AB To determine the serologic cross-reactivity between human T-cell
lymphotropic virus type I (HTLV-I) and parasite antigens, we measured
antibody responses against HTLV-I, Plasmodium falciparum, Plasmodium
vivax, and Brugia malayi in serum specimens obtained from regions where
malaria (n = 482) and filariasis (n = 101) are endemic. Analysis of
immune reactivity to HTLV-I antigens showed that specimens from regions
where malaria is endemic had significantly higher rates of enzyme
immunoassay (EIA) reactivity (76 of 482 [15.8%] than those from regions
where filariasis is endemic (0 of 101 [0%]). Western blot (immunoblot)
analysis of the HTLV-I EIA-reactive specimens demonstrated predominant
Gag reactivity (HTLV-Iind). Only two specimens each from Indonesia and
Brazil and four specimens from Papua New Guinea had Env reactivity by
radioimmunoprecipitation analysis. Furthermore, a positive correlation
between HTLV-EIA and titers of antibody to the blood stage of P.
falciparum (rs = 0.24, P < 0.005) was discerned; no correlation was
observed between antibodies to the blood stage or the circumsporozoite
protein of P. vivax and the circumsporozoite protein of P. falciparum.
In addition, P. falciparum-infected erythrocyte lysate specifically
abrogated binding of Gag-specific antibodies in HTLV-Iind specimens from
regions where malaria is endemic without affecting binding in
HTLV-I-seropositive specimens, suggesting that the immunologic
cross-reactivity between HTLV Gag proteins and malaria parasites is
restricted to the blood-stage antigens of plasmodia in specimens from
regions where malaria is endemic.(ABSTRACT TRUNCATED AT 250 WORDS)
