As 2015 comes to a close, AST would like to wish its members, partners and other transplant professionals a safe and happy holiday season. As we reflect on the past year for the field, we would like to provide the readers of the AST eNews a look at the most accessed articles from the year. Our regular publication will resume Jan. 8.

From Jan. 9: Sirolimus has anti-carcinogenic properties and can be included in maintenance immunosuppressive therapy following kidney transplantation. We investigated sirolimus effects on cancer incidence among kidney recipients. The US transplant registry was linked with 15 population-based cancer registries and national pharmacy claims. Recipients contributed sirolimus-exposed time when sirolimus claims were filled, and unexposed time when other immunosuppressant claims were filled without sirolimus. Cox regression was used to estimate associations with overall and specific cancer incidence, excluding nonmelanoma skin cancers (not captured in cancer registries).

From Sept. 18: Burnout is a response to chronic strain within the workplace and is common across nursing professions. Little has been published about burnout in organ transplant nurses. The aim of this study was to report the prevalence of the 3 main components of burnout (emotional exhaustion, depersonalization, and reduced personal accomplishment) in organ transplant nurses and to examine factors that contribute to the development of burnout in transplant nurses.

The UCLA Immunogenetics Center (UIC) provides comprehensive testing for organ and tissue transplantation. Transplant testing has a long history at UCLA. HLA typing was pioneered here in the 1960's. The development of the microcytoxicity test in 1964 marked the beginning of international testing and standardization of HLA typing. The UCLA Immunogenetics Center has retained its leadership position in HLA research, and in the development of accompanying diagnostic testing. MORE

From Oct. 16: BK virus (BKV) causes BKV nephritis in renal transplant patients and contributes significantly to the increase of probability of graft loss. BKV, being latent in the urogenital tract, is likely to be transported with the donor kidney to recipients and following reactivation replicates in the nucleus of renal epithelial tubular cells. BKV daughter viruses are released and enter other renal epithelial cells to spread infection. There are still a lot of unknown factors about the mechanism and kinetics of BKV infection.

From March 6: The need for new approaches to define HLA antibodies, in the context of organ transplantation, is intensely debated among HLA professionals. In this review, we sought to provide background and perspective to current understanding of the immunogenicity of HLA mismatches with respect to the humoral alloimmune response and the definition of B cell epitopes.

From Sept. 4: The Open Payments Program (OPP) was recently implemented to publicly disclose industry payments to physicians, with the goal of enabling patient awareness of potential conflicts of interests. Awareness of OPP, its data, and its implications for transplantation are critical. We used the first wave of OPP data to describe industry payments made to transplant surgeons. Transplant surgeons (N = 297) received a total of $759,654.

From July 10: The new national Kidney Allocation System of the Organ Procurement and Transplantation Network (OPTN), effective as of Dec. 4, 2014, was designed to improve the chances of transplanting the most highly sensitized patients on the waitlist, those with calculated panel reactive antibody values of 98 percent, 99 percent and 100 percent. Recently, it was suggested that these highly sensitized patients will experience inequitable access, given the reported high prevalence of antibodies to HLA-DP, and the fact that only about 1/3 of deceased donors are typed for HLA-DP antigens.

From Nov. 20: Whether warm ischemia during the time to complete the vascular anastomoses determines renal allograft function has not been investigated systematically. We investigated the effect of anastomosis time on allograft outcome in 669 first, single kidney transplantations from brain-dead donors.

From Jan. 30: Unlike antibody-mediated rejection (AMR) with clinical features, it remains unclear whether subclinical AMR should be treated, as its effect on allograft loss is unknown. It is also uncertain if AMR's effect is homogeneous across donor (deceased/live) and (HLA/ABO) antibody types. We compared 219 patients with AMR (77 subclinical, 142 clinical) to controls matched on HLA/ABO-compatibility, donor type, prior transplant, panel reactive antibody (PRA), age and year.

From Dec. 4: The National Organ Transplant Act stipulates that deceased donor organs should be justly and wisely allocated based on sound medical criteria. Allocation schemes are consistent across the country, and specific policies are publicly vetted. Patient selection criteria are largely in the hands of individual organ transplant programs, and consistent standards are less evident. This has been particularly apparent for patients with developmental disabilities (DDs).
