Background The association of intestinal Behçet’s disease (BD) with the risk of hematologic malignancy is still unclear. We aimed to assess the prevalence and determine risk factors of hematologic malignancy in intestinal BD. Methods Using a cohort of patients with intestinal BD between 1997 and 2021, the prevalence and risk factors of hematologic malignancy were analysed by logistic regression analysis at inflammatory bowel disease centre of Severance Hospital, Seoul, Korea. Results Among 780 intestinal BD patients, 23 patients developed hematologic malignancy. Myelodysplastic syndrome (MDS) (n=12) was the most common hematologic malignancy, followed by aplastic anemia (AA) (n=7), leukemia (n=2), and lymphoma (n=2). Eight patients had developed hematologic malignancy before their intestinal BD diagnosis and 15 patients developed hematologic malignancy after their intestinal BD diagnosis. Of the 772 patients without previous hematologic malignancy, patients smoking history (p-value 0.019, odds ratio [OR] 49.513, 95% confidence interval [CI] 1.925-1273.4), history of at least one emergency room (ER) visit (p-value 0.025, OR 26.360, CI 1.501-462.92), and albumin lower than 3.3g/dL (p-value 0.046, OR 603.013, CI 0.108-328191.23) at diagnosis were positively associated with subsequent hematologic malignancy. Body mass index (BMI) (p-value 0.030, OR 0.569, CI 0.342-0.947) was negatively associated with hematologic malignancy. Conclusion The physicians who care for intestinal BD patients with risk factors should be aware and provide careful monitoring of the elevated risk of hematologic malignancy.
背景 肠白塞氏病(BD)与血液系统恶性肿瘤风险的关系尚不清楚。我们旨在评估肠道白塞氏病的患病率并确定血液系统恶性肿瘤的风险因素。方法 韩国首尔 Severance 医院炎症性肠病中心利用 1997 年至 2021 年间的肠道 BD 患者队列,通过逻辑回归分析法对血液系统恶性肿瘤的患病率和风险因素进行了分析。结果 在 780 名肠道 BD 患者中,有 23 人罹患血液系统恶性肿瘤。骨髓增生异常综合征(MDS)(12 人)是最常见的血液系统恶性肿瘤,其次是再生障碍性贫血(AA)(7 人)、白血病(2 人)和淋巴瘤(2 人)。8 名患者在确诊肠道 BD 之前就已罹患血液系统恶性肿瘤,15 名患者在确诊肠道 BD 之后罹患血液系统恶性肿瘤。在 772 例既往未患血液系统恶性肿瘤的患者中,吸烟史(P 值 0.019,几率比 [OR] 49.513,95% 置信区间 [CI]1.925-1273.4)、至少一次急诊室就诊史(P 值 0.025,OR 26.360,CI 1.501-462.92)、诊断时白蛋白低于 3.3g/dL(p 值 0.046,OR 603.013,CI 0.108-328191.23)与随后的血液系统恶性肿瘤呈正相关。体重指数(BMI)(p-value 0.030,OR 0.569,CI 0.342-0.947)与血液恶性肿瘤呈负相关。结论 为具有危险因素的肠道 BD 患者提供护理的医生应了解血液恶性肿瘤风险升高的情况,并进行仔细监测。

Background It is known that the mucosal-associated invariant T (MAIT) cells are the innate-like T cells that are restricted by the major histocompatibility complex-related molecule 1 (MR1), and that these cells express a semi-invariant T cell receptor. We have previously reported that the activation status of the circulating MAIT cells in patients with Ulcerative Colitis (UC) is associated with disease activity, and these cells infiltrate the inflamed colonic mucosa. These findings imply that MAIT cells are involved in the pathogenesis of Inflammatory Bowel Disease (IBD). However, the role of MAIT cells in the setting of IBD has not been revealed. Therefore, we investigated the role of MAIT cells in an animal model of UC. Methods To this end, we utilized MR1 deficient mice (MR1-/-), which lack MAIT cells, and isobutyl 6-formyl pterin (i6-FP), which is a synthetic antagonistic MR1 ligand. MR1-/- on the C57BL/6 background, their littermate wild-type controls, and C57BL/6 mice were sensitized by rectal administration of oxazolone to induce colitis. These were then administered an oral i6-FP. Splenocytes (SPL) and colonic lamina propria lymphocytes (LPL) were isolated from mice receiving i6-FP to measure cytokine production. MR1-/-, i6-FP-treated mice and their controls were orally administered FITC-dextran to analyze intestinal permeability. The peripheral blood mononuclear cells (PBMC) from the patients with UC were also isolated to study the effect of i6-FP on cytokine production by MAIT cells. Results MR1 deficiency or i6-FP treatment resulted in reduced severity of oxazolone-induced colitis. Mice treated with i6-FP resulted in reduced MAIT cell production of pro-inflammatory cytokines such as IFN-g and TNF in both SPL and colonic LPL. Similar results were also observed in PBMC isolated from the patients with UC when incubated with i6-FP. Although MR1 deficiency resulted in increased intestinal permeability, i6-FP administration did not affect gut integrity in mice. Conclusion The current studies indicate that MAIT cells have a pathogenic role in colitis and suppressing activation of these cells may reduce the severity of colitis without affecting gut integrity. Thus, MAIT cells may be potential therapeutic targets for IBD including UC.
