Chronic non-allergic rhinitis

Chronic non-allergic rhinitis is a persistent disorder of the upper respiratory tract characterized by ongoing nasal mucosal inflammation or dysfunction in the absence of systemic IgE-mediated allergic sensitization or active infection It primarily affects adults and is clinically defined by chronic nasal congestion, anterior rhinorrhea, and postnasal drip, typically without the pronounced ocular or nasal pruritus seen in allergic forms The condition encompasses heterogeneous pathophysiologic ph...

The condition encompasses heterogeneous pathophysiologic phenotypes, most commonly non-allergic rhinopathy (vasomotor rhinitis), driven by autonomic dysregulation, neurogenic hyperreactivity, and abnormal vascular tone triggered by nonspecific environmental irritants, temperature shifts, or hormonal fluctuations
