What's the difference between apheresis and hemapheresis?
Apheresis
Definition:
(n.) The dropping of a letter or syllable from the beginning of a word; e. g., cute for acute.
(n.) An operation by which any part is separated from the rest.
Example Sentences:
(1) Circulating numbers did not fall significantly during apheresis.
(2) Platelet concentrates collected by continuous flow automated apheresis (Fenwal CS-3000) were compared with those collected by manual apheresis to determine whether the prolonged centrifugation and vigorous resuspension affected platelet viability and in vitro function.
(3) Since exposure to blood products occurs on a daily basis during hemapheresis, the acquired immunodeficiency syndrome (AIDS) epidemic has a serious impact both for patients undergoing apheresis procedures as well as for health professionals working in the field.
(4) The incorporation of three sessions of apheresis, removing 90% of plasma and 30% of platelet population, into the conventional treatment schedule is shown to have an anticoagulant, thrombolytic and platelet hypersensitivity-controlling effect.
(5) The overall CE was calculated from the pre-apheresis cell counts and the stated blood volume processed.
(6) A blood sampling pack is available on closed system apheresis kits for the Fenwal CS3000 blood cell separator to facilitate same day donor testing while maintaining the closed system.
(7) Ethylene oxide gas, which was used to sterilize plastic components in the disposable apheresis kits, represented a possible source of sensitization.
(8) Peripheral stem cell apheresis and lymphocytapheresis are bringing patients with metastatic malignancies to the apheresis department with increasing frequency, and the apheresis staff must be alert to previously undescribed complications of apheresis.
(9) After transfusions which produced satisfactory responses, we identified the original whole blood donors to serve as apheresis donors.
(10) The COBE Spectra System will perform all types of apheresis procedures.
(11) Maintenance lipid apheresis administered 1 time per week resulted in a sustained reduction of total and LDL cholesterol and was associated with a sustained improvement in blood flow properties.
(12) Plateletpheresis was performed on 34 healthy donors (26 male and 8 female), formerly experienced by other apheresis procedures.
(13) HDL-cholesterol levels were somewhat raised, to a higher extent with dextran sulfate apheresis.
(14) A recent development of this procedure is LDL-apheresis, that is the selective removal of atherogenic LDL and the return to the patient of his own LDL-depleted plasma.
(15) A large animal model is needed to evaluate new apheresis technologies.
(16) The patient had received long-term LDL apheresis for 6 years and 7 months and had shown angiographic regression.
(17) These results suggested that LDL-apheresis using the dextran-sulphate cellulose column, may cause an increase in the turnover rate of the apo E-containing HDL and thus facilitate cholesterol removal from the peripheral tissues.
(18) Optimally adjusted anticoagulation under LDL apheresis is essential for successful treatment: Excessive anticoagulation exposes the outpatient to the risk of uncontrolled hemorrhage, insufficient anticoagulation may shorten the duration of utilization of the immune-adsorption columns.
(19) To assure that apheresis procedures are carried out in a safe, efficient and appropriate manner with minimum risk and maximum benefit.
(20) Low-density lipoprotein apheresis (LDL-apheresis) was done with either cascade filtration (DF) or dextran sulfate cellulose adsorption (DSC) in a patient with primary biliary cirrhosis who developed severe dyslipidemia associated with cholestasis and accumulation of lipoprotein-X (LP-X).
Hemapheresis
Definition:
Example Sentences:
(1) Since exposure to blood products occurs on a daily basis during hemapheresis, the acquired immunodeficiency syndrome (AIDS) epidemic has a serious impact both for patients undergoing apheresis procedures as well as for health professionals working in the field.
(2) Selected tests of lymphoid function were used to screen a population of volunteer hemapheresis donors.
(3) To determine organization of autotransfusion in France, two questionnaires were sent to blood centers, anesthetists in 2,100 public hospitals, 50 anesthetists in private clinics and members of the French Hemapheresis Society, requesting information on autotransfusion method, date of installation, applications and persons responsible for its use.
(4) Analysis of the cell volume distribution in suspensions of leukocytes and PBSC collected by hemapheresis showed high recovery of cells after thawing.
(5) However, there have been more than 130 reports describing the use of hemapheresis in children less than 15 years of age, including more than 20 reports describing it in children less than 5 years.
(6) These findings are qualitatively similar to changes reported following intensive lymphocytapheresis and indicate the need for conservative policies regarding donation frequency in hemapheresis programs.
(7) New and innovative applications of automated hemapheresis technology will continue to be developed.
(8) Since these results could not be duplicated routinely in our hemapheresis unit, we set up a study by modifying the standard procedure.
(9) The lack of well-defined indications for treatment and technical difficulties in the management of hemapheresis for small patients have prevented its widespread use.
(10) In hemapheresis procedures carried out for the collection of blood components, healthy donors are subjected to the old familiar risks of blood donation, plus those specifically relating to the use of blood cell separators and to the selective extraction (and loss to the donor) of individual blood components.
(11) As an alternative to automated apheresis for this purpose, manual exchange transfusion is efficacious and does not require hemapheresis instrumentation and disposables and the related special staff.
(12) Hemapheresis has been used in a variety of clinical states, primarily for its ability to remove an offending component, likely be either plasma or cellular elements.
(13) Only one controlled trial of hemapheresis in children has been published.
(14) The changes in all parameters were transient and the increase in hematopoietic progenitor cells were not useful for stem cell harvesting by hemapheresis.
(15) In order to determine whether the rise in blood circulating committed hematopoeitic progenitor cells (CFU-GM) was sustained long enough after exercise to be a practical adjunct to increasing stem cell yields by hemapheresis, the authors evaluated two exercise protocols in 15 normal donors.
(16) Hemapheresis is routinely applied for BM purification in our Dutch Centre, where the buffy coats obtained from routine blood donations were utilised in experimental settings.
(17) This was the major background for the scientific program of the 4th Annual Meeting of the European Society for Hemapheresis that was assembled to shed light on those aspects of the apheresis field which are still unclear.
(18) We report herein the anaphylatoxin levels found with 9 hemapheresis procedures (4 plasma filtration membranes, 3 systems for platelet collection, 2 plasma treatment techniques (dextran sulfate cellulose column and cascade filtration)).
(19) These problems are not insurmountable since several patients less than 1 year of age have been successfully treated by hemapheresis.
(20) In order to investigate collection of committed hematopoietic progenitor cells (CFU-GM) by hemapheresis, four protocols using a discontinuous cell separator (Haemonetics) were evaluated.
