Abstract

BACKGROUND: No therapies have been proven to persistently improve the outcome of HTLV-I-associated myelopathy. Clinical benefit has been reported with zidovudine and with lamivudine in observational studies. We therefore conducted a randomised, double blind, placebo controlled study of six months combination therapy with these nucleoside analogues in sixteen patients. RESULTS: Primary outcomes were change in HTLV-I proviral load in PBMCs and clinical measures. Secondary endpoints were changes in T-cell subsets and markers of activation and proliferation. Six patients discontinued zidovudine. No significant changes in pain, bladder function, disability score, gait, proviral load or markers of T-cell activation or proliferation were seen between the two arms. Active therapy was associated with an unexplained decrease in CD8 and non-T lymphocyte counts. CONCLUSION: Failure to detect clinical improvement may have been due irreversible nerve damage in these patients with a long clinical history and future studies should target patients presenting earlier. The lack of virological effect but may reflect a lack of activity of these nucleoside analogues against HTLV-I RT in vivo, inadequate intracellular concentrations of the active moiety or the contribution of new cell infection to maintaining proviral load at this stage of infection may be relatively small masking the effects of RT inhibition.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Contrary to the HIV field, success in treating retroviruses with ART has not been imitated in the treatment of HTLV-1.

    “yet, contrary to the HIV field, such success has not been imitated in the treatment of HTLV-1 [159,160,161].”

    From Current State of Therapeutics for HTLV-1 (2024) · cites this paper as [161]

    The Results and Conclusion (no page number available) report no significant clinical or proviral-load benefit from zidovudine plus lamivudine in patients with HTLV-1-associated myelopathy. That supports a lack of success for this regimen in this condition, but does not establish that antiretroviral treatment has been unsuccessful across HTLV-1 disease generally. (LLM, conf=0.84)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
