AB BACKGROUND: The incidence of transfusion transmission of human
T-lymphotropic virus type I (HTLV-I) and HTLV type II (HTLV-II) has not
been compared directly or to that of human immunodeficiency virus type 1
(HIV-1). The effects of refrigerator storage of the blood component on
infectivity of the viruses needs definition. STUDY DESIGN AND METHODS:
The circumstances influencing the transmission of HTLV-I, HTLV-II, and
HIV-1 via blood of donors whose sera were stored in a repository and who
were retrospectively documented as having been infected at blood
donation were examined. Confirmation and typing of anti-HTLV positivity
in donors and recipients used polymerase chain reaction, supplemented by
specific peptide testing. RESULTS: Overall, 27 percent (26/95) of the
recipients of blood components from anti-HTLV-I- and -II-positive donors
became infected (9 with HTLV-I and 17 with HTLV-II). No recipients of
acellular blood components became infected with HTLV-I or -II. There was
no probable transmission by components stored > 10 days. The rates of
transmission for both viruses were similar: 0 to 5 days' storage, 17
(74%) of 23; 6 to 10 days, 8 (44%) of 18; and 11 to 14, 0 (0%) of 10
(trend, p = 0.0002). In comparison, 89 percent (112/126) of the
recipients of anti-HIV-1-positive blood were infected regardless of
component type, and no effect on transmission occurred with storage for
< 26 days. CONCLUSION: Transfusion-transmitted HTLV-I and -II are
similar. The data suggest that a donor's lymphocytes become
noninfectious when they lose the ability to be activated or to
proliferate.
