The Hepatitis B Foundation Participates in Liver Capitol Hill Day, 2013 – A Personal Reflection

Yesterday the Hepatitis B Foundation participated in the American Association for the Study of Liver Diseases (AASLD) annual “Liver Capitol Hill Day” visits. This is a great opportunity to get in front of state Senators and Congressmen in order to make requests known to them. It is also an opportunity to educate. As a constituent, your state representatives are interested in what you have to say. The “Asks” for the day were to support funding for liver related research, prevention strategies, and support of liver patient access to quality medical care.  Specifically, we were asking for NIH funding growth, rather than the 20% cut over the last decade, along with support of government agencies such as the CDC Division of Viral Hepatitis, and the delivery of health care systems and payment policies for patients living with liver diseases.  Prevention is also critical with specific asks for new, one-time hepatitis C testing and screening for hepatitis B for at-risk patients. As we are all aware, budgets are tight and we will all soon feel the effects of the Sequester. Research programs may no longer be funded, or severely cut, public health agencies and programs will be cut, and patients who are currently receiving medical assistance will suffer. For treated patients with HBV, it is essential nothing interrupts the daily antiviral use, and of course HBV and liver cancer prevention through screening, vaccination and surveillance is both necessary and cost effective in the long run.

Due to the Sequester, the day started in a panic for many Hill visitors. I was fortunate to arrive early – a good thing since I waited in a long security line for 45 minutes that wrapped around the building. As Maryland residents, Dave Li and I met with staff from both Senator Ben Cardin’s (D) and Senator Barbara Mikulski’s (D) offices.  Senator Mikulski was recently appointed the Chairperson of the U.S. Senate Appropriations Committee. This means she will have a great deal of influence on budget and spending decisions. We were told that due to the Sequester, the Continuing Resolution (CR) will remain in place for the remainder of the 2013, but Senator Mikulski is optimistic that the FY14 and future funding for the NIH, specifically, will be maintained. As a Maryland Senator, this is extremely important to Sen. Mikulski on many fronts. Senator Cardin has been making visits to agencies in MD, including the NIH, and researchers are frustrated they are unable to do their work.  Both Senator Cardin and Senator Mikulski support federal agencies (such as the CDC, Division of Viral Hepatitis, Public Health Agency etc.) and initiatives that provide care and services to meet the health care needs of Marylanders.  Fortunately this supports the Health and U.S. Health and Human Services (HHS) Viral Hepatitis Action Plan initiatives, since both Senators are supportive of prevention and surveillance initiatives.  Dave and I walked out of our Senate meeting feeling pretty good.

Unfortunately, the outlook was not so optimistic on the House side. We visited staffers from Congressman Chris Van Hollen and Congressman Elijah Cummings offices. Although they are working on budgets, they are meeting with opposition and resigned to deep cuts in their supported programs.  Congressman Cumming’s staffer was pleased to hear an optimistic viewpoint from Mikulski’s office.  Although clearly mixed signals from our House and Senate meetings, we can only hope that Congress will eventually work together and move forward with continued funding of agencies and programs that support those living with liver disease.

Please remember that your state Senators and Representatives have been voted to serve YOU. It is imperative that your voice be heard. If you don’t let them know what is important to you, important programs and agencies will be drastically cut.  You do not need to be a political machine to participate. Don’t know your Representative?   Find your Rep. on-line by putting in your zip code or state to learn who you need to contact. Find your Senator, Governor and Congressmen here. Call the Capitol switchboard’s toll free number at 1-888-876-6242 , or send an email  or letter with your asks, and your personal stories. Be sure your message is clear and concise, and personalize it if you can. You can visit your Representative or Senator when you are visiting Washington, D. C., or in the local, state office. Let your voice be heard – especially during this very difficult time.

High Viral Load, HBeAg Positivity Increased Risk for Mother-to-Infant HBV Transmission

6 Comments

The study published by Healio Hepatology, March 8, 2013 discusses the increased risk of mother-to-infant transmission in HBV positive moms who are HBeAg positive and have a high viral load. Current prophylaxis, where infants of HBsAg+ moms receive the first shot of the HBV vaccine and a shot of HBIG within 12 hours of birth, is successful greater than 90% of the time. However, according to the study, HBeAg+ pregnant moms with a viral load above 107  cp/mL(10,000,000 cp/mL) will transmit the virus to their infant despite prophylaxis. Since a particularly elevated viral load appears to determine the failure of current prophylaxis, the need for additional screening for these women and revised intervention strategies is necessary to prevent transmission to their babies at birth.

