A consistent and reproducible depletion technique is crucial for the successful transplantation of an ex vivo depleted graft. Our aim was to evaluate the efficacy of an ex vivo technique for depletion of αβ+ T cells using a biotinylated anti-TCRαβ monoclonal antibody, which was performed by one clinical nurse specialist. Between 2012 and 2017, 119 depletion procedures from 216 apheresis using the anti-TCRαβ monoclonal antibody were performed on 105 pediatric patients. The median log depletion of αβ+ T cells was 4...

BACKGROUND: Elderly ulcerative colitis (UC) is increasing. Elderly UC differ from younger UC with respect to the course of their disease. Granulocyte adsorption apheresis (CAP) is often used to treat elderly UC. We retrospectively analyzed the cases of elderly UC who underwent CAP for remission induction therapy in a comparison with younger UC. METHODS: 96 patients with UC underwent CAP. Patients who concurrently received tacrolimus, biological agents, or high-dose steroid therapy were excluded...

A 49 years old woman (weight 68 kg, BMI 27.3 kg/m2 ) with heterozygous familial hypercholesterolemia (HeFH) and multiple statin intolerance with muscle aches and creatine kinase elevation, presented at the Outpatient Lipid Clinic of Verona University Hospital in May 2015. Hypercholesterolemia was firstly diagnosed during adolescence, followed in adulthood by a diagnosis of Cogan's syndrome, a rheumatologic disorder characterized by corneal and inner ear inflammation. No xanthomas, corneal arcus, or vascular bruits were detectable at physical examination...

In December 2017, 79 delegates attended the 2nd regional plasmapheresis conference and workshop for Southeast Asia (SEA) on the immunomodulatory role of plasma exchange in central and peripheral nervous system disorders in Kuala Lumpur, Malaysia. This meeting featured 6 plenary lectures, interactive sessions dedicated for experience sharing, case presentations, and a practical session for paramedics. Clinical experts and researchers from 7 SEA countries and India shared experience and challenges in treating autoimmune neurological disorders...

PURPOSE: We evaluated the Optia® continuous mononuclear collection (CMNC) system for hematopoietic progenitor cell-apheresis (HPC-A) collection (Terumo BCT, Lakewood, CO) compared to the COBE® Spectra (Terumo BCT, Lakewood, CO), including both large volume leukapheresis (LVL) and non-LVL collections. METHODS: We performed a retrospective data analysis of all autologous HPC-A collections with the Optia® CMNC system (n = 93; LVL = 59, non-LVL = 34) since implementation at our institution and compared it with a similar number of concurrent collections utilizing the COBE® Spectra (n = 96; LVL = 68, non-LVL = 28)...

This article is based on a question of a colleague from North America how coagulation could be triggered between a donor's arm and a fistula needle during plasma donation (synonymous with donor plasmapheresis). The technique of venipuncture and citrate anticoagulation are described. Uncommon and rare problems such as prolonged bleeding, scarring, and thrombosis in plasma donors are discussed. If venous puncture and citrate: blood flow ratio at 1:16 are correctly performed, however, there will be no anticoagulation abnormalities due to plasma donation...

Stimulated by the scientific progress in deciphering the principal elements contributing to the clinical efficacy of extracorporeal photochemotherapy (ECP), the American Council on ECP (ACE) was formed, under the auspices of the American Society for Apheresis (ASFA), to develop a field-guiding Consensus Report. ACE is composed of thirty nationally recognized ECP experts, clinically spanning cancer, transplantation, and autoimmunity and scientifically bridging immunology, bioengineering, and hematology. The two-day meeting took place in Manhattan, April 13-14, 2017, and unanimous consensus on nine pivotal points is herein reported...