背景众所周知,粘膜相关不变型T细胞(MAIT)是先天性类T细胞,受到主要组织相容性复合体相关分子1(MR1)的限制,这些细胞表达一种半不变型T细胞受体。我们以前曾报道过,溃疡性结肠炎(UC)患者循环中的 MAIT 细胞的活化状态与疾病活动有关,而且这些细胞会浸润发炎的结肠粘膜。这些发现意味着 MAIT 细胞参与了炎症性肠病(IBD)的发病机制。然而,MAIT 细胞在 IBD 中的作用尚未被揭示。因此,我们研究了 MAIT 细胞在 UC 动物模型中的作用。为此,我们利用了缺乏 MAIT 细胞的 MR1 缺失小鼠(MR1-/-)和异丁基 6-醛基蝶呤(i6-FP),后者是一种合成的 MR1 拮抗配体。C57BL/6背景的MR1-/-小鼠、它们的同窝野生型对照组和C57BL/6小鼠通过直肠给药噁唑酮诱发结肠炎。然后给这些小鼠口服 i6-FP。从接受 i6-FP 的小鼠体内分离出脾细胞(SPL)和结肠固有层淋巴细胞(LPL),以测定细胞因子的产生。给接受 i6-FP 的 MR1-/- 小鼠及其对照组口服 FITC 右旋糖酐以分析肠道通透性。还分离了 UC 患者的外周血单核细胞 (PBMC),以研究 i6-FP 对 MAIT 细胞产生细胞因子的影响。结果 MR1 缺乏或 i6-FP 治疗可降低恶唑隆诱导的结肠炎的严重程度。用 i6-FP 处理小鼠后,MAIT 细胞在 SPL 和结肠 LPL 中产生的促炎细胞因子(如 IFN-g 和 TNF)减少。用 i6-FP 培养从 UC 患者体内分离出的 PBMC 也观察到了类似的结果。虽然 MR1 缺乏会导致肠道通透性增加,但服用 i6-FP 不会影响小鼠肠道的完整性。结论 目前的研究表明,MAIT 细胞在结肠炎中具有致病作用,抑制这些细胞的活化可减轻结肠炎的严重程度,而不会影响肠道完整性。因此,MAIT 细胞可能是包括 UC 在内的 IBD 的潜在治疗靶点。

Background Studies from mainly before the wide use of targeted therapies and guidelines for thromboprophylaxis indicate that patients with inflammatory bowel disease (IBD) are at a doubled risk of venous thromboembolism (VTE). We studied the risk of VTE in a modern-day cohort of patients with IBD, overall and in subgroups of disease characteristics. Methods Using Swedish healthcare registers, we identified a nationwide population-based cohort of 55,252 patients with incident IBD between 2007 and 2021 with a median follow-up time of 6.5 years. Patients were matched by age, sex, calendar year and county of residence with up to ten reference individuals from the general population (N=536,067). The primary outcome was VTE, including pulmonary embolism and deep vein thrombosis. Incidence rates per 1,000 person-years and hazard ratios (HR) were calculated for IBD in general and according to disease subtype, sex, age and disease characteristics at diagnosis. HRs stratified by matching variables (model 1) and additionally adjusted for comorbidities and socioeconomic factors (model 2) were estimated by using Cox regression. Results The incidence rate of VTE among patients with IBD was 5.03 per 1,000 person-years compared with 2.34 per 1,000 person-years among reference individuals (Table 1). This corresponded to a doubled incidence of VTE (HR=2.18, 95% confidence interval (CI)=2.07-2.29, model 1). Adjusting further for covariates in model 2 had only minor effects on the HR. The HR was consistent across IBD subtypes and sex. The relative risk was higher for those with younger age (18-39 years) at IBD diagnosis (HR 2.52, 95% CI: 2.22-2.83) with a risk difference of 1.25 per 1,000 person-years. The IR, 10.64 per 1,000 person-years, and risk difference, 5.42 per 1,000 person-years, was the highest for those with elderly onset (≥60 years) IBD. There was a stronger association for those with extensive ulcerative colitis (E3), primary sclerosing cholangitis, extraintestinal manifestations and perianal disease. HRs for VTE were persistently elevated across follow-up time, but was higher during the first year of follow-up (Figure 1). Conclusion The risk of VTE was doubled in these modern-day data and remained elevated across follow-up time. Disease characteristics associated with higher inflammatory burden at diagnosis and older age are markers of increased risk. This underscores the importance of continuous vigilance and individual assessment of risk factors for VTE in patients with IBD.
背景 研究表明,炎症性肠病(IBD)患者罹患静脉血栓栓塞症(VTE)的风险加倍。我们研究了现代 IBD 患者队列中的 VTE 风险,包括总体风险和疾病特征亚组风险。方法 我们利用瑞典医疗保健登记册,在全国范围内确定了一个基于人群的队列,该队列包含 55,252 名在 2007 年至 2021 年间发病的 IBD 患者,中位随访时间为 6.5 年。患者按年龄、性别、日历年和居住地县与多达 10 个来自普通人群的参照个体(N=536,067)进行配对。主要结果是VTE,包括肺栓塞和深静脉血栓。根据疾病亚型、性别、年龄和诊断时的疾病特征,计算了一般 IBD 患者的每千人年发病率和危险比 (HR)。采用 Cox 回归法估算了按匹配变量分层(模型 1)并根据合并症和社会经济因素进行额外调整(模型 2)后的危险比。结果 IBD 患者的 VTE 发病率为每千人年 5.03 例,而参照个体的发病率为每千人年 2.34 例(表 1)。这相当于VTE发病率翻了一番(模型1,HR=2.18,95%置信区间(CI)=2.07-2.29)。在模型2中进一步调整协变量对HR的影响很小。不同IBD亚型和性别的HR是一致的。诊断 IBD 时年龄较小(18-39 岁)的人群相对风险更高(HR 2.52,95% CI:2.22-2.83),每千人年的风险差异为 1.25。老年(≥60 岁)IBD 患者的IR(每千人年 10.64 例)和风险差异(每千人年 5.42 例)最高。与广泛性溃疡性结肠炎(E3)、原发性硬化性胆管炎、肠道外表现和肛周疾病相关的风险更高。在整个随访期间,VTE 的 HR 值持续升高,但在随访的第一年更高(图 1)。结论 在这些现代数据中,发生 VTE 的风险增加了一倍,并且在整个随访期间持续升高。与诊断时炎症负担较重和年龄较大相关的疾病特征是风险增加的标志。这强调了对 IBD 患者 VTE 风险因素持续警惕和个体评估的重要性。

Background As an objective endpoint in IBD Disease-Modification Trials, measures of disability and health-related quality of life have been proposed. IBD-DISK is an easy-to-use, and self-administered analogic visual tool designed for assessing disability. However, successful dissemination of this tool will require a cultural adaptation and translation process. To date, the IBD-Disk has not been validated in Italian clinical practice. Hence, we aimed to validate the IBD-Disk in an Italian population-based cohort according to the COSMIN recommendations. Methods The IBD-Disk italian translation and validation study was a cross-sectional multicentre study conducted in 8 Italian IBD referral centres. After forward-backward translation into Italian, patients were consecutively recruited from February 2023 to October 2023. Patients completed the following questionnaires: IBD-Disk (at baseline, T0, and after seven days, T1) and IBD-Disability Index (IBD-DI) for disability, IBDQ-32, and SF-36 for quality of life. Validation included assessment of validity, reproducibility, internal consistency. We further investigated the correlation between IBD-Disk and IBD activity and clinical factors associated with IBD-Disk. Results At baseline, 513 patients (237,46.2% CD; 276,53.8% UC) completed the IBD-Disk[Table.1]. Internal consistency was excellent with a Cronbach’s α of 0.93. The intraclass correlation coefficient (ICC) was 0.94 for test-retest (T0 and T1) (p< 0.001). To evaluate construct validity, the IBD-Disk was compared with the IBD-DI, revealing a significant positive correlation (r = 0.70; p < 0.001). Furthermore, it exhibited a positive correlation with both IBDQ-32(r=0.82, p< 0.001) and SF-36(r=0.093, p= 0.035). The overall IBD-Disk median score was 32(12-52), with 219(42.7%) reporting moderate-to-severe disability (IBD-DISK ≥ 40). The IBD-Disk score was significantly higher in patients with active CD disease based on HBI ≥ 5 compared to patients with inactive disease(p < 0.001). Similarly, for UC, patients with active disease, measured with a partial Mayo score ≥2, showed a higher IBD-DISK score than those in clinical remission[Fig.1]. Additionally, moderate-to-severe disability significantly increased in female [OR =2.83; 95% CI(1,97-4,07)] and in patients with active extraintestinal manifestations [OR = 1,71; 95%CI(1,23-2,81) p=0.04]. Conclusion This study validated the IBD-Disk in a large cohort of Italian IBD patients, demonstrating that it is a valid, reliable and responsive tool for quantifying disability. This validation enables the broad implementation of IBD-DISK across Italy, facilitating its integration into the daily clinical management of IBD patients.
