The article focuses on the high rates of morbidity and mortality of paediatric acute kidney injuries (AKI) as a global public health issue. It cites on the higher rates for AKI in the low to middle income countries while lower in the higher income countries. The article also discusses the initiatives of the International Society of Nephrology (ISN) to address the global problem until 2025.

There is a dearth of data on end-stage renal disease (ESRD) in Africa. Several national renal registries have been established but have not been sustainable because of resource limitations. The African Association of Nephrology (AFRAN) and the African Paediatric Nephrology Association (AFPNA) recognize the importance of good registry data and plan to establish an African Renal Registry. This article reviews the elements needed for a successful renal registry and gives an overview of renal registries in developed and developing countries, with the emphasis on Africa. It then discusses the proposed African Renal Registry and the first steps towards its implementation. A registry requires a clear purpose, and agreement on inclusion and exclusion criteria, the dataset and the data dictionary. Ethical issues, data ownership and access, the dissemination of findings and funding must all be considered. Well-documented processes should guide data collection and ensure data quality. The ERAEDTA Registry is the world's oldest renal registry. In Africa, registry data have been published mainly by North African countries, starting with Egypt and Tunisia in 1975. However, in recent years no African country has regularly reported national registry data. A shared renal registry would provide participating countries with a reliable technology platform and a common data dictionary to facilitate joint analyses and comparisons. In March 2015, AFRAN organized a registry workshop for African nephrologists and then took the decision to establish, for the first time, an African Renal Registry. In conclusion, African nephrologists have decided to establish a continental renal registry. This initiative could make a substantial impact on the practice of nephrology and the provision of services for adults and children with ESRD in many African countries. [ABSTRACT FROM AUTHOR]

Acute kidney injury (AKI) is estimated to occur in approximately 13.3 million patients per year with an estimated mortality of 1.7 million. Approximately 85% of cases occur in low-resource settings where access to kidney replacement therapy (KRT) may be limited or nonexistent. The true extent of AKI, including access to KRT in developing countries, is largely unknown because appropriate systems are not in place to detect AKI or report it. Barriers to provision of KRT in low-resource settings revolve around systems management and funding, however, there also are region-specific issues. This review focuses on the epidemiology, obstacles, and solutions to improving access to KRT for AKI. [Display omitted] [Display omitted] [ABSTRACT FROM AUTHOR]

In the absence of malignancy or other severe comorbidity, kidney transplantation offers better survival rates and quality of life than dialysis. Despite this survival advantage, many lower- and upper-middle–income countries do not offer adequate kidney transplant services. This is particularly troubling because end-stage kidney disease often is more common in these countries than in high-income countries and overall is less costly in the life of a patient. We describe the contrasting levels of provision of kidney transplantation in Mexico, India, Nigeria, Ghana, and Zimbabwe, and kidney transplant services for children in Africa.

Introduction: Derangement in serum electrolytes and kidney function is often overlooked, especially in resource-constrained settings, and associated with increased risk of morbidity and mortality. This study aimed to describe the burden of derangements in serum electrolytes and kidney function in children presenting to a tertiary hospital in Nigeria. Methods: The laboratory records of all children who had serum electrolytes urea and creatinine ordered on their first presentation to hospital between January 1 and June 30, 2017 were retrospectively reviewed. Basic demographic data including admission status (inpatient or outpatient) were recordedandserum levels of sodium, potassium, chloride and bicarbonate were assessed for derangements usingnormal values from established reference ranges. Results of repeat samples were excluded. Kidney function was classified based on the serum creatinine relative to normal values for age and sex. Results: During the study period, 1909 children (60.3% male); median (IQR) age 42 (11.9) months had serum chemistry and 1248 (65.4%) were admitted. Results of their first samples were analyzed. Electrolyte derangements were present in 78.6% of the samples most commonly hyponatraemia (41.1%), low bicarbonate(37.2%), hypochloraemia (33.5%) and hypokalemia(18.9%). Azotaemia was found in 20.1% of the results. Elevated serum creatinine levels were found in 399 children (24.7%), 24.1% of those being in the severe category. Children aged 5 years and younger accounted for 76.4% of those with derangement in kidney function. One hundred and eight outpatients (17.8%) had deranged kidney function. Conclusion: Deranged serum electrolytes and kidney function were common in this cohort. [ABSTRACT FROM AUTHOR]

