Hematin treatment of acute porphyria. Early remission of an almost fatal relapse.

Intravenous infusions of hematin in a young woman with acute porphyria in profound relapse was followed within 48 hours by remission of symptoms and rapid recovery. From a state of severe central and peripheral nervous-system involvement, the patient recovered so completely that she was able to leave the hospital in less than a month, with only a residual weakness of her arms. Serial studies of serum and urinary levles of porphyrin precursors and serum level of hematin provided highly important information about the effect of hematin on acute porphyria.
