ABSTRACT

La enfermedad inflamatoria intestinal (EII), cuyos fenotipos más frecuentes son la enfermedad de Crohn (EC) y la colitis ulcerosa (CU), tiene una etiología multifactorial, que resulta de la interacción de factores genéticos, ambientales y del microbioma. Su incidencia ha aumentado en las últimas décadas, así como también lo ha hecho la occidentalización de la dieta: alta en grasas, carbohidratos refinados, azúcar, carnes rojas y alimentos procesados. Una dieta occidental es considerada como factor de riesgo para el desarrollo de EII, ya que está asociada a disbiosis, alteración de la barrera intestinal y de la inmunidad del huésped. Existen diversas dietas de eliminación que podrían ejercer un rol en la inducción/mantención de la remisión. Sin embargo, la mayoría requiere estudios de mejor calidad científica para poder recomendarlas. A su vez, existen suplementos nutricionales que estarían asociados a la incidencia y curso de la enfermedad. El objetivo de esta revisión es mostrar el posible rol de la dieta en la incidencia de la EII, y las estrategias dieto-terapéuticas, incluyendo suplementos específicos y nutrición enteral, considerando periodos de crisis y remisión.


Inflammatory bowel diseases (IBD), most frequent phenotypes Crohn's disease and Ulcerative colitis, have a multifactorial etiology, resulting from genetics, environmental triggers and microbiome alterations. Its incidence has been increasing as well as the western diet, high in fat, refined carbohydrates, sugar, red meat and processed foods. A western diet is considered a risk factor for the development of IBD, since it is associated with dysbiosis, alteration of the intestinal barrier and host immunity. There are several elimination diets that could play a role in induction/maintenance of remission. However, most of them require better quality scientific studies. Also, there are nutritional supplements associated with the incidence and evolution of the disease. The aim of this review is to show the possible role of the diet in the incidence, and diet-therapeutic strategies, including specific supplements and enteral nutrition, considering periods of active disease and remission

ABSTRACT

La pandemia causada por el virus SARS-CoV-2, originada en Wuhan, capital de la provincia de Hubei (China), se ha convertido en un desafío para la humanidad. Es un virus altamente contagioso; hasta el momento, la enfermedad por coronavirus (COVID-19) presenta una mortalidad global alrededor del 6 %, que es mayor en pacientes con comorbilidades. La enfermedad inflamatoria intestinal (EII) es una patología discapacitante, con daño tisular y alteración en la respuesta inmunológica, lo cual, asociado a los medicamentos inmuno-supresores que se utilizan frecuentemente para su tratamiento, pone al paciente en riesgo de desarrollar infecciones y complicaciones. En esta revisión consideramos la interacción del virus SARS-CoV-2 con el tracto gastrointestinal y los potenciales mecanismos por los cuales un paciente con EII podría tener un riesgo incrementado de la infección por COVID-19. Adicionalmente, y a pesar de que no hay estudios clínicos pu-blicados en pacientes con EII y COVID-19, damos recomendaciones basadas en opinión de expertos sobre el cuidado de pacientes con EII, con énfasis en su tratamiento y la realización segura de procedimientos endoscópicos, tanto para el paciente como para el personal de salud.

The pandemic caused by the SARS-Cov-2 virus originating in Wuhan, capital of the province of Hubei (China), has become a challenge for humanity. It is a highly contagious virus and up to now the COVID-19 disease has an overall mortality of around 6 %, which is higher in patients with comorbidities. Inflammatory bowel disease (IBD) is a disabling pathology, with tissue damage and impaired immune response, which, associated with immunosuppressive drugs that are frequently used for their treatment, put the patient at risk of developing infections and complications. In this review we consider the interaction of the SARS-CoV-2 virus with the gastrointestinal tract and the potential mechanisms whereby a patient with IBD could have an increased risk of COVID-19 infection. Additionally, and despite the fact that there are no published clinical studies in patients with IBD and COVID-19, we make recommendations based on the opinion of experts on the care of patients with IBD, with an emphasis on its treatment and the safe performance of endoscopic procedures, both for the patient and the health personnel.

