Pediatric asthma control during the COVID-19 pandemic.

BACKGROUND: The lockdown imposed by the COVID-19 pandemic resulted in a completely different style of life with possible effects on the attitude toward their disease in patients with chronic lung disease, such as asthma. The aim of our study was to investigate in asthmatic children the level of asthma control and the maintenance therapy used during the lockdown. METHODS: Among asthmatic children attending our clinic, we identified those who had been prescribed the same therapy in March-April 2019 and March-April 2020. The level of asthma control (GINA-score) and the maintenance therapy used during the lockdown (March-April 2020) were compared with those of March-April 2019. We separately analyzed a small group of children with severe asthma treated with Omalizumab during the lockdown. RESULTS: We enrolled 92 asthmatic children (67 males). Compared to 2019, in 2020 a higher proportion of children modified their maintenance therapy (38% vs. 15.2%, p < .001), with a significant increase in both the proportion of children who increased (p = .033) and in that of children who decreased their therapy (p = .026). The level of control resulted as significantly higher in 2020 (March p = .023; April p = .007). Also, the 13 children treated with Omalizumab showed a good level of control in 2020. CONCLUSIONS: In asthmatic children, the COVID-19 pandemic lockdown had a significant impact on their asthma control and on their attitude toward maintenance therapy.

How asthmatic children dealt with the coronavirus pandemia? Adherence to Controller Medications and Level of Control among Children with Asthma Registered in Mashhad University of Medical Sciences

Background: Coronavirus disease 2019 pandemic had a great effect on the lives of asthmatic children. In this study we assessed changes in medication adherence and asthma control rate among our registered children with pediatric asthma.Methods: This cross-sectional study was conducted on 113 patients registered in our asthma and allergy clinic in Mashhad, Iran. We called them via phone and completed a questionnaire on the level of asthma medication adherence and the asthma control test (ACT) before and in the 6 months after COVID-19 emergence. We investigated the changes in medication adherence and asthma control due to COVID-19 pandemic.Results: A total of 113 asthmatic children in the age range of 1 to 15 (mean, 7.02 +/- 3.24 years) were included in the study. There were zero confirmed positive cases among them since COVID-19 introduction. The minority of patients (8.8%) had weak adherence, most of the children (35.4%) completed one course of prescribed medications, 33% had longer adherence, and only 25 patients (22.1%) had full adherence during the pandemic. Overall, our patients experienced better asthma control with a 1.51 rise in ACT score to arrive in 23.64 points out of 25. They had no asthma exacerbation and emergency visit. Over half of the families compiled the national preventive measures;as 85% of children had followed the stay-at-home order during the first peak of the pandemic.Conclusion: Our patients managed to come to a higher asthma control level despite their generally decreased adherence to medications during the pandemic. COVID-19 not only could not worsen asthma status in our children but surprisingly improved it. This shows that the preventive measures should be strongly applied for the asthmatic population.

Evaluation of the effect of an education program using cartoons and comics on disease management in children with asthma: a randomized controlled study.

