Summary
Hepatitis B virus (HBV) infection in pregnant women typically shows a mild clinical course, but flares are common post-delivery. Antiviral therapy in late pregnancy can reduce vertical transmission risks in high-risk cases.
Area of Science:
- Hepatology
- Infectious Diseases
- Maternal-Fetal Medicine
Background:
- Hepatitis B virus (HBV) infection during pregnancy often presents a similar clinical course to non-pregnant individuals.
- Hepatitis flares are infrequent during pregnancy but common postpartum. HBV carrier status correlates with increased risks of gestational diabetes, preterm labor, and miscarriage.
Purpose of the Study:
- To review the management of HBV infection in pregnant women.
- To discuss the risks and benefits of antiviral therapy during pregnancy.
- To highlight strategies for preventing neonatal HBV transmission.
Main Methods:
- Literature review of HBV management in pregnancy.
- Analysis of clinical outcomes and transmission risks.
- Evaluation of immunoprophylaxis and antiviral therapy efficacy.
Main Results:
- Hepatitis flares are rare during pregnancy but frequent postpartum.
- HBV carrier status is linked to adverse pregnancy outcomes like gestational diabetes and preterm labor.
- Neonatal immunoprophylaxis is highly effective but residual transmission risk exists with high maternal HBV DNA levels.
Conclusions:
- Antiviral therapy in the third trimester can mitigate residual neonatal HBV transmission risk in high-viremic pregnant women.
- Treatment decisions for pregnant women with HBV require balancing antiviral risks against hepatitis flare progression.
- Effective neonatal immunoprophylaxis significantly reduces vertical HBV transmission.

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...
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...
Genital Herpes
Genital herpes is a sexually transmitted infection primarily caused by herpes simplex virus type 2 (HSV-2), though herpes simplex virus type 1 (HSV-1) is increasingly implicated in genital infections, particularly among younger populations. Transmission occurs mainly through sexual contact, with asymptomatic viral shedding serving as a major route of spread. This characteristic makes HSV-2 difficult to control at a population level, as individuals may unknowingly transmit the virus even in the...
Rh Blood Group
The Rhesus (Rh) antigen is crucial in determining blood groups and ensuring compatibility during blood transfusions.
Sexually Transmitted Infections
Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...
