solid organ transplant

The PGY2 Solid Organ Transplant Pharmacy resident will be an integral part of the health care team for each transplant service, providing comprehensive pharmacotherapy services including pre-transplant evaluations, documenting per CMS requirements, medication acquisition for post-transplant patients, pharmacokinetic monitoring, and patient education. Acute rejection is mediated by T and B lymphocytes and occurs normally within the first year after transplantation. When properly combined with immunosuppressive regimes currently used in SOT, MSCs would potentially allow tolerance induction and/or minimize the use of immunosuppressive drugs. The overall median age was 57 years, and 59% were men. Patients with HCC must now wait 6 months from the time of HCC diagnosis until they can undergo transplant with a deceased donor graft. Maricar Malinis, MD FACP, FIDSA. 5). An ongoing concern in the field of solid organ transplantation is the increasing disparity among supply, demand, and distribution. When tissues are transplanted with mismatched HLA, this can elicit a very strong cytotoxic T cell immune response against transplanted tissues. Some people fnd instant relief from long-term pain or health problems. The direct measurement of immunosuppressant drugs for TDM purposes has been mainly based on immunoassays (Table 4.11) which are suited for routine laboratory analyses with excellent automation and high throughput. Avery RK. They may rely on lay leadership or on a skilled group therapist. When donor dendritic cells carry mismatched HLA at their cell surface, recipient T cells can recognize polymorphic residues on the HLA molecule itself. Caroline D. Hoemann, Martin Guimond, in Encyclopedia of Biomedical Engineering, 2019. 5) which could explain why the risk of acute rejection tends to diminish with time as donor dendritic cells are replaced by recipient dendritic cells. The stage of asymptomatic hyperuricemia lasts for 20 to 30 years in classic gout but is present for only 6 months to 4 years in cyclosporine-induced disease. Solid organ transplantation is an accepted, successful, and commonly employed treatment option... Hepatocellular Carcinoma. Thomas G. Gross, in Abeloff's Clinical Oncology (Fifth Edition), 2014, Although SOT has been used as part of the treatment of some cancers—primarily unresectable liver tumors—concern exists about increased risk of recurrence in patients with a history of cancer after SOT. Solid organ transplantation is a treatment option for end-stage organ failure of the kidneys, liver, pancreas, heart, and lung. In 2006, 4,252 transplanted kidneys came from deceased donors and 3,751 kidney transplants came from live donors. This study provided evidence for the increased level of IL-10 mediating improved survival. As macrophages are present in almost all the tissues in the body and are considered to be major mediators of inflammation and its subsequent resolution, the interactions between MSCs and macrophages could have significant implications in the therapeutic potential of MSCs in transplantation medicine. Owen S. Surman M.D., Laura M. Prager M.D., in Massachusetts General Hospital Handbook of General Hospital Psychiatry (Sixth Edition), 2010. The ISHLT COVID-19 Task Force applauds Dr Boyarsky et al for their initiative in studying immune responses to SARS-CoV-2 vaccination in solid organ transplant (SOT) recipients (1). The risk of reactivation in chronically infected recipients is highest in the first year after transplant, and subsequently with intensification of immunosuppression. First is the ever-present potential for allograft rejection. In addition, MiHAs with subtle structural differences can also trigger T cell immune responses against transplants. Biologic agents (e.g., belatacept) are on the horizon, and might replace current immunosuppressants in the near future (Kaplan, 2015). Currently, there are over 93,000 persons on the waiting list for a solid organ transplantation, but only 17,000 transplants were done between January and July of 2006.1 Some European countries follow the doctrine of “presumed consent” for postmortem donation, but the United States does not. Active or completed clinical trials with MSC classified by target use or disease (n: 488). In addition, IKK-2 is essential for effective dendritic cell antigen presentation (Andreakos et al., 2003). The transplantation/solid organ pharmacy residency at the University of Pittsburgh Medical Center (UPMC) is designed for the individual interested in developing specialized clinical expertise in pharmaceutical care for transplant patients. Alloreactivity contributes to chronic graft-rejection and indirect presentation of alloantigen appears important in this process. Solid Organ Transplant Center Children’s Health℠ offers one of the longest-running, most experienced pediatric multi-organ transplant programs in the nation. Solid organ transplantation offers a life-saving therapeutic option to the patients with terminal organ failures. also suggested that in cocultures of MSCs with purified