- Abstract
Background and Aim: The objective of the present study was to investigate the prevalence of metabolic-associated fatty liver disease (MAFLD) in patients with dyspepsia., Materials and Methods: A total of 909 consecutive patients who presented with dyspepsia at 8 tertiary care centers in Turkey between March 2019 and December 2019 were included., Results: The median age was 47 years. Among them, 30.3% of the patients were obese, 18.8% had type 2 diabetes mellitus (T2DM), 35.1% had metabolic syndrome, 84.8% had dyslipidemia, and 23.9% had hypertension. The prevalence of MAFLD was 45.5%. Among the patients with MAFLD, the prevalence of obesity, T2DM, metabolic syndrome, dyslipidemia, and hypertension was 43.3%, 24.9%, 52.5%, 92.3%, and 31.9%, respectively. MAFLD was significantly associated with all of the metabolic comorbidities (p<0.001). The median Fibrosis-4 Index score of the MAFLD patients was 0.88 (range: 0.1-9.5). Of note, 53 patients with hepatic steatosis did not meet the MAFLD criteria., Conclusion: The results of the present study indicated that there was a significantly high prevalence of MAFLD observed in daily clinical practice in Turkey. Early diagnosis and prevention efforts should be implemented to reduce disease progression, and a region-based strategy is recommended., Competing Interests: Conflict of Interest: The authors have no conflict of interest to declare., (© Copyright 2021 by Hepatology Forum - Available online at www.hepatologyforum.org.)

- Abstract
Within the hepatitis virus landscape, one incomplete virus, the hepatitis delta virus (HDV), appears to differ from hepatitis B and C viruses in the context as it still may not infrequently lead to complications of chronic liver disease and continues to be associated with significant liver-related mortality even when patients have received available treatment for it. Breakthrough therapies are so far lacking for HDV-infected patients and treatment has not changed since the discovery of HDV in 1977 and consists mainly of interferons. While there was little interest on the global epidemiology of HDV until recently, this has changed in the past 2 years and we are currently observing a stream of papers on the global epidemiology of HDV and commentaries about why prevalence estimates appear to differ so dramatically. This may be related to the fact that reliable data are not available for most of the countries. However, in the industrialized world, data on the epidemiology of HDV are expected to be of better overall quality. Hence, this review was undertaken to provide a detailed overview on the epidemiology of HDV infection in industrialized countries using data from representative larger countries. In industrialized countries, with maybe the exception of China, HDV infection is a disease of high-risk groups. Migrant groups and people who inject drugs are the most encountered high-risk groups. This review summarizes the dynamics of their contribution to the HDV epidemiology in industrialized countries of the west and the east.

- Abstract
Introduction: Socioeconomic factors play an important role in the prevalence of Helicobacter pylori (HP) infection. The aim of this study is to investigate HP prevalence among symptomatic patients in the upper socioeconomic segment of the population undergoing gastroscopy in an endemic urban region., Methodology: Over a 12-month period, data were collected from the first consecutive 1000 patients (500 from university hospital, 500 from community hospital) who had gastroscopy and HP evaluation., Results: Overall, 211/1000 patients (21.1 %) were found to have HP in gastric biopsies. The specificity, sensitivity, positive predictive value, negative predictive value and diagnostic accuracy of rapid urease test were 87.5%, 99.7%, 99%, 96.5%, and 96.9% respectively. Atrophic gastritis, gastric and duodenal ulcers were significantly more common in HP positive patients. Age based distribution of HP prevalence: > 6 decades (15.5%), 3rd-5th decades (26.1%), < 3rd decades (10.4%)., Conclusion: In an HP endemic country, the prevalence of HP infection among symptomatic patients belonging to the upper socioeconomic segment of the population appears to be markedly lower. The lowest prevalence in young patients is expected to result in future decrease in HP prevalence., Competing Interests: No Conflict of Interest is declared, (Copyright (c) 2020 Tan Attila, Mujdat Zeybel, Yesim Esen Yigit, Bulent Baran, Emel Ahishali, Emrah Alper, Fatih Aslan, Onder Ergonul, Zeynel Mungan.)

