The DHEC Perinatal Hepatitis B Case Management Program is a component of the DHEC Immunization Program. Nurses in each DHEC Region provide Case Management to infected mothers and their infants. The primary goal of the program is to prevent transmission of the hepatitis B virus by identifying all pregnant women infected with hepatitis B and by ensuring infants born to infected women receive the recommended prophylactic treatment. Prevention of perinatal hepatitis B transmission requires the coordinated transfer of information between laboratories, prenatal care providers, hospitals, primary care providers, and state/local health departments. CDC components of case management programs to prevent hepatitis B virus infection include the following: ...

For additional information on hepatitis B virus (HBV) and HIV, see HIV/Hepatitis B (HBV) Coinfection in the Adult and Adolescent Guidelines1 and Hepatitis B Virus Infection in the Adult and Adolescent OI Guidelines.2 The management of HIV/HBV coinfection in pregnancy is complex and consultation with an expert in HIV and HBV infection is strongly recommended.. Screening and Vaccination All women living with HIV should be screened for HBV and hepatitis C virus (HCV) at entry into general HIV care. All pregnant women living with HIV should be screened during each pregnancy for HBV unless they are known to have HIV/HBV coinfection and for HCV unless they are known to have HIV/HCV coinfection. Screening for HBV should include hepatitis B surface antigen [HBsAg], hepatitis B core antibody [anti-HBc], and hepatitis B surface antibody [anti-HBs]. Women who test positive for HBsAg should have follow-up testing that includes liver function tests, prothrombin time, HB e antigen, HB e antibody, and HBV DNA ...

The purpose of this study is to identify the effect of prophylactic entecavir in HBsAg Negative/HBcAb Positive/hepatitis B virus DNA Negative patients with lymphoma are randomized into entecavir prophylaxis group or observation group. In entecavir prophylaxis group, entecavir 0.5 mg/day orally is initiate on day 1 of the first course of antitumor therapy, and will be continued until at least 6 months after completion of antitumor therapy. In observation group, entecavir 0.5mg daily will be prescribed for patients with hepatitis B virus reactivation ...

Occult Hepatitis B infection is characterized by the presence of HBV DNA without detectable HBsAg, with or without the presence of HBV antibodies outside the acute phase window period [8]. A number of possible mechanisms have been suggested for the pathogenesis of occult Hepatitis B infection, although it is most likely multifactorial, depending upon both host and viral factors. The majority of cases are secondary to overt HBV infection and represent a residual low level viraemia suppressed by a robust immune response, together with abnormal histological findings on liver biopsy which developed either during the acute or chronic phase of HBV infection [9,10].. In our study, a sensitive real time quantitative PCR assay was used to determine the presence of occult Hepatitis B infection in a large cohort of inner city adult patients receiving maintenance haemodialysis. We did find occult HBV, although the prevalence and levels of detectable circulating HBV were low.. Some studies have observed a ...

Each year, an estimated 20,000 infants are born to women in the United States who are positive for hepatitis B surface antigen (HBsAg). These infants are at high risk for perinatal hepatitis B virus (HBV) infection and for chronic liver disease as adults. To identify newborns who require immunoprophylaxis to prevent perinatal HBV infection (1-4), all vaccine advisory groups have recommended routine HBsAg screening of all pregnant women during an early prenatal visit in each pregnancy. Federal funding to support perinatal hepatitis B-prevention programs became available in 1990, and by 1992, programs had been implemented in all 50 states and the District of Columbia. Specific objectives of these programs are to ensure that 1) all pregnant women are tested for HBsAg, and 2) infants born to HBsAg-positive women receive hepatitis B immune globulin (HBIG) and hepatitis B vaccine at birth, with follow-up doses of vaccine at ages 1 and 6 months (5). This report describes the case-management features of ...

Sharing of blood glucose monitoring equipment in assisted-living facilities has resulted in at least 16 outbreaks of hepatitis B virus (HBV) infection in the United States since 2004 (1,2). On October 12, 2010, the North Carolina Division of Public Health (NCDPH) and the Wayne County Health Department were notified by a local hospital of four residents of a single assisted-living facility with suspected acute HBV infection. NCDPH requested HBV testing of all persons who had resided in the facility during January 1--October 13, 2010, and defined an outbreak-associated case as either 1) positive hepatitis B surface antigen and core immunoglobulin M (IgM) results or 2) clinical evidence of acute hepatitis (jaundice or serum aminotransferase levels twice the upper limit of normal) with onset ≥6 weeks after admission to the facility. Records were reviewed for potential health-care--associated exposures and HBV-related risk factors. Infection control practices were assessed through observations and ...

Among adults, hepatitis B transmission occurs primarily among unvaccinated adults with risk behaviors for hepatitis B transmission, including having multiple sex partners and sex partners of people with chronic hepatitis B infection. Hepatitis B is easily transmitted through sexual activity. Sexual contact is the most common way hepatitis B is spread in the United States.. Among adults seeking treatment in STD clinics, as many as 10%-40% have evidence of past or current hepatitis B virus infection. Many of these infections could have been prevented through universal vaccination during delivery of STD prevention or treatment services. A study of adults diagnosed with acute hepatitis B found that 39% had sought care or been screened for an STD before they were infected with hepatitis B, indicating a significant missed opportunity to vaccinate at-risk persons when they first access STD prevention or treatment services.. Offering vaccination to all adults as part of routine prevention services in ...

Hepatitis B is a serious liver infection caused by Hepatitis B virus. Chronic Hepatitis B infection leads to increased risk for liver cirrhosis, liver cancer and consequent death due to these conditions. The major modes of transmission include mother to child during birth, blood exposure and during sexual contact. The Hepatitis B infection can be prevented through three doses of Hepatitis B vaccination given over a period of six months and the control of Hepatitis B infections includes costly antiviral medications. As per World Health Organization (WHO), the regions of the world with hepatitis B prevalence rate less than 2% have low endemicity, those having prevalence rate of 2-7% are of medium endemicity and regions with prevalence rate greater than 7% are categorized as highly endemic. India falls in medium endemic region with Hepatitis B prevalence rate ranging from 2-7%..