If you are a pregnant mom that is HBsAg+, please see a liver specialist for further evaluation to determine your HBeAg status and your HBV DNA viral load. If you are HBeAg + and have a high viral load, (a viral load near the 10,000,000 cp/ml threshold) you will want to talk to your liver specialist to determine if you and your baby would benefit from antiviral therapy in order to prevent transmission of HBV to your newborn. Although there are no official guidelines or recommendations, Registry data shows medications for hepatitis B appear safe during pregnancy. Talk to your doctor to see if this is a good option for you and your baby.

If you are a pregnant woman, please read and print HBF’s Chronic Hepatitis B in Pregnancy, and give it to the doctor who will be caring for you during your pregnancy. Sadly, IOM data shows HBV+ women in the U.S. are not always identified and educated about their HBV, and an opportunity for prophylaxis may be missed despite CDC recommendations that ALL infants receive the first dose of the HBV vaccine prior to hospital discharge.

If you live in a developing country, there may be no guidelines in place that automatically screen pregnant women for hepatitis B. Once again, read and print a copy of “Chronic Hepatitis B in Pregnancy” for your doctor. Insist you are screened for HBV, and if you are HBsAg+, please be sure prophylaxis will be available at the hospital where you will give birth to your baby. If you find you are HBeAg+, with a high viral load, please speak to a liver specialist to see if an antiviral is an option for you to prevent HBV transmission to your baby. Don’t’ forget to have your baby tested at 18 months to ensure your baby is HBV free.

*Please note you can convert copies per milliliter (cp/ml) to IU/mL for the article below using WHO’s international standard where 1 IU/mL = 5.2 copies/mL. Please ask your doctor or your lab if you have specific questions regarding the conversion.


Infants born to mothers with a high hepatitis B viral load, particularly those positive for hepatitis B e antigen, are at high risk for contracting hepatitis despite immunoprophylaxis, according to recent results.

Researchers evaluated 303 mother-infant pairs in which mothers tested positive for hepatitis B surface antigen (HBsAg). Maternal viral load and hepatitis B e antigen (HBeAg) status were determined, and children were tested for HBsAg at ages 4 to 8 months (n=250) and/or 1 to 3 years (n=53 for an initial test; n=183 for a follow-up test). All children received HBV vaccine within the first week of birth and at 1 and 6 months, with a 100% completion rate; children born to mothers who tested positive for HBeAg received hepatitis B immunoglobulin within 24 hours of birth.

HBeAg-positive mothers (81 cases) had higher viral loads than those who did not (7.4 ± 1.9 log10 copies/mL vs. 2.7 ± 1.4 log10 copies/mL; P<.0001 for difference). Chronic HBV infection was identified in 10 children, all born to HBeAg-positive mothers with high viral loads (range 6.5-9.5 log10 copies/mL), and all with the same HBV genotypes and subtypes as their mothers.

Investigators identified a significant association between maternal viral load and a child’s risk for infection via multivariate analysis, after adjusting for factors including age; birth type; infant gender, weight and gestational age, and feeding practices (adjusted OR=3.49; 95% CI, 1.63-.7.48 per log10 copy/mL increase). Predictive rates for maternally transmitted HBV infection were found to be statistically significant at 7 (6.6%; P=.033), 8 (14.6%; P=.001), and 9 (27.7%; P<.001) log10 copies/mL.

“High maternal viral load is the most important factor causing maternally transmitted HBV infection, and is significantly correlated with maternal HBeAg status,” the researchers wrote. “Our predictive model including multiple risk factors showed that children with a maternal viral load above 10,000,000 to 100,000,000 copies/mL (or would have a significant risk of infection despite immunoprophylaxis. Our data provide important information for the rational design of future screening and intervention strategies to further reduce maternally transmitted HBV infection.”

Hepatitis B Advocacy

Justice Department Settles with the UMDNJ Over Discrimination Against People with Hepatitis B

1 Comment

Direct from the Department of Justice (see below), the first DOJ settlement of an American with Disabilities Act (ADA) case involving people with hepatitis B was announced.  The Hepatitis B Foundation is proud to have played a critical role in successfully advocating for these students who suffered from discrimination as a result of chronic hepatitis B infection.

