Does atopy influence the effectiveness of treatment of adenoid hypertrophy with mometasone furoate?

BACKGROUND: The effect of topical mometasone for adenoid hypertrophy treatment is well established. Nevertheless, the influence of atopy on this treatment remains ill defined. OBJECTIVE: This study aims to compare the effects of topical mometasone furoate treatment on the adenoid tissue between atopic and nonatopic children. METHODS: Fifty-one children with obstructive respiratory complaints underwent a semistructured clinical questionnaire on nasal symptoms, prick test, and nasoendoscopy. Nasoendoscopic images were digitalized, and both adenoid and nasopharyngeal areas were measured in pixels; the relative adenoid/nasopharyngeal area was calculated. Patients were initially treated for 40 days with nasal saline solution. In a subsequent 40-day period, topical mometasone furoate (total dose, 100 µg/day) was used. RESULTS: Topical mometasone significantly improved nasal obstruction, snoring, and apnea and also significantly reduced the adenoid tissue area related to the nasopharynx (p < 0.0001). Treatment with this glucocorticoid was not influenced by atopy, neither for symptoms nor for adenoid area. CONCLUSION: Topical mometasone furoate significantly reduced the adenoid tissue area and led to a supplementary improvement of nasal symptoms. This improvement was similar for atopic and nonatopic patients.

Objective reduction in adenoid tissue after mometasone furoate treatment.

OBJECTIVE: Chronic rhinitis and adenoid hypertrophy are the main causes of nasal obstruction in children and proper treatment of these factors seem essential for controlling nasal obstructive symptoms. This study aims to evaluate the effects of topical mometasone treatment on symptoms and size of adenoid tissue in children with complaints of nasal obstruction and to compare this approach to continuous nasal saline douching plus environmental control alone. METHODS: Fifty-one children with nasal obstructive complaints were submitted to a semi-structured clinical questionnaire on nasal symptoms, prick test and nasoendoscopy. Nasoendoscopic images were digitalized, and both adenoid and nasopharyngeal areas were measured in pixels. The relation adenoid/nasopharyngeal area was calculated. Patients were subsequently re-evaluated in two different periods: following 40 days of treatment with nasal douching and environmental prophylaxis alone; and after an subsequent 40 day-period, when topical mometasone furoate (total dose: 100µg/day) was superposed. RESULTS: Nasal symptoms and snoring significantly improved after nasal douching, and an additional gain was observed when mometasone furoate was included to treatment. Saline douching did not influence the adenoid area, whereas a significant reduction on adenoid tonsil was observed after 40 days of mometasone treatment (P<0.0001). CONCLUSION: Nasal saline douching significantly improved nasal symptoms without interfering in adenoid dimension. In contrast, mometasone furoate significantly reduced adenoid tissue, and led to a supplementary improvement of nasal symptoms.
