Fibromyalgia is a chronic, musculoskeletal pain condition that predominately affects women. Although fibromyalgia is common and associated with substantial morbidity and disability, there are no US Food and Drug Administration-approved treatments. However, progress has been made in identifying pharmacological and non-pharmacological treatments for fibromyalgia. Recent pharmacological treatment studies have focused on selective serotonin and norepinephrine reuptake inhibitors, which enhance serotonin and norepinephrine neurotransmission in the descending pain pathways and lack many of the adverse side effects associated with tricyclic medications. Promising results have also been reported for medications that bind to the alpha2delta subunit of voltage-gated calcium channels, resulting in decreased calcium influx at nerve terminals and subsequent reduction in the release of several neurotransmitters thought to play a role in pain processing. There is also evidence to support exercise, cognitive behavioral therapy, education, and social support in the management of fibromyalgia. It is likely that many patients would benefit from combinations of pharmacological and non-pharmacological treatments, but more study is needed.

The term 'Ca2+ channel alpha2delta ligands' has recently been applied to an evolving drug class that includes gabapentin (Neurontin) and pregabalin (Lyrica), and reflects significant progress over the past decade in elucidating the mechanism of action of these drugs: a novel, specific action at one of the subunits constituting voltage-sensitive Ca2+ channels. Binding of these ligands to the alpha2delta subunit is considered to explain their usefulness in treating several clinical disorders, including epilepsy, pain from diabetic neuropathy, postherpetic neuralgia and fibromyalgia, and generalized anxiety disorder. The evidence indicates a relationship between alpha2delta subunit binding and the modulation of processes that subserve neurotransmission. This modulation is characterized by a reduction of the excessive neurotransmitter release that is observed in certain neurological and psychiatric disorders.

Vitamin D inadequacy is pandemic among rehabilitation patients in both inpatient and outpatient settings. Male and female patients of all ages and ethnic backgrounds are affected. Vitamin D deficiency causes osteopenia, precipitates and exacerbates osteoporosis, causes the painful bone disease osteomalacia, and worsens proximal muscle strength and postural sway. Vitamin D inadequacy can be prevented by sensible sun exposure and adequate dietary intake with supplementation. Vitamin D status is determined by measurement of serum 25-hydroxyvitamin D. The recommended healthful serum level is between 30 and 60 ng/mL. 25-Hydroxyvitamin D levels of >30 ng/mL are sufficient to suppress parathyroid hormone production and to maximize the efficiency of dietary calcium absorption from the small intestine. This can be accomplished by ingesting 1000 IU of vitamin D(3) per day, or by taking 50,000 IU of vitamin D(2) every 2 weeks. Vitamin D toxicity is observed when 25-hydroxyvitamin D levels exceed 150 ng/mL. Identification and treatment of vitamin D deficiency reduces the risk of vertebral and nonvertebral fractures by improving bone health and musculoskeletal function. Vitamin D deficiency and osteomalacia should be considered in the differential diagnosis of patients with musculoskeletal pain, fibromyalgia, chronic fatigue syndrome, or myositis. There is a need for better education of health professionals and the general public regarding the optimization of vitamin D status in the care of rehabilitation patients.

Fibromyalgia syndrome (FMS) affects 2-10% of the adult population in industrial countries and although it is associated with substantial morbidity and disability, treatment options are unsatisfactory. The rapid growth of trials for FMS in recent years has resulted in new, evidence-based approaches to medical treatment. This review focuses on the randomized, controlled studies of newer pharmacological options for FMS, such as selective serotonin/norepinephrine reuptake inhibitors (duloxetine, milnacipran), inhibitors of voltage-gated calcium channels (pregabalin, gabapentin), dopamine-2/3-receptor agonists (pramipexole, ropirinole), sedative-hypnotic agents (sodium oxybate, modafinil, dronabinol), 5-HT3 antagonists (tropisetron) and others (tramadol, dextromethorphan, olanzapine).

