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…

Effect of a Milk-Based Fruit Beverage Enriched with Plant Sterols and/or Galactooligosaccharides in a Murine Chronic Colitis Model

2019

The potential anti-inflammatory effect of plant sterols (PS) enriched milk-based fruit beverages (PS, 1 g/100 mL) (MfB) with/without galactooligosaccharides (GOS, 2 g/100 mL) (MfB-G) in an experimental mice model of chronic ulcerative colitis was evaluated. Beverages were orally administered to mice every day by gavage to achieve PS and GOS doses of 35 and 90 mg/kg, respectively, and experimental colitis was induced by giving mice drinking water ad libitum containing 2% (w/v) dextran sulphate sodium (DSS) for 7 days, alternating with periods without DSS up to the end of the study (56 days). MfB beverage showed significant reduction of symptoms associated to ulcerative colitis and improved t…

HSP10,HSP70 AND HSP90 IMMUNOHISTOCHEMICAL LEVELS CHANGE IN ULCERATIVE COLITIS AFTER THERAPY

2011

Ulcerative colitis (UC) is a form of inflammatory bowel disease (IBD) characterized by damage of large bowel mucosa and frequent extra-intestinal autoimmune comorbidities. The role played in IBD pathogenesis by molecular chaperones known to interact with components of the immune system involved in inflammation is unclear. We previously demonstrated that mucosal Hsp60 decreases in UC patients treated with conventional therapies (mesalazine, probiotics), suggesting that this chaperonin could be a reliable biomarker useful for monitoring response to treatment, and that it might play a role in pathogenesis. In the present work we investigated three other heat shock protein/molecular chaperones:…

Changes in immunohistochemical levels and subcellular localization after therapy and correlation and colocalization with CD68 suggest a pathogenetic …

2011

In an earlier work, the role of heat shock protein (Hsp60) in the pathogenesis of ulcerative colitis (UC) was suggested by its significant increase in the pathological mucosa parallel with an increase in inflammatory cells. More data in this direction are reported in this work. We analyzed by immunohistochemistry biopsies of colon tissue from 2 groups of patients with UC and treated with either 5-aminosalicylic acid (5-ASA) alone or in combination with a probiotic. We looked for inflammatory markers and Hsp60. Both the treatments were effective in reducing symptoms but the group treated with both 5-ASA and probiotics showed better clinical results. Amelioration of symptoms was associated wi…

Toxic megacolon and human Cytomegalovirus in a series of severe ulcerative colitis patients

2015

Abstract Background Human Cytomegalovirus (HCMV) infection has been reported to be a cause of refractory ulcerative colitis (UC). Toxic megacolon (TM) is a rare but severe complication of an acute attack of UC. Objectives Aim of this study is to evaluate in a case-control study the association between HCMV and TM. Study design All patients who were admitted at Medicine Department of V. Cervello Hospital in Palermo (tertiary referral center) for a severe UC flare-up complicated by the onset of TM (diameter of the transverse colon > 6 cm) between January 1990 and November 2011 were identified through the electronic database. A total of 24 consecutive patients (16 male/8 female) with TM were i…

Impact of probiotics on risk factors for cardiovascular diseases. A review.

2014

International audience; Probiotic microorganisms have historically been used to rebalance disturbed intestinal microbiota and to diminish gastrointestinal disorders, such as diarrhea or inflammatory bowel diseases (e.g., Crohn's disease and ulcerative colitis). Recent studies explore the potential for expanded uses of probiotics on medical disorders that increase the risk of developing cardiovascular diseases and diabetes, such as obesity, hypercholesterolemia, arterial hypertension, and metabolic disturbances such as hyperhomocysteinemia and oxidative stress. This review aims at summarizing the proposed molecular and cellular mechanisms involved in probiotic-host interactions and to identi…

RHEUMATIC PATHOLOGIES IN SUBJECTS WITH INFLAMMATORY BOWEL DISEASE

2010

Inflammatory Bowel Disease (IBD) are commonly associated with rheumatic diseases of the joints. Sixty-five patients are selected during a 5-year study period. All Patients were analyzed with clinical, laboratory and radiographic exams. 38 patients had ulcerative colitis (mean age 42.1 years range:19-75) and 27 patients had Crohn's disease (CD) (mean age 37.2 years, range: 17-64 years). Arthritis occurred in 11 patients (17%): 7 with UC (18.4%) and 4 CD (14.8%). The mean age of patients with arthritis was 35 and mean disease duration of pain and limitation symptoms was 28 months. In 9 patients, arthritis appeared after the onset of bowel symptoms with mean duration of 20 months in UC and 24 …
