Outcomes and Timepoint

Section to complete information about primary and secondary outcomes including. It includes the metric or method of measurement used and, the time point for every outcome.

Primary outcome(s):

1. Symptom score: Dyspnea, cough, expectoration, wheeze and tightness (four-digit score: 0 = non symptom, 1 = mild, 2 = moderate, 3 = severe). Measuring time: pre-treatment, and day 42, 3, 8 and 14 months. 2. Consumption of medications (three-digit score: 0= no use, 1= use beta-2 agonists, metilxantine, ephedrine, adrenaline, 2 = corticosteroids). Measuring time: pre-treatment, and day 42, 3, 8 and 14 months.

Key secondary outcomes:

1. Expiratory lung function (spirometer forced technique with portable spirometer (DATOSPIR-70). Determine the Forced Vital Capacity (FVC), and Forced Expiratory Volume in one second (FEV1). Both are expressed as a percentage of the theoretical reference value calculated according to body weight of the patient). Measuring time: pre-treatment, 42 days, 3, 8, and 14 months. 2. Skin reactivity: (value Ch10: relative allergen concentration causing in the patient a similar wheal to induced wheal by a HCL histamine solution (10 mg/mL= 54.3 mmol/L de Histamina base)). Measuring time: pre-treatment, 42 days, 3, 8, and 14 months. 3. Quality of life (Asthma Questionnaire Life Quality (Juniper)). Measuring time: Pretreatment and 3, 8, and 14 months. 4. Allergen-specific antibodies (antibody titer determination and IgG4 serum allergen-specific IgE in patients using an indirect ELISA). Measuring time: pre-treatment, 42 days, 3, 8, and 14 months. 5. Adverse events-AE (- Occurrence of some AE in the patient (Yes, No); - Description of the AE (Name of adverse event); - According to available previous information (Unexpected, Expected); - According to its localization the expected AE (World Allergy Organization Criterion: local and systemic AE (0= Nonspecific Symptoms, I= Mild systemic reactions, II= Moderate systemic reactions, III= Severe (nonlife-threatening) systemic reactions, IV= Anaphylactic shock)); - Duration of the AE (Difference of dates between star and stop of event);- Intensity of the AE (Light, Moderate, Severe); - Seriousness of the AE (Serious, No serious); - Attitude regarding the treatment in study (No changes, Dose modification, Temporary interruption, Definitive interruption of the treatment in study); - Result of the AE (Recovered, Improved, Persists, Sequels); - Causality Relationship (1.Very likely, 2.Likely, 3.Possible, 4.Unlikely, 5.Not related, 6.Not evaluated)). Measuring time: days 0, 14, 28, 42, 56, months 3, 5, 7, 8, 10, 12 and 14.
