RESUMO
BACKGROUND: Training caregivers performing PD is an important measure to prevent peritonitis. A low literacy rate hinders training in low-resource settings. We designed a structured training initiative (STI) and objective structured assessment (OSA) using visual and kinesthetic resources with minimal use of written resources. We studied the impact of STIs on caregivers' knowledge and practical skills and the rate of peritonitis. METHODS: This prospective study conducted initial STI (iSTI) for caregivers of children initiating PD and retraining STI (rSTI) for those already on PD. OSA was administered after completion of training, and those scoring < 95% were retrained. Re-assessment was done at 3, 6, and 12 months, and those who scored < 95% underwent re-training. The rate of PD peritonitis and the time to first peritonitis were compared between the STI group and the cohort on PD in our center who received standard training before STI (controls). RESULTS: Caregivers of 40 children were included. The median duration of iSTI and rSTI was 19.5 (18, 20) and 9 (9, 9.5) hrs, and the OSA scores were 97% (97%, 98%) and 96% (96%, 98%), respectively. Only 5% required retraining. There was a significant reduction in the rate of PD peritonitis (0.29 vs. 0.69 episodes/patient-year; p < 0.001) and longer time to peritonitis (189 vs. 69 days; p < 0.001) in the STI group when compared to the controls (n = 32). CONCLUSIONS: STI was effective in training caregivers for peritoneal dialysis. There was a reduction in the rate of peritonitis and a longer time to first peritonitis in the STI cohort.
RESUMO
We present updated, evidence-based clinical practice guidelines from the Indian Society of Pediatric Nephrology (ISPN) for the management of urinary tract infection (UTI) and primary vesicoureteric reflux (VUR) in children. These guidelines conform to international standards; Institute of Medicine and AGREE checklists were used to ensure transparency, rigor, and thoroughness in the guideline development. In view of the robust methodology, these guidelines are applicable globally for the management of UTI and VUR. Seventeen recommendations and 18 clinical practice points have been formulated. Some of the key recommendations and practice points are as follows. Urine culture with > 104 colony forming units/mL is considered significant for the diagnosis of UTI in an infant if the clinical suspicion is strong. Urine leukocyte esterase and nitrite can be used as an alternative screening test to urine microscopy in a child with suspected UTI. Acute pyelonephritis can be treated with oral antibiotics in a non-toxic infant for 7-10 days. An acute-phase DMSA scan is not recommended in the evaluation of UTI. Micturating cystourethrography (MCU) is indicated in children with recurrent UTI, abnormal kidney ultrasound, and in patients below 2 years of age with non-E. coli UTI. Dimercaptosuccinic acid scan (DMSA scan) is indicated only in children with recurrent UTI and high-grade (3-5) VUR. Antibiotic prophylaxis is not indicated in children with a normal urinary tract after UTI. Prophylaxis is recommended to prevent UTI in children with bladder bowel dysfunction (BBD) and those with high-grade VUR. In children with VUR, prophylaxis should be stopped if the child is toilet trained, free of BBD, and has not had a UTI in the last 1 year. Surgical intervention in high-grade VUR can be considered for parental preference over antibiotic prophylaxis or in children developing recurrent breakthrough febrile UTIs on antibiotic prophylaxis.

BACKGROUND: Three types of primary hyperoxaluria (PH) are recognized. However, data on PH type 2 (PH2), caused by defects in the GRHPR gene, are limited. METHODS: We reviewed the medical records of patients < 18 years of age with genetically-proven PH2 from seven centres across India to identify the age of onset, patterns of clinical presentation, short-term outcomes and genetic profile, and to determine if genotype-phenotype correlation exists. RESULTS: We report 20 patients (all with nephrolithiasis or nephrocalcinosis) diagnosed to have PH2 at a median (IQR) age of 21.5 (7, 60) months. Consanguinity and family history of kidney stones were elicited in nine (45%) and eight (40%) patients, respectively. The median (IQR) serum creatinine at PH2 diagnosis was 0.45 (0.29, 0.56) mg/dL with the corresponding estimated glomerular filtration rate being 83 (60, 96) mL/1.73 m2/min. A mutational hotspot (c.494 G > A), rare in Caucasians, was identified in 12 (60%) patients. An intronic splice site variant (c.735-1G > A) was noted in five (25%) patients. Four (20%) patients required surgical intervention for stone removal. Major adverse kidney events (mortality or chronic kidney disease (CKD) stages 3-5) were noted in six (30%) patients at a median (IQR) follow-up of 12 (6, 27) months. Risk factors for CKD progression and genotype-phenotype correlation could not be established. CONCLUSIONS: PH2 should no longer be considered an innocuous disease, but rather a potentially aggressive disease with early age of presentation, and possible rapid progression to CKD stages 3-5 in childhood in some patients. A mutational hotspot (c.494 G > A variant) was identified in 60% of cases, but needs further exploration to decipher the genotype-phenotype correlation.

The nephrology and critical care communities have seen an increase in studies exploring acute kidney injury (AKI) epidemiology in children. As a result, we now know that AKI is highly prevalent in critically ill neonates, children, and young adults. Furthermore, children who develop AKI experience greater morbidity and higher mortality. Yet knowledge gaps still exist that suggest a more comprehensive understanding of AKI will form the foundation for future efforts designed to improve outcomes. In particular, the areas of community acquired AKI, AKI in non-critically ill children, and cohorts from low-middle income countries have not been well studied. Longer-term functional outcomes and patient-centric metrics including social determinants of health, quality of life, and healthcare utilization should be the foci of the next phase of scholarship. Current definitions identify AKI-based upon evidence of dysfunction which serves as a proxy for injury; biomarkers capable of identifying injury as it occurs are likely to more accurately define populations with AKI. Despite the strength of the association, the causal and mechanistic relationships between AKI and poorer outcomes remain inadequately examined. A more robust understanding of the relationship represents a potential to identify therapeutic targets. Once established, a more comprehensive understanding of AKI epidemiology in children will allow investigation of preventive, therapeutic, and quality improvement interventions more effectively.

BACKGROUND: Acute kidney injury (AKI) is independently associated with increased morbidity and mortality across the life course, yet care for AKI remains mostly supportive. Raising awareness of this life-threatening clinical syndrome through education and advocacy efforts is the key to improving patient outcomes. Here, we describe the unique roles education and advocacy play in the care of children with AKI, discuss the importance of customizing educational outreach efforts to individual groups and contexts, and highlight the opportunities created through innovations and partnerships to optimize lifelong health outcomes. METHODS: During the 26th Acute Disease Quality Initiative (ADQI) consensus conference, a multidisciplinary group of experts discussed the evidence and used a modified Delphi process to achieve consensus on recommendations on AKI research, education, practice, and advocacy in children. RESULTS: The consensus statements developed in response to three critical questions about the role of education and advocacy in pediatric AKI care are presented here along with a summary of available evidence and recommendations for both clinical care and research. CONCLUSIONS: These consensus statements emphasize that high-quality care for patients with AKI begins in the community with education and awareness campaigns to identify those at risk for AKI. Education is the key across all healthcare and non-healthcare settings to enhance early diagnosis and develop mitigation strategies, thereby improving outcomes for children with AKI. Strong advocacy efforts are essential for implementing these programs and building critical collaborations across all stakeholders and settings.

