Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is one of the important causes of mortality due to malignancy. Toll-like receptors (TLRs) are very important in liver pathophysiology in terms of their roles in the innate immune system, such as the regulation of inflammation, wound healing, stimulation of adaptive immune responses, promotion of epithelial regeneration, and carcinogenesis. In this study, we planned to examine the role of TLR1 (rs4833095, rs5743551) and nucleotide-binding oligomerization domain (NOD2) (rs2066844, rs2066845, rs2066847) polymorphisms in the development of HCC and their effects on the clinical presentation of HCC patients. METHODS Our study was designed prospectively. Cirrhotic and HCC patients who were followed up in our clinic between January 2015 and September 2018 were included in the study. Sex, age, cirrhosis etiology, Child-Pugh class, and MELD scores were recorded. TLR1 and NOD2 polymorphisms were studied by the PCR method. RESULTS HCC developed in 88 (31.4%) of the 280 patients who were followed up, either during the recruitment phase of our study or during the follow-up. The mean follow-up time of our patient group was 17.04 ± 11.72 months, and the mean follow-up time of HCC patients was 12.09 ± 10.26 months. TLR1 (rs5743551) polymorphism was associated with HCC development (P = .003). TLR1 (rs5743551) and NOD2 (rs2066844) polymorphisms were associated with the development of spontaneous bacterial peritonitis (SBP) in the HCC patient group (P = .013 and P = .021, respectively). CONCLUSION We think that increased bacterial translocation in cirrhotic patients may contribute to HCC development by causing chronic inflammation, especially in patients with TLR 1 (rs5743551) polymorphism.

Abstract
BACKGROUND Predominant molecules in Peganum harmala leaves were detected using gas chromatography-mass spectrometry (GC-MS). Based on the results of this analysis, most alkaloids, flavonoids and triterpenoids in found P. harmala was compiled from the literature in order to develop and lead the production of effective inhibitor drugs for ACE2, main protease, and RNA dependent RNA polymerase (RdRp) proteins of SARS-CoV-2 virus, which is today's most contagious and deadly disease. AIM By comparing FDA-approved drugs used in the treatment of COVID-19, we aimed to determine whether the molecules in P. harmala are effective against SARS CoV-2 in silico. RESULTS AND CONCLUSION P. harmala molecules were selected as drug candidates from the PubChem web tool. Afterwards, molecular docking calculations of these inhibitor molecules were made with Maestro Molecular modeling program by Schrödinger. The comparison of molecules with high inhibitory activities with FDA-approved drugs was made. With molecular mechanics Poisson-Boltzmann surface area (MM-PBSA) calculations, docking calculations of molecules that have high inhibitory activity, were tried to be verified by calculations in the range of 0-100 nanoseconds (Tab. 4, Fig. 6, Ref. 53).

Abstract
BACKGROUND It is the SARS-CoV-2 virus, one of the most significant diseases of today's world. Due to the high transmission of this disease, studies are ongoing to discover an inhibitor drug that can stop this disease. In this study, inhibitory drugs used for many diseases were tried to stop the SARS-CoV-2 virus. AIM In the calculations made, inhibitor molecules for the SARS-CoV-2 virus were calculated by molecular docking method. RESULTS AND CONCLUSION Inhibitory activities of SARS-CoV-2 virus against spike glycoprotein (PDB ID: 6M0J, 6LZG), main protease (PDB ID: 5RGG, 6WTT), and RNA dependent RNA polymerase (RdRp) (PDB ID: 6YYT, 7BV2) proteins were compared. Then, docking calculations were supported by calculations by MM-PSBA of the inhibitor with the highest activity. Afterwards, it was compared with FDA approved drugs for the SARS-CoV-2 virus. It was found that the Carvedilol molecule was the best against RNA dependent RNA polymerase (RdRp) protein of SARS-CoV-2 (Tab. 4, Fig. 9, Ref. 42).

