Colitis ulcerosa en adolescente / An Adolescent with Ulcerative Colitis

Introducción: La colitis ulcerosa es una enfermedad inflamatoria intestinal de etiología multifactorial, que afecta principalmente al colon y al recto. Sus síntomas cardinales son diarrea crónica, rectorragia y dolor abdominal en cuadros severos. Su curso se caracteriza por periodos de remisión y de actividad llamados brotes, aunque en una menor proporción puede mostrar una actividad continua. Cuando afecta el recto, el colon izquierdo o más zonas se denomina pancolitis. La colonoscopia con biopsias múltiples es imprescindible para confirmar el diagnóstico y valorar la extensión de la enfermedad. Objetivo: Remarcar y promover el cuadro clínico que permita la sospecha diagnóstica de la colitis ulcerosa en el primer nivel de atención. Caso clínico: Paciente de 19 años de edad con antecedentes de diarrea crónica sanguinolenta, refractaria a varios tratamientos, que remitió por sí misma y que posteriormente recidiva con mayor severidad, lo que hace sospechar de una etiología atípica: colitis ulcerosa(AU)

Introduction: Ulcerative colitis (UC) is an inflammatory bowel disease (IBD) of multifactorial etiology that affects the colon and rectum. Its cardinal symptoms are diarrhea, rectal bleeding and abdominal pain(in severe cases). In its course alternate periods of remission and activity (flares), although in a minority it has continuous activity. The extension may affect the rectum, the left colon or even more zones (pancolitis). Colonoscopy with multiples biopsies is essential to confirm diagnosis and evaluate the extension of the disease. Objective: To publicize the clinical picture that allows the diagnostic suspicion of ulcerative colitis at the first level of care. Clinical case: We report a clinical case of a patient of 19 years old with a history of chronic bloody diarrhea refractory to various treatments, which remitted itself and later relapsed more severely, making suspicious of an atypical etiology: ulcerative colitis(AU)

Días de hospitalización por colitis ulcerosa y enfermedad de Crohn según sexo entre los años 2018-2021, Chile / Chile hospital length of stay due to ulcerative colitis and Crohn's disease according to sex between the years 2018-2021, Chile

Introducción: La enfermedad inflamatoria intestinal (EII), como la Enfermedad de Crohn (EC) y la Colitis Ulcerosa (CU), ha experimentado un aumento en las tasas de egreso hospitalario en países en vías de desarrollo, generando una carga adicional a los sistemas de salud y, por ende, mayores costos. Actualmente, en Chile, no se disponen de datos sobre la incidencia y prevalencia de estas enfermedades. Objetivo: Analizar las tasas de egreso hospitalario por CU y EC entre los años 2018-2021 en Chile según el Departamento de Estadística e Información en Salud (DEIS). Materiales y métodos: Estudio descriptivo, observacional y ecológico. Se utilizó una muestra de 9.109 sujetos, de todos los rangos etarios, hospitalizados con diagnóstico de EC y CU entre 2018-2021. La base de datos se obtuvo del DEIS. No se necesitó aprobación por comité de ética. Resultados: Entre los años 2018-2021, la tasa de egreso hospitalario de CU (9,08) fue mayor que la EC (3,88). Entre 2019-2020 se presentó la mayor caída de las tasas con un descenso de 1,10 para EC y 1,49 para CU. Las mujeres tuvieron una mayor tasa general en ambas enfermedades (4,15 para EC y 10,04 para CU). Las mujeres con EC presentaron una mayor estadía hospitalaria con un promedio de 8,69 días. Conclusión: Los resultados obtenidos actualizan la situación epidemiológica nacional respecto a los días de hospitalización por CU y EC, y podrían contribuir a cuantificar los costos de la EII para generar políticas de salud pública.

Introduction: In developing countries, Inflammatory Bowel Disease (IBD) such as Crohn's disease (CD) and ulcerative colitis (UC) has seen an increase in hospital discharge rates, causing an overload on healthcare systems and higher costs. Currently, in Chile, there is no available data on the incidence and prevalence of these diseases. Objective: This study aimed to analyze UC and CD hospital discharges in Chile between the years 2018-2021 according to the Department of Health Statistics and Information (DEIS). Materials and methods: Descriptive, observational, and ecological study. The sample included 9,109 subjects of all age ranges, hospitalized with CD and UC diagnoses between 2018-2021. The database was obtained from DEIS. Ethics committee approval was not required. Results: Between 2018-2021, the hospital discharge rate for UC was higher than for CD. The most significant rate drop occurred between 2019-2020, with a decrease of 1.10 for CD and 1.49 for UC. Women had the highest rates in both diseases (4.15 for CD and 10.04 for UC). Women with CD presented a longer hospital stay, with an average of 8.69 days. Conclusion: The obtained data provide updated information on the national epidemiological situation regarding hospital length of stay due to UC and CD, and could contribute to measuring IBD costs for the creation of public health policies.

