Risk of CFTR-related disorders and cystic fibrosis in an Italian cohort of CRMS/CFSPID subjects in preschool and school age

Conclusion: Most Italian preschool and school-aged children with CFSPID did not have a conclusive diagnosis, and progression to CF was unlikely in children  >  6 years of age. An annual follow-up could be indicated to identify early evolution in clinical features consistent with a CFTR-RD.What is Known:• Cystic Fibrosis newborn screening identifies also subjects with an inconclusive diagnosis (CFSPID).• Over time a variable percentage of CFSPIDs will be diagnosed as CF.• Little data is available on CFSPIDs with a follow-up period of more than six years.What is New:• 80% of Italian preschool and school-age CFSPIDs not have a conclusive diagnosis.• Italian preschool and school-age CFSPIDs have normal lung function and are pancreatic sufficient.• Annual follow-up after 6 years is recommended in CFSPID with abnormal LCI2.5 or with a CF-causing variant in trans with a VVCC.
