[Basic factors affecting the development of chronic hepatitis B virus infection]

Area of Science:

• Hepatology and Virology
• Infectious Diseases
• Immunology

Context:

• Study followed 276 individuals with persistent Hepatitis B surface antigen (HBsAg) positivity for five years.
• Included patients with chronic persisting hepatitis, chronic active hepatitis, liver cirrhosis, and asymptomatic HBsAg carriers.
• Focused on the subgroup of 128 patients with chronic active hepatitis who were initially positive for Hepatitis B e-antigen (HBeAg).

Purpose:

• To investigate the long-term outcomes of HBsAg carriers after viral hepatitis B.
• To determine the incidence and causes of acute relapses in HBeAg-positive patients over a five-year period.
• To analyze the relationship between HBeAg seroconversion and disease exacerbation.

Summary:

• Over five years, 43 out of 128 HBeAg-positive patients achieved HBeAg seroconversion (negativity), at an annual rate of 6.7%.
• 38 patients experienced acute relapses, attributed to factors including Hepatitis A virus, Hepatitis non-A non-B virus, EB virus, cytomegalovirus, HBeAg to anti-HBe seroconversion (36.8%), and corticotherapy discontinuation (15.8%).
• HBeAg to anti-HBe seroconversion was linked to acute exacerbations in about one-third of cases, typically transient with subsequent improvement. Relapses post-corticotherapy also often resolved spontaneously.

Impact:

• Provides insights into the complex natural history of chronic Hepatitis B infection.
• Highlights the multifactorial nature of disease relapses in HBsAg carriers.
• Suggests that while HBeAg seroconversion can trigger transient exacerbations, it may ultimately contribute to improved outcomes in some chronic hepatitis B patients.
