Prevalence of virulence-associated genotypes of Helicobacter pylori and correlation with severity of gastric pathology in patients from western Sicil…

2008

In a bacterium like Helicobacter pylori, which is characterized by a recombinant population structure, the associated presence of genes encoding virulence factors might be considered an expression of a selective advantage conferred to strains with certain genotypes and, therefore, a potentially useful tool for predicting the clinical outcome of infections. However, differences in the geographical and ethnic prevalence of the H. pylori virulence-associated genotypes can affect their clinical predictive value and need to be considered in advance. In this study we carried out such an evaluation in a group of patients living in Sicily, the largest and most populous island in the Mediterranean S…

Expansion of intestinal CD4+CD25(high) Treg cells in patients with ankylosing spondylitis: a putative role for interleukin-10 in preventing intestina…

2010

Objective: subclinical gut inflammation has been demonstrated in ankylosing spondylitis (AS) patients. Aim of this study was to determine the frequency of regulatory CD4+CD25high T cells (Treg), and to evaluate Treg-related cytokines (IL-2, TGF-β, IL-10), and transcription factors (FOXP3 and STAT5) in the ileum of AS patients. Methods: Quantitative gene expression analysis, by rt-PCR, of Treg-related cytokines (IL-2, TGF-β, IL-10) and transcription factor (STAT-5 and FOXP3) was performed on ileal biopsies of 18 AS and 15 active Crohn’s disease (CD) patients, and 15 healthy subjects (HS). Tissue and circulating Treg cells were also analyzed by flow cytometry. Results: A significant up-regula…