T cells, cell-to-cell contact was required, and coculturing MSCs with unpurified mononuclear cells increased the number of regulator T cells which suggest that multicellular interactions play a role in upregulation of regulatory T cells [39]. MSCs have been shown to suppress the proliferation of effector T cells in response to various cellular and nonspecific mitogen stimulation [35] and hinder antigen recognition of naïve and memory T lymphocytes [36] via various factors, including indoleamine 2,3-dioxygenase (IDO), prostaglandin E2 (PGE2), transforming growth factor beta (TGF-beta), and hepatocyte growth factor (HGF). Some studies suggest similar outcomes in cadaveric and LDLT, whereas other studies have shown an increased risk following LDLT.90 Decision analyses have shown that LDLT for patients with HCC improves life expectancy and is more cost effective than waiting on the transplant list for more than 7 months.91 Because the waiting time before transplantation can be quite short, it is possible that LDLT may result in a higher risk of recurrence, but more studies may be needed.92,93. The scarcity of cadaveric organs creates a mismatch between the number of patients who need transplantation and the number who can undergo transplantation. F. CHRISTOPHER ZUSI Ph.D., ... JAMES R. BURKE Ph.D., in Target Validation in Drug Discovery, 2007. Patients undergoing solid organ transplantation (SOT) or bone marrow or hematopoietic stem cell transplantation (HSCT) can develop posttransplantation lymphoproliferative disorder (PTLD) as a result of immunosuppression. Transplanted organs may contain donor B-lymphocytes capable of producing ABO antibodies. Laura M. Prager MD, in Massachusetts General Hospital Comprehensive Clinical Psychiatry, 2008. Herpesvirus infections in solid organ transplant patients at high risk of primary cytomegalovirus disease. As clinical trials assessing SARS-CoV-2 vaccines excluded patients with SOT, this study is a necessary step to fill that knowledge gap. The greater the immunosuppression, the greater is the risk for developing PTLD. The risk for developing PTLD is greatest (50%−90%) in the first year after transplantation.133 Because HSCT recipients usually have immune reconstitution within 1 year of transplantation, PTLD rarely occurs >1 year after HSCT. Sometimes this is done with surplus tissue, tissue that can regenerate, or tissues more desperately needed elsewhere (examples include skin grafts, vein extraction for CABG, etc.). Fig. Finally, the side effects of immunosuppressive medications that are used to manage rejection can be debilitating, disfiguring, or life-threatening. Liver transplantation is an effective way to remove both the carcinoma and the remaining cirrhotic liver with its propensity for tumorigenesis. Copyright © 2021 Elsevier B.V. or its licensors or contributors. Solid organ transplant recipients (SOTRs) are at increased risk of developing and dying from cancer. Using these criteria yielded an overall 4-year survival rate of 74%, similar to that for patients who received a liver transplant but did not have HCC. By continuing you agree to the use of cookies. However, a small subset of these self-peptides, called minor histocompatibility antigens (MiHAs), are polymorphic and can induce alloreactivity and immune activation in the setting of transplantation. Recipient T cells may also recognize peptide-MHC complexes when MHC molecules are physically similar. Reduction of immunosuppression135 is the first step in treatment for PTLD in SOT patients, despite the risk for rejection.129 Usually azathioprine and mycophenolate mofetil are discontinued, and doses of cyclosporine, tacrolimus, and prednisone are halved. These include (1) ascertaining that a donor's decision to donate part of their organ is voluntary; (2) ensuring a clear understanding by the donor that the procedure, unlike most operations, is not being done for their own medical problem; (3) noting that donation is associated with complications both intraoperatively and postoperatively; and (4) that there is uncertainty if the donor operation affects long-term survival of donors in any way or has an effect on their quality of life. Diagnosis and Management of Infections in Solid Organ Transplant Recipients. Humar A. Reactivation of viruses in solid organ transplant patients receiving cytomegalovirus prophylaxis. The recognition of allogeneic MHC molecules after HLA mismatch organ transplant is called direct allorecognition. During transplantation, ischemia injury can damage endothelial cells and organs affected by chronic rejection undergo obliterative vasculopathy and parenchymal fibrosis that lead to progressive to loss of graft function. This episode of CRACKCast covers Rosen’s chapter 188, The Solid Organ Transplant patient. Our institution sometimes uses a family meeting format for interviewing kidney transplantation patients before placing their name on the cadaveric organ list or proceeding with living-donor evaluation. For others, the healing process takes time. Sangeeta Tanna, Graham Lawson, in