You Just Can't Trust Biologists

What with anthropogenic global warming and evolution of species, tens of millions of people now think they understand science much better than scientists do. Sometimes they figure things that way because they trust their interpretation of God's infallible word, as translated into English, more than opinions of any number of scientists, but often enough they figure scientists just lie to them for political or religious reasons, or don't understand science quite as well as they do.

Consider HIV and AIDS. Amazing numbers of people remain convinced that HIV does not cause AIDS but that anti-retroviral drugs do. Several South African countries have made AIDS denialism national policy, with predictable effects.

New Scientist calls denialism "a lethal delusion" and recently addressed denialist arguments one by one, perhaps in hope of reaching some people who might otherwise die. Denialism has long been based on ultra-strict application of Koch's postulates relating to bacterial infection (not viral infection), notwithstanding widely recognised and understood limitations to their use. Koch's postulates were:

"The bacteria must be present in every case of the disease.
"The bacteria must be isolated from the host with the disease and grown in pure culture.
"The specific disease must be reproduced when a pure culture of the bacteria is inoculated into a healthy susceptible host.
"The bacteria must be recoverable from the experimentally infected host."
Thus, denialists would refuse to accept that HIV caused AIDS unless "healthy susceptible hosts" were intentionally infected for experimental purposes.

Even so, New Scientists rebuts every denialist argument. HIV doesn't cause AIDS because not every person with AIDS tested positive for HIV? When U.S. Centers for Disease Control tested 230,179 cases of AIDS-like symptoms, 47 tested negative for HIV, around 0.025%. No proof HIV even exists? We have no proof that influenza, smallpox, yellow fever, or measles viruses exist either. Anti-retroviral drugs kill? Death rates among 1,255 test subjects dropped from 29% per year to 9% per year when patients got anti-retrovirals. HIV tests don't work? Western blot produces 1 false positive per 1,000 tests. Poverty and malnutrition cause AIDS? Highest AIDS rates in Uganda were among middle-class government employees rather than poor people, and AIDS rates skyrocketed 57% in South Africa from 1997 to 2002 even as poverty rates fell. That Western countries haven't experienced epidemics similar to that in Africa calls orthodox opinions into question? Different strains of HIV may cause different effects, and "concurrency theory" may also explain this anomaly.

This story illustrates how unwilling many people have become to let facts interfere with their preconceptions and beliefs. For every scientific belief that ultimately gets successfully disproved by dissidents, ten hold up in one form or another indefinitely. No, Virginia, Earth has never stood at our Solar System's centre. People who thought so 1,000 years ago were just as wrong as people who think so today, yet people still cling to this notion, science be damned. Some things really never change.

I'll break it down point by point of Koch's postulates why HIV deniers using Koch's postulates is retarded. Also, I added "virus" after bacteria in his postulates to clarify things.

HIV doesn't cause AIDS because not every person with AIDS tested positive for HIV? When U.S. Centers for Disease Control tested 230,179 cases of AIDS-like symptoms, 47 tested negative for HIV, around 0.025%.

"The bacteria [virus] must be present in every case of the disease."
If anything this is testament to the amazing lab quality control the CDC does. The false positive rate for PCR, Antibody tests, and all the other HIV testing methods is much higher than this in normal settings. Also, Koch's postulate says "The bacteria [virus] must be present in every case of the disease" not "The bacteria [virus] must be present in every case of the disease or the guy is magically cured if the lab tech fucks up the test."  Labs screw up. It happens.

"The bacteria [virus] must be isolated from the host with the disease and grown in pure culture."
Viruses don't grow by themselves in liquid culture like bacteria do. Duh. Don't be fatuous, HIV deniers.

"The specific disease must be reproduced when a pure culture of the bacteria [virus] is inoculated into a healthy susceptible host."

See #2. Also, perhaps an HIV denier would volunteer for this experiment because it sure as hell would not pass a human review board.

