ABSTRACT
BACKGROUND:
patients with chronic peritoneal dialysis (CPD) use glucose-based dialysate to maintain their life; however, whether the glycemic status influences outcome of these patients without diabetes remains unknown.METHODS:
we conducted a cross-sectional and 18-month prospective study, and 269 nondiabetic patients with CPD were enrolled in a medical center. Glycated hemoglobin (HbA1c) levels were measured at baseline and categorized in tertiles of HbA1c high (>5.4%), middle (5.1-5.4%) and low normal (<5.1%). Mortality and cause of death were recorded for longitudinal analyses.RESULTS:
the study results showed high HbA1c group patients had a trend of being older and having higher body mass index (BMI) than other group patients. Stepwise multiple linear regression analysis showed HbA1c was positively related to age, BMI and the peritoneal solute transport rate. After 18 months of follow-up, Cox multivariate analysis showed that HbA1c (HR 4.114; 95% CI 1.426-11.872; p = 0.009) was the significant risk factor for all-cause mortality after relating variables were adjusted. Moreover, high HbA1c (HR 3.892; 95% CI 1.273-11.959; p = 0.026) and low HbA1c (HR 1.179; 95% CI 1.160-1.198; p = 0.039), with middle HbA1c group as the reference, also significantly predicted for mortality in these patients.CONCLUSIONS:
HbA1c levels, or presence of low or high HbA1c, are associated with 18-month all-cause mortality in nondiabetic patients with CPD.
