Filter by:This feasibility and safety pilot study looks to determine whether transferring a parents healthy, diverse nasal microbiota to the participant's infant(s) will create a healthy, diverse neonatal nasal microbiome.
Clinical trial looking at safety and efficacy of suvratoxumab in prevention of pneumonia caused by Staphylococcus aureus in high-risk patients
Phase 1b/2a, Randomized, Double-Blind, Placebo-Controlled, Multiple Ascending Dose Escalation Study of the Safety, Tolerability, and Efficacy of Intravenous AP SA02 as an Adjunct to Best Available Antibiotic Therapy Compared to Best Available Antibiotic Therapy Alone for the Treatment of Adults With Bacteremia Due to Staphylococcus aureus
Hypothesis: The investigators hypothesize that in patients with CRSwNP who demonstrate sinus colonization with staphylococcus aureus, the administration of dupilumab will be associated with decreased staph colonization and an increase in microbial diversity. Primary Objective will be to demonstrate that dupilumab reduces staphylococcus aureus (phyla firmicutes) abundance while increasing microbial diversity in patients with CRSwNPs who are culture positive for staph aureus at enrollment. Secondary Objectives will be to correlate reduction in Staph aureus abundance and improved bacterial diversity with increased expression of anti-microbial proteins (ß-defensins1-4) and cathelicidin LL-37. In addition, the investigators will correlate improvements in microbial diversity/decreased staph abundance with clinical improvements as assessed via questionnaires and objective/subjective smell function and also as improvements in cellular/immune T2 inflammation as assessed by reduced expression of T2 cytokines/chemokines and eosinophil/eosinophil-derived proteins.
Two commonly used treatments for latent tuberculosis infection are either 4 months rifampicin or 6-9 months isoniazid. The invistigators will study the risk of acquisition of rifampicin resistance in commensal Staphylococcus aureus in persons treated with rifampicin versus in persons treated with isoniazide. Through repeated swab cultures before, during, and after treatment the investigators will also investigate potential accumulation of mutations associated with rifampicin resistance over time. Finally, household contacts to persons with rifampicin-resistant S. aureus will be examined to investigate whether onward transmission of rifampicin-resistant S. aureus occurs within households.
Atopic dermatitis (AD) is the most common chronic inflammatory skin disease. Clinical studies have demonstrated a link between staphylococcal skin colonization and the pathogenesis of AD, but the implication of bacterial virulence factors remains largely uncharacterized. Finally, AD is often associated with herpes simplex skin infections. The aim of this project is to investigate the role of staphylococcal toxins in the exacerbation and maintenance of atopic skin inflammation and in the occurrence of infectious complications such as eczema herpeticum.
The number of arthroplasties is expected to grow in the next few years. Staphylococcus aureus (SA) is a primary cause of prosthetic joint infection (PJI) with serious consequences. This microorganism is frequently associated with treatment failure, hospitalizations and need of prosthesis removal, leading to an important morbidity and an increase in healthcare costs. ARTHR-IS is a retrospective multi-center study which aims to estimate the burden of SA-PJI after a hip or knee arthroplasty and their risk factors. Other objectives are to quantify the costs, the number of hospitalizations and the surgical procedures needed to treat and control the infection and finally the factors influencing therapeutic failure. Through a case-control design, ARTHR-IS will group 20 hospitals across 5 European countries in order to include 150 cases and 450 controls. The results of this study will provide critical information to develop strategies to prevent and treat SA-PJI and reduce treatment failures. Also, the results from ARTH-IS study will help in the design of future clinical trials in prosthesis infections by providing reliable estimates on the incidence of SA-PJI and the subsequent burden on health care services.
The aim of this study is to determine if delta-haemolysin production deficiency of Staphylococcus aureus is a marker in favour of chronic infections on implants
S. aureus bloodstream infection (SAB) is a severe disease associated with a 30% case-fatality rate at 12 weeks. Severity of this disease is related to the high prevalence of staphylococcal Deep Foci of Infection (SA-DFI), which require prolonged duration of antimicrobial therapy and specific treatment. Timely diagnosis and management of SA-DFI is associated with an improvement of prognosis during SAB. 18 FDG PET/CT (PET/CT) is a useful tool in the diagnosis of infectious foci during bacterial infections. An ecological study performed in the Netherlands has shown that use of PET/CT in patients with Gram positive cocci bloodstream infection was associated with an increase of detection of DFI and a decrease of recurrences and mortality compared to historical controls. The investigators hypothesize that SAB poor prognosis is in part related to the lack of diagnosis of all infectious foci and consequently to a suboptimal treatment.
The study EPICS-6 consists of three study phases. Emergency Department patients are screened for nasal and pharyngeal colonisation with Methicillin sensitive and Methicillin resistant Staphylococcus aureus (MSSA/MRSA) using a point-of-care (POC)-PCR-testing method (cobas®LIAT®-System, Roche Molecular Systems Inc.) The first aim of this study is to describe the prevalence of MSSA/MRSA-colonisation in a routine cohort of Emergency Department patients. The second aim is to determine the impact of POC-guided decolonisation as compared to conventional laboratory testing on in-hospital infection rates with MSSA/MRSA in a pre-post-comparison study.