BACKGROUND: The effect of different dosing regimens of cholecalciferol supplementation on bone biomarkers has not been studied in children with chronic kidney disease (CKD). METHODS: This is a post hoc analysis of a multi-center randomized controlled trial which included children with CKD stages 2-4 with vitamin D deficiency (25-hydroxy vitamin D (25OHD) < 30 ng/ml) randomized 1:1:1 to receive an equivalent dose of oral cholecalciferol as daily, weekly or monthly treatment. Markers of bone formation (bone alkaline phosphatase (BAP), procollagen I N terminal peptide (PINP)), bone resorption (tartarate-resistant acid phosphatase 5b (TRAP), C terminal telopeptide (CTX)), and osteocyte markers (intact fibroblast growth factor 23 (iFGF23), sclerostin) and soluble klotho were measured at baseline and after 3 months of intensive replacement therapy. The change in biomarkers and ratio of markers of bone formation to resorption were compared between treatment arms. BAP and TRAP were expressed as age- and sex-specific z-scores. RESULTS: 25OHD levels increased with cholecalciferol supplementation, with 85% achieving normal levels. There was a significant increase in the BAP/TRAP ratio (p = 0.04), iFGF23 (p = 0.004), and klotho (p = 0.002) with cholecalciferol therapy, but this was comparable across all three therapy arms. The BAPz was significantly higher in the weekly arm (p = 0.01). The change in 25OHD (Δ25OHD) inversely correlated with ΔPTH (r = - 0.4, p < 0.001). CONCLUSIONS: Although cholecalciferol supplementation was associated with a significant increase in bone formation, the three dosing regimens of cholecalciferol supplementation have a comparable effect on the bone biomarker profile, suggesting that they can be used interchangeably to suit the patient's needs and optimize adherence to therapy. A higher resolution version of the Graphical abstract is available as Supplementary information.

The nutritional status and management of children with chronic kidney disease (CKD) are complex and require a combined pediatric nephrology team work approach with physicians, nutritionists, nurses, and physical/occupational therapists. Prospective observational studies such as Children with CKD in the US, the 4C study in Europe and the International Pediatric Peritoneal Dialysis Network have advanced the field. However, most recommendations and guidelines from international task forces such as Kidney Diseases Improving Global Outcomes and Pediatric Renal Nutrition Taskforce are opinion-based rather than evidence-based. There is exciting ongoing research to improve nutrition in children with CKD to help them thrive.

INTRODUCTION: Arteriovenous fistula (AVF) is the recommended access of choice in children on maintenance hemodialysis. The challenges of creating and maintaining a fistula in children are many. The objective of our study was to describe the clinical profile and outcomes of AVFs in children from a resource-limited setting. METHODS: A retrospective analysis of children who have had an AVF for maintenance hemodialysis from 2010 to 2020 was performed. The center protocol for creation and management of complications was followed. Failure of fistula to mature was defined as primary failure. Primary patency was defined as the time from creation of access to the first complication requiring intervention. The primary failure rate, duration of primary patency and associated risk factors, and 1- and 3-year primary fistula patency rates were studied. RESULTS: Thirty-six children (38 AVFs) with the median (interquartile range) age of 11 (8, 13) years were included. Brachiocephalic anastomosis was the most common site (75%) of AVF. The primary failure rate was 5.5% (2 of 36). The mean (95% confidence interval) duration of primary patency was 42.3 (29.9, 54.7) months. There were no particular factors associated with the duration of primary patency. The 1- and 3-year primary patency rate was 91% and 73%, respectively. CONCLUSIONS: In resource-limited settings, AVF had good primary patency and is a feasible and durable access for maintenance hemodialysis in children.

