[PMID: 37881745 PMCID: PMC10593302 DOI: 10.4103/ijn.ijn_37_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2022] [Revised: 06/05/2022] [Accepted: 06/22/2022] [Indexed: 10/27/2023] Open
Abstract
Introduction Survival of tunneled cuffed catheters (TCC), used widely in children, is complicated by infections and catheter dysfunction. In resource limited settings, where risk of complications could be higher and waiting period for transplantation longer, catheter survival determines patient survival. This study was conducted to determine infection free catheter survival rates, incidence of catheter failure and associated risk factors. Methods Children <18 years of age receiving maintenance hemodialysis through TCC at nephrology division of a pediatric hospital, over a period of 6 years. Data was collected with consecutive selection by a complete enumeration technique from pre-collected data sheets in the records. Exposure detected were catheter infections, thrombosis, and mechanical complications. Results Forty-five TCCs in 36 children studied for 12,590 catheter days showed catheter failure in 36%, due to catheter related infections in 75% and mechanical complications in 25%. The incidence of complications per 1000 catheter days was 1.19 infection, 1.03 thrombus, and 0.39 mechanical. Catheter-related blood stream infection (CRBSI) (15/36) was associated with thrombus in nine and led to mortality in three. The mean infection free catheter survival was 449 ± 42 days for cohort with 388 ± 38 days in Group A (premature catheter removal) and 593 ± 43 days in Group B (elective removal) (P = 0.03). Catheterization duration of 267 days predicted CRBSI (sensitivity 93%, specificity 66.7%) with area under the curve of 0.808. Conclusions Median infection free catheter survival was 449 days with catheter failure in 36%. CRBSI was the main cause of failure. Duration of catheterization greater than 267 days was a predictor of CRBSI.

Abstract
Specialized centers are needed for nephrology and urology care of children. The justifications are the specialized nature of care needed and the growing incidence and prevalence. Children with chronic kidney disease (CKD) are at risk of morbidity, mortality, and decreased quality of life. Current pediatric practice structures are apparently poorly suited for the increasing demands of chronic disease in children. Kidney diseases account for around 8%-10% of total outpatients and 12% of admissions to the pediatric ward in hospitals. The major causes of pediatric CKD in registries are congenital anomalies of the kidney and urinary tract (around 50%), followed by inherited nephropathies and glomerulonephritis. The nephrologist’s role is important for specialized investigations and treatment. Urologist’s services are essential for the wide variety of conditions from birth to early adult age for complete cure and complementing medical management. Children have a right to treatments and to resources that are as sophisticated and advanced as those available to adults. Simple and sophisticated care for all children with ailments of the kidneys and related structures is important for ensuring ‘health for all’. The availability of ‘Child Kidney Care Centers’ will go a long way in improving the lives of affected children.

Pais P, Wightman A. Addressing the Ethical Challenges of Providing Kidney Failure Care for Children: A Global Stance. Front Pediatr 2022; 10:842783. [PMID: 35359883 PMCID: PMC8963107 DOI: 10.3389/fped.2022.842783] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/24/2021] [Accepted: 02/10/2022] [Indexed: 01/10/2023] Open
Abstract
Children with kidney failure require kidney replacement therapy (KRT), namely maintenance dialysis and kidney transplant. Adequate kidney failure care consists of KRT or conservative treatment with palliative care. In the context of kidney failure, children depend on parents who are their surrogate decision-makers, and the pediatric nephrology team for taking decisions about KRT or conservative care. In this paper, we discuss the ethical challenges that arise relating to such decision-making, from a global perspective, using the framework of pediatric bioethics. While many ethical dilemmas in the care of children with KRT are universal, the most significant ethical dilemma is the inequitable access to KRT in low & middle income countries (LMICs) where rates of morbidity and mortality depend on the family's ability to pay. Children with kidney failure in LMICs have inadequate access to maintenance dialysis, timely kidney transplant and palliative care compared to their counterparts in high income countries. Using case vignettes, we highlight how these disparities place severe burdens on caregivers, resulting in difficult decision-making, and lead to moral distress among pediatric nephrologists. We conclude with key action points to change this status-quo, the most important being advocacy by the global pediatric nephrology community for better access to affordable kidney failure care for children.

Abstract
BACKGROUND Some pediatric patients on maintenance dialysis may need end-of-life care in the future because of being excluded from the indication of kidney transplantation and experiencing difficulty in continuation of their dialysis. This study aimed to thoroughly elucidate mortality outcomes of children on maintenance dialysis including the cause of death and clinical background of exclusion from indication of transplantation. PATIENTS AND METHODS This single-center retrospective study enrolled 53 children who received kidney transplantation (5) or maintenance peritoneal dialysis (PD, 48) as initial renal replacement therapy (RRT). We examined the selected RRT modalities, mortality outcomes, clinical backgrounds of cause of death, and risk factors of excluding from future the indication of transplantation. RESULTS Nine (17%) of all 53 patients, all receiving PD (9/48, 19%), were finally excluded from next RRT indication-7 were excluded due to severe extrarenal complications that indicated high risk for transplantation and 2 were excluded due to severe psychomotor retardation and at the guardians' discretion. Patients who were excluded from the indication had a younger age at PD induction and higher proportion of cerebral and cardiac complications or psychomotor retardation than patients who were included in the indication. Of the nine patients, seven died; of which, one patient died due to fatal progression of extrarenal complications and six died due to infectious or noninfectious dialysis-related complications. CONCLUSION Patients with severe extrarenal complications or psychomotor retardation tend to be excluded from the indication of transplantation. Their condition becomes fatal because of the complications of long-term dialysis and progression in extrarenal complications.

