Pediatric Renal Admission: Clinical Spectrum and Outcome, the Experience of Two Semi-urban, Secondary Hospitals in Cameroon

Background and aim: There is limited data on renal diseases in paediatric admissions in Cameroon. The aim was to describe the clinical spectrum and outcomes of renal diseases among admitted children in two regional hospitals in Cameroon.   Materials and Methods: we reviewed archived records of children admitted with renal disease from the 1st January 2017 to 31st December 2019 for renal diseases and outcomes. Results: In all, 148 (1.98%) of the 7457 admitted children had a renal disease. Their median age was 7.5 years (IQR 4-12) and 63.5% were females with 32.4% less than 5years. Urinary tract infection (51.4%), Acute kidney injury (21.6%), Nephrotic syndrome (12.2%), chronic kidney disease (12.2%) and renal mass (2.6%) were frequently described. Complicated UTI was observed in 9.2% of children with UTI whereas initiation of corticotherapy (83.3%) was the most common reason for admission in children with nephrotic syndrome. Malaria (40.6%) and sepsis (40.6%) were the most common aetiology of AKI whereas chronic GN was the most common aetiology of CKD. Out of the 32 children with AKI, 50% had an indication for dialysis with 87.5% having access to the therapy. Nine (75%) of the 12 children with non-dialysed CKD-5 needed dialysis with 55.5% (5/9) having access to it. Out of the 148 children, 07 (4.7%) died. Deaths were due to AKI and CKD; with specific death rates of 12.5% and 16.7% respectively.   Conclusion: Renal diseases are uncommon among admitted children. Overall in-hospital mortality was low

Survival in elderly patients with kidney failure starting haemodialysis in Cameroon

Introduction: Elderly patients have an increased risk of kidney failure due to ageing and comorbidities. This study assessed survival among elderly patients starting maintenance haemodialysis at the Buea and Bamenda regional hospitals in Cameroon. Methods: We conducted a retrospective cohort study of elderly patients (65 years of age and older) who began maintenance haemodialysis between January 2016 and December 2020. The primary outcome of interest was survival at one year. Results: The proportion of elderly patients starting dialysis was 11%. There were 81 patients included in the study. Their median age at dialysis initiation was 70 years [interquartile range (IQR) 66–73 years] and 90% had high comorbidity scores according to the Charlson Comorbidity Index. The median survival time was 7.5 months (IQR 0.7–12.0 months) and the survival rate at one year was 41%. The most common causes of death were sudden death (42%), infection/sepsis (21%) and dialysis withdrawal (17%). The lowest survival time (median 6.5 days) was observed in patients older than 85 years, with a high comorbidity index. Emergency start to dialysis [hazard ratio (HR) 1.434, P = 0.032), age ≥75 years (HR = 19.384, P = 0.001), refractory hyperkalaemia as an indication for starting dialysis (HR = 1.244, P = 0.02) and high comorbidity index (HR = 2.819, P = 0.014)] were associated with poorer survival. Conclusions: Only half of the elderly patients were still alive one year after starting maintenance haemodialysis. Comorbidity score, age, refractory hyperkalaemia and emergency start to dialysis were associated with survival

Incidence, risk factors, and outcomes of acute kidney injury among hiv positive medical admissions at the Bamenda Regional Hospital

Background: There is a paucity of data on the burden of acute kidney injury (AKI) in hospitalized HIV-infected patients in Sub-Saharan Africa in the “test and treat” era.Objectives: To study the incidence, risk factors, and outcomes of AKI among HIV-positive medical admissions in a secondary hospital.Materials and methods: We prospectively screened adult HIV-positive patients who gave their informed consent and were admitted to the Bamenda Regional Hospital for AKI from February to June 2020. We excluded participants with Chronic Kidney Disease (CKD) Stage 5 and those with confounders of serum creatinine. On admission and after 2-7 days, we extracted a venous blood sample from each participant to evaluate serum creatinine and diagnose AKI. The participants were then followed up on until they were discharged or died. We measured the need for dialysis, access to dialysis, and renal recovery at three months for patients with AKI. The amended KDIGO 2012 criteria were used to define and classify AKI. The University of Bamenda’s institutional review board provided ethical approval.Results: A total of 206 participants (39.8% men) were enrolled, with a mean (SD) age of 45.71(13.13) years. On enrolment, 89.8% (n = 185) of the participants were on combination antiretroviral therapy (c-ART), with 81.6% (n = 151) on tenofovir-containing regimens. The WHO HIV clinical stages 3 and 4 were present in 81.5% (n = 168) of the individuals. The most common reason for hospitalization was opportunistic infections (69.8%; n = 142). AKI was found in 30.6% (n = 63) of the patients, with 58.7% (n = 37) of them being classified as KDIGO stage 3. A total of 12 (42.9%) participants out of the 28 in need, were dialyzed. AKI was independently associated with use of traditional medicines (aOR = 2.9; 95% CI 1.4-6.3; p = 0.006), WHO HIV stages 3 and 4 (aOR = 4.1; 95% CI 1.1-15.7; p = 0.038), hypotension (aOR = 3.3; 95% CI 1.4-7.8; p = 0.008) and low haemoglobin level ≤ 8.0 g/dl (aOR = 3.5; 95% CI 1.7-7.4; p = 0.001). The AKI group used to have a significantly higher mortality rate (42.9% vs. 16.1%; p < 0.001). Renal recovery was complete in 66.7% of the 30 survivors at three months, partial in 13.3%, and no recovery in 20% of the survivors.Conclusion: Despite the growing use of combination antiretroviral medication, significant immunosuppression is still common in hospitalized HIV-positive patients, increasing the risk of AKI and worsening prognosis. In this high-risk population, early detection of AKI with renal function monitoring may improve results

Epidemiological factors associated with HBV infection and uptake of testing in south west region of Cameroon: What can be done to scale up HBV testing in our setting?

Hepatitis B infection affects millions of people globally, partly due to its high degree of transmissibility and asymptomatic nature. This study was aimed at identifying prevailing epidemiological factors associated with HBV infection and testing uptake in the South West region of Cameroon. This hospital-based case-control study enrolled HBV infected participants and "healthy" controls ≥18 years old. Venous blood collected from participants was used to conduct HBV panel test (HBsAg, anti-HBs, HBeAg, anti-HBe, anti-HBc). Data on demographic and behavioral risk factors as well as reasons for taking the HBV test for the first time were collected using a questionnaire. A total of 424 participants were enrolled (212 "healthy" controls and 212 HBV infected cases). Male sex (odds ratio [OR] = 2.08, p = 0.010), ≤ secondary education level (OR = 4.83, p<0.001), low-income level (OR = 3.79, p<0.001), rural settlement (OR = 2.17, p = 0.031), history of sexually transmitted infections (STI) (OR = 4.24, p<0.001) and ignorance of sexual partners HBsAg status (OR = 2.70, p = 0.003) all had an independent and significant association with HBV infection. Top 3 reasons for doing HBsAg test were free screening (40.3%), blood donation (15.0%) and administrative requirements (14.9%). HBV testing uptake and early detection can be improved if more sensitization and free/opportunistic screenings are implemented. A significant drop in the cost of HBV test could encourage more people to get tested
