Incidence of SARS-CoV-2 in people with cystic fibrosis in Europe between February and June 2020

Abstract

Background: Viral infections can cause significant morbidity in cystic fibrosis (CF). The current Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) pandemic could therefore have a serious impact on the health of people with CF (pwCF).

Methods: We used the 38-country European Cystic Fibrosis Society Patient Registry (ECFSPR) to collect case data about pwCF and SARS-CoV-2 infection.

Results: Up to 30 June 2020, 16 countries reported 130 SARS-CoV-2 cases in people with CF, yielding an incidence of 2.70/1000 pwCF. Incidence was higher in lung-transplanted patients (n=23) versus non-transplanted patients (n=107) (8.43 versus 2.36 cases/1000). Incidence was higher in pwCF versus the age-matched general population in the age groups <15, 15-24, and 25-49 years (p<0.001), with similar trends for pwCF with and without lung transplant. Compared to the general population, pwCF (regardless of transplantation status) had significantly higher rates of admission to hospital for all age groups with available data, and higher rates of intensive care, although not statistically significant. Most pwCF recovered (96.2%), however 5 died, of whom 3 were lung transplant recipients. The case fatality rate for pwCF (3.85%, 95% CI: 1.26-8.75) was non-significantly lower than that of the general population (7.46%; p=0.133).

Conclusions: SARS-CoV-2 infection can result in severe illness and death for pwCF, even for younger patients and especially for lung transplant recipients. PwCF should continue to shield from infection and should be prioritized for vaccination.

Abbreviations: CI=confidence interval, SARS-CoV-2=Severe Acute Respiratory Syndrome Coronavirus 2 Notes: All cases of SARS-CoV-2 in pwCF and the general population were PCR-confirmed. Incidence was calculated as (SARS-CoV-2 cases/number of people in the population)*1000. CF population size was from the 2018 ECFSPR report.

Incidence and rates of hospitalization and intensive care admission by age group and transplant status in people with cystic fibrosis compared to the general population. Notes: Confidence intervals shown as grey shaded area. People with CF aged ≥50 years were grouped together due to low numbers. The 24 countries included in age-banded analysis of incidence in people with CF and the general population were: Austria, Belgium, Croatia, Czech Republic, Cyprus, Denmark, France, Germany, Greece, Hungary, Ireland, Italy, Latvia, Lithuania, Luxembourg, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden. The 30 countries included in age-banded analysis of hospital and intensive care admission in people with CF and the general population were the 24 countries above plus Bulgaria, Estonia, Finland, Iceland, Malta, United Kingdom.
