| 1 | Classification of submucosal tumors in the gastrointestinal tract显示文摘This review is part two of three, which will present an update on the classification of gastrointestinal submucosal tumors. Part one treats of the diagnosis and part three of the therapeutic methods regarding gastrointestinal submucosal tumors. In the past there has been some confusion as to the classification of gastrointestinal submucosal tumors. Changes in classifications have emerged due to recent advances in mainly immunohistochemistry and electron microscopy. The aim of this paper is to update the reader on the current classification. Literature searches were performed to find information related to classification of gastrointestinal submucosal tumors. Based on these searches the twelve most frequent submucosal tumor types were chosen for description of their classification. The factors that indicate whether tumors are benign or malignant are mainly size and number of mitotic counts. Gastrointestinal stromal tumors are defined mainly by their CD117 positivity. In the future, there should be no more confusion between gastrointestinal stromal tumors and other types of submucosal tumors.2007 The WJG Press.

| 2 | Vitamin D and autoimmune thyroid diseases显示文摘The role of vitamin D as an immune modulator has been emphasized in recent years,and low levels of the hormone were observed in several autoimmune diseases including multiple sclerosis and systemic lupus erythematosus.Vitamin D mediates its effect though binding to vitamin D receptor(VDR),and activation of VDR-responsive genes.While VDR gene polymorphism was found to associate with autoimmune thyroid diseases(AITDs),few studies examined levels of vitamin D in these patients and those that did yielded conflicting results.We therefore undertook to evaluate the levels of vitamin D in patients with AITDs compared to patients with non-AITDs and healthy controls.Serum vitamin D(25-OH)levels were measured in 50 patients with AITDs,42 patients with non-AITDs and 98 healthy subjects,utilizing the LIAISON chemiluminescence immunoassay(DiaSorin,Saluggia,Italy).VitaminD deficiency was designated at levels lower than 10 ng/ml.Antithyroid antibodies,thyroid functions and demographic parameters were evaluated in all patients.The prevalence of vitamin D deficiency was significantly higher in patients with AITDs compared with healthy individuals(72% versus 30.6%;P<0.001),as well as in patients with Hashimoto’s thyroiditis compared to patients with non-AITDs(79% versus 52%;P<0.05).Vitamin D deficiency also correlated to the presence of antithyroid antibodies(P=0.01)and abnormal thyroid function tests(P=0.059).Significantly low levels of vitamin D were documented in patients with AITDs that were related to the presence of anti thyroid antibodies and abnormal thyroid function tests,suggesting the involvement of vitamin D in the pathogenesis of AITDs and the advisability of supplementation. | Shaye Kivity Nancy Agmon-Levin Michael Zisappl Yinon Shapira Endre V Nagy Katalin Danko Zoltan Szekanecz Pnina Langevitz Yehuda Shoenfeld | 2011 | Cellular & Molecular Immunology2011，8，3： | 47 |
| 3 | Clinical importance of aspirin and clopidogrel resistance显示文摘Aspirin and clopidogrel are important components of medical therapy for patients with acute coronary syndromes, for those who received coronary artery stents and in the secondary prevention of ischaemic stroke. Despite their use, a significant number of patients experience recurrent adverse ischaemic events. Interindividual variability of platelet aggregation in response to these antiplatelet agents may be an explanation for some of these recurrent events, and small trials have linked 'aspirin and/or clopidogrel resistance', as measured by platelet function tests, to adverse events. We systematically reviewed all available evidence on the prevalence of aspirin/clopidogrel resistance, their possible risk factors and their association with clinical outcomes. We also identified articles showing possible treatments. After analyzing the data on different laboratory methods, we found that aspirin/clopidogrel resistance seems to be associated with poor clinical outcomes and there is currently no standardized or widely accepted definition of clopidogrel resistance. Therefore, we conclude that specific treatment recommendations are not established for patients who exhibit high platelet reactivity during aspirin/clopidogrel therapy or who have poor platelet inhibition by clopidogrel. | Gergely Feher Andrea Feher Gabriella Pusch Katalin Koltai Antal Tibold Beata Gasztonyi Elod Papp Laszlo Szapary Gabor Kesmarky Kalman Toth | 2010 | World Journal of Cardiology2010，2，7： | 36 |
