RESUMO
Aim: to test effects of estradiol (E2) 1 mg and drospirenone (DRSP) 2 mg in treatment of normal weight menopausal women with typical menopausal symptoms, hyperinsulinism, and grade I hypertension.Material and methods: The participants were 133 menopausal women, mean age 51.82 ± 3.25 years, body mass index (BMI) 24.9 ± 2.6 kg/m2, waist/hip 0.80 ± 0.05, amenorrhoeic period 2.12 ± 2.10 years. All patients were treated with E2 1 mg and DRSP 2 mg during 12 months period. Blood samples were taken at 8 am before and during 12 months of therapy for: glycemia, lipids, hormonal analysis, follicle-stimulating hormone (FSH), luteinizing hormone (LH), E2, testosterone (T), prolactin (PRL), dehydroepiandrosterone sulfate (DHEAS), and sex hormone-binding globulin (SHBG). Oral glucose tolerance test (OGTT) was performed with 75 g glucose in order to assess insulin secretion. All had grade I hypertension 24 h blood pressure monitoring was performed before and after 12 months of therapy.Results: E2/DRSP significantly decreased total cholesterol, low-density lipoprotein (LDL), apolipoprotein B (ApoB), and increased high-density lipoprotein cholesterol (HDL) and apolipoprotein A (ApoA). Insulin area under the curve (AUC) significantly decreased (6586.1 ± 4194.2 vs. 5315.3 ± 2895.0, p < .05) and homeostatic model assessment (HOMA) (3.53 ± 2.18 vs. 3.0 ± 1.8, p < .05). FSH, LH decreased, E2 increased significantly. Of 24 h day blood pressure decreased significantly.Conclusions: E2/DRSP represents suitable therapy for hyperinsulinemic, grade I hypertensive menopausal women with typical symptoms and normal weight.

OBJECTIVE: A high prevalence of insulin resistance (IR) has proven to manifest in patients with adrenal incidentalomas (AI). It has been demonstrated that an increase in IR is related to the size of tumourous masses; additionally, luteinizing hormone (LH)-dependent adrenal pathologies are well documented in patients with LH-responsive adrenal tumours occurring under conditions of physiologically elevated LH. We hypothesized that an association between LH and insulin might play a role in adrenal tumourigenesis and steroidogenesis. DESIGN: The aim of our study was to investigate the association between LH and IR; adrenal tumour size (ATS) and IR; LH and cortisol after the 1 mg overnight dexamethasone test (1 mg DST); and ATS and 1 mg DST cortisol in AI patients. This was a case-control study conducted in the Clinic for Endocrinology, Diabetes and Metabolic Diseases in Belgrade, Serbia. The total study group consisted of 105 menopausal women: 75 AI patients [27 with nonfunctional AI (NAI) and 48 with (possible) autonomous cortisol secretion ((P)ACS)] and 30 age-, BMI-, LH- and menopause duration-matched healthy control (HC) women. To estimate IR, we used homeostasis model assessment (HOMA-IR). RESULTS: Luteinizing hormone and ATS are in a significant positive correlation with HOMA-IR and 1 mg DST cortisol in menopausal patients with AI and (P)ACS. CONCLUSIONS: Our data point to a possible cause-effect relationship between LH and insulin in patients with AI and (P)ACS adding to the body of evidence of their involvement in adrenal tumourigenesis and steroidogenesis.

