Climate change is significantly altering the dynamics of airborne allergens, affecting their seasonality, allergenicity, and geographic distribution, which correlates with increasing rates of allergic diseases. This study investigates aeroallergen sensitization among populations from Tenerife, Spain, and Lima, Peru-two regions with similar climates but distinct socio-economic conditions. Our findings reveal that Spanish individuals, particularly those with asthma, demonstrate higher sensitization levels to a broader range of allergens, especially mites, with 85% of participants reacting to at least one mite allergen.

- Patch test outcomes can be affected by age, but there are mixed findings on how age impacts these results.
- The study involved over 13,000 patients and revealed that middle-aged adults (31-65 years) had the highest rates of positive skin sensitisation results, particularly for certain substances like nickel and potassium dichromate.
- Overall, while age does influence some patch test results, most allergens showed consistent reactivity across ages, underscoring the importance of standard testing regardless of age.
Background: Reports of allergic contact dermatitis (ACD) to phytonadione epoxide (PE) in cosmetics suggest that PE is as powerful a sensitiser as its parent compound phytonadione.
Objective: To evaluate a case series of ACD to PE in Spain.
Methods: We reviewed the records of 20 patients with ACD to cosmetics containing PE diagnosed across Spain between January 2019 and June 2023.
Article Synopsis
- Atopic dermatitis (AD) and allergic contact dermatitis (ACD) are different inflammatory skin conditions, and the study aimed to explore their relationship further among patients referred for patch testing.
- Researchers analyzed data from the Spanish Registry of Research in Contact Dermatitis and Cutaneous Allergy (REIDAC) to compare contact allergies and other clinical details between patients with AD and those without.
- The study found that while both groups showed similar allergy profiles, patients with AD had a lower likelihood of being sensitized to nickel sulphate compared to non-AD patients.
