Comparative study of community acute kidney injury in young patients versus elderly patients in an internal medicine department in Abidjan (Côte d’Ivoire)

Introduction: numerous studies have shown that the recovery of renal function was slower and less complete in the elderly patients than in adults.objectives: to compare the profile of acute kidney injury (aki) of the young patients with that of the elderly patients.patients and methods: this is a prospective study carried out during the period from january 2010 to december 2015 in the department of nephrology-internal medicine of the university hospital of treichville. the diagnosis of aki was retained according to kidney disease: improving global outcomes (kdigo) criteria.results: the mean age of patients was 26.8 ± 6 years in the young and 69.4 ± 7 years in the elderly. the proportion of males was 51.9% (55/106) in the young patients against 77.8% (84/108) in the elderly patients (p = 0.0001). the proportion of hypertension and diabetes in the elderly patients, respectively 30.6% and 36.1% was statistically higher than in the young patients (p = 0.001). however, human immunodeficiency virus (hiv) infection was more prevalent in the young patients (p = 0.0001). anemia was observed in 84.9% in the young patients against 58.3% in the elderly patients (p = 0.001). it was severe in 34% among the young patients against 15.7% among the elderly patients (p = 0.002). the proportion of drug aki was 17% in the young patients against 2.8% in the elderly patients (p = 0.0001). malignant hypertension (p = 0.002) and urinary tract tumors (p = 0.001) were more observed in the elderly patients. mortality was 31.1% in the young patients against 47.2% in the elderly patients (p = 0.011).conclusion: the etiologies are the same with different proportions, except malignant hypertension observed only in the elderly patients. mortality is higher in the elderly patients.
