This study explored the significance of anxiety and depression in quality of life, functional disability and lifestyle among fibromyalgia patients. Functional disability was defined by subjective work ability and activity-related discomfort. Lifestyle reflected habits of physical activity, regularity of meals, smoking and patterns of drinking coffee and alcohol. Members of two county divisions of fibromyalgia patients (N = 322) were investigated. Owing to colinearity between anxiety and depression scores, extreme groups were defined according to high vs. low anxiety and depression scores. Two-thirds of the initial sample were excluded by this approach which permitted a 2 x 2 factorial split-plot MANCOVA for the assessment of main effects and interaction of anxiety and depression upon quality of life, functional disability and lifestyle. Main effects of anxiety and depression were significant for index scores on activity-related discomforts, subjective work ability and quality of life, whereas depression was also significantly associated with regularity of meals. Anxiety and depression interacted to yield relatively high consumption of coffee and cigarettes among the anxious and depressed subgroup, and this effect emerged only after the elimination of confounding effects of age and duration of the fibromyalgia disease.

In this article, a number of hormones and neuropeptides regulating pain, well-being and stress are shown to play important roles in the association between stress perception and nociception. Derangements in the stress axis may be induced by a variety of factors in which life events, personality, psychosocial circumstances and gender all may contribute. When such derangements are long-lasting, probably several neuroendocrine modifications are induced, giving rise to many of the symptoms seen in chronic pain syndromes including fibromyalgia.

The aim of this study was to investigate the presence of different mycoplasmal species in blood samples from patients with chronic fatigue syndrome and/or fibromyalgia syndrome. Previously, more than 60% of patients with chronic fatigue syndrome/fibromyalgia syndrome were found to have mycoplasmal blood infections, such as Mycoplasma fermentans infection. In this study, patients with chronic fatigue syndrome/fibromyalgia syndrome were examined for multiple mycoplasmal infections in their blood. A total of 91 patients diagnosed with chronic fatigue syndrome/fibromyalgia syndrome and with a positive test for any mycoplasmal infection were investigated for the presence of Mycoplasma fermentans, Mycoplasma pneumoniae, Mycoplasma hominis and Mycoplasma penetrans in blood using forensic polymerase chain reaction. Among these mycoplasma-positive patients, infections were detected with Mycoplasma pneumoniae (54/91), Mycoplasma fermentans (44/91), Mycoplasma hominis (28/91) and Mycoplasma penetrans (18/91). Multiple mycoplasmal infections were found in 48 of 91 patients, with double infections being detected in 30.8% and triple infections in 22%, but only when one of the species was Mycoplasma pneumoniae or Mycoplasma fermentans. Patients infected with more than one mycoplasmal species generally had a longer history of illness, suggesting that they may have contracted additional mycoplasmal infections with time.

The prevalence and disability rate of rheumatic diseases are increasing. It seems that non-medical causes play an important role in the morbidity, disability and mortality of these patients. Efforts to reduce their impact are extremely important. Patient education is thought to be one way to limit disability in rheumatic diseases and to achieve an improvement in quality of life. In this chapter, we review the influence of non-medical causes of morbidity on disease outcome, some basic aspects of education and the evidence of the effectiveness of patient education in diseases such as ankylosing spondylitis, systemic lupus erythematosus, rheumatoid arthritis and fibromyalgia syndrome.

Complementary and alternative medicine (CAM) has become an important subject for rheumatologists. This article is an attempt to provide an introduction to this subject. It will provide definitions of, and define the prevalence of, CAM. The emphasis of the article is on evaluating the efficacy of CAM treatment modalities. This is achieved by referring to systematic reviews of clinical trials of acupuncture for low back pain, osteo-arthritis, fibromyalgia, inflammatory rheumatoid disease and neck pain. Further areas addressed in this way are herbal remedies, fish oil and glucosamine. Moreover, massage therapy and spinal manipulation for back pain are discussed. The final sections of this review deal with the safety and cost of CAM. It is concluded that, in view of the popularity of CAM with rheumatological patients, rigorous research into CAM is the best way forward.

Rheumatologists grapple in daily practice with many controversial syndromes including fibromyalgia, late whiplash syndrome, chronic fatigue syndrome, Gulf War syndrome, the adverse outcomes of silicon breast implants and so on. For decades, much of the debate surrounding, and the approach to these controversial syndromes has centred on a model creating two camps-organic versus non-organic. While each camp has its support, this model seems to have failed in achieving the desired understanding of these syndromes, most particularly in offering the rheumatologist a practical and coherent approach to effective treatment. This chapter will thus introduce the biopsychosocial model, its elements, its advantages over the traditional model and the practical application of this model. Examples will be given of how rheumatologists can approach the treatment of these syndromes through patient education and the implementation of a change in illness behaviour.

The aims of the present study were to examine serotonergic markers, i.e. [3H]paroxetine binding characteristics and the availability of plasma tryptophan, the precursor of serotonin (5-HT), and the plasma concentrations of the branched chain amino acids (BCAAs), valine, leucine and isoleucine, in fibromyalgia. The [3H]paroxetine binding characteristics, B(max) and K(d) values, and tryptophan and the competing amino acids (CAA), known to compete for the same cerebral uptake mechanism (i.e. valine, leucine, isoleucine, phenylalanine and tyrosine), were determined in fibromyalgia patients and normal controls. There were no significant differences in the [3H]paroxetine binding characteristics (B(max) and K(d)) between fibromyalgia and control subjects. There were no significant differences in plasma tryptophan or the tryptophan/CAA ratio between fibromyalgia patients and normal controls. In the fibromyalgia patients, there were no significant correlations between [3H]paroxetine binding characteristics or the availability of tryptophan and myalgic or depressive symptoms. Patients with fibromyalgia had significantly lower plasma concentrations of the three BCAAs (valine, leucine and isoleucine) and phenylalanine than normal controls. It is hypothesized that the relative deficiency in the BCAAs may play a role in the pathophysiology of fibromyalgia, since the BCAAs supply energy to the muscle and regulate protein synthesis in the muscles. A supplemental trial with BCAAs in fibromyalgia appears to be justified.

