Breakthrough Diet Therapy for IBS, Migraines & Fibromyalgia using

MRT testing and the LEAP DIET protocol Jan Patenaude, RD, CLT

Learning Objectives

• Describe 3 or more types of adverse food reactions

• Understand how diet can play a role in the development of IBS, migraines & fibromyalgia • Discuss Mediator Release Testing as an

effective tool for dietitians to develop an oligoantigenic diet

Case Presentation - Diane

• 24 year old female diagnosed with D-IBS (diarrhea predominant) and migraine headaches. Also severe joint pain and sinusitis.

• Blood Pressure elevated: 122/86 • Symptom Survey scored 119 points

GUT IMMUNOLOGY

Immune Food Allergy/Sensitivity

• Ingestion - GALT reacts

• Recognition - Antigen as invader • Defense – WBC, antibodies, immune

components mount defense

• Warfare – Chemical Mediators released • Proinflammatory and proalgesic

mediators released

ADVERSE

REACTIONS

Immunologic

(ALLERGY or

SENSITIVITY)

Non-Immunologic (INTOLERANCE)

IMMUNE REACTIONS ALLERGIES SENSITIVITIES TYPE 3 TYPE 1 Antibody mediated (IgE) TYPE 4 Antibody Mediated (IgG, IgM) Cell Mediated HISTAMINE CAFFEINE -CHEMICALS SIBO -Dysbiosis LECTINS LACTOSE FODMAPS NON-IMMUNE

Food Allergy – Type I

• IgE • Mast Cells

• Usually immediate • Can result in anaphylaxis • 2-4% of population

• Peanut, diary, egg, fish, wheat, nuts, soy

IgE - Testing

IgE Allergy – Rast/Elisa Testing – RAST- Radio Allergo Sorbent Test – ELISA - Enzyme Linked Immuno

Sorbent Assay

• Negative test does not mean “food is safe”

• About 60% accuracy. • No chemicals tested

IgE – Testing

Skin Prick Testing (SPT/Scratch Test) • Accurate for environmental allergies • Not accurate for food allergies – SKIN vs

Gut Immune System

• Positive result is only 30-50% predictive • If intradermal, may increase sensitivity

Food reactions do not correlate

to IgE allergy in the diagnosis

of food related GI symptoms

Gut. 1996 Jul;39(1):130-5 Conclusions: Adult patients - food induced GI symptoms, DBPCFC, there were no indications of IgE mediated allergy to the relevant foods, suggesting other mechanisms in adults than in children.

Food Sensitivity – Type III

• Non-IgE

• Immune Complex Mediated • Delayed Response – 2-8 hours • IgG may be protective

• IgG may be due to consumption • No food Chemicals

• Testing: IgG ELISA – poor reliability

Food elimination based

on IgG antibodies in IBS

• 150 Patients

• Avoid IgG reactive foods vs. sham diet

• Outcome measures - SS scores. • RESULTS: 12 weeks - 10% greater

reduction in scores than the sham diet • 26% in fully compliant patients

Gut. 2004 Oct;53(10):1459-64.

IgG Testing for Food Allergy

Not Recommended

• Many samples show +IgG

without corresponding clinical

symptoms

• Lack of Controlled Studies

• IgG indicates repeat exposure to

food

Allergo J 2009; 4:267

Food Sensitivity – Type IV

• Non-IgE/IgG immune response

• Involves different mechanisms,

different cells, different mediators

• Much more common -

15-20%

• Testing: Alcat - older technology

• MRT-Substantial technological

improvements

Type IV Hypersensitivity Reaction

• Foods and food additives trigger non-allergic (non-IgE mediated) immune reaction causing mediator release by immunologic cells Histamine, Serotonin Prostaglandins Leukotrienes Cytokines Dopamine

Physiologic effects of released pro-inflammatory and pro-algesic mediators

• IBS: Inflammation, smooth muscle contraction, diarrhea, cramping, visceral hypersensitivity • Migraine: vasoconstriction, vasodilatation,

inflammation, WBC activation, pain receptor activation

• Others: muscle and joint aches and pain, fatigue, anxiety, depression, acne, insomnia, mood swings, food cravings, seizures, autism .

