Linear growth and bone metabolism in pediatric patients with inflammatory bowel disease / Crescimento linear e metabolismo ósseo em pacientes pediátricos com doença inflamatória intestinal

Abstract Objective: To review the pathophysiology and evaluation methods of linear growth and bone mineral density in children and adolescents diagnosed with inflammatory bowel disease. Source of data: Narrative review carried out in the PubMed and Scopus databases through an active search of the terms: inflammatory bowel disease, growth, failure to thrive, bone health, bone mineral density, and children and adolescents, related to the last ten years, searching in the title, abstract, or keyword fields. Synthesis of findings: Inflammatory bowel diseases of childhood onset may present as part of the clinical picture of delayed linear growth in addition to low bone mineral density. The presence of a chronic inflammatory process with elevated serum levels of inflammatory cytokines negatively interferes with the growth rate and bone metabolism regulation, in addition to increasing energy expenditure, compromising nutrient absorption, and favoring intestinal protein losses. Another important factor is the chronic use of glucocorticoids, which decreases the secretion of growth hormone and the gonadotrophin pulses, causing pubertal and growth spurt delay. In addition to these effects, they inhibit the replication of osteoblastic lineage cells and stimulate osteoclastogenesis. Conclusion: Insufficient growth and low bone mineral density in pediatric patients with inflammatory bowel disease are complex problems that result from multiple factors including chronic inflammation, malnutrition, decreased physical activity, late puberty, genetic susceptibility, and immunosuppressive therapies, such as glucocorticoids.

Resumo Objetivo: Revisar a fisiopatologia e os métodos de avaliação do crescimento linear e densidade mineral óssea em crianças e adolescentes com diagnóstico de doença inflamatória intestinal. Fontes dos dados: Revisão narrativa a partir de pesquisa nas bases de dados PubMed e Scopus por meio de busca ativa dos termos inflammatory bowel disease, growth, failure to thrive, bone health, bone mineral density, children e adolescents nos últimos dez anos e com busca nos campos título, resumo ou palavra-chave. Resumo dos achados: As doenças inflamatórias intestinais com início na infância podem apresentar como parte do quadro clínico atraso do crescimento linear, além de baixa densidade mineral óssea. A presença de processo inflamatório crônico com elevados níveis séricos das citocinas inflamatórias interfere negativamente na velocidade do crescimento e na regulação do metabolismo ósseo, além de aumentar o gasto energético, comprometer a absorção de nutrientes e favorecer perdas proteicas intestinais. Outro fator importante é o uso crônico de glicocorticoides, que diminuem a secreção de hormônio do crescimento e dos pulsos das gonadotrofinas e ocasionam atraso puberal e no estirão do crescimento. Além desses efeitos, inibem a reprodução das células da linhagem osteoblástica e estimulam a osteoclastogênese. Conclusão: A insuficiência do crescimento e a baixa densidade mineral óssea em pacientes pediátricos com doença inflamatória intestinal são problemas complexos e que decorrem de múltiplos fatores, inclusive inflamação crônica, desnutrição, diminuição da atividade física, puberdade tardia, suscetibilidade genética a terapias imunossupressoras, como os glicocorticoides.

IBD is a group of diseases that generate limitation and disability diminishing the quality of life of patients(AU)

Epidemiological profile and clinical characteristics of patients with intestinal inflammatory disease / Perfil epidemiológico e características clínicas dos pacientes com doença inflamatória intestinal

