Separation of one or more kinds of cells from whole blood with the return of other blood cell constituents to the patient or donor. This is accomplished with an instrument that uses centrifugation to separate the cells into different layers based on the differences in cell density (displacement) or drag coefficients in a current (elutriation). The procedure is commonly used in adoptive transfer to isolate NK cells, lymphocytes, or monocytes.

Infection of apheresis cells by parvovirus B19. (1/271)

Parvovirus B19 is the only member of the Parvoviridae family known to cause disease in humans. Owing to the high level of cell tropism the virus can only replicate in proliferating and differentiating erythroid precursor cells, which are present in human bone marrow and foetal liver. As human bone marrow is very difficult to obtain, an alternative in vitro system for the propagation of B19 virus has been developed, based on the application of mobilized haemapoietic progenitor (apheresis) cells. These cells are routinely harvested from cancer patients after treatment with recombinant human granulocyte/macrophage colony-stimulating factor. Replication of parvovirus B19 in vitro is possible in these cells after stimulation with erythropoietin. Therefore, this system is an easily, accessible alternative to the use of human bone marrow in parvovirus B19 infection assays.  (+info)

CD34+ cell enumeration in peripheral blood and apheresis samples, using two laboratory diagnostic kits or an institutional protocol. (2/271)

In order to prepare the substitution of a commercially available diagnostic kit, ProCOUNT (Becton Dickinson) or Stem-Kit (Coulter Immunotech), for our institutional protocol, we compared the three techniques for the numeration of CD34+ progenitor cells in 50 peripheral blood and 51 apheresis samples, obtained from cancer patients or healthy donors. We show here that the three techniques yield results of the same order of magnitude. Although statistical analyses demonstrate significant differences between the three methods, these differences turned out to be clinically insignificant in most situations. Observed differences mostly affect samples with the highest content of CD34+ cells, while the three assays provide equivalent results for values that are close to clinically relevant thresholds (20 x 10(3) CD34+ cells/ml in peripheral blood to start apheresis, and accumulated number above 3 x 10(6) CD34+ cells/kg to stop apheresis). This study also supports the view that institutional protocols can provide a highly reliable determination of CD34+ cells counts and percentages. However, because institutional protocols often use research reagents and vary from institution to institution, the use of diagnostic kits may be prefered as one way to improve quality assurance in the practice of cell therapy.  (+info)

Superior autologous blood stem cell mobilization from dose-intensive cyclophosphamide, etoposide, cisplatin plus G-CSF than from less intensive chemotherapy regimens. (3/271)

The study purpose was to determine if G-CSF plus dose-intensive cyclophosphamide 5.25 g/m2, etoposide 1.05 g/m2 and cisplatin 105 mg/m2 (DICEP) results in superior autologous blood stem cell mobilization (BSCM) than less intensive chemotherapy. From January 1993 until May 1997, 152 consecutive patients with non-Hodgkin's lymphoma (n = 55), breast cancer (n = 47), Hodgkin's disease (n = 14), multiple myeloma (n = 9), AML (n = 9), or other cancers (n = 18) initially underwent BSCM by one of three methods: Group 1: G-CSF alone x 4 days (n = 30). Group 2: disease-oriented chemotherapy, dosed to avoid blood transfusions, followed by G-CSF starting day 7 or 8, and apheresis day 13 or 14 (n = 82). Group 3: DICEP days 1-3, G-CSF starting day 14, and apheresis planned day 19, 20 or 21 (n = 40). A multivariate analysis was performed to determine which factors independently predicted BSCM. The median peripheral blood CD34+ (PB CD34+) cell count the morning of apheresis linearly correlated with the number of CD34+ cells removed per litre of apheresis that day. The median PB CD34+ cell count and median CD34+ cells x 10(6) removed per litre of apheresis were highest for Group 3, intermediate for Group 2, and lowest for Group 1. By multivariate analysis, mobilization group (3 > 2 > 1), disease other than AML, no prior melphalan or mitomycin-C, and less than two prior chemotherapy regimens predicted better BSCM. Out of 15 Group 3 patients who had infiltrated marrows, 11 had no detectable cancer in marrow and apheresis products after DICEP. These data suggest that DICEP results in superior BSCM than less intensive chemotherapy regimens.  (+info)

