ABSTRACT

ABSTRACT BACKGROUND: A healthy diet is recommended for patients with Crohn's disease (CD) in remission. OBJECTIVE: To evaluate the diet quality of patients with CD. METHODS: Cross-sectional study with patients with CD and clinical remission using the biological agent infliximab. The diet quality was assessed using the Diet Quality Index-Revised (DQI-R). DQI-R was calculated based on 24-hour dietary recalls (24HR), being classified as "inadequate diet" (≤40 points), "diet requiring modifications" (41 to 64 points) and "healthy diet" (≥65 points). Weight, height and waist circumference (WC) of patients were assessed. For comparison between groups, Student's t-test or Mann-Whitney was used. For correlation between continuous variables, Pearson or Spearman coefficient was used. Values of P<0.05 indicated statistical significance. RESULTS: A total of 43 patients participated in the study. The final DQI-R score was 49.1 points - "diet requiring modifications". No patient received the classification of "healthy diet" (maximum score =59.7), 55.8% presented "diet requiring modifications" and 44.2% "inadequate diet". When comparing the "inadequate diet" and "diet requiring modifications" groups, a lower mean age was observed in the "inadequate diet" group (37.6±14.8 versus 47.4±10.5 y, P=0.02). It was found that 44.2% of the patients were overweight (body mass index [BMI] ≥25 kg/m²) and had increased WC (women: WC ≥80 cm and men: WC ≥94 cm). A positive correlation was found between the final DQI-R score and BMI (P=0.046; r=0.346). CONCLUSION: Patients with CD in clinical remission using infliximab are not adopting a diet considered healthy, which points to the need for an individualized nutritional approach.


RESUMO CONTEXTO: É recomendado alimentação saudável para pacientes com doença de Crohn (DC) em remissão. OBJETIVO: Avaliar a qualidade da dieta de pacientes com DC. MÉTODOS: Estudo transversal com pacientes com DC em remissão clínica e em uso do imunobiológico infliximabe. A qualidade da dieta foi avaliada pelo índice de qualidade da dieta revisado (IQD-R). O IQD-R foi calculado a partir do recordatório 24 horas, sendo classificado em "dieta inadequada" (≤40 pontos), "dieta que requer modificações" (41 a 64 pontos) e "dieta saudável" (≥65 pontos). Os pacientes foram avaliados quanto ao peso, altura e circunferência da cintura (CC). Para comparação entre grupos foi utilizado o test-t de Student ou Mann-Whitney. Para correlação entre variáveis contínuas foi utilizado o coeficiente de Pearson ou Spearman. Valores de P<0,05 indicaram significância estatística. RESULTADOS: Participaram do estudo 43 pacientes. A pontuação final do IQD-R foi de 49,1 pontos - "dieta que requer modificações". Nenhum paciente recebeu a classificação de "dieta saudável" (pontuação máxima =59,7), 55,8% apresentaram "dieta que requer modificações" e 44,2% "dieta inadequada". Ao comparar os grupos "dieta inadequada" e "dieta que requer modificações", foi observado menor média de idade no grupo "dieta inadequada" (37,6±14,8 versus 47,4±10,5 anos, P=0,02). Verificou-se que 44,2% dos pacientes estavam acima do peso (índice de massa corporal (IMC) ≥25 kg/m²) e possuíam CC aumentada (mulheres: CC ≥80 cm e homens: CC ≥94 cm). Foi encontrada correlação positiva entre a pontuação final do IQD-R e o IMC (P=0,046; r=0,346). CONCLUSÃO: Os pacientes com DC em remissão clínica e em uso de infliximabe não estão adotando dieta com qualidade considerada saudável o que aponta a necessidade de abordagem nutricional individualizada.

ABSTRACT

ABSTRACT BACKGROUND: The rates of postoperative endoscopic recurrence (PER) in patients with Crohn's disease (CD) are consistent. Anti-TNF therapy has been increasingly used in the postoperative setting, despite the lack of robust data in the literature on the measurement of trough levels and consequences of their use. OBJECTIVE: The aim of this review was to assess trough levels of infliximab (IFX) in CD patients after ileocolonic resections in correlation with the presence of PER. METHODS: We searched for studies that evaluated trough levels of IFX in patients with CD, who underwent ileocaecal resections, and correlated them with the presence of PER. We used MEDLINE through PubMed and CENTRAL Cochrane library databases, and after matching the inclusion criteria, the studies were methodologically evaluated with qualitative analysis of the data. RESULTS: A total of 155 studies were initially identified in the databases search and only four matched the inclusion criteria. They comprised one prospective cohort study, one randomized controlled trial and two retrospective cohort studies, the last one performed in pediatric patients. This evidence suggested the correlation of PER with low trough levels of IFX and the presence of antibodies to the drug. The quality of the evidence generated varied from very low to high, due to the heterogeneity found between the studies and the risks of bias that were identified. CONCLUSION: Low levels of IFX and the presence of antibodies to the drug were directly associated with increased PER rates in patients with CD, who underwent ileocolonic resections. Controlled and randomized clinical trials with adequate methodological quality are warranted to confirm the conclusions from this systematic review.


