RESUMO

Background: Inflammatory bowel diseases (IBDs) are chronic conditions that negatively interferes with the quality of life of the patients, on a physical, emotional, and social level. Its symptoms can vary including diarrhea, bleeding, abdominal pain, fever, and weight loss, depending on the type and location and severity of the disease. Despite evolving treatment, they do not always achieve control of the symptoms, so between 23% and 45% of people with idiopathic chronic ulcerative colitis, and up to 75% of those with Crohn's disease, eventually, will need surgery. Objective: The increase in its incidence in Latin America has promoted a renewed interest on the part of the medical and scientific community in standardizing and unifying criteria for the proper diagnosis and management of the disease, which is part of the current discussions of various events; however, this interest has not yet been reflected in policies and initiatives by governments to address the disease. We decided to develop a consensus meeting in order to elucidate the actual situation of IBD care in our region. Design: The methodology employed to build the consensus document derived from a review of literature, evidence, and policies on IBD, followed by a process of validation and feedback with a group of 10 experts in the field. Methods: Nine experts from different countries in Latin America were reunited in web meetings on 2 days and voted on topics derived from the consensus document. A full agreement with 100% approval was needed, so topics were discussed to reach the consensus otherwise were removed. Results: There is still a lack of information about IBD in Latin America, therefore IBD continues to be an 'invisible' disease and is little recognized by decision-makers. Conclusion: This document describes the current situation of IBDs in the Latin American region, highlighting the main barriers and challenges in timely access to diagnosis and treatment, in order to demonstrate the need to promote the development and implementation of policies, in order to improve the quality of care of patients with IBD.

RESUMO

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.

RESUMO

Background: Ulcerative colitis (UC) is a chronic inflammatory bowel disease which affects the colorectal mucosa with a relapsing-remitting pattern. The therapeutic options currently available for the medical management of UC include many options. Tofacitinib is an oral small molecule, Janus kinase (JAK) inhibitor, more selective for JAK1 and JAK3, which reduces the inflammatory process involved in the pathogenesis of UC. Methods: Retrospective observational multicentric study of patients with UC who used tofacitinib in any phase of their treatment. Clinical remission and response (according to Mayo score), mucosal healing, primary and secondary loss of response, discontinuation of the drug with possible causes, and the need for dose optimization or switching to biologicals, need for surgery and adverse events were evaluated. Results: From a total of 56 included patients, clinical remission was observed in 43.6% at week 12, 54.5% at week 26, 57.9% at week 52, and 40% at the last follow-up visit. Clinical response was observed in 71.4%, 81.8%, 89.5%, and 61.8% at the same time periods, respectively. Mucosal healing rates were 50% and 17.8% needed colectomy. Conclusions: Tofacitinib was effective in induction and maintenance of clinical response and remission rates, compatible to other international real-word studies and meta-analyses.

RESUMO

Crohn's disease (CD) is a chronic inflammatory disease with a complex interface of broad factors. There are two main treatments for Chron's disease: biological therapy and nonbiological therapy. Biological agent therapy (e.g., anti-TNF) is the most frequently prescribed treatment; however, it is not universally accessible. In fact, in Brazil, many patients are only given the option of receiving nonbiological therapy. This approach prolongs the subsequent clinical relapse; however, this procedure could be implicated in the immune response and enhance disease severity. Our purpose was to assess the effects of different treatments on CD4+ T cells in a cohort of patients with Crohn's disease compared with healthy individuals. To examine the immune status in a Brazilian cohort, we analyzed CD4+ T cells, activation status, cytokine production, and Treg cells in blood of Crohn's patients. Patients that underwent biological therapy can recover the percentage of CD4+CD73+ T cells, decrease the CD4+ T cell activation/effector functions, and maintain the peripheral percentage of regulatory T cells. These results show that anti-TNF agents can improve CD4+ T cell subsets, thereby inducing Crohn's patients to relapse and remission rates.

