Protein C Activity

SummaryA simple and fast method for the quantitative determination of protein C activity in plasma is here described. The first step consists in the conversion of protein C in the test sample into activated protein C by means of an activator isolated from Southern Copperhead venom. Subsequently, the degradation of factor Va, in presence of protein C-deficient plasma, is measured by the prolongation of the prothrombin time which is proportional to the amount of protein C in the sample. The dose-response curve showed a linear relationship from 6 to 150% protein C activity and the inter- and intra-assay reproducibility was 3.5% and 5.6% respectively. In normal subjects, a mean of protein C level of 98 ± 15% of normal pooled plasma was found. Comparison with the anticoagulant assay in samples of patients with oral anticoagulant, liver cirrhosis, disseminated intravascular coagulation and severe preeclampsia revealed an excellent correlation (r = 0.94, p <0.001). Also, a similar correlation (r = 0.93, p <0.001) existed between amidolytic assay and the method here proposed for all the samples studied without including the oral anticoagulant group. These results allowed us to infer that this method evaluates the ability of protein C to interact with protein S, phospholipids, calcium ions and factor Va.

Protein C Activity

SummaryIn patients with severe nephrotic syndrome determinations of plasma protein C : Ag levels (8 patients: 5 adults, 3 children) and protein C activity (3 out of 8 patients) revealed significantly elevated plasma protein C concentrations. Furthermore we observed a significant inverse correlation of protein C : Ag to AT III : Ag levels. No protein C : Ag could be detected in the urine of two patients studied. We conclude from our data, that changes of plasma protein C do not contribute to the high thrombotic tendency in nephrotic syndrome.

The haemostatic system was investigated in 26 women taking cyclically administered triphasic combined oral contraceptives for the first time during their first six cycles. Fourteen women received Logynon (mean dose 32.4μg ethinyloestradiol, 92pg progestagen) and 12 received SHD 415G (Schering) which contains a mean dosage of 32.4μg ethinyloestradiol and 78pg gestodene, a recently developed progesterone. The Logynon group showed a significant increase (p<0.005) in fibrinogen (pre-mean 284.4 g/1; after 1 cycle 347.3 g/1, after 6 cycles 318.6 g/1) , factor VII (65.8 u/1 to 73.9 u/1 to 83.2 u/1), factor XII (1.74 u/1 to 2.41 u/1, to 2.25 u/1), plasminogen (100.9 u/1 to 135.1 u/1 to 126.3 u/1); decrease in ATIII (115.9 u/1 to 103.1 u/1 to 93.4 u/1) but no significant change in factor X (98.4 u/1 to 108.9 u/1 to 102.4) or protein C (0.85 u/1 to 0.88 u/1 to 0.94 u/1) activity. The SHD 415G group showed similar changes with an increase in fibrinogen (247.9 g/1 to 330.8 g/1 to 373 .1 g/1), factor VII (63.1 u/1 to 73.1 u/1 to 90.3 u/1, factor X (98.3 u/1 to 112.0 u/1 to 124.4 u/1), factor XII (1.46 u/1, to 1.93 u/1, to 2.03 u/1), plasminogen (110.8 u/1 to 125.4 u/1 to 136.7 u/1); decrease in ATIII (113.1 u/1 to 96.3 u/1 to 89.7 u/1), but no change in protein C (0.84 u/1 to - 0.78 u/1 to 0.85 u/1) activity. These changes were apparent after the first cycle of therapy and the differences were maintained over the six cycle period. There was no increase in protein C activity despite changes in the other vitamin K dependent proteins factors VII and X. Both low oestrogen dose triphasic pills caused similar prothrombotic changes which were not modified by the new progesterone, gestodene.
