There is little data on the future of NS in children in sub-Saharan Africa, particularly Cameroon. The aim of our study is to report the prognosis of children treated for nephrotic syndrome in the city of Yaoundé. Method: This was an analytical cross-sectional study with retrospective collection in 4 reference hospitals in the Cameroonian capital over a period of five years from January 1, 2018 to December 31, 2022. We included all medical records of patients treated for idiopathic INS. We excluded incomplete records and those with a history of chronic kidney disease. The sociodemographic, clinical, paraclinical, and therapeutic data, as well as the short-term evolution were collected in the files. Data was analysed using the software statistical package for social sciences version 25.0. Statistical significance was set at a p-value Results: A total of 131 children (58% boys) were included in our study over a period of 5 years. The median age was 8 [6 - 11] years. Median proteinuria was 5 g/24h [3 - 8.4], median serum protein was 39 [34 - 46] g/l and median estimated glomerular filtration rate was 130.36 [68 - 174.6] ml/min/1.73m2. During steroid therapy, 45.07% were in partial remission at 2 months, 16.9% were in complete remission at 4 and 6 months, and 37.25% had relapsed. Steroid sensitivity was reported in 28.17% of cases, steroid resistance in 64.78% of cases and steroid dependent in 7.04% of cases. The mortality rate was 12.97%. Survival time averaged 48.2 months, with an overall crude survival rate of 99.2% at 3 and 6 months and 98.4% at 1 year. Regarding renal survival, renal function was impaired in 8.33% of patients at 6 months and 9% at 12 months. Conclusion: Idiopathic nephrotic syndrome is a common disease in children. Its evolution depends on corticosteroid therapy. The long-term prognosis is dominated by the risk of progression to end-stage kidney disease or even death. Rigorous and affordable follow-up is essential to reduce the number of patients lost to follow-up and the occurrence of complications.展开更多

In sub-Saharan Africa (SSA), AKI is community-acquired occurring in healthy young adults. We aimed to identify predictors of fatal outcomes in patients with AKI in two tertiary hospitals in Cameroon. Methods: Medical records of adults with confirmed AKI, from January 2018 to March 2020 were retrieved. The outcomes of interest were in-hospital deaths and presumed causes of death. We used multiple logistic regressions modeling to identify predictors of death. The study was approved by the ethics boards of both hospitals. Values were considered significant for a p-value of 0.05. Results: We included 285 patient records (37.2% females). The mean (SD) age was 50.1 (19.0) years. Hypertension (n = 97, 34.0%), organ failure (n = 88, 30.9%), and diabetes (n = 60, 21.1%) were the main comorbidities. The majority of patients had community-acquired AKI (78.6%, n = 224), were KDIGO stage 3 (88.8%, n = 253), and needed dialysis (52.6%, n = 150). Up to 16.7% (n = 25) did not receive what was needed. The in-hospital mortality rate was 29.1% (n = 83). Lack of access to dialysis (OR = 27.8;CI: 5.2 - 149.3, p = 0.001), hypotension (OR = 11.8;CI: 1.3 - 24.8;p = 0.001) and ICU admission (OR = 5.7;CI: 1.3 - 24.8, p = 0.001) were predictors of mortality. The presence of co-morbidities or underlying diseases (n = 46, 55%) were the main causes of death. Conclusions: In-hospital AKI mortality is high, as in other low- and middle-income economies. Lack of access to dialysis and the severity of the underlying illness are major predictors of death.展开更多

Objective: Describe the epidemiological and clinical profiles of CKD patients starting HD in emergency. Methodology: This was a retrospective cross-sectional study. Files of patient files of CKD patients who underwent dialysis from January 1<sup>st</sup>, 2016 to December 31<sup>st</sup>, 2020 were reviewed at the HD centres of the two main hospitals of the Cameroon city capital, Yaoundé. We included all emergency HD for End Stage Renal Disease (ESRD). Socio-demographic and clinical data including past medical history, signs and symptoms at presentation and indications for emergency HD were recorded. Emergency HD was defined as a dialysis session performed in ESRD with a temporary vascular access. Data were analyzed using Statistical Package for Social Sciences (SPSS) software version 26 for Windows. Results: Out of 700 recorded CKD patients who started HD, 570 underwent an emergency HD, thus a prevalence of 81.43%. We included 311 patients, 63.7% were males. The mean age was 47.05 ± 15.60 years ranging from 8 to 83 years with a modal age group of 40 - 59 years. The most prevalent co morbidities were hypertension (66.2%), diabetes mellitus (28.6%) and HIV infection (10%). The commonest presenting symptoms were asthenia (68.2%), lower limbs swelling (52.1%) and anorexia (41.8%) and the main clinical signs were high blood pressure (74.92%), and pallor (60.5%) and altered general state (55%). The indications for emergency HD were dominated by uremic encephalopathy (33.4%) and pulmonary oedema (25.7%). Conclusion: More than eight out of ten CKD patients start emergency HD. Patients are mostly middle-aged adults with a male predominance. Hypertension and diabetes mellitus remain the most common co morbidities and uremic encephalopathy is by far the first indication for emergency HD.展开更多

However, limited data are available about its prevalence in sub-Saha-ran region. The aim of this study was to assessed sleep quality and its predictors among hemodialysis patients. Methods: We conducted a cross sectional study of 2 weeks in the Douala General Hospital hemodialysis center of Cameroon involving 46 chronic hemodialyzed patients for at least six months with arteriovenous fistula. Quality of sleep was measured using the Pittsburgh Sleep Quality Index (PSQI) and laboratory data were collected in patients’’ fields. Result: Thirty-five (76.1%) subjects reported poor sleep quality. The most frequent abnormal sleep components were subjective sleep quality, sleep disturbances and sleep latency (87%, 85% and 76% respectively). In univariate linear regression, hemoglobin level, sleep quality, sleep latency, sleep duration, habitual sleep efficiency and sleep disturbance were associated with poor sleep quality. In multivariate linear regression only hemoglobin level (p = 0.004) and sleep latency (p = 0.002) were associated with poor sleep quality. Conclusion: Poor sleep quality is frequent in our hemodialysis patients and hemoglobin seems to be a good predictor of sleep quality in these patients.展开更多
