PP2-05 Clinical factors associated with relapse of ulcerative colitis after granulocyte-monocyte adsorption
Clinical factors correlated with early relapse of ulcerative colitis (UC) after granulocytemonocyte adsorption (GMA) were investigated. The data from 61 UC patients treated by a
series of 10 sessions of GMA were collected retrospectively. UC was relapsed in 14 patients
(23%) within 24 weeks after GMA. Compared with non-relapse group, relapse group had
significantly higher value of Seo index (SI) evaluated before and after GMA treatment.
Binomial logistic regression analysis showed that SI was significantly correlated with UC
relapse. Relapse rate was significantly different between groups divided according to SI. Seo
index may associated with early relapse of UC.
Pouchitis: a practical guide
A Hillary Steinhart , Ofer Ben-Bassat Frontline Gastroenterol 2013 Jul;4(3):198-204. doi: 10.1136/flgastro-2012-100171. Epub 2013 Nov 12.
Up to 30% of patients with ulcerative colitis (UC) will require surgical management. The established surgical procedure of choice is colectomy with ileal pouch-anal anastomosis (IPAA) for most patients. Patients with UC who have undergone IPAA are prone to develop inflammatory and non-inflammatory complications. Up to 50% of patients can be expected to experience at least one episode of pouchitis, and most of these patients will experience at least one additional acute episode within 2 years. In other cases, pouchitis might follow a relapsing-remitting course or a chronically active course. The specific aetiology of pouchitis is unknown and the optimal means of diagnosis and classification of pouchitis is not completely agreed upon. Diagnosis of pouchitis based on symptoms alone has been shown to be non-specific due to the fact that symptoms can originate from a myriad of aetiologies, not necessarily inflammatory in nature. As a result, the diagnosis of pouchitis should generally be based on the appropriate constellation of symptoms, combined with endoscopic and histological assessment. Due to the frequently relapsing course of pouchitis, and the fact that the aetiology and pathogenesis are not entirely clear, the long-term management can sometimes be challenging. This review outlines the features suggestive of deviation from ‘normal’ pouch function and provides an approach to the optimal use of diagnostic modalities and medical therapies to treat pouchitis in its various forms.
Evidence-based management of ulcerative colitis
D J Gracie 1, A C Ford Minerva Gastroenterol Dietol. 2012 Jun;58(2):87-99.
Ulcerative colitis (UC) is a chronic inflammatory disorder of the gastrointestinal tract, the exact etiology of which remains unknown. The prevalence in the general population is around 0.25%, and the condition represents a considerable financial burden to the health service. The natural history of the condition is one of periods of remission, punctuated by relapses of disease activity. Medical therapy aims to minimise the frequency of these relapses, as well as the need for glucocorticosteroids, which have potentially deleterious effects. In those with acute severe disease, however, glucocorticosteroids are probably effective, as are infliximab and cyclosporine. In those with a mild to moderate flare of disease activity, oral or topical 5-ASAs, or in combination, are more effective than placebo for induction of remission. Doses of oral 5-ASAs in excess of 2g/day appear to lead to higher likelihood of successful remission. Once remission has been achieved, there is evidence to support the use of oral or topical 5-ASAs, and azathioprine to prevent relapse of disease activity. Again, doses of 5-ASA in excess of 2g/day are associated with a lower risk of relapse. Individuals with chronic relapsing and remitting disease activity are difficult to manage, and may require colectomy with ileal pouch anal anastamosis. Granulocyte/monocyte adsorptive apheresis could be of benefit in this setting, but most trials have been conducted in the Far East, so the efficacy in Western UC patients is unclear.