More empathized approach is required and is obligatory to women with premature ovarian insufficiency (POI) interested for pregnancy. In order to improve fertility rate in POI patients our suggestions would be: (1) To decrease FSH value to 10-15 IU/L by increasing estrogen. Oocyte donation can be suggested after a minimum of six month interval from FSH between 10-15 IU/L and when no dominant follicles are found. (2) To perform oral glucose tolerance test (OGTT). Insulin sensitizing agents has to be included, when indicated, 3-6 month before pregnancy. (3) TSH has to be 1-2.5 mM/L during 3-6 months before pregnancy. (4) Tests for thrombophyllia (Leiden V, FII, MTHFR, PAI) have to be obligatory. They are less expensive than those repeated in vitro fertilizations. Therapy has to be included according to the indications. (5) In order to regulate disturbed immune response in POI patients with endometriosis oral contraceptive therapy is needed for atleast six months prior to the pregnancy. (5) Encourage the patients and advice them about healthy life style and eating habits. (6) Add other drugs, when they are indicated. Complex interplay between endocrine, immunological, haematological, and psychological factors are very often underdetected in POI patients. It is very important to find out the real time for oocyte donation after correcting all the disturbances, improving endometrium receptivity and reaching women's acceptable psychological status. Untreated disturbances induce cardiovascular diseases, diabetes mellitus, thyroid diseases, coagulopathioes etc.

- The aim of the study was to assess the role of the estradiol and progesterone relationship during the late luteal phase and the occurrence of fibrocystic breast disease (FBD). The concentration of estradiol/progesterone was measured in the group of women with FBD as study group (n=50) and control group of women without FBD (n=40). All women had regular ovulation cycles. Blood samples for estradiol (E2), progesterone (P) and prolactin determination were obtained in the morning at 8 am on days 21 and 24 of menstrual cycle. Significant mastalgia and mastodynia history in women with FBD was obtained with yes or no questionnaire. FBD diagnosis was confirmed with ultrasound (size and number of simple cysts). In the control group, a reduced E2/P ratio was noticed from day 21 to day 24 of the cycle (from 14.8±11.5 pg/mL to 9.1±6.1 pg/mL; p<0.05), which was not recorded in the group of women with FBD (study group). Even the slightest disturbance of the E2/P ratio may contribute to the occurrence of FBD with clinical manifestations of mastalgia and mastodynia.

OBJECTIVE: To assess influence of obesity and hormone disturbances on sexuality in the menopause. METHODS: The study included 73 menopausal women, who were divided into groups according to body mass index (BMI) ≥ 26.7 kg/m2. Anthropometric characteristics and blood pressure were measured. Blood was taken at 08:00 for hormones. All the participants filled in McCoy Female Sexual Questionnaire for the assessment of sexual life. STATISTICS: Student's t-test, correlation, analysis of variance (ANOVA). RESULTS: Follicle-stimulating hormone (FSH), luteinizing hormone (LH) and sex hormone-binding globulin (SHBG) were very significantly lower in obese compared to controls. E2 and systolic blood pressure were very significantly, while diastolic blood pressure significantly higher in obese compared to controls. Obese women had significantly decreased frequency of pain during sexual intercourse (3.48 ± 2.64 vs. 4.09 ± 2.81). Influence of age on frequency of sexual intercourse was very significant. Significant influence in interaction between BMI and age on frequency of sexual fantasies as well as significant influence of BMI on satisfaction with partner as lover is also found. CONCLUSION: Obesity has influence on different aspects of sexuality in the postmenopausal women. Our results suggest the need of awareness toward obesity and its impact on sexuality in the menopause.

Primary premature ovarian insufficiency (PPOI) is characterized by hypergonadotropic amenorrhea and hypoestrogenism in women under 40 years of age. PPOI incidence is 1:10,000 in women aged 18-25, 1:1000 in women aged 25-30 and 1:100 in women aged 35-40. In 10%-28% of cases, PPOI causes primary and in 4%-18% secondary amenorrhea. The process is a consequence of accelerated oocyte atresia, diminished number of germinated cells, and central nervous system aging. Specific genes are responsible for the control of oocyte number undergoing the ovulation process and the time to cessation of the reproductive function. A positive family history of PPOI is found in 15% of women with PPOI, indicating the existing genetic etiology. Primary POI comprises genetic aberrations linked to chromosome X (monosomy, trisomy, translocation, deletion) or to autosomal chromosome. Secondary POI implies surgical removal of ovaries, chemotherapy and radiotherapy, and infections. Diagnostic criteria include follicle stimulating hormone level >40 IU/L and estradiol level <50 pmol/L.

