Anyone rushing out to buy Doxy should know that there is little correlation between mouse and human studies. It seems to me way too early to experiment with this treatment, but hey, if anybody does, let me know how it works out.

Agree. From nature.com/articles/srep41755

" doxycycline, an antibiotic belonging to the family of tetracyclines, has been reported to exhibit neuroprotective activity in both MPTP and 6-OHDA animal models of PD. "

A remarkable variety of things are neuroprotective in such models. These models are woefully inadequate to predict real Parkinson's patients' responses because they assess nerve protection from artificially induced Parkinsonism rather than recovery from actual Parkinson's.

The 6-OHDA rat model is created by, essentially, injecting hydrogen peroxide into their brain. Far as I know, dopaminergic neurons don't die from hydrogen peroxide in PWP.

This article sends mixed messages. It details the 4 good reasons, but then at the end it says "Much still needs to be done to make doxycycline an effective treatment for PD".

Farooqji in reply toFarooqji

it says:

"DOX is clearly promising for preventing and inhibiting

dopaminergic cell loss (Sapadin and Fleischmajer 2006)

through its anti-inflammatory effects (Joshi and Miller

1997). Importantly, the long-term administration (up to

2 years) of subantimicrobial doses of DOX has not produced

antibiotic side effects in clinical trials (Golub et al.

2016; Keijmel et al. 2017). Thus, subantimicrobial doses

of DOX may represent a game changer in PD therapy that

will benefit a considerable number of patients."

MBAnderson in reply toFarooqji

Impressive study. 1 of the side effects they listed was gastrointestinal, but indicated it was minor. I wonder if long-term use has an adverse effects on the micro-biome and/or cause strains of bacteria to mutate and become more drug-resistant?

I don't understand why she says 100mg/day. The research paper says "... clinical trials have demonstrated that the administration of subantibiotic doses (20–40 mg/day) does not alter bacterial susceptibility to antibiotics and results in anti-inflammatory effects ..."

Thanks for this issue Jim. Simon rarely takes a position.

MBAnderson profile image
MBAnderson in reply tojimcaster

Jim,

I should clarify. In my 1st comment to your post, I said Simon rarely takes a position (perhaps incorrectly) hoping to underscore the significance that in this blog, he took a clear, emphatic position - against DOX for PD.

LAJ12345 said her husband took DOX for several years and through analysis they concluded that it compromised his microbiome, after which he was diagnosed with PD. She speculates that his compromised biome might have caused his PD.

That's not remotely unreasonable speculation. One of the papers iqbaliqbal shared with us conclude that the effect DOX has on bacterial resistance varies by individual. What that means, therefore, is that it is possible that taking DOX for PD may worsen the PD in some people.

As I am unaware of an occasion where anyone has shown Simon to have been wrong, so if he says we shouldn't take to DOX for PD, that's good enough for me.

Simon says, when Prof Tulken says, "…using antibiotics at sub-therapeutic doses is the best way to trigger the emergence of resistance (supported by many in vitro and in vivo studies.)" "he is correct."

... Long term use (which Parkinson’s disease would probably require) of an antibiotic at sub-therapeutic levels will only encourage the rise of antibiotic resistant bacteria possibly within individuals.

Simon says the professor is correct again when he says, "If doxycycline really acts as the authors propose, the molecular targets are probably very different from those causing antibacterial activity. it should therefore be possible to dissociate these effect from the antibacterial effects and to get active compounds devoid of antibacterial activity This is where research must go to rather than in trying to use doxycycline itself.”

Simon concludes with, "Rather than tempting disaster, we need to take the more prudent approach."

" My personal position hasn't changed: using antibiotics at sub-therapeutic doses is the best way to trigger the emergence of resistance. 80% of us wouldn't be here if not for antibiotics. Our main line of defense & yet we are so reckless with them. Sorry for the rant"

And subsequently received another message as below

Rhyothemis in reply tojimcaster

I find the antibiotic resistance angle a bit odd, since Oracea is already out there and used by thousands of people for ocular rosacea. I'd use it if I could afford it. Also, it is a common aquarium antibiotic. So it is already all over the place.

As for gut microbiome concerns, that's a bit more of an open question. Low doses aren't supposed to affect the microbiome, but who knows. Green tea is antibacterial and affects the microbiome; epidemiological studies show green tea to be on balance beneficial for overall health - but no association, positive or negative, with PD risk, even though EGCG reduces a-syn aggregation. OTOH black tea consumption is associated with lower risk, independent of caffeine. {shrug}

I would echo the comments about PWP not being mice, and the vast trail of "promising in vitro and vivo" which fail to demonstrate efficacy. To that I would add the general caution that mainstream repurposing trials haven't picked this up, it hasn't been trialled, the effects described are due to the drug not its anti-microbial action and imply perpetual use (for how long? - forever). Apart from the consequences for the microbiome , there is a growing first world move to reduce the use of antibiotics due to the (potentially catastrophic) public health issues of resistant bacteria strains, of which MRSA is the tip of the iceberg.

