Aim of the proposed study will be to investigate whether microvascular blood flow at baseline is impaired in Eisenmenger patients who experience symptoms of the *hyperviscosity syndrome*. Furthermore, in view of the controversy whether to perform…
To determine the rate of transmission of prilocaine across the placentaTo determine the levels of methemoglobinemia in newborns after perineal block with prilocaine during labor (following the regimen used in our hospital)To determine the levels of…
Aim of the study is to investigate the correlation of levels of cleaved protein S and protein S activity with platelet count and levels of markers for platelet destruction
To study the role of GPI-deficiency in susceptibility of hematopoietic stem cells to cytotoxic T lymphocyte (CTL) and Natural Killer (NK) cell mediated lysis in the pathogenesis of PNH.
Aim of the study is to answer the following questions:1. Is cerebral autoregulation impaired in SCD compared to historical control groups and published standard values?2. Do patients with a high level of steady state haemolysis have a more impaired…
In our laboratory we are able to characterize and culture MSCs. In order to study more extensively the possible alterations in MSC biology in AA we will investigate bone marrow cells of patients with newly diagnosed AA and at the time of response…
Primary objective: To evaluate the effect of intravenous vitamin K therapy on the vitamin K dependent coagulopathy in patients with peroxisomal biogenesis disorders measured with APTT, PT, FV, FVII, fibrinogen, d-dimer, thrombocytes and PIVKA.…
Determination of the coefficient of variation of platelet aggregation test with Multiplate. Determining the reliability of the test results after direct assay, when compared to the conventrional (recommended) 30 minutes waiting time.
The primary objective is to determine whether APC is elevated in thrombophilia carriers compared to non-carriers. In parallel we will address. Secondary objectives include assessing whether biomarkers related to angiogenic pathways downstream of APC…
Main: Investigate the cyclic variation in clot lysis time in women with HMB in comparison to controls. Secondary:- Investigate the cyclic variation in TAFI, PAI-1, tPA, PI, thrombin generation, fibrinogen, fibrin clot permeability and confocal…
• The primary objective of this study is to establish the efficacy of fostamatinib as compared with placebo in achieving a stable platelet response in subjects with persistent/chronic ITP.• Secondary objectives include assessment of the incidence of…
Primary outcome parameter is the amount of intra- and postoperative transfusions required. Secondary outcome parameters include intra- and postoperative blood loss, operation time, and postoperative complications and the outcome of…
In this study the cumulative incidence and the clinical and immunogenetic determinants of allo-antibody formation in SCD patients in response to RBC transfusion will be evaluated.
We plan to compare the costs and effects of both methods.
