ABSTRACT
Objective To establish the enzyme-linked immunosorbent assay (ELISA)method in detecting the anti-M3RP antibody in Sj(o)gren's syndrome (SS) patients.and to explore the significance of this autoantibody in the diagnosis of SS.Methods The synthesized M3 receptor polypeptide was used as antigen in EUSA to detect the anti-M3RP antibody in sera of patients with SS.other CTDS and healthy controls.and the association between the clinical features of SS and anti-M3RP antibody was analyzed.Results Antibodies against M3RP were detected in 84.6%patients with pSS and 81-3% with sSS.8.8%with other CTD and 1%in heahhy controls.The positive rates of antibodies in pSS and sSS were higher than those in other CTDs and healthy controls.The presence of anti-M3RP antibodies had no significant correlation with clinical manifesta-tions and internal organ involvement.Furthermore.the positive rates of anti-M3RP antibodies in anti-α-fodrin.SSA,SSB,and ANA antibodies negative SS patients were 85%.89-3%,88.9%and 95.2%,respectively.body is a complementary parameter in the diagnosis of antibody-negative SS.
