RESUMO
BACKGROUND: Current evidence suggests vedolizumab (VDZ) may be as effective as Infliximab (IFX) in inflammatory bowel disease. It is unknown if proactive therapeutic drug monitoring (PTDM) of IFX may improve these results. METHODS: Case-control study including consecutive patients with primary response to conventional IFX (n = 70), proactive IFX (n = 148), and VDZ (n = 95). PTDM was performed at week 14 and every other infusion, aiming at a trough level between 5 and 10 µg/ml. The primary outcome was fecal calprotectin (Fc) remission (<250 µg/g) at 1 year of treatment. Secondary outcomes included Fc remission at week 14 (proactive IFX/VDZ), clinical remission, treatment discontinuation, hospitalization, and surgery at 1-year of follow-up. RESULTS: Proactive IFX was superior to conventional IFX and VDZ in inducing Fc remission at 1-year (69.4% vs 47.1% vs 37.9%, p = .003 and p < .001). Results remained significant in biologic naïve patients (70.8% vs 44.4% vs 51.4%, p = .001 and p = .043) but comparisons between conventional IFX and VDZ were not significant (p = .265 and p = .664). In multivariate analysis correcting for prior biologic exposure, proactive IFX was more effective than conventional IFX (OR 2.480 95%CI [1.367-4.499], p = .003) and VDZ (OR 3.467 95%CI [1.578-7.617], p = .002) in inducing Fc remission. Amongst secondary outcomes, only clinical remission was significant between proactive IFX and VDZ in the overall cohort (80.4% vs 55.8%, p < .001) and in biologic naïve patients (80.2% vs 62.9%, p = .043). Fc remission at 1-year was associated with better results in most secondary outcomes. CONCLUSION: Proactive IFX was superior to VDZ in inducing Fc remission at 1-year, which was associated with improved clinical outcomes.SUMMARYCurrent evidence suggests that vedolizumab may be as effective as Infliximab in the treatment of patients with inflammatory bowel disease.There have been no studies comparing vedolizumab with proactively optimized Infliximab based on trough levels.We confirm that conventional IFX is as effective as vedolizumab but proactive IFX appears superior to vedolizumab in inducing fecal calprotectin remission.Fecal calprotectin remission associates with better clinical outcomes.

Background: The role of capsule endoscopy in the evaluation of the small bowel is well established, and current guidelines position it as a first-line test in a variety of clinical scenarios. The advent of double-headed capsules further enabled the endoscopic assessment of colonic mucosa and the opportunity for a one-step noninvasive examination of the entire bowel (pan-enteric capsule endoscopy [PCE]). Summary: We reviewed the technical procedure and preparation of patients for PCE, as well as its current clinical applications and future perspectives. In non-stricturing and non-penetrating Crohn's disease affecting the small bowel and colon, PCE monitors disease activity by assessing mucosal healing, a major treatment outcome, with a higher diagnostic yield than cross-sectional imaging or conventional colonoscopy. Also in ulcerative colitis, double-headed capsules have been used to monitor disease activity noninvasively. Currently, validated scoring systems have been specifically devised for these double-headed capsules and permit a standardized assessment of the inflammatory burden. In suspected mid-lower digestive bleeding, some exploratory studies have demonstrated the feasibility and high diagnostic yield of PCE, which may work as a filter indicating which patients may benefit of further invasive procedures, namely, for planned hemostatic procedures. The possibility of using PCE is also discussed in the context of polyposis syndromes with simultaneous involvement of the small intestine and colon. Key Messages: PCE is a feasible, effective, and safe diagnostic procedure to evaluate the small bowel and colon. It has been increasingly explored in the setting of inflammatory bowel diseases and, more recently, in suspected mid-lower digestive bleeding. PCE is expected to reduce the demand for invasive procedures and expand the scope of noninvasive intestinal evaluation in the coming future.
