Title: COUPLED DYSBIOSIS


1
COUPLED DYSBIOSIS METABOLIC DYSFUNCTIONS IN
AUTISM POSSIBLE REMEDIES
  • Jon B. Pangborn, Ph.D., F.A.I.C., C.C.N.

2
TODAYS ASSIGNMENT
  • To explore how impaired methionine-to-taurine
    metabolism and reduced methylation, together with
    infection, impact autism. We will consider
    possible natural and nutritional remedies.

3
DISCLOSURES
  • Father of formerly autistic child now adult
  • Left chemical engineering 29 years ago to
    investigate biochemistry and autism
  • Past President, Doctors Data Laboratory
  • Klaire Labs Consultant 1981-1999
  • Great Smokies Diagnostic Lab (Genova) 1995-2005
  • Cofounder Defeat Autism Now! 1995
  • Coauthor Autism Effective Biomedical Treatments
  • Consultant Kirkman Labs since 2000
  • Senior Scientific Consultant, ARI

IN PERSPECTIVE
  • There are many different autisms
  • Primarily Genetic Mostly acquired
  • Inherited faults
  • toxic/infectious stressors
  • Considering ASD people as a group, there are
    cell-wide and extracellular anomalies.
  • Dont get hung up on one enzyme/protein, one cell
    compartment, one gene, one epigenetic process,
    one cytokine, one toxicant or infectious agent or
    any single theory or model.

5
TODAYS FOCUS
  • Deficient methylation of lipids adjacent to
    neuronal receptors can cause loss of neuronal and
    network synchrony. See Deth, Molecular Origins
    of Human Attention Kluwer Acad Pub, 2003.
  • Methionine metabolism can be disordered in
    multiple ways such that methylation is deficient,
    oxidant stress occurs, and an inflammation
    becomes a persistent, maladaptive condition.
  • Mitochondrial dysfunction is probable when
    vitamin B12 (as AdoCobalamin) and carnitine are
    deficient and maybe when Clostridia dysbiosis
    occurs.

6
TODAYS FOCUS2
  • Xenobiotic (e.g. organophosphate) and elemental
    (e.g. mercury) toxicants can be contributory.
  • Many infectious agents and foreign substances can
    lead to oxidant stress when taurine is deficient.
  • There are nutritional aids for methylation,
    reducing inflammation, mitochondrial support and
    alleviating dysbiosis.

    biochemical transformations
  • L-carnitine

    and a-ketoglutarate x 2

14
CARNITINE
  • CH3
  • CH3?N? CH2?CH?CH2?COOH
  • CH3 OH

15
ACTIONS OF CARNITINE
  • Using a translocase transporter, CARNITINE
    escorts fatty acids (as fatty-acyl carnitine)
    through the inner mitochondrial membrane.
  • Combines with excesses of organic acids
    (propionic, isovaleric, 3-methylglutaric,
    valproic, others) to accomplish a detoxication
    function.

16
REVIEW FOUR INTERRELATED PARTS OF BIOCHEMISTRY
  • 1. Methionine ? SAM, methylation ?? cysteine with
    some homocysteine recycle using methyls provided
    by folate to Cbl on MS.
  • 2. Cysteine ?? taurine or cysteine ?? GSH
  • Taurine scavenges OCl- GSH neutralizes H2O2
    and
  • during cellular immune and detoxifies and
    makes B12
  • defense activities. work.
  • 3. B12 ??GSCbl cytosolic homocysteine ?
    methionine and mitochondrial cleanup of
    propionate via MMA
  • 4. Carnitine, needs methylation for formation,
    also cleans up propionate and other excess
    organic acids.

17
WHATS GOING WRONG?SO MUCH THAT WE HAVE TO STUDY
IT PIECEWISE
  • METHIONINE ? SAM ? S-ADENOSYLHOMOCYSTEINE
  • methylation
  • Reduced methylation causes varying deficiencies
    of
  • melatonin choline/TMG/DMG
  • creatine methylated catecholamines
  • carnitine methylated CG pairs on DNA
  • methylated
    fatty acids
  • Remedies supplements of melatonin, creatine,
    L-carnitine, TMG, DMG. See ARI Publication 34.