I'm still interested to hear more, but I can't imagine responsible physicians prescribing long term DOX for PD without authorisation - which is going to require clinical trials. And I can imagine objections to trials with the purpose of long term broad spectrum systemic antibiotic use, given the issues about resistant strains of bacteria. Obviously, if it IS therapeutically effective in PWP then the safety issues regarding antibiotic abuse would need to be balanced.

MBAnderson profile image
MBAnderson in reply toWinnieThePoo

Poo,

You've touched on some of the important issues which were not really addressed by the study. My threshold for permanently taking a broad spectrum antibiotic is about 10 times higher than it is for starting a new supplement.

Hopefully, someone can explain how you can take an antibiotic long-term and not expect other complications?

park_bear profile image
park_bear in reply toMBAnderson

Long-term antibiotics deplete not only gut bacteria but also the skin biome, setting a person up for fungal infections.

MBAnderson profile image
MBAnderson in reply topark_bear

I just read an abstract that concluded people who eat meat that has been fed antibiotics have traces in their poop and from DNA and RNA sequencing, the study concludes that even trace amounts altered the micro-biome.

I had an appointment with a G.I. specialist 2 weeks ago at the VA, we had a good discussion, but one thing she said, "Try not to take antibiotics. They can impact your microbiota for up to a year."

jimcaster profile image
jimcaster in reply toMBAnderson

What if, as noted, we could take 20-40 mg per day and got the anti inflammatory benefits without the antibiotic risk? What if we only took it for a few weeks? I'm reminded of the post by Ronshere a few days ago with this story

omicsonline.org/open-access...

jimcaster profile image
jimcaster in reply tojimcaster

I should add that I'm not "sold", but wouldn't it be something if we could take a simple antibiotic in low doses for a few weeks and get better? I wish there was more follow up research on this...

WinnieThePoo profile image
WinnieThePoo in reply tojimcaster

Even just scanning the research shows that the intended PD therapy would be long term continuous permanent administration. Not take it for a few weeks. Globally that could lead to the end of all surgery as we currently know it, as operations become at risk of new resistant forms of bacteria for which we no longer have any effective antibiotic response. That's why simple trials for talking the basic antibiotic as a long term cure for a chronic illness will meet resistance.

MBAnderson profile image
MBAnderson in reply tojimcaster

Jim,

I agree, if the "what-ifs" were true, I'd be interested.

In the anecdote you provided, the authors didn't say how long it'd been between the administration of antibiotics and their declaration that the symptoms hadn't returned, "to this day." Could've been a couple weeks or couple months. Could be that by now, the PD returned with a vengeance -- along with additional complications.

I'm probably more spooked by antibiotics than most people. I'd need to see a successful phase II study and even then, the outcome would have to be dramatic.

I'd need Hikoi's standard of proof before I inject myself with antibiotics.

jimcaster profile image
jimcaster in reply toMBAnderson

This doesn't change anything, but it appears that the article was written in 2018 and the patient took antibiotics for four weeks in 2009.

MBAnderson profile image
MBAnderson in reply tojimcaster

Jim, good find. It doesn't change anything for me. I wouldn't expect a compromised micro-biome to generate much trouble in 4 weeks. The question is whether or not the microbial action of a long-term, 40 mg/day dose of an antibiotic no longer affects bacteria. I don't know, but if I had to guess, I'd say it is.

If your PD is caused by a bacterial infection and you found a doctor who can know that with certainty, and this doctor has a theory as to what antibiotic to use, the dose and strength, but is wrong, might that cause the Parkinson’s disease causing bacteria to become more virulent?

How does one's doctor know that their PD is caused by an infection?

jimcaster profile image
jimcaster in reply toMBAnderson

I agree. Given the rate of misdiagnosis, it's also quite possible that the patient had something other than Parkinson's disease. This is all intriguing and I hope there are more follow up studies, but I'm staying away from antibiotics unless the evidence becomes overwhelming.

MBAnderson profile image
MBAnderson in reply tojimcaster

I see now. The claim is that it's PD did not come back 9 years later. Thank you for pointing this out. It does render moot my point about 4 weeks.

Interesting! The doctor put me on doxycycline for 6 months after double pneumonia (resulting in bronchiectasis). I was left with loss of taste AND I developed a rash over the top half of my body, not realizing until now that the rash was probably because of the doxy. Thanks for posting this park_bear.

