Pain. 2006 Feb 20; Authors: Usui C, Doi N, Nishioka M, Komatsu H, Yamamoto R, Ohkubo T, Ishizuka T, Shibata N, Hatta K, Miyazaki H, Nishioka K, Arai H The pathophysiology of fibromyalgia remains unknown. Several reports have recently suggested the novel concept that fibromyalgia is due to the central nervous system becoming hyper-responsive to a peripheral stimulus. The effect of electroconvulsive therapy (ECT) as pain remedication in cases of fibromyalgia without major depressive disorder was studied in a prospective trial lasting three months. All of the patients taking part in the study fulfilled the American College of Rheumatology diagnostic criteria for fibromyalgia. Technetium-99m ethyl cysteinate dimer single photon emission computed tomography was used to assess regional cerebral blood flow (rCBF) before and after a course of ECT. Pain assessment in the patients was undertaken by use of the visual analog scale (VAS) and by evaluation of tender points (TPs). Beck's depression inventory (BDI) was further used to assess depressive mood change in the patients. Our study clearly demonstrated that pain was significantly less severe after ECT, as indicated by the VAS scale for pain and the evaluation of TPs. A further notable observation was that thalamic blood flow was also improved. We conclude that a course of ECT produced notable improvements in both intractable severe pain associated with fibromyalgia and also in terms of thalamic blood flow.

Fibromyalgia syndrome: which antidepressant drug should we choose.
Related Articles Fibromyalgia syndrome: which antidepressant drug should we choose. Curr Pharm Des. 2006;12(1):3-9 Authors: Littlejohn GO, Guymer EK Fibromyalgia syndrome [FM] has core clinical features of widespread pain and widespread abnormal tenderness. The specific cause of the altered neurophysiology that underpins these clinical manifestations remains unclear. However, increased sensitisation of neural networks that relates to pain, as well as interacting mechanoreceptors, appear important targets for modulation by pharmacological agents. Further, many FM patients have emotional distress and some are depressed. Antidepressant agents have therapeutic benefits in FM. If depression is present antidepressant drugs will provide typical benefits to mood but not always to other key outcome measures, such as pain or tenderness. Selective serotonin receptor reuptake blockers are not as effective for overall FM improvement as drugs that block both serotonin and norepinephrine in a relatively balanced way. Thus tricyclic antidepressants will improve many important FM outcomes but are effective in only about 40 percent of individuals. Newer agents of this class, such as duloxetine and milnacipran, show improvement in key FM outcomes in about 60 percent of patients. Longer term studies will indicate the durability of these responses and the overall tolerance of the drugs. Any drug therapy will need to be integrated with appropriate education, exercise and attention to psychological modulatory factors to achieve best results.
