ContextMetabolic disturbances, in particular, insulin resistance (IR) and dyslipidemia, are common in women suffering from polycystic ovary syndrome (PCOS). Evidence is accumulating that vitamin D status may contribute to the development of metabolic disturbances in PCOS.ObjectiveThe aim of this study was to carry out a systematic review addressing the association between vitamin D status, vitamin D receptor polymorphisms, and/or polymorphisms related to vitamin D metabolism and metabolic disturbances in women with PCOS.Design and methodsA systematic search of electronic databases was carried out up to January 2013 for observational studies and clinical trials in women suffering from PCOS with outcome measures that were related to vitamin D status. We conducted univariate and multivariate regression analyses of the weighted means to gain insights into the association between vitamin D, BMI, and IR based on existing literature.ResultsWe found 29 eligible trials with inconsistency in their results. One well-designed randomized controlled trial has been carried out until now. Univariate regression analyses of the weighted means revealed vitamin D to be a significant and independent predictor of IR in both PCOS and control women. The significance disappeared after adjustment for BMI in PCOS women.ConclusionsCurrent evidence suggests an inverse association between vitamin D status and metabolic disturbances in PCOS. Owing to the heterogeneity of the studies, it is hard to draw a definite conclusion. The causal relationship between vitamin D status and metabolic disturbances in PCOS remains to be determined in well-designed placebo-controlled randomized clinical trials.

Metabolic Biomarkers

Polycystic ovary syndrome (PCOS) one of the most common endocrine disorders in women of reproductive age, the pathogenesis of PCOS imitated to be as a vicious cycle involving both hyperandrogenaemia and insulin resistance/hyperinsulinemia. Vitamin D deficiency (VDD) is common among women with PCOS (approximately 67%–85% women with PCOS have VDD). Vitamin D3 and CoQ10 could affect glucose metabolism and insulin sensitivity and improve metabolic abnormalities in PCOS. The study was designed to evaluate the effect of combining oral vitamin D3 tablet or CoQ10 capsule with clomiphene citrate on metabolic biomarkers in women with clomiphene citrate resistance PCOS patients. A prospective interventional randomized-controlled, open-label study include 41 PCOS patients aged range (18-34)years who are clomiphene citrate resistant divided into two groups, group 1 (n=24) whose endogenous vitamin D status less than 20ng/ml receive clomiphene citrate 100mg daily(for 5 days monthly induction) plus vitamin D 10000IU daily (2 months) and group 2 (n=17) whose endogenous vitamin D status equal or more than 20ng/ml receive clomiphene citrate 100mg daily(for 5 days monthly induction) plus CoQ10 200mg daily (2 months). Fasting blood samples were taken at baseline and 2 months after intervention to measure metabolic biomarkers [fasting serum insulin (FSI), fasting blood glucose (FBG), homeostatic model assessment of insulin resistance (HOMA-IR), quantitative insulin sensitivity check index (QUICKI)]. After 2 months both interventions result in non-significant change in FSI and FBG while HOMA-IR and QUICKI decreased by both interventions, but the decrease is significant only with CoQ10 supplementations. In conclusion, Vitamin D and CoQ10 supplementation result in improvement in HOMA-IR and QUICKI but the improvement was more obvious in CoQ10 group.

Beneficial Role

Abstract. Vitamin D is a secosteroid hormone that plays a pivotal role in several metabolic and reproductive pathways in humans. Increasing evidence supports the role of vitamin D deficiency in metabolic disturbances and infertility in women with polycystic ovary syndrome (PCOS). Indeed, supplementation with vitamin D seems to have a beneficial role on insulin resistance and endometrial receptivity. On the other hand, exceedingly high levels of vitamin D appear to play a detrimental role on oocytes development and embryo quality. In the current review, we summarize the available evidence about the topic, aiming to suggest the best supplementation strategy in women with PCOS or, more generally, in those with metabolic disturbances and infertility. Based on the retrieved data, vitamin D seems to have a beneficial role on IR, insulin sensitivity and endometrial receptivity, but high levels and incorrect timing of administration seem to have a detrimental role on oocytes development and embryo quality. Therefore, we encourage a low dose supplementation (400–800 IU/day) particularly in vitamin D deficient women that present metabolic disturbances like PCOS. As far as the reproductive health, we advise vitamin D supplementation in selected populations, only during specific moments of the ovarian cycle, to support the luteal phase. However, ambiguities about dosage and timing of the supplementation still emerge from the clinical studies published to date and further studies are required.