Vitamin D(3) (cholecalciferol) sufficiency is essential for maximising bone health. Vitamin D enhances intestinal absorption of calcium and phosphorus. The major source of vitamin D for both children and adults is exposure of the skin to sunlight. Season, latitude, skin pigmentation, sunscreen use, clothing and aging can dramatically influence the synthesis of vitamin D in the skin. Very few foods naturally contain vitamin D or are fortified with vitamin D. Serum 25-hydroxyvitamin D [25(OH)D; calcifediol] is the best measure of vitamin D status. Vitamin D deficiency [as defined by a serum 25(OH)D level of <50 nmol/L (<20 ng/mL)] is pandemic. This deficiency is very prevalent in osteoporotic patients. Vitamin D deficiency causes osteopenia, osteoporosis and osteomalacia, increasing the risk of fracture. Unlike osteoporosis, which is a painless disease, osteomalacia causes aching bone pain that is often misdiagnosed as fibromyalgia or chronic pain syndrome or is simply dismissed as depression. Vitamin D deficiency causes muscle weakness, increasing the risk of falls and fractures, and should be aggressively treated with pharmacological doses of vitamin D. Vitamin D sufficiency can be sustained by sensible sun exposure or ingesting at least 800-1000 IU of vitamin D(3) daily. Patients being treated for osteoporosis should be adequately supplemented with calcium and vitamin D to maximise the benefit of treatment.

Synthesized in 1990 as an anticonvulsant agent, pregabalin was designed as a lipophilic gamma-aminobutyric acid (GABA) analog substituted at the 3'-position in order to facilitate diffusion across the blood-brain barrier. It is an alpha2delta1 ligand that binds to, and modulates, voltage-gated calcium channels. This modulation is characterized by a reduction of the excessive neurotransmitter release that is observed in certain neurologic and psychotic disorders. Pregabalin has analgetic, anticonvulsant, and anxiolytic activity and has demonstrated efficacy in the management of neuropathic pain associated with diabetic peripheral neuropathy, postherpetic neuralgia, and as adjuvant therapy for adult patients with partial onset seizures. Pregabalin was significantly more effective than placebo for the treatment of generalized anxiety disorder as well as of fibromyalgia and was well tolerated by most of the patients.

Fibromyalgia syndrome (FMS) is characterized by widespread musculoskeletal pain. It has negative effects on quality of life and has been poorly investigated in specific populations. Our aim was to determine the prevalence of FMS in Brazilian hemodialysis (HD) patients and to investigate its effects on the quality of life. We investigated 311 patients on HD who were submitted to physical examination towards the classification of FMS. All subjects from FMS and control groups were submitted to laboratorial investigation and completed questionnaires of quality of life. The prevalence of FMS was 3.9%, which was close to that of the general population. Most patients were females and from non-Caucasian races. No difference between FMS and control groups was observed regarding race, dialysis adequacy, nutritional status and level of schooling. Ionized calcium was higher in the FMS group than in the control group. There was no association between FMS and secondary hyperparathyroidism. On the other hand, FMS was associated with worse quality of life, depression and anxiety. In conclusion, the prevalence of FMS in HD patients was similar to that of the general population. It was associated with decreasing quality of life in HD patients, in addition to higher degrees of depression and anxiety. No laboratory tests could identify FMS patients on HD. Fibromyalgia syndrome subsequently follows without a well-established mechanism of pathogenesis, and seems to be due to multifactorial causes. Its true impact on the quality of life of HD patients deserves more attention by nephrologists.

