Abstract
Primary Sclerosing Cholangitis (PSC) is a chronic cholestatic liver disease which is associated with Inflammatory Bowel Disease (IBD) in 70% of cases. It seems PSC/IBD is a distinct phenotype that is different from PSC, and IBD alone. Hence, we review the epidemiology, pathogenesis, natural course and management of PSC/IBD before and after LT for PSC. Extensive colitis, rectal sparing, backwash ileitis, and mild symptoms are the characteristics of IBD coexisting with PSC. Moreover, PSC patients with concurrent IBD have higher risk of cholangiocarcinoma, and colorectal neoplasia predominantly in right colon and at younger age. Therefore, it is essential to monitor these individuals continuously. It is interesting to note that the course of IBD (ulcerative colitis) after liver transplantation (LT) for PSC varies greatly, and some patients may develop worsening colitis after LT despite immunosuppressive regimens. As well, management of these patients was discussed in this review.

Abstract
The liver plays a principal role in the human body as a metabolic and detoxifying unit. Liver diseases are the world's major health problems and affect millions of people worldwide. Early detection of liver diseases is certainly effective in timely treatment and prevention of their progression. Liver injury is associated with significant alterations in immune responses and pattern changes in various tissue-related gene expressions and cytokine production. Increasing or decreasing the specific spectrum of non-coding RNAs in different phases of liver disease can be a criterion for diagnosis. Novel diagnostic biomarkers are needed for liver diseases. Currently, micro-RNAs (miRNAs) are known to play important roles in the diagnosis of liver diseases. Circulating biomarkers such as miRNA-assisted diagnosis can conceivably be helpful for the early treatment of liver diseases. In this review, we look at miRNAs and their potential applications in liver diseases as diagnostic biomarkers were investigated.

Abstract
Hepatitis B virus (HBV) approximately infects 350 million people. Interleukin-17 (IL-17) as a pro-inflammatory cytokine, have been found to modulate the immune system in infectious and inflammatory diseases. Recently, the influence of genetic changes like single nucleotide polymorphisms (SNP) on expression rate and function of cytokine has been widely investigated. This study was performed to determine any possible association between four IL-17 SNPs (rs2397084, rs763780, rs2275913 and rs10484879) and chronic HBV infection. A total of 466 samples were recruited and studied including 199 chronic patients, 172 healthy controls and 95 spontaneous clearance individuals between genotype and allele frequencies. Genomic DNA was extracted from peripheral blood cells and Polymerase Chain Reaction Restriction Fragment Length Polymorphism (PCR-RFLP) was used to determine the SNPs genotypes. Genotypes frequencies for rs10484879 were 63.8% CC, 31.7% AC, 4.5% AA in chronic group, 54.7% CC, 36.6% AC, 8.7% AA in control and 63.2% CC, 33.7% AC, 5.8% AA in cleared samples. The AC genotype for rs10484879 was significantly associated with a decreased risk of HBV chronicity (Pvalue = 0.031, OR = 2.699, 95%CI: 1.097-6.639). The genotype and allele frequencies of rs2397084, rs763780 and rs2275913 did not show significant difference between chronic HBV patients and healthy controls. Indeed, there is no significant difference between clearance and chronic patient's genotypes in four SNPs. Our results suggest that IL-17A rs10484879 single nucleotide polymorphism genotype is probably associated with susceptibility to HBV chronic infection, while no significant differences in IL-17 rs2397084, rs763780 and rs227591 distribution were found between HBV patients and spontaneous clearance individuals and control participants.

Abstract
AIM To estimate the epidemiological parameters related to the Covid-19 outbreak in Iran. BACKGROUND Estimating the epidemiological parameters of new public health threat (COVID-19) is essential to support and inform public health decision-making in different communities including Iran. METHODS We established a mathematical model to estimate the epidemiological parameters from 19 Feb to 15 March based on daily COVID-19 confirmed cases in Iran. Then, we estimated the effect of early traffic restriction on our estimation. RESULTS We estimated the R0 at 2.11 (95% CI, 1.87-2.50) and the infected number at 92,260 (95% CI: 59,263 -152,212) by 15 March. Our estimate for the ascertainment rate was about 1.2% (95% CI: 1.1-1.4). The latent period estimation was 4.24 (95% CI: 2.84-6.65). We observed a decline in our estimate after considering the traffic restriction. CONCLUSION Our results suggest that health authorities in Iran must take impactful strategies to control the COVID-19 outbreak to reach R0<1. Therefore, the establishment of complementary, multilateral, and cost-effective measures for the treatment of symptomatic and early diagnosis and isolation of asymptomatic cases/contacts are strongly recommended because of low ascertainment rate and large number of infected cases. We additionally recommend that traffic restriction be combined with other controlling measures.