RESUMO

BACKGROUND: The effectiveness of ustekinumab (UST) in the treatment of Crohn's disease (CD) has been demonstrated in the pivotal Phase 3 UNITI 1 and 2 and IM-UNITI studies in both anti-TNF-naïve and anti-TNF-exposed patients. Given the selective nature of pivotal trial designs, real-world effectiveness and safety studies are warranted. We report our experience with UST treatment in a large, real-world multicenter cohort of Brazilian patients with CD. METHODS: We performed a retrospective multicenter study including patients with CD, predominantly biologically refractory CD, who received UST. The primary endpoint was the proportion of patients in clinical remission at weeks 8, 24 and 56. Possible predictors of clinical and biological response/remission and safety outcomes were also assessed. RESULTS: Overall, 245 CD (mean age 39.9 [15-87]) patients were enrolled. Most patients (86.5%) had been previously exposed to biologics. According to nonresponder imputation analysis, the proportions of patients in clinical remission at weeks 8, 24 and 56 were 41.0% (n = 98/239), 64.0% (n = 153/239) and 39.3% (n = 94/239), respectively. A biological response was achieved in 55.4% of patients at week 8, and 59.3% were in steroid-free remission at the end of follow-up. No significant differences in either clinical or biological remission were noted between bio-naïve and bio-experienced patients. Forty-eight patients (19.6%) presented 60 adverse events during the follow-up, of which 8 (13.3%) were considered serious adverse events (3.2% of 245 patients). Overall, a proximal disease location, younger age, perianal involvement, and smoking were associated with lower rates of clinical remission over time. CONCLUSIONS: UST therapy was effective and safe in the long term in this large real-life cohort of Brazilian patients with refractory CD, regardless of previous exposure to other biological agents.

RESUMO

BACKGROUND AND AIM: One of the most impacted regions by the pandemic globally, Latin America is facing socioeconomic and health-care challenges that can potentially affect disease outcomes. Recent data suggest that inflammatory bowel disease (IBD) patients do not have an increased risk of the development of COVID-19 complications. However, the impact of COVID-19 on IBD patients living in least developed areas remains to be fully elucidated. This study aims to describe the outcomes of IBD patients diagnosed with COVID-19 in countries from Latin America based on data from the SECURE-IBD registry. METHODS: Patients from Latin America enrolled in the SECURE-IBD registry were included. Descriptive analyses were used to summarize clinical and sociodemographic characteristics. The studied outcomes were (i) a composite of need for intensive care unit admission, ventilator use, and/or death (primary outcome) and (ii) a composite of any hospitalization and/or death (secondary outcome). Multivariable regression was used to identify risk factors of severe COVID-19. RESULTS: During the study period, 230 cases (Crohn's disease: n = 115, ulcerative colitis: n = 114, IBD-unclassified [IBD-U]: n = 1) were reported to the SECURE-IBD database from 13 different countries. Primary outcome was observed in 17 (7.4%) patients, and the case fatality rate was 1.7%. In the adjusted multivariable model, the use of systemic corticosteroids (odds ratio [OR] 10.97; 95% confidence interval [CI]: 3.44-34.99) was significantly associated with the primary outcome. Older age (OR 1.03; 95% CI: 1.00-1.05), systemic corticosteroids (OR 9.33; 95% CI: 3.84-22.63), and the concomitant presence of one (OR 2.14; 95% CI: 0.89-5.15) or two (OR 10.67; 95% CI: 1.74-65.72) comorbidities were associated with the outcome of hospitalization or death. CONCLUSION: Inflammatory bowel disease patients with COVID-19 in Latin America appear to have similar outcomes to the overall global data. Risk factors of severe COVID-19 are similar to prior reports.

RESUMO

The incidence and prevalence of ulcerative colitis (UC) has been reported to be rising in newly industrialised regions, such as Latin America. Here, we review data from published studies reporting demographics and clinical aspects of UC in Latin America to further understand epidemiology and disease burden. The incidence and prevalence of UC in Latin America varied between regions and studies, ranging between 0.04 to 8.00/100,000 and 0.23 to 76.1/100,000, respectively, and generally increased over the period from 1986 to 2015. The majority of patients with UC were female (53.6-72.6%) and urban residents (77.8-97.4%). Extraintestinal manifestations were reported in approximately 26-89.4% of patients. Use of biologic therapies was generally low (0.8-16.2%), with the exception of Mato Grosso do Sul, Brazil, with a greater proportion of patients tending to receive 5-aminosalicylates, immunosuppressants or corticosteroids; colectomy rates varied between studies (1.5-22%). A high proportion of patients had moderate to severe UC (45.9-73.0%) and, in 11 of 19 studies, the greatest proportion of patients had extensive disease (pancolitis). Colorectal cancer (0-1.7%) and mortality rates (0-7.6%) were low. This evaluation of published studies may influence therapeutic approaches and the development of strategies to improve healthcare access and patient outcomes, although further high-quality studies are required in patients with UC in Latin America.

