ABSTRACT
BACKGROUND: Psoriatic arthritis (PsA) substantially impacts the management of psoriatic disease. OBJECTIVE: This study aimed to generate an interdisciplinary national consensus on recommendations of how PsA should be managed. METHODS: Based on a systematic literature search, an interdisciplinary expert group identified important domains and went through 3 rounds of a Delphi exercise, followed by a nominal group discussion to generate specific recommendations. RESULTS: A strong consensus was reached on numerous central messages regarding the impact of PsA, screening procedures, organization of the interaction between dermatologists and rheumatologists, and treatment goals. CONCLUSION: These recommendations can serve as a template for similar initiatives in other countries. At the same time, they highlight the need to take into account the impact of the respective national health care system.

We studied an acute generalized exanthematous pustulosis (AGEP) due to sulfamethoxazol in a 48-year-old woman with unusual findings in allergy testing. The histological picture provided evidence for a pustular drug eruption and leukocytoclastic vasculitis. Skin testing with sulfamethoxazol was negative for immediate-type reaction (scratch test) and delayed-type reaction (epicutaneous testing). A lymphocyte transformation test (LTT) showed a significant lymphocyte stimulation (stimulation index 5.04/2.61) toward sulfamethoxazol (200/100 mg/ml) by measuring the rate of built-in tritium-thymidine in the DNS of the patients lymphocytes, implicating a drug-specific hypersensibility of lymphocytes; we could be dealing with a combined type III and IV reaction by Coombs and Gell in this case. LTT may play a possible role in the determination of drug allergy in AGEP despite negative skin testing.

Protein contact dermatitis to meat is well known in butchers; spices are another source of potential contact allergy and usually are not recognized. We present a first case of contact-dermatitis to spice mix in a 39-year-old-butcher. The patient underwent skin prick testing (SPT) with standard allergens (ALK) and different meat and spice extracts (Stallergènes), scratch-patch testing with spice mix containing glutamate, paprika and other spices. Specific serum-IgE was measured with CAP-FEIA. SPT only showed an immediate-type sensitization to mugwort (+ +), as well as different spices (paprika +, curry +, cumin +) and camomile (+ + +). Scratch-patch tests were negative for different meat, but strongly positive for spice mix (+ + +) after 30 min (wheal and flare) and (+ +) after 48 h (infiltration and vesiculation). Two healthy controls were tested negative for spice mix used from that patient (scratch-patch). Specific IgE was slightly elevated for paprika 0.47 kU/L (CAP class 1), anise 0.43 kU/L, curry 0.36 kU/L and mugwort 3.83 kU/L. Sx1 atopy-multiscreen was 3.8 kU/L due to a sensitization to mugwort alone. The tests performed demonstrate an IgE-mediated contact allergy to spices but also a delayed type allergy to spice mix as a manifestation of the mugwort-spice syndrome in this individual. When testing for occupational dermatitis in butchers, protein contact allergy to spices must also be taken into consideration.