May is Hepatitis Awareness Month and Saturday, May 19this National Hepatitis Testing Day in the United States. This day is an opportunity to increase awareness and testing for both hepatitis B and C. It is also a reminder for health care providers and the public of the importance of testing for viral hepatitis.. Why is hepatitis B testing necessary? Hepatitis B is largely asymptomatic, which means that symptoms dont always occur or are not obvious. Some people will not know that they have hepatitis B until it is too late, or they may learn of their infection from a blood donation screening or lab work. There are groups of people who have a greater risk of hepatitis B compared to others, so it doesnt hurt to be sure. here are some places around the world that have an extremely high hepatitis B prevalence (where many people are infected). It is important that people who are at high risk for a hepatitis B infection see a doctor to get tested, to find out if they have a hepatitis B infection. ...

Hepatitis B The disease known as Hepatitis B is caused by the infectuous Hepatitis B virus (HBV). HBV alone has infected about 400 million people in the world, which makes HBV one of the most common pathogens. Almost 700 million U.S. Dollars are spent every year for treating Hepatitis patients. Structure: HBV is a 42 nm doubleshelled deoxyribonucleic acid (DNA) virus of the class Hepadnaviridae. The outer surface membrane contains Hepatitis B surface antigen (HBsAg), which also circulates in blood as 22 nm spherical and tubular particles. The inner core of the virus contains Hepatitis B core antigen (HBcAG), Hepatitis B e antigen (HBeAg), a single molecule of partially doublestranded DNA, and DNA dependent DNA polymerase.. How it is transmitted? Hepatitis B is transmitted by sexual contact or by blood. People who are at risk by being infected by HBV are drug users, homosexuals, active heterosexuals, infants born from infected mothers and children of immigrants from disease-endemic areas. ...

Hepatitis B is NOT spread through sneezing, coughing, hugging or breastfeeding. Even though the virus can be found in saliva, you cant get it from kissing or sharing forks, spoons, or knives with someone whos infected.. If you dont have hepatitis B, get vaccinated and ask your partner to get vaccinated, too. Vaccination is the best way to prevent hepatitis B.. Hepatitis B and pregnancy. If you have hepatitis B during pregnancy and its not treated, you can pass it to your baby. This can happen during a vaginal delivery or a c-section. About 9 out of 10 babies (90 percent) infected at birth develop chronic hepatitis B infection. This infection can cause life-long liver problems for your baby.. Getting tested for hepatitis B is a routine part of prenatal care. Your health care provider will test for hepatitis B and other infections at your first prenatal care checkup.. If you do test positive for hepatitis B, your health care provider may prescribe you an antiviral medication during your ...

FIRNHABER, Cynthia et al. The prevalence of hepatitis B co-infection in a South African urban government HIV clinic. SAMJ, S. Afr. med. j. [online]. 2008, vol.98, n.7, pp.541-544. ISSN 2078-5135.. OBJECTIVE: There are an estimated 350 million hepatitis B carriers worldwide. In South Africa the prevalence of monoinfection with hepatitis B has been estimated to range from 1% in urban areas to approximately 10% in rural areas. The exact prevalence of hepatitis B in the HIV-infected population has not been well established. Hepatitis B screening is not standard practice in government HIV clinics. Co-infection with hepatitis B and HIV can influence antiretroviral treatment and prognosis of both diseases. The purpose of this study was to evaluate the prevalence of hepatitis B/HIV coinfection. DESIGN: This is believed to be the first prospective observational report on the prevalence of hepatitis B/HIV co-infection in South Africa. Patients on whom hepatitis B serological tests could not have been done ...

Hepatitis B vaccine and Hepatitis B immunoglobulin seem safe, but few trials reported adverse events.. Dr Gongs team commented, Hepatitis B vaccine, Hepatitis B immunoglobulin, and vaccine plus immunoglobulin prevent Hepatitis B occurrence in newborn infants of mothers ...

Co-infections of hepatitis B and C viruses are frequent with HIV due to shared routes of transmission. In most of the tertiary care health settings, HIV reactive patients are routinely tested for HBsAg and anti-HCV antibodies to rule out these co-infections. However, using the routine serological markers one can only detect active HBV infection while the occult HBV infection may be missed. There is insufficient data from India on HIV-HBV co-infection and even scarce on occult HBV infection in this group. We estimated the burden of HBV infection in patients who were tested positive for HIV at a tertiary care centre in north India. We also attempted to determine the prevalence and clinical characteristics of occult HBV infection among these treatment-naïve patients and compare their demographic features with other HIV patients. During a period of 6 years between January 2002 to December 2007, 837 HIV positive patients (631 males and 206 females (M: F :: 3.06:1) were tested for serological markers of HBV

Abstract Current estimates put the prevalence of hepatitis B virus (HBV) infection in Kenya at 5-8%. We determined the HBV infection prevalence in the human immunodeficiency virus (HIV)-negative Kenyan adult and adolescent population based on samples collected from a national survey. We analyzed data from HIV-negative participants in the 2007 Kenya AIDS Indicator Survey to estimate the HBV infection prevalence. We defined past or present HBV infection as presence of total hepatitis B core antibody (HBcAb), and chronic HBV infection (CHBI) as presence of both total HBcAb and hepatitis B surface antigen (HBsAg). We calculated crude and adjusted odds of HBV infection by demographic characteristics and risk factors using logistic regression analyses. Of 1,091 participants aged 15-64 years, approximately 31.5% (95% confidence interval [CI] = 28.0-35.3%) had exposure to HBV, corresponding to approximately 6.1 million (CI = 5.4-6.8 million) with past or present HBV infection. The estimated prevalence of CHBI

BACKGROUND:. A baseline study on the vertical transmission of hepatitis B virus in Taiwan revealed that 15 percent of all pregnant women were persistent carriers of hepatitis B antigen and that 40 percent of their new babies developed a protracted antigenemia during the first 6 months of life. The incidence of acute hepatitis, cirrhosis, and hepatoma was high in Taiwan, and patients with these disorders had a fivefold to sixfold higher prevalence of hepatitis B antigen than healthy persons. Given the important public health problems of this disease in Taiwan and the rest of the Third World, this trial sought to answer the important question of whether hepatitis B immune globulin with a high level of antibody against the antigen would be of utility in combating the problem.. Two hundred and five babies were accepted into the study, which was actually conducted on Taiwan through a contract to the Community Blood Council of Greater New York. Only those babies born of mothers who had HBsAg ...

