here is a good website with lots of info concerning viral loads etc.
I had some questions for the nurse ...on this site.
look under bandman postings.
She is real good about answering questions.

Did you get this test in Argentina? It means that they used a test that doesn't measure a viral load any higher than that and mine meets or exceeds the upper limit. If your PCR reads >850,000 IU/ml as Jim suspects, then your lab used a test that only measures up to that 850,000 upper limit.
My original PCR came back as >1.3 mil IU/ml. What I learned for myself is that, in Canada, the 1.3 mil IU/ml is the highest limit any labs in Canada test to. (That's supposed to be changing soon.) I was in the middle of searching for getting my own PCR including going to the U.S. when I landed in a drug trial and then got an accurate PCR as it was done in the U.S. and turns out my viral load was 2.1 mil IU/ml.
Having said that ... viral load doesn't directly co-relate with liver damage. Where viral load comes into play is that it's been shown that you have better response outcomes with treatment if you start with a lower viral load. Some people delay treatment for a time to bring their viral load down first, depending how high it is.
It's important to have an accurate baseline prior to starting treatment. If / when you get to that place, you'll want an accurate baseline for that, therefore a test that measures at a broad range as Jim has mentioned. Or maybe you want to know that now. Up to you and your "need to know" factor.
While studies use a cut-off of 600,000 as the difference between high and low, outside of a study context, 850,000 IU/ml is actually moderate. However, if your test IS >850,000 IU/ml, all you really know is that you're higher than that but not by how much.
Hope that helps.
Trish
What is supposed to happen is once the upper limit is reached the sample is supposed to be diluted and tested again to give a more accurate VL. This second step wasnt done probably to save a few$. I had the same thing occur to me last Tx.
Newer PCR test have a mind blowing dynamic ranges and can detect up to 69-100 million depending on the test.
HVL is HVL so in a way it doesnt matter what your true VL is.
Well it does as it makes it a little difficult to work out whether you have a 2 log drop but other than that it doesnt matter.
CS
I agree with you .. VL doesn't matter UNTIL you are preparing for treatment and then you want an accurate baseline so you know whether you've truly had that 2 log drop and that is exactly why I wanted the accurate test. I was getting ready to start treatment and I wanted the accurate baseline so I'd know if I really had a two log drop or no.
On personal speculation .. I do wonder if VL matters in other ways. While the impact on the liver may not directly co-relate with VL, there are a number of other health issues that seem to be an offshoot of having HCV and I wonder how much VL plays a part in those.
So do I. I have a feeling that the higher the VL the more symptoms.
Until recently Australia only had tests that went up to 800K. Sux doesnt it.
Now when I get to use a test that goes up to 69,000,000 (COBAS Taqman) it comes back at 600K.
So I now wonder what my pre Tx VL actually was, but hey not much i can do about it now.
CS.

