| Pathologie, précisions | Primary Ciliary Dyskinesias (PCD) are respiratory diseases related to a constitutional abnormality of the cilia that affects the axonema, a structure common to cilia and flagella. PCDs provok upper and lower airway infections, secondary to alterations in muco-ciliary purification, which are classically manifested in childhood. These respiratory infections result in recurrent bronchopulmonary disease and rhinosinusitis, progressing to bronchial dilation and nasal polyposis, respectively. In half of the cases, there is a reverse rotation of the viscera (situs inversus), resulting in Kartagener's syndrome, defined by the triad of bronchiectasis, chronic sinusitis and situs inversus, which therefore constitutes a subgroup of PCDs. The first and most common ciliary abnormality, found in patients with PCD, corresponds to an absence of the outer dynein arms that carry the ATPase activity essential for ciliary movement. Many other ultrastructural abnormalities of the cilia were subsequently described in the context of PCDs. Most affected men are sterile due to immobility of the flagellum of the spermatozoa, which then present the same ultrastructural defect as that of the respiratory cilia. The incidence of PCDs in the general population is estimated to be 1/16000. The transmission of PCDs is classically autosomal recessive, with the frequency of affected individuals being much higher in populations where there is a high degree of inbreeding. |

| Informations complémentaires concernant la constitution de l'échantillon |
Depending on their symptomatology, the initial management of patients suspected of PCD is carried out in a paediatric, ENT, adult pneumology, paediatric pneumology, or reproductive biology department that undertakes etiological explorations, in particular ciliary investigations that make it possible to confirm the diagnosis of PCD.
The RaDiCo-DCP cohort will consist of 300 prevalent and incident patients, both paediatric and adult, who will be followed for 5 years after their inclusion in the study. |
| Objectif de la base de données | |
| Objectif principal | The main objective is to identify in a large cohort of PCD patients, early predictors of severity in order to improve personalized patient management. |
| Critères d'inclusion |
All prevalent patients and incidents included in the RaDiCo-DCP cohort must:
• Have a confirmed diagnosis of PCD based on at least one of the following diagnostic criteria: Kartagener syndrome (association of chronic sinusitis, bronchiectasis and situs inversus), and/or evidence of specific abnormalities of the ciliary ultrastructure, and/or identification of unambiguous mutations in a PCD gene. • Have at least one annual follow-up visit in accordance with standard practice. Patients who meet the following criteria will not be included: • Patient with an unconfirmed diagnosis of PCD; • Patient with a concomitant progressive pathology that may interfere with the evaluation of PCD-related manifestations. |
