Highlights from the breakout session: vasculitis in paediatric rheumatology

Area of Science:

• Rheumatology and Immunology
• Pediatric Medicine
• Genetics

Background:

• The 21st International Vasculitis Workshop convened to discuss recent advancements in pediatric vasculitis.
• Focus areas included common childhood conditions like IgA Vasculitis (IgAV) and Kawasaki Disease (KD).
• A holistic, multidisciplinary approach to managing these complex diseases was emphasized.

Purpose of the Study:

• To review and synthesize current research findings and clinical practices in pediatric vasculitis.
• To evaluate the performance of existing diagnostic criteria, such as the Ankara 2008 criteria for IgAV in adults.
• To explore novel therapeutic targets and diagnostic biomarkers for improved patient management.

Main Methods:

• Review of studies on genetic associations (e.g., Human Leukocyte Antigen polymorphisms in IgAV).
• Presentation of research on biomarkers (e.g., S100A8/A9, HMGB1, RAGE) for vasculitis.
• Discussion of novel therapeutic strategies, including anti-apolipoprotein A-2 antibodies for Kawasaki Disease and recommendations for monogenic vasculitides like ADA2 deficiency.

Main Results:

• Ankara 2008 criteria for IgAV showed high sensitivity in adults but require refinement for specificity.
• Novel anti-apolipoprotein A-2 antibodies demonstrated potential in mitigating coronary arteritis in Kawasaki Disease.
• New consensus-driven recommendations were established for managing monogenic vasculitides, including ADA2 deficiency.

Conclusions:

• Continued research is crucial for advancing the diagnosis and management of pediatric vasculitis.
• Tailored therapeutic strategies are essential for improving outcomes in children with vasculitis.
• The workshop highlighted progress towards better understanding and treatment of these rare diseases.
