View clinical trials related to Primary Ciliary Dyskinesia.
Filter by:Though common, morbidities related to upper airway disease in primary ciliary dyskinesia (PCD) and primary immunodeficiencies (PID) have not been fully characterized. These conditions can be difficult to distinguish due to their overlapping phenotypes. The sinonasal and middle ear features are often identified as most problematic by patients and their families, and optimal, highly effective treatment regimens have not been established. The main objective of this project is to characterize and compare the upper airway phenotypes in individuals with confirmed diagnosis of PCD and PID, and to collect critical data to inform the design of future clinical trials of treatment of the upper airway diseases. The investigators anticipate that these investigations will discern the clinical, anatomical, and pathophysiological phenotypes of paranasal sinus disease in PCD and PID, identifying disease endpoints and biomarkers that differentiate these two overlapping disorders. Findings from these studies will also enhance our understanding of middle ear disease and associated hearing loss in a cross-sectional cohort of patients with PCD and PID. Ultimately, the long-term goal of our Consortium is to elucidate underlying phenotypes and genotypes of these diseases, potentially leading to novel therapeutics that will improve the lives of affected individuals. Given the COVID pandemic, certain procedures will have the option to be converted to telehealth visits to ensure compliance with local guidelines and participant safety.
The purpose of this study is to measure mucociliary clearance (MCC) in groups of subjects with the disease Primary Ciliary Dyskinesia (PCD) caused by mutations in different genes, and compare to healthy subjects. Some of these genes are associated with a milder clinical phenotype. This study seeks to determine if the milder phenotype is a result of mutations in a set of specific genes. The hypothesis is that subjects with PCD caused by mutations in the milder group will maintain a low, but significant rate of mucociliary clearance, while patients with mutations in genes in the more severe group will have a complete absence of mucociliary clearance. These studies will help inform future treatment strategies.
Primary Ciliary Dyskinesia (PCD) is a rare genetic disorder characterized by dysfunction of motile cilia associated with recurrent infections of the airways, laterality defects (Situs inversus totalis in about 50% of cases) and fertility problems. At present, mutations in > 45 genes associated with PCD and mucociliary clearance disorders have been identified, representing most likely two thirds of all human cases. Aim of this study are: - Correlation between genotype and lung function of patients with genetically confirmed PCD in an international cohort on a longitudinal basis - Determination of further parameters, such as body mass index (BMI), possibly associated with lung function in genetically confirmed PCD patients
The investigators will utilize a systematic approach for the diagnostic evaluation of patients to identify characteristics which may distinguish between Primary Immunodeficiency (PID) disorders versus Primary Ciliary Dyskinesia (PCD).
The Ear-Nose-Throat (ENT) Prospective International Cohort of patients with Primary Ciliary Dyskinesia (EPIC-PCD) is a prospective observational clinical cohort study, set up as a multinational multi-centre study. It is embedded into routine patient care of participating reference centres for PCD and patients keep being managed according to local procedures and guidelines.
The COVID-PCD is a participatory research project that aims to study how COVID-19 affects people with primary ciliary dyskinesia (PCD). The study is advertised through patient support groups and participants register online and answer a baseline questionnaire with details on PCD diagnosis, habitual symptoms, and COVID-19 episodes occurring before study entry. A short weekly follow-up questionnaire includes questions on incident SARS-CoV-2 infections, current symptoms, social contact behaviour, and physical activity. Occasionally, participants receive extra questionnaires focused on special topics. The study is hosted at the University of Bern and recruitment started on May 30th, 2020.
The purpose of this study is to determine the effect of a dietary supplement rich in nitric oxide (NO) on nasal nitric oxide and fractional exhaled nitric oxide (FeNO),on ciliary beat frequency assessed by high-speed digital video microscopy and on lung function assessed by spirometry in normal patients and patients with Primary ciliary dyskinesia (PCD).
Whole genome sequencing of Korean patients with idiopathic bronchiectasis and their family will perform to identify disease-causing variants.
This is a study evaluating the utility of current Primary Ciliary Dyskinesia (PCD) diagnostic tests, including nasal nitric oxide testing.
The Swiss Primary Ciliary Dyskinesia (PCD) Registry is a national patient registry that collects information on diagnosis, symptoms, treatment and follow-up of patients with PCD in Switzerland and provides data for national and international monitoring and research.
