1.  Mustard gas exposure in Iran–Iraq war – A scientometric study 
Background:
The Iranian victims of sulfur mustard attack are now more than 20 years post-exposure and form a valuable cohort for studying the chronic effects of an exposure to sulfur mustard. Articles on sulfur mustard exposure in Iran–Iraq war were reviewed using three known international databases such as Scopus, Medline, and ISI. The objectives of the study were measurement of the author-wise distribution, year-wise distribution, subject area wise, and assessment of highly cited articles.
Materials and Methods:
We searched three known international databases, Scopus, Medline, and the international statistical institute (ISI), for articles related to mustard gas exposure in Iran–Iraq war, published between 1988 and 2012. The results were analyzed using scientometric methods.
Results:
During the 24 years under examination, about 90 papers were published in the field of mustard gas in Iran–Iraq war. Original article was the most used document type forming 51.4% of all the publications. The number of articles devoted to mustard gas and Iran–Iraq war research increased more than 10-fold, from 1 in 1988 to 11 in 2011. Most of the published articles (45.7%) included clinical and paraclinical investigations of sulfur mustard in Iranian victims. The most highly productive author was Ghanei who occupied the first rank in the number of publications with 20 papers. The affiliation of most of the researchers was Baqiyatallah Medical Sciences University (research center of chemical injuries and dermatology department) in Iran.
Conclusion:
This article has highlighted the quantitative share of Iran in articles on sulfur mustard and lays the groundwork for further research on various aspects of related problems.

2.  Surveillance of acute respiratory infections among outpatients: A pilot study in Isfahan city 
Background:
Considering that there was not any regional survey in Isfahan, Iran regarding the epidemiology of acute respiratory tract infections (ARTI) in different age groups of general population, the aim of this study was to determine the epidemiologic feature of ARTIs in Isfahan using multiplex polymerase chain reaction (PCR) method.
Materials and Methods:
In this cross-sectional study, patients aged <80 years with symptoms of ARTI were studied, during 2009-2010 Nasopharyngeal and dry throat swab specimens were collected and pathogens of ARTI was determined using multiplex real-time PCR.
Results:
In this study, 455 cases with ARTI were studied. Mean age of studied population was 29.9 ± 18.5 (range: 0.2-80). Symptoms such as sore throat (86.3%), coryza (68.0%) and dry cough (54.3%) were the most common symptoms in all studied groups, whereas fever was the most clinical presentation of younger patients (<15 years old) and headache and skeletal pain were the most common symptoms of older patients (>15 years old). Rhinovirus was the most common cause of ARTI in patients aged <5 years and those aged >50 years. Influenza virus B was the most common cause of ARTI in patients aged 5-50 years.
Conclusion:
Our study provides baseline information on the epidemiologic and clinical feature of outpatients with ARTIs in Isfahan city. Though our findings in this pilot study could be helpful in diagnosis, treatment, and prevention of ARTI, planning preventive interventional.

3.  The prevalence of isolated hepatitis B core antibody and its related risk factors among male injected drug users in Isfahan prisons 
Background:
The prevalence of isolated hepatitis B core antibody (anti-HBc) varies between 1% and 30% in different populations. Isolated anti-HBc-positive patients who suffer from occult hepatitis B virus (HBV) infection have the potential to transmit HBV infection. So isolated anti-HBc screening is a valuable tool to prevent HBV transmission. Considering the importance of isolated anti-HBc screening and high prevalence of HBV among injected drug users (IDU) prisoners, we designed this study to evaluate the isolated anti-HBc positivity among inmates with the history of IDU in our area.
Materials and Methods:
We did this cross-sectional study from September 2009 to March 2010 among volunteer male IDU prisoners in Isfahan. Blood samples were taken from all of subjects and tested for HBV markers. Then a questionnaire containing socio-demographic, drug histories and high risk behaviors information was completed for all participants. Data analysis was done utilizing univariate analysis and multiple logistic regressions. A P < 0.05 was considered significant.
Results:
Totally 970 male IDU prisoners (mean age 32.6 ± 8.1) were included in our study. The prevalence of isolated HBc Ab was 4.5%. Isolated anti-HBc significantly was related to tooth filling (OR: 2.62, CI: 1.20-7.14) and imprisonment (OR: 3.95, CI: 1.39-11.18). We couldn’t find any relationship between isolated anti-HBc positivity and addiction duration, incarceration frequency, recent incarceration duration or number of injection per month.
Conclusion:
For screening high risk groups in parallel with hepatitis B surface antigen (HBsAg), hepatitis B surface antibody (HBsAb) and other viral markers, maybe it is better to check HBcAb too, because isolated HBcAb-positive patients may have occult hepatitis B infection which could transfer the infection to others.

