Sepsis is a dysregulated host response to infection that leads to life-threatening organ dysfunction and represents a major healthcare problem. Septic shock is the most severe form, characterized by increased capillary permeability and vasodilation, resulting in hypotension and tissue hypoxia. Early identification and treatment of tissue hypoperfusion are pivotal components of initial resuscitation to limit progression to multiple organ dysfunction and death. The 2021 Surviving Sepsis Guidelines recommend guiding initial resuscitation by targeting decreases in serum lactate levels in patients with elevated lactate. However, although elevated lactate levels may reflect tissue hypoxia, serum lactate is not a direct marker of tissue perfusion. Hyperlactatemia may be attributable to mechanisms other than tissue hypoperfusion, such as accelerated aerobic glycolysis driven by excessive β-adrenergic stimulation or impaired clearance (e.g., in liver failure). The venous-to-arterial carbon dioxide partial pressure difference (CO₂ gap), which is inversely related to cardiac output, has been shown to reflect the adequacy of venous blood flow to remove CO₂ from tissues. The CO₂ gap is closely linked to microcirculatory blood flow during the early resuscitation phase of septic shock and may effectively identify persistent tissue hypoperfusion in shock states. A persistently high CO₂ gap during early resuscitation has been associated with significantly higher 28-day mortality and increased Sequential Organ Failure Assessment (SOFA) scores. Moreover, the CO₂ gap has been shown to respond to changes in cardiac output during inotrope infusion in patients with low blood flow, suggesting that its assessment could be useful for therapeutic adjustments. Therefore, there are compelling arguments to evaluate the usefulness of the CO₂ gap in guiding early resuscitation in patients with septic shock. The investigators postulated that CO₂ gap-guided early resuscitation may be more effective in improving outcomes than lactate-guided resuscitation.
NCT07383103
The purpose of this study is to evaluate the efficacy and safety of the combination therapy of hydrocortisone and fludrocortisone among adult patients with septic shock.
NCT07406750
Sepsis is a serious condition where the body's immune response to infection overreacts, leading to organ damage and death. Venous congestion, a buildup of blood in the veins, can occur in sepsis and contribute to organ injury. VExUS (Venous Excess Ultrasound Score) is an ultrasound method that can detect congestion early. This study examines whether ICU nurses, after training, can perform VExUS reliably, explores their experiences, and investigates links between VExUS findings and clinical outcomes.
NCT07418541
Septic shock is a life-threatening condition that can cause severe circulatory failure and damage to vital organs, including the kidneys. One of the most serious complications of septic shock is acute kidney injury (AKI), which is associated with increased morbidity and mortality. This study aims to evaluate the effect of early co-administration of crystalloid fluid resuscitation (30 mL/kg body weight) and norepinephrine on preventing acute kidney injury and improving hemodynamic stability in adult patients with septic shock. Patients will receive standard initial fluid resuscitation combined with early norepinephrine infusion according to a predefined clinical protocol. Changes in blood pressure, urine output, and other hemodynamic parameters will be observed before and after the intervention. The findings of this study are expected to provide evidence to support early hemodynamic optimization strategies for reducing the risk of acute kidney injury in septic shock patients.
NCT07388628
The objectives of this registry study are to: 1. Record real-life data related to the use of the ARTICE® therapy in sepsis subjects. 2. Further evaluate ARTICE® treatment efficacy. 3. Identify potential sub-groups, assess their risk-benefit- and safety profile. 4. Changes in SOFA score D0 to SOFA Score D7.
NCT01682590
The purpose of this multicentric, randomized controlled trial is to assess whether the timing of renal replacement therapy initiation (early vs delayed) has an impact on mortality at 90 days in patients with severe acute kidney injury at the failure stage (according to RIFLE criteria) during the initial phase of septic shock.
NCT03953677
Septic shock is common in patients admitted to intensive care and hospital mortality occurs in close to 50% of these patients. In half of the cases, death occurs within the first 72 hours in a context of multiple organ failure that does not respond to conventional therapies, particularly circulatory therapies, despite increasing doses of catecholamines. Vasopressor resistance in septic patients defines refractory septic shock. In one study (Conrad et al. 2015), the increase in blood pressure observed with an infusion of increasing doses of phenylephrine (dose-response curve) made it possible to quickly and clearly identify patients resistant to vasopressors at a high risk of death by refractory shock (ROC AUC 0.92). This resistance is due in particular to a downregulation of α1 adrenergic receptors, linked to sympathetic hyper activation associated with septic shock. To date, there is no validated therapy in this situation. However, experimental data have shown that the administration of α2 agonists, usually used for their sedative (dexmedetomidine) or anti-hypertensive (clonidine) effect, normalizes sympathetic activity towards basal values. In animals, α2 agonists restore the sensitivity of alpha1 adrenergic receptors, resulting in improved vasopressor sensitivity and survival. In humans, a beneficial effect on mortality was suggested in the first trial testing dexmedetomidine in septic patients in 2017. This effect was observed especially in the most severe patients, suggesting a restoration of sensitivity to vasopressors. The hypothesis is that the administration of dexmedetomidine in patients in refractory septic shock may improve response to phenylephrine and decrease resistance to vasopressors. This pilot study could lay the foundation for a randomized controlled trial.
