Insights
Early nutritional intervention significantly improves weight and anthropometrics in pediatric cystic fibrosis (CF) patients. Good nutritional status is closely linked to better pulmonary function in CF.
Area of Science:
- Pediatric Pulmonology
- Nutritional Science
- Genetic Diseases
Context:
- Cystic Fibrosis (CF) is a genetic disorder affecting multiple organs, particularly the lungs and digestive system.
- Pediatric patients with CF often face challenges in maintaining adequate nutritional status due to malabsorption and increased metabolic demands.
- Early and continuous nutritional support is crucial for managing CF and its complications.
Purpose:
- To evaluate the impact of early and consistent nutritional intervention on the nutritional status and pulmonary function of pediatric patients with cystic fibrosis (CF).
- To explore the correlation between nutritional status and respiratory outcomes in young CF patients.
- To determine the necessity and effectiveness of various nutritional support strategies in CF management.
Summary:
- This study followed 19 pediatric CF patients (17 months to 18 years) over a mean of 10 years, assessing nutritional status (NS) and pulmonary function via regular clinical, anthropometrical, and spirometry evaluations.
- Nutritional interventions included dietary recommendations, oral/invasive enteral nutrition (EN), and supplementation. Anthropometrical improvements, particularly in weight and skinfold thickness, were significant (p < 0.05).
- Despite high rates of exocrine pancreatic failure (84%) and Pseudomonas aeruginosa colonization (73%), patients showed improved weight and a strong correlation between nutritional status (weight/height ratio) and pulmonary function (FVC, FEV1).
Impact:
- Early and continuous nutritional intervention, including enteral nutrition (EN), is vital for improving anthropometric measures in pediatric CF patients.
- Maintaining optimal nutritional status is directly correlated with better pulmonary function (FVC and FEV1) in children with CF.
- Effective nutritional monitoring and support are essential for meeting the demands of CF and improving overall patient outcomes.
Objective:
To assess the effects of early and continuous nutritional intervention in pediatric patients with cystic fibrosis (CF) and its possible implication in pulmonary function.
Patients And Methods:
Included is the follow-up of 19 patients with CF (11 female and 8 male children), from 17 months to 18 years of age, and a mean disease duration of 10 years. Genotype from 16 patients is delta F 508 (10 homozygotic, 6 heterozygotic). The following items have been performed every 2-3 months: clinical, dietary and anthropometrical assessment, classifying nutritional status (NS) by Z scores of weight/height, % of weight to height, body mass index, and Z scores of height/age. Concurrently, respiratory secretions culture and spirometry were obtained; and annually, biochemistry, hematologic and feces determinations. Nutritional intervention included: dietary recommendations, oral or invasive enteral nutrition (EN) and pharmacologic treatment with pancreatic enzymes, fat-soluble vitamins, minerals and oligoelements. RESULTS AND COMMENTARIES: Most of them experienced anthropometrical improvement being significant for weight, the relationship of weight/height and the tricipital fold (p < 0.05). The Z score for height has remained steady. Sixteen patients (84%) have developed exocrine pancreatic failure, and 3 (16%) glucose intolerance. Fourteen (73%) have been colonized by Pseudomonas aeruginosa. Last mean spirometry values were: FVC (%) 85.4 +/- 18.6 and FEV1 (%) 85.9 +/- 24.1, with a significant correlation between % of weight to height and FVC (coefficient 0.552, p = 0.022) and FEV1 (coefficient 0.625, p = 0.007). Seventy nine percent have required some sort of nutritional support: 3 cases (16%) invasive EN, and the remaining oral EN.
Conclusions:
Without nutritional support, many patients with CF do not seem to meet their demands. EN monitoring allows for and early and effective intervention. A close correlation has been demonstrated between nutritional status and pulmonary function.

Pulmonary Function Tests
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
