Popis: | Background: We aimed to systematically review the efficacy of unfractionated heparin (UFH) or low molecular weight heparins (LMWH) for remission induction in patients with ulcerative colitis (UC). Methods: A literature search to April 2011 was performed to identify all randomized trials studying UFH or LMWH use in patients with UC. The Cochrane Risk of Bias Tool was used to assess study quality. Results: LMWH administered subcutaneously showed no benefit over placebo for any outcome, including clinical remission, and clinical, endoscopic, or histological improvement. High-dose LMWH administered via an extended colon-release tablet demonstrated benefit over placebo for clinical remission (odds ratio [OR] 2.73; 95% confidence interval [CI] 1.32–5.67; P = 0.007), clinical improvement (OR 2.99; 95% CI 1.30–6.87; P = 0.01), and endoscopic improvement (OR 2.25; 95% CI 1.01–5.01; P = 0.05) but not endoscopic remission or histologic improvement. LMWH was not beneficial when added to standard therapy for clinical remission, clinical improvement, endoscopic remission, or endoscopic improvement. One study examining UFH versus corticosteroids for the treatment of severe UC demonstrated the inferiority of UFH for clinical improvement. More patients assigned to UFH had rectal hemorrhage as an adverse event. Conclusions: LMWH administered by extended colon-release tablets may be effective for the treatment of active UC. This benefit needs to be confirmed by further randomized controlled studies. The same benefits were not seen when LMWH was administered subcutaneously at lower doses. There is no evidence to support the use of UFH for the treatment of active UC. (Inflamm Bowel Dis 2011;) |