Abstract
BACKGROUND SARS-CoV-2, which started in Wuhan and later affected the whole world, is the most important disease of the world today. Many ways to inhibit SARS-CoV-2 virus are sought to prevent the spread of this virus. Azithromycin and clarithromycin are considered for the treatment of the SARS-CoV-2 virus, which has a high similarity to previous colonic diseases. AIM We aimed to determine whether azithromycin and clarithromycin, the RNA-dependent RNA polymerase protein inhibitor used in the treatment of COVID-19, is effective against SARS Cov-2 in silico. RESULTS AND CONCLUSION The 503 analogues of azithromycin and clarithromycin were studied to target SARS-CoV-2 the RNA-dependent RNA polymerase protein inhibition. Maestro program was used to compare the inhibition activities of these analogues. A detailed comparison was made using the numerical value of many parameters obtained. ADME / T properties were then examined to determine the effects and reactions of analogues on human metabolism. In this study, the SARS-CoV2 virus is 6NUR and 6NUS, which is the RNA-dependent RNA polymerase protein. Among these proteins, the best inhibitor among the 503 analogues according to the docking score parameter was 9851445 with a great difference. This analogue was an analogue of azithromycin (Tab. 3, Fig. 6, Ref. 58).

Abstract
Objective: There has been no previous study comparing the frequency of sicca symptoms and Sjögren's syndrome (SS) in coeliac patients (CPs) and healthy controls (HCs) using a tight screening method. The aim of this study was to compare the frequency of sicca symptoms and SS in HCs and CPs.Method: The study included 80 CPs and 100 HCs. This study was designed as a case-control study with four phases. The frequency of SS in CPs and HCs was defined according to the 2002 American-European Consensus Group (AECG) and 2012 American College of Rheumatology (ACR) classification criteria. The frequency of sicca symptoms and SS was compared between CPs and HCs.Results: Ocular and oral symptoms occurred in 22% and 26% of CPs, respectively, compared to 13% and 10% of HCs, respectively. Proportions with oral symptoms were statistically significantly different between CPs and HCs (p = 0.005), whereas there was no significant difference for ocular symptoms (p = 0.113). According to ACR and AECG criteria, the prevalence of SS was 3.8% and 5.0% in CPs and 3.0% and 2.0% in HCs, respectively.Conclusion: Although oral symptoms were more frequent in CPs than in HCs, the frequency of SS was not different between the groups. The increased frequency of oral symptoms may be related to reasons other than autoimmunity.

Abstract
BACKGROUND/AIMS Hepatorenal syndrome (HRS) is a severe complication of advanced cirrhosis and is characterized by renal dysfunction and poor survival rates. Although anemia is a non-rare condition in advanced liver cirrhosis, there is no publication regarding the potential or additive effects of anemia on HRS and renal dysfunction in patients with cirrhosis. We investigated whether severe anemia is a precipitant factor for HRS. MATERIALS AND METHODS In this prospective study, consecutive patients with cirrhosis with and without renal dysfunction were enrolled. A total of 29 patients with cirrhosis with HRS meeting the HRS diagnostic criteria (9 patients with type 1 HRS and 20 with type 2 HRS) and 37 patients with cirrhosis without HRS were included. The demographic features, laboratory data (particularly anemic parameters), and clinical scores of patients with and without HRS were evaluated. RESULTS Grades of ascites, Child-Turcotte-Pugh (CTP) scores, and Model of End Stage Liver Disease (MELD) scores were significantly higher in contrast to hemoglobin levels; hematocrit concentrations were significantly lower in patients with type 1 and 2 HRS than in those with non-HRS stable cirrhosis. There was a negative correlation between the hemoglobin-hematocrit and serum creatinine levels. In the logistic regression analysis, the hemoglobin levels and CTP and MELD scores were statistically significant for an onset of HRS. CONCLUSION Anemia may contribute to HRS and deteriorated renal function in patients with HRS because anemic hypoxia can lead to microcirculatory renal ischemia in the kidneys and anemia can also activate sympathetic activity and hyperdynamic circulation in the pathogenesis of HRS.

