Eubiotics for GI Dysfunction and some Autism
Today’s post is about some drugs/supplements that have already been discussed in earlier posts. Rifaximin, used in cycles, is an effective part of our reader Maja’s therapy, while Sodium Butyrate was highlighted long ago by our reader in Switzerland, Alli.
I had a consultation with a gastroenterologist last week and came away with a prescription for Rifaximin, microencapsulated Sodium Butyrate and Lactobacillus Plantarum 299v. Where we live, these are all inexpensive. Rifaximin is an antibiotic with extra benefits and costs about 7 euros (9 dollars).
A course of Rifaximin can cost $2,000 in the United States.
I was pleased to read that the private equity owners of a pharmaceutical company that raised the price of a common thyroid drug by 6000% have just been fined $140 million in the UK.

Perhaps some of our US readers should query the crazy price of drugs in the US with their congressman? Very many cheap old drugs are ultra expensive in the US, even insulin is over-priced. Not a good model of a market economy.
Eubiotics – a big business
You may very well never have come across the term eubiotic before, but it is already a multi-billion dollar business. A eubiotic is something that changes the gut microbiome to improve health. The big business to date are additives to animal feed, rather than products for human health.
Eubiotics work for humans as well. Rifaximin is an antibiotic but it also has the additional properties of a eubiotic.
“These include: modulation of the microflora of the gastrointestinal tract by promoting the growth of Lactobacilli and Bifidobacteria strains (the so-called “eubiotic” effect) as well as modulation of bacterial metabolism, including inhibition of the hydrocarbon-derived pathways. This drug is also capable of reducing the virulence of enteropathogenic Escherichia coli strains by inhibiting the expression of enterotoxins or adhesive factors. Interestingly, Rifaximin is distinguished by several anti-inflammatory activities mainly exerted by the pregnane X receptor (PXR), expressed primarily in the gastrointestinal tract, the small intestine, and the colon. Due to the activity described above, Rifaximin is called a eubiotic, not an antibiotic.”

Rifaximin, like vancomycin, is usually thought of as a GI antibiotic; it stays in your gut and almost none ends up in your blood. Both drugs are used to kill off bacteria in your gut. This is all vancomycin does, so it is not classed as a eubiotic. Rifaximin, however, goes on to perform further functions as a eubiotic, so it models your gut flora in a beneficial way.
Rifaximin is almost a wonder drug for IBS-D (irritable bowel syndrome with diarrhea). It is also a common therapy for SIBO (small intestinal bacterial overgrowth), but while it works well for some, it actually makes things worse for some others.
Rifaximin is used both as a therapy for an acute GI problem and preventatively. It can be used in cycles, like a few days every month.
Maja is in a good position, because where she lives Rifaximin costs a few euros/dollars.
People with IBS-D in the United States often cannot afford monthly cycles of Rifaximin.
Other kinds of eubiotics include prebiotics, other probiotics, all kinds of clever fiber, inulin, fructooligosaccharides (FOS), galactooligosaccharides (GOS) etc. I did cover psychobiotics in an earlier post, these are probiotic bacteria that are used to reduce anxiety, ADHD and other psychiatric symptoms.

Sodium Butyrate
Sodium buyrate produces butyric acid when you swallow it. Butyric acid is what gives rancid butter its smell. Butyric acid is one of the big eubiotics used in the animal feed industry. I did cover the very old Japanese probiotic MIYAIRI 588 (full name is Clostridium butyricum MIYAIRI 588) a long time ago in this blog. This probiotic, in use since the Second World War, produces butyric acid in your gut by fermentation. In Japan this probiotic is used in humans and more recently as an additive to animal feed, to produce healthier, bigger, chickens and pigs.
Our reader MG in Hong Kong recently reported that MIYAIRI 588 was beneficial in his case.
My gastroenterologist prescribed me Microencapsulated Sodium Butyrate, which is covered in the research and has encouraging results. When you see the word microencapsulated, you might start feeling some pain developing in your wallet, rather than in your gut, but again, this product called Integra and made in Poland, was not so pricey - about EUR 10 ($12) for 60 capsules. One capsule contains 150 mg of sodium butyrate in tiny particles covered in triglycerides. I have no idea if it is going to do me any good, but the research suggests it is beneficial for certain types of GI dysfunction and will strengthen the intestinal gut barrier (the equivalent of the blood brain barrier).
Butyric acid has several different modes of action, one is as an HDAC inhibitor, which was covered in earlier posts. HDAC inhibitors can change gene transcription, which is potentially very useful, including in the prevention and treatment of some cancers. The potent HDAC inhibitors from cancer therapy show effect in some types of single gene autism.

