Evaluation of birch pollen sensitization profile in allergic rhinoconjunctivitis patients from Bucharest region using component-resolved diagnosis

چکیده
Background In the Romanian flora, several species of the Betula genus are present, especially European white birch (B. pendula, syn. B. verrucosa) and downy birch (B. pubescens, syn. B. alba). Rare species are B. nana and B. humilis. In Southern Romania, the sensitization to Betulaceae pollen in patients with allergic rhinitis is less frequent than that to Poaceae pollen. The flowering season of the birch trees starts mostly in early April and lasts until mid of May, while the grass flowering period starts in May and finishes at the mid of July.

BACKGROUND Grass pollen, in particular from Lolium multiflorum is a major allergen source in temperate climate zones of Southern Brazil. The IgE sensitization profile of Brazilian grass pollen allergic patients to individual allergen molecules has not been analyzed yet. OBJECTIVE To analyze the IgE sensitization profile of a Brazilian grass pollen allergic population using individual allergen...

Methods We evaluated subjects from Southern Romania, a Central European region with temperate continental climate with submediterranean and humid subtropical influences, where sensitization to Betulaceae pollen is less important in pollinosis compared with that to grass or weed pollen. We selected adult patients from the region of sylvosteppe with low density forests dominated by deciduous spec...
متن کاملUnderstanding patient sensitization profiles in complex pollen areas: a molecular epidemiological study.
BACKGROUND Allergy diagnosis in patients exposed to multiple pollen species is complex and misdiagnosis is often a cause for unsuccessful specific immunotherapy. OBJECTIVE We studied the sensitization profile of individual allergens (major, minor and pan-allergens) in pollen-sensitized patients in a region with high exposure to olive pollen by investigating the influence of minor allergens on...

Background The high frequency of pollen sensitization has been reported among peanut and tree nuts sensitized patients in our previous study. The antigen homology of peanut and tree nuts antigens with betula was previously shown. However there is a lack of knowledge about the cross-reactivity between hazelnut and grass pollen antigens. The aim of this study is to find out if there is a differen...

BACKGROUND Allergic rhinoconjunctivitis (ARC) due to birch pollen is a growing health concern in Europe. Here, we report the efficacy and safety of 300IR birch pollen sublingual solution administered discontinuously for 2 consecutive years to patients with birch-associated allergic rhinoconjunctivitis. METHODS Birch pollen-allergic adults were randomized in this double blind study to 300IR bi...
