Lamivudine for chronic hepatitis B: a brief review
1Pediatrics Department, Sondrio Hospital, Italy. emipalu2003@yahoo.it
Summary
Lamivudine offers a new treatment option for chronic hepatitis B, showing improved efficacy over alpha-interferon for many patients. This review details its properties and effectiveness in treating specific hepatitis B virus (HBV) infections.
Area of Science:
- Hepatology
- Virology
- Pharmacology
Background:
- Alpha-interferon was the primary treatment for chronic hepatitis B, but offered limited sustained response rates (20-40%).
- Lower efficacy was observed in patients with precore-mutant hepatitis B virus (HBV) strains.
- Lamivudine gained FDA approval in 1998 as a treatment for chronic hepatitis B.
Purpose of the Study:
- To review the pharmacokinetic and pharmacodynamic properties of lamivudine.
- To evaluate the efficacy and tolerability of lamivudine in treating chronic hepatitis B.
- To focus on patients positive for both HBeAg and anti-HBe.
Main Methods:
- Literature review of studies on lamivudine for chronic hepatitis B.
- Analysis of pharmacokinetic and pharmacodynamic data.
- Assessment of clinical trial results regarding efficacy and tolerability.
Main Results:
- Lamivudine demonstrated significant antiviral activity and clinical improvement in chronic hepatitis B patients.
- Pharmacokinetic data indicated favorable absorption, distribution, metabolism, and excretion profiles.
- Tolerability was generally good, with manageable side effects.
Conclusions:
- Lamivudine represents an important therapeutic advance for chronic hepatitis B.
- It offers a more effective treatment option compared to previous therapies, particularly for specific patient groups.
- Further research may explore long-term outcomes and resistance patterns.

01:28Viral 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...
01:25Hepatitis
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...
01:22Antiviral 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),...
01:10Retrovirus Life Cycles
Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the retrovirus to...
01:30Inhibitors 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...
01:26Diseases of the Liver and Gallbladder
Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not related to...