Abstract
BACKGROUND/AIM Albumin is the most important protein synthesized by the liver. Posttranscriptional changes occur in the molecular structure of albumin due to various factors and isoforms arise. Ischemic modified albumin (IMA) is one such isoform. This study was conducted to evaluate serum IMA concentrations in patients with hepatitis B virus (HBV)-related chronic liver diseases. MATERIALS AND METHODS This study included 74 treatment-naive chronic hepatitis B patients, 25 patients with HBV-related cirrhosis, and 49 healthy controls. Serum IMA concentration was measured spectrophotometrically using the albumin cobalt binding test. RESULTS The mean IMA concentrations in the chronic hepatitis B group and healthy controls were 0.33 ± 0.11 ABSU and 0.27 ± 0.70 ABSU, respectively, and the difference was statistically significant (P < 0.001). Mean IMA/albumin ratios (IMAR) in the chronic hepatitis B and control groups were 0.08 ± 0.04 and 0.06 ± 0.17, respectively, and the difference was also statistically significant (P < 0.001). Higher serum IMA concentrations and IMAR were detected in patients with advanced fibrosis. CONCLUSION Serum IMA concentration and IMAR are increased in patients with HBV-related chronic liver diseases and IMA and IMAR are associated with the degree of liver fibrosis. IMA and IMAR may have potential use as noninvasive markers of fibrosis in chronic hepatitis B patients.

Abstract
OBJECTIVE Obstetric anal sphincter injuries are one of the most significant complications of vaginal delivery that give way to fecal incontinence, which is defined as the involuntary leakage of gas, fluid or solid stool. Although sphincter injuries are seen in 0.5-9% of all deliveries. It has been reported that 20-41% of women who had vaginal deliveries had occult anal sphincter injuries as endoanal ultrasonography began to be used by physicians. The aim of our study was to investigate the relationship between fecal incontinence, whose incidence increases dramatically during the postmenopausal stage, and occult anal sphincter injuries. MATERIALS AND METHODS Two hundred healthy female patients with no history of anal sphincter injury, aged between 18 and 70 years were included in the study. The participants were divided into 4 groups according to their menopausal stages and mode of delivery; premenopausal (group 1) and postmenopausal (group 2) vaginal delivery, and premenopausal (group 3) and postmenopausal (group 4) cesarean section. Wexner incontinence scores were determined. The participants' defects were assessed using endoanal ultrasound and their status of fecal incontinence using anorectal manometric measurements. RESULTS Anorectal manometric measurement results were found significantly lower in group 1 than in group 3 (p<0.01). The Wexner scores of groups 1 and 3 were similar. The anorectal manometric measurement results of group 2 were significantly lower than those of group 4, and the Wexner score of group 2 was significantly higher than other groups (p=0.03). CONCLUSION Anal sphincter injuries formed after vaginal delivery may be one of the reasons that increase the incidence of postmenopausal fecal incontinence and cause the formation of fecal incontinence symptoms in women.

Abstract
BACKGROUND/AIMS Acute kidney injury (AKI) is frequent in cirrhotic patients and is associated with a poor prognosis. Recently, the Kidney Disease: Improving Global Outcomes (KDIGO) organization recommended new criteria for the diagnosis and staging for AKI. The aim of this study was to evaluate the presence of AKI according to KDIGO criteria in cirrhotic patients admitted to the hospital and to determine its association with hospital mortality. MATERIALS AND METHODS This retrospective study included 277 cirrhotic patients admitted to the intensive care unit and gastroenterology service of a tertiary referral hospital from January 2008 to January 2012. AKI was diagnosed and classified according to the KDIGO criteria. RESULTS The overall incidence of AKI in cirrhotic patients was 39%, and the overall hospital mortality was 15.5%. Patients without AKI had a hospital mortality rate of 2.4%, whereas the mortality rate for patients with AKI was 36.1%. The peak AKI stage detected during hospitalization was stage 1 for 58 patients (53.7%), stage 2 for 20 patients (18.5%), and stage 3 for 30 patients (27.7%). Mortality was found to be associated with the presence, stage, and progression of AKI. Multivariate analysis showed that AKI was an independent factor significantly associated with mortality (odds ratio: 9.1; 95% confidence interval: 2.89-29.1; p<0.001). CONCLUSION KDIGO criteria can be used to evaluate AKI in cirrhotic patients. The prevalence of AKI in patients with cirrhosis is high, and AKI is associated with mortality. If early preventive measures are taken, it may be possible to prevent AKI progression and thus mortality.