5.  Co-infection of human immunodeficiency virus, hepatitis C and hepatitis B virus among injection drug users in Drop in centers 
Background:
Hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV) are the three prevalent viral and bloodborne infections worldwide. Considering the similar route of transmission in these infections, their co-infections would be more challenging for health care professionals. Therefore, we investigated the rate of HIV/HBV/HCV co-infection among injection drug users (IDUs) referred to Drop in centers (DICs).
Materials and Methods:
In this cross-sectional study (2008-2009), IDUs referred to DICs in Isfahan province were evaluated. Venous blood samples were obtained and HBsAg, HBcAb, HCVAb, and HIVAb measured by using enzyme linked immunosorbent assay method. Demographic data and risk factors in patients with HBV/HCV, HIV/HCV, and HIV/HBV co-infections were obtained by a trained social worker using a structured checklist. Data were analyzed using Chi-square test, t-test, and multiple logistic regressions.
Results:
Totally, 539 IDUs with mean (standard deviation [SD]) age of 35.3 (7.9) were studied. HBV/HCV, HCV/HIV, and HBV/HIV co-infections were presented in 65 (12.1%), 6 (1.1%), and 0 (0%) of IDUs, respectively. All HIV infected IDUs were infected with HCV as well. There was a significant association between HBV/HCV co-infection and behaviors related to sharing needle (odds ratio [OR] = 2.06, 95% confidence interval [CI]; 1.23-3.45) and imprisonment (OR = 1.01, 95% CI; 1.04-1.06).
Conclusion:
According to the results of this study, history of imprisonment and needle sharing were the only adjusted risk factors for HCV/HBV co-infection in IDUs. This might be a warning for national health system and needs to urgent paying attention. It seems that expanded harm reduction strategies can be useful to reduce this co-infection and its mortality and morbidity rate among IDUs.

6.  Seroprevalence of hepatitis B markers among incarcerated intravenous drug users 
Background:
Drug injection is one of the most prominent risk factors for transmission of viral hepatitis. Prevalence of hepatitis B virus (HBV) is generally higher in prisoners compared with the general population. The object of this study was to assess the markers of HBV and related risk factors among intravenous drug users (IVDU) in prisoners.
Materials and Methods:
Through a cross-sectional study in 2012 HBV infection and its risk factors were assessed in prisoners with a history of intravenous drug use in Isfahan, Iran. A checklist was fulfilled for each participant and 5 ml blood was taken from each subject. Sera were analyzed for markers of the hepatitis B: Hepatitis B virus surface antigen (HBsAg), antibody to hepatitis B virus surface antigen (HBsAb) and hepatitis B virus core antibody (HBcAb) by ELISA. We used Chi-square test and logistic regression model to analyze data and P < 0.05 was considered to be significant.
Results:
All of the studied participants (n = 970) were men. The mean ± standard deviation of the age of the subjects was 32.61 ± 8.1 years and the majority of them had less than high school education. More than 40% of these men had a history of injection drug inside prison and 2.27% of them self-reported history of HBV infection. Of the 970 IVDU, 32 (3.3%) were positive for HBsAg. Among HBsAg + subjects, 23 (71.88%) were HBcAb+. 120 (12.37%) were found positive for isolated HBsAb, 45 (4.64%) for isolated HBcAb and 67 (6.9%) for both HBsAb and HBcAb. History of sharing needle (odds ratio: 2.25, 95% confidence interval: 1.09-4.65) had a significant association with HBsAg positivity.
Conclusion:
The results suggest that history of sharing needle had a significant association with HBsAg positivity. It seems that educational programs for injecting drug related behaviors, especially syringe sharing, are needed for IVDU.

