Medoff与Barbero氏,Burrell氏早在25年前就报导过嗜酸性细胞增多症常发生于早产儿中。Xanthou氏于1970年肯定了这一发现。过去关于这类嗜酸性细胞增多症与皮质醇浓度有关的学说,目前看来是不可靠的,但尚未提出新的与之有关的因素或病因学。本文的目的在于确定早产新生儿中嗜酸性细胞增多症的发生率和探究与这种嗜酸性细胞增多症有关的因素。 Medoff and Barbero’s, Burrell reported as early as 25 years ago that eosinophilia occurs frequently in preterm infants. Xanthou affirmed this discovery in 1970. In the past, the doctrine concerning the association of such eosinophilia with cortisol concentrations appeared to be unreliable at this stage, but no new pertinent factors or etiologies have been proposed. The purpose of this article is to determine the incidence of eosinophilia in premature neonates and to explore the factors associated with this eosinophilia.
