Filter by:During this project, the investigators want to explore in vitro changes in basal cells and the crosstalk with residing immune cells as potential pathogenic mechanisms in CRSwNP vs healthy controls by using surgically resected patient samples.
Chronic rhinosinusitis (CRS) is a condition of persistent sinonasal mucosal inflammation which affects 11.9% of the US population. Mepolizumab is newly approved to treat chronic rhinosinusitis with nasal polyps (CRSwNP, the spaces inside nose and head are swollen and inflamed) and acts booking interleukin-5 (IL-5) a protein implicated in the inflammatory process. We aim to use Single-cell RNA sequencing (RNA-Seq, a method of genetically 'barcoding' cells to allow gene expression to be profiled at the level of individual cells) to study the effects of IL-5 blockade on the generation and maintenance of nasal adaptive immune responses, in CRS subjects.
The aim of the present study will be to evaluate in conscripts at the military induction board the prevalence of rhinosinusitis, the prevalence of HPV vaccinations, the prevalence of hearing impairments and the prevalence of long-COVID symptoms and further, to evaluate different factors that influence on the one hand the prevalence (urban-bred, non-urban-bred) and on the other hand symptoms (ENT-surgeries in medical history). Further, we want to evaluate if there is a correlation between subjective symptoms and apparated-based diagnostic investigations. Therefore, questionnaires and data of medical examinations, aquired routinely at the military induction board, will be analysed.
The primary purpose of the study is to evaluate the efficacy of brensocatib at 10 and 40 milligrams (mg) once daily (QD) compared with placebo in improving clinical symptoms of CRSsNP.
Rhinitis is a type of upper respiratory infection with a common nasal pathology especially in Southeast Asia, which is characterized by the presence of one or more of the following symptoms: itchy nose, sneezing, runny nose, and nasal congestion. Other symptoms occasionally experienced include headache, excessive pain reaction, cough, fever. Rhinitis can be idiopathic or due to a variety of causes, including allergens, medications, endocrine/metabolic, infectious, inflammatory, and abnormal nasal structures. The treatment of acute rhinosinusitis and allergic rhinitis in hospitals is currently carried out according to the general professional guidance of the Vietnam Ministry of Health. Most patients are prescribed corticosteroids, antihistamines, and antibiotics for immediate decongestion and anti-inflammatory effects. Current concerns about antimicrobial resistance (AMR) as well as side effects of corticosteroids and antihistamines have led to an urgent need for a naturebased next generation therapeutic approach that is safe, effective and helps in addressing the issues of AMR. The goal of this interventional study is to evaluate the safety and efficacy of postbiotic nasal spray using inert bioparticles of Bacillus subtilis DSM32444 in treatment of acute rhinosinusitis; and to compare the efficacy against Neomycin/Dexamethasone//Xylometazoline administered as a nasal spray as an adjunct to Amoxicillin/Clavulanate standard treatment in patients with acute rhinosinusitis. Patients with acute rhinosinusitis who give consent to participate in the study will be randomly assigned in a 1:1 ratio to one of two groups using postbiotic of Bacillus subtilis DSM32444 nasal spray ("Sperovid") or Neomycin/ Dexamethasone nasal spray for a period of 10 days. Investigators will compare whether the nasal spray using postbiotic Bacillus subtilis DSM32444 has similar efficacy as compared to Neomycin/Dexamethasone/Xylometazoline nasal spray as an adjuvant therapy along with the standard Amoxicillin/Clavulanate regimen in patients with acute rhinosinusitis based on time to improvement of rhinosinusitis symptoms.
Rhinitis is a type of upper respiratory infection with a common nasal pathology especially in Southeast Asia, which is characterized by the presence of one or more of the following symptoms: itchy nose, sneezing, runny nose, and nasal congestion. The treatment of acute rhinosinusitis and allergic rhinitis in hospitals is currently carried out according to the general professional guidance of the Vietnam Ministry of Health. A common treatment regime for patients with rhinosinusitis in Vietnam includes a combination of steroids and antibiotics (Neomycin/Dexamethasone/ Xylometazoline) administered as a nasal spray, in adjunct with Amoxicillin/clavulanate 875/125 mg taken orally every 12- hours. The duration of treatment for patients is about 10 days depending on the severity of the disease. During the treatment period, a change in the systemic antibiotic regimen is necessary if the observations after 3 to 5 days of treatment do not show signs of a satisfactory response. Current concerns about antimicrobial resistance (AMR) as well as side effects of corticosteroids and antihistamines have led to an urgent need for a naturebased next generation therapeutic approach that is safe, effective and helps in addressing the issues of AMR. There have been multiple research studies supporting the efficacy of bacterialbased approaches in the prevention of viral respiratory infections, and that have potential for treatment. For use in the respiratory tract, it is necessary to have a completely sterile product to ensure safety in the long-term and there is a need for safety assessment of products both in animal models and human studies. This phase of the study aims to evaluate the safety in humans of a nasal spray using a postbiotic preparation of Bacillus subtilis DSM32444 and that is a sterile inert bioparticle.
This study is a pragmatic, real-life, observational study recruiting adult patients with chronic rhinosinusitis with nasal polyposis who are eligible to start biologicals as standard treatment. The aim of this study is to observe the long-term outcomes of biologicals in CRSwNP patients with or without comorbid asthma in 'real life'. Moreover, the investigators will gain insight into the mechanisms of biologicals in the local and systemic immunity of these patients and investigate novel local and systemic biomarkers and predictors of response.
This is a parallel group, Phase 3, 2-arm study for treatment. The purpose of this study is to evaluate dupilumab subcutaneous (SC) injections compared to placebo in Chinese adult participants with CRSwNP, on a background therapy with intranasal corticosteroids (budesonide nasal spray). Study details include: - The study duration will be up to 40 weeks. - The treatment duration will be up to 24 weeks. - The number of visits will be 7.
This study aimed to evaluate the efficacy of Pulsed electromagnetic field (PEMF) for Chronic sinusitis in a randomized, double-blind, placebo-controlled trial.
This study aimed to evaluate the efficacy of low-level laser therapy (LLLT) for Chronic sinusitis in a randomized, double-blind, placebo-controlled trial.
