Introduction and Objective

This study aimed to determine the hepatoprotective effect of caffeine against Ischemia-Reperfusion (IR) damage in Wistar rats.

Material and methods

Eighteen female Wistar rats were divided into three groups (Sham, IR, Caffeine+IR, n=6). Hepatic ischemia was induced at 70% with 1 and 2 hours of reperfusion. The vehicle (saline solution) or 20 mg/kg of caffeine was administered before the induction of IR. The hepatoprotective effect was evaluated with biochemical markers, relative expression of genes associated with oxidative stress and inflammation, proinflammatory cytokines, and histology. The trial was approved by the research ethics committee.

Results

Caffeine significantly reduced levels of ALT, AST and direct bilirubin vs. IR group. Regarding the relative expression of genes, a significant decrease in the expression of the GPX, NF-κβ and IL-1β genes was observed in the group treated with caffeine, while there was a decrease in the concentrations of IL-Iß, IL -6 and TNF-α; however, only TNF- α had a significant decrease. No histological changes were observed in the study groups

Discussion

Caffeine treatment was shown to have a hepatoprotective effect against IR injury, possibly because it is a non-selective antagonist of the adenosine receptor. It has previously been shown that, in the liver, an extracellular increase in adenosine followed by its binding to its A2 receptor, serves to signal an increase in nitric oxide synthesis, which was associated with a cytoprotective effect against IR injury.

Conclusions

Caffeine was shown to have a hepatoprotective effect against IR liver injury

Funding

The resources used in this study were from the hospital without any additional financing

Declaration of interest
