|---|
The identification and characterization of circulating factors that alter glomerular permeability in idiopathic nephrotic syndrome (INS) remain the subject of intensive research in nephrology. The existence of such factors was initially evoked by Shalhoub in 1974 [1] and, although they are thought to be of T-cell origin, their precise nature remains elusive. INS recurs immediately after kidney transplantation in 30% of patients with corticosteroid- or cyclosporin A-resistant INS [2]. The rapidity of this recurrence and the beneficial effects of plasmapheresis [2] and/or immunoadsorptions [3], together with several cases of materno-fetal transmission of glomerular abnormalities [4], lend credence to the involvement of plasmatic factors. In addition, the beneficial effects of corticosteroids and/or immunosuppressive therapies on the initial disease and the T-cell abnormalities recently reported in steroid-sensitive INS [5] indirectly support a T-cell origin.
