Absence of profound hyperinsulinism in polycystic ovary syndrome is associated with subtle elevations in the plasminogen activator inhibitor system
2003
In order to describe potential hypofibrinolytic tendencies in young (< 35 years) polycystic ovary syndrome (PCOS) patients ,we studied plasminogen activator inhibitor (PAI-1) system components in women without laboratory evidence of hyperinsulinism or hyperandrogenism. The study was a prospective ,observational comparison and took place in a major urban infertility referral center. Age ,body mass index, ovulatory status ,selected androgen levels ,fasting insulin and plasma lipids were measured in subjects with PCOS (n = 39) and normal control subjects (n = 20). Women with PCOS had higher mean serum total testosterone and androstenedione levels compared with controls (56.4 versus 40.3 ng/dl ,p = 0.03 ,and 179 versus 133 μg/ml ,p = 0.03 ,respectively). Mean fasting insulin levels were higher among PCOS women (p < 0.01) and were strongly correlated with PAI-1 antigen (Ag) (r = 0.46) ,PAI-1 activity (r = 0.43) ,and tissue plasminogen activator (t-PA) (r = 0.5). Correlations were evident in both PCOS and contr...