Pneumocystis jirovecii pneumonia (PJP) prophylaxis after pediatric solid organ transplant (SOT) is routinely recommended, but practice varies. Online survey was sent in 2018 to 707 members of the International Pediatric Transplant Association. A total of 105 responded, representing 47 institutions in 18 countries consisting of transplant physicians (66%), transplant surgeons (19%), nurse practitioners (6%), infectious disease physicians (5%), or pharmacists (4%). PJP prophylaxis was reported by 88%, while 12% did not routinely give prophylaxis. The majority not using PJP prophylaxis performed renal transplants (67%) citing low incidence of PJP (62%). Trimethoprim/sulfamethoxazole was first‐line agent (95%). PJP prophylaxis for 4‐6 months was the most frequent duration following kidney (48%, 27/56), liver (42%, 13/31), and heart (40%, 10/25) transplant. Abdominal multivisceral providers equally gave 10‐12 months (47%) or lifelong (47%); most lung transplant providers gave lifelong prophylaxis (85%). Across all organs, 21% provided lifetime prophylaxis. After completion of prophylaxis, 32% do not restart for any reason; majority of the rest would restart for treatment of acute graft rejection. 83% reported no PJP cases in the prior 12 months; 14% reporting 1‐5 infections. Only 3% reported a case of PJP infection on prophylaxis; none in SOT. PJP prophylaxis is routinely provided to pediatric SOT patients though practice and duration vary by center and organ type. Durations of 4‐6 months were most common for renal, liver, and heart transplant recipients, while 10‐12 months or lifelong prophylaxis were commonly reported for abdominal multivisceral recipients and most lung transplant recipients are given lifelong prophylaxis.

Background: Kidney transplantation remains the treatment of choice for children with kidney failure (KF). In South Africa, kidney replacement therapy (KRT) is restricted to children eligible for transplantation. This study reports on the implementation of the Paediatric Feasibility Assessment for Transplantation (pFAT) tool, a psychosocial risk score developed in South Africa to support transparent transplant eligibility assessment in a low‐resource setting. Methods: Single‐center retrospective descriptive analysis of children assessed for KRT using pFAT tool from 2015 to 2021. Results: Using the pFAT form, 88 children (median [range] age 12.0 [1.1 to 19.0] years) were assessed for KRT. Thirty (34.1%) children were not listed for KRT, scoring poorly in all domains, and were referred for supportive palliative care. Fourteen of these 30 children (46.7%) died, with a median survival of 6 months without dialysis. Nine children were reassessed and two were subsequently listed. Residing >300 km from the hospital (p =.009) and having adherence concerns (p =.003) were independently associated with nonlisting. Of the 58 (65.9%) children listed for KRT, 40 (69.0%) were transplanted. One‐year patient and graft survival were 97.2% and 88.6%, respectively. Only one of the four grafts lost at 1‐year posttransplant was attributed to psychosocial issues. Conclusions: Short‐term outcomes among children listed using the pFAT form are good. Among those nonlisted, the pFAT highlights specific psychosocial/socioeconomic barriers, over which most children themselves have no power to change, which should be systemically addressed to permit eligibility of more children and save lives.

Introduction: The presence of infections in the immediate pretransplant period poses challenges in decision‐making. Delaying transplantation because of these infections may be required, but is associated with a risk to the potential recipient. The aim of this project was to develop a structured framework based on expert opinion to guide decision‐making regarding the safety of transplantation for candidates with infection immediately before transplant, and to show how this framework can be applied to clinical scenarios. Methods: Categories were created as follows: Category A: no delay; Category B: brief delay (≤1 week); Category C: intermediate delay (>1 week); and Category D: more prolonged or indefinite delay. A survey containing 59 clinical scenarios was sent to members of the IPTA ID CARE committee. Answers were reviewed, and the level of agreement was characterized as follows: Level 1: ≥75% agreement; Level 2:51%‐74% agreement; and Level 3: ≤50% agreement. 95% CIs were calculated for the mean overall agreement across 59 scenarios. Results: Among the panel, the agreement level ranged from 33% to 92% with the mean overall agreement across the 59 scenarios being 61%. For 7/59 scenarios, the lower bound of 95% CI was greater than 50%, indicating a difference at the 5% level of significance between the observed proportion and the chance level of 0.5. Summary: The document provides expert opinion regarding the need to delay transplantation in the setting of different infections. The most important points in the decision to proceed to SOT included the urgency of transplantation and the severity of infection. [ABSTRACT FROM AUTHOR]