Abstract
BACKGROUND/AIM Acute pancreatitis is the most common adverse event of endoscopic retrograde cholangiopancreatography (ERCP). We aimed to evaluate the efficacy of intramuscular diclofenac sodium for prophylaxis of post-ERCP pancreatitis (PEP) in comparison to the rectal form. MATERIALS AND METHODS One hundred and fifty consecutive patients who underwent ERCP were enrolled in this single-center, prospective, randomized controlled study. Patients were randomized into three groups. The first group received 75 mg of diclofenac sodium via intramuscular route and the second group received 100 mg of diclofenac sodium rectally 30-90 min before the procedure. The third group served as the control group. Patients were evaluated for post-ERCP pancreatitis with serum amylase levels and abdominal pain 24 h after the procedure. RESULTS The overall incidence of PEP was 6% (n = 9) and 2% (n = 1) in the intramuscular (IM) and rectal groups, respectively, and 14% in the control group (P = 0.014). Nineteen (12.7%) patients developed post-ERCP abdominal pain (8% in IM, 10% in rectal, and 20% in control group; P = 0.154). Twenty-five (16.6%) patients developed post-ERCP hyperamylasemia (10% in IM, 12% in rectal, and 24% in control group; P = 0.03). CONCLUSION Prophylaxis with diclofenac given rectally or intramuscularly is an effective option for the management of post-ERCP pancreatitis.

Abstract
BACKGROUND/AIM The aim of this study is to establish follow-up protocols for adult patients with common variable immunodeficiency (CVID) in a recently founded adult immunology clinic in the Central Anatolia Region of Turkey, where a clinical immunology center for adults was not available previously. MATERIALS AND METHODS A total of 25 patients with CVID aged 18 years and older were included in this study. The file format consisted of 13 pages and was developed for the purpose of the study. Separate sections were designated for identity information, medical history, disease course, previous and current laboratory and imaging studies, follow-up plans, detection and management of complications/comorbidities, and treatment results. RESULTS The mean age of the patients was 36.6 ± 13.4 years. The delay in diagnosis was 107 ± 95.6 months. In 92% of patients, initial symptoms resulting in admission to healthcare facilities were infections. Seventeen of 25 patients (68%) had bronchiectasis at the beginning of follow-up. CONCLUSION Early identification of complications and comorbidities in patients with CVID will significantly improve quality of life and survival. Close observation and standardized protocols for follow-up are essential components of management.

Abstract
Liver hydatid cysts are known to rupture into the biliary tree, but acute pancreatitis is a rare complication of intra-biliary rupture. Intra-biliary rupture was first reported in 1928 by Dew. Intra-biliary rupture is a serious complication of hepatic hydatid cysts. The incidence varies from 1% to 25% in adult patients. In our case, we aimed to show the migration of the material of a hepatic hydatid cyst to the common bile duct and the impaction of hydatid membrane in the papillary orifice, which may cause acute pancreatitis. Parasitic infections should be considered as a differential diagnosis in patients with acute biliary pancreatitis.

Abstract
BACKGROUND Familial Mediterranean fever is an auto-inflammatory disorder. Long term complications of the disease include decreased quality of life. The measurement of quality of life in the patients with chronic disease has become an important research topic during the last years. AIM We aimed to evaluate life quality of the FMF patients by SF-36, and examine its relationship with the disease parameters. PATIENTS AND METHODS One hundred voluntary patients (69 female, 31 male) admitted to the rheumatology clinic were included in the study. The control group consisted of 100 healthy individuals. All subjects in the study were asked to complete SF-36 questionnaire. Age of onset of FMF, age at diagnosis, age at the beginning of colchicine therapy, number of attacks per month, family history of FMF and dialysis were inquired of patients with FMF. Disease severity was determined using the FMF severity score. RESULTS The mean age of the patient group was 31±12 and that of the control group was 29±9. Sixty-nine patients (69%) were female, and 31 patients were male (31%) in both groups. The mean scores of the physical function, physical role function, emotional role function, mental health, and general health parameters of the patients were statistically significantly lower than those of healthy volunteers (p < 0.05). The difference in social function and vitality between two groups was found to be insignificant (p > 0.05). CONCLUSIONS We have shown that FMF had a negative impact on SF-36. FMF reduces quality of life both in physical and mental dimensions.