BACKGROUND: The optimal treatment regimen for correcting 25-hydroxyvitamin D (25OHD) deficiency in children with chronic kidney disease (CKD) is not known. We compared cholecalciferol dosing regimens for achieving and maintaining 25OHD concentrations ≥30 ng/mL in children with CKD stages 2-4. METHODS: An open-label, multicentre randomized controlled trial randomized children with 25OHD concentrations <30 ng/mL in 1:1:1 to oral cholecalciferol 3000 IU daily, 25 000 IU weekly or 100 000 IU monthly for 3 months (maximum three intensive courses). In those with 25OHD ≥30 ng/mL, 1000 IU cholecalciferol daily (maintenance course) was given for up to 9 months. Primary outcome was achieving 25OHD ≥30 ng/mL at the end of intensive phase treatment. RESULTS: Ninety children were randomized to daily (n = 30), weekly (n = 29) or monthly (n = 31) treatment groups. At the end of intensive phase, 70/90 (77.8%) achieved 25OHD ≥30 ng/mL; 25OHD concentrations were comparable between groups (median 44.3, 39.4 and 39.3 ng/mL for daily, weekly and monthly groups, respectively; P = 0.24) with no difference between groups for time to achieve 25OHD ≥30 ng/mL (P = 0.28). There was no change in calcium, phosphorus and parathyroid hormone, but fibroblast growth factor 23 (P = 0.002) and klotho (P = 0.001) concentrations significantly increased and were comparable in all treatment groups. Irrespective of dosing regimen, children with glomerular disease had 25OHD concentrations lower than non-glomerular disease (25.8 versus 41.8 ng/mL; P = 0.007). One child had a 25OHD concentration of 134 ng/mL, and 5.5% had hypercalcemia without symptoms of toxicity. CONCLUSION: Intensive treatment with oral cholecalciferol as daily, weekly or monthly regimens achieved similar 25OHD concentrations between treatment groups, without toxicity. Children with glomerular disease required higher doses of cholecalciferol compared with those with non-glomerular disease.

AIMS: The prevalence of vitamin D deficiency is high in children with chronic kidney disease (CKD). However, current dosing recommendations are based on limited pharmacokinetic (PK) data. This study aimed to develop a population PK model of colecalciferol that can be used to optimise colecalciferol dosing in this population. METHODS: Data from 83 children with CKD were used to develop a population PK model using a nonlinear mixed effects modelling approach. Serum creatinine and type of kidney disease (glomerular vs. nonglomerular disease) were investigated as covariates, and optimal dosing was determined based on achieving and maintaining 25-hydroxyvitamin D (25(OH)D) concentration of 30-48 ng/mL. RESULTS: The time course of 25(OH)D concentrations was best described by a 1-compartment model with the addition of a basal concentration parameter to reflect endogenous 25(OH)D production from diet and sun exposure. Colecalciferol showed wide between-subject variability in its PK, with total body weight scaled allometrically the only covariate included in the model. Model-based simulations showed that current dosing recommendations for colecalciferol can be optimised using a weight-based dosing strategy. CONCLUSION: This is the first study to describe the population PK of colecalciferol in children with CKD. PK model informed dosing is expected to improve the attainment of target 25(OH)D concentrations, while minimising the risk of overdosing.

Kidney transplantation is the ideal choice of kidney replacement therapy in children as it offers a low risk of mortality and a better quality of life. A wide variance in the access to kidney replacement therapies exists across the world with only 21% of low- and low-middle income countries (LLMIC) undertaking kidney transplantation. Pediatric kidney transplantation rates in these under-resourced regions are reported to be as low as < 4 pmcp [per million child population]. A robust kidney failure care program forms the cornerstone of a transplant program. Even the smallest transplant program entails a multidisciplinary workforce and expertise besides ensuring family commitment towards long-term care and economic burden. In general, the short-term graft survival rates from under-resourced regions are comparable to most high-income countries (HIC) and the challenge lies in the long-term outcomes. This review focuses on specific issues relevant to kidney transplants in children in under-resourced regions by highlighting limitations in the capacity and health workforce, regulatory norms, medical issues, economic burden, factors beyond financial hardship and ethical considerations relevant to these regions. Finally, the perspective of strengthening transplant programs in these regions should factor in the bigger challenges that exist in achieving the health-related sustainable development goals by 2030.

