[Antinuclear, anticentromere and anti-ScL-70 antibodies in rheumatic diseases].
Methods are described that are used for the titration of antinuclear, anticentromere, and anti-Scl-70 antibodies in systemic scleroderma, systemic lupus erythematosus, and rheumatoid arthritis: indirect immunofluorescence with various antigenic substrates (sections of fresh-frozen rat liver and Hep-2 cell culture), counter-current immunoelectrophoresis, isolation of Scl-70 antigen. Use of Hep-2 cells as a substrate for indirect immunofluorescence was found clinically and diagnostically more effective since it permitted the detection of anticentromere antibodies and anti-Scl-70. Nucleolar, mottled, homogeneous, marginal immunofluorescence types were observed when rat liver sections and Hep-2 cells were used for substrates. Anticentromere antibodies and anti-Scl-70 were isolated significantly more frequently in systemic lupus erythematosus or rheumatoid arthritis.
