Background:
Probiotic ingestion is associated with an increase in intestinal flora of useful bacteria, which contributes to the known protective effects it has on the intestinal barrier and thereby reducing infection. The present study aims to investigate the protective effect of Lactobacillus rhamnosus gg (LGG) as an important probiotic with gastrointestinal barrier strengthening effect in sepsis.
Methods:
Our study was conducted in the Animal Experiments Laboratory after obtaining ethicalapproval to conduct this study.Twenty-four rats were randomly divided into threegroups and group 1 (control group n=8), group 2 (sepsis group, n=8), group 3 (sepsis + probiotic group, n=8) were planned as double-blind. LGG was used as a probiotic. For the sepsis model, E. coli (0111: B4) was injected intraperitoneally, and the rats were sacrificed 48 hours after treatment. Blood samples were collected from all animals before sacrification and sent to the biochemistry laboratory to evaluate oxidant and antioxidant parameters.
Results:
CRP values of Group 1 were significantly lower than Group 2, and CRP values of Group 3 were significantly lower. While total thiol levels of Group 2 were significantly lower than Group 1, total thiol levels of Group 3 were significantly higher than Group 2. There was no statistically significant difference between the groups for eNOS, GPX, PON1 and MDA levels.
Conclusion:
Prophylactic use of probiotics, such as LGG to reduce bacterial translocation and strengthen the immune system, is an inexpensive and effective method of treatment, and we recommend the repetition of studies supported by prospective clinical trials.
