Sustained Erythroid Response Associated With Red Cell Transfusion and Progressive Growth Factor Independence Is Feasible With Adjuvant Sertraline In Low-Risk Myelodysplastic Syndrome (LR-MDS)

TL;DRAbstract

Abstract Background LR-MDS is a heterogeneous group of clonal marrow disorder associated with ineffective hematopoeisis and complex genomic etiology. For patients (pt) with refractory cytopenia phenotype (RC-P), transfusion and growth factor support, such as Erythropoietin Stimulating Agents (ESAs) and Granulocyte Colony Stimulating Factor (G-CSF), are treatment options. Response rates for ESA is about 30%, (and response potentiation can be achieved in about 35% of pt receiving concurrent G-CSF.However, ESA unresponsiveness is a common phenomenon and is associated with transfusion dependence, normal/high EPO levels, and high IPSS score. Therefore, novel therapies are greatly needed. Biologically, LR-MDS is linked to deregulation of apoptosis and cytokine signaling pathways. Selective Serotonin Reuptake Inhibitors (SSRIs) can induce normalization of deranged cytokines such as IL6 and TNF-α in clinical depression. In animal model of arthritis, sertraline abrogates manifestation of autoim
