Introduction: Infections with hepatitis B and C viruses (HBV and HCV) are a major global health problem. Patients with chronic renal failure (CRF) on hemodialysis constitute a population at risk of HBV and HCV infections. Objective: Determining prevalence of the surface antigen of hepatitis B virus (HBsAg) and antibodies to hepatitis C virus (anti-HCV) in patients who attended dialysis units in the city of Posadas (Argentina). Materials and methods: The studied population comprised 172 patients with CRF in hemodialysis. HBsAg and anti-HCV antibodies were evaluated by enzyme-linked immunosorbent assay (ELISA). Results: On a total of 172 hemodialysis patients included in the study, 98 were males (57%) and 74 were females (43%), aged between 12 and 85 years (mean 53.4). 8.7% (15/172) of the patients were positive for HBsAg and 9.9% (17/172) were positive for anti-HCV reagents. 72.1% of patients had a hemodialysis treatment time of less than 5 years. A history of having received previous transfusions was observed in both HBsAg positive cases (7/15) and the anti-HCV positive cases (5/17). Elevated transaminase levels were observed in patients with positive and negative serology. Conclusion: The results of this study demonstrate a high prevalence of serological markers for HBV and HCV in patients with CRF on hemodialysis in city of Posadas (Argentina), as compared to cities in developed countries.

Introduction. Hemodialysis patients have the highest risk for developing hepatitis B virus (HBV) and hepatitis C virus (HCV) than the general population. There is no study available for HBV and HCV in this population in Somalia. The main objective of this study is to determine the prevalence and risk factors of HBV and HCV infections among hemodialysis patients in Somalia. Methods. A cross-sectional assessment of hemodialysis patients from January 2021 to June 2021 was used in this study. 220 patients were included in this study. Age, sex, duration of hemodialysis, number of hemodialysis sessions per week, history of blood transfusion, HbsAg, and anti-HCV antibodies were examined. Results. Out of the 220 patients, males were predominant (113 (51.4%)). The mean age of the participants was 52.70. The prevalence of HBV was 7.3% (16 respondents), while the prevalence of HCV was 3.2% (7 respondents). 1 respondent (0.5%) had both HBV and HCV. There is a positive correlation between the duration of hemodialysis and the prevalence of HBV and HCV (r(218) = 0.298, p value <0.001), blood transfusion and prevalence of HBV and HCV (r(218) = 0.347, p value <0.001), and the number of hemodialysis sessions per week and prevalence of HBV and HCV (r(218) = 0.402, p value <0.001). The regression model of the combined predictors of history of blood transfusion, duration of hemodialysis, and number of dialysis sessions per week is R2 = 0.25, which indicates a 25% variance in the prevalence of HBV and HCV with a significance of F (3,216) = 23.67, p < 0 .001 . Conclusions. The prevalence of HBV and HCV among hemodialysis patients in this study was 7.3% and 3.2%, respectively. 0.5% of the respondents had both HBV and HCV. History of blood transfusion, duration of hemodialysis, and number of hemodialysis sessions per week appear to have a strong correlation with the prevalence of HBV and HCV.

Background: In limited-resource countries, the prevalence of hepatitis B virus (HBV) infection can be measured using data taken from blood donors. This study aimed to determine the HBV infection seroprevalence and its associated factors among blood donors in Sana’a Governorate, Yemen. Methods: A cross-sectional study was conducted on 500 people who donated blood at hospitals located in Sana’a between August and October 2016. The volunteers were aged 18–65 years old and were recruited using convenience sampling. A set of questionnaires was administered through face-to-face interviews. Blood samples from each donor were tested for hepatitis B surface antigens using enzyme-linked immunosorbent assay. Results: The overall seroprevalence of HBV infection in the blood donors was 2.6%. Participants with a history of dental treatment had 7.80 higher odds (95% confidence interval [CI]: 2.26, 26.71; P = 0.002) for HBV infection. Respectively, blood donors who had history of malaria infection or cupping therapy had 7.48 (95% CI: 1.75, 31.82; P = 0.010) and 7.32 (95% CI: 1.72, 30.83; P = 0.010) greater odds of HBV infection. Conclusion: The seroprevalence of HBV infection in Sana’a is lower than in other governorates in Yemen. Stakeholders could focus on a history of dental procedure, malaria infection and cupping treatment when strategising about HBV infection prevention and control among blood donors.

