摘要:

目的: 探讨载脂蛋白E (apolipoprotein E,ApoE)基因多态性及血脂水平与肺结核患病的相关性。方法: 采用回顾性研究方法,选取2016年1月1日至2020年12月12日梅州市人民医院诊断为肺结核的1118例患者作为病例组,选取同期于本院体检健康者582名作为对照组。收集研究对象的基本信息(年龄,性别)及实验室检验指标[包括血常规,甘油三酯(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(LDL-C),载脂蛋白A1(Apo-A1),载脂蛋白B(Apo-B),ApoE基因分型检测结果]。分析病例组与对照组ApoE基因型分布情况、血脂水平差异、ApoE基因型与血脂水平的相关性,并采用多因素logistic回归分析ApoE基因型及血脂水平对肺结核患病的影响。结果: 病例组的TG、TC、HDL-C、LDL-C、Apo-A1、Apo-B水平分别为:1.23(0.76,1.47)mmol/L、(4.18±1.17)mmol/L、(1.14±0.38)mmol/L、(2.36±0.82)mmol/L、(0.94±0.32)g/L、(0.79±0.26)g/L,均明显低于对照组[分别为1.64(1.07,2.06)mmol/L、(5.24±1.18)mmol/L、(1.36±0.34)mmol/L、(2.98±0.90)mmol/L、(1.31±0.33)g/L、(0.97±0.29)g/L],差异均有统计学意义(U=-12.603、t=17.605、t=12.096、t=13.784、t=22.614、t=12.071,P值均<0.001)。病例组中携带ApoE基因ε2/ε3基因型者的TG、TC、HDL-C、LDL-C、Apo-A1、Apo-B水平分别为1.21(0.73,1.38)mmol/L、(3.81±1.21)mmol/L、(1.17±0.36)mmol/L、(2.01±0.79)mmol/L、(0.96±0.32)g/L、(0.67±0.22)g/L,均明显低于对照组[分别为1.56(0.96,1.95)mmol/L、(4.78±1.03)mmol/L、(1.42±0.39)mmol/L、(2.50±0.81)mmol/L、(1.39±0.36)g/L、(0.83±0.28)g/L],差异均有统计学意义(U=-3.805、t=5.009、t=3.968、t=3.666、t=7.755、t=3.491,P值均<0.001)。病例组中携带ApoE基因ε2/ε3基因型者的TC、LDL-C、Apo-B水平分别为(3.81±1.21)mmol/L、(2.01±0.79)mmol/L、(0.67±0.22)g/L,均明显低于携带ε3/ε3基因型者[分别为(4.21±1.09)mmol/L、(2.40±0.76)mmol/L、(0.81±0.25)g/L],差异均有统计学意义(t值分别为0.471、5.595、5.681,P值均<0.001)。病例组ApoE基因ε2/ε3基因型频率[13.1%(146/1118)]明显高于对照组[8.4%(49/582)],差异有统计学意义(χ2=8.114,P=0.004);ε2等位基因频率[7.7%(174/2236)]明显高于对照组[5.8%(67/1164)],差异有统计学意义(χ2=4.770,P=0.029)。多因素logistic回归分析显示,携带ApoE基因ε2/ε3基因型[OR(95%CI)=1.763(1.167~2.661)]和ε2等位基因[OR(95%CI)=1.630(1.097~2.421)]是肺结核患病的危险因素。结论: 携带ApoE基因ε2/ε3基因型可能降低肺结核患者的血脂水平;携带ApoE基因ε2/ε3基因型和ε2等位基因人群肺结核患病风险更大。

Abstract:

Objective: To explore the correlation between apolipoprotein E (ApoE) gene polymorphism and blood lipid levels with pulmonary tuberculosis. Methods: A retrospective study was conducted in 1118 patients diagnosed with pulmonary tuberculosis in Meizhou People’s Hospital from January 1, 2016 to December 12, 2020 (case group), and 582 healthy people in the hospital during the same period were selected as the control group. The general information (age, sex) and laboratory test indicators (blood routine test, triglyceride (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), apolipoprotein A1 (Apo-A1), apolipoprotein B (Apo-B), and ApoE genotyping test results) of the subjects were collected. The distribution of ApoE genotypes, differences in blood lipid levels, and the correlation between ApoE genotypes and blood lipid levels between the case group and the control group were analyzed, and multivariate logistic regression was used to analyze the impact of ApoE genotypes and blood lipid levels on the incidence of pulmonary tuberculosis. Results: The levels of TG, TC, HDL-C, LDL-C, Apo-A1, and Apo-B in the case group were 1.23 (0.76, 1.47) mmol/L, (4.18±1.17) mmol/L, (1.14±0.38) mmol/L, (2.36±0.82) mmol/L, (0.94±0.32) g/L, and (0.79±0.26) g/L, respectively, and were all lower than those in the control group (1.64 (1.07, 2.06) mmol/L, (5.24±1.18) mmol/L, (1.36±0.34) mmol/L, (2.98±0.90) mmol/L, (1.31±0.33) g/L, (0.97±0.29) g/L, respectively), and the differences were statistically significant (U=-12.603, t=17.605, t=12.096, t=13.784, t=22.614, t=12.071, all P values <0.001). The TG, TC, HDL-C, LDL-C, Apo-A1, and Apo-B levels of individuals carrying the ApoE ε2/ε3 genotype in the case group were 1.21 (0.73, 1.38) mmol/L, (3.81±1.21) mmol/L, (1.17±0.36) mmol/L, (2.01±0.79) mmol/L, (0.96±0.32) g/L, and (0.67±0.22) g/L, respectively, lower than those in the control group (1.56 (0.96, 1.95) mmol/L, (4.78±1.03) mmol/L, (1.42±0.39) mmol/L, (2.50±0.81) mmol/L, (1.39±0.36) g/L, (0.83±0.28) g/L, respectively), and the differences were statistically significant (U=-3.805, t=5.009, t=3.968, t=3.666, t=7.755, t=3.491, all P values <0.001). The levels of TC, LDL-C, and Apo-B in patients carrying the ApoE ε2/ε3 genotype in the case group were (3.81±1.21) mmol/L, (2.01±0.79) mmol/L, and (0.67±0.22) g/L, respectively, which were lower than those carrying the ApoE ε3/ε3 genotype ((4.21±1.09) mmol/L, (2.40±0.76) mmol/L, and (0.81±0.25) g/L, respectively), with statistically significant differences (t values were 0.471, 5.595, and 5.681, respectively, all P values <0.001). The genotype frequency of ApoE ε2/ε3 genotype in the case group was 13.1% (146/1118),which was significantly higher than that in the control group (8.4% (49/582); χ 2=8.114, P=0.004). ε2 allele frequency in the case group (7.7% (174/2236)) was significantly higher than that of the control group (5.8% (67/1164); χ 2=4.770, P=0.029). Multivariate logistic regression analysis showed that carrying the ApoE ε2/ε3 genotypes (OR (95%CI)=1.763 (1.167-2.661))and ε2 allele gene (OR (95%CI)=1.630 (1.097-2.421)) were risk factors for pulmonary tuberculosis. Conclusion: Carrying ApoE ε2/ε3 genotype may lower the blood lipid levels in pulmonary tuberculosis patients, and carrying ApoE ε2/ε3 genotypes and ε2 allele population has a higher risk of developing pulmonary tuberculosis.
