In microalbuminuria there is an increased cardiovascular risk not fully explained by the excess of conventional risk factors. To investigate whether or not microalbuminuria is associated with haemostatic abnormalities in Type 2 diabetic patients, we measured the prothrombin fragment 1 + 2, a marker of thrombin generation, and the thrombin‐antithrombin complex, a marker of thrombin neutralization. Plasma levels of prothrombin fragment 1 + 2 and thrombin‐antithrombin complex were assayed in 17 microalbuminuric patients (albumin excretion rate, AER 20–200 μg min −1 ) and in 17 comparable normoalbuminuric (AER < 20 μg min −1 ) Type 2 diabetic patients. Plasma prothrombin fragment 1 + 2 was significantly higher in microalbuminuric than in normoalbuminuric patients (1.09 ± 0.06 vs 0.86 ± 0.04 nM, p = 0.003). Individual values of F1 + 2 were above the upper limit of the normal range in 8/17 microalbuminuric and in none of the normoalbuminuric Type 2 diabetic patients. Plasma thrombin‐antithrombin complex values were not significantly different in the two groups and were not correlated with AER. These results suggest that microalbuminuria is associated with a prethrombotic state and a relatively defective thrombin neutralization. Coagulation abnormalities might be part of the cardiovascular risk in microalbuminuric patients.