Abstract
Major advances have been made in the management of children with chronic kidney disease over the past 30 years. However, existing epidemiology data are primarily from kidney replacement therapy registries, and information available at earlier stages of chronic kidney disease is limited. The incidence and prevalence of chronic kidney disease stages 2 to 5 remain poorly understood. However, rare population-based studies suggest that the prevalence of all-stage chronic kidney disease may be as high as 1% of the pediatric population. Congenital disorders including congenital abnormalities of the kidney and urinary tract and hereditary nephropathies account for one-half to two-thirds of pediatric chronic kidney disease cases in middle and high-income countries, whereas acquired nephropathies seem to predominate in low-income countries. The progression of chronic kidney disease is slower in children with congenital disorders than in those with acquired nephropathy, particularly glomerular disease, resulting in a lower proportion of congenital abnormalities of the kidney and urinary tract as a cause of end-stage kidney disease compared to less advanced stages of chronic kidney disease. The incidence of kidney replacement therapy in the pediatric population ranged by country from 1 to 14 per million children of the same age in 2018 (approximately 8 per million children in France) in patients younger than 20 years. The prevalence of kidney replacement therapy in children under 20 years of age in 2018 ranged from 15-30 per million children in some Eastern European and Latin American countries to 100 per million children in Finland and the United States (56 per million children in France). Most children with end-stage kidney disease initiate kidney replacement therapy with dialysis (more frequently hemodialysis than peritoneal dialysis). In about 20% of cases, the initial kidney replacement therapy modality is a pre-emptive kidney transplantation. In high-income countries, 60-80% of prevalent children with end-stage kidney disease live with a functioning transplant (75% in France). While the survival of children with chronic kidney disease has continuously improved over time, mortality remains about 30 times higher than in the general pediatric population.

Abstract
Pediatric nephrology has a history rooted in pediatric advocacy and has made numerous contributions to child health policy affecting pediatric kidney diseases. Despite this progress, profound social disparities remain for marginalized and socially vulnerable children with kidney disease. Different risk factors, such as genetic predisposition, environmental factors, social risk factors, or health care access influence the emergence and progression of pediatric kidney disease, as well as access to life-saving interventions, leading to disparate outcomes. This review will summarize the breadth of literature on social determinants of health in children with kidney disease worldwide and highlight policy-based initiatives that mitigate the adverse social factors to generate greater equity in pediatric kidney disease.

Abstract
Aim: To Identify association between risk factors to Chronic kidney disease (CKD) stage 5 in children with glomerular diseases in children in China. Methods: The Hospital Quality Monitoring System database was used to extract data for the study cohort. The primary outcome included progression to CKD stage 5 or dialysis. Cox regression was used to assess potential risk factors. Patients with lower stages (CKD stage 1 and 2) and higher stages (CKD stage 3 and 4) at baseline were analyzed separately. Results: Of 819 patients (4,089 hospitalization records), 172 (21.0%) patients reached the primary outcome during a median followed-up of 11.4 months. In the lower stages group, factors associated with the primary outcome included older age [Hazard Ratio (HR), 1.21; 95% confidence interval (CI), 1.10-1.34] and out-of-pocket payment (HR, 4.14; 95% CI, 1.57-10.95). In the higher stages group, factors associated with the primary outcome included CKD stage 4 (HR, 2.31; 95% CI, 1.48-3.62) and hypertension (HR, 1.99; 95% CI, 1.29-3.07). The medical migration rate was 38.2% in this study population. Conclusion: There are different risk factors for progression to the primary outcome in different stages in CKD with glomerular etiology. Further prospective studies are needed to assess these risk factors. The high medical migration rate reflected the regional disparities in the accessibility of pediatric kidney care between regions.

Abstract
BACKGROUND When detected early, inexpensive measures can slow chronic kidney disease progression to kidney failure which, for children, confers significant morbidity and impacts growth and development. Our objective was to determine the incidence of late presentation of childhood chronic kidney disease and its associated risk factors. METHODS We searched MEDLINE, Embase, PubMed, Web of Science, Cochrane Library and CINAHL, grey literature and registry websites for observational data describing children <21 years presenting to nephrology services, with reference to late presentation (or synonyms thereof). Independent second review of eligibility, data extraction, and risk of bias was undertaken. Meta-analysis was used to generate pooled proportions for late presentation by definition and investigate risk factors. Meta-regression was undertaken to explore heterogeneity. RESULTS Forty-five sources containing data from 30 countries were included, comprising 19,339 children. Most studies (37, n = 15,772) described children first presenting in kidney failure as a proportion of the chronic kidney disease population (mean proportion 0.43, 95% CI 0.34-0.54). Using this definition, the median incidence was 2.1 (IQR 0.9-3.9) per million age-related population. Risk associations included non-congenital disease and older age. Studies of hospitalised patients, or from low- or middle-income countries, that had older study populations than high-income countries, had higher proportions of late presentation. CONCLUSIONS Late presentation is a global problem among children with chronic kidney disease, with higher proportions seen in studies of hospitalised children or from low/middle-income countries. Children presenting late are older and more likely to have non-congenital kidney disease than timely presenting children. A consensus definition is important to further our understanding and local populations should identify modifiable barriers beyond age and disease to improve access to care.

