2 Editorial The role of stress in rheumatic diseases. 2010

Hassett, Afton L / Clauw, Daniel J. · ·Arthritis Res Ther · Pubmed #20587002.

ABSTRACT: Rheumatology patients frequently note the occurrence of stressful or traumatic life events prior to the onset of their illness and/or a relationship between stress and disease flares. For our patients, identifying causal events could represent an effort to give meaning to a chronic and often disabling disease, while noting a link between stress and flares may proffer a sense of control. Whatever purpose the report of stress as an etiological or maintaining factor may serve, the science exploring a causal relationship between stress and autoimmune disease onset and course is expanding. Moreover, stress can also induce symptoms such as pain via nonimmunological mechanisms.

ABSTRACT: Fibromyalgia (FM) is a common chronic pain disorder that presents diagnostic challenges for clinicians. Several classification, diagnostic and screening criteria have been developed over the years, but there continues to be a need to develop criteria that reflect the current understanding of FM and are practical for use by clinicians and researchers. The Analgesic, Anesthetic, and Addiction Clinical Trial Translations Innovations Opportunities and Networks (ACTTION) public-private partnership with the U.S. Food and Drug Administration (FDA) and the American Pain Society (APS) initiated the ACTTION-APS Pain Taxonomy (AAPT) to develop a diagnostic system that would be clinically useful and consistent across chronic pain disorders. The AAPT established an international FM working group consisting of clinicians and researchers with expertise in FM to generate core diagnostic criteria for FM and apply the multidimensional diagnostic framework adopted by AAPT to FM. The process for developing the AAPT criteria and dimensions included literature reviews and synthesis, consensus discussions, and analyses of data from large population-based studies conducted in the United Kingdom. The FM working group established a revised diagnosis of FM and identified risk factors, course, prognosis, and pathophysiology of FM. Future studies will assess the criteria for feasibility, reliability, and validity. Revisions of the dimensions will also be required as research advances our understanding of FM. PERSPECTIVE: The ACTTION-APS FM taxonomy provides an evidence-based diagnostic system for FM. The taxonomy includes diagnostic criteria, common features, comorbidities, consequences, and putative mechanisms. This approach might improve the recognition of FM in clinical practice.

4 Review An evidence-based review of pregabalin for the treatment of fibromyalgia. 2018

ABSTRACT: OBJECTIVES: Pregabalin, an α2-δ agonist, is approved for the treatment of fibromyalgia (FM) in the United States, Japan, and 37 other countries. The purpose of this article was to provide an in-depth, evidence-based summary of pregabalin for FM as demonstrated in randomized, placebo-controlled clinical studies, including open-label extensions, meta-analyses, combination studies and post-hoc analyses of clinical study data. METHODS: PubMed was searched using the term "pregabalin AND fibromyalgia" and the Cochrane Library with the term "pregabalin". Both searches were conducted on 2 March 2017 with no other date limits set. RESULTS: Eleven randomized, double-blind, placebo-controlled clinical studies were identified including parallel group, two-way crossover and randomized withdrawal designs. One was a neuroimaging study. Five open-label extensions were also identified. Evidence of efficacy was demonstrated across the studies identified with significant and clinically relevant improvements in pain, sleep quality and patient status. The safety and tolerability profile of pregabalin is consistent across all the studies identified, including in adolescents, with dizziness and somnolence the most common adverse events reported. These efficacy and safety data are supported by meta-analyses (13 studies). Pregabalin in combination with other pharmacotherapies (7 studies) is also efficacious. Post-hoc analyses have demonstrated the onset of pregabalin efficacy as early as 1-2 days after starting treatment, examined the effect of pregabalin on other aspects of sleep beyond quality, and shown it is effective irrespective of the presence of a wide variety of patient demographic and clinical characteristics. CONCLUSIONS: Pregabalin is a treatment option for FM; its clinical utility has been comprehensively demonstrated.

