reported levels of clinical pain have been shown to be associated with concentrations of corticotropin-releasing hormone (CRH) in the cerebrospinal fluid (CSF) [11] and to salivary cortisol levels [12].
It is, therefore, conceivable that fibromyalgia symptoms are associated with altered autonomic and HPA axis stress systems but that these altered stress systems do not necessarily cause the symptoms. Stress-related changes in other physiological systems, for example, neurotransmitter systems, might be additionally involved in symptom development.
Dysfunctional Neurotransmitter Systems in Fibromyalgia
Autonomic dysfunction in fibromyalgia syndrome: postural orthostatic tachycardia - PubMed
Although fibromyalgia (FM) syndrome is defined by chronic widespread pain and tenderness, additional symptoms, including disabling fatigue and dizziness, are often reported by patients with this chronic illness. Although nonrestorative sleep may play an important role for chronic fatigue in FM, othe …

Arterial Stiffness in Female Patients With Fibromyalgia and Its Relationship to Chronic Emotional and Physical Stress
In patients with fibromyalgia (FM) syndrome, stress and pain may chronically enhance sympathetic activity, altering cardiovascular responses and inducing the arterial wall-stiffening process. We investigated arterial stiffness in FM patients using ...
Evidence of both systemic inflammation and neuroinflammation in fibrom | JPR
Evidence of both systemic inflammation and neuroinflammation in fibromyalgia patients, as assessed by a multiplex protein panel applied to the cerebrospinal fluid and to plasma Emmanuel Bäckryd,1,* Lars Tanum,2,* Anne-Li Lind,3 Anders Larsson,4 Torsten Gordh,3 1Pain and Rehabilitation Center, Department of Medical and Health Sciences, Linköping University, Linköping, Sweden; 2Department of R&D in Mental Health, Akershus University Hospital, Lørenskog, Norway; 3Department of Surgical Sciences, 4Department of Medical Sciences, Uppsala University, Uppsala, Sweden *These authors contributed equally to this work Abstract: In addition to central hyperexcitability and impaired top–down modulation, chronic inflammation probably plays a role in the pathophysiology of fibromyalgia (FM). Indeed, on the basis of both animal experiments and human studies involving the analysis of cytokines and other inflammation-related proteins in different body fluids, neuroinflammatory mechanisms are considered to be central to the pathophysiology of many chronic pain conditions. However, concerning FM, previous human plasma/serum and/or cerebrospinal fluid (CSF) cytokine studies have looked only at a few predetermined cytokine candidates. Instead of analyzing only a few substances at a time, we used a new multiplex protein panel enabling simultaneous analysis of 92 inflammation-related proteins. Hence, we investigated the CSF and plasma inflammatory profiles of 40 FM patients compared with CSF from healthy controls (n=10) and plasma from blood donor controls (n=46). Using multivariate data analysis by projection, we found evidence of both neuroinflammation (as assessed in CSF) and chronic systemic inflammation (as assessed in plasma). Two groups of proteins (one for CSF and one for plasma) highly discriminating between patients and controls are presented. Notably, we found high levels of CSF chemokine CX3CL1 (also known as fractalkine). In addition, previous findings concerning IL-8 in FM were replicated, in both CSF and plasma. This is the first time that such an extensive inflammatory profile has been described for FM patients. Hence, FM seems to be characterized by objective biochemical alterations, and the lingering characterization of its mechanisms as essentially idiopathic or even psychogenic should be seen as definitively outdated.

Depression in Fibromyalgia Patients May Require Low-Dose Naltrexone to Respond: A Case Report
Fibromyalgia and depression are frequently comorbid. We propose a hormonal system model in understanding the underlying endogenous opioid system dysregulation in fibromyalgia with the utilization of the cold pressor test (CPT) in clinical practice ...
Modafinil Reduces Neuronal Pyroptosis and Cognitive Decline After Sleep Deprivation
Sleep deprivation (SD) induces systemic inflammation that promotes neuronal pyroptosis. The purpose of this study was to investigate the effect of an antioxidant modafinil on neuronal pyroptosis and cognitive decline following SD. Using a mouse model ...
reduced proinflammatory factor (IL-1β, TNF-α, and IL-6) production, and increased the expression of anti-inflammatory factors (IL-10).
This probably speaks to its role in combating pain in FMS.
Modafinil treatment attenuated inflammasome activity and reduced neuronal pyroptosis involving the NLRP3/NLRP1/NLRC4-caspase-1-IL-1β pathway
Impact of mast cells in fibromyalgia and low-grade chronic inflammation: Can IL-37 play a role? - PubMed
Fibromyalgia (FM) is a disease characterized by chronic widespread pain, fatigue, aches, joint stiffness, depression, cognitive dysfunction, and nonrestorative sleep. In FM, neurotransmission and glial activation can occur with an increase in inflammatory cytokines and involvement of mast cells (MCs …
T helper 1 response is correlated with widespread pain, fatigue, sleeping disorders and the quality of life in patients with fibromyalgia and is modulated by hyperbaric oxygen therapy - PubMed
FM patients show a Th1 signature and the activation of this subset is modulated by HBOT.
Objectives: Hyperbaric oxygen therapy (HBOT) has been used as treatment for different clinical conditions, including fibromyalgia (FM). HBOT modulates brain activity, ameliorates chronic pain and modifies the ratio of immune cells. Clinical studies have provided evidence that FM is associated with immune system dysregulation.
Results: Our results confirm the participation of immune system in the pathogenesis of FM and highlight the impact of HBOT treatment, with particular regard to the changes on proinflammatory cytokines production by CD4 T cells subsets.
Conclusions: FM patients show a Th1 signature and the activation of this subset is modulated by HBOT.

Significant lower plasma taurine, alanine, tyrosine (Tyr), valine, methionine, phenylalanine and threonine concentrations, and the sum of essential AAs were observed in FM patients vs healthy controls (P<0.05). Tyr CAA' ratio and the sum of AAs competing with tryptophan for brain uptake were significantly reduced in FM (P<0.05). A significant correlation was found between FM clinical parameters and certain AAs.
Our results suggest probable defects of gut malabsorption of certain AAs in FM patients.