You may recall an earlier story posted both in the HBF Spring Newsletter, 2012 and the HBF’s Hep B Blog, “Dreams on Hold – A personal story of an aspiring medical student .“ This was one of four cases that spurred the HBF into action on behalf of these students and their rights.

July 2011, a meeting was convened by the CDC, with the HBF and others, resulting in the July 2012 CDC update “Recommendations for the Management of Hepatitis B virus-Infected Health Care Providers and Students. ”These recommendations were cited in the DOJ statement and clearly contributed to the DOJ settlement on behalf of people living with chronic HBV eliminating them from being excluded or discriminated against due to health issues. Since all applicants are from the Asian American Pacific Islander (AAPI) community, which accounts for more than 50% of Americans living with chronic HBV, The DOJ assures that the Civil Rights Division is committed to ensuring discrimination does not occur in this community as a result of this disability.  On behalf of those living with HBV, the HBF applauds this decision by the DOJ. 

The Justice Department announced today that it has reached a settlement with the University of Medicine and Dentistry of New Jersey School (UMDNJ) under the Americans with Disabilities Act (ADA).   The settlement resolves complaints that the UMDNJ School of Medicine and the UMDNJ School of Osteopathic Medicine unlawfully excluded applicants because they have hepatitis B.   This is the first ADA settlement ever reached by the Justice Department on behalf of people with hepatitis B.In 2011, the two applicants in this matter applied and were accepted to the UMDNJ School of Osteopathic Medicine, and one of them was also accepted to the UMDNJ School of Medicine. The schools later revoked the acceptances when the schools learned that the applicants have hepatitis B.   The Justice Department determined that the schools had no lawful basis for excluding the applicants, especially because students at the schools are not even required to perform invasive surgical procedures, and that the exclusion of the applicants contradicts the Centers for Disease Control and Prevention’s (CDC) updated guidance on this issue.

According to the CDC’s July 2012 “Updated Recommendations for Preventing Transmission and Medical Management of Hepatitis B Virus (HBV) – Infected Health Care Workers and Students,” no transmission of Hepatitis B has been reported in the United States from primary care providers, clinicians, medical or dental students, residents, nurses, or other health care providers to patients since 1991.

“Excluding people with disabilities from higher education based on unfounded fears or incorrect scientific information is unacceptable,” said Thomas E. Perez, Assistant Attorney General for the Civil Rights Division.   “We applaud the UMDNJ for working cooperatively with the Justice Department to resolve these matters in a fair manner.”

“It is especially important that a public institution of higher learning – especially one with a mission to prepare future generations of medical professionals – strictly follow the laws Congress has enacted to protect from discrimination those people who have health issues,” said U.S. Attorney for the District of New Jersey Paul Fishman. “The remedies to which the school has agreed should ensure this does not happen again.”

Under the settlement agreement, the UMDNJ must adopt a disability rights policy that is based on the CDC’s Hepatitis B recommendations, permit the applicants to enroll in the schools, provide ADA training to their employees and provide the applicants a total of $75,000 in compensation and tuition credits.

Both of the applicants in this matter come from the Asian American Pacific Islander community. The CDC reports that Asian American Pacific Islanders (AAPIs) make up less than 5 percent of the total population in the United States, but account for more than 50 percent of Americans living with chronic Hepatitis B.   Nearly 70 percent of AAPIs living in the United States were born, or have parents who were born, in countries where hepatitis B is common. Most AAPIs with Hepatitis B contracted Hepatitis B during childbirth .   The Civil Rights Division is committed to ensuring that this community is not subjected to discrimination because of disability.

Title II of the ADA prohibits state and local government entities, like the UMDNJ, from discriminating against individuals with disabilities in programs, services, and activities. State and local governments must also make reasonable modifications in policies, practices, and procedures when the modifications are necessary to avoid discrimination on the basis of disability, unless those modifications would result in a fundamental alteration.

More information about the Civil Rights Division and the laws it enforces is available at the website www.justice.gov/crt.  More information about the ADA and today’s agreement with UMDNJ can be accessed at the ADA website at www.ada.gov or by calling the toll-free ADA information line at 800-514-0301 or 800-514-0383 (TTY).

