ABSTRACT
Objective To investigate the correlation between glycosylated hemoglobin (HbAlc) and carotid intima-media thickness (CIMT) in non-diabetic peritoneal dialysis patients.Methods Forty-two non-diabetic peritoneal dialysis adult patients were enrolled in this study [mean age was (48.2± 12.3) years,50％ was male].CIMT was determined by carotid ultrasound.Patients were divided into two groups according to CIMT:CIMT normal group (CIMT ＜ 0.9 mm) and CIMT thickening group (CIMT≥0.9 mm).HbAlc,2-hour postprandial blood glucose (2hPBG) and other factors of the patients were analyzed with Spearman rank correlation and multiple linear regression.Results CIMT was correlated with age,2hPBG,LDL-C,TG,TC,HbA1c in non-diabetic peritoneal dialysis patients (r =0.355,0.373,0.416,0.345,0.351,0.456,all P ＜ 0.05).Multiple linear regression showed that HbA1c was the most powerful influence factor of CIMT(β =0.459).Conclusion HbA1c level is positively correlated with CIMT and may be a predictor of carotid atherosclerosis in non-diabetic peritoneal dialysis patients.