One reason some parents dont vaccinate their children against the hepatitis B virus (HBV) is their belief that their child has no risk of ever coming in contact with the virus. My child will never be sexually promiscuous or addicted to drugs! Why does he or she need to be protected against hepatitis B? Of course, it is impossible to predict which children will grow up and engage in risky behavior. But lets assume for a moment that this hypothetical parent is right . . . does this mean that his or her child has no possibility of ever coming in contact with HBV?The truth is that transmission of HBV can sometimes occur in unusual ways. Approximately 30% of people newly infected with HBV do not know how they contracted the virus. The following reports of some uncommon methods of HBV transmission illustrate how every unvaccinated person is at some (albeit limited) risk of HBV infection. 1. Between April 1984 and February 1985, thymectomy. The thoracic surgery physician- found 75 who developed HBV ...

BACKGROUND Infant immunization against hepatitis B began in Uganda in 2002. OBJECTIVE To determine the baseline prevalence of hepatitis B virus (HBV) infection and explore risk factors. METHODS A hepatitis B prevalence study was nested in the 2005 national HIV/AIDS serobehavioural survey. Demographic characteristics and risk factors were explored by questionnaire. One third of blood specimens (n=5875) from adults aged 15 to 59 years were tested for hepatitis B core antibodies (HBcAb); positive specimens were tested for hepatitis B surface antigen (HBsAg). RESULTS HBcAb was present in 52.3% (95% CI: 51.0-53.6) of adults, and HBsAg in 10.3% (9.5-11.1). By 15-19 years of age, 40.0% had been infected with HBV. Prevalence of both markers was significantly higher across northern Uganda, in rural areas, among the poor and least educated, and in uncircumcised men. Other independent predictors of infection were age, ethnic group, occupation, number of sex partners, and HIV and HSV-2 status. CONCLUSION

FROM THE NEW ENGLAND JOURNAL OF MEDICINE. Prenatal tenofovir didnt reduce the rate of hepatitis B among infants born to women infected with the virus.. Among 322 6-month-olds, the rate of HBV transmission was 0 in those whose mothers received the antiviral during pregnancy and 2% among those whose mothers received placebo - not a statistically significant difference, Gonzague Jourdain, MD , and his colleagues reported in the New England Journal of Medicine . All of the infants in the study, who were born in Thailand, got hepatitis B immune globulin and began a 5-dose HBV vaccination schedule within the first few hours after birth, something that may have contributed to the low rate of HBV transmission that was observed in the study, said Dr. Jourdain, a visiting scientist at the Harvard School of Public Health, Boston.. The study randomized 331 pregnant women with proven HBV infections to either tenofovir or placebo from 28 weeks gestation to 2 months post partum. All infants received HBV ...

The inflammation of the liver is called hepatitis. There are many causes of hepatitis and one of them is viral infection. There are five major viruses that are of medical concern: hepatitis A, hepatitis B, hepatitis C, hepatitis D, and hepatitis E. Hepatitis B is a viral hepatitis caused by the Hepatitis B virus (HBV) (i.e. from genus Orthohepadnavirus). It spreads mainly through contact with contaminated blood and blood products. Thus, it is formerly called serum hepatitis. It may also be transmitted by sexual contact or by mother-to-infant route. It is also formerly called long incubation hepatitis based on the longer incubation period (generally 30-180 days, usually 60-90) compared to hepatitis A (15-45 days, mean 30). Hepatitis B can cause a much more severe infection than hepatitis A and can occur as an asymptomatic carrier state, a chronic infection or as cirrhosis of the liver. Those at risk (IV drug abusers, health care workers, dialysis patients, transfusion recipients, homosexuals) ...

An unvaccinated person who may have been exposed to the Hepatitis B virus should contact a health care provider immediately. If a person who has been exposed to Hepatitis B virus receives the Hepatitis B vaccine and/or a shot called HBIG (Hepatitis B immune globulin) within 24 hours, infection may be prevented.. Infants born to mothers infected with hepatitis B should receive HBIG. HBIG gives baby a boost or extra help to fight the virus and works best when given within the first 12 hours of life. The baby will also need to complete the full hepatitis B vaccination series for best protection.. ...

Blood tests can be taken to check for hepatitis B. Blood tests show if a person has had hepatitis B in the past and whether the infection is acute or chronic. Tests can also show if there is any damage to the liver.. There is a reliable and safe vaccine available to prevent the spread of hepatitis B. Routine immunization with hepatitis B vaccine is strongly recommended for the prevention of HBV infection in individuals at risk for STIs. HBV vaccination of adults has been found to be effective at conferring immunity to individuals who are exposed to HBV via sexual transmission. However, the first priority is directly preventing the spread of HBV by the most reliable and appropriate method, which is use of a condom for safe sexual contact.. As people with hepatitis B are carriers for the disease, they:. must not donate blood, semen or organs. should inform their doctor, dentist and other relevant health workers of their hepatitis B status. If anyone find out that he has hepatitis B, he should ...

The discovery at the end of the 1960s that the Australia antigen (now called hepatitis B surface antigen [HBsAg]) is a component of hepatitis B virus (HBV) opened the door to preparation of hepatitis B immune globulin (HBIG) having titers of specific antibody (anti-HBs) many hundredfold times higher than those in standard immune serum globulin (ISG). As rapidly as anti-HBs-rich units of plasma could be identified and batches of HBIG prepared, studies of prophylaxis of type B hepatitis were carried out (1-6). Unfortunately, these investigations did not provide an easily interpretable answer to relative usefulness of HBIG and ISG. Hence, ...

The role of active hepatitis B virus (HBV) infection in chronic HBsAg positive hepatitis with and without hepatitis delta virus (HDV) superinfection was analysed in percutaneous liver biopsy specimens from 50 patients. Each specimen was divided into two--one part for histological evaluation and for the detection of HBcAg and delta antigen; the other part was tested for HBV-DNA using Southern blotting. Ten cases were of chronic lobular hepatitis, 10 of chronic persistent hepatitis, and 30 of chronic active hepatitis. Ten cases were delta antigen positive and showed high grade lobular activity but no evidence of HBV-DNA episomal forms or HBcAg reactivity. Twenty one cases showed HBV-DNA replicative intermediate forms; 19 had high grade lobular activity, which occurred in five cases without evidence of free viral DNA. Of the 21 biopsy specimens with HBV-DNA episomal forms, 14 were positive for HBcAg; only one of the 19 cases without detectable viral DNA was positive for such antigen. These data ...