ABSTRACT: Fibromyalgia (FM) is a complex chronic disease that affects 3-10% of the general adult population and is principally characterized by widespread pain, and is often associated with disrupted sleep, fatigue, and comorbidities, among other symptoms. There are many gaps in our knowledge of FM, such that, compared with other chronic illnesses including diabetes, rheumatoid arthritis, and asthma, it is far behind in terms of provider understanding and therapeutic approaches. The experience that healthcare professionals (HCPs) historically gained in developing approaches to manage and treat patients with these chronic illnesses may help show how they can address similar problems in patients with FM. In this review, we examine some of the issues around the management and treatment of FM, and discuss how HCPs can implement appropriate strategies for the benefit of patients with FM. These issues include understanding that FM is a legitimate condition, the benefits of prompt diagnosis, use of non-drug and pharmacotherapies, patient and HCP education, watchful waiting, and assessing patients by FM domain so as not to focus exclusively on one symptom to the detriment of others. Developing successful approaches is of particular importance for HCPs in the primary care setting who are in the ideal position to provide long-term care for patients with FM. In this way, FM may be normalized as a chronic illness to the benefit of both patients and HCPs.

ABSTRACT: INTRODUCTION: The mechanism of sensitization of the central nervous system partly explains the chronic pain experience in many patients, but the etiological mechanisms of this central nervous system dysfunction are poorly understood. Recently, an increasing number of studies suggest that aberrant glial activation takes part in the establishment and/or maintenance of central sensitization. Areas covered: This review focused on preclinical work and mostly on the neurobiochemistry studied in animals, with limited human studies available. Glial overactivation results in a low-grade neuroinflammatory state, characterized by high levels of BDNF, IL-1β, TNF-α, which in turn increases the excitability of the central nervous system neurons through mechanisms like long-term potentiation and increased synaptic efficiency. Aberrant glial activity in chronic pain might have been triggered by severe stress exposure, and/or sleeping disturbances, each of which are established initiating factors for chronic pain development. Expert opinion: Potential treatment avenues include several pharmacological options for diminishing glial activity, as well as conservative interventions like sleep management, stress management and exercise therapy. Pharmacological options include propentofylline, minocycline, β -adrenergic receptor antagonists, and cannabidiol. Before translating these findings from basic science to clinical settings, more human studies exploring the outlined mechanisms in chronic pain patients are needed.

7 Review Challenges of implementing fibromyalgia treatment guidelines in current clinical practice. 2017

ABSTRACT: The current diagnostic and treatment pathway for patients with fibromyalgia (FM) is lengthy, complex, and characterized by multiple physician visits with an average 2-year wait until diagnosis. It is clear that effective identification and appropriate treatment of FM remain a challenge in current clinical practice. Ideally, FM management involves a multidisciplinary approach with the preferable patient pathway originating in primary care but supported by a range of health care providers, including referral to specialist care when necessary. After the publication of individual clinical studies, high-quality reviews, and meta-analyses, recently published FM treatment guidelines have transitioned from an expert consensus to an evidence-based approach. Evidence-based guidelines provide a framework for ensuring early diagnosis and timely adoption of appropriate treatment. However, for successful outcomes, FM treatments must adopt a more holistic approach, which addresses more than just pain. Impact on the associated symptoms of fatigue and cognitive problems, sleep and mood disturbances, and lowered functional status are also important in judging the success of FM therapy. Recently published guidelines recommend the adoption of a symptom-based approach to guide pharmacologic treatment. Emerging treatment options for FM may be best differentiated on the basis of their effect on comorbid symptoms that are often associated with pain (e.g. sleep disturbance, mood, fatigue). The current review discusses the most recently published Canadian guidelines and the implications of the recent European League Against Rheumatism (EULAR) recommendations, with a focus on the challenges of implementing these guidelines in current clinical practice.

9 Review Neurobiology of fibromyalgia and chronic widespread pain. 2016

Sluka, Kathleen A / Clauw, Daniel J. ·Physical Therapy and Rehabilitation Science, Pain Research Program, University of Iowa, United States.

ABSTRACT: Fibromyalgia is the current term for chronic widespread musculoskeletal pain for which no alternative cause can be identified. The underlying mechanisms, in both human and animal studies, for the continued pain in individuals with fibromyalgia will be explored in this review. There is a substantial amount of support for alterations of central nervous system nociceptive processing in people with fibromyalgia, and that psychological factors such as stress can enhance the pain experience. Emerging evidence has begun exploring other potential mechanisms including a peripheral nervous system component to the generation of pain and the role of systemic inflammation. We will explore the data and neurobiology related to the role of the CNS in nociceptive processing, followed by a short review of studies examining potential peripheral nervous system changes and cytokine involvement. We will not only explore the data from human subjects with fibromyalgia but will relate this to findings from animal models of fibromyalgia. We conclude that fibromyalgia and related disorders are heterogenous conditions with a complicated pathobiology with patients falling along a continuum with one end a purely peripherally driven painful condition and the other end of the continuum is when pain is purely centrally driven.

