How sulfapyridine causes acute hemolytic anemia is not known, and the reaction can only be classed as an idiosyncrasy.1 The beneficial effect of corticotropin (ACTH) on "idiopathic" acquired hemolytic anemia has been described by Dameshek,2 Gardner,3 Davidson,4 and their co-workers. Davidson and associates also noted no significant improvement when corticotropin was given to patients with congenital hemolytic anemia.

No account of the effect of corticotropin in acquired hemolytic anemia due to a drug has come to our attention.
