Insights

Chronic hepatitis B infection can progress to severe liver disease, including cirrhosis and liver cancer. HBeAg-negative hepatitis B, a late-stage infection, is increasing and associated with poorer outcomes.

Area of Science:

  • Hepatology
  • Virology
  • Gastroenterology

Background:

  • Chronic hepatitis B virus (HBV) infection presents diverse clinical courses.
  • Infection can range from inactive carrier state to progressive hepatitis, cirrhosis, and hepatocellular carcinoma (HCC).
  • HBeAg-positive and HBeAg-negative hepatitis B represent distinct phases with differing prognoses.

Purpose of the Study:

  • To describe the natural history and clinical significance of chronic hepatitis B.
  • To highlight the increasing prevalence and severity of HBeAg-negative chronic hepatitis B.
  • To outline the progression, morbidity, and mortality associated with chronic HBV infection.

Main Methods:

  • Review of longitudinal studies on chronic hepatitis B patients.
  • Analysis of disease progression, including development of cirrhosis and hepatic decompensation.
  • Examination of survival rates based on disease severity and cirrhosis status.

Main Results:

  • HBeAg-negative chronic hepatitis B, caused by HBV variants, is increasing globally and represents the majority of cases in many regions.
  • This late-phase infection is linked to more severe liver disease, low spontaneous remission rates, and poor response to antiviral therapy.
  • The 5-year cumulative incidence of cirrhosis is 8-20%, hepatic decompensation is ~20%, and survival varies significantly with cirrhosis severity.

Conclusions:

  • HBeAg-negative chronic hepatitis B is a significant and growing public health concern with a poorer prognosis.
  • Progression to cirrhosis and HCC are the main drivers of morbidity and mortality in chronic HBV infection.
  • Effective management and monitoring are crucial to improve outcomes for patients with chronic hepatitis B, particularly the HBeAg-negative form.

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...
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...
Cirrhosis I: Introduction01:23

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...
Yellow Fever01:18

Yellow Fever

Yellow fever is a viral hemorrhagic disease caused by the yellow fever virus (YFV), a member of the Flaviviridae family. It is transmitted primarily by Aedes and Haemagogus mosquitoes in tropical and subtropical regions of Africa and South America. After transmission through a mosquito bite, the virus initially replicates in skin-resident immune cells such as dendritic cells and macrophages. These cells then migrate to the lymph nodes, where viral replication increases, eventually leading to...
Viruses with RNA Genomes01:29

Viruses with RNA Genomes

RNA viruses are categorized into positive-strand, negative-strand, or double-stranded groups based on their genomic structure and replication mechanisms. This classification dictates how they exploit host cellular machinery for protein synthesis and replication. Some RNA viruses also utilize reverse transcription as part of their life cycle, further diversifying their replication strategies.Positive-Strand RNA VirusesPositive-strand RNA viruses have genomes that function directly as messenger...
Retroviruses02:33

Retroviruses

Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...
