Active clinical trials for "Pneumonia, Staphylococcal"

Study design: Allocation: Randomized Endpoint classification: Efficacy study Masking: Open label Primary purpose: Treatment Primary endpoint: Incidence of reaching the target serum trough concentration Secondary endpoint: Clinical efficiency, Antibiotic use, acute kidney injury.

The purpose of this study is the prevention of Staphylococcus aureus pneumonia in mechanically ventilated subjects heavily colonized with S. aureus. Staphylococcus aureus is a human pathogenic bacterium that causes severe infections, including pneumonia and sepsis. Hospital-acquired bacterial pneumonia (HABP) caused by S. aureus, including ventilator-associated bacterial pneumonia (VABP) in mechanically ventilated subjects, is a significant public health threat despite efforts to optimize antibiotic treatment. ASN100 is an investigational monoclonal antibody product that targets the toxins produced by S. aureus to protect subjects from developing S. aureus pneumonia.

The objectives of this study are to assess the safety, tolerability, pharmacokinetics, pharmacodynamics and clinical outcome of patients who have severe pneumonia caused by Staphylococcus aureus (S. aureus) after a single intravenous administration of KBSA301 in addition of standard of care antibiotic treatment.

The purpose of this study is to determine whether aerosolized vancomycin is effective in the treatment of methicillin-resistant staphylococcus aureus pneumonia under mechanical ventilation.

Clinical trial looking at safety and efficacy of MEDI4893 in prevention of pneumonia caused by Staphylococcus aureus in high-risk patients

Staphylococcus aureus expresses a variety of virulence factors, including Panton Valentine leukocidin (PVL), a cytotoxin. PVL is specifically associated with primary skin and soft-tissue infections and severe necrotizing pneumonia (Gillet et al. Lancet, 2002;359:753-9). PVL-positive S. aureus pneumonia is often preceded by influenza-like symptoms, and is mainly characterized by hemoptysis, pleural effusion, rapid onset of acute respiratory distress, leukopenia and a high fatality rate (65%) (Gillet et al. Lancet, 2002;359:753-9). Ten year after the first description of this disease and a number of controversies in the scientific literature, the question arise as to whether PVL remains an independent factor of severity in S.aureus pneumonia. In addition, numerous questions remain unanswered yet; these are: (i) which factors, including treatment regimen, are associated with favourable outcome?, (ii) what is the susceptibility toward antibiotics of strains associated with this disease ? (iii) is there any genetic susceptibility of the host to explain both the rarity, and the explosive presentation of the disease ? To address the above questions a prospective observational study at the nationwide level will be set up. All French hospitals will be invited to describe the clinical features of all new cases of S. aureus community-acquired pneumonia with severity criteria, regardless PVL production. The study will include an investigation of a possible innate immune dysfunction in collaboration with the INSERM-U550 (Génétique Humaine des Maladies Infectieuses, Faculté Necker, Paris). Hence, in addition to collecting clinical and biological data from all pneumonia cases as well as all strains of S. aureus isolated, the patients with PVL-positive pneumonia will be sampled for immune genetic studies (ORFeome sequencing and functional studied)

Recently, the investigators described a new mucoid phenotype of Staphylococcus aureus cultured from the airways of cystic fibrosis (CF) patients.In this observational study, the investigators plan to determine the prevalence of mucoid S. aureus in respiratory specimens of CF patients and a possible impact of mucoid S. aureus on lung disease severity.

Secondary bacterial influenza pneumonia caused by Panton-Valentine Leukocidin Positive Staphylococcus aureus is a rare complication but with poor prognosis. This pathology seems to affect young patients (20-40 years) without any medical history. Since the influenza pandemic of 2009, this complication is more and more mentioned, sought and diagnosed. However, the literature is poor, consisting of case reports, experimental studies on murine models, and low-power studies. The main objective is to evaluate the mortality in intensive care units of patients post-influenza bacterial pneumonia due to a Panton-Valentine Leukocidin positive Staphylococcus aureus