Introduction: Health‐related quality of life (HRQoL) studies demonstrate the impact of end‐stage renal disease (ESRD) on the physical and psychosocial development of children. While several instruments are used to measure HRQoL, few have standardized domains specific to pediatric ESRD. This review examines current evidence on self and proxy‐reported HRQoL among pediatric patients with ESRD, based on the Pediatric Quality of Life Inventory (PedsQL) questionnaires. Methods: Following PRISMA guidelines, we conducted a systematic review and meta‐analysis on HRQoL using the PedsQL 4.0 Generic Core Scale (GCS) and the PedsQL 3.0 ESRD Module among 5‐ to 18‐year‐old patients. We queried PubMed, Embase, Web of Science, CINAHL, and Cochrane databases. Retrospective, case‐controlled, and cross‐sectional studies using PedsQL were included. Findings: Of 435 identified studies, 14 met inclusion criteria administered in several countries. Meta‐analysis demonstrated a significantly higher total HRQoL for healthy patients over those with ESRD (SMD:1.44 [95% CI: 0.78–2.09]) across all dimensional scores. In addition, kidney transplant patients reported a significantly higher HRQoL than those on dialysis (PedsQL GCS, SMD: 0.33 [95% CI: 0.14–0.53]) and (PedsQL ESRD, SMD: 0.65 [95% CI: 0.39–0.90]) concordant with parent‐proxy reports. Discussion: Patients with ESRD reported lower HRQoL in physical and psychosocial domains compared with healthy controls, while transplant and peritoneal dialysis patients reported better HRQoL than those on hemodialysis. This analysis demonstrates the need to identify dimensions of impaired functioning and produce congruent clinical interventions. Further research on the impact of individual comorbidities in HRQoL is necessary for developing comprehensive, integrated, and holistic treatment programs. [ABSTRACT FROM AUTHOR]

Background: Diuretics are commonly used in neonatal AKI with the rationale to decrease positive fluid balance in critically sick neonates. The patterns of furosemide use vary among hospitals, which necessitates the need for a well-designed study. Methods: The TINKER (The Indian Iconic Neonatal Kidney Educational Registry) study provides a database, spanning 14 centres across India since August 2018. Admitted neonates (≤ 28 days) receiving intravenous fluids for at least 48 h were included. Neonatal KDIGO criteria were used for the AKI diagnosis. Detailed clinical and laboratory parameters were collected, including the indications of furosemide use, detailed dosing, and the duration of furosemide use (in days). Results: A total of 600 neonates with AKI were included. Furosemide was used in 8.8% of the neonates (53/600). Common indications of furosemide use were significant cardiac disease, fluid overload, oliguria, BPD, RDS, hypertension, and hyperkalemia. The odds of mortality was higher in neonates < 37 weeks gestational age with AKI who received furosemide compared to those who did not receive furosemide 3.78 [(1.60–8.94); p = 0.003; univariate analysis] and [3.30 (1.11–9.82); p = 0.03]; multivariate logistic regression]. Conclusions: In preterm neonates with AKI, mortality was independently associated with furosemide treatment. The furosemide usage rates were higher in neonates with associated co-morbidities, i.e. significant cardiac diseases or surgical interventions. Sicker babies needed more resuscitation at birth, and died early, and hence needed shorter furosemide courses. Thus, survival probability was higher in neonates treated with long furosemide courses vs. short courses. [ABSTRACT FROM AUTHOR]

Adolescents and Young Adults (AYAs) with chronic kidney disease (CKD) have challenges unique to this developmental period, with increased rates of high‐risk behavior and non‐adherence to therapy which may impact the progression of kidney disease and their requirement for kidney replacement therapy (KRT). Successful transition of AYA patients are particularly important in low‐ and middle‐income countries (LMICs) where KRT is limited, rationed or not available. Kidney AYA transition clinics have the potential to improve clinical outcomes but there is a paucity of data on the clinical translational impact of these clinics in Africa. This review is a reflection of the 20‐year growth and development of the first South African kidney AYA transition clinic. We describe a model of care for patients with CKD, irrespective of etiology, aged 10–25 years, transitioning from pediatric to adult nephrology services. This unique service was established in 2002 and re‐designed in 2015. This multidisciplinary integrated transition model has improved patient outcomes, created peer support groups and formed a training platform for future pediatric and adult nephrologists. In addition, an Adolescent Centre of Excellence has been created to compliment the kidney AYA transition model of care. The development of this transition pathway challenges and solutions are explored in this article. This is the first kidney AYA transition clinic in Africa. The scope of this service has expanded over the last two decades. With limited resources in LMICs, such as KRT, the structured transition of AYAs with kidney disease is not only possible but essential. It is imperative to preserve residual kidney function, maximize the kidney allograft lifespan and improve adherence, to enable young individuals an opportunity to lead productive lives.

