ABSTRACT

Objective To investigate the correlation between the anti-nuclear antibody(ANA)pattern and the specific ANA spectrum.Methods 974 cases of detected ANA results in our hospital were analyzed retrospectively.The ANA pattern was detec-ted by the indirect immunofluorescence(IIF)and the specific ANA spectrum was tested by the line immunoassay(LIA).199 cases of both simultaneous positive results by IIF and LIA were analyzed and the correlation between ANA patterns and specific ANA spectrum was analyzed.Results Among 974 cases of specimen,249 cases(25.6%)were positive by IIF and 237 cases(24.3%) were positive by LIA,the difference in the positive rate between IIF and LIA had no statistical significance(P >0.05 ).287 cases (29.5%)were positive by single IIF or LIA or both IIF and LIA,which was higher than the positive rate by single IIF or LIA (P <0.05).Among 249 cases of positive by IIF,119 cases(79.9%)were positive by LIA,among 725 cases of negative by IIF,687 (94.8%)cases were negative by LIA.The anti-Ro-52 antibody was frequently detected in the nuclear speckled pattern,and the an-ti-M2 antibody was detected more frequently in the cytoplasmic speckled pattern,anti-dsDNA antibody and anti-nucleosome anti-body were more frequently detected in the nuclear homogeneous pattern,anti-centromere antibody was more frequently detected in the centromere pattern and anti-PM-Scl antibody was more frequently detected in the nucleolus pattern.Conclusion The ANA de-tection has better correlation between IIF and LIA,but also has certain difference.Their combined detection can reduce the missed detection rate and has the important significance to the diagnosis,disease condition monitoring and prognosis judgment of autoim-mune diseases.