BACKGROUND: Congenital anomalies of the kidney and urinary tract (CAKUT) cover a spectrum of structural malformations that result from aberrant morphogenesis of kidney and urinary tract. It is the most prevalent cause of kidney failure in children. Hence, it is important from a clinical perspective to unravel the molecular etiology of kidney and urinary tract malformations. Causal variants in genes that direct various stages of development of kidney and urinary tract in fetal life have been identified in 5-20% of CAKUT patients from Western countries. Recent advances in next generation sequencing technology and decreasing cost offer the opportunity to characterize the genetic profile of CAKUT in Indian population and facilitate integration of genetic diagnostics in care of children with CAKUT. METHODS: Customized targeted panel sequencing was performed to identify pathogenic variants in 31 genes known to cause human CAKUT in 69 south Indian children with CAKUT. The NGS data was filtered using standardized pipeline and the variants were classified using ACMG criteria. Genotype and phenotype correlations were performed. RESULTS: The cohort consisted of children mostly with posterior urethral valve (PUV) (39.1%), vesico-ureteric reflux (VUR) (33.3%) and multi-cystic dysplastic kidney (MCDK) (7.2%). No pathogenic or likely pathogenic variants were identified in the study. Most of our variants (n = 39, 60%) were variants of unknown significance with 25.6% (10/39) of them were identified as potentially damaging but were novel variants. CONCLUSIONS: The present study did not identify any disease-causing monogenic variants in the cohort. The absence of genetic cause may be due to limitations of panel-based testing and also due to higher proportion of children with abnormalities in lower urinary tract than hypodysplasia of kidneys. Clinical, larger targeted panel or whole exome sequencing may be a better method to characterize the genetic profile of Indians patients with CAKUT.

After 2 decades as a low-cost transplant centre in India, our rates of kidney transplantation are low compared to the burden of end-stage kidney disease (ESKD). We performed this study to identify possible barriers inhibiting paediatric kidney transplant and to assess the outcomes of paediatric ESKD. A retrospective chart review of ESKD patients (2013 - 2018) at a tertiary paediatric nephrology centre was conducted. Medical/non-medical barriers to transplant were noted. Patient outcomes were classified as "continued treatment," "lost to follow-up (LTFU)" or "died." Of 155 ESKD patients (monthly income 218 USD [146, 365], 94% self-pay), only 30 (19%) were transplanted (28 living donor). Sixty-five (42%) were LTFU, 19 (12%) died, and 71 (46%) continued treatment. LTFU/death was associated with greater travel distance (300 km [60, 400] vs 110 km [20, 250] km, P < .0001) and lower monthly income (145 USD [101, 290] vs 290 USD [159, 681], P < .0001). Among those who continued treatment, 41 proceeded to transplant evaluation of whom 13 had no living donor and remained waitlisted for 27 months (15, 30). The remainder (n = 30) did not proceed to transplant due to unresolved medical issues (n = 10) or a lack of parental interest in pursuing transplant (n = 20). Barriers to transplantation in low-resource setting begin in ESKD. LTFU resulted in withdrawal of care and was associated with low socioeconomic status. Among those who continued treatment, transplant rates were higher but medical challenges and negative attitudes towards transplant and organ donation occurred.

