| 2 | Analysis of serum antibody profile against H pylori VacA and CagA antigens in Turkish patients with duodenal ulcer显示文摘AIM: To investigate the frequency of seropositivity aga- inst CagA, VacA proteins and to determine their indepen- dent effects on the development of duodenal ulcer (DU) in Turkish patients. METHODS: The study was designed as a prospective one from a tertiary referral hospital. Dyspeptic patients who were referred to our endoscopy unit for upper gas- trointestinal endoscopy between June 2003 and March 2004 and diagnosed to have DU or nonulcer dyspepsia (NUD) were included. Biopsies from the antrum and body of the stomach were taken in order to assess the current H pylori status by histology, rapid urease test and culture. Fasting sera were obtained from all patients and H pylori status of all sera was determined by IgG antibo- dies using an enzyme-linked immunosorbent assay (ELI- SA) kit. All seropositive patients were further analysed using Western blot assays detecting IgG antibodies aga- inst CagA and VacA proteins. The χ2 test was used for statistical comparison of the values and age-sex adjusted multiple regression analysis was used to determine the independent effects of CagA and VacA seropositivities on the development of DU. RESULTS: Sixty-three patients with DU and 62 patients with NUD were eligible for the final analysis. Seropositi- vity for anti-CagA was detected in 51 of 62 (82%), andin 55 of 63 (87%) patients with NUD and DU, respec- tively (p = no significance), and seropositivity for anti- VacA was found in 25 of 62 (40% ) and in 16 of 63 (25%) patients, with NUD and DU, respectively. CONCLUSION: These findings suggest that none of the- se virulence factors is associated with the development of DU in the studied Turkish patients with dyspepsia. | Yusuf Erzin Sibel Altun Ahmet Dobrucali Mustafa Aslan Sibel Erdamar Ahmet Dirican Murat Tuncer Bekir Kocazeybek | 2006 | World Journal of Gastroenterology2006，12，42： | 3 |
| 3 | Isolation and diagnosis of Helicobacter pylori by a new method: Microcapillary culture显示文摘AIM:To investigate the performance of the microcapillary culture method(MCM) in Helicobacter pylori(H.pylori) isolation and diagnosis.METHODS:Microcapillary culture(MC),classical culture(CC),rapid urease(CLO) test,and histopathologic examination(HE) were performed with biopsy samples.Homogenized biopsy samples were loaded into capillary tubes and incubated for 48 h at 37 ℃ without providing a microaerophilic environment.Additionally,three or four loops of the homogenized sample were inoculated in a ready-to-use selective medium(Becton Dickinson,Helicobacter Agar,Modified) specific for the isolation of H.pylori and incubated at 37 ℃ in a microaerophilic atmosphere provided by Campy Gen(Becton Dickinson,Gas Pack).Bacteria reproducing in microcapillary tubes were evaluated in an inverted microscope and also were evaluated after performing a CC with the content.Results obtained by CC,CLO test,and HE were compared with those of MC.The diagnostic performances of the methods used in this study were evaluated for specificity,sensitivity,positive predictive value(PPV),negative predictive value(NPV),and CI.RESULTS:H.pylori was found positive by CLO test +HE and/or CC culture in 26 patient antrum and corpus biopsy samples.In 25(25/26) patient biopsy samples,H.pylori was isolated by MCM,whereas in only 14(14/26) patient biopsy samples,H.pylori was isolatedby CC.CLO test and HE were found positive in 17(17/26) patient biopsy samples.Comparing the results of the isolation of H.pylori by MCM,CC,CLO test,and HE,the sensitivity of the MCM was found as 96%,the specificity as 80%,the PPV as 83%,the NPV as 95%,and the 95%CI as 0.76(χ2 =31.51,P < 0.01) whereas the sensitivity of the CC was found as 54%(χ2 =19.15,P < 0.01),and the sensitivity of the CLO test and HE were found as 65%(χ2 =25.26,P < 0.01).CONCLUSION:This new microcapillary cultivation method for H.pylori has high diagnostic sensitivity compared with CC,HE,and CLO tests. | Adil M Allahverdiyev Melahat Bagirova Reyhan Caliskan Hrisi Bahar Tokman Hayat Aliyeva Gokce Unal Olga Nehir Oztel Emrah Sefik Abamor Hilal Toptas Pelin Yuksel Fatma Kalayci Mustafa Aslan Yusuf Erzin Kadir Bal Bekir S Kocazeybek | 2015 | World Journal of Gastroenterology2015，21，9： | 2 |
| 4 | Familial chylomicronemia syndrome related chronic pancreatitis: a single-center study显示文摘BACKGROUND: Hypertriglyceridemia induces acute recurrent pancreatitis, but its role in the etiology of chronic pancreatitis(CP) is controversial. This study aimed to evaluate the clinical laboratory and radiological findings of 7 patients with CP due to type 1 hyperlipidemia compared to CP patients with other or undefined etiological factors.METHODS: We retrospectively analyzed the clinical, laboratory and radiological findings of 7 CP patients with type 1 hyper lipidemia compared to CP patients without hypertriglyceridemia These 7 patients had multiple episodes of acute pancreatitis and had features of CP on abdominal CT, endoscopic retrograde cholangiopancreatography and/or endoscopic ultrasonography.RESULTS: All CP patients were classified into two groups: a group with type 1 hyperlipidemia (n=7) and a group with other etiologies (n=58). The mean triglyceride level was 2323±894mg/dL in the first group. Age at the diagnosis of CP in the first group was significantly younger than that in the second group(16.5±5.9 vs 48.3±13.5, P<0.001). The number of episodes of acute pancreatitis in the first group was significantly higher than that in the second group (15.0±6.8 vs 4.0±4.6, P=0.011)The number of splenic vein thrombosis in the first group was significantly higher than that in the second group (4/7 vs 9/58P=0.025). Logistic regression analysis found that younger age was an independent predictor of CP due to hypertriglyceridemia(r=0.418, P=0.000).CONCLUSIONS: Type 1 hyperlipidemia appears to be an etiological factor even for a minority of patients with CP. It manifests at a younger age, and the course of the disease might be severe. | Gurhan Sisman Yusuf Erzin Ibrahim Hatemi Erkan Caglar Salih Boga Vikesh Singh Hakan Senturk | 2014 | Hepatobiliary & Pancreatic Diseases International2014，13，2： | 2 |
