Abstract
INTRODUCTION Exercise intolerance is common in chronic airway diseases (CAD), but its mechanisms are still poorly understood. The aim of this study was to evaluate exercise capacity and its association with lung function, ventilatory limitation, and ventilatory efficiency in children and adolescents with cystic fibrosis (CF) and asthma when compared to healthy controls. METHODS Cross-sectional study including patients with mild-to-moderate asthma, CF and healthy children and adolescents. Anthropometric data, lung function (spirometry) and exercise capacity (cardiopulmonary exercise testing) were evaluated. Primary outcomes were peak oxygen consumption (VO2 peak), forced expiratory volume in 1 s (FEV1 ), breathing reserve (BR), ventilatory equivalent for oxygen consumption (VE /VO2 ) and for carbon dioxide production (VE /VCO2 ), both at the ventilatory threshold (VT1 ) and peak exercise. RESULTS Mean age of 147 patients included was 11.8 ± 3.0 years. There were differences between asthmatics and CF children when compared to their healthy peers for anthropometric and lung function measurements. Asthmatics showed lower VO2 peak when compared to both healthy and CF subjects, although no differences were found between healthy and CF patients. A lower BR was found when CF patients were compared to both healthy and asthmatic. Both CF and asthmatic patients presented higher values for VE /VO2 and VE /VCO2 at VT1 when compared to healthy individuals. For both VE /VO2 and VE /VCO2 at peak exercise CF patients presented higher values when compared to their healthy peers. CONCLUSION Patients with CF achieved good exercise capacity despite low ventilatory efficiency, low BR, and reduced lung function. However, asthmatics reported reduced cardiorespiratory capacity and normal ventilatory efficiency at peak exercise. These results demonstrate differences in the mechanisms of ventilatory limitation to maximum exercise testing in children and adolescents with CAD.

Abstract
The Spanish Guideline on the Management of Asthma, better known by its acronym in Spanish GEMA, has been available for more than 20 years. Twenty-one scientific societies or related groups both from Spain and internationally have participated in the preparation and development of the updated edition of GEMA, which in fact has been currently positioned as the reference guide on asthma in the Spanish language worldwide. Its objective is to prevent and improve the clinical situation of people with asthma by increasing the knowledge of healthcare professionals involved in their care. Its purpose is to convert scientific evidence into simple and easy-to-follow practical recommendations. Therefore, it is not a monograph that brings together all the scientific knowledge about the disease, but rather a brief document with the essentials, designed to be applied quickly in routine clinical practice. The guidelines are necessarily multidisciplinary, developed to be useful and an indispensable tool for physicians of different specialties, as well as nurses and pharmacists. Probably the most outstanding aspects of the guide are the recommendations to: establish the diagnosis of asthma using a sequential algorithm based on objective diagnostic tests; the follow-up of patients, preferably based on the strategy of achieving and maintaining control of the disease; treatment according to the level of severity of asthma, using six steps from least to greatest need of pharmaceutical drugs, and the treatment algorithm for the indication of biologics in patients with severe uncontrolled asthma based on phenotypes. And now, in addition to that, there is a novelty for easy use and follow-up through a computer application based on the chatbot-type conversational artificial intelligence (ia-GEMA).

An Pediatr (Barc) 2023:S2341-2879(23)00109-6. [PMID: 37246048 DOI: 10.1016/j.anpede.2023.05.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2023] [Accepted: 04/04/2023] [Indexed: 05/30/2023] Open
Abstract
OBJECTIVE To determine the performance of spirometry and respiratory oscillometry (RO) in the prediction of severe asthma exacerbations (SAEs) in children. METHODS In a prospective study, 148 children (age 6-14 years) with asthma were assessed with RO, spirometry and a bronchodilator (BD) test. Based on the findings of spirometry and the BD test, they were classified into three phenotypes: air trapping (AT), airflow limitation (AFL) and normal. Twelve weeks later, they were re-evaluated in relation to the occurrence of SAEs. We analysed the performance of RO, spirometry and AT/AFL phenotypes for prediction of SAEs by means of positive and negative likelihood ratios, ROC curves with the corresponding areas under the curve (AUCs) and a multivariate analysis adjusted for potential confounders. RESULTS During the follow-up, 7.4% of patients had SAEs, and there were differences between phenotypes (normal, 2.4%; AFL, 17.9%; AT, 22.2%, P = .005). The best AUC corresponded to the forced expiratory flow between 25% and 75% of vital capacity (FEF25-75): 0.787; 95% confidence interval, 0.600-0.973. Other significant AUCs were those for the reactance area (AX), forced expiratory volume in the first second (FEV1), the post-BD change in forced vital capacity (FVC), and the FEV1/FVC ratio. All of the variables had a low sensitivity for prediction of SAEs. The AT phenotype had the best specificity (93.8%; 95% CI, 87.9-97.0), but the positive and negative likelihood ratios were both significant only for the FEF25-75. In the multivariate analysis, only some spirometry parameters were significative for prediction of SAEs (AT phenotype, FEF25-75 and FEV1/FVC). CONCLUSIONS Spirometry performed better than RO for prediction of SAEs in the medium term in schoolchildren with asthma.

