Background. Beta-lactams (BLs) allergy is considered a major health issue, as BLs are the most frequently involved in drug allergic reactions. Amoxicillin (AX) is the main sensitizer among all BLs. AX is commercialized alone or combined with clavulanic acid (CLA) in order to increase the antibiotic spectrum. The growing prescriptions of AX-CLA formulations contributed to […]

Background. Local Allergic Rhinitis (LAR) is a phenotype defined by rhinitis symptoms with negative responses to systemic sensitization tests but with an exclusively nasal allergic inflammatory response. Data on the pediatric age group is scarce, and no Latin American data has been published so far. Methods. Nasal Allergen Challenge (NAC) was performed with Dermatophagoides pteronyssinus […]

Background. Common Variable Immunodeficiency (CVID) is a primary immunodeficiency disorder characterized by B-cell dysfunction and immunoglobulin production deficiency. Dysregulation of interleukin-17 (IL-17) and its receptor IL-17RA have been reported in various immune disorders. This study aimed to investigate the expression of IL-17RA in innate immune cells of CVID patients and its correlation with clinical manifestations. […]

Background. Atopic dermatitis is a prevalent condition in the pediatric population, with affected children exhibiting a susceptibility to cutaneous sensitization due to skin barrier dysfunction and immune dysregulation. Recent studies have highlighted an increased prevalence of certain allergens, which identification may be clinically relevant, with direct implications for the management of atopic dermatitis. Methods. We retrospective reviewed pediatric […]
Background. International guidelines suggested skin tests with Polyethylene-glycol (PEG) and polysorbate 80 (PS-80), to investigate a possible hypersensitivity to these excipients either to identify subjects at risk of developing allergic reactions to COVID-19 vaccines, or in patients with suspected IgE mediated hypersensitivity reactions (HR) to the COVID-19 vaccine. The main purpose of this study was to […]

Background. Asthma control can be influenced by several factors, including obstructive sleep apnea (OSA). The literature reports variable prevalence and magnitude of OSA impact on asthma outcomes. The aim of our study is to analyze the frequency of high-risk for OSA in asthma patients and its impact on disease severity and control. Methods. We conducted […]

Background. Allergic bronchopulmonary aspergillosis (ABPA) is an endotype of severe asthma which frequently needs biologics for their steroid sparing effect. We aimed to evaluate the outcomes of reducing the omalizumab dose in patients with ABPA who were on long-term omalizumab treatment. Methods. Once asthma was controlled, two approaches were used to reduce total monthly omalizumab dose, […]

Background. Food allergy (FA) negatively affects health-related quality of life (HR-QoL) of children and caregivers. To date, no questionnaire self-compiling assessing the HR-QoL in pre-school children with FA is available. The aim of this study is to develop and validate a self-administered, rapid and easy questionnaire to evaluate the HR-QoL in children ≥ 7 […]
Background. Due to similarities between the pathophysiological mechanisms of hereditary angioedema (HAE) and COVID-19, it has been hypothesized that SARS-CoV-2 infection may trigger HAE attacks or, alternatively, that HAE patients may experience different of COVID-19 disease severity. Furthermore, the potential for COVID-19 vaccination to trigger angioedema attacks in patients with HAE is still not completely […]

Background. Patients with autoimmune forms of chronic spontaneous urticaria (aiCSU) exhibit autoantibodies against the high-affinity IgE receptor (FcεRI) and IgE. As the presence of these autoantibodies does not correlate with disease activity, the functional affinity/avidity may be relevant in aiCSU. This exploratory study aimed to characterize the quantity and avidity of autoantibodies against IgE and […]
