儿结核病结核抗体检测的诊断价值
JOURNAL OF BENGBU MEDICAL COLLEGE(2001)
Abstract
目的:探讨结核菌纯蛋白衍化物(PPD)及抗脂肪阿拉伯酸甘露聚糖抗体(LAM-IgG)对小儿结核病的诊断价值。方法:检测66例结核病患儿血清抗LAM-IgG和PPD试验,并与30例非结核病患儿进行对照。结果:小儿结核病PPD试验阳性率为59.1%,抗LAM-IgG阳性率为69.7%,两者差异无显著性(P>0.05)。PPD试验对非重症结核病阳性率(79.5%)明显高于重症结核(18.2%)(P<0.005);而抗LAM-IgG重症结核病阳性率(70.5%)与非重症结核病(68.2%)相近(P>0.05)。PPD试验对非结核病患儿的假阳性率(36.7%)明显高于抗LAM-IgG试验(3.3%)(P<0.01)。结论:PPD试验对非重症结核病诊断价值优于重症结核病;抗LAM-IgG检测对重症结核病的诊断优于PPD试验,对非结核病的假阳性率较低。