Abstract
OBJECTIVES To study the etiology and clinical profile of congenital obstructive uropathy in children, renal status and growth at diagnosis and at follow-up and to determine the predictors for development of chronic kidney disease (CKD). METHODS An observational (retrospective-prospective) study was conducted at a tertiary care hospital in South India from September 2014 through September 2016. Sixty children diagnosed to have congenital obstructive uropathy with a minimum follow-up period of 5 y were included and followed up prospectively for 2 more years during the study period. The data of the children at admission and follow-up was obtained from the medical records and analyzed. RESULTS Congenital uretero-pelvic junction obstruction followed by Posterior urethral valve were the most common etiologies identified. Male preponderance (88.3%) was observed with poor urinary stream being the most common presentation (36.6%). Forty percent of the population had elevated creatinine. Fifteen percent were hypertensive and 25% had growth failure at diagnosis. However, there was a reduction in the number of children with poor estimated glomerular filtration rate (eGFR), hypertension and growth faltering during follow-up. Among the risk factors, hypertension at diagnosis [O.R-12.8 (2.21-74.22) and p value <0.05] and frequent urinary tract infection (UTI) [O.R-14.06 (2.32-85.42) and p value <0.05] were the most important factors for CKD progression. Children with low eGFR (< 60 ml/min/1.73m2) had more height faltering and hypertension at follow-up (p value <0.05). CONCLUSIONS Hypertension and frequent UTI were observed to be strongly associated with progression of CKD. Estimated GFR was found to be significantly associated with faltering of height and hypertension. Preserving the renal function prevents growth faltering and development of hypertension at follow-up thereby ensuring a better quality of life.

Abstract
This study aimed to determine the causes of chronic kidney disease (CKD) in Iranian children. In this systematic review and meta-analysis study, international (PubMed, Web of Science, Scopus, and Google Scholar) and national (SID, Magiran) databases were searched for articles published through December 30, 2017. The quality of the studies was determined using the Hoy instrument. Out of 2,117 initial studies, 13 studies performed on a total of 3,596 children were included in the final stage of the study. Based on the results of the random effects method (95% CI), the main causes of chronic kidney disease in stages 1–4 (CKD) were CAKUT (37%) and glomerulonephritis (19.96%); in stage 5 (ESRD) they were CAKUT (40.82%) and urological disorders (27.44%). Considering the high prevalence of CAKUT, glomerulonephritis and urinary problems, the use of comprehensive approaches can be very effective in enhancing the knowledge of patients about the causes of kidney disease. The results obtained from the present study can assist policymakers in more accurately planning screenings of the causes of CKD in Iranian children.

Abstract
AIM We report findings from a large single centre paediatric renal biopsy cohort in South Asia. METHODS We analyzed all renal biopsies performed on children aged ≤18 years between 1996 and 2015 at our centre. The clinical characteristics and histological diagnosis pertaining to each case, distribution of renal diseases in children with various clinical presentations, and changes in the pattern of kidney disease during the study period were analyzed. RESULTS A total of 1740 paediatric kidney biopsies were performed during the study period. The mean age was 12.8 ± 4.9 years (8 months to 18 years) and the male: female ratio was 1.5:1. The most common indication for renal biopsy was nephrotic syndrome (63.2%) followed by acute nephritic syndrome (13%). Minimal change disease was the most common cause of nephrotic syndrome while endocapillary proliferative glomerulonephritis (65.7% infection related), remained the commonest cause of acute nephritic syndrome. IgA nephropathy was the commonest cause of chronic kidney disease. Contrary to trends in European paediatric cohorts, the frequency of lupus nephritis increased over the two decades of the study, while that of endocapillary proliferative glomerulonephritis did not show any appreciable decline. CONCLUSION This study provides the largest data on biopsy proven renal disease in children from South Asia published till date and highlights important differences in the spectrum and trends of kidney disease compared to data from other regions.

Abstract
BACKGROUND AND OBJECTIVES High-quality epidemiologic data on the spectrum of biopsy-proven glomerular diseases among children are limited. This study aimed to determine the profile of and temporal change in biopsy-proven pediatric glomerular diseases in China. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS We previously conducted a nationwide kidney biopsy survey including 71,151 patients over an 11-year period from January 2004 to December 2014. A total of 7962 children younger than 18 years old from 115 hospitals across China with biopsy-proven glomerular diseases were included in this study. The demographic and clinical variables were extracted from referral records and pathology reports. The composition of pediatric glomerular diseases and clinicopathologic correlations in different sexes, age groups, and regions were assessed. The changing patterns of common glomerulopathies over the study period were examined. RESULTS Nephrotic syndrome (50%) was the most frequent indication for kidney biopsy in children. Minimal change disease was the most common primary glomerular disease (29%) followed by IgA nephropathy (17%). Henoch-Schonlein purpura nephritis (13%) and lupus nephritis (9%) were the most common secondary glomerular diseases. The proportion of minimal change disease was significant higher in boys (38%) than in girls (13%), whereas lupus nephritis was more prevalent in girls (20%) than in boys (3%). Purpura nephritis (23%) was the major pathologic pattern in younger children (0-12 years old), whereas minimal change disease (33%) was the most common glomerulopathy in adolescents (13-18 years old). The clinicopathologic correlations were slightly different between sexes and age groups. We observed increases in the proportions of minimal change disease, purpura nephritis, and membranous nephropathy over the study period that were contemporaneous with a fall in the proportion of FSGS. CONCLUSIONS The spectrum of glomerular diseases among children varied across sexes, age groups, and regions and changed substantially from 2004 to 2014 in China.