OBJECTIVES: Protein energy wasting (PEW), a specific nutritional comorbidity associated with increased mortality, is underrecognized in children with chronic kidney disease (CKD). The aim of this study was to determine the burden and factors associated with PEW and assess the utility of parameters used to diagnose PEW in children with CKD and End stage kidney disease (ESKD). METHODS: Children between 2 and 18 years of age with CKD stages 2-5 were recruited over 30 months. Parameters of PEW assessed included body mass index for height, mid-upper arm circumference, height for age, appetite, serum albumin, cholesterol, transferrin, and C-reactive protein. Based on number of criteria fulfilled in each subject, PEW was further stratified as mild, standard, and modified PEW. RESULTS: One hundred twenty-three children (male:female 3:1, 73 in CKD stages 2-4, 50 with ESKD) were recruited. PEW was observed in 58% (47% in CKD stages 2-4 vs. 73% ESKD, P = .035). Longer duration and severity of disease was associated PEW. Reduced appetite (P = .001, P = .04), low mid-upper arm circumference (P = .000, P = .006), and low body mass index for height (P = .000, P = .007) were useful criteria to diagnose PEW in CKD stages 2-4 and ESKD, while most children did not meet biochemical criteria. Inflammation observed in 47% was higher in those with ESKD [CKD stages 2-4: 72 (39%) vs. ESKD: 29 (59%), P = .02] but was associated with PEW only in CKD stages 2-4. CONCLUSION: PEW was highly prevalent in children with CKD and ESKD. Appetite and anthropometry measures were more useful than biochemical criteria for diagnosis of PEW. Whereas inflammation was common, it was associated with PEW only in CKD stages 2-4. Pediatric CKD and ESKD may need exclusive diagnostic criteria for PEW based on anthropometry, appetite, and inflammation.

HTN after renal transplantation is associated with cardiovascular morbidity. ABPM allows diagnosis of masked HTN and isolated nocturnal HTN. Longitudinal ABPM data in children post-transplant are limited. ABPM was performed in children post-transplant and repeated in 6-12 months. BP indices were used to determine the prevalence of masked HTN, masked uncontrolled HTN (masked HTN in patients on antihypertensive medications), and isolated nocturnal HTN. Linear regression determined the association between LVMI and ABPM indices. Thirty children underwent a baseline ABPM. Ambulatory HTN was present in 25 (83%). Masked HTN was present in 18 (60%) and isolated nocturnal HTN in 13 (43%). Nocturnal ambulatory BP was higher than corresponding daytime BPs (P < .001 for systolic and diastolic) and 25 (83%) had a blunted nocturnal dip. Prednisone dose predicted nocturnal DBP index and DBP load (r2 = .40, P = .024 and r2 = .178, P = .02). ABPM was repeated in 18 patients within 11 (±3) months. BP indices decreased with time, but nocturnal BPs remained higher than daytime (P < .001 for SBP and DBP). Blunted nocturnal dip did not improve. LVH was present in 12 (57%). LVMI was directly related to the nocturnal SBP index (r2 = .377, P = .003) and nocturnal DBP index (r2 = .493, P < .001). We found no association between LVMI and daytime BP indices. The prevalence of masked HTN, isolated nocturnal HTN, and blunted nocturnal dip was high in children with kidney transplants. Nocturnal BP predicted LVMI. Ambulatory BP improved on longitudinal follow-up, but the pattern of isolated nocturnal HTN persisted.

In this article, we first review the development of clinical ethics in pediatrics in the United States. We report that, over the last 40 years, most children's hospitals have ethics committees but that those committees are rarely consulted. We speculate that the reasons for the paucity of ethics consults might be because ethical dilemmas are aired in other venues. The role of the ethics consultant, then, might be to shape the institutional climate and create safe spaces for the discussion of difficult and sometimes contentious issues. Finally, we report how pediatric clinical ethics has evolved differently in a number of other countries around the world.

PURPOSE OF REVIEW: To assess the use, access to and outcomes of hemodialysis and peritoneal dialysis in low-resource settings. RECENT FINDINGS: Hemodialysis tends to predominate because of costs and logistics, however services tend to be located in larger cities, often paid for out of pocket. Outcomes of dialysis-requiring acute kidney injury and end-stage kidney disease may be similar with hemodialysis and peritoneal dialysis, and therefore choice of therapy is dominated by availability, accessibility and patient or physician choice. Some countries have implemented peritoneal dialysis-first policies to reduce costs and improve access, because peritoneal dialysis requires less infrastructure, can be scaled up more easily and can be cheaper when fluids are manufactured locally. SUMMARY: Access to both hemodialysis and peritoneal dialysis remains highly inequitable in lower-resource settings. Although challenges associated with dialysis in low-resource settings are similar, and there are more adults who require dialysis in low-resource settings, addressing hemodialysis and peritoneal dialysis needs of children in low-resource settings requires attention as the global inequities are greatest in this area. Lower-income countries are increasingly seeking to improve access to dialysis through various strategies, but meeting the costs of the entire dialysis population continues to be a major challenge.