- Abstract
Purpose: Gastrointestinal bleeding remains the leading cause of morbidity and mortality for patients who need hemodialysis treatment. Our aim was to evaluate patients who needed hemodialysis and presented with bleeding during their hospital stay (uremic bleeding patients). Factors that increased the risk of bleeding and death were evaluated. Additionally, uremic bleeding patients were compared to non-uremic bleeding patients regarding gastrointestinal findings., Patients and Methods: Fifty-one uremic bleeding patients were compared to two control groups which included uremic (hemodialysis dependent and non-bleeding) and non-uremic (no renal insufficiency and bleeding) patients., Results: NSAIDs and anti-ulcer drug usage were more common in uremic bleeding and in uremic non-bleeding groups, respectively. Dialysis vintage was longer in uremic bleeding group. Comparison of uremic bleeding and non-bleeding uremic patients regarding the usage of ACEI or ARB drugs yielded non-significant results. Acute kidney injury, lower plasma albumin level and high CRP level were significantly increased the risk of mortality in uremic bleeding patients. Hospital stay more than 1 week was the only strong factor for mortality when multivariate analysis was performed. Gastroduodenal and duodenal ulcers were significantly detected in uremic bleeding and non-uremic bleeding patients; respectively., Conclusions: Hemodialysis patients presenting with gastrointestinal bleeding should be evaluated regarding use of prescriptions and efforts should be done in order to shorten their hospital stay and decrease their mortality. Effect of ACEI or ARB drugs should also be evaluated in future studies.

- Abstract
This study aims to investigate the frequency of irritable bowel syndrome (IBS) among healthcare professionals. A total of 394 healthcare professionals and 207 individuals who were selected as a control group were included in the study. A questionnaire form containing Rome III diagnostic criteria was administered to health workers and the control group. The study groups were evaluated according to age, gender, occupation, profession, presence of chronic disease, drug usage, smoking, awareness of IBS, alarm symptoms, and the type of IBS they have. Irritable bowel syndrome was diagnosed in 44 healthcare workers and 10 control group participants. Of the 44 healthcare professionals with IBS, 6 had alternate, 13 had constipated-dominant, and 25 had diarrhea-dominant IBS. Of the 10 persons in the control group who were diagnosed as having IBS, 5 were diarrhea-dominant and 5 were constipated-dominant type. Irritable bowel syndrome was more frequent in healthcare professionals than in the control group. Healthcare workers are more prone to IBS due to their stressful working environment.

- Abstract
Background: Widespread use of antibiotics has resulted in increased rates of antibiotic resistance and decreased rates of Helicobacter pylori (H. pylori) eradication, leading to a search for newer therapeutic options. This study aimed to examine the efficacy, tolerability, and patient compliance of a first-line bismuth-containing 5-day concomitant quintuple therapy., Materials and Methods: This prospective study included 144 eradication treatment naïve H. pylori positive patients with dyspeptic complaints. Patients received the following concomitant quintuple therapy for 5 days: bismuth subcitrate 300 mg q.i.d, omeprazole 20 mg b.i.d, clarithromycin 500 mg b.i.d., amoxicillin 1 g b.i.d., and metronidazole 500 mg t.i.d. Eradication was assessed with H. pylori stool antigen test or urea-breath test 6 weeks after the completion of therapy., Results: Treatment compliance rate in this study was 97.2%. Intention to treat and per-protocol eradication rates were 134/144 (93.1%, 95% CI, 88.9-97.2) and 134/140 (95.7%, 95% CI, 92.2-98.6), respectively. Side effect was reported by 8.5% of the patients that attended follow-up visits, including epigastric pain (2.8%), nausea/vomiting (2.1%), diarrhea (1.4%), taste disturbance (1.4%), and fatigue (0.7%)., Conclusions: Bismuth-containing, short course, quintuple concomitant therapy appears to be an effective and safe therapeutic option for the first-line H. pylori eradication, particularly in populations with high resistance., (© 2015 John Wiley & Sons Ltd.)