ABSTRACT: Chronic pain substantially impacts patient function and quality of life and is a burden to society at large in terms of increased health care utilization and loss of productivity. As a result, there is an increasing recognition of chronic pain as a public health crisis. However, there remains wide variability in clinical practices related to the prevention, assessment, and treatment of chronic pain. Certain fundamental aspects of chronic pain are often neglected including the contribution of the psychological, social, and contextual factors associated with chronic pain. Also commonly overlooked is the importance of understanding the likely neurobiological mechanism(s) of the presenting pain and how they can guide treatment selection. Finally, physicians may not recognize the value of using electronic medical records to systematically capture data on pain and its impact on mood, function, and sleep. Such data can be used to monitor onset and maintenance of treatments effects at the patient level and evaluate costs at the systems level. In this review we explain how these factors play a critical role in the development of a coordinated, evidence-based treatment approach tailored to meet specific needs of the patient. We also discuss some practical approaches and techniques that can be implemented by clinicians in order to enhance the assessment and management of individuals with chronic pain in primary care settings.

11 Review Opioid Use in Fibromyalgia: A Cautionary Tale. 2016

Goldenberg, Don L / Clauw, Daniel J / Palmer, Roy E / Clair, Andrew G. ·Department of Medicine, Tufts University School of Medicine, Boston, MA. Electronic address: dongoldenberg44@gmail.com. · Department of Anesthesiology, University of Michigan, Ann Arbor. · Pfizer Inc, New York, NY. ·Mayo Clin Proc · Pubmed #26975749.

ABSTRACT: Multiple pharmacotherapies are available for the treatment of fibromyalgia (FM), including opioid analgesics. We postulate that the mechanism of action of traditional opioids predicts their lack of efficacy in FM. Literature searches of the MEDLINE and Cochrane Library databases were conducted using the search term opioid AND fibromyalgia to identify relevant articles, with no date limitations set. Citation lists in returned articles and personal archives of references were also examined for additional relevant items, and articles were selected based on the expert opinions of the authors. We found no evidence from clinical trials that opioids are effective for the treatment of FM. Observational studies have found that patients with FM receiving opioids have poorer outcomes than patients receiving nonopioids, and FM guidelines recommend against the use of opioid analgesics. Despite this, and despite the availability of alternative Food and Drug Administration-approved pharmacotherapies and the efficacy of nonpharmacologic therapies, opioids are commonly used in the treatment of FM. Factors associated with opioid use include female sex; geographic variation; psychological factors; a history of opioid use, misuse, or abuse; and patient or physician preference. The long-term use of opioid analgesics is of particular concern in the United States given the ongoing public health emergency relating to excess prescription opioid consumption. The continued use of opioids to treat FM despite a proven lack of efficacy, lack of support from treatment guidelines, and the availability of approved pharmacotherapy options provides a cautionary tale for their use in other chronic pain conditions.

12 Review Diagnosing and treating chronic musculoskeletal pain based on the underlying mechanism(s). 2015

Clauw, Daniel J. ·Chronic Pain and Fatigue Research Center, The University of Michigan, 24 Frank Lloyd Wright Dr PO Box 385, Ann Arbor, MI 48106, USA. Electronic address: dclauw@umich.edu. ·Best Pract Res Clin Rheumatol · Pubmed #26266995.

