Summary
Vitiligo patients have a higher risk of thyroid disease. Specific clinical features can guide targeted thyroid screening, improving early detection and personalized care.
Area of Science:
- Immunodermatology
- Endocrinology
- Autoimmunity
Background:
- Vitiligo is a chronic immune-mediated depigmenting disorder.
- Autoimmune thyroid disease is the most common comorbidity in vitiligo patients.
- Thyroid abnormalities are more frequent in vitiligo patients than the general population.
Purpose of the Study:
- To review the epidemiology, clinical predictors, and pathogenic mechanisms linking vitiligo and thyroid disease.
- To focus on practical screening considerations for thyroid dysfunction in vitiligo patients.
- To propose a phenotype-guided approach for thyroid screening.
Main Methods:
- Narrative review of existing literature.
- Examination of clinical and phenotypic characteristics associated with thyroid disease risk.
- Analysis of screening strategies and diagnostic yield.
Main Results:
- Nonsegmental vitiligo, acral involvement, female sex, extensive disease, longer duration, family history, and other autoimmune disorders increase thyroid disease risk.
- Thyroid autoantibodies and subclinical hypothyroidism are common findings.
- Thyroid disease can precede or follow vitiligo onset.
Conclusions:
- A targeted, phenotype-guided screening approach improves diagnostic yield and reduces unnecessary testing.
- Thyroid-stimulating hormone (TSH) is a practical initial screening test.
- Integrating clinical phenotype, history, and symptoms aids in identifying high-risk individuals for thyroid evaluation.
