INTRODUCTION: Vaccination is the main tool for preventing hepatitis B virus (HBV) infection; however, following the completion of the vaccination series, the concentrations of anti-HBs can decline over the years and reach levels less than 10mIU/mL. The persistence of protection in these individuals is still unknown. The present study aimed to determine the anti-HBs antibody levels among children and adolescents who had received a complete vaccination course for hepatitis B. METHODS: Antibodies against HBV surface antigen (anti-HBs) were tested in 371 individuals aged 10 to 15 years-old. RESULTS: Volunteers who showed undetectable quantities of anti-HBs accounted for 10.2% of the population studied and 39.9% presented antibody titers of less than 10mIU/mL. Anti-HBs ≥ 10mIU/mL were verified in 49.9%. CONCLUSIONS: These results corroborate other studies indicating levels of anti-HBs below 10mIU/mL in vaccinated individuals. Additional studies are required to assess whether this indicates susceptibility to HBV infection and the need and age for booster doses.

Aims: The study was carried out among 120 dentists working in the selected hospitals of Dhaka city to find out the preventive practice on hepatitis B virus (HBV) infection. Methods: A descriptive type of cross-sectional study was carried out involving 120 dentists working in the selected hospitals of Dhaka city from December 2011 to March 2012 to quantify the preventive practice on HBV infection through a pretested semi-structured questionnaire. Results were analyzed by using the software SPSS 16.0 version (Chicago). Then analyzed data were presented according to the variables of the study showing percentage relationship between variables using appropriate statistical method.Results: Mean age of the dentists was 26.43±6.29 (range, 25-45) years where 74.17% were male and 25.83% were female. Among 120 respondents, 20.83% obtained BDS degree along with a postgraduate training (PGT) in any of the respective fields of dentistry. Others obtained MS in dentistry (21.67%), MPH in dentistry (10.83%), PhD in dentistry (9.17%), DDS in dental surgery (10%) and FCPS in dentistry (6.67%). Academic positions of the respondents were 33.33%, assistant professors, 26.67% associate professors, 19.17% medical officers, and 17.5% were lecturers. Majority (93.3%) dentists knew about HBV transmission, prevention, symptoms, risks, and concurrences. Out of them, 87.5% reported having been tested for HBV which was associated with their designations (p=0.013) and more than 75% reported having been vaccinated against HBV. Conclusions: A high level of knowledge and attitude towards practice in the prevention of HBV was found to be very good among the dentists of Dhaka city though seemed it was not always possible to take precaution for handling emergency patients. Further broad scale studies would be needed to have decisive results. DOI: http://dx.doi.org/10.3329/cdcj.v10i1.13831 City Dent. Coll. J Volume-10, Number-1, January-2013

Abstract Background: Hepatitis B virus (HBV) infection is hyper-endemic in Nigeria. Prisons are high-risk environments for the spread of blood-borne and sexually transmitted infections. Prevalence of HBV infection is disproportionately higher among individuals in correctional facilities worldwide when compared to general population. We determined the seroprevalence and risk factors associated with HBV infection among Kuje prison inmates, Nigeria.Methods: We conducted a prison facility based cross-sectional study. Interviewer administered questionnaires were used to obtain information on participants socio-demographic characteristics, HBV risk factors, previous HBV test and vaccination history. Blood samples collected from participants were analysed for HBsAg, HBsAb, HBcAb, HBeAg and HBeAb markers using rapid lateral chromatographic immunoassay kit. Univariate, bivariate, and multivariate analysis were performed.Results: A total of 271 inmates (63 convicts and 208 awaiting trial inmates) were recruited into the study as participants. The mean age of the participants was 32.7 SD±9 years. HBV sero-prevalence of 13.7%(95%CI;9.8-18.3) was found. 55.4%(95%CI;49.2-61.4) of inmates were susceptible to HBV infection, 20.7% (95%CI;16.0-26.0) had past or resolved HBV infection while 10.3%(95%CI; 7.0-14.6) had acquired natural or artificial HBV immunity. Factors found to be associated with HBV infection include age-group ≤25years (aOR=8.0;95%CI:2.9-22.3), being ever married (aOR=4.2;95%CI:1.7-10.4) and history of alcohol consumption (aOR=3.4; 95%CI:1.3-8.4).Conclusion: This study reveals a high seroprevalence of HBV infection among Kuje Prison inmates, hence the need to introduce prison-focused health intervention initiatives such as HBV screening, vaccination and care to reduce the transmission of HBV infection among inmates and ultimately the general population.

