Insights

Lamivudine treatment for pediatric chronic hepatitis B virus (HBV) infection shows that high ALT, low HBV DNA, and younger age predict hepatitis B e antigen (HBeAg) clearance. Achieving viral suppression is key to preventing lamivudine resistance.

Area of Science:

  • Hepatology
  • Virology
  • Pediatric Infectious Diseases

Background:

  • Lamivudine is approved for treating pediatric chronic hepatitis B virus (HBV) infection.
  • Limited data exist on HBV clearance kinetics and predictors of treatment response in children.

Purpose of the Study:

  • To investigate factors predicting hepatitis B e antigen (HBeAg) clearance in children treated with lamivudine.
  • To examine the relationship between viral load suppression and lamivudine resistance.

Main Methods:

  • Retrospective study of 16 children with HBV infection treated with lamivudine.
  • Analysis of changes in viral load and factors associated with HBeAg clearance.

Main Results:

  • High pretherapy alanine aminotransferase (ALT) levels, low serum HBV DNA load, and younger age at treatment initiation were independently associated with HBeAg clearance.
  • HBeAg clearance correlated with achieving specific viral suppression levels.
  • Failure to achieve adequate viral suppression was linked to the development of lamivudine resistance.

Conclusions:

  • Specific baseline characteristics (high ALT, low HBV DNA, younger age) predict HBeAg clearance in pediatric lamivudine treatment.
  • Adequate viral suppression is crucial for treatment success and preventing resistance.
  • Further research is needed to refine treatment guidelines for children with chronic HBV infection.

Viral Hepatitis I: Introduction01:28

Viral Hepatitis I: Introduction

Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...

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. The...

Antiviral Nucleoside Inhibitors

Antiviral Nucleoside InhibitorsAntiviral nucleoside inhibitors are structural analogs of natural nucleosides that interfere with viral DNA or RNA synthesis. These compounds selectively target viral polymerases due to their resemblance to host nucleosides, thereby disrupting viral genome replication.Mechanism of Acyclovir ActionAcyclovir is a guanosine analog with a three-carbon acyclic side chain. It selectively targets herpes simplex virus type 1 (HSV-1), herpes simplex virus type 2 (HSV-2),...
Inhibitors of Viral Protein Synthesis01:30

Inhibitors of Viral Protein Synthesis

Protein synthesis is indispensable for viral replication, as viruses lack the cellular machinery required for this process and must hijack the host's translational apparatus. In response, host cells deploy a critical innate immune defense involving interferons, specialized cytokines that play a central role in inhibiting viral propagation.Upon viral detection, infected cells release interferons that bind to receptors on adjacent uninfected cells, activating the JAK-STAT signaling pathway and...
Cytomegalovirus Disease01:27

Cytomegalovirus Disease

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
