Implication

Randomized trial evaluates interferon-related gene expression as a biomarker for disease activity in juvenile dermatomyositis, suggesting its clinical utility.

Key Points

This research aims to explore how interferon-related gene expression correlates with disease activity and treatment response in juvenile dermatomyositis.
Assessed 74 patients with juvenile dermatomyositis using standard clinical measures.
Analyzed associations between interferon-related gene expression and clinical features using correlation analyses and mixed-effects models.
Explored longitudinal trajectories of disease activity and treated patients using baricitinib.
Type-I interferon-related gene expression was significantly higher during active disease and correlated positively with muscle and skin activity.
Distinct correlations were identified, such as CXCL9 with lung disease and IL-18 with gastrointestinal issues.
The expression levels decreased in patients achieving inactive disease after treatment, indicating potential as a biomarker.