| 4 | Diagnostic procedures for submucosal tumors in the gastrointestinal tract显示文摘This review is part one of three, which will present an update on diagnostic procedures for gastrointestinal (GI) submucosal tumors (SMTs). Part two identifies the classification and part three the therapeutic methods regarding GI SMTs. Submucosal tumors are typically asymptomatic and therefore encountered incidentally. Advances in diagnostic tools for gastrointestinal submucosal tumors have emerged over the past decade. The aim of this paper is to provide the readers with guidelines for the use of diagnostic procedures, when a submucosal tumor is suspected. Literature searches were performed to find information on diagnostics for gastrointestinal submucosal tumors. Based on the searches, the optimal diagnostic procedures and specific features of the submucosal tumors could be outlined. Standard endoscppy, capsule endoscopy and push-and-pull enteroscopy (PPE) together with barium contrast X-ray do not alone provide sufficient information, when examining submucosal tumors. Endoscopic ultrasound (EUS), computed tomography (CT), magnetic resonance imaging (MRI) and fluorodeoxyglucose-labeled positron emission tomography (FDG-PET) are recommended as supplementary tools. | Laura Graves Ponsaing Katalin Kiss Annika Loft Lise Ingemann Jensen Mark Berner Hansen | 2007 | World Journal of Gastroenterology2007，13，24： | 25 |
| 5 | Changes in lipid metabolism in chronic hepatitis C显示文摘AIM: To investigate the relationship between certain biochemical parameters of lipid metabolism in the serum and steatosis in the liver.METHODS: The grade of steatosis (0-3) and histological activity index (HAI, 0-18) in liver biopsy specimens were correlated with serum alanine aminotransferase (ALT), total cholesterol and triglyceride levels in 142 patients with chronic hepatitis C (CH-C), and 28 patients with non-alcoholic fatty liver disease (NAFLD) without hepatitis C virus (HCV) infection. The serum parameters were further correlated with 1 797 age and sex matched control patients without any liver diseases.RESULTS: Steatosis was detected in 90 out of 142 specimens (63%) with CH-C. The ALT levels correlated with the grade of steatosis, both in patients with CH-C and NAFLD (P<0.01). Inserting the score values of steatosis as part of the HAI, correlation with the ALT level (P<0.00001) was found. The triglyceride and cholesterol levels were significantly lower in patients with CH-C (with and without steatosis), compared to the NAFLD group and to the virus-free control groups.CONCLUSION: Our study confirms the importance of liver steatosis in CH-C which correlates with lower lipid levels in the sera. Inclusion of the score of steatosis into HAI, in case of CH-C might reflect the alterations in the liver tissue more precisely, while correlating with the ALT enzyme elevation. | Katalin Jármay Gizella Karácsony András Nagy Zsuzsa Schaff | 2005 | World Journal of Gastroenterology2005，11，41： | 22 |
