Joan Block, Hepatitis B Foundation Co-founder, Honored for Advocacy Work

A wonderful article (reprinted below) and short video was published last weekend in Phillyburbs.com recognizing the work of Joan Block, the Executive Director and co-founder of the Hepatitis B Foundation. In commemoration of World Hepatitis Day, Joan and Dr. Anna Lok were honored by the Viral Hepatitis Action Coalition of the Centers for Disease Control Foundation, for advocacy work resulting in the protection of medical students from HBV discrimination, and ultimately having HBV recognized as a disability protected under the Americans with Disabilities Act (ADA). This amazing accomplishment is just one of the many successes Joan and the HBF have had over the last 23 years as a result of her tireless efforts and dedication to the mission to help improve the lives of those affected by hepatitis B.

Please visit Phillyburbs.com to access to view the short video where Joan talks about the Foundation’s beginnings and how the HBF has grown from a grass roots effort to the leading national nonprofit for hepatitis B. Joan Block and the HBF truly are the “voice of hepatitis B”.

Read more about the story and the mission of the Hepatitis B Foundation and be sure to visit the HBF website to learn more about hepatitis B and the work of the Foundation.

For more than two decades, the Hepatitis B Foundation has fought to find a cure for the liver disease and advocate for those who have it.

What started as a grass-roots effort of four passionate people has grown into one of the leading nonprofit research and disease advocacy organizations in the United States.

“We are the voice for hepatitis B in the United States,” said co-founder and executive director Joan Block. “There’s still a lot of work to do, but we’ve accomplished a lot in the past 23 years.”

Earlier this year, the foundation’s mission got a boost when the U.S. Department of Justice said hepatitis B patients are protected under federal disability law in a case brought by the foundation against a New Jersey medical school on behalf of two students who were denied admission because they had the disease.

The case earned Block and Dr. Anna Lok, director of clinical hepatology at the University of Michigan Health System, recognition from the Centers for Disease Control Foundation, which honored both women on World Hepatitis Day July 25.

“That award is really being given to the foundation,” said Block, who lives in Doylestown Township. “It’s not me; it’s the work of the foundation. Without the foundation, I honestly don’t know if hepatitis B would even have much on the radar screen. There are very few voices, and we are probably the primary voice at the national level.”

Hepatitis B is an infectious liver disease that can be spread by sexual contact, sharing infected needles or at birth from mother to child, according to the Centers for Disease Control and Prevention. Chronic infection can lead to liver failure and cancer.

Block, her husband, Timothy Block — a researcher and academic who more often serves as the public face of the foundation — and New Hope philanthropists Jan and Paul Witte founded the Hepatitis B Foundation 23 years ago to draw more attention to and develop a cure for the disease, which affects up to 1.4 million Americans.

The couples initially started out to help a local family dealing with the disease. But what they found was little interest from the public health sector in researching a cure. The hepatitis B vaccine has led to dramatically lower rates of infection, and the prevailing, yet incorrect, belief at the time was that the disease infected mainly gay men and intravenous drug users.

“The more we dug, the more we realized there was nothing out there,” Joan Block said. “It was really grass roots, just the four of us in (the Wittes’) kitchen. We had the grand mission of raising a lot of money to start a research effort. That’s really what we needed. But it was hard to raise money when people didn’t know what hepatitis B was.”

Over the years, she said, the foundation has received numerous phone calls from people who believed they were being discriminated against because they have the disease. Some of them were medical professionals.

In 2011, four students contacted the foundation over six months, all claiming they were denied admission to or kicked out of medical and dental schools after discovering they had hepatitis B. All four were Asian Americans who were infected at birth. About half of infected patients in the U.S. are of Asian descent.

“It seemed like an avalanche,” said Block, a registered nurse who taught at Abington’s nursing school.

The foundation and Lok lobbied the CDC to update hepatitis B guidelines for medical professionals and students last changed in 1991. Since that last update, there have been no reports of hepatitis B transmission from medical or dental students, according to the CDC.

The Hepatitis B Foundation also filed a lawsuit on behalf of two students denied admission to the University of Medicine and Dentistry of New Jersey. The school settled with the Department of Justice.

In an added step, the departments of justice, health and human services and education sent a joint letter to the nation’s medical and dental schools about hepatitis B, encouraging them to adopt the CDC guidelines and informing them that people with hepatitis B are protected under the Americans with Disabilities Act.

