Toxicokinetics of Protein-bound Uremic Toxins in ESRD Patients
Uremic; ToxemiaPharmacokinetics1 moreProtein-bound uremic toxins (PBUTs) are important uremic toxins, represented by indoxyl sulfate (IS), derived from the fermentation of dietary proteins by gut bacteria. The purpose of this study was to study the changes of IS in maintenance hemodialysis patients, and to construct a metabolic kinetics model of IS clearance. The model was then used to estimate the clearance rate of indoxyl sulfate by hemoperage, and to verify the application value of the model. This study intends to collect a series of serum, dialysate and urine samples from maintenance hemodialysis patients receiving high-throughput dialysis or hemodialysis filtration, so as to clarify the variation rule of IS during various blood purification treatments. Furthermore, a three-compartment model of dialysis IS metabolism kinetics was constructed according to the IS clearance of dialysis and residual kidney, and the above model was verified internally and externally. Finally, the model's fit and predictive value were validated in a group of MHD patients treated with HP without residual kidney.
Neutrophil Elastase Inhibitor in Treatment of ARDS Patients With Mechanical Ventilation Caused by...
Acute Respiratory Distress SyndromeSepsis is a life-threatening organ dysfunction caused by the host's maladjusted response to infection. It is one of the common clinical critical diseases, often accompanied by multiple organ failure, immune imbalance and high mortality. Sepsis is a syndrome of physiological, pathological and biochemical abnormalities caused by infection. Its incidence rate and prevalence have been on the rise in the past few years. Sepsis has greatly endangered the lives and health of the public. Among them, ARDS is a fatal complication of sepsis and a common critical illness syndrome in ICU. At present, the conventional treatment for ARDS caused by sepsis is still limited to indirect supportive therapy such as primary disease treatment, infection control, mechanical ventilation support, and nutrition improvement, lacking specific direct treatment methods. So far, the drug treatment effect of ARDS at home and abroad is not satisfactory. Therefore, it has become an urgent task to find a new treatment strategy to alleviate ARDS. Neutrophil elastase inhibitors can reversibly and competitively inhibit the release of neutrophil elastase, inhibit the activation of neutrophils and the infiltration of inflammatory cells in the lungs, alleviate the release of inflammatory mediators, and thus improve respiratory function, which has a good protective effect on various experimental ARDS. However, the efficacy of neutrophil elastase inhibitor represented by sivelestat sodium in the treatment of ARDS has reached a relatively consistent positive conclusion in animal experiments, while the results of clinical studies are different. These differences in clinical research still need further analysis, research and verification in clinical trials. At present, the clinical studies of neutrophil elastase inhibitors in the treatment of sepsis induced ARDS are very few, and there is a lack of related prospective randomized controlled clinical studies. Therefore, further prospective clinical trials are needed to evaluate the therapeutic effect of neutrophil elastase inhibitors on sepsis induced ARDS patients. This study is intended to determine whether neutrophil elastase inhibitor can reduce the mechanical ventilation time, Murray lung injury score, ICU hospitalization time and 28-day mortality of septic ARDS patients compared with the control group through a single center randomized controlled trial, so as to provide a new basis for the treatment strategy of septic ARDS patients.
Beta-lactam Intermittent Versus Continuous Infusion and Combination Antibiotic Therapy in Sepsis...

The study will be a prospective multicentre, randomized, open-label comparative continuous vs. intermittent pivotal βL (Beta Lactamine) antibiotic infusion strategies and combination vs. monotherapy trial conducted with a 2X2 factorial design.
