Abstract

Background:

The clinical assessment of asthma control is fundamental to evaluate the results of treatment. The Asthma Control Test (ACT) is a questionnaire with five scored items, that differentiates between a well controlled or uncontrolled asthma. It has a Spanish version and has been applied in different countries.

Aim:

To assess asthma control using the ACT and compare it with the clinical assessment of specialists in a group of pediatric patients.

Material And Methods:

The ACT was applied to 220 adolescents aged 12 to 17 years, 54% males, with persistent asthma, attended at a respiratory disease unit of a pediatric hospital. The concordance between ACT results and the assessment of specialists was also evaluated.

Results:

According to ACT and specialists, asthma was controlled in 54% and 63% of patients, respectively. There was a weak concordance between ACT and specialists assessment (Kappa index: 0.27; 95% confidence intervals: 0.14-0.4). The degree of asthma control decreased along with increasing severity of the disease (chi2 = 10.128, p =0.001).

Conclusions:

Half of the evaluated asthmatic adolescents do not have an adequate control of their disease. Severity of the disease is inversely related to the degree of control.

Asthma III: Clinical Manifestations

Asthma III: Clinical Manifestations

Asthma presents with a characteristic pattern of episodic respiratory symptoms that reflect underlying airway inflammation, bronchoconstriction, and mucus hypersecretion. Although severity varies among individuals, certain clinical manifestations are considered hallmarks of the disorder and often guide diagnosis and assessment.Respiratory SymptomsA persistent cough is one of the most common early features of asthma. It is frequently dry and tends to worsen at night or in the early morning,...

Asthma-III: Symptoms and Complications

Asthma-III: Symptoms and Complications

Asthma, a common chronic respiratory condition, is classified considering the frequency and severity of symptoms alongside lung function impairment. Understanding this classification is essential for appropriate treatment and management. Here's a detailed look at the classification of asthma and its clinical features and complications:
Classification of Asthma

Asthma: Pathogenesis and Management

Asthma: Pathogenesis and Management

Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

Asthma-II: Pathophysiology and Classification

Asthma-II: Pathophysiology and Classification

Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:
