The aim of the proposed study is to examine the effect of DEX on the inflammatory response in major surgery. More importantly, the investigators will correlate changes in the concentration of inflammatory mediators with meaningful clinical outcomes.
The human body knows a biphasic immunological reaction to sepsis. First, the pro-inflammatory reaction takes place, marked by the release of pro-inflammatory cytokines like TNF-α, as a reaction to the bacterial toxins. Secondly, the counter regulatory anti-inflammatory reaction arises. This phase is acting as negative feedback on the inflammation by inhibition of the pro-inflammatory cytokines. This is called "immunoparalysis", a pronounced immunosuppressive state, which renders patients vulnerable to opportunistic infections. Most of the septic patients survive the initial pro-inflammatory phase, but die during this second stage.Research in the past has shown that immunostimulatory therapy with GM-CSF or IFN-γ has promising effects on the pro-inflammatory reaction during immunoparalysis ex vivo. Both drugs are known for their immunostimulatory effects. Recent pilot studies have showed in septic patients, that long-lasting monocyte deactivation in sepsis ex vivo can be reversed by these two immunostimulants. However, the mechanism and extent of immunoparalysis recovery may be different between the two compounds. Previously it has been shown that human endotoxemia (induced by LPS), leads to marked immunosuppression in healthy individuals, characterized by a transient refractory state to a subsequent LPS challenge (endotoxin tolerance). Consequently, human endotoxemia can serve as a standardized, controlled model for sepsis-induced immunoparalysis. Until now, all studies have focused on the ex vivo tolerance. However, we have recently proved, that the ex vivo condition is not completely representative for the in vivo situation. Ex vivo, leukocyte tolerance to LPS resolves within one day, while the in vivo immunoparalysis persists for two weeks. In this project, we will investigate the effects of both GM-CSF and IFN-γ in a parallel double-blind placebo controlled randomized manner on the immunoparalysis following human endotoxemia, both in-vitro and in vivo. As a result, we hope to get more insight in the pathophysiology of sepsis-induced immunoparalysis and thereby develop new immunostimulatory therapies that improve patient outcome
Infection remains a difficult-to-treat complication of total knee arthroplasty. The gold standard treatment is two-stage removal of the prosthesis with later replacement of permanent implants. The first stage consists of removal of the infected arthroplasty components and the surrounding devitalized tissue, copious pulsed irrigation, and placement of a temporary antibiotic-impregnated cement spacer. This spacer typically is left in place six weeks, during which time the patient receives intravenous antibiotics. After the surgeon feels that the infection has been eradicated, or if the patient requires repeat debridement, a second operative procedure is performed. While the use of an antibiotic-loaded spacer is well accepted, whether the spacer should immobilize the knee (a so-called "static" spacer) or allow for range of motion (a so-called "articulating" spacer) is controversial. Proponents of articulating spacers argue that they prevent scarring of the musculature surrounding the knee resulting in easier reimplantation, improved long-term knee function, and improved range of motion. Proponents of static spacers argue that immobilization of the periarticular soft tissues aids in clearance of the infection and is simpler to fashion intraoperatively. While good results have been described with both methods, comparative trials have been conflicting as to whether spacer design alters knee function, operative time, and range of motion. Equipoise exists within the literature, and no randomized clinical trial has been conducted to evaluate this issue. The purpose of this study is to compare articulating and static antibiotic-impregnated spacers for the treatment of chronic periprosthetic infection complicating total knee arthroplasty through a prospective, randomized clinical trial. The goals of this trial are to determine the effect of spacer design upon eradication of infection, knee function, ease of reimplantation, and range of motion. The investigators hypothesize that articulating spacers will provide shorter operative times at reimplantation, while improving knee function and range of motion.
Infection remains one of the most difficult-to-treat complications of total hip arthroplasty. The gold standard treatment is two-stage removal of the prosthesis with later replacement of permanent implants.The first stage consists of removal of the infected arthroplasty components and the surrounding devitalized tissue, copious pulsed irrigation, and placement of a temporary antibiotic-impregnated cement spacer. This spacer is typically left in place six weeks, during which time the patient receives intravenous antibiotics. After the surgeon feels that the infection has been eradicated, or if a second debridement is required, a second operative procedure is performed. While the use of an antibiotic spacer is well accepted, whether the spacer should immobilize the hip (a so-called "static" spacer) or allow for range of motion (a so-called "articulating" spacer) is controversial. Proponents of static spacers argue that immobilization of the periarticular soft tissues aids in clearance of the infection and that these spacers are simpler to fashion intraoperatively. Proponents of articulating spacers argue that they improve hip function, prevent damage to the musculature surrounding the hip, allow easier reimplantation, improve hip function, and prevent dislocation following hip reimplantation. While good results have been described with both methods, comparative trials have been conflicting as to whether spacer design alters hip function, operative time, and dislocation rates. Equipoise exists within the literature, and no randomized clinical trial has been conducted to evaluate this issue. The purpose of this study is to compare articulating and static antibiotic-impregnated spacers for the treatment of chronic periprosthetic infection complicating total hip arthroplasty through a prospective, randomized clinical trial. The goals of this trial are to determine the effect of spacer design upon eradication of infection, hip function, ease of reimplantation, and dislocation rates. The investigators hypothesize that articulating spacers will provide shorter operative times at replantation while improving hip function and hip dislocation rates following hip reimplantation.
This is the first clinical trial with NOX-H94. The purpose of this clinical trial is to identify a safe and efficacious treatment regimen for the clinical development of NOX-H94 in patients with anemia of chronic disease (inflammation).
This trial is conducted in Europe. The aim of this dose-escalating trial is to assess the safety, tolerability, pharmacokinetics (the rate at which the body eliminates the trial drug) and pharmacodynamics (the effect of the investigated drug on the body) of single and repeated doses of NNC141-0100 in subjects with Rheumatoid Arthritis.
Despite the pathophysiology of IBS remains largely unsettled, several mechanisms have been proposed to explain symptom generation. These include psychosocial factors, altered gastrointestinal motor function and altered perception of visceral stimuli because of chronic low-grade inflammation and increased nociceptive mediator release by inflammatory cells, particularly mast cells. The aim of this pilot study is to provide evidence of: 1. intestinal mast cell (MC) infiltration and activation in IBS patients; 2. down-modulation of MC activation by the oral administration of the association of palmitoylethanolamide (PEA) and polydatin in IBS patients.
Background: Contrast-enhanced ultrasound (CEUS) visualization of the adventitial vasa vasorum. Late phase CEUS detect inflammation by visualizing microbubbles phagocytosed by monocytes. The inflammatory process of the vessel wall associated with perivascular angiogenesis at the time of deep venous thrombosis (DVT) and superficial vein thrombophlebitis (SVT) may important in the development of post-thrombotic syndrome (PTS). Therefore the investigators will test the value of CEUS to detect venous perivascular vascularization and inflammation in patients with acute DVT or SVT. Aims: To determine the presence and degree of venous perivascular vascularization and inflammation assessed with CEUS in patients with acute DVT or SVT, and compare this to controls without thrombosis. Expected results: The investigators hypothesize that venous perivascular vascularization and inflammation assessed by contrast agent enhancement can be quantified and will be significantly more pronounced in the perivascular tissue of the thrombotic vein than in the non affected vein and in controls, and will correlate with level of inflammatory markers and leg volume. Significance: These results would provide new information on the pathophysiological concept of thrombosis and thrombus resolution. It might help to better understand the pathophysiologic mechanisms that promote the development of chronic venous insufficiency and PTS.
