Diagnosing Fibromyalgia Clinical Signs & Symptoms
• Widespread Pain + 11/18 positive tender points
required. • Commonly associated are
– Fatigue – Sleep Dysfunction – Neurological Manifestations – Autonomic/Neuroendocrine Manifestations – Stiffness

Fibromyalgia Criteria
A pa?ent sa?sfies modified ACR 2010 fibromyalgia diagnos?c criteria if the following 3 condi?ons are met:
1. Widespread Pain Index ≥ 7 and Symptom
Severity Score ≥ 5. WPI Score _____ & SS Score ____
≥ 7 ≥ 5 or Widespread Pain Index between 3-‐6 and
Symptom Severity Score ≥ 9. WPI Score _____ & SS Score _____ 3-‐6 ≥ 9
Total Scores _____ 2. Symptoms have been at a similar level
for at least 3 months. 3. The pa?ent does not have a disorder
that would otherwise sufficiently explain the pain.

Questions: 2014 Conferences CFS Stanford & IACFS/ME
1. Is there objective evidence of objective biological abnormalities?
2. Could the abnormalities theoretically explain the symptoms
Do the abnormalities in fact correlate with the symptoms

2 Day VO2 Max Trials
• On day one, CFS/ME pa?ents perform similar to decondi?oned controls.
• On day two CFS/ME pa?ents have a 40% lower workload at their ven?latory threshold

Autonomic Function • Numerous studies have shown autonomic dysfunction in
ME/CFS (especially in younger patients including: – postural orthostatic hypotension – Abnormal response on Head up Tilt Table Test – increased heart rate at rest and with standing – decreased heart rate variability (HRV)
Boneva RS et al. Auton Neurosci 2007; 137(1-2): 94-101 Stewart JM et al. Pediatrics 1999; 103(1): 116-21. Hoad AM. QJ 2008; 101(12): 961-5.
19
Cardiac Function • Cardiac output is decreased, reduced blood volume
- correlates with physical symptoms. Peckerman A et al. Am J Med Sci 2003; 326(2): 55-60.
• 24 hour Holter EKGs are often abnormal with T wave flattening or inversion, tachycardia and premature contractions. Lerner AM et al. Virus Adaptation and Treatment 2010; 2: 47-57.
20
Muscle Metabolism • reduced intracellular concentrations of ATP. Wong R et al. Chest
1992; 102(6): 1716-22. • abnormalities in recovery of intramuscular pH following
standardized exercise. Jones D et al. Journal of Internal Medicine 2010; 267: 394-401.

21
Immune Dysfunction • decreased Natural Killer Cell function Klimas, N
• TH2 shifted immunity ↓ T suppressor lymphocyte subsets: CD8/38, CD8/11b • elevated cytokines

Genetic Profiles in FM & CFS • Spanish research: 1,500 patients with ME/CFS, FM
genetically analyzed using SNP technology - FM & ME can be genetically distinguished from from normal
Garcia-Fructuoso F. et al., Barcelona Spain, IACFS Conference, Ft. Lauderdale, Jan. 2007
• 620 ME/CFS with 3 generations of data in Salt Lake City Utah Population Data Base analyzed.
- ME significant numbers in first and second degree relatives of ME patients

7 Genetic Subtypes in ME/CFS 1. Cognitive, musculoskeletal, sleep, anxiety/depression 2. Musculoskeletal, pain, anxiety/depression 3. Mild 4. Cognitive 5. Musculoskeletal, gastrointestinal 6. Postexertional 7. Pain, infectious, musculoskeletal, sleep, neurological,
gastrointestinal, neurocognitive, anxiety/depression Kerr, Jonathan, et al. Seven genomic subtypes of CFS/ME: a detailed
analysis of gene networks and clinical phenotypes. J. Clin. Pathol. Dec. 2007. (50/75) (severity and clinical subsets)
Infections • ME/CFS can be triggered by numerous
infections including: Enteroviruses (especially Parvo B19), Epstein Barr Virus, Ross River Virus, Coxiella Hickie I. BMJ 2006; 333(7568): 575 (Australian prospective study). Kerr, J. J Gen Virol 2010; 91(Pt 4): 893-7.
• Associations have been found with: CMV, HHV6 Lerner AM Virus Adaptation and Treatment 2010; 2: 47-57.

Management Strategies 1. Improve symptoms,
functioning & quality of life 2. Secondary prevention of worsening
of chronic complex condition

Diet/Drugs
Sleep
32
EXERCISE/PACING/MOBILITY
Monitor via Activity Log: • Stay as active as possible WITHOUT
CRASHING • Increase slowly (10% RULE) • Strength train and prevent osteoporosis • Teach patients to trust own perceptions & build
gradually
Strong Women Stay Young – Miriam Nelson
33
Activity Log and Functional Capacity Scale
Scale from 0 to 10 Incorporates: • Energy rating • Symptom severity • Activity level
34
35
36
37
SUPPORT • listen non-judgmentally, share uncertainty,
review activity-pain logs • Clarify strengths, encourage self-care
strategies (home care, disability parking sticker)
• Reframe symptoms as early warning devices • Celebrate improvements, acknowledge
disappointments • Complete insurance forms • Psychological support – chronic illness stages
reactive depression/anxiety 38
39
PACING MIND-BODY MEDICINE
“Body, in this moment, what do I need?” Relaxation Response/meditation to increase
parasympathetic tone and reduce adrenal overstimulation (stop the adrenaline addiction & change brain function – brain neuroplasticity)
40
ENVIRONMENT
• Find patient stressors by using CH2OPD2 History/Home Assessment
• Avoid triggers: mold, cat/dog dander • Remove pollutants: dust mite protocol,
cleaning & personal care products, EMFs, toxic people both physical, emotional & contagious (virus infections)
41
DIET & NUTRITION
• EAT (Patients forget to eat) meals on wheels • Nutritious whole foods, no additives, avoid food
sensitivities/allergies • Drink 8 - 10 glasses H2O/day • Supplement - guidance of professional • Normal bowel movements – treat dysbiosis
think microbiota imbalance
42
SLEEP HYGEINE • Pace activities to avoid crashing
– tired and wired • Regular bedtime • No TV • Dark bedroom • Relaxation Response/Meditation • Calcium, Magnesium, Herbal teas,
Melatonin • Sleep Medication
43
Weed, Seed, and Feed Approach 1. Weed out known aggravators/stressors 2. Plant “SEEDS” of health: • S upport (self, family, social, medical, occupational, spiritual) • E xercise/pacing
• E nvironment
• D iet/Drugs
• S leep 3. Feed the SEEDS (nurture whatever helps)
44
Assessment Tools
• Visual Analogue Scale 1 - 10 • Patient Diaries (Activity Log & Functional
Capacity Scale) • Sleep and Pain Diaries – visual analogue
scales 1 – 10 • RAND/Short Form 36 Health Status
Inventory
45
Short Form-36 Functional Status Domains
• PF- Physical Functioning • RL-P- Role Limitations - Physical Health Problems • BP- Bodily Pain • GH- General Health Perceptions • E/F- Energy and Fatigue • SF- Social functioning • RL-E- Role Limitations Due to Personal or
Emotional Health Problems • EWB- Emotional Well-being Example: Environmental Health Clinic Patients, WCH, SF-36 Functional Status Lavergne R. et. al, Canadian Family Physician, 2009

SEID?????
• “Systemic Exertion Intolerance Disease” • Proposed as a new name for ME by the
Institute of Medicine • Focuses primarily on the aspect of fatigue
yet minimizes the other items in the Canadian Concensus Criteria
• Does not require other diagnoses to be excluded
