Article Synopsis
  • The Omicron variant of SARS-CoV-2 has shown significant variability and clinical differences from earlier clades, with four lineages (BA.1, BA.2, BA.5, BQ.1) circulating in children since late 2021.
  • A large proportion (70%) of infections occurred in children under the age of 1, primarily involving the BA.2 lineage, indicating a specific demographic vulnerability.
  • The study identified 69 significant SNPs (single nucleotide polymorphisms) related to viral genetic variability, with certain clusters associated with moderate to severe COVID-19 cases and comorbidities, suggesting viral diversity may influence the severity of disease.

Objective: The main aim of this study was to define the best treatment option for multisystem inflammatory syndrome in children (MIS-C) and to analyse the role of anakinra.

Methods: This is a multicentre retrospective cohort study. Patients were treated according to the attending physician's decision.

Aim: Concerns have been raised about possible neuropsychiatric sequelae of COVID-19. The objective of this study was to examine the plausibility of long-term mental health consequences of COVID-19 by assessing a sample of children after the resolution of the acute SARS-CoV-2 infection.

Method: As part of a systematic follow-up assessment of pediatric patients with COVID-19 conducted at two university children's hospitals, 50 children (56% males) aged 8 to 17 years (median 11.

Importance: Severe gastrointestinal (GI) manifestations have been sporadically reported in children with COVID-19; however, their frequency and clinical outcome are unknown.

Objective: To describe the clinical, radiological, and histopathologic characteristics of children with COVID-19 presenting with severe GI manifestations to identify factors associated with a severe outcome.

Design, Setting, And Participants: A multicenter retrospective cohort study (February 25, 2020, to January 20, 2021) enrolled inpatient and outpatient children (aged <18 years) with acute SARS-CoV-2 infection, confirmed by positive real-time reverse-transcriptase-polymerase chain reaction on nasopharyngeal swab or fulfilling the US Centers for Disease Control and Prevention criteria for multisystem inflammatory syndrome in children (MIS-C).

Background: Central line-associated bloodstream infections (CLABSI) are significant cause of complications in pediatric intensive care units (PICUs). An emerging challenge are CLABSIs in children with medical complexity (CMC) admitted to PICU. CMC are patients with chronic conditions with or without neurological impairment needing for tracheostomy and/or home mechanical or non-invasive ventilation and/or gastrostomy/jejunostomy.

The role of Plasmodium in the etiology of acute diarrhea in developing countries remains controversial, and gastrointestinal (GI) symptoms are inconsistently reported in malaria. In this observational case-control study, we investigated the prevalence and risk factors for GI symptoms in hospitalized malarious children aged 1 month to 5 years in northern Uganda. Children with a diagnosis of Plasmodium falciparum malaria were enrolled as cases, and feverish children in whom malaria was excluded were enrolled as controls.

Article Synopsis
  • Recent concerns have emerged regarding the risk of COVID-19 transmission from pregnant mothers to their newborns, prompting discussions on how to safely manage childbirth and postnatal care, including breastfeeding.
  • A study involving five mother-child pairs in Italy revealed that while four neonates tested positive for COVID-19, most were asymptomatic or showed mild symptoms, particularly gastrointestinal issues.
  • The study suggests that decisions about separating COVID-positive mothers from their infants should be personalized, considering various factors such as the family's wishes and local health conditions.

The recent global COVID-19 public health emergency is caused by SARS-CoV-2 infections and can manifest extremely variable clinical symptoms. Host human genetic variability could influence susceptibility and response to infection. It is known that ACE2 acts as a receptor for this pathogen, but the viral entry into the target cell also depends on other proteins.

Background: Italy is classified as a low tuberculosis (TB) incidence country (rate 6.5/100,000 inhabitants). However, the Campania Region Pediatric Reference Centre (CRRC) observed an increase in TB, contemporarily with a rise in migration.

We evaluated severe acute respiratory syndrome coronavirus 2 RNA clearance in 22 children. The estimation of positivity at day 14 was 52% for nasopharyngeal swab and 31% for stool samples. These data underline the significance of nasopharyngeal and stoolsample for detecting infected children.

The incidence of gastroenteritis has greatly reduced due to improved hygiene conditions in developing countries and the use of rotavirus vaccine. Still thousands of children, however, die from gastroenteritis, most of them in poor countries. Yet gastroenteritis management is simple, inexpensive, and effective and is largely the same all over the world.

Background: Treatment of HIV infection in adolescents is challenging due to long duration of therapy and poor adherence. Recently, the integrase strand transfer inhibitor dolutegravir (DTG) has been approved for the use in adolescents with HIV, but evidence in clinical practice is very limited.

Methods: We describe six cases of HIV-infected children/adolescents successfully treated with DTG-based regimen.

Aim: To verify the precision and accuracy of transglutaminase antibodies (TGA) assays across Mediterranean countries.

Methods: This study involved 8 referral centres for celiac disease (CD) in 7 Mediterranean countries. A central laboratory prepared 8 kits of 7 blinded and randomized serum samples, with a titrated amount of Human TGA IgA.

Background: We assessed how the diagnosis of Celiac Disease (CD) is made and how the new ESPGHAN guidelines can be applied in children from countries with different resources.

Methods: A real life prospective study was performed in 14 centres of 13 different Mediterranean countries. Participants were asked to apply the usual diagnostic work-up for CD according to their diagnostic facilities.

Background: We aimed at assessing the factors that can influence results of the dissemination of an already validated, new generation commercial Point-of-Care Test (POCT) for detecting celiac disease (CD), in the Mediterranean area, when used in settings where it was designed to be administered, especially in countries with poor resources.

Methods: Pragmatic study design. Family pediatricians at their offices in Italy, nurses and pediatricians in Slovenia and Turkey at pediatricians', schools and university primary care centers looked for CD in 3,559 (1-14 yrs), 1,480 (14-23 yrs) and 771 (1-18 yrs) asymptomatic subjects, respectively.

Objectives: The extent to which variation in taste perception influences food preferences is, to date, controversial. Bitterness in food triggers an innate aversion that is responsible for dietary restriction in children. We investigated the association among genetic variations in bitter receptor TAS2R38 and food choices in healthy children in the Mediterranean area, to develop appropriate tools to evaluate the relation among genetic predisposition, dietary habits, and feeding disorders.
