Abstract
BACKGROUND Proper care of young children in need of kidney transplant (KT) requires many skilled professionals and an expensive hospital structure. Small children have lesser access to KT. METHODS We describe a strategy performed in Brazil to enable and accelerate KT in children ≤15 kg based on the establishment of one specialized transplant center, focused on small children, and cooperating with distant centers throughout the country. Actions on 3 fronts were implemented: (a) providing excellent medical assistance, (b) coordinating educational activities to disseminate expertise and establish a professional network, and (c) fostering research to promote scientific knowledge. We presented the number and outcomes of small children KT as a result of this strategy. RESULTS Three hundred forty-six pediatric KTs were performed in the specialized center from 2009 to 2017, being 130 in children ≤15 kg (38%, being 41 children ≤10 kg) and 216 in >15 kg (62%). Patient survival after 1 and 5 years of the transplant was 97% and 95% in the "small children" group, whereas, in the "heavier children" group, it was 99% and 96% (P = 0.923). Regarding graft survival, we observed in the "small children" group, 91% and 87%, whereas in the "heavier children" group, 94% and 87% (P = 0.873). These results are comparable to the literature data. Groups were similar in the incidence of reoperation, vascular thrombosis, posttransplant lymphoproliferative disease, and estimated glomerular filtration rate. CONCLUSIONS The strategy allowed an improvement in the number of KT in small children with excellent results. We believe this experience may be useful in other locations.

Abstract
Bone remodeling is a complex process which integrates different stimuli factors such as mechanical, nutritional and hormonal factors as well as cytokines and growth factors. Bone health depends on an adequate balance between all these factors. The typical bone pathology of the newborn is the metabolic bone disease of prematurity, favored by a lack of mineral accretion in the third trimester of gestation. The intrinsic defects of the bone tissue (primary osteoporosis) are usually of genetic or idiopathic origin and can affect both the term and the preterm newborn. Other risk factors for osteopenia (secondary osteoporosis) include maternal or gestational factors, nutritional deficits (calcium, phosphorus, vitamin D), endocrinological alterations, use of certain medications antagonistic to bone metabolism, mechanical factors and chronic diseases (renal or hepatic insufficiency, intestinal malabsorption, collagen or metabolic diseases). This review examines the risk factors of developing bone metabolic disorders in neonates.

Is Preoperative Preparation Time a Barrier to Small Children Being Ready for Kidney Transplantation? Transplantation 2019; 104:591-596.

Abstract
BACKGROUND Small children are less frequently transplanted when compared with older. The objective of the present study was to compare the preparation time for transplantation in children of different weights and to identify factors associated with a delay in the workup of small children. METHODS We report on a retrospective cohort comprising all children referred for renal transplantation (RTx) workup between 2009 and 2017. The main outcome was transplantation workup time, defined as the time elapsed between the first consultation and when the child became ready for the surgery. RESULTS A total of 389 children (63.5% males) were selected, with a median weight of 18 kg (interquartile range, 11-32). Patients were categorized into 2 groups: group A (study group): ≤15 kg (n = 165) and group B (control group): >15 kg (n = 224). The probability of being ready for RTx was comparable between groups A and B. The cumulative incidence rate difference between groups is -0.05 (95% confidence interval, -0.03 to 0.02). The median time for RTx workup was 5.4 (2.4-9.4) in group A and 4.3 (2.2-9.0) months in group B (P = 0.451). Moreover, the presence of urinary tract malformation was associated with the need for longer transplantation workup time (P < 0.001). CONCLUSIONS In children >7 kg, the workup time for transplantation is not related to body weight. In a specialized center, children weighing 7-15 kg became ready within the same timeframe as children weighing >15 kg, despite the smaller children had greater difficulty being nourished, dialyzed, and a greater need for surgical correction of the urinary tract pretransplant.

Abstract
CONTEXT Technological advances in fetal and neonatal medicine, recent changes in the French legal framework, and encouraging results of the long-term outcomes in children with neonatal renal failure provide elements for an ethical reflection. METHODS We led a nationwide enquiry among French pediatric nephrologists, intensivists, and neonatologists, exploring the decision-making process when contemplating starting renal replacement therapy (RRT) or delivering palliative care to neonates or infants with pre-end-stage or end-stage renal disease; and the ethical quandaries at hand in such scenarios. RESULTS A total of 134 responses with complete national coverage were obtained. Care to be delivered to an infant in pre-end-stage or end-stage renal disease did not achieve consensus. Pediatric nephrologists were more prone to initiate a dialysis/graft program than pediatric intensivists. When chronic kidney disease was associated with comorbidities, especially neurological impairment, physicians, regardless of their subspecialty, were more reluctant to initiate conservative treatment. Many of the doctors surveyed did not give their opinion in these prenatal and/or postnatal situations, considered to be unique and warranting a multidisciplinary reflection. CONCLUSION Such ethical dilemmas are challenging for parents and physicians. They can only be overcome by taking into account both concrete on the ground realities and general principles and values acknowledged to be a basis for respecting the individual. In this way, it ensures humaneness and humanization of a practice that must meet a variety of challenges, one by one. The answer is not simple; it is always unique to each child and can only be approached by a multidisciplinary, time-consuming, open discussion, which will never totally erase uncertainty.

