Abstract
Race and ethnic backgrounds affect the disease characteristics and clinical outcomes in many cancers, including acute myeloid leukemia; however, the association of race/ethnicity on myelodysplastic syndrome (MDS) is still controversial. Therefore, we aimed to study the impact of race/ethnicity on the disease characteristics and survival outcomes in patients with MDS. Adult patients with MDS diagnosed in 2004-2016 were selected using the SEER database. Race/ethnicity was categorized as non-Hispanic White (NHW), non-Hispanic Black (NHB), and Hispanic. Hispanic and NHB patients had significantly lower incidence rate ratio (IRR) in age group ≥01 years (p < .001) compared to NHW; however, in the age group <50 years, NHB patients had significantly higher IRR with an increased incidence rate of 49%. NHB patients had better overall survival than Hispanic and NHW patients (p < .001), even after adjusting for confounding variables. MDS have significant differences in age at diagnosis, disease risk, and survival outcomes based on racial/ethnic backgrounds.

Menatetrenone facilitates hematopoietic cell generation in a manner that is dependent on human bone marrow mesenchymal stromal/stem cells. Int J Hematol 2020; 112:316-330. [PMID: 32572826 DOI: 10.1007/s12185-020-02916-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2020] [Revised: 06/06/2020] [Accepted: 06/11/2020] [Indexed: 12/24/2022]
Abstract
Vitamin K2 in the form of menatetrenone has clinical benefits for osteoporosis and cytopenia. Given the dominant role of mesenchymal-osteolineage cells in the regulation of hematopoiesis, we investigated whether menatetrenone alters the hematopoiesis-supportive capability of human bone marrow mesenchymal stromal/stem cells (BM-MSCs). Menatetrenone up-regulated fibronectin protein expression in BM-MSCs without affecting their proliferation and differentiation capabilities. In addition, menatetrenone treatment of BM-MSCs enhanced generation of the CD34+ cell population in co-cultures through acceleration of the cell cycle. This effect was associated with cell-cell interactions mediated by VLA-4 and fibronectin. This proposal was supported by cytokine array and quantitative real-time PCR analyses, in which there were no significant differences between the expression levels of hematopoiesis-associated soluble factors in naïve and menatetrenone-treated BM-MSCs. Profiling of hematopoietic cells in co-cultures with menatetrenone-treated BM-MSCs demonstrated that they included significantly more CD34+CD38+ hematopoietic progenitor cells and cells skewed toward myeloid and megakaryocytic lineages than those in co-cultures with untreated BM-MSCs. Notably, myelodysplastic syndrome-derived cells were induced to undergo apoptosis when co-cultured with BM-MSCs, and this effect was enhanced by menatetrenone. Overall, our findings indicate that pharmacological treatment with menatetrenone bestows a unique hematopoiesis-supportive capability on BM-MSCs, which may contribute to the clinical improvement of cytopenia.

Abstract
BACKGROUND AND AIM Peripheral cytopaenias and dyspoiesis are common in cirrhosis; however, the prevalence of dyspoiesis and its contribution in cirrhosis-related cytopaenias has not been studied. We aimed to study the bone marrow (BM) dyspoiesis and its impact on peripheral blood cell counts and refractory anaemia in patients with cirrhosis. PATIENTS AND METHODS We reviewed all the BM aspirates and biopsies of cirrhotic cases, done from 2011 to 2018 for clinical indications. Dyspoiesis was considered if >5% of the precursor cells of any of the three lineages showed dyspoietic changes. Primary haematological or non-haematological malignancies, chronic kidney disease, drug intake, acute and chronic hepatitis and granulomatous disease were excluded. RESULTS Of 608 these, 82 cases (13.5%) showed dyspoiesis in the BM precursors. There was no difference in age (p=0.16), gender (p=0.58) and spleen size (p=0.35) in cases with or without dyspoiesis. Majority of the cases had dyspoiesis in erythroid series (62, 75.6%) and megakaryocytes (15, 18.2%). Dyspoiesis was more prominent in alcoholics 44 cases (53.6%) and autoimmune diseases 13 cases (15.8%). Erythroid hyperplasia (47.7±14.4 vs 40±11.1; p<0.001) was more in cases with dyserythropoiesis, indicating ineffective erythropoiesis. Patients with dyspoiesis had lower haemoglobin (7.5±1.9 vs 9.3±2.2 g/dL, p<0.001). 54 (8.07%) had refractory anaemia with dyspoiesis present in 48 (88.8%) (p<0.01). Dyspoiesis was independently associated with refractory anaemia when adjusted for age, gender, aetiology and liver disease severity. CONCLUSIONS BM dyspoiesis, especially dyserythropoiesis, is associated with severe refractory anaemia in patients with cirrhosis and requires new therapeutic approaches.

