Abstract
Background
The efficacy of nucleos(t)ide analogs (NAs) in non-cirrhotic chronic hepatitis B (CHB) patients is well-established. However, their impact on complications of portal hypertension in advanced chronic liver disease (ACLD) is less well characterized.
Methods
MEDLINE/PubMed, EMBASE, Web of Science, Cochrane Central Register of Controlled Trials, and abstracts of major international hepatology meetings were searched for publications from Jan 1, 1995 to Nov 30, 2021. Randomized control trials and observational studies reporting the efficacy of NAs in ACLD patients were eligible. Pooled risk ratios (RRs) for outcomes of interest were calculated with a random-effect or fixed-effect model, as appropriate.
Results
Thirty-nine studies including 14,212 ACLD patients were included. NA treatment was associated with reduced risks of overall hepatic decompensation events (RR, 0.51; 95% confidence interval [CI]: 0.37–0.71), such as variceal bleeding (RR, 0.44; 95% CI: 0.26–0.74) and ascites (RR, 0.10; 95% CI: 0.01–1.59), on a trend-wise level. Moreover, the risks of hepatocellular carcinoma (HCC) (RR, 0.48; 95% CI: 0.30–0.75) and liver transplantation/death (RR, 0.36; 95% CI: 0.25–0.53) were also reduced by NA treatment and the first-line NAs were superior to non-first-line NAs in improving these outcomes (RR, 0.85; 95% CI: 0.75–0.97 and RR, 0.85; 95% CI: 0.73–0.99, respectively).
Conclusion
NA therapy lowers the risk of portal hypertension-related complications, including variceal bleeding, HCC, and liver transplantation/death. |