- Abstract
Objective: Low baseline viremia and an early treatment response predict the best outcomes in hepatitis B virus (HBV)-infected patients treated with nucleoside analogues with low barriers to resistance. The aim of this study was to assess the long-term results and effectiveness of lamivudine in patients with low baseline viremia and early virological treatment response., Methods: In this multicenter, real-life setting study, 111 antiviral-naive patients with low baseline viremia (HBV DNA <10(7) copies/mL) plus an early virological response (HBV DNA <300 copies/mL at week 24) treated with lamivudine were enrolled. The primary end-point was treatment failure, defined as the re-emergence of detectable viremia or at least a 1 log increase in HBV DNA, resulting in a titer of ≥ 300 copies/mL with lamivudine treatment after week 24, which required treatment modification., Results: Altogether 111 patients, including 78 non-cirrhotic and 33 cirrhotic patients, were included in the study. Treatment failure occurred in 30.8% of the non-cirrhotic patients over a median follow-up period of 32.5 months, and the 1-, 2-, 3-, 4- and 5-year treatment failure rates were 6.5%, 14.0%, 31.4%, 39.6% and 43.1%, respectively. Treatment failure occurred in 28.8% of the whole group. There were no differences between the cirrhotic and non-cirrhotic patients., Conclusions: Lamivudine treatment had a high treatment modification rate in patients with low baseline viremia and early virological response over a long-term follow-up in a real-life setting. The pretreatment and on-treatment favorable characteristics found in the studies with telbivudine appeared to be inapplicable to lamivudine., (© 2015 Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine and Wiley Publishing Asia Pty Ltd.)

- Abstract
Objective: To evaluate the endoscopic findings of dyspeptic patients unresponsive to proton pump inhibitors (PPIs) and analyze if there is any correlation between these findings and dyspeptic symptoms via predetermined inquiry., Methods: Patients between 18 and 45 years of age were selected among those referred to our unit for upper GI endoscopy due to failure to achieve improvement in dyspeptic complaints with PPI. Patients who consent to participate in and eligible for the study were questioned for their symptoms using questionnaires., Results: A total of 446 patients with female preponderance (60%) were included in the study. Endoscopic results were listed as: 147 (32.9%) normal, 16 (3.6%) gastric ulcer, 36 (8.1%) duodenal ulcer, 216 (48.4%) gastritis, 7 (1.5%) duodenitis and 24 (5.4%) esophagitis. A total of 122 patients were classified as functional dyspepsia. While incidence of persistent bloating was distinctly higher in patients with gastritis compared to those with normal endoscopic findings (p:0.000), but its incidence was comparable between ulcer and normal patients. No statistical difference was detected between gastritis, ulcer and normal endoscopy patients considering incidence of early satiety. Compared to those with normal endoscopy patients, incidence of epigastric pain was significantly higher among patients with gastritis and ulcer (p: 0.002 and p: 0.000 respectively). Incidence of heartburn was higher in patients with gastritis compared to those with normal endoscopy findings, but it was similar to those with ulcer., Conclusion: Most (67.1%) of the patients between 18 and 45 years of age with no alarm symptoms had diagnoses that required use of a PPI. Hence, the patients should be carefully evaluated before referring for endoscopy., Competing Interests: No conflict of interest was declared by the authors.

- Abstract
Sequential treatment scheme has been developed to overcome resistance problem in H. pylori eradication and favorable results have been obtained. This study compared the results of standard triple therapy with a sequential schema consisting of pantoprazole, amoxicillin, clarithromycin, and metronidazole in a high anti-microbial resistance setting. This retrospective study included subjects that underwent standard or sequential eradication treatment after a diagnosis of biopsy-documented H. pylori infection. Patients either received pantoprazole 40 mg bid, amoxicillin 1000 mg bid and clarithromycin 500 mg bid (PAC) for 10 days, or pantoprazole 40 mg bid and amoxicillin 1000 mg bid (PA) for the first 5 days of the treatment period and were then given pantoprazole 40 mg bid, clarithromycin 500 mg bid, and metronidazole 500 mg bid (PCM) in the remaining 5 days. Eradication was tested using urea breath test. The two treatment groups did not differ with regard to H. pylori eradication rate for both ITT population (63.9% versus 71.4% for standard and sequential therapy respectively, P = 0.278) and per protocol population (65.9% versus 74.1% for standard and sequential therapy respectively, P = 0.248). Although a sequential treatment appears to represent a plausible alternative, our findings suggest that alternative schedules may be required in certain populations to achieve higher success rates.

