RESUMEN
BACKGROUND: Anti-TNF therapy represented a landmark in medical treatment of ulcerative colitis (UC). There is lack of data on the efficacy and safety of these agents in Brazilian patients. The present study aimed to analyze rates of clinical and endoscopic remission comparatively, between adalimumab (ADA) and infliximab (IFX), in Brazilian patients with UC, and evaluate factors associated with clinical and endoscopic remission after 1 year of treatment. METHODS: A national retrospective multicenter study (24 centers) was performed including patients with UC treated with anti-TNF therapy. Outcomes as clinical response and remission, endoscopic remission and secondary loss of response were measured in different time points of the follow-up. Baseline predictive factors of clinical and endoscopic remission at week 52 were evaluated using logistic regression model. Indirect comparisons among groups (ADA and IFX) were performed using Student's t, Pearson χ2 or Fisher's exact test when appropriated, and Kaplan Meier analysis. RESULTS: Overall, 393 patients were included (ADA, n = 111; IFX, n = 282). The mean age was 41.86 ± 13.60 years, 61.58% were female, most patients had extensive colitis (62.40%) and 19.39% had previous exposure to a biological agent. Overall, clinical remission rate was 66.78%, 71.62% and 82.82% at weeks 8, 26 and 52, respectively. Remission rates were higher in the IFX group at weeks 26 (75.12% vs. 62.65%, p < 0.0001) and 52 (65.24% vs. 51.35%, p < 0.0001) when compared to ADA. According to Kaplan-Meier survival curve loss of response was less frequent in the Infliximab compared to Adalimumab group (p = 0.001). Overall, endoscopic remission was observed in 50% of patients at week 26 and in 65.98% at week 52, with no difference between the groups (p = 0.114). Colectomy was performed in 23 patients (5.99%). Age, non-prior exposure to biological therapy, use of IFX and endoscopic remission at week 26 were associated with clinical remission after 52 weeks. Variables associated with endoscopic remission were non-prior exposure to biological therapy, and clinical and endoscopic remission at week 26. CONCLUSIONS: IFX was associated with higher rates of clinical remission after 1 year in comparison to ADA. Non-prior exposure to biological therapy and early response to anti-TNF treatment were associated with higher rates of clinical and endoscopic remission.

