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.

Hepatitis

Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver.

Cirrhosis I: Introduction

Cirrhosis is a chronic, irreversible liver disease characterized by the widespread replacement of healthy liver tissue with fibrotic scar tissue and the formation of regenerative nodules.Etiology of cirrhosisCirrhosis results from sustained liver injury that triggers progressive fibrosis and structural remodeling. The underlying causes are diverse, encompassing common and less frequent clinical conditions. Regardless of the origin, all causes lead to chronic inflammation, hepatocyte loss, and...

Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test

In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess...