There are different classes of HDAC inhibitor and you would need to match the type of autism with the appropriate type of HDAC inhibitor. Valproic acid is another common HDAC inhibitor sitting on the shelf of many people with autism plus epilepsy.
Lactobacillus Plantarum 299v
Lactobacillus plantarum 299v has been shown to improve symptoms of IBS (Irritable Bowel Syndrome). It prevents Clostridium difficile-associated diarrhea among patients receiving antibiotic treatment. It is also known to be immunomodulatory, shifting the balance away from pro-inflammatory cytokines.
The role of Lactobacillus plantarum 299v in supporting treatment of selected diseases
Alterations in composition of human gut microbiome can lead to its dysbiosis. It is associated with gastrointestinal side effects during anti-cancer treatment, antibiotics administration, or infectious agents. There are studies confirming positive effect of consuming Lactobacillus plantarum 299v on intestinal microflora. This review summarizes the current knowledge about the role of L. plantarum 299v in supporting treatment of selected diseases, such as cancer, irritable bowel syndrome (IBS), and Clostridium difficile infection. The immunomodulating properties of L. plantarum 299v include an increase in the level of anti-inflammatory cytokines,which reduce the risk of cancer and improve the efficacy of regimens. The intake of L. plantarum 299v provides benefits for IBS patients, mainly due to normalization of stool and relief of abdominal pain, which significantly improves the quality of life of IBS patients. In addition, the intake of L. plantarum 299v prevents C. difficile-associated diarrhea among patients receiving antibiotic treatment. Due to the limited possibilities of treating these diseases and numerous complications of cancer treatment, there is a need for new therapeutic strategies. The administration of L. plantarum 299v seems to be useful in these cases.
Might a daily dose of friendly bacteria help treat autism? UK researchers hope probiotics will soothe the gut problems linked to autism and may even ease psychological symptoms. They are planning a clinical trial to test the idea.
The proposed health benefits of probiotic bacteria are well known. The beneficial bugs are thought to out-compete other gut bacteria that can cause diarrhoea and ill health.
Children with autism are known to have higher levels of one group of 'bad' bacteria, Clostridia, in their guts, explains Glenn Gibson from the University of Reading. So he hopes probiotic food supplements that lower levels of Clostridia will allay some symptoms of autism.
He is not suggesting that the bad bacteria cause autism: genetic and environmental factors are both likely to contribute to the complex disorder, the cause of which is unknown. But toxic by-products of the bacteria may be absorbed into the blood and travel to the brain, where they may play a role in ill health.
At present, the researchers are honing their choice of bacteria. There are many different types of good bacteria, so it is important to choose one that can compete effectively against Clostridia.
One candidate, called Lactobacillus plantarum 299v, looks especially promising. The bacterium binds to the gut lining and stimulates its growth. As well as out-competing other bacteria, it also lowers gut pH, which helps the digestive tract to fight infection. It stays in the gut for days and has never been associated with any health problems.
Conclusion
I am always surprised how many common drugs that you come across have potential to be repurposed to benefit some people with autism.
It really shows how effective therapy, for at least some people with autism, is already in the medicine cabinet at home, or more likely over at the grandparents’ house.
(statins, calcium channel blockers, asthma/COPD drugs, other blood pressure drugs, diuretics, type 2 diabetes drugs)
I thought my gastroenterologist’s therapy was quite enlightened. I hope his diagnosis is accurate; I am not entirely convinced, but time will tell. The diagnosis from doctor number one was kidney stones and now I am on doctor number three. An accurate diagnosis is not always a simple matter, as autism parents know only too well.
I did meet Dr Federico Balzola a while back. He is an Italian gastroenterologist with a keen interest in autism. He is an associate of Dr Arthur Krigsman, a US gastroenterologist heavily involved with autistic patients. In some countries the connection between GI problems and autism is still a taboo subject, seemingly because Dr Andrew Wakefield was a gastroenterologist.
I am always surprised how many young Aspies have symptoms of IBS or IBD. I would actually like to know if this is mainly a problem in childhood and adolescence, which I suspect is the case.
One of my most popular posts was another one about gastroenterology, which really surprised me.
