Invasive infections caused by Streptococcus pyogfenes (iGAS), commonly known as Group A Streptococcus, represent a significant public health concern due to their potential for rapid progression and life-threatening complications. Epidemiologically, invasive GAS infections exhibit a diverse global distribution, affecting individuals of all ages with varying predisposing factors. The pathogenesis of invasive GAS involves an array of virulence factors that contribute to tissue invasion, immune evasion, and systemic dissemination. In pediatrics, in the last few years, an increase in iGAS infections has been reported worldwide becoming a challenging disease to diagnose and treat promptly. This review highlights the current knowledge on pathogenesis, clinical presentations, and therapeutic approaches for iGAS in children. [ABSTRACT FROM AUTHOR]

LATENT infection , *TUBERCULOSIS , *LYMPHOCYTES , *JUVENILE diseases , *SENSITIVITY & specificity (Statistics) - Abstract
Aim: Higher number of monocytes and neutrophils may correlate with active tuberculosis (TB) in children. However, the few paediatric studies available are limited by the small numbers of children with TB disease or infection included. Methods: We calculated the monocyte‐to‐lymphocyte‐ratio (MLR), neutrophil‐to‐lymphocyte‐ratio (NLR) and neutrophil‐to‐monocyte‐plus‐lymphocyte‐ratio (NMLR) in children with active TB, latent TB infection (LTBI), other infectious and non‐infectious conditions and healthy children evaluated in two referral centres in Rome. Results: Overall, 649 children were included (41.8% females, mean age of 5.74 years). MLR, NLR and NMLR values were always significantly higher in patients with TB compared with the other groups (p < 0.001). Considering the entire population with the outcome of TB diagnosis, NMLR, with a cut‐off of 1.2, had a sensitivity of 63% and a specificity of 76% (AUC: 0.71 [0.64–0.78]); NLR, with a cut‐off of 1.5, had a sensitivity of 61% and a specificity of 79% (AUC: 0.72 [0.65–0.79]); MLR, considering a cut‐off of 0.2, was less sensitive (56%) but more specific (82%) with a similar AUC (0.72 [0.65–0.79]). Conclusion: Our study provides further evidence that MLR, NLR and NMLR can serve as first level diagnostics to support the clinical suspicion of TB in children. [ABSTRACT FROM AUTHOR]

Background: The spread of carbapenem-resistant organisms (CROs) is an increasingly serious threat globally, especially in vulnerable populations, such as intensive care unit (ICU) patients. Currently, the antibiotic options for CROs are very limited, particularly in pediatric settings. We describe a cohort of pediatric patients affected by CRO infections, highlighting the important changes in carbapenemase production in recent years and comparing the treatment with novel cephalosporins (N-CEFs) to Colistin-based regimens (COLI). Methods: All patients admitted to the cardiac ICU of the Bambino Gesù Children's Hospital in Rome during the 2016–2022 period with an invasive infection caused by a CRO were enrolled. Results: The data were collected from 42 patients. The most frequently detected pathogens were Pseudomonas aeruginosa (64%), Klebsiella pneumoniae (14%) and Enterobacter spp. (14%). Thirty-three percent of the isolated microorganisms were carbapenemase producers, with a majority of VIM (71%), followed by KPC (22%) and OXA-48 (7%). A total of 67% of patients in the N-CEF group and 29% of patients in the comparative group achieved clinical remission (p = 0.04). Conclusion: The increase over the years of MBL-producing pathogens in our hospital is challenging in terms of therapeutic options. According to the present study, N-CEFs are a safe and effective option in pediatric patients affected by CRO infections. [ABSTRACT FROM AUTHOR]

Coronavirus disease 2019 (COVID-19) and tuberculosis (TB) are currently two major causes of death among infectious diseases. Active tuberculosis and a history of tuberculosis appear to be associated with an increased risk of COVID-19. This coinfection, named COVID-TB, was never described in previously healthy children. We report three cases of pediatric COVID-TB. We describe three girls affected by tuberculosis, who tested positive for SARS-CoV-2. The first patient is a 5-year-old girl who was hospitalized for recurrent TB lymphadenopathy. As she never had any complications related to the concomitant infection with SARS-CoV-2, she received TB treatment. The second case is a 13-year-old patient with a history of pulmonary and splenic tuberculosis. She was admitted to the hospital due to deteriorating respiratory dynamics. She was already undergoing treatment for TB, but in the absence of improvement, she also required treatment for COVID-19. Slowly, the general condition improved until discharge. The last patient, a 10-year-old girl, was hospitalized for supraclavicular swelling. The investigations showed disseminated TB characterized by lung and bone involvement without COVID-19-related complications. She was treated with antitubercular and supportive therapy. Based on the data obtained from the adult population and our small experience, a pediatric patient with COVID-TB infection should be considered potentially at risk of worse clinical outcomes; for this reason, we suggest close observation, careful clinical management, and consideration of targeted anti-SARS-CoV-2 therapies.

