NCT07574294
Background: "Remission" is a primary therapeutic goal in severe asthma and chronic rhinosinusitis with nasal polyps (CRSwNP), though definitions vary regarding olfactory function. We evaluated "Dual Remission" kinetics in patients treated with dupilumab over 24 months. Methods: This single-center retrospective study analyzed 28 patients with comorbid severe asthma and CRSwNP. Dual Remission was defined as simultaneous asthma remission (Asthma Control Test (ACT) ≥ 20, no exacerbations, no oral corticosteroids (OCS) and stable lung function) and CRSwNP remission (Sino-Nasal Outcome Test-22 (SNOT-22) \< 40, Nasal Polyp Score (NPS) \> 1). We additionally analyzed "Complete Recovery" by applying a stricter composite definition requiring the restoration of normosmia (Sniffin' Sticks score \> 12). Results: At baseline, patients exhibited uncontrolled disease (median ACT 19, NPS 6). Treatment led to rapid asthma remission (85.7% at 12 months, 100% at 24 months). CRSwNP remission was slower but progressive, rising from 57% at 12 months to 88% at 24 months, demonstrating a significant "catch-up" phenomenon. Consequently, Dual Remission rates increased from 54% to 88% by month 24. When applying the stricter "Complete Recovery" criteria requiring normosmia, only 32% met the goal. Conclusion: Dupilumab is highly effective, enabling 88% of patients to achieve Dual Remission after 24 months. However, full olfactory restitution is distinct from structural polyp regression and harder to achieve, likely due to persistent neuroepithelial damage.
NCT03725956
Nasal polyposis (NP) is a chronic inflammatory disease of the nasal and sinus mucosa leading to protrusion of edematous polyps in the nasal cavity. Prevalence of NP among the chronic rhinosinusitis patients is 25-30 %. NP leads to significant limitations in physical, emotional and social aspects of life of the affected patients. Sleep disorder is frequently reported by those patients with impaired nasal breathing. Till now few studies have objectively assessed the impact of NP on sleep quality. the objectives are to figure out sleep disturbances in NP and to analyze the outcomes of sinus surgery on sleep recovering.
NCT07548866
The study aims to identify the advantages and disadvantages of each of the three methods of airway management during FESS.
NCT06454240
This is a parallel, Phase 2, 2-arm, multicenter, randomized, double-blind, placebo-controlled, proof-of-concept study for treatment of CRSwNP. The purpose of this study is to assess the efficacy, safety, and tolerability of add-on therapy with subcutaneous lunsekimig in adult participants (aged 18 to 70 years, inclusive) with CRSwNP who are inadequately controlled on intranasal corticosteroid treatment. Participants with and without co-morbid asthma will be included in the study, and lung function will be assessed in both groups. The study duration will be up to approximately 40 weeks per participant, including 4 weeks of screening run-in period, 24 weeks of intervention period, and 12 weeks of follow-up.
NCT06776042
The goal of this clinical trial is to understand the mechanisms leading to olfactory dysfunction (OD) in chronic rhinosinusitis (CRS). The main questions it aims to answer are: * Is the type 2 inflammation impacting the olfactory epithelium regeneration, leading to OD? * Does a treatment interfering with one of the major T2 inflammatory cytokines, have an impact on the mechanisms of OD in CRS? Participants will undergo olfactory testing and nasal brushing before and after 3 months of treatment.
NCT04469439
This study will be a prospective, observational study of patients who undergo endoscopic sinus surgery for cystic fibrosis-related chronic rhinosinusitis (CRS). Individuals who do not undergo surgery but are treated medically for CRS will also be enrolled to serve as a control group. Outcomes analyzed will include pulmonary, quality of life, and others.
NCT03439865
The purpose of this pilot study is to explore wither ivacaftor in refractory CRS patients will demonstrate safety and tolerability; restore CFTR-mediated Cl- secretions as measured by EDSPD testing; produce detectable improvements in validated measures of CRS including the SNOT-22 questionnaire, Lund-MacKay CT scan grading, and Lund-Kennedy endoscopic scores; and provide beneficial effects on readily measured markers of sinonasal inflammation and infection (IP-10, IL-8, and Pseudomonas CFUs).
