RESUMO

Existing literature has demonstrated the significant relationship between race and kidney transplant outcomes; however, there are conflicting and limited data on the influence of donor race or donor-recipient race-matching on pediatric kidney transplant outcomes. Methods: Analysis included kidney-only transplant recipients between ages 2 and 17 from 2000 to 2017 enrolled in the Organ Procurement and Transplantation Network and their associated donors. Multivariable regression models were used to compare outcomes by donor race and donor-recipient race-matched status. Results: Of the total 7343 recipients, 4458 (60.7%) recipients received a kidney from a White donor, 1009 (13.7%) from a Black donor, 1594 (21.7%) from Hispanic donor, and 169 (4.1%) from an Asian donor; 4089 (55.7%) were race-matched. No donor races were significantly associated with transplant outcomes (all P > 0.05). Race-matched status was not associated with graft failure (hazard ratio, 1.03; 95% confidence interval [CI] = 0.89-1.2; P = 0.68), mortality (hazard ratio, 1.1; 95% CI, 0.79-1.53; P = 0.56), acute rejection at 1 y (odds ratio, 0.94; 95% CI, 0.77-1.15; P = 0.53), or delayed graft function (odds ratio, 1.02; 95% CI, 0.80-1.29; P = 0.91). Conclusions: Neither donor race nor race-matched status is associated with better transplant outcomes. Further studies are necessary to confirm the impact of donor race and race-matching more fully on pediatric kidney transplant outcomes.

RESUMO

The number of liver transplant candidates with concomitant renal disease has been steadily rising since the implementation of MELD-based allocation in 2002. Consequently, the number of simultaneous liver-kidney (SLK) transplants being performed each year has also increased. However, the establishment of well-defined criteria for when to choose SLK over liver transplant alone has lagged behind. The lack of clear guidelines has worsened an already large shortage of transplantable kidneys. This article further explores the rationale for and outlines the implementation of the SLK allocation policy.

RESUMO

BACKGROUND: Literature supports equivalent kidney transplant outcomes in adults with systemic lupus erythematosus (SLE) compared with those without SLE. However, there are conflicting and scant data on kidney transplant outcomes, as well as controversy over optimal timing of transplantation, in children and adolescents with SLE. METHODS: Analysis included kidney-only transplant recipients aged 2-21 years from 2000 to 2017 enrolled in the Organ Procurement and Transplant Network (OPTN). The relationship between diagnosis (SLE n = 457, non-SLE glomerular disease n = 4492, and non-SLE non-glomerular disease n = 5605) and transplant outcomes was evaluated. The association between dialysis time and outcomes was analyzed in the SLE group only. RESULTS: In adjusted models, SLE had higher mortality compared with non-SLE glomerular recipients (HR 1.24 CI 1.07-1.44) and non-glomerular recipients (HR 1.42 CI 1.20-1.70). SLE was associated with higher graft failure compared with non-SLE glomerular (HR 1.42 CI 1.20-1.69) and non-glomerular disease (HR 1.67 CI 1.22-2.28). SLE had a higher risk of acute rejection at 1 year compared with non-glomerular disease (HR 1.39 CI 1.03-1.88). There was a decreased risk of delayed graft function compared with non-SLE glomerular disease (HR 0.54, CI 0.36-0.82). There were no significant associations between dialysis time and transplant outcomes in the SLE group. CONCLUSION: SLE in children and adolescents is associated with worse patient and graft survival compared with non-SLE diagnoses. Outcomes in children and adolescents with SLE are not associated with dialysis time. Further studies are needed to assess implications of potential earlier transplantation and shorter time on dialysis prior to transplantation.

