[Acute renal failure due to rhabdomyolysis in McArdle's disease following binge drinking with seizures].
METHODS
A 36-year-old gardener was admitted for tonic-clonic seizures after binge drinking. The next days he developed massive rhabdomyolysis with acute renal failure. Past medical history was unremarkable except for a similar episode of acute renal failure 14 years ago. At that time he had consumed alcohol as well. Furthermore, the patient complained of exercise-related painful muscle cramping and swelling.


METHODS
The serum creatinine peaked at 8.5 mg/dl, blood urea at 126 mg/dl and the maximal level of serum creatinine kinase was 108 300 U/l. Because of the massive rhabdomyolysis and the patient inverted question marks past medical history a metabolic myopathy was suspected and a muscle biopsy was performed. Histochemical staining of muscle frozen sections for phosphorylase revealed no activity which is typical for myophosphorylase deficiency (McArdle inverted question marks disease). Additional biochemical analysis of the muscle biopsy specimen confirmed the diagnosis.


METHODS
By vigorous intravenous hydration and forced alkaline diuresis, the patient had a sufficient urinary output and lacked uremic signs. The serum creatinine and urea fell continuously and reached normal levels after 6 weeks. At that time serum creatinine kinase was still elevated (867 U/l), which is typical for McArdle inverted question marks disease. Avoiding alcohol, a new episode of rhabdomyolysis and acute renal failure did not occur.


CONCLUSIONS
Besides exercise alcohol is likely to be a further possible trigger of rhabdomyolysis and acute renal failure in McArdle inverted question marks disease. Postulated mechanisms by which alcohol induces muscle injury include direct muscle toxicity and inhibition of gluconeogenesis, as these patients are probably more dependent on the gluconeogenetic pathway for muscle cell metabolism.