Abstract
Alström syndrome is a rare autosomal recessive genetic disorder characterized by cone-rod dystrophy, hearing loss, childhood truncal obesity, insulin resistance and hyperinsulinemia, type 2 diabetes, hypertriglyceridemia, short stature in adulthood, cardiomyopathy, and progressive pulmonary, hepatic, and renal dysfunction. Alström syndrome is a very rare cause of liver cirrhosis. Postmortem biopsies of patients with Alström syndrome show relevant fibrosis in multiple organs especially in the liver, kidneys, heart, and lungs. We report the case of a patient with Alström syndrome who presented to emergency department with esophageal variceal bleeding and who was not known to have hepatic cirrhosis before.

Abstract
BACKGROUND & AIMS Data are limited on the efficacy and safety of tenofovir and entecavir when given for more than 1 year to patients with hepatitis B-related cirrhosis. We investigated the long-term safety and efficacy of these antiviral drugs in patients with chronic hepatitis B virus (HBV) infection, with compensated or decompensated cirrhosis, and compared results with those from lamivudine. METHODS We performed a retrospective analysis of data from 227 adult patients with chronic HBV infection who were diagnosed with cirrhosis, beginning in 2005, at 18 centers throughout Turkey. There were 104 patients who had decompensated cirrhosis, and 197 patients were treatment naive before. Seventy-two patients received tenofovir (followed up for 21.4 ± 9.7 mo), 77 patients received entecavir (followed up for 24.0 ± 13.3 mo), and 74 patients received lamivudine (followed up for 36.5 ± 24.1 mo). We collected data on patient demographics and baseline characteristics. Laboratory test results, clinical outcomes, and drug-related adverse events were compared among groups. RESULTS Levels of HBV DNA less than 400 copies/mL were achieved in 91.5%, 92.5%, and 77% of patients receiving tenofovir, entecavir, or lamivudine, respectively. Levels of alanine aminotransferase normalized in 86.8%, 92.1%, and 71.8% of patients who received tenofovir, entecavir, and lamivudine, respectively. Child-Turcotte-Pugh scores increased among 8.5% of patients who received tenofovir, 15.6% who received entecavir, and 27.4% who received lamivudine. Frequencies of complications from cirrhosis, including hepatic encephalopathy, variceal bleeding, hepatocellular carcinoma, and mortality, were similar among groups. Lamivudine had to be changed to another drug for 32.4% of the patients. CONCLUSIONS Tenofovir and entecavir are effective and safe for long-term use in patients with compensated or decompensated cirrhosis from HBV infection.

Abstract
Chanarin-Dorfman syndrome (CDS) is an autosomal recessive neutral lipid storage disease. It is very rare and characterized by ichtiosis, intracellular fat droplets in leucocytes (Jordan anomaly) and involvement of multiple tissues (skeletal muscle, central nervous system, bone marrow, eye and ear) mainly the liver. Our patients were diagnosed as CDS because they had ichtiosis, Jordon anomaly of leucocytes in peripheral blood smear, liver involvement and presence of homozygous 88 insertion C frame shift mutation on exon 4 of ABHD5/CGI-58 gene in genetic analysis. Our cases were two sisters. One of them developed severe steatohepatitis on age 19 and the other one was diagnosed as decompensated cirrhosis when she was 26 years old. We report here a new mutation in comparative gene identification-58 (CGI-58) gene causing syndactyly and steatohepatitis induced early cirrhosis.

Abstract
OBJECTIVE Heterotopic gastric mucosa (HGM) is found in the cervical oesophagus, just below the upper oesophageal sphincter, and has generally been overlooked by endoscopists. The objective of the present study is to determine endoscopic prevalence and histopathological and clinical characteristics of HGM and to classify patients according to their clinicopathological features. METHOD A total of 911 consecutive patients (436 M and 475 F) who were admitted to our Endoscopy Unit were examined. HGM type and the presence of Helicobacter pylori (Hp) either in the stomach or in the HGM were histopathologically evaluated. RESULTS Of the 911 patients, 33 (25 M and 8 F) were found to have HGM. HGM prevalence was determined to be 3.6%. On the basis of HGM patients' symptoms, only dysphagia was significantly correlated with the size of HGM (p < 0.05). Hp was positive in 29.2% of HGM. Clinicopathological classification of the patients showed that 20 patients were HGM type 1 and 13 were HGM type 2. None of the patients had HGM type 3, 4 or 5. CONCLUSION Prevalence of HGM was 3.6%. Dysphagia was found related with the size of HGM. This may be associated with larger HGMs' causing more acid secretion.