OBJECTIVE: The aim of this study was to determine the effect of an education program, the Health Promotion Program for Children with Asthma (HPPCA), on disease control and quality of life in children aged between 7 and 11 and diagnosed with asthma. The program was developed using cartoons and color-in materials and was based on the health promotion model developed by Nola J. Pender and brain-based learning theories. MATERIALS AND METHODS: The sample of the study consisted of 74 children between the ages of 7 and 11 who presented to the respiratory diseases' unit of a university hospital in Istanbul. All participants were given basic asthma education by their physicians, and were then randomly assigned to a group that received the HPPCA program or a control group that received no further education. After the HPPCA education was applied to the experimental group alone, both groups were administered two post-tests as a follow-up and retest at the end of the first and fourth month after the intervention. The standardized Sociodemographic Question Form, the Childhood Asthma Control Test (C-ACT) and the Pediatric Asthma Quality of Life Questionnaire (PAQLQ) were used for the follow-up. RESULTS: The asthma control and quality of life scores of the children included in the experimental group were found to be significantly higher compared to the control group at the first- and fourth-month follow-ups (p<.001). The rate of school absenteeism decreased significantly in children who received HPPCA education at the first follow-up compared to the children who did not receive the education (p<.05). PRACTICE IMPLICATIONS: The present study found that the HPPCA education, whose design was based on the health promotion model, and which was supported by cartoons in order to attract the attention of the children, was effective. The HPPCA was proven to create a sense of control over asthma and to improve the quality of life in the children. It is recommended that there be an asthma nurse in pediatric allergy and immunology outpatient clinics who can specifically provide an HPPCA. Further studies should be conducted to demonstrate the effectiveness of this program, which was examined in the present study for the first time with a randomized controlled method. HighlightsAsthma control is extremely important for the quality of life in children with asthma.Asthma education provided to school-age children yields the best results when new teaching techniques and multimedia content are used.Asthma education for children must be based on a good theoretical methodology.Children can best manage asthma when they learn about it directly.Asthma education conducted according to the guidelines is of great importance during the COVID-19 pandemic.

Changes in caregiver mental health and pediatric asthma control during COVID-19.

OBJECTIVE: This study evaluated caregivers' stress and depressive symptoms, and children's asthma control, before COVID-19 began and after its onset among families in the RVA Breathes program. METHODS: The RVA Breathes intervention, which took place in an urban city in the United States, includes asthma education delivered by a community health worker (CHW), a home assessment, and school nurse components. Participants included 125 children (5-11 years) with asthma and their caregivers (48% household income <$25,000) enrolled prior to the pandemic. Families were randomized to an active intervention arm (full intervention or intervention without school nurse component) or the control group. Caregivers completed the Center for Epidemiological Studies Depression Scale (CES-D) and the Perceived Stress Scale (PSS); children and caregivers completed the Childhood Asthma Control Test (cACT). Assessments pre-COVID-19 were compared to those completed after the pandemic's onset. RESULTS: Children in both intervention groups had better cACT scores after the start of COVID-19 compared to before (t(55) = -2.131, p = .019; t(28) = -2.893, p = .004). Caregivers in the intervention groups had lower PSS scores after the start of COVID-19 compared to pre-COVID-19 (t(53) = 3.928, p < .001; t(28) = 2.568, p = .008). Furthermore, CES-D scores improved among caregivers in the full intervention (t(48) = 1.789, p = .040). Caregivers in the control condition did not report significant changes in stress or depressive symptoms. CONCLUSIONS: Findings suggest that support from interventionists, including CHWs, might have alleviated stress and depressive symptoms during COVID-19, as well as improved asthma control during the pandemic.

Utility of biomarkers in the diagnosis and monitoring of asthmatic children.

Asthma imposes a heavy morbidity burden during childhood; it affects over 10% of children in Europe and North America and it is estimated to exceed 400 million people worldwide by the year 2025. In clinical practice, diagnosis of asthma in children is mostly based on clinical criteria; nevertheless, assessment of both physiological and pathological processes through biomarkers, support asthma diagnosis, aid monitoring, and further lead to better treatment outcomes and reduced morbidity. Recently, identification and validation of biomarkers in pediatric asthma has emerged as a top priority across leading experts, researchers, and clinicians. Moreover, the implementation of non-invasive biomarkers for the assessment and monitoring of paediatric patients with asthma, has been prioritized; however, only a proportion of them are currently included in the clinical practise. Although, the use of non-invasive biomarkers is highly supported in recent asthma guidelines for documenting diagnosis and supporting monitoring of asthmatic patients, data on the Pediatric population are limited. In the present report, the Pediatric Asthma Committee of the World Allergy Organization (WAO), aims to summarize and discuss available data for the implementation of non-invasive biomarkers in the diagnosis and monitoring in children with asthma. Information on the most studied biomarkers, including spirometry, oscillometry, markers of allergic sensitization, fractional exhaled nitric oxide, and the most recent exhaled breath markers and "omic" approaches, will be reviewed. Practical limitations and considerations based on both experts' opinion and critical review of the literature, on the utility of all "well-known" and newly introduced non-invasive biomarkers will be presented. A critical commentary on biomarkers' use in diagnosing and monitoring asthma during the COVID-19 pandemic, cost and availability of biomarkers in different settings and in developing countries, the differences on the biomarkers use between Primary Practitioners, Pediatricians, and Specialists and their role on the longitudinal aspect of asthma is provided.

