HTLV-I and HTLV-II infections among HIV-1 seropositive patients in Sao Paulo, Brazil.
To estimate the presence of, and the risk factors for HTLV-I and HTLV-II infections among HIV-1 infected subjects in Sao Paulo, Brazil, a serosurvey was performed in 471 HIV-1 infected patients, including 216 intravenous drug addicts (IVDA), 229 homosexual/bisexual men, and 26 with other risk factors.
Serum samples were screened for HTLV seroreactivity by ELISA ; reactive samples were analyzed by Western Blot (WB), using whole HTLV-I lysate as antigen.
To confirm and discriminate HTLV-I and HTLV-II infections, sera presenting any bands on WB were further analyzed by a WB containing recombinant HTLV-I and HTLV-II proteins (WB 2.3), and by enzyme immunoassays using synthetic peptides specific for envelope proteins (Synth-EIA).
