What happens when a patient who requires irradiated blood products receives non irradiated products? Irradiated or non-irradiated transfusions have many risks involved including elevated potassium levels and graft versus host disease (TA-GVHD).
What are the risks of a non-irradiated blood transfusion?
Irradiated or non-irradiated transfusions have many risks involved including elevated potassium levels and graft versus host disease (TA-GVHD). Irradiated blood is able to destroy the leukocytes responsible for TA-GVHD, but it adversely causes elevated extracellular potassium due to hemolysis of the RBC's.
What is transfusion with irradiated blood?
Transfusion with irradiated blood prevents these patients from developing transfusion-associated graft versus host disease (TA-GVHD), which is rare, but usually fatal.
What is the difference between irradiated and non-irradiated blood products?
Patients will receive irradiated or non-irradiated blood based on their age. Patients under 4 months of age will receive irradiated blood products, as per hospital protocol, while patients over 4 months of age will receive non-irradiated blood products.
What are the indications for irradiated blood products?
Indications for irradiated blood products. IUT, intra-uterine transfusion; ET, exchange transfusion; SCID, severe combined immune-deficiency; BMT, bone marrow transplant; TA-GVHD, transfusion-associated graft versus host disease; TBI, total body irradiation.
What happens when a patients require irradiated blood?
What are the side effects and hazards? Ionising irradiation of red cells causes an increase in the level of extracellular potassium. The clinical significance of the potassium load depends on the speed and volume of the transfusion, as well as the age of the blood.
When do you need irradiated blood products?
As described in the Technical Manual (20th Edition) and Circular of Information (October 2017), cellular blood components are irradiated prior to transfusion to prevent the proliferation of viable T lymphocytes which are the immediate cause of Transfusion Associated-Graft Versus Host Disease (TA-GVHD).
Why do some patients require irradiated blood products?
Irradiated blood is blood that has been treated with radiation (by x-rays or other forms of radioactivity) to prevent Transfusion- Associated Graft-versus-Host Disease (TA-GvHD).
Who should not get irradiated blood products?
Immunocompromised patients such asInfants (particularly premature) up to 4, 6, or 12 months depending on institutional policy.Intrauterine transfusion* and/or neonatal exchange transfusion recipients.Congenital immunodeficiency disorders of cellular immunity (i.e., SCID, DiGeorge)*More items...
Which type of transfusion reaction can be prevented by using irradiated blood products?
Viable lymphocytes in the transfused blood component attack host tissues, leading to severe rash, diarrhea, and pancytopenia within 7–10 days of transfusion. TA-GVHD is almost uniformly fatal. There is no treatment, but TA-GVHD can be prevented effectively by providing irradiated blood products.
Do all chemo patients need irradiated blood?
No. Blood is only irradiated for patients at risk of TA-GvHD. Your healthcare team must order it specially for you. Even though your cancer care medical record will show that you need irradiated blood, it's important to wear your MedicAlert Identification so other medical centres or hospitals will know.
What does irradiated blood products mean?
Irradiated blood is blood that has been treated with radiation (by x-rays or other forms of radioactivity) to prevent Transfusion- Associated Graft-versus-Host Disease (TA-GvHD).
What does it mean by irradiated?
Definition of irradiation 1 : exposure to radiation (such as X-rays or alpha particles) 2 : the application of radiation (such as X-rays or gamma rays) for therapeutic purposes or for sterilization (as of food) also : partial or complete sterilization by irradiation.
Do heart transplant patients need irradiated blood?
It is not necessary to provide, at baseline, irradiated blood products in solid organ transplantation, even after transplantation when patients are receiving immunosuppressive therapies (unless patients are being treated with the medications listed in Table 4).
Do lymphoma patients need irradiated blood?
People treated for Hodgkin lymphoma are recommended to have irradiated blood if they ever need a blood transfusion in the future. Irradiating the blood (treating it with X-rays) prevents any donor white blood cells from dividing.
Are all blood products irradiated?
Is all blood routinely irradiated? Red cell and platelet transfusions are not routinely irradiated and need to be irradiated 'on demand' for patients at risk of TA-GvHD. It is important that you remind your medical team of your need for irradiated blood as they have to order it specially.
Who is given irradiated blood?
People who have had CAR T-cell therapy should have irradiated blood products for at least 3 months after their treatment. People who've been treated with certain chemotherapy drugs, including fludarabine, cladribine, bendamustine and pentostatin, should have irradiated blood products for the rest of their lives.
