Buy Arbaclofen for Autism? Perhaps try Pantogam Aktiv?


             
An Enantiomer is like a mirror image,
so there are two versions of the “same” molecule one called R- and one called  S-


Some people are still looking to obtain Arbaclofen to treat autism and Fragile-X, they regularly stumble upon this blog.

A couple of years ago there was a lot of interest in Arbaclofen (R-baclofen), a GABAB drug, which is, in effect, a special version of a cheap existing drug called Baclofen.  Baclofen is generally used to treat spasticity, but also alcoholism and even hiccups.

As we saw in earlier posts, the drug Baclofen is a mixture of R-Baclofen and S-Baclofen. The research showed that their action is different and that S-Baclofen reduced the effect of R-baclofen.  So in some modes of action, pure R-Baclofen would have much greater effect than the regular Baclofen mixture.

If you use the "index by subject" on this blog, which is a tab at the top, you can find the posts that relate to Arbaclofen.

Arbaclofen

Arbaclofen Research in Autism/Fragile X

This very expensive episode was triggered by one child with autism being prescribed regular Baclofen, for an unrelated issue.  That child’s autism had dramatically improved, this then led to the interest of Seaside Therapeutics, who already had another prospective autism drug.

After tens of millions of dollars spent, everything stopped a couple of years ago.  The developer, Seaside Therapeutics, appears to have been shut down, although in its clinical trial a substantial minority found the drug was effective.  The way the trial had been structured, the drug did not achieve is “primary endpoint” and so Roche, the potential follow-on investor, deemed the trial a failure.

This led to many unhappy parents seeking alternative sources of R-Baclofen, which they believed had been effective.


Baclofen for Asperger’s?

At least one regular reader of this blog finds that Baclofen is very helpful for himself.

Yesterday before completing this post I had some exchanges with a UK pediatrician (spelled paediatrician in the UK) who is prescribing Baclofen to eight children with Asperger’s to treat anxiety. The results are very positive.  I do wonder is this a 100% response rate,  or are the eight a subset of all the children that have tried the drug?

One of our Australian readers of this blog is very interested in minimizing anxiety in his child with high functioning autism.  He did forward me some research, a while back,  that links GABAB to Somatostatin, also called Growth Hormone Inhibiting Hormone (GHIH) .  The research from Carnegie Mellon shows that GHIH changes the way the brain functions. 
This does get very complicated the more you dig and, until today, I did not start to write up my findings.  This is just some initial thoughts/links for scientists.
“Furthermore, by silencing certain parts of the neuronal network, the activity of the somatostatin neurons also can change the way the brain functions, heightening some perceptual pathways and silencing others.” 

“If the levels of human growth hormone in circulation in the brain and the blood get too high, then special cells called somatostatin neurons detect this. These neurons then trigger the creation of more GHIH in the brain. This then in turn slows down the secretion of human growth hormone.”

 “Mature interneurons from this brain region mainly express either parvalbumin or somatostatin, which serve as markers of these subtypes. Parvalbumin neurons tend to fire quickly in response to signals, whereas the somatostatin ones respond more slowly.
In control mice, the ratio of these two subtypes is about 50:50. By contrast, the mutant mice show a dramatic decrease in the number of interneurons expressing somatostatin. This results in an excess of abnormally large cells expressing parvalbumin.
Despite an overall loss of interneurons, the mice have more inhibitory signals than controls do, skewing the signaling balance to excitation.” 

We do know that the various growth factors in people with autism can be disturbed, but in different types of autism that disturbance varies, just to complicate things.

Various therapies based on this are under development (one uses IGF-1 and NNZ-256 is another).  We also know that many people with classic autism have accelerated growth (both body and head) in the first two years.  We also know that brain growth is also accelerated.

We know from the genetic research that many of the anomalies relate to GABA.

We know that targeting the GABAA receptor can be hugely beneficial in classic autism (bumetanide and micro-dose clonazepam).  We can also fine tune the structure of the GABAA receptor and potentiate it using allosteric modulators (like Pregnenolone or progesterone).  This also gets very complicated.



Baclofen for Classic Autism?

Baclofen is a spasticity drug:

Spasticity (from Greek spasmos-, meaning "drawing, pulling") is a feature of altered skeletal muscle performance with a combination of paralysis, increased tendon reflex activity and hypertonia. It is also colloquially referred to as an unusual "tightness", stiffness, or "pull" of muscles.

People with (classic) autism as opposed to Asperger’s can have all sorts of fine and gross motor issues, particularly as young children.

They can “toe walk”, walk with their feet pointing in different directions, they can have “claw hand”.  They can struggle to control a pencil and even when they learn, their handwriting can be very sloppy.

Are these spasticity issues?  I think they probably are.

When people’s autism flares up, an early sign is worsening handwriting.

When my son’s Polypill begins to wear off in spring/summer at school at around 11 am, the claw hand returns.

I did indeed try Baclofen about a year ago.  There is an effect - no claw hand.

The problem with Baclofen is tolerance, the more you use it the higher the effective dose becomes, just like benzodiazepines.

So I noted that there was an effect, but chose to move on.


Meanwhile over in Russia

For many years in Russia they have had their own GABAB drug, similar to Baclofen, it is called Pantogam.  Pantogam has been used for years as a therapy for neurological conditions including autism.

Just as Baclofen is “racemic mixture” of left-baclofen and right-baclofen, so is Pantogam.  There is S-Pantogam and R-Pantogam.


