OBJECTIVE: To distinguish the difference among the pathogenesis of 60 000 SSA antigen mono-antigen peptides (MAPs), and to discuss the nosogenesis of anti-60 000 SSA antibodies in correlative rheumatic diseases. METHODS: MAPs were artificially synthesized according to the amino acid sequence of 20 positive epitopes and 1 control segment of 60 000 SSA antigen. ELISA against recombinant 60 000 SSA antigen MAPs were done to detect anti-MAPs antibodies in 59 sera with anti-SSA antibodies, and analyzing the relations of anti-MAPs antibodies and organism injuries. RESULTS: Anti-60 000 SSA antibodies are multiple clone autoantibodies. Different patients have different immune response to MAPs. Anti-MAP(1 approximately 21) antibodies have no relation to skin lesion; anti-MAP(2,14,15,21) antibodies have positive relation to salivary gland lesion; anti-MAP(7,16) antibodies have negative relation to kidney lesion; anti-MAP(6) antibodies have negative relation to heart lesion. CONCLUSIONS: The appearance of some anti-MAPs antibodies implies the lesions of some organs, while the appearance of some other anti-MAPs antibodies have the protection to some organs. We concluded that it is maybe the different anti-MAPs antibodies that result in different clinical manifestations.
