Hyperacute transplant rejection
MONDO:1010186A transplant rejection that appears in the first minutes following transplantation and occurs only in vascularized grafts. This very fast rejection is characterized by vessels thrombosis leading to graft necrosis. Hyperacute rejection is caused by the presence of antidonor antibodies existing in the recipient before transplantation. These antibodies induce both complement activation and stimulation of endothelial cells to secrete Von Willebrand procoagulant factor, resulting in platelet adhesion and aggregation. The result of these series of reactions is the generation of intravascular thrombosis leading to lesion formation and ultimately to graft loss.

Could a cell infusion free organ transplant patients from lifelong drugs?
Disease control Recruiting nowThis early-stage trial tests whether giving a special mix of blood cells after an organ transplant can help the body accept the new organ without needing lifelong anti-rejection drugs. About 10 children and adults receiving kidney, lung, or intestinal transplants will get the cel…

New cell prep method aims to tame transplant complications in kids
Disease control AVAILABLEThis study offers a special way to prepare donor stem cells for children and teens under 22 who need a transplant but lack a perfectly matched sibling donor. The method uses the CliniMACS® system to remove certain immune cells, which may help reduce the risk of graft-versus-host …

Nerve check may predict transplant complication risk
Knowledge-focused Recruiting nowThis study looks at 60 people getting a stem cell transplant to see if their autonomic nervous system (which controls things like heart rate and sweating) can help predict a serious complication called graft-versus-host disease (GvHD). Participants will have simple nerve tests be…