Enantiomers

There is nothing strange about these left and right versions of a drug


Enantiomers of each other often show different chemical reactions with other substances that are also enantiomers. Since many molecules in the bodies of living beings are enantiomers themselves, there is sometimes a marked difference in the effects of two enantiomers on living beings. In drugs, for example, often only one of a drug's enantiomers is responsible for the desired physiologic effects, while the other enantiomer is less active, inactive, or sometimes even responsible for adverse effects.
Owing to this discovery, drugs composed of only one enantiomer ("enantiopure") can be developed to enhance the pharmacological efficacy and sometimes do away with some side effects. An example of this kind of drug is eszopiclone (Lunesta), which is enantiopure and therefore is given in doses that are exactly 1/2 of the older, racemic mixture called zopiclone. In the case of eszopiclone, the S enantiomer is responsible for all the desired effects, though the other enantiomer seems to be inactive; while an individual must take 2 mg of zopiclone to get the same therapeutic benefit as they would receive from 1 mg of eszopiclone, that appears to be the only difference between the two drugs.

Another good example is a common antihistamine:-
Levocetirizine (Xyzal) and cetirizine (Zyrtec)
Cetirizine, an effective H1-receptor antagonist, is a racemate mixture of two enantiomers: levocetirizine (R enantiomer) and dextrocetirizine (S enantiomer).  Chemically, levocetirizine is the active enantiomer of cetirizine. It is the L-enantiomer of the cetirizine racemate.
Cetirizine is sold as Zyrtec and Levocetirizine is sold as Xyzal.

If you prefer Claritin:
Claritin is loratadine.  The active half of this mixture is desloratadine.
So they have separated this out and produced a single-enantiomer drug made exclusively of desloratadine.  You can buy this as Clarinex/Aerius, depending on where you live.

In many cases the single-enantiomer drug works no better, it just costs more and may allow for a patent to be extended, which may mean billions of extra dollars.

Single-enantiomer drugs: elegant science, disappointing effects.
Abstract
Most new drugs are marketed as single enantiomers but many older agents are still available in racemic form. As these drugs reach the end of their patent life manufacturers become interested in marketing single enantiomer equivalents. This is called 'chiral switching' and it has been claimed that it will bring clinical benefits in terms of improved efficacy, more predictable pharmacokinetics or reduced toxicity. We reviewed the clinical evidence and prices for three recently marketed single enantiomer versions of widely used racemic drugs: escitalopram, esomeprazole and levosalbutamol. Claims of increased efficacy were based on comparisons of non-equivalent doses and any advantages seemed small and clinically unimportant. Prices of esomeprazole and levosalbutamol were higher than their racemic alternatives and we predict that these prices will remain high despite the market presence of generic versions of the racemates. Patent protection and a perception of superiority based on promotion rather than evidence will maintain price premiums for single enantiomer drugs that are not justified on the basis of clinical performance


Back to Russia

In Russia they have now marketed the single enantiomer drug of Pantogam, which is called Pantogam Aktiv.
Does Pantogam Aktiv work “better” than Pantogam, or does it just cost more?
Is Pantogam Aktiv equivalent to R-baclofen (arbaclofen)?

How would those eight kids with Asperger's in the UK fare on Pantogam Aktiv, as opposed to Baclofen?  Is tolerance an issue with Pantogam Aktiv? 

“Failed” Arbaclofen Trial
Rather than spend tens of millions of dollars on Arbaclofen, why did not someone just think of first trying Pantogam and Pantogam Aktiv on that very first child who responded to Baclofen?
When they closed the trial (and the company) why did they not suggest to those unhappy parents to try Pantogam and Pantogam Aktiv?

Pantogam Research
Most research is in Russian, but there is some in English.  Interestingly this drug affects both GABAA and GABAB.
While its main effect is on GABAB. like Baclofen, it also has the effect of modulating the GABAA response.  This effect means that when combined with benzodiazepines, where normally people build up a tolerance, and so the dose needs to be increased, no tolerance develops.  We saw this very effect on GABAA with tiny doses of other drugs in earlier posts.

 A total of 32 children aged 6–12 years with attention deficit hyperactivity disorder (ADHD) were monitored during prolonged (6–8 months) treatment with Pantogam (homopantothenic acid) at daily doses of 500–1000 mg. Treatment results were assessed using the DSM-IV core ADHD symptom scales and the WFIRS-P (parental) scale every two months. Decreases in core symptoms on the DSM-IV core ADHD symptom scale were seen at two months of treatment. Significant changes on the WFIRS-P scale took longer: improvements in self-concept, socialization, and social activity were seen at four months and in behavior and schoolwork, basic life skills, along with decreases in risk-associated behavior, at six months. Thus, in contrast to regression of core ADHD symptoms, overcoming impairments in social-psychological adaptation required longer treatment periods.




Conclusion
Arbaclofen (R-Baclofen) failed its clinical trial, so it is no wonder drug for Fragile X and classic autism, but is was effective in a minority of people. 
It is possible that it would have been much more effective on people at the other end of the spectrum, those with Asperger’s – like the reader of this blog and the UK pediatrician using cheap Baclofen.
The people behind the Arbaclofen trial were super-brainy types from MIT, dig a bit deeper and I recall family links to Fragile-X.  So objectivity went out of the window, along with all those millions of dollars.
I do not suppose Pantogam and Pantogam Aktiv are autism wonder drugs, but they must help in some cases, otherwise the Russians would not be prescribing them. 
For those who found Arbaclofen really did help, why not try Pantogam and Pantogam Aktiv?  Just use Google:- “Buy Pantogam” in place of “Buy Arbaclofen”.
You would have thought someone smart at the US NIMH would have thought of this.  There are some very clever Russians and they do have autism over there too.

