Comparison between tofacitinib and ustekinumab as a third-line therapy in refractory ulcerative colitis: A multicenter international study.

BACKGROUND: Ustekinumab and tofacitinib have recently been approved for the management of moderate to severe ulcerative colitis (UC). However, there is no evidence on how they should be positioned in the therapeutic algorithm. The aim of this study was to compare tofacitinib and ustekinumab as third-line therapies in UC patients in whom anti-TNF and vedolizumab had failed. METHODS: This was a multicenter retrospective observational study. The primary outcome was disease progression, defined as the need for steroids, therapy escalation, UC-related hospitalization and/or surgery. Secondary outcomes were clinical remission, normalization of C-reactive protein, endoscopic remission, treatment withdrawal, and adverse events. RESULTS: One-hundred seventeen UC patients were included in the study and followed for a median time of 11.6 months (q1 -q3, 5.5-18.7). Overall, 65% of patients were treated with tofacitinib and 35% with ustekinumab. In the entire study cohort, 63 patients (54%) had disease progression during the follow-up period. Treatment with ustekinumab predicted increased risk of disease progression compared to treatment with tofacitinib in Cox regression analysis (HR: 1.93 [95% CI: 1.06-3.50] p = 0.030). Twenty-eight (68%) patients in the ustekinumab group and 35 (46%) in the tofacitinib group had disease progression over the follow-up period (log-rank test, p < 0.054). No significant differences were observed for the secondary outcomes. Six and 22 adverse events occurred in the ustekinumab and tofacitinib groups, respectively (15% vs. 31%, p = 0.11). CONCLUSIONS: Tofacitinib was more efficacious in reducing disease progression than ustekinumab in this cohort of refractory UC patients. However, prospective head-to-head clinical trials are needed as to confirm these data.

Prophylactic versus endoscopy-driven treatment of Crohn's postoperative recurrence: A retrospective, multicentric European study (PORCSE study).

BACKGROUND AND AIMS: No consensus exists on optimal strategy to prevent postoperative recurrence (POR) after ileocecal resection (ICR) for Crohn's disease (CD).We compared early medical prophylaxis versus expectant management with treatment driven by findings at elective endoscopy 6-12 months after ICR. METHODS: A retrospective, multicentric, observational study was performed. CD-patients undergoing first ICR were assigned to cohort1 if a biologic or immunomodulator was (re)started prophylactically after ICR, or to cohort2 if no postoperative prophylaxis was given and treatment was started as reaction to elective endoscopic findings. Primary endpoint was rate of endoscopic POR (Rutgeerts>i1). Secondary endpoints were severe endoscopic POR (Rutgeerts i3/i4), clinical POR, surgical POR and treatment burden during follow-up. RESULTS: Of 346 included patients, 47.4% received prophylactic postoperative treatment (proactive/cohort1) and 52.6% did not (reactive/cohort2).Endoscopic POR (Rutgeerts>i1) rate was significantly higher in cohort2 (41.5% vs 53.8%, OR1.81, P=0.039) at endoscopy 6-12 months after surgery. No significant difference in severe endoscopic POR was found (OR1.29, P=0.517). Cohort2 had significantly higher clinical POR rates (17.7% vs 35.7%, OR3.05, P=0.002) and numerically higher surgical recurrence rates (6.7% vs 13.2%, OR2.59, P=0.051). Cox proportional hazards regression analysis showed no significant difference in time to surgical POR of proactive versus expectant/reactive approach (HR2.50, P=0.057). Quasi-Poisson regression revealed a significantly lower treatment burden for immunomodulator use in cohort2 (mean ratio 0.53, P=0.002), but no difference in burden of biologics or combination treatment. CONCLUSIONS: The PORCSE study showed lower rates of endoscopic POR with early postoperative medical treatment compared to expectant management after first ileocecal resection for Crohn's disease.

The Inflammatory Bowel Disease-Disk Tool for Assessing Disability in Inflammatory Bowel Disease Patients: Validation of the Greek Version.

