    The term “primary” was used to distinguish this condition from secondary ciliary abnormalities caused by inflammation and infection. [frontiersin.org]

    If the mucus cannot be moved, a vicious cycle of mucus over-production, inflammation and infection occurs. Repeated and chronic infections lead to inflamed and damaged airways, a condition known as bronchiectasis. [pcdaustralia.org.au]

    To overcome diagnostic difficulties related to secondary abnormalities caused by infection and inflammation, HVMA as well as transmission electron microscopy (TEM; see below) or immunofluorescence analysis (IF; see below) can be performed additionally [ciliajournal.biomedcentral.com]

    It is of interest that, as with CF, spontaneously expectorated sputum reveals predominantly neutrophilic inflammation [ 82 ]. Evidence is awaited to support the use of anti-inflammatory agents such as corticosteroids and azithromycin. [breathe.ersjournals.com]

    The important sign is that of a persistent “wet” sounding cough. Especially if such a cough persists for more than 8 weeks or symptoms return when antibiotic treatment is stopped. [czytelniamedyczna.pl]

    In addition, PCD patients develop a chronic cough and frequently have clinically severe respiratory infections. Since airway cleaning is disturbed, not only the respiratory tract in the lung but also the nasal passages have chronic obstruction. [campus.uni-muenster.de]

    Lower respiratory tract The predominant symptom in these patients is chronic cough, usually productive. Wheezing is not common. Recurrent pneumonia is a frequent finding in the history of primary ciliary dyskinesia patients. [jped.com.br]

As the pathophysiology of CF and PCD are fundamentally different such extrapolation is unsatisfactory. [breathe.ersjournals.com]

Many genes participate in the construction of a cilium, and an error in any one of them will prevent the cilia from working properly. The inheritance in most cases is autosomal recessive. [ommbid.mhmedical.com]

Frustratingly for the patient, this can cause delays by weeks or even months, but preventing brushings which will not result in a conclusive outcome is time and cost effective for the NHS, and it prevents repeated sampling for the patient. [journals.rcni.com]
