Key findings included: The primary endpoint of transfusion independence over 8 weeks during weeks 1 to 24 of the study was met in 38% of luspatercept-treated patients compared with 13% in the placebo arm ( P <0.001). Sideroblastic anemia (SA) includes a group of inherited and acquired anemias of ineffective erythropoiesis characterized by an accumulation of ring sideroblasts (RS) in the bone marrow and decreased production of mature red blood cells. 1 Ring sideroblasts are nucleated erythroblasts with a pathologic accumulation of iron granules in the mitochondrial matrix.

Y1 - 2018/1/1 §Ring sideroblasts ≥ 15% were present in 142 (71.7%) of 198 sequenced patients with gene mutation data (see text for SF3B1 gene mutation incidence). RBC Transfusion Independence The proportion of patients who achieved RBC-TI ≥ 8 weeks was significantly higher in the lenalidomide group (26.9%) than in the placebo group (2.5%; Fisher exact P < .001; Table 2 ). 2016-01-01 · The accurate classification of 5q minus syndrome with a JAK2 V617F mutation is yet not determined, especially in patients with additional presence of ring sideroblasts. The case described above responded well to the treatment with lenalidomide, which is commonly seen in patients with isolated 5q minus deletion MDS but much less often in patients with other types of low grade MDS [9] , [13] .
