Contact Dermatitis Clinical Trial
Official title:
Children With Aluminium Contact Allergy: Cutaneous Exposure Study
Aluminium is used in many different cosmetic products, including make-up, deodorants and sunscreen. The purpose of this study is to investigate whether these everyday skin products with small amounts of aluminium can cause skin reactions in children diagnosed with contact allergy to aluminium. The study is conducted as a Repeated Open Application Test study (ROAT), a method originally developed to clarify the clinical relevance of questionable and positive patch samples, by imitating everyday use of a skin product.
The study is conducted as a Repeated Open Application Test study (ROAT), a method originally developed to clarify the clinical relevance of questionable and positive patch samples, by imitating everyday use of a skin product. The skin products will consist of ordinary sunscreens with and without aluminium, with colour code red and blue, respectively (masked for both investigator and participants). At the beginning of the trial, the study participants will be given the two creams. On the lower back of the children, two areas each 10 cm2 are marked with red and blue, respectively. In each area, sunscreen corresponding to the generally recommended amounts must be applied twice a day. The children should be seen on day 0 for interviews and objective examination. They must then be seen again on day 7 and day 14. On day 14 of the ROAT, a patch test is made to validate the results of the ROAT study. The study is scheduled to last for a maximum of 21 days with 4-5 consultations per child. If there is a skin reaction in connection with the ROAT study before the 14 days have elapsed, the study will end and a patch test will be performed. ;
