German Doctor Cures an HIV Patient With a Bone Marrow Transplant

reporter writes "HIV is the virus that causes Acquired Immune Deficiency Syndrome (AIDS). Until now, HIV has no cure and has led to the deaths of over 25 million people. However, a possible cure has appeared. Dr. Gero Hutter, a brilliant physician in Germany, replaced the bone marrow of an HIV patient with the bone marrow of a donor who has natural immunity to HIV. The new bone marrow in the patient then produced immune-system cells that are immune to HIV. Being unable to hijack any immune cell, the HIV has simply disappeared. The patient has been free of HIV for about 2 years. Some physicians at UCLA have developed a similar therapy and plan to commercialize it."

Couldn't the recipients, who will generate the new bone marrow, then be used as donors?

Re:Like to see this replicated

[eln]

Right now, there's a ban on selling organs for donation in this country. However, bone marrow transplants are expensive. If the recipient could later be used as a donor, the ability to pay them for their marrow (thus allowing them to more easily pay for the original transplant) could really help move this thing along. Even if a marrow recipient is reluctant to donate his own marrow, if he had a very large medical bill and was offered money to donate, he would be much more likely to do so.

Of course, given the limited number of naturally HIV-immune people in existence today, it would drive up the price of a transplant in the short term as they demand high prices for their marrow, but in the long run it would even out as we create more HIV-immune people.

Re:Like to see this replicated

[DebateG]

I think the end goal is to use this method for autologous stem cell transplant (when the donor is the same as the recipient) rather than allogeneic (when the donor is different). Currently, there are technologies such as small interfering RNA (siRNA) that let you suppress a specific gene through genetic engineering. They are widely used in research, although there are many hurdles before they make the transition to clinical use. It would go something like this:

1. Draw out someone's own stem cells
2. Permanently express the CCR5 siRNA in their stem cells by culturing them with a virus
3. Wipe the person's bone marrow out by total body irradiation
4. Reinfuse the altered stem cells

The advantage of this method is that, since the stem cells are coming from your own body, there is no graft vs host disease (which is essentially like standard organ rejection, but instead the organ rejected is your entire body being rejected by the graft... you can imagine that this is very bad). Of course, you still have the problem of developing leukemia later from the total body irradiation and viral integration into an important gene. You also have a high risk of death upfront when you spend several weeks without a functional immune system when the transplant is taking. But nevertheless, it's exciting.

IIRC i watched a TV doc about HIV immunity and how it was found. there is a link to the black death here too.

AS it was discovered that the very same genes that help immunity from the black death are same for HIV.

if you have none of this gene pair "switched on" then you are gonna get ill quick and die......

if you have one of the pair on then you will go on for a few weeks THEN come down with symptoms.

However with BOTH genes switched on you are immune but carry the black death/HIV virus. Was on the discovery channel....

It was also apparently found that is was only ethnic Europeans who had this gene switched on... this led to some conspiracy theories about HIV/AIDS being created to be targeted at non whites.

Re:Like to see this replicated

[SlashBugs]

Background for non-biologists: HIV typically gains entry to cells by binding two molecules on the healthy cell surface. These are CXCR4 and CCR5. About 1% of white males (other genders/races vary slightly) don't have CCR5; they seem completely healthy and their cells are highly resistant to HIV infection. So blocking the activity of CCR5 seems like an easy way to stop viral infection with no exprected side effects. Tricky to do, but probably worth the effort.

Anyway, the answer is "yes", sort of. Several antibodies and small peptides are in trials to block the CCR5 receptor; some are showing promise in animal trials.

The most famous is Maraviroc, a small molecule that binds CCR5 and stops is from binding HIV. It's sold by Pfizer and currently in use as an anti-HIV drug.

Another interesting possibility is gene therapy. Another group has recently made CD4 T cells (one of the cell types that HIV infects) express a small molecule to block their own CCR5 receptors, which works very well. I haven't seen a paper on it, but you should also be able to use similar techniques to completely shut down CCR5 production (using virus- or plasmid-borne shRNA, for example).

Finally, another group has managed to make rabbits produce antibodies against CCR5 receptors (Vaccine
Volume 26, Issue 45, 23 October 2008, Pages 5752-5759). Those antibodies are able to bind to CCR5 and completely block HIV infection, which is great. Stimulating an immune response against the patient's own immune cells sound a bit dodgey to me, but my immunology isn't great: maybe there's a well-established way around this problem that I just don't know about.

