Vitamin A may protect lung function in cystic fibrosis (CF) patients. This study found higher vitamin A levels correlated with better respiratory status in individuals with CF.

Area of Science:

  • Pulmonary Medicine
  • Nutritional Science
  • Biochemistry

Background:

  • Cystic Fibrosis (CF) is a genetic disorder affecting lung function.
  • Laboratory studies suggest vitamin A may benefit respiratory health in CF patients.

Purpose of the Study:

  • To investigate the correlation between serum vitamin A concentrations and lung function in stable CF patients.
  • To explore potential associations between vitamins D and E with lung function in this cohort.

Main Methods:

  • Serum concentrations of vitamins A, D, and E were measured.
  • Lung function parameters were assessed in 38 patients with stable CF.
  • Statistical analysis was performed to determine correlations.

Main Results:

  • A significant positive correlation was observed between serum vitamin A levels and all tested lung function parameters.
  • Serum vitamin D and vitamin E concentrations did not show significant correlations with lung function.

Conclusions:

  • Serum vitamin A levels are significantly associated with lung function in patients with cystic fibrosis.
  • Vitamin A may play a protective role in maintaining respiratory status in CF.
  • Further research is warranted to explore vitamin A supplementation in CF management.
