 AB    Although the cause of amyotrophic lateral sclerosis (ALS) remains
       unknown, recent studies have suggested an autoimmune mechanism of
       pathogenesis. Previous trials of immunosuppressive treatment have
       yielded inconclusive results. Our study was designed to determine
       whether more powerful and prolonged immunosuppression, produced by total
       lymphoid irradiation (TLI), would alter the course of ALS. In a
       double-blind, randomized, placebo-controlled study, 30 patients with
       classic ALS were treated with TLI, and 31 were given sham radiation.
       Quantitative measurements of muscle strength, functional motor activity,
       and humoral and cellular immune status were followed for 2 years, or
       until death or respirator dependence. Motor function in the TLI-treated
       and control groups showed no significant differences throughout the
       study. Overall survival was not significantly different in the
       TLI-treated and control groups. TLI effectively suppressed cellular and
       humoral immune function throughout the 2-year study period. Analysis of
       the relationship between immunosuppression and motor functions showed no
       consistent effect of treatment. We conclude that powerful and prolonged
       immunosuppression produced by TLI did not benefit patients with ALS.
       This fails to support the concept of an autoimmune mechanism of
       pathogenesis of ALS.
