Disease relevance of Dermatitis, Photoallergic

• Efavirenz-induced photoallergic dermatitis in HIV [1].
• A 52-year-old man developed contact and photoallergic dermatitis caused by diphenhydramine hydrochloride as well as contact dermatitis from paraphenylenediamine [2].
• CONCLUSION: Relapses of photoallergic contact dermatitis in patients photoallergic to ketoprofen can be induced by ketoprofen-contaminated objects such as bandages and slippers [3].
• She had a combination of three types of hypersensitivity to chlorpromazine, ie, allergic contact dermatitis, photocontact dermatitis, and immediate allergic photosensitivity [4].
• OBJECTIVE: We sought to report on 3 cases of photoallergic contact dermatitis from ketoprofen in topical anti-inflammatory gels and on relapses of dermatitis appearing after use of ketoprofen-contaminated objects [3].

High impact information on Dermatitis, Photoallergic

• This study reports an improved experimental guinea pig model for inducing photoallergic contact dermatitis to musk ambrette [5].
• These suppressor cells are antigen specific, inhibit the induction but not the elicitation of photoallergic contact dermatitis to TCSA, and are T lymphocytes [6].
• Exposure of mice to UVB (280 to 320 nm) radiation at a site distant from that of sensitization, before CY administration and sensitization, inhibits the development of photoallergic contact dermatitis [6].
• Quinolone-photoconjugated major histocompatibility complex class II-binding peptides with lysine are antigenic for T cells mediating murine quinolone photoallergy [7].
• We have induced photoallergy in mice to systemically administered drugs, specifically sulfanilamide and chlorpromazine [8].

Chemical compound and disease context of Dermatitis, Photoallergic

• Among NSAIDs, ketoprofen is the main drug involved in this photoallergic contact dermatitis [9].
• Persistence of photosensitivity to quinidine, which is analogous to persistent light reactivity, was documented in 1 patient, and evolution from photocontact dermatitis to actinic reticuloid was observed in 2 others [10].
• Photoallergic contact dermatitis to oxybenzone [11].
• Photoallergy to benzophenone [12].
• Allergic and photoallergic dermatitis from diphenhydramine [2].

Biological context of Dermatitis, Photoallergic

• Five cases of photocontact dermatitis due to topical ketoprofen: photopatch testing and cross-reaction study [13].

Gene context of Dermatitis, Photoallergic

• CONCLUSION: It is considered that not only Th1 but also Th2 cells participate in the pathogenesis of murine photocontact dermatitis to ketoprofen [14].
• This study was conducted to investigate in vivo evaluation of protectiveness by sunscreens in the UVA range using a mouse model of contact photoallergy (CPS) to 3,3',4',5-tetrachlorosalicylanilide (TCSA) [15].

Analytical, diagnostic and therapeutic context of Dermatitis, Photoallergic

• Musk ambrette caused a high incidence of photoallergy as indicated by the severity of the skin grades as compared to a control group [16].
