Food allergies


Published on

In his third of five lectures, Dr. Cady reviews the concepts of food allergy testing with IgG and IgE antibodies, traces the development of this body of knowledge from the 1960's, and reviews two illustrative cases.

  4. 4. Triadic model of thinking about diagnosis or treatment puzzles• PSYCHODYNAMIC - what makes a patient the way he/she is? – (what makes them act &/or respond as they do?)• FUNCTIONAL - what are some of the underlying physiologic processes which may be pathogenic?• IMMUNOLOGIC - what are the subtle manifestations of food allergies & sensitivities?
  5. 5. How not to get overwhelmed in this presentation:
  6. 6. Stanley E. Greben, MD• Some therapists stand out as uniquely effective.• Academics are no better.• “Every potential therapist must have a floor and a ceiling to his therapeutic capacity.”• Some gifted therapists are able to say why they succeed; others can’t explain it. “A great deal of what they do ‘right’ is intuitive.”“On Being Therapeutic” [Canadian Psychiatric AssociationJournal. Vol. 22(1977) 371-380.
  7. 7. Greben’s “Seven Habits”• Empathy & concern• Warmth• Interaction• Ability to arouse hope *• Expectation of improvement• “Not to despair”• Reliability & Friendliness *Requires clinical depth and breadth of knowledge
  8. 8. Psychodynamics 101• Patients can be vexing.• Diagnostic impasses provoke narcissistic angst.• Frustrated clinicians do not relate well with patients.• The more tools and capabilities one has, the greater the freedom, the options, and the ability to positively impact the patient.• The greater the success, the better the patient feels, the doctor feels, and the doctor-patient relationship feels.• The converse, worrisomely, also exists.

  18. 18. Food Allergies and ADHD in the Literature•Food allergies presumed to be related to ADHD • Get “THE THINKER” illustration•Before 1976 – No known relationship between FA and ADD•1976 – IgE reactivity + food allergies = decreased IQ•1985 – d/c of antigenic foods = ADHD improvement•1993 – more confirmation•1994 – some kids that got better on diet did NOT have IgEreactivity•2003 – evidence mounting for non-IgE sensitivities related to foodallergies]•2002 – 2011 Pelsser LM et al – SIX published papers (Europeanand Dutch literature, cf:•66 papers, at present – 8/19/2011
  19. 19. Millman, et al – the groundbreaking article• “Allergy & Learning Disabilities in Children” – Annals of Allergy, 1976 [36:3, 149-160.]• “The allergic tension-fatigue syndrome observed by Speer” – “A symptom complex accepted by many allergists.”• Food allergies established by scratch testing or intradermal injections• Positive correlation between [IgE] food allergies and IQ scores. – The more the food allergies, the lower the IQ scores.
  20. 20. Oligoantigenic diet (w/o testing)• “Controlled trial of oligoantigenic treatment in the Hyperkinetic Syndrome.” Egger et al. Lancet, March 9, 1985, 540-545.• No testing performed• Children empirically placed on restrictive diet. – Two meats, two carb sources, two fruits, one vegetable, water, calcium, vitamins.• No food allergy symptoms were provoked; ADHD improved.
  21. 21. The crossover study – no distinguishing between IgE and IgG• “Effects of a few foods diet on ADD.” Carter et al, Archives of Disease in Childhood, 1993;69:564-568.• “Few foods” elimination diet – 59 of 78 children improved.• “This trial indicates that diet can contribute to behavior disorders in children and that this effect can be shown in a double blind, placebo controlled trial.”• “The ways in which [this] diet worked remain unclear. Toxic pharmacological, or allergic mechanisms could be involved, and the physiological effects of different foods may vary.”
  22. 22. Profound cautions• “Effects of a few foods diet on ADD.” Carter et al, Archives of Disease in Childhood, 1993;69:564-568 (cont.)• “The treatment, as applied in this study, has disadvantages. It is a difficult and exacting regimen, which puts a considerable strain on the whole family. It is not yet clear whether modified diets can also be effective…. It may therefore be possible to devise a less restricted diet with similar levels of success.”• Cady impression: “Shooting in the dark is dangerous.”
  23. 23. The appearance of IgG• “Foods and additives are common causes of ADHD in children.” Boris, et. al. Annals of Allergy, vol.. 72, 1994, 462-468.• “DBPCF” - “double blind placebo controlled food challenge test”• 4/19 children who showed improvement with removal of offending foods were non- atopic.
  24. 24. “IgE and Non IgE Food Allergy”• Sabra, et al. Annals of Allergy, Asthma, and Immunology 2003;90 (Suppl 3)71-76.• “The gastrointestinal tract serves not only a nutritive function but also is a major immunologic organ. Although previously thought to be triggered primarily by an IgE mediated mechanism of injury, considerable evidence now suggests that non- IgE mechanisms may also be involved in the pathogenesis of FA (“food allergy”).
  25. 25. The patient: “Billy”• 8/1998 – 4 yo Eastern European adopted child – “ADD & behavioral problems, destructive.” – First 3 years of life in orphanage• Fam Psych Hx: – Dad – “substance induced paranoid psychosis” – Mother – “recurrent schizophrenic decompensations”

