摘要
Objective To study the pathogenesis of hepatitis B virus ( HBV ) on kidney tissues. Methods HBsAg and HBcAg in paraffin-embedded renal biopsy tissues from 27 cases of glomerulonephritis with positive serum HBV markers were observed by using immunohistochemistry. In addition, in situ polymerse chain reaction (IS-PCR) was performed in 5 cases with positive HBsAg and HBcAg in renal tissue of the 27-case glomerulonephritis to reveal the state of renal HBV DNA. Results Twenty cases (20/27,74.07%) were positive with HBAg which were mainly diffusely distributed in epithelial cells of renal tubule. Four cases (4/5,80% ) were positive with HBV DNA whose distribution was the same of that of HBAg. Conclusion Renal lesions due to HBV are not only the results of immunologic response, but also the outcome of direct invasion and duplication of HBV in epithelial cells of renal tubule.
