Introduction: A subset of patients with MDS and related myeloid disorders present with concomitant autoimmune rheumatological diseases (AIRD); however the prevalence ranges from 10-48% based on limited literature. Further, use of immunosuppressive agents in AIRD patients could confound the secondary diagnosis of MDS and in some cases cause it (therapy-related myeloid neoplasm; t-MN). The prevalence of cytopenia in AIRD patients is unknown and the genetic characteristics of MDS patients with concomitant AIRD have not been described. Hence, we interrogated two large multi-institutional databases -Royal Adelaide Hospital Rheumatology Database (RAH-RD) and South-Australian MDS (SA-MDS) registry in this study. Methods: Demographic, clinical, laboratory and treatment data of 2663 AIRD and 1157 MDS patients were analysed. In AIRD patients (autoimmune inflammatory arthritis, spondyloarthritis, vasculitis and connective tissue diseases), cytopenia (persisting >6 months) were defined as follows: hemoglobin
