Goldbloom syndrome is a rare clinical entity, of unknown etiology that happens almost exclusively in pediatric population. It is a prolonged febrile syndrome with periosteal hyperostosis and dysproteinemia, and often simulates an hematooncology or lymphoproliferative disease. The diagnosis is to rule out the different causes of bone pain associated with hypergammaglobulinemia, hypoalbuminemia, high erythrocyte sedimentation rate and periostitis at the radiographies. Symptomatology, radiology and laboratory parameters refer in a variable time, usually from 3 to 12 months...

The use of therapeutic plasma exchange in the pediatric age group is mostly based on retrospective, single-center experiences. The decision to implement apheresis in pediatric patients is usually adopted from the results of studies on adult patients. In order to expand the limited data on pediatric TPE in general and non-hematooncological disorders in particular, we retrospectively evaluated TPE experience in pediatric patients who underwent the procedure for reasons other than hematooncological disorders. A total of 160 sessions in 34 patients (21 females and 13 males) with a median age of 7 (1-17) were analyzed...

BACKGROUND: Storage time of platelet (PLT) concentrates has been negatively associated with clinical efficacy outcomes. The aim of this study was to quantify the association between storage time of PLT concentrates and interval to the next PLT transfusion for different types of PLT components, stored for up to 7 days and transfused to transfusion-dependent hematooncology patients with thrombocytopenia. STUDY DESIGN AND METHODS: From a cohort of patients from 10 major Dutch hospitals, patients were selected whose transfusion patterns were compatible with PLT transfusion dependency due to hematooncologic disease...

BACKGROUND: Archiving of biological materials in biobanks is considered to be the initial crucial part of research activities. Most often, biobanks are founded for research purposes since they allow collection of sufficient material for analysis of new or testing of previously identified biomarkers. Biobanking needs to quickly react to current needs of researchers as well as clinicians, it is not a rigid system. Laboratory analyses of monoclonal gammopathies are based on separation of plasma cells from bone marrow of patients...

BACKGROUND: Primary human B cells chronic lymphocytic leukemia undergoes apoptosis, from which they can be rescued by contact with stromal cells or by the addition of specific soluble factor, when cultured in vitro. For research purposes of the behavior of CLL cells we created 3D in vitro model in which we simulated appropriate microenvironment for CLL cells to allow study the mechanism of survival of these cells in long-term cultivation. MATERIAL AND METHODS: Our aim was the scaffold structure to be geometrically similar to the 3D morphology of supporting bone marrow tissue in a trabecular bone; the 3D scaffold was also designed to conform to biocompatibility, sufficiently large surface area for cell attachment, high porosity for cell migration, proliferation and transport of nutrients...

BACKGROUND: Hematopoietic stem cell transplantation (HSCT) remains the most efficacious therapy in patients with acute leukemia. For older patients and those lacking a related HLA-compatible donor, autologous transplantation (auto-HSCT) is a valid alternative therapeutic option. METHODS: From 1997 until 2014 in the Department of Hematooncology and Bone Marrow Transplantation, Medical University of Lublin, Poland, 29 auto-HSCT were performed in patients with acute myeloid leukemia (AML; 15 men and 14 women; median age, 52...

UNLABELLED: Rituximab, a monoclonal antibody against the surface antigen of B-lymphocytes CD20 is beeing used in the treatment of numerous hematological, hematooncological and autoimmune disorders. After administration of ritu-ximab, quick and almost complete depletion of B-lymphocytes with the exception of pre-B-lymphocytes and plasma cells occur. Neutropenia and low serum antibody levels in classes IgA, IgM and IgG may also develop. These changes usually persist for 6-12 months, rarely for several years...

The experimental platform in hematooncology is still searching for more valid prognostic and predictive factors on clinical, morphological and molecular levels. The bridge closer to daily practice is so-called translation medicine and from this point of view we have tried to sort diffuse large B-cell lymphoma not otherwise specified. The applied methodological approaches are morphology, indirect immunohistochemistry on formaline-fixed, parrafin-embeded tissue, Hans classifier sorting, expression of Bcl-2, CD5, CD20, CD30 and NfκB proteins in comparison with the clinical (Ann Arbor stage, IPI, aa-IPI, PFS, OS), laboratory and cytogenetic results (complex and simplex karyotypes)...

Monoclonal B-cell lymphocytosis (MBL) and monoclonal gammopathy of undetermined significance (MGUS) result from clonal expansions of mature B or plasma cells. Here, we set out to determine the immunophenotypic/monoclonal immunoglobulin (M protein) features and co-prevalence of MBL and MGUS in a hospital-based cohort of 1909 non-hematooncological patients. Of the evaluable cases, 3.8 % showed evidence for MBL by immunophenotyping, while 9.8 % were screened positive for M protein by immunofixation. With six concomitant cases (0...

The development of various analitic techniques like classical cytogenetics, molecular cytogenetics and molecular methods has greatly improved our ability to understand the basis of cancer development, that can be helpful in hematological diagnostics and treatment. Thus, improving these methods and raising the diagnostic standards remain of key importance in haematooncology. The influence of cytogenetic and biomolecular analysies on clinical decisions has increased considerably recently, but laboratory techniques have to be optimized to provide reliable results for the best patient care...

BACKGROUND AND OBJECTIVES: Different methods of platelet concentrate preparations leave behind certain number of residual leukocytes, accounting for most of the febrile nonhemolytic transfusion reactions, especially in multitransfused patients. Various inflammatory cytokines, such as tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and IL-6 are generated during storage and have been implicated for these adverse effects. We have studied the levels of these cytokines and their correlation with leucocyte contents in platelet concentrates prepared by three different methods...

BACKGROUND: Minimal residual disease (MRD) detection is an essential tool for therapy response assessment in a considerable number of hematooncologic disorders, including mantle cell lymphoma (MCL). Flow cytometry (FCM) ranks among the most effective approaches, which allows rapid sample processing and compete successfully with highly sensitive molecular methods like polymerase chain reaction. Because FCM is ordinarily applied to detect MRD in B-lineage diseases like chronic lymphocytic leukemia, a similar method could be used in MCL...
