RESUMEN
La psoriasis, en la actualidad, se considera una enfermedad sistémica, autoinmune, que condiciona un microambiente inflamatorio mediado por diversas citocinas, principalmente TNF-α, IL-20 e IL-17. La piel es el principal órgano de choque, lo que induce una queratinopoyesis acelerada que culmina en la expresión clínica característica. Por su carácter sistémico, se ha observado que los pacientes con esta dermatosis tienen mayor prevalencia de comorbilidades, entre ellas el síndrome metabólico. Un metaanálisis demostró que los pacientes con psoriasis tienen el doble de riesgo para desarrollar síndrome metabólico que la población en general. En la población mexicana no existen estudios que demuestren dicho comportamiento.
Objetivo: Determinar la prevalencia de síndrome metabólico en pacientes adultos con psoriasis.
Material y métodos: Se reclutaron pacientes con diagnóstico clínico e histológico de psoriasis. Se evaluaron clínicamente y se determinó si tenían síndrome metabólico de acuerdo a los criterios del NCEP ATP III. La extensión y severidad de la psoriasis se evaluó con el Psoriasis Area and Severity Index (PASI).
Resultados: Se estudiaron 39 pacientes con psoriasis en placas de la Consulta Externa del Centro Dermatológico «Dr. Ladislao de la Pascua». El 43.5% (IC95%, 28-60%) de los mismos fueron diagnosticados con síndrome metabólico. Al comparar pacientes con y sin síndrome metabólico, se encontraron diferencias estadísticamente significativas en la circunferencia abdominal, nivel de triglicéridos y presión arterial (p ‹ 0.05).
Conclusiones: Por el tamaño de muestra y su homogeneidad en relación a las características de la psoriasis no fue posible determinar con precisión la prevalencia del síndrome metabólico en población mexicana. Este estudio servirá de antecedente para estudios epidemiológicos que exploren la asociación entre psoriasis y síndrome metabólico.