"The bacteria [virus] must be recoverable from the experimentally infected host."
See #3. Although I'm sure after a month or so the experimentally infected HIV denier would test positive should they wish to volunteer.

People do have this odd impulse to believe what they want to believe, because this makes the world seem more fair, more sensible, or more satisfying to them personally, than it would if they believed what objective observation and logical reasoning would indicate.  Another factor is the sheer complexity of the real world, which many people find incomprehensible, particularly in comparison to nice, simple fairy tales that are told to them by their religion or by other charlatans, which make things seem so much simpler.  And these people know that they are right because they just feel that they are.  Gut feeling transcends all logic.  I have more than once had arguments with people (not on this web-site) who advocated a non-scientific viewpoint and who, after discussing it with me, told me that my arguments were more logical, more persuasive, and better stated than their arguments, and they can't prove that they are right, however, they still think that they are right.  It's a fascinating phenomenon.

Of course, reality doesn't mold itself to suit our fantasies, and those who have ridiculous beliefs quite often suffer a rude awakening, as is certainly the case among those who cling to non-scientific theories about AIDS.  This current delusion is also rather like the Boxer Rebellion, a historical incident in which a group of Chinese rebels against British colonial rule decided that they were just too virtuous to be harmed by guns, since those weapons were used so unfairly by the British to overcome the culturally superior Chinese, and therefore the Boxers just would be immune to bullets.  Bullets killed them anyway.

It's a crazy world.

"Anti-retroviral drugs kill? Death rates among 1,255 test subjects dropped from 29% per year to 9% per year when patients got anti-retrovirals. "

The study you quote here does not support these conclusions.  I will link to the abstract: http://content.nejm.org/cgi/content/abstract/338/13/853 .  This is not a controlled, double-blinded clinical true.  It's a surveillance report that follows very ill patients from January 1994 through June 1997.  You might know that during this period of time, high dose AZT, which proved to be extremely toxic, was phased out in preference for lower doses of AZT, and newer, less toxic drugs.  This study lacks the statistical power to disprove the hypothesis that the drugs and doses given to patients in 1997 were simply less toxic.

From the study itself:


During the study, the pattern of antiretroviral therapy changed dramatically among patients with CD4+ cell counts below 100 per cubic millimeter. The proportion of patients for whom any antiretroviral therapy was prescribed increased, from 72 percent of patients in 1994 to 95 percent by June 1997, with marked increases in the prescription of combination regimens (from 25 percent in 1994 to 94 percent by June 1997). The most dramatic increases were in the rate of use of regimens containing protease inhibitors, from 2 percent in mid-1995 to 82 percent by June 1997.

What were these patients transitioning from?  High dose AZT - because that's all there was previously.  So I propose that all this study does is show that protease inhibitors were much less toxic than high dose AZT.

If you'd like to prove to me that ARVs save lives, please forward me a reference for long term study (3 or more years) which is double blinded and placebo controlled, that compares a single ARV to a proper placebo (not other ARVs, but standard of care for any opportunistic infections that arise), which demonstrates statistically significant reduced mortality in the treatment arm of the study.  I've been asking for such a reference for years - and have yet to find one.

You will however find studies that come close, but that compare one drug to other.  The new drugs generally have lower morbidity and mortality rates - which again does nothing to falsify the hypothesis that the new drugs are simply less toxic than the old - which hell, is a stated goal of the pharmaceutical manufacturers.  Until you compare the drugs to no drugs, you haven't proven scientifically that they save lives.

So, if you want to claim the scientific high ground, please don't reference uncontrolled, unblinded surveillance reports.  Stick to clinical trials that prove that these drugs save lives over the long term.

"HIV tests don't work? Western blot produces 1 false positive per 1,000 tests"

And that's a good thing?  And this is the best test.  ELISA is much worse.  If we tested everyone in the US with a western blot test, that would lead to finding 300,000 false HIV carriers.  And despite Newscientist's protestations, there are still documented cross-reactive conditions and infections.  For example, pregnancy can make you more susceptible to a false positive.  A TB infection is also another source of false positives.

