Abstract

Serum samples obtained from human immunodeficiency virus (HIV)-infected tuberculosis (TB) patients months prior to clinical TB were used to delineate the profile of Mycobacterium tuberculosis culture filtrate proteins recognized during subclinical TB. A subset of approximately 12 antigens was recognized by antibodies in these serum samples. Antibodies to two of these antigens (81 [88]-kDa malate synthase [GlcB] and MPT51) were present in serum samples obtained during incipient subclinical TB in 19 (approximately 90%) of the 21 HIV-infected TB patients tested. These antigens will be useful for devising diagnostic tests that can identify HIV-positive individuals who are at a high risk for developing clinical TB.

摘要

从人类免疫缺陷病毒(HIV)感染的结核病(TB)患者临床结核病出现前数月采集的血清样本,用于描绘亚临床结核病期间所识别的结核分枝杆菌培养滤液蛋白谱。这些血清样本中的抗体识别出约12种抗原的一个子集。在接受检测的21名HIV感染的TB患者中,19名(约90%)在初期亚临床结核病期间采集的血清样本中存在针对其中两种抗原(81[88]kDa苹果酸合酶[GlcB]和MPT51)的抗体。这些抗原将有助于设计诊断测试,以识别有发展为临床结核病高风险的HIV阳性个体。
