Expression and function of leptin receptor isoforms in myeloid leukemia and myelodysplastic syndromes: proliferative and anti-apoptotic activities. (1/1945)

The receptor for the gene product of the obesity gene, leptin, was recently reported to be expressed on murine and human hematopoietic progenitor cells. Therefore, we studied the expression of the leptin receptor, OB-R, in normal myeloid precursors, human leukemia cell lines, and primary leukemic cells using reverse-transcriptase polymerase chain reaction. In normal hematopoiesis, OB-R was expressed in CD34(+) cells. Normal promyelocytes (CD34(-)33(+) and CD34(-)13(+)) expressed only very low levels of the short, presumably nonsignaling isoform. Both the long and short isoforms of OB-R were expressed in 10 of 22 samples from patients with newly diagnosed primary or secondary acute myeloid leukemia (AML), with a higher incidence of the long isoform in primary AML (87.6% v 28.6%; P =.01). The incidence of OB-R expression was higher in recurrent than in newly diagnosed AML (P <.001), and samples from four patients with refractory AML showed strong expression of both isoforms. Both OB-R isoforms were also expressed in newly diagnosed and recurrent acute promyelocytic leukemia cells but were essentially absent in samples of chronic or acute lymphocytic leukemia. In vitro growth of myeloid leukemic cell lines and of blasts from 14 primary AMLs demonstrated that recombinant human leptin alone induced low level proliferation, significantly (P <.05) increased proliferation induced by recombinant human granulocyte colony-stimulating factor, interleukin 3, and stem cell factor in a subset of AML and increased colony formation (P <.005). Also, leptin reduced apoptosis induced by cytokine withdrawal in MO7E and TF-1 cells. Serum leptin levels correlated only with body mass index (P <. 001) and gender (P =.03). Results confirm the reported expression of leptin receptor in normal CD34(+) cells and demonstrate the frequent expression of leptin receptors in AML blasts. While normal promyelocytes lack receptor expression, leukemic promyelocytes express both isoforms. We also demonstrate proliferative effects of leptin alone and in combination with other physiologic cytokines, and anti-apoptotic properties of leptin. These findings could have implications for the pathophysiology of AML.  (+info)

Bone marrow transplantation in pediatric patients with therapy-related myelodysplasia and leukemia. (2/1945)

Eleven children underwent BMT for therapy-related MDS or leukemia, four from HLA-identical siblings and seven from unrelated donors. Ten of the 11 were conditioned with busulfan and cyclophosphamide as the majority had received prior irradiation to the chest and/or abdomen. All patients engrafted. Regimen-related toxicity was more common when compared to historical controls. Eight patients developed acute GVHD and four of eight who survived 100 days post transplant developed extensive chronic GVHD. Non-relapse related mortality occurred in three patients. Five patients developed recurrent malignancy: one died from recurrence of osteosarcoma, three died of recurrent leukemia or MDS and another developed two subsequent malignancies (duodenal carcinoma and anaplastic astrocytoma). Three survive disease-free at 14+, 22+ and 43+ months for a 2 year actuarial cancer-free survival of 24% (95% confidence interval = 5-53%). Although allogeneic BMT can be curative, regimen-related toxicity is frequent and recurrent malignancy remains the major obstacle.  (+info)

'Common' uncommon anemias. (3/1945)

Of the uncommon anemias, "common" types include the anemia of renal disease, thalassemia, myelodysplastic syndrome and the anemia of chronic disease. These conditions may be suggested by the clinical presentation, laboratory test values and peripheral blood smear, or by failure of the anemia to respond to iron supplements or nutrient replacement. The principal cause of the anemia of renal disease is a decreased production of red blood cells related to a relative deficiency of erythropoietin. When treatment is required, erythropoietin is administered, often with iron supplementation. In the anemia of chronic disease, impaired iron transport decreases red blood cell production. Treatment is predominantly directed at the underlying condition. Since iron stores are usually normal, iron administration is not beneficial. Thalassemia minor results from a congenital abnormality of hemoglobin synthesis. The disorder may masquerade as mild iron deficiency anemia, but iron therapy and transfusions are often not indicated. In the myelodysplastic syndrome, blood cell components fail to mature, and the condition may progress to acute nonlymphocytic leukemia. The rate of progression depends on the subtype of myelodysplasia, but the leukemia is usually resistant to therapy.  (+info)

