The influence of glutathione-s-transferase t1/m1 gene polymorphisms on biochemical parameters in children with type 1 diabetes

Background: Glutathione-S-transferase (GST) represents a family of enzymes involved in the metabolism of xenobiotics and also in antioxidant mechanisms. Oxidative stress, as an imbalance between reactive oxygen species origin and antioxidant activity, is discussed in the aetiopathogenesis of type 1 diabetes (T1D) and its chronic complications. Null polymorphisms of GST are associated with significantly lower activity of these enzymes. The aim of the work was to establish the influence of GST T1 and M1 gene polymorphisms on biochemical parameters in children with T1D. Subjects and methods: 116 subjects with T1D at the age 6-19 years were enrolled to the study. Basic anthropometric, biochemical parameters (glycosylated haemoglobin, total cholesterol, LDL, HDL cholesterol, triacylglycerol, creatinine, uric acid, bilirubin, microalbuminury) and null/+ polymorphisms of GST T1 and M1 were investigated in each patient. The results were statistically processed by program SYSTAT. Results: Diabetic patients with GST T1 null allele had significantly higher concentration of total cholesterol (4.75 mmol/l median, 4.10 - 5.43 IQR vs. 4.22 median, 3.61 - 4.72 IQR, p < 0.01), LDL cholesterol (2.81 mmol/l median, 2.02 - 3.60 IQR vs. 2.27 median, 1.73 - 2.80 IQR, p < 0.05) and microalbuminury (5.05 mg/l median, 2.00 - 18.95 IQR vs. 3.20 median, 0.60 - 11.35 IQR, p < 0.05) compared to the patients with GST T1 + allele. No significant difference was found in other biochemical parameters. Diabetic subjects with GST M1 null allele did not significantly differ in any biochemical parameter compared to the subjects with GST M1 + allele. Conclusion: According to our results, GST T1 gene polymorphisms influence the concentration of cholesterol and microalbuminury in children with T1D. Further studies are necessary to clarify detailed associations like the influence on chronic microvascular and macrovascular complications.

PEER-REVIEW PROCESS

Pediatria (Bratislava) is committed to peer-review integrity and ensures the highest standard of review process. After the evaluation of the suitability of the paper for this journal by the Editor, a double-blind peer-review process is initiated. Peer-review process is provided at least by two independent and anonymous expert reviewers according to the standard evaluation criteria. The reviewers are unaware of the identity of the authors, and viceversa, the authors are unaware of the identity of the reviewers. Review manuscripts are treated confidentionally prior their publications. Their recommendations are evaluated by Editors and the final decision (accept as written, accept after minor revision, accept after major revision and elaboration, or reject) is send to the authors. The revision of the paper is expected within two weeks. All the changes should be highlighted in the text (i tis possible to use the tracking tools). The submission of the revised version have to be accompanied by Cover letter with the reactions and responses of the authors point-by-point to the referees‘ reports. All the papers after the acceptance are edited, proof is send to the corresponding author for the final corrections and approval and than all the papers are available on the Journal’s webpage free of charge: http://www.amedi.sk/uvod.html.

PUBLICATION FEES

The papers accepted for publication in Pediatria (Bratisl.) after sucessful peer-review process are published free of charge. The editorial board reserved to make small stylistic changed in the paper.

All the contributions should be sent by e-mail to: stachova@amedi.sk
A confirmation of the manuscript receivement will be send to the corresponding author soonly after the submission.
