Thirty patients of myelodysplastic syndrome (MDS) were treated over a period of 2 yr using 3 different treatment regimens. Twelve patients received hydroxyurea, 4 were given low dose cytosine arabinoside and 14 others were treated with an aggressive acute myeloid leukaemia (AML) induction regimen. A low complete remission was obtained in the first 2 groups (17 and 25% respectively), whereas 9 (64%) patients attained complete remission with the AML induction regimen. Remission in the latter group was associated with prolonged and severe pancytopenia requiring intensive support. Patients in all the 3 groups had a short duration of remission culminating in death with progressive marrow failure or evolution to AML, indicating the limitations of the current treatment strategies for MDS and highlighting the need for exploring newer therapeutic approaches.

Objective: To evaluate the short-term efficacy and safety of eculizumab for the treatment of paroxysmal nocturnal hemoglobinuria (PNH) in China.
Method: Data were retrospectively collected from patients with PNH who received at least 3 months of full-dose eculizumab. Changes in clinical and laboratory indicators after 1, 3, and 6 months of eculizumab therapy and at the end of follow-up were documented.

Myelodysplastic syndrome (MDS) is a heterogeneous clonal disorder characterized by insufficient hematopoiesis, peripheral blood cytopenia and an increased risk for malignant transformation to acute myeloid leukemia. Several factors, such as age, sex and lifestyle, promote the development of MDS syndrome. Oxidative stress, along with its detrimental effects, cause hematological disorders; however, its role in the pathogenesis of MDS is unknown.

Myelodysplastic Syndromes (MDS) represent a group of heterogeneous myeloid clonal diseases derived from aberrant hematopoietic stem/progenitor cells. Enhancer of zeste homolog 2 (EZH2) is an important regulator in gene expression through methyltransferase-dependent or methyltransferase-independent mechanisms. Herein, we found EZH2 inhibition led to MDS cell pyroptosis through RNA Helicase A (RHA) down-regulation induced overexpression of S100A9, a key regulator of inflammasome activation and pyroptosis.
