    Study Notes

    Prevalence and Impact of Rhinitis

    • Rhinitis prevalence ranges from 1.8% to 24.2% in children aged 6-7 years and 1.0% to 45% in those aged 13-14 years, with significant increases observed in various centers.
    • Chronic rhinitis affects physical and emotional functioning, leading to absenteeism from school, reduced productivity, and impaired performance.
    • Increased rates of allergic rhinitis incidence were noted in studies, suggesting a correlation with higher living standards in Westernized countries.

    Types of Rhinitis

    • Occupational rhinitis arises from workplace exposures, while work-exacerbated rhinitis occurs in individuals with pre-existing conditions worsened by workplace factors.
    • Common high-risk occupations include laboratory workers, furriers, and bakers.

    Chronic Rhinosinusitis (CRS)

    • CRS is an inflammatory disease characterized by symptoms lasting longer than 12 weeks, with cardinal symptoms including mucopurulent drainage, nasal obstruction, facial discomfort, and decreased sense of smell.
    • Diagnosis requires clinical evaluation and imaging or endoscopic evidence of sinus mucosal inflammation.

    Atrophic Rhinitis

    • Atrophic rhinitis occurs due to nasal crusting, purulent discharge, nasal obstruction, and halitosis.
    • Clinical diagnosis relies on observed symptoms and characteristic findings during examination.

    Idiopathic Rhinitis

    • Changes in estrogen or progesterone may influence idiopathic rhinitis, but supporting evidence is limited.
    • Symptoms may fluctuate in pregnant women, similar to asthma, indicating shared mechanical factors impacting both conditions.

    Systemic Effects of Allergens

    • Allergen exposure can result in systemic inflammation, enhancing nasal responsiveness to histamine and increasing eosinophil levels.
    • Pretreatment with nasal corticosteroids can mitigate allergen-induced hyperresponsiveness.

    Nasal Hyperresponsiveness Mechanisms

    • Nasal hyperresponsiveness is a complex phenomenon involving different pathways and mechanisms, influenced by allergens, histamines, and other triggers.
    • It is vital to distinguish between responses to various stimuli when evaluating hyperresponsiveness, as they may reflect different underlying processes.

    Research and Evaluation

    • Prospective studies provide better insight into the pathophysiology of allergic rhinitis by evaluating participants across different seasons and exposures.
    • Enhanced sensitivity in identifying mechanisms of rhinitis is being achieved through advanced transcriptional analysis of immune cell genes following allergen challenges.
