INTRODUCTION: Therapeutic apheresis (TA) is used inconsistently in pediatric populations. We seek to define our multidisciplinary institutional practice. METHODS: We conducted a retrospective chart review of patients receiving TA from January 1, 2012 through October 31, 2015. Data collected included demographics, American Society of Apheresis (ASFA) indication, complications, and mortality. RESULTS: Over 46 months, 1198 TA procedures were conducted on 289 patients ranging in age from 5 months to 21 years with weights ranging from 4...

BACKGROUND: Peripheral blood progenitor cell (PBPC) mobilization with chemotherapy in addition to Granulocyte-Colony Stimulating Factor (G-CSF) improves cell collection compared to G-CSF alone; however, it is associated with increased risk of neutropenic fever (NF). METHODS: We analyzed risk factors for post-priming NF and NF association with autologous stem cell transplant outcomes. Between 1998 and 2008, 593 adult patients with lymphoma underwent PBPC mobilization with etoposide and G-CSF...

Increasing survival of patients with sickle cell anemia (SCA) well into adulthood results in a rising likelihood of developing hematological malignancy. High-dose chemotherapy with autologous hematopoietic progenitor cell (HPC) rescue is standard of care for several hematological malignancies, but the risk of severe or life-threatening vaso-occlusive phenomena during filgrastim mobilization of HPC for collection poses a potential barrier to this approach. We report the use of automated red cell exchange in preparation for filgrastim mobilization in a patient with homozygous SCA...

OBJECTIVE: Familial hypercholesterolemia (FH) is a genetic disease with very high levels of circulating low density lipoprotein cholesterol (LDL-C) levels that leads to accelerated atherosclerosis. Lipoprotein apheresis is an effective treatment option for patients with FH and results in reduced cardiovascular morbidity and mortality. Circulating progenitor cells (CPCs) are markers of overall vascular health and diminished levels have been associated with decreased reparative potential and worse outcomes...

INTRODUCTION: Membranous nephropathy (MN) is among the most common causes of nephrotic syndrome in adults worldwide. Most patients have primary MN (PMN), an autoimmune condition associated with the IgG anti-PLA2 R autoantibody. For patients with severe disease, standard of care continues to be a 6-month regime of rotating high dose steroids and immunosuppression that comes with a significant side-effect profile. Immunoadsorption is a relatively safe procedure for the extracorporeal removal of specific immunoglobulins without the need for medications...

PURPOSE: Hydroxyethyl starch (HES) and albumin are used as replacement fluids during therapeutic plasma exchange (TPE). HES solutions are no longer recommended in critically ill patients due to its effect on kidneys and coagulation. In this retrospective study, we tried to look at the association between cumulative HES administration and kidney function in patients undergoing TPE. METHODS: Transfusion medicine department register was scrutinized to identify adult patients who had completed at least 5 cycles of TPE during the period June 2014-May 2015...

We surveyed multiple apheresis centers represented by the authors for their clinical approach to the management of anticoagulation issues during therapeutic plasma exchange (TPE). We present the results of their practices and a review of the pertinent literature. As plasma is removed during TPE, replacement with all or partial non-plasma-containing fluids (eg, 5% albumin) may lead to significant changes in hemostasis. These changes are amplified in patients who are receiving anticoagulation. We discuss various anticoagulants as well as the monitoring and adjustment of anticoagulation before, during, and after TPE...

Accumulation of bile acids can lead to invalidating pruritus in cholestatic patients. Few reports exist on the influence of lipoprotein-apheresis (LA) on plasma level of total bile acids (tBA). We report of significant decrease in tBA levels and drastic improvement of pruritus in a 5-year-old girl with arthrogryposis-renal failure-cholestasis syndrome. We present LA as a suitable rescue treatment option in therapy-refractory cholestasis-associated pruritus, at least as bridge until a long-term solution such as entero-biliary anastomosis or transplantation is possible...

PURPOSE: The objective of this retrospective analysis was to present our single-center experience with intravenous (IV) calcium replacement and regional citrate anticoagulation in pediatric apheresis therapy with the aim of developing a standard operating procedure to minimize symptomatic hypocalcemia. METHODS: We analyzed apheresis procedures in patients <18 years of age over a 2-year time period (Jan 2012 to Dec 2014). Procedures in tandem with other extracorporeal therapies, including continuous renal replacement therapy, extracorporeal liver support, and extracorporeal membrane oxygenation, were excluded...

