Abstract: OBJECTIVE: To develop evidence-based recommendations for the management of fibromyalgia syndrome. METHODS: A multidisciplinary task force was formed representing 11 European countries. The design of the study, including search strategy, participants, interventions, outcome measures, data collection and analytical method, was defined at the outset. A systematic review was undertaken with the keywords "fibromyalgia", "treatment or management" and "trial". Studies were excluded if they did not utilise the American College of Rheumatology classification criteria, were not clinical trials, or included patients with chronic fatigue syndrome or myalgic encephalomyelitis. Primary outcome measures were change in pain assessed by visual analogue scale and fibromyalgia impact questionnaire. The quality of the studies was categorised based on randomisation, blinding and allocation concealment. Only the highest quality studies were used to base recommendations on. When there was insufficient evidence from the literature, a Delphi process was used to provide basis for recommendation. RESULTS: 146 studies were eligible for the review. 39 pharmacological intervention studies and 59 non-pharmacological were included in the final recommendation summary tables once those of a lower quality or with insufficient data were separated. The categories of treatment identified were antidepressants, analgesics, and "other pharmacological" and exercise, cognitive behavioural therapy, education, dietary interventions and "other non-pharmacological". In many studies sample size was small and the quality of the study was insufficient for strong recommendations to be made. CONCLUSIONS: Nine recommendations for the management of fibromyalgia syndrome were developed using a systematic review and expert consensus.

Abstract: Do patients with fibromyalgia (FM) have reduced muscular strength? We examined 22 articles and conclude from the results of these that FM patients have reduced muscular strength in their hands and quadriceps. The material also suggests generalised reduced muscular strength. However, the studies have several methodological shortcomings and future studies should be carefully designed with respect to patients as well as the control group and should be larger. To avoid CNS influence from e.g. fatigue and pain, muscular electro-stimulation may be used to ensure that the actual maximal muscular strength is also measured.

Abstract: Chronic pain is very common in all European countries, with musculoskeletal problems predominating. About 1% of the adult population develops a syndrome of chronic muscle pain, fibromyalgia (FMS), characterized by multiple tender points, back or neck pain, and a number of associated problems from other organs, including a high frequency of fatigue. Evidence points to central sensitization as an important neurophysiological aberration in the development of FMS. Importantly, these neurological changes may result from inadequately treated chronic focal pain problems such as osteoarthritis or myofascial pain. It is important for health professionals to be aware of this syndrome and to diagnose the patients to avoid a steady increase in diagnostic tests. On the other hand, patients with chronic widespread pain have an increased risk of developing malignancies, and new or changed symptoms should be diagnosed even in FMS. In rheumatology practice it is especially important to be aware of the existence of FMS in association with immune inflammatory diseases, most commonly lupus and rheumatoid arthritis. Differential diagnoses are other causes of chronic pain, e.g. thyroid disease. The costs of this syndrome are substantial due to loss of working capability and direct expenses of medication and health-system usage. Fibromyalgia patients need recognition of their pain syndrome if they are to comply with treatment. Lack of empathy and understanding by healthcare professionals often leads to patient frustration and inappropriate illness behavior, often associated with some exaggeration of symptoms in an effort to gain some legitimacy for their problem. FMS is multifaceted, and treatment consists of both medical interventions, with emphasis on agents acting on the central nervous system, and physical exercises.

Abstract: OBJECTIVE: To use a new immunologic assay to evaluate antipolymer antibody (APA) levels among women with silicone breast implants (SBIs). METHODS: Women (n = 186) were identified through Danish population-based registers and categorized into six groups defined by prior breast surgery (silicone breast implantation/breast reduction/no breast surgery) and by the presence or absence of a prior hospital diagnosis of soft-tissue rheumatism (muscular rheumatism, ICD-8 codes 717.90 and 717.99). The women underwent blood tests, including an APA test, a clinical examination, and an interview focusing on rheumatic complaints. Blood samples were tested blindly. The severity of rheumatic symptoms/signs was scored from 1 (none) to 5 (severe) based on the clinical examination and interview. RESULTS: Women with SBIs did not have higher levels of APA than women without SBIs. The majority of women with SBIs had mild rheumatic complaints, and the severity of their symptoms was not related to APA levels. Among women who had previously been hospitalized because of soft-tissue rheumatism, there were more fibromyalgia cases, and their symptoms were more severe compared with those women without prior soft-tissue rheumatism; however, APA levels were not higher among these women. There was a significant difference in APA measurements resulting from between-kit variation (p less 0.01). CONCLUSIONS: Our data did not demonstrate higher APA levels among women with SBIs compared with controls. The large variation observed between the individual plates in the APA test should be evaluated in future studies.