The false positive rate is why we generally don't test outside of the risk groups.  If for example, you have a population which has a lower natural infection rate (say for simplicity sake - 1 in 1000), and you test all of them - about 50% of your positive test results will be false positives.

Cool. You get the couple thousands of HIV+ patients who are willing to forego medical treatment as part of a control group and find me an IRB psychotic enough to do it and you'll get your study.

But you won't. It will never happen. Ethics don't allow it. Think Tuskegee experiment x 1000. Common sense doesn't allow it. You have to compare new treatments vs the current "gold standard" and see if it is better or worse. No ethicist is going to sign off on what you propose. It would be insanity.

You are not the first person to claim that properly controlled clinical trials are unethical.  But, until such studies are conducted you do not know whether or not such drugs cause more harm than good.  Not conducting such studies is unethical.  Continuing to administer these drugs in the absence of such evidence is unethical.

The first ARVs should have been compared to placebo plus standard of care at the time for whatever OIs arose.  Those studies were not conducted.  The one that comes closest was the Concorde study, which was ended early, compared early AZT to late AZT ( a kinda placebo), and in which the blind was compromised by the massive adverse side effects of the drug.  Everybody, doctors and patients knew who was on what drug.  

Since this time every new drug has been compared to previous drugs, and tested against surrogate markers, usually over a short period of time.  There are no long term placebo controlled double blinded studies of any of these drugs.  Until there are, you simply cannot make the claim that these drugs saves lives over the long term.  There is no scientific evidence to back you.  Attempting to gather that evidence is not insane, it is not unethical - it is required by science.  But HIV medicine has long been mostly about politics, not science.

I'm confused about why your proof requirements are so specific.  Why is, for example, this study, which found that more active types of ARVs increased the life expectancy of those with HIV, not good enough?

Logically, if the increased ARVs increased life expectancy, those drugs help, regardless of whether the old ones did or not.  So even though that study is a comparison of two treatment regimens, the fact that one works better than the other means it works better than nothing as well.

" So even though that study is a comparison of two treatment regimens, the fact that one works better than the other means it works better than nothing as well."

Only if one of those regimens has first been compared to a placebo or the previous standard of care.  In the case of ARVs - this has never occurred.

Sure as far as it goes this statement may be correct.  Newer drugs do appear to kill fewer people than high dose AZT.

Are "more intensive" ARVs less toxic than high dose AZT.  Yes.  Was drug toxicity controlled for in this surveillance report?  No.  Does the study support the conclusion that drug efficacy and drug efficacy alone resulted in lower mortality?  No.

So you've just magically decided these drugs kill people based on what?  I mean, any drug is going to have side-effects, but I'd love to see evidence that these drugs are going to kill people faster than HIV will.  Moreover, and this is something you've suspiciously failed to address, people with HIV on those drugs have a greater life expectancy than people with HIV who are on no drugs whatsoever.

"So you've just magically decided these drugs kill people based on what?  "

AZT kills people.  It was a failed chemotherapy drug.  I leave you to google the life threatening side effects of more modern ARVs.  They are toxic drugs.  Toxic side effects kill people.

"I mean, any drug is going to have side-effects, but I'd love to see evidence that these drugs are going to kill people faster than HIV will"

You've got it backwards.  You don't assume that the drugs will save lives and then demand evidence that they don't.

" Moreover, and this is something you've suspiciously failed to address, people with HIV on those drugs have a greater life expectancy than people with HIV who are on no drugs whatsoever."

The study that you link to is not evidence of that.  I am more than willing to evaluate such evidence from properly controlled, double blinded clinical trials.

