Abstract
PURPOSE OF REVIEW Pain is the most common and often most troublesome feature of chronic autoimmune diseases such as psoriatic arthritis (PsA) and axial spondyloarthritis (AxSpA). A predominant concept is that the main source of pain is from disease-induced tissue inflammation and structural damage, activating peripheral nerve fibers which relay to the central nervous system. This mechanism is nociceptive pain and the presumption has been that controlling inflammation will be sufficient to reduce this form of pain. However, despite control of inflammation, patients may still have significant residual pain. RECENT FINDINGS We are learning that there are additional pain mechanisms, neuropathic and nociplastic, that are often operative in patients with rheumatologic conditions, that can significantly influence pain experience, quantitation of disease activity, and may benefit from therapeutic approaches distinct from immunotherapy. Neuropathic pain arises from diseased or damaged nerve tissue and nociplastic pain reflects sensitization of the central nervous system due to multiple genetic, neurobiologic, neural network dysregulation, and psychosocial factors. Pain arising from these mechanisms influence assessment of disease activity and thus needs to be factored into decision-making about immunotherapy efficacy. SUMMARY This review addresses the importance of accurately assessing the complex mechanisms of pain experience in patients with PsA and AxSpA to more appropriately manage immunomodulatory, neuromodulatory, and nonpharmacologic therapies.

Efficacy of aquatic vs land-based therapy for pain management in women with fibromyalgia: a randomised controlled trial. Physiotherapy 2024; 123:91-101. [PMID: 38447497 DOI: 10.1016/j.physio.2024.02.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2022] [Revised: 12/28/2023] [Accepted: 02/14/2024] [Indexed: 03/08/2024]
Abstract
OBJECTIVE To determine the efficacy of two physiotherapeutic interventions - aquatic therapy (AT) and land-based therapy (LBT) - for reducing pain in women with fibromyalgia. DESIGN Single-blind, randomised controlled, equivalence trial. SETTING Fibromyalgia, Chronic Fatigue Syndrome and Multiple Chemical Sensitivity Association in A Coruña, Spain. PARTICIPANTS Forty women with fibromyalgia were assigned at random in a 1:1 manner to two groups: AT (n = 20) and LBT (n = 20). INTERVENTIONS Two therapeutic exercise programmes, with 60-min sessions, were undertaken three times per week for 12 weeks. Sessions were carried out in groups by a trained physiotherapist. OUTCOME The primary outcome was pain intensity (visual analogue scale). The secondary outcomes were pressure pain threshold (algometer), quality of life (Revised Fibromyalgia Impact Questionnaire), sleep quality (Pittsburgh Sleep Quality Index), fatigue (Multidimensional Fatigue Inventory) and physical ability (6-Minute Walk Test). Patients were evaluated at baseline, 12 weeks (post-treatment) and 18 weeks (follow-up). The statistical analysis was per-protocol. P < 0.05 was considered to indicate significance. Effect size was calculated. RESULTS The mean age was 50 [standard deviation (SD) 9] years, with median body mass index of 27 [interquartile range (IQR) 25-30] kg/m2 and median symptom duration of 11 (IQR 6-15) years. No differences were observed between the groups post-treatment, but differences in favour of AT were found in pain intensity [2.7 (IQR 1.5-4.9) vs 5.5 (IQR 3.3-7.6); p= 0.023; large effect, Cohen's d= 0.8; 95% confidence interval (CI) 0.1-1.5] and sleep quality [12.0 (IQR 7.3-15.3) vs 15.0 (IQR 13.0-17.0); p= 0.030; large effect, Cohen's d= 0.8; 95% CI 0.1-1.5] at follow-up. CONCLUSIONS The results suggest that AT is better than LBT for reducing pain intensity and improving sleep quality after 6 weeks of follow-up. AT may be a good treatment option for women with fibromyalgia. CLINICAL TRIALS REGISTRATION NUMBER ClinicalTrials.gov NCT02695875 CONTRIBUTION OF THE PAPER.

Abstract
Aim To develop an eHealth resource to support fibromyalgia patients and explore it for usability and impact on their self-management and self-efficacy. Background Fibromyalgia is a complex, non-progressive chronic condition characterised by a bewildering array of symptoms for patients to self-manage. International guidelines recommend patients receive illness-specific information once diagnosed to promote self-management and improve health-related quality of life. Design A 3-phase mixed methods exploratory sequential design. Methods Qualitative interviews explored the information and self-management needs of fibromyalgia patients attending a large tertiary hospital in Dublin. Identified themes together with an extensive review of the literature of interventions proven to be impactful by patients with fibromyalgia were utilised in the design and development of the eHealth resource. The resource was tested for usability and impact using pre and post-intervention outcomes measures. Results Patient interviews highlighted a lack of easy accessible evidenced information to support self-management implicating the urgent need for a practical solution through development of a tailored eHealth resource. Six themes emerged for inclusion; illness knowledge, primary symptoms, treatment options, self-management strategies, practical support and reliable resources. Forty-five patients who tested the site for usability and impact demonstrated a statistically significant improvement in self-efficacy after 4 weeks access with a medium positive effect size. Patients with the most severe fibromyalgia impact scores pre-intervention demonstrated the most improvement after 4 weeks. Patients gave the resource a System Usability Score A rating, highly recommending it for fellow patients diagnosed with fibromyalgia. Conclusions The study demonstrated how the development of a novel eHealth resource positively impacted fibromyalgia patients' self-efficacy to cope with this debilitating condition. Impact This study suggests that access to eHealth can positively impact patients self-efficacy, has the potential to be a template for eHealth development in other chronic conditions, supporting advanced nurse practitioners working in chronic disease management.

A Personalized Mediterranean Diet Improves Pain and Quality of Life in Patients with Fibromyalgia. Pain Ther 2024; 13:609-620. [PMID: 38683449 PMCID: PMC11111631 DOI: 10.1007/s40122-024-00598-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2024] [Accepted: 03/27/2024] [Indexed: 05/01/2024] Open
Abstract
INTRODUCTION Fibromyalgia is a form of chronic pain that affects a large number of women. It can start at any age and last a lifetime, with no cure. The Mediterranean diet is said to have an anti-inflammatory effect. Therefore, this study was conducted to investigate possible beneficial effects of a personalized Mediterranean diet in patients with fibromyalgia. METHODS Outpatients with fibromyalgia were recruited and invited to participate in the study, including clinical, nutritional, and dietary assessments. Patients received a personalized Mediterranean diet (DIET group) or a general balanced diet (NODIET group) to be followed for 8 weeks. All tests were carried out at baseline and repeated after 4 and 8 weeks. RESULTS In total, 100 subjects were included, 84 of whom completed the study. Most of the patients showed incorrect habits in terms of food choices, timing of meals and composition of nutrients. The DIET group showed an improvement in most of the fibromyalgia parameters, including the disability scores, fatigue, and anxiety. CONCLUSIONS The habit of eating inflammatory foods and/or eating meals with the wrong nutritional content would increase the negative status of patients with fibromyalgia. With this study, we confirm that proper attention to feeding habits would improve the quality of life of such patients.

Recommendations for patient education in the management of persistent pelvic pain: a systematic review of clinical practice guidelines. Pain 2024; 165:1207-1216. [PMID: 38112691 DOI: 10.1097/j.pain.0000000000003137] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2023] [Accepted: 10/01/2023] [Indexed: 12/21/2023]
Abstract
ABSTRACT Patient education has a critical role in the management of pain. There is considerable heterogeneity in patient education for females with persistent pelvic pain (PPP), and it remains unclear what is considered best clinical practice. Therefore, this systematic review identified and summarised recommendations for patient education in the management of benign gynaecological and urological conditions associated with PPP, as endorsed by international guidelines. Academic and relevant guideline databases were searched from inception to May 2022. Included guidelines were those for the management of benign gynaecological and urological conditions associated with PPP in adult females published in English, of any publication date, and endorsed by a professional organisation or society. Two independent reviewers screened 3097 records; 17 guidelines were included in the review. Guideline quality was assessed using the Appraisal of Guidelines for Research and Evaluation II (AGREE-II) tool. Recommendations were pooled using descriptive synthesis. Persistent pelvic pain guideline quality was generally poor. Three guidelines were classified as "excellent" (The NICE, RANZCOG, and ESHRE endometriosis guidelines) and therefore recommended for use. Eleven guidelines (64.7%) recommended patient education for females with PPP. Recommendations for education content were variable, however most frequently covered treatment strategies and pelvic pain diagnoses. For education delivery, the most frequent recommendations were for support groups and written/printed materials. Further research into tailored education interventions is needed for females with PPP.

