Diagnostic/classification criteria in pediatric Behçet's disease

Area of Science:

• Rheumatology
• Pediatric Rheumatology
• Vasculitis Research

Background:

• Behçet's disease (BD) is a systemic vasculitis with variable presentations.
• Pediatric BD (PEDBD) exhibits distinct characteristics compared to adult-onset disease.
• Existing diagnostic criteria for BD are largely based on adult studies and lack pediatric validation.

Purpose of the Study:

• To review and analyze diagnostic/classification criteria for Behçet's disease.
• To evaluate the performance and applicability of current criteria in pediatric BD.
• To identify needs for improved diagnostic standards in childhood BD.

Main Methods:

• Systematic review of published diagnostic/classification criteria for Behçet's disease.
• Analysis of studies assessing the performance of these criteria specifically in pediatric populations.
• Discussion of factors influencing the universal acceptance and utility of criteria.

Main Results:

• The revised International Criteria for Behçet's Disease (ICBD) demonstrate the highest sensitivity in pediatric studies.
• The International Study Group (ISG) criteria exhibit the highest specificity among evaluated sets.
• Limited pediatric research exists, highlighting a gap in evidence for criterion validation.

Conclusions:

• Current diagnostic criteria for Behçet's disease require further validation in pediatric populations.
• Revised ICBD and ISG criteria show promise but need refinement for optimal use in children.
• Larger, multinational pediatric cohorts are essential for robust comparison and improvement of diagnostic criteria.