BACKGROUND: Accumulation of data regarding therapy-related leukemia (TRL) or myelodysplastic syndrome (t-MDS) is critical for assessing the risk of developing such diseases and for subsequent decision-making processes for better treatment. METHODS: We evaluated the clinical characteristics of patients with TRL/t-MDS diagnosed at the National Cancer Center Hospital between January 1989 and September 1997. This report is concerned with those patients who initially had been treated with chemotherapeutic agents for breast cancer. RESULTS: Thirteen patients (median age, 55 years) developed TRL (n = 4) or t-MDS (n = 9). The median interval between the development of TRL/t-MDS and initial treatment was 94 months (range 23-190 months). For the primary therapy, all patients had received intense and prolonged treatment with cyclophosphamide (CPA) and/or anthracyclines including doxorubicin (DOX), with a median cumulative dose of 55 g/body (range 16.4-288.5 g) for CPA and 480 mg/m2 (range 395-625.5 mg/m2) for DOX. Seven patients were subsequently treated by chemotherapy and one received an allogeneic bone marrow transplantation. CONCLUSIONS: Clinicians must remain alert to the risks associated with unproven medical practices which include long-term administration of alkylating agents. Selected patients with TRL/t-MDS may respond to intense salvage combination chemotherapy.  (+info)

Secondary leukemia or myelodysplastic syndrome after treatment with epipodophyllotoxins. (5/1945)

PURPOSE: The incidence of secondary leukemia after epipodophyllotoxin treatment and the relationship between epipodophyllotoxin cumulative dose and risk are not well characterized. The Cancer Therapy Evaluation Program (CTEP) of the National Cancer Institute (NCI) has developed a monitoring plan to obtain reliable estimates of the risk of secondary leukemia after epipodophyllotoxin treatment. METHODS: Twelve NCI-supported cooperative group clinical trials were identified that use epipodophyllotoxins at low (<1.5 g/m2 etoposide), moderate (1.5 to 2.99 g/m2 etoposide), or higher (> or =3.0 g/m2 etoposide) cumulative doses. Cases of secondary leukemia (including treatment-related myelodysplastic syndrome) occurring on these trials have been reported to CTEP, as has duration of follow-up for all patients, thereby allowing calculation of cumulative 6-year incidence rates of secondary leukemia for each etoposide dose group. RESULTS: The calculated cumulative 6-year risks for development of secondary leukemia for the low, moderate, and higher cumulative dose groups were 3.3%, (95% upper confidence bound of 5.9%), 0.7% (95% upper confidence bound of 1.6%), and 2.2%, (95% upper confidence bound of 4.6%), respectively. CONCLUSION: Within the context of the epipodophyllotoxin cumulative dose range and schedules of administration encompassed by the monitoring plan regimens, and within the context of multiagent chemotherapy regimens that include alkylating agents, doxorubicin, and other agents, factors other than epipodophyllotoxin cumulative dose seem to be of primary importance in determining the risk of secondary leukemia. Data obtained by the CTEP secondary leukemia monitoring plan support the relative safety of using epipodophyllotoxins according to the therapeutic plans outlined in the monitored protocols.  (+info)

The myelodysplastic syndromes: predictive value of eight prognostic systems in 143 cases from a single institution. (6/1945)

BACKGROUND AND OBJECTIVE: Despite the fact that several prognostic systems for myelodysplastic syndromes (MDS) have been proposed, few studies have been designed to test their effectiveness in independent patient populations. The aim of this study was to compare the prognostic value of 8 previously described prognostic systems in a series of consecutive MDS patients observed at a single institution over a 10-year period. DESIGN AND METHODS: One hundred and forty-three patients were diagnosed as having myelodysplastic syndrome (MDS) according to the French-American-British (FAB) criteria. They were studied retrospectively in order to assess the prognostic value of the FAB classification and 7 other prognostic systems. RESULTS: On the basis of data at diagnosis, all investigated systems effectively stratified patients into groups with different life expectancies and identified a subset of patients with poor clinical outcome. However, the systems had different outcomes concerning median survival of patients classified as low-risk, ranging from less than 3 years for the Mufti scoring system to more than 8 years for the FAB classification modified according to Rosati et al. Moreover, patient distribution into different risk categories was quite different with the different prognostic systems. INTERPRETATION AND CONCLUSIONS: When applied to our case series, some of the prognostic systems had a much lower prognostic value than in the patient population from which they derived. This evidence suggests that testing of prognostic systems in independent case series is necessary before using the systems in clinical practice.  (+info)

