title: Hyperuricemia in an infant with Taussig-Bing anomaly and interruption of the aortic arch.
abstract: Hyperuricemia is commonly recognized in adolescents and adults with cyanotic congenital heart disease. We report a case of a male infant with hyperuricemia, Taussig-Bing anomaly, and interruption of the aortic arch. The patient underwent correction of interrupted aortic arch and pulmonary arterial banding at the age of 7 days. Hyperuricemia appeared when he was 2 months old (max 17.7 mg/dl) and persisted until he underwent a Jatene operation at the age of 10 months. The hyperuricemia improved gradually after the disappearance of hypoxia and polycythemia. The laboratory findings suggest that hyperuricemia can result from uric acid overproduction due to secondary polycythemia, impairment of uric acid excretion by the kidney, or the acceleration of anaerobic metabolism. Allopurinol and benzbromarone together were partially effective treatments for hyperuricemia in this patient with cyanotic congenital heart disease.