Abstract
INTRODUCTION Socioeconomic inequality (SEI) can adversely affect asthma control. The aim of this study was to establish the association of SEI with asthma control in children and caregiver quality of life. METHODS We assessed socioeconomic status based on the area of residence, according to the at risk of poverty rate (ARPR). After stratifying the paediatric population of Castilla y León (Spain) in ARPR tertiles, we selected participants by stratified random sampling, and identified children with asthma aged 6-14 years from the health records of primary care centres. We collected data through questionnaires completed by parents. The primary outcomes were asthma control and caregiver quality of life. We assessed their association with SEI, health care quality measures and individual factors (such as parental educational attainment) by means of multivariate regression models. RESULT The ARPR tertile was not associated with asthma control, quality of life or health care quality. A medium or high maternal educational attainment was associated with a lower risk of making an unscheduled or urgent visit (OR = .50; 95% CI, .27-.95; P = .034) and paternal educational attainment was associated with a lower risk of uncontrolled asthma (OR = 0.51; 95% CI, .28-.94; P = .030). CONCLUSION In the sample under study, SEI assessed at the local level was not associated with asthma control in children. Other factors, such as parental educational attainment, may have a protective effect.

Abstract
AIM The rapid spread of a novel human coronavirus SARS-CoV-2 led to drastic measures world-wide. Most countries were forced to declare a national lockdown. We studied the effect of lockdown measures on the level of asthma control and maintenance treatment in children with recurrent wheezing and asthma during the first wave of COVID-19 in Spain. METHODS We analysed children with recurrent wheezing or asthma before and after the implementation of the lockdown, by using a questionnaire aimed to examine pre-existing respiratory disorders, step treatment and level of asthma control before/after lockdown, COVID history and laboratory testing including IgG SARS-CoV-2. RESULTS We enrolled 475 asthmatic and pre-school wheezers (60.6% males), mean age 5.6 years. There were no differences in asthma treatment comparing both periods: 81.7% maintained the same treatment (P = 0.103). According to child asthma-control questionnaire, 87.7% remained well controlled during confinement. Nearly, a third of children (34.9%) needed reliever treatment, mainly in older children. Determination of IgG SARS-CoV-2 was performed in 233 children (49.1%) of whom 17 (7.3%) tested positive. Seven patients positive to IgG SARS-CoV-2 were assisted in the emergency department and two required hospital admission. CONCLUSIONS During COVID-19 lockdown in Spain, most children with recurrent wheezing and asthma remained well controlled from their underlying disease and did not modify greatly their maintenance treatments. Unexpectedly, we also observed that those children who tested positive to SARS-CoV-2 IgG showed a significant increase in paediatric hospital admissions and attendances to urgent care settings.

Abstract
OBJECTIVE Asthma is a chronic disease that may affect physical fitness, although its primary effects on exercise capacity, muscle strength, functionality and lifestyle, in children and adolescents, are still poorly understood. This study aimed to evaluate the differences in cardiorespiratory fitness, muscle strength, lifestyle, lung function, and functionality between asthmatics with exercise symptoms and healthy children. In addition, we have analyzed the association between clinical history and the presence of asthma. STUDY DESIGN Cross-sectional study including 71 patients with a diagnosis of asthma and 71 healthy children and adolescents (7-17 years of age). Anthropometric data, clinical history, disease control, lifestyle (KIDMED and physical activity questionnaires), lung function (spirometry), exercise-induced bronchoconstriction test, aerobic fitness (cardiopulmonary exercise test), muscle strength and functionality (timed up and go; timed up and down stairs) were evaluated. RESULTS Seventy-one patients with asthma (mean age 11.5 ± 2.7) and 71 healthy subjects (mean age 10.7 ± 2.5) were included. All asthmatic children had mild to moderate and stable asthma. EIB occurred in 56.3% of asthmatic children. Lung function was significantly (p < .05) lower in the asthmatic group when compared to healthy peers, as well as the cardiorespiratory fitness, muscle strength, lifestyle and functionality. Moreover, asthmatic children were more likely to have atopic dermatitis, allergic reactions, food allergies, and a family history of asthma when compared to healthy children. CONCLUSIONS Children with mild-to-moderate asthma presenting exercise symptoms show a reduction in cardiorespiratory fitness, muscle strength, lung function, functionality, and lifestyle when compared to healthy peers. The study provides data for pediatricians to support exercise practice aiming to improve prognosis and quality of life in asthmatic children.