NCT06464510
The norepinephrine and vasopressin for rescue versus early vasopressin for vasopressor dependent sepsis (NoVa) is a phase 3, multicenter, open-label, randomized controlled trial comparing an early vasopressin initiation strategy versus norepinephrine plus vasopressin initiation only as a rescue strategy for hemodynamic management of critically ill patients with vasopressor dependent sepsis.
NCT07343206
The goal of this clinical trial is to determine whether early initiation of norepinephrine with rapid dose adjustment improves clinical outcomes in adult patients with septic shock. The study aims to evaluate the effect of early norepinephrine administration on mortality, hemodynamic stabilization, and resuscitation efficiency in adults aged 18 years and older diagnosed with septic shock. The main questions it aims to answer are: * Does early norepinephrine administration with rapid dose titration reduce 28-day mortality compared with standard treatment? * Does early norepinephrine administration with rapid dose tiration lead to faster shock control and reduced fluid requirements without increasing treatment-related adverse events? Researchers will compare early norepinephrine administration with rapid dose adjustment to placebo with standard sequential resuscitation and rescue norepinephrine as needed to see if early vasopressor initiation improves survival, shock resolution, and safety outcomes. Participants will: * Receive either norepinephrine or placebo infusion initiated within one hour of septic shock diagnosis, with dose adjustment every 15 minutes according to a standardized protocol * Undergo close hemodynamic and safety monitoring, including frequent vital sign assessment and limb perfusion evaluation * Receive standard sepsis care, including fluid resuscitation, antibiotics, and organ support as clinically indicated * Be followed for clinical outcomes and adverse events for up to 28 days after enrollment
NCT07264543
The aim of the study is to evaluate the viability and feasibility of its protocol in order to conduct a larger clinical trial to assess whether methylene blue can improve patient-centered clinical outcomes such as mortality or length of hospital stay in septic shock patients.
NCT03901807
Prospective, multicenter, randomized, open-label study of standard of care plus the PMX cartridge versus standard of care alone in patients with endotoxemic septic shock
NCT05874895
Antimicrobial and supportive therapeutic interventions in patients with septic shock are usually effective - procalcitonin and interleukin-6 levels fall rapidly in most cases, and noradrenaline support can be discontinued within a few days. Unfortunately, only in a small portion of patients, do the organ functions improve at the same time, and in most of them, multi-organ failure persists. Therefore, it is likely that, in addition to infection and the response to infection, other mechanisms are also involved in the persistence of organ failure in patients after septic shock.
NCT07245550
A dysregulated host response to infection results in organ failure and sepsis, a potentially fatal illness. Sepsis killed about 11 million people worldwide in 2017 and had a death rate close to 20 %
NCT02473263
The purpose of this study is to determine whether an aggressive strategy of severe sepsis patients since pre hospital care, including early antibiotics administration, hemodynamic optimization, and opotherapy when indicated, could reduce mortality
NCT07212582
This study will test whether giving human albumin to keep the blood albumin level above 3.5 g/dL, in addition to standard care, improves survival in patients with surgical septic shock. Septic shock is a life-threatening complication of infection that often requires urgent surgery and intensive care. Current treatment guidelines recommend intravenous fluids and medications to support blood pressure, but the best type of fluid is still uncertain. Human albumin is a natural protein in the blood that helps maintain fluid balance and has anti-inflammatory effects. Previous studies suggest that low albumin levels are linked with worse outcomes in septic patients, and that albumin infusion might improve recovery, but results are mixed and evidence in surgical septic shock patients is lacking. In this randomized controlled trial, adult patients with surgical septic shock admitted to the surgical intensive care unit will be randomly assigned to receive either standard care alone or standard care plus 20% human albumin solution for up to 3 days. The main outcome is survival at 28 days. Secondary outcomes include length of ICU and hospital stay, need for dialysis, ventilator-free days, vasopressor-free days, fluid balance, gastrointestinal recovery, and adverse reactions. The results of this study will help determine whether targeted albumin replacement is beneficial in critically ill surgical patients with septic shock and could guide future fluid resuscitation strategies.
