Therapeutic plasma exchange has been widely employed by clinicians for removal of the toxic constituents from plasma by filtration of whole blood and subsequent removal of plasma and reinfusion of cellular components along with a replacement fluid. It has become an accepted therapeutic modality in paediatric patients for numerous indications including but not limited to renal transplant, haemolytic uremic syndrome and Guillain Barre Syndrome. But, data on safety and efficacy are mainly derived from studies in the adult population with very limited data available in the paediatric age group. However, it is technically challenging in children due to their small circulating volume. This study discusses the clinical indications, efficacy, and safety of therapeutic plasma exchange in paediatric population.
We retrospectively reviewed the data of children (up to 18 years of age) who underwent TPE between January 2017 and March 2019 at our Hospital. Main features of the TPE procedures i.e. frequency of TPE, site of vascular access, type of replacement fluid used, instrument used, plasma volume processed, priming of the circuit, adverse events if any and outcome of the patients were analysed.
A total of 114 procedures were performed on these 24 patients. Fifteen patients with Category I indication showed good clinical outcome in terms of attainment of target ABO titre and/or decrease in the donor specific antibody. TPE is an effective therapeutic option in selected paediatric disorders. Our series of data on TPE procedures from paediatric perspective has shown safety and efficacy of the therapy.
治疗性血浆置换已被临床医生广泛应用,通过过滤全血去除血浆中的毒性成分,随后去除血浆并将细胞成分与置换液一起回输。它已成为儿科患者中一种被认可的治疗方式,用于多种适应症,包括但不限于肾移植、溶血尿毒综合征和吉兰 - 巴雷综合征。但是,关于安全性和有效性的数据主要来自成人研究,儿科年龄组的数据非常有限。然而,由于儿童循环血量少,在儿童中进行该操作在技术上具有挑战性。本研究讨论了治疗性血浆置换在儿科人群中的临床适应症、疗效和安全性。
我们回顾性分析了2017年1月至2019年3月在我院接受治疗性血浆置换(TPE)的18岁及以下儿童的数据。分析了TPE操作的主要特征,即TPE的频率、血管通路部位、使用的置换液类型、使用的仪器、处理的血浆量、管路预充、是否有不良事件以及患者的结局。
这24例患者共进行了114次操作。15例I类适应症患者在达到目标ABO滴度和/或供体特异性抗体降低方面显示出良好的临床结局。TPE是某些儿科疾病的有效治疗选择。我们从儿科角度关于TPE操作的一系列数据显示了该治疗的安全性和有效性。
