Drugs May Offer AIDS Prevention 230

Posted by Zonk from the here's-hoping dept.
FlipFlopSnowMan writes "There is an interesting article on MSNBC about the possibility of preventing AIDS using the same pills that are currently used to fight the virus in affected individuals." From the article: "The drugs are tenofovir (Viread) and emtricitabine, or FTC (Emtriva), sold in combination as Truvada by Gilead Sciences Inc., a California company best known for inventing Tamiflu, a drug showing promise against bird flu. Unlike vaccines, which work through the immune system -- the very thing HIV destroys -- AIDS drugs simply keep the virus from reproducing. They already are used to prevent infection in health care workers accidentally exposed to HIV, and in babies whose pregnant mothers receive them."

    The evidence that AIDS drugs can prevent infections comes not only from exposed health care workers, but also monkey studies. If monkeys are given AIDS drugs up to 48 hours before exposure to SIV (the causitive agent of simian AIDS), they fail to become infected. That has been known since the late 90s. There is some data suggesting that the drugs can't always protect against multiple exposures to SIV, but those studies used only one drug at a time (not a cocktail of pills, like you would take if you had HIV).

    As an HIV researcher myself, I realize that we are not going to have a highly effective, preventative vaccine for HIV any time in the near future. There are no clear 'winners' in the pipeline right now, and even if a vaccine looked effective right now, it would be years (and millions of new infections) before it clears human testing and it broadly available. Issues like viral resistance to the vaccine, incomplete protection from infection, potential side effects, and a false sense of security would plauge any vaccine that is developed -- and these are many of the same issues confronting the use of drugs as HIV preventatives.

    One major hurdle to testing these drugs in populations highly affected by HIV is to convince them that this intervention is not a magic bullet. There will be problems, some of which we probably can't predict. There will be breakthrough infections in people taking the drugs. And the long-term health consequences aren't known. So far, these concerns have led to the abandonment of several trials of PrEP (using tenofovir in HIV-, high-risk populations) around the world. Hopefully the new data (using multiple drugs together works better than tenofovir alone) will encourage vulnerable populations that the potential benefits may outweigh the risks.

It is a way of life for thousands of scientists, a huge cash cow for drug manufacturers, and a political plank for both gay activists and gay-bashing activists.

    If you are open to the idea that the orthodoxy about AIDS might not be correct or might not be scientific, then I suggest you read these two pieces of investigative journalism that came out a couple of months ago.

      What a bunch of tripe. Michael Moore would be really proud of the first paper. (I didn't read the second one, sorry) I can excuse the writer if 1/2 of the inaccuracies are from an ignorance of the field, but it honestly seems like she's trying to dissuade. Virtually every 3rd paragraph contains and inaccuracy or inappropriate insinuation that is subtle enough to be missed by someone who isn't trained in these fields. The author focuses her arguments by looking at small segments of the literature and history and ignoring the broader sweeps. For example:

      The paper's initial assertion is that AIDS was introduced as a polio virus. Simple logical disproof: 1) polio vaccine is given across social/habitual classes. 2) There has not been 1 case of AIDS where the person didn't have one of the following three risk factors: blood transfusion, risky sex*, IV drug use. 3) Not everyone in the US has previous three risk factors. 4) If 2 is true 1 or 3 must be false or at least excruciatingly improbable. 5) 3 is true, therefore 1 must be false. QED. (*risky sex = sexual activity where both partners are not exclusively monogamous to each other at any time during or prior to their relationship)

      Several pages deal with the controversy surrounding the initial discovery of the HIV virus. There was also controversy surrounding the discovery of DNA, therefore we shouldn't believe DNA is the 'source code' of life?

      She makes light of the microliter aliquots used in the CBC tests but fails to mention that all CBC tests (test which count the types and number of cells in your blood) uses these metrics. We shouldn't trust tests for hundreds of diseases including leukemia, polycythemia, or even iron deficiency based on this implication. (for example, look at the normals on this page: http://www.saintfranciscare.com/11377.cfm [saintfranciscare.com])

      She also does not respect the validity of the HIV Load test, saying that since it uses PCR (a very common technique in medicine) it cannot be accurate. (no more genetic testing, goodbye cancer diagnosis, goodbye endocrinology) She also asserts that the HIV Load assay will give false-positives and is inaccurate if the procedures are not followed. Yes, it does give false positives, it is a HIGHLY sensitive test, with a low specificity. It is not a screening test, and it cannot be used for one because of its high false positive rate. Additionally, I challenge anyone to find a test in any field that is valid when its procedures are not followed. (magnetism doesn't attract wood, therefore magnetism is false)

      But the coup-de-gras for me was her statistics that showed how low CD4 counts don't correlate to AIDS. (AIDS is, incidentally, practically being defined by low CD4 count)

