In the current study, possible link between inflammatory status and various related factors in patients with COPD was assessed. Method- Sixty-one COPD patients according to the inclusion criteria participated in this study. For assessing nutritional status, SGA (subjective global assessment) and 24-hour dietary recall method were used and Health-related quality of life (HRQoL) was assessed by St. George’s respiratory questionnaire (SGRQ), instrumental activities of daily living scales (IADLs), and Katz Index. Moreover, Anthropometric and body composition measurements including weight, height, BMI, FFM, and FFMI were measured by standard methods and BIA. Additionally, muscle strength was assessed using a hydraulic hand dynamometer. Finally, blood samples were collected to assess biochemical factors including TNF-α, IL-6, MDA, vitamin C, magnesium, and Glutathione. Stepwise model was performed for evaluating the relationship between inflammatory markers (TNF-α and IL-6) and associated markers mentioned above. Characteristics of participants were expressed in percentage and mean ±SD and analyzed by SPSS software. Results- The results of the current study showed that the intake of PUFA and vegetables, plasma vitamin C and serum MDA could possibly affect inflammation according to IL-6 and TNF- α concentrations. On the other hand, systemic inflammation (IL-6 and TNF-) aggravated mean right and left handgrip strength, Katz index and nutritional status (SGA score) significantly (P <0.05). Conclusion- To sum up, our results confirmed the inter-relationship between inflammatory markers and intake of some dietary components, oxidative stress biomarkers, muscle function, and nutritional status in COPD patients. These factors might affect over each other and further studies are needed to better elucidate this issue.
