Abstract:
Objective:To investigate the effect of early interventional therapy with fiberoptic bronchoscope in patients with inflammatory infiltrating type (Ⅰ type) tracheobronchial tuberculosis (TBTB).Methods:Using prospective research methods, 306 patients with Ⅰ type TBTB diagnosed by fiberoptic bronchoscopy in the Third People′s Hospital of Kunming City from January 2019 to April 2022 were selected. The patients were divided into observation group and control group according to the random number table method with 153 cases each. The patients in control group were given routine anti-tuberculosis chemotherapy, and the patients in observation group were given routine anti-tuberculosis chemotherapy combined with early interventional therapy with fiberoptic bronchoscope. Sputum smear examination and tuberculosis culture were performed at the end of 1, 3 and 6 months of treatment, and the negative conversion of sputum culture was recorded. Chest X-ray, pulmonary function and fiberoptic bronchoscope were performed at the end of 1, 3 and 6 months of treatment to evaluate the improvement rate of clinical symptoms, effective absorption rate of lesions and effective absorption rate of obstructive pneumonia. The CD 4+, CD 8+, CD 4+/CD 8+, interferon γ (IFN-γ), interleukin-6 (IL-6) and C reactive protein (CRP) before and after treatment were detected. The random walking model of immune inflammation was evaluated. Results:The sputum negative conversion rates at the end of 1, 3 and 6 months of treatment in observation group were significantly higher than those in control group: 64.71%(99/153) vs. 52.29%(80/153), 80.39%(123/153) vs. 62.09%(95/153) and 91.50%(140/153) vs. 73.86%(113/153), and there were statistical differences ( P<0.05 or <0.01). The improvement rate of clinical symptoms at the end of 1 month of treatment in observation group was significantly higher than that in control group: 94.77%(145/153) vs. 66.67%(102/153), and there was statistical difference ( P<0.01); the clinical symptoms disappeared in both groups at the end of 3 and 6 months of treatment. The effective absorption rates of lesions at the end of 1 and 3 months of treatment in observation group were significantly higher than those in control group: 73.20%(112/153) vs. 51.63%(79/153) and 96.73%(148/153) vs. 85.62%(131/153), and there were statistical differences ( P<0.01); all the lesions were absorbed at the end of 6 months of treatment in both groups. The effective absorption rates of obstructive pneumonia at the end of 1 and 3 months of treatment in observation group were significantly higher than those in control group: 78.43% (120/153) vs. 39.87%(61/153) and 89.54%(137/153) vs. 79.08%(121/153), and there were statistical differences ( P<0.01 or <0.05); all obstructive pneumonia were absorbed at the end of 6 months of treatment in both groups. There were no statistical differences in CD 4+, CD 8+, CD 4+/CD 8+, IL-6, IFN-γ and CRP before treatment between the two groups ( P>0.05); the CD 4+, CD 4+/CD 8+ and IFN-γ after treatment in observation group were significantly higher than those in control group: 0.343 ± 0.032 vs. 0.311 ± 0.023, 1.37 ± 0.18 vs. 1.12 ± 0.16 and (38.47 ± 3.50) ng/L vs. (20.52 ± 2.96) ng/L, the CD 8+, IL-6 and CRP were significantly lower than those in control group: 0.251 ± 0.020 vs. 0.268 ± 0.021, (19.40 ± 3.31) ng/L vs. (34.58 ± 5.82) ng/L and (10.41 ± 2.87) mg/L vs. (17.47 ± 3.14) mg/L, and there were statistical differences ( P<0.01). The evaluation results of random walking model showed that CD 4+, CD 8+, CD 4+/CD 8+, IFN-γ, IL-6 and CRP in the observation group were better than those in the control group in the maximum random fluctuation, number of walking steps, positive walking growth rate, random fluctuation power law value, comprehensive improvement rate, recording times of comprehensive evaluation index and expected improvement value. Conclusions:Early interventional therapy with fiberoptic bronchoscope can effectively assist systemic drug therapy in patients with Ⅰ type TBTB, which can accelerate focus absorption, promote sputum negative conversion, enhance cellular immunity and effectively inhibit inflammatory reaction.