Abstract
Recent advances in neonatal cardiorespiratory management and neonatal renal replacement therapy have led to occasional reports of favorable short-term and long-term outcomes for Potter sequence, once thought to be fatal. The present patient was a girl born at a gestational age of 34 weeks 4 days with a birthweight of 1398 g. She was diagnosed with Potter sequence complicated by pulmonary hypoplasia due to left renal agenesis and small right kidney. Hemodialysis was started because anuria persisted even after persistent pulmonary hypertension receded and cardiorespiratory status improved. Peritoneal dialysis during the clinical course failed to achieve stability because of pericatheter leakage and frequent obstruction of the peritoneal dialysis catheter; in the meantime, hemodialysis was also performed. Once bodyweight passed 3.5 kg, peritoneal dialysis became more feasible with stability; the patient was discharged at 9 months and at the time of writing was on peritoneal dialysis at home, and renal transplantation was planned.

Abstract
Renal transplantation (RTx) has become an accepted mode of therapy in infants with severe renal failure. The major indications are structural abnormalities of the urinary tract, congenital nephrotic syndrome, polycystic diseases, and neonatal kidney injury. Assessment of these infants needs expertise and time as well as active treatment before RTx to ensure optimal growth and development, and to avoid complications that could lead to permanent neurological defects. RTx can be performed already in infants weighing around 5 kg, but most operations occur in infants with a weight of 10 kg or more. Perioperative management focuses on adequate perfusion of the allograft and avoidance of thrombotic and other surgical complications. Important long-term issues include rejections, infections, graft function, growth, bone health, metabolic problems, neurocognitive development, adherence to medication, pubertal maturation, and quality of life. The overall outcome of infant RTx has dramatically improved, with long-term patient and graft survivals of over 90 and 80 %, respectively.

Sustaining life or prolonging dying? Appropriate choice of conservative care for children in end-stage renal disease: an ethical framework. Pediatr Nephrol 2015; 30:1761-9.

Abstract
Due to technological advances, an increasing number of infants and children are surviving with multi-organ system dysfunction, and some are reaching end-stage renal disease (ESRD). Many have quite limited life expectancies and may not be eligible for kidney transplantation but families request dialysis as alternative. In developed countries where resources are available there is often uncertainty by the medical team as to what should be done. After encountering several of these scenarios, we developed an ethical decision-making framework for the appropriate choice of conservative care or renal replacement therapy in infants and children with ESRD. The framework is a practical tool to help determine if the burdens of dialysis would outweigh the benefits for a particular patient and family. It is based on the four topics approach of medical considerations, quality-of-life determinants, patient and family preferences and contextual features tailored to pediatric ESRD. In this article we discuss the basis of the criteria, provide a practical framework to guide these difficult conversations, and illustrate use of the framework with a case example. While further research is needed, through this approach we hope to reduce the moral distress of care providers and staff as well as potential conflict with the family in these complex decision-making situations.

Evaluation of quality of life by young adult survivors of severe chronic kidney disease in infancy. Pediatr Nephrol 2014; 29:1387-93.

Abstract
BACKGROUND The health related quality of life (HRQoL) of young adults treated for chronic kidney disease (CKD) stage 4/5 from infancy is unknown. METHODS A HRQoL questionnaire was sent to all 41 patients aged >16 years from a previously characterised cohort of infants with CKD stage 4/5 born between 1986 and 1997. Patient scores were compared with a previously reported cohort of patients who needed renal replacement therapy (RRT) in mid childhood and in the normal population. RESULTS All patients (11 women) completed the questionnaire at a median (range) age of 19.2 (16.3-23.4) years. At the time of the survey, 5 (12.5 %) were on dialysis, 35 (85.5 %) had a functioning kidney transplant, one (2 %) was still conservatively treated and 22 (54 %) had comorbidities; 68 % were either studying or in paid employment, with 17 % actively seeking employment. Although patients described a lower HRQoL than a healthy, age-matched UK group, in some aspects, scores were comparable with patients needing RRT in later childhood. Lower scores were associated with comorbidities, dialysis at last follow-up, more than one treatment modality change and short stature. CONCLUSIONS Our survey demonstrates very encouraging results for long-term HRQoL of infants with severe CKD and highlights the negative impact of comorbidities. These data will help clinicians to counsel and inform families.

