Minimal change nephrotic syndrome (MCNS) is the most common cause of nephrotic syndrome (NS) in children. However, this disease also occurs in adults as an idiopathic abnormality, in association with lymphoid and other neoplasms and with administration of therapeutic agents. The pathogenesis of MCNS is not completely understood, but there is now consensus that a glomerular permeability factor in some cases is responsible for the clinical and pathological features of the disease [1–4]. Data to support this include isolation of a permeability factor produced by clonal expansion of T-cells that alters albumin permeability of rat glomerular epithelial cell monolayers [3] and induces proteinuria when injected into rats [4]. Other investigators suggest MCNS is a systemic disorder of T-cell function and cell-mediated immunity [1,2]. However, the role of T-cells and their products in the development of MCNS is not defined.
