Systemic lupus erythematosus (SLE) is an autoimmune disease with multisystem involvement and most commonly affects women of childbearing age. Most of the patients, if not all, have positive antinuclear antibody (ANA) in their serum. ANA-negative SLE is extremely rare.

: To explore the potential association between positive ANA serology and all-cause mortality in a large cohort of patients, including those with and without rheumatological conditions and other immune-related diseases. : A retrospective cohort study analyzed all-cause mortality among 205,862 patients from Clalit Health Services (CHS), Israel's largest health maintenance organization (HMO). We compared patients aged 18 and older with positive ANA serology (n = 102,931) to an equal number of ANA-negative controls (n = 102,931).

Background/objectives: Systemic autoimmune rheumatic diseases (SARDs) pose diagnostic challenges, particularly in pediatric populations, due to their diverse presentations and overlapping symptoms. This study aimed to evaluate the diagnostic concordance between indirect immunofluorescence (IIF) at different dilution levels (1/80 and 1/640) and immunoblot findings for anti-centromere antibody (ACA) positivity. Additionally, the clinical significance of ACA positivity and its association with SARDs in pediatric patients was assessed.
