    ObjectiveThe main purpose of this study was to investigate the current situation of primary Sjögren's syndrome (pSS) patients with interstitial lung disease (ILD) in China. The relationships between social demography, disease activity, psychological status, clinical variables, and ILD were analyzed. Besides that, the quality of life (QoL) in pSS with ILD was also analyzed.MethodsIn the cross-sectional study, 101 pSS patients participated in this study. Under the guidance of the researchers, the European League Against Rheumatism Sjögren's Syndrome Disease Activity Index (ESSDAI), EULAR Sjögren's Syndrome Patient-Reported Index (ESSPRI), the Short-Form 36 health survey (SF-36), Hospital Anxiety and Depression Scale (HADS), Pittsburgh sleep quality index (PSQI), Summated Xerostomia Inventory (SXI), and other related questionnaires were completed. Independent sample t tests, Mann-Whitney U test, chi-square test, and correlational analysis were used.ResultsThe data showed that 28 (30.1%) pSS people with ILD. The occurrence and development of ILD were associated with disease duration, fatigue, alanine aminotransferase (ALT), neutrophils, albumin, and use of hormone. The survey also found that the QoL of pSS-ILD was significantly lower than non-ILD, especially the score in the dimension of role physical function.ConclusionsILD was very common in pSS. ILD had a significant negative impact on the QoL of patients. Therefore, it is of great significance to strengthen the early intervention and drug treatment of pSS patients to prevent ILD and improve their QoL.Key Points• This cross-sectional study finds that the incidence of ILD in patients with pSS is 30.1%.• The occurrence and development of ILD is associated with disease duration, fatigue, alanine aminotransferase (ALT), neutrophils, albumin, and use of hormone.•The study also finds that the QoL of pSS-ILD is significantly lower than in patients with non-ILD, especially the score in the dimension of role physical function.