----------------------------------------------------------------------
I'm sorry, I'm not following. Your viral load currently sits at 600K?
This test, this COBAS Taqman, this is now available in Australia?
Thanks, CS.
Trish
Before my last Tx my VL was >800,000. No Idea how much greater.
The VL test I had done Last month came back at 622,000.
Now I had been taking HR supps for a month so not sure how much influence they had.
Yeh Aust now has the Roche COBAS Taqman assay. Range 43-69,000,000IU.
Guess the other one was COBAS Amplicor but not sure. Anyway its range is somewhat larger.
I certainly feel better than before my last Tx, no more fatigue and insomnia so something is different and VL is maybe one of them.
CS
Actually, that is an excellent point. Same sort of thing I see people post-tx posting all the time. Interesting. Thanks for the perspective.
Trish
Actually.. I got that without blinking. 600K is naturally to me 600,000. Just wasn't sure if you were meaning that your viral load is inaccurate because of the test or just what you meant.
Incidentally... isn't K 1064? ;->
(I know...I know )
Nah K=1024. I was going to mention that. Then thought it will just confuse things.
Actually it can mean both 1000 & 1024.
I didnt care at the time that my my VL only came back >800K.
Wish i knew its true figure now.
CS
As for your VL .. I'm sorry it went that way for you. We can't turn back the clock .. there's only moving ahead. You did the best you could with what you knew and you'll do the same going forward. It's all we can do, yes?
Take care.
Trish
There are 256 possible combinations with 8 bits.
1 bit = on or off
8 bits = 1 byte
4 bytes = 1 word
1 word = 1024 (256 x 4)
Computer lession over
Yeh hindsight is a wonderful thing aint it.
CS
I agree that the lab that did my viral load test probably could have diluted the sample and run it again, and they didn´t do that because of the added expense. My hospital is run by accountants, there´s no doubt about that :[
Re viral load ranges, I saw somewhere on a website that 0 - 1 million is considered low, 1 million to five million is medium, amd above 5 million is high. Does that make sense to anyone?
Here´s a full transcription of my lab result - in Spanish, naturally - for what it´s worth:
===============================================
CUANTIFICACION DEL VIRUS DE LA HEPATITIS C
(Carga Viral HCV, Amplicor)
Metodo: Cuantificacion por el metodo "HCV Monitor - Roche",
a traves de la aplificacion de un segmento de 244bp de la region 5 No Codificante. Primers externos - KY80/KY78 biotinilados.
RESULTADO:
CONCENTRACION: Mayor de 850,000 UI/mL
Limite de deteccion: mayor o igual a 600 UI/mL.
Rango de linealidad: 600 a 850,000 UI/mL.
============================================
Can´t tell if it´s Monitor, Roche, Amplicor or what.
I´m pretty frustrated about this result because I asked right off, when I was first diagnosed HCV+, for a cuantitative test and they did just the Yes/No PCR. Sorta tricked me (so as not to say "lied to me"). Now I wait another month and I get this "more than..." routine. So I am not a happy camper at the moment.
Sure, maybe viral load doesn´t correlate with progression of fibrosis/cirrhosis, but I believe in my case it will mean the difference between antiviral therapy or not. At 64, with HCV 1b, if my viral load is very high I don´t have much of a chance. OTOH, if it´s really just 850k, maybe it´s worth trying.
Anyway, thanks again to all of you for your help. This forum is a life saver. You are the best.
Mike
http://****.com
but from the report it looks like they used Roche's amplicor monitor, probably the most commonly used test world-wide until the emphasis on more sensitive tests.
As far as tx planning goes, the low/high vl cutoff as a predictor of success has moved down to about 400,00 in recent studies. Not knowing how much you're over 850,000 may be annoying but it's not information that would guide any decision. If you do start tx, you'll want a baseline test with a higher range so you can measure VL decline in the early stages - an important predictor.
} down to about 400,00 in recent studies.
What does that mean, exactly? Since I´ve got more than 400,000, in my case a lot more apparently, my chances are real bad?
Isn´t viral laod used as part of the info to guide the decision on tx?
What baseline tests can you suggest when starting tx?
Thanks. I´m new to all this and there's a lot to learn.
Mike
But in the end it will be your decision

Quantification of hepatits C virus
( HCV Viral Load, Amplicor)
Method: Quantification using the "HCV Monitor-Roche" method through the amplification of a 244 bp (base pairs) segment of the non-coding region number 5. External primers- KY80/KY78
RESULT
Concentration: More than 850 000 IU/ml (international units/ml)
Detection threshold: more or equal to 600 IU/ml
Lianeality range: 600 to 850 000 IU/ml
Basically this means that your viral load through RNA amplification is more than 850000 which means it is very high, higher than what the method can quantify. Just bear in mind that viral load is not a very important predictor of response to treatment.
..... my wife translated; she is from argentina and a physician; you can go for the better tests to any better hospital in buenos aires; she worked at sanatorio otamendi, it's privat and very fancy; you'll get good tests there but she doesn't know what they cost; it's more for the upper class; you can try though, it's right across the street from las clinicas, and the univ. of buenos aires school of medicine; intersection acuenaga/cordoba if you go by cab; ciao good luck

