there as quite a story there dcd.
basically, i was researching some interesting biology in the gut that i got into after reading a paper that found that mammals can develop and acquired Intestinal Alkaline Phosphatase (IAP) deficiency after repeated exposure to food borne pathogens - even subclinical exposures - eg mild food poisoning or "Delhi belly".
this is very intriguing as IAP has many important functions in the gut to do with regulation of the environment there, permeability of the intestinal membrane and regulation of endotoxins from commensal bacteria.
IAP regulates lipid absorption across the apical membrane of enterocytes, participates in the regulation of bicarbonate secretion and of duodenal surface pH, limits bacterial trans-epithelial passage, and finally
controls bacterial endotoxin-induced inflammation by dephosphorylation.
basically it is responsible for de-activating LPS endotoxins in the gut so they do not inflame the immune system. without it - or with a deficiency of it - the gut become hyper reactive to the normal gut bacteria living inside it..... sound familiar?
the mechanism the autors of teh paper found is that neuraminidases in the gut get chronically upregulated and this causes the IAP deficiency.
in theory if you could down regulate these again then the IAP would normalise.
it turns out there are quite a few known neuraminidase inhibitors - both in the pharmaceutical world ( many antiviral drugs work by inhibiting viral neuraminidases - viruses use them as part of their infection strategy) - but also many plant chemicals (herbs) have neuraminidase inhibiting actions ( probably to protect them from plant viruses).
my thoughts were that it might be interesting to trial some of these - perhaps herbs that could be taken orally - as a test to see if this mechanism might be at work.
i shortlisted the following herbs that are all documented to have neuraminidase inhibiting activity
i was familiar with most of them - and started out gradually - increasing the dose every few days to feel my way through effects
tincture / dose per 10ml measure (ml )
Chinese skullcap 2.5
Berberine (mahonia) 0.5
Elder leaf 2
Isatis 1.5
Licorice 1.5
Houttuynia 1.5
i got up to around 2x 10ml measures 3x a day and had an almighty flare
my best guess is the herbs killed off lots of gut bacteria and that caused a massive herx
i have since leaned i am super sensitive to berberine herbs - that could cause this reaction all on its own after only around 1ml of tincture a day - so i think it was mainly the Berberine herb that caused it. Houttuynia is also a pretty broad anti-microbial so could have been involved. i tolerate Licorice, skullcap, elder and isatis pretty well.
this was interesting as berberine pretty much all stays in the gut - so systemic reactions are rare - unless taking mega doses - which i was not.
my flare symptoms were - fever, chills, all over pain , rapid heartbeat, feeling very very ill ( basically had to lie in a darkened room for 2 days and took about
1 week to recover)
the CBC test during the herx like reaction recorded were taken a couple of days past the peak i think.
not much happened good or bad until i hit the level where i suddenly got very ill. it doesn't look like i could tolerate enough of the herbs to get useful effects before running into the fallout from the direct anti-microbial actions of the herbs i used. So as an experiment into trying to test the potential mechanism of IAP deficiency the experiment was not a great success.
however, i still believe there is something to the theory though. As i dug into it it became clear to me that such an IAP deficiency could well trigger a long term chronic state with many cascading downstream effects that would include or could be linked to many common chronic conditions :
SIBO,
dysbiosis
systemic inflammation
oxidative stress
fatigue
auto-immunity,
diseases like diabetes, skin conditions, arthritic conditions, IBD, osteoporosis
this is the original paper that initially triggered my interest
https://www.ncbi.nlm.nih.gov/pmc/articles/pmc5824721/there is quite a lot going on - and many of the downstream mechanisms themselves may well have self perpetuating loops - so its certainly possible to see how such a condition, once initiated, might become stuck..
here is a diagram that tries to capture the main mechanism and interconnectedness that i researched at that time:
https://ibb.co/7yjvflbi had intended to write a post on it with some of the references for further discussion - but i now think its similar to the SIBO discussion - in that something is going on there for sure - but if Lyme and Co's are the trigger in my case - it makes more sense to focus on those first and then see where i am after getting that under control
