Efficacy and safety of biological treatment for inflammatory bowel disease in elderly patients: Results from a GETECCU cohort.

INTRODUCTION: Biological therapies used for the treatment of inflammatory bowel disease (IBD) have shown to be effective and safe, although these results were obtained from studies involving mostly a young population, who are generally included in clinical trials. The aim of our study was to determine the efficacy and safety of the different biological treatments in the elderly population. METHODS: Multicenter study was carried out in the GETECCU group. Patients diagnosed with IBD and aged over 65 years at the time of initiating biological therapy (infliximab, adalimumab, golimumab, ustekinumab or vedolizumab) were retrospectively included. Among the patients included, clinical response was assessed after drug induction (12 weeks of treatment) and at 52 weeks. Patients' colonoscopy data in week 52 were assessment, where available. Regarding complications, development of oncological events during follow-up and infectious processes occurring during biological treatment were collected (excluding bowel infection by cytomegalovirus). RESULTS: A total of 1090 patients were included. After induction, at approximately 12-14 weeks of treatment, 419 patients (39.6%) were in clinical remission, 502 patients (47.4%) had responded without remission and 137 patients (12.9%) had no response. At 52 weeks of treatment 442 patients (57.1%) had achieved clinical remission, 249 patients had responded without remission (32.2%) and 53 patients had no response to the treatment (6.8%). Before 52 weeks, 129 patients (14.8%) had discontinued treatment due to inefficacy, this being significantly higher (p<0.0001) for Golimumab - 9 patients (37.5%) - compared to the other biological treatments analyzed. With respect to tumor development, an oncological event was observed in 74 patients (6.9%): 30 patients (8%) on infliximab, 23 (7.14%) on adalimumab, 3 (11.1%) on golimumab, 10 (6.4%) on ustekinumab, and 8 (3.8%) on vedolizumab. The incidence was significantly lower (p=0.04) for the vedolizumab group compared to other treatments. As regards infections, these occurred in 160 patients during treatment (14.9%), with no differences between the different biologicals used (p=0.61): 61 patients (19.4%) on infliximab, 39 (12.5%) on adalimumab, 5 (17.8%) on golimumab, 22 (14.1%) on ustekinumab, and 34 (16.5%) on vedolizumab. CONCLUSIONS: Biological drug therapies have response rates in elderly patients similar to those described in the general population, Golimumab was the drug that was discontinued most frequently due to inefficacy. In our experience, tumor development was more frequent in patients who used anti-TNF therapies compared to other targets, although its incidence was generally low and that this is in line with younger patients based on previous literature.

Real-World Evidence of Tofacinitib in Ulcerative Colitis: Short-Term and Long-Term Effectiveness and Safety.

INTRODUCTION: The objective of this study was to assess the durability, short-term and long-term effectiveness, and safety of tofacitinib in ulcerative colitis (UC) in clinical practice. METHODS: This is a retrospective multicenter study including patients with UC who had received the first tofacitinib dose at least 8 weeks before the inclusion. Clinical effectiveness was based on partial Mayo score. RESULTS: A total of 408 patients were included. Of them, 184 (45%) withdrew tofacitinib during follow-up (mean = 18 months). The probability of maintaining tofacitinib was 67% at 6 m, 58% at 12 m, and 49% at 24 m. The main reason for tofacitinib withdrawal was primary nonresponse (44%). Older age at the start of tofacitinib and a higher severity of clinical activity were associated with tofacitinib withdrawal. The proportion of patients in remission was 38% at week 4, 45% at week 8, and 47% at week 16. Having moderate-to-severe vs mild disease activity at baseline and older age at tofacitinib start were associated with a lower and higher likelihood of remission at week 8, respectively. Of 171 patients in remission at week 8, 83 (49%) relapsed. The probability of maintaining response was 66% at 6 m and 54% at 12 m. There were 93 adverse events related to tofacitinib treatment (including 2 pulmonary thromboembolisms [in patients with risk factors] and 2 peripheral vascular thrombosis), and 29 led to tofacitinib discontinuation. DISCUSSION: Tofacitinib is effective in both short-term and long-term in patients with UC. The safety profile is similar to that previously reported.