| 6 | Interleukins and interleukin receptors in rheumatoid arthritis: Research, diagnostics and clinical implications显示文摘Rheumatoid arthritis(RA) is an autoimmune disease, resulting in a chronic, systemic inflammatory disorder. It may affect many tissues and organs, but it primarily affects the flexible joints. In clinical practice patient care generates many questions about diagnosis, prognosis, and treatment. It is challenging for health care specialists to keep up to date with the medical literature. This review summarizes the pathogenesis, the polymorphisms of interleukin and interleukin genes and the standard available and possible future immunologictargets for RA treatment. The identification of diseaseassociated interleukin and interleukin receptor genes can provide precious insight into the genetic variations prior to disease onset in order to identify the pathways important for RA pathogenesis. The knowledge of the complex genetic background may prove useful for developing novel therapies and making personalized medicine based on the individual's genetics. | Lili Magyari Dalma Varszegi Erzsebet Kovesdi Patricia Sarlos Bernadett Farago Andras Javorhazy Katalin Sumegi Zsolt Banfai Bela Melegh | 2014 | World Journal of Orthopedics2014，5，4： | 17 |
| 7 | A nuclear import inhibitory peptide ameliorates the severity of cholecystokinin-induced acute pancreatitis显示文摘AIM: To assess the effect of our novel cell-permeable nuclear factor-kappaB (NF-κB) inhibitor peptide PN50 in an experimental model of acute pancreatitis. PN50 was produced by conjugating the cell-penetrating penetratin peptide with the nuclear localization signal of the NF-κB p50 subunit.METHODS: Pancreatitis was induced in male Wistar rats by administering 2×100 μg/kg body weight of cholecystokininoctapeptide (CCK) intraperitoneally (IP) at an interval of 1 h. PN50-treated animals received 1 mg/kg of PN50 IP 30 min before or after the CCK injections. The animals were sacrificed 4 h after the first injection of CCK.RESULTS: All the examined laboratory (the pancreatic weight/body weight ratio, serum amylase activity,pancreatic levels of TNF-α and IL-6, degree of lipid peroxidation, reduced glutathione levels, NF-κB binding activity, pancreatic and lung myeloperoxidase activity) and morphological parameters of the disease were improved before and after treatment with the PN50 peptide.According to the histological findings, PN50 protected the animals against acute pancreatitis by favoring the induction of apoptotic, as opposed to necrotic acinar cell death associated with severe acute pancreatitis.CONCLUSION: Our study implies that reversible inhibitors of stress-responsive transcription factors like NF-κB might be clinically useful for the suppression of the severity of acute pancreatitis. | Tamás Letoha Csaba Somlai Tamáas Takács Annamária Szabolcs Katalin Jármay Zoltán Rakonczay Jr Péter Hegyi Ilona Varga József Kaszaki István Krizbai Imre Boros Ern(?)

| 9 | Body-mass index correlates with severity and mortality in acute pancreatitis: A meta-analysis显示文摘BACKGROUND Obesity rates have increased sharply in recent decades. As there is a growing number of cases in which acute pancreatitis(AP) is accompanied by obesity, we found it clinically relevant to investigate how body-mass index(BMI) affects the outcome of the disease.AIM To quantify the association between subgroups of BMI and the severity and mortality of AP.METHODS A meta-analysis was performed using the Preferred Reporting Items for Systematic Review and Meta-Analysis(PRISMA) Protocols. Three databases(PubMed, EMBASE and the Cochrane Library) were searched for articles containing data on BMI, disease severity and mortality rate for AP. Englishlanguage studies from inception to 19 June 2017 were checked against our predetermined eligibility criteria. The included articles reported all AP cases with no restriction on the etiology of the disease. Only studies that classified AP cases according to the Atlanta Criteria were involved in the severity analyses. Odds ratios(OR) and mean differences(MD) were pooled using the random effects model with the DerSimonian-Laird estimation and displayed on forest plots. The meta-analysis was registered in PROSPERO under number CRD42017077890.RESULTS A total of 19 articles were included in our meta-analysis containing data on 9997 patients. As regards severity, a subgroup analysis showed a direct association between AP severity and BMI. BMI < 18.5 had no significant effect on severity;however, BMI > 25 had an almost three-fold increased risk for severe AP in comparison to normal BMI(OR = 2.87, 95%CI: 1.90-4.35, P < 0.001). Importantly,the mean BMI of patients with severe AP is higher than that of the non-severe group(MD = 1.79, 95%CI: 