Introdução: O papel da endoscopia por cápsula na avaliação do intestino delgado encontra-se bem estabelecido, e as orientações atuais posicionam-na como um teste de primeira linha numa variedade de cenários clínicos. O advento das cápsulas de dupla câmara permitiu expandir a sua aplicação para a avaliação endoscópica da mucosa do cólon, oferecendo a oportunidade de um exame não invasivo de todo o intestino (endoscopia pan-entérica por cápsula, PCE). Sumário: Procedemos a uma revisão de vários aspectos do procedimento e preparação dos doentes para a PCE, bem como as aplicações clínicas atuais e as perspetivas futuras das cápsulas de dupla câmara. Na doença de Crohn não estenosante e não penetrante localizada ao intestino delgado e cólon, a PCE permite monitorizar a atividade da doença e avaliar a cicatrização da mucosa, um indicador importante da eficácia da terapêutica, com um rendimento de diagnóstico superior aos métodos convencionais, nomeadamente os exames imagiológicos ou a colonoscopia invasiva. Também na colite ulcerosa, as cápsulas de dupla câmara têm sido utilizadas para monitorizar a atividade da doença de forma não invasiva. Existem índices endoscópicos validados e especificamente concebidos para as cápsulas de dupla câmara, que permitem uma avaliação sistematizada e quantificação objetiva da atividade inflamatória. Na suspeita de hemorragia digestiva média ou baixa, alguns estudos exploratórios demonstraram a aplicabilidade e o elevado rendimento diagnóstico da PCE, podendo funcionar como um filtro de modo a permitir indicar quais os doentes que mais irão beneficiar de um procedimento invasivo subsequente, nomeadamente para a realização de procedimentos hemostáticos dirigidos. A possibilidade de utilização da PCE é também discutida no contexto das síndromes de polipose com envolvimento simultâneo do intestino delgado e do cólon. Mensagens-chave: A PCE é um procedimento diagnóstico eficaz e seguro para avaliar diretamente a mucosa do intestino delgado e cólon. A sua aplicação tem vindo a expandir-se no contexto das Doenças Inflamatórias Intestinais e, mais recentemente, na suspeita de hemorragia digestiva média ou baixa. Existe a expectativa de que no futuro próximo possamos assistir a uma redução substancial da demanda por procedimentos endoscópicos invasivos, face à utilização crescente da PCE enquanto método de diagnóstico pan-intestinal não invasivo.
RESUMO
INTRODUCTION: Evidence supporting transmural remission (TR) as a long-term treatment target in Crohn's disease (CD) is still unavailable. Less stringent but more reachable targets such as isolated endoscopic (IER) or radiologic remission (IRR) may also be acceptable options in the long-term. METHODS: Multicenter retrospective study including 404 CD patients evaluated by magnetic resonance enterography and colonoscopy. Five-year rates of hospitalization, surgery, use of steroids, and treatment escalation were compared between patients with TR, IER, IRR, and no remission (NR). RESULTS: 20.8% of CD patients presented TR, 23.3% IER, 13.6% IRR and 42.3% NR. TR was associated with lower risk of hospitalization (odds-ratio [OR] 0.244 [0.111-0.538], p < 0.001), surgery (OR 0.132 [0.030-0.585], p = 0.008), steroid use (OR 0.283 [0.159-0.505], p < 0.001), and treatment escalation (OR 0.088 [0.044-0.176], p < 0.001) compared to no NR. IRR resulted in lower risk of hospitalization (OR 0.333 [0.143-0.777], p = 0.011) and treatment escalation (OR 0.260 [0.125-0.540], p < 0.001), while IER reduced the risk of steroid use (OR 0.442 [0.262-0.745], p = 0.002) and treatment escalation (OR 0.490 [0.259-0.925], p = 0.028) compared to NR. CONCLUSIONS: TR improved clinical outcomes over 5 years of follow-up in CD patients. Distinct but significant benefits were seen with IER and IRR. This suggests that both endoscopic and radiologic remission should be part of the treatment targets of CD.