ABSTRACT

ABSTRACT Objective: Numerous factors may contribute as triggers to the exacerbation of the condition of patients with inflammatory bowel disease. Methods: The medical files of 109 patients with the positive history of inflammatory bowel disease exacerbation between March 2016 and March 2017 were assessed retrospectively. Data were obtained using the inflammatory bowel disease data bank software. The parameters were obtained from the inflammatory bowel disease data bank software. The mentioned parameters were assessed in terms of type and severity of disease using chi-square test in SPSS software. Moreover, binary logistic regression test was used to assess the associations between season of disease onset and inflammatory bowel disease exacerbation as odds ratios with 95% confidence intervals (95% CI). Results: Overall, (88.1%) of cases with inflammatory bowel disease exacerbation, had ulcerative colitis. The mean age of patients was 38.14 ± 14.66 years. The disease duration in all patients (ulcerative colitis and Crohn's disease) was 35.43 and 38.85 months, respectively. About 50% of patients with infection were strongyloides stercoralis positive. The occurrence of mild inflammatory bowel disease exacerbation was significantly higher in spring in comparison to other seasons (OR = 3.58; 95% CI 0.1-1.04). Most patients with ulcerative colitis were prescribed salicylates alone (53.12%). Most patients with Crohn's disease with mild and severe activity were non-smokers (p = 0.058). This difference was marginally significant. Conclusion: It is suggested that in future studies, the evidences of distribution of SS infections among patients with inflammatory bowel disease and the history of exacerbation along with other environmental factors such as enhancing nutritional quality and surface water be taken into consideration.


RESUMO Objetivo: Em pacientes com doença inflamatória intestinal, vários fatores podem servir como gatilhos para a exacerbação do quadro. Métodos: Os prontuários de 109 pacientes com história de exacerbação da doença inflamatória intestinal entre março de 2016 e março de 2017 foram avaliados retrospectivamente. Os dados foram obtidos usando o software do banco de dados sobre doença inflamatória intestinal, que também foi usado para a definição dos parâmetros do estudo. Esses parâmetros foram avaliados quanto ao tipo e severidade da doença usando o teste do qui-quadrado no software SPSS. Além disso, o teste de regressão logística binária foi utilizado para avaliar as associações entre a estação do início da doença e a exacerbação da doença inflamatória intestinal, expressados em razão de probabilidade (odds ratio) com intervalos de confiança de 95% (95% CI). Resultados: No geral, 88,1% dos casos de exacerbação da doença inflamatória intestinal foram observados em pacientes com colite ulcerativa. A média de idade dos pacientes foi de 38,14 ± 14,66 anos. Em todos os pacientes, a duração média da doença (colite ulcerativa e doença de Crohn) foi de 35,43 e 38,85 meses, respectivamente. Cerca de 50% dos casos de infecção apresentaram cultura positiva para Strongyloides stercoralis. A ocorrência de leve exacerbação da doença inflamatória intestinal foi significativamente maior na primavera em comparação com outras estações (OR = 3,58; 95% CI: 0,1-1,04). A maioria dos pacientes com colite ulcerativa foi medicada apenas com salicilatos (53,12%). A maioria dos pacientes com doença de Crohn com atividade classificada como leve ou grave era não fumante (p = 0,058). Essa diferença foi marginalmente significativa. Conclusão: Sugere-se que, em estudos futuros, as evidências de distribuição das infecções por Strongyloides stercoralis em pacientes com doença inflamatória intestinal e história de exacerbação sejam levadas em consideração em conjunto com outros fatores ambientais, como qualidade nutricional e da água de superfície.

ABSTRACT

Introdução: Pacientes com espondilite anquilosante podem apresentar-se com lesões inflamatórias intestinais, e, por isso, deve ser definido o uso da colonoscopia para tais pacientes. Objetivos: Avaliar as alterações colonoscópicas intestinais macroscópicas e achados histopatológicos microscópicos de pacientes com espondilite anquilosante; correlacionar os achados colonoscópicos e histopatológicos; e estudar a relação dos achados histopatológicos com as manifestações extra-articulares da doença, HLA-B27, BASFI and BASDAI. Métodos: Este é um estudo transversal de 22 pacientes com espondilite anquilosante. Os pacientes passaram por uma avaliação clínica, BASDAI e BASFI, coleta de sangue para determinação de HLA-B27, e colonoscopia com biópsia de quarto segmentos intestinais (íleo terminal, cólon direito, cólon sigmoide e reto). Resultados: Resultados colonoscópicos anormais foram obtidos em 13 (59,1%) pacientes, e a principal anormalidade foi a presença de pólipos intestinais. Os grupos de resultados colonoscópicos normais e anormais (n = 9 e n = 13, respectivamente) foram homogêneos no que diz respeito à idade, BASFI, BASDAI, e variáveis categóricas, e o valor P não revelou diferença significativa entre grupos. Dos resultados histopatológicos, 81% tiveram uma biópsia anormal do íleo terminal, 90.9% tiveram uma biópsia anormal do cólon sigmoide, e a biópsia retal estava anormal em 86.4%. Os achados histopatológicos revelaram biópsias anormais em 81%, 90.9%, 90.9% e 86.4% para o íleo terminal, cólon direito, cólon sigmoide e reto, respectivamente. Os resultados histopatológicos não revelaram associação estatisticamente significativa com as manifestações ex...