Effect of exposure-based vs traditional cognitive behavior therapy for fibromyalgia: a two-site single-blind randomized controlled trial. Pain 2024; 165:1278-1288. [PMID: 38131181 PMCID: PMC11090030 DOI: 10.1097/j.pain.0000000000003128] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2023] [Revised: 09/13/2023] [Accepted: 10/13/2023] [Indexed: 12/23/2023]
Abstract
ABSTRACT Fibromyalgia is a debilitating pain condition for which treatment effects are typically modest. The most evaluated psychological treatment is traditional cognitive behavior therapy (T-CBT), but promising effects have recently been seen in exposure-based cognitive behavior therapy (Exp-CBT). We investigated whether Exp-CBT was superior to T-CBT in a randomized controlled trial. Self-referred participants with fibromyalgia (N = 274) were randomized (1:1) to 10 weeks of Exp-CBT or T-CBT. Treatments were delivered online and presented as "CBT for fibromyalgia." Participants were assessed at baseline, weekly during treatment, posttreatment, and at 6- and 12-month follow-up. Primary outcome was the difference in reduction in fibromyalgia severity as measured using the Fibromyalgia Impact Questionnaire (FIQ) over 11 assessment points from baseline to posttreatment, modelled within an intention-to-treat framework using linear mixed effects models fitted on multiple imputed data. Approximately 91% of weekly FIQ scores were collected over the main phase. There was no significant difference between Exp-CBT and T-CBT in the mean reduction of fibromyalgia severity from pretreatment to posttreatment (b = 1.3, 95% CI -3.0 to 5.7, P = 0.544, d = -0.10). Minimal clinically important improvement was seen 60% in Exp-CBT vs 59% in T-CBT. Effects were sustained up to 12 months posttreatment. This well-powered randomized trial indicated that Exp-CBT was not superior to T-CBT for fibromyalgia. Both treatments were associated with a marked reduction in fibromyalgia severity, and the online treatment format might be of high clinical utility. T-CBT can still be regarded a reference standard treatment that remains clinically relevant when compared to novel treatment approaches.

Influence of Transcutaneous Electrical Nerve Stimulation (TENS) on Pressure Pain Thresholds and Conditioned Pain Modulation in a Randomized Controlled Trial in Women With Fibromyalgia. THE JOURNAL OF PAIN 2024; 25:104452. [PMID: 38154621 PMCID: PMC11128356 DOI: 10.1016/j.jpain.2023.12.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/27/2023] [Revised: 12/18/2023] [Accepted: 12/19/2023] [Indexed: 12/30/2023]
Abstract
Transcutaneous electrical nerve stimulation (TENS) effectively reduces pain in fibromyalgia (FM). The purpose of this study was to examine the influence of TENS use on pressure pain thresholds (PPT) and conditioned pain modulation (CPM) in individuals with FM using data from the Fibromyalgia Activity Study with TENS trial (NCT01888640). Individuals with FM were randomly assigned to receive active TENS, placebo TENS, or no TENS for 4 weeks. A total of 238 females satisfied the per-protocol analysis among the active TENS (n = 76), placebo TENS (n = 68), and no TENS (n = 94) groups. Following 4 weeks of group allocation, the active TENS group continued for an additional 4 weeks of active TENS totaling 8 weeks (n = 66), the placebo and no TENS groups transitioned to receive 4 weeks of active TENS (delayed TENS, n = 161). Assessment of resting pain, movement-evoked pain (MEP), PPT, and CPM occurred prior to and following active, placebo, or no TENS. There were no significant changes in PPT or CPM among the active TENS, placebo TENS, or no TENS groups after 4 weeks. Individuals who reported clinically relevant improvements in MEP (≥30% decrease) demonstrated increases in PPT (P < .001), but not CPM, when compared to MEP non-responders. There were no significant correlations among the change in PPT or CPM compared to MEP and resting pain following active TENS use (active TENS + delayed TENS). PPT and CPM may provide insight to underlying mechanisms contributing to pain; however, these measures may not relate to self-reported pain symptoms. PERSPECTIVE: Pressure pain threshold increased in individuals with clinically relevant improvement (≥30%) in MEP, indicating the clinical relevance of PPT for understanding mechanisms contributing to pain. CPM was not a reliable indicator of treatment response in MEP responders.

Abstract
BACKGROUND AND PURPOSE Fibromyalgia is a complex clinical disorder with an unknown aetiology, characterized by generalized pain and co-morbid symptoms such as anxiety and depression. An imbalance of oxidants and antioxidants is proposed to play a pivotal role in the pathogenesis of fibromyalgia symptoms. However, the precise mechanisms by which oxidative stress contributes to fibromyalgia-induced pain remain unclear. The transient receptor potential ankyrin 1 (TRPA1) channel, known as both a pain sensor and an oxidative stress sensor, has been implicated in various painful conditions. EXPERIMENTAL APPROACH The feed-forward mechanism that implicates reactive oxygen species (ROS) driven by TRPA1 was investigated in a reserpine-induced fibromyalgia model in C57BL/6J mice employing pharmacological interventions and genetic approaches. KEY RESULTS Reserpine-treated mice developed pain-like behaviours (mechanical/cold hypersensitivity) and early anxiety-depressive-like disorders, accompanied by increased levels of oxidative stress markers in the sciatic nerve tissues. These effects were not observed upon pharmacological blockade or global genetic deletion of the TRPA1 channel and macrophage depletion. Furthermore, we demonstrated that selective silencing of TRPA1 in Schwann cells reduced reserpine-induced neuroinflammation (NADPH oxidase 1-dependent ROS generation and macrophage increase in the sciatic nerve) and attenuated fibromyalgia-like behaviours. CONCLUSION AND IMPLICATIONS Activated Schwann cells expressing TRPA1 promote an intracellular pathway culminating in the release of ROS and recruitment of macrophages in the mouse sciatic nerve. These cellular and molecular events sustain mechanical and cold hypersensitivity in the reserpine-evoked fibromyalgia model. Targeting TRPA1 channels on Schwann cells could offer a novel therapeutic approach for managing fibromyalgia-related behaviours.

Abstract
Fibromyalgia syndrome (FMS) is a chronic pain syndrome characterized by disruptions in pain processing within the central nervous system. It exhibits a high prevalence among patients with a history of traumatic experiences, notably childhood sexual abuse (CSA). This study compared the efficacy of hyperbaric oxygen therapy (HBOT) to the current pharmacological standard of care for individuals suffering from CSA-related FMS. Forty-eight participants diagnosed with FMS and a history of CSA were randomly assigned to either the HBOT group (60 sessions of 100% oxygen at 2 ATA for 90 min, with air breaks every 5 min) or the medication (MED) group (FDA-approved medications, Pregabalin and Duloxetine). The primary endpoint was the Fibromyalgia impact questionnaire (FIQ) score, while secondary endpoints encompassed emotional status and daily functioning questionnaires, as well as pain thresholds and conditioned pain modulation tests. Brain activity was evaluated through single photon emission computed tomography (SPECT). Results revealed a significant group-by-time interaction for the FIQ score favoring HBOT over MED (p < 0.001), with a large effect size (Cohen's d = - 1.27). Similar findings were observed in emotional symptoms and functional measures. SPECT imaging demonstrated an increase in activity in pre-frontal and temporal brain areas, which correlated with symptoms improvement. In conclusion, HBOT exhibited superior benefits over medications in terms of physical, functional, and emotional improvements among FMS patients with a history of CSA. This associated with increased activity in pre-frontal and temporal brain areas, highlighting the neuroplasticity effect of HBOT.

Abstract
Nociplastic pain is a mechanistic term used to describe pain that arises or is sustained by altered nociception, despite the absence of tissue damage. Although nociplastic pain has distinct pathophysiology from nociceptive and neuropathic pain, these pain mechanisms often coincide within individuals, which contributes to the intractability of chronic pain. Key symptoms of nociplastic pain include pain in multiple body regions, fatigue, sleep disturbances, cognitive dysfunction, depression and anxiety. Individuals with nociplastic pain are often diffusely tender - indicative of hyperalgesia and/or allodynia - and are often more sensitive than others to non-painful sensory stimuli such as lights, odours and noises. This Review summarizes the risk factors, clinical presentation and treatment of nociplastic pain, and describes how alterations in brain function and structure, immune processing and peripheral factors might contribute to the nociplastic pain phenotype. This article concludes with a discussion of two proposed subtypes of nociplastic pain that reflect distinct neurobiological features and treatment responsivity.

Abstract
OBJECTIVE An important component to effective fibromyalgia treatment is patient education about the condition. While previous educational interventions have been developed, these have not incorporated the lived experiences of patients and may not address common misunderstandings among those who may benefit from these interventions. This study aimed to explore understanding, confusion, and gaps in knowledge about fibromyalgia among those who report a fibromyalgia diagnosis. METHODS Participants were recruited via clinic flyers and the social media page of a chronic pain research laboratory. Participants completed an online survey that assessed their knowledge of fibromyalgia via open-ended questions. Responses were analyzed via thematic analysis to identify, analyze, and report themes. RESULTS Thirty-eight participants completed the survey (63% female, ages 18-68). Common themes that arose from patients included being unsure of the cause of their fibromyalgia, frustration and confusion about the random/variable nature of symptoms and flares, feeling that their condition was invisible, and desiring more information on available treatments. CONCLUSION Participants in this study expressed confusion about many aspects of fibromyalgia and a desire for more understanding from others in their life about this condition. PRACTICE IMPLICATIONS Future interventions would benefit from tailoring fibromyalgia education to the specific knowledge and lived experiences of patients.