RESUMO CONTEXTO: As taxas de recorrência endoscópica pós-operatória em pacientes com doença de Crohn (DC) são significativas. A terapia anti-TNF é cada vez mais usada no cenário pós-operatório, apesar da escassez de dados na literatura sobre dosagem de níveis séricos e anticorpos da droga. OBJETIVO: Realizou-se uma revisão sistemática com o intuito de se avaliar níveis séricos de infliximabe (IFX) em pacientes com DC submetidos a ileocolectomia e correlacionar com a presença ou não de recorrência endoscópica da doença. MÉTODOS: Buscou-se por estudos que avaliaram o nível sérico do IFX em pacientes com DC, submetidos a ileocolectomias, correlacionando-os à presença de recorrência endoscópica pós-operatória. Utilizou-se as bases de dados MEDLINE via PubMed e CENTRAL Cochrane Library, e após atingirem os critérios de inclusão, os estudos foram avaliados metodologicamente e foi realizada análise qualitativa dos dados. RESULTADOS: Um total de 155 estudos foram identificados e apenas quatro atingiram os critérios de inclusão. Um era estudo de coorte prospectivo, o segundo era um ensaio clínico randomizado e dois eram estudos de coortes retrospectivas, sendo o último exclusivamente em pacientes pediátricos. As evidências encontradas tendem a confirmar a correlação da recorrência endoscópica a baixos níveis séricos de IFX e presença de anticorpos anti-droga. A qualidade da evidência gerada variou de muito baixa a alta, devido à heterogeneidade encontrada entre os estudos e o risco de viés identificado. CONCLUSÃO: Baixos níveis séricos do IFX e presença de anticorpos contra a droga estão associados a probabilidade aumentada de recorrência endoscópica pós-operatória nos pacientes com DC submetidos a ileocolectomias. Ensaios clínicos controlados e randomizados com adequada qualidade metodológica são necessários para confirmar as conclusões desta revisão.

ABSTRACT

Abstract As the treatment of infectious and parasitic diseases improved, the prevalence of these conditions declined. However, with the expansion of the use of immunobiologicals, opportunistic infections have emerged, especially under atypical presentations. The present study reports the case of a patient treated with infliximab for Crohn's disease, who presented diarrhea, weight loss, abdominal pain, fever, and subcutaneous erythematous nodules that evolved with spontaneous fluctuation and ulceration. With the finding of alcohol-resistant bacilli and Mycobacterium tuberculosis DNA in a cutaneous fragment, through polymerase chain reaction, the diagnosis of gummatous tuberculosis was confirmed, probably secondary to hematogenous dissemination from an intestinal focus.

ABSTRACT

OBJECTIVES@#At present, there are many studies on Crohn's disease of terminal ileum and colon, but few studies on Crohn's disease of small intestine alone. This study aims to analyze the clinical features and therapeutic effect of small bowel in adult patients with Crohn's disease so as to strengthen the diagnosis and treatment for this disease.@*METHODS@#From July 1, 2015 to October 31, 2018, patients with small bowel Crohn's disease at Department of Gastroenterology, Third Xiangya Hospital of Central South University, were enrolled. At the same time, patients' demographics and clinical data were collected.@*RESULTS@#A total of 44 patients were small bowel Crohn's disease. Among them, 40 patients were male. The age at diagnosis was (35.8±10.3) years old and disease duration was (35.2±59.5) months. The subtypes included 29(65.9%) of ileum, 7(15.9%) of jejunum, 8(18.2%) of ileum with jejunum. There were 27(61.4%) of stricture behavior, 4(9.1%) of penetrating behavior, and 13(29.5%) of non-stricture and non-penetrating behavior. Endoscopic visible stricture (29/85, 34.1%) was common, followed by longitudinal ulcers (27/85, 31.8%). Non-caseate granulomatous were found in 2 cases (4.5%). The score of Crohn's disease activity index was correlated to hemoglobin, hematocrit, and erythrocyte sedimentation rate (all @*CONCLUSIONS@#Patients with ileum account for a large proportion in patients with small bowel Crohn's disease. Stricture is more common in small bowel Crohn's disease. Stricture and longitudinal ulcer are more common under enteroscopy. Crohn's disease activity index is correlated to hemoglobin, red blood cell specific volume, and erythrocyte sedimentation rate. The most common complication is intestinal obstruction. Mesalazine is less effective on small bowel Crohn's disease.

ABSTRACT

SUMMARY AIM: To compare the level of physical activity (PA), exercise capacity, and body composition before and after infliximab-induced clinical remission in patients with Crohn's disease (CD). METHODS: This prospective longitudinal study evaluated 44 adult outpatients with active CD before infliximab administration and 24 weeks after infliximab therapy. The patients were evaluated for PA in daily life, exercise capacity, muscle strength, and body composition. RESULTS: 38 (86.4%) patients achieved infliximab-induced remission at 24 weeks and presented an increment in the number of steps taken of 1092 (7440±2980 vs. 6348±3177, respectively; p=0.006). The inactive time was reduced when compared to the baseline value (454.2±106.3 vs. 427.9±97.8, respectively; p=0.033). There was no difference in the distance walked before and after infliximab therapy, while there was an increase in the fat mass index in responders to infliximab compared to the baseline (19.1±7.6 vs. 14.9±5.8; p=0.001). CONCLUSIONS: Infliximab-induced remission was shown to be effective for increasing physical activity by improving the number of steps and reducing inactive time. The maintenance of clinical remission associated with incentives to regular PA may contribute to making these patients reach an ideal level of PA.


