Long-term social outcome after pediatric kidney transplantation: a single-center experience. Clin Exp Nephrol 2022; 26:368-375. [PMID: 34988725 DOI: 10.1007/s10157-021-02158-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2020] [Accepted: 11/05/2021] [Indexed: 11/03/2022]
Abstract
BACKGROUND Patient and graft survival rates after pediatric kidney transplantation have improved recently. Therefore, the quality of life or social outcome after kidney transplantation has become important for patients and their families. METHODS Patients who underwent kidney transplantation at < 18 years old and were observed for > 10 years were included in this study. The median age at first kidney transplantation was 9.2 (interquartile range [IQR] = 5.6-13.0) years; there were 56 males and 50 females. The median age at last follow-up was 29.9 (IQR = 22.2-36.0) years. We evaluated the patients' renal function, growth, professional status, and marital status at the last follow-up. RESULTS The percentage of functioning grafts at the last follow-up was 81.1%; 73 patients (68.9%) had a first graft. The mean estimated GFR was 51.0 ± 20.5 mL/min/1.73 m2. Twenty patients received dialysis for graft failure. The mean final heights of the males and females were 158.1 ± 9.2 cm (- 2.2 standard deviations) and 149.1 ± 6.4 cm (- 1.7 standard deviations), respectively. Excluding 23 students, 63 patients (75.9%) were employed. Office worker was the most common profession. Twelve patients (14.5%) were unemployed. Of patients > 20 years old, 14 (16.7%), three males and 11 females, were married. Five females had one child each. CONCLUSIONS The graft survival rate was favorable. The final height was short, particularly in male. The rate of employment was relatively high. The rate of marriage and having children were still low. Improving the social outcome is an important problem after pediatric kidney transplantation.

Pediatric renal transplantation; 10 years experience. Turk J Surg 2021; 37:313-317. [PMID: 35677487 PMCID: PMC9130951 DOI: 10.47717/turkjsurg.2021.5319] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2021] [Accepted: 10/12/2021] [Indexed: 12/28/2022]
Abstract
Objectives Although renal transplantation (RT) is the first treatment option for children with end-stage renal failure, the number of transplanted chil- dren remains low compared to adults. Experience of the individual pediatric transplant center is very important in the prognosis of pediatric transplant recipients. In this study, our pediatric RT experience was presented. Material and Methods We retrospectively analyzed the data of 27 patients who had RT in our clinic between April 2009 and April 2019. Results Fifteen of the patients were males, and mean age of all patients was 12.36 ± 4.18 years (range 4-17 years). The most frequent etiology for end- stage renal disease (ESRD) was vesicourethral reflux. Eighteen (66.7%) of the transplanted kidneys came from cadaveric donors and 9 (33.3%) from live donors. One patient had preemptive RT and one patient had a re-RT. Twenty-two patients were on peritoneal dialysis program and four patients were on hemodialysis program. Mean dialysis time before transplantation was 29 (3-104) months. Bleeding was the most common surgical complication. Delayed graft function developed in four patients, and all of their grafts were from cadaveric donors. Rejection developed in 12 of our patients, graft loss was observed in only four of them. Considering all patients, graft survival rates were 100% in the 1st and 3rd years, and 92% in the 5th year. Conclusion Pediatric RT program is difficult to establish, maintain and develop. Complications after transplantation are not uncommon; therefore, early detection and appropriate management are needed. Strategies are still needed to increase post-transplant success.

