The study was conducted by Rīga East Clinical University Hospital with data from the HIV-1 register, in collaboration with the RSU Joint Laboratory of Clinical Immunology and Immunogenetics. 200 HIV-1 infected patients and 184 HIV-1 with TB co-infection patients divided in four groups were included in the study. IFN-γ, IL-10, IL-18, IL-1b levels were measured in serum with commercially enzyme-linked immunosorbent assay (ELISA Vector-Best Corporation, Novosibirsk, Russia). CD4 cell counts were measured by flow Partec IVD cytometry (USA). HIV-1 RNA quantification was performed using the COBAS AmpliPrep/COBAS Taqman HIV-1 Test (Germany). All groups were compared with each another. IFN-γ production was significantly lower, and IL-10 and CD4 cell counts were significantly higher, in HIV-1 patients without TB compared with the other groups. The group with HIV-1 and TB had significantly elevated IL-18 production. HIV patients with primary TB had significantly elevated IFN-γ production and HIV-1 RNA viral load and significantly lower IL-10 production.4445040enginfo:eu-repo/semantics/openAccesscytokinesHIV-1IFN-γMycobacterium tuberculosis3.1 Basic medicine1.1.