HBsAg Levels Linked with Fibrosis in HBeAg-Positive Patients

Below is a publication from “Healio Hepatology, February 21, 2013 – HbsAg Levels Linked with Fibrosis in HBeAg-Positive Patients” , showing the correlation between HBsAg and HBV DNV virus levels and the risk of moderate to severe fibrosis in HBeAg positive patients.

Patients with hepatitis B who tested positive for hepatitis B e antigen were at increased risk for moderate-to-severe fibrosis with lower levels of hepatitis B surface antigen in a recent study.

Researchers evaluated serum samples and liver biopsy results from 406 treatment-naive patients with chronic hepatitis B. HBV genotype and hepatitis B e antigen (HBeAg) status were recorded along with levels of HBV DNA and hepatitis B surface antigen (HBsAg).

HBeAg-positive patients (n=101) had a higher mean fibrosis stage than HBeAg-negative patients (1.86 ± 1.18 vs. 1.40 ± 0.99; P<.001) and had greater levels of HBV DNA (7.06 ± 1.71 vs. 4.12 ± 1.67)and HBsAg (4.24 ± 0.9 vs. 3.53 ± 0.92) (P<.0001 for both). Investigators observed strong correlations between HBV DNA and HBsAg levels (r=0.44; P<.0001) and between fibrosis severity and HBsAg levels (r=0.43; P<.0001) among HBeAg-positive patients, but not among HBeAg-negative participants.

HBeAg-positive patients with moderate-to-severe fibrosis had lower HBsAg (3.84 ± 1.01 vs. 4.63 ± 0.58; P<.0001)and HBV DNA levels (6.47 ± 1.81 vs. 7.62 ± 1.40; P<.001) than those with mild or no fibrosis. HBeAg-positive patients with genotypes B, D or E had significantly higher HBsAg levels than HBeAg-negative patients, along with higher HBV DNA levels regardless of genotype.

Modeling analysis established an HBsAg cutoff of 3.85 log IU/mL-1 with a theoretical sensitivity of 100%, specificity of 86% and NPV of 100% for predicting moderate-to-severe fibrosis among HBeAg-positive patients with genotypes B or C. Investigators noted that the small cohort size used to establish this cutoff requires further validation to be clinically useful.

“To our knowledge, the current study is only the second to associate an HBsAg cutoff with the prediction of fibrosis severity in CHB patients,” the researchers wrote. “It will be of considerable interest to see whether the serum HBsAg and HBV DNA levels in the patients infected with different genotypes are significantly different from the mean values of the overall HBeAg-positive group, and if they will require the development of genotype-specific cutoffs, or whether a single cutoff is applicable to all HBV genotypes.”

HBV Genotype C Carries Greater Risk for HCC Than Other Genotypes

Below is a publication from “Healio Hepatology, January 23, 2013 –HBV Genotype C Carries Greater Risk for HCC Than Other Genotypes“, showing the risk of hepatocellular carcinoma among the different hepatitis B genotypes based on a meta-analysis of 43 studies. There are 8 identified HBV genotypes ranging from genotypes A through H. These different genotypes are concentrated in distinct geographic areas of the globe, and may influence the course of disease, as noted below with the greater risk of liver cancer for those with genotype C. 

Patients with hepatitis B genotype C are more likely to develop hepatocellular carcinoma than patients with other HBV genotypes, according to recent results.

Researchers performed a meta-analysis of 43 studies (34 cross-sectional, four case-control, four prospective or retrospective cohort studies and one randomized controlled trial) published between 1999 and 2010 assessing the risk for hepatocellular carcinoma (HCC) across the major genotypes of hepatitis B.

Analysis included data on 14,545 patients with HBV, with 517 cases of genotype A, 4,417 of B, 7,750 of C, 1,506 of D, 57 with A and D in combination and 298 with other and/or mixed genotypes. There were 2,841 patients with HCC across all studies.

