Abstract
BACKGROUND: We conducted a monocentric retrospective study of patients with myelodysplastic syndromes (MDS) and autoimmune or inflammatory disorders (AIMs) and a literature review. We analyzed the association with subgroups of the WHO 2016 MDS classification and patient's survival in a case control study. Risk factors associated with survival were analyzed by uni- and multivariate analysis. RESULTS: From all MDS patients 11% presented with AIMs. These were heterogeneous and the most frequent where polyarthritis (25%) and autoimmune cytopenias (17%). No difference for frequency and type of AIMs was observed for the WHO 2016 MDS subgroups (p = .3). In the case control study WHO classification, karyotype abnormalities, IPSS-R and IPSS were similar in both groups. The overall survival from MDS diagnosis was better in the group with AIMs [10.3 ± 0.6 (IC95% 6.2-12.9) versus 4.8 ± 1.1 years (IC95% 4.2-8.7), p = .04]. The better survival was restricted to MDS with low or intermediate-1 IPSS [11.1 ± 1.5 (IC95% 9.9-NR) versus 8.7 ± 1.3 years (IC95% 4.8-10.3), p = .006]. The better survival was only observed when AIMs diagnosis was timely associated or appeared after MDS diagnosis (p = .04). Factors associated with a better overall survival and survival without AML were steroid dependence [respectively HR = 0.042, p = .003, (IC95% 0.005-0.33) and HR = 0.07, p = .002, (IC95% 0.013-0.39)], a diagnosis of AIMs and MDS timely associated [respectively HR = 0.05, p = .009, (IC95% 0.006-0.478) and HR = 0.1, p = .008, (IC95% 0.018-0.54)] or a diagnosis of AIMs after MDS [respectively HR = 0.024, p = .009, (IC95% 0.001-0.39) and HR = 0.04, p = .008, (IC95% 0.003-0.43)]. CONCLUSION: Autoimmune and inflammatory diseases associated to MDS are heterogeneous. AIMs diagnosed after or concomitantly to MDS seems associated with a better survival. Prospective studies are necessary to demonstrate that autoimmunity is associated to a better control of the MDS clone.
