Neumonía por COVID-19 en niños: De su etiología a su manejo

El COVID-19 es menos serio en niños que en adultos. Sin embargo, las afecciones respiratorias dominan el cuadro clínico de pacientes hospitalizados por COVID-19, aun en niños. En algunas series de casos, el deterioro del estado clínico, donde la disnea, la cianosis y el inicio del síndrome de dificultad respiratoria aguda (SDRA) emergieron ∼8–10 días después del inicio de la infección por SARS-CoV-2, pudo progresar rápidamente hasta la falla multiorgánica y la muerte. Esta revisión tiene como objetivo evaluar las características de la neumonía por COVID-19 en poblaciones pediátricas, comenzando con su etiología y sus mecanismos patológicos, para cerrar con su manejo clínico

Inter-society consensus for the use of inhaled corticosteroids in infants, children and adolescents with airway diseases

Background: In 2019, a multidisciplinary panel of experts from eight Italian scientific paediatric societies developed a consensus document for the use of inhaled corticosteroids in the management and prevention of the most common paediatric airways disorders. The aim is to provide healthcare providers with a multidisciplinary document including indications useful in the clinical practice. The consensus document was intended to be addressed to paediatricians who work in the Paediatric Divisions, the Primary Care Services and the Emergency Departments, as well as to Residents or PhD students, paediatric nurses and specialists or consultants in paediatric pulmonology, allergy, infectious diseases, and ear, nose, and throat medicine. Methods: Clinical questions identifying Population, Intervention(s), Comparison and Outcome(s) were addressed by methodologists and a general agreement on the topics and the strength of the recommendations (according to the GRADE system) was obtained following the Delphi method. The literature selection included secondary sources such as evidence-based guidelines and systematic reviews and was integrated with primary studies subsequently published. Results: The expert panel provided a number of recommendations on the use of inhaled corticosteroids in preschool wheezing, bronchial asthma, allergic and non-allergic rhinitis, acute and chronic rhinosinusitis, adenoid hypertrophy, laryngitis and laryngospasm. Conclusions: We provided a multidisciplinary update on the current recommendations for the management and prevention of the most common paediatric airways disorders requiring inhaled corticosteroids, in order to share useful indications, identify gaps in knowledge and drive future research

Vitamin D status can affect COVID-19 outcomes also in pediatric population

Background: vitamin D influences the immune system and the inflammatory response. It is known that vitamin D supplementation reduces the risk of acute respiratory tract infection. In the last two years, many researchers have investigated vitamin D's role in the pathophysiology of COVID-19 disease. Results: the findings obtained from clinical trials and systematic reviews highlight that most patients with COVID19 have decreased vitamin D levels and low levels of vitamin D increase the risk of severe disease. This evidence seems to be also confirmed in the pediatric population. Conclusions: further studies (systematic review and meta-analysis) conducted on children are needed to confirm that vitamin D affects COVID-19 outcomes and to determine the effectiveness of supplementation and the appropriate dose, duration and mode of administration

Mometasone furoate nasal spray in Italian children with seasonal allergic rhinitis: a comprehensive assessment

Objective: Seasonal allergic rhinitis (SAR) is a common disease of childhood and is characterized by type 2 inflammation, bothersome symptoms, and impaired quality of life (QoL). Intranasal corticosteroids are effective medications in managing SAR. In addition, mometasone furoate nasal spray (MFNS) is a well-known therapeutic option. However, the literature provided no data about the effects of MFNS in European children with SAR. Thus, this study addressed this unmet requirement.Methods: MFNS was compared to isotonic saline. Both treatments were prescribed: one drop of spray per nostril, twice a day, for 3 weeks. Nasal cytology, total symptom score (TSS), visual analogic scale concerning the parental perception of severity of symptoms, and the Pediatric Rhinoconjunctivitis Quality of Life Questionnaire (PRQLQ) were assessed at baseline, after 7 and 21 days, and 1 month after discontinuation.Results: MFNS significantly reduced eosinophil and mast cell counts, improved QoL, and relieved symptoms, as assessed by doctors and perceived by parents. These effects persisted over time, even after discontinuation. Both treatments were safe and well-tolerated.Conclusions: The present study documented that a 3-week MFNS treatment was able to significantly dampen type 2 inflammation, improve QoL, and reduce severity of symptoms in Italian children with SAR, and was safe.

