THE RESULTS OF APPLICATION OF IN VITRO AND IN VIVO IMMUNOLOGICAL METHODS OF TUBERCULOSIS DIAGNOSTICS IN HIV-PATIENTS
Abstract
We analized the results of application of skin test with Diaskintest® and T-SPOT®.TB laboratory test in 75 HIV-patients with lung TB. It was found, that percentage of positive results consisted of 60.0% (95%CI 48.7–70.4%) using T-SPOT®.TB test and 22.7% (95%CI 14.6–33.4%) using skin test. Moderate correlation relationship of results of both tests and number of CD4+ Т-cells was shown. The percentage of positive results using T-SPOT®.TB in patients with number of CD4+ Т-cells from 50 cells/μl and more was significantly higher than those one in patients with number of CD4+ Т-cells lower than 50 cells/μl (81.1% against 9.1%, according to χ2, p < 0,01). The results of both tests coincided in 48.0% of cases and were discordant in 52.0%, coherence of the tests was low (κ = 0.17; р < 0.05). The given results allow us to conclude that using T-SPOT®.TB test was highly effective in HIV-patients with lung TB. The limitation for the test application was severe immunosuppression with number of CD4+ Т-cells lower than 50 cells/μl.
