Evaluation of Reporting of Antibody-Drug Conjugate Associated Sepsis-related Toxicities
Sepsis (SMQ)Opportunistic Infections1 moreAlthough antibody-drug conjugate(ADC) has proved effective in treating many cancers, few patients receiving ADC may experience rare but life-threatening sepsis-related toxicities such as sepsis and septic shock. Today, data about sepsis/septic shock are scarce. The objective was to investigate reports of sepsis/septic shock adverse events related to ADC, including Gemtuzumab Ozogamicin, Trastuzumab Emtansine, Inotuzumab Ozogamicin, Enfortumab vedotin, Trastuzumab deruxtecan, Sacituzumab govitecan, Brentuximab Vedotin, Moxetumomab pasudotox, Polatuzumab Vedotin, Belantamab Mafodotin, loncastuximab tesirine and Tisotumab vedotin using international pharmacovigilance databases such as the FDA Adverse Event Reporting System (FAERS).
Diaphragm Ultrasound in Weaning From Mechanical Ventilation
Abdominal SepsisThis study aims to evaluate the efficacy of ultrasound derived variables in prediction of success of weaning from mechanical ventilation in critically ill patients with abdominal sepsis
Prognostic Interest of Leucocyte Immunophenotyping During the Acute Phase of Sepsis
Sepsis With Acute Organ DysfunctionSeptic shock is still a major cause of death in ICU. Sepsis diagnosis is linked with many clinical, hemodynamic and biological criteria which have a low sensitivity and specificity if they are considered separately. The extensive experimental data which have been published contrast with the hematological data collected by the physician at patient's bedside especially regarding neutrophils and platelets levels. When there is no obvious clinical sign, a biological tool reflecting the patient's immune status could be useful to understand the physiopathology of Sepsis and to predict the progression of the disease in the patient. On the long-term it could also help to define management strategies.

Impact of Specific Antimicrobials and MIC Values on the Outcome of Bloodstream Infections Due to...
Clinically Significant BacteremiaMain objective: to observationally assess the efficacy of different antimicrobials in Bloodstream Infection (BSI) due to Enterobacteriaceae producing ESBLs or carbapenemases. Specific objectives: Bacteraemic infections due to ESBL-producing Enterobacteriaceae: To demonstrate that β-lactam/β-lactam inhibitors are not associated with worse cure rate and mortality than carbapenems after controlling for confounders, both as empirical and definitive therapy. To demonstrate that fluoroquinolones as definitive therapy are not associated with worse cure rate and mortality than carbapenems after controlling for confounders. To demonstrate that empirical cephalosporins in monotherapy are associated with worse cure rate and mortality than carbapenems after controlling for confounders in infections others than urinary tract infections. To demonstrate that the association of active aminoglycosides with cephalosporins or fluoroquinolines is not associated with worse cure rate and mortality than carbapenems after controlling for confounders. To demonstrate that combination empirical and definitive therapy is not associated with better cure rate than monotherapy after controlling for confounders. For tigecycline, colistin, and fosfomycin, no hypothesis. The objective is to provide adjusted estimations of their association with outcome variables in comparison with carbapenem monotherapy according to clinical situation and infection. Bacteraemic infections due to carbapenemase-producing Enterobacteriaceae: To demonstrate that combination therapy is associated with worse cure rate and mortality than monotherapy after controlling for confounders. To show that carbapenems are associated with worse cure rate and mortality when used in infections other than urinary tract caused by isolates showing MIC <2 µg/mL for imipenem or meropenem in comparison to those caused by isolates with higher MIC, after controlling for confounders. To show that colistin used at a dose >6 million IU per day is associated with improved outcomes in comparison with lower dose, after controlling for confounders.
Impact of Rapid Pathogen Identification From Blood Cultures (RABbIT)
BacteremiaSepsis2 moreSeptic shock carries high mortality, which may be exacerbated by inappropriate initial therapy. Inappropriate therapy may result from unanticipated antimicrobial resistance. Conversely, positive blood cultures may result from contamination, leading to unnecessary therapy and procedures and possibly prolonged hospitalization. Clinicians may also resort to broad spectrum antimicrobials and be hesitant to de-escalate while awaiting susceptibility results. The investigators hypothesize that rapid identification of pathogens and antimicrobial resistance will ameliorate the above problems and improve time to optimal therapy, avoid unnecessary therapy and ultimately improve patient outcomes. While there are a number of in-vitro and uncontrolled clinical studies, there is a paucity of well-designed clinical trials objectively examining the real-world clinical and health-economic impact of such technology. To date only one randomised trial has been performed in the US (ClinicalTrials.gov NCT01898208), at a setting with low endemic rates of antimicrobial resistance. This is a companion study to NCT01898208. The investigators aim to study the clinical impact and cost-effectiveness of a strategy for rapid pathogen and resistance detection in a setting with a moderate to high levels of antimicrobial resistance.