Hepatitis refers to a disease that may result in inflammation of the liver. The most common types of hepatitis are hepatitis B and hepatitis C.. Hepatitis B (hep B) is an infection of the liver caused by a virus. The virus attaches to healthy liver cells and multiplies there which triggers the bodys immune system. It is estimated that 225, 000 Australians are chronically infected with hep B. Those with the greatest risk of having hepatitis B include migrants from areas where hepatitis B is widespread including Asia, Africa, Russia and Eastern Europe, as well as Indigenous Australians, people who participate in high risk sexual activity and people who inject drugs. Hepatitis B infection can lead to cirrhosis (scarring of the liver), liver cancer or liver failure if it is not diagnosed and managed. People are often unaware they have been infected with hepatitis B as there are not rarely any symptoms in its early stages.. Hepatitis C (hep C) is also an infection of the liver caused by a virus, ...

Abstract This study examined factors affecting the receipt of both hepatitis B vaccination and screening in the Vietnamese American community of Philadelphia. Hepatitis B is endemic in Southeast Asia; individuals emigrating from endemic areas are at a particularly high risk of hepatitis B infection, resulting in a higher prevalence of liver cancer in the population. Participants recruited at Vietnamese community events in Philadelphia completed a self-administered written questionnaire. In a sample of 207 participants (93% foreign-born), over one half reported that they had not received either a screening or vaccination for hepatitis B in their lifetime. The number one predictor of receiving either service was that the participant was aware of the cancer risk posed by hepatitis B. This association remained strong even when controlling for socio-demographic factors. Based on this finding, future interventions targeting this population should include messages on the cancer risk associated with ...

In 2015, 19 cases of acute hepatitis B virus (HBV) infection (0.3 per 100,000 population) were reported. In 2012, the case definition for acute hepatitis B was revised to include laboratory confirmed asymptomatic acute cases. Three of the 19 cases of acute hepatitis B were asymptomatic, laboratory-confirmed infections.. Acute cases ranged in age from 22 to 65 years (median, 42 years). Fifteen (79%) cases were residents of the metropolitan area, including 9 (47%) in Hennepin County and 3 (16%) in Ramsey County. Fifteen (79%) cases were male and 8 (42%) were adolescents or young adults between 13 - 39 years of age. Race was known for 14 cases; of those, 9 were white, 2 were black, 2 were multi-racial, and 1 was Asian. Hispanic ethnicity was reported for 1 case. Incidence rates were higher among Asians (0.4 per 100,000) and blacks (0.6 per 100,000), than among non-Hispanic whites (0.2 per 100,000).. One hundred sixty-five reports of newly identified cases of confirmed chronic HBV infection were ...

Table 1. Rate of perinatal hepatitis B transmission based on maternal viral load at delivery, in infants receiving post-natal prophylaxis (3).. In view of this it is recommended that anti-viral therapy be considered in pregnant females with high viral loads (HBV DNA levels , Log 5.3)(4-6). The optimal antiviral treatment in this situation is less clear. In 2016 the American Association for the Study of Liver Disease (AASLD) published a meta-analysis of antiviral therapy to prevent transmission in highly viraemic women(7). Twenty six studies enrolled 3,622 pregnant females. Ten were randomized controlled trials, including a total of 780 participants. The drugs used were lamivudine, telbuvidine and tenofovir. All drugs lowered maternal HBV DNA levels and appeared to reduce rates of maternal to child transmission. However it was noted that most trials were small and there was limited safety data.. In the meantime two relatively large randomized trials using tenofovir to prevent maternal to child ...

Have you recently been told you have hepatitis B? Dealing with the diagnosis and waiting out the next six months to determine if your infection will resolve itself or learning that it is a chronic infection can be nerve-wracking.. Fortunately, greater than 90 percent of healthy adults who are newly infected will clear or resolve an acute hepatitis B infection. On the hand, greater than 90% of babies and up to 50% of children infected with hepatitis B will have lifelong, chronic infection. Sometimes people are surprised to learn they have a chronic infection. It can be confusing since there are typically few or no symptoms for decades. If a person continues to test hepatitis B positive for longer than 6 months, then it is considered a chronic infection. Repeat testing is the only way to know for sure.. Acute hepatitis B patients rarely require hospitalization, or even medication. If you are symptomatic, (some symptoms include jaundice, dark urine, abdominal pain, fever, general malaise) you may ...

Clinical trials of drugs for treatment of chronic hepatitis B viral infections may use multiple efficacy endpoints, the FDA said in new draft guidance released Nov. 1. The endpoints can include the suppression of hepatitis B virus (HBV) DNA on-treatment, the agency said. Other endpoints could include suppression of HBV DNA for more than six months off-treatment after an initial therapy period and sustained suppression off-treatment with loss of HBV surface antigens. Liver disease progression is an important endpoint, but assessing it can be challenging . . .

Family physicians encounter diagnostic and treatment issues when caring for pregnant women with hepatitis B or C and their newborns. When hepatitis B virus is perinatally acquired, an infant has approximately a 90 percent chance of becoming a chronic carrier and, when chronically infected, has a 15 to 25 percent risk of dying in adulthood from cirrhosis or liver cancer. However, early identification and prophylaxis is 85 to 95 percent effective in reducing the acquisition of perinatal infection. Communication among members of the health care team is important to ensure proper preventive techniques are implemented, and standing hospital orders for hepatitis B testing and prophylaxis can reduce missed opportunities for prevention. All pregnant women should be screened for hepatitis B as part of their routine prenatal evaluation; those with ongoing risk factors should be evaluated again when in labor. Infants of mothers who are positive for hepatitis B surface antigen should receive hepatitis B immune

Thanks for sending Chuan Qians records for review. Hes a lovely little boy who appears to be doing reasonably well.. His growth is marginal for his given age. however, since they estimated his birthday and we dont know his birthweight or gestational age, his growth could be completely appropriate for his actual age. His update in November puts him slightly below or at the lower limits of normal. Im reasonably certain that hell catch up nicely when he reaches your home and grow within the normal range. His lab tests showed a weakly positive hepatitis B surface antibody which may be due to his immunizations. He also had a weakly positive hepatitis B e antibody which could either be a false positive or be antibody transferred from his birth mother prior to birth. The most important test was the hepatitis B surface antigen which was negative so he doesnt have hepatitis B. He also tested negative for HIV and syphilis. His development is close to being normal for his given age. Again, it may be ...

