BACKGROUND: Children with acute myeloid leukemia (AML) are at high risk of life-threatening bacterial and fungal infection. However, little is known about the prevalence or severity of adenovirus infection in this population. Objective was to describe the characteristics, treatments and outcomes of adenovirus infection in children with newly diagnosed AML. METHODS: We performed a retrospective chart review based upon two multi-center cohort studies which focused on identifying risk factors for infection in children with AML...

BACKGROUND: It is well established that expression of multi-drug resistance (MDR) proteins (MDR1, BCRP, MDR3, MRP1 and LRP) in leukemic blasts correlates with AML patients clinical response. Assuming that leukemic stem cells (LSC) are resistant to chemotherapy and responsible for relapse it might be clinically relevant to evaluate the expression level of MDR proteins in LSC and relate it to the clinical outcome. METHODS: Bone marrow samples from 26 patients with de novo AML were labeled with antibodies to distinguish CD34+CD38-CD123+ LSC population and with antibodies against MDR1, BCRP, MDR3, MRP1 or LRP proteins...

The treatment of acute myeloid leukemia (AML) in older patients is undergoing rapid changes, with a number of important publications in the past five years. Because of this, a group of Canadian leukemia experts has produced an update to the Canadian Consensus Guidelines that were published in 2013, with several new agents recommended, subject to availability. Recent studies have supported the survival benefit of induction chemotherapy for patients under age 80, except those with major co-morbidities or those with adverse risk cytogenetics who are not candidates for allogeneic hematopoietic stem cell transplantation (HSCT)...

INTRODUCTION: Nilotinib is a highly effective tyrosine kinase inhibitor in the treatment of chronic myeloid leukemia (CML). However, reports of cardiovascular toxicities caused by nilotinib have recently raised critical concerns. The aim of the present study was to evaluate the incidence of cardiovascular events (CVEs) and frequency of asymptomatic peripheral arterial disease (PAD) after long-term exposure to nilotinib. PATIENTS AND METHODS: In the present retrospective cohort, we evaluated the incidence of CVEs in 63 CML patients treated with nilotinib...

Chronic lymphocytic leukemia (CLL) is the most common leukemia in the Western world, characterized by the presence of long-lived circulating leukemic cells in the peripheral blood that may infiltrate all organs, particularly those of the reticulo-endothelial system. Liver enlargement and elevation of liver enzymes related to specific involvement by the underlying disease are well-recognized features in these patients. In CLL, the differential diagnosis of liver disorders is broad and includes liver infiltration by leukemic cells, immunologic manifestations associated with CLL, primary and secondary hepatic malignancies, drug-induced hepatotoxicity, infections, and Richter transformation...

The clinical consequences of the infectious events in patients receiving azacitidine are poorly documented. Likewise, the role of primary antimicrobial prophylaxis is unknown. In this retrospective, single-center study, we compare the impact of prophylaxis on the incidence of infection and morbidity in all consecutive higher-risk myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML) patients, during the first 4 azacitidine cycles. Seventy-six patients, corresponding to 283 azacitidine cycles, were studied...

Acute myelogenous leukemia (AML) is primarily a disease of the elderly, and as such, our approach to treatment needs to be tailored to address an aging population. Allogeneic hematopoietic stem cell transplantation (allo-HSCT) remains the only potentially curative treatment for intermediate and high risk AML, and until recently, its use had been limited to a younger population and dependent on availability of a donor. Advances in conditioning regimens, supportive care, and the use of alternative donor sources have greatly expanded access to this therapy...

Acute myeloid leukemia (AML) is a lethal malignancy because patients who initially respond to chemotherapy eventually relapse with treatment refractory disease. Relapse is caused by leukemia stem cells (LSCs) that reestablish the disease through self-renewal. Self-renewal is the ability of a stem cell to produce copies of itself and give rise to progeny cells. Therefore, therapeutic strategies eradicating LSCs are essential to prevent relapse and achieve long-term remission in AML. AML is a heterogeneous disease both at phenotypic and genotypic levels, and this heterogeneity extends to LSCs...

Leukemic cells can induce defective expression of soluble factors and change marrow cytokine profile, leading to aberrant cell signaling, cell fixation and cell proliferation in bone marrow. T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive disorder which accounts for 15% of pediatric ALL. To evaluate the contribution of immunological factors on T-ALL survival, we measured Th1, Th2, Th17 cytokines and soluble HLA-G (sHLA-G) levels in bone marrow from 32 Brazilian children at diagnosis (D0), after induction (D19) and after consolidation (D49) of the chemotherapy phase...

