have you seen my post, depsite 18month of Peg I still couldn't clear my HbSag. Now going for add on.
you have not posted for while. how is your blood tests one year into tnf after peg?
how exactly does HbsAg seroclearance occur in Intf mono therapy if no CD8 help?
i think the 7% who clears on intf mono had an active immune system response already before start of therapy, the annual rate of hbsag clearance on therapy naive hbeag neg is 4% and some studies even reported higher percentages
What I found interesting from the article though, is that theoretically it shouldn't take long on Nucs to rescue CD8 (months), but most of the studies done on add-ons are multiple years use of NAs then peg. We are in need of some studies with different time intervals on NAs, then add-on peg. Maybe the clinical data for GS-9620 will be able to shed some light on this, since they only required HBVDNA undetected for three months for the current trials.
Some Canadian study that I saw, had HbsAg clearance at 30% for people with Hbe-negative based on several weeks of treatment with NA, add peg, keep NA for a couple of more weeks than continue peg only. It was posted on the forum here somewhere. These patients were exhibiting very high Alt at the time of therapy. So it would seem to me that even if immune system is rescued during NA, it would still need a kickstart (so to speak) from Intf (or some immune modulator) to finally mobilize and clear. But at the same time Intf, inhibits CD8, how exactly does HbsAg seroclearance occur in Intf mono therapy if no CD8 help?
Another question would be for people with undetected (W/O therapy) HBVDNA, wouldn't they be the perfect candidate for therapy (vaccines, Intf, zadaxin) since their immune system should be fully recovered?
The good thing is that we are acquiring the knowledge of how the virus works at a fundamental level and what mechanisms it uses to evade the immune system. Is just a matter of time before we find the right combo to overwhelm it on a consistent basis for a high clearance rate.
thnaks this is extremely interesting article
it would be useful to gather also articles about effects of single nucs on immune system, i remember tdf, etv and telbivudine having different effects on immune system
it would be very interesting to see pretreatment of tenofovir plus telbivudine (since the strong effect of telbivudine on immune system) and then add on of pegintf with tenofovir only to avoid the sides experienced with telbivudine plus peg
Here is another paper on how add-on therapy is supposed to work. Very informative. Nucs rescue CD8 and interferon does the rest. Not sure if it has been posted here before.
no it is best to stop and restart it later on, she won t lose the effect of this 48weeks treatment if she restarts in 1-2years
There are studies saying that prolonged 96 weeks is safe and has response rate of almost 30% against 7% comparing to 48 week of interferon. I think if you can bear sides and high cost of pegasys just give yourself a chance and continue interferon.
i havent seen enough studies on this i prefer maitake only for now which is the most studied in vivo
@calebz..I'll again check with fibroscan in September.
@stef2011..Thanks for the link. I saw in other thread that you are taking Mitake muchroom supplement. Do you know about Lingzhi muchroom?
extremely interesting, especially the part of hbvdna intf alpha suppression, this is probably one of the reasons sequantial therapy works and pegintf mono doesnt
Throughout the tx I lost a lot of hair and had flu like symptoms and tiredness, wired headaches, sometimes more, sometimes less
dont worry the hair will come back 3-4 months after you stop, i also had all that by imiquimod and i think pegintf was a good try anyway you will benefit a little while on tdf mono anyway
the paracetamol taken while on peg is no problem if doses are low and correct for liver disease
your fibroscan is not much different, 6kpa is still healthy rage and that is probably just a little inflammation by the immune response made by peg, this will go down in few months too
lampertico is doing many studies and the add on study after longterm nucs is his too
peg+nuc immediately work well on hbe+ but much less on hbe-, the add on sequantial treatment is the way to go
April recheck that Fibroscan result.
Thank you all very much for your support . I am feeling a bit down at the moment. Throughout the tx I lost a lot of hair and had flu like symptoms and tiredness, wired headaches, sometimes more, sometimes less. I used paracetamol when I cannot stand it anymore but I tried not to use it often.
@celebz..I am very encouraged to know that "IFN will help despite the HBsAg result, there are studies that it lowers HCC risk a lot despite no SVR."
Sorry. I have to take back the last sentence about not needing any painkillers. I am not sure whether she took more medication than panadol for the side effects.
Everybody should have one try with interferon just in case they are lucky reponders. I remember Steff also said this before. I did not recommend April to do the combo. I also think she should do serial treatment. But just giving her support. It is kind of her to share her treatment experience. I do not think April needs any painkiller for her PEg.
You are wrong, there may be some nephrotoxic sides if you add painkillers people use to cope with IFN side effects. Remember not everybody handles IFN the easy way.. some have strong fevers/flu effect. It would be perfect of you link a study result to what you say about combo results. I think that most options on combo treatments here are based more on theory rather than actual med trials. Gilead is currently running a combo trial of IFN/TDF and results will be available around 2015. Its too bad they don't have a sequential arm just combo combinations. I think that what stef does has more sense than a combo: keeping TNF for a few years and then starting IFN.
You do realize that you'll still need to use Peg with Replicor right? Provided that the drug is ever approved in current state.
I agree combo treatment does not increase SVR but does not hurt.
Hi, what's your number in HBSag? Maybe IFN is good for preventing HCC because it's an immune booster. Boosting immune system naturally should have good result also but it's different for everyone. Always want to add new antioxidant to the regimen.
I feel for April.
I understand the add-on to nucs, but according to Lampertico presentation in January 2013, de novo therapy with nucs and peg does not increase SVR. As far as I can tell, he is one of the biggest proponents of using Peg initially on patients, and he does not recommend combo.
yaksss, I feel for you sorry..
Guys, you know we need to all go to Canada and sit in front or Replicor building, have them read all these stories...
That is what what we should do...
What's worrying is the Fibroscan result : you went from 4.1 to 6.1 within ~6 months of treatment that should help this result not worsen it from what Ive read.
You need to stay positive IFN will help despite the HBsAg result, there are studies that it lowers HCC risk a lot despite no SVR. I'm on IFN week 40 now and my HBsAg results behave similar to yours - it stays on same levels.
