Reduce susceptibility to cefiderocol in gram negative bacteria in children: Is hope already lost before it's even arrived?

Background: In last years the diffusion of carbapenem resistance in Gram-negative bacteria (CR-GNB) is increasing worldwide, mainly due to the expression of carbapenemases. Cefiderocol has molecular characteristics that ideally confers activity against all CR-GNB, but resistant strains have already been identified. We describe cefiderocol susceptibility profile among multi-drug resistant Gram-negative isolated from pediatric patients.

Clinical and Microbiological Characteristics of Deep Neck Abscesses in Pediatrics: Analysis of a Case Series from a 3rd Level Pediatric Hospital.

As there is currently no consensus on managing deep neck infections in pediatric populations, we report a case series from a large pediatric hospital. Clinical data of patients discharged from Istituto Gaslini-Children's Hospital from January 2014 to June 2020 with peritonsillar, parapharyngeal, or retropharyngeal abscess diagnoses were collected. A total of 59 patients were identified.

Epidemiology of Antibiotic Resistant Pathogens in Pediatric Urinary Tract Infections as a Tool to Develop a Prediction Model for Early Detection of Drug-Specific Resistance.

Antibiotic resistance is an increasing problem, especially in children with urinary tract infections. Rates of drug-specific resistant pathogens were reported, and an easy prediction model to guide the clinical decision-making process for antibiotic treatment was proposed. Data on microbiological isolation from urinoculture, between January 2007−December 2018 at Istituto Gaslini, Italy, in patients aged <19 years were extracted.

Early and Late Onset Neonatal Sepsis: Epidemiology and Effectiveness of Empirical Antibacterial Therapy in a III Level Neonatal Intensive Care Unit.

Unlabelled: Bloodstream infections play an important role in neonatal morbidity and mortality. In this study, we retrospectively analyzed etiology and antibiotic resistance profiles of bacteria isolated from blood or Cerebro Spinal Fluid (CSF) cultures to evaluate the appropriateness of initial empirical therapy of neonatal sepsis.

Methods: microbiological data from patients admitted to Neonatal Intensive Care Unit (NICU), from January 2005 to October 2018, were anonymously extracted from the Laboratory of Microbiology database.

Validation of the Giannella Risk Score for the Prediction of Infection by Carbapenemase-producing Enterobacteriaceae in the Pediatric Population.

Background: Despite efforts made to prevent the spread of multi-drug-resistant bacteria, carbapenemase-producing Enterobacteriaceae (CPE) has become one of the most dangerous threat worldwide. However, data on the epidemiology of CPE and on the correlation between CPE colonization and infection are scanty. The objectives of this study were first to describe the epidemiologic characteristics of colonizations and invasive CPE infections in the pediatric population, and second, to apply the Giannella Risk Score (GRS) to the pediatric population for the assessment of the risk of invasive CPE infection in patients with already known colonization.

In vitro activity of ceftaroline and ceftobiprole against methicillin-resistant Staphylococcus aureus with decreased susceptibility to vancomycin isolated in paediatric patients.

Minimal inhibitory concentrations (MIC, mg/l) of ceftaroline and ceftobiprole were evaluated over 70 methicillin-resistant Staphylococcus aureus (MRSA) strains with vancomycin MIC ≥1 isolated in a paediatric hospital. The proportion of non-wild-type strains (MIC > epidemiological cut off) was 18% for ceftobiprole and 64% for ceftaroline. Only 1.

The administration of a polyvalent mechanical bacterial lysate in elderly patients with COPD results in serological signs of an efficient immune response associated with a reduced number of acute episodes.

The administration of a polyvalent mechanical bacterial lysate (PMBL) in elderly patients with COPD has been shown to reduce the number of exacerbation. This is largely related to the involvement of cells belonging to the innate and the adaptive immune system (including dendritic cells, granulocytes, T and B lymphocytes and NK cells) that actively cooperate inducing the production of specific opsonizing antibodies directed to the antigens of PMBL. We have evaluated the production of antibodies directed to respiratory and systemic pathogens in a group of elderly COPD patients, recruited in a clinical trial, ancillary to a larger multicenter double blind, placebo-controlled, parallel-designed clinical trial in which patients were randomized to daily receive either PMBL or placebo.
