[Estimation of podocyte dysfunction by nephrinuria severity in proteinuric forms of chronic glomerulonephritis].

Aim: To evaluate severity of nephrinuria (NU) as a marker of podocyte dysfunction (PD) in patients with proteinuric forms of chronic glomerulonephritis (CGN) and to specify efficacy of this test for assessment of activity and prognosis of CGN.

Material And Methods: We examined 74 CGN patients: 18 with inactive nephritis (group 1), 18--with subnephrotic proteinuria (group 2), 38--with nephrotic syndrome--NS (group 3). The control group consisted of 10 healthy subjects.
