Abstract
Background: The burden of acute kidney injury (AKI) is high in Africa. While there are no reliable statistics about AKI in Africa, the Global Snapshot Study of the 0by25 initiative of the International Society of Nephrology has determined dehydration, infections, animal envenomation, and complications during pregnancy as the main causes. Methods: This study was conducted at the Soba University Hospital (SUH), Khartoum, Sudan, a tertiary referral center. We included all hemodialysis patients treated for AKI at SUH between January 1, 2013 and December 31, 2014 in the study. We reviewed patients’ hospital records and characterized pathogenesis, treatment, and patient outcomes. In addition, we investigated survival by Kaplan-Meier and Cox regression analysis. Results: Out of 520 patients who received emergency HD, 71 patients (14%) had AKI (age 40.6 ± 17.3 years, 56.5% were males). Glomerular and tubular-interstitial diseases were the leading cause of AKI, followed by envenomation and intoxication by hair dye. Patients received a median of 5 dialysis sessions for a median of 8 days. In 32 patients (45%) renal function recovered, 10 patients (14%) died, and 29 patients (41%) remained dialysis-dependent. Mortality was significantly higher in females compared to men (hazard ratio 4.1 [95% CI 1.02–16.67]). Outcomes were worse in patients with pre-renal AKI and intoxications. Conclusion: Our results indicate a higher mortality in females and in patients with pre-renal AKI and intoxications. Awareness of factors associating with poor outcomes is central to diagnostic and therapeutic efforts, and must be considered in the design of initiatives to reduce risk factors and improve outcomes of AKI in developing countries.
