1. objectives. To compare the efficacy and the safety of mometasone furoate nasal spray (MFNS; Nasonex 200μg, daily) alone versus a combination with montelukast (singulair 10mg, daily) in chronic rhinosinusitis (CRS) with asthma after functional endoscopic sinus surgery (FESS) for improvement the clinical control of CRS 2. the clinical hypotheses. The investigators hypothesize that postoperative combined montelukast and MFNS can better improve clinical control of CRS concomitant with asthma after FESS compared with MFNS alone. 3. study design This study is a 9-month randomized, open-label, controlled interventional study.
The purpose of this trial is to test the hypothesis that a treatment diet low in omega-6 fatty acids and high in omega-3 fatty acids can cause improvement in asthma symptoms, nasal symptoms, and pulmonary function in patients with aspirin-exacerbated respiratory disease (AERD).
This randomized, double-blind, placebo-controlled clinical trial enrolled subjects with eosinophilic CRSwNP. Subjects were randomized to receive either budesonide inhalation suspension or placebo for 14 days. Visual analogue scales (VAS）of nasal symptoms, endoscopic polyp scores and morning serum cortical levels were assessed pre- and post-treatment. Polyp samples were evaluated for inflammatory cytokines, matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs) by immunoassay; collagen by histochemistry; and frequencies of different inflammatory T cell infiltration by flow cytometry. this study is undertaken to evaluate the efficacy of short-term prescription of budesonide inhalation suspension via transnasal nebulization by clinical and immunologic assessments. As outcome parameters for remodeling, differences in the expression of collagen and albumin were investigated before and after budesonide treatment. Meanwhile, TGF-β, MMPs and TIMPs expression differences in nasal polyps were investigated to explore underlying mechanisms of tissue reconstitution.
Primary Objective: To evaluate the efficacy of dupilumab (SAR231893 / REGN668) in the treatment of bilateral Nasal Polyposis (NP) by assessment of the endoscopic nasal polyp score in comparison to placebo. Secondary Objectives: To evaluate effect of dupilumab with regards to: - symptoms of sinusitis - sinus Computed Tomography (CT) scan - nasal polyp score in the sub-group of patients with co-morbid asthma - Safety and tolerability
This prospective study aimed to evaluate the usefulness of squamous cell carcinoma antigen (SCCA) as a clinical marker of sinonasal inverted papilloma (IP). The potential benefit of SCCA in the diagnosis of unilateral nasal pathology and as a marker of hidden recurrence was evaluated as well. Blood samples from patients with sinonasal IP were examined to determine serum SCCA levels before surgery, the day after surgery, and every 6 months during follow-up. Preoperative and postoperative levels of SCCA were compared.
The aim of the project is to define the frequency with which EER is present in patient with chronic rhinosinusitis (CHR). The measurement will be carried out with a 24-hour monitoring of the pH using the Restech system. This modern device is equipped with a narrow antimony probe. The sensor is able to record not only liquid but also aerosol reflux episodes. The second aim is to determine the relation among EER, CHR and asthma bronchiale. We will compare the presence of reflux in three different patient groups (1. CHR without nasal polyposis, without asthma bronchiale or ASA syndrome, 2. CHR with nasal polyposis, without asthma bronchiale or ASA syndrome, 3. CHR with nasal polyposis and asthma bronchiale and/or ASA syndrome). We expect to find a significantly more frequent presence of EER in patients with CHR and asthma bronchiale or ASA syndrome. In case our hypothesis is confirmed, it will be especially these patients(with a difficult to manage nasal polyposis) benefiting from the antireflux therapy.
Topical nasal steroid sprays are the mainstream treatment for patients with nasal polyps. Polyps tend to recur after surgery and topical nasal steroid sprays are used as the primary medical management to prevent continued growth. More recently high dose topical nasal steroid sprays are used. It is thought that the higher dose will penetrate the sinus cavities at an increased dose and will allow for greater control of polyp growth. Safety studies have been performed which have shown no suppression of the pituitary axis with long term high dose topical steroid or changes in intraocular pressure. However, studies in efficacy are limited despite their widespread use. The objective of this study will be to compare the effectiveness of two topical nasal steroid sprays in patients with recurrent nasal polyps.
The RESOLVE Study is a randomized controlled trial with the S8 Sinus Implant in 100 chronic sinusitis patients with recurrent nasal polyps.
We hypothesize that the miRNA expression in subjects with nasal polyps and Aspirin-exacerbated respiratory disease (AERD) differs from the miRNA expressed in subjects with nasal polyps but without Aspirin-exacerbated respiratory disease (AERD).
