Background: Human immunodeficiency virus infection remains a global pandemic. Co infection with hepatitis B virus leads to rapid progression to AIDS if not diagnosed and promptly treated or better still prevented. The study aims at determining the prevalence and risk factors of hepatitis B infection in HIV infected children being followed up at the Paediatric HIV clinic. Patients and methods: A cross-sectional study of 261 HIV infected children aged eight months to fourteen years to determine the prevalence of Hepatitis B infection and pattern of hepatitis B vaccination was carried out between July and October 2012 at the Paediatric HIV clinic of National Hospital Abuja. Ethical approval was obtained from Ethical Committee of the hospital. Vaccination and transfusion history were obtained from the parents and guardians of the subjects using a proforma after signed informed consent. Blood samples were collected for Hepatitis B surface antigen screening and Hepatitis B screening in those with HBsAg positive blood samples. Results: Only 3 (1.15%) of the 261 HIV infected children had Hepatitis B infection. All the children less than 5 years old in this cohort received hepatitis B vaccination and none of them had Hepatitis B infection. The HIV/HBV co infected children were older than ten years (p = 0.047) and history of blood transfusion (p = 0.003) was also significant. However, scarification (p = 0.996), local circumcision (p = 0.928); uvulectomy (p = 0.898) were not significant risk factors in this cohort. Conclusion: There is need to intensify routine hepatitis B vaccination and routine screening of blood before necessary transfusion. This would further lead to a low prevalence of Hepatitis B in HIV infected children and the general populace at large.

In Denmark, universal screening of pregnant women for hepatitis B has been in place since November 2005, with the first two years as a trial period with enhanced surveillance. It is unknown what the change to universal screening without enhanced surveillance has meant for vaccination coverage among children born to hepatitis B surface antigen (HBsAg)-positive mothers and what risk factors exist for incomplete vaccination. This retrospective cohort study included 699 children of mothers positive for HBsAg. Information on vaccination and risk factors was collected from central registers. In total, 93% (651/699) of the children were vaccinated within 48 hours of birth, with considerable variation between birthplaces. Only 64% (306/475) of the children had received all four vaccinations through their general practitioner (GP) at the age of two years, and 10% (47/475) of the children had received no hepatitis B vaccinations at all. Enhanced surveillance was correlated positively with coverage of birth vaccination but not with coverage at the GP. No or few prenatal examinations were a risk factor for incomplete vaccination at the GP. Maternity wards and GPs are encouraged to revise their vaccination procedures and routines for pregnant women, mothers with chronic HBV infection and their children.

ObjectivesThis study describes the burden of the hepatitis B, C and HIV co-infections and assesses associated risk factors.SettingThis analysis used data from a viral hepatitis screening campaign conducted in six districts in Rwanda from April to May 2019. Ten health centres per district were selected according to population size and distance.ParticipantsThe campaign collected information from 156 499 participants (51 496 males and 104 953 females) on sociodemographic, clinical and behavioural characteristics. People who were not Rwandan by nationality or under 15 years old were excluded.Primary and secondary outcomesThe outcomes of interest included chronic hepatitis C virus (HCV) infection, chronic hepatitis B virus (HBV) infection, HIV infection, co-infection HIV/HBV, co-infection HIV/HCV, co-infection HBV/HCV and co-infection HCV/HBV/HIV. Multivariable logistic regressions were used to assess factors associated with HBV, HCV and HIV, mono and co-infections.ResultsOf 156 499 individuals screened, 3465 (2.2%) were hepatitis B surface antigen positive and 83% (2872/3465) of them had detectable HBV desoxy-nucleic acid (HBV DNA). A total of 4382 (2.8%) individuals were positive for antibody-HCV (anti-HCV) and 3163 (72.2%) had detectable HCV ribo-nucleic acid (RNA). Overall, 36 (0.02%) had HBV/HCV co-infection, 153 (0.1%) HBV/HIV co-infection, 238 (0.15%) HCV/HIV co-infection and 3 (0.002%) had triple infection. Scarification or receiving an operation from traditional healer was associated with all infections. Healthcare risk factors—history of surgery or transfusion—were associated with higher likelihood of HIV infection with OR 1.42 (95% CI 1.21 to 1.66) and OR 1.48 (1.29 to 1.70), respectively, while history of physical traumatic assault was associated with a higher likelihood of HIV and HBV/HIV co-infections with OR 1.69 (95% CI 1.51 to 1.88) and OR 1.82 (1.08 to 3.05), respectively.ConclusionsOverall, mono-infections were common and there were differences in significant risk factors associated with various infections. These findings highlight the magnitude of co-infections and differences in underlying risk factors that are important for designing prevention and care programmes.

