Background: Several studies have reported positive efficacy outcomes for patients with inflammatory bowel disease treated with CT-P13, an infliximab biosimilar. Data from follow-up periods longer than 1 year are still scarce. Here, we assessed the long-term efficacy data, loss of response and safety after switching from infliximab to CT-P13 in patients with inflammatory bowel disease. Methods: This was a prospective single-center observational study involving patients with moderate-to-severe Crohn’s disease and ulcerative colitis switched from infliximab to CT-P13 treatment and reviewed up to 24 months. Efficacy and loss of response were measured using the Harvey–Bradshaw (HB) index and partial Mayo score for patients with Crohn’s disease and ulcerative colitis respectively. C-reactive protein, infliximab drug levels, adverse events and antidrug antibodies were also monitored throughout the study. Results: A total of 64 patients with Crohn’s disease and 36 patients with ulcerative colitis were included. Most of them (72%) remained on CT-P13. Overall, 28% of patients discontinued the therapy due to loss of response, adverse events or long-lasting clinical remission. Remission at 18 and 24 months occurred in 69.9% and 68.5% of patients, respectively. Dose increase was performed in 22% of patients, with remission being reached in 60% of them. HB index, partial Mayo score, C-reactive protein and infliximab drug levels did not show significant changes. Serious adverse events were reported in 14% of patients. Overall, two patients developed low levels of antidrug antibodies. Conclusions: Most of the patients switching from original infliximab were maintained on CT-P13 at 2 years of follow up with a good profile of efficacy and safety.

Abstract Background Studies have reported good efficacy outcomes for patients with inflammatory bowel disease (IBD) treated with biosimilars. There are limited long-term data. We assessed the long-term efficacy data and safety after switching from adalimumab to adalimumab biosimilars in patients with IBD. Methods A prospective single-centre observational study involving patients with Crohn’s disease or ulcerative colitis switched from adalimumab to adalimumab biosimilar and reviewed up to 12months. Efficacy and loss of response were measured using the Harvey–Bradshaw (HB) index and partial Mayo score for patients with Crohn’s disease and ulcerative colitis respectively. Blood tests including C-reactive protein, adalimumab drug levels and anti-drug antibodies were monitored. We have recorded side effects and possible serious adverse effects. The plan is to continue the study for 24 months. Results 109 patients with IBD have completed at least 6 months of treatment with adalimumab biosimilar, 12 of which have ulcerative colitis and 97 Crohn’s disease. Most of them (88%) continued on biosimilar after 6 months. Patients discontinued the therapy due to loss of response or development of antibodies in one case. Two patients were switched to a different biosimilar due to the presence of side effects which were however not serious. Of those who remained on the treatment, 74.5% were in clinical remission at 6 months and 71.4% at 9 months. HB index, partial Mayo score, C-reactive protein and adalimumab drug levels did not show significant changes. We have not reported any serious adverse events. We hope than by February, at least 60% of these patients will have been on Adalimumab for 12 months and further amended date would be added. Conclusion Most of the patients switching from original adalimumab were maintained on biosimilar at 6 and 12months of follow-up with similar efficacy and safety as the original drug.

Abstract Background Studies have reported good efficacy outcomes for patients with inflammatory bowel disease (IBD) treated with biosimilars. There are limited long term data. We assessed the long-term efficacy data and safety after switching from adalimumab to adalimumab biosimilar Imraldi in patients with IBD. Methods A prospective single-centre observational study involving patients with Crohn’s disease or ulcerative colitis switched from adalimumab originator to adalimumab biosimilar and reviewed up to 24months. Efficacy and loss of response were measured using the Harvey–Bradshaw (HB) index and partial Mayo score for patients with Crohn’s disease and ulcerative colitis respectively. Blood tests including C-reactive protein, adalimumab drug levels and antidrug antibodies were monitored. We have recorded side effects and possible serious adverse effects including COVID 19 infection. Results 113 patients were switched to Adalimumab biosimilar Imraldi from Adalimumab originator between January 2019 to March 2019. After 12 months of treatment, 25 patients interrupted treatment and 89 (78.8%) continued. These were analysed after 24 months of treatment - 57 (52.3%) continued on Imraldi. Of those who discontinued, 9 were switched back to Adalimumab originator due to side effects, and 34 stopped treatment - 16 patients due to loss of response, 11 patients developed antibodies, 5 underwent a surgery, 4 were in remission and 4 did not tolerate side effects. There was no statistical difference in CRP or Adalimumab levels prior to switch, at 12 months and at 24 months between the patients who continued or discontinued treatment. Overall, 18 of the patients who completed 24 months of treatment reported side effects, most frequently pain after injection (9 patients), followed by skin rash and recurrent infections (in 3 patients each). No patient was diagnosed with COVID 19 during until now. Conclusion After 24 months of follow up, 52.3% patients continued on adalimumab biosimilar and no serious side effects were reported. In particular, none of our patients acquired COVID 19 infection.