Abstract
Hepatitis B virus (HBV) infection is a major public health concern due to the infection often leads to chronic infection, liver cirrhosis and also liver cancer. The host immune response to HBV infection and also genetic background play significant role in outcome of infection. Single nucleotide polymorphisms (SNPs) are the most important kind of variation in genetic sequences that caused by point mutations. As cytokines have major roles in viral infections, it seems that cytokine gene polymorphisms are independently associated with response to viral infections. Interleukin 21 (IL-21) plays an influential role in both innate and adaptive immune responses. Its specific receptor, IL-21R, produced and located on the surface of T, B and natural killer (NK) cells and is critical for the proliferation and differentiation of these immune effector cells. Many studies confirmed that the IL-21 involved in response to viral infections. We aimed to investigate the association of G/T IL-21 (rs2055979) and C/T IL-21R (rs3093390) gene polymorphisms with chronic hepatitis B virus infection and HBV spontaneous clearance in Iranian population. METHODS In this study, blood samples were gathered from 320 patients with chronic HBV and 310 healthy controls and also 120 HBV spontaneous clearance individuals. Following genomic DNA extraction, genotypes of the selected SNPs determined by PCR and restriction fragment length polymorphism (RFLP) method. The results were analyzed by SPSS software using Chi-square, Logistic Regression, ANOVA and Independent Samples t-Test. RESULTS According to our results, in IL-21R (rs3093390 C/T) gene polymorphism, allele frequency of T is statistically different in the HBV spontaneous clearance group compared to chronic HBV cases. But there is no significant difference between G/T IL-21 (rs2055979) and C/T IL-21R (rs3093390) genotypes distribution in three groups. Also we found that higher serum aspartate transaminase (AST) level in HBV spontaneous clearance group is significantly associated with TT genotype of IL-21 (rs2055979) compared to GG genotype (P value = 0.006). DISCUSSION Our results showed that T allele frequency in IL-21R (rs3093390 C/T) gene polymorphism could consider as a host genetic factor for HBV spontaneous clearance. Probably we can serve it as a potential prognostic genetic marker for spontaneous clearance of HBV infection.

Abstract
AIM In present survey, we attempted to inquire the plausible linkage of rs1327474 A/G and HCV chronic infection or the clearance of the virus. BACKGROUND IFN-γ signaling pathway is an important trigger for activating antiviral immune responses and production of wide variety of molecules with anti-microbial profiles including type 1 cytokines. Any defect or variation in IFNG signaling pathway may result in susceptibility or progression to diverse diseases such as inflammatory and virus associated disorders. Rs1327474 A/G also known as -611 A/G is an important variation which is located in promoter region of Interferon Gamma Receptor-I (IFNGR1) and may have potent risk for HCV susceptibility. METHODS For this purpose, 154 HCV patients and 200 controls were enrolled in the study, and genomic DNA was isolated from PBMCS and IFNGR1 -611 polymorphism was genotyped by polymerase chain reaction- fragments length polymorphism (PCR-RFLP) method. RESULTS While, AA, AG and GG genotypes frequency included 37.8%, 53.7%, 8.5% in healthy controls, 41.6%, 46.1%, 12.3% were found in chronic HCV patients. Interestingly, allelic percentage was similar in both separated groups within 64.7%, 35.3% and 65.3%, 34.7% were obtained for T and G allele in control and case group respectively. CONCLUSION In spite of our exception for the possible role of this variation in an important promoter region of IFGR1 gene, rs1327474 A/G was not associated with HCV chronic infection among an Iranian studied group. Comprehensively, -611A/G cannot be considered as a risk biomarker for susceptibility to chronic HCV disease.

Abstract
AIM The aim of this study was to compare the different phases of chronic Hepatitis B virus (HBV) infection with different values for normal ALT. BACKGROUND For many years, the upper limit of 40 IU was considered normal for ALT for both sexes, but in recent years this value is challenged and some guidelines have lowered their limit. METHODS In this cross-sectional study, 2000 HBsAg positive patients who were referred to Taleghani Hospital, Tehran, Iran, from 2011 through 2018 were classified in four groups according to American Association of the study of the liver disease (AASLD), European Association of the study of the liver (EASL) /Asian-Pacific Association of the study of the liver (APASL) and American Collage of Gastroenterology (ACG) guidelines. The frequency of each group based on 3 different guidelines was compared. RESULTS In HBeAg positive patients (n=100), the percentage of immune tolerance phase was 43% according to AASLD cutoff for normal ALT (35 IU for men, 25 IU for women), while it was 68% and 28% with regard to EASL/APASL and ACG (30 IU for men, 19 IU for women) cutoffs respectively. In HBeAg negative patients (n=1900), 66.68% were inactive carriers according to AASLD, but the percentage changed to 82.89% and 52.42% considering EASL/APASL and ACG values, respectively. CONCLUSION Using ACG and to a lesser extent AASLD cutoff for ALT, many patients shift from immune tolerance and inactive carrier state into the immune active phase. Thus, more patients are candidates for treatment or intensive workup to determine the extent of liver damage.