Impact of Clostridioides difficile infection in patients admitted with ulcerative colitis.

BACKGROUND: Patients with ulcerative colitis (UC) are at increased risk of Clostridioides difficile infection (CDI), which is the principal causative agent of nosocomial diarrhoea in western countries. This has been related to complications such as need of colectomy and mortality among these patients. The aim of this study was to assess the incidence and impact of CDI in patients hospitalised with UC. METHODS: Case-control retrospective study including patients admitted due to a UC flare from January 2000 to September 2018. Porpensity score matching (PSM) was performed to minimise selection bias taking into account the small number of cases compared to controls. RESULTS: 339 patients were included; CDI in 35 (10.3%) patients. After PSM, 35 (33.33%) cases and 70 (66.67%) controls were analysed. Patients with CDI presented higher rates of readmission (52.9% vs. 21.4%, p = .001), increased mortality within the first 3 months post-discharge (5.9% vs. 0%, p = .042) and increased need of therapy intensification in the first year after admission (20.7% vs. 12.5%, p = .001). No risk factors for CDI were identified. Multivariable cox regression showed that treatment with 5-aminosalycilates at baseline (HR 0.42, 95% CI 0.18-0.92) and albumin <3.5 g/dL (HR 3.11, 95% CI 1.21-8.03) were associated with worse outcomes. CONCLUSIONS: CDI is a prevalent situation in hospitalised UC patients related to higher mortality within the first 3 months after the infection, need for therapy intensification within the first year and readmission. Our results underline the importance of CDI detection in patients with a flare of UC.

Mesalazine induced interstitial pneumonitis in the COVID era.

Mesalazine is the most widely used aminosalicylate for induction and maintenance of remission in patients with mild-to-moderate ulcerative colitis (UC). Drug-induced hypersensitivity pneumonitis is considered very rare (<1/10.000 patients). Due to its rarity and the scarce cases reported, mesalazine-induced lung injury needs to be highly suspected in a patient with onset of respiratory symptoms and UC under treatment with salicylates. It should make the clinician formulate a differential diagnosis that includes not only infections (tuberculosis, bacterial...) or the inflammatory bowel disease itself, but also the current coronavirus disease 2019 (COVID-19) since their clinical and radiological manifestations may be very similar.

Granulocyte and monocyte apheresis in inflammatory bowel disease: The patients' point of view.

BACKGROUND: Granulocyte and monocyte apheresis is the main non-pharmacological treatment for inflammatory bowel disease (IBD), but we do not know how well accepted it is by patients in our setting. AIM: To determine how granulocyte and monocyte apheresis is perceived by patients in clinical practice in Spain. METHODS: Outpatients treated with granulocyte and monocyte apheresis in five IBD Units in Spain were asked to fill in a 14-item questionnaire. RESULTS: Fifty-two patients completed the questionnaire (88% ulcerative colitis, 12% Crohn's disease; 44% female; age 35 years [IQR 23-51]). Granulocyte and monocyte apheresis was generally well tolerated and well accepted. Very few of the participants regarded the length of the sessions as a limitation. The gastrointestinal symptoms, however, were a frequent concern, both in terms of attending to receive treatment and during the sessions. Overall, 44% were satisfied with the treatment effectiveness. Sixty percent (60%) claimed to be satisfied with the therapy overall, but this was influenced by the patients' clinical response to the therapy. Eighty-two percent (82%) of participants said they would agree to be treated with this technique again in the future, regardless of the response to the treatment. CONCLUSIONS: Granulocyte and monocyte apheresis is well tolerated and accepted by patients with IBD. Although we found no significant differences according to type of IBD or apheresis regimen, patient perception was affected by clinical effectiveness.

