Treponemal antigens in congenital and acquired syphilitic nephritis: demonstration by immunofluorescence studies.
Two patients, a 4-month-old infant girl with congenital syphilis and a 45-year-old man with secondary syphilis, had the nephrotic syndrome with glomerulonephritis. Immunoglobulins and treponemal antigenic material were seen in the glomeruli of both patients by immunofluorescence microscopic studies of renal tissue. Electron micrographs showed subepithelial electron dense deposits along the glomerular basement membrane. This confirms earlier suggestions that the renal injury is of an immune-complex type.