In 33 studies comparing genotypes B (n=4,417) and C (n=6,060), HCC was significantly more common among participants with genotype C (25% of patients vs. 12%), with an OR of 2.05 (1.52-2.76). Patients with genotypes A (n=517) and D (n=1,506) were at similar risk for HCC across 12 studies (14% for A vs. 11% for D, OR=0.94, 0.67-1.32). Patients with genotype C (n=1,659) were at significantly higher risk than those with genotypes A or D (n=1,403) in 10 studies (30% vs. 7%, OR=2.34, 1.63-3.34). Analysis of HBV subgenotypes Ce (n=1,440) and Cs (n=715) in eight studies indicated a similar risk for HCC between subgenotypes (OR=1.13, 0.76-1.67) (95% CI for all).

“Genotype C HBV is associated with a higher risk of HCC than genotypes A, B and D HBV based on studies largely observational,” the researchers wrote. “This partly explains a higher risk of HCC among patients in Southeast Asia where genotype C HBV is prevalent. Patients infected with genotype C HBV, which is often associated with more active liver disease and higher risk of liver cirrhosis, should be closely monitored for HCC development and considered for antiviral therapy.”

Checking In On Your Hepatitis B Related 2013 Resolutions

2 Comments

It’s week two of 2013.  How are your New Years’ Resolutions going?  When you were making your resolutions, did you consider hepatitis B specific New Year’s resolutions?  Here are a few ideas…

  • Organize your hepatitis B lab data and make a table with the date of the blood draw and the associated blood test results. You’ll want to start by requesting copies of all of your labs from your doctor. Then you can generate data tables using Excel, Word or a pencil and paper table for your charted data.  It will help you visualize your HBV over time, and you may find your doctor likes to see both the lab results and your table of results.
  • Generate a list of questions for your next appointment with your liver specialist.  People get nervous anticipating what their doctor might say about their health. It is very easy to forget those important questions, so be sure to write them down. If the option is available, have a family member or friend attend the appointment with you. That will allow you to pay closer attention while your friend or family member takes notes for you.
  • Avoid the use of alcohol. Hepatitis B and alcohol is a dangerous combination. An annual toast to the New Year? Sure. Drinking daily, weekly or even monthly? Not a good idea.  Binge drinking? Dangerous. A recent study shows an increased risk for liver cancer among cirrhotic patients with HBV. Don’t let it get that far. If you have HBV and you are still drinking alcohol, seek the help you need to stop.
  • Exercise. Many people think that having a chronic illness precludes them from exercise. This is rarely the case, but if you have concerns, talk to your doctor. If you consistently exercise, keep up the good work. If you don’t, please start slowly and work your way up to a more strenuous routine, and follow general physical activity guidelines for adults. Join a gym or find an exercise buddy. Don’t compare yourself to others and work at your own pace. Set realistic workout goals. You don’t need to run a marathon. Brisk, daily walking is great, too. You may find that you experience both physical and emotional benefits, and if you exercise with friends, you’ll also benefit socially. Clinical and experimental studies show that physical exercise helps prevent the progression of liver cancer and improves quality of life. Get moving. It’s good for your overall health and specifically your liver!
  • Maintain a healthy weight by eating a well-balanced diet. This is a favorite on the New Year’s Resolution list for just about everyone with or without HBV. You can’t prevent or cure HBV with a healthy diet, but it does help, and it helps prevent additional problems like the onset of fatty liver or diabetes. If you’ve been following trending health problems, then you are well aware that fatty liver disease and type 2 diabetes are huge problems in the U.S. and are growing issues globally. Both fatty liver disease and type 2 diabetes can often be prevented with a healthy diet and regular exercise. If you are overweight, or make unhealthy choices, make a commitment to change this year. Start by avoiding fast foods, and processed foods. Cut down on fatty foods. Reduce the amount of saturated fats, trans fats and hydrogenated fats in your diet. Saturated fats are found in deep fried foods, red meats and dairy products. Trans and hydrogenated fats are found in processed foods. The liver stores excess dietary fat, and which can eventually lead to fatty liver disease. A fatty liver slows down the digestion of fats. If you have hepatitis B, you want to avoid any additional complications that may arise with fatty liver disease. Diabetes and HBV together can also be very complicated.  Your doctor won’t mind if you try to avoid “white foods”, or foods that that are white in color and have been processed and refined. This includes foods like white flour, rice, pasta, bread, crackers, cereal, simple sugars and high fructose corn syrup.  (Feel free to eat plenty of white cauliflower, turnips, white beans, etc) Avoid sugary treats and drinks. So what should you eat? Eat plenty of fresh vegetables, fresh fruits, whole grains and lean meats.  Go back to the basics! If you have specific questions about your diet, be sure to talk to your doctor.
  • Don’t worry, be happy… Easy to say, but not so easy to accomplish. Anxiety and depression associated with a chronic illness are challenging problems that may be short term, or can worm their way into nearly every aspect of your life. They can even create physical symptoms that may be confusing and may result in even more worry. Please talk to your doctor if you believe your anxiety or depression is something you are unable to manage on your own. Consider joining a support group where you can talk to others facing the same challenges. Personally I found the Hepatitis B Information and Support List a wonderful source of information and support. Chronic illness can feel very lonely – especially with a disease like HBV that has a stigma associated with it. Find a trusted confident with whom you can share your story.

