Background: Alongside hazel, alder and birch pollen allergies, ash pollen allergy is a relevant cause of hay fever during spring in the European region. For some considerable time, ash pollen allergy was not routinely investigated and its clinical relevance may well have been underestimated, particularly since ash and birch tree pollination times are largely the same. Ash pollen extracts are no...
RATIONALE Nasal allergen provocations may be useful in investigating the pathophysiology of allergic rhinitis and effects of treatments. OBJECTIVE To use grass pollen nasal allergen challenge (NAC) to investigate the effects of allergen immunotherapy in a cross-sectional study. METHODS We studied nasal and cutaneous responses in untreated subjects with seasonal grass-pollen allergic rhiniti...
The results of our third trial on epicutaneous allergen-specific immunotherapy (EPIT) will be presented and discussed in the context of our previous trials. This monocentric, placebo-controlled, double-blind phase I/IIa trial included 98 patients with grass pollen rhinoconjunctivitis. Prior to the pollen season 2009, patients received six patches (allergen extract: n = 48; placebo: n = 50) with...
OBJECTIVE Using a model of natural allergen exposure, we examined the effect of regular treatment with salmeterol on allergen-induced changes in airway responsiveness and exhaled nitric oxide (ENO). DESIGN Double-blind, randomized, parallel-group study. SETTING Specialist allergy unit in a university hospital. PATIENTS Asthmatic patients sensitized to pollen allergens were randomly alloca...
air pollutants are reported to increase the specific ige response to allergens. to study allergen proteins and determine the effect of air pollutants on the allergenic potential of pollen extracts, the extracts were injected intraperitoneally and subcutaneously in guinea pigs. the results were analyzed by skin prick test (spt), elisa and sds-page followed by immunoblotting. the pollen extract o...
BACKGROUND Allergen exposure leads to allergen sensitization in susceptible individuals and this might influence allergic rhinitis (AR) phenotype expression. We investigated whether sensitization patterns vary in a country with subtropical and tropical regions and if sensitization patterns relate to AR phenotypes or age. METHODS In a national, cross-sectional study AR patients (2-70 y) seen b...
BACKGROUND Birch pollen is an important outdoor allergen able to aggravate symptoms in atopic dermatitis (AD). Specific immunotherapy (SIT), an established procedure for allergic airway diseases, might also represent an attractive therapeutic option for the causal treatment of allergen-triggered cutaneous symptoms in these patients. Studies with house dust mite SIT have already shown beneficial...
INTRODUCTION A pathomechanism of allergic rhinitis is complex. A neurogenic mechanism seems to play a significant role in this phenomenon. AIM The evaluation of influence of specific immunotherapy of mugwort pollen allergic patients on the bradykinin concentration in the nasal lavage fluid. MATERIAL AND METHODS The study included 22 seasonal allergic rhinitis patients. Thirty persons with m...

Anaphylactic reaction after the first dose of sublingual immuno-therapy with grass pollen tablet. Allergy. 2009;64:963--4. 5. Dunsky EH, Goldstein MF, Dvorin DJ, Belecanech GA. Anaphylaxis to sublingual immunotherapy. Allergy. 2006;6...
Allergen immunotherapy (AIT) is a guidelines-approved, disease-modifying treatment option for respiratory allergies, including allergic rhinitis (AR) induced by pollen. The various AIT regimens employed to date in pollen-induced AR can be classified as continuous (i.e. year-round) or discontinuous (i.e. pre-seasonal alone, co-seasonal alone or pre- and co-seasonal). Pre-and co-seasonal regimens...
