Impact of Willingness to Accept Hepatitis C Seropositive Kidneys Among Hepatitis C RNA-Positive Waitlisted Patients.
BackgroundKidney transplantation from hepatitis C seropositive (HCV+) donors may benefit hepatitis C RNA-positive (RNA+) candidates, but it is unclear how the willingness to be listed for and accept such kidneys affects waitlist and transplant outcomes.MethodsIn a single-center retrospective analysis, HCV+ transplant candidates (N = 169) listed from March 2004 to February 2015 were evaluated. All RNA+ candidates were offered the option to be listed for HCV+ donors. RNA- candidates were listed only for HCV- donors.ResultsFifty-seven patients (51% of all RNA+ transplant candidates) willing to accept HCV+ donors were listed for both HCV+ and HCV- donor kidneys. During 6-year follow up, 43 (75%) of 57 patients accepting HCV+ versus 19 (35%) of 55 patients not accepting HCV+ received a deceased donor kidney transplant (P < 0.0001). Multivariable analysis demonstrated that willingness to be listed for and accept HCV+ kidneys was associated with receiving deceased donor kidney transplant (P = 0.0016). Fewer patients accepting HCV+ donors (7 [12%] vs 16 [29%]) were removed from the list due to death or deteriorated medical condition (P = 0.0117). Posttransplant patient and graft survival rates were not significantly different. Overall patient survival since the listing (combined waitlist and posttransplant survival) was similar among the groups.ConclusionsHCV RNA+ candidates had better access to transplantation and similar overall survival before the era of widespread use of direct-acting anti-HCV agents

Impact of panniculectomy on transplant candidacy of obese patients with chronic kidney disease declined for kidney transplantation because of a high-risk abdominal panniculus: A pilot study.
BackgroundObese patients can develop a large lower abdominal panniculus (worsened by significant weight loss). Patients with advanced chronic kidney disease (CKD) affected by this obesity-related sequela are not infrequently declined for kidney transplantation because of the high risk for serious wound-healing complications. We hypothesized that pretransplant panniculectomy in these patients would (1) render them transplant candidates, and (2) result in low posttransplant wound-complication rates.MethodsIn a pilot study, adult patients with CKD who had a high-risk panniculus as the only absolute contraindication to kidney transplantation subsequently were referred to a plastic surgeon to undergo a panniculectomy in order to become transplant candidates. We analyzed the effect of panniculectomy on (1) transplant candidacy and (2) wait list and transplant outcomes (04/2008-06/2014).ResultsOverall, 36 patients had panniculectomy (median prior weight loss, 38 kg); all were wait-listed with these outcomes: (1) 22 (62%) patients were transplanted; (2) 7 (19%) remain listed; and (3) 7 (19%) were removed from the wait list. Survival after panniculectomy was greater for those transplanted versus not transplanted (at 5 years, 95% vs 35%, respectively; P = .002). For the 22 kidney recipients, posttransplant wound-complication rate was 5% (1 minor subcutaneous hematoma).ConclusionFor obese CKD patients with a high-risk abdominal panniculus, panniculectomy was highly effective in obtaining access to the transplant wait list and successful kidney transplantation. This approach is particularly pertinent for CKD patients because they are disproportionally affected by the obesity epidemic and because obese CKD patients already face multiple other barriers to transplantation
Urologic complications after transplantation of 225 en bloc kidneys from small pediatric donors ≤20 kg: Incidence, management, and impact on graft survival.
Pediatric en bloc kidney transplants (EBKs) from small deceased pediatric donors are associated with increased early graft loss and morbidity. Yet, urologic complications post-EBK and their potential impact on graft survival have not been systematically studied. We retrospectively studied urological complications requiring intervention for 225 EBKs performed at our center January 2005 to September 2017 from donors ≤20 kg into recipients ≥18 years. Overall ureteral complication incidence after EBK was 9.8% (n = 22) (12% vs 2% for EBK donor

Combined Ex Vivo Hypothermic and Normothermic Perfusion for Assessment of High-risk Deceased Donor Human Kidneys for Transplantation.
BackgroundDespite careful clinical examination, procurement biopsy and assessment on hypothermic machine perfusion, a significant number of potentially useable deceased donor kidneys will be discarded because they are deemed unsuitable for transplantation. Ex vivo normothermic perfusion (EVNP) may be useful as a means to further assess high-risk kidneys to determine suitability for transplantation.MethodsFrom June 2014 to October 2015, 7 kidneys (mean donor age, 54.3 years and Kidney Donor Profile Index, 79%) that were initially procured with the intention to transplant were discarded based on a combination of clinical findings, suboptimal biopsies, long cold ischemia time (CIT) and/or poor hypothermic perfusion parameters. They were subsequently placed on EVNP using oxygenated packed red blood cells and supplemental nutrition for a period of 3 hours. Continuous hemodynamic and functional parameters were assessed.ResultsAfter a mean CIT of 43.7 hours, all 7 kidneys appeared viable on EVNP with progressively increasing renal blood flow over the 3-hour period of perfusion. Five of the 7 kidneys had excellent macroscopic appearance, rapid increase in blood flow to 200 to 250 mL/min, urine output of 40 to 260 mL/h and increasing creatinine clearance.ConclusionsFavorable perfusion characteristics and immediate function after a 3-hour course of EVNP suggests that high-risk kidneys subjected to long CIT may have been considered for transplantation. The combined use of ex vivo hypothermic and normothermic perfusion may be a useful strategy to more adequately assess and preserve high-risk kidneys deemed unsuitable for transplantation. A clinical trial will be necessary to validate the usefulness of this approach
