Carvedilol Versus Other Nonselective Beta Blockers for Variceal Bleeding Prophylaxis and Death: A Network Meta-analysis.

ABSTRACT:

Background and aims

We aimed to perform a network meta-analysis (NWM) to examine comparative effectiveness of non-selective beta blockers (NSBBs) on prophylaxis of gastroesophageal variceal bleeding (GVB) and mortality benefit.

Methods

MEDLINE (OVID) and EMBASE databases were searched for eligible randomized clinical trials (RCTs) from inception to July 3, 2021. Outcomes of interest included primary/secondary prophylaxis of GVB, failure to achieve hepatic venous pressure gradient (HVPG) decremental response, liver-related and all-cause mortality. A Bayesian NWM was performed to derive relative risk (RR) with 95% credible intervals (CrIs). The ranking probability of each NSBB was assessed by surface under cumulative ranking curve (SUCRA).

Results

Thirty-three RCTs including 3,188 cirrhosis patients with gastroesophageal varices were included. Compared with placebo, nadolol ranked first for reducing variceal bleeding [RR:0.25, (95% CrI:0.11-0.51); SUCRA:0.898], followed by carvedilol [RR:0.33, (95% CrI: 0.11-0.88); SUCRA:0.692] and propranolol [RR:0.52, (95% CrI:0.37-0.75); SUCRA:0.405]. Carvedilol was more effective than propranolol in achieving HVPG decremental response [RR:0.43, (95% CrI: 0.26-0.69)]. Carvedilol ranked first for reducing all-cause mortality [RR: 0.32, (95% CrI:0.17-0.57); SUCRA:0.963), followed by nadolol [RR:0.48, (95% CI:0.29-0.77); SUCRA:0.688], and propranolol [RR:0.77, (95% CI:0.58-1.02); SUCRA: 0.337]. Similar findings were observed for liver-related mortality. Carvedilol ranked the safest. The RR of adverse events was 4.38, (95% CrI:0.33-161.4); SUCRA:0.530, followed by propranolol [RR: 7.54, (95% CrI:1.90-47.89); SUCRA:0.360], and nadolol [RR: 18.24, (95% CrI:91.51-390.90); SUCRA:0.158].

Conclusions

Carvedilol is the preferred NSBB with better survival benefit and lower occurrence of adverse events among patients with gastroesophageal varices.

Project description:Background and aimsNoninvasive tools (NITs) reliably categorise patients with compensated advanced chronic liver disease (cACLD) into high-risk and low-risk group for harbouring varices needing treatment. Here, we assess the ability of these NITs to predict the need for nonselective beta-blockers at baseline based on risk of variceal bleeding (VB) on follow-up.MethodsThis was a retrospective multicentre analysis of patients with cACLD categorised at baseline into different risk groups by NITs (Baveno-VI, expanded Baveno-VI, platelet-albumin, platelet-model for end-stage liver disease (MELD) and anticipate study platelet criteria) and by endoscopy (high risk vs low risk/no varices). VB event rates on follow-up were estimated in different risk strata. Decision curve analysis (DCA) was used to estimate the benefit of administering nonselective beta-blockers (NSBB) using NITs over endoscopic classification at different threshold probabilities of VB event rates and estimating the number needed to treat (NNT) to identify one additional bleeder over endoscopy.ResultsA total of 1284 patients (mean age: 44.7 ± 13.5 years, 72.4% males) of hepatitis B (29.2%), nonalcoholic fatty liver disease (24.9%), hepatitis C (20.1%), and alcohol (17.5%)-related cACLD were included with 323 (25.2%) having high-risk varices. Ninety-eight (7.6%) patients developed VB over a median follow-up of 20 (9-35) months. The 1-year and 3-year rate of VB with all NITs was 5.7-7.4% and 13.2-16.4% among high-risk and 0-2.3% and 0-5% among low-risk subgroups, respectively (P < 0.001) in both viral and nonviral aetiologies. Among patients classified as low risk on Baveno-VI criteria, none developed VB on follow-up. At thresholds of <3% event rate of VB, Baveno-VI (NNT-176), platelet-albumin (NNT-576) and anticipate platelet (NNT-233) criteria were superior, whereas endoscopic stratification was superior above this event rate on DCA.ConclusionsThe use of both elastography and blood-based NITs at baseline can accurately identify the need for NSBB for VB prophylaxis in patients of cACLD on follow-up.

Project description:BackgroundVarious non-invasive markers predicting hepatic fibrosis are poor predictors of esophageal variceal bleeding (EVB). Elastography performs well but resource-limited. Controversy for small EV prevention also exists. We aim to investigate if a non-invasive marker could predict subsequent EVB within 1 and 2 years in patients with compensated liver cirrhosis (CLC), initial small EV without red-color sign (RCS), without use of non-selective beta-blockers (NSBB) and endoscopic variceal ligation (EVL). This marker would also be tested if it could help reduce use of NSBB, thereby avoiding potential side effects and saving medical costs.MethodsIn this retrospective cohort study, 6,803 CLC patients fulfilling the inclusion-exclusion criteria were enrolled between 2001 and 2018, and were followed-up for 1 year, 2 years. The primary outcomes were subsequent EVB within 1 and 2 years of enrollment. Another 281 CLC patients with NSBB use were compared for additional outcome analysis.ResultsIn total, 539 patients and 710 patients experienced EVB within 1 year and 2 years, respectively. The fibrosis index (FI) with cut-off value of 3.95 showed a negative predictive value (NPV) of 94.3% and an area under receiver operating characteristic (AUROC) of 62.95% for predicting subsequent EVB within 1 year. The EVB and mortality of patients with FI <3.95 and not taking NSBB were significantly lower than those of the other 3 groups. Similar results were demonstrated within 2 years.ConclusionsIn CLC patients with initial small EV and no RCS, low FI scores showed a high NPV and moderate AUROC in predicting subsequent EVB and mortalities, signifying clinically non-significant portal hypertension. Patients with low FI scores and not taking NSBB had significantly lowest EVB and mortality. The medical cost savings for cutting NSBB in these patients would be estimated at least $3 million per year in the U.S. Further randomized control trial study needed to validate this screening tool.