Prevalence of iron deficiency without anaemia in inflammatory bowel disease and impact on health-related quality of life. / Prevalencia de déficit de hierro sin anemia en la enfermedad inflamatoria intestinal y su impacto en la calidad de vida.

INTRODUCTION: Iron deficiency without anaemia (IDWA) is commonly found in outpatients with inflammatory bowel disease (IBD) in an even higher proportion than anaemia. However, its true prevalence and possible impact on health-related quality of life (HRQoL) are unknown. The objectives of this study were: to establish the prevalence of IDWA, identify possible associated factors and measure their impact on HRQoL. MATERIAL AND METHODS: 127 patients with IBD in an outpatient setting were consecutively included in an observational, descriptive, cross-sectional study. IDWA was defined as ferritin levels of <100 ng/ml with inflammatory activity or ≤30 ng/ml without it, with transferrin saturation of ≤16%, and with normal haemoglobin levels. HRQoL was assessed using two questionnaires: the IBDQ-9 for symptoms related to IBD and the FACIT-F to measure the presence of fatigue. Fatigue was considered extreme with a score of ≤30 points. RESULTS: The prevalence of IDWA was 37%. Variables associated with its occurrence were female gender (OR=2.9; p=.015) and the presence of inflammatory activity (OR=9.4; p=.001). Patients with IDWA presented HRQoL questionnaires with lower overall scores; decreases of 6.6 (p<.001) and 4.3 (p=.037) points in the IBDQ-9 and the FACIT-F were recorded, respectively. In addition, an increase of 29.4% in the presence of extreme fatigue was observed. CONCLUSION: The prevalence of IDWA is considerable in outpatients with IBD. IDWA is associated with female gender and inflammatory activity. It has a clear negative impact on HRQoL. A more active approach is needed to treat this complication.

Evolution of the incidence of inflammatory bowel disease in Southern Spain.

BACKGROUND: The incidence of inflammatory bowel disease is increasing in Europe and in Spain. However, there is no recent data from Southern Spain. OBJECTIVES: To determine the evolution of the hospital incidence of inflammatory bowel disease in Southern Spain. MATERIAL AND METHODS: A retrospective study was performed in two hospitals in Southern Spain. Data was collected from inflammatory bowel disease patients, divided into two periods (1995-2000 and 2001-2014) and compared. The reference population from both areas was 1,011,555 inhabitants. RESULTS: A total of 430 patients were registered during the first period (1995-2000); 50% (215) had Crohn's disease that resulted in a cumulative incidence rate of 7.08 cases/100,000 inhabitants per year. The overall inflammatory bowel disease incidence was 3.54 cases/100,000 inhabitants per year. During the second period (2001-2014), 2,089 patients were collected; 51.7% had ulcerative colitis (1,081). The rate of cumulative incidence of inflammatory bowel disease was 14.7 cases/100,000 inhabitants per year (7.6 cases of ulcerative colitis/100,000 inhabitants/year and 7.1 cases of Crohn´s disease/100,000 inhabitants/year). CONCLUSIONS: The incidence of inflammatory bowel disease in Southern Spain has doubled in the last decade and is similar to that of the rest of the country and Europe.

Evolution after switching to biosimilar infliximab in inflammatory bowel disease patients in clinical remission. / Evolución tras el intercambio a infliximab biosimilar en pacientes con enfermedad inflamatoria intestinal en remisión clínica.