Atypical prenatal hormone exposure could be a factor in the development of transsexualism. There is evidence that the 2nd and 4th digit ratio (2D:4D) associates negatively with prenatal testosterone and positively with estrogens. The aim was to assess the difference in 2D:4D between female to male transsexuals (FMT) and male to female transsexuals (MFT) and controls. We examined 42 MFT, 38 FMT, and 45 control males and 48 control females. Precise measurements were made by X-rays at the ventral surface of both hands from the basal crease of the digit to the tip using vernier calliper. Control male and female patients had larger 2D:4D of the right hand when compared to the left hand. Control male's left hand ratio was lower than in control female's left hand. There was no difference in 2D:4D between MFT and control males. MFT showed similar 2D:4D of the right hand with control women indicating possible influencing factor in embryogenesis and consequently finger length changes. FMT showed the lowest 2D:4D of the left hand when compared to the control males and females. Results of our study go in favour of the biological aetiology of transsexualism.

Background: Disrupted sleep affects cardio-metabolic and reproductive health. Obstructive sleep apnea syndrome represents a major complication of obesity and has been associated with gonadal axis activity changes and lower serum testosterone concentration in men. However, there is no consistent opinion on the effect of obstructive sleep apnea on testosterone levels in men. Objective: The aim of this study was to determine the influence of obstructive sleep apnea on total and free testosterone levels in severely obese men. Materials and methods: The study included 104 severely obese (Body Mass Index (BMI) ≥ 35 kg/m2) men, aged 20 to 60, who underwent anthropometric, blood pressure, fasting plasma glucose, lipid profile, and sex hormone measurements. All participants were subjected to polysomnography. According to apnea-hypopnea index (AHI) patients were divided into 3 groups: <15 (n = 20), 15 - 29.9 (n = 17) and ≥ 30 (n = 67). Results: There was a significant difference between AHI groups in age (29.1 ± 7.2, 43.2 ± 13.2, 45.2 ± 10.2 years; p < 0.001), BMI (42.8 ± 5.9, 43.2 ± 5.9, 47.1 ± 7.8 kg/m2; p = 0.023), the prevalence of metabolic syndrome (MetS) (55%, 82.4%, 83.6%, p = 0.017), continuous metabolic syndrome score (siMS) (4.01 ± 1.21, 3.42 ± 0.80, 3.94 ± 1.81, 4.20 ± 1.07; p = 0.038), total testosterone (TT) (16.6 ± 6.1, 15.2 ± 5.3, 11.3 ± 4.44 nmol/l; p < 0.001) and free testosterone (FT) levels (440.4 ± 160.8, 389.6 ± 162.5, 294.5 ± 107.0 pmol/l; p < 0.001). TT level was in a significant negative correlation with AHI, oxygen desaturation index (ODI), BMI, MetS and siMS. Also, FT was in a significant negative correlation with AHI, ODI, BMI, age, MetS and siMS. The multiple regression analysis revealed that both AHI and ODI were in significant correlation with TT and FT after adjustment for age, BMI, siMS score and MetS components. Conclusion: Obstructive sleep apnea is associated with low TT and FT levels in severely obese men.

A growing number of patients with adrenal incidentalomas and subclinical Cushing's syndrome (SCS) led to an increasing number of different guidelines, and diagnostic and treatment recommendations. Excess cortisol secretion in patients with SCS is associated with several comorbidities, such as hypertension, dyslipidemia, type 2 diabetes mellitus, and obesity, which in the long-term increase mortality of these patients. Subtle cortisol secretion affects bone health, quality of life and causes depression, but due to the unapparent clinical features, patients with SCS are often at risk between over and under treatment. This narrative review aimed to summarize the latest recommendations on the approach to the patient with subclinical Cushing's syndrome.