Abstract
AIM Our goal was to identify the putative association of rs4072111 variant in IL-16 gene and HCV susceptibility in an Iranian population. BACKGROUND Interleukin 16 (IL-16), a multifunctional cytokine, plays a vital role in modulation of immune system. METHODS In present case control and cross sectional study, IL-16 gene variant in 300 patients with hepatitis C (HCV) infection and 300 healthy individuals were analyzed. To evaluate this possible association, genomic DNA from venous blood was extracted and genotypes of IL-16 rs4072111 variant were determined by polymerase chain reaction- Fragments Length Polymorphism Technique (PCR-RFLP). Then, rs4072111 C/T genotypes frequency and allelic distribution were evaluated in each group. RESULTS The results of genotyping showed 82% CC, 17.3% CT, 0.7% TT in the control group and 78% CC, 20% CT and 2% TT in the case group. The distribution of rs4072111 C allele was 90.7% in controls and 88% in case group respectively.However, no correlation between IL-16 rs4072111 C/T variants and susceptibility to chronic HCV infection was found in the present study. CONCLUSION We concluded the rs4072111 C/T cannot be considered as a proper biomarker to identify susceptibility to chronic hepatitis C virus infection.

Abstract
AIM In this study, we investigated the prevalence of PARV4 virus among the healthy population and four other groups of HBV infected, HCV infected, HIV infected and HIV/HCV co-infected individuals in Iran. BACKGROUND Parvovirus 4 (PARV4) was first discovered in 2005, in a hepatitis B virus-infected injecting drug user (IDU). To date, the best evidence about PARV4 transmission is parenteral roots which comes from IDU individuals. It seems that the prevalence of the virus in the normal population is very low. METHODS A total of 613 patients, including chronic HCV (n=103), HBV (n=193), HIV (n=180) infected individuals, HIV/HCV (n=34) co-infected patients and 103 healthy controls, were studied by using nested-PCR and also real-time PCR techniques. RESULTS Of those 180 samples were positive for HIV RNA, co-infection of PARV4 was detected in 3 cases (1.66%). All these three patients were male with the age of 28, 32 and 36 years (mean: 32). No statistical differences were found between HIV positive group and the healthy individuals. (P>0.05) The result of PARV4 PCR was negative in all other samples and healthy controls as well. CONCLUSION This study is the first to investigate the occurrence of PARV4 among these groups in Iran. The results show that the virus is not significant in Iranian population, even in patients with blood born infections such as HCV, HBV or even HIV patients. Further studies in other areas and various groups are required.

Abstract
AIM To determine the distribution of important mutations of the "a" determinant region in the HBV genome among patients in different clinical phases of HBV infection. BACKGROUND Variations in Hepatitis B infection not only change the outcome of the disease but also the symptoms from which the chronic HBV patients are suffering. METHODS We have meticulously selected a total of 40 chronic HBV patients from four different subclasses of chronic HBV clinical phases including immune tolerant (IT), immune active (IA), inactive carrier (IC) and hepatitis B e antigen (HBeAg)-negative (ENEG); 10 samples per each phase. Mutations of the "a" determinant region were identified using PCR-Direct sequencing method. RESULTS 17 amino-acid substitutions at 12 positions inside the "a" determinant were identified in all forty samples; 3 mutations in the IT group, 6 mutations in the IA phase, 3 mutations in the IC patients and 5 mutations in the ENEG phase. Different substitutions were observed in all four clinical phases. The IA phase was the most variant group with the highest number of amino-acid substitutions. CONCLUSION These results did not reveal a strong pattern to distinguish different clinical phases of Chronic HBV infection, but there are some obvious differences regarding the number and position of mutations between these four clinical phases.

Abstract
AIM To assess the possible correlation between single nucleotide polymorphisms (SNPs) of two members of TNF ligand superfamily genes, tumor necrosis factor-α (TNF-α) and lymphotoxin-α (LTA), and HCV chronic disease. BACKGROUND The causes of disease progression from hepatitis C virus (HCV) infection to chronic liver disease still remains unclear. Abnormal production of the cytokines alleged to be contributed to progression of the disease or viral persistence. Regulatory mechanisms that control the production of cytokines including genetic polymorphisms, especially at coding/regulatory regions of genes, may affect expression and secretion of the cytokines. METHODS In this case-control investigation, 258 individuals with serologically proven chronic HCV infection and 277 healthy controls were studied. Genotyping of rs1799964 variant of TNF-α and rs909253 intronic variant in LTA gene were performed. To confirm the results of genotyping, 10% of the specimens analyzed again by sequencing approach. RESULTS In this investigation, a significant association was observed between the TNF-α TC genotype and chronic HCV infection (P = 0.035). Moreover, the frequency of C allele was significantly different between control subjects in comparison with chronic HCV patients (P=0.02). On the other hand, no association was found between LTA gene polymorphism and susceptibility to chronic HCV infection. CONCLUSION These findings indicate that genetic variants like single nucleotide polymorphism in TNF-α rs1799964, could be a host factor associated with susceptibility to HCV chronic infection. However, further large scale investigations are needed to confirm this finding.

