Small-bowel (SB) cleansing is crucial to assess the reliability of capsule endoscopy (CE) findings. However, the presence of multiple grading systems is hampering their use clinical practice. In 2020, Colon CLeansing Assessment and Report (CC-CLEAR) was created and validated. We sought to develop and validate a new score for evaluation of the SB cleansing, adapted from CC-CLEAR, aiming to standardize CE reporting regarding the quality of preparation.The new grading score, SB CLeansing Assessment and Report (SB-CLEAR), divided the SB into 3 tertiles, each being scored depending on the percentage of visualized mucosa (0-50%; 1-50-75%; 2-75%; 3-90%). Overall classification was a sum of each segment score, graded between excellent (8-9), good (6-7), and inadequate (0-5). Any segment scoring ≤1 resulted in inadequate overall classification. CE videos were prospectively evaluated by 2 experienced CE readers blinded to each other.We included 52 CEs, 41(78.8%) female, with a mean age of 57.9±17.9 years. Inter-observer agreement was very strong for each tertile (first - r=0.863; second - r=0.865; third - r=0.861; p0.001), which resulted in overall excellent correlation when considering the quality of preparation in all tertiles (r=0.940; p0.001). By applying final classifications of "inadequate", "good" and "excellent", correlation between observers was also very strong (r=0.875; p0.001).SB-CLEAR is an innovative and reproductible grading score for evaluation of SB preparation quality in CE, with overall excellent inter-observer agreement. Along with CC-CLEAR, this may become a valuable tool to uniformize reporting of bowel preparation quality in CE.

Background Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection may lead to the development of the novel coronavirus disease (coronavirus disease 2019 [COVID-19]). Scarce data are available regarding safety and efficacy of SARS-CoV-2 vaccination in inflammatory bowel disease (IBD) patients, which may present differences between subgroups. Lower humoral immunological response could require additional booster injections. Methods This is a prospective study including adult patients with IBD after complete vaccination against SARS-CoV-2 infection with BioNTech vaccine. Patients with previous SARS-CoV-2 infection were excluded. A control group with healthy individuals matched for age and sex was also analyzed. Blood samples were collected 30 days after complete vaccination to quantify immunoglobulin G (IgG) antibody titers against SARS-CoV-2 in both groups. Results The final sample included 81 IBD and 32 non-IBD patients, 55 (48.7%) of them women, with a mean age of 40.2 ± 13.0 years. From IBD patients, 58 (71.6%) had Crohn’s disease and 23 (28.4%) had ulcerative colitis. IBD patients had significantly lower median anti-SARS-CoV-2 IgG levels when compared with the control group (6479 [interquartile range (IQR) 1830-11883, 10 053] AU/mL vs 13 061 [IQR 2826-21427, 15 539] AU/mL; P = .003). Regarding IBD medication, significant lower levels of SARS-CoV-2 IgG antibodies when compared with control subjects were observed in patients treated with thiopurines (5423 [IQR 3109-13369, 10 260] AU/mL; P = .011), methotrexate (834 [IQR 507-3467, 4155] AU/mL; P = .002), anti-tumor necrosis factor α agents (5065 [IQR 1033-11669, 10 636] AU/mL; P = .001), and corticosteroids (548 AU/mL; P = .001). The incidence of SARS-CoV-2 infection after vaccination was also significantly higher in patients treated with these agents. Conclusions IBD patients treated with immunomodulators, anti-tumor necrosis factor α agents and corticosteroids presented significantly lower anti-SARS-CoV-2 IgG levels following complete vaccination when compared with healthy control subjects. These findings support the benefit of additional booster injections in this population.

