The presence of HBsAg, anti-HBc and often HbeAg is characteristic of what phase of hepatitis?

• A. Early acute phase HBV hepatitis
• B. Chronic HBV infection
• C. Resolved HBV infection
• D. Acute HAV infection

Answer: (A)

The presence of HBsAg (Hepatitis B surface antigen), anti-HBc (antibody to hepatitis B core antigen), and often HBeAg (Hepatitis B e antigen) is indeed indicative of the early acute phase of Hepatitis B virus (HBV) infection. During this phase, HBsAg is detectable as the virus replicates in the liver, marking the active infection. The appearance of anti-HBc suggests that the body is beginning to mount an immune response against the virus. HBeAg, indicating higher viral replication, may also be present, particularly in cases with a high viral load. In the context of chronic HBV infection, while HBsAg would still be present, you would expect anti-HBc to be predominantly IgG rather than IgM, and HBeAg would not always be detected since the disease can present in a stable or inactive carrier state. Resolved HBV infection is characterized by the presence of anti-HBs (antibody to hepatitis B surface antigen) and the absence of HBsAg, meaning that in this phase, the person has cleared the virus and developed immunity. Acute HAV (Hepatitis A virus) infection does not relate to the markers of HBV infection, as