Abstract
We investigated innate immune gene expression in clinical phases of chronic hepatitis B infection, including immune tolerant (IT), immune active (IA), inactive carrier (IC) and hepatitis B e antigen (HBeAg)-negative phases, as well as healthy controls. Expression levels of interferon types I, II and III, their receptor subunits, IRFs, TLRs and other IFN-induced genes in peripheral blood mononuclear cells were compared. Forty HBsAg-positive treatment-naïve subjects without co-infection with HIV, HCV or HDV were enrolled. To complement the viral load, the expression levels of 37 innate immune genes were measured by qPCR. The highest response of the innate immune system was observed in the IT and HBeAg-negative phases, and the IC phase had the lowest response; 31 of the 37 studied genes reached their maximum mRNA expression levels in the IT and HBeAg-negative phases, and the minimum expression levels of 23 genes were found in the IC phase. The highest mRNA expression levels of IFNs, IFN receptor subunits, IRFs and TLRs genes in all clinical phases were IFN-λ2 and 3, IFN-γR2, IRF7 and TLR7, and the lowest levels of mRNA expression were observed for IFN-α, IFN-λR1, IRF8 and TLR2. We conclude that innate immune response genes are expressed differentially among chronic HBV phases, and this difference may help to develop new precise and noninvasive methods to determine the progression of disease in chronic HBV patients.

Abstract
AIM The objective of this study was to determine the epidemiologic characteristics of patients with liver cirrhosis. BACKGROUND Liver cirrhosis is an end-stage condition of chronic liver disease. Liver disease is an important cause of morbidity and mortality worldwide. METHODS In this cross-sectional study, demographic and epidemiologic characteristics of 203 patients with liver cirrhosis who were admitted in Taleghani Hospital over a period of two years were determined. RESULTS A total of 203 patients with liver cirrhosis consisted of 136 (67%) males and 67 (33%) females and the mean age was 53.7±15.2 years. No etiology were found in (59.6%) cirrhotic patients; therefore, they were labeled as cryptogenic cirrhosis, but according to clinical evidence and ultrasonography findings, (29.7%) of these patients were probable NAFLD. The other causes of liver cirrhosis in this study were HBV (20.2%), HCV (11.8%) and autoimmune hepatitis (AIH) (8.4%), respectively. Esophageal varices were present in (41.9%), ascites in (36.5%), variceal bleeding in (8.9%), encephalopathy in (7.4%) and spontaneous bacterial peritonitis (SBP) in (5.4%) of patients. When cirrhotic patients were grouped according to Child-Pugh classification, 26.1%, 54.7% and 19.2% were in classes A, B and C respectively. The mean MELD score was 16.16±7.7. CONCLUSION In this study we found that the leading etiology of cirrhosis is cryptogenic cirrhosis 59.6% (in all age groups) and followed by HBV. Noteworthy, according to the clinical and ultrasonography findings, 29.7% of patients who were labeled as cryptogenic cirrhosis were consistent with NAFLD.

Abstract
AIM Chronic Hepatitis C infection is a critical health problem worldwide, which caused by hepatitis C virus (HCV). Interleukin 28B (IL28B) is a determinant factor in disease progression and also susceptibility to chronic HCV infection. BACKGROUND The most significant aim of this study is to analyze the association between IL28B gene polymorphisms with susceptibility to chronic HCV infection in Iranian population. METHODS This study follows a case- control study design, in which, 288 patients with chronic hepatitis C and 250 healthy individuals were genotyped for IL28B polymorphisms (rs12979860 C/T and rs8099917 G/T). Studied population collected from Taleghani Haospital, Tehran. Genotyping of IL28B gene polymorphisms were performed using PCR-Restriction Fragment Length Polymorphism (PCR-RFLP) method. 10 percent of the studied population was sequenced to validate the results. RESULTS rs8099917 G/T and rs12979860 C/T were differently distributed in hepatitis C patients and healthy controls in the female gender. TT, TG and GG genotypes distribution in the female gender were 56.7%, 39.8% and 4.5% in cases and 67%, 31.6% and 1.4% in controls (p=0.54). Also CC, CT and TT genotypes distribution were 31.8%, 61.4% and 6.8% in cases and 51.7%, 44.9% and 3.4% in controls (p=0.2). However, there was no significant difference in the allelic frequency and genotype distribution of rs12979860 C/T and rs8099917 T/G in both HCV patients with genotype 1a and 3a. CONCLUSION It seems that rs8099917 G/T polymorphism plays a significant role in susceptibility to chronic HCV infection in Iranian population. On the other hand, no association was found between rs12979860 C/T polymorphisms and chronic hepatitis C.

Abstract
BACKGROUND Interleukin-16 (IL-16) is an immunomodulatory cytokine, which plays an important role in some inflammatory and autoimmune diseases such as hepatitis B, which is a major health concern worldwide. OBJECTIVES In this study, we aimed to investigate the plausible association between IL-16 polymorphism and chronic HBV susceptibility in an Iranian population. PATIENTS AND METHODS In a case-control study, we analyzed rs1131445 polymorphism in the microRNA binding site of the IL-16 gene in 262 patients with chronic hepatitis B and 269 healthy controls, using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method and DNA sequencing technology to confirm our results. RESULTS Altogether, in this investigation, a significant association was observed between the IL-16 TC genotype compared with the TT genotype (OR = 0.696, 95% CI: 0.485 - 0.997, P = 0.048), after adjustments for confounders including age and gender. CONCLUSIONS These findings show that immunogenetic factors, such as single nucleotide polymorphism in IL-16, could be a risk factor for susceptibility to chronic HBV infection. However, further investigations are needed to verify these results.