Introduction: Patients with ankylosing spondylitis can have intestinal inflammatory lesions, thus the use of colonoscopy for such patients should be defined. Objectives: To assess the gross intestinal colonoscopic changes and microscopic histopathologic findings of patients with ankylosing spondylitis; to correlate the colonoscopic and histopathologic findings; and to study the relationship of the histopathologic findings with extra-articular manifestations of the disease, HLA-B27, BASFI and BASDAI. Methods: This is a cross-sectional study of 22 patients with ankylosing spondylitis. The patients underwent clinical assessment, BASDAI and BASFI application, blood collection for HLA-B27 measurement, and colonoscopy with biopsy of four intestinal segments (terminal ileum, right and sigmoid colons, and rectum). Results: Abnormal colonoscopic results were obtained in 13 (59.1%) patients, the major abnormality being intestinal polyps. The groups of normal and abnormal colonoscopic results (n = 9 and n = 13, respectively) were homogeneous regarding age, BASFI, BASDAI, and categorical variables, and the P-value showed no significant difference between groups. The histopathological findings revealed abnormal biopsies in 81%, 90.9%, 90.9% and 86.4% for terminal ileum, right colon, sigmoid colon, and rectum, respectively. The histopathologic results showed no statistically significant association with the extra-articular manifestations, BASFI, BASDAI and HLA-B27 positivity. Conclusions: The histological analysis of the four intestinal segments evidenced inflammatory lesions in patients with normal and abnormal colonoscopic results, independently of bowel symptomatology and therapy used in the treatment of the basal disease. .

ABSTRACT

Inflammatory bowel disease (IBD), which includes Crohn's disease (CD) and ulcerative colitis (UC), is a chronic disorder that affects thousands of people around the world. These diseases are characterized by exacerbated uncontrolled intestinal inflammation that leads to poor quality of life in affected patients. Although the exact cause of IBD still remains unknown, compelling evidence suggests that the interplay among immune deregulation, environmental factors, and genetic polymorphisms contributes to the multifactorial nature of the disease. Therefore, in this review we present classical and novel findings regarding IBD etiopathogenesis. Considering the genetic causes of the diseases, alterations in about 100 genes or allelic variants, most of them in components of the immune system, have been related to IBD susceptibility. Dysbiosis of the intestinal microbiota also plays a role in the initiation or perpetuation of gut inflammation, which develops under altered or impaired immune responses. In this context, unbalanced innate and especially adaptive immunity has been considered one of the major contributing factors to IBD development, with the involvement of the Th1, Th2, and Th17 effector population in addition to impaired regulatory responses in CD or UC. Finally, an understanding of the interplay among pathogenic triggers of IBD will improve knowledge about the immunological mechanisms of gut inflammation, thus providing novel tools for IBD control.

ABSTRACT

Advances in sequencing technology and the development of metagenomics have opened up new ways to investigate the microorganisms inhabiting the human gut. The intestinal microbiota confer protection against pathogens, contribute to the maturation of the immune system, and regulate host metabolism. The composition of gut microbiota in early life is influenced by mode of birth, diet, and antibiotics. Decreased biodiversity and alterations in the composition of the intestinal microbiota have been observed in many diseases including obesity, neonatal necrotizing enterocolitis, inflammatory bowel disease, and recurrent Clostridium difficile infection. Therapeutic options for the diseases linked to imbalance in the microbiota include modifying the gut microbiota through diet, probiotics, and fecal transplants.

