Enfermedad de orina con olor a jarabe de arce: enfrentamiento de un caso / Maple syrup urine disease: case management

Maple syrup urine disease (MSUD) is an amino acidopathy secondary to a catabolic defect of branched amino acids (aa) valine, isoleucine and leucine (VIL). The accumulation of these elements and their keto acids in body fluids leads to encephalopathy and progressive neurological degeneration in untreated children (2-4-5-6)). The case of a newborn is analysed presenting with a classic form of this disease, its clinical evolution with metabolic and neurological involvement, diagnosis and intrahospital care till discharge.