Bifidobacterium mixture (B longum BB536, B infantis M-63, B breve M-16V) treatment in children with seasonal allergic rhinitis and intermittent asthma

Background: Allergic rhinitis (AR) and allergic asthma are caused by an IgE-mediated inflammatory reaction. Probiotics may exert anti-inflammatory and immune-modulatory activity. Thus, this study aimed at investigating whether a Bifidobacteria mixture could be able to relieve nasal symptoms, and affect quality of life (QoL) in children with AR and intermittent asthma due to Parietaria allergy. Materials and methods: The present study was conducted as placebo-controlled, double-blinded, and randomized. Globally, 40 children (18 males; mean age 9 ± 2.2 years) were enrolled. They were treated with probiotics or placebo: 1 sachet/day for 4 weeks. AR symptoms, and QoL were assessed at baseline and after treatment. Use of rescue medications, such as cetirizine syrup and salbutamol spray, was also permitted and recorded. Results: Children treated with probiotic mixture achieved a significant improvement of symptoms (p < 0.005), and QoL ((p < 0.001). Placebo group had worsening of symptoms (p < 0.005) and QoL (p < 0.001). The use of rescue medications was overlapping in the two groups. The intergroup analysis showed that probiotic mixture was significantly superior than placebo for all parameters. Conclusions: The current study demonstrated that a Bifidobacteria mixture was able of significantly improving AR symptoms and QoL in children with pollen-induced AR and intermittent asthma.

High-dose inhaled flunisolide versus budesonide in the treatment of acute asthma exacerbations in preschool-age children.

The role of inhaled corticosteroids in asthma exacerbation is debated. We compared high doses of nebulized budesonide versus high doses of nebulized flunisolide, in association with a short-acting beta-2-agonist, in the treatment of moderate asthma exacerbation in preschool children. In this randomized, parallel group, simple blind study, 46 children aged between 3 and 5 years affected by an acute moderate asthma attack were treated with nebulized flunisolide (Group 1) 40 μg/kg twice daily for 7 days and then 20 μg/kg twice daily for 14 days, or with nebulized budesonide (Group 2) 0.5 mg twice daily for 7 days then 0.25 mg twice daily for 15 days. Inhaled salbutamol (MDI+ spacer - 200 μg 4 times daily) was administered during the first 3 days of the study and then as needed. At T0, T7 and T21 days, airway resistances were evaluated with the forced oscillation technique before and after inhalation of inhaled salbutamol (200 mcg). Parents recorded symptoms and drug use on a diary card. Forty children completed the study. Airways resistances were significantly reduced at T7 (p&lt; 0.01 flunisolide; p&lt; 0.05 budesonide) and T21 (p&lt; 0.05 flunisolide; p&lt; 0.05 budesonide) versus T0 in both groups, although at T7 the reduction occurred faster in group 1 than in group 2 (p&lt;0.01). During the first 7 days of treatment, symptom scores decreased in both groups; however, the decrease was greater in group 1 (p&lt; 0.05). High doses of inhaled flunisolide and budesonide are both effective in the management of moderate asthma exacerbations in pre-school-age children, but the flunisolide therapeutic effect was faster than budesonide

Overview on the treatment of severe bronchial asthma

Childhood asthma, often linked with atopic conditions, poses a challenge when classified as severe and uncontrolled. The 2023 GINA guidelines define severe asthma in children as asthma that remains uncontrolled despite optimized treatment with high-dose ICS-LABA or requires high-dose ICS-LABA to prevent it from becoming uncontrolled. This category encompasses about 5% of pediatric asthma cases, emphasizing the need for innovative therapeutic exploration. Advances in understanding asthma phenotypes and endotypes enable personalized treatment based on biomarkers. Monoclonal antibodies offer targeted solutions, reducing exacerbations, improving lung function, and minimizing corticosteroid use in pediatric patients. Integrating these therapies requires a personalized approach by healthcare providers, enhancing outcomes in severe and refractory cases
