Objective:

To document the clinical features and disease course of three African children with anti-MDA5-associated juvenile dermatomyositis (JDM) and interstitial lung disease (ILD), focusing on specific clinical outcomes and treatment responses, and to review the literature on rapidly progressive ILD related to MDA5.

Approach:

Key Findings:

• Anti-MDA5 autoantibodies are associated with a unique clinical profile in JDM, including higher risks for ILD and RP-ILD, as evidenced in the presented cases.
• The prevalence of anti-MDA5 in JDM varies significantly by geographic and ethnic backgrounds, with the cases highlighting this variability.
• The first documented cases of anti-MDA5-associated JDM in African children were presented, showcasing distinct clinical features and treatment challenges.

Interpretation:

The cases illustrate the complexity of managing anti-MDA5-associated JDM and ILD, emphasizing the need for tailored therapeutic strategies in diverse populations, particularly in underrepresented groups.

Limitations:

• Limited number of cases presented restricts generalizability and may introduce selection bias.
• Lack of comprehensive data on anti-MDA5-associated JDM in African populations limits the understanding of the disease in this context.

Conclusion:

The study underscores the importance of recognizing and treating anti-MDA5-associated JDM and ILD in children, particularly in underrepresented populations, and suggests the need for further research to optimize management strategies in light of existing literature.
