The Mycobacterium tuberculosis antigen ESAT-6 has been proposed for tuberculosis immunodiagnosis. In The Gambia, 30% of community controls produced gamma interferon (IFN-gamma) in response to ESAT-6. Increased proportions of responders and intensities of responses were found in household contacts. Responses that were initially low in tuberculosis patients increased after treatment. An ESAT-6 IFN-gamma assay will be of limited use in the diagnosis of tuberculosis in countries where tuberculosis is endemic. Its role in contact tracing should be evaluated further.
结核分枝杆菌抗原ESAT-6已被用于结核病的免疫诊断。在冈比亚,30%的社区对照者对ESAT-6产生γ干扰素(IFN-γ)。在家庭接触者中,应答者比例和应答强度均有所增加。结核病患者最初较低的应答在治疗后有所增加。在结核病流行的国家,ESAT-6 IFN-γ检测在结核病诊断中的应用将受到限制。其在接触者追踪中的作用应进一步评估。
