Background/aim: Allergic rhinitis (AR) is a respiratory disease caused by inflammation of the nasal mucosa. Intranasal corticosteroids (ICs) are an effective treatment for AR; however, their use has been associated with atrophy in nasal mucosae. Because DNA damage has been linked to several chronic diseases, we hypothesize that use of ICs could cause DNA damage in nasal mucosa cells, leading to mucosal atrophy and septal perforation. Materials and methods: Sixty patients with moderate or severe AR were divided randomly into two groups...

Background Mometasone furoate, one of the second generation intranasal corticosteroids, is currently used in suspension form due to its poor solubility. However, this is not favorable for nasal application because of the rapid elimination of the instilled drug from the nasal cavity by mucociliary clearance and delayed onset of action due to the slow dissolution of drug in suspension. Objective The aim of this study was to determine the antiallergic effects of mucoadhesive thermosensitive in situ gel containing mometasone furoate that we developed previously to prolong the contact between the drug and nasal mucosa and to prevent drainage of the formulation in an ovalbumin-induced rat model of allergic rhinitis...

Neurogenic inflammation plays a role in the pathophysiology of allergic rhinitis. Highly effective in reducing the sensory irritation caused by some substances, strontium salts directly affect C-type nerve fibers. The aim of this study was to compare the efficacy of mometasone furoate and strontium chloride on early-phase symptoms in a rat model of allergic rhinitis. Wistar albino rats (n = 24) were randomly divided into three groups: the mometasone group, receiving 1 μg mometasone furoate (2 µl/site); the strontium 3% group, receiving 3% strontium chloride (2 μl/site); and the strontium 5% group, receiving 5% strontium chloride (2 μl/site)...

BACKGROUND: Topical intranasal corticosteroid sprays (INCSs) are standard treatment for nasal polyps (NPs), but their efficacy is reduced by poor patient compliance and impaired access of drug to the sinus mucosa. A corticosteroid-eluting sinus implant was designed to address these limitations in patients with recurrent polyposis after sinus surgery by delivering 1350 μg of mometasone furoate (MF) directly to the ethmoid sinus mucosa over approximately 90 days. METHODS: A randomized, sham-controlled, double-blind trial was undertaken in 300 adults with refractory chronic rhinosinusitis with NPs (CRSwNP), who were candidates for repeat surgery...

PURPOSE: Nasal cytology is important in the diagnosis and treatment of nasal inflammatory diseases. Treatment of allergic rhinitis (AR) according to nasal cytology has not been fully studied. We plan to explore the individualized treatment of AR according to nasal cytology. METHODS: Nasal cytology from 468 AR patients was examined for inflammatory cell quantity (grade 0-5) and the percentage of neutrophils and eosinophils. Results were subdivided into the following categories: AR(Eos), eosinophil ≥50% of the whole inflammatory cells; AR(Neu), neutrophils ≥90%; AR(Eos/Neu), 10%≤ eosinophil <50%; AR(Low), grade 0/1 inflammatory cell quantity...
