Aim Sarcopenia, the loss of skeletal muscle mass, impairs prognosis of patients with liver cirrhosis. The aim of this study was to investigate the effect of loop diuretics, which are frequently used to treat hepatic edema/ascites, on skeletal muscle depletion and the prognosis in patients with liver cirrhosis. Methods This retrospective study evaluated 226 patients with liver cirrhosis. The skeletal muscle cross‐sectional area at the level of the third lumbar vertebra was measured using computed tomography. The relative change in skeletal muscle area per year (ΔSMA) was calculated, and the association between ΔSMA and therapeutic dosage of loop diuretics was examined. Results The therapeutic dosage of loop diuretics was inversely correlated with ΔSMA by simple (r = −0.27, P < 0.0001) and multiple regression analyses (t = −3.07, P = 0.002). During a median follow‐up period of 49 months, 82 patients died. Overall survival rates were lower in patients treated with loop diuretics at >20 mg than in those who received ≤20 mg (median, 66 vs . 97 months; P = 0.002). Multivariate analysis revealed that loop diuretics of >20 mg (hazard ratio [HR], 1.86; 95% confidence interval [CI], 1.03–3.24; P = 0.039) and ΔSMA of ≤−3.1% (HR, 3.87; 95% CI, 2.32–6.60; P < 0.0001) were independently associated with mortality. Conclusions A higher dose of loop diuretic use was associated with more rapid skeletal muscle depletion and poor survival in patients with liver cirrhosis, independent of the severity of liver disease.
