| 1 | Effect of oral erythromycin on gastric and small bowel transit time of capsule endoscopy显示文摘AIM: To determine the effect of oral erythromycin on gastric and small bowel transit time of capsule endoscopy.METHODS: Consecutive patients who underwent capsule endoscopy du ring the 16-mo study period were either given 250 mg oral erythromycin, 1 h prior to swallowing the capsule endoscope or nothing. The gastric and small bowel transit time, and the small bowel image quality were compared.RESULTS: Twenty-four patients received oral erythromycin whereas 14 patients were not given any prokinetic agent.Patients who received erythromycin had a significantly lower gastric transit time than control (16 min vs70 min, P= 0.005),whereas the small bowel transit time was comparable between the two groups (227 min vs183 min, P = 0.18).Incomplete small bowel examination was found in three patients of the control group and in one patient of the erythromycin group. There was no significant difference in the overall quality of small bowel images between the two groups. A marked reduction in gastric transit time was noted in two patients who had repeat capsule endoscopy after oral erythromycin.CONCLUSION: Use of oral erythromycin significantly reduces the gastric transit time of capsule endoscopy. | Wai K Leung Francis KL Chan Sara SL Fung Mei-Yin Wong Joseph JY Sung | 2005 | World Journal of Gastroenterology2005,11,31: | 16 |
| 2 | Portal hemodynamics as predictors of high risk esophageal varices in cirrhotic patients显示文摘AIM: To evaluate portal hypertension parameters in liver cirrhosis patients with and without esophageal varices (EV). METHODS: A cohort of patients with biopsy confirmed liver cirrhosis was investigated endoscopically and with color Doppler ultrasonography as a possible non-invasive predictive tool. The relationship between portal hemodynamics and the presence and size of EV was evaluated using uni-and multivariate approaches. RESULTS: Eighty five consecutive cirrhotic patients (43 men and 42 women) were enrolled. Mean age (± SD) was 47.5 (± 15.9). Portal vein diameter (13.88 ± 2.42 vs 12.00 ± 1.69, P < 0.0005) and liver vascular index (8.31 ± 2.72 vs 17.8 ± 6.28, P < 0.0005) were found to be significantly higher in patients with EV irrespective of size and in patients with large varices (14.54 ± 1.48 vs 13.24 ± 2.55, P < 0.05 and 6.45 ± 2.78 vs 10.96 ± 5.05, P < 0.0005, respectively), while portal vein flow velocity (13.25 ± 3.66 vs 20.25 ± 5.05, P < 0.0005), congestion index (CI) (0.11 ± 0.03 vs 0.06 ± 0.03, P < 0.0005), portal hypertensive index (2.62 ± 0.79 vs 1.33 ± 0.53, P < 0.0005), and hepatic (0.73 ± 0.07 vs 0.66 ± 0.07, P < 0.001) and splenic artery resistance index (RI) (0.73 ± 0.06 vs 0.62 ± 0.08, P < 0.0005) were significantly lower. A logistic regression model confirmed spleen size (P = 0.002, AUC 0.72) and portal hypertensive index (P = 0.040, AUC 0.79) as independent predictors for the occurrence of large esophageal varices (LEV). CONCLUSION: Our data suggest two independent situations for beginning endoscopic evaluation ofcompensated cirrhotic patients: Portal hypertensive index > 2.08 and spleen size > 15.05 cm. These factors may help identifying patients with a low probability of LEV who may not need upper gastrointestinal endoscopy. | Mohammad K Tarzamni Mohammad H Somi Sara Farhang Morteza Jalilvand | 2008 | World Journal of Gastroenterology2008,14,12: | 15 |
| 3 | Endocrine impact of Helicobacter pylori:Focus on ghrelin and ghrelin o-acyltransferase显示文摘Ghrelin is predominantly produced by the gastric enteroendocrine cell compartment and is octanoylated by the recently discovered ghrelin o-acyltransferase (GOAT) before secretion into the bloodstream. This octanoylation is essential for many of the biological properties of ghrelin including appetite stimulation and anti-inflammatory properties as only the acylated form of ghrelin binds to the ghrelin receptor, the growth hormone secretagogue receptor (GHS-R). Given the gastric location of ghrelin production, it is perhaps not surprising that insult to the gastric mucosa affects circulating ghrelin levels in humans. Helicobacter pylori (H. pylori) infects more than f ifty percent of the world's population and once established within the gastric mucosa, can persist for life. Infection is associated with chronic gastritis, gastric atrophy and ulceration, reduced appetite and a lower body mass index (BMI). The large majority of studies investigating levels of circulating ghrelin and ghrelin expression in the stomach in patients with H. pylori infection indicate that the bacterium has a negative impact on ghrelin production and/or secretion. Eradication of infection restores ghrelin, improves appetite and increases BMI in some studies, however, a causative relationship between H. pylori-associated serum ghrelin decline and food intake and obesity has not been established. Most studies measure total ghrelin in the circulation although the measurement of the ratio of acyl/total ghrelin gives a clearer indication that the ghrelin acylation process is altered during infection and atrophy. GOAT is essential for the production of biologically-active, acyl ghrelin and the impact of H. pylori on GOAT expression and activity will be highly informative in the future. | Penny L Jeffery Michael A McGuckin Sara K Linden | 2011 | World Journal of Gastroenterology2011,17,10: | 12 |
