Objective:

To address the lack of standardized definitions for severity and relapse in vitiligo treatment and research, which complicates treatment strategies and patient management.

Key Findings:

• Vitiligo lacks standardized definitions of severity and relapse, complicating treatment strategies and patient management.
• Current clinical studies use inconsistent scoring and definitions, limiting comparability and meta-analysis, which affects treatment decisions.
• The new consensus defines relapse as loss of pigmentation in previously repigmented lesions after 3 months, providing a clearer framework for assessment.

Interpretation:

The lack of standardization has hindered treatment decisions and the assessment of therapy effectiveness in vitiligo, making it difficult to determine optimal patient management.

Limitations:

• Few recent JAK inhibitor trials have assessed relapse directly, often with small sample sizes, highlighting the need for further research.
• The consensus framework is a starting point and requires consistent application in practice and trials to be effective.

Conclusion:

The new framework represents a shift towards a multidimensional assessment of vitiligo, aiding in treatment decisions and tracking, but its successful implementation depends on consistent application.
