B型肝炎e抗原 HBeAg
Hepatitis B e Antigen (HBeAg)

*HBeAg is a protein produced by the Hepatitis B Virus (HBV) during active viral replication. Its presence in the blood indicates a high level of viral activity and transmissibility.

*Normal Range
Negative <1.0 S/CO
Negative: Indicates low or no viral activity; the infection may be in an inactive or resolved phase.
Positive: Indicates high viral replication and infectiousness, often associated with acute or chronic active HBV infection.

*Significance of HBeAg Positivity
-High Infectivity:
HBeAg positivity suggests that the individual has a high HBV viral load, increasing the risk of transmitting the virus to others through blood or bodily fluids.
-Acute or Chronic Infection:
--Acute HBV Infection: HBeAg appears early and persists during the acute phase.
--Chronic HBV Infection: In some chronic cases, HBeAg remains positive, reflecting active viral replication and liver damage risk.
--Progression and Prognosis:
Prolonged HBeAg positivity in chronic infection is associated with higher risks of liver inflammation, fibrosis, cirrhosis, and liver cancer.

*Health Recommendations
-Further Evaluation:
--HBV DNA Viral Load Testing: To assess the degree of viral replication.
--Liver Function Tests (LFTs): To evaluate liver damage.
--HBeAb (Anti-HBe) Testing: To monitor seroconversion, which indicates reduced viral replication.
-Treatment and Monitoring:
--Antiviral Therapy: HBeAg-positive chronic patients with high viral loads and liver damage may benefit from antiviral treatment to suppress replication.
--Regular follow-ups with a healthcare provider to monitor liver health and infection status.
-Infection Control:
--Avoid sharing needles, razors, or personal items.
--Practice safe sex and inform close contacts for proper precautions.
-Vaccination for Close Contacts:
Household members and sexual partners should be vaccinated against HBV if not already immune.

*Conclusion
HBeAg positivity indicates active HBV replication and high transmissibility. Prompt medical evaluation, regular monitoring, and appropriate antiviral treatment are crucial to managing the infection, protecting liver health, and preventing transmission.
