Abstract [en]

Background: Previous studies have indicated that peripheral circulating markers of inflammation are elevated in women with polycystic ovary syndrome (PCOS), but thus far no studies concerning markers of inflammation in adipose tissue have been published. The aim of the study was to investigate whether patients with PCOS display increased expression of inflammatory markers in adipose tissue.

Methods: Twenty overweight patients with PCOS, 10 lean patients with PCOS and 20 overweight controls had subcutaneous fat biopsies and blood samples taken. Adipose tissue levels of mRNA of inflammatory markers were determined by use of real-time PCR.

Results: Overweight patients with PCOS had higher relative adipose tissue chemokine ligand 2 (P < 0.01), and its cognate receptor (P < 0.05), tumour necrosis factor-alpha (P < 0.001), interleukin (IL)-10 (P < 0.001) and IL-18 (P < 0.001) and the monocyte/ macrophage markers CD14 (P < 0.01) and CD163 (P < 0.01) mRNA levels compared with lean women with PCOS. There were no differences between overweight patients with PCOS and overweight control subjects in this respect. Within the PCOS group, markers of adipose tissue inflammation correlated significantly with obesity-related metabolic disturbances, but when data were adjusted for age and BMI, most correlations were lost.

Conclusions: Overweight, rather than the PCOS diagnosis per se, appears to be the main explanatory variable for elevated adipose tissue inflammation in patients with PCOS.
