373 patients attending for routine patch testing were tested with 0.5%
and 0.05% gold sodium thiosulfate (GST). 8 (2.1%) patients had a posi
tive patch test, and a further 4 (1.0%) patient reactions which were i
nterpreted as irritant. 2 out of 8 patients with a positive patch test
to GST suspected gold allergy Frier to testing, and both of these pat
ients reported that their eczema resolved if they avoided gold jewelle
ry. This is the lowest prevalence of hypersensitivity to GST reported
and suggests that gold contact allergy may not be as widespread as has
been recently proposed. (C) Munksgaard, 1997.
