Prevalence of COVID-19 in children affected by allergic rhinoconjunctivitis and asthma: results from the second "SIAIP rhinosinusitis and conjunctivitis committee" survey

Treatment of Severe Asthma: Case Report of Fast Action of Mepolizumab in a Patient with Recent SARS-CoV-2 Infection

Asthma is one of the most common chronic inflammatory diseases of childhood with a heterogeneous impact on health and quality of life. Mepolizumab is an antagonist of interleukin-5, indicated as an adjunct therapy for severe refractory eosinophilic asthma in adolescents and children aged >6 years old. We present the case of a 9 year-old boy with severe asthma who experienced several asthmatic exacerbations following a SARS-CoV-2 infection, necessitating therapy with short-acting bronchodilators, oral corticosteroids, and hospitalization. We follow the patient using validated questionnaires for the evaluation of asthma control: Children Asthma Control Test, Asthma Control Questionnaire, respiratory function tests, and evaluation of exhaled nitric oxide fraction. After 12 weeks from the start of therapy with mepolizumab, we found significant improvements in lung function, a reduction in the degree of bronchial inflammation, and improvements in quality of life. No asthmatic exacerbations have been reported since the initiation of treatment with mepolizumab. Respiratory infections, such as those related to SARS-CoV-2, represent a significant risk factor for exacerbations in patients with moderate to severe forms of asthma. In our experience, following new episodes of exacerbation, the initiation of treatment with mepolizumab has allowed us to improve asthma control and enhance the quality of life of patients from the first doses. Although mepolizumab showed promise in this child with severe asthma during SARS-CoV-2 infection, the results from this single case cannot be generalized. Further studies are needed to confirm its safety and effectiveness.

[Cardiovascular manifestations in pediatric multisystem inflammatory syndrome associated with COVID-19 in a tertiary care pediatric center in Mexico City]

Objective

The objective is to expose the cardiovascular alterations in patients diagnosed with pediatric inflammatory multisystem syndrome (PIMS) associated with COVID-19 during the SARS-CoV-2 pandemic, in order to understand the disease, its evolution, and optimal management upon diagnosis.

Method

Retrospective, observational, cross-sectional analytical study of patients diagnosed with PIMS according to the criteria of the World Health Organization at the National Institute of Pediatrics, from March 2020 to December 2021.

Results

During the study period, 77 patients with PIMS were diagnosed. The results showed correlation between the shock state and alteration of laboratory markers (platelets 144217.29 ± 139321.6 μL [p < 0.001], procalcitonin 27.37 ± 38.37 ng/ml [p = 0.05] and ferritin 1937.87 ± 2562.63 [p < 0.001]). The ventricular function in patients with shock was significantly lower compared to those without shock (49.6 ± 9.1% vs. 58.1 ± 8.4 %; t-Student p < 0.001), as well as injury to the left coronary artery (p = 0.02). There is a correlation between NT-proBNP and ventricular dysfunction (Kruskal-Wallis p = 0.007). Statistical significance was found in the association between death, elevation of inflammatory markers and ventricular dysfunction (p < 0.001).

Conclusions

The cardiovascular alterations observed, in order of frequency, were pericardial effusion (25.7%), myocarditis (15%), mild ventricular dysfunction (13.5%) and small coronary aneurysm with predominance of the left coronary artery and the anterior descending one.

Rigid bronchoscopy: a consultant survey

INTRODUCTION

Inhalation of foreign bodies represents a potentially fatal emergency in both adults and children. Chest x-ray, in isolation, is neither sensitive nor specific. Rigid bronchoscopy represents the gold standard to diagnose and retrieve paediatric foreign bodies. Cases are encountered infrequently, creating anxieties about their management. Little is known about the confidence in, and maintenance of, rigid bronchoscopy skills by ear, nose and throat teams.

METHODS

A 15-question survey was completed by 50 practising otolaryngology consultants in England.

RESULTS

Results show that almost 40% of otolaryngology consultants covering rigid bronchoscopy have not performed bronchoscopy in more than 5 years. Consultants raised concerns about the anaesthetic support and the speed of equipment assembly. Questions on clinical practice showed disparities in practice in the same scenario.

CONCLUSIONS

The authors advocate addressing many of the issues raised by the study with a greater availability of simulation courses and regular scheduled intradepartmental teaching days for all professionals involved. National guidelines on criteria for transfer to tertiary centres would improve the consistency of practice.

