Abstract
Fibromyalgia (FM) is a highly prevalent chronic disease. About 4.7% of the world's population suffers from generalized pain and hypersensitivity, in addition to a wide range of physical and psychological symptoms. The etiopathogenesis of this disease is multifactorial, which makes its diagnosis and treatment challenging. Recently, the increase in the number of studies on microbiota has provided new data that can help to understand the onset and development of FM. An updated systematic review of the causes of FM has been carried out in this work. Particularly in the last decade, research has focused on the gut-brain axis, which has emerged as a crucial mechanism for microbiota-host crosstalk. In FM patients, quantitative imbalances of the intestinal microbiota (dysbiosis) and bacterial metabolites with differential relative abundance have been found, especially short-chain fatty acids and lipopolysaccharides. Furthermore, the microbiota has been found to indirectly influence host neurotransmitter mechanisms, mainly through the serotonin precursor, glutamate, and gamma-aminobutyric acid. Thus, all these mechanisms and their influence on the etiopathogenesis of FM are discussed in this review.

Atamer Y, Sarac S, Asık HK, Sahbaz T. Serum paraoxonase activities, nitric oxide, and malondialdehyde levels are altered in patients with primary fibromyalgia syndrome. Ir J Med Sci 2023; 192:2541-2547.

Abstract
BACKGROUND Fibromyalgia patients who are exposed to extreme oxidative stress may face more severe clinical features or oxidative stress may be increased by the severity of the disease. AIM The purpose of these investigation were to determine serum paraoxonase activities (PON-1) and nitric oxide (NO) activities and malondialdehyde (MDA) level in fibromyalgia and whether there were any associations between these enzymes activities, MDA level, and clinical parameters. METHODS The study groups were consisted of 30 primer fibromyalgia patients and 30 healthy subjects. Clinical findings, pain severity, functional disability, general health status, anxiety, and depression assessed, and serum PON-1 activity, MDA, and NO levels were measured. RESULTS The primer fibromyalgia group had significantly higher MDA, low density lipoprotein-cholesterol (LDL-C), and decreased PON-1 activity, NO, and high density lipoprotein-cholesterol (HDL-C) with respect to controls. The paraoxonase activity was negatively correlated with MDA, LDL-C, Visual Analog Scale (VAS), Fibromyalgia Impact Questionnaire score (FIQ score), tender point score, age, and BDI score, while positively correlated with NO and HDL-C. MDA level was positively correlated with VAS, FIQ score, tender point score, age, and negatively correlated with NO level. CONCLUSION These results suggest that FMS patients have an alteration in levels of MDA, NO, and PON-1 activities. We think that impaired oxidant/antioxidant status may affect the symptoms of the disease. Also, they may be of importance in the complex physiopathologic mechanism behind the development of FMS.

Abstract
Aim: Still there is no any specific laboratory marker for diagnosis of FMS and it mainly depends on clinical examination. So that we aimed to evaluate whether serum Vitamin C levels and oxidative stress index (OSI) can be used in the diagnosis of Fibromyalgia Syndrome (FMS).
Material and Method: 53 female patients and 35 healthy female controls were enrolled to our cross-sectional study. VAS, BDI and FIQ were applied to the patients. Vitamin C levels were measured by HPLC. Total Antioxidant Capacity (TAC) and Total Oxidant Status (TOS) levels were determined by Spectrophotometric Assay method.
Results: While vitamin C and TAC levels of FMS patients were significantly lower than those of the controls, OSI was significantly higher in patients (p= 0.004, p= 0.009 and p= 0.048, respectively). There was a moderate positive and significant relationship between the tender points and FIQ, (r = 0.505; p

Abstract
Lyme disease results from a bacterial infection following a bite from an infected tick. Patients are initially treated with antibiotics; however, in cases where antibiotic treatment is delayed, or when patients do not respond to antibiotic treatment, fatigue may develop alongside problems affecting the nervous system, cardiovascular system, and joints. It is thought that most of the damage to these tissues results from the excessive inflammatory response of the host, involving a self-reinforcing cycle of mitochondrial dysfunction, oxidative stress and inflammation. In this article, we review the potential role of supplementary coenzyme Q10 (CoQ10) in mediating the pathogenic mechanism underlying Lyme disease, on the basis of its role in mitochondrial function, as well as its anti-inflammatory and antioxidant actions.