An unusual cutaneous manifestation of myelodysplastic syndrome: "pseudo-Koebner phenomenon". (7/1945)

An unusual and hitherto unreported complication of myelodysplastic syndrome is reported: the "pseudo-Koebner phenomenon." The skin lesions were characterised by exuberant "fleshy" masses at the sites of intravenous cannulation and skin trauma, and by histological evidence of chronic inflammation with focal necrosis and abscess formation. No evidence of dermal infiltration by malignant haemopoietic cells was seen. The exact aetiopathology of the phenomenon is unclear but an inappropriate and exaggerated inflammatory response owing to aberrant mediator mechanisms that are known to occur in some cases of myelodysplastic syndrome may be implicated.  (+info)

Randomized phase II study of fludarabine + cytosine arabinoside + idarubicin +/- all-trans retinoic acid +/- granulocyte colony-stimulating factor in poor prognosis newly diagnosed acute myeloid leukemia and myelodysplastic syndrome. (8/1945)

Preclinical data suggest that retinoids, eg, all-trans retinoic acid (ATRA), lower concentrations of antiapoptotic proteins such as bcl-2, possibly thereby improving the outcome of anti-acute myeloid leukemia (AML) chemotherapy. Granulocyte colony-stimulating factor (G-CSF) has been considered to be potentially synergistic with ATRA in this regard. Accordingly, we randomized 215 patients with newly diagnosed AML (153 patients) or high-risk myelodysplastic syndrome (MDS) (refractory anemia with excess blasts [RAEB] or RAEB-t, 62 patients) to receive fludarabine + ara-C + idarubicin (FAI) alone, FAI + ATRA, FAI + G-CSF, or FAI + ATRA + G-CSF. Eligibility required one of the following: age over 71 years, a history of abnormal blood counts before M.D. Anderson (MDA) presentation, secondary AML/MDS, failure to respond to one prior course of chemotherapy given outside MDA, or abnormal renal or hepatic function. For the two treatment arms containing ATRA, ATRA was given 2 days (day-2) before beginning and continued for 3 days after completion of FAI. For the two treatment arms including G-CSF, G-CSF began on day-1 and continued until neutrophil recovery. Patients with white blood cell (WBC) counts >50,000/microL began ATRA on day 1 and G-CSF on day 2. Events (death, failure to achieve complete remission [CR], or relapse from CR) have occurred in 77% of the 215 patients. Reflecting the poor prognosis of the patients entered, the CR rate was only 51%, median event-free survival (EFS) time once in CR was 36 weeks, and median survival time was 28 weeks. A Cox regression analysis indicated that, after accounting for patient prognostic variables, none of the three adjuvant treatment combinations (FAI + ATRA, FAI + G, FAI + ATRA + G) affected survival, EFS, or EFS once in CR compared with FAI. Similarly, there were no significant effects of either ATRA ignoring G-CSF, or of G-CSF ignoring ATRA. As previously found, a diagnosis of RAEB or RAEB-t rather than AML was insignificant. There were no indications that the effect of ATRA differed according to cytogenetic group, diagnosis (AML or MDS), or treatment schedule. Logistic regression analysis indicated that, after accounting for prognosis, addition of G-CSF +/- ATRA to FAI improved CR rate versus either FAI or FAI + ATRA, but G-CSF had no effect on the other outcomes. We conclude that addition of ATRA +/- G-CSF to FAI had no effect on CR rate, survival, EFS, or EFS in CR in poor prognosis, newly diagnosed AML or high-risk MDS.  (+info)

This study looks at response-based chemotherapy in treating newly diagnosed acute myeloid leukemia or myelodysplastic syndrome in younger patients with Down syndrome. Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Response-based chemotherapy separates patients into different risk groups and treats them according to how they respond to the first course of treatment. Response-based treatment may be effective in treating acute myeloid leukemia or myelodysplastic syndrome in younger patients with Down syndrome while reducing the side effects. ...

