RESUMO

BACKGROUND: Hyperandrogenemia is one of the major diagnostic features for the diagnosis of polycystic ovary syndrome (PCOS). The aim of this study was to estimate the prevalence and the characteristics of hyperandrogenemia in women with PCOS and to investigate the association of clinical and biochemical characteristics with body mass index (BMI) according to the presence of hyperandrogenemia. MATERIALS AND METHODS: We studied 266 women diagnosed with PCOS. Hyperandrogenemia was defined by testosterone (T) and/or free testosterone (FT) and/or ∆4 androstenedione (Δ4-A) higher than 75% of the upper limits of each hormone. Patients were stratified in two groups according to a BMI threshold of 25 kg/m2. RESULTS: Hyperandrogenemia was present in 78.2% of the patients. Elevated levels of T were found in 58.4%, while elevated levels of FT and Δ4-A were found in 42.5% and 34.1% of patients. In normal weight women (BMI≤25 kg/m2) with hyperandrogenemia lower values of hip circumference and HOMA-IR and increased levels of T, FT, Δ4-A, 17-hydroxyprogesterone (17-OHP), dehydroepiandrosterone sulfate (DHEAS), white blood cells (WBC) and neutrophils were observed compared to women without hyperandrogenemia. Also, in overweight women higher levels of T, FT, Δ4-A, 17-OHP, DHEAS and cortisol were measured, while lower thyroid-stimulating hormone (TSH) levels were comparable to women without hyperandrogenemia. CONCLUSION: This study showed high prevalence of hyperandrogenemia in PCOS women. Women with BMI≤25 kg/m2 have significant differences in androgens, WBC, neutrophils and HOMA-IR and women with BMI≥25 kg/m2 in androgens, TSH and cortisol according to the presence or not of hyperandrogenemia.

RESUMO

To evaluate the effect of endometrial injury on clinical outcomes in subfertile women with repeated implantation failures (RIF) undergoing assisted reproduction. In this prospective nonrandomized controlled trial, 103 subfertile women with RIF were included. Fifty-one underwent endometrial injury through hysteroscopy in the early follicular phase of the previous cycle and 52 underwent the standard protocol without any intervention. Live birth and miscarriage were the primary outcomes. Clinical and in vitro fertilization (IVF) cycle characteristics, were also compared between groups. Both groups were comparable in terms of baseline and cycle characteristics. Live birth rates were significantly higher in the study, compared with the control group (18/51 vs. 8/52, odds ratio (OR) = 0.25; 95% confidence interval (CI) = 0.10-0.64; p = 0.020), although miscarriage rates were similar (7/51 vs. 10/52, OR= 0.25; 95%CI= 0.12-0.66; p = 0.452). The rest of the outcomes parameters were comparable between groups. Logistic regression analysis revealed that endometrial injury and duration of subfertility were independent predictors of live birth after control of other variables (OR = 2.818; 95%CI = 1.044-7.605; p = 0.041 and OR = 0.674; 95%CI = 0.461-0.985, p = 0.042, respectively). Endometrial injury induced through office hysteroscopy in the preceding cycle in subfertile women with RIF improves live birth rates.

RESUMO

OBJECTIVE: This study aims to evaluate the potential effects of renal function variations on vascular structure before the development of hypertension. METHODS: This pilot study included 141 postmenopausal women without evidence of renal dysfunction or hypertension. Markers of renal function and levels of glomerular filtration rate (GFR)--using standard calculations (GFR based on levels of creatinine [GFR(epi)]) and newer creatinine and/or cystatin calculations (GFR based on levels of creatinine and cystatin [GFR(cr cystatin)] and GFR based on levels of cystatin [GFR(cystatin)])--were associated with hemodynamic parameters and markers of vascular structure (intima-media thickness [IMT] and presence of atheromatous plaques in carotid and femoral arteries). RESULTS: Levels of GFR(epi), GFR(cr cystatin), and GFR(cystatin) exhibited a significant negative correlation with femoral artery IMT, whereas levels of GFR(epi) correlated significantly with mean carotid bulb (CB) IMT. Multivariate analysis showed that CB-IMT was predicted by GFR(epi) levels and age (ß-coefficient = -0.212, P = 0.020), whereas femoral artery IMT was predicted by GFR(epi) levels (ß-coefficient = -0.293, P = 0.001). GFR(epi) levels lower than the 25th percentile were associated with higher CB-IMT (P = 0.009), femoral artery IMT (P = 0.001), and combined IMT (P = 0.035) compared with higher GFR(epi) levels. Moreover, GFR(epi) levels greater than the 25th percentile were associated with lower odds for the presence of atherosclerotic plaques at the CB and carotid arteries combined (CB: odds ratio, 0.146; P = 0.006; combined: odds ratio, 0.249; P = 0.043) compared with lower GFR(epi) levels. CONCLUSIONS: A mild decrease in renal function within normal limits of GFR is independently associated with the presence of subclinical atherosclerosis in a sample of apparently healthy young postmenopausal women. Assessment of GFR using creatinine (vs cystatin C) levels is a more sensitive marker of its association with IMT and atherosclerotic plaques in this postmenopausal population.

RESUMO

Premature ovarian insufficiency can have significant implications for the affected women. This review assesses the fertility desires, choice of hormone replacement, and the effect of time since menopause on the bone density of these women. This is a retrospective analysis of 223 consecutive new referrals. The average age (mean [± standard deviation]) of the women was 37.35 (± 5.88) years, with 24.1% (n = 19/79) presenting within 12 months of the onset of symptoms, most commonly, vasomotor type symptoms (n = 98/223; 43.9%). Of the women included, 58.7% (n = 131/223) took hormone replacement therapy (HRT), most commonly, an oral (n = 90/131; 68.7%) sequential preparation (n = 91/131; 69.5%), with a significant number of women >40 years of age preferring the transdermal route (n = 26/54; 48.1%; p<0.01). A total of 37.7% (n = 84/223) of the women expressed concerns regarding their future fertility, more notable in women ≤ 40 years (n = 72/142; 50.7%; p < 0.01). Of these, 41.7% (n = 35/84) took HRT, most commonly, a sequential regimen (n = 26/35; 74.3%) with oral estradiol (n = 30/35; 85.7%); 69.5% (n = 155/223) of the women had had a bone densitometry scan performed, with 66.5% (n = 103/155) showing normal bone mineral density (BMD), but a greater likelihood of having reduced BMD the greater the time delay in presentation. No difference was seen for the three broad categories of BMD when further analysed for the cause of premature ovarian insufficiency, but a significant difference was noted for the spinal Z-scores, whereby women who underwent a surgically induced menopause were noted to have lower BMD compared with the other causes (p < 0.01). These findings can be useful in counselling women and guiding clinicians in their management of women with premature ovarian insufficiency.
