[Acute intermittent porphyria].
Acute intermittent porphyria is an inherited disease caused by genetic deficiency of enzyme prophobilinogen deaminase, which stopped heme synthesis. It is characterized by overproduction, accumulation and excretion of heme precursors. The authors present a young woman with clinical signs and symptoms of disease, treated successfully with heme-arginate, a newly synthetized drug in clinical use since 1985.
