Differences in Disease Expression Between Primary Ciliary Dyskinesia and Cystic Fibrosis With and Without Pancreatic Insufficiency

Although in our study PCD was similar to CF-PS, the lack of correlation between FEV1 and age, CT-TBS, and P aeruginosa infection in PCD suggests that impaired mucociliary clearance is not the only cause for inducing pulmonary damage in these diseases. Furthermore, a comparison of disease characteristics for PCD and CF should distinguish between CF-PI and CF-PS as different entities.
