Laboratory indexes in patients with glomerulonephritis in hemorrhagic vasculitis
One of the main signs of hemorrhagic vasculitis is glomerulonephritis. Fibronectinuria represents severity of glomerular changes and b2-microglobulinuria shows development of tubulointerstitial damages even in patients without glomerulonephritis in hemorrhagic vasculitis. Levels of fibronectin in urine >0,64 mcg/mol, IgМ >1,7 g/l and fibrinogenum >6,3 g/l in blood reflect severity glomerulonephritis in hemorrhagic vasculitis. b2-microglobulinuria in patients with glomerulonephritis in hemorrhagic vasculitis does not depend on the presence of nephritic syndrome and renal failure. The average arterial blood pressure correlates directly with level of common proteinuria.
