Special Issue Information

Dear Colleagues,

Cystic fibrosis (CF) is an inherited disease with significant nutrition-related implications. The past few decades have seen substantial improvements in CF treatment, and consequently in life expectancy. Nutrition therapy has been integral to these improvements.

Historically, CF nutrition has focused on addressing nutritional deficit—a focus which continues. As the survival rate of people with CF has increased, there has been a corresponding increased prevalence of chronic conditions such as obesity, cardiovascular disease, diabetes and cancer, thus expanding the scope of nutrition treatment.

Just as nutrition has been a key factor in enhancing longevity in CF to date, it continues to have an integral role in meeting future challenges in the treatment of the complexities of this disease and its comorbidities.

Based on your insights and expertise in this field, we hope you will consider contributing either evidence-based original research or a critical review for this upcoming Special Issue.

Abstract

Background: The use of oral nutritional supplements (ONS) is common practice in patients suffering from cystic fibrosis (CF). We aimed to describe the rate of ONS use to assess their contribution to dietary intake and to determine if they are associated with respiratory status, body composition, muscle strength, bone mineral density (BMD), bone remodeling biomarkers, and plasmatic levels of vitamins. Methods: Cross-sectional study. Patients were clinically stable adults recruited from the CF unit. A 4-day prospective dietary questionnaire was conducted; in addition to respiratory variables, body composition, and BMD (through densitometry, DXA), muscle strength (JAMAR dynamometer), fat-soluble vitamins, and bone remodeling biomarkers (vitamins A, D, and E; osteocalcin, OC; undercarboxylated osteocalcin, ucOC; degradation of the C-terminal telopeptides of type I collagen, CTX; and receptor activator of nuclear factor-kappaB ligand, RANKL) were also evaluated. Results: The study included 59 subjects with CF (57.6% female, mean age 29.3 ± 9.4 years, and BMI 22.0 ± 3.6 kg/m²). In this study, 22% (13) patients were taking ONS and presented, compared with those not taking them, significantly more total and mild exacerbations and lower BMI; moreover, they showed a significantly higher total daily calorie intake in addition to a higher consumption of carbohydrates, proteins, and lipids per kg of body weight, omega-3 fatty acids, and vitamins A, D, and E. Vitamin E plasmatic levels were significantly higher in the group on ONS, as was the case with RANKL; finally, a lower rate of vitamin D deficiency was also found. Conclusions: ONS were used by patients with worse respiratory and nutritional statuses and their use was associated with a higher intake of macro- and micronutrients and with better plasmatic levels of fat-soluble vitamins.