ABSTRACT According to several epidemiological studies, there is a significant increase in cases of inflammatory disease in developing countries. Objective: To describe epidemiological data and clinical features of patients with inflammatory bowel disease in patients enrolled in Campo Grande, MS. Method: A retrospective descriptive study with a database analysis of patients who were enrolled and renewed their process in the Exceptional Medications Program of the Health Department from January 2008 to December 2016. Results: 423 patients participated in the study, 260 women and 163 men. Of these, 238 patients had Crohn's disease and 185 had ulcerative rectocolitis. The patients' mean age was 46 years. The most commonly used medication for both diseases was mesalazine and 34.3% of the patients needed to switch their medication during the treatment, most of them with Crohn's disease. In Crohn's patients, the most affected segment was the colon (40.6%) and in patients with ulcerative rectocolitis the entire large intestine was involved (78.8%) was more common. Of the total number of patients, 10.8% of the women and 18.4% of the men needed to use an anti-TNF. Conclusion: Most people on treatment for IBD are female, with a mean age of 46 years and suffering from Crohn's disease. The most affected segments were the entire large intestine in URC cases and the colon in Crohn's disease cases. Mesalazine was the most used drug in both diseases. There was more drug replacement in Crohn's disease patients. In Crohn's disease, younger patients used infliximab more frequently.

RESUMO De acordo com vários estudos epidemiológicos, há aumento significativo de casos de doença inflamatória nos países em desenvolvimento. Objetivo: Descrever os dados epidemiológicos e características clinicas dos pacientes com doença inflamatória intestinal em Campo Grande - MS. Método: Pesquisa descritiva retrospectiva, com análise dos prontuários em banco de dados, em pacientes que cadastraram e renovaram o processo no Programa de Medicamentos Excepcionais da Secretaria de Saúde, de janeiro de 2008 e dezembro de 2016. Resultados: Participaram da pesquisa 423 pacientes, 260 mulheres e 163 homens. Deste total, 238 possuíam doença de Crohn e 185 Retocolite Ulcerativa. A média de idade foi de 46 anos. O medicamento mais utilizado em ambas doenças foi a mesalazina e 34,3% dos pacientes necessitaram realizar troca de medicamentos ao longo do tratamento, sendo a maioria portador da doença de Crohn. Nos pacientes com Crohn o segmento mais acometido foi o cólon (40,6%) e nos pacientes com RCU foi todo o intestino grosso (78,8%). Do total de pacientes, 10,8% das mulheres e 18,4% dos homens necessitaram utilizar anti-TNF. Conclusão: A maioria das pessoas em tratamento para DII são do sexo feminino, com média de idade de 46 anos e portadores de Doença de Crohn. Os segmentos mais acometidos na RCU foi todo o intestino grosso e na Doença de Crohn o colo. A mesalazina foi o medicamento mais utilizado em ambas as doenças.

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.

Obesidad y enfermedad inflamatoria intestinal / Obesity and inflammatory bowel disease

Incidence of obesity is rising worldwide, Chile is no exception with obese patients representing up to one third of general population. This parallels with increasing prevalence of inflammatory bowel disease (IBD). Contrary to conventional belief, comorbidity is high (15-40%), where both diseases present with chronic inflammation and dysbiosis which alters intestinal barrier. Causality between obesity and IBD is difficult to stablish and evidence is scarce to determine association. Obesity would be a risk factor for IBD, particularly in Crohn´s Disease (CD), females and obesity at young age. Other than body mass index (BMI), visceral adipose tissue (VAT) has been recently determined as the best indicator of metabolic and endocrine consequences of obesity. Increasing values of VAT have been related to complicated IBD and worst prognosis. On IBD-related therapy, increasing BMI has been related to suboptimal doses and in biologic therapy, obesity raises the probability of flares, loss of response and therapy optimization. Obese patients require IBD-related surgery before non-obese patients and present more postoperative complications. Similarly, VAT is an independent risk factor for postoperative recurrence in CD. Altogether this evidence suggests that obesity does have an influence on IBD, therefore, multidisciplinary healthcare providers should prevent, educate and intervene actively in obesity in order to improve results in intestinal disease