Abstract
Many patients with rheumatologic conditions receive care from physicians other than rheumatologists. Here we note key findings from 6 studies in rheumatology published in 2023 that offer valuable insights for internal medicine specialists and subspecialists outside of rheumatology. The first study investigated the effect of low-dose glucocorticoids on patients with rheumatoid arthritis (RA) over 2 years and challenged existing perceptions about the risks of glucocorticoids in this setting. The second study focused on the updated guideline for preventing and treating glucocorticoid-induced osteoporosis. With the chronic and widespread use of glucocorticoids, the American College of Rheumatology emphasized the importance of assessing fracture risk and initiating pharmacologic therapy when appropriate. The third study explored the potential use of methotrexate in treating inflammatory hand osteoarthritis, suggesting a novel approach to managing this challenging and common condition. The results of the fourth article we highlight suggest that sarilumab has promise as an adjunct treatment of polymyalgia rheumatica relapse during glucocorticoid dosage tapering. The fifth study evaluated sublingual cyclobenzaprine for fibromyalgia treatment, noting both potential benefits and risks. Finally, the sixth article is a systematic review and meta-analysis that assessed the therapeutic equivalence of biosimilars and reference biologics in the treatment of patients with RA. Knowledge of this recent literature will be useful to clinicians regardless of specialty who care for patients with these commonly encountered conditions.

Abstract
PURPOSE Sedentary behaviour is associated with pain, fatigue, and a more severe impact of the disease in fibromyalgia, independently of physical activity levels. Despite this knowledge, little attention has been attributed to estimate sedentary behaviour in this population. The aims of this meta-analysis were to: (a) establish the pooled mean time spent sedentary, (b) investigate moderators of sedentary levels, and (c) explore differences with age- and gender-matched general population controls in people with fibromyalgia (PwF). METHODS Two independent authors searched major databases until 1 December 2022. A random effects meta-analysis was performed. The methodological quality of included studies was assessed with the Quality Assessment Tool for Observational Cohort and Cross-sectional Studies. RESULTS Across 7 cross-sectional studies of fair methodological quality, there were 1500 patients with fibromyalgia (age range = 43-53 years). PwF spent 545.6 min/day (95% CI = 523.7-567.5, p < 0.001, N = 3) engaging in sedentary behaviour. Self-reported questionnaires overestimate sedentary levels with 314.3 min/day (95% CI = 302.0-326.6, p = 0.001, N = 2). PwF spent 36.14 min/day (95% CI = 16.3-55.9, p < 0.001) more in sedentary behaviour than general population controls. CONCLUSIONS PwF are more sedentary than the general population. The limited available data should however be considered with caution due to substantial heterogeneity.

Abstract
Background In patients with fibromyalgia, exercise and education are recommended to decrease pain level and improve pain management. The latest scientific evidence recommends to focus interventions on the upper limb. The aim of this pilot study was to compare the immediate effect of physical activity education vs. a control group on pain and muscle capacity in fibromyalgia patients. Method Fifty-six participants with fibromyalgia were randomized into an experimental group and a control group. The intervention consisted in watching a five-minute video that provided information about fibromyalgia, pain, kinesiophobia and physical activity. The control group watched a neutral five-minute video about beavers in Quebec. Following the video, participants performed a muscular fatigue task consisting of a repeated unilateral shoulder abduction task. At baseline and following the muscular fatigue task, maximal voluntary contraction (MVC) in shoulder abduction was assessed as well as pain level and pressure pain threshold (PPT) in the upper limb. Electromyographic activity was also assessed for upper trapezius and middle deltoid muscles. Two-way repeated measures analysis of variance was used to compare the MVC, PPT, and pain level before and after the muscular fatigue task between groups. Results The experimental group showed a significantly lower increase in pain than the control group in the middle deltoid muscle (p = 0.002) when assessed by verbal pain rating scale. No significant interaction or main effect of Group and Time were observed for the pain level at the upper trapezius and elbow extensor muscles nor for any of the PPT measures. According to electromyographic data, the median frequency values indicate that neither group experienced muscle fatigue during the repeated contraction task. Conclusions The preliminary results suggest that a short physical activity education video positively influenced middle deltoid pain following repeated abduction in participants with fibromyalgia. Electromyographic analysis showed no evidence of objective muscle fatigue, suggesting that there might be a partial disconnection between the perception of muscle fatigue and the physiological biomarkers associated with muscle fatigue.

[PMID: 38662182 DOI: 10.1007/s10787-024-01473-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2023] [Accepted: 03/27/2024] [Indexed: 04/26/2024]
Abstract
Fibromyalgia is a potentially disabling idiopathic disease characterized by widespread chronic pain associated with comorbidities such as fatigue, anxiety, and depression. Current therapeutic approaches present adverse effects that limit adherence to therapy. Diosmetin, an aglycone of the flavonoid glycoside diosmin found in citrus fruits and the leaves of Olea europaea L., has antinociceptive, anti-inflammatory, and antioxidant properties. Here, we investigated the effect of diosmetin on nociceptive behaviors and comorbidities in an experimental fibromyalgia model induced by reserpine in mice. To induce the experimental fibromyalgia model, a protocol of subcutaneous injections of reserpine (1 mg/kg) was used once a day for three consecutive days in adult male Swiss mice. Mice received oral diosmetin on the fourth day after the first reserpine injection. Nociceptive (mechanical allodynia, muscle strength, and thermal hyperalgesia) and comorbid (depressive-like and anxiety behavior) parameters were evaluated. Potential adverse effects associated with diosmetin plus reserpine (locomotor alteration, cataleptic behavior, and body weight and temperature changes) were also evaluated. Oral diosmetin (0.015-1.5 mg/kg) reduced the mechanical allodynia, thermal hyperalgesia, and loss of muscle strength induced by reserpine. Diosmetin (0.15 mg/kg) also attenuated depressive-like and anxiety behaviors without causing locomotor alteration, cataleptic behavior, and alteration in weight and body temperature of mice. Overall, diosmetin can be an effective and safe therapeutic alternative to treat fibromyalgia symptoms, such as pain, depression and anxiety.

Shared and distinct effect mediators in exposure-based and traditional cognitive behavior therapy for fibromyalgia: Secondary analysis of a randomized controlled trial. Behav Res Ther 2024; 178:104546. [PMID: 38685153 DOI: 10.1016/j.brat.2024.104546] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2024] [Revised: 04/19/2024] [Accepted: 04/19/2024] [Indexed: 05/02/2024]
Abstract
Fibromyalgia is a chronic pain condition associated with substantial suffering and societal costs. Traditional cognitive behavior therapy (T-CBT) is the most evaluated psychological treatment, but exposure therapy (Exp-CBT) has shown promise with a pronounced focus on the reduction of pain-related avoidance behaviors. In a recent randomized controlled trial (N = 274), we found that Exp-CBT was not superior to T-CBT (d = -0.10) in reducing overall fibromyalgia severity. This study investigated pain-related avoidance behaviors, pain catastrophizing, hypervigilance, pacing, overdoing and physical activity as potential mediators of the treatment effect. Mediation analyses were based on parallel process growth models fitted on 11 weekly measurement points, and week-by-week time-lagged effects were tested using random intercepts cross-lagged panel models. Results indicated that a reduction in avoidance behaviors, pain catastrophizing, and hypervigilance were significant mediators of change in both treatments. An increase in pacing and a reduction in overdoing were significant mediators in T-CBT only. Physical activity was not a mediator. In the time-lagged analyses, an unequivocal effect on subsequent fibromyalgia severity was seen of avoidance and catastrophizing in Exp-CBT, and of overdoing in T-CBT. Exposure-based and traditional CBT for fibromyalgia appear to share common treatment mediators, namely pain-related avoidance behavior, catastrophizing and hypervigilance.

Severe fibromyalgia alleviated by the unique muscle relaxation method of applying low force: A case report. Medicine (Baltimore) 2024; 103:e37929. [PMID: 38640262 PMCID: PMC11030016 DOI: 10.1097/md.0000000000037929] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/09/2024] [Accepted: 03/28/2024] [Indexed: 04/21/2024] Open
Abstract
RATIONALE Fibromyalgia (FM) is characterized by idiopathic persistent chronic pain in the ligaments or musculoskeletal system, and more than half of the patients with FM might have migraine headaches. Direct musculoskeletal intervention could be a non-pharmacological management to relieve symptoms. However, patients with severe FM often have intense pain from only a soft touch, thereby rendering musculoskeletal intervention challenging. PATIENT CONCERNS A 47-year-old man had progressing intense pain, and this affected his everyday life. There were no abnormal physical findings on laboratory examination such as levels of complement, antinuclear antibodies, and C-reactive protein, which were within normal limits. Magnetic resonance imaging did not indicate abnormalities. DIAGNOSES, INTERVENTIONS, AND OUTCOMES The patient satisfied the American College of Rheumatology criteria. Finally, we made a final diagnosis of fibromyalgia. The therapeutic intervention of Kanshoho, the unique muscle relaxation technique with low force, relieved his pain. LESSONS If Kanshoho is carefully applied in a state of hospitalization under surveillance by an experienced physician, it could be a promising muscle relaxation method. Relaxing the trapezius muscle and reducing its intramuscular pressure might be key in treating patients with severe FM. However, it needs elucidation of its mechanism.