BACKGROUND: The Inflammatory Bowel Disease-Disk (IBD-Disk) is a physician-administered tool that evaluates the functional status of patients with Inflammatory Bowel Disease (IBD). The aim of our study was to validate the content of the IBD-Disk in a Greek cohort of IBD patients. METHODS: Two questionnaires [the IBD Disk and the IBD-Disability Index (IBD-DI)] were translated into Greek and administered to IBD patients at baseline visit, after 4 weeks and 6 months. Validation of the IBD Disk included measuring of concurrent validity, reproducibility, and internal consistency. RESULTS: A total of 300 patients were included at baseline and 269 at follow-up. There was a good correlation between the total scores of the IBD-Disk and IBD-DI at baseline (Pearson correlation 0.87, p < 0.001). Reproducibility of the total IBD-Disk score was very good [intra-class correlation coefficient (ICC), 95% confidence interval (CI) 0.89 (0.86-0.91)]. Cronbach's coefficient alpha for all items achieved 0.90 (95%CI 0.88-0.92), demonstrating a very good homogeneity of the IBD-Disk items. Female gender and extraintestinal manifestations were significantly associated with a higher IBD-Disk total score. CONCLUSIONS: The Greek version of the IBD-Disk proved to be a reliable and valid tool in detecting and assessing IBD-related disability in a Greek cohort of IBD patients.

Pharmacogenetic Analysis of the MIR146A rs2910164 and MIR155 rs767649 Polymorphisms and Response to Anti-TNF Treatment in Patients with Crohn's Disease and Psoriasis.

The clinical heterogeneity regarding the response profile of the antitumor necrosis factor (anti-TNF) in patients with Crohn's disease (CD) and psoriasis (PsO) is attributed, amongst others, to genetic factors that influence the regulatory mechanisms which orchestrate the inflammatory response. Here, we investigated the possible associations between the MIR146A rs2910164 and MIR155 rs767649 variants and the response to anti-TNF therapy in a Greek cohort of 103 CD and 100 PsO patients. We genotyped 103 CD patients and 100 PsO patients via the PCR-RFLP method, utilizing the de novo formation of a restriction site for the SacI enzyme considering the MIR146A rs2910164, while Tsp45I was employed for the MIR155 rs767649 variant. Additionally, we investigated the potential functional role of the rs767649 variant, exploring in silico the alteration of transcription factor binding sites (TFBSs) mapped on its genomic location. Our single-SNP analysis displayed a significant association between the rare rs767649 A allele and response to therapy (Bonferroni-corrected p value = 0.012) in patients with PsO, a result further enhanced by the alteration in the IRF2 TFBS caused by the above allele. Our results highlight the protective role of the rare rs767649 A allele in the clinical remission of PsO, implying its utilization as a pharmacogenetic biomarker.

Post-inflammatory Polyp Burden as a Prognostic Marker of Disease-outcome in Patients with Inflammatory Bowel Disease.

BACKGROUND AND AIMS: Post-inflammatory polyps [PIPs] are considered as indicators of previous episodes of severe inflammation and mucosal ulceration. Inflammatory bowel disease [IBD], namely Crohn's disease [CD] and ulcerative colitis [UC], exhibit a perpetuating, relapsing and remitting pattern, and PIPs are a frequent sequela of chronicity. The aim of this study was to determine whether a high PIP burden is associated with a more severe disease course in patients with IBD. METHODS: This was a multinational, multicentre, retrospective study. IBD patients previously diagnosed with PIPs were retrieved from the endoscopic database of each centre. PIP burden was evaluated and associated with demographic and clinical data as well as factors indicating a more unfavourable disease course. RESULTS: A total of 504 IBD patients with PIPs were recruited [male: 61.9%]. The mean age at IBD diagnosis was 36.9 [±16.8] years. Most patients [74.8%] were diagnosed with UC. A high PIP burden was present in 53.4% of patients. On multivariable Cox regression analysis, a high PIP burden was independently associated with treatment escalation (hazard ratio [HR] 1.35, 95% confidence interval [CI] 1.04-1.75; p = 0.024), hospitalization [HR 1.90; 95% CI 1.24-2.90; p = 0.003], need for surgery [HR 2.28; 95% CI 1.17-4.44, p = 0.02] and younger age at diagnosis [HR 0.99, 95% CI 0.98-0.99; p = 0.003]. CONCLUSION: PIP burden was associated with a more severe outcome. Future prospective studies should focus on the characterization of PIP burden as to further risk stratify this patient cohort.

