High serum levels of ustekinumab are associated with better clinical outcomes during maintenance treatment for inflammatory bowel disease.

Background: Ustekinumab (UST) is an effective treatment option in Crohn's disease (CD) and ulcerative colitis (UC). However, it still remains unclear if therapeutic drug monitoring could be helpful to guide clinicians. Objectives: The aim of our study was to analyze the relationship between UST through levels (USTTL) and clinical outcomes in real-world inflammatory bowel disease (IBD) patients. Design: We performed a unicentric retrospective study including patients with IBD under UST treatment with at least one level determination. Methods: The following variables were analyzed at the initiation of UST and at each USTTL measurement: clinical response and remission using the Harvey-Bradshaw Index (HBI) for CD and the Partial Mayo Score (pMayo) for UC; biochemical response and remission using fecal calprotectin and C-reactive protein, among others. Two periods were considered: P1 (time between induction and the first determination of USTTL) and P2 (time between USTTL1 and the second determination of USTTL). Results: We included 125 patients, 117 with CD. In P1, 62.4% of patients were on subcutaneous maintenance, and the median USTTL1 was 3.1 µg/mL (1.6-5.3). In 44.8% of CD patients (48/117), clinical remission was achieved, with USTTL1 significantly higher than those who did not achieve remission (3.7 µg/mL (2.3-5.4) vs 2.3 µg/mL (1.1-5.2); p = 0.04). In the 46 patients with two determinations, statistically significant differences were found between variables in P2 versus P1: clinical remission (73.9% vs 21.7%; p = 0.001); USTTL (7.2 µg/mL (4.7-11.7) vs 3.4 µg/mL (1.9-6.4); p < 0.001), HBI (4 (4-4.3) vs 8 (4-9); p < 0.001), pMayo (1 (1-3.3) vs 4.5 (3-5); p = 0.042), and corticosteroid use (26.1% vs 41.3%; p = 0.024). Receiver-Operating-Characteristic (ROC) curves were calculated for clinical remission in P2, with USTTL cutoff value of 6.34 µg/mL for clinical remission and a high rate of intensified patients (98%). Conclusion: High serum levels of UST were associated with clinical remission during treatment for IBD under intensification treatment, with a cutoff point of 6.3 µg/mL.

Severe outbreak of ulcerative colitis and cerebral neoplasia. Difficult management in COVID time.

A 61-year-old male diabetic patient, diagnosed with ulcerative colitis (UC) 30 years ago, currently under treatment with mesalazine is presented. He was admitted to the emergency department due to a severe outbreak of UC, with 15 depositions daily, rectal bleeding and poor general condition. A brain CT-scan was carried out in the emergency department due to a sudden self-limited aphasia. A left frontal lesion of 45x38 mms with a prominent perilesional edema and with a displacement of the midline was reported. This was believed to be a meningioma (figure 1A). Urgent neurosurgery was not performed, prioritizing the severe flare-up UC. Based on this, full-dose metilprednisolone was administered.

Switch to subcutaneous infliximab during the SARS-CoV-2 pandemic: preliminary results.

A new subcutaneous formulation of the infliximab biosimilar CT-P13 has recently been developed for the treatment of inflammatory bowel disease (IBD), providing response rates similar to intravenous treatment. The use of this new formulation was requested, in an effort to limit patient attendance at intravenous infusion centers and to maintain biological treatment during the COVID-19 pandemic. The objective of this observational, retrospective and descriptive study was to assess CT-P13 efficacy and safety after switching from intravenous to a subcutaneous formulation in patients with IBD receiving maintenance therapy. This article shows preliminary results after six months of follow-up.

Comparison of the Mayo Endoscopy Score and the Ulcerative Colitis Endoscopy Index of Severity and the Ulcerative Colitis Colonoscopy Index of Severity.

Background and study aims: Endoscopy plays an essential role in managing patients with ulcerative colitis (UC), as it allows us to visualize and assess the severity of the disease. As such assessments are not always objective, different scores have been devised to standardize the findings. The main aim of this study was to assess the interobserver variability between the Mayo Endoscopy Score (MES), Ulcerative Colitis Endoscopy Index of Severity (UCEIS) and Ulcerative Colitis Colonoscopy Index of Severity (UCCIS) analyzing the severity of the endoscopic lesions in patients with ulcerative colitis. Patients and methods: This was a single-cohort observational study in which a colonoscopy was carried out on patients with UC, as normal clinical practice, and a video was recorded. The results from the video were classified according to the MES, UCEIS and UCCIS by three endoscopic specialists independently, and they were compared to each other. The Mayo Endoscopy Score (MES) was used to assess the clinical situation of the patient. The therapeutic impact was analyzed after colonoscopy was carried out. Results: Sixty-seven patients were included in the study. The average age was 51 (SD ±â€Š16.7) and the average MES was 3.07 (SD ±â€Š2.54). The weighted Kappa index between endoscopists A and B for the MES was 0.8; between A and C 0.52; and between B and C 0.49. The intraclass correlation coefficient for UCEIS was 0.92 among the three endoscopists (CI 95 %: 0.83-0.96) and 0.96 for UCCIS among the three endoscopists (CI 95 % 0.94-0.97). A change in treatment for 34.3 % of the patients was implemented on seeing the results of the colonoscopy. Conclusions: There was an adequate, but not perfect, correlation between the different endoscopists for MES, UCEIS, UCCIS. This was higher with the last two scores. Thus, there is still some subjectivity to be minimized through special training, on assessing the seriousness of the endoscopic lesions in patients with UC.

