To evaluate the possibility that platelet dysfunctions contribute to the cardiovascular risk of microalbuminuric insulin-dependent diabetic (IDD) patients, we have measured beta-thromboglobulin (BTG) and platelet factor 4 (PF4) in 74 IDD patients with different degrees of albuminuria (8 macro-, 36 micro- and 30 normoalbuminuric) and in 30 non-diabetic control subjects. BTG values (20.4 +/- 1.5 SEM in normo-, 22.2 +/- 1.2 in micro-, 101.1 +/- 2.9 in macroalbuminuric patients and 21.8 +/- 1.1 IU/ml in control subjects) were significantly higher (P < 0.001) in the macroalbuminuric patients, but similar among the other groups. These results suggest that platelet hyperactivation is not present in the microalbuminuric stage of diabetic nephropathy, only in overt nephropathy
Plasma beta-thromboglobulin and platelet factor 4 are not increased in insulin-dependent diabetic patients with microalbuminuria

Abstract
To evaluate the possibility that platelet dysfunctions contribute to the cardiovascular risk of microalbuminuric insulin-dependent diabetic (IDD) patients, we have measured beta-thromboglobulin (BTG) and platelet factor 4 (PF4) in 74 IDD patients with different degrees of albuminuria (8 macro-, 36 micro- and 30 normoalbuminuric) and in 30 non-diabetic control subjects. BTG values (20.4 +/- 1.5 SEM in normo-, 22.2 +/- 1.2 in micro-, 101.1 +/- 2.9 in macroalbuminuric patients and 21.8 +/- 1.1 IU/ml in control subjects) were significantly higher (P < 0.001) in the macroalbuminuric patients, but similar among the other groups. These results suggest that platelet hyperactivation is not present in the microalbuminuric stage of diabetic nephropathy, only in overt nephropathy