RESUMO

Kaposi sarcoma (KS) following kidney transplantation can result from recipient reactivation of latent human herpesvirus 8 (HHV-8) infection or activation of donor-acquired HHV-8 infection. Post-transplant KS typically manifests with cutaneous pathology, but rare cases of renal allograft involvement have been reported. We describe two cases of donor-derived HHV-8 infection in two hepatitis C (HCV) viremia-negative transplant recipients who each received a kidney from a donor with HCV viremia. One recipient did not develop KS while the other presented with acute kidney injury caused by extensive KS infiltration of the renal parenchyma and metastatic disease. This report reviews the literature for cases of KS involving the renal allograft and highlights an unexpected consequence of deliberate HCV-positive organ transplantation.

RESUMO

BACKGROUND: Over the past decade, increases in vascular fellowships and the use of endovascular technology have decreased the general surgery residents' exposure to open vascular surgery. We sought to elucidate whether renal transplant is a safe way to teach general surgery residents the essential tenants of vascular surgery without adversely affecting early patient outcomes. METHODS: All solitary, adult deceased donor kidney transplants performed at the University of Wisconsin from 2011 through 2016 were identified and divided into a resident-assist (RA) and fellow-assist cohorts (FA). DGF, defined by the requirement of dialysis within 1 week of transplant, was the primary outcome. Early graft survival and postoperative complications were considered the secondary endpoints. RESULTS: Of the 774 total cases, there were 228 (29.5%) in the RA cohort and 546 (70.5%) in the FA cohort. The RA and FA cohorts had comparable characteristics, except for a nonclinically significant difference in mean donor creatinine (0.96 vs 0.88mg/dL, p = 0.03). RA cases had a similar DGF rate compared to FA cases (25% vs 26%, p = 0.93). Additionally, there was no difference in 2-year graft survival (93.7% vs 95.5%, p = 0.38), nor the rates of graft thromboses (0.4% vs 0.7%, p = 0.65), incisional hernias (0.9% vs 1.8%, p = 0.35), and ureteral strictures (2.2% vs 1.6%, p = 0.55) between the 2 cohorts. CONCLUSIONS: Resident involvement in renal transplantation has no effect on DGF and early allograft function. Though the procedural involvement of each resident in a case is variable, it seems to be a safe way to teach retroperitoneal vascular exposure and anastomotic techniques.

RESUMO

BACKGROUND: Many strategies regarding timing of native nephrectomies exist for patients with symptomatic polycystic kidney disease (PCKD). METHODS: This is a single-center, retrospective study of 594 adults with PCKD who had renal transplants from 1994 to 2014. Three groups were analyzed: renal transplant-only recipients (tx alone), recipients of simultaneous bilateral nephrectomies and transplant (simultaneous), and recipients with pretransplant bilateral nephrectomies (pre). The primary outcome was graft survival. Secondary outcomes included postoperative complications. RESULTS: Five hundred sixty-five adults with PCKD received kidney transplants (303 tx alone, 161 simultaneous, 27 pre). Ten-year posttransplant graft survival was 68.5%, 63.6%, and 65.7% for tx alone, simultaneous, and precohorts (P = 0.86). No statistically significant differences were observed in rates of postoperative ileus, deep vein thrombosis, small bowel obstruction, urinary stricture, urine leak, hernia formation, and delayed graft function. More wound complications were seen in prepatients (25.9% vs 11.1% tx alone, 5.1% simultaneous; P = 0.03), whereas simultaneous patients had a lower incidence of lymphocele (1.3% vs 11.1% pre, 10.2% tx-alone; P = 0.002). Importantly, simultaneous patients had more renal vascular thromboses (4.4% vs 1.3% tx alone, 0% pre; P = 0.04). 16.3% of renal transplant alone patients required nephrectomy at 10 years follow-up. Twenty-nine patients were referred for transplant having had nephrectomies and were ultimately not transplanted. In 4 of these patients who had data available for analysis, the mean panel-reactive antibody significantly increased after nephrectomy was performed. CONCLUSIONS: Simultaneous bilateral nephrectomy can be safely performed at the time of renal transplantation, however, carries a significantly increased risk of renal vascular thrombosis.