- Abstract
Background/aims: This study aimed to examine the frequency and type of asymptomatic neurological involvement in inflammatory bowel disease (IBD) using cranial magnetic resonance imaging (MRI)., Methods: Fifty-one IBD patients with no known neurological diseases or symptoms and 30 controls with unspecified headaches without neurological origins were included. Patients and controls underwent cranial MRI assessments for white matter lesions, sinusitis, otitis-mastoiditis, and other brain parenchymal findings., Results: The frequencies of white matter lesions, other brainstem parenchymal lesions, and otitis-mastoiditis were similar in IBD patients and controls (p>0.05), whereas sinusitis was significantly more frequent in IBD patients (56.9% vs 33.3%, p=0.041). However, among those subjects with white matter lesions, the number of such lesions was significantly higher in IBD patients compared to controls (12.75±9.78 vs 3.20±2.90, p<0.05). The incidence of examined pathologies did not differ significantly with disease activity (p>0.05 for all)., Conclusions: The incidence of white matter lesions seemed to be similar in IBD patients and normal healthy individuals, and the lesions detected did not pose any clinical significance. However, long-term clinical follow-up of the lesions is warranted.

- Abstract
Background: Mushroom is widely consumed in Turkey because it is inexpensive and widely available. Intoxication with mushroom is a common health problem in Turkey with a high mortality rate., Aim: To identify the outcome of patients with wild mushroom intoxication who were diagnosed based on systematic criteria and had received a comprehensive treatment., Methods: Seventy-seven patients admitted to the Emergency Department of our hospital with mushroom intoxication were retrospectively evaluated. The patients were administered a combined treatment of gastric lavage, activated charcoal, penicillin G, N-acetyl cysteine, silybin and hemofiltration. Demographic, clinical and laboratory data of patients and the outcomes of the treatment modality were recorded., Results: A total of 77 patients, 46 (59.7%) females and 31 (40.3%) males were evaluated in the study. The mean age of the patients was 41.94 ± 15.40 years. They presented with nausea and vomiting within 4 to 48 hours. Sixteen patients (20.7%) had abdominal pain, six patients had (7.7%) diarrhea and five patients (6.5%) had jaundice. Seven patients (9%) developed acute liver failure and were referred to intensive care units. Five of these patients recovered without any liver transplantation; one patient had cadaveric liver transplantation but died in the early period after the transplantation and one patient died while waiting for transplantation. The rest of the patients were followed by us and they all have recovered., Conclusions: Our data indicate that clinical diagnosis based on systematic criteria and a comprehensive treatment regimen may be effective in decreasing the mortality in mushroom intoxication., (Copyright © 2011 Elsevier Masson SAS.

