Abstract

RATIONALE: Respiratory syncytial virus (RSV) is a major cause of lower respiratory tract infection in children. No treatment has been shown to significantly improve the clinical outcome of patients with this infection. Recent evidence suggests that oxidative stress could play an important role in the pathogenesis of acute and chronic lung inflammatory diseases. We do not known whether RSV induces pulmonary oxidative stress and whether antioxidant treatment can modulate RSV-induced lung disease. OBJECTIVES: To investigate the effect of antioxidant administration on RSV-induced lung inflammation, clinical disease, and airway hyperreactivity (AHR). METHODS: BALB/c mice were infected with 10(7) plaque-forming units of RSV, in the presence or absence of orally administered butylated hydroxyanisole (BHA), an antioxidant. Malondialdehyde and 4-hydroxynonenal were measured in bronchoalveoar lavage (BAL) by colorimetric assay. Cytokines and chemokines were measured in BAL by Bio-Plex and leukotrienes were measured by enzyme-linked immunosorbent assay. AHR to methacholine challenge was measured by whole-body plethysmography. RESULTS: BHA treatment significantly attenuated RSV-induced lung oxidative stress, as indicated by the decrease of malondialdehyde and 4-hydroxynonenal content in BAL of RSV-infected mice. RSV-induced clinical illness and body weight loss were also reduced by BHA treatment, which inhibited neutrophil recruitment to the lung and significantly reduced pulmonary cytokine and chemokine production after RSV infection. Similarly, antioxidant treatment attenuated RSV-induced AHR. CONCLUSION: Modulation of oxidative stress represents a potential novel pharmacologic approach to ameliorate RSV-induced acute lung inflammation and potentially prevent long-term consequences associated with RSV infection, such as bronchial asthma.

  • Vitamin C is an efficient water-soluble antioxidant and its effects on the immune system can be explained by protection against oxidative stress generated during infections.

    “Vitamin C is an efficient water‐soluble antioxidant and the effects on the immune system can be explained by the protection against oxidative stress generated during infections (Akaike 2001; Castro 2006; Hemilä 1992).”

    From Vitamin C for preventing and treating the common cold (2013) · cites this paper as Castro 2006

    The Discussion (page not available) says viral infections can generate oxidative stress and that antioxidants can protect against viral illness and are important in host immune responses. The study tested BHA in RSV-infected mice, not vitamin C; our copy does not establish that vitamin C is water-soluble or that its immune effects arise from this mechanism. (LLM, conf=0.87)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