BACKGROUND: The IBD National Patient Registry is an initiative of the GEDIIB (Brazilian Study Group of Inflammatory Bowel Disease) who aims to survey the epidemiological profile of IBD patients through the creation of a centralized registry with data on patients monitored in public and private health services which will allow the planning of actions by the GEDIIB to facilitate the diagnosis and access to treatment of IBD, enabling the implementation of actions of the GEDIIB and the partnership with government agencies to improve care and, consequently, the quality of life of patients with IBD. This study aims to show the results of the IBD National Patient Registry. METHODS: A cohort study was performed. Data were collected from July 2020 to August 2021. Data were obtained from medical records and/or from patients during the regular follow-up visit and stored in pre-established records for further analysis. Only patients with an established diagnosis of CD and UC were included. The study was approved by the local ethical committees and all patients signed the consent form. RESULTS: In total, 797 patients were included, 60% with UC and 40% with CD; 52.9% from University Hospitals. The mean age was 44.75 ± 16.11 (12 - 92y), 59.9% female, 59.3% married, 76.4% Caucasian, 85.1% non-smokers, 30.5% completed higher education, 14.9% presented familial history of IBD. The age of onset of symptoms ranged from 3 - 79 years (32.94 ± 14.22) and 33.2% presented diarrhea as an initial manifestation. The age of diagnosis ranged from 4 - 81 years (35.07 ± 14.60) and the time from symptoms to diagnosis ranged from 1 to 2 years. The Montreal classification of CD patients were A1: 6.3%, A2: 59.9%, A3: 33.8%; L1: 38%, L2: 16.7%, L3: 43.9%, B1: 51.5%, B2: 27.8%, B3: 7.8%; perianal 12.8%. In UC, 47.8% presented pancolitis, 30.3% left-sided and 21.8% distal colitis. EIMs were present in 45.7% of patients, the most frequent being rheumatological 21.8%. Comorbidities were present in 72%, the most frequent were high blood pressure (15.3%) and diabetes (6.3%); 50% were with BMI > 25 Kg/m2. Most of the patients were in use of medical therapy (95.5%), of which 81.3% salicylate, 70.3% biological therapy, 49% immunosuppressor, 25.6% corticosteroid and 1.2% tofacitinib. Regarding biological therapy, the following medications were used: infliximab 47.6%, adalimumab 28.4%, vedolizumab 9.5%, ustekinumab 7.5%, certolizumab 2.2% and golimumab 1.3%. Eleven women used the medication during pregnancy. IBD surgery-related was performed in 69.7%, 77.2% abdominal and 22.8% perianal. Almost 30% performed more than one surgery. In 62% of patients, at least one complication was reported; most of them were infective disorders, demanding prolonged hospitalizations. CONCLUSION: To date, there is no IBD epidemiologic study covering the entire Brazilian territory. The results found with the registry will be fundamental to show the epidemiology of a country with continental dimensions such as Brazil. The greater the number of researchers included and from different regions of the country, the greater the representativeness of the data and may even help direct government actions on behalf of IBD patients.
RESUMEN
Ulcerative colitis is an inflammatory bowel disease that affects the mucous membrane of the colon. The pathogenesis is not clear, but there is evidence of a complex interaction between genetic, environmental, and immunological factors. In this regard, we highlight the role of zinc in the immune system and probable control of the disease. This study evaluated the effect of zinc supplementation on the inflammatory response in patients with ulcerative colitis. A blind interventional study involving 41 patients of both sexes, who underwent either zinc gluconate supplementation (n = 23), or treatment with a placebo (corn starch) (n = 18). Patients were evaluated for dietary zinc intake, plasma and erythrocyte zinc concentrations, and serum levels of Th1/Th2/Th17 type cytokines at baseline (T0) and 30 (T1) and 60 (T2) days after intervention. Patients in the zinc supplementation group had a lower probability of having an adequate zinc intake than placebo. In this same group, there was a significant difference between plasma zinc concentrations (T1 in relation to T0, T2 in relation to T1, and T2 in relation to T0) and erythrocyte zinc (T1 in relation to T0 and T2 in relation to T1). Zinc supplementation resulted in significant changes in the concentrations of IL-2 and IL-10 without differences in the other interleukins. Zinc gluconate intervention in patients with ulcerative colitis improves the nutritional status of this mineral in these patients and positively influences their clinical outcome, reinforcing the role of zinc as an important dietary component in disease control.

The chemical investigation of the fresh flowers of Albizia lebbeck (L.) Benth. (Fabaceae, Mimosoideae) led to the isolation of two new echinocystic acid saponins. They were isolated by using chromatographic methods and their structures were elucidated by detailed 1H and 13C NMR spectral data including 2 D-NMR (COSY, HSQC, HMBC and APT) spectroscopic techniques, high-resolution electrospray ionization mass spectrometry (HRESIMS) and acid hydrolysis. Their structures were established as 16-hydroxy-3-[[O-ß-D-xylopyranosyl-(1â2)-O-α-L-arabinopyranosyl-(1â6)-2-(acetylamino)-2-deoxy-ß-D-glucopyranosyl]oxy]-(3ß,16α)-olean-12-en-28-oic acid O-6-deoxy-α-L-mannopyranosyl-(1â4)-O-6-deoxy-α-L-mannopyranosyl-(1â2)-ß-D-glucopyranosyl ester (1) and 16-hydroxy-3-[[O-ß-D-xylopyranosyl-(1â2)-O-α-L-arabinopyranosyl-(1â6)-2-(acetylamino)-2-deoxy-ß-D-glucopyranosyl]oxy]-(3ß,16α)-olean-12-en-28-oic acid 6-O-[(2S,3R,4R)-tetrahydro-3-hydroxy-4-(hydroxymethyl)-2-furanyl]-ß-D-glucopyranosyl ester (2). Additionally, the permeability property and the capacity of interaction with biological membranes of compounds 1 and 2 were investigated.