Abstract Background Adalimumab (ADA) is one of the most preferred anti-TNF agents because of its ease of use in real life. We aimed to evaluate the efficacy of ADA in the long-term period of inflammatory bowel disease (IBD) patients. Methods Patients treated with adalimumab (ADA) as the first- and second-line biological treatment for mild to moderate active IBD between January 2009 and March 2019 were included. The clinical and endoscopic response rate of ADA were evaluated, retrospectively. Remission was defined in ulcerative colitis patients (UC), if stool frequency ≤ 3/day with no bleeding and no mucosal lesions at the colonoscopy. Remission was defined in Crohn’s disease patients (CD) if CDAI < 150 and mucosal healing at the colonoscopy. Results Fifty-eight patients (81% Crohn’s disease, 58.6% biologic naive) were included in this study. Mean age was 41.4 ± 12.3 years old (19–67 years) and 46.6% of them were female. Median follow-up time was 57 months in UC and 65 months in Crohn’s disease (CD). Infliximab experience rate before ADA in UC and CD was 36.4%, 42.6%, respectively. CD’s related surgery rate was 43.5%; surgery rate 87.5% before ADA therapy and 12.5% after ADA treatment. Clinical and endoscopic remission rates were 81.8% / 63.6% and 89.4%/ 63.4 in UC and CD, respectively at the end of follow-up period. Loss of response rate was 20% in UC and 28.3% in CD (table). Mean months for loss of response were 42 ± 25.4 months and 29.7 ± 12 months in UC and CD, respectively. Clinical remission was obtained by dose escalation in 66% of CD patients who had response loss. Loss of response rate was not significantly different between IFX naive and IFX experienced patients (p > 0.05). There was no significant adverse event during the follow-up period. Conclusion In real life, the efficacy of ADA treatment is high in mild-to-moderate active IBD. Endoscopic remission was also acceptable for this group of patients.

Összefoglaló. Bevezetés: A gyulladásos bélbetegségek kezelésében a tumornekrózisfaktor-alfa-ellenes (anti-TNFα) antitestek elsődleges választási lehetőséget jelentenek a kortikoszteroid- és immunmoduláns kezelésre refrakter páciensek kezelési stratégiájában. Ezek a hatóanyagok hatékonyak, ám hosszú távú hatásosságukkal kapcsolatban sok az ellentmondás. Célkitűzés: Vizsgálatunk célja megvizsgálni az anti-TNFα-terápia (infliximab [IFX], adalimumab [ADA]) hosszú távú hatékonyságát gyulladásos bélbetegek körében. Módszerek: Retrospektív, adatgyűjtéses vizsgálatunkba a Szegedi Tudományegyetem I. Sz. Belgyógyászati Klinikáján gondozott, 18–65 év közötti gyulladásos bélbetegeket vontunk be. Az adatgyűjtést a Klinika informatikai rendszeréből végeztük a betegek ambuláns megjelenéseinek kezelőlapjaiból, illetve a zárójelentésekből. Eredmények: 102 beteg adatait elemeztük (Crohn-beteg: 67 fő, colitis ulcerosás: 35 fő). A Crohn-betegség diagnózisát követően átlagosan 7,84 év, a colitis ulcerosa diagnózisát követően átlagosan 9,86 év telt el az első anti-TNFα-terápia elkezdéséig. Az első kezelési ciklus átlagosan 2,64 évig tartott, a ciklus végén az IFX-t kapó betegek 50%-ánál, az ADA-t kapó betegek 46%-ánál volt remisszióban a betegség. A második kezelési ciklus átlagosan 4,67 évig tartott, a ciklus végén az IFX-t kapó betegek 36%-a, az ADA-t kapó betegek 40%-a volt remisszióban. Az első, illetve a második kezelési ciklus alatt az allergiás reakciók gyakorisága IFX esetében 13% és 18%, ADA esetében 4% és 3% volt. A primer hatástalanság és a másodlagos hatásvesztés az első ciklusban IFX esetében 4% és 10,5%, ADA esetében 11,5% és 19% volt. A második kezelési ciklusban IFX esetében 9%-ban és 18%-ban, ADA esetében 23%-ban és 10%-ban jelentették a ciklus végét. Következtetés: Az anti-TNFα-terápiák eredményeink alapján hosszú távon is hatékonynak és biztonságosnak bizonyultak. Másodlagos hatásvesztés kisebb arányban fordult elő a vizsgált populációban az irodalmi adatokhoz képest. Orv Hetil. 2020; 161(47): 1989–1994. Summary. Introduction: Anti-tumor necrosis factor-alpha (anti-TNFα) treatment is reserved for steroid-dependent or steroid/immunomodulator-refractory inflammatory bowel diseases patients. These agents are effective, however, their long-term safety is still questionable. Objective: We aimed to assess the long-term efficacy and safety of two anti-TNFα therapies. Methods: In our retrospective study, we reviewed medical records via the administration system of the First Department of Medicine, University of Szeged. Female and male patients, aged between 18–65 years who received anti-TNFα therapy between 2010–2019 were enrolled. Results: 102 patients with inflammatory bowel disease were enrolled (Crohn’s disease: 67, ulcerative colitis: 35). The first anti-TNFα therapy was introduced after an average 7.84 and 9.86 years from diagnosis of Crohn’s disease and ulcerative colitis. The first treatment period lasted for 2.64 years; 50% of patients receiving IFX and 46% of patients receiving ADA were in remission at the end of the period. The second treatment period lasted for 4.67 years, 36% of IFX-treated patients and 40% of ADA-treated patients were in remission at the end of the period. 13% and 18% of patients treated by IFX and 4% and 3% of patients treated by ADA experienced infusion reaction during the first and the second treatment period. Primary non-response and loss of response rates were 4% and 10.5% (IFX) and 11.5% and 19% (ADA) during the first treatment period. These rates were 9% and 18% (IFX) and 23% and 10% (ADA) during the second treatment period. Conclusion: Our study confirmed the long-term efficacy and safety of the anti-TNFα therapies. Loss of response rate is lower in our population compared to the literature. Orv Hetil. 2020; 161(47): 1989–1994.