Aspirin Use Associated With Lower Risk of Developing Hepatocellular Carcinoma and Dying of Chronic Liver Disease

3 Comments

HBF welcomes special guest bloggers, Vikrant V. Sahasrabuddhe, M.B.B.S., M.P.H., Dr.P.H and Katherine A. McGlynn, Ph.D, M.P.H. both researchers at the National Cancer Institute of the NIH, and study authors of the recent Journal of the National Cancer Institute publication.

Hepatocellular carcinoma (HCC) is the most common type of liver cancer.  New cases of HCC and deaths related to HCC have been increasing in the United States since the 1980s.  Most cases of HCC occur in individuals with chronic liver disease (CLD).  CLD is caused by chronic inflammation related to viral infection, excess alcohol consumption or other causes.  While HCC is relatively rare in the U.S., occurring in fewer than 10 per 100,000 persons per year, CLD is more common.  Unfortunately, CLD is among the top 10 causes of death in adults between the ages of 45 and 75 years.

In a new study from the National Cancer Institute, researchers investigated whether reduction of inflammation, through the use of non-steroidal anti-inflammatory drugs (NSAIDs) such as aspirin, could reduce the risk of developing HCC or death due to CLD. The study was published in the Journal of the National Cancer Institute on November 28, 2012.

The researchers studied a cohort of over 300,000 men and women between the ages of 50 and  71 years who were enrolled in the NIH-AARP Diet and Health Study.  Aspirin and non-aspirin NSAID (for example Advil, Motrin) use was compared among persons who developed HCC or died from CLD and those who did not develop these outcomes.  In all, 250 study participants developed HCC and 428 died from CLD.  Almost three-fourths of the participants reported using aspirin and approximately one-half reported using non-aspirin NSAIDs.

The study found that participants who reported taking aspirin were 41% less likely to develop HCC, and 45% less likely to die from CLD than those who did not take aspirin. Use of non-aspirin NSAIDS did not reduce the risk of developing HCC, but did reduce the risk of dying from CLD by 26%. The researchers note that additional studies will be required to confirm these findings.

While this study will not lead to any immediate changes in clinical practice, it raises interesting new questions on the role of inflammation in risk for HCC.  Although the researchers took into consideration the effect of alcohol intake (a major risk factor for HCC) as well as smoking and body mass index, the study had no information on hepatitis B virus (HBV) or hepatitis C virus (HCV) status of the study participants.  In addition, NSAID use was only measured for the past 12 months, and the study had no information on the indication, duration or dose.  To partially overcome such limitations, results were analyzed after excluding participants who reported hypertension or cardiovascular disease at the beginning of the study. Those individuals might be taking a low-dose aspirin for a longer duration for the prevention of cardiovascular disease. The results were similar after excluding these participants, which suggests that the main results are likely valid regardless of the indication, duration or dose of aspirin.

The study is the largest population-based study to date to assess development of HCC and risk of death due to CLD in relation to NSAID use.  HCC and CLD involve chronic, long-term inflammatory changes in liver cells, which are caused by enzymes such as cyclooxygenases (COX).  One of the primary ways that NSAIDs modulate the risk of chronic inflammation is by stopping or inhibiting the action of COX enzymes; thus inflammatory changes that contribute to the development of CLD and HCC are reduced.  It is also speculated that aspirin may have other anti-inflammatory mechanisms.  NCI researchers are investigating these hypotheses through basic and translational research studies, as well as assessing the risk of developing HCC and dying of CLD in association with NSAID intake in other epidemiologic studies.