Image-guided central venous catheters for apheresis. (4/271)

Apheresis is an increasingly important procedure in the treatment of a variety of conditions, sometimes performed via peripheral access because of concern over major complications associated with central venous catheter (CVC) placement. This study sought to determine the safety and success for ultrasound and fluoroscopically guided, non-tunneled dual lumen CVCs placed for apheresis. Prospective data collection was made of 200 attempted CVC placements in the radiology department utilizing real time sonographic guidance. The complications relating to placement were noted in all and the number of passes required for venepuncture and whether a single wall puncture was achieved was recorded in 185 cases. Duration of catheterization and reason for line removal were recorded in all. Our study group included 71 donors providing peripheral blood stem cells for allogeneic transplant. CVCs were successfully placed in all patients, 191 lines in the internal jugular and seven in the femoral vein. 86.5% required only a single pass and 80.5% with only anterior wall puncture. Inadvertent but clinically insignificant arterial puncture occurred in six (3%) cases. In no case did this prevent line placement. There were no other procedure-related complications. 173 (87.4%) catheters were removed the same day. No catheters were removed prematurely. There was one case of prolonged venous bleeding. Our study demonstrates the safety of central venous catheters for apheresis provided that duration of catheterization is short and real-time sonographic guidance is used for the puncture, and guide wire and catheter placement are confirmed fluoroscopically.  (+info)

Recombinant human thrombopoietin in combination with granulocyte colony-stimulating factor enhances mobilization of peripheral blood progenitor cells, increases peripheral blood platelet concentration, and accelerates hematopoietic recovery following high-dose chemotherapy. (5/271)

Lineage-specific growth factors mobilize peripheral blood progenitor cells (PBPC) and accelerate hematopoietic recovery after high-dose chemotherapy. Recombinant human thrombopoietin (rhTPO) may further increase the progenitor-cell content and regenerating potential of PBPC products. We evaluated the safety and activity of rhTPO as a PBPC mobilizer in combination with granulocyte colony-stimulating factor (G-CSF) in 29 breast cancer patients treated with high-dose chemotherapy followed by PBPC reinfusion. Initially, patients received escalating single doses of rhTPO intravenously (IV) at 0.6, 1.2, or 2.4 micrograms/kg, on day 1. Subsequent patients received rhTPO 0.6 or 0.3 micrograms/kg on days -3, -1, and 1, or 0.6 micrograms/kg on days -1 and 1. G-CSF, 5 micrograms/kg IV or subcutaneously (SC) twice daily, was started on day 3 and continued through aphereses. Twenty comparable, concurrently and identically treated patients (who were eligible and would have been treated on protocol but for the lack of study opening) mobilized with G-CSF alone served as comparisons. CD34(+) cell yields were substantially higher with the first apheresis following rhTPO and G-CSF versus G-CSF alone: 4.1 x 10(6)/kg (range, 1.3 to 17.6) versus 0.8 x 10(6)/ kg (range, 0.3 to 4.2), P =.0003. The targeted minimum yield of 3 x 10(6) CD34(+) cells/kg was procured following a single apheresis procedure in 61% of the rhTPO and G-CSF-mobilized group versus 10% of G-CSF-mobilized patients (P =.001). In rhTPO and G-CSF mobilized patients, granulocyte (day 8 v 9, P =.0001) and platelet recovery (day 9 v 10, P =.07) were accelerated, and fewer erythrocyte (3 v 4, P =.02) and platelet (4 v 5, P =.02) transfusions were needed compared with G-CSF-mobilized patients. Peripheral blood platelet counts, following rhTPO and G-CSF, were increased by greater than 100% and the platelet content of PBPC products by 60% to 110% on the first and second days of aphereses (P <.0001) with the greatest effect seen with repeated dosing of rhTPO at 0.6 microgram/kg. rhTPO is safe and well tolerated as a mobilizing agent before PBPC collection. Mobilization with rhTPO and G-CSF, in comparison to a comparable, nonrandomized G-CSF-mobilized group of patients, decreases the number of apheresis procedures required, may accelerate hematopoietic recovery, and may reduce the number of transfusions required following high-dose chemotherapy for breast cancer.  (+info)

