Progress in HIV Research = Progress in Herpes Research

8 posts in this topic

Article explaining considerable progress currently being made in HIV research. I personally see progress like this encouraging for herpes cures. A successful solution to HIV could be manipulated and targeted to a weakness in herpes. Don't believe those that say HIV research is irrelevant to herpes. Because its not.

Thirty years after the AIDS epidemic surfaced, hope of conquering the deadly epidemic has never been greater, according to a longtime US leader in the AIDS fight, Anthony Fauci.

This hope has been spurred by recent advances toward a vaccine and new breakthoughs in treatment and prevention, said Fauci who has headed the National Institute for Allergy and Infectious Diseases since 1984.

"Over the last one and half years we have had several important advances which when you put them together and combine them are now pointing very strongly to the fact that we can essentially be able to ultimately control and obviously ultimately end the AIDS pandemic," he told AFP.

Previous discoveries include how male circumcision can reduce by almost 65 percent the risk of transmitting the human immunodeficiency virus, the effectiveness of vaginal microbicides and drug treatments that can prevent an infected pregnant mother from passing the disease to her child.

More recently, two clinical trials have shown just how effective antiretroviral drugs can be in preventing the spread of the incurable disease.

A study that ran from 2007-2009 and was published late last year showed that a combination of these drugs taken orally by uninfected gay men lowered their risk by 44 percent of becoming infected.

That rate rose above 70 percent when the pills were taken regularly, said Fauci who added he has "been in it now literally every day of my life for the last 30 years."

A clinical trial released this month involving mainly heterosexual couples in which one was infected and one was not showed a near elimination of the risk of transmission when the infected partner began an early regimen of antiretrovirals.

This trial is "extremely important because it proves the concept that when you seek out and treat them early rather than wait for their disease to advance, you have not only the well known beneficial effect of being good for the individual patient, but you have a very powerful secondary effect of preventing the transmission from the infected partner to their healthy sexual partner," said Fauci.

The NIAID and its researchers have been at the forefront of the fight against AIDS since the epidemic first surfaced in June 1981.

With regard to the hunt for a reliable vaccine, researchers have found some hope after 20 years of failure in a 2009 clinical trial carried out in Thailand.

"The vaccine trial in Thailand was only 31% effective, however that is at least a proof of concept that we can do better."

In 2010, teams of researchers identified two antibodies in a single individual which when combined in the lab blocked 90 percent of HIV strains known in the world.

Now that research is honing in on what specific part of the virus should be isolated for a vaccine.

"So if we are going to have a vaccine this year or next year or the year after, we don't know, but we are certainly making considerable progress."

In the meantime, a more comprehensive use of existing methods for prevention must be applied in the developing world in order to put the brakes on the epidemic, Fauci said.

"In the low and middle income countries, we only have about 30 to 40 percent of the people who really need therapy getting access to therapy," he said.

"The only way we can address this -- and this is the focus of what is going on over the past couple of years -- is prevention of HIV infection."

There are 2.7 million new infections each year, he added.

This gap will be difficult to bridge, warned Fauci, especially since the global economic turndown has slashed research budgets as a time when scientists need 10 to 15 bilion dollars more per year than the total 11 billion currently available for research.

"Unfortunately there is a very difficult constraint on resources throughout the world," he said.

I couldn't agree more. Although, I have been wondering if HSV is even more difficult to cure. A vaccine for HIV could also be very beneficial to people with GH. Even if it does nothing for ob's and shedding. If it were to bring the odds of contracting HIV back down, or eliminate it, that's enough for me. But then again, I would think such a vaccine would give us a nice immune boost.

Yeah, I saw this article about it and was glad to see that The International AIDS Society will this month formally add the aim of finding a cure to its HIV strategy of prevention, treatment and care. The cost of treating the disease is too much now and there is hope of curing it for the first time in a long time. I found it quite interesting that a gene mutation is responsible for the 1% of caucasions who are immuned to HIV. Now I am wondering if it's the same thing with people who are immuned to HSV. I haven't found any research showing that, but only research showing that there are people who are immuned. If scientist are able to use gene therapy to cure HIV, the same technique could possibly be used to cure HSV. But, that would be many years away.

Here is another point in the article from Science Daily that I really like:

Now scientists working on mimicking the effect of the Berlin patient's transplant have had some success. One experimental technique uses gene therapy to take out certain cells, make them resistant to HIV and then put them back into patients in the hope they will survive and spread.

At an HIV conference in Boston earlier this year, American researchers presented data on six patients who had large numbers of white blood cells known as CD4 cells removed, manipulated to knock out the existing CCR5 gene, and then replaced.

"It works like scissors and cuts a piece of genetic information out of the DNA, and then closes the gap," says Huetter. "Then every cell arising from this mother cell has this same mutation."

Early results showed the mutated cells managed to survive inside the bodies of the patients at low levels, remaining present for more than three months in five. "This was a proof of concept," says Lewin. Another potential avenue is a small group of patients known as "elite controllers", who despite being infected with HIV are able to keep it under control simply with their own immune systems. Researchers hope these patients could one day be the clue to developing a successful HIV/AIDS vaccine or functional cure.

Scientists are also exploring ways to "wake up" HIV cells and kill them. As discovered in the late 1990s, HIV has a way of getting deep into the immune system itself -- into what are known as resting memory T-cells -- and going to sleep there. Hidden away, it effectively avoids drugs and the body's own immune response.