Daily Associations of Air Pollution and Pediatric Asthma Risk Using the Biomedical REAI-Time Health Evaluation (BREATHE) Kit.

BACKGROUND: Exposure to air pollution is associated with acute pediatric asthma exacerbations, including reduced lung function, rescue medication usage, and increased symptoms; however, most studies are limited in investigating longitudinal changes in these acute effects. This study aims to investigate the effects of daily air pollution exposure on acute pediatric asthma exacerbation risk using a repeated-measures design. METHODS: We conducted a panel study of 40 children aged 8-16 years with moderate-to-severe asthma. We deployed the Biomedical REAI-Time Health Evaluation (BREATHE) Kit developed in the Los Angeles PRISMS Center to continuously monitor personal exposure to particulate matter of aerodynamic diameter < 2.5 µm (PM2.5), relative humidity and temperature, geolocation (GPS), and asthma outcomes including lung function, medication use, and symptoms for 14 days. Hourly ambient (PM2.5, nitrogen dioxide (NO2), ozone (O3)) and traffic-related (nitrogen oxides (NOx) and PM2.5) air pollution exposures were modeled based on location. We used mixed-effects models to examine the association of same day and lagged (up to 2 days) exposures with daily changes in % predicted forced expiratory volume in 1 s (FEV1) and % predicted peak expiratory flow (PEF), count of rescue inhaler puffs, and symptoms. RESULTS: Participants were on average 12.0 years old (range: 8.4-16.8) with mean (SD) morning %predicted FEV1 of 67.9% (17.3%) and PEF of 69.1% (18.4%) and 1.4 (3.5) puffs per day of rescue inhaler use. Participants reported chest tightness, wheeze, trouble breathing, and cough symptoms on 36.4%, 17.5%, 32.3%, and 42.9%, respectively (n = 217 person-days). One SD increase in previous day O3 exposure was associated with reduced morning (beta [95% CI]: -4.11 [-6.86, -1.36]), evening (-2.65 [-5.19, -0.10]) and daily average %predicted FEV1 (-3.45 [-6.42, -0.47]). Daily (lag 0) exposure to traffic-related PM2.5 exposure was associated with reduced morning %predicted PEF (-3.97 [-7.69, -0.26]) and greater odds of "feeling scared of trouble breathing" symptom (odds ratio [95% CI]: 1.83 [1.03, 3.24]). Exposure to ambient O3, NOx, and NO was significantly associated with increased rescue inhaler use (rate ratio [95% CI]: O3 1.52 [1.02, 2.27], NOx 1.61 [1.23, 2.11], NO 1.80 [1.37, 2.35]). CONCLUSIONS: We found significant associations of air pollution exposure with lung function, rescue inhaler use, and "feeling scared of trouble breathing." Our study demonstrates the potential of informatics and wearable sensor technologies at collecting highly resolved, contextual, and personal exposure data for understanding acute pediatric asthma triggers.

Effect of the SARS-CoV-2 pandemic on the control and severity of pediatric asthma.