Viral hepatitis is liver inflammation due to a viral infection. It may present in acute (recent infection, relatively rapid onset) or chronic forms. The most common causes of viral hepatitis are the five unrelated hepatotropic viruses hepatitis A, hepatitis B, hepatitis C, hepatitis D, and hepatitis E. In addition to the nominal hepatitis viruses, other viruses that can also cause liver inflammation include cytomegalovirus, Epstein-Barr virus, and yellow fever. Up to 1997 there has been also 52 cases of viral hepatitis caused by herpes simplex virus. There is the opportunity to prevent or treat the most common types. Hepatitis A and hepatitis B can be prevented by vaccination. Effective treatments for hepatitis C are available but expensive. In 2013 about 1.5 million people died from viral hepatitis. Most deaths are due to hepatitis B and hepatitis C. East Asia is the region of the world most affected. Play media The most common cause of hepatitis is viral. Although they are classified under the ...

Hepatitis B Surface Antigen Negative, Hepatitis B Surface Antibody Negative. Recommendation: Get immunized with the hepatitis B vaccine.. Hepatitis B Surface Antigen Negative, Hepatitis B Surface Antibody Positive. Person has antibodies to hepatitis B and is immune. Encourage him/her to have family tested.. CLIENT FOLLOW UP PROTOCOL:. You will need some sort of follow up system. Simply sending persons a letter notifying them that they are hepatitis B positive is not effective. This is one of the best areas for students to get involved because you can help develop tracking programs and follow-up with both your hepatitis B surface antigen positive and negative persons. Hepatitis B surface antigen positive persons need to see a physician even if they have no symptoms. It is ideal to follow up with everyone who participates in your screening to educate them about hepatitis B and also direct them to appropriate avenues for treatment.. Hepatitis B negative persons who also are hepatitis B surface ...

Although hepatitis B vaccinations have been integrated in the Universal Immunization Program (UIP) in India over a decade, only half of the children are immunized against hepatitis B. The national average in hepatitis B vaccination conceals large variations across states, districts and socio-economic groups. In this context, the aim of this paper is to examine the spatial heterogeneity and contextual determinants of hepatitis B vaccination across the districts of India. Using data of 199,899 children aged 12-59 months from the National Family Health Survey-4 (NFHS-4), 2015-16 we have examined the district level spatial distribution and clustering of hepatitis B vaccination with the help of Morans I and Local Indicator of Spatial Autocorrelation (LISA) measures. We investigated the low coverage of HBV vaccination using spatial autoregressive models (SAR) at the meso scale. And we applied multivariate binary logistic regression analysis to understand the micro-level predictors of hepatitis B vaccination.

Since its widespread introduction, the hepatitis B vaccine has become an essential part of infant immunization programmes globally. The vaccine has been particularly important for countries where the incidence of hepatitis B virus-related hepatocellular carcinoma is high. Effective treatment options for individuals with chronic hepatitis B infection were limited until 1998 when lamivudine, the first nucleoside analogue drug, was introduced. As a single treatment agent, however, lamivudine has a significant drawback: it induces lamivudine-resistant hepatitis B virus strains that may pose a risk to the global hepatitis B immunization programme. Mutations associated with drug treatment can cause changes to the surface antigen protein, the precise part of the virus that the hepatitis B vaccine mimics. However, the emergence of antiviral drug-associated potential vaccine escape mutants (ADAP-VEMs) in treated patients does not necessarily pose a significant, imminent threat to the global hepatitis B ...

Hepatitis B is a global public health issue, with some 2 billion people having current or past infection. In Africa, 65 million are chronically infected, an estimated 2.5 million of them in South Africa (SA). Hepatitis B and the associated complications of cirrhosis and hepatocellular carcinoma are entirely vaccine preventable. SA was one of the first ten countries in Africa to introduce universal hepatitis B vaccination in April 1995, but has no birth dose or catch-up programme. Although universal infant vaccination in SA has been successful in increasing population immunity to hepatitis B, improvements in terms of implementing protocols to screen all pregnant mothers for hepatitis B surface antigen (HBsAg) and ensuring full hepatitis B coverage, especially in rural areas, is required. The World Health Organization has recommended a birth dose of hepatitis B vaccine in addition to the existing hepatitis B vaccine schedule in order to further decrease the risk of perinatal transmission. We recommend

We compared the long-term effectiveness of accelerated (0-1-2 months) and standard (0-1-6 months) hepatitis B vaccination schedules in preventing hepatitis B virus (HBV) infections and anti-hepatitis B (anti-HBs) antibody loss during 2-year follow-up in 707 drug users (HIV and HBV negative at enrollment and completed 3 vaccine doses) from February 2004 to October 2009. Results. Drug users in the accelerated schedule group had significantly lower HBV infection rates, but had a similar rate of anti-HBs antibody loss compared with the standard schedule group over 2 years of follow-up. No chronic HBV infections were observed. Hepatitis C ...

Since its discovery by Blumberg in 1965, the hepatitis B surface antigen (HBsAg) is used as the fingerprint of hepatitis B infection. Occult hepatitis B infection (OBI) is defined by a viral replication (DNA detectable) in the absence of HBsAg. Burkina Faso is a high endemic area where the prevalence is higher than 14%. At the National Center for Blood Transfusion (NCBT) of Ouagadougou, HBsAg is the only sought marker used to distinguish donors towards Hepatitis B Virus (HBV). Acceptation of blood donation is based specifically on the absence of HBsAg, which exposes to the risk of HBV transmission during transfusion. The goal of this study is to evaluate this risk by determining the prevalence of OBI in blood donors. Patients and Methods: It was a five-month prospective study on blood donations collected from January to May 2016. The HBc antibody has been sought in the serums of negative HBsAg donors.

Vaccination Report: Why hepatitis B vaccine for all children?. Nineteen states have passed laws requiring three doses of hepatitis B vaccine for all healthy children. Most 12-hour-old newborns cant leave the newborn nurseries of hospitals without being injected with hepatitis B virus vaccine.. Why?. Not content with using the hepatitis B vaccine in high risk populations such as IV drug users, prostitutes, prisoners and sexually promiscuous adults for which this vaccine was created, drug companies and officials at the Centers for Disease Control (CDC) have targeted vulnerable newborns in the first moments of life to find a larger and more reliable market for their produce.. Using the justification that babies born to mothers infected with hepatitis B disease have an 85-95% risk of developing chronic hepatitis B infection and promoting the idea that injecting all healthy babies with hepatitis B vaccine will protect them when they are teenagers and become sexually active, CDC officials have ...

