Filter by:Adult cardiac surgery ensures the surgical treatment of valvular and coronary pathologies and of heart failure with the placement of ventricular assistance. Extracorporeal circulation (ECC) is one of the major technical advances associated with cardiac surgery to replace cardiac and pulmonary functions during surgery. ECC can nevertheless lead to postoperative complications, the origin of which is linked to the patient's initial contact with the circuit and membranes of the ECC. This contact triggers a series of humoral and cellular reactions that occur in the first few hours after the ECC and the inflammatory syndrome post ECC fades on its own and usually disappears between the 4th and 6th postoperative day. If the inflammatory response post ECC is most often transient, certain conditions will maintain and intensify this response at the origin of postoperative complications, possibly leading to the patient's death. Among these situations, the investigators find the notion of emergency cardiac surgery, a patient's age over 75 years and a preoperative history of decompensated heart failure, renal failure or type 2 diabetes (T2D). The inflammasome family of receptors of the nucleotide oligomerization domain (NOD) type, pyrin domain containing 3, NLRP3, is a multi-protein platform of recent discovery which plays a major role in the signaling pathways of the innate inflammatory response. The role of the activation of the NLRP3 inflammasome in cardiovascular pathologies is now well established and its metabolic priming by hyperglycemia could explain the greater seriousness of these pathologies in T2D patients due to an exacerbated inflammatory response. What is the effect of T2D status on the inflammatory response post ECC, mediated by the NLRP3 inflammasome, in patients after cardiac surgery?
This is a phase IV, randomized, double-blind, placebo-controlled, three-arm, parallel intervention study including three groups of 25 subjects between 35-65 years of age, treated with either Bend Beauty's Anti-Aging Formula, fish oil control or inert placebo for 90 days, with testing points at baseline, 30, 60, and 90 days.
Retrospective data have shown that active sac management, as applied in EVAS, reduces the incidence of the post-implant syndrome. All-cause and cardiac mortality at one-year seems to be lower after EVAS when compared to EVAR. Ongoing, low grade, inflammation could differ between techniques and induce cardiac damage. This study is designed to establish whether EVAS results in a reduced post-operative inflammatory response during the first year after surgery, compared to EVAR as assessed by trends in circulating inflammatory cytokine concentration. Study design: International prospective, comparative, explorative study. Study population: Patients scheduled to undergo infra-renal EVAR with a polyester endograft or EVAS for an infrarenal aortic aneurysm. This is an explorative study and therefore only patients who would normally receive a suitable device as part of standard treatment at the participating institutes will be recruited. Blood samples will be taken at specified time points before and after surgery. Main study parameters/endpoints: The difference in early post-operative and long term inflammatory response between EVAS and EVAR, measured by the incidence of the post-implant syndrome. To investigate the incidence of the post-implant syndrome, the rise in CRP, WBC and circulating cytokines, at specified time points up to 12 months after surgery and the change in aortic thrombus volume and its relationship with the inflammatory response, measured by cytokines' concentrations.
