摘要: 目的 探讨C反应蛋白(C reactive protein,CRP)水平在糖尿病合并肺结核患者的糖化血红蛋白(glycated hemoglobin A1c, HbA1c)水平和耐药肺结核发生率间的中介作用。方法 选取2022年1月至2024年12月在青岛市公共卫生临床中心确诊入院的糖尿病合并肺结核患者352例为研究对象,检测CRP水平在HbA1c水平与耐药肺结核发生率间的中介效应,并用bootstrap法进行中介变量验证。结果 糖尿病合并肺结核患者中检出存在耐药肺结核患者85例,检出率24.1%。患者HbA1c水平与CRP水平之间呈正相关(r=0.459,P<0.01);HbA1c水平与耐药肺结核发生率之间呈正相关(r=0.359,P<0.01);CRP水平与耐药肺结核发生率之间呈正相关(r=0.441,P<0.01)。回归分析结果显示,HbA1c水平和CRP水平均对耐药肺结核发生率有影响(β=0.81、β=1.17,均P<0.001)。HbA1c水平对耐药肺结核发生率的总效应值为1.30,直接效应值为0.81,CRP水平对耐药肺结核发生率的中介效应值为0.49,占总效应的37.69%。结论 糖尿病合并肺结核患者的HbA1c水平和CRP水平与耐药肺结核发生率相关,且CRP水平在HbA1c水平和耐药肺结核发生率之间存在部分中介作用。

Abstract: Objective The objective of this study was to explore the mediating role of C reactive protein (CRP) levels in the relationship between glycated hemoglobin A1c (HbA1c) and the occurrence of drug-resistant pulmonary tuberculosis (DR-PTB) in patients with diabetes mellitus-pulmonary tuberculosis. Method A total of 352 patients diagnosed with Diabetes mellitus-pulmonary tuberculosis at Qingdao public health clinical center from 2022 to 2024 were included. To analyze the mediating effect of CRP levels in the relationship between HbA1c and DR-PTB occurrence, with validation performed using the bootstrap method. Result Among the patients, 85 cases (24.1%) were identified with DR-PTB. HbA1c showed positive correlations with CRP levels (r=0.459, P<0.01) and DR-PTB occurrence (r=0.359, P<0.01). CRP levels were also positively correlated with DR-PTB occurrence (r=0.441, P<0.01). Regression analysis indicated that both HbA1c control (β=0.81) and CRP levels (β=1.17) significantly influenced DR-PTB occurrence (P<0.001). The total effect of HbA1c on DR-PTB occurrence was 1.30, with a direct effect of 0.81. The mediating effect of CRP levels was 0.49, accounting for 37.69% of the total effect. Conclusion HbA1c and CRP levels are associated with DR-PTB occurrence in patients with diabetes mellitus-pulmonary tuberculosis,and there is a partial mediating effect of CRP levels between HbA1c and the occurrence of drug-resistant tuberculosis.
