| 2 | Metabolic changes in the lower esophageal sphincter influencing the result of anti-reflux surgical interventions in chronic gastroesophageal reflux disease显示文摘AIM: With the availability of a minimally invasive approach, anti-reflux surgery has recently experienced a renaissance as a cost-effective alternative to life-long medical treatment in patients with gastroesophageal reflux disease (GERD). We are not aware of the fact whether reflux episodes causing complaints for a long time i.e., at least for one year are associated with metabolic changes in the lower esophageal sphincter, and if so,whether these may influence functional results achieved after anti-reflux surgery.METHODS: Between 1 January 2001 and 31 December 2002 we performed anti-reflux surgery on 79 patients.Muscle samples were taken from the lower esophageal sphincter (LES) in 33 patients during anti-reflux surgery.Inclusion criteria were: LES resting pressure below 10 mmHg and a marked, pH proven acid exposure to the esophagus of at least one year's duration, causing subjective complaints and requiring continuous proton pump inhibitor treatment. Control samples were obtained from muscle tissue in the gastroesophageal junction that had been removed from 17 patients undergoing gastric or esophageal resection. Metabolic and lysosomal enzyme activities and special protein concentrations 16 parameters in total were evaluated in tissue taken from control specimens and tissue taken from patients with GERD. The biochemical parameters of these intra-operative biopsies were used to correlate the results of anti-reflux operations (Visick I and II-III).RESULTS: In the reflux-type muscle, we found a significant increase of the energy-enzyme activities e.g., creatine kinase, lactate dehydrogenase, β-hydroxybutyrate dehydrogenase, and aspartate aminotransaminase-. The concentration of the structural protein S-100 and the myofibrillar protein troponin I were also significantly increased. Among lysosomal enzymes, we found that the activities of cathepsin B, tripeptidyl-peptidase I, dipeptidylpeptidase II, β-hexosaminidase B, β-mannosidase and β-galactosidase were significantly decreased as compared to the control LES muscles. By analyzing the activity values of the 9 patients in Visick groups Ⅱ and Ⅲ at two months post-surgery, we found a significant increase in the activity of the so-called energy-enzyme values and in the concentration of structural and myofibrillar proteins as compared to the rest of the reflux patients.CONCLUSION: Our results call attention to the metabolic changes that occurred in the LES muscles of reflux patients. The developing hypertrophy-like changes of LES muscles may be a reason for complaints after anti-reflux surgery, which consisted mainly of reports of persisting dysphagia. | Aron Altorjay Arpad Juhasz Viola Kellner Gellert Sohar Matyas Fekete Istvan Sonar | 2005 | World Journal of Gastroenterology2005，11，11： | 2 |
| 3 | NKX2-3 and IRGM variants are associated with diseasesu sceptibility to IBD in Eastern European patients显示文摘AIM: To investigate variants of immunity-related GT-Pase family M (IRGM) and NKX2-3 genes and genotype-phenotype in Eastern European patients with inflammatory bowel disease (IBD).METHODS: We analyzed 1707 Hungarian and Czech subjects with Crohn’s disease (CD) (n = 810, age: 37.1 ± 12.6 years, duration: 10.7 ± 8.4 years) and ulcerative colitis (UC) (n = 428, age: 43.7 ± 15.0 years, duration: 12.6 ± 9.9 years), as well as 469 healthy controls. IRGM rs13361189, NKX2-3 rs10883365 and ECM1 rs13294 polymorphisms were tested by LightCy-cler allele discrimination. Detailed clinical phenotypes were determined by reviewing the medical charts. RESULTS: NKX2-3 rs10883365 variant allele was as-sociated with increased risk for CD (P = 0.009, OR = 1.24, 95% CI = 1.06-1.48) and UC (P = 0.001, OR = 1.36, 95% CI = 1.13-1.63), whereas variant IRGM allele increased risk for CD (P = 0.029, OR = 1.36, 95% CI = 1.03-1.79). In contrast, ECM1 rs13294 was not associat-ed with either CD or UC. In CD, the variant IRGM allele was associated with a colon-only location (P = 0.02, OR = 1.62, 95% CI = 1.07-2.44), whereas in UC, the ECM1 variant was associated with cutaneous manifestations (P = 0.002, OR = 3.36, 95% CI = 1.48-7.63). Variant alleles did not predict resistance to steroids or azathio-prine, efficacy of infliximab, or need for surgery. CONCLUSION: NKX2-3 and IRGM are susceptibility locifor IBD in Eastern European patients. Further studies are needed to confirm the reported phenotype-genotype associations. | Nora Meggyesi Lajos S Kiss Magdalena Koszarska Martin Bortlik Dana Duricova Laszlo Lakatos Tamas Molnar Martin Lenicek Libor Vítek Istvan Altorjay Maria Papp Zsolt Tulassay Pal Miheller Janos Papp Attila Tordai Hajnalka Andrikovics Milan Lukas Peter Laszlo Lakatos | 2010 | World Journal of Gastroenterology2010，16，41： | 2 |