NCT07230041
The purpose of this study is to measure the change in plasma concentrations of antibiotics used during passage through the CRRT filter and hemadsorption cartridge in patients with septic shock and renal failure requiring CRRT. All patients aged \> 18 years, admitted to the ICU, diagnosed with septic shock and renal failure requiring CRRT, receiving antibiotic therapy with at least one of the following drugs: meropenem, linezolid, and daptomycin, who provided informed consent, are included in the study. Patients not admitted to the ICU, patients with renal failure not requiring CRRT, patients aged \< 18 years, or those who did not provide informed consent are excluded. The enrollment period will last 12 months and will run from September 2024 to September 2025. The expected number of patients enrolled is twenty. To proceed with the study, after starting antibiotic therapy, a 4 ml dose of blood will be drawn (Vacuette tube ref. 454092) before the cartridge, immediately after, and after the dialysis filter. This measurement will be repeated after 4, 8, and 12 hours, which represents the maximum usage time of the cartridge. After 12 hours, the cartridge becomes saturated and loses its adsorption capacity. The CRRT filter, however, remains in place for at least 72 hours before being replaced. Treatment is maintained until clinically necessary. For patients in intensive care, several blood samples are required throughout the day, both with a blood sample sent to the biochemistry laboratory every 6-8 hours to check clinical conditions, and with an arterial blood sample (blood gas) to check respiratory and metabolic status in patients on mechanical ventilation. Furthermore, in patients undergoing CRRT, electrolyte balance must be monitored every 4 hours. Therefore, the blood sample for the study inevitably coincides with one of the routine blood samples. The test tube, labeled with a unique code, will be sent to the central laboratory, which will centrifuge the blood and extract the plasma. This aliquot will then be stored at -80°C in a dedicated space and sent to the designated laboratory upon analysis. Determination of the plasma dosage of the antibiotic in use is commonly performed on patients admitted to the Intensive Care Unit, where clinically necessary. Participation in the study does not change current clinical practices.
NCT07184593
The goal of this observational study is to evaluate whether whole blood H3.1 nucleosome levels can predict 30-day mortality in adult critically ill patients admitted to the ICU with conditions such as sepsis, septic shock, cardiogenic shock, severe trauma, post-cardiac arrest, acute brain injury, or severe acute pancreatitis. The main questions it aims to answer are: Do initial whole blood H3.1 nucleosome levels predict 30-day mortality in critically ill patients? Are whole blood nucleosome measurements using a novel point-of-care device correlated with traditional plasma chemiluminescence immunoassays (ChLIA)? If there is a comparison group: Researchers will compare point-of-care whole blood nucleosome results with plasma ChLIA assays to see if the device provides reliable and feasible bedside measurements. Participants will: Provide blood samples at admission, 6h, Day 1, Day 3, and Day 7 for nucleosome analysis. Undergo point-of-care H3.1 nucleosome measurement and parallel plasma storage for ChLIA testing. (If applicable, in acute brain injury patients with external ventricular drains) provide daily cerebrospinal fluid samples until Day 5, only if otherwise discarded. Have standard ICU data (SOFA, SAPS II, etc.) collected as part of routine care.
NCT04589546
Sepsis 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.
NCT07136532
The goal of this study is to evaluate the role of carotid Doppler and Echocardiography as a predictor of fluid responsiveness in paediatric patients with septic shock. and To evaluate the diagnostic accuracy of Aortic peak velocity and velocity time integral (VTI)variation in patients with septic shock during their fluid resuscitation phase as a reliable predictor of fluid responsiveness.
NCT07052084
Septic shock is a syndrome associated with severe infection and a mortality rate of approximately 45%. In line with current recommendations, norepinephrine is the first-line vasopressor used in patients with septic shock. In a previous study, norepinephrine doses above 1 µg/kg/min were associated with mortality rates over 90%. In the same study, doses above 0.3 µg/kg/min were associated with a mortality rate of 40%. An increased mortality compared to the general 40% mortality of septic shock appears to be associated with norepinephrine doses as low as 0.3 µg/kg/min. Vasopressin stimulates V1 receptors, primarily located on vascular smooth muscle cells. When V1a receptors are stimulated, they induce vasoconstriction by activating protein kinase C via a Gq protein and various second messengers. Its use is validated in refractory shock states by international guidelines as a second-line vasopressor. This indication was further reinforced in the 2021 update of the septic shock management recommendations. The VASST study, a randomized controlled trial, assessed the effects of vasopressin versus norepinephrine in septic shock. It found no overall difference in mortality between the two groups. However, in less severe cases where norepinephrine doses were below 14 µg/min before randomization, vasopressin was associated with significantly lower mortality, suggesting potential benefits from early introduction of a second vasopressor. The VANISH trial failed to confirm this hypothesis, possibly due to broad inclusion criteria and unclear protocol regarding the combined use of both agents. Our hypothesis is that (1) vasopressin is beneficial when used synergistically with norepinephrine; (2) due to its negative effect on cardiac output (as shown in previous studies), vasopressin should only be administered to patients in the hyperdynamic phase of septic shock. The hypothesis is that the systematic addition of vasopressin to norepinephrine therapy in a hyperdynamic septic shock subpopulation would improve patient outcomes.
