Evolving Nutritional Needs in Cystic Fibrosis

Area of Science:

• Medical Science
• Nutritional Science
• Pulmonology

Background:

• Cystic fibrosis (CF) traditionally presents significant nutritional challenges.
• The advent of highly effective modulator therapies (HEMT) is altering the disease's natural progression and nutritional impact.
• Understanding these changes is crucial as HEMT are now approved for younger pediatric populations.

Purpose of the Study:

• To review current research on the evolving nutritional health of individuals with CF.
• To analyze the specific impacts of HEMT on various nutritional and metabolic aspects of CF.
• To provide insights into the long-term nutritional implications of HEMT in CF care.

Main Methods:

• Comprehensive literature review of existing studies on CF and HEMT.
• Analysis of research data concerning anthropometrics, body composition, and energy expenditure.
• Examination of studies on pancreatic function, metabolic disorders, and micronutrient status in CF patients on HEMT.

Main Results:

• HEMT are associated with significant shifts in anthropometric measures and body composition.
• Impacts on exocrine and endocrine pancreatic function, including CF-related diabetes, are being observed.
• Changes in vitamin and mineral status, alongside considerations for pregnancy and lung transplantation, are noted.

Conclusions:

• HEMT are leading to more heterogeneous nutritional phenotypes in CF, even in those with genetic mutations associated with worse prognosis.
• Ongoing research is vital to fully understand and manage the long-term nutritional consequences of HEMT across the lifespan.
• Personalized nutritional strategies will be increasingly important for optimizing health outcomes in individuals with CF receiving HEMT.
