[Control of hormonal rhinitis symptoms in patients with hypothyrosis: pathogenetic and clinical aspects]

One of the poorly studied sections of the pathology of ENT organs is chronic rhinitis in patients with hypothyroidism, the pathogenesis of which has not been fully understood, the diagnosis causes significant difficulties, and there are no recommendations for treatment. Despite receiving replacement therapy with levothyroxine, the symptoms of rhinitis persist.

To study the effectiveness of the use of intranasal glucocorticosteroids in patients with chronic rhinitis and hypothyroidism.

Patients with chronic rhinitis and hypothyroidism used mometasone nasal spray 100 mcg 1 time per day for a course of treatment of 2 months (n=60). To assess the symptoms of rhinitis, a visual analog scale (0-10 points), endoscopic examination of ENT organs, anterior active rhinomanometry were used. Evaluation of mucociliary transport was used a saccharin test. The concentration of transforming growth factor (TGF-β1) in nasal secretion and blood serum was studied by ELISA (Enzyme-Linked Immunosorbent Assay), the number of metabolites of NO - nitrites+nitrates (NO_x) was recorded by colorimetric method.

The use of mometasone nasal spray in patients with hypothyroidism helped to reduce complaints on a visual-analog scale (difficulty in nasal breathing, rhinorrhea) and improve nasal breathing according to anterior active rhinomanometry. The concentrations of TGF-β1 and NO_x in nasal secretions before mometasone treatment were higher than after treatment, which probably indicates the contribution of these substances to the formation of edematous hypertrophic changes from the nose in patients with hypothyroidism.