Acute thrombotic thrombocytopenic purpura (TTP) is an aggressive thrombotic microangiopathy that if not treated, can have a 90% mortality rate. Clinical manifestations of this disease include profound thrombocytopenia, hemolytic anemia, and end-organ dysfunction. Neurologic symptoms can occur in 80% of patients and range from mild confusion to coma (Scully et al., Br J Haematol 142:819-826). Here, we present the clinical course of a patient diagnosed with new onset acquired TTP who presented with neurologic changes that waxed and waned during her disease course...

Galectin-3 (Gal-3), a β-galactoside-binding lectin that is expressed in mammalian cells, is known to modulate several biological functions such as cell-cell adhesion, macrophage activation, angiogenesis, metastasis, and fibrosis. The goal of this study was to evaluate the ability of Gal-3 depletion apheresis using an adsorption column with immobilized anti-Gal-3-antibody to reduce inflammation induced by Complete Freund's Adjuvant injection in a skin inflammation porcine model. Here, we report that plasma perfusion by apheresis through a Gal-3 binding immuno-affinity column reduces plasma Gal-3 levels to below limits of quantitative detection, and results in significant decrease in skin inflammation, including degree and duration of inflammatory lesions...

Success of peripheral blood stem cell (PBSC) collections depends on patient biological parameters and stable apheresis device performance. We investigated product quality and factors influencing main apheresis procedure outcomes including CD34+ collection efficiency (CE), product volume or platelet CE. We also assessed different CD34+ cell yield prediction algorithms. Autologous PBSC collections by Spectra Optia from myeloma and lymphoma patients were analyzed. Complete blood count (CBC) from patient preprocedure and from collected products were assessed...

BACKGROUND: Therapeutic plasma exchange (TPE) is an extracorporeal procedure which consists of removing the patient's plasma and replacing it with an appropriate replacement fluid. Plasma and blood cells are separated by a centrifugation process. Our department has used TPE for several years, and in 2013 we introduced an institutional apheresis protocol. The main objective of this report is to describe the TPE procedures performed between 2013 and 2016 in the Peruvian population. METHODS: We analyzed the technical and clinical aspects of 864 centrifugal TPE procedures as well as the associated complications...

INTRODUCTION: Limited data are available describing indications for and outcomes of therapeutic plasma exchange (TPE) in cardiac transplantation. METHODS: In a retrospective study of patients who underwent cardiac transplantation at Duke University Medical Center from 2010 to 2014, we reviewed 3 TPE treatment patterns: a Single TPE procedure within 24 h of transplant; Multiple TPE procedures initiated within 24 h of transplant; and 1 or more TPE procedures beginning >24 h post-transplant...

Cytapheresis (removal of cellular blood components) has been employed for treatment of infectious diseases since the 1960s. Techniques have included thrombocytapheresis (buffy coat apheresis) for loiasis, erythrocytapheresis for malaria and babesiosis, and leukocytapheresis for pertussis-associated lymphocytosis. Published data on these applications is largely limited to case level data and small observational studies; as such, recommendations for or against the use of cytapheresis in the treatment of infections have been extrapolated from these limited (and at times flawed) data sets...

BACKGROUND: An increasing demand for human lymphocytes require an efficient, reliable and reproducible lymphocyte process. Here, we compare the Spectra Optia® CMNC protocol with the Optia MNC platform in unmobilised donor lymphocyte collections. PURPOSE: To establish and compare the feasibility, efficiency, and practicability of the two apheresis protocols. METHODS: Data was collected prospectively from 60 non-cytokine stimulate donors who underwent a total of 64 T-cell collection procedures...

This report describes a patient with light chain myeloma and acute renal injury. Serum kappa free light chain (FLC) was extremely elevated, >33,000 mg/dL. Treatment with therapeutic plasma exchange (TPE) started day 2 for biopsy-confirmed cast nephropathy. Bortezomib-containing chemotherapy was initiated on day 5, and hemodialysis for tumor lysis syndrome on day 7. TPE alone decreased kappa FLC >70% by day 5, indicating direct FLC removal was successful in this patient. A total of 25 TPE procedures were performed in a 31-day hospitalization...
