BACKGROUND Various studies have reported a low prevalence of allergic rhinitis in farmers and farmers' children. We sought to investigate whether the protective effect of childhood farm environment is conserved throughout adulthood and how it corresponds to different degrees of urbanization. METHODS A questionnaire on respiratory health was mailed in 2008 to 30,000 randomly selected subjects ...

BACKGROUND Supplementation with long-chain n-3 polyunsaturated fatty acids (LCPUFAs) has been found to reduce the development of allergic disease. OBJECTIVE The aim of this study was to compare the effectiveness of fish oil diets rich in eicosapentaenoic acid (20:5n-3; EPA) or docosahexaenoic acid (22:6n-3; DHA) in suppressing food allergic symptoms. METHODS Mice were fed a control diet (10...

Here, we report on the prevalence of allergic conjunctivitis and positive skin prick test (SPT) results in relation to respiratory allergic conditions among patients with symptoms of allergies at a respiratory outpatient clinic. A questionnaire survey of symptoms (i.e., asthma-like, rhinitis, and conjunctivitis symptoms) involving 1522 patients was carried out. The responses of 1242 patients in...

Laboratory animal workers are at risk of developing allergic symptoms, of which asthmatic symptoms are the most severe. The aim was to study the relationship between allergic symptoms due to working with rats and variability and changes in peak expiratory flow (PEF). Several indices were used on the basis of the amplitude of the PEF or the differences in PEF between days with and without exposu...

Allergic rhinitis affects up to 40% of children but is commonly undiagnosed. Careful assessment of nasal symptoms allows for the most appropriate therapeutic options to be chosen. Allergen avoidance is often difficult in practice. Antihistamines are of limited benefit in allergic rhinitis caused by house dust mite and other perennial allergens, where symptoms, predominantly nasal obstruction, a...

Article type: Review Article Food allergy is estimated about 8% in children. The relationship between food and manifestation of allergy symptoms and its confirmation for accurate diagnosis is very important. Allergic rhinitis is a common disease with a prevalence of 40% among different societies. The prevalence of food-induced allergic rhinitis appears to be less than 1 percent. Food reactions ...

Background A previous study by our group (JACI 2003;112:45-50) showed a significant allergic gastrointestinal inflammation in birch pollen allergic patients with gastrointestinal symptoms during the birch pollen season. The pathophysiological mechanisms of this type of allergic reaction are still poorly studied. However it is not yet explored if all birch pollen patients have signs of gastroint...

Quercetin offers interesting beneficial options in clinical practice by providing anti-allergic and anti-inflammatory activities. This article reports discusses the effectiveness of oral administration quercetin Phytosome™ adults presenting allergic conjunctivitis. The analysis was conducted evaluating both subjective symptoms reported individuals; objective tear film instability due to conjunc...

Atopy is a syndrome characterized by immediate hypersensitivity reactions to common environmental antigens. The "hygiene hypothesis" stipulates that childhood infections are associated with a lower risk of allergies. Not much has been published about the effects that the treatment of pulmonary tuberculosis (TB) has on allergies, specifically allergic rhinitis. We conducted a study to investigat...

Objective A group of 148 peach allergic patients, recruited in a ongoing clinical study (Clinical Trials.gov, protocol ID NCT00715156) aimed at studying the relationship between the clinical manifestations to peach and the positivity to different peach major allergens (Pru p 3, 1 and 4), were divided into 2 groups according to peach induced symptoms: group A (mild-OAS; 76 pts) and group B (seve...
