Abstract:

Objective To analyze the clinical characteristics and risk factors of the patients with primary Sjogren’s syndrome (pSS) complicated with interstitial lung disease (ILD), and to improve the clinicians’understandings of the disease, and to provide the evidence for the early detection of extradular organ involvement by the clinicians. Methods The clinical characteristics of 176 patients with pSS were collected and were divided into pSS complicated with ILD group (n=21) and pSS complicated without ILD group (n=155) according to whether the patients were complicated with ILD.The levels of hemoglobin (Hb), white blood cells (WBC), platelets (PLT), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR),rheumatoid factor (RF),immunoglobulin G (IgG),immunoglobulin M (IgM),immunoglobulin A (IgA), complement 3 (C3), complement 4 (C4), and the positive rates of granular type antinuclear antibodies, cytoplasmic granular type antinuclear antibodies, homogeneous type antinuclear antibodies, anti-SSA, anti-SSB, and anti-Ro-52 antibodies of the patients in two groups were compared.Univariate and multivariate Logistic regression analysis were used to analyze the clinical characteristics and laboratory indexes of the pSS patients complicated with ILD. Results Among the 176 pSS patients, the ratio of male to female was 1∶28, with the median age of 49 (39-58) years and the median course of 24 (24-48) months. Compared with pSS complicated without ILD group,the age of the patients in ILD group was older (P<0.01), and the level of ESR was increased(P<0.01),the positive rates of cytoplasmic granular type antinuclear antibody and anti-Ro-52 antibody were increased (P<0.01). The multivariate Logistic regression analysis results showed that the increasing of ESR level (OR=1.046,95% CI: 1.026-1.066, P=0.001) and positive granulosa type (OR=4.676,95% CI: 1.156-18.916, P=0.031) were the risk factors for ILD complicated with pSS. Conclusion The patients with pSS complicated by ILD have an older onset age and higher ESR levels; ILD is more likely to occur when the cytoplasmic granular type antinuclear antibody and anti-Ro-52 antibody of the patients are positive; the increasing of the ESR level and positive coated granular type antinuclear antibody are the risk factors for the pSS complicated with ILD.
