A mixed-method study exploring patient-experienced and caregiver-reported benefits and side effects of corticosteroid use in Duchenne muscular dystrophy
Fischer, R., Porter, K., Donovan, J. M., Scavina, M. T., Armstrong, N., Denger, B., Hasham, S., & Peay, H. (2023). A mixed-method study exploring patient-experienced and caregiver-reported benefits and side effects of corticosteroid use in Duchenne muscular dystrophy. Journal of Neuromuscular Diseases, (4). https://doi.org/10.3233/JND-221617
BACKGROUND: Corticosteroids are recommended to all people with Duchenne as standard of care; experience data is important to guide corticosteroid decision making and as a comparator for new treatment options.
OBJECTIVE: This study assesses patient and caregiver-reported benefits and side effects from corticosteroids to treat Duchenne muscular dystrophy, their importance, and satisfaction.
METHODS: Using one-on-one interviews (n = 28) and an online survey (n = 236), parents and adults with Duchenne reported corticosteroid benefits and side effects rated as both experienced and important.
RESULTS: Benefits to breathing, heart function, arm strength, slowing progression of weakness, and getting around were rated as particularly important, regardless of ambulatory status. Important side effects included increased fracture risk, unwanted weight gain, and diabetes/prediabetes. Parents rated behavior issues and adults rated delayed puberty as having high importance. Being ambulatory was independently associated with reporting more net benefit (p = 0.02). For side effects, parent scores were significantly higher than adult score (p = 0.02). Corticosteroid type was not significant. Participants were, overall, satisfied with corticosteroids (means ranging from 6.2 to 7.7 on a scale of 0-10), with no significant differences based on corticosteroid type.
CONCLUSIONS: Overall, most participants were satisfied with the use of corticosteroids. While a range of side effects were rated as important and relatively common, individuals using corticosteroids and their caregivers indicate that benefits outweigh the side effects. Qualitative data indicate that high acceptability is influenced by lack of treatment alternatives. Patient experience data on use of corticosteroids in Duchenne may be relevant to drug development, regulatory assessment of new treatments, and to families making decisions about corticosteroid use.
