Vitamins C and E protect from sepsis-induced lung damage in rat and CT correlation
Özet
BACKGROUND: Sepsis is one of the leading causes of death in intensive care units worldwide. Vitamins C and E are natural antioxidants and anti-infl ammatory agents. Suppressing the infl ammation is an important treatment target because it plays a role in the pathophysiology of sepsis. The purpose of this study was to investigate the effect of vitamins C and E treatment in rats with sepsis-induced lung damage. METHODS: In this animal study, fecal intraperitoneal injection procedure (FIP) was performed on 30 of 40 rats included for creating a sepsis model. Rats were randomly assigned into four groups: Group 1, control group (no procedure was applied, n = 10), Group 2, FIP (untreated septic group n = 10), Group 3, FIP+vitC (treated with 500 mg/kg/day ascorbic acid, n = 10), and Group 4, FIP+vitE (treated with 300 mg/kg/day alphatocopherol, n = 10). Chest CT was performed in all rats and density of the lungs was measured by using Hounsfi eld unit (HU). Histopathological examination of lung damage was performed, and blood samples were collected for biochemical analysis. RESULTS: TNF-?, CRP, IL 1-?, IL-6, and MDA plasma levels in groups treated with vitamin C or vitamin E were lower than in the FIP group. Histological scores in groups treated either with vitamin C or vitamin E were signifi cantly lower as compared to those in the FIP group. The HU value of lung in groups treated wither with vitamin C or vitamin E were lower than that in the FIP group (p < 0.05). CONCLUSION: The rats treated either with vitamin C or E showed improved results for sepsis. We think that they can be used as adjuvant therapy for septic patients because of their effectivity and low costs. © 2022, Bratislava Medical Journal. All Rights Reserved.