Epidemiological study on the incidence of inflammatory bowel disease in Yinzhou District, Ningbo City from 2011 to 2020 / 北京大学学报(医学版)

OBJECTIVE@#To describe the distribution characteristics of inflammatory bowel disease among permanent residents in Yinzhou District, Ningbo City, and to understand the disease burden and development trend of inflammatory bowel disease in this area.@*METHODS@#Using the retrospective cohort design, we collected the registration information of all permanent residents in the residents' health files of the Yinzhou Regional Health Information Platform from 2010 to 2020, and used electronic medical records to follow up their inflammatory bowel disease visits. A one-year wash-out period was set, and the patients who were diagnosed with the primary diagnosis for the first time after one year of registration were re-garded as new cases. The incidence density and 95% confidence interval (CI) of inflammatory bowel disease were estimated by Poisson distribution.@*RESULTS@#From 2011 to 2020, a total of 1 496 427 permanent residents in Yinzhou District were included, of which 729 996 were male (48.78%). The total follow-up person-years were 8 081 030.82, and the median follow-up person-years were 5.41 [interquartile range (IQR): 5.29]. During the study period, there were 1 217 new cases of inflammatory bowel disease, of which males (624 cases, 51.27%) were more than females (593 cases, 48.73%). The total incidence density was 15.06/100 000 person-years (95%CI: 14.23, 15.93). Among all new cases, there were 1 106 cases (90.88%) of ulcerative colitis, with an incidence density of 13.69 per 100 000 person-years (95%CI: 12.89, 14.52); 70 cases (5.75%) of Crohn's disease, with an incidence density of 0.87 per 100 000 person-years (95%CI: 0.68, 1.09); and 41 cases (3.37%) of indeterminate colitis, with an incidence density of 0.51 per 100 000 person-years (95%CI: 0.36, 0.69). The median age of onset of ulcerative colitis was 50.82 years old (IQR: 18.77), with the highest proportion (15.01%) in the 45-49 years group. The incidence density of ulcerative colitis gradually increased with age, reaching a relatively high level in the 45-49 years group (20.53/100 000 person-years; 95%CI: 17.63, 23.78), followed by a slight increase. And the incidence density in the 65-69 years group was the highest (25.44/100 000 person-years; 95%CI: 20.85, 30.75), with a rapid decrease in the 75-79 years group. The median age of onset of Crohn's disease was 44.34 years (IQR: 33.41), with the highest proportion (12.86%) in the 25-29 years group. Due to the small number of new cases of Crohn's disease, the age distribution fluctuated greatly, with peaks both in young and old people. From 2011 to 2020, the incidence density of inflammatory bowel disease in Yinzhou District was at a low level from 2011 to 2013, and showed a rapid upward trend from 2014 to 2016, reaching a peak of 24.62 per 100 000 person-years in 2016 (95%CI: 21.31, 28.30), and slightly decreased in 2017-2020.@*CONCLUSION@#The incidence density of inflammatory bowel disease in Yinzhou District from 2011 to 2020 was at a relatively high level, and medical institutions and health departments need to pay attention to the burden of disease caused by it.

Aspectos epidemiológicos das doenças intestinais inflamatórias na região oeste do Estado de Minas Gerais / Epidemiologic aspects of inflammatory bowel disease in the western region of minas gerais state

ABSTRACT BACKGROUND: Crohn's disease (CD) and ulcerative colitis (UC), two of the main inflammatory bowel diseases (IBD), have been increasingly diagnosed in South America. Although IBD have been intensively studied in the last years, epidemiologic data in Brazil are scarce. OBJECTIVE: To study the clinical and epidemiologic profile of IBD patients treated in the Clinical Hospital of the Federal University of Uberlândia from 1999 to 2014. METHODS: We performed a retrospective study of the medical records of patients diagnosed with IBD, according to the international classification of diseases (ICD) - ICD K50 for CD and ICD K51 for UC - confirmed by endoscopic examination in the case of both diseases. We analyzed the following variables: age; sex; ethnicity; smoking habit; primary diagnosis; site of disease manifestation; main clinical manifestations; IBD-related complications; extraintestinal manifestations; and established drug and/or surgical treatment. RESULTS: We evaluated 183 IBD cases (91 UC and 92 CD cases). The estimated prevalence rate of UC was 15.06/100.000 inhabitants and of CD was 15.23/100.000. The CU and CD female to male incidence ratios were 1.7 and 1.8, respectively. The average age of patients diagnosed with UC was 39.4 years and of those diagnosed with CD was 31.1 years. White-skinned people were the most affected by UC (66.0%) and CD (69.0%). Few patients were submitted to surgical procedures as treatment alternative. CONCLUSION: The estimated prevalence of IBD in this population was low compared to that of populations of North America, but high compared to that of other regions considered to present low incidence, such as some Asian and Latin American countries.