Abstract
BACKGROUND Young children with end-stage renal disease (ESRD) requiring renal replacement therapy (RRT) have traditionally experienced high rates of morbidity and mortality; however, detailed long-term follow-up data is limited. METHODS Using a population-based retrospective cohort with data from a national organ failure registry and administrative data from Canada's universal health care system, we analysed the outcomes of 87 children starting RRT (before age 2 years) and followed them until death or date of last contact [median follow-up 4.7 years, interquartile range (IQR) 1.4-9.8). We assessed secular trends in survival and the influence of: (1) age at start of RRT and (2) etiology of ESRD with survival and time to transplantation. RESULTS Patients were mostly male (69.0 %) with ESRD predominantly due to renal malformations (54.0 %). Peritoneal dialysis was the most common initial RRT (83.9 %). Fifty-seven (65.5 %) children received a renal transplant (median age at first transplant: 2.7 years, IQR 2.0-3.3). During 490 patient-years of follow-up, there were 23 (26.4 %) deaths, of which 22 occurred in patients who had not received a transplant. Mortality was greater for patients commencing dialysis between 1992 and 1999 and among the youngest children starting RRT (0-3 months). Children with ESRD secondary to renal malformations had better survival than those with ESRD due to other causes. Among the transplanted patients, all but one survived to the end of the observation period. CONCLUSION Children who start RRT before 3 months of age have a high risk of mortality. Among our paediatric patient cohort, mortality rates were much lower among children who had received a renal transplant.

Abstract
Estimates suggest that one third of United States health care spending results from overuse or misuse of tests, procedures, and therapies. The American Board of Internal Medicine Foundation, in partnership with Consumer Reports, initiated the "Choosing Wisely" campaign to identify areas in patient care and resource use most open to improvement. Nine subspecialty organizations joined the campaign; each organization identified five tests, procedures, or therapies that are overused, are misused, or could potentially lead to harm or unnecessary health care spending. Each of the American Society of Nephrology's (ASN's) 10 advisory groups submitted recommendations for inclusion. The ASN Quality and Patient Safety Task Force selected five recommendations based on relevance and importance to individuals with kidney disease.Recommendations selected were: (1) Do not perform routine cancer screening for dialysis patients with limited life expectancies without signs or symptoms; (2) do not administer erythropoiesis-stimulating agents to CKD patients with hemoglobin levels ≥10 g/dl without symptoms of anemia; (3) avoid nonsteroidal anti-inflammatory drugs in individuals with hypertension, heart failure, or CKD of all causes, including diabetes; (4) do not place peripherally inserted central catheters in stage 3-5 CKD patients without consulting nephrology; (5) do not initiate chronic dialysis without ensuring a shared decision-making process between patients, their families, and their physicians.These five recommendations and supporting evidence give providers information to facilitate prudent care decisions and empower patients to actively participate in critical, honest conversations about their care, potentially reducing unnecessary health care spending and preventing harm.

Abstract
BACKGROUND Renal oligohydramnion (ROH) is predominantly caused by congenital abnormalities of the kidney and urogenital tract (CAKUT). Although the number of neonates born with chronic renal failure is small, they provide many challenges, and among the most problematic are respiratory management and long-term treatment of chronic renal failure. We studied the value of prenatal and perinatal variables to predict survival and the general long-term outcome of our ROH population. Method. A single-centre retrospective chart review was conducted in 36 neonates with ROH treated between 1996 and 2007. Respiratory data sets including minimum inspiratory oxygen concentration (FiO(2), 1d), best oxygenation index (BOI, 1d) and minimum arterial partial carbon dioxide (pCO(2), 1d) at the first day of life were available in 23 children requiring intubation. RESULTS ROH causes were obstructive uropathy (n = 19), polycystic kidney disease [autosomal recessive polycystic kidney disease (ARPKD) n = 5 and autosomal dominant polycystic kidney disease n = 1], renal agenesis/dysplasia (n = 10) and bilateral renal vein thrombosis (n = 1). Survival until discharge was 64% (23/36), and overall survival was 58% (21/36). Seven patients died within 48 h from respiratory failure. Non-survivors had a higher minimum FiO(2) and pCO(2) (1d) compared to survivors (P < 0.001). Mean BOI (1d) was 6.2 in survivors versus 43.9 in the non-surviving group (P < 0.001). Logistic regression showed that BOI (</≥ 9.6) and first diagnosis of ROH (≤/>28 gestational weeks) retained significance in predicting survival until discharge. CONCLUSIONS The attitude toward initiating dialysis in neonates is changing and long-term outcome in the absence of severe comorbidity is promising. Prenatal prediction concerning respiratory and renal outcome in fetuses with ROH is difficult. Our data suggest that BOI (1d) and onset of ROH may be reliable predictors of respiratory prognosis in children born with ROH.

