Bilateral adrenal hemorrhage and adrenal insufficiency in a patient with lymphomatous adrenal infiltration following administration of a fusion toxin (DAB486 interleukin-2).
DAB486IL-2 is a novel fusion toxin in which the ADP-ribosyltransferase and membrane-translocating domains of diphtheria toxin have been combined with the interleukin-2 (IL-2) gene, creating a recombinant protein capable of selectively intoxicating cells bearing the high-affinity IL-2 receptor. Clinical activity has been documented in Hodgkin disease and the non-Hodgkin lymphomas; toxicities have been minimal and include mild hepatic transaminitis, proteinuria, and hypersensitivity reactions. In this report, a patient with tumor-stage cutaneous T-cell lymphoma developed clinical adrenal failure with bilateral adrenal hemorrhage and necrosis 7 weeks after completing a 5-day course of treatment with DAB486IL-2. The relationship of fusion toxin therapy to the development of this unusual toxicity is discussed.
