Figure 5. Correlation of IL-13 Production with Ulcerative Colitis Clinical Activity.
This patient received two courses of interferon-β-1a. The solid line charts the SCCAI decreasing to clinical remission (SCCAI ≤ 2) during treatment (shaded area) and follow-up and indicating a relapse of symptoms at Week 36. Serial measurements of IL-13 production (dotted line) show that it declines with induction of remission and increased in conjunction with clinical relapse.
