Abstract

Objective To determine the effects of glucocorticoids on major motor function of Duchenne muscular dystrophy patients from a database registered in China.Methods In this cross-sectional study, we analyzed the clinical data,use of glucocorticoids and major motor function of genetically confirmed DMD patients from our national DMD registry and multidisciplinary clinic databases.Results 1182 dystrophinopathy patients were registered, 996 of which are confirmed DMD patients. 35.2% of DMD registrants in the database were treated with corticosteroids at their first clinical outpatients, compared to the current situation where 57.1% are using corticosteroids. The age of loss of ambulation in non-corticosteroids treated group is (10.50±0.37) years old, and (11.88±0.33) years old in corticosteroid treated group. Between age 7.0-11.9, 94.2% of corticosteroid treated group are capable of walking. Their 6-minute-walking-distance performances are (329.00±11.48) meters, and the Gowers’ time performances are (9.84±0.71) seconds. In contrast, 76.5% of non-corticosteroids treated group have the capability to walk and achieve (126.3±1.09) meters in the 6-minute-walking-distance test. The mean of their Gower’s performance is (10.02±1.41) seconds. 46.6% of corticosteroid treated group are capable of walking after 12 years old, compared to 12.2% in non-corticosteroids treated group.Conclusions Our data confirms the benefits of glucocorticoids treatment for motor function of DMD patients. Standardized registration and multidisciplinary diagnosis are of great significance for Duchenne muscular dystrophy.
