1773. Premalignant gastric lesions in patients included in National colorectal cancer screeningBojan Tepeš, Maja Šeruga, Miroslav Vujasinović, Dejan Urlep, Liljana Ljepovic, Nataša Brglez Jurecic, Alenka Forte, Anita Kek-Ljubec, Miha Skvarč, 2018, original scientific article Abstract: Background. Gastric cancer is the fifth most common malignancy in the world with almost one million new cases annually. Helicobacter pylori infection causes 89% of all gastric cancers. Premalignant lesions (atrophy and intestinal metaplasia) develop after several decades of inflammation. Secondary prevention with gastroscopy is possible, but it is costly and has a low compliance rate. Alternative procedures like serology testing for pepsinogen I and II and pepsinogen I/II ratio are available to select patients for surveillance gastroscopies. Patients and methods. In seven outpatient endoscopic units, 288 patients (154 men; 53.5%), average age 60.68 years, tested positive in National colorectal cancer screening programme SVIT, were included in the study. Gastropanel (BioHit, Finland) was used as a serologic biopsy method. Results. We found 24 patients (12 men, mean age 63.7 years) with pepsinogen (pepsinogen I/II < 3 and/or pepsinogen I < 30 %g/L). Premalignant changes were found on gastric biopsies in 21 patients (7.3% incidence). Operative Link on Gastric Intestinal Metaplasia Assessment (OLGIM) % 1 was found in 20 patients; Operative Link for Gastritis Assessment (OLGA) % 1 was found in 19 patients. Combined accuracy for preneoplastic lesions in Gastropanel positive patients was 87.5%. H. pylori seropositivity was found in 219 patients (76%). Only 24% of our population had normal results. Conclusions. Gastropanel test has proven to be a reliable non-invasive test for advanced gastric preneoplastic lesions that can select patients for further gastroscopy. We found high H. pylori seropositivity in older age groups in Slovenia.

1774. Helicobacter pylori treatment results in Slovenia in the period 2013-2015 as a part of European Registry on Helicobacter pylori managementBojan Tepeš, Marko Kastelic, Miroslav Vujasinović, Polona Lampic, Maja Šeruga, Nataša Brglez Jurecic, Olga Perez Nyssen, Maria G. Donday, Colm O'Morain, Francis Megraud, Adrian G. Mcnicholl, Javier P. Gisbert, 2018, original scientific article Abstract: Background. Helicobacter pylori (H. pylori) is the most common chronic bacterial infection in the world affecting over 50% of the world%s population. H. pylori is a grade I carcinogen, responsible for the development of 89 % of noncardia gastric cancers. In the present study we analyzed the data for H. pylori eradication treatments in Slovenia. Patients and methods. Slovenia is a part of the European Registry on Helicobacter pylori Management from the beginning. In seven medical institutions data for H. pylori eradication treatments was collected for 1774 patients from April 16th 2013 to May 15th 2016. For further modified intention to treat (mITT) analysis 1519 patients were eligible and for per protocol (PP) analysis 1346 patients. Results. Patients% dropout was 11.4%. Eradication rate for 7 day triple therapy with proton pump inhibitor (PPI) + Clarithromycin (C) + Amoxicillin (A) was 88.7% PP and 72.0% mITT; for PPI + C + Metronidazole (M) 85.2% PP and 84.4% mITT. Second line 14 day therapy PPI + A + Levofloxacin had 92.3% eradication rate PP and 87.1% mITT. Ten to fourteen day Bismuth quadruple therapy was the therapy in difficult to treat patients. At the end all patients that adhered to prescribed regimens were cured of their H. pylori infection. Conclusions. High dropout rate deserves further analysis. Slovenia is still a country with < 15% H. pylori resistance to clarithromycin, triple therapy with PPI plus two antibiotics reaches PP eradication rate > 85%, but mITT eradication rates are suboptimal.

1775. The impact of outpatient clinical care on the survival and hospitalisation rate in patients with alcoholic liver cirrhosisDejan Majc, Bojan Tepeš, 2018, original scientific article Abstract: Background In the study, we aimed to determine whether regular outpatient controls in patients with alcoholic liver cirrhosis have an impact on their survival and hospitalisation rates. Patients and methods We included patients with liver cirrhosis and regular outpatient controls as a prospective study group and patients with liver cirrhosis who were admitted to hospital only in cases of complications as a retrospective control group. The study was conducted between 2006 and 2011. Results We included 98 patients in the study group and 101 patients in the control group. There were more outpatient controls in the study group than in the control group (5.54 examinations vs. 2.27 examinations, p = 0.000). Patients in the study group had 25 fewer hospitalisations (10.2%; p = 0.612). The median survival rate was 4.6 years in the study group and 2.9 years in the control group (p = 0.021). Patients with Child A classification had an average survival of one year longer in the study group (p = 0.035). No significant difference was found for Child B patients. Patients with Child C classification had longer survival by 1.6 years in the study group (p = 0.006). Alcohol consumption was lower in the study group than in the control group (p = 0.018). Conclusions We confirmed that patients with regular outpatient controls had lower alcohol consumption, a lower hospitalisation rate and significantly prolonged survival time. We confirmed the necessity for the establishment of regular outpatient controls in patients with alcoholic liver cirrhosis.