Who needs CMV negative blood?
Most children and adults receiving blood transfusions do not need CMV negative blood. But CMV can cause serious problems for people with weakened immune systems, such as cancer and transplant patients, adversely affecting their eyes, lungs, liver, nervous system and gastrointestinal tract.
Why do Hodgkin's lymphoma patients need irradiated blood?
People treated for Hodgkin lymphoma are recommended to have irradiated blood if they ever need a blood transfusion in the future. Irradiating the blood (treating it with X-rays) prevents any donor white blood cells from dividing.
How to identify blood product irradiation?
Blood product irradiation is identified using the Radsure™ system. A label is applied to the blood pack prior to irradiation. The words NOT IRRADIATED are visible. Once irradiation has taken place, the word IRRADIATED remains visible.
Why is timing important in neonatal irradiation?
Timing of irradiation is important for neonatal and paediatric patients. Irradiation reduces the storage-life of red cells and whole blood.
How long does a red blood cell pack last?
Packs irradiated within 14 days of collection expire 28 days after collection. Packs irradiated more than 14 days after collection expire either 5 days after irradiation OR at original expiry of pack, whichever comes first. In patients where hyperkalaemia is a concern, red cells should be transfused within 24 hours of irradiation. Examples include large volume neonatal transfusion such as exchange transfusion, ECLS or rapid large volume transfusion.
What are some examples of large volume transfusions?
Examples include large volume neonatal transfusion such as exchange transfusion, ECLS or rapid large volume transfusion. Irradiation of platelets has not been shown to cause any clinically significant change in platelet function. Platelets may be irradiated at any stage during their 5 day storage life.
How long does it take for a rash to appear after a blood transfusion?
Typically the condition presents 10-14 days after transfusion with rash (erythroderma), pancytopenia and abnormal liver function. There is a longer time between transfusion and presentation in neonates.
What is the main stay of preventing TA-GVHD?
The main stay of preventing TA-GVHD is gamma irradiation of blood products. Leukocyte depletion using current technology is inadequate for this purpose.
Do platelets get irradiated in Victoria?
In Victoria all platelets are irradiated by ARCBS prior to issue. Irradiation of granulocytes. There is conflicting evidence of irradiation damage to granulocytes. Granulocytes should be transfused as soon as possible after collection and irradiation.
Do immunocompromised patients need blood transfusions?
Patients presenting for surgery who are immunocompromised may require a blood transfusion. Some of these patients will require irradiated blood ( Table 1 ).
Is blood transfusion therapeutic?
Although transfusion of blood products should be therapeutic, it is not without serious complications, including death. It is therefore prudent to follow the advice of Alter et al. [ 3 ]: ‘blood transfusion is like a marriage; it should not be entered upon lightly, unadvisedly or wantonly or more often than absolutely necessary’.
How is blood irradiated?
How Blood is Irradiated. Blood is irradiated by exposing the bags to gamma radiation from cobalt-60 or cesium-137 using an instrument called an irradiator. The minimum radiation dose to kill the T-lymphocytes of 25 Gy10. Another method uses X-rays generated by a linear accelerator.
What is irradiated blood used for?
Irradiated blood is used to prevent transfusion-associated graft-versus host disease (TA-GvHD) in people who received bone marrow transplants or transfusions of blood components.
What happens if you irradiate a T lymphocyte?
The irradiation process kills the donor’s T-lymphocytes which are the main cause of TA-GvHD. Unless the T-lymphocytes are destroyed, they will graft themselves in the recipient’s tissues. If the person’s own immune system is incapable of mounting an immune response to them, the T-lymphocytes get the upper hand and attack the recipient’s body as if it were a foreign invader.
How long can you keep X-rays?
Another method uses X-rays generated by a linear accelerator. When irradiating just red blood cells, they should be treated within 14 days of their expiration date and stored for a maximum of 28 days or until their expiration, whichever comes first.
Does blood become radioactive after irradiation?
Blood does not become radioactive after it is irradiated, and it does not present a danger to the recipient or their family members. The process does not damage healthy blood cells or platelets, but it does shorten the shelf life slightly because the cells lose some of their salt content.
Is TA-GvHD a risk?
The risk of developing TA-GvHD is small, but patients who should take the precaution of using irradiated blood include those with a weakened immune system due to Hodgkin’s disease, people who have taken certain chemotherapy drugs, unborn babies, and babies who need exchange transfusions.
