摘  要:Active ulcerative colitis (UC) is frequently associated with infiltration of a large number of leukocytes into the bowel mucosa. Leukocytapheresis is a novel nonphar- macologic approach for active UC, in which leukocytes are mechanically removed from the circulatory system. Current data indicate that leukocytapheresis is effica- cious in improving response and remission rates with excellent tolerability and safety in patients with UC. Corticosteroid therapy remains a mainstay in the treat- ment of active UC, however, long-term, high doses of corticosteroids usually produce predictable and po- tentially serious side effects. If leukocytapheresis can spare patients from exposure to corticosteroids, the risk of steroid-induced adverse events should be mini- mized. This may be of great benefit to patients because severe side effects of steroids seriously impair health- related quality of life. In this article, we reviewed cur- rent evidence on whether leukocytapheresis can avoid or reduce the use of corticosteroids in the manage- ment of patients with UC. Several studies have shown that leukocytapheresis was effective for steroid-nafve patients with active UC. Furthermore, both short-term and long-term studies have demonstrated the steroid- sparing effects of leukocytapheresis therapy in patients with UC. Although the evidence level is not striking, theavailable data suggest that leukocytapheresis can avoid or reduce the use of corticosteroids in the management of UC. Large, well-designed clinical trials are necessary to more accurately evaluate the steroid-sparing effects of leukocytapheresis in the management of UC.Active ulcerative colitis (UC) is frequently associated with infiltration of a large number of leukocytes into the bowel mucosa.
