Abstract:
Objective More and more research shows microangiopathy may occur in the early stage of diabetes. The purpose of this study was to observe the relationship between OGTT 1-hour hyperglycemia (1hPG) and 2-hour hyperglycemia (2hPG) levels and urinary albumin creatinine ratio (UACR).Methods We retrospectively analyzed 408 patients with primary hypertension of grade 2 or above who were eligible for 2015 World Health Organization (WHO) outpatient and inpatient visits from September 2015 to April 2018 in our hospital for a course of up to 10 years. All selected participants underwent an OGTT test (1 and 2 hour post-sugar glucose) and records were made on fasting plasma glucose (FPG), OGTT1-hour blood glucose (1 hPG), OGTT 2-hour blood glucose (2 hPG). All the patients were divided into 4 groups according to blood glucose levels: NGT group (n=100), 1 h PG group(n=102), 2h PG group(n=104), 1h PG/2h PG group (n=102). Records were made on the clinical data of 408 patients, including height, weight, BMI, gender, age, history of hypertension, smoking history, blood pressure, blood lipids, creatinine and other general clinical data, and the calculation of glomerular filtration rate (eGFR) values was based on creatinine values and age values to analyze the relationship between 1 hHPG and 2 hHPG levels with ACR.Results No significant difference was found among the four groups in the aspects of hypertension course, age, gender, body mass index (BMI), diastolic blood pressure, lipid metabolism index and fasting blood glucose(P>0.05). There were significant difference in systolic blood pressure, serumcreatinine, eGFR, and ACR among different levels of increased blood glucose(P<0.05). ACR in 1h PG group, 2h PG group and 1h PG/2h PG group were significantly higher than NGT group(P<0.01), ACR in 1h HPG/2hHPG was significantly higher than 1h PG group(P<0.05) and ACR in 1h PG group was significantly higher than 2h HPG group(P<0.05). The logistic regression analysis showed that 1h PG(OR=2.461, 95%CI:1.947-3.112), creatinine (OR=1.071, 95%CI:1.027-1.117) and 2h PG(OR=2.016, 95%CI:1.500-2.710) were risk factors for microalbuminuria(P<0.01).Conclusion The abnormalities of 1h PG and 2h PG are associated with ACR, which may become the key index for predicting early kidney damage.
