Clinical features of primary sclerosing cholangitis and inflammatory bowel disease / 中华内科杂志

Objective: To explore disease characteristics of primary sclerosing cholangitis (PSC) and inflammatory bowel disease (IBD) and compare the differences between PSC with and without IBD. Methods: Study design was cross sectional. Forty-two patients with PSC who were admitted from January 2000 to January 2021 were included. We analyzed their demographic characteristics, clinical manifestations, concomitant diseases, auxiliary examination, and treatment. Results: The 42 patients were 11-74(43±18) years of age at diagnosis. The concordance rate of PSC with IBD was 33.3%, and the age at PSC with IBD diagnosis was 12-63(42±17) years. PSC patients with IBD had higher incidences of diarrhea and lower incidences of jaundice and fatigue than in those without IBD (all P<0.05). Alanine aminotransferase, total bilirubin, direct bilirubin, total bile acid and carbohydrate antigen 19-9 levels were higher in PSC patients without IBD than in those with IBD (all P<0.05). The positive rates for antinuclear antibodies and fecal occult blood were higher in PSC patients with IBD than in those without IBD (all P<0.05). Patients with PSC complicated with ulcerative colitis mainly experienced extensive colonic involvement. The proportion of 5-aminosalicylic acid and glucocorticoid application in PSC patients with IBD was significantly increased compared with that of PSC patients without IBD (P=0.025). Conclusions: The concordance rate of PSC with IBD is lower at Peking Union Medical College Hospital than in Western countries. Colonoscopy screening may benefit PSC patients with diarrhea or fecal occult blood-positive for early detection and diagnosis of IBD.

Bilateral uveitis in silent ulcerative colitis: case report

Silent or subclinical inflammatory bowel diseases (IBD) is a relatively new term that has been used to describe individuals with asymptomatic active mucosal bowel inflammation, often unaware of their disease due to either the lack of or mild inflammatory symptoms. These patients are at risk for gastrointestinal and extra-gastrointestinal manifestations, with more advanced complications. In this article we intend to describe a case report of a patient with chronic history of many organ involvements including ocular, skin, and musculoskeletal, which was later placed under the umbrella of silent ulcerative colitis.

Postcolonoscopy colorectal cancer: an overview and future directions

Over the past decade, there has been a great interest in postcolonoscopy colorectal cancer (PCCRC). Its etiology is complex and multifactorial. Monitoring for PCCRC is even more complex. The strategies to decrease the incidence of PCCRC start by defining the problem, identifying the factors contributing to its development, followed by an attempt to define methods to decrease its incidence.We believe that the quality of the colonoscopy and the endoscopist's expertise are the key factors in decreasing the incidence of PCCRC.

Metabolic bone disease in children and adolescent patients with ulcerative colitis

Abstract Objective: Metabolic bone disease concerns a broad spectrum of conditions related to reduced bone density. Metabolic bone disease has been linked to chronic inflammatory diseases, such as ulcerative colitis. This study examines the prevalence of metabolic bone disease in ulcerative colitis patients and explores possible clinical predictors. Method: The authors performed a retrospective study involving children and adolescents with confirmed ulcerative colitis between January 2013 and December 2018. Bone density was evaluated through a dual-energy X-ray absorptiometry scan of the spine and total body. Osteoporosis was defined as a bone mineral density Z-score of <−2 and osteopenia as a Z-score of between −1.0 and −2. Results: A total of 37 patients were included in this analysis, with a mean age of 13.4 ± 3.9 years and a mean duration of illness of 2.1 ± 2.4 years. Using lumbar spine Z-scores and total body Z-scores, osteoporosis and osteopenia were identified by dual-energy X-ray absorptiometry scan measurements in 11 patients (29.7%) and 15 patients (40.5%), and in ten patients (27%) and 13 patients (35%), respectively. Lumbar spine Z-scores were significantly positively associated with male gender (B = 2.02; p = 0.0001), and negatively associated with the presence of extraintestinal manifestations (B = −1.51, p = 0.009) and the use of biologics (B = −1.33, p = 0.004). However, total body Z-scores were positively associated with body mass index Z-scores (B = 0.26, p = 0.004) and duration of illness in years (B = 0.35, p = 0.003). Conclusions: Metabolic bone disease is very common in this cohort of Saudi Arabian children and adolescents with ulcerative colitis and its occurrence appears to increase in female patients who suffer from extraintestinal manifestations.