Abstract: OBJECTIVE: To investigate the effect of an antiviral compound, valacyclovir, on pain and tenderness in patients with the fibromyalgia (FM) syndrome. METHODS: Sixty patients were randomized into a double blind, placebo controlled 6 week trial. Primary outcome was pain intensity change (on visual analog scale). Secondary outcome measures were tender points (myalgic score) and Fibromyalgia Impact Questionnaire (FIQ). RESULTS: Fifty-two patients completed the study. The numbers of dropouts due to adverse events were equal in valacyclovir (2) and placebo (2) groups. The effect of valacyclovir on pain and tenderness and FIQ did not differ from placebo. CONCLUSION: Valacyclovir cannot be recommended as a therapy for FM at this point.

Abstract: OBJECTIVE: To test the hypothesis that fibromyalgia (FM) patients with reduced lower extremity strength are more symptomatic and tender than FM patients with normal muscle strength. METHODS: A total of 840 FM patients and 122 healthy subjects were evaluated between 1998 and 2005. All of the patients completed version 1 of the Fibromyalgia Impact Questionnaire (FIQ) and were assessed for tender points and knee muscle strength. All subjects underwent bilateral isokinetic knee muscle strength testing in flexion and extension. Normative knee muscle strength values were calculated from the healthy subjects, and the FM cohort was divided in 2 groups: 1) patients with normal muscle strength and 2) patients with low muscle strength (2 SDs below normal). The clinical characteristics of these 2 groups were compared. RESULTS: Significantly reduced knee muscle strength was found in 52% of the patients. There were no clinically significant differences between patients with low versus normal muscle strength. There were no clinically significant correlations between total FIQ score, tender point count, and muscle strength. Only 4.6% of the FIQ scores and 5.1% of the tender point counts were explained by muscle strength. CONCLUSION: Significantly reduced knee muscle strength was found in more than half of the patients. Patients with subnormal muscle strength were not more symptomatic or tender than patients with normal muscle strength. There were no clinically significant correlations between FIQ, tender point count, and muscle strength; therefore, reduced knee muscle strength appears to be a common objective abnormality in FM that is independent of measurements of disease activity. The implication of this finding in regard to the clinical assessment of FM needs further study.

Abstract: OBJECTIVE: To assess the metabolism of collagen in fibromyalgia (FM) patients, and to compare the occurrence of collagen metabolism markers to the severity of FM symptoms. METHODS: Morning urine was collected from 27 FM women fulfilling the American College of Rheumatology (ACR) criteria for FM, and from seven controls. FM patients completed the Fibromyalgia Impact Questionnaire (FIQ). Bone mineral density (BMD), isokinetic muscle strength in knee and elbow, and hand-grip strength were measured. Urinary concentrations of collagen type I cross-linked C-telopeptide (CTX-I) and collagen type II cross-linked C-telopeptide (CTX-II) were determined by enzyme-linked immunosorbent assay (ELISA). Pyridinoline (Pyd) and deoxypyridinoline (Dpd) were determined by liquid chromatography, and hydroxyproline (Hyp) by spectrophotometry. All concentration data were normalized to creatinine. RESULTS: Mean values in the FM group and the control group, respectively, were: urinary CTX-I 246.8 and 337.5 microg/mmol (p = 0.060); CTX-II 110.4 and 185.1 ng/mmol (p = 0.035); Pyd 56.1 and 52.3 nmol/mmol (NS); Dpd 15.1 and 14.0 nmol/mmol (NS); Pyd : Dpd ratio 4.05 and 3.96 (NS); Hyp 26.1 and 21.1 micromol/mmol (NS). Significant inverse correlations were seen between CTX-I and the intensity of fatigue, and between CTX-II and anxiety. An inverse correlation between CTX-I and muscle strength was apparent, but relied on extreme values from one patient, and no significant correlation was found between CTX-I or CTX-II and tender points or BMD in the FM group. CONCLUSIONS: Low urinary concentrations of CTX-II and CTX-I and normal levels of Pyd and Dpd were found in FM, but their relationship to the intensity of FM symptoms was unclear.