Abstract
BACKGROUND According to the reports of World Health Organization (WHO) and Centers for Disease Control and Prevention, the prevalence of chronic hepatitis B infection in Iran has decreased from 2-7% in 2001 to 1.3-0.8% in children aged 2-14 years. In 2010 the Institute of Medicine recommended more comprehensive screening by primary care physicians (PCPs) for evaluation, vaccination, and management of infected patients for further decrease in the prevalence of chronic HBV infection. Thus, with contribution of the Health Department, we developed a practical flowchart for PCPs to start active screening of hepatitis B virus (HBV) in all visited patients and refer the positive cases for further evaluation and management to Taleghani Hospital. METHODS With collaboration of Health Department of Shahid Beheshti University of Medical Sciences), physicians of health centers were asked to screen all their patients for HBsAg. Positive cases were referred to Taleghani Hospital. They were first registered and educated about their disease, life style, and prevention methods. Their first degree families were screened for HBV infection too and were referred for vaccination if needed. According to the results of lab tests, appropriate management was done by a hepatologist. RESULTS Since implementation of this program, we have encountered a significant rise in patient detection (even in high risk groups). Many of them were not aware of their disease and most of those who were aware of their disease were not managed appropriately. Family screening and vaccination were inadequate and need more emphasis. CONCLUSION Although health system is active about screening of HBV infection in high risk populations, it is not perfect. It seems that health system needs to upgrade the screening and management programs of HBV infection.

Abstract
AIM: To review all of epidemiological and etiological aspects of hepatocellular carcinoma (HCC) and examined the prevention of this disease in Asia.
METHODS: We conducted a systematic review according to the PRISMA guidelines. We were chosen articles that published previously, from PubMed (MEDLINE), the Cochrane database and Scopus. The key words used in this research were as follows: HCC in Asia and the way of prevention of this disease, with no language limitations. We selected those papers published before 2014 that we considered to be most important and appropriate. All relevant articles were accessed in full text and all relevant materials was evaluated and reviewed.
RESULTS: More than 70% of all new cases of liver cancer were diagnosed in Asia, a region that 75% of all those chronically infected with hepatitis B virus (HBV) in the world. Chronic HBV infection is the main cause of HCC in Asia, where the virus is endemic and vertical transmission is common. Japan, Saudi Arabia, Egypt and Pakistan are exception because of high prevalence of HCV infection in these regions. The prevalence of this cancer is high in Eastern and South-Eastern Asia, But Middle Eastern countries are characterized as moderate prevalence rate of HCC region and Central Asia and some part of Middle Eastern countries are known as low prevalence rate of HCC. In addition of HBV and HCV the other factors such as aflatoxin, alcohol, obesity, diabetes and non-alcoholic fatty liver disease (NAFLD) might be responsible for a low prevalence of HCC in Asian countries. Currently available HCC therapies, chemotherapy, surgical are inefficient, mainly due to usually late diagnosis and high recurrence rates after surgical resection, and usually end with treatment failure. Liver transplantation also remains as a difficult strategy in patients with HCC. Thus prevention of HCC by treating and prevention HBV and HCV infection, the major causative agents of HCC, and the other risk factors such as aflatoxin, alcohol, obesity, diabetes and NAFLD is of a great medical importance.
CONCLUSION: The main challenge which still present in Asia, is the high prevalence of chronic hepatitis. So, prevention of HBV and HCV is the key strategy to reduce the incidence of HCC in Asia.

Abstract
AIM This retrospective study is aimed to review demographic and clinical characteristics of IBD to elucidate the probable factors associating with IBD development in Taleghani Hospital in Iran since 2001 during a 12-year-period. BACKGROUND Ulcerative colitis (UC) and Crohn's disease (CD) are two major idiopathic entities of inflammatory bowel disease (IBD). Previous studies have reported an increased incidence of IBD in Middle East countries. PATIENTS AND METHODS In the present study 1914 patients with UC, 318 patients with CD and 25 with indeterminate colitis (IC) were included. Demographic information, clinical features, extraintestinal manifestations, complications and extension of disease were collected and interpreted for all participants. According to the time of registration, patients were divided into seven groups. Statistical analysis was performed using the chi-square test. RESULTS In seven groups of IBD patients, disease registry was estimated for UC, CD, and total IBD during a 12-year-period. From 2001 to 2005, a relative increased registry was observed among UC patients. However, in the years 2006 and 2007 a significant reduction in the number of patients was reported. Then an increasing trend was observed in UC patients. UC presented mostly with diarrhea, hematochezia and bloody diarrhea, while most of CD patients complained of abdominal pain. CONCLUSION Evaluation of data related to registered IBD patients in Iran shows that probable incidence and prevalence of IBD (UC and CD) is increasing compared to previous decades.

