Characterizing the Upper Airway Manifestations in Primary Ciliary Dyskinesia and Primary Immunodeficiencies

Plain-language summary

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.