Tropical infections are caused by a variety of bacteria, viruses and parasitic organisms across varying geographical regions and are more often reported in adults than in children. Most of the infections are acute, presenting as a febrile illness with involvement of multiple organ systems, including the kidney. The gamut of renal manifestations extends from asymptomatic urinary abnormalities to acute kidney injury and-albeit rarely-chronic kidney disease. Tropical infections can involve the glomerular, tubulointerstitial and vascular compartments of the kidney. Leptospirosis, malaria, dengue, rickettsial fever and schistosomiasis are the most prevalent tropical infections which affect the kidneys of children living in the tropics. In this review we discuss renal involvement in these most prevalent tropical infections.

Background: Early clinical exposure is likely to be beneficial during the preclinical year. This pilot programme aimed to define a learning framework of introducing first year medical students to early clinical exposure through a vertical integration programme in the physiology course. The intent was to enhance the understanding of theoretical concepts and practical applications of physiology. Student and faculty perceptions were evaluated. Methods: First year MBBS students (n = 60) had bedside clinics conducted by 5 clinical departments, where the clinical context and applied physiological concepts were emphasized. Clinical sessions were synchronized with pedagogic highlights on related physiological concepts. The student's perceptions were recorded through a semi-structured questionnaire, while qualitative feedback was obtained from the faculty. Results: All students ( 100%) reported that the programme was relevant and did not interfere with their physiology course. Most (91%) appreciated the synchronization of classroom knowledge with clinical exposures, and thought that integrated teaching helped in better understanding of practical applications of physiology (94%) with adequate discussions during the sessions (91 %). Fifty-nine (98%) students preferred integrated teaching over the isolated traditional classroom teaching. The clinicians involved also felt that the early clinical exposure was relevant. The students achieved a mean (SD) score of 13 (2.98) of 25 in the quiz consisting of multiple-choice questions that attempted to test their learning through early clinical exposures. Conclusion: This pilot exercise showed the utility of early clinical exposure integrated into the physiology course. It will be worthwhile to replicate this exercise at other institutions and among a larger student strength.

Limited access to tertiary-level health care, limited trained pediatric nephrologists and transplant physicians, lack of facilities for dialysis, lack of an effective deceased donor program, non-affordability, and non-adherence to immunosuppressant drugs poses a major challenge to universal availability of pediatric transplantation in developing countries. We present the results of a survey which, to the best of our knowledge, is the first such published attempt at understanding the current state of pediatric renal transplantation in India. A designed questionnaire formulated by a group of pediatric nephrologists with the aim of understanding the current practice of pediatric renal transplantation was circulated to all adult and pediatric nephrologists of the country. Of 26 adult nephrologists who responded, 16 (61.5%) were involved in pediatric transplantation, and 10 of 15 (66.6%) pediatric nephrologists were involved in pediatric transplantation. Most of the centers doing transplants were private/trust institution with only three government institutions undertaking it. Induction therapy was varied among pediatric and adult nephrologists. There were only a few centers (n=5) in the country routinely doing >5 transplants per year. Preemptive transplants and protocol biopsies were a rarity. The results demonstrate lower incidence of undertaking pediatric transplants in children below 6 years, paucity of active cadaveric programs and lack of availability of trained pediatric nephrologists and staff. In contrast to these dissimilarities, the immunosuppressant use seems to be quite similar to Western registry data with majority favoring induction agent and triple immunosuppressant (steroid, mycophenolate mofetil and tacrolimus) for maintenance. The survey also identifies major concerns in availability of this service to all regions of India as well as to all economic segments.