Abstract: AIM: To look at the effect of physiotherapy as part of the multidisciplinary treatment of torture victims. METHODS: Monitoring of an extended, personally designed, multidisciplinary treatment of 21 torture victims, earlier exposed to both physical and psychological torture, over nine months with assessment of outcome. The physiotherapy comprised elements such as massage, exercise on land, balance training and stimulation of proprioception, all aiming at regaining body awareness. Effect of treatment was measured using the fibrositis index. Non-parametric statistics using the Wilcoxon test was applied. RESULTS: Prior to treatment the median score of the fibrositis index was 15 points (range 2-34). After nine months of multidisciplinary treatment the median score of the fibrositis index was 2 points (range 0-3415). This decrease in experienced muscle pain was statistically significant (p<0,0001). CONCLUSION: A high percentage of the torture victims in our study suffered from fibromyalgia prior to treatment. A multidisciplinary treatment involving individualised physiotherapy and psychotherapy had a significant effect on musculoskeletal pain in torture victims. Following nine months of treatment, only one torture victim in our study could be classified as suffering from fibromyalgia when applying the fibrositis index.

Abstract: OBJECTIVE: To analyze whether fibromyalgia (FM) and FM-like symptoms are related to an increased incidence of cancer. METHODS: We identified 1361 patients referred on suspicion of FM in the period 1984-99 from hospital records. Following the American College of Rheumatology (ACR) criteria, patients were divided into subgroups with and without confirmed FM. The cohort was followed to the end of 1999 and linked to the files of the Danish Cancer Register. Site-specific standardized incidence ratios (SIR) were calculated. RESULTS: We found no association between FM and cancer in 1132 female patients with confirmed FM at our institution (SIR 1.2, 95% CI 0.8-1.8). In 106 women referred for muscle pain and/or tenderness who did not meet the criteria for FM, an increased overall SIR was observed (SIR 2.5, 95% CI 1.2-4.6), with increased risk for breast cancer (SIR 4.8, 95% CI 1.6-11.3) and lymphatic and hematological cancers (SIR 10.6, 95% CI 1.2-38.2). There were 4 lung cancers in 84 men with confirmed FM (SIR 12.6, 95% CI 3.4-32.4). CONCLUSION: Neither confirmed FM nor those without confirmed FM predicted cancer. An increased risk of breast cancer was found among those who did not meet the ACR criteria for FM. These patients should be investigated if they develop any new or warning symptoms of malignancy, and treating physicians should be vigilant with screening procedures such as mammography.

Abstract: The distribution and amount of collagen in skin from a non-tender-point area from fibromyalgia patients was assessed by quantitative analysis of amino acids and by electron and light microscopy. Skin biopsies were obtained from the front of the thigh of 27 females who fulfilled the American College of Rheumatology criteria of fibromyalgia and from eight control subjects who were matched for gender, age and physical activity. Amino acids were determined by high-performance liquid chromatography. Electron and light microscopic investigations were carried out to examine tissue structure. Among the collagen-related amino acids, the mean number of hydroxyproline residues per 1,000 residues was 52.5 and 63.4 in fibromyalgia patients and control subjects, respectively (p = 0.050); proline residues were 81.7 and 110.0 (p = 0.006); and hydroxylysine residues were 14.7 and 10.1 (p = 0.002). The total amount of skin protein in proportion to dry tissue weight was 83.4% and 72.6% in fibromyalgia and controls, respectively (p = 0.037). The overall microscopic picture was normal. The lamellar structure of the perineurium and a deficiency in collagen packing in the endoneurium was observed more frequently and to a larger extent in fibromyalgia patients than in controls. In conclusion, there are some differences between the amino acid composition of skin proteins in fibromyalgia patients compared with controls. The amount of collagen may be lower in skin from fibromyalgia patients, and collagen packing in the endoneurium may be less dense.

