摘要
Background and aims: The present study was designed to characterize and compare the ambulatory blood pressure changes of patients with Type 2 diabetic nephropathy (DN) and non-diabetic chronic kidney disease (CKD), and to investigate the features of ambulatory blood pressure in patients with Type 2 diabetic nephropathy (DN) in comparison with those of non-diabetic chronic kidney disease (CKD) in our medical center. Materials and methods: 62 patients with Type 2 diabetic nephropathy (DN) in compliance with the diagnosis criteria of CKD were enrolled in the study, without renal replacement therapy. Their 24-h ambulatory blood pressure monitoring (ABPM) results were observed and compared with the ambulatory blood pressure results of 152 non-diabetic CKD patients with matching age, sex, renal function and other aspects. Results: Analysis of ABPM data from 62 patients with Type 2 DN and 152 patients with nondiabetic CKD indicated: 1. The average 24-h systolic blood pressure (SBP), daytime and nighttime systolic blood pressure (SBP) in the patients with DN were all significantly higher than those of patients with non-DN. 2. Blood pressure variability did not differ considerably between the two groups; nighttime blood pressure decline was small in both groups, but not significantly different. 3. The systolic blood pressure loads in the patients with DN were all significantly higher than those of patients with non-DN. 4. The prevalence of abnormal Circadian BP rhythm was 90.3% in patients with DN, which did not differ considerably from the patients with non-DN represented by 81.6%. 5. The nighttime SBP was correlated with 24-h urinary protein in patients with both non-DN and DN. Conclusions: Systolic blood pressure control of patients with intermediate or advanced diabetic nephropathy was worse than that of patients with non-diabetic CKD, and non-dipping rhythm was quite common. The nighttime SBP correlated with 24-h urinary protein excretion.
