Active clinical trials for "Fibromyalgia"

Fibromyalgia (FM) is a very common but mysterious pain disorder characterized by chronic widespread muscular pain. Fatigue, anxiety and depression are common comorbidities. The syndrome is commonly associated with several symptoms, including fatigue, sleeping disturbance, cognitive impairment, and comorbid pain syndrome, especially irritable bowel symptoms and temporomandibular disease. Anxiety and depression are common psychiatric co-morbidies. Daily stress is believed to trigger or aggravate pain conditions. These symptoms can markedly affect patients' quality of life, and even lead to disability. So far, the etiology and pathogenesis are largely unknown, and diagnostic biomarkers and curative treatment remain to be developed. Recent technological advances enable scientists to explore mechanisms by genetic, transcriptomic, proteomic, and metabolomic researches. However, no definitive result has been concluded for clinical practice so far. In this study, the investigators use tailored questionnaires to evaluate fibromyalgia and associated symptoms, including numeric rating scale for soreness, widespread soreness index, Fibromyalgia impact questionnaire, Hospital Anxiety and Depression Scale, and perceived stress scale. The investigators also use metabolomics and lipidomic approach to probe the potential pathophysiology of fibromyalgia. In our prior translation research (PMID: 32907805), the investigators found that excessive LPC16:0 resulting from lipid oxidization inflicts psychological stress-induced chronic non-inflammatory pain via activating ASIC3. In this content, our prior translational research identified a potential nociceptive ligand that causes fibromyalgia symptoms, which is likely to function as biomarkers for diagnosis or disease monitor. In the current clinical investigation, the investigators aim to reversely translate the novel findings in animal studies and validate the bio-significance of LPC16:0 for fibromyalgia with clinical approaches.

To collect, preserve, and/or distribute annotated biospecimens and associated medical data to institutionally approved, investigator-directed biomedical research to discover and develop new treatments, diagnostics, and preventative methods for specific and complex conditions.

The goal of this observational study is to test for behavioural and neurophysiological biomarkers in fibromyalgia patients. The main questions it aims to answer are: Is there a measurable decline in working memory? Could these measures help in fibromyalgia differential diagnosis? Participants will: perform Color Comparison tasks perform n-back tasks

The Savella Pregnancy Registry is a US based registry designed to monitor pregnancies exposed to Savella (milnacipran HCI). This is an observational, exposure-registration and follow-up registry designed primarily to estimate the prevalence of major congenital anomalies, and secondarily to estimate the prevalence of recognized spontaneous abortions, stillbirths, induced abortions, minor congenital anomalies, and any serious adverse pregnancy outcomes among pregnancies exposed to Savella as well as adverse outcomes observed during the first year of life in off-springs born from these exposed pregnancies. Live offspring are followed from birth until age one. The Savella Pregnancy Registry is sponsored by AbbVie (formerly Actavis PLC, Forest Laboratories Inc., and Allergan) and managed by Syneos Health.

Fibromyalgia Syndrome (FMS) is a complex syndrome that mainly includes the musculoskeletal system and is characterized by many symptoms such as chronic widespread pain, fatigue and sleep disorders, cognitive dysfunctions, regional pain syndrome, psychiatric disorders. The existence and importance of the multidimensional nature of chronic pain in FMS has been demonstrated. Factors such as pain intensity, persistence of pain, pain-related disability, and novelty of onset are all important characteristics of a chronic pain condition. Therefore, there was a need for a global measure of chronic pain severity that summarized different measures of pain and a graded classification of chronic pain was proposed. Patients with chronic pain such as FMS are known to have a greater negative impact than many chronic medical conditions. Chronic pain severity in FMS has been found to be associated with various conditions such as function and health status, and it has been shown that reduction in pain severity provides broadly beneficial results on these conditions. However; there are no studies in which chronic pain severity in FMS is classified by grading and investigating the relationship of different pain severity degrees with disease severity and other symptoms. The aim of this study is to evaluate whether the severity of the disease, kinesiophobia, and concerns about pain differ in individuals with different pain severity by grading the severity of pain in individuals with fibromyalgia syndrome.

