Methods: Eighty-eight female patients with SjS and 3,338 age-matched healthy female controls were included in this study. 25 OH-D3 levels were compared with healthy controls. Then the patients were stratified according to their 25 OH-D3 levels, either insufficient/deficient or normal (<50 nmol/L or ≥50 nmol/L). The disease activity was evaluated using The EULAR SjS disease activity index (ESSDAI) and its components. Correlation analyses were also performed for a possible correlation with disease characteristics and markers of activity. Results: No differences in 25 OH-D3 levels were found between SjS and healthy populations (p>0.05). No correla- tions were found between patient characteristics or labo- ratory values (p>0.05). Conclusions: This study did not find a link between disease characteristics and disease activity and 25 OH-D3 levels. Prospective studies with more patients should be conducted to reach a conclusion.eninfo:eu-repo/semantics/openAccess25 OH-D3 LevelsDisease ActivitySjögren SyndromeVitamin DPrimary Sjögren's-SyndromeVitamin-D LevelsDisease-ActivityAssociationDeficiencyEssdai25-Hydroxyvitamin Levels in Sjögren’s Syndrome: Is It the Right Time to Dismiss the Case or NotArticle10.1515/tjb-2023-02732-s2.0-85205147173
