Ulcerative colitis (UC) and Crohn's disease (CD), collectively known as inflammatory bowel disease (IBD), afflict an estimated one million Americans and produce symptoms that impair quality of life and ability to function. Progress in IBD management strategies has led to optimized approaches for achieving the two primary clinical goals of therapy: induction and maintenance of remission. Although surgery is indicated to treat refractory disease or specific complications, pharmacotherapy is the cornerstone of IBD management. The efficacy of aminosalicylates for induction of remission in mild to moderate UC and CD is well established, as is their role for maintenance of remission in UC. The sulfa-free mesalamine formulation offers an adverse effect profile similar to that of placebo, enabling the administration of higher, more effective doses. Although corticosteroids provide potent anti-inflammatory effects, their benefits are countermanded by the risk of intolerable and serious adverse effects, and they are ineffective for maintenance therapy. Other agents effective in inducing or maintaining remission are azathioprine, 6-mercaptopurine, infliximab, cyclosporine, methotrexate, and antibiotics. Ongoing clinical trials of experimental therapies will generate new tools for IBD treatment. Currently, a broad range of options allows physicians to tailor treatment to each patient's needs and preferences. Such considerations are essential for maximizing adherence to therapy.
溃疡性结肠炎(UC)和克罗恩病(CD)统称为炎症性肠病(IBD),据估计影响着100万美国人,并产生损害生活质量和功能能力的症状。IBD管理策略的进展已带来优化方法,以实现治疗的两个主要临床目标:诱导缓解和维持缓解。虽然手术用于治疗难治性疾病或特定并发症,但药物治疗是IBD管理的基石。氨基水杨酸类药物在轻至中度UC和CD中诱导缓解的疗效已得到充分证实,其在UC中维持缓解的作用也是如此。无磺胺美沙拉嗪制剂的不良反应谱与安慰剂相似,能够给予更高、更有效的剂量。虽然皮质类固醇具有强大的抗炎作用,但其益处被难以耐受和严重不良反应的风险所抵消,且它们对维持治疗无效。其他有效诱导或维持缓解的药物有硫唑嘌呤、6-巯基嘌呤、英夫利昔单抗、环孢素、甲氨蝶呤和抗生素。正在进行的实验性治疗临床试验将产生IBD治疗的新工具。目前,广泛的选择使医生能够根据每个患者的需求和偏好量身定制治疗方案。这些考虑对于最大限度地提高治疗依从性至关重要。
