چکیده
Background: Several antibodies, also called serological markers, are associated with specifi c forms, disease behavior and phenotype of infl ammatory bowel disease (IBD). Aim: Summarize and analyze the evidence of the utility of serologic markers in IBD, making emphasis on their clinical utility and behavior between populations. Material and methods: Relevant articles were located by computer-assisted search of PubMed (since January 1979 until December 2008). Results: Anti-Saccharomyces cerevisiae antibodies (ASCA) and perinuclear Anti-neutrophil Cytoplasmic Antibodies (pANCA) are the best studied serological markers. Assessing both ASCA and pANCA allows a better differentiation of Crohn’s disease (CD) from ulcerative colitis (UC) than by using the individual tests alone. The ASCA+/pANCAphenotype is characteristic of CD, while the ASCA-/pANCA+ phenotype is found in UC. The interest on atypical ANCA is growing as it may be a useful tool to distinguish between different IBD forms. Newer markers derived from various microbial species of the gut and glycan markers are of interest as they offer new ways to stratify patients into Resumen Antecedentes: Existen anticuerpos, también llamados marcadores serológicos, que se asocian con formas específicas, comportamiento y fenotipo de enfermedad inflamatoria intestinal (EII). Objetivo: Resumir y analizar evidencia sobre la utilidad de marcadores serológicos en EII, haciendo énfasis en utilidad clínica y comportamiento entre poblaciones. Material y métodos: Los artículos relevantes fueron recuperados a través de búsqueda electrónica en PubMed (desde Enero 1979 hasta Diciembre 2008). Resultados: Los anticuerpos anti-Saccharomyces cerevisiae (ASCA) y los anticitoplasma del neutrófilo de patrón perinuclear (p-ANCA) son los marcadores serológicos más estudiados. Se sabe que combinando el resultado de ambos anticuerpos se logra una mejor distinción entre la enfermedad de Crohn (EC) y la colitis ulcerativa (CU) que cuando se analizan aisladamente. El fenotipo ASCA+/pANCAes característico de EC, mientras el ASCA-/pANCA+ de CU. El interés en el patrón atípico de ANCA está aumentando, ya que podría ser una herramienta útil para distinguir entre las formas de EII. Los marcadores derivados de diversas especies microbianas y de polisacáridos fueron Document downloaded from http://www.elsevier.es, day 18/06/2017. This copy is for personal use.

The panel of serologic markers for inflammatory bowel diseases (IBD) is rapidly expanding. Although anti-Saccharomyces cerevisiae antibodies (ASCA) and atypical perinuclear antineutrophil cytoplasmic antibodies (P-ANCA) remain the most widely investigated, an increasing amount of experimental data is available on newly discovered antibodies directed against various microbial antigens. The role ...
متن کاملSerological Markers for Inflammatory Bowel Disease in AIDS Patients with Evidence of Microbial Translocation
BACKGROUND Breakdown of the gut mucosal barrier during chronic HIV infection allows translocation of bacterial products such as lipopolysaccharides (LPS) from the gut into the circulation. Microbial translocation also occurs in inflammatory bowel disease (IBD). IBD serological markers are useful in the diagnosis of IBD and to differentiate between Crohn's disease (CD) and ulcerative colitis (UC...
متن کاملDiagnostic accuracy of fecal calprotectin in assessing the severity of inflammatory bowel disease: From laboratory to clinic
Background: Inflammatory bowel disease (IBD) involves chronic inflammation of the digestive tract. In the past decades, fecal calprotectin has been proposed as a useful biomarker for the differential diagnosis between IBD patients and healthy controls. We designed this study to evaluate the diagnostic ability of fecal calprotectin (FC) and conventional inflammatory markers in IBD patients. M...

Introduction: Inflammatory bowel disease(IBD) is caused by genetic, environmental, microbial and immune factors. IBD has two primary forms: Ulcerative colitis and Crohn´s disease. The incidence of IBD has significantly increased over the last few decades. Given that patients have poor response to drug treatments or are resistant to drug therapies, new therapies are needed for gastrointestinal i...
