Abstract:

Objective To explore the relationship between urinary albumin in patients with type 2 diabetes and the increase in blood glucose (2hPG-FBG) 2 hours after oral 75 g glucose tolerance test (OGTT) glucose load. Methods The electronic medical record system, 120 patients with type 2 diabetes who were hospitalized in the Endocrinology Department of the Second Hospital of Hebei Medical University were retrospectively collected. According to the urine albumin/creatinine ratio (UACR), the patients were divided into normal urine albumin group (group N: UACR<30 mg/g), microalbuminuria group (group A: 30 mg/g≤UACR<300 mg/g) and massive albuminuria group (group B: UACR≥300 mg/g). The differences in the indicators among three groups were compared. Results 2 hPG-FBG in microalbuminuria group was higher than that of normal urine albumin group, and massive albuminuria group was higher than that of the microalbuminuria group (P<0.05). The HbA1c in microalbuminuria group and massive albuminuria group were higher than that of normal urine albumin group (P<0.05). Spearman correlation analysis showed that UACR was positively correlated with HbA1c (r=0.294) and 2 hPG-FBG (r=0.516) (all P<0.05). Multiple linear stepwise regression analysis showed that 2 hPG-FBG was an independent risk factor for UACR (β=3.239). Conclusion Postprandial blood glucose fluctuation, represented by 2 h blood glucose increase after glucose loading, is an important factor causing the increase of urinary albumin in patients with type 2 diabetes, and its effect is more obvious than that of sustained blood glucose level.