Patients With Inflammatory Bowel Diseases Have Impaired Antibody Production After Anti-SARS-CoV-2 Vaccination: Results From a Panhellenic Registry.

BACKGROUND: Four EMA-approved vaccines against SARS-CoV-2 are currently available. Data regarding antibody responses to initial vaccination regimens in patients with inflammatory bowel diseases (IBD) are limited. METHODS: We conducted a prospective, controlled, multicenter study in tertiary Greek IBD centers. Participating patients had completed the initial vaccination regimens (1 or 2 doses, depending on the type of COVID-19 vaccine) at least 2 weeks before study enrolment. Anti-S1 IgG antibody levels were measured. Demographic and adverse events data were collected. RESULTS: We tested 403 patients (Crohn's disease, 58.9%; male, 53.4%; median age, 45 years) and 124 healthy controls (HCs). Following full vaccination, 98% of patients seroconverted, with mRNA vaccines inducing higher seroconversion rates than viral vector vaccines (P = .021). In total, IBD patients had lower anti-S1 levels than HCs (P < .001). In the multivariate analysis, viral vector vaccines (P < .001), longer time to antibody testing (P < .001), anti-TNFα treatment (P = .013), and age (P = .016) were independently associated with lower anti-S1 titers. Vedolizumab monotherapy was associated with higher antibody levels than anti-TNFα or anti-interleukin-12/IL-23 monotherapy (P = .023 and P = .032). All anti- SARS-CoV-2 vaccines were safe. CONCLUSIONS: Patients with IBD have impaired antibody responses to anti-SARS-CoV-2 vaccination, particularly those receiving viral vector vaccines and those on anti-TNFα treatment. Older age also hampers antibody production after vaccination. For those low-response groups, administration of accelerated or prioritized booster vaccination may be considered.

Thisis a multicenter study on IBD patients after COVID-19 vaccination and anti-S1 IgG antibody levels measurement. Patients with IBD have lower antibody responses than healthy controls, particularly those receiving viral vector vaccines and those on anti-TNFα or combination treatment.

I-CARE, a European Prospective Cohort Study Assessing Safety and Effectiveness of Biologics in Inflammatory Bowel Disease.

BACKGROUND AND AIMS: There is a need to evaluate the benefit-risk ratio of current therapies in inflammatory bowel disease (IBD) patients to provide the best quality of care. The primary objective of I-CARE (IBD Cancer and serious infections in Europe) was to assess prospectively safety concerns in IBD, with specific focus on the risk of cancer/lymphoma and serious infections in patients treated with anti-tumor necrosis factor and other biologic monotherapy as well as in combination with immunomodulators. METHODS: I-CARE was designed as a European prospective longitudinal observational multicenter cohort study to include patients with a diagnosis of Crohn's disease, ulcerative colitis, or IBD unclassified established at least 3 months prior to enrollment. RESULTS: A total of 10,206 patients were enrolled between March 2016 and April 2019, including 6169 (60.4%) patients with Crohn's disease, 3853 (37.8%) with ulcerative colitis, and 184 (1.8%) with a diagnosis of IBD unclassified. Thirty-two percent of patients were receiving azathioprine/thiopurines, 4.6% 6-mercaptopurine, and 3.2% methotrexate at study entry. At inclusion, 47.3% of patients were treated with an anti-tumor necrosis factor agent, 8.8% with vedolizumab, and 3.4% with ustekinumab. Roughly one-quarter of patients (26.8%) underwent prior IBD-related surgery. Sixty-six percent of patients had been previously treated with systemic steroids. Three percent of patients had a medical history of cancer prior to inclusion and 1.1% had a history of colonic, esophageal, or uterine cervix high-grade dysplasia. CONCLUSIONS: I-CARE is an ongoing investigator-initiated observational European prospective cohort study that will provide unique information on the long-term benefits and risks of biological therapies in IBD patients.