RESUMO OBJETIVO: Comparar o nível de atividade física (AF), capacidade de exercício e composição corporal antes e após remissão clínica induzida por infliximabe em pacientes com doença de Crohn (DC). MÉTODOS: Neste estudo longitudinal prospectivo, foram envolvidos 44 pacientes ambulatoriais adultos com DC ativa avaliados antes e depois de 24 semanas de terapia com infliximabe. Os pacientes foram avaliados quanto à AF, capacidade de exercício, força muscular e composição corporal. RESULTADOS: 38(86,4%) pacientes alcançaram remissão induzida por infliximabe em 24 semanas e apresentaram aumento no número de passos de 1092 (7440±2980 vs. 6348±3177, respectivamente; p=0,006). O tempo de inatividade foi reduzido quando comparado ao basal (454,2±106,3 vs. 427,9±97,8, respectivamente; p=0,033). Não houve diferença na distância percorrida antes e após a terapia com infliximabe, enquanto houve aumento no índice de massa gorda nos respondedores ao infliximabe em comparação ao basal (19,1±7,6 vs. 14,9±5,8; p=0,001). CONCLUSÕES: A remissão induzida pelo infliximabe mostrou-se eficaz no aumento da atividade física, melhorando o número de passos e reduzindo o tempo inativo. A manutenção da remissão clínica associada a incentivos à AF regular pode contribuir para que esses pacientes atinjam um nível ideal de AF.

ABSTRACT

ABSTRACT BACKGROUND: Patients with inflammatory bowel disease (IBD) vaccinated for hepatitis B have a low success rate in achieving protective antibody levels. The main factors suggested for this are IBD itself and the use of immunosuppressive drugs. OBJECTIVE: To evaluate the concentration of anti-HBs antibodies and to verify factors associated with the effectiveness of hepatitis B vaccination in patients with IBD. METHODS: This is a prospective, consecutive, observational, descriptive and analytical, non-randomized, qualitative study that evaluated the levels of anti-HBs antibodies in IBD patients at the Interdisciplinary Inflammatory Bowel Disease Clinic of the Family and Community Health Unit of UNIVALI - Itajaí, Santa Catarina. RESULTS: Thirty-six patients were vaccinated against hepatitis B virus (HBV), of which 29 were female. The average age was 46.2 years. Regarding the type of IBD, twenty-four patients had Crohn's disease and the duration of inflammatory bowel disease was 74 months. Fifteen patients were on concomitant immunosuppressive therapy. The effective response rate to HBV vaccine was 72.2%, verified by anti-HBs titration ≥10 UI/L. Statistical analysis revealed a negative response to vaccination in patients with Crohn's disease and immunosuppressive drugs. CONCLUSION: The success rate of HBV immunization in IBD patients is low compared to the general population. Type of disease and use of immunosuppressive drugs appear to influence the vaccine response.


RESUMO CONTEXTO: Os pacientes com doenças inflamatórias intestinais (DII) vacinados para hepatite B possuem baixa taxa de sucesso em alcançar níveis protetores de anticorpos. Os principais fatores sugeridos para isso são a própria DII e o uso de medicamentos imunossupressores. OBJETIVO: Avaliar a titulação de anticorpos anti-HBs e verificar fatores associados a efetividade da vacinação contra hepatite B em pacientes com DII. MÉTODOS: Trata-se de um estudo prospectivo e consecutivo, de caráter observacional, descritivo e analítico, não-randomizado, qualiquantitativo, que avaliou a titulação de anticorpos anti-HBs em pacientes portadores de DII no Ambulatório Interdisciplinar de Doença Inflamatória Intestinal da Unidade de Saúde da Família e Comunitária da UNIVALI - Itajaí, Santa Catarina. RESULTADOS: Trinta e seis pacientes foram vacinados contra o vírus da hepatite B (VHB), destes, 29 eram do sexo feminino. A média de idade foi de 46,2 anos. Em relação ao tipo de DII, 24 pacientes eram portadores de doença de Crohn e o tempo médio de doença inflamatória intestinal encontrado foi de 74 meses. Quinze pacientes estavam em uso de terapia imunossupressora concomitante à vacinação. A taxa de resposta à vacina contra o VHB foi de 72,2%, verificada através de titulação de anti-HBs ≥10 UI/L. A análise estatística revelou uma resposta negativa à vacinação em pacientes em uso de medicamentos imunossupressores e portadores de doença de Crohn. CONCLUSÃO: A taxa de sucesso na imunização contra o VHB em pacientes com DII é baixo quando comparado à população em geral. Tipo de doença e uso de medicamentos imunossupressores parecem desempenhar influência na resposta vacinal.

ABSTRACT

ABSTRACT Inflammatory bowel disease comprises two distinct conditions - Crohn's disease and ulcerative colitis - which can be treated with immunomodulators. A non-neglectable proportion of these patients will need biologic therapy, and many patients under biologic treatment will experience either primary or secondary failure. As a consequence, clinical trials evaluating new therapeutic alternatives are being developed. These trials share common features, such as being controlled with placebo. Placebo use in clinical trials is a matter of intense debate. Those who support placebo use highlight the methodologic advantages placebo-controlled trials have. Those against placebo use argue that it would be against ethical principles in clinical research to expose a patient to placebo when a valid therapeutic alternative exists. In this review, we summarize the existing arguments for and against the use of placebo in the context of inflammatory bowel disease research. We finally suggest that it is very likely that in the near future inflammatory bowel disease trials will no longer be controlled with a placebo arm, but instead they will be non-inferiority trials with an active comparator.


RESUMO A doença inflamatória intestinal compreende duas condições distintas: a doença de Crohn e a retocolite ulcerativa, que podem ser tratadas com imunomoduladores. Uma proporção não negligenciável desses pacientes necessitará de terapia biológica e, muitos destes em tratamento biológico, experimentarão falha primária ou secundária. Como consequência, ensaios clínicos avaliando novas alternativas terapêuticas estão sendo desenvolvidos. Estes ensaios partilham características comuns, tais como ser controlado com placebo. O uso de placebo em ensaios clínicos é uma questão de intenso debate. Aqueles que apoiam o uso do placebo destacam as vantagens metodológicas que os ensaios controlados com placebo têm. Aqueles contra o uso de placebo argumentam que seria contra os princípios éticos na investigação clínica expor um paciente ao placebo quando uma alternativa terapêutica válida existe. Nesta revisão, resumimos os argumentos existentes a favor e contra o uso de placebo no contexto da pesquisa de doença inflamatória intestinal. Finalmente, sugerimos que é muito provável que em um futuro próximo os ensaios de doença inflamatória intestinal não serão mais controlados com um braço placebo; em vez disso, serão feitos ensaios de não-inferioridade com um comparador ativo.

