Abstract

Hepatic dysfunction was observed in 34 patients with nontraumatic rhabdomyolysis. The serum levels of lactic dehydrogenase were markedly elevated in all patients. The peak values occurred within 72 h of hospitalization. There was no significant difference among patients with (9,044 +/- 1,154 U/l) and without acute renal failure (ARF; 9,125 +/- 3,067 U/l). Similarly, marked elevation in both alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were observed within 72 h after admission to the hospital. They were significantly higher in patients with ARF (ALT: 4,718 +/- 785 vs. 2,496 +/- 927 U/l, p less than 0.01; AST: 3,635 +/- 820 vs. 1,352 +/- 624 U/l, p less than 0.01). Hyperbilirubinemia was noted in 13 of 22 (60%) patients with ARF and in 5 of the 12 (41%) of those without ARF. Serum levels of bilirubin ranged from 2.6 to 14.3 mg/dl. Prothrombin time was prolonged in 4 of 12 (33%) without ARF and in 14 of 22 (63%) of patients with ARF. This abnormality lasted from 1 to 13 days. The magnitude and duration of hyperbilirubinemia and abnormal prothrombin time were similar in patients with and without ARF. Hepatic dysfunction appears to occur in about 25% of patients with rhabdomyolysis. The pathogenesis of these abnormalities is not well defined and may be multifactorial. Hyperpyrexia, hypotension and proteases released from injured muscle may each or all be contributory. These hepatic derangements are reversible.