0.89-2.70, P < 0.001). As regards mortality, death rates among AP patients are the highest in the underweight and obese subgroups. A BMI < 18.5 carries an almost two-fold increase in risk of mortality compared to normal BMI(OR = 1.82, 95%CI: 1.32-2.50, P < 0.001). However, the chance of mortality is almost equal in the normal BMI and BMI 25-30 subgroups. A BMI >30 results in a three times higher risk of mortality in comparison to a BMI < 30(OR = 2.89, 95%CI: 1.10-7.36, P = 0.026).CONCLUSION Our findings confirm that a BMI above 25 increases the risk of severe AP, while a BMI > 30 raises the risk of mortality. A BMI < 18.5 carries an almost two times higher risk of mortality in AP. | Dalma Dobszai Péter Mátrai Zoltan Gyongyi Dezso Csupor Judit Bajor Balint Eross Alexandra Mikó Lajos Szakó Agnes Meczker Roland Hágendorn Katalin Márta Andrea Szentesi Péter Hegyi on behalf of the Hungarian Pancreatic Study Group | 2019 | World Journal of Gastroenterology2019，25，6： | 11 |
| 10 | Restoration of energy level in the early phase of acute pediatric pancreatitis显示文摘Acute pancreatitis (AP) is a serious inflammatory disease with rising incidence both in the adult and pediatric populations. It has been shown that mitochondrial injury and energy depletion are the earliest intracellular events in the early phase of AP. Moreover, it has been revealed that restoration of intracellular ATP level restores cellular functions and defends the cells from death. We have recently shown in a systematic review and meta-analysis that early enteral feeding is beneficial in adults; however, no reviews are available concerning the effect of early enteral feeding in pediatric AP. In this minireview, our aim was to systematically analyse the literature on the treatmentof acute pediatric pancreatitis. The preferred reporting items for systematic review(PRISMA-P) were followed, and the question was drafted based on participants, intervention, comparison and outcomes: P: patients under the age of twenty-one suffering from acute pancreatitis; I: early enteral nutrition (per os and nasogastric- or nasojejunal tube started within 48 h); C: nil per os therapy; O: length of hospitalization, need for treatment at an intensive care unit, development of severe AP, lung injury (including lung oedema and pleural effusion), white blood cell count and pain score on admission. Altogether, 632 articles (Pub Med: 131; EMBASE: 501) were found. After detailed screening of eligible papers, five of them met inclusion criteria. Only retrospective clinical trials were available. Due to insufficient information from the authors, it was only possible to address length of hospitalization as an outcome of the study. Our mini-meta-analysis showed that early enteral nutrition significantly(SD = 0.806, P = 0.034) decreases length of hospitalization compared with nil per os diet in acute pediatric pancreatitis. In this minireview, we clearly show that early enteral nutrition, started within 24-48 h, is beneficial in acute pediatric pancreatitis. Prospective studies and better presentation of research are crucially needed to achieve a higher level of evidence. | Dóra Mosztbacher Nelli Farkas Margit Solymár Gabriella Pár Judit Bajor ákos Szucs József Czimmer Katalin Márta Alexandra Mikó Zoltán Rumbus Péter Varjú Péter Hegyi Andrea Párniczky | 2017 | World Journal of Gastroenterology2017，23，6： | 8 |
| 11 | Interleukin and interleukin receptor gene polymorphisms in inflammatory bowel diseases susceptibility显示文摘Inflammatory bowel disease(IBD),which includes Crohn’s disease(CD)and ulcerative colitis(UC),represents a group of chronic inflammatory disorders caused by dysregulated immune responses in genetically predisposed individuals.Genetic markers are associated with disease phenotype and long-term evolution,but their value in everyday clinical practice is limited at the moment.IBD has a clear immunological background and interleukins play key role in the process.Almost130 original papers were revised including meta-analysis.It is clear these data are very important for understanding the base of the disease,especially in terms of clinical utility and validity,but text often do not available for the doctors use these in the clinical practice nowadays.We conducted a systematic review of the current literature on interleukin and interleukin receptor gene polymorphisms associated with IBD,performing an electronic search of PubMed Database from publications of the last 10 years,and used the following medical subject heading terms and/or text words:IBD,CD,UC,interleukins and polymorphisms. | Lili Magyari Erzsebet Kovesdi Patricia Sarlos Andras Javorhazy Katalin Sumegi Bela Melegh | 2014 | World Journal of Gastroenterology2014，20，12： | 8 |
