Abstract:Objective To investigate the association of plasma glutaredoxin (Grx) with carotid atherosclerosis (CAS) in newly-diagnosed type 2 diabetic patients. Methods A total of 100 patients who were newly diagnosed as T2DM and cared in the Department of Endocrinology of Tangshan People's Hospital from January 2016 to May 2016 were recruited, and divided into CAS group (52 cases) and non-CAS group (NCAS group, 48 cases). At the same time, 55 healthy subjects without T2DM from the Medical Examination Center were recruited as normal control (NC) group. Data including age, sex, BMI, SBP and DBP were recorded. Clinical parameters including FPG, HbA1c, TC, TG, LDL-C, HDL-C, Hcy and hs-CRP were collected. Plasma Grx level was measured by enzyme-linked immunosorbent assay (ELISA). Results The levels of Grx of the CAS and NCAS groups were both higher than that of the NC group, and the levels of Grx of the CAS group was higher than that of the NCAS group (all P < 0.05). In the T2DM patients, Grx was positively correlated with HbA1c and hs-CRP (P < 0.05). Logistic regression analysis showed that age (■ = 1.225, P = 0.021), HbA1c (■ = 1.754, P = 0.016) and Grx (■ = 1.556, P = 0.009) were the risk factors of CAS in the T2DM patients. Conclusions Plasma Grx is closely correlated with carotid atherosclerosis in newly-diagnosed type 2 diabetic patients, suggesting that plasma Grx may be involved in the occurrence and development of carotid atherosclerosis in newly-diagnosed T2DM patients.