Abstract: OBJECTIVE: To use a new immunologic assay to investigate antipolymer antibody (APA) levels in women with fibromyalgia (FM). METHODS: The study population consisted of 35 patients with FM and 129 controls. The controls were selected based on a prior history of breast surgery and the presence or absence of a prior hospital diagnosis of soft tissue rheumatism. Study subjects underwent blood sampling, including tests for antinuclear antibodies (ANA) and APA, a clinical examination, and an interview focusing on rheumatic complaints and self-reported disability. The severity of rheumatic symptoms/signs was scored from 1 (= none) to 5 (= severe) based on the clinical examination and the interview. RESULTS: FM patients in this study represented a broad spectrum of disease severity, with the majority having mild symptoms. FM patients had a higher symptom severity and myalgic scores than controls (p < 0.001 for both variables). Adjusting for symptom severity, a weak positive association between APA levels and FM was observed (p = 0.08). The APA level was inversely associated with age, i.e., decreasing APA levels were seen with increasing age (p = 0.008). CONCLUSION: FM patients tended to have slightly higher APA levels than controls when adjusted for symptom severity. APA levels declined with age, a finding that has not been reported previously. The APA test and its clinical relevance should be evaluated in future studies.

Abstract: OBJECTIVE: To compare bone mass (BMD) in women with fibromyalgia (FM) with healthy females, and to evaluate whether self-reported pain and lack of functional capacity correlate to reduced BMD in FM patients. METHODS: Thirty-one FM patients (20 pre- and 11 postmenopausal) and fourty-one healthy women (30 pre- and 10 postmenopausal) were enrolled in the study. BMD of the lumbar spine and the femoral neck was measured by a DEXA (Norland) scanner. Self reported pain was measured on a Visual Analog Scale (VAS). The Activity of Daily Living (ADL) component of the Fibromyalgia Impact Questionnaire (FIQ-ADL) was used as measure for physical capacity. RESULTS: BMD-lumbar spine and BMD-femoral neck did not differ significantly between FM patients and controls, though premenopausal FM patients tended to have lower BMD-femoral neck (p = 0.09). Self reported pain and FIQ-ADL among FM patients correlated with BMD-femoral neck (r(s) = -0.52, p = 0.003); (r(s) = -0.31, p = 0.09). CONCLUSION: Premenopausal FM patients tended to have lower BMD of hip than controls. Self reported pain correlated negatively to BMD. Thus, the severity of FM might have a negative impact on bone mass.

Abstract: AIM: To assess the levels of hyaluronic acid (HA) in Danish patients with fibromyalgia (FM). METHODS: Serum levels of HA were determined in 53 patients with established FM and 55 control samples with a radiometric assay (Pharmacia). Values were correlated to clinical parameters of disease severity (duration of disease, tender point scales, visual analogue scales). RESULTS: There were no differences in the HA levels of patients and controls. In all the patients, except one, values were within the reference intervals. Nor was there an association between HA levels and clinical findings. CONCLUSIONS: Patients with FM do not generally have increased serum levels of HA, and other serum measurements have not been helpful in the diagnosis of FM. Some biochemical changes have been described in FM, however, and these have mainly been observed in the spinal fluid.

Abstract: OBJECTIVE: The etiologies of fibromyalgia (FM) are unknown. In some cases an acute onset following a flu-like episode is described; in other cases patients report slowly developing disease. We previously found increased prevalence of enterovirus IgM antibodies in patients with acute onset of FM compared to healthy controls. We looked for differences in antimicrobial IgM antibodies in acute versus nonacute onset FM. METHODS: Two well defined, comparable groups of patients with FM (acute 19, nonacute 20) were studied for antibodies in serum to an array of viruses including IgM antibodies. RESULTS: In most viruses no IgM antibodies were found. However, about 50% of the patients with acute FM onset had IgM antibodies against enterovirus compared to only 15% of the slow onset patients. CONCLUSION: The higher prevalence of IgM antibodies against enterovirus in patients with acute onset of FM may indicate a difference in the etiology or the immune response in these patients.