RESUMO CONTEXTO: A doença de Crohn (DC) e a retocolite ulcerativa (RCU), duas das principais doenças inflamatórias intestinais (DIIs), têm sido cada vez mais diagnosticadas na América do Sul. Embora a DII tenha sido intensamente estudada nos últimos anos, os dados epidemiológicos no Brasil são escassos. OBJETIVO: Estudar o perfil clínico e epidemiológico dos pacientes com DII atendidos no Hospital das Clínicas da Universidade Federal de Uberlândia de 1999 a 2014. MÉTODOS: Foi realizado um estudo retrospectivo dos prontuários de pacientes com diagnóstico de DII, de acordo com a classificação internacional de doenças (CID) - CID K50 para DC e CID K51 para RCU - confirmado por exame endoscópico para ambas as doenças. Analisamos as seguintes variáveis: idade; sexo; etnia; hábito tabágico; diagnóstico primário; local de manifestação da doença; principais manifestações clínicas; complicações relacionadas a DII; manifestações extraintestinais; tratamentos medicamentoso e/ou cirúrgico instituídos. RESULTADOS: Foram avaliados 183 casos de DII (91 casos de RCU e 92 casos de DC). A prevalência estimada de RCU foi de 15,06/100.000 habitantes e de DC foi de 15,23/100.000. As taxas de incidência entre pacientes do sexo feminino e masculino foram de 1,7 para RCU e 1,8 para DC. A idade média dos pacientes com diagnóstico de RCU foi de 39,4 anos e daqueles com DC foi de 31,1 anos. A raça branca foi o grupo étnico mais afetado por RCU (66,0%) e DC (69,0%). Poucos pacientes foram submetidos a procedimentos cirúrgicos como alternativas de tratamento. CONCLUSÃO: A prevalência estimada de DII nesta população foi baixa em comparação com populações da América do Norte, mas elevada em comparação com outras regiões consideradas de baixa incidência, como alguns países da Ásia e da América Latina.

Colitis ulcerativa extensa severa presentación caso / Severe extensive ulcerative colitis. Case presentation

RESUMEN La colitis ulcerativa es una enfermedad crónica recidivante del tracto gastrointestinal, que evoluciona por recaídas formando parte de las enfermedades inflamatorias intestinales (EII). Afecta la mucosa y submucosa del colon, caracterizada por un proceso ulcerativo y supurado de la mucosa. La diarrea crónica con sangre es el síntoma más importante. En su curso alternan periodos de remisión y de crisis. No existe un criterio patognomónico para su definición, su diagnóstico se basa en una serie de criterios clínicos, endoscópicos e histológicos. Esta entidad infrecuente en su forma extensa severa. Aparece en un paciente, que llega a la institución de salud refiriendo que hace aproximadamente dos años, presenta cuadros de diarreas intermitentes con sangre, tratadas en el área de salud. Se le realizó Rx y colonoscopia constatando presencia de eritema, granularidad mucosa, friabilidad, pérdida de la vascularización submucosa, erosiones y ulceraciones extensas, profundas, signos de edema, pseudopólipos, pérdida de haustras, rigidez, sangrado, tractos fibrosos y presencia de exudado luminal. Se diagnosticó colitis extensa ulcerativa severa y se orientó tratamiento médico endovenoso y se continuó por via oral, obteniendo la remisión del cuadro clínico desde el punto de vista clínico y endoscópico (AU).

ABSTRACT Ulcerative colitis is a chronic recidivist disease of the gastrointestinal tract, evolving by relapses and is one of the intestinal inflammatory diseases. It affects the colon mucosa and sub-mucosa, characterized for an ulcerative process and mucosa exudation. Chronic diarrhea with blood is the most important symptom. Periods of crisis and remission alternated in its course; there is not a pathognomonic criteria for its definition and its diagnosis is based in a series of clinical, endoscopic and histological criteria. This entity, infrequent in extensive severe form, appears in a patient arriving to the hospital referring having intermittent diarrheas with blood for two years, treated in the health area. He undergone a radiography and colonoscopy, showing the presence of an erythema, mucosa granularity, friability, lost of submucosa vascularization, deep extensive erosions and ulcerations, edema signs, pseudo polyps, haustras lost, stiffness, bleeding, fibrous tracts and presence of luminal exudates. Severe ulcerative extensive colitis was diagnosed and was prescribed an endovenous medical treatment, continued orally, achieving the disease remission from the clinical and endoscopic point of view (AU).

