abstract
Background: Leukocytapheresis (LAP) could be an alternative treatment for steroid-dependent ulcerative
colitis (UC).
Aims: To assess the duration of response at 1 year after this treatment.
Patients and methods: A prospective study in 18 patients with steroid-dependent UC treated with LAP
plus steroids after failure or intolerance to immunomodulators. Clinical and endoscopic (Mayo Clinic
index) examinations were performed at 1 month after the last apheresis and at 12 months. The clinical,
endoscopic remission and the relapse during the 1-year follow-up were evaluated based on standard
parameters.
Results: Induction of remission: clinical remission: 10/18 (55%). Partial response: 4. Endoscopic remission:
9 (50%), always accompanied by clinical remission. A significant correlation was observed between clin-
ical remission and endoscopic remission (r
s
= 0.894; p ≤ 0.001). At 1 year: sustained steroid-free clinical
remission in 9 (50%), all of whom presented initial endoscopic remission. Remission and relapse before 1
year in 17%. A tendency for sustained remission at 1 year was observed when initial endoscopic remission
was achieved.
Conclusions: Initial remission can be maintained at 1 year in half of the patients without the need for
additional steroids. Complete remission and endoscopic mucosal healing is proposed as an objective for
achieving a lasting response.

1. Introduction
Ulcerative colitis (UC) and Crohn’s Disease (CD) are chronic
inflammatory bowel diseases (IBD) which are characterised by
their recurrent nature. Systemic steroids are currently still the
best way of inducing remission in moderate to severe episodes,
although it has been found that 29% of patients required surgery
and 22% developed steroid-dependent UC at 1 year after steroid
treatment [1]. In the latter case, the therapeutic objective should
be a complete withdrawal of steroids in order to avoid their long-
term side-effects [2]. Thiopurine-type immunomodulators and
biological infliximab-based treatments are effective in maintaining
remission in the absence of steroids when conventional treatment
fails [3,4], although a significant number of patients can lose this
response or are intolerant to these treatments [5,6]. Other alter-

native treatments are therefore required that allow remission to
be maintained in the long term and the course of the steroid-
dependent disease to be modified, thereby delaying or preventing
the need for colectomy.
UC activity is associated with an increase in activated granu-
locytes and monocytes-macrophages in peripheral blood and the
colonic mucosa, where they are a major cause of tissue damage
[7]. Indeed, the extent of mucosal infiltration by neutrophils has
been qualitatively linked to the severity of symptoms and the like-
lihood of relapse [8]. Granulocytes and monocytes-macrophages
are therefore potential therapeutic targets for the treatment of IBD
and other autoimmune diseases.
Leukocyte apheresis techniques allow the selective adsorption
of various types of circulating activated leukocytes, which are
replaced by immature, inactive, CD-10-negative leukocytes [9].
Their ability to migrate to, and infiltrate, tissue is thereby greatly
reduced. As well as this mechanism, several studies have detected
an immunomodulatory effect and have suggested other possible
mechanisms of action, such as a reduction in the production of acti-
vated proinflammatory cytokines (IL-1, TNF, IL-6, IL-8) [9,10], an
increase in anti-inflammatory mediators (soluble TNF, HGF and