In this review, we would like to focus on risk stratification and quality indicators of diagnostic upper gastrointestinal endoscopy in the detection and characterization of early gastric cancer. Preparation of the upper gastrointestinal tract with mucolytic agents or simethicone is often overlooked in the west, and this inexpensive step prior to endoscopy can greatly improve the quality of imaging of the upper digestive tract. Risk stratification based on epidemiological features including family history, Helicobacter pylori infection status, and tobacco smoking is often overlooked but may be useful to identify a subgroup of patients at higher risk of developing gastric cancer. Quality indicators of diagnostic upper gastrointestinal endoscopy are now well defined and include: minimal inspection time of 3 min, adequate photographic documentation of upper gastrointestinal landmarks, utilization of advanced endoscopic imaging technology including narrow band imaging and blue laser imaging to detect intestinal metaplasia and characterize early gastric cancer; and standardized biopsy protocols allow for histological evaluation of gastric mucosa and detection of atrophic gastritis and intestinal metaplasia. Finally, endoscopic and histologic classifications such as the Kimura-Takemoto Classification of atrophic gastritis and the OLGA-OLGIM classifications may help stratify patients at a higher risk of developing early gastric cancer.
RESUMO
SARS-CoV-2 infection can present in different clinical forms, most commonly as bilateral pneumonia, but also with pericardial/myocardial involvement. Cardiac involvement in COVID-19 is associated with worse outcomes. The authors report a case of myopericarditis as the primary manifestation of SARS-CoV-2 infection in a 20-year-old male patient with no known cardiovascular (CV) disorders or risk factors. The patient presented with pleuritic chest pain and high fever, with no respiratory symptoms. Electrocardiogram (ECG) and echocardiogram changes were consistent with pericarditis; concomitant elevation of cardiac enzymes revealed myocardial involvement. The patient had a slow but favourable evolution with no apparent impact on cardiac function. Other causes of myopericarditis were excluded and SARS-CoV-2 admitted as the most likely aetiological agent. This case highlights possible cardiac involvement in SARS-CoV-2 infection with little or no pulmonary disease in a young healthy patient. Such systemic and potentially troublesome manifestations of COVID-19 are increasingly being described. LEARNING POINTS: Acute myopericarditis is a possible manifestation of SARS-CoV-2 infection.SARS-CoV-2 cardiac involvement may occur both in older and in younger previously healthy subjects, and could be more frequent than expected.Further investigation should address the prevalence of myocardium and pericardium involvement in COVID-19 patients, as well as its complications, sequelae and prognostic value for both older and young patients.
RESUMO
BACKGROUND: Proactive therapeutic drug monitoring (pTDM) may improve treatment outcomes in inflammatory bowel disease. AIMS AND METHODS: We compared 135 patients following a prospective pTDM protocol aiming at an infliximab trough level (IFXTL) between 5 and 10 µg/ml with sequential measurements of Fc, with 108 patients from a retrospective group under conventional management. We evaluated the rates of Fc remission (<250 µg/g) and other clinical outcomes at 2-year of follow-up. RESULTS: pTDM associated with higher rates of Fc remission (69.6% vs. 50.0%; P = 0.002), and steroid-free clinical remission (78.4% vs. 55.2%, P = 0.028) with a trend for clinical remission (79.3% vs. 68.5%, P = 0.075). There was no difference in treatment discontinuation (P = 0.195), hospitalization (P = 0.156), and surgery (P = 0.110). Higher IFXTL associated with Fc remission at week 14 (6.59 vs. 2.96 µg/ml, P < 0.001), and at the end of follow-up (8.10 vs. 5.03 µg/ml, P = 0.001). In patients reaching Fc remission after week 14, IFXTL increased from week 14 to the end of follow-up (2.71 vs. 8.54 µg/ml, P < 0.001). Fc remission associated with higher rates of clinical (85.8% vs. 56.8% P < 0.001) and steroid-free clinical remission (86.9% vs. 50.0% P < 0.001), lower IFX discontinuation (8.8% vs. 36.8%, P < 0.001), and hospitalization (13.5% vs. 33.7%, P < 0.001), without significance for surgery (6.1% vs. 12.6%, P = 0.101). CONCLUSION: pTDM was more effective than conventional management in inducing Fc remission which was associated with improved outcomes.