The proportion of attributable deaths varied according to a patients MDS risk status. The proportion of deaths attributable to MDS increased from 31.5% among low-risk patients to 48.8% in the intermediate-risk category and 74.1% of patients with high-risk MDS. CAD/stroke as the cause of death decreased from a high of 26.3% of patients with low-risk disease to 20.6% of patients with intermediate risk-MDS to 9.3% of patients with high-risk MDS.. Treatment of Myelodysplastic Syndrome. Lower-risk myelodysplastic syndrome patients are treated initially for the specific complications of the disease, such as anemia and low blood counts. If more aggressive therapy is needed, strategies that are considered standard of care include chemotherapy using hypomethylating agents (5-azacitidine and decitabine) and lenalidomide.. Higher-risk myelodysplastic syndrome patients usually need more aggressive therapy, but much depends on the age and condition of the patient. Younger patients with high-risk disease are ...

Azacitidine is the first agent to significantly prolong overall survival (OS) compared with conventional care regimens in patients with higher-risk myelodysplastic syndromes (MDS). Here, we review currently available data on azacitidine treatment in lower-risk MDS. In a phase III study, a subset of patients with lower-risk MDS treated with azacitidine achieved an overall response rate (ORR) of 60% and a longer median OS compared with supportive care (44 vs 27 months). In a phase II study investigating various azacitidine dose schedules, the

The term myelodysplastic syndrome (MDS) is used to describe a heterogeneous group of disorders that are characterized by clonal and ineffective hematopoiesis, morphological dysplasia, peripheral blood cytopenias and progressive bone marrow failure. MDS transforms to acute myeloid leukemia (AML) in approximately 30% of cases. Survival following a diagnosis of MDS varies from a few months to more than ten years (comparable to age/sex matched normal populations).1 This highly variable prognosis underscores the importance of a classification system, supplemented by a prognostic index, to predict the survival of patients with MDS and the likelihood of transformation to AML. With the recent development and introduction of several effective treatment options for MDS,2,3 the need for a classification system to predict responsiveness to treatment and clinical outcomes for individual patients has become even more important.. During the past 20 years, several MDS classification and prognostic scoring ...
Clinical trial for Myelodysplastic Syndromes , Bortezomib and Low Dose Cytarabine in the Treatment of High-Risk Myelodysplastic Syndromes
Perturbation in iron homeostasis is a hallmark of some hematologic diseases. Abnormal sideroblasts with accumulation of iron in the mitochondria are named ring sideroblasts (RS). RS is a cardinal feature of refractory anemia with RS (RARS) and RARS with marked thrombocytosis (RARS/-T). Mutations in SF3B1, a member of the RNA-splicing are frequent in RARS/-T and defects of this gene were linked to RS formation. Here we showcase the differences in iron architecture of SF3B1 mutant and wild type (WT) RARS/-T and provide new mechanistic insights by which

Herein, we demonstrated that TET2 expression increases during erytroid differentiation of primary hematopoietic progenitors from healthy donors and MDS patients. Pronier et al. [8] demonstrated that the TET2 silencing increased granulomonocytic differentiation in detriment of erythroid differentiation in normal CD34+ cells. Yan et al. [9], similarly demonstrated that TET2 inhibition led to MDS-like dyserythropoiesis. Of note, TET2 deletion leads to erythroid dysplasia and anemia in zebrafish model [14], suggesting a conserved function for TET2 in erythrocytes production.. Recently, Guo and colleagues [15] reported that TET2 mRNA levels was increased in mature erythroid cells from murine fetal liver, and in MEL and K562 cell lines upon chemically-induced erythroid differentiation. Using functional assays, the authors also established that TET2 plays a cytoprotective function in iron homeostasis against oxidative stress during erythropoiesis. In contrast, Inokura and colleagues [16], using cell ...
The myelodysplastic syndromes are a group of clonal hematopoietic stem cell diseases characterized by cytopenia(s), dysplasia in one or more cell lineages and increased risk of evolution to acute myeloid leukemia (AML). Recent advances in immunophenotyping of hematopoietic progenitor and maturing cells in dysplastic bone marrow point to a useful role for multiparameter flow cytometry (FCM) in the diagnosis and prognostication of myelodysplastic syndromes. In March 2008, representatives from 18 European institutes participated in a European LeukemiaNet (ELN) workshop held in Amsterdam as a first step towards standardization of FCM in myelodysplastic syndromes. Consensus was reached regarding standard methods for cell sampling, handling and processing. The group also defined minimal combinations of antibodies to analyze aberrant immunophenotypes and thus dysplasia. Examples are altered numbers of CD34(+) precursors, aberrant expression of markers on myeloblasts, maturing myeloid cells, monocytes ...
Antifungal prophylaxis with an oral triazole or parenteral echinocandin is recommended for patients who are at risk for profound, protracted neutropenia, such as most patients with acute myeloid leukemia/myelodysplastic syndromes or HSCT.

