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.
The Outpatient Parenteral Antibiotic Therapy (OPAT) service consists of providing antimicrobial therapy through parenteral infusion without hospitalization. This service is provided to stable patients otherwise ready for hospital discharge. Generally, the clinical monitoring for this patient population is minimal. However, clinical monitoring of vancomycin, an antibiotic widely used during OPAT, can be intensive primarily due to therapeutic drug monitoring. To ensure optimal treatment and minimize nephrotoxicity and microbial resistance, TDM and monitoring of serum creatinine levels are crucial during vancomycin therapy. TDM of vancomycin with OPAT presents a challenge for patients who must frequently travel to blood sampling facilities or the hospital for measurements. An alternative sampling method for TDM is the dried blood spot (DBS) method, which involves collecting a small drop of capillary blood from a finger prick onto filter paper. By implementing the DBS sampling method, the amount of outpatient visits regarding vancomycin treatment in OPAT can be reduced. Furthermore, the addition of measuring a biochemical parameter, such as renal function with serum creatinine, could lead to even less outpatient visits during OPAT. To date, studies investigating the effectiveness of DBS sampling of vancomycin and creatinine in terms of reducing outpatient visits have not yet been conducted in the OPAT population.
Severe bacterial infections are a worldwide scourge. However, the epidemiology of this type of infection varies over time. It is therefore essential to monitor them in order to prevent them more effectively. At this time, in France, no monitoring exists for this kind of infections.
The goal of this observational study is to investigate how bacterial populations from the intestine and mouth of patients change during the hospitalization period and evaluate if some populations of specific bacteria increase or decrease the risk of acquiring an infection or becoming colonized by pathogenic bacteria. Participants will have the following samples collected during enrollment: stool samples (maximum 2x/week), blood draws (1x/week), oral swab (1x/week).
