A Look to the Future

Introduction

Hepatitis C is a major global health problem. The World Health Organization estimates that over 170 million people are infected with the hepatitis C virus (HCV) worldwide with 3 to 4 million people newly infected each year.1 Yet, hepatitis C is largely a preventable disease. Prevention requires multilevel education programs, rigorous efforts to protect the blood supply, and major intervention programs for at-risk populations such as intravenous (IV) drug users.

Despite significant advances over the past decade in hepatitis C diagnosis and treatment, there is still far more we do not know about HCV than we do know. Research is being conducted on several fronts in the race to gain control over the virus. Advocates are working diligently to raise public awareness and provide information to the millions of people infected with HCV. Health care providers from all disciplines are looking for better ways to treat people living with hepatitis C.

So, where do we go from here?

Education and Awareness

Despite the fact that most new cases of hepatitis C are preventable, the disease continues to spread globally. Many consider the worldwide HCV prevalence rate to be grossly underestimated. For example, current estimates for the United States do not include incarcerated persons, homeless people, IV drug users, and probably many others who do not participate in the mainstream health care system. Even if current figures are underestimated, they are staggering in terms of the number of people living with HCV, and clearly demand the attention and intervention of public health professionals and advocates worldwide.

Multilevel education, public awareness, and effective, affordable early testing are essential for disease prevention. When prevention fails, effective treatment is imperative.

The federal government is responsible for educating citizens of the United States about communicable diseases such as hepatitis C. The Centers for Disease Control and Prevention (CDC) is the principal agency managing this task. However to date, much of the HCV education and awareness in the U.S. has been accomplished not by governmental agencies, but through the many grassroots hepatitis C organizations and support groups around the country. Why is this the case? Hepatitis C is essentially an "unfunded epidemic," meaning neither the federal government nor the private sector has earmarked funds for combating this growing public health problem. Remarkably, many decision-makers are still unaware of the magnitude and severity of the hepatitis C epidemic currently threatening the health of hundreds of thousands of Americans. The seriousness of the HCV epidemic and the widespread suffering it is causing must become common knowledge if adequate funding to address this disease is to be obtained.

Both government and private funding are desperately needed to support HCV public awareness campaigns. Many grass roots organizations that conduct the majority of hepatitis C education and awareness programs are funded solely by monies from pharmaceutical companies that manufacture drugs used to treat hepatitis C. While this had caused some people to mistrust the provided information, without this funding, public awareness about hepatitis C would be even less than it currently is.

HCV Research

Remarkable advances in medical research have been made during the past six decades. Each decade seems to bring advances even more rapidly than the one before. Computer technology has been an incredible boon to the advancement of medical research, especially with respect to viral illnesses. Computer modeling of viral genomes has allowed scientists to carefully target and attack specific patterns of viruses. As our knowledge increases and pieces of the puzzle are put in place, a more complete picture is revealed.

We have learned a lot about HCV since it was first identified in 1989. But we are far from having a thorough and complete understanding of the virus. The factors that lead to persistent HCV infection are still poorly understood as are many of the mechanisms that contribute to disease progression, treatment response, and the relationship of HCV to liver cancer. Until additional information is available, we must do the best with what we have. We currently have treatments that work for some, but not all people with HCV. Some antiviral therapies offer the possibility of viral clearance, but may cause significant discomfort during treatment. Other therapies may improve quality of life, but offer no potential for viral clearance. As we look to the future, we hope for continued progress in both the treatment and prevention of HCV.

HCV and the Immune System: Is It the Virus or the Host?

Every day, HCV researchers around the world ponder the same questions.

Why do some people infected with HCV develop acute hepatitis that quickly resolves, while others develop chronic hepatitis?
How does HCV infect the cell?
Why do many people go on to develop cirrhosis and/or liver cancer as a result of chronic HCV infection, while others do not?
Why do some chronically infected patients have only mild disease with few symptoms while others experience severe symptoms and disability as a result of the disease?

The ability of the hepatitis C virus to reproduce itself (a process called replication) is staggering. In one day, in one HCV-infected person, there may be more copies of the virus produced than there have been humans on Earth since civilization began! Considered another way, an HCV viral particle can replicate roughly 600-900 generations each year. By comparison, it is estimated there have been only 300 generations of humans on Earth since civilization began. The numbers are so large, it is almost impossible to comprehend them.

