Management of a urea cycle disorder in the setting of socioeconomic and language barriers

Abstract

Argininosuccinic aciduria (ASA) is a disorder that results from a deficiency in the urea cycle enzyme argininosuccinate lyase. Variable manifestations of this hereditary disorder are associated with hyperammonemia and can include lethargy, somnolence, and respiratory alkalosis in neonates, and vomiting, headaches, and neurocognitive deficiencies later in life. Management of ASA includes rapid measures to address hyperammonemia and long-term steps to maintain metabolic stability. Management paradigms should also consider social determinants of health, which are non-medical factors that influence health outcomes. Here, we describe the case of a male pediatric patient with ASA whose treatment has included considerations for his family's refugee status, language barriers, cultural adjustments, limited income, and transportation challenges.
