Scientists on brink of HIV cure within months

hiv cellDanish scientists are expecting results that will show that “finding a mass-distributable and affordable cure to HIV is possible”.

They are conducting clinical trials to test a “novel strategy” in which the HIV virus is stripped from human DNA and destroyed permanently by the immune system.

The move would represent a dramatic step forward in the attempt to find a cure for the virus, which causes Aids.

The scientists are currently conducting human trials on their treatment, in the hope of proving that it is effective. It has already been found to work in laboratory tests.

The technique involves releasing the HIV virus from “reservoirs” it forms in DNA cells, bringing it to the surface of the cells. Once it comes to the surface, the body’s natural immune system can kill the virus through being boosted by a “vaccine”.

In vitro studies — those that use human cells in a laboratory — of the new technique proved so successful that in January, the Danish Research Council awarded the team 12 million Danish kroner (£1.5 million) to pursue their findings in clinical trials with human subjects.

These are now under way, and according to Dr Søgaard, the early signs are “promising”.

Dr Ole Søgaard, a senior researcher at the Aarhus University Hospital in Denmark who is part of the research team, said: “I am almost certain that we will be successful in releasing the reservoirs of HIV.

“The challenge will be getting the patients’ immune system to recognise the virus and destroy it. This depends on the strength and sensitivity of individual immune systems.”

Fifteen patients are currently taking part in the trials, and if they are found to have successfully been cured of HIV, the “cure” will be tested on a wider scale.

Dr Søgaard stressed that a cure is not the same as a preventative vaccine, and that raising awareness of unsafe behaviour, including unprotected sex and sharing needles, remains of paramount importance in combating HIV.

With modern HIV treatment, a patient can live an almost normal life, even into old age, with limited side effects.

However, if medication is stopped, HIV reservoirs become active and start to produce more of the virus, meaning that symptoms can reappear within two weeks.

Finding a cure would free a patient from the need to take continuous HIV medication, and save health services billions of pounds.

The technique is being researched in Britain, but studies have not yet moved on to the clinical trial stage. Five universities — Oxford, Cambridge, Imperial College, London, University College, London and King’s College, London — have jointly formed the Collaborative HIV Eradication of Reservoirs UK Biomedical Research Centre group (CHERUB), which is dedicated to finding an HIV cure.

They have applied to the Medical Research Council for funding to conduct clinical trials, which will seek to combine techniques to release the reservoirs of HIV with immunotherapy to destroy the virus.

In addition, they are focusing on patients that have only recently been infected, as they believe this will improve chances of a cure. The group hopes to receive a funding decision in May.

“When the first patient is cured in this way it will be a spectacular moment,” says Dr John Frater, a clinical research fellow at the Nuffield School of Medicine, Oxford University, and a member of the CHERUB group.

“It will prove that we are heading in the right direction and demonstrate that a cure is possible. But I think it will be five years before we see a cure that can be offered on a large scale.”

The Danish team’s research is among the most advanced and fast moving in the world, as that they have streamlined the process of putting the latest basic science discoveries into clinical testing.

This means that researchers can progress more quickly to clinical trials, accelerating the process and reaching reliable results sooner than many others.

The technique uses drugs called HDAC Inhibitors, which are more commonly used in treating cancer, to drive out the HIV from a patient’s DNA. The Danish researchers are using a particularly powerful type of HDAC inhibitor called Panobinostat.

Five years ago, the general consensus was that HIV could not be cured. But then Timothy Ray Brown, an HIV sufferer — who has become known in the field as the Berlin Patient — developed leukaemia.

He had a bone marrow transplant from a donor with a rare genetic mutation that made his cells resistant to HIV. As a result, in 2007 Mr Brown became the first man to ever be fully cured of the disease.

Replicating this procedure on a mass scale is impossible. Nevertheless, the Brown case caused a sea change in research, with scientists focusing on finding a cure as well as suppressing the symptoms.

Two principal approaches are currently being pursued. The first, gene therapy, aims to make a patient’s immune system resistant to HIV. This is complex and expensive, and not easily transferrable to diverse gene pools around the world.

The second approach is the one being pursued by Dr Søgaard and his colleagues in Denmark, the CHERUB group in Britain, and by other laboratories in the United States and Europe.

    Glory Be To The Lord Almighty join me to thank this man worthy to be called my great and powerful father called Dr Zuma zuk. Last time i met a comment online against the great and powerful work Dr Zuma zuk has done with her HIV/AIDS ailment.
    Firstly: i will thank Mrs Bernille for letting the world knows the powerful man that help her from AIDS disease. This was what i have all my life been waiting for since i was infected by HIV last 6 months. I always spend money for drugs always but still yet my weight becomes poorer and my joint always getting painful and inching all day. But when i met this comment last 3 days, i quickly contacted Dr Zuma zuk the Traditional helper. He is from the western part of Africa, i didn’t spend much as i spent for drugs each day, and i for the fact truly reason this because my life was already as take by this disease called AIDS. Truly, when it was 9 o’clock on Monday this week he called me that his oracle urgently required some few life items to enable the disease wipe out successfully, then i was asked to send down 200usd ($). Which i did. He truly bought the items and surprisingly, yesterday afternoon Dr Zuma zuk called me that my work has been finally done and it work out well. I was glad and he told me to rush down to my hospital for checkup. Which i really did, my brothers and sisters i went down crying because no one has ever done this to a person in life. Dr Zuma zuk truly healed me. I was crying it was a dream to my eyes when the doctor said to me that I am HIV NEGATIVE. I am now a free born in life, am now like other people who now think things like human. For these days and forever, i will accept Dr Zuma zuk as my father and my healer and helper. He is a great man. Thank you sir. I know i cant reward you. But my God in heaven can. Thank you sir once again.
    Regards.

    I was a HIV-AIDS patient and I got it from cheating on my husband. It was sort of a payback but a week later I was told by a friend that the person who I cheated with had the HIV-AIDS virus and did not tell me. I was so stupid by not using a condom I thought since he was an old school friend he was trustworthy. But I was wrong. I cried and cried. Two days later, I got a phone call from my friend and she told me about a person who is known by another friend, who can help me. I could not let my husband know what I was going through. I finally got his email address: spiritualherbalisthealers@gmail.com and I text this man my story and he replied me immediately saying i should be calm and told me that everything will be OK.
    I could not come to terms with what I was hearing but then I concluded it did not matter because I was so broken up I just needed help. I was going out of my mind literally. I was confused with what he was telling me, but I listened. He
    told me about some materials i need to buy that he needed to cast the spell and I said OK. I bought the materials to him, I sent down my picture to him and my positive result sheet and he replied me that i am going to be negative under 3
    days.I message Him every 2hours for 2day and I knew he thought that I was crazy but I did care I needed a shoulder. Behold, the third day he messaged me i should go for a test that i will be negative. My marriage could be broken because of a stupid mistake and my life was on the line. I remembered when I was going to get the results of my re-test I called him up again and told him that I was going to get my results today and his reply was “so” and that everything will be as he explained. I knew then that he was getting tired of me calling him, maybe I was wrong. Well I got my results and the first person I called up was him – again. As he said hello I started to cry and cry. I could not believe it. I was given a second chance in life.This man is a great spiritual HIV/AIDS healer,his healing spell on aids healing is very powerful .please brothers and sister, contact Dr Zuma zuk piritualherbalisthealers@gmail.com Or you can reach me through my email for advise slimcolvin@gmail.com