No. It has been by some doctors but it shouldn't be. My first doctor used viral load as his ONLY guide to suggest tx for me and that is an inaccurate foundation upon which to base treatment. I didn't know any better at the time, this was all new to me and my first doc had me reeling out of his office with numbers like >1.3mil IU/ml and that I needed treatment .. and I thought I was done for too. Only I found out I wasn't. So perhaps you're feeling like I did when I got my first PCR results.
My reason for going for a second opinion was BECAUSE he wanted me to treat based on viral load alone and that told me he didn't know as much as I would have liked from my treating doctor. When I explained to my next doctor at the university hospital I now get treated out of that my first doc wanted me to treat without a biopsy based on viral load, his eyebrows immediately went up and so did those of the other doctor in the room and they just looked at each other without saying anything. And we moved on. So those docs weren't basing any treatment on viral load. In fact .. they based treatment more on how ready I was myself for treatment. They quizzed me on that and they were willing to go ahead as a result.
You are not "done for" if you have a high viral load. Viral load is NOT an indicator of liver damage. I think alot of us could post what our viral loads are compared to what our biopsy results turned out to be and that would tell a great deal. My doc was very concerned about my viral load and I turned out to be only Stage 1 Grade 1 liver damage. Interesting, eh?
To have an accurate baseline is important when you DO decide to treat. How well you're responding is based on how much your viral load is dropping .. and if you don't know where you started, how do you know if you dropped 1 log or 2 logs or by how much. It puts a big question mark on everything. So, to me, an accurate baseline is very important.
I could dig up studies because I know that adds validity as it does to me too .. but I'm a bit tired and I just wanted to add in personal experience and knowledge gained along the way for now.
I hope this helps, Mike. Hang in there.
Trish
Otherwise, the viral load just remains a number to measure treatment responses to...

"Prediction of treatment outcome in patients with chronic hepatitis C: significance of baseline parameters and viral dynamics during therapy."
http://www.ncbi.nlm.nih.gov/pubmed/12601358
and
"Managing chronic hepatitis C in the difficult-to-treat patient."
http://www.ncbi.nlm.nih.gov/pubmed/18036096
pubmed ids 12601358 and 18036096 in case the moronic mh link-censoring filter strikes. Full text for the latter, which includes a description of other prognostic factors such as age, race and fibrosis is available on the medscape site (you have to register).
While it's true that a low viral load (that definition varies study to study) produces somewhat better SVR results, most people who have HCV (and therefore most people who treat) do not have low pre-tx viral loads. The other point is that high pre-tx viral loads deliver about the same SVR results as very high pre-tx viral loads. In other words, if you have 3 million or 30 million pre-tx viral load, your chances of SVR are about the same. Most important point is that viral load does not correlate with liver damage.
So in wrapping it all up -- I would make the tx decision based pretty much on liver damage as determined by your upcoming biopsy. If you have significant liver damage, then you have to deal with it one way or another regardless of viral load. If you don't have significant liver damage then you have time to wait, again regardless of viral load.
As far as the tests used, it would be more helpful to get a pre-tx viral load test -- esp a baseline test right before tx -- that can measure viral load much higher than the test you used. That way you could track initial viral response better if you so choose. Once treatment starts, it's important to use a test that goes below 600 IU/ml. Ideally you want to go down to 5 or 10 IU/ml. The more sensitive tests will correlate better with study data determining RVR, EVR, etc.
All the best,

If you have links to this information, I'd be very interested in reading this, thanks.
Trish
===================
This sounds like a reasonable explanation of why those with pre-tx viral loads seem to have better SVR results. In fact, I've speculated that one could in theory try and time treatment with periods of low pre-tx viral load (i.e. better immune activity). That said, like Trish, I'd be interested in any supporting study data.
"...when the immune system recovers, it fights the hep c back into a corner...so, if the immune system remains weak, the hep c's damage accelerates... "
-------------------------------
Vrial load can fluctuate wildly, so not sure how helpful this is, assuming it's true. Also interested in any supporting study data.
Here's what I have so far - S/B UND now just waiting on the results from last weeks PCR although it was the day before Enbrel - so we'll see.
Date VL
Jan 25-08 - 41,540 after Enbrel
Feb 6-08 - 3,730,000 before Enbrel
Feb 26-08 - 677,000 after Enbrel
Mar 27-08 - 2,240,000 before Enbrel Started tx April 5th
April 17-08 - 203 after Enbrel
April 29th - probably UND - waiting results - but day before Enbrel
Question for you - The Tagman that they use at UCI only goes to the low end (200)
Should I be concerned with getting one more sensitive with the numbers I have so far?
I am considering stpping Riba at 4 months per another trial that showed no dif in 2B's to stay on peg 6 mo and rib 4 mo.
Thanks,
Mikki
My doc said it was high but had seen much much higher... Can any one suggest what I really should be doing BEFORE TX...eating not eating, taking that will boost my immune sysyem "safely". I used to take immune boosting suplements like Astragulus... but I am so afarid to take anything now that might mess up the treatment. All my doctor said was " start training like you are going to be in the olympics!" So should I be eating a lot of carbs then!!!!????
This high VL thing really has me frightened now. :(
Thanks for any info you can give.

