- OBJECTIVE: To examine the efficacy of sibutramine together with brief lifestyle modification for weight reduction in obese women with polycystic ovary syndrome (PCOS). DESIGN: Investigator-initiated, multicenter, double-blind, randomized, parallel-group clinical trial. SETTING: Departments of Obstetrics and Gynecology in primary care, referral centers, and private practice. PATIENT(S): Forty-two patients with confirmed PCOS were included in the study, and 34 patients completed the study. INTERVENTION: Sibutramine 15 mg once daily together with brief lifestyle modification was compare with placebo together with brief lifestyle modification. MAIN OUTCOME MEASURE(S): The primary endpoint was to assess weight loss. Secondary endpoints included the efficacy of sibutramine for treatment of menstrual pattern and cardiovascular risk factors. RESULT(S): After 6 months the sibutramine group had lost 7.8 +/- 5.1 kg compared with a weight loss of 2.8 +/- 6.2 kg in the placebo group. Sibutramine treatment resulted in significant decreases in apolipoprotein B, apolipoprotein B/apolipoprotein A ratio, triglycerides, and cystatin C levels. CONCLUSION(S): Sibutramine in combination with lifestyle intervention results in significant weight reduction in obese patients with PCOS. In addition to the weight loss, sibutramine seems to have beneficial effects on metabolic and cardiovascular risk factors.

- INTRODUCTION: Women with spontaneous preterm birth have an increased risk of cardiovascular disease later in life. Studies suggest potential pathophysiological mechanisms in common, but whether these could be identified by measurement of soluble circulating protein biomarkers in women with spontaneous preterm birth is unknown. The aim of this study was to determine if protein biomarkers associated with cardiovascular disease distinguish women with spontaneous preterm birth from healthy controls, both at pregnancy and at follow up.MATERIAL AND METHODS: Study participants were identified in the population-based Uppsala biobank of pregnant women in Sweden, where plasma samples were collected in mid-pregnancy. In a first screening phase, we identified participants who subsequently experienced spontaneous preterm birth (<37 weeks) in the index pregnancy (N = 13) and controls (N = 6). In these samples, differences in protein expression were examined by comparative mass spectrometry. In a second validation phase, we invited 100 cases with previous spontaneous preterm birth in the index pregnancy and 100 controls (matched for age, body mass index, and year of delivery) from the same source population, to a follow-up visit 4-15 years after pregnancy. At follow up, we collected plasma samples and data on cardiovascular risk factors. We measured concentrations of selected biomarkers identified in the screening phase, as well as lipid profiles in samples both from pregnancy (biobank) and follow up.CLINICALTRIALS: gov registration NCT05693285.RESULTS: In the screening phase, fibrinogen, cadherin-5, complement C5, factor XII, plasma kallikrein, apolipoprotein M, and vitamin D-binding protein differed significantly at pregnancy. In the validation phase, 65 women agreed to participate (35 cases and 30 controls), with a median follow-up time of 11.8 years since pregnancy. The concentration of fibrinogen (p = 0.02) and triglycerides (p = 0.03) were slightly higher in cases compared with matched controls at follow up.CONCLUSIONS: Compared with women without preterm birth, those with spontaneous preterm birth had slightly higher concentrations of fibrinogen, both at mid-pregnancy and a decade after pregnancy. Additionally, we found slightly higher concentration of triglycerides at follow up in women with previous spontaneous preterm birth. The relevance of this finding is uncertain but might indicate potential pathophysiological mechanisms in common between spontaneous preterm birth and cardiovascular disease.

- OBJECTIVEAdipocytokines participate in the regulation of glucose metabolism and foetal development. The transcription factor activating protein 2B (TFAP2β) has been associated with adipocytokine regulation, and gene variations with type 2 diabetes and obesity. This study investigated associations between maternal TFAP2B variation, adipocytokines levels and maternal and neonatal anthropometric characteristics.DESIGN AND METHODSA population-based sample of women was followed from delivery to six months postpartum. Adiponectin, leptin and interleukin-6 levels at delivery, and maternal as well as neonatal anthropometric variables were assessed. The TFAP2β intron 1 variable number tandem repeat (VNTR) was genotyped.RESULTSMaternal interleukin-6 correlated positively with leptin at delivery, with peripartum weight changes and weight of newborn males, adjusted for potential confounders. Leptin at delivery was associated with TFAP2β intron 1 VNTR genotype, adjusted for confounders, maternal weight and negatively with birth weight among female neonates. A path model suggested a link between TFAP2β genotype, leptin levels and newborn females' weight.CONCLUSIONSThe present results stress a role for the TFAP2 β in adiposity-related conditions and intrauterine growth. The association between neonatal birth weight and maternal adipocytokine levels, together with the observed sex effect, call for further studies on the mechanisms behind neuro-endocrine foetal programming.

