Abstract
BACKGROUND & AIMS Autoimmune pancreatitis (AIP) is an immune-mediated disease of the pancreas with distinct pathophysiology and manifestations. Our aims were to characterize type 1 AIP in a large pan-European cohort and study the effectiveness of current treatment regimens. METHODS We retrospectively analyzed adults diagnosed since 2005 with type 1 or not-otherwise-specified AIP in 42 European university hospitals. Type 1 AIP was uniformly diagnosed using specific diagnostic criteria. Patients with type 2 AIP and those who had undergone pancreatic surgery were excluded. The primary end point was complete remission, defined as the absence of clinical symptoms and resolution of the index radiologic pancreatic abnormalities attributed to AIP. RESULTS We included 735 individuals with AIP (69% male; median age, 57 years; 85% White). Steroid treatment was started in 634 patients, of whom 9 (1%) were lost to follow-up. The remaining 625 had a 79% (496/625) complete, 18% (111/625) partial, and 97% (607/625) cumulative remission rate, whereas 3% (18/625) did not achieve remission. No treatment was given in 95 patients, who had a 61% complete (58/95), 19% partial (18/95), and 80% cumulative (76/95) spontaneous remission rate. Higher (≥0.4 mg/kg/day) corticosteroid doses were no more effective than lower (<0.4 mg/kg/day) doses (odds ratio, 0.428; 95% confidence interval, 0.054-3.387) and neither was a starting dose duration >2 weeks (odds ratio, 0.908; 95% confidence interval, 0.818-1.009). Elevated IgG4 levels were independently associated with a decreased chance of complete remission (odds ratio, 0.639; 95% confidence interval, 0.427-0.955). Relapse occurred in 30% of patients. Relapses within 6 months of remission induction were independent of the steroid-tapering duration, induction treatment duration, and total cumulative dose. CONCLUSIONS Patients with type 1 AIP and elevated IgG4 level may need closer monitoring. For remission induction, a starting dose of 0.4 mg/kg/day for 2 weeks followed by a short taper period seems effective. This study provides no evidence to support more aggressive regimens.

Abstract
Crohn's disease is an inflammatory, autoimmune disorder that predominantly affects the intestines but can also affect extraintestinal organs. Certain neurological conditions, such as autoimmune encephalitis, can develop along with this disease. In this case report, we present a case of anti-glutamic acid decarboxylase (GAD) antibody-associated autoimmune encephalitis that occurred shortly after the diagnosis of Crohn's disease and was unrelated to the treatment and nutritional deficiencies. After a significant weight loss (24 kg) and persistent diarrhea, the patient was diagnosed with Crohn's disease by colonoscopy and biopsy. Within two weeks after the diagnosis, he experienced altered consciousness and memory impairment, followed by a rapid deterioration in consciousness and respiratory distress, leading to intubation and admission to the intensive care unit. His brain MRI revealed asymmetrical diffuse cortical diffusion restrictions, hyperintense signals on fluid-attenuated inversion recovery (FLAIR) sequences, and diffuse pachymeningeal contrast enhancement involving both cingulate gyri, bilateral insular cortices, amygdalae, hippocampi, and the right precuneus. Analysis of cerebrospinal fluid (CSF) revealed a slight elevation of CSF proteins, and the patient tested positive for serum anti-GAD antibodies. The patient responded favorably to a seven-day course of intravenous methylprednisolone, five days of intravenous immunoglobulin (IVIG), and oral corticosteroids. Subsequent treatment consisted of monthly IVIG, azathioprine, and vedolizumab, resulting in no neurologic sequelae except mild amnesia. A follow-up MRI at three months showed a nearly complete disappearance of the lesions. This is the first reported case of anti-GAD-associated encephalitis occurring in the presence of Crohn's disease.

Abstract
Background and Aim Radioembolization (RE) is a one of the palliative treatments that have been used to down stage and/or increase the survival time in intermediate-advanced stages of HCC. We aimed to evaluate the clinical impact of RE and the clinical use of the albumin-bilirubin (ALBI) score as a predictor for survival in HCC patients. Materials and Methods Fifty-nine unresectable hepatocellular carcinoma (HCC) patients were enrolled. RE was performed in 28 of them (group 1) and 31 patients were followed up in the natural course (NC) (group 2). Patients were classified according to the Child-Pugh score (only cirrhotic patients), Barcelona clinic liver cancer (BCLC) staging, and ALBI scores were also calculated. Results All patients in Group 1 were cirrhotic and their BCLC stages were as follows: 60.7% stage B and 39.3% stage C. In Group 2, 83.9% of patients were cirrhotic and their BCLC stages were as follows: 9.7% stage B, 51.6% stage C, and 38.7% stage D. Mortality rates were 82% and 100% in Groups 1 and 2, respectively. The median overall survival (OS) was 13.5 months (95% CI: 10.4-16.6 months) and 4.5 months (95% CI: 3.5-5.5 months) in Groups 1 and 2, respectively (p=0.000). When RE was applied to patients with ALBI Grade 1 and 2, the median OS was statistically higher than in the NC group, respectively (p<0.001, p<0.001). Conclusion RE is an effective treatment method at the advanced stages of HCC. The ALBI score is a more useful and practical than the other prognostic tools.

Abstract
BACKGROUND AND AIM This study aimed to detect mutations in the HBV S gene and evaluate their relationship to occult hepatitis B virus (HBV) infection (OBI). METHODS The study included 32 patients with negative serum HBsAg and HBV DNA who underwent liver biopsy due to different clinical indications defined as the OBI group and 32 patients who underwent liver biopsy due to chronic hepatitis B (CHB) as the comparison group. The HBV S gene region was amplified by Nested PCR, and Sanger sequencing was performed. RESULTS At least one amino acid (aa) mutation was detected in the major hydrophilic region (MHR) of the HBV S gene in 14/32 (43.75%) of the patients with OBI and 8/32 (25.0%) with CHB. The genotype of all patients with OBI and CHB was HBV/D. Although 9 (28.1%) of the cases with OBI had sub-genotype HBV/D3, none of the patients with CHB had sub-genotype HBV/D3. Unlike patients with CHB, L15*, D33N, Q51P, V63F, L91I, P108S, T115I, P120L, T125M, Q129H, T189I, L216F, P217L mutations were detected in the HBV S gene in OBI cases. Also, P127T aa polymorphism was frequently detected. Mutation frequency in the HBV S gene in the major hydrophilic region (MHR) was higher in patients with OBI with sub-genotypes HBV/D3 and D2 than those with HBV/D1 and those with serotype HBV/ayw3 compared to those with HBV/ayw2 (p < 0.05). CONCLUSIONS Sub-genotypic-specific mutation patterns were seen in the "a" determinant region and T helper cell epitopes of HBsAg, especially in the C-terminus domain; this may be associated with OBI.

Abstract
Aim: To determine the prevalence of occult hepatitis B (HBV) infection (OBI) in patients with nonviral liver disease. Materials & methods: This study included 83 HBsAg-negative patients followed up at a gastroenterohepatology clinic. The presence of HBV DNA was investigated by using an in-house nested-PCR method applied to liver parenchymal biopsy samples obtained from patients who underwent due nonviral chronic liver disease. Results: OBI was detected in 19 (22.9%) of the 83 cases, in 11 (44%) of 25 anti-HBc-positive patients, and 15 (31.9%) of 47 anti-HBc and/or anti-HBs antibodies-positive patients. Conclusion: There is a considerable prevalence of OBI among patients with nonviral chronic liver disease. Therefore, it is suggested that closely monitoring HBV can be useful to prevent or more effectively manage possible OBI-related complications among patients with nonviral chronic liver disease, especially those who are HBsAg seronegative or anti-HBV antibody seropositive.

Abstract
Irritable bowel syndrome with diarrhoea (IBS‐D) and functional diarrhoea (FDr) are the two major functional bowel disorders characterized by diarrhoea. In spite of their high prevalence, IBS‐D and FDr are associated with major uncertainties, especially regarding their optimal diagnostic work‐up and management. A Delphi consensus was performed with experts from 10 European countries who conducted a literature summary and voting process on 31 statements. Quality of evidence was evaluated using the grading of recommendations, assessment, development, and evaluation criteria. Consensus (defined as >80% agreement) was reached for all the statements. The panel agreed with the potential overlapping of IBS‐D and FDr. In terms of diagnosis, the consensus supports a symptom‐based approach also with the exclusion of alarm symptoms, recommending the evaluation of full blood count, C‐reactive protein, serology for coeliac disease, and faecal calprotectin, and consideration of diagnosing bile acid diarrhoea. Colonoscopy with random biopsies in both the right and left colon is recommended in patients older than 50 years and in presence of alarm features. Regarding treatment, a strong consensus was achieved for the use of a diet low fermentable oligo‐, di‐, monosaccharides and polyols, gut‐directed psychological therapies, rifaximin, loperamide, and eluxadoline. A weak or conditional recommendation was achieved for antispasmodics, probiotics, tryciclic antidepressants, bile acid sequestrants, 5‐hydroxytryptamine‐3 antagonists (i.e. alosetron, ondansetron, or ramosetron). A multinational group of European experts summarized the current state of consensus on the definition, diagnosis, and management of IBS‐D and FDr.