Biotin & Triglycerides - why perhaps Fish Oil and Niacin may actually help a little in Autism & Schizophrenia

Far back in this blog, I wrote a post about fish oil.  Omega 3 oils are definitely good for your general health, but do they help with autism?  They are also claimed to help with ADHD and improve your NT child’s cognitive performance.

On critical review of the evidence, it seemed that the benefit was far from conclusive.  There was one very positive study, that neither the authors nor anyone else could repeat.

The following review of the literature by the University of Maryland show that, as with autism, studies on fish oil in depression, ADHD, bipolar and schizophrenia show conflicting results.


Some of the “cognitive enhancing” fish oil products are extremely expensive and I showed that regular fish consumption was far cheaper and likely to be as effective.

There is an issue of just how big an effect you are looking for.  We can all imagine tiny effects, but you really want an effect that everyone else notices.

Monty, aged 11 with ASD, eats lots of fish, mainly because he loves it.  He is not at all put off by those little bones.

The effect of fish oil on Monty was not noticeable.


Biotin

A recent post contained a study from Greece, where they found a remarkably high proportion of kids with ASD with a biotin deficiency.  This had not shown up on the standard test, because the standard test is strangely not for biotin at all; it tests for biotinidase, a related enzyme.

Identifying a biotin deficiency is not easy, blood tests are not helpful and you have to look at certain compounds found in urine.  As a result your local laboratory may not offer a useful test for biotin.

Since supplementation with pharmacological doses of biotin is known to be harmless, the practical way forward is to try it.

In the midst of looking at the relative effect of different primary antioxidants, I was substituting one thiol antioxidant (ALA) for another (NAC) to see if there was any obvious difference.  I could give lots of reasons, with scientific papers to back them up, as to why 0.6g of ALA plus 1.8g of NAC might be “better” than 2.4g of NAC, but it is not.  If anything, it might be worse.

Then I tried Carnosine in combination with NAC and again I could see absolutely no effect.

Then I decided to go back to my original NAC regime and add the biotin that had been on the shelf since Christmas. Very surprisingly, the effect that I thought might show up with ALA, showed up with biotin.  

It was not a huge effect, but a small step forward, that Monty’s assistant at school also noticed.  He was more calm and altogether more "normal". 

Does this mean Monty has a biotin deficiency?  It is of course possible.  In the Greek study 4% of the kids were thought to have such a deficiency, far more than expected, and most did respond, in varying degrees, to biotin supplements.  Unfortunately they only gave the biotin to the 4%; I would like to know what would have happened to the remaining 96%.


Biotin lowers Triglycerides and Elevated Triglycerides are associated with Mood Disorders   

Biotin is a B vitamin, but very little is actually known about it.

Then I found the link I was looking for.

Biotin does not lower cholesterol, but it does reduce (in a big way) your Triglycerides.

Several studies have shown that elevated Triglycerides are associated with all kinds of disorders: bipolar, depression and schizophrenia.  These studies suggested a causal link between the mood disorder and the elevated triglyerides.

Other Effects on Mood

          Besides depression, high levels of triglycerides are also correlated with other affective disorders including bipolar disorder (manic depression), schizoaffective disorders, aggression and hostility. In fact, the poor nutritional status of many depressed persons, who often have diets high in fats, can be improved to lessen the depression, according to Charles Glueck, MD, medical director of the Cholesterol Center of Jewish Hospital in Cincinnati.
"We have shown that in patients with high triglycerides who were in a depressive state, the more you lower the triglycerides, the more you alleviate the depression," Glueck wrote in a 1993 article in Biological Psychiatry.
According to the U.S. Centers for Disease Control and Prevention (CDC), most Americans aren't aware of the role triglycerides play in physical and mental health. A five-year study of more than 5,000 Americans found that 33 percent of them had borderline high triglyceride levels.


Improvement in symptoms of depression and in an index of life stressors accompany treatment of severe hypertriglyceridemia.


In 14 men and nine women referred because of severe primary hypertriglyceridemia, our specific aim in a 54-week single-blind treatment (Rx) period was to determine whether triglyceride (TG) lowering with a Type V diet and Lopid would lead to improvement in symptoms of depression, improvement in an index of life stressors, change in locus of control index, and improved cognition, as serially tested by Beck (BDI), Hassles (HAS) and HAS intensity indices, Locus of Control index, and the Folstein Mini-Mental status exam. On Rx, median TG fell 47%, total cholesterol (TC) fell 15%, and HDLC rose 19% (all p < or = 0.001). BDI fell at all nine Rx visits (p < or = 0.001), a major reduction in a test of depressive symptoms. The HAS score also fell at all nine visits (p < or = 0.05 - < or = 0.001). Comparing pre-Rx baseline BDI vs BDI at 30 and 54 weeks on Rx, there was a major shift towards absence or amelioration of depressive symptoms (chi 2= 5.9, p = 0.016). On Rx, the greater the percent reduction in TG, the greater the percent fall in BDI (r = 0.47, p < or = 0.05); the greater the percent reduction in TC, the greater the percent fall in HAS (r = 0.41, p < or = 0.05). Improvement in the BDI and HAS accompanied treatment of severe hypertriglyceridemia, possibly by virtue of improved cerebral perfusion and oxygenation. There may be a reversible causal relationship between high TG and symptoms of depression.