| 12 | Aging related methylation influences the gene expression of key control genes in colorectal cancer and adenoma显示文摘AIM To analyze colorectal carcinogenesis and age-related DNA methylation alterations of gene sequences associated with epigenetic clock CpG sites. METHODS In silico DNA methylation analysis of 353 epigenetic clock Cp G sites published by Steve Horvath was performed using methylation array data for a set of 123 colonic tissue samples [64 colorectal cancer(CRC), 42 adenoma, 17 normal; GEO accession number: GSE48684]. Among the differentially methylated agerelated genes, secreted frizzled related protein 1(SFRP1) promoter methylation was further investigated in colonic tissue from 8 healthy adults, 19 normal children, 20 adenoma and 8 CRC patients using bisulfite-specific PCR followed by methylation-specific high resolution melting(MS-HRM) analysis. m RNA expression of age-related 'epigenetic clock' genes was studied using Affymetrix HGU133 Plus2.0 whole transcriptome data of 153 colonic biopsy samples(49 healthy adult, 49 adenoma, 49 CRC, 6 healthy children)(GEO accession numbers: GSE37364, GSE10714, GSE4183, GSE37267). Whole promoter methylation analysis of genes showing inverse DNA methylationgene expression data was performed on 30 colonic samples using methyl capture sequencing.RESULTS Fifty-seven age-related Cp G sites including hypermethylated PPP1R16 B, SFRP1, SYNE1 and hypomethylated MGP, PIPOX were differentially methylated between CRC and normal tissues(P < 0.05, ?β≥ 10%). In the adenoma vs normal comparison, 70 CpG sites differed significantly, including hypermethylated DKK3, SDC2, SFRP1, SYNE1 and hypomethylated CEMIP, SPATA18(P < 0.05, ?β≥ 10%). In MS-HRM analysis, the SFRP1 promoter region was significantly hypermethylated in CRC(55.0% ± 8.4 %) and adenoma tissue samples(49.9% ± 18.1%) compared to normal adult(5.2% ± 2.7%) and young(2.2% ± 0.7%) colonic tissue(P < 0.0001). DNA methylation of SFRP1 promoter was slightly, but significantly increased in healthy adults compared to normal young samples(P < 0.02). This correlated with significantly increased SFRP1 m RNA levels in children compared to normal adult samples(P < 0.05). In CRC tissue the mR NA expression of 117 agerelated genes were changed, while in adenoma samples 102 genes showed differential expression compared with normal colonic tissue(P < 0.05, logF C > 0.5). The change of expression for several genes including SYNE1, CLEC3 B, LTBP3 and SFRP1, followed the same pattern in aging and carcinogenesis, though not for all genes(e.g., MGP). CONCLUSION Several age-related DNA methylation alterations can be observed during CRC development and progression affecting the m RNA expression of certain CRC- and adenoma-related key control genes. | Orsolya Galamb Alexandra Kalmár Barbara Kinga Barták árpád V Patai Katalin Leiszter Bálint Péterfia Barnabás Wichmann Gábor Valcz Gábor Veres Zsolt Tulassay Béla Molnár | 2016 | World Journal of Gastroenterology2016，22，47： | 7 |
