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...

To measure the prevalence of allergic rhinitis among European adults and the proportion of undiagnosed subjects, a two-step, cross-sectional, population-based survey in Belgium, France, Germany, Italy, Spain, and the UK was undertaken. Step one of the study involved screening for allergic rhinitis by telephone interview, based on history of symptoms and/or self-awareness of the condition. Step ...

BACKGROUND Allergic rhinitis is a disease impairing quality of life, sleep, and work. A new classification for allergic rhinitis, Allergic Rhinitis and its Impact on Asthma (ARIA), has recently been proposed. OBJECTIVE To study the effect of allergic rhinitis using ARIA definitions to determine severity and duration. METHODS A total of 3052 patients consulting general practitioners for alle...

Background: Oxidative stress may play a role in the pathophysiology of several diseases including allergic rhinitis. Objectives: To evaluate whether plasma total oxidant status (TOS) in the form of plasma reactive oxidants differs between children with allergic rhinitis and healthy controls and to investigate associations between plasma antioxidants and other allergic rhinitis–related immunolog...

Allergic rhinitis, the most common type of rhinitis, generally can be differentiated from the numerous types of nonallergic rhinitis through a thorough history and physical examination. Allergic rhinitis may be seasonal, perennial, or occupational. The most common cause of nonallergic rhinitis is acute viral infection. Other types of nonallergic rhinitis include vasomotor, hormonal, drug-induce...

OBJECTIVE To study the point prevalence of allergic rhinitis and sinusitis in childhood asthma and to examine the relationship among them. METHODS In 250 children (age <13 y) with mild-to-moderte asthma, allergic rhinitis was diagnosed by clinical plus nasal eosinophilia criteria, and sinusitis was diagnosed clinically plus confirmation by computerized tomography scan. RESULTS The point pre...

Introduction: Chronic rhinosinusitis (CRS) is a multifactorial disease. Allergies are considered a predisposing factor to CRS; however, this remains controversial. The objective of this research was to investigate the prevalence of co-morbidities and allergic reaction, and to specify the most common allergens in patients with confirmed CRS.   Materials and Methods: One hundred patients with sig...

UNLABELLED Allergy and asthma can reduce HRQOL as a result of profound physical and psychosocial complications. Most patients with asthma also suffer from rhinitis, which also impairs quality of life. However, the impact of allergic rhinitis on asthmatic patients has not been investigated. OBJECTIVE To assess Quality of life (QOL) in asthmatic patients and assess relative burden of allergic r...

allergic rhinitis is an extremely common disease worldwide. aeroallergens are very often involved in allergic rhinitis and their prevalence may vary in differ¬ent regions. the causative allergens of allergic rhinitis in our area are unknown. the purpose of this study was to determine the prevalence of skin reactivity to different aeroallergens in patients with allergic rhinitis in the city of s...

OBJECTIVES The aims of the study were to establish the prevalence of self-reported allergic rhinitis in an adult Nigerian population and to examine the relationship between asthma and allergic rhinitis. METHODS We conducted an epidemiological study of adults aged between 18 and 45 years in Ilorin, Nigeria from 2005 to 2006. An adaptation of the European Community Respiratory Health Survey que...
