Abstract

OBJECTIVES:

To investigate the haemostatic parameters and to assesss their relationship with microvascular complications in type 2 diabetes mellitus.

MATERIALS AND METHODS:

Coagulation and fibrinolysis parameters were measured in 60 type 2 diabetic patients (M:F 1:1) with (n=40) and without (n=20) diabetic microvascular complications and in 30 nondiabetic healthy subjects (M:F 1:1).

RESULTS:

The mean age of diabetic patients and healthy controls was 56.9 +/- 8.78 and 53.2 +/- 7.58 respectively (p = 0.05). The plasma levels of PAI-1 (22.6 +/- 6.85 vs 44.8 +/- 20.8, p = 0.00), serum fibrinogen (227.5 +/- 22.8 vs. 252.75 +/- 40.23, p = 0.002) and vWF activity (99.4 +/- 28.18 vs. 144.78 +/- 36.21, p = 0.00) were found to be increased in diabetics compared to healthy controls. Plasma PAI-1 levels (37.15 +/- 15.18 vs 48.65 +/- 22.29, p = 0.0) and vWF activity (123.19 +/- 29.63 vs. 155.57 +/- 34.61, p = 0.007) were significantly increased in diabetic patients with microvascular complications than those without microvascular complications.Amongst the diabetic patients, protein S activity (63.05 +/- 16.85 vs. 51.59 +/- 10.7, p = 0.002) was significantly lower in patients with microvascular complications than in patients without these complications. Diabetic retinopathy was associated with decreased protein S levels (63.05 +/- 16.85 vs. 48.48 +/- 8.72, p = 0.005) and vWF activity (123.19 +/- 29.63 vs. 151.85 +/- 29.74, p = 0.009). Diabetic nephropathy was associated with increased PAI-1 levels (39.55 +/- 13.20 vs. 51.69 +/- 26.53, p = 0.02) and vWF activity (134.99 +/- 32.54 vs. 157.57 +/- 37.37, p = 0.007). Diabetic neuropathy did not show any significant relationship with any of the haemostatic variables.

CONCLUSION:

Hypercoagulable state as indicated by decreased fibrinolysis and increased coagulability is responsible as one of the factors for the development of microvascular complications of diabetes mellitus.
