OBJECTIVES: Multiple myeloma (MM) patients report high symptom burden and reduced health-related quality of life (HRQoL) compared to patients with other haematological malignancies. The aim of this review was to analyze published longitudinal studies including MM patients according to a change in HRQoL scores, which is perceived as beneficial to the patient according to two published guidelines. METHODS: A literature search was performed May 2016. Publications with longitudinal follow-up using the EORTC QLQ-C30 instrument for HRQoL measurement of physical functioning, global quality of life, fatigue and/or pain were included...

Myelodysplastic syndromes (MDS) are oligo-clonal diseases of the hematopoietic stem cell compartment resulting in peripheral cytopenias and a tendency of developing acute myeloid leukemia (AML). MDS show an incidence of approximately 4/100.000/year. However, MDS are mainly a disease of the elderly with a sharp increase in incidence in the age decade above 70 years. Due to the demographic change in western countries, it is expected that the MDS will play an increasing role for these health systems. Although anemia is the predominant cytopenia in the majority of patients, about 30-50% of patients suffer from neutropenia of varying severity...

OBJECTIVES: The phenotypic and functional properties of Tim-3+/PD-1+/CD8+ cells as exhausted T-cells were investigated in chronic lymphocytic leukemia (CLL). METHODS: Frequency of CD8+/Tim-3+/PD-1+ exhausted cells was determined by flow cytometry. For functional analysis, magnetic beads isolated CD8+ T-cells were stimulated with PHA and PMA/ionocymin to assess their proliferative responses and cytokine production by MTT and ELISA, respectively. Cytotoxic activity of isolated CD8+ T-cells was determined using CD107a degranulation assay...

AIMS: Platelets retain cytoplasmic messenger RNA and are capable of protein biosynthesis. Several diseases are known to impact the platelet transcriptome but the effect of non-valvular atrial fibrillation (NVAF) on platelet RNA transcript is essentially unknown. The aim of this study was to evaluate the impact of NVAF on platelet RNA transcript by measuring platelet genes expression in consecutive NVAF patients before and 3-4 months after pulmonary vein isolation (PVI) and compared to normal sinus rhythm controls (NSR)...

OBJECTIVE: Here we present a 7 year old patient suffering from severe haemolytic anaemia. The most common cause of chronic hereditary non-spherocytic haemolytic anaemia is red blood cell pyruvate kinase (PK-R) deficiency. Since red blood cells rely solely on glycolysis to generate ATP, PK-R deficiency can severely impact energy supply and cause reduction of red blood cell lifespan. We determined the underlying cause of the anaemia and investigated why erythroid precursors in the patient survive...

OBJECTIVE: Modified, bio-reactive red blood cells (RBCs) and RBC-derived microvesicles likely contribute to the hematological and cardiovascular complications in end-stage renal disease (ESRD). This study assesses the physiological profile of red blood cells (RBCs) in end-stage renal disease (ESRD) patients receiving standard or high doses of recombinant human erythropoietin (rhEPO). METHOD: Blood samples from twenty-eight patients under sustained hemodialysis, responsive or not to standard rhEPO administration were examined for RBC morphology, fragility, hemolysis, redox status, removal signaling, membrane protein composition and microvesiculation before and after dialysis...

OBJECTIVES: Inherited chromosomally integrated human herpesvirus 6 (ciHHV-6) is characterized by the complete HHV-6 genome integration into the host germ line genome and is vertically transmitted with a Mendelian inheritance. By now, the only relationship between ciHHV-6 and diseases seems to be with angina pectoris. METHODS: We report a case of an 82 years old male diagnosed with Diffuse Large B-cell Lymphoma (DLBCL) on October 2014. To substantiate the suspicion of ciHHV-6, we analysed peripheral blood mononuclear cells, bone marrow biopsy and pleural effusion derived mesothelial cells with PCR, RT-PCR and FISH...