Analytical Chemistry for Assessing Medication Adherence, 2016. Murray, Merrill and Harrison at the Peter Bent Brigham Hospital in Boston (Merrill et al., 1956). Table 4.11. For kidney donors, long-term health risks include the development of microalbuminuria and the potential for renal failure in the remaining kidney. Fig. However, long-term administration of immunosuppressive medications has potential unfavorable consequences including increased susceptibility to opportunistic infections and malignancies, and damaging effects on different organ functions like kidney toxicity. For most solid-organ transplantation evaluations, the patient undergoes a standard series of visits with surgery, nursing, psychiatry, social services, anesthesiology, and other medical and paramedical subspecialties as indicated. Treating COVID-19 in solid organ transplant (SOT), hematopoietic cell transplant (HCT), and cellular immunotherapy recipients can be challenging due to the presence of coexisting medical conditions, transplant-related cytopenias, and the need for chronic immunosuppressive therapy to prevent graft rejection and graft-versus-host disease. The UAMS Organ Transplant team has performed … To summarize, antigenic materials that can induce immune activation and organ rejection are MiHAs or peptides derived from HLA molecules or the HLA molecule itself when transplantation is performed between HLA mismatch individuals. The Model for End-Stage Liver Disease (MELD) is also a calculated score that predicts how urgently a patient over 12 years of age will need a transplant within the next 3 months. So far researchers have shown that MSCs affect dendritic cells in a variety of ways, including induction of regulatory phenotypes and suppression of differentiation [51,52]. 2006;82(2 suppl):S9-S14. Most information has been derived from observational studies and/or registry analyses in renal graft recipients and, to a lesser degree, from heart transplant patients. Graft rejection following solid organ transplantation is a complex process involving numerous immune mediators. Finally, we describe emerging data implicating factors beyond the graft, including the microbiome, in susceptibility to rejection. Specifically in SOT, MSCs have already been applied in clinical trials in kidney and liver transplantation. In addition, the maximum MELD exception score they can be given is 34, when previously that was not capped. MSCs can also suppress the maturation of monocytes into dendritic cells [53], which provide another venue for suppression of dendritic cell function by blocking supply of new dendritic cells. PGY2 residencies provide residents with opportunities to function independently as practitioners by conceptualizing and integrating accumulated experience and knowledge and incorporating both into the provision of patient care or other advanced practice settings. Even as progress is made in this area, political and ethical issues may prevent the timely application of this technology in human subjects. While the preliminary results show safety and feasibility of the MSC therapy in SOT, some points need to be refined and standardized. The length of time spent on the waiting list can differ among regions. In SOT patients, immunosuppression is due to medications required to prevent rejection. A successful organ transplant can be the start of a new way of life. Recent estimates of mortality range from 10% to 35% and may be higher in adolescents and in those with multiple sites of disease or CNS involvement, in patients with T- or NK-cell disease, or in EBV-negative or CD20-negative disease.133,153,154 Although no controlled trial is available to guide therapy, attempts to standardize management are based on large case series. Tomas Castro-Dopico, Menna R. Clatworthy, in Kidney Transplantation - Principles and Practice (Eighth Edition), 2019. Printed materials and audiovisual presentations are a useful educational supplement. Jiang et al. Chronic rejection is more insidious and in the long run, it is the leading cause of graft failure in transplanted patients. The dropout rate of some patients with HCC has been reported to be as high as 70%, depending on the tumor burden and the length of time the patient waits for transplantation.88 There is clearly a group of patients who are at a very low risk of dropout (Fig. Data showing an association between dyslipidemia and cardiovascular events are more indicative in nature following liver transplantation and lung transplantation. A growing body of basic, preclinical, and clinical research studies suggests that MSCs may fulfill this need due to a combination of immunomodulatory and tissue protective effects. The challenge of reproducing the highly differentiated neuroendocrine β-cell phenotype is significant, and more investigation in this area is required before stem-cell derived islets will see clinical application. SOT is the best and often only treatment for end-stage organ failure. Solid organ transplantation represents a life-saving or prolonging therapy for hundreds of thousands of patients