Five to ten percent of women of reproductive age suffer from polycystic ovary syndrome (PCOS). Leptin, NPY, galanin, cholecystokinin (CCK) are involved in the regulation of eating behavior. PPAR gamma are receptors that are probably involved in hyperandrogenism. This study was designed to assess associations between the Pro12Ala PPAR gamma 2 gene polymorphism and satiety factors in PCOS. Fifty-four PCOS women and 51 healthy women were studied. Leptin, NPY, galanin, CCK levels, and genetic studies to detect Pro12Ala PPAR gamma 2 gene polymorphism were assessed. The leptin levels in the PCOS women carrying Pro12Ala genotype were higher than in those with Pro12Pro and Ala12Ala. The PCOS women had higher leptin and NPY levels and lower galanin levels. Obese PCOS patients had lower CCK levels. Conclusions: In the PCOS women, a single Ala allele may have a protective role as far as hyperleptinemia is concerned. The PCOS women may reveal a disrupted central leptin/NPY feedback loop with some shifts in food intake.
