Hepatitis B virus-related glomerulopathy in patients with systemic lupus erythematosus.
The clinical data and renal pathologic information from three patients with systemic lupus erythematosus (SLE), active glomerular disease, and hepatitis B virus (HBV) antigenemia are presented. All three patients fulfilled the American Rheumatism Association criteria for the diagnosis of SLE. However, the renal pathologic results excluded the diagnosis of lupus nephritis. The common findings shared by these patients included the following: presence of hepatitis B surface antigen (HBsAg) in both serum and glomeruli and of glomerular hepatitis B core antigen (HBcAg), and the absence of polyclonal immunoglobulins, C1q and C4, deposition in renal tissue. These common features and the renal pathologic results indicated that the glomerulopathy was associated with HBV antigenemia. The cases described here may represent a subset of patients with SLE in whom expression of lupus nephritis was altered by the concomitant HBV-related glomerulonephritis.
