EULAR revised recommendations for the management of fibromyalgia.

OBJECTIVE: The original European League Against Rheumatism recommendations for managing fibromyalgia assessed evidence up to 2005. The paucity of studies meant that most recommendations were 'expert opinion'. METHODS: A multidisciplinary group from 12 countries assessed evidence with a focus on systematic reviews and meta-analyses concerned with pharmacological/non-pharmacological management for fibromyalgia. A review, in May 2015, identified eligible publications and key outcomes assessed were pain, fatigue, sleep and daily functioning. The Grading of Recommendations Assessment, Development and Evaluation system was used for making recommendations. RESULTS: 2979 titles were identified: from these 275 full papers were selected for review and 107 reviews (and/or meta-analyses) evaluated as eligible. Based on meta-analyses, the only 'strong for' therapy-based recommendation in the guidelines was exercise. Based on expert opinion, a graduated approach, the following four main stages are suggested underpinned by shared decision-making with patients. Initial management should involve patient education and focus on non-pharmacological therapies. In case of non-response, further therapies (all of which were evaluated as 'weak for' based on meta-analyses) should be tailored to the specific needs of the individual and may involve psychological therapies (for mood disorders and unhelpful coping strategies), pharmacotherapy (for severe pain or sleep disturbance) and/or a multimodal rehabilitation programme (for severe disability). CONCLUSIONS: These recommendations are underpinned by high-quality reviews and meta-analyses. The size of effect for most treatments is relatively modest. We propose research priorities clarifying who will benefit from specific interventions, their effect in combination and organisation of healthcare systems to optimise outcome.

Polymyalgia rheumatica: inflammation suppression with low dose of methylprednisolone or modified-release prednisone.

OBJECTIVE: Polymyalgia rheumatica (PMR) is an inflammatory disease that affects people aged > 50 years, and is characterised by pain and morning stiffness in the shoulder and pelvic girdle with synovitis of the proximal joints and extra-articular synovial structures. It is currently mainly treated with glucocorticoids (GCs). The aim of the study was to evaluate changes in inflammatory markers and their correlations with cortisol levels after treatment with 6-methylprednisolone (6-MP) or modified-release prednisone (MR-P) in patients with "early" PMR. PATIENTS AND METHODS: The study involved 81 GC-naïve with "early" PMR diagnosed on the basis of the 2012 EULAR/ACR criteria: 38 treated with 6-MP at a starting dose of 12 mg at 8.00 a.m, gradually tapered to 8, 4 and 2 mg/day, and 43 treated with MR-P at a starting dose of 10 mg at 10 p.m, tapered to 7, 5, 3, 2 and 1 mg. The markers of inflammation (ESR mm/h, CRP mg/dL and fibrinogen mg/dL), the circulating serum levels of cytokines (TNFa and IL-6), and morning serum cortisol levels were evaluated at baseline and during GC treatment. RESULTS: There were significant differences between baseline and the end of treatment in the serum levels of IL-6 (5.3 ± 9.3 vs 2.8 ± 3.3 pg/mL; p < 0.05) and CRP (2.1 ± 3.3 vs 0.9 ± 1.7 mg/dL; p < 0.01) in the patients treated with MR-P, and in serum cortisol levels (15.8±6.4 vs 13.6+5.6 µg/dL; p < 0.01) in the patients treated with 6-MP. After the first month of treatment, 76.7% of the patients treated with MR-P had IL6 levels at or below the upper normal limit, whereas 52.6% of those treated with 6-MP had normal IL6 levels (p < 0.05). There was also a significant difference in the percentage of patients in whom the daily GC dose was tapered within eight months (6.7% in the MR-P group vs 25% in the 6-MP group; p < 0.001) and, by the end of the study, respectively 59.5% vs 35.1% patients were receiving a low GC dose or had discontinued treatment altogether (OR 2.7, 95% CI 1.0-6.77; p < 0.001). After six and 12 months, respectively 10.3% and 14.3% of the patients had discontinued MR-P, as against none of the patients treated with 6-MP (p < 0.05). CONCLUSIONS: In this prospective observational study of PMR patients receiving low-dose GCs, the changes in inflammatory markers were similar in those treated with 6-MP or MR-P, whereas morning cortisol levels remained unchanged only in the MR-P group. During the first month of treatment, MR-P chronotherapy given at bedtime significantly decreased IL-6 levels. The percentage of patients stopping GC treatment was higher in the MR-P group than in the 6-MP group.