Abstract Background Vedolizumab (VDZ) has demonstrated remission in ulcerative colitis (UC) and Crohn’s disease (CD), but its impact on patient (pt) fatigue is not well understood. Herein we report interim fatigue analysis data from a Belgian registry of VDZ-treated pts. Methods Ad-hoc analysis from the prospective observational Belgian VDZ registry (started, November 2016; data cutoff, February 2019), a sub-study of the European VDZ post-authorization safety study (ENcePP EUPAS6469) included pts aged ≥18 years with UC or CD with ongoing VDZ intravenous therapy (≥2 weeks) at recruitment. At baseline (recruitment) and every 6 months, physicians collected data (follow-up was 3 years or 1 year after last dose if VDZ was discontinued [whichever occurred first] and pts completed the 13-Item Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) scale. Clinical remission was defined as Harvey-Bradshaw Index (HBI) score <5 for CD, and partial Mayo score (pMS) <2 with no individual subscore >1 for UC. This analysis explored the association (using generalized estimating equations) between all available FACIT-F total scores and baseline demographic, clinical, and treatment characteristics in the treatment analysis set (TAS; pts had ≥1 VDZ dose and ≥1 year of follow-up records). Results The registry enrolled 202 VDZ-treated UC and CD pts from 19 Belgian centres. TAS included 141 pts (UC 47, CD 94); median follow-up was 537 days; 140/141 pts had ≥1 FACIT-F score. In the UC and CD groups, respectively, 68% and 42% of pts were male; median (IQR) age at index date was 51 (37–59) and 40 (29–52); and baseline median (IQR) FACIT-F total score was 39 (32–46) and 32 (24–40). Lower FACIT-F score (more fatigue) was associated with higher pMS in UC (p<0.001), and higher HBI score (p=0.01) and having ongoing fistulas at baseline (p=0.01) in CD (Table). Less fatigue was associated with being in remission at baseline in both UC and CD (p<0.01). Being male was associated with less fatigue in the overall population and CD (p<0.01), but not in UC alone. Baseline occurrence of extra intestinal manifestations (EIMs) was associated with more fatigue in the overall group (p=0.037); however few pts (UC 4; CD 8) had EIMs. UC pts had less fatigue than CD pts (p=0.004). From baseline to month 24, the change in median (IQR) FACIT-F total score was -3.0 (-12.0 to 5.0) points for UC and 3.5 (-1.0 to 18.0) for CD. Conclusion These real-world data from a long-term registry study of VDZ-treated pts in Belgium demonstrate that higher pMS and HBI score, active fistulae, and EIM occurrence at baseline may be associated with more fatigue in IBD pts. Pts treated with VDZ had no significant change in FACIT-F total score over 24 months.