ABSTRACT

OBJETIVO: O objetivo deste estudo é demonstrar a importância da enterografia por tomografia computadorizada (entero-TC) e como este exame pode contribuir na elucidação diagnóstica e avaliação clínica de pacientes com doenças do intestino delgado. MATERIAIS E MÉTODOS: Análise retrospectiva de 35 pacientes submetidos a entero-TC realizadas em aparelho multidetector de 16 canais, entre maio de 2008 e março de 2009. Utilizou-se meio de contraste iodado venoso e oral neutro (polietilenoglicol). As principais indicações foram avaliação de doença de Crohn, diarreia de origem indeterminada e suspeita de neoplasias. RESULTADOS: Houve boa correlação dos achados à entero-TC relacionados à atividade da doença em pacientes com doença de Crohn, quando comparados com dados clínicos, laboratoriais e endoscópicos. Em 15 casos identificaram-se alterações compatíveis com doença de Crohn, 9 deles sugerindo atividade. Dos pacientes com diarreia, o exame elucidou a maioria dos casos. Identificaram-se dois casos de tumor carcinoide. CONCLUSÃO: A entero-TC é método simples e eficaz para estudo das doenças inflamatórias/neoplásicas do intestino delgado, sobretudo na avaliação da doença de Crohn, indicando atividade da doença. Uma de suas principais vantagens é a possibilidade de avaliação de alterações mesentéricas e extraintestinais associadas.


OBJECTIVE: The present study was aimed at demonstrating the value of computed tomography enterography (CT enterography) and how this imaging method can be useful in the diagnostic elucidation and assessment of patients with small bowel diseases. MATERIALS AND METHODS: Retrospective evaluation of 35 patients submitted to CT enterography in a 16-row multidetector CT equipment from May/2008 to March/2009. All the patients received intravenous and neutral oral iodinated contrast agents (polyethylene glycol). Main indications were: Crohn's disease, diarrhea of undetermined origin and suspicion of neoplasia. RESULTS: A good correlation was observed between CT enterography findings and clinical, laboratory and endoscopic data related to the disease activity in patients with Crohn's disease. In 15 cases alterations compatible with Crohn's disease were identified, nine of them suggesting disease activity. A diagnosis was achieved in the majority of the patients with diarrhea. Carcinoid tumors were identified in two patients. CONCLUSION: CT enterography is a simple and effective method in the evaluation of inflammatory/neoplastic small bowel diseases, particularly in cases of Crohn's disease, indicating disease activity. One of the main advantages of this method is the possibility of evaluating associated mesenteric and extraintestinal alterations.

ABSTRACT

La enfermedad inflamatoria intestinal (EII), se caracteriza por tener un proceso clínico impredecible. Se puede definir como la inflamación de la mucosa gastrointestinal de etiología desconocida. Se ha propuesto que resulta de una respuesta inmunitaria aberrante del huésped a los antígenos normales del tracto gastrointestinal. El diagnóstico se apoya en la evaluación integral de criterios clínicos, radiológicos, endoscópicos e histológicos. Pueden encontrarse síntomas digestivos y manifestaciones extraintestinales. El déficit de vitaminas y oligoelementos, juegan un papel importante en el estado nutricio de los pacientes con EII, afectando más a los pacientes con EC.


Inflammatory bowel disease (IBD) is characterized by an unpredictable clinical process. It can be defined as inflammation of the gastrointestinal mucosa of unknown etiology. It is proposed that results from an aberrant immune response to antigens of the host's normal gastrointestinal tract. The diagnosis is based on the comprehensive assessment of clinical, radiological, endoscopic and histologic findings. You can find digestive symptoms and extraintestinal manifestations. The deficit of vitamins and trace elements play an important role in the nutritional status of patients withIBD, affecting more patients with CD.

ABSTRACT

El comportamiento epidemiológico de las enfermedades inflamatorias intestinales (EII), ha variado en las últimas décadas. En áreas geografías de presentación infrecuente, como América latina, las tasas de incidencia y prevalencia han tenido un franco aumento. Se presume que este fenómeno, se debe a variables ambientales como la dieta, el tabaco, uso de ciertos medicamentos, la apendicectomía, estrés y algunos estilos de vida. La etiopatogenia de EII no esta completamente dilucidada por lo que actualmente se considera, que es de etiología multifactorial. Entre los factores implicados están: factores ambientales, familiares, genéticos y del sistema inmune. En esta revisión se exponen las características epidemiológicas de las EII, con énfasis en la población pediátrica. Así como también los principales factores ambientales de riesgo, que se relacionan con las EII. Se presentan también algunos mecanismos y condiciones tanto heredadas como adquiridas, que han sido involucrados en la etiopatogenia de las EII.