Antibiotic Administration and Blood Culture Positivity in Severe Sepsis and Septic Shock
Severe SepsisSeptic Shock1 moreSepsis is a significant cause health care expenditure and carries an extremely high rate of morbidity and mortality if not treated appropriately. From 1979 to 2000, sepsis resulted in over 10 million admissions to hospital in the United States with a mortality rate of 17.9 to 27.8 percent. In Canada, it is estimated that the incidence of sepsis from 2008-2009 was 103.3 per 100,000 per year. Advances in the multifaceted management of sepsis in recent years have resulted in improved clinical outcomes. However, the cornerstone of sepsis management relies on the prompt administration of appropriate antibiotics. Current clinical practice suggests that antibiotic administration can be delayed up to 45 minutes in order to obtain blood cultures, whose results have a profound impact on the type and duration of antimicrobial therapy. Unfortunately, this recommendation is based on very little evidence and the investigators have found that potential life-saving treatment is often delayed in order to abide by it. Furthermore, recent data suggest that mortality could be increased by approximately 5% by delaying antibiotic administration for that time period. The investigators therefore wish to organize a prospective, multi-centre trial in order to identify the effect of antibiotic administration on blood culture positivity in patients presenting with severe sepsis or septic shock. Other objectives will be to elucidate which patient factors, including age, co-morbid conditions and clinical presentation, as well as antibiotic choice will affect blood culture results. This study will be conducted in the emergency departments at St. Paul's Hospital (SPH), Vancouver General Hospital (VGH), Lion's Gate Hospital (LGH), Surrey Memorial Hospital, Montreal General Hospital (MGH), Royal Victoria Hospital (RVH) and Maricopa Integrated Health System. Patients identified for the aforementioned conditions will be treated as per routine hospital protocol. If the patient is deemed eligible for the study, a second set of blood of blood cultures will subsequently be drawn ideally between 30 and 60 minutes after the administration of antibiotic therapy. Subject demographic data will be collected pertaining to age, comorbid immunocompromised conditions, vital signs, laboratory tests pertaining to end organ dysfunction, suspected source of sepsis, the type antibiotics administered and the timing of antimicrobial administration with respect to the second set of blood cultures taken. Our hypothesis is that blood culture positivity in patients presenting with severe sepsis and septic shock will not be altered significantly by antibiotic therapy. If so, our study would strongly argue against delaying life-saving therapy and would thus greatly improve patient care in our local emergency rooms. If incorrect, our study would be the first to demonstrate the benefit of obtaining blood cultures before antibiotic therapy and would strengthen current recommendations.
Microcirculatory Changes During Magnesium Sulphate Infusion in Sepsis
Severe SepsisSeptic ShockDuring infections (sepsis) bloodflow in small vessels (microcirculation) becomes disturbed. Restoration of bloodpressure and cardiac performance may not be sufficient to correct these alterations. Magnesium is a potent vasodilator which may be used to open up the small vessels, in order to reduce organ failure.
The Application of Soluble Triggering Receptor Expressed on Myeloid Cells-1 in Sepsis & Relevant...
SIRSSepsisTriggering receptor expressed on myeloid cells-1 is a member of the immunoglobulin superfamily of receptors that is specifically expressed on the surfaces of monocytes and neutrophils.TREM-1 expression is increased in infectious diseases and is associated with the release of soluble TREM-1 (sTREM-1).There has been demonstrated that the value of plasma sTREM-1 levels as an indicator of sepsis was superior, although other studies reported that the value of sTREM-1 for diagnosing sepsis was inferior.An increasing number of studies indicate that there are increased levels of sTREM-1 in body fluid samples for the following diseases and conditions: sepsis, pneumonia, pleural effusion, septic arthritis, meningitis, peritonitis, and uterine cavity infection. Inflammation is now believed to play a major role in the pathophysiology of AKI. It is hypothesized that the initial insult results in morphological and/or functional changes in vascular endothelial cells and/or in tubular epithelium in sepsis models. Then, leukocytes including neutrophils, macrophages, natural killer cells, and lymphocytes infiltrate into the injured kidneys and induce the generation of inflammatory mediators. Whether urine sTREM-1 could also be detected and its significance in sepsis and AKI has not been reported yet. The present study focused on the value of serum & urine sTREM-1 for sepsis identification, severity and prognosis assessments, and potential sepsis-related AKI. We also made comparisons between sTREM-1 and WBC counts, serum CRP, serum PCT, urine output,CC SCr, and BUN among sepsis patients.
Pharmacokinetics of Understudied Drugs Administered to Children Per Standard of Care
AdenovirusAnesthesia57 moreUnderstudied drugs will be administered to children per standard of care as prescribed by their treating caregiver and only biological sample collection during the time of drug administration will be involved. A total of approximately 7000 children aged <21 years who are receiving these drugs for standard of care will be enrolled and will be followed for up a maximum of 90 days. The goal of this study is to characterize the pharmacokinetics of understudied drugs for which specific dosing recommendations and safety data are lacking. The prescribing of drugs to children will not be part of this protocol. Taking advantage of procedures done as part of routine medical care (i.e. blood draws) this study will serve as a tool to better understand drug exposure in children receiving these drugs per standard of care. The data collected through this initiative will also provide valuable pharmacokinetic and dosing information of drugs in different pediatric age groups as well as special pediatric populations (i.e. obese).
