[Chronic renal failure and hemodialysis in Lomé: are patients on haemodialysis and their entourage well informed?] / Insuffisance rénale chronique et hémodialyse à Lomé: l´hémodialysé et son entourage sont-ils bien informés?

End stage renal failure requires substitution therapy, including hemodialysis. Before initiation, patients and their entourage receive information on renal disease and treatment options. The purpose of this study is to assess the level of knowledge as well as the opinion of patients on haemodialysis and of their entourage on chronic kidney disease and substitution therapies. We conducted a cross-sectional descriptive study in the Department of Haemodialysis at the Sylvanus Olympio University Hospital (CHU-SO) from 29 July to 19 August 2020. The study population was composed by all the haemodialysis patients in the Department of Haemodialysis at the CHU-SO and by their accompanying persons who gave their free and informed consent. Anonymous survey was used to collect data. Data collection and statistical analysis were carried out using the Epi Info software 7.2.2.6. Eighty-one patients and 79 accompanying persons were interviewed. The average ages of patients and their accompanying persons were 49.7 years ± 13.5 and 39,6years ± 13.2 respectively. All patients knew their disease and 94% of accompanying persons were informed about their parents' disease. Hemodialysis was considered very expensive by 95.1% of patients. Patients stated that improved quality of life was the most known benefit of hemodialysis (80.2%) while 15% also thought that renal transplantation was equally effective. The majority of accompanying persons (85%) stated that hemodialysis was the best treatment. Haemodialysis education program for patients and their accompanying persons is essential to better overall management of haemodialysis patients.

[Renal involvement during monoclonal gammopathies at the teaching hospital of Yopougon in Abidjan, from 2000 to 2016]. / Manifestations Renales des Gammapathies Monoclonales au CHU de Yopougon de 2000 a 2016 : Etude Retrospective D'Une Serie de 42 cas.

BACKGROUND: Renal involvement is common during monoclonal gammopathies and their occurrence impacts the survival of the patients. Our objective was to describe the renal features during monoclonal gammopathies from 2004 to 2016 at the University Hospital of Yopougon in Abidjan. METHODS: Renal failure was defined as blood creatinine level > 20 mg/L and/or proteinuria > 500 mg/24 hours. RESULTS: We identified 42 cases of monoclonal gammopathiesincluding multiple myeloma (n=40) and monoclonal gammopathy of underdetermined significance (n=2). The rate of renal impairment was 57% (n=24) including tubular disease (n=20)and glomerular nephropathy (n=3). Two patients (one with cast nephropathy and another with Randall's disease) performed renal biopsy. The factors associated with renal impairment were mainly hyperuricemia (n=24)and hypercalcemia (n=23). Three cases were treated by hemodialysis. There were 6 (14.3%) deaths among patients with renal impairment. CONCLUSION: Tubular injury was common among patients with monoclonal gammopathy. It was associated with hypercalcemia and Hyperuricemia.

CONTEXTE: Les atteintes rénales sont fréquentes au cours des gammapathies monoclonales (GM) et leur persistance impacte la survie des patients. Notre objectif était de décrire ces atteintes observées de 2004 à 2016 au CHU de Yopougon à Abidjan. MÉTHODES: L'atteinte rénale était définie par une créatinine > 20 mg/l et ou une protéinurie > 500 mg/24 heures. RÉSULTATS: Nous avons recensé 42 cas de GM dont 40 cas de myélome multiple et 2 cas de gammapathie monoclonale de signification indéterminée. La fréquence de l'atteinte rénale était de 57% (n=24). Il s'agissait de 3 cas de néphropathie glomérulaires et 20 cas d'atteintes tubulaires. Deux patients ont bénéficié d'une ponction biopsie rénale et c'était un cas de tubulopathie myélomateuse, et un cas de maladie de Randall. Les facteurs favorisant l'atteinte rénale étaient dominée par l'hypercalcémie (23 cas) et l'hyperuricémie (24 cas). Trois cas ont été traités par hémodialyse conventionnelle. Il y eu 6 (14,3%) décès parmi les patients ayant l'atteinte rénale. CONCLUSION: l'atteinte tubulaire est plus fréquente au cours de la gammapathie monoclonale. Elle est favorisée par la prise de toxiques traditionnels, l'hypercalcémie et l'hyperuricémie.