An overview on immune

system and migraine

• Authors state that although pathogenesis of migraine is still unclear . . .

• Cytokines considered pain mediators in neurovascular inflammation.

• Cytokines may be a cause of migraine pain • High levels of chemokines could stimulate the

activation of trigeminal nerves, the release of mediators, and then cause inflammation.

Eur Rev Med Pharmacol Sci. 2007 Jul-Aug;11(4):245-8

Cytokines play a role in fibromyalgia: a hypothesis and pilot study

• 56 FM patients compared with controls • Cytokines and cytokine-related molecules were

measured

• Conclusion: Patients with FM had increased levels of IL-8 which promotes sympathetic pain and IL-6 which induces hyperalgesia, fatigue and depression, it is hypothesized that they may play a role in modulating FM symptoms.

Rheumatology 2001; 40: 743-749

Other Conditions That May Be

Associated with Food Sensitivity

• Celiac disease • Ulcerative colitis • Crohn’s disease • GERD • Asthma • Migraines • Tinnitus • Depression • Rhinitis/Sinusitis • Secretory otitis media • ADHD • Urticaria • Angio-edema • Rheumatologic disorders • Atopy

Typical Diet Recommendations

for IBS

• Increase Dietary Fiber Intake • Eat Small Frequent Meals • Eat Low Fat Content Meals • Drink Lots of Water • Avoid Gas Forming Foods • Avoid Spicy Foods

Avoid FOOD TRIGGERS

Typical Diet Recommendations

for Migraine

• Limit Pressor Amines • Limit dietary histamine

• Avoid dehydration-drink plenty of water • Avoid hypoglycemia

• Eat lower fat meals • Eliminate caffeine • Avoid MSG

Avoid FOOD TRIGGERS

Typical Recommendations

for Fibromyalgia

• Stress Management

• Eliminate white flour and sugar • Exercise

• Get plenty of rest • Eliminate/avoid caffeine • Healthy Diet

Challenges Historically Faced

When Identifying Reactive Foods

25

Unlike allergies, food sensitivity reactions are: • Dose dependent

• Delayed onset (up to 72 hours) • Multiple foods can cause symptoms • Single elimination trials are useless

• NO universal bad food - very patient specific

Mediator Release Testing:

Eliminating

The

Guesswork

Mediator Release Test (MRT)

• 120 foods and 30 chemicals are tested • Each sample analyzed and compared to the

patients own control samples

• Checked for anymediator release from cells • Cells should

not react!

Pasula et al, Amer. Clin. Lab., May 99; 18(4): 16-18 Pasula et al, Amer. Clin. Lab., Oct 99; 18(4): 14-15

• Common end-point of ANY Cellular Reaction can be measured

• Degree of reactivity determined by mediator release from cells • Degree of reactivity

can be quantified

Mediator Release Test (MRT)

LEAP Oligoantigenic Diet

• Patient specific • Week 1: 20-25 least

reactive of the Non-reactive foods • Weeks 2-4: Slowly

introduce new Non-reactive foods • Test for oral

tolerance

LEAP Oligoantigenic Diet

• Patients avoid all Moderately Reactive and Reactive foods • In time, they are

advised to rotate all foods

• Add ‘untested’ foods and test for oral tolerance

(6)

Symptom Survey

• Filled out by patient Prior to Testing 7-10 days on diet 4 weeks 2-3 months • Evaluate and document current symptoms • Easy visual of patient progress

Cytokine Profile in D-IBS

• 40 year old male with lifelong IBS • On LEAP diet for > 1 yr and symptom free • Baseline plasma cytokine profile obtained • Patient then violated LEAP diet and consumed

known reactive foods

• Typical GI and systemic symptoms quickly recurred • Second plasma cytokine profile obtained

Evidence Based Medicine

Per JADA March 2005

Evidence-based practice uses: • The best available evidence

• The results of peer-reviewed studies • And, when science is lacking, expert

opinion and experience
