Total lymphoid irradiation
1Harvard Medical School, Boston, Massachusetts.
Total lymphoid irradiation (TLI) was shown to have potent immunosuppressive effects in patients with Hodgkin's disease. In the last decade a handful of studies assessed the efficacy of TLI in patients with rheumatoid arthritis. A correlation between decline in T-helper cell number and a reduction in disease activity was noted in all studies; however, the toxicity of TLI remains a major problems limiting a more widespread use of this treatment modality.