Este artículo forma parte del monográfico Turismo, peregrinación y comunidades, coordinado por Carlos Pazos-Justo, Beatriz Busto y Susana Sotelo [Resumo] Este texto tem como ponto de partida a análise de documentos jurídicos que estiveram na base da aprovação pelo Governo de Portugal do Decreto-Lei nº 51/2019, de 17 de abril, - e do próprio- cujo âmbito é definir o “itinerário do Caminho de Santiago”, tendo por objeto a “salvaguardar, valorização e promoção do Caminho de Santiago” em território português. Trata-se do primeiro diploma legal cujo corpo normativo visa regular o procedimento de “certificação” com vista ao reconhecimento do interesse público dos itinerários e a consequente utilização da Marca “Caminho de Santiago Certificado”. Nesta análise procura-se aferir de que modo a “repartição de responsabilidades com os cidadãos e com outros órgãos da administração pública de forma que, em matéria de património cultural, passe a evidenciar-se uma visão integrada e participada (...)” -preconizado no Programa do XXII Governo Constitucional- e se a mesma se encontra espelhado naquele diploma legal. Por fim, pretende-se extrair algumas reflexões no domínio da instrumentalização do Direito na determinação das “alianças” e quais as possíveis “ameaças” dessa instrumentalização. [Abstract] The study is based on an analysis of the legal documents behind Decree-Law nº 51/2019 (17 April), and the text of the legislation itself, whose purpose is to define the Portuguese Way of St James route in order to ‘safeguard, enhance and promote’ the pilgrimage in Portugal. This is the first piece of legislation designed to regulate the Way of St James certification procedure, prompted by public interest in the route and increased use of the ‘Caminho de Santiago Certified’ brand. The analysis assesses how the sharing of responsibilities with citizens and other public administration bodies to ensure an integrated, participatory view of heritage (as recommended in the Portuguese Programme for Government, 2019-2023) is reflected in Decree-Law 51/2019. The article concludes with a series of reflections on the instrumentalisation of law in the creation of these ‘alliances’ and the possible dangers of such a strategy.

Azathioprine (AZA)-induced pancreatitis (AIP) is a common, idiosyncratic adverse effect whose incidence and risk factors data in inflammatory bowel disease (IBD) patients are not fully clarified. We aimed to establish the incidence, clinical course and identify risk factors for AIP.A retrospective study including all IBD patients on AZA between January 2013 and July 2020 was conducted. Patients with AIP were considered.Azathioprine-induced pancreatitis occurred in 33 patients (7.5%; 442 patients on AZA). The mean time receiving AZA until AIP was 25 days, with a mean dose of 88 mg. All patients had a mild course of disease, which resolved with suspension of AZA and with no complications. Smoking (P = 0.02), single daily dose of AZA (P0.001), and concomitant budesonide (P = 0.001) were risk factors for AIP. In multivariate analysis, concomitant treatment with budesonide (odds ratio, 5.3; P = 0.002) and single daily dose of AZA (odds ratio, 3.8; P = 0.002) were the only predictors of AIP.Although AIP was a relatively common adverse effect, it presented a mild course in all patients. Smoking, concomitant use of budesonide, and single-dose regimen of AZA should be avoided in IBD patients treated with AZA.

BACKGROUND AND AIM The RHEMITT score (Renal disease; Heart failure; Endoscopic findings; Major bleeding; Incomplete SBCE; Tobacco; Treatment by enteroscopy) was the first score to accurately predict the individual risk of small bowel rebleeding after capsule endoscopy (SBCE). The aim of the study is on the prospective validation of the RHEMITT score. METHODS Cohort of consecutive patients with mid-gastrointestinal bleeding (MGIB) submitted to SBCE and followed prospectively, during at least 12 months, since 2017 until 2020. Rebleeding was defined as an overt bleeding event (melena or hematochezia) or a hemoglobin decrease of at least 2 g/dL. The RHEMITT score was calculated for each patient and the rebleeding rates compared. The performance of the score was tested by calculating the area under curve of the receiver operator characteristic curve. A rebleeding-free survival was assessed, corresponding to the period between the date of SBCE and the date of the first post-SBCE rebleeding event. RESULTS We included 162 patients, 102 (62.9%) were female, with a mean age of 64 years old. The sensitivities and specificities of the score grades for predicting rebleeding were as following: for low-risk patients, 0% (0-10%) and 28.8% (21.1-36.5%); for intermediate-risk patients, 23.3% (8.2-38.4%) and 72% (64.3-79.7%); for high-risk patients, 76.7% (61.6-91.8%) and 99.2% (97.7-100%), corresponding to an area under curve of the receiver operator characteristic of 0.988 (P

Physical activity has been proposed as a potential factor influencing capsule endoscopy (CE) gastric transit time (GTT). However, there is no reported factual evidence confirming this association. We aimed to prospectively assess the effect of physical activity in the first hour of CE in the occurrence of prolonged GTT.This is a prospective study including consecutive patients undergoing CE. For each patient, a step counter was attached to the CE register. The number of steps during the first hour of the procedure was registered. The main outcome was prolonged GTT (CE remaining in the stomach for 1 h). Outcomes were adjusted for possible confounders by multivariate analysis.We included 100 patients, 60% undergoing small bowel CE and 40% colon CE. The mean number of steps in the first hour was significantly lower in patients with prolonged GTT (2009 ± 1578 steps) comparatively with those without prolonged GTT (3597 ± 1889 steps) (P 0.001). On multivariate analysis including significant confounders, steps in the first hour were an independent predictor of prolonged GTT (P = 0.018). Single-handedly, the number of steps taken in the first hour had a good acuity for predicting prolonged GTT (area under the curve = 0.74; P 0.001), with an optimal cut-off of 2000 steps (sensitivity 81.3% and specificity 70%).Physical activity during the first hour of CE significantly decreased the occurrence of prolonged GTT. These findings pave the way for further definition of clear instructions to give to patients undergoing CE.