背景 作为 IBD 疾病调整试验的客观终点,有人提出了残疾和健康相关生活质量的测量方法。IBD-DISK 是一种易于使用的自测类比视觉工具,用于评估残疾情况。然而,这一工具的成功推广需要一个文化适应和翻译过程。迄今为止,IBD-DISK 尚未在意大利临床实践中得到验证。因此,我们旨在根据 COSMIN 的建议,在意大利人群中验证 IBD-Disk。方法 IBD-Disk意大利语翻译和验证研究是一项横断面多中心研究,在意大利8个IBD转诊中心进行。在前后翻译成意大利语后,从 2023 年 2 月至 2023 年 10 月连续招募患者。患者填写了以下问卷:IBD-Disk(基线时,T0;七天后,T1)和IBD-Disability Index (IBD-DI)(残疾)、IBDQ-32和SF-36(生活质量)。验证包括有效性、再现性和内部一致性评估。我们进一步研究了 IBD-Disk 与 IBD 活动之间的相关性以及与 IBD-Disk 相关的临床因素。结果 基线时,513 名患者(237 人,46.2% 为 CD;276 人,53.8% 为 UC)完成了 IBD-Disk[表 1]。内部一致性极佳,Cronbach's α 为 0.93。测试-重测(T0 和 T1)的类内相关系数(ICC)为 0.94(p< 0.001)。为了评估建构效度,IBD-Disk 与 IBD-DI 进行了比较,结果显示两者之间存在显著的正相关(r = 0.70; p < 0.001)。此外,它与 IBDQ-32(r=0.82,p< 0.001)和 SF-36(r=0.093,p= 0.035)均呈正相关。总体 IBD-Disk 中位数为 32(12-52)分,219 人(42.7%)报告中度至重度残疾(IBD-DISK ≥ 40)。与非活动性疾病患者相比,基于 HBI ≥ 5 的活动性 CD 患者的 IBD-Disk 评分明显更高(p &pamp;lt;0.001)。同样,对于 UC 患者来说,以部分梅奥评分≥2 为衡量标准的活动性疾病患者的 IBD-DISK 评分也高于临床缓解期患者[图 1]。此外,女性[OR=2.83; 95%CI(1,97-4,07)] 和有活动性肠外表现的患者[OR=1,71; 95%CI(1,23-2,81) p=0.04]的中度至重度残疾显著增加。结论 本研究在一大批意大利 IBD 患者中验证了 IBD-Disk,证明它是一种有效、可靠且反应灵敏的残疾量化工具。通过验证,IBD-DISK 可在意大利全国范围内广泛应用,促进其融入 IBD 患者的日常临床管理中。

Patients completed the following questionnaires: IBD-Disk (at baseline, T0, and after seven days, T1) and IBD-Disability Index (IBD-DI) for disability, IBDQ-32, and SF-36 for quality of life. Validation included assessment of validity, reproducibility, internal consistency. We further investigated the correlation between IBD-Disk and IBD activity and clinical factors associated with IBD-Disk. Results At baseline, 513 patients (237,46.2% CD; 276,53.8% UC) completed the IBD-Disk[Table.1]. Internal consistency was excellent with a Cronbach’s α of 0.93. The intraclass correlation coefficient (ICC) was 0.94 for test-retest (T0 and T1) (p< 0.001). To evaluate construct validity, the IBD-Disk was compared with the IBD-DI, revealing a significant positive correlation (r = 0.70; p < 0.001). Furthermore, it exhibited a positive correlation with both IBDQ-32(r=0.82, p< 0.001) and SF-36(r=0.093, p= 0.035). The overall IBD-Disk median score was 32(12-52), with 219(42.7%) reporting moderate-to-severe disability (IBD-DISK ≥ 40). The IBD-Disk score was significantly higher in patients with active CD disease based on HBI ≥ 5 compared to patients with inactive disease(p < 0.001). Similarly, for UC, patients with active disease, measured with a partial Mayo score ≥2, showed a higher IBD-DISK score than those in clinical remission[Fig.1]. Additionally, moderate-to-severe disability significantly increased in female [OR =2.83; 95% CI(1,97-4,07)] and in patients with active extraintestinal manifestations [OR = 1,71; 95%CI(1,23-2,81) p=0.04]. Conclusion This study validated the IBD-Disk in a large cohort of Italian IBD patients, demonstrating that it is a valid, reliable and responsive tool for quantifying disability. This validation enables the broad implementation of IBD-DISK across Italy, facilitating its integration into the daily clinical management of IBD patients.","PeriodicalId":15453,"journal":{"name":"Journal of Crohn's and Colitis","volume":"34 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139559270","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Background Complex perianal fistulas are a serious complication in patients with Crohn’s disease (CD). Darvadstrocel (DVS), a suspension of expanded adult allogeneic adipose-derived mesenchymal stem cells, is approved in Europe and Japan for treatment of complex Crohn’s perianal fistulas (CPF). The global ADMIRE-CD II phase 3 randomized double-blind placebo-controlled study evaluated the efficacy and safety of DVS for treatment of complex CPF. Methods Patients aged 18–75 years with clinically controlled, inactive or mildly active CD and complex CPF (≤2 internal openings [IO] and ≤3 external openings [EOs]) who had an inadequate, or a loss of response to immunosuppressive agents or biologics were included. Patients were randomized 1:1 to receive a local injection of DVS as a single dose (120 x 106 cells/24 mL) or placebo. In all patients, fistula preconditioning included vigorous curettage and seton placement 2–3 weeks before treatment, and seton removal, a further curettage and closure of IOs immediately before treatment. The primary endpoint was combined remission (closure of all treated EOs that were draining at baseline, despite gentle finger compression, and absence of collections >2 cm confirmed by MRI) at 24 weeks. Secondary endpoints included combined remission at 52 weeks, clinical remission (closure of all treated EOs without MRI confirmation) at 24 and 52 weeks, and time to clinical remission at 24 weeks. Safety was monitored up to 52 weeks. Results From 19 Oct 2017 to 26 Jul 2023, 568 patients received DVS (n = 283) or placebo (n = 285) with fistula preconditioning; 56.3% of patients enrolled in Europe and Israel, and 43.7% in North America. Mean (SD) age, sex and race were similar in the DVS and placebo arms (38.4 [11.9] vs 37.7 [10.8] years; 42.8% vs 45.6% female; 85.9% vs 89.1% White). Combined remission rates at 24 weeks did not statistically differ between treatments (48.8% DVS vs 46.3% placebo) and there were no differences in secondary endpoints (Table 1; Figure 1). Based on health authority guidelines, post hoc analyses of patients randomized before COVID-19 (11 March 2020; n = 141 DVS, n = 143 placebo) were performed: combined remission rates at 24 weeks were 46.8% (DVS) and 38.5% (placebo). The safety profile for DVS was consistent with prior studies with no new safety signals (Table 1). Conclusion The efficacy outcomes assessed did not statistically differ between DVS and placebo, and the placebo response rate (with fistula preconditioning) was higher than expected. Post hoc analyses revealed lower placebo response rates in patients randomized before COVID-19 (similar to the pivotal ADMIRE CD I study) than the overall placebo arm. DVS was well tolerated.
