摘  要:目的分析单纯结核病患者(TB)、糖尿病并发肺结核患者(DM-TB)、糖尿病患者(DM)以及健康人群(HC)血清γ干扰素(IFN-γ)与白细胞介素-10(IL-10)水平的差异,探讨不同细胞因子在糖尿病并发结核病中的作用。方法选取江苏、江西两省4个县(区)2013年4月1日至2014年3月31日期间确诊的DM-TB患者71例作为DM-TB组;按照1:1以及年龄、性别匹配的原则,选取同期诊断的涂阳TB患者71例(TB组)、社区DM患者71例(DM组),以及社区健康人群71名(HC组)作为对照。收集研究对象的基本信息,采集血样并用酶联免疫吸附法检测血清IFN-γ和IL-10水平,进行对比分析。结果DM-TB组、TB组、DM组、HC组血清IFN-γ水平中位数(四分位数)[M(Q1-Q3)]分别为7.51(4.64-14.47)、8.76(4.26-15.03)、9.15(2.47-13.72)、2.20(1.62-6.65)ng/L,数值经对数转换后分别为2.06±0.91,2.15±1.13,1.73±1.35,1.26±1.62,各组间比较差异有统计学意义(F=6.98,P〈0.01);进一步两两比较后发现,与HC组相比,DM-TB组和TB的血清IFN-γ水平均明显增高(P值分别为0.002、〈0.01)。DM-TB组、TB组、DM组、HC组血清IL-10水平[M(Q1-Q3)]分别为16.44(6.25-33.31)、14.06(4.73-25.67)、7.55(2.53-21.25)、4.64(2.66-7.67)ng/L,数值经对数转换后分别为2.67±0.99,2.20±1.59,1.63±2.02,1.58±0.99,各组间比较差异有统计学意义(F=7.96,P〈0.01);进一步两两比较发现,与DM-TB组相比,DM组和HC组的血清IL-10水平均明显降低(P值分别为0.001、〈0.01)。多因素线性回归分析发现,DM-TB组患者血清IFN-γ浓度明显高于HC组(P=0.001),男性患者血清IL-10水平明显高于女性(P=0.046);DM-TB组血清IL-10水平明显高于DM组(P〈0.01)和HC组(P〈0.01)。结论DM-TB患者�Objective To compare the serum levels of interferon-gamma (IFN-7) and interleukin-10 (IL-10) in patients with tuberculosis (TB), tuberculosis with diabetes mellitus (DM-TB), diabetes mellitus (DM) and healthy control (HC) people, and to analyze the role of different cytokines in DM-TB. Methods A total of 71 DM-TB patients in four counties of Jiangsu and Jiangxi provinces were selected between April 1, 2013 to March 31, 2014. At the same study period, 71 age- and gender-matched smear-positive TB patients, community DM patients and community healthy controls were selected, respectively, according to the ratio of 1:1:1. The baseline charac- teristics of all subjects were collected, and the serum levels of IFN-γ and IL-10 were measured by enzyme-linked im- munosorbent assay (ELISA). The levels were compared among different subject groups. Results The median (quartile) levels of serum IFN-γ of DM-TB, TB, DM patients and HC were 7.51 (4.64-14. 47), 8.76 (4. 26-15.03), 9.15 (2.47-13.72), 2.20 (1.62-6.65) ng/L, respectively. The numbers were 2. 06±0.91, 2.15 ± 1.13, 1.73± 1.35 and 1.26±1.62 after logarithmic conversion. There were significant differences among four groups (F=6. 976, P〈0.01). The results of multiple comparison post hoc test showed that concentration of IFN-γ was increased in DMTB and TB patients compared with HC group (P=0. 002, P〈0.01). The median (quartile) level of serum IL-10 of DM-TB, TB, DM and HC were 16.44 (6.25 33.31), 14. 06 (4. 73-25.67), 7.55 (2. 53- 21.25) and4.64 (2.66-7.67) ng/L, respectively. The numbers were 2.67±0.99, 2.20±1.59, 1.63±2.02 and 1.58±0.99 after logarithmic conversion. There were significant difference among groups (F=7.96, P〈0.01). The results of multiple comparison post hoc test showed that serum level of IL-10 in DiM and HC group were signifi- cantly lower than that in the DM-TB group (P= 0. 001, P〈0.01). Multivariate linear regression analysis showed that the serum
