Prognosis in nickel allergy and hand eczema

63 female patients with nickel allergy and hand eczema were reinvestigated 6 years after the primary investigation. 30% of the patients were healed. Patients with the pompholyx-type eczema had the worst prognosis. The start of hand eczema was not correlated to any particular occupation. There was a strong correlation between a history of metal sensitivity and a positive patch test reaction. High frequencies of personal and family atopy were found, and atopy made the prognosis worse. Determination of serum IgE was not found to be of any use in predicting the prognosis in patients with nickel allergy and hand eczema.
