Background and objective: Type 1 diabetes mellitus (T1D) is found worldwide and is regarded as one of the main risks to human health. The objective of this study was to determine the state of lipid peroxidation (LPO) and antioxidant protection in girls with T1D type considering the stages of reproductive system development.
Materials and methods: This study enrolled 56 young girls with T1D and 60 healthy girls (control) matched by age. The study population was divided into 3 age groups: prepubertal, adolescent, and juvenile. The state of LPO and antioxidant system was assessed using the coefficient of oxidative stress that represented the ratio of LPO products to general antioxidative blood activity. Spectrophotometric and fluorometric methods were applied.
Results: The results of our study showed increased conjugated diene (CD) and thiobarbituric acid reactant (TBAR) concentrations as well as a decreased reduced glutathione level in prepubertal girls with T1D. Adolescent girls with T1D had a significantly greater CD level and juvenile girls with T1D had a significantly greater TBAR level and lower α-tocopherol concentration than girls in the control group. The greatest coefficient of oxidative stress (1.16) was observed in the prepubertal period.
Conclusions: The prepubertal period is characterized by the most severe state of lipid peroxidation process–antioxidant protection.