worldwide. The risk of dissemination and associated complications following active disease warrants lifelong therapy in these patients.132,133, All HIV-positive patients with active coccidioidomycosis and CD4 counts <250 cell/mm3 require antifungal treatment. We herein report our initial experience with solid organ transplant recipients with SARS-CoV-2 infection at two centers during the first 3 weeks of the outbreak in New York City. Paula S. Seal, Peter G. Pappas, in Antibiotic and Chemotherapy (Ninth Edition), 2010, Solid organ transplantation recipients in endemic areas have up to a 9% risk of coccidioidomycosis within 1 year after transplantation.122,131 Fluconazole and ketoconazole doses of 100–200 mg and 200–400 mg/day have been used for primary and secondary prophylaxis, respectively. 2005; 192: 1331-1339. In SOT patients, EBV-naiveté before transplantation (especially when receiving an organ from an EBV seropositive donor) presents a 5- to 10-fold higher risk for PTLD. Table 14-3 summarizes more than 40 years of data from the Israel Penn International Transplant Tumor Registry of risk of recurrence in patients with a history of cancer who have received SOT.74, N. Lawrence Edwards, in Rheumatology (Sixth Edition), 2015, Solid organ transplantation is a field of medicine that has blossomed in the 25 years since the introduction of the calcineurin inhibitor cyclosporine as an antirejection medication. Patients undergoing evaluation for solid organ transplantation (SOT) often have a history of malignancy. There are many keys to success in this complex endeavor, including appropriate donor and recipient selection, minimization of peri-operative allograft (donor organ) injury, appropriate use of anti-rejection and anti-infection medications, and close post-operative surveillance for rejection, infection, and recurrent disease (Figure 32.1). That score, in addition to blood type and distance from the hospital where the donor organs are located, determines waiting-list placement for potential lung transplantation recipients. However, MSCs have also been shown to increase the viability of B cells, so the effect of MSCs may not be entirely inhibitory on B cells [43]. Serologic evidence of disease includes a primary or reactivated EBV response with or without decreasing EBNA titers.137,138 Virologic evidence of disease includes demonstrating the presence of EBV within the lesion by PCR or in situ hybridization. 8.5.2: Haemolysis after ABO-incompatible solid organ transplantation. Because of these poorer results, patients with more tumor burden have been excluded from deceased donor transplantation in the United States. In some centers, a designated psychiatrist works with a specific team, for example, the kidney transplant team. 5). Submission Deadline: October 30, 2018 (Open) Submit Now. ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V. COVID-19 Antibody Testing of Recipients of Solid Organ Transplants is being led by the transplant team at Johns Hopkins. However, graft rejection is a serious complication that can occur after transplantation. Management of the solid organ transplant recipient in pregnancy includes pre‐eclampsia prophylaxis and monitoring, screening for gestational diabetes and fetal growth restriction, graft surveillance and management of immunosuppressive therapy. The effects of MSCs on immune cells other than lymphocytes have also been studied, but to a much lesser degree, so further work is required in this area. Societal mores also impose limitations. The new organ replaces a damaged one. Jaehyup Kim, Peiman Hematti, in Regenerative Medicine Applications in Organ Transplantation, 2014. The current standard of care is the prophylactic treatment of graft rejection by inhibiting the activation of T cells with immunosuppressive drugs, such as cyclosporine and mycophenolate mefetil, as well as the inhibition of cytokine production and activity by glucocorticoids and the anti-IL2R antibodies. Direct and indirect presentation in the context of organ transplant. In renal transplant recipients, lipid lowering with a statin has been shown to reduce cardiac morbidity and mortality in a large randomized controlled trial.9,10 There are also indications from two randomized trials in heart transplant patients that lipid lowering with statin therapy has a preventive cardiovascular effect,11–13 although benefits were largely focused on pleiotrophic effects (inflammatory and immune modulating). UT Southwestern doctors completed the first kidney transplant in North Texas more than 50 years ago. Laura Carreras-Planella, ... ... SOT is the best and often only treatment for end-stage organ failure. Transplantation. Due to cultural differences leading to drastically different rates of deceased donation, LDLT is much more common in India and Asia compared with Western countries. Psychiatrists and other mental health professionals are involved in many different aspects of the transplantation process. MSC therapy has been put forward as a possible therapeutic strategy in this setting as MSCs have immunomodulatory, regenerative, and angiogenic properties. Hyper acute graft-rejection can occur rapidly after surgery. The licensed dose is 3–5 mg/kg/day by intravenous infusion, from day –1 until oral maintenance begins. Specific post-operative infections and recurrent disease vary depending on the organ transplanted and recipient characteristics. Pediatric recipients (those patients age 12 and under) for kidneys and livers take priority over adults. Overall, in this small retrospective study of solid organ transplant recipients, the rate of severe COVID-19 was higher than in the general population. UAMS also performed the state’s first liver transplant in 2005. Organ Transplantation. 