BACKGROUND: Adalimumab is a monoclonal antibody, tumor necrosis factor-alpha (TNFα) inhibitor that has efficacy for inducing and maintaining remission in moderate-to-severe ulcerative colitis. Real world studies with adalimumab in Latin American ulcerative colitis patients are scarce. OBJECTIVE: To assess the clinical remission rates in induction and maintenance with adalimumab therapy in ulcerative colitis. METHODS: Observational, multicenter and retrospective study on a case series of patients with moderate-to-severe ulcerative colitis under adalimumab therapy. The variables analyzed were: demographic data, previous infliximab status, concomitant drugs, the Montreal Classification, disease activity (Mayo score) at weeks 0, 8, 26 and 52, or until the last follow-up. Clinical remission was defined as a partial Mayo score ≤2 and Last observation carried forward (LOCF) and Non responder imputation (NRI) analysis were used. RESULTS: Thirty-six patients were included in the study. With LOCF analysis, remission rates at weeks 8, 26 e 52 were of 41.7%, 47.2% and 47.2%, respectively. With NRI analysis, remission rates at weeks 8, 26 and 52 were of 41.7%, 41.7% and 27.8%, respectively. CONCLUSION: Adalimumab was effective in the treatment of moderate-to-severe ulcerative colitis. Clinical remission was observed in approximately 40% of the patients at weeks 8 and 26, and in almost a quarter of the patients after 1 year of follow up. RESUMO CONTEXTO: O adalimumabe é um anticorpo monoclonal, inibidor do TNF alfa, que tem eficácia comprovada na indução e manutenção da remissão na retocolite ulcerativa inespecífica moderada à severa. Há escassez de dados sobre o uso do adalimumabe na retocolite ulcerativa inespecífica em pacientes latino-americanos. OBJETIVO: Analisar as taxas de remissão clínica na indução e manutenção do tratamento da retocolite ulcerativa inespecífica com adalimumabe. MÉTODOS: Estudo observacional, multicêntrico e retrospectivo de uma série de casos de portadores de retocolite ulcerativa inespecífica moderada à grave que utilizaram adalimumabe. Variáveis analisadas: dados demográficos, uso prévio de infliximabe, medicações concomitantes, Classificação de Montreal, atividade da doença (escore parcial de Mayo) nas semanas 0, 8, 26 e 52, ou até o maior tempo de seguimento atingido. Remissão clínica foi definida como escore parcial de Mayo ≤2 e foi avaliada pelos métodos. Abordagem com base na observação mais recente (LOCF) e Imputação de não respondedores (NRI). RESULTADOS: Trinta e seis pacientes foram incluídos no estudo. Pela análise LOCF, as taxas de remissão nas semanas 8, 26 e 52 foram de 41,7%, 47,2% e 47,2%, respectivamente. Pela análise NRI, as taxas nas semanas 8, 26 e 52 foram de 41,7%, 41,7% e 27,8%, respectivamente. CONCLUSÃO: Adalimumabe foi eficaz no manejo da retocolite ulcerativa inespecífica moderada a grave. A remissão clínica foi observada em cerca de 40% dos pacientes nas semanas 8 e 26, e em cerca de 1/4 dos pacientes após 1 ano de seguimento.

Introduction: Ileocolic resection (ICR) is the most common surgical procedure performed for Crohn's disease (CD). Similarly, right-sided Colorectal cancer (CRC) is treated by the same operation. The primary aim of this study was to analyze and compare the frequency and profile of early postoperative complications of ICR between patients with CD and CRC. Methods: Retrospective and observational study with patients submitted to ICR from two Brazilian tertiary referral units in colorectal surgery. We included patients with diagnosis of CD or CRC, treated with ICR, at any stage of follow-up. Variables analyzed: age at surgery, gender, diagnosis, surgical approach (open or laparoscopy), type of anastomosis (hand-sewn/stapled; end-to-end/side-to-side), presence and type of early postoperative complications (30 days) and mortality, among others. Results: 109 patients were included, 73 with CD (67%) and 36 with CRC (33%). CD patients were younger (42.44 ± 12.73 years vs. 66.14 ± 11.02 years in the CRC groups, p

