Association of Arachidonic Acid, Eicosapentaenoic Acid and Serum Amyloid A Levels in Women with PCOS

Background Objective: PCOS is a multifactorial disorder characterized by inflammation caused by unknown reasons. This study aimed to investigate the Arachidonic acid (AA), eicosapentaenoic acid (EPA) levels and Serum amyloid A (SAA) protein and gene expression of follicular fluid in women with PCOS. Materials Methods: The study included 30 PCOS and 30 healthy women. The individuals were selected after clinical examination and the inclusion criteria. During the puncture and after removing oocytes, follicular fluids were collected from individuals. The SAA protein concentration was determined by the ELISA method. Arachidonic acid, eicosapentaenoic acid levels were determined using GC method and the statistical software SPSS 16, and the p value less than 0.05 was considered as significant. Results: There was a significant difference in metaphase II oocytes (M2) (p =0.001), number of Embryo (p =0.014), Estradiol (p =0.025), FSH (0.040), LH (p =0.035) and Prolactin (p =0.023) levels between two groups. The concentration of SAA protein level and gene expression shows a significant increase in the patient group compared to the control group (p 0.05). The results showed that AA level was significantly increased in the patient group (284.12 ng/mL) compared to the control group (176.23 ng/mL) (p =0.001) while, there was a significant decrease (p =0.001) in EPA level in the patient group (24.56 ng/mL) compared to the control group (33.48 ng/mL). Conclusion: It appears that higher EPA levels and lower follicular fluid AA concentrations reduce SAA levels and thus may increase follicular maturation in women with PCOS.
