Reasons That Centers Consider SLK • Avoid peri-operative dialysis • Potential to prevent – Non-recovery of pre-operative AKI – Early post-transplant ESRD – Subsequent ESRD and need for later kidney from another donor • May protect center from risk of being exposed to poor outcomes based on LTA Wide Variation in Simultaneous Liver-Kidney Transplants Between Regions Nadim MK et al.

Limitations with Comparing SLK and LTA Outcomes in MELD Era • Only retrospective studies • Lack of: – Appropriate control groups – Standardized selection criteria for SLK – Pre-LTA kidney and/or dialysis data – Data on pre-txp comorbidity • Kidney outcomes after LTA not well characterized • Misclassification with registry data • Differences in liver disease severity? Kidney Biopsy in Liver Transplant Candidates • Pathological abnormalities common • High risk of bleeding complications • Not shown to be better than serum creatinine in predicting: – Post-txp reversibility – Post-txp kidney function – Rate of decline of GFR – Time to ESRD • Should be considered a research tool for now McGuire BM et al.

Continued maintenance dialysis for >90 days post-LTA b. non-recoverable kidney function c. between 90-180 days post-LTA OPTN Kidney Transplantation Committee and the Liver and Intestinal Organ Transplantation Committee (OPTN Policy 3.5.10 and 3.5.10.1). SLK Allocation in MELD Era Summary of Issues • Inadequate characterization of pre-kidney function has limited the establishment of uniform criteria • 3 months duration of severe kidney disease is tipping point for worse outcomes after LTA • CKD defined by impaired kidney function for >3 months • Should restrict SLK to patients with stage 4-5 CKD – No clear benefit for patients not on dialysis – Selects patients with lowest likelihood of renal recovery Proposed Algorithm: SLK vs LTA in Liver Candidates with Kidney Dysfunction Bloom RD et al. Adv Chronic Kidney Dis. 2009;16:268-277. Case Report: Liver Transplant • Transplant nephrology consulted to initiate CRRT • Decision made that patient did not require kidney transplant • Patient had a GI bleed requiring multiple transfusions; transferred to ICU • CRRT initiated • Urine Na <10 mEq/L; urine output decreased to 200-300 mL • 6 days later, underwent OLT • Continued on CVVHD for 48 hours • Remained oliguric on steroids and mycophenolate mofetil for 5 days, then started on tacrolimus 2 mg bid • Discharged, eGFR 20mL/min Polling Question In LTA with GFR <25mL/min, which would you NOT consider? 1.

Transplantation. 2013;96:79-84. Addressing Late Graft Loss • Shift in thinking about the causes of late graft rejection: insufficient immunosuppression and non-adherence to immunosuppressive medication are key factors. • Insufficient immunosuppression may occur during immunosuppressive minimization (tapering) or calcineurin-inhibitor-avoidance • Patients at high risk for non-adherence, specifically young adults who are in the transition phase from pediatric to adult renal services, should be identified. Morath et al. Special Issue: Special Focus – Antibody-Mediated Rejection. Transpl Int. 2012;25:633-645. Increasing Adherence in Transplant Patients • Adherence to immunosuppressant regimens is challenging – Patients commonly take >8 medications/day at multiple specific times – Weekly clinic appointments for ~1 year post-transplantation – Laboratory visits between clinic visits – Significant lifestyle changes to incorporate healthy behaviors • Physicians and other members of the transplant team can help improve adherence by providing education on treatment expectations, management of side effects, and strategies to improve adherence – Schedule of medication-taking – Simplified, more convenient medication regimens (reduced dosing, injectable) – Organizing pills (pill boxes, reminder systems) – Regularly scheduled visits with a provider, even when the patient feels well – Individualize regimen to reduce adverse events and side effects Dosing Frequency, Persistence, and Adherence in Transplant Recipients • 219 patients (45% male; 3±2 years post transplantation) randomized to tacrolimus 145 once daily or 74 twice daily • Persistence at 6 months: 81.5% of the once-daily group vs 71.9% of the twice-daily group remained with the treatment (P=0.0824) • Adherence: 88.2% of the once-daily group and 78.8% of the twice-daily group (P=0.0009) • Doses were missed more frequently in the evening than in in the morning (11.7% vs 14.2%; P=0.0035; twice daily regimen) Kuypers DR et al. Transplantation. 2013;95;333-340. Case Report Management • Patient was treated with steroid pulse, 3 doses of IVIG 70 g, and rituximab 1,000 mg X 2 over 2 weeks • Liver function tests remained normal Conclusions • Candidates for SLK transplant include: – ESRD – Metabolic kidney diseases cured by liver transplant – Other? • AMR is a common cause of death-censored transplant failure • Currently, management of AMR must include maintenance of immunosuppression while optimizing patient adherence and minimizing side effects – Recognize those at risk for low–adherence • Future therapies will address underlying pathophysiology of AMR Participant CME Evaluation • Please take out the Participant CME Post-activity Survey and Evaluation from the back of your packet • If you are not seeking credit, we ask that you still fill out the information pertaining to your degree and specialty, as well as the few questions we will read through now measuring the knowledge and competence you have garnered from this program.
