Resumen
Objetivo: Evaluar la prevalencia de hipotiroidismo subclínico en pacientes con vitíligo tratados en un centro de referencia de dermatología en la Amazonía, describiendo sus características sociodemográficas, clínicas y de laboratorio. Métodos: Se realizó un estudio cuantitativo, descriptivo y transversal mediante el análisis de historias clínicas físicas y electrónicas de pacientes con diagnóstico de vitíligo e hipotiroidismo subclínico, tratados entre agosto de 2024 y abril de 2025 en un centro de referencia de dermatología especializado en la Amazonía. Los datos se analizaron mediante estadística descriptiva, con frecuencias absolutas y relativas. Resultados: Se evaluaron 188 historias clínicas y se incluyeron siete pacientes; el 57,1% eran mujeres y el 100% eran mestizos. Todos los pacientes presentaron niveles elevados de TSH con T4 libre normal y el 42,9% fueron positivos para anti-TPO. Se observó deficiencia de vitamina D en el 42,9% de los casos, además de comorbilidades como diabetes mellitus e hipertensión arterial. Ningún paciente estaba siendo tratado por hipotiroidismo subclínico. Conclusión: Los hallazgos resaltan la importancia del cribado de la función tiroidea en pacientes con vitíligo, especialmente en regiones con bajo nivel socioeconómico y acceso limitado a servicios de salud, como la Amazonía.
