В большинстве случаев IgM-нефропатия характеризуется гормонозависимостью или гормонорезистентностью, или частыми рецидивами, что диктует необходимость присоединения к терапии цитостатика. В детском возрасте характеризуется доброкачественным течением без признаков прогрессирования.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>BACKGROUND</title><p>BACKGROUND.

In most cases, IgM nephropathy is characterized by steroid dependence or resistance, or frequent relapses, which dictates the need to join cytostatic agent.
