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.
