阿拉伯酸甘露聚糖检测对肺结核的诊断价值

Clinical value of LAM-IgG in diagnosing pulmonary tuberculosis

目的评价阿拉伯酸甘露聚糖（ＬＡＭ－ＩｇＧ）检测对活动性肺结核的诊断价值。 方法采用结明（ＭｙｃｏＤｏｔＴＭ）结核病快捷诊断试剂盒检测４７１例结核患者、１０２例非结核患者血清中ＬＡＭ－ＩｇＧ。结果ＬＡＭ－ＩｇＧ诊断活动性结核病的敏感性为６４．０％，特异性为８３．３％。诊断活动性肺结核的敏感性为８０．５％。肺结核患者ＬＡＭ－ＩｇＧ与痰结核菌涂片一致率为 ６４．１％。 ４５５例活动期肺结核患者随病情恢复阴转率为 ７３．６％。结论血清 ＬＡＭ－ＩｇＧ测定是结核病一项有效的辅助诊断方法。

Objective To evaluate the clinical value of LAM-IgG in diagnosing active pulmonary tuberculosis. Methods The serum LAM-IgG of 471 tuberculosis patients and 102 non-tuberculosis patients were detected with tuberculosis quick diagnostic outfit. Results The sensitivity of LAM-IgG in diagnosing active tuberculosis was 64 percent, the specificity was 83. 3 percent. In diagnosing active pulmonary tuberculosis the sensitivity was 80. 5 percent. The positive consistency between serum LAM-IgG and sputum examination for tubercle bacillus was 64. 1 percent. Among active pulmonary tuberculosis patients 73. 6 percent recovered. Conclusion Serum LAM-IgG is proved to be a useful anxiliary examination in diagnosing pulmonary tuberculosis.
