For many years, biotics (including probiotics, prebiotics, human identical milk oligosaccharides, synbiotics, and postbiotics) have been added to infant formula to influence the gut microbiota of formula-fed infants, aiming to bring it closer to that of breastfed infants. The Special Interest Group on Gut Microbiota and Modifications (SIG-GMM) of the European Society for Paediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN) evaluated clinical outcomes from studies on biotic-supplemented infant formulas. A modified Delphi process was used to establish consensus on recommendations.

A previous study settled in the Campania Region (Southern Italy) has proven the effectiveness of a multifaceted antimicrobial stewardship program in reducing prescription rates and use of broad-spectrum molecules in the Primary Care setting. Since autumn 2022, the amoxicillin shortage has been reported at a national level, and respiratory pathogens resurged in children after the easing of COVID-19 pandemic restrictions. We aimed to assess the impact of amoxicillin shortage on antimicrobial prescription patterns and quality indexes in the same setting as the past AMS campaign.

Article Synopsis
  • Acute myocarditis cases in kids are increasing in Italy, with 65 suspected cases reported in 2024, largely linked to parvovirus B19 infection.
  • Among these cases, 29 children needed intensive care and there were eight fatalities, emphasizing the severity of the situation.
  • The study suggests a need for better diagnosis, enhanced monitoring, and standardized treatment strategies, as only about one-third of affected children received effective intravenous immunoglobulins.

Sore throat represents one of the main causes of antibiotic overprescription in children. Its management is still a matter of debate, with countries considering streptococcal pharyngotonsillitis a benign and self-limiting condition and others advocating for its antibiotic treatment to prevent suppurative complications and acute rheumatic fever. Italian paediatricians frequently prescribe antibiotics on a clinical basis regardless of microbiological results.

  • The study looked at how serious Human Adenovirus (HAdV) infections are compared to other viral illnesses in kids with breathing problems in Italy.
  • They found that kids with HAdV showed more inflammation but didn't have worse breathing issues than those with other viruses.
  • The research highlights the need to identify HAdV early to avoid giving unnecessary antibiotics, since many kids might get treated for bacterial infections when they really have a virus.

  • Acute infectious diarrhea (AID) is a common illness in children worldwide, and probiotics are considered a promising treatment due to their effects on gut health and immune response.* -
  • The effectiveness of probiotics varies by strain and dosage, and guidelines recommend using specific strains with proven safety and efficacy for AID treatment.* -
  • While probiotics have strong support for treating AID in children, their role in preventing diarrhea in healthy individuals is uncertain, though they may help at-risk groups and in preventing hospital-acquired diarrhea.*

Since January 2024, Italy experiences a pertussis outbreak, primarily affecting neonates and unvaccinated infants at high risk of severe complications and mortality; 11 major paediatric centres noted 108 hospitalisations and three deaths by 10 May. The outbreak reflects increased circulation of and non-adherence to immunisation recommendations during pregnancy. Public health interventions, including maternal immunisation, vaccination of infants as early as possible and post-exposure prophylaxis, are critical for reducing the burden of pertussis and preventing further mortality.

Acute Bacterial Skin and Skin Structure Infections (ABSSSI) are marked by substantial morbidity, frequent need for hospitalization, and long courses of intravenous antibiotic therapy. Herein, we report four cases of pediatric patients admitted for ABSSSI and managed with a combination antibiotic regimen incorporating dalbavancin: a second-generation lipoglycopeptide active against Gram-positive bacteria, including methicillin-resistant . In our experience, particularly in a setting with a high methicillin-resistance rate, dalbavancin demonstrated safety and efficacy, simplifying ABSSSI management in childhood.

Introduction: In Italy Rotavirus vaccination (RVV) is provided free of charge from 2018, however, the coverage is scattered and suboptimal. The narrow time frame to complete the schedule is a barrier to uptake, and co-administration with other vaccines may potentially increase the coverage. Although the co-administration of RV vaccine and Meningococcal Group B vaccine (MenB) is not included in the product labels, we aimed at studying its impact on RVV coverage.

The Spike protein of SARS-CoV-2 acts as an enterotoxin able to induce chloride secretion and production of reactive oxygen species (ROS), involved in diarrhea pathogenesis. (LGG) is recommended in pediatric acute gastroenteritis guidelines as a therapy independent of infectious etiology. We tested a postbiotic preparation of LGG (mLGG) in an in vitro model of COVID-associated diarrhea.
