英文摘要 | Background: Nucleos(t)ide analogue (NA) therapy reduces the risk of disease progression in chronic hepatitis B virus-infected patients. However, the risk of liver decompensation, hepatic failure, and mortality after discontinuation of NA therapy remains unknown. Methods: Among 51,574 chronic hepatitis B patients who received NAs in the Taiwan National Health Insurance Research Database, we identified 8,631 patients who continued NA therapy (treatment cohort) and 8,631 propensity-score matched patients who stopped NA therapy after their initial 1.5 years treatment (off-therapy cohort) between October 1, 2003 and December 31, 2011. All study subjects were followed up from the index date, that is, the date 1.5 years after the first prescription of NA, until development of liver decompensation and hepatic failure, death or end of 18-month follow-up period. Results: Treatment cohort had significantly lower risks of liver decompensation (1.05%; 95% confidence interval [CI], 0.81%– 1.30% vs 2.13%; 95% CI, 1.82%–2.45%; p < 0.001), hepatic failure (0.35%; 95% CI, 0.21%–0.49% vs 0.63%; 95% CI, 0.46%– 0.80%; p = 0.008) and overall mortality (1.67%; 1.37%–1.98% vs 2.44%; 95% CI, 2.10%–2.77%; p < 0.001) during the 18-month follow-up period. After adjusting for potential confounders, NA continuous therapy was associated with reduced risks of liver decompensation (hazard ratio [HR]: 0.47; 95% CI, 0.36–0.62, p < 0.001), hepatic failure (HR: 0.53; 95% CI, 0.33–0.86, p = 0.01) and overall mortality (HR: 0.67; 95% CI, 0.53–0.84, p = 0.001). The number needed to reduce one less disease progression and mortality was 47. The protective effect of NA continuous therapy was found in nearly all subgroups. Conclusion: NA continuous therapy is associated with reduced risks of liver decompensation, hepatic failure, and overall mortality. |
