Background Atopy varies in people of different ages owing to physical conditions and exposure allergens. We aimed cluster based on atopic severity using K-means analysis identify incidence, severity, as well the association among peripheral eosinophils, IgE sensitisation. Methods Consecutive patients (n = 7654) with allergic symptoms undergoing allergen-specific tests were included from 2013 20...

Families with 189 children confirmed as FA (according to self report and doctor’s diagnosis) and other 213 randomly selected health children completed a standardized questionnaire related to respiratory and food allergic symptoms, family hist...

OBJECTIVE We examined asthma risk factors among 274 Puerto Rican children born in New York to atopic mothers. METHODS We prospectively followed the cohort to measure aeroallergens in their homes and assess allergic sensitization. Baseline data are presented. RESULTS Maternal smoking was significantly higher among women born on the continental United States (25%) vs. those born elsewhere (11...

Nowadays, there is a wide range of different methods available for the monitoring pollen and allergens, but their relative efficiency sometimes unclear, as conventional does not thoroughly describe allergenicity. This study aims to evaluate airborne pollen, allergen, protein levels, associating them with meteorological chemical parameters. The sampling was performed in Bologna (Italy) during gr...

BACKGROUND Skin prick test (SPT) and fluorescence enzyme immunoassay (FEIA) are widely used for the diagnosis of Immunoglobulin-E (IgE)-mediated allergic disease. Basophil activation test (BAT) could obviate disadvantages of SPT and FEIA. However, it is not known whether BAT gives similar results as SPT or FEIA for aeroallergens. OBJECTIVES In this study, we compared the results of SPT, BAT a...

OBJECTIVE To investigate the prevalence and trends of sensitisation to common aeroallergens among outpatients with allergic rhinitis (AR) in Guangzhou, China, over the past decade. DESIGN A retrospective study; linear-by-linear association and simple linear regression were used to determine the trends in the prevalence of aeroallergen sensitisation. SETTING One grade-A hospital in Guangzhou...
