Sedimentation of Apheresis Granulocyte components removes red blood cells. It is used to increase the blood donor pool when blood group-compatible donors cannot be recruited for a patient because of a major ABO incompatibility or incompatible red blood cell antibodies in the recipient. Because granulocytes have little ABO and few other red blood cell antigens on their membrane, such incompatibility lies mostly with the contaminating red blood cells. Video Clip S1 shows the process of red blood cell sedimentation of an Apheresis Granulocyte component...

BACKGROUND AND OBJECTIVES: The Spectra Optia(®) continuous mononuclear cell (CMNC apheresis) system has emerged as the preferred device in peripheral blood stem cell collections over the original two-step Spectra Optia(®) mononuclear cell (MNC apheresis) system. Until now, no comparative data were available for non-stimulated MNC collections that are required for immunotherapy. MATERIALS AND METHODS: We compared collection parameters and product composition for Spectra Optia MNC- as well as CMNC-apheresis systems in non-stimulated MNC collections from 35 registry donors intended for donor lymphocyte infusions...

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) has been considered as a valuable approach in treatment of numerous malignant and none malignant hematologic disorders. However, relapse and poor graft function (PGF) after allo-SCT remain to be controversial issues which may affect the transplantation outcome. Relevant articles were searched in MEDLINE database (2000-2016) using keywords and phrases: donor lymphocyte infusions, allogeneic stem cells transplantation, relapsed hematologic malignancies, booster schedules, cell dose, laboratory monitoring protocols and technical aspects of apheresis...

INTRODUCTION: Thrombocytapheresis is an alternative treatment beneficial in rare circumstances, when cytoreductive agents are contraindicated, drug therapy gave no response or the expected response would be too slow. Here we present a case of a pregnant woman who underwent 5 thrombocytaphereses using Spectra Optia device to reduce circulating platelets (PLT) count and prepare for Cesarian section. PATIENT CHARACTERISTICS AND PERFORMED TREATMENT: A 39-year-old woman with diagnosed chronic myeloid leukemia (CML) was treated with interferon because of too high PLT count...

The World Marrow Donor Organization recommends original granulocyte-colony stimulating factor (G-CSF) for the mobilization of stem cells in healthy unrelated hematopoietic stem cell donors. We report the comparison of a biosimilar G-CSF (Zarzio) with two original G-CSFs (filgrastim and lenograstim) in mobilization in unrelated donors. We included data of 313 consecutive donors who were mobilized during the period from October 2014 to March 2016 at the Medical University of Warsaw. The primary endpoints of this study were the efficiency of CD34+ cell mobilization to the circulation and results of the first apheresis...

BACKGROUND AND OBJECTIVES: Monocytes can be cultured into dendritic cells with addition of autologous plasma, which is highly prone to platelet contamination due to the apheresis process. Since platelets affect the maturation process of monocytes into dendritic cells and might even lead to a diminished harvest of dendritic cells, it is very important to reduce the platelet contamination. A new collection device (Spectra Optia) was analyzed, compared to two established devices (COM.TEC, Cobe Spectra) and evaluated regarding the potential generation of source plasma...

BACKGROUND: Red blood cell (RBC) depletion is a standard graft manipulation technique for ABO-incompatible bone marrow (BM) transplants. The BM processing module for Spectra Optia, "BMC", was previously introduced. We here report the largest series to date of routine quality data after performing 50 clinical-scale RBC-depletions. METHODS: Fifty successive RBC-depletions from autologous (n = 5) and allogeneic (n = 45) BM transplants were performed with the Spectra Optia BMC apheresis suite...

Autologous hematopoietic stem cell transplantation (Auto- HSCT) improves survival in multiple myeloma (MM) and Non-Hodgkin lymphoma (NHL). Traditionally, filgrastim (Neupogen® - recombinant G-CSF) has been used in as a single agent or in combination with plerixafor for stem cell mobilization for auto-HSCT. In Europe, recombinant G-CSF biosimilar (Tevagrastim®) is approved for various indications similar to reference filgrastim, including stem cell mobilization for auto-HSCT; However, tbo- Filgrastim (Granix®) is registered under original biologic application and is not approved for stem cell mobilization in the USA...

BACKGROUND/AIMS: In patients with active ulcerative colitis (UC), pharmacologics, although initially effective in most patients, are associated with refractoriness, loss of response or unfavourable side effects as additional morbidity factors. Depletion of myeloid lineage leucocytes like the CD14(+)CD16(+) monocyte phenotype, which is a major source of tumour necrosis factor-α, by granulocyte/monocyte apheresis (GMA) if effective, is also known to be free from side effects. METHODS: In clinical practice setting, 77 consecutive patients with moderate to severe UC, who failed to respond to first-line medications received GMA with the Adacolumn as remission induction therapy...