| 6 | Significance and prognostic value of lysosomal enzyme activities measured in surgically operated adenocarcinomas of the gastroesophageal junction and squamous cell carcinomas of the lower third of esophagus显示文摘AIM: To establish whether there are fundamental differences in the biochemistries of adenocarcinomas of the gastroesophageal junction (GEJ) and the squamous cell carcinomas of the lower third of the esophagus (LTE).METHODS: Between February 1, 1997 and February 1,2000, we obtained tissue samples at the moment of resection from 54 patients for biochemical analysis. The full set of data could be comprehensively analyzed in 47 of 54 patients' samples (81%). Of these, 29 were adenocarcinomas of the GEJ Siewert type Ⅰ (n = 8), type Ⅱ (n = 12), type Ⅲ (n = 9), and 18 presented as squamous cell carcinomas of the LTE. We evaluated the mean values of 11-lysosomal enzyme and 1-cytosol protease activities of the tumorous and surrounding mucosae as well as their relative activities, measured as the ratio of activity in tumor and normal tissues from the same patient.These data were further analyzed to establish the correlation with tumor localization, TNM stage (lymph-node involvement), histological type (papillary, signet-ring cell,tubular), state of differentiation (good, moderate, poor),and survival (≤24 or ≥24 mo).RESULTS: In adenocarcinomas, the activity of α-mannosidase (AMAN), cathepsin B (CB) and dipeptidyl-peptidase Ⅰ (DPP Ⅰ) increased significantly as compared to the normal gastric mucosa. In squamous cell carcinomas of the esophagus, we also found a significant difference in the activity of cathepsin L and tripeptidyl-peptidase I in addition to these three. There was a statistical correlation of AMAN,CB, and DPP Ⅰ activity between the level of differentiation of adenocarcinomas of the GEJ and lymph node involvement,because tumors with no lymph node metastases histologically confirmed as well-differentiated, showed a significantly lower activity. The differences in CB and DPP Ⅰ activity correlated well with the differences in survival rates, since the CB and DPP Ⅰ values of those who died within 24 mo following surgical intervention were significantly higher than of those who survived for 2 years or more.CONCLUSION: Adenocarcinomas of the GEJ form a homogenous group from a tumor-biochemical aspect,and differ from the biochemical characteristics of squamous cell carcinomas of the LTE on many points.When adenocarcinomas of the GEJs are examined at the preoperative phase, the ratio of the performed AMAN,CB, and DPP Ⅰ enzymatic activity of the tissue sample from the tumor and adjacent intact mucosa within 2 cm of the tumor may have a prognostic value even in the preoperative examination period, and may indicate that ranking of these patients into the neo-adjuvant treatment group should be considered. | Aron Altorjay Balazs Paal Nicolette Sohar Janos Kiss Imre Szanto Istvan Sohar | 2005 | World Journal of Gastroenterology2005，11，37： | 1 |
| 7 | Prevalence, significance and predictive value of antiphospholipid antibodies in Crohn's disease显示文摘AIM: To assess the prevalence and stability of different antiphospholipid antibodies(APLAs) and their association with disease phenotype and progression in inflammatory bowel diseases(IBD) patients.METHODS: About 458 consecutive patients [Crohn's disease(CD): 271 and ulcerative colitis(UC): 187] were enrolled into a follow-up cohort study in a tertiary IBD referral center in Hungary. Detailed clinical phenotypes were determined at enrollment by reviewing the patients' medical charts. Disease activity, medical treatment and data about evolvement of complications or surgical interventions were determined prospectively during the follow-up. Disease course(development f complicated disease phenotype and need for surgery),occurrence of thrombotic events, actual state of diseaseactivity according to clinical, laboratory and endoscopic scores and accurate treatment regime were recorded during the follow-up,(median, 57.4 and 61.6 mo for CD and UC). Sera of IBD patients and 103 healthy controls(HC) were tested on individual anti-β2-Glycoprotein-I(anti-β2-GPI IgA/M/G), anti-cardiolipin(ACA IgA/M/G)and anti-phosphatidylserine/prothrombin(anti-PS/PT IgA/M/G) antibodies and also anti-Saccharomyces cerevisiae antibodies(ASCA IgA/G) by enzyme-linked immunosorbent assay(ELISA). In a subgroup of CD(n = 198) and UC patients(n = 103), obtaining consecutive samples over various arbitrary timepoints during the disease course, we evaluated the intraindividual stability of the APLA status. Additionally,we provide an overview of studies, performed so far, in which significance of APLAs in IBD were assessed.RESULTS: Patients with CD had significantly higher prevalence of both ACA(23.4%) and anti-PS/PT(20.4%) antibodies than UC(4.8%, p < 0.0001 and10.2%, p = 0.004) and HC(2.9%, p < 0.0001 and15.5%, p = NS). No difference was found for the prevalence of anti-β2-GPI between different groups(7.2%-9.7%). In CD, no association was found between APLA and ASCA status of the patients.Occurrence of anti-β2-GPI, ACA and anti-PS/PT was not different between the group of patients with active vs inactive disease state according to appropriate clinical, laboratory and endoscopic scores in CD as well as in UC patients. All subtypes of anti-β2-GPI and ACA IgM status were found to be very stable over time, in contrast ACA IgG and even more ACA IgA status showed significant intraindividual changes.Changes in antibody status were more remarkable in CD than UC(ACA IgA: 49.9% vs 23.3% and ACA IgG:21.2% vs 5.8%). Interestingly, 59.1% and 30.1% of CD patients who received anti-TNF therapy showed significant negative to positive changes in ACA IgA and IgG antibody status respectively. APLA status was not associated with the clinical phenotype at diagnosis or during follow-up, medical therapy, or thrombotic events and it was not associated with the probability of developing complicated disease phenotype or surgery in a Kaplan-Meier analysis.CONCLUSION: The present study demonstrated enhanced formation of APLAs in CD patients. However,presence of different APLAs were not associated with the clinical phenotype or disease course. | Nora Sipeki Laszlo Davida Eszter Palyu Istvan Altorjay Jolan Harsfalvi Peter Antal Szalmas Zoltan Szabo Gabor Veres Zakera Shums Gary L Norman Peter L Lakatos Maria Papp | 2015 | World Journal of Gastroenterology2015，21，22： | 1 |
| 8 | 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 |
