Insights
Entecavir is a safe and effective antiviral treatment for chronic hepatitis B (CHB) virus carriers, showing significant virological and biochemical responses without serious side effects or disease progression.
Area of Science:
- Hepatology
- Virology
- Pharmacology
Background:
- Chronic hepatitis B (CHB) infection affects millions globally.
- Antiviral therapy is crucial for managing CHB and preventing complications.
- Entecavir is a nucleoside analog used in CHB treatment.
Purpose of the Study:
- To assess the short-term efficacy and safety of entecavir in CHB virus carriers.
- To compare treatment outcomes between CHB virus carriers and CHB patients.
Main Methods:
- Ninety-three CHB patients (carriers and non-carriers) received 0.5 mg entecavir daily for 48 weeks.
- Virological, serological, and biochemical markers were monitored throughout the study.
- Adverse events, liver cirrhosis, and hepatocellular carcinoma incidence were recorded.
Main Results:
- Both groups showed high rates of complete and partial virological response, with no significant differences observed.
- Serological response and HBeAg seroconversion rates were comparable between groups.
- No virologic or biochemical breakthrough, liver cirrhosis, or hepatocellular carcinoma occurred; entecavir was well-tolerated.
Conclusions:
- Entecavir demonstrates significant efficacy and safety in treating CHB virus carriers.
- The drug is well-tolerated, with no observed serious adverse events or disease progression during the study period.
Objective:
To evaluate the short-term effect and safety of entecavir for the treatment of chronic hepatitis B (CHB) virus carriers.
Methods:
Ninety-three cases of CHB virus infection (hepatitis B surface antigen (HBsAg)-positive, hepatitis B e antigen (HBeAg)-positive, hepatitis B core antibody (HBcAb)-positive, HBV DNA≥1x10(5) copies/mL) were divided into two groups: CHB virus carrier (47 cases) and CHB (46 cases). All of the 93 cases were given 0.5 mg entecavir orally once a day for 48 weeks. Virology, serology and biochemistry tests were perrmed at treatment weeks 0, 4, 12, 24 and 48. Side effects of entecavir and the incidence of liver cirrhosis and hepatocellular carcinoma were recorded.
Results:
The CHB virus carrier and CHB group had complete virological response rates of 14.9% and 17.4% at week 4, 51.1% and 63.0% at week 12, 76.6% and 89.1% at week 24, and 97.9% and 100% at week 48, respectively; there was no significant difference between the two groups (P>0.05). The CHB virus carrier and CHB group had partial virological response rates of 42.6% and 47.8% at week 4, 57.44% and 65.2% at week 12, 85.0% and 89.1% at week 24, and 100% and 100% at week 48, respectively; there was no significant difference between the two groups (P>0.05). No cases in either group experienced virologic breakthrough during the treatment course. The CHB virus carrier and CHB group had serological response (HBeAg-negative) rates of 0 and 4.3% at week 4, 2.1% and 8.7% at week 12, 4.3% and 13.0% at week 24, and 8.5% and 21.7% at week 48, respectively; there was no significant difference between the two groups (P>0.05). The CHB virus carrier and CHB group had HBeAg seroconversion rates of 0 and 0 at week 4, 0 and 4.4% at week 12, 2.1% and 10.9% at week 24, and 6.4% and 17.4% at week 48, respectively; there was no significant difference between the two groups (P>0.05). No case in either group showed HBsAg-negativity and seroconversion during the treatment course. The CHB group had a biochemical response (alanine aminotransferase normalization) rate of 26.1% at week 4, 65.2% at week 12, 91.3% at week 24, and 97.8% at week 48.No case in either group showed biochemical breakthrough during the treatment course. There were no cases of liver cirrhosis or hepatocellular carcinoma in either group. There were no side effects of the entecavir treatment experienced in either group.
Conclusion:
Antiviral therapy with entecavir is effective, safe and well tolerated in CHB virus carriers.