Long-term outcomes during 37 years of pediatric kidney transplantation: a cohort study comparing ethnic groups. Pediatr Nephrol 2021; 36:1881-1888. [PMID: 33459932 DOI: 10.1007/s00467-020-04908-6] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/31/2020] [Revised: 11/24/2020] [Accepted: 12/22/2020] [Indexed: 11/26/2022]
Abstract
BACKGROUND This study aimed to evaluate short- and long-term outcomes of kidney transplantation over 37 years in a national referral center and compare outcomes between Israeli Jewish and Arab children. METHODS Data on 599 pediatric transplantations performed in 545 children during 1981-2017, including demographic parameters, kidney failure disease profile, and pre-transplant dialysis duration, were retrieved from our computerized database and patient files. Patient and graft survival were estimated using the Kaplan-Meier method. RESULTS Twenty-year patient survival was 91.4% for live donor (LD) and 80.2% for deceased donor (DD) kidney recipients. Respective 10-year and 20-year graft survival rates for first kidney-only transplants were 75.2% and 47.0% for LD and 60.7% and 38.4% for DD grafts. Long-term graft survival improved significantly (p < 0.001) over the study period for recipients of both LD and DD allografts and reached 7-year graft survival of 92.0% and 71.3%, respectively. The proportion of DD transplantations was higher in the Arab subpopulation: 73.8% vs. 48.4% (p < 0.001). Graft survival was not associated with age at transplantation and did not differ between the Arab (N = 202) and Jewish children (N = 343). Median (IQR) waiting time on dialysis did not differ significantly between the Arab and Jewish children: 18 (10-30) and 15 (9-30) months, respectively (p Mann-Whitney = 0.312). CONCLUSIONS Good and progressively improving long-term results were obtained in pediatric kidney transplantation at our national referral center, apparently due to expertise gained over time and advances in immunosuppression. Equal access to DD kidney transplant and similar graft survival were found between ethnic groups.

Abstract
BACKGROUND CKF is an overwhelming illness, especially in children. Kidney transplantation is considered the definitive management of CKF. It has substantial benefits, including increased patient survival, improved skeletal growth, social adjustment, neuropsychological development, and better quality of life compared to chronic dialysis. METHODS This is a retrospective, clinical, observational study in 13 children ≤16 years old who underwent kidney transplantation at IALCH in KwaZulu-Natal, South Africa, from May 2015 to December 2019. RESULTS Over 4 years and 7 months, 13 kidney transplants were performed; 7 (53.8%) were males, and 6 (46.2%) were females. Eleven (84.6%) were Black African and 2 (15.4%) Indian children. The mean age ± (SD) of transplantation was 10.1 ± 2.8 years (range 5.8-15.8). Eight (61.5%) children were from a rural setting. The mean ± (SD) duration of follow-up was 29.5 ± 15.9 months. All kidney transplants done were from live related donors; 8 (61.5%) were parents of the recipients. None were pre-emptive transplants. Graft loss occurred in 2 (15.4%) children with 100% patient survival. Two (15.4%) children developed acute rejection. CONCLUSIONS The commissioning of transplant services in KwaZulu-Natal, South Africa, has improved access to this modality of treatment, particularly in our Black African patients. The significant limitations we experienced were a shortage of cadaveric donors and resource limitations with no dedicated transplant unit for pediatric patients together with staffing constraints. Enhancing patient and healthcare personal education will hopefully overcome cultural and religious barriers to organ donation.

Abstract
Pediatric kidney transplantation is a multidisciplinary therapy that needs special consideration and experience. In this study, we aimed to present CUCH experience; over a 10-year period, as a specialized center of kidney transplantation in children. We studied 148 transplantations performed at a single center from 2009 to 2018. Pretransplant and follow-up data were collected and graft/patient survival rates were evaluated. A total of 48 patients developed at least one rejection episode during 688 patient-years of follow-up. Infections, recurrence of original disease, and malignancy were the most important encountered medical complications (20%, 2%, and 1.4%, respectively). One-year patient survival was 94.1%, while graft and patient survival was 91.9%. Graft/patient survival at 5, 7, and 9 years was 90%, 77%, and 58%, respectively. Infections were the main cause (69%) of mortality. Death with a functioning graft and CR were the main causes of graft loss (48% and 33%, respectively). Pediatric kidney transplantation in Egypt is still a challenging yet successful experience. Rejections and infections are the most frequent complications. Short-term outcomes surpass long-term ones and graft survival rates are similar to the international standard.