La obesidad ha ido aumentando progresivamente a nivel mundial. Chile no es la excepción, donde un tercio de la población es obesa. Así mismo, la incidencia y prevalencia de la enfermedad inflamatoria intestinal (EII) también ha ido en aumento. La comorbilidad entre obesidad y EII es alta (15-40%) donde ambas presentan inflamación crónica y dentro de su patogenia tienen en común la disbiosis, que altera la función de barrera intestinal. Establecer una asociación de causalidad es difícil y la evidencia es escasa en relación a su asociación. La obesidad puede ser considerada como factor de riesgo para EII, particularmente en pacientes con Enfermedad de Crohn (EC), mujeres y obesidad temprana. Además, se ha establecido que el tejido adiposo visceral (TAV) es mejor indicador de las consecuencias metabólicas de la obesidad en comparación al índice de masa corporal (IMC) y se ha asociado a EII más complicada y peor evolución natural. Con respecto a la terapia, los pacientes con mayor IMC tienen con mayor frecuencia, dosis subóptima de los fármacos, y en terapia biológica, la obesidad aumenta la probabilidad de crisis, pérdida de respuesta al fármaco u optimización de la terapia. Los pacientes obesos requieren cirugía relacionada a EII antes que los pacientes no obesos, presentan más complicaciones postoperatorias y el TAV es un factor de riesgo independiente para recurrencia postoperatoria en EC. Todos estos resultados sugieren que la obesidad influye en la EII, por lo que una intervención activa y multidisciplinaria pudiese mejorar también los resultados en la enfermedad intestinal.

Manejo integral de la enfermedad inflamatoria intestinal: más allá de una terapia farmacológica adecuada / Towards an integral management of inflammatory bowel disease

Inflammatory Bowel Disease (IBD) is a chronic inflammatory condition of the gastrointestinal tract with medical and psychological complications. Addressing psychosocial aspects of treatment, such as quality of care and disability remains a challenge. The quality of care for IBD patients is not optimal at the present time and there is a variation in the care provided by specialists. Therefore, it is necessary to develop well defined quality indicators to assure the delivery of an adequate care to these patients. The delivery of healthcare for IBD patients is often complex and requires multidisciplinary teams. The ultimate objectives in the treatment of IBD should be to prevent bowel damage, reduce long-term disability and maintain a normal quality of life.

Enfermedad inflamatoria intestinal y embarazo: experiencia de 16 años / Pregnancy and inflammatory bowel disease: Experience in 17 patients

Background: Inflammatory bowel disease (IBD) has a peak incidence between 15 and 25 years of age, thereby affecting women of reproductive age. Fertility rates with inactive IBD are similar to the general population, and drugs currently used, with the exception of methotrexate and thalidomide, have a good safety and efficacy profile during pregnancy. Starting a pregnancy with inactive IBD significantly reduces the potential maternal and fetal complications. Aim: To assess the evolution of pregnancy and the underlying disease in women with IBD. Patients and Methods: Retrospective and prospective study of female patients with IBD controlled in our hospital who became pregnant from January 1994 to February, 2011. Results: We followed 17patients with a total of 19 pregnancies. In two patients the onset of IBD occurred during pregnancy and from the remaining, 11 patients became pregnant during remission of IBD. Most of the patients continued the same treatment during pregnancy and the few flares that occurred were treated satisfactorily. Major complications occurred in three patients, all associated with IBD activity. Fifteen patients had full-term deliveries and the majority of the newborns had normal weight and Apgar score. None had malformations. Conclusions: Pregnancies among patients with an inactive IBD, have a good evolution. A multidisciplinary approach and patient education are invaluable to achieve these good results.

Pulmonary function test results in patients with ulcerative colitis

Pulmonary complication of IBD includes airway inflammation involving small and large airways, pulmonary paranchymal disease and serositis. The aim of this study was to determine the prevalence of Pulmonary Function Test [PFT] abnormality in ulcerative colitis [UC] patients. During spring and summer of 2006, PFT [spirometry and body box plethysmography] of 50 UC patients were compared with 50 healthy persons matched for age and sex [control]. Data collection form including demographic specification and UC condition were filled. Mean age of patients was 37.2 years [SD=14.5]. Active UC was seen in 24% of patients while 18% of patients suffered from severe UC. PFT results included 42% air trapping [only increase in residual volume/total lung capacity], 20% small airway obstructive pattern [only decrease in maximal expiratory flow at 25-75% of vital capacity], 12% restrictive ventilation defect, 2% obstructive airway, 2% hyperinflation and 6% upper airway obstructive pattern. There was a significant relationship between small airway obstructive pattern and duration of UC and no relationship was noticed between other pulmonary disorders and severity, activity, duration of UC. According to high prevalence of air trapping, small airway disease may be the prominent feature of lung involvement in UC patients. Therefore a meticulous work up for respiratory diseases is necessary in UC patients