Most of the drug treatments seemed like a viable strategy at one point. HIV mutates extremely rapidly though, and it seems able to bypass almost anything we can throw at it. If the new types of drugs can reduce the virus's ability to replicate effectively enough that it doesn't get an opportunity evolve a way round then in theory it could work. The problem with that is that you would need to administer the drug reliably on schedule for every infected person all the time and that doesn't happen. The treatments are expensive, and even worse, enough people see HIV/AIDS as some sort of punishment for promiscuity that some people are denied treatments intermittently because people don't feel comfortable giving it to them.

Re:Like to see this replicated

[ultranova]

Transplanting bone marrow to a HIV-infected individual should, IMO, be followed by a mandatory sterilisation. Else, we will be working against natural selection, and will in the long run assist HIV in surviving by increasing the number of non-resistant individuals in future populations.

This is not only stupid but also logically absurd, for reasons outlined below.

First of all, HIV-immune people appear to compose some 1 percent of the population, at maximum. That means that you'd be culling 99% of genetic variations from humanity, leaving the remainder much more genetically uniform and thus vulnerable for the next pandemic. And let's not forget that "immunity to HIV" is not like a feat in a role-playing game; it is a result of the particulars of your biochemistry, and likely has side effects, such as extra vulnerability to some other disease.

Secondly, if bone marrow transplantation makes you immune, then having no inherent, natural immunity isn't significant - everyone who gets infected gets cured and HIV will run out of hosts and die out. Being vulnerable to a treatable illness is hardly rational grounds for sterilization.

Thirdly, why treat HIV specially ? There are lots of deadly diseases out there. Should we sterilize everyone who is not immune to any one of them - which, I'd hazard to guess, would mean sterilizing everyone ?

Finally, it is impossible to interfere with natural selection. Natural selection means that the fittest have most descendants, and fitness is defined as having lots of descendants. "Survival of the fittest" is a tautology, you can't alter it. The only thing you can do is alter the environment, which then alter which characteristics make you fit.

Frankly, I'm beginning to see the merit in removing evolution from school curriculum and replacing it with creationism or whatever. We've seen crap like this since when the theory was first introduced; while some of it was purposeful, at least some had to have been caused by honest stupidity. Only teaching it on university level might act as a filter to keep it away from people who'll figure it means they should start an eugenics program.

cherry pick all you want. AIDS/HIV sufferers being denied treatment because of societal prejudices is well-documented. whether it's drug users, prostitutes, rape victims, or just ordinary women with HIV, people are being denied AIDS/HIV treatment because of the social stigma around these populations and their perceived lifestyles.

it's ignorant attitudes like yours that cause these prejudices to dictate public policy at the expense of public health. even if you don't care whether IV drug users live or die, giving them access to medical treatment in the name of harm-reduction is the beneficial to society at large. any rational person can see that eliminating potential disease vectors is a good thing.

denying prostitutes & drug users adequate access to medical treatment in order to punish them for their lifestyles is just cutting off the nose to spite the face. that kind of attitude has prevented the adoption of needle exchange programs in many areas despite studies showing that such harm-reduction programs save cities tax-payers millions of dollars each year by preventing the spread of disease--which inevitably affects non-drug users as well.

in many states you still need a prescription to get "Plan B"/"morning after pill"-type emergency contraceptives. which is dumb because there's a limited window of effectiveness for those type of drugs.

though there is a growing movement in the U.S. to make these drugs available over the counter. according to Wikipedia a nonprescription behind-the-counter preparation of Plan B is available in California to women 18 years or older. this was supposed to have been put into effect in 2006, but i haven't heard much about it. i just know that about 2-3 years ago my gf at the time had to get her prescriptions from a rapid-approval website, and (i think) it took about 6 hours between filling out the online and actually getting the prescription filled at a local pharmacy.

and if you don't like the idea of the conscience clause you're not alone. unfortunately, freedom of religion in the U.S. has turned into freedom to subject others to your religion. that's what happens when separation of church and state is flouted by a society. it starts with relatively innocuous things like adding "in god we trust" to our currency and injecting theocratic sentiments into the pledge of allegiance, but then quickly spreads to more insidious things, like encroaching on the rights of patients.

Re:Like to see this replicated

Well the GP of this post is not completely off. What they may be referring to is the fact that one prominent researcher's study came to the conclusion that HIV was not highly correlated to AIDS which suggested that HIV was not the causing the AIDS. Immediately he was kicked out of the scientific community as they stated that he should be jailed for life for trying to disprove a current hypothesis (which is the point of being scientific).

Part of your claim is mostly true. A prominent researcher (Peter Duesberg) did assert that HIV was not the cause of AIDS. His claims were not based on correlation between AIDS and HIV, however, because all prominent studies show an extremely high correlation -- people with AIDS invariably have HIV. Duesberg's argument was that correlation did not equal causation.