- Thirty-four women with polycystic ovary syndrome who previously had participated in studies with intravenous glucose tolerance test and hyperinsulinemic, euglycemic clamp between 1987 and 1995 underwent anthropometric, endocrine (T and sex-hormone binding globulin serum concentration), and metabolic (intravenous glucose tolerance test, hyperinsulinemic, euglycemic clamp, and androgens) measurements. Free androgen levels and β-cell function decreased over time in women with polycystic ovary syndrome, but insulin sensitivity remained unaltered.

- Background: The overall risk of developing diabetes mellitus and glucose intolerance seems to be higher in women with polycystic ovary syndrome (PCOS) than in healthy women. The aim of this long-term follow-up study was to examine glucose tolerance and insulin sensitivity in middle-aged women previously diagnosed with PCOS in comparison with age-matched healthy controls. Methods: Women diagnosed with PCOS between 1987 and 1995 were invited to participate in the study. A total of 84 PCOS patients and 87 control subjects participated. Anthropometric (BMI, waist/hip ratio) and metabolic parameters (oral glucose tolerance test) were measured. Insulin sensitivity was expressed by the Matsuda index and beta cell function by the insulinogenic index. PCOS women were sub-grouped according to phenotype at the index assessment (with or without hyperandrogenism) and persistence of PCOS symptoms at the follow-up (persisting or resolved PCOS). Results: Eighteen (21.4%) PCOS patients and four (4.5%) controls had developed type 1 or type 2 diabetes or impaired glucose tolerance (IGT) at the follow-up investigation (P < 0.05). Matsuda insulin sensitivity index was lower and the insulinogenic index was increased in women with previously diagnosed PCOS compared with control subjects. In addition, PCOS patients with or without hyperandrogenism, and PCOS patients with persisting and resolved PCOS all had lower Matsuda insulin sensitivity index and increased insulinogenic index in comparison with controls. Conclusions: IGT and type 2 diabetes occurred more often in PCOS patients. Independent on PCOS phenotype at index assessment and persistence of PCOS symptoms at the follow-up investigation, women with PCOS had lower insulin sensitivity but a well-preserved beta cell function in comparison with control subjects.

- Background: The aim of this long-term follow-up study was to examine glucose tolerance and insulin sensitivity in middle-aged women previously diagnosed with PCOS in comparison with age-matched healthy controls. Methods: Women diagnosed with PCOS between 1987 and 1995 were invited for the study. 84 PCOS patients and 87 control subjects, randomly selected from the general population, participated in the study. Anthropometric and metabolic parameters, including an oral glucose tolerance test, were examined. Results: Eighteen (21.4 %) PCOS patients had type 1 or type 2 diabetes or impaired glucose tolerance at the follow-up investigation, which was significantly more common than in control subjects (4.5 %), p < 0.05. Following the adjustment for BMI, insulin sensitivity measured by the Matsuda insulin sensitivity index was significantly lower in women with PCOS and the insulinogenic index, as a measure of beta-cell function, was elevated in PCOS patients in comparison to control subjects. Furthermore, both women with persisting and resolved PCOS at the follow-up investigation displayed decreased Matsuda insulin sensitivity index and increased insulinogenic index in comparison with control subjects. Women without clinical signs of hyperandrogenism at the index assessment displayed higher fasting insulin and proinsulin plasma concentrations than controls at the follow-up investigation. In addition, they had lower Matsuda insulin sensitivity index and higher insulinogenic index than controls. When adjusted for BMI, there was also a trend towards significantly lower Matsuda insulin sensitivity index and increased insulinogenic index at the follow-up investigation among women who had presented with hyperandrogenism at the index assessment. Conclusion: IGT and type 2 diabetes occurred more often in PCOS patients. Independent of PCOS phenotype at index assessment and persistence of PCOS symptoms at the follow-up investigation, women with PCOS had lower insulin sensitivity and increased beta-cell function in comparison with control subjects.

Tidskriftsartikel (refereegranskat)abstract
- This study aimed to evaluate the association of maternal adiponectin with infant birth size in 1349 pregnant women at Uppsala University Hospital, Sweden. The mean age of the women was 31.0 years, and 40.9% were nulliparous. Maternal early mid-pregnancy adiponectin was measured in microgram/mL. Linear regression models were performed to evaluate the association between adiponectin and infant birth weight. Logistic regression models were used to evaluate adiponectin in relation to the odds of giving birth to an infant large-for-gestational-age (LGA, infant birth weight standard deviation score > 90th percentile). Adjustments were made for early pregnancy BMI and diabetes mellitus. Prior adjustments, adiponectin was inversely associated with infant birth weight (β - 17.1, 95% confidence interval (CI) - 26.8 to - 7.4 g, P < 0.001), and one microgram/mL increase in adiponectin was associated with a 9% decrease in the odds of giving birth to an LGA infant (odds ratio 0.91, CI 0.85-0.97, P = 0.006). The associations did not withstand in the adjusted models. We found a significant interaction between adiponectin and infant sex on birth size. This interaction was driven by an inverse association between maternal adiponectin and birth size in female infants, whereas no such association was found in males.

