摘要:

目的: 探讨慢性非免疫系统性疾病对γ-干扰素释放试验(IGRA)检测结核感染敏感性的影响。方法: 采用回顾性研究方法,按照IGRA阳性∶阴性约1∶1的比例从电子病历中分别收集2024年1—10月河北医科大学第二医院住院且相关临床资料(包括有结核病及慢性非免疫系统性疾病临床诊断、IGRA检测结果及斑点数,以及与上述多种疾病密切相关的年龄和性别数据等)完整的3057例患者。排除125例现患结核病和98例有结核病病史的患者后纳入2834例患者作为研究对象,以分析慢性非免疫系统性疾病对IGRA检测结核感染敏感性的影响。结果: 2834例无明确结核感染证据的患者中,男性1534例(54.13%),女性1300例(45.87%);年龄范围为4月龄至98岁,年龄中位数(四分位数)为57.0(37.0,68.0)岁;IGRA阳性和阴性者分别为1300例(45.87%)和1534例(54.13%);合并贫血、低蛋白血症、糖尿病、高血压、乙型病毒性肝炎、肿瘤者分别为531例(18.74%)、591例(20.85%)、541例(19.09%)、965例(34.05%)、96例(3.39%)、709例[25.02%;包括恶性肿瘤393例(55.43%)、疑似恶性肿瘤78例(11.00%)、良性肿瘤238例(33.57%)]。多因素logistic回归分析显示,与女性、未合并糖尿病和0~9岁年龄组相比,男性、合并糖尿病、10~19岁组、20~49岁组和50~98岁组患者IGRA阳性的风险均明显增加[OR(95%CI)值分别为1.773(1.507~2.085)、1.453(1.183~1.785)、3.405(1.143~10.142)、22.070(8.027~60.678)和45.822(16.732~125.486)];与无贫血患者相比,合并贫血患者IGRA阳性的可能性降低[OR(95%CI)=0.591(0.477~0.732)]。结论: 贫血可能会导致IGRA检测结核感染的假阴性结果,而糖尿病则可能导致假阳性结果或致结核感染的可能性升高,提示临床应对上述合并症患者的IGRA结果谨慎解读,避免误诊。

Abstract:

Objective: To investigate the effect of chronic non-immune system diseases on the sensitivity of interferon-gamma release assay (IGRA) for detection of tuberculosis (TB) infection. Methods: A retrospective study was conducted. Electronic medical records of inpatients at the Second Hospital of Hebei Medical University from January to October 2024 were collected. A total of 3057 inpatients with complete clinical data were selected, following an approximate 1∶1 ratio of IGRA-positive to IGRA-negative cases. The data included clinical diagnosis of TB or chronic non-immunological diseases, IGRA results, and spot-forming cell counts, as well as age and gender data closely related to the above diseases. After excluding 125 patients with active TB and 98 with a history of TB, 2834 patients were included to analyze the effect of chronic non-immune diseases on the sensitivity of IGRA for detection of TB infection. Results: Among the 2834 patients without definitive evidence of TB infection, 1534 (54.13%) were male and 1300 (45.87%) were female, with an age range of 4 months to 98 years (median (IQR): 57.0 (37.0, 68.0) years). There were 1300 (45.87%) IGRA-positive and 1534 (54.13%) IGRA-negative cases. Patients with comorbidities included anemia (531, 18.74%), hypoalbuminemia (591, 20.85%), diabetes (541, 19.09%), hypertension (965, 34.05%), hepatitis B (96, 3.39%), and tumors (709, 25.02%). Among tumor cases, 393 (55.43%) were malignant tumors, 78 (11.00%) were suspected malignancies, and 238 were (33.57%) benign tumors. Multivariate logistic regression analysis showed that, compared to females, non-diabetics, and the 0-9 years age group, the risk of a positive IGRA was significantly increased in males, patients with diabetes, and those in the 10-19, 20-49, and 50-98 years age groups (OR (95%CI): 1.773 (1.507-2.085), 1.453 (1.183-1.785), 3.405 (1.143-10.142), 22.070 (8.027-60.678), and 45.822 (16.732-125.486), respectively). Conversely, patients with anemia had a decreased likelihood of a positive IGRA compared to non-anemic patients (OR (95%CI)=0.591 (0.477-0.732)). Conclusion: Anemia may lead to the false-negative results of the IGRA test, whereas diabetes mellitus may lead to the false positivity or increased TB infection. These findings suggest that IGRA results should be interpreted cautiously in patients with these comorbidities to avoid misdiagnosis.
