Preventing the spread of multidrug-resistant bacteria (MRB) is a major challenge for hospitals today. MRB are defined as bacteria that combine several resistance mechanisms to different families of antibiotics, thus limiting therapeutic possibilities in the event of infection. The spread of MRBs is particularly prevalent in hospital units caring for fragile patients, such as neonatal units. Preventing the spread of MRBs is of prime importance in these units, in order to limit the number of infections caused by these germs. Newborns are at risk of infection due to intrinsic factors such as an immature immune system and fragile skin, as well as extrinsic factors such as mechanical ventilation and intravascular catheters. In Germany, a 2012 KRINKO agreement encourages neonatal units to monitor MRB carriage on a weekly basis. This measure enables early detection of MRB colonization outbreaks in neonatal units. In France, MRB carriage monitoring in neonatal units is not systematic. Spore-forming bacteria also require close monitoring in neonatology, as they do not strictly meet the definition of MRB, but represent a major threat to newborns. The main spore-forming bacterium of medical interest is Bacillus cereus (BC), which is responsible for serious infections in premature infants. BC is resistant to the use of hydro-alcoholic solutions. The origin of these BC infections remains controversial, with numerous studies in the international literature suggesting a link between BC infections and contamination of breast milk given to infants in neonatal units. The role of environmental contamination has also been studied. The potential seriousness of these BC infections justifies the systematic detection of the carriage of this spore-forming bacterium in routine coprocultures, in the same way as other MRB germs. In the neonatal unit at Hôpital de la Croix Rousse, MRB and BC are routinely tested on patient arrival, and then weekly until discharge. If MRB or BC germs are found in children's stools reinforced specific hygiene measures are implemented to prevent cross-transmission in this open-bay unit with little space between incubators. Reinforced specific hygiene measures represent a time constraint for the nursing team, for parents and a financial burden for the neonatal unit. However, to our knowledge, there are no international or national recommendations concerning the duration of stools reinforced specific hygiene measures. Our clinical experience has shown that the persistence of pathogenic germs in stools seems to vary in duration depending on the microorganism. To better determine the optimal duration of reinforced specific hygiene measures, as it is costly in terms of work time, parental stress, and hospital expenses due to reinforced hygiene conditions during the isolation period.
The purpose of the pivotal study is to collect blood specimens and clinical data from pediatric (>90 days old) and adult (≥18 years old) patients presenting with signs and symptoms suggestive of acute bacterial or viral infection. These samples will be used to establish the diagnostic performance of MeMed BV™ for differentiating bacterial from viral infection using method comparison and/or method concordance.
The investigators use Gram-stained specimens provided from clinical settings to develop and evaluate the accuracy of Gram staining analysis AI
Recently, it has been seen that investigations from saliva samples could be an alternative to those from blood samples. Saliva collection is a simple, non-invasive, cost-effective, and relatively easy method, making it potentially suitable as a new diagnostic tool in pediatric patients. In the current literature, elevated levels of saliva CRP, TNF-α, IL-6, and IFN-γ have been reported in inflammatory conditions. However, while there are animal studies suggesting the use of saliva PCT levels for focal diseases such as gingival inflammation and periodontitis and as a potential tool for non-invasive detection of sepsis, there is no human study regarding its use in systemic infections. The aim of this study is to evaluate the correlation between serum PCT levels and saliva PCT levels in children suspected of SBE and to determine the diagnostic value of saliva PCT.
Streptococcus pneumoniae (pneumococcus), Neisseria meningitidis (meningococcus), and Haemophilus influenzae (hemophilus) are among the main bacteria responsible for invasive bacterial diseases (MBIs) that result in severe clinical pictures also characterized by a high frequency of serious complications. Surveillance of infections caused by these pathogens and their distribution by serotypes/serogroups is essential to guide public health interventions, assess epidemiologic trends, monitor any secondary cases, estimate the proportion of preventable cases, identify any vaccine failures, and evaluate the impact of vaccine strategies.The present study aims to study the epidemiology of invasive bacterial diseases, characterize the circulating strains also in order to plan treatment and prevention strategies.
Vaccine-preventable disease (VPD) surveillance should be a priority throughout the world. In Italy, however, there is limited attention to the epidemiology of VPDs, with the consequence that their incidence is largely underestimated. Although notification of vaccine-preventable diseases is mandatory, very often the etiologic agents causing VPDs are not identified the etiological agents causing the major and most severe infectious diseases in childhood. Several reasons underlie the underestimation. For example, not having a good surveillance system does not allow us to organize a sustainable prevention project for example based on on the introduction of new vaccinations. For example the limited use of low-cost high-sensitivity techniques such as real-time PCR, which could, if more widely used, improve pathogen identification with 3 times the sensitivity of standard cultural methods. Therefore, the idea of this multicenter, biological sample study is to take advantage of the regional pediatric network with the goal of improving VPD surveillance and increase awareness of the importance of surveillance of preventable diseases with the vaccine within the pediatric network.
This is an experimental study without drug and device, non-profit, on biological samples stored at the Tropica Biobank of the DITM. The aim of the project is to verify the performance of NGS-based assays, which can be used in the field of microbiology. The clinical evaluation investigations of NGS technology will be conducted on an adequate number of clinical blood samples and rectal swabs. The analyzes will be compared with the standard microbiology methods used in the DITM diagnostic routine.
DUOFAG® is a phage cocktail containing bacteriophages active against Staphylococcus aureus and Pseudomonas aeruginosa. It is an investigational medicinal product for the treatment of surgical site infections caused by S. aureus and P. aeruginosa. The primary objective of the study is to demonstrate the safety of DUOFAG® and the clinical and microbiological change within 10 weeks after the start of treatment or until healing.
Experimental study without drug and device, on pseudo-anonymized samples archived at the Tropica Biobank. The objective is to evaluate the performance for the identification of microorganisms in blood samples and rectal swabs of real time PCR assays for the targets: KPC, VIM, IMP, NDM, Acinetobacter OXA, Oxa48, MCR. The evaluations will be carried out taking into consideration the data obtained from the diagnostic routine at the DITM.
