Summary
Vitiligo patients have a higher risk of thyroid disease, especially those with specific clinical features. A targeted screening approach based on patient phenotype can improve diagnosis and reduce unnecessary testing.
Area of Science:
- Dermatology
- Endocrinology
- Immunology
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 examine how clinical and phenotypic characteristics influence thyroid disease risk.
Main Methods:
- Narrative review of existing literature.
- Analysis of epidemiological data.
- Examination of clinical and phenotypic predictors of thyroid disease.
Main Results:
- Specific features like nonsegmental vitiligo, acral involvement, female sex, extensive disease, and family history increase thyroid disease risk.
- Thyroid autoantibodies and subclinical hypothyroidism are common findings in vitiligo patients.
- Thyroid disease can precede or follow vitiligo onset.
Conclusions:
- A 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 individualized thyroid evaluation.