NCT06069310
The goal of this observational study is to learn about clinical and functional outcomes in patients with Chronic rhinosinusitis with nasal polyps and comorbid Severe Eosinophilic Asthma and patients with Chronic rhinosinusitis with nasal polyps only treated with mepolizumab compared to healthy controls. Participants will be asked to give nasal, blood and sputum samples before mepolizumab administration (T0) and at 3 (T3), 6 (T6) and 12 (T12) months after mepolizumab initiation The main aims are to identify airways microbiota modifications and differential gene expression after mepolizumab initiation. Researchers will compare: * Patients with Chronic rhinosinusitis with nasal polyps and comorbid Severe Eosinophilic Asthma * Patients with Chronic rhinosinusitis with nasal polyps only * Healthy subjects The research will address the following questions: 1. What are the prospective clinical and functional outcomes of mepolizumab treatment 2. What is the impact of mepolizumab therapy on the airways microbiota and how this may relate to a potentially reduced need for steroids 3. What are the host differential gene expression patterns and the immune/inflammatory (cytokines/chemokines) profile alterations in airways microenvironment and in systemic circulation in response to therapy 4. What are the associations between host and microbiome variables for building up diagnostic and predictive biomarker classifiers of responsive disease endotypes
NCT07534280
The objective of this phase I controlled clinical trial is to determine the safety and efficacy of Berry leaves \& Mango leaves mixture in symptomatic treatments on disease-related quality of life in adults with clinically diagnosed acute rhinosinusitis. Ten adult subjects, 18 to 70 years old, who meet the recommended criteria for acute rhinosinusitis, will be enrolled from Minia university ENT outpatient Clinic. Subjects will be advised to add Berry leaves \& Mango leaves herbal tea mixture and followed for one month with their routine therapy (an oral decongestant, a nasal saline spray, and an antitussive agent except analgesic). Subject outcomes will be assessed by telephone interview at 0, 3, 7, 10, and 28 days. The Quality-of-life outcomes are measured on Day 3, 10 and 28 with SNOT-16, a validated evaluative instrument.
NCT07528820
This study aims to examine three key aspects of chronic rhinosinusitis with nasal polyps (CRSwNP): inflammation, tissue structure (histopathology), and remodeling.
NCT07524127
This monocentric, interventional study (category RIPH2) aims to characterize the rheological properties of sinonasal secretions in patients with Chronic Rhinosinusitis with Nasal Polyps (CRSwNP). The primary objective is to determine differences in mucus viscosity between CRSwNP patients and a control group. By establishing a correlation between local rheology and systemic Type 2 inflammation biomarkers, the study seeks to develop a non-invasive, rapid "point-of-care" tool to refine patient phenotyping and improve the personalization of biological treatments.
NCT07498374
This study consists of two parts evaluating the efficacy and safety of a fully degradable sinus drug-eluting stent in patients with eosinophilic chronic rhinosinusitis with nasal polyps (ECRSwNP). Part A assesses the efficacy and safety of the stent when used immediately after functional endoscopic sinus surgery (FESS). Part B evaluates the stent in patients with early postoperative recurrence of ECRSwNP. The study aims to answer the following key questions: Does the use of the stent reduce the recurrence of nasal polyps? Can the stent reduce the need for oral corticosteroids? The fully degradable sinus drug-eluting stent is compared with intranasal corticosteroids (Part A) and oral corticosteroids (Part B) to determine whether it offers therapeutic benefit in the management of ECRSwNP. Participant Procedures: Part A: Participants will either receive the fully degradable sinus stent or daily intranasal corticosteroids for 6 months. Follow-up visits will occur at Week 2, Week 4, Week 8, Week 12, and Month 6 to record symptoms and adverse events. Part B: Participants will either receive the fully degradable sinus stent or oral corticosteroids (based on disease progression) for 6 months. Follow-up visits will be conducted at Week 2, Week 4, Week 8, Week 12, and Month 6 for symptom assessment and documentation of adverse events.
