Abstract
BACKGROUND AND AIMS: Neutrophil elastase and myeloperoxidase enzymes protect us from infection by killing pathogens. However, exaggerated activities of these enzymes can induce tissue damage, inflammation and oxidative stress. The present study was aimed to explore the expressions of neutrophil elastase and myeloperoxidase mRNA in the peripheral blood leukocytes (PBL) in patients with newly diagnosed type 2 diabetes mellitus. METHODS: In this cross-sectional study, 104 participants including 65 normoglycemic control subjects and 39 newly diagnosed type 2 diabetes patients were recruited. Glycemic and metabolic markers were evaluated from fasting blood samples. The mRNA levels of neutrophil elastase and myeloperoxidase genes in the PBL were quantified by real-time quantitative PCR. RESULTS: Compared to control subjects, diabetes patients showed a significant down regulation of both neutrophil elastase (p = 0.039) and myeloperoxidase (p = 0.023) mRNA expressions in the PBL. The neutrophil elastase and myeloperoxidase mRNA levels showed a negative trend with fasting glucose levels but did not show any significant correlations with HbA1c, insulin level, insulin resistance or sensitivity status. CONCLUSIONS: It was concluded that type 2 diabetes mellitus is associated with a decrease in neutrophil elastase and myeloperoxidase gene expression in the PBL.