Effects of home-based exercise on the health of patients with fibromyalgia syndrome: a systematic review of randomized clinical trials. Disabil Rehabil 2024:1-12. [PMID: 38588585 DOI: 10.1080/09638288.2024.2337105] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2023] [Accepted: 03/24/2024] [Indexed: 04/10/2024]
Abstract
PURPOSE Analyze the effects of interventions with home-based physical exercise on the health of patients with fibromyalgia and the characteristics of the protocols used. METHODS This systematic review was registered at PROSPERO and followed the PRISMA recommendations. Searches were performed in six electronic databases. Eligibility criteria for the selection of studies were compiled using the acronym PICOS. Data were extracted and checked in a Microsoft Excel® spreadsheet and the risk of bias was assessed using the Rob 2 tool. RESULTS The search resulted in seven studies included for analysis. Among them, the most common modality was aerobic exercise. The analyzed outcomes were: pain, quality of life, depression, anxiety, disease severity, physical function, pain catastrophizing, self-efficacy, psychological well-being, sleep quality and somatosensory and temporal discrimination. The effects of home-based exercise are limited, and improvements in pain and quality of life was found. For the other outcomes, the results were inconclusive. Most studies presented some concerns about the risk of bias. CONCLUSION It is necessary to expand the evidence on home-based exercises for fibromyalgia, as this is the first systematic review on the subject. Subsequent research should focus on methodological rigor and protocol detail, allowing findings to be replicated.

Online Questionnaire with Fibromyalgia Patients Shows Negative Correlations between Disease Severity and Adherence to Mediterranean Diet. Nutrients 2024; 16:1078. [PMID: 38613111 PMCID: PMC11013287 DOI: 10.3390/nu16071078] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2024] [Revised: 04/03/2024] [Accepted: 04/04/2024] [Indexed: 04/14/2024] Open
Abstract
Fibromyalgia (FM) is a multidimensional disorder in which intense chronic pain is accompanied by a variety of psychophysical symptoms that impose a burden on the patients' quality of life. Despite the efforts and the recent advancement in research, FM pathogenesis and effective treatment remain unknown. Recently, the possible role of dietary patterns and/or components has been gaining attention. The current study aimed to investigate a potential correlation between adherence to the Mediterranean diet (MedDiet) and FM severity in a sample of Italian FM patients. An online survey was designed, composed of customized questions and validated questionnaires with the aim of investigating the intensity and type of pain, the presence of other psychophysical symptoms, the overall impact of FM, general food and lifestyle habits, and adherence to the MedDiet. The collected responses were analyzed for descriptive statistics, linear regression, and propensity score analyses. The results show that, despite considerable use of pharmaceuticals and supplements, FM participants suffered from a high-severity grade disease. However, those with good adherence to the MedDiet experienced a lower pain intensity and overall FM impact. A propensity score analysis indicates a positive influence of the MedDiet against FM severity, thus unveiling the need for well-designed intervention studies to evaluate the therapeutic potential of different dietary patterns.

Effects of Prolonged Medical Fasting during an Inpatient, Multimodal, Nature-Based Treatment on Pain, Physical Function, and Psychometric Parameters in Patients with Fibromyalgia: An Observational Study. Nutrients 2024; 16:1059. [PMID: 38613092 PMCID: PMC11013748 DOI: 10.3390/nu16071059] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2024] [Revised: 03/22/2024] [Accepted: 03/29/2024] [Indexed: 04/14/2024] Open
Abstract
Fibromyalgia syndrome (FMS) is a common chronic pain disorder and often occurs as a concomitant disease in rheumatological diseases. Managing FMS takes a complex approach and often involves various non-pharmacological therapies. Fasting interventions have not been in the focus of research until recently, but preliminary data have shown effects on short- and medium-term pain as well as on physical and psychosomatic outcomes in different chronic pain disorders. This single-arm observational study investigated the effects of prolonged fasting (3-12 days, <600 kcal/d) embedded in a multimodal treatment setting on inpatients with FMS. Patients who were treated at the Department of Internal Medicine and Nature-Based Therapies of the Immanuel Hospital Berlin, Germany, between 02/2018 and 12/2020 answered questionnaires at hospital admission (V0) and discharge (V1), and then again three (V2), six (V3), and 12 (V4) months later. Selected routine blood and anthropometric parameters were also assessed during the inpatient stay. A total of 176 patients with FMS were included in the study. The Fibromyalgia Impact Questionnaire (FIQ) total score dropped by 13.7 ± 13.9 (p < 0.001) by V1, suggesting an improvement in subjective disease impact. Pain (NRS: reduction by 1.1 ± 2.5 in V1, p < 0.001) and quality of life (WHO-5: +4.9 ± 12.3 in V1, p < 0.001) improved, with a sustainable effect across follow-up visits. In contrast, mindfulness (MAAS: +0.3 ± 0.7 in V1, p < 0.001), anxiety (HADS-A: reduction by 2.9 ± 3.5 in V1, p < 0.0001), and depression (HADS-D: reduction by 2.7 ± 3.0 in V1, p < 0.0001) improved during inpatient treatment, without longer-lasting effects thereafter. During the study period, no serious adverse events were reported. The results suggest that patients with FMS can profit from a prolonged therapeutic fasting intervention integrated into a complex multimodal inpatient treatment in terms of quality of life, pain, and disease-specific functional parameters. ClinicalTrials.gov Identifier: NCT03785197.

In-Person or Virtual Educational Preferences in Patients With Fibromyalgia: A Cross-Sectional Survey Study at an Academic Medical Center. Pain Manag Nurs 2024:S1524-9042(24)00104-8. [PMID: 38570215 DOI: 10.1016/j.pmn.2024.03.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2023] [Revised: 03/06/2024] [Accepted: 03/10/2024] [Indexed: 04/05/2024]
Abstract
PURPOSE Patient education is a core component of treating fibromyalgia and central sensitization disorders. We sought to evaluate whether patients with fibromyalgia prefer virtual or in-person educational classes as part of their treatment program, identify underlying factors with their educational modality choice, and highlight benefits or barriers associated with in-person or online educational sessions. DESIGN A cross-sectional survey with a qualitative feedback component was utilized. METHODS A voluntary, anonymous survey was distributed to all participants (in-person and virtual) of the fibromyalgia and chronic fatigue clinic treatment program from October 2021 through March 2022. RESULTS In total 90 participants completed the survey. Nearly all (94%) agreed that the pathophysiologic education was relevant and valuable and (98%) agreed to feeling confident with implementing management strategies. Perceived connection between the participants varied between groups (85% of in-person vs 48% of online; p < .001), as did perceived engagement (100% of in-person vs 71% of online; p = .001). CONCLUSIONS Patients value education and find it useful in treating fibromyalgia, regardless of the educational modality. The online group reported more limitations including less engagement, class participation, and connection with peers. CLINICAL IMPLICATIONS As virtual education platforms become more widely available and may be easier to access than in-person options, it is important to understand patient preferences, benefits, and disadvantages of educational modalities to ensure education and patient outcomes remain equitable.

Abstract
Fibromyalgia is a chronic, widespread pain disorder that is strongly represented across the affective and cognitive dimensions of pain, given that the underlying pathophysiology of the disorder is yet to be identified. These affective and cognitive deficits are crucial to understanding and treating the fibromyalgia pain experience as a whole but replicating this multidimensionality on a preclinical level is challenging. To understand the underlying mechanisms, animal models are used. In this scoping review, we evaluate the current primary animal models of fibromyalgia regarding their translational relevance within the affective and cognitive pain realms, as well as summarize treatments that have been identified preclinically for attenuating these deficits.

Abstract
OBJECTIVE This review aimed to compare the effectiveness of resistance exercise with that of other exercises in functional improvement and pain control in patients with fibromyalgia. DESIGN PubMed, Embase, Scopus, and Cochrane databases were searched for studies published from their inception until March 2023. The following medical search heading terms were used: "resistance OR strength OR strengthening" AND "fibromyalgia." The analysis was performed using the statistical package Review Manager, version 5.4.1. RESULTS This study reviewed 11 randomized controlled trials involving 530 patients. In comparison with no intervention, resistance exercise reduced the Fibromyalgia Impact Questionnaire total score, pain score, tender points, and depression and improved physical function. Compared with flexibility exercise, resistance exercise reduced the Fibromyalgia Impact Questionnaire total score. Compared with aerobic exercise, resistance exercise shows similar effects on pain control, reduction of tender points, and improvement of physical function. CONCLUSIONS Compared with other exercises, resistance exercise demonstrated a more favorable effect on the Fibromyalgia Impact Questionnaire total score, and the effects on pain control, tender points, physical function, and depression were comparable. Thus, resistance exercise exhibits comparable or superior effects when compared with other interventions and more precise research is needed to confirm this conclusion.

Abstract
Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a demanding medical condition for patients and society. It has raised much more public awareness after the COVID-19 pandemic since ME/CFS and long-COVID patients share many clinical symptoms such as debilitating chronic fatigue. However, unlike long COVID, the etiopathology of ME/CFS remains a mystery despite several decades' research. This review moves from pathophysiology of ME/CFS through the compelling evidence and most interesting hypotheses. It focuses on the pathophysiology of skeletal muscle by proposing the hypothesis that skeletal muscle tissue offers novel opportunities for diagnosis and treatment of this syndrome and that new evidence can help resolve the long-standing debate on terminology.