INTRODUCTION: The multiple endocrine neoplasia type 2A (MEN 2A) syndrome, comprising medullary thyroid carcinoma (MTC), pheochromocytoma and primary hyperparathyroidism (PHPT) is most frequently caused by codon 634 activating mutations of the RET (rearranged during transfection) proto-oncogene on chromosome 10. For this codon-mutation carriers, earlier thyroidectomy (before the age of 5 years) would be advantageous in limiting the potential for the development of MTC as well as parathyroid adenomas. CASE OUTLINE: This is a case report of 3-year-old boy from the MEN 2A family (the boy's father and grandmother and paternal aunt) in which cysteine substitutes for phenylalanine at codon 634 in exon 11 of the RET proto-oncogene, who underwent thyroidectomy solely on the basis of genetic information. A boy had no thyromegaly, thyroidal irregularities or lymphadenopathy and no abnormality on the neck ultrasound examination. The pathology finding of thyroid gland was negative for MTC. Two years after total thyroidectomy, 5-year-old boy is healthy with permanent thyroxine replacement. His serum calcitonin level is < 2 pg/ml (normal < 13 pg/ml), has normal serum calcium and parathyroid hormone levels and negative urinary catecholamines. Long-term follow-up of this patient is required to determine whether very early thyroidectomy improves the long-term outcome of PHPT. CONCLUSION: Children with familial antecedents of MEN 2A should be genetically studied for the purpose of determining the risk of MTC and assessing the possibilities of making prophylactic thyroidectomy before the age of 5 years.

INTRODUCTION: Menopause leads to the development of central adiposity, a more atherogenic lipid profile and increased incidence of metabolic syndrome independent of age and other factors. OBJECTIVE: The aim of the study was to investigate the relationships between anthropometric characteristics, sex hormones, lipids and fasting glucose in menopausal women. METHODS: The study included 87 menopausal women, who where divided into groups according to two criteria: BMI > or = 26.7 kg/m2 and BMI > or = 25 kg/m2. Anthropometric characteristics and blood pressure were measured. Blood was taken at 08.00 h for fasting glucose, triglycerides, cholesterol, HDL, LDL, apolipoprotein A, apolipoprotein B, lipoprotein(a) (Lp(a)), C-reactive protein, fibrinogen, follicle stimulating hormone (FSH), luteinizing hormone (LH), prolactin (PRL), estradiol, progesterone, testosterone and sex hormone binding globulin (SHBG). RESULTS: Significant differences between groups were found for weight, BMI, waist, hips circumference, waist/hip ratio (WHR), systolic and diastolic blood pressure, Lp(a), FSH, LH, PRL (for systolic blood pressure p < 0.05, for the rest p < 0.01) and fasting glucose (p < 0.05). In obese and overweight women with BMI > or = 26.7 kg/m2 significant negative correlations were found for FSH and glucose, SHBG and LDL, SHBG and total cholesterol, SHBG and glucose, BMI and HDL, WC and HDL. In obese and overweight women with BMI > or = 25 kg/m2 significant negative correlations were found for BMI and HDL, waist circumference (WC) and HDL, WHR and HDL, FSH and glucose, SHBG and glucose; significant positive correlations were between BMI and glucose, WC and glucose and WHR with triglycerides. CONCLUSION: Gaining weight and decreased SHBG are related to dyslipidemia and increased fasting glucose confirming increased incidence of metabolic abnormalities in the menopause.

INTRODUCTION: Premature ovarian failure (POF) is characterized by amenorrhea, hypergonadotropism and hypoestrogenism in women bellow 40 years. Osteoporosis is one of the late complications of POF. OBJECTIVE: To correlate collagen type I alpha1 (COLIA1) gene polymorphism with bone mineral density (BMD) in women with POF. METHODS: We determined the COLIA1 genotypes SS, Ss, ss in 66 women with POF. Single nucleotide polymorphism (G toT substitution) within the Sp 1-binding site in the first intron of the COLIA1 gene was assessed by polymerase chain reaction (PCR) followed by single-stranded conformation polymorphism (SSCP) analysis. Bone mineral density (BMD) was measured at the lumbar spine region by dual X-ray absorptiometry. STATISTICS: Kruskal-Wallis ANOVA, Chi-square test, Spearman correlation test. RESULTS: The relative distribution of COLIA1 genotype alleles was SS - 54.4%, Ss - 41.0% and ss - 4.5%. No significant differences were found between genotype groups in body mass index, age, duration of amenorrhea or BMD. A significant positive correlation was observed between BMI and parity. CONCLUSION: The COLIA1 gene is just one of many genes influencing bone characteristics. It may act as a marker for differences in bone quantity and quality, bone fragility and accelerated bone loss in older women. However, in young women with POF, COLIA1 cannot identify those at higher risk for osteoporosis.