ABSTRACT

ABSTRACT Background: Anti-TNF drugs are a fundamental part of the treatment of Crohn's disease (CD), so identifying factors related to loss of response is of great importance in clinical practice. Aim: Identify potential factors related to loss of response to anti-TNF agents in Crohn's disease patients. Methods: This is a prospective study of CD patients attending a specialized outpatient clinic using a specific form, including patients with more than one year of follow-up on anti-TNF (Infliximab, Adalimumab or Certolizumab pegol). The information obtained was tabulated and analyzed to identify possible reasons for the loss of response to anti-TNF agents; results were submitted to statistical analysis by chi-square teste considering significant p<0.05. Results: Sixty-four patients were included, most of them females (56.3%), predominant age group between 26 and 55 years, of whom 25 required optimization, 23 remained in remission with the usual dose and interval, and 16 required switch; most of those who needed switch had hematological problems such as anemia and/or had already undergone surgical treatment for CD. Conclusions: Anemia and prior CD surgery have been linked to loss of anti-TNF response.


RESUMO Racional: Os anti-TNF são parte fundamental no tratamento da doença de Crohn (DC), portanto, identificar os fatores relacionados à perda de resposta tem grande importância na prática clínica. Objetivo: Identificar potenciais fatores relacionados a perda de resposta aos agentes anti-TNF em pacientes com DC. Métodos: Trata-se de um estudo prospectivo de pacientes com DC frequentadores de ambulatório especializado por meio de formulário específico, incluindo-se pacientes com mais de um ano de acompanhamento em uso de anti-TNF (Infliximabe, Adalimumabe ou Certolizumabe pegol). As informações obtidas foram tabuladas e analizadas para identificação de eventuais motivos para a perda de resposta aos agentes; os resultados foram submetidos a tratamento estatístico por meio do teste qui-quadrado considerando-se significante p<0,05. Resultados: Foram incluídos 64 pacientes, sendo a maioria do sexo feminino (56,3%), faixa etária predominante entre 26 e 55 anos, dos quais 25 necessitaram otimização, 23 se mantiveram em remissão com a dose e intervalo habituais, e 16 necessitaram troca de medicamento; a maioria dos que necessitaram troca tinham alterações hematológicas como anemia e/ou já haviam sido submetidos a tratamento cirúrgico pela doença. Conclusões: Anemia e operação prévia por DC foram relacionados a perda de resposta aos anti-TNF.

ABSTRACT

ABSTRACT BACKGROUND: Physical activity in daily life and exercise capacity have not been assessed in patients with Crohn's disease to date. OBJECTIVE: To evaluate the physical activity in daily life, exercise capacity, quality of life, and prevalence of mood disorders in patients with moderate-to-severe Crohn's disease on infliximab-induced remission and the possible associations among variables. METHODS: A cross-sectional preliminary study was conducted. Twenty-six patients with Crohn's disease and 20 controls were selected. Participants underwent evaluation of physical activity in daily life (triaxial accelerometer), exercise capacity (shuttle walk test), handgrip strength, quality of life, and presence of mood disorders. RESULTS: The number of steps taken (7446±3081 vs 7898±2487), active time (80.6±42 vs 89.7±24.3min), shuttle walk test distance [665 (405) vs 710 (409) m] and handgrip strength [31 (15) vs 29 (20) kgf did not show any difference between the patients with Crohn's disease and the controls. The time spent lying down [95.8 (68.8) vs 60.9 (74.7) min] was greater and some domains of the quality of life were superior in the patients with Crohn's disease. No correlation was observed between the physical activity in daily life and quality of life or presence of mood disorders in patients with Crohn's disease. CONCLUSION: Patients with Crohn's disease on infliximab-induced remission, despite to more time spent lying down, they have the same level of physical activity in daily life and exercise capacity min compared with the controls.


RESUMO CONTEXTO: A atividade física na vida diária e a capacidade de exercício não tem sido avaliada em pacientes com doença de Crohn. OBJETIVO: Avaliar a atividade física na vida diária, capacidade de exercício, qualidade de vida e distúrbios de humor em pacientes com doença de Crohn moderada-grave em remissão induzida pelo infliximabe, e as possíveis associações entre essas variáveis. MÉTODOS: Este foi um estudo preliminar transversal, envolvendo 26 pacientes com doença de Crohn e 20 controles. Os participantes realizaram as seguintes avaliações: atividade física na vida diária por meio de um acelerômetro triaxial, capacidade de exercício (teste de Shuttle), força de preensão palmar, qualidade de vida e distúrbios do humor. RESULTADOS: O número de passos registrados (7446±3081 vs 7898±2487), o tempo ativo (80,6±42,0 vs 89,7±24,3min), a distância caminhada no teste de Shuttle 665 (405) vs 710 (409) m, e a força de preensão manual 31(15) vs 29 (20) kgf não mostraram diferenças entre os pacientes com doença de Crohn e os controles, respectivamente. O tempo gasto na posição deitada 95.8 (68.8) vs 60.9 (74.7) min, e alguns domínios da qualidade de vida foram maiores nos pacientes com doença de Crohn. Nenhuma correlação foi observada entre a atividade física na vida diária e a qualidade de vida ou distúrbios do humor nos pacientes com doença de Crohn. CONCLUSÃO: Pacientes com doença de Crohn em remissão induzida por infliximabe, apesar de passarem mais tempo deitados, apresentam mesmo nível de atividade física e capacidade de exercício quando comparados aos controles.

