Abstract

　　Objective：To explore special iconographic features in cases with AIDS complicated by pulmonary tuberculosis and its relativity to the CD4T lymphocytes.

　　Materials：and Methods：A retrospective analysis was carried out on the display of chest X－rays of cases with late stage AIDS complicate by pulmonary tuberculosis （n＝26 cases） and patients with simple pulmonary tuberculosis （n＝60 cases） and results of examination of the CD4T lymphocytes.

　　Results：（1） Results of the chest plates revealed that：patients with AIDS complicated by pulmonary tuberculosis showed presence of a higher number of light flaky and blurring shadows

than those with simple pulmonary tuberculosis （53.8％ vs，8.3％；P<0.001） with more military tuberculosis （23.1％ vs.5％，P<0，05），enlarged intrathoracic lymph nodes （34.6％ vs 8.3％；p<0.001） as well as presence of extra－pulmonary tuberculous processes （23.1％ vs. 3.3％；p<0.05）；while revealing less number of lesions appearing in the upper lung field or in the apices of the lungs.（23.1 vs. 76.7％；p<0.001），presence of more parenchymatous changes or augmented shadows of uneven densities （11.5％ vs. 71.7％；p＝0.001），accompanied by shadows of cavitation 7.7％ vs. 30％；p＝0.005）；however，no significant difference was found in occurrence of hydrothorax in both the two groups （11.5％ vs. 20％；p>0，05）.（2） Results from examination of the CD4T lymphocytes revealed that：relative numbers of CD4T lymphocytes in patients suffering from AIDS complicated by pulmonary tuberculosis and that with simple pulmonary tuberculosis were 4.99±6.40％ and 65.3±15.2％ respectively；in 15 out of the 26 cases of AIDS patients complicated by pulmonary tuberculosis showing a CD4T lymphocytic count <50/ul suffered all from atypical pulmonary tuberculosis，in 4 with their count of 50/ul～100/ul 3 suffered from atypical pulmonary tuberculosis while in cases with their CD4T lymphocytic count was between 100/ul ～200/ul （n＝4） and >200/ul （n＝2），numbers of atypical tuberculosis were 2 and zero respectively.
