IgD deposits were investigated by an indirect immunofluorescence technique in 180 renal biopsies carried out on patients with various renal diseases. IgD was not present in nephrotic syndrome with minimal changes or focal glomerulosclerosis, in mesangial proliferative glomerulonephritis, in chronic advanced glomerulonephritis, in rheumatoid purpura and in other various nephropathies with predominant non glomerular lesions. Significant deposits of IgD were identified in 12 out of 16 cases of membranoproliferative glomerulonephritis, in 15 out of 23 cases of membranous nephropathy, in 11 out of 21 cases of focal proliferative glomerulonephritis with mesangial IgA deposits, in 2 out of 5 cases of proliferative glomerulonephritis with crescents and in 1 out of 6 cases of proliferative exudative glomerulonephritis. All cases of lupus nephritis and nephritis associated with mixed cryoglobulinemia showed IgD deposits. In diabetic glomerulosclerosis, IgD was found in 1 out of 4 biopsies and only in the exudative lesions. In 5 out of 8 cases of amyloidosis anti IgD serum stained the amyloid substance irregularly. In such cases IgD was found in association with other immunoglobulins and complement with the same localization. These findings suggest that IgD may participate in the immunological processes which lead to the development of glomerular deposits, mainly in cases of chronic glomerular diseases.