The second part of your claim is inflammatory and inaccurate. It is possible that some individuals expressed the sentiment that Duesberg should be jailed; this would be their own personal opinions. But Duesberg was not "drummed out of the scientific community" by any means. To this day he remains a professor of biochemistry and molecular biology at UC Berkeley.

Re:Like to see this replicated

[Mutatis Mutandis]

Excellent post, but I would just like to add a few more caveats. As you probably know, but most people certainly don't, HIV occurs in a wide range of variant strains, which use either CD4 and CXCR4 or CD4 and CCR5. This is a property called "tropism" and HIV strains are classified as X4 or R5 tropic.

But actually, from the data I have seen, few viruses exhibit a really pure tropism. There are a lot of dual-tropic X4R5 virus strains that have some flexibility to use CXCR4 or CCR5 as the opportunity offers itself; this is not surprising, as one variant must be capable of evolving into the other. Also, all patients carry diverse virus populations, because HIV is so sloppy in replicating itself, and a patient may well have 99.9% of R5-tropic viruses and 0.1% of X4-tropic viruses. (0.1% is about the limit of what can be detected with current, and very expensive, methods.)

This is cause for concern. A treatment that blocks the replication of R5-tropic viruses may well favour the replication of X4 strains. There already are indications that this happens in some patients on maraviroc treatment. Driving a virus population to become entirely X4 tropic would probably not be advisable, as there is reason to believe that these strains do more damage. The X4-tropic HIV strains are generally associated with the late stages of infection and the development of AIDS.

Therefore I doubt that anyone is going to advocated bone marrow transplants as a way to treat HIV. The risk is just too big, because this form of treatment is (almost) irreversible. Treatment with maravoric should always be preceded by tropism testing, and can be stopped if it doesn't work.

Finally, 2 years of undetectable viral load in absence of ARV treatment is an impressive result, but IMHO it is still too early to call the patient cured. He may well still have proviral DNA in his cells.

if your religion prevents you from performing the responsibilities of a medical professional, then you probably shouldn't be a doctor/nurse/pharmacist/etc. and AFAIK, pharmacists can quit their jobs or switch to a different occupation any time they want. no one is forcing them to be a pharmacist.

if you think that your religious freedoms include the right to deny someone else the medication they've been prescribed by their physician, then you are part of the reason why the conscience clause exists. freedom/liberty doesn't mean you have the right to do whatever you want regardless of the consequences it has on others.

and by your definition of slavery, then anyone living in a society governed by the rule of law is a slave. drug/food manufacturers all have to obey by strict sanitation and food-safety regulations even though they may not want to, but that's what it takes to protect consumers and public health. occupations like law enforcement and medical professions have even greater social responsibilities due to the vital nature of their work. if an on duty police officer sees a crime in progress they have a legal responsibility to step in, otherwise it may be criminal negligence. likewise, medical professional have certain moral obligations when they are on duty.

Words fail me. The DEFINITION of AIDS REQUIRES the patient to be 'HIV positive' in order for them to be diagnosed with 'AIDS'... i.e. it's a circular argument, moron...

If an organism has a disease and you can isolate a pathogen from that organism and then culture that pathogen outside the organism, then introduce that pathogen to another organism and the new organism exhibits the same disease... well, if you can do that, then Koch might say you're onto something. (This HAS been done with HIV/AIDS, by the way.)

By your logic, if the definition of having the flu requires that the patient be infected with a strain of the influenza virus, then it's a circular argument to claim that influenza causes the flu. So long as influenza can be isolated from any organism that doesn't have sniffles, then influenza must not cause flu.

Or to put it even more simply for you retards: TB death - HIV = TB death TB death WITH HIV = 'AIDS'

It is you who are making the circular argument. It is entirely possible to die of tuberculosis without having a compromised immune system -- in fact, it happens all the time -- and these deaths would not be classified as AIDS. A tuberculosis patient who does not mount an immune response is an anomaly, and then doctors must investigate why there is no immune response. Tuberculosis is not caused by a virus, and does not attack immune system cells, therefore a low T-cell count is not considered a symptom of tuberculosis. HIV is a virus and HIV has been shown to attack immune cells, therefore when a patient with both tuberculosis and HIV dies of tuberculosis after having failed to mount an immune response, it seems only logical to suspect HIV. But you argue that HIV does not cause AIDS, and in fact HIV is a harmless virus, and therefore someone who dies of TB with a compromised immune system who also has HIV could not have failed to mount an immune response because of HIV. What, then is the reason for the lack of immune response?

