Assessing safety and efficacy of therapeutic plasma exchange in pediatric patients: A single-center experience.

Abstract

INTRODUCTION: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.METHOD: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.RESULTS AND CONCLUSION: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.
