Deficiencies of antithrombin, protein C, and protein S are associated with an increased risk of venous thromboembolism. The objective of this study was to prospectively assess the incidence of venous thromboembolism in nontreated asymptomatic subjects with such a deficiency. We conducted a prospective cohort study in asymptomatic family members of(More)
In this study, we evaluated the suitability of the calcein assay as a routine clinical laboratory method for the identification of multidrug-resistant phenotype in acute leukaemia. This study presents the results of the calcein tests obtained in two large haematological centres in Hungary. Assays were performed with blast cells of 93 de novo acute leukaemia(More)
The role of reduced endothelial production of EDRF-NO in the pathogenesis of diabetic angiopathy has received much attention, however, most of the rather conflicting data were gained from animal experiments. Limited human experience seems to be available in insulin dependent diabetes, calling attention to decreased EDRF-NO production. Hereby the clinical,(More)
Intravascular EDRF-NO production is known to be impaired in some diseases, e.g., diabetes. This phenomenon may also contribute to the development of diabetic vascular disease. More recently the presence of NO synthase (ecNOS, iNOS) have been recognized in human platelets. Platelets produce NO only during activation, even though in minute amounts. This(More)
Limited information seems to be available about the role of reduced endothelial production of endotheliumderived relaxing factor (EDRF)-nitrate/nitrite (NO) in the pathogenesis of diabetic angiopathy in insulindependent diabetes. A report of urinary and serum nitrate/nitrite, glucometabolic parameters, endothelial and in vivo platelet activation markers of(More)
BACKGROUND A new flow cytometric (FC) BCR-ABL immunobead assay has been developed recently. Here we present the laboratory evaluation of the commercially available kit. METHODS Mononuclear cells were isolated, lysed and processed according to the instructions of the manufacturer. Anti-BCR antibodies adsorbed to capture beads bind the BCR-ABL fusion(More)
Expression of the gene Wilms tumor 1 (WT1) has been suggested as a marker of minimal residual disease in acute myeloid leukemia (AML), but literature data are not without controversy. Our aim was to assess the presence, magnitude and temporal changes of WT1 expression as prognostic factors. 60 AML patients were followed until death or the end of the 6-year(More)
The present study describes severe multiplex cerebral ischaemic laesions in a male patient being diagnosed with polycythaemia vera (PV). In contrast to previous publications, unique platelet receptor pattern with normal platelet count was identified. Glycoprotein Ib receptor number on the surface of resting platelets was increased two-fold and almost(More)
Individual survival probability estimation provided by mathematical models based on cases with a known clinical course is of great help as concerns the treatment strategy decision relating to malignant tumours. Data on four hundred Hungarian papillary thyroid cancer patients were used together with the Markov method to construct a survival model (Orv.(More)
