    Abstract White kidney transplant candidates have the highest pre-transplant mortality rate compared to other ethnicities. The reason for a higher mortality rate is not well-understood. Estimated post-transplant survival (EPTS) score has been used to predict patient survival after transplant and may be associated with pre-transplant survival. First-time kidney transplant candidates listed between 2015 and 2018 were identified from the Organ Procurement Transplantation Network database. Individuals listed for multiple organs, at multiple centers, and age <18 years were excluded. We examined the impact of ethnicity on waitlist mortality and delisting. A total of 114 806 candidates were included. The study population was categorized into four groups which were 43% white, 28% Black, 19.2% Hispanic, and 9.8% "other ethnicities." At 5.2 years, the cumulative incidences of death and delist were 32%, 31%, 29%, and 26%, respectively. Compared to whites, adjusted subdistribution hazard ratio (aSHR) for death and delist among Black, Hispanics, and "other ethnicities" were 0.92 (95% CI 0.89-0.95), 0.89 (95% CI 0.85-0.91), and 0.76 (95% CI 0.72-0.80) after adjustment by EPTS along with other factors, respectively. After adjusting for EPTS score along with additional confounding factors and functional status at initial listing, white ethnicity was independently associated with an increased risk for death and delist.

    Abstract Introduction: One of the most commonly used immunosuppressants in organ transplant, tacrolimus exhibits wide interpatient and intrapatient variability and narrow therapeutic index that necessitates routine concentration monitoring and dosage adjustments. Availability of modified -release tacrolimus products offer once-daily dosing options. The objective of this review is to highlight and compare available pharmacokinetic (PK) data of extended-release tacrolimus tablets (LCP-TAC) to immediate-release tacrolimus (IR-TAC) in kidney transplant recipients.
    Areas covered: A review of the literature was performed using PubMed and Embase search to identify relevant articles evaluating PK data for LCP-TAC compared to IR-TAC in kidney transplant patients including special populations.
    Expert opinion: LCP-TAC's unique PK profile may be more favorable than IR-TAC. While the clinical impact of these PK differences have not been established, several outcomes are being evaluated in ongoing studies. Results of these studies will add information incrementally to care for kidney transplant patients. Larger prospective studies evaluating kidney and patient survival differences are needed but it is unlikely that they will be conducted. Given that the patent exclusivity of LCP-TAC for the next several years and imminent loss of exclusivity of PR-TAC, our opinion is the use of LCP-TAC will be increasing, especially in Europe.

    Abstract Kidney transplant candidates with high anti-M-type phospholipase A2 receptor antibody activity may be at increased risk for early postkidney transplant recurrence and allograft loss. Pretransplant treatment to induce serological remission may be warranted to improve allograft survival. In this case report, a patient seeking their third kidney transplant, who lost 2 prior living donor transplants from early recurrent membranous nephropathy, underwent pretransplant treatment for membranous nephropathy with serological remission and no evidence of recurrent disease.

    Abstract Purpose of review: Kidney dysfunction is challenging in liver transplant candidates to determine whether it is reversible or not. This review focuses on the pertinent data on how to best approach liver transplant candidates with kidney dysfunction in the current era after implementing the simultaneous liver kidney (SLK) allocation policy and safety net.
    Recent findings: The implementation of the SLK policy inverted the steady rise in SLK transplants and improved the utilization of high-quality kidneys. Access to kidney transplantation following liver transplant alone (LTA) increased with favorable outcomes. Estimating GFR in liver transplant candidates remains challenging, and innovative methods are needed. SLK provided superior patient and graft survival compared to LTA only for patients with advanced CKD and dialysis at least 3 months. SLK can provide immunological protection against kidney rejection in highly sensitized candidates. Post-SLK transplant care is complex, with an increased risk of complications and hospitalization.
    Summary: The SLK policy improved kidney access and utilization. Transplant centers are encouraged, under the safety net, to reserve SLK for liver transplant candidates with advanced CKD or dialysis at least 3 months while allowing lower thresholds for highly sensitized patients. Herein, we propose a practical approach to liver transplant candidates with kidney dysfunction.

    Abstract Purpose of review: Plasma cell dyscrasias encompass a group of hematological disorders characterized by increased production of immunoglobulins by clonal B cells. Kidney involvement is common. Significant advances in the treatment of plasma cell dyscrasias have resulted in improved survival and may permit kidney transplantation in candidates previously denied transplantation. Treatments may also have effects on kidney transplant recipients who develop plasma cell dyscrasias post transplantation.
    Recent finding: The available evidence suggests that transplantation of candidates with nonmultiple myeloma plasma cell dyscrasias provides good outcome with low recurrence rates, so long as the disease has been treated with a complete or good partial response prior to transplantation. Candidates with a history untreated MGRS or a history of multiple myeloma have a high rate of recurrence posttransplant. Kidney transplant recipients who develop plasma cell dyscrasias post transplantation have an increased risk of death and thalidomide-based regimens may increase the risk of rejection.
    Summary: Transplant candidates with a history of plasma cell dyscrasia who are in remission should not be excluded from transplantation. Individuals with multiple myeloma have a high rate of recurrence and myeloma post kidney transplant must be managed carefully.

    Abstract Renal dysfunction in cirrhosis is common and is associated with increased mortality. Identifying and treating reversible causes of renal disease can significantly improve outcomes. The etiology, approach, and evaluation of renal disease in this group of patients is similar to the noncirrhosis patient, with a few specific caveats. Renal disease may be unrelated to the cause of cirrhosis (eg, prerenal acute kidney injury, acute tubular necrosis), occur as a manifestation of the same systemic disease responsible for the liver disease (eg, chronic viral hepatitis B and C infection) or as a consequence of cirrhosis (hepatorenal syndrome). Kidney impairment may be underrecognized in patients with cirrhosis due to over-reliance on creatinine-based glomerular filtration rate equations used in clinical practice. The first steps of evaluation for the renal disease include a thorough medical history to identify the underlying cause of cirrhosis and any potential trigger for renal dysfunction, physical examination, and review of prior laboratory records for baseline renal function. Renal imaging and urinalysis should be performed on all cirrhotic patients with renal dysfunction to establish the presence of urinary obstruction, chronicity and intrinsic renal disease.

    Abstract In 2017, United Network for Organ Sharing (UNOS) established the safety net policy with set criteria for offering kidney transplantation (KT) for patients who developed end-stage renal disease between 60 and 365 days after liver transplant (LT). We provide an update on the impact of the policy. We analyzed UNOS data of liver recipients transplanted between 1987 and 2020 who developed acute kidney injury requiring dialysis within 60 days before or after LT and subsequently listed for KT. We identified 407 patients who were listed for kidney after LT before policy and 248 patients after policy. Median waiting time to KT was shorter after policy (324 days vs. 2827 days). There was a higher proportion of candidates who were listed for subsequent KT within 1-year after policy (94.8% vs. 63.6%). KT rate was also higher after policy (87.7 vs. 30.7 per 100 patient-years at risk). Most importantly, we started to observe a net negative kidney utilization in end-stage liver disease setting (i.e., summation of simultaneous liver kidney and kidney after liver transplant in the first-year after LT has decreased from 1086 to 876 transplants in 2019). Such findings are consistent with a more efficient system and more appropriate allocation of organs.