Mood symptoms and serum lipids in acute phase of bipolar disorder inTaiwan.

 

Abstract

Serum lipids have been found to play important roles in the pathophysiology of mood disorders. The aim of the present study was therefore to investigate the relationship between symptom dimensions and serum cholesterol and triglyceride levels, and to explore correlates of lipid levels during acute mood episodes of bipolar I disorder in Taiwan. Measurements were taken of the serum cholesterol and triglyceride levels in patients with bipolar I disorder hospitalized for acute mood episodes (68 manic, eight depressive, and six mixed). The relationships between serum lipids levels and various clinical variables were examined. The mean serum levels of cholesterol (4.54 mmol/L) and triglycerides (1.16 mmol/L) of sampled patients were comparable to those of the general population in the same age segment. Severe depressive symptoms and comorbid atopic diseases were associated with higher serum cholesterol levels. A negative association was noted between serum triglyceride levels and overall psychiatric symptoms. Compared with previous studies on Western populations, racial differences may exist in lipids profiles of bipolar disorder patients during acute mood episodes. Increased serum cholesterol levels may have greater relevance to immunomodulatory system and depressive symptoms, in comparison with manic symptoms.


Biotin supplementation reduces plasma triacylglycerol and VLDL in type 2 diabetic patients and in non-diabetic subjects with hypertriglyceridemia.



Abstract

Biotin is a water-soluble vitamin that acts as a prosthetic group of carboxylases. Besides its role as carboxylase prosthetic group, biotin regulates gene expression and has a wide repertoire of effects on systemic processes. The vitamin regulates genes that are critical in the regulation of intermediary metabolism. Several studies have reported a relationship between biotin and blood lipids. In the present work we investigated the effect of biotin administration on the concentration of plasma lipids, as well as glucose and insulin in type 2 diabetic and nondiabetic subjects. Eighteen diabetic and 15 nondiabetic subjects aged 30-65 were randomized into two groups and received either 61.4 micromol/day of biotin or placebo for 28 days. Plasma samples obtained at baseline and after treatment were analyzed for total triglyceride, cholesterol, very low density lipoprotein (VLDL), glucose and insulin. We found that the vitamin significantly reduced (P=0.005) plasma triacylglycerol and VLDL concentrations. Biotin produced the following changes (mean of absolute differences between 0 and 28 day treatment+/-S.E.M.): a) triacylglycerol -0.55+/-0.2 in the diabetic group and -0.92+/-0.36 in the nondiabetic group; b) VLDL: -0.11+/-0.04 in the diabetic group and -0.18+/-0.07 in the nondiabetic group. Biotin treatment had no significant effects on cholesterol, glucose and insulin in either the diabetic or nondiabetic subjects. We conclude that pharmacological doses of biotin decrease hypertriglyceridemia. The triglyceride-lowering effect of biotin suggests that biotin could be used in the treatment of hypertriglyceridemia.





Abstract
In addition to its role as a carboxylase cofactor, biotin modifies gene expression and has manifold effects on systemic processes. Several studies have shown that biotin supplementation reduces hypertriglyceridemia. We have previously reported that this effect is related to decreased expression of lipogenic genes. In the present work, we analyzed signaling pathways and posttranscriptional mechanisms involved in the hypotriglyceridemic effects of biotin. Male BALB/cAnN Hsd mice were fed a control or a biotin-supplemented diet (1.76 or 97.7 mg of free biotin/kg diet, respectively for 8 weeks after weaning. The abundance of mature sterol regulatory element-binding protein (SREBP-1c), fatty-acid synthase (FAS), total acetyl-CoA carboxylase-1 (ACC-1) and its phosphorylated form, and AMP-activated protein kinase (AMPK) were evaluated in the liver. We also determined the serum triglyceride concentrations and the hepatic levels of triglycerides and cyclic GMP (cGMP). Compared to the control group, biotin-supplemented mice had lower serum and hepatic triglyceride concentrations. Biotin supplementation increased the levels of cGMP and the phosphorylated forms of AMPK and ACC-1 and decreased the abundance of the mature form of SREBP-1c and FAS. These data provide evidence that the mechanisms by which biotin supplementation reduces lipogenesis involve increased cGMP content and AMPK activation. In turn, these changes lead to augmented ACC-1 phosphorylation and decreased expression of both the mature form of SREBP-1c and FAS. Our results demonstrate for the first time that AMPK is involved in the effects of biotin supplementation and offer new insights into the mechanisms of biotin-mediated hypotriglyceridemic effects.


