Graft vs. Host Disease (GVHD) occurs when the donor's immune system reacts against the recipient's tissue. (theptctc.org)

We have a series of clinical trials available to evaluate several different strategies to prevent GVHD, such as T cell depletion and the use of novel immunosuppressive agents. (harvard.edu)

On Day+480, the patient is still in complete remission according to PET-CT and MRI, with full donor chimerism, without any GvHD symptoms and immunosuppressive therapy, however, with persistent moderate graft hypofunction (stage 2-3 thrombocytopenia) which required therapy with thrombopoietin receptor agonists. (cttjournal.com)
Management includes controlling systemic acute GVHD with systemic immunosuppressive therapy, controlling pain, and providing local palliative measures. (medscape.com)

Due to high risk of GvHD, nivolumab therapy was stopped 3 months before the proposed allo-SCT, and maintenance therapy was initiated with venetoclax 100 mg/day daily + cytarabine (20 mg intrathecally every 21 days) for relapse prevention. (cttjournal.com)
My principle research interests are in the prevention and therapy of graft-versus-host disease (GVHD) and in the use of graft-versus-leukemia to eradicate blood disorders. (harvard.edu)
The originally produced document was published in 2017 and was informed by the published guidelines on the use of irradiated blood components by the British Committee for Standards in Haematology, 2010, and the guidelines for prevention of transfusion-associated graft-versus-host disease (TA-GVHD) by the Australian and New Zealand Society of Blood Transfusion, 2011. (nacblood.ca)

The relapse rates and acute GVHD rates did not differ between the two groups. (mcmaster.ca)

Issues with T-cell depletion or prophylaxis consisted of trimethoprim-sulfamethoxazole or pentamidine if hematopoiesis was jeopardized. (bio-cavagnou.info)

The Prophylaxis against graft vs. host disease (GVHD) was with cyclosporine plus methylprednisolone. (ectrx.org)

In this prospective trial, results indicated that low-dose PTCy is sufficient to lower acute GVHD in mouse model, partly due to the boosting of fast regulatory T cell (Treg) reconstitution. (biomedcentral.com)

If the GvHD is severe and requires intense immunosuppression involving steroids and additional agents to get under control, the patient may develop severe infections [12] as a result of the immunosuppression and may die of infection. (wikipedia.org)

Individuals received no cytomegalovirus (CMV) specific prophylaxis with ganciclovir or valganciclovir but CMV seronegative individuals received seronegative blood products regardless of the donor's serologic status. (bio-cavagnou.info)

Bone marrow is the place for the production of the hematopoietic cells which differentiate in to three groups: red blood cells, white blood cells and platelets. (longdom.org)
ALL in samples of leukemic blood and bone marrow. (knowcancer.com)
The white blood cells present within the transplanted tissue then attack the recipient's body's cells, which leads to GvHD. (wikipedia.org)
GvHD can also occur after a blood transfusion , known as Transfusion-associated graft-versus-host disease or TA-GvHD if the blood products used have not been gamma irradiated or treated with an approved leukocyte reduction system. (wikipedia.org)
It is not a surgical procedure to place the marrow into the bone, but is similar to receiving a blood transfusion. (theptctc.org)
Over the next 2 to 3 weeks the cells find their way to the bone marrow where they begin to reproduce and establish new, healthy blood cells. (theptctc.org)
