    Abstract:
    A venous occlusion test was used to evaluate the reserves of the kidneys and that of vascular endothelium fibrinolytic activity (VEFA) in patients with lupus nephritis (LN). Prior to and following venous occlusion functional activity of plasminogen activators in plasma and urine (PAPU), plasma activity of antiactivator (PAAA), urokinase urine activity (UUA) were measured by fibrin plate lysis test in 24 patients with active LN, 6 SLE patients with intact kidneys, 10 healthy subjects. Venous occlusion test revealed normal reserve of plasma activator activity in mild LN and depletion of this reserve in LN patients with nephrotic syndrome and rapidly progressive LN. In the latter patients PAPU and PAAA were suppressed. PAPU reserve existed in all the patients, but those with rapidly progressive LN. UUA in LN was close to normal and did not change significantly after venous occlusion. The data obtained suggest that patients with severe LN had reduced reserves of VEFA, while in those with progressive LN there were also diminished reserves of renal fibrinolytic activity reflecting the severity of endothelial lesion.