Views of patients with inflammatory bowel disease during the COVID-19 pandemic: ACCU survey results.

INTRODUCTION AND OBJECTIVES: the SARS-COV-2 pandemic has forced a substantial change in the care of patients with digestive pathologies, especially for inflammatory bowel disease (IBD) patients taking immunosuppessive medications. In this regard, some national and international guidelines have indicated the standards to be taken into account. However, few studies have evaluated how patients have dealt with this infection. Therefore, this study was performed with the aim to determine how the SARS-COV-2 pandemic has affected our IBD patients. MATERIAL AND METHODS: an online survey was performed among the members (295) of the Association of Crohn's Disease and Ulcerative Colitis (ACCU), which consisted of 19 questions. Finally, it was completed by 168 patients. RESULTS: fifty-eight per cent of cases were female, 63.7 % had Crohn's disease (CD) and 53 % received biologic therapy. Five per cent were infected by SARS-CoV-2 and were male. The main concern of the patients was the fear of acquiring the infection (80.9 %). More than 90 % continued their treatments and half of the patients worked from home during the pandemic period. CONCLUSIONS: the perspective of the patients is necessary to achieve an adequate management and evolution of the disease. More studies are needed to assess the impact that exceptional situations, such as the COVID-19 pandemic, may have on IBD patients in order to improve adherence and control of the disease.

Índice de Mayo Endoscópico e Índice de Severidad Endoscópica de la Colitis Ulcerosa: ¿son igual de válidos? / No disponible

INTRODUCCIÓN: la endoscopia tiene un papel fundamental en el manejo de los pacientes con colitis ulcerosa (CU), ya que permite la visualización y evaluación de la gravedad de la enfermedad. No obstante, dicha evaluación no es siempre algo objetivo, por lo que se han desarrollado diferentes escalas que pretenden homogeneizar los hallazgos. Objetico: el objetivo del estudio fue evaluar la variabilidad interobservador entre el Índice de Mayo Endoscópico (IME) y el Índice de Severidad Endoscópica de la Colitis Ulcerosa (UCEIS), al analizar la gravedad de las lesiones endoscópicas en pacientes con CU. El objetivo secundario fue analizar si la preparación catártica afectaba al grado de concordancia entre los endoscopistas. MATERIAL Y MÉTODOS: se trata de un estudio observacional comparativo de una única cohorte a la cual se realiza una colonoscopia bajo guía de práctica clínica habitual a pacientes con CU y se estadifica según el IME y el UCEIS por tres endoscopistas expertos. Para valorar el grado de correlación interobservador se utilizaron el índice de Kappa para el IME y el coeficiente de correlación intraclase para el UCEIS. Se incluyeron 67 pacientes, con edad media de 51 años (DE ± 16,7) e índice de Mayo clínico medio de 3,07 (DE ± 2,54). RESULTADOS: el índice de Kappa ponderado entre los endoscopistas A y B para el IME fue de 0,8; entre el A y el C, de 0,52; y entre el B y el C, de 0,49. Para el UCEIS, el coeficiente de correlación intraclase fue del 0,922 entre los tres endoscopistas (IC 95 %: 0,832-0,959). Se encontró una mejor correlación interobservador cuando la preparación catártica era ≥ 8 según la escala de Boston. CONCLUSIÓN: existe, por tanto, una superior correlación entre los diferentes endoscopistas para el UCEIS que para el IME, por lo que debería ser considerado como el mejor índice a utilizar en la práctica clínica. Una buena preparación catártica es importante para mejorar la correlación interobservador

Neuroendocrine tumors rarely occur in the esophagus because the neuroendocrine system is not well developed in the esophagus. The case of a neuroendocrine esophageal tumor developed in a patient with Barret's esophagus is presented. It was successfully trated by endoscopy.

Index of the Mayo Endoscopy and Ulcerative Colitis Endoscopy Index of Severity: are they equally valid?

INTRODUCTION: endoscopy plays an essential role in the management of patients with ulcerative colitis (UC), as it allows us to visualize and assess the severity of the disease. Different scores have been devised to standardize the findings because such assessments are not always objective. AIMS: the aim of this study was to assess the interobserver variability between the Index of Mayo Endoscopy (IME) and the Ulcerative Colitis Endoscopy Index of Severity (UCEIS), analyzing the severity of the endoscopic lesions in patients with UC. The secondary aim was to analyze if the cathartic preparation affected the degree of concordance amongst the endoscopists. MATERIAL AND METHODS: this was a single-cohort observational, comparative study in which a colonoscopy was performed in patients with UC, as the normal clinical practice. The results were classified according to the IME and the UCEIS by three endoscopic specialists. In order to assess the degree of interobserver correlation, the Kappa index for IME was used and the intraclass correlation coefficient was used for UCEIS. RESULTS: sixty-seven patients were included in the study. The average age was 51 (SD ± 16.7) and the average Mayo Clinic index was 3.07 (SD ± 2.54). The weighted Kappa index between endoscopists A and B for the IME was 0.8, 0.52 between A and C and 0.49 between B and C. The intraclass correlation coefficient for UCEIS was 0.922 between the three endoscopists (95 % CI: 0.832-0.959). A better interobserver correlation was found when the cathartic preparation was ≥ 8 based on the Boston Scale. CONCLUSIONS: there was a higher correlation between the different endoscopists for the UCEIS than for the IME. Thus, this should be considered to be the best index to use in the clinical practice. A good cleansing preparation is important to improve the interobserver correlation.

Long-term follow up after switching from original infliximab to an infliximab biosimilar: real-world data.

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.
