Venom immunotherapy (VIT) protects up to 98% of treated Hymenoptera allergy patients from reactions with new stings. A correct diagnosis with the identification of the venom causing the allergic reaction is essential to implementing it. The knowledge of the Hymenoptera foraging habits when the sting takes place in a food environment would allow the culprit insect to be known.

Objective: The objective of this study was to list the social vespids occurring in Spain, determine their presence in each region, and correlate the data with the vespids responsible for allergic reactions and their progression over time.
Methods: Insects distribution data were collected in two phases: from the southern half of Spain (2008-2012), and from the northern half of Spain (2016-2019). Data for the vespids were collected from the prescriptions of Hymenoptera venom immunotherapy (HVIT) at six Spanish hospitals in the years 2009 and 2019.
Article Synopsis
- The study focused on identifying factors that contribute to the failure of asthma treatment step-down in patients with moderate to severe asthma who were on a combination therapy of inhaled glucocorticoids and long-acting beta agonists.
- Results showed that 41.7% of patients experienced step-down failure, with significant factors including older age, multiple comorbidities, severity of asthma, and a short duration of previous asthma control.
- The conclusion emphasizes that successful step-down is more likely when patients have maintained asthma control for over 6 months, suggesting that careful consideration is needed before adjusting treatment.
Background: The minimum controlling dose of treatment must be established in patients with asthma, but the outcome of step-down is unpredictable.
Objective: To identify factors associated with risk of control loss when stepping down asthma treatment and to develop a score to predict this risk.
Methods: A prospective, multicenter study including adults with well-controlled asthma was performed.
Background: Seafood allergy has been related to mite sensitization, mainly mediated by the muscle protein tropomyosin.
Objectives: To determine the correlation between seafood hypersensitivity and mite sensitization (Dermatophagoides pteronyssinus and Chortoglyphus arcuatus, a highly prevalent storage mite in Spain) and to investigate the implication of tropomyosin in cross-reactivity.
Methods: Patients from Northwest Spain were divided into 2 groups.
Background: Chortoglyphus arcuatus has been described in many countries. Many allergens are potent enzymes, which may promote a Th2 immune response. The aim of this study was to evaluate the enzymatic activity of body and fecal extracts of C.

Objectives: To describe 2 patients with occupational roe deer allergy, demonstrated by positive skin and conjunctival provocation test results, and to note cross-reactions to other animal (mainly cow) allergens.
Methods: Two workers at animal rehabilitation centers were sensitized to roe deer.

Background: Chortoglyphus arcuatus is frequently identified in mattress dust samples in coastal areas of northern Spain.
Objectives: To establish the prevalence of positive skin test reactions to C. arcuatus and to analyze its allergenicity and cross-reactivity.
