  • Analysis of the Relationship between Fluorescence Patterns of Antinuclear Antibody and Antinuclear Antibody Profiles

    ObjectiveTo discuss the relationship between antinuclear antibody (ANA) fluorescence pattern detected by indirect immunity fluorescence (IIF) and antinuclear antibody profiles (including anti-dsDNA, RNP, Sm, SSa, SSb, Scl-70, Jo-1 and rib-P) in human serum. MethodsA total of 7385 cases of ANA pattern and ANA profiles were retrospectively analyzed from January 2010 to December 2013. ANA was detected by IIF substrated as HEp-2 cells, anti-dsDNA by IIF substrated as crithidia, and the other 7 antibodies by enzyme immunoblot with purified antigen. ResultsGranular pattern mostly presented as anti-RNP, anti-Sm, anti-SSa and anti-SSb (P < 0.001); homogeneous pattern was anti-dsDNA and anti-SSa (P < 0.001); nucleolus, centromere, and mixed pattern was anti-SSa (P < 0.05); cytoplasm pattern was anti-rib-P and anti-SSa (P < 0.05). But few above antibodies could be detected in Golgi, dots, rim, actin, actotropomyosin, prolifevating cell nuclear antigen (PCNA) and vementin pattern. Homogeneous pattern was shown up to 77.91% in only anti-dsDNA positive serum; granular was 96.84%, 52.01%, and 82.35% respectively in only anti-RNP or anti-SSa or anti-Sm positive. Homogeneous and nucleolus mix pattern was up to 30.53% in only anti-Scl-70 positive. Cytoplasm pattern was 50.00% and 61.54% respectively in only anti-rib-P or anti-Jo-1 positive. But no fixed relationship was found between ANA pattern and anti-SSb. ConclusionsThere is a certain relationship between ANA and antinuclear antibody profiles. Granular, homogeneous and cytoplasm pattern often can be detected more than one autoantibodies. Eight kinds of specific autoantibodies often are negative when ANA patterns are centromere, Golgi, dots, rim, actin, tropomyosin, PCNA, and vimentin. Anti-dsDNA is mainly corresponding to homogeneous, anti-RNP, anti-SSa and anti-Sm to granular, anti-Scl-70 to homogeneous and nucleoli, anti-rib-P and anti-Jo-1 to cytoplasm. The study can give suggestions for further tests application and lab result checking.
