BACKGROUND The existence of a local allergic rhintis was proposed on the basis of the detection of nasal IgE in the absence of a systemic sensitization. Nevertheless, the significance of this phenomenon remains still unclear. We assessed the presence of mucosal nasal IgE in patients with ascertained allergic rhinitis, nonallergic rhinitis with inflammation and in healthy controls. METHODS Con...
Background : Allergic rhinitis is among the most common respiratory disorders that has been increased during the recent decades due to air pollution. Most of prior studies have investigated the association between allergic rhinitis and hearing loss among children, however, scanty reports address the issue among adults, thus the present study was conducted among patients referring to a universit...
allergic fungal sinusitis (afs) has been recognized as an important cause of chronic sinusitis commonly caused by aspergillus spp. and various dematiaceous fungi like bipolaris, alternaria, curvalaria, and etc. ulocladium botrytis is a non pathogenic environmental dematiaceous fungi, which has been recently described as a human pathogen. ulocladium has never been associated with allergic fungal...
BACKGROUND Indoleamine 2,3-dioxygenase (IDO) is a tryptophan catalyzing enzyme. It has been suggested that it has a role in lower airway allergic inflammations, but its role in allergic rhinitis has not been investigated. OBJECTIVE Our aim was to evaluate the expression of IDO in the nasal mucosa of allergic rhinitis patients allergic to birch pollen during peak exposure to birch pollen aller...
BACKGROUND Increased fractional exhaled NO concentrations (FENO) and blood/tissue eosinophilia are frequently reported in allergic children with mild asthma and are thought to reflect the intensity of the inflammation characterising the disease. The aim of this study was to investigate possible differences in FENO levels or in the intensity of the blood eosinophilia in allergic and non-allergic...
INTRODUCTION Allergic women have been reported to give birth to more children than non-allergic women, speculatively explained by the former's predisposition for Th2 polarization, possibly favoring pregnancy. AIM The aim of this study was to test the hypothesis that allergy is associated with more Th2-deviated responses to paternal antigens throughout pregnancy. METHODS Blood samples were c...
To differentiate non-allergic chronic rhinosinusitis (vasomotor rhinitis) from allergic rhinitis, a characteristic protein in the nasal discharge was studied. The subjects consisted of 10 patients with perennial allergic rhinitis to house dust, 10 patients without perennial rhinitis without antigen (clinically defined as non-allergic chronic rhinosinusitis) and 5 normal volunteers without nasal...