- Abstract
Background/aims: Endothelial dysfunction is an early and reversible feature in the pathogenesis of atherosclerosis. Coronary flow velocity reserve is a noninvasive test showing endothelial function of epicardial coronary arteries and coronary microcirculatory function. This study was designed to evaluate the carotid intima-media thickness and myocardial microvascular circulation in patients with non-alcoholic fatty liver disease., Materials and Methods: Twenty-four patients with non-alcoholic fatty liver disease and 28 healthy subjects were studied. According to the pathology of liver biopsies, patients with non-alcoholic fatty liver disease were divided into non-alcoholic fatty liver and nonalcoholic steatohepatitis groups. Coronary diastolic peak flow velocities were measured at baseline, and then dipyridamole infusion was measured by transthoracic Doppler echocardiography. The ratio of hyperemic to baseline diastolic peak velocities was calculated and the intima-media thicknesss of the carotid arteries were measured., Results: Baseline average diastolic peak and diastolic mean flow velocities were similar between non-alcoholic fatty liver disease patients and healthy subjects. However, hyperemic average diastolic peak and diastolic mean flow velocities were significantly lower in the patient groups compared to those in the controls (p=0.005 and p=0.002). Coronary flow velocity reserve was 1.65 ± 0.36 and 2.67 ± 0.81 in patients and healthy subjects, respectively (p < 0.001). The intima-media thickness was similar between the patients with non-alcoholic fatty liver disease and healthy subjects. The comparison of patients with non-alcoholic fatty liver and non-alcoholic steatohepatitis within the non-alcoholic fatty liver disease group with respect to coronary flow velocity reserve and intima-media thickness yielded no statistical differences., Conclusions: The present study showed that coronary flow velocity reserve, which establishes coronary microvascular and endothelial functions noninvasively, is significantly impaired in patients with non-alcoholic fatty liver disease. The impaired coronary flow velocity reserve-like early atherosclerotic changes may have value in the prediction of coronary artery disease in patients with non-alcoholic fatty liver disease.

- Abstract
Hepatitis B is an important health problem all over the world as well as in our country. Entecavir is a nucleoside analog used in the treatment of chronic hepatitis B. We present a case of a 55-year-old male patient who developed unilateral gynecomastia while under treatment with entecavir. Physical examination was unremarkable except for minimal hepatomegaly. Laboratory examination revealed: HbsAg: positive, HBeAg: negative, anti-HBe: positive, HBV DNA: 800,000 copies/ml, total anti-HDV: negative, and alanine aminotransferase: 105 U/L (normal range: 0-41). The treatment was started with pegylated interferon. During the follow-up, transaminases did not regress and HBV DNA was found to still be highly positive at the sixth month evaluation. Pegylated interferon treatment was stopped and entecavir was started at a dose of 0.5 mg/day. Six months after the initiation of entecavir treatment, the patient presented with a painful swelling in the right breast. On physical examination, there was painful gynecomastia on the right side, which was confirmed with mammography and ultrasound of the breast tissue. The patient was not taking any drug that may have caused gynecomastia. Hormonal status of the patient was normal. Laboratory values were normal. We considered that this unilateral gynecomastia might be an adverse effect of entecavir. Since the patient had a rapid viral and biochemical response to entecavir, the drug was continued under close follow-up and there was no further progression of the gynecomastia.

- Abstract
Background and Aims: Non-alcoholic fatty liver disease has long been accepted as benign; however, recent evidence suggests that the disease may progress to cirrhosis and hepatocellular carcinoma, although the natural course of the disease is still unclear. This study was designed to comparatively evaluate electron microscopic features of non-alcoholic fatty liver (NAFL) and non-alcoholic steatohepatitis (NASH)., Methods: Quantitative and semi-quantitative ultrastructural evaluations were performed on liver biopsies from 23 patients, 10 with NAFL and 13 with NASH., Results: No statistically significant difference was noted between NAFL and NASH patients in ultrastructural features of hepatocytes including megamitochondria, intramitochondrial crystalline inclusions, mitochondrial matrix granules, foamy cytoplasmic appearance, electron-lucent and glycogen-containing nuclear regions, lipofuscin granules, or an increased frequency of vesicles containing electron-dense material in peribiliary Golgi zone; however, the mitochondrial diameter was significantly higher in the NASH patients. Intercellular distance and microvilli between hepatocytes, collagen and electron-dense material accumulation in the space of Disse, electron-dense material accumulation and microvillus density in bile canaliculi did not differ significantly between the groups., Conclusions: Our data show that, although NAFL and NASH can be distinguished by their distinct light microscopic features, ultrastructural characteristics are similar, which suggests that NAFL may also have the potential to progress to fibrosis and cirrhosis like NASH.

