One type of non-allergic non-infectious rhinitis is represented by a heterogeneous group of rhinitis medicamentosa, which can be divided into several pathogenetic types. The most common rebound nasal congestion associated with the use of topical decongestants. Excessive use of intranasal decongestants leads to a decrease in the number of alpha-adrenoreceptors on the surface of cell membranes and uncoupling their connection with the G-protein and the development of tachyphylaxis.

Background: Rhinitis medicamentosa is a non-allergic form of rhinitis that is typically caused by prolonged use of topical nasal decongestants. This condition commonly affects young adults and treatment is not trivial. We aimed to survey Canadian Otolaryngologists to determine practice patterns and their opinions regarding this under-studied condition. Read More

Background: Non-allergic rhinitis is defined as dysfunction and non-infectious inflammation of the nasal mucosa that is caused by provoking agents other than allergens or microbes. It is common, with an estimated prevalence of around 10% to 20%. Patients experience symptoms of nasal obstruction, anterior rhinorrhoea/post-nasal drip and sneezing. Read More

Objective: The objective of this study was to determine whether patients with rhinitis medicamentosa (RM) have an increased odds of having an opioid use disorder (OUD) and which characteristics may predict this association.

Methods: The authors conducted a retrospective case control study of patients 18 years and older who presented to the otolaryngology clinic at an academic medical center from January 2013 through December 2017. Cases, defined as patients who presented with excessive decongestant nasal spray usage based on history, were matched to control patients who presented with chronic rhinitis and did not report regular nasal decongestant usage.

This study was designed to prospectively evaluate the role of nebulized hyaluronic acid (HA) administered for 10 days as treatment for patients with rhinitis medicamentosa (RM). RM is a pathological condition of the nasal mucosa induced by prolonged, excessive or improper use of topical decongestants. It is characterized by persistent nasal congestion that can lead the patient to increase the frequency of application and the quantity of the substance being applied, resulting in dependence on topical nasal decongestants.

Rhinitis medicamentosa (RM) refers to nonallergic inflammation in the nasal mucosa which is caused by the abuse of nasal decongestant and it often occurs in patients with allergic/nonallergic rhinitis along with nasal congestion. RM is characterized by nasal congestion based on long-term use of nasal decongestant, without rhinorrhoea or sneezing. The signs of RM include nasal swelling, thickening, loss of elasticity, and loss of sensitivity to the decongestant. Read More

Objective: To better understand the causes of the exacerbation of rhinitis medicamentosa (RM) induced by oxymetazoline (OMZ) or benzalkonium chloride (BKC), we examined the impact of pretreatment with OMZ or BKC on cultured human nasal epithelial cells. We also examined the effect of mometasone furoate (MF) on the cultured human nasal epithelial cells treated with OMZ or BKC.

Methods: Cells of the human nasal epithelial cell line HNEpC were treated with OMZ or BKC, and the OMZ- and BKC-induced expression of histamine H1 receptor (H1R) mRNA was assayed using real-time polymerase chain reaction. Read More

Rhinitis is characterized by one or more of the following nasal symptoms: congestion, rhinorrhea (anterior and posterior), sneezing, and itching. It is classified as allergic or nonallergic, the latter being a diverse syndrome that is characterized by symptoms of rhinitis that are not the result of IgE-mediated events. Excluding infectious rhinitis and underlying systemic diseases, clinical entities that can be classified among the disorders that make up the nonallergic rhinitis syndromes include gustatory rhinitis, nonallergic rhinitis with eosinophilia syndrome (NARES), atrophic, drug-induced (rhinitis medicamentosa), hormone induced, senile rhinitis (of the elderly), rhinitis associated with chronic rhinosinusitis with or without nasal polyps, and the idiopathic variant formerly known as vasomotor rhinitis but more accurately denoted as nonallergic rhinopathy (NAR).

Introduction: Systemic and topical nasal decongestants are widely used in otorhinolaryngology and general practice for the management of acute rhinosinusitis and as an adjuvant in certain forms of chronic rhinosinusitis. These products, very effective to rapidly improve nasal congestion, are sometimes available over the counter and can be the subject of misuse, which is difficult to control. The Société Française d'ORL has recently issued guidelines concerning the use of these decongestants in the doctor's office and the operating room. Read More

The diagnosis and treatment of rhinitis, sinusitis, and epistaxis during pregnancy present unique challenges to the otolaryngologist. Poorly controlled sinonasal disease may have significant adverse effects on the mother's quality of life and pregnancy outcomes and the lack of adequately controlled safety data limits the clinician's ability to make informed decisions about management. At the conclusion of this discussion, the reader should be familiar with the available literature and evidence-based guidelines regarding the safety and indications for radiographic imaging, clinical testing, medical intervention, and surgical treatment of sinonasal disease in pregnant patients.

Nonallergic rhinitis represents a non-IgE-mediated group of disorders that share the symptoms of nasal congestion, rhinorrhea, sneezing, and/or postnasal discharge but not pruritus that characterizes allergic rhinitis. Nonallergic rhinitis may be divided into two broad categories, inflammatory and noninflammatory etiologies. The inflammatory causes include postinfectious (viral and bacterial), rhinitis associated with nasal polyps, and nonallergic rhinitis with eosinophilia, where eosinophils are present in nasal smears but skin testing for aeroallergens is negative.

It is important to consider a comprehensive differential of possible rhinitis types when considering the diagnosis of chronic rhinitis, including at least 9 subtypes of nonallergic rhinitis: drug-induced rhinitis, gustatory rhinitis, hormonal-induced rhinitis, infectious rhinitis, nonallergic rhinitis with eosinophilia syndrome, occupational rhinitis, senile rhinitis, atrophic rhinitis, and nonallergic rhinopathy. This article focuses on some of the most common types of chronic rhinitis, including mixed rhinitis (allergic and nonallergic overlap), rhinitis medicamentosa, hormonal rhinitis, rhinitis of the elderly, and gustatory rhinitis.

Background: In clinical trials, only about 60% of subjects report an excellent response to intranasal steroids, suggesting a need to add therapies to intranasal steroids to provide additional efficacy.

Rhinitis medicamentosa occurs with repeated and prolonged use of topical decongestants. The resultant reduced ability to respond to decongestants mediated via enlarged capillary endothelial gaps can lead to profuse bleeding during turbinate surgery. We recommend that patients with rhinitis medicamentosa be weaned off topical decongestants prior to elective turbinate surgery to minimize this complication. Read More

Rhinitis of allergic and viral origin is often self-treated by patients with locally applied vasoconstrictor decongestant drugs. In turn, prolonged use of these agents produce an inflammatory condition termed rhinitis medicamentosa. Cationic drugs are sequestered into cells via various mechanisms, including mitochondrial concentration and V-ATPase-driven trapping in vacuoles that swell by an osmotic mechanism. Read More