Additional distinctions between recommendations for invasive candidiasis and invasive mold infection are provided within the full text of the guideline (evidence-based; evidence quality: intermediate; strength of recommendation: moderate).. ...
Compared with World Health Organization-defined acute myeloid leukaemia (AML) not otherwise specified, patients with AML with myelodysplasia-related changes (AML-MRC) are generally older and more likely to have poor-risk cytogenetics, leading to poor response and prognosis. More than one-half of all older (≥65 years) patients in the phase 3 AZA-AML-001 trial had newly diagnosed AML-MRC. We compared clinical outcomes for patients with AML-MRC treated with azacitidine or conventional care regimens (CCR; induction chemotherapy, low-dose cytarabine, or supportive care only) overall and within patient subgroups defined by cytogenetic risk (intermediate or poor) and age (65-74 years or ≥75 years). The same analyses were used to compare azacitidine with low-dose cytarabine in patients who had been preselected to low-dose cytarabine before they were randomized to receive azacitidine or CCR (ie, low-dose cytarabine). Median overall survival was significantly prolonged with azacitidine (n = 129) versus CCR (n

Refractory cytopenia of childhood (RCC) is a subgroup of myelodysplastic syndrome (MDS), having been added to the World Health Organization classification in 2008. Before then, RCC cases were classified as childhood aplastic anemia. RCC is the most common form of MDS in children and adolescents, accounting for approximately half of all MDS cases. Symptoms result from underproduction of red blood cells (weakness, pallor, failure to thrive, pica), white blood cells (recurrent or overwhelming infection), and/or platelets (bleeding). Bone marrow transplant is the only known curative treatment. The bone marrow of patients with RCC contains islands of erythroid precursors and spare granulocytes. In some scenarios, multiple bone marrow biopsy examinations may be recommended before a diagnosis can be established. Niemeyer, C. M.; Baumann, I (2011).

The myelodysplastic syndromes (MDS) are a heterogeneous group of clonal hematopoietic stem cell malignancies that are characterized by ineffective hematopoiesis resulting in peripheral cytopenias, and typically a hypercellular bone marrow. The MDS are pre-leukemic conditions showing frequent progression (in approximately 40% of patients) to acute myeloid leukemia (AML). In the early stages of the disease, apoptosis of bone marrow precursor cells prevails, but in more advanced disease increased proliferation of immature blasts occurs.1 About 50% of MDS exhibit acquired genomic abnormalities detected by conventional cytogenetic banding techniques. Recent molecular investigations have revealed additional genetic abnormalities in MDS, including micro-deletions and loss of heterozygosity due to acquired uniparental disomy (UPD).2. Interstitial deletion within the long arm of chromosome 5 [del(5q)] is one of the most frequent cytogenetic abnormalities observed in myeloid malignancies, occurring in ...
Hetty Carraway, MD: Lets talk a little bit about the patients with lower-risk MDS [myelodysplastic syndromes]. What kinds of therapies might be available to a patient, particularly if they present with an isolated anemia or low hemoglobin? What should they be asking you or thinking about?. Guillermo Garcia-Manero, MD: Thank you, Hetty. First of all, I think around 60% of patients with MDS will first present in a lower-risk category. What you do first is look at the bone marrow test, of course, but lets go one by one. The first line of therapy for someone who just has anemia may be a drug that stimulates red blood cell production. We call those agents erythropoiesis-stimulating agents, or ESAs, and there are a couple of them that can be very effective in the correct subset. We measure something in the blood of the patient called the erythropoietin level, and if thats low, the patient will most likely respond to ESAs. Those drugs are biological agents. They are actually a hormone that we have ...

