Abstract
Background & Objectives: To determine the prevalence of HBV infection in the Golestan Province (southeastern part of the Caspian littoral, Iran).
Methods: A single cluster study was conducted in 2005, based on a sample of households, representative of the population aged 25-65 years in Golestan. All participants were invited for face-to-face interviews to gather demographic data. Blood samples were drawn and analyzed for serum markers of HBV infection such as HBsAg and HBcAb by the ELISA method. Factors associated with hepatitis B seroprevalence were analyzed using SPSS13 and STATA /8.
Results: A total of 1850 subjects were screened. The age- & sex-standardized prevalence for HBsAg positivity was 9.7% (95%CI=0.07-0.11). Rates were higher in males than in females (10.8% vs. 8.6%) (OR=1.28 95% CI=0.9-1.7). HBV seroprevalence in unmarried individuals was significantly higher than in those who were married (OR=2.13 95%CI=1.29-3.5). HBsAg(+) status was more frequent in urban areas (OR=1.46 95% CI=0.9-2.3). Thirty-six percent of population was HBcAb positive. HBcAb(+) prevalence was significantly higher in females (OR=1.46 95% CI=1.19-1.8) and married people (OR=1.58 95%CI=1.02-2.45), and also in urban areas (OR=1.34 95% CI=1.09-1.6).
Conclusions: This study shows that the prevalence of HBsAg(+) status in the Iranian province of Golestan is at a level regarded as "high" by the World Health Organization. It is higher than reported by pervious studies in Iran so it is important- especially for health providers and policy makers- to recognize risk factors and design appropriate prevention programs.

Abstract
Background and Objectives: Hepatitis B virus (HBV) infection is a major public health problem worldwide. Islamic Republic of Iran is located in mesoendemic region (prevalence 2%-7%). The aim of this study was to assess prevalence of chronic HBV in Iran according to demographic characteristics.
Methods: Medline, Embase, Science Citation Index Expanded, Ovid, Google Scholar, IranMedex, SID, Magiran and The Scientific Journal of Iran Blood Transfusion Organization (SJIBT) from 2000 till May 2008 were searched. Cross-sectional studies concerning prevalence of hepatitis B infection in Iran were included irrespective of language and date. The outcome of interest was prevalence of chronic HBV infection detected by blood specimen positive for HBsAg.
Results: We icluded 34 studies. The prevalence of chronic HBV infection was estimated about 1.7% or lower in general population 0.8% (95% CI: 0.6%-0.9%) in blood donors and 3.2% (95% CI: 2.3% - 4.1%) in intravenous drug users. Prevalence of chronic HBV infection in beta thalassemic patients varied from zero to 1.5%. Prevalence of chronic HBV infection was higher in middle aged and elders than children, adolescent and youth and was 25% higher in males than females.
Conclusions: Since mass vaccination of hepatitis B in 1993, prevalence of chronic HBV infection has being reduced among children and adolescents. These age groups comprise a large proportion of general population and reduction of HBV infection in this age group may impact on total prevalence of hepatitis B infection, so that now Iran may be considered a hypoendemic region for HBV infection.

Abstract
Background & Objectives: This study was conducted to evaluate the completeness and geographical representativeness of the hepatitis B surveillance system between 2007 and 2013 in Hamadan Province.
Methods: In this descriptive study, all reported cases in Hamadan Province were extracted. The analytical literature review method was used to examine completeness. We used studies on the prevalence and incidence of hepatitis in Iran published between 2007 and 2013. Sensitivity analysis of the results was performed by simulation program using the R software. Geographical representativeness was assessed and plotted by the ArcGIS software, as well.
Results: Totally, 1378 cases were reported to the hepatitis B surveillance system in Hamadan Province. Most cases were from urban areas and were men, married, and housewives mostly in the age group 20 to 29 and 30 to 39 years. Completeness of the hepatitis B surveillance system was 77%. The hepatitis B surveillance system was not representative in terms of occupation but was representative in terms of age, sex, marital status, and place of living.
Conclusion: We concluded that the hepatitis B surveillance system had a relatively good performance. Moreover, findings of the analytical literature review method are affected by the included studies and interpretation of the results should be performed with caution.

Abstract
Background and Objectives: In this regard, in addition to reducing exposure, the most effective way to prevent hepatitis B is vaccination. The coverage of hepatitis B vaccination in the Iranian Health Personnel is reportedly different in various studies and there is not an overall estimate of it. Therefore, the present study was conducted to determine the immune response to hepatitis B vaccine among Iranian Health Personnel using the meta-analysis method.
Methods: This study was a systematic review of the Iranian databases, including Magiran, Iran Medex, IRANDOC, SID, MEDLIB and international databases, including Scopus, PubMed, ScienceDirect and the Google Scholar search engine without any time limit to 2015 using standard Persian and English keywords. Searches were conducted by two researchers independently. Meta-analysis was performed using STATA, version 11.1 to combine data through Random Effects Model.
Results: We evaluated 6311 subjects in 21 studies. The history of injection and complete coverage of hepatitis B vaccination in the Health Personnel was 86.9% (CI: 95%, 83-90.7) and 70.3% (CI: 95%, 65.6-75), respectively. The minimum and maximum vaccination coverage were related to the North (52.7%) and West of Iran (87.2%), respectively.
Conclusion: The coverage of hepatitis B vaccination in Iranian Health Personnel is less than European countries, which requires new management strategies and policies to maximize hepatitis B vaccination in high risk professional groups.

