Non‐selective beta‐blockers decrease infection, acute kidney injury episodes, and ameliorate sarcopenic changes in patients with cirrhosis: A propensity‐score matching tertiary‐center cohort study

Background: Cirrhotic complications resulting from portal hypertension can be consider-ably reduced by non‐selective beta‐blockers (NSBBs); however, scarce studies have investigated therapeutic agents for other complications. We aimed to investigate the effects of NSBBs on common cirrhotic complications of infection, acute kidney injury (AKI), chronic renal function declina-tion, and sarcopenic changes. Methods: Medical records of hospitalization for cirrhosis with at least a 4‐year follow‐up were analyzed and selected using propensity‐score matching (PSM). Generalized estimating equation (GEE) was applied to assess the association of NSBBs with infection requiring hospitalization and AKI. Chronic renal function declination was evaluated by slope of regression lines derived from reciprocal of the serum creatinine level. The covariates of CT‐measured skeletal muscle index (SMI) alterations were analyzed by generalized linear mixed model. Results: Among the 4946 reviewed individuals, 166 (83 NSBB group, 83 non‐NSBB group) were eligible. Using GEE, Charlson comorbidity index, Child‐Pugh score and non‐NSBB were risk factors for infection; non‐ NSBB group revealed a robust trend toward AKI, showed no significant difference with chronic renal function declination of NSBB group, and was negatively associated with SMI alteration. Con-clusion: Chronic NSBB use lowered the episodes of infection requiring hospitalization and AKIs, whereas non‐NSBB was associated with sarcopenic changes.