Hepatitis B, caused by infection with the hepatitis B virus, is a contagious liver disease that ranges in severity from a mild illness lasting a few weeks to a serious, lifelong illness. Acute hepatitis B is a short-term illness that occurs within the first 6 months after someone is exposed to the virus. Acute infection may lead to chronic infection. Chronic hepatitis B virus infection is a long-term illness that occurs when the hepatitis B virus remains in a persons body. This can eventually lead to serious health problems, including liver damage, liver cancer, and even death.. Not all people with acute hepatitis B have symptoms. However, if they appear, symptoms can include fever, fatigue, loss of appetite, nausea, vomiting, abdominal pain, dark urine, clay-colored bowel movements, joint pain, and jaundice (yellow color in the skin or the eyes).. Hepatitis B is spread when blood, semen, or other body fluid infected with the hepatitis B virus enters the body of a person who is not infected. ...

The hepatitis B vaccine protects against infection with the hepatitis B virus. A hepatitis B infection can damage the liver and lead to liver cancer.. The vaccine is given to adults in three or four doses. You receive the shots in your upper arm. After you get all the doses, you will be protected for at least 15 years. This vaccine is safe for women who are pregnant or breastfeeding.. If you are exposed to hepatitis B before you get all the shots, you may need a hepatitis B immunoglobulin (HBIG) shot. This gives you instant protection. The HBIG shot will prevent infection until your hepatitis B vaccine takes effect.. The vaccine may cause pain at the injection site. It can also cause a mild fever for a short time. You should not get the hepatitis B vaccine if you are allergic to bakers yeast. This is the kind of yeast used to make bread. And you should not get the next dose if you had a bad reaction to the first shot.. Ask your doctor about when you need the next shot.. ...

Since 1998 I have been examining and developing a new way of medicamentous therapy for acute and chronic viral hepatitis B and С using Natrii Hypochloriti (NaClO). This medicament received the sanction of Pharmacological committee of the Russian Federation for clinical application. I invented and clinically proved long-term antiviral effectiveness of NaClO therapy for viral hepatitis B and C, which has been provided documentary evidence. I took out the patent of the Russian Federation for this invention. On this theme I defended a thesis and have already published near the 100 scientific articles.. After the completion of the first course of taking NaClO medication 40% of patients with viral hepatitis B and 38% of patients with viral hepatitis C are determined absence of hepatitis (absence of DNA HBV, absence RNA HCV, decrease or neglected levels of viral load, normalization of a specific antibodies, normalization of ALT, AST, bilirubin, lipid peroxidase) in blood test determined by method ...

Summary. There are limited data on the use of lamivudine for patients with severe forms of acute hepatitis B. We report our experience with the use of lamivudine in six patients with acute HBV infection. Lamivudine was justified by disease severity for four patients and by concerns about risk of chronicity for two patients. The diagnoses of the treated patients were: fulminant liver failure (two patients), severe acute hepatitis B, protracted acute hepatitis B, and new HBV infection in the renal dialysis setting (two patients, one with severe liver injury). Serum HBV DNA titres ranged from 105 to 107 copies/mL prior to commencement of lamivudine. Lamivudine treatment was associated with a decline in serum HBV DNA and serum transaminases in all patients. All but one patient survived. A 58-year-old man with fulminant hepatitis and multiple organ failure died despite antiviral treatment. When possible, HBeAg and HBsAg seroconversion was documented during follow-up. In the absence of a randomized, ...

Hepatitis B is a liver disease caused by infection with Hepatitis B Virus (HBV). Infection from HBV can cause acute or chronic liver inflammation that can progress to cirrhosis or liver cancer. Hepatitis B has caused nearly 600 000 people experiencing disability and around 31 000 deaths each year in Southeast Asia. Hepatitis B is spread through the transmission source vertically or horizontally. Vertical transmission occurs from mothers who suffered from Hepatitis B to babies who are born during delivery or shortly after childbirth. Horizontally, can occur due to the use of contaminated syringes, ear piercing, blood transfusion, sharing razors and toothbrushes as well as having sexual relations with people with Hepatitis B. The purpose of this study was to determine the prevalence of Hepatitis B and Hepatitis B risk factors in Hospital Universiti Sains Malaysia. This research was conducted by searching the medical records of patients that includes the number of patients diagnosed with Hepatitis ...

PURPOSE: Hepatitis B vaccine has become an effective means of preventing complications of hepatitis B. However, it occasionally induces serious side effects. We report a case of multiple evanescent white dot syndrome (MEWDS) that occurred following hepatitis B vaccination. METHODS: A 23-year-old woman with a one-week history of progressive loss of vision in the left eye and bilateral photopsia was referred for examination. Her symptoms appeared 24 hours after a booster intramuscular injection of hepatitis B vaccine. RESULTS: Clinical examination, fluorescein angiography, and the course of events were typical of MEWDS. CONCLUSIONS: This case demonstrates the occasional occurrence of MEWDS after hepatitis B vaccine and suggests that hepatitis B virus immunization may be a risk factor for this retinal condition.

The United Kingdom is one of the few developed countries that have not implemented universal immunization. Instead, it follows a policy of selective immunization of high-risk groups, and screening all women attending antenatal clinics. But this approach has come in for some criticism. So, is the British selective program effective and should the UK now adopt universal immunization against hepatitis B, ask the authors?. Although the UK has one of the lowest incidences of hepatitis B infection worldwide, the Health Protection Agency estimated that only 44 percent of infections are potentially preventable under the current program.. Of particular importance is the average net immigration of about 6,500 people with chronic hepatitis B infection each year between 1996 and 2000, say the authors. This total is cumulative, and therefore the pool is increasing. For example, in Ireland, the incidence of hepatitis B infection increased markedly between 1997 and 2003, in part reflecting migration from ...