[Purple urine-bag syndrome: A case report]. / Le syndrome de la poche à urines violette : à propos d'un cas.

Purple urine-bag syndrome is a rare condition that occurs in patients with indwelling urinary catheters carried over a long period and frequently associated with a urinary tract infection. It is characterized by the appearance of a violet coloration of the probe and/or the urine collection bag. We report the first case in West Africa that occurred in a 47-year-old woman in uremic encephalopathy and carrier of a urinary catheter, which presented a violet color of the tubing and urine-bag associated with a urinary tract infection. The outcome was favorable under antibiotic therapy. Many patients benefit from the installation of urinary catheters for various reasons and the occurrence of this syndrome should lead the medical team to systematically seek an underlying urinary tract infection to avoid if possible paraclinical assessments generally costly to our patients without medical coverage in our developing countries.

[Characteristics of potential living kidney donors in Ivory Coast: a survey prior to a project of kidney transplantation in French Black Africa]. / Typologie des potentiels donneurs vivants de rein en Côte-d'Ivoire: une enquête prélude à un projet de greffe de rein en Afrique noire francophone.

The source of living kidney donors in the general population remains underused. The present study aims at assessing the prevalence and the characteristics of potential living kidney donors in Ivory Coast in a view of a project of kidney transplantation in French Black Africa. A survey was undertaken in Abidjan from 30 June to 7 July 2006. Nine hundred (and) sixty-two subjects living in the capital and aged between 19 and 64 years old were randomly chosen using data from the 1998 population census. Subjects were asked their age, gender, nationality, marital status, information on kidney graft and renal failure, and their willingness to donate kidney to a relative or friend for transplantation purpose. Seventy per cent of the population study appeared favourable to kidney donation. Potentials living kidney donors have displayed following characteristics: age inferior to 26 years old [OR=2.08, P<0.02, 95%CI: 1.10-3.92]; Ivorians national [OR=2.72, P<0.002, 95% CI 1.42-5.21]; having heard of kidney transplantation (OR=1.89, P<0.047, 95% CI 1-3.54]); the death of a relative or friend from renal failure [OR=1.82, P<0.002, 95% CI 1.25 2.67]. Being married adversely affect kidney donation [OR=0.52, P<0.0002, 95% CI 0.34-0.79]. Potentials living kidney donors are in great number in Ivory Coast, who had specific characteristics.

[Chronic renal failure in sickle cell disease: A retrospective analysis of 100 adults sickle cell patients from black Africa]. / Insuffisance rénale chronique au cours de la drépanocytose : une analyse rétrospective de 100 patients adultes drépanocytaires majeurs d'Afrique noire.

The prevalence of chronic renal failure (CRF) in sickle cell disease (SCD) patients could vary from one country to another depending on the modalities of management. The aim of the present study was to appreciate the epidemiology of CRF in SCD patients from black Africa in order to search for promoting factors. One hundred SCD adult patients have been considered for the study. The glomerular filtration rate (GFR) has been estimated according to the CKD-EPI formula. Three groups of patients have been identified according to the value of their GFR. The mean age of the patients was 30.84±8.26 years. Male gender has represented 51% of the study population. The mean GFR value was 175.4±86.2 mL/min/1.73 m(2). The prevalence of CRF was 11%. About 3% of them had severe CRF. Subjects with normal GFR were 20%. Subjects with glomerular hyperfiltration (HF) were 69%. By univariate analysis, when subjects with HF were compared with those presenting normal GFR, the following factors have appeared to be significantly associated: female gender (female 60.9% versus male 39.1%; P<0.01), weight <60 kg (weight <60 kg; 53.67±9.45 kg versus weight >60 kg; 59.9±9.41 kg; P<0.008), age <30 years (younger age 29.36±7.9 years versus older age 35.14±8.02 years; P<0.001), lower hemoglobin value (9.38±2,3 g/dL versus 10.33±2.61 g/dL; P<0.04). By logistic regression analysis, age <30 years (age >30 years; OR=0.12 [CI95% 0.03-04]; P<0.001), female gender (male gender; OR=0.17 [0.04-0.64]; P<0.01), weight <60 kg (weight >60 kg; OR=0.19 [CI95% 0.05-0.72]; P<0.01) were associated with HF. By univariate analysis, when subjects with CRF were compared with those presenting normal GFR, a lower hemoglobin value was significantly associated with CRF (7.92±2.7 g/dL versus 10.43±2.5 g/dL; P<0.009). There was a trend for subjects not being under maintenance therapy to more experience CRF (36.4% versus 70%; P<0.07). By logistic regression analysis, only a low hemoglobin value was associated to CRF (higher hemoglobin level; OR=0.55 [0.20-6.3]; P<0.01). In total, CRF and HF are frequent complications in SCD adult patients from black Africa.

