“…An association has been noted between CAD and airborne allergy to Compositae plants. 9,10 Patient 3 in this study had CAD and an ACD reaction to a Compositae plant, T vulgare but a negative reaction to a sesquiterpene-lactone mix. Screening with the sesquiterpene-lactone and Compositae mixes may not be sufficient to thoroughly evaluate airborne allergy to plants.…”

“…The reported concentration of dandelion extract used for patch testing varies among different studies from 1 (3) to 10% pet. (8) and 10% alcohol (2, 7, 9). The recommended concentration is 2.5% pet.…”

“…Additional testing with selected weeds has recently been proposed (2), particularly with dandelion, because this has become an important allergen in its own right in SL mix‐negative patients (3–6). Testing with dandelion may detect most SL mix‐negative, Compositae‐sensitive persons (4, 5), though this may vary between different geographical regions (2, 7). The significance of the weed as a sensitizer has not been clarified, though in the majority, the positive patch tests to dandelion extract were thought to be clinically relevant (2–5, 7–10).…”

Sesquiterpene lactone mix patch testing supplemented with dandelion extract in patients with allergic contact dermatitis, atopic dermatitis and non‐allergic chronic inflammatory skin diseases

et al. 2004

We investigated the value of patch testing with dandelion (Compositae) extract in addition to sesquiterpene lactone (SL) mix in selected patients. After we detected a case of contact erythema multiforme after patch testing with dandelion and common chickweed (Caryophyllaceae), additional testing with common chickweed extract was performed. A total of 235 adults with a mean age of 52.3 years were tested. There were 66 men and 169 women: 53 consecutive patients with allergic contact dermatitis (ACD); 43 with atopic dermatitis (AD); 90 non-atopics suffering from non-allergic chronic inflammatory skin diseases; 49 healthy volunteers. All were tested with SL mix 0.1% petrolatum (pet.) and diethyl ether extracts from Taraxacum officinale (dandelion) 0.1 and 3.0% pet. and from Stellaria media (common chickweed) 0.1 and 3% pet. A total of 14 individuals (5.9%) showed allergic reaction (AR) to at least 1 of the plant allergens, 4 (28.6%) to common chickweed extract, and 11 (78.6%) to Compositae allergens. These 11 persons made the overall prevalence of 4.7%: 8 (3.4%) were SL-positive and 3 (1.3%) reacted to dandelion extract. 5 persons (45.5%) had AD, 2 had ACD, 2 had psoriasis and 2 were healthy controls. The Compositae allergy was relevant in 8 cases (72.7%). The highest frequency of SL mix sensitivity (9.3%) was among those with AD. Half the SL mix-sensitive individuals had AD. ARs to dandelion extract were obtained only among patients with eczema. A total of 9 irritant reactions (IRs) in 9 individuals (3.8%) were recorded, 8 to SL mix and 1 to common chickweed extract 3.0% pet. No IR was recorded to dandelion extract (P = 0.007). Among those with relevant Compositae allergy, 50.0% had AR to fragrance mix and balsam of Peru (Myroxylon pereirae resin) and colophonium. SLs were detected in dandelion but not in common chickweed. Our study confirmed the importance of 1 positive reaction for emerging, not fully established, Compositae allergy. In conclusion, the overall prevalence of 4.7% in our study represents a basal SL mix detection rate of 3.4% reinforced and safely supplemented by testing with the dandelion extract.

“…This are in agreement with our results, since neither photoallergic nor phototoxic PT reactions to the plants in question, including 6‐methylcoumarin, was observed. Contact allergy to dandelion may be an important part of the photosensitivity dermatitis and actinic reticuloid (PD/AR) syndrome, since 24% of the PD/AR patients showed a positive PT to dandelion oleoresin extract, and all of them reacted to SL mix (25). The phototoxic effects of Compositae plants and the difficulty in interpreting presumed positive PPT results using plant extracts in patients with persistent photosensitivity have been described, but there was no photosensitivity in our patient.…”

Erythema multiforme due to contact with weeds: a recurrence after patch testing

et al. 2003

Erythema multiforme (EM) as a complication of patch testing (PT) is rare. A 52-year-old woman with a 13-year history of episodes of EM, after contact with weeds during home gardening, had had no recent history of herpes simplex, other infection, drug ingestion or vaccination. On examination, EM lesions were distributed on the exposed skin. 5 weeks after complete resolution, PT and photopatch testing (PPT) were done with fresh plants she brought in. She was PT with a standard series and the Hermal-Trolab plants, woods, tars, balsams and flavors series. Intradermal testing, with a 3 + reaction to mixed weed pollens, was done 3 weeks later. Specific IgE to weed pollens class 1 (CAP-Pharmacia) was detected. Eczematous PT reactions were obtained with fresh leaves: common chickweed (Stellaria media Caryophyllaceae), dandelion (Taraxacum officinale Compositae), field-milk thistle (Sonchus arvensis Compositae) and white clover (Trifolium repens Leguminosae). Photoaggravation was seen to common chickweed and dandelion. Positive PT was also seen with alantolactone. By the 4-day reading, a typical EM had commenced, coming up to quite the same extent as seen on admission. There was no photosensitivity (UV skin tester, K. Waldmann). In the essential oil obtained from common chickweed, thin layer chromatography (TLC) revealed the well-known contact allergens borneol, menthol, linalool, 1,8-cineole, and other terpenes such as epoxy-dehydro-caryophyllene, monoterpene alcohol-ester and caryophyllene. Up to now, no data on essential oil in Stellaria media (common chickweed) have been reported. It can be concluded that EM developed due to contact with weeds, and recurred after patch testing. Neither blistering nor eczematous lesions have been seen on her skin, making this case very unusual. As far as the world literature is concerned, this is only the 4th report of EM developing in association with patch testing.