Pharmacogenetic analysis of canonical versus noncanonical pathway of NF-kB in Crohn's disease patients under anti-tumor necrosis factor-α treatment.

OBJECTIVES: This study explores the potential of gene polymorphisms in the canonical and noncanonical NF-kB signaling pathway as a prediction biomarker of anti-tumor necrosis factor (TNF)α response in Crohn's patients. MATERIALS AND METHODS: A total of 109 Greek patients with Crohn's disease (CD) were recruited, and the genotype of TLR2 rs3804099, LTA rs909253, TLR4 rs5030728, and MAP3K14/NIK rs7222094 single nucleotide polymorphisms was investigated for association with response to anti-TNFα therapy. Patient's response to therapy was based on the Crohn's Disease Activity Index, depicting the maximum response within 24 months after initiation of treatment. RESULTS: Seventy-three patients (66.7%) were classified as responders while 36 as nonresponders (33.3%). Comparing allelic frequencies between responders and nonresponders, the presence of TLR2 rs3804099 T allele was associated with nonresponse (P = 0.003), even after stratification by anti-TNFα drugs (infliximab: P = 0.032, adalimumab: P = 0.026). No other association was identified for the rest of the polymorphisms under study. Haplotype analysis further enhanced the association of rs3804099 T allele with loss of response, even though the results were NS (P = 0.073). CONCLUSION: Our results suggest that polymorphisms in the canonical NF-kB pathway genes could potentially act as a predictive biomarker of anti-TNFα response in CD.

Endoscopic Postoperative Recurrence in Crohn's Disease After Curative Ileocecal Resection with Early Prophylaxis by Anti-TNF, Vedolizumab or Ustekinumab: A Real-World Multicentre European Study.

BACKGROUND: Endoscopic-post-operative-recurrence [ePOR] in Crohn's disease [CD] after ileocecal resection [ICR] is a major concern. We aimed to evaluate the effectiveness of early prophylaxis with biologics and to compare anti-tumour necrosis factor [anti-TNF] therapy to vedolizumab [VDZ] and ustekinumab [UST] in a real-world setting. METHODS: A retrospective multicentre study of CD-adults after curative ICR on early prophylaxis was undertaken. ePOR was defined as a Rutgeerts score [RS] ≥ i2 or colonic-segmental-SES-CD ≥ 6. Multivariable logistic regression was used to evaluate risk factors, and inverse probability treatment weighting [IPTW] was applied to compare the effectiveness between agents. RESULTS: The study included 297 patients (53.9% males, age at diagnosis 24 years [19-32], age at ICR 34 years [26-43], 18.5% smokers, 27.6% biologic-naïve, 65.7% anti-TNF experienced, 28.6% two or more biologics and 17.2% previous surgery). Overall, 224, 39 and 34 patients received anti-TNF, VDZ or UST, respectively. Patients treated with VDZ and UST were more biologic experienced with higher rates of previous surgery. ePOR rates within 1 year were 41.8%. ePOR rates by treatment groups were: anti-TNF 40.2%, VDZ 33% and UST 61.8%. Risk factors for ePOR at 1 year were: past-infliximab (adjusted odds ratio [adj.OR] = 1.73 [95% confidence interval, CI: 1.01-2.97]), past-adalimumab [adj.OR = 2.32 [95% CI: 1.35-4.01] and surgical aspects. After IPTW, the risk of ePOR within 1 year of VDZ vs anti-TNF or UST vs anti-TNF was comparable (OR = 0.55 [95% CI: 0.25-1.19], OR = 1.86 [95% CI: 0.79-4.38]), respectively. CONCLUSION: Prevention of ePOR within 1 year after surgery was successful in ~60% of patients. Patients treated with VDZ or UST consisted of a more refractory group. After controlling for confounders, no differences in ePOR risk were seen between anti-TNF prophylaxis and other groups.