Editorial Comments by W. Thomas London, HBF Senior Medical Advisor

In previous blogs I reported that several drugs commonly used to treat or prevent diseases or conditions other than liver cancer or chronic liver disease may also prevent these serious liver diseases.  These included propranolol used to reduce pressure in the portal vein; metformin used to treat diabetes; and statins for the lowering of cholesterol and reducing the risk of heart disease.

The above report adds aspirin to this list, but people with chronic hepatitis B or C should not begin taking aspirin immediately.  Aspirin may cause serious bleeding that is sometimes fatal.  In order for blood to clot, platelets (cell fragments in blood) must clump.  One of aspirin’s actions is to prevent platelets from aggregating (clumping). This action may be the main reason that regular aspirin may prevent heart attacks. Patients with CLD are already at risk of developing serious bleeding.  The take home message is that patients with chronic hepatitis B or C should consult their doctor before taking aspirin or any other drug.

Do you know the stage or phase of your chronic hepatitis B infection? Quite often people may refer to themselves as “hepatitis B carriers”. This statement by itself does not say anything about your chronic hepatitis B infection except that you are someone who tests positive for hepatitis B, and that you are HBsAg positive.

The names of the stages or phases of HBV may vary with the liver society or over the years, but they reflect the natural history of the virus. It can be helpful for your doctor to determine if you are in the immune tolerant, immune active or clearance phase, the inactive carrier phase, have developed HBe negative chronic hepatitis B, or if you are in an HBsAg negative phase. It may take a few months or even half a year to accurately determine the phase, and then your doctor can talk to you about possible treatment options and whether or not treatment would benefit you at this time.  Remember, hepatitis B is typically not an emergency, so try to relax with the process knowing you may not have immediate answers.

If you are acutely infected, you also follow the natural course of the virus in a matter of months (clearance of an acute HBV infection within 6 months is considered an acute hepatitis B  infection). However, at the end of 6 months, those acutely infected will have a resolved infection, and will no longer be HBsAg+. If you are chronically infected, you will pass through many of these phases too, but unfortunately you will likely never get to an HBsAg negative or resolved phase.  The journey from phase to phase is different for each person and the time it takes to move through these phases varies along with the amount of liver damage that occurs.

The importance of a good liver specialist or knowledgeable doctor  cannot be over emphasized. These stages and phases may seem simple to understand, but not everything is black and white. There are often “gray areas” between phases  or time between phases where bloodwork and other diagnostic data must be carefully monitored. Results vary with the patient. New evidence indicates there may be more damage occurring during this gray area than originally thought. There may be a missed opportunity for treatment during this time.

The importance of being actively involved in your hepatitis B care can not be overstated. Tracking your lab data over time and putting it into an excel spreadsheet or graphing the data may help you understand what is happening with the virus and may even be helpful for your doctor, so don’t forget to request copies of all lab results. You are more in control than you think. Get involved with your care!

Once you have confirmed that you have chronic hep B, you need further testing to determine your HBeAg status. Those with chronic hepatitis B  are either HBeAg positive or negative. If you are HBeAg positive, you have a higher hepatitis B viral load/HBV DNA and are more infectious to others. People who are HBeAg positive are either in the immune tolerant stage or the immune clearance stage or in a gray zone. Repeated labs over time will help clarify this for your doctor.

If you are in the immune tolerant stage, you are HBeAg positive and have a high viral load. You will have normal or very mildly elevated ALT (SGPT) levels and mild or no inflammation or damage to the liver. This is very common with chronically infected young children who may have viral loads in the millions or even billions. During this time the virus is actively replicating in the liver, but the immune system has not recognized the virus so it is not trying to kill the infected liver cells. It is not the replication of the virus that kills liver cells, causing liver damage, but it is the response of your immune system to these infected liver cells.

During the immune tolerant phase the virus is happily replicating, completely unchecked by the immune system, which accounts for the high viral load and lack of liver damage during this time. People in the immune tolerant phase may remain in this phase for a couple of years, or it may be decades.  Treatment is not typically recommended during this phase.  However, for those that have been in this phase for decades, treatment is something likely  recommended by a  liver specialist. There is also the concern that a person may be in a gray zone where ALT elevations and subsequent liver damage may be occurring but may be missed. This emphasizes the need for very careful monitoring by a knowledgeable doctor and the possible discussion for treatment.