ABSTRACT: Until recently, most clinicians considered chronic pain to be typically due to ongoing peripheral nociceptive input (i.e., damage or inflammation) in the region of the body where the individual is experiencing pain. Clinicians are generally aware of a few types of pain (e.g., headache and phantom limb pain) where chronic pain is not due to such causes, but most do not realize there is not a single chronic pain state where any radiographic, surgical, or pathological description of peripheral nociceptive damage has been reproducibly shown to be related to the presence or severity of pain. The primary reason for this appears to be that both the peripheral and central nervous systems play a critical role in determining which nociceptive input being detected by sensory nerves in the peripheral tissues will lead to the perception of pain in humans. This manuscript reviews some of the latest findings regarding the neural processing of pain, with a special focus on how clinicians can use information gleaned from the history and physical examination to assess which mechanisms are most likely to be responsible for pain in a given individual, and tailors therapy appropriately. A critical construct is that, within any specific diagnostic category (e.g., fibromyalgia (FM), osteoarthritis (OA), and chronic low back pain (CLBP) are specifically reviewed), individual patients may have markedly different peripheral/nociceptive and neural contributions to their pain. Thus, just as low back pain has long been acknowledged to have multiple potential mechanisms, so also is this true of all chronic pain states, wherein some individuals will have pain primarily due to peripheral nociceptive input, whereas in others peripheral (e.g., peripheral sensitization) or central nervous system factors ("central sensitization" or "centralization" of pain via augmented pain processing in spinal and brain) may be playing an equally or even more prominent role in their pain and other symptoms.

13 Review Premature Aging in Fibromyalgia. 2015

Hassett, Afton L / Clauw, Daniel J / Williams, David A. ·Department of Anesthesiology, University of Michigan Medical School, Chronic Pain & Fatigue Research Center, Domino's Farms, Lobby M, P.O Box 385, 24 Frank Lloyd Wright Drive, Ann Arbor, MI 48106, USA. afton@med.umich.edu. ·Curr Aging Sci · Pubmed #26212052.

ABSTRACT: Chronic pain is highly prevalent in older adults, and until recently, was considered to be common but relatively "benign." Mounting evidence, however, suggests that some of the 116 million US adults who suffer from chronic pain are also at an increased risk for developing age-related diseases prematurely, suffering earlier cognitive and physical decline, and experiencing earlier mortality. Given the aging US population and the prevalence of chronic pain along with related healthcare consequences, there is a critical need to better understand the relationship between aging and chronic pain. Herein, we focus on one chronic pain state, fibromyalgia, and provide an overview of the evidence suggesting that individuals with this chronic pain condition show signs of premature aging.

14 Review Fibromyalgia and related conditions. 2015

Clauw, Daniel J. ·University of Michigan, Ann Arbor, MI. Electronic address: dclauw@med.umich.edu. ·Mayo Clin Proc · Pubmed #25939940.

ABSTRACT: Fibromyalgia is the currently preferred term for widespread musculoskeletal pain, typically accompanied by other symptoms such as fatigue, memory problems, and sleep and mood disturbances, for which no alternative cause can be identified. Earlier there was some doubt about whether there was an "organic basis" for these related conditions, but today there is irrefutable evidence from brain imaging and other techniques that this condition has strong biological underpinnings, even though psychological, social, and behavioral factors clearly play prominent roles in some patients. The pathophysiological hallmark is a sensitized or hyperactive central nervous system that leads to an increased volume control or gain on pain and sensory processing. This condition can occur in isolation, but more often it co-occurs with other conditions now being shown to have a similar underlying pathophysiology (eg, irritable bowel syndrome, interstitial cystitis, and tension headache) or as a comorbidity in individuals with diseases characterized by ongoing peripheral damage or inflammation (eg, autoimmune disorders and osteoarthritis). In the latter instance, the term centralized pain connotes the fact that in addition to the pain that might be caused by peripheral factors, there is superimposed pain augmentation occurring in the central nervous system. It is important to recognize this phenomenon (regardless of what term is used to describe it) because individuals with centralized pain do not respond nearly as well to treatments that work well for peripheral pain (surgery and opioids) and preferentially respond to centrally acting analgesics and nonpharmacological therapies.

15 Review Fibromyalgia: a clinical review. 2014

Clauw, Daniel J. ·Professor of Anesthesiology, Medicine (Rheumatology), and Psychiatry and Director, Chronic Pain and Fatigue Research Center, University of Michigan, Ann Arbor. ·JAMA · Pubmed #24737367.

