Abstract
BACKGROUND Transplantation of peripheral blood stem cells (PBSCs) mobilized by cytokines is increasingly applied to treat patients with hematologic diseases, such as lymphoma, multiple myeloma, leukemia, etc. Successful hematopoietic stem cell transplantation (HSCT) increasingly depends on the collection of hematopoietic stem cells (HSCs) from peripheral blood. Peripheral vein (PV) is the most common type of blood access. When the blood vessels are not well filled and the blood flow is insufficient, the machine will appear repeated low pressure alarm or pipeline coagulation, which seriously affects the collection efficiency. A peripheral artery (PA) is utilized for drawing blood, while a peripheral vein is used for blood return, that is a way to perform apheresis. The advantages of PA are that it ensures adequate extracorporeal circulation blood flow, stable blood flow rate, simple operation, and relatively low price. However, there are very few studies on the efficacy of peripheral arterial access for HSCs collection. Therefore, this retrospective study was conducted to assess the effectiveness of PA and PV access for PBSCs collection. METHODS We performed a retrospective analysis of 150 apheresis procedures on 26 patients and 95 healthy donors collected by PV or PA access from March 1, 2020 to March 1, 2021. We compared the CD34+ cell count, collection efficiency (CE), duration of processing a single blood volume, number of low-pressure alarms, average blood flow rate and number of punctures between the two groups. Also, we analyzed adverse events. RESULTS There was no significant difference in the quality of apheresis blood components between the PA group and the PV group. The CD34+ cells collected was 274.16 ± 216.31 × 106 in the PV group and 246.63 ± 127.94 × 106 in the PA group. The CE in the PA group was 49.50 ± 9.88%, higher than 42.39 ± 14.62% in the PV group. The duration of processing a single blood volume was 90.67 ± 15.35 min in the PV group and 79.68 ± 10.28 min in the PA group. The number of low-pressure alarms in the PA group was 0.38 ± 0.98, <2.42 ± 1.76 in the PV group, and the average blood flow rate in the PA group was 59.27 ± 2.18, higher than 54.21 ± 3.41 in the PV group. The difference was statistically significant (P < .05). The Number of punctures was 1.35 ± 0.75 in the PA group and 1.41 ± 1.01 in the PV group. There was no statistically significant difference. CONCLUSION Peripheral artery is a safe, reliable, economical, convenient, and fast vascular access, which opens a new way to the establishment of vascular access for PBSCs collection.

Abstract
BACKGROUND Autologous stem cell transplantation remains an integral treatment tool for certain childhood malignancies. In children, a central venous catheter is typically necessary to provide adequate flow rates for preparative apheresis. In this study, the feasibility and efficiency of collecting CD34+ cells via an indwelling Hickman catheter, preimplanted for chemotherapy, instead of placing an additional temporary central venous catheter was evaluated. STUDY DESIGN AND METHODS Forty-eight pediatric leukaphereses for autologous hematopoietic stem cell transplantation using Spectra Optia MNC, Version 3.0 were reviewed. We compared preimplanted Hickman catheters with a temporary Shaldon catheter, inserted for apheresis. Apheresis was considered successful if a dose of 2 × 106 CD34+ peripheral blood stem cells/kg BW was achieved. RESULTS In 43 (89.6%) of the 48 patients, a Hickman catheter was used for leukapheresis. Only 5 patients (10.4%) received a temporary Shaldon catheter. In both groups, apheresis was performed without apparent adverse reactions. The dose of collected CD34+ peripheral blood stem cells was 12.7 × 106 (range, 2.3-70.7 × 106 ) cells/kg BW in the Hickman group and 16.2 × 106 (range, 3.8-48.4 × 106 ) cells/kg BW in the Shaldon group, showing no statistically significant difference (p = 0.58). In both groups, the primary endpoint of a minimal CD34+ cell concentration of 2 × 106 cells/kg BW was achieved at a maximum of two leukapheresis sessions. Apheresis efficacy was further confirmed by the collection efficiency of 40.2% in the Hickman group and 27.8% in the Shaldon group (p = 0.32). CONCLUSION These data indicate the reliable feasibility and efficacy of mobilized apheresis via an indwelling Hickman catheter. In light of this, the routine insertion of a dialysis catheter for the purpose of leukapheresis should be critically reconsidered.