BACKGROUND: The novel disease caused by the new coronavirus SARS-CoV-2 has caused an unprecedented global pandemic. Care providers of asthmatic children are increasingly con-cerned; as viral infections are one of the primary triggers of asthma flare-up. However, the effect of SARS-CoV-2 as well as the generated worldwide lockdown on asthmatic children is unknown. OBJECTIVE: The aim of this study was to analyze the effects of pandemic SARS-CoV-2 in pediat-ric asthma control. MATERIAL AND METHODS: A retrospective, open, transversal study was performed at five ter-tiary hospitals. Recruited patients were aged <18 years and had physician-diagnosed asthma. Information regarding the 2019 and 2020 seasons were provided. RESULTS: Data were collected from 107 children (age range: 3-18 years, mean age: 12 years). Well-controlled asthma was observed in 58 (54.2%) patients in 2020 versus 30 (28%) in 2019, and 15 (14%) patients had poorly controlled asthma in 2020 versus 28 (26.2%) in 2019. In 2020, a decrease in exacerbations caused by allergies to pollen, dust mites, molds, and through other causes not related to SARS-CoV-2 infection was observed. An increase in exacerbations was observed due to animal dander, stress, physical exercise, and SARSCoV-2 infection. Children had a reduced need for asthma-controlling medication, made fewer visits to healthcare providers and had lesser need of treatment with oral corticosteroids if compared with the same season of 2019. CONCLUSION: Pediatric asthma control improved, the need for controller medication declined, and fewer visits to healthcare providers were made during the pandemic if compared with the 2019 season.

Effects of the COVID-19 pandemic and lockdown on symptom control in preschool children with recurrent wheezing.

INTRODUCTION: Preschool wheezers are at high risk of recurrent attacks triggered by respiratory viruses, sometimes exacerbated by exposure to allergens and pollution. Because of the COVID-19 infection, the lockdown was introduced, but the effects on preschool wheezers are unknown. We hypothesized that there would be an improvement in outcomes during the lockdown, and these would be lost when the lockdown was eased. MATERIALS AND METHODS: Patients underwent medical visits before and after the COVID-19 lockdown. We recorded the childhood Asthma Control Test (cACT) and a clinical questionnaire. Data on symptoms, the need for medications and the use of healthcare resources were recorded. We compared these data with retrospective reports from the preceding year and prospectively acquired questionnaires after lockdown. RESULTS: We studied 85 preschool wheezers, mean age 4.9 years. During the lockdown, cACT score was significantly higher (median 25 vs. 23); families reported a dramatic drop in wheezing episodes (51 vs. none), significant reductions in the day and nighttime symptoms, including episodes of shortness of breath (p < .0001); the use of salbutamol and oral corticosteroids (OCS) dropped significantly (p < .0001) and 79 (95%) patients needed no OCS bursts during the lockdown. Finally, patients had significantly fewer extra medical examinations, as well as fewer Emergency Room visits (p < .0001). All were improved compared with the same time period from the previous year, but outcomes worsened significantly again after lockdown (cACT median: 22). CONCLUSIONS: During the national lockdown, children with persistent preschool wheeze showed a significant clinical improvement with reduction of respiratory symptoms, medication use for exacerbations, and use of healthcare resources. This trend reversed when lockdown restrictions were eased.

Transitioning Asthma Care From Adolescents to Adults: Severe Asthma Series.

Children with asthma grow to become adults with asthma. Adolescents are not simply older children and do not automatically transform into independent adults, nor do they become proficient in self-management of their condition overnight. Adolescence is a high-risk time for many people with asthma, with increased risk of asthma-related morbidity and mortality. Children with high-risk asthma attend hospital-based asthma clinics with their parents until they reach young adulthood, and parents usually take on the significant burden of disease management on behalf of their children. Once patients are transferred to adult medical teams, many will continue to have limited knowledge about their asthma, limited understanding of how to manage their symptoms and comorbidities, and limited comprehension of how and why to take their regular medication. Adolescence is a critical time of change during which young people yearn for autonomy. Effective transition gives young people the skills and knowledge necessary to manage their health independently and provides the substrate for autonomous care, the bed rock of long-term conditions. This review focuses on the challenges of adolescent health care and provides guidance on how to take a planned, patient-centered approach to ensure each transition is effective and safe.