ABSTRACT: IMPORTANCE: Fibromyalgia is present in as much as 2% to 8% of the population, is characterized by widespread pain, and is often accompanied by fatigue, memory problems, and sleep disturbances. OBJECTIVE: To review the epidemiology, pathophysiology, diagnosis, and treatment of fibromyalgia. EVIDENCE REVIEW: The medical literature on fibromyalgia was reviewed from 1955 to March 2014 via MEDLINE and the Cochrane Central Registry of Controlled Trials, with an emphasis on meta-analyses and contemporary evidence-based treatment guidelines. Treatment recommendations are based on the most recent evidence-based guidelines from the Canadian Pain Society and graded from 1 to 5 based on the level of available evidence. FINDINGS: Numerous treatments are available for managing fibromyalgia that are supported by high-quality evidence. These include nonpharmacological therapies (education, exercise, cognitive behavioral therapy) and pharmacological therapies (tricyclics, serotonin norepinephrine reuptake inhibitors, and gabapentinoids). CONCLUSIONS AND RELEVANCE: Fibromyalgia and other "centralized" pain states are much better understood now than ever before. Fibromyalgia may be considered as a discrete diagnosis or as a constellation of symptoms characterized by central nervous system pain amplification with concomitant fatigue, memory problems, and sleep and mood disturbances. Effective treatment for fibromyalgia is now possible.

16 Review A framework for fibromyalgia management for primary care providers. 2012

Arnold, Lesley M / Clauw, Daniel J / Dunegan, L Jean / Turk, Dennis C / Anonymous2450725. ·Department of Psychiatry and Behavioral Neuroscience and the Women's Health Research Program, University of Cincinnati College of Medicine, OH 45219, USA. Lesley.Arnold@uc.edu ·Mayo Clin Proc · Pubmed #22560527.

ABSTRACT: Fibromyalgia is a chronic widespread pain disorder commonly associated with comorbid symptoms, including fatigue and nonrestorative sleep. As in the management of other chronic medical disorders, the approach for fibromyalgia management follows core principles of comprehensive assessment, education, goal setting, multimodal treatment including pharmacological (eg, pregabalin, duloxetine, milnacipran) and nonpharmacological therapies (eg, physical activity, behavioral therapy, sleep hygiene, education), and regular education and monitoring of treatment response and progress. Based on these core management principles, this review presents a framework for primary care providers through which they can develop a patient-centered treatment program for patients with fibromyalgia. This proactive and systematic treatment approach encourages ongoing education and patient self-management and is designed for use in the primary care setting.

17 Review Central pain mechanisms in chronic pain states--maybe it is all in their head. 2011

Phillips, Kristine / Clauw, Daniel J. ·University of Michigan, Ann Arbor, MI, United States. kphill@med.umich.edu ·Best Pract Res Clin Rheumatol · Pubmed #22094191.

ABSTRACT: Mechanisms underlying chronic pain differ from those underlying acute pain. In chronic pain states, central nervous system (CNS) factors appear to play particularly prominent roles. In the absence of anatomical causes of persistent pain, medical sub-specialities have historically applied wide-ranging labels (e.g., fibromyalgia (FM), irritable bowel syndrome, interstitial cystitis and somatisation) for what now is emerging as a single common set of CNS processes. The hallmark of these 'centrally driven' pain conditions is a diffuse hyperalgesic state identifiable using experimental sensory testing, and corroborated by functional neuroimaging. The characteristic symptoms of these central pain conditions include multifocal pain, fatigue, insomnia, memory difficulties and a higher rate of co-morbid mood disorders. In contrast to acute and peripheral pain states that are responsive to non-steroidal anti-inflammatory drugs (NSAIDs) and opioids, central pain conditions respond best to CNS neuromodulating agents, such as serotonin-norepinephrine reuptake inhibitors (SNRIs) and anticonvulsants.

19 Review Fibromyalgia: a primer for the anesthesia community. 2011

Brummett, Chad M / Clauw, Daniel J. ·Department of Anesthesiology, University of Michigan Health System, Ann Arbor, Michigan, USA. cbrummet@umich.edu ·Curr Opin Anaesthesiol · Pubmed #21799404.

