Data on features of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in children and adolescents are scarce. We report preliminary results of an Italian multicentre study comprising 168 laboratory-confirmed paediatric cases (median: 2.3 years, range: 1 day–17.7 years, 55.9% males), of which 67.9% were hospitalised and 19.6% had comorbidities. Fever was the most common symptom, gastrointestinal manifestations were frequent; two children required intensive care, five had seizures, 49 received experimental treatments and all recovered.

BACKGROUND: The major burden of acute gastroenteritis (AGE) in childhood is related to its high frequency and the large number of hospitalizations, medical consultations, tests and drug prescriptions. The adherence to evidence-based recommendations for AGE management in European countries is unknown. The purpose of the study was to compare hospital medical interventions for children admitted for AGE with recommendations reported in the European Societies of Pediatric Gastroenterology, Hepatology and Nutrition and Pediatric Infectious Diseases guidelines. METHODS: A multicenter prospective study was conducted in 31 Italian hospitals. Data on children were collected through an online clinical reporting form and compared with European Societies of Pediatric Gastroenterology, Hepatology and Nutrition and Pediatric Infectious Diseases guidelines for AGE. The main outcomes were the inappropriate hospital admissions and the percentage of compliance to the guidelines (full >90%, partial >80% compliance) based on the number and type of violations to evidence-based recommendations. RESULTS: Six-hundred and twelve children (53.6% male, mean age 22.8 ± 15.4 months) hospitalized for AGE were enrolled. Many hospital admissions (346/602, 57.5%) were inappropriate. Once admitted, 20.6% (126/612) of children were managed in full compliance with the guidelines and 44.7% (274/612) were managed in partial compliance. The most common violations were requests for microbiologic tests (404; 35.8%), diet changes (310; 27.6%) and the prescription of non-recommended probiotics (161; 14.2%), antibiotics (103; 9.2%) and antidiarrheal drugs (7; 0.6%). CONCLUSIONS: Inappropriate hospital admissions and medical interventions are still common in the management of children with AGE in Italy. Implementation of guidelines recommendations is needed to improve quality of care

Bacillus Calmette-Guerin (BCG) vaccine is still the only vaccine approved for the prevention of tuberculosis (TB), and is widely used in highly endemic countries, where all newborns receive a single intradermal dose immediately after birth; however, the recommendations concerning its use in Europe vary widely from country to country. This document describes the recommendations of a group of Italian scientific societies concerning its pediatric use in Italy, the persistence of the protection it provides, its safety, its interference with tuberculin skin test (TST) responses, and the children who should be vaccinated. The experts conclude that BCG vaccination provides a good level of protection against tuberculous meningitis and disseminated forms, and a fair level of protection against pulmonary disease; the protective effective lasts at least 10 years, and revaccination offers no advantages over a single administration. The vaccine is safe in immunocompetent subjects, and affects the response to a TST for at least 6 y On the basis of these observations, we recommend its use in Italy in all TST-negative immunocompetent newborns and breastfeeding infants aged

Clostridium difficile infection (CDI) is increasingly found in children worldwide, but limited data are available from children living in southern Europe. A 6-year retrospective study was performed to investigate the epidemiology, clinical features, treatment, and risk of recurrence in Italy. Data of children with community- and hospital-acquired CDI (CA-CDI and HA-CDI, respectively) seen at seven pediatric referral centers in Italy were recorded retrospectively. Annual infection rates/10,000 hospital admissions were calculated. Logistic regression was used to investigate risk factors for recurrence. A total of 177 CDI episodes was reported in 148 children (83 males, median age 55.3 months), with a cumulative infection rate of 2.25/10,000 admissions, with no significant variability over time. The majority of children (60.8 %) had CA-CDI. Children with HA-CDI (39.2 %) had a longer duration of symptoms and hospitalization (p = 0.003) and a more common previous use of antibiotics (p = 0.0001). Metronidazole was used in 70.7 % of cases (87/123) and vancomycin in 29.3 % (36/123), with similar success rates. Recurrence occurred in 16 children (10.8 %), and 3 (2 %) of them presented a further treatment failure. The use of metronidazole was associated with a 5-fold increase in the risk of recurrence [odds ratio (OR) 5.18, 95 % confidence interval (CI) 1.1-23.8, p = 0.03]. Short bowel syndrome was the only underlying condition associated with treatment failure (OR 5.29, 95 % CI 1.17-23.8, p = 0.03). The incidence of pediatric CDI in Italy is low and substantially stable. In this setting, there is a limited risk of recurrence, which mainly concerns children treated with oral metronidazole and those with short bowel syndrome.

Tuberculosis (TB) is one of the leading causes of death worldwide. Over the last decades, TB has also emerged in the pediatric population. Epidemiologic data of childhood TB are still limited and there is an urgent need of more data on very large cohorts. A multicenter study was conducted in 27 pediatric hospitals, pediatric wards, and public health centers in Italy using a standardized form, covering the period of time between 1 January 2010 and 31 December 2012. Children with active TB, latent TB, and those recently exposed to TB or recently adopted/immigrated from a high TB incidence country were enrolled. Overall, 4234 children were included; 554 (13.1%) children had active TB, 594 (14.0%) latent TB and 3086 (72.9%) were uninfected. Among children with active TB, 481 (86.8%) patients had pulmonary TB. The treatment of active TB cases was known for 96.4% (n = 534) of the cases. Overall, 210 (39.3%) out of these 534 children were treated with three and 216 (40.4%) with four first-line drugs. Second-line drugs where used in 87 (16.3%) children with active TB. Drug-resistant strains of Mycobacterium tuberculosis were reported in 39 (7%) children. Improving the surveillance of childhood TB is important for public health care workers and pediatricians. A non-negligible proportion of children had drug-resistant TB and was treated with second-line drugs, most of which are off-label in the pediatric age. Future efforts should concentrate on improving active surveillance, diagnostic tools, and the availability of antitubercular pediatric formulations, also in low-endemic countries.

Allogeneic BMT represents the only chance of cure for beta-thalassemia. Occasionally, two affected individuals from the same family share a matched healthy sibling. Moreover, a high incidence of transplant rejection is still observed in Pesaro class III patients, requiring a second BMT procedure. In these settings, one option is to perform a second BM harvest from the same donor. Although BM harvest is a safe procedure in children, ethical issues concerning this invasive practice still arise. Here, we describe our series of seven pediatric, healthy donors, who donated BM more than once in favor of their beta-thalassemic HLA-identical siblings between June 2005 and January 2008. Three donors donated BM twice to two affected siblings and four donors donated twice for the same sibling following graft rejection of the first BMT. All donors tolerated the procedures well and no relevant side effects occurred. There was no significant difference between the two harvests concerning cell yield and time to engraftment. Our experience shows that for pediatric donors, a second BM donation is safe and feasible and good cellularity can be obtained. We suggest that a second harvest of a pediatric donor can be performed when a strong indication for BMT exists. Allogeneic BMT represents the only chance of cure for beta-thalassemia.
