This analysis identifies genetic variants and immunological traits in patients with secondary sjögren’s syndrome, suggesting overlaps between lupus and scleroderma.
Key Points
Positive antinuclear factors were found in all SLE-sSS and 75% of SSc-sSS patients, indicating a strong autoimmune response.
Autoantibodies SS-A/Ro60 and SS-A/Ro52 more frequently appeared in both groups, while SS-B antibodies were less common, suggesting key biomarkers.
Whole-exome sequencing revealed likely pathogenic variants related to autoimmunity, highlighting the need for further genetic research.
Findings emphasize the necessity for larger studies due to limitations like small sample size and the cross-sectional nature of the research.