ABSTRACT: PURPOSE OF REVIEW: The present review is intended to give an overview of fibromyalgia for the anesthesiologist. While the basics of the treatment of fibromyalgia are included, the intent is to provide context to discuss the potential implications in perioperative management. RECENT FINDINGS: Research continues to demonstrate that fibromyalgia patients have neurophysiologic abnormalities that alter sensory perception, including lower levels of central neurotransmitters associated with the inhibition of pain and higher levels those that facilitate pain. While comorbid mood disorders are more common in fibromyalgia patients, studies have shown that fibromyalgia symptoms are not explained by depression alone. In the last year, the American College of Rheumatology established a new self-report questionnaire for the diagnosis of fibromyalgia in lieu of the previously required tender point examination plus self-report questionnaire. This questionnaire allows for the study of the severity of sensitivity and symptomatology on a continuum, which is termed 'fibromyalgianess'. Some new concepts in the treatment have been proposed, including sodium oxybate, transcranial magnetic stimulation, and web-based cognitive behavioral therapy. SUMMARY: The impact of fibromyalgia on anesthesia care is not known. Years of quality research have clearly demonstrated multiple pathophysiologic changes that could impact anesthesia care and future study is needed.

20 Review Fibromyalgia: from pathophysiology to therapy. 2011

Schmidt-Wilcke, Tobias / Clauw, Daniel J. ·Chronic Pain and Fatigue Research Center, Department of Anesthesiology, University of Michigan, Ann Arbor, 48106, USA. tobiass@ med.umich.edu ·Nat Rev Rheumatol · Pubmed #21769128.

ABSTRACT: Individuals with fibromyalgia generally experience chronic widespread pain, which can be accompanied by further symptoms including fatigue, sleep disturbances, cognitive dysfunction, anxiety and depressive episodes. As the recognition and diagnosis of fibromyalgia has improved, the availability of therapeutic options for patients has increased. Furthermore, research into the neurobiological mechanisms that contribute to the chronic pain and concomitant symptoms experienced by patients with fibromyalgia has advanced our understanding of this debilitating disorder. In this Review, we aim to provide an overview of existing pathophysiological concepts. The roles of biological and psychological stress, genetic factors, and pain and sensory processing in the pathophysiology of fibromyalgia and related conditions are discussed. In addition, pharmacological treatments, including monoamine modulators, calcium channel modulators and γ-aminobutyric acid modulators, as well as nonpharmacological treatment options are considered.

21 Review The role of the central nervous system in the generation and maintenance of chronic pain in rheumatoid arthritis, osteoarthritis and fibromyalgia. 2011

Lee, Yvonne C / Nassikas, Nicholas J / Clauw, Daniel J. ·Division of Rheumatology, Immunology and Allergy, Brigham and Women's Hospital, 75 Francis Street, PBB-B3, Boston, MA 02115, USA. ylee9@partners.org ·Arthritis Res Ther · Pubmed #21542893.

ABSTRACT: Pain is a key component of most rheumatologic diseases. In fibromyalgia, the importance of central nervous system pain mechanisms (for example, loss of descending analgesic activity and central sensitization) is well documented. A few studies have also noted alterations in central pain processing in osteoarthritis, and some data, including the observation of widespread pain sensitivity, suggest that central pain-processing defects may alter the pain response in rheumatoid arthritis patients. When central pain is identified, different classes of analgesics (for example, serotonin-norepinephrine reuptake inhibitors, α2δ ligands) may be more effective than drugs that treat peripheral or nociceptive pain (for example, nonsteroidal anti-inflammatory drugs and opioids).

22 Review Improving the recognition and diagnosis of fibromyalgia. 2011

Arnold, Lesley M / Clauw, Daniel J / McCarberg, Bill H / Anonymous1720693. ·Department of Psychiatry and Behavioral Neuroscience and the Women's Health Research Program, University of Cincinnati College of Medicine, Cincinnati, OH, USA. lesley.arnold@uc.edu ·Mayo Clin Proc · Pubmed #21531887.

ABSTRACT: Fibromyalgia (FM) is a chronic widespread pain disorder often seen in primary care practices. Advances in the understanding of FM pathophysiology and clinical presentation have improved the recognition and diagnosis of FM in clinical practice. Fibromyalgia is a clinical diagnosis based on signs and symptoms and is appropriate for primary care practitioners to make. The hallmark symptoms used to identify FM are chronic widespread pain, fatigue, and sleep disturbances. Awareness of common mimics of FM and comorbid disorders will increase confidence in establishing a diagnosis of FM.

23 Review Fibromyalgia: an afferent processing disorder leading to a complex pain generalized syndrome. 2011

Smith, Howard S / Harris, Richard / Clauw, Daniel. ·Albany Medical College, Department of Anesthesiology, Albany, NY 12208, USA. smithh@mail.amc.edu ·Pain Physician · Pubmed #21412381.