Virologists (scientists who study viruses) generally believe characteristics of the hepatitis C virus are primarily responsible for the harm caused by chronic infection. However, many immunologists (scientists who study the immune system) conducting HCV research have a different thought. They believe limitations of the host's immune system are primarily responsible for the severe consequences some people experience in response to HCV infection. Western researchers are studying people who spontaneously clear HCV to identify regions of the virus particle that may be involved in triggering a specific and successful immune response. This work is providing potential targets for the development of vaccines that may be used to prevent or treat HCV infections.

In the end, most HCV researchers agree that both the virus and the host's immunological capabilities play a role in the natural history of the disease in any given person.

Research Frontiers

The federal government funds the majority of clinical and scientific research conducted in the U.S. Areas of HCV research currently being funded through the National Institutes of Health (NIH) include:

development of accurate, cost-effective alternatives to liver biopsy
natural history of HCV

Why do some sustained responders to interferon-based treatment still show signs of chronic infection?
Why do some people progress to cirrhosis while others do not?
Why do some people develop liver cancer after long-standing HCV infection?
What factors influence the rate of disease progression?

immune response HCV

What roles do antibodies have in response to HCV?
What roles to immune cells have in response to HCV?
How does the immune system interact with HCV to cause or limit damage done by the virus?

anti-HCV therapy

Can we develop an effective viral "cocktail" (a mixture of antiviral drugs) for HCV similar to the cocktails currently used to treat HIV/AIDS?
How can we improve upon current interferon-based therapy?
Are there other mechanisms can we use to control and/or eliminate HCV?

liver transplantation

How can we improve upon current transplantation successes rates?
Are there alternatives to transplantation?
How do we protect transplanted livers against reinfection with HCV?
Continue research to perfect and improve success rates for living donor liver transplantation.


Medical researchers around the world are making great strides in all areas of hepatitis C research. A few short years ago, people treated with interferon-based therapy had only a 12% chance of achieving a sustained response. Today, approximately 50% of people treated with pegylated interferon plus ribavirin are sustained responders. Response rates may be as high as 80% among for patients with specific genotypes using currently available interferon-based therapy.


Complementary and Alternative Medicine (CAM) Research

The use of complementary and alternative medicine (CAM) treatment approaches is common in many countries of the world such as China and India. CAM use is becoming increasingly popular in western countries as well. This is particularly true among people with hepatitis C. Frustrated by the inability of western medicine to uniformly clear the virus in all those who are treated, many people have turned to CAM therapies. Much of upsurge in interest in these therapies has been facilitated by easy access to information via the Internet. However, there are concerns about the use of CAM therapies among people with chronic hepatitis C.

The National Center for Complementary and Alternative Medicine (NCCAM) was established by NIH in 1998. NCCAM's functions are:

to explore complementary and alternative healing practices in the context of rigorous science,
educating and training CAM researchers, and
disseminating authoritative information to the public and professionals.

NCCAM's vision is, "to advance research to yield insights and tools derived from CAM to benefit the health and well-being of the public, while enabling an informed public to reject ineffective or unsafe practices."2

Research to establish the safety and efficacy of various CAM therapies for a variety of ailments is a priority for NCCAM. Clinical trials are needed to establish the actions of herbs and nutritional supplements in the body. While NCCAM is conducting research on some herbal therapies and other CAM practices, but they cannot possibly look into all of the thousands of products currently available. According to NCCAM, there has been only limited research on hepatitis C and alternative treatments (see Figure 1).3
 

Figure 1: Amount of Rigorous Research About Hepatitis C

3-Extensive Research: Numerous high quality, scientific studies have been done, including clinical trials and other research published in major peer-reviewed journals. Reliable scientific information is available.

2-Some Research: Some good quality, scientific studies have been published in peer-reviewed journals. Some reliable scientific information is available.

1-Limited Research: A small number of scientific studies have been done, but few have been published in peer-reviewed journals. Some scientific information may be available.

0-No Research: No scientific studies have been done. No scientific information is available.
 

Notes:
The above levels of research are based on the amount of published, rigorous clinical research conducted or sponsored by NCCAM, other Institutes and Centers of NIH, and other biomedical research institutions in the United States and internationally.
 

Product manufacturers and other proponents of CAM must get involved in funding clinical trials that will allow a more careful definition of the risks and benefits of these products and services. While it is important that medical research be scientifically sound, many people question the need for randomized, double-blind, controlled clinical trials for complementary therapies to establish reliable clinical information. Randomized, controlled trials are very costly and time-consuming. While it is true that research on CAM therapy can be a compromise, the same is also true of western research. The best information will come when there is true collaboration between CAM and western practitioners.