Abstract
OBJECTIVES Health educational interventions improve health outcomes and quality of life in children with asthma. The main purpose of this study was to evaluate the effect of an education intervention for an asthma inhaler technique during hospital admission for an asthma exacerbation. METHODS This prospective study was conducted in a pediatric hospitalization unit of a third-level hospital. Children admitted for an asthma exacerbation were eligible for inclusion. It was developed in 2 phases: during hospital admission (T1) and 1 month after discharge (T2). In the T1 phase, caregivers completed the questionnaire to assess asthma control in children (CAN questionnaire) and performed the inhaler technique, which was evaluated with a 6-step checklist. An educational intervention was performed. In the T2 phase, caregivers completed the CAN questionnaire, and the inhaler technique was reevaluated. We hypothesized that the inhaler technique improved after the implementation of an asthma education program. RESULTS A total of 101 children were included, of whom 85 completed the T2 phase (84%). At baseline, 11.8% of participants performed the inhaler technique correctly. All steps of the inhaler technique upgraded in the T2 phase significantly (P < .01), except for the step "assemble the inhaler device correctly." Former evaluation by a pediatric pneumologist was associated with a higher score in the inhaler technique in the T1 phase. The median CAN questionnaire score in the T1 phase was 8 (interquartile range 4-16), which reduced to 4 (interquartile range 1.2-6) in the T2 phase (P < .01). CONCLUSIONS The development of an educational intervention during admission improved inhaler technique as well as asthma knowledge.

Abstract
BACKGROUND Various studies have assessed omalizumab outcomes in the clinical practice setting but follow-up and/or number of patients included were limited. We aim to describe the long-term outcomes of pediatric patients with severe persistent allergic asthma receiving omalizumab in the largest real-life cohort reported to date. METHODS ANCHORS was a multicenter, observational, retrospective cohort study conducted in 25 Pediatric Allergy and Pulmonology units in Spain. We collected data of patients < 18 years and initiating omalizumab between 2006 and 2018, from the year prior to omalizumab initiation to discontinuation or last available follow-up. The primary outcome was the evolution of the annual number of moderate-to-severe exacerbations compared with the baseline period. RESULTS Of the 484 patients included, 101 (20.9%) reached 6 years of treatment. The mean ± standard deviation number of exacerbations decreased during the first year of treatment (7.9 ± 6.6 to 1.1 ± 2.0, P < .001) and remained likewise for up to 6 years. The other clinical parameters assessed also improved significantly during the first year and stabilized or continued to improve thereafter. The percentage of patients experiencing adverse events was consistently low, and the main reason for discontinuation was good disease evolution. CONCLUSION In this large, long-term, observational study, moderate-to-severe exacerbations decreased significantly from the first year of treatment with omalizumab. The beneficial effect was maintained in the long term, along with a good safety profile. Our results position omalizumab as an effective long-term treatment in pediatric patients with severe persistent allergic asthma.

Abstract
BACKGROUND Asthmatic patients may benefit from exercise training, although the effects of a combined aerobic and resistance training program are still poorly investigated in children and adolescents. OBJECTIVE To analyze the effects of a combined exercise training (resistance and aerobic) program on aerobic fitness, lung function, asthma control and quality of life in a group of mild-moderate asthmatic children with exercise symptoms. METHODS This was a 12-week randomized controlled trial including children and adolescents diagnosed with mild-moderate asthma and presenting exercise-induced symptoms. The intervention group (IG) performed the exercise training (resistance and aerobic) 3 days/week, for 60 minutes. The control group (CG) followed routine clinical orientations. The main outcomes were cardiorespiratory fitness, muscle strength, lung function, quality of life, asthma control, and functional tests after 3 months of the intervention. RESULTS Fifty-three patients (IG = 25 and CG = 28) with a mean age of 11.5 ± 2.6 years were included. No significant differences were found between groups regarding lung function, asthma control, quality of life, and functional tests. Ventilatory equivalent for oxygen consumption at ventilatory threshold (P = .025; ηp2 = 0.083), peak oxygen consumption (P = .008; ηp2 = 0.116) and test duration (P = .014; ηp2 = 0.1) presented greater improvements in the IG. In addition, improvements were observed in leg press (P < .001; ηp2 = 0.36), hamstring curl (P = .001; ηp2 = 0.217), high row (P = .003; ηp2 = .167), low row (P = .009; ηp2 = 0.128) and quadriceps leg extension (P = .015; ηp2 = 0.108) in the IG. CONCLUSION Combined exercise training (resistance and aerobic) improved cardiorespiratory fitness and muscle strength in children and adolescents with controlled asthma and exercise symptoms.

Abstract
Aim: Asthma occurs in association with allergic rhinitis. Control of Allergic Rhinitis and Asthma Test for Children (CARATKids) is a questionnaire to assess control of both diseases. The aim of this study was to assess the validity and reliability of the CARATKids in Turkish children aged 6-12 years. Methods: After a cultural adaptation process, children with asthma and allergic rhinitis were recruited. CARATKids, childhood Asthma Control Test, total nasal symptom score, visual analog scale scores for asthma and rhinitis, peak nasal inspiratory flow and peak expiratory flow values were obtained at baseline and after 4-6 weeks. The patients were classified according to the control level for asthma and rhinitis and stable/unstable groups. Discriminative properties, internal consistency, test-retest reliability, responsiveness, validity and minimal clinically important difference (MCID) were assessed. Receiver operating characteristic curve analysis was performed. Results: About 174 patients were included. The Cronbach's alpha was 0.841. Correlation coefficients between CARATKids and external measures of control were 0.42-0.77, and between the score changes of CARATKids and external measures of control it was 0.56-0.78. Guyatt's responsiveness index was -1.88, within-patient change of CARATKids score was significant. The intra-class correlation coefficient was 0.973. The MCID was 4. A cutoff score of ≤5 on the CARATKids had a sensitivity of 100% to distinguish the controlled groups according to both the GINA and ARIA. Conclusion: CARATKids is a reliable and valid tool to assess asthma and allergic rhinitis control in Turkish children. A score of ≤5 on CARATKids defines controlled disease for both diseases simultaneously.