Triglycerides are also elevated in autism:-



Abstract

We hypothesize that autism is associated with alterations in the plasma lipid profile and that some lipid fractions in autistic boys may be significantly different than those of healthy boys. A matched case control study was conducted with 29 autistic boys (mean age, 10.1 +/- 1.3 years) recruited from a school for disabled children and 29 comparable healthy boys from a neighboring elementary school in South Korea. Fasting plasma total cholesterol (T-Chol), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), the LDL/HDL ratio, and 1-day food intakes were measured. Multiple regression analyses were performed to assess the association between autism and various lipid fractions. The mean TG level (102.4 +/- 52.4 vs 70.6 +/- 36.3; P = .01) was significantly higher, whereas the mean HDL-C level (48.8 +/- 11.9 vs 60.5 +/- 10.9 mg/dL; P = .003) was significantly lower in cases as compared to controls. There was no significant difference in T-Chol and LDL-C levels between cases and controls. The LDL/HDL ratio was significantly higher in cases as compared to controls. Multiple regression analyses indicated that autism was significantly associated with plasma TG (beta = 31.7 +/- 11.9; P = .01), HDL (beta = -11.6 +/- 2.1; P = .0003), and the LDL/HDL ratio (beta = 0.40 +/- 0.18; P = .04). There was a significant interaction between autism and TG level in relation to plasma HDL level (P = .02). Fifty-three percent of variation in the plasma HDL was explained by autism, plasma TG, LDL/HDL ratio, and the interaction between autism and plasma TG level. These results indicate the presence of dyslipidemia in boys with autism and suggest a possibility that dyslipidemia might be a marker of association between lipid metabolism and autism.


Omega-3 Oil and Niacin in Schizophrenia

Like Autism, Schizophrenia is another observational diagnosis, with many different underlying genetic and environmental causes.  I keep referring to it as adult-onset autism.  It is also characterized by oxidative stress.

I found it interesting that two very widely used therapies for schizophrenia are omega-3 fish oil and high doses of niacin.  2 g a day of NAC is another common therapy in schizophrenia.

The clinical trials of omega-3 oil in schizophrenia, are just like the ones in autism, far from conclusive.  Yet people with schizophrenia continue to buy the expensive EPA fish oils, just like many parents of children with autism.

Another very popular treatment is Niacin.

Niacin does many things but these include increasing your HDL (good) cholesterol, reduce LDL (bad) cholesterol and, importantly, can reduce triglycerides by up to 50%.



Niacin in Anxiety



Niacin in autism

People do use high dose niacin and niacinamide in autism, but in general niacin levels are totally normal in people with autism, according to this study:-


For the vitamins, the only significant difference was a 20% lower biotin (p < 0.001) in the children with autism. There were possibly significant (p < 0.05) lower levels of vitamin B5, vitamin E, and total carotenoids. Vitamin C was possibly slightly higher in the children with autism. Vitamin B6 (measured as the active form, P5P, in the RBC) had an unusually broad distribution in children with autism compared to controls (see Figure Figure1),1), with the levels in the children with autism having 3 times the standard deviation of the neurotypical children.

Niacin was very similar in the autism group (7.00 μg/l and the control group (7.07 μg/l)

Other interesting findings highlighted the usual metabolic differences:-

·        ATP, NADH, and NAHPH were significantly different between the autism and neurotypical groups
·        Sulfation, methylation, glutathione, and oxidative stress biomarkers which were significantly different between the autism and neurotypical groups
·        Amino Acids which were significantly different between the autism and neurotypical groups, rescaled to the average neurotypical value



Peter Triglyceride Hypothesis in Autism & Schizophrenia

Elevated triglycerides in autism/schizophrenia may contribute to behavioral/mood problems.  The lipid contribution to the dysfunction may be correlated to elevation of triglycerides.  In other words triglycerides aggravate the existing disorder.

Some CAM treatments currently used in autism/schizophrenia, including high dose niacin, high dose biotin and high dose omega 3 oils may be effective due to their ability to lower triglycerides.

Biotin may be the safest, cheapest and most effective option to reduce triglycerides and improve mood/behavior.

The underlying cause of lipid dysfunction in autism/schizophrenia is the ongoing oxidative stress.


Fish oil is claimed to be good for your heart, but it has been shown not to affect cholesterol levels.  In some studies it did lower triglycerides.  In some countries doctors prescribe omega-3 oil to patients with stubbornly high triglycerides.  Perhaps they should read the research and try biotin?


  

Other functions of biotin


Biotin does have other more complex functions and the triglycerides may, so to speak, be a red herring.

Regulation of gene expression by biotin (review).

Abstract

In mammals, biotin serves as coenzyme for four carboxylases, which play essential roles in the metabolism of glucose, amino acids, and fatty acids. Biotin deficiency causes decreased rates of cell proliferation, impaired immune function, and abnormal fetal development. Evidence is accumulating that biotin also plays an important role in regulating gene expression, mediating some of the effects of biotin in cell biology and fetal development. DNA microarray studies and other gene expression studies have suggested that biotin affects transcription of genes encoding cytokines and their receptors, oncogenes, genes involved in glucose metabolism, and genes that play a role in cellular biotin homeostasis. In addition, evidence has been provided that biotin affects expression of the asialoglycoprotein receptor and propionyl-CoA carboxylase at the post-transcriptional level. Various pathways have been identified by which biotin might affect gene expression: activation of soluble guanylate cyclase by biotinyl-AMP, nuclear translocation of NF-kappaB (in response to biotin deficiency), and remodeling of chromatin by biotinylation of histones. Some biotin metabolites that cannot serve as coenzymes for carboxylases can mimic biotin with regard to its effects on gene expression. This observation suggests that biotin metabolites that have been considered "metabolic waste" in previous studies might have biotin-like activities. These new insights into biotin-dependent gene expression are likely to lead to a better understanding of roles for biotin in cell biology and fetal development.


It does appear that biotin is more important than generally appreciated. 