But the foundation’s advocacy work is far from over. The organization is now lobbying on behalf of servicemen and women who are fighting discharge from the military on the grounds that they’re infected with the disease.

And the foundation’s executive director continues to push for a cure.

“We still want that cure,” Joan Block said. “We’re not satisfied that it’s preventable and controllable. We still have an urgent mission. That has not changed.”

 

Diagnosed With Chronic Hepatitis B? What Phase – HBeAg-Positive Chronic Hepatitis / Immune Reactive / Immune Clearance?

In the last chronic hepatitis B stages blog, we looked at the HBeAg-Positive Chronic Infection (also known as immune tolerant).

At some point the immune system recognizes the hepatitis B virus and the chronically infected person will enter a phase referred to as the  HBeAg–positive chronic hepatitis- (also  known as immune reactive/immune clearance). During this phase blood work will show that you are HBeAg positive, with lower levels of HBV DNA when compared to the HBeAg-positive chronic infection/immune tolerant stage, and increased ALT (SGPT) levels. (Remember, it is not at all unusual for kids to have viral loads in the millions or even billions.) During this “clearance” phase the immune system is actively attacking infected liver cells. This is both good and bad. On the good side, if the immune system is able to “beat” the virus, the person will go through HBeAg seroconversion and lose the HBeAg antigen. This means that HBeAg will go from positive to negative and the HBeAb antibody, or anti-HBe will go from negative to positive.  This results in significant decrease in the hepatitis B virus level, often to an undetectable level, and normalization of ALT/AST liver enzymes and other liver function blood test results. Successful HBe serconversion moves you into the HBeAg-negative chronic infection/inactive carrier phase.

When the immune system activates and starts attacking infected liver cells, it not only kills the virus, but also the host liver-cells. You may not feel any of this, but your ALT (SGPT) and AST (SGOT) lab values will be elevated. These enzymes are released when there is inflammation caused by liver cells that are injured or killed.  Your doctor may see a mild, moderate or high levels of ALT elevation reflecting inflammation in the liver. Ultimately the problem is how much inflammation and liver damage occurs during the process of HBeAg seroconversion. Your doctor will need to carefully monitor liver enzymes, liver function and use non-invasive calculations and diagnostic imaging to get a clearer picture of what is happening with your liver.

It is possible a person will quickly and spontaneously move into and out of the HBeAg-positive chronic hepatitis/immune reactive phase, and with a limited amount of inflammation and liver damage. However, some people may cycle up and down for years with intermittent flares, which are evidenced by ALT elevations which may be as high as 10 times above the upper limits of normal (normal is 35 IU/mL for men and 25 IU/mL for women) when in the immune reactive phase.  While the immune system attacks infected liver cells, viral replication will decrease and ALT levels will elevate as infected liver cells die in the battle.  If successful, the immune system response will result in HBe seroconversion –  losing HBeAg, gaining the HBe antibody, and a decline of the viral load  (HBV DNA) to very low or undetectable levels, and the normalization of ALT/AST and other liver enzyme levels.

Unfortunately, that might not be enough, and the immune system may not be able to put up a big enough fight permitting HBe seroconversion to a less active or HBeAg negative chronic infection /inactive carrier phase. Evidence of this is ALT levels that go back down, and viral replication that goes back up. (Note the above diagram.) This cycling up and down over time will be reflected in lab work if a liver specialist monitors you regularly over time. If you are not having your ALT levels regularly monitored (every few months), then you may miss these cycles of intermittent elevations or flares over time. It is during these elevations that liver damage occurs, and you will likely be completely unaware, unless you have lab work done while liver enzymes are elevated, or you wait until there are symptoms and significant liver damage.

It is during the immune clearance phase when treatment is sometimes recommended. It is true that a chronically infected person will eventually serconvert HBe spontaneously – without treatment, but most liver specialists choose to treat in order to prevent years of ALT elevations and flares and subsequent damage to the liver.

If you appear to be in the HBeAg-Positive Chronic Hepatitis / Immune Reactive phase, be sure to ask your doctor about treatment with first line antivirals such as tenofovir (TAF or TDF) and entecavir.  Don’t be afraid to ask questions about your hep B infection and the health of your liver. Treatment with antivirals greatly reduce liver disease progression and can be lifesaving.

