2. 1. Infectious and bleeding complications in patients with hematological malignancies : Studies on diagnosis and prevention

   Author : Tobias Svensson; Honar Cherif; Martin Höglund; Jan Sjölin; Christine Wennerås; Uppsala universitet; []
   Keywords : Chronic lymphocytic leukemia; Immunodeficiency; Hypogammaglobulinemia; IgG subclass; Pneumococci; Pneumococcal vaccine; Polysaccharide vaccine; Protein-conjugate vaccine; Aspergillosis; Bronchoalveolar lavage; Invasive fungal disease; Pneumocystis jirovecii pneumonia; Myelodysplastic syndrome; Azacitidine; Eltrombopag; Thrombocytopenia; Thrombopoietin receptor; Oncology; Onkologi;

   Abstract : The overall aim of this thesis is to improve knowledge about the prevention of infectious and bleeding complications in patients with hematological malignancies, primarily in those with chronic lymphocytic leukemia (CLL) and myelodysplatic syndrome (MDS).Hypogammaglobulinemia, impaired production of immunoglobulins (Ig), is an established risk factor for infection, but the impact of IgG pure subclass deficiency (IgG subclass deficiency with adequate production of IgG, IgA, and IgM) has been debated.

4. 2. Identification and Characterization of Stem Cells in Preleukemia and Leukemia

   Author : Lars Nilsson; Stamcellscentrum (SCC); []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Haematology; extracellulära vätskor; Hematologi; Philadelphia chromosome; acute lymphoblastic leukemia; polycytemia vera; 5q- syndrome; myelodysplastic syndromes; self-renewal; preleukemia; Hematopoietic stem cells; leukemic stem cells; extracellular fluids;

   Abstract : Hematopoietic stem cells (HSCs) are responsible for the daily and life long production of large numbers of mature blood cells through highly regulated self-renewal and multilineage capabilities. Leukemias on the other hand, are characterized by a clonal, dysregulated, lineage skewed proliferation and impaired differentiation as the result of multiple accumulated genetic events. READ MORE

5. 3. Identification of intrinsic regulators in normal and malignant human hematopoiesis. An RNA-interference approach

   Author : Roman Galeev; Avdelningen för molekylärmedicin och genterapi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hematopoietic stem cell; RNA interference; Acute myeloid leukemia; myelodysplastic syndrome; genetic screens; next generation sequencing; genetic regulators;

   Abstract : Bildandet av blodceller, hematopoesen, utgår från ett litet antal av de så kallade hematopoetiska stamceller som sitter i vår benmärg. Dessa celler har förmågan att ge upphov till alla mogna blodcellstyper av de tre hematopoetiska linjerna, samtidigt som de genom celldelning bibehåller sin egna mängd. READ MORE

6. 4. Studies of anemia in the myelodysplastic syndromes

   Author : Martin Jädersten; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Myelodysplasia; growth factors; Cox regression; delayed entry; left truncation; mortality; international prognostic scoring system; IPSS; who-classification based prognostic scoring system; WPSS; thalidomide analogue; IMiD; hematopoietic stem cell; adhesion; stroma; matrix; osteonectin; matricellular protein; NPM1; immunohistochemistry.;

   Abstract : Background: The myelodysplastic syndromes (MDS) constitute a heterogeneous group of malignant bone marrow disorders, characterized by chronic anemia and increased risk of transformation to acute myeloid leukemia (AML). The first line therapy of anemia in MDS is erythropoietin (EPO) with or without granulocyte colony-stimulating factor (G-CSF). READ MORE

7. 5. TP53 mutations in myelodysplastic syndromes with deletion of 5q

   Author : Leonie Saft; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : The myelodysplastic syndromes (MDS) constitute a heterogeneous group of malignant bone marrow disorders characterized by peripheral cytopenia(s) and increased risk of progression to acute myeloid leukemia (AML). International Prognostic Scoring system (IPSS) Low- or Intermediate (INT)-1 risk MDS with a deletion of 5q (del5q) were considered to have an indolent course and a low risk for progression to AML as compared to other MDS subtypes.