      * "61% of people with CD4 count = 200 in 1997 were AIDS free"
      * -response: Yes, CD4=200 is the upper limit at which you see AIDS symptoms, this is expected

      * "190,000 Americans in 1993 with CD4 count=200 were AIDS free"
      * -response: See above, plus in 1993 the AIDS definition was changing so you see changes in the statistics. Additionally, that number is far less than a quarter of the number of AIDS cases in the US that year. (http://wonder.cdc.gov/wonder/data/aidsPublic.html [cdc.gov])

      * "No studies have been done to show removal of anti-retrovirals = disease"
      * -response: No, but anti-retovirals have been tightly correlated to increased CD4 counts, and their withdrawal to lower CD4 counts. It has also been shown repeatedly (and even in this paper!) that low CD4 count correlates with disease.

      what if one of the various "environmental factors" models is right rather than the "single pathogen" model?

      That's just not a serious possibility anymore; here are just some basic observations:

      • While clinical diagnosis relies on symptoms, HIV infection has been followed in minute detail from initial transmission to death numerous times, in the presence and absence of treatment, in individuals with completely different histories, at the molecular level, at the tissue level, and at the clinical level.
      • The epidemiology of HIV has been studied extensively: the disease is clearly transmissible and no other factor than an existing HIV infection is associated with transmission.
      • Drugs specifically targeted at HIV have increased survival rates tremendously, while changes in lifestyle have had limited effect.
      • The molecular mechanisms of resistance to HIV infection (found in a few percent of the population) are well understood.


      Single pathogens are sexy for epidemiologists.

      Yes, and they are also the rule for infectious diseases. While susceptibility and severity of a disease may vary with environmental factors, for infectious diseases, there is usually a well-defined, clearly characterizable pathogen responsible.

        Well, that's just not true, and the fact that people keep repeating it doesn't make it so.

        • The presence of antibodies is not a determinant of virus load (and in the case of newborns of mothers with HIV, is not even an indication of the presence of the virus).

    as an AIDS counsellor, I've worked with many people who are taking these drugs on a daily basis. While they are a brilliant development and have already saved millions of lives, they are EXTREMELY TOXIC; they are totally unsuitable for preventive purposes, apart from being very expensive, they require regular blood tests for specialised medical monitoring (to check your body's responses, get the doses correct, etc), and there are often really grim side effects (such as vomiting, diahoerrea, nausea, fatigue, depression, etc etc); I know many who have chosen to come off the drugs because the quality of their life had got so bad from the side effects that they would rather die with a bit of diginity.

    They hammer your immune system; it's like taking poison every day, it's a bit like chemotherapy in ways.. in fact, that's not a bad analogy: why don't we all start on an ongoing course of chemotherapy as a preventive measure against getting cancer?

Anyway, a long time ago, my girlfriend at the time and I were hanging out outside a bowling alley waiting for a ride home and she put her hand down on a hypodermic needle. Now, there was no way of telling whether this had been used for insulin or heroin, and she had to go into a regimen of anti-hepatitis and anti-HIV drugs.

    Expect immediate, heavy resistance from the ultra-right wing, Christian conservative political forces in the US. Experience has shown that if there's a disease that increases the potential negative consequences of having sex, especially those which disproportionately affect women, they will oppose efforts to provide treatment. (Women in heterosexual relationships carry an increased risk of HIV transmission when compared to men, although they have a decreased risk in homosexual relationships. The reasons I leave as an exercise for the reader.)

    Case in point: the human papilloma virus, or HPV. Now here's the thing with HPV: it's sexually transmitted, condoms don't protect against it, and doctors believe that it's responsible for seven out of ten cases of cervical cancer later in life. So, if we could develop a vaccine against it, that would be a huge strike against cancer, right?

    Well... sure. But ultra right groups like the Family Research Council oppose such a vaccine, even though pharmaceutical companies have already conducted successful clinical trials. Why? Because they want to scare people into not having sex.

    If this is the reaction an HPV vaccine (or, for that matter, condoms) gets, how do you think they're going to react to a cure to something which disproportionately affects gay men?
    • The alternate nut job theory is that greenies are preventing the vaccine from coming to market.

      After all, it has accellerated the population balance in Africa and South East Asia by increasing the death rate.

        There's good reason for that. Last I checked, for example, it's really hard to get HIV by having someone cough on you [state.fl.us].

        I suppose I should ask for clarification: what do you mean by "Typhoid Mary's?" Are you suggesting that people with HIV should be quarantin

    • There was a recent article in The New Yorker about the Bush Administration's relationship with science in the US. One person who was not a member of the Admin but did advise them on medical issues said, when asked about an HIV vaccine, that they would have to take a very hard look at it before recommending the FDA allow its release to the public, for exactly the reasons you say. So yeah: you're entirely correct.
