目的探讨血清抗结核抗体在老年肺结核中的应用价值。方法将我院2012年1月~2013年8月收治的280例肺结核患者按不同年龄分为老年组(≥60岁)和青年组(≤30岁),比较发热、咳痰、咳嗽、咳血、乏力、胸痛、盗汗等临床指标和抗结核抗体、涂片、PPD检出阳性结果。结果老年组发热、咳血、盗汗等临床表现发生率低于青年组,咳痰、咳嗽、乏力等临床表现的发生率高于青年组,差异具有统计学意义(P<0.05);老年组抗结核抗体阳性率高于涂片和PPD试验阳性率,但低于青年组抗结核抗体阳性率,差异均具有统计学意义(P<0.05)。结论老年肺结核症状不明显,血清抗结核抗体阳性率虽不及年轻患者,但优于其他检测方法,值得在临床诊断中推广应用。
Objective To investigate the value of serum anti-TB antibody in elderly patients with pulmonary tuberculosis. Methods A total of 280 tuberculosis patients admitted from January 2012 to August 2013 in our hospital were divided into the elderly group (≥60 years old) and the young group (≤30 years old) according to different ages. The patients with fever, sputum, cough and hemoptysis , Fatigue, chest pain, night sweats and other clinical indicators and anti-TB antibodies, smears, PPD positive results detected. Results The incidence of clinical manifestations such as fever, hemoptysis and night sweats in the elderly group was lower than that in the youth group (P <0.05). The incidence of clinical manifestations including sputum, cough and fatigue was higher in the elderly group than in the youth group (P <0.05) The positive rate of tuberculosis antibody was higher than that of smear and PPD test, but lower than the positive rate of anti-TB antibody in young group (P <0.05). Conclusion The symptoms of senile pulmonary tuberculosis are not obvious, although the positive rate of serum anti-tuberculosis antibody is less than that of young patients, but superior to other detection methods, it is worth to be popularized in clinical diagnosis.
