Serological markers of autoimmunity ‎in women with polycystic ovary ‎syndrome

In the present study, we evaluate the serum level of common autoimmunologic markers in ‎women with polycystic ovary syndrome (PCOS) and study their relationship with ‎hormonal ‎parameters. The study was ‎an observational case-control study, done in a Tertiary referral hospital, the study ‎included ‎50 women with polycystic ovary syndrome and 50 matched control.‎ Serum levels of Antinuclear Antibody (ANA) and anti-double-stranded DNA (dsDNA) were significantly higher in polycystic ovary ‎syndrome women compared to control. Also, luteinizing hormone (LH), follicle stimulating hormone (FSH), and LH/FSH ratio were ‎significantly higher in polycystic ovary syndrome women compared to control. ‎dsDNA had excellent ability to differentiate PCOS from control (AUC=0.901) while ANA had good discrimination ability ‎‎(AUC=0.809). There was a significant direct relationship between ANA, dsDNA, and TSH ‎with FSH in PCOS women, ‏also a ‎significant direct relationship between ANA and TSH with LH, while ‎DsDNA did not correlate with LH. In conclusion, there is a clear relationship between immunological markers (ANA, dsDNA) with ‎‎polycystic ovary syndrome in various components of the disease, dsDNA offer better ability than ANA as a predictor of PCOS, indicating that dsDNA can be used as a non-invasive diagnostic tool for PCOS.
