Perturbations in Amino Acid Metabolism in Children with Kaschin-Beck Disease: A Study of Urinary Target Metabolomics

摘要

Kaschin-Beck disease (KBD) is an endemic and chronic osteoarthropathy characterized by pathological aspects including chondrocyte degeneration, necrosis, progressive loss of articular cartilage, and secondary degenerative osteoarthrosis of epiphyseal cartilage, epiphyseal plate cartilage, and articular cartilage, during puberty[1]. The main clinical symptoms are limb joint pain, thickening, deformation, limited movement, muscle atrophy, and in case of more severely affected patients, short fingers (toes), short limbs, and even short stature[1].