ABSTRACT

La presencia de aire en lugares del abdomen donde normalmente no tiene que haber aire representa, en general, un riesgo potencial de muerte para el paciente si no se hace un diagnóstico temprano y un manejo agresivo, ya sea médico o quirúrgico. El diagnóstico por imágenes juega un rol fundamental en estos casos. Las principales causas son la perforación de vísceras huecas y la producción de gas en procesos infecciosos. En general, el estudio de estos pacientes comienza con radiología o ecografía pero el método más sensible y específico es la TC, la que detecta muy bien la localización y la extensión del gas anormal.

ABSTRACT

La tomografía computada (TC) constituye un método de diagnóstico altamente sensible y específico para el diagnóstico de los procesos inflamatorios colónicos. La correcta identificación de los hallazgos tomográficos vinculados a enfermedad inflamatoria colónica es fundamental, ya que ello permite descartar la existencia de un proceso maligno subyacente y, por lo tanto, aplicar un tratamiento adecuado. Este trabajo describe los hallazgos tomográficos vinculados a Enfermedad Inflamatoria del Colon (EIC) así como las principales afecciones capaces de producir dicha entidad.

ABSTRACT

Edema is a consistent observation in inflamatory bowel disease (IBD), and immune responses are inevitable in inflammation. Because the lymphatic system is an integral part of both tissue fluid homeostasis and immune reactions, it is likely that lymphatics play a role in the complex etiology of IBD. Despite the consistent findings that the lymphatic system is altered during gastrointestinal inflammation, the majority of studies conducted on the disease only mention the lymphatic system in passing. The effects of inflammatory mediators on lymphatic vessel function also remain poorly defined, despite its essential role in immunity and prevention of tissue edema. Processes allowing effective lymph transport are altered during inflammation, however, the mode of alteration and reason why lymphatics are ineffective in inflammatory reactions need to be further investigated. In addition, these processes have not yet been examined in an appropriate animal model and little has been done using in vivo methods of investigation in any model of gastrointestinal inflammation. This paper reviews the role of the lymphatic system in intestinal inflammation, as well as the role of the inflammatory products in mediating lymphatic contractile function.

ABSTRACT

As doenças inflamatórias intestinais inespecíficas (OU) - Doença de Crohn (DC) e Retocolite Ulcerativa (RCU) - são caracterizadas por inflamação intestinal de caráter crônico e recidivante. A etiologia permanece, ainda, obscura, mas sabe-se que a imunorregulação anormal da mucosa intestinal constitui o ponto central para o início e perpetuação da inflamação. A resposta inflamatória sistêmica se manifesta em diferentes formas chamadas "extra-intestinais" como: pele, olhos, articulações e sistemas vascular, músculo-esquelético, respiratório, neurológico, urinário, entre outros. Os autores desse artigo se propõem a realizar uma revisão de tais manifestações

ABSTRACT

Dentre os vários aspectos epidemiológicos envolvendo pacientes com doença inflamatória intestinal, o tabagismo é o que apresenta associaçao mais consistente com sua ocorrência e evoluçao. A retocolite ulcerativa inespecífica é considerada doença de nao ou ex-fumantes, sugerindo-se que o tabagismo protegeria contra o seu desenvolvimento. Por outro lado, há referências de maior ocorrência de doença de Crohn em fumantes. Sessenta e oito pacientes com doença inflamatória intestinal (36 com retocolite ulcerativa inespecífica e 32 com doença de Crohn) foram analisados quanto ao sexo, idade, escolaridade, profissao, religiao e hábito tabágico. Cento e trinta e seis indivíduos dispépticos compuseram o grupo controle (dois controles/caso), selecionados por características demográficas similares. Todos os entrevistados foram subagrupados, segundo tabagismo, em fumantes, nao-fumantes e ex-fumantes. O questionário ainda avaliou sua relaçao com inicio e atividade da doença inflamatória intestinal e eventual proteçao adquirida, por exposiçao na infância, como, fumantes passivos. Tabagismo protegeu significativamente contra ocorrência de retocolite ulcerativa inespecífica (OR:0,30, P< O,03, IC: 95 por cento), o mesmo ocorrendo em relaçao à doença de Crohn (OR: O,81, P> O,5). Nao houve maior risco para o surgimento da doença de Crohn entre os fumantes desta amostra. Entre os ex-fumantes, 72,7 por cento desenvolveram retocolite ulcerativa inespecífica após interrupçao do tabagismo, contra 44,4 por cento na doença de Crohn.