COVID-19 Pediatric Follow-Up: Respiratory Long COVID-Associated Comorbidities and Lung Ultrasound Alterations in a Cohort of Italian Children

In children, the factors that influence COVID-19 disease and its medium- and long-term effects are little known. Our investigation sought to evaluate the presence of comorbidity factors associated with respiratory long COVID manifestations in children and to study ultrasound abnormalities following SARS-CoV-2 infection. Children, who arrived at the 'Respiratory Diseases of Pediatric Interest Unit' at the Department of Woman, Child, and General and Specialized Surgery of the University of Campania 'Luigi Vanvitelli', were selected during the timeframe from September 2021 to October 2022. The children were diagnosed with a SARS-CoV-2 infection that occurred at least one month before the visit. All patients followed a COVID-19 follow-up protocol, developed by the Italian Society of Pediatric Respiratory Diseases (SIMRI), which included: collection of data regarding SARS-CoV-2 illness and history of known respiratory and allergic diseases; physical examination; BMI assessment; baseline spirometry and after bronchodilation test; six-minute walking test; and lung ultrasound (LUS). In a cohort of 104 participants with respiratory long COVID symptoms (64.7% male, average age 8.92 years), 46.1% had fever with other symptoms, and 1% required hospitalization. BMI analysis showed 58.4% of the cohort was overweight. The LUS was positive in 27.0% of cases. A significant BMI association was observed with COVID-19 symptoms and LUS score (p-value < 0.05). No associations were found with asthma or atopy.

Year 2022: exploring COVID-19 pandemic in children

COVID-19 pandemics is rapidly changing. In this article, we review progresses published in the Italian Journal of Pediatrics in 2022. More data on clinical pictures, prevention strategies and active management in children have been provided. The continued evolution of knowledge has driven transformations in the clinical approach to the disease and allowed key advancements in the care of children with COVID-19.

Mental Health in the Post-Lockdown Scenario: A Scientometric Investigation of the Main Thematic Trends of Research

Since the outbreak of COVID-19, researchers and clinicians have published scientific articles on the SARS-CoV-2 virus and its medical, organizational, financial, and psychological implications. However, many effects have been observed in the post-lockdown scenario. In this study, we adopted a scientometric-bibliometric approach to drawing the state of the art regarding the emotional and psychological effects of the pandemic after the lockdown. In Scopus, we found 791 papers that were subsequently analyzed using CiteSpace. The document co-citation analysis (DCA) computation generated a network of eight major clusters, each representing a central area of investigation. Specifically, one major cluster-cluster no. 1-focuses on the long-term effects of the COVID-19 pandemic and individuals' ability to develop adaptive coping mechanisms and resilience. The results allow us to frame the fields covered by researchers more precisely and the areas that still need more investigation.

The longitudinal evaluation of COVID-19 in pediatric patients and the impact of delta variant

BACKGROUND

Pediatric patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) displayed milder symptoms than adults. However, they play an important role in case numbers and virus transmission. Therefore, we aimed to determine the epidemiological features of all pediatric patients infected with SARS-CoV-2 and put forth case numbers longitudinally throughout the delta variant dominant period.

METHODS

A retrospective study was conducted at a university hospital and included patients between 0 and18 years old with a SARS-CoV-2 polymerase chain reaction (PCR) positive result, including inpatients and outpatients. Epidemiological and clinical features were recorded from electronic files, and telephone visits were performed between March 2020 and December 2021.

RESULTS

During the study period, 3175 coronavirus disease 2019 (COVID-19) pediatric patients were admitted to our hospital with a mean age of 10.61 ± 4.6 years. Of the 1815 patients who could be interviewed, 85.7% reported at least one symptom. Before the delta variant period, 0-4 years aged children were more commonly infected, while school-aged children and adolescents were more common, and the rate of pediatric cases to all COVID-19 cases increased to 35.8% after the delta variant became dominant. Symptomatic cases were significantly higher before the delta variant (87.8% vs. 84.06%, p = 0.016). The hospitalization rate was higher before the delta variant (p < 0.001), whereas PICU admission showed no statistical difference.

CONCLUSIONS

The frequency of school-aged children and adolescents raised with the impact of both school openings and the delta variant, and the rate of pediatric cases increased in total COVID-19 patient numbers.

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 COVID-19 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.