Abstract
This study aimed to investigate the levels of creatine (Cr) metabolites in the
anterior cingulate cortex (ACC), thalamus, and insula of patients with
fibromyalgia (FM) using proton magnetic resonance spectroscopy (MRS). The levels
of Cr and phosphocreatine (PCr) relative to total Cr (tCr), which includes Cr
and PCr, in the ACC, thalamus, and insula were determined using MRS in 12
patients with FM and in 13 healthy controls. The FM group had lower levels of
PCr/tCr in the ACC and right insula compared to healthy controls. There was a
negative correlation between Cr/tCr in the ACC and total pain levels (McGill
Pain Questionnaire-Total; r = −0.579, p = 0.049) and between Cr/tCr in the left
insula and affective pain levels (McGill Pain Questionnaire-Affective;
r = −0.638, p = 0.047) in patients with FM. In addition, there were negative
correlations between stress levels (Stress Response Inventory) and Cr/tCr in the
right (r = −0.780, p = 0.005) and left thalamus (r = −0.740, p = 0.006), as well
as in the right insula (r = −0.631, p = 0.028) in patients with FM. There were
negative correlations between symptom levels of post-traumatic stress disorder
(PTSD; PTSD checklist) and Cr/tCr in the right (r = −0.783, p = 0.004) and left
thalamus (r = −0.642, p = 0.024) of patients with FM. These findings are
paramount to understanding the decisive pathologies related to brain energy
metabolism in patients with FM.

Abstract
AIMS Oxidative stress increase is a key event for development of sensitivity-related illnesses (SRIs). The aim of this work was to evaluate the influence of a genetic variant in the antioxidant enzyme glutathione peroxidase (GPx1) on oxidative stress development in SRIs. MAIN METHODS GPx1 rs1800668 genotype, as well as glutathione, ubiquinone, and DNA damage were assessed in 34 SRI patients and 36 healthy subjects. KEY FINDINGS Total glutathione, reduced/oxidized glutathione, and ubiquinone were significantly decreased in cases compared with controls, while DNA fragmentation was significantly increased in patients. However, these differences were not associated to GPx1 genetic background. SIGNIFICANCE GPx1 rs1800668 polymorphism does not play a major role in SRI-related oxidative stress development.

Abstract
As the biological alarm of impending or actual tissue damage, pain is essential for our survival. However, when it is initiated and/or sustained by dysfunctional elements in the nociceptive system, it is itself a disease known as neuropathic pain. While the critical nociceptive system provides a number of protective functions, it is unique in its central role of monitoring, preserving and restoring the optical tear film in the face of evaporative attrition without which our vision would be non-functional. Meeting this existential need resulted in the evolution of the highly complex, powerful and sensitive dry eye alarm system integrated in the peripheral and central trigeminal sensory network. The clinical consequences of corneal damage to these nociceptive pathways are determined by the type and location of its pathological elements and can range from the spectrum known as dry eye disease to the centalised oculofacial neuropathic pain syndrome characterised by a striking disparity between the high intensity of symptoms and paucity of external signs. These changes parallel those observed in somatic neuropathic pain. When seen through the neuroscience lens, diseases responsible for inadequately explained chronic eye pain (including those described as dry eye) can take on new meanings that may clarify long-standing enigmas and point to new approaches for developing preventive, symptomatic and disease-modifying interventions for these currently refractory disorders.

Abstract
OBJECTIVE This study was performed to investigate serum prolidase enzyme activity and oxidative stress in patients diagnosed with fibromyalgia (FM). METHODS The study population consisted of 40 patients with a previous diagnosis of FM and 30 healthy subjects. We measured serum prolidase enzyme activity, total antioxidant status (TAS), total oxidative status (TOS), oxidative stress index (OSI), and paraoxonase-1 (PON-1) levels. RESULTS On average, FM patients were diagnosed within 3.2 years of symptom onset, and patients had a mean of 14 tender points. There were no significant differences between patients and controls in age, body mass index, serum TAS, or PON-1 levels. However, patients with FM demonstrated higher serum prolidase activity, TOS, and OSI than the control group. Serum prolidase activity was positively correlated with serum TOS, OSI, and visual analog scale pain and fatigue scores. No correlation was found between serum prolidase activity and FM duration or the average number of tender points. DISCUSSION Our results demonstrate a previously unreported association between serum prolidase enzyme activity and FM. Increased prolidase activity may contribute to the pathogenesis of FM, and measuring serum prolidase enzyme activity may be a useful FM biomarker.

Coenzyme Q10 depletion in medical and neuropsychiatric disorders: potential repercussions and therapeutic implications. Mol Neurobiol 2013; 48:883-903.

