Abstract

After detecting erythema multiforme due to contact with weeds, dandelion (Taraxacum officinale, Compositae) and common chickweed (Stellaria media, Caryophyllaceae), which are ubiquitous plants in Vojvodina, and concerning properties of commercial screening allergens in detection of allergy to plants, we investigated contact allergy to dandelion and to common chickweed, using their extracts. Epicutaneous tests were performed using originally prepared ether extracts of these plants, 0.1% and 3% pet., in 263 individuals: 43 with extrinsic atopic dermatitis, 55 with allergic contact dermatitis, 118 with non-allergic chronic inflammatory skin diseases and 47 healthy adults. Our results have shown that testing with both extracts (both concentrations) represents a safe method, since no irritation or sensibilization occurred. The overall prevalence of allergy to dandelion extract was 1.14%, and for common chickweed extract 2.28%. Plant allergies (especially Compositae) cannot always be detected by standard screening allergens. Additional testing with dandelion extract can detect most cases, which is in agreement with our results. Isolation of essential oil from common chickweed proved the allergenic potential of this plant. The prevale...Continue Reading

Atopic Dermatitis

Atopic dermatitis is a chronic inflammatory genetically determined disease of the skin marked by increased ability to form reagin (IgE), with increased susceptibility to allergic rhinitis and asthma, and hereditary disposition to a lowered threshold for pruritus.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