COVID-19, Anosmia, and Allergies: Is There a Relationship? A Pediatric Perspective

Background: Between June and July 2020, we evaluated children and adolescents concerning post-infection surveillance after a COVID-19 positivity during the lockdown. We aimed to assess whether the anamnestic presence of allergies could correlate with the presence of SARS-CoV-2 symptoms, and in particular with anosmia. Material and methods: For each patient, we collected anamnestic data, the presence of allergies documented by performing skin prick tests, and COVID-19 symptoms. Then, if over six years of age, each patient underwent an active anterior rhinomanometry. Results: A total of 296 patients were enrolled, of whom 105 (35.4%) reported allergies. Considering COVID-19 symptoms, 74 subjects (25%) presented an asymptomatic form, 222 (75%) reported symptoms, and anosmia recurred in 60 subjects (27.03%). A statistically significant relationship was found between allergies and symptomatic COVID-19 (p = 0.042), allergies, and anosmia (p = 0.05), and allergies and anosmia in males (p = 0.007). Moreover, anosmic patients presented a higher body mass index, older age, and a longer COVID-19 duration with statistical significance (p = 0.001, 0.001, 0.006, respectively). Conclusions: Allergic subjects seem to develop symptomatic COVID-19 more frequently and allergies appear to be a protective factor from anosmia’s onset in males.

New views on the diagnosis and treatment of asthma in children

The medical and social significance of the problem of asthma in childhood is extremely high. Global Initiative for Asthma (GINA) for the management of this disease has been known since 1993, based on the best information available to date. Global Initiative for Asthma has now been updated — the 2022 GINA revision. GINA 2022, in particular, considers the use of a single inhaler (inhaled glucocorticoid and formoterol) both to relieve symptoms and to provide basic therapy, emphasizes the importance of having a written plan of action for asthma. Today, children with asthma are thought to have a similar risk of contracting SARS-CoV-2 as children without asthma. In the context of a coronavirus pandemic, it is essential for asthma patients to continue their proper treatment with good control of clinical symptoms. A new aspect is that when COVID-19 is confirmed or suspected, the use of nebulizers should be avoided where possible due to the risk of transmitting the infection to other patients, family members and healthcare professionals. Although spirometry monitoring is indeed an important tool, in a pandemic it is recommended to limit it to patients in whom the results of this study may affect treatment. It is important to follow the recommendations of infection control, take precautions to reduce the risk of infection. Recent developments in asthma treatment strategies offer biological drugs as an alternative. Monoclonal antibodies, drugs targeting IgE-dependent mechanisms, IL-5, IL-4, IL-13, IL-33, anti-alarmin agents, etc. are considered. The focus of special attention in the optimal use of biological therapy for asthma is proper immune endotyping, development of appropriate biomarkers, determination of the main immunological mechanism for choosing the right targeted therapy. Much attention is now being paid to the molecular aspects of asthma. In-depth knowledge of allergenic structures has led to molecular component diagnostics, which has led to a better understanding of patient sensitization. Molecular-oriented diagnostics is used to determine the best approach to allergen-specific immunotherapy.

Effects of COVID-19 lockdown on weight in a cohort of allergic children and adolescents

BACKGROUND

COVID-19 lockdown caused sudden changes in people's lifestyle, as a consequence of the forced lockdown imposed by governments all over the world. We aimed to evaluate the impact of lockdown on body mass index (BMI) in a cohort of allergic children and adolescents.

METHODS

From the first of June until the end of October 2020, we submitted a written questionnaire to all the patients who, after lockdown, carried out a visit at the Pediatric Allergy Unit of the Department of Mother-Child, Urological Science, Sapienza University of Rome. The questionnaire was composed by 10 questions, referring to the changes in their daily activities. Data were extrapolated from the questionnaire and then analyzed considering six variables: BMI before and BMI after lockdown, sugar intake, sport, screens, sleep, and anxiety.

RESULTS

One hundred fifty-three patients agreed to answer our questionnaire. Results showed a statistically significant increase in the BMI after lockdown (20.97 kg/m2 ± 2.63) with respect to the BMI before lockdown (19.18 kg/m2 ± 2.70). A multivariate regression analysis showed that the two variables that mostly influenced the increase in BMI were sleep and anxiety.

CONCLUSIONS

For the analyzed cohort of allergic children and adolescents we obtained significant gain in BMI as consequences of lockdown, which can be explained by many factors: high consumption of consolatory food, less sport activities, more time spent in front of screens, sleep alteration associated with increased anxiety. All these factors acted together, although sleep alteration and increased anxiety were the most influential factors that led to the worsening or the onset of weight gain, creating the basis for future health problems.
