Fifty-one patients presenting a dermatological allergy (erythema, urticaria, angioedema, contact dermatitis) to nickel were treated over 3 years with oral doses of 0.1 kg nickel sulfate per day, following a low-nickel diet. Diagnostic tests comprised patch and oral provocation tests. In 7 cases, the treatment was interrupted because of symptom reactivation, and in 14 cases for other reasons. Among the 30 cases who went through the whole follow-up, symptomatology totally disappeared in 29 cases, and a partial alleviation was achieved in 1 case after 1 year of treatment. Oral provocation tests with these 30 patients showed an overall increase of tolerance. Patch tests showed no variation in 20 cases, a diminution in 5, and were negative in 5. Although the study was not conducted double blind, the results of this attempt to cure nickel allergy are statistically significant.