Abstract
BACKGROUND Patients with Crohn's disease experience major deterioration in work productivity and quality of life. We aimed to provide the long-term effects of anti-tumor necrosis factor agents on work productivity and activity impairment and quality of life in patients with Crohn's disease using the Inflammatory Bowel Disease Questionnaire and the Short-Form Health Survey-36. METHODS Patients with Crohn's disease and initiated an anti-tumor necrosis factor treatment were included and followed up for 12 months in this observational study. RESULTS A total of 106 patients were included in this study, and 64.2% of the patients were males. Mean [± standard deviation] age was 36.8 [± 10.9] years. At baseline, mostly perianal fistulas [65.7%] were observed [n = 23]. Intestinal stenosis was detected in 34.9% of the patients [n = 37], and most of the stenosis was located in the ileum [70.6%] followed by the colon [20.6%]. Extraintestinal symp- toms were observed in 24 patients [22.6%]. Most frequent extraintestinal symptom was arthritis with 71.4% [n = 15]. Mean time from first symptom to initiation of anti-tumor necrosis factor treatment was 6.3 [± 5.0] years. Improvements in work productivity and activ- ity impairment scores throughout 12 months were -24.1% [P = .003] for work time missed, -18.0% [P = .006] for impairment at work, -8.5% [P = .160] for overall work impairment, and -17.0% [P < .001] for daily activity impairment. Similarly, significant improvements [P < .001] were detected in all components of the Inflammatory Bowel Disease Questionnaire when compared to baseline. Statistically sig- nificant improvements [P < .05] were detected for all components of Short-Form Health Survey-36 except for mental health [P = .095]. CONCLUSION Our study indicates the significant improvement in work productivity and activity impairment and quality of life of patients with Crohn's disease who receive long-term anti-tumor necrosis factor treatment.

Abstract
Backgrounds and Aims In autoimmune hepatitis, there are uncertainties about whether to discontinue
the treatment, when the treatment should be discontinued, and the risks of
relapse in the cases where remission is achieved with immunosuppressive
therapy. In this study, patients with AIH, whose immunosuppressive
treatments were discontinued, were evaluated for the rates of remission and
the risk of relapse. Materials and Methods A total of 119 patients, who were diagnosed with AIH based on the AIHG
scoring systems between 1990 and 2015, were evaluated. Patients were
receiving standard azathioprine and steroid therapy. The treatment was
discontinued in patients, who had been receiving treatment for at least
2 years, who had no clinical complaints, and whose aminotransferases were
normal and when an increase occurred in AST values more than two times the
normal after the treatment was interrupted, the case was considered as a
relapse. Results Among the patients, 83%(n = 99) were women. When the
patients were diagnosed with AIH, their mean age was 36 ± 16(8–79) years;
70.6%(n = 84) were type 1, 3.4%(n = 4)
type 2, and 26%(n = 31) were autoantibody-negative AIH. At
the time of discontinuation, liver biopsy was performed in 8 of the patients
and minimal-mild abnormalities were detected. Patients whose treatment was
discontinued received treatment for an average of 101 ± 75(range: 24–280,
median: 68.5) months; and, they were followed up for an average of 19
(1–110) months during the period without medication. Relapse occurred in
67%(n = 12) of the patients with drug withdrawal.
Relapse occurred within the first 12 months in 67% of these patients
(n = 8) and developed with an acute hepatitis attack in
42%. None of the clinical, laboratory, and histological data were found to
be effective on relapse. Conclusion In patients with AIH, relapse occurs in two-thirds of patients within an
average of 19 month after the discontinuation of the medication. Most
relapses occur at the early period and they are accompanied by an acute
hepatitis attack.

Abstract
Surgical resection is an unavoidable part of the current treatment options for Crohn's disease (CD), and more than half of patients develop recurrence. The aim of this study was to investigate the predictors for recurrence in the long-term follow-up of CD patients after surgery.Medical records of consecutive CD patients who were operated on between January 2003 and January 2015 were retrospectively analyzed. Data including demographic and clinical characteristics of the patients were recorded. Recurrence was evaluated based on the Crohn's Disease Activity Index or endoscopic findings.The majority of 112 patients were males (n = 64, 57.1%), and 61 (54.4%) of them were active smokers. The median follow-up was 113 (range: 61-197) months. Disease recurrence occurred in 16 (14.3%) patients at a median of 13.5 months. The endoscopic recurrence rate was 8% (n = 9) at 1 year, 12.5% (n = 14) at 5 years, and 13.4% (n = 15) at 10 years. One (0.9%) patient underwent colonoscopic balloon dilatation at 1 year, and 7 (6.3%) patients needed re-resection at a median of 36 months. The age of the patient at the time of diagnosis (P = .033), penetrating disease behavior (P = .011), intra-abdominal abscess (P = 0.040) and, concomitant fistula and intra-abdominal abscess (P = .017) were associated with disease recurrence.Our study results suggest that the patients' age at the time of diagnosis, penetrating disease, intra-abdominal abscess, and concomitant fistula and abscess are the risk factors for CD recurrence after surgery.

Abstract
INTRODUCTION COVID-19 caused by the SARS-CoV-2 continues to spread rapidly across the world. In our study, we aim to investigate the relationship between the liver enzymes on admission (AST, ALT, ALP, GGT) and severity of COVID-19. We evaluated course of disease, hospital stay, liver damage and mortality. MATERIALS AND METHODS Our study included 614 patients who were hospitalized with the diagnosis of COVID-19 between 03.16.20 and 05.12.20. Patients with liver disease, hematological and solid organ malignancy with liver metastases were excluded, resulting in 554 patients who met our inclusion criteria. We retrospectively evaluated liver transaminase levels, AST/ALT ratio, cholestatic enzyme levels and R ratio during hospital admission and these were compared in terms of morbidity, mortality and clinical course. RESULTS Mean age of 554 subjects were 66.21±15.45 years, 328 (59.2%) were men. The mean values of liver enzymes on admission were AST (36.2±33.6U/L), ALT (34.01±49.34U/L), ALP (78.8±46.86U/L), GGT (46.25±60.05U/L). Mortality rate and need for intensive care unit were statistically significant in subjects that had high ALT-AST levels during their admission to the hospital (p=0.001). According to the ROC analysis AST/ALT ratio was a good marker of mortality risk (AUC=0.713: p=0.001) and expected probability of intensive care unit admission (AUC=0.636: p=0.001). R ratio, which was used to evaluate prognosis, showed a poor prognosis rate of 26.5% in the cholestatic injury group, 36.1% in the mixed pattern group and 30% in the hepato-cellular injury group (p 0.001). CONCLUSIONS ALT-AST elevation and AST/ALT ratio >1 was associated with more severe course and increased mortality in COVID-19.

