Viral load and disease severity have never been related to each other in studies. Comparing viral load and biopsy reports show repeatedly that those with a high viral load show no more liver damage than those with a low viral load (or no viral load at all?) and vice versa. Viral load does not account for the amount of liver damage. Yet, we measure treatment by viral load. Why?
Because we have tried without success to find a measure for treatment success and cannot find one. We tried normalized enzyme levels (without success) and we are now using viral load because it is perceived to be cheaper than another biopsy. We have never had a study looking at lifestyle changes alone compared with treatment and measured liver disease progress/regression/stasis.
We have no proof one is any better than the other, though we are pretty certain lifestyle changes can improve the lot of any patient without undue risk or making things worse. For those in aposition to wait and see, this is becoming amuch more attractive option for many clinicians. The benefits of treatment are far from proven.
So, you drop viral load after this gruelling (for most people) and potenially toxic treatment. We still don't know if this has any real significance. We hope it does, but we really do not know it for certain. Is your liver disease better? We do not yet know. So far, it is an assumption yet to be proven. So, are people with sustained viral responses motoring on with their lives with a false sense of security?
We also do not know whether this "response" is a suppression of virus in other parts of the body, like the organs and the brain and central nervous system. Early evidence suggests that it may not be. But studies outside liver disease, or looking at early chronic disease have NOT been done.
So, science marches on. The basic premise of viral suppression having true significance is still being questioned. It had some merit in HIV, so that idea has been translated to HCV. But, is it a reliable measure or just one we use because we haven't found something better?
For some patients, the potential benefits are worth the risks presented by the treatments, but most have complicating factors that need careful assessment.
Patients need to know much remains controversial (not really, the experts know a lot of this stuff) because it is being presented as being a "given." It isn't a "given."Most people who die of hepatitis C die because they were diagnosed so late in the disease, neither lifestyle changes nor treatment is an option and transplant is necessary. Most people dying of hepatitis C are dying waiting for scarce livers, so diagnosis (testing)and increased liver donations would have a higher impact on the death rates than interferon treatment. The people at highest risk, and highest risk to others, are those who do not know they are infected and therfore do not know to make the requisite changes to lifestyle and to take precautions against both progression of liver disease and transmission to others.This information is not gleaned from HCV chat rooms and message boards. They are great for support, but often very short on hard information. I chose to post on this board because it seems to have the potential to be the exception to the rule.
This information is available to anyone willing to find it. I admit that it is hard to sort grain from chaff, but the effort is well worth it. Marketing and science, science and marketing: it is so often hard to distinquish the two.
Add those arrows to your quiver when decisions are being made and opinions are flying around.

HMMM lets see, seven million liver destroying, brain numbing, exaushting, achy, painful Bugs in my body
- or none.
Yup thats a hard choice.
Someday we will make this right,
One day we will win this fight.
Do not let treatment control you,
Control your treatment.
Be positive, to achieve a negative, be well all.
There is no test that can measure every area of your body and determine whether there is virus anywhere.
What we have is a test that measures a reading of "undetectable." This means that the number of virons on the day of the test are not detectable IN THE BLOODSTREAM with the currently available technology. That is all it can do at present. Viral load does go up and down all the time.
I serve on an two advisory boards with scientists at the highest levels of expertise in laboratory medicine (and pathology). I am not an expert on laboratory medicine, but I can report that virus can sometimes be found elsewhere in the body when it is undetectable in the bloodstream, that the tests are not yet perfected, and that this is information that is largely ignored in markleting messages.
Your body and your choice, just know what you are choosing and what is not yet possible to know. Speaking of which, the symptoms yoou list are likely to be caused by neurological manifestations of the HCV virus (my specialty) We have no evidence at present that treatment addresses the neuological manifestations, but we have good data to suggest that interferon can cause those problems. Also true for anti-depressants and some of the other treatments used to mitigate the interferon therapy.
For many people, the choice is just not a simple one and they want to have the most accurate information available in order to make a decision. Simplistic concepts and marketing logos aren't enough.
happy huntin'

Howdy-
When asked "why did you start treatment"
here was one response-
"At least we know what to expect on this treatment. What we don't know is how the Hep C will affect us later on in life when we should be enjoying everything we hoped for. I was diagnosed in around 1991, and had no symptoms for years.
Then it started.
I developed what is called Porpheria Cutanea Tarda, or PCT, which is a blood disorder that causes blisters to any part of the skin that is exposed to the sun. What a nightmare for a person who is into running, cycling, tennis, gardening, and just generally enjoying the outdoors.
My wife and I had just bought a house in the country and we moved there as part of our plans to live out our lives there. It turns out that I also had Hemo-chromatosis, which means that your iron level in the blood goes sky high if not treated.
