    Abstract Donor-recipient matching is a highly individualized and complex component of solid organ transplantation. Flowcytometry crossmatching (FC-XM) is an integral step in the matching process that is used to detect pre-formed deleterious anti-donor immunoglobulin. Despite high sensitivity in detecting cell-bound immunoglobulin, FC-XM is not able to determine the source or function of immunoglobulins detected. Monoclonal antibody therapeutic agents used in a clinic can interfere with the interpretation of FC-XM. We combined data from the prospectively maintained Antibody Society database and Human Protein Atlas with a comprehensive literature review of PubMed to summarize known FC-XM-interfering antibody therapeutics and identify potential interferers. We identified eight unique FC-XM-interfering antibody therapeutics. Rituximab (anti-CD20) was the most-cited agent. Daratumuab (anti-CD38) was the newest reported agent. We identified 43 unreported antibody therapeutics that may interfere with FC-XM. As antibody therapeutic agents become more common, identifying and mitigating FC-XM interference will likely become an increased focus for transplant centers.

    Abstract Background: Intraoperative anaphylaxis is a life threatening and multiorgan system hypersensitivity reaction that frequently leads to cessation of operations. Despite the incidence of Cefazolin allergy being on the rise, the cases of anaphylaxis to Cefazolin during surgeries and its management are seldom reported.
    Case presentation: We present two patients with no known beta-lactam allergy and end stage kidney disease who received perioperative intravenous Cefazolin for planned deceased kidney transplant surgery at our academic medical center. Both patients developed anaphylaxes approximately three minutes following the administration of the antibiotic and experienced severe, refractory hypotension that required the use of vasopressors. The severity of the anaphylactic reactions resulted in the cessation of the transplant operation and multiple days of intensive care unit admission.
    Conclusion: Peri-or intraoperative anaphylaxis to Cefazolin is on the rise and its consequences in transplant candidates are even more dire given the pre-existing end organ failure, financial burden for health care system, potential loss of donor organs, and emotional burden for recipients and their families. These are the first two cases of reported Cefazolin-induced anaphylaxis that actually resulted in aborting the kidney transplant operation. In addition, cases of previously reported Type 1 hypersensitivity to Cefazolin as prophylaxis for operations were reviewed and the allergy workups were discussed.

    Abstract Introduction and objectives: Clinical data for older patients with advanced liver disease are limited. This post hoc analysis evaluated the efficacy and safety of terlipressin in patients aged ≥65 years with hepatorenal syndrome using data from 3 Phase III, randomized, placebo-controlled studies (OT-0401, REVERSE, CONFIRM).
    Patients and methods: The pooled population of patients aged ≥65 years (terlipressin, n = 54; placebo, n = 36) was evaluated for hepatorenal syndrome reversal-defined as a serum creatinine level ≤1.5 mg/dL (≤132.6 μmol/L) while receiving terlipressin or placebo, without renal replacement therapy, liver transplantation, or death-and the incidence of renal replacement therapy (RRT). Safety analyses included an assessment of adverse events.
    Results: Hepatorenal syndrome reversal was almost 2-times higher in terlipressin-treated patients compared with patients who received placebo (31.5% vs 16.7%; P = 0.143). Among surviving patients, the need for RRT was significantly reduced in the terlipressin group, with an almost 3-times lower incidence of RRT versus the placebo group (Day 90: 25.0% vs 70.6%; P = 0.005). Among 23 liver-transplant-listed patients, significantly fewer patients in the terlipressin versus placebo group needed RRT by Days 30 and 60 (P = 0.027 each). Fewer patients in the terlipressin group needed RRT post-transplant (P = 0.011). More terlipressin-treated patients who were listed for and received a liver transplant were alive and RRT-free by Day 90. No new safety signals were revealed in the older subpopulation compared with previously published data.
    Conclusions: Terlipressin therapy may lead to clinical improvements in highly vulnerable patients aged ≥65 years with hepatorenal syndrome.

