Abstract: BACKGROUND: Interdisciplinary guidelines for the definition, classification and diagnosis of chronic widespread pain (CWP) and fibromyalgia syndrome (FMS) were developed by collaboration of 10 German medical and psychological associations and 2 patient self-help organizations. METHODS: A systematic literature search was performed in the Cochrane Library (1993-12/2006). Medline (1980-2006), and Scopus (1980-12/2006). Levels of evidence were assigned according to the classification system of the Oxford Center for Evidence-Based Medicine. Grading of the strength of recommendation was done according to the German program for disease management guidelines. Standardized procedures to reach a consensus on recommendations were used. RESULTS: CWP is defined by the criteria of the American College of Rheumatology (ACR-strong consensus). FMS can be diagnosed for clinical purposes by symptom-based criteria (without tender point examination) as well as by the ACR criteria (strong consensus).

Abstract: BACKGROUND: A guideline for the treatment and diagnostic procedures for fibromyalgia syndrome (FMS) was developed in cooperation with 10 German medical and psychological associations and 2 patient self-help groups. METHODS: A systematic literature search including all controlled studies evaluating physiotherapy, exercise and strength training as well as physical therapies was performed in the Cochrane Collaboration Reviews (1993-12/2006), Medline (1980-12/2006), PsychInfo (1966-12/2006) and Scopus (1980-12/2006). Levels of evidence were assigned according to the classification system of the Oxford Centre for Evidence-Based Medicine. Grading of the strengths of recommendations was done according to the German program for disease management guidelines. Standardized procedures to reach a consensus on recommendations were used. RESULTS: Patient's information at first diagnosis of FMS is strongly recommended (grade A). Patient-centered communication is recommended (grade B). A stepwise treatment approach depending on the adapatation to restrictions in daily life and response to treatment options can be considered (grade C). CONCLUSIONS: The long-term treatment should be based on principles of basic psychosomatic care and shared decision making on treatment options.

Abstract: The fibromyalgia syndrome (FMS) is a chronic pain condition of the musculoskeletal system defined by criteria of the American College of Rheumatology in 1990. Despite this definition, etiology and pathogenesis of FMS are still unknown, and consequently the therapy aims mainly at relieving symptoms. The favourite hypothesis is a multietiological concept including genetic, central nervous, muscular, and psychological issues. This article focuses on current psychological aspects as to etiology, process of chronification, and therapy of FMS. Regarding etiology there are diverging hypotheses rather than a general agreement, e.g. specific personality traits, traumatic events, psychodynamic explanations on the basis of a depressive conflict, or the subsumption under somatoform disorders. However, psychological aspects are evident to influence the course and treatment of FMS. In the chronification process behavioural aspects like avoidance behaviour with subsequent physical impairment, attitudes towards subjective theories of illness and therapeutic options, social factors like effects on work, interpersonal conditioning, and coping strategies play an important role. Therapeutic options of FMS comprise exercise, drugs, and psychotherapy. An integrated approach combining these options, a sustainable doctor-patient relationship, and a continuous support of the patient seem to be beneficial.

Abstract: OBJECTIVE: The main objective of this review was to evaluate the role of psychosocial factors in the development of fibromyalgia syndrome. METHOD: Review of the literature concerning the influence of psychosocial factors. RESULTS: In fibromyalgia syndrome psychosocial factors are relevant at different etiological levels. They can be classified into predisposing, triggering and stabilising/"chronifying" factors. CONCLUSION: Due to the increasing knowledge about the influence of psychosocial factors for the development of fibromyalgia, the biomedical model has to be expanded to a biopsychosocial model. The biopsychosocial concept has an impact on the therapeutic approach. Strong evidence for the model is provided by the good results of interdisciplinary treatment studies.

