The efficacy of infliximab has been demonstrated in patients with both acute severe and moderate-severe ulcerative colitis (UC). However, there is a need for 'real-life data' to ensure that conclusions from trial settings are applicable in usual care. We therefore examined the national experience of anti-tumour necrosis factor-α (TNF-α) therapy in UC.
Case notes review of patients with UC who had received compassionate access (CA) anti-TNF-α therapy from prospectively maintained inflammatory bowel disease databases of six Australian adult teaching hospitals.
Patients either received drug for acute severe UC (ASUC) failing steroids (n = 29) or for medically refractory UC (MRUC) (n = 35). In ASUC, the treating physicians judged that anti-TNF-α therapy was successful in 20/29 patients (69%); in these cases, anti-TNF-α was able to be discontinued (after 1-3 infusions in 19/20 responders) as clinical remission was achieved. Consistent with this perceived benefit, only 7/29 (24%) subsequently underwent colectomy during a median follow up of 12 months (interquartile range (IQR) 5-16). Eight of the 35 patients with MRUC (23%) required colectomy during a median follow up of 28 months (IQR 11-43). The majority of these patients (20/35 or 57%) had anti-TNF-α therapy for ≥4 months, whereas, 27/29 (93%) of ASUC patients had CA for ≤3 months.
These data show an excellent overall benefit for anti-TNF-α therapy in both ASUC and MRUC. In particular, only short-duration anti-TNF-α was required in ASUC. These real-life data thus support the clinical trial data and should lead to broader use of this therapy in UC.
英夫利昔单抗在急性重症和中重度溃疡性结肠炎(UC)患者中的疗效已得到证实。然而,需要“真实世界数据”来确保试验环境下得出的结论适用于常规治疗。因此,我们研究了澳大利亚全国范围内抗肿瘤坏死因子-α(TNF-α)治疗UC的经验。
对来自澳大利亚六家成人教学医院前瞻性维护的炎症性肠病数据库中接受同情用药(CA)抗TNF-α治疗的UC患者的病历进行回顾。
患者要么因急性重症UC(ASUC)类固醇治疗失败(n = 29),要么因药物难治性UC(MRUC)(n = 35)接受药物治疗。在ASUC中,治疗医生判断抗TNF-α治疗在20/29例患者(69%)中成功;在这些病例中,由于实现了临床缓解,抗TNF-α能够停药(19/20例缓解者在1 - 3次输注后)。与这种明显的益处一致,在中位随访12个月(四分位间距(IQR)5 - 16)期间,只有7/29例(24%)随后接受了结肠切除术。35例MRUC患者中有8例(23%)在中位随访28个月(IQR 11 - 43)期间需要进行结肠切除术。这些患者中的大多数(20/35或57%)接受抗TNF-α治疗≥4个月,而ASUC患者中有27/29例(93%)接受CA治疗≤3个月。
这些数据显示抗TNF-α治疗在ASUC和MRUC中总体益处显著。特别是,ASUC中仅需要短期抗TNF-α治疗。这些真实世界数据因此支持临床试验数据,并应促使该疗法在UC中得到更广泛的应用。
