Advances in diagnosis and treatment of myocardial damage in childern DMD/BMD / 国际儿科学杂志

ABSTRACT

Duchenne/Becker muscular dystrophy(DMD/BMD)is a progressive, destructive neuromuscular disease.It is caused by mutations in the gene encoding dystrophy.The mutations come in various forms and the severity of the disease varies.The onset of the disease is insidious, and the initial manifestation is only abnormal serum enzymes.With the progression of the disease, the skeletal muscle and myocardial striated muscle cells are further destroyed, gait abnormalities and myocardial damage gradually appear, and eventually most children die of heart failure.At present, there is no effective radical cure.The existing treatment methods, including oral glucocorticoids and restoring functional dystrophin, are mostly limited to alleviate skeletal muscle symptoms, and are very limited to improve cardiac symptoms.This article reviews the progress in the diagnosis and treatment of myocardial damage in DMD/BMD, in order to provide reference for clinical research and gene therapy.
