Cyclosporin A treatment for membranoproliferative glomerulonephritis type II.

A nephrotic patient with membranoproliferative glomerulonephritis type II (MPGN II) was treated with cyclosporin A (CSA) and alternate-day low-dose prednisolone. This patient developed the nephrotic syndrome twice. The second episode of the nephrotic syndrome was steroid resistant, and therefore this patient was treated with a CSA regimen. During treatments with alternate-day low-dose prednisolone and CSA, this patient recovered from the nephrotic syndrome. We conclude that CSA therapy may be effective for patients with the steroid-resistant nephrotic syndrome caused by MPGN II.