L-asparaginase has been used in the treatment of patients with acute lymphoblastic leukemia (ALL) for more than 30 years. Rapid clearance of the enzyme from blood stream and its L-glutaminase-dependent neurotoxicity has led to searching for new L-asparaginases with more desirable properties. In the present study, L-asparaginase coding gene of Halomonas elongata was isolated, expressed in Escherichia coli, purified, and characterized. The purified protein was found to have a molecular mass of 39.5 kDa and 1000-folds more activity towards L-asparagine than L-glutamine...

Various eukaryotic translation initiation factors (eIFs) have been implicated in carcinoma development. Eukaryotic translation initiation factor 3 subunit D (eIF3D) has recently been shown to regulate the growth of several types of human cancer cells. However, the function of eIF3D in acute myeloid leukemia (AML) remains unclear. In this study, we investigated the expression of eIF3D in three AML cell lines and a lymphoblast cell line, and found that eIF3D was expressed in all four leukemia cell lines. To explore the role of eIF3D in AML cell proliferation, lentivirus-mediated RNA interference was applied to knock down the expression of eIF3D in U937 cells...

T-cell acute lymphoblastic leukemia (T-ALL) is a genetically heterogeneous disease that can be classified into different molecular genetic subtypes according to their mRNA gene expression profile. In this study, we applied RNA sequencing to investigate the full spectrum of miRNA expression in primary T-ALL patient samples, T-ALL leukemia cell lines and healthy donor thymocytes. Notably, this analysis revealed that genetic subtypes of human T-ALL also display unique miRNA expression signatures, which are largely conserved in human T-ALL cell lines with corresponding genetic background...

Background: Acute myeloblastic leukemia (AML) is a clonal disorder due to bone marrow failure and uncontrolled proliferation of myeloid lineage. Acute promyelocytic leukemia (APL) is a subtype of AML. Heterocyclic compounds, such as indole, are considered as attractive candidates for cancer therapy, due to their abundance in nature and known biological activity. Sal-like protein (SALL4) is a zinc finger transcription factor involving in the multi-potency of stem cells, in the NB4 cell line...

Chemical investigation of a bioactive methanolic extract of the fruiting bodies of Piptoporus betulinus led to the isolation of five previously undescribed lanostane triterpenoids named piptolinic acids A-E, as well as five known lanostane triterpenoids. Their structures were elucidated on the basis of 1D and 2D NMR spectroscopic and HRESIMS analysis. Piptolinic acid A with an unusual moiety (3-hydroxy-4-methoxycarbonyl-3-methylbutyryloxy) at C-3 exhibited comparable cytotoxic activity against human promyelocytic leukemia cell line HL-60 (IC50 = 1...

OBJECTIVE: Persistence of leukemic cells after induction therapy has been shown to correlate with poor survival in acute myeloid leukemia (AML). In this study we tested if human mesenchymal stromal cells (hMSC) have protective effects on leukemic cells undergoing chemotherapy. METHODS: Persistent disease was used as marker to identify cases with therapy resistant leukemic cells in 95 AML patients. Immunophenotyping, cell cycle and apoptosis assays were assessed by flow-cytometry...

Acute myeloid leukemia (AML) remains a therapeutic challenge. Despite ongoing research, the standard therapy for AML has not changed significantly in the past four decades. With the identification of cytogenetic and molecular abnormalities, several promising therapeutic agents are currently being investigated. FLT3 mutation is a well-recognized target seen in 30% of the cytogenetically normal AML. More recently, the BCL2 family of anti-apoptotic proteins have also generated great interest as a therapeutic target...

Acute lymphoblastic leukemia is characterized by unchecked proliferation of malignant lymphoblasts which replaces the normal bone marrow culminating in anemia due to red blood cells inadequacy as well as in easy bruising/bleeding secondary to insufficient platelets production. Even the white blood cells which are produced excessively are immature and abnormal. ALL is the most common hematological malignancy in children. Most commonly, patients present with lymphadenopathy, recurrent infections, bleeding, fatigue, and bone pains...

Improvements in supportive care have enabled allogeneic hematopoietic cell transplant (HCT) to be performed in increasingly older patients. HCT is associated with neurocognitive impairment, which may be exacerbated in older adults due to normal neurocognitive decline associated with aging. The goal of this study was to evaluate whether increased age in allogeneic HCT recipients is associated with worse neurocognitive outcomes over time relative to a matched sample of individuals without cancer. Patients (n = 140; 42% female, M age = 51, range = 20-76; 31% with acute myeloid leukemia) completed neurocognitive assessments before transplant and three months and one year post-transplant...