7.  The assessment of hepatitis B seroprevalence in persons with intravenous drug use history in the Isfahan province: Community-based study 
Background:
Hepatitis B with its complications has become one of the universal problems. Injection drug use is one of the most important risk factors in the transmission of hepatitis B. Therefore, we assessed hepatitis B virus prevalence among cases with a history of intravenous drug use (IVDU) as the first announcement-based study in this regard.
Materials and Methods:
The announcement-based detection of hepatitis B seroprevalence in volunteers with a history of intravenous drug use was conducted in the Isfahan province. A comprehensive community announcement was made in all the public places and to all physicians, in all the regions. One thousand five hundred and eighty-eight volunteers were invited to the Isfahan reference laboratories and serum samples were tested for HBs-Ag, HBc Ab, and HBs-Ab, using the enzyme-linked immunosorbent assay (ELISA) method.
Results:
In this study, 1588 individuals volunteered, who were estimated to be 50% of all the expected intravenous drug users in the community. HBs Ag was detected in 4.2% of them. HBc Ab and HBs Ab were detected in order in 11.4 and 17.3%, respectively.
Conclusion:
We estimated that the seroprevalence of hepatitis B positivity in intravenous drug users was moderate to high. Therefore, it was suggested that this group be encouraged to prevent acquiring infection by vaccination, education, counseling for risk reduction, and treatment of substance abuse, and finally hepatitis B virus (HBV) screening.

8.  Seroprevalence of hepatitis B virus and human immunodeficiency virus among young prisoners 
Background:
Juveniles in custody are affected by sexually transmitted infections due to risky behaviors. Therefore, they have a disproportionate burden of hepatitis B virus (HBV) and human immunodeficiency virus (HIV). In this study, the prevalence and associated characteristics of hepatitis B and HIV infections were assessed in young prisoners.
Materials and Methods:
In this cross-sectional study, prevalence of HBV and HIV infections was assessed among young prisoners during 2008-2009. A checklist consisting of demographic, social, and risk factors was filled out and blood was drawn for their tests. Sera were analyzed for hepatitis B surface antigen (HBs Ag), hepatitis B surface antibody (HBs Ab), hepatitis B core antibody (HBc Ab) and HIV Ab, and Western blot test was performed on antibody-positive HIV.
Results:
A total number of 160 young prisoners (147 boys and 13 girls) were evaluated. The mean age of the subjects was 16.59 ± 1.24 year. HBs Ag, HBc Ab, HBs Ab, and HIV Ab were detected in 1 (0.63%), 1 (0.63%), 52 (32.5%), and 1 (0.63%), respectively.
Conclusion:
With respect to national vaccination program against HBV infection, the juvenile prisoners had low prevalence of HBs Ab.

9.  Prevalence and Risk Factors of HIV, Syphilis, Hepatitis B and C Among Female Prisoners in Isfahan, Iran 
Hepatitis Monthly  2012;12(7):442-447.
Background
Female prisoners are at risk of acquiring sexually transmitted infections (STIs). There has been no previous study regarding the epidemiological status of STIs among female prisoners in Isfahan, central Iran.
Objectives
The aim of this study was to investigate the prevalence and risk factors of the aforementioned infections among women incarcerated in the central prison, Isfahan, to determine appropriate prevention measures.
Patients and Methods
In a cross-sectional study, all of the 163 women incarcerated in the central prison, Isfahan in 2009, were voluntarily enrolled by the census method. After completing a checklist consisting of demographic, social, and risk factors, a 5ml blood sample was taken from each individual. The sera were analyzed for markers of the hepatitis B virus (HBV; HBsAg, HBsAb, HBcAb), hepatitis C virus (HCV; HCV antibodies), human immunodeficiency virus (HIV; HIV antibodies), and syphilis (RPR). Confirmatory tests were performed on HCV antibody-positive cases.
Results
The mean age of the participants in the study was 34.54 ± 11.2 years old, 94.3% of these women were Iranian, and many of them had only a primary level of education. The prevalence of HBsAg, HBcAb, HBsAb, and HCV antibodies were; 1.2%, 7.4%, 12.9% and 7.4% respectively. No positive RPR or HIV antibodies were detected.
Conclusions
A significant relationship was seen between the HCV antibody, drug injection and illegal sex in the women, and also between HBc-Ab and drug injection. Regular screening, educational programs, and facilitation of access to suitable treatment care should be widely implemented in the prison population. Testing for immunity against HBV should be considered on admission, and afterwards vaccination of all prisoners and an appropriate preventative approach should be applied.