In MDS, the bone marrow isnt able to make enough normal, healthy blood cells that the body needs. 9 Do I have MDS? MDS often causes a low number of one or more types of blood cells. Another key feature is that the defective blood cells have an abnormal size, shape, or look. This is called dysplasia. 12 Blood tests are done along with other initial tests to help diagnose MDS. 16 Your bone marrow must be tested to confirm if you have MDS. 18 How do doctors group MDS for treatment ...

Myelodysplastic syndromes (MDS) describe a heterogeneous and complex group of clonal bone marrow failure disorders characterized by ineffective hematopoiesis, peripheral cytopenias, morphologic dysplasia, and cellular dysfunction, often leading to increased risk of infection and transfusion requirements. They typically represent diseases of the elderly, and, while sometimes linked to known environmental exposures, are usually characterized as idiopathic. Understanding MDS pathogenesis is crucial to the development of biologically targeted therapies. This chapter explores MDS pathogenesis theories in terms of (1) the MDS cell of origin; (2) genetic alterations within the cell of origin; (3) alterations in bone marrow microenvironment and apoptosis; (4) alterations in immune surveillance; and (5) functional cellular abnormalities. ...

Hello everyone, I am new in this forum community, and I have a question on a very rare occasion concerning T-LGL leukemia. My mom was diagnosed with chronic T-LGL some years ago (thank God still in non-critical levels, even though barely), and her spleen is slightly enlarged but not removed. However, even though I heard T-LGL L. makes platelets (thrombocytes) to drop in numbers, my mothers final results showed an immense-abnormal increase! Even when she retook the blood tests after some
Safety and efficacy of azacitidine in myelodysplastic syndromes Carlos E Vigil, Taida Martin-Santos, Guillermo Garcia-ManeroDepartment of Leukemia, The University of Texas MD Anderson Cancer Center, Houston, TX, USAPurpose: The clinical efficacy, different dosages, treatment schedules, and safety of azacitidine are reviewed.Summary: Azacitidine is the first drug FDA-approved for the treatment of myelodysplastic syndromes that has demonstrated improvements in overall survival and delaying time to progression to acute myelogenous leukemia. The recommended dosage of azacitidine is 75 mg/m2 daily for 7 days, with different treatment schedules validated. It appears to be well tolerated, with the most common adverse effects being myelosuppression. Several other off-label recommendations were also analyzed.Conclusion: Azacitidine is the first DNA hypomethylating agent approved by FDA for the treatment of myelodysplastic syndromes with demonstrated efficacy.Keywords: Azacitidine, MDS, hypomethylating agents

Recent studies suggested that immunological and microenvironmental factors play a role in the pathophysiology of this disease. We report a significant increase in apoptosis in bone marrow B lymphocytes in MDS as compared to that found in acute myeloid leukemia and healthy controls. Furthermore, we demonstrate that patients with refractory ...

