Abstract

Abstract: Background and Aims: Acute kidney injury (AKI) is common in the elderly due to physiologic renal aging and underlying pathologies. Few studies focused on AKI in Tunisian elderly. The aim of our study was to highlight the epidemiological, clinical, etiological, therapeutic, and progressive characteristics of AKI in elderly. Method: We conducted a descriptive retrospective study of AKI in patients admitted to our department over a period of 04 years from 01/01/2014 to 31/12/2017. Results: We collected 40 patients including 25 women and 15 men with a sex ratio of 1.66. The mean age was 74 [65-87] years. We noted the presence of pre-existing chronic kidney disease in 58% of cases, diabetes in 50% of cases and hypertension in 73% of cases. Polypharmacy was found in 40% of cases. AKI was symptomatic in 80% of cases and found on a routine check-up in 20% of cases. Mean creatinine was 612+/-334 µmol/l. AKI was pre-renal in 37% and parenchymal in 63% of cases. Iatrogenic origin was found in 33% of cases. Renal biopsy was performed for diagnostic purposes in 6 cases. Haemodialysis was necessary in 50% of cases. Etiopathogenic treatment was initiated in 73% of cases. Intra-hospital mortality was 10%, recovery of renal function (RF) was partial in 40 % of cases and total in 20 % of cases. Follow-up time was 16 +/- 23.2 months. And at the last news, recovery of renal function (RF) was partial in 7 cases and total in 10 cases, 6 patients kept a chronic renal failure (CRF), among them 3 cases had and end-stage of CRF. Conclusion: AKI is a frequent pathology in the elderly and its severity is linked to mortality and the transition to chronicity. Iatrogenic causes are frequent and preventable in this population, hence the major interest of prevention.
