Fatiga en pacientes con lupus eritematoso sistémico: datos del registro RELESSAR prospectivo
Resumen
Introducción: la fatiga es una manifestación frecuente y poco comprendida del lupus eritematoso sistémico (LES) presente en hasta el 86% de los pacientes y con impacto negativo en la calidad de vida. Su evaluación sistemática sigue siendo una necesidad no cubierta en la práctica clínica. Objetivos: evaluar el grado de fatiga en pacientes con LES mediante una escala visual análoga (EVA), y analizar su asociación con variables sociodemográficas y clínicas. Materiales y métodos: estudio transversal basado en los datos de la visita basal del registro RELESSAR prospectivo de la Sociedad Argentina de Reumatología. Se incluyeron pacientes ≥18 años con diagnóstico de LES ≤5 años. Se consideró fatiga significativa una EVA ≥4. Se realizaron análisis univariados y multivariados para determinar factores asociados. Resultados: se incluyeron 198 pacientes; el 53% presentó fatiga ≥4. En el análisis multivariado, la fatiga se asoció con la actividad de la enfermedad (SLEDAI-2K) (OR 1,18; IC 95% 1,10-1,28; p<0,001) y con el tiempo al diagnóstico (OR 2,08; IC 95% 1,35-3,40; p=0,002). También se observó mayor frecuencia de hospitalizaciones y peor valoración global. Conclusiones: la fatiga es prevalente en pacientes con LES y se asocia con mayor actividad, por lo cual se destaca la necesidad de su evaluación sistemática.Citas