Abstract
Survival in the pediatric end-stage renal disease (ESRD) population has improved substantially over recent decades. Nonetheless, mortality remains at least 30 times higher than that of healthy peers. Patient survival is multifactorial and dependent on various patient and treatment characteristics and degree of economic welfare of the country in which a patient is treated. In this educational review, we aim to delineate current evidence regarding mortality risk in the pediatric ESRD population and provide pediatric nephrologists with up-to-date information required to counsel affected families.

Abstract
Background Pediatric nephrology is challenging in developing countries and data on the burden of kidney disease in children is difficult to estimate due to absence of renal registries. We aimed to describe the epidemiology and outcomes of children with renal failure in Cameroon. Methods We retrospectively reviewed 103 medical records of children from 0 to 17 years with renal failure admitted in the Pediatric ward of the Douala General Hospital from 2004 to 2013. Renal failure referred to either acute kidney injury (AKI) or Stage 3–5 chronic kidney disease (CKD). AKI was defined and graded using either the modified RIFLE criteria or the Pediatrics RIFLE criteria, while CKD was graded using the KDIGO criteria. Outcomes of interest were need and access to dialysis and in-hospital mortality. For patients with AKI renal recovery was evaluated at 3 months. Results Median age was 84 months (1QR:15–144) with 62.1% males. Frequent clinical symptoms were asthenia, anorexia, 68.8% of participants had anuria. AKI accounted for 84.5% (n = 87) and CKD for 15.5% (n = 16). Chronic glomerulonephritis (9/16) and urologic malformations (7/16) were the causes of CKD and 81.3% were at stage 5. In the AKI subgroup, 86.2% were in stage F, with acute tubular necrosis (n = 50) and pre-renal AKI (n = 31) being the most frequent mechanisms. Sepsis, severe malaria, hypovolemia and herbal concoction were the main etiologies. Eight of 14 (57%) patients with CKD, and 27 of 40 (67.5%) with AKI who required dialysis, accessed it. In-hospital mortality was 50.7% for AKI and 50% for CKD. Of the 25 patients in the AKI group with available data at 3 months, renal recovery was complete in 22, partial in one and 2 were dialysis dependent. Factors associated to mortality were young age (p = 0.001), presence of a coma (p = 0.021), use of herbal concoction (p = 0.024) and acute pulmonary edema (p = 0.011). Conclusion Renal failure is severe and carries a high mortality in hospitalized children in Cameroon. Limited access to dialysis and lack of specialized paediatric nephrology services may explain this dismal picture.

Abstract
OBJECTIVES To study the etiology and burden of comorbidities across stages of chronic kidney disease (CKD). METHODS Children, 2-16 y of age with CKD Stages II- IV were recruited over 12 mo. The etiology, clinical presentation and severity of complications were studied. RESULTS Among 78 children [Stage II (n = 21), Stage III (n = 26), Stage IV (n = 31)], congenital anomalies of the kidney and urinary tract (CAKUT) was the commonest etiology and 28 were newly diagnosed in Stage III /IV. High prevalence of comorbidities was observed with growth retardation (65%), hypertension (59%), hyperphosphatemia (32%), vitamin D deficiency (92%), dyslipidemia (64%), left ventricular hypertrophy (45%) and hyperparathyroidism (56%). While most comorbidities correlated with the estimated glomerular filtration rate and severity of CKD, hypertension, vitamin D deficiency and cardiovascular morbidity were prevalent even in early stages. CONCLUSIONS CAKUT was the commonest cause of CKD. Late detection and high prevalence of comorbidities even in early stages of CKD were observed.

Abstract
Background arginine and its metabolites have been linked to pediatric chronic kidney disease (CKD). We aimed to estimate serum levels of argninine (Arg), asymmetric dimethylarginine (ADMA) and symmetric dimethylarginine (SDMA) in pediatric CKD patients and its relation to altered kidney function. Patients and methods 132 pediatric patients with CKD and 120 healthy age and sex matched controls were compared regarding; serum Arg, ADMA and SDMA levels. Results In comparison to their values in control subjects, serum Arg levels were significantly lower; serum ADMA levels were non-significantly higher, but serum SDMA levels were significantly higher in CKD patients (p values: < 0.000; = 0.054; <0.000, respectively). Calculated Arg/ADMA and Arg/SDMA ratios were significantly higher in patients compared to controls (p values: 0.001, and <0.000, respectively). However ADMA/SDMA ratio was significantly lower in patients compared to controls (p = 0.001. Serum Arg levels showed positive significant correlation, while serum ADMA and SDMA levels showed negative significant correlation with eGFR. Moreover, Arg/ADMA ratio showed negative significant correlation, while ADMA/SDMA ratio showed positive significant correlation with eGFR of patients. Regression analysis defined high serum SDMA level as persistently significant predictor for low eGFR. Conclusion Disturbed serum levels of arginine and its dimethyl derivatives may underlie development and/or progression of CKD. Elevated serum SDMA level is strongly correlated with impaired kidney functions and could be considered as a predictor for kidney functions deterioration and CKD progression. The underlying pathogenic mechanisms for pediatric CKD are multiple and interlocking. Disturbed serum levels of Arg and its dimethyl derivatives may underlie development and/or progression of CKD. Elevated serum SDMA level is strongly correlated with impaired kidney functions. Elevated SDMA level can be a predictor for kidney functions deterioration and CKD progression.