Potential role for hyaluronan and the hyaluronan receptor RHAMM in mobilization and trafficking of hematopoietic progenitor cells. (6/271)

Although the mechanism(s) underlying mobilization of hematopoietic progenitor cells (HPCs) is unknown, detachment from the bone marrow (BM) microenvironment and motility are likely to play a role. This work analyzes the motile behavior of HPCs and the receptors involved. CD34(+)45(lo/med)Scatterlo/med HPCs from granulocyte colony-stimulating factor (G-CSF)-mobilized blood and mobilized BM were compared with steady-state BM for their ability to bind hyaluronan (HA), their expression of the HA receptors RHAMM and CD44, and their motogenic behavior. Although RHAMM and CD44 are expressed by mobilized blood HPCs, function blocking monoclonal antibodies (MoAbs) identified RHAMM as a major HA binding receptor, with a less consistent participation by CD44. Permeabilization of mobilized blood HPCs showed a pool of intracellular (ic) RHAMM and a smaller pool of icCD44. In contrast, steady-state BM HPCs have significantly larger pools of icRHAMM and icCD44. Also, in contrast to mobilized blood HPCs, for steady-state BM HPCs, MoAbs to RHAMM and CD44 act as agonists to upregulate HA binding. The comparison between mobilized and steady-state BM HPCs suggests that G-CSF mobilization is associated with depletion of intracellular stores of HA receptors and modulates HA receptor usage. To confirm that mobilization alters the HA receptor distribution and usage by HPCs, samples of BM were collected at the peak of G-CSF mobilization in parallel with mobilized blood samples. HA receptor distribution of mobilized BM HPCs was closely matched with mobilized blood HPCs and different from steady-state BM HPCs. Mobilized BM HPCs had lower pools of icHA receptors, similar to those of mobilized blood HPCs. Treatment of mobilized BM HPCs with anti-RHAMM MoAb decreased HA binding, in contrast to steady-state BM HPCs. Thus, G-CSF mobilization may stimulate an autocrine stimulatory loop for HPCs in which HA interacts with basal levels of RHAMM and/or CD44 to stimulate receptor recycling. Consistent with this, treatment of HPCs with azide, nystatin, or cytochalasin B increased HA binding, implicating an energy-dependent process involving lipid rafts and the cytoskeleton. Of the sorted HPCs, 66% were adherent and 27% were motile on fibronectin plus HA. HPC adherence was inhibited by MoAbs to beta1 integrin and CD44, but not to RHAMM, whereas HPC motility was inhibited by MoAb to RHAMM and beta1 integrin, but not to CD44. This finding suggests that RHAMM and CD44 play reciprocal roles in adhesion and motility by HPCs. The G-CSF-associated alterations in RHAMM distribution and the RHAMM-dependent motility of HPCs suggest a potential role for HA and RHAMM in trafficking of HPCs and the possible use of HA as a mobilizing agent in vivo.  (+info)

Autoaggression syndrome resembling acute graft-versus-host disease grade IV after autologous peripheral blood stem cell transplantation for breast cancer. (7/271)

Acute graft-versus-host disease (aGVHD) after autologous progenitor cell transplantation has been associated with blood transfusion or cyclosporine. Mild aGVHD grades I-II, identified as autoaggression or engraftment syndrome, has recently been described in autologous progenitor transplantation. Here, we report the first case of pathologically documented grade IV aGVHD after autologous peripheral blood progenitor cell transplantation in a patient with breast cancer. The allogeneic origin was excluded by molecular techniques, and no cyclosporine or cytokines were administered.  (+info)

Enrichment of peripheral blood CD34+ cells for transplantation using a fully automated immunomagnetic cell selection system and a novel octapeptide releasing agent. (8/271)

