The Italian Registry of Pediatric Therapeutic Apheresis: a report on activity during 2005.

The results of the 2005 Survey of the Italian Society for Apheresis and Cell Manipulation (SIdEM) reporting on the pediatric procedures carried out in 18 Italian Apheresis Units are presented here. Utilizing a standardized questionnaire, the survey collected data on techniques, types of blood separators, clinical indications, and adverse events. A total of 1,693 apheresis procedures were carried out in 355 pediatric patients: 219 plasma-exchange, 291 peripheral blood stem cell collections, 791 extracorporeal photochemotherapy (ECP), 265 LDL-apheresis, 71 erythro-exchange, 9 cytoreductive apheresis, 47 immunoadsorption sessions. Adverse events were registered in 94 procedures (5.6%), most of which of mild entity, e.g., insufficient flow rate (50.0%) and symptomatic hypocalcemia (24.4%). Our data indicate that all types of apheresis procedures can be safely carried out in children. ECP, utilized primarily for the treatment of graft versus host disease (GvHD) and rejection of solid organ transplantation, are burgeoning procedures in pediatric patients, whereas plasma exchange, which is a common treatment in adults, is infrequently utilized in pediatric medicine.
