Actividad hemolitica del complemento (CH 50) en pacientes con sospecha clinica de enfermedad autoinmune / Annual reports 1997

En el presente estudio determinamos la actividad hemolítica del complemento (CH50) en 180 pacientes de ambos sexos remitidos al laboratorio de Inmunología Humoral con sospecha clinica y y/o diagnóstico de LES u otra patología autoinmune. Treinta de los 180 pacientes presentaron, además, pedido médico para la determinación del nivel de C3 y 15 la presencia de ANA. El 38,8 (70/180) mostró niveles disminuidos de CH50. En los 30 en que se determinó el nivel de C3, se encontraron valores por debajo de lo normal, tanto de C3 como CH50 y en 15 de éstos se detectaron resultados altamente positivo de ANA. En base a estos datos podemos concluir que pacientes con procesos autoinmunes presenten valores de la actividad hemolitica del complemento disminuida, siendo e CH50 un método simple para evaluar la funcionalidad del sistema del complemento y que podría ser muy útil en el diagnóstico de enfermedades autoinmunes, evaluaci2n de la severidad de la enfermedad y eficacia de la terapéutica