Positive selection of CD34+ cells is being increasingly performed to support hematological reconstitution following high-dose and dose-intensive chemotherapy and to reduce the non-target cell content of transplants. The present study was designed to evaluate the performance of an immunomagnetic cell selection system, including comparison of enzyme and peptide releasing agents and of semi-automated and fully automated selection systems. A total of 74 immunomagnetic CD34+ cell selection procedures were performed involving 55 subjects, the majority of whom had hematologic malignancies. Median CD34+ cell purity with a newly developed specific octapeptide releasing agent (98.5%; 81.0-99.0%) was significantly higher (P = 0.002) than that with chymopapain (85.8%; 28.1-99.7%). No significant differences were observed between semi-automated and fully automated systems in CD34+ cell purity or yield or time to WBC or platelet recovery. Immunomagnetic selection was found to provide highly purified populations of CD34+ cells in sufficient numbers for use in transplantation procedures. CD34+ cell transplants supported rapid and reliable hematologic reconstitution. Use of a fully automated system markedly reduced the time and labor required for immunomagnetic selection, potentially affording more standardized and reproducible positive selection of CD34+ cells.  (+info)

To carry out in vitro research procedures on plasma or leukocyte components of whole blood, it is often necessary to obtain larger quantities of plasma or leukocytes than can be safely obtained by simple phlebotomy. These components can be easily and safely obtained using a well-established standard apheresis procedure that is in common use at the National Institutes of Health Apheresis Unit. This protocol describes the implementation of the same apheresis procedure at the National Blood Transfusion Center in Bamako, Mali. This is not a research protocol per se, but rather an adjunct protocol which allows healthy donors 18-55 years of age to undergo apheresis. Subjects must already be enrolled in another protocol which has been approved by the National Institute of Allergy and Infectious Diseases Institutional Review Board and the Faculty of Medicine, Pharmacy, and Odonto-Stomatology Ethics Committee ...

You are not able to breathe fully; you just take little breaths while you are dealing with something like this, said his father, Farrukh Farid, a co-owner of the Wallingford-based company, Edible Arrangements. After searching the Internet for answers, and traveling to hospitals in several states to talk to doctors, he was surprised to find that Dr. Mistry at YNHH had treated nine children in the United Kingdom with the same condition as his son. Two had been treated with transplants, and one of those had later married and had children. Farid considered LDL (low-density lipoprotein) apheresis treatment for his son at Johns Hopkins Medical Center and also visited homeopathic and herbal specialists in Dubai and Southeast Asia, but he believed that a liver transplant was the best solution. The Farids expected to wait at least a year for a liver donation. Farrukh was surprised three months later when the phone rang while he was home playing with his son.. When I got the call, time stood still for ...
LDL apheresis, a potent therapeutic modality that removes cholesterol within several hours, has been reported to increase the skeletal muscle blood flow when repeated for 3 weeks.26 In the present study, we first demonstrated that a single session of LDL apheresis improved acetylcholine-induced endothelium-dependent vasodilatation associated with the reduction in plasma LDL cholesterol. This observation supports the concept that hypercholesterolemia causes endothelial dysfunction and indicates that short-term correction of hypercholesterolemia could restore endothelial function.. Although the precise mechanisms of amelioration of endothelium-dependent vasodilatation by lipid-lowering therapy remain to be elucidated, several possibilities have been suggested: (1) improvement of endothelium-derived relaxing factor (EDRF) production, (2) decrease in the inactivating factors of EDRF, (3) decrease in the endothelium-derived contracting factors, (4) regression of the diffusional barrier for EDRF, (5) ...

