ALB and acute kidney injury: About 92.3% of patients with HRS received intravenous fluids, and 75.4% received intravenous albumin within 48 h of acute creatinine rise. In this study, the mean age was 55.7 ± 0.61, and baseline serum creatinine was 0.94 ± 0.14, with a diverse racial distribution. About 27.2% of patients met the diagnostic criteria for HRS, and HRS patients had the highest in-hospital mortality rate of 41.5%, compared to 14.1% for pre-renal azotemia and 23.3% for acute renal failure (ARF) (P<0.01).