Abstract
We describe a 65-year-old man who had liver involvement with Churg-Strauss syndrome. He was admitted to the hospital because of fever, weight loss, dyspnea, abdominal pain, skin lesions and paraesthesias. His past medical history revealed a diagnosis of acalculous cholecystitis that had been made eight months earlier. Microscopic examination of a gall bladder biopsy specimen obtained at that time revealed an increase in extravascular eosinophils. There was evidence of a new bilateral pulmonary disease with bronchoconstriction and a transient infiltrated lesion in the right upper lung. The patient's white cell count was 14 620 per cubic millimetre, with 39% eosinophils (5800 per cubic millimetre) and 39% neutrophils. IgE was 503 g/L (normal range, 0 to 100 g/L). Liver function tests were mildly elevated. Fine needle liver biopsy showed active interface hepatitis. A diagnosis of Churg-Strauss syndrome was made. In this patient the syndrome occurred in a rare association with hepatitis, likely due to immunologic events in the liver. The patient was successfully treated with 60 mg/day of prednisolone monotherapy.

Abstract
Fasciola hepatica is an endemic parasite in Turkey. Chronic Fasciola hepatica infestation is known to cause biliary obstruction and inflammation. Also, biliary fasciolosis may be asymptomatic. We report three patients with biliary fasciolosis who were diagnosed and managed by endoscopic retrograde cholangiopancreatography (ERCP). None of cases had eosinophilia. All cases were admitted to hospital with nonspecific symptoms. ERCP may be used for direct diagnosis and management of biliary fasciolosis.

Abstract
We sought to evaluate the effects of pentoxifylline (PTX) on steatohepatitis in a novel experimental nonalcoholic steatohepatitis (NASH) model induced by a high-fat diet (HFD). Thirty-three male Sprague-Dawley rats were randomly divided into 3 groups. The first group received only standard rat diet (control group); groups 2 (placebo group) and 3 were given HFD, ad libitum. After week 4, 0.5 mL of physiologic serum was injected subcutaneously to the placebo group and 50 mg/kg/d PTX was given intraperitoneally to the third group (group PTX). After 6 weeks all rats were humanely killed. Serum biochemistry, tumor necrosis factor-alpha (TNF-alpha), plasma, and liver tissue malondialdehyde (MDA) were analyzed. Histopathologically, steatosis, ballooning degeneration, inflammation, and fibrosis were determined. Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels, plasma and liver tissue MDA, and plasma TNF-alpha levels were significantly higher in placebo group than in the control group. Tumor growth factor-beta levels, however, were comparable in the placebo and control groups. On histopathologic examination, steatosis, inflammatory cells per square millimeter, and ballooning degeneration were significantly higher in the placebo group than in the control group. No fibrosis or Mallory bodies were found in the placebo group. AST, ALT, plasma and liver tissue MDA, and plasma TNF-alpha levels were significantly lower in PTX group compared to the placebo group. Histopathologically, steatosis, mean number of inflammatory cells/mm(2) and ballooning degeneration in PTX group were also significantly lower than in the placebo group. In conclusion, PTX strikingly ameliorates steatohepatitis in this novel NASH model not only by inhibiting the TNF-alpha but also suppressing the oxidative stress markers.

Abstract
Fasciola hepatica (FH) can lead to important hepatobiliary diseases. Here we present a case of hemobilia associated with biliary FH, which is quite a rare case. The 41-year-old patient, who underwent common bile duct exploration due to hemobilia, was found to have arterial bleeding associated with ulcer caused by a dead parasite in the common bile duct. Hemobilia is a very rare complication associated with FH. When searching for the cause of hemobilia, FH should be considered.