| 13 | Intralesional steroid is beneficial in benign refractory esophageal strictures:A meta-analysis显示文摘AIM To analyze the effect of intralesional steroid injections in addition to endoscopic dilation of benign refractory esophageal strictures.METHODS A comprehensive search was performed in three databases from inception to 10 April 2017 to identify trials, comparing the efficacy of endoscopic dilation to dilation combined with intralesional steroid injections. Following the data extraction, meta-analytical calculations were performed on measures of outcome by the randomeffects method of Der Simonian and Laird. Heterogeneity of the studies was tested by Cochrane's Q and I^2 statistics. Risk of quality and bias was assessed by the Newcastle Ottawa Scale and JADAD assessment tools.RESULTS Eleven articles were identified suitable for analyses, involving 343 patients, 235 cases and 229 controls in total. Four studies used crossover design with 121 subjects enrolled. The periodic dilation index(PDI) was comparable in 4 studies, where the pooled result showed a significant improvement of PDI in the steroid group(MD:-1.12 dilation/month, 95% CI:-1.99 to -0.25 P = 0.012; I^2 = 74.4%). The total number of repeat dilations(TNRD) was comparable in 5 studies and showed a non-significant decrease(MD:-1.17, 95%CI:-0.24-0.05, P = 0.057; I^2 = 0), while the dysphagia score(DS) was comparable in 5 studies and did not improve(SMD: 0.35, 95%CI:-0.38, 1.08, P = 0.351; I^2 = 83.98%) after intralesional steroid injection.CONCLUSION Intralesional steroid injection increases the time between endoscopic dilations of benign refractory esophageal strictures. However, its potential role needs further research. | László Szapáry Benedek Tinusz Nelli Farkas Katalin Márta Lajos Szakó Agnes Meczker Roland Hágendorn Judit Bajor Aron Vincze Zoltan Gyongyi Alexandra Mikó Dezso Csupor Péter Hegyi Balint Eross | 2018 | World Journal of Gastroenterology2018，24，21： | 7 |
| 14 | Prevalence of SLC22A4, SLC22A5 and CARD15 gene mutations in Hungarian pediatric patients with Crohn’s disease显示文摘AIM: To investigate the frequency of the common NOD2/CARD15 susceptibility variants and two functional polymorphisms of OCTN cation transporter genes in Hungarian pediatric patients with Crohn’s disease (CD). METHODS: A cohort of 19 unrelated pediatric and 55 unrelated adult patients with Crohn’s disease and 49 healthy controls were studied. Genotyping of the three common CD-associated CARD15 variants (Arg702Trp, Gly908Arg and 1007finsC changes) with the SLC22A4 1672C→T, and SLC22A5 -207G→C mutations was performed by direct sequencing of the specifi c regions of these genes.RESULTS: At least one CARD15 mutation was present in 52.6% of the children and in 34.5% of the adults compared to 14.3% in controls. Surprisingly, strongly different mutation profi le was detected in the pediatric versus adult patients. While the G908R and 1007finsC variants were 18.4% and 21.1% in the pediatric group, they were 1.82% and 11.8% in the adults, and were 1.02% and 3.06% in the controls, respectively. The R702W allele was increased approximately two-fold in the adult subjects, while in the pediatric group it was only approximately 64% of the controls (9.09% in the adults, 2.63% in pediatric patients, and 4.08% in the controls). No accumulation of the OCTN variants was observed in any patient group versus the controls.CONCLUSION: The frequency of the NOD2/CARD15 susceptibility variants in the Hungarian pediatric CD population is high and the profile differs from the adult CD patients, whereas the results for SLC22A4 and SLC22A5 mutation screening do not confirm the assumption that the carriage of these genotypes means an obligatory susceptibility to CD. | Judit Bene Lili Magyari Gábor Talián Katalin Komlósi Beáta Gasztonyi Beáta Tari gnes Várkonyi Gyula Mózsik Béla Melegh | 2006 | World Journal of Gastroenterology2006，12，34： | 6 |
| 15 | Correlation between severity of endoscopic findings and apnea-hypopnea index in patients with gastroesophageal reflux disease and obstructive sleep apnea显示文摘AIM: To assess the relationship between severity of gastroesophageal reflux disease and apnea-hypopnea index (AHI) as an indicator of the severity of obstructive sleep apnea.METHODS: Data of 57 patients with proven obstructive sleep apnea and gastroesophageal reflux disease were analyzed. Patients were divided into two groups according to severity of the sleep apnea: 'mild-moderate' (A)-AHI ≥5-30, n = 27, 'severe' (B)-AHI >30, n = 30. All patients underwent apnea monitoring during the night, upper panendoscopy and were asked about typical reflux symptoms.RESULTS: All examined patients in both groups showed a significant