Similarity Between Eruptions Induced by Sulfhydryl Drugs and Acute Cutaneous Graft-versus-host Disease After Bone Marrow Transplantation

Abstract

Cutaneous GVHD is histologically similar to eruptions induced by drugs containing a sulfhydryl group. The levels of interleukin-2 and interleukin-2 receptor were determined in a group of patients undergoing bone marrow transplantation (BMT) without graft-versus-host disease or any other complications and in a group with cutaneous graft-versus-host disease (GVHD) alone. In patients who only developed cutaneous GVHD, both interleukin-2 and inter-leukin-2 receptor levels were elevated when the disease was evident. As the elevation of these parameters became more marked, the grade of cutaneous graft versus-host disease also increased. In some patients, only one of the two parameters was elevated and the grade of graft-versus-host disease was low or no skin manifestations were seen. These findings suggest that interleukin-2 and interleukin-2 receptor act together in the development of cutaneous GVHD. This study also showed that the mechanism of cutaneous GVHD resembles that involved in the induction of eruptions by sulfhydryl-containing drugs.
