[The functional activity of plasminogen activators in the blood plasma and urine of patients with lupus nephritis].
A fibrin plate technique was employed to study functional activity of plasminogen activators in plasma and urine (FAAP, FAAU), activity of antiactivator in plasma (AAAP), urokinase urine activity (UUA) in 35 lupus nephritis (LN) patients. The latter comprise 3 groups by the disease severity: 22 patients with active LN attended by urinary syndrome (group 1), 7 patients with LN associated with nephrotic syndrome (group 2), 6 patients with rapidly progressing LN (group 3). Control groups included 5 SLE patients with unaffected kidneys and 25 healthy subjects. FAAP proved heterogeneous both in SLE and healthy subjects. SLE patients with progressive LN had diminishing FAAP which was accompanied by growing AAAP. The latter reached maximal values in groups 2 and 3. UUA declined with LN aggravation. The relation of low FAAP in LN patients to affection of vascular endothelium and binding of plasminogen activators with the inhibitors to form inactive complexes is considered.
