Abstract:

Objective: To analyze the changes of serum tumor necrosis factor superfamily member 14 (TNFSF14) and Soluble interleukin 2 receptor (sIL 2R) levels in elderly patients with pulmonary tuberculosis and their correlation with short-term prognosis. Methods: A total of 80 elderly patients with pulmonary tuberculosis who admitted to the First Hospital of Changsha City from June 2019 to July 2022 were selected as the observation group, and other 80 elderly healthy persons who received physical examinations during the same period were selected as the control group. The patients in observation group were followed up for 3 months after treatment and were divided into good prognosis group (65 cases) and poor prognosis group (15 cases) according to their short-term prognosis. Logistic regression was used to analyze the relevance between serum TNFSF14, sIL-2R and short-term prognosis. Results: The serum TNFSF14 level and sIL-2R level in the observation group were (12.55±1.20) ng/L and (255.80±25.15) pmol/L respectively, which were higher than those in the control group ((3.80±0.53) ng/L and (100.96±10.10) pmol/L). The differences were statistically significant (t=9.434, P<0.001; t=8.166, P<0.001). After the patients in the observation group received treatment, a 3-month follow-up found that 10 cases (12.50%) were cured, 55 cases (68.75%) were effective and 15 cases (18.75%) were ineffective. So a total of 65 cases (81.25%) had good prognosis, while 15 cases (18.75%) had poor prognosis. The serum TNFSF14 level and the serum sIL-2R level of the patients in the poor prognosis group were (14.35±1.51) ng/L and (275.64±27.10) pmol/L respectively, which were higher than those in the good prognosis group ((12.09±1.18) ng/L and (253.33±25.13) pmol/L). The differences were statistically significant (t=6.334, P<0.001; t=3.055, P=0.003). The positive rate of sputum bacteria in poor prognosis group (93.33% 14/15) was higher than that in good prognosis group (58.46%, 38/65), and the difference was statistically significant (χ2=6.515, P=0.011). Logistic regression analysis results showed that the increased levels of serum TNFSF14 (OR=8.913, 95%CI: 1.993-48.002), sIL-2R (OR=7.132, 95%CI: 1.054-35.172) and positive sputum bacteria (OR=9.947, 95%CI: 1.233-80.253) were risk factors for poor prognosis in elderly patients with pulmonary tuberculosis. The results of ROC curve showed that the AUC of serum TNFSF14 alone, sIL-2R alone and their combination in predicting the short-term prognosis of elderly patients with pulmonary tuberculosis were 0.703 (95%CI: 0.549-0.857), 0.726 (95%CI: 0.579-0.873) and 0.901 (95%CI: 0.818-0.999), respectively. Conclusion: Serum TNFSF14 and sIL-2R are at high levels in elderly patients with pulmonary tuberculosis, and the high level of TNFSF14 and sIL-2R will increase the risk of short-term poor prognosis in patients. In clinical practice, the levels of both serum TNFSF14 and sIL-2R should be closely monitored to predict the occurrence of poor prognosis in patients.