Abstract
Background: It is well established that improvement of endothelial dysfunction (ED) could prevent or delay the occurrence of cardiovascular disease (CVD) and its related morbidity and mortality in patients with chronic kidney disease (CKD). In this study we investigated whether administration of vitamin C could be effective by improving brachial artery flow-mediated dilation (FMD) and intima media thickness (IMT), two surrogate markers of ED, in children with CKD or chronic renal failure (CRF). Materials and Methods: In this analytic-experimental study children aged 3-18 years with a diagnosis of CRF and a group of healthy children were enrolled. Vitamin C (250 mg/day) administrated for the two studied groups for 1 month. Endothelial function was evaluated by FMD and IMT measurement using vascular Doppler ultrasonography, before and after trial. Results: In this study 18 patients with CRF and 19 normal children as the control group were studied. At baseline mean of IMT and FMD was not different in the two studied groups (P > 0.05). After vitamin C administration IMT decreased significantly in the two studied groups (P < 0.05). FMD increased in the two studied groups but the difference was significant in the control group (P < 0.05). Conclusion: The findings of this interventional trial have demonstrated that vitamin C could have protective effect on ED of patients with CRF possibly in those with severe form of the disease but for obtaining more conclusive results larger sample size is needed.

Abstract
PURPOSE The aim of this study was to analyze the results of children treated with hemodialysis (HD) at Severance Hospital over 35 years in terms of incidence, etiologies, characteristics, complications, and clinical outcomes. MATERIALS AND METHODS We analyzed 46 children admitted to Severance Hospital who had undergone HD between January 1979 and December 2013. RESULTS The main etiologies of the 23 end-stage renal disease (ESRD) patients who had received HD were chronic glomerulonephritis (7 patients, 30.4%) and congenital anomalies of the kidney and urinary tract (7 patients, 30.4%), whereas the etiology of the 23 acute kidney injury (AKI) patients was hemolytic uremic syndrome (6 patients, 26.1%). Compared with ESRD patients, hemocatheter placement in the femoral vein was preferred over the subclavian or internal jugular vein in the AKI patients (p=0.012). The most common complication was catheter related complication (10 patients, 21.7%). The site of hemocatheter insertion was not related to the frequency of oozing. Placing the hemocatheter in the femoral vein resulted in significantly more events of catheter obstruction than insertion in the internal jugular vein or the subclavian vein (p=0.001). Disequilibrium syndrome occurred more frequently in older patients (p=0.004), as well as patients with a greater body weight (p=0.008) and a higher systolic and diastolic blood pressure before HD (systolic: p=0.021; diastolic: p=0.040). CONCLUSION Based on the 35 years of experience in our center, HD can be sufficiently and safely carried out even in children without significant complications.

Abstract
Hemodialysis is the most used renal replacement therapy for children in Morocco. The objective of this study was to determine the prevalence of patients who started hemodialysis in childhood and study their characteristics and specificities of their care. For this we conducted a multicentric descriptive cross-sectional study of all chronic hemodialysis patients who started dialysis in pediatric age, in hemodialysis centers in four of the sixteen regions of Morocco. We collected 2066 patients undergoing dialysis in 39 hemodialysis centers; from these, only 72 patients (3.48%) started hemodialysis in childhood. The average age of patients was 20.64 ± 6.5 years with a sex ratio of 1.9. Duration of dialysis was 78.2 ± 56 months. The cause of end stage renal disease was urological abnormalities in 18% of cases and glomerulopathy in 12.5% of cases; however, it remains unknown in half of the patients. Over 18 years, 74% of patients are without profession, it is active in 13% of cases, and pursuing studies are only in 13% of cases. Patients under 5 years and those with a low weight are rarely taken care of in chronic hemodialysis with little individualization of prescription. Greater attention should be paid to renal transplantation that is desired by the majority of these patients (92%).

Abstract
Background Children and adolescents with end-stage renal disease (ESRD) in sub-Saharan Africa may have the worst outcomes globally. Barriers to management include late presentation, poor socioeconomic conditions, absence of medical insurance, limited diagnostic facilities and non-availability of chronic renal replacement therapy (RRT). Our study was to determine the incidence, aetiology, management and outcomes of paediatric ESRD in a tertiary hospital in Nigeria. Methods A retrospective case review of paediatric ESRD at the University College Hospital Ibadan, Nigeria, over 8 years, from January 2005 to December 2012. Results 53 patients (56.6% male), median age 11 (inter quartile range 8.5-12) years were studied. Mean annual incidence of ESRD in Ibadan for children aged 14 years and below was 4 per million age related population (PMARP) while for those aged 5-14 years it was 6.0 PMARP. Glomerulonephritis was the cause in 41 (77.4%) patients amongst whom, 29 had chronic glomerulonephritis and 12 had nephrotic syndrome. Congenital anomalies of the kidneys and urinary tract (CAKUT) accounted for 11 (21.2%) cases, posterior urethral valves being the most common. Acute haemodialysis, acute peritoneal dialysis or a combination of these were performed in 33 (62.3%), 6 (11.3%) and 4 (7.5%) patients respectively. Median survival was 47 days and in-hospital mortality was 59%. Conclusions Incidence of paediatric ESRD in Ibadan is higher than previous reports from sub-Saharan Africa. Glomerulonephritis, and then CAKUT are the most common causes. Mortality is high, primarily due to lack of resources. Preventive nephrology and chronic RRT programmes are urgently needed.

