Appropriate blood transfusions can both prevent and treat serious complications related to sickle cell disease (SCD), but inevitably lead to iron overload and its complications in terms of morbidity and mortality. Transfusion history and serial serum ferritin level assessments are convenient and cost-effective measures for monitoring iron overload in SCD. Monitoring and treatment of patients with SCD-related iron overload lags behind the standards of care for b-thalassaemia. Data from the EPIC trial suggest suboptimal iron chelation in SCD, highlighting the need to carefully monitor iron levels and initiate iron chelation therapy to avoid serious clinical sequelae. Deferasirox is effective and well tolerated in patients with SCD, including paediatric patients. Patient compliance is, however, important for effectiveness of iron chelation therapy.
适当的输血既可以预防也可以治疗与镰状细胞病(SCD)相关的严重并发症,但不可避免地会导致铁过载,并由此导致发病率和死亡率方面的并发症。输血史和连续血清铁蛋白水平评估是监测 SCD 中铁过载的便捷且具有成本效益的措施。SCD 相关铁过载的监测和治疗落后于β-地中海贫血的护理标准。EPIC 试验的数据表明 SCD 中的铁螯合作用并不理想,这突出表明需要仔细监测铁水平并开始铁螯合治疗,以避免严重的临床后果。地拉罗司在 SCD 患者中有效且耐受良好,包括儿科患者。然而,患者的依从性对于铁螯合治疗的有效性很重要。