Abstract
INTRODUCTION Autologous peripheral blood hematopoietic progenitor cell collection (A-HPCC) in children typically requires placement of a central venous catheter (CVC) for venous access. There is scant published data regarding the performance and safety of femoral CVCs in pediatric A-HPCC. METHODS Seven-year, retrospective study of A-HPCC in pediatric patients collected between 2009 and January 2017. Inclusion criteria were an age ≤ 21 years and A-HPCC using a femoral CVC for venous access. Femoral CVC performance was examined by CD34 collection rate, inlet rate, collection efficiency (MNC-FE, CD34-FE), bleeding, flow-related adverse events (AE), CVC removal, and product sterility testing. Statistical analysis and graphing were performed with commercial software. RESULTS A total of 75/119 (63%) pediatric patients (median age 3 years) met study criteria. Only 16% of children required a CVC for ≥ 3 days. The CD34 collect rate and CD34-FE was stable over time whereas MNC-FE decreased after day 4 in 80% of patients. CD34-FE and MNC-FE showed inter- and intra-patient variability over time and appeared sensitive to plerixafor administration. Femoral CVC showed fewer flow-related AE compared to thoracic CVC, especially in pediatric patients (6.7% vs. 37%, P = 0.0005; OR = 0.12 (95%CI: 0.03-0.45). CVC removal was uneventful in 73/75 (97%) patients with hemostasis achieved after 20-30 min of pressure. In a 10-year period, there were no instances of product contamination associated with femoral CVC colonization. CONCLUSION Femoral CVC are safe and effective for A-HPCC in young pediatric patients. Femoral CVC performance was maintained over several days with few flow-related alarms when compared to thoracic CVCs.

Abstract
Collection of PBSC by leukapheresis requires one venous access (VA) for inflow and one for outflow. The use of implantable venous access devices (IVAD) has never been reported in this setting. We retrospectively analyzed the use of IVAD for performing apheresis. The study was conducted between January 2000 and June 2005 on 64 patients (41 children) requiring intensification for treatment of a solid tumor. Mean body weight was 26 kg (range 8-91 kg) for a median age of 8.5 years (range 0.7-66 years). A total of 121 aphereses were performed (mean 1.89 apheresis/patient). The second VA was in a cubital vein in 84 procedures and was a temporary central VA in 31. Mean duration of apheresis was 3 h (range 30-274 min). Mean flow rate was 41.3 ml/min (range 12-85 ml/min). Mean collection rate was 59.2% for CD34+ cells and 70% for mononuclear cells. The total number of CD34+ cells collected was 2.5 x 10(6)/kg per apheresis, and 5.9 x 10(6)/kg per patient. Several complications occurred: one catheter-related sepsis (0.86%), four catheter occlusions (3.47%) and eight hemodynamic instabilities related to extracorporeal volume. Weight <10 kg is a risk factor for complication (P=0.0006). IVAD are effective and safe for PBSC collection. Placement of a second central VA (requiring general anesthesia for children) could be avoided.

Abstract
BACKGROUND The feasibility and complication rate of central venous totally implantable access ports (TIAP), used for delivering high-dose chemotherapy (HDC) with autologous stem cell transplantation, have not been fully investigated to date, due to the almost exclusive use of external catheters (EC) in this clinical setting. PATIENTS AND METHODS We retrospectively studied infectious and mechanical complications of 45 TIAP and 19 EC, in 64 children receiving HDC and autologous stem cell transplantation at the Centre Leon-Berard (Lyon) or at the oncology unit of Toulouse children hospital between January 1999 and December 2003. RESULTS From the beginning of intensification to 60 days after bone marrow transplantation, 7 catheter-related bloodstream infections (3/19 EC or 15.8% corresponding to 2.69 infections for 1000 days of observation; 4/45 TIAP or 8.9% corresponding to 1.38 infections for 1000 days of observation) and 2 local infections (1/45 TIAP; 1/19 EC) were reported. Seven cases of reversible obstruction (6/7 with TIAP) and no deep venous thrombosis were detected. In 7 cases, another venous access was required either for accidental removal (2 EC), catheter infection (2 TIAP), or admission to intensive care (2 TIAP, 1 EC). TIAP complication rate does not seem to be influenced by factors such as low weight, massive blood product transfusion or prolonged parenteral nutrition. In 8 children, TIAP were used for collection of hematopoietic progenitor cells. CONCLUSIONS The use of TIAPs appears as a safe and effective option for HDC. We found more mechanical complications but less infectious complications with TIAP than with EC. Nevertheless, results need to be validated prospectively in a larger study cohort.

