In the United States, all blood used for transfusion is tested for
the presence of antibodies to the structural components of the human
T-cell lymphotropic viruses types 1 and 2 (HTLV-1 and -2). Based on
such serologic tests, the prevalence of HTLV-1 infection is estimated
to range from 0.016 to 0.1%. As a consequence of studies of patients
with mycosis fungoides and some of their healthy relatives who are
antibody negative but were found to carry the tax sequence
of HTLV-1 in their lymphocytes and who had antibodies to the
p40tax protein, a study was undertaken to
determine the prevalence of the "tax-only" state in 250 healthy blood donors and other volunteers. Using PCR and Southern
analysis for cell lysates and using Western blotting for plasmas, 8.6%
of the blood donors proved to be tax sequence positive and
antibody positive. Sequence analysis of specimens from 22 individuals
proved that 20 of the sequences were homologous with that of HTLV-1
while 2 resembled the HTLV-2 sequence. The latter were obtained from
volunteers of Indian origin. The possible clinical significance of the
tax-only carrier state is discussed.