ABSTRACT

ABSTRACT BACKGROUND: Non-alcoholic fatty liver disease is characterized by deposition of lipids in the hepatic parenchyma exceeding 5% of liver weight in the absence of other conditions, such as viral or alcoholic hepatitis and metabolic disease. Non-alcoholic fatty liver disease is the most common form of chronic liver disease in several countries. In addition to liver complications, recent studies have shown a relation between liver fat and sarcopenia. OBJECTIVE: Determine the association between sarcopenia and the severity of non-alcoholic hepatic steatosis diagnosed by abdominal ultrasonography. METHODS: A clinical, cross-sectional study was conducted with a sample of male and female adults (18 to 70 years of age) submitted to ultrasonography for the investigation of non-alcoholic hepatic steatosis. Evaluations were also performed for the determination of upper and lower limb muscle strength. Data analysis was performed with the aid of the SPSS 22.0 program and involved ANCOVA and the Bonferroni post hoc test, with P-value <0.05 considered indicative of statistical significance. RESULTS: One hundred two patients were submitted to abdominal ultrasonography, 57.8% of whom presented some degree of non-alcoholic hepatic steatosis. The presence and degree of fatty liver infiltration were significantly associated with the sarcopenic index, determined by the ratio between upper and lower limb strength and BMI (P=0.009 and post-test P=0.028 for upper limbs; P=0.006 and post-test P=0.013 for lower limbs). CONCLUSION: In the present study, an association was found between the sarcopenic index and non-alcoholic hepatic steatosis, with an inversely proportional relation between this index and the severity of fatty infiltration. This finding offers further evidence of the metabolic interaction of the liver, adipose tissue and muscle.


RESUMO CONTEXTO: A doença hepática gordura não-alcoólica caracteriza-se pela deposição de lipídios no parênquima hepático, excedendo 5% do peso do fígado na ausência de outras afecções como hepatites virais, alcoólicas ou doenças metabólicas. A doença hepática gordura não-alcoólica tem sido observada como a forma mais comum de doença hepática crônica em diversos países. Além das complicações hepáticas, estudos recentes têm demonstrado a relação entre a presença de gordura hepática e a sarcopenia. OBJETIVO: Determinar a associação entre a sarcopenia e a gravidade da esteatose hepática não-alcoólica diagnosticada pela ultrassonografia abdominal. MÉTODOS: Estudo clínico e transversal com amostra de pacientes de ambos os sexos, de 18 a 70 anos de idade, diagnosticados como portadores ou não de esteatose hepática não-alcoólica pela ultrassonografia e submetidos à avaliação da força muscular dos membros superiores e inferiores. Os dados foram inseridos no programa estatístico SPSS 22.0, analisados através do teste ANCOVA e pós-teste de Bonferroni, sendo considerado significante P<0,05. RESULTADOS: Foram avaliados pela ultrassonografia abdominal 102 pacientes e destes, 57,8% apresentaram algum grau de esteatose hepática não-alcoólica. A presença e os graus da infiltração gordurosa no fígado tiveram associação estatisticamente significativa com o índice sarcopênico, determinado pela razão entre força muscular dos membros superiores e inferiores e o IMC (P=0,009 e pós-teste P=0,028 MMSS; P=0,006 e pós-teste P=0,013 MMII). CONCLUSÃO: Observou-se associação entre o índice sarcopênico e a presença de esteatose hepática não-alcoólica, com relação inversamente proporcional entre esse índice e a gravidade da infiltração gordurosa, reforçando a interação do eixo metabólico entre fígado, tecido adiposo e músculo.

ABSTRACT

ABSTRACT BACKGROUND: The introduction of anti-TNF agents represented a landmark in the management of both Crohn's disease (CD) and ulcerative colitis (UC), with improved efficacy and safety when compared with conventional treatment. However, significant challenges still exist in Latin America to facilitate the access of biological agents for physicians and patients. OBJECTIVE: The aim of this review was to summarize current evidence on penetration of biological agents for CD and UC in Latin America. METHODS: Data are derived from a previous complete systematic review that explored different characteristics of inflammatory bowel diseases (IBD) in Latin America. The studies fully included in this previous systematic review which contained detailed descriptions of the percentage of use of biological agents in different cohorts throughout Latin American and Caribbean countries were included, and descriptive findings were compiled, describing CD and UC penetration of these drugs in different patient cohorts from different countries. RESULTS: From the 61 studies included in the original systematic review, only 19 included data of the percentage of patients treated with biological agents. Anti-TNF use in CD varied from 1.51% in Mexico up to 46.9% in Colombia, with most of the studies describing anti-TNF use in approximately 20%-40% of CD patients. On the other side, the frequency of the use of biologics was clearly lower in UC, varying from 0% in 2009 to up 16.2% in 2018, according to two different Mexican studies. Only two studies described the penetration of anti-TNF agents in IBD overall: 13.4% in a Colombian and 37.93% in a Brazilian study. No studies described percentage of use of new biologic agents (vedolizumab and ustekinumab). CONCLUSION: Penetration of anti-TNF agents in Latin America is comparable to the rest of the world in CD, but lower in UC. With the increase in the incidence and prevalence of IBD, specific strategies to increase access to anti-TNF agents in UC and new biological agents overall are warranted.


