S-adenosylmethionine is a relatively new anti-inflammatory drug with analgesic and anti-depressant effects. Efficacy of 800 mg orally administered s-adenosylmethionine daily versus placebo for six weeks was investigated in 44 patients with primary fibromyalgia in double-blind settings. Tender point score, isokinetic muscle strength, disease activity, subjective symptoms (visual analog scale), mood parameters and side effects were evaluated. Improvements were seen for clinical disease activity (P = 0.04), pain experienced during the last week (P = 0.002), fatigue (P = 0.02), morning stiffness (P = 0.03) and mood evaluated by Face Scale (P = 0.006) in the actively treated group compared to placebo. The tender point score, isokinetic muscle strength, mood evaluated by Beck Depression Inventory and side effects did not differ in the two treatment groups. S-adenosylmethionine has some beneficial effects on primary fibromyalgia and could be an important option in the treatment hereof.

Clinical features and psychological status determined by the Minnesota Multiphasic Personality Inventory (MMPI) in 103 patients with primary fibromyalgia syndrome (PFS) were analyzed by univariate and multivariate techniques to determine if clinical features were related to psychological status or were intrinsic to PFS per se. The central features of PFS, e.g., number of pain sites, number of tender points, fatigue, and poor sleep, were independent of psychological status. However, discriminant analysis identified 4 variables--patient-reported depression, anxiety, stress, and pain severity--which together predicted 3 MMPI subgroups with an accuracy of 55% (P less than 0.001); the only musculoskeletal feature--pain severity--alone provided an accuracy of only 34% (P greater than 0.05). These data suggest a new concept, that the central features of fibromyalgia are independent of the psychological status and are more likely related to the PFS itself. However, pain severity may be influenced by psychological factors.

Generalized tendomyopathy (GTM), or fibromyalgia, is a disorder characterized by diffuse pain in the musculoskeletal apparatus which usually begins at a single site, e.g., as low-back pain or cervical syndrome, and develops into generalized pain over months or years. It is accompanied by increased tenderness at characteristic tender points, although the pain threshold on the whole is reduced. In addition to the main symptoms (pain in the musculoskeletal system, tenderness at the tender points), autonomic and functional symptoms are almost invariably present and are often accompanied by pathological psychological findings such as neuroses and depression. To date, no reliable laboratory parameters or pathognomonic histological findings have been identified. The disorder affects primarily women, beginning around the age of 35 and reaching its peak during or after the menopause. It also affects young people and those over age 60, although it is much less common in these cases. Secondary forms are observed particularly in rheumatoid arthritis. The differential diagnosis must first distinguish primary GTM from the secondary forms. There must also be further differentiation between internal and psychiatric disorders and primary GTM. This can be achieved in many cases by careful clinical diagnosis, although a more complete examination is sometimes required.

Polymyalgia rheumatica is a syndrome that occurs in the elderly and is characterized by pain and stiffness involving the neck, the shoulder girdle, and the hip girdle. The aching should be present for greater than one month. Polymyalgia rheumatica may be more common than reported. The etiology remains unknown. There is generally little found pathologically in this disease. The physical examination is often not impressive. Synovitis may be a main contributing factor to many of the symptoms seen in patients with polymyalgia rheumatica. Symptoms often do not correlate with physical findings. Polymyalgia rheumatica must be differentiated from many conditions since the diagnosis remains entirely clinical. Osteoarthritis, flu syndromes, inflammatory myopathies, fibromyalgia, and depression all have features that may mimic polymyalgia rheumatica. Malignancies and infections may also be difficult to separate from polymyalgia rheumatica. Polymyalgia rheumatica may also be extremely difficult to differentiate from seronegative rheumatoid arthritis in patients older than 50 years. Although some patients with polymyalgia rheumatica have underlying giant cell arteritis, the majority apparently do not. The distinction between polymyalgia rheumatica and giant cell arteritis cannot be made on the basis of laboratory studies and relies solely on clinical symptoms and physical findings. Although nonsteroidal antiinflammatory medications may control symptoms in patients with mild disease, most patients with polymyalgia rheumatica require low-dose corticosteroids. The tapering schedule for the corticosteroids is contingent upon the response of symptoms and laboratory parameters. Polymyalgia rheumatica usually follows a benign course with almost complete response to an adequate treatment program. Recently, there have been several studies suggesting that the course of polymyalgia rheumatica may not be as short and simple as once proposed. Nevertheless, many patients may be completely weaned from corticosteroids. Other agents have been used in this disease, but for the most part their use remains somewhat controversial. Patients must be monitored carefully. Most patients do well, and treatment is effective.

