Background: Acute kidney injury remains a common complication with a poor prognosis, and is a significant predictor of mortality in cirrhosis patients. We aimed to determine the percentage of acute kidney injury in decompensated cirrhosis patients and evaluate the treatment results of acute kidney injury as well as several factors related to the mortality of decompensated cirrhosis patients. Methods: A prospective study was conducted on decompensated cirrhosis patients in Can Tho City, Vietnam, from 2019 to 2020. Decompensated cirrhosis patients were found to have acute kidney injury on admission by a blood creatinine test. They were treated according to ICA 2015 standards, after which they were monitored and evaluated for treatment outcomes during hospitalization. Results: Of 250 decompensated cirrhosis patients, 64 (25.6%) had acute kidney injury and 37.5% died. Several factors were associated with mortality in decompensated cirrhosis patients, such as Child–Pugh C (p = 0.02; OR = 3, 95% CI 1.5–6.3), acute kidney injury (p p = 0.01; OR = 2.5, 95% CI 1.2–5.1), elevated total bilirubin > 51 µmol/L (p = 0.03; OR = 2.2, 95% CI 1.1–4.6), and prothrombin p = 0.03; OR = 6.8, 95% CI 1–51.6). Hypoalbuminemia was unrelated to mortality in these patients (p = 0.8; OR = 1.2, 95% CI 0.5–2.7), but gastrointestinal bleeding significantly increased mortality in these patients up to 2.3 times (p = 0.03; OR = 2.3, 95% CI 1.1–4.9). Three independent factors regarding mortality in decompensated cirrhosis patients included acute kidney injury, hepatic encephalopathy, and gastrointestinal bleeding. The rate of acute kidney injury in patients with decompensated cirrhosis was 25.6%; the mortality rate was 37.5%. Conclusions: Acute kidney injury was a valuable predictor of mortality in Vietnamese patients with decompensated cirrhosis.