Abstract Background: Chronic idiopathic ulcerative colitis (CIUC) is a disease with multifactorial chronic inflammation of the colonic mucosa. In Mexico, there are studies that show an increase in the frequency of new cases. The purpose of this work was to identify possible changes in CIUC behavior in a referral hospital. Methods: New ulcerative colitis (UC) cases confirmed by histopathology from January 2007 to December 2014 were included. Results: A total of 189 patients were included. Mean number of UC annual new cases was 23.6. The study included 95 male patients (50 %) and 94 female patients (50 %), with an average age of 44.6 years at diagnosis. The frequency of pancolitis was 77 %, in comparison with 59 % in the previous period. Extra-intestinal manifestations (EIM) were present in 55.8 % and colectomies in 5.2 %. Conclusion: Some characteristics of the disease have changed over time: there is an increased frequency of pancolitis and EIM, as well as a decrease in the rate of colectomies.

Ascitis en paciente con colitis ulcerativa como presentación de síndrome de Budd-Chiari: reporte de caso y revisión de la literatura / Ascites in a patient with ulcerative colitis presenting Budd-Chiari syndrome: case report and literature review

La enfermedad inflamatoria intestinal es una patología crónica en la que participa el sistema inmune, que puede acompañarse de manifestaciones extraintestinales en el hígado y vías biliares. El síndrome de Budd-Chiari se ha descrito previamente como una complicación rara de la colitis ulcerativa. Se describe el caso de una paciente joven con antecedente de colitis ulcerativa y trombosis venosa de miembro inferior, en manejo crónico con aminosalicilatos y anticoagulada durante 6 meses, quien debutó con cuadro clínico de ascitis de dos meses de evolución, con líquido ascítico de características hipertensivas, documentación imagenológica y biopsia hepática compatibles con síndrome de Budd-Chiari. Se presenta reporte de caso y revisión breve de la literatura.

Inflammatory bowel disease is a chronic disease involving the immune system, which can be accompanied by extraintestinal manifestations in the liver and biliary tract. Budd-Chiari syndrome has previously been described as a rare complication of ulcerative colitis. We describe the case of a young patient with a history of ulcerative colitis and venous thrombosis of the lower limb, under chronic management with aminosalicylates, and anticoagulation therapy for the past 6 months, who consulted with a 2-month history of ascites, with hypertension-related ascitic fluid, imaging analysis and liver biopsy compatible with Budd-Chiari syndrome. A case report and a brief literature review are presented.

Hemophagocytic lymphohistiocytosis as a presentation of inflammatory bowel disease / Linfohistiocitosis hemofagocítica como presentación de la enfermedad inflamatoria intestinal

Abstract Background: Hemophagocytic lymphohistiocytosis (HLH) is considered a medical emergency that should be recognized in patients with fever, splenomegaly, and progressive deterioration of the general condition. Laboratory findings include cytopenia, hypertriglyceridemia, hypofibrinogenemia, and hyperferritinemia. For HLH diagnosis, it is essential, although not mandatory, to perform a bone marrow biopsy. Given its nature, secondary causes of HLH should be sought, mainly infections, hemato-oncological disorders, autoimmune diseases, and auto-inflammatory conditions. Case report: We present the case of a female adolescent who presented with fever and lower gastrointestinal bleeding. Upon admission, acute liver failure and pancytopenia were documented. A bone marrow aspirate was performed, which revealed hemophagocytosis; other tests confirmed HLH diagnosis. During the diagnostic approach, inflammatory bowel disease was diagnosed. The patient received first-line treatment with an adequate response. Conclusions: Inflammatory bowel disease can be considered a cause of secondary HLH, particularly in patients with suggestive symptoms, such as digestive bleeding in the absence of other secondary causes of HLH.

Resumen Introducción: La linfohistiocitosis hemofagocítica (LHH) es considerada una urgencia médica que debe reconocerse en pacientes con deterioro progresivo del estado general, fiebre, pancitopenia y esplenomegalia. Los hallazgos de laboratorio incluyen citopenia, hipertrigliceridemia, hipofibrinogenemia e hiperferritinemia. Para su diagnóstico es importante, aunque no obligatoria, la realización de aspirado de médula ósea. Dada su naturaleza, se deben buscar causas secundarias de LHH, principalmente enfermedades infecciosas, hematooncológicas, autoinmunitarias y autoinflamatorias. Caso clínico: Se presenta el caso de una adolescente que inició con fiebre y sangrado digestivo bajo. A su ingreso, se documentó falla hepática aguda y pancitopenia. Se realizó aspirado de médula ósea y se encontró hemofagocitocis; el resto de los exámenes concluyeron LHH. Durante su abordaje se diagnosticó enfermedad inflamatoria intestinal. La paciente recibió tratamiento de primera línea con adecuada respuesta. Conclusiones: La enfermedad inflamatoria intestinal puede considerarse como una causa secundaria de LHH, en particular en pacientes con clínica sugestiva, como es el sangrado digestivo, en ausencia de otras causas secundarias de LHH.

