ABSTRACT
Objective To evaluate the value of the four kinds of diagnostic method in acquired immune deficiency syndrome (AIDS) infection complicating tuberculosis (TB) .Methods 52 cases of human immunodeficiency virus (HIV) infection complica‐ting TB were taken as the observation group and 100 cases of TB without complicating HIV infection were taken as the control group .The two groups were performed the PPD test ,sputum Mycobacterium tuberculosis culture ,tuberculosis antibody and inter‐feron gamma release assay(IGRA) for conducting the diagnosis .Results The positive rate of the PPD test ,sputum Mycobacterium tuberculosis culture and tuberculosis antibody in the control group were significantly higher than those in the observation group ,the differences were statistically significant (P<0 .01);the positive rate of the IGRA in the observation group was obviously higher than that of the PPD test ,sputum Mycobacterium tuberculosis culture and tuberculosis antibody ,the differences had statistical sig‐nificance (P<0 .01) .The negative occurrence rate of the IGRA in the observation group treated by the antiretroviral therapy was obviously higher than the positive rate ,the difference was statistically significant (P<0 .05) .Conclusion The IGRA may be a sen‐sitive method for diagnosing HIV infection complicating TB and the antiretroviral therapy may have a certain impact on the results .