Impacto do afastamento do trabalho por doenças inflamatórias intestinais no Brasil / Impact of work disability due to inflammatory bowel diseases in Brazil

As doenças inflamatórias intestinais (DII) podem ter impactos sociais e econômicos no Brasil, onde sua prevalência aumentou recentemente. Este estudo tem como objetivo principal avaliar a incapacidade por DII na população brasileira, descrevendo proporções com fatores demográficos e como objetivo secundário, a avaliação de possíveis fatores de risco de afastamento do trabalho por Doença de Crohn (DC) em um centro de referência em DII da Universidade do Estado do Rio de Janeiro (UERJ), cujo resultado pode refletir outras regiões do país. A análise foi realizada utilizando-se a plataforma do Sistema Único de Informações sobre Benefícios da Previdência Social, com um primeiro cruzamento de dados de auxílios doença e aposentadorias por invalidez com DC e Retocolite Ulcerativa (RCU) entre 2010-2014. Dados adicionais como valores médios de benefícios, duração do benefício, idade, sexo e região foram obtidos através da mesma plataforma. Um segundo cruzamento entre auxílios doença e aposentadorias por invalidez foi feito somente para DC entre 2010-2018 no estado do Rio de Janeiro e foram pesquisados os mesmos dados adicionais. Uma subanálise foi realizada nos casos de incapacidade em comum com os pacientes com DC da UERJ, para avaliação das características que teriam maior chance de atuar como fator de risco para afastamento do trabalho, se comparando com a população de DC desse ambulatório que não teve afastamento pelo Instituto Nacional do Seguro Social (INSS). No Brasil, a incapacidade temporária ocorreu com maior frequência na RCU enquanto a permanente na DC. A DC afastou pacientes mais jovens que a RCU e ambas mais mulheres que homens. As ausências temporárias do trabalho por DC e RCU foram maiores no Sul e as menores ausências por DC foram observadas no Norte e Nordeste. A média de dias de incapacidade foi longa, de quase um ano, sendo maiores na DC em comparação à RCU, porém ambos tenderam a diminuir de 2010 à 2014. O valor dos benefícios pagos pelas DII representou aproximadamente 1% de todos os benefícios da mesma natureza no país, sendo 51% dos gastos com DC. No RJ, a prevalência da DC foi de 26 por 100.000/habitantes, com custo indireto de 0,8% dos benefícios totais, apresentando taxa de 16,6% de incapacidade, similar a encontrada no grupo de pacientes da UERJ. Os fatores de risco de incapacidade por DC na UERJ foram idade menor que 40 anos a época do diagnóstico, tempo de duração da doença, cirurgia intestinal prévia e fístula anovaginal. Dos afastados, 19% apresentaram depressão ou ansiedade associados. A média de tempo entre o diagnóstico de DC e a incapacidade foi de 3 anos. No Brasil, as DII frequentemente causam incapacidade prolongada e podem gerar aposentadorias precoces, com programas de reabilitação profissional ainda pouco explorados. As tendências de redução das taxas de incapacidade no Brasil podem refletir melhorias no acesso a cuidados de saúde e a medicamentos. Os custos indiretos baseados apenas no absenteísmo em empregos foram significativos e a demonstração desse impacto socioeconômico e de fatores de risco de incapacidade podem auxiliar no planejamento de políticas públicas para o país.

Inflammatory bowel diseases (IBD) can lead to Brazil's social and economic impacts, where their prevalence has recently increased. This study's main objective is to evaluate the disability due to IBD in the Brazilian population describing proportions with demographic factors. Secondly, it assesses possible risk factors of absence from work due to Crohn's disease (CD) in a referral center of IBD of the State University of RJ (UERJ), which results may reflect other regions of the country. The analysis was performed using the Unified Social Security Benefits Information System platform, with the first crossing of data on sickness benefits and disability pensions with CD and Ulcerative Colitis (UC) between 2010- 2014. Additional data, such as average benefit values, benefit duration, age, sex, and region of the country, were obtained through the same platform. A second crossing between sickness benefits and disability pensions was made only for CD between 2010-2018 in the state of Rio de Janeiro (RJ) for the evaluation of the same additional data. A subanalysis was made in cases of CD disability in common with patients at UERJ, to assess the characteristics that would have a greater chance as a risk factor for absence from work, compared to the population of CD of this clinic that had no disability by the Institute National Social Security (INSS). In Brazil, temporary disability occurred more frequently in the UC while the permanent one in CD. Disability occurred in patients with CD younger than UC and both more in women than in men. Temporary absences from work due to CD and UC were more significant in the South, and the lowest absences due to CD were observed in the North and Northeast. The average number of days of disability was long, almost one year, being higher in CD than in UC, but both tended to decrease from 2010 to 2014. IBD's benefits represented approximately 1% of all the benefits of sickness in the country, with 51% of DC spending. In RJ, the prevalence of CD was 26 per 100,000 / inhabitants, with an indirect cost of 0.8% of total benefits, with a rate of 16.6% of disability, similar to that found in the group of patients at UERJ. The risk factors for CD disability in UERJ were age under 40 at the time of diagnosis, duration of the disease, previous intestinal surgery, and anovaginal fistula. Of those on absence from work 19% had associated depression or anxiety. The average time between the diagnosis of CD and disability was three years. In Brazil, IBDs often cause prolonged disability and can lead to early retirements, with professional rehabilitation programs still little explored. Trends in the reduction of disability rates in Brazil may reflect improvements in access to healthcare and medicines. The indirect costs with IBD in Brazil, based only in absenteeism, were significant, and demonstrating this socioeconomic impact and risk factors for disability can help plan public policies for the country.