Escala de autoavaliação Inflammatory Bowel Disease-Fatigue: tradução, adaptação cultural e propriedades psicométricas da versão Brasileira (IBD-F Brasil) / The inflammatory bowel disease-fatigue patient self-assessment scale: translation, cross-cultural adaptation and psychometric properties of the brazilian version (ibd-f brazil)

ABSTRACT BACKGROUND: Fatigue is a common symptom in patients with inflammatory bowel diseases (IBD). A translated and culturally adapted, instrument with robust psychometric for measuring fatigue in Brazilian patients with IBD is needed. OBJECTIVE: To translate and cross-culturally adapt the inflammatory Bowel Disease Fatigue Scale (IBD-F) into Brazilian-Portuguese and to test its measurement properties in Brazilian patients with IBD. METHODS: Data from 123 patients with IBD were collected. In addition to IBD-F, the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) was used. The measurement properties tested were: internal consistency, reproducibility (reliability and agreement), construct validity, internal and external responsiveness, and ceiling and floor effects. RESULTS: The Brazilian-Portuguese version of the IBD-F showed excellent internal consistency (Cronbach's alpha of 0.95), excellent reproducibility (ICC=0.97) and a minimal detectable change of 6.0 points. The construct validity was demonstrated with a good correlation between the IBD-F and FACIT-F (r=- 0.46). Effect sizes used for measuring internal responsiveness were moderate among those with Crohn's (0.66) disease and low in patients with ulcerative colitis (0.24). The Brazilian-Portuguese version of the IBD-F presented with high external responsiveness for Crohn's disease (0.84) and with low external responsiveness for ulcerative colitis (0.33). The area under the curve considered for responsiveness was 0.84. Twenty-five percent of floor effects and no ceiling effect were recorded. CONCLUSION: The Brazilian-Portuguese version of IBD-F has adequate measurement properties and its use can be recommended in clinical practice and research.

RESUMO CONTEXTO: A fadiga é um sintoma comum em pacientes com doenças inflamatórias intestinais (DII). Um instrumento de avaliação de fadiga traduzido, culturalmente adaptado e com psicometria robusta para medir a fadiga em pacientes brasileiros com DII é necessário. OBJETIVO: Traduzir e adaptar culturalmente a Inflammatory Bowel Disease Fatigue Scale (IBD-F) para o português do Brasil e testar suas propriedades de medida em pacientes brasileiros com DII. MÉTODOS: Foram coletados dados de 123 pacientes com DII. Além do IBD-F, foi utilizada a Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F). As propriedades de medida testadas foram: consistência interna, reprodutibilidade (confiabilidade e concordância), validade de construto, responsividade interna e externa e efeitos teto e chão. RESULTADOS: A versão em português do IBD-F mostrou excelente consistência interna (alfa de Cronbach de 0,95), excelente reprodutibilidade (ICC=0,97) e uma diferença mínima detectável de 6,0 pontos. A validade do construto foi demonstrada por meio de uma boa correlação entre o IBD-F Brasil e o FACIT-F (r= -0,46). Na análise de responsividade interna, os tamanhos de efeito obtidos foram moderado entre aqueles com doença de Crohn (0,66) e baixo em pacientes com colite ulcerativa (0,24). O IBD-F Brasil apresentou alta responsividade externa entre aqueles com doença de Crohn (0,84) e baixa responsividade externa em pacientes colite ulcerativa (0,33). A área sob a curva considerada para responsividade foi de 0,84. Foram registrados 25% de efeito chão e nenhum efeito teto nas avaliações realizadas. CONCLUSÃO: O IBD-F Brasil possui propriedades de medida adequadas e seu uso pode ser recomendado na prática clínica e na pesquisa em pacientes com DII.

