“…in order to test whether this increase would produce an irritant response. Moreover, various titers of contact hypersensitivity to Compositae plant extract due to genuine differences, differences in extraction solvent, and qualitative and quantitative differences in the allergen content have previously been reported [33, 39]. None of 296 individuals showed any irritant reaction to ragweed extract 1% pet.…”

Background: Immunologic studies indicate that psoriasis may represent an organ-integrated response. Objective: We assessed contact hypersensitivity in plaque-type psoriasis, its frequency, etiology and association with severity of psoriasis. Methods: Contact hypersensitivity was defined as a positive patch test (PT) to at least one of 44 ubiquitous contact allergens. Patients with exclusively plaque psoriasis and control groups (patients with allergic contact or extrinsic atopic dermatitis and healthy persons) were tested with the European standard series; plant-related standard allergens; Compositae allergens, and our own extracts from Compositae plants ubiquitous in Vojvodina. Sensitization rates to allergens were standardized for age and sex, and rates in women and in men were both standardized for age. Disease severity was evaluated using the Psoriasis Area Severity Index score. Results: 15,123 PTs were performed. Among psoriatic patients in Vojvodina, the overall rate of sensitivity, standardized for age and sex, was 18.9%. Rates in women (27.7%) and men (5.8%), both standardized for age, were significantly different. Male psoriatic patients reacted less than healthy males, the difference being on the margin of significance. There was no relationship between severity of disease and PT reactivity. Yarrow extract, nickel and a Compositae mix were the most common allergens that produced positive reactions. Conclusion: Although patch testing in psoriatic patients can be quite challenging, time-consuming and difficult, it will provide further insight into the pathophysiology of psoriasis. Factors other than different exposure to allergens may also be responsible for a sex-related difference in contact sensitivity. Future studies should focus on this field.

“…Occasionally, both types of immunologic states can occur in the same individual, but, usually, there is no such correlation [5]. According to clinical experience, ragweed pollen appears to induce asthma approximately twice as often as what is usual for other pollen allergies (ie, in 40%-50% of ragweedallergic patients).…”

Weeds represent a heterogeneous group of plants, usually defined by no commercial or aesthetic value. Important allergenic weeds belong to the plant families Asteraceae, Amaranthaceae, Urticaceae, Euphorbiaceae, and Plantaginaceae. Major allergens from ragweed, mugwort, feverfew, pellitory, goosefoot, Russian thistle, plantain, and Mercurialis pollen have been characterized to varying degrees. Four major families of proteins seem to be the major cause of allergic reactions to weed pollen: the ragweed Amb a 1 family of pectate lyases; the defensin-like Art v 1 family from mugwort, feverfew, and probably also from sunflower; the Ole e 1-like allergens Pla l 1 from plantain and Che a 1 from goosefoot; and the nonspecific lipid transfer proteins Par j 1 and Par j 2 from pellitory. As described for other pollens, weed pollen also contains the panallergens profilin and calcium-binding proteins, which are responsible for extensive cross-reactivity among pollen-sensitized patients.

“…Health problems caused by A . artemisiifolia include dermatitis and eczema after direct skin contact [19], and respiratory problems and asthma due to the release of abundant quantities of highly allergenic pollen grains [3]. Moreover, the late flowering time due to its short-day plant trait extends the period of hay fever for allergy sufferers until late autumn [20, 21].…”

Phenological Variation in Ambrosia artemisiifolia L. Facilitates Near Future Establishment at Northern Latitudes

The invasive weed Ambrosia artemisiifolia (common ragweed) constitutes a great threat to public health and agriculture in large areas of the globe. Climate change, characterized by higher temperatures and prolonged vegetation periods, could increase the risk of establishment in northern Europe in the future. However, as the species is a short-day plant that requires long nights to induce bloom formation, it might still fail to produce mature seeds before the onset of winter in areas at northern latitudes characterized by short summer nights. To survey the genetic variation in flowering time and study the effect of latitudinal origin on this trait, a reciprocal common garden experiment, including eleven populations of A. artemisiifolia from Europe and North America, was conducted. The experiment was conducted both outside the range limit of the species, in Sweden and within its invaded range, in Croatia. Our main hypothesis was that the photoperiodic-thermal requirements of A. artemisiifolia constitute a barrier for reproduction at northern latitudes and, thus, halts the northern range shift despite expected climate change. Results revealed the presence of a north-south gradient in flowering time at both garden sites, indicating that certain European populations are pre-adapted to photoperiodic and thermal conditions at latitudes up to, at least, 60° N. This was confirmed by phenological recordings performed in a region close to the northern range limit, the north of Germany. Thus, we conclude that there exists a high risk for establishment and spread of A. artemisiifolia in FennoScandinavia in the near future. The range shift might occur independently of climate change, but would be accelerated by it.
