Correlation of serum NGAL and OPG contents with the change of carotid plaques in diabetic patients

Objective:To investigate the correlation of serum NGAL and OPG contents with the change of carotid plaques in diabetic patients.Methods: A total of 99 patients with type 2 diabetes mellitus combined with carotid plaque who were treated in our hospitals between February 2016 and March 2018 were selected as group A and 86 patients with carotid plaque alone were selected as group B. The serum contents of NGAL OPG, inflammatory markers and lipid metabolism indexes were compared between the two groups, and Pearson test was used to evaluate the inner link of serum NGAL and OPG contents with carotid plaque properties in diabetic patients with carotid plaques.Results: Serum NGAL content of group A was higher than that of group B whereas OPG content was lower than that of group B;serum inflammatory markers MMP-9, IL-1β, IL-17 and CRP contents were higher than those of group B;serum lipid metabolism indexes ApoB and Lp-PLA2 contents were higher than those of group B whereas ApoAⅠcontent was lower than that of group B. Correlation analysis showed that serum NGAL and OPG contents of patients with diabetes mellitus combined with carotid plaque were directly correlated with the content of inflammatory markers and lipid metabolism indexes.Conclusion: Serum NGAL content abnormally increases whereas OPG content abnormally decreases in patients with diabetes mellitus combined with carotid plaque, and they are directly correlated with the stability of carotid plaque.