Serão as bactérias cariogénicas o fator de risco maior para cáries dentárias em doentes com retocolite ulcerativa? / Are cariogenic bacteria the major risk factor to dental caries in patients with ulcerative colitis?

ABSTRACT BACKGROUND: High prevalence of dental caries in ulcerative colitis (UC) has been attributed to diet and changes in salivary environment. OBJECTIVE: We aimed to characterize the prevalence of dental caries, salivary flow rates, salivary buffering capacity and cariogenic bacteria counts of Mutans streptococci and Lactobacillus spp and to evaluate their relationship with drug therapy, disease activity and duration. METHODS: A cross-sectional study was performed with UC patients followed in a tertiary center. Participants were submitted to a questionnaire (including demographic data, oral hygiene, eating habits) and a clinical observation with assessment of plaque index and Decayed, Missing and Filled Teeth index. Unstimulated/stimulated saliva was collected. Medical records, disease activity (Partial Mayo Score) and disease duration were collected. Laboratory data included salivary flow rates, salivary buffering capacity (CRT® buffer) and cariogenic bacteria count (Mutans streptococci and Lactobacillus spp) in saliva using the CRT® bacteria test (results: high or low counts). RESULTS: Thirty UC patients were recruited. Oral hygiene routines were daily teeth brushing once or more (96.7%) and fluoride toothpaste (73.3%). Decayed, Missing and Filled Teeth index (mean 16.17±6.428) was not affected by the frequency of soft drinks, cakes, sweets and sugars between meals (P>0.2). Long-term disease showed a trend towards higher prevalence of caries (P=0.06). Most presented normal salivary flow rates, unstimulated (73.3%) and stimulated (60.0%), and high salivary buffering capacity (66.7%). Any association was found with age, gender, disease activity, disease duration and drug therapy. High Mutans streptococci and low Lactobacillus spp count were observed in 73.3% and 60% of patients, respectively. Patients with active disease (100%) and longer duration (88.9%) displayed higher Mutans streptococci count. CONCLUSION: The prevalence of dental caries observed in UC patients was significant and did not seem to be influenced by their eating habits. The high prevalence of Mutans streptococci count may be a major risk factor for dental caries and may be looked as part of the UC dysbiosis. Dental care of UC patients should be planned according with this microbiota variation.

RESUMO CONTEXTO: Uma elevada prevalência de cáries dentárias em doentes com retocolite ulcerativa (RCU) tem sido atribuída à dieta e alterações no ambiente salivar. OBJETIVO: Este estudo pretende caracterizar a prevalência de cáries dentárias, taxas de fluxo salivar, capacidade de tamponamento da saliva e contagem de bactérias cariogénicas, Streptococcus mutans e Lactobacillus spp e avaliar a sua relação com a terapêutica farmacológica e a atividade e duração da doença. MÉTODOS: Estudo transversal com doentes com RCU seguidos num centro terciário. Os participantes foram submetidos a um questionário (incluindo questões sobre dados sociodemográficos, higiene oral e hábitos alimentares), e a uma observação clínica com avaliação do índice de placa e índice Decayed, Missing and Filled Teeth. Amostras de saliva não estimulada e estimulada foram colhidas. Os registos clínicos, a atividade da doença (score parcial de Mayo) e a sua duração foram avaliados. Os dados laboratoriais incluíram taxas de fluxo salivar, capacidade de tamponamento da saliva (CRT® buffer) e a contagem de bactérias cariogénicas (Streptococcus mutans e Lactobacillus spp) utilizando o teste CRT® (resultado: contagem elevada ou reduzida). RESULTADOS: Foram recrutados 30 doentes com RCU. As rotinas de higiene oral incluíram a escovagem dos dentes uma ou mais vezes por dia (96,7%) e o uso de pasta com flúor (73,3%). O índice Decayed, Missing and Filled Teeth (média 16,17±6,428) não foi afetado pela frequência de ingestão de refrigerantes, bolos, doces e açucares entre as refeições (P>0,2). Doentes com doença de longa duração apresentaram uma tendência para maior prevalência de cáries dentárias (P=0,06). A maioria possuía taxas de fluxo salivar normais, quer de saliva estimulada (60%) quer de saliva não estimulada (73,3%), assim como taxas de tamponamento salivar elevadas (66,7%). Não foi encontrada associação entre estas características com a idade, género, atividade/duração da doença e tipo de terapêutica farmacológica. Contagens elevadas de Streptococcus mutans e reduzidas de Lactobacillus spp foram observadas em 73,3% e 60% dos doentes, respectivamente. Doentes com doença ativa e maior tempo de evolução apresentaram contagens superiores de Streptococcus mutans. CONCLUSÃO: A prevalência de cárie dentária observada em doentes com RCU foi significativa e não parece ser influenciada pelos hábitos alimentares. A prevalência aumentada de Streptococcus mutans foi o fator de risco maior para a cárie dentária e provavelmente constitui parte da conhecida disbiose oral associada à RCU. Os cuidados dentários a estes doentes deverão ter em consideração esta variação da microbiota.

