Serum 25-hydroxyvitamin D concentrations in obese and non-obese women with polycystic ovary syndrome

PurposeTo investigate the correlation between serum 25-hydroxyvitamin D (25-OH-VD) concentrations and metabolic parameters in obese and non-obese women with polycystic ovary syndrome (PCOS).MethodsOne hundred women with PCOS were divided into two groups, obese and non-obese, according to their body mass index (BMI). Waist-to-hip ratio (WHR), Ferriman–Gallwey score, homeostasis model assessment of insulin resistance (HOMA-IR), total cholesterol, triglycerides, calcium, 25-OH-VD, LH/FSH, total testosterone, and DHEAS were measured.ResultsThe serum 25-OH-VD mean levels were 56.31% lower in the obese PCOS patients. There was an association of increased HOMA-IR, BMI, WHR, triglycerides, total testosterone, and DHEAS with decreased 25-OH-VD concentrations in the obese PCOS patients.ConclusionLow serum 25-OH-VD concentrations result from the presence of obesity and insulin resistance. However, the dependency between PCOS and hypovitaminosis D is questionable. Hypovitaminosis D should be kept in mind while managing obese women with PCOS.

The Relationship between Clinico-biochemical Characteristics and Psychiatric Distress in Young Women with Polycystic Ovary Syndrome

The relationship between clinico-biochemical characteristics and self-reported psychological parameters in 42 women with polycystic ovary syndrome (PCOS) and 42 age-matched healthy controls was examined. The General Health Questionnaire was used (GHQ-12) to ascertain emotional distress and the Beck Depression Inventory (BDI) to determine depressive symptoms. Emotional distress, depressive symptoms, hirsutism score, body mass index (BMI), waist-to-hip ratio (WHR), luteinizing hormone/follicle-stimulating hormone ratio, serum total testosterone, dehydroepiandrosterone sulphate levels and the insulin resistance index were significantly greater in women with PCOS than in healthy women. The BDI and GHQ-12 scores of the women with PCOS were significantly higher than those of the control group (BDI, 11.69 ± 9.49 vs 5.80 ± 4.58; GHQ-12, 3.38 ± 3.38 vs 1.54 ± 1.97, respectively), and BMI and WHR were positively correlated with the BDI and GHQ-12 scores. Clinicians should be aware of the increased risk of emotional distress and depression in women with PCOS, especially those who are obese, and of the need to screen these patients for such symptoms.

Increased visfatin and leptin in pregnancies complicated by pre-eclampsia

Objective. To evaluate the role of the adipokines, visfatin and leptin in the pathophysiology of pre-eclampsia and how their concentrations correlate with the severity of the disease and abnormal Doppler velocimetry. Methods. A cross-sectional study was carried out in 72 pregnant women (30 patients with mild pre-eclampsia, 20 patients with severe pre-eclampsia and 22 healthy normotensive pregnant women) during the third trimester of pregnancy. The maternal levels of plasma visfatin and serum leptin were determined in all cases by enzyme immunoassay and enzyme-linked immunosorbent assay, respectively. The uterine artery and umbilical artery RI were determined by Doppler analysis in all cases. Results. Plasma visfatin levels and serum leptin levels were higher in patients with pre-eclampsia than in the normotensive pregnant women. Six patients with mild pre-eclampsia and five patients with severe pre-eclampsia had abnormal Doppler velocimetry. Visfatin and leptin levels of pre-eclamptic patients with abnormal Doppler velocimetry were significantly higher than they were in those with normal Doppler velocimetry. Serum leptin levels were positively correlated with plasma visfatin level in cases of pre-eclampsia. Conclusions. These findings suggest that increased maternal levels of leptin and visfatin may be involved in the pathogenesis of pre-eclampsia, and measurement of these adipokines may be useful in assessment of the severity of disease.