Abstract
The prevalence of pediatric RRT and transplantation are low in developing countries, 6-12 and <1 to 5 per million child population (pmcp), respectively. This is due to low GDP/capita of <$10 000, government expenditure on health of <2.6-9% of GDP and paucity of facilities. The reported incidence of pediatric CKD and ESRD is <1.0-8 and 3.4-35 pmcp, respectively. RRT and transplantation are offered mostly in private centers in cities where HD costs $20-100/session and transplants $10 000-20 000. High costs and long distance to centers results in treatment refusal in up to 35% of the cases. In this backdrop 75-85% of children with ESRD are disfranchised from RRT and transplantation. Our center initiated an integrated dialysis-transplant program funded by a community-government partnership where RRT and transplantation was provided "free of cost" with life long follow-up and medication. Access to free RRT at doorsteps and transplantation lead to societal acceptance of transplantation as the therapy of choice for ESRD. This enabled us to perform 475 pediatric transplants in 25 years with 1- and 5-year graft survival of 96% and 81%, respectively. Our model shows that pediatric transplantation is possible in developing countries when freely available and accessible to all who need it in the public sector.

Abstract
Outcome of end-stage renal disease (ESRD) in children has considerably improved since the development of dialysis and kidney transplantation. This study was conducted to evaluate the management and outcome of ESRD children in a referral pediatric center in northwest Iran. A cross-sectional study of medical records of ESRD children (glomerular filtration rate less than 15 ml/min/1.73 m(2)) younger than 16 years who were admitted in Children's Hospital of Tabriz between October 1999 and October 2009 was performed. Ninety-four children with ESRD including 51 boys (54.3%) and 43 girls (45.7%) with a mean age of 7.9 ± 3.49 years were studied. Parents of nine patients (7.8%) refused treatment. Eighty patients underwent renal replacement therapy (RRT) and were followed for a mean period of 4.86 ± 2.77 years. Initial modality of RRT was hemodialysis in 81.25%, continuous ambulatory peritoneal dialysis in 16.25%, and preemptive kidney transplantation in 2.5%. Thirty-two patients (34%) underwent renal transplantation. The mean duration of staying on dialysis before transplantation was 12.4 ± 11 months. Twenty-nine of kidney donors (90.6%) were living unrelated donors. The 1-and 3-year graft survival rates were 81.2% and 68.8% and the 1- and 3-year patient survival rates were 96.9% and 93.8%, respectively. Thirty-one patients died (33%). The mortality of girls was significantly higher than boys (P=0.04). There was a significant negative correlation between age and mortality (P=0.01). Heart failure and infections were the most common cause of death. This study showed that ESRD children in our area have a poor outcome in comparison with developed countries.

Abstract
In the past 30 years there have been major improvements in the care of children with chronic kidney disease (CKD). However, most of the available epidemiological data stem from end-stage renal disease (ESRD) registries and information on the earlier stages of pediatric CKD is still limited. The median reported incidence of renal replacement therapy (RRT) in children aged 0-19 years across the world in 2008 was 9 (range: 4-18) [corrected] per million of the age-related population). [corrected] The prevalence of RRT in 2008 ranged from 18 to 100 per million of the age-related population. Congenital disorders, including congenital anomalies of the kidney and urinary tract (CAKUT) and hereditary nephropathies, are responsible for about two thirds of all cases of CKD in developed countries, while acquired causes predominate in developing countries. Children with congenital disorders experience a slower progression of CKD than those with glomerulonephritis, resulting in a lower proportion of CAKUT in the ESRD population compared with less advanced stages of CKD. Most children with ESRD start on dialysis and then receive a transplant. While the survival rate of children with ERSD has improved, it remains about 30 times lower than that of healthy peers. Children now mainly die of cardiovascular causes and infection rather than from renal failure.

Abstract
BACKGROUND The epidemiological information from well-defined populations regarding childhood chronic kidney disease (CKD), particularly those concerning non-terminal stages, are scanty. The epidemiology of CKD in children is often based on renal replacement therapy (RRT) data, which means that a considerable number of children in earlier stages of CKD are missed as they will reach end-stage renal disease (ESRD) in adulthood. Here, we report the basic epidemiological data on childhood CKD in Serbia, gathered over the 10-year period of activity of the Serbian Pediatric Registry of Chronic Kidney Disease. METHODS Since 2000-09, data on incidence, prevalence, aetiology, treatment modalities and outcome of children aged 0-18 years, with CKD Stages 2-4 and CKD Stage 5, were collected by reporting index cases from paediatric centres. RESULTS Three hundred and thirty-six children were registered (211 boys, 125 girls, male/female ratio 1.7). The median age at registration was 9.0 years [interquartile range (IQR) 3-13]. Median follow-up was 4.0 years (IQR, 1-9). The median glomerular filtration rate (GFR) at the time of the registration was 39.6 mL/min/1.73m(2) (IQR, 13.8-65.4). Median annual incidence of CKD 2-5 stages was 14.3 per million age-related population (p.m.a.r.p.), while those of CKD 2-4 or CKD 5 were 9.1 and 5.7 p.m.a.r.p., respectively. The median prevalence of CKD 2-5 was 96.1 p.m.a.r.p., 52.8 p.m.a.r.p. in CKD 2-4 and 62.2 p.m.a.r.p. in CKD 5. The main causes of CKD were congenital anomalies of kidney and urinary tract and hereditary nephropathies. Kidney survival was the worst in children with glomerular diseases and in those with advanced CKD. Haemodialysis was the most common first modality of RRT. Mortality rate was 4.5%, mainly due to cardiovascular and infectious complications. CONCLUSIONS Epidemiology of paediatric CKD in Serbia is similar to that reported from developed European countries. The knowledge of the epidemiology of earlier stages of CKD is essential for both institution of renoprotective therapy and planning of RRT, a fact of paramount importance in countries with limited resources.