This experimental study will investigate whether the decreased NFR threshold and increased NFR temporal summation, which are frequently observed in chronic pain patients, are only symptomatic manifestations that occur in the involved limb and indicate peripheral sensitization or generalized manifestations that are also present in the non-involved limbs and thus indicate central sensitization. To gain an idea of the presence of central sensitization, this study will also investigate whether there are increased perception and decreased pain thresholds in response to electrical, thermal, and mechanical stimulation, as well as whether there is a decreased conditioned pain modulation. To investigate this, it is essential to examine different pain populations and locations, in particular, acute pain versus chronic pain populations to compare peripheral versus central sensitization, respectively. Recently, our research group has shown that patients with a traumatic origin of chronic neck pain (chronic whiplash-associated disorders) show central sensitization in contrast to patients with a non-traumatic origin (chronic idiopathic neck pain) who demonstrate only indications for peripheral sensitization. Therefore, this study will also distinguish between complaints of traumatic and non-traumatic origin. The measurements will be performed at different locations, namely the lower and upper limbs. To determine whether the differences depend on the measurement location (= location where experimental nociceptive stimulation is administered) and symptom location (= location of clinical nociceptive stimulation), different patient populations will be compared with each other, as well as with a healthy control population. In acute and chronic whiplash patients and patients with acute and chronic idiopathic neck pain complaints, the complaints are primarily localized in the upper limb. It is hypothesized that in chronic neck pain patients (both whiplash and idiopathic neck pain patients) abnormal values are found in both the upper and lower limbs compared to the healthy controls due to central sensitization. In acute neck pain patients (both whiplash and idiopathic neck pain) only abnormal values in the arm are expected and not in the leg as a result of peripheral sensitization. It is hypothesized that patients with neck pain of traumatic origin will show a stronger sensitization than those with neck pain of non-traumatic origin. In acute and chronic low back pain patients, the complaints are primarily localized in the lower body quadrant. As a result of central sensitization in the chronic low back pain patients, abnormal values are expected in both the upper and lower limbs, while only abnormal values in the leg are expected as a result of peripheral sensitization in the acute low back pain patients. Finally, this study will investigate whether chronic low back and neck pain patients show a similar pattern of central sensitization as fibromyalgia patients, a population with generalized complaints that are primarily attributed to central sensitization.

Fibromyalgia (FM) is a chronic musculoskeletal pain disorder that afflicts up to 4% of the general population. The evaluation of pain mechanisms in FM has shown predominant central abnormalities and therefore has been designated as nociplastic pain syndrome. Rheumatoid arthritis (RA) is characterized by polyarthritis and pain from inflamed tissues, consistent with nociceptive pain. FM and RA patients may utilize overlapping pain mechanisms resulting in nociceptive and nociplastic pain.

Numerous studies reported on comorbidity of fibromyalgia and psychiatric disorders. Approximately 30% of patients with fibromyalgia have major depression at the time of diagnosis; the lifetime prevalence of depression is 74% and that of an anxiety disorder is 60%. In some fibromyalgia patients, mood and cognitive problems are much more prominent than tenderness. From the psychiatric point of view, 49% of PTSD patients and 5% of major depression patients fulfill criteria for diagnosing fibromyalgia. The association between schizophrenia and fibromyalgia is still unknown. Study hypothesis Schizophrenia patients, who have an aberrant sensation of pain, have lower prevalence of FM compared to the general population. Primary objectives Demonstrate that schizophrenia patients have lower prevalence of FM, compared to the general population. To compare the self-reported extent and intensity of pain with selected tender points examination.

Psychological distress (anxiety and depression) is common in and experienced differently by people living with long-term health conditions (LTCs). Being able to measure whether psychological distress is related to living with a LTC would allow researchers and clinicians to provide interventions specifically tailored to the challenges of living with a LTC and therefore provide the most appropriate support for these patients. Such a measure would also be useful in research to identify the presence of illness-related distress in different patient groups. This project will therefore create a new measure of illness-related distress that has applications for both research and clinical practice. This will involve the psychometric validation of the new illness-related distress measure to test how valid and reliable the measure is. The aim of the project is to provide initial validation of the Illness Related Distress Scale in a community sample, recruited through online platforms. The objective of the study is to gather initial validity and reliability data for the scale.

This cohort study implements patient reported outcome measures (PROMs) for patients with bodily stress syndrome in a clinic for functional disorders.
