Abstract

Abstract : Background: Systemic inflammatory and autoimmune manifestations (SIAMs) are frequently reported in Myelodysplastic syndromes (MDS). Studies focused on the impact of SIMAs on survival outcomes of MDS remains controversial. We performed this systematic review and meta-analysis to determine the association of SIAMs with overall survival, median survival, rate of acute myeloid leukemia transformation and mortality of MDS. Materials and methods: An electronic search was conducted in 4 databases without any language restrictions, including PubMed, EMBASE, Medicine and Cochrane library up to April 30, 2021. Results: The 18 studies included a total of 4603 MDS patients, of which 1175 (25.5%) patients had SIAMs. MDS patients with SIAMs had a statistically shorter overall survival compared with patient without SIAMs (Hazard ratio, 2.43; 95% confidence interval [CI], 1.34–4.41; P < .01). Our results were most compatible with no effect of SIAMs on median survival, rate of acute myeloid leukemia transformation and mortality (Median survival ratio, 1.16; 95% CI, 0.91–1.47; Odds ratio, 0.96; 95% CI, 0.63–1.45 and 1.2; 95% CI, 0.84–1.7, respectively). Conclusion: In this systematic review and meta-analysis, SIAMs appeared to have an adverse effect on overall survival of MDS patients. This finding suggested that SIAMs may be a potential independent prognostic factor for MDS.
