📢 Research Alert
A recent study by Casciola et al. has provided new insights into sodium metabisulfite (SMB) — a widely used preservative included in the European Baseline Series.
Key findings from a cohort of 550 patch-tested patients:
- 2.9% showed a positive patch test to SMB.
- None of the positive reactions were considered clinically relevant.
- All SMB-positive patients tolerated intradermal testing and a local anaesthetic containing SMB without adverse reactions.
Implications:
These results suggest that while SMB positivity is relatively common, it often lacks clinical relevance and does not appear to contraindicate the use of SMB-containing local anaesthetics.

Positive Patch Test Reaction to Sodium Metabisulfite: Prevalence, Relevance and Clinical Implications

A retrospective study from Henri Mondor Hospital (Créteil, France) challenges the traditional contraindication of drug provocation testing (DPT) in DRESS.
📌 Key Takeaways:
DPT was safely performed in 52% of DRESS patients.
89% of tested drugs were ultimately authorized, including many initially contraindicated.
All reactions were mild, with no DRESS relapses.
DPTs helped avoid unnecessary contraindications.
🧠 Clinical Implication:
With expert multidisciplinary oversight, DPT can be a valuable tool in the allergological work-up of DRESS—especially when multiple drugs are suspected and treatment options are limited.

🚨 New research alert! 🚨
A study in Contact Dermatitis reveals that newer Guardian 3 and 4 glucose sensors contain multiple skin sensitizers—including 1,6-hexanediol diacrylate, isocyanates, colophonium derivatives, and acrylates—that can trigger allergic contact dermatitis in people with diabetes.
📊 In a group of patients tested, over 40% reacted to colophonium, while others showed sensitivities to isobornyl acrylate, isocyanates, and even newly identified allergens.
⚠️ While these sensors help manage diabetes, they can pose hidden skin risks. More transparency from manufacturers and continued research are urgently needed.

1,6‐Hexanediol Diacrylate, Isocyanates and Other Skin Sensitizers Are Emerging Contact Allergens in Guardian Glucose Sensors
doi.org
Allergic contact dermatitis from diabetes devices remains a significant concern. Guardian G3/4 sensors contain acrylates, colophonium, isocyanates, tert-butylphenols and many other skin sensitizers. ....🧪 Paediatric Patch Testing Practices Across Europe – New Survey
A recent ESCD Working Party survey led by Olivier Aerts highlights the variability in how children are patch tested for allergic contact dermatitis across Europe.
📊 Key findings:
No strict lower age limit – even infants may be tested when necessary
Significant differences in allergen series used, occlusion times, and reading schedules
General consensus on core procedures, but important areas of debate remain
👉 These results will guide the development of a paediatric European Baseline Series (pEBS) and future guidelines, helping to harmonise practices and improve care for children.

A new systematic review and meta-analysis by Benedikte von Spreckelsen and colleagues pulls together global data on how piercings influence the development of nickel contact allergy.
🔍 Key insights:
Piercings remain a major risk factor for nickel sensitisation.
The risk is especially high in women and in countries with weaker nickel regulation.
Even with EU nickel directives, vigilance is needed—non-compliant jewelry is still on the market.
💡 Takeaway: Nickel contact allergy is preventable. Stricter regulation and safe piercing practices could help reduce one of the most common contact allergies worldwide.

🥬 When lettuce triggers more than a rash…
A new case report by Lara Obermeyer describes a florist with chronic hand dermatitis from contact allergy to plants in the Compositae (Asteraceae) family—and a history of anaphylaxis after eating lettuce and radicchio.
🔍 Key findings:
Patch testing confirmed allergic contact dermatitis to sesquiterpene lactones in Compositae plants.
Rub tests with fresh lettuce triggered immediate wheals, supporting an IgE-mediated reaction.
No specific IgE to common food/pollen allergens was found—suggesting sensitisation to an unknown plant protein.
💡 Takeaway: Occupational skin allergies in florists may pave the way for immediate food allergies—even to plants they don’t handle daily.