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.

A case study of ileal metaplasia and neoplasia in a patient with an ileal-rectal anatomosis / Um caso de estudo de metaplasia ileal e neoplasia em paciente com anastomose ileal-retal

ABSTRACT A clear link between ulcerative colitis and the formation of dysplasia and neoplasia has been described. This increased risk remains even after subtotal colectomy and ileo-rectal anastomosis, necessitating life-long surveillance of the remaining ano-rectum. This case study highlights the importance in long-term follow up in this population, including proximal to the anastomosis as dysplastic changes can occur in the distal ileum.

RESUMO Uma ligação clara entre colite ulcerativa e a formação de displasia e neoplasia tem sido descrita. Ese risco aumentado permanece mesmo após colectomia subtotal e ileo-retal, necesitando de uma vigilância ao longo da vida do ano-recto restante. Este caso de estudo realça a importância no acompanhamento a longo prado dessa população, incluindo áqueles próximos à anastomose já que podem ocorrer alteraçoes displásicas no íleo distal.

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.

Eficacia y seguridad de golimumab en pacientes con colitis ulcerativa moderada a severa, refractaria a tratamiento convencional y biológico con infliximab / Efficacy and safety of golimumab in patients with moderate to severe ulcerative colitis, refractory to conventional and biological treatment with infliximab

INTRODUCCIÓN: Antecedentes: El presente dictamen expone la evaluación de tecnologia de la eficacia y seguridad de golimumab en pacientes con colitis ulcerativa moderada o severa, refractaria al tratamiento convencional y biológico con infliximab. Aspectos Generales: La colitis ulcerativa (CU) es la condición crónica más común de las enfermedades gastrointestinales. Frecuentemente se desarrolla entre los 15 y 25 años y 55 y 65 años, aunque no excluye a la población fuera de estos rangos de edad. Esta enfermedad genera inflamación a nivel de la mucosa del colon, siendo variable la extensioón de la inflamación y pudiendo llegar a afectar también el área del recto. Se caracteriza por fases de relapso y remissión. Tecnologia Sanitaria de Interés: Golimumab es un anticuerpo monoclonal humano, inhibidor del factor de necrosis tumoral (TNF-alfa), también llamado anti-TNF. Golimumab es un anti-inflamatorio, el cual bloquea la senãl producida por el TNF-alfa reduciendo así los síntomas de la enfermedad inflamatoria de la colitis ulcerativa. Según la EMA y la FDA, este producto farmacéutico puede ser utilizado para el tratamiento de pacientes con el diagnóstico de colitis ulcerosa a grave, en adultos que no han respondido adecuadamente a un tratamiento convencional o que no pueden recibirlo. METODOLOGIA: Estrategia de Búsqueda: Se utilizó el motor de búsqueda Pubmed empleando el algoritmo mostrado en la subsección B y los filtros correspondientes a meta-análisis, revisiones sistemáticas y ensayos clínicos, en línea con los criterios de elegibilidad. Se llevó a cabo una búsqueda sistemática de la literatura con respecto a la eficacia y seguridad de golimumab en pacietnes con colitis ulcerativa moderada o severa, refractaria al tratamiento convencional y biológico con infliximab. Para la búsqueda primaria se revisó, en primer lugar, la información dispoible por entes reguladoras y normativas de autorización comercial como la Administración de Drogas y Alimentos (FDA) de Estados Unidos, la Agencia de Medicamentos Europea (EMA) y la Dirección General de Medicamentos y Drogas (DIGEMID) en el Perú. RESULTADOS: Se llevó a cabo una búsqueda de evidencia científica relacionada al uso de golimumab en pacientes con colitis ulcerativa moderada o severa refractaria al tratamiento convencional y al tratamiento biológico con infliximab. Se han encontrado revisiones narrativas, en cuyas referencias se extrajeron estudios obervacionales como series de casos, sin embargo,e stos estudios sugieren otros anti-TNFs como respuesta a este tipo de pacientes, más no golimumab. Por lo tanto, la evidecia presentada a continuación constituye evidencia indirecta, que es la única referenciada por las GPC más actualies para el manejo de CU. CONCLUSIONES: La presente evaluación de tecnología sanitaria expone la evidencia científica encontrada a la fecha (enero 2016) acerca de la eficacia y seguridad de golimumab en pacientes con colitis ulcerativa moderada o sevra, refractaria al tratamiento convencional y biológico con infliximab. Se han encontrado series de casos que sugieren el uso de otros anti-TNFs como respuesta tras fallar al tratamiento con infliximab, más no golimumab. El Instituto de Evaluación de Tecnologías en Salud e Investigación-IETSI no aprueba el uso de golimumab en pacientes con colitis ulcerativa moderada o severa, refractaria al tratamiento convencional y biológico con infliximab.

