Serum zonulin level is not elevated in patients with polycystic ovary syndrome without metabolic syndrome.
AIM
Polycystic ovary syndrome (PCOS) is a complex disorder with gynecological, metabolic and carcinogenic effects. Increased intestinal permeability is related with obesity, insulin resistance, type 1 and 2 diabetes mellitus. The existence of such a relationship between PCOS and intestinal permeability has come to an end. Zonulin can change intestinal permeability, and this effect is reversible. We studied the relation between zonulin and the hormonal and metabolic parameters of PCOS.


METHOD
A total of 45 women with PCOS and 17 healthy women were included in the study. Histories were taken from all the participants, body mass indexes were calculated, and biochemical tests and suprapubic over ultrasonography were made. Zonulin was studied with enzyme-linked immunosorbent assay.


RESULTS
Serum zonulin levels were similar between PCOS and control groups (p = 0.893). In all participants, there were negative correlations between zonulin and the total cholesterol, LDL-cholesterol, triglycerides and non-HDL-cholesterol (respectively, p = 0.00, 0.018, 0.004, 0.002), there were boundary correlations with age and total cholesterol/HDL-cholesterol (respectively, p = 0.052 and 0.058). No statistically significant was detected in the PCOS group except negative correlation between zonulin and age (p = 0.046), boundary correlation between zonulin and total cholesterol/HDL-cholesterol (p = 0.064).


CONCLUSION
PCOS patients did not have metabolic syndrome. Zonulin was not higher in PCOS then controls, and it had only negative relation with age. The negative relation between zonulin and some metabolic parameters in all participants was not detected in PCOS group. So zonulin is not a useful molecule for the diagnosis of PCOS without metabolic syndrome.
