METHODS AND RESULTS: Results of corneal staining, examination of skin scrapings and feces, fungal culture, CBC, and a thyroid profile (thyroxine/triiodothyronine concentrations) were negative or normal, with the exception of eosinophilia (1,040/mm3). Examination of a punch biopsy specimen of the skin indicated chronic, nonsuppurative eosinophilic dermatitis. Skin patch testing against 25 contact allergens was negative for a delayed-type hypersensitivity reaction. Allergen-specific IgE testing, using six monkey chow additives, also yielded negative results, but testing against latex revealed a strong positive result (0.74 KU/L) consistent with a latex allergy. A skin prick test performed by use of a latex supernatant revealed significant inflammation at the latex site at 72 h and one week. Vinyl gloves were substituted for latex gloves, and that resulted in a marked decrease in erythema, pruritus, and lichenification with no flares of dermatitis for four years. Repeat skin biopsy fourteen weeks after the original biopsy revealed normal epidermis; however, mild chronic active nonsuppurative, perifolliculitis persisted. CONCLUSION: Latex can induce allergic dermatitis in nonhuman primates and should be included in the differen tial diagnosis for atopic dermatitis. | lld:pubmed |