Abstract: BACKGROUND: Therapy processes are complex dynamical systems where several variables are constantly interacting with each other. In general, the underlying mechanisms are difficult to assess. Our approach is to identify the dependency structure of relevant variables within the therapy process using interaction graphs. These are instruments for multivariate time series which are based on the analysis of partial spectral coherences. We used interaction graphs in order to investigate the therapy process of a multimodal therapy concept for fibromyalgia patients. Our main hypothesis was that self-efficacy plays a central role in the therapy process. METHODS: Patients kept an electronic diary for 13 weeks. Pain intensity, depression, sleep quality, anxiety and self-efficacy were assessed via visual analogue scales. The resulting multivariate time series were aggregated over individuals, and partial spectral coherences between each pair of the variables were calculated. From the partial coherences, interaction graphs were plotted. RESULTS: Within the resulting graphical model, self-efficacy was strongly related to pain intensity, depression and sleep quality. All other relations were substantially weaker. There was no direct relationship between pain intensity and sleep quality. CONCLUSIONS: The relations between two variables within the therapy process are mainly induced by self-efficacy. Interaction graphs can be used to pool time series data of several patients and thus to assess the common underlying dependency structure of a group of patients. The graphical representation is easily comprehensible and allows to distinguish between direct and indirect relationships.

Abstract: Fibromyalgia syndrome (FMS) is an exemplary condition of chronic widespread pain that is difficult to control and often leads to frustration and resignation on the part of both the patient and the doctor. Shared decision making (SDM) could be a means to facilitate doctor-patient interaction and might therefore influence therapeutic decisions taken. We conducted a prospective study to evaluate the effects of SDM with FMS patients. We developed a communication train-ing program for physicians and a computer-based information tool on FMS for patients.The study included 133 FMS patients. Intervention group I (IG I) was treated by communication-trained doctors and had access to a computer-based information tool on FMS,intervention group II (IG II) was treated by standard doctors and received the information tool, and the control group (CG) was treated by standard doctors and got no additional information. All three groups we-re offered the same evidence-based treatment options for FMS. Patients of the IGs were more willing to become involved in exercise, to enroll in integrated group therapy for FMS patients (IGTF), and to take analgesics. Patients of the CG preferred anti-depressants. More patients from IG II and CG opted for relaxation techniques. Patients in IG I and IG II choose significantly more therapeutic options than patients in the CG. SDM is one means to increase FMS patients' readiness for treatment. Especially the element of providing sufficient medical information seems to account for this effect. The readiness to enroll in physical activities, to take analgesics, and to participate in psychotherapeutic elements was most likely to be raised through SDM.

Abstract: BACKGROUND: This S3 guideline takes positions on currently contentious issues in the classification and treatment of fibromyalgia syndrome (FMS). METHODS: A panel of experts from 10 specialist societies and patients belonging to 2 patient self-help organizations reviewed a total of approximately 8000 publications. Recommendations were developed according to the suggested procedure for S3 guidelines and were then reviewed and approved by the boards of the participating specialist societies. The steering committee ensured that the literature review and the recommendations were kept up to date. RESULTS: Because this disorder is defined by its symptoms and signs, rather than by any consistently identifiable bodily lesion, the term "fibromyalgia syndrome" is a more appropriate designation for it than "fibromyalgia." FMS is defined by the criteria of the American College of Rheumatology and is classified as a functional somatic syndrome. FMS is diagnosed from the typical constellation of symptoms and by the exclusion of inflammatory and metabolic diseases that could cause the same symptoms. A stepwise treatment approach in which the patient and the physician decide jointly on the treatment options is recommended. The most strongly recommended forms of treatment are aerobic exercise, amitriptyline, cognitive behavioral therapy, and spa therapy. CONCLUSIONS: The guideline recommendations are intended to promote more effective treatment of this disorder.

Abstract: The guidelines aim to provide all professions involved in the treatment of fibromyalgia syndrome (FMS) a systematically developed basis for the diagnosis and therapy of FMS. Diagnostic criteria and empirically founded therapies are presented to reduce the currently insufficient medical care for FMS patients. Recommendations for a stepwise therapeutic approach are designed to improve the quality of medical care, the implementation of effective treatment options as well as reduction of the utilization of non-effective therapies and improvement of the patient-physician relationship. Recommendations on the coordination of medical care (inpatient and outpatient treatment by family physicians, medical specialists and other medical professions, care in emergency and rehabilitation hospitals) aim to reduce rivalry between medical societies and to promote an optimal use of resources. A patient version of the guidelines is aimed at improving patients' knowledge on the etiology and effective treatment options available thus promoting an effective self-management of patients.