Abstract
Myelodysplastic syndromes are a heterogeneous group of clonal hematopoietic disorders. However, the therapies used against the hematopoietic stem cells clones have limited efficacy; they slow the evolution toward acute myeloid leukemia rather than stop clonal evolution and eradicate the disease. The progress made in recent years regarding the role of the bone marrow microenvironment in disease evolution may contribute to progress in this area. This review presents the recent updates on the role of the bone marrow microenvironment in myelodysplastic syndromes pathogenesis and tries to find answers regarding how this information could improve myelodysplastic syndromes diagnosis and therapy.

Pharmacol Res Perspect 2016; 4:e00206.

Abstract
Resistance to azacitidine is a major issue in the treatments of myelodysplastic syndrome and acute myeloid leukemia, and previous studies suggest that changes in drug metabolism are involved in the resistance. Therefore, drugs with mechanisms resistant or alternative to such metabolic changes have been desired for the treatment of resistant disease. We generated azacitidine‐resistant cells derived from SKM‐1 and MOLM‐13 leukemia cell lines in vitro, analyzed the mechanisms, and examined the impact on the efficacy of other antimetabolic drugs. It appeared that the cell growth‐inhibitory effect of azacitidine, expression levels of uridine–cytidine kinase 2, and the concentrations of azacitidine triphosphate were remarkably decreased in the resistant cells compared with those in parent cells. These results were consistent with previous observations that azacitidine resistance is derived from metabolic changes. Cross‐resistance of greater than 10‐fold (shift in IC50 value) was observed in azacitidine‐resistant cells for decitabine and for cytarabine, but not for gemcitabine or the inosine‐5′‐monophosphate dehydrogenase (IMPDH) inhibitors FF‐10501 and mycophenolate mofetil (cross‐resistance to 5‐fluorouracil was cell line dependent). The IMPDH inhibitors maintained their cell growth‐inhibitory activities in the azacitidine‐resistant cell lines, in which the levels of adenine phosphoribosyltransferase (which converts FF‐10501 to its active form, FF‐10501 ribosylmonophosphate [FF‐10501RMP]), FF‐10501RMP, and the target enzyme, IMPDH, were equivalent to those in the parent cell lines. These results suggest that an IMPDH inhibitor such as FF‐10501 could be an alternative therapeutic treatment for leukemia patients with acquired resistance to azacitidine.