This study aimed to analyze the application of the lean philosophy in the Health Care Network (RAS) for the early diagnosis of breast cancer. This case study was produced with data from interviews, document analysis, and observation and was conducted from June to July 2019. The setting was the seat of the municipality of the North Metropolitan Region, Ceará State, Brazil, involving three points of the RAS (Primary Care Unit, Medical Specialties Center, and Polyclinic). The following issues were identified: long waiting times, first-come-first-served care, and insufficient medical workload. Implementing the theoretical model of lean philosophy would reduce the total process time from 36 days to 15 in the Primary Care Unit/Medical Specialty Center flow and from 33 to 13 days in the Primary Care Unit/Polyclinic. The presented model is an efficient reference for improving the management and early diagnosis of breast cancer in the RAS.
Objetivou-se analisar a aplicação da filosofia lean na Rede de Atenção à Saúde (RAS) para o diagnóstico precoce do câncer de mama. Trata-se de estudo de caso, com produção dos dados por entrevistas, análise documental e observação, desenvolvido entre junho e julho de 2019. O cenário foi o município sede da Região Metropolitana Norte, CE, Brasil, envolvendo três pontos da RAS (Unidade Básica de Saúde, Centro de Especialidades Médicas e Policlínica). Identificaram-se como problemas: elevado tempo de espera, atendimento por ordem de chegada e insuficiência da carga horária médica. A implementação do modelo teórico da filosofia lean reduziria o tempo total dos processos de 36 dias para 15 no fluxo Unidade Básica de Saúde/Centro de Especialidades Médicas e de 33 para 13 dias na Unidade Básica de Saúde/Policlínica. Verificou-se que o modelo apresentado se configura como referencial eficiente para melhoria da gestão e do diagnóstico precoce do câncer de mama na RAS.

BACKGROUND: Melioidosis is a serious disease caused by the bacterium Burkholderia pseudomallei which affects humans and animals. It results in a wide spectrum of clinical manifestations, mainly in the respiratory tract, progressing to septic shock and death. CASE PRESENTATION: Herein, we present a series of seven patients (median age: 41 years) with confirmed melioidosis, treated at a public hospital in Piauí State, Brazil between 2019 and 2021. The most common clinical presentations were fever, cough, pneumonia, and abdominal pain. The mean duration of antibacterial therapy with 1 g of meropenem was 28.6 ± 1.1 days. Six patients recovered and one died. The mean hospitalization time was 51.0 ± 39.2 days. CONCLUSIONS: Melioidosis is an emerging infectious disease in Brazil. Health professionals in endemic areas need to be aware of the clinical presentation and appropriate clinical management of the disease because early diagnosis and early initiation of antibiotic therapy can be life-saving.