Iron levels should be at about 70 to 100, and I was at over 700. Both these conditions were directly related to my liver not functioning properly. Of course, all of this was caused by that little virus called Hep C.
The liver has many functions besides filtering the blood, and the possibilities of diseases that you can be attained with are unlimited. This is the reality of living with Hep C.
You do not know when, where or how it will hit you. As was said so well, it is like living under a dark cloud.
Why do this treatment? Cause I want to have the control of my life back!!!! "
One of many responses to that Question,
many even more devestating and heartfelt than this example, but may bring some people down.
Does it not make sence, to live happily ever after, avoiding alcohol, smoking, eating right, with ZERO ammonts of the HCV BUGS in your system AFTER treatment,
then trying to live happily ever after, with millions of the Dragon bugs in your system waiting for your immune system to weaken, and catch ever other virus out there.
People who do not have a medical PHD should not be telling people they can live happily ever after with HCV, or wait until a better treatment comes along, its like telling someone with terminal cancer,
Well since kemo thearopy is so toxic, and not yet perfected, wait until a new user freindly treatment comes along, [a little over dramatic sceneo, but makes my point ?].
I am not defending Present treatments,nor trying to presude any one to even start a Treatment, that is a decision that should be left up to them personally, [after much research], and consulting a licensed Medical PHD.
"Does it not make sence (sic), to live happily ever after, avoiding alcohol, smoking, eating right, with ZERO ammonts(sic) of the HCV BUGS in your system AFTER treatment,
then (sic) trying to live happily ever after, with millions of the Dragon bugs in your system waiting for your immune system to weaken, and catch ever other virus out there."
NO, it doesn't make sense unless it is proven that it actually makes any difference in morbidity and mortality. It addititonally doesn't make sense if you end up with worse problems than you started with. It does make sense to live this way to avoid progression of liver disease in the absence of treatment and it is a valid choice (and for some, it is their only option)that should be respected. Living this way is a good idea for everyone with hepatitis C whether they treat or not; respond to treatment, or not.
The benefit of the treatment should be greater than the risk of living with long term problems that make you feel worse or increase the damage to your liver. You should have, at least, the assurance that you have improved something, not just the hope that you have, maybe, improved.
I am not saying there is no benefit to the treatments for anyone. I am saying that the risk/benefit must be in favor of the patient and enough information about your own medical history weighed against what the realistic expectations of the current treatments are. It may be that the risk/benefit ratio is in your favor, but we haven't done enough research yet to know whether the same result can be obtained through changes in lifestyle choices. Emerging scientific work suggests that you may realize as much benefit from changes in lifestyle as from the treatment with an early diagnosis or in the absence of progression. This is simply something to consider when making a decision.
There is absolutely NO evidence that a person living with hepatitis C is more susceptible to bacterial infections or their sequellae than anyone without HCV. There is no evidence that your immune system will weaken over time due to HCV or that it is improved after a course of interferon therapy that will help resist infections of any kind.
Those messages are the very ones that scare people into thinking (wrongly) that the HCV virus is deadly to anyone who has it and which causes unnecessary treatment in those who do not, and probably never would, need to be treated and for whom the risks far outweigh any potential benefit. There are diseases that make a person more susceptible to hepatitis C, however. Co-infections and co-morbid conditions can make a huge difference in the outcome one can expect with the treatments, too. But, usually, these preclude treatment, can be made worse or are brought forward by treatment itself.
Can you image being someone diagnosed and told that they cannot be treated due to a contra-indication or co-morbid condition and reading the message that you will surely die or become really sick without treatment? It is simply untrue for the large majority of those with hepatitis c.
I get telephone calls every day from people referred to me from the CDC hotline who think they are going to die because they are 1) inappropriate for interferon treatment or, 2) cannot afford to be treated and are panicked after hearing they will die if they don't get treated. I hear from desperate people pleading for financial assistance to stay alive.
This very morning I spoke to a single mother who was told (by a medical doctor!)that, at stage 3 biopsy, she had only five years to live without treatment. She cannot afford to treat, quit work or bring herself to give up her children for adoption so they will not be too attached to her when she dies. She called absolutely frantic. Meanwhile he said nothing to her about her smoking or alcohol intake.
Shared personal stories are all useful, but in the absence of a complete medical history and thorough assessment, we only have the assumptions of a person "somewhere out there" in cyberland that what they are experiencing is attributable to hepatitis C and not another problem that has not been diagnosed because it wasn't looked into. We also cannot know what was said in the privacy of the medical office that might have been misunderstood.
Good information is available to anyone and you do not have to be a PhD to get it or understand it. In fact, I hear from lots of Phd's asking for information and lots of patients whose doctors who know virtually nothing or just enough to be giving very bad advice to people.
I tell everyone exactly what I am telling everyone here - process the information critically and do research on your own.
You are the one who will gain the benefit or suffer the consequences.
