Drug Eruptions From Mesna

Abstract

Two distinct eruptions to mesna have been induced in these patients during cyclophosphamide/corticosteroid therapy; these eruptions are not thought to share a common pathogenic mechanism. The results of skin and challenge tests do not support the hypothesis that a type 1 or a type 4 immune reaction may be responsible for these eruptions. The unusually high incidence (about 50%) of these reactions and their clinical presentation make it important to distinguish them from an exacerbation of the preexistent autoimmune disorder.
