Background: Simultaneous liver-kidney transplantation (SLKT) is increasingly used for patients with concurrent end-stage liver and renal disease. Emerging evidence suggests that simultaneous liver transplant can provide a tolerogenic benefit to multiorgan transplant recipients. Posttransplant donor-specific antibody (DSA) may be associated with worse outcomes; however, the role for testing DSA in SLKT is unclear.

This review focuses on obesity and social determinants of health as potential barriers to the expansion of living kidney donation.
Recent Findings: The growing rate of obesity and associated metabolic syndrome make many potential donors unacceptable as donor candidates because of the future risk for developing chronic health conditions, such as hypertension and diabetes.
Significant advances in immunosuppressive therapies have been made in renal transplantation, leading to increased allograft and patient survival. Despite improvement in overall patient survival, patients continue to require management of persistent post-transplant hyperparathyroidism. Medications that treat persistent hyperparathyroidism include vitamin D, vitamin D analogues, and calcimimetics.

Methods: We conducted a single-center randomized controlled trial involving 40 stable kidney transplant recipients over 1 year. In the INT arm, the dose of tac was reduced by 15% if the MRE was less than 20% and was increased by 15% if the MRE was greater than 60%.
Background: Immune responses to tissue-restricted self-antigens are thought to play a role in chronic rejection after solid organ transplantation. De novo development of antibodies (Abs) to vimentin have been reported to be associated with interstitial fibrosis/tubular atrophy after kidney transplant, and it has been suggested that immunoglobulin isotype switching of Abs to vimentin may occur during this process. We aimed to determine the correlation between immunoglobulin isotype switching of Abs to vimentin and development of transplant glomerulopathy (TG) after kidney transplant, and to determine whether citrullinated modification of vimentin is required for de novo anti-vimentin development.

We investigated the role of immune responses to donor human leukocyte antigens (HLA) and tissue-restricted kidney and pancreas self-antigens (KSAgs and PSAgs, respectively) in SKP Tx recipients (SKP TxRs). Sera collected from 39 SKP TxRs were used to determine de novo Abs specific for KSAgs (collagen-IV, Col-IV; fibronectin, FN) and PSAgs (insulin, islet cells, glutamic acid decarboxylase, and pancreas-associated protein-1) by ELISA.

Methods: We reviewed our experience at a single center and compared it to Organ Procurement and Transplantation Network (OPTN) registry data and only included 2-haplotype HLA-matched white living kidney transplants recipients between 2000 and 2013.
Dabigatran is a direct thrombin inhibitor which is approved by the Food and Drug Administration (FDA) for prevention of embolic stroke in patients with atrial fibrillation. Dabigatran has been shown to be non- inferior to warfarin in preventing stroke in patients with atrial fibrillation [1, 6]. The rate of major bleeding in patients taking dabigatran is also similar to that seen in patients on warfarin [1].

In recent years the definition and categorization of kidney disease has been standardized. There are concerns that this standardization has led to an increase in the number of older individuals labeled as having CKD.

No antidote is available for reversal of dabigatran's anticoagulant effect. Despite limited clinical data, hemodialysis has been suggested as a strategy to remove dabigatran during acute bleeding.
