Historically, malnutrition and early mortality were considered inevitable consequences of cystic fibrosis (CF). However, implementation of newborn screening, nutrient supplementation, enteric-coated pancreatic enzymes, novel therapies, and improved respiratory care has continued to increase the life expectancy for those with CF. This increased life expectancy is accompanied by varied nutritional profiles and CF-related chronic complications requiring specific nutritional recommendations. An understanding of CF and its common physiological problems offers the opportunity to provide appropriate intervention and support to fulfill these priorities.

The purpose of this course is to provide an up-to-date review of the basics of CF pathology, relative nutritional considerations, and guidelines. Nutritional science and our understanding of the biochemical aberrations in CF are changing at an exponential rate. Using evidence-based concepts and insights from peer-reviewed research articles, it is expected that the learner will take away a stronger understanding of nutritional requirements in CF and of interventions that may improve outcome and quality of life. This course is appropriate for respiratory therapists, dietitians, pediatric and cardiopulmonary nurses, and other professionals interested in learning about current research and practice geared to improving nutritional outcomes in CF.


Course Objectives

  • Demonstrate an understanding of the etiology of cystic fibrosis (CF)
  • Recognize common symptoms of CF
  • Identify causes of nutritional deficiencies in CF
  • Identify markers that indicate pancreatic insufficiency (PI)
  • Assess for signs and symptoms of common nutritional deficiencies in CF
  • Evaluate laboratory values to determine need for nutrient supplementation specific to CF
  • Discuss age-specific nutrient requirements
  • Recognize nutritional recommendations for CF-related diabetes
  • Discuss the role of education and behavioral intervention in CF nutritional care
  • Understand the rationale for the use of enteral nutrition in CF care

She is also an adjunct researcher and advisor at the Department of Medicine, at Dr. John Shyy’s laboratory at the University of California, San Diego, as well as the founder of Tranquility Community Health. Dr. Marin received a PhD from the University of California, Riverside, in biochemistry and molecular biology; an MPH in epidemiology and biostatistics from Loma Linda University; a bachelor’s degree in emergency medical care from Loma Linda University; and an associate’s degree in respiratory therapy from Victor Valley College.

Lauren Gibson, BSc, RD, is a registered dietitian nutritionist currently practicing at the Tulane University Cystic Fibrosis Center in New Orleans, Louisiana. Originally from Vancouver, Canada, Lauren holds a bachelor of science degree in dietetics from the University of British Columbia. Lauren completed a primarily pediatric dietetic internship, where she first became interested in caring for patients with cystic fibrosis (CF). In her current position, Lauren works as part of an integrated team focused on providing evidence-based care for pediatric CF patients. Lauren is also involved with the Tulane Dietetic Internship Program, where she educates students on the specific needs of CF patients.