Abstract
Background (Pegylated) Interferon ([Peg]IFN) therapy leads to response in a minority of chronic hepatitis B (CHB) patients. Host genetic determinants of response are therefore in demand. Methods In this genome-wide association study (GWAS), CHB patients, treated with (Peg)IFN for at least 12 weeks ± nucleos(t)ide analogues within randomized trials or as standard of care, were recruited at 21 centers from Europe, Asia, and North America. Response at 24 weeks after (Peg)IFN treatment was defined as combined hepatitis B e antigen (HBeAg) loss with hepatitis B virus (HBV) DNA <2000 IU/mL, or an HBV DNA <2000 IU/mL for HBeAg-negative patients. Results Of 1144 patients, 1058 (92%) patients were included in the GWAS analysis. In total, 282 (31%) patients achieved the response and 4% hepatitis B surface antigen (HBsAg) loss. GWAS analysis stratified by HBeAg status, adjusted for age, sex, and the 4 ancestry components identified PRELID2 rs371991 (B= −0.74, standard error [SE] = 0.16, P = 3.44 ×10–6) for HBeAg-positive patients. Importantly, PRELID2 was cross-validated for long-term response in HBeAg-negative patients. G3BP2 rs3821977 (B = 1.13, SE = 0.24, P = 2.46 × 10–6) was associated with response in HBeAg-negative patients. G3BP2 has a role in the interferon pathway and was further examined in peripheral blood mononuclear cells of healthy controls stimulated with IFNα and TLR8. After stimulation, less production of IP-10 and interleukin (IL)-10 proteins and more production of IL-8 were observed with the G3BP2 G-allele. Conclusions Although no genome-wide significant hits were found, the current GWAS identified genetic variants associated with (Peg)IFN response in CHB. The current findings could pave the way for gene polymorphism-guided clinical counseling, both in the setting of (Peg)IFN and the natural history, and possibly for new immune-modulating therapies.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is an increasing problem worldwide. Determining a prognosis is important for the management of HCC. AIM We aimed to investigate the impact of interleukin (IL)-29, galectin-3, leptin, fibronectin and protease-activated receptor-1 on the prognosis and diagnosis of patients with HCC. MATERIALS AND METHODS 60 HCC patients (75% male) and 20 healthy volunteers (70% male) were enrolled in this prospective study. Serum samples were obtained during the first admission before any adjuvant or metastatic treatments were administered. Serum biomarkers were determined using ELISA kits. RESULTS All patients had cirrhosis, and the Child - Pugh stages were as follows: 61.5% Child - Pugh A, 35.9% Child - Pugh B and 2.6% Child - Pugh C (61.7% hepatitis B virus, 11.7% hepatitis C virus, 6.7% hepatitis B virus + hepatitis C virus, 11.7% alcoholic and 8.3% cryptogenic). Fifty-three percent of the HCC patients died within a median of 7.5 months. The mean serum level of IL-29 in patients with HCC was higher than that in the control group (32.55 pg/ml vs 11.46 pg/ml, p < 0.015). Galectin-3 levels were significantly higher in the HCC group (6.7 ng/ml vs 1.38 ng/ml, p < 0.001). Fibronectin levels were higher in the control group than in the HCC group (260 635 ng/ml vs 257 353 ng/ml). However, the mean protease-activated receptor-1 and leptin levels were similar between the two groups (p > 0.05). The biomarkers were divided into two groups according to their median level. In the log rank analysis, biomarkers had no effect on survival (p > 0.05). CONCLUSIONS IL-29 and galectin-3 levels were significantly higher in HCC patients. Although IL-29 and galectin-3 can be used as diagnostic markers for HCC, they had no prognostic value in HCC patients.

Abstract
BACKGROUND Crohn's disease (CD) primarily involves gastrointestinal tract; however, it can present with extraintestinal manifestations (EIMs), which leads to significant morbidity. Frequency of EIMs and associated risk factors vary due to genetic and environmental differences in studies. AIM To examine the frequency and risk factors associated with EIMs in CD. METHOD Patients with CD under follow-up from March 1986 to October 2011 were included in this study. Demographics, type of EIMs, autoimmune diseases, and clinical features of CD were recorded. Frequency of EIMs and associated risk factors were analyzed. RESULTS Three hundred thirty-six patients with CD were included in the study (mean follow-up duration 7.54 years). 55.4% (n: 186) were male and the mean age at diagnosis of CD was 30.6 years (range, 10.3-68.2 years). At least one EIM was detected in 47.3% and multiple EIMs in 22.9% of the cohort. Oral, joint, and skin involvements (32.4%, 24.7%, 9.2%, respectively) were the most common EIMs. Female gender (OR: 2.19, 95% CI: 1.34-3.58, p = 0.001), corticosteroid usage (OR: 2.32, 95% CI: 1.28-4.22, p = 0.007), and positive family history (OR: 5.61, 95% CI: 1.95-3.58, p = 0.001) were independent risk factors for EIM development. Colonic involvement (OR: 3.93, 95% CI: 1.59-9.68, p = 0.003), no surgical operation (OR: 2.31, 95% CI: 1.14-4.68, p = 0.020), and corticosteroid usage (OR: 2.85, 95% CI: 1.07-7.61, p = 0.037) were independent risk factors for multiple EIM development. CONCLUSION Although the immunological and clinical associations between EIMs and CD cannot be fully elucidated, identifying specific relationships of immune-mediated diseases will help to better understand CD pathogenesis.

Abstract
Aim To meet the current need in different European countries for improving prescribing in older adults, we aimed to create an update screening tool getting origin from the two user friendly criterion sets: the STOPP/STARTv2 criteria and CRIME criteria. Findings Based on thorough literature review, 55 criteria were added, 17 criteria were removed, and 60 criteria were modified. As a result, 153 TIME criteria composed of 112 TIME-to-STOP and 41 TIME-to-START criteria were introduced. Message TIME criterion set is an update screening tool reported from Eastern Europe that included experts from geriatrics and other specialties frequently giving care to older adults and some additional practical explanations for clinical use. Electronic supplementary material The online version of this article (10.1007/s41999-020-00297-z) contains supplementary material, which is available to authorized users. Purpose To improve prescribing in older adults, criterion sets have been introduced from different countries. While current criterion sets are useful to some extent, they do not meet the need in some European countries. Turkish inappropriate medication use in the elderly (TIME) criteria was planned to meet this need. Methods In phase 1, the user friendly sets: STOPP/START version2 and CRIME criteria were combined. National experts composed of geriatricians and non-geriatricians were invited to review and comment. In phase 2, thorough literature review was performed and reference-based revisions, omissions, and additions were made. Explanatory additions were added to some criteria to improve application in practice. In phase 3, all working group members reviewed the criteria/explanations and agreed on the final content. Results Phase 1 was performed by 49 expert academicians between May and October 2016. Phase 2 was performed by 23 working group academicians between October 2016 and November 2018 and included face-to-face interviews between at least two geriatrician members and one criterion-related specialist. Phase 3 was completed between November 2018–March 2019 with review and approval of all criteria by working group academicians. As a result, 55 criteria were added, 17 criteria were removed, and 60 criteria were modified from the first draft. A total of 153 TIME criteria composed of 112 TIME-to-STOP and 41 TIME-to-START criteria were introduced. Conclusion TIME criteria is an update screening tool that differs from the current useful tools by the interactive study of experts from geriatrics and non-geriatrics, inclusion of practical explanations for some criteria and by its eastern European origin. TIME study respectfully acknowledges its roots from STOPP/START and CRIME criteria. Studies are needed whether it would lead improvements in older adults’ health.

Abstract
BACKGROUND The HBV core protein plays a major role in host immune response. Mutations occurring in the HBV core gene may cause alterations in the major epitopes being effective in the host immune response. Until now, the persistent effects of core gene mutations on HBV infections have not been fully understood. The aim of this study is to analyze the core gene mutations for epitopes in the T lymphocytes [T helper (Th) and cytotoxic (CTL)] and B cell and C terminal region in patients with chronic hepatitis using ultra-deep pyrosequencing (UDPS) method. METHODS Eleven patients with chronic hepatitis B infection were included in the study. Amplification of the core gene was performed by a conventional PCR method. Mutations in the epitopes for T lymphocytes (Th and CTL) and B cell and in the C terminal region of HBV core gene were screened by UDPS. These mutations were analyzed in HBeAg positive and negative patients. RESULTS The minimum percentages of amino acid substitutions were found with 0.9% in HBeAg positive patients and 1.2% in negative patients. The number of missense mutation was higher in patients with HBeAg positive than negative patients (p < 0.005). The number of amino acid substitutions in the region of aa49 - 69 in the Th epitopes was found to be the highest in both HBeAg positive and negative patients. The mutation frequency was higher in the C-terminal region of the core protein compared to the Th, CTL, and B cell regions and these were more common in subjects with high-grade fibrosis. Some types of mutations (V27I, R47H, Y132I, R174STOP, S181P, Q182K) were only detected in subjects with liver cirrhosis. CONCLUSIONS Unlike literature, our results show that there is no significant increase in number of mutations in the core gene of the virus during the anti-HBe positive period. The role of low abundance variants and mutations in the immune system can be understood using methods such as UDPS in the near future.