Chronic fatigue syndrome (CFS) is a poorly understood disease characterized by mental and physical fatigue, most often observed in young white females. Muscle pain at rest, exacerbated by exercise, is a common symptom. Although a specific defect in muscle metabolism has not been clearly defined, yet several studies report altered oxidative metabolism. In this study, we detected oxidative damage to DNA and lipids in muscle specimens of CFS patients as compared to age-matched controls, as well as increased activity of the antioxidant enzymes catalase, glutathione peroxidase, and transferase, and increases in total glutathione plasma levels. From these results we hypothesize that in CFS there is oxidative stress in muscle, which results in an increase in antioxidant defenses. Furthermore, in muscle membranes, fluidity and fatty acid composition are significantly different in specimens from CFS patients as compared to controls and to patients suffering from fibromyalgia. These data support an organic origin of CFS, in which muscle suffers oxidative damage.

The brain and the immune system are the two major adaptive systems of the body. During an immune response the brain and the immune system "talk to each other" and this process is essential for maintaining homeostasis. Two major pathway systems are involved in this cross-talk: the hypothalamic-pituitary-adrenal (HPA) axis and the sympathetic nervous system (SNS). This overview focuses on the role of SNS in neuroimmune interactions, an area that has received much less attention than the role of HPA axis. Evidence accumulated over the last 20 years suggests that norepinephrine (NE) fulfills the criteria for neurotransmitter/neuromodulator in lymphoid organs. Thus, primary and secondary lymphoid organs receive extensive sympathetic/noradrenergic innervation. Under stimulation, NE is released from the sympathetic nerve terminals in these organs, and the target immune cells express adrenoreceptors. Through stimulation of these receptors, locally released NE, or circulating catecholamines such as epinephrine, affect lymphocyte traffic, circulation, and proliferation, and modulate cytokine production and the functional activity of different lymphoid cells. Although there exists substantial sympathetic innervation in the bone marrow, and particularly in the thymus and mucosal tissues, our knowledge about the effect of the sympathetic neural input on hematopoiesis, thymocyte development, and mucosal immunity is extremely modest. In addition, recent evidence is discussed that NE and epinephrine, through stimulation of the beta(2)-adrenoreceptor-cAMP-protein kinase A pathway, inhibit the production of type 1/proinflammatory cytokines, such as interleukin (IL-12), tumor necrosis factor-alpha, and interferon-gamma by antigen-presenting cells and T helper (Th) 1 cells, whereas they stimulate the production of type 2/anti-inflammatory cytokines such as IL-10 and transforming growth factor-beta. Through this mechanism, systemically, endogenous catecholamines may cause a selective suppression of Th1 responses and cellular immunity, and a Th2 shift toward dominance of humoral immunity. On the other hand, in certain local responses, and under certain conditions, catecholamines may actually boost regional immune responses, through induction of IL-1, tumor necrosis factor-alpha, and primarily IL-8 production. Thus, the activation of SNS during an immune response might be aimed to localize the inflammatory response, through induction of neutrophil accumulation and stimulation of more specific humoral immune responses, although systemically it may suppress Th1 responses, and, thus protect the organism from the detrimental effects of proinflammatory cytokines and other products of activated macrophages. The above-mentioned immunomodulatory effects of catecholamines and the role of SNS are also discussed in the context of their clinical implication in certain infections, major injury and sepsis, autoimmunity, chronic pain and fatigue syndromes, and tumor growth. Finally, the pharmacological manipulation of the sympathetic-immune interface is reviewed with focus on new therapeutic strategies using selective alpha(2)- and beta(2)-adrenoreceptor agonists and antagonists and inhibitors of phosphodiesterase type IV in the treatment of experimental models of autoimmune diseases, fibromyalgia, and chronic fatigue syndrome.

This study was undertaken to translate and adapt the Fibromyalgia Impact Questionnaire (FIQ) into the Turkish language and investigate its validity and reliability for Turkish female fibromyalgia (FM) patients. After translation into Turkish, we administered the FIQ and Health Assessment Questionnaire (HAQ) to 51 women with fibromyalgia. As well as sociodemographic characteristics, the severity of relevant clinical symptoms, e.g., pain intensity, fatigue, and sleep disturbance, were assessed by visual analog scales. A tender point score (TPS) was calculated from tender points conducted by thumb palpation. Test-retest reliability, internal consistency, and concurrent and construct validities of FIQ were evaluated. Test-retest reliability and internal consistency were good at 0.81 and 0.72, respectively. Correlation between FIQ and HAQ scores was 0.43, which was low but statistically significant. Significant moderate correlations were obtained between the FIQ items and severity of clinical symptoms (0.63-0.77), except TPS, 0.31. The FIQ is a reliable and valid instrument for measuring functional disability in Turkish female FM patients.