Abstract
OBJECTIVES To evaluate long-term outcomes and risk factors for graft loss in pediatric kidney transplantation over a 30-year period. METHODS We retrospectively assessed 400 consecutive kidney transplants carried out in 377 children during 1975-2009. Patients were stratified according to the immunosuppressive regimen (era 1: methylprednisolone and azathioprine; era 2: calcineurin inhibitor-based therapy, including methylprednisolone and azathioprine or mizoribine; era 3: basiliximab induction therapy, including calcineurin inhibitors, methylprednisolone and mycophenolate mofetil). RESULTS The median age and bodyweight at transplantation were 9.7 years and 20.6 kg, respectively. In total, 364 (91.0%) children received a living related donor transplantation. The acute rejection rate within 1 year post-transplant decreased significantly from 61.0% in era 1 to 14.5% in era 3 (P < 0.001). For transplant eras 1-3, 1-year graft survival was 81%, 93% and 95%; 5-year graft survival was 66%, 86% and 93%; and 10-year graft survival was 47%, 79% and 89%, respectively. The overall 5-, 10- and 20-year patient survival rates were 96%, 93% and 88%, respectively. A Cox multivariate analysis identified cold ischemia time (hazard ratio 1.385, 95% confidence interval 1.251-1.603), acute rejection (hazard ratio 1.682, 95% confidence interval 1.547-3.842), re-transplant (hazard ratio 2.680, 95% confidence interval 1.759-3.982) and donor type (hazard ratio 2.957, 95% confidence interval 1.754-4.691) as independent risk factors for graft loss at 10 years post-transplant. CONCLUSIONS The progress of immunosuppressive therapy has led to a low incidence of acute rejection and a high graft survival rate across 30 years of pediatric transplantation.

Abstract
Renal transplantation is the treatment of choice for ESRD in children. It is associated with better quality of life, growth of children, and improved long-term survival. The aim of the study was to evaluate the outcomes of pediatric renal transplantation at a tertiary care center in UAE. A retrospective chart review was undertaken for all the pediatric renal transplants performed at Sheikh Khalifa Medical City, Abu Dhabi, UAE, over the past 9 years. The study evaluated the demographic data, outcomes, and complications of pediatric renal transplantation. The post-transplantation outcomes including surgical complications, documented infections, graft rejection, graft and patient survival, effect on growth, and eGFR were reviewed. Between 2010 and 2018, 30 pediatric patients underwent renal transplantation. The follow-up period ranged from 1 to 9 years with a mean of 3.3 years. The mean age of the patients at the time of transplant was 9.8 years, and 56.7% were males. Prior to the transplantation, the majority of the recipients were on peritoneal dialysis (70.0%). Main source of renal donation at our center was from LRD, chiefly from parents. Patient survival at 1 and 5 years was 100% and 96.7%, respectively. Graft survival at 1 and 5 years was 96.7% and 83.3%, respectively. During the 9-year follow-up period, 5 (16.7%) recipients experienced rejection episode. This study demonstrates that during 5-year period, pediatric kidney transplantation program has achieved optimal patient (96.7%) and graft (83.3%) survival rates and is comparable to well-established centers.

Abstract
Over the past 30 years, there has been an improvement in both patient and graft survival after pediatric renal transplantation (RTX). Despite this success, these patients still carry an elevated risk for untimely death, partly through premature aging of the vasculature. The aim of this study was thus to investigate the long-term outcome of individuals with RTX in childhood, as well as to explore the cardiovascular health of these adults more than a decade later. We studied 131 individuals who had undergone a RTX between the years 1979 and 2005. Furthermore, left ventricular hypertrophy (LVH), coronary artery calcifications (CAC), and related metabolic factors were investigated in a cross-sectional study including 52 individuals as part of the initial cohort. The mortality rate (n = 131) was 12.2%. The median estimated graft survival was 17.5 years (95% CI 13.6-21.3), being significantly better in children transplanted below the age of 5 years (18.6 vs. 14.3 years, P < 0.01) compared with older ones. CAC were found in 9.8% and LVH in 13% of the patients. Those with cardiac calcifications had longer dialysis vintage and higher values of parathyroid hormone (PTH) during dialysis. Left ventricular mass correlated positively with systolic blood pressure, PTH, and phosphate measured at the time of the study.