Abstract
Introduction Gastroesophageal reflux disease (GERD) is more frequent in patients with diabetes mellitus (DM).The aim of the present study was to evaluate gastroesophageal reflux (GER) in asymptomatic patients with DM using 24-h pH impedance.
Materials and Methods 19 healthy controls and 35 patients with DM without typical GERD symptoms were enrolled in the study. A 24-h pH-impedance study, esophageal manometry and gastroscopy were performed on all patients with DM. In the control group, an impedance study was performed on all subjects, and gastroscopy and esophageal manometry were performed on those who consented to the procedures. Patients with diabetes were categorized as obese [body mass index (BMI)>30 kg/m2] or non-obese (BMI<30 kg/m2) and both groups were compared with healthy controls.
Results The mean BMI was similar in the control group (27.3±2.6 kg/m2) and the diabetic group (28.7±5 kg/m2) (p>0.05).Erosive esophagitis was found in 7.5% of the DM group. Esophageal dysmotility was higher in diabetics compared to the control group (45.5 vs. 11%, p=0.04). Neuropathy was found to be an independent risk factor for dysmotility. The mean DeMeester score (DMS) (25.6±32.5 vs. 11.2±17, p=0.01) and bolus exposure time (2.1±1.3 vs.1.3±1.3 min, p=0.009) were higher in the DM group compared with the control group.The difference was mainly observed between obese diabetics and the control group (p<0.05). The mean DMS, pathologic acid reflux, and esophageal dysmotility rate were higher in patients without complications of DM (p<0.05). BMI was higher in these patients than in patients with complications.
Conclusion Acid reflux is common in patients with diabetes.GER is associated with the existence of obesity rather than hyperglycemia.

Abstract
BACKGROUND AND AIM Positron emission tomography/computed tomography(PET/CT) scans detects benign clinical conditions in addition to malignancy, and this leads to additional investigation and expenditure. The purpose of our study was to assess the endoscopic and histopathologic results of incidental 18F-FDG uptake in the GI tract. PATIENTS AND METHOD We enrolled 110 patients who underwent gastroscopy/colonoscopy for incidental GI tract involvement in PET/CT. Histopathologic and endoscopic results were compared with FDG uptake level, pattern of uptake(diffuse/focal), and site of involvement. RESULTS In our study, 52.7% of the patients were male and the mean age was 57±11 years. Among the participants, 47.3% and 52.7% of patients had upper GI tract and colorectal involvement in PET/CT, respectively. Gastritis and colonic polyps were the most common endoscopic diagnoses that caused FDG uptake in the upper and lower GI tract, respectively. Endoscopic evaluation was normal in 23.6% of patients with pathologic FDG involvement. The rates of adenomatous polyps, malignancy, and hyperplastic polyps were 18.5%, 13.6%, and 6.8%, respectively. The mean SUVmax were higher in malignant lesions than in non-malignant lesions (14.3±8.9 vs. 9.3±5.3)(p=0.02). Diffuse or focal FDG involvement patterns on PET/CT did not help to discriminate malignancy in the GI tract. CONCLUSION Malignancy was detected in only 13.6% of patients with FDG involvement in the GI tract, and the involvement pattern(diffuse/focal) and SUVmax did not differentiate malignancy.

Abstract
BACKGROUND HCV (Hepatitis C Virus) is genetically more diverse than HBV and HIV (Human Immunodeficiency Virus) and exists as quasispecies within infected individuals. This is due to the lack of efficient proofreading of the viral RNA-dependent RNA polymerase. Consequently, quasispecies emerge depending on the mutation rate of the viral polymerase, which may display a high level of genetic variability in a population. In infected individuals, HCV replicates and circulates as quasispecies composed of a complex mixture of different but closely related genomes that undergoes continuous change due to competitive selection and cooperation between arising mutants. The aim of this study is to investigate mutations in the NS5A region as a whole, including ISDR, PKRBD, IRRDR, and V3 of HCV genotype 1b cirrhosis patients being naive and nonresponders, treated with IFN (interferon) + ribavirin (RBN) by using an ultra-deep pyrosequencing method (UDPS). METHODS During the study, five patients (four females, and one male, mean age 59.8 ± 11 years) with HCV related cirrhosis were analyzed. Three patients received IFN + RBN for six months, but two patients did not receive any therapy. HCV-RNA concentrations in patients' sera were determined using a COBAS AMPLICOR HCV MONITOR Test, Version 2.0. Genotyping was performed by using a commercial reverse hybridization method, Line Probe Assay. The quasispecies for the NS5A region were investigated using UDPS. RESULTS All five patients were HCV genotype 1b (Mean Child-Pugh score 7.2 ± 1.9, 2 pts Child A, 2 pts Child B, and one pt Child C) but only one patient had hepatocellular carcinoma (HCC). A total of 19 different mutations were detected in each of the five patients (ranging from 3 to 6 mutations per patient). In all five patients, several mutations in the ISDR and PKR-BD regions were detected. On the other hand, mutations in the V3 and IRRDR regions were only detected in one patient. CONCLUSIONS UDPS is a new sequencing technology and a very sensitive method in detection of quasispecies with low frequency NS5A region mutations. These mutations may affect the antiviral response and development of HCC. However, further studies in larger number of patients should be conducted to clarify this hypothesis.

AIM To investigate clinical, etiological, and prognostic features in patients with hepatocellular carcinoma.
METHODS Patients with hepatocellular carcinoma who were followed-up from 2001 to 2011 were included in the study. The diagnosis was established by histopathological and/or radiological criteria. We retrospectively reviewed clinical and laboratory data, etiology of primary liver disease, imaging characteristics and treatments. Child-Pugh and Barcelona Clinic Liver Cancer stage was determined at initial diagnosis. Kaplan-Meier survival analysis was done to find out treatment effect on survival. Risk factors for vascular invasion and overall survival were investigated by multivariate Cox regression analyses.
RESULTS Five hundred and forty-five patients with hepatocellular carcinoma were included in the study. Viral hepatitis was prevalent and 68 patients either had normal liver or were non-cirrhotic. Overall median survival was 16 (13-19) mo. Presence of extrahepatic metastasis was associated with larger tumor size (OR = 3.19, 95%CI: 1.14-10.6). Independent predictor variables of vascular invasion were AFP (OR = 2.95, 95%CI: 1.38-6.31), total tumor diameter (OR = 3.14, 95%CI: 1.01-9.77), and hepatitis B infection (OR = 5.37, 95%CI: 1.23-23.39). Liver functional reserve, tumor size/extension, AFP level and primary treatment modality were independent predictors of overall survival. Transarterial chemoembolization (HR = 0.38, 95%CI: 0.28-0.51) and radioembolization (HR = 0.36, 95%CI: 0.18-0.74) provided a comparable survival benefit in the real life setting. Surgical treatments as resection and transplantation were found to be associated with the best survival compared with loco-regional treatments (log-rank, P < 0.001).
CONCLUSION Baseline liver function, oncologic features including AFP level and primary treatment modality determines overall survival in patients with hepatocellular carcinoma.

Abstract
Hepatocellular carcinoma (HCC) is the most common primary malignancy of the liver, and extrahepatic metastases are typically found during disease progression. The incidence of adrenal metastasis (AM) from HCC in autopsy series ranges from 4.6 to 12.5%, and it is the second most common site of metastasis after the lungs. To date, there have been few reports of patients who underwent adrenalectomy for isolated AM from HCC after liver transplantation (LT). A woman aged 55 years was referred to our clinic for the evaluation of a right adrenal mass that was detected by abdominal ultrasonography at another center. She had undergone liver transplantation secondary to HCC and acute liver failure due to cryptogenic liver cirrhosis 138 months previously. She had been followed up for 5 years following LT after which she declined to continue with further follow-up. After radiologic and biochemical evaluation, she underwent adrenalectomy and the histopathologic examination revealed a 10 × 8 × 7-cm adrenal mass, which was considered to be an isolated AM from HCC. To our knowledge, this is the first case of isolated AM from HCC in the literature that was diagnosed 138 months after liver transplantation. Isolated AM from HCC after LT is rare and might be detected a long time after LT. Curative surgical resection of isolated metachronous AM from HCC in the absence of disseminated disease might provide for an acceptable disease-free period after adrenalectomy.

