After birth, in the presence of risk factors for early neonatal bacterial infection (IBNP), the pediatrician must make a difficult decision quickly or not to prescribe additional examinations and / or hospitalize or not the newborn in order to administer parenteral antibiotics. This decision takes into account several contextual data, (clinical, biological and bacteriological clinical data) to be considered simultaneously. These information lack sensitivity and specificity. Therefore, the common attitude among newborns in many countries remains the achievement of a significant number of additional tests and the establishment, without a prior evidence of infection, intravenous empirical antibiotic therapy for 48 -72h at least in hospitalization. However, the diagnosis of IBNP posteriori, is often reversed. This attitude is: 1. one source to higher health care costs (hospitalization, additional examinations) 2. Selection of the bacterial ecology of the newborn and neonatal services and 3. stress for the newborn and parents
This study is divided in 2 parts. Part 1a is being conducted to evaluate the safety, tolerability, and relative bioavailability of the 2 free base tablet formulations (roller compacted [RC] and high shear wet granulation [HSWG]) compared to the reference capsule formulation under fasted conditions. This is a 3-period; cross-over study that will guide which gepotidacin formulation will be used for future studies. Following review of pharmacokinetic (PK) and safety data in Part 1a, a decision will be made whether to proceed with Parts 1b and 2. Part 1b is a 2-period, cross-over study and will assess the effect of food on the PK of the selected gepotidacin tablet formulation from Part 1a. In Part 2, the PK of the selected gepotidacin tablet formulation from Part 1a in Japanese (2a) and Chinese (2b) subjects will be evaluated under fasted conditions. The duration of the study (from Screening to the Follow-up visit) will be approximately 44 days (Part 1a), 41 days (Part 1b) and 38 days (Part 2a and 2b each), respectively. The approximate number of subjects enrolled in Part 1a will be 27 (9 subjects in each of the 3 treatment sequences), 16 in Part 1b (8 subjects in each of the 2 treatment sequences) and 12 Japanese and 12 Chinese subjects in Part 2a and 2b, respectively.
Main objective: to observationally assess the efficacy and safety of different antimicrobials in BSI due to ESBL or carbapenemase-producing Enterobacterales in SOT. Secondary objectives: 1. To evaluate the efficacy and safety of different antibiotics used for the treatment of infections caused by ESBL- and carbapenemase-producing Enterobacterales in the SOT population. 2. To compare the efficacy of different antimicrobials between SOT and non-SOT patients (using matched controls from the "non-transplant" INCREMENT cohort). 3. To create a microbiological collection of ESBL- and carbapenemase-producing Enterobacterales isolated from the SOT population. 4. To provide data on specific MICs for each antimicrobial evaluated. 5. To provide data on the prevalence of specific mechanisms of resistance and their clinical impact in the particular setting of SOT. 6. To organise an international consortium capable of developing high quality prospective cohort studies and randomised clinical trials in the area of MDR and XDR Enterobacterales in SOT.
The "gold standard" for diagnosing a bacterial infection is isolation of the pathogenic germ, which is not easy in routine clinical practice. Conventional markers do not have sufficient diagnostic value for making a rapid diagnosis on admission. A 2004 literature calculated the diagnostic values of C-reactive protein (CRP) and procalcitonin (PCT) levels for the diagnosis of bacterial infections, relative to other causes of inflammation. For CRP, the sensitivity was 75% (95% CI: 62%-84%) and the specificity was 67% (95% CI: 56%-77%). For PCT, the sensitivity was 88% (95% CI: 62%-84%) and the specificity was 81% (95% CI: 67%-90%). The first cellular immune response to infection consists of the mobilization of polynuclear neutrophils from the bone marrow to the infection site under the effect of pre-inflammatory cytokines, as well as the apoptosis of lymphocytes and their sequestration at the infection site. This results in lymphopenia and the elevated polynuclear neutrophil count (PNN) observed in bacterial infections. Hence, it is legitimate to hypothesize that the neutrophil to lymphocyte ratio (NLR) can be used in the diagnosis of bacterial infection. This ratio's value in the diagnosis of sepsis in the emergency department was studied and the researchers found higher diagnostic values than for CRP and PCT. The NLR's potential value in the diagnosis of a bacterial infection in a context of fever or hyperthermia (regardless of the presence or absence of bacteraemia) has not been studied before. This ratio could also be compared with standard biomarkers (CRP and PCT levels, the white blood cell count and the PNN).