Deficiência de vitamina D entre pacientes com doença inflamatória intestinal na Argentina: um estudo transversal / Vitamin d deficiency among inflammatorybowel disease patients in argentina: a cross-sectional study

ABSTRACT BACKGROUND: An association has been established between low serum values of vitamin D and inflammatory bowel disease. There is a lack of evidence on whether this association is still observed in regions where sun exposure throughout the year is higher. OBJECTIVE: To compare the prevalence of vitamin D deficiency between inflammatory bowel disease patients and healthy controls. METHODS: Inflammatory bowel disease patients were consecutively enrolled as cases. Age and gender-matched healthy subjects who agreed to undertake a determination of serum vitamin D were enrolled as controls. Demographic features, medical treatment, need for hospital admission at diagnosis, steroid treatment, smoking, need for surgical treatment were evaluated as factors associated with vitamin D deficiency. RESULTS: Overall, 59 patients with a diagnosis of either Crohn's disease or ulcerative colitis were enrolled, as well as 56 controls. Median age was 41 years (19-79) and 56% were male. Vitamin D deficiency was observed in 66.1% of inflammatory bowel disease patients versus 21.42% of healthy controls (OR 7.15 (3.1-16.48), P=0.001). Among inflammatory bowel disease patients, male gender, disease duration, moderate-to-severe disease and hospital admission at the moment of diagnosis were found to be associated with vitamin D deficiency. On multivariate analysis, only longer disease duration [(OR 1.01 (1-1.06)] and hospital admission at diagnosis [(OR 5.63 (1.01-31.61)] were found to be significantly associated with the latter. CONCLUSION: Vitamin D deficiency was more frequent among inflammatory bowel disease patients. Longer disease duration and need for hospital admission at diagnosis were associated to vitamin D deficiency among these patients.

RESUMO CONTEXTO: Uma associação foi estabelecida entre os baixos valores séricos de vitamina D e doença inflamatória intestinal. Falta evidência se esta associação ainda é observada em regiões onde a exposição ao sol durante todo o ano é maior. OBJETIVO: Comparar a prevalência de deficiência de vitamina D entre pacientes com doença inflamatória intestinal e indivíduos controles saudáveis. MÉTODOS: Pacientes com doença inflamatória intestinal foram consecutivamente selecionados. Indivíduos saudáveis combinados da mesma idade e gênero que concordaram em fornecer uma determinação da vitamina D do soro foram considerados como controles. Características demográficas, tratamento médico, necessidade de admissão hospitalar no diagnóstico, tratamento de esteroides, tabagismo, necessidade de tratamento cirúrgico foram avaliados como fatores associados à deficiência de vitamina D. RESULTADOS: No geral, 59 pacientes com diagnóstico de doença de Crohn ou colite ulcerosa foram observados, bem como 56 controles. A idade mediana era de 41 anos (19-79) e 56% eram do sexo masculino. A deficiência de vitamina D foi observada em 66,1% dos pacientes com doença inflamatória intestinal versus 21,42% dos controles saudáveis (OR 7,15 (3.1-16.48), P=0,001). Entre os pacientes com doença inflamatória intestinal, sexo masculino, duração da doença, doença de moderada a severa e admissão hospitalar no momento do diagnóstico foram associados com a deficiência de vitamina D. Na análise multivariada, apenas a duração da doença [(OR 1; 1 (1-1,06)] e a admissão hospitalar no diagnóstico [(OR 5,63 (1,01-31,61)] foram encontradas significativamente associadas ao último. CONCLUSÃO: A deficiência de vitamina D foi mais frequente entre os pacientes com doença inflamatória intestinal. Maior duração da doença e necessidade de admissão hospitalar no diagnóstico foram associadas à deficiência de vitamina D entre esses pacientes.

Registro prospectivo durante un año de enfermedad inflamatoria intestinal en población pediátrica argentina / One-year prospective registry of inflammatory bowel disease in the Argentine pediatric population

Introducción. La enfermedad inflamatoria intestinal (EII) comprende la colitis ulcerosa (CU) y la enfermedad de Crohn (EC). Su diagnóstico es cada vez más frecuente en pediatría y la incidencia es desconocida en Argentina. El objetivo de este trabajo fue determinar la incidencia anual de EII en menores de 18 años de nuestro país, los aspectos epidemiológicos y las formas clínicas de presentación. Población y métodos. Estudio prospectivo, multicéntrico y observacional que abarcó todo el territorio nacional. Se incluyeron menores de 18 años con diagnóstico de EII de centros públicos y privados entre el 1/6/2012 y el 31/5/2013, a través de protocolo en la web. Resultados. Participaron 17 centros, y se registraron 50 pacientes en 10 centros. La incidencia fue 0, 4/100 000 < 18 años; EC, 20; CU, 25; y EII no clasificable, 5. Distribución según sexo: 26 varones y 24 mujeres. La edad media al momento del diagnóstico fue de 9, 7 años y la demora diagnóstica, de 16, 5 meses. Los síntomas y signos más frecuentes fueron diarrea crónica con sangre y/o moco, dolor abdominal y adelgazamiento. El retraso del crecimiento fue menor de lo esperado. Las manifestaciones extraintestinales se presentaron en el 24% en CU y en el 25% en EC. La localización más frecuente en EC fue ileocolónica, y, en CU, pancolónica. No se observó CU con formas graves. Conclusiones. La incidencia fue menor que la reportada por otros registros. Se considera conveniente la creación de un registro permanente, que no solo permita conocer la incidencia, sino también servir de apoyo a los centros referentes que diagnostican y tratan esta patología.

