| Outline of Final Research Achievements |
Interleukin-6 (IL-6) is thought to play a part of role in the pathogenesis of systemic sclerosis. To know the influence of anti-interleukin 6 receptor antibody tocilizumab (TCZ) which can inhibit the function of IL-6 to the patients with systemic sclerosis, we conduct a clinical trial using TCZ. We analyzed 23 kinds of cytokines, chemokines in the sera of the entry patients to know the effect of TCZ. The patients who showed decrease of skin score presented transiently augmentations of IL-6, IL-8, IL-1beta, and MIP-1alfa. They also presented decrease of IL-10、IL-12、and IL-9 parallel to decrease of their skin score. We have not found out the correlation between the IL-6 level before initiating TCZ and the changes of skin score. The decreasing cytokines may be noteworthy to make a new treatment strategy.