Abstract
Background/Aims There are limited data about the relation between belching and irritable bowel syndrome (IBS). We aim to evaluate belching in patients with IBS. Methods Twenty-five patients with IBS and 12 healthy volunteers were enrolled in the study. IBS was diagnosed in accordance with the Rome III criteria. All patients were questioned about the presence of symptoms for belching, gastroesophageal reflux disease, and dyspepsia. Esophageal manometry and 24-hour pH-impedance were performed in all patients and healthy volunteers. Each of the patients with IBS underwent gastroscopy and colonoscopy. Results Demographic features were similar in both groups (P > 0.05). The belching rate was 32% in patients with IBS. The mean DeMeester score was significantly higher in IBS patients (13.80 ± 14.40 vs 6.04 ± 5.60, P = 0.027) and 24% of patients had pathologic acid reflux (DeMeester score > 14). Gastroscopy was normal in all patients. Symptom association probability positivity was detected in 24% of patients in the impedance study. The rate of weak acid reflux was also significantly higher in patients with IBS (97.00 ± 56.20 vs 58.20 ± 29.30, P = 0.025). The number of supine gas reflux (7.50 ± 6.40 vs 2.42 ± 2.80, P = 0.001) and supragastric belches was significantly higher in patients with IBS (51.20 ± 41.20 vs 25.08 ± 15.20, P = 0.035). Although the number of gastric belching was higher in controls, the difference did not reach statistical significance (12.10 ± 17.60 vs 4.90 ± 3.80, P = 0.575). We did not find any correlation between belching and any symptoms of IBS. Conclusions Belching is frequent in patients with IBS. Non-erosive reflux disease is frequent in IBS, which may be related to supragastric belching.

Abstract
BACKGROUND AND STUDY AIMS There is still need for accurate markers for early diagnosis of hepatocellular carcinoma (HCC) and assessment of prognosis. The aim of this study is to investigate interleukin (IL)-32, IL-1 beta, IL-18, vascular cell adhesion molecule (VCAM)-1, and epithelial cell adhesion molecule (EpCAM) in the diagnosis and assessment of prognosis of HCC. PATIENTS AND METHODS Fifty patients with HCC and 15 healthy volunteers were enroled into this prospective study. Serum samples were obtained at the first admission before any treatment was given. Serum IL-32, IL-1 beta, IL-18, VCAM-1, and EpCAM levels were determined using ELISA kits. RESULTS The mean age of the patient group and controls was 60±9years and 56±8years, respectively. The mean serum level of IL-32 was higher in patients with HCC than in the control subjects (65.1 vs. 14.1pg/mL; p<0.001). IL-18 levels were significantly higher in the HCC group (546.5 vs. 157.8pg/mL; p<0.001). EpCAM (20.3 vs. 1.5pg/mL; p<0.001) and VCAM (6.5 vs. 1.8μg/mL; p<0.001) levels were also higher in patients with HCC. The mean level of IL-1 beta in the HCC group was similar to that in the control subjects (1.9 vs. 1.9pg/mL; p=0.97). Fifty-eight per cent of the patients with HCC died at 7.3months (median). Cytokine levels except EpCAM did not correlate with survival (p>0.05). Alpha-foetoprotein, IL-32, IL-18, EpCAM, and VCAM had valuable cutoff levels to differentiate between patients with HCC and control group (p<0.001). CONCLUSIONS Although cytokines can be a diagnostic marker for HCC, they did not have any significant prognostic value in patients with HCC. Only EpCAM may be used to determine the prognosis of HCC, thereby assisting with treatment management.

Abstract
BACKGROUND Management of pancreatic cysts is based on neoplastic-nonneoplastic discrimination. Endoscopic ultrasound (EUS) enables to differentiate neoplastic-nonneoplastic lesions and also allows fine-needle aspiration (FNA). In this study, we aim to assess feasibility and clinical relevance of cytological and biochemical analysis in differential diagnosis of cystic pancreatic lesions in patients who had undergone endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) due to pancreatic cysts. METHODS Participants were 96 patients who had undergone EUS-FNA for differential diagnosis of pancreatic cysts. Pancreatic cysts were classified as benign-mucinous, nonmucinous, and malignant according to patient history, physical examination, EUS appearance, and cystic fluid assessment. Tumor markers (CEA, CA(cancer antigens) 72.4, CA 19-9) , amylase, lipase and cytological assesment were compared between 3 different groups. Receiver-operating characteristics (ROC) curves were constructed to identify appropriate cut-off values. RESULTS Fluid CEA and CA 72.4 levels for benign-mucinous and malignant cysts were significantly higher than for nonmucinous cysts (P ≤ 0.04). A cut-off CEA level of 207 ng/mL differentiated mucinous etiology with a sensitivity of 72.7%, specificity of 97.7%, and accuracy of 89.5%. The sensitivity, specificity, and accuracy of the CA 72.4 cut-off level of 3.32 ng/mL were 80%, 69.5%, and 73.6%, respectively. CONCLUSION Cyst fluid CEA and CA 72.4 levels have a high accuracy in discriminating mucinous from nonmucinous cysts. When combined with cytology their accuracy rate increases.

Abstract
OBJECTIVES Serum alanine aminotransferase (ALT) is a controversial marker for disease monitoring in hepatitis B e antigen (HBeAg)-negative chronic hepatitis B (CHB) patients. The aim of this study was to determine the fibrosis stage and histological activity index (HAI) in HBeAg-negative CHB patients with persistently normal ALT (PNALT) and high serum HBV DNA (≥2000 IU/ml) and to investigate clinical risk factors for the requirement of treatment through the examination of liver biopsy specimens. METHODS HBeAg-negative CHB patients with PNALT (≤40 IU/l) and high serum HBV DNA (≥2000 IU/ml) were included. HBV fibrosis stage and HAI were scored according to the Ishak system. Multivariate logistic regression analysis was used to estimate the independent risk factors for fibrosis stage ≥2 and/or HAI ≥6. Receiver operating characteristic curve analysis was used to determine an optimal age cut-off for liver biopsy. RESULTS A total 120 patients were enrolled. These patients had a mean HBV DNA level of 123680±494500 IU/ml; the HBV DNA load was 2000-20000 IU/ml in 68 patients (56.6%) and ≥20000 IU/ml in 52 (43.4%). Eighteen patients (15%) had moderate-to-severe histological activity (HAI ≥6). Forty-three patients (35.9%) had a fibrosis stage ≥2. Forty-eight patients (40%) had a fibrosis stage ≥2 and/or HAI ≥6. On multivariate logistic regression analysis, independent variables associated with fibrosis stage ≥2 and/or HAI ≥6 included age and HBV DNA viral load. Patients with HBV DNA 2000-20000 IU/ml were more likely to require treatment compared to those with a viral load ≥20000 IU/ml. The optimal age cut-off to predict fibrosis stage ≥2 and/or HAI ≥6 was 46 years. CONCLUSIONS Significant liver damage was detected in 40% of CHB patients with PNALT and high HBV DNA upon biopsy. Age and HBV DNA viral load were independent predictors of significant liver damage. A biopsy to determine the degree of liver damage is advisable for CHB patients older than 46 years.

Abstract
We report a 44-year-old male Turkish patient with adult onset Still's disease (AOSD) complicated by acute severe hepatitis and hemophagocytosis. Initial investigations for fever and rapidly progressive elevation of liver function tests were not diagnostic. Routine evaluations of liver and bone marrow biopsies missed the fundamental pathology. Extremely elevated ferritin levels led to a more detailed search, and immunohistochemical staining with CD68 for macrophages revealed extensive hemophagocytosis in both the first and second bone marrow biopsies, as well as in the liver biopsy. Treatment with steroid and cyclosporine A induced complete remission.

Abstract
OBJECTIVE This study evaluated the risks and outcomes of capsule retention during capsule endoscopy (CE) for investigating small bowel disease. Capsule retention is the most serious complication of CE. METHODS Before CE, the gastrointestinal tract was evaluated for blockages with computerized tomography. Analysis of CE was made retrospectively. RESULTS Capsule endoscopy was used to investigate obscure bleeding (90.2%; n = 324) or other symptoms (9.8%; n = 35). The capsule retention rate was 11/359 (3.1%); it was retained in a malignant lesion area (adenocarcinoma or melanoma) in two patients (18.2%), in the small bowel in an ulcerated area in five patients (45.5%), and in the oesophagus/stomach in four patients (36.4%) due to dysmotility. None of the patients had symptoms of obstruction. CONCLUSIONS Scanning patients before CE did not predict capsule retention. Retention is a complication of CE, but occurs as a result of the underlying disease. The risk of retention is increased in patients with motility disorders, suspected small bowel ulcers or malignancies.