Introduction. Inflammatory bowel disease (IBD) includes ulcerative colitis (UC) and Crohn's disease (CD). IBD diagnosis has become increasingly common in pediatrics but its incidence is unknown in Argentina. The objective of this study was to determine the annual incidence of IBD in children and adolescents younger than 18 years in Argentina, its epidemiological aspects, and clinical presentations. Population and methods. Prospective, observational, multicenter study conducted in Argentina. Children and adolescents younger than 18 years from public and private facilities, diagnosed with IBD between June 1st, 2012 and May 31st, 2013 were included via a web protocol. Results. Seventeen sites participated in the study; 50 patients were recruited from 10 sites. IBD incidence was 0.4/100 000 among individuals <18 years; CD, 20; UC, 25; and idiopathic IBD, 5. Distribution by sex: 26 boys and 24 girls. Patients' mean age at diagnosis was 9.7 years, and delay in the diagnosis was 16.5 months. The most common symptoms and signs were chronic diarrhea with blood and/or mucus, abdominal pain, and weight loss. Growth retardation was less common than expected. Extraintestinal manifestations were observed in 24% of UC cases and in 25% of CD cases. The most common location of CD was the ileum and colon, and of UC was the entire colon (pancolonic). There were no cases with severe UC. Conclusions. The incidence was lower than that reported in other registries. We recommend the development of an ongoing registry, to establish the incidence of IBD, but also to serve as backup for referring facilities where this disease is diagnosed and treated.

Inflammatory bowel disease: outpatient treatment profile / Doença inflamatória intestinal: perfil do paciente em tratamento ambulatorial

ABSTRACT BACKGROUND Crohn’s disease and ulcerative colitis are the two major forms of inflammatory bowel disease. The incidence and prevalence of both conditions have increased and are progressively increasing. These diseases are frequently recurrent and clinically highly severe. In Brazil, the lack of epidemiological data related to such diseases has left these patients in a vulnerable state and contributed to increased morbidity. OBJECTIVE To describe the profiles of patients with inflammatory bowel disease treated in an outpatient service in Brazil. METHODS This descriptive, exploratory, and retrospective documentary study with a quantitative approach was performed in an outpatient treatment service for inflammatory bowel disease, at a university polyclinic located in Rio de Janeiro, Brazil, from May to July 2016. The study included 556 patients and was approved by the research ethics committee of the institution (CAAE no. 55179316.6.0000.5259/2016). RESULTS The data showed a high prevalence of inflammatory bowel disease in white female patients. Crohn’s disease was diagnosed in more patients than was ulcerative colitis; the ileocolon was the most commonly affected location in patients with Crohn’s disease. The stenotic phenotype was prevalent in patients with Crohn’s disease. CONCLUSION The prevalence of the stenotic phenotype in Crohn’s disease in relation to others demonstrates the need for further investigations in this field of study in Brazil. In conclusion, the data showed that the epidemiologic profile of the study population is similar to that published in the national and international literature.

RESUMO CONTEXTO A Doença de Crohn e a retocolite ulcerativa idiopática são as duas principais formas de doença inflamatória intestinal e possuem crescente incidência e prevalência, tendem a ser progressivas, cursam com recidivas frequentes e assumem formas clínicas de alta gravidade. No Brasil a escassez de dados epidemiológicos relacionados a tais agravos deixa essas pessoas em estado de vulnerabilidade e contribui para o aumento da morbidade. OBJETIVO Descrever o perfil dos pacientes portadores de doença inflamatória intestinal atendidos em um ambulatório de doenças inflamatórias intestinais do estado do Rio de Janeiro. MÉTODOS Trata-se de uma pesquisa documental retrospectiva, exploratória, descritiva em abordagem quantitativa, realizada de maio a julho de 2016, em uma policlínica universitária, localizada no Rio de Janeiro, em ambulatório de tratamento de doenças inflamatórias intestinais. O estudo foi aprovado pelo Comitê de Ética em Pesquisa da instituição CAAE: 55179316.6.0000.5259 /2016, e contou com 556 participantes. RESULTADOS Os dados revelam um predomínio das doenças inflamatórias intestinais, nos pacientes do sexo feminino, de cor branca. A doença de Crohn foi diagnosticada em um maior número de indivíduos em relação a retocolite ulcerativa idiopática. Os dados do perfil de localização intestinal mostram a região ileocolônica como mais afetada na doença de Crohn. Foi evidenciado predomínio do fenótipo estenosante na doença de Crohn. CONCLUSÃO O predomínio do fenótipo estenosante na doença de Crohn, evidencia a necessidade de estudos aprofundados sobre a temática no Brasil. No mais, os dados obtidos demonstram um perfil epidemiológico da população semelhante ao divulgado em estudos nacionais e internacionais.