Introduction Hepatitis B virus (HBV) infection is hyper-endemic in Nigeria. Prisons are high-risk environments for the spread of infectious diseases. Worldwide, seroprevalence of HBV infection is substantially higher among individuals in correctional facilities when compared to general population. We determined the seroprevalence and risk factors associated with HBV infection among Kuje prison inmates, Nigeria. Material and methods We conducted a prison facility based cross-sectional study. Interviewer administered questionnaires were used to obtain information on participants socio-demographic characteristics, HBV risk factors, previous HBV test and vaccination history. Blood samples collected from participants were analysed for HBsAg, HBsAb, HBcAb, HBeAg and HBeAb markers using rapid lateral chromatographic immunoassay kit. Univariate, bivariate, and multivariate analysis were performed. Results A total of 271 inmates (63 convicts and 208 awaiting trial inmates) were recruited into the study as participants. The mean age of the participants was 32.7 SD±9 years. HBV seroprevalence (HBsAg) of 13.7% (95% CI: 9.8–18.3) was found. 55.4% (95% CI: 49.2–61.4) of inmates were susceptible to HBV infection, 20.7% (95%CI; 16.0–26.0) had past HBV infection while 10.3% (95% CI: 7.0–14.6) had acquired natural or artificial HBV immunity. Factors found to be associated with current HBV infection (HBsAg) include age-group ≤25years (aOR = 8.0,95% CI: 2.9–22.3), being ever married (aOR = 4.2, 95% CI: 1.7–10.4) and history of alcohol consumption (aOR = 3.4, 95% CI: 1.3–8.4). Conclusion This study reveals a high seroprevalence of HBV infection among Kuje Prison inmates, hence the need to introduce prison-focused health intervention initiatives such as HBV screening, vaccination and care to reduce the transmission of HBV infection among inmates and ultimately the general population.

Abstract Background Despite the development of a safe and efficacious hepatitis B vaccine in 1982, the hepatitis B virus (HBV) remains a public health burden in sub-Saharan Africa. Due to shared risk factors for virus acquisition, men who have sex with men (MSM) and transgender women (TGW) living with HIV are at increased risk of HBV. We estimated the prevalence of HBV and associated factors for MSM and TGW living with or without HIV in Nigeria. Methods Since March 2013, TRUST/RV368 has recruited MSM and TGW in Abuja and Lagos, Nigeria using respondent driven sampling. Participants with HIV diagnosis, enrollment as of June 2015, and available plasma were selected for a cross-sectional study and retrospectively tested for hepatitis B surface antigen and HBV DNA. Logistic regression models were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for factors associated with prevalent HBV infection. Results A total of 717 MSM and TGW had a median age of 25 years (interquartile range [IQR]: 21–27), 5% self-reported HBV vaccination, 61% were living with HIV, 10% had prevalent HBV infection and 6% were HIV-HBV co-infected. HIV mono-infected as compared to HIV-HBV co-infected had a higher median CD4 T cell count [425 (IQR: 284–541) vs. 345 (IQR: 164–363) cells/mm3, p = 0.03] and a lower median HIV RNA viral load [4.2 (IQR: 2.3–4.9) vs. 4.7 (IQR: 3.9–5.4) log10copies/mL, p < 0.01]. The only factor independently associated with HBV was self-report of condomless sex at last anal intercourse (OR: 2.2, 95% CI: 1.3, 3.6). HIV infection was not independently associated with HBV (OR: 1.0, 95% CI: 0.7–1.6). Conclusion HBV prevalence was moderately high but did not differ by HIV in this cohort of MSM and TGW. Recent condomless sex was associated with elevated HBV risk, reinforcing the need to increase communication and education on condom use among key populations in Nigeria. Evaluating use of concurrent HIV antiretroviral therapy with anti-HBV activity may confirm the attenuated HBV prevalence for those living with HIV.

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.

Objective Hepatitis B virus (HBV) can reactivate among rheumatology patients initiating tocilizumab or tofacitinib. HBV screening is recommended by the Centers for Disease Control and Prevention (CDC), the American Association for the Study of Liver Diseases (AASLD), and the Canadian Rheumatology Association but is not explicitly recommended by the American College of Rheumatology. Methods We conducted a cross-sectional study to characterize HBV screening practices for adult rheumatology patients initiating tocilizumab or tofacitinib before December 31, 2018, in the Greater Boston area. We classified appropriate HBV screening patterns prior to tocilizumab or tofacitinib (i.e., HBV surface antigen [HBsAg], total core antibody [anti- HBcAb], and surface antibody [HBsAb]) as: complete (all 3 tested), partial (any 1 or 2 tests), or none. We determined the frequency of inappropriate HBV testing (HBeAg, anti-HBcAb IgM, or HBV DNA without a positive HBsAg or total anti-HBcAb) and used multivariable regression to assess factors associated with complete HBV screening. Results Among 678 subjects initiating tocilizumab, 194 (29%) completed appropriate HBV screening, 307 (45%) had partial screening, and 177 (26%) had none. Among 391 subjects initiating tofacitinib, 94 (24%) completed appropriate HBV screening, 195 (50%) had partial screening, and 102 (26%) had none. Inappropriate testing was performed in 22% of subjects. Race was associated with complete HBV screening (white versus non-white, OR 0.74; 95%CI: 0.57-0.95) while prior immunosuppression was not (csDMARDs, OR 1.05, 95%CI: 0.72-1.55; bDMARDs, OR 0.73, 95%CI: 0.48- 1.12). Conclusion Patients initiating tocilizumab or tofacitinib are infrequently screened for HBV despite recommendations from AASLD and CDC.