18
CAN A VIRUS IMPAIR METHYLATION IN NEURONS?
  • Note Documentation in rat brain cells of reduced
    neuronal receptor phospholipid methylation during
    paramyxovirus infection (measles, mumps) Münzel
    and Koschel, Proc. Natl. Acad. Sci. (USA) 79
    (1982) 3692-6.
  • ?-adrenergic receptors affected loss of
    catecholamine-stimulated methylation

19
  • SAH HOMOCYSTEINE (Hcy) METHIONINE
  • ADENOSINE
  • CYSTATHIONINE
    CYSTEINE
  • Adenosine accumulates, SAH accumulates, SAH/SAM
    ratio increases, methylation slows. Adenosine
    elevated in ASD, 20 per plasma, 33 per RBCs.
  • Adenosine Deaminase (ADA) Binding Protein DPP4
    or CD26 is inhibited by mercury, antimony, lead,
    orga-nophosphates, streptokinase, casomorphin
    peptides.
  • See Püschel et al. Eur J Biochem 126 (1982)

  • 3. Genetic variants for ADA, methionine synthase,
    formation of cystathionine and methylated folate
    risk factors for ASD.
  • 4. Hcy ? Methionine hindered by oxidation of
    reduced cobalamin (Co1)
  • 5. Some Hcy tied up as Hcy thiolactone if PON
    (paraoxonase, Hcy thiolactonase) weak
    organophos-phate toxicity 40-fold activity

    mostly elevated beta-alanine

  • CYSTEINE TAURINE
  • REMEDIES FOR POSSIBLE PROBLEMS
  • Antiinflammatory meds, digestive aids
  • B6/P5P, zinc, magnesium, melatonin

  • Taurine, 100-250 mg/day with breakfast

24
RELEASE OF OXIDANTS BY PHAGOCYTIC NEUTROPHILS
(PMN LEUKOCYTES) WHEN TAURINE IS INADEQUATE
  • Phagocyte a cell that ingests microorganisms,
    foreign particles, other cells, and kills,
    digests or decomposes them.
  • Oxidant killing is a normal, body-defense
    mechanism
  • Respiratory Burst O2-, H2O2, OCl-
  • Taurine limits collateral damage by scavenging
    OCl-
  • See Dinauer et al., Chapt 189 in Scriver et al.,
    Eds., The Metabolic and Molecular Bases of
    Inherited Disease, 8th Ed.

    Proteus, Klebsiella, Microbacteria, others)

    rhino, papilloma, rotoviruses)

27
CLOSTRIDIA OVERGROWTH
  • Anaerobic organism cant assay by standard
    culture, often identified by chemical markers
    propionic acid, phenyl hydroxyphenyl
    propionates, indole propionate, phenol,
    para-cresol, acetic acid, acetates,
    phenyllactate.
  • - See Elsden et al. Arch.Microbiol 107,3
    (1976) 283-8
  • Many types C.difficile, propionicum, tetani
    (credit to Ellen Bolte, 1996), sporogenes,
    botulin, and many more.
  • Propionic acid and propionates induce autistic
    behavior in rats See work of Derrick MacFabe.

28
CLOSTRIDIUM DIFFICILE ANTIBIOTIC RESISTANT STRAIN
  • First public notice Warrey Pipin - Lancet
    2005 Cloud Kelly Curr Opinion Gastroenterol
    23,1 (207) 4-9 Baines OConnor
    J.Microb.Chemother 62,5 (2003) 1078-85 Spigaglia
    et al. PMID 18480338 Saxon et al. PMID 18710908
  • Vancomycin sends it to spore form later it comes
    back with a vengeance
  • Ciprofloxacin, Levofloxacin and 20 more
    antibiotics (esp. fluoroquinolones) have no
    lasting effect. What almost kills it, makes it
    stronger.

29
NATURAL ANTIBIOTIC FUNCTION IS A TWO-PRONGED
ATTACK
  • Toxic killing agents, plus
  • Agent that disables organisms defenses
  • See Proc.Natl.Acad.Sci (USA) 97 (2000) 1433
  • Drs. Lewis (Tufts) and Stermitz (Col. State U)
  • Studied Barberry berberine 5methoxyhydnocarpin

WHAT HERBALS HAVE NATURAL ANTIBIOTIC ACTION
AGAINST CLOSTRIDIA?
  • Thyme, oregano, cumin (at low levels). See Dorman
    Dean, J. Appl.Microbiol. 88 (2000) 308-16
  • Curcumin (turmeric) provides antioxidant
    protection, lowers cytokines (inc. TNF-a),
    regulates COX-2 and downregulates NF-Kappa B.

    difficile disease. S. boulardii and Lactobacilus
    rhamnosis both reduce antibiotic-associated
    diarrhea.

SHORT HISTORY OF MEDICINE
  • Problem I have an earache.
  • 2000 B.C. Here, eat this root.
  • 1000 A.D. That root is heathen. Here, say this
    prayer.
  • 1850 A.D. That prayer is superstition. Here,
    drink this potion.
  • 1940 A.D. That potion is snake oil. Here, swallow
    this pill.
  • 1985 A.D. That pill is ineffective. Here, take
    this antibiotic.
  • 1997 A.D. That antibiotic ruins your own
    immunity. Here, eat this root.
