Abstract:

Objective To investigate the clinical significance of anti-Ro52 and anti-Ro60 antibodies in connective tissue disease (CTD), and to analyze their potential in risk prediction of CTD-associated interstitial lung disease (CTD-ILD). Methods A total of 785 patients diagnosed as CTD and hospitalized in the Department of Rheumatology and Immunology, the Second Hospital of Hebei Medical University from October 2019 to January 2021 were enrolled in this study. Their clinical and laboratory data were collected. According to the testing result for anti-Ro52 and anti-Ro60 antibodies, patients were assigned into anti-Ro52+anti-Ro60- group (n=94), anti-Ro52-anti-Ro60+ group (n=80), anti-Ro52+anti-Ro60+ group (n=251) and anti-Ro52-anti-Ro60- group (n=360). According to the presence or absence of ILD, patients were assigned into CTD with ILD group (n=243) and CTD without ILD group (n=542). Clinical data were compared between groups. Multivariable logistic step-wise regression was performed to assess the potential of anti-Ro52 and anti-Ro60 antibodies in predicting the risk of CTD, especially CTD-ILD. Results Titers of anti-Ro52 and anti-Ro60 antibodies varied among enrolled patients. Significant differences were detected in the general information, clinicalsymptoms, cytokines, immunoglobulins, complements and autoantibodies between groups (P<0.05). Compared with females, the incidence of ILD increased by 56.7% in males. The risk of ILD increased by 3.8% for each additional year of age. Patients in the anti-Ro52+anti-Ro60- group had a higher risk of ILD than those in other groups. Conclusion Positivity for anti-Ro52 antibody, male and old age are independent risk factors for ILD in CTD patients. Anti-Ro52 and anti-Ro60 antibodies have a complicated role in CTD, both of which should be used to replace the detection of traditional anti-SSA antibodies as independent variables to be examined.
