Impaired fibrinolytic activity in type II diabetes: Correlation with urinary albumin excretion and progression of renal disease

Progression of renal disease and cardiovascular complications in type II diabetes mellitus have been shown to correlate with control of blood glucose, lipids, blood pressure, and smoking. These factors, however, do not appear to totally explain these diabetic complications. Renal disease and cardiovascular complications in type II diabetes are associated with vascular abnormalities and fibrosis, both of which may occur with impaired fibrinolysis. A cross-sectional study was therefore performed in 107 type II diabetic patients recruited from the Denver Metropolitan Area to examine the effect of impaired fibrinolysis, as assessed by the ratio of plasminogen activator inhibitor (PAI-1) to tissue-type plasminogen activator (t-PA). With urinary albumin excretion (UAE) as a risk factor for both renal disease progression and cardiovascular complications, the patients were analyzed with respect to UAE less than and greater than 1 gm/day. The age, blood glucose, hemoglobin A1C, duration of diabetes, lipids, body mass index, and smoking were no different between the groups. As expected, the group with greater UAE had worse renal function, the serum creatinine (1.98±0.24 vs 1.21±0.05 mg/dl, P P P P
