Abstract
BACKGROUND:
Lamivudine has been widely used in chronic hepatitis B patients with hepatic decompensation, but its use is limited by drug resistance. This outcome research aimed to investigate the comparative efficacy and safety of entecavir versus lamivudine in decompensated patients.
METHODS:
Between November 2004 and February 2010, 126 consecutive treatment-naive patients received either entecavir (n=53) or lamivudine (n=73) for decompensated chronic hepatitis B. All patients presented with both hyperbilirubinaemia and coagulopathy. Primary outcome was mortality within 1 year;
d l d d l l d l b h l d l l d secondary outcomes included liver-related mortality, biochemical and virological response, and improvement of hepatic dysfunction.
RESULTS:
Both treatment groups were comparable in baseline characteristics. A total of 19 (35.8%) entecavir and g p p 33 (45.2%) lamivudine receivers expired within 1 year, respectively (P=0.29, log rank test). Age (hazard ratio [HR] 1.04 per year, 95% CI 1.01, 1.06), cirrhosis (HR 2.07, 95% CI 1.02, 4.23), and international normalized ratio for prothrombin time (HR 1.44, 95% CI 1.20, 1.74) were independent baseline
predictors for all-cause mortality. Antiviral therapy was also unrelated to liver-specific death. However, p ti t t ki g t i t d d t tt i i t f li ti (76 5% 52 5% more patients taking entecavir tended to attain aminotransferase normalization (76.5% versus 52.5%; P=0.05) and viral DNA undetectability (100% versus 58.3%; P=0.06). Moreover, entecavir was
associated with significantly greater reduction of the model for end-stage liver disease scores (median 10.0 versus 4.3; P=0.02). Overall, 3 (7.5%) lamivudine but no entecavir users acquired drug resistance in 1 year (P=0.25).
in 1 year (P 0.25).
CONCLUSIONS:
Entecavir as compared with lamivudine is similar in the effect on short-term mortality but is associated with greater clinical improvement among chronic hepatitis survivors who recovered from hepatic
decompensation decompensation.