I was able to open the eddrugsearch link. Doxy is hard to get from doctors. Used to treat Lyme Disease and if more than 21 days of this drug is needed many doctors are reluctant to prescribe/renew drug. People with chronic Lyme Disease are forced to turn to integrative doctors (not covered by any insurance) and pay out-of-pocket for the doctor visits and sometimes the RX (depending on your insurance provider).

Rhyothemis profile image
Rhyothemis in reply toLindaP50

It's no hard to get from doctors - it is standard treatment for ocular rosacea. I'm not on it because the time-release low dose (40mg) version (Oracea) that is best and currently on-patent (and what my eye doctor wants me to take) would cost me ~ $230month (high deductible plan; that price is with a coupon, good for how many months IDK, without coupon it is over $500).

As far as antibiotic resistance goes - pfft - I've thought about using fish doxycycline since it is an order of magnitude cheaper, but am not willing to take the risk. There's lots of aquarium water full of doxy that goes down the drain - I think the 'containing resistance threat' ship sailed a long time ago for doxy.

My husband had been taking 100mg daily doxy for years for rosacea and acne well before PD diagnosis. About 6 months ago he had a faecal test done under a natural doctor and his gut bacteria are very strange. No bifido bacteria, and the ratio of aerobes to anaerobes is very abnormal, and he has a large amount of a bacteria called corynebacterium amylatum and other oral bacteria which we assume is due to the long term effect of taking doxy wiping out some of the beneficial bacteria but not others which are resistant to it. He has stopped taking it since and was taking berberine and allicin alternate weeks with probiotics for a few months and his acne seemed to be fairly well controlled but has taken a break from that for a month as his anxiety levels have been bad and so we have cut back treatments to the bare minimum as the constant capsule taking was stressing him out. With Christmas he has been having a bit more of foods like Christmas cake, meat, cheese and more fruits etc whereas we had changed our diet to sugar and gluten free, very little meat, or dairy.

The acne has now come back quite badly so he is back on the berberine allicin / probiotic regime again. Nothing so far seems to be able cure the acne but these herbals alongside a strict sugar and junk food free diet seem to keep it down a bit.

I wouldn’t say taking the doxy has helped his PD symptoms as he started on it well before diagnosis and before most of his symptoms. We think the unbalanced gut bacteria could have brought it on.

Very informative, are his PD symptoms better on the sugar and gluten free diet?

LAJ12345 profile image
LAJ12345 in reply toConnieD

It is so hard to say as stress seems to be the thing that makes the difference to symptoms way more than anything else. His skin was definitely better and he lost 10kg in about 6-8 weeks which was needed as he was over weight. His whole big belly went down. But it is really hard to say what has helped as he has been on b1 and other vitamins too, mannose on and off. Sinemet makes no difference but he doesn’t really have a tremor anyway. Christmas, school hold with the kids home, and going away have stressed him to the max, and now we are back home he is stressing about jobs that need doing and being “useless” in his words.

LAJ12345 profile image
LAJ12345 in reply toJAS9

Yes, he has had green tea which also contributed to the rapid weight loss I think, then he was on the restore gold which also has it for a while but he was feeling ill from stress so cut back on all the supplements as it was stressing him having to take them.

He stopped the green tea originally as he was having pains in his abdomen which seemed to be around his liver and I read it can cause liver failure in some people so he stopped it just in case. Liver function was normal. The weight loss every time he starts it again is dramatic so don’t want him to lose too much more because of cause he thinks he is fading away and that also stresses him. Actually I think he looks a lot more healthy now at his current weight but he is in a negative frame of mind.

Have you thought about this...doxy is an antibiotic used to treat Lyme. If doxy supposedly helps Parkinson’s, then think about this......the theory is that Lyme and coinfections are attacking the brain, therefore causing Parkinson symptoms.

Look

Into the gut brain connection...

You have to be careful with antibiotics though, as they destroy good bacteria.

You must supplement with good live probiotics.

Even better, treat it naturally.

If you have rosacea, you can easily get an ongoing Rx for Doxy. I took it on/off for a few years. The last time I tried it, I felt it made my PD symptoms worse. It can affect balance via lightheadedness, so maybe I was just experiencing a side effect, not worsening of symptoms? I just watched the documentary on Lyme on Amazon Prime....super scary! I know 2 people that were sick for years with Lyme before proper diagnosis and treatment. Thank god for Doxy!

Preclinical studies are merely suggestive - very weak evidence. The few anecdotal reports in the foregoing comments, from actual humans with Parkinson's, are better evidence. Conclusion: do not try this at home.

The article headline was grossly inappropriate.

Also, there have been prior occasions where antibiotics were thought to be "anti-inflammatory", but that turned out to be merely because they killed or suppressed bacteria causing inflammation.

There are supposed to be thousands of different types of bacteria in a healthy gut. Probiotics can't possibly be good enough to repair any significant amount of damage. Anyone risking this is playing with something very fragile and easily thrown out of balance.