Serum trace elements and heavy metals in polycystic ovary syndrome

Objective: We aimed to investigate the serum levels of essential trace elements copper (Cu), zinc (Zn), manganese (Mn), magnesium (Mg) and heavy metals cadmium (Cd), cobalt (Co) and lead (Pb) in the patients with polycystic ovary syndrome (PCOS). Methods: A total of 65 (35 patients with PCOS and 30 healthy controls) women were included in the study. Serum Cu, Zn, Mn, Pb, Mg, Co and Cd levels were analyzed using atomic absorption spectrophotometric method. Results: Serum Cu and Zn levels were significantly higher, but Mn and Pb levels were lower in patients with PCOS compared with the healthy participants (p < 0.01). There was no difference between patients with PCOS and the controls with respect to the serum levels of Mg, Co and Cd. Conclusions: This is the first study investigating serum Cu, Zn, Mn, Pb, Co, Mg and Cd levels in the patients with PCOS. The serum levels of trace elements and heavy metals might change in patients with PCOS. The findings in this study should be investigated with further trials in order to obtain new insights into PCOS.

Delayed diagnosis of an atypical rupture of an unscarred uterus due to assisted fundal pressure: a case report

IntroductionAlthough rare, rupture of an unscarred uterus is one of the most dangerous obstetric complications, resulting in maternal and fetal jeopardy.Case presentationA 30-year-old grand multiparous Turkish woman without any history of uterine surgery gave birth vaginally at 37 weeks of gestation with fundal pressure applied in the second stage of labor. Transabdominal sonography performed 32 hours after delivery due to postural hypotension and a drop in hemoglobin values in the postpartum period revealed massive intra-abdominal free fluid. On emergency laparotomy, serosal rupture of the uterus on the left posterior side was observed. She underwent a subtotal hysterectomy and did well postoperatively.ConclusionPostural hypotension in postpartum patients without any evident vaginal bleeding may be an early sign of possible uterine rupture, even if the vital signs are stable. Early diagnosis is important if maternal morbidity and mortality are to be decreased.

Side effects and acceptability of Implanon: A pilot study conducted in eastern Turkey.

Objective To assess side effects during the first 6 months of use of Implanon®. Design and methods The study was conducted in eastern Turkey between June 2004 and May 2005. Forty-one healthy women, aged 18–40 years who chose to use Implanon® participated in the study. The implant was inserted between days 1 and 5 of the menstrual cycle. Findings were recorded before and during 6 months following insertion. Statistical analyses were performed using SPSS package programme including paired samples t-test. Results No pregnancy occurred during the study. Ninety days after initiation of therapy, three of the 41 patients (7.3%) had regular periods, 14 (34.1%) were amenorrhoeic and the remaining 24 (58.5%) had some type of abnormal bleeding. Dysmenorrhoea affected significantly less women (1/41, i.e. 2.4%) than before treatment (17/41, i.e. 41.5%), but mastalgia increased significantly as it was reported by five previously unaffected participants (12.2%). Mood changes appeared in seven patients (17.1%) and acne in 11 of them (26.8%). The circulating levels of protein C, total cholesterol and oestradiol dropped significantly. Endometrial thickness decreased significantly. At completion of the study period, removal of the implant was requested by eight of the 41 patients (19.5%) because of irregular bleeding (six women), depressive symptoms requiring treatment (one woman) or weight gain (one woman). Conclusions Mainly because of irregular bleeding, the discontinuation rate of Implanon® at 6 months among the women in this region is high (19.5%).

Eight years' experience of uterine rupture cases.

