“…The assessment of hepatitis B and C prevalence in different communities, especially among high-risk occupations, has been considered a basic element of public health programs (8, 16). Rates of HBV and HCV infections vary markedly from one country or region to another, and depend on host characteristics and environmental conditions (17, 18).…”

“…The present study would be considered a complementary study to previous ones in Iran and other countries. The prevalence of HBV infection is approximately 2.14% (range 1.3% - 6.3%) across Iran’s provinces, while the prevalence of HCV infection is less than 0.5% in the Iranian general population (8, 15). Our results showed that the prevalence of HBsAg among barbers was about 1.1%, almost the same as in the control group of bakers (1.4%).…”

“…Iran has an intermediate-to-low endemicity for HBV infection (7). A systematic review of HBV infections in Iran revealed that the prevalence is approximately 2.14% (range 1.3% - 6.3%) across the provinces (8), while the rate of HBV carriers varies from 1.7% to 5.4%, with an average of 3.5% (9). So far, chronic hepatitis B remains the cause of more than 50% of cases of cirrhosis and HCC in Iran (10).…”

BackgroundHepatitis B virus (HBV) and hepatitis C virus (HCV) infections are major health problem in the world. Hairdressers (barbers) are in continuous contact with scissors and blades, and are considered a high-risk group for these infections.ObjectivesThe aim of this study was to analyze the prevalence of hepatitis B and C infections in barbers in Tehran and to evaluate their attitudes and knowledge about the occupational risk of these infections.MethodsSix hundred eleven barbers were included in this study. A group of 556 bakers were also selected from the same regions, as a low-risk control group. Serum levels of hepatitis B surface antigen (HBsAg), HBsAg-specific antibody (HBsAb), hepatitis B core antigen-specific antibody (HBcAb), and hepatitis C virus-specific (anti-HCV) antibody markers were measured with the enzyme-linked immunosorbent assay (ELISA). Participants were interviewed using a questionnaire consisting of four sections: demographic information, awareness, behavior, and personal attitudes.ResultsThere were no significant differences in the frequency of HBsAg between the two groups. However, the frequency of HCV Ab in barbers was significantly higher than that in bakers (P < 0.005). In addition, the frequency of HBsAb marker in barbers was significantly correlated with increased awareness (P < 0.05) and number of tattoos (P < 0.001). HBcAb marker was significantly correlated with age (P < 0.001) and duration of professional career (P < 0.005). With age, barbers’ attitudes improved significantly (P < 0.05).ConclusionsBeing a barber alone is not a potential risk factor for HBV infection, while HCV infection is still an occupational health hazards for barbers. We suggest more extensive case-control studies with regard to rates of hepatitis B and C markers among barbers in other Iranian cities to assess the incidence of hepatitis B and C infections among this population.

“…2 Differences also exist for HBV whose primary transmission route of HBV is through sexual contact, parental contact, or mother-to-child transmission. 3 PLHIV co-infected with viral hepatitis demonstrate a two-to five-fold higher mortality risk than non-co-infected patients; moreover, liver diseases in co-infected patients progress more rapidly when compared to those with hepatitis infection alone. 4 China started to encourage voluntary HBV and HCV screening among antiretroviral therapy (ART) patients from 2007.…”

Co-infection with hepatitis B (HBV) and C (HCV) is common among people living with HIV (PLHIV). This study investigates the impacts of hepatitis co-infection on antiretroviral therapy (ART) outcomes and hepatotoxicity in PLHIV. The cohort study included 1984 PLHIV. Hepatotoxicity was defined by elevated alanine aminotransferase (ALT) levels. ART outcomes were measured by CD4 cell counts, viral load, and mortality rate in patients. Among 1984 PLHIV, 184 (9.3%) were co-infected with HBV and 198 (10.0%) with HCV and 54 (2.7%) were co-infected with HBV and HCV. Of these patients, 156 (7.9%) had ALT elevation ≥ grade 1 at baseline. During the course of ART, the mortality rate and its adjusted hazard ratio (AHR) in PLHIV who were co-infected with HCV (2.6/100 person-years [py], AHR = 2.3, 95%CI 1.1-4.7) was higher than for patients with mono-infected HIV, as it was for those with an elevated ALT (4.4/100 py, AHR = 3.8, [1.7-8.2]) at baseline compared to those with normal ALT. After 6-12 months of ART, the incidence of hepatotoxicity among all the patients was 3.7/100 py. The risk of hepatotoxicity was higher in HCV co-infected (18.6/100 py, adjusted odds ratio [AOR] = 12.4, [8.1-18.2]) than HIV mono-infected patients, and for all regimens (nevirapine: 30.0/100 py, 34.2, 7.3-47.9; zidovudine/stavudine: 24.7/100 py, 22.1, 7.1-25.5; efavirenz: 14.5/100 py, 9.4, 3.5-19.2; lopinavir/ritonavir: 40.1/100 py, 52.2, 9.5-88.2) except tenofovir (4.3/100 py, 4.9, 0.8-9.5). Patients with HBV/HCV co-infected had high hepatotoxicity (10.0/100 py, 6.3, 1.2-23.3) over the same period. Patients with HCV co-infection and HBV/HCV co-infection demonstrated higher hepatotoxicity rate compared with HIV mono-infected patients in China.

“…10 Khosravani et al in their study observed mean age as 34.9 years and majority (39.6%) belonging to age group 21-30 years, where as in a study by Ana RC M et al the mean age was 25 years and half the study participants belonged to less than 20 years age group. 14,15 Majority (65.1%) of our participants were females. Female preponderance in our study population could be attributed to the fact that during data collection most of the male members in the house holds was out for work.…”

Background: Hepatitis B continues to pose a tremendous burden of disease with approximately 240 million people having chronic hepatitis B virus (HBV) infection globally. The prevalence of HBV infection varies widely, with rates ranging from 0.1% to 20% in different parts of the world.Methods: This Community based Cross sectional study was carried out for a period of one year (2015-2016) in bock Hajin of Kashmir to find out the seroprevalence of Hepatitis B and various risk factors associated with it.1861 subjects consented and participated in the study. A semi structured, pre tested, self-designed questionnaire was used to gather requisite information. Both screening as well as confirmatory tests were used to find out the seroprevalence of HBsAg in the study population.Results: Out of 1861 participants, 65.1% were females and 34.9% were males. All study participants were Muslims with 64.4% belonging to Sunni sec. 67.3% belonged to age group 10-40 years. Prevalence of hepatitis B infection in the study population was 0.9%. Gender, occupation, education and treatment by quacks were significantly associated with seropositivity. Only 76 (4.1%) of the participants had some knowledge about hepatitis B.Conclusions: The study reveals that the seroprevalence of hepatitis B is very low in the study population. It also reflects a low awareness level of population regarding hepatitis B infection thus demanding timely intervention in the form of awareness campaigns to keep transmission under check.