Cephalometric craniofacial features of growing patients with chronic renal failure. Arch Oral Biol 2011; 57:257-63. [PMID: 22000306 DOI: 10.1016/j.archoralbio.2011.09.010] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2011] [Revised: 09/08/2011] [Accepted: 09/21/2011] [Indexed: 11/21/2022]
Abstract
INTRODUCTION Chronic renal failure (CRF) in growing children can affect their physical growth status. The objective of this research was to study the craniofacial morphology of children with CRF as evaluated by cephalometric analysis. METHODS Twenty-three growing children with CRF were included in this study. They were divided into three groups according to age ranges. The age ranges were >5-11 (group 1); >11-14 (group 2); >14-16 (group 3). Another twenty-three matching controls (in age and gender) were also included. Lateral cephalometric radiographs were taken as part of these children's orthodontic records. Lateral cephalometric radiographs were corrected for magnification distortion, digitized, and cephalometric analysis was performed. Data were analysed using ANOVA test. RESULTS The results showed that CRF patients in all age groups have statistically significantly decreased posterior cranial base lengths. Posterior facial heights showed a significant decrease in CRF patients in groups 1 and 2. Younger CRF patients (group 1) showed statistically significant increased gonial angle and FH-Mandibular plane angle, SN-Mandibular plane angle and decreased posterior to anterior face height ratio, total anterior facial height (N-Me), Mandibular body length (Go-Me), upper anterior facial height (N-ANS), Y axis length, pterygomaxillary-A point length. CONCLUSION Younger children (groups 1 and 2) with CRF showed a decrease in posterior facial growth (posterior facial height and posterior cranial base) when compared to matching normal controls. This decrease is not significant in older group (group 3). This finding suggests that children with CRF might catch up in growth with normal subjects and most of the earlier retarded growth features disappear with age.

Abstract
AIM The goal of this descriptive study was to evaluate the aetiology and the socioeconomic status in hospitalized children in Hanoi and propose solutions to improve prevention and basic health care of patients with chronic kidney disease in Hanoi City. METHODS The records of all 152 hospitalized children with chronic kidney disease in the National Paediatric Hospital in Hanoi from January 2001 to December 2005 were analyzed. RESULTS The incidence of paediatric chronic kidney disease native to Hanoi City was estimated to be 5.1/million-child population (pmcp). Median age was 11.29 years; 60.5% were boys and 39.5% were girls; 65% of patients were in end-stage renal disease. Causes of chronic kidney disease included glomerulonephritis (66.4%) and congenital/hereditary anomalies (13%). In 19.8% of children, the aetiology was unavailable. During hospitalization, five patients died and 76 patients (50%) refused the treatment although beneficiaries of health insurance. Thirty patients (19.74%) received peritoneal dialysis and haemodialysis, and seven patients received renal transplantation with a familial living donor. CONCLUSION Late referral, and limited facilities for renal replacement therapy explain the poor outcome in this study. We need a program to delineate the burden of chronic kidney disease and improve primary health care for health promotion and prevention of paediatric chronic kidney disease.

Abstract
To determine the incidence, etiology and treatment patterns of chronic kidney disease (CKD) in children a questionnaire was sent to pediatric nephrology centers in Turkey, asking them to report patients under the age of 19 years who had estimated glomerular filtration rates (GFRs) of <or=75 ml/min per 1.73 m(2) body surface area, diagnosed in 2005. Twenty-nine centers reported 282 patients (123 female/159 male; mean age 8.05 +/- 5.25 years). Urological problems such as vesicoureteral reflux (18.5%), obstructive uropathy (10.7%) and neurogenic bladder (15.1%) were the leading causes of CKD. The majority of the patients were in stage V (32.5%), IV (29.8%) or III (25.8%). Growth retardation (49.6%) and secondary hyperparathyroidism (72.4%) were very frequent. The GFR levels correlated positively with hemoglobin/hematocrit and calcium levels and negatively with phosphorus and parathyroid hormone (PTH) levels (P < 0.05). Renal replacement therapies were initiated in 35.8% of the patients, peritoneal dialysis in 23%, hemodialysis in 10.6% and transplantation in 2.2%. This was the first multi-center, epidemiologic study done in children with CKD in Turkey. The most striking result was the predominance of vesicoureteral reflux (VUR) or related urological problems as the underlying causes of CKD. Thus, early diagnosis and treatment of these conditions are of vital importance to decrease the incidence of CKD in children.

Abstract
The provision of tertiary paediatric nephrology facilities has led to increasing referrals of children with chronic renal failure (CRF). We report the aetiology and outcomes over 5 years, during which period the improving socio-economic situation has allowed increasing provision of dialysis and transplantation. The records of 205 children (124 male; 60.5%) who were referred to a tertiary paediatric nephrology unit in Khartoum between 2001 and 2006 with a glomerular filtration rate of less than 50 ml/min per 1.73 m(2) body surface area were reviewed. The mean age at the time of diagnosis with CRF was 9.8 years (range 3 months-17 years). The aetiology was chronic glomerulonephritis in 52 (25.4%), congenital urological malformations in 36 (17.5%), urolithiasis in 19 (9.3%), hereditary nephropathy in 14 (6.8%), multisystem diseases in 4 (2%), and cause unknown in 80 (39.1%). Of the 205 children, 136 (63%) had reached end-stage renal failure, with chronic haemodialysis being undertaken in 48 (35.3%), intermittent peritoneal dialysis in 43 (31.6%), continuous ambulatory peritoneal dialysis in 17 (14.7%), and no treatment in 25 (18.4%). At the end of the study period 53 of the 205 (25.9%) remained on dialysis, 51 (25%) were on conservative treatment, 8 (3.9%) had received transplants, 48 (23.4%) had died, and 45 (22%) had been lost to follow-up. The results illustrate the geographical variations in CRF aetiology in different countries, which may be influenced by current patterns of referral as well as environmental and society factors. The large number with an unknown aetiology for their CRF requires further prospective investigation. We hope the current high mortality rate will improve with earlier referral, improved nutrition, family support, and better access to treatment modalities, especially the provision of kidney transplantation from living related donors.

