One size does not fit all: Differential benefits of simultaneous liver-kidney transplantation by eligibility criteria.

Standard eligibility criteria for simultaneous liver-kidney transplantation (SLK) are in place in the United States. We hypothesize that the benefit associated with SLK over liver transplant alone differs by patient, depending on the specific SLK criteria met. We analyzed a retrospective US cohort of 5446 adult liver transplant or SLK recipients between January 1, 2015, and December 31, 2018, who are potentially qualified for SLK.

BK virus nephropathy in non-renal solid organ transplant recipients: Are we looking hard enough?

We retrospectively examined the clinical characteristics, pathological features, and outcomes of BK viremia and nephropathy in a population of non-renal solid organ transplant patients (NRSOT) referred for outpatient nephrology consultation over a period of 5 years. In the entire cohort of liver, heart, and lung transplant recipients referred to this clinic, 14% percent were found to have BK viremia with a median peak serum BK viral load of 35 500 copies/ml (range 250 to 21 100 000 copies/ml). BK viremia resolved in six of the seventeen patients (35%).

Definition and Analysis of Textbook Outcome: A Novel Quality Measure in Kidney Transplantation.

Background: "Textbook outcome" (TO) is a novel composite quality measure that encompasses multiple postoperative endpoints, representing the ideal "textbook" hospitalization for complex surgical procedures. We defined TO for kidney transplantation using a cohort from a high-volume institution.

Methods: Adult patients who underwent isolated kidney transplantation at our institution between 2016 and 2019 were included.

Kidney transplant in the COVID era: Cautious optimism and continued vigilance.

The authors comment on the usefulness of a new model to advise centers on risks versus benefits of kidney transplantation during the COVID epidemic. See page 2997 for Massie et al's article.

A population-based study of prevalence and risk factors of chronic kidney disease in León, Nicaragua.

Background: Recent studies have shown an excess of chronic kidney disease (CKD) among younger adult males in the Pacific coastal region of Nicaragua and suggest a non-conventional CKD etiology in this region. These studies have been conducted in small, non-representative populations.

Objectives: We conducted a large population-based cross-sectional study to estimate CKD prevalence in León, Nicaragua, and to evaluate the association between previously investigated risk factors and CKD.

Outcomes in kidney transplant recipients from older living donors.

Background: Previous studies demonstrate that graft survival from older living kidney donors (LD; age>60 years) is worse than younger LD but similar to deceased standard criteria donors (SCD). Limited sample size has precluded more detailed analyses of transplants from older LD.

Methods: Using the United Network for Organ Sharing database from 1994 to 2012, recipients were categorized by donor status: SCD, expanded criteria donor (ECD), or LD (by donor age: <60, 60-64, 65-69, ≥70 years).

The role of therapeutic apheresis in high immunologic risk renal transplantation: a review of current trends.

Immunologic sensitization, defined by the presence of antibodies directed against donor human leukocyte antigen (or so called donor-specific antibodies [DSA]), is common among those awaiting kidney transplantation, and is associated with worse outcomes following transplant. Existing DSA have historically been screened for pretransplant using complement-dependent cytotoxic crossmatching and their risk circumnavigated through policies that prohibit transplants between incompatible donor-recipient pairs. This risk avoidance strategy maximizes outcomes following transplant, but at the expense of limiting access to transplant for sensitized individuals.

Therapeutic apheresis before and after kidney transplantation.

Kidney transplantation is considered the treatment of choice for most individuals with end-stage kidney disease, as well as the most cost-effective renal replacement therapy for the health care system that serves them. Immunologic sensitization, defined by the presence of antibodies directed against foreign HLA (or so called, donor specific antibodies, or DSA), is a significant barrier to kidney transplantation. Further, the presence of DSA is associated with an increase in the incidence of antibody-mediated rejection and decreased graft survival following transplantation.

Positive association of renal insufficiency with agriculture employment and unregulated alcohol consumption in Nicaragua.

Background And Objectives: Endemic renal insufficiency (RI) of unknown etiology is a major public health issue with high mortality in the Pacific coastal regions of Central America. We studied RI in León and Chinandega, Nicaragua, evaluating associations with known risk factors and hypothesized exposures.

Methods: A cross-sectional survey was conducted with assessment of medical, social, and occupational history and exposures in conjunction with measurement of serum creatinine.
