艾滋病合并结核病临床特征复杂多样,影像学征象不典型,诊断困难。CD4 T淋巴细胞是人类主要的免疫调节细胞,它在干预机会性感染,控制HIV发展为AIDS方面为临床医务工作者起着指导性作用。CD4 T淋巴细胞数与结核病的发病率成反比,与肺部影像学征象发生的几率具有相关性,即CD4 T淋巴细胞数值越小,合并结核的可能性越大,肺部影像学征象越不典型。
AIDS complicated with complicated clinical features of tuberculosis, radiographic signs are not typical, diagnosis is difficult. CD4 T lymphocytes are the major human immunoregulatory cells that play a guiding role for clinicians in intervening in opportunistic infections and in controlling the development of HIV for AIDS. The number of CD4 T lymphocytes is inversely proportional to the incidence of tuberculosis and is correlated with the incidence of lung imaging signs. That is, the smaller the number of CD4 T lymphocytes, the greater the possibility of tuberculosis, and the lesser the signs of pulmonary imaging typical.