Abstract
Introduction Differences between the opinions of patients and physicians on the impact of asthma are common. We hypothesised that patient–physician discordance may negatively affect asthma outcome. Methods A total of 2902 patients (61% women, mean age 47 years) with moderate–severe asthma and 231 physicians participated in a prospective study. At the baseline visit, data on demographics, clinical variables, degree of asthma control according to the Asthma Control Test (ACT), basic spirometry and the Hospital Anxiety and Depression Scale (HADS) were collected and an ad hoc questionnaire was completed that allowed the degree of concordance between doctors and patients to be assessed. A scheduled telephone call after 3 months was used to elicit the ACT score and the future risk of asthma. At the final visit at 6 months, the following data were recorded: ACT score, spirometry, HADS score and an ad hoc questionnaire to assess the agreement between the doctor and the patient. Changes in study variables according to patient–physician concordance or discordance were analysed. Results The rate of patient–physician discordance was 27.2%, with overestimation of disease impact by the physician in 12.3% and underestimation in 14.9%. Patient–physician opinion discordance, particularly in the case of physicians underestimating the impact of asthma, showed worse results with statistically significant differences in ACT score, a higher percentage of patients with poor asthma control and lower HADS scores. The need for hospital and emergency department admissions was also higher. Conclusion Patient–physician opinion discordance may be contributing to lower symptomatic control and increased future risk, with a higher impact when physicians underestimate the impact of asthma on their patients.

Abstract
OBJECTIVE Assess whether the Asthma, Sport and Health (ASAH) programme taught by teachers improves asthmatics' quality of life, asthma knowledge, and reduces school absenteeism. DESIGN Randomised cluster trial parallel group. PARTICIPANTS 2293 students (203 asthmatic) in the Intervention School group (IS) and 2214 in the Comparison School (CS) (224 asthmatic) belonging to primary school. INTERVENTION Implementation of the educational programme "Asthma, Sport and Health" at grade schools, taught by physical education teachers. MAIN OUTCOME Quality of life according to the Pediatric Asthma Quality of Life Questionnaire (PAQLQ). SECONDARY OUTCOMES Asthma knowledge, asthma control, school absenteeism. RESULTS After implementing the programme in the IS group, global quality of life improved significantly (p<0.001) as did their domains, symptoms (p<0.001), emotional function (p<0.001) and activity limitations (p<0.01), while in the CS group improvement was seen in global life quality (p<0.01) without any significant changes in the domains for emotional function and activity limitations. Asthma knowledge only increased in IS, among asthmatic students from 16.51 (CI 95% 16.04-16.98) to 18.16 (CI 95% 17.69-18.62) (p<0.001) and students without asthma from 15.49 (CI95% 15.36-15.63) to 17.50 (CI95% 17.36-17.64) (p<0.001). The multiple regression analysis showed that quality of life and its domains depend on asthma knowledge and above all, having well-controlled asthma. We found no decrease in school absenteeism. CONCLUSIONS The ASAH programme improved certain quality of life aspects regarding asthma (emotional function and limitation of activities) and asthma knowledge, but it failed to reduce school absenteeism NCT01607749.

Abstract
OBJECTIVES To validate the Arabic version of the Asthma Control Test (ACT) in asthmatic children in Lebanon and identify risk factors that might affect asthma control in these children. METHODS This study, conducted between December 2015 and April 2016, included 300 children. RESULTS A high Cronbach's alpha was found for the full scale (0.959). The correlation factors between each item of the ACT scale and the whole scale ranged between 0.710 and 0.775(p < 0.001 for all items). Low mother's educational level as well as the history of asthma in the mother and the father would significantly increase the risk of uncontrolled asthma (p = 0.001; Beta = 1.862; p < 0.001; Beta = 3.534; p < 0.001; Beta = 1.885respectively). Cigarette smoking during breastfeeding and waterpipe smoking by the mother during pregnancy were both significantly associated with uncontrolled asthma (p = 0.005; Beta = 2.105 and p = 0.041; Beta = 2.325 respectively). The high mother's level of education was significantly associated with more asthma control (p = 0.008; Beta = -0.715). CONCLUSION The Arabic version of the asthma control questionnaire is a valid tool to use in pediatric patients in the Lebanese population to assess asthma control. Waterpipe smoking during pregnancy and cigarette smoking during breastfeeding, as well as the lower education level are risk factors for uncontrolled asthma. Spreading awareness among health care professionals, as well as reinforcing health education seem to be an important step toward a better asthma control.

