Item Factors associated with mortality and long-term outcomes of pediatric acute kidney injury in a resource limited setting(Karger AG, Basel, 2023) Alao, M. A.; Ibrahim, O. R.; Ademola, A. D.; Asinobi, A. O.Introduction: Despite being a leading cause of morbidity and mortality globally, acute kidney injury (AKI) is worse in resource-limited areas. This study explores AKI incidence, in-hospital mortality, and long-term outcomes in resource limited settings. Methods: This was a prospective study of children with AKI from2014 to 2019. KDIGO 2012 defined AKI. We assessed the etiology, in-hospital mortality, and long-term outcome of AKI in a mission hospital. Results: Only 169 of 201 AKI patients had complete data. The ages ranged from 1.08 months to 17.5 years; 65.7% were male and 65.1% were from lower socioeconomic class. The incidence of AKI was 59.6 cases per 1,000 persons (95%CI: 5.42, 47.1). Most patients had stage 1 KDIGO AKI (91; 53.8%). 1–5 years old had the highest incidence of AKI (65; 38.5%); sepsis (26.6%), severe malaria (15.4%), and nephrotic syndrome (14.8%) were common AKI causes. Fever (72.8%), pallor (52.1%), and vomiting (45.6%) were the most common symptoms. Thirty two (27.8%) patients had high blood pressure. In-hospital mortality was 14.8% (95% CI: 9.8, 21.1). The cumulative incidence of AKI-related mortality was 93.2 per 1,000 person years. Poor outcome was associated with breathlessness, hyponatremia, and leukocytosis. Kaplan-Meier survival curve showed 81% (CI: 74–87%) survival after 5 years of AKI. On Cox proportional-hazards analysis, the absence of breathlessness (HR: 2.537, 95%: CI 1.210–5.317) and hyponatremia (HR: 2.914, 95% CI: 1.343–6.324) were associated with increased survival. Conclusion: In resource-limited settings, infectious diseases and nephrotic syndrome are common causes of AKI. Factors associated with mortality include breathlessness and hyponatremiaItem Childhood nephrotic syndrome in Africa: Epidemiology, treatment trends, and outcomes(Elsevier Inc., 2022) Ademola, A. D.; Asinobi, A. O.; Alao, M. A.; Olowu, W. A.Nephrotic syndrome is a common childhood glomerular disease that is associated with massive proteinuria and edema. Children with nephrotic syndrome are at risk of chronic kidney disease, disease-related complications, and treatment-related complications. Patients with frequently relapsing disease or steroid toxicity may require newer immunosuppressive medications. However, access to these medications is limited in many African countries owing to prohibitive cost, the need for frequent therapeutic drug monitoring, and a lack of appropriate facilities. This narrative review examines the epidemiology of childhood nephrotic syndrome in Africa, including trends in treatment and patient outcomes. In most of North Africa, as well as among White and Indian populations in South Africa, the epidemiology and treatment of childhood nephrotic syndrome closely resembles that of European and North American populations. Historically, secondary causes of nephrotic syndrome (eg, quartan malaria nephropathy and hepatitis B−associated nephropathy) were predominant among Blacks in Africa. Over time, the proportion of secondary cases has decreased, along with rates of steroid resistance. However, focal segmental glomerulosclerosis increasingly has been reported among patients with steroid resistance. There is a need for consensus guidelines for the management of childhood nephrotic syndrome in Africa. Furthermore, establishing an African nephrotic syndrome registry could facilitate monitoring of disease and treatment trends, and provide opportunities for advocacy and research to improve patient outcomes.Item Paediatric dialysis at a tertiary hospital in South-West Nigeria: A 4-year report(Karger AG, Basel, 2022) Ademola, A. D.; Asinobi, A. O.; Alao, M. A.; Wade, A. W.Introduction: Dialysis is potentially lifesaving in children with acute kidney injury (AKI) or chronic kidney disease (CKD), but availability is limited in low-income countries and lower-middle-income countries (LMICs). Methods: In the present study, we perform a 4-year study of patients who received peritoneal dialysis (PD) or haemodialysis (HD) at the Paediatric Nephrology Unit of the University College Hospital Ibadan, Nigeria. Subgroup analysis was performed on patients with sepsis or malaria AKI who underwent HD or PD for predictors of in-hospital mortality. Results: A total of 167 children aged 7 days to 18 years, median 7 (interquartile range 3–12) years, (60.5% males) were studied. In total, 129 (77.2%) had AKI, while 38 had CKD. Regarding AKI, 83 children (64.3%) received HD only, 42 underwent PD only, while 4 underwent both HD and PD. Malaria AKI was treated with HD in 43 (51.8%) or PD in 8 (10.5%), while sepsis AKI was treated with HD in 20 (21.4%) or PD in 33 (78.6%). Mortality in AKI was 16.3% overall, 10.8% in children on HD only, and 26.2% in children on PD only. Patients with sepsis AKI had higher mortality compared to patients with malaria AKI (RR 7.96) [1.70–37.37]). Subgroup analysis showed that age, diagnosis, and dialysis modality were not independent risk factors for mortality. The aetiology of CKD was glomerulonephritis in 26 (68.4%): treatment was HD in 36 and PD in 2 with mortality being 26.3%. Conclusions: PD for AKI showed relatively good outcomes in a LMIC. However, funding and support for a formal dialysis program for the management of AKI and CKD are needed.Item Haemodialysis for paediatric acute kidney injury in a low resource setting: experience from a tertiary hospital in South West Nigeria(Oxford University Press, 2016) Asinobi, A. O.; Ademola, A. D.; Alao, M. A.Background: Acute kidney injury (AKI) is an important cause of preventable mortality among children. Management of AKI may require renal replacement therapy (RRT) but access to RRT for children in low resource settings is limited. Our study explored the role of haemodialysis in the management of children with AKI in a low resource setting in terms of aetiology and outcomes. Methods: A review of patients managed in the Paediatric Nephrology Unit, University College Hospital Ibadan, South-West Nigeria, who underwent haemodialysis for AKI from January 2006 to December 2014. Results: Sixty-eight patients (55.9% males), aged 3–16 (mean ± standard deviation, 9.0 ± 3.4) years were studied. The causes of AKI were sepsis (22.1%), malaria (17.6%) and glomerulonephritis (17.6%), intravascular haemolysis—cause unknown (16.2%), G6PDH deficiency (7.4%), malignancy (8.8%) and haemoglobinopathy (5.9%). The number of sessions of haemodialysis ranged from 1 to 10 (mode = 2 sessions) over a period of 1–55 days. Mortality was 27.9% (n = 19) and was related to the aetiology of AKI (P = 0.000): no deaths among patients with intravascular haemolysis or malaria, six deaths among patients with sepsis (40%), six (50%) among the patients with glomerulonephritis, while all the patients with malignancies died. Conclusions: The outcome of haemodialysis for AKI in Nigeria is relatively good and is related to the underlying aetiology of AKI. In addition to peritoneal dialysis, intermittent haemodialysis may have a role in the management of paediatric AKI in low resource settings and should be supported.
