Nickel feeding in nickel-sensitive patients with hand eczema.
Ten women with vesicular hand eczema and delayed hypersensitivity to nickel were given 0.5 mg nickel supplements to their diets. The double-blind controlled supplements were given on Monday and Tuesday of each week for at least 1 month. The nickel supplement was lower than that used in previous studies, and only one subject had reproducible flaring of her vesicular dermatitis. We conclude that dietary restriction of nickel is not warranted based on nickel supplement studies, but nickel's role in hand eczema could be clarified by depleting nickel from body stores with chelating agents.