Rationale: In 2016, a new interferon-gamma release assay (IGRA) was introduced, QuantiFERON-TB Gold Plus (QFT-Plus), claimed to have improved sensitivity in active tuberculosis (TB).Objectives: This study aimed to determine the performance of QFT-Plus, compared with previous generation IGRAs and the tuberculin skin test (TST), in children with TB in Europe.Methods: Multicentre, ambispective cohort study within the Paediatric Tuberculosis Network European Trials Group (ptbnet), a dedicated paediatric TB research network comprising >300 members, capturing TB cases <18 years-of-age diagnosed between January 2009 and December 2019.Measurements and Main Results: 1001 TB cases from 16 countries were included (mean age (IQR) 5.6 (2.4-12.1) years). QFT-Plus was performed in 358, QFT Gold in-Tube (QFT-GIT) in 600, T-SPOT.TB in 58 and TST in 636 cases. The overall test sensitivities were: QFT-Plus 83.8% (95% CI 80.2% to 87.8%), QFT-GIT 85.5% (95% CI 82.7% to 88.3%), T-SPOT.TB 77.6% (95% CI 66.9% to 88.3%) and TST (cut-off ≥10 mm) 83.3% (95% CI 83.3% to 86.2%). There was a trend for tests to have lower sensitivity in patients with miliary and/or central nervous system (CNS) TB (73.1%, 70.9%, 63.6% and 43.5%, respectively), and in immunocompromised patients (75.0%, 59.6%, 45.5% and 59.1%, respectively).Conclusions: The results indicate that the latest generation IGRA assay, QFT-Plus, does not perform better than previous generation IGRAs or the TST in children with TB disease. Overall, tests performed worse in CNS and miliary TB, and in immunocompromised children. None of the tests evaluated had sufficiently high sensitivity to be used as a rule-out test in children with suspected TB. [ABSTRACT FROM AUTHOR]- Published

Tuberculosis remains (TB) to be one of the most common causes of child morbidity and mortality. Abdominal TB is not frequently diagnosed and, although its incidence is not definitively established, there are data that seem to indicate that it accounts for approximately 1–3% of all pediatric TB cases and for no more than 10% of those with extrapulmonary manifestations. It seems, however, that abdominal TB is significantly more common than usually thought as signs and symptoms are non-specific and may mimic other diseases. The delayed or wrong diagnosis of pediatric abdominal TB can have dramatic consequences as they can lead to untreated TB with miliary dissemination, unnecessary surgery, or dangerous drug therapies. This report describes five cases of abdominal TB diagnosed among 216 pediatric patients admitted for TB in Italy from 2011 to 2021. Our cases evidence that abdominal TB is a complex and potentially very severe disease that, when not appropriately diagnosed, may be associated with severe complications and prolonged anti-TB therapy. Discussion among specialists is crucial to achieve an early diagnosis and to promptly start the anti-TB treatment. Further studies are needed to clarify the appropriate duration of therapy as well as management of MDR abdominal TB cases. [ABSTRACT FROM AUTHOR]

During the COVID-19 pandemic, the lung ultrasound (LU) turned out to be a pivotal tool to study the lung involvement in the adult population, but the same was not well evaluated in children. We detected the LU patterns through an integrated approach with clinical–laboratory features in children hospitalized for COVID-19 in relation to the temporal trend of the Italian epidemic. We conducted a retrospective study which took place at a pediatric tertiary hospital from 15 March 2020 to 15 March 2021. We compared the characteristics of the initial phase of the first COVID-19 year—in the spring and summer (15 March–30 September 2020)—and those of the second phase—in the autumn and winter (1 October 2020–15 March 2021). Twenty-eight patients were studied both in the first and in the second phase of the first COVID-19 year. The disease severity score (DSS) was significantly greater in the second phase (p = 0.015). In the second phase of the first COVID-19 year, we detected a more significant occurrence of the following LU features than in the first phase: the irregular pleural line (85.71% vs. 60.71%; p = 0.035), the B-lines (89.29% vs. 60%; p = 0.003) and the several but non-coalescent B-lines (89.29% vs. 60%; p = 0.003). The LU score correlated significantly with the DSS, with a moderate relationship (r = 0.51, p < 0.001). The combined clinical, laboratory and ultrasound approaches might be essential in the evaluation of pulmonary involvement in children affected by COVID-19 during different periods of the pandemic.

Background: Although SARS‐CoV‐2 immunizations have started in most countries, children are not currently included in the vaccination programs; thus, it remains crucial to define their anti‐SARS‐CoV‐2 immune response in order to minimize the risk for other epidemic waves. This study sought to provide a description of the virology ad anti‐SARS‐CoV‐2 immunity in children with distinct symptomatology. Methods: Between March and July 2020, we recruited 15 SARS‐CoV‐2 asymptomatic (AS) and 51 symptomatic (SY) children, stratified according to WHO clinical classification. We measured SARS‐CoV‐2 viral load using ddPCR and qPCR in longitudinally collected nasopharyngeal swab samples. To define anti‐SARS‐CoV‐2 antibodies, we measured neutralization activity and total IgG load (DiaSorin). We also evaluated antigen‐specific B and CD8+T cells, using a labeled S1+S2 protein and ICAM expression, respectively. Plasma protein profiling was performed with Olink. Results: Virological profiling showed that AS patients had lower viral load at diagnosis (p =.004) and faster virus clearance (p =.0002) compared with SY patients. Anti‐SARS‐CoV‐2 humoral and cellular response did not appear to be associated with the presence of symptoms. AS and SY patients showed similar titers of SARS‐CoV‐2 IgG, levels of neutralizing activity, and frequency of Ag‐specific B and CD8+ T cells, whereas pro‐inflammatory plasma protein profile was found to be associated with symptomatology. Conclusion: We demonstrated the development of anti‐SARS‐CoV‐2 humoral and cellular response with any regard to symptomatology, suggesting the ability of both SY and AS patients to contribute toward herd immunity. The virological profiling of AS patients suggested that they have lower virus load associated with faster virus clearance. [ABSTRACT FROM AUTHOR]