 

Kudos to HBF’s Blog Voted as a “Sexual Health Top 10, Must Read Blog”

The team at Health Express has voted HBF’s blog as one of the “Must Read Blogs of 2013 – Sexual Health Top 10!”  HealthExpress.co.uk is an online clinic that provides support, advice and treatment for common medical conditions that patients do not always feel comfortable talking about. You can take a look at their recommended Top 10 blogs and learn more about them at healthexpress.co.uk.

The accolades from the HealthExpress team are a great opportunity to review transmission of the hepatitis B virus. HBV is transmitted through infected blood and body fluids. This includes direct blood-to-blood contact, unprotected sex, unsterile needles, and from an infected woman to her newborn baby at birth.  Sharing sharp, personal items that may have trace amounts of blood on them such a razors, toothbrushes, nail clippers and body jewelry including earrings, can also spread the virus.  Remember that the HBV virus may live up to a week on a surface resulting in possible transmission through direct blood-to-blood contact. This is why close, household contacts or family members are at greater risk of infection if one or more members are living with HBV. Don’t forget to be sure your tattoo or piercing experience is safe and that the parlor carefully follows infection control practices. Hepatitis B is also 50-100 times more infectious than the HIV virus.

Hepatitis B is also a sexually transmitted disease and is spread through infected semen, vaginal fluids and any blood that may be exchanged as part of a sexual practice – most often through sexual intercourse. In the United States, sexual transmission is the most common mode of HBV transmission and is responsible for 2/3 of acute HBV infections. A common question is “what about oral sex?” In general, oral sex would be considered less risky, but any kind of intimate sharing that may result in the exchange of bodily fluids will present some degree of risk.

So how can you prevent hepatitis B transmission between sexual partners? Fortunately there is a safe and effective hepatitis B vaccine to protect against the spread of HBV.  Get screened for HBV and vaccinate to protect – especially if you or your partner has more than one sexual partner, or if one or more partners is at greater risk.  When in doubt, get screened. Keep in mind that HBV is referred to as a “silent infection” since it may take decades for symptoms to occur. People with chronic HBV may be completely unaware of their infection and inadvertently spread HBV to their partner(s) if precautions are not taken.

Other precautions include practicing safe sex by using a latex or polyurethane condom. A lambskin condom will not prevent the spread of hepatitis B or other viral STDs. Looking for condom details?

A general comment to those with multiple sex partners– We are very fortunate to have a vaccine to protect against the hepatitis B virus. However, practicing safe sex with an effective condom is always advised to prevent the transmission of other infectious diseases that are not vaccine preventable, such as HCV and HIV, along with condom use to prevent the spread of other sexually transmitted diseases. Use common sense. No one wants a sexually transmitted disease, and if you have HBV, you really don’t want a coinfection. It can really complicate your life.

First Clinical Trial Using “RNA Interference” for Hepatitis B Begins

A ground-breaking approach to hepatitis B treatment, which manipulates RNA messengers to halt viral replication, has begun its first human clinical trial. If successful, this approach would be a paradigm shift in treatment, possibly re- placing interferon and antivirals.

In animal trials, reported in the May 2013 journal Molecular Therapy, RNA interference (RNAi) treatment reduced hepatitis B surface antigen (HBsAg) levels to undetectable within 24 hours in mice and the antigen remained undetectable for nearly a month.

RNAi treatment works by destroying or “silencing” the molecular messengers that carry im- portant genetic information to the hepatitis B virus (HBV) antigen/ protein factories. Without the critical information that messenger RNA molecules carry, these antigen factories shut down and HBV reproduction de- clines dramatically.

Early RNAi research found that RNA silencing worked extremely well in the liver, but the challenge has been to create a formula and delivery system to target hepatitis B antigens in liver cells without affecting other important cells.

Arrowhead Research Corp. found that when the small RNA interrupters are linked to cholesterol, they target liver cells extremely well, and the addition of special polymers helps the gene silencing process. Arrowhead designed an intravenous formula, called ARC-520, that is utilized in its Phase 1 trial.

The hope is that when the viral load is dramatically reduced, the body’s immune system can gain the upper hand and eradicate the infection on its own.

In addition to its mouse trial, a similar trial involving an HBV infected chimp with an extremely high viral load also led to rapid reduction in HBV DNA and a 90% reduction in another hepatitis B antigen—the hepatitis B “e” antigen (HBeAg).

