Therapeutic plasma exchange in non-hematooncological disorders in pediatrics: A single center experience.

The use of therapeutic plasma exchange in the pediatric age group is mostly based on retrospective, single-center experiences. The decision to implement apheresis in pediatric patients is usually adopted from the results of studies on adult patients. In order to expand the limited data on pediatric TPE in general and non-hematooncological disorders in particular, we retrospectively evaluated TPE experience in pediatric patients who underwent the procedure for reasons other than hematooncological disorders. A total of 160 sessions in 34 patients (21 females and 13 males) with a median age of 7 (1-17) were analyzed. Most of the patients had sepsis and organ failure (12 patients, 35 procedures). In only one patient (2.9%) with methyl malonic aciduria (MMA) and sepsis, the procedure was terminated due to a grade 3 allergic reaction. Among the study cohort, 4 patients passed away. No patient died due to complications of TPE. The relatively low discontinuation rate and the lack of procedure-related mortality indicate that TPE is generally well tolerated in the pediatric age group similar to the adult population. However, since there are very limited evidence-based data on TPE use, especially in the pediatric age group, retrospective case series may also be helpful for clinicians in the decision-making process.
