Filter by:In this study patients with 1. chronicle liver diseases - primary biliary cirrhosis - primary sclerosing cholangitis - alcoholic liver cirrhosis - hepatitis b or C - Wilson's disease - cryptogenic cirrhosis 2. Septic Inflammatory Response Syndrome (SIRS) - sepsis - septic shock 3. patients after lysis should be included Blood samples will be gathered from the patients to measure fibrinogen with 5 different methods. The methods are: - Clauss fibrinogen - PT-Derived fibrinogen - immunoturbidimetric method - heat-precipitated fibrinogen - Schulz fibrinogen The result of these tests will be correlated with laboratory values which are gathered in routine and the clinical outcomes.
Polymorphonuclear neutrophils, or granulocytes, are essential effector cells of the innate immune system against bacterial infections. Their role in sepsis has been long established as the primary phagocyte to clear the infectious process. In the early phase of sepsis, one observes a massive recruitment of immature neutrophils from the bone marrow into peripheral blood, the so-called "band forms" or "left shift cells". Despite the daily clinical use of neutrophil band forms count in the care of septic patients and their abundance in septic blood, no information exists on the fate of these cells, nor on their capacity to mount an efficient innate immune response. It is the goal of this proposal to study the fate and the innate immune functions of immature neutrophils obtained in patients with early septic shock. Immature neutrophils will be separated from mature neutrophils. The following functions will be studied ex vivo in mature vs. immature neutrophils from a series of patients with severe sepsis and septic shock: (1) surface expression of receptors of the innate immunity; (2) production of inflammatory mediators and reactive oxygen species in response to bacterial agonists; (3) chemotaxis; (4) phagocytosis of Gram-positive and Gram-negative bacteria; and (5) ex vivo viability (life span) and resistance to apoptosis. Importantly, the investigators have developed and mastered all in vitro assays and cell separation techniques necessary to address and answer these important questions. This project will undoubtedly shed light on the fate and function of a prominent leukocyte population circulating in patients with severe bacterial infections and sepsis.
The purpose of this study is to find out whether acute renal failure is associated with BK virus reactivation in postoperative/posttraumatic critically ill patients with severe SIRS/sepsis and shock.
The purpose of this study is to determine the course of NT-proBNP plasma concentrations in the context of confounding parameters in postoperative/posttraumatic critically ill patients with severe SIRS/sepsis and shock.
The purpose of this study is to clarify the relationship between SIRS (Systemic inflammatory response syndrome) and the infection associated with the use of central venous catheters at Critical Care center in National Defense Medical College, Japan.
BACKGROUND: In November 2003 the Medical Director at Copenhagen University Hospital, Hvidovre, gathered a group of doctors involved in the diagnosis and treatment of patients with sepsis. AMIS: To develop a fast and reliable tool that can guide the physician in the diagnosis and treatment of the septic patient thereby reducing mortality and morbidity. The measurement of markers of inflammation, coagulation, infection and specific bacterial antigens in the same plasma sample will give insight to the pathogenesis of sepsis and SIRS and the bodies responds to the disease. MATERIAL AND METHODES: Case-Control study nested in cohort. 300 patients admitted to the hospital from 1.01.05 to 01.07.06. Copenhagen University Hospital, Hvidovre, an 800 beds hospital, covers a part of Copenhagen with a wide variety in the population's socioeconomic and cultural background. For the analysis of markers the luminex 100 lab analysis system is used. It utilizes xMAP® technology which enables you to simultaneously assay up to 100 analytes in a single well of a microtiter plate, using very small sample volumes. Assay development of a 15-plex is don In-house. COWORKERS & FOUNDING: The following departments at the hospital, are coworkers in the SPEEDI study: Clinical Research Unit, Departments of Infectious Disease, Clinical Microbiology, Clinical Biochemistry, Gastroenterology (incl. surgery), Intensive Care Unit, Emergency Room, and the Hospital Board of Directors. All departments have research experience and a long tradition of publication of scientific works. The study received founding for equipment and salaries during the first phase of the study from the hospitals Board of Directors. Applications to major public foundations in Denmark are awaiting answer. No commercial interest are involved in the study. FUTURE APPLICATIONS: A second phase of the study including children admitted at the hospital is in preparation. The very small sample volume is a great advantage in diagnosing infection in children. The applications of the study results will hopefully provide the physician with the needed tool for a fast and reliable diagnosis, prognosis and treatment guide for the patients suffering from SIRS and sepsis.
