Sepsis Clinical Trials

This study is being done to determine if early administration of Midodrine can improve outcomes by maintaining a higher mean blood pressure off of intravenous medications. Researchers want to see if Midodrine can help people with sepsis need fewer vasopressors, which could mean shorter hospital stays, less time with uncomfortable tubes, and a smoother recovery overall.

Norepinephrine is a catecholamine that is the first-line vasopressor for septic shock. The addition of non-catecholamine vasopressors, including vasopressin and angiotensin-II may be used in adults with septic shock that have inadequate mean arterial pressure while on norepinephrine. Uncertainty exists regarding the timing of initiation of these agents and there is a lack of data comparing their safety and efficacy. The current literature suggests that earlier initiation of angiotensin-II will have a more significant reduction on norepinephrine-equivalent dose compared to later initiation. In addition, approximately half of patients initiated on vasopressin do not have an early hemodynamic response 6 hours after initiation. The purpose of this study is to evaluate the efficacy of angiotensin-II when used as the second vasopressor agent for septic shock. Read Less

The long-term goal is to test the clinical efficacy of senolytic therapies to reduce progression to and severity of sepsis in older patients. The central hypothesis is that a threshold burden of SnCs predisposes to a SASP mediated dysfunctional response to PAMPs, contributing to a disproportionate burden of sepsis in older patients. The study hypothesizes timely treatment with fisetin will interrupt this pathway. A multicenter, randomized, adaptive allocation clinical trial to identify the most efficacious dose of the senolytic fisetin to reduce the composite cardiovascular, respiratory, and renal sequential organ failure assessment score at 1 week, and predict the probability of success of a definitive phase III clinical trial.

This is a research study to determine if a particular method of providing nutrition improves the clinical outcomes of patients in the intensive care unit (ICU) who have undergone abdominal surgery and would require nutrition delivered via the bloodstream (called total parenteral nutrition or TPN). The nutrition method we are testing is a structured nutrition delivery plan that involves tube feeding, oral nutrition supplements, and the use of a device (called an indirect calorimeter or IC) to measure calorie needs. This study will also use two devices to measure fat and muscle mass to examine changes during hospitalization. Subjects will be followed throughout hospitalization where nutrition status and fat and muscle mass will be closely monitored. Study activities will begin within 72 hours of a patient's abdominal surgery. TPN (total parenteral nutrition, a method of feeding that bypasses the usual process of eating and digestion) will be started, a non-invasive method of assessing calorie needs (indirect calorimetry (IC)) will be started, a urine sample will be collected to help assist in protein needs, and fat/muscle mass will be measured using bioelectrical impedance analysis (BIA), and an ultrasound. This is a minimal risk study and all products/devices used are non-invasive and FDA-approved. Indirect calorimetry and urine sample collection will be conducted every 3 days during the stay in the Intensive Care Unit - ICU, then every 5 days until hospital discharge. BIA and muscle ultrasound will be conducted every 7 days during ICU stay, then every 14 days until hospital discharge. Read Less

Patients with bloodstream infections (sepsis) have been found in prior studies to have infection-related heart dysfunction, even if they did not have preexisting heart problems. Factors related to the infection may cause the heart to not pump as well as it should, causing critical illness in the form of low blood pressure (shock) and heart failure. Ultrasound is frequently used in the emergency department to evaluate why a patient might have low blood pressure. Part of that evaluation may include obtaining ultrasound images and making measurements about how well or poorly the heart is pumping. The investigators will evaluate a certain measurement that relates to cardiac function, determine how it changes in patients before and after they are treated for septic shock. This will involve placing an ultrasound probe on the patient's chest, measuring the upward and downward movement of the mitral valve, the mitral annulus systolic plane excursion (MAPSE), and comparing the measurements before and after treatment is started. The investigators are attempting to determine if this measurement improves before and after treatment. Read Less

The goal of this observational study is to better understand what happens to circulating blood after a patient experiences severe trauma injury. The main questions it aims to answer are: Is severe human trauma associated with specific patterns of development in the hematopoietic stem cells of these patients? and Does the initial severe trauma injury create immunosuppression and increase risk of in-hospital sepsis? Participants in study will give blood samples and a waste sample of bone marrow at time of operative repair of traumatic orthopedic injuries, supply medical information and participate in surveys and assessments during recovery from their injury(ies). Researchers will compare severe trauma injury patients to elective hip repair patients to see if immunosuppression and specific development patterns occur in the trauma patient versus the otherwise healthy hip surgery patient.

The goal of this observational study is to learn about the utility of biopatches predicting 30-day readmissions in patients discharged from the hospital with sepsis. The main question[s] it aims to answer are: • Does the application of a biopatch provide data that can improve prediction of an unplanned 30-day readmission following a hospitalization for sepsis. Participants will be asked to wear a biopatch on their chest for 30-days following hospital discharge or until readmission to the hospital. Read Less

Researchers think acupuncture may improve outcomes for participants with sepsis, based on laboratory studies and previous studies in people with sepsis. The purpose of this study to see whether real acupuncture can improve outcomes for participants with sepsis when compared to sham acupuncture. Sham acupuncture is performed the same way as real acupuncture but will use different needles and target different sites or places on the body than real acupuncture. Read Less

Adverse outcomes in surgical sepsis patients are secondary to dysregulated emergency myelopoiesis, and expansion of myeloid-derived suppressor cells. Here we propose to determine the underlying mechanisms behind the increased expansion of these leukocyte populations and the underlying mechanisms that drive inflammation and immune suppression.

Prospective observational cohort study; pediatric sepsis vs. healthy pediatric subjects and pediatric sepsis with acute kidney injury (AKI) vs without AKI. Blood samples and renal ultrasound will be collected on sequential days for septic subject and one time for the healthy patients. Enzyme-linked immunosorbent assays (ELISA) with be run on serum plasma to compare the renin-angiotensin-aldosterone system (RAAS) between groups. Read Less

Purpose: To assess the prognostic role of Handheld Vital Microscopy (HVM) and evaluate levels of endothelial glycocalyx (eGC) breakdown in patients demonstrating Hemodynamic Incoherence (HI), to elucidate a mechanistic link between the eGC and HI in order to inform prognostic enrichment of future resuscitation trials. We will serially evaluate microhemodynamics (MiH) and macro hemodynamics (maH) and the perfused boundary region (PBR, an visual proxy for eGC thickness) using HVM, and a validated circulating biomarker of eGC integrity.

Extracorporeal membrane oxygenation (ECMO) is a form of cardiopulmonary life-support for critically ill patients where blood is extracted from the vascular system and circulated by a mechanical pump while it is oxygenated and reinfused into the patient's circulation. It is well known that critically ill patients may experience alterations in antibiotic pharmacokinetics, and as a result, dosing modifications are generally required. There is a need to understand how ECMO circuits affect the pharmacokinetics and disposition of drugs. This study is designed to assess the pharmacokinetics of the new broad-spectrum antibiotic, Cefiderocol, in critically ill patient receiving ECMO. Read Less