SUMMARYWe examined the impact of the neonatal hepatitis B immunization programme, first provided to all neonates born to mothers screened positive for hepatitis B surface antigen (HBsAg) in late 1983, on the age-specific prevalence of HBsAg carriage in teenage mothers managed in 1998–2008. HBsAg carriage was found in 2·5%, 2·7%, 8·8% and 8·0% of mothers aged ⩽16, 17, 18, and 19 years, respectively (P = 0·004), which was also correlated with advancing age (P = 0·011). While neither difference nor correlation with age was found in mothers born before 1984, the prevalence of 1·2%, 1·5%, 7·1% and 8·3%, respectively, was significantly different among (P = 0·008) and correlated with (P = 0·002) age in mothers born 1984 onwards. Regression analysis indicated there was a significantly higher incidence of HBsAg carriage from age 17 onwards (adjusted odds ratio 2·55, 95% confidence interval 1·07–6·10,P = 0·035), suggesting that the protective effect of the vaccine declined in late adolescence.

We aimed to evaluate exposure to hepatitis B and C viruses [HBV and HBC] and candidate risk factors among the Lebanese population. All individuals presenting to all laboratory units in the country over a 2-week period were asked for a 5-mL whole blood sample and answered a questionnaire addressing risk factors. For individuals under 15 years of age the mother was interviewed. In all, 2893 blood samples were examined. Refusal rate was 2.9%. Exposure to HBV antigen was 18.9%; 1.9% were carriers and acute hepatitis B point prevalence was 0.1%. Exposure to HCV antigen was 0.7%. Exposure to both HBc and HCV antibodies was 0.2%. HBc prevalence increased with age and was higher among men. Significant risk factors included blood transfusion, haemodialysis and gastrointestinal endoscopy.

Background and objectives: The World Health Organization has set a target of 90% reduction in new Hepatitis B infections by 2030. The program includes prevention of new infections, and increases testing uptake and treatment. In order to effectively foster prevention, it is necessary to understand the risk factors for transmission. This study aims to determine the risk factors of Hepatitis B infection in pregnant women.Method: A case control study was carried out among 52 pregnant women with HBsAg (+) as cases and 104 pregnant women with HBsAg (-) as controls. The source of cases and controls was the register of pregnant women at the Pringgasela Public Health Center from January 2016 to October 2017. Cases were selected using systematic random sampling from 67 HBsAg (+) pregnant women and controls were selected in the same way from 1644 pregnant women with HBsAg (-). Cases and controls were matched by domicile. The data collected were age, age of first marriage, education, family income, parity, history of miscarriage, maternal or husband’s history of working abroad, frequency of marriage, history of injection, surgery, blood transfusion and dental care. Data collection was carried out with a pre-tested questionnaire in April-May 2018 through interviews at the home of each respondent. Multivariate analysis with logistic regression was carried out to determine the adjusted odds ratio of each risk factor.Results: Case and control characteristics were found to be similar in terms of age, domicile, education and income. Significant risk factors were the history of husband working abroad (AOR=4,115; 95%CI: 1,657-11,075), age of first marriage <20 years (AOR=2,420; 95%CI: 1,157-5,481) and frequency of husband's marriage more than one time (AOR=3,081; 95%CI: 1,345-7,080).Conclusion: Husbands with history of working abroad, age of first marriage <20 years and frequency of husband's marriage more than one time were found to be the risk factors for Hepatitis B infection in pregnant women. These factors require public health attention in order to reduce the transmission of Hepatitis B.

