有四项2期研究关于反义ICAM-1抑制剂阿利福生在溃疡性结肠炎中(UC)的应用。包含的患者在入选时,其结肠炎的范围和疾病的严重程度均不相同。来自英国的S. Vegter近日发表论文,该研究调查阿利福生灌肠剂在特定UC患者中的有效性。有效性的分析为:与病变范围为肛缘以上40cm的患者、中或重度患者或同时具有以上特征的患者运用安慰剂或大剂量美沙拉嗪灌肠剂治疗后的短期及长期结果比较。荟萃分析显示,对于活动性UC患者,尤其是中重度远端肠道病变患者,阿利福生是有效的。在这些亚组中,阿利福生的有效性是持久的,显示出缓解疾病的作用。这项分析显示,阿利福生灌肠剂可为中重度远端肠道的活动性UC提供有效的、可能的持久作用。该文在线发表于2013年第3期38卷《营养药理与治疗学》(Alimentary Pharmacology & Therapeutics)杂志上。

研究者对四项2期研究中200名患者进行单病例Meta分析,对夜间行240mg阿利福生灌肠者及其对比者进行评估。患者数据被集中起来进行单数据集分析。使用方差分析评价连续的结果;二分式结果使用Pearson卡方检验或精确概率法进行评估。

结果在使用安慰剂的病变范围为40cm的患者、中重度患者及以上条件均具备的患者中,阿利福生具有更好的有效性。在这些患者组中,美沙拉嗪也显示出短期效果。但在30周后,美沙拉嗪的有效性衰退,而阿利福生有效性明显。