Current colon capsule (CC) cleansing grading scales rely on subjective parameters and lack proper interobserver agreement. We should strive for higher intra- and interobserver agreement for the evaluation of the cleansing quality of CCs. Here we sought to validate a new grading scale for the evaluation of CC cleansing.For the new grading scale, named Colon Capsule CLEansing Assessment and Report (CC-CLEAR), the colon was divided in 3 segments: right-sided, transverse, and left-sided colon. Each segment was scored according to an estimation of the percentage of visualized mucosa (0, 50%; 1, 50%-75%; 2,75%; 3,90%). The overall cleansing classification was a sum of each segment score, grading between excellent (8-9), good (6-7), and inadequate (0-5). Any segment scoring ≤1 resulted in inadequate overall classification. Videos were reviewed and scored using CC-CLEAR and the Leighton-Rex grading scale by 2 experienced operators blinded to each other. Kendall's coefficient evaluated inter- and intraobserver agreement.We included 58 consecutive CCs, corresponding to 75.9% women, with a mean age of 65 years. Overall cleansing CC-CLEAR classifications were as follows: reader A, 22.4% (n = 13) excellent, 31% (n = 18) good, and 46.5% (n = 27) inadequate; and reader B, 24.1% (n = 14) excellent, 22.4% (n = 13) good, and 53.4% (n = 31) inadequate. CC-CLEAR interobserver agreement was superior to the Leighton-Rex scale (Kendall's W .911 vs .806, respectively; P .01). The intraobserver agreement for CC-CLEAR was excellent for both readers (P.01).CC-CLEAR is a new practical and reliable grading scale for the evaluation of bowel preparation quality using a CC, with excellent inter- and intraobserver agreement.

BACKGROUND AND AIMS Terminal ileitis is a common condition and may be associated with a wide variety of diseases, mostly Crohn's disease. Although small bowel capsule endoscopy (SBCE) is a valuable diagnostic tool for small-bowel diseases, data regarding its diagnostic impact on isolated terminal ileitis are sparse. The aim of this study was to evaluate the diagnostic value of SBCE for isolated terminal ileitis detected during ileocolonoscopy and to assess predictive factors for Crohn's disease diagnosis. METHODS This is a retrospective study including consecutive patients undergoing SBCE after diagnosis of terminal ileitis without colonic mucosal abnormalities on ileocolonoscopy between January 2016 and September 2019. RESULTS This included 102 patients with isolated terminal ileitis on ileocolonoscopy. Positive findings on SBCE were found in 82.4% of patients. After performing SBCE, 61.8% of patients had a final diagnosis, being Crohn's disease the most common (34.3%), followed by NSAIDs enteropathy (12.7%). Extraintestinal manifestations (P = 0.003), weight loss (P = 0.02), abnormal imaging (P = 0.04) and positive SBCE findings (P = 0.001) were independently associated with Crohn's disease diagnosis. Regarding SBCE, presence of proximal small-bowel disease (P = 0.02), diffuse findings (P = 0.002) and moderate to severe inflammatory activity (Lewis score ≥ 790) (P < 0.001) were independently associated with Crohn's disease diagnosis. CONCLUSION SBCE is a valuable tool that should be systematically used in patients with isolated terminal ileitis on ileocolonoscopy, since it revealed a high diagnostic yield, supporting a definite diagnosis in almost two-thirds of patients, and Crohn's disease diagnosis in approximately one-third of patients. A diagnosis of Crohn's disease should be considered when a patient with terminal ileitis on ileocolonoscopy shows proximal involvement, diffuse findings and/or moderate to severe inflammatory activity on SBCE.