Summary Ruptured uterus is a serious obstetric emergency with a high maternal and perinatal mortality. It is a preventable and common obstetric problem in developing countries. The objective of this study was to review the incidence, methods of diagnosis and maternal and perinatal morbidity and mortality associated with uterine rupture. Case notes were reviewed for all patients with a ruptured uterus at Yüzüncü Yıl University Medical Faculty Department of Obstetrics and Gynaecology from January 1995 to August 2003. Relevant data relating to the clinical characteristics of labour, operative procedures, maternal and perinatal outcome were assessed. There were 20 cases of ruptured uteri. The incidence was 0.40%. When patients referred from other hospitals were excluded, the revised ratio was 0.12%. There were 13 (65%) complete and seven (35%) incomplete ruptures. Nine (45%) cases occurred in patients with scarred uteri. Ten (50%) cases were grand multiparous. Subtotal abdominal hysterectomy was performed in five (25%) cases, total abdominal hysterectomy was performed in two (10%) cases and the remaining 13 (65%) cases had uterine rupture repair. There were two (10%) maternal deaths. Both of them were referred from other hospitals. There were seven (35%) perinatal deaths attributable to uterine rupture. Occurrence of uterine rupture is significantly associated with grand multiparity, scarred uterus, lack of antenatal care, unsupervised labour at home and low socioeconomic status of the patients. These factors are largely preventable.

Doppler analysis of uterine perfusion and ovarian stromal blood flow in polycystic ovary syndrome

To investigate blood flow velocity in the ovarian stromal artery and uterine artery in women with polycystic ovary syndrome (PCOS) and to correlate these velocities with clinical and biochemical parameters.

Ovarian Stimulation in Obese and Non-Obese Polycystic Ovary Syndrome Using a Low-Dose Step-Up Regimen with Two Different Starting Doses of Recombinant Follicle-Stimulating Hormone

Sixty-seven infertile women with polycystic ovary syndrome (PCOS) were divided into two groups, obese and non-obese, according to their body mass index. Waist-to-hip ratio, insulin resistance, total testosterone and dehydroepiandrosterone sulphate levels were significantly elevated in obese, compared with non-obese, patients. Both groups were treated with a low-dose step-up protocol of recombinant follicle-stimulating hormone (rFSH) with a starting dose of 50 IU/day and, every third day, a 25-IU increase in the dose until the appropriate dose was achieved for each individual, up to a maximum of 175 IU/day. In the obese group only, repeat therapy commenced in the second ovulatory cycle in women who had not become pregnant, however a starting dose of 75 IU/day was then used, with incremental and maximum dose as before. The results of the starting dose of 75 IU/day rFSH were compared with the results of a 50 IU/day rFSH starting dose in the obese group. A starting dose of 50 IU/day rFSH in a low-dose step-up regimen was found to be effective, safe and well-tolerated for inducing follicular development in non-obese infertile women with PCOS. However, for obese PCOS patients, a starting dose of 75 IU/day rFSH is recommended.

The maternal serum thiol/disulfide homeostasis is impaired in pregnancies complicated by idiopathic intrauterine growth restriction

Abstract Purpose: To investigate the maternal serum thiol/disulfide homeostasis in pregnancies complicated by idiopathic intrauterine growth restriction (IUGR) and to compare the results with healthy pregnancies. Materials and methods: This descriptive cohort study included 55 pregnant women complicated by idiopathic IUGR and 57 similar gestational aged healthy pregnant women in the third trimester of gestation. Maternal serum samples were collected at the day of diagnosis and the thiol/disulfide homeostasis was measured by using an automated assay method. The patients were followed up until delivery and perinatal outcomes were recorded. Results: Maternal serum native thiol (308.1 ± 40.7 μmol/L vs. 282.4 ± 60.6 μmol/L) and total thiol (346.8 ± 48.1 μmol/L vs. 324.0 ± 62.2 μmol/L) concentrations were significantly lower in IUGR group compared with healthy controls (p: .010 and p: .032, respectively), whereas disulfide (19.3 ± 8.7 μmol/L vs. 20.8 ± 7.8 μmol/L) concentrations were similar between the groups (p: .350). Maternal serum disulfide/native thiol and disulfide/total thiol ratios were higher in IUGR group compared with healthy controls (p: .014 and p: .017, respectively), whereas native thiol/total thiol ratio was significantly lower in IUGR group compared with healthy controls (p: .016). Conclusions: This study suggests that there is an impaired maternal thiol/disulfide homeostasis in pregnancies complicated by idiopathic IUGR during the third trimester of gestation.
