Minimal change nephrotic syndrome

Abstract

In minimal change nephrotic syndrome (MCNS), selective proteinuria is associated with structural alterations of the glomerular epithelial cells, such as effacement of the foot process. Although the pathogenesis of MCNS has not been completely clarified, clinical and experimental observations suggest that it results from T cell dysfunction in the pathogenesis. Recently, it has been proposed that the occurrence of MCNS has been associated with type 2 Th (Th2) lymphocyte-dependent conditions and some vascular permeability factors, which are induced by T cell disorder. In general, MCNS has the good long-term outcome with sustained remission and preserved renal function, because almost cases are responsible for the treatment. However, some patients show frequent relapses or resistance to this treatment and need large doses of immunosuppressive agents for a long time. Therefore, we should be care for the complications associated with prolonged these therapies.