Abstract Background Patients with inflammatory bowel diseases (IBD) have experienced changes to the routine management of their conditions during the coronavirus disease (COVID-19) pandemic. The disease as well IBD treatment frequently require immunosuppressant medications, which could increase their risk of infection. The aim of this study was to determine patients’ experience of the health care service, including the restrictions of hospitals visits made in Norway from Mars 12th 2020. Method From June 18 to September 18 2020, all patients at the IBD outpatient clinic at Oslo University Hospital in Norway on biological therapy or other immunosuppressant’s were included. A questionnaire including patients concerns regarding their disease, medical therapy and COVID-19, as well as their health care service needs in follow-up during the COVID-19 pandemic. Results Altogether 506 IBD patients answered a paper-based questionnaire. The mean age was 40.78 (SD 14.71), 289/506 (57%) men, ulcerative colitis 199/506 (39%), Crohn’s disease 307/506 (61%). Sixty-three patients (12.5%) used biological therapy in combination with azathioprine or steroids. Ninety-one (18.2%) were in obligated quarantine with negative test. Five patients (4.9%) tested positive to SARS- CoV-2 of the 98 patients tested, (1.0% of the total sample). One third of the IBD patients perceived they had increased risk for being infected by SARS- CoV-2 because of the immunosuppressive drugs they used. Nonetheless, 496/506 (98.6%) of the patients adhered to continuing their medication. One-hundred and sixty-one (32.3%) voluntarily isolated, and 21/506 (4.2%) was in sick leave being afraid of being infected. Furthermore, 20/506 (4.0%) cancelled their consultation because they were afraid of being infected from SARS- CoV-2 at the hospital. The hospital changed physical consultation to telephone consultation for 75/506 (15.0%) of the patients. Thirty-eight patients (7.6%) reported that they were afraid of going to the hospital because of restrictions due to the COVID-19 pandemic, and 18/506 (3.6%) did not feel safe when at hospital. Approximately half of the IBD patients (219/506) were satisfied with the information provided by physician about medical treatment for IBD and Covid-19 while 398/506 (77.3%) were satisfied with the information from health-care providers about restrictions due to COVID-19. There were no statistical differences between Crohn’s disease and ulcerative colitis. Conclusion IBD patients on biological treatment and immunosuppressives took precautions because of fear of being infected with SARS- CoV-2. At the same time, they adhere to medical treatment regimens and follow-up at the hospital. Most patients were satisfied with the information they received from physicians and other health-care workers. One percent tested positive to SARS-CoV-2.

Summary Background: There is an impression mostly from specialty clinics that patients with inflammatory bowel disease (IBD) have an increased risk of venous thromboembolic disorders. Our aim was to determine the incidence of deep venous thrombosis (DVT) and pulmonary embolism (PE) from a population-based database of IBD patients and, to compare the incidence rates to that of an age, gender and geographically matched population control group. Methods: IBD patients identified from the administrative claims data of the universal provincial insurance plan of Manitoba were matched 1:10 to randomly selected members of the general population without IBD by year, age, gender, and postal area of residence using Manitoba Health’s population registry. The incidence of hospitalization for DVT and PE was calculated from hospital discharge abstracts using ICD-9-CM codes 451.1, 453.x for DVT and 415.1x for PE. Rates were calculated based on person-years of follow-up for 1984-1997. Comparisons to the population cohort yielded age-adjusted incidence rate ratios (IRR). Rates were calculated based on person-years of follow-up (Crohn’s disease = 21,340, ulcerative colitis = 19,665) for 1984-1997. Results: In Crohn’s disease the incidence rate of DVT was 31.4/10,000 person-years and of PE was 10.3/10,000 person-years. In ulcerative colitis the incidence rates were 30.0/10,000 person-years for DVT and 19.8/10,000 person-years for PE. The IRR was 4.7 (95% CI, 3.5-6.3) for DVT and 2.9 (1.8-4.7) for PE in Crohn’s disease and 2.8 (2.1-3.7) for DVT and 3.6 (2.5-5.2) for PE, in ulcerative colitis. There were no gender differences for IRR. The highest rates of DVT and PE were seen among patients over 60 years old; however the highest IRR for these events were among patients less than 40 years. Conclusion: IBD patients have a threefold increased risk of developing DVT or PE.

