Abstract
- Mitochondrial myopathies are diseases caused by defects in metabolic pathway of mitochondria. Mitochondrial myopathy is known as one of the causes of recurrent myoglobinuria, while clinically, rarely causes acute renal failure requiring medical treatments. We report a case of rhabdomyolysis and acute renal failure associated with mitochondrial myopathy. A 58-year-old male was presented with dyspnea and hypotensive shock. The patient had a history of recurrent dark colored urine and cramping leg pain after prolonged fasting. Laboratory findings showed hyperkalemia, azotemia, metabolic acidosis, and elevated AST, ALT, and creatinine kinase. He had no history of trauma or medication. Muscle biopsy showed "ragged red fibers" in modified Gomori staining. On electron microscope, increased number of mitochondria and abnormal mitochondria were seen. He received hemodialysis and his renal function recovered after 1 month.