Monitoring Mitophagy In Myeloid Cells Upon Intensive Care
SepticemiaSevere infections (sepsis) are a frequent cause of admission to the intensive care unit. Sepsis represent a significant risk for the health of patients in the short and medium term. Sepsis are notably linked to a change in the function of immune cells. In some patients, a state of pseudo-dormancy of monocyte and macrophage immune cells, called myeloid cell immunosuppression, is observed. This situation, which leads to a worsening of the infection, must be avoided because it represents a danger for the patient, even during antibiotic therapy. At present, these events are still very poorly understood. Research is needed to understand how the immunosuppression of myeloid cells occurs in order to adapt existing treatments or to find new ones. Laboratory work on animal models of sepsis has shown that this state of myeloid cell immunosuppression is closely linked to a modification of energy production by myeloid cells (monocytes and macrophages). The function of the mitochondria ("energy factory" of the cells) in these cells is impaired. Thus, restoring mitochondrial function in myeloid cells could be a therapeutic solution against the immunosuppression of myeloid cells during severe sepsis. The aim of this study is to verify whether alterations in mitochondrial function in myeloid cells occur in both patients with and without bacterial infection.
The Preeclampsia Registry
PreeclampsiaEclampsia3 moreThe purpose of The Preeclampsia Registry is to collect and store medical and other information from women who have been medically diagnosed with preeclampsia or a related hypertensive (high blood pressure) disorder of pregnancy such as eclampsia or HELLP syndrome, their family members, and women who have not had preeclampsia to serve as controls. Information from participants will be used for medical research to try to understand why preeclampsia occurs, how to predict it better, and to develop experimental clinical trials of new treatments.
Clinical Features and Outcomes of CBP Versus Non-CBP in Septic Children
SepsisChildren1 moreThe effect of continuous blood purification (CBP) in children is unclear. Also, the timing of early application is still being explored. In this study, we need to explore the efficacy and the timing of application of CBP in children with sepsis or septic shock.

Establishment of Early Diagnosis and Monitoring Model for Sepsis Patients
SepsisIn recent years, although the clinical treatment of sepsis has been greatly improved, it is still an important cause of death in ICU patients, and seriously threatens human health. Its predictive biomarkers have become one of the bottlenecks in the field of disease diagnosis, treatment and development of effective drugs to reduce incidence rate and mortality. This will eventually become the key point of treatment for patients with sepsis. In the early stage, the investigators have established a single center sepsis database and sepsis animal model, and made a preliminary exploration on the mechanism and treatment of sepsis. Based on the previous results, this study intends to create a national multi center sepsis apparent database and sample bank, collect the data of sepsis patients' injury characteristics, clinical characteristics, biochemical indicators, micro multidimensional and omics results, etiological characteristics, etc., and integrate them. Using big data combined with machine learning method, the early warning and real-time course monitoring model of traumatic sepsis is established. The completion of this project can achieve early warning of sepsis, real-time monitoring of the progress of the disease, early rational allocation of medical care, and reduce the mortality of sepsis patients.
nSeP: Detecting Neonatal Sepsis by Immune-Metabolic Network Analysis
SepsisDiagnosis of neonatal sepsis remains a challenge due to non-specific signs and diagnostic inaccuracies. Studies have shown that this could lead to overdiagnosis and overuse of antibiotic treatment, with potential long-term adverse effects. A systems approach towards diagnosing neonatal sepsis has been shown to have high accuracy in initial studies. This study aims to recruit a large validation cohort to confirm findings.
Population Pharmacokinetic Modeling to Optimize the Dosage of the Piperacillin / Tazobactam Combination...
Resuscitation Patients With SepsisPopulation pharmacokinetic modeling mathematically describes the pharmacokinetics of a drug and the variables likely to influence it in a "typical" patient population. We propose to model a Bayesian estimator, taking into account the individual factors that influence exposure to the piperacillin / tazobactam combination in a target population of sepsis, to allow for early assessment of serum Piperacillin / Tazobactam concentration profiles. optimization of dosing regimens. Indeed, pharmacokinetic tools of this type are already regularly successfully applied for other classes of antibiotics or immunosuppressants whose therapeutic index is narrow. They reduce the toxic risk and optimize the effectiveness of these treatments.
