Developing Biomarkers for Fibromyalgia

Completed · Not applicable · Has a placebo group

Conditions studied: Fibromyalgia

In brief

The hypothesis of this study is that biological markers are present in the body that are good indicators of chronic pain. Eligible participants will be assessed at baseline and after receiving a series of acupuncture or "sham" acupuncture (something that resembles, but is not, active acupuncture) sessions. If the subject qualifies for the investigators' research and are subsequently enrolled in this study, they will be randomly assigned (like the flip of a coin) to one of these two groups. Acupuncture, as previously shown by this group, leads to improvements in both clinical and evoked pain associated with fibromyalgia. The study involves two magnetic resonance imaging (MRI) brain scans, one at the beginning and one at the end of the study. Another optional portion of the study would involve 2 PET (positron emission tomography) scans of the subject's brain, one at the beginning and one at the end of the study; this type of scan allows us to get more specific information about the subject's brain function during an acupuncture session.

• Daily use of narcotic pain-relievers
• History of substance abuse
• Simultaneous participation in other therapeutic trials
• Pregnant or breastfeeding
• Current severe psychiatric illness (e.g., schizophrenia, major depression with suicidal ideation)
• Condition that may make exposure to fMRI medically inadvisable

• Autoimmune or inflammatory disease (in addition to fibromyalgia) that causes pain (e.g., rheumatoid arthritis, systemic lupus erythematosus, inflammatory bowel disease)
• Having met the ACR criteria for FM
• Simultaneous participation in other therapeutic trials
• Pregnant or breastfeeding
• Current severe psychiatric illness (e.g., schizophrenia, major depression with suicidal ideation)
• Condition that may make exposure to fMRI medically inadvisable
• Any condition that may prevent satisfactory completion of the study protocol
• PET Exclusion Criteria:
• Meets any of the fMRI exclusion criteria
• Current major depression