Abstract
The Brazilian collaborative registry for pediatric renal transplantation began in 2004 as a multicenter initiative aimed at analyzing, reporting, and disseminating the results of pediatric renal transplantation in Brazil. Data from all pediatric renal transplants performed from January 2004 to May 2018 at the 13 participating centers were analyzed. A total of 2744 pediatric renal transplants were performed in the thirteen participating centers. The median age at transplantation was 12.2 years, with the majority being male recipients (56%). The main underlying diseases were CAKUT (40.5%) and glomerulopathy (28%). 1981 (72%) of the grafts were from deceased donors (DD). Graft survival at one year (censored by death) was 94% in the live donor group (LD) and 91% in the DD group (log-rank test P < 0.01). The patient's survival at one and 5 years was 97% and 95% for the LD group and 96% and 93% for the DD group (log-rank test P = 0.02). The graft loss rate was 19% (n = 517), more frequently caused by vascular thrombosis (n = 102) and chronic graft nephropathy (n = 90). DD recipients had 1.6 (1.0-2.2) times greater chance of death and 1.5 (1.2-1.8) times greater chance of graft loss compared to LD recipients. The mortality rate was 5.4% (n = 148), mainly due to infection (n = 69) and cardiovascular disease (n = 28). The results of this collaborative pediatric renal transplant record are comparable to other international registries, although we still have a high infection rate as a cause of death.

Abstract
OBJECTIVES Kidney transplant is the optimal treatment for children with end-stage renal disease. Multiple factors affect patient and graft survival. We assessed determinants of long-term patient/graft survival in our center by a retrospective review of pediatric living donor (< 18 years) kidney transplants from February 2003 to December 2016. MATERIALS AND METHODS Donor and recipient demo-graphic data and immunosuppression use were gathered for analyses. Transplant outcomes included patient/graft survival, acute rejection, and 1-year estimated glomerular filtration rate. Patient/graft survival results were analyzed by Kaplan-Meier, and Cox proportional hazards regression model was used for risk factors (univariate/multivariate). P ≤ .05 was statistically significant. RESULTS Ninety-nine patients were included. Age was 13.4 ± 3.08 years, 64.6% were male, and 88.9% were on dialysis with time of 17.1 ± 12.6 months. Mean donor age was 36.6 ± 7.7 years, and most were females (63.6%). Donor estimated glomerular filtration rate was 89.4 ± 16.9 mL/min/1.73 m2. HLA match was 3.2 ± 1.05. Panel reactive antibody showed 8.6 ± 20.5%. Of total patients, 47.5% used induction, 88.9% used cyclo-sporine, and 100% used mycophenolate mofetil. Five- and 10-year patient survival rates were 93.2% and 93.2%. One-year acute rejection was 14.1%, with rate of 24.2% throughout follow-up. One-year estimated glomerular filtration rate was 76.4 ± 25.6 mL/min/1.73 m2. Five- and 10-year graft survival rates were 62.6% and 43.3%. Multivariate analysis confirmed donor age and acute rejection episodes throughout follow-up as risk factors for graft survival (P < .05). CONCLUSIONS Acute rejection and donor age are important risk factors for 10-year graft survival in living-donor pediatric kidney transplant in our program.

Abstract
RTx remains challenging in children under 3 years of age. This single-center study reviewed the medical records of children <3 years transplanted since 1987 (N = 32, Group 1). They were matched for donor type and RTx period with children aged 3-13 years (N = 32, Group 2) and 13-18 years (N = 32, Group 3). There were no between-group significant differences regarding distributions of gender, primary renal disease, proportion of dialysis before RTx, and growth (SDS). Compared to Groups 2 and 3, Group 1 had more peritoneal dialyses (P < .001), more EBV mismatches (P = .04), and longer warm ischemia times (P < .001). The risk of graft loss was not significantly different among age groups (hazard ratio, 2.4 in Group 2 and 2.0 in Group 3 vs Group 1; P = .2). Death occurred in four patients (3 in Group 1 and 1 in Group 2) and graft loss occurred in 28 patients, mainly due to chronic allograft nephropathy. In recipients <3 years of age, the outcomes of RTx are close to those obtained in older pediatric age groups. Thus, young patients may be transplanted in experienced multidisciplinary teams without additional risks provided that particular attention is paid to donor selection and prevention/early diagnosis of comorbidities and complications.

