who had concentrations <96 mg/dl. We noted a linear component of trend in risk of GDM with increasing plasma TG. Each 20mg/dl increase in TG was associated with a 10% increase in GDM risk (RR=1.1; 95% CI: 1.0-1.3). Associations between GDM risk and plasma concentrations of other lipids (i.e., total cholesterol, high-density lipoprotein, and low-density lipoprotein) were not evident. Larger prospective studies are needed to confirm our findings and to identify modifiable determinants of pregnancy-associated dyslipidemia.

Pregnancy in acromegaly is a rather rare event since the fertility is reduced in acromegalic women. Besides, metabolic complications of acromegaly are harmful to both mother and fetus. Little is known about the outcome of pregnancy in acromegalic women. Here, we report seven cases of pregnancy out of 48 acromegalic women followed for 16 years. At diagnosis, five patients had macroadenoma, one patient had microadenoma and the size of the tumor was not documented in one patient. In one patient, acromegaly was initially diagnosed during pregnancy at 29 weeks. When she was 33 weeks, she developed pituitary apoplexy and had an emergency transsphenoidal resection of her macroadenoma during which she also had a cesarian section and delivered a healthy baby girl. In the remaining six patients, pregnancy occurred 6 to 64.5 months after the adenoma resection. Three patients received radiotherapy before getting pregnant. In three patients, pregnancy occurred during bromocriptine treatment and the drug was withdrawn. In one patient, pregnancy occurred during chronic octreotide treatment and therapeutic abortion was performed. In another patient, therapeutic abortion was performed because of uncontrolled disease. In the remaining four patients, there were neither worsening of symptoms nor tumor growth. All four patients gave birth to full-term healthy infants. Out of our seven patients, two developed gestational diabetes mellitus which was controlled with diet. None of the patients had coronary artery disease, hypertension or dyslipidemia. These cases show that pregnancy might be uneventful in acromegalic women when the disease is controlled with prior surgery and radiotherapy.

The incidence and prevalence of diabetes is increasing worldwide. National recommendations for screening and diagnosis of diabetes, hypertension, and dyslipidemia provide a basis for early detection, treatment, and intervention that may potentially decrease related complications, and personal and economic costs of the disease. Most important is that knowledge exists about who is at risk for diabetes by weight, family history of diabetes, ethnicity, and history of gestational diabetes that allows for the development and implementation of diabetes primary prevention programs. Multiple national health care providers, systems of care, and communities that can be used to guide such prevention, early screening, and disease detection and intervention programs aimed at decreasing the burden of diabetes.

Dyslipidemia is associated with increased low-density lipoprotein (LDL) susceptibility to oxidation, a phenomenon associated with endothelial dysfunction, atherosclerosis, cell toxicity, and intrauterine growth retardation. The present study was designed to determine if women developing gestational diabetes mellitus (GDM) have both increased plasma lipids and LDL susceptibility to oxidation throughout pregnancy. We also wanted to study the effects of obesity upon these parameters. A nested case-control study was carried out in 45 women with uncomplicated pregnancies and 62 women diagnosed with GDM following the criteria of the American Diabetes Association. In all women, blood was drawn at 15, 24, and 32 weeks of gestation. Low-density lipoprotein oxidation was initiated by the addition of CuCl2, and formation of conjugated dienes was monitored. Glucose, cholesterol, triglycerides, vitamin E, estradiol, and progesterone were determined. In GDM, elevated levels of glucose, cholesterol, and triglycerides were observed when compared with the control group even in the first trimester, before the detection of diabetes. In the control group, the lag phase in the LDL oxidation was 85.3, 84.4, and 95.6 minutes at 15, 24, and 32 weeks of pregnancy, compared with 63.3, 63.4, and 74.5 minutes in the GDM group (P < .001 in the 3 periods). These differences remained when adjusted for the body mass index. In a multiple linear regression analysis, a negative correlation was observed between the lag phase and the body mass index (P < .001) and cholesterol (P < .001), whereas a positive one appeared with vitamin E (P < .05) and time of gestation (P < .001). In pregnancy, GDM increases LDL susceptibility to oxidation. Obesity and hypercholesterolemia further exacerbate this effect.

Gestational diabetes (GDM) has increased risk of diabetes (DM2), a coronary artery disease (CAD) equivalent. The aim of this study was to determine the prevalence of impaired glucose metabolism (IGM) in GDM and its association with risk factors for CAD. A cohort of 109 women with GDM underwent a glucose tolerance test which classified them into three groups: diabetic (DM2) (fasting glucose (G) >or=126mg/dl or plasma glucose 2h (2-h G) >or=200mg/dl); impaired glucose tolerance (IGT) (G 100-125mg/dl and/or 2-h G 140-199mg/dl); and normal (N) (G<100mg/dl and/or 2-h<140mg/dl). They were compared for pre-gestational (PBMI) and current (CBMI) body mass index, systolic (SBP) and diastolic blood pressure (DBP), G, lipids, fibrinogen and C-reactive protein (hsCRP). Thirty two months after delivery, 17.4% presented DM2, 39.4% IGT and 43.1% were N. PBMI, CBMI, SBP and DBP were significantly higher in the DM2 than N. G was higher in DM2 and IGT. HDL-cholesterol (HDL-C) was higher in the N (p=0.02) and the triglycerides (TG) were higher in DM2 (p=0.02). The groups showed significantly different levels of hsCRP (p=0.002). We conclude that the high prevalence of IGM, overweight/obesity, dyslipidemia and altered inflammatory markers, make GDM a high-risk situation for CAD.

Diabetes type 2 has increased in adult women due to higher frequency of obesity and sedentary lifestyle, and thus cardiovascular diseases have increased. Hyperglycemia control and, collaterally, high blood pressure and dyslipidemia correction are the basis of its therapy. This paper evaluates oral antidiabetic drugs effectiveness and preference. Gestational diabetes is a cause of morbidity and mortality in fetuses and newborns, it has to be timely diagnosed, and needs a strict control, same to diabetes type 1. Gyneco-obstetrical doctor must be alert to diabetes signs and closely work in its therapy.