HIV has an effect: Death. Drugs have side effects. It's a risk v. benefit calculation. Who gives AZT to somebody not infected or exposed to HIV? Same thing can be said about a bunch of other medications given to kids --- I'll wager that without the drugs I took as a kid to get reduce my then chronic asthma I would not be alive today. Of course, they had bad side effects and at least one could have killed me but thats why it is a risk/benefits thing coupled with intensive monitoring.

You still have failed to address the evidence, from the study I linked, that people live longer on those meds than on nothing.  

If that's not enough, here's another.  Quoting: "Where available, highly active antiretroviral therapy has resulted in significant decreases in HIV-associated morbidity and mortality."  The same study says that development of highly-active retrovirals reduced HIV mortality by 80%, and raises life expectancy from 9-11 years upon diagnosis of HIV to more than 20.

So, I have provided more than ample evidence that retrovirals increase life expectancy on the whole.  I now defy you to show me evidence that they do not.  On what are you basing this belief of yours?

"You still have failed to address the evidence, from the study I linked, that people live longer on those meds than on nothing."

No, I've addressed it again and again, and I quoted, in detail, from that study.  Let me do so again:

" The proportion of patients for whom any antiretroviral therapy was prescribed increased, from 72 percent of patients in 1994 to 95 percent by June 1997, with marked increases in the prescription of combination regimens (from 25 percent in 1994 to 94 percent by June 1997)."

So the number of people on drugs went from 72% to 95% - and at the same time there was a marked shift from the older therapy (AZT) to combination therapies - 25% to 94%.  Again here this is not a controlled clinical trial, so whatever you want to take from this mess - it cannot prove anything scientifically, about all it can do is suggest avenues for further study.  But I don't understand why you are fixated on the increase from 72% to 95%, instead of the increase from 25% to 94%.  This surveillance report cannot falsify the hypothesis that combination therapies, using lower doses of AZT, and newer, less toxic drugs, were simply less toxic than previous therapies.  The decrease in mortality could be solely due to the increased usage of less toxic treatment regimes, from 25% to 94%.

Your other link is more of the same.  It's not a controlled clinical trial.  You seem not to understand the need for controlled clinical trials when seeking evidence for drug efficacy.  I don't really know how to explain this to you.

"So, I have provided more than ample evidence that retrovirals increase life expectancy on the whole.  I now defy you to show me evidence that they do not."

No you haven't.  Please provide a link to a long term, placebo controlled, double blinded study that demonstrates decrease morbidity/mortality in AIDS patients as the result administration of a specific ARV.  This is the sort of proof required by science.

"On what are you basing this belief of yours?"

You are the believer, I am the agnostic.

I'm not familiar with the study, but it is common in medicine to halt a study early if a drug shows great promise and switch the placebo folks over to it. It's the ethical way to do it otherwise you're watching people die while you potentially hold their salvation in your hands. I doubt you'd find a physician who is enough of a monster to do what you are proposing.

OK. Pehaps you'd like to volunteer for the experiments proposed by nightlily and be a part of the Koch's postulates study? After you come down with HIV you can refuse treatment and we can compare you to a regular person who takes ARVs. All in the name of science, right?

"Oh my gentle Jesus. You're advocating withholding treatment from HIV+ people for the purposes of "science?" Really? No ethics board will approve that. That'll make Tuskegee and Willow Brook look like a picnic."

No, I am advocating that these drugs be subject to proper clinical trials, like every other drug.  Such a clinical trial should include a placebo arm which uses a placebo and otherwise treats patients with the pre-ARV standard of care for opportunistic infections.  Until such a study is conducted, there is no basis to claim that ARVs save lives over the long term, there is no basis to claim that you are not doing more harm than good.  You seem to operate with a world view that accepts that ARVs are known good, and withholding them is evil.  There is no science to support that belief.