1). Solid organ transplantation is a widely used treatment for end-stage failure of several organs. Solid organ transplantation is not commonly used in the treatment of cancer, but HCC is an exception. The psychosocial interview complements the process of informed consent and provides an excellent opportunity to instruct patients in relaxation techniques, to counsel them about mobilizing an effective support network, and to inform them about the potential for postoperative mental status change and how it is best addressed. It has to be recognized that differences in biological properties of MSCs derived from different species, differences in immunological assays used, and different animal transplantation models could contribute to the occasional contradictory results among reported studies. Dendritic cells are specialized antigen-presenting cells that can play a role in organ rejection through direct or indirect antigen presentation. In recent years, transplant centers have attempted to expand the donor pool by harvesting organs from persons who have been declared dead secondary to cardiac arrest (i.e., non–heart-beating donors) in addition to harvesting organs from persons who have been declared dead by neurological criteria (i.e., brain death). Guest Editor. MSCs have been shown to inhibit B-cell differentiation and proliferation which is similar to what have been observed with T lymphocytes. What you need to know about solid organ transplants . In SOT patients, PTLD can occur many years after transplantation. Antonio Galleu, Francesco Dazzi, in Cord Blood Stem Cells and Regenerative Medicine, 2015. A definitive diagnosis of PTLD only can be made histologically.139. An alternative to ciclopsorin. #solidorgantransplant #savealifebydonating. Patient groups are similarly effective. Asari et al. Dendritic cells present in transplanted organs are known as passenger leukocytes. Criteria first defined by Mazzaferro et al.,84 referred to as the Milan criteria (Fig. In HSCT patients, immunosuppression begins with the conditioning regimen. In contrast to the accumulated experience from large intervention trials in the general population over the last 10 to 15 years that has demonstrated the benefits of lipid lowering using statin therapy,8 large controlled trials investigating the effect of dyslipidemia treatment on cardiovascular disease in solid organ recipients are scarce. proposed that direct cell-to-cell contact and activation via programmed death ligand 1 (PD-L1) mediates the inhibition of lymphocyte proliferation observed in cocultures with MSCs [38]. reported that dendritic cells cocultured with MSCs were less efficient in stimulating allogeneic T cells [54] and studies by Zhang et al. Juliet A. Emamaullee, A.M. James Shapiro, in Principles of Regenerative Medicine, 2008. suggest that MSCs drive dendritic cells toward Jagged-2 dependent regulatory phenotype, possibly via cell-to-cell contact [55]. Residents who … Many successful transplant recipients enjoy the opportunity to give something back by sharing their experience with new transplant candidates. Thus, the development of nontoxic immunosuppressive-sparing strategies could have a major impact on improving the long-term outcome for transplant recipients. Many patients feel relieved to put a long-term illness and the transplant waiting process behind them. As already detailed above, in vitro and in vivo studies proved the immunomodulatory role of MSC, and beneficial immune modulatory and regenerative effects of MSC have been shown in a myriad of experimental transplant models. However, whether this superiority can be applied to humans remains unknown, since all the available data come from animal models. ScienceDirect ® is a registered trademark of Elsevier B.V.

Although not everyone with high EBV loads in the blood develops PTLD,142,143 most transplantation physicians trend EBV loads to determine which patients are at highest risk for PTLD, so that diagnostic testing can be performed as early as possible.144 Some retrospective data suggest that ganciclovir or acyclovir therapy can reduce the risk for PTLD. Some insurance plans allow inpatient admission to facilitate evaluation, and others require that this process occur on an outpatient basis. As the result, the mortality and donor graft survival rates have significantly improved. In a mouse model of sepsis, Nemeth et al.
