Estudio longitudinal de anticuerpos anticitoplasma de neutrófilos en pacientes con anemia drepanocítica Longitudinal study of antineutrophil cytoplasmic antibodies in patients with sickle cell anemia

Abstract

Se realizó un estudio longitudinal para detectar anticuerpos anticitoplasma de neutrófilos (ANCA) en 13 pacientes con anemia drepanocítica en crisis vasooclusiva y en estado basal, mediante un método de inmunofluorescencia indirecta. Del total de 34 muestras de suero obtenidas, 16 fueron en crisis vasooclusiva y en 12 de ellas, correspondientes a 10 pacientes, se demostró la presencia de p-ANCA. En el resto de las muestras en crisis vasooclusiva y en estado basal no se observó la presencia de p-ANCA o c-ANCA. Los resultados obtenidos sugieren la posible participación de los p-ANCA en el daño isquémico, así como la importancia de su medición en el diagnóstico de las crisis vasooclusivas (CVO) en los pacientes con anemia drepanocítica (AD)A longitudinal study was made to detect antineutrophil cytoplasmic antibodies (ANCA) in 13 patients with sickle cell anemia in vasocclusive crisis and basal state by using an indirect immunofluorescence method. Of 34 serum samples, 16 were in vasocclusive crisis and 12 of them corresponding to 10 patients revealed the presence of p-ANCA. Neither p-ANCA nor c-ANCA was observed in the rest of the samples taken in vasoclussive crisis and in basal state. The results achieved signaled a possible involvement of p-ANCA in ischemic damage as well as the importance of their measurement in the diagnosis of vasocclusive crisis in patients with sickle cell anemia