I will offer this one caveat - these drugs are remarkably cytotoxic - they kill cells.  They kill fungus, bacteria, and host cells.  As such they are powerful broad spectrum antibiotics/antifungals.  The existing body of studies supports this as there are short term positive effects of taking these drugs.  But most studies are just that, short term.  And these drugs aren't used over the short term, you are supposed to take them for the rest of your life, during which time the toxic side effects of killing your own cells may catch up with you.  

But I will admit that existing studies do possibly support the short term use of these drugs to knock out particularly bad opportunisitc infections if more conventional treatments are not effective.  But that's not the way we use these drugs.  

"I'm not familiar with the study, but it is common in medicine to halt a study early if a drug shows great promise and switch the placebo folks over to it."

The study was a mess.  It was unblinded by side effects and patients started sharing medication as well.  Also, comparing late therapy to early therapy is no kind of placebo.  The very design of the study indicates the political pressures that were being brought to bear at the time.  Even though AZT was the first drug of it's kind and had never been proven effective, people were still convinced it would be unethical to withhold the new "miracle drug" for too long.

"OK. Pehaps you'd like to volunteer for the experiments proposed by nightlily and be a part of the Koch's postulates study? After you come down with HIV you can refuse treatment and we can compare you to a regular person who takes ARVs. All in the name of science, right?"

Do you imagine this to be some sort of rebuttal to my argument that double blinded, placebo controlled clinical trials are required to demonstrate drug efficacy?  If in the future I develop a fatal disease, I will be more than happy to enter a properly controlled clinical trial of a new drug.  Perhaps I will get the drug, perhaps not - either way I'll probably get excellent care, and whatever my personal outcome my involvement in the trial will help determine whether or not the drug is effective.

What I cannot get through my head is why there is this bizarre a priori assumption that all new drugs are good. Until the clinical trials are conducted, we don't know if the drug is good or bad, and it could be very bad.  So, being in the placebo arm of a study of such a drug could be a blessing.

And honestly, stop harping on Tuskegee.  Was Tuskegee a double blinded, placebo controlled clinical trial?

So what you are saying is that no comparison has ever been done between the old medication and no medication at all. Just between the new medication and the old.

But hasn't AIDS mortality dropped rapidly since the introduction of the medication? Isn't the "Death rates among 1,255 test subjects dropped from 29% per year to 9% per year when patients got anti-retrovirals" a comparison between no medication and medication, showing a very significant change? Even without double-blind medical tests, I'd say that says a lot about whether the drugs have a positive effect.

To what alternative factors do you attribute the fall in AIDS mortality? It seems to be a bit strong for a placebo effect, and infection rates did not show a similar drop. How is this success not a proof for the medications effectiveness?

If not, how can you tell when he means what he says and when he doesn't? Maybe it doesn't matter?

Do you figure that about Alf as well? His affinity for UFOs, cryptozoology, and conspiracy theories, his general alienation, his racialist animus, was that all crap too?

Fierce? If nothing he says counts for anything, "waste of time" seems more descriptive.

Lived (post 13). WAY different from "visited", eh, Mr. Clinton? I guess you needed to second Goro. Fine. I'll take it from there.

"But hasn't AIDS mortality dropped rapidly since the introduction of the medication? Isn't the "Death rates among 1,255 test subjects dropped from 29% per year to 9% per year when patients got anti-retrovirals" a comparison between no medication and medication, showing a very significant change? Even without double-blind medical tests, I'd say that says a lot about whether the drugs have a positive effect."

The 29% per year was in the high dose AZT era.  AZT was a failed chemotherapeutic agent.  It was too toxic.  Too toxic to be taken briefly to attempt to knock out cancer.  And then in the AIDS era we have AIDS patients taking it continually.  The rapid drop in mortality corresponds to the advent of protease inhibitors and combination therapies that drastically reduced or eliminated the dose of AZT (as the study notes in the portion I quoted).

So what you are saying is that we have no numbers about AIDS mortality when it is untreated, e.g from the 80s when the illness was just newly discovered?