| 4 | Effects of resveratrol in experimental and clinical non-alcoholic fatty liver disease显示文摘The prevalence of obesity and related conditions like non-alcoholic fatty liver disease(NAFLD) is increasing worldwide and therapeutic options are limited.Alternative treatment options are therefore intensively sought after.An interesting candidate is the natural polyphenol resveratrol(RSV) that activates adenosinmonophosphate-activated protein kinase(AMPK) and silent information regulation-2 homolog 1(SIRT1).In addition,RSV has known anti-oxidant and anti-inflammatory effects.Here,we review the current evidence for RSVmediated effects on NAFLD and address the different aspects of NAFLD and non-alcoholic steatohepatitis(NASH) pathogenesis with respect to free fatty acid(FFA) flux from adipose tissue,hepatic de novo lipogenesis,inadequate FFA β-oxidation and additional intra- and extrahepatic inflammatory and oxidant hits.We review the in vivo evidence from animal studies and clinical trials.The abundance of animal studies reports a decrease in hepatic triglyceride accumulation,liver weight and a general improvement in histological fatty liver changes,along with a reduction in circulating insulin,glucose and lipid levels.Some studies document AMPK or SIRT1 activation,and modulation of relevant markers of hepatic lipogenesis,inflammation and oxidation status.However,AMPK/SIRT1-independent actions are also likely.Clinical trials are scarce and have primarily been performed with a focus on overweight/obese participants without a focus on NAFLD/NASH and histological liver changes.Future clinical studies with appropriate design are needed to clarify the true impact of RSV treatment in NAFLD/NASH patients. | Sara Heebll Karen Louise Thomsen Steen B Pedersen Hendrik Vilstrup Jacob George Henning Grnbk | 2014 | World Journal of Hepatology2014,6,4: | 11 |
| 5 | Membrane-bound mucins and mucin terminal glycans expression in idiopathic or Helicobacter pylori, NSAID associated peptic ulcers显示文摘AIM:To determine the expression of membrane-bound mucins and glycan side chain sialic acids in Helicobacter pylori(H.pylori)-associated,non-steroidal inflammatory drug(NSAID)-associated and idiopathic-gastric ulcers.METHODS:We studied a cohort of randomly selected patients with H.pylori(group 1,n=30),NSAID(group 2,n=18),combined H.pylori and NSAID associated gastric ulcers(group 3,n=24),and patients with idiopathic gastric ulcers(group 4,n=20).Immunohistochemistry for MUC1,MUC4,MUC17,and staining for Erythrina cristagalli agglutinin and Sambucus nigra agglutinin(SNA)lectins was performed on sections from the ulcer margins.RESULTS:Staining intensity of MUC17 was higher in H.pylori ulcers(group 1)than in idiopathic ulcers(group4),11.05±3.67 vs 6.93±4.00 for foveola cells,and10.29±4.67 vs 8.00±3.48 for gland cells,respectively(P<0.0001).In contrast,MUC1 expression was higher in group 4 compared group 1,9.89±4.17 vs 2.93±5.13 in foveola cells and 7.63±4.60 vs 2.57±4.50 for glands,respectively(P<0.0001).SNA lectin staining was increased in group 4,in parallel to elevated MUC1expression,indicating more abundantα2-6 sialylation in that group.CONCLUSION:Cytoplasmic MUC17 staining was sig-nificantly decreased in the cases with idiopathic ulcer.The opposite was observed for both MUC1 and SNA lectin.This observation may reflect important pathogenic mechanisms,since different mucins with altered sialylation patterns may differ in their protection efficiency against acid and pepsin. | Yaron Niv Doron Boltin Marisa Halpern Miriam Cohen Zohar Levi Alex Vilkin Sara Morgenstern Vahig Manugian Erica St Lawrence Pascal Gagneux Sukhwinder Kaur Poonam Sharma Surinder K Batra Samuel B Ho | 2014 | World Journal of Gastroenterology2014,20,40: | 5 |
| 6 | Annexin A2 as a biomarker for hepatocellular carcinoma in Egyptian patients显示文摘AIM To investigate the clinical utility of serum annexin A2(ANXA2) as a diagnostic marker for early hepatocellular carcinoma(HCC).METHODS This study was performed in HCC Clinic of Ain Shams University Hospitals, Cairo, Egypt and included: Group 1: Fifty patients with early stage HCC(Barcelona Clinic Liver Cancer stage A); Group 2: Twenty five patients with chronic liver disease; and Control Group: Fifteen healthy, age-and sex-matched subjects who were seronegative for viral hepatitis markers. The followinglaboratory investigations were done: Viral hepatitis markers [hepatitis B surface antigen and hepatitis C virus(HCV) antibodies], HCV RNA in HCV antibody-positive patients, serum alpha fetoprotein(AFP), and serum ANXA2 levels.RESULTS In this study, 88% of HCC patients(n = 44) were HCVpositive, while HBV infection represented only 8% of all HCC patients(n = 4); and two patients were negative for both viral markers. A highly significant difference was found between patients with HCC and chronic liver disease as well as controls with regard to serum ANXA2 levels(130, IQR 15-240; 15, IQR 15-17; and 17, IQR 15-30 ng/m L, respectively). The area under the curve of ANXA2 was 0.865; the cut-off value was established to be 18 ng/mL with a diagnostic sensitivity of 74% and a specificity of 88%, while the sensitivity and specificity of AFP at the cut-off value of 200 ng/dL were 20% and 100%, respectively.CONCLUSION Serum ANXA2 may serve as a biomarker for the early detection of HCC. | Mohamed K Shaker Hanzada I Abdel Fattah Ghada S Sabbour Iman F Montasser Sara M Abdelhakam Eman El Hadidy Rehab Yousry Ahmed K El Dorry | 2017 | World Journal of Hepatology2017,9,9: | 4 |
