ABSTRACT
Objetivo: Evaluar la expresión génica del gen IP-10 en pacientes con lupus eritematoso sistémico (LES) y su posible relación con la actividad de la enfermedad. Pacientes y métodos: El estudio incluyó 120 pacientes diagnosticados con LES y 30 controles sanos. Se investigó la expresión génica relativa de IP-10 con el método fold change, la cual fue correlacionada con el nivel de actividad lúpica evaluado con el instrumento SLEDAI 2-K. Resultados: Se encontraron diferentes niveles en la expresión génica de IP-10 relacionada con la actividad lúpica (p =<0,001). Estos fueron mayores en los pacientes con actividad grave respecto a aquellos sin actividad, baja y moderada. El incremento en la expresión génica del grupo con actividad grave fue significativo con un fold change de tres. Conclusión: El incremento significativo en la expresión génica relativa IP-10 puede ser un marcador de actividad lúpica grave.(AU)
Objectives: To evaluate IP-10 gene expression in patients with SLE, and its possible relationship with disease activity. Patients and methods: This study included 120 patients diagnosed with SLE and 30 healthy controls. The relative gene expression of IP-10 was investigated with the Fold Change method, which was correlated with the level of lupus activity evaluated with the SLEDAI 2-K instrument. Results: Different levels of gene expression were found according to the SLE activity (p =<0.001). IP-10 gene expression levels were higher in patients with severe activity than in those with no activity, low activity, and moderate activity. The increase in gene expression in the severe activity group was significant with a Fold Change of 3. Conclusion: The significant increase in relative gene expression IP-10 may be a marker of severe lupus activity.(AU)
