At the end of 2003, about 1.1 million people were suffering from End-Stage Renal Disease (ESRD) and were treated with periodic dialysis [12]. In Africa, CKF represents 2% to 10% of hospital admissions and is responsible for 4% to 22% of deaths [14]. So, this study is conducted for the first time in Chad, with the aims to determine the prevalence of CKD. Methods: This was a retrospective, descriptive and analytical study over a period of 12 months from April 29, 2011 to April 28, 2012. All patients with chronic renal failure regardless of etiology and stage of chronic kidney disease were included in the study. Chronic renal failure was defined as a glomerular filtration rate below 60 ml/min/1.73m (MDRD) for more than 3 months. This study was conducted in several departments of the National General Reference Hospital (NGRH) of N’Djamena. Result: Among 2039 inpatients, 195 patients had chronic renal failure, as a frequency of 9.6%. The average age of our patients was 51 ± 16.8 years, ranging from 11 to 85 years. Male predominance was noted to be 59% of men against 41% of women. We noted that high blood pressure accounted for 66.2% (N = 129) of cases, diabetes in 48.2% (N = 94), alcoholism in 28.7% (N = 56), smoking in 14.9% (N = 29) and the association alcoholism-smoking in 19.5% (N = 38). Hypertension was the leading cause of chronic renal failure (66.2%). All patients had a serum creatinine and creatinine clearance was assessed. Among them, we noted 57 patients (29%) with end-stage renal failure. The average calcium and phosphate serum were 1.8 mmol/l and 1.6 mmol/l, respectively. We noted that 120 patients as 61.5%, currently took herbal medicine. 48 out of 57 of our patients with ESRD as 24.6% of patients in the study had received replacement therapy (hemodialysis) with 12.5% of deaths. Conclusion: Chad, who compiled the first study with 195 patients at the General Hospital of N’Djamena National Reference over a period of one year has objectified a prevalence of chronic renal failure of 9.6%.展开更多
Introduction: Hyperuricemia is defined as a level of serum uric acid greater than or equal to 70 mg/l (420 μmol/l) in men and 60 mg/l (360 μmol/l) in women.

Several studies have shown that it is a risk factor or a factor of progression of chronic kidney disease. Recent experimental and epidemiological data correlate the association of hyperuricemia with chronic kidney disease (CKD), arterial hypertension and cardiovascular diseases, thus raising the question of the usefulness of therapeutics in the prevention of renal diseases. The objective of this study is to seek a link between chronic kidney disease and hyperuricemia. Materials and Methods: This is a descriptive and analytical study conducted at hemodialysis unit and cardiology service of General Hospital of National reference of N’Djamena (Chad) from 1th January to 1th October 2013 (10 months). We included all chronic kidney disease patients hospitalized in hemodialysis unit and cardiology service who presented associated hyperuricemia. Results: There were 712 CKD patients who were hospitalized. Among them, there were 108 patients who were included in the study and who had hyperuricemia as a prevalence of 15.20%. The average age of patients was 35.5 years and the sex ratio was 3/1. The age group between 40 to 60 years represented 54.6%. There were 41.7% of traders. Hypertensive patients accounted for 49.1%;association of diabetes and hypertension was noted in 12.90%. Renal insufficiency was moderate in 43.5% of patients. Hyperuricemia was present in more than 90% of patients. Profession, age, hematuria, proteinuria and hypertension were statistically positively related to hyperuricemia. Treatment consisted of prescribing allopurinol in 84% of patients. In more than 11% of patients the progression was unfavorable. Conclusion: The implication of hyperuricemia in chronic kidney disease has been proved in several recent studies. However, randomized studies at very long scales have to be carried out to conclude from its real impact on the prevention and treatment of chronic kidney disease.展开更多

In children, studies of ARF during malaria are limited. We have no published studies on this topic in Niger. The main objective of our study is to evaluate the prognosis of ARF during severe malaria in children. Patients and Method: This is a one-year prospective study (January 1, 2016 to December 31, 2016) conducted in the resuscitation unit of the pediatric department of the National Lamordé Hospital of Niamey (Niger). We included in the study children aged 0 to 15 years hospitalized for severe malaria with impaired renal function. Patients who had chronic renal failure or who had acute renal failure with a thick negative drop were excluded from the study. Acute renal failure is defined according to Kidney Disease Improving Global Outcomes (KDIGO) criteria basing on creatinine clearance. Results: The incidence of ARF was 12.60%. The mean age of the patients was 4.25 ± 1.3 years [8 months - 15 years]. The mean hemoglobin level was 8.2 ± 2.7 g/dl. In 54.02% of cases, the hemoglobin level is ≤5 g/dl. Mean serum creatinine was 543.7 ± 69.5 μmol/l [107 - 2500 μmol/l] and mean azotemia was 27.5 ± 3.5 mmol/l. Severe anemia (54.02%) were more related to the occurrence of ARF(with p = 0.014). According to the RIFLE classification, 55 patients (63.22%) were in the Risk stage, 18 patients (20.69%) were in the injury stage and 14 patients (16.09%) in the failure stage. All patients were placed on injectable Artesunate. The average length of hospital stay was 8.6 ± 4.5 days [5 to 22 days]. Dialysis was reported in 15/87 (17.24%). For technical and financial reasons only 8 patients were hemodialysed. Indications for dialysis were severe uremic syndrome 7 cases (8.04%), fluid overload 5 cases (5.75%) and severe hyperkalemia 3 cases (3.45%). Conclusion: The etiological factors of ARI in malaria were massive hemoglobinuria, severe anemia and shock. Adequate management of simple cases of malaria and the early transfer of severe cases to resuscitation services can prevent certain complications such as acute renal failure.展开更多