The clinical trial of ARC-520 (which uses a Dynamic Polyconju- gate delivery platform and includes two distinct RNA silencing agents that should shut down hepatitis B anti- gen reproduction) in humans is taking place in Melbourne, Australia. It is a randomized, double-blind, placebo- controlled trial. Each group of six healthy volunteers will receive either a placebo intra- venous injection or a single dose of ARC- 520…

World Hepatitis Day in Ghana

Ghanians lined up for a viral hepatitis screening at last year's World Hepatitis Day event in Tamale, Ghana (Northern Region)

HBF is pleased to share World Hepatitis Day plans of our friend Theobald Owusu-Ansah of the Theobald Hepatitis B Foundation in Ghana. The Foundation is also a voting member of the World Hepatitis Alliance. 

On July 28th, 2013, The Theobald Hepatitis B Foundation and the Hepatitis Coalition of Ghana will join the World with one voice to celebrate World Hepatitis Day in Sunyani at Victoria Park. In attendance will be the Chiefs, members of Parliament, District Chief Executives, Municipal Chief Executives, Assembly Members and all the Opinion Leaders of the Region.

The Theobald Hepatitis B Foundation is a non-profit organization whose main aim is to educate and create awareness of hepatitis B and C to the general public, ranging from the causes, and symptoms of viral hepatitis, to preventive measures.

On World Hepatitis Day, the activities will start with an early morning Float with music and dance throughout the principal streets of Sunyani, along with the members and volunteers of the Foundation and the Coalition distributing educational materials to the crowds. These leaflets, posters, banners and stickers are part of the ongoing media blast that will draw the public’s attention to problem of chronic hepatitis B among the people of Ghana.

Free screening and hepatitis B vaccinations will be ongoing throughout the day’s activities. Resource persons will be delivering their messages and educating the general public about viral hepatitis. It is important that the people learn and understand whether or not they are positive or negative for viral hepatitis, and if they are positive, what is next.

The Delegation of the Government and other health care professionals will educate the public on Viral Hepatitis Policies and the way forward. Dieticians will also take the general public through the kind of food and diet one needs to eat, and the importance of avoiding alcohol, in order to defuse the public cry of the cost of prevention and treatment of hepatitis B.

Participating organizations will then take the opportunity to appeal for funds from the government officials and the Chiefs of the region present, in order to enable us to successfully organize our last programme of the year.

At the end of the event, the public will be provided with advice, and directed to seek medical information from qualified health professionals, in order to avoid falling into wrong hands of those trying to sell false cures for those with hepatitis B.

Please join us for our World Hepatitis Day activities in Victoria Park if you are in Sunyani, Ghana.

Experts Describe When to Treat Pregnant Women with Antivirals
Two U.S. hepatitis B experts have crafted guidelines for doctors to use when deciding when to treat pregnant women infected with the hepatitis B virus (HBV) with antivirals in order to safeguard the women’s health and prevent infection of newborns.

More than half of new hepatitis B infections result from mother-to-child (vertical) transmission and despite immediate immunization and administration of HBIG (hepatitis antibodies), about 30% of infants born to women with high viral loads become infected. Additionally, women who want to become pregnant may already be treated with antivirals because of liver damage.  There is little medical guidance on whether treatment is safe over the entire pregnancy.

Does pregnancy worsen hepatitis B? Generally it does not unless the woman has cirrhosis (severe liver scarring.) Studies show a pregnant woman’s viral load generally does not increase over a pregnancy, but after the baby is born and the woman’s hormone levels change (akin to a sudden decline in steroids), some women experience a “flare” and their alanine transaminase (ALT) levels may increase due to moderate liver cell damage. Because of these flares, doctors must monitor new mothers carefully for several weeks after childbirth.

When should pregnant women be treated? Starting in the second or third trimester of pregnancy, antiviral treatment is recommended when women have high viral loads—exceeding 1 million copies per milliliter or 200,000 international units per milliliter. However, if women are already receiving antiviral treatment when they become pregnant, treatment should probably continue over the pregnancy to prevent worsening liver disease.

Which antivirals are safe to use during pregnancy? The experts recommend tenofovir (Viread) in the event the woman continues to need antiviral treatment because this drug has a very low rate of drug resistance, or telbivudine (Tyzeka). Both have been shown to be safe and cause no birth defects when used in pregnant women infected with HIV or HBV.