10.  Identification of Patients with Hepatitis C Virus Infection in Persons with Background of Intravenous Drug Use: The First Community Announcement-based Study From Iran 
Objectives:
Injection drug use plays the most important role in transmission of hepatitis C. In Iran, surveys have been conducted on various high risk groups but this is the first announcement based study for hepatitis C virus HCV prevalence among cases with history of intravenous drug using (IVDU) in the country.
Methods:
The announcement-based detection and follow-up of patients with anti-HCV positive project in volunteers with history of intravenous drug using was conducted in Isfahan province. At the first step, six focus groups were conducted and 2 pilot studies were carried out in two cities to design the main study. Comprehensive community announcement was done in all of public places and for physicians. The volunteers were invited to Isfahan reference laboratories and the serum samples were sent to Infectious Diseases Research Center Laboratory in standard conditions and HCV-Ab was tested by ELISA method.
Results:
In this study, 1,747 individuals that are estimated 50% of all expected intravenous drug users in the community were presented themselves. The most important reasons of success in recruiting volunteers in this study were the perfect propaganda, appropriate cooperation of lab staffs, continuous evaluation and good cooperation in Isfahan province administrations. HCV-Ab was detected in 34% of them and the HCV-Ab positives were sent for further follow-up procedures including confirmatory test, education, and treatment.
Conclusions:
In spite of some limitations to select real cases, this study was considered as a successful experience. Compared to the surveys in Iran on HCV prevalence in intravenous drug users, the results of this study, which was based on volunteers by announcement seems to be noteworthy.

11.  Hepatitis C among Intravenous Drug Users in Isfahan, Iran: a Study of Seroprevalence and Risk Factors 
Objectives:
Hepatitis C virus (HCV) is one of the major public health problems worldwide which is transmitted through contact with infected blood or blood products. One of the most prevalent modes of HCV transmission is injecting drug with unclean needles or syringes. Therefore intravenous drug users (IVDUs) are the most important group who should be considered. The aim of this study was to evaluate seroprevalence and risk factors of hepatitis C virus in IVDUs population.
Methods:
The cross-sectional study was carried out on intravenous drug users who attended health and social care Drop-in centers during November 2008 to February 2009 in Isfahan province, Iran. Data was gathered using interviewer-administered questionnaire including demographic characteristics and main risk factors for HCV infection. 5ml venous blood sample was obtained from each subject. The HCV-Ab test was performed on all blood samples by ELISA. The data was analyzed using descriptive statistical methods and multiple logistic regressions by SPSS software, version 15.
Results:
The mean age of participants was 31.77 ± 8.51. 503 (94.7%) were men and 28 (5.3%) were women. HCV seroprevalence was 47.1% (95% CI: 42.9, 51.3). The multiple logistic regressions demonstrated that history of tattooing (OR 1.72, 95% CI 1.02-2.90), history of imprisonment (OR 2.49, 95% CI 1.40-4.42) and sharing needles/syringes (OR 2.76, 95% CI 1.54-4.95) are significant predictors of risk of HCV in IVDU population.
Conclusions:
In conclusion, according to the high prevalence of HCV infection among IVDUs and high adds of HCV infection from tattooing, sharing of needles/syringes and imprisonment, effective harm reduction programs should be expanded among IVDUs to prevent new HCV infections.

12.  Prevalence of Anti HCV Infection in Patients with Beta-Thalassemia in Isfahan-Iran 
Objectives:
Hepatitis C virus (HCV) is the major cause of post-transfusion hepatitis infection (PTH). Patients with thalassemia major are at high risk of hepatitis C due to the blood transfusion from donors infected by HCV. The aim of this study was to detect the prevalence of anti-HCV antibodies and risk factors in multitransfused thalassemic patients in Isfahan-Iran to establish more preventive strategies.
Methods:
This study was conducted to assess the patients with beta-thalassemia in Isfahan hospitals during 1996-2011 for HCV infection. A structured interview questionnaire was developed by the trained researcher to collect the demographic and risk factors. Statistical analysis was done by Chi-square test, Mann-Withney and multiple logistic regressions using SPSS software, version 15.
Results:
466 patients with major thalassemia participated in this study. The mean age of patients was 17.46 ± 8.3. Two hundred and seventy (58.3%) and 193 (41.7%) of participants were male and female, respectively. The prevalence of HCV was estimated 8% among thalassemia patients. History of surgery, history of dental procedure, number of units transfused per month, number of transfusion per month and duration of transfusion had significant association with HCV seropositivity in univariate analysis. There were no statistical significant risk factors for HCV seropositivity in multiple logistic regression models.
Conclusions:
Our findings revealed that blood transfusion was the main risk factors for HCV infection among beta-thalassemic patients. Therefore, more blood donor screening programs and effective screening techniques are needed to prevent transmission of HCV infection among beta-thalassemic patients.

