A Critical Regulatory Role of Leucin Zipper Transcription Factor c-Maf in Th1-Mediated Experimental Colitis

2004

Abstract In this study, we investigated the role of c-Maf, a transcription factor known to induce IL-4 production, in inflammatory bowel diseases and experimental colitis. Although Crohn′s disease (CD) is associated with low IL-4 production by T-bet-expressing Th1 cells in the lamina propria, surprisingly a higher expression of c-Maf in these cells was found as compared with control patients. The relevance of this finding was further evaluated in an animal model of CD induced by adoptive transfer of CD4+CD62L+ T cells in RAG-deficient mice. In this Th1-mediated model, an increase of c-Maf-expressing T lymphocytes in the lamina propria over time was observed. Interestingly, adoptive transfer…

Meta-analysis: remission and response from control arms of randomized trials of biological therapies for active luminal Crohn's disease.

2008

1. Aliment Pharmacol Ther. 2008 Jun;27(12):1210-23. Epub 2008 Mar 14. Meta-analysis: remission and response from control arms of randomized trials of biological therapies for active luminal Crohn's disease.

Cervello, Palermo, Italy. fabiotinemd@virgilio.it BACKGROUND: Remission and response are the main outcomes to evaluate the efficacy of new treatments for Crohn's disease (CD). AIM: To explain variation of remission and response rates in active luminal CD. METHODS: We studied control patients from trials of biological therapies through articles retriev…

Expression of host defense scavenger receptors in spondylarthropathy

2001

Objective Reactive arthritis (ReA) is postulated to be caused by a defective host defense against gram-negative bacteria. HLA–B27 could play a role in this process, but does not account for the many HLA–B27 negative patients. The objective of this study was to test the expression of 3 macrophage scavenger receptors (SRs) that are responsible for innate immunity against gram-negative bacteria: SR class A type I (SR-AI), SR-AII, and the macrophage receptor with collagenous structure (MARCO). We postulate that defects in such receptors might also contribute to the host risk factors that increase the predisposition to ReA and perhaps other subtypes of spondylarthropathy (SpA). Methods Periphera…

Cellular and humoral immunity to the 60-kD heat shock protein in inflammatory bowel disease.

1997

Background: Mycobacteria have been considered a possible etiological agent in Crohn’s disease. Since cross-reactivity between epitopes of mycobacterial and self-heat shock protein might represent a potential disease mechanism, we determined the cellular and humoral immune responses to the mycobacterial and the human 60-kD heat shock protein, as well as various control antigens. Methods: We studied samples from 19 patients with Crohn’s disease, 12 patients with ulcerative colitis, and from 19 healthy individuals. T cell responses were studied using a standard proliferation assays to purified recombinant mycobacterial and human 60-kD heat shock protein. Antibody levels were measured by establ…

Metagenomic Analysis of Crohn's Disease Patients Identifies Changes in the Virome and Microbiome Related to Disease Status and Therapy, and Detects P…

2015

Background The aim of this study was to survey the bacterial and viral communities in different types of samples from patients with Crohn's disease (CD) at different stages of the disease to relate their distribution with the origin and progression of this disorder. Methods A total of 42 fecal samples and 15 biopsies from 20 patients with CD and 20 healthy control individuals were collected for bacterial 16S rRNA gene profiling and DNA/RNA virome metagenomic analysis through 454 pyrosequencing. Their composition, abundance, and diversity were analyzed, and comparisons of disease status, patient status, and sample origin were used to determine statistical differences between the groups. Resu…

Prospective multicenter trial of capsule endoscopy in patients with chronic abdominal pain, diarrhea and other signs and symptoms (CEDAP-Plus Study)

2007

Background On the basis of the published data, capsule endoscopy cannot be recommended in patients whose only symptom is chronic abdominal pain. The present study therefore focused on the diagnostic yield of capsule endoscopy in patients with chronic abdominal pain who were also suffering from additional symptoms. Patients and methods A total of 50 patients with chronic abdominal pain, plus other symptoms singly or in combination were enrolled in this prospective multicenter trial. The "plus" symptoms or signs consisted of weight loss (> 10 % of body weight), inflammation shown by laboratory tests, chronic anemia, or suspected mid-gastrointestinal bleeding. Chronic diarrhea was recorded if …

The appropriateness of colonoscopies at a teaching hospital: magnitude, associated factors, and comparison of EPAGE and EPAGE-II criteria.

2011

Background The growing demand for colonoscopies and inappropriate colonoscopies have become a significant problem for health care. Objectives To assess the appropriateness of colonoscopies and to analyze the association with some clinical and organizational factors. To compare the results of the European Panel of Appropriateness of Gastrointestinal Endoscopy (EPAGE) and the EPAGE-II criteria. Design Cross-sectional study. Setting Endoscopy unit of a teaching hospital in Spain. Patients Patients referred for colonoscopy, excluding urgent, therapeutic indications, and poor cleansing. Main Outcome Measurements Appropriateness of colonoscopies according to the EPAGE criteria. Results From 749 c…

Colour doppler-guided haemorrhoidal artery ligation: A possible evolution of transanal haemorrhoidal dearterialisation

2021

Introduction. Haemorrhoids are a very common disease, with a great economic burden. Many treatments have been developed for trying to solve the problem, being the standard not yet found. In 1995, Doppler-guided haemorrhoidal artery ligation was introduced, aiming to reduce postoperative pain and complications. In this work, an evolution of the aforementioned surgical technique was described. Materials and Methods.183 patients treated with standard Doppler-Guided Haemorrhoidal Artery Ligation were statistically compared with 225 patients dealt with Colour Doppler-Guided Haemorrhoidal Artery Ligation. The procedures were performed under local anaesthesia with patients in lithotomy position. A…

Salivary testosterone is related to both handedness and degree of linguistic lateralization in normal women.

2003

The aim of this study was to test the hypothesis that individual differences in testosterone (T) are associated with different patterns of linguistic lateralization and hand preference. Twenty left-handed (LH) and 19 right-handed (RH) women filled in a handedness questionnaire and performed a consonant–vowel dichotic listening test (DL-CV). Salivary T was measured by radioimmunoassay (RIA). LH women showed significantly lower mean salivary T than RH women. T levels were negatively correlated with the absolute value of the DL laterality index. Subjects with right ear advantage (REA) were classified into strongly and weakly lateralized following Wexler et al. method (Brain Lang. 13 (1981) 13)…