Tratamento com hormônio de crescimento em crianças com doenças crônicas: [revisão] / Growth hormone therapy for children with chronic diseases: [review]

Crianças com doenças crônicas freqüentemente apresentam crescimento inadequado e baixa estatura. A falência do crescimento é multifatorial. Nas doenças inflamatórias, como na artrite juvenil idiopática e nas doenças inflamatórias intestinais, o crescimento é comprometido também pelo processo inflamatório. Muitas vezes, o tratamento da doença de base compromete o crescimento, especialmente quando é necessário glicocorticóides. Em algumas situações é possível comprovar a deficiência associada de hormônio de crescimento (GH, do inglês growth hormone). Em outras, os exames sugerem certo grau de insensibilidade ao GH. O tratamento destes pacientes com GH tem se mostrado útil e seguro com melhora do crescimento e da qualidade de vida. Nesta revisão, são apresentados resultados do tratamento com GH em pacientes com baixa estatura decorrente de doenças crônicas, algumas indicações já bem definidas e outras ainda em investigação.

Growth disorders are commonly observed in children suffering from chronic diseases. The pathogenesis of growth failure is multifactorial. In chronic inflammatory diseases such as juvenile idiopathic arthritis and inflammatory bowel disease, growth is also affected by pro-inflammatory cytokines. Patients with chronic diseases might also become growth hormone (GH) deficient. However, normal or increased GH secretion with reduced plasma concentrations of insulin-like growth factor-I indicate a degree of GH insensitivity in some patients. Growth damage can increase with specific treatments, especially if glucocorticoids are used. GH therapy has been used to reduce the consequences of the disease and long-term steroid therapy in these patients. In this review, it is reported the encouraging results of GH treatment in growth-retarded children with chronic diseases, both in well defined indications as well in situations still under investigation.

Constipación: ¿síntoma de enfermedad funcional? ¿Detección precoz del cáncer? / Constipation: symptom of a functional disease? Early cancer detection?

Constipation is one of the most common digestive complaints. Despite this constipation receives less attention than other digestive problems, and usually is self-diagnosed and self-medicated. Constipation can be defined as a symptomatic decrease in frequency of bowel movements. In occasions, this complaint can course as a benign pathoogy, with an easy management. Otherwise, simple constipation, in other times, can be converted in a severe disease, even in a threatening process, which can be a danger for the life of the patient...

El kininógeno de alto peso molecular: su participación en la respuesta inflamatoria y en la angiogénesis. Propiedades y posible aplicación terapéutica / High molecular weight kininogen in inflammation and angiogenesis: a review of its properties and therapeutic applications

The plasma kallikrein-kinin system (KKS) participates in the pathogenesis of inflammatory reactions involved in cellular injury, coagulation, fibrinolysis, kinin formation, complement activation, cytokine secretion and release of proteases. It has been shown that KKS activation in the systemic inflammatory response syndrome results in decrease of its component plasma proteins. Similar changes have been documented in diabetes, sepsis, children with vasculitis, allograft rejection, disseminated intravascular coagulation, patients with recurrent pregnancy losses, hereditary angioedema, adult respiratory distress syndrome and coronary artery disease. Direct involvement of the KKS in the pathogenesis of experimental acute arthritis and acute and chronic enterocolitis has been documented by previous studies from our laboratory using experimental animal models. It has been found that in HK deficient Lewis rats, experimental IBD was much less severe. We showed a genetic difference in kininogen structure between resistant Buffalo and susceptible Lewis rats, which results in accelerated cleavage of HK and it is responsible for the susceptibility to the inflammatory process in the Lewis rats. It has been demostrated that therapy with a specific plasma kallikrein inhibitor (P8720) modulated the experimental enterocolitis, arthritis and systemic inflammation. Furthermore, it has been shown that a bradykinin 2 receptor (B2R) antagonist attenuates the inflammatory changes in the same animal model. We have showed that a monoclonal antibody targeting HK decreases angiogénesis and arrests tumor growth in a syngeneic animal model. In summary, these results indicate that the plasma KKS plays a central role in the pathogenesis of chronic intestinal inflammation, arthritis and angiogenesis.

