Background. Some hemostatic disturbances are observed in patients with various clinical manifestations of atopy. Increased platelet activation in vivo has been shown in patients with chronic allergic asthma. Objectives. Investigation of selected parameters of platelet activity and fibrinolysis in patients with pollen allergy suffering from seasonal allergic rhinitis and concomitant asthma sympt...
Background Allergic rhinitis is one of the most common types of rhinitis. Allergen avoidance is the most important way of preventing this disease. The present study is carried out to determine the frequency of common aeroallergens in patients with allergic rhinitis in Gorgan city by skin prick test (SPT) reactivity. Materials and Methods In this cross-sectional study 270 patients referring t...
Seasonal pollen allergies affect approximately 1 in 5 school age children. Clinical research has established that these allergies result in large and consistent decrements in cognitive functioning, problem solving ability and speed, focus and energy. However, compared to air pollution, the impact of pollen and seasonal allergies on achievement in schools has received less attention from economi...
Patients with grass pollen allergy, commonly called pollinosis, often present reactivity to pollen allergens from a number of grass species due to cross-reactivity of IgE antibodies to pollen proteins present in pollen grasses. In this context, Italian rye grass (Lolium multiflorum) pollen of the Poaceae family cultivated in Southern Brazil has been considered a major sensitizing agent in patie...
HISTORICAL TIPS The science of “Immunology” originated in the 19th century and grass pollens were identified for the first time as the likely trigger of seasonal hay fever in the 1870s. Skin allergy testing became an accepted assessment technique around 1910. Immunoglobulin E (IgE) was identified in the 1960s. The first scholarly report of immunotherapy for allergy appeared by Noon and Freeman ...
A novel intranasal formulation of azelastine HCl (AZE, an antihistamine) and fluticasone propionate (FP, a corticosteroid) in a single spray (MP-AzeFlu [Dymista®]) was studied in four randomized, double-blind, placebo-controlled trials of patients with seasonal allergic rhinitis conducted in the US. Study sites were distributed so that all major US geographic regions and the prevalent pollens w...
Allergy is associated with non-specific symptoms such as fatigue, sleep problems and impaired cognition. One explanation could be that the allergic inflammatory state includes activation of immune cells in the brain, but this hypothesis has not been tested in humans. The aim of the present study was therefore to investigate seasonal changes in the glial cell marker translocator protein (TSPO), ...
IgE-mediated allergy affects >25% of the population in industrialized countries. Repeated contact with the disease-eliciting allergens induces rises of allergen-specific IgE Abs and progression of the disease to more severe manifestations. Our study uses a type of vaccine that is based on genetically modified allergen derivatives to treat allergic patients. We developed hypoallergenic derivativ...
Certain plants produce prodigious amounts of pollen. A single plant can produce 1 million to several million pollen grains in a day. In general, brightly colored flowering plants are of little clinical importance in inhalant allergy because their pollen is designed to be carried by insects (entomophilous) rather than by the wind (anemophilous). Many grasses, trees and weeds produce sufficient q...
For the full versions of these articles see bmj.com Egg allergy affects about 2.6% of preschool children by 3 years of age, and influenza immunisation using egg based vaccines has been classified as a " relative contra indication " (prescribe with extra caution) in this patient group. 1 Until now the numbers of children with egg allergy requiring immunisation has been low, but this may change w...
