Abstract
The authors present a case of acute intermittent porphyria (AIP) in an almost fatal relapse with quadriplegia, bulbar paralysis and coma. Intravenous hematin produced an immediate arousal from coma and allowed a gradual resumption of bulbar and autonomic functions. Persistent tachycardia and hypertension necessitated huge doses of intravenous propranolol. Both hematin and propranolol administrations were followed by a remarkable decrease in urinary amino-levulinic acid and porphobilinogen excretion. Nevertheless, after the acute stage, the patient was left with a severe generalized muscle wasting. After 7 months of intensive physical therapy, complete recovery of all neuromuscular functions was achieved. The modern aspects of the management of AIP are presented; the efficacy and the limits of hematin and propranolol therapy are discussed.