背景复杂性肛周瘘是克罗恩病(CD)患者的一种严重并发症。Darvadstrocel(DVS)是一种扩增的成人异体脂肪间充质干细胞悬浮液,已在欧洲和日本获准用于治疗复杂性克罗恩病肛周瘘。全球 ADMIRE-CD II 3 期随机双盲安慰剂对照研究评估了 DVS 治疗复杂性 CPF 的疗效和安全性。方法 纳入年龄为 18-75 岁、临床控制的非活动性或轻度活动性 CD 和复杂 CPF(≤2 个内开口 [IO] 和≤3 个外开口 [EO])患者,这些患者对免疫抑制剂或生物制剂反应不足或失去反应。患者按 1:1 随机分配接受单剂量局部注射 DVS(120 x 106 cells/24 mL)或安慰剂。在所有患者中,瘘管预处理包括在治疗前2-3周进行剧烈刮宫和放置套管,以及在治疗前立即移除套管、进一步刮宫和关闭IO。主要终点是24周时的综合缓解(所有治疗后的瘘管在基线时均有引流,尽管手指轻轻按压,瘘管仍然闭合,并且经核磁共振成像确认没有>2厘米的积液)。次要终点包括:52周时的综合缓解、24周和52周时的临床缓解(所有治疗过的EO在未经核磁共振成像确认的情况下均已闭合)以及24周时的临床缓解时间。安全性监测持续到 52 周。结果 从2017年10月19日至2023年7月26日,568名患者接受了瘘管预处理的DVS(n = 283)或安慰剂(n = 285)治疗;56.3%的患者在欧洲和以色列入组,43.7%的患者在北美入组。DVS治疗组和安慰剂治疗组的平均(标清)年龄、性别和种族相似(38.4 [11.9] 岁 vs 37.7 [10.8]岁;42.8% vs 45.6%为女性;85.9% vs 89.1%为白人)。24周的综合缓解率在统计学上没有差异(DVS为48.8%,安慰剂为46.3%),次要终点也没有差异(表1;图1)。根据卫生部门的指导方针,对在COVID-19(2020年3月11日;n = 141 DVS,n = 143安慰剂)之前随机接受治疗的患者进行了事后分析:24周时的综合缓解率分别为46.8%(DVS)和38.5%(安慰剂)。DVS的安全性与之前的研究一致,没有出现新的安全信号(表1)。结论 DVS 和安慰剂的疗效评估结果没有统计学差异,安慰剂应答率(瘘管预处理)高于预期。事后分析显示,COVID-19(类似于关键的 ADMIRE CD I 研究)之前随机分组的患者的安慰剂应答率低于整个安慰剂组。DVS 的耐受性良好。

Background Upadacitinib is a selective Janus kinase inhibitor that has recently been approved in England for the treatment of ulcerative colitis (UC) and Crohn’s disease (CD) though real-world data is lacking. Furthermore, there is very limited information available on patient reported experiences of treatment with a small molecule compared with biological therapies. The object of this study was to provide real-world data on the efficacy of upadacitinib in the treatment of IBD in conjugation with collecting specific patient-reported feedback on acceptability and experience of treatment with upadacitinib. Methods We prospectively collected data on all IBD patients treated with upadacitinib between November 2022 and November 2023 in a large NHS Trust serving approximately 1% of the population of England. The primary objective was to assess patient response to induction at 8 weeks (UC) and 12 weeks (CD). Demographic details, biochemical markers (faecal calprotectin and CRP) and disease activity scores were recorded. We also undertook a bespoke anonymised electronic survey to assess the patient experience and views on treatment with upadacitinib in comparison to previous treatments. Results Forty-two patients were included in the study (34 UC/8 CD). The average age was 41 (range 18-76) and 27 (64%) were male. 11/34 UC patients were biologic naïve. All CD patients were biologic experienced with the majority exposed to an anti-TNF, vedolizumab and ustekinumab. Overall, 34/40 (85%) patients responded to induction treatment based on disease activity scores (27 UC, 7CD), with 68% (22 UC, 5 CD) in remission. Data was missing for two patients. Response rates were similar between biologic naïve and biologic exposed patients (82% and 86% respectively). In the UC cohort, mean calprotectin at baseline improved from 1718ug/g (range 8-6000ug/g) to 311ug/g (4-3014ug/g). In the CD cohort, mean calprotectin improved from 1719ug/g (115-5874ug/g) to 314ug/g (4-917ug/g). 3/42 (7%) of patients discontinued upadacitinib due to disease progression with the remaining 93% continuing treatment. Our patient survey results revealed very high satisfaction with treatment (85%), with the vast majority preferring treatment with upadacitinib to their previous biological therapy. Conclusion In this real-world study, induction therapy with upadacitinib was well tolerated and demonstrated good efficacy with excellent response and remission rates in a mixed patient cohort that included many with highly refractory disease. No unexpected safety signals were seen. The patient experience was overwhelmingly positive. If this data is replicated in larger studies there is an increasingly strong rationale for introducing upadacitinib earlier in the sequencing of advanced therapies.
