초록
한국인은 D 음성자가 0.15%로 극히 드문데, 이중 약 15-17%가RHD 유전자 검사에 의해 DEL형으로 재 분류될 것이다. 향후 이들 DEL형 혈액제제는 D음성 환자에게 공급되지 않을 전망이므로 D음성 재고는 감소하고, DEL형 재고는 상대적으로 증가할 전망이다. 따라서, 이러한 한국에서의 상황을 고려한 새로운 수혈전략이 필요하게 되었다. 이에 본 종설에서는 가임기 여성 여부, 항-D 항체 보유 여부, 그리고 Asia type DEL형 유무를 고려한 보다 세분화된 수혈전략에 대해 논의하였다.
Abstract
The prevalence of RhD-negative individuals in the Korean population is approximately 0.15-0.30% and the supply of RhD-negative blood often faces potential shortage. Furthermore, 15-17% of serologically RhD-negative Korean individuals were revealed to be DEL variants and should be treated as RhD-positive when being considered as blood donors. This change is expected to result in a further shortage of RhD-negative blood supply, whereas surplus DEL variant blood stock is created. Therefore, it is now required to amend blood donation and supply policies, and transfusion strategies. In this review, a new transfusion strategy for patients with RhD-negative or variant blood in Korea is discussed, with particular interest in women of child-bearing age, patients with anti-D, and Asia type DEL (c.1227G>A) variants.
