“…Clinically and histopathologically, psoriasis may present as different variants (6,7). Location, course and duration of lesions, itching or therapeutic resistance may suggest the involvement of an underlying trigger in the form of an irritant or a contact allergen such as tars or dithranol (4,5,(8)(9)(10). A thorough history of the patient must be taken regarding these possible factors and a relationship to particular past and current topical treatment, occupational or hobby activities responsible for cell-mediated (delayed-type) allergic immune response (DTH) must be considered.…”

“…A thorough history of the patient must be taken regarding these possible factors and a relationship to particular past and current topical treatment, occupational or hobby activities responsible for cell-mediated (delayed-type) allergic immune response (DTH) must be considered. Indepth reports on the role of DTH in psoriasis are scarce and the publications available are case reports (9)(10)(11)(12)(13). In studies on larger groups focussing on allergic contact dermatitis, mention is made of only a few psoriasis patients with contact allergy.…”

The possibility for patch testing procedures to detect contact allergy was examined in 85 hospitalized patients with forms of psoriasis. Exclusion criteria were active lesions on the back, the use of strong topical corticosteroids, methotrexate, cyclosporin and UV therapy. After screening, a group of 47 patients with different forms of psoriasis were selected for patch testing. Personal history, including topical treatment, occupation and domestic circumstances, were reasons to extend the standard series of allergens. Tars, nickel sulfate, perfume and balsam of Peru scored high. The overall positive rate was 68%. This is higher than that observed in earlier studies. The unexpected results are discussed in the light of the possible mechanism of action.

“…Although few in number, some cases of propolis allergy and contact dermatitis have been reported (Hausen et al, 1987;Hegyi et al, 1990;Silvani et al, 1997;Callejo et al, 2001), differently from the common allergy to honey, which contains allergens derived from flowers. Beekeepers usually show sensitivity to propolis (Rudeschko et al, 2004;Gulbahar et al, 2005).…”

Background:Psoriasis may be complicated by contact dermatitis due to an impaired cutaneous barrier. Patch testing helps elucidate sensitizers if any.Aims:To determine the prevalence and relevance of secondary contact dermatitis in subjects with psoriasis.Materials and Methods:Patch testing with Indian Standard Series was done and readings interpreted after 48 and 96 hours.Results:Among 110 subjects 47 (42.7%) showed reactions to at least one antigen. Fifteen (13.6%) reacted to fragrance mix, 10 (9.1%) to nickel sulfate, seven (6.4%) to parthenium, and six (5.5%) to balsam of Peru. Palmoplantar psoriasis was the commonest type of psoriasis patch tested. Fragrance mix was the commonest antigen showing 100% current relevance as an aggravating factor of psoriasis. Cosmetics, beauty preparations, skin and healthcare products followed by topical medications were found to be the most common sources of the patch test positivity.Conclusions:Secondary contact dermatitis is common in patients with psoriasis. Patch testing is necessary to determine the triggering or aggravating antigens in these patients to avoid sensitizers and improve quality of life.
