Active clinical trials for "Sinusitis"

This randomized study compares operative techniques in chronic rhinosinusitis with polyposis (CRSwNP) surgery. It aims to evaluate outcomes in asthma and CRSwNP, safety and costs. The investigators want to see if patients with certain clinical and/or genetic predispositions will benefit from extended surgery. They also aim to find biomarkers for detection and management models for of severe airway inflammation and to further develop markers for progressive disease forms.

The aim of the work is to examine the efficacy of montelukast as an adjunct to steroid therapy in patients with chronic rhinosinusitis with nasal polyps.

Multicenter, phase III, randomized, blinded, controlled, parallel group with safety extension phase with crossover or continued treatment.

Chronic sinusitis is one of the most common chronic diseases in North America, with over 5% of the Canadian population affected by the disease. Until now, treatment with surgery has been performed only in the operating room. Recently a smaller surgical procedure that is done in the clinic for some patients with chronic sinusitis with polyps has been found to result in symptom control that appears to be similar to that which occurs with sinus surgery. Performing the smaller clinical procedure has advantages including a shorter recovery time for the patient, a much lower cost to the health care system for the procedure, and a shorter patient wait time for the procedure to be done in comparison to sinus surgery performed in the operating room. To know with greater certainty that the procedure performed in the clinic is as good as the operating room sinus surgery, a large multiple investigator randomised clinical trial has been designed. However, before carrying out that trial, a practice run or internal pilot study of that trial is required to ensure that the trial can recruit patients at the rate that is anticipated and that the procedures to obtain the measurements being used for the larger study are adequate.

Reducing inappropriate antibiotic use is a key strategy to mitigate antibiotic resistance and adverse health effects associated with antibiotic exposure. The Broad Implementation of Outpatient Stewardship (BIOS) project focuses on broadly implementing an evidence-based intervention to improve antibiotic prescribing for acute respiratory tract infections in pediatric outpatient settings. Primary aims include: (1) examining the acceptability, feasibility and utility of a focused implementation strategy on improving intervention adoption and impact and (2) measuring the effectiveness of the intervention to reduce unnecessary broad-spectrum antibiotic prescription.

This observatory aims to collect, as widely as possible, the Italian cases of patients with uncontrolled CRS. Patient will be enrolled by the centers of the Italian Network of Rhinosinusitis (Rhinosinusitis Italian Network: RINET), and they will be treated using a multidisciplinary team approach (allergists, otolaryngologists and pneumologists) in a real-world clinical set-up. This real-life chronic rhinosinusitis registry aims at longitudinal data collection from patients attending specialist care centres across Italy.

This project focuses on researching chronic rhinosinusitis in patients, employing image processing techniques and molecular biology methods to jointly determine the research objectives: Investigating heterogeneity. Developing an intelligent assessment model. Creating a visual tool for diagnosis and prognosis.

The purpose of this study is to investigate the relationship between long-term use of systemic steroids in patients with upper and lower respiratory tract diseases and their own production of cortisol (cross-sectional), as well as whether those with low cortisol levels have an impact on bone density. As patients with CRSwNP have a high use of steroids, they routinely undergo a DEXA scan at the Respiratory Clinic, Department of Ear-Nose-Throat Surgery and Audiology (ENT) - Rigshospitalet (RH) to examine whether their bone density and structure are affected. The scan will be included as a clinical secondary outcome to assess whether systemic steroid use has an impact on this. The purpose of the study is therefore to compare steroid intake, baseline P-cortisol, the body's response to ACTH (measured by cortisol levels after the test), and bone density in patients with chronic sinusitis (CRS) with and without asthma in an unselected population at the Respiratory Clinic (cross-sectional). In addition, at the 4-month follow-up (exploratory follow-up, pilot project), it will be investigated whether good adherence (>80%) to inhalation therapy (nasal steroid and lung steroid) and additional treatment with biologicals has a negative effect on the body's own production of P-cortisol.

This clinical trial will evaluate the safety, tolerability and effectiveness of GLS-1200 nasal spray in addition to the standard of care after endoscopic sinus surgery in people with chronic sinusitis.

Asthma and chronic rhinosinusitis with nasal polyps (CRSwNP) are frequently described as unified airway inflammatory diseases. Both heavily impacts quality of life with substantial productivity loss. They share the same pathophysiologic pattern based upon proTh2 immune response with blood eosinophils recruitment. Eosinophils are the major actor of persistent mucosal inflammation by promoting their own survival, by attracting other inflammatory cells and by producing cytotoxic proteins involved in mucosal remodeling. Promising anti-Th2 therapeutic approaches (i.e.anti-IgE, anti-interleukin 5 (IL-5), anti-IL-4, anti-IL-13) are considered as effective alternative options to long-term corticosteroid treatment. Their advantage in recalcitrant CRSwNP is under consideration. Moreover, we still need to delineate the good responders to improve theirs indications. The objective is to assess blood eosinophil immunophenotypes in asthma or CRSwNP. Flow cytometric expression of activation markers on eosinophil membrane will be compared with a group of healthy subjects. Innovative data on eosinophil involvement in airway diseases will be obtained. The major outcome will be to depict patients' endotypes for a better selection of immunotherapies.