BACKGROUND AND AIM: The biosimilar of infliximab (CT-P13) has been approved for the same indications held by the infliximab reference product (Remicade®); however, there are few clinical data on switching in inflammatory bowel disease (IBD). The aim of this study was to assess the efficacy, safety, bioavailability profile and factors associated with relapse after switching to biosimilar infliximab in IBD patients in clinical remission. MATERIAL AND METHOD: Observational study with IBD patients treated with Remicade® for at least 6 months and in clinical remission for at least 3 months who switched to infliximab biosimilar. The incidence of relapse, adverse effects and possible changes in drug bioavailability (trough level and antidrug antibodies) were evaluated. RESULTS: Thirty six patients were included (63.9% CD) with a mean follow-up of 8.4 months (SD±3.5). The 13.9% had clinical relapse. The longer clinical remission time before switching (HR=0.54, 95% CI=0.29-0.98, P=.04) and detectable infliximab levels at the time of switching (HR=0.03, 95% CI=0.001-0.89, P=.04) were associated with a lower risk of relapse. No differences were found between infliximab levels at the time of switching and at weeks 8 and 16 (P=.94); 8.3% of the patients had some adverse event, requiring the suspension of biosimilar in one patient for severe pneumonia. CONCLUSION: Switching to biosimilar infliximab in a real-life cohort of IBD patients in clinical remission did not have a significant impact on short-term clinical outcomes. The factors associated with relapse were similar to those expected in patients continuing with Remicade®.

Initial experience with golimumab in clinical practice for ulcerative colitis.

BACKGROUND: Golimumab is a TNF-blocking agent indicated as a second-line therapy in ulcerative colitis. PURPOSE: To research the effectiveness and safety of golimumab in patients with ulcerative colitis in clinical practice. METHODS: Retrospective study of the effectiveness and safety of golimumab in patients with ulcerative colitis. All patients received golimumab 200 mg subcutaneously at week 0, and golimumab 100 mg subcutaneously at week 2. After the induction treatment, each patient received 50 mg sc. every 4 weeks in patients with body weight less than 80 kg, and 100 mg every 4 weeks in patients with body weight greater than or equal to 80 kg. RESULTS: Study of a group of 23 ulcerative colitis patients, 7 of whom were naive to any anti-TNF therapy, and 16 patients who had previously been treated with an anti-TNF agent other than golimumab (non-naive patients). The average treatment time with golimumab was 14.3 weeks. Globally, withdrawal of corticosteroids was observed in 74% of cases. Clinical response was observed in 85.5% of patients who had not received biological treatment previously, and in patients who had previously received biological treatment the response rate was 75%. CONCLUSIONS: In this short study, golimumab seems to be an alternative treatment in naive and non-naive anti-TNF ulcerative colitis patients. It is also a safe therapy, given that there were no adverse effects in the patients studied.

Can we predict the high-risk patient?

BACKGROUND: While therapeutic strategies able to change the natural history of inflammatory bowel diseases (IBD) are being developed, factors predicting aggressive disease are needed to be able to choose the appropriate therapeutic strategy for the individual patient based on the risk/benefit ratio. The aim of this review is to focus on the tools assisting the clinician in routine practice regarding the prediction of disease evolution. METHODS: A literature review was performed, which was mainly based on PubMed search, using the following terms: Crohn's disease, ulcerative colitis, inflammatory bowel disease, genetics, serology, biomarkers, endoscopy, C-reactive protein, faecal calprotectin, disease evolution and complications. RESULTS: For the prediction of disease evolution, clinical characteristics, particularly disease location and behaviour, are probably currently the most useful. In addition, a series of biomarkers, including genetic, serological and inflammatory markers, as well as characteristics of endoscopic lesions may have an added value. CONCLUSIONS: Simple clinical, biological and endoscopic tools may help the clinician in predicting disease evolution in IBD. However, these tools are still insufficient, and prospective evaluation of new genetic and biological markers are needed.

Role of endoscopy, cross-sectional imaging and biomarkers in Crohn's disease monitoring.