Abstract
Background: Accurate prediction of a patient's prognosis is useful to define the risk posed by the disease. Age, gender, peripheral blood cytopenia, proportion of bone marrow (BM) blasts, performance status, comorbidities, transfusion dependence, specific karyotype abnormalities and molecular biomarkers can refine the prediction of prognosis in MDS. Aim: to assess the influence of the some prognostic factors like age, gender, cytopenia, BM blast percentage, transfusion dependence, ferritin, hemoglobin (Hb), lactate dehydrogenase (LDH), albumin and specific karyotype abnormalities in myelodysplastic syndromes on overall survival (OS). Patients and methods: we retrospectively analyzed the cohort of 108 patients diagnosed between 1.1.2011 and 31.12.2013 at the University Clinic of Hematology, Ss Cyril and Methodius University, Skopje, Macedonia. They were evaluated for clinical and hematologic features at diagnosis and at leukemic transformation. Results: in the study group 62 were man and 46 women. Male to female ratio was 1.35 to 1. The differences in OS between men and women were significant (p = .03015). The mean age at diagnosis was 66,6 years. According to the age OS was 16,4 months. FAB subtypes influenced OS significantly (p = .03015). OS inversely correlated with BM blast percentage (p= .02327). Cytopenia had no impact on OS (p=.33755). Hb as a whole and groups with different levels of Hb had no influence on OS (p = .12142) and (p= .07535), respectively. The group with ferritin <500 µg/L had better OS (p=.04720). Transfusion dependence, LDH and albumin had no impact on OS. Leukemic transformation was noticed in 10 (9,3%) patients. Mortality was 36,1%. Conclusion: gender, FAB subtypes, BM blast percentage and the serum levels of ferritin had an influence on OS, while age, hemoglobin level, transfusion dependence, LDH and albumin had no impact on OS.

Trend (1999-2009) in U.S. death rates from myelodysplastic syndromes: utility of multiple causes of death in surveillance. Cancer Epidemiol 2013; 37:569-74.

Abstract
BACKGROUND For myelodysplastic syndromes (MDS) (formerly known as preleukemia), a diverse group of myeloid neoplasms usually involving anemia in elderly persons, trends in U.S. death rates apparently have not been reported. METHODS Trends in annual age-standardized rates per 100,000 from 1999 to 2009 were examined for MDS using multiple causes vs. underlying cause alone, coded on death certificates for U.S. residents. RESULTS The death rate (all ages combined) for MDS increased from 1999 to 2009, from 1.62 to 1.84 using underlying cause alone and from 2.89 to 3.27 using multiple causes. Rates using multiple causes were about 80% higher than those based on underlying cause alone. From 2001 to 2004 the rate for MDS using underlying cause alone (but not using multiple causes) declined, accompanied by an increase in the rate for deaths from leukemia as underlying cause with mention of MDS; this trend coincided with the advent of the 2001 World Health Organization's reclassification of certain MDS as leukemia. The MDS rate for age 65+ years increased after 2005, whereas the rate for age 25-64 years was low but declined from 2001 to 2003 and then stabilized. For deaths with MDS coded as other than underlying cause, rates did not decline for deaths from each of the two most common causes (i.e., cardiovascular diseases and leukemia). CONCLUSIONS Evidence for decreases in MDS-related mortality rates was limited; the increase at age 65+ years is consistent with increases in incidence rates reported from cancer registries. Using multiple causes of death vs. only the underlying cause results in substantially higher MDS-related death rates, shows the impact of changes in the classification of myeloid neoplasms and emphasizes the importance of reducing cardiovascular disease mortality in MDS patients.

Abstract
Myelodysplastic syndromes (MDS) represent a heterogeneous group of clonal hematologic neoplasms characterized by morphologic dysplasia, aberrant hematopoiesis and peripheral blood refractory cytopenias. MDS is recognized to be associated with an increased risk of symptomatic anemia, infectious complications and bleeding diathesis, as well as a risk of progression to acute myeloid leukemia, particularly in patients with a high IPSS score. The advent of use of hematopoietic growth factors such as granulocyte colony-stimulating factor (G-CSF) and recombinant erythropoietin (EPO) has improved symptoms in MDS patients in addition to some data that suggest there might be an improvement in survival. G-CSF is an effective therapeutic option in MDS patients, and it should be considered for the management of refractory symptomatic cytopenias. G-CSF and EPO in combination can improve outcomes in appropriate MDS patients such as those with lower-risk MDS and refractory anemia with ring sideroblasts (RARS) . This article reviews use of growth factors for lower-risk MDS patients, and examines the data for G-CSF, EPO and thrombopietic growth factors (TPO) that are available or being developed as therapeutic modalities for this challenging disease.