Abstract: OBJECTIVE: Fibromyalgia syndrome (FMS) is a condition of chronic widespread pain that is difficult to control and is associated with strains in physician-patient interaction. Shared decision making (SDM) can be a potential solution to improve interaction. We evaluated the effects of an SDM intervention, including an SDM communication training program for physicians, in a randomized controlled trial with FMS patients. The main objective was to assess whether SDM improves the quality of physician-patient interaction from patients' perspective. METHODS: Patients were randomized to either an SDM group or an information-only group. The SDM group was treated by physicians trained in SDM communication and had access to a computer-based information package; the information-only group received only the information package and was treated by standard physicians. All patients were offered the same evidence-based treatment options for FMS. Patients were assessed with questionnaires on physician-patient interaction (main outcome criteria) and decisional processes. Physicians filled out a questionnaire on interaction difficulties. Assessment took place immediately after the initial consultation. RESULTS: Data from 85 FMS patients (44 in the SDM group and 41 in the information-only group) were analyzed. The mean age was 49.9 years (S.D.=10.2), and 91.8% of patients were female. The quality of physician-patient interaction was significantly higher in the SDM group than in the information-only group (P<.001). We found no differences in secondary outcome measures. CONCLUSIONS: SDM with FMS patients might be a possible means to achieve a positive quality of physician-patient interaction. A specific SDM communication training program teaches physicians to perform SDM and reduces frustration in patients.

Abstract: OBJECTIVE: Fibromyalgia syndrome (FMS) patients and their doctors frequently complain on interaction difficulties. We investigated the effects of a shared decision-making (SDM) intervention on physician-patient interaction and health outcome. METHODS: Sixty-seven FMS patients of an outpatient university setting that had been included in a randomized controlled trial were followed up. They were either treated in an SDM group or in an information group. Both groups saw a computer based information tool on FMS, but only the SDM group was treated by doctors which underwent a special SDM communication training. A comparison group of 44 FMS patients receiving treatment as usual was recruited in rheumatological practices. We assessed patients and their doctors using a combined qualitative and quantitative approach. Patients and doctors were followed-up after 3 months (T2) and after 1 year (T3). RESULTS: The significantly best quality of physician-patient interaction was reported by patients and doctors of the SDM group, followed by the information group. Coping had more often improved in the SDM group than in the information group. However directly health related outcome variables had not improved in any of the groups at T3. CONCLUSION: An SDM intervention can lead to an improved physician-patient relationship from the patients' and from the doctors' perspective. PRACTICE IMPLICATIONS: It should be considered to include SDM in standard care for FMS patients.

Abstract: OBJECTIVE: Assessment of the use of a computerized information-tool in the context of a shared decision-making process with chronic pain patients. METHODS: In the scope of a prospective and randomized study on shared decision-making with Fibromyalgia patients, a total of 75 patients had access to computer-based information about their illness. Fibromyalgia is a condition of chronic wide-spread pain, belonging to rheumatism, which mainly affects mature female patients. The majority of the patients in our study are female (93%) with an average age of 50 years. The computer-based information-tool provided the patients with detailed information about pathogenesis, typical symptoms, treatment options and prognosis. Six evaluative questions were posed to the participants concerning the assessment of the information presented, the handling of the programme, the need for an introduction to the programme, the quality of the layout and the assessment of the length of time spent in front of the computer and the assessment of the usefulness of such a tool in general practitioners' offices. Furthermore, psychological self-assessment questionnaires were filled out by the participants. RESULTS: The patients highly appreciate the possibility of using computer-based information-tools and endorse the implementation of such tools in general practitioners' offices. CONCLUSION: Computerized information leads to a better understanding of the illness and the treatment options on the part of the patient. PRACTICAL IMPLICATIONS: For further practical use it is crucial to provide an introduction to the handling of a computer to unskilled patients.

