Analysis of clinical features and pathology of serum HBsAg positive glomerulonephritis

Area of Science:

• Nephrology
• Hepatology
• Immunology

Background:

• Hepatitis B virus (HBV) infection is a global health concern.
• HBV-associated glomerulonephritis (HBV-GN) is a significant extrahepatic manifestation.
• Distinguishing HBV-GN from other glomerulonephritis types is crucial for effective management.

Purpose of the Study:

• To investigate the clinical and pathological factors associated with HBV-GN.
• To compare patients with HBV-GN and hepatitis B virus-combined nephritis (HBV-CG).
• To elucidate the relationship between HBV infection status and glomerulonephritis occurrence.

Main Methods:

• A cohort of 56 patients with glomerulonephritis and HBV infection was studied.
• Patients were categorized into HBV-GN (HBsAg/HBcAg in renal tissue) and HBV-CG groups.
• Clinical features and pathological characteristics were analyzed and compared between groups.

Main Results:

• The HBV-GN group showed a higher rate of HBeAg positivity compared to the HBV-CG group.
• A greater number of patients in the HBV-GN group had HBsAg, HBeAg, and HBcAb positivity.
• Fewer patients in the HBV-GN group were diagnosed with minimal change disease (MCD) via renal biopsy.

Conclusions:

• HBV infection and high viral proliferation are strongly associated with the development of HBV-GN.
• Specific serological profiles (HBeAg positivity, HBsAg+HBeAg+HBcAb+) are more prevalent in HBV-GN.
• HBV-GN may present differently pathologically, with a lower incidence of MCD compared to HBV-CG.