    Abstract Introduction: A critical question facing transplant programs is whether, when, and how to safely accept living kidney donors (LKDs) who have recovered from COVID-19 infection. The purpose of the study is to understand current practices related to accepting these LKDs.
    Methods: We surveyed US transplant programs from 3 September through 3 November 2020. Center level and participant level responses were analyzed.
    Results: A total of 174 respondents from 115 unique centers responded, representing 59% of US LKD programs and 72.4% of 2019 and 72.5% of 2020 LKD volume (Organ Procurement and Transplantation Network-OPTN 2021). In all, 48.6% of responding centers had received inquiries from such LKDs, whereas 44.3% were currently evaluating. A total of 98 donors were in the evaluation phase, whereas 27.8% centers had approved 42 such donors to proceed with donation. A total of 50.8% of participants preferred to wait >3 months, and 91% would wait at least 1 month from onset of infection to LD surgery. The most common reason to exclude LDs was evidence of COVID-19-related AKI (59.8%) even if resolved, followed by COVID-19-related pneumonia (28.7%) and hospitalization (21.3%). The most common concern in accepting such donors was kidney health postdonation (59.2%), followed by risk of transmission to the recipient (55.7%), donor perioperative pulmonary risk (41.4%), and donor pulmonary risk in the future (29.9%).
    Conclusion: Practice patterns for acceptance of COVID-19-recovered LKDs showed considerable variability. Ongoing research and consensus building are needed to guide optimal practices to ensure safety of accepting such donors. Long-term close follow-up of such donors is warranted.

    Abstract Angiosarcomas are extremely rare malignant tumors of vascular origin. We describe a 63-year-old recipient after a kidney transplant who had an angiosarcoma in the lower extremity that presented after new-onset deep venous thrombosis and was not associated with any fistula. There was rapid progression to metastasis and death. We reviewed the literature of this rare malignant tumor in kidney transplant patients.

    Abstract Aim: To determine the incidence of surgical injury during deceased donor organ procurements.
    Methods: Organ damage was classified into three tiers, from 1-3, with the latter rendering the organ non-transplantable. For 12 consecutive months starting in January of 2014, 36 of 58 organ procurement organization's (OPO)'s prospectively submitted quality data regarding organ damage (as reported by the transplanting surgeon and confirmed by the OPO medical director) seen on the procured organ.
    Results: These 36 OPOs recovered 5401 of the nations's 8504 deceased donors for calendar year 2014. A total of 19043 organs procured were prospectively analyzed. Of this total, 59 organs sustained damage making them non-transplantable (0 intestines; 4 pancreata; 5 lungs; 6 livers; 43 kidneys). The class 3 damage was spread over 22 (of 36) reporting OPO's.
    Conclusion: While damage to the procured organ is rare with organ loss being approximately 0.3% of procured organs, loss of potential transplantable organs does occur during procurement.

    Abstract Background: Discussion continues about right vs. left donor nephrectomy (LDN). Left side is preferred due to longer renal vein while right side has been associated with renal vein thrombosis and shorter vessels.
    Methods: A retrospective analysis of UNOS database for adult living donor transplants between 1 January 2000 and 31 December 2009.
    Results: We identified 58 599 living donor transplants, of which 86.1% were LDN. There were no significant differences between the recipients or donors demographics. There were higher rates of delayed graft function in right donor nephrectomy (RDN) recipients with a hazard risk of 1.38 (95% CI 1.24-1.53; p < 0.0001). Primary failure rates were similar. In the RDN group, graft thrombosis as cause of graft failure was statistically higher with a hazard ratio of 1.48 (95% CI 1.18-1.86, p = 0.0004), and graft survival was significantly inferior (p = 0.006 log-rank test). For living donors outcomes, the conversion from laparoscopic to open was higher in the RDN group with an odds ratio of 2.02 (95% CI 1.61-2.52; p < 0.00001). There was no significant difference in vascular complications or re-operation required due to bleeding. Re-operations and re-admissions were higher in the LDN group.
    Conclusion: There are statistical differences between left and right kidney donor nephrectomies on recipient outcomes, but the difference is extremely small. The choice and laterality should be based on center and surgeon preference and experience.
