The thrombocyte aggregability (TA) and central, peripheral, renal hemodynamics were studied in relation to therapy in patients with acute, chronic, lupus nephritis (AGN, ChGN, LN). The investigation showed that it was noted the increase TA in the cases of AGN, ChGN and LN with nephricоtic form and decrease after pathogenic therapy. ТАpatients with latent variants of GN was in normal limited as before, so as after symptomatic therapy. In all forms of GN it was noted hypokinetic type of hemodynamics, considerable aggravation of renal hemodynamics: decreaseof effective renal plasma flow (ERPF) and blood flow (ERBF), increase of renal vascular resistance (RVR).
