Objective: Chronic end-stage renal failure is a major public health problem in developing countries and is poorly documented. The objective of this study was to describe the epidemiological, diagnostic, therapeutic, and evolutionary aspects of patients admitted for end-stage renal failure to the Department of Nephrology at the University Hospital of Brazzaville. Patients and Methods: This was a descriptive cross-sectional study collecting prospective data that took place over 10 months. We included 128 patients who were exhaustively identified. Sociodemographic, clinical, therapeutic and developmental data were collected using a standardized and pretested pre-established survey form. The EPI info software enabled the analysis and processing of the data. Results: We reported a male predominance with a sex ratio of 2.5. The median age was 50 years. The first cause found was diabetes (55%) followed by hypertension (46%). The majority of patients had a dialysis emergency and half could not be dialyzed for financial reasons. Conclusion: Our results highlighted that certain epidemiological parameters of end-stage renal failure are constantly changing, such as frequency, while others remain static, including the main etiologies, gender, and age. However, mortality continues to increase and deserves more attention.

Background: Diabetic nephropathy is the leading cause of end-stage chronic kidney disease with poor prognosis in resource-limited settings. This study aimed to determine factors associated with mortality in patients starting dialysis treatment for end-stage chronic renal disease in an emergency context. Patients and Methods: This was a retrospective study from January 2020 to December 2022 at CHU-B. Data from 79 diabetic patients requiring emergency dialysis were compared with those of 79 non-diabetic patients with an end-stage renal disease requiring emergency dialysis. Data were collected from the Nephrology Department registry. We studied their initial clinical and biological profiles and factors related to mortality. Results: Out of 545 compiled records, 79 diabetic chronic kidney disease patients needing dialysis were included (group 1). A control group of 79 non-diabetic chronic kidney disease patients requiring emergency dialysis was also included (group 2). The average age of patients was 53.5 ± 17 years, and the duration of diabetes at dialysis initiation was 14.8 ± 4.3 years. Twenty-three percent were hypertensive. Fifty-two percent of patients experienced intra-dialytic hypotension. Death occurred in 22% of patients. Results show that age (adjusted OR 1.955;CI: 1.025 - 1.086;p-value: Conclusion: Emergency dialysis in diabetics is associated with unfavorable outcomes in terms of mortality. Despite follow-up, renal involvement remains poorly explored, emphasizing the need for physician awareness.

Iron Metabolism Abnormalities in Children with Homozygous Sickle Cell Disease in Brazzaville

Open Journal of Pediatrics 2023年第3期13卷 394-407页

Introduction: Sickle cell disease is the most common genetic disease in the world, particularly in sub-Saharan Africa. It is a protean condition with multiple complications including disturbed iron metabolism. Objectives: To determine the prevalence of iron metabolism abnormalities in children with homozygous sickle cell disease, to describe the epidemiological, clinical and paraclinical characteristics of children with these abnormalities and to identify associated factors. Patients and Methods: This was a cross-sectional analytical study conducted over 9 months in the mother-child consultation unit of the Brazzaville University Hospital, the National Reference Centre for Sickle Cell Disease and the paediatric department of the Blanche Gomes mother-child hospital. It concerned children aged between 3 months and 15 years followed up for homozygous sickle cell disease. The study was based on a haemogram, iron metabolism test, LDH, transaminases and CRP. Results: The overall prevalence of iron metabolism abnomalities was 40.7%. Of the 145 children included, 35.9% had iron overload and 4.8% iron deficiency. Iron overload was associated with infections, undernutrition, iron supplementation and number of blood transfusions. Iron deficiency was not significantly associated with any factor but recurrent infections were relatively more frequent. Conclusion: Abnormalities of iron metabolism in sickle cell patients are relatively frequent, which justifies monitoring during follow-up for early detection and better management. .