Abstract
BACKGROUND Chronic hepatitis B is one of the world's major health concerns [corrected]. The etiological agent of this infection is hepatitis B virus (HBV), which can evade the immune system response. Transforming growth factor beta 1 (TGF-β1) can act against HBV by suppressing the viral replication. The TGF-β1 also plays an important role in preventing liver damage in chronically HBV infected patients. OBJECTIVES In this study, the association of TGF-β1 +915G/C and -509C/T gene polymorphisms with chronic hepatitis B was evaluated in Iranian patients. MATERIALS AND METHODS A population-based case-control study was conducted in Taleghani Hospital, Tehran. A number of 220 patients with chronic hepatitis B and the same number of healthy control subjects were designated the case and the control groups. The PCR-Restriction Fragment Length Polymorphism Method (PCR-RFLP) method was used for genotyping both polymorphisms. Ten percent of the control samples were sequenced to confirm the results. RESULTS No statically significant differences in genotype distribution and allele frequency were observed for both polymorphisms between healthy controls and patients with chronic hepatitis B. CONCLUSIONS There was no association between TGF-β1 -509C/T and +915G/C polymorphisms with chronic hepatitis B and it seems that these changes do not play a significant role in increasing the risk of chronic infection in Iranian patients [corrected].

Abstract
Background: Liver injury or dysfunction is considered as a serious health problem. The available synthetic drugs to treat liver disorders are expensive and cause further damage. Hence, hepatoprotective effects of some herbal drugs have been investigated, and one of the methods to choose herbs in order to study their biological effects is to search in ancient medical texts. Avicenna who is known as the prince of physicians had collected and classified Greek, Persian and Islamic medicine in the best possible way in the book of Canon in Arabic. Objectives: Avicenna’s book of The Canon of Medicine was reviewed to find the hepatoprotective herbs. Patients and Methods: Three different versions of the Canon were prepared and utilized. To find scientific names of plants we took advantage of three botany references. All of the herbs were investigated on the basis of scientific data from hepatoprotective effects point of view. The searched term was “hepatoprotective” without narrowing and limiting. The searched databases included Cochrane library, Web of science, SID, Irandoc and IranMedex. Results: 18 plants were found. 85% of the presented species, genus or families of plants were reported to have hepatoprotective properties and in the remaining 15% there were no reports of hepatoprotective effect. Flowers and fruits were the most used part of the plants. Most of the plants had simultaneous protective effects on multiple organs but the protective effect on the liver was mostly accompanied by protective effect on the stomach (83%). The average temperament of these herbs is "hot" in the 2nd phase of the 2nd grade, and "dry" in the 3rd phase of the 2nd grade. Hepatoprotective herbs mostly prescribed as a part of hepatoprotective compound drugs formula or other formula for liver diseases are Crocus sativus, Pistacia lentiscus, and Cinnamomum spp. Conclusions: Maybe there is common mechanism for protecting both liver and stomach. Aquilaria agallocha, Aquilaria malaccensis, and Ruscus aculeatus whose hepatoprotective effects have not yet been reported are considered as good candidates for future investigations. Given that Crocus sativus, and Cinnamomum spp are used as flavors in most countries, they will be introduced for more investigation in order to produce hepatoprotective drugs.

Abstract
AIM The aim of this study was to determine the prevalence of HDV infection between HBV chronic patients referred to gastroenterology ward of Taleghani hospital Tehran, Iran and also investigating the risk factors in acquiring the HDV infection. BACKGROUND Hepatitis B virus (HBV) and Hepatitis D virus (HDV) are major public health issues. Worldwide there are approximately 350 million individuals chronically infected with the HBV. A significant part of them, including 15 to 20 million coinfected with HDV. Hepatitis Delta virus is transferred mostly through blood and body fluids. PATIENTS AND METHODS HBV and HDV infections were evaluated by Enzyme-linked immunosorbent assay (ELISA). Liver functional tests were assessed through auto analyzer. Patients were interviewed and data along the test results were entered into SPSS program. We used chi-square, independent t-test and logistic regression for statistical analysis. RESULTS 278 (54.6%) patients of the study group were male and 231 (45.4%) were female and the mean age of patients was 40.03 ± 14.93. From 509 patients, 39(7.7%) had anti-HDV antibody. In a uni-variable analysis, age (p=0.001), periodontal procedures (p=0.015), endoscopy (p=0.024) and colonoscopy (p=0.012) were significantly related to HDV seropositivity. After adjustment by logistic regression, age remained the only significant factor in acquiring HDV infection. CONCLUSION We highly recommend the health care workers to strictly follow the disinfection protocols of medical instruments. Since HDV seroprevalence changes over time, regular epidemiological studies are necessary to monitor the epidemiological trend of infection.

