The first investigational transplantation of a genetically engineered, nonhuman kidney to a human body was recently completed at NYU Langone Health—marking a major step forward in potentially utilizing an alternative supply of organs for people facing life-threatening disease.
After a liver transplant, patients have to take immune-suppressing drugs for the rest of their lives. These so-called immunosuppressants prevent the organ from being rejected. However, the drugs increase the risk of cancer and serious infections. They can also significantly impair kidney function and even lead to dialysis. In order to be able to give those affected as much immunosuppression as…
Researchers have found a way to reduce organ rejection following a transplant by using a special polymer to coat blood vessels on the organ to be transplanted. The polymer, developed by Prof. Dr. Jayachandran Kizhakkedathu and his team at the Centre for Blood Research and Life Sciences Institute at the University of British Columbia, substantially diminished rejection of transplants in mice when…
A European comparative study has evaluated national organ donation policies in seven countries from an ethical perspective. For the first time, knowledge and attitudes towards organ donation regulations in different European countries were investigated in combination. The study was published in the journal PLOSone.
Handheld laser devices that help surgeons quickly spot liver damage could transform transplant procedures, research suggests. The non-invasive technique could provide medical staff with instant data on the health of donor livers and help them to identify which organs are suitable for transplant. If widely adopted, the light-based tool could allow more livers to be transplanted safely and…
Researchers from the Canadian University Healh Network (UHN) have developed and validated a deep learning model to predict a patient's long-term outcome after receiving a liver transplant. First of its kind in the field of Transplantation, this model is the result of a collaboration between the Ajmera Transplant Centre and Peter Munk Cardiac Centre (PMCC). The study, published in Lancet Digital…
Researchers at the Human Genome and Stem Cell Research Center (HUG-CELL), hosted by the University of São Paulo’s Institute of Biosciences (IB-USP) in Brazil, have developed a technique to reconstruct and produce livers in the laboratory. The proof-of-concept study was conducted with rat livers. In the next stage of their research, the scientists will adapt the technique for the production of…
A potential new treatment to protect immunosuppressed patients from human cytomegalovirus (HCMV) has been discovered by scientists at the University of Cambridge. Their study shows that certain epigenetic inhibitors expose and help to destroy dormant HCMV infections, which often reactivate to cause serious illness and death in these vulnerable groups. Subject to clinical trials, their proposed…
New research indicates that subtle structural features of donated kidneys from living donors may predict the risk of kidney transplant failure in recipients. The findings, which appear in an upcoming issue of JASN, may help clinicians as they evaluate the quality of organs at the time of transplantation. The quality of donated kidneys obtained from living donors is often inferred from their age,…
Researchers from the University Hospital Zurich, ETH Zurich, Wyss Zurich and the University of Zurich have developed a machine that repairs injured human livers and keeps them alive outside the body for one week. This breakthrough may increase the number of available organs for transplantation, saving many lives of patients with severe liver diseases or cancer. Until now, livers could be stored…
Early non-invasive detection of kidney rejection after transplantation was the central aim of a collaboration between Prof. Dr. Bernhard Banas, Chairman of Nephrology at the University Hospital Regensburg (UKR) and the medical diagnostics company, numares. The results of their joint clinical trial “UMBRELLA” were just published in EBioMedicine and presented at the American Society of…
Our eyes – considered by many to be the windows to the soul – need constant care, and as we age, they sometimes also need significant repair. The panes of these windows – the corneas – are transparent tissues that have been the focus of some of the oldest and most common transplantation surgeries. Now thanks to researchers in Kyoto, some such transplants may become even safer. The team,…
For patients with Type 1 diabetes who don’t respond well to insulin or have other serious medical complications caused by their disease, pancreas transplantation offers hope for a cure. But obese candidates who need a pancreas transplant often are denied the procedure because of poor outcomes, including high rates of incision infections, which are linked to an increased risk for failure and…
The consequences of organ rejection in transplant patients can be devastating. Professor A. Vathsala, co-director of the National University Centre for Organ Transplantation at the National University Hospital (NUH) and professor of medicine, says that between 30 percent to 40 percent of kidney transplants are lost over time to rejection. She and Associate Professor Paul MacAry of the Department…
‘Do we want transplant medicine? And if yes, what are we prepared to change in public policy, society and medicine?’ This question characterises the current situation within this medical discipline. Since the 2011 transplant scandal, there has been a steady decline in organ donations according to the German Foundation for Organ Donation (DSO). Although there were some 1,200 transplant donors…
New research indicates that many kidneys obtained for transplantation from deceased donors are not being used because of biopsy findings despite their unreliability and reproducibility. The findings, which appear in an upcoming issue of the Clinical Journal of the American Society of Nephrology (CJASN) and will be published at ASN Kidney Week 2018, may suggest an urgent need to re-examine the…
A DNA-based analysis of blood cells soon after a stem cell transplant can predict likelihood of disease recurrence in patients with myelodysplastic syndrome (MDS), a group of cancerous disorders characterized by dysfunctional blood cells. Such a practice could help doctors identify patients at high risk of disease recurrence early after a transplant and help guide treatment decisions.
A new study found that increased utilization of split liver transplantation could decrease the number of children who die awaiting liver transplantation without decreasing liver transplantation access for adult patients. “Among children listed for liver transplant in the United States, more than one in 10 infants and one in 20 older children die while waiting for a liver,” says Emily Perito,…
A new study indicates that many donated organs that are discarded might be suitable for transplantation if certain steps are taken to limit damage following donation. The findings appear in an upcoming issue of the Journal of the American Society of Nephrology (JASN). In most cases in the United States, transplant organs come from donors following brain death, in which all the functions of the…
Researchers in Germany have demonstrated that hematopoietic stem cell (HSC) transplants can be improved by treatments that temporarily prevent the stem cells from dying.
Whilst Spain has announced a new record for organ donations the number in Germany is stabilising at a ‘low level’. The good news? The number did not fall any further following scandals surrounding the manipulation in the allocation of donor organs.
The results of a new study suggest that high discard rates among donated kidneys could be avoided in the future. Researchers say that even kidneys with poor biopsy results may be more efficient in prolonging patients' lifespans than other treatments.
Surgeons at Johns Hopkins Medicine report that their first series of a minimally invasive procedure to treat chronic pancreas disease, known as severe pancreatitis, resulted in shorter hospital stays, less need for opioids and fewer complications, compared with standard surgical approaches.
Certain white blood cells play an important role in bringing a harmful virus under control after kidney transplantations. The results of a research group at the Department of Biomedicine at the University of Basel and University Hospital Basel could contribute to improving control of immunosuppression, avoiding transplant rejection and developing relevant vaccines.
Approximately 30,000 organ transplants occur in the United States each year. However, between 20 and 50 percent—depending on the organ type—of the transplanted organs fail within five years, most often because the recipient’s immune system attacks, or “rejects,” the donated organ.