Conclusion

In earlier posts I highlighted that elevated cholesterol is a bio-marker for inflammation.  In a large sub-group in autism, cholesterol is elevated.

In today’s post we looked at  a different type of lipid, triglycerides, they have a different role to cholesterol.  Not surprisingly the lipid profile is dysfunction, since it is closely linked to oxidative stress, which appears to be at the root of many problems in autism.

It is extremely easy and inexpensive to check your lipid profile (LDL, HDL and triglycerides); if elevated, there are safe established ways to bring things back to “normal”.

Parents seeing a small positive effect with their fish oil supplements might consider saving a lot of money and seeing if an extremely inexpensive biotin (5mg) supplement has an equal or greater effect.  The cost of biotin would be $2 a month.  The cost of fish oil with anything like the concentration used in the more effective trials (0.84g EPA and 0.7g DHA) will cost around $50 a month and may not lower triglycerides by as much as the cheap biotin.

By measuring the lipid profile before and after, you will be able to determine for yourself the relative merits.

Niacin also has been shown to improve mood/anxiety.  It is used by people with autism and schizophrenia.  Niacin is also extremely effective at reducing triglycerides.  High doses of Niacin can be accompanied by side effects and so use is discouraged.

Biotin levels do seem to be slightly low in autism.  Effective methods of accurately diagnosing deficiency are disputed.  Biotin is very effective at reducing triglycerides.

Elevated triglycerides have been associated with mood disorders and depression.

It seems plausible that the benefits from Omega-3 , niacin and biotin stem from their effectiveness in reducing triglycerides.


Biotin would seem to be a very cost effective and safe way to achieve this, without the side effects of niacin.  

Biotin also appears to have other key functions, including transcription of cytokine genes. Over expression of pro-inflammatory cytokines is a common feature of autism.

“Spray Fire in my Head” and how putting it out with Verapamil links Histamine, IL6, Mast cells, Calcium Channel Cav1.2, and even the Vagus Nerve


After 18 months of researching autism, things are falling nicely into place.  For regular readers of this blog, it may seem that we have uncovered a bewildering number of issues/dysfunctions that need to be addressed by the science.  In fact, when you look closer still, you will see that many of these issues are interrelated and you do not need to treat each one.  Also, it is clear that many different methods can be used to treat the same dysfunction.  The best methods though would be the simplest, safest, cheapest and the ones that address multiple issues at once.

One such little gem is Verapamil, an extremely cheap calcium channel blocker that has been widely used for 30 years for other conditions. 


Spray Fire in my Head

Monty, aged 10 with ASD, suffers from allergies like many children.  I noticed that his pollen allergy provoked a dramatic increase in his autistic behaviors.  Last year I spent time developing a treatment for these summertime autism flare-ups, to avoid summertime misery for all of us.

My final secret weapon was not a commonly known allergy drug; in fact almost nobody would even consider it for this purpose, except those who read the old research.

Where we live, last the weekend the air was full of tree pollen and it was 280 C/ 820 F; so I was expecting a response from Monty.

He soon had red eyes, briefly rolled about on the floor and declared “spray fire in my head”.

In anticipation of the pollen season, for the last few weeks I have been giving him some mast cell stabilizing treatments, but clearly they were not sufficient; so I mixed up some extra verapamil, and as expected, a few minutes later peace was fully restored.

I have told you about channelopathies in previous posts.  Verapamil blocks the calcium channel called Cav1.2, but I did not tell you that in addition to this Cav1.2 channel affecting behavior and heart disease, it also appears to directly affect allergies and even the vagus nerve.

It would seem that one cheap little pill can address all of these issues.


The take-home points from the literature are these:-

Verapamil is very widely prescribed calcium channel blocker, used to lower blood pressure; but in the literature it is shown that:-
  • Verapamil inhibits mast cells and is shown to successfully treat asthma
  • Verapamil is more potent than the allergy drug Azelastine (the best mast cell stabilizing anti-histamine drug available)
  • Verapamil will reduce histamine release and therefore inflammatory cytokine Interleukin-6 (IL6), already elevated in autism
  • Verapamil activates the Gene for IL6
  • Verapamil alters the balance between parts of the autonomic nervous system's function, with a shift toward decreased sympathetic tone and increased parasympathetic (vagus nerve) tone
  • Autism is associated with an atypical autonomic response to anxiety that is most consistent with sympathetic over-arousal and parasympathetic under-arousal.  So increasing the parasympathetic (vagus nerve) tone is desirable.
  
Verapamil, Allergies and Asthma

Pollen allergies are a common trigger for asthma, and since every year many people die from asthma, the underlying science is well researched/understood.

  
Discussion
This study has demonstrated, for the first time, that mast cell tryptase potentiates the contractile response to histamine in human isolated airways. Moreover, this potentiation occurs only in tissues derived from patients whose bronchi exhibit a contractile response to antigen, i.e. which are sensitized. The potentiation was not observed in nonsensitized tissue. The mechanism underlying the tryptase-induced potentiation is related to Ca2+ flux through voltage-dependent channels, since it was inhibited by verapamil.

Inhibition of rat mast cell degranulation by verapamil.