Crohn's disease is characterised by recurrent and/or chronic inflammation of the gastrointestinal tract leading to cumulative intestinal tissue damage. Treatment tailoring to try to prevent this tissue damage as well as achieve optimal benefit/risk ratio over the whole disease course is becoming an important aspect of Crohn's disease management. For decades, clinical symptoms have been the main trigger for diagnostic procedures and treatment strategy adaptations. However, the correlation between symptoms and intestinal lesions is only weak. Furthermore, preliminary evidence suggests that a state of remission beyond the simple control of clinical symptoms, and including mucosal healing, may be associated with better disease outcome. Therefore monitoring the disease through the use of endoscopy and cross-sectional imaging is proposed. However, the degree of mucosal or bowel wall healing that needs to be reached to improve disease outcome has not been appropriately studied. Furthermore, owing to their invasive nature and cost, endoscopy and cross-sectional imaging are not optimal tools for the patients or the payers. The use of biomarkers as surrogate markers of intestinal and systemic inflammation might help. Two biomarkers have been most broadly assessed in Crohn's disease: C-reactive protein and faecal calprotectin. These markers correlate significantly with endoscopic lesions, with the risk of relapse and with response to therapy. They could be used to help make decisions about diagnostic procedures and treatment. In particular, with the use of appropriate threshold values, they could determine the need for endoscopic or medical imaging procedures to confirm the disease activity state.

A Comparative Analysis of International Classification Systems to Predict the Risk of Collapse in Single-Level Osteoporotic Vertebral Fractures.

INTRODUCTION: Various classifications for osteoporotic vertebral fractures (OVFs) have been introduced to enhance patient care and facilitate clinical communication. However, there is limited evidence of their effectiveness in predicting vertebral collapse, and very few studies have compared this association across different classification systems. This study aims to investigate the association between OVF categories, according to the most widely used classification systems, and vertebral collapse. PATIENTS AND METHODS: A retrospective single-center study was conducted involving patients diagnosed with acute OVFs at the emergency department of a tertiary-level academic hospital with a minimum follow-up of 6 months. Vertebral fractures were independently classified by two radiologists according to several classification systems, including those proposed by Genant, Sugita, the German Society for Orthopedics and Trauma (DGOU), and the AO Spine. Associations between vertebral collapse and OVF classification systems were analyzed using bivariate and logistic regression analyses. RESULTS: This study included 208 patients (82.7% females; mean age of 72.6 ± 9.2 years). The median follow-up time was 15 months, with L1 being the most common fracture site (47.6%). The most frequent OVF types observed, according to Genant's morphological, Genant's quantitative, Sugita 's, DGOU's, and AO Spine's classifications, were biconcave (50%), grade 0.5 (47.6%), bow-shaped (61.5%), OF2 (74%), and A1 (61.5%), respectively. All classifications, except for Genant's quantitative system, were significantly associated with vertebral collapse in bivariate analyses. Logistic regression analyses showed a significant association (p = 0.002) between the AO Spine classification and vertebral collapse, with 85.7% of A4 fractures developing collapse on follow-up. CONCLUSIONS: The AO Spine classification showed the highest predictive capacity for vertebral collapse. Specifically, A4 fracture types showed a very high risk of vertebral collapse, confirming the need for non-conservative management of these fractures. Further multicentric and prospective studies are warranted to confirm these findings.

Clinical and treatment outcomes of a second subcutaneous or intravenous anti-TNF in patients with ulcerative colitis treated with two consecutive anti-TNF agents: data from the ENEIDA registry.

Background: Infliximab seems to be the most efficacious of the three available anti-TNF agents for ulcerative colitis (UC) but little is known when it is used as the second anti-TNF. Objectives: To compare the clinical and treatment outcomes of a second subcutaneous or intravenous anti-TNF in UC patients. Design: Retrospective observational study. Methods: Patients from the ENEIDA registry treated consecutively with infliximab and a subcutaneous anti-TNF (or vice versa), naïve to other biological agents, were identified and grouped according to the administration route of the first anti-TNF into IVi (intravenous initially) or SCi (subcutaneous initially). Results: Overall, 473 UC patients were included (330 IVi and 143 SCi). Clinical response at week 14 was 42.7% and 48.3% in the IVi and SCi groups (non-statistically significant), respectively. Clinical remission rates at week 52 were 32.8% and 31.4% in the IVi and SCi groups (nonsignificant differences), respectively. A propensity-matched score analysis showed a higher clinical response rate at week 14 in the SCi group and higher treatment persistence in the IVi group. Regarding long-term outcomes, dose escalation and discontinuation due to the primary failure of the first anti-TNF and more severe disease activity at the beginning of the second anti-TNF were inversely associated with clinical remission. Conclusion: The use of a second anti-TNF for UC seems to be reasonable in terms of efficacy, although it is particularly reduced in the case of the primary failure of the first anti-TNF. Whether the second anti-TNF is infliximab or subcutaneous does not seem to affect efficacy.