Abstract
PURPOSE OF REVIEW The term 'renal replacement therapy' has been employed for describing dialytic interventions for acute and chronic patients. The implications of this terminology do not correctly reflect the extent that we are able to address native renal function. Provision of correct terminology to describe dialytic therapies may provide insight and investigation into the 'nonreplaceable' aspects of renal function in the acute and chronic settings. RECENT FINDINGS The terms 'chronic kidney disease' and 'acute kidney injury' have replaced the terms chronic renal failure and acute renal failure, respectively. Changing terminology has improved definitions and clinical care in these patient groups. Improvements in dialytic therapies have not been paralleled by changes in our understanding of the native renal function components that are not replaced during dialysis. SUMMARY A paradigm shift in our understanding of replacement of renal function is necessary. The terminology of 'renal replacement therapy' should be supplanted by more appropriate terminology, 'renal supportive therapy'. The benefits of employing terminology that adequately reflects the extent to which we can offer supportive dialytic treatment to our acute and chronic patients may be realized as a significant stimulus for scientific investigation and clinical care improvements.

Abstract
BACKGROUND AND OBJECTIVES In 2000, we reported the outcome of 101 children with a GFR <20 ml/min per 1.73 m2 at 0.3 yr of age (range 0.0 to 1.5 yr). Long-term data on such young children are scarce. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Mortality, treatment modalities, and growth were reanalyzed 9.9 yr later. RESULTS Of the 101 patients, 28 died and three were lost to follow-up during 13.90 yr (range 0.03 to 22.90 yr). One-, 2-, 5-, 10-, 15-, 20-, and 22-yr survivals were 87, 81, 77, 75, 73, 72, and 64%, respectively. Fifty-one children had comorbidities. Sixty-six percent were tube fed for 1.7 yr (range 0.1 to 6.9 yr), 37% had a gastrostomy, and 13% had a Nissen fundoplication. Mean height SD score (SD) was -0.42 (2.33) at birth (n = 40), -2.07 (1.34) at 0.5 (n = 62), -1.93 (1.38) at 1 (n = 72), -1.14 (1.14) at 5 (n = 67), -1.04 (1.15) at 10 (n = 62), -1.84 (1.32) at 15 (n = 40), and -1.68 (1.52) at age > or =18 yr (n = 32). Comorbidities adversely influenced growth (P < 0.01) and final height (P = 0.02): Mean height SD score (SD) was -1.16 (1.38) in otherwise normal adults. CONCLUSIONS Growth and final height in infants with severe chronic kidney disease are influenced by comorbidity. Intensive feeding and early transplantation resulted in a mean adult height within the normal range in patients without comorbidities. Overall mortality is comparable to that of older children.

Abstract
OBJECTIVE To perform a retrospective analysis of the long-term outcome of infants with end-stage kidney disease (ESKD) treated at our center during the past 25 years. STUDY DESIGN The total cohort (n = 52) was divided into era 1 (1983-1995; n = 23) and era 2 (1996-2008; n = 29). Dialysis morbidity, transplantation, and long-term survival rates were assessed and compared between the 2 eras. RESULTS Average age at initiation of dialysis was 4.4 +/- 5.3 months (range, 0.5-18 months), with 96% begun on peritoneal dialysis. The predominant diagnoses were dysplasia/obstructive uropathy and autosomal recessive polycystic kidney disease. The overall survival rate is 46%, with current age of survivors ranging from 1.5 to 25 years. Mortality rates in the 2 eras were not significantly different. The predominant mortality occurred within the first year. Twenty-four patients received an initial renal transplant at 2.6 +/- 1.7 years of age. Six patients (25%) required a second renal allograft. Increased risk for mortality included African-American ethnicity, oligoanuria, autosomal recessive polycystic kidney disease, and co-morbid diagnoses. CONCLUSIONS Long-term survival is possible in infants with ESKD, although mortality and morbidity remain high. Technical innovations are needed to accommodate smaller infants undergoing dialysis. Early initiation of dialysis treatment is preferable because prognostic indicators remain poorly defined.

Abstract
Perinatal renal tract disease is the main cause of end-stage renal failure in children. The diagnosis also includes many disorders of lesser severity, which may cause morbidity, such as hypertension, in later life. There remain uncertainties in the accuracy of some fetal diagnoses, and the life-time outcomes of children born with renal tract disease, who survive the neonatal period, are not known. There is a need for prospective trials to establish the efficacy, if any, with regard to protection of long-term kidney function of existing 'therapies', such as prenatal surgical decompression and postnatal drugs, which might slow the progression of renal failure. Specific drugs, which may block the growth of renal cysts, are being tested in humans. Advances in genetics are uncovering specific mutations in some children with renal tract malformations, providing parent and carers with explanations for the occurrence of such diseases.