Abstract
Proton pump inhibitors (PPI) metabolism and pharmacokinetics are regulated by cytochrome P450 enzymes in the liver. Cytochrome P450 2C19 (CYP2C19) polymorphism plays an import role in the metabolism of PPIs. The three possible genotypes for CYP2C19 each has a distinct effect on the pharmacodynamics of PPIs. Homozygote extensive metabolizers (HomEM) are the most frequent genotype and have two wild-types (non-mutant) (*1/*1) alleles. HomEM is associated with increased enzyme activity, which increases the rate of PPI metabolism. Intragastric pH, which is required for eradication, is lowest in HomEM. In HomEMs, an insufficient increase in intragastric pH results in decreased anti-Helicobacter pylori (HP) efficacy of the antibiotics and, therefore, lower eradication rates. We determined whether the HP eradication rate would increase after high-dose PPI treatment of extensive PPI metabolizers who had been treated unsuccessfully with a standard PPI dose. In our report, increasing the PPI dosage in patients with genotype polymorphisms may be effective on eradication rates. Eradication rates are directly affected by CYP2C19 polymorphisms, and eradication treatments should be planned considering such genotypic polymorphisms. Hence, CYP2C19 genotyping prior to treatment may facilitate determination of the optimum PPI dose to improve the therapeutic outcome. However, further researches are required to confirm this hypothesis.

Abstract
BACKGROUND The relationship between chronic obstructive pulmonary disease (COPD) exacerbations and gastroesophageal reflux (GER) has been investigated less than asthma-GER. We aimed to evaluate the presence of GER in patients with COPD and its impact on exacerbations. METHODS We included 24 patients with stable mild-moderate stage COPD and 19 volunteers as the control group. We conducted a gastroesophageal reflux disease (GERD) symptom questionnaire, gastroscopy, manometry, and an ambulatory 24-h pH-impedance study. RESULTS According to the GERD questionnaire, only 5 (20.8%) patients with COPD had typical GER symptoms. According to the 24-h pH-impedance study, the mean DeMeester score (DMS) was 38.1 ± 34.6 in the COPD group and 13.3 ± 16.8 in the control group (p = 0.01). The acid reflux (DMS > 14.7) rate was higher in patients with COPD than in controls (73.9% vs 26.3%, p = 0.01). The symptom association probability positivity rate was 17.4% (n = 4) in the COPD group, which was similar to the controls (p = 0.11). The mean proximal extension rate of reflux (Z 17 cm) was 26.4 ± 12.9% in the COPD group. The proximal extent of reflux was positively correlated with the number of COPD exacerbations per year (p = 0.03, r = 0.448). In the motility results, only 2 (20%) patients in the control group had a minor motility disorder. Seventeen (70.8%) patients in the COPD group had a minor motility disorder, and 4 (16.7%) had major motility disorders (p < 0.001). CONCLUSION In our study, gastroesophageal reflux was frequent in patients with COPD, but only a quarter had typical reflux symptoms. The proximal extent of reflux may trigger frequent exacerbations of COPD.

Abstract
Transglutaminase 2 (TG2) has been implicated in wound healing, cellular differentiation, apoptosis and cell survival. TG2 activity increases following acute and chronic liver injury; however, the role of TG2 in tumors, is controversial. TG2 is a retinoid-inducible enzyme. We investigated the effects of retinyl acetate (RA) on the activity and levels of TG2 during the initiation and promotion stages of liver cancer. p-Dimethylaminoazobenzene (p-DAB) was used as initiator and 2, 3, 7, 8-tetrachlorodibenzo-p-dioxin (TCDD) was used as promoter in our model of carcinogenesis. Rats were divided into four groups of 24: control, corn oil control, p-DAB + TCDD, and p-DAB + TCDD + RA. Six rats from each group were sacrificed at days 30, 60, 90 and 120. TG2 activity decreased in the p-DAB + TCDD treated group, but TG2 immunostaining scores did not change by days 90 and 120. Neither TG2 enzyme activity nor the immunostaining score of TG2 protein changed in the tissues of the p-DAB + TCDD + RA group by days 90 and 120. TG2 activity was not be ameliorated by RA during the initiation or promotion stages of carcinogen induced liver cancer.

Abstract
AIM: To assess the clinical impact of capsule endoscopy (CE) in the long-term follow-up period in patients with obscure gastrointestinal bleeding (OGIB).
METHODS: One hundred and forty-one patients who applied CE for OGIB between 2009 and 2012 were retrospectively analyzed, and this cohort was then questioned prospectively. Demographic data of the patients were determined via the presence of comorbid diseases, use of non-steroidal anti-inflammatory drugs anticoagulant-antiaggregant agents, previous diagnostic tests for bleeding episodes, CE findings, laboratory tests and outcomes.
RESULTS: CE was performed on 141 patients because of OGIB. The capsule was retained in the upper gastrointestinal (GI) system in two of the patients, thus video monitoring was not achieved. There were 139 patients [62% male, median age: 72 years (range: 13-93 years) and a median follow-up duration: 32 mo (range: 6-82 mo)]. The overall diagnostic yield of CE was 84.9%. Rebleeding was determined in 40.3% (56/139) of the patients. The rebleeding rates of patients with positive and negative capsule results at the end of the follow-up were 46.6% (55/118) and 4.8% (1/21), respectively. In the multivariate analysis, usage of NSAIDs, anticoagulant-antiaggregant therapies (OR = 5.8; 95%CI: 1.86-18.27) and vascular ectasia (OR = 6.02; 95%CI: 2.568-14.146) in CE were detected as independent predictors of rebleeding. In the univariate analysis, advanced age, comorbidity, and overt bleeding were detected as predictors of rebleeding.
CONCLUSION: CE is a reliable method in the diagnosis of obscure GI bleeding. Negative CE correlated with a significantly lower rebleeding risk in the long-term follow-up period.

Abstract
Advances in technology have facilitated the common use of small-bowel imaging. Intraoperative enteroscopy was the gold standard method for small-bowel imaging. However, noninvasive capsule endoscopy and invasive balloon enteroscopy are currently the main endoscopic procedures that are routinely used for small-bowel pathologies, and the indications for both techniques are similar. Although obstruction is a contraindication for capsule endoscopy, it is not considered to be problematic for double-balloon enteroscopy. The most important advantage of double-balloon enteroscopy is the applicability of therapeutic interventions during the procedure; however, double-balloon enteroscopy has certain advantages as well as disadvantages.

Abstract
OBJECTIVE Patients with inflammatory bowel disease (IBD) show increased the prevalence of cytomegalovirus (CMV) infection due to the severity of the disease and the immunosuppressive treatments they receive. The aim of this study was to determine the prevalence of CMV infection in IBD patients and identify the risk factors for CMV infection with different demographic characteristics in IBD patients. PATIENTS AND METHODS We enrolled 85 patients diagnosed with IBD (43 with ulcerative colitis (UC) and 42 with Crohn's disease (CD)) in this prospective study. The clinical disease activities of UC and CD were assessed using Truelove-Witts and Crohn's disease activity index (CDAI). CMV infection was assessed by detection of DNA using real-time polymerase chain reaction (PCR) in blood samples and quantitative PCR in colonic biopsy specimens and by detection of inclusion bodies using hematoxylin-eosin staining. RESULTS Thirteen patients with IBD exhibited concomitant CMV infection. CMV infection was not detected in any of the patients in remission. Viral loads measured in the colonic mucosa of infected patients ranged from 800-7000 genome copies/mL total extracted DNA. The mean serum CMV DNA level was 1694 ± 910 copies/mL (range: 800-3800). The rate of steroid resistance in CMV-positive cases was significantly higher than that in CMV-negative cases (p = 0.001). CD with acute exacerbation was a risk factor for CMV disease (p = 0.04). All of the CMV-positive patients received immunosuppressive treatments. CONCLUSIONS CMV infection should be suspected in steroid-resistant UC and CD. Antiviral treatment improved the clinical outcome in steroid-resistant IBD cases with serum CMV DNA levels above 1000 copies/mL.

