Filter by:Systemic hyperinflammatory states, e.g. triggered by infection/sepsis, represent a major challenge for modern medicine. After an initially localized onset, inflammation can extend to an excessive, uncontrolled inflammatory reaction affecting the entire body and can trigger circulatory failure with subsequent irreversible multiple organ failure. Despite all the medical advances made in recent years, sepsis continues to be a substantial problem, as almost all therapeutic approaches have failed to prove their efficacy to date. Mortality in this clinical entity thus remains extremely high. In Germany alone, more than 100,000 people suffer from sepsis or septic shock every year, nearly half of whom die despite optimal therapy. Thus, sepsis is the third most common cause of death, has major importance both from a medical but also from an economical viewpoint, and approaches that could contribute to its successful treatment need to be further developed and explored. If a patient experiences the spread of bacteria or their constituents in the blood stream due to an uncontrolled source of infection, the result is a deliberately triggered physiological defense reaction of the body. In many patients, however, there is a pathological dysregulation of these mechanisms, in a way that the defense reaction goes far beyond the physiological level required, resulting in an excessive immune response of the body, which is mainly facilitated by inflammatory mediators such as cytokines and chemokines. The immune response spreads throughout the body and also dissipates into organs unaffected by the original infection. In cases of such unwanted overshooting immune responses, an attempt to regain control of the described deleterious systemic events seems reasonable by removing the excess amount of cytokines from the blood, thus preventing or treating organ failure. In this context, current therapeutic approaches increasingly focus on the elimination of inflammatory mediators. In recent years, hemoadsorption, using a new adsorber (CytoSorb), has been used to treat sepsis and other conditions of hyperinflammation. The advantage of this therapeutic principle is that a wide range of inflammatory mediators are removed. In conjunction with the enormous elimination capacity, the effective and rapid reduction of mediators can be achieved. To date, there have been more than 61,000 treatments using this procedure worldwide without device-related side effects being reported. The investigators have been treating patients with this procedure for over 5 years with consistently very favorable results. Therefore, the investigators would like to expand and deepen their observations with the proposed project.
A multicenter, randomized, double-blinded, placebo-controlled study of two dosing frequencies of recombinant Interleukin-7 (CYT107) treatment to restore absolute lymphocyte counts in sepsis patients; IRIS-7B (Immune Reconstitution of Immunosuppressed Sepsis patients). A parallel study will be performed in France to allow a common statistical analysis of the primary end points and analysis for the enrolled patient population.
Prospective studies on the incidence of VTE during severe sepsis and septic shock remain absent, hindering efficacy assessments regarding current VTE prevention strategies in septic patients. The investigators will prospectively study consecutively enrolled ICU patients with severe sepsis and septic shock admitted at three hospitals. All patients will provide informed consent and the study will be IRB approved. VTE thromboprophylaxis, provided per standard of care and according to the patients' primary team, will be recorded for all patients. Patients will undergo bilateral lower (and upper, if a central venous catheter [CVC] was present) comprehensive compression ultrasonography (CUS) and will be followed for symptomatic deep vein thrombosis (DVT) and pulmonary embolism (PE) prior to discharge. The investigators will perform multivariate regression analyses to identify predictors of VTE.
Sepsis is a clinical syndrome which infection trigger systemic inflammatory response. Uncontrolled inflammatory process leads to multiple organ dysfunction and cause early mortality in severe sepsis. Unfractionated heparin is an anticoagulant that widely used either for DVT prophylaxis or treatment of disseminated intravascular coagulation. Heparin also have an anti-inflammatory effect through downregulates nuclear factor kappa B and tumor necrosis factor alpha. Aim of this study is to determine effects of low dose unfractionated heparin treatment on inflammation in severe sepsis patient.