Se ha demostrado la participación del sistema plasmático de kalikreína-kininas (KKS) en el proceso inflamatorio, el cual incluye reacciones de daño celular, coagulación y fibrinólisis, formación de kininas, activación del complemento, secreción de citoquinas y liberación de proteasas. El KKS se encuentra activado en el síndrome de respuesta inflamatoria sistémica con una disminución en la concentración plasmática de las proteínas que lo constituyen. También se ha demostrado una activación similar en la diabetes, choque séptico, vasculitis en infantes, enfermedad injerto-huésped, coagulación intravascular diseminada, pacientes con abortos de repetición, angioedema hereditario, el síndrome de estrés respiratorio del adulto y enfermedad coronaria arterial. Mediante el uso de modelos animales experimentales, nuestro laboratorio ha demostrado una participación directa del KKS en la patogénesis de la artritis experimental aguda y la enterocolitis aguda y crónica. Se ha demostrado que en la rata tipo Lewis, cuando es deficiente de kininógeno de alto peso molecular (HK), la enfermedad inflamatoria intestinal es menos severa comparada con la presentada en ratas con niveles normales de HK como la Buffalo. Nosotros mostramos una diferencia entre el gene que codifica la molécula del kininógeno de la rata tipo Buffalo (resistentes) y Lewis (susceptibles), que resulta en un incremento de la actividad proteolítica de kalikreína sobre su substrato HK, lo cual predispone a las ratas Lewis al desarrollo de la enfermedad inflamatoria crónica. Se ha demostrado una disminución en las manifestaciones inflamatorias sistémicas de la enterocolitis y artritis experimental mediante el uso de un inhibidor específico de la kalikreína (P8720). Además, el antagonista del receptor 2 de la bradikinina (BR2) atenuó los cambios inflamatorios en el mismo modelo animal. Asimismo, se ha demostrado que las ratas Lewis deficientes de kininógeno desarrollaron inflamación intestinal sistémica menos severa. Mediante el uso del anticuerpo monoclonal C11C1 contra HK se logró una disminución de la angiogenesis y, consecuentemente, el crecimiento tumoral. En conclusión, los resultados demuestran que el sistema plasmático de KKS desempeña un papel preponderante en la patogénesis de la artritis reumatoide, la enfermedad intestinal crónica y en el proceso angiogénico.

Enfermedades inflamatorias intestinales: experiencia de dos centros chilenos / Inflammatory bowel disease: experience of two chilean centers

Background: The incidence of Inflammatory Bowel Disease (IBD) has increased, particularly in the developed world, and probably also in Chile. Aim: To report our experience with a large group of patients from two medical centers, Hospital Clinico de la Universidad de Chile (HCUCH) and Clinica Las Condes (CLC) and to characterize the clinical features of IBD in Chile. Patients and methods: Retrospective review of 238 patients with IBD (age range 14-78 years, 143 women) treated at HCUCH and CLC between January 1990 and August 2002. Results: One hundred eighty one patients had ulcerative colitis (UC) and 57 had Crohn's disease (CD), with an UC/CD ratio of 3.2/1. Forty eight percent of patients were aged between 20 and 39 years old and 69% were diagnosed after 1995. Patients from HCUCH had more severe disease, more complications and needed surgery more often. Conclusions: Clinical features of Chilean patients with IBD are similar to those of other countries. UC is more common than EC. There is a higher proportion of women with the disease. The severity of the disease was higher among HCUCH.

