Zusammenfassung
Hintergrund
Patienten mit einem Ulcus cruris haben häufig Kontaktsensibilisierungen. Moderne Wundauflagen werden oft als hypoallergen proklamiert.
Ziel
Untersuchung des Sensibilisierungsspektrums von Ulkuspatienten hinsichtlich wundrelevanter Kontaktstoffe und insbesondere moderner Wundprodukte.
Material und Methoden
Es wurden 95 Patienten mit einem Ulcus cruris mit DKG-Reihen und einer Reihe häufig verwendeter Wundprodukte mittels Epikutantestung (ECT) getestet.
Ergebnisse
Mindestens eine positive ECT-Reaktion hatten 61% der Patienten. Die häufigsten Reaktionen fanden sich für tert. Butylhydrochinon, Polyvidon-Jod, Perubalsam, ein Hydrogel, Duftstoffmix I, Duftstoffmix II, Amerchol L101 und Gentamicin. Insgesamt gab es 14 Reaktionen auf Produkte der modernen Wundversorgung. Die höchsten Sensibilisierungsraten waren dabei für Hydrokolloide und Hydrogele nachweisbar. Patienten mit Sensibilisierungen gegen moderne Wundauflagen wiesen insgesamt signifikant mehr positive Testreaktionen auf.
Schlussfolgerungen
Bei Patienten mit Ulcus cruris gibt es nicht selten Sensibilisierungen gegenüber modernen Wundprodukten, v. a. Hydrogelen. Sie sollten auch in der Diagnostik berücksichtigt werden.
Abstract
Background
Patients with leg ulcers often have contact sensitizations. Modern wound care products claim low allergic potential.
Object
To analyze the patch test results in leg ulcer patients with focus on modern care wound products.
Material and Methods
95 leg ulcer patients were tested with the standard German patch test series as well as frequently used wound care products.
Results
61% of the patients had at least one positive reaction. Most frequent reactions were seen with tert-butylhydroquinone, povidone iodine, balsam of Peru, a hydrogel, fragrance mix I and II, Amerchol L101 and gentamicin. There were 14 reactions to modern wound care products with highest sensitization rates for hydrocolloids and hydrogels. Patients sensitized to wound care products had significantly more positive patch test reactions.
Conclusion
There are sensitisations against modern wound care products, especially hydrogels. That should be considered in patch test of leg ulcer patients.
