Non-selective beta-blocker treatment does not impact on kidney function in cirrhotic patients with varices.

Abstract

GOALS AND BACKGROUND:

Non-selective beta-blockers (NSBBs) are used for bleeding prophylaxis in cirrhotic patients with gastroesophageal varices (GEVs). Recent data suggested that NSBB treatment might increase the risk of renal dysfunction in patients with refractory ascites due to an impaired response to acute haemodynamic stress.

STUDY:

Retrospective longitudinal assessment of kidney function in a cohort of cirrhotic patients with GEVs with vs. without NSBB therapy. Serum creatinine (SCre), estimated glomerular filtration rate (eGFR), incidence of acute kidney injury (AKI), new onset of large volume ascites and TIPS-/transplant-free survival were compared.

RESULTS:

Among 176 patients, 93 patients received NSBBs, while 83 did not. Most patients were male (77.8%), had alcoholic aetiology (52.3%) and compensated cirrhosis (51.1% Child-A, MELD: 12.1 ± 3.8). Over a 3-year follow-up, renal function was comparable between patients with and without NSBB treatment. Incidence of AKI was similar in NSBB vs. no-NSBB patients (p = .323). Even in potential risk groups (ascites, MAP <90 mmHg, baseline creatinine > ULN, hyponatraemia, MELD score ≥15 points, Child-Pugh B/C), there was no difference in SCre or eGFR with vs. without NSBBs (p = n.s. at 74/78 and 76/78 of analysed time points). However, multivariate analysis revealed that the presence of ascites (HR: 3.901, 95%CI: 1.352-11.251; p = .012) and pre-existing renal impairment (HR: 4.315, 95%CI: 1.054-17.672; p = .042) were independent risk factors for AKI. Importantly, NSBB use (HR: 0.319, 95%CI: 0.120-0.848; p = .022) was independently associated with improved TIPS-/transplant-free survival.

CONCLUSIONS:

In our cohort of unselected, mostly compensated cirrhotic patients with GEVs, NSBB treatment was neither associated with worsening of kidney function nor with increased incidence of AKI. On the contrary, NSBB treatment improved TIPS-/transplant-free survival.
