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 1 th January to 1 th 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 10hyperuricemia. 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.
Introduction:High blood pressure is a major cardiovascular risk factor. In hypertension, noncompliance is frequent. The objective of this work is to evaluate the therapeutic observances and to identify the predictive factors of poor compliances in Chadian hypertensive patients. Patients and Methods:It was a prospective cross-sectional study over a six-month period from January 15 to July 15, 2019. This was performed in the outpatient Cardiology and Nephrology units at the Renaissance Hospital of N'Djamena. We included all follow-up patients who had hypertension who consulted during the study period. However, dialysis patients and children were excluded from this study. The parameters studied were demographic characteristics, economic and therapeutic data and the rate of therapeutic compliance.Results: Eighty-seven patients were included. The average age was 50 years old. The sex ratio was 2.5. Sixty-seven percent (n = 58) of the patients were from urban areas. The predominant cardiovascular risk factors were smoking in 25% (n = 22) and diabetes in 23% (n = 20). Hypertension was uncontrolled in 76% (n = 66) patients. Adherence was poor in 66% (n = 57) of patients. The monthly cost of treatment was respectively 10,000 and 20,000 FCFA in 52% (n = 45) of cases. Combination therapy was observed in 70% of cases (n = 61) and 56% (n = 49) of patients had more than one drug intake. The adherence rate was 93% (n = 28) in the urban population (p < 0.001). All patients (n = 30) who were observing their treatment were educated (p < 0.001). The adherence rate was 20% (n = 6) in patients who had a monthly income less than 100,000 FCFA (p = 0.004). The adherence rate was 60% (n = 18) when the monthly cost was less than FCFA 10,000 (p = 0.003). The adherence rate was 77% (n = 23) in patients receiving monotherapy (p < 0.001). Conclusion:This study showed a low level of adherence in Chadian hypertensive patients. The complexity and cost of antihypertensive therapy, poor knowledge of hypertension, and ignorance of its severity have been the main factors of poor compliance.Compliance of hypertensive patients with antihypertensive drug therapy at the Renaissance Hospital of N'
Introduction: Chronic renal failure is a disease that affects many patients worldwide and increasingly in Africa. 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.
IntroductionLe diabète sucré constitue un véritable problème de santé et ses complications touchent plusieurs organes dont les reins. Un diagnostic précoce de la néphropathie diabétique permet de prendre en charge les patients plus efficacement et de façon multidisciplinaire, de retarder sa progression vers l'insuffisance rénale chronique. Peu d'études ont été faites en Afrique dans ce domaine. Au Tchad, nous ne disposons pas de données statistiques sur l'atteinte rénale liée au diabète. C'est pourquoi nous nous proposons d'étudier la néphropathie diabétique avec pour objectifs d'analyser le profil de la néphropathie diabétique des patients de l'hôpital général de référence nationale de N'Djamena.MéthodesNous avions mené une étude transversale descriptive à l'Hôpital Générale de Référence Nationale de N'Djamena d'avril à septembre 2012. Etaient inclus dans l'étude tous les patients diabétiques hospitalisés ou suivis dans les services de néphrologie et d'endocrinologie.RésultatsIl y avait 54 cas de néphropathie diabétique sur 181 patients soit 29,80%. L'âge de plus de 50 ans représentait 87%, le sexe masculin dominait avec 67%, la durée d'évolution du diabète au moment de la découverte de la néphropathie était de 10,25 ans, la pression artérielle moyenne était de 138 mm Hg, l'HbA1C était supérieur à 6,5% dans 74,5%, l'insuffisance rénale terminale était retrouvée dans 26,90%, une protéinurie à 2,65 g/24 h était détectée dans 60,30%. 57,4% des patients avaient une rétinopathie diabétique au stade III.ConclusionAu Tchad, la fréquence de la néphropathie diabétique est de l'ordre de 29,83%. C'est une affection qui touche les hommes avec une moyenne d'âge de 58,7 ans. Le diabète de type 2 est le plus fréquent avec 90,7% des cas. Les facteurs de risque mal contrôlés pouvaient conduire la néphropathie diabétique vers une altération de la fonction rénale notamment l'HTA (70,8%), un déséquilibre glycémique (66,7%) et une protéinurie (62,5%).
