摘要:
Objective:To investigate the CT features of patients with type 2 diabetes mellitus complicated with pulmonary tuberculosis.Methods:98 patients with type 2 diabetes comphcated with pulmonary tuberculosis were selected as research group;100 cases of non diabetic patients with pulmonary tuberculosis treated at the same period were selected as control group;the clinical data and CT imaging features were compared between the two groups.According to the duration of diabetes,research group was further divided into the study group A (DM duration ≥ 10 years,n =50) and the study group B (DM duration < 10 years,n =48)to compare the effects of different diabetic courses on the clinical data and CT imaging features.Results:In the study group,61 (63.26%) cases had comorbidities,such as hypertension,chronic renal failure,heart failure and arrhythmia,which were significantly higher than those in the control group,differences were statistically significant (P <,0.001).Double lung lesions (OR,2.39;95% CI,1.34 ~4.25;P =0.003),all lobe lesion (OR,2.79;95% CI,1.24 ~6.27;P =0.013) and lymphadenopathy (OR,1.98;95% CI,1.10~3.55;P=0.022) were independent predictors of DM with TB.The average age of the patients in the study group A was higher than that in the study group B (P < 0.05).There was no significant difference in CT imaging between two groups of TB patients with different DM courses (P > 0.05).Conclusion:Patients with type 2 diabetes mellitus complicated with pulmonary tuberculosis infection CT imaging showed bilateral lung lesions,involving all lung and lymph nodes;CT can help strengthen the diagnosis of patients and provide the basis and reference for the clinical treatment.%目的:探讨2型糖尿病(DM2)并发肺结核(TB)感染患者的CT影像特征.方法:DM2并发TB感染患者98例作为研究组,同时选取同期入院治疗的TB非糖尿病(DM)患者100例作为对照组,对比两组患者的临床资料及CT影像特征;研究组中根据DM病程长短进一步将研究组分为研究组A(DM病程≥10年,n=50)和研究组B(DM病程<10年,n=48),对比不同DM病程患者临床资料及CT影像特征.结果:研究组患者中61例(63.26%)具有高血压、慢性肾功能不全、心衰、心律失常等合并症,显著高于对照组患者,差异有统计学意义(P<0.001);双肺病变(OR,2.39;95% CI,1.34 ~4.25;P =0.003)、所有肺叶病变(OR,2.79;95% CI,1.24~6.27;P=0.013)以及淋巴结肿大(OR,1.98;95% CI,1.10 ~3.55;P =0.022)均为DM合并TB的独立预测因素;在研究组中,研究组A患者的平均年龄高于研究组B患者(P<0.05);两组不同病程DM2合并TB患者的CT影像学表现差异无统计学意义(P>0.05).结论:DM2合并TB患者的CT检查有明显示影像子特征,认识这些特征有助于准确诊断和临床治疗方案的选择.
