RESUMO
OBJECTIVE: To analyze the related factors regarding diabetic nephropathy (DN). METHODS: A total number of 756 diabetic patients from 2009 to 2011 were analyzed retrospectively. Three groups were formed according to the urinary albumin excretion rates (UAER). Patients with UAER < 20 µg/min was grouped to group A, with UAER from 20 to 200 µg/min as group B, and the others with UAER ≥ 200 µg/min was grouped to group C. General characteristics and laboratory parameters were then compared and related factors of DN analyzed. RESULTS: The constituent ratio of nephropathy was 30.2% (228/756). Patient's age, duration of disease, both diastolic and systolic blood pressure of group A were significantly higher than the non-DN group (A) (P < 0.05). Patient's age, disease duration, both diastolic and systolic blood pressure of group C were (64.08 ± 11.71) years, (14.67 ± 7.34) years, (87.43 ± 14.36) mm Hg, (152.45 ± 18.48) mm Hg, respectively, with statistically significant difference (P < 0.05) between group C and group B. FPG, TG, TC, HDL-C, UA, HbA1c, FINS, FCP of group B were (9.27 ± 3.06) mmol/L, (1.98 ± 0.37) mmol/L, (5.01 ± 1.08) mmol/L, (1.05 ± 0.35) mmol/L, (312.78 ± 39.83) mmol/L, (9.33 ± 1.47)%, (11.45 ± 7.83) µU/ml, (509.73 ± 132.78) pmol/L respectively, with significant difference (P < 0.05) between group B and group A. FPG, TG, HDL-C, UA, FINS, FCP of group C were (9.29 ± 3.12) mmol/L, (2.02 ± 0.36) mmol/L, (1.04 ± 0.27) mmol/L, (389.72 ± 46.32) mmol/L, (11.09 ± 8.29) µU/ml, (575.77 ± 143.29) pmol/L respectively, with significant difference (P < 0.05) between group C and group A. UA, FINS, FCP were found with significant differences (P < 0.05) between group C and group B. Data from multivariate logistic regression showed that DNs were related with disease duration, BMI, systolic blood pressure, HbAlc, FPG, UA. CONCLUSION: DN was closely related to the duration, age, blood sugar, blood lipids, blood pressure, uric acid levels of the disease.