overweight and there was a positive correlation between body mass index and the degree of sleep apnea (P = 0.0002). The occurence of erosive reflux disease was significantly higher in 'severe' group (P = 0.0001).Using a logistic regression analysis a positive correlation was found between the endoscopic severity of reflux disease and the AHI (P = 0.016). Forty-nine point five percent of the patients experienced the typical symptoms of reflux disease at least three times a week and there was no significant difference between the two groups.CONCLUSION: A positive correlation can be found between the severity of gastroesophageal reflux disease and obstructive sleep apnea. | Pál Demeter Katalin Várdi Visy Pál Magyar | 2005 | World Journal of Gastroenterology2005，11，6： | 6 |
| 16 | Plasma carnitine ester profile in adult celiac disease patients maintained on long-term gluten free diet显示文摘AIM: To determine the fasting plasma carnitine ester in patients with celiac disease.METHODS: We determined the fasting plasma carnitine ester profile using ESI triple quadrupol mass spectrometry in 33 adult patients with biopsy-confirmed maturity onset celiac disease maintained on long term gluten free diet.RESULIS: The level of free camitine did not differ as the celiac disease patients were compared with the healthy controls, whereas the acetylcarnitine level was markedly reduced (4.703 ± 0.205 vs 10.227 ± 0.368 nmol/mL,P<0.01). The level of propionylcarnitine was 61.5%,butyrylcarnitine 56.9%, hexanoylcarnitine 75%,octanoylcarnitine 71.1%, octenoylcarnitine 52.1%,decanoylcarnitine 73.1%, cecenoylcarnitine 58.3%,lauroylcarnitine 61.5%, miristoylcarnitine 66.7%,miristoleylcarnitine 62.5% and oleylcarnitine 81.1%in the celiac disease patients compared to the control values, respectively (P<0.01).CONCLUSION: The marked decrease of circulating acetylcarnitine with 50-80 % decrease of 11 other carnitine esters shows that the carnitine ester metabolism can be influenced even in clinically asymptomatic and well being adult celiac disease patients, and gluten withdrawal alone does not necessarily normalize all elements of the disturbed carnitine homeostasis. | Judit Bene Katalin Komlósi Beáta Gasztonyi Márk Juhász Zsolt Tulassay Béla Melegh | 2005 | World Journal of Gastroenterology2005，11，42： | 5 |
| 17 | New serological markers in pediatric patients with inflammatory bowel disease显示文摘The spectrum of serological markers associated with inflammatory bowel disease(IBD)is rapidly growing.Due to frequently delayed or missed diagnoses,the application of non-invasive diagnostic tests for IBD,as well as differentiation between ulcerative colitis(UC)and Crohn’s disease(CD),would be useful in the pediatric population.In addition,the combination of pancreatic autoantibodies and antibodies against Saccharomyces cerevisiae antibodies/perinuclear cytoplasmic antibody(pANCA)improved the sensitivity of serological markers in pediatric patients with CD and UC.Some studies suggested that age-associated differences in the patterns of antibodies may be present,particularly in the youngest children.In CD,most patients develop stricturing or perforating complications,and a significant numberof patients undergo surgery during the disease course.Based on recent knowledge,serum antibodies are qualitatively and quantitatively associated with complicated CD behavior and CD-related surgery.Pediatric UC is characterized by extensive colitis and a high rate of colectomy.In patients with UC,high levels of antiCBir1 and pANCA are associated with the development of pouchitis after ileal pouch-anal anastomosis.Thus,serologic markers for IBD can be applied to stratify IBD patients into more homogeneous subgroups with respect to disease progression.In conclusion,identification of patients at an increased risk of rapid disease progression is of great interest,as the application of early and more aggressive pharmaceutical intervention could have the potential to alter the natural history of IBD,and reduce complications and hospitalizations. | Márta Kovács Katalin Eszter Müller Mária Papp Péter László Lakatos Mihály Cs?ndes Gábor Veres | 2014 | World Journal of Gastroenterology2014，20，17： | 4 |
