Key result
In patients with juvenile dermatomyositis, a disease duration > 4 years significantly increased the risk of disease damage based on the Myositis Damage Index score (AOR 8.3; 95% CI 1.7-41.7).
Population
53 patients with juvenile dermatomyositis (JDM)
Design

May warrant intensified damage surveillance beyond 4 years in juvenile dermatomyositis; leaves open need for prospective validation and modifiable-factor trials.
Cross-Sectional (n=53)
Odds Ratio: 8.3 (95% CI 1.7–41.7)
In patients with juvenile dermatomyositis, longer disease duration and higher age at onset are significant predictors of long-term disease damage.
Mathiesen et al. (2011) conducted a cross-sectional in Juvenile dermatomyositis (n=53). Disease duration > 4 years vs. Disease duration ≤ 4 years was evaluated on Risk of damage based on Myositis Damage Index (MDI) score (AOR 8.3, 95% CI 1.7-41.7). In patients with juvenile dermatomyositis, a disease duration > 4 years significantly increased the risk of disease damage based on the Myositis Damage Index score (AOR 8.3; 95% CI 1.7-41.7).
