Vitamin D and metabolic disturbances in polycystic ovary syndrome (PCOS): A cross-sectional study.

ABSTRACT:

Objective

To compare vitamin D status in women with PCOS versus fertile women and subsequently evaluate the association between vitamin D status and metabolic disturbances in PCOS women.

Methods

We conducted a cross-sectional comparison study of 639 women with PCOS and 449 fertile women. Serum 25-hydroxyvitamin D (25(OH)D) was stratified into a severe deficient (< 25 nmol/l), insufficient (25-50 nmol/l), moderate (50-75 nmol/l) and adequate (> 75 nmol/l) status. The main outcome measures were the difference in vitamin D status between PCOS and fertile women, and the association between serum 25(OH)D and metabolic disturbances in PCOS women only.

Results

Serum 25(OH)D was significantly lower in PCOS women compared to fertile controls (mean 25(OH)D of 49.0 nmol/l versus 64.5 nmol/l). An adjusted significant difference was seen between serum 25(OH)D and homeostasis model assessment (HOMA-IR) (? = 0.76; 95% CI: 0.63-0.91; p < 0.01), HDL-cholesterol (? = 0.20; 95% CI: 0.05-0.60, p < 0.01) and apolipoprotein A1 (? = 26.2; 95% CI: 7.5-45.0, p < 0.01) between the highest vitamin D group compared to the lowest vitamin D group.

Conclusions

This study demonstrates that women with PCOS have a significantly lower serum 25(OH)D compared to fertile controls. A compromised vitamin D status in PCOS women is associated with a higher HOMA-IR and an unfavourable lipid profile. Large randomized controlled trials are necessary to explore the causality of this linkage.

Project description:<p><b>PCOS</b> is a complex genetic disease reflecting the interplay of susceptibility genes and environmental factors. The cardinal reproductive feature of the syndrome, hyperandrogenemia, appears to play a direct role in the pathogenesis of the associated metabolic abnormalities. Male as well as female first-degree relatives have reproductive and metabolic phenotypes including increased prevalence rates of type 2 diabetes (T2D), metabolic syndrome (MBS) and other risk factors for cardiovascular disease (CVD). Northwestern University (NU) investigators lead a team that has extensive experience in phenotyping PCOS and in the genetic analysis of complex diseases including genome-wide association study (GWAS). Together with an expert group of collaborators from the Hershey Medical Center, and The University of Chicago, we have conducted a GWAS to identify PCOS susceptibility alleles using a large cohort of extensively and consistently phenotyped PCOS cases. Population controls for this study come from the NUgene project described below.</p> <p><b>NUgene project</b>: In 2002, Northwestern committed to the development of a DNA repository to serve as a platform for the identification and validation of genotype-phenotype associations that will impact healthcare. The NUgene Project is a repository with longitudinal medical information from participating patients at affiliated hospitals and outpatient clinics from the Northwestern University Medical Center. Participants' DNA samples are coupled with data from a questionnaire (2 versions were used, 1 before and 1 after February 2006, both are included) and continuously updated data from our Electronic Medical Record (EMR) representing actual clinical care events. Northwestern has a state-of-the art, comprehensive inpatient and outpatient EMR system of over 2 million patients. NUgene has broad access to participant data for all outpatient visits as well as inpatient data via a consolidated data warehouse. NUgene participants consent to distribution and use of their coded DNA samples and data for a broad range of genetic research by third-party investigators.</p>

Project description:OBJECTIVES:Polycystic ovary syndrome (PCOS) is the most common endocrinopathy of women at reproductive age. Although the aetiology of PCOS remains unclear, potential effects of environmental endocrine-disrupting compounds on the development of PCOS have drawn increasing attention. The aim of the current study was to examine the association between triclosan (TCS) and PCOS, and explore possible mechanisms on how TCS may contribute to the development of clinical manifestations of PCOS. DESIGN:Cross-sectional study. SETTING:This study was conducted in one tertiary-level hospital located in Zhejiang, China. PARTICIPANTS:A total of 674 infertile women at 18-45 years of age were recruited in 2014-2015. Participants with (n=84) and without (n=212) PCOS with urinary TCS concentration available were included in the analyses. METHODS:Urinary TCS concentration was measured using a high-performance liquid chromatography-electrospray ionisation tandem mass spectrometry. Logistic regression model was used to examine the association between TCS and PCOS. Fractional polynomial regression models were built to fit the potential non-linear relationship between TCS concentrations and luteinising hormone (LH) and LH/follicle stimulate hormone (FSH). RESULTS:The PCOS group had significantly higher level of TCS concentration than the non-PCOS group (the median of TCS (IQR), ?g/g creatinine: 1.49 (0.68-3.80) vs 1.06 (0.52-3.02), p=0.0407). Compared with the lowest tertile, the highest tertile of TCS concentration was associated with an increased odd of PCOS (OR 2.12, 95% CI 1.12 to 3.99). After adjusting for potential confounders, the significant association remained (OR 1.99, 95%?CI 1.05 to 3.79). Positive relationships were found between TCS levels and LH and LH/FSH ratio in non-PCOS participants. CONCLUSIONS:TCS exposure at a relatively low level is associated with PCOS in Chinese women. Further epidemiological studies are needed to confirm our finding, which may have important public health implications.

Project description:BackgroundThis study was undertaken to explore the treatment-seeking pathways traversed by women with PCOS and elicit their behavior, experiences and perspectives regarding it.MethodsThis concurrent mixed-method study was conducted on 18-40 years old women diagnosed with PCOS at the Gynecology outpatient department, PGIMER, Chandigarh, India. Of the 275 women, who were administered a questionnaire to elicit their treatment-seeking behavior, 62 willing participants were subjected to in-depth interviews. Quantitative responses were descriptively analyzed and presented as count, proportion, mean or median. Framework analysis was performed for the qualitative data. The findings of both types of data were triangulated to construct the pathways to treatment traversed by PCOS patients.FindingsMany (~45%) respondents had no information regarding PCOS. Only 9.1% received some information from their doctors. Though the internet was the primary source of information for 37.5% of respondents, they expressed dissatisfaction with the quality of information. Multiple health care agencies were consulted by most (85.8%) of the respondents. Allopathy was the preferred choice of treatment. The average delay in initiating the treatment was 3 months. The major reasons for this were ignorance, the concept of 'normality' and 'endurance'. Deviations from the normal self (like irregular-menstruation, obesity, hirsutism, infertility) were the concern that led them to consult a doctor. They were also dissatisfied with the treatment due to a late diagnosis, lack of relief, taboo, side-effects, expenses involved and the need for repeated laboratory tests. Participants' course of treatment was influenced by the interplay of individual, distress, health-system, and social-economic factors.ConclusionsWomen with PCOS were dissatisfied with the quality of the information and treatment received. There were treatment delays. The patients consulted multiple health agencies, including indigenous therapies, in the hope of relief. The findings provide an empirical basis on points to focus on for building better coping strategies for managing the condition.