Caracterización de pacientes con colitis ulcerosa atendidos en centro de nivel terciario / Characterization of patients with ulcerative colitis treated at tertiary center

Introducción: la colitis ulcerosa es una afección de la sociedad moderna y su frecuencia en los países desarrollados ha ido en aumento desde mediados del siglo XX. Objetivo: caracterizar a pacientes con colitis ulcerosa. Métodos: se realizó un estudio descriptivo de corte transversal a 176 pacientes, con una edad media de 41,1 ± 14,5 años y colitis ulcerosa, atendidos en el Instituto de Gastroenterología desde enero 2011 hasta diciembre 2012. Resultados: se halló predominio del sexo femenino y el color de la piel blanca, mayor número de pacientes no fumadores y localización de la colitis hacia zona más distal del colon. Los síntomas más frecuentes fueron las diarreas con flemas y el sangrado rectal; mientras que las estenosis y el cáncer, al nivel de colon, y las alteraciones articulares y hepatobiliares, al nivel extracolónico, resultaron las complicaciones predominantes. El tratamiento medicamentoso más utilizado fue azulfidina, mesalazina y prednisona, por vía oral. Las causas más frecuentes de tratamiento quirúrgico fueron la estenosis y el cáncer colorrectal; las de muerte, el cáncer colorrectal y el colangiocarcinoma. Conclusiones: la colitis ulcerosa requiere especial atención por un equipo multidisciplinario y la familia, a partir del conocimiento de la enfermedad y sus complicaciones(AU)

Introduction: ulcerative colitis is a pathology of the modern society, and its frequency in developed countries has been growing since the middle of twenty century. Objective: characterize patients with ulcerative colitis. Methods: a transversal study was conducted in 176 patients with ulcerative colitis who are treated at Gastroenterology Institute from January 2011 to December 2012. Results: predominance of females and white skin color subjects was found, as well as higher number of nonsmoking subjects, the most frequent location of colitis was toward the distal colon area. The most common symptoms were diarrhea with mucus and rectal bleeding; but stenosis and cancer at colon level, joint disorders and hepatobiliary at extracolonic level were the predominant complications. The most widely used drug treatment was Azulfidine, mesalazine and prednisone orally. The most common causes of surgical treatment were stenosis and colorectal cancer. The most common cause death were colorectal cancer and cholangiocarcinoma. Conclusions: ulcerative colitis require special care by a multidisciplinary team and family, from knowledge of the disease and its complications(AU)

INFLAMMATORY BOWEL DISEASE IN HISPANIC COMMUNITIES: a concerted South American approach could identify the aetiology of Crohn’s disease and ulcerative colitis / Doença inflamatória intestinal nas comunidades Hispânicas: uma orquestrada abordagem Sul-Americana poderia identificar a etiologia da doença de Crohn e da retocolite ulcerativa

Despite intensive research we remain ignorant of the cause of both Crohn’s disease and ulcerative colitis. The dramatic rise in incidence, particularly of Crohn’s disease, points towards environmental factors as playing a significant role. A major purpose of this review is to stimulate a co-ordinated international effort to establish an on-going data base in Central and South America in which new cases are registered and through which investigations into aetiology can be conducted. In both Brazil and Mexico there is evidence that the incidence of ulcerative colitis is increasing, as also is the case for Crohn’s disease in Brazil. The pattern of disease is, therefore, directly comparable to that reported from Europe and the USA during the 1970s and 1980s, but much lower than contemporary data from Spain. Although the incidence is similar to that reported from Portugal, the studies from Almada and Braga were conducted a decade before that from Sao Paulo. The situation in Brazil compares dramatically with Uruguay and Argentina where the reported incidence of inflammatory bowel disease is significantly less. However, with growing industrialisation it is likely that there will be an explosion of inflammatory bowel disease in some areas of Central and South America over the next 20 years. The creation of a network of researchers across South and Central America is a real possibility and through a Concerted Action there is the possibility that major strides could be made towards understanding the cause of inflammatory bowel disease and so develop preventive strategies. .