Background and Aims: Appendectomy is a common surgical procedure, but no overview of the long-term consequences exists. Our aim was to systematically review the long-term complications of appendectomy for acute appendicitis. Materials and Methods: This systematic review was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A protocol was registered on PROSPERO (CRD42017064662). The databases PubMed and EMBASE were searched for original reports on appendectomy with n ≥ 500 and follow-up >30 days. The surgical outcomes were ileus and incisional hernia; other outcomes were inflammatory bowel disease, cancer, fertility, and mortality. Results: We included 37 studies. The pooled estimate of the ileus prevalence was 1.0% over a follow-up period of 4.6 (range, 0.5–15) years. Regarding incisional hernia, we found a pooled estimate of 0.7% prevalence within a follow-up period of 6.5 (range, 1.9–10) years. Ulcerative colitis had a pooled estimate of 0.15% prevalence in the appendectomy group and 0.19% in controls. The opposite pattern was found regarding Crohn’s disease with a pooled estimate of 0.20% prevalence in the appendectomy group and 0.12% in controls. No clear pattern was found regarding most of the examined cancers in appendectomy groups compared with background populations. Pregnancy rates increased after appendicitis compared with controls in most studies. Mortality was low after appendectomy. Conclusion: Appendectomy had a low prevalence of long-term surgical complications. We did not find any significant other long-term complications, though the prevalence of Crohn’s disease was higher and the prevalence of ulcerative colitis was lower after appendectomy than in controls. Appendectomy did not impair fertility.

Abstract Background The approved maintenance regimens for ustekinumab in Crohn’s disease [CD] are 90 mg every 8 or 12 weeks. Some patients will respond partially to ustekinumab or will experience a secondary loss of response. It remains poorly known if these patients may benefit from shortening the interval between injections. Methods All patients with active CD, as defined by Harvey–Bradshaw score ≥ 4 and one objective sign of inflammation [C-reactive protein > 5 mg/L and/or faecal calprotectin > 250 µg/g and/or radiological and/or endoscopic evidence of disease activity] who required ustekinumab dose escalation to 90 mg every 4 weeks for loss of response or incomplete response to ustekinumab 90 mg every 8 weeks were included in this retrospective multicentre cohort study. Results One hundred patients, with a median age of 35 years [interquartile range, 28–49] and median disease duration of 12 [7–20] years were included. Dose intensification was performed after a median of 5.0 [2.8–9.0] months of ustekinumab treatment and was associated with corticosteroids and immunosuppressants in respectively 29% and 27% of cases. Short-term clinical response and clinical remission were observed in respectively 61% and 31% after a median of 2.4 [1.3–3.0] months. After a median follow-up of 8.2 [5.6–12.4] months, 61% of patients were still treated with ustekinumab, and 26% were in steroid-free clinical remission. Among the 39 patients with colonoscopy during follow-up, 14 achieved endoscopic remission [no ulcers]. At the end of follow-up, 27% of patients were hospitalized, and 19% underwent intestinal resection surgery. Adverse events were reported in 12% of patients, including five serious adverse events. Conclusion In this multicentre study, two-thirds of patients recaptured response following treatment intensification with ustekinumab 90 mg every 4 weeks.

<b><i>Background:</i></b> Intestinal ultrasound is emerging as a non-invasive tool for monitoring disease activity in inflammatory bowel disease patients due to its low cost, excellent safety profile, and availability. Herein, we comprehensively review the role of intestinal ultrasound in the management of these patients. <b><i>Summary:</i></b> Intestinal ultrasound has a good accuracy in the diagnosis of Crohn’s disease, as well as in the assessment of disease activity, extent, and evaluating disease-related complications, namely strictures, fistulae, and abscesses. Even though not fully validated, several scores have been developed to assess disease activity using ultrasound. Importantly, intestinal ultrasound can also be used to assess response to treatment. Changes in ultrasonographic parameters are observed as early as 4 weeks after treatment initiation and persist during short- and long-term follow-up. Additionally, Crohn’s disease patients with no ultrasound improvement seem to be at a higher risk of therapy intensification, need for steroids, hospitalisation, or even surgery. Similarly to Crohn’s disease, intestinal ultrasound has a good performance in the diagnosis, activity, and disease extent assessment in ulcerative colitis patients. In fact, in patients with severe acute colitis, higher bowel wall thickness at admission is associated with the need for salvage therapy and the absence of a significant decrease in this parameter may predict the need for colectomy. Short-term data also evidence the role of intestinal ultrasound in evaluating therapy response, with ultrasound changes observed after 2 weeks of treatment and significant improvement after 12 weeks of follow-up in ulcerative colitis. <b><i>Key Messages:</i></b> Intestinal ultrasound is a valuable tool to assess disease activity and complications, and to monitor response to therapy. Even though longer prospective data are warranted, intestinal ultrasound may lead to a change in the paradigm of inflammatory bowel disease management as it can be used in a point-of-care setting, enabling earlier intervention if needed.
