Core Tip
Core Tip: This systematic review of nine studies (6031 patients) found that acute kidney injury (AKI) occurs in 62.9% of acute liver failure (ALF) cases, with incidence varying from 37.9% to 79.1%. Drug-induced ALF, especially paracetamol-related, was the predominant etiology in most cohorts, while viral hepatitis was more common in Asia. Few studies identified independent AKI risk factors, with systemic inflammation, shock, and tumor necrosis factor-alpha elevation among them. AKI was consistently associated with increased mortality and lower transplant-free survival. Significant gaps include a lack of etiological data, pathophysiological insights, and representation from low- and middle-income countries, highlighting the need for standardized definitions and multicenter research.
