RESUMO
Chronic kidney disease (CKD) has a high prevalence in Cameroon and will become an important public health problem. Its management must be comprehensive, starting with CKD prevention to the implementation of renal replacement therapies best suited to the needs of patients and resources available in Cameroon. Practical interventions involving nephrology departments in both Africa and Europe can contribute to an improved management of CKD in Africa. The current collaboration between the Geneva University Hospitals and the Yaoundé teaching hospitals is a convincing example. It includes a clinical trial on the treatment of metabolic acidosis linked to CKD, assistance with the placement of hemodialysis catheters by sonography and the initiation of a kidney transplantation program with living donors.
La maladie rénale chronique (MRC) a une haute prévalence au Cameroun et va devenir un important problème de santé publique. Sa prise en charge doit être globale, partant de la prévention de la MRC jusqu'à la mise en place des techniques de suppléance extrarénale les plus adaptées aux besoins des patients et aux ressources disponibles localement. Des actions concrètes, dans le cadre d'une néphrologie solidaire, impliquant des services de néphrologie d'Afrique et d'Europe, peuvent y contribuer. La collaboration entre les Hôpitaux universitaires de Genève et ceux de Yaoundé en est un exemple probant, avec la mise en place d'un essai clinique sur le traitement de l'acidose métabolique liée à la MRC, une aide à la pose des cathéters de dialyse par sonographie et l'initiation d'un programme de transplantation rénale avec des donneurs vivants.

BACKGROUND: A relationship exists between birth weight (BW) and glomerular filtration rate (GFR) in postnatal kidney. Willing to fill a gap of knowledge in sub-Saharan Africa, we assessed the effect of BW on blood pressure (BP), proteinuria and GFR among Cameroonians children. METHODS: This was a cross-sectional hospital-based study from January to April 2018 at the Yaounde Gynaeco-Obstetric and Paediatric Hospital (YGOPH). We recruited low BW (LBW) [< 2500 g], normal BW (NBW) [2500-3999 g] and high BW (HBW) [> 4000 g] children, aged 5-10 years, born and followed-up at YGOPH. We collected socio-demographic, clinical (weight, height, BP), laboratory (proteinuria, creatinine), maternal and birth data. The estimated GFR was calculated using the Schwartz equation. RESULTS: We included 80 children (61.2% boys) with 21 (26.2%) LBW, 45 (56.2%) NBW and 14 (15.5%) HBW; the median (interquartile range) age was 7.3 (6.3-8.1) years and 17 (21.2%) were overweight/obese. Two (2.5%) children, all with a NBW (4.4%), had an elevated BP whereas 2 (2.5%) other children, all with a LBW (9.5%), had hypertension (p = 0.233). Seven (8.7%) children had proteinuria with 19, 2.2 and 14.3% having LBW, NBW and HBW, respectively (p = 0.051). Equivalent figures were 18 (22.5%), 14.3, 24.2 and 28.6% for decreased GFR, respectively (p = 0.818). There was a trend towards an inverse relationship between BW and BP, proteinuria and GFR (p > 0.05). CONCLUSION: Proteinuria is more pronounced in childhood with a history of LBW and HBW while LBW children are more prone to develop hypertension. Regular follow-up is needed to implement early nephroprotective measures among children with abnormal BW.

Chronic kidney disease of unknown etiology (CKDu) is an emerging entity in the South Asian region. This predominately affects the farming community belonging to the lower socioeconomic status. CKDu being a progressive condition often leads to end-stage renal failurerequiring renal replacement therapy (RRT). Due to the high cost and limited availability of RRT in many areas of geographical locations in India and worldwide, there is an unmet need to slow down the progression of CKDu. The intestinal microbiota is different in patients with CKD, with low levels of beneficial bacteria such as Lactobacillus and Bifidobacteria. Prebiotics and probiotics modify the intestinal microbiota and thereby slow down the progression. Soda bicarbonate therapy is cheap and cost-effective in slowing down the progression of CKDu in a subset of patients. There is also evidence of the beneficial effect of N-acetyl cysteine in early stages of CKD and it should benefit CKDu also. Dietary interventions to prevent dehydration, by providing uncontaminated drinking water, sufficient protein containing diet with adequate calories, and tailored salt intake to prevent hypotension, are necessary compared to other causes of CKD. The objective is to prevent malnutrition, and uremic symptoms. Early diagnosis and prompt intervention may delay the progression of CKDu in the early stages.
RESUMO
Although total confinement has not been adopted by the government of Cameroon, the COVID-19 pandemic is keeping geriatric patients out of hospital, despite a decline in their health status. In addition, the pandemic might have a significant effect on their general well-being. This study aimed to examine the effects of the COVID-19 pandemic on the follow-up and well-being of older outpatients seen at geriatric consultation in Cameroon. We carried out a telephone survey of patients who did not attend an appointment at our geriatrics outpatient clinic on April 2020. Overall, 30 participants were recruited of whom 70% were female (n = 21) with a median age of 74 years (IQR 68.8-85). Most patients (73%, n = 22) did not attend their appointment because of fear of being infected by SARS-CoV-2 at hospital. Approximately 23% (n = 7) of participants reported a decline of their functional status since the last geriatric visit. Loss of appetite and weight loss were both reported in 30% (n = 9) of patients. Half of participants (n = 15) self-rated their health status as bad and three of them died in private health facilities. Strategies to ensure a continuum of care for this vulnerable population during this pandemic are highly needed in our setting.
RESUMO
A 51-year-old female, with non-alcoholic liver cirrhosis, portal hypertension, type 2 diabetes mellitus, autosomal dominant polycystic kidney disease with a clipped cerebral aneurysm and chronic kidney disease stage 5 was on continuous ambulatory peritoneal dialysis (CAPD) for 6.5 years elsewhere. She came for opinion on continuation of CAPD as she had 21 episodes of peritonitis in 76 months. Her blood pressure was 80/50 mmHg. She was on haemodialysis with a temporary central access for 2 weeks. She had no abdominal tenderness, and exit site looked normal. Fluid was negative for Mycobacterium tuberculosis. Laparoscopically, we replaced the catheter with a new swan-neck Tenckhoff double-cuff catheter through a different exit site in the same sitting. Catheter-tip biofilm culture isolated Enterococcus casseliflavus. Peritoneal sampling biopsy showed evidence of fibrosis. She has adequate ultrafiltration and is currently on automated peritoneal dialysis for 5 months.

Atypical mycobacteria remain a rare cause of peritoneal dialysis catheter-related tunnel infection (TI) and poses serious risk because of the resistant nature to most antibiotic therapy. Non-tubercular mycobacterial infections lead to chronicity requiring peritoneal dialysis catheter removal. We report an 82-year-old male, with diabetic nephropathy who had a coinfection with Staphylococcus hominis and Mycobacterium abscessus who presented with pus discharge at exit site and TI. He was treated with relocation of the extraperitoneal part of the catheter with a new exit site without catheter removal and multidrug mycobacterial therapy.
