Hepatitis B immunisation for newborn infants of hepatitis B surface antigen-positive mothers

Insights

Hepatitis B vaccine and immunoglobulin effectively prevent hepatitis B infection in newborns born to HBsAg-positive mothers. These interventions demonstrate significant benefits with a good safety profile, reducing infection rates substantially.

Area of Science:

  • Immunology
  • Vaccinology
  • Neonatal Medicine

Background:

  • Neonatal transmission of Hepatitis B virus (HBV) from HBsAg-positive mothers poses a significant health risk.
  • Hepatitis B vaccine and hepatitis B immunoglobulin are established interventions to prevent perinatal HBV infection.

Purpose of the Study:

  • To evaluate the efficacy and safety of hepatitis B vaccines and hepatitis B immunoglobulin in preventing HBV infection in infants born to HBsAg-positive mothers.
  • To compare different vaccine types (plasma-derived vs. recombinant) and immunoglobulin combinations.

Main Methods:

  • Systematic review and meta-analysis of 29 randomized clinical trials.
  • Primary outcome: Hepatitis B occurrence confirmed by blood specimen.
  • Subgroup analyses based on trial quality, maternal HBeAg status, and timing of immunisation.

Main Results:

  • Hepatitis B vaccine significantly reduced HBV occurrence compared to placebo/no intervention (RR 0.28, 95% CI 0.20-0.40).
  • Hepatitis B immunoglobulin and combined vaccine plus immunoglobulin also demonstrated significant protective effects.
  • No significant differences were found between recombinant and plasma-derived vaccines, or varying vaccine doses.

Conclusions:

  • Hepatitis B vaccine, hepatitis B immunoglobulin, and their combination are effective in preventing hepatitis B infection in newborns of HBsAg-positive mothers.
  • The interventions appear safe, although comprehensive adverse event data were limited in the reviewed trials.

Development of Immunocompetence01:22

Development of Immunocompetence

The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...

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: 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...
Transcytosis of IgG01:15

Transcytosis of IgG

Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...

Transmission-based Precautions II: Airborne and Protective Environment

Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

Development of the Oral Microbiota

The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