- Abstract
Chemical colitis can occur as a result of accidental contamination of endoscopes or by intentional/accidental administration of enemas containing various chemicals.We present three cases of glutaraldehyde induced colitis and review the cases in the literature. Glutaraldehyde induced colitis presents clinically with severe abdominal pain, bloody and mucoid diarrhea, rectal bleeding, and tenesmus 48-72 h after colonoscopy. Endoscopic findings are nonspecific and mimic ischemic colitis, inflammatory bowel disease, and infectious colitis. The timing of symptoms and the knowledge that glutaraldehyde is a chemical irritant to colonic mucosa is important for the diagnosis. The treatment is mainly supportive but sometimes necessitates mesalamine, prednisolone, or metronidazole and the resolution is rapid. In endoscopy units, strict adherence to published disinfection protocols is very important and the cleaning, rinsing and drying protocols also deserve the same attention., (© Springer Science+Business Media, LLC 2008)

- Abstract
Background: Tumour necrosis factor-alpha (TNF-alpha) plays a central role in inflammatory cascade in Crohn's disease (CD). Our study aims to investigate the in vitro effects of dipyridamole (DP) on the TNF-alpha and interleukin-10 (IL-10) production in the intestinal mononuclear cells of CD patients., Material and Methods: Thirteen patients with CD and in 17 healthy individuals underwent colonoscopy and biopsy samples were taken. Cultured mononuclear cells were preincubated with DP1 (0.7 microg/ml), DP2 (1.25 microg/ml), methotrexate (MTX)1 (0.5 nmol/L) and MTX2 (1.5 nmol/L). These cells were then stimulated with lipopolysaccaride (LPS) and phytohemagglutinin (PHA). The levels of TNF-alpha and IL-10 in supernatants were measured with standard immunoassay monoclonal antibody method., Results: An appropriate cell culture could be obtained in 10 patients with CD and 12 healthy individuals. In LPS stimulated cells, MTX1 and MTX2 were superior to DP1 and DP2 in suppressing TNF-alpha in both groups. In PHA stimulated cells, while MTX1 was superior to DP1, MTX2 and DP2 had an equivalent effect in CD patients (p<0.05, p>0.05, respectively). In LPS-stimulated cells DP2 was significantly superior to MTX2 in increasing IL-10 levels in both groups (p<0.05). In PHA stimulated cells, DP1 and DP2 caused a higher increase in IL-10 levels compared with MTX1 and MTX2 in CD group (p<0.05)., Conclusions: Dipyridamole suppresses TNF-alpha similar with MTX. It seems to be superior to MTX in increasing IL-10 levels. Addition of DP to anti-TNF medications may create a synergy in cytokine modulation.

- Abstract
Abnormal immune response to gliadin, genetic, and environmental factors play a role in the pathogenesis of celiac disease (CD). Non-responsiveness to hepatitis B virus (HBV) vaccination is related to genetic features. Certain human leukocyte antigen (HLA) genotypes are more prevalent among non-responders to HBV vaccination. There is also a strong relationship between CD and these HLA genotypes. This study investigates the relationship between CD and non-responsiveness to HBV vaccination, with an emphasis on genotypic co-incidence. No statistically significant difference was noted between the ages and gender of CD patients and control subjects. Baseline serum IgA, IgM, and IgG levels of all CD patients were normal. Responsiveness to HBV vaccination was observed in 17 (68%) CD patients and all (100%) control subjects (P = 0.006). In conclusion, CD should also be sought in unresponders to HBV vaccine who are not immunosuppressed.

- Abstract
A 24-year-old man with a previous diagnosis of ulcerative pancolitis presented with severe malabsorption with watery diarrhea, malaise, and weight loss. Physical examination revealed paleness, hypotension, tachycardia, edema, ascites, and left-sided pleural effusion. Laboratory analysis revealed hypoalbuminemia and hypocalcemia. Further examination revealed that malabsorption was related to Aeromanas hydrophila infection. Clinical improvement was observed upon oral ciprofloxacin treatment. No clinical or laboratory activation of ulcerative colitis was detected during this infection.