Small bowel capsule endoscopy (SBCE) is the gold standard for suspected small bowel bleeding (SBB). Angioectasias are the most common vascular anomalies in the gastrointestinal tract and have been reported as the source of SBB in up to 80% of patients. Considering their frequency, their usual intermittent bleeding nature, and their risk of rebleeding, the aim of this study was to identify some features and possible predictors of rebleeding in the presence of these lesions. This is a retrospective study, which included consecutive SBCE with angioectasias between April 2008 and December 2017 with a minimum follow-up of 12 months. Rebleeding was defined as a drop of hemoglobin ≥ 2 g/dl and/or in the presence of hematochezia or melenas with negative esophagogastroduodenoscopy and ileocolonoscopy. Data were collected from medical records, and angioectasias were classified by number, location, size, and type. Univariate and multivariable statistical analysis was performed to identify possible predictors of rebleeding. From a total of 630 patients submitted to SBCE for suspected SBB, 129 with angioectasias were included; 59.7% were female, with a median age of 72 (19–91) years old and a mean follow-up of 44.0 ± 31.9 months. In 32.6% (n = 42) of the patients, at least one episode of rebleeding was documented. The presence of heart failure (OR 3.41; IC95% 1.18–9.89; p = 0.024), the size of the angioectasias (OR 5.41; IC95% 2.15–13.6; p

Small bowel capsule endoscopy (SBCE) is the reference standard tool for diagnosing small bowel bleeding (SBB). The "TOP 100", which performs an automatic selection of the 100 images that mostly likely contain abnormalities, emerged as a new functionality of the RAPID Reader® software in 2017. Background Small bowel capsule endoscopy (SBCE) is the reference standard tool for diagnosing small bowel bleeding (SBB). The “TOP 100”, which performs an automatic selection of the 100 images that mostly likely contain abnormalities, emerged as a new functionality of the RAPID Reader® software in 2017. Aim To compare the concordance of findings between the standard reading (SR) and the use of TOP 100 in suspected SBB. Methods Retrospective study, including consecutive patients submitted to SBCE for suspected SBB. Two experienced readers performed SR and reported the most important findings. Another experienced reader, who was blinded to the SR results, reviewed all the SBCE videos using TOP 100 and reported the most important findings. The relevant findings were defined as the presence of high bleeding potential lesions (P2). Results 97 patients were included. The TOP 100 detected 81/97(83.5%) of the P2 lesions, in particular 64/67(95.5%) of the angioectasias and 17/30(56.7%) of the ulcers. The TOP 100 identified all sites of active bleeding (n = 9). Conclusion The TOP 100 identified all sites of active bleeding, as well as the vast majority of significant lesions (83.5%); in particular, it detected over 95% of the angioectasias. Although SR remains the reference standard in the SBCE review, these findings demonstrate that TOP 100 allows for a quick preview reading constituting an important asset in the identification of lesions that may require priority full review and intervention planning

Direct oral anticoagulants (DOACs) became a widespread alternative in anticoagulant therapy. Nevertheless, concerns are raised about their safety, with increased gastrointestinal bleeding rates being described. There are scarce studies regarding DOACs effect on small-bowel capsule endoscopy (SBCE) findings. We aimed to assess if the detection of lesions with high bleeding potential on SBCE was significantly different in patients treated with DOACs when compared to non-anticoagulated patients and to patients anticoagulated with other agents.Cohort study including consecutive patients who underwent SBCE for suspected mid-gastrointestinal bleeding (MGIB) in 2019 and 2020.From 148 patients, 38 (25.7%) were anticoagulated, of which 26 (68.4%) with DOACs. P2 lesions were detected in 36.5% (Despite their undeniable cardiovascular benefits and easy applicability, DOACs should still be considered with caution. These drugs were significantly associated with higher risk of potentially bleeding lesions on SBCE when compared to other anticoagulants and represent an independent risk factor for MGIB when adjusted for other variables.

Every year, agri-food industries in industrialised countries produce approximately 1.3 billion tonnes of food loss and waste. The adoption of a circular economy policy has received special attention by the agri-food industries, allowing for the creation and development of new food products made of by-products that would otherwise be wasted or used for secondary applications. The present work, of an exploratory nature, aims to assess how consumers conceptualise the circular economy in order to identify consumer recognition of the use of by-products from the food industry to upcycle food products and to evaluate attitudes towards the circular economy. To this end, a mixedmethodology was applied to 340 participants. The first part was qualitative and used free word association to evaluate consumers’ conceptualisation of the circular economy and use of by-products as foods. Data were analysed by grouping the responses into exclusive and exhaustive categories and a correspondence analysis was also performed to originate perceptual maps. Additionally, a questionnaire was designed to evaluate major concepts and attitudes correlated with the circular economy. Data were reduced by principal component analysis (PCA) and participants grouped through clustering. Results showed that consumers understand circular economy as related mainly into Sustainability, Economy, and Circularity dimensions. Participants had great difficulty identifying the by-products used as foods or as food ingredients. From the quantitative data, four groups were identified based on the associations to the six principal components originated by the PCA. However, the results highlighted a very low association with all clusters of the Food Valorisation dimension within the concept of the circular economy, and also a lack of a clear understanding of consumers’ attitudes towards food products from the circular economy. Greater promotion and dissemination by the competent entities aimed at the general public may contribute towards greater integration, participation and acceptance of the circular economy concept for the upscaling of food by-products. info:eu-repo/semantics/publishedVersion

