A real-life comparison of the Asthma Control Test and Global Initiative for Asthma asthma control grading

The challenge of asthma control grading in clinical practice

Asthma is a chronic disease for which control is considered the management goal. However, the different methods to measure asthma control, including the Global Initiative for Asthma (GINA) criteria and Asthma Control Test (ACT), can produce conflicting results. This nationwide pediatric study compared both methods in 465 enrolled children (322 males, mean age 11.2 years). Lung function and symptom perception were also evaluated. The results showed fair concordance (k = 0.253) between GINA grading and childhood-ACT (C-ACT). Multivariate analysis revealed an association between the parents' perception of asthma and uncontrolled asthma (odds ratio [OR] = 1.52). These findings highlight the persisting puzzle of asthma control grading in primary care, which could confuse doctors. Therefore, asthma control assessment deserves adequate attention and requires substantial expertise in clinical practice.

The real-world "ControL'Asma" study: a nationwide taskforce on asthma control in children and adolescents

BACKGROUND

Asthma control is the goal of asthma management. A nationwide study on this aspect was launched by the Italian Society of Paediatric Allergy and Immunology (ControL'Asma study).

OBJECTIVE

To define variables associated with different asthma control grades in a nationwide population of asthmatic children and adolescents.

METHODS

This cross-sectional real-world study included 480 asthmatic children and adolescents (333 males, median age 11.2 years) consecutively enrolled in 10 third level pediatric allergy clinics. According to the Global Initiative for Asthma (GINA) document, history, medication use, perception of asthma symptoms assessed by visual analog scale (VAS), clinical examination, lung function, childhood asthma control test (cACT)/asthma control test (ACT), and asthma control level were evaluated.

RESULTS

Considering GINA criteria, asthma was well controlled in 55% of patients, partly controlled in 32.4%, and uncontrolled in 12.6%. Regarding cACT/ACT, asthma was uncontrolled in 23.2%. Patients with uncontrolled asthma had the lowest lung function parameters and VAS scores, more frequent bronchial obstruction and reversibility, and used more oral and inhaled corticosteroids (CS).

CONCLUSIONS

The ControL'Asma study, performed in a real-world setting, showed that asthma in Italian children and adolescents was usually more frequent in males. Asthmatic patients had an early onset and allergic phenotype with very frequent rhinitis comorbidity. Uncontrolled and partly controlled asthma affected about half of the subjects, and the assessment of asthma symptom perception by VAS could be a reliable tool in asthma management.

Asthma in children and adolescents: the ControL'Asma project

The control of asthma is the objective of asthma management. However, it is difficult to obtain in clinical practice. The Italian Society of Allergy and Clinical Immunology promoted the nationwide project "ControL'Asma" to investigate the real situation in a group of children and adolescents with asthma. The preliminary outcomes demonstrated that many asthmatic subjects do not achieve adequate asthma control. Moreover, asthma in Italian children and adolescents was usually more frequent in males, had an early onset and allergic phenotype with very frequent rhinitis comorbidity, uncontrolled and partly controlled asthma affected about the half of subjects. However, this project suggested that the assessment of asthma symptom perception by VAS could be a reliable tool in the asthma management.

Pragmatic Markers in the Management of Asthma: A Real-World-Based Approach

Bronchial hyperreactivity, reversible airflow limitation and chronic airway inflammation characterize asthma pathophysiology. Personalized medicine, i.e., a tailored management approach, is appropriate for asthma management and is based on the identification of peculiar phenotypes and endotypes. Biomarkers are necessary for defining phenotypes and endotypes. Several biomarkers have been described in asthma, but most of them are experimental and/or not commonly available. The current paper will, therefore, present pragmatic biomarkers useful for asthma management that are available in daily clinical practice. In this regard, eosinophil assessment and serum allergen-specific IgE assay are the most reliable biomarkers. Lung function, mainly concerning forced expiratory flow at 25-755 of vital capacity (FEF25-75), and nasal cytology may be envisaged as ancillary biomarkers in asthma management. In conclusion, biomarkers have clinical relevance in asthma concerning both the endotype definition and the personalization of the therapy.

The Measurement of Asthma and Allergic Rhinitis Control in Children and Adolescents

Asthma and allergic rhinitis (AR) are frequently associated. The objective of the treatment of asthma and AR should be the control of symptoms and disease progression. Therefore, the combined measurement of disease control is desirable. In this regard, a questionnaire able to together assess asthma and AR control has been validated: the CARAT (Control of Allergic Rhinitis and Asthma Test). A further pediatric version (CARATkids) has been generated. The current real-world study used different disease control measures in children and adolescents with asthma and rhinitis. A total of 138 children and adolescents were recruited at three allergy centers. CARAT, CARATkids, ACT (Asthma Control Test), cACT (children ACT), GINA (Global Initiative for Asthma) disease control classification, VAS (Visual Analog Scale) for asthma and nasal symptoms, and lung function were used in all subjects. There was a predominance of males (67.4%) and asthma was well-controlled (according to GINA classification) in about half the subjects. In children, the median CARAT and cACT values were 5 and 22 respectively. In adolescents, the median CARAT and ACT values were 23 for both tests. There were significant differences between CARAT and ACT (p = 0.035) as well as between CARATkids and cACT (p = 0.0001). However, the tests' outcomes were different as assessed in different domains. CARAT and CARATkids are disease-control measurements that give additional information to other tests, therefore, these different questionnaires to measure disease control complement each other.
