Abstract EN
Oxidative stress is an important part of host innate immune response to foreign pathogens.
However, the impact of vitamin C on oxidative stress and inflammation remains unclear in community-acquired pneumonia (CAP).
We aimed to determine the effect of vitamin C on oxidative stress and inflammation.
CAP patients were enrolled.
Reactive oxygen species (ROS), DNA damage, superoxide dismutases (SOD) activity, tumor necrosis factor-alpha (TNF-α), and IL-6 were analyzed in CAP patients and LPS-stimulated macrophages cells.
MH-S cells were transfected with RFP-LC3 plasmids.
Autophagy was measured in LPS-stimulated macrophages cells.
Severe CAP patients showed significantly increased ROS, DNA damage, TNF-α, and IL-6.
SOD was significantly decreased in severe CAP.
Vitamin C significantly decreased ROS, DNA damage, TNF-α, and IL-6.
Vitamin C inhibited LPS-induced ROS, DNA damage, TNF-α, IL-6, and p38 in macrophages cells.
Vitamin C inhibited autophagy in LPS-induced macrophages cells.
These findings indicated that severe CAP exhibited significantly increased oxidative stress, DNA damage, and proinflammatory mediator.
Vitamin C mitigated oxidative stress and proinflammatory mediator suggesting a possible mechanism for vitamin C in severe CAP.
