Autism, Allergies and Summertime Raging in 2016

  

This time of year many parents in the northern hemisphere are looking up “autism and allergy” on Google and more than 20,000 have ended up at my post from 2013 on this subject.

Not just for Stomach Health

It is clear that many people have noticed that allergy makes autism worse, even if your family doctor might think you are imagining it.

This year, thanks to our reader Alli from Switzerland, there is a new innovation in my therapy for Monty, now aged 13 with ASD.  Now we are firm believers in a specific probiotic bacteria to dampen the immune system (more IL-10, less IL-6 and likely more regulatory T cells) and minimize the development of pollen allergy and all its consequences.

There is a wide range of H1 antihistamines, mast cell stabilizers and inhaled steroids available and many readers of this blog are using a combination of some or all of these to control allergy and mast cell activation.

By using the Bio Gaia probiotic bacteria the magnitude of the allergic response to allergens is substantially reduced, so whatever problems allergy worsens in your specific subtype of autism, these should become much milder.

In our case the allergy will trigger summertime raging and loss of cognitive function.

The use of the calcium channel blocker Verapamil very effectively halts/prevents the raging, but it does not reduce the other effects of the allergy or the loss of cognitive function.

The use of the Bio Gaia probiotic reduces the problem at source; it greatly reduces the allergy itself.  Less allergy equals less summertime raging and equals less loss of cognitive function.

So for anyone filling up on antihistamines, steroids and mast cell stabilizers it could be well worth reading up on the studies on probiotics and allergy, or just make a two day trial with Bio Gaia.

Prior to Bio Gaia, we used Allergodil (Azelastine mast cell stabilizer and antihistamine) nasal spray or the more potent Dymista (Azelastine plus Fluticasone) nasal spray, plus oral H1 antihistamine (Claritin or Xyzal) and sometimes quercetin.  Verapamil was introduced to halt the raging/SIB caused by the allergy, which it does within minutes or can be given preventatively.

Each year the pollen allergy got worse than the previous year, starting five years ago at almost imperceptible and ending up with blood red sides of his nose.  With Bio Gaia there is just a faint pinkness at the side of his nose.

There are additional positive effects of Bio Gaia beyond the allergy reduction, but they do seem to vary from person to person.  In our case there is an increase in hugging and singing.  The research on this bacteria does show it increases the hormone oxytocin in mice.

A single species of gut bacteria can reverse autism-related social behavior in mice

In some people without obvious allergy, Bio Gaia’s effect on the immune system can also be quite dramatic.  In some people the standard dose is effective, but in others a much higher dose is needed.  The good thing is that the effect is visible very quickly and does seem to be maintained.  The main post on Bio Gaia is here.  

Bio Gaia is based on serious science but is available over the counter.

Ongoing Clinical Trial of Vivomixx Probiotic in Children with Autism

Since there is now interest in the potential benefit of probiotic bacteria to treat some autism, I wanted to point out that there actually is a clinical trial underway in Italy.  It is funded the Italian Ministry of Health and by the Tuscany Region.  They use Vivomixx, an OTC probiotic from the Italian speaking region of Switzerland.   

Vivomixx contains:

Streptococcus thermophilus DSM 24731, bifidobacteria (B. breve DSM 24732, B. longum DSM 24736, B. infantis DSM 24737) 
lactobacilli (L. acidophilus DSM 24735, L. plantarum DSM 24730, L. paracaseiDSM 24733, L. delbrueckii subsp. bulgaricus DSM 24734).

Before you start wondering, it is not cheap; the Swiss do not do cheap.

There is a detailed explanation of the trial in the full version of the paper below.  It is due to be completed at the end of 2017.

  
Vivomixx is virtually identical to a well known expensive probiotic called VCL#3, which has been used in research.  Due to some dispute the originator of VCL#3 started a new company which now sells Vivomixx.  In some countries one is available and in other countries it is the other one.  VCL#3 is even more expensive. 

Gut to brain interaction in Autism Spectrum Disorders: a randomized controlled trial on the role of probiotics on clinical, biochemical and neurophysiological parameters

Background

A high prevalence of a variety of gastrointestinal (GI) symptoms is frequently reported in patients with Autism Spectrum Disorders (ASD). The GI disturbances in ASD might be linked to gut dysbiosis representing the observable phenotype of a “gut-brain axis” disruption. The exploitation of strategies which can restore normal gut microbiota and reduce the gut production and absorption of toxins, such as probiotics addition/supplementation in a diet, may represent a non-pharmacological option in the treatment of GI disturbances in ASD. The aim of this randomized controlled trial is to determine the effects of supplementation with a probiotic mixture (Vivomixx®) in ASD children not only on specific GI symptoms, but also on the core deficits of the disorder, on cognitive and language development, and on brain function and connectivity. An ancillary aim is to evaluate possible effects of probiotic supplementation on urinary concentrations of phthalates (chemical pollutants) which have been previously linked to ASD.

