title: Rhabdomyolysis and acute renal failure in chronic alcoholics with myopathy, unrelated to acute alcohol ingestion.
abstract: Rhabdomyolysis leading to acute renal failure necessitating hemodialysis is described in three chronic alcoholics. In each case an acute medical or surgical event, but not alcoholic intoxication, was implicated. Renal biopsies demonstrated acute tubular necrosis with intraluminal deposits consisting of Tamm-Horsfall protein and myoglobin. After recovery all three patients were demonstrated to have proximal muscle weakness with similar electromyographic abnormalities but nerve-conduction was impaired in only two. Muscle biopsies showed mixed, but predominantly type II fiber atrophy and reduced muscle phosphorylase levels. In the one patient tested the lactate response to forearm muscle ischemia was abnormal. It is postulated that chronic alcoholics may be predisposed to rhabdomyolysis and acute renal failure following acute medical and surgical stress as well as acute alcohol abuse. The muscle damage in these patients may be due to impaired intra cellular glycogen metabolism.