Corticosteroids and Mesalamine Versus Corticosteroids for Acute Severe Ulcerative Colitis: A Randomized Controlled Trial.

BACKGROUND & AIMS: Corticosteroids are the mainstay of treatment for hospitalized patients with acute severe ulcerative colitis (ASUC). However, whether the addition/continuation of mesalamine with corticosteroids during hospitalization is superior to corticosteroids alone is unknown. METHODS: This was a randomized controlled, investigator-blinded, clinical trial conducted in 10 centers in 7 countries. Patients hospitalized with ASUC (Lichtiger score ≥10) were eligible. Patients received corticosteroids alone or corticosteroid + mesalamine (4 g/day mesalamine) by a stratified randomization according to mesalamine use before admission. The primary outcome was the percentage of patients who responded to treatment by day 7, defined by a drop >3 points in the Lichtiger score and an absolute score <10 without the need for rescue medications or colectomy. RESULTS: Three hundred forty-six patients were screened, and 149 were included (70/149 female; median age, 41 years). Of these, 73 received corticosteroids + mesalamine, and 76 received corticosteroids alone. For the primary outcome, 53 of 73 patients (72.6%) receiving corticosteroids with mesalamine responded versus 58 of 76 patients (76.3%) on corticosteroids alone (odds ratio, 0.82; 95% confidence interval, 0.39-1.72; P = .60). There was no difference between groups in duration of hospitalization, C-reactive protein normalization rate, or colectomy rate up to day 90. The need for biologics among patients receiving combination of corticosteroids with mesalamine was numerically lower by day 30 (P = .11) and day 90 (P = .07). CONCLUSIONS: In this randomized controlled trial, combination of mesalamine with corticosteroids did not benefit hospitalized patients with ASUC more than corticosteroids alone. An exploratory signal for a reduced need for biologics at 90 days in the mesalamine group merits further evaluation. CLINICALTRIALS: gov ID: NCT01941589.

Mental Health, Work Presenteeism, and Exercise in Inflammatory Bowel Disease.

BACKGROUND: Chronic diseases, such as IBD, can lead to anxiety and depression which can have a significant impact on productivity at work [presenteeism]. The aim of this study was to assess the prevalence of depression/anxiety, presenteeism and exercise levels among IBD patients. METHODS: This was a multicentre study whereby adult IBD patients, in clinical remission, were asked to answer a questionnaire anonymously. Hospital Anxiety and Depression Score [HADS], Stanford Presenteeism Scale [SPS-6] and Godin Exercise Score were also collected. RESULTS: A total of 585 patients were recruited. The majority had Crohn's disease [CD, 62.2%] and were male [53.0%], with a median age of 39 years [IQR 30-49]. A psychiatric diagnosis was present in 10.8% of patients prior to their IBD diagnosis. A further 14.2% of patients were psychiatrically diagnosed after IBD diagnosis, this being commoner in CD patients [41.6% of CD, p <0.01]. A raised HADS-Anxiety or a HADS-Depression score ≥8 was present in 46.1% of patients, with 27.4% having a score ≥11. Low presenteeism at work was present in 34.0%. Patients diagnosed with depression/anxiety had a more sedentary lifestyle [p <0.01], lower presenteeism at work [p <0.01] and a higher rate of unemployment [p <0.01]. CONCLUSIONS: A significant percentage of IBD patients in remission suffer from anxiety and/or depression. Risk factors for these are CD, female gender, use of biologic medications, long-standing and/or perianal disease. Depression/anxiety was associated with a sedentary lifestyle, lower presenteeism at work and unemployment. Validated screening tools and appropriate referrals to psychologists and/or psychiatrists should be employed within IBD clinics.

Real-World Use and Adverse Events of SARS-CoV-2 Vaccination in Greek Patients with Inflammatory Bowel Disease.

