Thrombotic microangiopathy in a patient with chronic myelocytic leukaemia treated with α-interferon

Abstract
Adverse effects of interferon (IFN) therapy on the kidney are proteinuria, rarely nephrotic syndrome, and renal failure [1–7]. Two forms of renal failure have been described: an acute form, i.e. acute interstitial nephritis or an acute tubular necrosis, occasionally associated with minimal-change nephropathy [2] or chronic progressive renal failure, usually thrombotic microangiopathy [3–7], potentially progressing to end-stage renal failure (ESRF).
