INTRODUCTION On the 15th of November 2020, the National Centre for Rare Diseases of the Italian National Health Institute, clinicians of the Italian National Referral and Support Centres for Cystic Fibrosis, Children’s Hospital “Bambino Gesù”, Italian Cystic Fibrosis Society, Italian League for Cystic Fibrosis renewed the agreement about CF data flow for a 3-year period. The possibility to access data by third parties is among the most important innovation introduced within the agreement. OBJECTIVES Aim of the present Report is to improve the know-how of cystic fibrosis (CF) through a better characterization of Italian patients. Furthermore, the present Report aims at improving thecare of CF patient. In particular, this Report should contribute to the following objectives: • to analyse the medium- and long-term clinical and epidemiological trends of the disease; • to identify the main healthcare needs at regional and national level, in order to contribute to the healthcare programmes and to the distribution of resources; • to compare Italian data with international ones. DESIGN Analyses and results described in the present Report are referred to patients currently followed at the Italian National Referral and Support Centres for Cystic Fibrosis in the 2017-2018 period. Data were sent by clinical Centres through a newcommitted software. Data underwent a double quality control (QC): The first is automatically performed by the software (quantitative QC), the second is performed at a European level (before the inclusion of the Italian data within the European Cystic Fibrosis Registry). These QCs assure the completeness and the accuracy of data as well as their consistency with the European core data. SETTING AND PARTICIPANTS A total of 29 CF Centres (referral and support centres and Bambino Gesù Children’s Hospital CF centre) sent their data referred to 2017-2018 years to ICFR. CF Centres of Verona, Messina, and Palermo do not use the new ICFR software; however, their data are firstly collected in a centralized manner, then sent to the European Registry. Data from support centres of Treviso and Rovereto are sent through Verona CF Center. Data from Sardinia Center are still missing. RESULTS The present Report has been organized into 10 sections. 1. Demography: In the ICFR, 5,565 CF patients were registered in 2017 and 5,501 in 2018; median age was 21.4 years in 2017 and 21.2 years in 2018. Prevalence was 9.20/100,000 residents in Italy in 2017 and in 2018. Male percentage was 51.65% in 2017 and 2018, CF distribution by age range showed higher frequency in patients aged 7 to 35 years. Adult patients (aged more than 18 years) were 56.4% on average in 2017 and 2018. 2. Diagnoses: Most of the CF patients were diagnosed before two years of age (median value 66.4%); a significant percentage of patients (21.6% in 2017 and 18.3% in 2018) was diagnosed in adult age. 3. New diagnoses: New diagnoses were 162 in 2017 and 142 in 2018. Estimated incidence was 1/5.214 living births in 2017 and 1/5.442 in 2018. 4. Genetics: 99.8% of patients underwent genetic analyses and in 97.1% of these patients a mutation in Cystic Fibrosis Transmembrane Regulator (CFTR) gene was identified. The F508del mutation was the most frequent (44.6% in 2018). Furthermore, 16.3% of patients in 2017 and 16.9% of patients in 2018 had at least one ‘residual function’ mutation. At least one gating mutation is present in 3.3% of Italian patients. Finally, 20.5% of patients had at least one stop codon mutation (class 1). 5. Lung function: Percent predicted FEV1 (Forced Expiratory Volume in the first second) progressively declined before adult age, in accordance with the natural history of the disease. The majority of paediatric patients (6-17 years of age), i.e., 86.70% in 2017 and 90.50% in 2018, had percent  predicted FEV1 ≥70%; whereas paediatric patients with a FEV1% ≤40% are less than 2% in the 2017-2018 period. 6. Nutrition: The two most critical periods are the first 6 months of life and adolescence. Prevalence of malnourished adolescent males (12-17 years of age) is higher than the prevalence observed in females. Increasing percentages of adult female patients with a suboptimal BMI value (39.1% and 36.1%, respectively, in 2017 and 2018) are observed. 7. Complications: In 2018, CF-related liver disease without cirrhosis was the main complication both in patients aged less than 18 years (17.0% on average) and in adults (31.5%). CF-related diabetes was also frequent in CF adults (23.4%). 8. Transplantation: In 2017-2018, 83 patients received a double-lung transplantation. Median and range of age were 29.3 years (11.8-60.2) in 2017 and 29.1 (7.8-45.6) years in 2018. Median waiting times for lung transplantation in the two considered years were 8.6 and 7.7, respectively. 9. Microbiology: Percentage of adult patients with chronic Pseudomonas aeruginosa infection was 51.3% in 2017 and 46.3% in 2018 vs 15.6% in 2017 and 10.2% in 2018 in paediatric age. Staphylococcus aureus infection is present in 53.4% and 53.5% of adult patients in 2017 and in 41.6% and 37.5% of paediatric patients in 2018. 10. Mortality: A total of 89 patients died in the 2017-2018 period (49 females); median age at death was 33.9 years in 2017 and 35.8 years in 2018 (transplanted patients are not included). CON CLUSION S The present report shows that the Italian CF population is growing (4,159 in 2010 vs 5,501 in 2018; +1,342). Quality of data collected has been improved by the drastic reduction of missing data, thanks to the new software for data collection. Median age of patients increased in the 2010-2018 period (17 years in 2010 vs 21.2 years in 2018). Paediatric death is a very rare event. A very low percentage of paediatric  population was characterized by severe lung disease (FEV1% <40). Prevalence of adult patients is increasing (56.4% in 2018). Age at diagnosis is decreasing (4.2 months in 2017 vs 3.8 months in 2018). Median age at death (transplanted patients not included) was 33.9 in 2017 and 35.8 in 2018. RIFC is completely compliant with the GDPR (UE 2016/679 regulation) and its role in national and international CF communities is confirmed.
