Severe sepsis still carries a high mortality rate despite advantages in intensive care medicine and antimicrobial therapy. The inflammatory and procoagulant host response to infection are intricately linked and interactions between platelets, leukocytes and the endothelium play a central role in the pathogenesis of septic shock and disseminated intravascular coagulation (DIC). Interestingly, one key player cell in coagulation, i.e. the platelet, has been somewhat neglected as to its position in the pathogenesis of coagulation abnormalities in sepsis. However, thienopyridines, irreversible platelet P2Y12 ADP-receptor antagonists, e.g. prasugrel, could potentially provide beneficial anticoagulatory and antiinflammatory effects: P2Y12 ADP-receptor antagonists reduce TF-induced coagulation activation in various ex vivo and in vitro models. Moreover, various lines of evidence indicate that thienopyridines may block platelet leukocyte interactions and thereby reduce the propagation of the coagulation and inflammation process.
LPS-infusion in healthy volunteers provides a standardized model to safely study non overt DIC and to document possible effects of therapeutic and prophylactic interventions.
The investigators hypothesize that thienopyridines, irreversible platelet P2Y12 ADP-receptor antagonists, may blunt TF-triggered coagulation activation in humans, which will be studied in a TF-dependent coagulation model in humans.

HIV patients are at particular risk to develop cardiovascular disease (CVD) as they exhibit multiple known risk factors for CVD. Of specific concern is the fact that use of the non nucleos...
The primary objective of this study is to assess the pharmacodynamic (PD) effects of clopidogrel and prasugrel when administered after a single subcutaneous (s.c.) dose of ACT-246475 in he...
HIV patients are at particular risk to develop cardiovascular disease (CVD) as they exhibit multiple risk factors by the nature of their pathology. In addition, the long term exposition to...
This study will compare the effect of a prasugrel 10-mg maintenance dose with a clopidogrel 75-mg maintenance dose on platelet activity, approximately 1 week after the first dose of study ...
This study has been designed as a randomized, double-blind trial to provide definitive evidence on the effects of ticagrelor and prasugrel on myocardial salvage in patients with anterior S...
In a double-blinded, randomized, cross-over trial, we investigated hemodynamic effects of high-dose intravenous lipid emulsion (ILE) with/without metoprolol. Ten healthy volunteers each completed four...
The placebo effect is considered the core example of mind-body interactions. However, individual differences produce large placebo response variability in both healthy volunteers and patients. The pla...
The pharmacokinetics (PK) of β-lactam antibiotics in cystic fibrosis (CF) patients has been compared with that in healthy volunteers for over four decades; however, no quantitative models exist that ...
We aimed to investigate the genetic polymorphisms and pharmacogenetic variability associated with the pharmacodynamics (PD) and pharmacokinetics (PK) of prasugrel, in healthy Han Chinese subjects.

Persons with no known significant health problems who are recruited to participate in research to test a new drug, device, or intervention as controls for a patient group. (from http://clinicalcenter.nih.gov/recruit/volunteers.html, accessed 2/14/2013)
Hospital or other institutional ethics committees established to consider the ethical dimensions of patient care. Distinguish from ETHICS COMMITTEES, RESEARCH, which are established to monitor the welfare of patients or healthy volunteers participating in research studies.
Human experimentation that is not intended to benefit the subjects on whom it is performed. Phase I drug studies (CLINICAL TRIALS, PHASE I AS TOPIC) and research involving healthy volunteers are examples of nontherapeutic human experimentation.
Healthy People Programs are a set of health objectives to be used by governments, communities, professional organizations, and others to help develop programs to improve health. It builds on initiatives pursued over the past two decades beginning with the 1979 Surgeon General's Report, Healthy People, Healthy People 2000: National Health Promotion and Disease Prevention Objectives, and Healthy People 2010. These established national health objectives and served as the basis for the development of state and community plans. These are administered by the Office of Disease Prevention and Health Promotion (ODPHP). Similar programs are conducted by other national governments.