Abstract
OBJECTIVES The aim of the study was to examine the effectiveness of Clinical Pilates exercises and connective tissue massage (CTM) in individuals with Fibromyalgia (FM) on pain, disease impact, functional status, anxiety, quality of life and biopsychosocial status. METHODS 32 women were randomly divided into two groups as intervention gorup (CTM + Clinical Pilates exercises, n = 15, mean age = 48.80 ± 7.48) and control gorup (Clinical Pilates exercises, n = 17, mean age = 55.64 ± 7.87). The number of painful regions were assessed with Pain Location Inventory (PLI), disease impact with Fibromyalgia Impact Questionnare (FIQ), functional status with Health Assessment Questionnare (HAQ), anxiety with Beck Anxiety Inventory (BAI), quality of life with Short Form-36 (SF-36) and biopsychosocial status with Biopsychosocial Questionnaire (BETY-BQ) were evaluated. All evaluations were made before and after treatment. Both treatments were applied 3 times a week for 6 weeks. RESULTS When the pre-treatment and post-treatment results are analyzed; significant difference was observed in PLI (p = 0.007; effect size 1.273), FIQ (p = 0.004; effect size 0.987), SF-36 physical component (p = 0.025; effect size -0.496) and mental component (p = 0.017; effect size -0.761) in the intervention group while the significant difference was observed in FIQ (p = 0.001; effect size 1.096) and BAI (p = 0.043; effect size 0.392), SF-36 physical component (p = 0.008; effect size -0.507) and mental component (p = 0.024; effect size -0.507) in the control group. When the delta values of the groups are compared, the difference was determined only in the PLI (p = 0.023) in favor of the intervention group. CONCLUSIONS CTM can be effective in reducing the number of painful areas in addition to the positive effects of clinical Pilates exercises in women with FM.

Abstract
Fibromyalgia can be considered to be a model of chronic pain resulting from dysregulation of pain processing. From a psychological point of view, it is possible to consider transdiagnostic processes that would participate in both the dysregulation of pain and associated emotions. OBJECTIVE The aim of this study was to test the links that exist between the tendency to Repetitive Negative Thinking (RNT) and the anxious-depressive manifestations in fibromyalgia. More specifically, we wanted to test a double mediation model where RNT would mediate the link between pain and depression/anxiety via catastrophizing. METHOD Eighty-two patients with fibromyalgia completed a series of questionnaires evaluating their level of depression, anxiety, disability related to pain, catastrophizing as well as various measures of Repetitive Thoughts. RESULTS The results showed strong correlations between RNT levels, pain, and anxious-depressive manifestations in this population. Moreover, the links between pain and depression/anxiety were mediated by catastrophizing and RNT in serial. CONCLUSION Results support the interest of studying RNT as a transdiagnostic process in fibromyalgia pain. Considering RNT in fibromyalgia allows a better understanding of tthe links that exist between pain and emotional disorders in this population and thus to better understand the psychopathological comorbidity of fibromyalgia.

Abstract
OBJECTIVE To assess the use of cannabis as a symptom management strategy for patients with fibromyalgia. PATIENTS AND METHODS An electronic, cross-sectional survey was conducted among patients diagnosed with fibromyalgia and treated in Integrative Medicine & Health at Mayo Clinic, Rochester, Minnesota. The survey was constructed with the Symptom Management Theory tool and was sent anonymously via web-based software to patients with a diagnosis of fibromyalgia. RESULTS Of 5234 patients with fibromyalgia sent the online survey, 1336 (25.5%) responded and met the inclusion criteria. Survey respondents had a median age of 48 (Q1-Q3: 37.5-58.0) years, and most identified as female. Nearly half of respondents (49.5%, n=661) reported cannabis use since their fibromyalgia diagnosis. The most common symptoms for which respondents reported using cannabis were pain (98.9%, n=654); fatigue (96.2%; n=636); stress, anxiety, or depression (93.9%; n=621); and insomnia (93.6%; n=619). Improvement in pain symptoms with cannabis use was reported by 82.0% (n=536). Most cannabis-using respondents reported that cannabis also improved symptoms of stress, anxiety, and depression and of insomnia. CONCLUSION Considering that cannabis is a popular choice among patients for managing fibromyalgia symptoms, clinicians should have adequate knowledge of cannabis when discussing therapeutic options for fibromyalgia with their patients.

Abstract
OBJECTIVE Chronic fatigue is a major clinical unmet need among patients with rheumatoid arthritis (RA). Current therapies are limited to nonpharmacological interventions, such as personalized exercise programs (PEPs) and cognitive-behavioral approaches (CBAs); however, most patients still continue to report severe fatigue. To inform more effective therapies, we conducted a magnetic resonance imaging (MRI) brain study of PEPs and CBAs, nested within a randomized controlled trial (RCT), to identify their neurobiological mechanisms of fatigue reduction in RA. METHODS A subgroup of patients with RA (n = 90), participating in an RCT of PEPs and CBAs for fatigue, undertook a multimodal MRI brain scan following randomization to either usual care (UC) alone or in addition to PEPs and CBAs and again after the intervention (six months). Brain regional volumetric, functional, and structural connectivity indices were curated and then computed employing a causal analysis framework. The primary outcome was fatigue improvement (Chalder fatigue scale). RESULTS Several structural and functional connections were identified as mediators of fatigue improvement in both PEPs and CBAs compared to UC. PEPs had a more pronounced effect on functional connectivity than CBAs; however, structural connectivity between the left isthmus cingulate cortex (L-ICC) and left paracentral lobule (L-PCL) was shared, and the size of mediation effect ranked highly for both PEPs and CBAs (ßAverage = -0.46, SD 0.61; ßAverage = -0.32, SD 0.47, respectively). CONCLUSION The structural connection between the L-ICC and L-PCL appears to be a dominant mechanism for how both PEPs and CBAs reduce fatigue among patients with RA. This supports its potential as a substrate of fatigue neurobiology and a putative candidate for future targeting.

Pain neuroscience education improves quality of life when added to aquatic exercise therapy for women with fibromyalgia: randomized controlled clinical trial. Disabil Rehabil 2024; 46:1559-1569. [PMID: 37070715 DOI: 10.1080/09638288.2023.2201510] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2021] [Accepted: 04/06/2023] [Indexed: 04/19/2023]
Abstract
PURPOSE The aim of the present study was to investigate the effects of adding Pain Neuroscience Education (PNE) to an aquatic therapy protocol on pain, fibromyalgia (FMS) impact, quality of life and sleep. MATERIALS AND METHODS Seventy-five women were randomly allocated into two groups: aquatic exercises (AEG, n = 36) and aquatic exercises + PNE (PNG, n = 39). The primary outcome was pain, and the secondary outcomes were FMS impact, quality of life, sleep and pain sensitivity (pressure pain thresholds - PPTs). Participants performed 45-min sessions of aquatic exercises, twice a week, for 12 weeks. PNG also received 4 PNE sessions during this period. Participants were assessed four times: initial (before treatment), after 6 weeks (intermediate) and 12 weeks (final) of treatment and after 12 weeks after the end of treatment (follow-up). RESULTS Both groups improved pain after treatment, with no difference between them (p > 0.05, partial ƞ2 0.10). FMS impact and PPTs improved after treatment with no difference between groups, and sleep did not change. Quality of life improved several domains for both groups, with slightly better results for the PNG, with low effect sizes between groups. CONCLUSIONS The present results show that the addition of PNE to an aquatic exercise intervention did not provide larger effects than aquatic exercises alone for people with FMS concerning pain intensity, but provided benefit for health-related quality of life for this population. TRIAL REGISTRATION ClinicalTrials.gov (NCT03073642, version 2, April 1st, 2019). PERSPECTIVE The addition of 4 Pain Neuroscience Education sessions to an aquatic exercises protocol did not add benefits for women with fibromyalgia syndrome on pain, fibromyalgia impact, and sleep, but improved quality of life and pain sensitivity.IMPLICATIONS FOR REHABILITATIONAquatic exercises are commonly prescribed, but patient education is crucial for the treatment.The addition of Pain Neuroscience Education to an aquatic exercises protocol did not add benefits for women with fibromyalgia syndrome.The positive changes on quality of life and pain sensitivity that this combination led to had small effect sizes and did not achieve minimal important clinical difference.

Significant use of non-evidence-based therapeutics in a cohort of Australian fibromyalgia patients. Intern Med J 2024; 54:568-574. [PMID: 37872879 DOI: 10.1111/imj.16257] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2023] [Accepted: 09/24/2023] [Indexed: 10/25/2023]
Abstract
BACKGROUND Fibromyalgia is a common condition characterised by chronic widespread musculoskeletal pain and central sensitivity features. Appropriate management requires a multidisciplinary approach prioritising non-pharmacological strategies. Evidence-based fibromyalgia medications are not always easily available, effective or tolerated. AIM To characterise actual medication usage in Australian fibromyalgia patients. METHODS Demographic and clinical data, including medication use information, were gathered by chart review from patients attending the Monash Fibromyalgia Clinic between January 2019 and June 2022. Eligible patients were invited to complete an anonymous questionnaire between June and August 2022 to assess current therapeutic use. The questionnaire assessed fibromyalgia clinical features by using the Revised Fibromyalgia Impact Questionnaire and the 2016 modified American College of Rheumatology Fibromyalgia criteria. RESULTS The chart review included 474 patients, and 108 participants completed the questionnaire. Most chart review (78.7%) and questionnaire participants (85.2%) reported using at least one medication for their fibromyalgia. 48.5% of chart review patients and 58.3% of questionnaire participants reported using at least one evidence-based medication, usually amitriptyline, duloxetine or pregabalin. However, the most common individual medications for questionnaire participants were non-steroidal anti-inflammatory drugs (48.2%), paracetamol (59.3%) and opioids (34.3%), with most opioids being typical opioids. Among questionnaire participants, 14.8% reported using cannabinoids, and 70.4% reported using at least one supplement, vitamin or herbal/naturopathic preparation. Not all medication or substance use was recorded during clinic appointments. CONCLUSION Fibromyalgia patients engage in various pharmacotherapeutic strategies that are not always evidence-based or disclosed to their treating clinicians.

