Drug Makers Are Patient Advocacy Groups' Biggest Donors

Wednesday, October 21, 2009

Thai ALVAC-AIDSVax study published in NEJM this week.

From accompanying editorial (Raphael Dolin):
"The most important contribution of the study is most likely the opportunity to investigate possible host-response correlates of protection against infection. The establishment of such correlates is the central question in HIV vaccine development and will have a profound effect on the designs of vaccines andclinical trials to assess their efficacy.

Given the lack of detection of conventional immune responses in earlier studies of these vaccine components, as well as the divergence between the vaccine's effect on the infection and the effect on viral load, the correlates of protection may, indeed, reflect new concepts of host response. This should be the focus of intense research using the most current research techniques. Ultimately, it is the results of such studies that will most likely determine the significance of this clinical trial to the field of HIV vaccine development."

Kudos to Dr. Bob Siliciano and his Hopkins team for their persistence in pursuing this reservoirs issue

(Even if it is said that top retrovirologists view the eradication grail as unlikely ever to succeed)

Journal of Clinical Investigation (10/01/09)

From the Discussion section:

"Because of the high cost and potential toxicities of long-term HAART and the disappointing results from the clinical trials of HIV-1 vaccines and microbicides, there is still a pressing need for pursuing the goal of eradication.

To cure HIV-1 infection is exceptionally challenging and will likely require combining HAART with agents that can purge latent virus.

The identification of 5-hydroxynaphthalene-1,4-dione (5HN) not only expands the number of classes of latency-reversing agents but also demonstrates the possibility of utilizing pathway(s) further downstream of TCR stimulation to avoid global T cell activation.

Although the toxicities of 5HN raise concerns for its clinical application, this is a proof of concept for this approach to finding novel strategies to reactivate latent HIV-1 without inducing global T cell activation."

Can we start a HAART heart attack/stroke counter bulletin board somewhere public?

In the past 2 weeks alone I have heard of a 30-year guy (HIV+ on ARV therapy for many years) drop dead of a heart attack (myocardial infarction in the biz)-- in Utah no less-- and then just now, a very good friend of mine is being admitted to St. Luke's-Roosevelt after having suffered a light stroke (cerebrovascular accident).

I would need the hands and feet of an octopus to count all the other cases I have heard of--and this is just friends and friends of friends--over the past couple of years.

Yes, the debate about "Is it the 'chronic inflammation' caused by HIV itself or is it the drugs?" can continue on ad infinitum, but the truth is that people are dropping like flies. (Okay, not flies exactly, but suddenly and inexplicably and all too frequently!) And, let me tell you, it's not the LTNPs or those who took destiny in their own hands and have done on again/off again ARV rx to limit the long-term effects of these otherwise 'life-saving' medicines. (Totally unscientific conjecture here, I realize, but I will provide data to support it ASAP.) No, it's the folks who believed that all they had to do was start taking meds, take them with religious devotion, and everything would be alright. Their "chronic, manageable illness" would be managed and their life expectancy would be miraculously returned to normal.

My rant for the afternoon. But I am scared and angry.

New York Times hits 2 key issues, in B1 cover page stories, 2 days back to back:

The problems with clinical practice guidelines: Turns out one size doesn't (and never did) fit all. And the problem is only compounded by tainted panel members

by Barry Meier

The epidemic of ghostwritten medical 'research' papers in esteemed medical journals continues unabated

by Natasha Singer

Friend, mentor and comrade in arms, Dr. Joe Sonnabend, has been ahead of the curve on this clinical practice guidelines nonsense, as he has been on most everything, for a long time now. It's a shame nobody seems to listen. Check out Joe's new Poz blog. I hope people everywhere will read (and heed) it!!

Which comes first? The wrists & ankles snapping like kiln-dried twigs? Or the early mid-life, out-of-the-blue stroke & heart attack?

(I have heard of two new heart attacks, friends of friends in their early 40s, in just the past month. And yet another friend dropped to the sidewalk unconscious in Tribeca last summer after suffering a stroke. He is not even 40!! He had blacked out, didn't know who or where he was -- and still cannot speak properly or use his right hand.)

Someone really has to find a better way to manage this infection or, at the very least, help us to protect ourselves against all these nasty side effects.

Where have all the community-based research institutes and amFARs (oh, sorry, Amfar recently dropped the 'Am' in order to reposition itself to tap into the boondoggle of international HIV/AIDS funding and recently re-branded itself the "Foundation for AIDS Research" aka FAR) gone??

We all know the answer: picking the low-hanging fruit (big reward for only somnambulant effort) by signing up for Big Pharma "me too" trials that any lobotomized blind monkey could do with one hand tied behind her back.

Where are the activists?

Loss of Bone Mineral Density After Antiretroviral Therapy Initiation "Independent of Antiretroviral Regimen"


Source: JAIDS, August 2009 - Volume 51 - Issue 5 - pp 554-56

Free abstract here.

From Conclusion: "Similar decreases in BMD over 96 weeks occurred in ART-naive subjects receiving either EFV-based regimen or LPV/r-based regimen, which was not altered by simplification to LPV/r monotherapy and was unrelated to markers of tumor necrosis factor-α activity."

Comment: But if, as many of my smartest and longest serving HIV care providers believe & observe in their (very large) practices, the biggest CULPRIT here (in terms of loss of BMD) is TENOFOVIR (as in Viread, Truvada, Atripla), this study's conclusions are not all that helpful-- as both PI and NNRTI based regimens are very likely to have included TDF+FTC (or TDF+3TC). Still, we cannot be certain until we have seen the full paper or spoken with the investigators. -MB