13.  Hepatitis C virus infection in patients with hemophilia in Isfahan, Iran 
Objectives:
Patients with hereditary bleeding disorders are at risk of viral infection such as hepatitis C due to frequent transfusion of blood and blood products. This study aimed to determine the prevalence of hepatitis C and associated risk factors in hemophilic patients in Isfahan, the second big province in Iran.
Methods:
In a descriptive study, patients with hemophilia in Isfahan province were enrolled. A questionnaire, including demographic and risk factors of hepatitis C was completed through a structured interview with closed questions by a trained interviewer for each patient and HCV-Ab test results were extracted from patient records.
Results:
In this study, 232 of 350 patients with hemophilia A and B (66%) were positive for hepatitis C. Based on Multivariate Logistic Regression model, no independent risk factor was found.
Conclusions:
Prevalence of hepatitis C in patients with haemophilia A and B in Isfahan is high. Since no independent risk factor for hepatitis C disease was found in this high risk group, it can be concluded that multitransfusion is the only predictor for hepatitis C.

14.  Hepatitis C Virus and Associated Risk Factors among Prison Inmates with History of Drug Injection in Isfahan, Iran 
Objectives:
Hepatitis C virus (HCV) infection is a major public health problem worldwide with serious complications. According to the importance of intravenous drug use (IDU) as the main risk factor for HCV infection and transmission and prison as the main source of risky behaviors, this study conducted to define HCV infection and related risk factors in prison inmates with history of IDU in Isfahan province, Iran.
Methods:
This is a cross –sectional study which the prison inmates with IDU history in voluntary basis were enrolled. A validated questionnaire was asked and blood sample was obtained from each subject for the presence of HCV antibody. Odds ratio and logistic regression were used for data analysis and P-value < 0.05 considered significant.
Results:
I943 inmates with history of IDU participated in the study. The overall prevalence of HCV antibody was 41.6%. The main independent risk factors were number of injection in the month [OR: 1.006 (1.002- 1.011)], Length of drug addiction [OR: 1.05 (1.004-1.098)], multiple incarceration [OR: 1.15 (1.05-1.23)] and use of needle/syringe share inside prison [OR: 4.19 (2.22-7.9)]. In our study, marriage was a protective factor for HCV infection [OR: 0.34 (0.18-0.64)] as well.
Conclusions:
According to relatively high prevalence of HCV infection and associated risk factors which observed in this study it is important to primary prevention in prisons through syringe/needle exchange and counsel with imprisoned IDUs.

15.  Seroprevalence of Hepatitis A in Patients with Chronic Hepatitis C in Isfahan Province 
Objectives:
Patients with Hepatitis C Virus infection are at high risk of getting hepatitis A virus. Hepatitis A virus is an important widespread virus that usually causes more severe medical consequences in patients with chronic liver disease. The purpose of this study was to evaluate prevalence of Hepatitis A Virus antibody in patients with chronic HCV in Isfahan province, Iran.
Methods:
A cross-sectional study was carried out on 117 patients with chronic hepatitis C virus from spring 2010 to spring 2011. Subject's characteristics such as age, gender, education, genotype of HCV infection and history of intravenous drug use were collected by questionnaire and studied. Statistical analysis was done by SPSS software (version 19.0. 2010, SPSS) using Chi-square test, Fisher Exact tests and Cochran-Armitage trend test.
Results:
The mean age of the subjects was 33.18 ± 10.97 years. The seroprevalence of HAV was 94.9% in patients with chronic HCV. The prevalence of anti-HAV increased nearly as age increased. But, there was no statistically significant difference in HAV positive rate according to the age groups (P = 0.242) and other patient's characteristics.
Conclusions:
According to the high HAV immunity in our study and less severe form of HAV infection, vaccination was not required in these patients. However, hepatitis A vaccination program should be performed in HAV seronegative patients with HCV to produce an adequate immune response.

