Recurrent reversible rhabdomyolysis associated with hyperthermia and status epilepticus
Abstract:
A 6-year-old boy developed rhabdomyolysis following hyperthermia and status epilepticus with a diagnosis of severe myoclonic epilepsy of infancy. At 2 and 3 years of age, he had similar episodes. Each time he recovered completely in 3-4 weeks with conservative management, in spite of renal insufficiency and marked liver dysfunction. Several cases of recurrent myoglobinuria after intense exercise of generalized tonic-clonic convulsions were reported to have genetic errors of carbohydrate or lipid metabolism of muscle. In our patient, however, the activity of these enzymes was found to be normal. This indicates that status epilepticus may cause recurrent rhabdomyolysis in subjects with normal glycolytic and lipolytic enzyme activity.
Insights
Status epilepticus can cause recurrent rhabdomyolysis (muscle breakdown) even in individuals with normal muscle enzyme activity. This case highlights a potential link between seizures and muscle injury, independent of metabolic disorders.
Area of Science:
- Neurology
- Pediatrics
- Metabolic Disorders
Background:
- Rhabdomyolysis, characterized by muscle breakdown and myoglobin release, can occur after intense physical activity or seizures.
- Recurrent rhabdomyolysis has been linked to genetic metabolic disorders affecting muscle carbohydrate or lipid metabolism.
- Severe myoclonic epilepsy of infancy is a rare and severe form of epilepsy presenting in infancy.
