BACKGROUND There is conflicting evidence that traffic-related air pollution is a risk factor for allergic conditions. Few studies have investigated this in adults. In adults, a high proportion of asthma, rhinitis and eczema is triggered by non-allergic factors. We investigated traffic as a risk factor for allergic versus non-allergic asthma and rhinitis, and eczema, in adults. A questionnaire f...

Background The allergic march describes a proposed natural course of allergic disease during childhood. However, different patterns of allergic morbidity have been suggested. The aim of this study was to describe the prevalence of doctordiagnosed asthma and allergic manifestations from infancy into school age and the relationship between early manifestations and the prevalence of asthma at scho...

BACKGROUND IL-12B is a strong candidate gene for asthma. OBJECTIVES We investigated the relationship between IL-12B and asthma, allergic rhinitis, familial asthma, and levels of eosinophils and total immunoglobulin (Ig) E in the serum of asthma patients. METHODS The study group consisted of 53 asthma patients and 60 control patients. Serum total IgE levels, eosinophil count, and the presenc...

Fermentation by Rhizopus spp. has been used as a traditional medicine for treating various inflammatory diseases. Allergic asthma is chronic respiratory disease that caused an exaggerated immune response. This study was conducted to ascertain the anti-inflammatory effects of fermentation extract (RU) on mouse model ovalbumin (OVA)-induced asthma. The animals were intraperitoneally injected OVA ...

BACKGROUND Allergic diseases are very common, with the estimated cumulative prevalence in Colombia for asthma and allergic rhinitis being 22.7% and 31.3% respectively, and with a clear upward trend. A major social as well as economic impact associated with allergic disease has been described. Because in Colombia there are no studies that assess the Health-Related Quality of Life (HRQOL) in alle...

BACKGROUND Dyspnea may be a presenting symptom of type I food hypersensitivity; bronchial hyperactivity, without known asthma, can coexist in patients with food allergy. OBJECTIVE To evaluate airway involvement in young adult patients with food allergy and no asthma and compare the findings to those of patients with food allergy and asthma, with food allergy and allergic rhinitis, with asthma...

The aim of this study was to assess whether the association with social class differed between allergic rhinitis and asthma and whether these associations have changed over time. The Swedish Military Service Conscription Register was linked to two other national registers for 1,247,038 male conscripts in successive cohorts born between 1952 and 1977. The percentage of asthma cases associated wi...

OBJECTIVES Allergic disease may be increased by climate change. Recent reports have shown that typhoon and heavy rain increase allergic disease locally by concentration of airborne allergens of pollen, ozone, and fungus, which are causes of allergic disease. The objective of this study was to determine whether typhoon and heavy rain increase allergic disease in Korea. METHODS This study inclu...

Allergic rhinitis causes major illness and disability worldwide, but it is still underdiagnosed and undertreated. Allergic rhinitis is a risk factor for both the development and for exacerbations of asthma. Up to 30% of patients with rhinitis suffer from asthma, and the majority of patients with asthma suffer from rhinitis. Measurements of allergic status can help to identify risk factors that ...

BACKGROUND Population-based estimates of asthma and allergic rhinitis in sub-Saharan African adults are lacking. We assessed the prevalence and determinants of asthma and allergic rhinitis in urban adult Cameroonians. METHODS A community-based survey was conducted from December 2013 to April 2014 among adults aged 19 years and above (N = 2,304, 57.3% women), selected through multilevel strati...
