An increase of depressive symptoms in fibromyalgia patients has been noted in a number of studies. The etiologic significance of this finding remains, however, controversial. We suggest that a subgroup of patients with this symptom combination may be pragmatically classified as suffering from somatized depression. Clinical indicators such as a family history of depressive disorders, circadian disturbances, pronounced loss of appetite or libido, and chronic psychosocial stressors should be assessed and, if present, prompt the initiation of psychiatric evaluation and treatment including pharmaco- and psychotherapeutic modalities. Other psychiatric diseases arising in the differential diagnosis of fibromyalgia are discussed.

After elucidating the components and theory of neuroticism (N) as well as of psychosomatic complaints and their relationships to personality dimensions and to psychosomatic diseases, comparisons are performed between patients suffering from fibromyalgia syndrome (FMS) or related pain diseases with healthy subjects scoring high on personality dimensions related to neuroticism. FMS and pain patients score high on depression, anxiety, and experience of stress although questionnaire scores on depression are higher in subjects not exhibiting somatic features of the disease. High subjective pain sensitivity and low thresholds for pain perception are also common features in high N subjects and FMS patients. On the endocrinological level cortisol responses to challenge tests with CRH as well as prolactin responses to TRH are higher in FMS patients than in high N healthy subjects indicating an endocrinological difference. A common feature, however, is the lack of adaptability in the two groups, since neurotics are in particular characterized by a low capacity to shift their behavior from one state to the other (waking-sleeping, working-relaxing), to re-adapt to baseline levels after endocrinological or physiological stress responses, or to adjust to conditions of shift work. This is reflected by chronobiological disturbances in FMS patients and could also explain their maintainance of pain perception, because they are incapable of correcting conditioned pain-producing muscle tension.

Fibromyalgia syndrome (FMS) is recognizable syndrome characterized by chronic, diffuse pain, an absence of inflammatory or structural muscloskeletal abnormalities, and a range of symptoms that include fatigue, and sleep and mood disturbances. Physical examination and laboratory testing are unrevealing, except for the presence of pain on palpation of characteristic soft-tissue sites, the tender points. Despite the recognition of FMS by the World Health Organization, it remains a controversial condition and its existence as a distinct entity remains uncertain. However, the concept of FMS is a useful one, allowing many investigations to be avoided and appropriate advice on treatment to be given. FMS may overlap with symptoms of, and the patient further impaired by, anxiety and depression. The term FMS dose not imply causation and merely describes the most common symptoms. Many patients with chronic fatigue syndrome(CFS) fulfill the criteria of FMS and represent one end of a spectrum of presentation. Evidence for triggering viral infection and the lower level of serum acylcarnitine, observed in CFS patients, is lacking in the majority of patients with FMS. These findings are suggestive to be distinctively another disorders between FMS and CFS.

Polymyalgia rheumatica (PMR) is a disease of unknown etiology characterized by severe myalgia and stiffness at shoulder girdle and pelvic girdle muscles and by normal serum creatine kinase levels. Marked elevation of erythrocyte sedimentation rate, acute onset within two weeks, and appearance in the aged are also additional characteristics of PMR. Ten to 50% of PMR patients have a concomitant temporal arteritis (TA)(giant cell arteritis). For the differential diagnoses of PMR, rheumatoid arthritis, polymyositis, fibromyalgia, malignancies, infections and depression should be considered. PMR without TA is treatable successfully with small amount of steroids (15-20 mg/day of prednisolone). For the PMR patients with TA should be treated with large amount of steroids (40-60 mg/day of prednisolone) or steroid pulse therapy.

Neuropsychiatric diseases viewed as multifaceted expression of a dysfunctional brain in which atypical responses are evoked by various sensory inputs. Disease entities have traditionally been classified according to the predominant manifestation ( ) without regard to the overlapping features of many of the diseases (+/-). Thus, mild to moderate pain, mood, cognitive, and neurosomatic symptoms are frequently present in chronic fatigue syndrome (CFS) patients. Fibromyalgia syndrome (FMS) is listed as an example of a predominantly chronic pain syndrome. Affect (mood) disorders include depression (Depress.), anxiety, panic reactions, blunted affect, mania, etc. Schizophrenia (Schizo.) is listed as an example of a major cognitive psychosis. Autism as well as various forms of dementia would be included in this category. Irritable bowel syndrome (IBS) is an example of a neurosomatic disease.

