||Lactase-induced occupational protein contact dermatitis and allergic rhinoconjunctivitis
||Aug. 2007, Vol.57, No.2, p.89-93. Illus. 19 ref.
||This article reports a case of protein contact dermatitis and allergic rhinoconjunctivitis from occupational exposure to lactase in a female pharmaceutical worker in Finland. The patient exhibited strong positive responses to lactase in prick tests. In an open application test, lactase elicited whealing, and in patch testing, lactase elicited an eczematous reaction. Serum lactase-specific immunoglobulin E (IgE) antibodies were demonstrated in immunospot and radioallergosorbent test assays, and lactase-IgE-binding fractions were examined in immunoblot and immunoblot inhibition assays. The chamber challenge test was performed to detect the association between lactase sensitization and rhinoconjunctival symptoms. The results confirm previous observations that lactase can induce occupational IgE- mediated respiratory and conjunctival sensitizations, but in addition show that contact skin reactions caused by lactase may also occur.