ABSTRACT: Fibromyalgia is a condition which appears to involve disordered central afferent processing. The major symptoms of fibromyalgia include multifocal pain, fatigue, sleep disturbances, and cognitive or memory problems. Other symptoms may include psychological distress, impaired functioning, and sexual dysfunction. The pathophysiology of fibromyalgia remains uncertain but is believed to be largely central in nature. In 1990 the American College of Rheumatology (ACR) published diagnostic research criteria for fibromyalgia. The criteria included a history of chronic and widespread pain and the presence of 11 or more out of 18 tender points. Pain was considered chronic widespread when all of the following are present: pain in the left side of the body; pain in the right side of the body; pain above the waist; pain below the waist. In addition, axial skeletal pain must be present and the duration of pain must be more than 3 months. A tender point is considered positive when pain can be elicited by pressures of 4 kg/cm2 or less. For tender points to be considered positive, the patient must perceive the palpation as painful; tenderness to palpation is not sufficient. However, over the next 20 years it became increasingly appreciated that the focus on tender points was not justified. In 2010 a similar group of investigators performed a multicenter study of 829 previously diagnosed fibromyalgia patients and controls using physician physical and interview examinations, including a widespread pain index (WPI), a measure of the number of painful body regions. Random forest and recursive partitioning analyses were used to guide the development of a case definition of fibromyalgia, to develop new preliminary ACR diagnostic criteria, and to construct a symptom severity (SS) scale. The most important diagnostic variables were WPI and categorical scales for cognitive symptoms, un-refreshed sleep, fatigue, and number of somatic symptoms. The categorical scales were summed to create an SS scale. The investigators combined the SS scale and the WPI to recommend a new case definition of fibromyalgia: (WPI > or = 7 AND SS > or = 5). Although there is no known cure for fibromyalgia, multidisciplinary team efforts using combined treatment approaches, including patient education, aerobic exercise, cognitive behavioral therapy, and pharmacologic therapies (serotonin norepinephrine reuptake inhibitors [e.g., duloxetine, milnacipran] and alpha 2-delta receptor ligands [e.g., pregabalin]) might improve symptoms as well as function in patients with fibromyalgia.

ABSTRACT: Fatigue is a symptom whose causes are protean and whose phenotype includes physical, mood, and behavioral components. Chronic fatigue syndrome (CFS) is an illness that has strong biological underpinnings and no definite etiology. Diagnostic criteria established by the Centers for Disease Control and Prevention have helped classify CFS as an overlap of mood, behavioral, and biological components. These include the presence of fatigue for more than 6 months associated with a diminution of functional activity and somatic symptoms, and pain not attributable to a specific diagnosis or disease. Four of the following criteria need to be present: sore throat, impaired memory or cognition, unrefreshing sleep, postexertional fatigue, tender glands, aching stiff muscles, joint pain, and headaches. Many researchers have observed that CFS shares features in common with other somatic syndromes, including irritable bowel syndrome, fibromyalgia, and temporomandibular joint dysfunction. Correlations between inflammation and infection, augmented sensory processing, abnormalities of neurotransmitters, nerve growth factors, low levels of serotonin and norepinephrine, abnormalities of homeostasis of the stress system, and autonomic dysfunction may be hallmarks of CFS. The relative contributions of each of these abnormalities to the profound fatigue associated with CFS need to be explored further to better evaluate and treat the syndrome.

25 Review Pharmacotherapy in fibromyalgia (FM)--implications for the underlying pathophysiology. 2010

ABSTRACT: Although chronic pain states are highly prevalent, the underlying neurobiological mechanisms involved in causing pain are incompletely understood. This is especially true for the so-called chronic functional pain syndromes and pain syndromes of unknown origin, such as fibromyalgia (FM), in which no structural correlates of pain experience, in terms of a nociceptive source, can clearly be defined. In addition to limited therapeutic options and often unsatisfactory treatment, such patients often struggle with socio-medical acceptance of their pain condition. As FM has become more widely recognized, options available for treatment have grown along with our understanding of the neurobiological mechanisms underlying chronic pain experience and concomitant symptoms. The current review aims to provide an overview of existing pharmacotherapies for FM, and their implication for the underlying pathophysiology. Further we discuss some of the potential targets that have been recently identified that may hold promise for the development of novel treatments.