背景 乌帕他替尼是一种选择性 Janus 激酶抑制剂,最近在英国获准用于治疗溃疡性结肠炎(UC)和克罗恩病(CD),但缺乏实际数据。此外,与生物疗法相比,患者报告的小分子药物治疗经验方面的信息非常有限。本研究旨在提供有关达帕替尼治疗 IBD 疗效的真实世界数据,同时收集患者报告的有关达帕替尼治疗的可接受性和体验的具体反馈信息。方法 我们前瞻性地收集了2022年11月至2023年11月期间在一家大型NHS信托机构接受奥达帕替尼治疗的所有IBD患者的数据,该信托机构为英格兰约1%的人口提供服务。主要目的是评估患者在8周(UC)和12周(CD)时对诱导治疗的反应。我们记录了详细的人口统计学资料、生化指标(粪便钙蛋白和 CRP)和疾病活动评分。我们还进行了一项定制的匿名电子调查,以评估患者的治疗体验和对达达替尼治疗的看法,并与之前的治疗方法进行比较。结果 42 名患者参与了研究(34 名 UC/8 名 CD)。平均年龄为41岁(18-76岁不等),男性27人(64%)。11/34名UC患者是生物制剂新手。所有 CD 患者都有过生物制剂治疗经验,其中大多数都接触过抗 TNF、维多珠单抗和乌司替尼。总体而言,根据疾病活动评分,34/40(85%)名患者对诱导治疗做出了反应(27 名 UC 患者,7 名 CD 患者),68%(22 名 UC 患者,5 名 CD 患者)的病情得到缓解。有两名患者的数据缺失。未接受生物制剂治疗的患者和接受生物制剂治疗的患者的应答率相似(分别为82%和86%)。在 UC 组群中,基线时的平均钙蛋白从 1718ug/g(范围 8-6000ug/g)降至 311ug/g(4-3014ug/g)。在 CD 组中,平均钙蛋白从 1719ug/g (115-5874ug/g) 降至 314ug/g (4-917ug/g)。3/42(7%)的患者因疾病进展而中止了达达替尼治疗,其余 93% 的患者继续接受治疗。我们对患者的调查结果显示,他们对治疗的满意度非常高(85%),绝大多数患者更愿意接受达达替尼治疗,而不是之前的生物疗法。结论 在这项真实世界的研究中,奥达替尼诱导治疗的耐受性良好,在包括许多高度难治性疾病患者在内的混合患者群中显示出良好的疗效和极高的应答率和缓解率。没有出现意外的安全性信号。患者的体验非常积极。如果这一数据能在更大规模的研究中得到验证,那么在晚期疗法的排序中更早引入奥达帕替尼的理由就会越来越充分。

Background Morphological and functional cardiac involvement is rarely seen in inflammatory bowel disease (IBD) patients but there is evidence that IBD patients have an increased risk of cardiovascular events despite the lower prevalence of traditional cardiovascular (CV) risk factors when compared to the general population. Our systematic review and meta-analysis examined the relationship between IBD and cardiac function, namely incidence of heart failure (HF) and clinical and subclinical echocardiographic changes. Methods Two medical databases, PubMed and Scopus, were systematically searched up to September 2022 to identify all studies reporting heart failure and/or echocardiographic changes in IBD patients. Results We identified 1287 original papers and included 18 in our qualitative analysis. Through analysis of echocardiographic data, we found subtle systolic and diastolic changes in IBD patients. We also found higher vascular dysfunction with increased aortic stiffness, coronary microvascular dysfunction resulting in worse cardiovascular outcomes. This group had an increased risk for HF hospitalizations compared with general population. We have also performed a meta-analysis with 9 studies which included echocardiographic data. In the IBD population we found reduced E/A ratio (Std. MD -0.51, 95% CI: -1.00 to -0.02, p = 0.04, I2 = 87%, p<0.0001), higher values of E/E’ ratio (Std. MD 1.46, 95% CI: 0.86 to 2.07, p<0.00001, I2 = 80%, p=0.02). We evaluated left ventricular function using longitudinal global strain which was decreased in IBD patients (Std. MD 0.66, 95% CI: 0.48 to 0.84, p<0.00001, I2 = 0%, p= 0.55). Overall IBD patients had increased LA diameter (Std. MD 0.06, 95% CI: 0.12 to 0.24, p = 0.50, I2 = 20%), and an increased LA area (Std. MD 0.03, 95% CI: 0.24 to 0.29, p = 0.85, I2 = 0%), but no statistical significance was not reached. A significant increase in inter-atrial and right intra-atrial conduction delay was observed in IBD patients (Std. MD 0.88, 95% CI: 0.45 to 1.31, p<0.0001, I2 = 42%; Std. MD 0.9, 95% CI: 0.57 to 1.22, p < 0.00001, I2 = 0%, respectively). We found no significant bias in our analysis using CASP checklist. Conclusion There is significant evidence to conclude that the IBD population has increased risk for LV and atrial dysfunction, vascular changes, arrhythmias, and heart failure hospitalization. Screening with sensitive imaging like speckle tracking echocardiography could identify early subclinical changes. IBD is in fact a cardiovascular risk factor and tight inflammation control may reduce the risk.
背景 炎症性肠病(IBD)患者很少出现形态学和功能性心脏受累,但有证据表明,尽管传统心血管(CV)风险因素的发生率低于普通人群,但 IBD 患者发生心血管事件的风险却增加了。我们的系统综述和荟萃分析研究了 IBD 与心脏功能之间的关系,即心力衰竭(HF)的发病率以及临床和亚临床超声心动图变化。方法 对截至 2022 年 9 月的两个医学数据库(PubMed 和 Scopus)进行了系统检索,以确定所有报道 IBD 患者心力衰竭和/或超声心动图变化的研究。结果 我们发现了1287篇原创论文,并将18篇纳入了定性分析。通过分析超声心动图数据,我们发现 IBD 患者的收缩压和舒张压发生了微妙变化。我们还发现,主动脉僵硬度增加、冠状动脉微血管功能障碍会导致更严重的心血管后果。与普通人群相比,该群体的心房颤动住院风险更高。我们还对包含超声心动图数据的 9 项研究进行了荟萃分析。在IBD人群中,我们发现E/A比值降低(Std. MD -0.51, 95% CI: -1.00 to -0.02, p = 0.04, I2 = 87%, p<0.0001),E/E'比值升高(Std. MD 1.46, 95% CI: 0.86 to 2.07, p<0.00001, I2 = 80%, p=0.02)。我们使用纵向整体应变对左心室功能进行了评估,发现IBD患者的左心室功能有所下降(Std. MD 0.66, 95% CI: 0.48 to 0.84, p<0.00001, I2 = 0%, p=0.55)。总体而言,IBD 患者的 LA 直径增大(标准 MD 0.06,95% CI:0.12 至 0.24,p=0.50,I2 = 20%),LA 面积增大(标准 MD 0.03,95% CI:0.24 至 0.29,p=0.85,I2 = 0%),但未达到统计学意义。在 IBD 患者中观察到心房间传导延迟和右心房内传导延迟明显增加(分别为标准 MD 0.88,95% CI:0.45 至 1.31,p<0.0001,I2 = 42%;标准 MD 0.9,95% CI:0.57 至 1.22,p<0.00001,I2 = 0%)。我们在使用 CASP 核对表进行分析时未发现明显偏差。结论 有大量证据表明,IBD 患者左心室和心房功能障碍、血管病变、心律失常和心力衰竭住院风险增加。通过斑点追踪超声心动图等敏感成像技术进行筛查,可以发现早期亚临床病变。事实上,IBD 是心血管风险因素之一,严格控制炎症可降低风险。

