Assessing COVID-19 antibody responses in people with cystic fibrosis

COVID-19 Antibody Responses In Cystic Fibrosis: CAR-CF

Centro Hospitalar Universitário Lisboa Norte · NCT06274840

What this trial studies

This observational study aims to evaluate the presence of SARS-CoV-2 antibodies in individuals with cystic fibrosis (pwCF) over a two-year period. It will involve repeated blood sampling at various intervals to monitor antibody levels and assess any clinical implications related to COVID-19 in pwCF. Participants will be recruited from pediatric and adult cystic fibrosis centers across Europe, and their clinical data will be collected alongside routine care visits. The study seeks to understand whether pwCF have unique immune responses to COVID-19 and how this affects their cystic fibrosis condition.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals of any age with a confirmed diagnosis of cystic fibrosis who can provide informed consent.

Not a fit: Patients who refuse to give informed consent or have contraindications to venepuncture will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into the immune response of pwCF to COVID-19, potentially leading to improved care strategies for this vulnerable population.

How similar studies have performed: Other studies have explored immune responses to COVID-19 in various populations, but this specific focus on cystic fibrosis is relatively novel.
