Septic patients with acute kidney injury (SA-AKI) requiring continuous renal replacement therapies (CRRT) present high mortality due to systemic inflammatory response, cytokine liberation, and finally multiorgan dysfunction. Cytokine plasmatic elimination with continuous venovenous hemofiltration (CVVH) presents a high resource cost both technical and human. The study primary end-point is to demonstrate a similar cytokine removal of continuous venovenous hemodialysis (CVVHD) respect to CVVH, both modalities employing the same adsorption capacity membrane. As secondary end-points investigators will try to demonstrate technical superiority of CVVHD respect to CVVH. In order to achieve these objectives investigators have designed a proof of concept exploratory trial that will include those participants whom present SA-AKI meeting CRRT initiation criteria. During the first 72 hours investigators will measure plasmatic elimination capacity of main cytokines, and other clinical and prognostic relevant molecules. Investigators wil measure mean filter life during all CRRT with special attention to the first 72 hours. Investigators will also measure hemodynamic, respiratory, and metabolic parameters. Finally, investigators will analyze 90 days survival. Demonstration of a similar immunomodulating capacity and a minor complication rate with its consequent lower cost, should settle the based evidence principles that recommend the use of CVVHD associated to an adsorption capacity membrane in patients with SA-AKI whom need CRRT.
Periprocedural bleeding events are frequent during transcatheter aortic valve implantation (TAVI), mainly driven by vascular complications and are associated to a worse prognosis. Therefore, red blood cell (RBC) transfusion is often required, although it is associated with worsened outcomes. There is no consensus on the optimal transfusion strategy after bleeding. The Transfusion Requirements in Transcatheter Aortic Valve Implantation (TRITAVI) will be a multicenter retrospective registry enrolling consecutive patients who underwent TAVI; the primary aim of the study will be to test whether RBC transfusion is a marker or an independent predictor of adverse events.
Acute Kidney Injury (AKI) is a common and serious post operative complication and may occur in up to 50% of all patients undergoing cardiac surgery and is associated with 8% mortality rate compared with 0.9% in non-affected patients and remains a major factor for post surgery adverse outcomes. Early interventions to prevent postoperative AKI can help decreasing morbidity and mortality in these patients. Using cardiopulmonary bypass during cardiac surgery triggers systemic inflammatory response and recruits pro-inflammatory cytokines such as tumor necrosis factor, interleukin -10 (IL-10) and Interleukin-6 (IL-6) accompanying with production of free oxygen radicals which provokes oxidative stress in the milieu of ischemic reperfusion injury. Pentoxifylline as a non-specific phosphodiesterase inhibitor, can suppress the production of some factors of inflammatory response and oxidative stress, probably prevent post surgery AKI with these mechanisms.