Effectiveness and safety of azathioprine for inflammatory pouch disorders: results from the RESERVO study of GETECCU.

Background: The usefulness of thiopurines has been poorly explored in pouchitis and other pouch disorders. Objective: To evaluate the effectiveness and safety of azathioprine as maintenance therapy in inflammatory pouch disorders. Design: This was a retrospective and multicentre study. Methods: We included patients diagnosed with inflammatory pouch disorders treated with azathioprine in monotherapy. Effectiveness was evaluated at 1 year and in the long term based on normalization of stool frequency, absence of pain, faecal urgency or fistula discharge (clinical remission), or any improvement in these symptoms (clinical response). Endoscopic response was evaluated using the Pouchitis Disease Activity Index (PDAI). Results: In all, 63 patients were included [54% males; median age, 49 (28-77) years]. The therapy was used to treat pouchitis (n = 37) or Crohn's disease of the pouch (n = 26). The rate of clinical response, remission and non-response at 12 months were 52%, 30% and 18%, respectively. After a median follow-up of 23 months (interquartile range 11-55), 19 patients (30%) were in clinical remission, and 45 (66%) stopped therapy. Endoscopic changes were evaluated in 19 cases. PDAI score decreased from 3 (range 2-4) to 1 (range 0-3). In all, 21 patients (33%) presented adverse events and 16 (25%) needed to stop therapy. Conclusion: Azathioprine may be effective in the long term for the treatment of inflammatory pouch disorders and could be included as a therapeutic option.

Benefits of Paediatric to Adult Transition Programme in Inflammatory Bowel Disease: The BUTTERFLY Study of GETECCU and SEGHNP.

(1) Background: Transition is a planned movement of paediatric patients to adult healthcare systems, and its implementation is not yet established in all inflammatory bowel disease (IBD) units. The aim of the study was to evaluate the impact of transition on IBD outcomes. (2) Methods: Multicentre, retrospective and observational study of IBD paediatric patients transferred to an adult IBD unit between 2017-2020. Two groups were compared: transition (≥1 joint visit involving the gastroenterologist, the paediatrician, a programme coordinator, the parents and the patient) and no-transition. Outcomes within one year after transfer were analysed. The main variable was poor clinical outcome (IBD flare, hospitalisation, surgery or any change in the treatment because of a flare). Predictive factors of poor clinical outcome were identified with multivariable analysis. (3) Results: A total of 278 patients from 34 Spanish hospitals were included. One hundred eighty-five patients (67%) from twenty-two hospitals (65%) performed a structured transition. Eighty-nine patients had poor clinical outcome at one year after transfer: 27% in the transition and 43% in the no-transition group (p = 0.005). One year after transfer, no-transition patients were more likely to have a flare (36% vs. 22%; p = 0.018) and reported more hospitalisations (10% vs. 3%; p = 0.025). The lack of transition, as well as parameters at transfer, including IBD activity, body mass index < 18.5 and corticosteroid treatment, were associated with poor clinical outcome. One patient in the transition group (0.4%) was lost to follow-up. (4) Conclusion: Transition care programmes improve patients' outcomes after the transfer from paediatric to adult IBD units. Active IBD at transfer impairs outcomes.
