In Vivo Anti-Inflammatory Effect of H1 Antihistamines in Allergic Rhinitis: A Randomized Clinical Trial




Abstract
Background:
Allergic rhinitis is characterized by a chronic inflammation of nasal mucosa and represents a risk factor for asthma occurrence. H1 antihistamines reduce the symptoms of rhinitis, but some compounds may have anti-inflammatory properties.
Aims:
We evaluated the plasma level of some cytokines in patients with persistent allergic rhinitis (PAR) and their evolution after a 4-week treatment with H1 anti-histamines, as well as the risk of asthma after 1.5 years.

Intakes of apple juice, fruit drinks and soda are associated with prevalent asthma in US children aged 2–9 years



Luanne Robalo DeChristophera1 c1 p1, Jaime Uribarria2 and Katherine L Tuckera3
Abstract
Objective High soft drink consumption has been linked with asthma. Anecdotal evidence links high-fructose corn syrup with asthma. The receptor of advanced glycation end products (RAGE) has emerged as a mediator of asthma. The objectives of the present study were to: (i) assess the correlation between intake of beverages containing excess free fructose (EFF beverages) and asthma in children; and (ii) epidemiologically test the mechanistic hypothesis that intake of high EFF beverages, such as apple juice or beverages sweetened with high-fructose corn syrup, is associated with increased risk of asthma. This hypothesis is based on the possible effect of increases in thein situ intestinal formation of advanced glycation end products (enFruAGE) with EFF, which may be absorbed and play a role in RAGE-mediated asthma.

Purpose: Acute, severe asthma exacerbations can be difficult to predict and thus prevent. Patients who have frequent exacerbations are of particular concern. Practical exacerbation predictors are needed for these patients in the primary-care setting.

Three-month validation of a turbuhaler electronic monitoring device: implications for asthma clinical trial use

Abstract
Background Electronic monitoring of inhaled asthma therapy is suggested as the ‘gold standard’ for measuring patterns of medication use in clinical trials. The SmartTurbo (Adherium (NZ) Ltd, Auckland, New Zealand) is an electronic monitor for use with a turbuhaler device (AstraZeneca, UK). The aim of this study was to determine the accuracy of the SmartTurbo in recording Symbicort actuations over a 12-week period of use.

Management of the polyallergic patient with allergy immunotherapy: a practice-based approach

Review

Open Access

Pascal Demoly12*Giovanni Passalacqua3Oliver Pfaar45Joaquin Sastre6 and Ulrich Wahn7

Abstract
The great majority (60–80 %) of patients consulting specialist physicians for allergic respiratory disease are polysensitized and thus may be potentially clinically polyallergic. However, management approaches to allergen immunotherapy (AIT) in polysensitized and polyallergic patients are not standardized.
An international group of clinicians with in-depth expertise in AIT product development, clinical trials and clinical practice met to generate up-to-date, unambiguous, pragmatic guidance on AIT in polysensitized and polyallergic patients. The guidance was developed after reviewing (1) the current stance of regulatory bodies and learned societies, (2) the literature data on single- and multi-AIT and (3) the members’ confirmed clinical experience with polysensitized patients.

The Allergen Challenge Chamber (ACC) is definitely a serious challenge on the one hand and an innovative solution in allergic rhinitis diagnosis on the other.

Effects of oral vitamin E on treatment of atopic dermatitis: A randomized controlled trial


Fariba Jaffary, Gita Faghihi, Arghavan Mokhtarian, Sayed Mohsen Hosseini

ABSTRACT


Background: The pathogenesis of atopic dermatitis (AD) remains to be determined; recently a possible change in the immune system with production of immunoglobulins is proposed. As vitamin E is a potent antioxidant, with the ability to decrease the serum levels of immunoglobulin E (IgE) in atopic patients, we aimed to evaluate the effect of oral vitamin E on treatment of AD.