Abstract
AIM This study was designed to evaluate the frequency of antibody against these viruses in individuals attending the endoscopy ward of Taleghani hospital Tehran, Iran. BACKGROUND Blood-borne viruses such as hepatitis B and hepatitis C virus and HTLV-1 virus are among the world's public health problems. Hepatitis viruses cause liver problems and HTLV-1 infection can lead to adult T-Cell lymphoma (ATL). PATIENTS AND METHODS Blood samples of 219 individuals attending the endoscopy ward of Taleghani hospital between years 2009-2011 were collected. A questionnaire containing demographic data was completed for each subject. Blood samples were tested for antibody against HTLV-1, HCV and HBc by ELISA (Dia.pro Italy). In case of positive results for anti-HBc, samples were also tested for HBs Ag antigen. RESULTS Ninety two subjects were male and 127 were female. Mean age of the population was 39.87 ± 16.47. None of the subjects had anti-HCV antibody, while 4 of them had anti-HTLV-1 antibody and 26 anti-HBc antibody; which only two of these individuals had HBs Antibody. CONCLUSION The results of this study show that frequency of anti-HCV and anti-HTLV-1 antibodies are very low, while the frequency of anti-HBc was higher in the population. Since HTLV-1 is the causative agent of a type of blood cancer, it seems that screening of donated bloods in this region should be considered.

Abstract
BACKGROUND Co-infection with hepatitis C virus (HCV) and/or human immunodeficiency virus (HIV) in patients with chronic hepatitis B virus (HBV) infection can alter the course of the disease. OBJECTIVES In this study, we investigated the frequency of HIV and/or HCV co-infection in chronic HBV patients and related risk factors in acquiring the HCV and or HIV co-infectionit. PATIENTS AND METHODS We studied 264 chronic HBV patients who visited the Gastrointestinal and Liver Ward of the Taleghani Hospital, Tehran, Iran between 2006 and 2010. Demographic information and records of possible risky behavior were obtained. Antibodies against HBV, HCV, and HIV, levels of alanine transaminase (ALT) and aspartate transaminase (AST), and conversion from hepatitis B e antigen (HBeAg) to hepatitis B e antibody (HBeAb) were evaluated. RESULTS Of 264 patients with chronic HBV in this study, 184 patients (70%) were men and 78 patients (30%) were women. Only 1 patient (0.37%) was positive for anti-HIV antibody, whereas 12 patients (4.54%) were positive for anti-HCV antibody. None of the patients had co-infection with all 3 viruses (HBV, HIV, and HCV). CONCLUSIONS This study demonstrated that the prevalence of HCV is higher than that of HIV in chronic HBV patients. Since HCV or HIV co-infection affects the therapeutic outcome in chronic HBV patients, testing for HIV and HCV is recommended, especially for patients with a history of risky behavior.

Abstract
OBJECTIVE The purpose of this study was to provide the first national estimate on the prevalence of the metabolic syndrome and its components and the first ethnic-specific cutoff point for waist circumference in the Eastern Mediterranean Region. RESEARCH DESIGN AND METHODS This national survey was conducted in 2007 on 3,024 Iranians aged 25-64 years living in urban and rural areas of all 30 provinces in Iran. The metabolic syndrome was defined by different criteria, namely the definition of the National Cholesterol Education Program (NCEP) Adult Treatment Panel III (ATP III), the International Diabetes Federation (IDF) criteria, and the modified definition of the NCEP/ATP III (ATP III/American Heart Association [AHA]/National Heart, Lung, and Blood Institute [NHLBI]). RESULTS The age-standardized prevalence of the metabolic syndrome was about 34.7% (95% CI 33.1-36.2) based on the ATP III criteria, 37.4% (35.9-39.0%) based on the IDF definition, and 41.6% (40.1-43.2%) based on the ATP III/AHA/NHLBI criteria. By all definitions, the prevalence of the metabolic syndrome was higher in women, in urban areas, and in the 55- to 64-year age-group compared with the prevalence in men, in rural areas, and in other age-groups, respectively. The metabolic syndrome was estimated to affect >11 million Iranians. The optimal cutoff point of waist circumference for predicting at least two other components of the metabolic syndrome as defined by the IDF was 89 cm for men and 91 cm for women. CONCLUSIONS The high prevalence of the metabolic syndrome with its considerable burden on the middle-aged population mandates the implementation of national policies for its prevention, notably by tackling obesity. The waist circumference cutoff points obtained can be used in the region.

Abstract
Baker's asthma is one of the most common forms of occupational asthma. This study was conducted to determine prevalence of asthma and rhinitis among bakery workers in the city of Sanandaj, the provincial center of Kurdistan province in the west of Iran in the in Summer 2006. In this study 776 bread bakery workers were included. These subjects were selected randomly among 1620 bakery workers. The diagnosis of asthma was based on a medical history of episodic symptoms of cough, chest tightness, and dyspnea and spirometry. Airflow obstruction was determined with spirometry, the definition of airflow obstruction which was used in this study was an FEV1/FVC ratio < 0.8, and FEV1 or FVC increases of > or = 12 percent and at least 200 mL after using a short-acting inhaled beta2-agonist. Rhinitis was diagnosed by typical history of work related symptoms. Analyses were performed on 776 subjects (all were men) without missing data for asthma and rhinitis. All of subjects were male with mean age of 33.69+/-11.09 years. Mean duration of bakery working for these subjects was 13.91+/-9.37 years. Prevalence of asthma at the time of study was 11.9%. 93 subjects were diagnosed as asthma with history, physical and spirometry findings. 31 (33.3%) of asthmatic workers were diagnosed as asthma previously and 62 (66.6%) workers were known as new asthmatic patients which were diagnosed in this study program. The prevalence of rhinitis was (9.9%). Subjects with asthma had longer history of working at bakery than others (P=0.001). Asthma prevalence among these bakery workers that were included in our study was similar and in some instances the prevalence was lower than other studies.

