So here we are, two years after the scientific community was told which rock to look under, still arguing about whether two or three scientists can reproduce their work or not. In the meantime, a promising avenue of treatment, antiretrovirals, has been shut down like a prohibition, for the flimsiest of reasons. Too dangerous (compared to what?). Too expensive (for whom?). AIDS patients need their drugs (since they have a serious illness). How can we treat it if we don’t know the precise agent we are treating? The way doctors treat people every day. Best guess. I actually think we have a better model than the rheumatologists are using to prescribe incredibly toxic drugs for patients with autoimmune diseases.
AIDS patients have to be treated forever, but we don’t have any idea if that is true for us or not. Just think how much we’d know now if part of the money that was spent trying to find a virus that doesn’t exist in nature could have been spent on very simple clinical trials of safe, existing drugs. It is becoming clear that at least some are concerned about lab contamination by viruses that are very good at infecting human cells in vitro. See Zhang and Sfanos on the side bar. It’s about time somebody worried. Whatever works, and fear is a good motivator. It worked for HIV.

I still think it’s simple retroviruses at the bottom of it, and maybe not just gammas. Simple retroviruses go for the germ line and become endogenous. Multiple assaults. Most end as ineffective sequences, with deletions, tamed by restriction factors that give an individual’s offspring an evolutionary edge. ERV’s can be defective and still cause disease. They can even become symbionts:

Defective sequences can be reconstituted by new incoming. It is not as simple as one sequence or one virus, or even five strains of one virus. Lots of viruses and pieces of viruses. Lots and lots of exposures, if it came from vaccines, grown in all kinds of cells, murine and avian, administered parenterally to most of the human race for decades, and subject to recombination. There were clearly waves when people got sick, but those may have been recombination events, when some necessary piece was supplied to reconstitute something that was there already. Or maybe there were waves of helper viruses that went out and turned on what was there. Or particular environmental toxins that activated one from an earlier invasion (from the Weiss paper above: “..we were able to show that treatment of normal chicken cells with a variety of activating agents such as ionizing radiation or carcinogens stimulated release of virus..”).

Could antiretroviral drugs be effective in multiple sclerosis? A case report. Maruszak: This is a letter to the editor behind a paywall, but documents the resolution of significant neurologic impairments, including bladder and bowel incontinence, in an MS patient after being treated with HAART for HIV infection. The patient developed MS and was infected with HIV in ’85. He was treated with HAART in ’96, improved rapidly with resolution of many MS symptoms, including fatigue, within two years. It happened in the late ’90’s and it was just published… It is the only paper I could find where anyone has documented an effect of arv’s on MS, despite the fact a retrovirus has been suspected for over a decade. How’s that for blinders! What is it about this particular class of drugs that has everybody so spooked? Is it because AIDS patients have to take them forever? It may not be the case here. The best anecdote I’ve heard was 16, only sick for 8 months, responded quickly, stopped treatment after 6 months and has stayed well, as far as I know. And even if the drugs are for good, they are very clean drugs. HIV infected people have gotten very good research into their disease.
The literature suggests that the search for a sensitive enough reverse transcriptase assay was abandoned for HIV, as specific testing became highly sensitive. However, if you were looking for generic replication competent retroviruses that you could monitor, a clinically useful RT assay would seem to be indispensable. RT assays have been used in the lab since the late ’60’s, but seem to have been abandoned more recently, except for research purposes involving monitoring of retroviral vectors. Maybe one of the scientists reading can explain why this test isn’t clinically available? Why wouldn’t it be useful for MS, for example, given the suggestions of the papers above concerning that disease? Maybe some money to be made here, for any diagnostic test patent seekers who might be reading.

There was a recent paper showing that amprenavir inhibits XMRV in vitro (Li/Wlodawer on the side bar), but also, there are several clues in the literature that suggest that it might inhibit MLV proteases more broadly. HIV treatment wasn’t truly effective until PI’s were added. The first time I tried Lexiva, as a fourth drug then, still using an HIV model of HAART, it had the unexpected effect of CNS activation and it is doing that again. I describe it as “turning up the volume”, a perceptual shift. I am more reactive, but that is dying down now. It doesn’t do this with AIDS patients and I have no explanation, other than it moves the disease in some way, since I don’t see how it is an adverse effect of the drug. The other arv’s shook things up for me for a while too, but that felt like an inflammatory flare of usual symptoms. Physically, I think I feel a bit better, stronger in the last few days, but it could well be the swing of the pendulum. I will stay the course and report.
Dr. Deckoff-Jones,
I’m writing to you in the hope that by sharing a little of my medical history I can help. If XMRV is totally out of the picture it must in my case be a related retro-virus. I think if there were a place to pool ME/CFS patient information there might be something made obvious through comparative analysis.
I started on AZT about a year and a half ago On 3/6/10, my health seemed to gradually improve, by december I developed pain on the inside of both legs so at the end of december I stopped taking AZT. I declined rapidly and by the first of February I was worse than before I started on AZT. A few days into February I started taking Viread and Isentress and felt even worse for the next 10 days to two weeks (which I had read to expect this) I actually kept busy just to take my mind off how bad I felt.
Gradually I started to feel better and by the end of May of this year I thought I was well on my way to a normal existence. I think it was July and September I declined. Today I am definitely better than when I started but still far from my goal. I don’t want to stop taking anti-retrovirals.
I’m wondering if I would have done better if I had included Emtricitabine and if I should start now. I will discuss it with my doctor. If a yet unknown retrovirus is the culprit, it’s anybody’s guess as to which drugs are most effective.
I think the best course of action would be to find the cohort who have responded to the three above mentioned drugs and divide them into groups to see how they respond to other (additional) anti-retrovirals.
I think everyone affected would be perfectly okay with finding the treatment before finding the cause. Even if it’s a small subset of patients, we will have chipped away a little at this stumbling block we call ME/CFS.
I have had this for 18 and 1/2 years and I’m about to turn 64. So like everyone else I want answers now.
Sick patients trying to figure it out on their own, the ultimate failure of an ineffectual system. Scientists not only don’t talk to patients or doctors, they don’t even talk to each other, since somebody might steal their ideas. All closeted, each guy alone in a lab looking at a little piece of the elephant, writing in notebooks with pens?!! No copies? It seems even more dysfunctional than our broken medical system, that a dispute between a scientist and their employer can result in the hopes of an entire patient community being dashed on the shoals of intellectual property law and the criminal justice system.
I would like to thank Dr. Lipkin for being the voice of reason in an insane situation. He is positioned to help us. I hope he stays interested in our plight. We have very few friends, but maybe one new one who has the wherewithall to crack the case.
I maintain a confidential elist for patients taking antiretrovirals. Anyone reading who is taking arv’s and who would like to be signed up, please contact me: jdeckoffjones@gmail.com
