BACKGROUND: Pure red cell aplasia (PRCA) is a well-documented potential side effect of ABO major mismatched allogeneic hematopoietic stem cell transplants. This side effect may be self-limiting, but is sometimes treated using modalities such as steroids, antithymocyte globulin, donor lymphocyte infusions, rituximab, or plasma exchanges. Another well-documented cause of pure red cell aplasia is a chronic parvovirus B19 infection, which may be seen in immunocompromised hosts. The treatment of this cause of PRCA includes removal of immunosuppression, intravenous immunoglobulin (IVIg), or rituximab; however, this condition may also be self-limiting...

INTRODUCTION: Physicians from diverse training backgrounds practice apheresis medicine. Pathology residents' exposure to apheresis may vary depending on which department performs these procedures. Milestones for Apheresis education were published in 2012, but the degree of utilization in residency curriculum development is unknown. This study describes the current state of apheresis education for pathology residents. METHODS: We sent a 15 question electronic survey to 141 pathology programs identified through the American Medical Association Residency and Fellowship Database...

BACKGROUND: Chronic inflammatory demyelinating polyneuropathy (CIDP) is a rare paralyzing inflammatory neuropathy with probably autoimmune origin. While plasma exchange (PE) constitutes a first-line treatment option for CIDP, there is only little known about the efficacy and safety of immunoadsorption (IA), a more selective apheresis procedure with assumed better tolerability. METHODS: In this prospective-randomized pilot trial, patients were randomly assigned to receive 6 sessions of PE (n = 10) or IA (n = 10) treating equal plasma volumes...

BACKGROUND: Therapeutic plasma exchange (TPE) has evolved to an accepted therapy for selected indications. However, it is technically challenging in children. Moreover, data on safety and efficacy are mainly derived from adult series. The aim of this study was to review the procedure in the context of clinical indications, effectiveness, and safety. STUDY DESIGN AND METHODS: All TPE procedures performed at a tertiary care hospital during a 12-year period (2005-2016) were retrospectively evaluated...

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...

Autologous hematopoietic progenitor cell (HPC) transplant through peripheral blood mobilization and leukapheresis is a standard treatment for many patients with hematopoietic malignancies. Although leukapheresis is usually completed with no complications, we present a case in which the hematopoietic progenitor cells clotted during collection. The patient had no history of hypercoagulopathy. It was identified that the anticoagulant infusion line was partially constricted by a blood warmer clamp. The machine did not alarm...

BACKGROUND: Administration of an anticoagulant during therapeutic plasma exchange (TPE) is necessary to avoid circuit clotting and impaired treatment effectiveness. Citrate is the preferred anticoagulant for apheresis worldwide, and unfractionated heparin (UH) is the second most preferred, yet there are only a few published studies regarding the use of UH during TPE. There are even fewer studies regarding the use of low-molecular-weight heparin (LMWH) and TPE performed without anticoagulation...

Despite controversy regarding the use of granulocyte/monocyte adsorption (GMA) in inflammatory bowel disease, some studies have shown favorable outcomes when it is used in steroid-dependent patients with ulcerative colitis (UC). The mechanisms responsible for such outcomes are not well characterized, but changes in immune cell populations and cytokine levels have been suggested to play an important role. We report the cases of 3 patients with chronically active severe UC who underwent GMA due to an inadequate response to standard and rescue therapy, as well as changes to their plasma cytokine profile...

Granulocyte-colony stimulating factor (G-CSF) mobilizes and increases the amount of hematopoietic stem cells in peripheral blood, enabling its harvest by few apheresis procedures. The pegylated G-CSF has longer half-life and is given once only, which is more comfortable for patients, whereas the non-pegylated requires multiple daily injection because of its short half-life. We summarized results of randomized trials comparing the efficacy and safety of pegylated and non-pegylated G-CSF for peripheral blood stem cell mobilization...

BACKGROUND: Atypical hemolytic uremic syndrome (aHUS) is a rare disease characterized by thrombocytopenia, microangiopathic hemolytic anemia, and acute kidney failure. The disease is difficult to diagnose due to its similarity with other hematologic disorders, such as thrombotic thrombocytopenic purpura (TTP). However, genetic mutations are found in 50-70% of patients with aHUS and can be useful in its diagnosis. STUDY DESIGN AND METHODS: A 40-year-old male presented to our hospital with acute kidney injury, evidenced by high creatinine levels (8...

Plerixafor (Mozobil) in combination with granulocyte colony-stimulating factor (G-CSF) has shown to increase mobilization of peripheral blood stem cells (PBSC) as compared to G-CSF alone in patients undergoing autologous stem cell transplantation (ASCT). However, up to 25% of patients treated with G-CSF alone still fail mobilization. Adding plerixafor to poor mobilizers allows to rescue these patients from mobilization failure and to reduce the number of apheresis sessions. The goal of this retrospective study was to capture the impact of plerixafor on treatment outcome and on apheresis department efficiency...

Treatment of primary focal segmental glomerulosclerosis (FSGS) and its recurrence after kidney transplantation associated with rapid deterioration of kidney function remains to be challenging despite advances in immunosuppressive therapy. The presence of circulating factors has been postulated to be a pivotal player in the pathogenesis of FSGS, although suPAR and CLCF-1 have been identified as the most promising causative factors. The potential therapeutic effect of suPAR elimination in an FSGS patient using CytoSorb, a hemoadsorption device that gained attention in the cytokine elimination in septic patients, was studied...

Thyroid storm or severe thyrotoxicosis results from extreme thyroid hormone elevation. Therapy includes medical management to prevent hormone production, release, recycling, and peripheral conversion while stabilizing adrenergic tone. Thyroid dysfunction is the usual cause but it can be due to excessive thyroid hormone ingestion. Therapeutic plasma exchange (TPE) has been used to rapidly remove protein-bound thyroid hormone. American Society for Apheresis guidelines make a weak recommendation to perform TPE in selected patients in the treatment of thyrotoxicosis based on low quality evidence...

BACKGROUND: Apheresis treatments can be performed with peripheral venous catheters (PVC), although central venous catheters (CVC) are inserted when PVCs fail or patient with history of difficult vascular access prior to the apheresis. Ultrasound guidance for PVC has shown promising results in other settings. PURPOSE: To investigate if ultrasound guidance for PVC could be implemented among apheresis nurses. Second, how implementation of ultrasound guidance affected the number of CVCs used for apheresis per patient...

In adults, extracorporeal photopheresis (ECP) is widely utilized for a variety of indications, most commonly cutaneous T-cell lymphoma, acute or chronic graft-versus-host disease (GVHD), solid organ transplant rejection, and other autoimmune and T-cell-mediated disorders. In pediatric patients, the majority of case series and reports have focused on its use in the management of acute and chronic GVHD. Currently utilized ECP technologies were designed for adult patients and there are several challenges in adapting these technologies for use in children...

BACKGROUND: Factor XI (FXI) deficiency (hemophilia C [HEM-C]) is a bleeding disorder with unpredictable severity that correlates poorly with FXI coagulation activity (FXI:C). It poses a perioperative hemostatic management challenge. For US patients with severe disease, fresh frozen plasma (FFP) or, in current use, thawed plasma is the most readily available option but comes with risk of volume overload. We report our experience of using therapeutic plasma exchange (TPE) as an alternative perioperative management strategy...