Apesar da pesquisa intensa, ainda permanecemos ignorantes quanto à causa da doença de Crohn e da retocolite ulcerativa. O aumento dramático da incidência, particularmente da doença de Crohn, aponta para fatores ambientais desempenhando um papel significativo. Um grande propósito desta revisão é estimular um esforço internacional coordenado para estabelecer uma base de dados em curso na América Central e do Sul, na qual novos casos são registrados e através dos quais investigações sobre a etiologia seriam realizadas. No Brasil e no México, há evidências de que a incidência da colite ulcerosa está aumentando, como também é o caso da doença de Crohn no Brasil. O padrão da doença é, portanto, diretamente comparável àquela relatada da Europa e dos Estados Unidos durante a década de 1970 e 1980, mas muito mais baixa do que dados contemporâneos da Espanha. Embora a incidência seja semelhante à relatada a partir de Portugal, os estudos de Almada e Braga ocorreram uma década antes do que em São Paulo. A situação no Brasil compara-se dramaticamente com Uruguai e Argentina, onde a incidência relatada de doença inflamatória intestinal é significativamente menor. No entanto, com a crescente industrialização é provável que haja uma explosão de doença inflamatória intestinal em algumas áreas da América Central e do Sul nos próximos 20 anos. A criação de uma rede de pesquisadores em toda a América Central e do Sul é uma possibilidade real e, através de uma ação articulada, há a possibilidade de que grandes avanços poderiam ser feitos no sentido de compreender a causa da doença inflamatória intestinal e então desenvolverem-se estratégias preventivas. .

Anemia in inflammatory bowel disease: prevalence, differential diagnosis and association with clinical and laboratory variables / Anemia na doença inflamatória intestinal: prevalência, diagnóstico diferencial e associação com variáveis clínicas e laboratoriais

CONTEXT AND OBJECTIVES: Anemia is the most frequent extraintestinal complication of inflammatory bowel disease. This study aimed to: 1) determine the prevalence of anemia among patients with inflammatory bowel disease; 2) investigate whether routine laboratory markers are useful for diagnosing anemia; and 3) evaluate whether any association exists between anemia and clinical/laboratory variables. DESIGN AND SETTING: Cross-sectional at a federal university. METHODS: 44 outpatients with Crohn's disease and 55 with ulcerative colitis were evaluated. Clinical variables (disease activity index, location of disease and pharmacological treatment) and laboratory variables (blood count, iron laboratory, vitamin B12 and folic acid) were investigated. RESULTS: Anemia and/or iron laboratory disorders were present in 75% of the patients with Crohn's disease and in 78.2% with ulcerative colitis. Anemia was observed in 20.5% of the patients with Crohn's disease and in 23.6% with ulcerative colitis. Iron-deficiency anemia was highly prevalent in patients with Crohn's disease (69.6%) and ulcerative colitis (76.7%). Anemia of chronic disease in combination with iron deficiency anemia was present in 3% of the patients with Crohn's disease and in 7% of the patients with ulcerative colitis. There was no association between anemia and disease location. In ulcerative colitis, anemia was associated with the disease activity index. CONCLUSIONS: Most patients present iron laboratory disorders, with or without anemia, mainly due to iron deficiency. The differential diagnosis between the two most prevalent types of anemia was made based on clinical data and routine laboratory tests. In ulcerative colitis, anemia was associated with the disease activity index. .

CONTEXTO E OBJETIVOS: Anemia é a mais frequente complicação extraintestinal na doença inflamatória intestinal. Este estudo objetivou: 1) determinar a prevalência de anemia em portadores de doença inflamatória intestinal; 2) investigar se os marcadores laboratoriais de uso rotineiro são úteis para o diagnóstico da anemia; 3) avaliar se existe associação entre anemia e variáveis clínico-laboratoriais. TIPO DE ESTUDO E LOCAL: Estudo transversal em uma universidade federal. MÉTODOS: Foram avaliados 44 pacientes ambulatoriais com doença de Crohn e 55 com retocolite ulcerativa. Foram investigados aspectos clínicos (índice de atividade da doença, localização da doença e tratamento farmacológico) e laboratoriais (hemograma, ferrocinética, vitamina B12 e ácido fólico). RESULTADOS: Anemia e/ou anormalidades na ferrocinética estavam presentes em 75% dos pacientes com doença de Crohn e em 78,2% dos pacientes com retocolite. Anemia foi observada em 20,5% do grupo com doença de Crohn e em 23,6% do grupo com retocolite. Anemia por deficiência de ferro predominou entre os pacientes com doença de Crohn (69,6%) e com retocolite (76,7%). Anemia de doença crônica associada à anemia ferropriva estava presente em 3% dos pacientes com doença de Crohn e em 7% daqueles com retocolite. Na retocolite, a anemia estava associada com o índice de atividade da doença. CONCLUSÕES: A maioria dos pacientes apresentava alterações na ferrocinética com ou sem anemia, principalmente decorrente da ferropenia. O diagnóstico diferencial entre os dois tipos mais prevalentes de anemia foi baseado nos dados clínicos e nos testes laboratoriais de rotina. Anemia estava associada com o índice de atividade na retocolite. .