Patients with chronic pain are often depressed, and antidepressants have been widely used in the treatment of these patients. Well controlled clinical studies have shown that antidepressants have analgesic effects, apparently independent of changes in mood, and in lower doses than used in the treatment of depression. Good results have been reported for several types of chronic pain, especially headache and facial pain, arthritis, fibromyalgia and neuralgias. In addition, antidepressants have also an indirect analgesic action by relieving a depressive condition associated with chronic pain.

The presence of clinical and electromyographic (EMG) features of neuromuscular hyperexcitability (NMHE) and of the commonly associated neurovegetative disturbances (NVD) were investigated in 49 patients with primary fibromyalgia (PF) and in a control group of 33 patients with rheumatoid arthritis (RA). At least two clinical features of NMHE were present in 39%, and at least three NVD in 63% of PF patients. In contrast, only 1 RA control had two NMHE features (p greater than 0.005) and three NVD (p less than 0.001). Moreover, a significant post-ischemic spontaneous EMG hyperactivity was observed in 11 PF patients, and in only 1 control with RA (p less than 0.05). Finally, in patients with PF the number of tender points were correlated with psychological tests for depression (p less than 0.02), and the number of NVD. The present study shows that in patients with PF there is a large prevalence of NMHE complaints and NVD. The potential underlying pathogenetic mechanisms are also discussed.

Prior psychologic and psychiatric studies in fibromyalgia are reviewed. Most of these reports had methodologic problems, but there is an association of depression with fibromyalgia described in the better studies. Hudson and Pope's hypothesis that there are 3 possible mechanisms to explain this association is examined and discussed in relation to current and future research in fibromyalgia.

Previous studies of psychological symptoms and psychiatric diagnoses in fibromyalgia have methodologic shortcomings. Although depressive and somatic symptoms are common, they are not more prominent than in other chronic medical conditions. There may be an association of depression with fibromyalgia, but this is not a causal one. The vast majority of patients with fibromyalgia do not meet criteria for a current psychiatric diagnosis.

Twenty patients with fibromyalgia syndrome and 20 patients with rheumatoid arthritis (RA) were assessed as outpatients over a 3 day period with respect to peak and trough levels of plasma cortisol, growth hormone, prolactin, ACTH and thyroid stimulating hormone. Patients with fibromyalgia syndrome had loss of diurnal variation in plasma cortisol (trough levels 347.3 +/- 254.7 vs 232.8 +/- 70.0 nmol/l, p less than 0.001) compared with RA patients. Thirty-five percent (7/20) of patients with fibromyalgia syndrome and only 5 percent (1/20) of those with RA exhibited abnormal dexamethasone suppression tests (p less than 0.001). No differences were noted in the diurnal variation of other hormones tested. Beck Depression Inventory scores were similar in both groups and no patient exhibited clinical evidence of depression. These data suggest alteration in the pituitary hypothalamic axis with respect to cortisol secretion in fibromyalgia syndrome, perhaps as a consequence of chronic pain.

Most previous psychologic and psychiatric studies of patients with fibromyalgia have utilized instruments that do not control for pain and therefore may be falsely interpreted as indicative of increased depression, hysteria, or hypochondriasis. Future studies must utilize psychiatric techniques that take into account a coexistent medical condition and such evaluation should include patients with varying levels of severity of fibromyalgia symptoms and utilization of health care.
