BACKGROUND Atopic dermatitis is an inflammatory skin disease that can be triggered by many factors. Several reports confirm the role of airborne allergic agents as aggravating or triggering factors. The patch test with airborne allergic agents or the atopy patch test was suggested to evaluate the role of these allergens in atopic dermatitis. OBJECTIVE This study aimed at evaluating the positi...

BACKGROUND/AIM Previous literature on the association between obesity and atopy has been inconsistent. The aim of the study was to determine the relationship between obesity and atopic sensitization in adults. METHODS The study included a total of 1,997 residents aged 18-79 years and was conducted in the town of Humboldt, Sask., Canada in 2003. Body mass index (BMI) and waist circumference (W...

IgE, and atopy. Results: We measured the total serum IgE of 155 children. The number of obese and normal weight children with family history of atopic disease who had high level of total serum IgE were 30 and 25 respectively, whereas these children who had normal level of total serum IgE were 6 and 15 respectively [OR 1⁄4 1.9 (95% CI 0.9-3.9)]. On the other hand, obese and normal weight childre...

OBJECTIVE To determine the prevalence of atopy and to evaluate clinical, laboratory, and radiological profiles in patients with COPD. METHODS This was a cross-sectional study involving outpatients with stable COPD (defined by the clinical history and a post-bronchodilator FEV1/FVC < 70% of the predicted value). The patients completed a questionnaire regarding clinical characteristics and atop...

Aims: To describe the change in the prevalence of wheeze, diagnosed asthma, and atopy in Wagga Wagga, NSW, Australia, between 1992 and 1997, and to compare this to the increase in prevalence reported between 1982 and 1992. Methods: A cross sectional study of the prevalence of respiratory symptoms and atopy in schoolchildren aged 8–11 years (n=1016, response rate 71%) in 1997 compared with studi...

PURPOSE To estimate the prevalence of atopy (ie, allergen sensitization) in a sample of adult asthma outpatients. METHODS Population consisted of a total of 218 patients, 18 to 55 years of age, who were currently receiving care for asthma; and 13 physicians, whose specialties were Family Practice, Allergy, or Pulmonology and who were providing care to at least 10 to 15 asthma patients weekly....

BACKGROUND Exhaled nitric oxide (FE(NO)) is raised in asthmatic children, but there are inconsistencies in the relationship between FE(NO) and characteristics of asthma, including atopy, increased airway responsiveness (AR), and airway inflammation. The aim of this study was to investigate the relationship between FE(NO) and asthma, atopy, and increased AR in children. METHODS One hundred and...

Skin tests and exercise tests were performed on children with cystic fibrosis (CF) and first-degree relatives of CF children. Positive skin tests were found in 56% of patients and 19% of relatives, but the prevalence of atopy in CF patients bore no relationship to its prevalence in their relatives. Increased 0ronchial lability, mainly due to bronchoconstriction, was present in 54% of patients a...
