Comparing the Continuous Geboes Score With the Robarts Histopathology Index: Definitions of Histological Remission and Response and their Relation to Faecal Calprotectin Levels.

Background And Aims: The histological status of ulcerative colitis [UC] patients in clinical and endoscopic remission has gained space as an important prognostic marker and a key component of disease monitoring. Our main aims were to compare two histological indexes-the continuous Geboes score [GS] and the Robarts Histopathology index [RHI]-regarding their definitions of histological remission and response, and the ability of faecal calprotectin [FC] levels to discriminate between these statuses.

Methods: This was an analysis of three prospective cohorts including 422 patients previously enrolled in other studies.

Comparison of different histological indexes in the assessment of UC activity and their accuracy regarding endoscopic outcomes and faecal calprotectin levels.

Objective: Histological remission is being increasingly acknowledged as a therapeutic endpoint in patients with UC. The work hereafter described aimed to evaluate the concordance between three histological classification systems-Geboes Score (GS), Nancy Index (NI) and RobartsHistopathologyIndex (RHI), as well as to evaluate their association with the endoscopic outcomes and the faecal calprotectin (FC) levels.

Design: Biopsy samples from 377 patients with UC were blindly evaluated using GS, NI and RHI.

Accuracy of Faecal Calprotectin and Neutrophil Gelatinase B-associated Lipocalin in Evaluating Subclinical Inflammation in UlceRaTIVE Colitis-the ACERTIVE study.

Background And Aims: Mucosal healing and histological remission are different targets for patients with ulcerative colitis, but both rely on an invasive endoscopic procedure. This study aimed to assess faecal calprotectin and neutrophil gelatinase B-associated lipocalin as biomarkers for disease activity in asymptomatic ulcerative colitis patients.

Methods: This was a multicentric cross-sectional study including 371 patients, who were classified according to their endoscopic and histological scores.

Hepatic Actinomycosis.

Actinomycosis is a rare disorder caused by an anaerobic gram-positive bacillus (), predominantly by the species. Only 20% of cases show an abdominal manifestation, the appendix and ileocecal valve being the most frequent locations. Definitive diagnosis is based on microbiological cultures, microscopy or macroscopy examination.