Characteristics and outcome of living kidney donors after donation: A report from Cote d'Ivoire.

Kidney transplantation from living kidney donors (LKDs) because of its good results represents a good option for the treatment of patients with the end-stage renal disease. Kidney donation is a relatively safe procedure according to several studies. We conducted this cross-sectional study in order to describe the demographic, clinical, and renal outcome of LKD in Côte d'Ivoire. From March to November 2014, LKD residing in Côte d'Ivoire at the time of investigation and having donated the kidney more than one year ago were considered for the study. They were evaluated through a questionnaire. Of the 29 LKD listed in Côte d'Ivoire, only 14 responded to the questionnaire. The mean age at donation was 43.29 ± 9.12 years (27-59) and 10 of the LKD were women. Eight were related to the recipients, and the remaining were spouses. Laparoscopic nephrectomy was performed in nine LKD. The left kidney was harvested in ten cases. The main motivation for donation in all donors was the desire to save a life. At the time of the survey, the average duration after the donation was 4.57 ± 2.56 years (1-8). Only five donors had a regular nephrological follow-up. Hypertension was observed in one donor, seven had significant proteinuria, and six had glomerular filtration rate <60 mL/min but >30 mL/min. Significantly higher proteinuria was noted in donors under 45 years as compared to those over 45 years (0.43 ± 0.17 g/24 h vs. 0.22 ± 0.03 g/24 h, P = 0.01). Our study suggests that renal disease in LKD in Côte d'Ivoire is low after a mean follow-up period of four years. A donor registry is essential to ensure better follow-up of donors in order to detect potential adverse effects of kidney donation in the medium as well as in the long-term.

[Hemorrhagic cystitis due to adenovirus in a renal transplant recipient: the first reported case in black Africa in a setting of a very beginning of a kidney transplantation program and review of the literature]. / Cystite hémorragique à adénovirus chez le transplanté rénal: à propos d'un premier cas en Afrique noire survenu dans un tout débutant programme de greffe rénale et revue de la littérature.

Viral infections are an important complication of transplantation. Polyomavirus are the commonest viruses that infect the renal allograft. Herpes virus nephropathy has also been described. In the past 15 years, adenovirus nephritis has emerged as a potentially life-threatening disease in renal transplant patients in developed countries. Most of the papers devoted to adenovirus nephritis are reported cases. The fate of such patients in resources-limited countries is not known. Herein, we describe the clinical, biological and prognostic findings of a black African transplanted patient with adenoviral hemorrhagic cystitis. This case is the very first of its kind reported in black Africa in a setting of a start of a renal transplantation pilot project. The patient is a 54-year-old man admitted at the nephrology service for gross haematuria and fever occurred 1 month after kidney transplantation. The diagnosis of adenoviral hemorrhagic cystitis has been suspected because the patient has displayed recurrent conjunctivitis and gastroenteritis well before transplantation, which was then confirmed by the real-time polymerase chain reaction performed on the blood. Conservatory measures associated with immunosuppression reduction have permitted the discontinuation of haematuria. This case has been discussed in regard of the epidemiology, the diagnosis, the treatment, the evolution and the prognosis of the adenoviral infection in the renal transplant patient. A review of the literature has been performed subsequently.