1777. Dendritic cell profiles in the inflamed colonic mucosa predict the responses to tumor necrosis factor alpha inhibitors in inflammatory bowel diseaseNataša Smrekar, David Drobne, Lojze Šmid, Ivan Ferkolj, Borut Štabuc, Alojz Ihan, Andreja Nataša Kopitar, 2018, original scientific article Abstract: Background Dendritic cells play crucial roles in the control of inflammation and immune tolerance in the gut. We aimed to investigate the effects of tumor necrosis factor alpha (TNFa) inhibitors on intestinal dendritic cells in patients with inflammatory bowel disease and the potential role of intestinal dendritic cells in predicting the response to treatment. Patients and methods Intestinal biopsies were obtained from 30 patients with inflammatory bowel disease before and after treatment with TNFa inhibitors. The proportions of lamina propria dendritic cell phenotypes were analysed using flow cytometry. Disease activity was endoscopically assessed at baseline and after the induction treatment. Results At baseline, the proportion of conventional dendritic cells was higher in the inflamed mucosa (7.8%) compared to the uninflamed mucosa (4.5%) (p = 0.003), and the proportion of CD103+ dendritic cells was lower in the inflamed mucosa (47.1%) versus the uninflamed mucosa (57.3%) (p = 0.03). After 12 weeks of treatment, the proportion of conventional dendritic cells in the inflamed mucosa decreased from 7.8% to 4.5% (p = 0.014), whereas the proportion of CD103+ dendritic cells remained unchanged. Eighteen out of 30 (60%) patients responded to their treatment by week 12. Responders had a significantly higher proportion of conventional dendritic cells (9.16% vs 4.4%, p < 0.01) with higher expression of HLA-DR (median fluorescent intensity [MFI] 12152 vs 8837, p = 0.038) in the inflamed mucosa before treatment compared to nonresponders. Conclusions A proportion of conventional dendritic cells above 7% in the inflamed inflammatory bowel disease mucosa before treatment predicts an endoscopic response to TNFa inhibitors.

1779. Epidemiology of oral mucosal lesions in SloveniaAndrej Kansky, Vojislav Didanovič, Tadej Dovšak, Božana Lončar Brzak, Ivica Pelivan, Diana Terlević Dabić, 2018, original scientific article Abstract: Background Among the diseases of oral mucosa, malignant tumors are the most dangerous, but not the most common lesions that might appear in the oral cavity. Since most of the studies are focused on the detection of cancer in the oral cavity, we were interested in detecting the frequency of benign changes of the oral mucosa in Slovene population. Oral mucosal lesions are important pointer of oral health and quality of life, especially in elderly. The prevalence of oral mucosal lesions, together with information on the risk habits associated with oral health, such as tobacco and alcohol use, can help in planning future oral health studies and screening programs. Patients and methods Survey upon oral mucosal lesions was conducted during the national project for oral cancer screening in spring 2017 in the Slovenia in which more than 50% of dentists participated and 2395 patients (904 men and 1491 women) were included. Results Clinical examination, which was conducted according to the WHO standards revealed that 645 patients (27%) had oral mucosal lesions. The ten most common oral lesions detected were fibroma, gingivitis, Fordyce spots, white coated tongue, cheek biting, linea alba, denture stomatitis, geographic tongue, recurrent aphthous ulcerations and lichen planus. Conclusions Overall, these epidemiological data suggest need for specific health policies for prevention, diagnosis and treatment of oral mucosal lesions.

1780. Dynamic expression of 11 miRNAs in 83 consecutive primary and corresponding recurrent glioblastoma : correlation to treatment, time to recurrence, overall survival and MGMT methylation statusBoštjan Matos, Emanuela Boštjančič, Alenka Matjašič, Mara Popović, Damjan Glavač, 2018, original scientific article Abstract: Background. Glioblastoma (GBM) is the most common and the most malignant glioma subtype. Among numerous genetic alterations, miRNAs contribute to pathogenesis of GBM and it is suggested that also to GBM recurrence and resistance to therapy. Based on publications, we have selected 11 miRNAs and analyzed their expression in GBM. We hypothesized that selected miRNAs are differentially expressed and involved in primary as well as in recurrent GBM, that show significant expressional differences when different treatment options are in question, and that are related to certain patients and tumor characteristics. Patients and methods. Paraffin embedded tissues, obtained from primary and corresponding recurrent tumor from 83 patients with primary GBM were used. Eleven miRNAs ( miR-7, miR-9, miR-15b, miR-21, miR-26b, miR-124a, miR-199a, let-7a, let-7b, let-7d, and let-7f ) were selected for qPCR expression analysis. For patients who received temozolamide (TMZ) as chemotherapeutic drug, O6-methylguanine-DNA methyltransferase (MGMT) methylation status was defined using the methyl-specific PCR. Results. There was a significant change in expression of miR-7, miR-9, miR-21, miR-26b, mirR-124a, miR-199a and let- 7f in recurrent tumor compared to the primary. In recurrent tumor, miR-15b, let-7d and let-7f significantly changed comparing both treatment options. We also observed difference in progression free survival between patients that received radiotherapy and patients that received radiotherapy and chemotherapy, and longer survival for patients who received chemotherapy after second surgery compared to not treated patients. miR-26b showed correlation to progression free survival and let-7f to overall survival. We did not find any expression difference between the tumors with and without methylated MGMT. Conclusions. Our data suggest that analyzed miRNAs may not only contribute to pathogenesis of primary GBM, but also to tumor progression and its recurrence. Moreover, expression of certain miRNAs appears to be therapy- dependent and as such they might serve as additional biomarker for recurrence prediction and potentially predict a therapy-resistance.