Alert for bone alterations and low serum concentrations of vitamin D in patients with intestinal inflammatory disease / Alerta para alterações ósseas e baixas concentrações séricas de vitamina D em pacientes com doença inflamatória intestinal

Summary Background: Inflammatory bowel diseases (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), are characterized by chronic inflammation of the intestine that can reduce the absorption of nutrients such as vitamin D and calcium. Objective: To investigate bone alterations and serum levels of vitamin D in patients with IBD. Method: This was a cross-sectional study based on a review of medical records of patients from a private office in Curitiba, PR, Brazil. Serum levels of vitamin D and bone densitometry were measured at diagnosis of IBD. A total of 105 patients were included; 38 (58.4%) with CD; 27 (41.6%) with UC and 40 with irritable bowel syndrome (IBS) as comparison group. Results: When compared to patients with UC, CD patients showed a higher prevalence of bone alterations, being 15.8% with osteoporosis and 36.8% with osteopenia. In UC, bone alterations occurred in 29.6% of cases, 3.7% with osteoporosis and 25.9% with osteopenia. As for vitamin D levels, among CD patients, 10.5% had vitamin deficiency, 65.8% insufficiency and 23.7% were sufficient. In UC, 7.4% of cases had deficiency, 74.1% insufficiency and 18.5% had sufficient serum levels of vitamin D. In the group with IBS, deficiency was observed in 17.5% of cases, insufficiency in 55% and sufficiency in 27.5% of them. There was no significant difference between groups. Conclusion: IBD patients have a high prevalence of bone changes, especially those with CD. Serum levels of vitamin D are below the recommended in all the evaluated groups.

Resumo Introdução: A doença inflamatória intestinal (DII), como a doença de Crohn (DC) e a retocolite ulcerativa (RU), caracterizam-se pela inflamação crônica no intestino, que pode reduzir a absorção de vitamina D e cálcio. Objetivo: Investigar as alterações ósseas presentes em pacientes com DII e as dosagens séricas de vitamina D. Método: Estudo transversal analítico baseado na revisão de prontuários de pacientes com DII de um consultório privado de Curitiba, PR. Em todos os pacientes, foram dosadas as concentrações séricas de vitamina D e foi feita a densitometria óssea. Cento e cinco pacientes foram incluídos no estudo, dos quais 38 (58,4%) foram diagnosticados com DC, 27 (41.6%) com RU e 40 com síndrome do intestino irritável (SII) como grupo de comparação. Resultados: Quando comparados com pacientes com RU, os pacientes com DC apresentaram maior prevalência de alterações ósseas, sendo 15,8% com osteoporose e 36,8% com osteopenia. Na RU, as alterações ósseas ocorreram em 29,6% dos casos, 3,7% com osteoporose e 25,9% com osteopenia. Em relação às dosagens de vitamina D, dentre os pacientes com DC, 10,5% apresentavam deficiência, 65,8%, insuficiência e 23,7%, suficiência. Na RU, 7,4% dos casos tinham deficiência, 74,1%, insuficiência e 18,5%, suficiência. No grupo com SII, observaram-se deficiência em 17,5%, insuficiência em 55% e suficiência em 27,5%. Não foi observada diferença significativa entre os grupos. Conclusão: Pacientes com DII apresentaram alta prevalência de alterações ósseas, principalmente aqueles com DC. As concentrações séricas de vitamina D estão abaixo do recomendado em todos os grupos avaliados.