Abstract
OBJECTIVES Hench introduced the fibromyalgia syndrome almost 50 years ago. In the meantime, the prevalence has increased, the clinical criteria have changed and the way we explain (chronic) pain has altered. DESIGN In the current study, we conducted a worldwide survey in which we investigate whether medical doctors are familiar with the American College of Rheumatology (ACR) criteria for fibromyalgia and, if so, whether these medical doctors adhere to the clinical guidelines following evidence-based treatments. RESULTS In total, 286 medical doctors from 43 countries spread over 6 continents filled out the survey. In most of the countries, the diagnosis fibromyalgia was used. Only 10% adhere to the ACR criteria, widespread pain (44%), unrefreshed sleep (24%), fatigue (20%) and cognitive problems (8%) were most used diagnostic criteria. Of the respondents, 94 (32%) mentioned that the cause is unknown or idiopathic, but also a wide variety of other causes was mentioned. More than 70 different treatment options were provided, of which 24% of the responses were classified as according to the clinical guidelines. From this study, we conclude that many medical doctors do not follow the ACR criteria; the majority has an inappropriate knowledge of causes for fibromyalgia and that a minority of treatment advice adhere to the guidelines.

Can we achieve pain stratification in musculoskeletal conditions? Implications for clinical practice. FRONTIERS IN PAIN RESEARCH 2024; 5:1362757.

Abstract
In the last few years there has been an increased appreciation that pain perception in rheumatic and musculoskeletal diseases (RMDs) has several mechanisms which include nociceptive, inflammatory, nociplastic and neuropathic components. Studies in specific patient groups have also demonstrated that the pain experienced by people with specific diagnoses can present with distinctive components over time. For example, the pain observed in rheumatoid arthritis has been widely accepted to be caused by the activation of nociceptors, potentiated by the release of inflammatory mediators, including prostaglandins, leukotrienes and cytokine networks in the joint environment. However, people with RA may also experience nociplastic and neuropathic pain components, particularly when treatments with disease modifying anti-rheumatic drugs (DMARDs) have been implemented and are insufficient to control pain symptoms. In other RMDs, the concept of pain sensitisation or nociplastic pain in driving ongoing pain symptoms e.g. osteoarthritis and fibromyalgia, is becoming increasingly recognised. In this review, we explore the hypothesis that pain has distinct modalities based on clinical, pathophysiological, imaging and genetic factors. The concept of pain stratification in RMD is explored and implications for future management are also discussed.

Evaluating the Interaction Between Pain Intensity and Resilience on the Impact of Pain in the Lives of People With Fibromyalgia. Clin J Pain 2024; 40:150-156. [PMID: 37994738 DOI: 10.1097/ajp.0000000000001178] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2023] [Accepted: 11/12/2023] [Indexed: 11/24/2023]
Abstract
OBJECTIVE Recent theoretical models posit that resilience acts as a resource/mechanism opposing pain catastrophizing and other vulnerability sources against pain adaptation. The aim of this study was to investigate the relationship between resilience, pain, and functionality in people living with fibromyalgia (FM). MATERIALS AND METHODS We conducted a cross-sectional online survey of people participating in Brazilian fibromyalgia virtual support groups on Facebook in May 2018. Resilience was evaluated by the Connor-Davidson Resilience Scale. Average pain and the degree of interference of pain in the lives of participants (DIPLP) were assessed using the Brief Pain Inventory. The association between these 3 variables was evaluated through multivariable robust linear regression with adjustment for 21 potential confounders. RESULTS We included 2176 participants with FM. Resilience was associated with a decreased DIPLP (β: -0.38, 95% CI: -0.54 to -0.22, P <0.001) but not with average pain scores (β: -0.01, 95% CI: -0.18 to 0.16, P =0.93). A significant interaction between resilience and average levels of pain on the DIPLP was observed so that resilience showed a much stronger protective association among participants with average null-to-mild pain than among those with moderate and severe pain levels. DISCUSSION Our results provide evidence against beliefs that the pain of people with FM is related to low psychological resilience and shed light on the complex interrelationships between resilience, pain, and functionality. This research signals both the relevance and limits of resilience in the management of FM. Future studies evaluating behavioral interventions for FM should consider how those interventions interact with baseline pain levels and resilience.

Suicidal ideation in female individuals with fibromyalgia and comorbid obesity: prevalence and association with clinical, pain-related, and psychological factors. PAIN MEDICINE (MALDEN, MASS.) 2024; 25:239-247.

Abstract
OBJECTIVE Individuals with fibromyalgia report alarming levels of suicidal ideation, and comorbidity with other chronic health conditions such as obesity-a risk factor for suicidal ideation per se-could further complicate the clinical picture. The aim of this study is to determine, in a sample of women with fibromyalgia and comorbid obesity, the prevalence of suicidal ideation and to evaluate clinical, pain-related and psychological factors associated with suicidal ideation. METHODS In total, 156 female individuals with fibromyalgia and obesity were recruited and completed a series of self-report measures that assessed (i) the level of pain intensity, (ii) depressive symptomatology, (iii) sleep quality, and (iv) pain catastrophizing. Suicidal ideation was evaluated by item #9 of the Beck Depression Inventory. In addition, information regarding previous suicide attempts and current opioid use was collected. RESULTS 3n sum, 7.8% of participants reported presence of suicidal ideation. According to the results of the multiple logistic regression, depressive symptomatology, sleep quality, and pain catastrophizing were associated with the presence of suicidal ideation. DISCUSSION The presence of suicidal ideation in our sample was significantly associated with depressive symptomatology, sleep quality, and pain catastrophizing. Our findings are the first to suggest a unique (ie, independent of depressive symptomatology, and sleep quality) association between pain catastrophizing and suicidal ideation in the context of fibromyalgia and comorbid obesity. In order to prevent and reduce suicidal ideation, these factors should be assessed and targeted in interventions for pain management. Future research should investigate the extent to which addressing depressive symptoms, sleep quality, and pain catastrophizing reduces suicidal ideation.

Machine learning identifies fatigue as a key symptom of fibromyalgia reflected in tyrosine, purine, pyrimidine, and glutaminergic metabolism. Clin Transl Sci 2024; 17:e13740.

Abstract
Fibromyalgia patients vary in clinical phenotype and treatment can be challenging. The pathophysiology of fibromyalgia is incompletely understood but appears to involve metabolic changes at rest or in response to stress. We enrolled 54 fibromyalgia patients and 31 healthy controls to this prospective study. Symptoms were assessed using the Fibromyalgia Impact Questionnaire (FIQ) and blood samples were collected for metabolomics analysis at baseline and after an oral glucose tolerance test and a cardiopulmonary exercise test. We identified key symptoms of fibromyalgia and related them to changes in metabolic pathways with supervised and unsupervised machine learning methods. Algorithms trained with the FIQ information assigned the fibromyalgia diagnosis in new data with balanced accuracy of 88% while fatigue alone already provided the diagnosis with 86% accuracy. Supervised analyses reduced the metabolomic information from 77 to 13 key markers. With these metabolites, fibromyalgia could be identified in new cases with 79% accuracy. In addition, 5-hydroxyindole-3-acetic acid and glutamine levels correlated with the severity of fatigue. Patients differed from controls at baseline in tyrosine and purine pathways, and in the pyrimidine pathway after the stress challenges. Several key markers are involved in glutaminergic neurotransmission. This data-driven analysis highlights fatigue as a key symptom of fibromyalgia. Fibromyalgia is associated with metabolic changes which also reflect the degree of fatigue. Responses to metabolic and physical stresses result in a metabolic pattern that allows discrimination of fibromyalgia patients from controls and narrows the focus on key pathophysiological processes in fibromyalgia as treatment targets.

Abstract
Chronic neck pain (CNP) is a worldwide health problem with several risk factors. One of the most widely used treatments for managing this condition is therapeutic exercise, which could generate a response called exercise-induced hypoalgesia (EIH). There is no consensus on the best exercise modality to induce hypoalgesia. Therefore, this review aims to analyze and synthesize the state-of-the-art about the hypoalgesic effect of exercise in subjects with CNP. We included articles on EIH and CNP in patients older than 18 years, with pain for more than three months, where the EIH response was measured. Articles that studied CNP associated with comorbidities or measured the response to treatments other than exercise were excluded. The studies reviewed reported variable results. Exercise in healthy subjects has been shown to reduce indicators of pain sensitivity; however, in people with chronic pain, the response is variable. Some investigations reported adverse effects with increased pain intensity and decreased pain sensitivity, others found no clinical response, and some even reported EIH with decreased pain and increased sensitivity. EIH is an identifiable, stimulable, and helpful therapeutic response in people with pain. More research is still needed on subjects with CNP to clarify the protocols and therapeutic variables that facilitate the EIH phenomenon. In addition, it is necessary to deepen the knowledge of the intrinsic and extrinsic factors that influence EIH in people with CNP.