Abstract
BACKGROUND Although the equimolecular mixture of oxygen and nitrous oxide (EMONO) seems a good choice to relieve procedure-related pain in children, it has not been evaluated for insertion of central venous catheters in children. To assess the safety and the effectiveness of this gas mixture for insertion of central venous catheters, we conducted a prospective observational study. PROCEDURE This study was performed by the "Centre National de Greffe de Moelle Osseuse." Procedure and inhalation characteristics, as well as pain evaluations and side effects, were reported. RESULTS Fifty central venous catheters were inserted in 50 consecutive children. Median age was 7 (range, 4-13) years. An anesthesiologist was responsible for delivering EMONO, and provided constant surveillance throughout the procedure. EMLA cream was applied 2 hr before EMONO inhalation. No associated drugs were used. All catheters were inserted by the same experienced physician in the operating theater. Median inhalation length was 5 min (range, 3-6) before starting catheter's insertion and 12 min (range, 9-25) for the total inhalation. Median procedural pain evaluations were 10 (range, 0-30) for children on a 0-100 visual analog scale (VAS). Minor side effects were observed during eight (16%) inhalations. These side effects were euphoria (14%), deep sedation (4%), nausea and vomiting (2%), hallucinations (2%). All side effects were transient and resolved within 5 min after removing the inhalation device. CONCLUSIONS This study which shows that EMONO is effective for insertion of central venous catheters in children and represents a simple and safe alternative to general anesthesia.

Abstract
Central venous catheters are frequently used in leukapheresis to provide high flow rates. The most common locations are the subclavian or jugular vein, but insertion-related complications and inadequate flow are frequent problems. Experience using femoral venous access is limited, because this has been discouraged due to the high incidence of infectious or thromboembolic complications. We evaluated the safety and efficacy of 108 short-term femoral venous dialysis catheters used for the collection of peripheral blood stem cells (PBSCs). All catheters were placed by a member of the dialysis unit, and they remained in situ for the days needed to reach the target number of CD34+cells. No prophylactic antibiotic or antithrombotic therapy was used. A total of 232 apheresis sessions was performed. The longest duration a catheter remained in situ was 5 days. Most of the patients finished the collection in one or two apheresis sessions. There were no thrombotic or infectious complications, and insertion-related complications or mechanical problems were minimal. Apheresis results were similar to those reported using subclavian or jugular venous access. The short-term use of femoral venous dialysis catheters appears safe and effective for PBSC collection, simplifying the procedure, improving patient comfort, and reducing cost.

Abstract
Peripheral blood stem cells (PBSC) harvest may be difficult in young children. Extracorporeal separator line priming by red blood cells is usually required to improve haemodynamic tolerance and efficacy of collection. We present our experience with 24 children weighing less than 15 kg treated between January 1997 and September 1999, in whom we tried to avoid systematic blood priming. The median age and weight at the time of apheresis were 2.4 years and 12 kg, respectively. A total of 48 PBSC were performed. When haemoglobin was less than 12 g/dl, packed red cells were transfused before collection (40% of aphereses). The median cell yield per apheresis was 7.1 (2.2-30.6)x10(6)/kg CD34(+) cells and 16.0 (3.3-44.3)x10(5) CFU-GM/kg. Initial collection failed in three cases. Four children required an additional haematopoietic progenitor mobilization. This procedure allowed PBSC collection without transfusion in 37.5% of children, and was safe (two serious and five mild transient side effects) and effective (median CD34(+) cells collected per child: 7.1 x 10(6)/kg (4.6-30.6) and CFU-GM: 15.1 x 10(5)/kg (4.7-44.3)). Despite their low weight, insertion of a femoral catheter was avoided in 43% of children.