RESUMO

AIM: To examine treatment decisions of gastroenterologists regarding the choice of prescribing 5-aminosalycilates (5ASA) with corticosteroids (CS) versus corticosteroids alone for patients with active ulcerative colitis (UC). METHODS: A cross-sectional questionnaire exploring physicians' attitude toward 5ASA + CS combination therapy vs CS alone was developed and validated. The questionnaire was distributed to gastroenterology experts in twelve countries in five continents. Respondents' agreement with stated treatment choices were assessed by standardized Likert scale. Background professional characteristics of respondents were analyzed for correlation with responses. RESULTS: Six hundred and sixty-four questionnaires were distributed and 349 received (52.6% response rate). Of 340 eligible respondents, 221 (65%) would continue 5ASA in a patient hospitalized for intravenous CS treatment due to a moderate-severe UC flare, while 108 (32%) would stop the 5ASA (P < 0.001), and 11 (3%) are undecided. Similarly, 62% would continue 5ASA in an out-patient starting oral CS. However, only 140/340 (41%) would proactively start 5ASA in a hospitalized patient not receiving 5ASA before admission. Most (94%) physicians consider the safety profile of 5ASA as very good. Only 52% consider them inexpensive, 35% perceive them to be expensive and 12% are undecided. On multi-variable analysis, less years of practice and perception of a plausible additive mechanistic effect of 5ASA + CS were positively associated with the decision to continue 5ASA with CS. CONCLUSION: Despite the absence of data supporting its benefit, most gastroenterologists endorse combination of 5ASA + CS for patients with active moderate-to-severe UC. Randomized controlled trials are needed to assess if 5ASA confer any benefit for these patients.

RESUMO

ABSTRACT Background Primary hypolactasia is a common condition where a reduced lactase activity in the intestinal mucosa is present. The presence of abdominal symptoms due to poor absorption of lactose, which are present in some cases, is a characteristic of lactose intolerance. , Objective Evaluate the efficacy of a product containing exogenous lactase in tablet form compared to a reference product with proven effectiveness in patients with lactose intolerance. Methods Multicentre, randomized, parallel group, single-blind, comparative non-inferiority study. One hundred twenty-nine (129) adult lactose intolerance patients with hydrogen breath test results consistent with a diagnosis of hypolactasia were randomly assigned to receive the experimental product (Perlatte(r) - Eurofarma Laboratórios S.A.) or the reference product (Lactaid(r) - McNeilNutritionals, USA) orally (one tablet, three times per day) for 42 consecutive days. Results Data from 128 patients who actually received the studied treatments were analysed (66 were treated with the experimental product and 62 with the reference product). The two groups presented with similar baseline clinical and demographic data. Mean exhaled hydrogen concentration tested at 90 minutes after the last treatment (Day 42) was significantly lower in the experimental product treated group (17±18 ppm versus 34±47 ppm) in the per protocol population. The difference between the means of the two groups was -17 ppm (95% confidence interval [95% CI]: -31.03; -3.17). The upper limit of the 95% CI did not exceed the a priori non-inferiority limit (7.5 ppm). Secondary efficacy analyses confirmed that the treatments were similar (per protocol and intention to treat population). The tolerability was excellent in both groups, and there were no reports of serious adverse events related to the study treatment. Conclusion The experimental product was non-inferior to the reference product, indicating that it was an effective replacement therapy for endogenous lactase in lactose intolerance patients.


