Abstract:
Objective To understand the fluorescence pattern of antinuclear antibody(ANA)and the distribution of target anti-gen and ANA′s impact on rheumatoid arthritis(RA)RA.Methods The data of rheumatoid factor(RF)and anti-cyclic citrullinated peptide antibodies(anti-CCP antibodies)and ANA of 860 RA patients during 2014-2015 were collected and divided into 2 groups according to the ANA levels.The differences of RF and anti-CCP antibodies level between 2 groups were analyzed.Analyzed the fluorescence pattern of RA merger ANA and the distribution of target antigen by statistical.Results Of the 860 RA patients,the positive rate of ANA was 37.6%,the major fluorescence pattern of RA merger ANA was speckled pattern,anti SSA positive rate was 21.7%.The RF and anti-CCP antibodies level had statistical difference between ANA positive group and ANA negative group (P <0.05).Conclusion RA merger ANA positive can show different fluorescence patterns and target antigen,the speckled pattern and anti-SSA positive are the main pattern.The severity of arthritis symptoms and the degree of bone destruction between ANA positive group and ANA negative group were difference.Anti-ANA positive has a certain promoting effect on the progression of RA disease.
