Elevated serum eotaxin levels in patients with inflammatory bowel disease.

2002

OBJECTIVE: Eotaxin is a recently characterized chemokine with potent and selective chemotactic activity for eosinophils. Previous studies indicating that eosinophils accumulate and become activated in inflammatory bowel disease (IBD) led us to hypothesize that eotaxin is potentially involved in the pathophysiology of IBD and, therefore, that eotaxin would be increased in the serum of patients with IBD. The objective of this study was to test those assumptions. METHODS: We investigated 72 patients with IBD, 35 with ulcerative colitis, and 37 with Crohn’s disease. A total of 27 patients had active and 45 inactive disease; 26 were receiving corticosteroids. Eotaxin serum levels were determined…

P114 A screening tool for the early diagnosis of extraintestinal manifestations in inflammatory bowel disease: the EMAIL questionnaire

2020

Abstract Background Data on prevalence of extraintestinal manifestations (EIMs) in inflammatory bowel disease (IBD) range from 6% up to 47%. Recently, several red flags and questionnaires have been proposed for early diagnosis of articular manifestations. Our aim was to analyse the prevalence of EIMs in a single-centre prospective cohort, using a comprehensive questionnaire developed by our group to detect all EIMs (EMAIL questionnaire). Methods Patients with IBD attending our Clinic from November 2017 to January 2019 were interviewed using a two-part questionnaire, the first part for clinical-demographic data and the second part for EIMs. Patients positive to screening were referred for mu…

Oral manifestations of gastrointestinal disorders

2017

Indexación: Scopus. Backgroud: A considerable number of gastrointestinal disorders (GIDs) of varied nature (inflammatory, infectious, genetic and other etiology) may produce alterations in the hard and soft oral tissues. Among these are Crohn's disease, ulcerative colitis, celiac and gastroesophageal reflux disease. Material and Methods: Article search was done using the National library of medicine (PubMed) database using different search terms and analyzed according to their importance. Results: A large variety of GIDs can give rise to oral lesions, including: RAS like ulceration, mucosal tags, cobblestoning, mucogingivitis, labial and facial swelling, pyostomatitis vegetans, disgeusia an…

Beneficial Effect of Shikonin on Experimental Colitis Induced by Dextran Sulfate Sodium in Balb/C Mice

2012

[EN] The naphthoquinone shikonin, a major component of the root of Lithospermum erythrorhizon, now is studied as an anti-inflammatory agent in the treatment of ulcerative colitis (UC). Acute UC was induced in Balb/C mice by oral administration of 5% dextran sodium sulfate (DSS). The disease activity index was evaluated, and a histologic study was carried out. Orally administered shikonin reduces induced UC in a dose-dependent manner, preventing the shortening of the colorectum and decreasing weight loss by 5% while improving the appearance of feces and preventing bloody stools. The disease activity index score was much lower in shikonin-treated mice than in the colitic group, as well as the…

Polarization-sensitive hyperspectral imaging of human skin: From system design to clinical validation (Conference Presentation)

2020

We present the development and validation of a new approach for quantitative functional imaging of human skin based on the machine learning technique for the analysis of the hyperspectral skin images. The considered skin parameters include blood volume fraction, blood oxygenation, melanin content, and the epidermal layer thickness. Additionally, the degree of residual polarization of the reflected light has been analyzed. The validity of the approach has been confirmed by the initial preclinical tests with the tissue-mimicking phantoms, functional in-vivo skin tests, and pilot clinical study of type II diabetic patients. The proposed technique has great potential to be implemented in clinic…

Estudio de factores asociados con amputación, en pacientes diabéticos con ulceración en pie

2001

Objetivo: Analizar factores asociados con amputación en pacientes diabéticos que presentan úlceras en sus pies, con el fin de identificar sujetos con alto riesgo para amputación. Método: Hemos estudiado 152 diabéticos que acudieron a la Unidad del pie diabético desde enero de 1996 hasta junio de 1998 con úlceraciones en sus pies. En 14 de ellos fue necesaria la amputación. Se excluyeron sujetos con gangrena. Resultados: Los factores asociados con amputación fueron: antecedentes personales de amputación previa (odds ratio 3,7; 1,01-13,7), retinopatía proliferativa, osteomielitis y, de forma independiente, la presencia de vasculopatía (7,1; 1,88-27,2) e infección grave (14,4; 2,92-71,2). Conc…

Gene transfer approaches for the treatment of inflammatory bowel disease.

2003

The pathogenesis of Crohn's disease and ulcerative colitis, the two major forms of inflammatory bowel disease, involves a complex interplay between certain genetic, environmental and immunological factors. Considerable research progress in the last decade defined key inflammatory pathways in the inflamed gut and identified new potential therapeutic targets. Since the current medical treatment with corticosteroids and anti-inflammatory drugs is often associated with undesired side effects and cannot completely cure IBD, these current advances in our understanding of intestinal pathology may now allow the development of new biologic treatment strategies including gene therapy. In this review,…

A NONHEALING ULCER DIAGNOSED AS EXTRAMEDULLARY PLASMOCYTOMA OF THE LIMB EIGHT YEARS AFTER CARDIAC TRANSPLANTATION

1999

A 63-year-old man was hospitalized for a nonhealing ulcer of the left lower leg that appeared 8 years after orthotopic cardiac transplantation under immunosuppressive therapy including cyclosporine. Serum protein electrophoresis, immunofixation, and urinalysis revealed a monoclonal gammopathy IgG kappa. The final diagnosis of an extramedullary plasmocytoma was made by biopsy of the ulcer, which showed formations of plasmablastic cells. We report a rare case of extramedullary plasmocytoma as a posttransplantational malignancy.

Úlcera eosinofílica lingual: un reto diagnóstico de patogénesis controvertida

2013

ResumenLa úlcera eosinofílica, también conocida como granuloma ulcerativo traumático con eosinofilia estromal, es una infrecuente y benigna lesión ulcerativa de la mucosa oral que presenta una evolución persistente, planteando a menudo diferentes diagnósticos clínicos diferenciales. Su diagnóstico se establece solo a partir del estudio histopatológico, si bien su morfología presenta a menudo características que pueden sugerir al patólogo la existencia de un proceso linfoproliferativo, traduciendo una patogénesis lesional controvertida todavía no bien aclarada.Comunicamos una observación clínico-patológica de úlcera eosinofílica afectando a una mujer de 76 años de edad. La lesión, de 2,5cm d…
