Abstract
Tocilizumab (TCZ), a biologic that blocks the signal transduction of interleukin-6, has been used for the treatment of various autoimmune diseases. Many of these cases are sometimes complicated by ulcerative colitis (UC). However, the effect of TCZ on UC is unclear. We experienced two cases with concomitant UC that were treated with TCZ, one for Takayasu arteritis (TAK) and the other for relapsing polychondritis (RP). TCZ did not improve UC in either of these cases. TCZ might have adverse effects on the intestinal tract, since interleukin-6 signaling plays an important role in intestinal epithelium maintenance. Treatment with TCZ should therefore be carefully provided in patients complicated with UC.