Until research data are available on the efficacy and safety of CAM approaches, few western doctors are willing to recommend them. Often, people interested in using these approaches must seek information on their own. Unfortunately, a significant amount of the information available on the Internet and from other sources is unreliable, inaccurate, and sometimes, deliberately misleading. The lack of easily accessible and reliable information was the primary reason we decided to write Hepatitis C Choices, to give people accurate information upon which to base their treatment decisions. If you are considering using CAM products, you should use the same precautions you would with a prescription medicine. Just because a product is "natural" does not mean it cannot harm you. If you intend to use CAM in your hepatitis C treat approach, gather information from someone who is trained and knowledgeable about CAM therapy. And always be sure to let all your health care practitioners know about each and every product, supplement, medication, and practice you are using.

The Future of Medicine - An Integrated Approach

Can, should, or must we explore combining CAM and western treatments? Would this provide potentially less expensive and more effective treatments with better quality of life, not only for people in the U.S., but for the rest of the world's population as well?

As we move forward in the 21st century, the general public, CAM practitioners, and western doctors are increasingly accepting the idea of integrative medicine. As CAM therapies and interventions are incorporated into western medical education and practice, the exclusionary term "complementary and alternative medicine" will hopefully be replaced with the more inclusive term "integrative medicine."

A number of respected health care institutions, medical schools, and teaching hospitals are setting up or have already set up integrated medicine clinics. Some doctors-in-training are being taught not only about western medical treatments, but also about the many herbs, supplements, and other forms of treatment their patients are using and/or requesting. Respected professionals from all medical disciplines are talking, listening, and working together as colleagues, much like the authors of this book. We hope that in the not too distant future, integrative medicine will be seen as providing novel insights and tools for whole-body health. Health care providers everywhere will practice this new form of medicine after learning the numerous traditions and disciplines that contribute to art of medicine and healing.

The Role of the Patient Advocacy Community

Patient advocates play a major role in many areas of medicine. HCV advocates have been largely responsible for the hepatitis C public awareness and education programs that currently exist. They work in communities and in prisons. They work with the many military veterans who have been infected with HCV through infected blood transfusions for war injuries. They work with police and firefighters, and with IV drug users. They speak before Congress and state legislatures, appear on television, and reach out to other media outlets. They have been responsible for setting up testing sites where people can be screened for HCV free of charge. They are encouraging states to develop their own testing plans to help prevent the continued spread of this disease. They are organizing the development of community-based HCV task forces.

Advocates are clearly a necessary and vital component in the fight against HCV. But HCV is a huge problem; many people are needed if we are going to continue to make strides for the good of all those living with HCV. We encourage you to get involved with one or more of your local HCV groups. Volunteer your time if you can. Just a few hours a week can make a big difference. If there is no HCV group in your area and you would like to start one, please give us a call (877-737-HEPC). We would be happy to give you information about how to establish an HCV advocacy group. If you do not have time to volunteer, you can still help by writing your state and local representatives. Tell them you want hepatitis C moved to the top of their agenda. Financial support is also needed; public awareness campaigns, offering free or low-cost testing, conducting educational programs, and all of the many other activities advocates perform daily require funding. If you can help the HCV advocacy community do its work through a financial contribution, we encourage you to pick up the phone and call today to make your donation.

Giving Hepatitis C a Face and a Voice

Each and every day, HCV advocates hear stories from the community of people living with hepatitis C about the negative stigma associated with the disease. Stigmatization and prejudice are often based on two factors: ignorance and impersonalization or "facelessness." While people may have heard of HCV, many have little knowledge about the disease, or worse yet, have incorrect notions about the disease. Ignorance often leads to fear, which is expressed as prejudice. For example, a commonly held misconception is that you can "catch" hepatitis C through casual, day-to-day contact with someone who has HCV. Of course, this is not true. But someone who holds this mistaken notion may develop a prejudice toward people with HCV as a result of his or her unwarranted fears. This is just one example of how lack of knowledge can contribute to stigmatization.

Impersonalization is also a factor in stigmatization and prejudice. It is often easy for us to hold onto judgmental thoughts about others when we think of them as a group, separate and distinct from ourselves. We often use phrases such as "those people" or "what they're like" when describing groups of people with whom we feel no sense of connection. Lacking a sense of connection, we are just a step away from forgetting the humanity we share with "those people." This type of "facelessness" can contribute to the stigmatization of people with hepatitis C. But such stigmatization often quickly fades when one realizes that "those people" are not separate, but are one's friends, neighbors, and loved ones.