All the scientific evidence proves, beyond ANY doubt, that 'AIDS' is not a sexually transmitted disease, that 'AIDS' 'medications' are what kill people in the West

The article you cite is extremely easy to rebut. Like Duseberg's original claims, it does not cite any research later than 1997. HIV/AIDS research has come a long, long way since then. Furthermore, the article only focuses on research into AIDS cases in the U.S. Its hypothesis is that AIDS is caused by the use of AZT and other drugs, including recreational drugs. It furthermore claims that almost all AIDS is found in homosexual men and heterosexual drug abusers. The implication is that behaviors, including sex between men and drug use, are the cause of AIDS.

How does this article explain the AIDS epidemic in Africa, where AIDS is far, far more prevalent than in the U.S.? During the height of the African epidemic, Africans did not have access to AZT or similar drugs, nor did they use cocaine and amyl poppers in any great prevalence. Furthermore, in Africa the AIDS epidemic is primarily a disease of heterosexuals, including females.

How does a behavior-based cause of AIDS explain cases of AIDS in children and hemophiliacs?

How does this theory of AIDS explain why HIV+ patients have had longer lifespans since the beginning of the HAART (highly active antiretroviral therapy) era? If, as you claim, the cause of AIDS is in fact the drugs designed to cure it, then why does giving patients a combination of many such drugs make them live longer than they did when they had just one such drug (AZT)?

It's not quite as simple as that. As I understand it, there are different bone marrow types - just like you get different blood types - and for a transplant to be successful, you want to be transferring to someone with the same type. So for every HIV+ patient, you need to find a donor who is not only of the right type, but is also naturally immune.

Re:So you need immune bone marrow?

[DebateG]

Well, there are two problems with this. Firstly, hematopoietic stem cells don't last very long in culture. Lots of people are trying to figure out why, but I'm not optimistic that this problem will be solved any time soon since the cells normally exist in a complex microenvironment in the marrow that we don't really understand yet. But more importantly is the issue of MHC typing. While you need someone who has the CCR5 mutation (which is pretty rare), you also need to have someone who matches your MHC type. Think of MHC as the molecules that allow your body to identify self from non-self. The more MHC matches you have with the donor, the less chance you have of developing a life-threatening disorder called graft vs. host disease. Ideally, doctors want someone related to you, but if those people don't match, you have to do an unrelated donor search. Generally, finding a MHC match requires a large registry search that takes weeks to months to carry out, and many people, especially non-whites (due to the lack of representation of those elasticities in the bank), do not have a match.

[haaz]

My late mother had a bone marrow transplant (BMT) to treat her pre-leukemic condition and try to prevent it from becoming full-bore leukemia. To do this, they blasted her whole body with radiation (sorry, don't know which frequency), which killed her existing bone marrow. They then inserted/transplanted his sister's bone marrow. Now, I am not a doctor, so I'm probably leaving out a lot of important steps here. But because of the radiation dosage, she lost her hair, a lot of weight, and the ability to keep food in her for any length of time.

Yes, we knew this was coming. In fact, she had worked as a radiation oncologist for decades before her diagnosis with myelodysplasia. The irony abound.

Unfortunately, either the transplant didn't take or the weakness was too much for her. She passed away on November 16, 1999. Two weeks after I'd gotten married. And some of you may remember my then-wife from what happened five months later. Yeah, life kinda sucked.

I do want to see the HIV/AIDS pandemic curbed, and I do what I can to help people who have it live a little better. But a BMT is a major, major procedure. It's not guaranteed to be a death sentence, but it's not guaranteed to work, either. Is it worse than HIV/AIDS? That question is beyond my pay level to try and answer. I just have one story from one BMT that unfortunately did not go well. I am thankful that no one in my family has had HIV/AIDS.

Most of what I've read about so-called natural immunity isn't really immunity per-se. People with immunity still carry the HIV virus; It just doesn't turn into AIDS for a long time, but in a lot of cases, eventually it overcomes the immunity. Here's an article on one such study [BBC].

BMT is a major, major procedure.

With about 30% mortality, I've read.

Side effects of bone marrow transplant

[NigelTheFrog]

Ok, I'll admit this sounds like a neat concept for curing someone with HIV, but wouldn't you just be trading all of the consequences of having HIV/AIDS for the consequences of being a bone marrow transplant recipient? One of the most feared complications of bone marrow transplantation is graft-versus-host disease. The treatment for GVHD is...immunosuppression. So HIV patients who receive this treatment would have to face the possibility of being no better off than they were pre-treatment and potentially much, much worse (graft vs-host is a horrible condition).

Erm, this is Slashdot

What relevance do sexually transmitted diseases have here?

