Vitamin D and Lipid Profiles in Infertile PCOS and Non-PCOS Females.

Abstract

This research is aimed to explore the relationship between vitamin D and lipid profile in females with PCOS and non-PCOS infertile female subjects. Comparative descriptive study. Place and Duration of the Study: Department of Biological and Biomedical Sciences, The Aga Khan University, Karachi, Pakistan and Jinnah Postgraduate Medical Centre, Karachi, Pakistan in collaboration with the Australian Concept Infertility Medical Centre, from February 2021 to March 2023. A total of 180 infertile women with 120 PCOS and 60 non-PCOS were enrolled. The lipid profile and BMI of the patients were acquired from desk records, and vitamin D was estimated by enzyme-linked immunosorbent assay (ELISA). Participants were classified according to their vitamin D levels as sufficient (30-100 ng/ml), insufficient (20-29 ng/ml), or deficient (below 20 ng/ml). Median, interquartile range, frequency, and percentages were described. Statistical significance was calculated by Mann-Whitney U and Chi-square tests with p-values of 0.05. Females with PCOS had significantly low vitamin D (p <0.001). Total cholesterol, low-density lipoprotein, very low-density lipoprotein, and triglyceride levels were significantly increased, and high-density lipoprotein cholesterol (HDL) was less in comparison to the non-PCOS group (p <0.001). A significant increase in total cholesterol, triglycerides, low-density lipoproteins, and very low-density lipoproteins was found in the vitamin D deficient subgroup compared with insufficient or sufficient groups (p = 0.05). The study provides a link between females with PCOS and abnormalities in lipid profile. Decreased vitamin D levels in females with PCOS were linked with an abnormal lipid profile characterised by rise in cholesterol, triglycerides, and low-density lipoproteins which may lead to metabolic abnormalities.