BACKGROUND & AIMS: Changes in dietary habits including increased intake of refined sugars and fats and decreased intake of fiber have been suggested as potential risk factors for the development of inflammatory bowel diseases (IBD). Bioelectrical impedance analysis-derived phase angle (PhA) has been gaining attention in the clinical evaluation of nutritional status. In this study, we for the first time investigated the relationship of PhA and ultra-processed food intake with oxidative stress, body composition and biochemical parameters in adult patients with IBD. METHODS: Body composition and PhA were evaluated through electrical bioimpedance. Nitrite (Nox), myeloperoxidase (MPO), glutathione (GSH), malondialdehyde (MDA) and superoxide dismutase (SOD) levels were determined in both groups. Food consumption was obtained by a food frequency questionnaire (FFQ). RESULTS: In comparison with the control group, the IBD group had increased (p < 0.05) concentrations of Nox (19.95 ± 1.4 vs. 35.43 ± 7.7 µM), MDA (0.70 ± 0.31 vs. 4.56 ± 0.62 nmol/L), and GSH (9.35 ± 0.38 vs. 10.74 ± 0.51 mg NPSH/µL plasma). PhA was positively correlated with GSH (R2:0.22; p:0.02) and SOD (R2:0.25; p:0.01). IBD patients ingested higher amounts of ultra-processed foods (IBD:17.04 ± 2.76 vs. Control:24.88 ± 2.30%). However, IBD patients had better consumption of unprocessed or minimally processed foods (IBD:79.06 ± 3.07 vs. Control:67.83 ± 2.32%). We found a positive correlation between ultra-processed food consumption and MDA (R2 0.43; p:0.01). CONCLUSIONS: PhA may be a practical and effective measure in clinical follow-up of IBD patients, being associated with bilirubin levels and antioxidant enzymes. Also, we recommend evaluating consumption of ultra-processed foods, since this was related with increasing oxidative stress markers in clinical follow-up of IBD patients.

Background: In real-world experience, the number of patients using vedolizumab as first-line biological therapy was low. We aimed to evaluate the effectiveness and safety of vedolizumab in mild-to-moderate Crohn's disease (CD) biologic-naïve patients. Methods: We performed a retrospective multicentric cohort study with patients who had clinical activity scores (Harvey-Bradshaw Index [HBI]) measured at baseline and weeks 12, 26, 52, as well as at the last follow-up. Clinical response was defined as a reduction ≥3 in HBI, whereas clinical remission as HBI ≤4. Mucosal healing was defined as the complete absence of ulcers in control colonoscopies. Kaplan-Meier survival analysis was used to assess the persistence with vedolizumab. Results: From a total of 66 patients, 53% (35/66) reached clinical remission at week 12. This percentage increased to 69.7% (46/66) at week 26, and 78.8% (52/66) at week 52. Mucosal healing was achieved in 62.3% (33/53) of patients. Vedolizumab was well tolerated, and most adverse events were minor. During vedolizumab treatment, 3/66 patients underwent surgery. Conclusions: This study demonstrates the effectiveness and safety of vedolizumab as a first-line biological agent in patients with mild-to-moderate CD.
RESUMEN
BACKGROUND: Inflammatory bowel diseases are immune-mediated disorders that include Crohn's disease (CD) and ulcerative colitis (UC). UC is a progressive disease that affects the colorectal mucosa causing debilitating symptoms leading to high morbidity and work disability. As a consequence of chronic colonic inflammation, UC is also associated with an increased risk of colorectal cancer. OBJECTIVE: This consensus aims to provide guidance on the most effective medical management of adult patients with UC. METHODS: A consensus statement was developed by stakeholders representing Brazilian gastroenterologists and colorectal surgeons (Brazilian Organization for Crohn's Disease and Colitis [GEDIIB]). A systematic review including the most recent evidence was conducted to support the recommendations and statements. All recommendations/statements were endorsed using a modified Delphi Panel by the stakeholders/experts in inflammatory bowel disease with at least 80% or greater consensus. RESULTS AND CONCLUSION: The medical recommendations (pharmacological and non-pharmacological) were mapped according to the stage of treatment and severity of the disease onto three domains: management and treatment (drug and surgical interventions), criteria for evaluating the effectiveness of medical treatment, and follow-up/patient monitoring after initial treatment. The consensus targeted general practitioners, gastroenterologists and surgeons who manage patients with UC, and supports decision-making processes by health insurance companies, regulatory agencies, health institutional leaders, and administrators.