Abstract Background The risk of hepatitis B virus infection among medical waste handlers who undergo collection, transportation, and disposal of medical wastes in the health institutions is higher due to frequent exposure to contaminated blood and other body fluids. There is limited evidence on the seroprevalence of hepatitis B among medical waste handlers in eastern Ethiopia. The study was aimed at studying the seroprevalence of Hepatitis B Virus and associated risk factors among medical waste collectors at health facilities of eastern Ethiopia. Methods A facility-based cross-sectional study was conducted among randomly selected medical waste collectors from public health facilities in eastern Ethiopia from March to June 2018. A pre-tested and well-structured questionnaire was used to collect data on socio-demographic characteristics and hepatitis B infection risk factors. A2.5ml venous blood was also collected, centrifuged and the serum was analyzed for hepatitis B surface antigen using the instant hepatitis B surface antigen kit. Descriptive summary measures were done. Chi-square and Fisher exact tests were used to assess the risk of association. Multivariate logistic regression was conducted with 95% CI and all value at P-value < 0.05 was declared statistically significant. Results From a total of 260 (97.38%) medical waste collectors participated, HBV was detected in 53 (20.4%) of the participants [95%CI; 15.8, 25.6]. No significant differences were observed in the detection rates of HBV with respect to socio-demographic characteristics. In both bivariate and multivariable logistic regression analysis, being unvaccinated (AOR = 6.35; 95%CI = [2.53–15.96], P = 0.001), history of blood transfusion (receiving) (AOR; 3.54; 95%CI; [1.02–12.24], P = 0.046), history of tattooing (AOR = 2.86; 95%CI = [1.12–7.27], p = 0.03), and history of multiple sexual partner (AOR = 10.28; 95%CI = [4.16–25.38], P = 0.001) remained statistically significantly associated with HBsAg positivity. Conclusion This cross-sectional study identified that HBV infection is high among medical waste collectors in eastern Ethiopia. Immunization and on job health promotion and disease prevention measures should be considered in order to control the risk of HBV infection among medical waste collectors in eastern Ethiopia.

Checkerboard Titration

Hepatitis B virus (HBV) infection is of global public health concern. Among various serological tests used for the diagnosis and screening of HBV infection, the enzyme-linked immunosorbent assay (ELISA) to detect hepatitis B surface antigen (HbsAg) is most widely used. The present study was designed to develop and standardize a cost effective in-house ELISA for the detection of HbsAg and compare its performance with two established commercial kits. The concentrations of coating antibody, conjugates and sera were fixed by checkerboard titration. Using known HBsAg positive and negative sera, four different concentrations (1, 0.5, 0.25 and 0.125 ?g/well) of coating anti-HBs were applied. Similarly, serial dilutions of patients’ sera (1 in 2, 1 in 3, 1 in 5 and 1 in 9) and conjugates (1 in 2, 1 in 3, 1 in 5, 1 in 9 and 1 in 17) were evaluated by checkerboard titration. The optimal concentration of coating antibody was determined at 0.25 ?g/well and 1 in 9 dilution for both conjugates and sera. The performance comparison of our in-house ELISA showed excellent correlation with two commercial kits (Pearson 0.957, P=0.001 for monoclonal antibody coated kit and Pearson 0.929, P=0.000 for polyclonal antibody coated kit) when OD values were compared. All commercial kit proven positive samples was positive while all negative samples were negative with the in-house ELISA resulting in 100% sensitivity and specificity. The results of our study demonstrated that our inhouse ELISA for detection of HBsAg was equally as sensitive and specific as two well-known commercial kits. Thus, this system may be a useful tool for diagnostic and screening purposes, as well as outbreak investigations.

This study was carried out to determine the prevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) markers among adolescents aged between 10 and 16 years old, who are elementary school students in the city of Chapecó, Santa Catarina State, Brazil. The study involved a cross-sectional survey that included 418 volunteers, from March to July, 2008. Serology comprised HBsAg, anti-HBc, anti-HBs and anti-HCV. Tests were performed using automated Microparticle Enzyme Immunosorbant Assay (Abbott, AxSYM System, Wiesbaden, Germany). The prevalence of HBsAg was found to be 0.2% (95%CI: 0.0-1.3), and the prevalence of anti-HBc was found to be 1.4% (95%CI: 0.5-3.1). Regarding anti-HBs, 48.6% had titers greater than 10UI/L. None of the volunteers presented reactive results for anti-HCV. This study showed a low prevalence of HBV and HCV markers of infection and a great number of volunteers immunized against HBV. Finally this study shows the importance of proper health campaigns and policies in reducing those prevalences.