BACKGROUND: Infliximab and adalimumab are considered effective drugs in the management of Crohn’s disease. However, due to significant immunossupression, they can cause important adverse events, mostly infections. OBJECTIVE: The aim of this study was to quantify and describe adverse events derived from adalimumab and infliximab use in Crohn’s disease patients, and to compare the safety profile between these two agents. METHODS: This was an observational, single-center, longitudinal, retrospective study with Crohn’s disease patients under infliximab or adalimumab therapy. Variables analyzed: demographic characteristics (including the Montreal classification), type of agent used, concomitant immunomodulators, presence and types of adverse events observed. Patients were allocated in two groups (infliximab and adalimumab) and had their adverse events accessed and subsequently compared. RESULTS: A total of 130 patients were included (68 in infliximab and 62 in adalimumab groups, respectively). The groups were fully homogeneous in all baseline characteristics, with a median follow-up of 47.21±36.52 months in the infliximab group and 47.79±35.09 in the adalimumab group (P=0.512). Adverse events were found in 43/68 (63.2%) and 40/62 (64.5%) in each group, respectively (P=0.879). There were no differences between the groups regarding infections (P=0.094) or treatment interruption (P=0.091). There were higher rates of infusion reactions in the infliximab group (P=0.016). Cephalea and injection site reactions were more prevalent in adalimumab patients. CONCLUSION: Adverse events were found in approximately two thirds of Crohn’s disease patients under anti-TNF therapy, and there were no significant differences between infliximab or adalimumab. RESUMO CONTEXTO: A utilização de inibidores do fator de necrose tumoral (TNF) alfa no manejo da doença de Crohn é cada vez mais frequente. Tanto o infliximabe quanto o adalimumabe são considerados medicamentos efetivos no controle da doença. Entretanto, por serem potentes imunossupressores, podem causar efeitos adversos importantes, principalmente infecções. OBJETIVO: O objetivo primário deste estudo foi analisar a presença de efeitos adversos dos anti-TNFs em portadores de doença de Crohn, comparando-se infliximabe e adalimumabe e individualizando-se o perfil de segurança de cada droga. MÉTODOS: Estudo observacional, longitudinal e retrospectivo, que incluiu portadores de doença de Crohn com uso de infliximabe ou adalimumabe de uma coorte de pacientes tratados em um único centro. Analisou-se características demográficas (incluindo-se a classificação de Montreal), tipo de agente utilizado, presença e tipo dos eventos adversos observados, entre outras variáveis. Os pacientes foram alocados em dois grupos (infliximabe e adalimumabe) e tiveram os efeitos adversos anotados e posteriormente comparados. RESULTADOS: Um total de 130 pacientes foram incluídos (68 com infliximabe e 62 com adalimumabe). Os grupos foram homogêneos em todas as variáveis analisadas, com tempo de seguimento médio de 47,21±36,52 meses no grupo infliximabe e 47,79±35,09 no grupo adalimumabe (P=0,512). Efeitos adversos foram encontrados em 43/68 (63,2%) e 40/62 (64,5%) nos dois grupos, respectivamente (P=0,879). Não houve diferença entre os grupos em relação a infecções (P=0,094) ou interrupção do tratamento (P=0,091). Houve maiores índices de reações infusionais no grupo infliximabe (P=0,016). Cefaleia e reações no local das injeções foram mais frequentes no grupo adalimumabe. CONCLUSÃO: Efeitos adversos foram encontrados em cerca de dois terços dos pacientes com doença de Crohn em uso de anti-TNF, não havendo maiores diferenças em relação ao uso de infliximabe ou adalimumabe.

Ulcerative colitis [UC] patients have a known higher risk for development of colorectal cancer than the general population.1 Anal squamous cell carcinoma [ASCC] is an infrequent tumour, with an incidence of approximately 1–2/100000 among inflammatory bowel disease [IBD] patients.2,3 The incidence seems higher in Crohn’s disease [CD] than in UC. Fistulas and chronic wounds in perianal CD tend to be a risk factor for the development of ASCC, as are smoking, infection with human papilloma virus [HPV] and immunosuppression.4 We recently saw a 70-year-old lady with a previous diagnosis of UC [proctosigmoiditis] for 10 years. She was referred to our unit to initiate biological therapy, …

OBJECTIVE: To evaluate the acceptability of an educational project using A porcine model of airway for teaching surgical cricothyroidotomy to medical students and medical residents at a university hospital in southern Brazil.METHODS: we developed a teaching project using a porcine model for training in surgical cricothyroidotomy. Medical students and residents received lectures about this surgical technique and then held practical training with the model. After the procedure, all participants filled out a form about the importance of training in airway handling and the model used.RESULTS: There were 63 participants. The overall quality of the porcine model was estimated at 8.8, while the anatomical correlation between the model and the human anatomy received a mean score of 8.5. The model was unanimously approved and considered useful in teaching the procedure.CONCLUSION: the training of surgical cricothyroidotomy with a porcine model showed good acceptance among medical students and residents of this institution.