Abstract
AIM: To evaluate the frequency, clinical and paraclinical features of hepatopulmonary syndrome (HPS) and to determine their predictive values in diagnosis of this syndrome in patients in Iran.
METHODS: Fifty four cirrhotic patients underwent contrast enhanced echocardiography to detect intrapulmonary and intracardiac shunts by two cardiologists. Arterial blood oxygen, O2 gradient (A-a) and orthodoxy were measured by arterial blood gas (ABG) test. The patients positive for diagnostic criteria of HPS were defined as clinical HPS cases and those manifesting the intrapulmonary arterial dilation but no other criteria (arterial blood hypoxemia) were defined as lHPS cases. HPS frequency, sensitivity, positive and negative predictive values of clinical and paraclinical features were studied.
RESULTS: Ten (18.5%) and seven (13%) cases had clinical and subclinical HPS, respectively. The most common etiology was hepatitis B. Dyspnea (100%) and cyanosis (90%) were the most prevalent clinical features. Dyspnea and clubbing were the most sensitive and specific clinical features respectively. No significant relationship was found between HPS and splenomegaly, ascites, edema, jaundice, oliguria, and collateral veins. HPS was more prevalent in hepatitis B. PaO2 < 70 and arterial-alveolar gradient had the highest sensitivity in HPS patients. Orthodoxy specificity was 100%.
CONCLUSION: Clubbing with positive predictive value (PPV) of 75% and dyspnea with negative predictive value (NPV) of 75% are the best clinical factors in diagnosis of HPS syndrome. PaO2 < 70 and P (A-a) O2 > 30 and their sum, are the most valuable negative and positive predictive values in HPS patients.

Abstract
This study examined the effects of chronic ethanol feeding and acute ethanol exposure in vitro on biotin transport in rat intestine. Transport studies were performed with intestinal everted sacs. Ethanol was fed to rats for 6-7 wk. Compared with pair-fed controls, ethanol feeding significantly decreased plasma biotin concentrations and transport at physiological concentrations (0.01, 0.1, and 0.3 mumol/L) but not at pharmacological concentration (100 mumol/L). When added to the incubation medium of everted jejunal sacs from dry-food-fed rats, ethanol (2% vol:vol) significantly inhibited the transport of biotin at a physiological concentration (0.1 mumol/L) but not at a pharmacological concentration (100 mumol/L). The inhibitory effect of ethanol on the transport of 0.1 mumol biotin/L increased with increasing concentration of ethanol in the incubation medium [0.5% to 5% (vol:vol)]. Acetaldehyde, the major ethanol metabolite, also significantly inhibited biotin transport at 0.2% (vol:vol). These data demonstrate that chronic ethanol feeding and acute ethanol exposure in vitro inhibit the intestinal transport of biotin by the carrier-mediated process. Chronic ethanol feeding is also associated with a significant decrease in plasma biotin concentrations. The ethanol-induced inhibition in intestinal transport of biotin may be a contributing factor in reducing plasma biotin concentrations.

Abstract
Unlike adult rats, which transport biotin preferentially in the jejunum of the small intestine, suckling rats transport biotin preferentially in the ileum. The characteristics and kinetics of the transport process of biotin in the ileum of developing suckling rats and the subsequent maturation of the process in weanling and adult rats are not known and, therefore, are examined in this study. Transport studies were performed in suckling (16-d-old), weanling (25- to 27-d-old), and adult (90-d-old) rats using the everted sac technique. Transport of biotin in the ileum of suckling rats was significantly higher (p less than 0.01) than that in weanling rats, and transport in weanling rats was in turn significantly higher (p less than 0.01) than that in adult rats. In all age groups examined, transport of biotin was found to be Na(+)-dependent and saturable as a function of concentration within the physiologic range (less than 10 microM), but linear at high concentrations. However, the Vmax of the carrier-mediated transport system of biotin showed progressive decrease with maturation (3290 +/- 363, 829 +/- 47, and 463 +/- 19 pmol/g tissue wet wt/15 min in suckling, weanling, and adult rats, respectively), whereas no significant changes were observed in the apparent Km (2.8 +/- 0.6, 2.6 +/- 0.4, and 3.4 +/- 0.4 microM in suckling, weanling, and adult rats, respectively). These findings suggest that maturation is associated with a decrease in the number (and/or activity) but not the affinity of the ileal biotin transport carriers. Transport of biotin by the diffusion process was also found to decrease with maturation (diffusion rates of 144, 86.5, and 40 pmol/g tissue wt/15 min were found for suckling, weanling, and adult rats, respectively).(ABSTRACT TRUNCATED AT 250 WORDS)