Congenital factor XI (FXI) deficiency is associated with a variable bleeding phenotype. Recent reports have documented the use of therapeutic plasma exchange to rapidly and isovolumetrically increase FXI levels before invasive procedures in patients with congenital FXI deficiency. We report a case of acquired FXI deficiency in a pregnant woman with lupus. We proved that the inhibitor was an IgG, therefore potentially capable of crossing the placenta. While immune suppression eliminated detectable circulating inhibitor, the woman's FXI remained quite low...

REVIEW
Ugur Sahin, Taner Demirer
Multiple myeloma (MM) is the leading indication of autologous hematopoietic stem cell transplantation (AHSCT) worldwide. The collection of PBSCs is the essential step for AHSCT. The limits for minimum and optimum CD34(+) cells collected have been accepted as 2 × 10(6) /kg and ≥4 × 10(6) /kg for single AHSCT; 4 × 10(6) /kg and ≥8-10 × 10(6) /kg for double AHSCT. Despite the success of conventional methods for PBSC mobilization in MM, mobilization failure is still a concern depending on patient age, duration of disease, and the type of induction therapy...

In the implementation of American Society for Apheresis national guidelines, the decision for therapeutic plasma exchange may be confounded by a clinical presentation that fits both a Category I and IV designation. We report the case of a 45-year-old female who presented with concern for a Category IV disorder, gemcitabine-induced thrombotic microangiopathy, and was ultimately diagnosed with a Category I disorder, idiopathic thrombotic thrombocytopenic purpura. This case highlights the importance of ruling out idiopathic TTP by a thorough evaluation for ADAMTS13 activity and inhibitor, even when an alternate thrombotic microangiopathy diagnosis may be likely...

PURPOSE: Terumo BCT Spectra Optia (O) and Fenwal Amicus (A) can perform therapeutic plasma exchange (TPE). We compared these systems in a prospective, randomized, crossover study of 81 paired procedures. Primary objective was to determine if there was a difference in platelet loss between the instruments. Secondary objectives were to determine differences in procedure time (PT), plasma removal efficiency (PRE 1), plasma removal rate (PRR), and fluid balance (FB). METHODS: Fifty-seven adults undergoing 162 procedures were included...

BACKGROUND: Acute myeloid leukemia (AML) is a malignancy characterized by rapid clonal proliferation of myeloid precursors, which can result in hyperleukocytosis. Leukapheresis can be used to rapidly reduce the white blood cell count (WBC). However, the only FDA cleared device for WBC depletion, the COBE Spectra, will no longer be supported by the manufacturer in 2017, and there are few studies comparing different methods of leukapheresis. CASE REPORT: A 68-year-old African American female was admitted to the hospital for relapse of her AML...

Severe falciparum malaria is associated with multiple organ dysfunction and a high rate of fatal outcome. Malaria is a world-wide disease in tropical areas through the bites of vector mosquitoes. Parasitic protozoans introduced by the mosquito's saliva to the blood travel to the liver then mature and reproduce. In humans, malaria is caused by Plasmodium falciparum, P. malariae, P. ovale, P. vivax, and P. knowlesi, and P. falciparum causes most deaths. Typical malaria symptoms include fever, chills, fatigue, headache, nausea, and vomiting...

INTRODUCTION: High-dose chemotherapy with autologous hematopoietic stem cell transplantation (auto-HSCT) improves the outcome of patients with multiple myeloma (MM). It seems that auto-HSCT is also a feasible therapeutic option in MM dialysis-dependent (MMDD) patients. However, to perform transplantation, a sufficient number of stem cells must be collected. MATERIALS AND METHODS: Given that data on mobilization of auto-HSC efficacy and safety in dialysis-dependent patients are limited, we report data from all Polish Centers belonging to the Polish Multiple Myeloma Group...

BACKGROUND: The demand for therapeutic plasma-derived products poses a challenge to blood collection agencies (BCAs). In 2014-2015, the volume of plasma sent for fractionation met 17.7% of Quebec's needs for immunoglobulins. This article aims to offer an exploration of the paths blood donors follow in order to become plasma and platelet donors (PPDs). STUDY DESIGN AND METHOD: This analysis is based on semi-structured interviews with 50 PPDs in Quebec, Canada. Our analysis focused on the occurrence of events and the presence of contextual elements identified through: (1) factual data on PPDs; and (2) what PPDs identified as being an influence on their donation experience...