Changes in RPS14 expression levels during lenalidomide treatment in Low- and Intermediate-1-risk myelodysplastic syndromes with chromosome 5q deletion.
Pgreater thanThis prospective Phase II study is the first to assess the feasibility and efficacy of maintenance 5-azacytidine for older patients with high-risk myelodysplastic syndrome (MDS), chronic myelomonocytic leukaemia and MDS-acute myeloid leukaemia syndromes in complete remission (CR) after induction chemotherapy. Sixty patients were enrolled and treated by standard induction chemotherapy. Patients that reached CR started maintenance therapy with subcutaneous azacytidine, 5/28 d until relapse. Promoter-methylation status of CDKN2B (P15 ink4b), CDH1 and HIC1 was examined pre-induction, in CR and 6, 12 and 24 months post CR. Twenty-four (40%) patients achieved CR after induction chemotherapy and 23 started maintenance treatment with azacytidine. Median CR duration was 13 center dot 5 months, greater than 24 months in 17% of the patients, and 18-30 center dot 5 months in the four patients with trisomy 8. CR duration was not associated with CDKN2B methylation status or karyotype. Median ...
BACKGROUND: Myelodysplastic syndromes are characterised by ineffective erythropoiesis. Luspatercept (ACE-536) is a novel fusion protein that blocks transforming growth factor beta (TGF β) superfamily inhibitors of erythropoiesis, giving rise to a promising new investigative therapy. We aimed to assess the safety and efficacy of luspatercept in patients with anaemia due to lower-risk myelodysplastic syndromes. METHODS: In this phase 2, multicentre, open-label, dose-finding study (PACE-MDS), with long-term extension, eligible patients were aged 18 years or older, had International Prognostic Scoring System-defined low or intermediate 1 risk myelodysplastic syndromes or non-proliferative chronic myelomonocytic leukaemia (white blood cell count ,13 000/μL), and had anaemia with or without red blood cell transfusion support ...
Full Title A Phase I/II Study to Investigate the Safety and Clinical Activity of GSK3326595 and Other Agents in Subjects with Myelodysplastic Syndrome and Acute Myeloid Leukemia Purpose The purpose of this study is to find the highest dose of the investigational drug GSK3326595 that can be given to patients with myelodysplastic syndromes (MDS), chronic myelomonocytic leukemia (CMML), or acute myeloid leukemia (AML). GSK3326595 blocks two proteins that can cause cancer cell growth: PRMT5 and MEP50. By blocking PRMT5 and MEP50, GSK3326595 may slow or stop cancer growth.
MGI Pharma, Inc, and SuperGen, Inc, recently announced that the US Food and Drug Administration (FDA) has approved the hypomethylating agent decitabine (Dacogen) for injection. Decitabine is indicated for treatment of patients with myelodysplastic syndromes (MDS) including previously treated and untreated, de novo, and secondary MDS of all French-American-British (FAB) subtypes (refractory anemia, refractory anemia with ringed sideroblasts, refractory anemia with excess blasts, refractory anemia with excess blasts in transformation, and chronic myelomonocytic leukemia), and intermediate-1, intermediate-2, and high-risk International Prognostic Scoring System (IPSS) groups. 1
Myelodysplastic syndrome (MDS) is characterized by ineffective hematopoiesis and hyperplastic bone marrow. Complete loss or interstitial deletions of the long arm of chromosome 5 occur frequently in MDS. One candidate tumor suppressor on 5q is the mammalian Diaphanous (mDia)-related formin mDia1, encoded by DIAPH1 (5q31.3). mDia-family formins act as effectors for Rho-family small GTP-binding proteins including RhoB, which has also been shown to possess tumor suppressor activity. Mice lacking the Drf1 gene that encodes mDia1 develop age-dependent myelodysplastic features. We crossed mDia1 and RhoB knockout mice to test whether the additional loss of RhoB expression would compound the myelodysplastic phenotype. Drf1−/−RhoB−/− mice are fertile and develop normally. Relative to age-matched Drf1−/−RhoB+/− mice, the age of myelodysplasia onset was earlier in Drf1−/−RhoB−/− animals-including abnormally shaped erythrocytes, splenomegaly, and extramedullary hematopoiesis. In addition, we

People with inherited syndromes such as Fanconi anemia, Diamond Blackfan anemia, familiar platelet disorder, severe congenital neutropenia or Shwachman-Diamond syndrome may also have a higher risk of developing a myelodysplastic syndrome due to the genetic defects that cause these conditions to develop. Additionally, these inherited syndromes are commonly treated with bone marrow transplants, which is often performed with a high-dose course of chemotherapy. This chemotherapy can further increase a persons risk of developing MDS.. Additionally, a history of exposure to environmental and occupational carcinogens such as benzene, chemical fertilizers, nitro-organic explosives and diesel derivatives can also increase a persons risk of developing a myelodysplastic syndrome. Studies have found higher rates of these syndromes among industrial workers such as plant and machine operators and assemblers, as well as in coal miners and agricultural workers. Regardless of a persons occupational history, ...

