This survey aims to analyze how adherence to treatment, using Ask-20 questionnaire and prescription count, influences level of asthma control in a sample of patients with severe and moderate-mild asthma.
Duration of illness, poor adherence to treatment, gender, smoking habit, obesity, concomitant diseases (rhinitis, sinusitis or gastroesophageal reflux) and concomitant psychiatric disorders may be responsible for an increase and perpetuation of the inflammatory response as well as a decreased response to treatment and may be easily identified clinically. PRIMARY OBJECTIVES: a) analyze how adherence to treatment, using ASK-20 questionnaire and prescription count, influences level of asthma control in a sample of patients with severe and moderate-mild asthma. SECONDARY OBJECTIVES: a) analyze the relation between the level of asthma control according to the Asthma Control Test (ACT) score and the fraction exhaled of nitric oxide (FeNO); b) analyze the relation between the level of asthma control according to the ACT score and the gender. c) analyze the relation between the level of asthma control according to the ACT score and smoking habit. d) analyze the correlation between the level of asthma control according to the ACT score and obesity. e) analyze the relation between the level of asthma control according to the ACT score and concomitant diseases (rhinitis, sinusitis or gastroesophageal reflux). f) analyze the relation between the level of asthma control according to the ACT score and concomitant psychiatric disorders. g) analyze the relation between the level of asthma control according to the ACT score and disease severity under the terms proposed by Global Initiative for Asthma (GINA). METHOD: This is a observational cross-sectional study that includes a sample made up of 50 patients with good asthma control and 50 patients with poor asthma control according to the Asthma Control Test(ACT). DEVELOPMENT OF THE STUDY After signing the informed consent, data will be collected including gender, smoking habit, alcohol consumption, environmental and employment factors, weight, height, body mass index (BMI), history of atopy, disease severity, rhinosinusitis, gastroesophageal reflux and concomitant psychiatric disorders and a standard physical examination. Measurement of asthma control with Asthma Control Test (ACT)will be performed. Then fraction exhaled of nitric oxide (FeNO)measurement and pulmonary function testing (forced spirometry and bronchodilator test) will be performed . DEVICES AND MEASUREMENTS: Clinical variables will be collected in a case report form (CRF) specially developed for the study. Functional study: The spirometry will be performed according to the recommendations of European Respiratory Society using the Jaeger Master Lab system. Bronchodilator test will be performed with albuterol and ipratropium bromide inhalation solution. FeNO levels will be measured of using the Filt's Vario analyzer which allows for bronchial or nasal tests, with a flow and volume meter Lilly-type pneumotachograph . Adherence to treatment will be assessed with the ASK-20 questionnaire and reviewing the number of prescriptions for asthma during the last 6 months.

Analyze How Adherence to Treatment Using ASK-20 Questionnaire Influences Level of Asthma Control.
The ASK-20 (Adherence Starts with Knowledge)is a brief, self-reported instrument developed to identify patient-specific barriers to medication adherence and to improve provider/patient communication about adherence. Programs incorporating a clinical assessment tool such as the ASK-20 for identifying a broad range of risk factors for nonadherence and for developing patient-specific intervention may reduce adherence barriers and improve disease control and ability to perform daily activities in patients with asthma. To gauge the overall risk of nonadherence, the total ASK-20 score was calculated,as the sum of the individual item score, ranging from 1 to 5 and therefore total ranges score from 20 (less barriers to adherence) to 100 (more barriers).
Time frame: 4 weeks
Analyze How Adherence to Treatment Using Prescription Account Influences Level of Asthma Control.
Analyze how adherence to treatment using prescription count influences level of asthma control in a sample of patients with severe and moderate-mild asthma. The second primary endpoint analyzes how adherence, using prescription counts, influences the level of asthma control. Good adherence to treatment was defined as a count of prescriptions issued by their family physician greater than 80% of the required treatment during the last 6 months. Asthma control was measured by Asthma Control Test (ACT). Bad control if ACT score \< or = 19 . Good control if ACT score \> 19.
Time frame: 4 weeks
Fraction Exhaled of Nitric Oxide (FeNO) According to Level of Asthma Control.
Analyze the relation between the level of asthma control according to the Asthma Control Test (ACT) scores and the fraction exhaled of nitric oxide (FeNO). Units FENO: ppb (parts per billion). Asthma control was measured by Asthma Control Test(ACT). Bad control if ACT score \< or = 19 . Good control if ACT score \> 19.
Time frame: 4 weeks
Gender According to Level of Asthma Control.
This platform is for informational purposes only and does not constitute medical advice. Always consult a qualified healthcare professional.
Analyze the relation between the level of asthma control according to the Asthma Control Test (ACT) scores and the gender. Asthma control was measured by Asthma Control Test(ACT). Good control if ACT score \> 19. Bad control if ACT score \< or = 19.
Time frame: 4 weeks
Smoking Habit According to Level of Asthma Control.
Analyze the relation between the level of asthma control according to the Asthma Control Test (ACT) score and smoking habit. Good control if ACT score \> 19. Bad control if ACT score \< or = 19. Patients were divided into three types: active smokers, former smokers and people who had never smoked.
Time frame: 4 weeks
Obesity According to Level of Asthma Control.
Analyze the correlation between the level of asthma control according to the Asthma Control Test (ACT) score and obesity, measured by body mass index(BMI). If BMI (18-25) = normal. If BMI (25 - 29) = overweight. If BMI \> 30 obesity. Asthma control was measured by Asthma Control test (ACT). Good control if ACT score \> 19. Bad control if ACT score \< or = 19 .
Time frame: 4 weeks
Rhinitis According to Level of Asthma Control.
Analyze the relation between the level of asthma control according to the Asthma Control Test (ACT) score and rhinitis. Asthma control was measured by Asthma Control Test (ACT).