Abstract
BACKGROUND Few instruments exist to ascertain the severity of a preschool-aged child's asthma exacerbations managed at home. OBJECTIVE We sought to develop and validate a functional status instrument to assess asthma exacerbation severity in preschoolers. METHODS The parent-completed Asthma Flare-up Diary for Young Children (ADYC), which was developed systematically, comprises 17 items, each scored from 1 (best) to 7 (worst). The ADYC was completed daily from the onset of an upper respiratory tract infection (URTI) until asthma symptom resolution; the cumulative daily score was reported. The ADYC was examined for key psychometric properties in a randomized placebo-controlled trial of pre-emptive high-dose fluticasone in preschoolers with URTI-induced asthma. RESULTS In 121 children aged 2.7 ± 1.1 years (59.5% male), the ADYC's internal consistency (Cronbach α = .97), feasibility (97% completion), and test-retest reliability (r = 0.71; 95% CI, 0.59-0.80) were demonstrated. The ADYC was responsive to change between 2 consecutive days (Guyatt statistic = 0.77) with a minimal important difference of 0.22 (0.17-0.27). Of 871 episodes, the cumulative ADYC score was significantly higher during exacerbations than during URTIs (mean difference [MD], 7.6; 95% CI, 6.4-8.9) and for exacerbations with an acute-care visit (MD, 9.1; 95% CI, 7.6-10.7), systemic corticosteroids (MD, 10.1; 95% CI, 8.3-12.0), and hospitalization (MD, 6.8; 95% CI, 2.9-10.7) versus those without. In children receiving fluticasone, the ADYC score was significantly lower versus that in the placebo group (MD, 5.1; 95% CI, 1.8-8.3). CONCLUSIONS The 17-item ADYC proved feasible, responsive to day-to-day changes, and discriminative across exacerbations of different severities. In a trial testing effective therapy in preschoolers, it identified a significant reduction in asthma exacerbation severity.

Abstract
BACKGROUND The diagnosis of exercise-induced asthma or bronchospasm (EIB) is a complex dare in daily clinical practice. The consensus is that if bronchial hyper-responsiveness (BHR) is demonstrated in a patient with symptoms consistent with EIB, then that patient can be diagnosed with exercise-induced bronchospasm. The aim of this study was to determine which BHR test is the most efficient to diagnose EIB. METHODS Children under 16, without previous asthma diagnosis, or with stable asthma, complaining of asthma-like symptoms triggered by exercise were included. Bronchodilator, methacholine, mannitol, and exercise tests were performed on all patients, following established protocols. The performance of single and combined tests was determined. RESULTS Of 46 patients (median age: 12 yr, ranged 8-16 y.o.) were recruited, 30 (70%) previously diagnosed of asthma. BHR was detected in 93.47% of the children. The exercise challenge test detected BHR in 11 of 46 (23.90%) patients, bronchodilator test in 10 of 46 (21.70%), mannitol in 36 of 45 (80%) and methacholine in 41 of 45 (91.11%). The total number of patients with BHR was detected using a combination of the methacholine and mannitol tests. A combination of the methacholine test performed first, followed by the mannitol test, was able to diagnose BHR in 100% of children with lower number of tests (n = 45) than if the order was reversed (n = 50). CONCLUSIONS Methacholine and mannitol tests detect BHR in most children with suspected EIB. Bronchodilator and exercise tests show a low positivity rate. A combination of the methacholine test, followed by the mannitol test, gives the highest return to identify BHR in children for the diagnosis of EIB.

Abstract
OBJECTIVE The Childhood Asthma Control Test (c-ACT) is a validated tool for determining pediatric asthma control. However, it is not validated in the Spanish language in Spain. We evaluated the psychometric properties of the Spanish version of the Childhood Asthma Control Test (Sc-ACT) for assessing asthma control in children ages 4 to11. METHODS This national, multicentre, prospective study was conducted in Spain with asthmatic children and their caregivers. Patients were assessed at 3 visits (Baseline, 2 Weeks, and 4 Months). Clinical variables included: symptoms, exacerbations, FEV1, asthma classification, PAQLQ and PACQLQ questionnaire scores, and asthma control as perceived by physicians, patients and caregivers. The Sc-ACT feasibility, validity, reliability, and sensitivity to change were assessed. RESULTS A total of 394 children were included; mean (SD) time to complete the Sc-ACT was 5.3 (4.4) minutes. Sc-ACT score was correlated with asthma control as perceived by physician (-0.52), patient (-0.53), and caregiver (-0.51) and with the PAQLQ (0.56) and PACQLQ (0.55) scores. Sc-ACT was found to be significantly related to intensity and frequency of asthma symptoms. Cronbach alpha coefficient α was 0.81 and intraclass correlation coefficient was ≥0.85 for all of the items. The global effect size of Sc-ACT was 0.55. The cutoff point scores of 21 or higher indicated a good asthma control and their MCID was 4 points. CONCLUSION The Spanish version of the c-ACT was found to be a reliable and valid questionnaire for evaluating asthma control in Spanish-speaking children ages 4 to 11 in Spain.

Abstract
BACKGROUND Severe asthma is often poorly controlled and its prevalence in Spanish children is unknown. The aim was to determine the prevalence of difficult-to-control severe asthma in children, the agreement of asthma control between physicians and Spanish Guidelines for Asthma Management (GEMA), and the health-related quality of life (HRQoL) for children and parents. METHODS Observational, cross-sectional, two-phase, multicentre study. In the first phase, all children who attended pneumology and allergy units during a three-month period were classified according to physicians' criteria as patients with: asthma, severe asthma, or difficult-to-control severe asthma. Patients aged 6-14 years with severe asthma (difficult-to-control or controlled) were included in the second phase. RESULTS 12,376 asthmatic children were screened in the first phase. According to physicians' criteria, 8.8% (95% CI 8.3-9.3%) had severe asthma. Of these, 24.2% (95% CI, 21.7-26.8%) had difficult-to-control severe asthma. 207 patients with severe asthma (mean age 10.8 ± 2.3 years; 61.4% male; mean of 5.5 ± 3.4 years since asthma diagnosis) were included in the second phase. Compared to the patients with controlled asthma, children with difficult-to-control asthma had a higher number of exacerbations, emergency room or unscheduled primary care visits in the previous year (p<0.0001, all) and poor HRQoL (p<0.0001, both children and caregivers). 33.3% of patients with controlled asthma according to physicians' criteria were poorly controlled according to GEMA. CONCLUSIONS Around one in four asthmatic children with severe disease had difficult-to-control asthma, although one third was underestimated by physicians. Children with difficult-to-control severe asthma had a poor HRQoL that also affected their parents.

Abstract
INTRODUCTION Nitric oxide (NO) levels can be measured at proximal (maximum airway NO flux [J'aw(NO)]) and distal (alveolar NO concentration [C(ANO)]) levels. Four inflammatory patterns have been described in asthmatic individuals, although their relevance has not been well established. The objective was to determine J'aw(NO) and C(ANO) in order to establish four inflammatory categories in asthmatics. MATERIAL AND METHODS Cross-sectional study of a sample consisting of healthy and asthmatic children. Exhaled NO was determined at multiple flows. J'aw(NO) and C(ANO) were obtained according to the two-compartment model. The asthma control questionnaire (ACQ) and spirometry were administered to asthmatic children. Patients were categorized as type I (normal J'aw(NO) and C(ANO)), type II (elevated J'aw(NO) and normal C(ANO)), type III (elevated J'aw(NO) and C(ANO)) and type IV (normal J'aw(NO) and elevated C(ANO)). Correlation between FE(NO,50), J'aw(NO) and C(ANO) was analyzed using Spearman's R Correlation Test. Analysis of variance and paired comparisons were performed using the Bonferroni correction. RESULTS One hundred sixty-two children were studied, of whom 49 (32.23%) were healthy controls and 103 (67.76%) asthmatics. In the control subjects, FE(NO,50) (ppb)(median and range) was 11.5 (1.6 to 27.3), J'aw(NO) (pl/s) was 516 (98.3 to 1470) and C(ANO) (ppb) was 2.2 (0.1 to 4.5). Forty-four (42.7%) of the asthmatic participants were categorized as type I, 41 (39.8%) as type II, 14 (13.5%) as type III and 4 (3.88%) as type IV. Good correlation was observed between J'aw(NO) and FE(NO,50) (r=0.97). There was no association between J'aw(NO) and C(ANO). FEV1/FVC decreased significantly in type III (mean 79.8±7.5). Morbidity was significantly higher in types III and IV. CONCLUSIONS Normal values obtained are similar to those previously reported. Asthmatics with high C(ANO) showed higher morbidity. No correlation was found between proximal and distal inflammation.

Abstract
The measure of Quality of Life (QoL) has become one of the most important criteria used to assess the impact of chronic illness, such as asthma, on the patients daily life, in adults and children alike. The objective of our open observational study was to measure the QoL and analyze several factors that potentially affect QoL, such as symptoms and functional respiratory parameters, in a cohort of children with asthma. One hundred and twenty-seven children with asthma, 6 to 14 years of age, living in the city of Rome, were enrolled as outpatients. They were subjected to Skin Prick Tests (SPT), underwent spirometry and filled out the Pediatric Asthma Quality of Life Questionnaire (PAQLQ). One hundred and eleven children were diagnosed with intermittent asthma, 12 (10%) with mild asthma, and four with moderate persistent asthma. Ninety-six children had a positive SPT. The mean total score of QoL, obtained from the questionnaire, was 5.4 (∓1.2 SD). Two QoL groups were created. Children with total QoL score <5.5 were included in the Lower QoL score group while children with total QoL score ≥ 5.5 were included in the Higher QoL score group. Children in the Higher group and their mothers had a higher mean age, suffered from fewer asthma exacerbations during the year preceding the study, and showed a higher mean value of forced expiratory volume (FEV1) compared to the children in the Lower category. Using Logistic regression we identified the main factors that may affect QoL as FEV1, symptoms in the previous year and mothers age. QoL is correlated with the frequency of asthma exacerbations and FEV1 values. Furthermore, our research shows that a significant impairment of QoL may also occur in patients with normal lung function, pointing out the importance of evaluating QoL in all children with asthma.

