Nickel Sensitivity in Asthma Patients

Nickel sulphate frequently causes allergic contact dermatitis; less known effects are nasal inflammation (rhinitis) and bronchial asthma. In this study, we aimed to find if there is a relationship between asthma and nickel sensitivity. Asthmatic patient, non-asthmatic atopic, and healthy control groups were patch tested with nickel sulphate. Nickel sensitivity was more prevalent in the asthmatic patient group compared to the non-asthmatic atopic and healthy control groups.
