Correlation between glycosylated hemoglobin and carotid intima-media thickness in non-diabetic peritoneal dialysis patients

Objective To investigate the correlation between glycosylated hemoglobin (HbA1c) 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). HbA1c, 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.
