From pollinosis to digestive allergy
نویسندگان
چکیده
Pollinosis is defined as the appearance of respiratory symptoms (rhinoconjunctivitis and/or asthma) as a result of the inhalation of pollen to which the individual is sensitized. Pollen allergy becomes all the more relevant on taking into account that it may be responsible for the development of plant food allergy, or may even constitute the direct cause of esophageal, gastric and/or intestinal inflammation in the context of a digestive allergic process. Pollen can act as a source of allergens that induce primary sensitization in the host as a result of inhalation, with secondary allergy to plant foods containing shared allergens via a cross-reactivity mechanism. The observed pattern of plant food allergy depends on the dietary habits of the population in a given geographical setting, and on the pollination found in that setting. Pollinosis may account for the greater or lesser prevalence of allergy to certain plant foods, and for the severity of the associated reactions. Beyond the digestive tract inflammation that may result from allergy to a given food, pollinosis is also intrinsically able to generate a clinically relevant or irrelevant Th2-mediated inflammatory response at digestive level, and may even give rise to eosinophilic esophagitis. Inter-relation with the airway may also extend to the digestive tract as a consequence of the systemic response that characterizes allergic disease.

Cypress pollen allergy is responsible for two distinct phenotypes of allergic rhinitis different from other pollinosis.
Summary Different phenotypes of allergic rhinitis have been identified based on the seasonality of the allergen involved. Within pollinosis, importance has to be paid to the responsible pollen species. Guidelines for clinical management are mostly based on studies performed in patients with grass pollen allergy. Only few data is available on tree pollen allergy and more specifically on cypress ...
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...
متن کاملEffect of Climate Change on Fagaceae Airborne Pollen in Japan as Allergic Causative Agent Associated with Food Allergy
Rational: It is no exaggeration to say that Japanese allergic people has increased according to the increase of Japanese Cedar (JC) pollinosis since the first case report, 1964. In Japan allergenic conifer airborne pollen counts have been increasing with a concomitant change in the start of pollination as a result of climate change during about 30 years. We also investigated as if Fagaceae poll...
متن کاملOral allergy syndrome induced by tomato in a dog with Japanese cedar (Cryptomeria japonica) pollinosis.
A dog with Japanese cedar (Cryptomeria japonica, CJ) pollinosis had oral allergy syndrome (OAS) after ingesting fresh tomato. The dog showed specific IgE to both CJ and tomato allergens. As a negative control, twenty dogs without atopic dermatitis that had no exposure to tomato and no specific IgE to CJ allergen were used. They had no specific IgE to tomato allergen. Furthermore, IgE cross-reac...