OBJECTIVE: The aim of this study was to estimate insulin sensitivity (IS) in nondiabetic patients with adrenal incidentalomas (AI): nonfunctional adrenal incidentalomas (NAI) and patients with AI and subclinical Cushing's syndrome (SCS). METHODS: Based on the inclusion criteria (normal fasting glucose levels, no previous history of impaired fasting glucose and/or diabetes, and no medications or concomitant relevant diseases) and the exclusion criteria (pheochromocytoma, overt hypercortisolism, hyperaldosteronism, adrenal carcinoma, metastasis of extra-adrenal tumors, extra-adrenal malignancies), 142 subjects were drawn from a series of patients with AI. The subjects were age-, sex- and body mass index (BMI)-matched: 70 with NAI (50 women and 20 men), 37 with AI and SCS (31 women and 6 men) and 35 healthy control (HC) subjects (30 women and 5 men). The oral glucose tolerance test (OGTT) and several indices of insulin sensitivity (IS) were used: homeostasis model assessment (HOMA), quantitative insulin sensitivity check index (QUICKI), triglycerides and glucose index (TyG), index of whole-body insulin sensitivity (ISI-composite) and glucose to insulin ratio (G/I). RESULTS: There was a significant difference in IS between subjects with NAI and HC (HOMA, p=0.049; QUICKI, p=0.036; TyG, p=0.002; ISI-composite, p=0.024) and subjects with SCS and HC (AUC insulin, p=0.01; HOMA, p=0.003; QUICKI, p=0.042; TyG, p=0.008; ISI-composite, p=0.002). There was no difference in the tested indices of IS between subjects with NAI and SCS (p>0.05). However, subjects with SCS had a significantly higher prevalence of impaired glucose tolerance and higher area under the curve for glucose than subjects with NAI (p=0.0174). The linear regression analysis showed that 1 mg-DST cannot be used as a predictor of HOMA (R(2)=0.004, F=0.407, p=0.525). Significant relationship was found between 1 mg-DST and ISI-composite (R(2)=0.042, F=4.981, p=0.028) but this relationship was weak and standard error of estimate was high. The linear regression model also showed that ACTH cannot be used as a predictor of HOMA (R(2)=0.001, F=0.005, p=0.943) or ISI-composite (R(2)=0.015, F=1.819, p=0.187). CONCLUSIONS: Insulin resistance is a major cardiovascular risk factor; therefore, the assessment of IS in patients with AI, even nonfunctional, has a valuable place in the endocrine workup of these patients.

INTRODUCTION: Cushing's syndrome results from inappropriate exposure to excessive glucocorticoids. Untreated, it has significant morbidity and mortality. CASE OUTLINE: A 38-year-old woman with a typical appearance of Cushing's syndrome was admitted for further evaluation of hypercortisolism. The serum cortisol level was elevated without diurnal rhythm, without adequate suppression of cortisol after 1 mg dexamethasone suppression test. 24-hour urinary-free cortisol level was elevated. Differential diagnostic testing indicated adrenocorticotrophin (ACTH)-dependent lesion of the pituitary origin. Pituitary abnormalities were not observed during repeated MRI scanning. Inferior petrosal sinus sampling (IPSS) was performed: 1) Baseline ratio ACTH inferior petrosal sinus/peripheral was <2; 2) Corticotropin-releasing hormone (CRH) stimulated ratio ACTH inferior petrosal sinus/peripheral was <3; 3) Baseline intersinus ratio of ACTH was <1.4; 4) Increase in inferior petrosal sinus and peripheral ACTH of more than 50 percent above basal level after CRH; 5) Baseline ratio ACTH vena jugularis interna/peripheral was >1.7. Transsphenoidal exploration and removal of the pituitary tumor was performed inducing iatrogenic hypopituitarism. Postoperative morning serum cortisol level was less than 50 nmol/l on adequate replacement therapy with hydrocortisone, levothyroxine and estro-progestagen. CONCLUSION: No single test provides absolute distinction, but the combined results of several tests generally provide a correct diagnosis of Cushing's syndrome.

