Bi- and Monoallelic Variants and Chronic Kidney Disease in West Africans.

Background: Apolipoprotein L1 gene () variants are risk factors for chronic kidney disease (CKD) among Black Americans. Data are sparse on the genetic epidemiology of CKD and the clinical association of variants with CKD in West Africans, a major group in the Black population.

Methods: We conducted a case-control study involving participants from Ghana and Nigeria who had CKD stages 2 through 5, biopsy-proven glomerular disease, or no kidney disease.

Factors Associated with Mortality and Long-Term Outcomes of Pediatric Acute Kidney Injury in a Resource Limited Setting.

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, inhospital mortality, and long-term outcomes in resource-limited settings.

Methods: This was a prospective study of children with AKI from 2014 to 2019.

Childhood Nephrotic Syndrome in Africa: Epidemiology, Treatment Trends, and Outcomes.

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.

Precision nephrology identified tumor necrosis factor activation variability in minimal change disease and focal segmental glomerulosclerosis.

The diagnosis of nephrotic syndrome relies on clinical presentation and descriptive patterns of injury on kidney biopsies, but not specific to underlying pathobiology. Consequently, there are variable rates of progression and response to therapy within diagnoses. Here, an unbiased transcriptomic-driven approach was used to identify molecular pathways which are shared by subgroups of patients with either minimal change disease (MCD) or focal segmental glomerulosclerosis (FSGS).

Paediatric Dialysis at a Tertiary Hospital in South-West Nigeria: A 4-Year Report.

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.

HIV Viremia Is Associated With Variants and Reduced JC-Viruria.

Variants in the () gene (G1-rs60910145, rs73885319, G2-rs71785313) are common in Africans and in individuals of recent African ancestry and are associated with an increased risk of non-diabetic chronic kidney disease (CKD) and in particular of HIV associated nephropathy (HIVAN). In light of the significantly increased risk of HIVAN in carriers of two risk alleles, a role in HIV infectivity has been postulated in the mechanism of associated kidney disease. Herein, we aim to explore the association between HIV viremia and genotype.

Acute kidney injury among paediatric emergency room admissions in a tertiary hospital in South West Nigeria: a cohort study.

Background: Epidemiological data on paediatric acute kidney injury (AKI) in sub-Saharan Africa are limited and largely retrospective. We performed a prospective study of AKI among patients admitted through the emergency room.

Methods: Children admitted to the post-neonatal emergency room of the University College Hospital, Ibadan, Nigeria between February 2016 and January 2017 were studied.

Kidney disease in hepatitis B surface antigen-positive children: experience from a centre in south-west Nigeria and a review of the Nigerian literature.

Background: Kidney disease is an important extra-hepatic manifestation of hepatitis B virus (HBV) infection. However, there is paucity of recent literature on kidney disease in children and adolescents with HBV infection from several parts of sub-Saharan Africa including Nigeria.

Objective: To review the pattern of kidney disease in hepatitis B surface antigen (HBsAg)-positive children and adolescents seen at a tertiary hospital in south-west Nigeria.

Haemodialysis for paediatric acute kidney injury in a low resource setting: experience from a tertiary hospital in South West Nigeria.

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.

Trends in the histopathology of childhood nephrotic syndrome in Ibadan Nigeria: preponderance of idiopathic focal segmental glomerulosclerosis.

Background: Reports on the histopathology of childhood nephrotic syndrome (NS) had emanated from our Centre since the 1960s and by the late 1980s and early 1990s, a change was observed and reported. Taking into consideration the worldwide changing trend in the histopathology of the NS and our Unit policy change in the indications for renal biopsy, a change was envisaged. We therefore evaluated the current histologic pattern of childhood NS in Ibadan with the view to highlighting any variations from the past and comparing the findings with regional and global trends.

Factors Associated with Medication Nonadherence among Hypertensives in Ghana and Nigeria.

Background. Blood pressure (BP) control is poor among hypertensives in many parts of sub-Saharan Africa. A potentially modifiable factor for control of BP is medication nonadherence (MNA); our study therefore aimed to determine factors associated with MNA among hypertensives in Ghana and Nigeria.

Plasma homocysteine and B vitamins levels in Nigerian children with nephrotic syndrome.

Introduction: Available data on plasma homocysteine level in patients with nephrotic syndrome (NS) are controversial with increased, decreased and unchanged values reported. Therefore, plasma homocysteine and serum B vitamins in Nigerian children with NS were assessed in this study.

Methods: Fasting blood samples were analysed for plasma homocysteine, serum folate and B vitamins in 42 children with NS and 42 age and sex-matched healthy controls in this case control study.

Paediatric end-stage renal disease in a tertiary hospital in South West Nigeria.

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.

Peritoneal dialysis in childhood acute kidney injury: experience in southwest Nigeria.

Background: The choices for renal replacement therapy (RRT) in childhood acute kidney injury (AKI) are limited in low-resource settings. Peritoneal dialysis (PD) appears to be the most practical modality for RRT in young children with AKI in such settings. Data from sub-Saharan Africa on the use of PD in childhood AKI are few.

Diagnosing renal failure due to diethylene glycol in children in a resource-constrained setting.

Background: In 2008, several Nigerian children developed acute kidney injury (AKI) after ingesting teething syrup contaminated with diethylene glycol (DEG). Because there are limited diagnostic facilities in resource-constrained countries, this study investigated whether AKI associated with DEG could be identified by other means.

Methods: This was a multicenter study.
