Impact of Acute Kidney Injury on Sarcopenia and Frailty in Patients With Liver Cirrhosis

The aim of this prospective study is to collect data on patients with liver cirrhosis and to investigate the impact of acute kidney injury on sarcopenia and frailty in patients with liver cirrhosis. If patients agree to participate in this clinical trial, the patients' data (such as age, sex, height, weight, nutrition status \[RFH-NPT\], history of medication, laboratory findings, endoscopic findings, and radiologic findings) will be collected in a research database. Renal injury was measured using conventional and novel serum biomarkers (serum creatinine, cystatin-C, neutrophil gelatinase-associated lipocalin, kidney injury molecule 1, and interleukin-18. Sarcopenia was evaluated using skeletal muscle index on abdominal computed tomography. Frailty was measured using Liver Frailty Index. The research database will be updated to include data on patients' disease outcomes and follow-up care.
