OBJECTIVE: Studies of bone turnover in fibromyalgia (FM) have, to date, shown conflicting results. Although most patients with FM are women, only a few investigations have paid attention to the changes of sex hormones in FM. Moreover, FM is often viewed as a stress related disorder, and abnormalities of the hypothalamic-pituitary-adrenal (HPA) axis have been found in FM. The aim of the study was to assess bone turnover using serum osteocalcin and CTx in patients with FM and study correlation between bone turnover parameters and parathormon and hormones of the HPA axis.METHODS: A total of 81 subjects participated in this study: 41 healthy volunteers and 40 patients with FM. Serum osteocalcin, crosslaps (C-telopeptide: CTx), parathyroid hormone (PTH), testosterone, estrogen, prolactin, FSH, and LH were measured. The mean age of the study population was 49.5 (7.6) years (32-69) and the mean disease duration was 8.1 (12.0) years (4.5-30.7).RESULTS: No difference between patients and controls were observed in serum calcium, phosphorus, creatinine, albumin, osteocalcin, testosterone, and urinary calcium. Patients had lower serum levels of CTx, estrogen, PTH and prolactin than controls and higher serum levels of LH and FSH with a significant statistical difference. No significant statistical correlation was observed between intensity of pain and fatigue and bone turnover parameters and PTH or hormones of the HPA axis. CONCLUSION:Our study showed that patients with FM had low bone resorption and normal bone formation compared to a control group. This was not related to several hormonal perturbations observed in these patients and may reflect functional impairment as suggested in previous studies.

OBJECTIVE: To evaluate function and disability in patients with fibromyalgia before and after participation in a functionally oriented, multidisciplinary, 8-wk treatment program. DESIGN: A total of 23 patients who met American College of Rheumatology criteria for the diagnosis of fibromyalgia were enrolled in the study. Outcome measures included: range of motion, 6-min walk test, a modified Fibromyalgia Impact Questionnaire, a modified SF-36 Physical Functioning Scale, and the Fibromyalgia Health Assessment Questionnaire. Pretreatment and posttreatment scores were analyzed using paired t tests. RESULTS: All subjects completed the program, and there were no reported injuries. Three subjects failed to complete the survey instruments at the conclusion of the study. Intention to treat analysis including these subjects was carried out but did not significantly change results. For the remaining subjects (n = 20), a significant improvement was found on the Physical Functioning Scale (P = 0.01). Trends toward improvement on the Fibromyalgia Impact Questionnaire (P = 0.40) and Fibromyalgia Health Assessment Questionnaire (P = 0.14) were seen but did not achieve statistical significance. Range of motion testing revealed significant improvements in lumbar spine extension (P < 0.001), straight-leg raise (P < 0.001), cervical spine flexion (P < 0.01), cervical spine rotation (P < 0.05), and cervical spine side bending (P < 0.05). Distance traveled during the 6-min walk test increased significantly (P < 0.01), whereas perceived exertion as measured by the Borg scale did not change. There were no injuries or other adverse consequences of the program. CONCLUSIONS: This study utilized multiple functional outcome measures to demonstrate improved function and decreased disability in patients with fibromyalgia. Our patients reported significantly improved physical function after participation in the 8-wk intensive multidisciplinary treatment program. This progressive, functionally based exercise training program was well tolerated by all participants and outlines an effective exercise prescription for patients with fibromyalgia. Fibromyalgia patients in this study responded favorably to a treatment program that focused on function instead of pain.

Clinical potential of milnacipran, a serotonin and norepinephrine reuptake inhibitor, in pain.
Curr Opin Investig Drugs. 2006 Jul;7(7):637-42
Authors: Leo RJ, Brooks VL
Milnacipran is a serotonin (5-HT) and norepinephrine (NE) reuptake inhibitor currently available for use as an antidepressant in several countries. Phase III clinical trials are currently underway to assess its potential role in the treatment of fibromyalgia syndrome, and in pursuit of US Food and Drug Administration approval for this indication. Evidence has accumulated suggesting that in animal models, milnacipran may exert pain-mitigating influences involving NE- and 5-HT-related processes at supraspinal, spinal and peripheral levels of pain transmission. Preliminary evidence suggests that milnacipran may be useful in mitigating pain and fatigue associated with fibromyalgia. However, its role in addressing comorbidities associated with fibromyalgia, including visceral pain and migraine, has yet to be investigated.