Since inflammatory bowel disease (IBD) patients were excluded from vaccine authorization studies, limited knowledge exists regarding perceptions and unfavorable effects of COVID-19 vaccination in this group. We aimed to investigate the real-world use and adverse events (AEs) of COVID-19 vaccines in Greek IBD patients. Fully vaccinated IBD patients followed in Greek centers were invited to participate. All patients filled out an anonymous online survey concerning the vaccination program, which included information regarding demographics, clinical characteristics, treatment, vaccination perceptions and potential AEs. Overall, 1007 IBD patients were included. Vaccine hesitancy was reported by 49%. Total AEs to vaccination were reported by 81% after dose 1 (D1) and 76% after dose 2 (D2), including isolated injection site reactions (36% and 24% respectively). Systemic AEs were more common after D2 (51%, D2 vs. 44%, D1, p < 0.0001). Very few patients reported new onset abdominal symptoms (abdominal pain 4% (D1), 6% (D2) and diarrhea 5% (D1), 7% (D2)). There were no serious AEs leading to emergency room visit or hospitalization. In multivariate analysis, AEs occurrence was positively associated with young age and female gender (p < 0.0005 for both doses), whereas inactive disease was negatively associated with AE in D1 (p = 0.044). SARS-CoV-2 vaccination in Greek IBD patients demonstrated a favorable and reassuring safety profile.

When disease extent is not always a key parameter: Management of refractory ulcerative proctitis.

BACKGROUND: Patients with ulcerative proctitis represent a sub-group of ulcerative colitis patients with specific characteristics. Disease-related symptoms, endoscopic findings and patient's personality perspectives create a difficult-to-assess condition in certain cases. OBJECTIVES: To summarize available evidence on the management of refractory ulcerative proctitis and provide insights in treatment options. RESULTS: /Conclusion: Topical therapy plays a central role due to the location of the disease. However, well-established treatment options may become exhausted in a considerable proportion of ulcerative proctitis patients, indicating the need to advance to more potent therapies in order to induce and maintain clinical response and remission in these refractory cases. Systemic corticosteroids, thiopurines, calcineurin inhibitors, biologic agents and small molecules have all been tested with variable success rates. Investigational interventions as well as surgical procedures are kept as the ultimate resort in multi-treatment resistant cases. Identifying early prognostic factors that herald a disabling disease progression will help in optimizing treatment and avoiding surgery.

Implementation and Short-term Adverse Events of Anti-SARS-CoV-2 Vaccines in Inflammatory Bowel Disease Patients: An International Web-based Survey.

INTRODUCTION: Anti-SARS-CoV-2 vaccine clinical trials did not include patients with immune-mediated conditions such as inflammatory bowel disease [IBD]. We aimed to describe the implementation of anti-SARS-CoV-2 vaccination among IBD patients, patients' concerns, and the side effect profile of the anti-SARS-CoV-2 vaccines, using real-world data. METHODS: An anonymous web-based self-completed survey was distributed in 36 European countries between June and July 2021. The results of the patient characteristics, concerns, vaccination status, and side effect profile were analysed. RESULTS: In all 3272 IBD patients completed the survey, 79.6% had received at least one dose of anti-SARS-CoV-2 vaccine, and 71.7% had completed the vaccination process. Patients over 60 years old had a significantly higher rate of vaccination [p < 0.001]. Patients' main concerns before vaccination were the possibility of having worse vaccine-related adverse events due to their IBD [24.6%], an IBD flare after vaccination [21.1%], and reduced vaccine efficacy due to IBD or associated immunosuppression [17.6%]. After the first dose of the vaccine, 72.4% had local symptoms and 51.4% had systemic symptoms [five patients had non-specified thrombosis]. Adverse events were less frequent after the second dose of the vaccine and in older patients. Only a minority of the patients were hospitalised [0.3%], needed a consultation [3.6%], or had to change IBD therapy [13.4%] after anti-SARS-CoV-2 vaccination. CONCLUSIONS: Although IBD patients raised concerns about the safety and efficacy of anti-SARS-CoV-2 vaccines, the implementation of vaccination in those responding to our survey was high and the adverse events were comparable to the general population, with minimal impact on their IBD.

