Microalbuminuria in diabetic patients is associated with an increased cardiovascular risk which is not completely explained by an excess of conventional cardiovascular risk factors. A depression of physiologic inhibitors of blood coagulation could contribute to a thrombophilic state and to cardiovascular complications: data on protein C in diabetic patients are controversial, and no information exists about protein C activity in non-insulin-dependent diabetic patients or its relation to the microalbuminuric state. The aim of this study was to assess protein C activity in non-insulin-dependent diabetic patients with and without microalbuminuria. Protein C activity was determined (Protein C Reagent, Boehringer Mannheim, Germany) in 29 non-insulin-dependent diabetic patients with microalbuminuria (group A, > 20 micrograms/min), 33 non-insulin-dependent diabetic patients with normoalbuminuria (group B), and in 36 non-diabetic healthy blood donors as a control group (group C). The groups were matched for sex, and no difference in age, body mass index, blood pressure, glycated haemoglobin or known duration of diabetes was observed between groups A and B. Protein C activity was similar in the three groups (mean +/- SD): group A, 106.9% +/- 25.2%; group B, 109.3% +/- 27.6%; group C, 103.1% +/- 18.9%; F value 0.58, NS. Protein C activity did not correlate significantly with body mass index, glycated haemoglobin, known duration of diabetes, age or albumin excretion rate in any of the groups or in the diabetic patients as a whole. No significant difference in protein C activity was observed in patients taking other therapy (diet, oral agents, insulin).(ABSTRACT TRUNCATED AT 250 WORDS)

Microalbuminuria and haemostasis derangements have been considered as independent risk factors for cardiovascular death in type 2 (non-insulin-dependent) diabetic patients. Few studies have assessed coagulation inhibitors in type 2 diabetic patients with normoalbuminuria and microalbuminuria. Therefore, 32 type 2 diabetic patients with normoalbuminuria (albumin excretion rate, AER < 20 mg/min, mean 7 +/- 1) and 28 type 2 diabetic patients with microalbuminuria (AER 20-200 mg/min, mean 84 +/- 11) were studied. The patients were matched for age, sex, disease duration and treatment, body mass index (BMI), blood pressure and glycohaemoglobin. Protein C and S activity, antithrombin III, thrombomodulin and prothrombin fragments 1 + 2 (F 1 + 2) were assessed together with fibrinogen, triglycerides, total and high density lipoprotein (HDL)-cholesterol concentrations. Fibrinogen, total and low density lipoprotein (LDL) concentrations were similar in the two groups, while a significant difference was observed for triglycerides (normoalbuminuric group: 128 +/- 10 mg/dl, microalbuminuric group: 184.1 +/- 17 mg/dl; P < 0.007) and HDL-cholesterol (normoalbuminuric group: 45 +/- 2 mg/dl, microalbuminuric group: 39 +/- 2 mg/dl; P < 0.05). The coagulation parameters were as follows: normoalbuminuric group: protein C activity 109% +/- 5%, protein S 95.4% +/- 5%, thrombomodulin 49.3 +/- 3 ng/ml, antithrombin III 93.3% +/- 3%, F 1 + 2 1.05 +/- 0.04 nmol/l; microalbuminuric group: protein C activity 107% +/- 4%, protein S 98.4% +/- 4%, thrombomodulin 64.4 +/- 4 ng/ml, antithrombin III 93.3% +/- 3%, F 1 + 2 1.03 +/- 0.05 nmol/l. The difference was significant for thrombomodulin (P < 0.007). A significant direct correlation was observed in the microalbuminuric group between AER and thrombomodulin (r = 0.38, P < 0.05). In conclusion, our data do not support the hypothesis that a reduction in the activity of anticoagulant physiological inhibitors (protein C, protein S, antithrombin III) could contribute to explain the higher cardiovascular risk in type 2 diabetic patients with microalbuminuria. The elevation of plasma thrombomodulin concentration in type 2 diabetic patients could be the consequence of widespread vascular damage in diabetic patients with incipient nephropathy.
