Concurrent autoimmune diseases in patients with autoimmune hepatitis.
2010
Although the pathomechanisms of autoimmune diseases in various organs remain unresolved, an accumulation of autoimmune diseases in individual patients has been observed. An overlap of autoimmune hepatitis (AIH) and primary biliary cirrhosis (PBC) or primary sclerosing cirrhosis has been well documented. However, the overlap of autoimmune diseases other than PBC or PSC has not yet been investigated in a large cohort.The goal of our analysis was to investigate the incidence of concurrent autoimmune diseases in patients with AIH.We analyzed our cohort of 278 patients with AIH for concurrent autoimmune diseases.A total of 111 patients (40%) were diagnosed with additional autoimmune diseases.

Solid cheese consumption: Quantification of oral coating
2011
International audience; Mouth coating, defined as the residual food that sticks to the oral surface after food ingestion, plays an important role in both the delivery of food components and mouth feel and after-feel perceptions. The aim of this work was to adapt a rapid and simple instrumental method to the quantification of food remaining after the in vivo ingestion of a solid food. This method was investigated in 12 non-trained subjects who consumed four melted cheeses differing in terms of their fat and water contents. Mouth coating was determined by fluorescence measurements using curcumin, an oil-soluble dye that had been added to the cheeses during their preparation. The results obtai…
Factors Enhancing Treatment of Hepatitis C Virus-Infected Italian People Who Use Drugs: The CLEO-GRECAS Experience.
2021
INTRODUCTION: We assessed the performance of direct-acting antivirals (DAAs) in hepatitis C virus (HCV)-infected people who use drugs (PWUDs) in terms of sustained virological response (SVR) and adherence rates in comparison to a location-matched cohort of non-PWUD HCV patients. METHODS: All consecutive HCV RNA-positive PWUDs were enrolled between 2015 and 2019. All subjects underwent DAA treatment according to international guidelines and then followed, at least, up to 12 weeks after the end of treatment (SVR12). The SVR and adherence to treatment was compared with that of non-PWUD HCV patients observed at hepatological units of the CLEO platform. Intention-to-treat analysis was performed.…
IRF4 regulates IL-17A promoter activity and controls RORγt-dependent Th17 colitis in vivo
2011
The transcription factor IRF4 is involved in several T-cell-dependent chronic inflammatory diseases. To elucidate the mechanisms for pathological cytokine production in colitis, we addressed the role of the IRF transcription factors in human inflammatory bowel disease (IBD) and experimental colitis.IRF levels and cytokine production in IBD patients were studied as well as the effects of IRF4 deficiency in experimental colitis.In contrast to IRF1, IRF5, and IRF8, IRF4 expression in IBD was augmented in the presence of active inflammation. Furthermore, IRF4 levels significantly correlated with IL-6 and IL-17 mRNA expression and to a lesser extent with IL-22 mRNA expression in IBD. To further …
Intestinal permeability and genetic determinants in patients, first-degree relatives, and controls in a high-incidence area of Crohn's disease in Sou…

1. Am J Gastroenterol. 2005 Dec;100(12):2730-6. Intestinal permeability and genetic determinants in patients, first-degree relatives, and controls in a high-incidence area of Crohn's disease in Southern Italy. Fries W, Renda MC, Lo Presti MA, Raso A, Orlando A, Oliva L, Giofré MR, Maggio A, Mattaliano A, Macaluso A, Cottone M. Dipartimento di Medicina Interna e Terapia Medica, Università di Messina, Messina, Italy. OBJECTIVE: A defect of gastrointestinal barrier function is considered to represent an important step in the pathogenesis of Crohn's disease (CD) but the mechanisms leading to an increased intestinal permeability (IP) are poorly understood. Since IP is influenced by pro-inflammat…
Push-and-Pull Enteroscopy Using the Double-Balloon Technique (Double-Balloon Enteroscopy) for the Diagnosis of Meckel's Diverticulum in Adult Patient…
2006
Meckel's diverticulum (MD) occurs in 2-3% of the population. Although the clinical, histopathologic, and radiologic features of the complications of MD are well known, the diagnosis may be difficult before surgery.Three patients (age 22-34 yr, two women) presenting with gastrointestinal (GI) bleeding of obscure origin underwent multiple endoscopic and radiologic tests including capsule endoscopy and Tc-99m pertechnetate scintigraphy before push-and-pull enteroscopy using a double-balloon technique (double-balloon enteroscopy). Double-balloon enteroscopy was performed in all three patients using oral and anal approaches to evaluate the entire intestine. In one case, MD was detected using the…
Enteroscopy and its relationship to radiological small bowel imaging
2009
The field of radiological small bowel imaging is changing rapidly, as is small bowel enteroscopy. New techniques allow the depiction of intraluminal, mural, and extraintestinal features of various small bowel disorders, such as Crohn disease, small bowel polyposis syndromes, small intestinal malignancies, and celiac disease. For patients requiring repeated small bowel imaging, modalities that do not use ionizing radiation, such as ultrasound or magnetic resonance imaging, should be considered.
Autoimmune hepatitis following Epstein-Barr virus infection
2008
We describe a case of a young man with autoimmune hepatitis (AIH) following Epstein–Barr virus (EBV) infection, in whom a long follow-up showed favourable outcome with complete clinical recovery and failure to relapse after cessation of immunosuppressive therapy. The study underlines the importance of the differential diagnosis between primary EBV associated hepatitis with features of autoimmunity, in which there is a direct pathogenetic role of the virus, and EBV related AIH, in which EBV could act as the trigger of the immune mediated damage with probable differences between the two conditions with regard to the prognosis and the responsiveness to immunosuppressive treatment. The favourab…
Is Epstein-Barr virus infection associated with the pathogenesis of microscopic colitis?
2017
Abstract Background Epstein-Barr virus (EBV) has been associated with inflammation in the colon, particularly in patients with inflammatory bowel disease (IBD). Even if a relevant plasmocytosis, similar to IBD, is present in microscopic colitis (MC), the frequency of EBV infection in this setting is unknown. Objectives We aimed to compare the frequency of colonic EBV infection in patients with MC, ulcerative colitis (UC), and irritable bowel syndrome (IBS). Study design The frequency of colonic EBV infection in biopsies of 30 patients with MC, 30 patients with UC, and 30 controls with IBS was retrospectively assessed. PCR was performed to detect viral EBV DNA in colonic biopsies. In situ hy…
Short-term Effects of the Flavour of Drinks on Ingestive Behaviours in Man
1998
To examine the influence of the oro-sensory properties of different beverages on spontaneous intake of drinks, and the consequence of the volume of fluid ingested on subsequent food intake, 24 subjects (12 men, 12 women), slightly dehydrated, had access ad libitum, during four different experimental sessions in a cross-over design, to one of four commercial beverages without any other drink. The four beverages differed in flavour and caloric content: mineral water; the same mineral water flavoured with orange and unsweetened; the same mineral water flavoured with orange and sweetened with 100 g/l sucrose; or equally sweetened with 50 mg/l aspartame. Ad libitum: lunch was served 15 min after…
