Increased serum neopterin levels in women with polycystic ovary syndrome

Polycystic ovary syndrome (PCOS) occurs in 5-10% of premenopausal women. Studies suggest that PCOS is associated with increased risk of coronary heart disease (CHD). To investigate this relationship, 15 PCOS women (group 1) and 10 healthy women (group 2) were studied. Blood leukocyte counts (white blood cells, WBC) and serum levels of total cholesterol, HDL-cholesterol, LDL-cholesterol, sensitive C-reactive protein (sCRP), and neopterin were measured in the 2 groups. There were no significant differences in serum total cholesterol, HDL-cholesterol, or LDL-cholesterol concentrations between groups 1 and 2. Blood WBC counts and serum levels of neopterin and sCRP were significantly higher in group 1 than group 2. The median (min-max) levels were: WBC, group 1: 8.05 (5.10-9.70) cells x 10(9)/L, group 2: 6.25 (4.70-9.70) cells x 10(9)/L (p