Bone mineral density and inflammatory bowel disease severity

Inflammatory bowel disease (IBD) is associated with low bone mineral density (BMD). In this study, the association between disease severity and BMD in patients with IBD was evaluated. Associations between BMD and the Montreal classification, disease activity and drug therapy were also tested. A cross-sectional prevalence study with a comparison group was conducted. One hundred and twenty-eight patients were evaluated: 68 patients with ulcerative colitis (UC), and 60 with Crohn's disease (CD). The control group consisted of 67 healthy subjects. All patients and controls had BMD measured and in IBD patients, current medications, hospitalization, and disease location, extent and phenotype, according to the Montreal classification, were recorded. Multiple correspondence analysis was applied to evaluate categorical variables. In the CD group, most patients were diagnosed between 17-40 years of age. Ileocolonic and non-stricturing non-penetrating disease were the most frequent disease location and behavior, respectively. In UC patients, extensive colitis was the most frequent disease location. UC and CD patients were more likely to have osteopenia than controls (OR=14.93/OR=24.38, respectively). In the CD group, male patients, perianal disease, penetrating behavior and age at diagnosis >40 years were associated with low BMD. Taking azathioprine and infliximab also seemed to be associated with osteopenia. In the UC group, we observed an association between low BMD and male patients, left colitis, corticosteroid use and hospitalization. Disease activity was not associated with osteopenia or osteoporosis in CD and UC patients. Disease severity seems to be associated with osteopenia in IBD patients.

Calidad del sueño en pacientes con enfermedad inflamatoria intestinal / Sleep quality in inflammatory bowel disease patients

Although inflammatory bowel disease (IBD) etiology is still unknown, genetic, environmental and immunological factors are implicated. Studies have considered quality of sleep as a risk factor in IBD course. Objective: To determine sleep quality in IBD patients, irritable bowel syndrome (IBS) patients and healthy controls (HC). Methods: Cross sectional study assessing sleep quality in adult patients with IBD, IBS and HC. All patients answered a validated Spanish version of the Pittsburgh Sleep Quality Index (PSQI) questionnaire in order to evaluate sleep quality. A PSQI global score > 5 is indicative of poor sleep quality. Demographic and clinical variables were assessed. Results: The study included 276 patients, 111 with IBD, 85 with IBS and 80 HC. A PSQI score > 5 was observed in 67 percent of IBD and IBS patients and 55 percent of HC. IBD and IBS patients exhibited poorer sleep quality than HC, although results did not reach statistical significance (p = 0.069 and p = 0.076, respectively). In IBD patients, an association between disease activity and sleep quality was observed (p = 0.025). However, when analyzing separately patients with ulcerative colitis (UC) and Crohn ́s Disease (CD), only in UC patients sleep quality was related with disease activity. The use of sleep medications was significantly higher in IBD and IBS patients compared with healthy controls (p = 0.021 and p = 0.009, respectively). Conclusion: Sleep disturbances are frequent in IBD, IBS patients and even healthy controls. Additionally, IBD patients with active disease, particularly those with UC, exhibit worse sleep quality.

Aunque la etiología de la enfermedad inflamatoria intestinal (EII) es aún desconocida, factores genéticos, ambientales e inmunológicos estarían implicados. Estudios han considerado la calidad del sueño como un factor de riesgo en la evolución de la EII. Objetivo: Determinar la calidad del sueño en pacientes con enfermedad inflamatoria intestinal (EII), síndrome intestino irritable (SII) y controles sanos (CS). Métodos:Estudio transversal en pacientes adultos con EII, SII y CS. Se evaluó la calidad del sueño mediante el Índice de Calidad del Sueño de Pittsburgh (ICSP), siendo una puntuación global > 5 indicativa de mala calidad del sueño. Variables demográficas y clínicas fueron evaluadas. Resultados:Se incluyeron 276 pacientes, 111 con EII, 85 SII y 80 CS. ICSP > 5 fue observado en 67 por ciento de los pacientes con EII y SII, y 55 por ciento de los CS. Los pacientes con EII y SII mostraron una peor calidad del sueño comparado con CS sin alcanzar significancia estadística (p: 0,069 y p: 0,076, respectivamente). En los pacientes con EII, se observó una asociación entre actividad de la enfermedad y calidad del sueño (p: 0,025). Sin embargo, al analizar por diagnóstico específico, sólo pacientes con colitis ulcerosa (CU) presentaron esta asociación. El uso de medicamentos para dormir fue significativamente mayor en los pacientes con EII y SII comparado con CS (p: 0,021 y p: 0,009, respectivamente). Conclusión:Los trastornos del sueño son frecuentes en pacientes con EII, SII e incluso CS. Pacientes con EII activa, en particular aquellos con CU, presentaron una peor calidad del sueño.