In order to optimize the rate of adequate cleansing in colon capsule, it may be important to identify risk factors that can predict a suboptimal colon preparation.To define predictive factors for inadequate bowel preparation in colon capsule, according to CC-CLEAR (Colon Capsule CLEansing Assessment and Report).Retrospective, single center, cohort study. Patients' demographics, data, and quality of bowel preparation, according to CC-CLEAR, were collected retrospectively. A univariate analysis tested the association between covariables and the outcome, inadequate cleansing. The statistically significant variables were included in multivariable logistic binary regression, and a receiver operating characteristic curve (ROC) assessment was performed.We included 167 consecutive colon capsules. Sixty-eight percent (A previous inadequate colon cleansing, the use of chronic laxative and antidepressant, or impaired mobility are predictors of inadequate colon capsule cleansing, as assessed by the CC-CLEAR. These 4 predictors come together as a model enabling an accurate categorization of the patients at major risk of inadequate bowel preparation for capsule colonoscopy, with an excellent discriminative power and performance, which seems useful for the selection of patients for tailored optimization of the colon cleansing protocol.Com o intuito de otimizar a taxa de preparações intestinais adequadas em cápsula do cólon, poderá ser importante identificar fatores de risco preditivos de preparações sub-ótimas.Definir fatores preditivos de preparação intestinal inadequada em cápsula do colon, de acordo com a CC-CLEAR (Colon Capsule CLEansing Assessment and Report).Estudo de coorte retrospetivo, no qual as variáveis demográficas, clínicas e a qualidade de preparação intestinal, de acordo com a CCCLEAR, foram colhidas retrospetivamente. Uma análise univariada testou a associação entre as covariáveis e a variável outcome – preparação intestinal inadequada. As variáveis estatisticamente significativas foram incluídas num modelo de regressão logística binária e performance testada com a realização de curva ROC.Incluímos 167 cápsulas do colon consecutivas. Sessenta e oito por cento (Uma preparação cólica prévia inadequada, o uso crónico de laxantes e antidepressivos e um défice de mobilidade são preditores de preparação intestinal inadequada em cápsula do cólon, de acordo com a CC-CLEAR. Estas 4 variáveis formam um modelo que permite a categorização, com excelente acuidade, de indivíduos com risco elevado para preparação intestinal inadequada em cápsula do colon, o que parece ser útil para uma otimização caso a caso do protocolo de preparação intestinal.

BACKGROUND small-bowel capsule endoscopy (SBCE) is the gold standard for the study of small-bowel bleeding (SBB). Recent studies suggest that longer small-bowel transit times (SBTT) may be associated with a higher diagnostic yield of SBCE. AIM the aim of the study was to investigate if longer SBTT is a predictive factor of positive findings on SBCE in a population that underwent SBCE for suspected SBB. METHODS a retrospective single-center study including consecutive SBCEs between May 2012 and May 2019, due to suspected SBB. A positive SBCE was considered in the presence of lesions with high bleeding potential such as ulcers, angioectasias, and tumors (P2 lesions, according to the Saurin classification). RESULTS we included 372 patients, 65.9 % female, with a median age of 67 (IQR: 19-97) years. We observed that patients with P2 lesions (n = 131; 35.2 %) in SBCE exhibited a longer SBTT (p = 0.01), were older (p < 0.001), were more frequently male (p = 0.019), and suffered more frequently from arterial blood hypertension (p = 0.011), diabetes (p = 0.042), chronic kidney disease (p = 0.003), and heart failure (p = 0.001). In the logistic analysis, significant predictive factors for the presence of P2 lesions included age (OR: 1.027; 95 % CI: 1.009-1.045; p = 0.004), SBTT (OR: 1.002; 95 % CI: 1.001-1.005; p = 0.029), and male gender (OR: 1.588; 95 % CI: 1.001-2.534; p = 0.049). CONCLUSIONS patients with longer SBTT had higher rates of lesions with high bleeding potential (P2). SBTT along with previously well-defined factors such as age and male gender were the only independent predictive factors for the presence of P2 lesions. These findings may suggest that a slower passage of the capsule through the small bowel may allow a better diagnostic yield for significant lesions.

