Hyperhemolysis is a life-threatening condition of exaggerated hemolysis of red blood cells which occurs in patients receiving chronic transfusion therapy. We present a 19-year-old male with the β-thalassemia major with an episode of hyperhemolysis. Hemolysis was initially unresponsive to immunosuppression but responded after the addition of eculizumab. Several weeks after stabilization, hemolysis returned; which was also managed with immunosuppression and eculizumab. Hyperhemolysis presents significant challenges in β-thalassemia due to the underlying dysfunctional erythropoiesis and transfusion dependence. Aggressive immunosuppression combined with eculizumab successfully slowed the hemolysis and allowed for the resumption of transfusions.
高溶血是一种危及生命的红细胞过度溶血状态,发生于接受慢性输血治疗的患者。我们报告一名19岁重型β地中海贫血男性患者发生了一次高溶血发作。溶血最初对免疫抑制无反应,但在添加依库珠单抗后有反应。病情稳定数周后,溶血复发,同样通过免疫抑制和依库珠单抗进行处理。由于潜在的红细胞生成功能障碍和输血依赖,高溶血在β地中海贫血中带来了重大挑战。积极的免疫抑制联合依库珠单抗成功减缓了溶血,并使输血得以恢复。