Methods

A group of 100 preschoolers with ASD will be classified as belonging to a GI group or to a Non-GI (NGI) group on the basis of a symptom severity index specific to GI disorders. In order to obtain four arms, subjects belonging to the two groups (GI and NGI) will be blind randomized 1:1 to regular diet with probiotics or with placebo for 6 months. All participants will be assessed at baseline, after three months and after six months from baseline in order to evaluate the possible changes in: (1) GI symptoms; (2) autism symptoms severity; (3) affective and behavioral comorbid symptoms; (4) plasmatic, urinary and fecal biomarkers related to abnormal intestinal function; (5) neurophysiological patterns.

Discussion

The effects of treatments with probiotics on children with ASD need to be evaluated through rigorous controlled trials. Examining the impact of probiotics not only on clinical but also on neurophysiological patterns, the current trial sets out to provide new insights into the gut-brain connection in ASD patients. Moreover, results could add information to the relationship between phthalates levels, clinical features and neurophysiological patterns in ASD.

Trial registration

ClinicalTrials.gov Identifier: NCT02708901. Retrospectively registered: March 4, 2016.

So in the coming years it looks like there will be some actual data with which you can decide whether or not to trial specific probiotic bacteria. 

Hopefully, the Biogaia people in Sweden will provide their products for some independent researchers to trial on humans with autism, probably Swedish ones.

Biogaia Trial for Inflammatory Autism Subtypes

UPDATE: A significant minority of parents report negative reaction to Bio Gaia, this seems to relate to histamine; but more than 50% report very positive effects without any side effects; so best to try a very small dose initially to see if it is not well tolerated. 

Histamine Reaction to Bio Gaia gastrus

Alli, our reader from Switzerland, has established that a large daily dose (5 tablets a day, cycled 3 weeks on and 3 weeks off) of the Biogaia Gastrus probiotic has a positive effect on the inflammatory sub-type of her son’s autism and also in other people she has shared her therapy with.  There is plenty of science to support its use.

In earlier posts I looked at a different probiotic bacteria (Clostridium butyricum Miyairi 588) that is widely used in animals to improve auto-immune health.  That bacteria is used in humans, but as is the case with BioGaia Gastrus, the focus is on stomach health not auto immunity.  Nobody has proposed an effective dose of Miyairi 588 in human autism; I have only used it in small doses.

It turns out that there is vast wealth of research into the effects of specific probiotic bacteria.  The research is really very interesting for anyone with any kind of allergy.  I expect that, as Alli found, the potential therapeutic benefit goes far wider, to many kinds of inflammatory disease outside the gut, particularly the very hard to treat ones, perhaps even MS (multiple sclerosis).

Biogaia and Lactobacillus Reuteri 

Lactobacillus reuteri is a species of bacteria that belongs to one of the major lactic-acid producing genera of bacteria. It can be found in the human intestinal tract, though not always and often in relatively low numbers. Lactobacillus reuteri is also found in the gut of other mammals and birds.

Initially, Lactobacillus reuteri was used to treat necrotizing colitis, a gastrointestinal disease characterized by infection and inflammation that is particularly dangerous for infants, particularly those born prematurely. Lactobacillus reuteri was used due to its anti-inflammatory effects.

The research on Lactobacillus reuteri and necrotizing colitis used the Lactobacillus reuteri strains ATCC 55730 and its daughter strain DSM 17938, both of which can survive oral supplementation.

Interest in Lactobacillus reuteri grew after research confirmed that changing aspects of the digestive system can influence the immune system. A strain of Lactobacillus reuteri called ATCC PTA 6475 has been found to improve levels of testosterone and oxytocin, as well as skin quality in animal studies. Research on animals has also found potential benefits for hair quality, bone mass and preventing weight gain from obesity-causing diets.

One of the ways Lactobacillus reuteri may work involves a kind of T cell called a Treg cell (a T cell that down-regulates the immune system in part by producing a cytokine called IL-10). Lactobacillus reuteri increases the amount of Treg cells in the body, which suppresses the actions of another kind of T cell called a Th17 cell (which secretes IL-17). Preserving or reversing this process (either by increasing IL-10 or by blocking IL-17) appears to provide therapeutic benefits.

Lactobacillus reuteri increases the number of Treg cells in the intestines, which can then be absorbed back into the blood to benefit the rest of the body.

BioGaia Gastrus is a combination of the well-researched probiotic strain Lactobacillus reuteri17938 (Lactobacillus reuteri Protectis) and the anti-inflammatory strain Lactobacillus reuteri ATCC PTA 6475. It contains 200 million CFU of live bacteria.

