Abstract

objective and designsystemic-Inflammatory-autoimmune-diseases (SIAD) is increasingly considered in myelodysplastic-syndromes (MDS). In this line, we evaluated the MDS auto-immunological profile, correlating it to the mutational landscape, trying to identify a molecular-genetic trigger agent related to SIAD.Methods and materialsEighty-one MDS were enrolled and t-NGS was performed. anti-nuclear-antibodies (ANA) were tested, and ANA-antigenic-specificity was characterized by ANA-profile, ENA-screen, anti-dsDNA. non-hematological-patients (NHP) and healthy-donors (HD) were used as controls. results at clinically relevant cut-off (& GE; 1:160), ANA was significantly more frequent in MDS, while ANA-antigenic-specificity showed a low association rate. ANA & GE; 1:160-positive MDS showed a mutational landscape similar to ANA-negative/ANA < 1:160 MDS. no significant correlations between mutational and immunological profiles were found and UBA1 mutations, related to VEXAS, were absent.conclusionsAlthough ANA-positivity was found to be increased in MDS, the low ANA-antigenic-specificity suggests that autoantibodies didn't recognize autoimmune-pathognomonic antigens. the lack of relationship between genetic profile and ANA-positivity, suggests that MDS genetic variants may not be the direct cause of SIAD.