Understandably, the stigmatization associated with hepatitis C has caused many people living with the disease to remain silent. However, we've all heard the old adage and have certainly experienced it's truth at some point: "The squeaky wheel gets the grease."

Becoming involved in the hepatitis C community by working with an HCV advocacy organization has many potential benefits:

You will be contributing to the process of raising public awareness and knowledge about hepatitis C.

Increased public awareness and knowledge will help contain the spread of HCV, and will decrease the stigmatization associated with ignorance and misconceptions about the disease.

Involvement with the community is likely to expand your own support system while at the same time providing help for others facing similar challenges.

Giving a "face" to hepatitis C will help others see that those living with HCV are people just like their friends, neighbors, and loved ones. This is often a powerful antidote to stigmatization and prejudice.

There is strength in numbers!

While in an ideal world, facts and need should speak for themselves, in the "real" world with many competing interests vying for a limited number of funding dollars, it is often those who are most vocal and who have the support of the largest numbers of people that are heard. As noted earlier in the chapter, the success of future HCV prevention, research, and treatment are dependent upon an infusion of governmental and private funds to support these efforts. We need to join our voices together so that decision makers can gain an understanding of the problems at hand. We must also let them know the hepatitis C community is strong, and we will not settle for insufficient resources to meet the needs of those who require our help.


You Are An Important Part Of The Hepatitis C Community, And We Need Your Help!


The National Hepatitis C Advocacy Council

The Caring Ambassadors Hepatitis C Program mission statement addresses the need to motivate the many HCV advocacy organizations to work together. In the summer of 2000, all the HCV advocacy groups were invited to participate in a meeting to determine if a collaborative approach would benefit people living with HCV. The meeting resulted in the formation of The National Hepatitis C Advocacy Council.

Since the Council was formed, we have grown to a 19-member, national organization with three additional organizations on our advisory panel. The Council is a forum for discussing common goals and strategizing about ways to become a formidable national force to advance the issues of importance to all people affected by hepatitis C. The Council has established ethical guidelines for all participating groups. The Council's guidelines promote a better quality of life for people living with hepatitis C, and stress that all member organizations must act responsibly and provide accurate, unbiased information.


The Council's Mission Statement

The National Hepatitis C Advocacy Council is an association of organizations that creates a unified voice, promotes ethical guidelines, and improves quality of services for people affected by hepatitis C.


The Council's Ethical Guidelines for Organizations

To place the needs of people living with hepatitis C and those affected by hepatitis C first.
Activities should be culturally and linguistically appropriate for the people served.
Responsibility to provide: Who you are, what you do, how you do it, funding sources
Responsibility to provide accurate and unbiased information.
Maintain a positive attitude and focus on educational aspects to help dispel fears and promote better quality of life for patients affected by hepatitis C.
All persons affected by hepatitis C should be treated with respect and dignity.

The Council will be working on a variety of issues in the future. A primary objective of the Council is to ensure that hepatitis public health policy is shaped to include funding for research and community-based organizations.

For more information on the Council, visit their Internet site at www.hepcnetwork.org. The Resource Directory lists the members of the council, as well as many other great educational resources.


Summary

Much has been learned about hepatitis C, but there is still much we have yet to discover. For the vast majority of people, infection with HCV is not fatal. In fact, most people with HCV will not die from the virus, but with the virus. Given enough time and financial support from the government and private sectors, researchers will undoubtedly answer many of the questions nagging scientists today. How does the virus infect? Has western medicine really been successful in clearing the virus, or is it hidden in a reservoir somewhere in the body? Why do some people clear the virus on their own, while others develop a chronic infection with devastating consequences? Why does one form of treatment work for some and not for others?

Even if all the scientific questions were answered tomorrow and effective treatments were available for everyone infected, there would still be hundreds of thousands of people worldwide who already have the disease, and hundreds of thousands more to whom it would be spread. Prevention is crucial if we want to achieve control of the spread of this disease. A critical need for information and education exists and will continue to exist for a very long time.

We, as individuals and as organizations, have the opportunity to play a pivotal role in putting the spotlight on this slowly progressive, insidious, and potentially devastating disease. It will take a concerted effort on the part of everyone involved - researchers, government agencies, the private sector, patient advocates, and the public at large - if we are to overcome this disease.