Enbrel Side Effects
Enbrel side effects have included reports of infection leading to death in some instances. Entering the U.S. market in 1998, Enbrel patients suffered Enbrel side effects so serious that it led the company to change Enbrel side effects labeling. In addition, Enbrel manufacturer sent a Dear Doctor letter to physicians warning of the serious and deadly Enbrel side effects that could occur.
Symptoms of Enbrel side effects that may signal infection is present are fever, bruising, bleeding, or paleness. If these Enbrel side effects are experienced, the patient should consult a physician immediately. It is more common for patients with a higher susceptibility to infection to experience Enbrel side effects. Other Enbrel side effects involve serious nervous system disorders like multiple sclerosis, seizures, and inflammation of the nerves of the eyes.
If you have suffered from Enbrel side effects and would like to learn your legal rights and options, please contact us.

I think your past this point - but anyway there is statistics that prove there is a much better SVR rate if you go with a Hepatologist.
Take Care,

The idea about serial dilutions using a low-range test like the Roche Amplicor Montior is excellent. I've emailed my GP at the hospital with the request to re-do the PCR, this time with dilutions. I mean, what the heck, they've done two PCRs on me, told me both times they were quantitative, and I still don't know my viral load which personally I find it very hard to believe doesn't matter. How can it not matter how many millions of virus are in your blood, if only because they are occupying the immune system when it should be doing other things? Also, because it looks like part of what damages the liver is the immune response to the infected hepatocytes. Ain't nobody gonna tell yours truly that the number of infected hepatocytes don't matter, cause that's jes plumb loco,
Anyway, I haven´t read all the posts to this thread yet, didn't have time because I was starving myself and doing laxatives all weekend in prep for the colonoscopy/endoscopy this morning (perfect results: no esophageal varices, and the colon problem due to diverticulitis and not apparently liver-involved), so I'll probably post again here later.
Cheers to all!
Mike
But please tell your wife this: A lab in Rosario named CIBIC S.A., which administers Fibrotest in Argentina for the French inventers of the test, is refusing it to me because my hospital in Buenos Aires doesn´t have it on their list of approved procedures, My hospital doesnt approve any procedures that cant be done by my hospital, because of the costs. And Cibic won't take the order from another doctor, apparently for fear of my hospital.
So if I go to sanatorio Otamendi, what do I have to do, lie about being a patient at the Italian Hospital? Please ask your wife.
That's what it's like here in Argentina, see? Everyone's afraid of everyone else. Like it was a police state.

Re - the hcv kinetics, I know it's counterintuitive. A standard post here is from someone who has just found out their VL is in the millions and now wants a referral for a good funeral home. You may want to look at
http://www.ncbi.nlm.nih.gov/pubmed/9756471
the original hcv kinetics paper, or some of the many follow ons.
Here's one at medscape with full access
http://www.medscape.com/viewarticle/543530_1
Probably the single most striking point is "the daily production rate of the virus was estimated to be 10**12 virions" (from the above review) - ie the virus is so remarkably prolific that any measurement is basically only an indicator of the effectiveness of suppression.
I finally got the referral to the hep, so I'm happy, but waiting. Really want to get the biopsy done, but again.... waiting.
All the best for now, Marcia
ciao
I had some better news today: Fist, I went back over to the university teaching hospital this morning, collared the chief hepatologist at the outpatient clinic, and got into a heated discussion with him about biopsy vs. other tests. After showing him the pics on FibroTC he gave me the order for the tomography. Then I got an email from the radiology secretary at my hospital (a very sweet person who has been at bat for me) to the effect that she talked them into doing the tomography for me if I pay for it. Only thing she left out was the cost . So, if I can get the folks in Sevilla to get moving, it looks like I might get my FibroTC after all.
Now, now....don't get all p****d off at me, I'm gonna do the biopsy, too, just as soon as my hepatologist wakes up.
