Background And Objectives: Antimicrobial stewardship programmes (ASPs) have resulted in antimicrobial consumption (AMC) reduction and quality of prescription (QOP) improvement. However, evidence of ASP impact in paediatrics is still limited. This study aims to assess a paediatric ASP long-term outcomes.

Antimicrobial stewardship programs (ASPs) optimize antimicrobial use, improve patient outcomes, and reduce resistance. To assess the effectiveness of ASPs, it is necessary to have indicators that can be widely used. Defined daily dose (DDD) was designed by WHO for the adult population as a consumption indicator.

Introduction: Paediatric infective endocarditis (IE) is a serious condition associated with significant mortality. Information in Spain is limited and comes from case series from single centres. The aim was to describe the epidemiology, clinical features, microbiology and outcome of paediatric IE in Andalusia.

Article Synopsis
  • Antimicrobial resistance is rising as a major public health issue, with irrational use of antimicrobials being a key contributor, particularly among children who often receive inappropriate prescriptions.
  • The implementation of antimicrobial stewardship programmes (ASPs) is critical in fighting this resistance and should be tailored specifically for paediatric patients due to their unique needs compared to adults.
  • The Sociedad Española de Infectología Pediátrica (SEIP) aims to promote and provide resources for effective paediatric ASPs in Spanish hospitals to enhance patient care and combat antimicrobial resistance effectively.

Unlabelled: The presence of active viral infections has an impact on the prognosis of patients undergoing hematopoietic stem cell transplantation (HSCT). Nevertheless, the number of reports of cytomegalovirus infection in patients with inborn errors of immunity (IEI) who undergo HSCT is relatively low. To analyze the effect of cytomegalovirus infection acquired prior to curative treatment on patient survival in 123 children with IEI.

Vancomycin is used to treat a wide variety of infections within the pediatric population. In adults, continuous infusion of vancomycin (CIV) has been evaluated as an alternative to intermittent infusion of vancomycin (IIV) with potential advantages. In children, the use of CIV is increasing; however, data is currently limited.

Background: Data on SARS-CoV-2 transmission among children living with healthcare workers (HCWs) are scarce.

Methods: A cross-sectional study was performed at a tertiary Hospital in Madrid, including children of HCW who suffered from SARS-CoV-2 infection between March and May 2020. Children underwent enzyme-linked immunosorbent serological study for detecting SARS-CoV-2 antibodies: VIRCELL IgG assay.

Background: Visceral leishmaniasis (VL) is an endemic in Southern Europe. However, details regarding disease burden, clinical presentations, laboratory markers, management and outcome in children are scarce.

Methods: Medical records of children (<14 years) admitted with VL to 10 pediatric units in Andalusia (2004-2019) were retrospectively reviewed.

Primary immunodeficiencies (PIDs) are rare, undiagnosed and potentially fatal diseases. Clinical manifestations of PID can be fatal or leave sequelae that worsen the quality of life of patients. Traditionally, the treatment of PIDs has been largely supportive, with the exception of bone marrow transplantation and, more recently, gene therapy.

Objective: Few data exist regarding the impact of antimicrobial stewardship programs on antifungal use. We evaluated the efficacy and safety of a comprehensive long-term antimicrobial stewardship program (ASP) focused on antifungal use.

Methods: During a 9-year period, we quarterly assessed antifungal consumption, incidence density of hospital-acquired candidemia, Candida spp.

A progressive increase in the incidence of infections caused by multidrug-resistant microorganisms is being reported. Among these resistant microorganisms, the main threats are extended-spectrum β-lactamase-, AmpC-, and carbapenemase-producing Gram-negative bacilli, methicillin-resistant Staphylococcus aureus and vancomycin-resistant Enterococcus faecium. To address this important problem, it is essential to establish pediatric Antimicrobial Stewardship programs, perform active epidemiological surveillance and develop an adequate infection control policy.

Article Synopsis
  • The study evaluated the effectiveness of using rt-PCR to detect cytomegalovirus (CMV) DNA in dried blood spots from newborns for diagnosing congenital CMV infection in Spain.
  • Out of 103 patients with confirmed cCMV and 81 controls, the rt-PCR method showed a sensitivity of only 56%, indicating it missed many cases, especially those with lower viral loads at birth.
  • Despite its high specificity (98%), the findings suggest that a negative rt-PCR result cannot confirm the absence of cCMV infection, particularly in newborns with lower initial viral levels.

Article Synopsis
  • The study evaluated antimicrobial use in hospitalized children to identify improvement areas for prescribing practices.
  • A total of 171 pediatric patients were analyzed, with a prevalence of antimicrobial prescriptions at 49.7% and an appropriateness rate of 60.9%.
  • Common misuses included prolonged prescriptions and using broad-spectrum agents unnecessarily, highlighting the need for better antimicrobial stewardship in the hospital.