Antimicrobial stewardship program (ASP) is recommended to improve appropriate antimicrobial use, reduce bacterial resistance, unnecessary drug costs and enhance patient health outcomes. Two core strategies of ASP recommended as effective in guidelines are formulary restriction with drug preauthorization and prospective audit with feedback. Investigators will evaluate the effectiveness of the 2 strategies using antimicrobial utilization and patient outcomes.
To determine the safety and descriptive efficacy of dalbavancin for the treatment of acute bacterial skin and skin structure infections in children, aged birth to 17 years (inclusive), known or suspected to be caused by susceptible Gram-positive organisms, including methicillin-resistant strains of Staphylococcus aureus.
This research will test a new ultra-rapid technology (called ID/AST Accelerate system) that uses a digital microscope to identify bacteria based on their growth patterns. This method does not have to wait for bacteria to grow in a lab. The new method can identify the type of bacteria within 2 hours of receiving a specimen. The new method also shows the effect of selected antibiotics on the bacteria including multidrug resistant bacteria so that doctors know within 6 hours from specimen collection which antibiotic kills the bacteria. To check the accuracy, speed and impact of the new method on antibiotic prescribing, investigators are proposing a study with two parts; The first part will test the accuracy and speed of the results obtained by the new method. The second part will test if having the results from the new method early would change the antibiotics prescribed to a patient in a simulation experiment. An independent infectious disease physician will be shown the results from the new method and asked if the results were accurate, would it change the antibiotic treatment for the patient.
- NSAIDs are widely consumed, and some are currently available for self-medication with indications 'Pain and Fever' (Cavalié, National Agency for Drug Safety (ANSM), 2014) - There is no recommendation to limit their use in bacterial infections except for chicken pox in children. - To date, no study has highlighted the aggravating role of exposure to NSAIDs on bacterial infections in adults, based on the usual septic severity Levy's score (SSS), and mortality, but it delays adequate antibiotics (Legras, Critical Care, 2009) - Community-acquired bacterial infections in adults exposed to NSAIDs are serious by their spread (multiple locations), and suppurative character requiring frequent use of invasive procedures such as surgery or drainage. The SSS does not reflect the seriousness of these infections. They are frequently associated with use of ibuprofen (63.4%), and self-medication practices (65.5%). The main hypothesis is that NSAIDs exposure is associated with a specific severity of community-acquired bacterial infection, marked by dissemination, suppurative complications or even invasive procedures requirement. Our objectives are also to: - Describe what NSAID use terms are associated to the risk of serious bacterial infections: molecule, dosage, duration of exposure, access (prescription or self-medication), associated drugs. - To determine what type (s) (s) of bacterial infection is worsened by exposure to NSAIDs. - To determine if other risk factors contribute to severity of bacterial community acquired infection - To describe hospital costs associated to such severity of bacterial infection
This is a study of up to 275 participants from birth to 12 months who are having a chest x-ray while a patient at the Queen Elizabeth Central Hospital in Blantyre, Malawi. Participants will have thermal pictures of their chest taken by trained study staff using a Smartphone and a FLIR ONE attachment. Thermal images will be read by trained study staff to determine if bacterial pneumonia is present. Results of the thermal images will then be compared to the results of the chest X-ray. If additional images of the chest are available, additional thermal images will be taken of the same location within 24 hours of the other image.
