Italian Cystic Fibrosis Register - Report 2010

The Italian National CF Registry (INCFR) is based on the official agreement between the clinicians of the Italian National Referral Centers for Cystic Fibrosis and the researchers of the Istituto Superiore di Sanità (National Center for Rare Diseases; National Center for Epidemiology, Surveillance and Health Care Promotion). OBJECTIVES The main aim of INCFR is to contribute to the improvement in CF patients health care and clinical management through: i. the estimates of CF prevalence and incidence in Italy; ii. the analyses of medium and long term clinical and epidemiological trends of the disesase; iii. the identification of the main health care needs at regional and national level to contribute to the Health Care programmes and to the distribution of resources. MATERIALS AND METHODS Analyses and results described in the present Report are referred to patients in charge to the Italian National Referral Centers for Cystic Fibrosis in 2010. Data were sent by Centers by means of a specific software (Camilla, Ibis Informatica). The Italian National Referral Centers for Cystic Fibrosis sent a total of 5,271 individual records; 1,112 records were excluded from the analyses due to restricted inclusion criteria. The total number of patients included in INCFR for analyses is 4,159. RESULTS INCFR database includes all prevalent cases at 1th January 2010 as well as all new diagnoses done in 2010. The present Report has been organized into 9 sections. 1. Demography: estimated 2010 CF prevalence was 7/100,000 residents in Italy; 52% of the patients were male, CF distribution showed higher frequency in patients aged 7 to 35 years. In 2010, 48.9% of the patients were more than 18 years old. 2. Diagnoses: most of the CF patients were diagnosed before two years of age (66.7%); a significant percentage of patients (11.4%) was diagnosed in adult-age. 3. New diagnoses (2010): new diagnoses were 168. Sixty-five percent of them was diagnosed before the second year of age and 17%in adulthood. No differences were observed between male and female. Incidence at birth was estimated 1/4,854 living births. 4. GENETICS: in 95.9% of patients, 2 (or more) CFTR mutations were identified. [delta]508F mutation was the most frequent (45.1%). 5. Respiratory function: analyses were performed on 2,966 out of 3,341 patients aged 7 years or older. FEV1 (Forced Expiratory Volume in the first second) scores progressively decreased before adult age, in accordance with the natural history of the disease. 6. Nutrition: most critical periods are during the first 6 months of life and during adolescence. Fourteen per cent of the patients within 2-18 years resulted malnourished. From 18 years onwards, optimal BodyMass Index (BMI) values were detected in 36.5%of males and in 28%of females. BMI also improved during age. 7. Transplantation: in 2010, 20 patients (10 males and 10 females) were bi-pulmunary transplanted; age was comprised between 11 and 46 years, median age at transplantation was 27.5 years. Eleven out of the 20 patients resulted still alive on the 31th December 2010. 8. Microbiology: analyses were performed on 3.272 patients (887 did not report these data) and were exclusively referred to tests performed in 2010. A percentage of 34 patients, younger than 18 years of age, was characterized by the presence of Pseudomonas aeruginosa compared to 61.8% of the older patients. Prevalence of Burkholderia Cepacia was 0.8% in patients aged up to 17 years; in patients aged more than 17 years, prevalence was 6.8%. Staphylococcus aureus meticillino sensitive prevalence was not correlated with patients' age. 9. MORTALITY: 34 patients aged from 0 to 45 years died in 2010 (16 males and 18 females). Respiratory insufficiency was the main cause of death (73.5%). CONCLUSIONS The report aims at being an instrument for CF community, with particular attention to the needs of patients and their families. Information collected within INCFR are an important starting point for further studies from health care perspectives. Finally, INCFR represents an important tool to foster research and innovative treatment for CF, as the rareness of the disease is a constraint to clinical trials and other studies set-up. A significant subset of data are regularly sent to the European Registry of Cystic Fibrosis.
