The process of removing certain proteins from the blood. Plasmapheresis can be used to remove excess antibodies from the blood of multiple myeloma patients.
Blood is taken from a vein and circulates through a machine, which separates the cells and the plasma. The plasma is removed and replaced with a substitute, which is returned to the body along with the blood cells.
Removal of a portion of blood, separation of the blood cells by centrifugation so as to remove the plasma portion containing antibodies and replacement with plasma or sterilized albumin separated from donor blood. It is often part of the treatment protocol in myasthenia gravis, Guillain-Barré syndrome, and severe dermatomyositis.
The selective removal of certain proteins or antibodies. This process is sometimes used in the treatment of some peripheral neuropathies.
technique of separating out certain proteins from the plasma. Plasmapheresis is used to treat Guillain Barré syndrome and other illnesses.
The selective removal of certain proteins or antibodies from the blood (followed by reinjection of the blood).
procedure in which blood is withdrawn from the body, its components are selectively separated, undesireable components (e.g., toxins, metabolic substances, and antibodies) causing disease are removed, and the remainder is returned to the body
A process in which plasma is removed from blood and the remaining components, mostly red blood cels, are returned to the donor. The process is used in transplantation to remove pre-formed antibodies.
Generation of blood plasma while re-transfering red and white blood cells to the blood donor
plasma is separated from whole blood and the rest is returned to the donor
Blood is drawn, plasma is separated and withheld, the packed red cells are re-injected.
A therapy in which blood is withdrawn from a patient, the plasma is removed and replaced, and the blood is returned to the patient in a transfusion. This leaves red and white cells in place but removes the antibodies. Plasmapheresis is used to treat several autoimmune diseases but has had mixed success with primary and secondary-progressive MS patients.
A procedure for obtaining plasma from a donor by separating the plasma from the whole blood and returning the rest to the donor, usually with saline solution and albumin (see apheresis).
A process for obtaining blood plasma without depleting the donor or patient of other blood constituents (such as red blood cells) by separating out the plasma from the whole blood and returning the rest to the donor's or patient's circulatory system.
The removal of blood from the body and centrifuging it in order to separate the cellular elements from the plasma. The packed red cells then are suspended in a physiological solution and may be reinjected into the donor or injected into a patient who requiers red cells rather than whole blood.
During this procedure, blood is filtered through a machine that removes the antibody-containing plasma and replaces it with a substitute. Plasmapheresis can be used to temporarily reduce the amount of antibodies in the blood.
the selective removal of components from the blood plasma, after which the plasma is returned to the person from which is was taken.
A procedure designed to deplete the body of blood plasma (the liquid part of the blood) without depleting the body of its blood cells. Whole blood is removed from the body, the plasma is separated from the cells, the cells are suspended in saline, a plasma substitute or donor plasma), and the reconstituted solution may be returned to the patient. The procedure is used to remove excess antibodies from the blood in lupus, multiple sclerosis, multiple myeloma, etc. Plasmapheresis carries with it the same risks as any intravenous procedure. The risk of infection increases with the use of donor plasma, which may carry viral particles despite screening procedures. The procedure is done in a clinic or hospital.
treatment removing blood from and vein and separating the blood cells from the blood plasma. The remaining parts of the blood (mostly red blood cells) are returned through another vein, relieving symptoms of myeloma
Removal of blood from the body and centrifuging it to obtain plasma and packed red blood cells: the blood cells are resuspended in a physiologically compatible solution (usually type-specific fresh frozen plasma or albumin) and returned to the donor or injected into a patient who requires blood cells rather than whole blood.
A treatment for AMD involving about twenty expensive sessions of blood exchange. See the Macular Degeneration FAQ ("What is plasmapheresis, and is it effective?").
Apheresis procedure applied to remove plasma.
A procedure in which blood is removed from a vein and spun in a centrifuge to separate plasma from blood cells. The cells, along with replacement plasma, are then re-injected into the patient's vein.
Removal of plasma (the fluid portion of the blood that does not include cells) from the blood. This fluid contains the antibodies and its removal is an experimental treatment for MS.
The process of separating certain cells from the plasma in the blood by a machine. Only the cells are returned to the person. Plasmapheresis can be used to remove excess antibodies from the blood.
separating out the plasma from the whole blood, replacing the plasma, and returning plasma and original blood cells to the patient
Plasmapheresis (from the Greek plasma, something molded, and apheresis, taking away) is the removal, treatment, and return of (components of) blood plasma from blood circulation. It is thus an extracorporeal therapy.