Premature ovarian failure (POF) is the occurrence of hypergonadotropic hypoestrogenic amenorrhea in women under the age of forty years. It is idiopathic in 74-90% patients. Known cases can be divided into primary and secondary POF. In primary POF genetic aberrations can involve the X chromosome (monosomy, trisomy, translocations, deletions) or autosomes. Genetic mechanisms include reduced gene dosage and non-specific chromosome effects impairing meiosis, decreasing the pool of primordial follicles and increasing atresia due to apoptosis or failure of follicle maturation. Autoimmune ovarian damage is caused by alteration of T-cell subsets and T-cell mediated injury, increase of autoantibody producing B-cells, a low number of effector/cytotoxic lymphocyte, which decreases the number and activity of natural killer cells. Bilateral oophorectomy, chemotherapy, radiotherapy and infections cause the secondary POF. Symptoms of POF include irritability, nervousness, loss of libido, depression, lack of concentration, hot flushes, weight gaining, dry skin, vaginal dryness, frequent infections etc.The diagnosis is confirmed by the level of FSH of over 40 IU/L and estradiol below 50 pmol/L in women aged below 40 years. Biochemical and other hormonal analysis (free thyroxin, TSH, prolactin, testosterone), karyotype (<30 years of age), ultrasound of the breasts and pelvis are advisable. Optimal therapy is combined estrogen progestagen therapy given in a sequential rhythm, after excluding absolute contraindications. Testosterone can be added to adnexectomized women and those with a low libido. Sequential estrogen progestagen replacement therapy is the first line therapy for ovulation induction in those looking for pregnancy and after that oocyte donation will be advised. Appropriate estro-progestagen therapy improves the quality of life and prevents complications such as cardiovascular diseases, osteoporosis, stroke etc.

INTRODUCTION: Hypoestrogenic status in the menopausal women shows a shift to a central android fat distribution and metabolic syndrome (MIS). Related metabolic changes and hypertension increase the risk for cardiovascular (CV) diseases. The aim of this study was to investigate the influence of duration of menopause, anthropometric and hormonal parameters on metabolic syndrome. MATERIAL AND METHODS: 50 obese women were examined with BMI = 31.92 = 5.83 kg/m2, age 54.40 +/- 3.64, time since menopause 5.90 +/- 5.46 years. Control group consisted of 37 normal weight women with BMI = 23.50 +/- 2.13 kg/m2, age 53.92 +/- 3.95, time since menopause 5.96 +/- 4.92 years. Anthropometric characteristics and blood pressure were measured. Blood was taken at 8 am for: fasting glucose, triglycerides, cholesterol, HDL, LDL, apolipoprotein A (ApoA), apolipoprotein B (ApoB), lipoprotein(a) (Lp(a)), C-reactive protein (CRP), fibrinogen, FSH, LH, prolactin, estradiol, progesterone, testosterone and sex hormone binding globulin (SHBG). RESULTS: In obese women significant negative correlations were found for: BMI anid HDL (p < 0.05), waist and HDL (p < 0.05), FSII and systolic blood pressure (p < 0.01), FSH and fasting glucose (p < 0.05), LH and waist (p < 0.05), SHBG and fasting glucose (p < 0.05). A positive correlation was found for time since menopause and waist/hip ratio (p < 0.05). In controls positive correlations were found for: waist/hip ratio and systolic and diastolic blood pressure (p < 0.05), LH and HDL (p < 0.05). estradiol and diastolic blood pressure (p < 0.05). Negative correlations were detected for estradiol and waist (p < 0.05), time since menopause and HDL (p < 0.05). CONCLUSION: Gaining weight together with menopausal endocrine changes cause metabolic and hemodynamic imbalances, which contribute to risk for cardiovascular diseases.

