“…The Olea europea sensitisation prevalence was the third most relevant (27.5 %) in this population. It was higher than in other portuguese studies 13,14,16 , but similar to studies performed in Mediterranean areas 3,29,30 . Sensitisation to Parietaria was higher (23.4 %) than in other portuguese [13][14][15] and spanish 4,29 studies, but lower than in italian studies 4,30 .…”

Parietaria is a widespread plant in the south of Europe, mainly in the coastal areas reaching the highest ratios of sensitisation, and inducing bronchial symptoms usually severe in adolescent and young adult patients.…”

Cova da Beira is an interior central region of Portugal, with a population of 93 000 inhabitants. The first pollen counts performed in Portugal revealed the highest values of the country in this area. The aim of this study was to assess the aeroallergens sensitization in an allergic population, according to the age groups. In a 5 year period (1995)(1996)(1997)(1998)(1999)(2000) 1790 consecutive outpatients were observed for suspected allergic symptoms.We included in this study all the 557 paediatric (Յ 15 years old) observed patients (317 male (57 %) and 240 female (43 %) with an average age of 7.6 Յ 4.2 years old). They were divided in three age groups (Group I: Յ 5yr; Group II: 6-10yr; Group III: 11-15yr). 371 patients were submitted to skin prick tests to aeroallergens. 86.5 % of these patients were sensitised to at least one allergen extract. The most representative aeroallergens sensitization were grasses mixture (44.9 %), D. pteronyssinus (32.5 %), D. farinae (29.1 %), Olea europea (27.5 %), Parietaria judaica (23.4 %), cat dander (16.1 %), Artemisia vulgaris (17.6 %), Robinia pseudoacacia (12.2 %), Platanus acerifolia (11.4 %), Tilia cordata (11.4 %) moulds mixture (11.2 %), Plantago lanceolata (10.6 %), dog dander (10.4 %), and Pinus radiata (7.5 %).The sensitisation to indoor aeroallergens, was similar in all age groups and it was less important than that of pollens. The prevalence of sensitisation to grasses was the greatest in all ages and the house dust mites sensitization was the second most prevalent. The highest pollens counts in this region could explain the early sensitisation even in young children.Key words: Aeroallergens. Allergic sensitisation. House dust mite. Pollens. Moulds. RESUMENCova da Beira es una región interior del centro de Portugal con una población de 93.000 habitantes. Los primeros recuentos de polen realizados en Portugal revelaron que en esta zona se hallan los valores más elevados del país. El objetivo del presente estudio fue evaluar la sensibilización a los aeroalérgenos en una población alérgica según los grupos de edad. En un período de 5 años (1995)(1996)(1997)(1998)(1999)(2000) se observaron 1.790 pacientes ambulatorios consecutivos con posibles síntomas alérgicos.En el estudio incluimos a los 557 pacientes pediá-tricos (de Յ 15 años) observados (317 niños (57 %) y 240 niñas (43 %), con una edad media de 7,6 Յ 4,2 años). Se dividieron en tres grupos de edad (grupo I: Յ 5 años; grupo II: 6-10 años; grupo III: 11-15 años).Se sometieron 371 pacientes a pruebas cutáneas con aeroalérgenos. El 86,5 % de los mismos estaban sensibilizados como mínimo a un extracto de alergeno. Los alérgenos más significativos frente a los que se observó sensibilización fueron: mezcla de hierbas (11,4 %), Tilia cordata (11,4 %), mezcla de mohos (11,2 %), Plantago lanceolata (10,6 %), caspa de perro (10,4 %) y Pinus radiata (7,5 %). La sensibilización a los aeroalérgenos domésticos fue similar en todos los grupos de edad y menos importante que la de los pólenes. La prevalencia de la se...

“…Areas of high incidence have been reported in the south of Spain, western USA, and Saudi Arabia [3, 5, 10, 11, 12, 13, 14], the pollination season lasting from June to October. In desert environments, such as Kuwait, Chenopodiaceae pollens are the main sensitizing agents among patients with allergic rhinitis or asthma with prevalence values higher than those for dusts or molds [10, 11, 12, 13].…”

Background: Pollinosis to Chenopodium album has been reported, but no data are available on its allergenic proteins. Methods: An allergen from C. album pollen has been isolated by means of gel permeation and reverse-phase high-performance liquid chromatography. Molecular characterization was achieved by concanavalin A reaction, mass spectrometry, Edman degradation and cDNA sequence. Antigenic analyses were performed by immunoblotting, ELISA, and ELISA inhibition, using sera from allergic patients, two Ole e 1-specific monoclonal antibodies and an Ole e 1-specific polyclonal antiserum. Results: The isolated allergen, Che a 1, is a glycoprotein of molecular mass 17.088 kD and 143 amino acid residues, whose sequence exhibits 27–45% identity with known members of the Ole e 1-like protein family. 77% of sera from patients allergic to chenopod pollen were reactive to Che a 1. No correlation was found between the IgE reactivities to Che a 1 and Ole e 1, the major allergens from olive pollen, and both allergens display low, although detectable, IgE and IgG cross-reactivities. Conclusions: Che a 1, a relevant allergen from chenopod pollen, is structurally related to the Ole e 1-like protein family, but exhibits significant differences on its polypeptide sequence that could explain its different antigenic behavior and limited cross-reactivity.

“…The incidence of P. lanceolata allergy has been reported in Australia (Krilis et al 1985) and in the Mediterranean area of Europe (D'Amato and Lobefalo 1989). A high prevalence of Plantago pollen has been described in Spain (Subiza et al 1995;García-González et al 1998) with percentages reaching 45 %, whereas cases of monosensitised individuals have only been described in the regions of Murcia and Castilla y León (QuirceGancedo 2005). The role of Plantago pollen in the aetiology of pollinosis has usually been overlooked in clinical practice.…”

Relationship between flowering phenology, pollen production and atmospheric pollen concentration of Plantago lanceolata (L.)

The present study sampled pollen grains in the atmosphere using a Burkard Ò 7-day-recording trap and periodically checked the flowering phases of Plantago lanceolata L. in the locality of León (NW of Spain) from late March to early August during 2007 and 2008. The results showed that the phenological phases considered for P. lanceolata coincided in most sampling points. The differences between them depended mainly on the characteristics of the land on which the plants developed and water availability. In addition, the differences between the start and duration of the different phenological phases over the 2 years were mainly due to climatic variations each year. Plantago pollen concentration in the atmosphere and phenological data were related during these 2 years of study. The differences in Plantago pollen production per anther were determined by environmental conditions such as humidity. Another important factor was human action.