BACKGROUND: Intractable pruritus of cholestasis leads to significant morbidity. Therapeutic plasma exchange (TPE) has been shown to be an effective alternative in the setting of refractory pruritus associated with cholestatic liver disease based on several individual reports. Due to rarity of this approach to intractable pruritus, the literature is sparse and therefore TPE, as a treatment for refractory pruritus is currently not in the apheresis guidelines. We present three additional patients with severe intractable pruritus of cholestasis successfully treated with plasma exchange to add to the mounting literature showing this as an effective and safe adjunctive therapy...

Desensitization strategies to safely perform ABO incompatible living donor kidney transplantations are various and still evolving. Given the successful outcome of the majority of the approaches, the current trend is focused on a minimization of treatments. Based on this consideration, the evolution at a single Center of the desensitization protocol is herein described. Starting from 2010, 58 AB0 incompatible living donor kidney transplantations were performed at the University-Hospital of Padua. Over the years, the initial desensitization strategy with rituximab single-dose induction, pre-and post-transplant plasmapheresis and CMV-specific immunoglobulin administration has been shifted to a minimized approach, omitting post-transplant antibody removal in 25 cases...

Psoriatic arthritis (PsA), a chronic inflammatory arthropathy associated with psoriasis, is an intractable immune disorder and refractory to pharmacological intervention. We assessed efficacy of selective depletion of myeloid lineage leukocytes in patients with PsA in a multicenter setting. A total of 20 patients with moderate to severe PsA refractory to conventional and biological disease-modifying antirheumatic drugs were included. Eligible patients had 3 points or more in the classification criteria for PsA...

BACKGROUND: Dysphagia screening is oftentimes a focus of hospitalized patients, but dysphagia can also occur in outpatient settings. Dysphagia can be overlooked by nurses and clinicians, and it is therefore important to educate nurses on the importance of dysphagia screenings. METHODS: This was a randomized prospective pilot study to compare the effect of experiential learning versus traditional PowerPoint learning regarding nurses' attitudes towards performing dysphagia screening in an outpatient setting...

Albert Ebidia
Many articles in today's medical journals, including this very publication, support their findings by providing data collected during the research of their selected study. Various terms used include a randomized group of patients, outcome data, total counts and averages. Many of these terms are then supported by figures and tables depicted by line graphs, bar graphs and histograms. The question to answer is how was all this data gathered? The following discussion will attempt to explain, in simple terms, how the data entry and collection was implemented for the Canadian Apheresis Registry database...

BACKGROUND: The PLASMIC score was recently described as a convenient tool for predicting ADAMTS13 activity ≤10% in patients with possible thrombotic thrombocytopenic purpura (TTP), while awaiting the results of this send-out test. The purpose of this study was to validate the PLASMIC score at our University Medical Center. METHODS: Apheresis records were reviewed from 2008 to 2017 to identify patients who received plasma exchange (PLEX) for suspected TTP. The ADAMTS13 activity and PLASMIC scoring criteria were recorded, and the PLASMIC score was calculated...

Valvular heart disease frequently occurs as a consequence of premature atherosclerosis in individuals with familial hypercholesterolemia (FH). Studies have primarily focused on aortic valve calcification in heterozygous FH, but there is paucity of data on the incidence of valvular disease in homozygous FH. We performed echocardiographic studies in 33 relatively young patients (mean age: 26 years) with homozygous FH (mean LDL of 447 mg/dL, 73% on LDL apheresis) to look for subclinical valvulopathy. Twenty-one patients had evidence of valvulopathy of the aortic or mitral valves, while seven subjects showed notable mitral regurgitation...

REVIEW
Mattia Parolin, Enrico Vidal
In the setting of kidney transplantation, therapeutic apheresis (TA) is employed both for pre-intervention procedures and during the post-transplant period. In pediatric nephrology units, TA is usually performed as a therapeutic plasma exchange (TPE) with dialysis equipment, and using non-plasma replacement fluids. In children undergoing kidney transplantation, complications of TPE are mainly related to its depletive properties combined with the iatrogenic immunodeficiency status of the patient. Moreover, the use of small central venous catheters and the equipment standardized for adults can increase the risk of adverse events...

To harvest for T cell therapy, a 1.6-fold higher number of CD3(+) T cells was collected with MNC mode (N = 10) compared with Auto PBSC mode (N = 5) in COBE Spectra cell separator, but the blood product volume was increased by 3.5-fold. For therapeutic angiogenesis therapy, apheresis was initially performed using Auto PBSC mode (N = 4) to fine tune the blood product volume to omit cell concentration, but the collected number of mononuclear cells was lower than expected. However, an increase of the harvest cycle number from 3...

Macrophage activation syndrome (MAS) is a life-threating complication of systemic juvenile idiopathic arthritis (s-JIA). Steroid and cyclosporine (CsA) are effective for MAS, but, treatment for steroid- and CsA-resistant patients is still challenging. We report the case of steroid and CsA resistant s-JIA associated MAS misdiagnosed as Kawasaki disease (KD), who was successfully treated with the combination of plasma exchange (PE) and leukocytapheresis (LCAP) followed by plasma diafiltration (PDF). PE + LCAP effectively removed proinflammatory cytokines and reduced the number of peripheral white blood cells...