Abstract
Background Nitric oxide can be measured at multiple flow rates to determine proximal (maximum airway nitric oxide flux; JawNO) and distal inflammation (alveolar nitric oxide concentration; CANO). The main aim was to study the association among symptoms, lung function, proximal (maximum airway nitric oxide flux) and distal (alveolar nitric oxide concentration) airway inflammation in asthmatic children treated and not treated with inhaled glucocorticoids. Methods A cross-sectional study with prospective data collection was carried out in a consecutive sample of girls and boys aged between 6 and 16 years with a medical diagnosis of asthma. Maximum airway nitric oxide flux and alveolar nitric oxide concentration were calculated according to the two-compartment model. In asthmatic patients, the asthma control questionnaire (CAN) was completed and forced spirometry was performed. In controls, differences between the sexes in alveolar nitric oxide concentration and maximum airway nitric oxide flux and their correlation with height were studied. The correlation among the fraction of exhaled NO at 50 ml/s (FENO50), CANO, JawNO, forced expiratory volume in 1 second (FEV1) and the CAN questionnaire was measured and the degree of agreement regarding asthma control assessment was studied using Cohen’s kappa. Results We studied 162 children; 49 healthy (group 1), 23 asthmatic participants without treatment (group 2) and 80 asthmatic patients treated with inhaled corticosteroids (group 3). CANO (ppb) was 2.2 (0.1-4.5), 3 (0.2-9.2) and 2.45 (0.1-24), respectively. JawNO (pl/s) was 516 (98.3-1470), 2356.67 (120–6110) and 1426 (156–11805), respectively. There was a strong association (r = 0.97) between FENO50 and JawNO and the degree of agreement was very good in group 2 and was good in group 3. There was no agreement or only slight agreement between the measures used to monitor asthma control (FEV1, CAN questionnaire, CANO and JawNO). Conclusions The results for CANO and JawNO in controls were similar to those found in other reports. There was no agreement or only slight agreement among the three measure instruments analyzed to assess asthma control. In our sample, no additional information was provided by CANO and JawNO.

Abstract
BACKGROUND Control of Allergic Rhinitis and Asthma Test for Children (CARATKids) is the first questionnaire that assesses simultaneously allergic rhinitis and asthma control in children. It was recently developed, but redundancy of questions and its psychometric properties were not assessed. This study aimed to (i) establish the final version of the CARATKids questionnaire and (ii) evaluate its reliability, responsiveness, cross-sectional validity, and longitudinal validity. METHODS A prospective observational study was conducted in 11 Portuguese centers. During two visits separated by 6 wk, CARATKids, visual analog scale scales and childhood asthma control test were completed, and participant's asthma and rhinitis were evaluated by his/her physician without knowing the questionnaires' results. Data-driven item reduction was conducted, and internal consistency, responsiveness analysis, and associations with external measures of disease status were assessed. RESULTS Of the 113 children included, 101 completed both visits. After item reduction, the final version of the questionnaire has 13 items, eight to be answered by the child and five by the caregiver. Its Cronbach's alpha was 0.80, the Guyatt's responsiveness index was -1.51, and a significant (p < 0.001) within-patient change of CARATKids score in clinical unstable patients was observed. Regarding cross-sectional validity, correlation coefficients of CARATKids with the external measures of control were between 0.45 and -0.69 and met the a priori predictions. In the longitudinal validity assessment, the correlation coefficients between the score changes of CARATKids and those of external measures of control ranged from 0.34 to 0.46. CONCLUSION CARATKids showed adequate psychometric properties and is ready to be used in clinical practice.

Abstract
BACKGROUND Current asthma guidelines recommend assessing the level of a patient's asthma control. Consequently, there is increasing use of asthma control as an outcome measure in clinical research studies. Several composite assessment instruments have been developed to measure asthma control. OBJECTIVE National Institutes of Health institutes and federal agencies convened an expert group to propose the most appropriate standardized composite score of asthma control instruments to be used in future asthma studies. METHODS We conducted a comprehensive search of PubMed using both the National Library of Medicine's Medical Subject Headings and key terms to identify studies that attempted to develop and/or test composite score instruments for asthma control. We classified instruments as core (required in future studies), supplemental (used according to study aims and standardized), or emerging (requiring validation and standardization). This work was discussed at a National Institutes of Health-organized workshop convened in March 2010 and finalized in September 2011. RESULTS We identified 17 composite score instruments with published validation information; all had comparable content. Eight instruments demonstrated responsiveness over time; 3 demonstrated responsiveness to treatment. A minimal clinically important difference has been established for 3 instruments. The instruments have demographic limitations; some are proprietary, and their use could be limited by cost. CONCLUSION Two asthma composite score instruments are sufficiently validated for use in adult populations, but additional research is necessary to validate their use in nonwhite populations. Gaps also exist in validating instruments for pediatric populations.

