BACKGROUND: Previous study had reported the imbalance of pro- and anti-oxidants in tuberculosis (TB), which was involved in the TB progression. This study aimed to identify the key oxidative stress indicator associated with oxidative balance in patients with TB infection.
METHODS: Overall, 339 participants with TB were included in this study. The oxidative balance score (OBS) was composed of scores of dietary and lifestyle factors. Trend regression analysis, generalized additive model, polynomial regression, and threshold effect analysis, were used to examine the relationship between the serum 25-hydroxyvitamin D3 25(OH)D3 and OBS. Moreover, the correlation between serum 25(OH)D3 and OBS components was explored via Pearson analysis, and mediation analysis was used to explore the function of OBS components.
RESULTS: Linear regression analysis showed that among 6 oxidative stress indicators, only serum 25(OH)D3 was independently related to the OBS. A positive association between them was then found (P for trend<0.05) in a non-linear relationship (all P<0.05). The 25(OH)D3 concentration of 51.9nmol/L was identified as the key turning point by threshold effect analysis, and their association was only found when it <51.9nmol/L. Further, we revealed that 25(OH)D3 mainly correlated with 2 OBS components including BMI and riboflavin. Moreover, BMI and riboflavin were found to mediate the association of serum 25(OH)D3 with OBS by mediation analysis (all P<0.05).
CONCLUSIONS: In summary, our study revealed relationship between the serum 25(OH)D3 and OBS in patients with TB, which provided a piece of evidence that vitamin D can assist the treatment of TB.
