“…(Jelks 1990; Kosisky et al 2010) This confirms the observations in Figure 5 that the pollen load from trees is 5–10 times that of the grasses and weeds. The five cities studied in Figure 5 are located in the East and Mid-West of the United States.…”

A metabolomic, geographic, and seasonal analysis of the contribution of pollen-derived adenosine to allergic sensitization

Background Studies on ragweed and birch pollen extracts suggested that the adenosine content is an important factor in allergic sensitization. However, exposure levels from other pollens and considerations of geographic and seasonal factors have not been evaluated. Objective This study compared the metabolite profile of pollen species important for allergic disease, specifically measured the adenosine content, and evaluated exposure to pollen-derived adenosine. Methods An NMR metabolomics approach was used to measure metabolite concentrations in twenty-six pollen extracts. Pollen count data was analyzed from five cities to model exposure. Results A principal component analysis of the various metabolites identified by NMR showed that pollen extracts could be differentiated primarily by sugar content: glucose, fructose, sucrose, and myo-inositol. In extracts of 10 mg of pollen/ml, the adenosine was highest for grasses (45 μM) followed by trees (23 μM) and weeds (19 μM). Pollen count data showed that tree pollen was typically 5–10 times the amount of other pollens. At the daily peaks of tree, grass, and weed season the pollen-derived adenosine exposure per day is likely to only be 1.1, 0.11, and 0.12 μg, respectively. Seasonal models of pollen exposure and respiration suggest that it would be a rare event limited to tree pollen season for concentrations of pollen-derived adenosine to approach physiological levels. Conclusions Sugar content and other metabolites may be useful in classifying pollens. Unless other factors create localized exposures that are very different from these models, pollen-derived adenosine is unlikely to be a major factor in allergic sensitization.

“…Moreover, Garcia-Ortega et al have described pollinosis caused by Mercurialis anmia in Spain (14), a newly discovered allergen of the winter period. Winter pollinosis has also been reported in Texas and Florida, caused by mountain cedar (Juniperus sabinoides), a member of the Cupressaceae family (3,15,20). Winter pollinosis can, however, be encountered in northern France, as underlined by Ott et al (19) and Bessot et al (2) in Strasbourg.…”

Pollen is rarely investigated as a cause of winter respiratory symptoms. Infectious coryza and asthma are particularly common during winter, and it has been shown that environmental antigens can cause at least some cases in Paris. Recent experimental data from Calhoun et al. (1991) indicate that pollen may act synergistically with viral respiratory infections, which are particularly prevalent in winter. In the present study, we investigated, in 130 consecutive patients presenting with winter aggravation of asthma or rhinitis, winter pollinosis by skin test, radioallergosorbent test (RAST), and specific endonasal challenge test. Totals of 35, 24, and 21 patients reacted positively in skin, RAST (> 0.70 PRU/ml), and endonasal tests, respectively. Clinical features during the season established the diagnosis of winter pollinosis in 20 cases; it was due to alder pollen in 10 patients and hazel pollen in 12. The positive predictive value of the skin test was only 0.57, as compared with 0.86 for the specific endonasal test, which had a negative predictive value of 1. Our results indicate that hazel and alder pollens should be prick-tested for more often as causes of winter respiratory symptoms in Paris, even if similar manifestations were absent during previous winters, were previously present during spring or summer, or were both absent in previous winters and present in spring or summer.

“…Moreover, in states such as Florida, where the sp. P. floridiana is found, no diagnostic extract has been obtainable (47). In 1988, 13% of patients with respiratory allergy in the Southampton area (UK) were reported to be skin-positive to Parietaria (46).…”

Species of the getius Parietaria (pellitory) are a prevalent cause of allergy in the Mediterranean area and the tiiost important in sotne European regions such as southern Italy and coastal Spain (14,26,27,29,30,31,36,59, 69). Up to now, however, Parietaria has received little attention in northern Europe and the US because of its litnited regional distribution. Therefore, less is known about Parietaria allergy than about other inhalant allergens such as those of grasses, ragweed, and mites.During the last 5 years, only 31 reports on Parietaria allergy have appeared in the literature, as compared with 37 papers on birch pollen. This ratio may appear unbalanced, considering that millions of people suffer frotn pollinosis caused by Parietaria, while a much smaller number have rhinitis and/or asthtna caused by birch pollen.The increasing movement of people throughout Europe and to and from the US is reason to broaden our knowledge of patterns of inhalant allergy in each geographic area, especially where tourism and itnmigration are high.This paper briefly reviews available data and personal studies on the botanical, aerobiological, itnmunochetnical, and clinical features o^ Parietaria allergy.