Abstract
OBJECTIVE Several types of neuromodulation have been investigated for the treatment of fibromyalgia, but they show varied efficacy on pain, functioning, comorbid depression and comorbid anxiety. Whether some types of neuromodulation or some factors are associated with a better response also awaits clarification. METHODS We conducted a systematic review and network meta-analysis of randomized controlled trials to evaluate the efficacy of neuromodulation in patients with fibromyalgia. We searched PubMed, EMBASE, the Cochrane Central Register of Controlled Trials and PsycINFO before March 2022. We employed a frequentist random-effects network meta-analysis. RESULTS Forty trials involving 1541 participants were included. Compared with sham control interventions, several types of transcranial direct current stimulation (tDCS), transcranial random noise stimulation (tRNS), and high-frequency repetitive transcranial magnetic stimulation (rTMS) were associated with significant reduction of pain, depression, anxiety, and improvement in functioning. Many significantly effective treatment options involve stimulation of the primary motor cortex or dorsolateral prefrontal cortex. CONCLUSION We concluded that several types of rTMS, tDCS and tRNS may have the potential to be applied for clinical purposes.

Whole Body Cryostimulation: A New Adjuvant Treatment in Central Sensitization Syndromes? An Expert Opinion. Healthcare (Basel) 2024; 12:546.

Abstract
Central sensitisation is defined as a multifactorial etiopathogenetic condition involving an increase in the reactivity of nociceptive neurons and alterations in pain transmission and perception in the central nervous system. Patients may present with widespread chronic pain, fatigue, sleep disturbance, dizziness, psychological (e.g., depression, anxiety, and anger) and social impairment. Pain can be spontaneous in onset and persistence, characterised by an exaggerated response and spread beyond the site of origin, and sometimes triggered by a non-painful stimulus. Whole-body cryostimulation (WBC) could be an adjuvant therapy in the management of this type of pain because of its global anti-inflammatory effect, changes in cytokines and hormone secretion, reduction in nerve conduction velocity, autonomic modulation, and release of neurotransmitters involved in the pain pathway. In several conditions (e.g., fibromyalgia, rheumatoid arthritis, and chronic musculoskeletal pain), WBC affects physical performance, pain perception, and psychological aspects. Given its multiple targets and effects at different organs and levels, WBC appears to be a versatile adjuvant treatment for a wide range of conditions of rehabilitation interest. Further research is needed to fully understand the mechanisms of analgesic effect and potential actions on pain pathways, as well as to study long-term effects and potential uses in other chronic pain conditions.

Abstract
BACKGROUND Patients with fibromyalgia experience chronic, widespread pain. It remains a misunderstood disorder with multimodal treatments providing mixed results. OBJECTIVES To examine the effects of radial shockwave therapy (RSWT) compared to placebo on pain, pain catastrophizing, psychological indices, blood markers, and neuroimaging. Study-related experiences were also explored qualitatively. METHODS Quantitative sensory testing (QST), Visual Analog Scale (VAS), Beighton Scoring Screen (BSS), Pain Catastrophizing Scale (PCS), blood biomarker (Interleukin (IL)-6 and IL-10), and brain fMRI were measured pre- and post-treatment along with a post-treatment survey. The RSWT group received five treatments (one week apart over five-week period) to the three most painful areas (500 shocks at 1.5 bar and 15 Hz, then 1000 shocks at 2 bar and 8 Hz, and finally 500 shocks at 1.5 bar and 15 Hz) versus sham treatment for the placebo group. RESULTS There were no statistically significant differences in the BSS for hypermobility (p = .21; d = .74), PCS (p = .70; d = .22), VAS (p = .17-.61; d = .20-.83) scores, QST for skin temperature and stimuli (p = .14-.65; d = .25-.88), and for the pressure pain threshold (p = .71-.93; d = .05-.21). The VAS scores had clinically significant changes (MCID greater than 13.90) with improved pain scores in the RSWT group. Neuroimaging scans revealed no cortical thickness changes. Post-treatment surveys revealed pain and symptom improvements and offered hope to individuals. CONCLUSION RSWT was implemented safely, without any negative treatment effects reported, and acted as a pain modulator to reduce sensitivity. CLINICAL TRIALS REGISTRATION ClinicalTrials.gov identification number NCT02760212.

Abstract
BACKGROUND Opioids are not recommended for fibromyalgia. OBJECTIVE To investigate the frequency of opioid use in a large cohort of fibromyalgia patients and to identify factors associated with opioid consumption. METHODS A retrospective, observational study of a large fibromyalgia cohort in a tertiary care center. We assessed fibromyalgia severity, functional capacity, anxiety, depression, drugs consumption and the patient's impression of change. We compared strong opioid consumers (SOC) and non-SOC. Inferential statistical and logistic regression analysis were used to identify factors associated with opioid consumption, and ANOVA for repeated measurements. RESULTS We found a prevalence of 9.2% of SOC (100 patients) among 1087 patients in the cohort. During the last four years there was a significant increase on the incidence of SOC up to 12.8% (p = 0.004). There were no differences in demographic variables between SOC and non-SOC. Clinical variables were significantly more severe in SOC, and they consumed more non-opioid drugs (p < 0.0001). Opioid consumption was independently associated with other non-opioid drugs (Odds ratio 1.25, CI: 1.13-1.38), but not with the fibromyalgia severity. At three months, 62% of the patients had opioid withdrawal. There were no statistical differences in the fibromyalgia severity at the initial evaluation, or the patient's impression of change compared with those patients who continued opioids. Coping strategies were better in those patients who withdrew opioids (p = 0.044). CONCLUSIONS We observed an increase in opioid prescriptions during the last four years. Opioid consumption was associated with concomitant use of non-opioid drugs, but it was not associated with fibromyalgia severity.

Abstract
OBJECTIVE To assess the burden of illness of people with fibromyalgia (FM) and their spouses compared with selected match populations in Denmark. METHODS Population-based, cohort case-control study using data from Danish registries from 1994 to 2021. Individuals with an FM diagnosis were identified from the National Patient Register (2008-2019) and randomly matched to a 1:4 general population comparator. Spouses or persons co-living with subjects with FM at the time of diagnosis were compared with matched comparator spouses. Healthcare and societal costs, socioeconomic status and occurrence of comorbidities were evaluated for subjects with FM, spouses and controls. RESULTS 9712 subjects with FM (94.9% females, mean age 50 years) and 5946 spouses were included. At year of diagnosis, subjects with FM had significantly more comorbidities compared with controls, including significantly more comorbid rheumatic disorders. The highest risk at the time of FM diagnosis was a comorbid diagnosis of ankylosing spondylitis (OR 7.0, 95% CI 4.9 to 10.0). Significantly more comorbidities were also observed in spouses. Subjects with FM and spouses had higher healthcare and public transfer costs and lower income from employment at all timepoints. Loss of income from employment in subjects with FM occurred years before establishment of the FM diagnosis. The employment rate after diagnosis was 22%. 10 years after the FM diagnosis, 50% received disability pension as compared with 11% of matched controls. The observed net average increased societal cost for subjects with FM amounted to €27 193 per patient-year after diagnosis. CONCLUSION FM has major health and socioeconomic consequences for patients, their partners and society and call for improved healthcare strategies matching patients' needs.

Abstract
BACKGROUND Fibromyalgia (FM) is a chronic disease characterized by widespread pain. Although much is known about this disease, research has focused on diagnosis and treatment, leaving aside factors related to patient's experience and the relationship with healthcare system. OBJECTIVES The aim was to analyze the available evidence on the experience of FM patients from the first symptoms to diagnosis, treatment, and follow-up. METHODS A scoping review was carried out. Medline and the Cochrane Library were searched for original studies or reviews dealing with FM and focusing on "patient journey". Results were organized using a deductive classification of themes. RESULTS Fifty-four articles were included in the qualitative synthesis. Five themes were identified: the patient journey, the challenge for the health systems, a complex doctor-patient relationship, the importance of the diagnosis, and the difficulty of standardizing the treatment. CONCLUSIONS This scoping review confirms the negative impact of FM on the patient, their social environment, and health systems. It is necessary to minimize the difficulties encountered throughout the diagnosis and follow-up of patients with FM.

