Cyclosporin A in adult patients with Henoch-Schönlein purpura nephritis and nephrotic syndrome; 5 case reports.

Henoch-Schönlein purpura (HSP) is usually followed by mild renal involvement, but heavy proteinuria may also occur. Limited experience with cyclosporin A in children shows reduction of proteinuria. In this report, the use of cyclosporin A in 5 adult HSP patients with nephrotic-range proteinuria is described. Cyclosporin A in combination with prednisolone was given in 3 patients with HSP nephritis and nephrotic syndrome after a course of other immunosuppressive drugs and in 2 patients as initial treatment. All patients showed complete or partial remission of nephrotic syndrome with cyclosporin A and preserved stable renal function over a follow-up period of 5 years. We conclude that the combination of cyclosporin A with corticosteroids is effective in inducing remission of nephrotic syndrome in adult patients with HSP nephritis.
