RESUMO

Background: no systematic studies on the prevalence ofcoeliac disease (CD) have been reported from China. In westernpopulations CD is more common in patients with insulin dependentdiabetes mellitus (IDDM) and in diarrhoea-predominant irritablebowel syndrome (D-IBS). We have screened patients withthese conditions presenting to the outpatient department of alarge hospital of “Traditional Chinese Medicine” (TCM) in Nanjing,Jiangsu province, P.R. China.Methods: we tested sera of 78 unrelated Han Chinese patients(5 IDDM and 73 D-IBS), using ELISA serological tests forIgG anti-gliadin antibodies (IgG-AGA) and IgA anti-tissue transglutaminaseantibodies (IgA-tTG).Results: six out of 78 patients (7.7%) were positive for IgGAGA(two men and four women) and two (2.6%) were positive forIgA-tTGs. One of the latter patients was negative for IgG-AGA.Besides, one patient had a dubious IgA-tTG antibody and a positiveIgG-AGA. None of the six patients agreed to undergo duodenalbiopsy. Two out of these six patients followed a gluten-freediet for one year. In one patient the diarrhoea ceased and hisbody weight increased. Another stopped losing weight.Conclusions: this study previously published as a letter inGUT (Wu J, Xia B, von Blomberg BME, Zhao C, Yang XW, CrusiusJBA, Peña AS. Coeliac disease: emerging in China? Gut2010; 59(3): 418-9) demonstrated that CD may exist in theJiangsu province of P.R. China. The present article draws attentionto the difficulties of following a standard protocol in Chinasuch as established in western countries and highlights importantfactors less well known in the west in relation to the developmentof CD in China. Wheat production became significant in Chinabetween 1600 and 1300 B.C. After the Han dynasty (500-200B.C.), wheat was one of the main cereals in China. One the majorwheat fields in China is located in the Jiangsu province where theresearch for this article was performed...(AU)

RESUMO

En esta revisión repasamos los estudios publicados hasta la fechacon las formulaciones orales y las preparaciones tópicas rectales debudesonida (Entocort® y Budenofalk®, en España Entocord® e Intestifalk®) para el tratamiento de la colitis ulcerosa. Este glucocorticosteroidede una elevada acción tópica y un importante metabolismode primer paso hepático se ha utilizado en los últimos años comouna formulación de liberación controlada, proporcionando resultadossimilares a la prednisolona pero sin suprimir de forma apreciablelos niveles de cortisol plasmático. Aunque se han publicado muchosestudios sobre los efectos de la budesonida oral para eltratamiento de la enfermedad de Crohn, los estudios sobre esta mismaforma galénica de administración de budesonida para el tratamientode los pacientes con colitis ulcerosa son escasos. Despuésde revisar los trabajos publicados al respecto, se sugiere la necesidadde realizar un estudio controlado con las nuevas formulaciones debudesonida oral para el tratamiento de la colitis ulcerosa, con el objetivode obtener pruebas sobre la eficacia real de este fármaco parael tratamiento de esta enfermedad


In this review, we examined studies published on oral and topicalformulations of budesonide (Entocort® and Budenofalk®, inSpain: Entocord® and Intestifalk®) for the treatment of ulcerativecolitis. This glycocorticosteroid has a potent local action and animportant first-pass liver metabolism. It has proven successful overthe last years as a controlled-release formulation. It obtained resultssimilar to prednisolone, without the latter’s significant suppressionof plasma cortisol. Many publications exist on the effectsof oral budesonide for the treatment of Crohn’s disease (CD).These have led to the registration of this drug for the treatment ofCD. Studies on oral formulations of budesonide for the treatmentof ulcerative colitis (UC) are scarce. After reviewing published evidence,we suggest the conduction of controlled trials for the treatmentof UC to obtain evidence-based efficacy and safety results inorder to benefit patients with this form of inflammatory bowel disease(IBD)

RESUMO

Objetivo: conocer la influencia de las principales mutacionesdescritas en el gen NOD2/CARD15 en la cirugía asociada a la enfermedadde Crohn.Pacientes y diseño experimental: se estudió un total de165 pacientes con enfermedad de Crohn, analizándose los antecedentesde cirugía de estos pacientes en relación con su enfermedad,se analizaron los antecedentes de cirugía en global e, individualmente,de las dos formas principales de cirugía, resección ilealy cirugía de las fístulas. Se estudió también la necesidad de apendicectomía.Todos los pacientes fueron genotipados para las tresmutaciones del gen CARD15 y se llevaron a cabo estudios de asociaciónmediante el empleo de test Chi cuadrado o test exacto deFisher cuando este fue necesario.Resultados: individuos portadores de las mutaciones G908Ro 1007fs requieren cirugía con mayor frecuencia, tanto sea estaconsiderada de forma global como en resección ileal y cirugía defístulas individualmente. Por el contrario la apendicectomía noaparece asociada significativamente al gen CARD15.Conclusiones: la necesidad de cirugía asociada a enfermedadde Crohn, es mayor en pacientes que portan las mutacionesG908R o 1007fs del gen CARD15. Sin embargo, la mutaciónR702W parece no influir en población gallega. La influencia deesas dos mutaciones no es, sin embargo, suficiente como paraque puedan ser utilizadas con fines predictivos