Lymphatic vessel contractile activity and intestinal inflammation

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

Role de la flore intestinale dans les maladies inflammatoires chroniques de l'intestin et place des probiotiques dans leur prise en charge

The pathogenic role of certain microorganisms of intestinal flora has been demonstrated in experimental colitis in animals and strongly suspected in inflammatory bowel disease in human, especially in Crohn's disease and pouchitis. Probiotics are living non pathogenic microorganisms that, upon oral ingestion exert benefits on human health by modulating enteric flora or by stimulation of local immune system. The aim of this article is to remind the role of intestinal flora in inflammatory bowel disease, the mechanism of inflammation induced by this flora and to review through the literature, the different clinical studies performed with probiotics in human

Manifestações extra-intestinais da doença intestinal inflamatória / Manifestations extra-instinal of inflammatory bowel diseases

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

Aspectos nutricionais de pacientes adultos com doença inflamátoria intestinal atendidos em uma unidade de saúde de Salvador / Nutrional aspects of adult inflammatory bowel disease patients seen at a healthcare unit in Salavador

A desnutrição é uma condição comum e de causa multifatorial nos pacientes com doença inflamatória intestinal (DII). O objetivo desse trabalho foi identificar o estado nutriacional e possíveis fatores associados em pacientes com DII atendidos no Ambulatório de Gastroenterologia dos Hospital das Clínicas, Bahia. Em estudo retrospectivo, foram analisadas as fichas de anamnese nutricional de 45 pacientes adultos com diagnóstico de doença de Crohn (DC) e retocolite ulcerativa idiopática (RCUI), onde constavam questões sobre avaliação antropométrica, queixas gastrointestinais, medicamentos em uso e historia alimentar. Na avaliaçãodo índice da massa corpórea (IMC), 70por cento (14/20) dos portadores de DC e 72por cento (18/25) daqueles com RCUI tinham diagnóstico nutricional de eutrofia. No entanto, 47,4por cento (9/19) dos indivíduos com DC e 36por cento (9/25) com RCUI apresentaram circunferência muscular do braço (CMB) abaixo do percentil 10. As queixas gastrointestinais foram maiores: 72,0por cento (18/25) nos pacientes com RCUI comparados com 50,0por cento (10/20) com DC. Restrições alimentares foram relatadas por 76,0 por cento (19/25) dos pacientes com RCUI e 60,0 (12/20) dos com DC. O motivo relatado por 66,6 por cento (16/24) dos pacientes com DII para essas restrições alimentares foi a orientação de profissionais de saúde. Conclui-se que: 1)A desnutrição não foi uma dado frequente nesses pacientes; 2) o IMC isoladamente não caracterizou o estado nutricinal desses pacientes; 3) outros índices antropométricos, com CMB e somatorioPCT + PCSE, permitiram identificar alterações na distribuição corpórea; 4)as restrições alimentares foram comuns; 5) orientações por profissionais de saúde foram causa frequente de restrições alimentares; 6) a atenção nutricional individualizada é importante para melhor acompahamento desses pacientes

Cytokines and inflammatory bowel disease.

Cytokines are the key mediators of inflammation in the IBD and are focus of renewed interest to plan therapeutic strategies against this disease. However, there are gaps in our knowledge at present and a lot of questions need clear answers. Even with a therapy as specific as anti-TNF antibody, it is not clear if the benefit is attributable to simple binding and clearance of TNF-alpha or to binding on the cell surface and subsequent deletion of the activated macrophage. When a drug appears to be less effective than pre-clinical models suggest, can failures in effectiveness from delivery or dosing the differentiated? The disappointing results of clinical trials with IL-10 is at odds with the prediction of benefit from animal models. It even brings into question the validity of those models as well as the soundness of design of the clinical trials on which efficacy of IL-10 is assessed. Other exciting new methods to treat IBD could be use of monoclonal antibodies to effector T cell molecules (such as CD4 or CD44v7) removal of such cytokine secreting cells (apheresis), antibodies to proinflammatory cytokines (such as TNF-alpha, IFN-alpha, IFN-gamma, and IL-12) or administration of anti-inflammatory cytokines (such as IL-10, IL-11). Challenges in developing new therapeutic strategies include not only identifying novel agents, but also improving the definitions of clinical endpoints and defining efficacy at the biologic level. There is also need to further refine our knowledge about genetic elements and environment initiators to comprehensively manage IBD.
