A kettős-ballonos endoszkópia szerepe a vékonybél betegségeinek diagnózisában és kezelésében összehasonlítva a kapszulás endoszkópiával

A legutóbbi évekig csak a vékonybél kezdeti szakasza volt megközelíthetô a diagnosztikus vagy terápiás endoszkópos beavatkozások számára. Egy új, kettôs ballonos (DBE) endoszkópos eljárás, amely nagy felbontású képet szolgáltat, mindkettôre lehetôséget nyújt a gastrointestinalis traktus bármely területén. A tanulmány célja az volt, hogy beszámoljunk a Fujinon EN-T5 terápiás kettôs ballonos enteroszkóppal szerzett tapasztalatainkról, illetve összevessük az eredményeket a korábbi kapszulás endoszkópia eredményével, akinél ez rendelkezésre állt

Common NOD2/CARD15 variants are not associated with susceptibility or the clinicopathologic characteristics of sporadic colorectal cancer in Hungarian patients

BACKGROUND: Epidemiological observations suggest that cancer arises from chronically inflamed tissues. Inflammatory bowel disease (IBD) is a typical example as patients with longstanding IBD are at an increased risk for developing colorectal cancer (CRC) and mutations of the NOD2/CARD15 gene increase the risk for Crohn's disease (CD). Recently, NOD2/CARD15 has been associated with a risk for CRC in some studies, which stemmed from ethnically diverse populations. Our aim was to identify common NOD2/CARD15 mutations in Hungarian patients with sporadic CRC. METHODS: A total of 194 sporadic CRC patients (m/f: 108/86, age at diagnosis of CRC: 63.2 ± 9.1 years old) and 200 healthy subjects were included. DNA was screened for SNP8, SNP12 and SNP13 NOD2/CARD15 mutations by denaturing-HPLC and confirmed by direct sequencing. RESULTS: NOD2/CARD15 mutations were found in 28 patients (14.4%) and in 23 controls (11.5%, p = NS). Allele frequencies for SNP8/R702W (1.8% vs. 1.5%) SNP12/G908R (1.8% vs. 1.8%) and SNP13/3020insC (3.6% vs. 2.5%) were also not statistically different between patients and controls. The clinicopathologic characteristics of CRC patients with or without NOD2/CARD15 mutations were not significantly different. CONCLUSION: Our results suggest that common NOD2/CARD15 mutations alone do not contribute to CRC risk in the Hungarian population

Perianal disease, small bowel disease, smoking, prior steroid or early azathioprine/biological therapy are predictors of disease behavior change in patients with Crohn’s disease

AIM: To assess the combined effect of disease phenotype, smoking and medical therapy [steroid, azathioprine (AZA), AZA/biological therapy] on the probability of disease behavior change in a Caucasian cohort of patients with Crohn’s disease (CD)
