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.