16.  Seroprevalence and Risk Factors of Hepatitis C Virus among Juveniles in Correctional Center in Isfahan, Iran 
Objectives:
Juveniles in custody are affected by blood borne viruses due to high rates of risk behaviors. Therefore, they have a disproportionate burden of infectious diseases, such as hepatitis C virus (HCV) infection. The purpose of the present study was to determine prevalence and associated characteristics of hepatitis C infection in inmates of a correctional center in Isfahan, Iran.
Methods:
We conducted a cross-sectional study of HCV infection in 160 youths, who were admitted to correctional center in Isfahan during 2008-2009. Subjects were asked questions regarding behaviors that might put them at high risk for acquiring HCV and blood was drawn for this test. Sera were analyzed for HCV Ab and RIBA test was performed on antibody-positive HCV. We used Chi-square test and logistic regression model to analyze data and P < 0.05 was considered statistically significant.
Results:
A total of 160 young prisoners (147 boys and 13 girls) were studied. The mean age of the inmates was 16.59 ± 1.24 year. A history of intravenous drug addiction was reported in 3.8% of them. HCV infection was detected in 7 (4.4%) subjects. This study revealed that history of IDU was the main risk factor for HCV (OR, 134.44; 95% confidence interval [CI], 7.29-2481.03).
Conclusions:
To prevent HCV transmission, proper drug prevention educations should be performed in young age prisoners.

17.  Hepatitis D virus infection in Isfahan, central Iran: Prevalence and risk factors among chronic HBV infection cases 
Hepatitis Monthly  2011;11(4):269-272.
Background
Hepatitis D virus (HDV) is dependent on hepatitis B virus (HBV) infection. Acute infection with HDV can occur simultaneously with acute HBV infection or be superimposed onto a chronic HBV infection.
Objectives
This study aimed to identify cases of HDV and determine its prevalence in patients with chronic HBV infection for the first time study in Isfahan, central Iran.
Patients and Methods
In a cross-sectional study in 2009, 346 who had been diagnosed for at least 6 months with chronic HBV were enrolled consecutively. Anti-HDV was measured by ELISA in the serum of these patients.
Results
The study included 245 males (70.8%) and 101 (29.2%) females with a mean age of 39 ± 12.4 years. Anti-HDV was present in 8 (3.5%) HBe antibody-positive patients (p = 0.36) and in 2 (2.3%) HBe antigen-positive cases (p = 0.68). No association was found between hepatitis D and probable risk factors.
Conclusions
This study demonstrates that the prevalence of HDV infection is higher in patients who are positive for HBeAb compared those who are HBeAg-positive. Therefore, most HDV antibody-positive cases in Isfahan are HBV/HDV superinfections but not coinfections.

19.  Prevalence of Hepatitis B Virus Infection in Isfahan Province 
International Journal of Preventive Medicine  2014;5(Suppl 3):S193-S199.
Hepatitis B virus (HBV) is a serious global health problem. It is estimated that 1.5–2.5 million people are suffering from this infection in Iran. A review on HBV infection prevalence in Isfahan, Iran is conducted in this article. It will help researchers for further studies and also will be helpful for control the infection. Medline, Embase, Ovid, Google Scholar, Scientific Information Database, Iranmedex, Magiran and Scientific Journal of Iran Blood Transfusion Organization and also students’ thesis and projects of Isfahan and Kashan universities of medical sciences were searched for key words “HBV,” “HBsAg,” “prevalence,” “Isfahan,” “Esfahan,” and “Kashan in titles and/or abstracts. Overall, 24 articles, including 4, 14, 5 and 1 were assessed in Isfahan province, and Isfahan, Kashan, and Foulad-shahr cities, respectively. The highest and lowest participants were 542705 and 73, respectively. The highest prevalence of HBsAg was reported in HIV-infected patients and the lowest one was seen in the thalassemic patients. We collected the articles about the prevalence of HBV in Isfahan to help researchers and determine prevalence HBV in Isfahan province. The similar studies in other province of Iran are necessary for marking decision.
