The article, 'hematopoietic progenitor cells collection in pediatric patients with brain tumor' (spinola 2016), describes a series of 19 pediatric patients with brain tumors who underwent hematopoietic progenitor cell collections with spectra optia (n=10) and cobe spectra (n=9).The study was done to analyze the efficacy and safety of hematopoietic progenitor cells (hpc) collections by leukapheresis in pediatric patients with brain tumors."between 2003 and 2014, we collected hpc from 19 children (12 boys/7 girls), median age at the diagnosis of 5 years old (<1¿15 years old) and weight of 16.8 kg (6.7¿42).Diagnoses were medulloblastoma (n510), primitive neuroectodermal tumor (n55), atypical teratoid rhabdoid tumor (n53) and secreting germ cell tumor (n51).All patients performed leukapheresis by a central venous catheter, at the fifth day of mobilization with g-csf (median dose 11.7 mg/kg/day), 9 of them with cobe spectra and 10 with spectra optia.The anticoagulant used was acd-a, ratio of 14:1 or acd-a plus heparin, ratio 25:1.The tubing set was primed with a compatible, irradiated, leukodepleted and hematocrit adjusted packed red cells for all children <30 kg (n517).A median of 1.5 (1¿3) leukapheresis per patient was performed with an average of 3 (1.5¿5.4) blood volumes processed; 3 children did a second mobilization and one additional leukapheresis.The median number of cd341 cells collected was 4.6 3 106/kg (0.18¿22.6) of patient body weight; 12 children collected for a tandem transplant.The median time between cell collection and infusion was 3 (0.6¿9.1) months." adverse events occurred during the study: - 3 patients suffered from citrate toxicity, which consisted of perioral paresthesias and one had vomiting.Despite the prophylactic calcium perfusion administered at the beginning of the leukapheresis, an adjusted dose of oral calcium gluconate was immediately given to these children and all had their symptoms resolved.Exact details (patient information and outcome, platform with which the events are associated) regarding the patients with adverse events were not provided in the article, therefore this report is being provided as a summary of the events.The disposable set is not available for return because it was discarded by the customer.

Investigation: per the article, "the separator spectra optia was used with the mnc protocol, which includes an automatic interface management system and collection cycles being triggered without operative intervention.Until (b)(6) 2013, they used citrate at a constant ratio; after an adverse event during a leukapheresis in a low weight pediatric patient (multiple clots in the tubing set), they decided to perform in all children with less than 30 kg a citrate ramping.The anticoagulant used was acd-a, ratio of 14:1 or acd-a plus heparin, ratio 25:1.This anticoagulation method consists of processing the patient¿s blood volume with a ratio of 1:8 and gradually progressing to 1:14.During this anticoagulation phase, a 10% calcium gluconate 1 ml/kg was given intravenously for one hour to prevent hypocalcemia.The choice of citrate alone or in combination with heparin was based on a careful individual, case by case, risk benefit analysis.Children with increased bleeding risk, past history of moderate to severe hemorrhagic events, recent central nervous system surgery (<3 months prior leukapheresis) and peripheral platelet count <100 x 10^3/ml were considered for citrate alone." according to therapeutic apheresis: a physician's handbook, adverse events occur during therapeutic procedures with a frequency of 4.8%.Some of the most common reactions include fever, urticaria, hypocalcemic symptoms, pruritus, dyspnea, tachycardia, and mild hypotension.Transient hypocalcemia associated with apheresis is usually well tolerated.Symptoms often show as paresthesia (tingling) but patients may also experience unusual taste, nausea, lightheadedness, shivering, and tremors.Severe hypocalcemia may also cause muscle contractions and can progress to tetany and seizures if hypocalcemia escalates and is not corrected.The optia essentials guide advises the operator of possible adverse effects of apheresis procedures and to be prepared to take appropriate action should any reactions occur.Some previously reported reactions are: ¿ anxiety ¿ headache ¿ light-headedness ¿ digit and/or facial paresthesia ¿ fever ¿ chills ¿ hematoma ¿ hyperventilation ¿ nausea and vomiting ¿ syncope (fainting) ¿ urticaria ¿ hypotension ¿ allergic reactions the customer did not provide the lot number pertaining to this event, therefore a device history record (dhr) search could not be conducted for this specific incident.All lots must meet acceptance criteria before release.Root cause: a definitive root cause for the reported citrate reactions could not be determined.These reactions occur due to decreased ionized calcium in circulation as a result of exogenous citrate administered during the apheresis procedure and are influenced by patient physiology, the patient's disease state, the rate of ac infusion, the citrate contents in the replacement fluid, and/or the length of the procedure.These symptoms may be treated with oral or intravenous calcium supplements or by adjusting the ac infusion rate.

This is a retrospective data analysis of 19 children underwent hpc collection between 2003 and 2014, 12 boys and 7 girls.The median age at the leukapheresis was 5 years old (range, <1¿15 years old) and median weight of 16.8 kg (range, 6.7-42 kg); 17 patients had less than or equal to 30 kg and three of them less than or equal to 10 kg.A request for specific patient information is not feasible.
