EtiopathogenesisThis section has been translated automatically.
Allergic substances: animal or vegetable substances, foodstuffs, cosmetics, industrial substances.
Non-allergic (toxic) substances: plant triggers (see table), caterpillar poison (especially poison of the processionary caterpillar, see below caterpillar dermatitis), jellyfish, sea anemones, insect poisons (sting and bite reactions). Histamine-liberating substances that can be found in external substances such as: caffeine, bacitracin, polymyxin, etc.
Plant triggers of contact urticaria:
- Fruits: Apple, orange, apricot, banana, pear, fig, grapefruit, plum, peach, lemon
- Vegetables: cauliflower, endive, cucumber, potato, cabbage, lettuce, carrot, corn, celery, onion
- Spices: Chilli pepper, dill, garlic, parsley, chicory
- Others: stinging nettle (see below stinging nettle urticaria), chrysanthemum, thistle, itching bean, ricinus oil, garden tulip.

Clinical featuresThis section has been translated automatically.
The clinical appearance ranges from a localised reaction (especially in the allergic form) to the development of anaphylactic shock. Typical are acute, sharply defined, itchy or burning "contact prints" caused by the triggering substances or the triggering mechanism (e.g. exposure to cold). This often results in bizarre, "inorganic" patterns on the skin. These exogenous contact patterns are easily recognizable and thus in many cases diagnostic.
- Grade 1: Localized urticaria (itching, redness, wheals) limited to the site of exposure.
- Grade 2: additionally generalized urticaria
- Grade 3: additionally rhinoconjunctivitis, bronchospasm, complaints in oropharynx and gastrointestinal tract
- Grade 4: additional anaphylactic shock.

Internal therapyThis section has been translated automatically.
In histamine-mediated forms from stage 2 glucocorticoids in high dosage such as prednisolone (e.g. Decortin H) 100-150 mg/day (rapid balancing) in combination with antihistamines such as dimetinden (e.g. Fenistil) 1-2 amp. i.v.
From stage 3 onwards, therapy appropriate to the stage, see shock, anaphylactic.
Acetylsalicylic acid (e.g. ASS) may be helpful in severe cases of the non-histamine-mediated forms.
