[Acute renal failure in alcoholic myopathy (author's transl)].

Two chronic alcoholics developed acute renal failure from alcoholic myopathy (acute alcohol-induced rhabdomyolysis). Severe muscle pain developed and was associated with transitory oligo-anuric renal failure, requiring dialysis in one patient. In addition to the typical history and clinical symptoms, excessive elevation of muscle enzymes, especially creatine-kinase, and the appearance of myoglobin in serum are characteristic. Brown discoloration of the urine and a falsely positive test for "blood" due to the presence of myoglobin in urine in the absence of red blood cells are also typical. Definite changes can be demonstrated histologically and electromyographically during the acute stage. It is likely that this condition is more frequent than the sparsity of published reports indicates.