"Once it goes to sleep in a cell it can stay there forever, which is really the main reason why we can't cure HIV with current drugs," says Lewin. Her team in Melbourne and another group in the United States are about to start the first human trials using a drug called SAHA or vorinostat, made by Merck and currently used in cancer treatment, which has shown promise in being able to wake up dormant HIV.

Hmmm, cutting out the CCR5 gene and replacing it with the gene that causes immunity. That's Meganucleases. Cellectis has proven that they already have an enzyme that can do this for HSV but instead of replacing a gene, it would cut out the HSV genes so that it cannot replicate. So, if they are able to safely cure people with HIV in this way, they will also be able to cure HSV with the same technique. Looks like this promising strategy just might get moved along a little faster than originally anticipated. Keeping my fingers crossed.

Towards the end of this video, Kate explains that only 3% of the funding for HIV from the NIH is for cure research. It's nice to see that it is increasing. But then again, I wonder if were having the same issue with HSV. Yet, if they do find the cure for HIV, that will free up a lot of funds and even boost the hope that a cure for HSV is possible. Remember, this video was posted in Nov of 2010. But recently a lot more money was granted for HIV cure research.

THIS IS AN INTERESTING REPORT THAT TALKS ABOUT TRYING TO GET CONGRESS TO SPEED UP THE PROGRESS IN AIDS RESEARCH, IT ALSO RELATES TO HIGH PREVALENCE OF AIDS/HIV IN HOMOSEXUAL MEN AS WELL AS THE HIGHER RISK IN HOMOSEXUAL MEN CONTRACTING HERPES VIRUS TYPE 8(WHICH I DON;T HEAR MUCH ABOUT), ITS AN INTERESTING READ TO SAY THE LEAST, IT SHEDS SOME LIGHT ON WHERE MOST OF THE NIH MONEY IS GOING TO:

      This is very unlikely to be genital herpes of either type. Many things can cause a blister like lesion such as yeast and staph. It is possible you have an oral HSV-1 infection (despite testing negative) and this would mean you do not have genital HSV-1 owing to the immunity. It is also possible that you have actually experience bacterial issues or similar that have appeared like cold sores.
    • WilsoInAus
      No need for any special practices. Simply best not to touch an active sore or let them touch another person. No need for too much special concern cleaning your face, but might give you confidence to use cotton balls to wipe your face apart from the cold sore. Owing to your immune system you have virtually no chance of being infected elsewhere on your body.

      The 75mg daily dose of the original pritelivir led to an 87% reduction in the relative risk of viral shedding, which would likely curb the spread of HSV, especially if combined with Acyclovir. The reason they put the program on hold was because they gave monkeys 70 TIMES this daily dosage and the monkeys had skin problems. But who is going to take 70 times the normal amount? If they are now continuing with pritelivir development, they should at least mention that the "snag" was reconciled. Why keep everybody in the dark?  If not interrupted, we could have used Pritelivir for a few years, then switched to a more advanced therapeutic vaccine or drug in a few more years. Maybe this story will have a happy ending after all.

      It's great to see other people with positive attitudes and im very similar in that i learned years ago to be grateful for what i have because there are worth of people in the world and me and when i was diagnosed the year ago i pretty much accepted it because of those thoughts.  Of course my biggest fear was that no one would want me but that's proven to be completely untrue but I've also found that being fortunate enough to have no outbreaks has made a real difference as well. Unfortunately there are some people who have constant symptoms and really struggle with this mentally and it's a shame because as you said herpes really doesn't change your life but your mindset does if you let it
    • Lisajd
      It could be either.  Generally symptoms are tingling and itching.  Friction can cause an outbreak though.   If you are in your first year you will shed more but it also depends on how often you have outbreaks as to how much you shed as well and if you are on anti virals you shed less   It's funny it reminds me of a time when I had sex with my boyfriend and I felt this really hot burning sensation but it was because he was eating chili during the day and must have got under his finger nails.  
    • Lisajd
      It's actually interesting the whole lysine vs arginine thing because even Terri Warren said there is no valid evidence that a diet high in lysine and low in arginine makes a difference.  She said  it's more about some things trigger outbreaks more than they do others in different people.  I also read that lysine is not very effective with HSV 2.  @Shocked&Confused it really is a trial and error situation I know for me that eating nuts on a daily basis have not been a problem I think a lot of things are in moderation as well but I would suggest just keeping normal diet and if you have an outbreak assess what you had it in prayer and you will know what your triggers are at least while you're developing antibodies in the first year it might be a different story with your diet.    
    • Lisajd
      Also if you are on antivirals lysine isn't going to make any difference and even with HSV 2 the jury is out on whether it's effective anyway so you might be wasting your money on that one.  Definitely the stress is going to be a contributor so perhaps you can find some natural supplements to help you manage that better.  Is there anything else going on in your life as in hormonal changes are you getting your periods all the time as well
    • Hester
      Are the outbreaks finally getting under control?  Hope you're doing better.

      I made the mistake of buying a pack of peanut butter cookies from the grocery store bakery and eating almost the whole thing in one herpes-induced depression cry-fest Wednesday night and by Friday...BOOM!  No more peanut butter for me
    • Hester
      I found your blog.   I saw that you changed to About Time protein powder. You like banana the best?  I'm thinking I'll try the vanilla but I'm worried the flavor might not be good.....
