Significant Improvement Selected Mediators of Inflammation in Phenotypes of Women with PCOS after Reduction and Low GI Diet

Abstract EN

Many researchers suggest an increased risk of atherosclerosis in women with polycystic ovary syndrome.

In the available literature, there are no studies on the mediators of inflammation in women with PCOS, especially after dietary intervention.

Eicosanoids (HETE and HODE) were compared between the biochemical phenotypes of women with PCOS (normal and high androgens) and after the 3-month reduction diet.

Eicosanoid profiles (9(S)-HODE, 13(S)-HODE, 5(S)-HETE, 12(S)-HETE, 15(S)-HETE, 5(S)-oxoETE, 16(R)-HETE, 16(S)-HETE and 5(S), 6(R)-lipoxin A4, 5(S), 6(R), 15(R)-lipoxin A4) were extracted from 0.5 ml of plasma using solid-phase extraction RP-18 SPE columns.

The HPLC separations were performed on a 1260 liquid chromatograph.

No significant differences were found in the concentration of analysed eicosanoids in phenotypes of women with PCOS.

These women, however, have significantly lower concentration of inflammatory mediators than potentially healthy women from the control group.

Dietary intervention leads to a significant (p<0.01) increase in the synthesis of proinflammatory mediators, reaching similar levels as in the control group.

The development of inflammatory reaction in both phenotypes of women with PCOS is similar.

The pathways for synthesis of proinflammatory mediators in women with PCOS are dormant, but can be stimulated through a reduction diet.

Three-month period of lifestyle change may be too short to stimulate the pathways inhibiting inflammatory process.
