Pain management in fibromyalgia

Metabolomics analysis of plasma samples of patients with fibromyalgia and electromagnetic sensitivity using GC-MS technique

Fibromyalgia (FM) is a chronic and systemic condition that causes widespread chronic pain, asthenia, and muscle stiffness, as well as in some cases depression, anxiety, and disorders of the autonomic system. The exact causes that lead to the development of FM are still unknown today. In a percentage of individuals, the symptoms of FM are often triggered and/or exacerbated by proximity to electrical and electromagnetic devices. Plasma metabolomic profile of 54 patients with fibromyalgia and self-reported electromagnetic sensitivity (IEI-EMF) were compared to 23 healthy subjects using gas chromatography-mass spectrometry (GC-MS) coupled with multivariate statistical analysis techniques. Before the GC-MS analysis the plasma samples were extracted with a modified Folch method and then derivatized with methoxamine hydrochloride in pyridine solution and N-trimethylsilyltrifuoroacetamide. The combined analysis allowed to identify a metabolomic profile able of distinguishing IEI-EMF patients and healthy subjects. IEI-EMF patients were therefore characterized by the alteration of 19 metabolites involved in different metabolic pathways such as energy metabolism, muscle, and pathways related to oxidative stress defense and chronic pain. The results obtained in this study complete the metabolomic "picture" previously investigated on the same cohort of IEI-EMF patients with ¹H-NMR spectroscopy, placing a further piece for better understanding the pathophysiological mechanisms in patients with IEI-EMF.

Effectiveness of non-pharmacological conservative therapies in adults with fibromyalgia: A systematic review of high-quality clinical trials

BACKGROUND

Fibromyalgia is a chronic condition characterized by generalized pain. Several studies have been conducted to assess the effects of non-pharmacological conservative therapies in fibromyalgia.

OBJECTIVE

To systematically review the effects of non-pharmacological conservative therapies in fibromyalgia patients.

METHODS

We searched MEDLINE, Cochrane library, Scopus and PEDro databases for randomized clinical trials related to non-pharmacological conservative therapies in adults with fibromyalgia. The PEDro scale was used for the methodological quality assessment. High-quality trials with a minimum score of 7 out of 10 were included. Outcome measures were pain intensity, pressure pain threshold, physical function, disability, sleep, fatigue and psychological distress.

RESULTS

Forty-six studies met the inclusion criteria. There was strong evidence about the next aspects. Combined exercise, aquatic exercise and other active therapies improved pain intensity, disability and physical function in the short term. Multimodal therapies reduced pain intensity in the short term, as well as disability in the short, medium and long term. Manual therapy, needling therapies and patient education provided benefits in the short term.

CONCLUSIONS

Strong evidence showed positive effects of non-pharmacological conservative therapies in the short term in fibromyalgia patients. Multimodal conservative therapies also could provide benefits in the medium and long term.

The management of fibromyalgia from a psychosomatic perspective: an overview

Fibromyalgia (FM) is a central sensitization syndrome characterized by chronic widespread pain. FM is often comorbid with psychiatric disorders, as well as psychological distress that worsens the quality-of-life of people affected. The aim was to collect current evidence about the management of FM from a psychosomatic perspective. The literature was synthesized and summarized in a narrative format. The literature search was carried out in PubMed; review articles, meta-analysis, overview, and guidelines published in the last 10 years written in English were included. Five main topics (Diagnostic criteria of FM; Pathogenesis of chronic widespread pain in FM; Early stress and trauma as predisposing factors for central sensitization; FM and Psychiatric comorbidity; Implications for treatment) were pointed out and discussed. Much evidence underlies the importance of considering and treating the comorbidity of FM with psychiatric disorders and psychological factors that affect pain management. Validation of FM as a central sensitization syndrome by a clinician facilitates therapeutic strategies that involve patients as active participants in the pain management process, likely leading to improved outcomes.