BACKGROUND: Inflammatory bowel disease (IBD) is an immune-mediated disorder that includes Crohn's disease (CD) and ulcerative colitis. CD is characterized by a transmural intestinal involvement from the mouth to the anus with recurrent and remitting symptoms that can lead to progressive bowel damage and disability over time. OBJECTIVE: To guide the safest and effective medical treatments of adults with CD. METHODS: This consensus was developed by stakeholders representing Brazilian gastroenterologists and colorectal surgeons (Brazilian Organization for Crohn's disease and Colitis (GEDIIB)). A systematic review of the most recent evidence was conducted to support the recommendations/statements. All included recommendations and statements were endorsed in a modified Delphi panel by the stakeholders and experts in IBD with an agreement of at least 80% or greater consensus rate. RESULTS AND CONCLUSION: The medical recommendations (pharmacological and non-pharmacological interventions) were mapped according to the stage of treatment and severity of the disease in three domains: management and treatment (drug and surgical interventions), criteria for evaluating the effectiveness of medical treatment, and follow-up/patient monitoring after initial treatment. The consensus is targeted towards general practitioners, gastroenterologists, and surgeons interested in treating and managing adults with CD and supports the decision-making of health insurance companies, regulatory agencies, and health institutional leaders or administrators.

Facial injections with hyaluronic acid (HA) dermal fillers have become increasingly common. Hyaluronic acid is currently the most frequently used dermal filler. When compared to collagen for the treatment of nasolabial folds, HA not only produces similar cosmetic results with smaller doses but also lasts longer. Our objective was to evaluate the results of 10 patients with vascular complications associated with HA fillers treated with ultrasound-guided injection of hyaluronidase (HYAL) according to the Brazilian Society of Dermatology guidelines. Admission clinical evaluation revealed that the most frequent signs were: livedo reticularis (100% of the patients), hypoesthesia (50%) and local pain (20%). Although 80% of the patients complained of local pain during HYAL injection, none of them persisted with pain after the procedure ended. The total dose of injected HYAL per patient ranged from 300 to 750 IU (mean 500 IU). Post-HYAL treatment Doppler ultrasound showed pervious facial arteries and veins in 100% of the patients.
RESUMEN
Crohn's disease (CD) is a relapse-remitting inflammatory bowel disease that can affect any part of the digestive system. This heterogeneous disease has multiple factors that contribute to an abnormal immune response to intestinal microorganisms. Treatment is based on the use of anti-inflammatories, corticosteroids, immunosuppressants and biologic biologic agents either alone or in combination. Surgical treatment is usual and, ten years after diagnosis, more than 80% of patients report having undergone surgical procedures related to the disease. Unfortunately, none of the treatments described offer a cure, and many cases become refractory or without therapeutic options. In this scenario, hematopoietic stem cell transplantation has been suggested because clinical remission was obtained in patients who had CD associated with malignant hematological diseases and an alternative since the first reports in 2010. In this report, the Transplantation Committee of the Brazilian Group for the Study of Inflammatory Bowel Diseases reviews the history and results of the procedure in patients with CD, detailing and discussing the various relevant points that permeate hematopoietic stem cell transplantation and cell therapy in this disease.

Phaeohyphomycosis is a distinct mycotic infection of the skin or internal organs caused by darkly pigmented (dematiaceous) fungi, which are widely distributed in the environment. Phaeohyphomycosis is most frequently an opportunistic infection in immunosuppressed patients (HIV, corticotherapy, transplant patients) or is frequently associated with chronic diseases and diabetes. The spectrum of the disease is broad and includes superficial infections, onychomycosis, subcutaneous infections, keratitis, allergic disease, pneumonia, brain abscesses and disseminated disease. Rarely, immunocompetent patients may be affected. We describe two new cases of subcutaneous phaeohyphomycosis in immunocompetent patients: in the first patient, the causative agent was Exophiala jeanselmei, a common cause of phaeohyphomycosis; and in the second, Cladophialophora carrionii, which could be identified by culture. Cladophialophora carrionii is mainly the aetiological agent of chromoblastomycosis and only rarely the cause of phaeohyphomycosis. The first patient was treated with surgical excision and oral itraconazole, and the second patient responded to oral itraconazole only. Lesions improved in both patients and no recurrence was observed at follow-up visits.