Abstract
Peripheral blood stem cell (PBSC) harvesting in the smallest children (weight <10 kg) using separators is complicated by specific problems. The volume of the separation set exceeds 25% of the total blood volume and the vascular access is generally not sufficient. Therefore, a simple manual technique for PBSC harvesting was developed. Three children (6-9 kg), with newly diagnosed tumours were scheduled to be treated with three to six sequential courses of high-dose chemotherapy, each followed by PBSC support. PBSC harvests were started after mobilization using cyclophosphamide and G-CSF when the peripheral blood CD34+ cell count exceeded 50/microl. About 50 ml of blood was drawn from a venous catheter, injected into a transfer bag containing ACD-A, and centrifuged. The buffy coat obtained was pooled in a collection bag, remaining plasma and erythrocytes were immediately reinfused and a subsequent cycle started. From three to 13 cycles were performed in 1-3 days and 18.0-32.2 x 10(6) CD34+cells/kg were collected. We did not detect any bacterial contamination or any notable complications. Fifteen PBSC reinfusions have been performed to date, each with rapid engraftment taking between 7 and 13 days. Patients are in very good PR (18 months from diagnosis) or in CR (6 and 8 months). We can conclude that this procedure is feasible and safe.

Abstract
Between February 1995 and July 1999 25 pediatric patients (8 months to 14 years old) underwent peripheral blood stem cell transplantation (PBSCT) from an HLA-identical sibling donor. Diagnoses included ALL (17), non-ALL (6), and non-malignant disease (2). GVHD prophylaxis consisted of cyclosporine plus methotrexate (15), only cyclosporine (8), cyclosporine plus prednisone (1), or nothing (1). All donors (6 months to 41 years old) received G-CSF at 10 microg/kg/day subcutaneously for 4-5 days and on day 5 underwent large volume leukapheresis. Median number of CD34(+) and CD3(+) cells collected and infused was 6.9 x 10(6) (range 2.5-32.8) and 4.5 x 10(8) (0.5-22.1) per kg of recipient body weight respectively. Median time to achieve ANC >0.5 x 10(9)/l and platelets >20 x 10(9)/l was 10 and 12 days, respectively. Acute GVHD grade > or =II developed in 10 of 24 evaluable patients (42%). Probability of acute GVHD was 62%. Median time to discharge was 25 days (range 14-52). Among 20 evaluable patients, five (25%) developed chronic GVHD at day 100. Probability of chronic GVHD was 29% after 1 year post PBSC. At a median follow-up of 558 (9-2071) days, overall survival for the whole group is 68%. Probabilities of event-free survival, overall survival and relapse for patients with malignant hematological diseases are 53%, 59% and 24% at 5 years, respectively. This study has confirmed the feasibility and safety of mobilization and collection of PBSC products and the applicability of this procedure to the pediatric population, both donors and recipients. Studies including larger numbers of pediatric patients undergoing allogeneic PBSCT are warranted to determine the long-term outcomes of such procedures.

Abstract
An 8-F 24-cm-long apheresis catheter was placed in the basilic vein with imaging-guided percutaneous technique in 15 children undergoing leukapheresis for collection of autologous peripheral blood stem cells. There were no immediate or long-term complications. This is a low-morbidity procedure requiring minimal sedation that results in successful collection of peripheral blood stem cells and allows flow rates comparable to those with surgically placed central catheters.