Abstract: BACKGROUND: Fibromyalgia syndrome (FM) is a disease with widespread chronic pain and many nonspecific symptoms. Hyaluronic acid (HA) is a disputed marker for the diagnosis of FM. The aim of the study is to clarify the discrepant results reported so far. METHODS: Serum concentrations of HA were measured with a radiometric assay (Pharmacia & Upjohn, Sweden) in 41 patients with FM (38 females), 48 with arthritis (35 females) and 31 control subjects (28 females). Correlations of HA levels with clinical parameters (duration of disease, age, gender, medication) and scores of disease severity (e.g. depression and pain) were calculated. If appropriate, partial correlations and analysis of covariance adjusted for confounding variables (e.g. age) were used. RESULTS: HA levels were confirmed to be age-related in the whole study group (r(s) = 0.54; P < 0.001) and each subgroup. Association between HA levels and gender, drug therapy, clinical or psychometric data could not be demonstrated in patients suffering from FM. Analyzing all study participants, HA levels were correlated with the pain disability index (PDI) (r(tau) = 0.27; P < 0.02) and, in arthritis patients only, with duration of disease (r(tau) = 0.82; P < 0.001). Moreover, analysis of covariance revealed that patients with FM had normal HA values as compared with control subjects and only patients with arthritis had significantly higher levels than both other groups. CONCLUSIONS: The present study with a quite large cohort including patients with arthritis and FM demonstrates that serum levels of HA in FM are neither elevated nor associated with any relevant clinical data of this disease and, therefore, have no diagnostic or prognostic value in Germans.

Abstract: AIM: The aim of the present study was to evaluate to what extent the orthostatic dysregulation of FMS patients can be attributed primarily to reduced baroreceptor-mediated activation of the sympathetic nervous system and whether a hyporeactive sympathetic nervous system can also be confirmed for mental stress. PATIENTS AND METHODS: A total of 28 patients with primary FMS were examined and compared with 15 healthy subjects. Diagnostic investigations of the autonomic nervous system were based on measuring HRV in frequency range and assessing spontaneous baroreflex sensitivity (sBRS) under mental stress and passive orthostatism. RESULTS: Both under orthostatic and mental stress FMS patients exhibited reduced activation of the sympathetic nervous system as measured by the spectral power of HRV in the low-frequency range and the mean arterial blood pressure or heart rate. The present study provided no indications for dysregulation of sBRS. CONCLUSION: The results obtained confirm the hypothesis of a hyporeactive stress system in FMS patients for both peripherally and centrally mediated stimulation of the sympathetic nervous system.

Abstract: Conditions affecting the musculoskeletal system are the cause of approximately 25% of absenteeism from work. Fibromyalgia syndrome is an exemplary condition of chronic widespread pain which most physicians consider difficult to manage. The physician-patient relationship is burdened with resignation and frustration on both sides. Initial agreement regarding the aims of treatment is rare. The patient's active involvement in the decision making process is expected to improve the physician-patient relationship. One aspect of this shared decision making process is the evaluation and possibly modification of treatment decisions. In the present study 39 consultations of physicians who had undergone special communication training were examined as to whether these physicians actually exercised the option of revising their treatment decisions. In 87.2% of the consultations the therapy decisions were modified within three months after the first encounter. Patients considered to be "difficult" were less likely to modify their decisions. The shared decision making process usually takes more than one consultation.

Abstract: OBJECTIVE: Fibromyalgia syndrome (FMS) is a condition of chronic widespread pain. In its process of chronification psychosocial factors play an important role. A multimodal treatment including integrated group therapy has been proved to be effective. Yet little attention has been paid so far to the exact sequence of changes and interrelation between psychosocial factors, functional capacity, and level of pain under integrated group therapy for FMS patients. METHODS: One FMS patient was exemplarily monitored with an electronic diary over 13 weeks while undergoing integrated group therapy. On a daily basis we assessed the level of pain, functional capacity, and other disease-related variables (anxiety, depression, quality of sleep, self-efficacy) via visual analog scales. By the means of multivariate time series analysis the timing of changes in psychosocial factors and their effects on perceived functional capacity was identified. RESULTS: Under integrated group therapy all assessed variables gradually changed in the predicted way. Pain, depression, anxiety could be reduced, whereas self-efficacy, quality of sleep, and functional capacity improved. 71% of the variance could be explained by the multiple regression model. Self-efficacy was, beside pain intensity and depression, an important predictor for functional capacity on the same day. High self-efficacy correlated negatively with the level of functional capacity 3 days later. CONCLUSION: Integrated group therapy proved to be effective. Self-efficacy played an important role regarding the improvement of functional capacity. Depicting the exact timing of changes in the assessed variables helped to detect patterns of influence and indicate directions for further treatment.

