Filter by:The purpose of this study is to compare the effectiveness of intranasal Triamcinolone delivered through a bio-absorbable nasal dressing verses oral steroids and a saline soaked dressing, in the treatment and prevention of early nasal polyposis.
This is a randomized, double blind, placebo controlled, parallel group, study in patients with chronic rhinosinusitis with or without nasal polyps. The objective is to test the clinical efficacy of long-term low dose oral doxycycline on wound healing quality after endoscopic sinus surgery.
The purpose of this study is to determine if Vitamin D supplementation improves clinical and immunologic parameters in chronic rhinosinusitis with nasal polyps.
The investigators are doing this research study to learn more about a drug called Xolair (omalizumab). The investigators want to see if it is an effective treatment for chronic rhinosinusitis (CRS). Specifically, the investigators want to see whether Xolair will make nasal polyps smaller and less thick, and relieve symptoms in people with CRS. Polyps are abnormal growths of tissue that can grow in the lining of your sinuses (the inside of your nose). The investigators also want to find out if it is safe to use (whether it causes side effects).
Fluticasone furoate is being studied to determine whether treatment with a topical nasal steroid, in patients with existing nasal polyps , can not only improve symptoms but also suppress the recurrence of clinically significant nasal polyp obstruction and prevent surgical intervention.
Analysis of differential gene expression in patients with chronic rhinosinusitis without polyps compared to unaffected patients. Correlation of abnormal gene expression with surgical outcomes.
This is a study to evaluate the cause of chronic sinus disease. Oral steroids have long been used in the treatment of inflammatory conditions including chronic sinusitis, asthma, and arthritis. However, it is not well known exactly which patients will benefit from steroids when used in the treatment of chronic sinusitis. For some doctors, it is common practice to use these medications prior to planned sinus surgery, to lessen the inflammation and possibly help the healing process. Other doctors feel oral steroids may not be helpful in this way, and there is no conclusive data as to whether this practice has a long term benefit.
Background: Nasal polyps are found in about 5% of asthmatic patients.A close link exists between the upper and lower airways and the concept of the "United Airways" has emerged mainly from studies on allergic rhinitis and asthma. However, other upper airway diseases, such as chronic sinusitis and nasal polyposis may influence lower airway diseases. As for nasal polyposis, eosinophils are the major effector cells in asthma and have been associated with a worsening of this condition. Aim: To compare normal nasal mucosa and nasal polyp biopsies from subjects with nasal polyposis with or without asthma. Hypothesis: Nasal polyps from asthmatic subjects show a more aggressive pro-inflammatory pattern of cytokine expression compared to nasal polyps from non asthmatic subjects, and therefore contribute to the development and severity of asthma.
This is the first randomized parallel group clinical trial looking at oral prednisolone induced medical nasal polypectomy followed by maintenance on topical steroid therapy in patients with nasal polyposis. This study also looks at the effect of aspirin sensitivity and the factors linking nasal polyps with asthma. We have also taken baseline measurements of a variety of blood, surface and biopsy markers to assess for potential to predict steroid response. Finally, the still unchartered link between nasal polyps and asthma will be explored by measuring Staphylococcal superantigens in serum before and after treatment.
The purpose of this study is to determine if intranasal Beclomethasone delivered by aerosol or spray is more effective in treatment of nasal polyps.