Hepatitis B and Social Security Disability Benefits

Please welcome guest blogger, Ram Meyyappan, senior editor of Social Security Disability Help as he provides advice on applying for Social Security Disability Insurance or Supplemental Security  Income should your HBV prevent you from working.

Hepatitis B (HBV)  is often referred to as a “silent infection” because those chronically infected may have few or no symptoms, or may not be unaware of their infection for decades. However, over time, the risk of serious liver disease is certainly possible and symptoms can range from mild to severe.  Severe symptoms rarely occur with an acute HBV infection, but can have very serious outcomes.  If your condition is severe to the point that you can no longer continue to work, you may qualify for SSDI (Social Security Disability Insurance) or Supplemental Security Income (SSI) benefits from the Social Security Administration (SSA).

You can learn more about SSDI and SSI here

Hepatitis B and Qualifying for Benefits

When you submit an application for Social Security Disability benefits an adjudicator will review your file and compare your condition with a listing of conditions known as the SSA Blue Book (http://www.ssa.gov/disability/professionals/bluebook/). This Blue Book contains a listing of conditions and qualifying criteria that may qualify an individual for Social Security Disability benefits. Unfortunately Hepatitis B does not have its own listing in the Blue Book. You may still be able to qualify for disability benefits, however, if you are able to prove that you suffer from an associated condition (such as depression) that is included in the Blue Book. Some of the conditions that may qualify an individual for Social Security Disability benefits that are listed in the Blue Book and that may be associated with Hepatitis B include:

  • 5.05 Chronic liver disease
  • 5.08 Unexplained weight loss
  • 5.09 Liver transplant
  • 12.04 Affective disorders

If you are applying for disability benefits based on an associated condition that is listed in the Blue Book, you must provide medical documentation proving that your condition is severe enough to meet the criteria of that specific listing. For example, in the case of chronic liver disease, you must be able to prove that:

  • You are hemorrhaging from esophageal, gastric, or ectopic varices or from portal hypertensive gastropathy and it has resulted in hemodynamic instability and required hospitalization for transfusion of at least 2 units of blood; or
  • You suffer from ascites or hydrothorax that is not attributable to other causes, despite continuing treatment, as prescribed, and that the condition was present during at least 2 evaluations that were at least 60 days apart within a consecutive 6-month period; or
  • You suffer from spontaneous bacterial peritonitis with peritoneal fluid containing an absolute neutrophil count of at least 250 cells/mm3; or
  • You are suffering from end-stage liver disease with SSA CLD scores of 22 or greater.

If you are not suffering from a condition that is listed in the SSA’s Blue Book, you may still be able to qualify for disability benefits under what is known as a vocation allowance. In order to do this, however, you will have to prove that you are unable to perform any type of work activity whatsoever. This can be done through medical findings, laboratory reports and a residual functional capacity form. In the case of Hepatitis B, your condition must be very advanced and severe in order to qualify. Unless you are suffering from end-stage liver disease, you may have a hard time qualifying for benefits based on this condition.

Applying for Social Security Disability Benefits with Hepatitis B

To apply for Social Security Disability benefits, you can apply online at the SSA’s website (http://www.socialsecurity.gov/pgm/disability.htm) or apply in person at your local Social Security office. You will want to make sure that you have all of your medical evidence ready when you go to submit your application for benefits.

It can be very hard to prove that you qualify for Social Security Disability benefits when you are applying based on a condition that is not included in the SSA’s Blue Book. Because of this, you may want to consider retaining the services of a disability attorney prior to submitting your application. A disability lawyer can help you gather the evidence that you will need to prove your case. These attorneys will know which condition, if any, may qualify you under the SSA’s Blue Book or how to prove that you qualify based on a vocational allowance.

Big Thank You to 2 Hep B Heroes

 

HBF would like to thank Hep B Heroes Nina and Richie Kahn. Richie recently ran the Delaware Marathon, and he and Nina used this opportunity to raise money for the Hepatitis B Foundation. Nina and Richie, thank you for your generous donation and your commitment to those living with hepatitis B!

“Back in 2008, I suffered a pretty horrific knee injury running the Philadelphia Half-Marathon. Several years, surgical procedures, and rehabilitation sessions later, I’m running again. So, I figured why not put my stamina to the test by running my first marathon while raising money for a wonderful cause?