Fibromyalgia is a chronic, painful musculoskeletal disorder characterized by widespread pain, pressure hyperalgesia, morning stiffness and by an increased incidence of depressive symptoms. The etiology, however, has remained elusive. The aim of the present study was to examine the inflammatory response system (IRS) in fibromyalgia. Serum interleukin-6 (IL-6), soluble IL-6 receptor (sIL-6R), sgp130, sIL-1R antagonist (IL-1RA) and sCD8 were determined in 33 healthy volunteers and in 21 fibromyalgia patients, classified according to the American College of Rheumatology criteria. Severity of illness was measured with several pain scales, dolorimetry and the Hamilton Depression Rating Scale (HDRS). Serum sgp130 was significantly higher and serum sCD8 significantly lower in fibromyalgia patients than in healthy volunteers. Serum sIL-6R and sIL-1RA were significantly higher in fibromyalgia patients with an increased HDRS score (> or = 16) than in normal volunteers and fibromyalgia patients with a HDRS score < 16. In fibromyalgia patients, an important part of the variance in sCD8 (50.3%) and IL-1RA (19.3%) could be explained by the HDRS score; 74.3% of the variance in sIL-6R was explained by the combined effects of pain symptoms and the HDRS score; and 25.9% of the variance in serum sgp130 was explained by stiffness. The results support the contention that pain and stiffness in fibromyalgia may be accompanied by a suppression of some aspects of the IRS and that the presence of clinically significant depressive symptoms in fibromyalgia is associated with some signs of IRS activation.

The symptomatology characterizing fibromyalgia (FM) comprises three systems: the musculoskeletal system with widespread muscular pain, neuroendocrine disorders, and psychological distress including depression. Though the most prominent symptom of FM is pain in defined points of the musculoskeletal system, the numerous other somatoform and psychological disorders suppose a common primary disturbance which we consider to originate within higher levels of the central nervous system. Recent studies of the entire endocrine profile of FM patients following a simultaneous challenge of the hypophysis with corticotropin-releasing hormone (CRH), thyrotropin-releasing hormone, growth hormone-releasing hormone, and luteinizing hormone-releasing hormone support the hypothesis that an elevated activity of CRH neurons determines not only many symptoms of FM but may also cause the deviations observed in the other hormonal axes. Hypothalamic CRH neurons thus may play a key role not only in "resetting" the various endocrine loops but possibly also nociceptive and psychological mechanisms as well.

'Toxicant-induced loss of tolerance' (or TILT) describes a two-step disease process in which (1) certain chemical exposures, e.g., indoor air contaminants, chemical spills, or pesticide applications, cause certain susceptible persons to lose their prior natural tolerance for common chemicals, foods, and drugs (initiation); (2) subsequently, previously tolerated exposures trigger symptoms. Responses may manifest as addictive or abdictive (avoidant) behaviors. In some affected individuals, overlapping responses to common chemical, food, and drug exposures, as well as habituation to recurrent exposures, may hide (mask) responses to particular triggers. Accumulating evidence suggests that this disease process might underlie a broad array of medical illnesses including chronic fatigue, fibromyalgia, migraine headaches, depression, asthma, the unexplained illnesses of Gulf War veterans, multiple chemical sensitivity, and attention deficit disorder.

Fibromyalgia (FM) is a nonarticular rheumatological syndrome associated with diverse clinical and psychological features. One of the major complaints in FM is reduced pain tolerance, especially in tender points (TP) for which patients derive significant benefit from nonsteroidal antiinflammatory drugs or corticosteroids. Patients with FM also have altered reactivity of the hypothalamic pituitary adrenal (HPA) axis where the predominant feature is reduced containment of the stress response system through diminished adrenocortical output and feedback resistance. Our results show that mud packs together with antidepressant treatment are able to influence the HPA axis, stimulating increased levels of adrenocorticotropic hormone, cortisol and beta-endorphin serum levels. The discharge of corticoids in the blood and the increase in beta-endorphin serum levels are followed by a reduction in pain symptoms, which is closely related to an improvement in disability, depression and quality of life. It seems that the synergic association between a pharmacological treatment (trazodone) and mud packs acts by helping the physiological responses to achieve homeostasis and to rebalance the stress response system. To clarify and optimize the effectiveness of this synergic association, studies involving a larger number of FM patients and a different pharmacological treatment are needed.

The aim of this study was to determine platelet alpha(2)-adrenergic receptor (alpha(2)-AR) binding sites in fibromyalgia both before and after treatment with sertraline or placebo. The maximum number of binding sites (B(max)) and their affinity (K(d)) for [(3)H]rauwolscine, a selective alpha(2)-AR antagonist, were measured in 13 normal volunteers and 22 fibromyalgia patients. Severity of illness was evaluated by means of the Hamilton Depression Rating Scale (HDRS) and dolorimetric assessments of tenderness at tender points. Fibromyalgia patients had repeated measurements of [(3)H]rauwolscine binding characteristics both before and after subchronic treatment with sertraline or placebo for 12 weeks. [(3)H]rauwolscine binding K(d) values were significantly higher in fibromyalgia patients than in normal volunteers. There were significant inverse correlations between [(3)H]rauwolscine binding K(d) values and duration of illness, age and lower energy. Significantly higher [(3)H]rauwolscine binding K(d) values were found in fibromyalgia patients in an early phase of illness (<3 years) than in fibromyalgia patients with a protracted illness (>3 years). Repeated administration of sertraline had no significant effects on [(3)H]rauwolscine binding B(max) or K(d) values. The results suggest that fibromyalgia and, in particular, fibromyalgia in an early phase of illness, is accompanied by lowered affinity of platelet alpha(2)-ARs.