Diagnosis and Outcome of Extranodal Primary Intestinal Lymphoma in Inflammatory Bowel Disease: An ECCO CONFER Case Series.

BACKGROUND: There is a small but measurable increased risk of lymphoma in inflammatory bowel disease [IBD], with a suggestion that primary intestinal lymphoma [PIL] in IBD is associated with inflamed tissue and immunosuppressant use, mainly thiopurines. METHODS: This multicentre case series was supported by the European Crohn's and Colitis Organisation [ECCO] and performed as part of the Collaborative Network of Exceptionally Rare case reports [CONFER] project. Clinical data were recorded in a standardized case report form. RESULTS: Fifteen patients with intestinal lymphoma from eight centres were included (12 males, 11 patients with Crohn's disease [CD], mean age 47.8 [±16.4 SD, range 26-76] years at lymphoma diagnosis). Lymphoma type was diffuse large B-cell lymphoma [DLBCL] in eight, Hodgkin's disease in two, mucosa-associated lymphoid tissue [MALT] lymphoma in three, and single cases of immunoblastic lymphoma and indolent T-cell lymphoma. Lymphoma was located within the IBD-affected area in ten patients. At lymphoma diagnosis, nine patients had a history of azathioprine or anti-tumour necrosis factor [TNF] use. Lymphoma was diagnosed at a mean time of 10.4 [±7.07, 1-24] years after IBD diagnosis in 11 patients, prior to IBD in two and concurrently in two. Sustained remission over a median follow-up time of 6.5 [1.5-20] years was achieved in ten patients after treatment; five of them had started biological therapy [including anti-TNFs, vedolizumab and ustekinumab] for active CD subsequent to their PIL treatment. CONCLUSION: In this small case series, two-thirds of patients developed lymphoma in the IBD-affected area, and almost two-thirds had a history of thiopurine or anti-TNF use. Biologics were restarted without recurrence of lymphoma in half of the remitters.

ECCO Guidelines on Therapeutics in Ulcerative Colitis: Surgical Treatment.

This is the second of a series of two articles reporting the European Crohn's and Colitis Organisation [ECCO] evidence-based consensus on the management of adult patients with ulcerative colitis [UC]. The first article is focused on medical management, and the present article addresses medical treatment of acute severe ulcerative colitis [ASUC] and surgical management of medically refractory UC patients, including preoperative optimisation, surgical strategies, and technical issues. The article provides advice for a variety of common clinical and surgical conditions. Together, the articles represent an update of the evidence-based recommendations of the ECCO for UC.

Orofacial Granulomatosis Associated with Crohn's Disease: a Multicentre Case Series.

BACKGROUND: Orofacial granulomatosis [OFG] is a rare syndrome that may be associated with Crohn's disease [CD]. We aimed to characterise this relationship and the management options in the biologic era. METHODS: This multicentre case series was supported by the European Crohn's and Colitis Organisation [ECCO], and performed as part of the Collaborative Network of Exceptionally Rare case reports [CONFER] project. Clinical data were recorded in a standardised collection form. RESULTS: This report includes 28 patients with OFG associated with CD: 14 males (mean age of 32 years, ±12.4 standard deviation [SD]) and 14 females [40.3 years, ±21.0 SD]. Non-oral upper gastrointestinal tract involvement was seen in six cases and perianal disease in 11. The diagnosis of OFG was made before CD diagnosis in two patients, concurrently in eight, and after CD diagnosis in 18. The distribution of OFG involved the lips in 16 cases and buccal mucosa in 18. Pain was present in 25 cases, with impaired swallowing or speaking in six. Remission was achieved in 23 patients, notably with the use of anti-tumour necrosis factors [TNFs] in nine patients, vedolizumab in one, ustekinumab in one, and thalidomide in two. A further five cases were resistant to therapies including anti-TNFs. CONCLUSIONS: OFG associated with CD may occur before, concurrently with, or after the diagnosis of CD. Perianal and upper gastrointestinal [UGI] disease are common associations and there is a significant symptom burden in many. Remission can be obtained with a variety of immunosuppressive treatments, including several biologics approved for CD.