The tumour cells were positive for lysozyme, peroxidase, CD11a, CD11c, CD33 and HLA-DR, and weakly positive for CD4 and CD14, suggesting granulocytic differentiation. The bone marrow at admission showed dysplasia of the erythrocytic and granulocytic lineage and complex chromosomal abnormalities in association with an increase in monocytes. The patient was diagnosed as having granulocytic sarcoma of monocytic lineage with concomitant myelodysplastic syndrome. In this case, tumour cells also expressed the neural cell adhesion molecule (CD56), which has been suggested as a possible risk factor for ...

Sponsor. Eastern Cooperative Oncology Group through the NCI-sponsored Cancer Cooperative Group Program. Purpose of the Study. To find out whether the addition of PSC-833 to a standard chemotherapy drug combination is beneficial in treating patients with poor-risk acute myelogenous leukemia (AML) that has returned or is resistant to treatment and in patients with high-risk myelodysplastic syndrome (MDS). Laboratory studies have shown that PSC-833 may decrease the resistance of leukemia cells to combination chemotherapy, and enhance the effectiveness of treatment.. Results. The study did not show improved anti-leukemia effects in combination chemotherapy plus PSC-833 compared with combination chemotherapy alone in patients with poor-risk AML or high-risk MDS.. Conclusion. No other studies are ...

Long non-coding RNAs (lncRNAs) are non-protein coding transcripts longer than 200 nucleotides. LncRNAs have been recently recognized as the hallmark features in various diseases. In hematopoiesis, they regulate development at almost every stage of cell lineage differentiation; therefore, abnormal expression of lncRNAs may lead to different hematopoietic disorders. Until now there has been almost no information available about lncRNA deregulation and role in myelodysplastic syndromes (MDS).. We perform genome-wide screening of lncRNA levels in MDS patients and compare expression profiles between various risk groups of patients and healthy subjects, to find lncRNAs with altered levels in MDS. This knowledge will help us to better understand the pathogenesis of MDS and identify lncRNAs that may represent candidate diagnostic and prognostic molecular markers of the disease.. ...

METHODS: A case-referent study was conducted with 330 MDS patients investigated cytogenetically in 1976-1993 (cases) and matched referents. Telephone interviews with either the person or a next-of-kin were used. The participation rate of the cases and referents was 85% and 60%, respectively. Information was obtained from the next-of-kin more often for the cases (88%) than for the referents (26%). Occupational hygienists assessed the exposure using interview data on worktasks and hobbies. Associations with disease risk were evaluated for 10 exposures with a logistic regression analysis. RESULTS: The investigated exposures were generally not associated with cytogenetically abnormal MDS. Effect estimates ...
The pathophysiology of myelodysplasia is complex. There is evidence for impairments in stem cell growth, progenitor maturation, and both growth factor production and progenitor responsiveness. The presence of ineffective hematopoiesis (increased apoptosis of maturing marrow precursors) is a hallmark of myelodysplasia. It appears to correlate in part with CD95 expression and persistent high levels of Fas receptor, resulting in increased fas-ligand apoptosis. Upregulation of the cytokines tumor necrosis factor α (TNF-α) and interleukin 1β (IL-1β) also may play a role in promoting apoptosis of long-term hematopoietic stem cells (LT-HSC) and committed precursors in myelodysplastic marrows. Vascular endothelial growth factor (VEGF) overproduction is thought to be involved in the promotion of myeloblastic elements, and perhaps the evolution to acute myeloid leukemia (AML). ...

We describe severe hypokalaemia and hypertension due to a mineralocorticoid effect in a patient with myelodysplastic syndrome taking posaconazole as antifungal prophylaxis. Two distinct mechanisms due to posaconazole are identified: inhibition of 11β hydroxylase leading to the accumulation of the mineralocorticoid hormone 11-deoxycorticosterone (DOC) and secondly, inhibition of 11β hydroxysteroid dehydrogenase type 2 (11βHSD2), as demonstrated by an elevated serum cortisol-to-cortisone ratio. The effects were ameliorated by spironolactone. We also suggest that posaconazole may cause cortisol insufficiency. Patients taking posaconazole should therefore be monitored for hypokalaemia, hypertension and symptoms of hypocortisolaemia, at the onset of treatment and on a monthly basis. Treatment with mineralocorticoid antagonists (spironolactone or eplerenone), supplementation of glucocorticoids (e.g. hydrocortisone) or dose reduction or cessation of posaconazole should all be considered as ...
