Objective:
To observe the changes in urine albumin (UALB), von Willebrand factor (vWF) and platelet-activating factor (PAF) in different courses of type 2 diabetes.
Methods:
Levels of UALB, vWF and PAF were determined in 30 type 2 diabetic nephropathy patients(group A), type 2 diabetic patients without DNP(group B, n=30), patients with impaired glucose tolerance (group C, n=30), the first-degree relatives of type 2 diabetic patients with normal glucose tolerance(group D, n=30) and 30 normal glucose tolerance subjects without family history of type 2 diabetes(group E).
Results:
UALB and PAF contents were significantly higher in group A than in the other groups (P<0.01), while between the latter 4 groups, the contents showed no significant differences (P>0.05). Serum vWF level was significantly higher in group A than those in the other groups (P<0.05).
Conclusions:
Renal dysfunction and platelet activation are present in type 2 diabetes with microvascular complications, and the synchronized changes between renal dysfunction and platelet activation indicate the involvement of elevated PAF in vascular injury.