Abstract: Reactivation of hepatitis B virus infection in subjects receiving cytotoxic treatment for heamatological malignancies occurs in 21-53% of chronic HBsAg carriers and in an unknown number of HBsAg negative subjects harbouring occult HBV infection. Immunotherapy with alemtuzumab, a humanized monoclonal antibody against CD52 epitopes on lymphocytes cells produces deep immunosuppression. We describe two subjects with chronic lymphocytic leukaemia and occult HBV infection who developed a virological and biochemical flare of hepatitis B following immunotherapy with alemtuzumab. One of them developed full blown hepatitis with seroreversion from anti-HBs to HBsAg after four weeks of alemtuzumab therapy. Lamivudine (100 mg die) achieved a complete clinical recovery and HBV-DNA clearance from blood within 8 weeks. The second patient (HBsAg and HBV-DNA seronegative, anti-HBs and anti-HBc positive before treatment) was kept under prophylaxis with lamivudine up to three months after alemtuzumab. Two ...

Dr. J. Barthelow Classen, MD presents compelling evidence linking hepatitis B vaccine and other vaccines commonly used in childhood to the rise in type 1 insulin dependent diabetes. Following is a brief discussion. To access the full article and others, please visit Dr. Classens website.. Discussion. Published data links the hepatitis B vaccine to an epidemic of IDDM (Classen, DC & Classen, 1997). The incidence of type I diabetes in the 0-19 year old age group has been studied since 1982 in Christchurch, New Zealand and a rise in type I diabetes was noted to occur in 1989 (Classen,JB, 1996b) after the initiation of an hepatitis B immunization program. The government of New Zealand introduced a massive Hepatitis B vaccination program in 1988 which was extended to include all children under 16 and over 70% of children were vaccinated within a few years with almost all of the immunization starting after 6 week of life. The initial vaccine was a human blood derived product but was switched to a ...

The use of livers from hepatitis B surface antigen-negative (HBsAg -)/hepatitis B core antibody-positive (HBcAb+) donors in liver transplantation (LT) for HBsAg-/HBcAb- recipients is still controversial because of a lack of standard antiviral prophylaxis and long-term follow-up. We present our 13-year experience with the use of HBcAb+ donor livers in HBcAb- recipients. Patients received prophylaxis with hepatitis B immunoglobulin at the time of LT and then lamivudine daily. De novo hepatitis B virus (HBV) was defined as positive HBV DNA detection. Between January 1999 and December 2010, 1013 adult LT procedures were performed at our center. Sixty-four HBsAg-/HBcAb- patients (6.3%) received an HBsAg-/HBcAb+ liver. All donor sera were negative for HBcAb immunoglobulin M and HBV DNA. The mean follow-up was 48.8 ± 40.1 months (range = 1.2-148.8). Both the patient survival rates and the graft survival rates were 92.2% and 69.2% at 1 and 5 years, respectively. No graft losses or deaths were related ...

Hepatitis B is the most probable life-threatening liver infection that is caused by the hepatitis B virus. This is a major universal health problem. This can cause chronic infection and put people at high risk of death from liver cancer and cirrhosis.. Hepatitis B is a virus that affects the liver. Most people have it for a short time and then get better. It is called acute hepatitis B.. Sometimes this virus causes a long-term infection, named chronic hepatitis B. Over time this could damage your liver. Infants and young kids infected with the virus are more prone to get chronic hepatitis B.. Most of the people with hepatitis B do not know that they have it, because they do not have any indications. If you do have symptoms, you may only experience it like you have the flue.. Symptoms consist of:. ...

Blood and blood products are the main routes through which Hepatitis B virus is transmitted. In fact, only 0.00004 ml of blood is sufficient for transmission. Any technique that allows the transfer of blood or serum from one individual to another is potentially likely to transmit Hepatitis B virus. Hepatitis B infection is especially common amongst IV drug abusers, Many cases occured following blood transfusion before the advent of screening. It is also particularly common amongst homosexuals where the practice of anal intercourse is particularly traumatic and frequently results in bleeding. Acupuncture, tatooing and ear piercing have also led to many reported cases of Hepatitis B infection. Hepatitis B is a known occupational hazard and the risk to health workers following accidental innoculation is 6-20%. Health personnel in renal dialysis units are particularly vulnerable. It has become clear that Hepatitis B virus is not spread exclusively by blood and blood products. The virus is infective ...

|p|Timely public health follow-up is required for acute cases of hepatitis B, including immunoprophylaxis of susceptible contacts. Passive public health follow-up is provided for chronic cases. The majority of cases of hepatitis B virus in VCH are chronic. Positive hepatitis B virus surface antigen (HBSAg) results are reported once only - subsequent positive results do not get reported.   Public Health also works in conjuction with external providers to ensure delivery of prenatal, antenatal, and 7-mos follow-up for infants at high risk of hepatitis B infection.|/p|

Hepatitis B virus (HBV) infection is a global public health challenge. Prevalence of current hepatitis B virus infection in the general population in Uganda is about 10%. Health care workers (HCW) have an extra risk of getting infected from their workplace and yet they are not routinely vaccinated against HBV infection. This study aimed at estimating prevalence of hepatitis B virus infection and associated risk factors among health care workers in a tertiary hospital in Uganda. Data were obtained from a cross sectional survey conducted in Mulago, a national referral and teaching hospital in Uganda among health care workers in 2003. A proportionate to size random sample was drawn per health care worker category. A structured questionnaire was used to collect data on socio-demographic characteristics and risk factors. ELISA was used to test sera for HBsAg, anti-HBs and total anti-HBc. Descriptive and logistic regression models were used for analysis. Among the 370 participants, the sero-prevalence of

Major hydrophilic region in genomic HBV extending from aa99 to aa169, clustered with a highly conformational epitope, is critical to the antigenicity of hepatitis B surface antigen (HBsAg) and may affect the diagnosis of HBV in HBV screening test. So, this study aimed to characterize variants of S gene product of hepatitis B virus (HBV) isolated from patients with overt or occult HBV infection in north-eastern Egypt. The study included sera of two different groups of volunteer blood donors (VBDs), 82 with overt HBV that were positive for HBsAg and anti-HBc and 343 donors negative for HBsAg eligible for donation. Of the latter group, only 44 were positive for anti-HBc. All anti-HBc positive sera were subjected to HBV DNA detection and partial sequence analysis targeting the HBV S gene. HBV DNA was detected in 22.7 % of HBsAg-/anti-HBc + (10/44 patients) and in 90 % of HBsAg + donors (74/82 patients) with significant statistical difference (P = 0.0001). Phylogenetic analysis showed that HBV strains

Subjects in this study demonstrated an overall low level of knowledge about hepatitis B. Vietnamese adolescents were more likely than were other students to identify the definition of hepatitis B, although only about one third were able to do so. Moreover, Vietnamese youth, who have the highest seroprevalence of hepatitis B, were much less likely to identify a critical risk factor for transmission: sexual contact with an infected person.. Respondents who reported having been taught about hepatitis B in school were much more likely to know both the definition of hepatitis B and to correctly identify a source of transmission, lending indirect support to school-based efforts to educate adolescents about hepatitis B. During the year before this study, health education on hepatitis B had been presented to Vietnamese high school and middle school students during informal group sessions as part of an Asian youth health fair. Otherwise, hepatitis B was not a formal component of the schools health ...