Neurophysiological background for physical therapies in fibromyalgia.

This paper describes the techniques for controlling pain by the physical means that are most widely used clinically, particularly in the case of fibromyalgia. They are grouped on the basis of the physical energy used: mechanical, thermal (including magnetic and electromagnetic), and light (LASER). The main underlying neurophysiological mechanisms are gate activation, the stimulation of descending systems of pain control, and the endogenous opiate system.

Non pharmacological treatments in fibromyalgia.

Fibromyalgia is a complex syndrome associated with significant impairment in quality of life and function and with substantial financial costs. Once the diagnosis is made, providers should aim to increase patients' function and minimize pain. Fibromyalgia patients frequently use alternative therapies, strongly indicating both their dissatisfaction with and the substantial ineffectiveness of traditional medical therapy, especially pharmacological treatments. At present, pharmacological treatments for fibromyalgia have a rather discouraging cost/benefit ratio in terms of poor symptom control and high incidence of side effects. The interdisciplinary treatment programs have been shown to improve subjective pain with greater success than monotherapy. Physical therapies, rehabilitation and alternative therapies are generally perceived to be more "natural," to have fewer adverse effects, and in some way, to be more effective. In this review, physical exercise and multimodal cognitive behavioural therapy are presented as the more accepted and beneficial forms of nonpharmacological therapy.

EULAR evidence-based recommendations for the management of fibromyalgia syndrome.

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.

[Complementary medicine in rheumatoid arthritis]. / La medicina complementare nell'artrite reumatoide.

Use of complementary and alternative medicine (CAM) for chronic conditions has increased in recent years. CAM is immensely popular for musculoskeletal conditions and patients suffering from rheumatoid arthritis (RA) frequently try CAM. This review summarises the trial data for or against CAM as a symptomatic treatment for rheumatoid arthritis. Collectively the evidence demonstrates that some CAM modalities show significant promise, e.g. acupuncture, diets, herbal medicine, homoeopathy, massage, supplements. However, for the great majority of these therapies no evidencebased (clinical randomised trials) results are available. CAM is usually used in addition to, and not as a substitute for conventional therapies. The motivation of patients to try CAM is complex; the willingness to take control of their healthcare, the desire to try everything available, the mass-media pressure and the erroneous notion that CAM is without risks. In fact, none of these treatments is totally devoid of risks. While the use of complementary and alternative modalities for the treatment of RA continues to increase, rigorous clinical trials examining their efficacy are needed before definitive recommendations regarding the application of these modalities can be made.

Diet therapy for rheumatoid arthritis. A controlled double-blind study of two different dietary regimens.

OBJECTIVE: To evaluate the effects of a diet therapy in patients with rheumatoid arthritis (RA). METHODS: Fifty RA patients entered a 24-week double-blind, randomised, controlled-study of two different dietary regimens (an experimental diet high in unsaturated fats, low in saturated fats with hypoallergenic foods vs. a control well-balanced diet). The primary end points of the study were 20% and 50% improvement in disease activity according to composite symptoms (Paulus index) of arthritis. Other end points were the other measures of disease activity at 12 and 24 weeks of diet treatment. RESULTS: The 2 groups were comparable at inclusion. Diet treatment was well tolerated and the rate of drop-outs was low. Percentage of patients with global 20 or 50% response didn't differ between experimental and control group after the 24-week of diet treatment. The experimental diet group did better for all the variables considered but only four variables (Ritchie's index, tender and swollen joints, and ESR) reached a statistical difference by multivariate analysis. Adjusting these data for weight variations, the number of tender joints (p=0.014) and ESR (p=0.025) were still statistically significant. CONCLUSIONS: Dietary manipulation, either by modifying food supplements or by reducing weight, may give some clinical benefit although no significant improvement can be observed assessing the results with a composite index.
