Duffy血型系统有6个抗原,Fya和Fyb是其中常见的2个抗原,由于Fya在中国人群中属高频抗原,因此产生的抗-Fya并不常见,而由此导致的新生儿溶血病更为罕见。报告1名稀有血型Fy(a-b+)孕妇因输血产生抗-Fya并导致新生儿溶血病,本例报道在国内尚属首次。
Duffy blood system has six antigens, Fya and Fyb are two common antigens, because Fya is a high frequency antigen in the Chinese population, resulting in anti-Fya is not common, and the resulting neonatal hemolytic disease more Rare. This report is the first in our country to report a rare blood group of Fy (a-b +) pregnant women who develop anti-Fya due to blood transfusions and cause neonatal hemolytic disease.
