Insights
Response-guided add-on therapy with adefovir (ADV) and lamivudine (LAM) effectively suppresses hepatitis B virus (HBV) DNA and improves liver function in cirrhotic patients. This optimized treatment strategy reduces viral load and minimizes drug resistance for long-term management of chronic hepatitis B.
Area of Science:
- Hepatology
- Virology
- Pharmacology
Background:
- Chronic hepatitis B (CHB) with cirrhosis presents a significant clinical challenge.
- Lamivudine (LAM) monotherapy is a common initial treatment, but response rates vary.
- Adefovir (ADV) is an alternative nucleotide analog used in HBV treatment.
Purpose of the Study:
- To evaluate the efficacy of response-guided add-on therapy with adefovir (ADV) and lamivudine (LAM) in patients with CHB and cirrhosis.
- To assess the impact of different treatment strategies on viral suppression and YMDD mutations.
- To determine the effect on biochemical markers and liver function.
Main Methods:
- 100 CHB patients with cirrhosis were stratified into three groups based on HBV DNA levels after 24 weeks of LAM monotherapy.
- ADV was added to LAM at different time points (week 24 or 48) based on the initial response.
- Virological response, YMDD mutations, biochemical response, and liver function were monitored over 144 weeks.
Main Results:
- Early complete virologic response at 24 weeks correlated with sustained viral suppression (95.96% undetectable HBV DNA at 144 weeks) and minimal YMDD mutations (0%).
- For incomplete responders, combination therapy reduced HBV DNA by 1 log10 IU/mL.
- All treatment arms showed biochemical improvements, including decreased ALT and increased albumin. ADV add-on did not induce further resistance in patients with YMDD mutations.
Conclusions:
- Optimized response-guided add-on therapy with ADV and LAM provides long-term HBV DNA suppression in CHB patients with compensated cirrhosis.
- This strategy effectively improves liver function and biochemical parameters.
- The approach is valuable for managing CHB patients, minimizing resistance development.
Aim:
To observe the effect of response-guided add-on therapy with adefovir (ADV) and lamivudine (LAM) in cirrhotic hepatitis B (CHB) patients.
Methods:
A total of 100 patients with CHB and cirrhosis were divided into three arms according to hepatitis B virus (HBV) DNA level after 24 wk LAM monotherapy: Arm A (complete response, HBV DNA ≤ 60 IU/mL, n = 49), Arm B (partial response, HBV DNA: 60-2000 IU/mL, n = 31) and Arm C (inadequate response, HBV DNA > 2000 IU/mL, n = 20). ADV was added to LAM at week 48 in Arms A and B, but at week 24 in Arm C. Virological response, YMDD mutations, biochemical response, and liver function were evaluated.
Results:
Comparison of the three arms demonstrated that early complete virologic response at week 24 was associated with maintained viral suppression (undetectable rate of HBV DNA at week 144 was 95.96%, 66.67% and 35.29%, respectively, P = 0.000) and reduced YMDD mutations (mutation rate at week 144 was 0%, 3.23% and 15%, respectively, P = 0.015) after 144 wk treatment. For patients who failed to achieve complete virological response at week 24, switching to combination therapy further decreased HBV DNA level by 1 log10 IU/mL. All three arms obtained biochemical benefits including decline of alanine aminotransferase and elevation of albumin. In patients who developed HBV DNA breakthrough for YMDD mutations, ADV add-on therapy did not induce further multiple drug resistance to LAM or ADV.
Conclusion:
Optimized response-guided add-on therapy of ADV and LAM maintains long-term suppression of HBV DNA and improves liver function in CHB patients with compensated liver cirrhosis.
