C1-esterase inhibitor (C1-Inh) therapy was introduced in clinical medicine about 25 years ago as a replacement therapy for patients with hereditary angioedema caused by a deficiency of C1-Inh. There is now accumulating evidence, obtained from studies in animals and observations in patients, that administration of C1-Inh may have a beneficial effect as well(More)
OBJECTIVE In sepsis, activation of coagulation and inhibition of fibrinolysis lead to microvascular thrombosis. Thus, clot stability might be a critical issue in the development of multiple organ dysfunction syndrome. Activated FXIII (FXIIIa) forms stable fibrin clots by covalently cross-linking fibrin monomers. Therefore, we investigated the impact of(More)
In a previous study, the authors found persistent presence of acute inflammation markers such as C-reactive protein and complement factors locally in burn wounds. This persistence of acute inflammation may not only delay local burn wound healing but also have a systemic effect, for instance on the heart. Here, the effects of C1 esterase inhibitor (C1inh),(More)
Hepatocellular carcinoma (HCC) is a well-known consequence of hepatitis C virus (HCV) infection mainly in cirrhotic patients. Associations of other malignancies such as cholangiocellular carcinoma and B-cell malignancies with HCV are less well known. Here we review pathophysiological aspects of malignancies associated with HCV infection. A case report of(More)
Low-molecular weight dextran sulfate (DXS 5000, M(r) 5 kDa) was found to control selectively complement activation without affecting contact activation. However, DXS 5000 being a glycosaminoglycan (GAG) may inhibit coagulation, which might bear the risk of bleeding complications and limit its clinical use. We investigated the influence of DXS 5000 on the(More)
BACKGROUND Insufficient control of von Willebrand factor (VWF) multimer size as a result of severely deficient ADAMTS-13 activity results in thrombotic thrombocytopenic purpura associated with microvascluar thrombosis and platelet consumption, features not seldom seen in severe sepsis and septic shock. METHODS ADAMTS-13 activity and VWF parameters of 40(More)
OBJECTIVE To discuss a possible role of the endothelium in sepsis. DATA SOURCES Studies published in biomedical journals and our own experimental results. STUDY SELECTION Studies on endothelial mechanisms in the context of sepsis. DATA EXTRACTION AND SYNTHESIS Changes in endothelial cells on activation by inflammatory stimuli are reviewed briefly;(More)
OBJECTIVE Multiple organ dysfunction syndrome is a frequent complication of severe sepsis and septic shock and has a high mortality. We hypothesized that extensive apoptosis of cells might constitute the cellular basis for this complication. DESIGN Retrospective study. SETTING Medical and surgical wards or intensive care units of two university(More)
Disseminated intravascular coagulation is a frequent complication of sepsis. Coagulation activation, inhibition of fibrinolysis, and consumption of coagulation inhibitors lead to a procoagulant state resulting in inadequate fibrin removal and fibrin deposition in the microvasculature. As a consequence, microvascular thrombosis contributes to promotion of(More)
C1-inhibitor (C1-inh) is a crucial regulator of the activation of plasmatic cascade systems involved in inflammation contributing to the homeostasis in the generation of proinflammatory mediators. The importance of C1-inh is illustrated by patients with hereditary angioedema where decreased levels of C1-inh lead to an uncontrolled generation of vasoactive(More)