Abstract
Pediatric kidney Tx has critically altered the outcome in ESRD pediatric patients. The aims of this study were to determine long-term graft and patient survival in a homogeneous ethnic population. We reviewed the medical charts of pediatric kidney Tx performed between 1990 and 2012 in Greece. Seventy-five kidney Txs were performed from LRD and 62 from DD. The 10- and 20-yr graft survival was higher in LRD Tx compared with DD Tx. Both patient and graft survival at 10 and 20 yr after Tx were similar in LRD Tx from grandparents compared with parents (92.9% vs. 93.4% 20-yr patient survival, 71.4% vs. 78.7% and 57.1% vs. 72.1%, 10- and 20-yr graft survival, respectively). However, there was a decreasing tendency in LRD Tx rates in period 2001-2012 compared with period 1990-2000 (47.1% vs. 62.7%). Risk factors for poor five-yr graft survival were DD Tx, and induction treatment with ALG compared with basiliximab, but their effect attenuated at 10 yr after Tx. In conclusion, Tx from LRD may offer efficient survival outcomes irrespective of donor age, suggesting that even older LRD could be an excellent option for the 1st kidney Tx in children and adolescents.

Abstract
Renal transplantation in paediatric patients usually provides excellent short-term and medium-term results. Early diagnosis of chronic kidney disease and active therapy of end-stage renal disease before and after transplantation enables the majority of children to grow and develop normally. The adverse effects of immunosuppressive medication and reduced graft function might, however, hamper long-term outcomes in these patients and can lead to metabolic complications, cardiovascular disease, reduced bone health, and malignancies. The neurocognitive development and quality of life of paediatric transplant recipients largely depend on the primary diagnosis and on graft function. Poor adherence to immunosuppression is an important risk factor for graft loss in adolescents, and controlled transition to adult care is of utmost importance to ensure a continued normal life. In this Review, we discuss the outcomes and long-term effects of renal transplantation in paediatric recipients, including consequences on growth, development, bone, metabolic, and cardiovascular disorders. We discuss the key problems in the care of paediatric renal transplant recipients and the remaining challenges that should be the focus of future research.

Abstract
The transfer of renal transplant patients from pediatric to adult care is a crucial step with a high risk of subsequent graft loss. Therefore, the transition should be a thoroughly planned, well-designed and multidisciplinary process focused on the individual patient. Our pediatric nephrology department introduced a structured step-by-step transition program supported by a multidisciplinary team of health professionals. The purpose of our study was to determine the effects of the transition program on eGFR and number of ARs in comparison to a group without a transition program at one and three yr after transfer. We conducted a single-center retrospective cohort study of renal transplant patients prior to and after the introduction of the transition program. Multiple regression analysis revealed a significantly lower decline of eGFR in the group with transition program (-11.3 ± 44 mL/min/1.73 m(2) ) compared to the group without transition program (-28.4 ± 33 mL/min/1.73 m(2) ) at three yr after transfer. The number of AR episodes significantly decreased from 34.6% in the group without transition program to 9.1% in the group with transition program. The standardized multilevel transition program seems to have significant positive effects on eGFR and number of AR episodes in renal transplant patients.

Abstract
BACKGROUND Kidney transplantation prior to dialysis (pre-emptive kidney transplantation, PKT) has been controversial because of the paucity of clinical evidence to clarify the risks and benefits of PKT. Several authors have confirmed a significant advantage of PKT in the treatment of patients with end-stage renal disease (ESRD). The aim of this study was to examine the characteristics of patients who received PKT or non-pre-emptive kidney transplant (NPKT). METHODS We used a cohort of 323 consecutive kidney-transplanted children (53% boys) from Hospital da Criança Santo Antonio, Porto Alegre, Brazil, who underwent transplantation between January 2000 and December 2010. RESULTS The main causes of ESRD were congenital anomalies of the kidney and urinary tract (CAKUT) (39%) and glomerulopathies (27.5%). The 12-, 36-, 60-, and 90-months death-censored graft survival rates were 97%, 92%, 86%, and 76%, respectively, in the PKT group, and 87%, 79%, 72%, and 65% in the NPKT group (P < .05). CONCLUSIONS The results of this study suggest that pre-emptive transplantation is beneficial (hazard ratio = 0.37; 95% confidence interval: 0.18-0.82). The main causes of graft loss (n = 67) were recurrence of primary disease (21%), chronic allograft injury (17%), and death with a functioning graft (16%). We recommend PKT as a better choice for transplantation whenever possible to minimize ESRD morbidity and provide better long-term patient and graft survival.