Abstract: BACKGROUND: The purpose of the study was to examine the pain related health care utilization in patients with fibromyalgia syndrome. METHODS: In a multicenter study six rheumatological hospitals associated in the rheumatological center of Heidelberg participated. All consecutive patients which fulfilled the ACR-criteria of fibromyalgia were assessed. Data about pain and related treatments were available from n=259 patients. RESULTS: Patients suffered from chronic generalized pain on average for 5 years before being diagnosed as fibromyalgia. In most of the cases longlasting localized pain symptoms preceeded generalized pain. The spectrum of pain related treatments seems to be wide and arbitrary: 87% took questionable or excessive medication. 86% had some form of physiotherapy and 41% already experienced psychological treatment. 28% of the patients consulted dental surgeons including teeth extraction and 20% underwent multiple orthopaedic surgery. A mean of five different health care professionals were consulted regarding the pain problem. Treatment satisfaction rated by the patients was lowest with pharmacological and highest with psychological treatment and physiotherapy. CONCLUSIONS: The health care-seeking behavior of fibromyalgia-patients seems to be characterized by a multitude of different treatment attempts. Treatment was often invasive and focused on localized symptoms rather than on the generalized pain syndrome. An early confirmation of the diagnosis and a more evidence based treatment is strongly indicated.

Abstract: Self-efficacy is assumed to account for significant variance in the treatment outcome of chronic pain patients. The aim of this study was to provide a German version of an approved measure of disease-related self-efficacy in fibromyalgia (FM) patients which assesses treatment outcomes and specific differences compared to other pain patients. The 8-item short-form of the arthritis self-efficacy scale was translated into German (ASES-D) and administered to 148 FM patients and 53 patients with rheumatoid arthritis (RA). In addition, similar cognitive constructs (locus of control, optimism/pessimism, and general self-efficacy) and disease-related variables (pain, functioning, depression, and coping) were assessed. The instrument was further applied to 43 FM patients who underwent interdisciplinary group therapy. Validation methods consisted of correlation, principal component analysis and difference testing between the disease groups. The instrument met good psychometric properties. Evidence for construct validity was provided. Self-efficacy was sensitive to changes and could be used in predicting the treatment outcome in FM patients. The German short-form ASES-D is a further step toward an internationally comparable assessment of disease-related self-efficacy in FM.

Abstract: OBJECTIVE: To determine the prevalence and potential diagnostic relevance of autoantibodies against serotonin, thromboplastin, and ganglioside Gm1 in patients with fibromyalgia syndrome (FM). METHODS: Sera from 203 patients with FM and 64 pain-free control subjects were analyzed with enzyme immunoassays. Clinical and psychometric data of the patients were analyzed for the presence or absence of autoantibodies. RESULTS: Compared with control subjects patients with FM had a significantly higher prevalence of autoantibodies against serotonin (20% vs 5%; p = 0.003) and thromboplastin (43% vs 9%; p < 0.001), but not against ganglioside Gm1 (15% vs 9%; p = 0.301). Differences in autoantibody prevalence between controls and FM patients were not related to age or sex. No association was found between autoantibody pattern and clinical or psychometric data, e.g., pain, depression, pain related anxiety, and activities of daily living. CONCLUSION: There is an elevated prevalence of antibodies against serotonin and thromboplastin in patients with FM. The pathophysiological significance of this finding is unknown. Calculation of positive predictive values of antiserotonin antibodies shows that measurement of these antibodies has no diagnostic relevance.