Abstract
In this study we investigated TNF-alpha and leptin levels in two different liver fibrosis models induced by carbon tetrachloride (CCl(4)) and common bile duct ligation (CBDL). A total of 36 male rats of Albino-Wistar strain were allocated to three groups. One of the groups was the control. The second group received 0.15 ml 100 g(-1) CCl(4) subcutaneously for 6 weeks, 3 days per week. The third group underwent common bile duct ligation (CBDL) and was monitored for 4 weeks. Histopathological investigation included fibrosis, steatosis and inflammation. Serum IL-6 and TNF-alpha levels were analysed by ELISA methods and leptin was analysed by RIA. Fibrosis and steatosis increased significantly in the CCl(4) group in comparison with the CBDL group (p < 0.01; p < 0.001). Leptin and TNF-alpha levels in CCl(4) group were higher than those in the CBDL and control groups (p < 0.05). TNF-alpha and leptin levels were not related to each another in either the CCl(4) group or the CBDL group (r=0.22, p > 0.05; r=0.19, p > 0.05). The IL-6 level was higher in the CCl(4) group in relation to severity of inflammation (p < 0.05). TNF-alpha and leptin levels were higher in animals with liver fibrosis induced by CCl(4), than they were in those whose liver fibrosis was induced by common bile duct ligation. Leptin and TNF-alpha may be less effective on the development of liver fibrosis in the group which underwent common bile duct ligation.

Abstract
BACKGROUND & AIMS Liver biopsy is the gold standard for the diagnosis of non-alcoholic steatohepatitis (NASH), but is an invasive method. There is a need for non-invasive methods that can reflect the histopathological severity of NASH. The aim of this study was to compare the ultrasonography and computerized tomography findings with the histopathological severity in patients with NASH. MATERIAL AND METHODS Twenty-two consecutive patients with biopsy proven NASH and 20 age- and sex-matched healthy individuals were enrolled. Clinical and demographic data were collected at the time of liver biopsy. Histopathological grading and staging were made by an expert pathologist. Each patient underwent ultrasonography and computerized tomography. RESULTS Liver ultrasonographic findings were not correlated with histopathological grade and stage (r: 0.134, P > 0.05; r: 0.130, P > 0.05). Mean liver densities obtained by computed tomography of NASH patients were lower than that of controls (P < 0.05) and liver/spleen density ratios were lower than that of controls (P < 0.05). These results were significantly correlated with histopathological grade (r: -0.716, P < 0.001; r: -0.663, P: 0.001), but not with the histopathologic stage (r: -0.416, P: 0.05; r: -0.356, P: 0.1). CONCLUSIONS Ultrasonography findings do not reflect histopathological severity in patients with NASH. Computed tomography attenuation of the liver is significantly correlated with histopathologic grade but not with histopathological stage.

Abstract
The aims of our study were to estimate serum levels of malondialdehyde (MDA), serum levels of vitamin A and alpha-tocopherol as antioxidants and determine relationship of these with histopathologic severity in patients with non-alcoholic steatohepatitis (NASH). Twenty-nine patients with biopsy-proven NASH were included to study. NASH were histopathologically scored for grading and staging. Serum MDA and vitamin A levels were increased in patients with NASH and simple steatosis as compared to healthy control group. Serum alpha-tocopherol levels measured in simple steatosis and NASH were significantly lower than in healthy control group. There was no significant difference between grade/stage 0-1 and grade/stage 2-3 in terms of MDA, vitamin A and alpha-tocopherol levels. Serum MDA and vitamin A levels are increased in simple steatosis and NASH. MDA, vitamin A and alpha-tocopherol levels in NASH were not associated with the histopathologic severity.

Abstract
Fulminant hepatitis is a rare complication of acute hepatitis A infection. Nevertheless, the seroepidemiology of the infection is rapidly changing with the developing world, rendering more adults susceptible to the infection, in particular with more severe course. We report here fulminant hepatitis A infection with a mortal course during an epidemic period in two siblings. Although it causes a self-limited mild disease, hepatitis A virus may have a severe course including fulminant hepatitis and may lead to mortality, especially in older ages. Hence, the risk of hepatitis A virus infection and its complications should be reduced with measures of immunization and sanitation.