Optimal strategies for using small-bowel capsule endoscopy (SBCE) in established small-bowel Crohn's disease (CD) remain uncertain. Mucosal healing (MH) has emerged as a valuable predictor of a flare-free disease. We aimed to evaluate the occurrence of disease flare on patients with small-bowel CD and MH, as well as to create a score identifying patients in higher risk for this outcome.We analyzed consecutive patients submitted to SBCE for assessment of MH and included those where MH was confirmed. The incidence of disease flare was assessed during follow-up (minimum 12 months). A score predicting disease flare was created from several analyzed variables.From 47 patients with MH, 12 (25.5%) had a flare (versus 48.3% in excluded patients without MH; p = 0.01). Age ≤ 30 years (OR = 70; p = 0.048), platelet count ≥ 280 × 10Patients with small-bowel CD and MH were not free of disease flares on the subsequent year, despite presenting lower rates when compared to those without MH. The APEX score demonstrated excellent accuracy at stratifying patients relapse risk and guiding further therapeutic options for patients achieving MH.

The use of combination therapy of anti-TNFα and thiopurines in inflammatory bowel disease (IBD) is associated with greater efficacy and lower immunogenicity. However, the dose of thiopurine in this setting remains to be elucidated.To compare the trough levels, anti-TNFα antibodies and the inflammatory biomarkers between three groups in combotherapy: group 1 (dose of azathioprine1 mg/kg); group 2 (dose of azathioprine ≥1 and2 mg/kg), and group 3 (dose of azathioprine ≥2 mg/kg).A retrospective study was performed, selecting all patients with established diagnosis of IBD who were on combined maintenance treatment.We included 99 patients, 52.5% female with median age 33 (17-61) years. Eighty patients (80.8%) were diagnosed with Crohn's disease and 19 (19.2%) with ulcerative colitis. Seventy-one (71.8%) patients were on infliximab (IFX) and 28 (28.3%) were on adalimumab (ADA). In patients treated with IFX, there were no differences in trough levels (In our cohort, there were no differences between anti-TNFα trough levels, formation of anti-TNFα antibodies or inflammatory biomarkers among patients in combotherapy with azathioprine, irrespective of its dosage. In conclusion, our study suggests that maintaining therapeutic levels of anti-TNFα drugs without antibodies formation is feasible with lower doses of azathioprine, minimizing its side effects.

Background: Perianal disease is associated with a disabling course of Crohn’s disease (CD). We aim to study the impact of perianal disease on CD remission rates, after a 1-year course of infliximab in combination therapy with azathioprine. Methods: This was a retrospective, single-center cohort study, including consecutive CD patients on combination therapy, followed for 1 year since induction. The outcome variable was split into clinical and endoscopic remissions. The correlation toward the outcome variable was assessed with univariate and multivariate analysis and a survival assessment, using SPSS software. Results: We assessed 74 CD patients, of whom 41 (55.4%) were female, with a mean age of 36 years. Thirty-nine percent of the patients presented perianal disease at diagnosis (n = 29). We documented 70.3% clinical and 47.2% endoscopic remissions. Several variables had statistical significance toward the outcomes (endoscopic and clinical remissions) in the univariate analysis. After adjusting for confoundment, patients with perianal disease presented an odds ratio (OR) of 0.201 for achieving endoscopic remission (CI: 0.054–0.75, p value 0.017) and an OR of 0.203 for achieving clinical remission (CI: 0.048–0.862, p value 0.031). Sixty-six patients (89.2%) presented an initial response to treatment, from whom, 20 (30.3%) exhibited at least 1 disease relapse (clinical and/or endoscopic). Patients with perianal disease presented higher probability of disease relapse, displaying statistically significant difference on Kaplan-Meier curves (Breslow p value 0.043). Conclusion: In the first year of combination therapy, perianal disease is associated with an 80% decrease in endoscopic and clinical remission rates and higher ratio of disease relapse.

Background: Capsule endoscopy is a widely recognized method to study the small bowel, including in patients with Crohn’s disease (CD). The Lewis score (LS) is a valuable tool in this setting, able ...
