Despite their transfusion-independence, non-transfusion-dependent thalassemia (NTDT) patients experience a variety of serious clinical complications that require prompt and comprehensive management. Transfusion therapy may still be an important part of management of this disease, in cases of acute stress, to support growth and development in childhood, or to prevent clinical morbidities stemming from ineffective erythropoiesis or hemolytic anemia. Although splenectomy is associated with improvements in hemoglobin levels, it leads to several short- and long-term adverse events, warranting caution in application of this intervention. Fetal hemoglobin induction therapy has been evaluated in non-randomized studies, with benefits extending beyond hematologic improvements to lowering morbidity risk. Effective and safe iron chelation therapy is now available for NTDT patients in whom iron overload develops, irrespective of transfusions, due to increased intestinal absorption, ultimately leading to clinically high iron burden levels and subsequent morbidity. Optimal management of NTDT patients requires a holistic approach targeting all hallmarks of the disease to ensure favorable patient outcomes.
尽管非输血依赖型地中海贫血(NTDT)患者无需输血,但他们仍会经历多种严重的临床并发症,需要及时、全面的管理。在急性应激、儿童生长发育或预防无效红细胞生成或溶血性贫血引起的临床并发症的情况下,输血治疗可能仍然是该疾病管理的重要组成部分。尽管脾切除术可提高血红蛋白水平,但会导致多种短期和长期不良事件,因此在应用这种干预措施时需谨慎。非随机研究评估了胎儿血红蛋白诱导治疗,其益处不仅限于血液学改善,还降低了发病风险。对于因肠道吸收增加而发生铁过载的 NTDT 患者,无论是否输血,现在都可提供有效且安全的铁螯合治疗,最终导致临床高铁负荷水平和随后的发病。NTDT 患者的最佳管理需要采用整体方法针对疾病的所有特征进行治疗,以确保患者获得良好的预后。
