ABSTRACT It has been recommended that the treatment of active ulcerative colitis (UC) should be continued until complete healing of endoscopic lesions. However, the evidence supporting this recommendation is scanty. Aims of the present study were to assess the rate of patients with active UC who achieve clinical but not endoscopic remission after treatment with oral plus topical mesalazine and to compare the rate of relapse in patients with clinical/endoscopic remission and those with only clinical remission.
Patients with active mild or moderate UC were eligible. All patients received mesalazine, 4 g/day orally and 2 g/day per rectum for 6 weeks. Those achieving clinical remission underwent colonoscopy: afterwards, all received maintenance treatment with oral mesalazine, 2 g/day orally for 1 year. Clinical remission was defined as normal frequency of bowel movements with formed stools, no abdominal pain, and no blood in the stools. Endoscopic remission was defined as normal-appearing mucosa or only mild redness and/or friability, without either ulcers or erosions.
In all, 81 patients were enrolled. Sixty-one (75%) achieved clinical remission. Endoscopic activity was still present in five (8%). The cumulative rate of relapse at 1 year was 23% in patients with clinical and endoscopic remission and 80% in patients with only clinical remission (P < 0.0001).
Persistence of endoscopic activity is quite infrequent in patients with active UC achieving clinical remission after a 6-week treatment with oral plus topical mesalazine, but is a very strong predictor of early relapse.

    ABSTRACT: Inflammatory bowel diseases (IBD) are chronic and disabling conditions. Accumulating evidence indicates that we need to look beyond clinical symptoms as current therapeutic strategies have not modified the course of IBD. Therapeutic goals for IBD have evolved from a mere control of symptoms to mucosal healing (MH). Achieving deep remission (clinical remission, biomarker remission and MH) might be the only way to alter disease course in IBD patients. In Crohn's disease (CD), deep remission has been recently defined as Crohn's Disease Activity Index <150 and complete MH. In ulcerative colitis (UC), there is no proposed definition of deep remission. It could be defined as clinical and endoscopic remission in UC. These definitions remain to be validated in large prospective studies. In the near future, the concept of deep remission might include transmural healing in CD and histologic healing in UC. Advances in drug development have provided highly effective treatments for IBD, making deep remission a realistic goal. Whether IBD patients may benefit by experiencing a 'deep' remission beyond the control of clinical symptoms, which might ultimately impact on important outcomes such as the need for surgery and the development of disability, needs to be evaluated in future disease modification trials.

    ABSTRACT: Background and Objectives. Mucosal healing (MH) is considered an important therapeutic goal in ulcerative colitis (UC). We evaluate the severity of intestinal inflammation and clarify the relation between MH and long-term outcomes. Methods. The study group comprised 38 patients with UC in clinical remission on total colonoscopy who were followed up for at least 5 years. Clinical remission was defined as a Mayo score of 0 for both stool frequency and rectal bleeding. Colonoscopic findings were evaluated into 4 grades according to the Mayo endoscopic subscore (MES). Results. During clinical remission, the MES was 0 in only 24% of the patients, 1 in 40%, 2 in 26%, and 3 in 10%. Seventy-six percent of the patients thus had active disease on colonoscopy. After initial colonoscopy, the cumulative rate of remission maintenance was 100% in MES 0, 1 in 93%, 2 in 70%, and 3 in 50% at 6 months and 78%, 40%, 10%, and 0%, respectively, at 5 years (P < 0.001). Conclusion. Many patients with UC in clinical remission have active lesions. Patients with a higher MES have a higher rate of recurrence. To improve long-term outcomes, an MES of 0 should be the treatment goal.