The Impact of Coronavirus Disease 2019 on Pediatric Asthma in the United States.

The coronavirus disease 2019 (COVID-19) pandemic has caused severe economic and health impacts in the United States, and the impact is disproportionately more in socially disadvantages areas. The available data, albeit limited in children, suggest that the initial concerns of the potential of serious impact of COVID-19 illness in children with asthma are unproven so far. The reduction in asthma morbidities is due to improved adherence, COVID-19 control measures, school closures, and decreased exposure to allergens and viral infections in children. During the pandemic, asthma guidelines were updated to guide physicians in asthma care. In the face of unprecedented time, it is important to be vigilant, adhere to treatment guidelines, and implement preventive measures to eradicate the virus and improve outcomes in children with asthma.

Pediatric Asthma Management During the COVID-19 Pandemic: Results of a National Survey.

Background: During the COVID-19 pandemic specialists were concerned about how to achieve the best control of pediatric asthmatic patients. Methods: A national survey was performed. Analysis of the mean of follow-up, complementary tests, health system (public/private/both), availability of severe asthma units, and geographic location (cities with high COVID-19 prevalence vs. other cities with low prevalence). Differences were analyzed using contingency tables and Pearson's chi-squared test. Results: We obtained 95 responses, mostly from cities with a high disease prevalence (39; 52%). Only 29 (38.6%) of respondents provided care in a severe asthma unit. Severe asthmatic children were followed up mainly by telephone (68; 90.7%) and by in-person visits (32; 42.7%). Face-to-face care was less frequent in cities with a high prevalence of COVID-19 when compared with smaller cities (P = 0.044). Some of the surveyed physicians had discontinued patient follow-up as they were caring for patients with COVID-19 (7; 9.3%). Of all specialists surveyed, 45.3% did not evaluate severe asthmatic children with any means of testing. Pulmonary function tests were scarcely implemented. Blood tests were the most common test performed (45.3%). Specialists working in a severe asthma unit carried out more pulmonary function tests (P = 0.019). Peculiarly, moderate persistent asthmatics underwent more spirometries in cities with a high prevalence rate (P = 0.03). Follow-up of asthmatic children during the pandemic was perceived to be reduced or altogether inexistent by 42.7% of respondents when compared with a similar season outside of this emergency situation. Remarkably, the perception that better management of asthma was delivered during the pandemic by those working in cities with a high prevalence of COVID-19 versus other regions. Conclusions: Pediatric asthma control is crucial to decrease the future risk presented by the condition. New technologies and severe asthma units may become key tools in global health emergencies such as the COVID-19 pandemic.

Air pollution declines during COVID-19 lockdowns mitigate the global health burden.

The lockdown response to COVID-19 has resulted in an unprecedented reduction in global economic activity and associated air pollutant levels, especially from a decline in land transportation. We utilized a network of >10,000 air quality stations distributed over 34 countries during lockdown dates up until 15 May 2020 to obtain lockdown related anomalies for nitrogen dioxide, ozone and particulate matter smaller than 2.5 µm in diameter (PM2.5). Pollutant anomalies were related to short-term health outcomes using empirical exposure-response functions. We estimate that there were a net total of 49,900 (11,000 to 90,000; 95% confidence interval) excess deaths and 89,000 (64,700 to 107,000) pediatric asthma emergency room visits avoided during lockdowns. In China and India alone, the PM2.5-related avoided excess mortality was 19,600 (15,300 to 24,000) and 30,500 (5700 to 68,000), respectively. While the state of COVID-19 imposed lockdown is not sustainable, these findings illustrate the potential health benefits gained by reducing "business as usual" air pollutant emissions from economic activities primarily through finding alternative transportation solutions.
