Advances in conventional therapy, novel targets and therapeutic goals are the highlights of treatment for ulcerative colitis in the last year. There have also been disappointments. This review summarizes the highs and lows, with an emphasis on strategy as opposed to seeking the newest treatment option.
In conventional therapy, once daily therapy for 5-aminosalicylic acid is generally sufficient. Furthermore, a new 5-aminosalicylic acid (mesalamine MMX) has been released that effectively induces and maintains remission. There have been reappraisals of immunomodulators and further evaluation of (yes, now conventional!) infliximab for ulcerative colitis. Opportunistic infections, long-term outcomes and the burden of disease are being characterized. New therapeutic targets included an antibody against T cells (anti-CD3), but trials on visilizumab for acute severe colitis have been suspended. T-cell costimulation, phosphatidylcholine to promote barrier function, new anti-tumour necrosis factor agents, B-cell (anti-CD20) depletion and complementary therapies represent new therapeutic horizons. International agreement is needed on activity indices, definitions of remission, therapeutic goals (including mucosal healing) and outcomes that matter to patients, so that trials can be compared.
Advances will take time to alter mainstream practice, but 2007-2008 is the year of organized strategies, with European, American and British guidelines on ulcerative colitis published or in press. These should be the platform for better outcomes for patients.
综述目的:传统治疗方法的进展、新靶点及治疗目标是过去一年溃疡性结肠炎治疗的亮点。当然也有令人失望之处。本综述总结了这些成败之处,重点在于策略而非寻求最新的治疗选择。
近期研究结果:在传统治疗方面,5-氨基水杨酸每日一次给药通常就足够了。此外,一种新型5-氨基水杨酸(美沙拉嗪MMX)已上市,它能有效诱导并维持缓解。免疫调节剂得到了重新评估,英夫利昔单抗(现在已算是传统药物了!)用于溃疡性结肠炎也得到了进一步评估。机会性感染、长期疗效及疾病负担正在得到明确。新的治疗靶点包括一种抗T细胞抗体(抗CD3),但针对维西利单抗治疗急性重症结肠炎的试验已暂停。T细胞共刺激、促进屏障功能的磷脂酰胆碱、新型抗肿瘤坏死因子药物、B细胞清除(抗CD20)及辅助治疗代表了新的治疗前景。需要就活动指数、缓解的定义、治疗目标(包括黏膜愈合)及对患者重要的结局达成国际共识,以便对试验进行比较。
总结:进展要改变主流治疗方法尚需时日,但2007至2008年是制定有组织策略的年份,欧洲、美国和英国关于溃疡性结肠炎的指南已发布或即将发布。这些指南应成为让患者获得更好治疗效果的平台。
