| 1 | 炎症性肠病与免疫学关系研究进展显示文摘炎症性肠病是一组病因未明的慢性肠道炎症性疾病,其临床症状以腹痛和腹泻为主,病因和发病机制错综复杂,包括多种因素,其中与机体免疫系统关系密切,目前研究发现免疫异常是炎症性肠病发病的重要因素,包括肠道内环境、免疫细胞、人类白细胞抗原、自身抗体、抗Laminaribioside糖抗体(ALCA)和抗Chitobioside IgA糖抗体(ACCA)、细胞因子、黏附分子、一氧化氮和核因子NF-κB等,他们在炎症的起始和持续发展中起重要的作用,本文就免疫因素在炎症性肠病中的作用作一综述. | 施华秀 任建林 董卫国 | 2008 | 世界华人消化杂志2008，16，4： | 4 |
| 2 | Anti-microbial antibodies in celiac disease:Trick or treat?显示文摘AIM:To determine the prevalence of a new set of anti-glycan and anti-outer membrane protein (anti-OMP) antibodies in a Hungarian cohort of adult Celiac disease (CD) patients.METHODS:190 consecutive CD patients [M/F:71/119, age:39.9 (SD:14.1) years], 100 healthy, and 48 gastrointestinal controls were tested for glycan anti-Saccharomyces cerevisiae (gASCA), anti-laminaribioside (ALCA), anti-chitobioside, anti-mannobioside, anti-OMP antibodies and major NOD2/CARD15 mutations. Thirty out of 82 CD patients enrolled at the time of diagnosis were re-evaluated for the same antibodies after longstanding gluten-free diet (GFD).RESULTS: 65.9% of the CD patients were positive for at least one of the tested antibodies at the time of the diagnosis. Except anti-OMP and ALCA, anti-microbial antibodies were exclusively seen in untreated CD; however, the overall sensitivity was low. Any glycan positivity (LR+:3.13;95% CI:2.08-4.73) was associated with an increased likelihood ratio for diagnosing CD. Significant correlation was found between the levels of anti-glycan and anti-endomysial or anti-transglutaminase antibodies. Anti-glycan positivity was lost after longstanding GFD. Anti-glycan antibody titers were associated with symptoms at presentation, but not the presence of NOD2/CARD15 mutations. Patients with severe malabsorption more frequently had multiple antibodies at diagnosis (P=0.019).CONCLUSION: The presence of anti-glycan antibodies in CD seems to be secondary to the impaired small bowel mucosa which can lead to increased antigen presentation. Furthermore, anti-glycan positivity may be considered an additional marker of CD and dietary adherence. | Maria Papp Ildiko Foldi Istvan Altorjay Eszter Palyu Miklos Udvardy Judit Tumpek Sandor Sipka Ilma Rita Korponay-Szabo Eva Nemes Gabor Veres Tamas Dinya Attila Tordai Hajnalka Andrikovics Gary L Norman Peter Laszlo Lakatos | 2009 | World Journal of Gastroenterology2009，15，31： | 0 |
