BACKGROUND Rivaroxaban (Xarelto) does not require routine coagulation monitoring; however, in certain clinical situations (overdose, drug accumulation, urgent surgery) measurement of its plasma concentration is highly recommended. Currently, there is no single hemostasis test that shows a direct correlation between rivaroxaban plasma levels and(More)
In the last decade, peripheral blood was the main source of hematopoietic stem cells (HSC) for autologous and allogeneic transplantation. The exact mechanisms of HSC mobilization are still not clear and the efficacy of the procedure is hardly predictable. Ligand-receptor interactions of adhesion molecules, such as SDF1/CXCR4, VLA4/VCAM-1, or(More)
INTRODUCTION Patients with multiple myeloma (MM) have an increased risk of thromboembolic events (TEE). Due to the complex nature of the prothrombotic state in MM, no single laboratory test has been designed to identify patients with the highest risk of developing TEE. Hence, this study is intended to assess the feasibility of using global hemostasis test(More)
Thromboembolic events (TEE) are a serious clinical problem in multiple myeloma (MM) patients receiving thalidomide (T). Thirty-one MM patients were tested on diagnosis and after 2 and 4 weeks of therapy with T alone, or T in combination with dexamethasone (TD). Closure time (CT) in PFA-100 and P-selectin expression were assessed, as well as plasma levels of(More)
The bone marrow niche functions are modulated by complicated cytokines network. The aim of our study was to evaluate the levels of VCAM-1, VEGF, MMP-9 and SDF during mobilization of CD34+ cells in patients with hematological malignancies. Thirty four patients were enrolled to the study (19F, 15 M) at median age of 57 years. The group consisted of patients(More)
Studies on the adenosine deaminase (ADA) and aldolase activities in lymphocytes were performed in 67 patients with glomerulonephritis (gn) and in 20 healthy individuals from the control group to get an insight into the lymphocyte metabolism. Statistically significant decrease of ADA activity was found in the groups of patients with chronic proliferative gn,(More)
BACKGROUND Congenital fibrinogen disorders (CFD) are rare fibrinogen deficiencies which may be quantitative or functional. The clinical course of hypofibrinogenemia (hypoFI) or dysfibrinogenemia (dysFI) is unpredictable and cannot be determined by the application of standard hemostasis tests. OBJECTIVES The main aim of this study was to assess ROTEM(More)
Patients with multiple myeloma (MM) are at increased risk of thrombosis. Growing evidence indicates that oxidative and nitrative modifications of proteins, including fibrinogen, may lead to changes in hemostasis. The study compares samples from patients with MM at diagnosis and healthy volunteers with regard to the oxidative/nitrative modifications of(More)
Patients with essential thrombocythemia suffer from thrombotic complications that are the main source of mortality. Due to its complex pathogenesis, no existing single laboratory method is able to identify the patients at highest risk for developing thrombosis. Twenty patients with essential thrombocythemia at diagnosis, 15 healthy volunteers and 20(More)
The aim of this work was to determine the activity of helix-destabilizing protein (HD-protein), which is indispensable in basic genetic processes such as DNA replication, genetic recombination and transcription, in lymphocytes of patients with different morphological types of glomerulonephritis and with chronic renal insufficiency, treated conservatively(More)
