摘要
目的研究2型糖尿病患者肾功能减退对血浆脑钠肽(BNP)质量浓度的影响。方法2005年2—7月,对重庆医科大学附属第一医院77例2型糖尿病患者血浆BNP质量浓度及BNP的可疑影响因素(包括年龄、性别、血压、体重指数、糖化血红蛋白、血脂、肾功能等)进行测定。结果肾功能正常组[内生肌酐清除率(Ccr)≥1.5mL/s]、肾功能轻度减退组(1.0mL/s≤Ccr〈1.5mL/s)和肾功能重度减退组(Ccr〈1.0mL/s)患者血浆BNP质量浓度差异有显著性意义[(6.7±8.5)ng/L,(13.2±13.1)ng/L,(62.7±71.6)ng/L,P〈0.05];大量蛋白尿组[尿白蛋白排除率(UAER)≥300mg/d]、微量蛋白尿组(30mg/d≤UAER〈300mg/d)和极微量蛋白尿组(UAER〈30mg/d)患者血浆BNP质量浓度差异也具有显著性意义[(110.6±87.1)ng/L,(15.3±14.2)ng/L,(10.8±14.0)ng/L,P〈0.05]。结论肾功能下降可引起2型糖尿病患者血浆BNP质量浓度升高。
Objective To study effects of diabetic nephropathy on plasma brain natriuretic peptide levels in type 2 diabetic patients. Methods Serum BNP levels and suspected influential factors (including age, sex, blood pressure, body mass index, HbA1c,blood lipid, renal function) were investigated in 77 patients with type 2 diabetes mellitus. Results Serum BNP was significantly different [ (6. 7 ± 8. 5 ) ng/L, ( 13. 2± 13. 1 ) ng/L, (62. 7 ± 71.6) ng/L, P 〈 0. 05 ] among renal normal-function group( Ccr≤ 1.5 mL/s)and renal mildly abnormal-function group( 1.0 mL/s ≤ Ccr 〈 1.5 mL/s)and renal markedly abnormal-function group ( Ccr 〈 1.0 mL/s) ; serum BNP was also different [ ( 110. 6 ± 87. 1 ) ng/L, ( 15.3 ± lg. 2 ) ng/L, ( 10. 8 ± 14. 0) ng/L, P 〈 0. 05 ] among macroalbuminuric group( UAER ≥300 mg/d) and microalbuminuric group(30mg/d≤UAER 〈300 mg/d)and normalbuminuric group(UAER 〈30 mg/d). Conclusion Renal dysfunction can raise serum BNP levels in type 2 diabetic patients.