INTRODUCTION: Neurofibromatosis type 1 is one of the most common genetically transmitted diseases with a high index of spontaneous mutations and extremely varied and unpredictable clinical manifestations. It is diagnosed by the existence of certain clinical criteria. The presence of numerous localised cutaneous neurofibromas or a plexiform neurofibroma is virtually pathognomonic of neurofibromatosis type 1. The incidence of pheochromocytoma in neurofibromatosis type 1 is 0.1-5.7%. CASE OUTLINE: A 56-year old female patient was admitted for further evaluation of incidental adrenal tumour previously diagnosed on computerized tomography (CT). She had previously unrecognized neurofibromatosis type 1 and a clinical picture which could remind of pheochromocytoma. None of the catecholamine samples in 24 hr urine indicated functionally active pheochromocytoma. Chromogranin A was moderately increased. Decision for operation was made after performing the image techniques. Adrenal incidentaloma had features of pheochromocytoma on abdominal magnetic resonance imaging (MRI), with positive 131I-MIBG (iodine 131-labelled metaiodobenzylguanidine scintigraphy). After being treated with phenoxybenzamine and propranolol, she was operated on. The pathohistological finding showed the case of left adrenal pheochromocytoma. CONCLUSION: Detailed diagnostic procedure for pheochromocytoma should be performed with patients having neurofibromatosis type 1 and adrenal incidentaloma. Pheochromocytomas are rare tumours with fatal outcome if not duly recognized and cured.

INTRODUCTION: Menopause induces redistribution of fat mass and development of abdominal obesity, increasing risk for metabolic syndrome (MS) by 60%. Related cardiovascular diseases become a leading cause of morbidity and mortality in women after fifty years of age. OBJECTIVE: The aim of this study was to investigate the influence of gaining weight on components of MS in the menopause. METHOD: The study included 50 obese women, BMI=31.92 +/- 5.83 kg/m2, age 54.40 +/- 3.64, time since menopause 5.90 +/- 5.46 years, and 37 normal weight women, BMI = 23.50 +/- 2.13 kg/m2, age 53.92 +/- 3.95, time since menopause 5.96 +/- 4.92 years. Both groups were divided according to the presence of MS into two subgroups. Anthropometric characteristics and blood pressure were measured. Blood was taken at 8 am for the following: fasting glucose, triglycerides, cholesterol, HDL, LDL, apolipoprotein A (ApoA), apolipoprotein B (ApoB), lipoprotein(a) (Lp(a)), C-reactive protein (CRP), fibrinogen, FSH, LH, prolactin, oestrogen, progesterone, testosterone and sex hormone-binding globulin (SHBG). RESULTS: 66% of obese women had MS compared with 22% normal weight women. Significant differences between groups were found for the following: weight, BMI, waist, hip circumference, waist/hip ratio, diastolic blood pressure, Lp(a), FSH, LH, prolactin (all p < 0.01) and fasting glucose (p < 0.05). Obese women with and without MS were significantly diverse for the following: waist/hip ratio, systolic blood pressure and fasting glucose (all p < 0.01); age, BMI, waist circumference, triglycerides, HDL, Lp(a) and SHBG (all p < 0.05). Normal weight women with and without MS had significantly different values of waist/hip ratio, systolic, diastolic blood pressure, triglycerides (all p < 0.01); HDL and testosterone (p < 0.05). Significant differences were found between obese and normal weight women with MS in anthropometric characteristics, ApoA, Lp(a), fibrinogen (all p < 0.01) and FSH (p < 0.05). CONCLUSION: Abdominal obesity significantly increases incidence of MS as a cluster of cardiovascular risk factors in the menopause.