Abstract
OBJECTIVE Cytochrome P450 2C19 (CYP2C19) polymorphisms play an important role in the metabolism of proton pump inhibitors. Rabeprazole is primarily metabolized via non-enzymatic pathways. In this study, we determined whether rabeprazole- and pantoprazole-based eradication treatments were influenced by CYP2C19 polymorphisms. PATIENTS AND METHODS A total of 200 patients infected with Helicobacter pylori were treated with either 40 mg of pantoprazole or 20 mg of rabeprazole plus 500 mg of clarithromycin, 1000 mg of amoxicillin twice daily for 2 weeks. CYP2C19 genotype status was determined by Polymerase Chain Reaction (PCR)-restriction-fragment-length polymorphism. The genotypes of cytochrome P450 2C19 were classified as homozigote extensive metabolizer (HomEM), heterozigote metabolizer (HetEM) and poor metabolizer (PM). The CYP2C19 genotype of all patients, the effectiveness of the treatment, the effect of the genotypic polymorphism on the treatment were assessed. RESULTS The frequencies of HotEM, HetEM, PM were 78%, 19.5% and 2.5%, respectively. 48% (n = 96) of the patients received treatment with rabeprazole and 52% (n = 104) with pantoprazole. The eradication rate was 64.7% for HomEM, 79.4% for HetEM, 100% for PM (p = 0.06). In HetEM, PM, are considered as a single group, the eradication rates were higher in patients with the HetEM and PM (HetEM+PM) genotypes than in those with the wild-type genotype (81.8 vs. 64.7% p = 0.031). Among the patients treated with rabeprazole, the eradication rates were significantly lower in those with the HomEM genotype than in those with the HetEM+PM genotypes (60% vs. 85.7% p = 0.023). CONCLUSIONS The genotypic polymorphism is effective on the rate of eradication. Eradication treatment rate with rabeprazole is influenced by CYP2C19 genotype.

Abstract
OBJECTIVE Pathogenesis of functional dyspepsia (FD) is complex. Melatonin is synthesized in enterochromaffin cells (EC) of the digestive system. It may influence gut function. The aim of this study is to evaluate the serum melatonin levels in FD patients. PATIENTS AND METHODS A total of 57 FD patients, and 12 healthy controls were enrolled in this study between 2008-2010 years. Diagnosis of FD was established based on the Rome III Criteria. Blood samples were taken at 10 a.m. and serum samples were stored in -85°C. Serum melatonin levels were determined by an enzyme-linked immunosorbent assay (ELISA) kit. (polyclonal Kennaway G280 anti-melatonin antibody, Bühlmann Laboratories AG, Schönenbuch, Switzerland). RESULTS Twenty-three (40.3%) patients were male, and, mean age was 44.3 ± 12.1 years. Mean age of control group was 38.5 ± 11.8 years, and 7 of them were male. The mean serum concentration of melatonin in patients and control group were 31.19 ± 43.4 pg/ml and 14.8 ± 20.9 pg/ml, respectively (p < 0.05). Melatonin levels were significantly higher in male patients (38.6 ± 55 pg/ml vs 12.8 ± 22 pg/ml, p < 0.05). However, melatonin levels were similar in females (p > 0.05). CONCLUSIONS The serum melatonin levels were significantly higher in male patients with functional dyspepsia. High nocturnal melatonin secretion may play a role in the pathogenesis of functional dyspepsia, especially in males.

Abstract
BACKGROUND Tachykinins (TKs) are a family of endogenous peptides widely expressed in the central and in the peripheral nervous systems as well as in the gastrointestinal (GI) tract. They act as full agonists at three different membrane receptors neurokinin (NK) 1, NK2, and NK3, which are G protein-coupled receptors and in the GI tract are expressed both on neurons and effector cells. PURPOSE This article reviews the literature concerning the role of TKs in the GI tract function in physiological and pathological conditions and their potential relevance in the treatment of functional GI disorders with particular reference to irritable bowel syndrome (IBS). The efficacy of NK1 antagonists in chemotherapy-induced and postoperative nausea and vomiting is well established. While pharmacodynamic studies have reported conflicting and negative results concerning the effects of NK1 and of NK3 antagonists, respectively, on the GI tract function in humans, clinical studies applying the NK3 antagonist talnetant in IBS-D were negative. Pharmacodynamic studies applying NK2 antagonists have suggested a role for antagonism of NK2 receptors in modulation of GI chemical-induced altered motility and of stress-induced altered bowel habits. Clinical studies and in particular a recently completed Phase 2 study have reported that the NK2 antagonist ibodutant is effective and safe in treating symptoms of D-IBS, especially in females.

Abstract
BACKGROUND & AIMS To evaluate the efficacy of tenofovir in chronic hepatitis B (CHB) patients with adefovir resistance (ADF-R) and suboptimal response to adefovir (ADF-S). METHODS Nucleos(t)ide analogue (NA)-naïve patients and patients with previous adefovir failure receiving tenofovir therapy for at least 6 months were included in the study. Biochemical and virological tests were obtained at baseline and 3-month intervals in the first year and every 6 months thereafter. The primary outcome measure was complete virological response (CVR) (HBVDNA < 20 IU/ml). CVR rates were calculated by Kaplan-Meier analysis, and a multivariate Cox proportional hazard model was generated to find out factors independently associated with CVR. RESULTS A total of 165 patients (118 men, mean age 42 ± 12, 64 HBeAg(+) ) were included in the study. There were 105 patients in NA-naïve, 32 patients in ADF-S and 28 patients in ADF-R groups. All patients in the ADF-R group had multidrug resistance patterns. Mean duration of tenofovir treatment was 29 ± 14 months. CVR rates in NA-naïve, ADF-S and ADF-R groups were 65% vs. 75% vs. 58% at 12th month, 77% vs. 87% vs. 79% at 24th month and 83% vs. 94% vs. 79% at 36th month respectively. According to multivariate Cox regression model, HBeAg positivity (HR = 0.56, 95%CI 0.36-0.86, P = 0.008), high baseline HBVDNA level (HR = 0.64, 95%CI 0.55-0.74, P < 0.001) and ADF-R (HR = 0.47, 95%CI 0.28-0.81, P = 0.006) were independent predictors for CVR. Seven patients encountered mild renal dysfunction and were managed by dose adjustments. CONCLUSION CVR rates during the follow-up show that tenofovir has a decreased, yet still potent in vivo efficacy against multidrug-resistant strains of HBV.

Abstract
PURPOSE Although some algorithms are defined for the treatment of advanced hepatocellular carcinoma (HCC), the expected survival cannot be prolonged as it is intended. Treatment options for this group of patients are limited. Radioembolization with yttrium-90 (Y-90) microspheres is a new treatment modality, which has also been used in advanced HCC patients. In this study, the authors aimed to assess the efficiency of radioembolization with Y-90 microspheres and evaluate prognostic factors that influence the survival in HCC patients. PATIENTS AND METHODS The authors retrospectively evaluated data of 29 HCC patients who had radioembolization with Y-90 resin or glass microspheres between May 2009 and January 2014. Patient survival was evaluated by using the Kaplan-Meier method. Subgroup comparisons in terms of age, sex, prior treatment status before radioembolization, tumor burden, time between HCC diagnosis and radioembolization, alpha fetoprotein (AFP) level before radioembolization, presence of portal vein thrombosis (PVT), hepatopulmonary shunt ratio, extrahepatic disease burden, multifocality, bilaterality, Eastern Cooperative Oncology Group (ECOG), Child-Pugh, and Barcelona Clinic Liver Cancer (BCLC) status were performed to evaluate prognostic factors that affected survival. RESULTS There were 29 HCC patients (mean age: 59.9±12 years) in the patient group. Grade ≤1 and 2 ECOG performance status was present in 19 and 10 patients, respectively. Twenty-six patients were classified as Child A and 3 patients as Child B. According to the BCLC staging system, 18 patients were in stage B and 11 patients were in stage C. PVT was diagnosed in 12 patients. The median follow-up was 15 months. The median overall survival was 17±2.5 months. BCLC disease stage was a significant prognostic variable associated with survival, but other parameters, even the presence of PVT, were found to be not significantly affecting survival. CONCLUSION Radioembolization provides favorable survival time in advanced HCC patients. Even patients who are not eligible for transarterial chemoembolization due to PVT can have radioembolization without a decrease in the median survival time.

Abstract
BACKGROUND & AIMS We investigated the association between interferon λ 3 (IFNL3) genotype (also known as interleukin 28B) and response to IFNα therapy in patients with chronic hepatitis D virus (HDV) infection. METHODS We studied IFNL3 genotypes of 32 patients (19 men; median age, 42.5 y) with chronic HDV infection. Nineteen patients (59%) were treated with pegylated IFNα and 13 patients (41%) were treated with standard IFNα, for at least 12 months. Levels of HDV RNA were measured before the initiation of treatment and every 6 months thereafter; patients were followed up for a median time of 16 months (range, 6-164 mo) after treatment ended. We used real-time polymerase chain reaction to classify the IFNL3 polymorphism rs12979860 as CC, CT, or TT, and rs8099917 as TT, GT, or GG. A virologic response was defined as undetectable HDV RNA in serum, and a sustained virologic response (SVR) was defined as undetectable HDV RNA after cessation of treatment until the end of the follow-up period. We evaluated the association between IFNL3 polymorphism and treatment response using univariate and multivariate analyses. RESULTS After treatment, a response was achieved in 16 patients (50%) and an SVR was achieved in 9 (28%). The percentages of patients with CC, CT, and TT at rs12979860 were 47%, 47%, and 6%, respectively; the percentages of patients with TT, GT, and GG at rs8099917 were 69%, 28%, and 3%, respectively. Rates of SVR were 27%, 27%, and 50% in patients with CC, CT, TT at rs12979860 (P = .78 for CC vs CT vs TT) and 36%, 11%, and 0% in patients with TT, GT, and GG at rs8099917 (P = .30 for TT vs GT vs GG). CONCLUSIONS The IFNL3 polymorphisms rs12979860 and rs8099917 do not significantly affect responses of patients with chronic HDV infection to treatment with IFNα.