  45. 45. Gluten – one of the ultimate “bad boys” in food sensitivities • Headaches • Tearing up your gut • Depression • Suicide* – * Untreated celiac disease and attempted suicide. Lancet, September 1995. Pelligrino et al
  46. 46. Gluten and neurologic disease• “More recent studies have emphasized that a wider spectrum of neurologic syndromes may be the presenting extraintestinal manifestation of gluten sensitivity with or without intestinal pathology.” – -Bushara, KO. Neurologic presentation of celiac disease – Gastroenterology. 2005 Apr; 128(4 Suppl 1):592-7.
  47. 47. “UBO’s on MRI” – the gluten connection• 10 patients – had headaches. – MRI – UBO’s• 6 – unsteady, 4 gait ataxia• 90% response rate to gluten free diet.

  49. 49. Corvaglia, et al 1999• 3 adult patients found with undiagnosed/untreated celiac disease• Found by pediatricians who noted family history when child’s medical history obtained.• Celiac disease diagnosis was MADE in childhood, but diet was stopped due to no more GI symptoms.• In all three patients, depressive symptoms improved with gluten free diet.
  50. 50. Does it have to be celiac/gluten to mess up your head?-Migraine has high prevalence – 18%-Allergen-specific IgG in serum of patientsREFRACTORY TO TRADITIONAL TREATMENTexamined.-IgG antibodies obtained to 108 food allergens measured in56 patients with migraine and a control group.-Statistically significant differences found betweenmigraine group and control group in number of foodallergies. Answer: NO!-CONCLUSIONS: “ACCORDING TO THE RESULTSOBTAINED, serum IgG Antibodies to common foodshould be investigated in patients with migraine.”
  51. 51. What to be looking for… • Obvious GI problems • Chiro adjustments don’t “hold.” • Atypical presentations • KNOWN associations (autism) • Symptoms varying with diet • Excess ABX use (candida) • Lack of normal progression in treatment
  52. 52. Just one more: Joey - 6/28/11• 11 year old male 5th grader with dx of ADHD and Speech Apraxia; problems with reading, writing, oral expressive language, math, sequencing• Medical: – Hx of “lazy bowel” • “He doesn’t go more than once in two weeks.” • Dietary: likes cheese, chicken nuggets, ice cream, Coke, pizza. Used to like cottage cheese. – GI sxs refractory to pediatric interventions• Dx 1: ADD: 6/9 sxs of inattentiveness ON RX.• Dx 2:“Probable severe IgG food sensitivity with obvious stool retention problems”
  53. 53. Dairy IgG sensitivity suspected. Testing/Results:• Pediatrician ordered IgE RAST = NEGATIVE• 7/25/11 – no change. 2 BM’s in one month. – IgG Testing previously ordered. (Mom resistant and delayed due to cost. Finally done after this appt). RESULTS: • Milk – SEVERE • Mild: green peas, pinto beans, corn, garlic, tomato, wheat• 8/15/11 - constipation and fecal retention totally eliminated.
  54. 54. What I learned; what we can learn• Think about “the matrix” first.• Functional and immunologic inquiry and stabilization is a prerequisite for improvement in some cases. – (“You can’t tell by looking.”)• Psychodynamic errors (“blaming the patient”) can sabotage miraculous progress.• The human body has marvelous ability to heal itself naturally if given the breathing room to do so.
  55. 55. Diagnostic challenges & IgG food sensitivities - opportunities exist• “Tough cases”• Weird, multiple symptoms• Headaches• GI symptoms, food cravings, or both• ADHD and “bipolar” type symptoms• Processing issues (no pills available!)• Headaches resistant to standard chiropractic and medical tx• Fatigue, “brain fog”, temper fits
  56. 56. $3,000 vs. $5,500 – casket and funeral includedDon’t be a commodity. Acquaint yourself withdiagnostic testing available to you.