Abstract
Background and Objectives: Hepatitis B virus (HBV) and hepatitis C virus (HCV) co-infections could affect the prognosis of disease in patients with human immunodeficiency virus (HIV)/AIDS. We aimed to determine HBV/HCV co-infection in HIV-positive individuals; and to compare the characteristics of different subgroups of HIV/HBV/HCV.
Methods: In this cross-sectional study, 908 of 2134 newly-registered HIV-positive individuals in the Iranian Ministry of Health in 2016 were recruited. Participants were divided into four subgroups (HBV-/HCV-, HBV+/HCV-, HBV-/HCV+, and HBV+/HCV+). Demographic data and HIV transmission routes were compared between subgroups.
Results: Among908 participants, 505 (60.6%) were HBV-/HCV-, 20 (2.2%) were HBV+/HCV-, 318 (35%) were HBV-/HCV+, and 20 (2.2%) were HBV+/HCV+. Mean age of participants was 36.9 years; 67% were male and 47% were married. The commonest high-risk behaviors were unsafe sex (43.5%) and IV drug-abuse (34.4%). There was no statistically significant difference between the mean ages of subgroups. All HBV+/HCV+ ,92% of HBV-/HCV+, 50% of HBV+/HCV- and 52% of HBV-/HCV- were men and the difference between groups was statistically significant (p-value: <0.001). Seventy four percent of HBV-/HCV+ and 80% of HBV+/HCV+ reported IV drug-abuse. Thirty percent of HBV-/HCV- and 40% of HBV+/HCV- were spouse of HIV-positive or high-risk individuals.
Conclusion: More than 30% of newly registered HIV-positive individuals in the Iranian Ministry of Health in 2016 were co-infected with either HBV or HCV. Frequency of men, marital status and high-risk behaviors were different in various subgroups.

Abstract
Background and Objectives: The prevalence of HBV infection among injection drug users (IDUs) is higher than the general population due to high-risk sexual behaviors and the needle sharing. The aim of this study was to determine the prevalence of HBV infection and its effective factors among IDUs of Kermanshah Province in 2016.
Methods: This ia descriptive-analytic study was performed in 606 male IDUs in Kermanshah Province in 2016. Data were collected through questionnaires and interviews. HBV was also evaluated through blood tests using the rapid test. Simple and multivariate logistic regression analyses were applied to investigate the factors affecting HBV infection. Data were analyzed using STATA-12 software.
Results: The prevalence of positivity HBV antibody was 3% (95% CI: 1.61- 4.32) among male IDUs. According to the results of unit-variable logistic regression analysis, the duration of drug injection (OR = 1.08, 95% CI: 1.02-1.15) and the number of daily injections (OR = 1.38, 95% CI: 1.05-1.81) were risk factors for HBsAg positivity but there were no significant associations in the multivariate regression model.
Conclusion: The prevalence of HBV is much higher among IDUs than in the general population. These populations are at risk for viral infections such as HBV; therefore, it is recommended to provide necessary education about the prevention methods as well as the necessary screening for them.

Abstract
Background and Objectives: Immune deficiency syndrome is an epidemic disease. During immunodeficiency caused by HIV, infections such as tuberculosis, hepatitis B and hepatitis C may occur. Given that the transmission of these infections is similar to that of HIV, the risk of HIV infection with these infections is high. The purpose of this study was to determine the prevalence of common HIV infections and the related risk factors in HIV positive individuals.
Method:This study was conducted as a retrospective cohort study performed on 3047 HIV patients at Imam Khomeini Counseling Center in Tehran who have been admitted in 2004 -2018.Required data were extracted from patient records and entered into Excel software. For data analysis, SPSS version 21 was used.
Results: The mean age of the patients was 44.24 ± 9.46 years and 77.3% of them were male. Of them, 98 (3.2%) were co-infected with hepatitis B, 961 (31.5%) were co-infected with hepatitis C, and 415 (13.6%) were co-infected with tuberculosis. According to the results, hepatitis B and hepatitis C had a significant association with age, marital status, gender, education, prison history, history of injection, history of addiction, and needle sharing.
Conclusion: Due to the common route of HIV transmission and these infections, there is the possibility of co-infection. The demographic variables and behavioral factors are the most effective risk factors for developing co-infections.
