[Study on immunotherapy safety: clinical practice in allergy outpatient care].

Background: Immunotherapy with specific allergens is the only immune system-modifying treatment for allergic disease.

Objective: To identify the prevalence of adverse reactions during the subcutaneous immunotherapy initiation phase in real-life conditions and possible associated risk factors.

Methods: One-year retrospective, observational study.

Predictors of asthma relapse in patients who attended an emergency department.

Background: Patients with asthma exacerbations and frequent relapses that require admission to the emergency department (ED) often have more severe disease, worse quality of life, and higher use of health care resources.

Objective: The aim of this study was to identify potential predictors of relapse after patients are treated in an ED for an asthma exacerbation.

Methods: A retrospective, noninterventional cohort study was conducted in adult patients who attended the ED of a tertiary hospital in 2014 for an asthma exacerbation.
