Аннотация:Hepatitis B virus (HVB) infection is a worldwide epidemic that, in addition to the liver, causes damage in other organs. HBV-membranous nephropathy (HBV-MN) is the most common renal manifestation in patients with HBV infection,1–3 possibly linked to subepithelial deposits of viral immune complexes.4,5 HBV RNA and DNA were detected in glomerular and tubular cells, although a pathogenetic role for these viral nucleic acids remains to be confirmed.6 The effects of vaccination programs on the decline of HBV-associated MN, particularly in Asian and African children,7,8 further support a possible relationship between HBV infection and MN.
