Serum antibodies against human T cell leukaemia virus type I (HTLV-I)
were investigated in 12 patients by four methods: indirect
immunoperoxidase staining, indirect immunofluorescence, enzyme linked
immunosorbent assay (ELISA), and strip radioimmunoassay based on the
Western blotting assay. Seven patients had systemic lupus erythematosus
(SLE) and five various autoimmune diseases with one or more circulating
autoantibodies. Serum samples from three patients were found to be
HTLV-I-positive by the ELISA assay and sera from five patients showed a
non-specific reaction by indirect immunofluorescence. These sera were
negative when tested by indirect immunoperoxidase staining and Western
blotting assay. All four methods gave positive results when tested with
samples from 19 HTLV-I carriers and 16 patients with adult T cell
leukaemia. Indirect immunoperoxidase staining and Western blotting assay
are probably useful and more specific assays for the detection of
anti-HTLV-I antibodies in samples from patients with autoimmune
diseases.