Abstract
INTRODUCTION The main feature of fibromyalgia syndrome is extensive musculoskeletal pain and tenderness. It not only has a significant impact on patients but also brings a huge burden to families and society. Exercise is considered to be the most important part of the fibromyalgia treatment, and aquatic physical therapy can be considered one of the most recommended interventions. Therefore, the effects of aquatic physical therapy on fibromyalgia patients were discussed in this article. OBJECTIVE The purpose of this study was to evaluate the effects of aquatic physical therapy on clinical symptoms, physical function, and quality of life in patients with fibromyalgia. METHODS Eight databases were retrieved. "Fibromyalgia," "Aquatic Therapy," "Aquatic Exercise," and "Hydrotherapy" was used for retrieval. Randomized controlled trials of the effects of aquatic physical therapy on patients with fibromyalgia were included. The Cochrane risk of bias tool to assess research quality. Meta-analysis was performed by Revman version 5.3. RESULTS Finally, 14 articles (762 patients) were included in the analysis. Compared with other exercises or no exercise, aquatic physical therapy has more significant effects. There were significant differences in visual analogue scale (MD: - 0.98, 95%CI: - 1.36 to - 0.60, Z = 5.03, P < .00001), six minute walk test (MD: 38.12, 95%CI: 13.65 to 62.59, Z = 3.05, P = .002), fibromyalgia impact questionnaire total scores(MD: - 7.35, 95%CI: - 13.05 to - 1.65, Z = 2.53, P = .01), vitality of short form 36 (MD: 9.53, 95%CI: 0.62 to 18.43, Z = 2.10, P = .04) and general health of short form 36 (MD: 10.39, 95%CI: 1.42 to 19.36, Z = 2.27, P = .02). CONCLUSIONS Aquatic physical therapy may have some benefits on the clinical symptoms, physical function, and quality of life of patients with fibromyalgia.

Self-guided digital acceptance and commitment therapy for fibromyalgia management: results of a randomized, active-controlled, phase II pilot clinical trial. J Behav Med 2024; 47:27-42. [PMID: 37382794 PMCID: PMC10867073 DOI: 10.1007/s10865-023-00429-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2022] [Accepted: 05/22/2023] [Indexed: 06/30/2023]
Abstract
Although empirically validated for fibromyalgia (FM), cognitive and behavioral therapies, including Acceptance and Commitment Therapy (ACT), are inaccessible to many patients. A self-guided, smartphone-based ACT program would significantly improve accessibility. The SMART-FM study assessed the feasibility of conducting a predominantly virtual clinical trial in an FM population in addition to evaluating preliminary evidence for the safety and efficacy of a digital ACT program for FM (FM-ACT). Sixty-seven patients with FM were randomized to 12 weeks of FM-ACT (n = 39) or digital symptom tracking (FM-ST; n = 28). The study population was 98.5% female, with an average age of 53 years and an average baseline FM symptom severity score of 8 out of 11. Endpoints included the Fibromyalgia Impact Questionnaire-Revised (FIQ-R) and the Patient Global Impression of Change (PGIC). The between-arm effect size for the change from baseline to Week 12 in FIQ-R total scores was d = 0.44 (least-squares mean difference, - 5.7; SE, 3.16; 95% CI, - 11.9 to 0.6; P = .074). At Week 12, 73.0% of FM-ACT participants reported improvement on the PGIC versus 22.2% of FM-ST participants (P < .001). FM-ACT demonstrated improved outcomes compared to FM-ST, with high engagement and low attrition in both arms. Retrospectively registered at ClinicalTrials.gov (NCT05005351) on August 13, 2021.

Exploring the complexities of pain phenotypes: OMERACT 2023 chronic pain working group workshop. Semin Arthritis Rheum 2024; 64:152342. [PMID: 38128175 DOI: 10.1016/j.semarthrit.2023.152342] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2023] [Revised: 12/06/2023] [Accepted: 12/07/2023] [Indexed: 12/23/2023]
Abstract
OBJECTIVE To educate and discuss pain mechanisms (nociceptive, neuropathic, nociplastic) illuminating its possible impact when measuring different outcomes, which may modify, confound and potentially bias the outcome measures applied across various aspects of Rheumatic Musculoskeletal Diseases (RMDs) clinical trials. METHODS In the plenary presentations, PM lectured on different pain mechanisms and impact on disease activity assessment. Data from two data sets of RMDs patients, which assessed the prevalence and impact of nociplastic pain were presented and reviewed. Audience breakout group sessions and polling were conducted. RESULTS Mixed pain etiologies may differentially influence disease activity assessment and therapeutic decision-making. Polling demonstrated a consensus on the need to assess different types of pain as a phenotype, as it constitutes an important contextual factor (a variable that is not an outcome of the trial, but needs to be recognized [and measured] to understand the study results), and to standardize across RMDs. CONCLUSION There is need for a standardized pain measure that can differentiate underlying pain mechanisms.

Mediating role of physical activity in the relationship between exercise-induced muscle pain and symptom severity in women with fibromyalgia. Physiother Theory Pract 2024; 40:338-346. [PMID: 35968757 DOI: 10.1080/09593985.2022.2111674] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2022] [Accepted: 08/05/2022] [Indexed: 10/15/2022]
Abstract
BACKGROUND Individuals with fibromyalgia (FM) exhibit generalized hyperalgesia to pain stimuli, and physical activity (PA) is critical to manage FM symptoms. PURPOSE This study examined the relationship between exercise-induced muscle pain, symptom severity, and PA in 28 women with FM. METHODS Muscle pain rating (MPR) was assessed during 3 minutes of submaximal isometric handgrip exercise, whereas PA and symptom severity were evaluated via self-report questionnaires. The analysis examined the relationship between the variables, with the specific interest in the mediating role of PA in the relationship between exercise-induced muscle pain and symptom severity. RESULTS MPR was positively associated with symptom severity (b = 1.89; 95% CI = 0.01, 3.76; P = .048) and inversely associated with PA levels (b = -0.16; 95% CI = -0.30, -0.03; P = .021). PA levels were inversely associated with symptom severity (b = -7.94; 95% CI = -12.46, -3.42; P = .001). After statistically controlling for PA levels, the relationship between MPR and symptom severity was no longer significant (b = 0.60; Wald 95% CI = -1.05, 2.25; P = .474). CONCLUSION Results show the link between the variables, and specifically demonstrate that PA mediates the relationship between exercise-induced muscle pain and symptom severity.

Phenotypic characteristics of patients with chronic widespread pain and fibromyalgia: a cross-sectional cluster analysis. Scand J Rheumatol 2024:1-10. [PMID: 38275145 DOI: 10.1080/03009742.2023.2297514] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2023] [Accepted: 12/18/2023] [Indexed: 01/27/2024]
Abstract
OBJECTIVE This study aimed to explore whether phenotypic characteristics of patients with chronic widespread pain (CWP) and fibromyalgia (FM) can be aggregated into definable clusters that may help to tailor treatments. METHOD Baseline variables (sex, age, education, marital/employment status, pain duration, prior CWP/FM diagnosis, concomitant rheumatic disease, analgesics, tender point count, and disease variables derived from standardized questionnaires) collected from 1099 patients (93.4% females, mean age 44.6 years) with a confirmed CWP or FM diagnosis were evaluated by hierarchical cluster analysis. The number of clusters was based on coefficients in the agglomeration schedule, supported by dendrograms and silhouette plots. Simple and multiple regression analyses using all variables as independent predictors were used to assess the likelihood of cluster assignment, reported as odds ratios (ORs) with 95% confidence intervals (CIs). RESULTS Only one cluster emerged (Cluster 1: 455 patients). Participants in this cluster were characterized as working (OR 66.67, 95% CI 7.14 to 500.00), with a medium-term/higher education (OR 16.80, 95% CI 1.94 to 145.41), married/cohabiting (OR 14.29, 95% CI 1.26 to 166.67), and using mild analgesics (OR 25.64, 95% CI 0.58 to > 999.99). The odds of being an individual in Cluster 1 were lower when having a worse score on the PDQ (score ≥ 18) (OR < 0.001, 95% CI < 0.001 to 0.02). CONCLUSION We identified one cluster, where participants were characterized by a potentially favourable clinical profile. More studies are needed to evaluate whether these characteristics could be used to guide the management of patients with CWP and FM.

Diet and Lifestyle Modifications for Fibromyalgia. Curr Rheumatol Rev 2024; 20:CRR-EPUB-137848. [PMID: 38279728 PMCID: PMC11107431 DOI: 10.2174/0115733971274700231226075717] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2023] [Revised: 10/30/2023] [Accepted: 11/08/2023] [Indexed: 01/28/2024]
Abstract
Fibromyalgia (FM) is a complex, widespread pain disorder characterized by symptoms such as fatigue, sleep deprivation, mental fog, mood swings, and headaches. Currently, there are only three FDA-approved medications for FM patients: duloxetine, milnacipran, and pregabalin, with outcomes frequently being inadequate. This research team aims to investigate the effects of diet and lifestyle modifications on FM, with emphasis on anti-inflammatory diet, antioxidants, and gluten-free diets, as well as supplementation with Magnesium, CQ10, and Vitamin D, microbiome, sleep, exercise, and cognitive behavioral therapy. We reviewed the pathophysiology of certain foods that can be proinflammatory with the release of cytokines leading to activation of pain, fatigue and aggravation of the majority of Fibromyalgia symptoms. A literature review was performed by identifying FM articles published between 1994 and 2022 via PubMed and EMBASE databases, with particular emphasis on randomized controlled trials, meta-analysis, and evidence-based treatment guidelines. This review article was completed by a comprehensive narrative review process, in which our team systematically examined relevant scientific literature to provide a comprehensive overview of the significant role that diet and other lifestyle modifications play in mediating symptoms of Fibromyalgia. We propose that diet modifications and lifestyle changes, such as sleep, exercise, and weight loss, can be important steps in managing FM.
