iSGLT2 in Prevention of Acute Kidney Injury in Patients With Diabetes Mellitus Undergoing CABG Extracorporeal...
Diabetes MellitusType 23 moreIntroduction: Diabetes Mellitus (DM) is a condition known to be associated with coronary artery disease (CAD) and its role as promoter of atherosclerosis is well stablished. The revascularization surgery is commonly indicated to patients with multivessel coronary disease and kidney injury is a prevalent complication in post operation. This work aims to evaluate the impact of a strategy to control Diabetes Mellitus using inhibitors of sodium-glucose cotransporters (ISGLT2) in diabetics patients with assigned myocardial revascularization with cardiopulmonary bypass
Comparison of Biphozyl® and Phoxilium® as a Replacement Fluid During CVVH for AKI in Adults and...
Critically IllAcute Kidney Injury8 moreThe primary objectives of the BiPhox-Trial are to demonstrate, that the use of Biphozyl® as a replacement fluid in adult critically ill acute kidney injury (AKI) patients, results in a lower rate of pH excursions and of bicarbonate (HCO3-) excursions compared to the use of Phoxilium® during the studied continuous veno-venous hemofiltration (CVVH) interval with regional citrate anticoagulation (RCA). The secondary objectives of the BiPhox-Trial are to evaluate the time to pH level normalization and the HCO3- substitution rates after initiation of CVVH treatment. Further, to demonstrate that the use of Biphozyl® as a replacement fluid in adult critically ill AKI patients, results in a more stable acid-base-status as well as improved respiratory situation due to lower intracorporeal HCO3- and carbon dioxide levels compared to the use of Phoxilium® during the studied CVVH interval with RCA.

Acute Kidney InjuryKidney Replacement1 moreA pilot randomized clinical trial comparing a protocol-based fluid management strategy to usual care in critically ill patients receiving kidney replacement therapy. The fluid management protocol is intended to achieve neutral or negative daily fluid balance by both preventing and treating fluid accumulation.
Does High-dose Vitamin B3 Supplementation Prevent Major Adverse Kidney Events During Septic Shock?...
Acute Kidney InjurySeptic Shock2 moreSepsis is the most common cause of acute kidney injury (AKI) in critically ill patients and is associated with a high mortality rate. Currently there is no available specific treatment to prevent or treat AKI in this setting. Many experimental and clinical data suggest that Nicotinamide, a safe and inexpensive vitamin, could be effective to prevent major adverse kidney events during septic shock. The main objective of the study is to show the superiority of Nicotinamide supplementation compared to the placebo group, in patients with septic shock admitted to intensive care. A 15% reduction in the incidence of major renal adverse events at day 30 is expected in the "Nicotinamide" group.
Patients Undergoing Continuous Venovenous Hemodiafiltration: Effects of Increased Blood Flow
Acute Kidney InjuryAcute Kidney Injure (AKI) is a syndrome with high incidence and prevalence in Intensive Care Units (ICU). It is estimated that 50% of the in the sector present AKI at some point and 10 to 15% require renal replacement therapy (RRT). Although studies do not show the superiority of continuous methods, the most severely ill patients are directed to this type of RRT. A disadvantage of continuous therapies is the need for anticoagulation. Critically ill patients have a pro-clotting state (inflammation) and several risk factors for bleeding (coagulopathies, postoperative, large vessel puncture). On the one hand, ineffective anticoagulation compromises the efficiency of the procedure, shortens the life of the extracorporeal system, consumes resources and increases blood loss due to unexpected and early filter clotting. There is no consensus on what would be the optimal blood flow (Qb) in continuous dialysis, especially when regional citrate anticoagulation (RCA) is used. Theoretically, a higher flow rate would prevent stasis in the system and decrease the risk of filter clotting. Studies show conflicting results. Increasing Qb from 150 to 250 mL/min showed that circuit life and the chance of coagulation were similar. On the other hand, blood flow is important for maintaining the filtration fraction (FF), the ratio of ultrafiltrate flow to plasma flow. Ideally, the FF should be kept below 25% to avoid hemoconcentration and coagulation of the filter. Therefore, the higher the convection rate, the higher the blood flow should be to keep the FF in the optimal range. Since the anticoagulation capacity of citrate is dependent on its concentration, around 4 mmol/L of blood, by increasing the blood flow, the citrate infusion is proportionally increased. Theoretically, the higher citrate load offered should be metabolized and, in theory, could cause its overload with the occurrence of metabolic alkalosis and hypernatremia. This situation occurs when its maximum metabolizing capacity is not reached and there is an excess of citrate infusion relative to the buffering requirement. Thus, we intend to evaluate filter useful life, metabolic control, electrolyte profile and acid-base balance in ICU patients undergoing continuous venovenous hemodiafiltration (CVVHDF), regional citrate anticoagulation during blood flow augmentation.

Acute Kidney InjuryHepatorenal SyndromeThis research study is being done to learn what effect 7 days of treatment with the Selective Cytopheretic Device (SCD) will have on these white blood cells in the bloodstream of patients with hepatorenal syndrome and to learn whether it has any effect on the blood circulation and kidney function.
Discontinuing CRRT in Patients With Acute Kidney Injury
Acute Kidney InjuryIn this study, investigators are going to test whether a standardize approach to discontinuation of Continuous Renal Replacement Therapy (CRRT) using a set of criteria improves outcomes. These criteria are based on the best available evidence. In a systematic review, aside from urine output, there was no one factor that predicted successful weaning of RRT in patients with AKI. Urine output prior to discontinuation of RRT was the most commonly described and robust predictor. The pooled analysis found a sensitivity of 66.2% and specificity of 73.6% for urine output to predict successful RRT discontinuation. Patients with AKI on CRRT recruited during the first half of the study will be controls (usual process of care). After accrual, patients recruited for the second half will receive the intervention where discontinuation of CRRT will be guided by a set of criteria based on the patient's hemodynamic status and other factors.
Regional Citrate Anticoagulation for RRT During V-V ECMO
ARDSHuman1 moreAnticoagulation is an essential component of all extracorporeal therapies. Currently locoregional citrate anticoagulation is the recommended technique for continuous renal replacement therapy (CRRT). However, low clearance of citrate restricts its use to blood flow up to 150 mL/min, preventing its use in ECMO. Renal replacement therapy (RRT) is commonly provided to ECMO patients with AKI. In presence of systemic heparinization for ECMO, additional anticoagulation for the CRRT circuit (i.e. RCA) is usually not employed. Nevertheless, thrombosis occurs more frequently in the CRRT circuit than the oxygenator because of the slower blood flow. The aim of this prospective, cross-over study is to assess, in patients undergoing CRRT during veno-venous ECMO (vv-ECMO), the efficacy and safety of adding regional citrate anticoagulation (RCA) for CRRT circuit anticoagulation.