Abstract
Calcium antagonists, e.g. verapamil, prevent exercise-induced asthma. This protective effect may proceed from inhibition of contraction of bronchial smooth muscle, release of mediators by primary effector cells, e.g. mast cells, or both. Therefore, we studied the inhibitory effect of increasing concentrations of verapamil on both in vitro antigen-induced degranulation and ionophore A23187-induced release of labelled serotonin by rat peritoneal mast cells. There was a dose-dependent inhibition by verapamil of both ovalbumin-induced degranulation of mast cells passively sensitized by incubation with mice IgE-rich serum and ionophore-induced release of tritiated serotonin by mast cells previously incubated with (3H)-5HT; the 50% inhibiting concentration was 1.4 X 10(-4) mol I-1 and 5.2 X 10(-5) mol I-1, respectively. An attractive explanation of our results is that verapamil inhibits the antigen-induced release of mediators by mast cells through its calcium antagonist effect. Our results also suggest that the preventing effect of calcium antagonists on asthma may be multi-factorial since other authors have clearly shown that these drugs inhibit contraction of guinea-pig tracheal smooth muscle in vitro.

COMPARATIVE STUDY OF AZELASTINE AND VERAPAMIL IN THE MODIFICATION OF OVALBUMIN SENSITIZED LUNGPARENCHYMAL TISSUES OF GUINEA PIGS IN VITRO

The inhibition of mediator released by Azelastine may help to explain their protective action in anaphylaxis. Our observations are in agreement that Azelastine exerts inhibitory effect on synthesis and release of chemical mediators from mast cell (Chand et al., 1983), including the leukotrienes (Hamasaki et al., 1996).

 Azelastine is a second-generation antihistamine approved for treatment ofallergic conditions. This randomized, double-blind, placebo- and active-controlled, parallel group clinical trial evaluated the efficacy and safety of Azelastine in patients with moderate to-severe seasonal allergic conditions (Shah et al., 2009).  Reussi et al. (1980) have demonstrated the inhibition of release of chemical mediators from mast cells by Ca++ channel blocker in animals in vivo and demonstrate the inhibition of antigen-induced brocho-constriction by Verapamil in sheep, allergic to ascaris sum antigen but Verapamil failed to block in the same non-sensitized animal. It is speculated that calcium channel blocker protect against the allergic broncho-constriction predominantly by preventing the release of chemical mediators from the mast cells.

Fig. 2. Graph shows dose dependent inhibitory effect of Azelastine and Verapamil with the treatment of EC50 ovalbumin. Line in the box indicates the ovalbumin EC50 induced contraction (Control). Each point represent mean of six observationsSyed Saud Hasan et al. 49  On the other hand Henderson et al. (1983) found significant inhibition of allergic response with Nifedipine and Lee at al. (1983) also supported the finding, which observed inhibition of mediator release from human lung in vitro by Verapamil.

   Verapamil in concentration 10-10 g/ml did not exhibit any inhibition but as the concentration increases to 10-9 g/ml showed marked inhibition in contractile effect of ovalbumin EC50 (0.3x10-6). Further increases in concentration of Verapamil i.e. 10-8 g/ml completely antagonized the ovalbumin induced contraction. Azelastine in concentration of 10-9 g/ml (1ng/ml) did not exhibit any inhibition as the concentration increase to 10-8 g/ml showed mark inhibition i.e. 20% contraction to EC50 (0.3x10-6) ovalbumin, when compared before treatment with Azelastine and the concentration 10-7 g/ml antagonized the effect of EC50 (Table and Figure 2).







CONCLUSION It can be inferred from the observations that response produced by antigen can be controlled better with Verapamil than Azelastine and emerging with similar activity regardless of exact mechanism involved.




Verapamil and the IL-6 Gene


Conclusions—The results demonstrate that CCB of all 3 subclasses are capable of activating NF-IL6 and NF-kB. CCB may thus directly regulate cellular functions by affecting the activity of transcription factors independent of changes of intracellular calcium concentrations, an observation that is of interest considering the biological effects induced by CCB.

A major result of our investigations is the discovery of the activation of  transcription factors resulting from CCB treatment. In general, CCB are postulated to exert their biological effects by decreasing the intracellular concentration of calcium ions.1–4 Experimentally, this effect is usually achieved at micromolar concentrations of the drugs. However, accumulating evidence suggests that CCB, used at therapeutically effective doses (ie, at the nanomolar range), activate calcium in dependent signal transduction pathway(s) altering gene expression.14–17 Here, we show that CCB directly activate the transcription factors NF-IL6 and NF-kB in human VSMC, independent of intracellular calcium levels. This is supported by the existence of multiple regulatory regions within the intracellular part of the L-type calcium channel. It remains to be investigated, however, along which signal transduction pathway this action of CCB occurs.


Verapamil and the Vagus Nerve

Two of the most popular subjects on this blog are “autism and allergies” and “autism and the vagus nerve”.

The vagus nerve connects many parts of the body and seems to be a conduit for inflammatory signaling within the body.  It is deeply involved the process leading to arthritis and epilepsy; by stimulating this nerve with electrical signals, both epilepsy and arthritis can be reduced markedly in certain people.  It is often suggested that the GI problems in many autistic people and linked to aberrant behaviors via the vagus nerve, what some call the “gut brain connection”.

To understand what is going on and why is does affect autism we need to introduce something new, the autonomic nervous system.  For those who already know about this, the interesting finding is that:-

Verapamil alters the balance between parts of the autonomic nervous system's function  with a shift toward decreased sympathetic tone and increased parasympathetic (vagus nerve) tone.

The source of this statement is:


and their sources were:-




We learned in an earlier post about autism and the Vagus Nerve that it seems to link many strange things in autism.