| 18 | Relevance of α-defensins(HNP1-3) and defensin β-1 in diabetes显示文摘AIM: To investigate the genetic background of human defensin expression in type 1 and 2 diabetes.METHODS: Associations between DEFA1/DEFA3 gene copy number polymorphism and diabetes as well as between the promoter polymorphisms of DEFB1 and diabetes were studied. The copy number variation of the DEFA1/DEFA3 genes was determined in 257 diabetic patients(117 patients with type 1 and 140 with type 2 diabetes). The control group consisted of 221 age- and gender-matched healthy blood donors. The cumulative copy numbers of the DEFA1/DEFA3 genes were detected by using quantitative PCR analysis. To evaluate the HNP 1-3(human neutrophil peptide 1-3 or α-defensin) levels in the circulation, plasma HNP 1-3 concentrations were measured by ELISA. The expression of DEFA1/A3 in peripheral leukocytes of the diabetic patients was measured by quantitative RT PCR analysis. Three SNPs of the human DEFB1(human defensin β-1) gene: DEFB1 G-20A(rs11362), DEFB1 C-44G(rs1800972) and DEFB1 G-52A(rs1799946) were genotyped by Custom TaqMan? Real Time PCR assay.RESULTS: Significant differences were observed in HNP1-3 levels between the healthy subjects and both groups of diabetic patients. The mean ± SE was 28.78 ± 4.2 ng/mL in type 1 diabetes, and 29.82 ± 5.36 ng/mL in type 2 diabetes, vs 11.94 ± 2.96 ng/mL in controls; P < 0.01 respectively. There was no significant difference between patients with type 1 and type 2 diabetes in the high plasma concentrations of HNP1-3. The highest concentrations of α-defensin were found in diabetic patients with nephropathy(49.4 ± 4.8 ng/mL), neuropathy(38.7 ± 4.8 ng/mL) or cardiovascular complications(45.6 ± 1.45 ng/L). There was no significant difference in the cumulative copy numbers of DEFA1/DEFA3 genes between controls and patients, or between patients with the two types of diabetes. Comparisons of HNP 1-3 plasma level and DEFA1/A3 copy number of the same patient did not reveal significant relationship between defensin-α levels and the gene copy numbers(r2 = 0.01). Similarly, no positive correlation was observed between the copy numbers and the mRNA expression levels of DEFA1/A3. Regarding the C-44G polymorphism of DEFB1, the GG 'protective' genotype was much less frequent(1%-2%) among both groups of patients than among controls(9%).CONCLUSION: Elevated HNP1-3 levels in diabetes are independent of DEFA1/DEFA3 copy numbers, but GG genotype of C-44G SNP in DEFB1 gene may result in decreased defensin β-1 production. | Balázs Csaba Németh Tamás Várkonyi Ferenc Somogyvári Csaba Lengyel Katalin Fehértemplomi Szabolcs Nyiraty Péter Kempler Yvette Mándi | 2014 | World Journal of Gastroenterology2014，20，27： | 4 |
| 19 | Successful use of adalimumab for treating fistulizing Crohn's disease with pyoderma gangrenosum:Two birds with one stone显示文摘Crohn's disease(CD) is a chronic relapsing and remitting autoinflammatory disorder of the gastrointestinal tract that has many intestinal and extraintestinal complications.The purpose of treatment is long-term remission,reduction of complications,and improvement of patients' quality of life.In many cases,this can be quite challenging and it is necessary to have a well thought out management strategy.We present the case of a 38-year-old woman with fistulizing CD that manifested as diffuse abdominal pain and bloody diarrhea accompanied by arthralgia.In addition,there were ulcerative lesions surrounded by cutaneous inflammation and erythema on her extremities,indicative of pyoderma gangrenosum.The patient was treated with high doses of parenteral methylprednisolone without any improvement and was started on adalimumab.A positive response to adalimumab therapy was observed:after 2 mo of therapy,the ulcerative skin lesion healed completely and the enterogastric fistula was closed after 5 mo adalimumab treatment.Adalimumab might be a suitable initial as well as maintenance therapy in patients with complicated CD. | Eva Zold Arpad Nagy Katalin Devenyi Margit Zeher Zsolt Barta | 2009 | World Journal of Gastroenterology2009，15，18： | 4 |