Abstract
RATIONALE Recent guidelines focus on adjusting asthma treatment to the level of asthma control. The availability of a web-based asthma control questionnaire offers the possibility to assess asthma control without the need of outpatient clinic visits. The aim of this study was to evaluate the agreement between web-based and paper-based versions of the Asthma Control Test (ACT) and Childhood Asthma Control Test (C-ACT), short-term reproducibility and satisfaction with both versions. METHODS One hundred seventy-three children with stable asthma and a normal lung function were randomized to fill in a web-based or paper-based version of the C-ACT (4-11 years) or ACT (12-18 years). According to a cross-over design, they completed the opposite version after 1 week. Reproducibility was evaluated by repeating the 2nd version (web- or paper-based) 7 days later. RESULTS Eighty-eight children filled in the C-ACT, 68 children filled in the ACT. Intraclass Correlation Coefficient (ICC) for web-based versus paper-based C-ACT was 0.81 (95% confidence interval [95% CI] 0.72-0.87). For ACT this was 0.84 (95% CI 0.76-0.90). For web-based and paper-based C-ACT the reproducibility ICC was 0.82 (95% CI 0.67-0.90) and 0.75 (95% CI 0.59-0.85), respectively. The reproducibility ICC of the ACT for web- and paper-based versions was 0.93 (95% CI 0.87-0.97) and 0.77 (95% CI 0.59-0.88), respectively. Eighty-six percent of patients preferred the web-based version. CONCLUSION The web-based version of the C-ACT and ACT is reproducible and comparable with the paper-based version in assessing asthma control. Most children and their parents prefer the web-based version.

Abstract
BACKGROUND The aim of this study was to investigate the association among a validated symptom-based questionnaire for asthma control in children (CAN), forced expiratory volume in 1 sec (FEV(1)), and fractional exhaled nitric oxide (FE(NO)). METHODS Observational cross-sectional study was performed in a consecutive sample of asthmatic children aged between 7 and 14 years old from December 2007 to February 2008. FE(NO) was measured with a portable electrochemical analyzer and forced spirometry was performed according to American Thoracic Society/European Respiratory Society. The CAN questionnaire was completed by the parents (aged <9 years old) or by the children (> or = 9 years old). The strength of the association among FEV(1), FE(NO), and CAN questionnaire was studied using Spearman's rho, and the degree of agreement for asthma control among FEV(1), FE(NO), and CAN questionnaire, with classification of these variables according to values of normality, was studied using Pearson's chi(2) test and Cohen's kappa (KC). RESULTS We studied 268 children, mean age 9.7 +/- 2.1 years. Significant correlations were found between FE(NO) and CAN (r = 0.2), between FEV(1) and CAN (r = -0.3), and between FE(NO) and FEV(1) (r = -0.12). On classifying the variables according to values of normality, no agreement was found to establish the degree of asthma control between FE(NO) and CAN (KC = 0.18, chi(2) Pearson = 9.63); between FEV(1) and CAN (KC = 0.29, chi(2) = 38.5); or between FE(NO) and FEV(1) (KC = 0.07, chi(2) = 4.9). CONCLUSIONS The association among the three measurement instruments used to assess asthma control (FEV(1), FE(NO), and CAN) was weak. These are instruments that quantify variables that influence asthma in different ways, in this sense, none can be used instead of another in asthma management although they are complementary.

Abstract
AIM Asses the feasibility of exhaled nitric oxide (FeNO) measurement in asthmatic children using a hand-held device in the primary care setting. METHODS Multicentre study performed in the paediatric clinics in seven Spanish primary health care centres. Each centre consecutively included 6-14 year-old children with doctor-diagnosed asthma. Children were asked to obtain two valid measurements of FeNO with the hand-held device NIOX MINO (Aerocrine AB, Solna, Sweden). Feasibility analysis included: (a) percentage of children able to perform the manoeuvre, (b) time required to obtain a successful determination, (c) number of attempts needed, and (d) acceptability of the technical procedure by clinical personnel involved in their guidance. RESULTS The Study enrolled 151 children. A total of 149 (98.7%) were able to perform the FeNO manoeuvre. The majority (55%) of children had previous experience of using the hand-held device. The Overall median (and Interquartile Range, IQR) of attempts needed to reach a first valid measurement was 2 (1-3) and median (IQR) of time taken was 4 min (3-5). Nurses considered the overall procedure was very easy or easy in 87.8% (teaching) and 86.5% (performing) of children. Children with previous experience performed the manoeuvre in less attempts, less time and more easily than children without experience. CONCLUSIONS Measurement of FeNO using NIOX MINO device is technically feasible and acceptable for children and staff in the clinical context of asthma management in primary health care. Previous experience had a positive, learning effect, in teaching and performing the FeNO manoeuvre.