RESUMO CONTEXTO: A introdução dos agentes anti-TNF representou um marco no tratamento da doença de Crohn (DC) e da recocolite ulcerativa (RCU), com maior eficácia e segurança quando comparado ao tratamento convencional. No entanto, ainda existem desafios significativos na América Latina para facilitar o acesso dos agentes biológicos a médicos e pacientes. OBJETIVO: O objetivo desta revisão foi reunir as evidências atuais sobre a penetração de agentes biológicos para DC e RCU na América Latina. MÉTODOS: Os dados são derivados de uma revisão sistemática previamente publicada que explorou diferentes características das doenças inflamatórias intestinais (DII) na América Latina. Os estudos incluídos nesta revisão sistemática anterior que continham descrições detalhadas da percentagem do uso de agentes biológicos em coortes de pacientes em diferentes países da América Latina e Caribe foram incluídos, e os achados descritivos foram compilados detalhando a penetração destes medicamentos no manejo das DII. RESULTADOS: Dos 61 estudos incluídos na revisão sistemática original, apenas 19 incluíram dados de percentagem de pacientes tratados com agentes biológicos. O uso de anti-TNF na DC variou de 1,51% no México até 46,9% na Colômbia, com a maioria dos estudos descrevendo o uso em aproximadamente 20%-40% dos pacientes na DC. Por outro lado, a frequência do uso de biológicos foi claramente menor na RCU, variando de 0% em 2009 a 16,2% em 2018, de acordo com dois estudos mexicanos. Apenas dois estudos descreveram a penetração de agentes anti-TNF nas DII em geral: 13,4% em estudo colombiano e 37,93% em outro estudo brasileiro. Nenhum estudo descreveu o percentual de uso de novos agentes biológicos (vedulizumabe e ustekinumabe). CONCLUSÃO: A penetração de agentes anti-TNF na América Latina é comparável ao resto do mundo na DC, mas menor na RCU. Com o aumento da incidência e prevalência de DII, estratégias específicas para se aumentar o acesso a agentes anti-TNF na RCU e novos agentes biológicos nas DII em geral são justificadas.

ABSTRACT

There is scarce knowledge on early intestinal obstruction in Crohn's disease (CD) after infliximab treatment. Therefore, we describe two cases of early intestinal obstruction in a series of 46 CD patients treated with infliximab. Both our two cases were 21-year-old men with newly diagnosed CD who were diagnosed with perianal disease 2 years previously. They were suffering from diarrhea and abdominal pain, but there were no symptoms indicating bowel obstruction. Radiographic studies revealed stenotic sites in the terminal ileum in both cases. In both cases, infliximab 300 mg was infused, after which their abnormal laboratory data as well as symptoms such as diarrhea and abdominal pain clearly improved. However, on the 11th or 13th day post-treatment, they presented abdominal distension with air-fluid levels on imaging studies. Ileocolonic resection was performed in both cases. Early intestinal obstruction after infliximab therapy is characterized by initial improvement of the symptoms and the laboratory data, which is soon followed by clinical deterioration. This outcome indicates that infliximab is so swiftly effective that the healing process tapers the stenotic site, resulting in bowel obstruction. Thus, although unpleasant and severe, the obstruction cannot be considered as a side effect but rather a consequence of infliximab's efficacy. CD patients with intestinal stricture, particularly the penetrating type with stricture, should be well informed about the risk of developing intestinal obstruction after infliximab therapy and the eventual need for surgical intervention

ABSTRACT

OBJECTIVES: The aim of this study was to evaluate the quantitative serum level of infliximab (IFX) as well as the detection of anti-infliximab antibodies (ATIs) in patients with Crohn's disease (CD). METHOD: Forty patients with CD under treatment at a tertiary center in southeastern Brazil were evaluated. Their use of infliximab was continuous and regular. We analyzed and compared the differences in the IFX and ATI levels between the patients with active CD (CDA) and those with CD in remission (CDR). RESULTS: There was no difference in the IFX level between the CDA and CDR groups (p>0.05). Eighty percent of all patients had IFX levels above the therapeutic concentration (6-10 μg/mL). Two (9%) of the 22 patients with active disease and four (22.2%) of the 18 patients in remission had undetectable levels of IFX. Four (66.6%) of the six patients with undetectable levels of IFX had positive ATI levels; three of these patients were in remission, and one had active disease. In addition, the other two patients with undetectable levels of IFX presented ATI levels close to positivity (2.7 and 2.8 AU/ml). None of the patients with therapeutic or supratherapeutic IFX levels had positive ATI levels. CONCLUSIONS: The undetectable levels of IFX correlated with the detection of ATIs, which was independent of disease activity. Immunogenicity was not the main factor for the loss of response to IFX in our study, and the majority of patients in both groups (CDA and CDR) had supratherapeutic levels of IFX.