OBJECTIVES: In this review, we systematically assess whether dietary interventions are effective in attenuating inflammatory biomarkers in IBDs based on clinical trials available in the literature. RESEARCH METHODS & PROCEDURES: This review was conducted in accordance with the guidelines of the PRISMA. We used the PubMed and SciVerse Scopus databases and the Cochrane collaboration tool to assess the risk of bias in clinical trials. The PICO (patient, intervention, comparison, and outcomes) strategy was used, with the descriptors: "Inflammatory bowel disease", "Crohn's disease", "cd", "ibd", "ulcerative colitis", "uc", "Diet", "Diet Habits", "Feeding", "Nutrients", "Food Intake", "Dietary patterns", "Inflammations", "Inflammation", "acute-phase proteins", "C-reactive protein", "interleukins", "tumor necrosis factor-alpha" and "inflammatory response". There is no conflict of interest. DATA ANALYSIS: Fifteen studies were included, with a total of 627 participants. Of the total studies included, seven showed a reduction in some inflammatory markers in response to dietary interventions. This review was registered with the PROSPERO platform under number: CRD42021235150. CONCLUSIONS: The results presented in this review reveal that dietary intervention with specific characteristics may be important during the treatment of the inflammatory process in patients with IBDs.

CONTEXT: Glutamine supplementation has been applied clinical practice to treat inflammatory bowel disease (IBD). However, scientific evidence about this is still controversial. OBJECTIVE: In this review, we systematically evaluated the effects of glutamine supplementation on IBD, based on evidence from randomized clinical trials. DATA SOURCE: This review was conducted in accordance with the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). We used the PubMed and SciVerse Scopus databases. The Cochrane collaboration tool was used to assess the risk of bias in clinical trials. DATA EXTRACTION: The review was carried out by two independent researchers according to the established inclusion criteria. The PICO (patient, intervention, comparison, and outcomes) strategy was used, with the descriptors: "glutamine," "supplementation," "inflammatory bowel diseases," "Crohn's disease," and "ulcerative colitis". DATA SYNTHESIS: Seven research articles were selected for this systematic review. In these studies, glutamine was administered to the participants through oral (21-30g or 0.5g per kg of participant's body weight), enteral (7.87g-8.3 g/100g of the enteral formula), and/or parenteral (0.3 g/kg of the participant's body weight) routes. No changes in anthropometry or biochemical parameters were observed. However, in one study reduced intestinal permeability and morphometry were reported. In two other studies, a slight effect of glutamine on inflammation and oxidative stress was observed. Additionally, two other studies reported an effect of glutamine supplementation on disease activity. CONCLUSIONS: The findings obtained through this systematic review indicate that glutamine supplementation has no effect on disease course, anthropometric measurements, intestinal permeability and morphology, disease activity, intestinal symptoms, biochemical parameters, oxidative stress and inflammation markers in patients with IBD, regardless of the route of administration, either treated at a hospital or as outpatients.

