Autoimmune hepatitis with membranous glomerulonephritis.
We report on a case of autoimmune hepatitis (AIH) associated with membranous glomerulonephritis. A 61-year-old woman was admitted because of peripheral edema, proteinuria and abnormal liver function test findings. A diagnosis of AIH was made on the basis of an elevation of aminotransferase and serum IgG levels, the presence of positive antinuclear antibody and the characteristic histological features of chronic active hepatitis. Histological examination of a renal biopsy specimen disclosed membranous glomerulonephritis with granular deposits of IgG, IgM, C3 and C1q along the capillary walls. This condition is rare in AIH and should be carefully distinguished from systemic lupus erythematosus.