ABSTRACT

Background: Primary non-response and secondary loss of response (LOR) are significant problems of biological therapy for inflammatory bowel disease (IBD). Therapeutic drug monitoring (TDM) in IBD patients receiving these drugs can improve outcomes. Aim: To measure serum infliximab levels and anti-infliximab antibodies (ATI) in patients with IBD post-induction phase and during maintenance therapy assessing the clinical course of IBD. Patients and Methods: Prospective study of IBD patients receiving infliximab between July 2016-May 2017. Group-A included patients who received induction therapy while Group-B included patients who were in maintenance therapy. TDM was performed in serum samples collected at weeks-14 and 30 in Group-A and before the infliximab maintenance dose in Group-B. Clinical scores, fecal calprotectin and endoscopic score were also evaluated. Results: Of 14 patients in Group-A, 57% achieved endoscopic response. Median serum infliximab concentrations at week-14 and 30 were 2.65 AU/mL (0.23-32.58) and 2.3 AU/mL (0.3-16.8), respectively. Patients with mucosal healing had non-significantly higher median infliximab concentrations at week- 14, as compared to week 30 (median 3.2 vs 2.2 AU/ml, respectively, p 0.6). ATI >10 ug/mL were found in one and seven patients at week-14 and 30, respectively. At 52 weeks of follow-up, four patients (31%) had LOR. Group-B included 36 patients, 33% had LOR. Median serum concentrations of infliximab were 1.4 AU/mL (0.27-7.03). No significant differences in serum infliximab concentration were observed between patients in remission and those with inflammatory activity. Seventeen patients had ATI >10 ug/mL. Conclusions: Clinical algorithms using TDM might help to optimize the pharmacological therapy of IBD.

ABSTRACT

Inflammatory bowel disease (IBD) has been associated with the development of both gastrointestinal and extraintestinal malignancy. The role of therapy in the development of malignancy in IBD has been controversial. We present the case of a 40-year-old female patient with long-standing mild IBD, who developed an undifferentiated pleomorphic sarcoma of the inguinal region and provide a brief review of the relevant literature. While our case likely represents a coincidence of two unrelated pathological entities, clinicians should keep in mind the possibility of soft tissue sarcomas in patients chronically treated with anti-inflammatory agents.

ABSTRACT

Biological therapies have been essential for the management of inflammatory bowel disease; however, their high cost results in many patients being unable to access them. With time, commercial patents of many "original" biologics are reaching or almost in the point of reaching the expiration date of their licenses, which has allowed for the development of new agents known as biosimilars leading to a reduction of the cost of these therapies. The objective of this review is to explain what biosimilars are and show evidence of their effectiveness and safety.


Las terapias biológicas son parte fundamental en el manejo de la enfermedad inflamatoria intestinal, sin embargo los costos de éstas han hecho que muchos de los pacientes que tienen indicación de su uso, no puedan utilizarlas. Con el paso del tiempo, muchos biológicos "originales" están alcanzando o a punto de alcanzar el vencimiento de sus patentes, lo que ha llevado al desarrollo de nuevos agentes conocidos como biosimilares, determinando una disminución en los costos de estas terapias. Esta revisión tiene como objetivo explicar en qué consisten los biosimilares y la evidencia actual con respecto a su eficacia y seguridad.

ABSTRACT

ABSTRACT BACKGROUND: Infliximab and adalimumab are considered effective drugs in the management of Crohn's disease. However, due to significant immunossupression, they can cause important adverse events, mostly infections. OBJECTIVE: The aim of this study was to quantify and describe adverse events derived from adalimumab and infliximab use in Crohn's disease patients, and to compare the safety profile between these two agents. METHODS: This was an observational, single-center, longitudinal, retrospective study with Crohn's disease patients under infliximab or adalimumab therapy. Variables analyzed: demographic characteristics (including the Montreal classification), type of agent used, concomitant immunomodulators, presence and types of adverse events observed. Patients were allocated in two groups (infliximab and adalimumab) and had their adverse events accessed and subsequently compared. RESULTS: A total of 130 patients were included (68 in infliximab and 62 in adalimumab groups, respectively). The groups were fully homogeneous in all baseline characteristics, with a median follow-up of 47.21±36.52 months in the infliximab group and 47.79±35.09 in the adalimumab group (P=0.512). Adverse events were found in 43/68 (63.2%) and 40/62 (64.5%) in each group, respectively (P=0.879). There were no differences between the groups regarding infections (P=0.094) or treatment interruption (P=0.091). There were higher rates of infusion reactions in the infliximab group (P=0.016). Cephalea and injection site reactions were more prevalent in adalimumab patients. CONCLUSION: Adverse events were found in approximately two thirds of Crohn's disease patients under anti-TNF therapy, and there were no significant differences between infliximab or adalimumab.


RESUMO CONTEXTO: A utilização de inibidores do fator de necrose tumoral (TNF) alfa no manejo da doença de Crohn é cada vez mais frequente. Tanto o infliximabe quanto o adalimumabe são considerados medicamentos efetivos no controle da doença. Entretanto, por serem potentes imunossupressores, podem causar efeitos adversos importantes, principalmente infecções. OBJETIVO: O objetivo primário deste estudo foi analisar a presença de efeitos adversos dos anti-TNFs em portadores de doença de Crohn, comparando-se infliximabe e adalimumabe e individualizando-se o perfil de segurança de cada droga. MÉTODOS: Estudo observacional, longitudinal e retrospectivo, que incluiu portadores de doença de Crohn com uso de infliximabe ou adalimumabe de uma coorte de pacientes tratados em um único centro. Analisou-se características demográficas (incluindo-se a classificação de Montreal), tipo de agente utilizado, presença e tipo dos eventos adversos observados, entre outras variáveis. Os pacientes foram alocados em dois grupos (infliximabe e adalimumabe) e tiveram os efeitos adversos anotados e posteriormente comparados. RESULTADOS: Um total de 130 pacientes foram incluídos (68 com infliximabe e 62 com adalimumabe). Os grupos foram homogêneos em todas as variáveis analisadas, com tempo de seguimento médio de 47,21±36,52 meses no grupo infliximabe e 47,79±35,09 no grupo adalimumabe (P=0,512). Efeitos adversos foram encontrados em 43/68 (63,2%) e 40/62 (64,5%) nos dois grupos, respectivamente (P=0,879). Não houve diferença entre os grupos em relação a infecções (P=0,094) ou interrupção do tratamento (P=0,091). Houve maiores índices de reações infusionais no grupo infliximabe (P=0,016). Cefaleia e reações no local das injeções foram mais frequentes no grupo adalimumabe. CONCLUSÃO: Efeitos adversos foram encontrados em cerca de dois terços dos pacientes com doença de Crohn em uso de anti-TNF, não havendo maiores diferenças em relação ao uso de infliximabe ou adalimumabe.

