依赖利福平结核分枝杆菌Rv0341抗体阳性初治肺结核患者的临床特点分析

目的 探讨依赖利福平结核分枝杆菌(简称依R菌)Rv0341抗体阳性初治肺结核患者的临床特点.方法 纳入42例依R菌Rv0341抗体阳性的初治肺结核患者作为研究组,45例依R菌Rv0341抗体阴性的初治肺结核患者作为对照组,对两组的临床症状、X线影像学表现、痰结核分枝杆菌和依R菌培养阳性率、治疗效果等方面进行对比分析.结果 研究组咳痰、咯血、气促的发生率明显高于对照组(P＜0.05);X线影像学表现研究组病变更多累及双肺及多个肺野(P＜o.05),对照组病变更多局限于单肺和一个肺野(P＜o.05),且研究组出现空洞的比率高于对照组(P＜o.05);在痰结核分枝杆菌培养阳性率上两组差异无统计学意义(P＞0.05),但研究组痰依R菌培养阳性率组明显高于对照组(P＜0.05);对照组的治愈、好转率高于研究组(P＜0.05),对照组治疗无效的比例也低于研究组.结论 依R菌Rv0341抗体阳性初治肺结核患者具有临床症状重,病变范围广,易出现空洞,依R菌培养阳性率较高,治疗效果欠佳的特点、.

Clinical features of initially treated pulmonary tuberculosis patients with rifampin dependent mycobacterium tuberculosis Rv0341 antibody positive

Objective To investigate the clinical features of initially treated pulmonary tuberculosis(TB)patients with rifampin dependent mycobacterium tuberculosis Rv0341 antibody positive.Methods Forty two initially treated pulmonary TB patients with rifampin dependent mycobacterium tuberculosis Rv0341 antibody positive were included as the study group and 42 initially treated pulmonary TB patients with rifampin dependent mycobacterium tuberculosis Rv0341 antibody as the control group The aspects of clinical symptoms,X-ray imaging manifestations,positive rate in sputum culture of Mycobacterium tuberculosis and rifampin dependent mycobacterium tuberculosis,treatment effects,etc.were compared between the two groups.Results The incidence rates of expectoration,hemoptysis and shortness of breath in the study group were significantly higher than those in the control group(P＜0.05);the X-ray image manifestations in the study group showed that the lesions were much more involved in two lungs and multiple lung fields(P＜0.05),while thlesions in the control group more confined to single lung and one lung field(P＜ 0.05),moreover the rate appearing pulmonary cavity in the study group was higher than that in the control group(P＜0.05);the sputum culture positive rate of Mycobacterium tuberculosis had no statistical difference between the two groups(P＞0.05),but the sputum culture positive rate of rifampin dependent mycobacterium tuberculosis in the study group was significantly higher than that in the control group(P＜0.05);as for the treatment effects,the cure rate in the control group was higher than that in the study group(P＜0.05),the ineffective ratio in the control group was less than that in the study group.Conclusion Initially treated pulmonary TB patients with rifampin dependent mycobacterium tuberculosis Rv0341 antibody positive have the characteristics of severe clinical symptoms,wide range lesions,easily appearing cavity,high culture positive rate of rifampin dependent mycobacterium tuberculosis and poor treatment effect.