MD 0.66, 95% CI: 0.48 to 0.84, p<0.00001, I2 = 0%, p= 0.55). Overall IBD patients had increased LA diameter (Std. MD 0.06, 95% CI: 0.12 to 0.24, p = 0.50, I2 = 20%), and an increased LA area (Std. MD 0.03, 95% CI: 0.24 to 0.29, p = 0.85, I2 = 0%), but no statistical significance was not reached. A significant increase in inter-atrial and right intra-atrial conduction delay was observed in IBD patients (Std. MD 0.88, 95% CI: 0.45 to 1.31, p<0.0001, I2 = 42%; Std. MD 0.9, 95% CI: 0.57 to 1.22, p < 0.00001, I2 = 0%, respectively). We found no significant bias in our analysis using CASP checklist. Conclusion There is significant evidence to conclude that the IBD population has increased risk for LV and atrial dysfunction, vascular changes, arrhythmias, and heart failure hospitalization. Screening with sensitive imaging like speckle tracking echocardiography could identify early subclinical changes. IBD is in fact a cardiovascular risk factor and tight inflammation control may reduce the risk.","PeriodicalId":15453,"journal":{"name":"Journal of Crohn's and Colitis","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139559384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Background Crohn's disease (CD) presents differences in genetics, inflammatory components, and microbiota depending on its location. Therapy efficacy may be linked to disease location, but existing research has yielded conflicting results. This study aims to investigate the impact of CD location on first-line biologic therapy requirement and persistence and the risk of intestinal resections. Methods CD patients included in the prospectively maintained ENEIDA registry between January 2005 and May 2023 were considered for the study. Demographics, disease phenotype and location, complications, the utilization of biologic therapies, and intestinal surgeries were analyzed. Cox proportional hazards and Kaplan-Meier methods were used for the analysis of biologic requirement and persistence and risk of surgery. Results A cohort of 17,508 patients was included, with a median follow-up period of 6 years (IQR 2-10 years). The most common disease locations were ileal (43.3%) and ileocolonic (39%), with lower frequency for colonic (16.4%) and upper-gastrointestinal disease (1.2%). A first biologic was used in 54.5% of patients (n=9,543), with a higher 5-year requirement in ileocolonic disease compared to ileal and colonic disease (60.1% vs 53% vs 49.9%, p<0.001). Ileal disease presented the lowest 5-year persistence rate compared to ileocolonic and colonic location (39% vs 41.6% vs 45.1%, p=0.004). Ileal location (aHR 1.084, 95%CI 1.006-1.167), female sex (adjusted Hazard Ratio [aHR] 1.173, 95%CI 1.096-1.254), extraintestinal manifestations (aHR 1.163, 95%CI 1.080-1.251), a history of abdominal surgery (aHR 1.539, 95%CI 1.426-1.661) were independent predictors of drug discontinuation. The cumulative need for intestinal resections was 25.8% (n=4,512), with ileal disease showing the highest hazard for 5-year surgery compared to ileo-colonic and colonic location (19.5% vs 17.8 vs 8.3%, p<0.001). Ileal disease (aHR 1.194, 95%CI 1.101-1.295), stricturing (aHR 2.575, 95%CI 2.378-2.787) and penetrating phenotypes (aHR 2.485, 95%CI 2.261-2.734), a history of biologic therapy (aHR 1.386, 95%CI 1.262-1.522) and smoking (aHR 1.089, 95%CI 1.004-1.180) were independent predictors of intestinal resections. Survival analysis for biologic requirement, persistence, and the risk of intestinal resections is illustrated in Figure 1. Conclusion Ileal disease is associated with a higher requirement for biologic therapy, showing the poorest persistence. It also demonstrates the highest probability of intestinal resections among CD locations. These findings provide valuable insights into tailoring treatment strategies based on CD location.
背景克罗恩病(CD)因发病部位不同而在遗传学、炎症成分和微生物群方面存在差异。治疗效果可能与患病部位有关,但现有研究得出的结果并不一致。本研究旨在探讨 CD 所在位置对一线生物治疗需求和持续性以及肠切除风险的影响。方法 本研究考虑了 2005 年 1 月至 2023 年 5 月期间纳入前瞻性 ENEIDA 登记的 CD 患者。研究分析了人口统计学、疾病表型和部位、并发症、生物疗法的使用以及肠道手术。采用 Cox 比例危险度法和 Kaplan-Meier 法分析生物制剂需求和持续性以及手术风险。结果 共纳入 17,508 名患者,中位随访时间为 6 年(IQR 2-10 年)。最常见的疾病部位是回肠(43.3%)和回结肠(39%),结肠(16.4%)和上消化道疾病(1.2%)的发病率较低。54.5%的患者(n=9,543)首次使用生物制剂,与回肠和结肠疾病相比,回结肠疾病的5年需求量更高(60.1% vs 53% vs 49.9%,p<0.001)。与回结肠和结肠疾病相比,回肠疾病的 5 年持续率最低(39% vs 41.6% vs 45.1%,p=0.004)。回肠部位(aHR 1.084,95%CI 1.006-1.167)、女性性别(调整后危险比 [aHR] 1.173,95%CI 1.096-1.254)、肠道外表现(aHR 1.163,95%CI 1.080-1.251)、腹部手术史(aHR 1.539,95%CI 1.426-1.661)是停药的独立预测因素。肠切除术的累计需求为 25.8%(n=4,512),与回肠结肠和结肠位置相比,回肠疾病显示出最高的 5 年手术风险(19.5% vs 17.8 vs 8.3%,p<0.001)。回肠疾病(aHR 1.194,95%CI 1.101-1.295)、狭窄(aHR 2.575,95%CI 2.378-2.787)和穿透表型(aHR 2.485,95%CI 2.261-2.734)、生物治疗史(aHR 1.386,95%CI 1.262-1.522)和吸烟(aHR 1.089,95%CI 1.004-1.180)是肠切除的独立预测因素。图 1 显示了生物需求、持续性和肠切除风险的生存分析。结论 回肠疾病对生物制剂治疗的需求较高,显示出最差的持续性。同时,在 CD 病变部位中,回肠切除的概率也最高。这些发现为根据 CD 病变部位制定治疗策略提供了宝贵的见解。

Background Few small studies have assessed the efficacy of topical therapy with tacrolimus in patients with ulcerative colitis (UC). The aim of our study was to evaluate its effectiveness and safety in a real-world setting. Methods A multicenter observational retrospective study at 25 Spanish GETECCU hospitals was performed. Adult patients with UC who received topical tacrolimus from January 2009 to January 2023 were eligible. Inclusion criteria were proctitis, left-sided, or extensive colitis with persistent distal colonic activity confirmed endoscopically during the previous 3 months. Clinical and biochemical data were collected at baseline, week 4, 8 and 54. Tacrolimus trough levels were evaluated in week 4 and 8. Primary outcome was clinical response at week 8, defined as a ≥3 points or ≥30% decrease of partial Mayo score with ≥1point reduction in the bleeding score. Mean partial mayo scores were compared using the t-test. A p<0.05 was considered statistically significant. Results 106 patients, 59 (55.6%) males, median age 48.7 years (IQR:39.9-59.7), received rectal tacrolimus during a median of 9.7 weeks (IQR:5-18.7). Sixty-four patients (60.4%) received suppositories, 41 (38.7%) enemas and 1 patient an ointment (0.9%). Thirty (28.3%) were patients with proctitis, 45 (42.4%) with left colitis and 31 (29.2%) with extensive colitis. At baseline, 54 patients (50.9%) received concomitant biological/small molecules therapy, while 14 patients received immunomodulators. Most common dose was 2 mg (84%) Q24H (71.7%). A significant decrease in mean partial mayo score was observed at week 4 and 8 (figure 1). Clinical response at week 8 was achieved in 63 patients (66.3%) and clinical remission in 42 (44.2%). 