The original Biogaia product is called BioGaia Protectis; it only contains Lactobacillus reuteri 17938 (Lactobacillus reuteri Protectis).  It contains 100 million CFU of live bacteria.

Since some readers are already trialing Alli’s therapy, I thought it would be useful to have a single place on this blog where people could leave feedback.  Here is her explanation:-

Dear all,

Lactobacillus Reuteri ATCC 55730 was initially discovered and sourced from women from Peru who carried this strain in their breast milk. 

"The first strain of Lactobacillus reuteri for human use was isolated in 1990 from the breast milk of a Peruvian mother living in the Andes. This strain was deposited at the American Type Culture Collection (ATCC) as Lactobacillus reuteri SD 2112 (SD = safety deposit), and was later given the number ATCC 55730.

In 2007 Lactobacillus reuteri ATCC 55730 was replaced by the “daughter strain” Lactobacillus reuteri DSM 17938. The only difference between the strains is the loss of two plasmids of ATCC 55730 that carried resistance to tetracycline and lincomycin, respectively."http://www.biogaia.com/history-lactobacillus-reuteri

Through my personal review of immunology literature and ASD/immunity related literature and documenting crossroads between immune pathways and Mtor pathways, I came to the conclusion more than one year ago that this was a very interesting strain to try on my son with ASD and a TH1 profile. Biogaia Gastrus was only available in Korea and Italy at the time so I ordered it from an Italian pharmacy online.
It has helped my son significantly in combination with other interventions.

The mechanism at stake is probably the following:

- downregulation of TH1 through upregulation of IL-10 and downregulation of IL-17
This prevents autoimmune phenomena and cytokine flares which affect cognition in certain subtypes of ASD. However, the downside is that long term intake also impairs one's immune system's capacity to fight off infections... 

We use Biogaia on and off for 3 week periods- at a dosage of 5 tablets a day (less is useless in terms of potency).

Use must be stopped if a child shoes any sign of infection.

I have shared this over the past year with several parents around me who have children with similar subtypes and they report similar results.

Effect of Lactobacillus reuteri 17938 on Monty

My son Monty, aged 12 with autism, pollen allergy and occasional asthma, was again my willing test subject.  This is the worst time of the year when his allergy triggers asthma and autism flare-ups.

Where we live, only the older version of Biogaia is sold.  So he has been taking Lactobacillus reuteri 17938, 400 million CFU a day.

In Alli’s dosage there is 500 million CFU of reuteri 17938 and 500 million of reuteri ATCC PTA 6475.

There was an effect almost immediately on his allergy; his nose changed colour.  His pollen allergy gets gradually worse in the summer and the sides of his nose becomes bright red.  Short term use of topical steroids reverses this, but the pollen season is four months long.

Along with his red nose, his behavior gets worse leading to aggression,SIB and cognitive decline.  This lasts from mid June to October.  The aggression and SIB responds very well to treatment with Verapamil, but this does not reverse the cognitive decline.  

My behavioural observations might be wishful thinking, but I cannot be imagining bright red fading to a mild pink.

Clearly even at my reduced dosage and lack of the second anti-inflammatory bacteria (L. reuteri ATCC PTA 6475) something very helpful is happening.

As is my habit, I did a quick review of the literature and found plenty of supporting evidence for the potential benefit of specific bacteria on allergy.

As Alli has found, the potential benefit goes far beyond allergy.

  

Oral treatment with live Lactobacillus reuteri inhibits the allergic airway response in mice

RESULTS:

Oral treatment with live Lactobacillus reuteri but not Lactobacillus salivarius significantly attenuated the influx of eosinophils to the airway lumen and parenchyma and reduced the levels of tumor necrosis factor, monocyte chemoattractant protein-1, IL-5, and IL-13 in bronchoalveolar lavage fluid of antigen-challenged animals, but there was no change in eotaxin or IL-10. L. reuteri but not L. salivarius also decreased allergen-induced airway hyperresponsiveness. These responses were dependent on Toll-like receptor 9 and were associated with increased activity of indoleamine 2,3-dioxygenase. Killed organisms did not mimic the ability of the live L. reuteri to attenuate inflammation or airway hyperresponsiveness.

CONCLUSION:

Oral treatment with live L. reuteri can attenuate major characteristics of an asthmatic response in a mouse model of allergic airway inflammation. These results suggest that oral treatment with specific live probiotic strains may have therapeutic potential in the treatment of allergic airway disease.

Reader Trials

It would be helpful if readers would share feedback on their use of high dose Biogaia probiotics.

There are many other types of probiotic, but it would be helpful to first focus on the one that has been shown by Alli to be effective.

It seems to me that within a week you are going to know if you have a responder.  As usual you need to see how the effect varies over time.  Numerous interventions seem to be effective and then fade away and some even go from positive to negative.  I will certainly be continuing to see the longer term effect and hopefully finally adding something new to my PolyPill.