OBJECTIVE: Clinical trials for multiple myeloma patients using novel agent-based regimens before autologous stem cell transplantation (SCT) have shown improvement in response rates and progression-free survival (PFS), however they have failed to identify a significant overall survival (OS) benefit. The aim of this study was to analyze the potential impact of initial induction on the feasibility and outcome of subsequent treatment lines in a real clinical practice setting. METHODS: Consecutive multiple myeloma patients less than 70 years of age diagnosed between 1999 and 2009 were prospectively registered and classified as having received conventional chemotherapy induction regimens with new agents available at relapse (CC cohort, 89 patients) or as treated with novel agents upfront (NA cohort, 65 patients)...

Multiple myeloma (MM) is a hematological malignancy that remains incurable, with relapse rates greater than 90%. The main limiting factor for the effective use of chemotherapies in MM is the serious side effects caused by these drugs. The emphasis in cancer treatment has shifted from cytotoxic, non-specific chemotherapies to molecularly targeted and rationally designed therapies showing greater efficacy and fewer side effects. Traditional chemotherapy has shown several disadvantages such as lack of targeting capabilities, systemic toxicity and side effects; low therapeutic index, as well as, most anticancer drugs have poor water solubility...

OBJECTIVES: We performed a systematic review and meta-regression analysis of randomized control trials to investigate the association between response to initial treatment and survival outcomes in patients with newly diagnosed multiple myeloma (MM). METHODS: Response outcomes included complete response (CR) and the combined outcome of CR or very good partial response (VGPR), while survival outcomes were overall survival (OS) and progression-free survival (PFS). We used random-effect meta-regression models and conducted sensitivity analyses based on definition of CR and study quality...

OBJECTIVES: Here we tested the hypothesis that human M-CSF (hM-CSF) overexpressed in CB CD34(+) cells would induce differentiation and survival of monocytes and osteoclasts in vitro and in vivo. METHODS: Human M-CSF was overexpressed in cord blood CD34(+)  cells using a lentiviral vector. RESULTS: We show that LV-hM-CSF-transduced CB CD34(+) cells expand 3.6 and 8.5 fold more with one or two exposures to the hM-CSF expressing vector, respectively, when compared to control cells...

BACKGROUND: Osteoblasts possess strong growth modulatory activity on hematopoietic stem cells and progenitors. We sought to characterise the growth and differentiation modulatory activities of human osteoblasts at distinct stages of maturation on cord blood (CB) progenitors in the context of osteoblast conditioned medium (OCM). METHODS: OCM was produced from MSC-derived osteoblasts (M-OST) at distinct stages of maturation. The growth modulatory activities of the OCM were tested on CB CD34(+) cells using different functional assays...

OBJECTIVE: α-Thalassemia, one of the most common genetic diseases, is caused by deletions or point mutations affecting one to four α-globin genes. Molecular diagnosis is important to prevent the most severe forms of the disease. However, the diagnosis of α-thalassemia is complex due to a high variability of the genetic defects involved, with over 250 described mutations. We summarize herein the findings of genetic analyses of DNA samples referred to our laboratory for the molecular diagnosis of α-thalassemia, along with a detailed clinical description...

OBJECTIVES: The development of novel agents and an ageing population has led to an increasing number of patients with follicular lymphoma (FL) living longer with disease. Health-related quality of life (HRQOL) is a priority for patients and should guide clinical decisions. The Myeloma Patient Outcome Scale (MyPOS), originally developed for myeloma, was validated in a cross-sectional survey recruiting 124 FL patients. METHODS: Content and construct validity, structural validity using confirmatory factor analyses, reliability and acceptability were evaluated...

To ascertain the incidence/clinical implications of isolated autosomal trisomies in adult acute myeloid leukemia (AML), all such cases were retrieved from the Swedish AML Registry RESULTS: Of the 3,179 cytogenetically informative AMLs diagnosed January 1997 - May 2015, 246 (7.7%) had isolated trisomies. The frequency increased by age (2.4% at age 18-60 years vs. 23% at >60 years; P < 0.0001); the median age was 69 years. The five most common were +8 (4.0%), +13 (0.9%), +11 (0.8%), +21 (0.7%), and +4 (0...