32 patients (33.7%) were non-responder at week 8. Clinical response and remission at week 4 were achieved in 56 (57.7%) and 33 (34.4%), respectively. Clinical response at week 8 was similar between the group with concomitant biological therapy and without (64.6.9% vs 68.1%, p=0.8). Clinical response at week 8 was similar among different extensions (proctitis: 55.6%; left colitis: 80%; extensive colitis 57.1%; p=0.052). Clinical outcomes are detailed in table 1. Median tacrolimus trough levels at week 4 was 3.4 ng/ml (IQR 1.5-6.7) and 2.9 ng/ml (IQR 1.5-6) at week 8. Adverse events were detected in 21 patients (19.8%), Thirteen were graded as mild and 8 moderate. Treatment was ceased due to adverse events in 11 (10.4%) patients. Conclusion Topical tacrolimus is effective in UC achieving clinical response in more than sixty percent at week 8 with even lower doses than reported in clinical trials. Adverse events reported in nearly 20% of patients were mostly mild.
背景很少有小型研究对溃疡性结肠炎(UC)患者使用他克莫司局部治疗的疗效进行评估。我们的研究旨在评估其在实际环境中的有效性和安全性。方法 在西班牙 25 家 GETECCU 医院开展了一项多中心观察性回顾研究。研究对象为 2009 年 1 月至 2023 年 1 月期间接受局部他克莫司治疗的成人 UC 患者。纳入标准为直肠炎、左侧结肠炎或广泛性结肠炎,且在过去 3 个月中经内镜证实有持续的远端结肠活动。在基线、第 4 周、第 8 周和第 54 周收集临床和生化数据。在第 4 周和第 8 周评估他克莫司的谷值水平。主要结果是第 8 周时的临床反应,即部分马尤评分下降≥3 分或≥30%,出血评分下降≥1 分。部分梅奥评分的平均值采用 t 检验进行比较。P<0.05为有统计学意义。结果 106 名患者中,59 名(55.6%)男性,中位年龄 48.7 岁(IQR:39.9-59.7),接受直肠他克莫司治疗的中位时间为 9.7 周(IQR:5-18.7)。64名患者(60.4%)使用了栓剂,41名患者(38.7%)使用了灌肠剂,1名患者使用了软膏(0.9%)。30名患者(28.3%)患有直肠炎,45名患者(42.4%)患有左侧结肠炎,31名患者(29.2%)患有广泛性结肠炎。基线时,54 名患者(50.9%)同时接受生物/小分子治疗,14 名患者接受免疫调节剂治疗。最常见的剂量是 2 毫克(84%)Q24H(71.7%)。第4周和第8周观察到平均部分马约评分明显下降(图1)。第 8 周时,63 名患者(66.3%)获得临床应答,42 名患者(44.2%)获得临床缓解。32名患者(33.7%)在第8周时无应答。第 4 周分别有 56 名(57.7%)和 33 名(34.4%)患者出现临床反应和缓解。第8周时,同时接受生物治疗组与未接受生物治疗组的临床反应相似(64.6.9% vs 68.1%,P=0.8)。第 8 周时,不同扩展区的临床反应相似(直肠炎:55.6%;左侧结肠炎:80%;广泛性结肠炎:57.1%;P=0.052)。临床结果详见表 1。第 4 周时他克莫司谷值中位数为 3.4 纳克/毫升(IQR 1.5-6.7),第 8 周时为 2.9 纳克/毫升(IQR 1.5-6)。21名患者(19.8%)出现了不良反应,其中13例为轻度,8例为中度。有 11 名患者(10.4%)因不良反应而停止治疗。结论 外用他克莫司对 UC 有效,在第 8 周时,超过 60% 的患者获得了临床应答,其剂量甚至低于临床试验报告的剂量。近20%的患者报告的不良反应大多较轻。

Background Biologics, such as anti-TNFα agents, are commonly used in the management of Crohn’s disease (CD). A significant proportion of patients do not respond to treatment, necessitating the exploration of pre-treatment predictors of treatment response. Methods Anti-TNFα-naïve adults with active CD (Crohn’s Disease Activity Index; CDAI≥150) participating in an RCT (NCT04859088) were randomised to receive adalimumab monotherapy or adalimumab combination therapy with 50% partial enteral nutrition (PEN). Treatment response (CDAI<150) was assessed after 6 weeks, baseline diet was assessed with EPIC-Norfolk FFQ, alternative Mediterranean diet scores (aMED), and principal component analysis (PCA) with orthogonal (varimax) rotation was used to identify data-derived dietary patterns. Baseline predictors evaluated included PEN use, steroid use, immunomodulator use, age, disease duration, CDAI, C-Reactive protein (CRP), albumin, haemoglobin, Scottish Index of Multiple Deprivation (SIMD) score, adherence to dietary patterns identified, aMED score, smoking status, alcohol consumption, physical activity level, body mass index (BMI), fat mass (kg/m2), fat-free mass (kg/m2), and handgrip strength. Differential analysis between responders and non-responders was carried out with general linear model or chi-square test when appropriate. Random forest model with recursive feature elimination (RF-RFE) was used to identify the most predictive factors of treatment response. Results Of 42 participants recruited to the study, 62% (26) responded to treatment. PCA revealed four dietary patterns (Figure 1A). Responders to adalimumab were younger (mean (SD): 36.0 (17.1) vs 50.8 (10.0), P=0.004), had lower baseline CDAI (mean (SD): 228 (62) vs 286 (78), P=0.018), higher CRP (14.5 (19.2) vs 4.6 (5.8) mg/L, P=0.036), were less likely to smoke (31% (5 of 16) vs 8% (2 of 26), and less likely to adhere to a dietary pattern characterised by high consumption of animal products (PC2) (P=0.030). Adherence to PC2 also correlated positively with age (r=0.327, P=0.035). The RF-RFE algorithm highlighted young age, low baseline CDAI and low PC2 adherence as key factors (Sensitivity: 77%, Specificity: 63%, PPV: 77%, NPV: 63%, OOB: 29%, P=0.012) (Figure 1B). Interestingly, exclusion of dietary factors improved diagnostic performance of the model (Sensitivity: 77%, Specificity: 75%, PPV: 83%, NPV: 67%, OOB: 24%, P=0.003) (Figure 1C), indicating potential interactions by other factors like age. Conclusion Young age, non-smoking, low baseline CDAI and elevated CRP predict adalimumab response in anti-TNFα-naïve adults. While dietary factors may also play a role, their impact seems confounded by other non-dietary factors. Further research is warranted in this area.