Abstract
This paper presents a state-of-the-art review of using mobilized-peripheral blood progenitor cells (PBPC) for transplantation in children. Our own data and those from Medline searches and meeting reports, are analyzed and presented for the different sections that involve transplantation. Recommendations concerning the choice of mobilization regimens, venous access, priming of separator extracorporeal line, anticoagulation, and number of CD34+ cells to infuse for rapid engraftment are proposed. In the allogeneic setting, we analyze ethical and safety aspects of pediatric donor mobilization and collection. Data from the literature suggest that the use of cytokine-mobilized PBPC for allogeneic transplantation appears to be safe both for pediatric donors and patients leading a rapid hematopoietic engraftment with a similar incidence of acute graft-versus-host disease (GVHD). The high incidence of chronic GVHD and its management emerge as the most concerning aspect in allogeneic PBPC transplantation.

Abstract
Children with high risk malignancies are usually given permanent (Hickman-type) tunneled silicone rubber central venous catheters (silicone CVCs) for the administration of chemotherapy. In the past, these children received an additional short-term polyurethane dialysis CVC for stem cell apheresis. To avoid placement of an additional short-term CVC, we started in 1995 to use pre-existing silicone CVCs for PBPC harvests. From May 1996 to February 1999 we evaluated 165 harvests in 37 children and 14 young adults (16-28 years) treated with high-dose chemotherapy and stem cell support, comparing CD34+ cell harvest efficiency, catheter tolerability, and complications in three different approaches to vascular access. Pre-existing silicone CVCs (64%) or peripheral venous cannulae (15%) were the first choice for venous access. Only when these failed were polyurethane CVCs (21%) used. No significant difference was seen between these three groups, even after dividing the silicone CVC group (105 harvests in 32 patients) into three subgroups according to weight and age. The most frequent problems were citrate toxicity (n = 33), mechanical obstruction inside (n = 9) and outside the cell separator (n = 2), decreased draw line flow in silicone CVCs (n = 7), decreased draw line flow in peripheral venous cannulae (n = 6), and one occlusion in a polyurethane CVC. Pre-existing CVCs and peripheral venous cannulae functioned efficiently when used as a draw line in 79% of the apheresis procedures without significantly reducing single harvest efficiency or catheter tolerability. Consequently, the risks and costs associated with the placement of a dialysis CVC could be avoided in the majority of cases. Bone Marrow Transplantation (2000) 26, 781-786.

Abstract
Autologous peripheral blood progenitor cell (PBPC) transplantation frequently requires sequential placement and use of two separate central venous catheters: (1) a short-term, large-bore, stiff device inserted for leukapheresis, and after removal of that device, (2) a long-term, multi-lumen, flexible, Silastic catheter for administration of high-dose chemotherapy, re-infusion of hematopoietic cells, and intensive supportive care. We reviewed our recent experience with two dual-lumen, large-bore, Silastic multi-purpose ('hybrid') catheters, each of which can be used as a single device for both leukapheresis and long-term supportive care throughout the transplant process. Quinton-Raaf PermCath and Bard-Hickman hemodialysis/apheresis dual-lumen catheters were used as the sole venous access device in 112 consecutive patients who underwent autologous PBPC collection and transplantation. The catheter exit site was monitored three times a week, and lumen patency was assessed using clinical and radiologic techniques. Catheters were removed prematurely for persistent thrombus, positive blood cultures despite appropriate antibiotics, or mechanical dysfunction. There were no intra-operative or immediate post-operative complications relating to insertion. Thirty-two patients experienced catheter occlusion necessitating urokinase instillation. Persistent occlusive problems were noted in 16 patients, and in 10 patients the catheter had to be removed. Two exit site infections and 17 bacteremias occurred. Catheters had to be removed for persistent infection in two subjects and for mechanical problems in five others. Cost analysis comparing the hybrid catheters alone vs conventional devices revealed a charge of $4230 in patients with hybrid catheters vs. $7530 in those requiring a temporary non-Silastic dialysis catheter in addition to a flexible, long-term Silastic catheter. Hybrid, Silastic, dual-lumen, large-bore central venous catheters are safe, cost-effective and convenient multi-purpose venous access devices that may be used in the setting of autologous PBPC collection and transplantation. The rate of thrombotic, infectious and mechanical complications appears comparable to other central venous access devices.
