[Heroin-induced acute rhabdomyolysis].

A 24 year ald-man, was admitted in intensive care with coma and shock, 4 hours after intravenous injection of heroin. Awakening was obtained by naloxone. Diagnosis of acute rhabdomyolysis associated with heroin addiction was asserted by association of anury, hyperkalemia, and CPK increase. Recovery was obtained with, however, neurologic after-effects. Pathophysiology of acute rhabdomyolysis associated with heroin addict is obscure. Hypotheses for the cause of the muscle damage include the effects of toxicity (either directly or immunologically mediated) of the drug or an adulterant. However prolonged coma and immobilization in one position with either direct compression of the muscles or occlusions of the regional vascular supply can play a major role.