Background: Acute cerebellitis (AC) and acute cerebellar ataxia (ACA) are the principal causes of acute cerebellar dysfunction in childhood. Nevertheless. there is no accepted consensus regarding the best management of children with AC/ACA: the aim of the study is both to assess clinical, neuroimaging and electrophysiologic features of children with AC/ACA and to evaluate the correlation between clinical parameters, therapy and outcome. Methods: A multicentric retrospective study was conducted on children ≤ 18 years old admitted to 12 Italian paediatric hospitals for AC/ACA from 01/01/2003 to 31/12/2013. A score based on both cerebellar and extracerebellar signs/symptoms was computed for each patient. One point was given for each sign/symptom reported. Severity was divided in three classes: low, moderate, severe. Results: A total of 124 children were included in the study. Of these, 118 children received a final diagnosis of ACA and 6 of AC. The most characteristic finding of AC/ACA was a broad-based gait disturbance. Other common symptoms included balance disturbances, slurred speech, vomiting, headache and fever. Neurological sequelae were reported in 6 cases (5%) There was no correlation among symptoms, cerebrospinal fluid findings, clinical outcome. There was no correlation between clinical manifestations and clinical score on admission and length of hospital stay, sex, age and EEG findings with sequelae (P > 0.05). Children with pathological magnetic resonance imaging (MRI) or computed tomography (CT) had a higher probability of having clinical sequelae. Treatment was decided independently case by case. Patients with a higher clinical score on admission had a higher probability of receiving intravenous steroids. Conclusions: We confirmed the literature data about the benign course of AC/ACA in most cases but we also highlighted a considerable rate of patients with neurological sequelae (5%). Pathological MRI or CT findings at admission correlate to neurological sequelae. These findings suggest the indication to perform an instrumental evaluation in all patients with AC/ACA at admission to identify those at higher risk of neurological outcome. These patients may benefit from a more aggressive therapeutic strategy and should have a closer follow-up. Randomized controlled trials are needed to confirm these observations. The ultimate goal of these studies could be to develop a standardized protocol on AC/ACA. The MRI/CT data, associated with the clinical manifestations, may allow us to define the class risk of patients for a neurological outcome. [ABSTRACT FROM AUTHOR]

TUBERCULOSIS in children ,CHILDREN ,TUBERCULOSIS patients ,CHILDREN'S hospitals ,CHILD mortality - Abstract
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.

Spinocerebellar ataxia type 2 (SCA2) is a late-onset autosomal dominant cerebellar ataxia caused by triplet CAG/CTG expansion in the ATX2 gene. The initial symptoms usually appear when subjects are in their 30s. Pediatric onset is less common and usually associated with larger triplet expansions. We here report the case of a 1-year-old girl who presented with facial dysmorphism, dystonic features, developmental delay, and retinitis pigmentosa. She was diagnosed as carrying an expanded CAG/CTG tract (92 repeats) before a molecular diagnosis of SCA2 was made in her father. Facial dysmorphism associated with developmental delay and retinitis pigmentosa in early childhood should prompt a careful family investigation for ataxia and study of ATX2. [ABSTRACT FROM AUTHOR]

NK cell cytotoxicity in Chédiak-Higashi syndrome (CHS) is strongly impaired as lytic granules are not released upon NK-target cell contact, contributing to several defects typical of this severe immunodeficiency. Correction of NK cell defects in CHS should improve the outcome of hematopoietic stem-cell transplantation, proposed as therapy. We investigated NK cell functions in a CHS patient before and after cord-blood transplantation, and the ability of in vitro IL-2 treatment to restore them. Before the transplant, the strong defect in NK cell-mediated natural and antibody-dependent cytotoxicity, as well as in IFN-γ production, could be restored up to normal levels by in vitro IL-2 treatment. This cytokine also caused the appearance of smaller lysosomal granules and their orientation towards the NK-target cell contact area, thus suggesting that IL-2 had a more general capacity to restore NK cell effector functions. Moreover after the transplant, although the successful engraftment, NK cell cytotoxicity resulted still partially impaired at one year, almost normal at ten years and, anyhow, fully recovered by in vitro IL-2 treatment. Taken together, our results indicate that IL-2 had a wide capacity to restore NK cell effector functions, being able to reverse the altered cytotoxic activity, lytic granule pattern, and cytokine production observed in the CHS patient.