BACKGROUND: Crohn's disease (CD) and ulcerative colitis (UC) are inflammatory bowel diseases (IBDs) with a remission-relapsing presentation and symptomatic exacerbations that have detrimental impacts on patient quality of life and are associated with a high cost burden, especially in patients with moderate-to-severe disease. The Real-world Data of Moderate-to-Severe Inflammatory Bowel Disease in Brazil (RISE BR) study was a noninterventional study designed to evaluate disease control, treatment patterns, disease burden and health-related quality of life in patients with moderate-to-severe active IBD. We report findings from the prospective follow-up phase of the RISE BR study in patients with active UC or CD. AIM: To describe the 12-mo disease evolution and treatment patterns among patients with active moderate-to-severe IBD in Brazil. METHODS: This was a prospective, noninterventional study of adult patients with active Crohn's disease (CD: Harvey-Bradshaw Index ≥ 8, CD Activity Index ≥ 220), inadequate CD control (i.e., calprotectin > 200 µg/g or colonoscopy previous results), or active ulcerative colitis (UC: Partial Mayo score ≥ 5). Enrollment occurred in 14 centers from October 2016 to February 2017. The proportion of active IBD patients after 9-12 mo of follow-up, Kaplan-Meier estimates of the time to mild or no activity and a summary of treatment initiation, discontinuation and dose changes were examined. RESULTS: The study included 118 CD and 36 UC patients, with mean ± SD ages of 43.3 ± 12.6 and 44.9 ± 16.5 years, respectively. The most frequent drug classes at index were biologics for CD (62.7%) and 5-aminosalicylate derivates for UC patients (91.7%). During follow-up, 65.3% of CD and 86.1% of UC patients initiated a new treatment at least once. Discontinuations/dose changes occurred in 68.1% of CD patients [median 2.0 (IQR: 2-5)] and 94.3% of UC patients [median 4.0 (IQR: 3-7)]. On average, CD and UC patients had 4.4 ± 2.6 and 5.0 ± 3.3 outpatient visits, respectively. The median time to first mild or no activity was 319 (IQR: 239-358) d for CD and 320 (IQR: 288-358) d for UC patients. At 9-12 mo, 22.0% of CD and 20.0% of UC patients had active disease. CONCLUSION: Although a marked proportion of active IBD patients achieved disease control within one year, the considerable time to achieve this outcome represents an unmet medical need of the current standard of care in a Brazilian real-world setting.

BACKGROUND: Understanding the treatment landscape of inflammatory bowel diseases (IBD) is essential for improving disease management and patient outcomes. Brazil is the largest Latin American country, and it presents socioeconomic and health care differences across its geographical regions. This country has the highest increase in IBD incidence and prevalence in Latin America, but information about the clinical and treatment characteristics of IBD is scarce. AIM: To describe the sociodemographic, clinical, and treatment characteristics of IBD outpatients in Brazil overall and in the Southeast, South and Northeast/Midwest regions. METHODS: Multicenter, cross-sectional study with a 3-year retrospective chart review component. Patients with moderate-to-severe Crohn's disease (CD) or ulcerative colitis (UC) were consecutively enrolled between October 2016 and February 2017. Active CD at enrollment was defined as a Harvey Bradshaw Index ≥ 8 or a CD Activity Index ≥ 220 or a calprotectin level > 200 µg/g or an active result based on colonoscopy suggestive of inadequate control during the previous year; active UC was defined as a partial Mayo score ≥ 5. Descriptive statistics were used to analyze all variables. RESULTS: In a total of 407 included patients, CD was more frequent than UC, both overall (264 CD/143 UC patients) and by region (CD:UC ratios of 2.1 in the Southeast, 1.6 in the South and 1.2 in the Northeast/Midwest). The majority of patients were female (54.2% of CD; 56.6% of UC), and the mean ages were 45.9 ± 13.8 years (CD) and 42.9 ± 13.0 years (UC). The median disease duration was 10.0 (range: 0.5-45) years for both IBD types. At enrollment, 44.7% [95% confidence interval (CI): 38.7-50.7] of CD patients and 25.2% (95%CI: 18.1-32.3) of UC patients presented with active disease. More than 95% of IBD patients were receiving treatment at enrollment; CD patients were commonly treated with biologics (71.6%) and immunosuppressors (67.4%), and UC patients were commonly treated with mesalazine [5-Aminosalicylic acid (5-ASA)] derivates (69.9%) and immunosuppressors (44.1%). More than 50% of the CD patients had ileocolonic disease, and 41.7% presented with stricturing disease. One-quarter of CD patients had undergone CD-related surgery in the past 3 years, and this proportion was lower in the Northeast/Midwest region (2.9%). CONCLUSION: In Brazil, there are regional variations in IBD management. CD outweighs UC in both frequency and disease activity. However, one-quarter of UC patients have active disease, and most are receiving 5-ASA treatment.