On May 12th, I ran the Delaware Marathon to raise money for the Hepatitis B Foundation (HBF). For those of you who haven’t had the pleasure of working with HBF, the foundation is the only national non-profit organization solely dedicated to the global problem of hepatitis B. They are dedicated to finding a cure and improving the quality of life for those affected by hepatitis B worldwide. This commitment includes funding focused research, promoting disease awareness, supporting immunization and treatment initiatives, and serving as the primary source of information for patients and their families, the medical and scientific community, and the general public.

I finished the race in 3:59:23, 218th overall. More importantly, thanks to the generous support of friends, co-workers, and colleagues, we were able to raise nearly $3,000 for the Hepatitis B Foundation. Be sure to check out the Hepatitis B Foundation’s website to learn about the excellent work they do at http://hepb.org/.”

 

 

High HBV Viral Load Tied to Low Serum Vitamin D Levels

An interesting study published in Healio Hepatology:  “High HBV viral load tied to low serum vitamin D levels” discusses the relationship between the HBV viral load and vitamin D levels. In fact is shows seasonal fluctuations of HBV viral load associated with vitamin D levels. Vitamin D has been on the radar for years, but this interesting correlation between HBV virus flucuations and vitamin D levels warrants additional research to investigate how adequate vitamin D levels can positively impact treatment for those living with chronic HBV. Please refer to earlier blogs, Hepatitis B and Vitamin D and Got HBV? Adding Vitamin D to Your Diet for additional information.  As always, please talk to your doctor and have your serum vitamin D levels checked before making any drastic changes to your diet or supplements you may be taking. Don’t forget that vitamin D is the sunshine vitamin, so be sure to keep in mind the impact of the seasons on your levels. 

Patients with chronic hepatitis B who also were vitamin D deficient had significantly higher HBV DNA levels than patients with adequate vitamin D concentrations in a recent study.

In a retrospective study, researchers measured the serum levels of 25-hydroxyvitamin D (25OHD) in 203 treatment-naive patients with chronic hepatitis B seen between January 2009 and December 2012. Patients with 25OHD levels less than10 ng/mL were considered severely deficient, levels below 20 ng/mL were considered deficient, and levels of 20 ng/mL or greater were considered adequate. Patients’ samples were collected upon initial presentation, except 29 participants whose samples were taken at antiviral therapy initiation.

The mean 25OHD concentration for the cohort was 14.4 ng/mL. Forty-seven percent of participants were considered 25OHD deficient; 34% were severely deficient. 25OHD levels were similar between Caucasians (14.38 ng/mL) and non-Caucasians (14.59 ng/mL) (P=.7).

An inverse correlation was observed between levels of HBV DNA and 25OHD (P=.0003). Multivariate analysis indicated that HBV DNA was strongly predictive of low 25OHD levels (P=.000048), and vice versa (P=.0013). Patients with HBV DNA levels less than 2,000 IU/mL had 25OHD concentrations of 17 ng/mL; those with 2,000 IU/mL or higher had concentrations of 11 ng/mL (P<.00001 for difference). Participants who tested positive for hepatitis B e antigen (HBeAg; n=26) had significantly lower 25OHD levels than HBeAg-negative participants (P=.0013); this association was significant only under univariate analysis.

Investigators also noted fluctuations in HBV DNA and 25OHD levels according to season. Significantly lower HBV DNA levels were observed among samples taken during spring or summer than in autumn or winter (P=.01).

“The present study demonstrates a profound association between higher levels of HBV replication and low [25OHD] serum levels in chronic hepatitis B patients,” the researchers wrote. “At least in patients without advanced liver disease … HBV DNA viral load appears to be the strongest determinant of low [25OHD] serum levels. … Future studies to evaluate a therapeutic value of vitamin D and its analogs in HBV infection may be justified.”

U.S. Doctors Failing to Treat Patients Who Need Treatment
Fewer than 50% of patients infected with the hepatitis B virus (HBV) who need treatment get antivirals or interferon from their primary care doctors and fewer than 70% of patients who go to university liver clinics get appropriate treatment, according to research presented at the Digestive Disease Week medical conference held in Orlando in May.

Stanford University researchers conducted a real-life study to see what percentage of 1,976 hepatitis B patients treated in various clinical settings over four years received treatment. They used current medical guidelines when evaluating whether patients received appropriate treatment.