ABSTRACT

ABSTRACT BACKGROUND: Crohn's disease and ulcerative colitis are chronic inflammatory bowel diseases. In such pathologies, there is an increased production of alpha tumor necrosis factor (TNF-α). Patients, in whom the conventional immunosuppressant treatment fails, require the use of immunobiological therapy, such as anti-TNF-α, a monoclonal antibody. Infliximab is an anti-TNF-α drug, a chimerical immunoglobulin, with a murine component, which is responsible for the generation of immunogenicity against the drug and formation of anti-TNF-α antibodies. The presence of anti-drug antibodies may be responsible for adverse events and reduction of the drug's effectiveness. Patients with inflammatory bowel diseases undergoing therapy with biological medication, such as infliximab, can relapse overtime and this may not be translated into clinical symptoms. Thus, there is a need for a method to evaluate the efficacy of the drug, through the measurement of serum infliximab levels, as well as antibodies research. OBJECTIVE: This study aimed to measure serum infliximab levels and anti-infliximab antibodies in patients with inflammatory bowel diseases post-induction phase and during maintenance therapy, and describe the therapeutic modifications that took place based on the serum levels results. METHODS: It was a retrospective study, that included forty-five patients, with a total of 63 samples of infliximab measurement. RESULTS: Twenty-one patients had an adequate infliximab serum level, 31 had subtherapeutic levels and 11 had supratherapeutic levels. Seven patients had their medication suspended due to therapeutic failure or high levels of antibodies to infliximab. CONCLUSION: In conclusion, only a third of the patients had adequate infliximab levels and 36% presented with subtherapeutic levels at the end of the induction phase. Therapy optimization occurred based in about 46% of the samples results, demonstrating the importance of having this tool to help the clinical handling of patients with inflammatory bowel diseases ongoing biologic therapy.


RESUMO CONTEÚDO: Doença de Crohn e retocolite ulcerativa são doenças inflamatórias intestinais crônicas. Nelas, ocorre aumento da produção de fator de necrose tumoral alfa (TNF-α). Pacientes que falham no tratamento convencional imunossupressor, requerem uso de terapia imunobio­lógica, que são anticorpos monoclonais, principalmente os anti-TNF-α. O infliximabe é uma droga anti-TNF-α, uma imunoglobulina quimérica, com componente murino. Este é responsável pela imunogenicidade da droga e a formação de anticorpos. Presença de anticorpos antidroga pode ser responsável pelos eventos adversos e redução da eficácia da droga. Pacientes com doenças inflamatórias intestinais, em terapia imunossupressora com medicação biológica como o infliximabe, podem ter recaída da doença e muitas vezes isso não se relaciona com a sintomatologia do paciente. Por isso há a necessidade de um método de avaliação do efeito da droga como a dosagem do nivel sérico do infliximabe, bem como da pesquisa de anticorpos. OBJETIVO: O estudo tem como objetivo conhecer os níveis séricos do infliximabe e dos anticorpos anti-infliximabe em pacientes com doença inflamatória intestinal em terapia de manutenção ou pós-indução e descrever as condutas terapêuticas que foram modificadas em função dos níveis séricos de infliximabe e anticorpos para infliximabe. MÉTODOS: Trata-se de estudo restrospectivo, com análise da dosagem dos níveis séricos de infliximabe e anticorpos para Infliximabe. Foram incluídos 45 pacientes, num total de 63 coletas de dosagem de infliximabe. RESULTADOS: Vinte e um paciente estavam com o nível sérico de infliximabe adequado, níveis subterapêuticos em 31 pacientes e níveis supraterapêuticos em 11 pacientes. Sete pacientes tiveram a medicação suspensa por falha terapêutica ou altos níveis de anticorpos para infliximabe. CONCLUSÃO: Apenas um terço dos pacientes apresentavam níveis adequados de infliximabe e 36% dos pacientes apresentavam níveis subterapêuticos ao término da indução. Em cerca de 46% das amostras a conduta adotada se baseou nos níveis de infliximabe e anticorpos para infliximabe demonstrando a importância de se ter esta ferramenta para auxílio no manejo clínico dos pacientes portadores de doenças inflamatórias intestinais em terapia biológica.

ABSTRACT

Los fármacos anti factor de necrosis tumoral alfa (TNF-α) bloquean una de las citoquinas implicadas en la patogénesis de la Enfermedad Inflamatoria intestinal (EII). Su uso se relaciona con aumento de tuberculosis (TB), por lo que el despistaje previo es obligatorio. En la infección tuberculosa latente (ITBL) se utiliza isoniazida como quimioprofilaxis, fármaco que no se encuentra libre de reacciones adversas. Se presenta y discute el caso de una paciente con reacción adversa en piel secundaria al uso de isoniazida.


Anti-tumor necrosis factor alfa drugs are responsible for blocking one of the cytoquines implicated on inflammatory bowel disease pathogenesis. Its use has been linked to an increase in tuberculosis cases which is why screening before starting treatment is mandatory. Latent tuberculosis is treated with isoniazid as chemoprophylaxis although its use may provoke adverse effects. A case is presented of a patient with skin adverse reaction due to the use of isoniazid.
