LUNG PROTECTIVE EFFECTS OF CLOPIDOGREL IN POLYMICROBIAL SEPSIS

Aim: The goal of this experiment was to examine if Clopidogrel might protect the lungs during sepsis by modulating the inflammatory and oxidative stress markers.

Materials and Methods: Twenty-four adult male Swiss-albino mice aged 8-12 weeks, with a weighing of 20-30 g, were randomized into 4 equal groups (n=6): sham (Laparotomy without cecal ligation and puncture [CLP]), CLP (laparotomy plus CLP), vehicle (DMSO 1 hour prior to CLP), Clopidogrel (50 mg/g IP 1 hour before to CLP). ELISA was used to assess Lung tissue levels of pro-inflammatory and oxidative stress markers.

Results: F2 isoprostane levels were significantly higher in the sepsis group (p<0.05) in comparison with sham group, while Clopidogrel was considerably lower (p<0.05) in the inflammatory and oxidative stress markers in comparison to sepsis group. Histologically, all mice in the sepsis group had considerable (p=0.05) lung tissue damage, but Clopidogrel considerably decreased lung tissue injury (p=0.05).

Conclusion: Clopidogrel was found to reduce lung tissue cytokine concentrations (IL-1, TNF a, IL-6, F2 isoprostane, GPR 17, MIF) in male mice during CLP-induced polymicrobial sepsis by modulation of pro-inflammatory and oxidative stress cascade signaling pathways, to the best of our abilities, no study has looked at the effect of Clopidogrel on MIF levels.
