Prednisone and deflazacort in Duchenne muscular dystrophy: a patient perspective and plain language summary publication of the Cincinnati study

What is this summary about? This is a summary of an article about the Cincinnati study, which was published in the Journal of Comparative Effectiveness Research in January 2020. The Cincinnati study reviewed data from 435 males with Duchenne muscular dystrophy, also known as DMD, who were treated at the Cincinnati Children's Hospital Medical Center. DMD is a rare disease that worsens over time. People with DMD experience inflammation in their muscles and muscle loss over time. They also experience bone problems such as an abnormally bent spine, also known as scoliosis, as well as heart and lung problems. What happened in the Cincinnati study? Prednisone and deflazacort are steroids that help to reduce muscle inflammation and are used as treatments for DMD. The study researchers wanted to further understand the differences between using prednisone and deflazacort in males with DMD by reviewing data from past medical records of patients seen in clinics rather than in clinical studies. This is known as gathering real-world evidence. In the Cincinnati study, the researchers compared males with DMD who started taking prednisone as their first steroid treatment with males who started taking deflazacort as their first steroid treatment. What were the results? Overall, the researchers found that the participants who took deflazacort were able to walk until a later age before they needed to use a wheelchair, compared with those who took prednisone. They also had a lower risk of scoliosis and developed it at a later age. What do the results of the study mean? These results helped the researchers to learn more about the differences between how well prednisone and deflazacort work in males with DMD based on their medical records.
