Transplantation of human organs and tissues1 saves many lives and restores essential functions in circumstances when no medical alternative of comparable effectiveness exists. (who.int)
The transplantation of solid organs, such as kidney, liver, heart or lung, is increasingly a regular component of health care in all countries, and is no longer a feature of health care in high-income countries alone. (who.int)
For example, in developing and developed countries alike, kidney transplantation not only yields survival rates and quality-of-life that are far superior to those obtained with other treatments for end-stage renal disease, such as haemodialysis, but is also less costly in the long run. (who.int)
Nonetheless, the transplantation of organs and tissues does raise ethical concerns. (who.int)
Organ Transplantation.2 These Guiding Principles - whose emphases include voluntary donation, noncommercialization, genetic relation of recipients to donors and a preference for cadavers over living donors as sources - have considerably influenced professional codes, national, state and provincial legislation, and the policies of intergovernmental organizations. (who.int)
The persistent and widening gap between patients' need for organs and the number available for transplantation has become a major concern to many Member States. (who.int)
Access to transplantation entails more than the surgery itself, because success is measured by longer survival of the patient and a long-term improvement in the quality of life. (who.int)
Successful transplantation of organs and living tissues depends on continued medical follow-up and the patient's compliance with a regimen of immunosuppressive drugs. (who.int)
Advantages of living donation for the recipient include shorter waiting times and shorter cold ischemic times for explanted organs, largely because transplantation can be scheduled to optimize the patient's condition. (msdmanuals.com)
Despite continued improvement in short-term graft survival, late allograft dysfunction remains a significant problem in the clinic, especially in kidney transplant patients. (hindawi.com)
Many factors contribute to late graft dysfunction, and among them immunological factors are the leading cause of late grafts loss. (hindawi.com)
However, chronic allograft dysfunction in the form of bronchiolitis obliterans remains a major hurdle that threatens both the quality of life and long-term survival of the recipients. (ersjournals.com)

Specifically, CD39 has important functions in down regulating inflammatory processes and modulating innate immune responses within transplanted organs and at sites of inflammation in the liver and gastrointestinal tract. (bidmc.org)
One technical challenge that has thus far limited the development of a tissue-engineered liver graft is oxygen and nutrient transport. (elsevierpure.com)
Here we demonstrate a novel approach to generate transplantable liver grafts using decellularized liver matrix. (elsevierpure.com)
The recellularized graft supports liver-specific function including albumin secretion, urea synthesis and cytochrome P450 expression at comparable levels to normal liver in vitro. (elsevierpure.com)
The recellularized liver grafts can be transplanted into rats, supporting hepatocyte survival and function with minimal ischemic damage. (elsevierpure.com)

Cardiac1
Organ shortage is a major public health issue, and patients who die after out-of-hospital cardiac arrest (OHCA) could be a valuable source of organs. (springeropen.com)
Rejection7
Here we focused on antibody-mediated rejection (AMR), as AMR is emerging as a major barrier to long-term graft survival, and the donor-specific antibodies are directly involved in AMR. (hindawi.com)
Donor-specific antibodies (DSA) are associated with acute kidneygraft rejection, but their role in small bowel/multivisceral allograft remains unclear. (lww.com)
The clinical rejection episodes in allografts were significantly associated with the presence of DSA ( P =0.041).We obtained 291 biopsy samples from graft ileum and date-matched DSA assay reports. (lww.com)

Renal1
Kidney-transplant data from the United Network for Organ Sharing Renal Transplant Registry were used to calculate graft-survival rates with Kaplan-Meier analysis. (nih.gov)
Cadaveric2
Despite greater histoincompatibility, the survival rates of these kidneys are higher than those of cadaveric kidneys. (nih.gov)
The supply of cadaveric organs is limited by an inadequately informed and educated public, inefficient or non-existent organizations for procuring transplant material, and cultural and religious barriers in some countries. (who.int)
Kidneys4
We examined the factors influencing the high survival rates of spousal-donor kidneys. (nih.gov)
Spouses are an important source of living-donor kidney grafts because, despite poor HLA matching, the graft-survival rate is similar to that of parental-donor kidneys. (nih.gov)
This high rate of survival is attributed to the fact that the kidneys were uniformly healthy. (nih.gov)
Kidneys are very versatile organs, and most people can manage perfectly well with only 15% kidney function. (maxhealthcare.in)
Reactivity2
These three review papers provide an extensive overview on antibody reactivity and its correlation with late graft injury. (hindawi.com)

Inflammation1
High-level expression of CD39 using gene therapeutic modalities, following transgenesis or by infusion of soluble, pharmacologically active derivatives has salutary effects on both vascular injury, global inflammation as in colitis or hepatitis and also impacts graft survival. (bidmc.org)
Heart6
The most common procedure is to take a working heart from a recently deceased organ donor (allograft) and implant it into the patient. (wikipedia.org)
Most surgeons endeavour to cut blood vessels as close as possible to the heart to leave room for trimming, especially if the donor heart is of a different size than the original organ. (wikipedia.org)
Once the donor organs are functioning normally, the heart-lung machine is withdrawn, and the chest is closed. (wikipedia.org)
We have harvested the heart explants with the transplanted grafts as well as other organs from all transplanted animals and performed histological analysis to determine the effect of different immunosuppression regimens on graft survival and cell proliferation in vivo. (ca.gov)

Solid-organ transplantations have become the therapeutic option of choice for end-stage organ failure. (medscape.com)
Patients6
The growth in the number of patients wanting or waiting for a transplant has outpaced the supply of available organs. (medscape.com)
Thirteen patients (15 grafts) were serially evaluated for DSA levels pre- and posttransplant. (lww.com)
Now, a follow-up investigation by the same team, in collaboration with researchers at 13 other medical institutions in the United States, has shown that two proteins found in deceased donor urine can be measured to define which donor organs - including those with AKI - are the best candidates for saving the lives of patients with kidney failure. (newswise.com)
Here, our objective was to identify factors associated with organ donation after brain death complicating OHCA, in unselected patients entered into a comprehensive real-life registry covering a well-defined geographic area. (springeropen.com)
4% of patients who died in ICU after OHCA led to organ donation. (springeropen.com)
Patients with OHCA constitute a valuable source of donated organs, and special attention should be paid to young patients with OHCA of neurological cause. (springeropen.com)
Immune4
There are evidences that characters in early immune responses may also affect late graft function. (hindawi.com)
The second area of study is to understand the regulation of the immune response to cellular and solid organ grafts. (stanford.edu)
However, the same immunosuppressive medications that are required to prevent the child's immune system from attacking and rejecting the transplanted organ can predispose these individuals to developing a very serious cancer that is linked to Epstein-Barr virus (EBV). (stanford.edu)
