目的

探讨硫辛酸对不同时期糖尿病肾病患者尿微量白蛋白和炎症的影响。

方法

选取2015年7月至2017年12月在梅州市人民医院内分泌科住院治疗的2型糖尿病患者90例,根据24 h尿微量白蛋白排泄率(UAER)分为3组,即正常白蛋白尿组(NA,UAER<30 mg/24 h)、微量白蛋白尿组(MA,30 mg/24 h≤UAER<300 mg/24 h)和临床肾病组(CN,UAER≥300 mg/24 h);同时随机选取同期健康体检者30名作为正常对照组(NC)。再将3组糖尿病患者按随机数字表法随机分为等样本量的观察组和对照组,对照组给予常规治疗,观察组在常规治疗基础上给予注射用硫辛酸0.45 g加入0.9 %氯化钠注射液250 ml中避光缓慢静滴,1次/d,共2周。观察各组患者UAER、血清肌酐(SCr)、血糖、血清超敏C反应蛋白(hs-CRP)、血清肿瘤坏死因子α(TNF-α)水平的变化。

结果

2型糖尿病肾病患者血清hs-CRP、TNF-α水平明显高于正常对照组[(5.98±1.54)mg/L vs (6.49±1.84)mg/L vs(7.02±1.75)mg/L vs(2.95±0.86)mg/L;(17.19±5.05)ng/L vs(19.61±5.42)ng/L vs (20.25±6.23)ng/L vs (10.24±3.16)ng/L],差异具有统计学意义(F=15.63、25.22,P均<0.01),但糖尿病肾病不同时期比较差异无统计学意义;观察组经硫辛酸治疗后与对照组治疗后比较,其hs-CRP、TNF-α、SCr、UAER水平明显降低[(5.01±0.93)mg/L vs (3.89±0.72)mg/L,(5.51±1.23)mg/L vs (4.25±0.88)mg/L,(6.15±1.32)mg/L vs (4.78±1.01)mg/L;(15.59±4.19)ng/L vs (12.04±3.45)ng/L,(18.02±4.42)ng/L vs (14.43±4.22)ng/L,(18.67±4.88)ng/L vs (15.09±4.47)ng/L;(83.5±9.4)μmol/L vs (67.3±6.2)μmol/L,(85.6±16.0)μmol/L vs (61.3±16.7)μmol/L,(98.5±20.4)μmol/L vs (69.4±16.8)μmol/L;(16.5±7.4)mg/24 h vs(13.3±6.2)mg/24 h,(145.6±66.0)mg/24 h vs (106.3±56.7)mg/24 h,(805.5±166.4)mg/24 h vs(612.3±110.8)mg/24 h],差异具有统计学意义(t=3.689、3.227、3.192、2.526、2.275、2.095、5.572、4.069、4.265、5.597、2.051、3.742,P均<0.05)。

结论

2型糖尿病肾病患者存在炎症反应,硫辛酸可改善2型糖尿病肾病炎症状态,减少尿微量白蛋白排泄和降低血肌酐水平,从而达到肾保护作用。

Objective

To investigate the effect of lipoic acid on urinary microalbumin and inflammation in patients with diabetic nephropathy at different stages.

Methods

Ninety patients with type 2 diabetes who were hospitalized at the Department of Endocrinology, Meizhou People's Hospital from July 2015 to December 2017 were selected, and they were divided into three groups according to 24-hour urinary albumin excretion rate (UAER): normal albuminuria group (NA group, UAER<30 mg/24 h), microalbuminuria group (MA group, 30 mg/24 h≤UAER<300 mg/24 h), and clinical nephropathy group (CN group, UAER≥300 mg/24 h). At the same time, we randomly selected 30 patients who underwent physical examination as a normal control group (NC group). Then, the three groups of diabetes patients were randomly and equally divided into an observation group and a control group using a random number table. The control group was given conventional treatment. The observation group was given 0.45 g lipoic acid for injection plus 0.9% sodium chloride injection 250 mL by slow intravenous infusion, once a day for 2 weeks. The changes of UAER, serum creatinine (SCr), blood glucose, hs-CRP, and TNF-α levels were observed.

Results

The levels of serum hs-CRP and TNF-α in the three groups of patients with type 2 diabetic nephropathy were significantly higher than those in the NC group [(5.98±1.54) mg/L, (6.49±1.84) mg/L, (7.02±1.75) mg/L vs (2.95±0.86) mg/L, F=15.63, P<0.01; (17.19±5.05) ng/L, (19.61±5.42) ng/L, (20.25±6.23) ng/L vs (10.24±3.16) ng/L, F=25.22, P<0.01]; however, there was no significant difference among the three groups of patients with type 2 diabetic nephropathy. The levels of hs-CRP, TNF-α, SCr, and UAER were decreased significantly after lipoic acid treatment in the observation groups than in the control groups [(5.01±0.93) mg/L vs (3.89±0.72) mg/L, (5.51±1.23) mg/L vs (4.25±0.88) mg/L, (6.15±1.32) mg/L vs (4.78±1.01) mg/L, t=3.689, 3.227, 3.192, P<0.05; (15.59±4.19) ng/L vs (12.04±3.45) ng/L, (18.02±4.42) ng/L vs (14.43±4.22) ng/L, (18.67±4.88) ng/L vs (15.09±4.47) ng/L, t=2.526, 2.275, 2.095, P<0.05; (83.5±9.4) μmol/L vs (67.3±6.2) μmol/L, (85.6±16.0) μmol/L vs (61.3±16.7) μmol/L, (98.5±20.4) μmol/L vs (69.4±16.8) μmol/L, t=5.572, 4.069, 4.265, P<0.05; (16.5±7.4) mg/24 h vs (13.3±6.2) mg/24 h, (145.6±66.0) mg/24 h vs (106.3±56.7) mg/24 h, (805.5±166.4) mg/24 h vs (612.3±110.8) mg/24 h, t=5.597, 2.051, 3.742, P<0.05].

Conclusion

The inflammatory reaction exists in type 2 diabetic nephropathy patients. Lipoic acid can protect the kidney by improving the inflammatory state of type 2 diabetic nephropathy, reducing urinary microalbumin excretion, and lowering serum creatinine levels.