Abstract
OBJECTIVE To assess the efficacy and adverse effects of infliximab in patients with Crohn's disease and ulcerative colitis who are resistant to conventional therapy or having fistulising type Crohn's disease. PATIENTS AND METHODS The patients with a diagnosis of inflammatory bowel disease received infliximab between 2007 and 2009 were followed-up prospectively. Infliximab 5 mg/kg was given at week 0, 2, 6, and every 8 weeks thereafter. Early and late adverse events occurring during the treatment were recorded for each patient. RESULTS There were 36 patients [mean age 35±12, 17 male] included in the study. Thirty-two (88%) patients were receiving concomitant long-term immunosuppressive therapy. Complete or partial response was obtained in 75% of all patients. At least one adverse event was observed in 10 (28%) patients. Anaphylaxis was seen in 2 (6%) patients, mild acute infusion reaction in 2 (6%) patients, hypotension in 2 (6%) patients, respiratory distress in 2 (6%) patients, skin rash and eruptions in 2 (6%) patients, one hypertension (3%) and one (3%) tightness in the chest. Treatment was continued in all except patients with anaphylaxis. No infection, tumour or cases of death were observed. CONCLUSIONS Several adverse events might be observed in patients who receive infliximab. Care should be given to patients whom treatment was restarted after a break in regard to anaphylaxis. No serious adverse event was observed during infliximab treatment except allergic events.

Abstract
Incidence of hepatitis B virus infection (HBV) has been greatly reduced globally after the introduction of universal vaccination programs. However, another potential threat was noticed almost 2 decades ago, which is the selection of antibody escape HBV strains. Antibody or immune escape strains of HBV carry mutations in the S gene which encodes "a" determinant region located at amino acid positions 124 to 149. Certain mutations in this region, which promotes antibody response, might lead to an alteration in the antigenicity of hepatitis B surface antigen (HBsAg). Anti-HBs might fail to neutralize the mutant virus and transmission or reappearance of infection in previously immunized individuals can be possible. Herein, we report a patient with known HBV seropositivity (HBsAg negative, anti-HBs positive, anti-HBc IgG positive) for more than 10 years who developed a symptomatic acute hepatitis due to occurrence of immune escape mutants in the absence of any immunosuppression or cytotoxic chemotherapy. To the best of our knowledge, this is the first reported case of acute hepatitis B due to escape mutations in a naturally immune patient.

Abstract
Neoplastic proliferation of plasma cells is called plasma cell dyscrasias, and these neoplasms can present as a solitary neoplasm or multiple myeloma. Extramedullary plasmacytoma, in particular pancreatic plasmacytoma, is a rare manifestation of multiple myeloma. Although computerized tomography is useful for the diagnosis of extramedullary plasmacytoma, there are no specific radiologic markers that distinguish it from adenocarcinoma. Histological confirmation by biopsy is necessary for accurate diagnosis and management of the tumor. Endosonography is the most sensitive method for the diagnosis of pancreatic tumors, and the use of fine needle aspiration by endosonography is associated with a lower risk for malignant seeding and complications. Here, we report a case of pancreatic plasmacytoma in newly identified multiple myeloma as diagnosed by endosonography. Endosonography is a reliable and rapid method for the diagnosis of extramedullary plasmacytoma. Therefore, endosonographic fine needle aspiration should be the first choice for histological evaluation when pancreatic plasmacytoma is suspected. Ideally, the pathology would be performed at the same site as endosonographic biopsy.

Abstract
Chronic hepatitis C (CHC) patients with treatment failure (TF) remain at risk of continuing fibrosis progression. However, it has not been investigated whether there is an increased risk of accelerated fibrosis progression after failed interferon-based therapy. We aimed to investigate long-term influence of TF on fibrosis progression compared with untreated patients with CHC. We studied 125 patients with CHC who underwent paired liver biopsies from 1994 to 2012. Patients with advanced fibrosis were excluded from the analysis. Sixty-three patients had TF, and 62 patients were treatment-naïve (TN). Annual fibrosis progression rate (FPR) was calculated, and significant fibrosis progression (SFP) was defined as ≥ 2 stage increase in fibrosis during follow-up. Multiple regression analyses were performed to find out independent predictors of FPR and SFP. Demographic characteristics and duration between paired liver biopsies were similar in TF and TN groups. Baseline alanine aminotransferase and gamma-glutamyl transferase (GGT) levels (71 ± 31 vs 47 ± 22, P < 0.001 and 49 ± 39 vs 36 ± 28, P = 0.027, respectively), baseline mean fibrosis stage (2.2 ± 0.7 vs 1.9 ± 0.7, P = 0.018) and histologic activity index (6.3 ± 1.9 vs 4.3 ± 1.6, P < 0.001) were higher in the TF group compared with the TN group. In regression analyses, the strongest independent predictor of fibrosis progression was the GGT level (OR: 1.03, 95%CI 1.01-1.5, P < 0.001). Treatment experience (OR: 5.97, 95%CI 1.81-19.7, P = 0.003) also appeared as an independent predictor of both FPR and SFP. Failed interferon-based CHC treatment may lead to accelerated FPR in the long-term compared with the natural course.

Abstract
The potential antiviral resistance mutations within hepatitis B virus (HBV) reverse transcriptase (RT) region for nucleos(t)ide analogues (NA) are not well known. Especially, the effect of pre-existing antiviral drug resistance mutations in untreated patients in comparison to the resistance developed after treatment is not still clear. Sixteen naive chronic hepatitis B patients were studied. None of the patients had received NA treatment prior to the serum samples being collected. Forty-two potential NA resistance (NAr) mutation sites were screened by ultra-deep pyrosequencing (UDPS). After therapy, mutations conferring treatment resistance were detected by LiPA. Serum samples taken before treatment showed no classic primary or compensatory/secondary drug resistance mutations. However, NAr mutations found in 6 isolates (37.5%) involved 7 positions including rtL91I, rtT128I, rtQ215P, rtF221Y, rtN238D, rtC256S, and rtI266G. Substitutions at 3 NAr mutation sites (rtT128I, rtN238D, and rtC256S) were detected in 3 unresponsive patients developing drug resistance after NA treatment. One patient with rtI266G mutation also developed drug resistance after lamivudine (LAM) therapy. However, the relationship between rtI266G mutation and NA drug resistance was not previously reported. These results suggest that association of potential mutations besides the primary and secondary/compensatory resistance mutations should be investigated. Investigation of NAr mutations before treatment may be important for the success of the treatment.

Abstract
BACKGROUND Substance P (SP) is a member of the neurokinin (NK) family and is one of the established neurotransmitters in the mammalian central and enteric nervous system. It is unclear whether NK1 receptors are involved in the control of gastric sensorimotor function in man. METHODS We studied the effects of aprepitant, an NK1 receptor antagonist used in the treatment of chemotherapy-induced emesis, on gastric sensorimotor function in healthy volunteers. Sixteen healthy volunteers (six males, 32.4 ± 2.7 years) were studied on three separate occasions after placebo, aprepitant 80 or 125 mg in randomized double-blind study to assess gastric compliance, perception to isobaric distensions, and gastric accommodation with a gastric barostat. KEY RESULTS Compared to placebo, both doses of aprepitant did not influence gastric compliance or sensitivity to gastric distension. Aprepitant 80 and 125 mg did not have any significant effects on gastric accommodation compared with placebo (mean postprandial gastric volume increase, respectively, 83.4 ± 28.4 vs 35.3 ± 16.2 vs 83.9 ± 30.4 mL, NS). Postprandial gastric compliance and sensitivity to distention were also not altered. CONCLUSIONS & INFERENCES In health, NK1 receptors do not appear to be involved in the control of gastric compliance, accommodation or sensitivity to distention in man.