RESUMO Contexto A hipolactasia primária é uma condição muito frequente na qual há redução da atividade da lactase na mucosa intestinal.A presença de sintomas abdominais devidos à má absorção da lactose presente em alguns casos caracteriza a intolerância à lactose. Objetivo Avaliar a eficácia de um produto contendo lactase exógena em comprimidos comparativamente a de um produto comparador com eficácia comprovada em pacientes portadores de intolerância à lactose. Métodos Estudo multicêntrico, randomizado, de grupos paralelos, com investigador cego, comparativo de não-inferioridade. Cento e vinte e nove (129) pacientes adultos portadores de intolerância à lactose e teste do hidrogênio no ar expirado compatível com o diagnóstico de hipolactasia foram randomizados para receber o produto experimental (Perlatte(r) - Eurofarma Laboratórios S.A.) ou o produto comparador (Lactaid(r) - McNeil Nutritionals, EUA), por via oral (um comprimido, três vezes ao dia), durante 42 dias consecutivos. Resultados Os dados dos 128 pacientes que efetivamente receberam o tratamento do estudo foram avaliados (66 tratados com o produto experimental e 62 com o produto comparador). Os dois grupos se mostraram homogêneos quanto aos dados demográficos e clínicos basais. A média da concentração do hidrogênio expirado aos 90 minutos no teste realizado ao final do tratamento (Dia 42) foi significativamente menor no grupo tratado com o produto experimental (17±18 ppm versus 34±47 ppm na população por protocolo). A diferença entre as médias dos dois grupos foi de -17 ppm (intervalo de confiança de 95% [IC95%]: -31,03; -3,17). O limite superior do IC95% não ultrapassou a margem de não-inferioridade estipulada a priori (7,5 ppm). As análises secundárias de eficácia confirmaram a semelhança entre os tratamentos (populações por protocolo e com intenção de tratamento). A tolerabilidade foi excelente em ambos os grupos e não houve relato de eventos adversos graves relacionados ao produto. Conclusão O produto experimental se mostrou não-inferior ao produto comparador, indicando sua eficácia no tratamento substitutivo da lactase endógena em pacientes portadores de intolerância à lactose.

RESUMO

BACKGROUND: Paradoxical cases of psoriatic lesions induced or exacerbated by anti-tumor necrosis factor (TNF)-α therapy have been reported more frequently in recent years, but data related to inflammatory bowel disease (IBD) are rare. A systematic literature review was performed to provide information about this adverse effect in patients with IBD who receive anti-TNF therapy. METHODS: Published studies were identified by a search of Medline, Embase, Cochrane, SciELO, and LILACS databases. RESULTS: A total of 47 studies (222 patients) fulfilled the inclusion criteria and were selected for analysis. Clinical and therapeutic aspects varied considerably among these reports. Of the 222 patients, 78.38% were diagnosed with Crohn's disease, and 48.20% were female. The mean patient age was 26.50 years, and 70.72% of patients had no history of psoriasis. Patients developed psoriasiform lesions (55.86%) more often than other types of psoriatic lesions, and infliximab was the anti-TNF-α therapy that caused the cutaneous reaction in most patients (69.37%). Complete remission of cutaneous lesions was observed in 63.96% of the cases. CONCLUSIONS: We found that psoriatic lesions occurred predominantly in adult patients with Crohn's disease who received infliximab and had no previous history of psoriasis. Most patients can be managed conservatively without discontinuing anti-TNF-α therapy.

RESUMO

Although therapy with tumor necrosis factor-alpha inhibitors (anti-TNF) provides beneficial effects in different immune inflammatory disorders, paradoxical cases of anti-TNF-induced psoriasis have increasingly been reported, mostly in the setting of rheumatologic diseases. To date, less than 50 cases of infliximab-induced psoriasis in inflammatory bowel disease patients have been described. The present report was aimed at describing two new cases of infliximab-induced psoriasis during therapy for Crohn's disease and at carrying out a review on this intriguing phenomenon.