Objective: the aim of this study is to assess the importance ofNOD2/CARD15 gene mutations as prognostic factors for surgicalindications in Crohn’s disease.Patients and experimental design: a total of 165 Crohn’sdisease patients were studied, considering previous surgery related toCrohn´s disease. We analyzed for previous surgery in global proceduresas well as separately for the two main surgical indications: ilealresection and fistula treatment. The need for appendectomy was alsostudied. All patients were genotyped for the three CARD15 mutations,and association studies were developed using Chi-square statisticsand Fisher’s exact test whenever appropriate.Results: carriers of the G908R or 1007fs mutation neededsurgery more frequently, both for ileal resection and fistula repair.In contrast, appendectomy was not associated with CARD15 mutations.Conclusions: as previously reported in this population, theR702W mutation does influence parameters of disease or need ofsurgery. The need for Crohn’s disease-related surgery is higher incarriers of the G908R or 1007fs CARD15 mutation in the Galicianpopulation. Nevertheless, the frequency of these mutationsdoes not allow their use to predict the course of disease

RESUMO

Arthralgias and spondyloarthropathies of the peripheral andaxial joints are common in inflammatory bowel disease. Evidencefor a strong association between these clinical manifestations anddiseases of the joints has been provided by several clinical and epidemiologicalstudies. Immunological studies have shown the presenceof shared inflammatory cells both in the gut and the synoviumin spondyloarthropathies. Genetic factors play a crucial role inthe pathogenesis of spondyloarthropathies and inflammatorybowel disease. The role of the ubiquitous bacterial flora and pathogenicmicroorganisms present in the intestinal lumen may inducethese joint diseases in patients with inflammatory bowel disease.In this review we will focus on the pathogenesis of spondyloarthropathiesand arthralgia in patients suffering from inflammatorybowel disease. Based on preliminary clinical observations inpatients with arthralgia and IBD, we put forward the hypothesisthat probiotics may be helpful in the management of common extraintestinalmanifestations such as arthralgia in patients with ulcerativecolitis and Crohn’s disease

RESUMO

Aunque en la actualidad la etiología de la enfermedad inflamatoria intestinal (IBD) sigue siendo desconocida, se ha propuesto la existencia de una respuesta inflamatoria anormal contra la microflora entérica en un huésped susceptible genéticamente como una de ellas (1). Esta hipótesis del desorden genético se apoya en el agrupamiento familiar que existe en la enfermedad y los estudios en gemelos, especialmente en la enfermedad de Crohn (CD) (2). La búsqueda de genes de susceptibilidad para la IBD ha hecho que se identificaran muchos locus para la enfermedad de Crohn y colitis ulcerosa, en concreto un locus de susceptibilidad para la enfermedad de Crohn en la región pericentromérica del cromosoma 16 (IBD1) por Hugot y cols. en 1996 y otros grupos en diferentes países (3-8).Recientemente Hugot y cols. y Ogura y cols., utilizando diferentes procedimientos y basándose en la existencia de este gen de susceptibilidad que se superpone con el IBD1 en el cromosoma 16q12 identificaron el primer gen de susceptibilidad para la enfermedad de Crohn, el NOD2 ( 3 , 9 ) .La inserción de mutaciones en el gen NOD2 es lo que confiere el incremento de la susceptibilidad a la enfermedad de Crohn pero no a la colitis ulcerosa (10). Así, dada la localización genómica y el papel de las proteínas del Nod en el reconocimiento de los lipopolisacáridos bacterianos (LPS) se ha propuesto al NOD2 como un gen de susceptibilidad para la enfermedad de Crohn y además se le atribuye un papel en el sistema inmune innato (3,9,11). En el número de noviembre de 2001 de esta revista ya tuvimos la oportunidad de discutir la importancia de la inmunidad innata en la regulación de la respuesta inmune y también revisamos el papel desempeñado por el NOD2 o CARD15, en el cambio del enfoque de la investigación dentro de la enfermedad de Crohn hacia el estudio de la inmunidad innata en lugar del sistema inmune adquirido (12). Este importante descubrimiento, el primer gen de susceptibilidad para la enfermedad de Crohn, ha mostrado la existencia de un modelo molecular para entender un mecanismo patogénico en la enfermedad de Crohn (3) (AU)

RESUMO

AIM:To determine the tumor necrosis factor alpha (TNF-alpha), interleukin 6 (IL-6) and soluble interleukin 2 receptor (sIL-2r) from peripheral blood mononuclear cells (PBMC) in 25 Chinese patients with ulcerative colitis and 20 healthy controls.METHODS:PBMC were isolated by density gradient centrifugation of heparinized blood and cultures for 24 or 48 hours by stimulation with LPS or PHA. TNF-alphaand sIL-2r were measured by ELISA method and IL-6 measured by biossay.RESULTS:TNF-alphaproduction stimulated by LPS and sIL-2r production by PHA in ulcerative colitis were significantly lower than in healthy controls (TNF-alpha509(46-7244)ng/L vs 1995(117-18 950)ng/L, P < 0.05; sIL-2r 320U/mlplus minus 165U/ml vs 451U/mlplus minus 247U/ml, P < 0.05).Spontaneous TNF-alphaand sIL-2r production were not significantly different between ulcerative colitis and controls (TNF-alpha304(46-7044)ng/L vs 215(46-4009)ng/L,P > 0.05; sIL-2r 264U/mlplus minus 115U/ml vs 236U/mlplus minus139U/ml, P>0.05). IL-6 production by spontaneous release from PBMC in ulcerative colitis group was 109U/mlplus minus 94U/ml vs 44U/mlplus minus 39U/ml for those in healthy controls, P < 0.01. IL-6 stimulated by LPS in ulcerative colitis group was (261U/ml plus minus 80U/ml) higher than in healthy controls (102U/mlplus minus 54U/ml, P < 0.01). No correlation of TNF-alpha, IL-6, sIL-2r production was found to disease activity, disease location and medication.CONCLUSION:Cytokine production from PBMC was also disturbed in Chinese patients with ulcerative colitis.
