T-cell vaccination against anti-CD4 autoimmunity in HIV-1 subtypes B and C-infected patients--an extended open trial.

This study is an extended clinical trial of the one initiated and reported in the Journal of Clinical Virology 2004;31S:S48-54. Thirteen HIV-1 patients (eight subtype B and five subtype C) that manifested T-cell autoimmunity to recombinant human CD4 (rCD4) were treated with T-cell vaccine composed of glutaraldehyde-treated autologous anti-CD4 reactive T-cells and compared to historical seven non-vaccinated HIV-1-infected subjects. This study proved to be feasible and safe.
