Abstract

Infantile pyknocytosis is a rare, self-limited, hemolytic condition of unknown pathogenesis. It is diagnosed when a neonate with Coombs-negative hemolytic anemia has abundant pyknocytes and a characteristic clinical course after other hemolytic disorders has been excluded. Previous reports suggest that transfusions might be avoidable in this condition by administering recombinant erythropoietin. We cared for a patient with this disorder where we employed novel diagnostics and therapeutics. Despite these, and a good outcome free of transfusions, we continue to consider the condition to be idiopathic.

婴儿胞缩症:末潮CO, %Micro-R测量,下一代测序,和达贝泊汀避免输血。
婴儿胞缩症是一种罕见的、自限性的溶血性疾病,其发病机制尚不清楚。当排除其他溶血性疾病后,coombs阴性溶血性贫血的新生儿有大量的pyknocytes并有特征性的临床病程时诊断为coombs。以前的报告表明,在这种情况下,通过给予重组红细胞生成素可以避免输血。我们照顾一个患有这种疾病的病人,我们采用了新的诊断和治疗方法。尽管如此,并且无输血的良好结果,我们仍然认为这种情况是特发性的。