Hepatitis B is a bloodborne pathogen disease transmitted by direct contact with blood or body fluids that contain the virus, sexual contact with an infected person, or from an infected mother to her infant during childbirth. The incidence in the United States in 1991 was 7 cases/100,000 population but declined and has remained constant at between 2.5-2.8 cases/100,000 population for the past 3 years. The incidence of hepatitis B in Indiana continues to fall below the national average.. In 2001, 77 cases of acute hepatitis B were reported to the Indiana State Department of Health, matching the previous record low of 1999. One of the reported cases resulted in death. Figure HpB1 shows reported cases of hepatitis B for the five-year period, 1997-2001.. In 2001, rates of acute hepatitis B infection varied with age. The highest age-specific rate in Indiana was found in adults ages 30-39 (2.7) followed by adults ages 20-29 (2.4). Historically, acute hepatitis B rates have been highest in young adults. ...

INTRODUCTION: hepatitis B virus infection is a major global health problem of public health importance. In a bid to control the infection, the Nigerian government in 2004 introduced hepatitis B vaccine into the National Program on Immunization. There are no studies on the prevalence of hepatitis B in adolescent prior to 2004.The study was aimed at determining the seroprevalence and predictors of viral Hepatitis B in Nigerian children aged 11-18 years. METHODS: a cross sectional analytical study was conducted in July 2014.Multi-staged sampling technique was used to select 749 children from six secondary schools in Calabar, Cross River State, Nigeria. Ethical clearance was obtained from the Cross River State Medical Ethical Committee. A validated structured interviewer administered questionnaire was used to obtain information from participants following parental consent. Blood samples were obtained for qualitative detection of HBsAg using rapid chromatographic immunoassays with test kits from ABON

Introduction Occult hepatitis B virus (HBV) infection, so-called occult B infection (OBI), is defined by the recognition of HBV-DNA in the absence of serum hepatitis B surface antigen (HBsAg). The HBV-DNA genome in OBI is fully replication competent and produced in the liver, characteristically with low-level HBV-DNA fluctuations in the bloodstream. The OBI status remains between chronic (HBsAg +) and resolved (anti-HBs +) phases in the natural history of HBV infection. Methods The clinical interest in OBI has increased because of its potential for overt HBV reactivation under immunosuppression as well as for HBV transmission, well established in recipients of blood transfusions and/or organ transplants. Results Given the shared transmission routes for HIV and HBV, earlier reports claimed that OBI was more frequent in AIDS patients. By contrast, the current scenario shows that OBI is negligible in the HIV population. One explanation is that HBV immunization and recall vaccination campaigns have ...

article{de66a93b-1594-4340-b9c4-beaf1b1f71f6, abstract = {Long term follow up of 16 homosexual men and 78 intravenous drug abusers who were chronic carriers of hepatitis B surface antigen (HBsAg) showed fundamental differences between the two groups. Viral replication, expressed by the presence of hepatitis B e antigen, lasted for four years or more in 10 out of 14 (71%) of the homosexual men whereas it was not present in 43 out of 73 (59%) of the drug addicts within one year. This shows a difference in the immunological response between homosexual HBsAg carriers and addicts that is not related to infection with human T cell lymphotropic virus type III. Severe histological damage such as chronic aggressive hepatitis, cirrhosis, or primary liver cancer was found in more than half of the homosexual men who underwent biopsy examinations. In drug addicts chronic persistent hepatitis was a regular finding in the absence of markers of delta infection, but in those addicts infected with the delta agent ...

Background: According to the World Health Organization, Hepatitis B virus (HBV) is considered a major global public health problem. The genetic background may be a crucial etiologic factor in HBV infection and its complications. Interleukin-27 (IL-27) is a newly discovered cytokine encoded by 2 genes (EBI3 and p28). Mutations in the IL-27 gene may lead to altered cytokine production and/or activity and thus modulate individuals susceptibility to HVB infection ...

Typical sequence of serologic markers in patients with HBV infection that progresses to chronicity. In patients with chronic HBV infection, both HBsAg and IgG anti-HBc remain persistently detectable, generally for life. HBeAg is variably present in these patients (Horvat, R. T., and Tegtmeier, G. E. 2007).. Hepatitis B virus (HBV) causes a wide spectrum of manifestations ranging from asymptomatic seroconversion, sub-acute illness with non-specific symptoms (e.g. anorexia, nausea, or malaise) or extrahepatic symptoms, and clinical hepatitis with jaundice, to fuliminant fatal hepatitis. Only 10% of children and 50% of adults will exhibit symptoms. An acute illness may last up to three months with a fatality of 1-2%. In most acute cases HBsAg serum levels are positive initially, resolve and the individual develops anti-HBs which confers immunity.. HBV occurs worldwide, and is endemic in some Asian countries. In Canada the incidence of acute hepatitis B is estimated to be 2.3 per 100,000. In ...

NEWS STORY ON HEPATITIS B VACCINE TO AIR ON 20/20 THIS WEDNESDAY. A national news story on hepatitis B vaccine is scheduled to be aired on ABCs 20/20 program on Wednesday, January 13, at 10 p.m., EST. According to the Centers for Disease Control and Prevention (CDC), the program is likely to focus on alleged adverse events associated with hepatitis B vaccine.. In a letter dated January 8, Walter A. Orenstein, M.D., M.P.H., Assistant Surgeon General, Director, National Immunization Program, CDC, wrote the following:. From interview questions, we surmise that 20/20s story is likely to focus on alleged adverse events associated with hepatitis B vaccine (e.g., multiple sclerosis, chronic fatigue syndrome, optic neuritis, Lupus). We also know that the 20/20 reporters contacted states to learn more about laws requiring hepatitis B vaccination.. To assist health professionals in responding to questions generated by the story, CDC released a message from Dr. Orenstein. The message appears on CDCs ...