Abstract
Coenzyme Q10 (CoQ10) is an antioxidant, a membrane stabilizer, and a vital cofactor in the mitochondrial electron transport chain, enabling the generation of adenosine triphosphate. It additionally regulates gene expression and apoptosis; is an essential cofactor of uncoupling proteins; and has anti-inflammatory, redox modulatory, and neuroprotective effects. This paper reviews the known physiological role of CoQ10 in cellular metabolism, cell death, differentiation and gene regulation, and examines the potential repercussions of CoQ10 depletion including its role in illnesses such as Parkinson's disease, depression, myalgic encephalomyelitis/chronic fatigue syndrome, and fibromyalgia. CoQ10 depletion may play a role in the pathophysiology of these disorders by modulating cellular processes including hydrogen peroxide formation, gene regulation, cytoprotection, bioenegetic performance, and regulation of cellular metabolism. CoQ10 treatment improves quality of life in patients with Parkinson's disease and may play a role in delaying the progression of that disorder. Administration of CoQ10 has antidepressive effects. CoQ10 treatment significantly reduces fatigue and improves ergonomic performance during exercise and thus may have potential in alleviating the exercise intolerance and exhaustion displayed by people with myalgic encepholamyletis/chronic fatigue syndrome. Administration of CoQ10 improves hyperalgesia and quality of life in patients with fibromyalgia. The evidence base for the effectiveness of treatment with CoQ10 may be explained via its ability to ameliorate oxidative stress and protect mitochondria.

Abstract
Living with fibromyalgia means living with chronic pain, fatigue, sleep disorders and other associated key symptoms. To date, pharmacotherapy generally produces modest benefits. Some observations indicate that the large majority of symptoms of fibromyalgia could be the clinical manifestation of a mild thiamine deficiency due to a dysfunction of the active transport of thiamine from the blood to the mitochondria or to enzymatic abnormalities. Between June and July 2011, we recruited three female patients affected by fibromyalgia. We proceeded with the study of the patients' history, a physical examination, an evaluation of chronic widespread pain using the Visual Numeric Scale and an evaluation of the fatigue using the Fatigue Severity Scale were also performed. The levels of thiamine and thiamine pyrophosphate in the blood were determined. After the therapy with high doses of thiamine, in the patients, there was an appreciable improvement of the symptoms.

Abstract
Objetive: Fibromyalgia (FM) is a chronic pain syndrome with unknown etiology, which affects predominantly women. Mitochondrial alteration could have a role in the pathophysilogical mechanisms of inflammatory conditions as FM and periodontitis. The aim of the present study was assay the relationship between both diseases and mitochondrial dysfunction.
Patient and Methods: We study the presence of periodontitis in twelve patients diagnosed of FM and mitochondrial dysfunction described. The diagnosis of FM was established according to ACR criteria and clinical symptoms were evaluated using the Fibromyalgia Impact Questionnaire (FIQ) and Beck Depression Inventory (BDI).
Results: Only one patients of twelve included and agreed to participate in the study were diagnosed with periodontitis.
Conclusions: Pending studies with larger numbers of patients, we can conclude that mitochondrial dysfunction in FM is a itself event not related with periodontitis. Periodontitis could be considered a exclusion criterion in all studies about mitochondrial dysfunction in patients.

Abstract
Oxidative stress is a biochemical condition of imbalance between free radicals and antioxidant defence mechanisms. Cancer is an inducing oxidative stress disease. Metabolic changes in neoplastic cells, tumor infiltration by inflammatory cells, malnutrition and specific cancer treatment contribute to high levels of oxidative stress in cancer patients. The toxic effects of oxidative stress on normal cells could be counteracted by use of antioxidants, even though they may abrogate the harmful effects of oxidative stress on tumor cells and prevent apoptosis. Thus, currently, there is not enough scientific evidence to support the use of antioxidants in patients with cancer.

Abstract
BACKGROUND We examined lipid peroxidation (LPO) in blood mononuclear cells (BMCs) and plasma, as a marker of oxidative damage, and its association to clinical symptoms in Fibromyalgia (FM) patients. METHODS We conducted a case-control and correlational study comparing 65 patients and 45 healthy controls. Clinical parameters were evaluated using the Fibromyalgia Impact Questionnaire (FIQ), visual analogues scales (VAS), and the Beck Depression Inventory (BDI). Oxidative stress was determined by measuring LPO in BMCs and plasma. RESULTS We found increased LPO levels in BMCs and plasma from FM patients as compared to normal control (P<0.001). A significant correlation between LPO in BMCs and clinical parameters was observed (r = 0.584, P<0.001 for VAS; r = 0.823, P<0.001 for FIQ total score; and r = 0.875, P<0.01 for depression in the BDI). We also found a positive correlation between LPO in plasma and clinical symptoms (r = 0.452, P<0.001 for VAS; r = 0.578, P<0.001 for FIQ total score; and r = 0.579, P<0.001 for depression in the BDI). Partial correlation analysis controlling for age and BMI, and sex, showed that both LPO in cells and plasma were independently associated to clinical symptoms. However, LPO in cells, but not LPO in plasma, was independently associated to clinical symptoms when controlling for depression (BDI scores). DISCUSSION The results of this study suggest a role for oxidative stress in the pathophysiology of fibromyalgia and that LPO in BMCs rather than LPO in plasma is better associated to clinical symptoms in FM.
