PCD

Research Genetic Testing for Primary Ciliary Dyskinesia Using a Panel of Genes (5905), IRB Study #14-1225

Sponsor: NIH
PI: Mike Knowles, MD

Primary ciliary dyskinesia (PCD) is a Mendelian recessive, genetically heterogeneous disorder with defective mucociliary clearance (MCC), chronic oto-sino-pulmonary disease with bronchiectasis, and organ laterality defects in ~50% of patients (Kartagener Syndrome). Despite the need for early diagnosis and expert clinical care in PCD, establishing a diagnosis remains a major challenge, based on the traditional approaches of using electron microscopy and/or ciliary waveform analysis to define abnormalities of ciliary ultrastructure and/or function. The goal for this study is to determine whether a multi-gene (n=30) genetic test panel to confirm a diagnosis of PCD will identify as many as 70% of PCD patients. If this genetic test panel is successful, it will revolutionize the diagnostic approach in PCD, and lead to early identification and initiation of clinical monitoring and treatment.

Longitudinal Study of Primary Ciliary Dyskinesia: Participants 5-18 Years of Age (5901), IRB Study # 05-2997

Sponsor: NIH
PI: Margaret Leigh, MD

Mucociliary clearance (MCC) is the primary defense mechanism for the lung. Inhaled particles (including microbial pathogens) are entrapped in mucus on the airway surface then cleared by the coordinated action of cilia. The volume and composition of airway surface liquid (ASL) influence the efficiency of ciliary function and MCC. Genetic diseases of MCC include disorders in ciliary function (primary ciliary dyskinesia, PCD), and ion transport (cystic fibrosis). The purpose of this longitudinal study protocol is to define age-related prevalence of phenotypic characteristics and the progression of key features of lung disease in subjects with Primary Ciliary Dyskinesia (PCD).

Rare Genetic Disorders of the Airways: Cross-sectional Comparison of Clinical Features, and Development of Novel Screening and Genetic Tests (5902), IRB Study # 05-2979

Sponsor: NIH
PI: Mike Knowles, MD

Mucociliary clearance, in which mucus secretions are cleared from the breathing airways, is the primary defense mechanism for the lungs. Inhaled particles, including microbes that can cause infections, are normally entrapped in mucus on the airway surfaces and then cleared out by the coordinated action of tiny hair-like structures called cilia. Individuals with primary ciliary dyskinesia, variant cystic fibrosis, and pseudohypoaldosteronism have defective mucociliary clearance. The purpose of this study is to collect clinical and genetic information about these three airway diseases to improve current diagnostic procedures.

CTRC-2589 Early Onset and Progression of Primary Ciliary Dyskinesia Lung Disease Prior to 10 Years of Age (5903), IRB Study # 08-0764

Sponsor: NIH
PI: Margaret Leigh, MD

Primary ciliary dyskinesia (PCD), also known as Kartagener syndrome, is a genetic disorder of the cilia, which are microscopic hair-like cells. Cilia work to keep the respiratory system clean by moving mucus that contains debris to the large airways, where it can be coughed out. People with PCD have cilia that do not move properly and therefore are not effective in cleaning the respiratory system. This study will determine when PCD starts and how it changes over time, specifically in terms of how well the lungs work, what germs grow in lung secretions, and how the lungs look on computed tomography (CT) scans.

Cross-Sectional Characterization of Idiopathic Bronchiectasis (5904), IRB Study #10-1523

Sponsor: NIH
PI: Mike Knowles, MD

Bronchiectasis is a type of lung condition in which the lungs' airways are abnormally stretched and widened. This stretching and widening makes it difficult for mucus and other substances to move out of the lungs, encouraging the growth of bacteria and leading to breathing problems or infection. Bronchiectasis can be caused by genetic disorders or diseases such as tuberculosis or rheumatoid arthritis. Researchers are interested in developing better ways to diagnose and treat a lung problem called idiopathic or unexplained bronchiectasis. The goal of this study is to better describe the physical characteristics, radiographic patterns, and airway microbiology of unexplained bronchiectasis and to look for possible genetic links or risk factors.

Mortality Prediction Model for Prolonged Mechanical Ventilation (PRO-VENT)

Sponsor: UNC
Principal Investigator: Shannon Carson, MD

Patients requiring prolonged mechanical ventilation (PMV) often survive the initial severe stages of their illness, but remain dependent on life support systems. Long-term prognosis is often confusing or uncertain for patients, families, and physicians. In order to help clarify prognosis for these complicated patients, a prognostic model that identifies PMV patients who have a high risk of mortality was developed and validated in a multi-center study. Currently, the study continues to identify variables for this model to predict prognosis earlier on in a patient’s stay, as well as predict functional outcomes using both qualitative and quantitative methodology.