Re:I know what bone marrow transplants do to peopl

[ScrewMaster]

But I just don't know if this is the best way to deal with it once someone is infected.

I'd say it isn't, given the nature of a bone marrow transplant (such things always seems so easy on TV.) Still, there may be other ways to transfer this genetic protection to an individual (a retrovirus maybe) so this qualifies as significant progress.

Making money off of a disease which is very much kept in the vague, unclear, opaque situation is evil.
Where is the reproducible proof that HIV exists?
Where is the reproducible proof that HIV causes AIDS?

Go to the (American-run but internationally funded and popular) National Centre for Biotechnology Information here: http://www.ncbi.nlm.nih.gov/sites/entrez ...and type "HIV" into the search box. You'll get just under 192,000 peer-reviewd articles from groups all over the world, funded by various governments, public and private companies, charities and rich donors. Anything from HIV genome sequences and molecular sctructures through molecular biology, disease progression, transmission studies, all the way to local- regional- and global epidemiological studies. The evidence is pretty damn strong and well understood from the atomic level up to the global level.

Altenatively, click on the "Reviews" tab and it'll give you a mere 24,000 articles assessing, collating and criticising the others. Have fun!

True for HIV, True for HPV.
True for whatever.

When you've finsihsed the HIV evidence, feel free to look up the 15,000 HPV articles (or just 12,600 if you restrict your seach to "HPV AND cancer"). The HPV thing is actually very easy: most viruses carry genes evolved to push cells into their growth phase, because that forces the cells to release and synthesise resources that the virus must hijack to replicate. HPV-associated cancer happens when the viral gene gets incorporated into the cell's DNA (rare, but through well-established mechanisms) and get permanently switched on, making the cell grow and divide constantly. Any biology undergrad could tell you that if you asked. It's more common in the cervix simply because it's out of sight, and doesn't get noticed until it's really big and nasty. (Which is why all sexually actve women should be screened: catch it within the first 5 years and the cure rate is better than 98%. It's an easy cure if you *find* it)

THINK first. Do your research.

My undergraduate degree is in virology and I've just finished a PhD looking at how viruses interact with cancer and parts of the immune system. I've done plenty of thinking, and a hell of a lot o research. Now it's time for *you* to think, and for *you* to do some fucking research.

You're no better than the creatioists who say that evolution's impossible but have never botheres to get a fcuking clue how it actually works.

Re:Evolution.

[Thomas M Hughes]

Unless, by curing HIV, we're putting a halt to the next stage in human evolution. It could be that HIV was intended to trigger a dormant subsection of our genome.

HIV doesn't have intentions. It's a virus, not a God.

Re:Is it for real this time?

[TheLink]

I'm sure you'll find other incurable sexually transmitted diseases. For example: Hepatitis B and C.

So I recommend you:
a) use condoms
b) don't be promiscuous and pick a partner who isn't promiscuous
c) be abstinent

c) should be easy for most slashdotters :).

You know one kind of method for one kind of illnes

[Marrow]

I have had a bone marrow transplant. No radiation, minimal chemo-like drugs. In the hospital a week or a week and a half, 6 months of outpatient monitoring and I was cured.

For the AIDS treatment to work, they would most likely use something closer to my transplant protocol than the full oblation that they use with cancer patients.

Note to those interested: They dont have to go in with needles or drills to "dig out" the bone marrow from the donor. They give you a drug call the "G" that causes your bone marrow to percolate into your bloodstream. Then they filter it out with a dialysis-type procedure. Its fairly painless. I had it done to save my own marrow in case something went wrong with the transplant.

Quick answer

[PCM2]

STD cases are rising every year (NON-CUMULATIVE figures, of course), yet where are all the teenagers dying from 'AIDS'?

The fast answer is that HIV is not a highly contagious disease. In fact, compared to something like measles -- or HPV or active herpes -- it is actually quite difficult to catch HIV. The reason we focus so much attention on it, however, is because unlike herpes or genital warts, you die from it.

That is, until recently. Compared to 1981, we have quite a lot of experience treating AIDS. In fact, the clinical definition of AIDS an HIV-positive patient with fewer than 200 T-cells per cubic millimeter of blood. By definition, if we can stop your T-cells from dying, you don't get AIDS. (But if we stop treating you, you do.)

Other than that, it's 2008. To say that HIV does not cause AIDS at this late stage in the game is akin to denying evolution. The amount of scientific evidence linking HIV to AIDS is simply overwhelming.

I'm not at the tail end of a PhD in biology or anything close, but even I know this much. You do yourself a disservice by approaching scientific topics with blinkers on.