LOWER LEVELS OF VITAMIN D CORRELATE WITH CLINICAL DISEASE ACTIVITY AND QUALITY OF LIFE IN INFLAMMATORY BOWEL DISEASE

Background - Inflammatory bowel disease, comprising Crohn's disease and ulcerative colitis, is a group of debilitating conditions associated with deregulated mucosal immune response. Vitamin D has been implicated in immune response and gastrointestinal function. Objectives - To investigate the correlation between serum vitamin D levels and disease activity and quality of life in patients with inflammatory bowel disease. Methods - This cross-sectional study enrolled ambulatory patients with inflammatory bowel disease and assessed clinical disease activity and quality of life (Short Inflammatory Bowel Disease Questionnaire [SIBDQ]). Vitamin D levels were determined via serum 25-hydroxyvitamin D measurement; deficiency was defined as values <20 ng/mL. Statistical analysis was performed with SPSS vs 20.0. Results - A total of 76 patients were enrolled, 19 with ulcerative colitis (25%) and 57 with Crohn's disease (75%). Overall, mean serum 25-hydroxyvitamin D levels were low (26.0±10.0 ng/mL), while those in patients with Crohn's disease were significantly lower than ulcerative colitis (24.6±8.0 vs 30.0±12.5 ng/mL; P=0.032). Vitamin D deficiency was found in 30% of patients. Patients who were in clinical remission were found to have higher levels of vitamin D than those who were not in remission (28.0±10.3 vs 21.6±6.0 ng/mL, P=0.001). Inflammatory bowel disease patients with SIBDQ scores <50 were found to have significantly lower mean vitamin D levels compared with patients who had SIBDQ scores ≥50 (23.4±6.9 vs 27.9±10.8 ng/mL, P=0.041). Conclusions - A high proportion of patients with inflammatory bowel disease were vitamin D deficient, particularly patients with Crohn's disease. Both clinical disease activity and quality of life correlated significantly with lower levels of vitamin D, illustrating a clear need for supplementation in patients with inflammatory bowel disease.

Contexto - A doença inflamatória intestinal, que compreende a doença de Crohn e a colite ulcerosa, é um grupo de entidades incapacitantes associada a uma resposta imunitária desregulada. A vitamina D tem sido associada à resposta imune e funções gastrointestinais. Objetivo - Investigar a correlação entre os níveis séricos de vitamina D, a atividade clínica da doença e a qualidade de vida em doentes com doença inflamatória intestinal. Método - Estudo transversal que incluiu doentes em ambulatório com doença inflamatória intestinal avaliando a atividade clínica da doença e a qualidade de vida (Short Inflammatory Bowel Disease Questionnaire [SIBDQ]). Os níveis séricos de vitamina D foram determinados através dos níveis de 25-hidroxivitamina D; a deficiência de vitamina D foi definida para valores <20 ng/mL. Resultados - Foram incluídos 76 doentes, 19 com colite ulcerosa (25%) e 57 com doença de Crohn (75%). No global, os valores séricos médios de 25-hidroxivitamina D foram baixos (26,0±10,0 ng/mL), os doentes com doença de Crohn apresentaram níveis mais baixos do que os doentes com colite ulcerosa (24,6±8,0 vs 30,0±12,5 ng/mL; P=0,032). O défice de vitamina D foi identificado em 30% dos doentes. Os doentes em remissão clínica apresentaram níveis mais elevados de vitamina D (28,0±10,3 vs 21,6±6,0 ng/mL, P=0,001). Doentes com SIBDQ <50 apresentaram níveis significativamente inferiores de vitamina D em comparação com doentes com SIBDQ ≥50 (23,4±6,9 vs 27,9±10,8 ng/mL, P=0,041). Conclusão - Uma percentagem elevada de doentes apresentou deficiência de vitamina D, em particular doentes com doença de Crohn. A atividade clínica e a qualidade de vida dos doentes com doença inflamatória intestinal correlacionou-se com níveis mais baixos de vitamina D, ilustrando uma clara necessidade de suplementação desta vitamina em doentes com doença inflamatória intestinal.
