Behaviour of fibrinolysis in the nephrotic syndrome.

When compared to 39 normal-weight normolipidemic control subjects, the dilute blood clot lysis time was found to be slightly (p less than 0.05) accelerated in the 49 investigated nephrotic patients, although their plasma fibrinogen, factor XIII as well as the inhibitors of fibrinolysis, are markedly increased. These findings indicate that the fibrinolytic system as a whole is not markedly depressed in the nephrotic syndrome. Although the fibrinolytic activity of euglobulins tested on agarose-fibrin plates was not significantly increased in nephrotic patients, one cannot definitely preclude an enhanced secretion of plasminogen activators in this pathological condition. A different quality of the inhibitors which may be less active in retarding dilute blood clot lysis time could also be considered.