RESUMO

BACKGROUND: Research has shown that fecal biomarkers are useful to assess the activity of inflammatory bowel disease (IBD). The aim of the study is: to evaluate the efficacy of the fecal lactoferrin and calprotectin as indicators of inflammatory activity. FINDINGS: A total of 78 patients presenting inflammatory bowel disease were evaluated. Blood tests, the Crohn's Disease Activity Index (CDAI), Mayo Disease Activity Index (MDAI), and Crohn's Disease Endoscopic Index of Severity (CDEIS) were used for the clinical and endoscopic evaluation. Two tests were performed on the fecal samples, to check the levels of calprotectin and lactoferrin. The performance of these fecal markers for detection of inflammation with reference to endoscopic and histological inflammatory activity was assessed and calculated sensitivity, specificity, accuracy.A total of 52 patient's samples whose histological evaluations showed inflammation, 49 were lactoferrin-positive, and 40 were calprotectin-positive (p = 0.000). Lactoferrin and calprotectin findings correlated with C-reactive protein in both the CD and UC groups (p = 0.006; p = 0.000), with CDAI values (p = 0.043; 0.010), CDEIS values in DC cases (p = 0,000; 0.000), and with MDAI values in UC cases (p = 0.000). CONCLUSION: Fecal lactoferrin and calprotectin are highly sensitive and specific markers for detecting intestinal inflammation. Levels of fecal calprotectin have a proportional correlation to the degree of inflammation of the intestinal mucosa.

RESUMO

O diagnóstico das doenças inflamatórias intestinais (DII) depende de um conjunto de dados da história clínica, dos achados de exame físico, dos testes laboratoriais, e de procedimentos endoscópicos e radiológicos. Na última década houve um grande avanço no tratamento das DII. O uso de imunossupressores, além dos corticóides, assumiu um papel rotineiro no cuidado ao paciente. Ainda, no fim do século, tivemos um progresso sem precedentes no melhor conhecimento da patogênese da colite ulcerativa e doença de Crohn. Paralelo a isso, a biotecnologia permitiu o desenvolvimento de novos agentes terapêuticos com ação estratégica em alvos específicos do processo patogênico da doença. Esta revisão cobre, além do diagnóstico, os agentes rotineiramente utilizados no tratamento das DII e procura dar uma visão geral sobre as terapias emergentes.

RESUMO

RACIONAL - OBJETIVO: Avaliar a eficácia do infliximab no tratamento de pacientes com doença de Crohn ativa ou com fístulas. MÉTODOS: Quarenta e quatro portadores de doença de Crohn, refratários ao tratamento convencional, foram tratados com infliximab, na dose de 5 mg/kg, através de infusão endovenosa. RESULTADOS: Trinta deles (68,2 por cento) obtiveram melhora dos sintomas, com regressão importante nos níveis de atividade da doença, medidos pelo CDAI (Crohn's Disease Activity Index). Oito (57,1 por cento) de 14 portadores de fístulas também obtiveram bons resultados, com fechamento ou importante diminuição do fluxo destas. A tolerância à droga foi boa em todos os casos. CONCLUSAO: O uso de infliximab nestes casos parece ser boa opção terapêutica, com baixos índices de efeitos colaterais.

RESUMO

AIM: To evaluate the efficacy of infliximab in the treatment of patients with active Crohn's disease or with fistulas. METHODS: Forty four patients with Crohn's disease, resistant to conventional therapies, were treated with 5 mg/kg endovenous infliximab infusions. RESULTS: Thirty of them (68.2%) improved, with important reduction on disease activity levels, measured by the CDAI (Crohn's Disease Activity Index). Eight (57.1%) of 14 patients with fistulas also showed good results, with closure or important reduction in their flow. The drug was well tolerated in all cases. CONCLUSION: The use of infliximab in these cases seems to be a good therapeutic option, with low rates of side effects.

RESUMO

O diagnóstico sorológico da doença inflamatoria tem sido sugerido, por diversos autores, como uma alternativa para diferenciar retocolite ulcerativa da doença de crohn através da determinaçao pareada do teste do ASCA E ANCA. No presente trabalho apresentam-se os resultados obtidos em 70 pacientes encaminhaos ao LID Laboratorio para a execuçao de ambos os ensaios. A determinaçao do ASCA apresentou senssibilidade de 80por cento na doença de Crhon, confirmado os resultados publicados nos últimos dois anos na literatura internacional. A interpretaçao deve ser feita com cautela, pois títulos baixos podem ser encontrados em pequeno número de casos de retocolite ulcerativa e em menor grau na doença celíaca