背景 抗肿瘤坏死因子α等生物制剂是治疗克罗恩病(CD)的常用药物。相当一部分患者对治疗没有反应,因此有必要探索治疗前预测治疗反应的因素。方法 参与一项RCT(NCT04859088)研究的患有活动性克罗恩病(克罗恩病活动指数;CDAI≥150)的抗TNFα无效成人患者被随机分配接受阿达木单抗单药治疗或阿达木单抗联合治疗加50%部分肠内营养(PEN)。治疗反应(CDAI<150)在6周后进行评估,基线饮食通过EPIC-Norfolk FFQ、替代地中海饮食评分(aMED)进行评估,并使用正交(varimax)旋转主成分分析(PCA)确定数据衍生的饮食模式。评估的基线预测因素包括:使用 PEN、使用类固醇、使用免疫调节剂、年龄、病程、CDAI、C-反应蛋白 (CRP)、白蛋白、血红蛋白、苏格兰多重贫困指数 (SIMD) 评分、对已确定饮食模式的依从性、aMED 评分、吸烟状况、饮酒量、体力活动水平、体重指数 (BMI)、脂肪量 (kg/m2)、无脂肪量 (kg/m2) 和握力。在适当情况下,采用一般线性模型或卡方检验对应答者和非应答者进行差异分析。采用递归特征消除随机森林模型(RF-RFE)来确定对治疗反应最具预测性的因素。结果 在被招募参加研究的 42 名参与者中,62%(26 人)对治疗做出了反应。PCA显示了四种饮食模式(图1A)。阿达木单抗应答者更年轻(平均(标清):36.0(17.1) vs 50.8(10.0),P=0.004),基线 CDAI 更低(平均(标清):228(62) vs 286(78),P=0.018),CRP 更高(14.5(19.2) vs 4.6(5.8)毫克/升,P=0.036),较少吸烟(31%(16 人中有 5 人) vs 8%(26 人中有 2 人)),较少坚持以大量食用动物产品为特征的饮食模式(PC2)(P=0.030)。坚持 PC2 与年龄也呈正相关(r=0.327,P=0.035)。RF-RFE 算法强调年轻、低基线 CDAI 和低 PC2 依从性是关键因素(灵敏度:77%,特异度:63%,PPV:77%,NPV:63%,OOB:29%,P=0.012)(图 1B)。有趣的是,排除饮食因素后,模型的诊断性能有所提高(灵敏度:77%,特异性:75%,PPV:83%,NPV:67%,OOB:24%,P=0.003)(图 1C),这表明年龄等其他因素可能会产生相互作用。结论 年轻、不吸烟、基线 CDAI 低和 CRP 升高可预测抗肿瘤坏死因子α无效成人的阿达木单抗反应。虽然饮食因素也可能起到一定作用,但其影响似乎被其他非饮食因素所混淆。这一领域还需要进一步研究。

A significant proportion of patients do not respond to treatment, necessitating the exploration of pre-treatment predictors of treatment response. Methods Anti-TNFα-naïve adults with active CD (Crohn’s Disease Activity Index; CDAI≥150) participating in an RCT (NCT04859088) were randomised to receive adalimumab monotherapy or adalimumab combination therapy with 50% partial enteral nutrition (PEN). Treatment response (CDAI<150) was assessed after 6 weeks, baseline diet was assessed with EPIC-Norfolk FFQ, alternative Mediterranean diet scores (aMED), and principal component analysis (PCA) with orthogonal (varimax) rotation was used to identify data-derived dietary patterns. Baseline predictors evaluated included PEN use, steroid use, immunomodulator use, age, disease duration, CDAI, C-Reactive protein (CRP), albumin, haemoglobin, Scottish Index of Multiple Deprivation (SIMD) score, adherence to dietary patterns identified, aMED score, smoking status, alcohol consumption, physical activity level, body mass index (BMI), fat mass (kg/m2), fat-free mass (kg/m2), and handgrip strength. Differential analysis between responders and non-responders was carried out with general linear model or chi-square test when appropriate. Random forest model with recursive feature elimination (RF-RFE) was used to identify the most predictive factors of treatment response. Results Of 42 participants recruited to the study, 62% (26) responded to treatment. PCA revealed four dietary patterns (Figure 1A). Responders to adalimumab were younger (mean (SD): 36.0 (17.1) vs 50.8 (10.0), P=0.004), had lower baseline CDAI (mean (SD): 228 (62) vs 286 (78), P=0.018), higher CRP (14.5 (19.2) vs 4.6 (5.8) mg/L, P=0.036), were less likely to smoke (31% (5 of 16) vs 8% (2 of 26), and less likely to adhere to a dietary pattern characterised by high consumption of animal products (PC2) (P=0.030). Adherence to PC2 also correlated positively with age (r=0.327, P=0.035). The RF-RFE algorithm highlighted young age, low baseline CDAI and low PC2 adherence as key factors (Sensitivity: 77%, Specificity: 63%, PPV: 77%, NPV: 63%, OOB: 29%, P=0.012) (Figure 1B). Interestingly, exclusion of dietary factors improved diagnostic performance of the model (Sensitivity: 77%, Specificity: 75%, PPV: 83%, NPV: 67%, OOB: 24%, P=0.003) (Figure 1C), indicating potential interactions by other factors like age. Conclusion Young age, non-smoking, low baseline CDAI and elevated CRP predict adalimumab response in anti-TNFα-naïve adults. While dietary factors may also play a role, their impact seems confounded by other non-dietary factors. Further research is warranted in this area.","PeriodicalId":15453,"journal":{"name":"Journal of Crohn's and Colitis","volume":"88 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139559424","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