We learned from Professor Porges that, for example, the neural mechanism for making eye contact is shared with those needed to listen to the human voice; people with autism struggle with both.  Anything that can “wake up” the vagus nerve system could be interesting.
  

In the complicated science we will see that the vagus nerve is also called the parasympathetic nervous system.  The paper below shows how this parasympathetic (Vagus) system is out of balance with the opposing sympathetic nervous system, this then leads to anxiety commonly found in autism.


Assessment of anxiety symptoms in autism spectrum disorders (ASD) is a challenging task due to the symptom overlap between the two conditions as well as the difficulties in communication and awareness of emotions in ASD. This motivates the development of a physiological marker of anxiety in ASD that is independent of language and does not require observation of overt behaviour. In this study, we investigated the feasibility of using indicators of autonomic nervous system (ANS) activity for this purpose. Specially, the objectives of the study were to 1) examine whether or not anxiety causes significant measurable changes in indicators of ANS in an ASD population, and 2) characterize the pattern of these changes in ASD. We measured three physiological indicators of the autonomic nervous system response (heart rate, electrodermal activity, and skin temperature) during a baseline (movie watching) and anxiety condition (Stroop task) in a sample of typically developing children (n = 17) and children with ASD (n = 12). The anxiety condition caused significant changes in heart rate and electrodermal activity in both groups, however, a differential pattern of response was found between the two groups. In particular, the ASD group showed elevated heart rate during both baseline and anxiety conditions. Elevated and blunted phasic electrodermal activity were found in the ASD group during baseline and anxiety conditions, respectively. Finally, the ASD group did not show the typical decrease in skin temperature in response to anxiety. These results suggest that 1) signals of the autonomic nervous system may be used as indicators of anxiety in children with ASD, and 2) ASD may be associated with an atypical autonomic response to anxiety that is most consistent with sympathetic over-arousal and parasympathetic under-arousal.



The following explanation of the Autonomic Nervous System is edited from Wikipedia.


Autonomic Nervous System (ANS)

The autonomic nervous system (ANS) is the part of the peripheral nervous system that acts as a control system that functions largely below the level of consciousness to control functions,] including heart rate, digestion, respiratory rate, salivation, perspiration, pupillary dilation, micturition (urination), sexual arousal, breathing and swallowing. Most autonomous functions are involuntary but they can often work in conjunction with the somatic nervous system which provides voluntary control.

The ANS is divided into three main sub-systems:

PSNS is often considered the "rest and digest" or "feed and breed" system
SNS is often considered the "fight or flight" system
ENS consists of a mesh-like system of neurons that governs the function of the gastrointestinal system

Depending on the circumstances, these sub-systems may operate independently of each other or interact co-operatively.

In many cases, PSNS and SNS have "opposite" actions where one system activates a physiological response and the other inhibits it. The modern characterization is that the sympathetic nervous system is a quick response mobilizing system and the parasympathetic is a more slowly activated dampening system.

In general, ANS functions can be divided into sensory (afferent) and motor (efferent) subsystems. Within both, there are inhibitory and excitatory synapses between neurons. Relatively recently, a third subsystem of neurons that have been named 'non-adrenergic and non-cholinergic' neurons (because they use nitric oxide as a neurotransmitter) have been described and found to be integral in autonomic function, in particular in the gut and the lungs

Neurotransmitters and pharmacology

At the effector organs, sympathetic ganglionic neurons release noradrenaline (norepinephrine), along with other cotransmitters such as ATP, to act on adrenergic receptors, with the exception of the sweat glands and the adrenal medulla:
  • Acetylcholine is the preganglionic neurotransmitter for both divisions of the ANS, as well as the postganglionic neurotransmitter of parasympathetic neurons.
  • Nerves that release acetylcholine are said to be cholinergic. In the parasympathetic system, ganglionic neurons use acetylcholine as a neurotransmitter to stimulate muscarinic receptors.
  • At the adrenal medulla, there is no postsynaptic neuron. Instead the presynaptic neuron releases acetylcholine to act on nicotinic receptors. Stimulation of the adrenal medulla releases adrenaline (epinephrine) into the bloodstream, which acts on adrenoceptors, producing a widespread increase in sympathetic activity.

Conclusion

For those of you that made it this far, here are my conclusions.

People who have autism and any kind of allergy, be it pollen, food intolerance, asthma or anything similar, might consider asking their doctor to let them trial a very low dose of Verapamil for a couple of days.  The effect is almost instant and so there is no point trialing it for weeks.  Verapamil will lower your blood pressure, in a dose dependent fashion.  The effective autism dose for a severe allergy case is about 1mg/kg.  The half-life varies person to person, so you might need two doses a day, or you might need three.

If you know an adult with severe asthma, look hard and you may see some very mild signs of autism (need for order, anxiety, lack of flexibility etc).

It appears that in all these cases, the gene CACNA1C is misbehaving to varying degrees in different parts of the body.  This gene produces the calcium channel Cav1.2.

You could check if you have the mutated gene, but I do not see the point.  It would only tell you what might happen.  To know what actually has happened, you would need to use proteomics

This emerging science will ultimately be able to provide biomarkers for neurological conditions like autism, depression, bipolar etc, so that the neurologist will know, with certainly, what specific dysfunctions each individual person has.  At that point, behavioral assessments and psychiatry will finally be consigned to history and people will get “smart drugs”, to treat precisely diagnosed neurological dysfunctions.
