Idiopathic pulmonary fibrosis (IPF) is a chronic disease with a growing prevalence. We aimed to evaluate the effects of co-supplementation with vitamins C, E, and D on respiratory, inflammatory, and oxidative stress outcomes in IPF patients.Thirty-three patients participated in this quasi-experimental study and were supplemented with vitamins E, C, and D with 200 IU/daily, 250 mg/every other day and 50000 IU/Weekly, respectively for 12 weeks. Anthropometric indices, dietary recall, physical activity, Saint George questionnaire were assessed along with the biochemical measures of inflammation and oxidative stress, and respiratory parameters. Data were analyzed by SPSS version 21, and P-value ≤ 0.05 was considered significant.Results of spirometry and plethysmography tests showed a significant increase in FEV1 (P-value = 0.016), IRV (P-value = 0.001), RV (P-value = 0.002) and TLC (P-value = 0.003). But no significant change was observed in FVC, VC, FEV1/FVC, and ERV. We also found that ESR, hs-CRP, TGFβ, and PrC remarkably reduced after the supplementation (P-value ≤ 0.05), while the GPx level remained unchanged.It is concluded that three months of supplementation with a combination of D, C, and E vitamins in IPF patients may positively affect the respiratory function and alleviate the inflammation and oxidative stress. |
