COMPLEX CHRONIC DISEASES PROGRAM Fibromyalgia and Chronic Pain in Related Disorders Clinical Protocol Date: Nov 15, 2015 Clinical Protocol: Fibromyalgia and Chronic Pain in Related Disorders PREAMBLE The recommendations below are supported by strong evidence (level A) unless stated otherwise We have added practical “tips” The drugs are presented in the order (more or less) to try them The actual order of use will depend on prior treatment, patient preference, etc. Look for “two fors” (drugs that benefit two or more problems) Provide patient with information/dose adjustment handout Given the different mechanisms of action, patients often end up on 2 or more drugs Patients with ME/CFS may need to be titrated more slowly, and may not tolerate higher doses of medications It is expected that physicians would educate themselves about these drugs beyond the outline provided below We have distinguished patient review, which can be done by nurse practitioner, from a physician review The treatments described below may occur one-on-one or in a group setting depending on resources 1. PATIENT EDUCATION Level A evidence Incorporated into multiple offerings (e.g., handouts, web-based resources) Incorporated into core group: Living with ME/CFS, FM, and related disorders “Family and Friends” evening session 2. PHYSICAL ACTIVITY Graded Exercise Therapy (GET) Level A evidence Offered in groups: Physical Activity Group Tai-Chi and mild Yoga o Suggested o Offerings in community rather than CCDP 3. SLEEP Sleep disturbance is a major component of FM and pain See sleep protocol for details 4. DIET Emerging evidence; some RCT data Offered in group setting o Topic specific “one-off” groups (one session) Diet 101 Low-Inflammatory Diet o Included in disease specific groups (3 – 5 sessions) E.g., IBS Group Page 1 COMPLEX CHRONIC DISEASES PROGRAM Fibromyalgia and Chronic Pain in Related Disorders Clinical Protocol Date: Nov 15, 2015 5. ALTERNATIVE AND COMPLEMENTARY THERAPIES Some agents have a strong theoretical rational and early evidence o Co-enzyme, D-Ribose 5 g, magnesium Malate, NADH, Vitamin D Other agents o Evidence under review 5.1 Co-enzyme Q 200 mg TID 5.2 D-Ribose 5 g TID 5.3 Magnesium Malate 250 mg QID 5.4 NADH 10 – 20 mg daily 5.5 Vitamin D 2000 IU daily 6.

ASSESS AND TREAT FOR COEXISTING ANXIETY AND MOOD DISORDERS Level A evidence Referral to psychiatrist for selected patients Page 8 COMPLEX CHRONIC DISEASES PROGRAM Fibromyalgia and Chronic Pain in Related Disorders Clinical Protocol Date: Nov 15, 2015 11. HORMONAL ISSUES Testing o TSH is part of the screening blood work for new patients o AM cortisol can be ordered as a second-line test o Patients requiring anything beyond this, should be referred to endocrinology Non-Addison adrenal insufficiency o Currently there is no evidence that patients who do not demonstrate adrenal insufficient by validated tests such as ACTH stimulation test, CRH stimulation test and Insulin Tolerance Test (ITT) would benefit from active glucocorticoid replacement. o The Clinical Advisory Committee believes that the potential harm would greatly outweigh any perceived benefit by patients. Patients with low TSH, low T3, and low T4 o These findings are analogous to those seen in “sick euthyroid” hospitalized patients. o Currently, there is no role for the administration of exogenous thyroxine to these patients. Extrapolating from this approach, CCDP patients with similar thyroid function test findings would similarly not be given thyroid replacement therapy. Growth Hormone o Lower levels of IGF-1 /GH have been reported in some patients with fibromyalgia. o Although growth hormone replacement has been explored in small series, the potential benefit of GH replacement long- term clearly is outweighed by the risks and cost. Hormone Replacement Therapy (HRT) for women o For Women, HRT is currently indicated for symptomatic management of perimenopausal symptoms. Ongoing use of HRT is associated with increased cardiovascular risks, venous thromboembolism, and breast cancer. o The use of HRT should not be routine in perimenopausal women without a further assessment of patient risks from these sex-hormone replacement. o Further referral to subspecialists is required for these patients. Androgen replacement in men o Androgen replacement therapy may be indicated for those with symptoms and who have a confirmed diagnosis of hypogonadism (decreased free testosterone levels below the normal values). o However, ongoing use of androgen replacement is similarly associated with the risk of cardiovascular disease and prostate disease. o The use of ART should not be routine in men with hypogonadism without a further assessment of patient risks from these sex-hormone replacement. o Further referral to subspecialists is required for these patients. Patient with diabetes insipidus-like symptoms o If patients are suspected to have diabetes insipidus based on a history of polyuria and polydipsia and the absence of diabetes of mellitus, they should be referred to an endocrinologist for consideration of a water deprivation test. o There is currently no logistic support at BCW’s to safely perform a water-deprivation test. Melatonin assessment o The Endocrinology panelist members are unaware on the implications of melatonin assessment on the health of patients.