Abstract Abstract 4751 Background The etiology of asymptomatic neutropenia is unknown. We have conducted a community-based study to determine predisposing factors for asymptomatic neutropenia in the Thai population. Method Blood specimens and self-report questionnaires (filled out with assistance from medical personnel) were collected from individuals in Bangkok and 4 surrounding provinces. Asymptomatic neutropenia was defined by an absolute neutrophil count of less than 1.5 × 109/liter, in the absence of any symptoms or known risk factors. Patients with a history of malignancy were excluded. Subjects that met this criterion for neutropenia were examined for the presence of anti-HIV and anti-hepatitis C virus (HCV) antibodies, hepatitis B surface antigen (HBsAg), antinuclear antibody (ANA), rheumatoid factor (RF), thyroid dysfunction, reduced serum ferritin, and reduced serum vitamin B12 and folate; this panel of laboratory tests was also done on control subjects (4 controls for every 1 neutropenic case – see below), which were picked at random from the normal population and were matched for age, sex, site of survey, and underlying disease. Odd ratios (OR) were then computed for significant risk factors. Results Overall, 7,180 individuals were included; 28 had neutropenia (0.39%, 95% CI 0.25–0.53). Based on answers to the questionnaire, the only factor correlating with neutropenia was low body weight (body mass index < 18.5 kg/m2, p = 0.015); age, sex, site and period of survey, underlying disease, medications, herbal ingestion, food supplement, radiation exposure, family history of hematologic disease, alcohol consumption, history of drug abuse or exposure to chemical substance had no significant association with neutropenia. Additional tests on 25 of the neutropenic cases revealed positive findings for HBsAg (20%), anti-HCV antibody (12%), ANA (16%), RF (4%), hypothyroidism (4%), hyperthyroidism (14%) and hypoferritinemia (24%); none showed anti-HIV positivity, or low levels of serum vitamin B12 and folate. Of the 100 normal controls, 4% showed seropositive for HBsAg. HBsAg positivity was thus the significant risk factor associated with neutropenia (OR 6.0, 95%CI 1.48–24.34, p = 0.012). Conclusion HBsAg seropositivity is strongly associated with asymptomatic neutropenia in the Thai population. Low body weight is also correlated with the disorder, perhaps as a result of subtle nutritional deficiencies. Possible mechanisms that underlie neutropenia are currently being explored. Disclosures: No relevant conflicts of interest to declare.

Abstract Background Although overall infection rates of Hepatitis B virus (HBV) in the United States (US) remain stable, as many as 2.2 million persons are still chronically infected with Hepatitis B Virus (HBV)1. Persons who inject drugs (PWID) are at a higher risk of HBV infection and since 2009 three states (KY, TN, WV) have reported up to a 114% increase in cases of acute HBV infection due to higher infection rates among a non-Hispanic white populations (30–39 years), and injection drug users2. Hepatitis B vaccination is recommended as primary prevention for adults who are at increased risk for HBV infection, including PWID. However, data from the National Health Interview Survey indicate that hepatitis B vaccination coverage is low among adults in the general population3, and it is likely to be lower among injection drug users. Hepatitis B Surface Antigen (HBsAg) is the first serological marker to appear after HBV exposure and infection; this marker is included in the recommended panel for acute hepatitis diagnosis and accurate detection is necessary for early and accurate diagnosis. Serological testing challenges exist for HBsAg due to the high degree of genetic variability which can further be exacerbated by endogenous and exogenous pressures. The immuno-dominant region may have one or more mutations described as immune escape mutations which can decrease or abrogate HBsAg binding to antibodies used in immunoassays. Although the prevalence of these mutations is not well documented in the United States, international studies have shown that up to 79% of HBV-reactivated patients (vs 3.1% of control patients; p&lt; 0.001) carry HBsAg mutations localized in immune-active HBsAg regions4. Methods A study was conducted using a panel of 10 unique recombinant HBsAg immune escape mutants. Panel members were tested by commercially available HBsAg serological immunoassays. Results It was found that although commercially available HBsAg immunoassays are the primary diagnostic tool for HBV diagnosis, not all HBsAg immune escape mutants are detected, with some method detecting as few as 5 out of 10 of these mutant samples. Figure 1 Conclusion Improvement is needed in commercially available methods for the accurate detection of HBsAg.

Abstract Hepatitis B is a life-threatening viral liver infection caused by the hepatitis B virus. Neopterin is regarded as an immunologic biomarker of several diseases related to activation of the cellular immune system. Hepatitis B infection is associated with increased production of cellular immune system markers. We aimed to investigate whether there is a relationship between hepatitis B surface antigen-positivity (HBsAg +) and neopterin to determine the role of neopterin in the early diagnosis of hepatitis B infections. Seventy-two HBsAg (+) patients with normal liver function tests and forty-three controls were included in the study. Neopterin levels were 17.6 ± 0.13 nmol/L in HBsAg (+) patients; and 9.12 ± 0.09 nmol/L in infection-free controls, respectively. Compared to the control group, a statistically significant increase (p < 0.001) in the serum neopterin levels of the patients was observed. No significant relationship was determined between neopterin levels and age/sex (both, p > 0.05). With overstimulation of interferon-gamma, the production of neopterin increases by monocytes/macrophages. Likewise with other diseases associated with an activated cellular immune system, this study shows that neopterin can be a predictive biomarker for persistent carriers of hepatitis B infection.
