[Fibrinolytic system in bronchial asthma after prednisone treatment].

Forty one patients with recently recognised bronchial asthma were studied. Activity of plasminogen activator inhibitor (PAI-1), platelet adhesion and aggregation, antigens of tissue and urokinase plasminogen activators (respectively, t-PA Ag and u-PA Ag), euglobulin lysis time (ELT), complexes of plasmin-antiplasmin (PAP) and fibrin degradation products (FDP) were tested before and after fourteen days administration of 20-30 mg/d prednisone. Statistical significant increase of PAI-1 activity, on the average about 75%, was found (8.35 +/- 9.38 U/ml before, and 14.6 +/- 13.3 U/ml after treatment; p < 0.02). In 31 asthmatic patients (75.6%), after prednisone treatment, increased of PAI-1 activity together with platelet adhesion and aggregation were observed. Among other studied fibrinolysis factors no statistical significant differences before and after treatment were found. These results suggest that in asthmatic patients after prednisone treatment raises PAI-1 activity, probability because of releasing of the increased amount of PAI-1 from activated platelet.

[Changes in platelet function, activated partial thromboplastin time and plasminogen activator inhibitor in patients with bronchial asthma after prednisone treatment].

Twenty patients with recently recognised bronchial asthma and 22 age and sex-matched healthy control subjects were studied. In both groups the activated partial thromboplastin time (APTT), prothrombin ratio (INR), fibrinogen, euglobulin lysis time (ELT), platelet number and platelet adhesion and aggregation, tissue plasminogen activator antigen (t-PA Ag) and activity of plasminogen activator inhibitor (PAI-1) were tested and compared. Statistically significant differences between asthmatic and control groups concerning adhesion, aggregation, APTT and ELT were found. In asthmatic group after 14 days of prednisone administration in a dose of 20 mg/d statistically significant (p < 0.05) shortening of APTT, and a significant increase of adhesion, aggregation and PAI-1 activity were found. These results suggest that in asthmatic patients after prednisone treatment platelet activity appeared in a form of intensification of adhesion and of aggregation degree, also the activity of PAI-1 probably of the platelet origin increased.

Fibrinolysis system in patients with bronchial asthma.

Every inflammatory process, including that in the course of bronchial asthma may disturb the balance in blood coagulation and fibrinolysis system. The aim of the present study was to evaluate fibrinolysis in patients with bronchial asthma. The study group consisted of 41 patients with bronchial asthma, hitherto untreated (25 women, 16 men, at mean age 37.37 +/- 12.4 years) and 22 healthy adults (control group). In these subjects, the following parameters were established: euglobulin lysis time (ELT), the concentration of tissue plasminogen activator antigen (t-PA Ag), the concentration of urokinase plasminogen activator antigen (u-PA Ag), the activity of plasminogen activator inhibitor type 1 (PAI-1), the concentration of plasmin-antiplasmin complex (PAP) and fibrinogen/fibrin degradation products (FDP). It was found that patients with bronchial asthma had statistically significantly higher mean values of FDP (9.25 +/- 6.7 micrograms/ml vs. 5.0 +/- 5.9 micrograms/ml; p < 0.001), ELT (123.5 +/- 42.7 min vs. 97.4 +/- 27.1 min; p < 0.001), t-PA Ag (8.36 +/- 3.66 ng/ml vs. 5.5 +/- 3.71 ng/ml; p < 0.01) and PAP complexes (250.3 +/- 95.8 ng/ml vs. 193.4 +/- 60.7 ng/ml; p < 0.02). Mean u-PA Ag concentration in patients with bronchial asthma was significantly lower than in control group (0.24 +/- 0.16 ng/ml vs. 0.53 +/- 0.18 ng/ml; p < 0.01). No statistically significant differences were observed as to PAI-1 activity between patients with bronchial asthma and healthy subjects. The results of the present study suggest that increased concentrations of t-PA Ag, PAP and FDP complexes are the evidence for greater activity of fibrinolysis system in subjects with bronchial asthma.
