Patients were divided into the pSS-ILD (102 cases) and pSS-non-ILD groups (154 cases) based on the presence or absence of ILD on high-resolution computed tomography (HRCT). Demographics information, clinical symptoms, laboratory indicators and HRCT features were compared, and the logistic regression analysis was utilized to identify the risk factors.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p>A total of 256 patients were included. Patients with pSS-ILD were more often female, and their age and disease duration were significantly higher than those in the pSS-non-ILD group (<jats:italic>p<\/jats:italic> &amp;lt; 0.05). The HRCT imaging classification included ground glass-like shadow (78.4%) and patchy solid shadow (17.6%), and Non-specific interstitial pneumonitis (NSIP) (72.5%) was the predominant typology. Regarding the laboratory indexes, the positive rates of erythrocyte sedimentation rate, C-reactive protein, white blood cell count, neutrophil\/lymphocyte ratio, triglycerides, total cholesterol, and anti-SS-A52 antibodies were significantly higher in the pSS-ILD patients than in the pSS-non-ILD group, while the positive rates of anti-synaptic antibodies were lower than in the pSS-non-ILD group, and the differences between two groups were statistically significant (<jats:italic>p<\/jats:italic> &amp;lt; 0.05). Logistic regression showed that age &amp;gt;60\u00a0years, longer duration of disease, higher triglycerides, and cholesterol were risk factors for pSS-ILD patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion:<\/jats:title><jats:p>The clinical features of pSS-ILD patients were xerophthalmia, cough and shortness of breath, and HRCT can help to diagnose the disease at an early stage. Age over 60\u00a0years, chronic course of disease, and elevated lipid levels are risk factors for ILD in pSS patients, and the relationship between autoimmune antibody levels and the occurrence of ILD needs to be further confirmed in follow-up studies with large sample sizes. These findings have the potential to provide useful information for early diagnosis, treatment, and prevention of the development of pSS-ILD.<\/jats:p><\/jats:sec>","DOI":"10.3389\/abp.2024.12461","type":"journal-article","created":{"date-parts":[[2024,4,5]],"date-time":"2024-04-05T16:11:53Z","timestamp":1712333513000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":5,"title":["Clinical features and risk factors for primary Sj\u00f6gren\u2019s syndrome combined with interstitial lung disease: a retrospective study"],"prefix":"10.3389","volume":"71","author":[{"given":"Zhixia","family":"Yang","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hao","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lei","family":"Shan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dan","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2024,4,2]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"326","DOI":"10.1093\/rheumatology\/34.4.326","article-title":"Cytokine mRNA expression in the labial salivary gland tissues from patients with primary Sjogren's syndrome","volume":"34","author":"Boumba","year":"1995","journal-title":"Rheumatology"},{"key":"B2","doi-asserted-by":"publisher","first-page":"rky002","DOI":"10.1093\/rap\/rky002","article-title":"Distinctive clinical phenotype of anti-centromere antibody-positive diffuse systemic sclerosis","volume":"2","author":"Caetano","year":"2018","journal-title":"Rheumatology Adv.
