摘要 目的评估2型糖尿病(T2DM)患者血清丙氨酸氨基转移酶(ALT)水平与心血管疾病风险的关系。方法选取临床资料齐全的T2DM患者676例,所有患者均排除慢性病毒性肝炎,自身免疫性、药物、酒精及其他遗传性所致的肝病。676例患者按ALT水平分为ALT升高组(ALT〉40U/L,126例)和ALT正常组(ALT5—40U/L,550例);ALT正常组患者再按照ALT水平四分位分组(1、2、3、4组),1组108例(ALT5—11U/L),2组114例(ALT12~15U/L),3组127例(ALT16~21U/L),4组201例(ALT22~40U/L),比较各组的年龄、糖尿病病程、体质指数(BMI)、腰臀比(wHR)、血压、三酰甘油(TG)、总胆固醇(TC)、高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LOL—C)、空腹血糖(FPG)、餐后2h血糖(2hPG)、糖化血红蛋白(HbA1c)、尿酸(UA)、空腹胰岛素、稳态模型评估法胰岛素抵抗指数(HOMA.IR)等的差异。结果ALT升高组BMI、WHR、舒张压、FPG、2hPG、HbA1c、空腹胰岛素、TG、HOMA—IR、UA均较ALT正常组明显升高[(26.80±3.60)kg/m^2比(23.40±3.50)kg/m^2、0.95±0.05比0.91±0.05、(75.3±9.3)mmHg(1mmHg=0.133kPa)比(69.2±9.5)mmHg、(9.24±2.56)mmol/L比(8.53±2.78)mmol/L、(15.25±4.62)mmol/L比(14.37±5.06)mmol/L、(8.31±1.76)%比(7.78±1.94)%、(10.76±6.78)mU/L比(7.85±7.04)mU/L、(2.73±2.40)mmol/L比(2.20±2.78)mmol/L、4.13±2.76比3.06±2.63、(332.42±95.12)μmol/L比(285.14±79.53)μmol/L](P〈0.05),HDL-C则明显降低[(1.06±0.27)mm01]L比(1.15±0.57)mmol/L](P〈O.05);相对于ALT正常组,ALT升高组年龄更轻,糖尿病病程更短[(49.6±10.5)岁比(57.5±11.3)岁,(37.9±42.0)个月比(54.5±57.8)个月](P〈0.05)。ALT正常组按照ALT水平四分位分组后,4组患者与1、2、3组比较,FPG、2hPG、HbA1c、UA均明显升高[(9.18±3.01)mmol/L比(8.33±2.57)、(8.38±2.52)、(8.45±2.73)mmol/L;(14.56±4.80)mmol/L比(13.15±5.72)、(13.42±4.56)、(13.50±5.17)mmol/L;(7.81±1.98)%比(6.76±1.84)%、(6.79±2.10)%、(6.88±2.43)%;(288.24±78.26)μmol/L比(271.15±75.43)、(273.27±71.25)、(275.56±69.57)μmol/L](P〈0.05);HOMA.IR明显下降(2.67±2.65比2.84±2.53、2.98±3.10、3.12±2.57,P〈0.05)。结论随着ALT水平的升高,T2DM患者有着更严重的胰岛素抵抗和更多的心血管危险因素。 Objective To study the association of the serum alanine aminotransferase (ALT) level with cardiovascular risks in patients with type 2 diabetes mellitus (T2DM). Methods A total of 676 patients with T2DM who excluded liver disease due to chronic viral hepatitis, autoimmune, drugs, alcohol, and other hereditary were selected. According to the ALT level, 676 patients were assigned into elevated ALT group (ALT 〉 40 U/L, 126 cases) and normal ALT group (ALT 5-40 U/L,550 cases). And normal ALT group were divided into 4 groups on the interquartile distance: group 1 (ALT 5-11 U/L, 108 cases), group 2 (ALT 12- 15 U/L, 114 cases), group 3 (ALT 16-21 U/L, 127 cases), group 4 (ALT 22-40 U/L, 201 cases). The age, duration of diabetes, body mass index (BMI),waist-to-hip ratio (WHR), blood pressure, triglyceride (TG),total cholesterol (TC), high density lipoprotein cholesferol (HDL-C), low density lipoprotein cholesferol (LDL-C), fasting plasma glucose (FPG),2 h postprandial blood glucose (2 hPG), glycosylated hemoglobin (HbA1c), uric acid (UA), fasting insulin and homeostasis model assessment insulin resistance index (HOMA-IR) was compared among these groups. Results The levels of BMI, WHR, diastolic blood pressure, FPG, 2 hPG, HbA1c, fasting insulin, TG, HOMA-IR and UA in elevated ALT group were higher than those in normal ALT group [ (26.80 ± 3.60 ) kg/m^2 vs. (23.40 ± 3.50 ) kg/m^2, 0.95 ± 0.05 vs. 0.91 ± 0.05, (75.3 ± 9.3 ) mm Hg ( 1 mm Hg = 0.133 kPa) vs. (69.2 ± 9.5 ) mm Hg, (9.24 ± 2.56) mmol/L vs. (8.53 ± 2.78 ) mmol/L, ( 15.25 ± 4.62 ) mmol/L vs. ( 14.37 ± 5.06) mmol/L, ( 8.31 ± 1.76 )% vs. (7.78 ± 1.94)%, (10.76 ±6.78) mU/L vs. (7.85 ±7.04) mU/L, (2.73 ±2.40) mmol/L vs.(2.20 ±2.78) mmol/L, 4.13 ± 2.76 vs. 3.06 ± 2.63, (332.42 ± 95.12) μmol/L vs. (285.14 ± 79.53 ) μ mol/L ] (P 〈 0.05 ), and HDL-C was lower than that in normal ALT group [ ( 1.06 ± 0.27 ) mmol/L vs. ( 1.15 ± 0.57 ) mmol/L ] (P 〈 0.05). Compared with that in normal ALT group, the age was younger, and the duration of diabetes was shorter in elevated ALT group [(49.6 ± 10.5) years vs. (57.5 ± 11.3) years, (37.9 ±42.0) months vs. (54.5 ± 57.8) months ] (P 〈 0.05). The levels of FPG, 2 hPG, HbAlc and UA in group 4 were higher than those in group 1,2,3 [ (9.18 ± 3.01) mmol/L vs.(8.33 ± 2.57), (8.38 ± 2.52), (8.45 ± 2.73) mmol/L; (14.56 ± 4.80) mmol/L vs.(13.15 ± 5.72), (13.42 ± 4.56), (13.50 ± 5.17) mmol/L; (7.81 ± 1.98)% vs. (6.76 ± 1.84)%, (6.79 ± 2.10)%, (6.88 ± 2.43)% ; (288.24 ± 78.26) μmol/L vs. (271.15 ± 75.43), (273.27 ± 71.25 ), (275.56 ± 69.57) μmol/L ] (P 〈 0.05) ;HOMA-IR was lower than that in group 1,2,3 (2.67 ± 2.65 vs. 2.84±2.53,2.98±3.10,3.12±2.57,P〈0.05). Conclusion The increase of ALT level is associated with the clustered cardiovascular risk factors and insulin resistance in patients with T2DM.