The TheraSorb® LDL therapy system consists of two reusable adsorbers, available in different sizes, that remove LDL cholesterol, Lp(a) and VLDL from the patient´s blood. The sepharose volume constituting the adsorbers is 100 mL for the LDL pro adsorber and 200 mL for the LDL adsorber. The plasma volumes processed during an LDL apheresis treatment can be adjusted to the patient´s need. Between the treatments, both adsorbers are stored in a preservation solution and must be kept at 2-8 °C. Up to 20 treatments can be performed with a single pair of either LDL pro or LDL adsorbers for one patient. The treatment is well tolerated due to the low bradykinin release, which otherwise can cause severe hypotension. Furthermore, the low extracorporeal volume of about 180 mL allows for the treatment of patients with a low body weight in double-needle mode. TheraSorb LDL removal is a highly selective procedure. - Suomi

It has been reported that an intensive, two GMA session per week produced a higher remission rate and in a shorter time as compared with one GMA session per week in patients with active UC [24]. In this study, we found that intensive GMA as two sessions per week, up to 10 sessions and weekly GMA, up to 10 sessions were associated with similar remission rates in patients with active CD, but time to remission was significantly better with the former as compared with the latter. The mean time to remission was 5 weeks in the weekly GMA vs 3 weeks in the intensive GMA. The obvious difference between the two treatment frequencies appears to be shortening of morbidity time by intensive GMA.. Dignass et al. compared 5 and 10 GMA apheresis treatments in steroid-refractory or steroid-dependent UC patients, and reported that 5 GMA sessions were not inferior to 10 sessions [26]. In their study protocol, patients received 5 GMA treatments, once a week over 5 consecutive weeks, or 10 treatments, twice weekly ...

Familial hypercholesterolemia is a genetic disorder characterized by high cholesterol levels, specifically very high levels of low-density lipoprotein, in the blood and early cardiovascular disease. Homozygous Familial Hypercholesterolemia (HoFH) is a rare, but very severe form of an inherited disorder resulting from a genetic mutation on chromosome number 19. This mutation makes the liver incapable of metabolizing cholesterol, specifically low-density lipoprotein (LDL), resulting in very high LDL levels. The disorder leads to aggressive atherosclerosis, which if left untreated, causes individuals to experience heart attacks or death before age 30. Many patients with homozygous FH must undergo LDL apheresis on a regular basis. LDL Apheresis is a process by which blood is removed, LDL-C is filtered out, and then the persons blood is returned to their body. It is similar to dialysis. This form of familial hypercholesterolemia occurs in about 1 in 160,000 to one million people worldwide.. ...
Anaphylactoid Reactions: Sudden and potentially life-threatening anaphylactoid reactions have occurred in some patients dialyzed with high-flux membranes treated concomitantly with an ACE inhibitor. In such patients, dialysis must be stopped immediately, and aggressive therapy for anaphylactoid reactions must be initiated. Symptoms have not been relieved by antihistamines in these situations. In these patients, consideration should be given to using a different type of dialysis membrane or a different class of antihypertensive agent. Anaphylactoid reactions have also been reported in patients undergoing low-density lipoprotein apheresis with dextran sulfate absorption and in patients undergoing desensitizing treatment with hymenoptera venom ...
Lipid apheresis effectively lowers LDL-cholesterol even in drug-unresponsive severely hypercholesterolemic patients. This results in improvement of symptoms of coronary artery disease, reduces progression of coronary atherosclerosis, and decreases coronary event rates. Besides aggressive lipid lowering itself, these effects may also be due to nonselective removal of other high molecular weight proteins leading to improved hemorheology. Lipid apheresis is also used for treating symptoms of vascular diseases outside the coronary arteries, such as peripheral arterial disease and the angioneuropathic diabetic foot syndrome. This review discusses putative effects of lipid apheresis and rheophereis on restoring pathophysiological processes involved in the development of symptoms of peripheral arterial disease, critical limb ischemia, and the diabetic foot syndrome. The clinical experience with lipid apheresis and rheopheresis in treating patients with peripheral arterial disease and the diabetic foot syndrome
Low-density lipoprotein (LDL) is the major cholesterol carrying lipoprotein in your blood. LDL apheresis is a procedure that takes blood outside the body to remove the LDL-cholesterol and then returns the plasma and blood back to the body. This procedure is used if diet or lipid-lowering drug therapy has not lowered high LDL-cholesterol levels adequately..