Background: Acute kidney injury (AKI) is a frequent complication of children admitted to the paediatric intensive care unit. One key management modality of AKI is the use of diuretics to reduce fluid overload. Aminophylline, a drug that is well known for its use in the treatment of bronchial asthma, is also purported to have diuretic effects on the kidneys. This retrospective cohort study assesses the effect of aminophylline in critically ill children with AKI. Methods: A retrospective chart review of children admitted to the paediatric intensive care unit of the Red Cross War Memorial Children's Hospital (RCWMCH) with AKI who received aminophylline (from 2012 to June 2018) was carried out. Data captured and analyzed included demographics, underlying disease conditions, medications, urine output, fluid balance, and kidney function. Results: Data from thirty-four children were analyzed. Urine output increased from a median of 0.4 mls/kg/hr [IQR: 0.1, 1.1] at six hours prior to aminophylline administration to 0.6 mls/kg/hr [IQR: 0.2, 1.9] at six hours and 1.6 mls/kg/hr [IQR:0.2, 4.2] at twenty-four hours post aminophylline therapy. The median urine output significantly varied across the age groups over the 24-h time period post-aminophylline, with the most response in the neonates. There was no significant change in serum creatinine levels six hours post-aminophylline administration [109(IQR: 77, 227)—125.5(IQR: 82, 200) micromole/l] P-value = 0.135. However, there were significant age-related changes in creatinine levels at six hours post-aminophylline therapy. Conclusions: Aminophylline increases urine output in critically ill children with AKI. [ABSTRACT FROM AUTHOR]

An editorial highlights the pressing need for multidisciplinary teams in caring for children with atypical hemolytic uremic syndrome (aHUS). It emphasizes the challenges faced by patients and families due to the rarity and complexity of the disease, leading to delays in accurate diagnosis and treatment. It stresses the importance of prompt and thorough diagnosis, particularly given the urgent therapeutic implications of aHUS.

Streptococcus pyogenes (Strep A) infections result in a vastly underestimated burden of acute and chronic disease globally. The Strep A Vaccine Global Consortium's (SAVAC's) mission is to accelerate the development of safe, effective, and affordable S. pyogenes vaccines. The safety of vaccine recipients is of paramount importance. A single S. pyogenes vaccine clinical trial conducted in the 1960s raised important safety concerns. A SAVAC Safety Working Group was established to review the safety assessment methodology and results of more recent early-phase clinical trials and to consider future challenges for vaccine safety assessments across all phases of vaccine development. No clinical or biological safety signals were detected in any of these early-phase trials in the modern era. Improvements in vaccine safety assessments need further consideration, particularly for pediatric clinical trials, large-scale efficacy trials, and preparation for post-marketing pharmacovigilance.

Background: Despite its utility, uncertainty exists on the feasibility of acute peritoneal dialysis (PD) and optimal PD catheter type for very low birth weight (VLBW < 1500 g) and extremely low birth weight (ELBW < 1000 g) infants. We hereby report our experience of acute PD among these high-risk infants and compare the outcome between stylet-based rigid catheter (SRC) and Cook Mac-Loc Multipurpose Drainage catheters® (CMMDC). Methods: Case notes of infants < 1500 g undergoing PD between 2012 and 2021 in a network of five participating neonatal units supported by a tertiary paediatric nephrology centre in Kolkata, India, were retrospectively reviewed. PD was conducted either with SRC or after 2018 with CMMDC. Outcome parameters included complications, survival during PD, and survival to discharge. Results: 24 infants (VLBW: n = 13 and ELBW: n = 11) underwent PD at median age 4.5 days (IQR 3–6) with either CMMDC (n = 14) or SRC (n = 10). Significant improvement in biochemical parameters and fluid removal was seen in both ELBW and VLBW infants. CMMDC was associated with significantly fewer PD-related complications 7/14 (50%) vs. 9/10 (90%) (p = 0.04) and higher survival during PD 13/14 (93%) vs. 5/10 (50%) (p = 0.02), without significant difference in survival to hospital discharge 8/14 (57%) vs. 3/10 (30%) (p = 0.25). CMMDC also enabled longer duration of PD, higher ultrafiltration, and better control of acidosis. Consumable cost was higher for CMMDC (USD$60) than SRC (USD$14). Conclusions: In a low resource setting, CMMDC had lower PD complications and superior short-term survival among ELBW/VLBW infants.

Peritoneal dialysis (PD) is an important home-based treatment for kidney failure and accounts for 11% of all dialysis and 9% of all kidney replacement therapy globally. Although PD is available in 81% of countries, this provision ranges from 96% in high-income countries to 32% in low-income countries. Compared with haemodialysis, PD has numerous potential advantages, including a simpler technique, greater feasibility of use in remote communities, generally lower cost, lesser need for trained staff, fewer management challenges during natural disasters, possibly better survival in the first few years, greater ability to travel, fewer dietary restrictions, better preservation of residual kidney function, greater treatment satisfaction, better quality of life, better outcomes following subsequent kidney transplantation, delayed need for vascular access (especially in small children), reduced need for erythropoiesis-stimulating agents, and lower risk of blood-borne virus infections and of SARS-CoV-2 infection. PD outcomes have been improving over time but with great variability, driven by individual and system-level inequities and by centre effects; this variation is exacerbated by a lack of standardized outcome definitions. Potential strategies for outcome improvement include enhanced standardization, monitoring and reporting of PD outcomes, and the implementation of continuous quality improvement programmes and of PD-specific interventions, such as incremental PD, the use of biocompatible PD solutions and remote PD monitoring.