Abstract
The burden of chronic kidney disease (CKD) in children in developing countries remains unknown, due to the lack of a national data-reporting system. We undertook a retrospective study of all children < 16 years old in our hospital, which is the tertiary referral centre for children with complex kidney disorders, to analyse the spectrum of CKD (stages 2-5) from 1994-2006. Six hundred and fifty-three children with kidney disorders were screened for CKD; 286 (44.0%) were < 5 years old. Of these, 177 (62%) were male, 202 (70.6%) were black, 77 (26.9%) were Indian, five (1.8%) were mixed race and two (0.7%) were white. One hundred and twenty-six children had CKD (stages 2-5); 55 (43.7%) were < 5 years olds; 41 (74.5%) were male. There were 71 (56.3%) that were > 5 years old, 42 (59.2%) were male. The commonest cause of CKD (stages 2-5) in all children was nephrotic syndrome, comprising 30.9% in children < 5 years old and 40.8% in children > 5 years old. Within the observation period of 11 years, end-stage kidney disease was diagnosed in 20 children; only nine had been on long-term dialysis, and seven qualified for transplantation. Five (25%) children had died, four from sepsis during dialysis and one from tuberculosis after receiving a transplant. We concluded that lack of resources, late referrals, and high cost of renal replacement therapy in developing countries leads to poor outcome in CKD.

Abstract
We have retrospectively reviewed the records of children aged >1 month to 16 years who had been referred to the Department of Pediatrics of Prince of Songkla University's Faculty of Medicine, a tertiary referral center in Thailand, between 1982 and 2005 and subsequently diagnosed with chronic kidney disease (CKD). Our aim was to evaluate the prevalence and etiology of CKD in southern Thailand. There were 101 cases of CKD, with one case each diagnosed in 1988, 1989 and 1993, respectively, and 98 cases diagnosed between 1994 and 2005. These latter cases were divided into two 6-year periods: an early period (1994-1999), with 32 cases, and a later period (2000-2005), with 66 cases. The majority of this pediatric population with CKD were male (62/101, 61.4%). The etiologies of CKD were 35 cases of chronic glomerulonephritis (CGN) (34.7%), 29 of genitourinary tract (GU) anomalies (28.7%), nine of systemic lupus erythematosus (SLE) (8.9%), four malignancies (4.0%), four miscellaneous (4.0%) and 19 of unknown causes (18.8%). The patients were divided into age groups of <2 years (20 CKD patients), 2-6 years (15), >6-10 years (22), >10-13 years (20) and >13 years (24). The etiologies of CKD were significantly different in each age group, with GU anomalies and glomerulonephritis being the major causes of CKD in children aged <or=6 years (20/36, 55.6%) and >6 years (40/65, 61.5%), respectively. In conclusion, the incidence of CKD in our university hospital situation was not rare, with the prevalence doubling during the past 6 years, and the etiologies varying by age group.

Abstract
In contrast to the increasing availability of information pertaining to the care of children with chronic kidney disease (CKD) from large-scale observational and interventional studies, epidemiological information on the incidence and prevalence of pediatric CKD is currently limited, imprecise, and flawed by methodological differences between the various data sources. There are distinct geographic differences in the reported causes of CKD in children, in part due to environmental, racial, genetic, and cultural (consanguinity) differences. However, a substantial percentage of children develop CKD early in life, with congenital renal disorders such as obstructive uropathy and aplasia/hypoplasia/dysplasia being responsible for almost one half of all cases. The most favored end-stage renal disease (ESRD) treatment modality in children is renal transplantation, but a lack of health care resources and high patient mortality in the developing world limits the global provision of renal replacement therapy (RRT) and influences patient prevalence. Additional efforts to define the epidemiology of pediatric CKD worldwide are necessary if a better understanding of the full extent of the problem, areas for study, and the potential impact of intervention is desired.

Abstract
In contrast to the adult population, in whom a variety of registries have confirmed the incidence, prevalence, and diagnoses associated with chronic kidney disease (CKD), the epidemiological information on pediatric CKD is currently imprecise and flawed by methodological differences between the various data sources. Obstructive uropathy and congenital aplasia/hypoplasia/dysplasia are responsible for almost one half of all cases of CKD in children, underscoring the fact that a substantial percentage of the pediatric CKD population develops renal insufficiency very early in life. However, there are distinct geographic differences in the reported causes of CKD, in part because of environmental, racial, genetic, and cultural (consanguinity) differences. Furthermore, despite apparently comparable incidence rates, high mortality in countries that lack health care resources results in a low prevalence of CKD in those locations. In countries where renal replacement therapy is readily available, the most favored treatment modality is renal transplantation in all pediatric age groups. Additional efforts to define the epidemiology of pediatric CKD worldwide in a more uniform manner are necessary if a better understanding of the full extent of the problem, areas for study, and the potential impact of intervention is desired.
