The correlation of antibodies to nuclear ribonucleoprotein (RNP) and nuclear acidic protein (Sm) with nephritis in patients with systemic lupus erythematosus (SLE).

The role of antibodies to Sm and RNP in renal diseases in SLE was investigated using counter immunoelectrophoresis (CIE). Antibody to RNP was found in about 50% of lupus patients irrespective of the degree of renal involvement as evaluated clinically, histologically and immunopathologically. Antibody to Sm was found more frequently in lupus patients with renal lesions than in those without renal disease. Antibody to RNP was demonstrated in 8 of 10 (80%) and antibody to Sm in 4 of 10 (40%) specimens obtained by elution of autopsied kidneys. These results suggest that antibodies to RNP and Sm are also of importance in the pathogenesis of lupus nephritis in addition to the already recognized role of antibody to ds-DNA.

Profiles of antinuclear antibodies in systemic rheumatic diseases.

The prevalence of different antinuclear antibodies was examined in systemic lupus erythematosus, rheumatoid arthritis, Sjögren's syndrome, progressive systemic sclerosis, dermatomyositis, discoid lupus erythematosus, and mixed connective tissue disease. Antibody to Sm antigen (a nuclear acidic protein) was found almost exclusively in serums of patients with systemic lupus erythematosus, suggesting that this antibody might be a "marker" antibody for this disease. However, antibodies to native DNA and to nuclear ribonucleoprotein were found in a variety of systemic rheumatic diseases. In systemic lupus erythematosus, antibody to native DNA was present in high titer but in other rheumatic diseases in low titer. Antibody to nuclear ribonucleoprotein occurred in certain other systemic rheumatic diseases besides the mixed connective tissue disease syndrome. These studies showed that there were distinct profiles of antinuclear antibodies in certain systemic rheumatic diseases, characterized by the presence or absence of certain antibodies and by differences in their mean titers.
