Brief Summary

The Ear-Nose-Throat (ENT) Prospective International Cohort of patients with Primary Ciliary Dyskinesia (EPIC-PCD) is a prospective observational clinical cohort study, set up as a multinational multi-centre study. It is embedded into routine patient care of participating reference centres for PCD and patients keep being managed according to local procedures and guidelines.

Detailed Description

The EPICD-PCD is hosted at the Institute of Social and Preventive Medicine (ISPM) at the University of Bern, Switzerland. Research is performed in close collaboration with all data contributors. This study aims to characterise ENT disease in PCD patients and its association with lower respiratory disease, and to identify determinants of its prognosis.

The investigators aim to:

1. Assess the prevalence and severity of sinonasal and otologic symptoms and the frequency and range of signs and physiological findings assessed during standardised ENT physical examination, and describe differences by age;

2. Study the association of sinonasal and otologic disease with lower respiratory disease in PCD patients;

3. Identify determinants of disease course and prognosis of sinonasal and otologic disease in PCD patients.

Study design:

The EPIC-PCD is a prospective observational clinical cohort study, set up as a multinational multi-centre study. It is embedded into routine patient care of participating reference centres for PCD and patients will keep being managed according to local procedures and guidelines.

Patients with PCD are followed regularly at each centre, at 3-month to 6-month intervals. Each patient undergoes a detailed ENT sinonasal and otologic examination by ENT specialists, at minimum once a year, during a programmed follow-up visit. Additional ENT examinations are performed if indicated during in-between follow-up visits. Patients will not be subjected to additional invasive measurements solely for the purposes of the study.

What information is collected:

The study collect clinical data from patients assessment at regular consultations at the outpatient clinics.

For the collection of clinical data, participating centres will use FOLLOW-PCD, a disease-specific form for standardised prospective data collection during routine clinical follow-up of PCD patients.

Study database:

The EPIC-PCD database is web-based, using the Research Electronic Data Capture (REDCap) platform developed at Vanderbilt University. REDCap is widely used in academic research and allows data entry and extraction in various formats.

How to participate:

Centres that wish to participate to the project and contribute data can contact the EPIC-PCD managing centre to sign a data delivery agreement. They then will receive a password to access the online software REDCap and they will be able to enter their data directly. They can also upload follow-up data or add additional patients at a later time point.

Funding:

The setting up of the EPIC-PCD (salaries, consumables and equipment) was funded by the Swiss National Science Foundation. Data collection and management at each site was funded according to local arrangements. Most participating researchers and data contributors participate in the European Respiratory Society Clinical Research collaboration "Better Evidence to Advance Therapeutic options for PCD" (BEAT-PCD) (https://beat-pcd.squarespace.com/). Infrastructure is provided for free by the University of Bern, where the data are pooled and stored.
