BACKGROUND/AIM: Anemia in patients suffering from end-stage renal failure is currently treated with Erythropoiesis-Stimulating Agents (ESA). This treatment needs sufficient iron supplementation to avoid an inadequate dosage of ESA. Nowadays modern analytical instruments allow to accurately calculate the content of Hemoglobin (Hb) in reticulocytes (CHr), that can be used as a guide for prescribing patients with the appropriate amount of iron.
Patients, undergoing hemodialysis, were retrospectively selected from the database and were divided in two groups: group A received intravenous (IV) iron and subcutaneously ESA, and their dosages were adjusted on the basis of the following parameters: Hb, Mean corpuscular haemoglobin (MCH), CHr with consequent MCH/CHr ratio and reticulocyte count determined by the ADVIA 120 Hematology System of Siemens; group B patients were administered IV iron and ESA monitoring iron storage, Hb and ferritin. The aforementioned parameters and the administered amount of iron and ESA were monitored at baseline, four and eight months from the begining of the study.
For ESA supplementation, no difference was observed between the groups at the various observed times. Despite similar Hb levels, the patients of group A needed significant lower doses of IV iron (-57.8%) avoiding risks of organ toxicity and obtaining consequent cost saving of nearly 1 €/patient/month.
The use of CHr and its related parameters allows the avoidance of overdosage of IV iron, which can potentially damage organs, and the reduction of health care direct and indirect costs.
背景/目的:目前,终末期肾衰竭患者的贫血采用促红细胞生成素(ESA)进行治疗。这种治疗需要充足的铁补充剂,以避免ESA剂量不足。如今,现代分析仪器能够准确计算网织红细胞中的血红蛋白(Hb)含量(CHr),可将其作为为患者开具适量铁剂的指导依据。
从数据库中回顾性选取接受血液透析的患者,并将其分为两组:A组接受静脉注射铁剂和皮下注射ESA,其剂量根据以下参数进行调整:Hb、平均红细胞血红蛋白含量(MCH)、CHr以及由此得出的MCH/CHr比值,还有通过西门子ADVIA 120血液学系统测定的网织红细胞计数;B组患者接受静脉注射铁剂和ESA治疗,同时监测铁储存、Hb和铁蛋白。在研究开始时、四个月和八个月时监测上述参数以及铁剂和ESA的给药量。
在各个观察时间点,两组在ESA补充方面未观察到差异。尽管Hb水平相似,但A组患者所需的静脉注射铁剂剂量显著更低(-57.8%),避免了器官毒性风险,并因此实现了每位患者每月近1欧元的成本节约。
使用CHr及其相关参数可避免静脉注射铁剂过量,而过量铁剂可能会损害器官,还能降低医疗保健的直接和间接成本。
