Haemostasis and cardiovascular disease

The term 'coronary thrombosis' was derived from clinical and pathological observations on myocardial infarction made at least 80 years ago' and perhaps even earlier.'·} It was probably not until the 1930s that clinically manifest ischaemic heart disease in the form of myocardial infarction became a familiar condition rather than the unusual occurrence or even the rarity it had hitherto been. When the growing epidemic of clinical ischaemic heart disease prompted an increasing and concerted research programme after the Second World War, interest largely centred on the lipid nature of the atheromatous plaque and the contributions dietary fat intake and blood cholesterol levels make to it

Hepatic cyst infection following aspiration sclerotherapy: a case series

Contains fulltext : 138159.pdf (publisher's version ) (Open Access)Mass-related symptoms caused by hepatic cysts are effectively treated by aspiration sclerotherapy (AS). This minimal-invasive intervention is regarded as a safe procedure. Hence, occurrence of complications is low. Transient fever is commonly reported as a side effect. However, documentation on a post-procedural hepatic cyst infection as a complication of AS is limited. We present five cases in which a tentative diagnosis of post-procedural hepatic cyst infection was made. Patients typically presented with abdominal pain and fever, had to be admitted to our hospital, and were treated with long term antibiotics. Ultimately, the cyst infection successfully resolved with ciprofloxacin in all cases

Study protocol and pilot results of an observational cohort study evaluating effect of red blood cell transfusion on oxygenation and mitochondrial oxygen tension in critically ill patients with anaemia: the INsufficient Oxygenation in the Intensive Care Unit (INOX ICU-2) study

INTRODUCTION: The recently developed protoporphyrin IX-triple state lifetime technique measures mitochondrial oxygenation tension (mitoPO2) in vivo at the bedside. MitoPO2might be an early indicator of oxygen disbalance in cells of critically ill patients and therefore m

Product type and the risk of inhibitor development in nonsevere haemophilia A patients: a case‒control study

Inhibitor development is a major complication of treatment with factor VIII concentrates in nonsevere haemophilia A. It has been suggested that plasma-derived factor VIII (FVIII) concentrates elicit fewer inhibitors than recombinant FVIII concentrates, but studies in severe haemophilia A patients have shown conflicting results. We designed a case‒control study to investigate the clinical and genetic risk factors for inhibitor development in nonsevere haemophilia A patients. We investigated whether the type of FVIII concentrate was associated with inhibitor development in nonsevere haemophilia A patients. This nested case‒control study includes 75 inhibitor patients and 223 controls, from a source population of the INSIGHT study, including all nonsevere haemophilia A patients (FVIII:C 2–40%) that were treated with FVIII concentrates in 33 European and one Australian centre. Cases and controls were matched for date of birth and cumulative number of exposure days (CED) to FVIII concentrate. A conditional logistic regression model was used to calculate unadjusted and adjusted odds ratios. No increased risk for inhibitor development was found for any type of FVIII concentrate; either when comparing recombinant FVIII concentrates to plasma-derived FVIII concentrates (adjusted odds ratio 0·96, 95% confidence interval (CI) 0·36–2·52) or for specific types of FVIII concentrates

Desmopressin in moderate hemophilia a patients: A treatment worth considering

Desmopressin increases endogenous factor VIII levels in hemophilia A. Large inter-individual variation in the response to desmopressin is observed. Patients with a lower baseline factor VIII activity tend to show a reduced response, therefore, desmopressin is less frequently used in moderate hemophilia A patients (baseline factor VIII activity 1-5 international units/deciliter), even though factor VIII levels may rise substantially in some of them. We aim to describe the response to desmopressin in moderate hemophilia A patients and to identify predictors. We selected data on 169 patients with moderate hemophilia from the multicenter Response to DDAVP In non-severe hemophilia A patients: in Search for dEterminants (RISE) cohort study. Adequate response to desmopressin was defined as a peak factor VIII level ≥ 30, and excellent response as ≥ 50 international units/deciliter after desmopressin administration. We used univariate and multiple linear regression techniques to analyze predictors of the peak factor VIII level. Response was considered adequate in 68 patients (40%), of whom 25 showed excellent response (15%). Intravenous administration, age, pre-desmopressin factor VIII activity and von Willebrand factor antigen, peak von Willebrand factor activity and desmopressin-induced rise in von Willebrand factor antigen were significant predictors of peak factor VIII level and explained 65% of the inter-individual variation. In 40% of moderate hemophilia A patients, desmopressin response was adequate, thus it is important not to withhold this group of patients from desmopressin responsiveness. Among the six predictors that we identified for desmopressin-induced factor VIII rise, factor VIII activity and desmopressin-induced rise in von Willebrand factor antigen had the strongest effect
