Filter by:this study is aiming at learning more about primary ciliary dyskinesia (PCD) and tests that are used to diagnose this condition. One purpose of this study is to measure the level of nitric oxide in the nasal passages and examine how often the results correlate with other tests currently done to make the diagnosis.
The overall objective of this longitudinal, observational study is to provide information needed to inform the design of future interventional trials of respiratory exacerbation prevention and treatment in children and adults with primary ciliary dyskinesia (PCD).
Decreased pulmonary function, peripheral muscle strength, and exercise capacity were reported in primary ciliary dyskinesia (PCD) in recent studies. We aimed to investigate the data conducted between 10 July 2015 and 10 January 2015 of pulmonary function, respiratory muscle strength, exercise capacity, physical fitness, and activities of daily living (ADL) in PCD and healthy counterparts retrospectively at the first stage of the study and the effects of inspiratory muscle training on pulmonary function, respiratory muscle strength, and exercise capacity in PCD patients with decreased inspiratory muscle strength from the database recorded between 10 July 2015 and 10 January 2015 retrospectively at the second stage of the study.
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. The aims of this study are: 1. Correlation between nasal NO levels and distinct PCD genotypes 2. Determination of further parameters potentially associated with nasal NO levels in genotyped PCD individuals 1. course of clinical manifestations (e.g. neonatal distress, infections, bronchiectasis) 2. diagnostic results (HVMA, TEM, IF) 3. lung function outcome (FVC, FEV1)
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.
The main aim of the study is to evaluate upper extremity exercise capacity and muscle oxygenation in patients with primary ciliary dyskinesia. The secondary aim of the study is to evaluate respiratory function, respiratory muscle strength and endurance, peripheral muscle strength, balance, physical activity level and quality of life in patients with primary ciliary dyskinesia and compare all parameters with healthy controls.
This study investigates the use of hyperpolarized 129Xe magnetic resonance imaging (MRI) in children with primary ciliary dyskinesia (PCD) in detecting ventilation defects. The investigators will establish the feasibility and reliability of this test and how it changes compared to other pulmonary function tests.
Primary ciliary dyskinesia (PCD) is characterized by impaired airway clearance and mucus stagnation. This results in recurrent upper and lower respiratory tract infections often leading to chronic inflammation and, if not treated early and properly, to irreversible functional and structural changes of the respiratory tract. As there is no causal treatment of PCD yet, airway clearance techniques (ACT) provide fundamental care for these patients. Simeox is a new airway clearance device, recently developed by the French company PhysioAssist. This technology is based on pneumatic vibrations generated by the device itself. Vibrations are induced by rapidly alternating between atmospheric and negative pressure as the patient exhales, providing the most effective clearance of mucus from the lungs. Vibrations of different intensity and frequency are known to alter the rheological properties of mucus in the airways, whilst the negative pressure during exhalation helps to mobilise and drain the mucus to the central bronchi. Although there have not yet been any evidence based papers published clarifying the effect of Simeox specifically in patients with PCD, using up-to-date information, experience, and positive feedback from our patients, we assume that there could be a significant benefit for the effectiveness of ACT.

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
