Case Reports
Subacute myopathy in a mature patient due to multiple acyl-coenzyme A dehydrogenase deficiency.
Multiple acyl-coenzyme A dehydrogenase deficiency (MADD), also called glutaric aciduria type II, is an inherited metabolic disorder resulting from a deficiency in electron transfer flavoprotein (ETF) or of its ubiquinone oxidoreductase (ETF-QO). It usually occurs in the neonatal period or in early infancy and, very rarely, in adolescents and young adult patients. ⋯ This study demonstrates that metabolic myopathies usually found in infancy may be also diagnosed in older patients. MADD may be easily treated by riboflavin and coenzyme Q10 and therefore should be included in the differential diagnosis of adult-onset painful myopathy.
