Abstract

Barth syndrome (BTHS) is a rare, X-linked cardiomyopathy that is characterized by abnormalities in glucose and lipid metabolism, with less known regarding amino acid metabolism. This pilot study characterized whole-body arginine kinetics and found lower arginine rate of appearance into plasma (0.69 ± 0.09 vs. 0.88 ± 0.06 μmol/kgFFM/min, p < 0.01) and arginine non-oxidative disposal rate (0.64 ± 0.11 vs. 0.80 ± 0.03 μmol/kgFFM/min, p < 0.02) in adolescents and young adults with BTHS compared to Controls. This study provides a foundation for more in-depth studies on how arginine and potentially other amino acid abnormalities contribute to the pathology and clinical manifestations of BTHS.