Lipoprotein-apheresis (apheresis) removes LDL-cholesterol in patients with severe dyslipidemia. However, reduction is transient, indicating that the long-term cardiovascular benefits of apheresis may not solely be due to LDL removal. Microparticles (MPs) are submicron vesicles released from the plasma membrane of cells. MPs, particularly platelet-derived MPs, are increasingly being linked to the pathogenesis of many diseases. We aimed to characterize the effect of apheresis on MP size, concentration, cellular origin, and fatty acid concentration in individuals with familial hypercholesterolemia (FH). Plasma and MP samples were collected from 12 individuals with FH undergoing routine apheresis. Tunable resistive pulse sensing (np200) and nanoparticle tracking analysis measured a fall in MP concentration (33 and 15%, respectively; P , 0.05) pre- to post-apheresis. Flow cytometry showed MPs were predominantly annexin V positive and of platelet (CD41) origin both pre- (88.9%) and post-apheresis ...

In the two phase III randomized trials, 298 patients with NHLr and 302 with MMr were recruited. In the NHL group, the primary end point (,5 x 106 CD34+ cells/kg) was reached in 59% of the plerixafor-treated patients and 20% of those who received placebo (P,0.001). In the plerixafor group, 86.7% obtained at least 2 x 106 CD34+ cells/kg, compared to 47.3% in the placebo group, which is considered the minimum requirement to safely proceed to autologous transplant (P,0.001). Results were similar in the MM study, where the primary end point (,6 x 106 CD34+ cells/kg) was reached in 71.6% in the plerixafor group and 34.4% in the placebo group (P,0.001). Comparing between groups for the achievement of at least 2 x 106 CD34+ cells/kg, this was also higher in patients given plerixafor at 95.3% versus 88.3% (P=.031). Fifty-four percent of patients met the primary endpoint after one apheresis following plerixafor, while 56% of patients receiving placebo required four apheresis sessions to reach this ...

In this study, the in vitro and in vivo antitumor properties of the IL-2-activated MNCs from UCBCs in comparison with IL-2-activated MNCs from PBCs were explored. The NK cytotoxicity levels of UCBCs were very low compared with PBCs prior to in vitro activation (data not shown). After IL-2 activation, however, there was significant antitumor cytotoxicity against NK-sensitive/LAK-resistant and LAK-sensitive tumor target cells (Fig. 1)⇓ . Similar results have been observed by other investigators (20, 21, 22, 23, 24, 25, 26) . The activated UCBCs were not only cytotoxic to hematological malignant cells but also considerably cytotoxic to human breast cancer cells (Fig. 2)⇓ . The level of cytotoxicity of activated cord blood cells against breast cancer was not different from that of similarly activated MNCs from peripheral blood apheresis product. This result is different from what we observed with K562 and Raji tumor targets. The precise reason for this difference is not clear at this ...

  • Blood Component Removal" is a descriptor in the National Library of Medicine's controlled vocabulary thesaurus, MeSH (Medical Subject Headings) . (
  • These laboratories are regulated by the United States Food and Drug Administration (FDA) and are inspected and accredited by a professional association such as the American Association of Blood Banks (AABB). (
  • FNHTR are caused not only by leucocyte antigen-antibody reactions but also by the cytokines produced by leucocytes in the transfused blood component. (
  • This would be more effectively prevented if the leucocytes were removed immediately after the blood is collected, avoiding the formation of cytokines. (
  • Leucodepletion of blood components removes ≥ 99% of contaminating leucocytes resulting in a reduction in the leucocyte count to less than 1 x 10 6 per unit. (
  • The blood circulates through a machine that separates it into its components. (
  • A recirculation system is provided so that blood flows at a reduced rate through the processing system during the return cycle in order to minimize return cycle time while maintaining the stable position of the interface between buffy coat and red blood cell layers. (
  • Although there are over 600 known red blood cell antigens organized into 22 blood group systems, routine blood typing is usually concerned with only two systems: the ABO and Rh blood group systems. (
