Is the increase in asthma prevalence linked to increase in allergen load?

Continued increase in the prevalence of asthma and atopy.

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 stu...

Serum levels of IL-17A increase in Asthma but not in accordance with Serum level of IgE and Asthma Severity

Background and Aims: Recent evidence suggests that T helper (Th) 17 cells are involved in the emergence of asthma. Th17 cells have a key role in inducing inflammation in asthmatic airways thus Interleukin (IL)-17A, the main cytokine of Th17, contributes to airways inflammation. Materials and Methods: We evaluated the level of IL-17A and total immunoglobulin E (IgE) in sera of 100 asthmatic p...

Effect of bradykinin on allergen induced increase in exhaled nitric oxide in asthma.

BACKGROUND Exposure of patients with atopic asthma to allergens produces a long term increase in exhaled nitric oxide (FENO), probably reflecting inducible NO synthase (NOS) expression. In contrast, bradykinin (BK) rapidly reduces FENO. It is unknown whether BK suppresses increased FENO production after allergen exposure in asthma, and whether it modulates FENO via NOS inhibition. METHODS Lev...