The therapy of pain caused by rheumatic diseases above all must take into consideration the cause of the pain. In rheumatoid arthritis, especially in the early stages, inflammation is the primary cause of the pain. The pain decreases the inflammation subsides following the administration of non-steroidal anti-inflammatory drugs (NSAIDs), or corticosteroids, if necessary. The so-called disease modifying anti-rheumatic drugs do not influence the inflammation or consequently, the pain directly, but rather through mechanisms before the local joint process some of which are not exactly known. In later stages of the progressive joint degeneration the NSAIDs only have a limited effect regarding the inhibition of inflammation. In osteoarthrosis, in which the pain is caused by a secondary inflammation and increasingly by capsular, muscular and tendon involvement, the pain is only treated by NSAIDs in active inflammatory stages; otherwise, the treatment is physical activity and medication. In degenerative and static disorders of the spine the pain is caused predominantly by muscular bracing. Therefore, physical and especially gymnastic therapy play a major role. Whether muscle relaxants have an effect on muscle bracing is doubtful. If there is pressure on the ligaments and, in cases of vertebral dislocation with overstraining of the vertebral joints, therapy with local injections is indicated. The pain in osteoporosis is also predominantly muscular and must be treated accordingly. Above all, high doses of calcium and calcitonin are effective analgesics. Moreover, fluoride also acts as an analgesic once the osteoporosis has stabilized. In most cases fibromyalgia, which is mostly of a psychosomatic nature, cannot be influenced by medical therapy. Instead repeated attempts at treatment help to make the affliction chronic with neurotic fixation. Also, as a rule, myotonolytic and tranquilizing substances are not effective.

Fibroblast growth factor 23 (FGF23), a recently discovered phosphaturic substance playing a key role in genetic and oncogenic phosphate diabetes, is involved in the physiological regulation of phosphate metabolism. Moderate idiopathic phosphate diabetes (IPD) leading to male osteoporosis and diffuse pain resembling fibromyalgia has been described. The aim of our study was to define the role of FGF23 in the mechanism of IPD. The study concerned 29 patients with IPD, mean age 53 +/- 11 years, of whom 72% were men. Fifteen subjects without bone disease and with normal serum phosphate and calcium levels were used as controls. Phosphate diabetes was confirmed by phosphate reabsorption level <85% and phosphate reabsorption threshold (TmPO4/GFR) <0.83. Known causes of phosphate diabetes were excluded. Fasting level of FGF23, serum phosphate, 1-25(OH)2D3, and parathyroid hormone were measured in patients and compared with FGF23 and serum phosphate in healthy controls. Spinal and hip bone mineral density (BMD) were measured by osteodensitometry. Sixteen of 29 patients had diffuse pain, 10 had osteoporosis according to the World Health Organization criteria, and 11 had osteopenia. Serum phosphate was significantly lower in patients than in controls, but FGF23 levels did not differ. Compared to patients with normal bone status, patients with osteopenia and osteoporosis had significantly decreased FGF23 levels, whereas serum phosphate was identical in the two groups. In all patients, serum phosphate and FGF23 were positively correlated and FGF23 and 1-25(OH)2D3 were negatively correlated. FGF23 seems not be a cause of IPD, and the FGF23/phosphate/1-25(OH)2D3 axis appeared to be functional.

Fibromyalgia (FM) is a common, chronic pain disorder with unknown etiology, characterized by widespread musculoskeletal pain and tenderness, and accompanied by several other symptoms such as sleep disturbance, fatigue, and mood disorders. Pregabalin is the first drug approved for the treatment of FM. Pregabalin has analgesic, anticonvulsant, and anxiolytic activity and has earlier demonstrated efficacy in the management of neuropathic pain associated with diabetic peripheral neuropathy, postherpetic neuralgia, and as adjuvant therapy for adult patients with partial onset seizures. Pregabalin, a lipophilic gamma-aminobutyric acid (GABA) analog, is alpha(2)delta-1 ligand that binds to, and modulates, voltage-gated calcium channels. This modulation is characterized by a reduction of the excessive neurotransmitter release that is observed in certain neurological and psychotic disorders. Several randomized, double-blind, placebo-controlled studies have demonstrated that pregabalin has been effective in pain management, improving sleep quality and fatigue, as well as in several domains of health related quality of life. Because of mild to moderate adverse effects it can be considered a well-tolerated therapy for FM.
