IL28B polymorphisms influence stage of fibrosis and spontaneous or interferon-induced viral clearance in thalassemia patients with hepatitis C virus infection.
Background. Polymorphisms in the interleukin-28B are important determinants in the spontaneous and drug-induced control of hepatitis C virus infection. Design and Methods. We assessed the association of rs8099917 and rs12979860 polymorphisms with spontaneous viral clearance, severity of liver fibrosis, and response to interferon-monotherapy in 245 Thalassemia Major patients with Hepatitis C Virus infection. Results. Ninety-eight patients (40%) had a spontaneous viral clearance, while 147 patients (60%) developed a chronic infection. Spontaneous viral clearance was more frequent among patients with the T/T genotype of rs8099917 polymorphism (OR 2.130; p=0.008) or C/C genotype of rs12979860 p…
IL-23R determines susceptibility in Crohnʼs disease in a mediterranean area
Cytomegalovirus disappearance after treatment for refractory ulcerative colitis in 2 patients treated with infliximab and 1 patient with leukapheresis
The role of CARD15 mutations and smoking in the course of Crohn's disease in a Mediterranean area.
To evaluate the role of CARD15 mutations and smoking in the main events of Crohn's disease (CD).A total of 182 patients with CD were included in a prospective study in order to evaluate the role of CARD15 mutations and smoking in the main outcomes of disease course: first operation and surgical recurrence. The following variables were evaluated in a univariable and multivariable analysis: age, sex, site of disease, pattern, smoking habit, extraintestinal manifestations, duration of disease, and CARD15 mutation. The Kaplan-Meier method for survival curves and Cox model for multivariable analysis were, respectively, used.A total of 110 patients were operated on and 32 were reoperated on. The …
Intestinal permeability and genetic determinants in patients, first-degree relatives, and controls in a high-incidence area of Crohn's disease in Southern Italy.
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…
P097 NATURAL HISTORY OF CYTOMEGALOVIRUS INFECTION IN A COHORT OF PATIENTS DIAGNOSED WITH MODERATE-SEVERE ULCERATIVE COLITIS
Nonsense-mediated decay mechanism is a possible modifying factor of clinical outcome in nonsense cd39 beta thalassemia genotype
Nonsense-mediated mRNA decay (NMD) is a surveillance system to prevent the synthesis of non-functional proteins. In β-thalassemia, NMD may have a role in clinical outcome. An example of premature translation stop codons appearing for the first time is the β-globin cd39 mutation; when homozygous, this results in a severe phenotype. The aim of this study was to determine whether the homozygous nonsense cd39 may have a milder phenotype in comparison with IVS1,nt110/cd39 genotype. Genotypes have been identified from a cohort of 568 patients affected by β-thalassemia. These genotypes were compared with those found in 577 affected fetuses detected among 2292 prenatal diagnoses. The…
Familial mediterranean fever gene (MEVF) mutations in Crohnʼs disease in a Mediterranean area
In utero fetal liver hematopoietic stem cell transplantation: is there a role for alloreactive T lymphocytes?
The use of hematopoietic stem cells for in utero transplantation to create permanent hematochimerism represents a new concept in fetal therapy, although this approach has provided quite heterogeneous results. Flake and Zanjani have provided an excellent updated review of the current knowledge of in
Incidence of Crohn's disease and CARD15 mutation in a small township in Sicily.
Background: The incidence of Crohn's disease (CD) has been shown to be lower in Southern than in Northern Europe. Data on the frequency of the NOD2/CARD15 mutations for Mediterranean area are very scant. Aim: To determine the incidence of CD from 1979 to 2002 in a township in Sicily together with the allele frequency of NOD2/CARD15 mutations in patients, family members and controls, and to determine the allele frequency of these mutations in sporadic CD from other areas of Sicily in comparison with a control population. Methods: Casteltermini is a small town close to Agrigento (Sicily) with a population of 9,130 inhabitants. All the diagnoses of inflammatory bowel disease (IBD) made from 19…
