Mycobacterial infection in HIV+ patients detected with a new immunological method (TB test)

Allerg Immunol (Paris). 1993 Jan;25(1):24-5.

Abstract

Antibody response to antigen A60 (a mycobacterial antigen) was evaluated in ELISA in 18 HIV+ subjects with clinical and cultural evidences of mycobacterial infections, in 10 HIV+ subjects without Mycobacterial infections and in 22 healthy donors. We found higher levels of specific IgG in the HIV+ patients with Mycobacterial infections (mean 179.2 +/- 83 U) compared to the values of the donors (mean 92.5 +/- 35.5 U: p < 0.01). This test may be useful in the diagnosis of tuberculosis, but it needs clinical validation.
