Ragweed – An allergy risk in Sweden?

  title={Ragweed – An allergy risk in Sweden?},
  author={{\AA}sl{\"o}g Dahl and Sven-Olov Strandhede and J A Wihl},
Ragweed pollen, which is a major cause of allergic rhinitis in North America and during the last decades, also in parts of the European continent, has not been regarded as a risk in Sweden, since occurrences of Ambrosia have been rare and with two exceptions, ephemeral. During the last four years, however, long-distance transported pollen has been registered in South Sweden. Moreover, seeds are dispersed by man with birdseed and reports on ragweed plants growing at birdtables are becoming more…

The pollen count of ragweed was found to depend on the weather conditions, especially on wind speed and relative humidity, diversity of local flora and long distance transportation, where ragweed appeared in Europe in hitherto unknown localities.

Analysis of high allergenicity airborne pollen dispersion: common ragweed study case in Lithuania.

Analysis of the pollen data suggests that although the number of ragweed plants identified has not increased over the latter decade, the total pollen count has been on the increase during the recent period.

Ragweed pollen: The aeroallergen is spreading in Italy

This investigation aims at focusing the atmospheric concentration trend on this new aeroallergen (Ambrosia sp.) in Italy from 1991 throughout 1995 and on the increase with respect to the previous years.

Pollen‐related allergy in Europe *

Clinical and aerobiologic studies show that the pollen map of Europe is changing also as a result of cultural factors and greater international travel, and studies on allergen‐carrying paucimicronic or submicronic airborne particles, which penetrate deep into the lung, are having a relevant impact on understanding of pollinosis and its distribution throughout Europe.

Airway provocation test with ragweed pollen extract in Chinese asthmatics.

Ragweed pollen was one of the important allergens causing bronchial asthma and there was airway hyperresponsiveness to ragweed pollen in some patients (20%) with Ragweed pollenosis without asthmatic symptoms.

There are two distinct morphologic types of ragweed dermatitis, each dependent upon a different immunologic mechanism, and the typical atopic dermatitis associated with an immediate intracutaneous whealing response to the water-soluble pollen fraction, mediated through circulating serum reaginic antibody to ragweed.

[Prevalence of ragweed hayfever in the south and east of the greater Lyon region in 1993].

In 1993, AFEDA conducted an epidemiological survey in order to establish the prevalence of ragweed-induced pollinosis and to evaluate how well the public was informed about this danger, probably under-estimated this prevalence, owing to the torrential rain that fell in Lyon in late August 1993.

Ambrosia elatior (L.) in Hungary (1989–1990)

The highest percentage of airborne pollen of Ambrosia airborne pollen was found in the mid-August to mid-September period, having a good correlation with clinical data on pollinosis.
