摘要:

目的: 探讨母牛分枝杆菌菌苗对HIV合并结核分枝杆菌潜伏感染(latent tuberculosis infection,LTBI)者T细胞亚群的影响及其使用的安全性。方法: 采用多中心前瞻性队列研究方法,连续纳入2003年6月至2020年6月宁夏回族自治区银川市AIDS管理机构管理的经结核菌素皮肤试验筛查确诊的96例HIV感染合并LTBI者作为研究对象。研究对象按照银川市所辖县区划分为试验组(63例)和对照组(33例)。试验组在高效抗逆转录病毒治疗的基础上,注射母牛分枝杆菌菌苗22.5μg/次,每2周注射1次,共3次。对照组在高效抗逆转录病毒治疗的基础上,口服异烟肼300mg/次,1次/d,连续服用6个月。于治疗前和治疗结束后1个月、3个月随访时,检测并比较两组研究对象的CD4+、CD8+、CD3+T细胞等免疫细胞水平及肝功能指标变化情况;同时,评价两组研究对象不良反应发生情况。结果: 试验组在治疗结束后1个月,CD3+T细胞水平为(1583.83±584.69)个/μl,明显高于治疗前 [(1221.20±399.52)个/μl;t=-2.962,P=0.004];治疗结束后3个月,CD3+、CD4+、CD8+ T细胞水平分别为(1816.67±736.86)个/μl、(674.10±282.30)个/μl和(833.21±314.11)个/μl,均明显高于治疗前[分别为(1221.20±399.52)个/μl、(588.71±273.44)个/μl和(609.65±267.71)个/μl],差异均有统计学意义(t=-4.460,P<0.001;t=-2.801,P=0.044;t=-3.801,P<0.001)。治疗结束后3个月,试验组CD3+、CD4+T细胞水平及CD4+/CD8+比值(0.86±0.54),均明显高于对照组[分别为(1716.47±689.07)个/μl、(559.11±187.14)个/μl、0.82±0.74],差异均有统计学意义(t=2.209, P=0.034;t=3.666,P=0.008;t=3.502, P=0.001)。在治疗结束后1个月,对照组谷草转氨酶水平为(33.15±11.70)U/L,明显高于试验组[(26.54±9.63)U/L],差异有统计学意义(t=2.624,P=0.011);治疗结束后3个月,对照组谷丙转氨酶[(52.58±27.72)U/L]、谷草转氨酶[(33.74±11.89)U/L]水平均明显高于试验组[(35.29±21.16)U/L、(26.67±11.07)U/L],差异均有统计学意义(t=2.563,P=0.013;t=2.172,P=0.034)。试验组无不良反应,无退出治疗患者,治疗完成率达到100.0%(63/63),明显高于对照组的84.9%(28/33),差异有统计学意义(χ2=7.235,P=0.007)。结论: 母牛分枝杆菌菌苗用于HIV感染合并LTBI者抗结核预防性治疗可提高其细胞免疫水平,且对肝功能的损伤更小,具有较好的安全性。

Abstract:

Objective: To investigate the effects of Mycobacterium vaccinae on T Lymphocyte subsets in HIV patients complicated with latent tuberculosis infection (LTBI) and its safety. Methods: Using a multicenter prospective cohort study method, 96 HIV patients complicated with LTBI who were confirmed through tuberculin skin test screening and managed by the AIDS management agency in Yinchuan City, Ningxia Hui Autonomous Region from June 2003 to June 2020 were continuously included as the study subjects. The research subjects were divided into experimental group (n=63) and control group (n=33) according to the counties and districts. Based on efficient antiretroviral therapy, the experimental group was injected with Mycobacterium vaccinae (22.5 μg, once every two weeks for three times), and the control group received oral isoniazid (300 mg, once a day, continuously for 6 months). Levels of immune cells such as CD4+, CD8+, and CD3+T cells, as well as changes in liver function indicators between the two groups were measured and compared before treatment and at 1-month and 3-month follow-up after treatment. In addition, the occurrence of adverse reactions in both groups was evaluated. Results: One month after the end of treatment, the level of CD3+T cells in the experimental group was (1583.83±584.69) cells/μl, significantly higher than that before treatment ((1221.20±399.52) cells/μl; t=-2.962, P=0.004). Three months after the end of treatment, the levels of CD3+, CD4+, and CD8+T cells were (1816.67±736.86) cells/μl, (674.10±282.30) cells/μl and (833.21±314.11) cells/μl, significantly higher than those before treatment ((1221.20±399.52) cells/μl, t=-4.460, P<0.001; (588.71±273.44) cells/μl, t=-2.801, P=0.044; and (609.65±267.71) cells/μl, t=-3.801, P<0.001, respectively). Three months after the end of treatment, the levels of CD3+, CD4+T cells, and CD4+/CD8+ ratio (0.86±0.54) in the experimental group were significantly higher than those in the control group ((1716.47±689.07) cells/μl, t=2.209, P=0.034; (559.11±187.14) cells/μl, t=3.666, P=0.008; 0.82±0.74, t=3.502, P=0.001, respectively). One month after the end of treatment, the level of aspartate aminotransferase in the control group was (33.15±11.70) U/L, significantly higher than that in the experimental group ((26.54±9.63) U/L, t=2.624, P=0.011). Three months after the end of treatment, the levels of alanine aminotransferase ((52.58±27.72) U/L) and alanine aminotransferase ((33.74±11.89) U/L) in the control group were significantly higher than those in the experimental group ((35.29±21.16) U/L, t=2.563, P=0.013; and (26.67±11.07) U/L, t=2.172, P=0.034, respectively). The experimental group had no adverse reactions and no patients withdrew from treatment, with a treatment completion rate of 100.0% (63/63), significantly higher than that of the control group (84.9% (28/33), χ2=7.235, P=0.007). Conclusion: The use of Mycobacterium vaccinae for anti-tuberculosis prophylactic treatment in HIV patients complicated with LTBI can improve the cellular immune levels and cause less damage to liver function, indicating good safety.