- Background: Cerebral complications contribute substantially to mortality in preeclampsia. Pregnancy calls for extensive maternal adaptations, some associated with increased propensity for seizures, but the pathophysiology behind the eclamptic seizures is not fully understood. Plasma osmolality and sodium levels are lowered in pregnancy. This could result in extrusion of cerebral organic osmolytes, including the excitatory neurotransmitter glutamate, but this remains to be determined. The hypothesis of this study was that cerebral levels of organic osmolytes are decreased during pregnancy, and that this decrease is even more pronounced in women with preeclampsia.Method: We used proton magnetic resonance spectroscopy to compare levels of cerebral organic osmolytes, in women with preeclampsia (n=30), normal pregnancy (n=32) and non-pregnant controls (n=16). Cerebral levels organic osmolytes were further correlated to plasma osmolality, and plasma levels of glutamate and sodium.Results: Compared to non-pregnant women, women with normal pregnancy and preeclampsia had lower levels of the cerebral osmolytes myo-inositol, choline and creatine (p=0.001 or less), and all these metabolites correlated with each other (p<0.05). Women with normal pregnancies and preeclampsia had similar levels of osmolytes, except for glutamate, which was significantly lower in preeclampsia. Cerebral and plasma glutamate levels were negatively correlated with each other (p<0.008), and cerebral myo-inositol, choline and creatine levels were all positively correlated with both plasma osmolality and sodium levels (p<0.05).Conclusion: Our results indicate that pregnancy is associated with extrusion of cerebral organic osmolytes. This includes the excitatory neurotransmitter glutamate, which may be involved in the pathophysiology of seizures in preeclampsia.

- INTRODUCTION: Obesity-associated adverse obstetric outcomes are well-known but still relatively rare and difficult to predict. Not all obese individuals are unhealthy, some have metabolically healthy obesity (MHO) and others have metabolic unhealthy obesity (MUO). Our aim was to investigate if the MHO and MUO classification could be used for prediction of obesity-associated complications in pregnancy.MATERIAL AND METHODS: We included 547 pregnant women with obesity, 2302 pregnant women with overweight, and 5852 normal weight pregnant women. The women with obesity were classified as MUO (n = 181, 33.1%) and MHO (n = 366, 66.9%) based on first trimester blood pressure, lipoprotein levels and non-fasting glucose levels. The risk of obstetric outcomes was evaluated by multivariable logistic regression. We compared cardiovascular risk markers in blood between obese pregnant women with MUO and MHO.RESULTS: Overall, 45.9% of women with MUO developed at least one adverse obesity-associated obstetric outcome, whereas corresponding proportions in women with MHO, overweight and normal weight were 35.0%, 27.6% and 21.2%, respectively. Following adjustment, the overall risk of at least one obesity-associated obstetric or perinatal complication in women with MUO, versus women with MHO, was increased, AOR 1.49 (95% CI 1.03 - 2.15), but the predictive value of the model was low. Women with MUO had altered levels of cardiovascular risk markers such as cathepsin S, adiponectin, and cystatin C in comparison to women with MHO.CONCLUSIONS: Women with MUO had an overall increased risk of adverse obstetric outcomes in comparison to women with MHO, but the classification had little relevance for risk prediction beyond that of body mass index.

- Although postpartum depression (PPD) is a common condition, it often goes undiagnosed and untreated, with devastating consequences for the woman's ability to perform daily activities, to bond with her infant and to relate to the infant's father. Leptin, a protein synthesised in the adipose tissue and involved in regulation of food intake and energy expenditure has been related to depressive disorders, but studies report conflicting results. The aim of this study was to evaluate the association between serum leptin levels at the time of delivery and the subsequent development of postpartum depression in women, using data from a population-based cohort of delivering women in Uppsala, Sweden. Three hundred and forty seven women from which serum was obtained at the time of delivery filled out at least one of three structured questionnaires containing the Edinburgh Scale for Postnatal Depression (EPDS) at five days, six weeks and six months after delivery. Mean leptin levels at delivery did not significantly differ between the 67 cases of PPD and the 280 controls. Using linear regression analysis and adjusting for maternal age, body-mass index, smoking, interleukin-6 levels, duration of gestation and gender of the newborn, the EPDS scores at six weeks and six months after delivery were found to be negatively associated with leptin levels at delivery (p<0.05). Serum leptin levels at delivery were found to be negatively associated with self-reported depression during the first six months after delivery. No such association was found concerning serum IL-6 levels at delivery. If these finding are replicated by other studies, leptin levels at delivery could eventually serve as a biological marker for the prediction of postpartum depression.
